    Bu-Shen-Ning-Xin decoction (BSNXD), a traditional Chinese medicine, has been used to prevent and treat age-related diseases such as postmenopausal osteoporosis (PMO) for decades. This study sought to investigate the underlying mechanisms of BSNXD in terms of receptor activation of nuclear factor κB ligand (RANKL)-induced osteoclastogenesis in vitro because of the critical roles of bone resorption in the development and progression of osteoporosis. In mice, serum levels of dehydroepiandrosterone (DHEA), dehydroepiandrosterone sulfate (DHEAS), and 17-β-estradiol (E2) were evaluated with an enzyme immunoassay kit after ovariectomy. Levels of DHEA and DHEAS increased significantly following administration of BSNXD while the level of E2 did not. In addition, tartrate-resistance acid phosphatase staining showed that DHEA profoundly inhibited RANKL-induced osteoclastogenesis in vitro in a dose-dependent manner via estrogen receptor α (ERα) but not via estrogen receptor β or androgen receptors. Cytotoxicity was not detected in the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. These data suggest that BSNXD prevents PMO by increasing DHEA via the ERαpathway to suppress osteoclastogenesis.

    Osteoimmunology is a new discipline that focuses on the interaction between the bones and the immune system. Immune cells play an important role in bone metabolism. The aim of this study was to illustrate the effect of Bu-Shen-Ning-Xin Decoction (BSNXD) on lymphocytes in the spleen and bone marrow to explore the potential role on the bone. C57BL/6 mice were divided into four groups: sham, ovariectomized (OVX), OVX+BSNXD, and OVX+ estrogen. The sham and OVX groups were treated with saline, the OVX+BSNXD group was treated with BSNXD, and the OVX+ estrogen group was treated with estrogen. After mice were sacrificed, the spleens and bones were collected, and the lymphocytes in the spleen and bone marrow were analyzed. We found that BSNXD lessened the extent of the increase of CD4(+) and bone marrow. In contrast, these numbers were both increased in the OVX group. BSNXD had no influence on the percentage of γδ T cells. However, it increased the proportion of NK cells in the spleen and bone marrow. BSNXD lessened the extent of the increase of monocytes by ovariectomy. In vitro experiment, we found Tregs can decrease osteoclastogenesis when co-cultured with osteoclast precursor cells. This study suggests that BSNXD changes the immune environment and immune cells have a role in bone metabolism in OVX mice.

    Introduction Bu-Shen-Ning-Xin Decoction (BSNXD), a traditional Chinese medicinal composition, has been used as a remedy for postmenopausal osteoporosis, but its effects on bone metabolism and the uterus have not been reported. Purpose We aimed to determine the respective effects of BSNXD on the bones and the uterus of ovariectomized (OVX) mice to evaluate the efficacy and safety of this herbal formula. Materials and methods Postmenopausal osteoporosis animal models that were generated by ovariectomy were treated with BSNXD. Dual-energy X-ray absorptiometry was performed to analyze the bone mineral density, and histomorphometric analysis was performed to measure the parameters related to bone metabolism. Calcein labeling was performed to detect bone formation. The uteruses from the mice were weighed, and the histomorphometry was analyzed. Drug-derived serum was prepared to assess the 17-β-estradiol concentration via enzyme immunoassay. Results BSNXD administration ameliorated the osteoporotic phenotype of OVX mice, as evidenced by an increase in the bone mineral density and bone volume; these effects could not be abolished by the administration of the aromatase inhibitor letrozole. Moreover, BSNXD had no effect on the serum estrogen concentration or uterus. Conclusion These results suggest that BSNXD has ameliorating effects on bone loss due to estrogen deprivation without affecting the peripheral blood estrogen concentration or the uterus in OVX mice.

    Introduction Bu-Shen-Ning-Xin decoction (BSNXD) is a traditional Chinese medicinal composition that has been used as a remedy for postmenopausal osteoporosis, but the mechanisms affecting bone metabolism are not fully understood. Purpose We investigated the molecular mechanism and signaling pathway underlying the effect of BSNXD on osteoclastogenesis. Materials and methods A postmenopausal osteoporosis animal model generated by ovariectomy was administered BSNXD and drug-derived serum was prepared. An enzyme immunoassay was conducted to measure the 17-β-estradiol (E2) concentration in the drug-derived serum. Bone marrow-derived monocyte/macrophage precursor cells were treated with drug-derived serum, and tartrate-resistance acid phosphatase staining was conducted to observe osteoclastogenesis. A bone resorption assay was performed to analyze the effect on osteoclastic resorptive function. Real-time PCR, flow cytometry, Western blotting, transfection, and luciferase assays were conducted to explore the related mechanism. Results E2 was not elevated in BSNXD-derived serum. BSNXD-derived serum suppressed receptor activation of nuclear factor κB ligand (RANKL)-activated osteoclastogenesis in a dose-dependent manner; this effect could be reversed by estrogen receptor α antagonist methyl-piperidino-pyrazole. The serum suppressed RANKL-induced NF-κB transcription and inhibited the accumulation of nuclear factor of activated T-cells, cytoplasmic 1 in osteoclast precursor cells; the inhibitory effect was abolished by methyl-piperidino-pyrazole but not the estrogen receptor β antagonist or androgen receptor antagonist. Conclusion These results collectively suggest that administration of BSNXD presents inhibitory effects on osteoclast differentiation by abrogating the RANKL-induced nuclear factor of activated T-cells, cytoplasmic 1 and NF-κB signaling pathways downstream of estrogen receptor α, thereby contributing to the inhibitory effect on bone resorption.

    Recently, GONG started recording regular noon drift-scans throughout the Network (3 per week). This is in an effort to prevent spurious "wobbling" of GONG's merged images by providing regular "reality checks" on the true orientation of the site images. Wobbling can be very detrimental to local helioseismology analyses (A.K.A. the "Washing Machine Effect") Here we describe recent steps to automate the processing of the drift-scans once they arrive in Tucson.

    Helioseismology requires nearly continuous observations of the oscillations of the solar surface for long periods of time in order to obtain precise measurements of the sun's normal modes of oscillation. The GONG project acquires velocity images from a network of six identical instruments distributed around the world. The GONG network began full operation in October 1995. It has achieved a duty cycle of 89 percent and reduced the magnitude of spectral artifacts by a factor of 280 in power, compared with single-site observations. The instrumental noise is less than the observed solar background.

    2013-06-01

    A challenge of the past few decades for the Solar Observing Optical Network (SOON), operated by the United States Air Force Weather Agency (AFWA), has been to obtain consistent flare brightness reporting for the same flare from different sites. Flare area is usually considered to be a more reliable measure, but significant variation of values between sites still occurs. The Global Oscillation Network Group (GONG) deployed a Hα patrol system in 2010. This provides a modern system with near identical equipment to compare flares from six different sites. The classification of flares and techniques of flare measurement will be briefly discussed. The results presented here suggest that even though different GONG sites report different flare areas and brightnesses, for some sites they vary in a consistent way allowing correction factors to be applied.

    Thermographic technique can be used to measure temperature distribution of body surface in real-time, non-contact and full-field, which has been successfully used in medical diagnosis, remote sensing, and NDT, etc. The authors have developed a thermographic experiment that can be applied to inspect the effect of action of acupuncture and qi-gong (a system of deep breathing exercises) by measuring the temperature of hand and arm. The observation is performed respectively by thermography for the dynamic changes of temperature of the arm and hand after acupuncture therapy and qi-gong therapy. Thermographic results show that the temperature on the collateral channels increases markedly. In the meantime, it can be seen that the above therapies of Chinese medicine can stimulate the channel collateral system. This also contributes a new basis to the effect of action of the therapies of Chinese medicine. The work shows that thermographic technique is a powerful tool for research in Chinese medicine. In this paper, some thermal images are obtained from the persons treated with acupuncture and qi- gong.

    Changes taking place in both Qi Gong Masters and their patients during Qi Gong treatment were evaluated using the Bi-Digital O-Ring Test. During the Qi Gong state, on the Qi-Gong Master's body, as well as the body of the patient being treated, acupuncture points CV5 (Shi Men) and CV6 (Qi Hai)-- located below the umbilicus-- show changes from +4 in the pre-Qi Gong state to between -3 and -4 during the Qi Gong state. Before and after the Qi Gong, there is a normal +4 response to the Bi-Digital O-Ring Test at these acupuncture points. Similar changes were also observed on acupuncture points CV17 (Shan Zhong), CV 22 (Tian Tu), Yin Tang (at an area just between the eyebrows: the pituitary gland representation area, colloquially known as the "third eye") and GV20(Bai Hui), the entire pericardium meridian & triple burner meridian, their acupuncture points, the adrenal glands, testes, ovaries and perineum, as well as along the entire spinal vertebrae, particularly on and above the 12th thoracic vertebra, medulla oblongata, pons, and the intestinal representation areas of the brain located just above and behind the upper ear. Using these findings as criteria for evaluating the effectiveness of reaching the Qi Gong state, we were able to reproduce during the experimental trials similar changes in ourselves and the patient being treated with therapeutic effects comparable to those of the Qi Gong Master. Beneficial effects of external Qi Gong treatment given by a Qi Gong practitioner 1 to 3 times for 10-20 seconds each (although most Qi Gong masters take 3-20 minutes per treatment) often resulted in improvement of circulation and lowering of high blood pressure, as well as relaxation of spastic muscles, relief of pain, and enhanced general well-being, all of which resemble acupuncture effects. In order to reproduce the same procedure with others, we selected 4 children ranging between 8 and 11 years of age who had no knowledge of Qi Gong or Oriental medicine. One of these four

    Studies have been made of the normal modes of a 20.7 cm diameter steel gamelan gong. A finite-element model has been constructed and its predictions for normal modes compared with experimental results obtained using electronic speckle pattern interferometry. Agreement was reasonable in view of the lack of precision in the manufacture of the instrument. The results agree with expectations for an axially symmetric system subject to small symmetry breaking. The extent to which the results obey Chladni's law is discussed. Comparison with vibrational and acoustical spectra enabled the identification of the small number of modes responsible for the sound output when played normally. Evidence of non-linear behavior was found, mainly in the form of subharmonics of true modes. Experiments using scanning laser Doppler vibrometry gave satisfactory agreement with the other methods.

  12. Nearly steady flows in GONG prototype data

    1993-01-01

    Doppler velocity images obtained with the GONG prototype instrument were analyzed to measure the nearly steady photospheric flows. The data consists of 88 images each of velocity, intensity, and modulation obtained at 20:00 UT on 88 days from July 1992 to February 1994. Each velocity image was temporally filtered to remove the p-mode oscillations, masked to exclude active regions, and then analyzed using spherical harmonics and orthogonal functions as described by Hathaway (1992). The spectral coefficients show very consistent results for the entire time interval with some evidence of year-to-year variations. The rotation profile agrees well with previous results and exhibits a north-south asymmetry that reverses sign during the 20 month interval. The residual rotation velocities exhibit structures with amplitudes of approximately 5 m/s that may be related to torsional oscillations. The meridional circulation is directed from the equator toward the poles with a peak velocity in the photosphere of approximately 50 m/s. The higher order components are very weak but indicate a divergent flow from the mid-latitudes (opposite that found for the June 1989 data). The convective limb shift is well fit by a 3rd order polynomial. The convection spectrum has a prominent peak at spherical harmonic degrees of l approximately 150 with very little signal in the low degree modes. Analysis of this signal shows that there is no evidence for giant cell convection at the level of approximately 10 m/s for all modes up to l = 32.

    Using Severino's model, we estimate the amount of coherent correlated and uncorrelated background and incoherent noise components needed to reproduce the following four helioseismic spectra: V power, I power, V I phase difference and V I coherence, using GONG and MDI data. We confirm that a coherent correlated component of 10-15% of the total background and noise is needed in both V and I and that a larger amount of coherent uncorrelated background is needed for MDI data compared to GONG data to compensate for a smaller incoherent noise.

    The mouse Xin repeat-containing proteins (mXinalpha and mXinbeta) localize to the intercalated disc in the heart. mXinalpha is able to bundle actin filaments and to interact with beta-catenin, suggesting a role in linking the actin cytoskeleton to N-cadherin/beta-catenin adhesion. mXinalpha-null mouse hearts display progressively ultrastructural alterations at the intercalated discs, and develop cardiac hypertrophy and cardiomyopathy with conduction defects. The up-regulation of mXinbeta in mXinalpha-deficient mice suggests a partial compensation for the loss of mXinalpha. To elucidate the evolutionary relationship between these proteins and to identify the origin of Xin, a phylogenetic analysis was done with 40 vertebrate Xins. Our results show that the ancestral Xin originated prior to the emergence of lamprey and subsequently underwent gene duplication early in the vertebrate lineage. A subsequent teleost-specific genome duplication resulted in most teleosts encoding at least three genes. All Xins contain a highly conserved beta-catenin-binding domain within the Xin repeat region. Similar to mouse Xins, chicken, frog and zebrafish Xins also co-localized with beta-catenin to structures that appear to be the intercalated disc. A putative DNA-binding domain in the N-terminus of all Xins is strongly conserved, whereas the previously characterized Mena/VASP-binding domain is a derived trait found only in Xinalphas from placental mammals. In the C-terminus, Xinalphas and Xinbetas are more divergent relative to each other but each isoform from mammals shows a high degree of within-isoform sequence identity. This suggests different but conserved functions for mammalian Xinalpha and Xinbeta. Interestingly, the origin of Xin ca. 550 million years ago coincides with the genesis of heart chambers with complete endothelial and myocardial layers. We postulate that the emergence of the Xin paralogs and their functional differentiation may have played a key role in the

    Although the origin of many common modern medicines that are routinely being used nowadays in healthcare is in medicinal plants and fungi, herbal medicine as a standalone profession is no longer included in the curricula of most Western medical schools. The medicinal plant Lei Gong Teng [also known as Thunder God Vine, Tripterygium Wilfordii Hook f., that is core to traditional Chinese herbal medicine, was praised for its possible anti-inflammatory properties in ancient traditional scripts that date back thousands of years. Yet, modern interest in its proven immune-modulatory properties serves as a vivid example to the bridge that is being built, gradually but constantly, between the tradition of healing arts and the world of modern therapeutics. In this review we summarize the main findings from an increasing number of clinical and laboratory studies published in top peer-reviewed medical journals that verify the traditional indications for which Lei Gong Teng was used medicinally. Based on these findings, and the risk-benefit profile of the plant's debarked root, we conclude that Lei Gong Teng and its active metabolites should be included in the Israeli herbal pharmacopeia.

    The NOAA Space Weather Prediction Center (SWPC) is the nation's official source of space weather watches, warnings, and alerts, providing 24x7 forecasting and support to critical infrastructure operators around the world. Observations of the conditions on the Sun are crucial for determining when and if a warning is needed. The Global Oscillation Network Group (GONG) operated by the National Solar Observatory (NSO) consists of six ground stations, allowing continuous observations of the Sun. Of particular interest for space weather purposes are the H-alpha images and magnetograms. The H-alpha data are used to identify filaments and their eruptions, to assess active region evolution and plage extent, and to help localize flare locations. The magnetograms are used to identify neutral lines, to examine potential shearing areas and to characterize the magnetic structure of active regions. GONG magnetograms also provide the initial condition for models of solar wind expansion through the heliosphere such as the WSA-Enlil model. Although beyond the scope of current space weather applications, GONG helioseismology products can be used to assess active region emergence on the far side of the Sun and to indicate the flaring potential of a front-side active region. These products are being examined as future tools in flare prediction.NSO has operated GONG as a science facility since 1995 and has provided processed space weather data products to NOAA via for the past several years.

    Since mid-2010 the Global Oscillation Network Group (GONG) has collected H-alpha images at six sites around the world. These images provide a near real-time solar activity patrol for use in space weather applications and also an archive for research purposes. Images are collected once per minute, dark, smear, and flat corrected, compressed and then sent via the Internet to a 'cloud' server where reduction is completed. Various reduced images are usually available within a minute after exposure. The H-alpha system is an add-on to the normal GONG helioseismology instrument and does not interfere with regular observations. A polarizing beamsplitter sends otherwise unused 656 nm light through two lenses to a Daystar 0.04 nm mica etalon filter. The filter is matched to an image of the GONG light feed entrance pupil and sees an image of the Sun at infinity. Two lenses behind the filter form the solar image on a DVC-4000 2k x 2k interline transfer CCD camera. Exposure times are automatically adjusted to maintain the quiet disk center at 20% of full dynamic range to avoid saturation by bright flares. Image resolution is limited by diffraction, seeing and some high-order wavefront errors in the filters. A unique dual-heater system was developed by Daystar to homogenize the passband characteristics of the mica etalons. The data are in regular use for space weather forecasting by the U.S. Air Force Weather Agency, which funded construction and installation of the instruments. Operational and reduction improvements are underway and archived data are already being used for research projects. The Web site URL is http://halpha.nso.edu.

    The specimens of lei-gong-mo (tektites) were collected from Hainan Island and Leizhow Peninsula during the period from 1963 to 1975. The distribution, forms, sculpture, abration surface (bald spot), internal structure and chemical composition of lei-gong-mo are discussed. Studies of these materials lead to the following conclusions: (1) the specimens of lei-gong-mo can be morphologically divided into eight types; (2) the sculptures on the surface of lei-gong-mo are probably due to the corrosion effect of volcanic gas, and the abration surface due to the aerodynamic corrosion; (3) the folded structures in the layered lei-gong-mo (Muong Nong-type tektite) seem hardly to be formed by an impact of meteorites, but they might be produced in the magma flow process when the lei-gong-mo was melting within the crater vent; and (4) the comparison of its chemical composition with that of basalt from Hainan Island does not show that lei-gong-mo came from the local volcano. The hypothesis of the lunar volcanic origin of tektites is examined.

    Xin is a striated muscle-specific actin-binding protein whose mRNA expression has been observed in damaged skeletal muscle. Here we demonstrate increased Xin protein expression early postinjury (≤ 12 h) and localization primarily to the periphery of damaged myofibers. At 1 day postinjury, Xin is colocalized with MyoD, confirming expression in activated satellite cells (SCs). By 5 days postinjury, Xin is evident in newly regenerated myofibers, with a return to preinjury levels by 14 days of regeneration. To determine whether the increased Xin expression is functionally relevant, tibialis anterior muscles of wild-type mice were infected with Xin-short hairpin RNA (shRNA) adenovirus, whereas the contralateral tibialis anterior received control adenovirus (Control). Four days postinfection, muscles were harvested or injured with cardiotoxin and collected at 3, 5, or 14 days thereafter. When compared with Control, Xin-shRNA infection attenuated muscle regeneration as demonstrated by Myh3 expression and fiber areas. Given the colocalization of Xin and MyoD, we isolated single myofibers from infected muscles to investigate the effect of silencing Xin on SC function. Relative to Control, SC activation, but not proliferation, was significantly impaired in Xin-shRNA-infected muscles. To determine whether Xin affects the G0-G1 transition, cell cycle reentry was assessed on infected C2C12 myoblasts using a methylcellulose assay. No difference in reentry was noted between groups, suggesting that Xin contributes to SC activation by means other than affecting G0-G1 transition. Together these data demonstrate a critical role for Xin in SC activation and reduction in Xin expression results in attenuated skeletal muscle repair.

    ABSTRACT The taboos of man-spirit (RenShen) and bottom-spirit (KaoShen) are two kinds of time-related contraindications that are more commonly seen in the literature of acupuncture and moxibustion. The meaning of man-spirit is often extended to qi-blood or mind, or else directly equals to heaven-spirit (TianShen). It is highly possible that the bottom-spirit is subordinate to man-spirit, and both Taoist philosophy and the SanCai theory declare the importance of bottom in human body. The violation of contraindications could lead to diseases in the neighborhood where man-spirit travels. However, the results are generally recorded as ulcer, lingering disease and death in most medical texts. From Ming dynasty, more and more doctors have expressed disapproval of man-spirit and bottom-spirit.

    We consider the spatially-varying Burgers equation in one dimension. We take the Lax–Friedrichs finite volume method and Jin–Xin relaxation method in solving the equation. According to our research, the Jin–Xin relaxation method produces a more accurate solution, as they produce smaller error than the Lax–Friedrichs finite volume method. However, the Lax–Friedrichs finite volume method is faster in computation than the Jin–Xin method.

    This study describes two similar approaches to human movement: Qi Gong exercises and the Feldenkrais method. These systems are investigated in terms of Gestalt concepts and humanistic psychology. Moshe Feldenkrais created the concept known as Awareness Through Movement. This concept assumes that by becoming more aware of one's movements, one functions at a higher level. In similar ways to those using the Feldenkrais method, individuals may become more aware of their own movements by performing Qi Gong exercises: A therapeutic modality that facilitates mind-body integration. Qi Gong exercises commonly lead to increased personal awareness accompained by enhanced quality, fluency and smoothness of movement. These two methods of movement therapies are explored in terms of their relations with Gestalt concept and humanistic psychology.

    The data of ground-based telescopes of the Global Oscillation Network Group (GONG) obtained in the Hα line provide an opportunity to study the long-period oscillations of chromospheric filaments (quiescent prominences). For the first time, on the basis of time series of 5 days duration that we combined from the observations of three observatories of the GONG network, a new ultra-low mode with a period of between 20 and 30 hours was reliably detected in oscillations of a long-lived dark filament on the solar disk.

    Samples of Magnolia biondii buds (Xin Yi, Flos Magnoliae) from different sources were subjected to phytochemical analysis and compared to samples of M. denudata and M. liliiflora. Among the compounds found in the flower buds of M. biondii were eight tetrahydrofurofuran lignans as well as the sesquiterpene lactone parthenolide and the sesquiterpene alcohol oplodiol. A rapid TLC-method for the identification of plant material from M. biondii and its distinction from M. liliiflora was developed. Structure elucidation was carried out by means of NMR (1- and 2-D) and LC-MS.

  14. MERIDIONAL FLOW IN THE SOLAR CONVECTION ZONE. II. HELIOSEISMIC INVERSIONS OF GONG DATA

    2015-06-01

    Meridional flow is thought to play a very important role in the dynamics of the solar convection zone; however, because of its relatively small amplitude, precisely measuring it poses a significant challenge. Here we present a complete time–distance helioseismic analysis of about 2 years of ground-based Global Oscillation Network Group (GONG) Doppler data to retrieve the meridional circulation profile for modest latitudes in an attempt to corroborate results from other studies. We use an empirical correction to the travel times due to an unknown center-to-limb systematic effect. The helioseismic inversion procedure is first tested and reasonably validated on artificial data from a large-scale numerical simulation followed by a test to broadly recover the solar differential rotation found from global seismology. From GONG data, we measure poleward photospheric flows at all latitudes with properties that are comparable with earlier studies and a shallow equatorward flow about 65 Mm beneath the surface, in agreement with recent findings from Helioseismic and Magnetic Imager (HMI) data. No strong evidence of multiple circulation cells in depth or latitude is found, yet the whole phase space has not yet been explored. Tests of mass flux conservation are then carried out on the inferred GONG and HMI flows and compared to a fiducial numerical baseline from models, and we find that the continuity equation is poorly satisfied. While the two disparate data sets do give similar results for about the outer 15% of the interior radius, the total inverted circulation pattern appears to be unphysical in terms of mass conservation when interpreted over modest time scales. We can likely attribute this to both the influence of realization noise and subtle effects in the data and measurement procedure.

    Shen-Min is a herbal product sold as a supplement for women to enhance hair growth. It is widely available across Asia, Europe, and the United States and sold without prescription as a hair nutritional supplement. We describe a case of acute liver injury in a 28-year-old white woman who developed symptomatic hepatitis 8 weeks after starting Shen-Min. All other potential causes of acute hepatitis including viral, hypoxic/ischemic, metabolic, and autoimmune etiologies were excluded. The liver injury slowly resolved over 3 weeks after discontinuing the herbal product. Although the mechanism of Shen-Min hepatotoxicity is unknown, we suspect an idiosyncratic reaction because the patient developed a fine maculopapular rash, mild eosinophilia, and did not overdose. Shen-Min is a Chinese herbal product with a mixture of several plants and vitamins including Polygonum multiflorum, a root that has been previously associated with hepatotoxicity. Nonetheless to our knowledge this is the first reported case of herbal-induced hepatotoxicity in a patient taking Shen-Min per se. Clinicians taking care of patients with acute hepatitis of unclear etiology should be aware that the consumption of Shen-Min, a hair supplement widely available in the United States and Western countries might cause acute hepatitis.

    YANG XIN is a traditional Chinese medicine formulation used for nervous fatigue and consists of a proprietary blend of concentrated extracts from 18 plant ingredients. The 18 constituent plant ingredients, YANG XIN capsules, and formulations 2014-005_1 A and 1B were extracted by consecutive 24-hour macerations with dichloromethane followed by methanol. Metabolite separation was carried out through LC-MS in 40 minutes. Data acquisitions for qualitative and quantitative analyses of the samples were collected under (±) ESI modes and (+) APCI mode using full spectrum scan analysis.A total of 18 analytical markers were identified by LC-MS for YANG XIN formulations based on accurate mass measurements, molecular formula, double bond equivalent, MFG score, and error (ppm) of the measurement. Aditionally, a comparison of the data with previously reported results for the compounds, followed by identity confirmation with standard compounds, was performed. Seventeen analytical markers representing 17 plant ingredients in the different YANG XIN formulations were quantified for the first time. The YANG XIN capsules and the 2014-005_1B formulation were similar to each other and different from the 2014-005_1 A formulation based on the fact that both YANG XIN capsules and the 2014-005_1B formulation contain the same analytical markers. This method provides good linearity (r(2) > 0.9945), intraday precision (R. S. D. < 3.9 %), interday precision (R. S. D. < 5.6 %), accuracy (99.2-101 %), recovery (145.7 %), limit of detection (0.0011-0.0732 µg/mL), and limit of quantitation (0.0038-0.2441 µg/mL).

    We search for a solar cycle variation in mode widths and amplitudes derived from 3-month GONG time series. The variation of mode width and amplitude observed in GONG data are the combined effects of fill factor, temporal variation, and measurement uncertainties. The largest variation is caused by the fill factor resulting in modes with increased width and reduced amplitude when fill is lower. We assume that the solar cycle variation is the only other systematic variation beside the temporal window function effect. We correct all currently available data sets for the fill factor and simultaneously derive the solar cycle variation. We find an increase of about 3% on average in mode width from the previous minimum to Oct. 1998 and a decrease of about 7% and 6% in mode amplitude and mode area (width x amplitude). We find no l dependence of the solar-cycle changes. As a function of frequency, these changes show a maximum between 2.7 and 3.3 mHz with about 47% higher than average values for mode width and about 29% and 36% higher ones for mode amplitude and area. We estimate the significance of these rather small changes by a pre-whitening method and find that the results are significant at or above the 99.9% level with mode area showing the highest level of significance and mode width the lowest. The variation in background amplitude is most likely not significant and is consistent with a zero change.

    Time series of full-disk Dopplergrams were acquired at the 60-Foot Solar tower of the Mount Wilson Observatory every year between 1987 and 2009. Analysis of this archive revealed that the focal plane of the Tower did experience a small amount of systematic rotation, which suggested that the alignment of the optics had changed slightly over the years since its construction in 1907. This has caused some of the initial daily flow maps to possess a so-called “washing machine” effect similar to the pattern that was seen in raw GONG flow maps. We have incorporated a systematic program of ring-diagram analysis in which we have tracked the raw solar images using five differing assumed instrumental rotation rates. We have then gone on to compute synoptic maps of the horizontal flow vectors at several different depths over much of Solar Cycle 23 in order to study how such an instrumental rotation might affect both the zonal and meridional flows as functions of latitude, depth, and time. We compare these results with GONG and MDI flow measurements to empirically determine the regime within which the MWO results are reliable and extend our analysis into Solar Cycle 22.

    The effect of Shen'an granules on the Wnt signaling pathway in renal tissues of mouse models of streptozotocin (STZ)-induced diabetic nephropathy was investigated in the present study. A total of 62 BALB/c mice were randomly divided into the normal control (A group), model (B group), losartan (C group), low-dose Shen'an granules (D group), and high-dose Shen'an granules (E group) groups. The mouse model of diabetic nephropathy was established by a single intraperitoneal injection of STZ (150 mg/kg). The animals were treated with drugs for 8 weeks, and blood creatinine, blood urea nitrogen, triglycerides (TG), and total cholesterol (CHOL) were measured prior to and after treatment. PAS staining was performed for observation of glomerular microstructure by light microscope, and western blot analysis was performed to detect Wnt1 protein and β-catenin protein. The results indicated that the quantification of 24-h microalbuminuria, and levels of blood creatinine, urea nitrogen, TG, and CHOL were significantly lower in the high- and low-dose Shen'an granules groups than those in the model group (p<0.05). The expression levels of Wnt1 protein and β-catenin protein in the high- and low-dose Shen'an granules groups were significantly lower than those in the model group (p<0.05). In conclusion, proteinuria, renal dysfunction, and dyslipidemias are closely associated with the abnormal activation of the Wnt signaling pathway in the mouse model of diabetic nephropathy. The mechanism by which Shen'an granules regulate proteinuria, renal function, and blood lipids may be associated with inhibition of the abnormally activated Wnt signaling pathway. PMID:28105085

    Some of the most challenging observations to explain in the context of existing flare models are those related to the lower atmosphere and below the solar surface. Such observations, including changes in the photospheric magnetic field and seismic emission, indicate the poorly understood connections between energy release in the corona and its impact in the photosphere and the solar interior. Using data from Hinode, TRACE, RHESSI, and GONG we study the temporal and spatial evolution of the 2006 December 14 X-class flare in the chromosphere, photosphere, and the solar interior. We investigate the connections between the emission at various atmospheric depths, including acoustic signatures obtained by time-distance and holography methods from the GONG data. We report the horizontal displacements observed in the photosphere linked to the timing and locations of the acoustic signatures we believe to be associated with this flare, their vertical and horizontal displacement velocities, and their potential implications for current models of flare dynamics.

    Gong kiln, for its long porcelain-firing history, was one of three representative white porcelain kilns in northern China. In order to improve the quality and whiteness of white porcelain, a decorating layer or cosmetic earth was laid on the body surface in Gong kiln during early Tang dynasty, which was able to blot out rough surface and weaken the influence of fuscous body upon surface color. In this paper the main chemical composition of the white porcelain's profile was analyzed by using energy disperse X-Ray fluorescence. The result showed that different materials were used as cosmetic earth during early Tang dynasty, in accordance with the phenomenon under optical microscope. In addition, the glaze belongs to calcium glaze in which plant ash was added.

    The exploration of undersea resources becomes popular as land resources decrease. Researches were conducted with emphasis on the safety and efficiency of undersea mining of the large gold deposit in Xinli District of Sanshandao Gold Mine. A series of tests for the physical and mechanical characteristics of rock mass were carried out, and the three-dimensional geo-stress distribution was tested in the mining area. Further, a similar experimental simulation platform, which revealed the mechanism of water inrush and ascertained the reasonable thickness of the safety isolate layer, was established for the undersea mining. Meanwhile, the feasibility of cancelling the ore pillars and the safety conditions was checked by numerical simulation. The simulation results show that it is safe to exploit the ore body below the -85 m level (presently, the exploitation level is below -160 m in Xinli District), and the ore pillars can be cancelled below the -560 m level. Furthermore, a novel backfill method was designed to reduce the rock strata disturbance and settlement, and the settlement of roof strata was monitored during the mining process. Engineering practice shows that the settlement of roof strata was small and that no disaster happened. This indicates that the undersea safety mining technology of the large gold deposit is achieved in Xinli District.

  4. Using SDO and GONG as Calibration References for a New Telescope Pointing Algorithm

    Long duration observations are a basic requirement for most types of helioseismic measurements. Pointing stability and the quality of guiding is thus an important issue with respect to the spatio-temporal analysis of any velocity datasets. Existing pointing tools and correlation-tracking devices will help to remove most of the spatial deviations building up during an observation with time. Yet most ground- and space-based high-resolution solar telescopes may be subject to slow image-plane drift that cannot be compensated for by guiding and which may accumulate to displacements of 10″ or more during a 10-hour recording. We have developed a new pointing model for solar telescopes that may overcome these inherent guiding-limitations. We have tested the model at the Vacuum Tower Telescope (VTT), Tenerife. We are using SDO and GONG full-disk imaging as a calibration reference. We describe the algorithms developed and used during the tests. We present our first results. We describe possible future applications as to be implemented at the VTT. So far, improvements over classical limb-guider systems by a factor of 10 or more seem possible.

    On the base of establishing the fingerprint of JinKui ShenQi pills, the ultraviolet spectra-mass spectrometry/mass spectrometry, method was used to identify the fingerprint. Seperation was performed on the Symmetry Shield RP18 (5 microm, 4. 6 mm X 15 mm) analytical column with mobile phase consisting of 1% acetic acid and acetonitrile with gradient elute at the flow rate of 1.0 mL x min(-1), and the ultraviolet detection wavelength was set at 248 nm. Using the above-mentioned chromatographic condition, the fingerprint of different samples was established and the same fingerprint was defined. The fingerprints of different samples were compared with similarity evaluation software published by Pharmacopeia committee codex (2004A). The mass spectrograph with API-ESI ionization source was used, setting the flow rate at 0.5 mL x min(-1) after splitting stream. The pressure of atomization room was 50 Psi, the flow rate of dry gas was 9.0 L x min(-1), the capillary voltage was 4 kV, and the transmission voltage was 70 V. The negative scanner mode was chosen, scan scope was 100-2000, using ion trap to analyze quasimolecular ion peak and the selected fragment ion, and TIC chromatography and second order mass chromatogram were recorded. The major constituents among in JinKui ShenQi pills from different origins were separated well by HPLC. Although there was difference among different origins, they showed nineteen identical characteristic absorption bands. Three fingerprints chemical compositions such as loganin, cinnamal and paeonol were identified based on the retention time and ultraviolet spectra of standard preparation. According to their ultraviolet spectra, molecular weight and fragmentation information, ten peaks in the fingerprint were identified by ultraviolet spectroscopy-mass, spectrometry/massg spectrometry. They are 1,2,3-tri-O-galloyl-glucose, loganin, paeoniflorin, 1,2,3,6-tetro-O-galloyl-glucose, soya-cerebroside, cornuside, and PGG, benzoyl

    Approximately one-third of known deafness genes encode proteins located in the hair bundle, the sensory hair cell's mechanoreceptive organelle. In previous studies, we used mass spectrometry to characterize the hair bundle's proteome, resulting in the discovery of novel bundle proteins. One such protein is Xin-actin binding repeat containing 2 (XIRP2), an actin-cross-linking protein previously reported to be specifically expressed in striated muscle. Because mutations in other actin-cross-linkers result in hearing loss, we investigated the role of XIRP2 in hearing function. In the inner ear, XIRP2 is specifically expressed in hair cells, colocalizing with actin-rich structures in bundles, the underlying cuticular plate, and the circumferential actin belt. Analysis using peptide mass spectrometry revealed that the bundle harbors a previously uncharacterized XIRP2 splice variant, suggesting XIRP2's role in the hair cell differs significantly from that reported in myocytes. To determine the role of XIRP2 in hearing, we applied clustered regularly interspaced short palindromic repeat (CRISPR)/Cas9-mediated genome-editing technology to induce targeted mutations into the mouse Xirp2 gene, resulting in the elimination of XIRP2 protein expression in the inner ear. Functional analysis of hearing in the resulting Xirp2-null mice revealed high-frequency hearing loss, and ultrastructural scanning electron microscopy analyses of hair cells demonstrated stereocilia degeneration in these mice. We thus conclude that XIRP2 is required for long-term maintenance of hair cell stereocilia, and that its dysfunction causes hearing loss in the mouse.

    Highlights: Black-Right-Pointing-Pointer Conditional medium and dan-shen root were used for cardiomyogenic differentiation. Black-Right-Pointing-Pointer They all could induce hPDMSCs to differentiate into cardiomyocytes. Black-Right-Pointing-Pointer The induction effect of the latter was slightly higher compared to that of the former. Black-Right-Pointing-Pointer Dan-shen root could be a good inducer for cardiomyogenic differentiation. -- Abstract: The aim of this study was to search for a good inducer agent using for cardiomyogenic differentiation of stem cells. Human placenta-derived mesenchymal stem cells (hPDMSCs) were isolated and incubated in enriched medium. Fourth passaged cells were treated with 10 mg/L dan-shen root for 20 days. Morphologic characteristics were analyzed by confocal and electron microscopy. Expression of {alpha}-sarcomeric actin was analyzed by immunohistochemistry. Expression of cardiac troponin-I (TnI) was analyzed by immunohistofluorescence. Atrial natriuretic factor (ANF) and beta-myocin heavy chain ({beta}-MHC) were detected by reverse transcriptase polymerase chain reaction (RT-PCR). hPDMSCs treated with dan-shen root gradually formed a stick-like morphology and connected with adjoining cells. On the 20th day, most of the induced cells stained positive with {alpha}-sarcomeric actin and TnI antibody. ANF and {beta}-MHC were also detected in the induced cells. Approximately 80% of the cells were successfully transdifferentiated into cardiomyocytes. In conclusion, dan-shen root is a good inducer agent used for cardiomyogenic differentiation of hPDMSCs.

    Persicae Ramulus decoction, as the first prescription in Treatise on febrile Diseases, has been recommended by physicians of successive generations. It is also the general prescription for harmonizing yingfen and weifen, yin and yang, qi and blood. Although it only consists of five herbal medicines, it has a wider range of application and more categorized formulas than other prescriptions. Though Persicae Ramulus decoction was originally formulated to treat taiyang apoplexy, it has functions beyond the treatment of exopathic diseases. This formula is also effective in treating internal diseases, surgical diseases, gynecologic diseases, paediatric diseases, etc. KE Yun-bo praised it as the No. 1 formula among ZHANG Zhong-jin's formulas as well as the general prescription for harmonizing Yin and Yang, yingfen and weifen, resolving fleshy exterior and inducing perspiration. Professor SHI Xin-de has been expert at treating intractable diseases by using Persicae Ramulus-associated prescriptions, such as Xiaojianzhong decoction and Baohe pill for children's chronic eczema, Persicae Ramulus and Puerariae Lobatae Radix decoction and Yupingfeng powder for chronic nephritis, and Persicae Ramulus and Longgu Muli decoction for insomnia. Instead of being restricted to Chinese or Western disease names, he prescribed appropriate formulas according to syndromes, thereby achieving a good efficacy.

    This paper presents a modal, time-domain scheme for the nonlinear vibrations of perfect and imperfect plates. The scheme can take into account a large number of degrees-of-freedom and is energy-conserving. The targeted application is the sound synthesis of cymbals and gong-like musical instruments, which are known for displaying a strongly nonlinear vibrating behaviour. This behaviour is typical of a wave turbulence regime, in which the wide-band spectrum of excited modes is observable in the form of an energy cascade. The modal method is selected for its versatility in handling complex damping laws that can be implemented easily by selecting appropriate damping values in each one of the modal equations. In the first part of the paper, the modal method is explained in its generality, and it will be seen that the method is valid for plates with arbitrary geometry and boundary conditions as long as the eigenmodes are known. Secondly, a time-integration, energy-conserving scheme for perfect and imperfect plates is presented, and implementation comments are given in order to treat efficiently the high-dimensionality of the resulting dynamical system. The scheme is run with appropriate parameters in order to produce sound samples. A simple impact law is considered for the excitation, whereas the flexibility of the method is highlighted by showing simulations for free-edge circular plates and simply-supported rectangular plates, together with various damping laws.

    Background. Shen-Fu injection (SFI) following cardiac arrest exhibits neurological effects, but its effect on neurological dysfunction is unclear. This study sought to investigate the protective effect of SFI on nerve cells in a porcine model of cardiac arrest. Methods. After eight minutes of untreated ventricular fibrillation (VF) and 2 minutes of basic life support, 24 pigs were randomized and divided into three cardiopulmonary resuscitation groups, which received central venous injection of either Shen-Fu (SFI group; 1.0 ml/kg), epinephrine (EP group; 0.02 mg/kg), or saline (SA group). Surviving pigs were sacrificed at 24 h after ROSC and brains were removed for analysis for morphologic changes of mitochondria by electron microscopy, for mitochondrial transmembrane potential (MTP) by flow cytometry, and for opening of the mitochondrial permeability transition pore (MPTP) by mitochondrial light scattering. Results. Compared with the EP and SA groups, SFI treatment reduced opening of MPTP, showing higher MMP. In addition, animals treated with SFI showed slight cerebral ultrastructure damage under the electron microscopy. Conclusion. Shen-Fu injection alleviated brain injury, improved neurological ultrastructure, stabilized membrane potential, and inhibited opening of MPTP. Therefore, SFI could significantly attenuate postresuscitation cerebral ischemia and reperfusion injury by modulating mitochondrial dysfunction of nerve cells. PMID:25505924

    The structure solution of the modulated, delafossite-related, orthorhombic Ga3-xIn3TixO9+x/2 for x = 1.5 is reported here in conjunction with a model describing the modulation as a function of x for the entire system. Previously reported structures in the related A3-xIn3TixO9+x/2 (A = Al, Cr, or Fe) systems use X-ray diffraction to determine that the anion lattice is the source of modulation. Neutron diffraction, with its enhanced sensitivity to light atoms, offers a route to solving the modulation and is used here, in combination with precession electron diffraction tomography (PEDT), to solve the structure of Ga1.5In3Ti1.5O9.75. We construct a model that describes the anion modulation through the formation of rutile chevrons as a function of x. This model accommodates the orthorhombic phase (1.5 ≤ x ≤ 2.1) in the Ga3-xIn3TixO9+x/2 system, which transitions to a biphasic mixture (2.2 ≤ x ≤ 2.3) with a monoclinic, delafossite-related phase (2.4 ≤ x ≤ 2.5). The optical band gaps of this system are determined, and are stable at ∼3.4 eV before a ∼0.4 eV decrease between x = 1.9 and 2.0. After this decrease, stability resumes at ∼3.0 eV. Resistance to oxidation and reduction is also presented.

    Objective: To investigate the immunomodulating mechanisms of a Chinese herbal medicine Yi Shen Juan Bi (YJB) in treatment of adjuvant arthritis (AA) in rats. Materials and Methods: Levels of serum tumor necrosis factor alpha (TNF-α) and interleukin-1β (IL-1β) were measured by the Enzyme-Linked Immunosorbent Assay (ELISA). Expression of TNF-α mRNA and IL-1β mRNA in synovial cells was measured with the semi-quantitative technique of reverse transcription-polymerase chain reaction (RT-PCR), while caspase-3 was examined by western blot analysis. Results: The administration of YJB significantly decreased the production of serum TNF-α and IL-1β. It also decreased significantly the TNF-α mRNA, IL-1β mRNA, and caspase-3 expression in synoviocytes. Conclusions: YJB produces the immunomodulatory effects by downregulating the over-activated cytokines, while it activates caspase-3, which is the key executioner of apoptosis in the immune system. This may be the one of the underlying mechanisms that explains how YJB treats the rheumatoid arthritis. PMID:20711367

    Ramp-wave compression (RWC) experiment to balance the high compression pressure generation in aluminum and x-ray blanking effect in transparent window was demonstrated on Shen Guang-III prototype laser facility. A new target concept was proposed to develop a laser-driven shocks-RWC technique for studying material behavior under dynamic, high pressure conditions. As the ``little shocks'' in our experiment cannot be avoided, the effort to diminish the shock under a special level has been demonstrated with Al/Au/Al/LiF target. The highest pressure is about 500GPa after using the multilayer target design Al/Au/Al/LiF and about 1013W/cm2 laser pulse incident on the planer Al target, instantaneously affecting ablation layer located 500 μm away. As the x-ray generated by Al layer had been prevented by the Au layer, the width abrupt onset of strong absorption of an optical probe beam (λ = 532 nm) in LiF window may be the limitation for this kind if RWC experiment during the experiment time scale for 30 μm thick step. With the design laser shape and target structure of Al/Au/Al/LiF, 500GPa may be the highest pressure after balance the preheat effect and ablation efficiency for laser direct-drive experiment.

    A sensitive and reliable ultra high performance liquid chromatography coupled with quadrupole-time-of-flight mass spectrometry method was established to separate and identify the chemical constituents of Kai-Xin-San prescription, a classic traditional Chinese medicine formula that plays an important role in the treatment of Alzheimer's disease. The detection was performed on an Agilent 6520 Accurate-Mass quadrupole time-of-flight mass spectrometer equipped with an electrospray ionization source in negative modes. With the optimized conditions, a total of 54 compounds were identified or tentatively characterized. Out of the 54 compounds, six compounds were identified by comparing the retention time and mass spectrometry data with reference standards, the rest were characterized by analyzing mass spectrometry data and retrieving the literature data. Results indicated ginsenosides, polygala saponins, terpenoids, and oligosaccharide esters were the major effective constituents in Kai-Xin-San prescription. There were 26 prototype ingredients that were assigned for identification in rat plasma. It is also concluded that the developed ultra high performance liquid chromatography coupled with quadrupole-time-of-flight mass spectrometry method with high sensitivity and resolution is suitable for identifying and characterizing the chemical constituents of Kai-Xin-San prescription, and the analysis provides a helpful chemical basis for further research on Kai-Xin-San prescription and the clinical diagnostics of Alzheimer's disease.

    The upper reach of the Hutuo River flows along the Xin-Ding basin and cuts a transverse drainage through the Xizhou Mountain and the Taihang Range into the North China Plain. Previous studies showed that the Xin-Ding basin was occupied by a lake during the early-middle Pleistocene. However, the timing of the paleolake breach and the mechanism for the creation of the transverse drainage are unknown. We constructed the fluvial terrace sequence in the upper reach of the Hutuo drainage combined with thermoluminescence (TL) and optically stimulated luminescence (OSL) dating, as well as the timescale of the overlying loess-paleosol sequence. Our results reveal that (1) five terraces (T5-T1) developed along the upper reach of the Hutuo River, amongst which terraces T4-T1 were formed synchronously at ~ 600, ~ 120-130, ~ 20-26 and ~ 6-7 ka, respectively; (2) the creation of the transverse drainage and breach of the Xin-Ding paleolake occurred between ~ 600 and ~ 130 ka; and (3) the mechanism for the creation of the transverse drainage is via river piracy of paleostreams on both sides of the drainage divide. Localized differential uplift and associated tilting of the Xizhou Mountain block during the middle Pleistocene result in the formation of the transverse drainage and breach of the Xin-Ding paleolake.

    Novel materials for the infrared two-photon absorption — Tl1-xIn1-xSnxSe2 single crystals (x = 0.1,0.2) were grown. Two-photon absorption (TPA) was studied at CO2 laser wave-length 9.4μm with pulse duration 1μs. The studies were performed at different temperatures and for the nanocrystallite sizes varying within the 7-200 nm. The studies have shown that the TPA may be enhanced during the decrease of the nanocrystallite sizes below 50-60 nm. There exists also some critical x value at which the TPA value begin substantially to increase. The studied nanocrystallites are relatively stable to the infrared laser treatment and are not hygroscopic which allow to use them in different IR optoelectronic devices.

    A novel low temperature hydrothermal synthesis of II-III2-VI4 (II = Zn, Cd; III = In; VI = S) mixed ternary chalcogenide semiconductors as visible photocatalysts for solar hydrogen production was performed. In this work, an X-ray diffraction based structural and microstructural study of chalcogenide semiconductors type CdxZn1-xIn2S4 (0 ≤ x ≤ 1) is reported. The investigated powder samples were synthesized by a hydrothermal technique, using a Teflon lined closed autoclave with self-generated pressure, at 180°C for 20 hours. Rietveld method based on pseudo-Voigt profile fitting function was applied to perform a simultaneous refinement of X-ray diffraction patterns concerning both material structure and microstructure. The Rietveld refinement of the X-ray diffraction data has been done using the MATCH, MAUD and PowderCel softwares.

    The Leqingla and Xin'gaguo deposits are two representative skarn Pb-Zn polymetallic deposits of the Gangdese Pb-Zn polymetallic belt, Tibet, China. LA-ICP-MS zircon U-Pb dating of the mineralization-related biotite granites from both the Leqingla and Xin'gaguo deposits yielded weighted mean ages of 60.8 Ma and 56.5 Ma, respectively, which can be inferred as their mineralization ages. The Leqingla biotite granite is characterized by high Al2O3, total Fe, Na2O, and low K2O. In comparison, the Xin'gaguo biotite granite is characterized by relative higher K2O but lower Al2O3, total Fe, and Na2O. Geochemical and mineralogical characteristics indicate that the Leqingla and Xin'gaguo biotite granites are calc-alkaline I-type granite and High K calc-alkaline I-type granite, respectively. Both the Leqingla and Xin'gaguo biotite granites are enrichment in LREE and LILEs and depletion in HFSEs, and they were formed at the India-Asia collision stage. δ18O and δD values for the Leqingla and Xin'gaguo deposits are -8.8‰ to 5.3‰ and -140.4‰ to -90.1‰, -4.5‰ to 7.0‰ and -117.3‰ to -81.0‰, respectively, indicating magma fluids mixed with meteoric water in ore-forming fluids. δ34S values (-11.6‰ to -0.3‰) of ore sulfides from the Leqingla deposit show characteristics of biogenetic sulfur isotope compositions, suggesting sulfur for the Leqingla deposit were sourced from wall rocks of the Mengla and Luobadui Formation, which are rich in organic materials. δ34S values of ore sulfides from the Xin'gaguo deposits show bimodal distribution (-5.0‰ to -1.6‰ and 1.6-2.1‰), indicating sulfur in the Xin'gaguo deposit were derived from both wall rocks and magma. In the Leqingla deposit, most ore sulfides have the similar Pb isotopic compositions with that of the mineralization-related biotite granite, suggesting the biotite granite supplied most of the ore-forming metals. Pb isotopic compositions of ore sulfides and Hf isotopic compositions of biotite granite show

    Chronic kidney disease (CKD) is becoming a worldwide problem. However, current treatment options are limited. In the current study we showed that QiShenYiQi (QSYQ), a water-ethanol extract from several Chinese medicines, is a potent inhibitor of renal interstitial fibrosis. QSYQ inhibited transforming growth factor-β1 (TGF-β1)-responsive α-smooth muscle actin (α-SMA), collagen I, and fibronectin up-regulation in obstructive nephropathy and cultured cells. Administration of QSYQ also inhibited the established renal interstitial fibrosis in obstructive nephropathy. Interestingly, QSYQ selectively inhibited TGF-β1-induced β-catenin up-regulation and downstream gene transcription. Taken together, our study suggests that QSYQ selectively inhibits TGF-β1-induced β-catenin up-regulation and might have significant therapeutic potential for the treatment of renal fibrosis.

    Endothelial dysfunction, which is caused by endothelial nitric oxide synthase (eNOS) uncoupling, is an initial step in atherosclerosis. This study was designed to explore whether Chinese medicine xin-mai-jia (XMJ) recouples eNOS to exert anti-atherosclerotic effects. Pretreatment of XMJ (25, 50, 100 μg/ml) for 30 minutes concentration-dependently activated eNOS, improved cell viabilities, increased NO generations, and reduced ROS productions in human umbilical vein endothelial cells incubated with H2O2 for 2 hours, accompanied with restoration of BH4. Importantly, these protective effects produced by XMJ were abolished by eNOS inhibitor L-NAME or specific eNOS siRNA in H2O2-treated cells. In ex vivo experiments, exposure of isolated aortic rings from rats to H2O2 for 6 hours dramatically impaired acetylcholine-induced vasorelaxation, reduced NO levels and increased ROS productions, which were ablated by XMJ in concentration-dependent manner. In vivo analysis indicated that administration of XMJ (0.6, 2.0, 6.0 g/kg/d) for 12 weeks remarkably recoupled eNOS and reduced the size of carotid atherosclerotic plaque in rats feeding with high fat diet plus balloon injury. In conclusion, XMJ recouples eNOS to prevent the growth of atherosclerosis in rats. Clinically, XMJ is potentially considered as a medicine to treat patients with atherosclerosis.

    The theoretical investigation has been carried out on the binding energy of donor associated with the electrons confined in a Cd1 -xinMnxin Te /Cd1 -xoutMnxout Te Double Quantum Well (DQW) as a function of central barrier width for various well dimensions and impurity locations in the barrier and the well. The magnetic field can act as a tool to continuously change the interwell coupling inside this DQW systems and its effect on donor binding has also been studied. Moreover, the polaronic corrections, which is due to the strong exchange interaction between the magnetic moment of Mn2+ ion and the spin of the confined carrier, to the binding energy of the hydrogenic donor impurity has also been estimated with and without the application of magnetic field. The binding energy of the donor impurity is determined by solving the Schrodinger equation variationally in the effective mass approximation and the effect due to Bound Magnetic Polaron (BMP) is included using mean field theory with the modified Brillouin function. The results are reported and discussed.

    The present study aimed to evaluate the effect of kai xin san (KXS, at doses of 500, 250, and 125 mg/kg body weight per day), a well-known traditional Chinese medicine, on learning and memory in paradoxical sleep deprivation (PSD)-induced cognition deficit rats. Two behavior tests (the Open Field test and the Morris water maze task) were used for testing the effects of KXS on a PSD-induced learning and memory deficit model. Furthermore, its effect on the glutamic acid (GLU) and γ-amino-butyric acid (GABA) levels in the brain tissue, brain-derived neurotrophic factor (BDNF), cyclic AMP response element binding protein (CREB), and phosphorylated-CREB (p-CREB) expression in the hippocampus was also tested. KXS exerted the greatest cognition against the 48 h PSD-induced cognitive deficit and these effects may be mediated by decreasing the GLU and GABA levels and increasing the levels of BDNF, CREB, and p-CREB. This study indicates that the effect of KXS on learning and memory in a rat model of PSD could be associated with the modulation of neurotransmitter levels and the expression of some genes in the brain that contribute to memory functions.

    In the last decade, Portugal was affected by a number of windstorms associated with mid-latitude cyclones, some with significant impact on built infrastructures, namely on the electric grid. Two of those storms were particularly violent, the Oeste storm on the 23 December 2009, and the Gong storm on 19 January 2013. The Klaus storm, on the 23 January 2009, had some impact but only in the northern edge of Iberia, but the Xinthia storm, on the 27 February 2010, had extensive impact in the Portuguese territory. Considering impacts on the electric grid, these 4 storms are part of a set of about 10 storms per decade, although earlier storms didn't get a name. The relevance of these extreme events in recent climate motivated a case study analysis of the more relevant storms and its analysis in a continuous regional climate simulation of the Iberian climate. The RCM simulation used WRF at 9km resolution, with ERA-Interim boundary conditions initially for the period 1989-2008, here extended until 28 Feb 2013. The former simulations were extensively validated against Iberian gridded temperature and precipitation datasets (Soares et al 2012), and against Portuguese station data (Cardoso et al 2013). Results are here validated, in the extended 24 year period, also against standard 10-m wind observations. Case study analysis used the same boundary conditions and model (WRF), but at both 9 and 3 km horizontal resolutions, and also included sensitivity experiments to different parametrizations. While the WRF RCM simulation, forced by ERA-Interim, presents an overall excellent performance in the representation of both the mean climate (temperature, precipitation and wind), and also in the representation of high-rank precipitation quantiles, the two most extreme windstorm events are not well represented. However, the Gong storm is very well represented in the case study simulation, even at 9km resolution with exactly the same boundary conditions, but a somewhat different initial

    In order to research the infrared radiation characteristics of the skin covering Traditional Chinese acupuncture points, which are NeiGuan in the forearm and LaoGong in the center of the palm, we detected continuously the infrared radiation spectra of the human body surface by using Fourier Transform Infrared Spectroscopy. The experimental results showed that firstly, the differences of the infrared radiation spectra of the human body surface were obvious between individuals. Secondly, the infrared radiation intensity of the human body surface changed with time changing. The infrared radiation intensity in two special wavelength ranges (wavelengths from 6. 79 microm to 6. 85 microm and from 13. 6 microm to 14. 0 microm) changed much more than that in other ranges obviously. Thirdly, the proportions of the infrared radiation spectra changed, which were calculated from the spectra of two different aupuncture points, were same in these two special wavelength ranges, but their magnitude changes were different. These results suggested that the infrared radiation of acupuncture points have the same biological basis, and the mechanism of the infrared radiation in these two special wavelength ranges is different from other tissue heat radiation.

    San-Huang-Xie-Xin-Tang (SHXXT), one of the most important traditional Chinese medicinal formulas, is comprised by three herbal medicines, the rhizome of Rheum officinale [or Rheum tanguticum (Polygonaceae) (Dahuang in Chinese)], the root of Scutellaria baicalensis (Labiatae) (Huangqin in Chinese), and the rhizome of Coptis chinensis (Ranunculaceae) (Huanglian in Chinese) in the ratios of 2:1:1 or 1:1:1. This study is aimed to quantitate and qualify of SHXXT, by a rapid, convenient, and effective HPLC-PDA approach associated with LC-MS technique. Of which method, nine chosen major bioactive components in SHXXT, including aloe-emodin (Ale), baicalin (Ba), berberine (Be), coptisine (Co), palmatine (Pa), resveratroloside (Res), rhein (Rh), sennoside A (Se-A), and wogonin (Wo), were evaluated within 30 min. The nine chemical markers were monitored in a high sensitivity with a low detection limit of 0.01−0.55 μg/mL and the correlation coefficient of the regression curve revealed a good linearity with R2 > 0.99. Moreover, the extraction solution system and the HPLC elution conditions were also optimized in the present study. This present developed protocol was then successfully applied to quantify nine chemical markers of 10 SHXXT products from eight Taiwanese TCM pharmaceutical companies. In quantitative results, Res was found as the major compound in SHXXT-1~5 and 8 with significantly higher amounts than those in other products, indicating the products SHXXT-1~5 and 8 may use R. tanguticum as the raw material, which possessed a higher concentration of the bioactive composition Res, instead of R. officinale. Simultaneously, Ale, Rh, and Wo were < 2% in these 10 products. Different chemical profiles of commercial products indicated that, probably, each product with the same named formula might be regarded as a sole medicine and need to be investigated individually. Importantly, it is never too much to emphasize the importance of quality control in TCM development. PMID

In this study, the Soil and Water Assessment Tool (SWAT) and Statistical Downscaling Method (SDSM) were integrated and applied to estimate streamflows in the Xin River Basin, China, based on climate change scenarios downscaled from different GCMs (BCC-CSM1.1, CanESM2, and NorESM1-M) under three Representative Concentration Pathways (RCPs). Results confirmed that the calibrated SWAT model accurately depicts hydrological processes features at daily, monthly, and yearly scales. Three GCMs based on the calibrated SDSM showed that temperature is continually increasing in the region, however, future precipitation is highly complex and uncertain; there were significant differences among various GCM RCP scenarios. The average of the precipitation in three models showed slight and steady increase trends under RCP2.6 and RCP4.5, but a significant increase under the RCP8.5 scenario. The ensemble average of streamflow in GCMs demonstrated that many RCPs significantly decrease from May to June but increase from August to September relative to the baseline period. The ensemble mean of the multi-GCM indicated that future streamflows under RCP2.6 and RCP4.5 scenarios will be closer to the current streamflow volume. Many RCPs also revealed a significant increase in monthly streamflow dispersion coefficient in October, reflecting a tendency for drought and flood events in that month. The BCC-CSM1.1 and NorESM1-M models showed that streamflows are higher than the baseline with median probability in the future. The low monthly streamflow (10th percentile) processes for each GCM were altogether similar to the baseline, whereas the high monthly streamflows (90th percentile) showed various levels of disparity compared to the baseline.

    Androgens have been linked to the onset, severity, and progression of rheumatoid arthritis (RA). In traditional Chinese medicine (TCM), the most common pattern in RA is kidney deficiency, which partly corresponds to a low sex hormone state. In this study, TCM kidney deficiency was induced in male Sprague-Dawley rats with castration surgery, and a TCM preparation, Yi Shen Juan Bi Pill (YJB), was used to treat collagen induced arthritis (CIA) rats with castration. Metabolomic technique was used to evaluate the pharmacological mechanism in castrated CIA rats treated by YJB. The results showed that castration significantly increased the severity of the arthritis in rats but was ameliorated by YJB. Its pharmacological mechanism was partially associated with lipid metabolites involving free fatty acid (FFA) and lysophosphatidylcholine (LPC). In conclusion, the experimental results demonstrate the protective effect of YJB on the TCM kidney deficiency pattern induced by androgen deficiency in CIA rats and support that YJB should be used for the clinical treatment of RA with TCM kidney deficiency pattern.

    Background. Several types of drugs have been recommended for the secondary prevention of myocardial infarction (MI). However, these conventional strategies have several limitations, such as low adherence, high cost, and side effects during long time use. Novel approaches to this problem are still needed. This trial aimed to test the effectiveness and safety of Qi-Shen-Yi-Qi Dripping Pills (QSYQ), a multi-ingredient Chinese patent medicine, for the secondary prevention of MI. Methods and Findings. A total of 3505 eligible patients were randomly assigned to QSYQ group (1746 patients) or aspirin group (1759). Patients took their treatments for 12 months. The final follow-up visit took place 6 months after the end of the trial drugs. The 12-month and 18-month estimated incidences of the primary outcome were 2.98% and 3.67%, respectively, in the QSYQ group. The figures were 2.96% and 3.81% in the aspirin group. No significant difference was identified between the groups. Conclusions. This trial did not show significant difference of primary and secondary outcomes between aspirin and QSYQ in patients who have had an MI. Though inconclusive, the result suggests that QSYQ has similar effects to aspirin in the secondary prevention of MI. PMID:23935677

    A model of phosphorus purification in a watershed was established based on the export coefficient and purification index of phosphorus in different types of land cover. The model was employed to simulate the economic value of the ecosystem service with the expected water quality standard and marginal cost of pollutant purification of the upper reaches of Xin' an River of Anhui, China. The results revealed that from 2000 to 2010, some farmland outside the Tunxi, Jixi, Shexian, Yixian and Xiuning was converted to built-up land. The total amount of phosphorus exported to the upper Xin' an River decreased a little, and the main source of phosphorus pollution was farmland and built-up land. More than half of the exported phosphorus was efficiently purified by different types of land cover via flow accumulation. The pattern of purification and export of highly concentrated phosphorus showed the same trend which occurred in the northern part of the watershed including the Yangzhi River, Fengle River and Hengjiang River. Forestland and grassland did not efficiently purify phosphorus in the watershed owing to the irrational distribution of existing land cover. The total service value was 3.80 and 3.31 million Yuan in 2000 and 2010, respectively.

    Several Ga 1-xIn xSb layers, capped with 1 μm of GaSb, were grown on GaSb(0 0 1) substrates by molecular beam epitaxy in a Varian Gen II Modular system using either the conventional sample growth position with substrate rotation, or a tilted sample position with no substrate rotation. The GaInSb layers were examined by X-ray diffraction (XRD) using both symmetrical and asymmetrical reflections. The "tilted sample method" gave a variation of ±25% in thickness of the Ga 1-xIn xSb layers, while the indium (In) content varied by ±10% around the nominal value. The disappearance of thickness fringes in 004 XRD scans was used to determine the onset of relaxation, as determining the in-plane lattice constant for tilted samples was found to be difficult. Determining residual strain in samples grown by the tilted method was likewise found to be very difficult. The critical thickness for several In mole fractions between 5% and 19% was determined and was found to be from 2.2 to 2.7 times higher than predicted by Matthews and Blakeslee (1974) [J. Crystal Growth 27 (1974) 118] but lower than that predicted by People and Bean (1985) [Appl. Phys. Lett. 47 (1985) 322].

    The crystal structure of Li2-xAg1+xIn3 (x=0.05) has been determined on a single crystal synthesized from the elements in a tantalum crucible. The compound crystallizes in orthorhombic space group Pmma (a=9.325 (3) Å, b=3.198 (1) Å, c=8.043 (3) Å at 296 K) with 12 atoms per unit cell and represents a new structure type. The structure of Li2-xAg1+xIn3 is closely related to the LaCoAl4 structure and belongs to the structural family, the representative members of which may be derived from the hexagonal AlB2 structure type by a combination of internal deformation and substitution. The strong In-In interaction and close to zero electrons concentration around Li and Ag atoms, calculated by LTMO, allow to suggest high mobility of lithium atoms located within the channels formed by the strongly waved [-In-In-] polyanionic chains.

    This study analyzed cored sediments retrieved from sites distributed across a transect of the Lei-Gong-Hou mud volcanoes in eastern Taiwan to uncover the spatial distributions of biogeochemical processes and community assemblages involved in methane cycling. The profiles of methane concentration and carbon isotopic composition revealed various orders of the predominance of specific methane-related metabolisms along depth. At a site proximal to the bubbling pool, the methanogenic zone was sandwiched by the anaerobic methanotrophic zones. For two sites distributed toward the topographic depression, the methanogenic zone overlaid the anaerobic methanotrophic zone. The predominance of anaerobic methanotrophy at specific depth intervals is supported by the enhanced copy numbers of the ANME-2a 16S rRNA gene and coincides with high dissolved Fe/Mn concentrations and copy numbers of the Desulfuromonas/Pelobacter 16S rRNA gene. Assemblages of 16S rRNA and mcrA genes revealed that methanogenesis was mediated by Methanococcoides and Methanosarcina. pmoA genes and a few 16S rRNA genes related to aerobic methanotrophs were detected in limited numbers of subsurface samples. While dissolved Fe/Mn signifies the presence of anaerobic metabolisms near the surface, the correlations between geochemical characteristics and gene abundances, and the absence of aerobic methanotrophs in top sediments suggest that anaerobic methanotrophy is potentially dependent on iron/manganese reduction and dominates over aerobic methanotrophy for the removal of methane produced in situ or from a deep source. Near-surface methanogenesis contributes to the methane emissions from mud platform. The alternating arrangements of methanogenic and methanotrophic zones at different sites suggest that the interactions between mud deposition, evaporation, oxidation and fluid transport modulate the assemblages of microbial communities and methane cycling in different compartments of terrestrial mud volcanoes.

    Abstract Objectives: This open-label, prospective, phase I/II trial was performed to establish the safety and efficacy of Traditional Chinese Medicine (TCM) herbal products for treating non–anemia-related fatigue in patients with cancer. Although this practice is widespread in China, it has not been confirmed in a prospective clinical study. Design: Thirty-three patients who had completed cancer treatment, had stable disease and no anemia, and reported moderate to severe fatigue (rated ≥4 on a 0–10 scale) were enrolled in a TCM outpatient clinic. Patients took Ren Shen Yangrong Tang (RSYRT) decoction, a soup containing 12 TCM herbs, twice a day for 6 weeks. RSYRT aims to correct qi deficiency. Fatigue was assessed before and after RSYRT therapy, which all patients completed. Results: No discomfort or toxicity was observed. Before the study, all patients had had fatigue for at least 4 months. Fatigue severity decreased significantly from before therapy to 6 weeks after therapy: from 7.06 to 3.30 on a 0–10 scale (p<0.001). Fatigue category (mild, moderate, severe) shifted significantly (p=0.024): Of 22 patients with severe fatigue (rated ≥7) before therapy, 11 had mild fatigue and 11 had moderate fatigue after TCM treatment. The time-to-fatigue-alleviation was 2–3 weeks. Conclusion: RSYRT therapy was safe and was associated with fatigue improvement in nonanemic cancer survivors, consistent with historical TCM clinical practice experience. Because of a possible placebo effect in this open-label study, decoction RSYRT warrants further study in randomized clinical trials to confirm its effectiveness for managing moderate to severe fatigue.

The objective of this study was to assess the effect of SMD-2 on the levels of urinary copper (Cu), zinc (Zn), and selenium (Se) in lung cancer patients and head and neck cancer patients receiving chemoradiotherapy. Forty-two head and neck cancer patients and 10 lung cancer patients participated in our clinical trial. Each patient received chemoradiotherapy for 4 weeks. In addition, each patient was treated with SMD-2 for 8 weeks, including 2 weeks prior to and after the chemoradiotherapy treatment. Comparison of urinary Cu, Zn, and Se levels and the ratios of Zn to Cu and Se to Cu at three time points in the two types of cancer were assessed using the generalized estimating equations (GEEs). After the patients received chemoradiotherapy for 4 weeks, SMD-2 treatment was found to be associated with a significant decrease in urinary Cu levels, whereas urinary Zn and Se levels increased significantly. In addition, the ratios of Zn to Cu and Se to Cu in the urine samples of these patients also increased significantly. Both the urinary Zn levels and the ratio of Zn to Cu in head and neck cancer patients were significantly higher than in lung cancer patients. Urinary Zn and Se levels and the ratios of Zn to Cu and Se to Cu, but not urinary Cu levels, increased significantly during and after treatment when assessed using the GEE model. The SMD-2 treatments significantly increased Zn and Se levels in the urine of head and neck cancer patients. Increased Zn and Se levels in urine strengthened immune system. PMID:27114935

    The aim of the present work is to complete a preliminary study concerning the electronic band structure investigations of NaxCu1-xIn5S8 compounds with 0≤x≤1 , which are expected to be formed at the Cu(In,Ga)Se2/In2S3 interface. The band structure calculations demonstrate that for the compounds containing both Na and Cu, as the Cu content increases the band gap tends to decrease, and x-ray photoemission spectroscopy measurements show that this variation is mainly due to valence-band-maximum shift along the solid solution. The band gap strongly depends on the nature of the monovalent cation, and the band structure calculations demonstrate that the d electrons of copper are responsible for the shift of the valence band. In addition, it is worth noting that the Cu-containing compounds have indirect gaps.

    Valence band structure of GaAs/Ga xIn 1-xP strained-layer quantum wells are investigated within an envelope function formalism which takes into account the valence subbands mixing through the Luttinger-Kohn Hamiltonian and the strain effects due to the lattice-mismatch through the Pikus-Bir Hamiltonian. For a Ga mole fraction x greater than 0.516 (compression), the top valence band is heavy-hole-like. For x less than 0.516 (tension strain), the top valence subband can be either heavy-hole-like or light-hole-like, depending on the well width and on the shear deformation potential. Interesting features are also obtained for the effective masses of the valence subbands from ɛ( K→) energy dispersion calculations along the in-plane K→ direction.

    Effect of the long-term treatment with a Dan-Shen (Salviae miltiorrhizae radix) methanol extract (DME) or its major ingredient lithospermate B (LSB) on memory and learning in scenescence-accelerated mouse (SAM) was investigated by means of Morris's water maze task. DME or LSB treatment significantly decreased the escape latency in the P8 strain of SAM (SAMP8), which strain spontaneously develops learning deficits. These results suggest that DME and LSB treatment improved spacial learning. Neurochemical investigations indicated that both drugs did not affect the cholinergic system, but enhanced functions of the glutamate-PKC system in hippocampus, since the increases in [3H]MK-801 ((+)-5-methyl-10,11-dihydro-5H-dibenzo[a,b]-cyclohepten-5,10-imine maleate) binding in cortex and [3H]PDBu (phorbol 12,13-dibutyrate) binding in hippocampus were observed in DME and LSB treatments. Our previous studies indicate the decrease in PDBu binding and NMDA receptor-mediated functions in SAMP8 brain. Thus, it is suggested that 1) Methanol extract of Dan-Shen is effective for prevention of spacial learning deficit caused with aging, 2) lithospermate B is one of the active ingredients, 3) SAMP8 is useful model animal to investigate drugs for anti-aging or anti-dementia.

    Non-point source (NPS) pollution has been recognized as the largest threat to water resources throughout the world, and the evaluation of NPS loads is a priority. In China, some models, such as SWAT (Soil and Water Assessment Tools) model, have been widely used at the watershed scale. However, variations in natural and social factors make it difficult to find a proper model to use on NPS pollution management in China. In this study, a "Dualistic Structure" model is coupled with remote sensing data to capture the spatial and temporal processes of NPS pollution. Land parameters were derived from HJ-1A and HJ-1B satellite data (resolution 30 m), which offered greatly enhanced spatial resolution. This approach offers the advantage of being a rapid estimation system with fairly precise knowledge of the distribution, sources and quantities of NPS pollutants, and it can be used at the country scale, including in areas with insufficient data. The method is used in the Xin'anjiang catchment, an important water source for Hangzhou city, China. The simulation in this study includes the spatial distribution of monthly total nitrogen (TN), total phosphorous (TP), ammonia nitrogen (NH(4)-N) and chemical oxygen demand (COD(cr)) loads and the total production of NPS pollutants. The simulations were compared to pollution census (PC) data in 2010 and the results of SWAT model, with an average R(2) larger than 0.7. Additionally, the impacts of soil erosion and human activities on NPS pollution were assessed, indicating that soil and water conservation is very significant factor in the Xin'anjiang catchment. Results indicate that by coupling remote sensing data and parameter retrieval techniques to "Dualistic Structure" models, estimations of NPS loads on the catchment scale can be improved by spatial pixel-based modeling. This rapid NPS estimation system will offer effective support to policy makers for environmental management in China.

    We appreciate Willem J. Zaadnoordijk's comments, which led us to revisit the results in Xin et al. (2016). Zaadnoordijk (2016) solved numerically the Boussinesq equation-based (BE) model, Eq. (6) in Xin et al. (2016), and found that (1) the transient groundwater tables predicted by the numerical BE model didn't match Fig. 5b in Xin et al. (2016) and (2) with an adjusted effective specific yield (discussed further below), the BE model predicted similar results to the analytical solution that accounts for the unsaturated zone effects. We address these two points in the following. (1) The results of Fig. 5b in Xin et al. (2016) were calculated from the analytical solution with the unsaturated zone neglected. Although the governing equation of the saturated-unsaturated mathematical model presented in Xin et al. (2016) can be reduced to the Boussinesq equation with the unsaturated zone neglected (i.e., α and β approaching infinity), the application of the approximate analytical solution directly to this limiting condition incurs large errors as contained in Fig. 5b of Xin et al. (2016). In this reply we derive a new analytical solution separately for the BE model (detailed derivation given in the appendix) with such errors removed.

    Background The concept of acupuncture point localisation in Traditional Chinese Medicine (TCM) is based on millenary practical experience. Modern imaging methods such as PET, MRI and SPECT have been used primary for the investigation of the mechanisms of action of acupuncture. In this pilot single-case study we have evaluated the technical possibilities for in-vivo imaging of the anatomical relations of acupuncture points using state of the art MRI. Methods Preliminary experiments relating to the quality of acupuncture needles under the setting of MRI were done both with stainless steel and gold needles. In a second step, in-vivo imaging was carried out. A licensed acupuncture practitioner (RM) chose two points belonging to the so-called extraordinary vessels. In 2 sequential, separate procedures, he inserted himself gold acupuncture needles using a neutral technique (known as Ping Bu Ping Xie) into the Dai mai and Shen mai points, i.e. gall bladder 26 and bladder 62. Imaging was done on a Siemens Magnetom Avanto MR scanner using a head array and body coil. Mainly T1-weighted imaging sequences, as routinely used for patient exams, were used to obtain multi-slice images. Results In the preliminary experiments only acupuncture needles made of gold showed enough stability in order to be used for further imaging procedures. Using an onion and a banana as an object, further studies showed that the gold needles produced a void defect that corresponds to the tip of the inserted needle, while at the same time an artefactually increased diameter was observed. The in-vivo experiments showed that the Dai mai point was in relation to the abdominal internal oblique muscle. The Shen mai point artefact showed up close to the longus and brevis peroneal tendons at the fibular malleolus. Side effects related to heating or burning were not observed. Improved anatomical recognition was obtained using 3D-volume rendering techniques. Conclusion Through an adequate choice of acupuncture

    San-Huang-Xie-Xin-Tang (SHXXT), a widely used Chinese herbal formula, consists of rhizomes of Rheum officinale, roots of Scutellaria baicalensis and rhizomes of Coptis chinesis. This study investigated the metabolism and pharmacokinetics of polyphenols in SHXXT, including baicalin, baicalein, wogonin, emodin, aloe-emodin, rhein and chrysophanol. The quantitation methods of SHXXT decoction and rat serum using high performance liquid chromatography were developed and validated in this study. After oral administration of SHXXT decoction to rats, the parent forms of various constituents and their conjugated metabolites in serum were determined before and after hydrolysis with β-glucuronidase and sulfatase. The results showed that only free form of rhein can be quantitated, whereas the parent forms of coptisine, palmatine, berberine, baicalein, wogonin, emodin, aloe-emodin and chrysophanol were not detected in serum. The glucuronides of baicalein, wogonin, emodin, aloe-emodin, rhein and chrysophanol were the predominant forms in bloodstream. In order to evaluate the in vivo antioxidant activity of SHXXT, the serum metabolite of SHXXT was prepared, characterized and followed by evaluation of the effect on AAPH-induced hemolysis. The results indicated that metabolites of SHXXT exhibited significant free radical scavenging activity. We suggest that biologists redirect their focus to the bioactivity of the conjugated metabolites of these polyphenols. PMID:19737807

    We examined the protective effects of ultrafiltered XinMaiJia (XMJ) extract in a hydrogen peroxide (H2O2)-induced injury model in human umbilical vein endothelial cells (HUVECs) and determined the corresponding changes in the Na(+)-H(+) exchanger (NHE1) protein content and NHE1 gene expression. H2O2-induced HUVECs were treated with different concentrations of XMJ extract and the corresponding changes in morphology, activity, membrane permeability, biochemical indicators, cytokine concentration, NHE1 protein content, and NHE1 gene expression were determined. H2O2 significantly promoted HUVEC injury, whereas ultrafiltered XMJ extract significantly improved the morphological changes in injured HUVECs, increased their activity, and decreased NHE1 gene and protein expression, as well as limited the decrease in membrane permeability and expression of intercellular adhesion molecule-1, vascular cell adhesion molecule-1, interleukin (IL)-1, IL-6, and nuclear factor-kB. Ultrafiltered XMJ extract inhibited H2O2-induced HUVEC injury by inhibiting NHE1 activity.

Our preliminary phylogenetic analyses indicated that these two strains share high sequence similarity and therefore showed strong potential to be united into a single species. To clarify the taxonomic status of the two species, a polyphasic taxonomy study was conducted including whole genome sequencing. The value of average nucleotide identity (ANI) and digital DNA-DNA hybridization (dDDH) between the genome sequences of S. flexibilis ATCC 29606(T) and P. tuomuerensis JCM 14085(T) were 98.1% and 89.0%, respectively. The phenotypic and chemotaxonomic properties including enzymatic activities, substrate utilization profiles, and fatty acids, supported that the two taxa have no pronounced difference and should thus constitute a single species. Therefore, we propose to transfer Serpens flexibilis Hespell 1977 to the genus Pseudomonas as Pseudomonas flexibilis comb. nov. (type strain=ATCC 29606(T)), with Pseudomonas tuomuerensis Xin et al. 2009 as a later heterotypic synonym of Pseudomonas flexibilis.

    Kai-Xin-San (KXS), a Chinese herbal decoction for anti-depression, is a combination of paired-herbs, i.e. Ginseng Radix et Rhizoma (GR)-Polygalae Radix (PR) and Acori Tatarinowii Rhizoma (ATR)-Poria (PO). The make-up of the paired-herbs has been commonly revised according to syndrome differentiation and treatment variation of individual. Currently, an optimized KXS (KXS2012) was prepared by functional screening different combination of GR-PR and ATR-PO. The aim of this study was to verify the effect and underlying mechanism of KXS2012 against depression in chronic mild stress (CMS)-induced depressive rats and in primary cultures of neurons and astrocytes. In rat model, the CMS-induced depressive symptoms were markedly alleviated by the treatment with KXS2012. The CMS-suppressed neurotransmitter amounts were restored in the presence of KXS2012. And the expressions of neurotropic factors and its corresponding receptors were increased under KXS2012 administration. In cultured neurons, application of KXS2012 could promote neurogenesis by inducing the expression of synaptotagmin and dendritic spine density. Moreover, application of KXS2012 in cultured astrocytes, or in H2O2-stressed astrocytes, induced the expressions of neurotrophic factors: the increase might be associated with the modification of Erk1/2 and CREB phosphorylation. Our current results fully support the therapeutic efficacy of KXS2012 against depression in cell and animal models. PMID:27444820

    Xin-Ke-Shu (XKS) is a traditional Chinese patent medicine used for treatment of coronary heart diseases in China. However, its mechanism of action is still unclear. In this paper, the mediation of XKS on the isoproterenol (ISO)-induced myocardial infarction (MI) rat were evaluated based on a tissue-targeted metabonomics in vitro/vivo. The result indicated that twelve metabolic pathways were involved in the therapeutic effect of XKS in vivo, where seven pathways were associated with the Ca2+ overloading mechanism. In agreement with regulation on metabolic variations, XKS markedly reversed the over-expressions of three involved proteins including phospholipase A2 IIA (PLA2 IIA), calcium/calmodulin-dependent protein kinase II (CaMK II) and Pro-Caspase-3. The metabolic regulations of XKS on H9c2 cell also partially confirmed its metabolic effect. These metabolic characteristics in vitro/vivo and western blotting analysis suggested that XKS protected from MI metabolic perturbation major via inhibition of Ca2+ overloading mechanism. Furthermore, 11 active ingredients of XKS exerted steady affinity with the three proteins through the molecular docking study. Our findings indicate that the metabonomics in vitro/vivo combined with western blotting analysis offers the opportunity to gain insight into the comprehensive efficacy of TCMs on the whole metabolic network.

    The aim of the present study was to explore whether an ultra-filtration extract from Xin Mai Jia (XMJ), a Chinese medicinal formulation, has a protective effect on human aortic smooth muscle cell (HASMC) injury models induced by hydrogen peroxide (H2O2), and to consider the mechanism and efficacy of the therapeutic action of XMJ on atherosclerosis. HASMCs were injured by H2O2 and then exposed to various concentrations of XMJ. The morphological changes, growth, proliferation, migration and cytokine release of HASMCs were detected using 2,3-bis-(2-methoxy-4-nitro-5-sulfophenyl)-2H-tetrazolium-5-carboxanilide (XTT), an enzyme-linked immunosorbent assay and a scratch adhesion test. H2O2 significantly promoted the proliferation of HASMCs. The ultra-filtration extract from XMJ was observed to significantly attenuate the morphological changes of injured HASMCs, reduce the expression levels of intercellular adhesion molecule-1 (ICAM-1), vascular cell adhesion molecule-1 (VCAM-1), interleukin (IL)-1, IL-6 and nuclear factor (NF)-κB, and increase the expression levels of matrix metalloproteinase (MMP)-2 and tissue inhibitor of metalloproteinase (TIMP). XMJ has clear anti-inflammatory and antioxidant effects, and significantly inhibits the proliferation and migration of HASMCs. PMID:24348756

    Inflammatory disorders underlie varieties of human diseases. San-Huang-Xie-xin-Tang (SHXXT), composed with Rhizoma Rhei (Rheum palmatum L.), Rhizoma Coptidis (Coptis chinensis Franch), and Radix Scutellaria (Scutellaria baicalensis Georgi), is a famous formula which has been widely used in the fight against inflammatory abnormalities. Mutual reinforcement is one of the basic theories of traditional Chinese medicine. Here this article reviewed and analyzed the recent research on (1) How the main constituents of SHXXT impact on inflammation-associated signaling pathway molecules. (2) The interaction between the main constituents and efflux pumps or intestinal transporters. The goal of this work was to, (1) Provide evidence to support the theory of mutual reinforcement. (2) Clarify the key targets of SHXXT and suggest which targets need further investigation. (3) Give advice for the clinical use of SHXXT to elevated the absorption of main constituents and eventually promote oral bioavailability. We search literatures in scientific databases with key words of "each main SHXXT constituent," in combination with "each main inflammatory pathway target molecule" or each main intestinal transporter, respectively. We report the effect of five main constituents on target molecules which lies in three main inflammatory signaling pathways, we as well investigate the interaction between constituents and intestinal transporter. We conclude, (1) The synergistic effect of constituents at both levels confirm the mutual reinforcement theory of TCM as it is proven in this work. (2) The effect of main constituents on downstream targets in nuclear need more further investigation. (3) Drug elevating the absorption of rhein, berberine and baicalein can be employed to promote oral bioavailability of SHXXT.

    Background Cytochrome P450 2C19 (CYP2C19) is an important drug-metabolizing enzyme (DME), which is responsible for the biotransformation of several kinds of drugs such as proton pump inhibitors, platelet aggregation inhibitors and antidepressants. Previous studies showed that Buchang NaoXinTong capsules (NXT) increased the CYP2C19 metabolic activity in vitro and enhanced the antiplatelet effect of clopidogrel in vivo. However, the underlying molecular mechanism remained unclear. In the present study, we examined whether Pregnane X receptor (PXR) plays a role in NXT-mediated regulation of CYP2C19 expression. Methods We applied luciferase assays, real-time quantitative PCR (qPCR), Western blotting and cell-based analysis of metabolic activity experiments to investigate the NXT regulatory effects on the CYP2C19 promoter activity, the mRNA/ protein expression and the metabolic activity. Results Our results demonstrated that NXT significantly increased the CYP2C19 promoter activity when co-transfected with PXR in HepG2 cells. Mutations in PXR responsive element abolished the NXT inductive effects on the CYP2C19 promoter transcription. Additionally, NXT incubation (150 and 250μg/mL) also markedly up-regulated endogenous CYP2C19 mRNA and protein levels in PXR-transfected HepG2 cells. Correspondingly, NXT leaded to a significant enhancement of the CYP2C19 catalytic activity in PXR-transfected HepG2 cells. Conclusion In summary, this is the first study to suggest that NXT could induce CYP2C19 expression via PXR activation. PMID:27467078

    Kai-Xin-San (KXS) is a traditional Chinese medicine that has been widely used for the treatment of emotion-related disease. However, the underlying mechanism remains largely unknown. The present study aimed to examine whether phospho-cAMP response element-binding protein (pCREB) and upstream components, such as extracellular signal-regulated kinase (ERK), phospho-ERK (pERK), phosphatidylinositol-3-kinase (PI3K), protein kinase B (Akt), glycogen synthase kinase 3β (GSK3β) and pGSK3β are associated with the antidepressive effect of KXS. In total, 24 male Wistar rats were randomly divided into three groups, including control (n=8, no treatment), induced with chronic unpredictable mild stress (CMS) (n=8), and CMS rats treated with KXS at dosage of 370 mg/kg/day orally. Primary hippocampal neuronal cultures were prepared from Wistar rats for cell survival and proliferation assays. In KXS rats, increased protein expression levels of pCREB, BDNF and tyrosine receptor kinase B (TrkB) were observed in the hippocampus and prefrontal cortex, compared with the CMS model group. Furthermore, increased expression levels of ERK, pERK, PI3K, Akt, and GSK3β were also detected in the hippocampus and prefrontal cortex of KXS-treated rats compared with CMS model rats and in primary hippocampal neuronal cells treated with KXS. These results suggest that pCREB and upstream components, including TrkB/ERK/CREB and TrkB/PI3 K/CREB, may contribute to the antidepressive effect induced by KXS. Further studies are required to confirm these findings. PMID:27882154

    Objectives. The study was to investigate the effects and mechanisms of Shen-Yuan-Dan (SYD) pharmacological postconditioning on myocardial ischemia/reperfusion (I/R) injury. Methods. In the in vivo experiment, myocardial injury markers and histopathology staining were examined. In the in vitro experiment, cell viability and cell apoptosis were, respectively, detected by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assays and Hoechst 33342 fluorochrome staining. The protein expressions of Bcl-2 and Bax were determined by immunocytochemistry assay. Results. Both low and high doses of SYD protected myocardium against I/R injury in rat model by reducing lactic dehydrogenase (LDH) and creatine kinase-MB (CK-MB) activity and malondialdehyde (MDA) content, increasing superoxide dismutase (SOD) activity and attenuating histopathology injury. Meanwhile, in the in vitro experiment, SYD promoted cell viability and inhibited the cardiomyocyte apoptosis. The level of Bcl-2 protein was restored to the normal level by SYD pharmacological postconditioning. In contrast, the Bax protein level was markedly reduced by SYD pharmacological postconditioning. These effects of SYD were inhibited by LY294002. Conclusions. The results of this study suggested that SYD pharmacological postconditioning has protective effects against myocardial I/R injury in both in vivo and in vitro models, which are related to activating the phosphatidylinositol 3-kinase/Akt (PI3K/Akt) pathway.

    Si Shen Wan (SSW) is used to effectively treat ulcerative colitis (UC) as a formula of traditional Chinese medicine. To explore the mechanism of SSW-inhibited apoptosis of colonic epithelial cell, the study observed mRNA expression of apoptosis-related molecules in p38 MAPK signal pathway in colonic mucosa in colitis mice treated with SSW. Experimental colitis was induced by 2,4,6-trinitrobenzene sulfonic acid (TNBS) in mice; meanwhile, the mice were administrated daily either SSW (5 g/kg) or p38 MAPK inhibitor (2 mg/kg) or vehicle (physiological saline) for 10 days. While microscopical evaluation was observed, apoptosis rate of colonic epithelial cell and mRNA expression of apoptosis-related molecules were tested. Compared with colitis mice without treatment, SSW alleviated colonic mucosal injuries and decreased apoptosis rate of colonic epithelial cell, while the mRNA expressions of p38 MAPK, p53, caspase-3, c-jun, c-fos, Bax, and TNF-α were decreased in the colonic mucosa in colitis mice treated with SSW, and Bcl-2 mRNA and the ratio of Bcl-2/Bax were increased. The present study demonstrated that SSW inhibited mRNA expression of apoptosis-related molecules in p38 MAPK signal pathway to downregulate colonic epithelial cells apoptosis in colonic mucosa in mice with colitis.

    Background Aromatase inhibitors (AIs) are widely used as an adjuvant endocrine treatment in postmenopausal women with early-stage breast cancer. One of the main adverse effects of AIs is musculoskeletal symptoms, which leads to a lower quality of life and poor adherence to AI treatment. To date, no effective management of aromatase inhibitor-associated musculoskeletal symptoms (AIMSS) has been developed. Methods/design To determine whether the traditional Chinese medicine Yi Shen Jian Gu granules could effectively manage AIMSS we will conduct a multicenter, randomized, double-blind, placebo-controlled clinical trial. Patients experiencing musculoskeletal symptoms after taking AIs will be enrolled and treated with traditional Chinese medicine or placebo for 12 weeks. The primary outcome measures include Brief Pain Inventory-Short Form, Western Ontario and McMaster Universities Osteoarthritis Index, and Modified Score for the Assessment and Quantification of Chronic Rheumatoid Affections of the Hands, which will be obtained at baseline and at 4, 8, 12 and 24 weeks. Discussion The results of this study will provide a new strategy to help relieve AIMSS. Trial registration ISCTN: ISRCTN06129599 (assigned 14 August 2013). PMID:24885324

    Chronic renal failure (CRF) is a serious disease related to increasing incidence and prevalence as well as decline in quality of life. Bu-Shen-Huo-Xue formula (BSHX), one of traditional herbal formulations, has been clinically employed to treat CRF for decades, but the mechanisms involved have not been investigated. In the present study, we investigated the effects of BSHX on some closely related parameters in 5/6 nephrectomy CRF rats. Rats with CRF were divided into five groups, namely, one control group, one enalapril group, and three BSHX treatment groups (0.25, 0.5, and 1 g/kg·d). The rats subjected to sham operation were used as a normal control. After eight weeks of treatment, BSHX significantly decreased the levels of Scr and BUN, downregulated the mRNA expression levels of TGF-β1, CTGF, NF-κB, TNF-α, and OPN, upregulated the mRNA expression of PPARγ, and reduced in situ expression of fibronectin and laminins. Histological findings also showed significant amelioration of the damaged renal tissue. BSHX protects 5/6 nephrectomy rats against chronic renal failure probably via regulating the expression of TNF-α, NF-κB, TGF-β1, CTGF, PPARγ, OPN, fibronectin, and laminins and is useful for therapy of CRF.

    Traditional Chinese medicine (TCM) research shows that Qi-Shen-Yi-Qi Dripping Pills (QSYQ) can promote ischemic cardiac angiogenesis. Studies have shown that microRNAs (miRNAs) are the key component of gene regulation networks, which play a vital role in angiogenesis and cardiovascular disease. Mechanisms involving miRNA by which TCM promotes ischemic cardiac angiogenesis have not been reported. We found that microRNA-223-3p (mir-223-3p) was the core miRNA of angiogenesis of rats ischemic cardiac microvascular endothelial cells (CMECs) and inhibited angiogenesis by affecting RPS6KB1/HIF-1α signal pathway in previous study. Based on the results, we observed biological characteristics and optimal dosage for QSYQ intervening in rats ischemic CMECs angiogenesis and concluded that QSYQ low-dose group had the strongest ability to promote angiogenesis of ischemic myocardium. Using miRNA chip and real-time PCR techniques in this study, we identified mir-223-3p as the pivotal miRNA in QSYQ that regulated angiogenesis of ischemic CMECs. From real-time PCR and western blot analysis, research showed that gene and protein expression of factors located RPS6KB1/HIF-1α signaling pathway, including HIF-1α, VEGF, MAPK, PI3K, and AKT, were significantly upregulated by QSYQ to regulate angiogenesis of ischemic CMECs. This study showed that QSYQ promote ischemic cardiac angiogenesis by downregulating mir-223-3p expression in rats ischemic CMECs. PMID:27057198

    Background Shen-Qi-Jie-Yu-Fang (SJ Fang) is a herbal preparation used in traditional Chinese medicine, and is a potentially important new therapeutic agent in postpartum depression (PPD). Previously, we have elucidated the effects of SJ Fang on hormone receptors and monoamine neurotransmitters involved in the hypothalamic-pituitary-adrenal and hypothalamic-pituitary-gonadal axes in PPD rats. However, the immune-modulating effects of SJ Fang in PPD are still unknown. In this study, we explored the effects of SJ Fang on the immune organs and subsets of T lymphocytes in PPD rats. Methods PPD was created in Sprague-Dawley rats by inducing hormone-simulated pregnancy followed by hormone withdrawal. After hormone withdrawal, the PPD rats were then treated with fluoxetine at 1, 2, and 4 weeks, and the SJ Fang rats were also treated at 1, 2, and 4 weeks. Depressive behavior in the rats was evaluated by the forced swim test, sucrose consumption test, and open field test. The thymus index and spleen index were calculated. Hematoxylin-eosin staining was used to identify pathological features in the thymus and spleen. CD3, CD4, and CD8 lymphocyte subsets were analyzed by flow cytometry. Results Both fluoxetine and SJ Fang decreased immobility time, increased sucrose consumption, an horizontal and vertical movement. After 4 weeks of treatment with fluoxetine or SJ Fang, the thymus index and spleen index were significantly higher than at baseline, and the morphology of the thymus and spleen were returning to normal. Two weeks after hormone withdrawal, subsets of T lymphocytes indicated a shift from immune activation to immune suppression, which was reversed by 4 weeks of treatment with fluoxetine or SJ Fang. Conclusion It is suggested that T-cell mediate immune responses which may play a role in the etiopathology of postpartum depression. SJ Fang had an antidepressant effect on the immune system in rats with PPD. PMID:26203247

    Background Shen-Qi-Jie-Yu-Fang (SJF) is composed of eight Chinese medicinal herbs. It is widely used in traditional Chinese medicine for treating postpartum depression (PPD). Previous studies have shown that SJF treats PPD through the neuroendocrine mechanism. Aim To further investigate the effect of SJF on the immune system, including the inflammatory response system and CD4+CD25+ regulatory T (Treg) cells. Materials and methods Sprague Dawley rats were used to create an animal model of PPD by inducing hormone-simulated pregnancy followed by hormone withdrawal. After hormone withdrawal, the PPD rats were treated with SJF or fluoxetine for 1, 2, and 4 weeks. Levels of Treg cells in peripheral blood were measured by flow cytometry analysis. Serum interleukin (IL)-1β and IL-6 were evaluated by enzyme-linked immunosorbent assay, and gene and protein expressions of IL-1RI, IL-6Rα, and gp130 in the hippocampus were observed by reverse-transcription polymerase chain reaction and Western blot. Results Serum IL-1β in PPD rats increased at 2 weeks and declined from then on, while serum IL-6 increased at 1, 2, and 4 weeks. Both IL-1β and IL-6 were downregulated by SJF and fluoxetine. Changes in gene and protein expressions of IL-1RI and gp130 in PPD rats were consistent with changes in serum IL-1β, and were able to be regulated by SJF and fluoxetine. The levels of Treg cells were negatively correlated with serum IL-1β and IL-6, and were decreased in PPD rats. The levels of Treg cells were increased by SJF and fluoxetine. Conclusion Dysfunction of proinflammatory cytokines and Tregs in different stages of PPD was attenuated by SJF and fluoxetine through the modulation of serum concentrations of IL-1β and IL-6, expressions of IL-1RI, and gp130 in the hippocampus, and CD4+CD25+ Treg cells in peripheral blood.

    Chronic kidney disease (CKD) is a worldwide public health concern with limited treatment options. The incidence of CDK is increasing and the disease is associated with a poor quality of life and a high financial cost of treatment. Shen-Kang (SK), a traditional Chinese herbal medicine, has been used clinically in the treatment of renal diseases for decades. This study was carried out to validate the therapeutic effects of SK on renal injury induced by 5/6 nephrectomy, as well as its effects on the apoptosis of proximal tubule epithelial cells (HK-2 cells), in an aim to elucidate its mechanisms of action. For this purpose, an animal model of renal injury was created by subjecting rats to a 5/6 nephrectomy. The rats in the sham-operated and model groups received distilled water, while the rats in the SK and enalapril (EN) groups were treated with SK or EN. The levels of blood urea nitrogen (BUN) and serum creatinine (SCr) were measured. Kidney tissues obtained from the rats were stained with hematoxylin and eosin. HK-2 cells were employed to investigate the effects of SK on the apoptosis of renal proximal tubule epithelial cells induced by treatment with hydrogen peroxide (H2O2). In addition, cell viability was measured by MTT assay. Apoptotic events were monitored by western blot analysis, flow cytometric analysis and nuclear morphological anlaysis. The levels of intracellular reactive oxygen species (ROS) were measured by flow cytometric analysis with dihydroethidium staining. The results revealed that the administration of SK to 5/6 nephrectomized rats for 1 week significantly decreased the levels of SCr and BUN. The morphological observations of the kidneys also indicated the amelioration of damage to renal tissue. Treatment of the HK-2 cells with SK significantly protected the cells from H2O2-induced apoptosis, as indicated by an increase in cell viability, the decrease in the cleavage of poly(ADP-ribose) polymerase (PARP) and fewer condensed nuclei.

    The structure and luminescence mechanisms of the CuInS2 quantum dots (QDs) after epitaxial growth of ZnS shell are in debate. The light absorption/emission spectroscopy reveals that after ZnS shell growth the cation diffusion at the CuInS2/ZnS interface results in formation of the alloyed CuxZn1- xInS2/ZnS:Cu QDs. These core/shell QDs exhibit dual-color photoluminescence with abnormal blue shift with decreasing excitation photon energy. The results show that the green and orange emissions originate separately from defects in the core and the shell. The absorption tail of the ZnS QDs turns from Urbach to Halperin-Lax type after Cu doping.

    Positive evidence from clinical trials has fueled growing acceptance of traditional Chinese medicine (TCM) for the treatment of cardiac diseases; however, little is known about the underlying mechanisms. Here, we investigated the nature and underlying mechanisms of the effects of YiXin-Shu (YXS), an antioxidant-enriched TCM formula, on myocardial ischemia/reperfusion (MI/R) injury. YXS pretreatment significantly reduced infarct size and improved viable myocardium metabolism and cardiac function in hypercholesterolemic mice. Mechanistically, YXS attenuated myocardial apoptosis by inhibiting the mitochondrial mediated apoptosis pathway (as reflected by inhibition of mitochondrial swelling, cytochrome c release and caspase-9 activity, and normalization of Bcl-2 and Bax levels) without altering the death receptor and endoplasmic reticulum-stress death pathways. Moreover, YXS reduced oxidative/nitrative stress (as reflected by decreased superoxide and nitrotyrosine content and normalized pro- and anti-oxidant enzyme levels). Interestingly, YXS upregulated endogenous nuclear receptors including LXRα, PPARα, PPARβ and ERα, and in-vivo knockdown of cardiac-specific LXRα significantly blunted the cardio-protective effects of YXS. Collectively, these data show that YXS is effective in mitigating MI/R injury by suppressing mitochondrial mediated apoptosis and oxidative stress and by upregulating LXRα, thereby providing a rationale for future clinical trials and clinical applications.

    Kai-xin-san (KXS), a Chinese herbal decoction prescribed by Sun Simiao in Beiji Qianjin Yaofang about 1400 years ago, contains Ginseng Radix et Rhizoma, Polygalae Radix, Acori Tatarinowii Rhizoma, and Poria. In China, KXS has been used to treat stress-related psychiatric diseases with the symptoms of depression and forgetfulness. Although animal study has supported the antidepression function of KXS, the mechanism in cellular level is still unknown. Here, a chemically standardized water extract of KXS was applied onto cultured astrocytes in exploring the action mechanisms of KXS treatment, which significantly stimulated the expression and secretion of neurotrophic factors, including NGF, BDNF, and GDNF, in a dose-dependent manner: the stimulation was both in mRNA and protein levels. In addition, the water extracts of four individual herbs did not significantly stimulate the expression of neurotrophic factors, which could explain the optimized effect of KXS in a herbal decoction. The KXS-induced expression of neurotrophic factors did not depend on signaling mediated by estrogen receptor or protein kinase. The results suggested that the antidepressant-like action of KXS might be mediated by an increase of expression of neurotrophic factors in astrocytes, which fully supported the clinical usage of this decoction.

    Objective To evaluate the effect of ShenQi FuZheng Injection (SFI) on cellular immunity and clinical efficacy in patients with advanced non small cell lung cancer(NSCLC) when combined with chemotherapy. Methods Electronic databases including EMBASE, PUBMED, the conference proceedings of the American Society of Clinical Oncology (ASCO), Cochrane, Chinese National Knowledge Infrastructure (CNKI), and Chinese Biological Medical disc(CBM) were searched, until July, 2015. The randomized controlled clinical studies reporting results of efficacy and immune function were collected according to the inclusion criteria. Cochrane handbook 5.1.0 was applied to assess the quality of included trials and Revman 5 software was used for data analysis. Results Fifteen studies including 1006 cases of advanced NSCLC were included based on the inclusion criteria. The results of meta-analysis showed that there were significant differences in percentages of CD3+ cells (SMD = 13.48; 95%CI: 8.11–18.85; p<0.01), CD4+ cells (SMD = 10.78; 95%CI, 6.38–15.18; p<0.01), NK [WMD = 8.59, 95% CI(3.97, 13.21), p = 0.003], and ratio of CD4+/ CD8+ (SMD = 0.32; 95%: 0.28–0.36; p<0.01) between SFI combination group and control group, whereas the difference was not significant in CD8+ (SMD = -1.44; 95%CI, -4.53–1.65; p = 0.36). Funnel plot, Begg's rank correlation test and Egger's linear regression analysis indicated that there was significant publication bias across studies. Conclusion SFI is effective to improve the efficacy of chemotherpay and function of cellular immunity in NSCLC patients, however, high quality RCTs are needed to further confirm the findings.

    The TE and NT cited under ink cap in Zheng lei ben cao (Classified Materia Medica) cannot be found in the contents and fragmentary volumes of Xin xiu ben cao (Newly Revised Materia Medica), yet can be seen in the "annotations of Shu ben cao (Materia Medica of Sichuan)", cited by Zhang Yuxi. This showed that the TE and NT were, in fact, coming from Shu ben cao, whose old name was Chong guang ying gong ben cao (Augmented Yinggong's Materia Medica). The so - called Yinggong was Li Ji, who compiled Tang ben cao (Materia Medica of the Tang Dynasty) by the imperial order, and gained the title Master Yingguogong, hence the title. Chong guang ying gong ben cao was meant revised Tang ben cao. This was the reason why Tang Shenwei called Shu ben cao as Tang ben cao right away in his Zheng lei ben cao.

    Large-scale plasma flows in the Sun's convection zone likely play a major role in solar dynamics on decadal timescales. In particular, quantifying meridional motions is a critical ingredient for understanding the solar cycle and the transport of magnetic flux. Because the signal of such features can be quite small in deep solar layers and be buried in systematics or noise, the true meridional velocity profile has remained elusive. We perform time-distance helioseismology measurements on several years worth of Global Oscillation Network Group Doppler data. A spherical harmonic decomposition technique is applied to a subset of acoustic modes to measure travel-time differences to try to obtain signatures of meridional flows throughout the solar convection zone. Center-to-limb systematics are taken into account in an intuitive yet ad hoc manner. Travel-time differences near the surface that are consistent with a poleward flow in each hemisphere and are similar to previous work are measured. Additionally, measurements in deep layers near the base of the convection zone suggest a possible equatorward flow, as well as partial evidence of a sign change in the travel-time differences at mid-convection zone depths. This analysis on an independent data set using different measurement techniques strengthens recent conclusions that the convection zone may have multiple 'cells' of meridional flow. The results may challenge the common understanding of one large conveyor belt operating in the solar convection zone. Further work with helioseismic inversions and a careful study of systematic effects are needed before firm conclusions of these large-scale flow structures can be made.

    The structure and dynamics of active regions beneath the surface show significant uncertainties due to our limited understanding of the wave interaction with magnetic field. Recent numerical simulations further demonstrate that the atmosphere above the photospheric levels also modifies the seismic observables at the surface. Thus the key to improve helioseismic interpretation beneath the active regions requires a synergy between models and helioseismic inferences from observations. In this context, using data from Global Oscillation Network Group and from Helioseismic Magnetic Imager and Atmospheric Imaging Assembly onboard Solar Dynamics Observatory, we characterize the spatio-temporal power distribution in and around active regions. Specifically, we focus on the power enhancements seen around active regions as a function of wave frequencies, strength, inclination of magnetic field and observation height as well as the relative phases of the observables and their cross-coherence functions. It is expected that these effects will help us to comprehend the interaction of acoustic waves with magnetic field in the solar photosphere.

    The early stages and capsulogenetic stages of sporogenesis of Myxobolus kwangsiensis were studied in detail by electron microscopy. M. kwangsiensis is an intracellular myxosporean infecting the epithelial cells of kidney tubules of young dace Labeo rohita. The M. kwangsiensis sporogensis presents the typical features of myxosporea. The initial stages are multinucleate primary cells, with one primary cell typically enclosing one secondary cell. The secondary cells are formed directly by cytokinesis inside the primary cells. The primary cell participates in the formation of the secondary cell nucleus. The nuclear division of primary cell is asynchronous by amitosis. The parasitic organisms may degenerate inside the epithelial cells at any stage. The modes of sporoblast formation, the typical features of myxosporea and the cause of its degradation are discussed.

    Helioseismic analysis of solar global oscillations allows investigation of the internal structure of the Sun. One important test of the reliability of the inferences from helioseismology is that the results from independent sets of contemporaneous data are consistent with one another. Here we compare mode frequencies from the Global Oscillation Network Group and Michelson Doppler Imager on board SOHO and resulting inversion results on the Sun's internal structure. The average relative differences between the data sets are typically less than 1 x 10(exp -5) substantially smaller than the formal errors in the differences; however, in some cases the frequency differences show a systematic behavior that might nonetheless influence the inversion results. We find that the differences in frequencies are not a result of instrumental effects but are almost entirely related to the data pipeline software. Inversion of the frequencies shows that their differences do not result in any significant effects on the resulting inferences on solar structure. We have also experimented with fitting asymmetric profiles to the oscillation power spectra and find that, compared with the symmetric fits, this causes no significant change in the inversion results.

  4. Shen 4-marker miRNA panel for lung cancer — EDRN Public Portal

    We initially validated expressions of a set of miRNAs in paired lung tumor tissues and plasma specimens from 28 stage I NSCLC patients by real-time quantitative reverse transcription PCR, and then evaluated diagnostic value of the plasma miRNAs in a cohort of 58 NSCLC patients and 29 healthy individuals. The altered miRNA expressions were reproducibly confirmed in the tumor tissues. The miRNAs were stably present and reliably measurable in plasma. A logistic regression model with the best prediction was defined on the basis of the four genes (miRNA-21, -126, -210, and 486-5p), yielding 86.22% sensitivity and 96.55% specificity in distinguishing NSCLC patients from the healthy controls.

    Our reverberation mapping (RM) field is the Pan-STARRS 1 (PS1) Medium Deep Field (MDF) MD07 (RAJ2000=213.704, DEJ2000=+53.083), which is a 7deg2 field within the CFHT-LS W3 field. This field is fully covered in the SDSS-I/II and SDSS-III BOSS footprints. The final RM sample contains 849 quasars, each of which was assigned a fiber on the RM plates. The remaining fibers were allocated to calibration sources, including 70 spectrophotometric standard stars, 80 sky fibers, and 1 LRG target (enforced by the BOSS tiling algorithm, but actually not tiled on any existing object in SDSS imaging). The BOSS spectroscopic observations were acquired during 7 dark/gray runs from 2014 January 1 to 2014 July 3. The separation between epochs in a given run is roughly 3-4 days, but varies from run to run under different weather conditions. Typically five epochs were taken for each run when weather permitted, totaling 32 epochs. The main portion of the RM imaging of our program is obtained with the CFHT/MegaCam and the Steward Observatory Bok 2.3m/90Prime. Given that our RM sample covers a wide redshift range, the photometric monitoring is performed in the SDSS g band and i band to sample the quasar continuum at low and high redshifts, respectively. We also had six nights of KPNO-4m (Mayall)/MOSAIC-1.1 observation to perform multi-band (Ugriz) imaging of the RM field. (4 data files).

    Inflammatory bowel disease increases the risks of human colorectal cancer. In this study, the effects of Salvia miltiorrhiza extract (SME) on chemically-induced colitis in a mouse model were evaluated. Chemical composition of SME was determined by HPLC analysis. A/J mice received a single injection of AOM 7.5 mg/kg. After one week, these mice received 2.5% DSS for eight days, or DSS plus SME (25 or 50 mg/kg). DSS-induced colitis was scored with the disease activity index (DAI). Body weight and colon length were also measured. The severity of inflammatory lesions was further evaluated by colon tissue histological assessment. HPLC assay showed that the major constituents in the tested SME were danshensu, protocatechuic aldehyde, salvianolic acid D, and salvianolic acid B. In the model group, the DAI score reached its highest level on Day 8, while the SME group on both doses showed a significantly reduced DAI score (both p < 0.01). As an objective index of the severity of inflammation, colon length was significantly shorter in the model group than the vehicle group. Treatment with 25 and 50 mg/kg of SME inhibited the shortening of colon in a dose-related manner (p < 0.05 and p < 0.01, respectively). SME groups also significantly reduced weight reduction (p < 0.05). Colitis histological data supported the pharmacological observations. Thus, Salvia miltiorrhiza could be a promising candidate in preventing and treating colitis and in reducing the risks of inflammation-associated colorectal cancer.

  11. Real time flood forecasting in the Nan Basin, Thailand, by using a distributed Xin'anjiang Model

    NASA Astrophysics Data System (ADS)

    Chen, Xiaohong; Qiu, Xiaobin

    2015-04-01

    Taking Nan basin in Thailand as a research case, on the basis of DEM, this paper extracts the digital information of Nan basin and divides it into ten sub-basins, considering the land usage and terrain distribution, to construct the distributed Xinanjiang model. Before the model simulation, various digital basin information is established involving elevation matrix, river net matrix, direction matrix and so on. The three-water-source Xinanjiang model is adopted in the grids to calculate the runoff yield under a specific precipitation in grids, and then all the water flows of the grids are convoluted to the sub-basin's outlet to synthesize the runoff process of a subbasin. Eventually the subbasin runoff is routed to the basin outlet to obtain runoff process of the whole basin with real-time correction. The model parameters are calibrated by using the trial and error method. The sensitivity and uncertainty of the parameters are analyzed. The main achievements of this paper are as follows. (1) The basin information is extracted and the digital NAN basin is constructed on the basis of DEM data. As a result, a series of basin information matrix and digital Nan basin are generated. (2) The constant flow in grids and isochrones concept are used to replace the unit hydrograph of sub-basins. The basin discharge process is obtained through calculating the grid runoff yield and subbasin runoff convolution and routing the subbasin runoffs to the basin outlet. (3) The model is calibrated on more than 50 historical flood processes. The sensitivity and uncertainty of model parameters are analyzed by the perturbation analysis method, showing that some parameters, including KC, KKG, KKSS, WUM, KG, WLM, KSS and WDM are more sensitive. At the same time, the model uncertainty is analyed by the GLUE method and the results illustrate that the simulation effect depends on the values of parameter group while the observed runoff is in the uncertainty range. (4) The calculated discharge process is adaptively corrected by Attenuation memory least squares method to obtain final forecasting flood process. Verifications of this real-time flood forecasting model show high precision and the model system has been practically used in Thailand.

    The first reported SmAPF phase, formed from the bent core mesogen W586, exhibits interesting and useful electrooptics.(1) Specifically, in teflon-aligned cells, upon application of an electric field, modulation of the birefringence is observed without rotation of the apparent optic axis. In addition, optical latching is observed, providing the long sought but never before seen "infinitely multistable" ferroelectric LC electrooptic switch. Based upon careful measurements of the cell behavior, the polar order parameter at temperatures just above the transition to a lower-lying smectic phase is close to unity. This suggested potential application of the phase as a host for controlled polar alignment of guest molecules. One clear application of the system is for electronic electrooptic modulation of light at telecommunications wavelengths (Kerr effect), which can be obtained in materials with polar orientation of visible dyes. Background and results of recent experiments in the host-guest chemistry of the W586 SmAPF phase, showing good orientation of designed NLO dyes, will be presented. (1) a) Reddy, R.

    Objective. We investigated the expression levels of both FOSL2 mRNA and protein as well as evaluating DNA methylation in the blood of type 2 diabetes mellitus (T2DM) Uyghur patients from Xinjiang. This study also evaluated whether FOSL2 gene expression had demonstrated any associations with clinical and biochemical indicators of T2DM. Methods. One hundred Uyghur subjects where divided into two groups, T2DM and nonimpaired glucose tolerance (NGT) groups. DNA methylation of FOSL2 was also analyzed by MassARRAY Spectrometry and methylation data of individual units were generated by the EpiTyper v1.0.5 software. The expression levels of FOS-like antigen 2 (FOSL2) and the protein expression levels were analyzed. Results. Significant differences were observed in mRNA and protein levels when compared with the NGT group, while methylation rates of eight CpG units within the FOSL2 gene were higher in the T2DM group. Methylation of CpG sites was found to inversely correlate with expression of other markers. Conclusions. Results show that a correlation between mRNA, protein, and DNA methylation of FOSL2 gene exists among T2DM patients from Uyghur. FOSL2 protein and mRNA were downregulated and the DNA became hypermethylated, all of which may be involved in T2DM pathogenesis in this population. PMID:28050569

  19. Traditional Chinese Medicine Induced Liver Injury

    PubMed Central

    2014-01-01

    Traditional Chinese Medicine (TCM) is popular around the world and encompasses many different practices with particular emphasis on herbal TCM. Using the PubMed database, a literature search was undertaken to assess the extent herbal TCM products exert rare hepatotoxicity. Analysis of reported cases revealed numerous specified herbal TCM products with potential hepatotoxicity. Among these were An Shu Ling, Bai Fang, Bai Xian Pi, Ban Tu Wan, Bo He, Bo Ye Qing Niu Dan, Bofu Tsu Sho San, Boh Gol Zhee, Cang Er Zi, Chai Hu, Chaso, Chi R Yun, Chuan Lian Zi, Ci Wu Jia, Da Chai Hu Tang, Da Huang, Du Huo, Gan Cao, Ge Gen, Ho Shou Wu, Hu Bohe You, Hu Zhang, Huang Qin, Huang Yao Zi, Hwang Geun Cho, Ji Gu Cao, Ji Ji, Ji Xue Cao, Jiguja, Jin Bu Huan, Jue Ming Zi, Kamishoyosan, Kudzu, Lei Gong Teng, Long Dan Xie Gan Tang, Lu Cha, Ma Huang, Mao Guo Tian Jie Cai, Onshido, Polygonum multiflorum, Qian Li Guang, Ren Shen, Sairei To, Shan Chi, Shen Min, Shi Can, Shi Liu Pi, Shou Wu Pian, Tian Hua Fen, White flood, Wu Bei Zi, Xi Shu, Xiao Chai Hu Tang, Yin Chen Hao, Zexie, Zhen Chu Cao, and various unclassified Chinese herbal mixtures. Causality was firmly established for a number of herbal TCM products by a positive reexposure test result, the liver specific scale of CIOMS (Council for International Organizations of Medical Sciences), or both. Otherwise, the quality of case data was mixed, especially regarding analysis of the herb ingredients because of adulteration with synthetic drugs, contamination with heavy metals, and misidentification. In addition, non-herbal TCM elements derived from Agaricus blazei, Agkistrodon, Antelope, Bombyx, Carp, Fish gallbladder, Phellinus, Scolopendra, Scorpio, and Zaocys are also known or potential hepatotoxins. For some patients, the clinical course was severe, with risks for acute liver failure, liver transplantation requirement, and lethality. In conclusion, the use of few herbal TCM products may rarely be associated with hepatotoxicity in some

  17. The history of ginseng in the management of erectile dysfunction in ancient China (3500-2600 BCE).

    2012-01-01

    Emperor Shen-Nung was the second of China's mythical emperors (3500-2600 BCE). Widely considered the father of Chinese medicine, he catalogued over 365 species of medicinal plants which he personally tasted. Through his treatise 'Shen Nung Benchau Jing', we relive Emperor Shen-Nung's contribution to urology with reference to his management of erectile dysfunction. Time-related sources in medical and historical literature were reviewed, including the 'Shen Nung Benchau Jing' (The medicine book of Emperor Shen-Nung), archives and manuscripts at the Wellcome History of Medicine Collection, the Royal Society of Medicine, London, The Hong Kong Museum of Medical Sciences, and The Museum of Medical History, Shanghai, China. Chinese traditional herbal medicine began approximately 5000 years ago. Agricultural clan leader, Emperor Shen-Nung, was said to have a 'crystal-like belly' to watch the reactions in his own stomach of the herbs he collected. Ginseng was among of Shen Nung's contributions to herbal medicine. He experienced a warm and sexually pleasurable feeling after chewing the root. He advocated this as a treatment for erectile dysfunction and used it to stimulate sexual appetite. The reputation of ginseng as an aphrodisiac is based on the doctrine of signatures, since the adult root has a phallic shape. Shen-Nung believed that ginseng's resemblance to the human form is proof of its rejuvenative and aphrodisiac properties. It was believed that the closer the similarity to the human figure, the more potent the root. The use of ginseng for erectile dysfunction by Emperor Shen-Nung was unique for its time. It continues to hold parallels as a modern-day herbal aphrodisiac 5000 years on.

    A Gram-stain-negative bacterium, designated XIN-1(T), was isolated from a farmland river sludge sample in Suzhou, China. Cells of strain XIN-1(T) were strictly aerobic, non-motile and rod-shaped. Strain XIN-1(T) grew optimally at pH 7.0 and 28 °C. Phylogenetic analysis of the 16S rRNA gene sequences showed that strain XIN-1(T) was most closely related to Flavobacterium hauense BX12(T) (98.2 % sequence similarity), followed by Flavobacterium beibuense F44-8(T) (96.3 %). The major respiratory quinone was menaquinone-6 and the major polar lipid was phosphatidylethanolamine. The major fatty acids (>5 %) were summed feature 3 (comprising C16 : 1ω7c and/or C16 : 1ω6c), summed feature 4 (comprising iso-C17 : 1 I and/or anteiso-C17 : 1 B), iso-C15 : 0, C16 : 0 and iso-C17 : 0 3-OH. The genomic DNA G+C content of strain XIN-1(T) was 39.8 mol%. Strain XIN-1(T) showed low DNA-DNA relatedness with F. hauense BX12(T) (38.7±0.5 %). On the basis of genotypic and phenotypic data, strain XIN-1(T) is considered to represent a novel species of the genus Flavobacterium, for which the name Flavobacterium suzhouense sp. nov. is proposed. The type strain is XIN-1(T) ( = CCTCC AB 2014200(T) = KCTC 42107(T)).

    Xin xiu ben cao (Newly Revised Materia Medica), also called Tang ben cao (Materia Medica of the Tang Dynasty) is the first state pharmacopoeia in the world, the original edition of which was lost yet cited by various books. After analyzing the TE in Jia You ben cao (Materia Medica of Jia You Reign) supplemantarily cited by Zhang Yuxi in the Song Dynasty, the author holds that Zhang himself didn't witness Xin xiu ben cao (Newly Revised Materia Medica) and the so-called TE ought to be derived from Shu ben cao (Materia Medica of Sichuan) because both share the same features. Inference can also be drawn that Xin xiu ben cao (Newly Revised Materia Medica) might have been lost at the time when Jia You ben cao (Materia Medica of Jia You Reign) was compiled in the 2nd year of Jia You Reign (A.D.1057). As the TE was not directly extracted from Xin xiu ben cao (Newly Revised Materia Medica), the trustworthiness of the texts allegedly cited from Xin xiu ben cao should be evaluated in many ways and it should be dealt with prudently while recompiling Xin xiu ben cao (Newly Revised Materia Medica).

  3. Effect of H2O2 on fiber initiation using fiber retardation initiation mutants in cotton (Gossypium hirsutum).

    2010-03-15

    Single-celled fibers initiate at anthesis from cotton seed epidermal cells of normal developmental cotton cultivars; however, fiber initiation is retarded in some cotton fiber mutants. In this study, the relationship between genes associated with fiber initiation retardation and fiber initiation development was investigated using three cotton fiber developmental mutants: recessive naked seed n2; dominant naked seed N1; and Xinxiangxiaoji Linted-Fuzzless Mutant (XinFLM); with genetic standard line TM-1 (TM-1) as control. Retardation during fiber initiation development was observed in N1 and XinFLM by scanning electron microscope (SEM) analysis. Reverse transcription-polymerase chain reaction (RT-PCR) analysis of genes related to the fiber initiation development showed that the expression of GhEXP1 and GhMYB25 was lower in N1 and XinFLM than in TM-1 and n2, however, the expression of GhTTG1 and GhTTG3 in XinFLM and n2 was higher than in TM-1 and N1. In vivo and in vitro treatments on ovules demonstrated that 30% hydrogen peroxide (H2O2) could prevent fiber initiation retardation in XinFLM, but no evident effect on N1. To further confirm the relationship between gene expression and the effects of H2O2 in XinFLM, qRT-PCR analysis of four differentially expressed genes was performed using -1d post-anthesis (DPA) ovules of XinFLM treated for 24 and 48h with 30% H2O2 and H2O, respectively, with 0 and 1 DPA untreated ovules from XinFLM and TM-1 as control. The results showed that the expression of GhMYB25 and GhEXP1 showed significant difference in XinFLM after -1 DPA ovule treated for 24h relative to the untreated or H2O-treated ovules, with the expression of GhMYB25 increased significantly and that of GhEXP1 decreased. This implied that H2O2 might be one of the upstream signal molecules affecting the expression of GhMYB25 and GhEXP1 genes. The fiber initiation retardation in XinFLM might be related to the production of reactive oxygen species (ROS).

    To guarantee the security of communication in the public channel, many key agreement protocols have been proposed. Recently, Gong et al. proposed a key agreement protocol based on chaotic maps with password sharing. In this paper, Gong et al.'s protocol is analyzed, and we find that this protocol exhibits key management issues and potential security problems. Furthermore, the paper presents a new key agreement protocol based on enhanced Chebyshev polynomials to overcome these problems. Through our analysis, our key agreement protocol not only provides mutual authentication and the ability to resist a variety of common attacks, but also solve the problems of key management and security issues existing in Gong et al.'s protocol.

    For the first time, the ultra-low oscillation mode of the sunspot magnetic field strength has been detected with a high degree of confidence by ground-based observations of sunspots with the Global Oscillation Network Group (GONG) network of telescopes. Synchronous series of magnetograms derived from the GONG and Solar and Heliospheric Observatory/Michelson Doppler Imager (SOHO/MDI) have been processed. They were obtained on September 27-30, 2010, for the active region NOAA 11109 with a total duration of 80 h. The periods of magnetic field oscillations found by space data coincide with the periods defined with GONG. This confirms the physical reality of the oscillatory process. The power spectrum contains harmonics with periods of 26 h, 8-10 h, and 3-4 h.

  14. Hardened Lava Meets Wind on Mars

    NASA Technical Reports Server (NTRS)

    2006-01-01

    NASA's Mars Exploration Rover Spirit used its microscopic imager to capture this spectacular, jagged mini-landscape on a rock called 'GongGong.' Measuring only 3 centimeters (1.2 inches) across, this surface records two of the most important and violent forces in the history of Mars -- volcanoes and wind.

    GongGong formed billions of years ago in a seething, stirring mass of molten rock. It captured bubbles of gases that were trapped at great depth but had separated from the main body of lava as it rose to the surface. Like taffy being stretched and tumbled, the molten rock was deformed as it moved across an ancient Martian landscape. The tiny bubbles of gas were deformed as well, becoming elongated. When the molten lava solidified, the rock looked like a frozen sponge.

    Far from finished with its life, the rock then withstood billions of years of pelting by small sand grains carried by Martian dust storms that sometimes blanketed the planet. The sand wore away the surface until, little by little, the delicate strands that enclosed the bubbles of gas were breached and the spiny texture we see today emerged.

    Even now, wind continues to deposit sand and dust in the holes and crevices of the rock.

    Similar rocks can be found on Earth where the same complex interplay of volcanoes and weathering occur, whether it be the pelting of rocks by sand grains in the Mojave desert or by ice crystals in the frigid Antarctic.

    GongGong is one of a group of rocks studied by Spirit and informally named by the Athena Science Team to honor the Chinese New Year (the Year of the Dog). In Chinese mythology, GongGong was the god-king of water in the North Land. When he sacrificed his life to knock down Mount BuZhou, he defeated the bad Emperor in Heaven, freed the sun, moon and stars to go from east to west, and caused all the rivers in China to flow from west to east.

    Spirit's microscopic imager took this image during on the rover's 736th day, or sol, of

  18. Large Scale Solar Velocities on Time Scales up to Thirty Days

    NASA Astrophysics Data System (ADS)

    Beck, John Gunther

    1997-08-01

    This work studied solar supergranulation and methods of improving solar oscillation measurements. The supergranulation size scale and lifetime were found to be independent of heliographic latitude. The observed supergranule size scales were 31.7 ± 1.6 Mm in the East-West direction and 32.0 ± 1.6 Mm in the North-South direction; the mean lifetime was 23.4 ± 1.1 hours. Persistent granules were observed with the sizes of ~60 Mm and lifetimes of up to 160 hours, these features were found to affect supergranule lifetime measurements. Improvements of solar oscillation measurements were sought through three means: active region noise modeling, simulation the GONG instrument, and merging GONG data with IRIS data. The active region noise model, MDV, was tested and found promising. A simulation revealed a transmission profile ripple in the GONG instrument which could explain the observed velocity errors. A technique for merging GONG and IRIS data was developed and tested with satisfactory results.

    This paper reviews the taxonomic and biodiversity studies of the deep-sea invertebrates in the South China Sea based on the samples collected by the Chinese manned deep-sea submersible Jiaolong. To date, six new species were described, including the sponges Lophophysema eversa Gong, Li & Qiu, 2014, Saccocalyx microhexactin Gong, Li & Qiu, 2015, and Semperella jiaolongae Gong, Li & Qiu, 2015 as well as the crustaceans Uroptychus jiaolongae Dong & Li, 2015, Uroptychus spinulosus Dong & Li, 2015 and Globospongicola jiaolongi Jiang, Kou & Li, 2015, and some newly recorded species from the South China Sea were reported. The Bathymodiolus platifrons-Shinkaia crosnieri deep-sea cold seep community was reported (Li, 2015), as was the mitochondrial genome of the glass sponge Lophophysema eversa Gong, Li & Qiu, 2014 (Zhang et al., 2015). The population structures of two dominant species, the shrimp Shinkaia crosnieri and the mussel Bathymodiolus platifrons, from the cold seep Bathymodiolus platifrons-Shinkaia crosnieri community in the South China Sea and the hydrothermal vents in the Okinawa Trough, were compared using molecular analysis. The systematic position of the shrimp genus Globospongicola was discussed based on 16S rRNA gene sequences. This article is protected by copyright. All rights reserved.

  3. Obituary: Clifford G. Toner (1959-2009)

    NASA Astrophysics Data System (ADS)

    Hill, Frank

    2011-12-01

    Cliff Toner passed away unexpectedly at home in Tucson, Arizona on March 29, 2009. For most of his career, Cliff was involved with the Global Oscillation Network Group (GONG), a facility of the National Solar Observatory in Tucson, Arizona. GONG is a set of instruments around the world to observe the inside of the sun using the sound that is trapped below the solar surface. This science is called helioseismology. Cliff Toner was born on December 8, 1959 in New Westminster, British Columbia near the western coast of Canada. After receiving his B.Sc. in Physics & Astronomy at the University of British Columbia at Vancouver in 1981, he headed east to the University of Western Ontario in London. His graduate school period was spent in collaboration with David F. Gray, with whom he received both an M.Sc. in Astronomy in 1984, and a Ph.D. in Astronomy in 1988. Toner actually wrote two theses at UWO, one on "Line Asymmetries in F, G, and K Supergiants and Bright Giants" for his M.Sc., and the other on "The Time Variability of Spectral Line Asymmetries and Equivalent Widths for the G8 Dwarf ? Boo A: Evidence for a Starpatch" for his Ph.D. After graduate school, Cliff Toner left the cool climate of Canada in 1988 and accepted a postdoctoral position in the warmer temperatures of Hawai'i at the Institute for Astronomy located at the University of Hawai'i in Honolulu. There he worked primarily with Barry LaBonte. At first, he continued his work on ? Boo A, but he became interested in the sun and helioseismology. This led to the discovery of halos of enhanced high-frequency acoustic power surrounding solar active regions (Ap.J. 415, 847). At the end of his post-doc, Cliff Toner was hired by the GONG project as a Data Scientist in 1991. He quickly tackled the problem of merging the data from the six GONG sites, which was the major data reduction challenge facing GONG at the time. In parallel, he and Stuart Jefferies developed an algorithm to measure the radii of full-disk solar

    Polycystic ovarian syndrome (PCOS) is one of the most popular diseases that cause menstrual dysfunction and infertility in women. The present paper is a brief retrospection on the progress in treatment of PCOS caused infertility with integrative Chinese and Western medicine (ICWM). It can be seen from these materials that using traditional Chinese medicine (TCM) recipes formulated by Shen-replenishing herbs or acupuncture to reinforce Gan-Shen, regulate Chong-Ren Channels in treating PCOS, stable clinical efficacy could be obtained, with less adverse reaction, though the effect initiated somewhat late. Whereas, when Shen-replenishing recipe and acupuncture are combined with hormone or ovulation promoting drugs of Western medicine, the above-mentioned shortcomings would be overcome. So, this combined therapy is frequently used in clinical practice.

    commercial stages, these one-dimensional structures have a number of advantages including the lower melting point of materials at the nanoscale and the potential for further reductions in size and programming current and power requirements. Investigations of one-dimensional structures have provided an enduring stimulant to both fundamental and applied research in nanoscale science and technology research. William Plomer once described creativity as 'the ability to connect the apparently unconnected'. It could perhaps be said that nanowires bring creativity to the ability to connect.

    We have carried out ab-initio calculations of the local structure of Mn and Ni in the Mn2Ni1.5In0.5 alloy with different site occupancies in order to understand the similarities in martensitic and magnetic properties of Mn2Ni1+xIn1-x and Ni2Mn1+xIn1-x alloys. Our results show that in Mn2Ni1+xIn1-x alloys, there is a strong possibility of Mn atoms occupying all the three X, Y, and Z sites of the X2YZ Heusler structure, while Ni atoms preferentially occupy the X sites. Such a site occupancy disorder of Mn atoms is in addition to a local structural disorder due to size differences between Mn and In atoms, which is also present in Ni2Mn1+xIn1-x alloys. Further, a comparison of the calculations with experimental x-ray absorption fine structure at the Mn and Ni K edges in Mn2-yNi1.6+yIn0.4 (-0.08 ≤ y ≤ 0.08) indicates a strong connection between martensitic transformation and occupancy of Z sites by Mn atoms.

    2015-09-01

    I explore the historical and cultural shifts that underlie the normalization of the term dépréshen and the emergence of public psychiatric discourses in 1990s Iran. I do this by investigating the cultural sensibilities of a particular generation, the self-identified 1980s generation, and the ways they situate what is perceived as dépréshen in social anomie and the memories of the Iran-Iraq war. I argue that psychiatrization of psychological distress in Iran was not simply a de-politicizing hegemonic biomedical discourse, but that the contemporary Iranian discourses of psychological pathology and social loss evolved in public, hand-in-hand, through the medicalization of post-war loss. Psychiatric subjectivity describes conditions where individuals internalize psychiatry as a mode of thinking, and performatively articulate not only their desires, hopes, and anxieties, but also historical losses as embodied in individual and collective brains. I underscore my interlocutors' simultaneous historicization and medicalization of their dépréshen, arguing that psychiatrically medicalized individuals are performative actors in the discursive formation of both biomedical and social truth. Dépréshen, in the larger sense of the word, has become one way to navigate ruptured pasts, slippery presents, and uncertain futures.

    Estuarine and coastal waters are referred to as Case 2 waters and much more optically complex because the optical properties of chlorophyll-a (Chla), non-algae particles (NAP), and colored dissolved organic matter (CDOM) and their concentrations are subjected to potentially large and independent variations. As for the Yangtze estuarine and coastal water, its relatively higher concentration of Suspended Particulate Matter (SPM) among world's estuarine and coastal waters provides a reference test site for studying ocean colour algorithms and remote sensing applications in wide-range sediment concentration water and extremely turbid water. Regarding the Dragon 3 project, algorithms for atmosphere correction were improved (Salama and Shen, 2010; Shen and Verhoef, 2010); several novel models to retrieve bio-optical properties, such as concentrations of SPM, Chla and inherent optical properties(IOPs), were also developed for medium and extremely turbid waters, that is the SERT model (Shen et al., 2010), the SCI algorithm (Shen et al., 2010) and the 2SeaColor model (Salama and Verhoef, 2014). Data acquired from both in-situmeasurements and satellite were used for models development and improvement and the results are shown as follows. In general, four aspects of the work have been involved in by the Chinese and European partners by far.

  13. Highly sensitive and selective determination of fluorine ion by graphene oxide/nanogold resonance Rayleigh scattering-energy transfer analytical platform.

    PubMed

    Liang, Aihui; Peng, Jing; Liu, Qingye; Wen, Guiqing; Lu, Zhujun; Jiang, Zhiliang

    2015-08-15

    In pH 4.0 acetate buffer solution, fluorine ions react with fluorine reagent (FR) and La(III) to generate blue ternary complex that exhibited strong absorption at about 370 nm. Upon addition of graphene oxide/nanogold (GO/NG) as resonance Rayleigh scattering (RRS) spectral probe with strong RRS peak at 370 nm, the color changed to gray, and the RRS intensity decreased with the increase of fluorine ion concentration due to the RRS energy transfer (RRSET) from GO/NG to the complex. Under the selected condition, the decreased RRS peak ΔI370 nm was linear to fluorine ion concentration in the range of 6.0 × 10(-8)-1.3 × 10(-5)mol/L, with a detection limit of 3.0 × 10(-8)mol/L F(-). This RRSET method was applied to the analysis of fluorine in toothpaste and water samples, with satisfactory results.

    Ordos area is the desert-wind erosion desertification steppe transition zone and the complex ecological zone. As the research area, Ordos City has the similar natural geographic environment to ShenDong coalfield. To research its ecological patterns and natural evolution law, it has instructive to reveal temporal and spatial changes of ecological environment with artificial disturbance in western mining. In this paper, a time series of AVHRR-NDVI(Normalized Difference Vegetation Index) data was used to monitor the change of vegetation temporal and spatial dynamics from 1981 to 2006 in Ordos City and ShenDong coalfield, where were as the research area. The MVC (Maximum Value Composites) method, average operation, linear regression, and gradation for NDVI change trend were used to obtained some results, as follows: ¬vegetation coverage had obvious characteristics with periodic change in research area for 26 years, and vegetation growth peak appeared on August, while the lowest appeared on January. The extreme values in Ordos City were 0.2351 and 0.1176, while they were 0.2657 and 0.1272 in ShenDong coalfield. The NDVI value fluctuation was a modest rise trend overall in research area. The extreme values were 0.3071 and 0.1861 in Ordos City, while they were 0.3454 and 0.1904 in ShenDong coalfield. In spatial distribution, slight improvement area and slight degradation area were accounting for 42.49% and 8.37% in Ordos City, while slight improvement area moderate improvement area were accounting for 70.59% and 29.41% in ShenDong coalfield. Above of results indicated there was less vegetation coverage in research area, which reflected the characteristics of fragile natural geographical environment. In addition, vegetation coverage was with a modest rise on the whole, which reflected the natural environment change.

    Non-ion additive hole-transporting material (HTM) of hydrophobic oligothiophene derivative named DR3TBDTT and triphenylamine derivative of N,N'-di(3-methylphenyl)-N,N-diphenyl-4,4-diaminobiphenyl (TPD) were used for the organic-inorganic hybrid perovskite solar cells. The power conversion efficiency (PCE) was comparable to the device using Li-TFSI doped spiro-MeOTAD. Moreover, the PCE decreases by only 10% after approximately 1000 h without encapsulation, which suggests an alternative method to improve the stability of perovskite solar cells[1-3 ]. Figure 1.

    2010-03-01

    The fundamental toughening mechanism of DN gels [1] is of great interest to researchers. Extensive experimental and theoretical studies have been performed to explain this mechanism [2-7]. Yielding and necking deformation [2] that was observed through tensile tests and rate-independent hysteresis [3] observed through cyclic loading tests have indicated that DN gels can accumulate internal damage before the suffering macroscopic fracture; after damage accumulation, the DN gels become much softer. We assume that on the microscopic level, yielding is caused by the partial breakage and fragmentation of the brittle first network and interconnection among the fragments by the polymer chains of second network [2]. Brown [4] and Tanaka [5] have proposed similar models that can qualitatively explain the anomalously high fracture energy, assuming that the DN gel is locally damaged (yielded) around the crack tip and that the energy dissipated for damage accumulation enhances the effective fracture energy. Using AFM measurements [6] and 3D color laser microscope[7], we successfully detected the existence of softened regions, of several hundreds μm in thickness, at the crack tip just below the fracture surfaces, which supports the assumption of localized damage accumulation. A linear relationship between the thickness of the softened yielding zone and the fracture energy of the gel was observed, which is in agreement with the local yielding zone explanation.

    Karst hydrological process has largely been altered by climate change and human activity. In many places throughout the world, human activity (e.g. groundwater pumping and dewatering from mining) has intensified and surpassed climate change, where human activity becomes the primary factor that affects groundwater system. But it is still largely unclear how the human activity affects spring discharge in magnitude and periodicity. This study investigates the effects of anthropogenic activity on spring discharge, using the Xin'an Springs of China as an example. The Xin'an Spring discharge were divided into two time periods: the pre-development period from 1956 to 1971 and the post-development period from 1972 to 2013. We confirm the dividing time (i.e. 1971) of these two periods using the Wilcoxon rank-sum test. Then the wavelet transform and wavelet coherence were used to analyze the karst hydrological processes for the two periods respectively. We analyze the correlations of precipitation and the Xin'an spring discharge with the monsoons including the Indian Summer Monsoon (ISM) and the West North Pacific Monsoon (WNPM) and the climate teleconnections including El Niño Southern Oscillation (ENSO) and Pacific Decadal Oscillation (PDO), respectively. The results indicated that the spring discharge was attenuated about 19.63% under the influence of human activity in the Xin'an Springs basin. However, human activity did not alter the size of the resonance frequencies between the spring discharge and the monsoons. In contrast, it reinforced the periodicities of the monsoons-driven spring discharge. It suggested that human has adapted to the major climate periodicities, and human activity had the same rhyme with the primary climate periodicity. In return, human activity enhances the correlation between the monsoons and the spring discharge.

Here S satisfies |S(x,n,c)|7/6, which insures the global existence of bounded weak solution. Our result covers completely and improves the recent result by Wang and Cao (Discrete Contin Dyn Syst Ser B 20:3235-3254, 2015) which asserts, just in the case m=1, the global existence of solutions, but without boundedness, and that by Winkler (Calc Var Partial Differ Equ 54:3789-3828, 2015) which only involves the case of α =0 and requires the convexity of the domain.

It is proved that when {m>2-n+2/2n}, the system possesses global bounded weak solutions for any sufficiently smooth nonnegative initial data. In particular, we improved the recent result by Wang et al. (Z Angew Math Phys, 2015. doi: 10.1007/s00033-014-0491-9 ) in the sense that we established the global boundedness of weak solutions. We also removed the convexity assumption on the domain used by Wang et al. (Z Angew Math Phys 65:1137-1152, 2014, 2015).

    XinRay Systems Inc has a rectangular x-ray computed tomography (CT) imaging setup using multibeam x-ray tubes. These multibeam x-ray tubes are based on cold cathodes using carbon nanotube (CNT) field emitters. Due to their unique design, a CNT x-ray tube can contain a dense array of independently controlled electron emitters which generate a linear array of x-ray focal spots. XinRay uses a set of linear CNT x-ray tubes to design and construct a stationary CT setup which achieves sufficient CT coverage from a fixed set of views. The CT system has no moving gantry, enabling it to be enclosed in a compact rectangular tunnel. The fixed locations of the x-ray focal spots were optimized through simulations. The rectangular shape creates significant variation in path length from the focal spots to the detector for different x-ray views. The shape also results in unequal x-ray coverage in the imaged space. We discuss the impact of this variation on the reconstruction. XinRay uses an iterative reconstruction algorithm to account for this unique geometry, which is implemented on a graphics processing unit (GPU). The fixed focal spots prohibit the use of an antiscatter grid. Quantitative measure of the scatter and its impact on the reconstruction will be discussed. These results represent the first known implementation of a completely stationary CT setup using CNT x-ray emitter arrays.

  10. Scientific psychology within the Chinese language and cultural context.

    PubMed

    Shen, Heyong

    2006-01-01

    The Scientific Psychology that was founded by Wilhelm Wundt appeared in China in the late nineteenth century. The scholars translated the name of psychology into Chinese as Xin-Li-Xue, for which the meaning of the words looks like "heartology," i.e., "the study of the heart." In Chinese, the same core structure related to "heart" (Xin) is found in most of the terms of psychology, such as emotion, thinking, will, forgetting, and memory. By translating Xin as "heart" instead of "mind," we maintain an embodied approach to understanding the "principles of the heart." Through a historical approach to the influence of Western psychology, a cultural analysis of the meaning of the term psychology in Chinese, and a focus on the meeting of Eastern and Western psychology, we can witness the significance of psychology in the Chinese language and cultural context. I will use three parts to present psychology in the Chinese cultural context: the origins of Chinese psychology, from a historical approach; the meaning of "psychology" in Chinese, using a cultural analysis; and the meeting of Eastern and Western psychology, focusing on the development and future.

  11. [A discussion on influence of philosophical idea of Guan Zi on TCM].

    Guan Zi has substantial content and deep idea, being paid great attention among the various ancient schools of thought. After discussing the influence of its philosophical idea on TCM, it can be concluded that Guan Zi raised Yin Yan concept to a natural law earlier after Lao Zi first philosophized it. Meanwhile discussed the relationship between Yin and Yang systematically such as respecting Yang, Yang can control Yin, and relativity of Yin and Yang. It first setup Jing -Qi Theory, discussing materiality of the Nature and life from the sense of ontology. But it confused Jing Shen and Jing Qi, and could not weep the primitive color of Xing-Shen Monism. It emphasized on self-cultivation and embodied Xu (voidness), Yi (unity), Jing (tranquility) and Yin (cause) on preserving health.

  12. Uniform regularity estimates in homogenization theory of elliptic systems with lower order terms on the Neumann boundary problem

    NASA Astrophysics Data System (ADS)

    Xu, Qiang

    2016-10-01

    In this paper, we mainly employed the idea of the previous paper [34] to study the sharp uniform W 1 , p estimates with 1 < p ≤ ∞ for more general elliptic systems with the Neumann boundary condition on a bounded C 1 , η domain, arising in homogenization theory. Based on the skills developed by Z. Shen in [27] and by T. Suslina in [31,32], we also established the L2 convergence rates on a bounded C 1 , 1 domain and a Lipschitz domain, respectively. Here we found a "rough" version of the first order correctors (see (1.12)), which can unify the proof in [27] and [32]. It allows us to skip the corresponding convergence results on Rd that are the preconditions in [31,32]. Our results can be regarded as an extension of [23] developed by C. Kenig, F. Lin, Z. Shen, as well as of [32] investigated by T. Suslina.

    By multiple realignments of density matrices, we present a new separability criterion for the multipartite quantum state, which includes the computable cross-norm or realignment criterion and the multipartite partial realignment criterion as special cases. An example is used to show that the new criterion can be more efficient than the corresponding multipartite realignment criteria given in Horodecki et al. (Open Syst Inf Dyn 13:103-111, 2006) and Shen et al. (Phys Rev A 92:042332, 2015).

We establish uniform optimal regularity estimates for solutions of Neumann problems in a bounded Lipschitz domain with L 2 boundary data. The proof relies on a boundary Korn inequality for solutions of systems of linear elasticity and uses a large-scale Rellich estimate obtained in Shen (Anal PDE, arXiv:1505.00694v2).

  4. Multitaper Spectral Analysis and Wavelet Denoising Applied to Helioseismic Data

    NASA Technical Reports Server (NTRS)

    Komm, R. W.; Gu, Y.; Hill, F.; Stark, P. B.; Fodor, I. K.

    1999-01-01

    Estimates of solar normal mode frequencies from helioseismic observations can be improved by using Multitaper Spectral Analysis (MTSA) to estimate spectra from the time series, then using wavelet denoising of the log spectra. MTSA leads to a power spectrum estimate with reduced variance and better leakage properties than the conventional periodogram. Under the assumption of stationarity and mild regularity conditions, the log multitaper spectrum has a statistical distribution that is approximately Gaussian, so wavelet denoising is asymptotically an optimal method to reduce the noise in the estimated spectra. We find that a single m-upsilon spectrum benefits greatly from MTSA followed by wavelet denoising, and that wavelet denoising by itself can be used to improve m-averaged spectra. We compare estimates using two different 5-taper estimates (Stepian and sine tapers) and the periodogram estimate, for GONG time series at selected angular degrees l. We compare those three spectra with and without wavelet-denoising, both visually, and in terms of the mode parameters estimated from the pre-processed spectra using the GONG peak-fitting algorithm. The two multitaper estimates give equivalent results. The number of modes fitted well by the GONG algorithm is 20% to 60% larger (depending on l and the temporal frequency) when applied to the multitaper estimates than when applied to the periodogram. The estimated mode parameters (frequency, amplitude and width) are comparable for the three power spectrum estimates, except for modes with very small mode widths (a few frequency bins), where the multitaper spectra broadened the modest compared with the periodogram. We tested the influence of the number of tapers used and found that narrow modes at low n values are broadened to the extent that they can no longer be fit if the number of tapers is too large. For helioseismic time series of this length and temporal resolution, the optimal number of tapers is less than 10.

  5. A Comparison of Solar Cycle Variations in the Equatorial Rotation Rates of the Sun's Subsurface, Surface, Corona, and Sunspot Groups

    NASA Astrophysics Data System (ADS)

    Javaraiah, J.

    2013-10-01

    Using the Solar Optical Observing Network (SOON) sunspot-group data for the period 1985 - 2010, the variations in the annual mean equatorial-rotation rates of the sunspot groups are determined and compared with the known variations in the solar equatorial-rotation rates determined from the following data: i) the plasma rotation rates at 0.94R⊙,0.95R⊙,…,1.0R⊙ measured by the Global Oscillation Network Group (GONG) during the period 1995 - 2010, ii) the data on the soft-X-ray corona determined from Yohkoh/SXT full-disk images for the years 1992 - 2001, iii) the data on small bright coronal structures (SBCS) that were traced in Solar and Heliospheric Observatory (SOHO)/EIT images during the period 1998 - 2006, and iv) the Mount Wilson Doppler-velocity measurements during the period 1986 - 2007. A large portion (up to ≈ 30∘ latitude) of the mean differential-rotation profile of the sunspot groups lies between those of the internal differential-rotation rates at 0.94R⊙ and 0.98R⊙. The variation in the yearly mean equatorial-rotation rate of the sunspot groups seems to be lagging behind that of the equatorial-rotation rate determined from the GONG measurements by one to two years. The amplitude of the GONG measurements is very small. The solar-cycle variation in the equatorial-rotation rate of the solar corona closely matches that determined from the sunspot-group data. The variation in the equatorial-rotation rate determined from the Mount Wilson Doppler-velocity data closely resembles the corresponding variation in the equatorial-rotation rate determined from the sunspot-group data that included the values of the abnormal angular motions (> |3∘| day-1) of the sunspot groups. Implications of these results are pointed out.

  6. A New Multi-Wavelength Synoptic Network for Solar Physics and Space Weather

    NASA Astrophysics Data System (ADS)

    Hill, Frank; Roth, Markus; Thompson, Michael

    2013-04-01

    Continuous solar observations are important for many research topics in solar physics, such as magnetic field evolution, flare and CME characteristics, and p-mode oscillation measurements. In addition, space weather operations require constant streams of solar data as input. The deployment of a number of identical instruments around the world in a network has proven to be a very effective strategy for obtaining nearly continuous solar observations. The financial costs of a network are 1-2 orders of magnitude lower than space-based platforms; network instrumentation can be easily accessed for maintenance and upgrades; and telemetry bandwidth is readily available. Currently, there are two solar observing networks with consistent instruments: BiSON and GONG, both designed primarily for helioseismology. In addition, GONG has been augmented with continual magnetic field measurements and H-alpha imagery, with both being used for space weather operational purposes. However, GONG is now 18 years old and getting increasingly more challenging to maintain. There are also at least three scientific motivations for a multi-wavelength network: Recent advances in helioseismology have demonstrated the need for multi-wavelength observations to allow more accurate interpretation of the structure and dynamics below sunspots. Vector magnetometry would greatly benefit from multi-wavelength observations to provide height information and resolve the azimuthal ambiguity. Finally, space weather operations always need a consistent reliable source of continual solar data. This presentation will outline the scientific need for a multi-wavelength network, and discuss some concepts for the design of the instrumentation. A workshop on the topic will be held in Boulder this April.

    2015-09-01

    This study represents the benthic foraminiferal assemblages, distribution and its composition along the coastal water of Port Klang, Malaysia. A total of 60 samples were collected bimonthly between Jun 2013 and July 2013 at four sites (i.e. West Port, North Port, South Port, Telok Gong and Klang River). There were 20 genera of foraminifera identified from this study sites namely: Acupeina, Ammobaculites, Ammonia, Ammotium, Arenoparella, Asterorotalia, Bolivina, Cibicides,Discorbis, Elphidium, Haplophragmoides, Haynesina, Lagena, Miliammina, Nonion, Pseudorotalia, Quinqueloculina, Spiroloculina, Textularia and Trochammina. The foraminiferal assemblages at West Port was low in diversity (H'=0.58)compared to other sites and low in abundance (804 individuals). Stress tolerant taxa, Ammonia (317 individuals) dominated the distribution in West Port. However, in North Port, high foraminifera diversity (H'=0.67) was noted compared to West Port but lower than Telok Gong and Klang river. Foraminifera at North Port very low in abundance (213 individuals). High Ammonia-Elphidium Index (AEI) value (95) and low FORAM Index (FI=1.04) recorded at South Port indicating the sediments impacted by anthropogenic stressor and therefore the sediments were in hypoxic condition. Higher FORAM Index (F1=2.34) at North Port indicated less human induced activities in the area. There were high density of foraminifera (8918 individuals) and high AEI index value (83) with high Foram Index (F1=1.11) at Telok Gong compared to other sites except North Port. The same results were recorded at Klang River locations which covered 15 sampling stations with high abundance of Ammonia spp indicating disturbed environments. Lower abundance of Elphidium spp in contrast to Ammonia spp suggests that the sediments in all the sampling sites are in hypoxic condition and less oxygen concentrations.

    A new wind-blown-dust emissions module was recently implemented into AURAMS, a Canadian regional air quality model (Park et al., 2009; Park et al., 2007), to investigate the relative impact of wind-blown dust vs. anthropogenic fugitive dust on air quality in North America. In order to apply the wind-blown dust emissions module to the entire North American continent, a soil-grain-size-distribution map was developed using the outputs of four monthly runs of AURAMS for 2002 and available PM2.5 dust-content observations. The simulation results using the new soil-grain-size-distribution map showed that inclusion of wind-blown dust emissions is essential to predict the impact of dust aerosols on air quality in North America, especially in the western U.S.. The wind-blown dust emissions varied widely by season, whereas the anthropogenic fugitive dust emissions did not change significantly. In the spring (April), the continental monthly average emissions rate of wind-blown dust was much higher than that of anthropogenic fugitive dust. The total amount of wind-blown dust emissions in North America predicted by the model for 2002 was comparable to that of anthropogenic fugitive dust emissions. Even with the inclusion of wind-blown dust emissions, however, the model still had difficulty simulating dust concentrations. Further improvements are needed, in terms of both limitations of the wind-blown-dust emission module and uncertainties in the anthropogenic fugitive dust emissions inventories, for improved dust modelling.

    Two experimentally relevant problems can relatively easily be tackled by nonlinear MHD codes. Both problems require plasma rotation in addition to the nonlinear mode coupling and full geometry already incorporated into the codes, but no additional physics seems to be crucial. These problems discussed here are: (1) nonlinear coupling and interaction of multiple MHD modes near the B limit and (2) nonlinear coupling of the m/n = 1/1 sawtooth mode with higher n gongs and development of seed islands outside q = 1.

    We examine the timing signatures of large solar eruptions resulting in flares, CMEs and Solar Energetic Particle events. We probe solar active regions from the chromosphere through the corona, using data from space and ground-based observations, including ISOON, SDO, GONG, and GOES. Our studies include a number of flares and CMEs of mostly the M- and X-strengths as categorized by GOES. We find that the chromospheric signatures of these large eruptions occur 5-30 minutes in advance of coronal high temperature signatures. These timing measurements are then used as inputs to models and reconstruct the eruptive nature of these systems, and explore their utility in forecasts.

    The influence of spontaneous generated coherence (SGC) on the Goos-Hänchen (GH) shift in the reflected light is presented. A weak probe light is incident on a cavity containing three-level gaseous atomic medium consist of 85Rb atoms. The atom-field interaction follows electromagnetically induced transparency configuration, and the SGC modifies the dispersion and absorption properties of a system [Y. Niu and S. Gong, Phys. Rev. A 73, 053811 (2006)]. The SGC enhances the Kerr nonlinearity which leads to giant negative and positive GH shifts in the reflected light. Further, the control of negative and positive GH shifts is achieved via manipulation of probe field detuning.

    For patients with nonsmall cell lung cancer (NSCLC) receiving chemotherapy, current clinical evidence has indicated add-on benefit of Chinese herbal medicine (CHM) in improving quality of life (QoL). However, the relative performance among different CHM is unknown. The aim of this overview of systematic reviews (SRs) and network meta-analyses (NMA) is to evaluate the comparative effectiveness of different CHM. Seven electronic databases including both international databases and Chinese databases were searched. SRs focus on randomized controlled trials (RCTs) with comparison of CHM plus chemotherapy against chemotherapy alone on QoL among NSCLC patients were considered eligible. Data from RCTs were extracted for random effect pairwise meta-analyses. Pooled relative risk (RR) with 95% confidence interval (CI) was used to quantify the impact of CHM on QoL. NMA was used to explore the most effective CHM for improving QoL when used with chemotherapy. From 14 SRs, 61 RCTs (n = 4247) assessing 11 different CHM were included. Result from pairwise meta-analyses showed 6 CHM (Kang-lai-te injection, Shei-qi-fu-zheng injection, Compound ku-shen injection, Kang-ai injection, Zi-jin-long tablet, and Shen-fu injection) has significant beneficial effect on QoL among NSCLC patients when used with chemotherapy, even after adjustment for publication bias. Pooled RR varied from 1.38 (95% CI: 1.11-1.72, I2 = 0.0%, Kang-lai-te injection) to 3.36 (95% CI: 1.30-8.66, I2 = 0.0%, Zi-jin-long tablet). One trial comparing Hai-shen-su (a protein extract from Tegillarca granosa L.) plus chemotherapy with chemotherapy also demonstrated beneficial effect of combined treatment (RR = 3.13, 95% CI: 1.41-6.98). Results from NMA showed no differences on the comparative effectiveness among CHM, but Hai-shen-su plus chemotherapy has the highest probability (62.3%) of being the best option for improving QoL. Use of CHM on top of chemotherapy can significantly improve QoL in NSCLC patients. Although Hai-shen

    Diffuse nutrient loss mechanism is complicated and shows remarkably regional differences due to spatial heterogeneities of underlying surface conditions, climate and agricultural practices. Moreover, current available observations are still hard to support the identification of impact factors due to different time or space steps. In this study, an integrated water system model (HEQM) was adopted to obtain the simulated loads of diffuse components (carriers: runoff and sediment; nutrient: total nitrogen (TN) and total phosphorous (TP)) with synchronous scales. Multivariable statistical analysis approaches (Analysis of Similarity and redundancy analysis) were used to assess the regional differences, and to identify impact factors as well as their contributions. Four catchments were selected as our study areas, i.e., Xiahui and Zhangjiafen Catchments of Miyun Basin in North China, Yuliang and Tunxi Catchments of Xin'anjiang Basin in South China. Results showed that the model performances of monthly processes were very good for runoff and good for sediment, TN and TP. The annual average coefficients of all the diffuse components in Xin'anjiang Basin were much greater than those in Miyun Basin, and showed significantly regional differences. All the selected impact factors interpreted 72.87-82.16% of the regional differences of carriers, and 62.72-71.62% of those of nutrient coefficients, respectively. For individual impact factor categories, the critical category was geography, followed by land-use/cover, carriers, climate, as well as soil and agricultural practices in Miyun Basin, or agricultural practices and soil in Xin'anjiang Basin. For individual factors, the critical factors were locations for the carrier regional differences, and carriers or chemical fertilizer for the nutrient regional differences. This study is expected to promote further applications of integrated water system model and multivariable statistical analysis in the diffuse nutrient studies, and

    This paper examines several pioneering genre paintings by the important scholar painter Yun Duseo (1668-1715), with its focus on their artistic sources which have not yet been explored so far. Painted on ramie, 'Women Picking Potherbs' is one of the most intriguing examples among Yun Duseo's oeuvre, which encompasses a broad variety of themes, including genre imagery, landscapes, portraits, dragons, and horses. Even among Yun Duseo's genre paintings, 'Women Picking Potherbs' is extraordinary, as recent scholarship regards it as the earliest independent representation of lower-class women in the history of Korean art. In particular, Yun Duseo painted two women who were working ourdoors to gather spring potherbs. In a conservative Confucian society, it was extraordinary women who were working outdoors. Hence, Yun Duseo occupies a highly important place in Korean painting. Furthermore, even though Yun Duseo came from the upper-class, he often painted images of lower class people working. It is possible that Yun Duseo was familiar with the book titled "Tian gong kai wu" (Exploitation of the Works of Nature) which was published in the 17th century. By identifying the probable body of his artistic sources in the book known as "Tian gong kai wu," it will be possible to assess the innovations and limitations found in 'Women Picking Potherbs'.

  5. ABRUPT LONGITUDINAL MAGNETIC FIELD CHANGES AND ULTRAVIOLET EMISSIONS ACCOMPANYING SOLAR FLARES

    We have used Transition Region and Coronal Explorer 1600 A images and Global Oscillation Network Group (GONG) magnetograms to compare ultraviolet (UV) emissions from the chromosphere to longitudinal magnetic field changes in the photosphere during four X-class solar flares. An abrupt, significant, and persistent change in the magnetic field occurred across more than 10 pixels in the GONG magnetograms for each flare. These magnetic changes lagged the GOES flare start times in all cases, showing that they were consequences and not causes of the flares. Ultraviolet emissions were spatially coincident with the field changes. The UV emissions tended to lag the GOES start times for the flares and led the changes in the magnetic field in all pixels except one. The UV emissions led the photospheric field changes by 4 minutes on average with the longest lead being 9 minutes; however, the UV emissions continued for tens of minutes, and more than an hour in some cases, after the field changes were complete. The observations are consistent with the picture in which an Alfven wave from the field reconnection site in the corona propagates field changes outward in all directions near the onset of the impulsive phase, including downward through the chromosphere and into the photosphere, causing the photospheric field changes, whereas the chromosphere emits in the UV in the form of flare kernels, ribbons, and sequential chromospheric brightenings during all phases of the flare.

    We examined differences among the coronal magnetic field structures derived with the potential field source surface (PFSS) model for Carrington Rotation 2144, from 21 November to 19 December 2013. We used the synoptic maps of solar photospheric magnetic field from four observatories, the Huairou Solar Observing Station (HSOS), Global Oscillation Network Group (GONG), Helioseismic Magnetic Imager (HMI), and Wilcox Solar Observatory (WSO). We tested two smoothing methods, Gaussian and boxcar averaging, and correction of unbalanced net magnetic flux. The solutions of three-dimensional coronal magnetic field are significantly different each other. An open-field region derived with HSOS data agrees best with the corresponding coronal hole observed by Solar Dynamics Observatories/Atmospheric Imaging Assembly, while HMI data yielded best agreements with the near-Earth OMNI database. The GONG data overall gave agreements as good as the HMI. The PFSS calculations using WSO data were least sensitive to the choices we examined in this work. Differences in PFSS solutions using different choices and parameters in smoothing imply that the photospheric magnetic field distributions with size of several degrees at midlatitude and low-latitude regions can be decisive, at least, in the examined period. To better determine the global solar corona, therefore, further evaluation of influences from compact bipolar magnetic field is needed.

    The Helioseismic and Magnetic Imager (HMI) onboard the Solar Dynamics Observatory (SDO) provides a new tool for the systematic observation of white-light flares, including Doppler and magnetic information as well as continuum. In our initial analysis of the highly impulsive -ray flare SOL2010-06-12T00:57 (Martínez Oliveros et al., Solar Phys. 269, 269, 2011), we reported the signature of a strong blueshift in the two footpoint sources. Concerned that this might be an artifact due to aliasing peculiar to the HMI instrument, we undertook a comparative analysis of Global Oscillation Network Group (GONG++) observations of the same flare, using the PArametric Smearing Correction ALgorithm (PASCAL) algorithm to correct for artifacts caused by variations in atmospheric smearing. This analysis confirms the artifactual nature of the apparent blueshift in the HMI observations, finding weak redshifts at the footpoints instead. We describe the use of PASCAL with GONG++ observations as a complement to the SDO observations and discuss constraints imposed by the use of HMI far from its design conditions. With proper precautions, these data provide rich information on flares and transients.

    2003-05-01

    The solar oscillation parameters, as the frequency, are usually determined by fitting a theoretical profile to the observed Doppler velocity (V) power spectrum. We present here the solar oscillation parameters determined using GONG V data as well as Intensity (I) data. To do that, we used Severino et al. (2001, ApJ 561,444) model to reproduce the following 4 helioseismic spectra: V and I power spectrum, I-V phase difference and coherence spectra. This model is based on a coherent resonant p-mode signal; two coherent background components, one correlated and one uncorrelated to the oscillation modes; and, finally, the uncoherent noise. Using this model, we have fitted simultaneously the 4 helioseismic spectra mentioned above for several hundreds modes between l=15 and 50 and for 9 GONG months rotation corrected m-average data around the solar minimum. The solar oscillation parameters (frequency, amplitude and width) obtained by this way will be presented as well as a comparison with the results obtained using only V data. The study of the background components used in the model with the aim of better understanding the solar oscillation excitation mechanism will be addressed. This work is supported by NASA grant NAG5-11703.

    Self-control problems commonly manifest as temper outbursts and repetitive/rigid/impulsive behaviors, in children with autism spectrum disorders (ASD), which often contributes to learning difficulties and caregiver burden. The present study aims to compare the effect of a traditional Chinese Chan-based mind-body exercise, Nei Yang Gong, with that of the conventional Progressive Muscle Relaxation (PMR) technique in enhancing the self-control of children with ASD. Forty-six age- and IQ-matched ASD children were randomly assigned to receive group training in Nei Yang Gong (experimental group) or PMR (control group) twice per week for four weeks. The participants’ self-control was measured by three neuropsychological tests and parental rating on standardized questionnaires, and the underlying neural mechanism was assessed by the participants’ brain EEG activity during an inhibitory-control task before and after intervention. The results show that the experimental group demonstrated significantly greater improvement in self-control than the control group, which concurs with the parental reports of reduced autistic symptoms and increased control of temper and behaviors. In addition, the experimental group showed enhanced EEG activity in the anterior cingulate cortex, a region that mediates self-control, whereas the PMR group did not. The present findings support the potential application of Chinese Chan-based mind-body exercises as a form of neuropsychological rehabilitation for patients with self-control problems.

    Longitudinal magnetograms obtained with thc SOLIS Vector Spectromagnetograph (VSM) during a cross-calibration period are compared with similar data from the NASA/NSO Spectromagnetograph (SPM) at the NSO/Kitt Peak Vacuum Telescope as well as with SOHO/MDI and GONG magnetogram. The VSM began observation at the University of Arizona agricultural test site and collaborative observations were obtained with both the VSM and SPM from 2003 Aug 05 through 2003 Sep 21 where the SPM was officially retired. The VSM replaces the SPM and continues the 3O-year NSO/Kitt Peak synoptic magnetogram record. Magnetograms are compared by equating histograms and, for selected examples, by pixel-by-pixel comparison of co-registered images. The VSM was not corrected for polarization crosstalk and was operated without hast guiding. Solar activity was at best moderate during this period. Over the range of observed fields, the VSM magnetograms show greatly improved sensitivity but are otherwise virtually identical with "raw" SPM magnetogram. GONG magnetograms are also closely comparable with the SPM while MDI flux values tend to be stronger by a factor of 1.2 - 1.4. Dependence of the results on seeing will be discussed. Partial funding for this work was provided through Solar and Heliospheric Research Supporting Research and Technology grants from NASA's Office of Space Sciences.

    The precipitation in the forecast period influences flood forecasting precision, due to the uncertainty of the input to the hydrological model. Taking the ZhangHe basin as the example, the research adopts the precipitation forecast and ensemble precipitation forecast product of the AREM model, uses the Xin Anjiang hydrological model, and tests the flood forecasts. The results show that the flood forecast result can be clearly improved when considering precipitation during the forecast period. Hydrological forecast based on Ensemble Precipitation prediction gives better hydrological forecast information, better satisfying the need for risk information for flood prevention and disaster reduction, and has broad development opportunities.

  4. Fast Multigrid Techniques in Total Variation-Based Image Reconstruction

    NASA Technical Reports Server (NTRS)

    Oman, Mary Ellen

    1996-01-01

    Existing multigrid techniques are used to effect an efficient method for reconstructing an image from noisy, blurred data. Total Variation minimization yields a nonlinear integro-differential equation which, when discretized using cell-centered finite differences, yields a full matrix equation. A fixed point iteration is applied with the intermediate matrix equations solved via a preconditioned conjugate gradient method which utilizes multi-level quadrature (due to Brandt and Lubrecht) to apply the integral operator and a multigrid scheme (due to Ewing and Shen) to invert the differential operator. With effective preconditioning, the method presented seems to require Omicron(n) operations. Numerical results are given for a two-dimensional example.

    Total variation (TV) methods are very effective for recovering ``blocky,`` possibly discontinuous, images from noisy data. A fixed point algorithm for minimizing a TV-penalized least squares functional is presented and compared with existing minimization schemes. A variant of the cell-centered finite difference multigrid method of Ewing and Shen is implemented for solving the (large, sparse) linear subproblems. Numerical results are presented for one- and two-dimensional examples; in particular, the algorithm is applied to actual data obtained from confocal microscopy.

  6. Effects of comprehensive therapy based on traditional Chinese medicine patterns in stable chronic obstructive pulmonary disease: a four-center, open-label, randomized, controlled study

    2012-01-01

    Background Traditional Chinese medicine (TCM) has been used to treat chronic obstructive pulmonary disease (COPD) for many years. This study aimed to evaluate the efficacy and safety of the comprehensive therapy based on the three common TCM patterns in stable COPD patients. Methods A four-center, open-label randomized controlled method was conducted. A total of 352 patients were divided into the trial group (n = 176, treated with conventional Western medicine and Bu-Fei Jian-Pi granules, Bu-Fei Yi-Shen granules, and Yi-Qi Zi-Shen granules based on the TCM patterns respectively) and the control group (n = 176, treated with conventional Western medicine). The frequency and duration of acute exacerbation, lung function, clinical symptoms, 6-minute walking distance (6MWD), dyspnea scale and quality of life were observed during a 6-month treatment period and at a further 12-month follow-up. Results A total of 306 patients completed the study fully. The full analysis set (FAS) population was 350 and the per-protocol analysis set (PPS) population was 306. After the 6-month treatment and 12-month follow-up, there were significant differences between the trial and control group in the following: frequency of acute exacerbation (FAS: P = 0.000; PPS: P = 0.000); duration of acute exacerbation (FAS: P = 0.000; PPS: P = 0.001); FEV1 (FAS: P = 0.007; PPS: P = 0.008); symptoms (FAS: P = 0.001; PPS: P = 0.001); 6MWD (FAS: P = 0.045; PPS: P = 0.042); dyspnea scale (FAS: P = 0.002; PPS: P = 0.004); and physical domain (FAS: P = 0.000; PPS: P = 0.000), psychological domain (FAS: P = 0.008; PPS: P = 0.011), social domain (FAS: P = 0.001; PPS: P = 0.000) and environment domain (FAS: P = 0.015; PPS: P = 0.009) of the WHOQOL-BREF questionnaire. There were no differences between the trial and control group in FVC, FEV1% and adverse events. Conclusions Based on the TCM patterns, Bu-Fei Jian-Pi granules, Bu-Fei Yi-Shen granules and Yi-Qi Zi-Shen granules have beneficial effects on measured

    2003-10-01

    A detailed modeling analysis is conducted focusing on nonmethane hydrocarbons and ozone in three southeast United States national parks for a 15-day time period (14-29 July 1995) characterized by high O3 surface concentrations. The three national parks are Smoky Mountains National Park (GRSM), Mammoth Cave National Park (MACA), and Shenandoah National Park (SHEN), Big Meadows. A base emission scenario and eight variant predictions are analyzed, and predictions are compared with data observed at the three locations for the same time period. Model-predicted concentrations are higher than observed values for O3 (with a cutoff of 40 ppbv) by 3.0% at GRSM, 19.1% at MACA, and 9.0% at SHEN (mean normalized bias error). They are very similar to observations for overall mean ozone concentrations at GRSM and SHEN. They generally agree (the same order of magnitude) with observed values for lumped paraffin compounds but are an order of magnitude lower for other species (isoprene, ethene, surrogate olefin, surrogate toluene, and surrogate xylene). Model sensitivity analyses here indicate that each location differs in terms of volatile organic compound (VOC) capacity to produce O3, but a maximum VOC capacity point (MVCP) exists at all locations that changes the influence of VOCs on O3 from net production to production suppression. Analysis of individual model processes shows that more than 50% of daytime O3 concentrations at the high-elevation rural locations (GRSM and SHEN) are transported from other areas; local chemistry is the second largest O3 contributor. At the low-elevation location (MACA), about 80% of daytime O3 is produced by local chemistry and 20% is transported from other areas. Local emissions (67-95%) are predominantly responsible for VOCs at all locations, the rest coming from transport. Chemistry processes are responsible for about 50% removal of VOCs for all locations; less than 10% are lost to surface deposition and the rest are exported to other areas

We demonstrate, in contrast to the work of Shen et al., that the chemical reactivity between LiOH and the triiodide ion (I3 (-)) to form IO3 (-) indicates that LiOH can be removed on charging; the electrodes do not clog, even after multiple cycles, confirming that solid products are reversibly removed.

    A gas attenuator is an important element of the LCLS facility. The attenuator must operate in a broad range of x-ray energies, provide attenuation coefficient between 1 and 10{sup 4} with the accuracy of 1% and, at the same time, be reliable and allow for many months of un-interrupted operation. S. Shen has recently carried out a detailed design study of the attenuator based on the use of nitrogen as a working gas. In this note we assess the features of the attenuator based on the use of argon. We concentrate on the physics issues, not the design features.

    The Yun - qi theory is closely related to the calendar system. In Chinese history, the change of the calendar system by Adam Schall von Bell in early Qing Dynasty was a disputable event. Studying its effect on Yun - qi theory, we find out the issue of changing the order of Zi and Shen lunar mansions, which annoyed many Chinese astronomers and scholars, had no significant influence on Yun - qi theory. As for the new calculation system of clepsydra and solar terms, these changes increased the accuracy of the Yun - qi calendar.

    Shock-wave experiments on iron preheated to 1,573 K conducted from 14 to 73 GPa, yield new data for sound velocities of the {gamma}- and liquid-phases. Melting was observed in the highest pressure ({approximately} 71 {+-} 2 GPa) experiments at calculated shock temperatures of 2,775 {+-} 160 K. This single crossing of the {gamma}-liquid boundary measured here agrees closely with the {gamma}-iron melting line determined by Boehler [1993], Saxena et al. [1993], and Jephcoat and Besedin [1997]. This {gamma}-iron melting curve is {approximately} 300 C lower than that of Shen et al. [1998b] at 80 GPa.

    Auricular acupuncture using the National Acupuncture Detoxification Association (NADA) protocol stimulates 5 points in each ear--the Shen Men, sympathetic nervous system, liver, kidney, and lung. This protocol is also known as Acu Detox, and has been used for recovery in community-based settings and drug use treatment programs. It has also been proven to be effective in alleviating stress and enhancing a general sense of well-being. This article describes the auricular acupuncture and acupressure program developed for a university setting and its use as a tool to enhance harm reduction and mental health services.

    By means of concentration cells of the following type: Mg(s)∣MgCl2 in (LiCl-KCl)eut( l)∣Mg-In or Mg-ln-Cd( l), the partial thermodynamic data of Mg in Mg-ln and Mg-ln-Cd liquid solutions have been obtained in the composition range 0.1 ≤ XMg ≤ 0.7 for binary while for ternary alloys for t = 0.4, 0.6, and 0.8 (where t = XIn/(XIn + XCd)) and at various mangesium concentrations 0.1≤ XMg ≤ 0.6. Both ternary and binary alloys were investigated at a temperature range 750 to 900 K. Experimental partial excess Gibbs energies of Mg were interpreted by the Pelton and Flengas method. Results for Mg-ln system show a slight difference in comparison with previously published data for the same system also from emf studies. Results of this study for Mg-ln system exhibit negative and positive excess entropies of magnesium and the same is observed in ternary system Mg-ln-Cd at the range of concentration close to Mg-ln.

    Temperature-dependent material parameters and device performances of Ga xIn 1-xAs 1-ySb y TPV cells applied in low temperature (800-1200 °C) radiators are simulated using the PC-1D. As is well known, the optimum bandgap ( E g) decreases towards lower radiator temperatures. So far, the lowest achievable E g of Ga xIn 1-xAs 1-ySb y at 300 K is 0.5 eV. We mainly considering the Ga 0.8In 0.2As 0.18Sb 0.82 ( E g = 0.5 eV) TPV cell. The effects of doping concentration and recombination mechanisms of the emitter layer on photovoltaic conversion efficiencies ( η cel) are analyzed in detail, and η cel can be improved by optimizing doping concentration and suppressing carrier recombination. The effects of GaSb window layer on η cel are also presented. It shows the type-II energy-band alignment GaSb(window)/GaInAsSb(emitter) heterostructure affect η cel mainly through V oc. For the first time, the effects of operating temperatures on device performances are analyzed based on temperature-dependent material parameters, and the temperature coefficients of the device performances are presented.

    Coptidis Rhizoma, Scutellariae Radix, and Rhei Rhizoma are three common Chinese herbs. There are many herbal formulas which contain either two or all three of the herbs mentioned above. Their bioactive components have already been identified, respectively. However, there is no report about separation of the 13 bioactive constituents of the three herbs at the same time. In order to assess these constituents of related Chinese herbal preparations, a micellar electrokinetic chromatography method was developed. While buffer pH and surfactant concentration affected the resolution of separation, acetonitrile percentage was found to significantly influence the resolution, peak shape, and elution window. Optimum separation of 13 compounds was achieved at pH 7.3 using a buffer mixture of 70% (v/v) 3 mM di-sodium tetraborate, 10 mM sodium dihydrogen phosphate, and 50 mM sodium deoxycholate with 30% (v/v) acetonitrile. When applying the developed method to analyze a model preparation, San-huang-xie-xin-tang, which contains all three herbs, 8 of the 13 bioactive constituents, could be determined. The present study proposed a method to assess San-huang-xie-xin-tang within short analysis time and also provided a possible starting point to evaluate related herbal preparations containing Coptidis Rhizoma, Scutellariae Radix, and Rhei Rhizoma.

    This paper is dedicated to studying the following Schrödinger-Poisson system -triangle u+V(x)u+λφ u=K(x)f(u),& quad xin R3,-triangleφ= u^2,quad xin R3, where V, K are positive continuous potentials, f is a continuous function and {λ} is a positive parameter. We develop a direct approach to establish the existence of one ground state sign-changing solution {u_λ} with precisely two nodal domains, by introducing a weaker condition that there exists {θ_0in (0,1)} such that K(x)[f(τ)/τ^3-f(tτ)/(tτ)^3 ]sign(1-t)+θ_0V(x)|1-t^2|/(tτ)^2 ≥ 0, quad forall x in R^3, t > 0, τ≠ 0 than the usual increasing condition on {f(t)/|t|^3}. Under the above condition, we also prove that the energy of any sign-changing solution is strictly larger than two times the least energy, and give a convergence property of {u_λ} as {λsearrow 0}.

    We study conditions on a set M in a Banach space X which are necessary or sufficient for the set R(M) of all sums x_1+\\dots+x_n, x_k\\in M, to be dense in X. We distinguish conditions under which the closure \\overline{R(M)} is an additive subgroup of X, and conditions under which this additive subgroup is dense in X. In particular, we prove that if M is a closed rectifiable curve in a uniformly convex and uniformly smooth Banach space X, and does not lie in a closed half-space \\{x\\in X\\colon f(x)≥0\\}, f\\in X^*, and is minimal in the sense that every proper subarc of M lies in an open half-space \\{x\\in X\\colon f(x)>0\\}, then \\overline{R(M)}=X. We apply our results to questions of approximation in various function spaces.

    Photoluminescence wavelength emission of Ga xIn 1-xAs yP 1-y/InP heterostructures grown in multiwafer gas-source molecular-beam epitaxy (GSMBE) is studied in detail for both bulk and multiple quantum well (MQWs) heterostructures. Excellent photoluminescence wavelength uniformity is reported in 4×2-in. configuration, demonstrating the compatibility of GSMBE process with large-scale 1.55 μm telecom laser production. A strong dependence of wavelength uniformity on group-V/group-III flux ratio is reported and analyzed quantitatively. An empirical model based on the interplay between group-V elements incorporation and gas distribution is proposed to predict the influence of AsH 3 and PH 3 fluxes on As content in the solid. This understanding opens the way to an accurate tuning of wavelength dispersion of Ga xIn 1-xAs yP 1-y/InP MQWs grown in multiwafer GSMBE system.

    A major flare (of class X3.4) occurred on 2006 December 13 in the active region NOAA 10930. This flare event has remained interesting to solar researchers for studies related to particle acceleration during the flare process and the reconfiguration of magnetic fields as well as fine-scale features in the active region. The energy released during flares is also known to induce acoustic oscillations in the Sun. Here, we analyze the line-of-sight velocity patterns in this active region during the X3.4 flare using the Dopplergrams obtained by the Global Oscillation Network Group (GONG) instrument. We have also analyzed the disk-integrated velocity observations of the Sun obtained by the Global Oscillation at Low Frequency (GOLF) instrument on board the Solar and Heliospheric Observatory spacecraft as well as full-disk collapsed velocity signals from GONG observations during this flare to study any possible connection between the flare-related changes seen in the local and global velocity oscillations in the Sun. We apply wavelet transform to the time series of the localized velocity oscillations as well as the global velocity oscillations in the Sun spanning the flare event. The line-of-sight velocity shows significant enhancement in some localized regions of the penumbra of this active region during the flare. The affected region is seen to be away from the locations of the flare ribbons and the hard X-ray footpoints. The sudden enhancement of this velocity seems to be caused by the Lorentz force driven by the 'magnetic jerk' in the localized penumbral region. Application of wavelet analysis to these flare-induced localized seismic signals shows significant enhancement in the high-frequency domain (5 <{nu} < 8 mHz) and a feeble enhancement in the p-mode oscillations (2 <{nu} < 5 mHz) during the flare. On the other hand, the wavelet analysis of GOLF velocity data and the full-disk collapsed GONG velocity data spanning the flare event indicates significant post

  13. Characteristic Fracture Spacing in Primary and Secondary Recovery from Naturally Fractured Reservoirs

    NASA Astrophysics Data System (ADS)

    Gong, J.; Rossen, W.

    2015-12-01

    We showed previously (Gong and Rossen, 2014a,b) that, if the fracture aperture distribution is broad enough in a naturally fractured reservoir, even one where the fracture network is well-connected, most fractures can be eliminated without significantly affecting the flow through the fracture network. During a waterflood or enhanced-oil-recovery (EOR) process, the production of oil depends on the supply of injected water or EOR agent. This suggests that the characteristic fracture spacing for the dual-porosity/dual-permeability simulation of waterflood or EOR in a naturally fractured reservoir should account not for all fractures but only the relatively small portion of the fracture network carrying almost all the injected water or EOR agent. In contrast, in primary production even a relatively small fracture represents an effective path for oil to flow to a production well. Thus in primary production the effective fracture spacing should include all the fractures. This distinction means that the "shape factor" in dual-porosity/dual-permeability reservoir simulators and the repeating unit in homogenization should depend on the process involved: specifically, it should be different for primary and secondary or tertiary recovery. We test this hypothesis in a simple representation of a fractured reservoir with a non-uniform distribution of fracture flow conductivities. We compare oil production, flow patterns in matrix, and the pattern of oil recovery around fractures with and without the "unimportant" fractures present. In primary production, all fractures which are much more permeable than matrix play a significant role in production. The shape factor or repeating-unit size should reflect the entire fracture distribution. In secondary or tertiary production, the role of fractures that carry relatively little flow depends on injection rate, the ratio of flow carried by the different fractures, and the permeability of matrix. In some cases, the appropriate shape

  14. THE DEPENDENCE OF THE NEUTRINO MECHANISM OF CORE-COLLAPSE SUPERNOVAE ON THE EQUATION OF STATE

    Couch, Sean M.

    2013-03-01

    We study the dependence of the delayed neutrino-heating mechanism for core-collapse supernovae on the equation of state (EOS). Using a simplified treatment of the neutrino physics with a parameterized neutrino luminosity, we explore the relationship between explosion time, mass accretion rate, and neutrino luminosity for a 15 M {sub Sun} progenitor in 1D and 2D. We test the EOS most commonly used in core-collapse simulations: the models of Lattimer and Swesty and the model of Shen et al. We find that for a given neutrino luminosity, 'stiffer' EOS, where stiffness is determined by a combination of nuclear matter properties not just incompressibility, K, explode later than 'softer' EOS. The EOS of Shen et al., being the stiffest EOS, by virtue of larger incompressibility and symmetry energy slope, L, explodes later than any of the Lattimer and Swesty EOS models. Amongst the Lattimer and Swesty EOS that all share the same value of L, the explosion time increases with increasing nuclear incompressibility, K. We find that this holds in both 1D and 2D, while for all of the models, explosions are obtained more easily in 2D than in 1D. We argue that this EOS dependence is due in part to a greater amount of acoustic flux from denser proto-neutron star atmospheres that result from a softer EOS. We also discuss the relevance of approximate instability criteria to realistic simulations.

    Blade element moment (BEM) is a widely used technique for prediction of wind turbine aerodynamics performance, the reliability of airfoil data is an important factor to improve the prediction accuracy of aerodynamic loads and power using a BEM code. The method of determination of angle of attack on rotor blades developed by SHEN, et al is successfully used to extract airfoil data from experimental characteristics on the MEXICO (Model experiments in controlled conditions) rotor. Detailed surface pressure and particle image velocimetry (PIV) flow fields at different rotor azimuth positions are examined to determine the sectional airfoil data. The present technique uses simultaneously both PIV data and blade pressure data that include the actual flow conditions (for example, tunnel effects), therefore it is more advantageous than other techniques which only use the blade loading (pressure data). The extracted airfoil data are put into a BEM code, and the calculated axial and tangential forces are compared to both computations using BEM with Glauert's and SHEN's tip loss correction models and experimental data. The comparisons show that the present method of determination of angle of attack is correct, and the re-calculated forces have good agreements with the experiment.

    A heptamethyltrisiloxane liquid crystal (LC) exhibiting I -Sm A*-Sm C* phases has been characterized by calorimetry, polarizing microscopy, x-ray diffraction, electro-optics, and dielectric spectroscopy. Observations of a large electroclinic effect, a large increase in the birefringence (Δ n ) with electric field, a low shrinkage in the layer thickness (˜1.75%) at 20 °C below the Sm A*-Sm C* transition, and low values of the reduction factor (˜0.40) suggest that the Sm A* phase in this material is of the de Vries type. The reduction factor is a measure of the layer shrinkage in the Sm C* phase and it should be zero for an ideal de Vries. Moreover, a decrease in the magnitude of Δ n with decreasing temperature indicates the presence of the temperature-dependent tilt angle in the Sm A* phase. The electro-optic behavior is explained by the generalized Langevin-Debye model as given by Shen et al. [Y. Shen et al., Phys. Rev. E 88, 062504 (2013), 10.1103/PhysRevE.88.062504]. The soft-mode dielectric relaxation strength shows a critical behavior when the system goes from the Sm A* to the Sm C* phase.

  17. Herbal supplements and therapeutic drug monitoring: focus on digoxin immunoassays and interactions with St. John's wort.

    Herbal supplements can affect concentrations of therapeutic drugs measured in biological fluids by different mechanisms. Herbal products can either directly interfere with the methodology used in the measurement of drugs or indirectly interfere by altering the pharmacokinetics of coadministered drugs. The active components of Chan Su, Lu-Shen-Wan, Dan Shen, Asian and Siberian ginseng, oleander containing supplements, and Ashwagandha interfere with digoxin measurements by immunoassays, especially the polyclonal antibody-based immunoassays. Herbal supplements are sometimes contaminated with Western drugs causing drug toxicity. A therapeutic drug monitoring (TDM) service is very helpful for diagnosis of drug toxicity in such patients. Herbal products such as St. John's wort, a popular herbal antidepressant, increase the clearance of certain drugs either by increasing the activity of liver or intestinal cytochrome P-450 mixed-function oxidase or through modulation of the P-glycoprotein efflux pump. Significantly reduced concentrations of various therapeutic drugs such as digoxin, theophylline, cyclosporine, tacrolimus, tricyclic antidepressants, warfarin, and protease inhibitors can be observed due to interaction of these drugs with St. John's wort, causing treatment failure. On the other hand, a few drugs such as carbamazepine, mycophenolic acid, and procainamide do not show any interaction with St. John's wort. Understanding the effect of herbal products on TDM methodologies and identification of interactions between herbal products and drugs by TDM are very important clinically.

    Degradation of electronic devices by hot electrons is universally attributed to the generation of defects, but the mechanisms for defect generation and the specific nature of the pertinent defects are not known for most systems. Here we describe three recent case studies [1] in III-V high-electron-mobility transistors that illustrate the power of combining density functional calculations and experimental data to identify the pertinent defects and associated degradation mechanisms. In all cases, benign pre-existing defects are either depassivated (irreversible degradation) or transformed to a metastable state (reversible degradation).

    We report separate experimental and theoretical studies of the equilibration of highly excited LiH (v = 10; J = 2) in H2 at 680 K. Experiments that follow the time evolution of state-to-state population transfer in multi-collision conditions with μs resolution were carried out by Shen and co-workers at Xinjiang University and East China Institute of Science and Technology. At the same time, theoretical computations on the relaxation of this gas mixture were undertaken by McCaffery and co-workers at Sussex University. Rapid, near-resonant, vibration-vibration energy exchange is a marked feature of the initial relaxation process. However, at later stages of ensemble evolution, slower vibration-rotation transfer forms the dominant relaxation mechanism. The physics of the decay process are complex and, as demonstrated experimentally here, a single exponential expression is unlikely to capture the form of this decay with any accuracy. When these separate studies were complete, the evolution of modal temperatures from the Sussex calculations was compared with experimental measurements of these same quantities from Shanghai and Urumqi. The two sets of data were marked by their near identity, within experimental and computational error, representing an experimental validation of the theoretical/computational model developed by the Sussex group and a significant experimental advancement by the group of Shen et al.

  20. Efficient multi-dimensional solution of PDEs using Chebyshev spectral methods

    NASA Astrophysics Data System (ADS)

    Julien, Keith; Watson, Mike

    2009-03-01

    A robust methodology is presented for efficiently solving partial differential equations using Chebyshev spectral techniques. It is well known that differential equations in one dimension can be solved efficiently with Chebyshev discretizations, O( N) operations for N unknowns, however this efficiency is lost in higher dimensions due to the coupling between modes. This paper presents the "quasi-inverse" technique (QIT), which combines optimizations of one-dimensional spectral differentiation matrices with Kronecker matrix products to build efficient multi-dimensional operators. This strategy results in O( N2 D-1 ) operations for ND unknowns, independent of the form of the differential operators. QIT is compared to the matrix diagonalization technique (MDT) of Haidvogel and Zang [D.B. Haidvogel, T. Zang, The accurate solution of Poisson's equation by expansion in Chebyshev polynomials, J. Comput. Phys. 30 (1979) 167-180] and Shen [J. Shen, Efficient spectral-Galerkin method. II. Direct solvers of second- and fourth-order equations using Chebyshev polynomials, SIAM J. Sci. Comp. 16 (1) (1995) 74-87]. While the cost for MDT and QIT are the same in two dimensions, there are significant differences. MDT utilizes an eigenvalue/eigenvector decomposition and can only be used for relatively simple differential equations. QIT is based upon intrinsic properties of the Chebyshev polynomials and is adaptable to linear PDEs with constant coefficients in simple domains. We present results for a standard suite of test problems, and discuss of the adaptability of QIT to more complicated problems.

    We describe recent progress of the EOS tables for numerical simulations of core-collapse supernovae and related astrophysical phenomena. Based on the Shen EOS table, which has been widely used in supernova simulations, there is systematic progress by extending the degrees of freedom such as hyperons and quarks. These extended EOS tables have been used, for example, to study the neutrino bursts from the gravitational collapse of massive stars leading to the black hole formation. Observations of such neutrinos from galactic events in future will provide us with the information on the EOS. Recently, studies of the supernova EOS with the multi-composition of nuclei under the nuclear statistical equilibrium have been made beyond the single nucleus approximation as used in the Shen EOS. It has been found that light elements including deuterons are abundant in wide regions of the supernova cores. We discuss that neutrino-deuteron reactions may have a possible influence on the explosion mechanism through modifications of neutrino heating rates.

    Background. Chinese herbal products (CHPs) given as a therapy for symptom relief have gained widespread popularity among women with breast cancer. The aim of this study was to analyze the utilization of CHP among women with breast cancer in Taiwan. Methods. The usage, frequency of services, and CHP prescribed for breast cancer among women with breast cancer were evaluated, recruited from a randomly sampled cohort of 1,000,000 beneficiaries from the National Health Insurance Research Database. The logistic regression method was employed to estimate the odds ratios (ORs) for utilization of CHP. Results. 81.5 percent (N = 2, 236) of women with breast cancer utilized traditional Chinese medicine (TCM) and 18% of them sought TCM with the intent of treating their breast cancer. Jia-wei-xiao-yao-san (Augmented Rambling Powder) was the most frequently prescribed formula for treating breast cancer. Among the top 10 most frequently prescribed CHP for treating breast cancer, seven contained dang qui (Angelica sinensis-radix) and six contained ren shen (Panax ginseng-radix), which are reported to have potential beneficial synergistic effects on breast cancer cells. Conclusion. CHP containing dang qui (Angelica sinensis-radix) or ren shen (Panax ginseng-radix) are the most frequently prescribed for breast cancer and their effects should be taken into account by healthcare providers.

    A 3-year-old Thoroughbred filly was referred to the Equine Hospital, Korea Racing Association for evaluation of hematuria, inappetite, weight loss and depression. From 25 days prior to admission, the horse was treated for right carpal lameness with 20 mg intramuscular administration of triamcinolone acetonide per day for consecutive 10 days by a local veterinarian. Clinical and laboratory findings included vaginal hyperemia, flare in bladder wall, neutrophilia, lymphopenia, polyuria, polydipsia and laminitis in the end. High activities of aspartate transaminase and gamma glutamyltransferase and high concentration of total bilirubin indicated hepatopathy. Further hematology, serum biochemistry and urinalysis did not reveal any abnormalities. Medical history, physical and clinicopathologic findings suggest that the laminitis and hepatopathy in this horse were most likely induced by repeated administration of exogenous corticosteroid. However, guarded prognosis of treating laminitis undermined the benefit of improvement of hematuria following electroacupuncture stimulation. The combined stimulation of kidney related acupoints (Shen Peng, Shen Shu), lumber related acupoints (Yao Qian, Yao Zhong) and associate acupoints (Guan Yuan Shu, Bai Hui) at 5Hz, 1-2V, for 40 minutes was of value in the treatment of hematuria. This case shows that horses under steroids may exhibit laminitis and steroid hepatopathy. Early recognition and good management of laminitis are important in the limitation of complications.

In previous efforts in the multiscale analysis of tropical waves , the Ensemble Empirical Mode Decomposition (EEMD) has been successfully parallelized and used to detect atmospheric wave signals on different spatial scales (e.g. Shen et al., 2013b) that include Mixed Rossby Gravity (MRG) waves, Western Wind Belt (WWB), African Easterly Waves (AEWs), etc. We now extend the related studies to examine the evolution of the large scale waves and their association with the formation of tropical cyclones in the Atlantic for an extensive time period spanning multiple years. Our goal is to analyze the multiscale interaction in the initiation and early intensification stage of an AEW and its subsequent impact on TC genesis that involves mainly the large scale downscaling processes. Specific focus is on the impact of barotropic instability and critical level (CL, or steering level) that may appear in association with the AEW. The presence of the CL is believed to play an important role in providing a favorable environment in the early TC-genesis stage in the marsupial paradigm scenario. Preliminary analysis of the satellite data obtained from the newly launched Global Precipitation Measurement (GPM) mission linked to the TC genesis processes will be included.

    The genus Quasipaa (Family Dicroglossidae) is currently composed of 11 species distributed in China and Southeast Asia: Quasipaa acanthophora (Dubois & Ohler 2009), Q. boulengeri (Günther 1889), Q. courtoisi (Angel 1922), Q. delacouri (Angel 1928), Q. exilispinosa (Liu & Hu, 1975), Q. fasciculispina (Inger 1970), Q. jiulongensis (Huang & Liu, 1985), Q. shini (Ahl 1930), Q. spinosa (David 1875), Q. verrucospinosa (Bourret 1937), Q. yei (Chen, Qu & Jiang 2002) (Frost 2016). These species are morphologically similar, and their taxonomy is subject to controversy (Che et al. 2009). Analyses of nuclear and mitochondrial genes suggest the genus likely encompass additional cryptic species (Ye et al. 2013). Bioacoustics has contributed to studies on the taxonomy of the genus (Ye et al. 2013; Shen et al. 2015), however, to date, only the advertisement calls of Q. spinosa are known (Yu & Zheng 2009; Chen et al. 2012; Shen et al. 2015). Here, we describe the advertisement calls of Q. shini, which inhabits streams in the southern part of central China(Guizhou, Hunan, Guangxi and Jiangxi) and is characterized by the presence of keratinized skin spines on the lateral surfaces of the body.

    Traditional Chinese Medicine (TCM) with its focus on herbal use became popular worldwide. Treatment was perceived as safe, with neglect of rare adverse reactions including liver injury. To compile worldwide cases of liver injury by herbal TCM, we undertook a selective literature search in the PubMed database and searched for the items Traditional Chinese Medicine, TCM, Traditional Asian Medicine, and Traditional Oriental Medicine, also combined with the terms herbal hepatotoxicity or herb induced liver injury. The search focused primarily on English-language case reports, case series, and clinical reviews. We identified reported hepatotoxicity cases in 77 relevant publications with 57 different herbs and herbal mixtures of TCM, which were further analyzed for causality by the Council for International Organizations of Medical Sciences (CIOMS) scale, positive reexposure test results, or both. Causality was established for 28/57 different herbs or herbal mixtures, Bai Xian Pi, Bo He, Ci Wu Jia, Chuan Lian Zi, Da Huang, Gan Cao, Ge Gen, Ho Shou Wu, Huang Qin, Hwang Geun Cho, Ji Gu Cao, Ji Xue Cao, Jin Bu Huan, Jue Ming Zi, Jiguja, Kudzu, Ling Yang Qing Fei Keli, Lu Cha, Rhen Shen, Ma Huang, Shou Wu Pian, Shan Chi, Shen Min, Syo Saiko To, Xiao Chai Hu Tang, Yin Chen Hao, Zexie, and Zhen Chu Cao. In conclusion, this compilation of liver injury cases establishes causality for 28/57 different TCM herbs and herbal mixtures, aiding diagnosis for physicians who care for patients with liver disease possibly related to herbal TCM.

    Objectives. To apply modern text-mining methods to identify candidate herbs and formulae for the treatment of diabetic nephropathy. Methods. The method we developed includes three steps: (1) identification of candidate ancient terms; (2) systemic search and assessment of medical records written in classical Chinese; (3) preliminary evaluation of the effect and safety of candidates. Results. Ancient terms Xia Xiao, Shen Xiao, and Xiao Shen were determined as the most likely to correspond with diabetic nephropathy and used in text mining. A total of 80 Chinese formulae for treating conditions congruent with diabetic nephropathy recorded in medical books from Tang Dynasty to Qing Dynasty were collected. Sao si tang (also called Reeling Silk Decoction) was chosen to show the process of preliminary evaluation of the candidates. It had promising potential for development as new agent for the treatment of diabetic nephropathy. However, further investigations about the safety to patients with renal insufficiency are still needed. Conclusions. The methods developed in this study offer a targeted approach to identifying traditional herbs and/or formulae as candidates for further investigation in the search for new drugs for modern disease. However, more effort is still required to improve our techniques, especially with regard to compound formulae.

  10. Variational Study of the Supernova Equation of State with Hyperons

    NASA Astrophysics Data System (ADS)

    Togashi, Hajime; Hiyama, Emiko; Takano, Masatoshi

    We report on a new equation of state (EOS) of nuclear matter containing Λ hyperons constructed with the variational many-body theory for core-collapse supernova simulations. Bare baryon interactions, including the Argonne v18 two-nucleon and Urbana IX three-nucleon potentials are adopted, and the energy per baryon at zero temperature is calculated with the cluster variational method. The free energy per baryon at finite temperature is calculated with an extension of the variational method proposed by Schmidt and Pandharipande. The resulting thermodynamic quantities of hyperonic nuclear matter for various densities, temperatures, and proton fractions under the equilibrium condition μ n = μ Λ are reasonable as compared with those of the Shen EOS. It is also observed that the fraction of Λ hyperons in hot dense matter increases as the proton fraction decreases or the temperature increases. Furthermore, due to the smaller symmetry energy with our EOS, the Λ fraction of our EOS for neutron-rich matter is less than that of the Shen EOS.

    We start with the SDSS DR7 quasar catalog (Schneider et al. 2010AJ....139.2360S, Cat. VII/260), adopting the spectral measurements of Shen et al. (2011, J/ApJS/194/45). Among the SDSS DR7 quasars, 20,774 are at z < 0.83, where SDSS spectra cover Hβ and [O III] λλ4959, 5007 (hereafter [O III] for short). From this parent sample of 20,774 objects we select a subset of 399 with offset broad Balmer emission lines, based on the spectral region around Hβ and [O III]. Our selection was a combination of automated spectral fitting (Shen et al. 2008, J/ApJ/680/169; 2011, J/ApJS/194/45) and visual examination. Here and throughout, we refer to the 399 objects as the "offset" sample. Using the spectral models, we measure the offset of the broad emission lines relative to the systemic velocity. The systemic redshift is estimated from the core component of [O III], which may be different (by a median offset of 32 km/s with a standard deviation of 125 km/s) from the nominal redshift listed by the DR7 catalog based on the SDSS spectroscopic pipeline (Stoughton et al. 2002AJ....123..485S). Our adopted systemic redshift agrees with the improved redshift for SDSS quasars from Hewett & Wild (2010, J/MNRAS/405/2302) within uncertainties. (1 data file).

  12. [Combining herbs with medication--risks vs. chances].

    PubMed

    2013-07-01

    Traditional herbal medicine is driven by the use of plants or parts of plants, which have undergone minimal processing in order to treat disease and improve health. The article: "Traditional Immunosuppression--Lei Gong Teng in Modern Medicine", published in this issue of "Harefuah", raises the importance of integrating herbal medicine within the existing medical system. However, there are various limitations on integrating herbology in official frameworks, such as bureaucratic and legislative restrictions concerning the safety and efficacy of the herbs. This allows the marketing of many plants without a prescription requirement or professional advice. Another limitation relates to therapists, some of whom have not undergone proper training and may recommend the improper use of plants, resulting in a problematic combination with drugs in some cases. Regulation is necessary in order to better serve both the public and doctors. Regulation will define who is allowed to work with herbs and this will create a secure integration of herbs into the formal medical world.

    Significant evidence supports the effectiveness and safety of several complementary or integrative treatment approaches to common primary care problems. Acupuncture is effective in the management of chronic low back pain. Mind-body interventions such as cognitive behavior therapy, yoga, tai chi, qi gong, and music therapy may be helpful for treating insomnia. Exercise can reduce anxiety symptoms. Herbal preparations and nutritional supplements can be useful as first-line therapy for certain conditions, such as fish oil for hypertriglyceridemia, St. John's wort for depression, and Ginkgo biloba extract for dementia, or as adjunctive therapy, such as coenzyme Q10 for heart failure. Probiotic supplementation can significantly reduce the likelihood of antibiotic-associated diarrhea. Physicians should caution patients about interactions, and counsel them about the quality and safety of herbal and nutritional supplements.

    A scheme for generating a fractal butterfly Floquet spectrum, first proposed by Wang and Gong [Phys. Rev. A 77, 031405(R) (2008)], is extended to driven SU(2) systems such as a driven two-mode Bose-Einstein condensate. A class of driven systems without a link with the Harper-model context is shown to have an intriguing butterfly Floquet spectrum. The found butterfly spectrum shows remarkable deviations from the known Hofstadter's butterfly. In addition, the level crossings between Floquet states of the same parity and between Floquet states of different parities are studied and highlighted. The results are relevant to studies of fractal statistics, quantum chaos, and coherent destruction of tunneling, as well as the validity of mean-field descriptions of Bose-Einstein condensates.

  15. Detecting payload performance based on relative radiometric characteristic: case of the optical sensors

    In this paper, we propose a novel algorithm for accurately estimating the degree of radiometric non-uniformity in remote sensing images. The algorithm was tested on high-quality images and heavily striping images, and quantitative analyses were conducted to evaluate the performance for each band by measuring the radiometric non-uniformity of the images. The results demonstrated that the proposed algorithm exhibits high accuracy and stability compared with traditional algorithms. The radiometric performance of TianGong-1 short-wave infrared images was calculated using this new method, and it was highly correlated with the solar angle, pitch angle and refrigerator thermal according to the Apriori algorithm. Based on these results, we have proposed a strategy for restricting increases in striping.

    The 60-foot solar tower at Mount Wilson Observatory took high resolution dopplergrams at a cadence of one minute between the summers of 1988 and 2006. Because this instrument overlaps with GONG and MDI, it provides a unique opportunity to extend the inferences of those two projects backwards in time to solar cycle 22. Furthermore, access to the MWO data has been facilitated by its ingestion at the Joint Science Operations Center (JSOC) at Stanford. For this initial study we choose for our analysis a single summer in which MDI was also operating. By running the MWO data through the same processing pipeline and comparing with the results from MDI, we are able to determine how accurately the two datasets can be combined. In future we will be able to use the MWO data to compare the torsional oscillation during solar cycles 22 and 23.

    Long uninterrupted sequences of solar magnetograms from the global oscillations network group (GONG) network and from the solar and heliospheric observatory (SOHO) satellite will provide the opportunity to study the proper motions of magnetic features. The possible use of multiscale regularization, a scale-recursive estimation technique which begins with a prior model of how state variables and their statistical properties propagate over scale. Short magnetogram sequences are analyzed with the multiscale regularization algorithm as applied to optical flow. This algorithm is found to be efficient, provides results for all the spatial scales spanned by the data and provides error estimates for the solutions. It is found that the algorithm is less sensitive to evolutionary changes than correlation tracking.

    This paper is concerned with the polarization states of an inhomogenously refracted P-wave induced from the interface of two anisotropic rocks. Two realistic physical models have been studied: Model-1 is an interface between anisotropic shale and Taylor sandstone; Model-2 is an interface between anisotropic shale and oil shale. For each model, an analytical expression of the polarization states was derived and its elliptical-polarization trajectory was examined. It is shown that an anomalous incident-angle leads not only to a sudden elliptical-polarization directional variation but also to an abrupt change in size and shape of its elliptical-polarization trajectory. The calculated results and analyses provide a theoretical base for the understandings of an anomalous incident-angle recently reported in the literature [e.g., Fa, Fa, Zhang, Ding, Gong, Li, Li, Tang, and Zhao (2015).

    The Global Oscillation Network Group (GONG) Project is planning to place a set of instruments around the world to observe solar oscillations as continuously as possible for at least three years. The Project has now chosen the sites that will comprise the network. This paper describes the methods of data collection and analysis that were used to make this decision. Solar irradiance data were collected with a one-minute cadence at fifteen sites around the world and analyzed to produce statistics of cloud cover, atmospheric extinction, and transparency power spectra at the individual sites. Nearly 200 reasonable six-site networks were assembled from the individual stations, and a set of statistical measures of the performance of the networks was analyzed using a principal component analysis. An accompanying paper presents the results of the survey.

    The purpose of this quasi-experimental study was to determine the efficacy of Five-Element Gymnastics (FEG) in controlling glycosylated hemoglobin (HbA1C), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), and triglycerides (TG) at the 8th and the 16th weeks of intervention for patients with type 2 diabetes in Taiwan. FEG consolidates several traditional Chinese exercises including Qigong, Xiang Gong, and martial arts with gymnastics. The experimental group (n = 31) practiced FEG at home for 16 weeks. The control group (n = 35) maintained usual activities. FEG was associated with decrease of HbA1C, TG, and LDL-C levels at the 8th week and continuous decrease of HbA1C through the 16th week. FEG could be an exercise choice for patients with type 2 diabetes.

    In the 5th year of the Longqing Period (1571) of the Ming Dynasty, with the abolishment of the Massage and Zhuyou Departments (the latter with a primitive witch doctor, who was dominant in administering incantations, prayers, fortune telling and medicine), the number of departments of the Imperial Academy of Medicine was reduced from thirteen to eleven. In the Jiaqing Period, Taoists occupied some positions in the Imperial Academy of Medicine. Some of them became imperial doctors or even the president, which resulted in Emperor Jiaqing pursuing immortality and neglecting duty on national affairs for more than 20 years. The abolishment of the Massage Department was associated with the official system of reform developed by Emperor Longqing and the prime minister, Gao Gong. Against the background of official reform, they also advanced bold reform in the two departments which Taoists occupied.

    2010-01-01

    We expect considerable improvement of time-distance results from the Helioseismic and Magnetic Imager (HMI) instrument as opposed to the earlier MDI and GONG data. The higher data rate makes possible several improvements, including faster temporal sampling (45 sec), smaller spatial pixels (0.5 arc sec), better wavelength coverage (6 samples across the line all transmitted to the ground), and year-round coverage of the full disk. The higher spatial resolution makes possible better longitude coverage of active regions and supergranulation and also better latitude coverage. Doppler, continuum, and line depth images have a strong granulation signal. Line core images show little granulation. Analyses to test the limits of these new capabilities will be presented.

    Solar flares are explosive phenomena, thought to be driven by magnetic free energy accumulated in the solar corona. Some flares release seismic transients, "sunquakes", into the Sun's interior. Different mechanisms are being considered to explain how sunquakes are generated. We are conducting an analysis of white-light emission associated with those seismically active solar flares that have been reported by different authors within the current solar cycle. Seismic diagnostics are based upon standard time-distance techniques, including seismic holography, applied to Dopplergrams obtained by SDO/HMI and GONG. The relation between white-light emissions and seismic activity may provide important information on impulsive chromospheric heating during flares, a prospective contributor to seismic transient emission, at least in some instances. We develop a method to get an estimation of Energy associated whit white-light emission and compare those results whit values of energy needed to generate a sunquake according with holographic helioseismology techniques.

    Integrative medicine (IM) approaches have gained significant interest in recent years to provide a solution for the health care challenges we face today. Yogic cognitive-behavioral practices are among the most widely used IM approaches and include diverse practices such as yoga asanas, meditation, breathing exercises, Qi Gong, Tai Chi Chih, and various others. Studies to date suggest that these yogic/meditative practices have significant positive effects on the mind-body system and thereby can increase wellness and support the healing process from disease. Previous work has provided evidence for both psychological and physiological effects of these practices; however, the mechanisms of these effects, especially at the molecular level, have largely been missing. Three recent studies started to provide some of this information through gene expression profiling in circulating immune cells, which support the hypothesis that yogic/meditative practices have a measurable effect at the molecular level. These studies are reviewed herein and some future perspectives are considered.

    In terms of an interatomic pair potential, which well characterizes the dynamic properties of liquid Ga, we investigate again the origin of the well known high-q shoulder in the static structure factor of the liquid. Similar to the results of Gong's simulation at high temperature, dimers with extremely short bond lengths are indeed found in our model just above the melting point, but our results indicate that it is unlikely for the high-q shoulder to be produced by these dimers. Instead, based on our model, the high-q shoulder is resulted from some medium-range order, which is related to the structures beyond the first shell of the radial distribution function, caused by Friedel oscillations within a nanoscale range.

    Solar flares are responsible for a number of hazardous effects on the earth such as disabling high-frequency radio communications, interfering with GPS measurements, and disrupting satellites. However, forecasting flare occurrence is currently very difficult. One possible means for predicting flare occurrence lies in helioseismology, i.e. analysis of the region below the active region for signs of an impending flare. Time series helioseismic data collected by the Global Oscillation Network Group (GONG) has been analyzed for a subset of active regions that produce large flares and a subset with very high magnetic field strength that produce no flares. A predictive parameter has been developed and analyzed using discriminant analysis as well as traditional forecasting tools such as the Heidke skill score. Preliminary results show that this parameter predicts the flaring probability of an active region 2-3 days in advance with a relatively high degree of success.

    We analyze the coherent transport of a single photon, which propagates in a one-dimensional coupled-resonator waveguide and is scattered by a controllable two-level system located inside one of the resonators of this waveguide. Our approach, which uses discrete coordinates, unifies low and high energy effective theories for single-photon scattering. We show that the controllable two-level system can behave as a quantum switch for the coherent transport of a single photon. This study may inspire new electro-optical single-photon quantum devices. We also suggest an experimental setup based on superconducting transmission line resonators and qubits. [4pt] L. Zhou, Z.R. Gong, Y.X. Liu, C.P. Sun, F.

    Dye analysis is important to the understanding of fabric color degradation and technical development of ancient printing and dyeing. In the present study, thin layer chromatography and Raman spectroscopy were used for the analysis of blue dyes from 6 silk fabric of Tang dynasty and decorative painting of Jian Fu Gong, Forbidden City. The applicability of these two methods in the cultural heritages was also studied. The results indicate that all these blue substances are indigo; indigo was not only used as dye in ancient fabrics, but also as pigment in decorative painting of historic building, so it is used widely. Both analytic methods have advantages and disadvantages; Raman spectroscopy is nondestructive analysis; thin layer chromatography needs small amount of sample, but could give more information.

    Hydrogels are swollen polymer networks containing more than 90% water. Most hydrogels, however, are mechanically too weak to be used as load bearing devices. Gong et al. have overcome this problem by synthesizing hydrogels with a double network (DN) structure. Modifying the polyelectrolyte network structure by polymerization of high molecular weight uncharged polymer in situ, resulted in orders of magnitude increase in their load bearing ability. Despite 90% water, these tough gels exhibit a fracture stress of 170 kg/cm^2, similar to that of articular cartilage found in the bone-joints of human body. In this work, we determined the structure of DN-gels using small angle neutron scattering. Structural origins for high toughness found in DN-gels were then examined by comparing the structure of DN-gels with that of pure polyelectrolyte network and polyacrylamide solution.

    We have continued in collaboration with Dr. Eff-Darwich (University of La Laguna, Tenerife, Spain) the study of the structure, asphericity and dynamics of the solar interior from p-mode frequencies and frequency splittings. In March 2001, Dr. Eff-Darwich came for 3 weeks visit to CfA. During this visit we completed our work on the inversion of the internal solar rotation rate, and submitted a paper describing this work to the Astrophysical Journal. This paper has been recently revised in response to the referee comments and I expect that it will be accepted for publication very soon. We also have analyzed helioseismic data looking for temporal variations of the solar stratification near the base of the convection zone. We have expanded on the initial work that was presented at the SOHO-10/GONG-2000 meeting (October 2000, Tenerife), and are in the process of writing this up. Substantial progress towards the characterization of high-degree p-modes has been achieved. Indeed, in collaboration Dr. Rabello-Soares (Stanford University), we have gained a clear conceptual understanding of the various elements that affect the leakage matrix of the SOI/MDI instrument. This was presented in an invited talk at the SOHO-10/GONG-2000 meeting (October 2000, Tenerife). Once we will have successfully migrated from a qualitative to a quantitative assessment of these effects, we should be able to generate high-degree p-modes frequencies so crucial in the diagnostic of the layers just below solar surface.

  13. Sensitivity of surface characteristics on the simulation of wind-blown-dust source in North America

    Recently, a wind-blown-dust-emission module has been built based on a state-of-the-art wind erosion theory and evaluated in a regional air-quality model to simulate a North American dust storm episode in April 2001 (see Park, S.H., Gong, S.L., Zhao, T.L., Vet, R.J., Bouchet, V.S., Gong, W., Makar, P.A., Moran, M.D., Stroud, C., Zhang, J. 2007. Simulation of entrainment and transport of dust particles within North America in April 2001 ("Red Dust episode"). J. Geophys. Res. 112, D20209, doi:10.1029/2007JD008443). A satisfactorily detailed assessment of that module, however, was not possible because of a lack of information on some module inputs, especially soil moisture content. In this paper, the wind-blown-dust emission was evaluated for two additional dust storms using improved soil moisture inputs. The surface characteristics of the wind-blown-dust source areas in southwestern North America were also investigated, focusing on their implications for wind-blown-dust emissions. The improved soil moisture inputs enabled the sensitivity of other important surface characteristics, the soil grain size distribution and the land-cover, to dust emission to be investigated with more confidence. Simulations of the two 2003 dust storm episodes suggested that wind-blown-dust emissions from the desert areas in southwestern North America are dominated by emissions from dry playas covered with accumulated alluvial deposits whose particle size is much smaller than usual desert sands. As well, the source areas in the northwestern Texas region were indicated to be not desert but rather agricultural lands that were "activated" as a wind-blown-dust sources after harvest. This finding calls for revisions to the current wind-blown-dust-emission module, in which "desert" is designated to be the only land-cover category that can emit wind-blown dust.

    The memory deficits found in individuals with autism spectrum disorder (ASD) may be caused by the lack of an effective strategy to aid memory. The executive control of memory processing is mediated largely by the timely coupling between frontal and posterior brain regions. The present study aimed to explore the potential effect of a Chinese mind-body exercise, namely Nei Gong, for enhancing learning and memory in children with ASD, and the possible neural basis of the improvement. Sixty-six children with ASD were randomly assigned to groups receiving Nei Gong training (NGT), progressive muscle relaxation (PMR) training, or no training for 1 month. Before and after training, the participants were tested individually on a computerized visual memory task while EEG signals were acquired during the memory encoding phase. Children in the NGT group demonstrated significantly enhanced memory performance and more effective use of a memory strategy, which was not observed in the other two groups. Furthermore, the improved memory after NGT was consistent with findings of elevated EEG theta coherence between frontal and posterior brain regions, a measure of functional coupling. The scalp EEG signals were localized by the standardized low resolution brain electromagnetic tomography method and found to originate from a neural network that promotes effective memory processing, including the prefrontal cortex, the parietal cortex, and the medial and inferior temporal cortex. This alteration in neural processing was not found in children receiving PMR or in those who received no training. The present findings suggest that the mind-body exercise program may have the potential effect on modulating neural functional connectivity underlying memory processing and hence enhance memory functions in individuals with autism.

    The frequencies of the solar acoustic oscillations vary over the activity cycle. The variations in other activity proxies are found to be well correlated with the variations in the acoustic frequencies. However, each proxy has a slightly different time behaviour. Our goal is to characterize the differences between the time behaviour of the frequency shifts and of two other activity proxies, namely the area covered by sunspots and the 10.7-cm flux. We define a new observable that is particularly sensitive to the short-term frequency variations. We then compare the observable when computed from model frequency shifts and from observed frequency shifts obtained with the Global Oscillation Network Group (GONG) for cycle 23. Our analysis shows that on the shortest time-scales, the variations in the frequency shifts seen in the GONG observations are strongly correlated with the variations in the area covered by sunspots. However, a significant loss of correlation is still found. We verify that the times when the frequency shifts and the sunspot area do not vary in a similar way tend to coincide with the times of the maxima of the quasi-biennial variations seen in the solar seismic data. A similar analysis of the relation between the 10.7-cm flux and the frequency shifts reveals that the short-time variations in the frequency shifts follow even more closely those of the 10.7-cm flux than those of the sunspot area. However, a loss of correlation between frequency shifts and 10.7-cm flux variations is still found around the same times.

    The Discriminant Analysis Flare Forecasting System (DAFFS) has been developed under NOAA/Small Business Innovative Research funds to quantitatively improve upon the NOAA/SWPC flare prediction. In the Phase-I of this project, it was demonstrated that DAFFS could indeed improve by the requested 25% most of the standard flare prediction data products from NOAA/SWPC. In the Phase-II of this project, a prototype has been developed and is presently running autonomously at NWRA.DAFFS uses near-real-time data from NOAA/GOES, SDO/HMI, and the NSO/GONG network to issue both region- and full-disk forecasts of solar flares, based on multi-variable non-parametric Discriminant Analysis. Presently, DAFFS provides forecasts which match those provided by NOAA/SWPC in terms of thresholds and validity periods (including 1-, 2-, and 3- day forecasts), although issued twice daily. Of particular note regarding DAFFS capabilities are the redundant system design, automatically-generated validation statistics and the large range of customizable options available. As part of this poster, a description of the data used, algorithm, performance and customizable options will be presented, as well as a demonstration of the DAFFS prototype.DAFFS development at NWRA is supported by NOAA/SBIR contracts WC-133R-13-CN-0079 and WC-133R-14-CN-0103, with additional support from NASA contract NNH12CG10C, plus acknowledgment to the SDO/HMI and NSO/GONG facilities and NOAA/SWPC personnel for data products, support, and feedback. DAFFS is presently ready for Phase-III development.

  18. CURRENT AND KINETIC HELICITY OF LONG-LIVED ACTIVITY COMPLEXES

    2015-01-01

    We study long-lived activity complexes and their current helicity at the solar surface and their kinetic helicity below the surface. The current helicity has been determined from synoptic vector magnetograms from the NSO/SOLIS facility, and the kinetic helicity of subsurface flows has been determined with ring-diagram analysis applied to full-disk Dopplergrams from NSO/GONG and SDO/HMI. Current and kinetic helicity of activity complexes follow the hemispheric helicity rule with mainly positive values (78%; 78%, respectively, with a 95% confidence level of 31%) in the southern hemisphere and negative ones (80%; 93%, respectively, with a 95% confidence level of 22% and 14%, respectively) in the northern hemisphere. The locations with the dominant sign of kinetic helicity derived from Global Oscillation Network Group (GONG) and SDO/HMI data are more organized than those of the secondary sign even if they are not part of an activity complex, while locations with the secondary sign are more fragmented. This is the case for both hemispheres even for the northern one where it is not as obvious visually due to the large amount of magnetic activity present as compared to the southern hemisphere. The current helicity shows a similar behavior. The dominant sign of current helicity is the same as that of kinetic helicity for the majority of the activity complexes (83% with a 95% confidence level of 15%). During the 24 Carrington rotations analyzed here, there is at least one longitude in each hemisphere where activity complexes occur repeatedly throughout the epoch. These ''active'' longitudes are identifiable as locations of strong current and kinetic helicity of the same sign.

    This paper aimed to introduce and examine the biography of Sun Xi-miao which I found in The Biography of The Avatamsaka-Sutra, that Fazang) wrote in 692 A.D. This document was neglected to understand Sun who was the famous medical writer of the collection of prescriptions, the Bei ji qian jin yao fang. His life is rather well documented, because he has his own biographies in Jiu Tang shu and Xin Tang shu which cited from Da Tang sin yu, published in 807. But I found several new informations about Sun in The Biography of The Avatamsaka-Sutra, such as he use to be a military medicine in the troops of Li Yuan who became the first emperor, Kao Tsu of Tang dynasty and treat Sun with great favour. This document let us know that the Bei ji qian jin yao fang was dedicated to Kao Tsu, known as published in 652 A.D. My conclusions are as follows: First, it was written by Fazang in 692 A.D, who was the real establisher of the fraternity of the Avatamsaka in China, for the purpose of encouraging to copy the Avatamsaka-Sutra. According to this biography, Sun made 750 copies to persuade the monks and the peoples, and that's the reason Fazang wrote his biography. Secondly, it was not conveyed to posterity, such as Sun was good looking, tall and use to be the medicine of Kao Tsu and dedicated his medical book to the first emperor. It might be left out for Tai Tsung's sake in the official records, who murdered his brother, the heir apparent to the throne, and became the second emperor by himself. On the contrary, it was written in Da Tang sin yu, Jiu and Xin Tang shu that Sun made a prediction that his collection of prescriptions would help the holyman after 50 years from Xuan Di of Northern Chou Dynasty. Holyman meant Tai Tsung. I shows that Sun's biographies in the Da Tang sin yu, Jiu and Xin Tang Shu were based on the documents that might be fabricated and embellished for Tai Tsung. Thirdly, this biography let us know that Sun wote the Bei ji qian jin yao fang under the

    Introduction: The Xin'anjiang(XAJ) model is a conceptual model developed by the group led by Prof. Ren-Jun Zhao, which takes the pan evaporation as one of its input and then computes the effective evapotranspiration (ET) of the catchment by mass balance. Such scheme can ensure a good performance of discharge simulation but has obvious defects, one of which is that the effective ET is spatially-constant over the computation unit, neglecting the spatial variation of variables that influence the effective ET and therefore the simulation of ET and SM by the XAJ model, comparing with discharge, is less reliable. In this study, The XAJ model was improved to employ both energy and mass balance to compute the ET following the energy-mass balance scheme of FEST-EWB. model.

    Hall effect and resistivity measurements have been made on S-doped and Se-doped Ga xIn 1- xSb ( x = 0.78) at hydrostatic pressure up to 15 kbar. With increasing pressure at T = 300 K, in both kind of samples, the electrons are strongly trapped into a resonant impurity level. Moreover, the occupation of this level leads to time-dependent effects at T < 110 K. The activated thermal electron emission, with a potential barrier of ∼180 meV in S-doped and ∼240 meV in Se-doped samples, gives clear evidence for a large lattice relaxation around the impurity centers similar to that responsible for presistent photoconductivity observed in many semiconductor compounds and alloys.

    We consider the problem of the reconstruction of dielectrics from blind backscattered experimental data. The reconstruction is done from time domain data, as opposed to a more conventional case of frequency domain data. Experimental data were collected using a microwave scattering facility which was built at the University of North Carolina at Charlotte. This system sends electromagnetic pulses into the medium and collects the time-resolved backscattered data on a part of a plane. The spatially distributed dielectric constant \\varepsilon _{r}( \\mathbf {x}) ,\\mathbf {x}\\in {R}^{3} is the unknown coefficient of a wave-like PDE. This coefficient is reconstructed from those data in blind cases. To do this, a globally convergent numerical method is used.

    Despite the fact that different Chinese communities have already undergone industrialization and urbanization, Confucian virtues are still regarded as developmental ideals in Chinese culture. Unfortunately, while Confucian virtues are commonly discussed under Chinese philosophies, they are rarely examined in the context of developmental research. In this paper, several key Confucian virtues are discussed, including loyalty ("zhong"), filial piety ("xiao"), benevolence ("ren"), affection ("ai"), trustworthiness ("xin"), righteousness ("yi"), harmony ("he"), peace ("ping"), propriety ("li"), wisdom ("zhi"), integrity ("lian") and shame ("chi"). These Chinese traditional virtues are also linked to the concepts of character strengths and positive youth development constructs highlighted in Western culture. It is argued that Confucian virtues provide an indigenous conceptual framework to understand character strengths and positive youth development in Chinese culture. Furthermore, when service leadership is considered in Chinese contexts, these virtues should be regarded as important cornerstones.

In addition, through the investigation, the following facts emerged: 1) The date of writing of the transcript can be presumed to be between the Kanbun and Enpo eras in the Edo period. 2) The book, called "Kosha-hon", can be presumed to transcribe the lost version of the text in the group of the twelve volumes of XinKan Huangdi Neijing Lingshu. 3) Shibue left side notes, headed "Kosha-hon Hoki", and he used them for revision, but in fact these notes originated in the Ma Taixuan's Huangdi Neijing Lingshu Zhuzheng Fawei.

    Through phase transition-induced band edge engineering by dual doping with In and Mo, a new greenish BiVO4 (Bi1-XInXV1-XMoXO4) is developed that has a larger band gap energy than the usual yellow scheelite monoclinic BiVO4 as well as a higher (more negative) conduction band than H+/H2 potential [0 VRHE (reversible hydrogen electrode) at pH 7]. Hence, it can extract H2 from pure water by visible light-driven overall water splitting without using any sacrificial reagents. The density functional theory calculation indicates that In3+/Mo6+ dual doping triggers partial phase transformation from pure monoclinic BiVO4 to a mixture of monoclinic BiVO4 and tetragonal BiVO4, which sequentially leads to unit cell volume growth, compressive lattice strain increase, conduction band edge uplift, and band gap widening.

    Theoretical investigations of spin polaron in a quantum well in the spin doping superlattice systems Cd1 - xin Mn1 - xout Te/Cd1 - xout Mnxout Te are presented in this paper. A variational procedure within the effective mass approximation is employed in the presence of magnetic held to calculate the donor ionization energy. Spin polaronic shifts are estimated using a mean held theory. The results show that the donor binding energy (i) Increases with the reduction in well sizes (ii) Decreases with the magnetic held is increased for a given well width (iii) Increases to a maximum value at 90 Å and then decreases as the size of the well increases beyond 90 Å and (iv) Spin polaronic shifts to the donor binding energy not only decrease in a magnetic held but also with the well width. The results are compared with the existing available literature.

    We demonstrate that measurements of the photoelectromagnetic effect using terahertz laser radiation may provide a unique opportunity to discriminate between the topological surface states and other highly conductive surface electron states. We performed a case study of mixed (Bi{}1-xIn x )2Se3 crystals undergoing a topological phase transformation due to the transition from the inverse to the direct electron energy spectrum in the crystal bulk at variation of the composition x. We show that for the topological insulator phase, the photoelectromagnetic effect amplitude is defined by the number of incident radiation quanta, whereas for the trivial insulator phase, it depends on the power in a laser pulse irrespective of its wavelength. We assume that such behavior is attributed to a strong damping of the electron-electron interaction in the topological insulator phase compared to the trivial insulator.

    Herschel-HIFI observations of high-J lines (up to Ju = 10) of 12CO, 13CO and C18O are presented toward three deeply embedded low-mass protostars in NGC 1333. The observations show several energetic components including shocked and quiescent gas. Radiative transfer models are used to quantify the C18O envelope abundance which require a jump in the abundance at an evaporation temperature, Tev ~ 25 K, providing new direct evidence of a CO ice evaporation zone around protostars. The abundance in the outermost part of the envelope, X0, is within the canonical value of 2 × 10-4; however the inner abundance, Xin, is found around a factor of 3-5 lower than X0.

    The temporal and spatial distributions of zooplankton communities in the upper, middle, and lower reaches of the Xin'anjiang Reservoir, Zhejiang, China, were investigated monthly, between 2009 and 2010. Silver carp ( Hypophthalmichthys molitrix) and bighead carp ( Aristichthys nobilis) dominated the pelagic fish community of this large, deep reservoir. Cladocerans were distributed evenly throughout the reservoir. Rotifers were mainly found in the upper reaches, while copepods tended to assemble in the lower reaches. The Pearson correlation analysis and stepwise multiple regression were used to identify the major physicochemical gradients influencing community variations. Zooplankton community distributions were influenced by water temperature, dissolved oxygen, phosphorus, nitrogen, and silicon. Excess nutrients, in particular silicon, stimulated rotifer growth. Based on these findings, it is possible to use rotifer density as a bioindicator of eutrophic status in deep reservoir ecosystems.

    Sequence analysis of pRA2, an endogenous 33-kb plasmid from Pseudomonas alcaligenes NCIB 9867 (strain P25X), revealed the presence of a 6256-bp transposon of the Tn3 family, designated Tn5563. Tn5563, which is flanked by two 39-bp inverted repeats, encodes a transposase, a resolvase, and two open reading frames which share amino acid sequence similarities with the mercuric ion transport proteins MerT and MerP encoded by several mer operons. However, no other mer operon genes were found on Tn5563. Sequencing of a RP4::XIn hybrid plasmid indicates possible interactions between pRA2 and the P25X chromosome mediated by Tn5563.

This continuum represents composite fluctuations that illustrate the breakdown of single magnons originating from the delicate energy balance between localized 4f and itinerant behavior in a heavy metal. The experiment therefore shows how quasiparticle behavior is changed by the close proximity of quantum criticality.

    Equivalent interactions in a low-momentum space for the {lambda}N,{sigma}N, and {xi}N interactions are calculated, using the SU{sub 6} quark model potential as well as the Nijmegen OBEP model as the input bare interaction. Because the two-body scattering data has not been accumulated sufficiently to determine the hyperon-nucleon interactions unambiguously, the construction of the potential even in low-energy regions has to rely on a theoretical model. The equivalent interaction after removing high-momentum components is still model dependent. Because this model dependence reflects the character of the underlying potential model, it is instructive for better understanding of baryon-baryon interactions in the strangeness sector to study the low-momentum space YN interactions.

    We present the first large-scale, quantitative examination of mind and body concepts in a set of historical sources by measuring the predictions of folk mind-body dualism against the surviving textual corpus of pre-Qin (pre-221 BCE) China. Our textual analysis found clear patterns in the historically evolving reference of the word xin (heart/heart-mind): It alone of the organs was regularly contrasted with the physical body, and during the Warring States period it became less associated with emotions and increasingly portrayed as the unique locus of "higher" cognitive abilities. We interpret this as a semantic shift toward a shared cognitive bias in response to a vast and rapid expansion of literacy. Our study helps test the proposed universality of folk dualism, adds a new quantitative approach to the methods used in the humanities, and opens up a new and valuable data source for cognitive scientists: the record of dead minds.

    The traditional Chinese medicine (TCM) theory of "treating heart and brain diseases with same methods (Nao Xin Tong Zhi: NXTZ)" has great significance to the treatment of cardiovascular and cerebrovascular diseases. It has been proven effective by a great deal of clinical researches. However, the underlying mechanism for this theory is still unclear. To provide insights into the potential mechanism of "NXTZ", this study attempts to deeply investigate the mechanism from two representative cardiovascular and cerebrovascular diseases, coronary heart disease (CHD) and cerebral apoplexy. First, various data resources were integrated to obtain different types of biomedical entities including drugs, targets, pathways and diseases. Then, three different approaches including text mining, biological network and enrichment analysis were utilized to recognize the potential common features between CHD and cerebral apoplexy, and the corresponding functions of drugs which could treat both diseases, thus unveiling the mechanism of NXTZ.

    The newly established intermetallic compound LiAg 2In crystallizes in the MnCu 2Al-type structure ( Fm-3 m, Heusler phase) with a=6.5681(5) Å. The homogeneity range of this phase in the ternary Li-Ag-In phase diagram along the adjacent quasibinary cut Li 0.25(Ag 1-xIn x) 0.75 was determined by X-ray powder diffraction and extends from x˜0.33, Li 0.25Ag 0.50In 0.25, up to x˜0.44, Li 0.25Ag 0.42In 0.33. The homogeneity ranges of Heusler- and Zintl-type phases in the Li-Ag-In system are separated from each other by a broad heterogeneous region.

    The name of Wuzhuyu (Medicinal Evodia Fruit) comes from the place of "Wu", and the shape of its fruit, which is like a 'Zhuyu'. In addition, it is also called "Yi, Sha, Jiao, Dang, Yuejiao and Qiu" for different reasons; for example, "Yi" because of its processing and sacrificial function; and "Sha" because of the bug-killing function of its root and cortex. In Xin Xiu Ben Cao (Newly Revised Materia Medica) of the Tang Dynasty, its names were unified as Wuzhuyu. Because it can be eaten, it was also called "Shizhuyu". In the Song Dynasty, with the discontinued vogue of eating Zhuyu, people had difference attitudes to the "Wuzhuyu" and "Shizhuyu". Nowadays, "Wuzhuyu" is the established name of these kinds of materia medica.

  4. Refined comparison theorems for the Dirac equation with spin and pseudo-spin symmetry in d dimensions

    The classic comparison theorem of quantum mechanics states that if two potentials are ordered then the corresponding energy eigenvalues are similarly ordered, that is to say if Va≤ Vb, then Ea≤ Eb. Such theorems have recently been established for relativistic problems even though the discrete spectra are not easily characterized variationally. In this paper we improve on the basic comparison theorem for the Dirac equation with spin and pseudo-spin symmetry in d≥ 1 dimensions. The graphs of two comparison potentials may now cross each other in a prescribed manner implying that the energy values are still ordered. The refined comparison theorems are valid for the ground state in one dimension and for the bottom of an angular momentum subspace in d>1 dimensions. For instance in a simplest case in one dimension, the condition Va≤ Vb is replaced by Ua≤ Ub, where Ui(x)=int0x Vi(t)dt, xin[0,∞), and i=a or b.

    Demodex is a type of permanent obligatory parasite, which can be found on the human body surface. Currently, drugs targeting Demodex usually result in adverse effects and have a poor therapeutic effect. Thus, the aim of the present study was to investigate the use of Chinese crude medicine volatile oils for targeting and inhibiting Demodex in vitro. The volatile oils of six Chinese crude medicines were investigated, including clove, orange fruit, Manchurian wildginger, cinnamon bark, Rhizome Alpiniae Officinarum and pricklyash peel, which were extracted using a distillation method. The exercise status of Demodex folliculorum and Demodex brevis and the antiparasitic effects of the volatile oils against the two species were observed using microscopy. A skin irritation test was used to examine the irritation intensity of the volatile oils. In addition, an acute toxicity test was utilized to observe the toxicity effects of the volatile oils on the skin. Xin Fumanling ointment was employed as a positive control to identify the therapeutic effects of the volatile oils. The results indicated that all six volatile oils were able to kill Demodex efficiently. In particular, the clove volatile oil was effective in inducing optimized anti-Demodex activity. The lethal times of the volatile oils were significantly decreased compared with the Xin Fumanling ointment (P<0.05). Furthermore, the skin irritation test results indicated that the clove volatile oil did not trigger any irritation (0.2 and 0.3 points for intact and scratched skin, respectively), and had a safety equal to that of distilled water. There were not any adverse effects observed following application of the clove volatile oil on the intact or scratched skin. In conclusion, the volatile oils of Chinese crude medicines, particularly that of clove, demonstrated an evident anti-Demodex activity and were able to kill Demodex effectively and safely in vivo.

  7. Trade-off between morphology, extended defects, and compositional fluctuation induced carrier localization in high In-content InGaN films

    We elucidate the role of growth parameters (III/N flux ratio, temperature TG) on the morphological and structural properties, as well as compositional homogeneity and carrier localization effects of high In-content (x(In) > 0.75) In-polar InGaN films grown by plasma-assisted molecular beam epitaxy (PAMBE). Variations in III/N flux ratio evidence that higher excess of In yields higher threading dislocation densities as well as larger compositional inhomogeneity as measured by x-ray diffraction. Most interestingly, by variation of growth temperature TG we find a significant trade-off between improved morphological quality and compositional homogeneity at low-TG (˜450-550 °C) versus improved threading dislocation densities at high-TG (˜600-630 °C), as exemplified for InGaN films with x(In) = 0.9. The enhanced compositional homogeneity mediated by low-TG growth is confirmed by systematic temperature-dependent photoluminescence (PL) spectroscopy data, such as lower PL peakwidths, >5× higher PL efficiency (less temperature-induced quenching) and a distinctly different temperature-dependent S-shape behavior of the PL peak energy. From these, we find that the carrier localization energy is as low as ˜20 meV for low-TG grown films (TG = 550 °C), while it rises to ˜70 meV for high-TG grown films (TG = 630 °C) right below the onset of In-N dissociation. These findings point out that for the kinetically limited metal-rich PAMBE growth of high In-content InGaN a III/N flux ratio of ˜1 and low-to-intermediate TG are required to realize optically more efficient materials.

    Genome-wide association studies (GWASs) have revealed several genetic loci associated with HIV-1 outcome following infection (e.g., HLA-C at 6p21.33) in multi-ethnic populations with genetic heterogeneity and racial/ethnic differences among Caucasians, African-Americans, and Hispanics. To systematically investigate the inherited predisposition to modulate HIV-1 infection in Chinese populations, we performed GWASs in three ethnically diverse HIV-infected patients groups (i.e., HAN, YUN, and XIN, N = 538). The reported loci at 6p21.33 was validated in HAN (e.g., rs9264942, P = 0.0018). An independent association signal (rs2442719, P = 7.85 × 10(-7), HAN group) in the same region was observed. Imputation results suggest that haplotype HLA-B*13:02/C*06:02, which can partially account for the GWAS signal, is associated with lower viral load in Han Chinese. Moreover, several novel loci were identified using GWAS approach including the top association signals at 6q13 (KCNQ5, rs947612, P = 2.15 × 10(-6)), 6p24.1 (PHACTR1, rs202072, P = 3.8 × 10(-6)), and 11q12.3 (SCGB1D4, rs11231017, P = 7.39 × 10(-7)) in HAN, YUN, and XIN groups, respectively. Our findings imply shared or specific mechanisms for host control of HIV-1 in ethnically diverse Chinese populations, which may shed new light on individualized HIV/AIDS therapy in China.

    The RNA genome of Rice tungro spherical virus (RTSV) is predicted to be expressed as a large polyprotein precursor (Shen et al., Virology 193, 621-630, 1993 ). The polyprotein is processed by at least one virus-encoded protease located adjacent to the C-terminal putative RNA polymerase which shows sequence similarity to viral serine-like proteases. The catalytic activity of this protease was explored using in vitro transcription/translation systems. Besides acting in cis, the protease had activity in trans on precursors containing regions of the 3' half of the polyprotein but did not process a substrate consisting of a precursor of the coat proteins. The substitution mutation of Asp(2735) of the RTSV polyprotein had no effect on proteolysis; however, His(2680), Glu(2717), Cys(2811) and His(2830) proved to be essential for catalytic activity and could constitute the catalytic centre and/or substrate-binding pocket of the RTSV 3C-like protease.

    These essays collectively present new perspectives on the history of modem science in China since 1900. Fa-ti Fan describes how science under the Republic of China after 1911 exhibited a complex local and international character that straddled both imperialism and colonialism. Danian Hu focuses on the fate of relativity in the physics community in China after 1917. Zuoyue Wang hopes that a less nationalist political atmosphere in China will stimulate more transnational studies of modern science, which will in turn reveal the underlying commonalities in different national contexts. Sigrid Schmalzer compares the socialist and the capitalist contexts for science in China and reopens the sensitive question of the "mass line" during the Cultural Revolution. Grace Shen describes the tensions early Chinese scientists felt when choosing between foreign models for modem geology and their own professional identities in China. Taken together, these accounts present us with a comparative history of modern science in China that is both globally and locally informed.

    2014-11-01

    There are many studies of the dynamics of swimming microorganisms. There are far fewer studies of how bacteria that attach to surfaces respond to motions of the surrounding fluid. Such motions can influence bacterial orientation, which can, in turn, impact bacterial colonization and motility on surfaces. Moreover, as biofilms develop, stresses from the flow on the surface can cause three-dimensional rearrangements of the soft biofilm in the form of ``streamers'' that can bridge the sides of a porous system; such suspended filaments trigger rapid clogging. Some of the underlying fluid dynamics will be discussed in the spirit of how the flow couples to the spatial and temporal evolution of these bacterial systems. Joint work with N. Autrusson, B. Bassler, K. Drescher, Z. Gitai, L. Guglielmini, F. Ingremeau, M.K. Kim, S. Lecuyer, O. Pak, A. Persat, R. Rusconi, Y. Shen, A. Siryaporn, N. Wingreen.

    The Three Gorges Dam (TGD), the world’s largest source of ‘clean’ hydroelectric power (Shen and Xie 2004), has entered its tenth year after the first turbine went into operation in June 2003. The dam, with a generating capacity 20 times that of the United States’ Hoover Dam, has been hailed as a crucial part of a solution to China’s energy crisis. Despite great benefits, however, major concerns have been voiced over the disastrous environmental and social consequences of this massive engineering project (Stone 2011). In this paper, we review the benefits and impacts learned from the controversial megadam over the past decade and discuss perspective quests on policy overhaul for future environmental protection.

    A search of previous records in the literatures was done to summarize the opinions for dementia in ancient China. The earliest description of dementia was traced in the Yellow emperor's internal classic, a book written 2000 years ago. Hua Tuo (AD 140-208) in Han Dynasty first denominated "dementia" in the book, Hua Tuo Shen Yi Mi Zhuan. The pathogenesis of dementia could be generalized as the insufficiency of Qi, a flowing energy; the stagnation of phlegm, a harmful liquid substance in the body; and the blood stasis, which were also regarded as therapeutic targets. Therefore, we can conclude that dementia has been recognized and investigated in traditional Chinese medicine, which is definitely before the industrial civilization era.

    We study the non-uniform nuclear matter using the self-consistent Thomas-Fermi approximation with a relativistic mean-field model. The non-uniform matter is assumed to be composed of a lattice of heavy nuclei surrounded by dripped nucleons. At each temperature T, proton fraction Y{sub p} , and baryon mass density ρ {sub B}, we determine the thermodynamically favored state by minimizing the free energy with respect to the radius of the Wigner-Seitz cell, while the nucleon distribution in the cell can be determined self-consistently in the Thomas-Fermi approximation. A detailed comparison is made between the present results and previous calculations in the Thomas-Fermi approximation with a parameterized nucleon distribution that has been adopted in the widely used Shen equation of state.

Dislocation climb-bypassing’, typical in intermediate’ volume fraction (~20%) alloys, is considered as the primary deformation mechanism. Dislocation shearing’ to anti-phase boundary (APB) faults and diffusional creep are also considered for high-stress and high-temperature low-stress conditions, respectively. Additional damage mechanism is taken into account for rapid increase in tertiary creep strain. The model has been applied to Alloy 282, and calibrated in a temperature range of 1375-1450°F, and stress range of 15-45ksi. The model parameters and a MATLAB code are provided.

    We developed a new technique for the measurement of terahertz reflection responses utilizing a propagating phonon polariton wave. Frequency tunable phonon polariton waves were generated by the recently developed continuously variable spatial frequency transient grating method [K. Katayama, H. Inoue, H. Sugiya, Q. Shen, T. Taro, and K. A. Nelson, Appl. Phys. Lett. 92, 031906 (2008)]. The phonon polariton wave traveled in a ferroelectric crystal in an in-plane direction with an inclined angle of 26°, and the wave reflected at the crystal edge where a sample was positioned. The reflected polariton wave was detected by the same method as that used for the generation of the polariton waves. By comparing the reflection intensities in the presence and absence of the sample, reflectivity of the polariton wave was calculated, and the refractive index and absorption in the terahertz region were obtained.

Our eight-year longitudinal study, published in the Asian American Journal of Psychology [Kim, Wang, Orozco-Lapray, Shen, & Murtuza, 2013b], demonstrates that tiger parenting is not a common parenting profile in a sample of 444 Chinese American families. Tiger parenting also does not relate to superior academic performance in children. In fact, the best developmental outcomes were found among children of supportive parents. We examine the complexities around defining tiger parenting by reviewing classical literature on parenting styles and scholarship on Asian American parenting, along with Amy Chua's own description of her parenting method, to develop, define, and categorize variability in parenting in a sample of Chinese American families. We also provide evidence that supportive parenting is important for the optimal development of Chinese American adolescents.

However, in acupuncture and moxibustion works before the Song Dynasty, this acupoint was not used to treat eye diseases. In Dou Hanqing's Zhen jiu biao you fu (Song to Elucidate Mysteries in Acupuncture Moxibustion), Guangming was used to treat oculopathy as an alias of Cuanzhu (BL2). Influenced by this, the alias "Guangming" was mistaken as Guangming (GB37) of the Gallbladder Meridian in the Bian que shen ying zhen jiu yu long jing (Bian Que Acupuncture and Moxibustion Jade Dragon Classic) of the Yuan Dynasty, and the symptom of eye itch was added to the indications of Guangming (GB37). This was wrongly informed in the later acupuncture and moxibustion works, and the modern scholars also accepted it and confirmed its effect by the clinical and experimental research.

    Dry seeds of Nicotiana tabacum (L) cv. K346 were flown with a recoverable satellite, the Chinese "Shen Zhou III" for 162 h. After spaceflight, a crinkly leaf and delay flowering mutant of tobacco ( T-cldf), which phenotype differed from the ground control (K346), was obtained from the seedlings after 48 d of the recoverable satellite-flown seeds germination. Major characteristics of T-cldf phenotype included crinkly leaf with outgrowth of the adaxial surface among the secondary veins and delay flowering. Amplified fragment length polymorphism (AFLP) analysis showed that five polymorphic bands were detected between T-cldf and ground control. The results suggested that recoverable satellite-flown condition could bring inheritable mutagenic effects on tobacco seeds and maybe used as a tool for accelerating the progress in tobacco breeding.

    A study was conducted with a line-imaging velocity interferometer on sandwich targets at the Shen Guang-III prototype laser facility in China, with the goal of eliminating the preheat effect. A sandwich target structure was used to reduce the x-ray preheat limitation (radiation temperature ˜170 eV) in a radiative drive shock experiment. With a thick ablator, the preheat effect appeared before the shock arrived at the window. After adding a shield layer of high-Z material on the ablator, x-rays which penetrated the ablator were so weak that the blank-out effect could not be measured. This experiment indicates that the sandwich target may provide a valuable technique in experiments such as equation of state and shock timing for inertial confinement fusion studies.

  3. Bounded Correctors in Almost Periodic Homogenization

    2016-10-01

    We show that certain linear elliptic equations (and systems) in divergence form with almost periodic coefficients have bounded, almost periodic correctors. This is proved under a new condition we introduce which quantifies the almost periodic assumption and includes (but is not restricted to) the class of smooth, quasiperiodic coefficient fields which satisfy a Diophantine-type condition previously considered by Kozlov (Mat Sb (N.S), 107(149):199-217, 1978). The proof is based on a quantitative ergodic theorem for almost periodic functions combined with the new regularity theory recently introduced by Armstrong and Shen (Pure Appl Math, 2016) for equations with almost periodic coefficients. This yields control on spatial averages of the gradient of the corrector, which is converted into estimates on the size of the corrector itself via a multiscale Poincaré-type inequality.

    It is well recognized that harsh outer space environment, consisting of microgravity and radiation, poses significant health risks for human cells. To investigate potential effects of the space environment exposure on cancer cells we examined the biological changes in Caski cells carried by the "Shen Zhou IV" spaceship. After exposure for 7 days in spaceflight, 1440 survival subclonal cell lines were established and 4 cell lines were screened. 44F10 and 17E3 were selected because of their increased cell proliferation and tumorigenesis, while 48A9 and 31F2 had slower cytological events. Experiments with cell proliferation assay, flow cytometry, soft agar assay, tumorigenesis assay and DNA microarray analysis have shown that selected cell lines presented multiple biological changes in cell morphology, cell growth, tumorigenicity and gene expression. These results suggest that space environment exposure can make significant biological impact on cancer cells and provide an entry point to find the immunological target of tumorigenesis.

  5. Simulation of obstacle detection scheme for Mars terrain using minicomputer

    Simulation for detection of obstacles on Martian terrain by a laser rangefinder mounted on an autonomous roving vehicle is achieved by a rapid estimation scheme on a computer with IDIIOM display. Near and far edges of pyramids and hemispherical craters or boulders can be recognized if the obstacles are more than about 15 m from the laser rangefinder and the noise standard deviation is less than about 10 cm. If these conditions are not met the rapid estimation scheme can still detect the top edge of a boulder and the near edge of a crater. The scheme is considered equivalent or better than an earlier (Reed, Sanyal, and Shen, 1974) four-directional Laplacian method, but requires slightly more computation.

    We use the data acquired in the Sloan Digital Sky Survey Reverberation Mapping (SDSS-RM) project, in which a single spectroscopic field was repeatedly observed to explore the variability of quasars. The full technical details of the project are found in Shen et al. (2015, J/ApJS/216/4). SDSS-RM was conducted during the dark/gray time in the final season (2013-2014) of the SDSS-III Baryon Oscillation Spectroscopic Survey (BOSS; Dawson et al. 2013AJ....145...10D). The target field (centered at RAJ2000=14:14:49.00, DEJ2000=+53:05:00.0) coincides with the Panoramic Survey Telescope & Rapid Response System 1 (Pan-STARRS 1; Kaiser et al. 2010SPIE.7733E..0EK) Medium Deep Field MD07, which lies within the Canada-France-Hawaii Telescope Legacy Survey W3 field.

    In his recent study, Gordon Shen analyses a pertinent question facing the global mental health research and practice community today; that of how and why mental health policy is or is not adopted by national governments. This study identifies becoming a World Health Organization (WHO) member nation, and being in regional proximity to countries which have adopted a mental health policy as supportive of mental health policy adoption, but no support for its hypothesis that country recipients of higher levels of aid would have adopted a mental health policy due to conditionalities imposed on aid recipients by donors. Asking further questions of each may help to understand more not only about how and why mental health policies may be adopted, but also about the relevance and quality of implementation of these policies and the role of specific actors in achieving adoption and implementation of high quality mental health policies.

    Numerical simulations for the merger of binary neutron stars are performed in full general relativity incorporating a finite-temperature (Shen's) equation of state (EOS) and neutrino cooling for the first time. It is found that for this stiff EOS, a hypermassive neutron star (HMNS) with a long lifetime (≫10  ms) is the outcome for the total mass ≲3.0M(⊙). It is shown that the typical total neutrino luminosity of the HMNS is ∼3-8×10(53)  erg/s and the effective amplitude of gravitational waves from the HMNS is 4-6×10(-22) at f=2.1-2.5  kHz for a source distance of 100 Mpc. We also present the neutrino luminosity curve when a black hole is formed for the first time.

    Due to the increasing penetration of wind energy into power systems, it becomes critical to reduce the impact of wind energy on the stability and reliability of the overall power system. In precedent works, Shen and his co-workers developed a re-designed operation schema to run wind turbines in strong wind conditions based on optimization method and standard PI feedback control, which can prevent the typical shutdowns of wind turbines when reaching the cut-out wind speed. In this paper, a new control strategy combing the standard PI feedback control with feedforward controls using the optimization results is investigated for the operation of variable-speed pitch-regulated wind turbines in strong wind conditions. It is shown that the developed control strategy is capable of smoothening the power output of wind turbine and avoiding its sudden showdown at high wind speeds without worsening the loads on rotor and blades.

    Objective this randomized single blind clinical study aimed to evaluate the efficacy of auriculotherapy with and without a protocol for reducing stress levels among nursing staff. Method a total of 175 nursing professionals with medium and high scores according to Vasconcelos' Stress Symptoms List were divided into 3 groups: Control (58), Group with protocol (58), Group with no protocol (59). They were assessed at the baseline, after 12 sessions, and at the follow-up (30 days). Results in the analysis of variance, statistically significant differences between the Control and Intervention groups were found in the two evaluations (p<0.05) with greater size of effect indices (Cohen) for the No protocol group. The Yang Liver 1 and 2, Kidney, Brain Stem and Shen Men were the points most used. Conclusion individualized auriculotherapy, with no protocol, could expand the scope of the technique for stress reduction compared with auriculotherapy with a protocol. NCT: 01420835 PMID:25029046

    Two Bi2201 model systems are employed to demonstrate how, beside the Cu-O σ band, a second band of purely O 2pπ character can be made to cross the Fermi level due to its sensitivity to the local crystal field. This result is employed to explain the particle-hole symmetry breaking across the pseudogap recently reported by Shen and co-workers [see M. Hashimoto , Nature Phys.10.1038/nphys1632 6, 414 (2010).]. Support for a two-bands-on-a-checkerboard candidate mechanism for high-Tc superconductivity is claimed. Analysis based on band structures, partial density of states, and sum over states densities scanning-tunneling-microscopy-type images is provided.

    We report the structural and magnetic properties of the nanocrystalline Fe75Si15M10 (M-Al and Cr) powders prepared by mechanical alloying. The milling process produced a non-equilibrium solid solutions of bcc alpha-Fe(Si,Cr) and alpha-Fe(Si,Al). The average dislocation density increases and the average crystallite size decreases with increasing milling time. Magnetic property studies show that the coercivity of the sample increases and magnetization of the sample decreases with increasing milling time. The evolution of a non-equilibrium solid solution and the resulting magnetic properties of nanocrystalline powders are explained on the basis of Neel theory and modified random anisotropy model proposed by Shen et al.

    Current management of the grizzly bear (Ursus arctos) population in Yellowstone National Park and surrounding areas requires annual estimation of the number of adult female bears with cubs-of-the-year. We examined the performance of nine estimators of population size via simulation. Data were simulated using two methods for different combinations of population size, sample size, and coefficient of variation of individual sighting probabilities. We show that the coefficient of variation does not, by itself, adequately describe the effects of capture heterogeneity, because two different distributions of capture probabilities can have the same coefficient of variation. All estimators produced biased estimates of population size with bias decreasing as effort increased. Based on the simulation results we recommend the Chao estimator for model M h be used to estimate the number of female bears with cubs of the year; however, the estimator of Chao and Shen may also be useful depending on the goals of the research.

    Let u ɛ be a solution to the system where , is a smooth uniformly convex domain, and g is 1-periodic in its second variable, and both A ɛ and g are sufficiently smooth. Our results in this paper are twofold. First we prove L p convergence results for solutions of the above system and for the non oscillating operator , with the following convergence rate for all which we prove is (generically) sharp for . Here u 0 is the solution to the averaging problem. Second, combining our method with the recent results due to Kenig, Lin and Shen (Commun Pure Appl Math 67(8):1219-1262, 2014), we prove (for certain class of operators and when ) for both the oscillating operator and boundary data. For this case, we take , where A is 1-periodic as well. Some further applications of the method to the homogenization of the Neumann problem with oscillating boundary data are also considered.

    Shi lin (urolithic stranguria) is a kind of stranguria, manifested as pain occurred when pissing and sand-like in the urine, developed from the early concept of shi long. This name of disease was appeared firstly in Shen nong ben cao jing (Shennong's Classic of Materia Medica), and then, the disease name of sha lin, sha shi lin and sha lin were derived from it by the Song Dynasty. It was said that the disease with sha (sand-like) was easy to treat, and with shi (stone-like) was difficult to cure. This disease was also happened in the children, and the reasons were the same with ones of the adult. Furthermore, there was a name of disease, xue sha lin, which was a kind of woman disease and had nothing to do with shi lin.

    2017-03-01

    In this paper the rate of electron emission from an illuminated hot metallic plate has been evaluated on the basis of the free electron theory of metals and Fowler's theory of photoelectric electron emission. The modification of the electron energy distribution (or enhancement of electron temperature) in the plate by energetic electrons (which get their normal energy enhanced on the surface by incident photons of frequency below threshold and are not emitted) has been taken into account. The thermionic current as modified by the electron temperature so enhanced by irradiation has been evaluated. The results may be applicable to thermionic convertors, as proposed to be operated by Schwede et al. [J.W. Schwede, I. Bargatin, D.C. Riley, B.E. Hardin, S.J. Rosenthal, Y. Sun, F. Schmitt, P. Pianette, R.T. Howe, Z. Shen, N.A. Melosh, Nat. Mater. 9, 762 (2010)]. Numerical results have been presented and discussed.

    In this work, the Balian-Low theorem is extended to Gabor (also called Weyl-Heisenberg) frames for subspaces and, more particularly, its relationship with the unique Gabor dual property for subspace Gabor frames is pointed out. To achieve this goal, the subspace Gabor frames which have a unique Gabor dual of type I (resp. type II) are defined and characterized in terms of the Zak transform for the rational parameter case. This characterization is then used to prove the Balian-Low theorem for subspace Gabor frames. Along the same line, the same characterization is used to prove a duality theorem for the unique Gabor dual property which is an analogue of the Ron and Shen duality theorem.

    Through collecting and collating the development process of traditional Chinese medicine dispensing, the development of modern Chinese medicine dispensing on the basis of experience could be promoted. "Heyaofenji", "Hehe", " Heji" in ancient Chinese medicine, herbal medicine literature and law were collected, and then things were sorted out according to traditional Chinese medicine dispensing theory, skills and legal norms. Firstly, "Tang Ye Jing Fa" is the earliest book which marks the rudiment of traditional Chinese medicine dispensing. Secondly, traditional Chinese medicine dispensing theory formed in "Shen Nong's herbal classic". Thirdly, Zhang Zhongjing's "Treatise on Febrile Diseases" marked the formation of Chinese medicine dispensing skills. Lastly, Provisions in Tang Dynasty law marks the development of traditional Chinese medicine dispensing.
