The Quick Response Team: a pilot project.  

PubMed

The Quick Response Team, consisting of physicians, nurses and social workers in an emergency room setting, conducted a five month pilot project whose overall goal was to eliminate unnecessary admissions to an acute care hospital. This paper reports on the three social work objectives of the program: high risk screening and direct intervention, including assessment, short-term counselling, information, and referral; follow-up services; and social work coverage to all units after hours. Over a 4 month period 11.6% of all patients in the emergency room were assessed by the social work staff and 24 non-acute admissions were deferred. The results of the study confirm the effectiveness of a social work presence in the emergency department in reducing non-acute admissions and in providing continuity of care for patients at high social risk.

Quick response airborne command post communications  

NASA Astrophysics Data System (ADS)

National emergencies and strategic crises come in all forms and sizes ranging from natural disasters at one end of the scale up to and including global nuclear warfare at the other. Since the early 1960s the U.S. Government has spent billions of dollars fielding airborne command posts to ensure continuity of government and the command and control function during times of theater conventional, theater nuclear, and global nuclear warfare. Unfortunately, cost has prevented the extension of the airborne command post technology developed for these relatively unlikely events to the lower level, though much more likely to occur, crises such as natural disasters, terrorist acts, political insurgencies, etc. This thesis proposes the implementation of an economical airborne command post concept to address the wide variety of crises ignored by existing military airborne command posts. The system is known as the Quick Response Airborne Command Post (QRAC Post) and is based on the exclusive use of commercially owned and operated aircraft, and commercially available automated data processing and communications resources. The thesis addresses the QRAC Post concept at a systems level and is primarily intended to demonstrate how current technology can be exploited to economically achieve a national objective.

DNA Barcode Goes Two-Dimensions: DNA QR Code Web Server  

PubMed Central

The DNA barcoding technology uses a standard region of DNA sequence for species identification and discovery. At present, “DNA barcode” actually refers to DNA sequences, which are not amenable to information storage, recognition, and retrieval. Our aim is to identify the best symbology that can represent DNA barcode sequences in practical applications. A comprehensive set of sequences for five DNA barcode markers ITS2, rbcL, matK, psbA-trnH, and CO1 was used as the test data. Fifty-three different types of one-dimensional and ten two-dimensional barcode symbologies were compared based on different criteria, such as coding capacity, compression efficiency, and error detection ability. The quick response (QR) code was found to have the largest coding capacity and relatively high compression ratio. To facilitate the further usage of QR code-based DNA barcodes, a web server was developed and is accessible at http://qrfordna.dnsalias.org. The web server allows users to retrieve the QR code for a species of interests, convert a DNA sequence to and from a QR code, and perform species identification based on local and global sequence similarities. In summary, the first comprehensive evaluation of various barcode symbologies has been carried out. The QR code has been found to be the most appropriate symbology for DNA barcode sequences. A web server has also been constructed to allow biologists to utilize QR codes in practical DNA barcoding applications.

Durability of switchable QR code carriers under hydrolytic and photolytic conditions  

NASA Astrophysics Data System (ADS)

Following a guest diffusion approach, the surface of a shape memory poly(ester urethane) (PEU) was either black or blue colored. Bowtie-shaped quick response (QR) code carriers were then obtained from laser engraving and cutting, before thermo-mechanical functionalization (programming) was applied to stabilize the PEU in a thermo-responsive (switchable) state. The stability of the dye within the polymer surface and long-term functionality of the polymer were investigated against UVA and hydrolytic ageing. Spectrophotometric investigations verified UVA ageing-related color shifts from black to yellow-brownish and blue to petrol-greenish whereas hydrolytically aged samples changed from black to greenish and blue to light blue. In the case of UVA ageing, color changes were accompanied by dye decolorization, whereas hydrolytic ageing led to contrast declines due to dye diffusion. The Michelson contrast could be identified as an effective tool to follow ageing-related contrast changes between surface-dyed and laser-ablated (undyed) polymer regions. As soon as the Michelson contrast fell below a crucial value of 0.1 due to ageing, the QR code was no longer decipherable with a scanning device. Remarkably, the PEU information carrier base material could even then be adequately fixed and recovered. Hence, the surface contrast turned out to be the decisive parameter for QR code carrier applicability.

QR-like algorithms for eigenvalue problems  

NASA Astrophysics Data System (ADS)

In the year 2000 the dominant method for solving matrix eigenvalue problems is still the QR algorithm. This paper discusses the family of GR algorithms, with emphasis on the QR algorithm. Included are historical remarks, an outline of what GR algorithms are and why they work, and descriptions of the latest, highly parallelizable, versions of the QR algorithm. Now that we know how to parallelize it, the QR algorithm seems likely to retain its dominance for many years to come.

A quick-response coolant control system is described for a vehicle engine having a low-flow engine coolant system. A major portion of the coolant flows in a high-flow coolant loop containing an engine block and a minor portion of the coolant fluid flows in a connected low-flow coolant loop, serially containing various components, including a radiator and an aftercooler. It consists of: a high-flow coolant loop including an engine block within the high-flow loop; a low-flow coolant loop connected to the high-flow coolant loop, including a radiator and an aftercooler for cooling engine intake air from a turbocharger; means for sensing the temperature of air leaving the aftercooler; a radiator bypass flow conduit to allow coolant fluid in the low-flow coolant loop to bypass the radiator; a quick-acting, radiator flow control valve in the low-flow loop to mix coolant from the radiator and coolant from the radiator bypass flow conduit; an aftercooler bypass flow conduit to allow coolant fluid in the low-flow coolant loop to bypass the aftercooler; means for sensing the temperature of coolant in the engine block; and a quick-acting, proportional aftercooler shuttle vale in the low-flow coolant loop to proportionally mix coolant from the aftercooler bypass flow conduit and the aftercooler for application to the low-flow coolant loop in response to a signal from the engine block coolant temperature-sensing means to maintain the temperature of the engine block within a desired range.

Pharmacogenomics in the pocket of every patient? A prototype based on quick response codes.  

PubMed

A sizable fraction of patients experiences adverse drug events or lack of drug efficacy. A part of this variability in drug response can be explained by genetic differences between patients. However, pharmacogenomic data as well as computational clinical decision support systems for interpreting such data are still unavailable in most healthcare settings. We address this problem by introducing the medicine safety code (MSC), which captures compressed pharmacogenomic data in a two-dimensional barcode that can be carried in a patient's wallet. We successfully encoded data about 385 genetic polymorphisms in MSC and were able to decode and interpret MSC quickly with common mobile devices. The MSC could make individual pharmacogenomic data and decision support available in a wide variety of healthcare settings without the set up of large-scale infrastructures or centralized databases.

Contourlet based image watermarking using QR decomposition  

NASA Astrophysics Data System (ADS)

The paper presents an image watermarking algorithm based on Contourlet Transform (CT) and QR factorization method. Contourlet Transform is used to transform both the cover and watermark image into subbands. The watermarking is applied to the Contourlet Transform as the human visual system is comparatively less sensitive to edges of the image. The low frequency coefficients of an image contain the highest energy. Thus the lowest frequency coefficients of the contourlet transformed original and watermark image are selected for watermarking. The selected coefficients are then decomposed using QR factorization method. The QR factorized coefficients of watermark image is embedded into the QR factorized original image values. Inverse QR and inverse CT is then applied on the watermark embedded coefficients of image to obtain the watermarked image. Experimental results show that the proposed algorithm is a better technique as compared to other watermarking schemes based on Contourlet Transform. The proposed watermarking scheme is imperceptible and robust against image processing attacks such as Gaussian noise, scaling, compression, salt and pepper noise.

A Quick Response Forecasting Model of Pathogen Transport and Inactivation in Near-shore Regions  

NASA Astrophysics Data System (ADS)

Modeling methods supporting water quality assessments play a critical role by facilitating people to understand and promptly predict the potential threat of waterborne bacterial pathogens pose to human health. A mathematical model to describe and predict bacterial levels can provide foundation for water managers in making decisions on whether a water system is safe to open to the public. The inactivation (decay or die-off) rate of bacteria is critical in a bacterial model by controlling bacterial concentration in waters and depends on numerous factors of hydrodynamics, meteorology, geology, chemistry and biology. Transport and fate of waterborne pathogens in fresh water systems is an essentially three-dimensional problem, which requires a coupling of hydrodynamic equations and transport equations that describe the pathogen and suspended sediment dynamics. However, such an approach could be very demanding and time consuming from a practical point of view due to excess computational efforts. Long computation time may lead people unintentionally drinking or swimming in the contaminated water during the period before the predictive results of water quality come out. Therefore, it is very necessary to find a quick-response model to forecast bacterial concentration instantly to protect human health without any delay. Nearshore regions are the most commonly and directly used area for people in a huge water system. The prior multi-dimensional investigations of E. Coli and Enterococci inactivation in literature indicate that along-shore current predominated the nearshore region. Consequently, the complex dynamic conditions may be potentially simplified to one-dimensional scenario. In this research, a one-dimensional model system coupling both hydrodynamic and bacterial transport modules is constructed considering different complex processes to simulate the transport and fate of pathogens in nearshore regions. The quick-response model mainly focuses on promptly forecasting purpose and will be verified and calibrated with the available data collected from southern Lake Michigan. The modeling results will be compared with those from prior multi-dimensional models. This model is specifically effective for the outfall-controlled waters, where pathogens are primarily predominated by loadings from nearby tributaries and tend to show wide variations in concentrations.

Geo-registration and mosaic of UAV video for quick-response to forest fire disaster  

NASA Astrophysics Data System (ADS)

UAV Video is rapidly emerging as a widely used source of imagery for many applications in recent years. This paper presents our research on the UAV video processing system for the purpose of fire surveillance, which include: (1) UAV video stream processing. This step involves three aspects: decoding, re-sampling and matching. Microsoft(R) DirectX(R) technology is used to decode highly compressed video stream and re-sampled them into still video frame based on the time base and rate of UAV navigation sensor. One feature-based image-matching algorithm is developed to quickly obtain Tie points for latter calibration operation. (2) UAV system orientation. This step also involves three aspects: Camera IOP, Boresight Alignment and bundle adjustment. TSAI's two-stage technique is used to obtain initial camera focus length f, distortion coefficients k1 and six Exterior Of Parameter (EOP) for one selected video image. Meanwhile, the Boresight Matrix is deduced by the comparison of GPS/INS derived parameters with solved EOPs. Further more, all parameters including EOPs of all re-sampled video images and camera IOP are optimally estimated based on developed bundle adjustment algorithm. (3) UAV Video geo-registration and mosaic. All re-sampled video frames are geo-registered into uniform geo-reference coordinate frame vice Classic photogrammetric orthorectification model and merge with each other with developed mosaic algorithm. The results demonstrated that the geo-accuracy of mosaic image generated from UAV video can achieve 1-2 pixels in planimetry and its combination with GIS-supported data for fast response to time-critical event, e.g., forest fire, is descried.

A note on fast computation of effective independence through QR downdating for sensor placement  

NASA Astrophysics Data System (ADS)

A simple and fast computational algorithm of the Effective Independence for sensor placement is presented in the paper. It is based on the relationship between the Effective Independence and Modal Kinetic Energy method, and on a downdating algorithm of the QR decomposition for a reduced modal matrix. Traditional computations of the Effective Independence, which tries to render the target modes as linearly independent at possible and is significant and influential in the field of sensor placement, require the eigenvalue decomposition or inversion of the Fisher Information matrix, and both are costly. By virtue of the connection between the Modal Kinetic Energy and Effective Independence derived by the authors, the norms of the orthonormal rows after the QR decomposition of the modal matrix can be employed to compute the Effective Independence. Moreover, new downdating steps of the QR decomposition based on the combination of the modified Gram-Schmidt and Householder transformations are implemented, which further improved its efficiency by eliminating unnecessary expensive QR decompositions in the iterations. The computational burden for traditional methods and the proposed ones are investigated in terms of the floating point operations required. Finally, a numerical example shows that the new algorithms run much more quickly with fewer computation steps, has the advantages of simplicity and clarity in physical significance, and is stable.

Integrated System for Earthquake Early Warning and Quick Response Against Strong Motion - In Case of the Tokyo Metro Company  

NASA Astrophysics Data System (ADS)

In July 2005, an earthquake of M6.0 attacked the Tokyo metropolitan area. This earthquake occurred at 35.5N and 140.2E with about 73km in depth, and the maximum JMA intensity was 5+ corresponding to MMI VIII approximately. This earthquake occurred at north-west of Chiba prefecture and caused a traffic disturbance widely in Tokyo metropolitan area. All the train operation had been stopped for a long time after the earthquake, although a severe damage was not caused even in the area of high intensity. The longest down time for the train operation was more than seven hours. After the earthquake, we proposed a new system for early warning and quick response. Tokyo Metro Company accepted our proposal, and we replaced and built the new early warning/quick response system as followed. The system consists of two seismometer networks. One is the early warning system FREQL network with six seismometers to control or stop the train operation immediately after the earthquake occurrence. And the other is the portable digital seismometer AcCo network distributing 33 seismometers in every about three kilometers mesh to grasp more detailed seismic motion on their service area. The information from both FREQL network and AcCo network are gathered to the operation center and displayed on the individual monitoring system. The monitoring system for AcCo can indicate the integrated information from AcCo and FREQL on the subway network image. The AcCo monitoring system is also installed on the control table for each subway line. At the time of the earthquake, the early warning system detects at first the earthquake immediately and then the 33 local seismometers inform the actual earthquake motion of each site independently and rapidly. This system realized quick response and restart of the train operation because the early warning became faster and checking zone after earthquake was optimized. This updated system is expected to realize quicker response during and after. For the large system as the train operation, it is necessary for the control against the earthquake to equip the system not only to issue the early warning but also to support the quick and rational recovery work after the earthquake.

Gravity Field Parameter Estimation Using QR Factorization  

NASA Astrophysics Data System (ADS)

This study compares the accuracy of the estimated geopotential coefficients when QR factorization is used instead of the classical method applied at our institute, namely the generation of normal equations that are solved by means of Cholesky decomposition. The objective is to evaluate the gain in numerical precision, which is obtained at considerable extra cost in terms of computer resources. Therefore, a significant increase in precision must be realized in order to justify the additional cost. Numerical simulations were done in order to examine the performance of both solution methods. Reference gravity gradients were simulated, using the EIGEN-GL04C gravity field model to degree and order 300, every 3 seconds along a near-circular, polar orbit at 250 km altitude. The simulation spanned a total of 60 days. A polar orbit was selected in this simulation in order to avoid the 'polar gap' problem, which causes inaccurate estimation of the low-order spherical harmonic coefficients. Regularization is required in that case (e.g., the GOCE mission), which is not the subject of the present study. The simulated gravity gradients, to which white noise was added, were then processed with the GINS software package, applying EIGEN-CG03 as the background gravity field model, followed either by the usual normal equation computation or using the QR approach for incremental linear least squares. The accuracy assessment of the gravity field recovery consists in computing the median error degree-variance spectra, accumulated geoid errors, geoid errors due to individual coefficients, and geoid errors calculated on a global grid. The performance, in terms of memory usage, required disk space, and CPU time, of the QR versus the normal equation approach is also evaluated.

Implicit QR algorithms for palindromic and even eigenvalue problems  

NASA Astrophysics Data System (ADS)

In the spirit of the Hamiltonian QR algorithm and other bidirectional chasing algorithms, a structure-preserving variant of the implicit QR algorithm for palindromic eigenvalue problems is proposed. This new palindromic QR algorithm is strongly backward stable and requires less operations than the standard QZ algorithm, but is restricted to matrix classes where a preliminary reduction to structured Hessenberg form can be performed. By an extension of the implicit Q theorem, the palindromic QR algorithm is shown to be equivalent to a previously developed explicit version. Also, the classical convergence theory for the QR algorithm can be extended to prove local quadratic convergence. We briefly demonstrate how even eigenvalue problems can be addressed by similar techniques.

Microsoft Academic Search

We present a novel data structure called T-Cube which dramatically improves response time to ad-hoc time series queries against large datasets. We have tested T-Cube on both synthetic and real world data (emergency room pa- tient visits, pharmacy sales) containing millions of records. The results indicate that T-Cube responds to complex queries 1,000 times faster when compared to the state-of-the-art

Structures preserved by the QR-algorithm  

NASA Astrophysics Data System (ADS)

In this paper we investigate some classes of structures that are preserved by applying a (shifted) QR-step on a matrix A. We will handle two classes of such structures: the first we call polynomial structures, for example a matrix being Hermitian or Hermitian up to a rank one correction, and the second we call rank structures, which are encountered for example in all kinds of what we could call Hessenberg-like and lower semiseparable-like matrices. An advantage of our approach is that we define a structure by decomposing it as a collection of `building stones' which we call structure blocks. This allows us to state the results in their natural, most general context.

T cells play an important role in the control of hepatitis C virus (HCV) infection. We have previously demonstrated that the HCV core inhibits T-cell responses through interaction with gC1qR. We show here that core proteins from chronic and resolved HCV patients differ in sequence, gC1qR-binding ability, and T-cell inhibition. Specifically, chronic core isolates bind to gC1qR more efficiently and

Identification of a gC1q-binding protein (gC1q-R) on the surface of human neutrophils. Subcellular localization and binding properties in comparison with the cC1q-R.  

PubMed Central

Human neutrophils have multiple C1q-binding proteins. Direct ligand-binding studies with the globular domain of C1q and two-dimensional Western blot analysis revealed two gC1q-binding proteins (gC1q-R): a 33,000 M(r) protein (pI 4.5) mainly in the neutrophil plasma membrane and an 80,000-90,000 M(r) protein (pI 4.1-4.2) located mainly in the granules. Direct binding studies showed that C1q bound to this higher molecular weight protein under physiological conditions. In contrast, anti-cC1q-R antibody, which recognizes a protein binding to collagenous tails of C1q, detected only a 68,000 M(r) protein in the plasma membrane. Both the 33,000 and 68,000 M(r) receptors appear early on the surface of differentiating HL-60 cells. On mature neutrophils, surface expression of both C1q receptors was evident, but no upregulation was observed upon stimulation. Phorbol myristate acetate treatment of neutrophils downregulated both the receptors from cell surface, and significant amounts of soluble gC1q-R were in cell media supernatants, suggesting receptor shedding or secretion. gC1q-R, unlike cC1q-R, did not bind to other C1q-like ligands, namely mannose binding protein, surfactant protein-A, surfactant protein-D, or conglutinin under normal ionic conditions, suggesting a greater specificity for C1q than the "collectin" type receptor (cC1q-R). Rather, gC1q-R only bound purified C1q, and the binding was enhanced under low ionic conditions and in the absence of calcium. The role of C1q receptor shedding and its biologic consequence remain to be defined, but may contribute to the diversity of C1q-mediated responses observed in many cell types. Images

A unitary Hessenberg QR-based algorithm via semiseparable matrices  

NASA Astrophysics Data System (ADS)

In this paper, we present a novel method for solving the unitary Hessenberg eigenvalue problem. In the first phase, an algorithm is designed to transform the unitary matrix into a diagonal-plus-semiseparable form. Then we rely on our earlier adaptation of the QR algorithm to solve the dpss eigenvalue problem in a fast and robust way. Exploiting the structure of the problem enables us to yield a quadratic time using a linear memory space. Nonetheless the algorithm remains robust and converges as fast as the customary QR algorithm. Numerical experiments confirm the effectiveness and the robustness of our approach.

Nested image steganography scheme using QR-barcode technique  

NASA Astrophysics Data System (ADS)

In this paper, QR bar code and image processing techniques are used to construct a nested steganography scheme. There are two types of secret data (lossless and lossy) embedded into a cover image. The lossless data is text that is first encoded by the QR barcode; its data does not have any distortion when comparing with the extracted data and original data. The lossy data is a kind of image; the face image is suitable for our case. Because the extracted text is lossless, the error correction rate of QR encoding must be carefully designed. We found a 25% error correction rate is suitable for our goal. In image embedding, because it can sustain minor perceptible distortion, we thus adopted the lower nibble byte discard of the face image to reduce the secret data. When the image is extracted, we use a median filter to filter out the noise and obtain a smoother image quality. After simulation, it is evident that our scheme is robust to JPEG attacks. Compared to other steganography schemes, our proposed method has three advantages: (i) the nested scheme is an enhanced security system never previously developed; (ii) our scheme can conceal lossless and lossy secret data into a cover image simultaneously; and (iii) the QR barcode used as secret data can widely extend this method's application fields.

The symbology of the QR Code and the traditional techniques for recognizing the finder pattern of the QR Code were introduced and the disadvantages of these techniques were analyzed. Based on the symmetry of the finder pattern of the QR Code, an algorithm for locating the center of the finder pattern was proposed. By this algorithm, the center of the finder pattern of the QR Code can be located accurately even though one module of the QR Code image occupies only 2.8 pixels or the image is skewed seriously or the image is illuminated not uniformly.

2001 QR322: a dynamically unstable Neptune Trojan?  

NASA Astrophysics Data System (ADS)

Since early work on the stability of the first Neptunian Trojan, 2001 QR322, suggested that it was a dynamically stable, primordial body, it has been assumed that this applies to both that object and its more recently discovered brethren. However, it seems that things are no longer so clear-cut. In this work, we present the results of detailed dynamical simulations of the orbital behaviour of 2001 QR322. Using an ephemeris for the object that has significantly improved since earlier works, we follow the evolution of 19683 test particles, placed on orbits within the observational error ellipse of 2001 QR322's orbit, for a period of 1Gyr. We find that majority of these `clones' of 2001 QR322 are dynamically unstable, exhibiting a near-exponential decay from both the Neptunian Trojan cloud (decay half-life of ~550Myr) and the Solar system (decay half-life of ~590Myr). The stability of the object within Neptune's Trojan cloud is found to be strongly dependent on the initial semimajor axis used, with these objects located at a >= 30.30au being significantly less stable than those interior to this value, as a result of their having initial libration amplitudes very close to a critical threshold dividing regular and irregular motion, located at ~70°-75° (full extent of angular motion). This result suggests that if 2001 QR322 is a primordial Neptunian Trojan, it must be a representative of a population that was once significantly larger than that we see today and adds weight to the idea that the Neptune Trojans may represent a significant source of objects moving on unstable orbits between the giant planets (the Centaurs).

Adaptive lattice filters for block RLS based on QR decomposition

Recently, the QR decomposition (QRD) method has been extensively used in the recursive least squares (RLS) adaptive filtering problems. And the least squares lattice (LSL) algorithm has been rederived based on the QRD method. On the other hand, in order to increase the throughput in the general RLS, a triangular systolic array for block processing based on the QRD method with Householder transformations has been derived. In this paper, we derive an adaptive FIR lattice filter structure for block processing based on QRD with Householder transformations.

Lack of association between Alzheimer's disease and Gln-Arg 192 Q/R polymorphism of the PON-1 gene in an Italian population.  

PubMed

Alzheimer's disease (AD) is characterized by deposition of oxidized low-density lipoprotein (LDL) forming the senile plaque and by structural changes and cell death in acetylcholine-producing neurons. Paraoxonase-1 (PON-1) is a secreted protein primarily associated with high-density lipoproteins (HDL) and participates in the prevention of LDL oxidation. PON-1 is also an arylesterase that hydrolyzes paraoxon, an active toxic metabolite of parathion, thus providing protection against organophosphate poisoning and metabolization of environmental neurotoxins that might be responsible for neurodegeneration with aging. Serum levels of PON-1 are genetically determined and strongly influenced by a common polymorphism on the position 192 of the PON-1 gene. The aim of this study was to evaluate whether the polymorphism of the PON-1 gene is associated with AD. We studied 124 Italian subjects affected by probable AD and 135 age- and sex-matched controls. The distribution of PON-1 genotypes was 64 QQ, 46 QR, 14 RR in the AD patients and 57 QQ, 59 QR, 19 RR in the control subjects. No statistically significant difference was found between the two groups in our population (p = 0.130 for homozygous QQ, p = 0.279 for heterozygous QR, and p = 0.502 for homozygous RR). These results suggest that the human Gln-Arg 192 Q/R polymorphism of the PON-1 gene is not associated with AD in an Italian population. PMID:12566597

A multiple shift QR-step for structured rank matrices  

NASA Astrophysics Data System (ADS)

Eigenvalue computations for structured rank matrices are the subject of many investigations nowadays. There exist methods for transforming matrices into structured rank form, QR-algorithms for semiseparable and semiseparable plus diagonal form, methods for reducing structured rank matrices efficiently to Hessenberg form and so forth. Eigenvalue computations for the symmetric case, involving semiseparable and semiseparable plus diagonal matrices have been thoroughly explored. A first attempt for computing the eigenvalues of nonsymmetric matrices via intermediate Hessenberg-like matrices (i.e. a matrix having all subblocks in the lower triangular part of rank at most one) was restricted to the single shift strategy. Unfortunately this leads in general to the use of complex shifts switching thereby from real to complex operations. This paper will explain a general multishift implementation for Hessenberg-like matrices (semiseparable matrices are a special case and hence also admit this approach). Besides a general multishift QR-step, this will also admit restriction to real computations when computing the eigenvalues of arbitrary real matrices. Details on the implementation are provided as well as numerical experiments proving the viability of the presented approach.

Ellagic acid induces NAD(P)H:quinone reductase through activation of the antioxidant responsive element of the rat NAD(P)H:quinone reductase gene.  

PubMed

Induction of cellular detoxification enzymes can increase detoxification of carcinogens and reduce carcinogen-induced mutagenesis and tumorigenesis. To determine if the dietary anticarcinogen ellagic acid induced enzymes which detoxify xenobiotics and carcinogens, we examined the effect of ellagic acid on the expression of the phase II detoxification enzyme NAD(P)H:quinone reductase (QR). QR is induced by xenobiotics and antioxidants interacting with the xenobiotic responsive and antioxidant responsive elements of the 5' regulatory region of the QR gene. Ellagic acid is structurally related to the antioxidants which induce QR and we proposed that ellagic acid would induce QR expression through activation of the antioxidant responsive element of the QR gene. Rats fed ellagic acid demonstrated a 9-fold increase in hepatic and a 2-fold increase in pulmonary QR activity, associated with an 8-fold increase in hepatic QR mRNA. To determine if this increase in QR mRNA was due to activation of the antioxidant responsive element, transient transfection studies were performed with plasmid constructs containing various portions of the 5' regulatory region of the rat QR gene. These transfection studies confirmed that ellagic acid induces transcription of the QR gene and demonstrated that this induction is mediated through the antioxidant responsive element of the QR gene.

Evidence that a C1q/C1qR system regulates monocyte-derived dendritic cell differentiation at the interface of innate and acquired immunity  

PubMed Central

Growing evidence shows that C1q modulates the growth and function of cells committed to the monocyte-derived dendritic cell (DC) lineage. Because C1q regulates both innate and acquired immune responses, we postulated that C1q modulates the transition from monocytes to DCs, i.e. the interface between innate and acquired immunity. Human peripheral blood monocytes cultured with soluble C1q and DC growth factors (GM-CSF + IL-4) failed to down-regulate monocyte-associated (CD14, CD16) and up-regulate DC-associated (CD83, CD86) markers. Impaired DC differentiation was not due to apoptosis; further analysis revealed the development of CD14hiCD11chiCD16+/? cells that have previously been associated with both innate and acquired immunity. Monocyte–DC precursors expressed gC1qR, the receptor for globular heads of C1q, from the outset, while cC1qR, the receptor for the collagen tails of C1q, was expressed at low levels. Notably, the binding pattern of monoclonal antibodies specific to the globular heads of C1q indicated that C1q is bound to monocytes via globular heads, presumably through gC1qR. Moreover, gC1qR levels decreased, while cC1qR levels were dramatically amplified as monocytes differentiated into immature DC. Thus, specific C1q/C1q receptor (R) interactions may control the transition from the monocyte state (innate immunity) toward the professional antigen-presenting cell state (adaptive immunity).

A fully pipelined systolic array structured decision feedback equalizer based on extended QR-RLS algorithm  

NASA Astrophysics Data System (ADS)

This paper introduces a systolic array structured adaptive decision feedback equalizer (DFE) based on extended QR-RLS (QR-decomposition-based Recursive Least Squares) algorithm. In the wireless mobile communication systems, the fast time-varying channel could be experienced, so that high-speed convergence along with precise tracking ability is a crucial requirement for the equalizers. To cope with this, the QR-RLS algorithm has been considered as an adaptation apparatus satisfying these requisitions with showing numerical stability in fixed-point operation. In the aspect of realization, the QR-RLS algorithm could be realized in a form of systolic array, which gives an opportunity of utilizing the parallel pipelined processing. Even the computational complexity can be reduced by avoiding the square-root operations. However, the conventional QR-RLS approach demands the extra weight extraction process, so that the equalization can be hardly accomplished by a full pipelined process. Against this difficulty, this paper exploits the extended QR-RLS algorithm to build up the systolic array structured DFE in efficient. In addition to affirmative features such as the fast convergence and the superb tracking ability, the proposed DFE architecture based on the extended QR-RLS yields a capability of full pipeline process from the input acquisition till the weight update without involving undesirable square-root operations.

QR-LRL Signal Detection for Spatially Multiplexed MIMO Systems  

NASA Astrophysics Data System (ADS)

The performance of the ordered successive interference cancellation (OSIC) signal detection method is well known to depend on the successful detection of the first layer. In a previous work, in an effort to mitigate the error propagation effect, all the constellation points were tried as the first layer symbol, thereby achieving a better performance. In this letter, we show that the selection of the first layer impacts the error performance significantly, and based on the observation, we propose a novel signal detection method QR-LRL. In the proposed work, the least reliable layer (LRL) is chosen to be the first layer, which is shown to be the best choice in terms of noise enhancement in detecting the other layers. Also, we discuss Log Likelihood Ratio (LLR) computation when the proposed method is used. Computer simulations confirm the efficacy of the proposed method.

The restarted QR-algorithm for eigenvalue computation of structured matrices  

NASA Astrophysics Data System (ADS)

The QR-algorithm is a popular numerical method for the computation of eigenvalues of matrices. All eigenvalues of a general n×n upper Hessenberg matrix typically can be computed in arithmetic floating point operations using storage locations. When the upper Hessenberg matrix is Hermitian or unitary, then it can be represented by parameters, and there are variants of the QR-algorithm that reduce the operation count for computing all eigenvalues to arithmetic floating point operations and the storage requirement to locations. However, for many structured matrices that can be represented with storage locations, available implementations of the QR-algorithm require arithmetic floating point operations and storage locations to determine all eigenvalues. This note shows that for some of the latter matrices, the operation count can be reduced to arithmetic floating point operations and the memory requirement to storage locations by periodically restarting the QR-algorithm.

On the ICI Mitigation in OFDM Systems by Using the Segment-Based QR Decomposition  

NASA Astrophysics Data System (ADS)

In this study, a precoding scheme based on QR-decomposition is proposed for mitigating the inter-carrier-interference (ICI) in orthogonal-frequency-division-multiplexing (OFDM) systems. The proposed approach first subjects the ICI matrix to QR decomposition so that the ICI effect is transformed into its spectrally causal equivalent. With this causality, the precoding can then be conducted based on the resultant spectrally causal matrix. In addition, by using the stationary property of the ICI factors, in conjunction with zero padding, we implement the QR-based precoding in a segmentation manner which can significantly alleviate the computational complexity imposed by QR decomposition while eliminating ICI within each segment. This study also analyzes the residue interference power induced by the segmentation. The residue interference power is then accordingly used to determine the order of zero padding. Computer simulations support the validity of the proposed approach.

Optical encryption and QR codes: secure and noise-free information retrieval.

We introduce for the first time the concept of an information "container" before a standard optical encrypting procedure. The "container" selected is a QR code which offers the main advantage of being tolerant to pollutant speckle noise. Besides, the QR code can be read by smartphones, a massively used device. Additionally, QR code includes another secure step to the encrypting benefits the optical methods provide. The QR is generated by means of worldwide free available software. The concept development probes that speckle noise polluting the outcomes of normal optical encrypting procedures can be avoided, then making more attractive the adoption of these techniques. Actual smartphone collected results are shown to validate our proposal. PMID:23482108

The relationship of PON1 QR 192 and LM 55 polymorphisms with serum paraoxonase activities of Turkish diabetic patients.  

PubMed

Paraoxonase (PON1) is a serum esterase responsible for the protection against xenobiotics toxicity such as paraoxon. Alterations in PON1 concentrations have been reported in a variety of diseases including diabetes mellitus (DM). It has been shown that the serum PON1 concentration and activity are decreased in patients with both type 1 and type 2 DM. This study aimed to investigate the lipid profiles and the relationship between PON1 activity and PON1, QR192 and LM55 polymorphisms in Turkish type 2 diabetic patients and non-diabetic control subjects. According to our results, RR variant had significantly higher PON activity than QQ and QR variants (p < 0.01) and LL variant had significantly higher PON activity than MM variant in both control and patient groups (p < 0.05). In conclusion, we found that PON1 192RR and 55LL genotypes are associated with higher PON activity than QQ and MM genotypes. This may be more protective to lipid peroxidation. PMID:21505009

Quick stop device  

DOEpatents

A quick stop device for abruptly interrupting the cutting of a workpiece by a cutter is disclosed. The quick stop device employs an outer housing connected to an inner workpiece holder by at least one shear pin. The outer housing includes an appropriate shank designed to be received in the spindle of a machine, such as a machine tool. A cutter, such as a drill bit, is mounted in a stationary position and the workpiece, mounted to the workpiece holder, is rotated during engagement with the cutter. A trigger system includes at least one spring loaded punch disposed for movement into engagement with the workpiece holder to abruptly stop rotation of the workpiece holder. This action shears the shear pin and permits continued rotation of the spindle and outer housing without substantially disturbing the chip root formed during cutting.

JHAV' - Quick Sort  

NSDL National Science Digital Library

Visualization for Quick Sort. Includes dynamically highlighted pseudo code. Users can select random data, or give their own data. As the presentation progresses, the sub-array processing is shown as branches of a virtual tree. The AV is set up as a series of 'slides' in one pane, and pseudocode in the adjacent pane. As the user steps through the 'slides', the associated pseudocode is highlighted. Occasional questions pop up for the user to answer. This is an exceptionally clear presentation of Quick Sort. The presentation mechanism for showing the subarray processing is effective. The AV is supported by an HTML page that shows complete pseudocode and gives some guidance on using the AV, though the guide questions are not so extensive as for some other JHAV' topics. There are probably too many 'states' being displayed, since each line of pseudocode gets its own slide. This can be a bit tedious. Some pruning of some of the states might help, but this is probably difficult since the slide show gets generated from the data input. Recommended as lecture aide, standalone, self-study suppliment to tutorial or lecture.

Efficient algorithms for computing a strong rank-revealing QR factorization  

SciTech Connect

Given an m x n matrix M with m {ge} n, it is shown that there exists a permutation {Pi} and an integer k such that the QR factorization given by equation (1) reveals the numerical rank of M: the k x k upper-triangular matrix A{sub k} is well conditioned, norm of (C{sub k}){sub 2} is small, and B{sub k} is linearly dependent on A{sub k} with coefficients bounded by a low-degree polynomial in n. Existing rank-revealing QR (RRQR) algorithms are related to such factorizations and two algorithms are presented for computing them. The new algorithms are nearly as efficient as QR with column pivoting for most problems and take O(mn{sup 2}) floating-point operations in the worst case.

Nonlinear Phenomena and Resonant Parametric Perturbation Control in QR-ZCS Buck DC-DC Converters  

NASA Astrophysics Data System (ADS)

The purpose of this study is to investigate the chaotic phenomena and to control in current-mode controlled quasi-resonant zero-current-switching (QR-ZCS) DC-DC buck converters, and to present control of chaos by resonant parametric perturbation control methods. First of all, MATLAB/SIMULINK is used to derive a mathematical model for QR-ZCS DC-DC buck converters, and to simulate the converters to observe the waveform of output voltages, inductance currents and phase-plane portraits from the period-doubling bifurcation to chaos by changing the load resistances. Secondly, using resonant parametric perturbation control in QR-ZCS buck DC-DC converters, the simulation results of the chaotic converter form chaos state turn into stable state period 1, and improve ripple amplitudes of converters under the chaos, to verify the validity of the proposes method.

Transmit Antenna Selection for Spatial Multiplexing UWB MIMO Systems Using Sorted QR Decomposition  

NASA Astrophysics Data System (ADS)

In this letter, a post-detection signal to noise ratio (SNR) is considered for transmit antenna selection, when a sorted QR decomposition (SQRD) algorithm is used for signal detection in spatial multiplexing (SM) ultra-wideband (UWB) multiple input multiple output systems. The post-detection SNR expression is obtained using a QR factorization algorithm based on a sorted Gram-Schmidt process. The employed antenna selection criterion is to utilize the largest minimum post-detection SNR value. It is shown via simulations that the antenna selection significantly enhances the BER performance of the SQRD-based SM UWB systems on a log-normal multipath fading channel.

Development of Human-Tracking Robot by Using QR Code Recognition  

NASA Astrophysics Data System (ADS)

In this paper, we propose a human-tracking robot that can be used in some commercial establishments, such as airports and factories. Human-tracking process involves four main steps. The first step involves robust personal identification by using QR code recognition. It is the most important step in human tracking. The second step is location detection by shape-based pattern matching in order to determine the position of the QR code when the human being tracked moves far from the robot. The third step involves auxiliary re-detection by using IR cameras and retroreflectors in case that local detection is difficult in the second step. The fourth step is robot control to maintain the correct distance for human tracking. In a measurement experiment for rate of QR code recognition, it was shown that the rate of QR code recognition was 99.9% and that location detection is robust. In a robot-control experiment, it was shown that the tracking is accurate. During tracking, the robot maintains an appropriate distance from the human.

Quick clay and landslides of clayey soils.  

PubMed

We study the rheology of quick clay, an unstable soil responsible for many landslides. We show that above a critical stress the material starts flowing abruptly with a very large viscosity decrease caused by the flow. This leads to avalanche behavior that accounts for the instability of quick clay soils. Reproducing landslides on a small scale in the laboratory shows that an additional factor that determines the violence of the slides is the inhomogeneity of the flow. We propose a simple yield stress model capable of reproducing the laboratory landslide data, allowing us to relate landslides to the measured rheology. PMID:19905837

A gC1qR prevents white spot syndrome virus replication in the freshwater crayfish Pacifastacus leniusculus.  

PubMed

The gC1qR/p32 protein is a multiple receptor for several proteins and pathogens. We cloned a gC1qR homologue in a crustacean, Pacifastacus leniusculus, and analyzed the expression of P. leniusculus C1qR (PlgC1qR) in various tissues. The gC1qR/p32 transcript was significantly enhanced by white spot syndrome virus (WSSV) infection 6 h after viral infection both in vitro in a hematopoietic tissue cell culture (Hpt) and in vivo compared to appropriate controls. Moreover, PlgC1qR silencing in both the Hpt cell culture and live crayfish enhanced the WSSV replication. In addition, by making a recombinant PlgC1qR protein we could show that if this recombinant protein was injected in a crayfish, Pacifastacus leniusculus, followed by injection of WSSV, this significantly reduced viral replication in vivo. Furthermore, if the recombinant PlgC1qR was incubated with Hpt cells and then WSSV was added, this also reduced viral replication. These experiments clearly demonstrate that recombinant PlgC1qR reduce WSSV replication both in vivo and in vitro. The results from a far-Western overlay and glutathione S-transferase pull-down assays showed that PlgC1qR could bind to VP15, VP26, and VP28. Altogether, these results demonstrate a role for PlgC1qR in antiviral activity against WSSV. PMID:20686021

[Multidrug resistance p-glycoprotein inhibits the antiapoptotic action of mitochondria-targeted antioxidant SkQR1].  

PubMed

Mitochondria-targeted antioxidants of the SkQRI family, being accumulated in energized mitochondria, protect cells from oxidative stress by increasing the level of reduced glutathione and decreasing the cell-damaging effect induced by hydrogen peroxide. Using various human transformed cell lines and SkQR1 (a fluorescent member of the SkQ family), we show that SkQR1 is ejected from chemotherapy-resistant cells by P-glycoprotein--one of the main transport proteins determining multidrug resistance typical for many neoplastic cells. It is also shown that SkQR1 ejection is neutralized by P-glycoprotein inhibitors (verapamil and pluronic L61). In experiments on K562 cells, it was found that the subline sensitive to chemotherapy is protected by SkQR1 from apoptotic action of hydrogen peroxide. Protection of the resistant subline occurs only after inhibition of P-glycoprotein. PMID:21427983

Introducing the Maastricht Acute Stress Test (MAST): a quick and non-invasive approach to elicit robust autonomic and glucocorticoid stress responses.  

PubMed

Stress-related research has employed several procedures to activate the human stress system. Two of the most commonly used laboratory paradigms are the Trier Social Stress Test (TSST) and the Cold Pressor Test (CPT). We combined their most stressful features to create a simple laboratory stress test capable of eliciting strong autonomic and glucocorticoid stress responses. In comparison with the CPT and its variations, our stress tool (labeled the Maastricht Acute Stress Test; MAST) was found to yield superior salivary cortisol responses, while being equally effective in eliciting subjective stress reactions and (systolic and diastolic) blood pressure increases (study 1; N=80). In study 2 (N=20), we directly compared the effectiveness of the MAST and TSST and found that both methods elicited similar subjective, salivary alpha-amylase, and salivary cortisol stress responses. Finally, we developed and evaluated an appropriate no-stress control version of the MAST that was similar to the stress version, although it did not comprise stressful components (study 3; N=40). Collectively, our results confirm the effectiveness of the MAST in terms of subjective, autonomic, and--most importantly--glucocorticoid stress responses. Thus, as a brief and simple stress protocol, the MAST holds considerable promise for future research. PMID:22608857

Rate Control for Zero-Forcing Beamforming Multiuser MIMO Systems with QR-Decomposition MLD Receiver  

NASA Astrophysics Data System (ADS)

A rate control scheme is described for zero-forcing beamforming (ZFBF) multiuser multiple-input and multiple-output (MU-MIMO) systems with a QR-decomposition maximum likelihood detector (MLD) at the receiver. For selected users, a modulation-and-coding set is selected for each substream by estimating the per-substream post-MLD signal-to-interference-plus-noise ratio. Iterative modified QR-decomposition MLD is employed at the receiver to achieve the throughput expected from the transmitter. The simulation results demonstrated that the proposed rate-control scheme achieved the target packet error rate while increasing the throughout for ZFBF-MU-MIMO systems as the number of user candidates increases.

Out-of-Core Computation of the QR Factorization on Multi-core Processors  

NASA Astrophysics Data System (ADS)

We target the development of high-performance algorithms for dense matrix operations where data resides on disk and has to be explicitly moved in and out of the main memory. We provide strong evidence that, even for a complex operation like the QR factorization, the use of a run-time system creates a separation of concerns between the matrix computations and I/O operations with the result that no significant changes need to be introduced to existing in-core algorithms. The library developer can thus focus on the design of algorithms-by-blocks, addressing disk memory as just another level of the memory hierarchy. Experimental results for the out-of-core computation of the QR factorization on a multi-core processor reveal the potential of this approach.

Effects of q(r) on the Alpha Particle Ripple Loss in TFTR  

SciTech Connect

An experiment was done with TFTR DT plasmas to determine the effect of the q(r) profile on the alpha particle ripple loss to the outer midplane. The alpha particle loss measurements were made using a radially movable scintillator detector 20 degrees below the outer midplane. The experimental results were compared with TF ripple loss calculations done using a Monte Carlo guiding center orbit following code, ORBIT. Although some of the experimental results are consistent with the ORBIT code modeling, the variation of the alpha loss with the q(r) profiles is not well explained by this code. Quantitative interpretation of these measurements requires a careful analysis of the limiter shadowing effect, which strongly determines the diffusion of alphas into the detector aperture.

gC1qR expression in chimpanzees with resolved and chronic infection: Potential role of HCV core/gC1qR-mediated T cell suppression in the outcome of HCV infection  

SciTech Connect

Chimpanzee is a unique animal model for HCV infection, in which about 50% of infections resolve spontaneously. It has been reported that the magnitude of T cell responses to HCV core in recovered chimpanzees is greater than that in chronically infected ones. However, the mechanism(s) by which the chimpanzees with resolved infection overcome core-mediated immunosuppression remains unknown. In this study, we examined the effect of HCV core on T cell responsiveness in chimpanzees with resolved and chronic HCV infection. We found that core protein strongly inhibited T cell activation and proliferation in chimpanzees with chronic infection, while this inhibition was limited in chimpanzees with resolved infection. Notably, the level of gC1qR, as well as the binding of core protein, on the surface of T cells was lower in recovered chimpanzees when compared to chimpanzees with chronic HCV infection. Intriguingly, the observed differences in gC1qR expression levels and susceptibility to core-induced suppression amongst HCV-chronically infected and recovered chimpanzees were observed prior to HCV challenge, suggesting a possible genetic determination of the outcome of infection. These findings suggest that gC1qR expression on the surface of T cells is crucial for HCV core-mediated T cell suppression and viral clearance, and that represents a novel mechanism by which a virus usurps host machinery for persistence.

QR-STEM: Energy and Environment as a Context for Improving QR and STEM Understandings of 6-12 Grade Teachers II. The Quantitative Reasoning  

NASA Astrophysics Data System (ADS)

The Quantitative Reasoning in STEM (QR STEM) project is a state level Mathematics and Science Partnership Project (MSP) with a focus on the mathematics and statistics that underlies the understanding of complex global scientific issues. This session is a companion session to the QR STEM: The Science presentation. The focus of this session is the quantitative reasoning aspects of the project. As students move from understandings that range from local to global in perspective on issues of energy and environment, there is a significant increase in the need for mathematical and statistical conceptual understanding. These understandings must be accessible to the students within the scientific context, requiring the special understandings that are endemic within quantitative reasoning. The QR STEM project brings together interdisciplinary teams of higher education faculty and middle/high school teachers to explore complex problems in energy and environment. The disciplines include life sciences, physics, chemistry, earth science, statistics, and mathematics. These interdisciplinary teams develop open ended performance tasks to implement in the classroom, based on scientific concepts that underpin energy and environment. Quantitative reasoning is broken down into three components: Quantitative Literacy, Quantitative Interpretation, and Quantitative Modeling. Quantitative Literacy is composed of arithmetic concepts such as proportional reasoning, numeracy, and descriptive statistics. Quantitative Interpretation includes algebraic and geometric concepts that underlie the ability to interpret a model of natural phenomena which is provided for the student. This model may be a table, graph, or equation from which the student is to make predictions or identify trends, or from which they would use statistics to explore correlations or patterns in data. Quantitative modeling is the ability to develop the model from data, including the ability to test hypothesis using statistical procedures. We use the term model very broadly, so it includes visual models such as box models, as well as best fit equation models and hypothesis testing. One of the powerful outcomes of the project is the conversation which takes place between science teachers and mathematics teachers. First they realize that though they are teaching concepts that cross their disciplines, the barrier of scientific language within their subjects restricts students from applying the concepts across subjects. Second the mathematics teachers discover the context of science as a means of providing real world situations that engage students in the utility of mathematics as a tool for solving problems. Third the science teachers discover the barrier to understanding science that is presented by poor quantitative reasoning ability. Finally the students are engaged in exploring energy and environment in a manner which exposes the importance of seeing a problem from multiple interdisciplinary perspectives. The outcome is a democratic citizen capable of making informed decisions, and perhaps a future scientist.

Symplectic Householder transformations for a QR-like decomposition, a geometric and algebraic approaches  

NASA Astrophysics Data System (ADS)

The aim of this paper is to show how geometric and algebraic approaches lead us to a new symplectic elementary transformations: the 2-D symplectic Householder transformations. Their features are studied in details. Their interesting properties allow us to construct a new algorithm for computing a SR factorization. This algorithm is based only on these 2-D symplectic Householder transformations. Its new features are highlighted. The study shows that, in the symplectic case, the new algorithm is the corresponding one to the classical QR factorization algorithm, via the Householder transformations. Some numerical experiments are given.

A heat pipe quick disconnect  

NASA Astrophysics Data System (ADS)

This paper reports the proof of concept demonstration of a heat pipe quick disconnect being developed for the space constructible radiator system. The disconnect provides a maintainable coupling between the heat pipe evaporator, which is brazed to a mating heat exchanger, and the replaceable condenser section of a monogroove heat pipe radiator element. Test results, with pressurized nitrogen gas, confirm low leakage rates in both demated and mated configurations. Comparative thermal tests in a working 3 m (10 ft) test bed heat pipe using ammonia fluid revealed a 30 percent decrease in heat transport due to the additional minor pressure losses from the quick disconnect. The bulk of this loss is attributed to the transition section that joins the two adjacent heat pipe flow channels to the separated liquid and vapor passages within the disconnect coupling. It would be possible to decrease this overall loss in heat transport to under 10 percent with a redesigned transition section.

Quick-change filter cartridge  

DOEpatents

A quick-change filter cartridge. In sampling systems for measurement of airborne materials, a filter element is introduced into the sampled airstream such that the aerosol constituents are removed and deposited on the filter. Fragile sampling media often require support in order to prevent rupture during sampling, and careful mounting and sealing to prevent misalignment, tearing, or creasing which would allow the sampled air to bypass the filter. Additionally, handling of filter elements may introduce cross-contamination or exposure of operators to toxic materials. Moreover, it is desirable to enable the preloading of filter media into quick-change cartridges in clean laboratory environments, thereby simplifying and expediting the filter-changing process in the field. The quick-change filter cartridge of the present invention permits the application of a variety of filter media in many types of instruments and may also be used in automated systems. The cartridge includes a base through which a vacuum can be applied to draw air through the filter medium which is located on a porous filter support and held there by means of a cap which forms an airtight seal with the base. The base is also adapted for receiving absorbing media so that both particulates and gas-phase samples may be trapped for investigation, the latter downstream of the aerosol filter.

Two case studies: QuietRock QR-530 drywall panels in new and remediated multifamily construction  

NASA Astrophysics Data System (ADS)

Reliable acoustical isolation continues to be a high risk element of contemporary multifamily construction. Traditional construction techniques, offering potentially high acoustical performance, exist but may be compromised during typical construction or occupation. This paper presents two case studies using a new class of construction material-drywall panels employing constrained layer damping. QuietRock QR-530 damped gypsum board panels are used in a new construction project and as part of a remediation treatment. In a first study, QR-530 panels were used as a drywall alternative in a 2×6, semistaggered, framed wall separating luxury condominiums. Field evaluation per ASTM E36 revealed a normalized noise isolation class of 56. In a second case study, a single layer of QuietRock was applied directly to an existing single stud assembly in a resort hotel. Before and after testing yielded a change of 14 points, raising the noise isolation class from 36 to 50. This paper reviews the details of the test cases and the underlying physical principals of the subject materials.

20-GFLOPS QR processor on a Xilinx Virtex-E FPGA  

NASA Astrophysics Data System (ADS)

Adaptive beamforming can play an important role in sensor array systems in countering directional interference. In high-sample rate systems, such as radar and comms, the calculation of adaptive weights is a very computational task that requires highly parallel solutions. For systems where low power consumption and volume are important the only viable implementation is as an Application Specific Integrated Circuit (ASIC). However, the rapid advancement of Field Programmable Gate Array (FPGA) technology is enabling highly credible re-programmable solutions. In this paper we present the implementation of a scalable linear array processor for weight calculation using QR decomposition. We employ floating-point arithmetic with mantissa size optimized to the target application to minimize component size, and implement them as relationally placed macros (RPMs) on Xilinx Virtex FPGAs to achieve predictable dense layout and high-speed operation. We present results that show that 20GFLOPS of sustained computation on a single XCV3200E-8 Virtex-E FPGA is possible. We also describe the parameterized implementation of the floating-point operators and QR-processor, and the design methodology that enables us to rapidly generate complex FPGA implementations using the industry standard hardware description language VHDL.

Detection of circumbinary material in the galactic supersoft X-ray binary QR And  

NASA Astrophysics Data System (ADS)

In an attempt to solve the long-standing quest for the nature of the secondary star in supersoft X-ray binaries, we have obtained phase-resolved high-S/N optical-near-IR spectroscopy and high-resolution near-UV Echelle spectra of the bright galactic supersoft X-ray binary QR And (= RX J0019.8+2156). From the absence of any stellar absorption features in these data we derive a minimum distance d >~800-1300 pc of the binary system. Besides emission lines showing Doppler shifts with the binary orbit, we have detected several broad stationary emission lines which have been identified as forbidden ``coronal-like'' transitions of Fe X, O V, and N V. The material emitting these lines must be distributed axially symmetrically around the binary center of gravity, probably forming an optically thin envelope or a torus surrounding the binary system.

Adaptive multilayer method of fundamental solutions using a weighted greedy QR decomposition for the Laplace equation  

NASA Astrophysics Data System (ADS)

The mixed boundary value problem of the Laplace equation is considered. The method of fundamental solutions (MFS) approximates the exact solution to the Laplace equation by a linear combination of independent fundamental solutions with different source points. The accuracy of the numerical solution depends on the distribution of source points. In this paper, a weighted greedy QR decomposition (GQRD) is proposed to choose significant source points by introducing a weighting parameter. An index called an average degree of approximation is defined to show the efficiency of the proposed method. From numerical experiments, it is concluded that the numerical solution tends to be more accurate when the average degree of approximation is larger, and that the proposed method can yield more accurate solutions with a less number of source points than the conventional GQRD.

Detecting cancer quickly and accurately  

NASA Astrophysics Data System (ADS)

We present a new technique for high throughput screening of tumor cells in a sensitive nanodevice that has the potential to quickly identify a cell population that has begun the rapid protein synthesis and mitosis characteristic of cancer cell proliferation. Currently, pathologists rely on microscopic examination of cell morphology using century-old staining methods that are labor-intensive, time-consuming and frequently in error. New micro-analytical methods for automated, real time screening without chemical modification are critically needed to advance pathology and improve diagnoses. We have teamed scientists with physicians to create a microlaser biochip (based upon our R&D award winning bio- laser concept) which evaluates tumor cells by quantifying their growth kinetics. The key new discovery was demonstrating that the lasing spectra are sensitive to the biomolecular mass in the cell, which changes the speed of light in the laser microcavity. Initial results with normal and cancerous human brain cells show that only a few hundred cells -- the equivalent of a billionth of a liter -- are required to detect abnormal growth. The ability to detect cancer in such a minute tissue sample is crucial for resecting a tumor margin or grading highly localized tumor malignancy.

Using nitrate to quantify quick flow in a karst aquifer  

USGS Publications Warehouse

In karst aquifers, contaminated recharge can degrade spring water quality, but quantifying the rapid recharge (quick flow) component of spring flow is challenging because of its temporal variability. Here, we investigate the use of nitrate in a two-endmember mixing model to quantify quick flow in Barton Springs, Austin, Texas. Historical nitrate data from recharging creeks and Barton Springs were evaluated to determine a representative nitrate concentration for the aquifer water endmember (1.5 mg/L) and the quick flow endmember (0.17 mg/L for nonstormflow conditions and 0.25 mg/L for stormflow conditions). Under nonstormflow conditions for 1990 to 2005, model results indicated that quick flow contributed from 0% to 55% of spring flow. The nitrate-based two-endmember model was applied to the response of Barton Springs to a storm and results compared to those produced using the same model with ??18O and specific conductance (SC) as tracers. Additionally, the mixing model was modified to allow endmember quick flow values to vary over time. Of the three tracers, nitrate appears to be the most advantageous because it is conservative and because the difference between the concentrations in the two endmembers is large relative to their variance. The ??18O- based model was very sensitive to variability within the quick flow endmember, and SC was not conservative over the timescale of the storm response. We conclude that a nitrate-based two-endmember mixing model might provide a useful approach for quantifying the temporally variable quick flow component of spring flow in some karst systems. ?? 2008 National Ground Water Association.

Pre-Whitening QR-Decomposition Maximum Likelihood Detection for Co-channel Interference Rejection in MIMO Systems  

NASA Astrophysics Data System (ADS)

We describe a co-channel interference rejection scheme that is suitable for QR-decomposition maximum likelihood detection (MLD) in multiple-input and multiple output (MIMO) systems. A pre-whitening matrix for interference rejection is decomposed into a triangular matrix and its Hermitian matrix by using a complex Gaxpy version of the Cholesky algorithm. The decomposed triangular matrix is used as a spatial pre-filter to whiten co-channel interference. Simulation results demonstrate that the proposed scheme can suppress co-channel interference streams at the cost of receive diversity order and achieves better transmission performance than QR-decomposition MLD itself in MIMO channels with co-channel interference.

A modified QuickDASH-9 provides a valid outcome instrument for upper limb function  

PubMed Central

Background The 30-item Disabilities Arm Shoulder and Hand (DASH) questionnaire was introduced to facilitate assessment of upper limb functional limitations. To improve practicality and eliminate item redundancy a modified instrument was needed. The 11-item QuickDASH was developed to fulfil these requirements and translated into several languages. However, prospective investigations of psychometric and practical characteristics are limited. No published study investigated readability or used concurrent validation with a standardized upper limb criterion measure. The validity of the QuickDASH has been questioned as the results for factor structure are conflicting, and the English-language version has not yet had factor structure reported. A shortened 9-item version, the QuickDASH-9, that addresses these issues is proposed. Methods This two-stage observational study assessed the psychometric and practical characteristics of the QuickDASH and the extracted QuickDASH-9. The Upper Limb Functional Index (ULFI) was the criterion standard in both stages. Stage 1, calibration, reanalyzed extracted QuickDASH and QuickDASH-9 responses from a previous prospective study, by the authors, of the 30-item DASH (n = 137). Stage 2, prospective validation, investigated the QuickDASH through repeated measures in consecutive upper limb musculoskeletal participants' consulting for physical therapy in Australia (n = 67). The QuickDASH and extracted QuickDASH-9 data from both stages was analyzed and compared for psychometric properties, practical characteristics and factor structure. Results The proposed QuickDASH-9 had a unidimensional structure, high reliability (ICC 2:1, r = 0.92), internal consistency (alpha = 0.93) and responsiveness (ES = 1.05). It correlated highly with both the DASH (r = 0.97), QuickDASH (r = 0.99) and ULFI criterion (r = 0.85). QuickDASH-9 missing responses reduced to 3.5% from 26% in the QuickDASH. Completion and scoring time was 134 ± 56 seconds and required a computational aid. The QuickDASH demonstrated a bidimensional structure making it invalid. The QuickDASH-9 summary performance was measured on the 'Measurement of Outcome Measures' at 88% and on the 'Bot' clinimetric scale at 75%. Conclusions The proposed QuickDASH-9 had a unidimensional structure and similar psychometric precision to the full-length DASH with improved practicality and completion time. The QuickDASH was invalid as its bidimensional structure made a single summated score inappropriate. The QuickDASH-9 offers a future direction for ongoing use of the QuickDASH concept.

This letter describes a new QR-decomposition maximum likelihood detector that is combined with frequency-domain equalization for single-carrier transmission based multiple-input multiple-output systems. By utilizing the equalized substreams to adjust the frequency selectivity in corresponding substreams in subsequent stages, the packet error rate performances of the proposed detector is superior to that of the minimum mean squared error receiver by a factor of the receive antenna diversity gain.

Phytochemical analysis of the triterpenoids with cytotoxicity and QR inducing properties from the total tea seed saponin of Camellia sinensis.  

PubMed

The tea seed triterpene saponin (TS) from Camellia sinensis was found to exhibit better antitumor activity in vivo in S180 implanted ICR mice and QR inducing activity for hepa lclc7 cells respectively compared with the total tea seed saponin (TTS), hydrolysate of the TTS and tea seed flavonoid glycosides (TF). By bioassay-guided isolation, the TS fraction was separated and seven major components were purified and identified as theasaponin E1 (1), theasaponin E2 (2), theasaponin C1 (3), assamsaponin C (4), theasaponin H1 (5), theasaponin A9 (6), and theasaponin A8 (7), among which compounds 4 and 5 were isolated from this genus for the first time. The antitumor bioassay of the isolated compounds showed that compounds 1, 2 and 3 exhibited potential activities against the human tumor cell lines K562 and HL60. Furthermore, compound 1 (the major constituent with a mass content of over 1%) showed significant QR inducing activity with an IR value of 4.2 at 4?g/ml. So it can be concluded that tea seed especially the compound 1 (theasaponin E1) could be used as an antitumor agent and a chemoprevention agent of cancer. The preliminary structure-activity relationship in the anti-tumor activity and QR inducing activity of tea saponins was discussed briefly. PMID:23266730

Efficient GOCE satellite gravity field recovery based on least-squares using QR decomposition  

NASA Astrophysics Data System (ADS)

We develop and apply an efficient strategy for Earth gravity field recovery from satellite gravity gradiometry data. Our approach is based upon the Paige-Saunders iterative least-squares method using QR decomposition (LSQR). We modify the original algorithm for space-geodetic applications: firstly, we investigate how convergence can be accelerated by means of both subspace and block-diagonal preconditioning. The efficiency of the latter dominates if the design matrix exhibits block-dominant structure. Secondly, we address Tikhonov-Phillips regularization in general. Thirdly, we demonstrate an effective implementation of the algorithm in a high-performance computing environment. In this context, an important issue is to avoid the twofold computation of the design matrix in each iteration. The computational platform is a 64-processor shared-memory supercomputer. The runtime results prove the successful parallelization of the LSQR solver. The numerical examples are chosen in view of the forthcoming satellite mission GOCE (Gravity field and steady-state Ocean Circulation Explorer). The closed-loop scenario covers 1 month of simulated data with 5 s sampling. We focus exclusively on the analysis of radial components of satellite accelerations and gravity gradients. Our extensions to the basic algorithm enable the method to be competitive with well-established inversion strategies in satellite geodesy, such as conjugate gradient methods or the brute-force approach. In its current development stage, the LSQR method appears ready to deal with real-data applications.

Observation of PL intensity modulation in self-assembled Quantum Rings (QR) under strong pulsed magnetic fields  

NASA Astrophysics Data System (ADS)

We present photoluminescence (PL) measurements of self-assembled In(Ga)As QRs in strong pulsed magnetic fields. The results show a striking modulation of the intensity. This modulation of the emission can be attributed to an effect predicted by Govorov et al.: a mechanism for the topological phase of a neutral particle, a polarized exciton confined to a semiconductor quantum ring. The magnetic-field induced phase strongly affects the excitons in the QR, resulting in switching between bright exciton ground states and novel dark states.

Least squares QR-based decomposition provides an efficient way of computing optimal regularization parameter in photoacoustic tomography  

NASA Astrophysics Data System (ADS)

A computationally efficient approach that computes the optimal regularization parameter for the Tikhonov-minimization scheme is developed for photoacoustic imaging. This approach is based on the least squares-QR decomposition which is a well-known dimensionality reduction technique for a large system of equations. It is shown that the proposed framework is effective in terms of quantitative and qualitative reconstructions of initial pressure distribution enabled via finding an optimal regularization parameter. The computational efficiency and performance of the proposed method are shown using a test case of numerical blood vessel phantom, where the initial pressure is exactly known for quantitative comparison.

GluA2 AMPA glutamate receptor subunit exhibits codon 607 Q/R RNA editing in the lens  

PubMed Central

Regulated GluA2 AMPA subunit expression, RNA editing, and membrane localization are fundamental determinants of neuronal Ca2+ influx, and underlie basic functions such as memory and the primary brain disorder epilepsy. Consistent with this, AMPARs, and specifically GluA2, are targets of common antiepileptic drugs (AEDs) and antidepressants. Recently, epidemiological associations between epilepsy and increased cataract prevalence were found comparable to cataract links with diabetes and smoking. Similarly, use of AEDs and several antidepressants also showed links with increased cataract. Here, we demonstrated GluA2 in lenses, consistent with REST/NRSF and REST4 we described previously in lenses, as well as GluA1 and ADAR2 in the lens. Surprisingly, we found predominant neuron-like Q/R editing of GluA2 RNAs also occurs in the lens and evidence of lens GluA2 phosphorylation and STEP phosphatases linked with GluA2 membrane localization in neurons. This study is among the first to show GluA2 expression and predominant Q/R RNA editing in a non-neural cell. Our results suggest GluA2 AMPARs have related roles in lens physiology and disease processes, and provide evidence these anticonvulsant and antidepressant drug targets also occur in the lens.

["Quick Return Service" of the surgical pathology].  

PubMed

The "Quick Return Service" of laboratory information would be the service for patients and clinicians that supply the laboratory information the instance that the specimens and the requests of laboratory examinations are accepted by the laboratory on the basis of the hospital information system (HIS) and the high-speed hospital transportation system of the specimens. Is the "Quick Return Service" of the pathological diagnosis possible and necessary? This question led the author to review the technical environments of the pathological diagnosis, especially of the frozen section diagnosis through our experience at the surgical pathology division of the Department of Laboratory Medicine of National Defense Medical College (NDMC) Hospital. Through the review, it appears that the supporting system for surgical pathologists to frozen section diagnosis ("Quick Return Service") is essential. Pathologists often need clinical and radiological information at the pathological diagnosis. For quick gaining of the information by surgical pathologists on the "Quick Return Service", the efficient HIS including hospital PACS (picture archiving and communication system) is necessary. Standardization and quality assurance of images of frozen section are also necessary. The technical environments of telepathology are developing. The interinstitution consultation through the telepathology will be the indispensable help for the "general" surgical pathologists confronting the problematic cases in the small hospitals that are deficient of pathologists. With the help of staff of the surgical pathology division of the NDMC hospital and the technologists of Mitsubishi Electronics, Co, the author has tried to develop the archiving system of frozen section pictures on the digital image management system.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:8531383

This is the first time that a high yield of (R)-3-quinuclidinol up to 916 g L(-1) d(-1) using a bioreduction approach is reported. PMID:24050153

Sarcomere Length and Tension Changes in Tetanized Frog Muscle Fibers after Quick Stretches and Releases  

NASA Astrophysics Data System (ADS)

The sarcomere length changes in tetanized frog muscle fibers in response to quick fiber length changes were examined along the fiber length with a high-sensitivity laser diffraction technique. The experiments were only performed with muscle fibers in which the uniform orientation and sarcomere length of the component myofibrils were well preserved during a tetanus. When the sarcomere length changes were recorded near the fixed fiber end, the delay of the onset of sarcomere length change in response to the applied fiber length change tended to be longer than that of the onset of tension changes recorded at the fixed fiber end. The magnitude of sarcomere length changes was larger near the moving fiber end than near the fixed fiber end. In the case of quick releases, the resulting sarcomere shortening tended to outlast the fiber shortening, so that the quick tension recovery started during the sarcomere shortening. These results indicate (i) that the tension changes in response to quick fiber length changes may not give direct information about the cross-bridge properties and (ii) that the viscoelastic multisegmental nature of muscle fibers should be taken into consideration in interpreting the tension responses to quick length changes.

Physiological Environment Induces Quick Response - Slow Exhaustion Reactions  

PubMed Central

In vivo environments are highly crowded and inhomogeneous, which may affect reaction processes in cells. In this study we examined the effects of intracellular crowding and an inhomogeneity on the behavior of in vivo reactions by calculating the spectral dimension (ds), which can be translated into the reaction rate function. We compared estimates of anomaly parameters obtained from fluorescence correlation spectroscopy (FCS) data with fractal dimensions derived from transmission electron microscopy (TEM) image analysis. FCS analysis indicated that the anomalous property was linked to physiological structure. Subsequent TEM analysis provided an in vivo illustration; soluble molecules likely percolate between intracellular clusters, which are constructed in a self-organizing manner. We estimated a cytoplasmic spectral dimension ds to be 1.39?±?0.084. This result suggests that in vivo reactions initially run faster than the same reactions in a homogeneous space; this conclusion is consistent with the anomalous character indicated by FCS analysis. We further showed that these results were compatible with our Monte-Carlo simulation in which the anomalous behavior of mobile molecules correlates with the intracellular environment, leading to description as a percolation cluster, as demonstrated using TEM analysis. We confirmed by the simulation that the above-mentioned in vivo like properties are different from those of homogeneously concentrated environments. Additionally, simulation results indicated that crowding level of an environment might affect diffusion rate of reactant. Such knowledge of the spatial information enables us to construct realistic models for in vivo diffusion and reaction systems.

Far-Ultraviolet Observations of the Galactic Supersoft Binary RX J0019.8+2156 (QR Andromedae)  

NASA Astrophysics Data System (ADS)

Far-Ultraviolet Spectroscopic Explorer spectra were obtained of the supersoft X-ray binary RX J0019.8+2156 (QR And) during 16 consecutive spacecraft orbits, covering the binary orbit (P=15.85 hr) with about 0.2 phase overlap. The spectrum is dominated by strong H2 absorption (column density ~1020 g cm-2), which appears at the velocity different from other interstellar absorption lines and may be partially circumbinary. This absorption makes study of spectral features from the binary system difficult. The only well-detected emission lines are He II ?1085 and O VI ?1032 (the other line of the O VI doublet, at 1037 Å, is largely obscured by strong H2 absorption). The O VI shows a P Cygni profile that varies in velocity and strength with binary phase. We compare this with similar changes seen in Balmer line profiles. We extract the far-ultraviolet (FUV) light curve and compare it with the optical light curve. There is an eclipse in both wavelength regions, but the FUV minimum lasts much longer, well beyond the visible light egress. The FUV results are discussed in connection with the binary model and mass flows within the system. Based on observations made with the NASA-CNES-CSA Far Ultraviolet Spectroscopic Explorer. FUSE is operated for NASA by Johns Hopkins University under NASA contract NAS 5-3298

Simultaneous Photometry and Spectroscopy of the Supersoft X-Ray Source RX J0019.8+2156 (QR Andromedae)  

NASA Astrophysics Data System (ADS)

Simultaneous optical photometry and spectroscopy of QR Andromedae (RX J0019.8+2156) obtained in 1995 are reported. The V light curve shows a range of ~0.5 mag through the 15.85 hr orbital period, with shorter term (~1.8 hr) variations superposed. There is no clear indication of any color change through the orbit. The spectra show strong emission lines, principally due to He II, which vary in both velocity and strength throughout the orbit. Violet-displaced H absorption lines are present during about half the orbital cycle. Emission lines of O VI (?3811, ?3834) are clearly present. Two higher dispersion spectra also reveal emission lines of O V, C III, C IV, N III, N V, [Fe X], and [Fe XIV]. A few moderate-strength emission lines remain unidentified. Analysis of the radial velocity variations and light curve show the donor star to be a very low mass object (0.3-0.5 Msolar), assuming the compact star's mass lies below ~1.5 Msolar. A search for spectral variations associated with the short-term photometric flickering reveals no obvious correlations, but our spectra have rather low resolution and signal-to-noise ratio. Supplemental photometry taken in 2000 July allows us to derive an improved orbital ephemeris for the system.

Steric antisense inhibition of AMPA receptor Q/R editing reveals tight coupling to intronic editing sites and splicing  

PubMed Central

Adenosine-to-Inosine (A-to-I) RNA editing is a post-transcriptional mechanism, evolved to diversify the transcriptome in metazoa. In addition to wide-spread editing in non-coding regions protein recoding by RNA editing allows for fine tuning of protein function. Functional consequences are only known for some editing sites and the combinatorial effect between multiple sites (functional epistasis) is currently unclear. Similarly, the interplay between RNA editing and splicing, which impacts on post-transcriptional gene regulation, has not been resolved. Here, we describe a versatile antisense approach, which will aid resolving these open questions. We have developed and characterized morpholino oligos targeting the most efficiently edited site—the AMPA receptor GluA2 Q/R site. We show that inhibition of editing closely correlates with intronic editing efficiency, which is linked to splicing efficiency. In addition to providing a versatile tool our data underscore the unique efficiency of a physiologically pivotal editing site.

Equilibrium flash calculations quickly computed on PC  

SciTech Connect

Equilibrium flash calculations can be computed quickly by an interactive Fortran program developed for personal computers. The program determines the equilibrium separation of a stream for multicomponent mixtures in oil, gas, and chemical processes, resulting in a liquid-vapor equilibrium mixture. Results are obtained much faster than with previously published programs. Flash vaporization calculations involving multicomponent mixtures are essential to the design and successful operation of many processes. These calculations are often required to determine the condition of the feed to a fractionation column or to determine the flow of vapor from a reboiler or condensor. Flash calculations often involve trial-and-error solutions which are time consuming, tedious, and subject to error if performed manually. Previous calculation procedures involved the use of programmable calculators which, with the growing use of personal computers, are becoming obsolete. This paper lists ways of producing two-phase mixtures from a single phase at appropriate conditions. The last process in the table typifies the well-head separation that takes place in an oil field. It is termed a flash process because vapor forms as a result of rapidly dropping the pressure.

Quick management of accidental tritium exposure cases.  

PubMed

Removal half-life (RHL) of tritium is one of the best means for optimising medical treatment, reduction of committed effective dose (CED) and quick/easy handling of a large group of workers for medical treatment reference. The removal of tritium from the body depends on age, temperature, relative humidity and daily rainfall; so tritium removal rate, its follow-up and proper data analysis and recording are the best techniques for management of accidental acute tritium exposed cases. The decision of referring for medical treatment or medical intervention (MI) would be based on workers' tritium RHL history taken from their bodies at the facilities. The workers with tritium intake up to 1 ALI shall not be considered for medical treatment as it is a derived limit of annual total effective dose. The short-term MI may be considered for tritium intake of 1-10 ALI; however, if the results show intake ?100 ALI, extended strong medical/therapeutic intervention may be recommended based on the severity of exposure for maximum CED reduction requirements and annual total effective dose limit. The methodology is very useful for pressurized heavy water reactors (PHWRs) which are mainly operated by Canada and India and future fusion reactor technologies. Proper management will optimise the cases for medical treatment and enhance public acceptance of nuclear fission and fusion reactor technologies. PMID:22349318

Comparison of the main sequence of reflexive saccades and the quick phases of optokinetic nystagmus  

PubMed Central

BACKGROUND/AIMS—Abnormalities in the saccadic main sequence are an important finding and may indicate pathology of the ocular motor periphery or central neurological disorders. In young or uncooperative patients it can be difficult eliciting a sufficient number of saccades to measure the main sequence. It is often assumed that the quick phases of optokinetic nystagmus (OKN) are identical to saccades. If this were the case, it would be feasible to use OKN, an involuntary response that is easily evoked, as a simple way of eliciting many saccades. The aim of this study was to determine whether reflexive saccades and the quick phases of OKN are indeed identical, and whether OKN quick phases could have a clinical role in identifying patients with slow saccades.?METHODS—OKN and reflexive saccades were recorded from 10 healthy adults using an infrared limbus eye tracker and bitemporal DC electro-oculography simultaneously. OKN was stimulated by rotating a full field patterned curtain around the subject at 10-50°/s. Reflexive saccades were elicited to red LED targets at 5-20° eccentricity.?RESULTS—OKN quick phases tended to have a longer duration compared to saccades, but these differences were not significant. OKN quick phases had a slightly lower peak velocity compared to saccades, which was statistically significant (p<0.05).?CONCLUSION—The main sequence for duration is the same for reflexive saccades and OKN quick phases. The main sequence for peak velocity is slightly faster for reflexive saccades than OKN quick phases, but the difference is unlikely to be of clinical significance. As an illustration of the potential of this technique, the authors demonstrate that OKN quick phases show similar slowness to saccades in a child with brainstem pathology caused by Gaucher disease type III. It is concluded that recording OKN may be a simple clinical means for approximating the main sequence.??

Retargeting of the mitochondrial protein p32/gC1Qr to a cytoplasmic compartment and the cell surface.  

PubMed

p32/gC1qR is a small acidic protein that has been reported to have a broad range of distinct functions and to associate with a wide array of cellular, viral and bacterial proteins. It has been found in each of the main cellular compartments including mitochondria, nucleus and cytoplasm and is also thought to be located at the plasma membrane and secreted into the extracellular matrix. The true physiological role(s) of p32 remains controversial because it has been difficult to reconcile all of the findings on protein interactions and the seemingly disparate observations on compartmentalisation. However, it has been proposed that p32 is somehow involved in transport processes connecting diverse cellular compartments and the cell surface. Here we show that native p32 appears to be localised mainly in the mitochondria and is not detectable on the cell surface. However, addition of a short tag to the N-terminus of p32 appears to block its mitochondrial targeting, resulting in redirection into a cytoplasmic vesicular pattern, overlapping with the endoplasmic reticulum. The redirection of p32 results in an alteration in and co-localisation with ER markers including calreticulin, a lumenal ER chaperone. Furthermore, we show both by immunofluorescence and cross-linking studies that this also results in cell-surface expression of p32. These results indicate that, at least under certain circumstances, p32 can be retargeted and may help to provide an explanation for the diverse observations on its localization. PMID:11493647

Quick profile-reoriganization driven by helical field perturbation for suppressing tokamak major disruptions  

NASA Astrophysics Data System (ADS)

Disruptive behavior of magnetic field configuration leading to tokamak major disruption is found to be controlled by a mild mini-disruption which is induced by the compact external modular multipole-field coils with m=3/n=2 dominant helical field component in the JIPP T-IIU tokamak. This mini-disruption ergodizes the m=2/n=1 magnetic island quickly but mildly and then prevents the profile of electron temperature from flattening. This quick profile-reorganization is effective to avoid the two-step disruption (pre- and major disruptions) responsible for the catastrophic current termination.

Induced loss of ADAR2 engenders slow death of motor neurons from Q/R site-unedited GluR2.  

PubMed

GluR2 is a subunit of the AMPA receptor, and the adenosine for the Q/R site of its pre-mRNA is converted to inosine (A-to-I conversion) by the enzyme called adenosine deaminase acting on RNA 2 (ADAR2). Failure of A-to-I conversion at this site affects multiple AMPA receptor properties, including the Ca(2+) permeability of the receptor-coupled ion channel, thereby inducing fatal epilepsy in mice (Brusa et al., 1995; Feldmeyer et al., 1999). In addition, inefficient GluR2 Q/R site editing is a disease-specific molecular dysfunction found in the motor neurons of sporadic amyotrophic lateral sclerosis (ALS) patients (Kawahara et al., 2004). Here, we generated genetically modified mice (designated as AR2) in which the ADAR2 gene was conditionally targeted in motor neurons using the Cre/loxP system. These AR2 mice showed a decline in motor function commensurate with the slow death of ADAR2-deficient motor neurons in the spinal cord and cranial motor nerve nuclei. Notably, neurons in nuclei of oculomotor nerves, which often escape degeneration in ALS, were not decreased in number despite a significant decrease in GluR2 Q/R site editing. All cellular and phenotypic changes in AR2 mice were prevented when the mice carried endogenous GluR2 alleles engineered to express edited GluR2 without ADAR2 activity (Higuchi et al., 2000). Thus, loss of ADAR2 activity causes AMPA receptor-mediated death of motor neurons. PMID:20826656

Urban mockingbirds quickly learn to identify individual humans  

PubMed Central

Practically all animals are affected by humans, especially in urban areas. Although most species respond negatively to urbanization, some thrive in human-dominated settings. A central question in urban ecology is why some species adapt well to the presence of humans and others do not. We show that Northern Mockingbirds (Mimus polyglottos) nesting on the campus of a large university rapidly learn to assess the level of threat posed by different humans, and to respond accordingly. In a controlled experiment, we found that as the same human approached and threatened a nest on 4 successive days, mockingbirds flushed from their nest at increasingly greater distances from that human. A different human approaching and threatening the nest identically on the fifth day elicited the same response as the first human on the first day. Likewise, alarm calls and attack flights increased from days 1–4 with the first human, and decreased on day 5 with the second human. These results demonstrate a remarkable ability of a passerine bird to distinguish one human from thousands of others. Also, mockingbirds learned to identify individual humans extraordinarily quickly: after only 2 30-s exposures of the human at the nest. More generally, the varying responses of mockingbirds to intruders suggests behavioral flexibility and a keen awareness of different levels of threat posed by individuals of another species: traits that may predispose mockingbirds and other species of urban wildlife to successful exploitation of human-dominated environments.

Deleted Residuals, the QR-Factored Newton Iteration, and Other Methods for Formally Overdetermined Determinate Discretizations of Nonlinear Eigenproblems for Solitary, Cnoidal, and Shock Waves  

NASA Astrophysics Data System (ADS)

Solitary waves, cnoidal waves, and shock waves can be computed by solving a nonlinear eigenvalue problem, which in discretized form is a system of nonlinear algebraic equations. Unfortunately, many such systems are singular because the solution is not unique until one or more additional constraints are imposed. For example, if the waves are translationally invariant and u(X) is a solution, then so also is u(X+?) for arbitrary ?. To obtain a unique solution, one must impose an additional condition to reduce the one-parameter family of solutions by constraining ?. We describe five methods for coping with such singular systems: (i) reformulation of the problem, (ii) deleting residuals, (iii) Keller's bordered matrix scheme, (iv) QR-factored, overdetermined Newton iteration, and (v) pseudoinverse-Newton iteration. We illustrate these ideas using the cnoidal waves of the Korteweg-de Vries equation, the traveling shocks of the Korteweg-de Vries-Burgers equation, and the weakly nonlocal solitary waves of the nonlinear equatorial beta-plane equations. Finite difference, Fourier and rational Chebyshev pseudospectral methods, and spectrally upgraded finite differences are applied. Reformulation and deleting residuals are the cheapest strategies, but the QR-factored Newton iteration is needed for the shock waves, which lack the symmetry of the other two wave species. .

Clinical validation of the quick dynamic insulin sensitivity test.  

PubMed

The quick dynamic insulin sensitivity test (DISTq) can yield an insulin sensitivity result immediately after a 30-min clinical protocol. The test uses intravenous boluses of 10 g glucose and 1 U insulin at t = 1 and 11 min, respectively, and measures glucose levels in samples taken at t = 0, 10, 20, and 30 min. The low clinical cost of the protocol is enabled via robust model formulation and a series of population-derived relationships that estimate insulin pharmacokinetics as a function of insulin sensitivity (SI). Fifty individuals underwent the gold standard euglycaemic clamp (EIC) and DISTq within an eight-day period. SI values from the EIC and two DISTq variants (four-sample DISTq and two-sample DISTq30) were compared with correlation, Bland-Altman and receiver operator curve analyses. DISTq and DISTq30 correlated well with the EIC [R = 0.76 and 0.75, and receiver operator curve c-index = 0.84 and 0.85, respectively]. The median differences between EIC and DISTq/DISTq30 SI values were 13% and 22%, respectively. The DISTq estimation method predicted individual insulin responses without specific insulin assays with relative accuracy and thus high equivalence to EIC SI values was achieved. DISTq produced very inexpensive, relatively accurate immediate results, and can thus enable a number of applications that are impossible with established SI tests. PMID:23232364

Production and characterization of a murine monoclonal IgM antibody to human C1q receptor (C1qR)  

SciTech Connect

A hybridoma cell line that produces a monoclonal antibody (MAb) to cell surface C1q receptor (C1qr) has been produced by fusion of the P3 x 63-Ag8.653 mouse myeloma cell line with the spleen cells of a CD-1 mouse that had been hyperimmunized with viable Raji cell suspensions (5 x 10/sup 7/ cells/inoculum). This MAb, designated II1/D1, is an IgM antibody with lambda-light chain specificity. Radiolabeled or unlabeled, highly purified II1/D1 was used to determine that: a) this antibody competes for C1q binding sites on C1qR-bearing cells; b) the molecule recognized by this MAb is the C1qR; and c) cells that are known to bind C1q also bind II1/D1 in a specific manner. Western blot analysis of solubilized Raji, or U937 cell membranes, showed that the /sup 125/I-MAb detected a major protein band of approximately 85000 m.w. in its unreduced state, indicating that the C1qR is similar, if not identical, in both types of cells. Analyses of /sup 125/I-II/D1 binding experiments revealed that the antibody bound to Raji cells or u937 cells in a specific manner. Uptake of the antibody was saturable, with equilibrium virtually attained within 35 min. Scatchard analysis of the binding data using the intact MAb suggests that the affinity constant K/sub D/ is 2.9 x 10/sup -10/ M, and at apparent saturation, 24.6 ng of the antibody were bound per 2 x 10/sup 6/ cells, giving an estimated 7.8 x 10/sup 3/ antibody molecules bound per cell. That the II1/D1 antibody is specifically directed to the C1q was further evidenced by an ELISA in which the ability of C1qR-bearing cells to bind the MAb was abrogated by c-C1q in a specific dose-dependent manner.

RNA editing of the Q/R site of GluA2 in different cultured cell lines that constitutively express different levels of RNA editing enzyme ADAR2.  

PubMed

Adenosine deaminase acting on RNA 2 (ADAR2) catalyzes RNA editing at the glutamine/arginine (Q/R) site of GluA2, and an ADAR2 deficiency may play a role in the death of motor neurons in ALS patients. The expression level of ADAR2 mRNA is a determinant of the editing activity at the GluA2 Q/R site in human brain but not in cultured cells. Therefore, we investigated the extent of Q/R site-editing in the GluA2 mRNA and pre-mRNA as well as the ADAR2 mRNA and GluA2 mRNA and pre-mRNA levels in various cultured cell lines. The extent of the GluA2 mRNA editing was 100% except in SH-SY5Y cells, which have a much lower level of ADAR2 than the other cell lines examined. The ADAR2 activity at the GluA2 pre-mRNA Q/R site correlated with the ADAR2 mRNA level relative to the GluA2 pre-mRNA. SH-SY5Y cells expressed higher level of the GluA2 mRNA in the cytoplasm compared with other cell lines. These results suggest that the ADAR2 expression level reflects editing activity at the GluA2 Q/R site and that although the edited GluA2 pre-mRNA is readily spliced, the unedited GluA2 pre-mRNA is also spliced and transported to the cytoplasm when ADAR2 expression is low.

NeQuick bottomside analysis at low latitudes  

NASA Astrophysics Data System (ADS)

NeQuick ionospheric electron density model produces the full electron density profile in the ionosphere using the F2 layer peak values (foF2 and hmF2) as anchor points. Each part of the profile is modeled using Epstein layer formalism. Simple empirical relations are used to compute the thicknesses of each semi-Epstein layer. It has been observed that when NeQuick model is used to estimate total electron content at low latitudes the modeled values tend to underestimate the observed ones. Beside the F2 peak values, the most important profile parameter is the thickness of the F2 layer bottomside. The present study focuses on NeQuick model behavior at low latitudes comparing modeled profiles parameters with the ones extracted from experimental data mostly from African and Indian sector at different levels of solar activity and different time of the day. Possible model improvements are discussed.

Low and equatorial latitudes topside in NeQuick  

NASA Astrophysics Data System (ADS)

The NeQuick electron density model of the ionosphere is designed for trans-ionospheric propagation applications. The model topside has been revised on the basis of ISIS 2 topside sounder profiles, producing a new formulation of its empirical shape parameter. Comparisons between experimental slant TEC data and values modelled using both versions of NeQuick topside showed that in general we have obtained a distinct improvement. However, during some months of the year and at low latitudes, the new topside formulation does not produce improvements on the slant TEC estimates. We discuss the likely reasons for this behaviour including assessment of merits and shortcomings of the ISIS 2 data in low latitudes. The topside sounder on Intercosmos 19 satellite extensively sounded the equatorial region during a period of high solar activity, which was less covered by ISIS 2. This paper presents comparisons of NeQuick and topside sounders profiles at low latitudes using Intercosmos 19 satellite data.

Reliability and Frequency Response of Excitatory Signals Transmitted to Different Types of Retinal Ganglion Cell  

PubMed Central

The same visual stimulus evokes a different pattern of neural signals each time the stimulus is presented. Because this unreliability reduces visual performance, it is important to understand how it arises from neural circuitry. We asked whether different types of ganglion cell receive excitatory signals with different reliability and frequency content and, if so, how retinal circuitry contributes to these differences. If transmitter release is governed by Poisson statistics, the SNR of the postsynaptic currents (ratio of signal power to noise power) should grow linearly with quantal rate (qr), a prediction that we confirmed experimentally. Yet ganglion cells of the same type receive quanta at different rates. Thus to obtain a measure of reliability independent of quantal rate, we calculated the ratio SNR/qr, and found this measure to be type-specific. We also found type-specific differences in the frequency content of postsynaptic currents, although types whose dendrites branched at nearby levels of the inner plexiform layer (IPL) had similar frequency content. As a result, there was an orderly distribution of frequency response through the depth of the IPL, with alternating layers of broadband and high-pass signals. Different types of bipolar cell end at different depths of the IPL and provide excitatory synapses to ganglion cell dendrites there. Thus these findings indicate that a bipolar cell synapse conveys signals whose temporal message and reliability (SNR/qr) are determined by neuronal type. The final SNR of postsynaptic currents is set by the dendritic membrane area of a ganglion cell, which sets the numbers of bipolar cell synapses and thus the rate at which it receives quanta [SNR = qr × (SNR/qr)].

The cytoplasmic tail peptide sequence of membrane type-1 matrix metalloproteinase (MT1-MMP) directly binds to gC1qR, a compartment-specific chaperone-like regulatory protein.  

PubMed

Membrane type-1 matrix metalloproteinase (MT1-MMP), a key enzyme in cell locomotion, is known to be primarily recruited to the leading edge of migrating cells. This raises a possibility that the C-terminal cytoplasmic tail of MT1-MMP interacts with intracellular regulatory proteins, which modulate translocations of the protease across the cell. Here, we demonstrated that MT1-MMP via its cytoplasmic tail directly associates with a chaperone-like compartment-specific regulator gC1qR. Although a direct functional link between these two proteins remains uncertain, our observations suggest that the transient associations of gC1qR with the cytoplasmic tail of MT1-MMP are likely to be involved in the mechanisms regulating presentation of the protease at the tumor cell surface.

Searching through photographic databases with QuickLook  

NASA Astrophysics Data System (ADS)

We present here the results obtained by including a new image descriptor, that we called prosemantic feature vector, within the framework of QuickLook2 image retrieval system. By coupling the prosemantic features and the relevance feedback mechanism provided by QuickLook2, the user can move in a more rapid and precise way through the feature space toward the intended goal. The prosemantic features are obtained by a two-step feature extraction process. At the first step, low level features related to image structure and color distribution are extracted from the images. At the second step, these features are used as input to a bank of classifiers, each one trained to recognize a given semantic category, to produce score vectors. We evaluated the efficacy of the prosemantic features under search tasks on a dataset provided by Fratelli Alinari Photo Archive.

Temporally-regulated quick activation and inactivation of Ras is important for olfactory behaviour  

PubMed Central

Responses to environmental stimuli are mediated by the activation and inactivation of various signalling proteins. However, the temporal dynamics of these events in living animals are not well understood. Here we show real-time imaging of the activity of the key regulator of the MAP kinase pathway, Ras, in living Caenorhabditis elegans and that Ras is transiently activated within a few seconds in olfactory neurons in response to increase in the concentration of odorants. This fast activation of Ras is dependent on the olfactory signalling pathway and Ras guanyl nucleotide-releasing protein (RasGRP). A negative feedback loop then quickly leads to Ras inactivation despite the continued presence of the odorant. Phenotypes of Ras mutants suggest this rapid activation and inactivation of Ras is important for regulation of interneuron activities and olfactory behaviours. Our results reveal novel kinetics and biological implication of transient activation of Ras in olfactory systems.

Adaptive Selection of Surviving Symbol Replica Candidates for Quasi-Maximum Likelihood Detection Using M-Algorithm with QR-Decomposition for OFDM MIMO Multiplexing  

NASA Astrophysics Data System (ADS)

This paper proposes an adaptive selection algorithm for the surviving symbol replica candidates (ASESS) based on the maximum reliability in maximum likelihood detection with QR decomposition and the M-algorithm (QRM-MLD) for Orthogonal Frequency Division Multiplexing (OFDM) multiple-input multiple-output (MIMO) multiplexing. In the proposed algorithm, symbol replica candidates newly-added at each stage are ranked for each surviving symbol replica from the previous stage using multiple quadrant detection. Then, branch metrics are calculated only for the minimum number of symbol replica candidates with a high level of reliability using an iterative loop based on symbol ranking results. Computer simulation results show that the computational complexity of the QRM-MLD employing the proposed ASESS algorithm is reduced to approximately 1/4 and 1/1200 compared to that of the original QRM-MLD and that of the conventional MLD with squared Euclidian distance calculations for all symbol replica candidates, respectively, assuming the identical achievable average packet error rate (PER) performance in 4-by-4 MIMO multiplexing with 16QAM data modulation. The results also show that 1-Gbps throughput is achieved at the average received signal energy per bit-to-noise power spectrum density ratio (Eb/N0) per receiver antenna of approximately 9dB using the ASESS algorithm in QRM-MLD associated with 16QAM modulation and Turbo coding with the coding rate of 8/9 assuming a 100-MHz bandwidth for a 12-path Rayleigh fading channel (root mean square (r.m.s.) delay spread of 0.26µs and maximum Doppler frequency of 20Hz).

Mitochondrial/cell surface protein p32/gC1qR as a molecular target in tumor cells and tumor stroma  

PubMed Central

A tumor homing peptide, LyP-1, selectively binds to tumor-associated lymphatic vessels and tumor cells in certain tumors and exhibits an anti-tumor effect. Here, we show that the protein known as p32 or gC1qR is the receptor for LyP-1. Various human tumor cell lines were positive for p32 expression in culture, and the expression was increased in xenograft tumors grown from the positive cell lines. FACS analyses with anti-p32 antibodies showed that p32-positive cell lines expressed p32 at the cell surface. These cells bound and internalized LyP-1 peptide in proportion to the cell surface expression level, which correlated with malignancy rather than total p32 expression in the cells. Like the LyP-1 peptide, p32 antibodies highlighted hypoxic areas in tumors, where they bound to both tumor cells and cells that expressed macrophage/myeloid cell markers and often appeared incorporated into the walls of tumor lymphatics. Significant p32 expression was common in human cancers and the p32 levels were often greatly elevated compared to the corresponding normal tissue. These results establish p32, particularly its cell surface-expressed form, as a new marker of tumor cells and tumor-associated macrophages/myeloid cells in hypoxic/metabolically deprived areas of tumors. Its unique localization in tumors and its relative tumor specificity may make p32 a useful target in tumor diagnosis and therapy.

An engineering and economic evaluation of quick germ-quick fiber process for dry-grind ethanol facilities: analysis.  

PubMed

An engineering economic model, which is mass balanced and compositionally driven, was developed to compare the conventional corn dry-grind process and the pre-fractionation process called quick germ-quick fiber (QQ). In this model, documented in a companion article, the distillers dried grains with solubles (DDGS) price was linked with its protein and fiber content as well as with the long-term average relationship with the corn price. The detailed economic analysis showed that the QQ plant retrofitted from conventional dry-grind ethanol plant reduces the manufacturing cost of ethanol by 13.5 cent/gallon and has net present value of nearly $4 million greater than the conventional dry-grind plant at an interest rate of 4% in 15years. Ethanol and feedstock price sensitivity analysis showed that the QQ plant gains more profits when ethanol price increases than conventional dry-grind ethanol plant. An optimistic analysis of the QQ process suggests that the greater value of the modified DDGS would provide greater resistance to fluctuations in corn price for QQ facilities. This model can be used to provide decision support for ethanol producers. PMID:20207536

Evaluation of quick tests for phosphorus determination in dairy manures.  

PubMed

Nutrients in animal manure are valuable inputs in agronomic crop production. Rapid and timely information about manure nutrient content are needed to minimize the risks of phosphorus (P) over-application and losses of dissolved P (DP) in runoff from fields treated with manure. We evaluated the suitability of a commercial hand-held reflectometer, a hydrometer, and an electrical conductivity (EC) meter for determining DP and total P (TP) in dairy manures. Bulk samples (n = 107) collected from farms across CT, MD, NY, PA, and VA were highly variable in total solids (TS) concentration, ranging from 11 to 213gL(-1), in suspensions' pH (6.3-9.2), and EC (6.2-53.3 dS m(-1)). Manure DP concentrations measured using the RQFlex reflectometer (RQFlex-DP(s)) were related to molybdate-reactive P (MRP(s)) concentrations as follows: RQFlex-DP(s) = 0.471 x MRP(s) + 1102 (r2 = 0.29). Inclusion of pH and squared-pH terms improved the prediction of manure DP from RQFlex results (r2 = 0.66). Excluding five outlier samples that had pH < or = 6.9 the coefficient of determination (r2) for the MRP(s) and RQFlex-DP(s) relationship was 0.83 for 95% of the samples. Manure TS were related to hydrometer specific gravity readings (r2 = 0.53) that were in turn related to TP (r2 = 0.34), but not to either RQFlex-DP or MRP. Relationships between suspensions' EC and DP or TP were non-significant. Therefore, the RQFlex method is the only viable option for on-site quick estimates of DP that can be made more robust when complemented with TS and pH measurements. The DP quick test can provide near real-time information on soluble manure nutrient content across a wide range of handling and storage conditions on dairy farms and quick estimates of potential soluble P losses in runoff following land applications of manure.

Rapid automatic naming: easy to measure, hard to improve (quickly).  

PubMed

One explanation for the relationship between serial rapid naming (SRN) and reading is that SRN affects the temporal proximity of the phonological activation of the letters in a word, which, in turn, influences the acquisition of orthographic knowledge. To test this hypothesis, a group of Dutch first grade children was trained in the rapid serial naming of letter sounds. In addition, a no-training control group and a serial addition training group were included. Various measures of SRN and of reading were administered to evaluate the effect of the training. Before the training we found a symbol specific relationship between SRN and reading: The relationship of reading with letter-sound naming was higher than its relationship with number naming. The training of serial letter-sound naming was not successful. In contrast, the serial addition training was highly effective. We conclude that it might be difficult to quickly improve the serial rapid naming of letter sounds in beginning readers. PMID:15765004

Los Alamos National Laboratory Develops ''Quick to WIPP'' Strategy  

SciTech Connect

The Cerro Grande forest fire in May of 2000 and the terrorist events of September 11, 2001 precipitated concerns of the vulnerability of legacy contact-handled (CH), high-wattage transuranic (TRU) waste stored at Los Alamos National Laboratory (LANL). An analysis of the 9,100 cubic meters of stored CH-TRU waste revealed that 400 cubic meters or 4.5% of the inventory represented 61% of the risk. The analysis further showed that this 400 cubic meters was contained in only 2,000 drums. These facts and the question ''How can the disposition of this waste to the Waste Isolation Pilot Plant (WIPP) be accelerated?'' formed the genesis of LANL's Quick to WIPP initiative.

The distribution of quick phase interval durations in human optokinetic nystagmus.  

PubMed

There is an interesting dichotomy between models that predict the quick phase interval durations (QPIDs) of human optokinetic nystagmus (OKN). Accumulator models describe a stochastic signal in a neural network that triggers a response once the signal reaches a fixed threshold value. However, it is also possible that quick phases are triggered after eye position reaches a variable amplitude threshold. In this study, we fitted a range of probability density functions previously predicted by stochastic models of OKN (including those of the reciprocal truncated Normal, inverse Gaussian, gamma, lognormal and the mixture of two reciprocal truncated Normal distributions) to individual QPID histograms. We compared the goodness of fit between these models, and a model where the distribution of QPIDs is determined by the ratio of two correlated and truncated Normal random variables. The ratio distribution gave the best fit to the data, and we propose this is due to the approximately linear trajectory of slow phases (SPs) and that QPIDs are given by the ratio of a variable SP amplitude threshold and variable SP velocity.

DC-SIGN, C1q, and gC1qR form a trimolecular receptor complex on the surface of monocyte-derived immature dendritic cells  

PubMed Central

C1q modulates the differentiation and function of cells committed to the monocyte-derived dendritic cell (DC) lineage. Because the 2 C1q receptors found on the DC surface—gC1qR and cC1qR—lack a direct conduit into intracellular elements, we postulated that the receptors must form complexes with transmembrane partners. In the present study, we show that DC-SIGN, a C-type lectin expressed on DCs, binds directly to C1q, as assessed by ELISA, flow cytometry, and immunoprecipitation experiments. Surface plasmon resonance analysis revealed that the interaction was specific, and both intact C1q and the globular portion of C1q bound to DC-SIGN. Whereas IgG reduced this binding significantly, the Arg residues (162-163) of the C1q-A chain, which are thought to contribute to the C1q-IgG interaction, were not required for C1q binding to DC-SIGN. Binding was reduced significantly in the absence of Ca2+ and by preincubation of DC-SIGN with mannan, suggesting that C1q binds to DC-SIGN at its principal Ca2+-binding pocket, which has increased affinity for mannose residues. Antigen-capture ELISA and immunofluorescence microscopy revealed that C1q and gC1qR associate with DC-SIGN on blood DC precursors and immature DCs. The results of the present study suggest that C1q/gC1qR may regulate DC differentiation and function through the DC-SIGN–mediated induction of cell-signaling pathways.

Psychometric Properties of the Quick Inventory of Depressive Symptomatology in Adolescents  

PubMed Central

Objective The clinician-rated (QIDS-C16) and self-report (QIDS-SR16) versions of the 16-item Quick Inventory of Depressive Symptomatology have been extensively examined in adult populations. This study evaluated both versions of the QIDS and the 17-item Children’s Depressive Rating Scale-Revised (CDRS-R) in an adolescent outpatient sample. Method Both the QIDS-C16 and QIDS-SR16 were completed for the adolescents. Three different methods were used to complete the QIDS-C16: (a) adolescents’ responses to clinician interviews; (b) parents’ responses to clinician interview; and (c) a composite score using the most pathological response from the two interviews. Both classical and item response theory methods were used. Factor analyses evaluated the dimensionality of each scale. Results The sample included 140 adolescent outpatients. All versions of the QIDS, save the parent interview, and the CDRS-R were very reliable (? ? 0.8). All four versions of the QIDS are reasonably effective and unidimensional. The CDRS-R was clearly at least two-dimensional. The CDRS-R was the most discriminating among low and extremely high levels of depression. The QIDS-SR16 was the most discriminating at moderate levels of depression. There was no relation between the QIDS scores and concurrent Axis III comorbidities. Conclusion The QIDS-C16 and the QIDS-SR16 are suitable for use in adolescents.

A method for quickly and exactly extracting hepatic vein  

NASA Astrophysics Data System (ADS)

It is of vital importance that providing detailed and accurate information about hepatic vein (HV) for liver surgery planning, such as pre-operative planning of living donor liver transplantation (LDLT). Due to the different blood flow rate of intra-hepatic vascular systems and the restrictions of CT scan, it is common that HV and hepatic portal vein (HPV) are both filled with contrast medium during the scan and in high intensity in the hepatic venous phase images. As a result, the HV segmentation result obtained from the hepatic venous phase images is always contaminated by HPV which makes accurate HV modeling difficult. In this paper, we proposed a method for quick and accurate HV extraction. Based on the topological structure of intra-hepatic vessels, we analyzed the anatomical features of HV and HPV. According to the analysis, three conditions were presented to identify the nodes that connect HV with HPV in the topological structure, and thus to distinguish HV from HPV. The method costs less than one minute to extract HV and provides a correct and detailed HV model even with variations in vessels. Evaluated by two experienced radiologists, the accuracy of the HV model obtained from our method is over 97%. In the following work, we will extend our work to a comprehensive clinical evaluation and apply this method to actual LDLT surgical planning.

The occult insulinoma operative localization by quick insulin radioimmunoassay.  

PubMed

Hypoglycemia secondary to organic hyperinsulinism in children can be caused by diffuse or localized pancreatic lesions. Differentiation between these two types of lesions is of utmost importance since the surgical approach will be different. Some tumors escape detection by all preoperative investigations including ultrasound, scintiscan, arteriography, and computerized tomography. We are reporting on a 12-year-old boy with organic hyperinsulinism in whom we were unable to localize a tumor preoperatively. Peroperative determination of insulin levels from a number of sites on the pancreas enabled us to localize an insulin-producing pancreatic adenoma. This technique can be done easily by catheterizing the splenic and portal vein through a branch of the splenic vein and by serial sampling at 2 cm intervals along the portal and splenic veins. Insulin levels at these sites were determined by quick double-antibody radioimmunoassay, which allows the determination of the insulin levels within 50 minutes after sampling. There was a perfect biochemic and anatomic correlation allowing us to perform a precise distal pancreatectomy. The technique can be used to localize pancreatic adenomas and to decide how much pancreas to remove in diffuse lesions avoiding "blind" pancreatectomies. PMID:3003324

Artifacts associated with quick-freezing and freeze-drying.  

PubMed

We have studied the structures produced when nonbiological samples were subjected to quick-freezing and freeze-drying with a liquid helium cooled freeze-slamming device. Samples examined in this way included sodium chloride, sucrose, and Tris buffer. A variety of filamentlike and trabeculumlike structures were formed in these preparations. These structures may represent eutectic mixtures formed during the growth of small ice crystals during the freezing process, and exposed during the rapid sublimation of pure ice during the etching process. Samples of biological membranes (isolated chloroplast membranes) were prepared in various buffers by means of this technique. In distilled water, excellent replicas of membrane surfaces were obtained. In salt solutions, however, the membranes appeared to be embedded in a network of thin filaments appearing very much like a cytoskeletal lattice. It is concluded that extreme caution must be used when employing this preparation technique for studies of cell architecture, and that extensive washing of cell components in distilled water may be necessary to obtain faithful representations of cell structure.

Quick monitoring of pozzolanic reactivity of waste ashes.  

PubMed

This article proposes a quick method of monitoring for pozzolanic reactivity of waste ashes by investigating the electrical conductivity of the suspension at an elevated temperature. This suspension is obtained by mixing tested pozzolan with an ordinary Portland cement (OPC) solution produced by mixing ordinary Portland cement with water. For comparison, silica fume, metakaolin, rice husk ash and river sand - whose pozzolanic reactivities range from reactive to inert - were used in the experimental investigation. The electrical conductivity of the suspension was continually recorded by using an electrical conductivity meter and stored by using a personal computer for a period of slightly over 1day. The indicative parameters that can be related to pozzolanic reactivity were discussed and analyzed in detail. It was found that it is possible to determine the pozzolanic reactivity of fly ash within 28h by using the proposed technique, as compared to 7 or 28 days for the determination of strength activity index according to ASTM. This technique would help concrete technologists to speedily investigate the quality of fly ash for use as a cement replacement in order to alleviate pollution caused by cement production and solve disposal problems of waste ashes.

The quick motor function test: a new tool to rate clinical severity and motor function in Pompe patients.  

PubMed

Pompe disease is a lysosomal storage disorder characterized by progressive muscle weakness. With the emergence of new treatment options, psychometrically robust outcome measures are needed to monitor patients' clinical status. We constructed a motor function test that is easy and quick to use. The Quick Motor Function Test (QMFT) was constructed on the basis of the clinical expertise of several physicians involved in the care of Pompe patients; the Gross Motor Function Measure and the IPA/Erasmus MC Pompe survey. The test comprises 16 items. Validity and test reliability were determined in a cohort of 91 Pompe patients (5 to 76 years of age). In addition, responsiveness of the scale to changes in clinical condition over time was examined in a subgroup of 18 patients receiving treatment and 23 untreated patients. Interrater and intrarater reliabilities were good (intraclass correlation coefficients: 0.78 to 0.98 and 0.76 to 0.98). The test correlated strongly with proximal muscle strength assessed by hand held dynamometry and manual muscle testing (rs= 0.81, rs=0.89), and showed significant differences between patient groups with different disease severities. A clinical-empirical exploration to assess responsiveness showed promising results, albeit it should be repeated in a larger group of patients. In conclusion, the Quick Motor Function Test can reliably rate clinical severity and motor function in children and adults with Pompe disease. PMID:21912959

A method for quick assessment of CO2 storage capacity in closedand semi-closed saline formations  

SciTech Connect

Saline aquifers of high permeability bounded by overlying/underlying seals may be surrounded laterally by low-permeability zones, possibly caused by natural heterogeneity and/or faulting. Carbon dioxide (CO{sub 2}) injection into and storage in such 'closed' systems with impervious seals, or 'semi-closed' systems with nonideal (low-permeability) seals, is different from that in 'open' systems, from which the displaced brine can easily escape laterally. In closed or semi-closed systems, the pressure buildup caused by continuous industrial-scale CO{sub 2} injection may have a limiting effect on CO{sub 2} storage capacity, because geomechanical damage caused by overpressure needs to be avoided. In this research, a simple analytical method was developed for the quick assessment of the CO{sub 2} storage capacity in such closed and semi-closed systems. This quick-assessment method is based on the fact that native brine (of an equivalent volume) displaced by the cumulative injected CO{sub 2} occupies additional pore volume within the storage formation and the seals, provided by pore and brine compressibility in response to pressure buildup. With nonideal seals, brine may also leak through the seals into overlying/underlying formations. The quick-assessment method calculates these brine displacement contributions in response to an estimated average pressure buildup in the storage reservoir. The CO{sub 2} storage capacity and the transient domain-averaged pressure buildup estimated through the quick-assessment method were compared with the 'true' values obtained using detailed numerical simulations of CO{sub 2} and brine transport in a two-dimensional radial system. The good agreement indicates that the proposed method can produce reasonable approximations for storage-formation-seal systems of various geometric and hydrogeological properties.

Quick identification of acute chest pain patients study (QICS)  

PubMed Central

Background Patients with acute chest pain are often referred to the emergency ward and extensively investigated. Investigations are costly and could induce unnecessary complications, especially with invasive diagnostics. Nevertheless, chest pain patients have high mortalities. Fast identification of high-risk patients is crucial. Therefore several strategies have been developed including specific symptoms, signs, laboratory measurements, and imaging. Methods/Design The Quick Identification of acute Chest pain Study (QICS) will investigate whether a combined use of specific symptoms and signs, electrocardiography, routine and new laboratory measures, adjunctive imaging including electron beam (EBT) computed tomography (CT) and contrast multislice CT (MSCT) will have a high diagnostic yield for patients with acute chest pain. All patients will be investigated according a standardized protocol in the Emergency Department. Serum and plasma will be frozen for future analysis for a wide range of biomarkers at a later time point. The primary endpoint is the safe recognition of low-risk chest pain patients directly at presentation. Secondary endpoint is the identification of a wide range of sensitive predictive clinical markers, chemical biomarkers and radiological markers in acute chest pain patients. Chemical biomarkers will be compared to quantitative CT measurements of coronary atherosclerosis as a surrogate endpoint. Chemical biomarkers will also be compared in head to head comparison and for their additional value. Discussion This will be a very extensive investigation of a wide range of risk predictors in acute chest pain patients. New reliable fast and cheap diagnostic algorithm resulting from the test results might improve chest pain patients' prognosis, and reduce unnecessary costs and diagnostic complications.

Hayabusa Reentry and Recovery of Its Capsule -Quick Report  

NASA Astrophysics Data System (ADS)

The Hayabusa spacecraft successfully returned to the Earth and re-entered into the atmosphere for sample recovery after also the successful touching-downs to NEO Itokawa in 2005. The reentry occurred on June 13th, and took place in Woomera Prohibited Area (WPA) of Australia. This paper presents how the reentry and recovery operations were performed, and also reports the current status about the sample curation activity. The Hayabusa mission aims at demonstrating key technologies requisite for future real Sample and Return missions. However, the spacecraft adopted the actual Sample and Return flight sequence and was designed to make a world's first round trip to an extra terrestrial object with touching-down and lifting-off. It is the spacecraft propelled by the ion engines aboard for interplanetary cruise. The Hayabusa spacecraft launched in May of 2003 reached NEO Itokawa in September of 2005 via Earth gravity assist in May of 2004. It stayed there for about two and a half months, and performed detailed scientific observation and mapping and determination of the shape. In November of 2005, the spacecraft made two touching-downs and lifting-offs having attempted collection of surface sample. At the second opportunity, the spacecraft directed shooting a projectile. But, due to the programming problem, presumably the projectile was not shot. However, the spacecraft may have captured some small amount of sample particles in a catcher aboard, when the spacecraft made actual touches down to the surface. The spacecraft suffered from fuel leak in December of 2005, and the communication resumed after seven weeks of hiatus. And the ion engines all faced their life by November of 2009, and the project team devised an alternative drive configuration and successfully coped with the difficulty. Despite many hardships, the spacecraft has been operated for return cruise, and it made a reentry for sample recovery this June. The sample catcher was retrieved at WPA and transported back to the curation facility of JAXA. Currently the curators have examined analyzed the catcher recovered. This presentation quickly reports recent status of the spacecraft, capsule and sample analysis.

Topside ionosphere and plasmasphere: Use of NeQuick in connection with Gallagher plasmasphere model  

NASA Astrophysics Data System (ADS)

The NeQuick ionospheric electron density model has a very simple topside formulation, which allows taking into account the electron content up to 20,000 km. In the present work, the Gallagher model has been used in connection with NeQuick to provide a more realistic representation of the electron concentration distribution in the plasmasphere. An analysis of the impact of the proposed modification in low geomagnetic latitudes (±40°) on modeled vertical total electron content has been performed for different levels of solar activity, season, and universal time. In addition, GPS vertical total electron content values obtained from seven IGS (International GPS Service) station data have been compared with the NeQuick and NeQuick+Gallagher vertical total electron content values, confirming the importance of including a plasmaspheric formulation in the NeQuick model.

Distal radius fractures: a prospective randomized comparison of fibreglass tape with QuickCast.  

PubMed

Cast immobilization remains the most commonly employed method in the treatment of distal radius fractures. In an effort to test a new shrinkable polymer-coated casting material (QuickCast), a prospective randomized study was performed on 30 consecutive distal radius fractures. Fractures were divided into three groups based on the severity of fracture and treated with either a conventional short-arm fibreglass tape cast or a QuickCast. Results showed no significant differences in minor cast complications or maintenance of fracture reduction between conventional fibreglass tape and the QuickCast material. The shrinkable QuickCast, however, resulted in an average of one less cast change in all groups. This reduction in time and labour must be weighed against the slightly increased cost of the QuickCast immobilizer. PMID:9282188

Foraging strategy quick response to temperature of Messor barbarus (Hymenoptera: Formicidae) in Mediterranean environments.  

PubMed

Animals principally forage to try to maximize energy intake per unit of feeding time, developing different foraging strategies. Temperature effects on foraging have been observed in diverse ant species; these effects are limited to the duration of foraging or the number of foragers involved. The harvester ant Messor barbarus L. 1767 has a specialized foraging strategy that consists in the formation of worker trails. Because of the high permeability of their body integument, we presume that the length, shape, and type of foraging trails of M. barbarus must be affected by temperature conditions. From mid-June to mid-August 1999, we tested the effect on these trail characteristics in a Mediterranean forest. We found that thermal stress force ants to use a foraging pattern based on the variation of the workers trail structure. Ants exploit earlier well-known sources using long physical trails, but as temperatures increases throughout the morning, foragers reduce the length of the foraging column gradually, looking for alternative food sources in nonphysical trails. This study shows that animal forage can be highly adaptable and versatile in environments with high daily variations. PMID:18801249

NASA Astrophysics Data System (ADS)

An assessment of implementing an oscillation free FRAM algorithm on the flow-oriented skew upwind and QUICK schemes is made in this study for convection dominated flow problem. The monotonically bounded FARM method, along with the attractive properties of flow-oriented QUICK and skew upwind schemes, can capture the nearly discontinuous phenomena in the flow field. The candidates of QUICK-family include original QUICK, QUICK for two dimensions (QUICK-2D), and QUICK with Estimated Streaming Terms (QUICKEST). The candidates in skew family include Skew Upwind Differencing (SUD), Skew Upwind Differencing with artificial Cutoff (SUD-Cut), Volume-Weighted Skew Upwind Differencing (VWSUD), Corner Skew Upwind Differencing (CSUD), and Directional Transportive Upwind Differencing (DTUD) schemes. The performance of filtering methodology on the investigated schemes is evaluated by testing the following three problems: (1) Pure convection of an obilque-step profile, (2) Transport of a cosine hill or rectangular block in a rotating flowfield, (3) Backward-facing step and driven cavity problems. The best schemes among the investigated two families are QUICKEST and DTUD respectively.

Development of a Quick Look Pandemic Influenza Modeling and Visualization Tool  

SciTech Connect

Federal, State, and local decision makers and public health officials must prepare and exercise complex plans to contend with a variety of possible mass casualty events, such as pandemic influenza. Through the provision of quick look tools (QLTs) focused on mass casualty events, such planning can be done with higher accuracy and more realism through the combination of interactive simulation and visualization in these tools. If an event happens, the QLTs can then be employed to rapidly assess and execute alternative mitigation strategies, and thereby minimize casualties. This can be achieved by conducting numerous 'what-if' assessments prior to any event in order to assess potential health impacts (e.g., number of sick individuals), required community resources (e.g., vaccinations and hospital beds), and optimal mitigative decision strategies (e.g., school closures) during the course of a pandemic. In this presentation, we overview and demonstrate a pandemic influenza QLT, discuss some of the modeling methods and construct and visual analytic components and interface, and outline additional development concepts. These include the incorporation of a user selectable infectious disease palette, simultaneous visualization of decision alternatives, additional resource elements associated with emergency response (e.g., first responders and medical professionals), and provisions for other potential disaster events.

Anticipatory synergy adjustments: preparing a quick action in an unknown direction.  

PubMed

We studied a mechanism of feed-forward control of a multi-finger action, namely anticipatory synergy adjustments (ASAs), prior to a quick force correction in response to a change in the gain of the visual feedback. Synergies were defined as co-varied across trials adjustments of commands to fingers that stabilized (decreased variance of) the total force. We hypothesized that ASAs would be highly sensitive to prior information about the timing of the action but not to information on its direction, i.e., on whether the gain would go up or down. The subjects produced accurate constant total force by pressing with four fingers on individual force sensors. The feedback signal could change from veridical (the sum of finger forces) to modified, with the middle finger force multiplied by 0.2 or by 1.8. The timing of the gain change and its direction could be known or unknown to the subject in advance. When the timing of the gain change was known, ASA was seen as a drop in the synergy index starting about 250-300 ms prior to the first visible correction of the total force. When the gain change timing was unknown, ASAs started much later, less than 100 ms prior to the total force correction. The magnitude of synergy index changes was significantly larger under the "time known" conditions. Information on the direction of the visual gain change had no effect on the ASA timing, while the ASA magnitude was somewhat larger when this information was not available to the subject. After the total force correction, the synergy index was significantly larger for the force signal computed using the modified gain values as compared to the synergy index value for the actual total force. We conclude that ASAs represent an important feed-forward motor control mechanism that allows preparing for a quick action even when the direction of the action is not known in advance. The results emphasize the subtle control of multi-finger synergies that are specific to the exact contributions of individual fingers to performance variables. The data fit well the central back-coupling hypothesis of synergies and the idea of control with referent body configurations. PMID:23494385

Delineation of a quick clay zone at Smørgrav, Norway, with electromagnetic methods under geotechnical constraints  

NASA Astrophysics Data System (ADS)

In many coastal areas of North America and Scandinavia, post-glacial clay sediments have emerged above sea level due to iso-static uplift. These clays are often destabilised by fresh water leaching and transformed to so-called quick clays as at the investigated area at Smørgrav, Norway. Slight mechanical disturbances of these materials may trigger landslides. Since the leaching increases the electrical resistivity of quick clay as compared to normal marine clay, the application of electromagnetic (EM) methods is of particular interest in the study of quick clay structures.

Quick blots and nonradioactive detection of DNA probes for the identification of mosquitoes.  

PubMed

The quick blot protocol is an improved technique for preparing crude insect homogenates for hybridization to nucleic acid probes. Individual insects are ground in wells of a microtiter plate and transferred to a dot blot manifold. This allows preparation of multiple filters and provides uniformity and an orderly arrangement of samples. The high background detection resulting from use of crude insect homogenates with nonradioactive detection systems was eliminated by incubating quick blot filters in a laundry stain remover containing proteases. We used mosquito species-specific DNA probes to demonstrate the effectiveness of nonradioactive DNA labeling systems with quick blots. PMID:1357085

Build great web search applications quickly with Solr and Blacklight  

NASA Astrophysics Data System (ADS)

The NRAO faced performance and usability issues after releasing a single-search-box ("Google-like") web application to query data across all NRAO telescope archives. Running queries with several relations across multiple databases proved to be very expensive in compute resources. An investigation for a better platform led to Solr and Blacklight, a solution stack which allows in-house development to focus on in-house problems. Solr is an Apache project built on Lucene to provide a modern search server with a rich set of features and impressive performance. Blacklight is a web user interface (UI) for Solr primarily developed by libraries at the University of Virginia and Stanford University. Though Blacklight targets libraries, it is highly adaptable for many types of search applications which benefit from the faceted searching and browsing, minimal configuration, and flexible query parsing of Solr and Lucene. The result: one highly reused codebase provides for millisecond response times and a flexible UI. Not just for observational data, NRAO is rolling out Solr and Blacklight across domains of library databases, telescope proposals, and more -- in addition to telescope data products, where integration with the Virtual Observatory is on-going.

A sensitivity comparison of the Quick and Owren prothrombin time methods in oral anticoagulant therapy  

PubMed Central

Prothrombin time (PT) is the leading test for monitoring oral anticoagulation therapy (OAT). According to the World Health Organization recommendation, International Normalized Ratio (INR) results obtained from the same patient samples with the major PT methods (Quick and Owren) should be the same when the therapeutic range is the same. In our study blood samples were obtained from 207 OAT patients. We analyzed the samples using two Quick and two Owren PT (combined thromboplastin) reagents for INR and assessed the sensitivity and true coagulation activity using a new-generation PT method. The INR values with the Quick PT and Owren PT methods were very similar around the normal range, while unacceptable differences were seen within the therapeutic range and at higher INR values. The Quick PT results as INR are clearly lower than those given by Owren PT and the difference increases toward higher INR. The new PT method functions well with both Owren PT reagents, and we can calculate the true active INR. The Quick PT methods show no sensitivity to coagulation inhibition measurement. The harmonization of the INR is an important goal for the safety of OAT patients. More accurate INR results reduce morbidity and mortality, and the therapeutic ranges should be similar worldwide. In this study we found unacceptable differences in INR results produced by the two PT methods. The new method showed a lack of sensitivity to Quick PT. For the global harmonization of OAT therapy and for INR accuracy only the more sensitive Owren PT method should be used.

Correction of B2bot for NeQuick During Low Solar Activity at Hainan Station  

NASA Astrophysics Data System (ADS)

NeQuick ionospheric electron density model, which has been developed to version 2, produces the full electron density profile in the ionosphere. using Epstein layer formalism, Each part of the profile is modeled. Simple empirical relations are used to compute the thicknesses of each layer. In this paper, using the data during low solar activity at Hainan, China (109.1E, 19.5N; Geomagnetic coordinates178.95E, 8.1N), measured with DPS-4, we study the diurnal and seasonal variations of B2bot, B2(B2best-B2NeQuick2) and R(B2best/B2NeQuick2) at that region. The results show that (1) During day-time in this region the value of B2bot is under-estimated in all seasons (about 30km in equinox, 40km in summer and 20km in winter). (2) The differences between B2best and B2NeQuick2 have diurnal and seasonal variations. (3) It is possible to improve the B2bot parameter of the NeQuick model at that region during low solar activity. Based on the research in the above, we use a coefficient R with LT in different seasons to correct the B2bot formula of NeQuick. The results of correction show that (1) Using the formula, the B2bot of NeQuick is improved. The maximum standard deviation of new formula is less than 22.6451km, and that of old is less than 63.6301km. (2) Effect of correction in equinox and winter is better than that in summer. (3) Effect of correction during night-time is better than that during day-time.

Quick-MESS: A Fast Statistical Tool for Exoplanet Imaging Surveys  

NASA Astrophysics Data System (ADS)

Several tools have been developed in the past few years for the statistical analysis of the exoplanet search surveys, mostly using a combination of Monte Carlo simulations or a Bayesian approach. Here we present Quick-MESS, a grid-based, non-Monte Carlo tool aimed to perform statistical analyses on results from direct imaging surveys, as well as help with the planning of these surveys. Quick-MESS uses the (expected) contrast curves for direct imaging surveys to assess for each target the probability that a planet of a given mass and semimajor axis can be detected. By using a grid-based approach, Quick-MESS is typically more than an order of magnitude faster than tools based on Monte Carlo sampling of the planet distribution. In addition, Quick-MESS is extremely flexible, enabling the study of a large range of parameter space for the mass and semimajor axes distributions without the need of resimulating the planet distribution. In order to show examples of the capabilities of Quick-MESS, we present the analysis of the Gemini Deep Planet Survey and the predictions for upcoming surveys with extreme-AO instruments.

QuickSite{sup SM}, the Argonne expedited site characterization methodology,  

SciTech Connect

Expedited site characterization (ESC), developed by Argonne National Laboratory, is an interactive, integrated process emphasizing the use of existing data of sufficient quality, multiple complementary characterization methods, and on-site decision making to optimize site investigations. The Argonne ESC is the basis for the provisional ESC standard of the ASTM (American Society for Testing and Materials). QuickSite{sup SM} is the implementation package developed by Argonne to facilitate ESC of sites contaminated with hazardous wastes. At various sites, Argonne has successfully implemented QuickSite{sup SM} and demonstrated the technical superiority of the ESC process over traditional methodologies guided by statistics and random-sampling approaches. For example, in a QuickSite{sup SM} characterization of a perched aquifer at the Pantex Plant in Texas, past data and geochemical analyses of existing wells were used to develop a model for recharge and contaminant movement. With the model as a guide, closure was achieved with minimal field work.

Correct implementation of the Argonne QuickSite{sup SM} process for preremedial site investigations  

SciTech Connect

Expedited site characterization (ESC), developed by Argonne National Laboratory, is an interactive, integrated process emphasizing the use of existing data of sufficient quality, multiple complementary characterization methods, and on-site decision making to optimize environmental site investigations. The Argonne ESC is the basis for the provisional ESC standard guide of the ASTM (American Society for Testing and Materials). QuickSite{sup SM} is the implementation package developed by Argonne to facilitate ESC of sites contaminated with hazardous wastes. At various sites, Argonne has successfully implemented QuickSite{sup SM} and demonstrated the technical superiority of the ESC process over traditional methodologies guided by statistics and random-sampling approaches. A key feature in the success of QuickSite{sup SM} investigations is achieving an understanding of the subsurface geologic and hydrogeologic controls and processes at a site before extensive sampling efforts begin. The QuickSite{sup SM} investigation at the Tustin Marine Corps Air Station (MCAS) in California will be used to illustrate the importance of understanding these potential controls in minimizing sampling activities and correctly predicting potential contaminant migration patterns for risk assessment.

The Gene Ontology (GO) has proven to be a valuable resource for functional annotation of gene products. At well over 27 000 terms, the descriptiveness of GO has increased rapidly in line with the biological data it represents. Therefore, it is vital to be able to easily and quickly mine the functional information that has been made available through these GO terms being associated with gene products. QuickGO is a fast, web-based tool for browsing the GO and all associated GO annotations provided by the GOA group. After undergoing a redevelopment, QuickGO is now able to offer many more features beyond simple browsing. Users have responded well to the new tool and given very positive feedback about its usefulness. This tutorial will demonstrate how some of these features could be useful to the researcher wanting to discover more about their dataset, particular areas of biology or to find new ways of directing their research.

A novel algorithm for quick and continuous tracing the change of radon concentration in environment  

NASA Astrophysics Data System (ADS)

Several measurements of the radon concentration are performed by RAD7 in the University of South China. We find that 30-40 min is needed for RAD7 for tracing the concentration of the standard radon chamber. There are two reasons. The first is that the sufficient time of air cycle is needed for the radon concentration in internal cell of RAD7 equal to that of the environment; and the second is that the sufficient decay time is needed for the 218Po concentration in internal cell of RAD7 equal to that of the radon. We used a zeroth order approximation to describe the evolution of the environment radon concentration, and obtained a novel algorithm for quick and continuous tracing the change of radon concentration. The corrected radon concentration obtained through this method is in good agreement with the reference value. This method can be applied to develop and improve the instruments for tracing the change of radon concentration quickly.

Rapidly Measuring the Speed of Unconscious Learning: Amnesics Learn Quickly and Happy People Slowly  

PubMed Central

Background We introduce a method for quickly determining the rate of implicit learning. Methodology/Principal Findings The task involves making a binary prediction for a probabilistic sequence over 10 minutes; from this it is possible to determine the influence of events of a different number of trials in the past on the current decision. This profile directly reflects the learning rate parameter of a large class of learning algorithms including the delta and Rescorla-Wagner rules. To illustrate the use of the method, we compare a person with amnesia with normal controls and we compare people with induced happy and sad moods. Conclusions/Significance Learning on the task is likely both associative and implicit. We argue theoretically and demonstrate empirically that both amnesia and also transient negative moods can be associated with an especially large learning rate: People with amnesia can learn quickly and happy people slowly.

Web services interface for Space Weather: NeQuick 2 web and experimental TEC Calibration  

NASA Astrophysics Data System (ADS)

A web front-end has been recently developed and released to allow retrieving and plotting ionospheric parameters computed by the latest version of the model, NeQuick 2. NeQuick is a quick-run ionospheric electron density model particularly designed for trans-ionospheric propagation applications. It has been developed at the Aeronomy and Radiopropagation Laboratory (now T/ICT4D Laboratory) of the Abdus Salam International Centre for Theoretical Physics (ICTP) - Trieste, Italy with the collaboration of the Institute for Geophysics, Astrophysics and Meteorology (IGAM) of the University of Graz, Austria. To describe the electron density of the ionosphere up to the peak of the F2 layer, NeQuick uses a profile formulation which includes five semi-Epstein layers with modelled thickness parameters. Through a simple web interface users can exploit all the model features including the possibility of computing the electron density and visualizing the corresponding Total Electron Content (TEC) along any ground-to-satellite straight line ray-path. Indeed, the TEC is the ionospheric parameter retrieved from the GPS measurements. It complements the experimental data obtained with diverse kinds of sensors and can be considered a major source of ionospheric information. Since the TEC is not a direct measurement, a "de-biasing" procedure or calibration has to be applied to obtain the relevant values from the raw GPS observables. Using the observation and navigation RINEX files corresponding to a single receiver as input data, the web application allows the user to compute the slant and/or vertical TEC following the concept of the "arc-by-arc" offsets estimation. The combined use of both tools, freely available from the T/ICT4D Web site, will allow the comparison of experimentally derived slant and vertical TEC with modelled values. An online demonstration of the capabilities of the mentioned web services will be illustrated.

Molecular Evolution of Slow and Quick Anion Channels (SLACs and QUACs/ALMTs)  

PubMed Central

Electrophysiological analyses conducted about 25?years ago detected two types of anion channels in the plasma membrane of guard cells. One type of channel responds slowly to changes in membrane voltage while the other responds quickly. Consequently, they were named SLAC, for SLow Anion Channel, and QUAC, for QUick Anion Channel. Recently, genes SLAC1 and QUAC1/ALMT12, underlying the two different anion current components, could be identified in the model plant Arabidopsis thaliana. Expression of the gene products in Xenopus oocytes confirmed the quick and slow current kinetics. In this study we provide an overview on our current knowledge on slow and quick anion channels in plants and analyze the molecular evolution of ALMT/QUAC-like and SLAC-like channels. We discovered fingerprints that allow screening databases for these channel types and were able to identify 192 (177 non-redundant) SLAC-like and 422 (402 non-redundant) ALMT/QUAC-like proteins in the fully sequenced genomes of 32 plant species. Phylogenetic analyses provided new insights into the molecular evolution of these channel types. We also combined sequence alignment and clustering with predictions of protein features, leading to the identification of known conserved phosphorylation sites in SLAC1-like channels along with potential sites that have not been yet experimentally confirmed. Using a similar strategy to analyze the hydropathicity of ALMT/QUAC-like channels, we propose a modified topology with additional transmembrane regions that integrates structure and function of these membrane proteins. Our results suggest that cross-referencing phylogenetic analyses with position-specific protein properties and functional data could be a very powerful tool for genome research approaches in general.

Relationships between versional and vergent quick phases of the involuntary version-vergence nystagmus  

PubMed Central

We used ground-plane motion stimuli displayed on a computer monitor positioned below eye level to induce involuntary version-vergence nystagmus (VVN). The VVN was recorded with a search coil system. It was shown that the VVN had both vertical versional and horizontal vergence components. The VVN induced by backward motion (toward subjects) had upward versional and divergence quick phases, whereas those induced by forward motion (away from subjects) had downward and biphasic divergence-convergence quick phases. The versional and vergence components of the VVN quick phases were analyzed. A temporal dissociation of about 20 ms between version velocity peak and convergence velocity peak was revealed, which supported a modified saccade-related vergence burst neuron (SVBN) model. We suggest that the temporal dissociation may be partly because of a lower-level OKN control mechanism. Vergence peak time was dependent on version peak time. Linear relationships between vergence peak velocity and versional saccadic peak velocity were demonstrated, which was in line with the new multiplicative model. Our data support the hypothesis that the vergence system and the saccadic system can act separately, but interact with each other whenever their movements occur simultaneously.

Systolic quick releases of nonexcised blood-perfused canine papillary muscle.  

PubMed

Systolic stiffness was studied in five coronary perfused twitching papillary muscles of canine right ventricles. The muscles beat at regular sinus rhythms at 37 degrees C. They were shortened quickly at about 10 muscle lengths/s in the middle of isometric contractions. Systolic force decreased exponentially with the shortening in the force-length diagram. Relating Lagrangian stress (sigma) and strain change (delta epsilon) relative to isometric length calculated from the force-length relationship curve during quick release, I found a linear relationship between ln sigma and delta epsilon. This indicates that the systolic stres-strain relationship of the canine papillary muscle can be approximated by an exponential curve, sigma = sigma m exp(k . delta epsilon), where sigma m = isometric stress at the onset of quick release. The mean +/- SE of the stiffness constant k was calculated to be 55 +/- 8 (dimensionless). These k values are greater than those of excised cat papillary muscles at 37 degrees C reported in literature. This difference in k values may be ascribed to the difference in the mechanical property of the uncut pinned end of the present preparation as opposed to the cut clamped end of the conventional preparation, although the canine and feline papillary muscles may simply have the different k values.

Populations and activities of nitrifier can be significantly influenced by air-drying. A 35-day incubation study was conducted to determine the effects of air-drying on nitrification potential of four acid subtropical soils after applying 0 and 150 mg x kg(-1) of ammonium bicarbonate. Four soils, designated QR, QU, SR and SU, derived from Quaternary red earth and Tertiary red sandstone, were collected from rice and upland field. The results indicated that, without ammonium input, the responses of nitrification in upland soils to air-drying were insignificant (p > 0.05). The nitrification ratio in fresh and air-dried samples of soil QU were 48% and 54% respectively, and 76% and 78% for SU; however, air-drying did have a significant effect on the nitrification in paddy soils (p < 0.01). Nitrification ratios were 40% and 89% for fresh and air-dried samples of QR, 76% and 94% for SR, and there was a lag-phase of the nitrification in air-dried paddy soils. Ammonium input would accelerate nitrification and make the nitrification ratios of fresh samples significantly higher than those of air-dried ones. In generally, land-use type presents a significant impact on the response of nitrification to air-drying effect, and there was a significant interaction of land-use type and fertilization.

QuickBird derived vegetation parameters for soil erosion risk assessment in an alpine catchment  

NASA Astrophysics Data System (ADS)

The focus of soil erosion research in the Alps has been in two categories: (i) on-site measurements which are rather small scale point measurements on selected plots often constrained to irrigation experiments or (ii) off-site quantification of sediment delivery at the outlet of the catchment. Results of both categories showed that an intact vegetation cover prevents soil loss. With the recent availability of high-resolution satellites such as IKONOS and QuickBird options for detecting and monitoring of vegetation parameters have increased. The aim of this study is to evaluate the usefulness of QuickBird derived vegetation parameters in soil erosion models by comparison to Cesium-137 (Cs-137) soil erosion estimates. The study site (67km2) is located in the Central Swiss Alps and is dominated by grasslands with strong anthropogenic influences due to farming for centuries. Linear spectral unmixing and supervised classification is applied to produce maps of fractional vegetation cover (FVC) for grasslands and detailed land-cover maps from QuickBird imagery. The maps are used to adapt the C factor, which accounts for land management in the Universal Soil Loss Equation (USLE). Further the data was introduced to the Pan-European Soil Erosion Risk Assessment (PESERA) model. Supervised land-cover classification yielded a total accuracy of 93.3%. Linear spectral unmixing of vegetation abundance showed a significant (at the 0.01 level) correlation to ground truth FVC. Both models yielded higher absolute soil erosion estimates and an improvement of spatial patterns when FVC and a detailed land-cover maps are considered. However, discrepancies between model estimates and Cs-137 erosion estimates remained, especially for the PESERA model. This is leading to the assumption that soil erosion processes not considered in the models, e.g. soil erosion caused by snow gliding, play a decisive role.

Validation of B2 bot in the NeQuick model during high solar activity at Hainan station  

NASA Astrophysics Data System (ADS)

NeQuick ionospheric electron density model, which has been developed to version 2, produces the full electron density profile in the ionosphere. Each part of the profile is modeled using Epstein layer formalism. Simple empirical relations are used to compute the thicknesses of each layer. In order to validate the B2 bot parameter in the NeQuick model during high solar activity, we use the data at Hainan, China (109.1°E, 19.5°N; Geomagnetic coordinates: 178.95°E, 8.1°N), measured with DPS-4, and study the diurnal and seasonal variations of B2 bot, ?B2 (B2 best - B2 NeQuick 2 ) and the seasonal median values of B2 best/B2 NeQuick 2 at that region. The results show that, (1) The differences between B2 best and B2 NeQuick 2 have diurnal and seasonal variations. (2) The diurnal variations of B2 NeQuick 2 are smaller than those of B2 best. (3) Generally, except for early morning the experimental values are properly reproduced. (4) Generally, during morning the NeQuick model has an underestimation. The magnitude of underestimation varies with LT and season.

HARD REAL TIME QUICK EXAFS DATA ACQUISITION WITH ALL OPEN SOURCE SOFTWARE ON A COMMODITY PERSONAL COMPUTER.  

SciTech Connect

We describe here the data acquisition subsystem of the Quick EXAFS (QEXAFS) experiment at the National Synchrotron Light Source of Brookhaven National Laboratory. For ease of future growth and flexibility, almost all software components are open source with very active maintainers. Among them, Linux running on x86 desktop computer, RTAI for real-time response, COMEDI driver for the data acquisition hardware, Qt and PyQt for graphical user interface, PyQwt for plotting, and Python for scripting. The signal (A/D) and energy-reading (IK220 encoder) devices in the PCI computer are also EPICS enabled. The control system scans the monochromator energy through a networked EPICS motor. With the real-time kernel, the system is capable of deterministic data-sampling period of tens of micro-seconds with typical timing-jitter of several micro-seconds. At the same time, Linux is running in other non-real-time processes handling the user-interface. A modern Qt-based controls-front end enhances productivity. The fast plotting and zooming of data in time or energy coordinates let the experimenters verify the quality of the data before detailed analysis. Python scripting is built-in for automation. The typical data-rate for continuous runs are around ten mega-bytes per minute.

Evidence for Subtle Verbal Fluency Deficits in Occasional Stimulant Users: Quick to Play Loose with Verbal Rules  

PubMed Central

Psychostimulants like cocaine and amphetamine are commonly abused by young adults who often state that they take these drugs to increase social or cognitive performance. The current study tested the hypothesis that individuals at early stages of occasional stimulant use show subtle executive dysfunctions such as verbal fluency deficits. 155 young (age 18-25), non-dependent occasional users of stimulants and 49 stimulant naïve comparison subjects performed the Delis-Kaplan Verbal Fluency test. Correlation and median split analyses were conducted to account for stimulant history and co-drug use. Compared to stimulant naïve subjects, occasional stimulant users generated significantly more responses on an over-learned verbal fluency task (Category Fluency), but at the expense of increased error rates (Set Loss and Repetition Errors). These performance differences were not related to lifetime uses of stimulants or marijuana. Taken together, these results support the hypothesis that individuals who are using stimulants occasionally exhibit subtle executive dysfunctions when required to generate verbal sets under time pressure. In particular, occasional stimulant users apply quickly but inaccurately verbal rules, which may represent a mix of diminished cognitive flexibility along with increased rigidity and impulsivity. This specific executive dysfunction may help to identify individuals at risk for stimulant use or dependence.

Three-dimensional laser wakefield acceleration (LWFA) simulations have recently been performed to benchmark the commonly used particle-in-cell (PIC) codes VORPAL, OSIRIS, and QuickPIC. The simulations were run in parallel on over 100 processors, using parameters relevant to LWFA with ultra-short Ti-Sapphire laser pulses propagating in hydrogen gas. Both first-order and second-order particle shapes were employed. We present the results of this benchmarking exercise, and show that accelerating gradients from full PIC agree for all values of a{sub 0} and that full and reduced PIC agree well for values of a{sub 0} approaching 4.

Multilevel spatial semantic model for urban house information extraction automatically from QuickBird imagery  

NASA Astrophysics Data System (ADS)

Based on the introduction to the characters and constructing flow of space semantic model, the feature space and context of house information in high resolution remote sensing image are analyzed, and the house semantic network model of Quick Bird image is also constructed. Furthermore, the accuracy and practicability of space semantic model are checked up through extracting house information automatically from Quick Bird image after extracting candidate semantic nodes to the image by taking advantage of grey division method, window threshold value method and Hough transformation. Sample result indicates that its type coherence, shape coherence and area coherence are 96.75%, 89.5 % and 88 % respectively. Thereinto the effect of the extraction of the houses with rectangular roof is the best and that with herringbone and the polygonal roofs is just ideal. However, the effect of the extraction of the houses with round roof is not satisfied and thus they need the further perfection to the semantic model to make them own higher applied value.

Supply curve impacts of Quick Start projects in Phase 1 of the Resource Supply Expansion Program  

SciTech Connect

The Pacific Northwest Laboratory (PNL) prepared this report under contract to the Bonneville Power Administration (Bonneville), as part of the Resource Supply Expansion Project (RSEP). RSEP is a regional program instituted by Bonneville to expand conservation and renewable generation options available to resource planners and utilities. Resource alternatives are increased by RSEP through demonstration projects designed in a collaborative process that targets specific barriers to resource development including institutional, market, and reliability barriers. RSEP was launched with several projects that were designed and implemented quickly in 1992 to lay a foundation for future collaboration. The purpose of this report is to introduce the goal and structure of RSEP and to describe the so-called ``Quick Start`` RSEP projects in Phase One of RSEP. This description includes a preliminary estimate of the energy savings and/or other expected impacts of RSEP projects funded in FY 1992 and 1993. Similar estimates are also included for Bonneville projects to confirm wind and geothermal generation potential. Bonneville`s Geothermal Confirmation Agenda preceded implementation of RSEP, although it has a similar objective and collaborative approach.

Quick screening for new flux pinning materials in YBCO films with the combinatorial-PLD method  

NASA Astrophysics Data System (ADS)

An effective way to improve the superconducting properties in REBa2Cu3Oy (REBCO) films under a magnetic field is to dope artificial pinning centers (APC). The pinning performance depends on the content of the APC materials. Usually, the optimal APC content is explored by preparing films one at a time from the REBCO target using different APC material content, which is an extremely time-consuming process.The combinatorial-PLD (C-PLD) method allowed us to prepare films that continuously changed in composition across a single substrate. In this study, we used the C-PLD method to prepare BaSnO3 (BSO)-doped YBCO films. The films were deposited on SrTiO3 substrate using a fourth-harmonic Nd:YAG laser. From the results of the Jc-B curves at 77 K and B//c, the film that contained 3.2 vol.% of BSO exhibited the best pinning performance in this study. We showed that the C-PLD method was efficient for quick screening of the optimal APC content with only one deposition. We also used the C-PLD method to explore new APC materials, and proved that it can quickly evaluate the new APC materials Ba3Cu3In4O12 and BaTbO3.

Modeling Self-Ionized Plasma Wakefield Acceleration for Afterburner Parameters Using QuickPIC  

SciTech Connect

For the parameters envisaged in possible afterburner stages[1] of a plasma wakefield accelerator (PWFA), the self-fields of the particle beam can be intense enough to tunnel ionize some neutral gases. Tunnel ionization has been investigated as a way for the beam itself to create the plasma, and the wakes generated may differ from those generated in pre-ionized plasmas[2],[3]. However, it is not practical to model the whole stage of PWFA with afterburner parameters using the models described in [2] and [3]. Here we describe the addition of a tunnel ionization package using the ADK model into QuickPIC, a highly efficient quasi-static particle in cell (PIC) code which can model a PWFA with afterburner parameters. Comparison between results from OSIRIS (a full PIC code with ionization) and from QuickPIC with the ionization package shows good agreement. Preliminary results using parameters relevant to the E164X experiment and the upcoming E167 experiment at SLAC are shown.

Experimental program to evaluate the performance of quick-acting on/off sprinkler heads  

SciTech Connect

We evaluated the performance of new generation on/off sprinkler heads for potential use in water-sensitive areas with costly equipment, such as computer rooms and experiment control rooms, or for areas where fire-suppression water must be minimized, such as hazardous-materials holding areas. These sprinkler heads are reputed to respond quickly and shut off automatically when the fire is controlled or extinguished. We conducted a series of fire tests to analyze the ability of such quick-acting (QA) on/off sprinklers to extinguish or control fires of various strengths and fuel types; these tests were repeated with conventional sprinkler heads for comparison. Our results show that the QA on/off heads control or extinguish the gas burner and pool fires with minimal water discharge; however, when exposed to our 20-kg wood crib fire, one manufacturer's on/off sprinkler failed to operate properly in two consecutive tests. When the QA on/off heads did operate successfully, however, they discharged only 10-45% of the water needed by standard heads to control or extinguish the test fires. We are continuing to evaluate these devices to determine if they would be appropriate fire countermeasures in areas where minimal water discharge is required.

Calcium transients in skeletal muscle fibres under isometric conditions and during and after a quick stretch.  

PubMed

The transient change in the sarcoplasmic concentration of Ca2+ was measured in intact fibres isolated from the anterior tibial muscle of the frog Litoria moorei. The fibres had been injected with the calcium-sensitive dye arsenazo III and the change of the calcium concentration was calculated from the changes in light absorbance at 570, 600 and 720 nm wavelengths. Absorbance and force were measured under three different conditions: (1) during a normal isometric twitch, (2) when a quick ramp-and-hold stretch had been applied to the fibre during onset of the contraction, and (3) when the fibre was allowed to contract isometrically at a length corresponding to the final length of the stretch. A method was devised to neutralize most of the movement artefacts encountered in such measurements. While the quick stretch caused substantial increase in the level and the duration of the contractile force such as originally described in whole muscle by A. V. Hill, the calcium transients appeared basically unaffected. It thus seems that the mechanism behind the phenomenon of the force enhancement lies at a step in the excitation-contraction coupling subsequent to the calcium release. From the present results, however, it is not clear whether the phenomenon is caused by an increase in the level of activation of the calcium-dependent regulatory system, or whether it is to be found in the acto-myosin interaction itself. The latter alternative would be consistent with the stiffness measurements published earlier. PMID:1791196

Serologic Diagnosis of Human Taenia solium Cysticercosis by Using Recombinant and Synthetic Antigens in QuickELISA(TM)  

PubMed Central

Diagnosis of Taenia solium cysticercosis is an important component in the control and elimination of cysticercosis and taeniasis. New detection assays using recombinant and synthetic antigens originating from the lentil lectin-purified glycoproteins (LLGPs) of T. solium cysticerci were developed in a QuickELISA™ format. We analyzed a panel of 474 serum samples composed of 108 serum samples from donors with two or more viable cysts, 252 serum samples from persons with other parasitic infections, and 114 serum samples from persons with no documented illnesses. The sensitivities and specificities of T24H QuickELISA™, GP50 QuickELISA™, and Ts18var1 QuickELISA™ were 96.3% and 99.2%, 93.5% and 98.6%, and 89.8% and 96.4%, respectively, for detecting cases with multiple, viable cysts. T24H QuickELISA™ performs best among the three assays, and has sensitivity and specificity values comparable to those of the LLGP enzyme-linked immunosorbent blot. The QuickELISA™ are simple, rapid quantitative methods for detecting antibodies specific for T. solium cysticerci antigens.

Innovative approach for low-cost quick-access small payload missions  

NASA Astrophysics Data System (ADS)

A significant part of the burgeoning commercial space industry is placing an unprecedented number of satellites into low earth orbit for a variety of new applications and services. By some estimates the commercial space industry now exceeds that of government space activities. Yet the two markets remain largely separate, with each deploying dedicated satellites and infrastructure for their respective missions. One commercial space firm, Final Analysis, has created a new program wherein either government, scientific or new technology payloads can be integrated on a commercial spacecraft on commercial satellites for a variety of mission scenarios at a fraction of the cost of a dedicated mission. NASA has recognized the advantage of this approach, and has awarded the Quick Ride program to provide frequent, low cost flight opportunities for small independent payloads aboard the Final Analysis constellation, and investigators are rapidly developing science programs that conform to the proposed payload accommodations envelope. Missions that were not feasible using dedicated launches are now receiving approval under the lower cost Quick Ride approach. Final Analysis has dedicated ten out of its thirty-eight satellites in support of the Quick Ride efforts. The benefit of this type of space access extend beyond NASA science programs. Commercial space firms can now gain valuable flight heritage for new technology and satellite product offerings. Further, emerging international space programs can now place a payload in orbit enabling the country to allocate its resources against the payload and mission requirements rather htan increased launch costs of a dedicated spacecraft. Finally, the low cost nature provides University-based research educational opportunities previously out of the reach of most space-related budgets. This paper will describe the motivation, benefits, technical features, and program costs of the Final Analysis secondary payload program. Payloads can be accommodated on up to thirty-eight separate satellites. Since the secondary payloads will fly on satellites designed for global wireless data services, each user can utilize low cost communication system already in place for sending and retrieving digital information from its payload.

Green tea (Camellia sinensis)-associated hepatotoxicity is reported. However, the presence of alpha-1 antitrypsin MZ phenotype as a predisposing factor to green tea-associated drug-induced liver injury (DILI) is unknown. A previously healthy woman with alpha-1 antitrypsin MZ phenotype who took SlimQuick™, an herbal supplement containing green tea extract, developed severe hepatotoxicity requiring corticosteroid treatment. Green tea-associated hepatotoxicity is reviewed and alpha-1 antitrypsin MZ phenotype as a predisposing factor to green tea-associated DILI is discussed. Liver biopsy demonstrated marked inflammation with necrosis suggestive of toxic injury with diffuse alpha-1 antitrypsin globule deposition on immunostaining. Corticosteroid therapy resulted in rapid clinical improvement. Alpha-1 antitrypsin MZ phenotype may increase vulnerability to herbal hepatotoxicity. PMID:22567188

Dynamical change of structure of Rh supported on H-USY and Na-USY zeolite was measured by Quick XAFS technique operated under in situ conditions. In the atmosphere of H2, formation of the Rh clusters consist of 13 atoms was observed in H-USY and Na-USY. On the other hand, in the atmosphere of O2, formation of the highly dispersed Rh oxide was observed in H-USY, whereas Rh oxide species did not disperse in Na-USY. In the reduction processes after heating samples in the atmosphere of O2, the highly dispersed metal Rh particles in the H-USY agglomerated with increasing temperature above 553K. Whereas, the generation of stable Rh clusters were observed on the Na-USY. From these finding, it was conclude that the structure and acid sites of USY affected on the dispersion of Rh oxide particles and the generation of metal Rh clusters.

Geographic object-based delineation of neighborhoods of Accra, Ghana using QuickBird satellite imagery.  

PubMed

The objective was to test GEographic Object-based Image Analysis (GEOBIA) techniques for delineating neighborhoods of Accra, Ghana using QuickBird multispectral imagery. Two approaches to aggregating census enumeration areas (EAs) based on image-derived measures of vegetation objects were tested: (1) merging adjacent EAs according to vegetation measures and (2) image segmentation. Both approaches exploit readily available functions within commercial GEOBIA software. Image-derived neighborhood maps were compared to a reference map derived by spatial clustering of slum index values (from census data), to provide a relative assessment of potential map utility. A size-constrained iterative segmentation approach to aggregation was more successful than standard image segmentation or feature merge techniques. The segmentation approaches account for size and shape characteristics, enabling more realistic neighborhood boundaries to be delineated. The percentage of vegetation patches within each EA yielded more realistic delineation of potential neighborhoods than mean vegetation patch size per EA. PMID:20689664

Application of first-arrival tomography to characterize a quick clay landslide site in Southwest Sweden  

NASA Astrophysics Data System (ADS)

First-arrival traveltime tomography was applied to high-resolution seismic data acquired over a known quick-clay landslide scar near the Göta River in southwest Sweden in order to reveal the geometry and physical properties of clay-related normally consolidated sediments. Investigated area proved to be a challenging environment for tomographic imaging because of large P-wave velocity variations, ranging from 500 to 6000 m/s, and relatively steeply-dipping bedrock. Despite these challenges, P-wave velocity models were obtained down to ca. 150 m for two key 2D seismic profiles (each about 500-m long) intersecting over the landslide scar. The models portrait the sandwich-like structure of marine clays and coarse-grained consolidated sediments, but the estimated resolution (20 m) is too small to distinguish thin layers within this structure. Modelled velocity structures match well the results of reflection seismic processing and resistivity tomography available along the same profiles.

Gypsum-bonded investment and dental precision casting (II) investment for the quick casting technique.  

PubMed

Part I of this study presented a hypothesis that the thermal expansion of gypsum-bonded investment should become higher under heating conditions favorable for the formation of ahemihydrate. The present study aimed at proving this hypothesis by simulating the rapid heating condition employed in the quick casting technique. The expansion values obtained were 1.72-1.93% after 30 min in three investments, two rapid heating and one conventional types. Under a comparable measuring pressure a common laboratory measurement (5 degrees C/min) gave significantly lower expansions of 1.32-1.36% at 700 degrees C for the same investments (p<0.01). The shrinkage observed at 350-400 degrees C in this measurement was not observed in the rapid heating. Realistically large molds prepared from the conventional gypsum-bonded investment need to be investigated for their potentially high thermal expansion. PMID:15005229

A quick-release connector is described for securing two offshore mooring sections comprising: a pin member attached to one end of one mooring section; a latch member having a hook at one end with an open region adapted to engage the pin member and to rotate concentrically on a fixed axis substantially corresponding to the pin member when in engagement. The latch member is attached to one end of the other mooring section; a plunger adapted for axial movement between a first position, where the plunger is displaced from the open region of the hook. This permits the rotational movement of the latch, and a second position, wherein the plunger advances within the open region of the hook, prohibiting the rotational movement; means for rotating the latch member about the pin member; and means for longitudinally displacing the plunger between the first and second positions.

Liver biopsy demonstrated marked inflammation with necrosis suggestive of toxic injury with diffuse alpha-1 antitrypsin globule deposition on immunostaining. Corticosteroid therapy resulted in rapid clinical improvement. Alpha-1 antitrypsin MZ phenotype may increase vulnerability to herbal hepatotoxicity.

A simple apparatus for quick qualitative analysis of CR39 nuclear track detectors  

SciTech Connect

Quantifying the ion pits in Columbia Resin 39 (CR39) nuclear track detector from Thomson parabolas is a time consuming and tedious process using conventional microscope based techniques. A simple inventive apparatus for fast screening and qualitative analysis of CR39 detectors has been developed, enabling efficient selection of data for a more detailed analysis. The system consists simply of a green He-Ne laser and a high-resolution digital single-lens reflex camera. The laser illuminates the edge of the CR39 at grazing incidence and couples into the plastic, acting as a light pipe. Subsequently, the laser illuminates all ion tracks on the surface. A high-resolution digital camera is used to photograph the scattered light from the ion tracks, enabling one to quickly determine charge states and energies measured by the Thomson parabola.

Novel angular encoder for a quick-extended x-ray absorption fine structure monochromator  

SciTech Connect

New concepts for time-resolved x-ray absorption spectroscopy using the quick-extended x-ray absorption fine structure (QEXAFS) method are presented. QEXAFS is a powerful tool to gain structural information about, e.g., fast chemical reactions or phase transitions on a subsecond scale. This can be achieved with a monochromator design that employs a channel-cut crystal on a cam driven tilt table for rapid angular oscillations of the Bragg angle. A new angular encoder system and a new data acquisition were described and characterized that were applied to a QEXAFS monochromator to get spectra with a directly measured accurate energy scale. New electronics were designed to allow a fast acquisition of the Bragg angle values and the absorption data during the measurements simultaneously.

[Development of dental quick casting with zircon-phosphoric acid investments].  

PubMed

The application of zircon (ZrSiO4) that has high refractoriness, high thermal conductivity and a low coefficient of thermal expansion, to quick casting investment was studied. Various zircon powders and phosphoric acid solutions were tested with respect to the higher thermal shock resistance. The formulation and properties of zircon-phosphoric acid investment materials such as water/powder ratio, fluidity of slurry, setting time, setting expansion, thermal expansion, thermal analysis, green and fired compressive strength were measured. Formulation of zircon slurry for coating was zircon flower #600 30%, zircon flower #350 10%, and zircon sand CP 60%, and that for sanding was zircon flower #200. The mixing liquid was 15% phosphoric acid and liquid/powder ratio was 0.1. The slurry using phosphoric acid had good fluidity and good workability. The 24-hour green strength was 1 MPa, fired strength was 10 MPa, 24-hour setting expansion was -0.04% and the thermal expansion at 1000 degrees C was 0.31%. Immediately after coating with zircon slurry, the coating layer was dried, sintered and dewaxed by thermal shock. The thermal shock consisted of the following four-step manipulations. The first is hot air drying (50 degrees C, 5 minutes), the second is heat shock (900 degrees C, 3 seconds), the third is redrying (220 degrees C, 3 minutes) and the fourth is dewaxing (550 degrees C, 3 minutes). Small casting of pure titanium and K-metal could be done successfully by the quick casting method using the zircon-phosphoric acid investments. It was found that the total expansion of the secondary investments influenced the casting adapatability. PMID:2135526

This manual augments the detailed manual of the GW-BASIC version of the LTC code for an application in QuickBASIC. As most of the GW-BASIC coding of this program for ``LMR Transient Calculations`` is compatible with QuickBASIC, this manual pertains primarily to the required changes, such as the handling of input and output. The considerable reduction in computation time achieved by this conversion is demonstrated for two sample problems, using a variety of hardware and execution options. The revised code is listed. Although the severe storage limitations of GW-BASIC no longer apply, the LOF transient path has not been completed in this QuickBASIC code. Its advantages are thus primarily in the much faster running time for TOP and LOHS transients. For the fastest PC hardware (486) and execution option the computation time is reduced by a factor of 124 compared to GW-BASIC on a 386/20.

Substitution of valine for glycine-558 in the congenital dysthrombin thrombin Quick II alters primary substrate specificity  

SciTech Connect

Thrombin Quick II is one of two dysfunctional forms of thrombin derived from the previously described congenital dysprothrombin prothrombin Quick. Thrombin Quick II does not clot fibrinogen, hydrolyze p-nitroanilide substrates of thrombin, or bind N{sup 2}-(5-(dimethylamino)naphthalene-1-sulfonyl)arginine N,N-(3-ethyl-1,5-pentanediyl)amide, a high-affinity competitive inhibitor of thrombin. To determine the structural alteration in thrombin Quick II, the reduced, carboxymethylated protein was hydrolyzed by a lysyl endopeptidase. A peptide not present in a parallel thrombin hydrolysate was identified by reverse-phase chromatography. This Gly residue, which is highly conserved in the chymotrypsin family of serine proteases, forms part of the substrate binding pocket for bulky aromatic and basic side chains in chymotrypsin and trypsin, respectively. However, in porcine elastase 1, the corresponding residue is threonine. Consistent with the identified structural alteration, thrombin Quick II incorporates ({sup 3}H)diisopropyl fluorophosphate stoichiometrically and hydrolyzes the elastase substrate succinyl-Ala-Ala-Pro-Leu-p-nitroanilide with a relative k{sub cat}/K{sub M} of 0.14 when compared to thrombin. This results from a 3-fold increase in K{sub M} and a 2.5-fold decrease in k{sub cat} for thrombin Quick II when compared to thrombin acting on the same substrate. These results and those of other investigators studying mutant trypsins support the conclusion that the catalytic activity of serine proteases is very sensitive to structural alterations in the primary substrate binding pocket.

Detection of urban expansion in an urban-rural landscape with multitemporal QuickBird images  

PubMed Central

Accurately detecting urban expansion with remote sensing techniques is a challenge due to the complexity of urban landscapes. This paper explored methods for detecting urban expansion with multitemporal QuickBird images in Lucas do Rio Verde, Mato Grosso, Brazil. Different techniques, including image differencing, principal component analysis (PCA), and comparison of classified impervious surface images with the matched filtering method, were used to examine urbanization detection. An impervious surface image classified with the hybrid method was used to modify the urbanization detection results. As a comparison, the original multispectral image and segmentation-based mean-spectral images were used during the detection of urbanization. This research indicates that the comparison of classified impervious surface images with matched filtering method provides the best change detection performance, followed by the image differencing method based on segmentation-based mean spectral images. The PCA is not a good method for urban change detection in this study. Shadows and high spectral variation within the impervious surfaces represent major challenges to the detection of urban expansion when high spatial resolution images are used.

Reconstruction of cranial bone defects using a quick-setting hydroxyapatite cement and absorbable plates.  

PubMed

We examine the 6-month histology of a quick-setting hydroxyapatite cement (Mimix), with and without absorbable plates (LactoSorb), after placement in critical size defects made in the skull of 20 New Zealand white rabbits. Two 10-mm-diameter parietal defects were made in each rabbit. One defect was placed on each side of the sagittal suture. In 10 animals, the left defect was filled with Mimix alone, and in the other 10, an absorbable plate was placed across the base of the left defect before Mimix placement. The right-sided defect served as a control in all animals, with no material placed in or across this defect. The rabbits were killed 6 months postoperatively. A bone pathologist performed histologic examinations of the specimens looking specifically for evidence of inflammatory reaction and bone formation. There was no inflammation around the dura or any other negative histologic reaction in either the study groups or the control. Growth of new bone into the Mimix was found along the periphery in all specimens. We found no migration or displacement of the Mimix from any of the calvarial defects. PMID:18650747

Quick Synthesis of Carbon Nitride Films by New DC Hollow Cathode Plasma Sputtering Deposition Technique  

NASA Astrophysics Data System (ADS)

High N content of carbon nitride films are quickly deposited onto Si (100) substrates at room temperature by using DC hollow cathode plasma sputtering deposition technique. The deposition rate is up to 283 nm/min at the bias voltage of 400 V. The properties of the films are characterized by using XPS, Raman (scattering) and Fourier transformation infrared (FTIR) spectroscopy. Experiments results provide direct evidences that the structures of CN films can be controlled by regulating bias voltages. The maximum sp3C-N concentration up to 0.73 is obtained. Raman data is used to confirm XPS results. FTIR of the films clearly show C-N and C=N components (1000-1800 cm-1) together with a tiny peak C?N (2181 cm-1). By reducing particle energy and substrate temperature, we have succeeded in suppressing the mechanisms of losing N-contain species during deposition, and achieved a large amount of sp3 bonds of CN films.

[Quick radioimmunoassay for plasma immunoreactive insulin (IRI)--application for localizing occult insulinoma during operation].  

PubMed

A quick RIA for IRI was developed which can be applied for localizing occult insulinoma during extirpation of the tumor. We used anti-insulin antibody insolubilized with bacterial cell wall. The standard solutions were prepared by dissolving porcine insulin in human plasma containing low level of IRI. By use of this assay IRI in plasma samples are assayed within 45 min for 20 samples including standard samples. The coefficient of variation of intra- and inter-assay were 9-19% and the recovery tests were 70-120%. The assay has a sensitivity of 10 microU/ml. The obtained IRI values by this method correlated well with those by the usual method (Insulin RIA Bead) (y=1.0 x -0.2, r = 0.98). A clinical case with insulinoma was shown in which the localization of the tumor was diagnosed from IRI levels in various portions of splenic vein assayed by this method during the operation and the tumor was extirpated successfully.

Production and shelf stability of multiple-fortified quick-cooking rice as a complementary food.  

PubMed

Rice-based complementary foods normally contain inadequate amounts of several micronutrients, such as iron, calcium, and zinc. This study aimed at improving the quality of commercially produced rice-based complementary foods. The analysis centered on identifying a rice-based complementary food that is safe, stable, sensory acceptable, and economical in terms of fortificants (iron, calcium, zinc, thiamine, folate) and effectively packaged for industrial production and distribution. Product colors were mostly in green-yellow tone and slightly changed to more yellow during storage. Sensory acceptability was affected by changes in odor and rancidity but not in color. Rancidity scores were low in aluminum foil laminated plastic bags (ALU). Lipid oxidation significantly increased during storage, but at a slower rate when sodium citrate and ALU were used. Color differences of raw products were detected but not in the cooked ones. Mineral and vitamin losses during processing were 2% to 11% and 20% to 30%, respectively, but no losses were found during storage. FeSO(4)+ NaFeEDTA added with sodium citrate resulted in the most acceptable product for all packagings. The multiple-fortified quick-cooking rice (MFQCR) developed from this study could be a potentially useful tool for combating micronutrient deficiencies among infants and young children in the countries where rice is the staple food.

The coelomic envelope of Xenopus laevis eggs: a quick-freeze, deep-etch analysis.  

PubMed

The extracellular matrix of Xenopus laevis oocytes was analyzed before and after meiotic maturation using quick-freeze, deep-etch, rotary-shadow electron microscopy. The perivitelline space (PS) of the meiotically immature oocyte contains a filamentous network which connects microvilli (MV) and follicle cell macrovilli to the folded oocyte surface below. The envelope overlying the PS is composed of bundles of large fibers which course between the tips of the MV. Spaces between these bundles contain smaller fibrils which secure the egg envelope to the microvillar tips. Meiotic maturation is accompanied by flattening of the oocyte plasma membrane, formation of an orderly array of MV, and elevation of the egg envelope. In the coelomic eggs, the reorganized envelope is composed of loosely bundled large fibers which course above the microvillar tips rather than between them. The spaces between these bundles contain small fibers similar to those seen in the meiotically immature oocyte. This reorganized envelope, however, will not bind sperm; further modifications must transpire during passage through the oviduct to render it sperm receptive. PMID:2909400

Final Phase II report : QuickSite(R) investigation, Everest, Kansas.  

SciTech Connect

The Commodity Credit Corporation (CCC), an agency of the U.S. Department of Agriculture (USDA), operated grain storage facilities at two different locations at Everest, Kansas (Figure 1.1). One facility (referred to in this report as the Everest facility) was at the western edge of the city of Everest. The CCC/USDA operated this facility from 1950 until the early 1970s. The second facility (referred to in this report as Everest East) was about 0.5 mi northeast of the town. The CCC/USDA operated this facility from 1954 until the early 1970s. While these two former CCC/USDA grain storage facilities were in operation, commercial grain fumigants containing carbon tetrachloride were in common use by the CCC/USDA and the private grain storage industry to preserve grain. In 1997, the Kansas Department of Health and Environment (KDHE) sampled several domestic drinking water and nondrinking water wells in the Everest area. The KDHE sampling was part of the CCC/USDA Private Well Sampling Program, which was initiated to determine whether carbon tetrachloride was present in domestic wells near former CCC/USDA grain storage facilities in Kansas. All of the sampled domestic drinking water wells were located outside the Everest city boundaries. As a result of this sampling, carbon tetrachloride contamination was identified at a single domestic drinking water well (the Nigh well; DW06) approximately 3/8 mi northwest of the former Everest CCC/USDA grain storage facility. The CCC/USDA subsequently connected the Nigh residence to the Everest municipal water system. As a result of the detection of carbon tetrachloride in this well, the KDHE conducted preliminary investigations to further evaluate the existence of contamination and its potential effect on public health and the environment. The KDHE concluded that carbon tetrachloride in groundwater at Everest might, in part, be linked to historical use of carbon tetrachloride-based grain fumigants at the former CCC/USDA facilities. For this reason, the CCC/USDA is conducting an environmental site investigation to determine the source(s) and extent of the carbon tetrachloride contamination at Everest and to assess whether the contamination requires remedial action. The investigation at Everest is being performed by the Environmental Research Division of Argonne National Laboratory. Argonne is a nonprofit, multidisciplinary research center operated by the University of Chicago for the U.S. Department of Energy (DOE). The CCC/USDA has entered into an interagency agreement with DOE, under which Argonne provides technical assistance to the CCC/USDA with environmental site characterization and remediation at its former grain storage facilities. At these facilities, Argonne is applying its QuickSite{reg_sign} environmental site characterization methodology. This methodology has been applied successfully at a number of former CCC/USDA facilities in Kansas and Nebraska and has been adopted by the American Society for Testing and Materials (ASTM 1998) as standard practice for environmental site characterization. Phase I of the QuickSite{reg_sign} investigation examined the key geologic, hydrogeologic, and hydrogeochemical relationships that define potential contaminant migration pathways at Everest (Argonne 2001). Phase II of the QuickSite{reg_sign} investigation at Everest was undertaken with the primary goal of delineating and improving understanding of the distribution of carbon tetrachloride contamination in groundwater at this site and the potential source area(s) that might have contributed to this contamination. To address this goal, four specific technical objectives were developed to guide the Phase II field studies. Sampling of near-surface soils at the former Everest CCC/USDA facility that was originally planned for Phase I had to be postponed until October 2000 because of access restrictions. Viable vegetation was not available for sampling then. This period is termed the first session of Phase II field work at Everest.

Evaluation of removal efficiency of fluoride from aqueous solution using quick lime.  

PubMed

Several methods are available to remove fluoride from the aqueous environment but they are not feasible in all places and conditions due to various reasons. In the present work, F(-) has been removed by using activated and ordinary quick lime. The removal of fluoride was 80.6% and the final concentration was 9.7 mg/L at optimum condition from the synthetic solution having initial fluoride concentration of 50 mg/L. Adsorption kinetic study revealed that the adsorption process followed first order kinetics. And the removal process followed Langmuir adsorption isotherm. The SEM micrographs and XRD studies revealed that the removal of fluoride was mainly due to chemi-sorption and precipitation. However, they can be suitably used to remove fluoride from industrial effluent where the concentration is high. But this method cannot be employed to treat water for domestic purpose, since it cannot bring fluoride within permissible limit and also increases the pH of treated water. PMID:17046155

Quick selection of a chimeric T2 phage that displays active enzyme on the viral capsid.  

PubMed

We designed a bacteriophage T2 system to display proteins fused at the N-terminus of the head protein small outer capsid (SOC) of a T2 phage. To facilitate selection of chimeric phage, a T2 phage encoding the beta-galactosidase gene (betagal) upstream of the soc gene was constructed. The phage, named T2betaGal, produces blue plaques on agar plates containing XGal. Subsequently, a plasmid encoding the target protein upstream of soc was constructed and used to transform E. coli B(E) cells. Transformed cells were infected with T2betaGal and homologous recombination between phage DNA and the plasmid resulted in a chimeric phage that produced transparent plaques due to the excision of the betagal gene. Chitosanase of Bacillus sp. strain K17 (ChoK), consisting of 453 amino acids, was used as a model target protein. Recombinant T2 phage that produced ChoK was named T2ChoK. T2ChoK was produced from T2betaGal at a recombination frequency of about 0.1%. On the other hand, the value for T2betaGal produced from wild-type T2 was 0.001 %. This new system enables us to select recombinant phage very quickly and accurately. The number of molecules of ChoK was calculated at 14.7 per single phage. Latent period and burst size were estimated for the chimeric phages. PMID:16321064

A quick method for computing approximate thresholds for quantitative trait loci detection.  

PubMed Central

This article proposes a quick method for computing approximate threshold levels that control the genome-wise type I error rate of tests for quantitative trait locus (QTL) detection in interval mapping (IM) and composite interval mapping (CIM). The procedure is completely general, allowing any population structure to be handled, e.g., BC(1), advanced backcross, F(2), and advanced intercross lines. Its main advantage is applicability in complex situations where no closed form approximate thresholds are available. Extensive simulations demonstrate that the method works well over a range of situations. Moreover, the method is computationally inexpensive and may thus be used as an alternative to permutation procedures. For given values of the likelihood-ratio (LR)-profile, computations involve just a few seconds on a Pentium PC. Computations are simple to perform, requiring only the values of the LR statistics (or LOD scores) of a QTL scan across the genome as input. For CIM, the window size and the position of cofactors are also needed. For the approximation to work well, it is suggested that scans be performed with a relatively small step size between 1 and 2 cM.

The Virtual Space Physics Observatory: Quick access to Data and Tools  

NASA Astrophysics Data System (ADS)

The Virtual Space Physics Observatory (VSPO; http://vspo.gsfc.nasa.gov) has grown to provide a way to find and access about 375 data products and services from over 100 spacecraft/observatories in space and solar physics. The datasets are mainly chosen to be the most requested, and include most of the publicly available data products from operating NASA Heliophysics spacecraft as well as from solar observatories measuring across the frequency spectrum. Service links include a "quick orbits" page that uses SSCWeb Web Services to provide a rapid answer to questions such as "What spacecraft were in orbit in July1992?" and "Where were Geotail, Cluster, and Polar on 2 June 2001?" These queries are linked back to the data search page. The VSPO interface provides many ways of looking for data based on terms used in a registry of resources using the SPASE Data Model that will be the standard for Heliophysics Virtual Observatories. VSPO itself is accessible via an API that allows other applications to use it as a Web Service; this has been implemented in one instance using the ViSBARD visualization program. The VSPO will become part of the Space Physics Data Facility, and will continue to expand its access to data. A challenge for all VOs will be to provide uniform access to data at the variable level, and we will be addressing this question in a number of ways.

Analysis and Development of a Quick Acting Diaphragm-less Shock Tube Driver  

NASA Astrophysics Data System (ADS)

This work discusses the construction and performance characteristics of a diaphragmless shock tube driver. Shock waves play integral roles in many industrial, medical and scientific environments, consequently it is important to observe the behaviour of these waves and how they interact with their surroundings. The diaphragmless shock tube provides a quick and effective means of producing shock waves in gases. The major advantages compared to conventional diaphragms include, minimal downtime between repeated experiments, opening times comparable to those of conventional diaphragms and infinitely adjustable opening pressure without the use of various diaphragm thicknesses. Moreover, the diaphragmless design also eliminates fragments that are carried downstream of the shock tube once the conventional diaphragm is ruptured. The design utilized in this work is built on that of Downey et al. [M.S. Downey, T.J. Cloete, A.D.B.Yates, Shock Waves 21(4): 315-319, 2011] and is improved in order to obtain faster opening times leading to stronger shock formation. Furthermore in depth numerical analysis using the commercial CFD package Fluent is carried out to validate experimental data for driven pressures and opening times as a function of driver pressure.

Quick Exposure Check (QEC): a cross-cultural adaptation into Brazilian-Portuguese.  

PubMed

Most instruments used by occupational safety and health professionals have been originally developed in English. Cross-cultural adaptation enables the use of these instruments in other countries, cultures and languages in countries like Brazil, where the official language is not English. This methodology ensures that the translation process includes the cultural and linguistic equivalence between the original instrument and the translated version. Therefore, this study aimed to translate and cross-culturally adapt the instrument Quick Exposure Check (QEC) into Brazilian-Portuguese. The process of cross-cultural adaptation followed the steps of translation, synthesis, back-translation, expert committee review and pretesting. The final questionnaire was pretested by two raters in 40 workers employed in an expedition of knitting and textile industry. All versions resulting from the translation process (T1, T2) and back-translation (BT1, BT2) showed good agreement. During the pre-test was not presented any difficulty in understanding or completing the instrument adapted QEC for Brazilian language. PMID:22317019

Alzheimer's Prevention Initiative: a proposal to evaluate presymptomatic treatments as quickly as possible  

PubMed Central

Now is the time to launch the era of Alzheimer’s disease (AD) prevention research, establish the methods and infrastructure to rapidly evaluate presymptomatic AD treatments and evaluate them rigorously and rapidly in randomized clinical trials. This article is a call to arms. It contends that the evaluation of presymptomatic AD treatments must become an urgent priority, it identifies what is holding us back and proposes new public policies and scientific strategies to overcome these roadblocks. It defines the term ‘presymptomatic AD treatment,’ notes the best established biomarkers of AD progression and pathology and suggests how they could be used to rapidly evaluate presymptomatic AD treatments in the people at risk. It introduces an approach to evaluate presymptomatic AD treatments in asymptomatic people at the highest risk of imminent clinical onset and determines the extent to which the treatment’s biomarker predicts a clinical outcome. We propose an Alzheimer’s Prevention Initiative, which is now being reviewed and refined in partnership with leading academic and industry investigators. It is intended to evaluate the most promising presymptomatic AD treatments, help develop a regulatory pathway for their accelerated approval using reasonably likely surrogate end points and find demonstrably effective presymptomatic AD treatments as quickly as possible.

[Research on pixel decomposition of QuickBird multi-spectrum band images].  

PubMed

In the condition that the DN(Digital Number) value images of ground-atmosphere system recorded by the QuickBird artificial satellite sensor were taken as the experimental datum, the equation of pixel decomposition was structured, abiding by energy conservation law and the proportional relationship between the sum of 1-4 band integral radiance and the panchromatic band (Pan) integral radiance. By using the equation gained above, every pixel of 1-4 band images was decomposed into sixteen pixels. So the high resolution 1-4 band radiance images with the resolution of 0.61 m were finally obtained in this experiment. Compared with the original 1-4 band images, the spatial resolution of the high resolution 1-4 band radiance images was raised by four times. The detailed characteristics of the surface features in the high resolution 1-4 band radiance images were more limpid than the original 1-4 band images. The optesthesia effect was also improved obviously in the high resolution 1-4 band radiance images. Therefore, the map with appropriate scale improved from 1 : 10 000 to 1 : 2 500 can be made based on the high resolution 1-4 band radiance images. PMID:20101998

Alzheimer's prevention initiative: a proposal to evaluate presymptomatic treatments as quickly as possible.  

PubMed

Now is the time to launch the era of Alzheimer's disease (AD) prevention research, establish the methods and infrastructure to rapidly evaluate presymptomatic AD treatments and evaluate them rigorously and rapidly in randomized clinical trials. This article is a call to arms. It contends that the evaluation of presymptomatic AD treatments must become an urgent priority, it identifies what is holding us back and proposes new public policies and scientific strategies to overcome these roadblocks. It defines the term 'presymptomatic AD treatment', notes the best established biomarkers of AD progression and pathology and suggests how they could be used to rapidly evaluate presymptomatic AD treatments in the people at risk. It introduces an approach to evaluate presymptomatic AD treatments in asymptomatic people at the highest risk of imminent clinical onset and determines the extent to which the treatment's biomarker predicts a clinical outcome. We propose an Alzheimer's Prevention Initiative, which is now being reviewed and refined in partnership with leading academic and industry investigators. It is intended to evaluate the most promising presymptomatic AD treatments, help develop a regulatory pathway for their accelerated approval using reasonably likely surrogate end points and find demonstrably effective presymptomatic AD treatments as quickly as possible.

Quick-look eye-safety assessment for the short range lidar  

SciTech Connect

This is a quick-look eye-safety assessment for the Short Range (SR) lidar, a system under development for standoff biological aerosol detection in the outdoor environment. The ground-vehicle-mounted SR lidar system will scan a sector of the nearby atmosphere with a repetitively pulsed, multiple-wavelength, UV/IR laser beam. This laser is not intrinsically eye-safe, and hence the SR lidar system requires a protection system to minimize the risk of eye exposures above the ANSI-standard maximum permissible exposure within a nominal hazard zone. The nominal ocular hazard distance for the UV/IR laser itself was calculated to be 6 km. The protection system, which will include a scan-stop detector and a laser beam path interrogator, currently is conceptual only. Until the complete protection system is designed, evaluated, and tested, and a more detailed safety assessment has been performed, the eye-safety issue for the SR lidar system cannot be resolved.

Object-based classification of residential land use within Accra, Ghana based on QuickBird satellite data  

PubMed Central

A segmentation and hierarchical classification approach applied to QuickBird multispectral satellite data was implemented, with the goal of delineating residential land use polygons and identifying low and high socio-economic status of neighbourhoods within Accra, Ghana. Two types of object-based classification strategies were tested, one based on spatial frequency characteristics of multispectral data, and the other based on proportions of Vegetation–Impervious–Soil sub-objects. Both approaches yielded residential land-use maps with similar overall percentage accuracy (75%) and kappa index of agreement (0.62) values, based on test objects from visual interpretation of QuickBird panchromatic imagery.

Development of quick and accurate automatic hypocenter location system for the earthquake alarm  

NASA Astrophysics Data System (ADS)

Most earthquake damage occurs after arrival of the S wave, whose amplitude is about five times larger than the P wave. Because the P wave travels faster than the S wave, the interval between their arrival times creates an opportunity to activate an earthquake alarm and take preemptive safety measures. We developed an automatic system which transmits the earthquake shaking intensity before S wave arrival. Since the alarm system is used to control transportation, industry, business, etc, at a time of a large earthquake occurrence, false alarms cost huge. We solved the technical difficulty of determining earthquake parameters very quickly and without errors, by developing a novel method using not only P wave arrival times but also time data of P wave not yet arrived. We also developed filters which can distinguish seismic signal from large amplitude noise generated by many kinds of reasons. The system can eliminate extraneous arrival-time readings during the process of hypocenter location by checking automatically measured readings, P wave not yet arrived data, and their station distribution. We use waveform data of Hi-net (High Sensitivity Seismograph Network Japan, National Research Institute for Earth Science and Disaster Prevention) composed of ca. 700 very high quality stations covering whole Japan with space density of 20 to 30 km. All seismometers are installed on observation wells deeper than 100m. Our system can locate precise hypocenters for 97 % felt events occurring in and near Japan Islands within a few seconds and transmits earthquake alarm information before most of seismic energy has arrived even to the station closest to the hypocenter. We are broadcasting earthquake alarm information for all destructive earthquakes by using the satellite system developed by ERI (Earthquake Research Institute, Univ. of Tokyo), and hoping to promote the development of many kinds of automatic control systems which stop cars, factories, etc to protect people from earthquake damage.

Dealing with locally-driven degradation: A quick start option under REDD+.  

PubMed

The paper reviews a number of challenges associated with reducing degradation and its related emissions through national approaches to REDD+ under UNFCCC policy. It proposes that in many countries, it may in the short run be easier to deal with the kinds of degradation that result from locally driven community over-exploitation of forest for livelihoods, than from selective logging or fire control. Such degradation is low-level, but chronic, and is experienced over very large forest areas. Community forest management programmes tend to result not only in reduced degradation, but also in forest enhancement; moreover they are often popular, and do not require major political shifts. In principle these approaches therefore offer a quick start option for REDD+. Developing reference emissions levels for low-level locally driven degradation is difficult however given that stock losses and gains are too small to be identified and measured using remote sensing, and that in most countries there is little or no forest inventory data available. We therefore propose that forest management initiatives at the local level, such as those promoted by community forest management programmes, should monitor, and be credited for, only the net increase in carbon stock over the implementation period, as assessed by ground level surveys at the start and end of the period. This would also resolve the problem of nesting (ensuring that all credits are accounted for against the national reference emission level), since communities and others at the local level would be rewarded only for increased sequestration, while the national reference emission level would deal only with reductions in emissions from deforestation and degradation.

Influenza virological surveillance in children: the use of the QuickVue rapid diagnostic test.  

PubMed

New rapid diagnostic methods are needed to identify influenza infections to improve virological surveillance usually undertaken with conventional time-consuming, complex, and even expensive laboratory methods. Another reason for using a rapid test is to avoid inappropriate therapy, particularly in children, where use of antibiotics inappropriately and high influenza-related rates of hospitalisation are described. During two winter seasons, the performance of the QuickVue Influenza test (QV) was evaluated in children under 14 presenting with influenza like illness, and compared the results with those obtained from sentinel network surveillance using standard protocols for the sample collection and the laboratory analysis by virus culture and reverse transcription-polymerase chain reaction (RT-PCR). During the first influenza season (2000/2001), 22 paediatricians collected one nose- and one throat-swab from each of the 586 children 0-6 years old recruited in the study. The QV test was carried out in the physician's office by primary care staff on the nose swab material. When compared with virus culture of the throat swab, the QV test had a sensitivity of 36.5%. In the following 2001/2002-influenza season, the performance of the QV test as a rapid laboratory screening assay was assessed. 342 children aged 0-14 years were enrolled with only one throat swab collected from each patient and sent to the laboratory where the QV, virus culture, and RT-PCR tests were performed. The results showed a better sensitivity (54.5%) of the test in comparison with virus culture and RT-PCR assays. The data indicate that rapid QV testing in the physician office setting, using these easily obtained samples, may be too insensitive to be useful for surveillance and for immediate clinical management of children presenting with influenza-like illness. Nevertheless, the QV test may be a valuable diagnostic tool if used in laboratory, as a rapid screening test. PMID:15122803

The quick acquisition technique for laser communication between LEO and GEO  

NASA Astrophysics Data System (ADS)

The sight-axis alignment can be accomplished by the quick acquisition operation between two laser communication terminals, which is the premise of establishing a free-space optical communication link. Especially for the laser communication links of LEO (Low Earth Orbit)-Ground and LEO-GEO (Geostationary Earth Orbit), since the earth would break the transmission of laser and break the communication as well, so the effective time for each communication is very shot (several minutes~ dozens of minutes), as a result the communication terminals have to capture each other to rebuild the laser communication link. In the paper, on the basis of the analysis of the traditional methods, it presents a new idea that using the long beacon light instead of the circular beacon light; thereby the original of two-dimensional raster spiral scanning is replaced by one-dimensional scanning. This method will reduce the setup time and decrease the failure probability of acquisition for the LEO-GEO laser communication link. Firstly, the analysis of the external constraint conditions in the acquisition phase has been presented in this paper. Furthermore, the acquisition algorithm models have been established. The optimization analysis for the parameters of the acquisition unit has been carried out, and the ground validation experiments of the acquisition strategy have also been performed. The experiments and analysis show that compared with traditional capturing methods, the method presented in this article can make the capturing time be shortened by about 40%, and the failure probability of capturing be reduced by about 30%. So, the method is significant for the LEO-GEO laser communication link.

Nucleation and aggregative growth process of platinum nanoparticles studied by in situ quick XAFS spectroscopy.  

PubMed

The early stage in the nucleation and subsequent aggregative particle growth of the colloidal platinum (Pt) dispersions produced by photoreduction in an aqueous ethanol solution of poly(N-vinyl-2-pyrrolidone) (PVP) was quantitatively investigated by means of in situ quick XAFS (QXAFS) measurements. The stages of the reduction-nucleation and the association process (aggregative particle growth and Ostwald ripening) of Pt atoms to produce Pt nanoparticles was successfully discriminated in course of the photoreduction time. The present QXAFS analysis indicated that Pt nuclei (i.e., (Pt(0))(m) nucleates approximately m = 4) were continuously produced in the reduction-nucleation process at the early time, followed by the aggregative particle growth with the autocatalytic reduction of Pt ionic species on the surface of Pt nuclei to produce Pt nanoparticles. Subsequently the particle growth proceeded via Ostwald ripening, resulting in the production of larger Pt nanoparticles at a later time. It was also found that the aggregative particle growth follows a sigmoidal profile well described either by the solid-state kinetic model or by the chemical-mechanism-based kinetic model, specifically the Avrami-Erofe'ev or Finke-Watzky models. The difference in terms of the formation mechanism was observed between the reduction of Pt(IV)Cl(6)(2-) and Pt(II)Cl(4)(2-) as a source material. Also presented is that the addition of the photoactivator such as benzoin, benzophenone, and acetophenone in the system is very effective to enhance the rate for the formation of Pt nanoparticles.

A new flexible monochromator setup for quick scanning x-ray absorption spectroscopy  

SciTech Connect

A new monochromator setup for quick scanning x-ray absorption spectroscopy in the subsecond time regime is presented. Novel driving mechanics allow changing the energy range of the acquired spectra by remote control during data acquisition for the first time, thus dramatically increasing the flexibility and convenience of this method. Completely new experiments are feasible due to the fact that time resolution, edge energy, and energy range of the acquired spectra can be changed continuously within seconds without breaking the vacuum of the monochromator vessel and even without interrupting the measurements. The advanced mechanics are explained in detail and the performance is characterized with x-ray absorption spectra of pure metal foils. The energy scale was determined by a fast and accurate angular encoder system measuring the Bragg angle of the monochromator crystal with subarcsecond resolution. The Bragg angle range covered by the oscillating crystal can currently be changed from 0 deg. to 3.0 deg. within 20 s, while the mechanics are capable to move with frequencies of up to ca. 35 Hz, leading to ca. 14 ms/spectrum time resolution. A new software package allows performing programmed scan sequences, which enable the user to measure stepwise with alternating parameters in predefined time segments. Thus, e.g., switching between edges scanned with the same energy range is possible within one in situ experiment, while also the time resolution can be varied simultaneously. This progress makes the new system extremely user friendly and efficient to use for time resolved x-ray absorption spectroscopy at synchrotron radiation beamlines.

Comparison study of QuickCast versus a traditional thermoplastic in the fabrication of a resting hand splint.  

PubMed

Therapists are frequently presented with new splinting material promising better and faster results. Managed care and cost containment make it important to evaluate the splinting materials used in the fabrication process. A new precut splint, QuickCast, is made from a fiberglass material that becomes pliable from the heat of a standard household hair dryer. Graduate occupational therapy students participated in timed trials fabricating resting hand splints with QuickCast and Ezeform brands of thermoplastic. Second-year occupational therapy students chosen as splint makers answered a questionnaire measuring fit, edges, strap application, aesthetics, safety, and ease of positioning. First-year students who had no neurologic or orthopedic involvement in the upper extremities participated as clients. They answered a questionnaire on comfort, weight, and aesthetics of the splint and the safety and comfort of the splinting process. Analysis of timed trials revealed no significant difference in the time required to fabricate the QuickCast precut thermoplastic and the sheet thermoplastic splints. From the questionnaire, the thermoplastic splint was rated safer than the QuickCast material by splint makers. Further studies are suggested for comparing time and cost effectiveness between commercially available splinting materials. PMID:9493798

Assessment of the NeQuick model at mid-latitudes using GNSS TEC and ionosonde data  

NASA Astrophysics Data System (ADS)

The modelling of the total electron content (TEC) plays an important role in global navigation satellite systems (GNSS) accuracy, especially for single-frequency receivers, the most common ones constituting the mass market. For the latter and in the framework of Galileo, the NeQuick model has been chosen for correcting the ionospheric error contribution and will be integrated into a global algorithm providing the users with daily updated information. In order to reach the ionosphere error correction level objective, the model itself as well as its use for Galileo are investigated. In our comparison process, we take advantage of various ionosphere data from several European stations (Dourbes in Belgium, El Arenosillo and Roquetes in Spain) where ionosonde and GPS TEC data are available for different solar activity levels. These data allow us to study NeQuick representation of the ionosphere at mid-latitudes. Constraining the model with ionosonde measurements, we investigate the difference between GPS-derived vertical TEC and corresponding values from NeQuick for a high solar activity level (year 2002). With this approach, we reach residual errors of less than 20% in standard deviation. We especially highlight the improvements from the latest (second) version of NeQuick and show the critical importance of the topside formulation.

Fusion of RADARSAT fine-beam SAR and QuickBird data for land-cover mapping and change detection  

NASA Astrophysics Data System (ADS)

The objective of this research is to evaluate multitemporal RADARSAT Fine-Beam C-HH SAR data, QuickBird MS data, and fusion of SAR and MS for urban land-cover mapping and change detection One scene of QuickBird imagery was acquired on July 18, 2002 and five-date RADARSAT fine-beam SAR images were acquired during May to August in 2002. Landsat TM imagery from 1988 was used for change detection. QucikBird images were classified using an object-based and rule-based approach. RADARSAR SAR texture images were classified using a hybrid approach. The results demonstrated that, for identifying 19 land-cover classes, object-based and rule-based classification of Quickbird data yielded an overall classification accuracy of 86.7% (kappa 0.857). For identifying 11 land-cover classes, ANN classification of the combined Mean, Standard Deviation and Correlation texture images yielded an overall accuracy: 71.4%, (Kappa: 0.69). The hybrid classification of RADARSAT fine-beam SAR data improved the ANN classification accuracy to 83.56% (kappa: 0.803). Decision level fusion of RADARSAT SAR and QuickBird data improved the classification accuracy of several land cover classes. The post-classification change detection was able to identify the areas of significant change, for example, major new roads, new low-density and high-density builtup areas and golf courses, even though the change detection results contained large amount of noise due to classification errors of individual images. QuickBrid classification result was able add detailed change information to the major changes identified.

PubMed Central

Pulmonary toxicity is one of the most serious adverse effects associated with a quick course of vincristine, bleomycin, and cisplatin neoadjuvant chemotherapy (NAC-VBP). The aim of this study was to evaluate pulmonary toxicity related to a quick course NAC-VBP. A total of consecutive 61 patients, who underwent at most 3 cycles of NAC-VBP every 10 days in the International Federation of Gynecology and Obstetrics (FIGO) stage IB-IIB cervical cancer from 1995 to 2007, were retrospectively analyzed. Of the 61 study subjects, 7 (11.5%) were identified to have pulmonary toxicity and 2 (3.3%) died of pulmonary fibrosis progression despite aggressive treatment and the use of a multidisciplinary approach. No factor predisposing pulmonary toxicity was identified. Initial symptoms were non-specific, but bronchiolitis obliterans organizing pneumonia and interstitial pneumonitis were characteristic findings by high-resolution computed tomography of the chest. The benefit of steroid therapy was uncertain and was associated with steroid-induced diabetes mellitus requiring insulin therapy in two patients. Fatal pulmonary toxicity is a major concern of a quick course NAC-VBP. In conclusion, these patients require special monitoring for bleomycin-induced pulmonary toxicity.

Comparison of NeQuick, PIM, and TSM model results for the topside ionospheric plasma scale and transition heights  

NASA Astrophysics Data System (ADS)

The topside ionospheric scale height (Ts) and the O+ H+ transition height (Th) are key ionospheric characteristics that are of special interest when studying and modelling the plasma composition and dynamics. Recently, a new Topside Sounder Model (TSM) has been developed which provides the Ts and Th quantities together with the ratio between them, Ts/Th. The database for this model has been built upon thousands of Ts and Th values deduced from electron density profiles retrieved from topside sounding measurements. For validation purposes, it would be interesting to compare calculations of the ionospheric scale/transition heights from TSM with corresponding calculations from two other well-known models the NeQuick Model (NeQ) and the Parameterized Ionospheric Model (PIM). For the purpose, electron density profiles have been computed with both the NeQuick and PIM models over suitable grids of input parameters such as month, local time, geomagnetic latitude, solar activity, and in the altitude range between 200 and 2000 km. The topside ionospheric scale height and the O+ H+ transition height values have been extracted from each profile in the same manner as previously done for the TSM development database. Finally, the Ts and Th values deduced from the NeQuick and PIM profiles have been compared with the respective values provided by the TSM. Results of this comparison are analysed and suggestions are put forward for further improving the models in question. TSM applications are discussed as well.

A Race for Survival: Can Bromus tectorum Seeds Escape Pyrenophora semeniperda-caused Mortality by Germinating Quickly?  

PubMed Central

Background and Aims Pathogen–seed interactions may involve a race for seed resources, so that seeds that germinate more quickly, mobilizing reserves, will be more likely to escape seed death than slow-germinating seeds. This race-for-survival hypothesis was tested for the North American seed pathogen Pyrenophora semeniperda on seeds of the annual grass Bromus tectorum, an invasive plant in North America. In this species, the seed germination rate varies as a function of dormancy status; dormant seeds germinate slowly if at all, whereas non-dormant seeds germinate quickly. Methods Three experimental approaches were utilized: (a) artificial inoculations of mature seeds that varied in primary dormancy status and wounding treatment; (b) naturally inoculated undispersed seeds that varied in primary dormancy status; and (c) naturally inoculated seeds from the carry-over seed bank that varied in degree of secondary dormancy, habitat of origin and seed age. Key Results In all three approaches, seeds that germinated slowly were usually killed by the pathogen, whereas seeds that germinated quickly frequently escaped. Pyrenophora semeniperda reduced B. tectorum seed banks. Populations in drier habitats sustained 50 times more seed mortality than a population in a mesic habitat. Older carry-over seeds experienced 30 % more mortality than younger seeds. Conclusions Given the dramatic levels of seed death and the ability of this pathogen to reduce seed carry-over, it is intriguing to consider whether P. semeniperda could be used to control B. tectorum through direct reduction of its seed bank.

Quick Look Report for Chemical Reactivity Modeling of Various Multi-Canister Overpack Breaches  

SciTech Connect

This report makes observations or shows trends in the response and does not specifically provide conclusions or predict the onset of bulk uranium oxidation safety margins based on hole size. Comprehensive analysis will be provided in the future. The report should animate discussions about the results and what should be analyzed further in the final analysis. This report intends only to show the response of the breached multi-canister overpack (MCO) as a function of event time using the GOTH_SNF computer code. The response will be limited to physical quantities available on the exterior of the MCO. The GOTH_SNF model is approximate, because not all physical phenomenon was included in the model. Error estimates in the response are not possible at this time, because errors in the actual physical data are not known. Sensitivities in the results from variations in the physical data have not been pursued at this time, either. This effort was undertaken by the National Spent Nuclear Fuel Program to evaluate potential chemical reactivity issues of a degraded uranium metal spent nuclear fuel using the MCO fully loaded with Mark IV N-reactor fuel as the evaluation model. This configuration is proposed for handling in the Yucca Mountain Project (YMP) surface facility. Hanford is loading N-reactor fuel elements into the MCO for interim storage at the Hanford site with permanent disposal proposed at YMP. A portion of the N-reactor fuel inventory has suffered corrosion, exposing the uranium metal under the zircaloy cladding. Because of the sealed MCO, the local radiation field, and decay heat of the fuel, hydrogen production cannot be ruled out from the metal hydrates on the surface of the zircaloy cladding and exposed fuel. Because of the much greater surface area, the oxyhydroxide composition, and water of hydration in the uranium metal corrosion product, the corrosion product will be a significant water source that may equal the absorbed water on the zircaloy cladding. A uranium oxide coating covers the exposed uranium metal, yet uranium hydride can still form under the protective oxide coating over the 40-year interim storage time span. The current treatment process at Hanford does not remove chemically bound water contained in the hydrates or in the waters of hydration. The chemically bound water is the source material for hydrogen production over the 40-year storage time. So, additional uranium hydride creates concerns that breaches of an MCO with the appropriate size openings could result in the onset of bulk uranium oxidation with the potential of a self-sustaining thermal excursion or pyrophoric event. For this analysis, the worst-case scenario appears to be the match head configuration in a vertically standing MCO, where all the reactive surface area is placed on the tips of the fuel elements. This configuration concentrates the heat-producing chemical reaction at the tips of the fuel elements. Because no mechanistic drop analysis has been performed at this time to determine the MCO failure modes, parametric breach configurations were chosen in this analysis to determine the MCOs’ external thermal response range. The first breach is a pair of holes that suddenly open in the MCO wall. This thermal excursion is controlled by the “thermal chimney effect” in the 4.27-m (14-ft) tall canisters caused by the multiple holes breach (one high and one low). A second breach where the MCO lid is suddenly removed and exposed to the ambient air

Mapping giant reed with QuickBird imagery in the Mexican portion of the Rio Grande Basin  

NASA Astrophysics Data System (ADS)

Giant reed (Arundo donax L.) is a perennial invasive weed that presents a severe threat to agroecosystems and riparian areas in the Texas and Mexican portions of the Rio Grande Basin. The objective of this study was to use QuickBird satellite imagery to map giant reed infestations and estimate infested areas in the Mexican portion of the Rio Grande Basin (MPRGB). Intensive ground surveys were conducted and global positioning system (GPS) points were collected to document the locations along major tributaries and other infested areas in the MPRGB. To map the scattered infestations, QuickBird image scenes covering a total area of 7190 square km are needed. In this study, 40 archived and newly-tasked QuickBird image scenes acquired from 2002 to 2007 and covering a total area of 3252 square km were used. These images were classified using a maximum likelihood classifier and the areas for giant reed and water in each scene were determined. The total giant reed-infested area determined from the 40 images was 2160 ha. Since the 40 images constituted about 45.2% of the total area to be imaged, the total infested area in the MPRGB was estimated to be 4775 ha. Based on the images acquired along the tributaries, the ratio of giant reed-infested area to water area was 1.6 ha/ha and the ratio of giant reed-infested area to river length was 4.6 ha/km. Although actual infested areas are larger than the estimated areas because some of the infested areas may have not been counted during the ground surveys, this study provides the first and accurate estimates of giant reed infestations in the MPRGB. These results will be useful for both land owners and government agencies for the management and control of this invasive weed.

The protective effect of rapid cold-hardening develops more quickly in frozen versus supercooled larvae of the Antarctic midge, Belgica antarctica.  

PubMed

During the austral summer, larvae of the terrestrial midge Belgica antarctica (Diptera: Chironomidae) experience highly variable and often unpredictable thermal conditions. In addition to remaining freeze tolerant year-round, larvae are capable of swiftly increasing their cold tolerance through the rapid cold-hardening (RCH) response. The present study compared the induction of RCH in frozen versus supercooled larvae. At the same induction temperature, RCH occurred more rapidly and conferred a greater level of cryoprotection in frozen versus supercooled larvae. Furthermore, RCH in frozen larvae could be induced at temperatures as low as -12°C, which is the lowest temperature reported to induce RCH. Remarkably, as little as 15 min at -5°C significantly enhanced larval cold tolerance. Not only is protection from RCH acquired swiftly, but it is also quickly lost after thawing for 2 h at 2°C. Because the primary difference between frozen and supercooled larvae is cellular dehydration caused by freeze concentration of body fluids, we also compared the effects of acclimation in dehydrated versus frozen larvae. Because slow dehydration without chilling significantly increased larval survival to a subsequent cold exposure, we hypothesize that cellular dehydration caused by freeze concentration promotes the rapid acquisition of cold tolerance in frozen larvae.

Comparison of quick and slow thaw methods of producing cryoprecipitate antihaemophilic factor from fresh and 24-hour-old blood  

PubMed Central

Cryoprecipitate antihaemophilic factor concentrate was prepared from fresh and 24-hour-old blood by quick and slow thaw methods. Recovery of factor VIII was greater by the slow thaw method and there was less loss into the supernatant plasma. Cryoprecipitate produced from fresh blood contained more factor VIII than that produced from 24-hour-old blood so that the most potent concentrate was produced from fresh blood by the slow thaw process. An adequate therapeutic preparation was, however, produced by the slow thaw method using 24-hour-old blood and it is suggested that this procedure could be adopted in order to supplement supplies.

Growing up too quickly: Children who lose out on their childhoods  

PubMed Central

Despite the almost universal ratification of the Convention on the Rights of the Child, summits and conferences organized by international and local agencies, the awareness campaigns and the immense work performed by nongovernmental organizations, too many children continue to endure hardship. It is estimated that 8.4 million children are involved in the worst forms of child labour, namely labour that involves forced or bonded labour, sexual exploitation, illicit work and armed conflicts. The impact of such activities on the survival, health (both physical and mental) and development of children is devastating. Girls are particularly vulnerable. But children are resilient, and although longitudinal data on the validity of the programmes are not yet available, rehabilitation programs adapted to their own culture and reinsertion in their communities have shown positive results. Along with monitoring, research, education and rehabilitation, paediatricians have the responsibility, as physicians and advocates for children, to promote the respect of children’s rights while, at the same time, searching for solutions to eradicate poverty and prevent war. There should be zero tolerance for those who violate children’s rights.

Quick extended x-ray absorption fine structure instrument with millisecond time scale, optimized for in situ applications  

NASA Astrophysics Data System (ADS)

In order to learn about in situ structural changes in materials at subseconds time scale, we have further refined the techniques of quick extended x-ray absorption fine structure (QEXAFS) and quick x-ray absorption near edge structure (XANES) spectroscopies at beamline X18B at the National Synchrotron Light Source. The channel cut Si (111) monochromator oscillation is driven through a tangential arm at 5 Hz, using a cam, dc motor, pulley, and belt system. The rubber belt between the motor and the cam damps the mechanical noise. EXAFS scan taken in 100 ms is comparable to standard data. The angle and the angular range of the monochromator can be changed to collect a full EXAFS or XANES spectrum in the energy range 4.7-40.0 KeV. The data are recorded in ascending and descending order of energy, on the fly, without any loss of beam time. The QEXAFS mechanical system is outside the vacuum system, and therefore changing the mode of operation from conventional to QEXAFS takes only a few minutes. This instrument allows the acquisition of time resolved data in a variety of systems relevant to electrochemical, photochemical, catalytic, materials, and environmental sciences.

Quick magnetic reconnection triggering in an ion-scale current sheet: Transition from Type-I to Type-II  

NASA Astrophysics Data System (ADS)

The details of Quick Magnetic Reconnection Triggering (QMRT) in ion-scale current sheets have been investigated using three-dimensional (3-D) full particle simulations with the mass ratio of 400. QMRT is mediated by coupling to the Lower-Hybrid Drift Instability (LHDI) and its time scale is as quick as the LHDI time scale. Up to the initial half-thickness D of D/?i = 0.875 (?i: the ion inertial length), QMRT is attained via thin current layer formation at the center of the current sheet in reaction to the LHDI activity (Type-I). At D/?i = 1, QMRT is still available but is attained by boosting up the tearing instability growth rate via the electron temperature anisotropy Te$\\perp$/Te$\\parallel$ ~ 1.2 (Type-II). In this case the LHDI activity induces the current density redistribution that does not result in enhanced current density at the center but produces electron perpendicular heating therein.

Quick change of ion species of heavy-ion microbeam by cocktail beam acceleration technique with the JAEA AVF cyclotron  

NASA Astrophysics Data System (ADS)

A heavy-ion microbeam with hundreds of MeV energy is utilized for research in biotechnology and materials science at the JAEA AVF cyclotron facility. Beam users need microbeams providing a wide range of the LET. We have to change ion species and/or energy in order to vary the LET widely. However, it takes much time to develop a new microbeam of different ion species step by step using a flat-top acceleration system. A cocktail beam acceleration technique is frequently used to change the ion species and energy quickly. The cocktail beam acceleration has been first applied to the microbeam formation for quick change of the ion species. As a result, we have succeeded to reduce considerably microbeam changing time to within 30 min between a 520 MeV 40Ar14+ and a 260 MeV 20Ne7+. No deterioration of the microbeam spot size has been confirmed using a SE image of a copper grid.
