  1. FCC-ee: Energy Calibration

    SciTech Connect

    Koratzinos, M.; Blondel, A.; Gianfelice-Wendt, E.; Zimmermann, F.

    2015-06-02

    The FCC-ee aims to improve on electroweak precision measurements, with goals of 100 ke V on the Z mass and width, and a fraction of MeV on the W mass. Compared to LEP, this implies a much improved knowledge of the center-of-mass energy when operating at the Z peak and WW threshold. This can be achieved by making systematic use of resonant depolarization. A number of issues have been identified, due in particular to the long polarization times. However the smaller emittance and energy spread of FCC-ee with respect to LEP should help achieve a much improved performance.

  20. Case for an EeV Gravitino

    NASA Astrophysics Data System (ADS)

    Dudas, Emilian; Mambrini, Yann; Olive, Keith A.

    2017-08-01

    We consider the possibility that supersymmetry is broken above the inflationary mass scale and that the only "low" energy remnant of supersymmetry is the gravitino with a mass of the order of the EeV scale. The gravitino in this class of models becomes a candidate for the dark matter of the Universe. To avoid the overproduction of gravitinos from the decays of the next-to-lightest supersymmetric particle we argue that the supersymmetric spectrum must lie above the inflationary mass scale (MSUSY>10-5MP˜1 013 GeV ). Since m3 /2≃MSUSY2/MP , we expect m3 /2≳0.2 EeV . Cosmological constraints then predict a relatively large reheating temperature between 1 010 and 1 012 GeV .

  1. EE Cep observations requested for upcoming eclipse

    NASA Astrophysics Data System (ADS)

    Waagen, Elizabeth O.

    2014-07-01

    The AAVSO requests observations for the upcoming eclipse of EE Cephei, a long-period eclipsing variable. EE Cep has a period of 2,050 days, and shows strong variations in the eclipse light curve from one event to the next. Observations are needed to study the morphology of the upcoming eclipse, which will be used to better understand the shape of the eclipsing disk and how it precesses. Mid-eclipse is predicted to be August 23, 2014, but the early stages of the eclipse may begin as much as a month earlier. EE Cep is being observed by a number of amateur and professional astronomers using multiple telescopes at multiple wavelengths. Among these is a collaboration (see https://sites.google.com/site/eecep2014campaign/) headed by Cezary Galan at the Nicolaus Copernicus Astronomical Center in Poland; several individual AAVSO observers are already participating in this effort. The AAVSO is not currently a partner in that campaign, but all data submitted to the AAVSO will be publicly available. The AAVSO strongly encourages observers to begin following this star now, and to continue observations into October 2014 at least. Finder charts with sequence may be created using the AAVSO Variable Star Plotter (http://www.aavso.org/vsp). Observations should be submitted to the AAVSO International Database. See full Alert Notice for more details and observations.

  2. EE Cep Winks in Full Color (Abstract)

    NASA Astrophysics Data System (ADS)

    Walker, G.

    2015-06-01

    (Abstract only) We observe the long period (5.6 years) Eclipsing Binary Variable Star EE Cep during its 2014 eclipse. It was observed on every clear night from the Maria Mitchell Observatory as well as remote sites for a total of 25 nights. Each night consisted of a detailed time series in BVRI looking for short term variations for a total of >10,000 observations. The data was transformed to the Standard System. In addition, a time series was captured during the night of the eclipse. This data provides an alternate method to determine Time of Minimum than traditionally performed. The TOM varied with color. Several strong correlations are seen between colors substantiating the detection of variations on a time scale of hours. The long term light curve shows five interesting and different Phases with different characteristics.

  7. High Energy Polarized e+e- Beams

    NASA Astrophysics Data System (ADS)

    Shatunov, Yu.; Koop, I.; Otboev, A.; Mane, S.

    2016-02-01

    Recently, the wide discussion about Higgs-factory design again returns to problem of high energy polarized electrons and positrons. It’s good known the radiative beam polarization at LEP-collider. It was obtained after spin resonance suppression at Z0 pick, but didn’t appear at energies above 70 GeV due to an enhancement of unavoidable depolarization effects. We examine in this paper various ideas for radiative polarization at TLEP/FCC-ee and formulate some estimates for the polarization buildup time and the asymptotic polarization. Using wigglers, a useful degree of polarization (for energy calibration), with a time constant of about 1 h, may be possible up to the threshold of W pair production. At higher energies such as the threshold of Higgs production, attaining a useful level of polarization may be difficult in a planar ring. With Siberian Snakes, wigglers and some imagination, polarization of reasonable magnitude, with a reasonable time constant (of not more than about 1 h), may be achievable at very high energies.

  8. Micro-canonical pentaquark production in ee and pp collisions

    NASA Astrophysics Data System (ADS)

    Liu, Fu-Ming; Werner, Klaus

    2008-01-01

    The existence of pentaquarks became questionable, because the Θ peak is observed in some p+p collisions, but not in ee annihilations. People think initial baryon number is necessary to produce pentaquarks. In this paper, we estimate and compare the production of Θ(1540) and Ξ(1860) in ee and pp collisions at different energies using Fermi statistical model as originally proposed in its microcanonical form. We find that both Θ(1540) and Ξ(1860) yield more in ee at LEP energies than in pp collisions at SPS and RHIC energies, if pentaquarks do exist. Initial baryon number is not necessary for pentaquark production.

    2017-06-01

    The technique of discrimination of the e+e- → e+e- and e+e- → π+π- events in energy range 0.5 < √s < 1 GeV based on the difference in the energy deposition in calorimeter of SND detector was developed by applying machine learning method. Identification efficiency for e+e- → e+e- and e+e- → π+π- events is estimated to be in the range from 99.3 to 99.8%. Contribution of the identification efficiencies errors to the total error of e+e- → π+π- cross section is less than 0.2% for the most energy points.

  20. Proposed Injection into “Thief” Zone in EE-3

    Potter, Robert M.; Grigsby, Charles O.

    1983-08-18

    This report seeks to understand the nature of the "thief" zone inside the EE-3 by pumping 150-200K gallons of heated water into that zone. The questions they seek to answer are; does the thief zone represent a potential danger to future operations in the form of earthquakes, aquifers, damage to equipment or tubulars, or require that it be sealed; is a connection into the the thief zone from EE-2 a disaster point; could the connection into the thief zone provide a low back-pressure condition.

  1. Expressed emotion, human agency, and schizophrenia: toward a new model for the EE-relapse association.

    2009-03-01

    Although there is a clear statistical association between expressed emotion (EE) and schizophrenic relapse, our understanding of the mechanisms underlying this relationship is underdeveloped. This study tested a theoretical model in which caregivers' perceptions of their ill relative's agency underlie the EE-relapse association. To evaluate this model, we completed qualitative and quantitative analyses of narratives provided by individuals caring for a relative with schizophrenia. The results indicate that high-EE caregivers perceive the expression of symptoms as stemming from their ill relative's agency more frequently than low-EE caregivers. This was true for both high-EE-criticism and high-EE-emotional overinvolvement caregivers. High-EE and low-EE caregivers did not differ in their perceptions of the role of their ill relative's agency with regard to the control of symptoms. The findings suggest that EE may be a proxy risk factor for caregivers' perceptions of their ill relative's agency.

    Laryngopharyngeal reflux (LPR) is defined as the retrograde flow of gastric contents up through the esophagus to the larynx and hypopharynx; this is an extra-esophageal manifestation of gastroesophageal reflux disease (GERD). Although both LPR and GERD are caused by reflux of stomach contents, their clinical presentations and treatments differ. In the present study, we assessed esophago-gastroendoscopic findings related to GERD, specifically endoscopic-positive esophagitis (EE), laryngopharyngeal findings, and GERD symptoms on the 12-question frequency scale for the symptoms of gastroesophageal reflux disease (FSSG). Then, independent predictors of EE were analyzed, and relationships among EE, laryngopharyngeal findings, and patients' symptoms and characteristics were investigated. Hiatal hernia (odds ratio [OR]: 2.70; 95% confidence interval [CI]: 1.17-6.23, P-value 0.019) and edema of theinterarytenoid mucosa (OR, 3.77; 95% CI, 1.26-16.3; P-value 0.035) were significantly related with EE and independent predictors of EE. However, patients' characteristics and the FSSG score had no significant relationship with EE; there was no relationship between patients' characteristics and EE, regardless of its severity. Although LPR symptoms had no significant relationship with the findings of EE, hiatal hernia and edema of the interarytenoid mucosa were significantly related with EE and were considered to be independent predictors of EE. © 2013 The Authors.

    Using the data sets taken at center-of-mass energies above 4 GeV by the BESIII detector at the BEPCII storage ring, we search for the reaction e+e- →γISR X (3872) →γISRπ+π- J / ψ via the Initial State Radiation technique. The production of a resonance with quantum numbers JPC =1++ such as the X (3872) via single photon e+e- annihilation is forbidden, but is allowed by a next-to-leading order box diagram. We do not observe a significant signal of X (3872), and therefore give an upper limit for the electronic width times the branching fraction ΓeeX (3872) B (X (3872) →π+π- J / ψ) < 0.13 eV at the 90% confidence level. This measurement improves upon existing limits by a factor of 46. Using the same final state, we also measure the electronic width of the ψ (3686) to be Γeeψ (3686) = 2213 ±18stat ±99sys eV.

    Eating in response to negative emotions is associated with binge or loss of control (LOC) eating in adults. Although children report engaging in LOC eating, data on emotional eating among youth are limited. We adapted the adult Emotional Eating Scale (Arnow et al., Int J Eat Disord, 18, 79-90, 1995) to be used with children and adolescents (EES-C). Fifty-nine overweight (BMI > or = 95th percentile for age and sex) and 100 non-overweight (BMI 5th-94th percentile) participants (mean age +/- SD 14.3 +/- 2.4 years) completed the EES-C, and measures of recent LOC eating and general psychopathology. Test-retest reliability was assessed in 64 children over a 3.4 +/- 2.6 month interval. A factor analysis generated three subscales: eating in response to anxiety, anger, and frustration (EES-C-AAF), depressive symptoms (EES-C-DEP), and feeling unsettled (EES-C-UNS). Internal consistency for the subscales was established; Cronbach's alphas for the EES-C-AAF, EES-C-DEP, and EES-C-UNS were 0.95, 0.92, and 0.83, respectively. The EES-C had good convergent validity: children reporting recent LOC eating episodes scored higher on all subscales (p's < 0.05). The EES-C-AAF and EES-C-UNS subscales demonstrated good discriminant validity and the EES-C-DEP revealed adequate discriminant validity. Intra-class correlation coefficients revealed good temporal stability for each subscale (EES-C-AAF = 0.59, EES-C-DEP = 0.74, EES-C-UNS = 0.66; p's < 0.001). The EES-C has good convergent and discriminant validity, and test-retest reliability for assessing emotional eating in children. Further investigation is required to clarify the role emotional eating may play in children's energy intake and body weight.

    This study was undertaken to determine the fetal E/e or e/e Rh genotype prenatally from peripheral maternal blood by examining sorted fetal cells from alloimmunized and nonalloimmunized pregnancies. Eighteen maternal peripheral venous blood samples were obtained before amniocentesis from 15 pregnant women who were homozygous for the e allele. Five were not alloimmunized and 10 were alloimmunized. The mononuclear cell layer was isolated from the maternal blood and enriched for fetal nucleated red blood cells by flow cytometry with monoclonal antibodies to CD36 or CD71 and to glycophorin A. Eight samples were treated with CD45 monoclonal antibody-coated magnetic beads before they were sorted to deplete the maternal sample of leukocytes (CD45(+) cells). We defined the positive fetal cell fractions as the monoclonal antibody positive-sorted cells derived from the maternal samples. These included sorted cells that were CD36(+)/glycophorin A(+), CD71(+)/glycophorin A(+) and CD45(-) cells that were sorted to become CD45(-)/CD36(+)/glycophorin A(+) or CD45(-)/CD71(+)/glycophorin A(+). The negative fractions were the cells that were negative for either CD36/glycophorin A or CD71/glycophorin A or were the CD45(+) cells. Deoxyribonucleic acid was isolated from all fractions and amplified by polymerase chain reaction with allele-specific primers for the E or e Rh genes. Gel electrophoresis was performed to detect fetal E/e or e/e Rh genotype. The fetal E/e or e/e Rh genotype was confirmed by serologic and deoxyribonucleic acid testing. The accuracy of E/e or e/e Rh genotype determination from the positive cell fractions was compared with that of E/e or e/e Rh genotype determination from the negative fractions. Fetal E/e or e/e Rh genotype was determined correctly in 17 of 18 of the fetal cell enriched positive fractions (94%). Fetal E/e or e/e Rh genotype was determined correctly in 11 of 14 of the maternal samples in the negative unselected cell fractions (79%). Fetal E/e or

    EE process produces single-crystalline Silicon nanowires with rough walls. We use suspended structures to directly compute the heat transfer through single nanowires. Nanowires with diameters less than the mean free path of phonons impede transport by boundary scattering. The roughness acts as a secondary scattering mechanism to further reduce phonon transport. By controlling the amount of roughness it is possible to push limits to the extent that nanowire conductance close to quanta of thermal conductance,πkB^2 T / πkB^2 T 6 . - 6 is observed. Traditionally, the lower limit of conductivity is amorphous Silicon at 1 W/mK at room temperature. The measured conductivity of our nanostructures challenges even this amorphous limit pointing towards previously unstudied mechanisms of thermal resistance. We measure thermal conductivity of ˜150nm diameter EE wires to be ˜1 W/mK.

  5. EE-3A Logging Report for Feb. 28th., 1994

    SciTech Connect

    Anderson, David W.

    1994-03-14

    A Temperature/Casing-Collar Locator (CCL) log of EE-3A was performed on Monday, February 28th, 1994. This log was the first of two, (the other to be run on March 31st.), in an attempt to investigate a temperature anomaly occurring between 10,000 to 11,435 ft. The thermal recovery of this zone is slower than expected, which is believed to be caused by either; flow through the cemented zone of the 5 1/2" liner, or an upward flow through the reservoir itself. Now that the first log is over, the annulus of EE-3A will be shut-in for a period of approximately one month, at which time the log will be repeated. If the temperature of this zone shows signs of recovery after the shut-in period, the integrity of the cement will be in question. No sign of recovery will point to upward reservoir flow theory.

    Based on a sample of η' mesons produced in the radiative decay J /ψ →γ η' in 1.31 ×109 J /ψ events collected with the BESIII detector, the decay η'→ω e+e- is observed for the first time, with a statistical significance of 8 σ . The branching fraction is measured to be B (η'→ω e+e-)=(1.97 ±0.34 (stat)±0.17 (syst))×10-4 , which is in agreement with theoretical predictions. The branching fraction of η'→ω γ is also measured to be (2.55 ±0.03 (stat)±0.16 (syst))×10-2 , which is the most precise measurement to date, and the relative branching fraction B/(η'→ω e+e-) B (η'→ω γ ) is determined to be (7.71 ±1.34 (stat)±0.54 (syst))×10-3 .

    One of the interesting portals linking a dark sector and the Standard Model (SM) is the kinetic mixing between the SM U(1)Y field with a new dark photon A‧ from a U(1)A‧ gauge interaction. Stringent limits have been obtained for the kinetic mixing parameter 𝜖 through various processes. In this work, we study the possibility of searching for a dark photon interaction at a circular e+e- collider through the process e+e-→ γA‧→ γμ+μ-. We find that the constraint on 𝜖2 for dark photon mass in the few tens of GeV range, assuming that the μ+μ- invariant mass can be measured to an accuracy of 0.5% mA‧, can be better than 3 × 10-6 for the proposed CEPC with a 10-year running at 3σ (statistic) level, and better than 2 × 10-6 for FCC-ee with even just one-year running at s = 240GeV, better than the LHCb, ATLAS, CMS experiments and other facilities can do in a similar dark photon mass range. For FCC-ee, running at s = 160GeV, the constraint can be even better.

    To determine if EE/CA and EE/CA plus metformin treatment have any effect on adhesion molecules in cases with PCOS. Among 40 patients diagnosed with PCOS, one study arm was administered EE/CA (n=20, cyproterone acetate 2 mg, ethinylestradiol 35 microg) and the other was administered metformin (1,700 mg) combined with EE/CA (n=20, cyproterone acetate 2 mg, ethinylestradiol 35 microg). Soluble intercellular adhesion molecule-1 (sICAM-1), soluble endothelial leukocyte adhesion molecule-1 (sE-selectin), soluble vascular cell adhesion molecule-1 (sVCAM-1), soluble leukocyte endothelial cell adhesion molecule-3 (sP-selectin), lipid profile, androgens, insulin, and HOMA-IR values were assessed prior to treatment and after 3 months of therapy. The comparison of the groups receiving EE/CA and EE/CA+metformin revealed a significant reduction in sVCAM (1,445+/-614 vs 1,167+/-482, p<0.05) and sICAM (442+/-141 vs 345+/-118, p<0.05) values relative to pre-treatment values while no significant changes were detected in sE-selectin and sP-selectin levels relative to pre-treatment levels in the EE/CA+metformin group (p>0.05). In the post-treatment period, sVCAM, sICAM, sE-selectin values did not significantly change compared to the pre-treatment values in EE/CA group (p>0.05). sP-selectin levels were also decreased but missed the significance in EE/CA group (229.4+/-68.0 vs 189.6+/-65.0, p=0.08). These results demonstrate that EE/CA+metformin treatment reduced inflammation markers in cases with PCOS compared to EE/CA treatment. The clinical relevance of this conclusion may be clarified by longer metformin treatment and clinical follow-up.

  3. Constraints on axions from π0 --> e+e- decay

    NASA Astrophysics Data System (ADS)

    Massó, Eduard

    1986-12-01

    The contribution of axions to π0 --> e+e- decay is considered. It is found that a recently proposed short-lived axion with a mass of 1.8 MeV induces a decay rate inconsistent with experimental observations. More generally, upper limits are placed on the mass of an axion that couples to first-generations fermions.

    We apply the "jet calculus" of Konishi, Ukawa, and Veneziano (KUV) to the two-particle spectra of e+e- jets. This computation uses single-particle fragmentation functions and the KUV analysis of leading logarithms to predict the multiparticle spectra entirely from the single-particle data. The effects of charm and heavier flavors are discussed and a simple prescription for inverting the necessary double moments is given. The double-differential cross section dσdx1dx2 is displayed for various combinations of mesons and the antiproton.

    During Experiment 2042 approximately 2 million gallons of water were injected in the EE-3 wellbore. This caused seismic activity from the bottom of the well to a region well above the casing shoe (3900 m TVD to 2800 m TVD). Thus water was injected into both the lower high pressure zone and the upper low pressure zone just below the casing shoe. Later experiments have shown that these two zones are connected. In the past the upper zone has often been considered to be a water loss zone (thief zone).

    Direct photon production in hadronic events from e+e- annihilation has been studied at √s =29 GeV with use of the MAC detector at the PEP storage ring. A charge asymmetry A=(-12.3+/-3.5)% is observed in the final-state jets. The cross section and the charge asymmetry are in good agreement with the predictions of the fractionally charged quark-parton model. Both the charge asymmetry and total yield have been used to determine values of quark charges. Limits have been established for anomalous sources of direct photons.

    The masses and signals of the production of doubly charged Higgses (DCH) in the framework of the supersymmetric reduced minimal 3-3-1 model are investigated. In the DCH sector, we prove that there always exists a region of the parameter space where the mass of the lightest DCH is of the order of O(100) GeV even when all other new particles are very heavy. The lightest DCH mainly decays to two same-sign leptons while the dominant decay channels of the heavy DCHs are those decaying to heavy particles. We analyze each production cross section for e^+e^- ⇒ H^{++} H^{-} as a function of a few kinematic variables, which are useful to discuss the creation of DCHs in e^+e^- colliders as an indicator of new physics beyond the Standard Model. A numerical study shows that the cross sections for creating the lightest DCH can reach values of a few pb. The other two DCHs are too heavy, beyond the observable range of experiments. The lightest DCH may be detected by the International Linear Collider or the Compact Linear Collider by searching for its decay to a same-sign charged lepton pair.

    Measurements of air showers made using the hybrid technique developed with the fluorescence and surface detectors of the Pierre Auger Observatory allow a sensitive search for point sources of EeV photons anywhere in the exposed sky. A multivariate analysis reduces the background of hadronic cosmic rays. The search is sensitive to a declination band from -85° to +20°, in an energy range from 1017.3 eV to 1018.5 eV. No photon point source has been detected. An upper limit on the photon flux has been derived for every direction. The mean value of the energy flux limit that results from this, assuming a photon spectral index of -2, is 0.06 eV cm-2 s-1, and no celestial direction exceeds 0.25 eV cm-2 s-1. These upper limits constrain scenarios in which EeV cosmic ray protons are emitted by non-transient sources in the Galaxy.

    Preparative chemical methods for the synthesis of 10 degradation or photodecomposition products of mestranol and ethinyl estradiol (EE) are described. The synthesized compounds are useful as reference materials and standards for pharmaceutical analysis of mestranol and EE as bulk chemical or in formulated product. New synthetic methods were presented and the known synthetic procedures were improved. Detailed structural characterization of the degradation or photodecomposition products of mestranol and EE and related compounds was reported.

  11. Double Higgs Boson Production via WW Fusion in TeV e+e- Collisions

    Barger, V.; Han, T.

    The production of two standard model Higgs bosons via the WW fusion process e+e- → bar ve ve HH would test the predicted HHH, HWW and HHWW couplings. At TeV energies this fusion cross section dominates over that from e+e- →ZHH and would give significant event rates for mH ≲ 1/2 MZ at high luminosity e+e- colliders. We evaluate the rates and present the dynamical distributions.

    Objective Eating in response to negative emotions is associated with binge or loss of control (LOC) eating in adults. Although children report engaging in LOC eating, data on emotional eating among youth are limited. Method We adapted the adult Emotional Eating Scale (Arnow et al., Int J Eat Disord, 18, 79–90, 1995) to be used with children and adolescents (EES-C). Fifty-nine overweight (BMI ≥ 95th percentile for age and sex) and 100 non-overweight (BMI 5th–94th percentile) participants (mean age ± SD 14.3 ± 2.4 years) completed the EES-C, and measures of recent LOC eating and general psychopathology. Test-retest reliability was assessed in 64 children over a 3.4 ± 2.6 month interval. Results A factor analysis generated three subscales: eating in response to anxiety, anger, and frustration (EES-C-AAF), depressive symptoms (EES-C-DEP), and feeling unsettled (EES-C-UNS). Internal consistency for the subscales was established; Cronbach’s alphas for the EES-C-AAF, EES-C-DEP, and EES-C-UNS were 0.95, 0.92, and 0.83, respectively. The EES-C had good convergent validity: children reporting recent LOC eating episodes scored higher on all subscales (p’s < 0.05). The EES-C-AAF and EES-CUNS subscales demonstrated good discriminant validity and the EES-C-DEP revealed adequate discriminant validity. Intra-class correlation coefficients revealed good temporal stability for each subscale (EES-C-AAF = 0.59, EES-C-DEP = 0.74, EES-C-UNS = 0.66; p’s < 0.001). Conclusion The EES-C has good convergent and discriminant validity, and test-retest reliability for assessing emotional eating in children. Further investigation is required to clarify the role emotional eating may play in children’s energy intake and body weight. PMID:17262813

    Previous attempts to connect Fenton Hill Hot Dry Rock Geothermal Site Wells EE-2 and EE-3 by pumping 150 thousand to 1.3 million gallons of water had not achieved a detectable hydraulic fracture connection. Therefore, preparations were made to conduct, in December 1983, a 4 to 6 million gallon, 50 BPM water injection in EE-2. The objective was to enlarge the previously created reservoir in EE-2 using massive hydraulic facturing (MHF). The planning, preparations, operations and results of the MHF are presented here. 4 refs., 7 figs.

    By late Thursday, 5-9-85, EE-3A should be at a depth of about 12,200 feet. We plan to stop drilling at this point and pressurize the bottom 600 to 700 feet of the open hole using a Lynes packer. The Lynes packer would be set somewhere in the interval of very competent, slow-drilling, and only slightly altered biotite granodiorite from 11,460 ft to 11,590 ft. This would place the packer below the two fractures (at 10,880 ft and 11,000 ft) stimulated during Expt. 2057, and also below the producing fracture at 11,440 ft as reported on 5-2-85.

    The recent data on the transverse single spin asymmetry A{sub UT}{sup sin({phi}{sub h}+{phi}{sub S})} from HERMES and COMPASS Collaborations are analysed within LO parton model with unintegrated parton distribution and fragmentation functions. A fit of SIDIS data from HERMES Collaboration is performed leading to the extraction of favoured and unfavoured Collins fragmentation functions. A very good description of COMPASS data is obtained. BELLE e+e- data are shown to be compatible with our estimates based on the extracted Collins fragmentation functions. Predictions for A{sub UT}{sup sin({phi}{sub h}+{phi}{sub S})} asymmetries at JLab and COMPASS operating on a proton target are given.

    A thorough search of the sky exposed at the Pierre Auger Cosmic Ray Observatory reveals no statistically significant excess of events in any small solid angle that would be indicative of a flux of neutral particles from a discrete source. The search covers from -90° to +15° in declination using four different energy ranges above 1 EeV (1018 eV). The method used in this search is more sensitive to neutrons than to photons. The upper limit on a neutron flux is derived for a dense grid of directions for each of the four energy ranges. These results constrain scenarios for the production of ultrahigh energy cosmic rays in the Galaxy.

    The design of a 100 km circular e + e - collider with extremely high luminosity is an important component of the global Future Circular Collider (FCC) study hosted by CERN. FCC-ee is being designed to serve as Z, W, H and top factory, covering beam energies from 45.6 to 175 GeV. For the injectors, the Z-operation is the most challenging mode, due to the high total charge and low equilibrium emittance in the collider at this energy. Thus, fulfilling the Z-mode will also meet the demands for all other modes of FCC-ee. This goal can be achieved by using a 6 GeV NC linac with an S-band RF frequency of 2.856 GHz and a repetition rate of 100 Hz. This linac will accelerate two bunches per RF pulse, each with a charge of 6.5 nC. Positrons will be generated by sending 4.46 GeV e - onto a hybrid target so that the e + created can still be accelerated to 1.54 GeV in the remaining part of the same linac. The emittance of the e + beam will then shrink to the nm level in a 1.54 GeV damping ring. After damping, the e + will be reinjected into the linac and accelerated to 6 GeV. The e - and e + will then be accelerated alternately to 45.6 GeV in the booster, before they are injected into the collider.

    Adequate folate supplementation in the periconceptional phase is recommended to reduce the risk of neural tube defects. Oral contraceptives may provide a reasonable delivery vehicle for folate supplementation before conception in women of childbearing potential. This study aimed to demonstrate that a fixed-dose combination of an oral contraceptive and levomefolate calcium leads to sustainable improvements in folate status compared with an oral contraceptive + folic acid. This was a double-blind, randomized, parallel-group study in which 172 healthy women aged 18-40 years received ethinylestradiol (EE)-drospirenone-levomefolate calcium or EE-drospirenone + folic acid for 24 weeks (invasion phase), and EE-drospirenone for an additional 20 weeks (folate elimination phase). The main objective of the invasion phase was to examine the area under the folate concentration time-curve for plasma and red blood cell (RBC) folate, while the main objective of the elimination phase was to determine the duration of time for which RBC folate concentration remained ≥ 906 nmol/L after cessation of EE-drospirenone-levomefolate calcium. Mean concentration-time curves for plasma folate, RBC folate, and homocysteine were comparable between treatment groups during both study phases. During the invasion phase, plasma and RBC folate concentrations increased and approached steady-state after about 8 weeks (plasma) or 24 weeks (RBC). After cessation of treatment with levomefolate calcium, folate concentrations decreased slowly. The median time to RBC folate concentrations falling below 906 nmol/L was 10 weeks (95% confidence interval 8-12 weeks) after cessation of EE-drospirenone-levomefolate calcium treatment. Plasma and RBC folate levels remained above baseline values in 41.3% and 89.3% of women, respectively, at the end of the 20-week elimination phase. Improvements in folate status were comparable between EE-drospirenone-levomefolate calcium and EE-drospirenone + folic acid. Plasma and

    From Nov. 25 to Dec. 1, 1985, 189,700 gallons of Fenton Hill well water were injected into EE-2 using the big Kobe pump (at 34 gpm). Temperature logs were run in EE-3A on Dec. 3 and 5 to assess the results of this reservoir reinflation.

  6. Redrilling of well EE-3 at the Los Alamos National Laboratory HDR (Hot Dry Rock) project

    The successful sidetracking of well EE-3 and the drilling of well EE-3A proved that with detailed planning and by adjusting techniques based on previous experience at Fenton Hill, drilling can be accomplished with reduced risk. The primary drilling problems associated with drilling of hot, crystalline basement rock, are (a) abrasiveness between the downhole tools and the formations and (b) a crooked wellbore path. These were essentially eliminated by a specially designed drilling fluid and careful pre-planning of the directional drilling operations. These improvements have taken much of the risk out of drilling at the Fenton Hill Hot Dry Rock (HDR) Geothermal Test Site. The sidetracking of EE-3 and drilling of EE-3A were undertaken to complete the hydraulic connection between boreholes. Drilling through fractured regions indicated by the dense zones of microseismic activity increased the probability of success. EE-3 was sidetracked at 9373' and redrilled to a depth of 13,182'.

    1983-03-15

    The purpose of Experiment 2018 was to achieve a hydraulic connection between EE-2 and EE-3 in the region just below their respective casing shoes. To protect the cassing of EE-2, the fracturing fluid had to be pumped down a 3-1/2 inch drill string to an Otis casing packer set 240 ft above the casing shoe of EE-2. Pumping started at 16:23 of July 19, 1982, and was terminated at 2:02 on July 20, 1982, due to hardware failure, after some trouble with the setting of the casing packer had delayed the beginning of the experiment for approximately two days. Prior to the experiment, a sand plug in EE-2 had been set, with its top at 11,910 ft (all depths referenced her are cable depths). A total of 5,698 bbls had been pumped. No hydraulic connection appeared at the end of Experiment 2018.

    Access control based on RBAC makes the system suitable to the security strategy for special application, relieves burden of system administrators and can adapt itself to the adjustment of the system structure flexibly. But all the existing security mechanisms of the middleware technology can't support the RBAC model very well. The method using J2EE security mechanisms to support RBAC is showed in this paper. First, the configuration of J2EE security systems is given in the paper and the algorithm of J2EE authorization decision is designed. Then, the language of J2EE security description is used to define RBAC, and realization of the requirement of J2EE security service is given. It has achieved the anticipative effect in virtue of deployment and application on the platform of the national science technology infrastructure.

  19. [Homozygous hemoglobin-E (Hb-EE) disease].

    PubMed

    Amendola, G; Danise, P; Di Palma, A; Franzese, M; Avino, D; D'Arco, A M

    2004-01-01

    The Authors report on a 16 year-old girl, of Cambodian descent, who was admitted to the hospital for hematuria. She showed a mild microcytic, hypochromic anemia with a normal iron balance; clinical examination was normal with neither pallor nor icterus nor splenomegaly; electrophoresis of hemoglobin yielded no hemoglobin A, a sligtly increased amount of HbF and a single band with a mobility similar to that of HbA2; the patient showed no evidence of overt increased hemolysis. With the DNA technology a final diagnosis of homozygous hemoglobin E was made. Hemoglobin E is the most common Hb variant among Southeast Asian populations. The Authors discuss on the benign nature of Hb-EE disease, pointing out that the presence of a single HbE gene in combination with that for beta-thalassemia leads generally to a disorder often comparable in severity to that of homozygous beta-thalassemia. With the recent migration of a high number of people from the countries, where HbE is extremely frequent, to the Western world (including Italy), this thalassemia syndrome is now a global health problem; therefore its knowledge is an important diagnostic challenge to all the experts involved in the care of thalassemic patients.

  20. Lower bound on e+e- decay of massive neutrinos

    NASA Technical Reports Server (NTRS)

    Cowsik, R.; Schramm, D. N.; Hoflicn, P

    1988-01-01

    Astronomical observations of SN1987A, such as the light curve, spectral intensities of lines, the X-ray emissions, etc., constrain the lifetime for the decay of a heavy neutrino 1 MeV less than or equivalent to m sub nu H less than or equal to 50 MeV through nu sub H yields nu sub 1+e(+)+e(-) exceeds 4 x 10 to the 15th exp(-m sub nuH/5MeV) seconds. Otherwise. resulting ionization energy deposits and stronger X-ray emission would have been observed. This coupled with traditional cosmological considerations argues that the lifetime of tau-neutrinos probably exceeds the age of the universe. This in turn would imply the standard cosmological mass bound does apply to nu sub tau, namely m sub nu sub tau less than or equivalent to 100 h squared eV (where h is the Hubble constant in units of 100 km/sec/mpc). The only significant loophole for these latter arguments would be if nu sub tau primarily decays rapidly into particles having very weak interactions.

    Alignment-free genome and metagenome comparisons are increasingly important with the development of next generation sequencing (NGS) technologies. Recently developed state-of-the-art k-mer based alignment-free dissimilarity measures including CVTree, $d_2^*$ and $d_2^S$ are more computationally expensive than measures based solely on the k-mer frequencies. Here, we report a standalone software, aCcelerated Alignment-FrEe sequence analysis (CAFE), for efficient calculation of 28 alignment-free dissimilarity measures. CAFE allows for both assembled genome sequences and unassembled NGS shotgun reads as input, and wraps the output in a standard PHYLIP format. In downstream analyses, CAFE can also be used to visualize the pairwise dissimilarity measures, including dendrograms, heatmap, principal coordinate analysis and network display. CAFE serves as a general k-mer based alignment-free analysis platform for studying the relationships among genomes and metagenomes, and is freely available at https://github.com/younglululu/CAFE. © The Author(s) 2017.

    Cosmic rays in the energy range 1018.0-1018.5 eV are thought to have a light, probably protonic, composition. To study their origin one can search for anisotropy in their arrival directions. Extragalactic cosmic rays should be isotropic, but galactic cosmic rays of this type should be seen mostly along the galactic plane, and there should be a shortage of events coming from directions near the galactic anticenter. This is due to the fact that, under the influence of the galactic magnetic field, the transition from ballistic to diffusive behavior is well advanced, and this qualitative picture persists over the whole energy range. Guided by models of the galactic magnetic field that indicate that the enhancement along the galactic plane should have a standard deviation of about 20° in galactic latitude, and the deficit in the galactic anticenter direction should have a standard deviation of about 50° in galactic longitude, we use the data of the Telescope Array surface detector in 1018.0 to 1018.5 eV energy range to search for these effects. The data are isotropic. Neither an enhancement along the galactic plane nor a deficit in the galactic anticenter direction is found. Using these data we place an upper limit on the fraction of EeV cosmic rays of galactic origin at 1.3% at 95% confidence level.

  3. Preferential acceleration and magnetic field enhancement in plasmas with e+/e- beam injection

    2016-03-01

    A theoretical model of current filaments predicting preferential acceleration/deceleration and magnetic field enhancement in a plasma with e+/e- beam injection is presented. When the e+/e- beams are injected into a plasma, current filaments are formed. The beam particles are accelerated or decelerated depending on the types of current filaments in which they are trapped. It is found that in the electron/ion ambient plasma, the e+ beam particles are preferentially accelerated, while the e- beam particles are preferentially decelerated. The preferential particle acceleration/deceleration is absent when the ambient plasma is the e+/e- plasma. We also find that the particle momentum decrease can explain the magnetic field increase during the development of Weibel/filamentation instability. Supporting simulation results of particle acceleration/deceleration and magnetic field enhancement are presented. Our findings can be applied to a wide range of astrophysical plasmas with the e+/e- beam injection.

    1982-01-01

    The deviated directional drilling of the hot dry rock (HDR) geothermal production well EE-3 (Energy Extraction No. 3) was successfully completed on August 1981. The injection well, EE-2, previously had been drilled with its lower part at an inclination of 35/sup 0/ to the vertical. It reached an on-line depth of 15,292 feet and its bottom-hole temperature was 608/sup 0/F (320/sup 0/C). The production well EE-3 was required to be drilled 1200 feet (370 m) above and parallel to the injection well. This necessitated high precision, controlled-trajectory directional drilling operations. The directional drilling of EE-3 was accomplished within the required tolerances at a depth of 13,933 feet and a bottom-hole temperature of 580/sup 0/F (280/sup 0/C).

  6. Environmental exposure assessment of ethinyl estradiol (EE) from a combined hormonal vaginal contraceptive ring after disposal; leaching from landfills.

    In this study an environmental exposure assessment and experiments were carried out to identify the leaching potential of ethinyl estradiol (EE) present in a vaginal contraceptive (NuvaRing) when disposed of in landfills. Landfill material and a sandy soil were used to investigate the mobility of EE. Log K(oc) values determined in the range of 3 to 4 indicate that EE does not have a high mobility in landfills and soils. Column experiments were used to estimate that it takes approximately 40 years before EE leaches from a column of 1 m of landfill material or sandy soil. This column experiment, which was performed with an EE concentration based on worst-case assumptions, demonstrates that the emission of EE from landfills is negligible. Sandy soils below landfills also act as a strong sorbent of EE, thereby further reducing the potential for groundwater contamination.

    The present work was carried out to study the ability of avian "Extract Egg" (EE) for reprogramming caprine fetal cells. The isolated caprine fetal cells were cultured in stem cell media supplemented with different percentages of either EE or FBS. The results indicated that the supplementation of 2-4% EE formed lesser but larger size stem cell like cell colonies as compared to 6% or 10% EE. The expression of pluripotent genes were comparatively higher in colonies developed in 2% or 4% as compared to 6% or 10% EE. Further, immunocytochemistry revealed that the colonies developed in all percentage of EE expressed pluripotent markers like Oct4, Nanog, TRA-1-60 and TRA-1-81. Our findings indicated that avian EE has the potentiality to reprogram caprine fetal cells into embryonic state which may help in generation of pluripotent stem cells without using viral vector.

    2013-02-01

    The level of expressed emotions in the family (EE) and components thereof (emotional over-involvement EOI, and critical comments CC) have been found to be related to treatment outcomes in psychotic patients. One point of interest is the dynamic of various outcomes in relation to initial EE, CC and EOI levels. 43 individuals with diagnosis of schizophrenia were assessed at 1, 3, 7, 12 and 20-year follow-ups. The EE indicator was evaluated during the index hospitalization. Outcome indicators included: number of relapses, number and duration of in-patient rehospitalizations, and severity of psychopathological symptoms. 1) A high EE indicator was associated with a higher number of relapses in every follow-up and differences between the groups with low and high EE indicators proved significant after 3, 7, 12 and 20 years of the illness. 2) A high EE indicator was associated with a higher number of rehospitalizations after 3 and 7 years, and showed as a clear trend after 12 and 20 years. 3) A high level of CC was associated with a higher number of relapses. 4) The severity of positive symptoms increased only in the group with high CC. 5) The negative syndrome was not associated with EE, EOI or CC. The EE indicator may be considered a valid prolonged predictor of relapses and rehospitalizations. A high level of CC was associated with a higher number of relapses and intensification of the positive syndrome in both the short-term and long-term course of the illness.

  20. Insulin-like growth factor 1 (IGF-1) mediates the effects of enriched environment (EE) on visual cortical development.

    PubMed

    Ciucci, Francesca; Putignano, Elena; Baroncelli, Laura; Landi, Silvia; Berardi, Nicoletta; Maffei, Lamberto

    2007-05-30

    Enriched environment (EE) has been recently shown to affect visual cortex development and plasticity, and to prevent dark rearing effects. The factors mediating EE effects on visual cortical development and plasticity are still unclear. We have investigated whether IGF-1 is involved in mediating EE effects on the developing visual cortex. We show that EE increases the number of IGF-1 positive neurons in the visual cortex at P18. Increasing IGF-1 in the visual cortex of non-EE rats by means of osmotic minipumps implanted at P18 mimics EE effects, accelerating visual acuity development, assessed with Visual Evoked Potentials (VEPs). Blocking IGF-1 action in the visual cortex of EE rats by means of the IGF-1 receptor antagonist JB1 from P18 completely blocks EE action on visual acuity development. These results show that IGF-1 is a key factor mediating EE effects on visual cortical development. We then show that IGF-1 affects GAD65 immunoreactivity in perisomatic innervation and the condensation of Chondroitin Sulphate Proteoglycans (CSPGs) in perineuronal nets (PNNs) in the visual cortex. This suggests that IGF-1 action in mediating EE effects could be exerted through the modulation of intracortical inhibitory circuitry and PNN development.

  1. Working with women prisoners who seriously harm themselves: ratings of staff expressed emotion (EE).

    2011-02-01

    Prison staff are repeatedly exposed to prisoners' suicidal behaviours; this may impair their capacity to care. Expressed emotion (EE), as a descriptor of the 'emotional climate' between people, has been associated with challenging behaviour in closed environments, but not previously applied to working alliances in a prison. To investigate the feasibility of rating EE between staff and suicidal women in prison; to test the hypothesis that most such staff-inmate alliances would be rated high EE. All regular staff on two small UK prison units with high suicidal behaviour rates were invited to participate. An audiotaped five-minute speech sample (FMSS) about work with one nominated suicidal prisoner was embedded in a longer research interview, then rated by two trained raters, independent of the interview process and the prison. Seven prison officers and 8 clinically qualified staff completed interviews; 3 refused, but 17 others were not interviewed, reasons including not having worked long enough with any one such prisoner. Participants and non-participants had similar relevant backgrounds. Contrary to our hypothesis, EE ratings were generally 'low'. As predicted, critical comments were directed at high frequency oppositional behaviour. EE assessments with prison staff are feasible, but our sample was small and turnover of prisoners high, so the study needs replication. Attributions about problem behaviour to illness, and/or traumatic life experience, tend to confirm generally supportive working relationships in this sample. Copyright © 2010 John Wiley & Sons, Ltd.

  2. Probing the Higgs with angular observables at future e+e- colliders

    NASA Astrophysics Data System (ADS)

    Liu, Zhen

    2016-10-01

    I summarize our recent works on using differential observables to explore the physics potential of future e+e- colliders in the framework of Higgs effective field theory. This proceeding is based upon Refs. 1 and 2. We study angular observables in the e+e-→ ZHℓ+ℓ-bb¯ channel at future circular e+e- colliders such as CEPC and FCC-ee. Taking into account the impact of realistic cut acceptance and detector effects, we forecast the precision of six angular asymmetries at CEPC (FCC-ee) with center-of-mass energy s = 240 GeV and 5 (30) ab-1 integrated luminosity. We then determine the projected sensitivity to a range of operators relevant for the Higgsstrahlung process in the dimension-6 Higgs EFT. Our results show that angular observables provide complementary sensitivity to rate measurements when constraining various tensor structures arising from new physics. We further find that angular asymmetries provide a novel means of constraining the “blind spot” in indirect limits on supersymmetric scalar top partners. We also discuss the possibility of using ZZ-fusion at e+e- machines at different energies to probe new operators.

    2014-08-01

    17α-ethynylestradiol (EE2) is a synthetic hormone, which is a derivative of the natural hormone, estradiol (E2). EE2 is an orally bio-active estrogen, and is one of the most commonly used medications for humans as well as livestock and aquaculture activity. EE2 has become a widespread problem in the environment due to its high resistance to the process of degradation and its tendency to (i) absorb organic matter, (ii) accumulate in sediment and (iii) concentrate in biota. Numerous studies have reported the ability of EE2 to alter sex determination, delay sexual maturity, and decrease the secondary sexual characteristics of exposed organisms even at a low concentration (ng/L) by mimicking its natural analogue, 17β-estradiol (E2). Thus, the aim of this review is to provide an overview of the science regarding EE2, the concentration levels in the environment (water, sediment and biota) and summarize the effects of this compound on exposed biota at various concentrations, stage life, sex, and species. The challenges in respect of EE2 include the extension of the limited database on the EE2 pollution profile in the environment, its fate and transport mechanism, as well as the exposure level of EE2 for better prediction and definition revision of EE2 toxicity end points, notably for the purpose of environmental risk assessment.

    Cystine-knot microproteins exhibit several properties that make them highly interesting as scaffolds for oral peptide drug delivery. It was therefore the aim of the study to evaluate the novel clinically relevant cystine-knot microprotein McoEeTI regarding its potential for oral delivery. Additionally, based on the gained results, important features of McoEeTI were improved. Enzymatic degradation was caused by chymotrypsin, trypsin and porcine small intestinal juice whereas McoEeTI was stable towards elastase, membrane bound proteases, pepsin and porcine gastric juice. Only minor McoEeTI degradation was observed during a 24h incubation period in rat plasma. In the presence of various physiological ions about 50% of McoEeTI formed di- and/or trimers. P(app) value of McoEeTI was determined to be (7.4+/-0.4)x10(-6)cm/s. Sodium caprate and polycarbophil-cysteine (PCP-Cys) had no beneficial effect on McoEeTI permeation, whereas the utilization of a chitosan-thiobutylamidine (Chito-TBA) system improved McoEeTI permeation 3-fold. Enzymatic stability could be strongly improved by the utilization of Bowman-Birk-Inhibitor (BBI) as well as PCP-Cys. In conclusion, this study indicates that McoEeTI represents a promising candidate as a novel scaffold for oral peptide drug delivery.

    2009-05-01

    In December 2008 Jeff Hopkins of the Hopkins Phoenix Observatory (HPO) put out a request for assistance in extracting data from images taken by the AAVSO SRO (Sonoita Research Observatory) of EE Cephei, an 11th magnitude (V) long period (5.6 years) eclipsing binary star system that was due to eclipse in January of 2009. The Hopkins Phoenix Observatory originally planned to do BVRI CCD photometry of EE Cephei for the 2009 eclipse, but equipment and logistical changes at HPO meant the EE Cephei project would not be possible. However, in the fall of 2008 Arne Henden of the AAVSO announced the availability of a remote robotic 16" telescope (the Sonoita Research Observatory) in southern Arizona for use by members of the AAVSO. Jeff Hopkins contacted Arne Henden and arrangements were made to have the EE Cephei star system imaged with BVRI filters beginning in November 2008 and running through February 2009. Image files were archived on the AAVSO web site. Soon after his initial request went out, Jeff Hopkins was contacted by John Pye from Maui Community College, who agreed to help with the project by having one of his students, Lauren Elder, examine the image files and extract EE Cephei and 3 comparison stars flux (ADU) counts for each band. The resulting data were then sent to the Hopkins Phoenix Observatory for data reduction and analysis. The project was a successful joint collaboration with 40 nights of observations for over 300 BVRI data points from 20 November 2008 to 17 February 2009. Light curves for each band as well as color indices were plotted and eclipse contact points were determined. The data were also contributed to the EE Cephei Campaign organized by Cezary Galan at the Centre for Astronomy at Nicolaus Copernicus University in Torun (Poland). Our results are plotted along with those of several dozen other observers from around the world.

  8. e+e- collisions in the multi-TeV region

    Ellis, J.

    1983-05-01

    A leading role in the elucidation of the Standard Model during the last few years has been played by e+e- colliding beam experiments. The e+e- discoveries have been made possible by the cleanliness of the experimental conditions and the ability to tune the centre-of-mass energy with precision to the desired value, thus avoiding less interesting background events. We expect history to repeat itself in the next step of elucidating physics beyond the Standard Model. Just as past e+e- machines such as SPEAR, DORIS and CESR have uncovered physics inaccessible to hadron-hadron collisions with a centre-of-mass energy several times higher, so we feel that future e+e- colliders will provide information that could not be duplicated by hadron colliders with much larger centre-of-mass energies. There is a general consensus that the next interesting energy range is likely to be in the TeV range. It is in this energy range that whatever physics provides and stabilizes the masses of the intermediate vector bosons must be revealed. Unravelling this mass generation mechanism takes us beyond the gauge principle of the Standard Model which has been so triumphantly vindicated in recent months. Therefore we discuss here the capabilities and attributes of an e+e- collider with at least 1 TeV energy per beam. We believe that by enabling an important new energy domain to be explored in detail, such an e+e- collider provides physics opportunities which cannot be paralled by hadron-hadron colliding rings with centre-of-mass energies several times higher.

    Purpose: The purpose of this work is to present a platform for designing and executing studies that compare pathologists interpreting histopathology of whole slide images (WSI) on a computer display to pathologists interpreting glass slides on an optical microscope. Methods: Here we present eeDAP, an evaluation environment for digital and analog pathology. The key element in eeDAP is the registration of theWSI to the glass slide. Registration is accomplished through computer control of the microscope stage and a camera mounted on the microscope that acquires images of the real time microscope view. Registration allows for the evaluation of the same regions of interest (ROIs) in both domains. This can reduce or eliminate disagreements that arise from pathologists interpreting different areas and focuses the comparison on image quality. Results: We reduced the pathologist interpretation area from an entire glass slide (≈10-30 mm)2 to small ROIs <(50 um)2. We also made possible the evaluation of individual cells. Conclusions: We summarize eeDAP's software and hardware and provide calculations and corresponding images of the microscope field of view and the ROIs extracted from the WSIs. These calculations help provide a sense of eeDAP's functionality and operating principles, while the images provide a sense of the look and feel of studies that can be conducted in the digital and analog domains. The eeDAP software can be downloaded from code.google.com (project: eeDAP) as Matlab source or as a precompiled stand-alone license-free application.

  12. Are “normal hips” being labeled as femoroacetabular impingement due to EE angle?

    Abstract Gluteal muscle contracture (GMC) is a clinical syndrome characterized by gait abnormality and limb dysfunction, as well as secondary deformities of pelvis and femur. Femoroacetabular impingement (FAI) typically could be diagnosed on the basis of computed tomography (CT) such as the equatorial-edge angle (EE angle), but it did not work well in GMC patients. In this study, we retrospected all image data and found small EE angles in GMCs, which meant retroverted acetabulum; however, none of them showed no symptoms and signs of FAI. Therefore, we had reasons to think that, some normal hips with unbalanced hip myodynamia as same as GMCs, may be incorrectly diagnosed as FAI through measuring EE angle only. In consequence, the paper was designed to assess the use of the EE angle in the assessment of FAI in the diagnosis, as described by Werner. Twenty-three patients (46 hips) were collected and calculated with the “equatorial-edge angle” (EE angle) by CT scans. All of them were excluded from FAI. Review of the hips showed a mean EE angle was 12.93°, with a minimum of -3.42° and a maximum of 24.08°. The mean value for males and females were 13.52° and 12.40°, respectively, without statistical significance, although the mean value of left hips and right sides reached 13.32° and 12.54° individually, not having statistical differences neither. There were not any symptoms or signs of FAI in all patients. Thus, the reduced EE angle could suggest the local excessive coverage of the femoral head by the anterior acetabular edge, but might not be a reasonably good predictor of FAI. GMC patient's acetabular deformity mainly manifests as increased retroversion, which may be the anatomical basis for FAI and lead to high risks of the acetabular impingement. However, all patients in this study showed no symptoms and signs of FAI, suggesting that the measurement of EE angle can only be applied to assessing those people with normal hip myodynamia, and the bone

  20. A novel enzyme-linked immunosorbent assay for ethynylestradiol using a long-chain biotinylated EE2 derivative.

    Schneider, Christian; Schöler, Heinz F; Schneider, Rudolf J

    2004-04-01

    Ethynylestradiol (EE2) is one of the most potent endocrine disrupting compounds capable to induce estrogenic effects even at trace level concentrations in the aquatic environment. Methods for detecting EE2 in such concentrations are generally based on GC or HPLC coupled to at least one mass spectrometer. Another approach are immunoassays and sensor systems but for most designs, derivatives of EE2 are required (e.g. for coupling to carrier proteins, enzyme or fluorescent labels, etc.). Here we present the straightforward synthesis and complete characterization of a new long-chain biotinylated EE2 derivative. The new EE2 derivative is used as tracer in a direct competitive enzyme-linked immunosorbent assay (ELISA) for the determination of EE2. With pure water, the limit of detection (LOD, signal-to-noise ratio, S/N = 3) and the test midpoint were found to be 14 and 136 ng l(-1), respectively. Cross reactivity (CR) was tested for 10 endogenous steroids and the BSA-conjugate used for immunization, as well as a synthetic precursor of the conjugate. Among the naturally occurring compounds, CR was determined to be maximum for metabolites of EE2 conjugated at ring-position 3 (17% and 37% for 3-glucuronide and 3-sulphate, respectively). Assay stability was tested against humic substances and organic solvents. Increasing amounts of organic solvents in the sample caused a clear decrease in sensitivity, presence of humic substances lead to an overestimation of EE2.

    2011-02-01

    Ee;CDKF;1 protein is a leafy spurge (Euphorbia esula) CDK-activating kinase that is involved in a phosphorylation cascade linked to early stages of cell cycle progression. Yeast two-hybrid screening performed using Ee;CDKF;1 as a bait indicated that one of the interacting proteins was Ee;CDKF;1. Protein-protein interaction of Ee;CDKF;1 was further confirmed by yeast two-hybrid interaction and in vitro pull-down assays. Gel exclusion chromatography and/or native PAGE showed that GST-CDKF;1, MBP-CDKF;1, GST-CDKF;1 devoid of GST, and endogenous Ee;CDKF;1 were capable of forming homo protein complexes which are in dimer, trimer, and/or higher molecular-mass complex in its native state. In addition, Ee;CDKF;1 complexes were autophosphorylated and able to phosphorylate CDK. Moreover, mutant forms of Ee;CDKF;1 (106G/A, 166K/A), which lost autophosphorylation capability completely, were unable to form homo protein complexes in their native state. The result thus demonstrated that autophosphorylation of Ee;CDKF;1 is crucial for both kinase activity and complex formation. Published by Elsevier Ireland Ltd.

    The global problem of microbial resistance to antibiotics has resulted in an urgent need to develop new antimicrobial agents. Natural antimicrobial peptides are considered promising candidates for drug development. Echinoderms, which rely on innate immunity factors in the defence against harmful microorganisms, are sources of novel antimicrobial peptides. This study aimed to isolate and characterise antimicrobial peptides from the Edible sea urchin Echinus esculentus. Using bioassay-guided purification and cDNA cloning, three antimicrobial peptides were characterised from the haemocytes of the sea urchin; two heterodimeric peptides and a cysteine-rich peptide. The peptides were named EeCentrocin 1 and 2 and EeStrongylocin 2, respectively, due to their apparent homology to the published centrocins and strongylocins isolated from the green sea urchin Strongylocentrotus droebachiensis. The two centrocin-like peptides EeCentrocin 1 and 2 are intramolecularly connected via a disulphide bond to form a heterodimeric structure, containing a cationic heavy chain of 30 and 32 amino acids and a light chain of 13 amino acids. Additionally, the light chain of EeCentrocin 2 seems to be N-terminally blocked by a pyroglutamic acid residue. The heavy chains of EeCentrocins 1 and 2 were synthesised and shown to be responsible for the antimicrobial activity of the natural peptides. EeStrongylocin 2 contains 6 cysteines engaged in 3 disulphide bonds. A fourth peptide (Ee4635) was also discovered but not fully characterised. Using mass spectrometric and NMR analyses, EeCentrocins 1 and 2, EeStrongylocin 2 and Ee4635 were all shown to contain post-translationally brominated Trp residues in the 6 position of the indole ring.

  2. V-ATPase activity in the TGN/EE is required for exocytosis and recycling in Arabidopsis.

    In plants, vacuolar H(+)-ATPase (V-ATPase) activity acidifies both the trans-Golgi network/early endosome (TGN/EE) and the vacuole. This dual V-ATPase function has impeded our understanding of how the pH homeostasis within the plant TGN/EE controls exo- and endocytosis. Here, we show that the weak V-ATPase mutant deetiolated3 (det3) displayed a pH increase in the TGN/EE, but not in the vacuole, strongly impairing secretion and recycling of the brassinosteroid receptor and the cellulose synthase complexes to the plasma membrane, in contrast to mutants lacking tonoplast-localized V-ATPase activity only. The brassinosteroid insensitivity and the cellulose deficiency defects in det3 were tightly correlated with reduced Golgi and TGN/EE motility. Thus, our results provide strong evidence that acidification of the TGN/EE, but not of the vacuole, is indispensable for functional secretion and recycling in plants.

  3. Proceedings, High-Precision $\\alpha_s$ Measurements from LHC to FCC-ee

    2015-01-01

    This document provides a writeup of all contributions to the workshop on "High precision measurements of $\\alpha_s$: From LHC to FCC-ee" held at CERN, Oct. 12--13, 2015. The workshop explored in depth the latest developments on the determination of the QCD coupling $\\alpha_s$ from 15 methods where high precision measurements are (or will be) available. Those include low-energy observables: (i) lattice QCD, (ii) pion decay factor, (iii) quarkonia and (iv) $\\tau$ decays, (v) soft parton-to-hadron fragmentation functions, as well as high-energy observables: (vi) global fits of parton distribution functions, (vii) hard parton-to-hadron fragmentation functions, (viii) jets in $e^\\pm$p DIS and $\\gamma$-p photoproduction, (ix) photon structure function in $\\gamma$-$\\gamma$, (x) event shapes and (xi) jet cross sections in $e^+e^-$ collisions, (xii) W boson and (xiii) Z boson decays, and (xiv) jets and (xv) top-quark cross sections in proton-(anti)proton collisions. The current status of the theoretical and experimental uncertainties associated to each extraction method, the improvements expected from LHC data in the coming years, and future perspectives achievable in $e^+e^-$ collisions at the Future Circular Collider (FCC-ee) with $\\cal{O}$(1--100 ab$^{-1}$) integrated luminosities yielding 10$^{12}$ Z bosons and jets, and 10$^{8}$ W bosons and $\\tau$ leptons, are thoroughly reviewed. The current uncertainty of the (preliminary) 2015 strong coupling world-average value, $\\alpha_s(m_Z)$ = 0.1177 $\\pm$ 0.0013, is about 1\\%. Some participants believed this may be reduced by a factor of three in the near future by including novel high-precision observables, although this opinion was not universally shared. At the FCC-ee facility, a factor of ten reduction in the $\\alpha_s$ uncertainty should be possible, mostly thanks to the huge Z and W data samples available.

  4. Long-term EEJ variations by using the improved EE-index

    In 2008, International Center for Space Weather Science and Education, Kyushu University (ICSWSE) proposed the EE-index, which is an index to monitor the equatorial geomagnetic phenomena. EE-index has been improved with the development of the MAGnetic Data Acquisition System and the Circum-pan Pacific Magnetometer Network (MAGDAS/CPMN) and the enormous archive of MAGDAS/CPMN data over 10 years since the initial article. Using the improved EE-index, we examined the solar cycle variation of equatorial electrojet (EEJ) by the time series analysis for EUEL (one part of EE-index) at Ancon in Peru and the solar activity from September 18, 1998 to March 31, 2015. We found that the long-term variation of daily EEJ peak intensity has a trend similar to that of F10.7 (the solar activity). The power spectrum of the daily EEJ peak has clearly two dominant peaks throughout the analysis interval: 14.5 days and 180 days (semi-annual). The solar cycle variation of daily EEJ peak correlates well with that of F10.7 (the correlation coefficient 0.99). We conclude that the daily EEJ peak intensity is roughly determined as the summation of the long-period trend of the solar activity resulting from the solar cycle and day-to-day variations caused by various sources such as lunar tides, geometric effects, magnetospheric phenomena and atmospheric phenomena. This work presents the primary evidence for solar cycle variations of EEJ on the long-term study of the EE-index

  5. Photocatalytic degradation of 17α-ethinylestradiol (EE2) in the presence of TiO2-doped zeolite.

    Current design limitations and ineffective remediation techniques in wastewater treatment plants have led to concerns about the prevalence of pharmaceutical and personal care products (PPCPs) in receiving waters. A novel photocatalyst, TiO2-doped low-silica X zeolite (TiO2-LSX), was used to study the degradation of the pharmaceutical compound, 17α-ethinylestradiol (EE2). The catalyst was synthesized and characterized using XRD, BET surface analysis, SEM-EDAX, and ICP-OES. The effects of different UV light intensities, initial EE2 concentrations, and catalyst dosages on the EE2 removal efficiency were studied. A higher EE2 removal efficiency was attained with UV-TiO2-LSX when compared with UV-TiO2 or UV alone. The EE2 degradation process followed pseudo-first-order kinetics. A comprehensive empirical model was developed to describe the EE2 degradation kinetics under different conditions using multiple linear regression analysis. The EE2 degradation mechanism was proposed based on molecular calculations, identification of photoproducts using HPLC-MS/MS, and reactive species quenching experiments; the results showed that oxidative degradation pathways initiated by hydroxyl radicals were predominant. This novel TiO2-doped zeolite system provides a promising application for the UV disinfection process in wastewater treatment plants.

    The target lesion revascularization of paclitaxel-eluting stents (PES) has been reported to be lower than that of sirolimus-eluting stents in patients on hemodialysis (HD). However, the comparison of PES and second generation drug-eluting stents in CKD patients has not been fully investigated. We compared clinical outcomes of everolimus-eluting stents (EES) and PES in CKD patients. Hundred and forty seven CKD patients (eGFR<60mLmin(-1)1.73m(-2)) treated with PES (n=74, from May 2007 to December 2009) and EES (n=73, from January 2010 to January 2013) were enrolled in the study. Major adverse cardiac events (MACEs) were defined as death, non-fatal myocardial infarction, and ischemia driven target lesion revascularization. The incidence of 36-month MACE was significantly lower in EES, non-HD group compared to PES, non HD group (0% in EES group and 13.5% in PES group, respectively, P<0.01). There was no significant difference in MACE between EES and PES in HD patients (5.4% in PES group and 5.5% in EES group, P=0.98). In multivariate analysis, PES group and PES ISR were independent factors for worse incidence of MACE. In CKD patients, PES was associated with worse clinical outcomes in non-HD patients as compared with EES. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

    2012-09-01

    Discriminant analysis (DA) was performed on data of two combined hormonal contraceptives (CHC) differing in estrogen ratio to explore whether a combination of variables rather than a single variable distinguishes CHCs better. Data were used of a parallel study in premenopausal women treated for three cycles (21 days on, 7 days off) with a contraceptive vaginal ring delivering Nestorone and ethinyl estradiol (EE) or an oral contraceptive containing levonorgestrel and EE. DA was performed on the change from baseline (CFB) and the end-of-treatment values at 3 months for lipids, sex-hormone binding globulin (SHBG), C-reactive protein, angiotensinogen, blood pressure and hemostasis variables, and on the hemostasis variables only. For the complete set, the CFB for factor VII (FVII), SHBG and plasminogen (PLG), or end-of-treatment SHBG- and FVII level discriminated the treatments best. Maximal discrimination for the hemostasis data was by CFB for FVII and PLG or end-of-treatment FVII level. DA identifies differences between CHCs and may provide information on the factors associated with thrombotic risk. Copyright © 2012 Elsevier Inc. All rights reserved.

    Toxic effects induced by exposure to endocrine-disrupting chemicals during fetal and neonatal periods can be irreversible and exert effects throughout an animal's entire life. Our previous study showed that neonatal exposure to 17α-ethynyl estradiol (EE) induced irregular estrous cycle in adults. To uncover the reason for the delayed effect after neonatal exposure to EE, reproductive parameters including ovarian weight, ovarian steroidogenesis, and hormonal profiles were investigated in developing female rats. Ovarian weight decreased at postnatal days (PND) 14 and 21 after neonatal exposure to EE. Ovarian histology at PND21 showed that the ratio of follicles with a diameter >300μm decreased and the ratio of follicles with a diameter of 100-150μm increased in EE-treated ovaries, indicating that neonatal exposure to EE retarded follicular development. Moreover, the expression of P450arom increased at PND14 and the expressions of inhibin/activin subunits βA and βB decreased at PND21 in EE-treated ovaries. Consistent with the expression of P450arom, circulating levels of 17β-estradiol increased at PND14 in EE-treated animals. Furthermore, the circulating levels of luteinizing hormone (LH) also increased at PND14 in the treated animals. Although the expression of Kiss1 did not change in the anteroventral periventricular nucleus (AVPV) of the hypothalamus between controls and EE-treated rats, the expression of Kiss1 was reduced in the arcuate nucleus (ARC) of the hypothalamus at PND14. Based upon those results, we suggest that neonatal exposure to EE disrupted the system regulating the interactions between the reproductive hormones and follicle development in pre-pubertal rats, which may result in reproduction dysfunction in adulthood.

    We study the production of the spin partner of the X (3872), which is a D*Dbar* bound state with quantum numbers JPC =2++ and named X2 (4012) here, with the associated emission of a photon in electron-positron collisions. The results show that the ideal energy region to observe the X2 (4012) in e+e- annihilations is from 4.4 GeV to 4.5 GeV, due to the presence of the S-wave Dbar*D1 (2420) and Dbar*D2 (2460) thresholds, respectively. We also point out that it will be difficult to observe the γX (4012) at the e+e- center-of-mass energy around 4.26 GeV.

    Data from the Pierre Auger Observatory are analyzed to search for anisotropies near the direction of the Galactic Centre at EeV energies. The exposure of the surface array in this part of the sky is already significantly larger than that of the fore-runner experiments. Our results do not support previous findings of localized excesses in the AGASA and SUGAR data. We set an upper bound on a point-like flux of cosmic rays arriving from the Galactic Centre which excludes several scenarios predicting sources of EeV neutrons from Sagittarius A. Also the events detected simultaneously by the surface and fluorescence detectors (the ‘hybrid’ data set), which have better pointing accuracy but are less numerous than those of the surface array alone, do not show any significant localized excess from this direction.

  12. Phenomenology of a Higgs triplet model at future e+e- colliders

    In this work, we investigate the prospects of future e+e- colliders in testing a Higgs triplet model with a scalar triplet and a scalar singlet under S U (2 ). The parameters of the model are fixed so that the lightest C P -even state corresponds to the Higgs particle observed at the LHC at around 125 GeV. This study investigates if the second heaviest C P -even, the heaviest C P -odd and the singly charged states can be observed at existing and future colliders by computing their accessible production and decay channels. In general, the LHC is not well equipped to produce a Higgs boson which is not mainly doubletlike, so we turn our focus to lepton colliders. We find distinctive features of this model in cases where the second heaviest C P -even Higgs is tripletlike, singletlike or a mixture. These features could distinguish the model from other scenarios at future e+e- colliders.

    Simultaneous measurements of air showers with the fluorescence and surface detectors of the Pierre Auger Observatory allow a sensitive search for EeV photon point sources. Several Galactic and extragalactic candidate objects are grouped in classes to reduce the statistical penalty of many trials from that of a blind search and are analyzed for a significant excess above the background expectation. The presented search does not find any evidence for photon emission at candidate sources, and combined p-values for every class are reported. Particle and energy flux upper limits are given for selected candidate sources. These limits significantly constrain predictions of EeV proton emission models from non-transient Galactic and nearby extragalactic sources, as illustrated for the particular case of the Galactic center region.

    The KTeV/E799 experiment at Fermilab has searched for the rare kaon decay K(L)-->pi(0)e(+)e(-). This mode is expected to have a significant CP violating component. The measurement of its branching ratio could support the standard model or could indicate the existence of new physics. This Letter reports new results from the 1999-2000 data set. One event is observed with an expected background at 0.99+/-0.35 events. We set a limit on the branching ratio of 3.5x10(-10) at the 90% confidence level. Combining with the previous result based on the data set taken in 1997 yields the final KTeV result: BR(K(L)-->pi(0)e(+)e(-))<2.8x10(-10) at 90% C.L.

  15. Slow down of a globally neutral relativistic e-e+ beam shearing the vacuum

    The microphysics of relativistic collisionless shear flows is investigated in a configuration consisting of a globally neutral, relativistic {{e}-}{{e}+} beam streaming through a hollow plasma/dielectric channel. We show through multidimensional particle-in-cell simulations that this scenario excites the mushroom instability (MI), a transverse shear instability on the electron-scale, when there is no overlap (no contact) between the {{e}-}{{e}+} beam and the walls of the hollow plasma channel. The onset of the MI leads to the conversion of the beam’s kinetic energy into magnetic (and electric) field energy, effectively slowing down a globally neutral body in the absence of contact. The collisionless shear physics explored in this configuration may operate in astrophysical environments, particularly in highly relativistic and supersonic settings where macroscopic shear processes are stable.

  16. Beyond Higgs couplings: Probing the Higgs with angular observables at future e$^{+}$e$^{-}$ colliders

    Here, we study angular observables in the $ {e}^{+}{e}^{-}\\to ZH\\to {\\ell}^{+}{\\ell}^{-}b\\overline{b} $ channel at future circular e$^{+}$ e$^{-}$ colliders such as CEPC and FCC-ee. Taking into account the impact of realistic cut acceptance and detector effects, we forecast the precision of six angular asymmetries at CEPC (FCC-ee) with center-of-mass energy $ \\sqrt{s}=240 $ GeV and 5 (30) ab$^{-1}$ integrated luminosity. We then determine the projected sensitivity to a range of operators relevant for he Higgs-strahlung process in the dimension-6 Higgs EFT. Our results show that angular observables provide complementary sensitivity to rate measurements when constraining various tensor structures arising from new physics. We further find that angular asymmetries provide a novel means of both probing BSM corrections to the HZγ coupling and constraining the “blind spot” in indirect limits on supersymmetric scalar top partners.

  17. Boost to h →Z γ : From LHC to future e+e- colliders

    No, Jose Miguel; Spannowsky, Michael

    2017-04-01

    A precise measurement of the Higgs h →Z γ decay is very challenging at the LHC, due to the very low branching fraction and the shortage of kinematic handles to suppress the large SM Z γ background. We show how such a measurement would be significantly improved by considering Higgs production in association with a hard jet. We compare the prospective HL-LHC sensitivity in this channel with other Higgs production modes where h is fairly boosted, e.g. weak boson fusion, and also to the potential h →Z γ measurement achievable with a future e+e- circular collider (fcc-ee). Finally, we discuss new physics implications of a precision measurement of h →Z γ .

  19. Relating e+e- annihilation to high energy scattering at weak and strong coupling

    NASA Astrophysics Data System (ADS)

    Hatta, Yoshitaka

    2008-11-01

    We explore the correspondence between the final state in e+e- annihilation and the small-x hadronic wavefunction in the transverse plane both in weakly coupled QCD and strongly coupled Script N = 4 SYM. At strong coupling, the virtual and static photon produced in e+e- annihilation can be treated as a shock wave propagating in AdS space leaving spherical energy and charge distributions on the boundary. This is shown to be mathematically identical to the computation of energy and charge distributions in the transverse plane generated by a high energy color singlet state. At weak coupling, the correspondence is useful in studying interjet observables. By performing the stereographic projection to the BFKL equation, we construct an exact solution to the evolution equation derived by Marchesini and Mueller, and find the angular distribution of small-x gluons in the interjet region. Finally we argue that the correspondence holds also for the energy correlation functions.

    The mechanism of baryon-anti-baryon pair production in e+e- annihilation into hadrons has been studied using the TOPAZ detector at the TRISTAN e+e- collider at an average center-of-mass energy of 58 GeV. The distributions of various p¯p correlations were compared with two prominent models: the cluster-fragmentation model and the string-fragmentation model. We rejected the cluster-fragmentation model at the 90% C.L. Furthermore, in the context of the string-fragmentation model, we favor the ``popcorn'' model, rejecting the ``diquark'' model, where a diquark is considered to be a fundamental entity, at the 95% C.L.

    Data from the Pierre Auger Observatory are analyzed to search for anisotropies near the direction of the Galactic Centre at EeV energies. The exposure of the surface array in this part of the sky is already significantly larger than that of the fore-runner experiments. Our results do not support previous findings of localized excesses in the AGASA and SUGAR data. We set an upper bound on a point-like flux of cosmic rays arriving from the Galactic Centre which excludes several scenarios predicting sources of EeV neutrons from Sagittarius A. Also the events detected simultaneously by the surface and fluorescence detectors (the ''hybrid'' data set), which have better pointing accuracy but are less numerous than those of the surface array alone, do not show any significant localized excess from this direction.

    Hot Dry Rock (HDR) geothermal energy well EE-2 at Fenton Hill, New Mexico, was sidetracked and redrilled into the HDR Phase II reservoir after two unsuccessful attempts to repair damage in the lower wellbore. Before sidetracking was begun, six cement slurries were pumped to plug the abandoned lower wellbore and to support the production casing where drilling wear was predicted and where sidetracking was to occur. This work and the redrill of EE-2A were completed in November 1987. Specifications were prepared for a state-of-the-art tie-back casing, which was procured, manufactured, and delivered to Fenton Hill in May 1988. The well was then completed in June 1988 for hot-water production service by cementing in a liner and the upper section of production casing and installing and cementing a tie-back casing string. 24 refs., 17 figs., 5 tabs.

    The latest data released by the BABAR Collaboration on azimuthal correlations measured for pion-kaon and kaon-kaon pairs produced in e+e- annihilations allow, for the first time, a direct extraction of the kaon Collins functions. These functions are then used to compute the kaon Collins asymmetries in semi-inclusive deep inelastic scattering processes, which result in good agreement with the measurements performed by the HERMES and COMPASS collaborations.

    New measurements of the Collins asymmetries were performed by BABAR exploiting inclusive e+e- → h1h2 X annihilations (with h1,2 = π and/or K) mainly at the energy of the ϒ(4S), which corresponds to a squared transferred momentum Q2 ~ 110 GeV2c4. For the first time asymmetries following strange quarks fragmentation could be derived as a function of the fractional energy carried out by inclusively emitted hadron pairs.

    Although (E,E)-8,10-Dodecadien-l-ol was reported to be a sex pheromone of the codling moth [Laspeyresia pomonella (L.)], its presence in the moth was questioned, mainly because it has not been isolated. A computerized search of data from gas chromatography-mass spectrometry of a partially purified extract equivalent to 45 abdominal tips of female moths produced a mass spectrum that matched that of the authentic coinpound. Other data also confirmed the presence of the compound.

    We explore the scenarios where the only accessible new states at the electroweak scale consist of a pair of color-singlet electroweak particles, the masses of which are degenerate at the tree level and split only by electroweak symmetry breaking at the loop level. For the sake of illustration, we consider a supersymmetric model and study the following three representative cases with the lower-lying states as (a) two spin-1 /2 Higgsino SU(2 ) L doublets, (b) a spin-1 /2 wino SU(2 ) L triplet and (c) a spin-0 left-handed slepton SU(2 ) L doublet. Due to the mass degeneracy, those lower-lying electroweak states are difficult to observe at the LHC and rather challenging to detect at the e+e- collider as well. We exploit the pair production in association with a hard photon radiation in high energy e+e- collisions. If kinematically accessible, such single-photon processes at e+e- colliders with polarized beams enable us to characterize each scenario by measuring the energy of the associated hard photon and to determine the spin of the nearly invisible particles unambiguously through the threshold behavior in the photon energy distribution.

    Wild Triticeae grasses serve as important gene pools for forage and cereal crops. Understanding their genome compositions is pivotal for efficient use of this vast gene pool in germplasm-enhancement programs. Several cleaved amplified polymorphic sequence (CAPS) markers were developed to distinguish the Eb, Ee, and R genomes. With the aid of disomic addition lines of wheat, it was confirmed that all 7 chromosomes of Eb, Ee, and R genomes carry these genome-specific CAPS markers. Thus, the identified CAPS markers are useful in detecting and monitoring the chromosomes of these 3 genomes. This study also provides evidence suggesting that some Purdue and Chinese germplasm lines developed for barley yellow dwarf virus (BYDV) resistance are different from those developed in Australia. Furthermore, Thinopyrum intermedium and Thinopyrum ponticum were shown to have different genome constitutions. Sequence analyses of the 1272 bp sequences, containing Ty3/gypsy retrotransposons, from the Eb, Ee, and R genomes also shed light on the evolution of these 3 genomes.

    This study proposed a novel method to extract endmembers from hyperspectral image based on discrete firefly algorithm (EE-DFA). Endmembers are the input of many spectral unmixing algorithms. Hence, in this paper, endmember extraction from hyperspectral image is regarded as a combinational optimization problem to get best spectral unmixing results, which can be solved by the discrete firefly algorithm. Two series of experiments were conducted on the synthetic hyperspectral datasets with different SNR and the AVIRIS Cuprite dataset, respectively. The experimental results were compared with the endmembers extracted by four popular methods: the sequential maximum angle convex cone (SMACC), N-FINDR, Vertex Component Analysis (VCA), and Minimum Volume Constrained Nonnegative Matrix Factorization (MVC-NMF). What's more, the effect of the parameters in the proposed method was tested on both synthetic hyperspectral datasets and AVIRIS Cuprite dataset, and the recommended parameters setting was proposed. The results in this study demonstrated that the proposed EE-DFA method showed better performance than the existing popular methods. Moreover, EE-DFA is robust under different SNR conditions.

    Die Flexibilisierung der Fertigung und kurze Produktzyklen setzen einen beschleunigten, möglichst fehlerfreien Entwicklungsprozess voraus. Dieses Ziel kann jedoch nur erreicht werden, wenn bereits parallel zur Hardwareentwicklung die Software mit Hilfe einer Simulation der Hardware entwickelt und getestet werden kann. Darüber hinaus können mit Simulationen alternative Lösungen studiert werden, die zu optimierten Verfahren führen. In dieser Arbeit werden Leistungstests an der Simulationsumgebung drd-Simulator präsentiert, die auf der J2EE-Technologie1 basiert. Für die Messungen wird eine Soft-SPS eingesetzt, deren Feldbus vom Typ ModbusTCP simuliert wird. Erste Messungen zeigen, dass J2EE eine leistungsstarke und skalierbare Plattform für die Realisierung von Feldbussimulationen ist. In einem Zyklusbereich ab 100 ms ist das E/A-Verhalten echtzeitfähig, wobei meherere Steuerungen auf den Bus zugreifen können. Die J2EE-Technologie zeichnet sich zudem durch eine gute Ausfallsicherheit und dynamische Rekonfigurier-barkeit aus, so dass Tests dynamisch zur Laufzeit ergänzt oder verändert werden können.

    We present a search for a neutral, long-lived particle L that is produced in e+e- collisions and decays at a significant distance from the e+e- interaction point into various flavor combinations of two oppositely charged tracks. The analysis uses an e+e- data sample with a luminosity of 489.1 fb-1 collected by the BABAR detector at the ϒ (4 S ) , ϒ (3 S ) , and ϒ (2 S ) resonances and just below the ϒ (4 S ) . Fitting the two-track mass distribution in search of a signal peak, we do not observe a significant signal, and set 90% confidence level upper limits on the product of the L production cross section, branching fraction, and reconstruction efficiency for six possible two-body L decay modes as a function of the L mass. The efficiency is given for each final state as a function of the mass, lifetime, and transverse momentum of the candidate, allowing application of the upper limits to any production model. In addition, upper limits are provided on the branching fraction B (B →XsL ) , where Xs is a strange hadronic system.

    Protein complexes perform an array of crucial cellular functions. Elucidating their non-covalent interactions and dynamics is paramount for understanding the role of complexes in biological systems. While the direct characterization of biomolecular assemblies has become increasingly important in recent years, native fractionation techniques that are compatible with downstream analysis techniques, including mass spectrometry, are necessary to further expand these studies. Nevertheless, the field lacks a high-throughput, wide-range, high-recovery separation method for native protein assemblies. Here, we present clear native gel-eluted liquid fraction entrapment electrophoresis (CN-GELFrEE), which is a novel separation modality for non-covalent protein assemblies. CN-GELFrEE separation performance was demonstrated by fractionating complexes extracted from mouse heart. Fractions were collected over 2 hr and displayed discrete bands ranging from ~30 to 500 kDa. A consistent pattern of increasing molecular weight bandwidths was observed, each ranging ~100 kDa. Further, subsequent reanalysis of native fractions via SDS-PAGE showed molecular-weight shifts consistent with the denaturation of protein complexes. Therefore, CN-GELFrEE was proved to offer the ability to perform high-resolution and high-recovery native separations on protein complexes from a large molecular weight range, providing fractions that are compatible with downstream protein analyses.

  2. ON THE SPIN CORRELATIONS OF MUONS AND TAU LEPTONS GENERATED IN THE ANNIHILATION PROCESSES e+e- → μ+μ-, e+e- → τ+τ-

    2014-12-01

    Using the technique of helicity amplitudes, the electromagnetic process e+e- → μ+μ-(τ+τ-) is theoretically studied in the one-photon approximation. The structure of the triplet states of the final (μ+μ-) system is analyzed. It is shown that in the case of unpolarized electron and positron the final muons are also unpolarized, but their spins are strongly correlated. Explicit expressions for the components of the correlation tensor of the (μ+μ-) system are derived. The formula for the angular correlation at the decays of final muons μ+ and μ- is obtained. It is demonstrated that spin correlations of muons in the considered process have the purely quantum character, since one of the Bell-type incoherence inequalities for the correlation tensor components is always violated.

  3. QCD compositeness as revealed in exclusive vector boson reactions through double-photon annihilation: e+e- → γγ* → γV0 and e+e- → γ*γ* → V0V0

    We study the exclusive double-photon annihilation processes, e+e- → γγ* → γV0 and e+e- →γ*γ* → Va0 Vb0, where the Vi0 is a neutral vector meson produced in the forward kinematical region: s ≫ - t and - t ≫ ΛQCD2. We show how the differential cross sections dσ/dt, as predicted by QCD, have additional falloff in the momentum transfer squared t due to the QCD compositeness of the hadrons, consistent with the leading-twist fixed-θCM scaling laws, both in terms of conventional Feynman diagrams and by using the AdS/QCD holographic model to obtain the results more transparently. However, even though they are exclusive channels and not associated with the conventional electron-positron annihilation process e+e- →γ* → q q bar , these total cross sections σ (e+e- → γV0) and σ (e+e- → Va0 Vb0), integrated over the dominant forward- and backward-θCM angular domains, scale as 1 / s, and thus contribute to the leading-twist scaling behavior of the ratio Re+e-. We generalize these results to exclusive double-electroweak vector-boson annihilation processes accompanied by the forward production of hadrons, such as e+e- →Z0V0 and e+e- →W-ρ+. These results can also be applied to the exclusive production of exotic hadrons such as tetraquarks, where the cross-section scaling behavior can reveal their multiquark nature.

    Context. EE Cep is an unusual long-period (5.6 yr) eclipsing binary discovered during the mid-twentieth century. It undergoes almost-grey eclipses that vary in terms of both depth and duration at different epochs. The system consists of a Be type star and a dark dusty disk around an invisible companion. EE Cep together with the widely studied ɛ Aur are the only two known cases of long-period eclipsing binaries with a dark, dusty disk component responsible for periodic obscurations. Aims: Two observational campaigns were carried out during the eclipses of EE Cep in 2003 and 2008/9 to verify whether the eclipsing body in the system is indeed a dark disk and to understand the observed changes in the depths and durations of the eclipses. Methods: Multicolour photometric data and spectroscopic observations performed at both low and high resolutions were collected with several dozen instruments located in Europe and North America. We numerically modelled the variations in brightness and colour during the eclipses. We tested models with different disk structure, taking into consideration the inhomogeneous surface brightness of the Be star. We considered the possibility of disk precession. Results: The complete set of observational data collected during the last three eclipses are made available to the astronomical community. The 2003 and 2008/9 eclipses of EE Cep were very shallow. The latter is the shallowest among all observed. The very high quality photometric data illustrate in detail the colour evolution during the eclipses for the first time. Two blue maxima in the colour indices were detected during these two eclipses, one before and one after the photometric minimum. The first (stronger) blue maximum is simultaneous with a "bump" that is very clear in all the UBV(RI)C light curves. A temporary increase in the I-band brightness at the orbital phase ~0.2 was observed after each of the last three eclipses. Variations in the spectral line profiles seem to be

    According to the rotational splitting law of g modes, the frequency spectra of EE Cam can be disentangled only with oscillation modes of ℓ = 0, 1, and 2. Fifteen sets of rotational splits were found, and they contain five sets of ℓ = 1 multiplets and 10 sets of ℓ = 2 multiplets. The rotational period of EE Cam is deduced to be {P}{rot}={1.84}-0.05+0.07 days. When we do model fittings, we use two nonradial oscillation modes (f 11 and f 32), and the fundamental radial mode f 1. The fitting results show that {χ }2 of the best-fitting model is much smaller than those of other theoretical models. The physical parameters of the best-fitting model are M = 2.04 M ⊙, Z = 0.028, T eff = 6433 K, {log}L/{L}ȯ =1.416, R = 4.12 R ⊙, {log}g=3.518, and {χ }2=0.00035. Furthermore, we find that f 11 and f 32 are mixed modes, which mainly characterize the features of the helium core. The fundamental radial mode f 1 mainly restricts the features of the stellar envelope. Finally, the acoustic radius {τ }0 and the period separation Π0 are determined to be 5.80 hr and 463.7 s, respectively, and the size of the helium core of EE Cam is estimated to be M He = 0.181 M ⊙ and R He = 0.0796 R ⊙.

    The regular consumption of large mammal carcasses, as evidenced by butchery marks on fossils recovered from Early Stone Age archaeological sites, roughly coincides with the appearance of Homo habilis. However, the significance of this niche expansion cannot be appreciated without an understanding of hominin feeding behavior and their ecological interactions with mammalian carnivores. The Olduvai Geochronology and Archaeology Project (OGAP) has recovered a large and well-preserved fossil assemblage from the HWK EE site, which was deposited just prior to the first appearance of Acheulean technology at Olduvai Gorge and likely represents one of the last H. habilis sites at Olduvai. This taphonomic analysis of the larger mammal fossil assemblage excavated from HWK EE shows evidence of multiple occupations over a long period of time, suggesting the site offered resources that were attractive to hominins. There was a water source indicated by the presence of fish, crocodiles, and hippos, and there was possible tree cover in an otherwise open habitat. The site preserves several stratigraphic intervals with large fossil and artifact assemblages within two of these intervals. Feeding traces on bone surfaces suggest hominins at the site obtained substantial amounts of flesh and marrow, particularly from smaller size group 1-2 carcasses, and exploited a wide range of taxa, including megafauna. A strong carnivore signal suggests hominins scavenged much of their animal foods during the two main stratigraphic intervals. In the later interval, lower carnivore tooth mark and hammerstone percussion mark frequencies, in addition to high epiphyseal to shaft fragment ratios, suggest hominins and carnivores did not fully exploit bone marrow and grease, which may have been acquired from nutritionally-stressed animals that died during a dry period at Olduvai. The diversity of fauna that preserve evidence of butchery suggests that the HWK EE hominins were opportunistic in their

    We have built a low background detector, a time projection chamber surrounded by an active anti-Compton, to measure the overlineνee - elastic cross section down to the antineutrino energy of 900 keV. With our detector, running at 18 m from the core of a nuclear reactor in Bugey, we could detect reactor antineutrinos by measuring both the energy and the direction of the recoiling electrons. We report here on a first analysis of the data using an automatic scanning procedure. The results we obtain are 1.5 σ higher than the ones predicted by the standard model.

    The fractal characteristics of multiparticle final state are first studied in the e+e- collision of s = 250GeV, with the MC simulation generator Jetset7.4 and Herwig5.9. The results show that this multiparticle final state has a double-Hurst-exponent fractals characteristics, which means that the resulting NFM obeys the scaling law well using both the two sets of Hurst exponents to partition the three-dimensional phase space isotropically and anisotropically. Their fractal indices and the effective fluctuation strength are also predicted.

    Since December 2010, the CMD-3 detector has collected data at the electronpositron collider VEPP-2000. The sample of the accumulated data corresponds to about 60 pb-1 of integrated luminosity in the c.m. energy from 0.32 up to 2 GeV. Preliminary results of the analysis of various processes e+e- annihilation to hadrons are presented. It is shown the processes with multihadron events have several intermediate states which must be taken into account to correctly describe the angular and invariant mass distributions as well as cross section dependence versus energy.

    Cross-section distributions are calculated for the reaction e+e- → J / ψ → Λ bar (→ p bar π+) Λ (→ pπ-), and related annihilation reactions mediated by vector mesons. The hyperon-decay distributions depend on a number of structure functions that are bilinear in the, possibly complex, psionic form factors GMψ and GEψ of the Lambda hyperon. The relative size and relative phase of these form factors can be uniquely determined from the unpolarized joint-decay distributions of the Lambda and anti-Lambda hyperons. Also the decay-asymmetry parameters of Lambda and anti-Lambda hyperons can be determined.

    The use of resonant depolarization has been suggested for precise beam energy measurements (better than 100 keV) in the e+e- Future Circular Collider (FCC-e+e-) for Z and WW physics at 45 and 80 GeV beam energy respectively. Longitudinal beam polarization would benefit the Z peak physics program; however it is not essential and therefore it will be not investigated here. In this paper the possibility of self-polarized leptons is considered. As a result, preliminary results of simulations in presence of quadrupole misalignments and beam position monitors (BPMs) errors for a simplified FCC-e+e- ring are presented.

    The cross sections for the multiple production of the lightest neutral Higgs boson at high-energy e+e- colliders are presented in the framework of the Minimal Supersymmetric extension of the Standard Model (MSSM). We consider production through Higgs-strahlung, associated production of the scalar and the pseudoscalar bosons, and the fusion mechanisms for which we use the effective longitudinal vector-boson approximation. These cross sections allow one to determine trilinear Higgs couplings λHhh and λhhh, which are theoretically determined by the Higgs potential.

    Brinjal is an important vegetable crop. Major crop loss of brinjal is due to insect attack. Insect-resistant EE-1 brinjal has been developed and is awaiting approval for commercial release. Consumer health concerns and implementation of international labelling legislation demand reliable analytical detection methods for genetically modified (GM) varieties. End-point and real-time polymerase chain reaction (PCR) methods were used to detect EE-1 brinjal. In end-point PCR, primer pairs specific to 35S CaMV promoter, NOS terminator and nptII gene common to other GM crops were used. Based on the revealed 3' transgene integration sequence, primers specific for the event EE-1 brinjal were designed. These primers were used for end-point single, multiplex and SYBR-based real-time PCR. End-point single PCR showed that the designed primers were highly specific to event EE-1 with a sensitivity of 20 pg of genomic DNA, corresponding to 20 copies of haploid EE-1 brinjal genomic DNA. The limits of detection and quantification for SYBR-based real-time PCR assay were 10 and 100 copies respectively. The prior development of detection methods for this important vegetable crop will facilitate compliance with any forthcoming labelling regulations. Copyright © 2012 Society of Chemical Industry.

    In plants, vacuolar H+-ATPase (V-ATPase) activity acidifies both the trans-Golgi network/early endosome (TGN/EE) and the vacuole. This dual V-ATPase function has impeded our understanding in how the pH homeostasis within the plant TGN/EE controls exo- and endocytosis. Here, we show that the weak V-ATPase mutant deetiolated3 (det3) displayed a pH increase in the TGN/EE, but not in the vacuole, strongly impairing secretion and recycling of the brassinosteroid receptor and the cellulose synthase complexes to the plasma membrane, in contrast to mutants lacking tonoplast-localized V-ATPase activity only. The brassinosteroid insensitivity and the cellulose deficiency defects in det3 were tightly correlated with reduced Golgi and TGN/EE motility. Thus, our results provide strong evidence that acidification of the TGN/EE, but not of the vacuole, is indispensable for functional secretion and recycling in plants. PMID:27250258

    2015-01-01

    This study is part of a project to investigate the transverse momentum dependence in parton distribution and fragmentation functions, analyzing (semi-)inclusive high-energy processes within a proper QCD framework. We calculate the transverse-momentum-dependent (TMD) multiplicities for e+e- annihilation into two hadrons (considering different combinations of pions and kaons) aiming to investigate the impact of intrinsic and radiative partonic transverse momentum and their mixing with flavor. Different descriptions of the non-perturbative evolution kernel (see, e.g., Refs. [1-5]) are available on the market and there are 200 sets of flavor configurations for the unpolarized TMD fragmentation functions (FFs) resulting from a Monte Carlo fit of Semi-Inclusive Deep-Inelastic Scattering (SIDIS) data at Hermes (see Ref. [6]). We build our predictions of e+e- multiplicities relying on this rich phenomenology. The comparison of these calculations with future experimental data (from Belle and BaBar collaborations) will shed light on non-perturbative aspects of hadron structure, opening important insights into the physics of spin, flavor and momentum structure of hadrons.

    It has been recently found that the development of electromagnetic instabilities between shearing, globally neutral polarisable dielectric slabs, separated by a nanometer-scale gap, can result in an effective non-contact friction force between slavs, which is the classical analogue of the quantum friction effect proposed by Pendry (1997). This effect has been explored analytically in the sub-relativistic regime, where the development of unstable electromagnetic modes parallel to the direction of motion are responsible for the non-contact friction effect. We explore the interaction of a relativistic, globally neutral e-e + beam streaming through a hollow plasma/dielectric in the absence of overlap (no contact). We show through analytic theory and 3D particle-in-cell simulations that this relativistic scenario excites unstable electromagnetic modes transverse to the direction of propagation. The onset of this electromagnetic instability leads to the conversion of the kinetic energy of the e-e + beam into electric and magnetic field energy, effectively slowing down a relativistic, globally neutral body in the absence of contact. We demonstrate that this effect be explored using beam properties that are readily available at the SLAC National Accelerator Laboratory.

    We study the transverse momentum distributions of single inclusive hadron production in e+e- annihilation processes. Although the only available experimental data are scarce and quite old, we find that the fundamental features of transverse momentum dependent (TMD) evolution, historically addressed in Drell-Yan processes and, more recently, in Semi-inclusive deep inelastic scattering processes, are visible in e+e- annihilations as well. Interesting effects related to its non-perturbative regime can be observed. We test two different parameterizations for the p⊥ dependence of the cross section: the usual Gaussian distribution and a power-law model. We find the latter to be more appropriate in describing this particular set of experimental data, over a relatively large range of p⊥ values. We use this model to map some of the features of the data within the framework of TMD evolution, and discuss the caveats of this and other possible interpretations, related to the one-dimensional nature of the available experimental data.

    2016-05-01

    In an e+e- B factory, charmonium states can be produced through different mechanisms, e.g. direct production in e+e- annihilation, double charmonium production, and in B-meson decays. Prompt production of J/ψ or ψ(2S) in association with a second charmonium states has been observed by both the BABAR and the Belle experiments. These processes provide an opportunity to study both perturbative and non perturbative effects in QCD and to search for new charmonium states recoiling against the reconstructed J/ψ or ψ(2S). Using the full BABAR data set collected at the ϒ(4S) resonance, we measure the absolute branching fractions of the two-body decays of B mesons (B → KXc), where Xc is a charmonium state. For events in which a B is fully reconstructed, the charmonium spectrum can be observed in an unbiased way by looking at the distribution of the K momentum in the rest frame of the recoiling B. We present also Dalitz plot analysis for the decays of B mesons to D- D0 K+ and D¯ 0 D0 K+, and we report about the observation of the Ds1 * (2700)+ resonance in these two channels, and obtain measurements of the mass and width.

    HWK EE is a little-known archaeological site from the top of Lower Bed II and the basal part of Middle Bed II, Olduvai Gorge, Tanzania. The site was originally excavated in the early 1970s by Mary Leakey, but the excavations and resulting lithic and fossil assemblages were never described. Here we report for the first time on the lithic and fossil assemblages that were recovered by Mary Leakey from the site. The lithic assemblage is one of the largest of any Oldowan site and is characterized by a core-and-flake technology with simple flaking techniques and minimal reduction of cores. Retouched flake frequencies and battered tools are higher than those reported for Olduvai Bed I and Lower Bed II assemblages, but flaking schemes are poorly organized. The fossil assemblage is well-preserved, taxonomically-rich, but dominated by bovids, and includes abundant feeding traces of both hominins and carnivores. Hominins are inferred to have broken the majority of limb bones at the site for access to marrow, while both carnivores and hominins likely had access to at least some flesh. HWK EE may represent one of the last Homo habilis sites at Olduvai Gorge, and is important to understanding the behavioral and cultural mechanisms that led to the emergence of the Acheulean and Homo erectus in the region.

    2009-07-01

    A dark sector—a new non-Abelian gauge group Higgsed or confined near the GeV scale—can be spectacularly probed in low-energy e+e- collisions. A low-mass dark sector can explain the annual modulation signal reported by DAMA/LIBRA and the PAMELA, ATIC, and INTEGRAL observations by generating small mass splittings and new interactions for weak-scale dark matter. Some of these observations may be the first signs of a low-mass dark sector that collider searches can definitively confirm. Production and decay of O(GeV)-mass dark states is mediated by a Higgsed Abelian gauge boson that mixes kinetically with hypercharge. Existing data from BABAR, BELLE, CLEO-c, and KLOE may contain thousands of striking dark-sector events with a high multiplicity of leptons that reconstruct mass resonances and possibly displaced vertices. We discuss the production and decay phenomenology of Higgsed and confined dark sectors and propose e+e- collider search strategies. We also use the DAMA/LIBRA signal to estimate the production cross sections and decay lifetimes for dark-sector states.

We then determine the projected sensitivity to a range of operators relevant for he Higgs-strahlung process in the dimension-6 Higgs EFT.

    The e+e- → KS0 KL0 cross section has been measured in the center-of-mass energy range 1004-1060 MeV at 25 energy points using 6.1 ×105 events with KS0 →π+π- decay. The analysis is based on 5.9 pb-1 of an integrated luminosity collected with the CMD-3 detector at the VEPP-2000 e+e- collider. To obtain ϕ (1020) meson parameters the measured cross section is approximated according to the Vector Meson Dominance model as a sum of the ρ , ω , ϕ-like amplitudes and their excitations. This is the most precise measurement of the e+e- → KS0 KL0 cross section with a 1.8% systematic uncertainty.

  12. Determination of estrogenic steroids and microbial and photochemical degradation of 17α-ethinylestradiol (EE2) in lake surface water, a case study.

    In this study, a GC-MS technique was applied to determine 17α-ethinylestradiol (EE2), an active ingredient of oral contraceptives, and its fate in Lake Quinsigamond, Massachusetts, USA. To the knowledge of the authors, this is the first study of EE2 and its microbial and photochemical degradation in a lake ecosystem. EE2 was detected at a concentration up to 11.1 ng L(-1). At this concentration EE2 may affect the reproduction of fish and other aquatic organisms in the lake due to its high estrogenic activity. EE2 was persistent to the biodegradation by the microorganisms in the lake. Under aerobic conditions a long lag phase (42 days) was observed before the biodegradation of EE2 and a half-life of 108 days was estimated. Under anaerobic conditions, EE2 experienced even a longer acclimation stage (63 days) and a slower microbial degradation in the lake water. The photodegradation of EE2 was rapid in the lake surface water under natural sunlight, with a half-life of less than 2 days in summer sunny days. Compared to biodegradation, photodegradation may represent a predominant removal mechanism for EE2 in natural surface waters.

    Effect of age on the response of EE(sub TD) to an increase in gravity was assessed in young (Y; 1.5 month old) and mature (M; 8 month old) Sprague-Dawley rats. Rats were implanted with transmitters to monitor activity, and metabolism was determined by the double labeled water technique. Daily food intake was measured. For each age, rats (n=8 per treatment) were exposed to centrifugation at 2G, or remained at 1G. There was a difference in EE(sub TD) between age groups, 182 plus or minus 11 and 143 plus or minus 5 kcal/kg/day in Y and M, respectively. This difference was attributed in part to a lower activity level in M animals, 48% of Y rats. After day 6 there was no effect on EE(sub TD) of exposure to 2G, or on food intake per 100g BW. Prior studies show a 20% increase in resting EE with hypergravity. In our study the level of activity was reduced to 41% of 1G in both age groups during 2G. For Y at 1G resting EE accounted for 78% of the EE(sub TD) and activity 22%, while at 2G resting EE was 96% of EE(sub TD) and activity 4%. M rats had similar changes. Independent of age, with exposure to hypergravity EE(sub TD) is maintained by behavioral changes.

    High-throughput screening for asymmetric catalysts has stimulated an interest in optically-based enantiomeric-excess (ee) sensors, primarily for their improved time and cost efficiency when compared to the standard HPLC analysis. We present herein substituent-effect studies on a recently reported Zn(II) multicomponent assembly that is used for chiral, secondary alcohol ee detemination. The systematic altering of assemblies formed from select substituted pyridyl ligands pointed to the conclusion that steric effects dominate the mode of interaction at the pyridyl 3- and 6- positions. From these results we identified a new Zn(II)-centered multicomponent assembly with a higher dynamic range than previously reported. Calibration curves of the CD signals resulting from the new assembly led to an ee assay with a 1.7% error. To further the utility of the new assembly, a correlation was developed between alcohol substituent size to the respective enantiopure CD value.

    From direct observations of the longitudinal development of ultra-high energy air showers performed with the Pierre Auger Observatory, upper limits of 3.8%, 2.4%, 3.5% and 11.7% (at 95% c.l.) are obtained on the fraction of cosmic-ray photons above 2, 3, 5 and 10 EeV (1EeV≡1018eV), respectively. These are the first experimental limits on ultra-high energy photons at energies below 10 EeV. The results complement previous constraints on top-down models from array data and they reduce systematic uncertainties in the interpretation of shower data in terms of primary flux, nuclear composition and proton-air cross-section.

  17. Use of drospirenone/ethinyl estradiol (DRSP/EE) among women with acne reduces acne treatment-related resources.

    Acne is a common dermatologic condition that extends into middle age, particularly among women, and is associated with substantial healthcare resource utilization. Drospirenone (DRSP), a synthetic progestin, has anti-androgenic activity, and women using DRSP 3.0 mg/ethinyl estradiol (EE) 0.02 mg as a 24/4 regimen (DRSP/EE-24/4) for contraception also may use it for treatment of moderate acne. The study used a US national healthcare database to assess acne-related healthcare resource utilization among women aged 18-45 years before (pre-index) and after (post-index) initiation of DRSP/EE-24/4. Resource utilization and costs were evaluated by age group (18-25, 26-35, or 36-45 years) and by type of acne medication (systemic antibiotic, topical, or anti-androgen). Data for 1340 women were evaluated. Overall, drug costs, medical costs, and total costs were decreased by 38%, 37%, and 37%, respectively (p<0.0001 for all) between the pre-index and post-index periods; significant differences were evident across age groups and acne medication categories. Total costs were significantly decreased for patients (41%) and healthcare plans (36%; p<0.0001 for both) overall and across age groups and drug classes. Acne-related claims and number of days using acne medication were reduced (by 37% each; p<0.0001 for both). The study was retrospective in design and had a limited follow-up period. Database limitations restricted assessment of medication compliance and adherence. DRSP/EE-24/4 use was associated with substantial reductions in acne-related healthcare resource utilization, and reductions occurred regardless of age or type of acne medication. DRSP/EE-24/4 therefore represents a cost-effective option for the treatment of acne among women using DRSP/EE-24/4 for oral contraception.

    We present the first next-to-next-to-leading-logarithmic resummation for the two-jet rate in e+e- annihilation in the Durham and Cambridge algorithms. The results are obtained by extending the ares method to observables involving any global, recursively infrared and collinear safe jet algorithm in e+e- collisions. As opposed to other methods, this approach does not require a factorization theorem for the observables. We present predictions matched to next-to-next-to-leading order and a comparison to LEP data.

    We report studies of ultrahigh-energy cosmic-ray composition via analysis of depth of air shower maximum (X(max)), for air shower events collected by the High-Resolution Fly's Eye (HiRes) observatory. The HiRes data are consistent with a constant elongation rate d/d[log(E)] of 47.9+/-6.0(stat)+/-3.2(syst) g/cm2/decade for energies between 1.6 and 63 EeV, and are consistent with a predominantly protonic composition of cosmic rays when interpreted via the QGSJET01 and QGSJET-II high-energy hadronic interaction models. These measurements constrain models in which the galactic-to-extragalactic transition is the cause of the energy spectrum ankle at 4x10(18) eV.

  20. e-/e+ Accelerating Structure with Cyclic Variation of Azimuth Asymmetry

    Krasnykh, A.; /SLAC

    2007-03-05

    A classical electron/positron accelerating structure is a disk-loaded cylindrical waveguide. The accelerator structure here has azimuth symmetry. The proposed structure contains a disk-loaded cylindrical waveguide where there is a periodical change of RF-field vs. azimuth. The modulation deforms the rf-field in such a manner that the accelerated particles undergo transverse focusing forces. The new class of accelerator structures covers the initial part of e+/e- linacs where a bunch is not rigid and additional transverse focusing fields are necessary. We discuss a bunch formation with a high transverse aspect ratio in the proposed structure and particularly in the photoinjector part of a linac.

  1. Study of isospin violating phi excitation in e+e- → ωπ0

    We study the reaction e+e- → ωπ0 in the vicinity of the phi mass region. The isospin-violating phi excitation is accounted for by two major mechanisms. One is electromagnetic transition and the other is strong isospin violations. For the latter, we consider contributions from the intermediate hadronic meson loops and phi-ρ0 mixing as the major mechanisms via the t- and s-channel transitions, respectively. By fitting the recent KLOE data, we succeed in constraining the model parameters and extracting the phi → ωπ0 branching ratio. It shows that the branching ratio is sensitive to the phi excitation line shape and background contributions. Some crucial insights into the correlation between isospin violation and Okubo-Zweig-Iizuka rule evading transitions are also learned.

    We have estimated hadronic backgrounds for an e+e- linear collider at a center- of-mass energy of 5 TeV. In order to achieve a required luminosity in TeV e+ e- colliders, the high beamstrahlung parameter {Upsilon}, such as several thousands, is caused. In the high {Upsilon} regime, the {gamma}{gamma} luminosities due to the collision of beamstrahlung photons are calculated by using the CAIN code. According to the {gamma}{gamma} luminosity distribution, we have estimated the hadronic backgrounds of {gamma}{gamma} {yields} minijets based on the parton distributions of the Drees and Grassie model by the PYTHIA 5.7 code. The Japan Linear Collider (J LC-1) detector simulator is applied for selection performances in the detector.

    EE Aqr is a 7.9 mag Algol variable with a 12 hr orbital period. The Wilson-Devinney program is used to simultaneously solve 11 previously published light curves together with two existing radial velocity curves. The resulting masses are M {sub 1} = 2.24 {+-} 0.13 M {sub sun} and M {sub 2} = 0.72 {+-} 0.04 M {sub sun}, and the radii are R {sub 1} = 1.76 {+-} 0.03 R {sub sun} and R {sub 2} = 1.10 {+-} 0.02 R {sub sun}. The system has the lower-mass component completely filling its Roche lobe. Its distance from Hipparcos observations is 112 {+-} 10 pc. An improved ephemeris is derived, and no deviations in the period over time were seen. Light and velocity curve parameters, orbital elements, and absolute dimensions are presented, plus a comparison is made with previous solutions.

    HOPKINS, A.M.

    2007-06-08

    An engineering evaluation/cost analysis (EE/CA) was performed at the Hanford Site's Plutonium Finishing Plant (PFP). The purpose of the EVCA was to identify the sub-grade items to be evaluated; determine the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA) hazardous substances through process history and available data; evaluate these hazards; and as necessary, identify the available alternatives to reduce the risk associated with the contaminants. The sub-grade EWCA considered four alternatives for an interim removal action: (1) No Action; (2) Surveillance and Maintenance (S&M); (3) Stabilize and Leave in Place (Stabilization); and (4) Remove, Treat and Dispose (RTD). Each alternative was evaluated against the CERCLA criteria for effectiveness, implementability, and cost.

    We present theoretical analysis of paired Bc mesons production in e+e- annihilation at different energy scales taking into account full next-to-leading order QCD corrections. Both possible electroweak channels are considered: production via virtual photon and via virtual Z-boson. We study in detail the role of radiative QCD corrections, which were found to be significant especially at low energies. It is shown that the contribution from Z-boson is significant at high energies (√{ s} >MZ / 2) especially in the case of paired production of pseudo-scalar and vector (Bc +Bc*) mesons. Azimuthal asymmetry induced by a P-violating weak interaction with Z-boson is also analyzed.

    High-throughput experimentation (HTE) has emerged as a widely used technology that accelerates discovery and optimization processes with parallel small-scale reaction setups. A high-throughput screening (HTS) method capable of comprehensive analysis of crude asymmetric reaction mixtures (eliminating product derivatization or isolation) would provide transformative impact by matching the pace of HTE. We report how spontaneous in situ construction of stereodynamic metal probes from readily available, inexpensive starting materials can be applied to chiroptical chemosensing of the total amount, enantiomeric excess (ee), and absolute configuration of a wide variety of amines, diamines, amino alcohols, amino acids, carboxylic acids, α-hydroxy acids, and diols. This advance and HTS potential are highlighted with the analysis of 1 mg of crude reaction mixtures of a catalytic asymmetric reaction. This operationally simple assay uses a robust mix-and-measure protocol, is amenable to microscale platforms and automation, and provides critical time efficiency and sustainability advantages over traditional serial methods.

    Deuteron and anti-deuteron production in Z decays has been observed in the ALEPH experiment at LEP. The production rate of anti-deuterons is measured to be (5.9±1.8±0.5)×10 per hadronic Z decay in the anti-deuteron momentum range from 0.62 to 1.03 GeV/c. The coalescence parameter B, which characterizes the likelihood of anti-deuteron production, is measured to be 0.0033±0.0013 GeV in Z decays. These measurements indicate that the production of anti-deuterons is suppressed in ee collisions compared to that in pp and photoproduction collisions.

    We observe D0-D ¯0 mixing in the decay D0→K+π- using a data sample of integrated luminosity 976 fb-1 collected with the Belle detector at the KEKB e+e- asymmetric-energy collider. We measure the mixing parameters x'2=(0.09±0.22)×10-3 and y'=(4.6±3.4)×10-3 and the ratio of doubly Cabibbo-suppressed to Cabibbo-favored decay rates RD=(3.53±0.13)×10-3, where the uncertainties are statistical and systematic combined. Our measurement excludes the no-mixing hypothesis at the 5.1 standard deviation level.

  10. Stellar dynamics in E+E pairs of galaxies. 2: Simulations and interpretation

    We have presented in a companion article a kinematic study of three E+E galaxy pairs, NGC741/742, 1587/1588 (CPG 99) and 2672/2673 (CPG 175). We find some evidence for perturbed velocity dispersion profiles. These perturbation features are now reported for 14 galaxies in the literature. They occur, or require observations for detection, at large radii where the S/N in the data is low. While observations of individual galaxies are sometimes uncertain, the large number of objects where such features are suspected gives confidence that they are real. These perturbations can be attributed to projection effects contamination along the line of sight, or directly to the tidal interaction. We report the results of several self-gravitating simulations of unbound pairs in an effort to better understand these perturbations another generic features of close E+E pairs reported in the literature. The models frequently show off-center envelopes created by the asymmetry of tidal forces during interpenetrating encounters. The envelopes last for a few 108 yrs, which explains the frequency of such features in observed pairs. This phenomenon is stronger in the self-gravitating simulations than in the MTBA runs. U-shaped (and an equal number of inverse U shaped velocity profiles are seen in the simulations, a result of ablation in the outer envelopes. Simulations including inner galaxy rotation also preserve this feature, irrespective of the spin vector direction in each galaxy. U-shape velocity structure is found to be a robust indicator of the ongoing interaction. All simulations show evidence for enhanced velocity dispersion between the galaxies even in the case of simple superposition of two non interacting objects. We therefore conclude that this cannot be considered an unambiguous indicator of the interaction.

  11. Exotic decays of the 125 GeV Higgs boson at future e+e- colliders

    The discovery of unexpected properties of the Higgs boson would offer an intriguing opportunity to shed light on some of the most profound puzzles in particle physics. Beyond Standard Model (BSM) decays of the Higgs boson could reveal new physics in a direct manner. Future electron-positron lepton colliders operating as Higgs factories, including CEPC, FCC-ee and ILC, with the advantages of a clean collider environment and large statistics, could greatly enhance sensitivity in searching for these BSM decays. In this work, we perform a general study of Higgs exotic decays at future e+e- lepton colliders, focusing on the Higgs decays with hadronic final states and/or missing energy, which are very challenging for the High-Luminosity program of the Large Hadron Collider (HL-LHC). We show that with simple selection cuts, (10-3-10-5) limits on the Higgs exotic decay branching fractions can be achieved using the leptonic decaying spectator Z boson in the associated production mode e+e-→ ZH. We further discuss the interplay between detector performance and Higgs exotic decays, and other possibilities of exotic decays. Our work is a first step in a comprehensive study of Higgs exotic decays at future lepton colliders, which is a key area of Higgs physics that deserves further investigation.

    Although the molecular basis of variability of hemoglobin (Hb) F has been extensively examined in β-thalassemia and sickle cell diseases, less study has been done on Hb E disorder. To address the variability of Hb F expression in Hb EE disease, we have examined multiple single nucleotide polymorphisms (SNPs) in the β-globin gene cluster, BCL11A and HBS1L-MYB genes and determined their associations with Hb F levels in this syndrome. Study was done on 141 adult Thai individuals with homozygous Hb E. Hematological parameters were recorded and Hb F measured using Hb-HPLC analyzer. It was found in 26 cases that co-inheritance of α-thalassemia could lead to significant lower production of Hb F. Association of Hb F expression with the (G)γ-Xmn I polymorphism and other SNPs including rs2297339, rs2838513, rs4895441 and rs9399137 in HBS1L-MYB gene and rs4671393 and rs11886868 in BCL11A gene was therefore analyzed in the remaining 115 cases without α-thalassemia. It was found that 4 of these 7 SNPs including (G)γ-XmnI polymorphism (rs7482144), HBS1L-MYB (rs4895441) and (rs9399137) and BCL11A (rs4671393) were significantly associated with higher proportions of subjects with high Hb F (Hb F≥5%). The result demonstrated that multiple genetic modifying factors including T allele of (G)γ-XmnI polymorphism (rs7482144), G allele of HBS1L-MYB (rs489441), C allele of HBS1L-MYB (rs9399137) and C allele of BCL11A (rs4671393) are associated with increased Hb F and in combination could explain approximately 80% of the variation of Hb F in Hb EE disease in Thai population. Other genetic factors regulating Hb F expression in this common genetic disorder remains to be elucidated. Copyright © 2014 Elsevier Inc. All rights reserved.

  13. The HLS approach to (g - 2)μ : A Solution to the "τ versus e+e-" Puzzle

    NASA Astrophysics Data System (ADS)

    Benayoun, Maurice

    2016-04-01

    The Hidden Local Symmetry (HLS) Model provides a framework able to encompass several physical processes and gives a unfied description of these in an energy range extending up to the ø mass. Supplied with appropriate symmetry breaking schemes, the HLS Model gives a broken Effective Lagrangian (BHLS). The BHLS Lagrangian gives rise to a fit procedure in which a simultaneous description of the e+e- annihilations to π+π-, π0γ, ηγ, π+π-π0, K+K-, KLKS and of the dipion spectrum in the decay τ±→π± π0v can be performed. Supplemented with a few pieces of information on the ρ0 - ω - ø system, the τ dipion spectrum is shown to predict accurately the pion form factor in e+e- annihilations. Physics results derived from global fits involving or excluding the τ dipion spectra are found consistent with each others. Therefore, no obvious mismatch between the τ and e+e- physics properties arises and the τ - e+e- puzzle vanishes within the broken HLS Model.

    The Oral Health Impact Profile is the most frequently used and validated of the Oral Health Quality of Life instruments. Several short versions have been developed; and a validation of the OHIP-49 in Spanish has been published. The objective was to develop the short version of the Oral Health Impact Profile in Spanish (OHIP-EE-14). Cross-sectional study. One hundred and thirty-one persons aged ≥60 years attending a social centre for the elderly, residents of a nursing home and persons seeking dental care at a dental school in Mexico City were interviewed and examined. The validity of each of the 49 questions was evaluated, and, to construct the short version, 14 items were selected. The perceived need for dental treatment, number of teeth, presence of coronal caries, root caries, presence of dental plaque and utilisation of removable prosthesis were measured. Internal consistency, repeatability and discriminant validity were calculated. The OHIP-EE-14 was reliable (Cronbach's-α = 0.918, ICC = 0.825). Significant associations were found between OHIP-EE-14 and the number of teeth and perceived need for dental treatment. The OHIP-EE-14 is a reliable and valid instrument and can be used in subjects aged 60 years and over from Mexico City. © 2012 The Gerodontology Society and John Wiley & Sons A/S.

    Preeclampsia (PE) is one of the most important complications of pregnancy that is associated with significant mortality and morbidity in mother and fetus. Since the etiologic factors in its development are still unclear, we aimed to examine the intercellular adhesion molecule-1 (ICAM-1) gene K469E polymorphism in preeclamptic and control healthy women. Genetic polymorphism was analyzed in 192 PE and 186 healthy control women. PCR-RFLP method was used to identify K469E polymorphism. The frequency of KK, KE, and EE genotypes of ICAM-1 gene was not different between PE patients and healthy pregnant women. Whereas, the frequency of KE and EE genotypes was significantly higher in severe PE than mild PE women and control group, and the risk of severe PE was 2.4-fold higher in subjects with KE genotype (OR, 2.4 [95% CI, 1 to 5.9]; P = 0.03) and 3.3-fold higher in subjects with EE genotype (OR, 3.3 [95% CI, 1.2 to 9]; P = 0.015) compared to individuals with KK genotype. We concluded that KE and EE genotypes of K469E polymorphism could increase risk of severe PE.

    2012-01-01

    Bt brinjal event EE-1 with cry1Ac gene, expressing insecticidal protein against fruit and shoot borer, is the first genetically modified food crop in the pipeline for commercialization in India. Qualitative polymerase chain reaction (PCR) along with event-specific conventional as well as real-time PCR methods to characterize the event EE-1 is reported. A multiplex (pentaplex) PCR system simultaneously amplifying cry1Ac transgene, Cauliflower Mosaic Virus (CaMV) 35S promoter, nopaline synthase (nos) terminator, aminoglycoside adenyltransferase (aadA) marker gene, and a taxon-specific beta-fructosidase gene in event EE-1 has been developed. Furthermore, construct-specific PCR, targeting the approximate 1.8 kb region of inserted gene construct comprising the region of CaMV 35S promoter and cry1Ac gene has also been developed. The LOD of developed EE-1 specific conventional PCR assay is 0.01%. The method performance of the reported real-time PCR assay was consistent with the acceptance criteria of Codex Alimentarius Commission ALINORM 10/33/23, with the LOD and LOQ values of 0.05%. The developed detection methods would not only facilitate effective regulatory compliance for identification of genetic traits, risk assessment, management, and postrelease monitoring, but also address consumer concerns and resolution of legal disputes.

  1. A Test in Context: E/A and E/e' to Assess Diastolic Dysfunction and LV Filling Pressure.

    PubMed

    Mitter, Sumeet S; Shah, Sanjiv J; Thomas, James D

    2017-03-21

    Diastolic dysfunction represents a combination of impaired left ventricular (LV) relaxation, restoration forces, myocyte lengthening load, and atrial function, culminating in increased LV filling pressures. Current Doppler echocardiography guidelines recommend using early to late diastolic transmitral flow velocity (E/A) to assess diastolic function, and E to early diastolic mitral annular tissue velocity (E/e') to estimate LV filling pressures. Although both parameters have important diagnostic and prognostic implications, they should be interpreted in the context of a patient's age and the rest of the echocardiogram to describe diastolic function and guide patient management. This review discusses: 1) the physiological basis for the E/A and E/e' ratios; 2) their roles in diagnosing diastolic dysfunction; 3) prognostic implications of abnormalities in E/A and E/e'; 4) special scenarios of the E/A and E/e' ratios that are either useful or challenging when evaluating diastolic function clinically; and 5) their usefulness in guiding therapeutic decision making.

    Objective To evaluate the value of free-run electromyography (f-EMG) monitoring of extraocular cranial nerves (EOCN) III, IV, and VI during expanded endonasal surgery (EES) of the skull base in reducing iatrogenic cranial nerve (CN) deficits. Design We retrospectively identified 200 patients out of 990 who had at least one EOCN monitored during EES. We further separated patients into groups according to the specific CN monitored. In each CN group, we classified patients who had significant (SG) f-EMG activity as Group I and those who did not as Group II. Results A total of 696 EOCNs were monitored. The number of muscles supplied by EOCNs that had SG f-EMG activity was 88, including CN III = 46, CN IV = 21, and CN VI = 21. There were two deficits involving CN VI in patients who had SG f-EMG activity during surgery. There were 14 deficits observed, including CN III = 3, CN IV = 2, and CN VI = 9 in patients who did not have SG f-EMG activity during surgery. Conclusions f-EMG monitoring of EOCN during EES can be useful in identifying the location of the nerve. It seems to have limited value in predicting postoperative neurological deficits. Future studies to evaluate the EMG of EOCN during EES need to be done with both f-EMG and triggered EMG. PMID:23943720

    An elevated left atrial pressure has been reported to play an important role in the development of atrial remodelling in atrial fibrillation (AF) patients. The study aimed at elucidating the association between the diastolic early transmitral flow velocity/mitral annular velocity (E/e', a non-invasive surrogate of left atrial pressure) and left atrial low-voltage-area existence, and the prognostic impact of the E/e' on procedural outcomes in patients undergoing AF ablation. Total of 215 consecutive patients were divided into 3 groups based on the estimated left atrial pressure: normal (E/e' < 8.0, n = 58), undetermined (E/e' = 8.0-14.0, n = 114), and elevated (E/e' > 14.0, n = 43). Left atrial endocardial voltage mapping was performed following pulmonary vein isolation. Patients with a high E/e' more frequently had low-voltage areas (E/e' < 8.0, 31%, E/e' = 8.0-14.0, 35%; E/e' > 14.0, 67%; P = 0.0001). After adjusting for other correlates, a high E/e' was an independent predictor of low-voltage-area existence (HR = 1.11, 95% CI = 1.02-1.21, P = 0.017). During a mean follow-up period of 12 ± 6 months, recurrent atrial tachyarrhythmias occurred in 22 (10%) patients after multiple (1.4 ± 0.5) procedures. Patients with an E/e' > 14 had more frequent recurrent atrial tachyarrhythmias after multiple ablation procedures than those with an E/e' ≤ 14 (23% vs. 7%, P = 0.001). A high E/e' obtained by pre-ablation echocardiography was associated with a left atrial arrhythmogenic substrate in patients undergoing AF ablation. Furthermore, a high E/e' predicted poor procedural outcomes after pulmonary vein isolation.

    The Oldowan site HWK EE (Olduvai Gorge, Tanzania) has yielded a large fossil and stone tool assemblage at the transition from Lower to Middle Bed II, ∼1.7 Ma. Integrated tooth wear and stable isotope analyses were performed on the three most abundant ungulate taxa from HWK EE, namely Alcelaphini, cf. Antidorcas recki (Antilopini) and Equus oldowayensis (Equini), to infer dietary traits in each taxon. Some paleodietary changes were observed for cf. A. recki and E. oldowayensis based on tooth wear at the transition from the Lemuta to the Lower Augitic Sandstone (LAS) interval within the HWK EE sequence. Stable carbon and oxygen isotope data show no significant changes in bulk diet or hydroclimate between the Lemuta and LAS intervals. The combined tooth wear and stable isotope data suggest similar paleoecological conditions across the two HWK EE intervals, but that differences in vegetation consumed among ungulates may have resulted in changes in dietary niches. Integrating tooth wear and stable isotope analyses permits the characterization of ungulate diets and habitats at HWK EE where C4 dominated and minor mixed C3 and C4 habitats were present. Our results provide a better understanding of the paleoenvironmental conditions of the Lemuta and LAS intervals. The LAS assemblage was mostly accumulated during relatively dry periods at Olduvai Gorge when grasses were not as readily available and grazing animals may have been more nutritionally-stressed than during the formation of the Lemuta assemblage. This helps to contextualize variations in hominin and carnivore feeding behavior observed from the faunal assemblages produced during the two main occupations of the site.

  6. BEEC: An event generator for simulating the Bc meson production at an e+e- collider

    NASA Astrophysics Data System (ADS)

    2013-12-01

    The Bc meson is a doubly heavy quark-antiquark bound state and carries flavors explicitly, which provides a fruitful laboratory for testing potential models and understanding the weak decay mechanisms for heavy flavors. In view of the prospects in Bc physics at the hadronic colliders such as Tevatron and LHC, Bc physics is attracting more and more attention. It has been shown that a high luminosity e+e- collider running around the Z0-peak is also helpful for studying the properties of Bc meson and has its own advantages. For this purpose, we write down an event generator for simulating Bc meson production through e+e- annihilation according to relevant publications. We name it BEEC, in which the color-singlet S-wave and P-wave (cb¯)-quarkonium states together with the color-octet S-wave (cb¯)-quarkonium states can be generated. BEEC can also be adopted to generate the similar charmonium and bottomonium states via the semi-exclusive channels e++e-→|(QQ¯)[n]>+Q+Q¯ with Q=b and c respectively. To increase the simulation efficiency, we simplify the amplitude as compact as possible by using the improved trace technology. BEEC is a Fortran program written in a PYTHIA-compatible format and is written in a modular structure, one may apply it to various situations or experimental environments conveniently by using the GNU C compiler make. A method to improve the efficiency of generating unweighted events within PYTHIA environment is proposed. Moreover, BEEC will generate a standard Les Houches Event data file that contains useful information of the meson and its accompanying partons, which can be conveniently imported into PYTHIA to do further hadronization and decay simulation.

  7. Economic and Ethical Consequences of Natural Hazards in Alpine Valleys (EE-Con)

    The Alps and their population are particularly vulnerable to geomorphological and hydrological hazards and this problem might be amplified by ongoing climate change. Natural disasters cause severe monetary damage which often leads to the difficult question whether it socially pays to protect settlements at high costs or whether alternatively settlement areas should better be abandoned. By investigations in the Johnsbachtal and the Kleinsölktal (Styria), the interdisciplinary project "Economic and Ethical Consequences of Natural Hazards in Alpine Valleys" (EE-Con), funded by the Austrian Academy of Sciences, seeks to answer the following questions: (1) Are natural hazards and associated damages in fact increasing, and is this due to meteorological triggers, to anthropogenic factors or to internal process dynamics? (2) What is the perception and knowledge of local people, how is risk and risk prevention communicated? (3) What is the respective cost ratio between protection infrastructure, soft measures of adaptation and other options (e.g. reduction of settlement area)? (4) What legitimate claims to compensation do people have, how far does societal responsibility go and where does individual responsibility start if parts of the settlement area had to be abandoned? These questions will be tackled in an interdisciplinary cooperation between geography, economics and normative theory (philosophy). EE-Con will follow broadly the path of risk analysis and risk assessment, focusing on the temporal dimension (past - present - future) with the aim to unravel the history of natural hazards in the areas and to analyse the economic values involved. In the following, natural hazard scenarios for the future (2050 and 2100) will be developed considering the economic consequences. Besides this, the project deals with local knowledge, risk perception and risk communication, which will be investigated via group interviews and stakeholder workshops and be integrated into a human

    A beam optics scheme has been designed for the future circular collider- e+e- (FCC-ee). The main characteristics of the design are: beam energy 45 to 175 GeV, 100 km circumference with two interaction points (IPs) per ring, horizontal crossing angle of 30 mrad at the IP and the crab-waist scheme [P. Raimondi, D. Shatilov, and M. Zobov, arXiv:physics/0702033; P. Raimondi, M. Zobov, and D. Shatilov, in Proceedings of the 22nd Particle Accelerator Conference, PAC-2007, Albuquerque, NM (IEEE, New York, 2007), p. TUPAN037.] with local chromaticity correction. The crab-waist scheme is implemented within the local chromaticity correction system without additional sextupoles,more » by reducing the strength of one of the two sextupoles for vertical chromatic correction at each side of the IP. So-called “tapering” of the magnets is applied, which scales all fields of the magnets according to the local beam energy to compensate for the effect of synchrotron radiation (SR) loss along the ring. An asymmetric layout near the interaction region reduces the critical energy of SR photons on the incoming side of the IP to values below 100 keV, while matching the geometry to the beam line of the FCC proton collider (FCC-hh) [A. Chancé et al., Proceedings of IPAC’16, 9–13 May 2016, Busan, Korea, TUPMW020 (2016).] as closely as possible. Sufficient transverse/longitudinal dynamic aperture (DA) has been obtained, including major dynamical effects, to assure an adequate beam lifetime in the presence of beamstrahlung and top-up injection. In particular, a momentum acceptance larger than ±2% has been obtained, which is better than the momentum acceptance of typical collider rings by about a factor of 2. The effects of the detector solenoids including their compensation elements are taken into account as well as synchrotron radiation in all magnets. The optics presented in this study is a step toward a full conceptual design for the collider. Finally, a number of issues have

    A 0.6 kb EcoRI fragment (EE0.6), cloned from the W chromosome of chickens, is a nonrepetitive sequence and contains an exonlike sequence, ET15, which is likely a part of a pseudogene. The EE0.6 sequence is conserved in all species of birds examined both in Carinatae and Ratitae. A counterpart sequence of EE0.6 is present on the Z chromosome. The extent of diversity between the W- and Z-linked sequences are variable among species. The W- and Z-linked EE0.6 sequences, cloned from 12 different species, were compared and four forward and three reverse primers were selected to amplify parts of the EE0.6 sequence by polymerase chain reaction (PCR). By choosing a suitable combination of primers for EE0.6 and a set of primers for a Z/W-common sequence, as an internal control, the sex of 36 species belonging to 16 different orders of Carinatae could be determined clearly by PCR. The sex of two other species representing different orders could be determined by Southern blot hybridization using ET15 as a probe. For the two Ratitae species, emu and ostrich, EE0.6 sequences on W and Z chromosomes could not be distinguished either by PCR or Southern blotting.

    Asymmetric Ir-catalyzed C-C coupling of primary alcohols with allyl-acetates, as described by Krische, to form chiral secondary homo-allylic alcohols were performed in parallel as a means to optimize the ee values thereof. Specifically, approximately 400 examples of this reaction were performed by varying the catalyst, added acids and bases, and starting reactants, to form 4-phenyl-1-butene-4-ol (1). The ee values for the transformations were determined in a high-throughput fashion using a 4-component assembly that creates a circular dichroism signal indicative of the extent of asymmetric induction. Further, a parallel and rapid quantitative TLC method measures the yield of each reaction, revealing which reactions give reliable ee values in the CD-based assay. Overall, the nearly 200 reactions whose ee values were determined could be quantitated in under two hours. Using a combination of the TLC method to measure yield with the CD-assay to measure ee values, several trends in reaction conditions were revealed. For example, it was found that the cyclometallated iridium catalyst modified by BINAP and m-nitro-p-cyano-benzoic acid delivered adduct 1 with the highest levels of enantiomeric enrichment (94%), whereas the corresponding SEGPHOS-modified catalyst gave a comparable yield but lower ee (91%). Most importantly, this study shows that supramolecular assemblies can report hundreds of ee values in a rapid and reliable fashion to analyze parallel synthesis routines.

  11. Diffusion of cosmic rays at EeV energies in inhomogeneous extragalactic magnetic fields

    Ultra-high energy cosmic rays can propagate diffusively in cosmic magnetic fields. When their propagation time is comparable to the age of the universe, a suppression in the flux relative to the case in the absence of magnetic fields will occur. In this work we find an approximate parametrization for this suppression for energies below ∼ Z EeV using several magnetic field distributions obtained from cosmological simulations of the magnetized cosmic web. We assume that the magnetic fields have a Kolmogorov power spectrum with the field strengths distributed according to these simulations. We show that, if magnetic fields are coupled to the matter distribution, low field strengths will fill most of the volume, making the suppression milder compared to the case of a constant magnetic field with strength equal to the mean value of this distribution. We also derive upper limits for this suppression to occur for some models of extragalactic magnetic fields, as a function of the coherence length of these fields.

    A search for production of a new quark flavor in multihadronic states from e+e- annihilation has been made up to an energy of 35.8 GeV in the center of mass. No evidence is seen for such production. A new statistical analysis by the JADE collaboration of the combined data of four PETRA experiments from a fine energy scan in the region 29.90 to 31.46 GeV in the center of mass sets new upper limits on the integrated cross section for a bound state consisting of a new flavor quark and antiquark. The ability of the JADE detector to measure dE/dx provides new upper bounds on the production of fractionally charged particles such as free quarks, or of heavy, integrally charged states such as long-lived B mesons. Finally the fractions of the final state energy carried by gamma rays and by neutral particles of all kinds are measured at center of mass energies from 12 to 35 GeV. The gamma ray and neutral energy fractions are approximately 26% and 38% respectively, while the fractional energy carried by neutrinos is less than 15%.

    Under the authorization provided by Section 634 of the Energy Independence and Security Act of 2007 (P.L. 110-140), in 2009 FAU was awarded U.S. Congressionally Directed Program (CDP) funding through the U.S. Department of Energy (DOE) to investigate and develop technologies to harness the energy of the Florida Current as a source of clean, renewable, base-load power for Florida and the U.S. A second CDP award in 2010 provided additional funding in order to enhance and extend FAU’s activities. These two CDPs in 2009 and 2010 were combined into a single DOE grant, DE-EE0000319, and are the subject of this report. Subsequently, in July 2010 funding was made available under a separate contract, DE-EE0004200. Under that funding, DOE’s Wind and Water Power Program designated FAU’s state of Florida marine renewable energy (MRE) center as the Southeast National Marine Renewable Energy Center (SNMREC). This report discusses SNMREC activities funded by the DE-EE0000319 grant, but will make reference, as appropriate, to activities that require further investigation under the follow-on grant. The concept of extracting energy from the motions of the oceans has a long history. However, implementation on large scales of the technologies to effect renewable energy recovery from waves, tides, and open-ocean currents is relatively recent. DOE’s establishment of SNMREC recognizes a significant potential for ocean current energy recovery associated with the (relatively) high-speed Florida Current, the reach of the Gulf Stream System flowing through the Straits of Florida, between the Florida Peninsula and the Bahamas Archipelago. The proximity of the very large electrical load center of southeast Florida’s metropolitan area to the resource itself makes this potential all the more attractive. As attractive as this potential energy source is, it is not without its challenges. Although the technology is conceptually simple, its design and implementation in a commercially

    In this work, we consider the process e++e-→b b ¯ + ET, at the future electron-positron colliders such as the International Linear Collider and Compact Linear Collider, to look for the dark matter (DM) effect and identify its nature at two different center-of-mass energies Ec .m .=500 GeV and 1 TeV. For this purpose, we take two extensions of the standard model, in which the DM could be a real scalar or a heavy right-handed neutrino (RHN) similar to many models motivated by neutrino mass. In the latter extension, the charged leptons are coupled to the RHNs via a lepton flavor violating interaction that involves a charged singlet scalar. After discussing different constraints, we define a set of kinematical cuts that suppress the background and generate different distributions that are useful in identifying the DM nature. The use of polarized beams (like the polarization P (e-,e+)=[+0.8 ,-0.3 ] at the International Linear Collider) makes the signal detection easier and the DM identification more clear, where the statistical significance gets enhanced by twice (five times) for scalar (RHN) DM.

    A flux of neutrons from an astrophysical source in the Galaxy can be detected in the Pierre Auger Observatory as an excess of cosmic-ray air showers arriving from the direction of the source. To avoid the statistical penalty for making many trials, classes of objects are tested in combinations as nine "target sets," in addition to the search for a neutron flux from the Galactic center or from the Galactic plane. Within a target set, each candidate source is weighted in proportion to its electromagnetic flux, its exposure to the Auger Observatory, and its flux attenuation factor due to neutron decay. These searches do not find evidence for a neutron flux from any class of candidate sources. Tabulated results give the combined p-value for each class, with and without the weights, and also the flux upper limit for the most significant candidate source within each class. These limits on fluxes of neutrons significantly constrain models of EeV proton emission from non-transient discrete sources in the Galaxy.

    The new tracking system of the Spherical Neutral Detector for experiments at the VEPP-2000 e+e- collider in Novosibirsk is described. The system consists of a 9-layer drift chamber with 24 jet cells and a proportional chamber in a common gas volume. Main system features are its small size and high density of readout channels for gaseous tracking systems at colliding experiments. The drift chamber provides at least four measurements along the track for charged particles within 94% solid angle and nine measurements for particles propagating at large angle relative to the beam axis. R-ϕ coordinates (in a plane perpendicular to the beam axis) are obtained using the ionization drift time measurement. Longitudial coordinates are measured using charge division on anode wires and charge distribution on cathode strips. Design angular resolutions for radial tracks are σϕ=0.26∘, σθ=0.3∘, the vertex resolution is σR=0.2 mm. The full-size prototype of the tracking system has been assembled and tested. The wire structure of the prototype represents one quadrant of the chamber. Results of the prototype assembly quality control and tests with radioactive sources and cosmic rays are presented. They are in a good agreement with expected system parameters.

    We present an analysis of the preliminary experimental data of direct J/ψ production in e+e- processes at low energies. We find that the color-octet contributions are crucially important to the cross section in this energy region, and their inclusion produces a good description of the data. By fitting to the data, we extract the individual values of two color-octet matrix elements: ~1.1×10-2 GeV3; /m2c~7.4×10-3 GeV3. We discuss the allowed range of the two matrix elements constrained by the theoretical uncertainties. We find that is poorly determined because it is sensitive to the variation of the choice of mc, αs and . However, /m2c is quite stable [about (6-9)×10-3 GeV3] when the parameters vary in reasonable ranges. The uncertainties due to large experimental errors are also discussed.

    The mass of the W boson is determined from the direct reconstruction of W decays in WW→qq¯qq¯ and WW→ℓνqq¯ events in e+e- collisions at LEP. The data sample corresponds to an integrated luminosity of 683 pb-1 collected with the ALEPH detector at centre-of-mass energies up to 209 GeV. To minimise any effect from colour reconnection a new procedure is adopted in which low energy particles are not considered in the mass determination from the qq¯qq¯ channel. The combined result from all channels is m_{text{W}}=80.440 ±0.043{text{(stat.)}} ±0.024{text{(syst.)}} ±0.009{text{(FSI)}} ±0.009{text{(LEP)}} text{GeV/}c^2, where FSI represents the possible effects of final state interactions in the qq¯qq¯ channel and LEP indicates the uncertainty in the beam energy. From two-parameter fits to the W mass and width, the W width is found to be Γ_{text{W}} = 2.14 ±0.09{text{(stat.)}} ±0.04{text{(syst.)}} ±0.05{text{(FSI)}} ±0.01{text{(LEP)}} text{GeV}.

    The FCC-e+e- injector complex needs to produce and to transport a high-intensity e+/e- beam at a fast repetition rate of about 0.1 Hz for topping up the collider at its collision energy. A basic parameter set exists for all the collider energies, assuming a 10 GeV linac operating with a large number of bunches being accumulated in the existing SPS, which serves as pre-accelerator and damping ring before the bunches are transferred to the high-energy booster. The purpose of this study is to provide the conceptual design of an alternative accelerator ring, replacing the SPS in the present scheme. This ring will have injection energy of 6 GeV and extraction energy of 20 GeV. In this study, the basic parameters of the ring are established, including the optics design and layout. Preliminary consideration for non-linear dynamics optimization and the impact of intra beam scattering are also presented.

  20. A new technique for the observation of EeV and ZeV cosmic rays

    NASA Astrophysics Data System (ADS)

    Kieda, D. B.

    1995-12-01

    We describe a new technique tor the detection of EeV (10 18 eV) and ZeV (10 21 eV) cosmic rays in the atmosphere. The technique uses the fact that the Čerenkov light emitted by atmospheric extensive showers generated by primaries in this energy range is brighter than the fluctuations in the ambient light of the night sky, even with a full moon present. The Cerenkov light is also brighter than fluctuations in the twilight sky, and can even be of similar size as fluctuations in direct sunlight. For the highest energy cosmic rays ( E > 1 ZeV), this may allow optical detection with on-time efficiency limited only by the weather. The energy, angular, and Xmax resolution of the technique is examined as a function of the background day and night sky conditions. Using a "shadowing" method for determining the direction of the original cosmic ray primary, angular resolution between 0.3° to - 3 ° is possible, depending upon the zenith angle and energy of the primary, and the amount of background light. This resolution is equal to or better than the expected angular resolution obtained through the usual timing techniques. The technique gives an energy resolution 3% < ΔE/E < 40%, and X max resolution 18 g cm -2 < δ X max < 70 g cm -2, dependent upon primary energy, zenith angle, and sky conditions.

    The lepton identification is essential for the physics programs at high-energy frontier, especially for the precise measurement of the Higgs boson. For this purpose, a toolkit for multivariate data analysis (TMVA) based lepton identification (LICH) has been developed for detectors using high granularity calorimeters. Using the conceptual detector geometry for the Circular Electron-Positron Collider (CEPC) and single charged particle samples with energy larger than 2 GeV, LICH identifies electrons/muons with efficiencies higher than 99.5% and controls the mis-identification rate of hadron to muons/electrons to better than 1/0.5%. Reducing the calorimeter granularity by 1-2 orders of magnitude, the lepton identification performance is stable for particles with E > 2 GeV. Applied to fully simulated eeH/μ μ H events, the lepton identification performance is consistent with the single particle case: the efficiency of identifying all the high energy leptons in an event, is 95.5-98.5%.

    Evidence of the negative effects of several pharmaceutical molecules, such as hormones and steroids, on the environment can be observed throughout the world. This paper presents the results of the anodic oxidation of the mixture of gestodene steroid hormones and 17 α-ethinylestradiol present in aqueous medium. The tests were conducted in an undivided cell containing a working volume of 50 mL, using a Na2SO4 solution as support electrolyte and boron-doped diamond electrodes. The experiments were adjusted to the structure of a 3(3) factorial design. The evaluated factors were: support electrolyte concentration (0.02, 0.05, and 0.10 M), pH of the reaction media (2, 3, and 4), and current density (16, 32, and 48 mA cm(-2)). Under the optimum conditions (0.02 M Na2SO4, pH 4, and current density of 32 mA cm(-2)), the degradation of at least 93% of the initial concentration of gestodene and 17α-ethinylestradiol was reached in a reaction time of 5 and 10 min, respectively. The complete degradation of both molecules required 15 min of reaction. Under these conditions, the degradation profile of the pharmaceutical mixture as each one of the active ingredients, followed a pseudo-first order kinetic behavior (kmix = 0.0321, kGES = 0.4206, and kEE2 = 0.3209 min(-1)).

    The process e+e- →K+K-π+π- has been studied in the center-of-mass energy range from 1500 to 2000 MeV using a data sample of 23 pb-1 collected with the CMD-3 detector at the VEPP-2000 e+e- collider. Using about 24 000 selected events, the e+e- →K+K-π+π- cross section has been measured with a systematic uncertainty decreasing from 11.7% at 1500-1600 MeV to 6.1% above 1800 MeV. A preliminary study of K+K-π+π- production dynamics has been performed.

    We report the first observation of e(+)e(-) annihilation into states of positive C parity, namely, rho(0)rho(0) and phirho(0). The two states are observed in the pi(+)pi(-)pi(+)pi(-) and K(+)K(-)pi(+)pi(-) final states, respectively, in a data sample of 225 fb(-1) collected by the BABAR experiment at the Positron-Electron Project II e(+)e(-) storage rings at energies near sqrt[s]=10.58 GeV. The distributions of costheta(*), where theta(*) is the center-of-mass polar angle of the phi meson or the forward rho(0) meson, suggest production by two-virtual-photon annihilation. We measure cross sections within the range |costheta(*)|<0.8 of sigma(e(+)e(-)-->rho(0)rho(0))=20.7+/-0.7(stat)+/-2.7(syst) fb and sigma(e(+)e(-)-->phirho(0))=5.7+/-0.5(stat)+/-0.8(syst) fb.

    Reactor neutrino experiments build large-scale detector systems to detect neutrinos. In liquid scintillator, a neutral bound state of a positron and an electron, named positronium, can be formed. The spin triplet state is called ortho-positronium (o-Ps). In this article, an experiment is designed to measure the lifetime of o-Ps, giving a result of 3.1 ns. A PSD parameter based on photon emission time distribution (PETD) was constructed to discriminate e+/e-. Finally, the application of e+/e- discrimination in the JUNO experiment is shown. It helps suppress 8He/9Li backgrounds and improves the sensitivity by 0.6 in χ 2 analysis with an assumption of σ = 1 ns PMT Transit Time Spread, which will bring a smearing effect to the PETD.

  8. Coulomb effects in high-energy e+e- electroproduction by a heavy charged particles in an atomic field

    Krachkov, P. A.; Milstein, A. I.

    2017-08-01

    The cross section of high-energy e+e- pair production by a heavy charged particle in the atomic field is investigated in detail. We take into account the interaction with the atomic field of e+e- pair and a heavy particle as well. The calculation is performed exactly in the parameters of the atomic field. It is shown that, in contrast to the commonly accepted point of view, the cross section differential with respect to the final momentum of a heavy particle is strongly affected by the interaction of a heavy particle with the atomic field. However, the cross section integrated over the final momentum of a heavy particle is independent of this interaction.

    We compute the expected yields of protons and Λ's in e+e- annihilation, using the Konishi-Ukawa-Veneziano jet calculus and the recombination model. Our results have many features in common with the data, including their approximate size. We derive a differential equation for baryon production, and show that the terms we have calculated are one of three physically different contributions.

    Metzger, W. J.; Novák, T.; Csörgő, T.; Kittel, W.

    A short review of Bose-Einstein correlations in hadronic e+e- annihilation is presented. Bose-Einstein correlations of pairs of identical charged pions in hadronic Z-boson decays are analyzed in terms of various parametrizations. A good description is achieved using a Lévy stable distribution in conjunction with a hadronization model having highly correlated configuration and momentum space, the τ-model. Using these results, the source function is reconstructed.

    Petrologic, geochemical, and structural analyses of cores and cuttings obtained from 3000 to 4389-m true vertical depth in drill hole EE-2 indicate that this deeper part of the Precambrian section at Fenton Hill, New Mexico is composed primarily of a very heterogeneous and structurally anisotropic metamorphic complex, locally intruded by dikes and sills of granodioritic and monzogranitic composition. In this borehole none of these igneous bodies approach in size the 335-m-thick biotite-granodiorite body encountered at 2591-m depth beneath Fenton Hill in the other two drill holes. Contacts between the igneous and metamorphic rocks range from sharp and discordant to gradational. Analysis of cuttings indicates that clay-rich alteration zones are relatively common in the openhole portion of EE-2. These zones average about 20 m in thickness. Fracture sets in the Precambrian basement rock intersected by the EE-2 well bore mostly trend northeast and are steeply dipping to vertical; however, one of the sets dips gently to the northwest. Slickensided fault planes are present in a core (No.5) taken from a true vertical depth of 4195 m. Available core orientation data and geologic inference suggest that the faults dip steeply and trend between N.42/sup 0/ and 59/sup 0/E.

    Methanol extracts of various plant parts of Ailanthus altissima were tested against the root knot nematode Meloidogyne javanica . Extracts of bark (ABE), wood (AWE), roots (ARE), and leaves (ALE) from A. altissima were investigated against freshly hatched second-stage juveniles (J(2)). AWE was the most active extract, with EC(50/3d) of 58.9 mg/L, while ALE, ARE, and ABE did not show nematicidal activity. The chemical composition of the extracts of A. altissima was determined by gas chromatography-mass spectrometry, and (E,E)-2,4-decadienal, (E)-2-undecenal, (E)-2-decenal, hexanal, nonanal, and furfural were the most prominent constituents. (E,E)-2,4-Decadienal, (E)-2-decenal, and furfural showed the highest nematicidal activity against M. javanica , with EC(50/1d) = 11.7, 20.43, and 21.79 mg/L, respectively, while the other compounds were inactive at the concentrations tested. The results obtained showed that AWE and its constituents (E,E)-2,4-decadienal and (E)-2-decenal could be considered as potent botanical nematicidal agents.

    2016-04-01

    For the search for additional Higgs bosons in the Minimal Supersymmetric Standard Model (MSSM) as well as for future precision analyses in the Higgs sector precise knowledge of their production properties is mandatory. We evaluate the cross sections for the neutral Higgs boson production at e^+e^- colliders in the MSSM with complex parameters (cMSSM). The evaluation is based on a full one-loop calculation of the production mechanism e^+e^- → h_i Z, h_i γ , h_i h_j (i,j = 1,2,3), including soft and hard QED radiation. The dependence of the Higgs boson production cross sections on the relevant cMSSM parameters is analyzed numerically. We find sizable contributions to many cross sections. They are, depending on the production channel, roughly of 10-20 % of the tree-level results, but can go up to 50 % or higher. The full one-loop contributions are important for a future linear e^+e^- collider such as the ILC or CLIC. There are plans to implement the evaluation of the Higgs boson production cross sections into the code FeynHiggs.

    The shape of jets produced in (quasi-) real photon-photon collisions as well as in e+e- annihilation process has been studied with a cone jet finding algorithm, using the data taken with the TOPAZ detector at the TRISTAN e+e- collider at an average center-of-mass energy (see) of 58 GeV. The results are presented in terms of the jet width as a function of the jet transverse energy (ETjet) as well as a scaled transverse jet energy, xT (=2ETjet/sqrt(s)). The jet width narrows as EjetT increases; however, at the same value of ETjet the jet width in γγ collisions at TRISTAN is significantly narrower than that in γp collisions at HERA. By comparing our results with the data in other reactions, it has been shown that the jet width in γγ, γp, pp¯ collisions as well as the e+e- annihilation process has an approximate scaling behavior as a function of xT.

  16. Weibel instability for a streaming electron, counterstreaming e-e, and e-p plasmas with intrinsic temperature anisotropy

    The existence of Weibel instability for a streaming electron, counterstreaming electron-electron (e-e), and electron-positron (e-p) plasmas with intrinsic temperature anisotropy is investigated. The temperature anisotropy is included in the directions perpendicular and parallel to the streaming direction. It is shown that the beam mean speed changes the instability mode, for a streaming electron beam, from the classic Weibel to the Weibel-like mode. The analytical and numerical solutions approved that Weibel-like modes are excited for both counterstreaming e-e and e-p plasmas. The growth rates of the instabilities in e-e and e-p plasmas are compared. The growth rate is larger for e-p plasmas if the thermal anisotropy is small and the opposite is true for large thermal anisotropies. The analytical and numerical solutions are in good agreement only in the small parallel temperature and wave number limits, when the instability growth rate increases linearly with normalized wave number kc∕ω{sub p}.

  17. Production du baryon Sigma+ dans les collisions e+e- au LEP

    Joly, Andre

    Les mécanismes de production des baryons dans les interactions e+e- font l'objet de nombreuses études. De plus, les modes de production des baryons étranges semblent faire appel A des processus spécifiques, qui sont encore mal compris. Notre étude de la production des baryons Σ+ dans les interactions e+e- nous permet de formuler certaines remarques sur l'état des connaîssances acquises sur le sujet. Une methode de reconstruction originale et des critères de sélection spécifiques ont été développés afin d'identifier des baryons Σ+ de haute Energie ( ES+ > 5 GeV), partir de leur canal de désintégration en un proton et un π0 (S+-->p+p0 ). Trois mesures principales sont réalisées à partir de notre échantillon de baryons reconstruits.

    will be protective of human health and the environment. Decommissioning the TAN-607 Hot Shop Area is consistent with the joint DOE and U.S. Environmental Protection Agency (EPA) Policy on Decommissioning of Department of Energy Facilities Under the Comprehensive Environmental Response, Compensation and Liability Act, which establishes the CERCLA NTCRA process as the preferred approach for decommissioning surplus DOE facilities. Under this policy, a NTCRA may be taken when DOE determines that the action will prevent, minimize, stabilize, or eliminate a risk to human health and/or the environment. When DOE determines that a CERCLA NTCRA is necessary, DOE is authorized to evaluate, select, and implement the removal action that DOE determines is most appropriate to address the potential risk posed by the release or threat of release. This action is taken in accordance with applicable authorities and in conjunction with EPA and the State of Idaho pursuant to Section 5.3 of the Federal Facility Agreement and Consent Order. In keeping with the joint policy, this engineering evaluation/cost analysis (EE/CA) was developed in accordance with CERCLA as amended by the ''Superfund Amendments and Reauthorization Act of 1986'' and in accordance with the ''National Oil and Hazardous Substances Pollution Contingency Plan.'' This EE/CA is consistent with the remedial action objectives (RAOs) of the Final Record of Decision, Test Area North, Operable Unit 1-10 and supports the overall remediation goals established through the Federal Facility Agreement and Consent Order for Waste Area Group 1. Waste Area Group 1 is located at TAN.

    We study the Z H associated production followed by the Higgs H →γ γ ¯ decay into a photon plus an invisible and massless dark photon, at future high-energy e+e- facilities. Large H →γ γ ¯ decay rates (with branching ratios up to a few percent) are allowed, thanks to possible nondecoupling properties of the Higgs boson under specific conditions, and unsuppressed dark-photon couplings in the dark sector. Such large decay rates can be obtained in the framework of recent flavor models that aim to naturally explain the observed spread in the fermion mass spectrum. We analyze the experimental prospects for observing the e+e-→Z H process followed by the semi-invisible Higgs decay into a photon plus a massless invisible system. Search strategies for both the leptonic and the hadronic final states (arising from Z →μ+μ- and Z →q q ¯, respectively) are outlined. We find that a 5 σ sensitivity to a branching fraction B Rγ γ ¯˜3 ×10-4 can be achieved by combining the two channels with an integrated luminosity of 10 ab-1 at a c.m. energy of 240 GeV. This is considerably better than the corresponding sensitivity in alternative channels previously studied at lepton colliders. The analysis is model independent, and its results can be straightforwardly applied to the search for any Higgs two-body decay into a photon plus an undetected light particle.

    The longitudinal and transverse response functions for the inclusive quasielastic (e,e') reaction are analyzed in detail. A microscopic theoretical framework for the many-body reaction provides a clear conceptual (nonrelativistic) basis for treating final state interactions and goes far beyond simple wave or Hermitean potential models. The many-body physics of inelastic final state channels as described by optical and multiple scattering theories included by incorporating a full complex optical potential. Explicit nonrelativistic and relativistic momentum-space calculations quantitatively demonstrate the importance of such a treatment of final state interactions for both the transverse and longitudinal response. Nonrelativistic calculations are performed using final state interactions based on phenomenology, local density models and microscopic multiple scattering theory. Relativistic calculations span a similar range of models and employ Dirac bound state wave functions. The theoretical extension to relativistic dynamics is of course not clear, but is done in obvious parallel to elastic proton scattering. Extensive calculations are performed for UCa at momentum transfers of 410, 550 and 700 MeV/c. A number of interesting physical effects are observed, including significant relativistic suppressions (especially for R/sub L/), large-off-shell and virtual pair effects, enhancement of the tails of the response by the final state interactions, and large qualitative and even shape distinctions between the predictions of the various models of the final state interactions. None of the models is found to be able to simultaneously predict the data for both response functions. This strongly suggests that additional physical mechanisms are of qualitative importance in inclusive quasielastic electron scattering. 48 refs., 16 figs.

    Genistein and ethinyl estradiol (EE2) were examined in multigenerational reproductive and chronic toxicity studies that had different treatment intervals among generations. Sprague-Dawley rats received genistein (0, 5, 100, or 500 ppm) or EE2 (0, 2, 10, or 50 ppb) in a low phytoestrogen diet. Nonneoplastic effects in females are summarized here. Genistein at 500 ppm and EE2 at 50 ppb produced similar effects in continuously exposed rats, including decreased body weights, accelerated vaginal opening, and altered estrous cycles in young animals. At the high dose, anogenital distance was subtly affected by both compounds, and a reduction in litter size was evident in genistein-treated animals. Genistein at 500 ppm induced an early onset of aberrant cycles relative to controls in the chronic studies. EE2 significantly increased the incidence of uterine lesions (atypical focal hyperplasia and squamous metaplasia). These compound-specific effects appeared to be enhanced in the offspring of prior exposed generations. PMID:19159674

    Preparative chemical methods for the synthesis of eight oxidative transformation products of ethinyl estradiol (EE) and norethindrone acetate (NA) are described. The prepared materials are useful as reference materials and standards for pharmaceutical analysis of EE and NA as bulk chemical or in formulated product. All eight products result from oxidation of the A and/or B rings of the parent compounds. Oxidation of the heteroannular 3,5 dienyl acetate derivative of NA resulted in the 6 alpha-hydroxy, 6 beta-hydroxy and 6-keto NA. Oxidation of 6-keto NA led to the preparation of 6 alpha-hydroxy, 6 beta-hydroxy, 6-keto- and Delta(6) EE. Delta(11) EE was prepared from estrone.

    Aggressive behavior is crucial for maintaining social hierarchy in anemonefish. Endocrine disrupting chemicals such as EE2 may affect fish social hierarchy via disrupting their aggression. In this study, we aimed to characterize the effects of 17α-ethinylestradiol (EE2) on aggressive behavior and social hierarchy in the false clown anemonefish (Amphiprion ocellaris). In the laboratory experiment, juvenile anemonefish were randomly distributed to separated tanks to form small colonies of three individuals and were fed with EE2-dosed diet (100ng/g food) or a control diet for 90d. Through the experiment, each tank was videotaped and behavioral indicators of social status, including aggressive behavior, submissive response, and shelter utilization, were quantitatively analyzed from the videos. The EE2 exposure caused a higher frequency of intra-colonial aggressive interactions and a less stable social hierarchy. Our findings demonstrate the importance of examining the effects of endocrine disrupting chemicals on the social behavior of coral reef fish.

    A beam optics scheme has been designed for the future circular collider-e+e- (FCC-ee). The main characteristics of the design are: beam energy 45 to 175 GeV, 100 km circumference with two interaction points (IPs) per ring, horizontal crossing angle of 30 mrad at the IP and the crab-waist scheme [P. Raimondi, D. Shatilov, and M. Zobov, arXiv:physics/0702033; P. Raimondi, M. Zobov, and D. Shatilov, in Proceedings of the 22nd Particle Accelerator Conference, PAC-2007, Albuquerque, NM (IEEE, New York, 2007), p. TUPAN037.] with local chromaticity correction. The crab-waist scheme is implemented within the local chromaticity correction system without additional sextupoles, by reducing the strength of one of the two sextupoles for vertical chromatic correction at each side of the IP. So-called "tapering" of the magnets is applied, which scales all fields of the magnets according to the local beam energy to compensate for the effect of synchrotron radiation (SR) loss along the ring. An asymmetric layout near the interaction region reduces the critical energy of SR photons on the incoming side of the IP to values below 100 keV, while matching the geometry to the beam line of the FCC proton collider (FCC-hh) [A. Chancé et al., Proceedings of IPAC'16, 9-13 May 2016, Busan, Korea, TUPMW020 (2016).] as closely as possible. Sufficient transverse/longitudinal dynamic aperture (DA) has been obtained, including major dynamical effects, to assure an adequate beam lifetime in the presence of beamstrahlung and top-up injection. In particular, a momentum acceptance larger than ±2 % has been obtained, which is better than the momentum acceptance of typical collider rings by about a factor of 2. The effects of the detector solenoids including their compensation elements are taken into account as well as synchrotron radiation in all magnets. The optics presented in this paper is a step toward a full conceptual design for the collider. A number of issues have been identified for further

  11. Measuring the Higgs-vector boson couplings at linear e+e- collider

    2008-12-01

    We estimate the accuracy with which the coefficient of the CP even dimension-six operators involving Higgs and two vector bosons (HVV) can be measured at linear e+e- colliders. Using the optimal observables method for the kinematic distributions, our analysis is based on the five different processes. First is the WW fusion process in the t-channel (e+e-→ν¯eνeH), where we use the rapidity y and the transverse momentum pT of the Higgs boson as observables. Second is the ZH pair production process in the s channel, where we use the scattering angle of the Z and the Z decay angular distributions, reproducing the results of the previous studies. Third is the t-channel ZZ, fusion processes (e+e-→e+e-H), where we use the energy and angular distributions of the tagged e+ and e-. In the fourth, we consider the rapidity distribution of the untagged e+e-H events, which can be approximated well as the γγ fusion of the bremsstrahlung photons from e+ and e- beams. As the last process, we consider the single-tagged e+e-H events, which probe the γe±→He± process. All the results are presented in such a way that statistical errors of the constraints on the effective couplings and their correlations are read off when all of them are allowed to vary simultaneously, for each of the above processes, for mH=120GeV, at s=250GeV, 350 GeV, 500 GeV, and 1 TeV, with and without e- beam polarization of 80%. We find, for instance, that the HZZ and HWW couplings can be measured with 0.6% and 0.9% accuracy, respectively, for the integrated luminosity of L=100fb-1 at s=250GeV, 350 GeV, and L=500fb-1 at s=500GeV, 1 TeV, for the luminosity uncertainty of 1% at each energy. We find that the luminosity uncertainty affects only one combination of the nonstandard couplings, which are proportional to the standard HWW and HZZ couplings, while it does not affect the errors of the other independent combinations of the couplings. As a consequence, we observe that a few combinations of the eight

    We describe an experiment to search for a new vector boson A' with weak coupling alpha' > 6 x 10–8 α to electrons (α' = e2/4π) in the mass range 65 MeV < mA' < 550 MeV. New vector bosons with such small couplings arise naturally from a small kinetic mixing of the "dark photon" A' with the photon -- one of the very few ways in which new forces can couple to the Standard Model -- and have received considerable attention as an explanation of various dark matter related anomalies. A' bosons are produced by radiation off an electronmore » beam, and could appear as narrow resonances with small production cross-section in the trident e+e- spectrum. We summarize the experimental approach described in a proposal submitted to Jefferson Laboratory's PAC35, PR-10-009. This experiment, the A' Experiment (APEX), uses the electron beam of the Continuous Electron Beam Accelerator Facility at Jefferson Laboratory (CEBAF) at energies of ~1-4 GeV incident on 0.5-10% radiation length Tungsten wire mesh targets, and measures the resulting e+e- pairs to search for the A' using the High Resolution Spectrometer and the septum magnet in Hall A. With a ~1 month run, APEX will achieve very good sensitivity because the statistics of e+e- pairs will be ~10,000 times larger in the explored mass range than any previous search for the A' boson. These statistics and the excellent mass resolution of the spectrometers allow sensitivity to α'/α one to three orders of magnitude below current limits, in a region of parameter space of great theoretical and phenomenological interest. Similar experiments could also be performed at other facilities, such as the Mainz Microtron.« less

    We have measured the azimuthal correlation of hadrons produced in e+e- annihilations at √s =58 GeV. In perturbative QCD these correlations are sensitive to the interference between soft gluons emitted at large angles with respect to the event axis. However, Monte carlo calculations incorporating QCD-inspired hadronization models in which the correlation of interjet particles is treated in a phenomenological manner describe the data well. We also observe that angular ordering of the parton showering in the lund Monte Carlo program improves the agreement with the data.

    TheWASA-at-COSY experiment is, besides meson production processes, dedicated to studies on rare and forbidden decays of light mesons. In extensive η-production beam times, a high-statistics data set have been collected by means of proton-proton scattering which opens the door to studies on forbidden decays like the C-parity violating process η → π0e+e-. In this article, an optimized detector calibration leading to a significantly improved missing mass resolution and a preliminary decay analysis are presented.

    Glioblastoma multiforme (GBM) is the most fatal form of human brain cancer. Although temozolomide (TMZ), an oral alkylating chemotherapeutic agent, improves the survival rate, the prognosis of patients with GBM remains poor. Naturally occurring carbazole alkaloids isolated from curry leaves (Murraya koenigii Spreng.) have been shown to possess a wide range of anticancer properties. However, the effects of carbazole derivatives on glioblastoma cells remain poorly understood. In the present study, anti-glioblastoma profiles of a series of synthetic carbazole derivatives were evaluated in vitro. The most promising derivative in this series was BC3EE2,9B, which showed significant anti-proliferative effects in GBM8401 and GBM8901 cells. BC3EE2,9B also triggered cell-cycle arrest, most prominently at the G1 stage, and suppressed glioblastoma cell invasion and migration. Furthermore, BC3EE2,9B induced autophagy-mediated cell death and synergistically sensitized GBM cells to TMZ cytotoxicity. The possible mechanism underlying BC3EE2,9B-induced autophagy may involve activation of adenosine monophosphate-activated protein kinase and the attenuation of the Akt and mammalian target of the rapamycin downstream signaling pathway. Taken together, the present results provide molecular evidence for the mode of action governing the ability of BC3EE2,9B to sensitize drug-resistant glioblastoma cells to the chemotherapeutic agent TMZ.

    Transition form factors γ* → γf2 (1270) and γ* → γa2 (1320) and corresponding e+e- → γ* → f2γ and e+e- → γ* → a2γ cross sections are considered up to high energies. It is shown that the QCD asymptotics of the amplitudes of the e+e- → γ* → f2γ and e+e- → γ* → a2γ reactions can be reached only by taking into account a compensation of contributions of ρ(770), ω(782) with contributions of their radial excitations. Recent BABAR measurement of the e+e- → f2γ → π+π-γ cross section at 10.58 GeV gives hope for detailed investigation of the γ*(s) → f2γ and γ*(s) → a2γ transition form factors at high energy region. Recent Belle data on the γ*(Q2)γ → f2 transition up to Q2 = 30 GeV2 are taken into account.

    We explore the discovery prospects for B{sup '}B{sup '} pair production followed by direct decays B{sup '}{yields}bX, where B{sup '} is a new quark and X is a long-lived neutral particle. We develop optimized cuts in the (m{sub B}{sup '},m{sub X}) plane and show that the 7 TeV LHC with an integrated luminosity of 1(10) fb{sup -1} may exclude masses up to m{sub B}{sup '}{approx}620(800) GeV, completely covering the mass range allowed for new quarks that get mass from electroweak symmetry breaking. This analysis is applicable to other models with bbEe{sub T} signals, including supersymmetric models with bottom squarks decaying directly to neutralinos, and models with exotic quarks decaying directly to GeV-scale dark matter. To accommodate these and other interpretations, we also present model-independent results for the bbEe{sub T} cross section required for exclusion and discovery.

    With the increasing maturity of distributed object technology, CORBA, .NET and EJB are universally used in traditional IT field. However, theories and practices of distributed spatial database need farther improvement in virtue of contradictions between large scale spatial data and limited network bandwidth or between transitory session and long transaction processing. Differences and trends among of CORBA, .NET and EJB are discussed in details, afterwards the concept, architecture and characteristic of distributed large-scale seamless spatial database system based on J2EE is provided, which contains GIS client application, web server, GIS application server and spatial data server.

    Discovery of unexpected properties of the Higgs boson offers an intriguing opportunity of shedding light on some of the most profound puzzles in particle physics. The Beyond Standard Model (BSM) decays of the Higgs boson could reveal new physics in a direct manner. Future electron-positron lepton colliders operating as Higgs factories, including CEPC, FCC-ee and ILC, with the advantages of a clean collider environment and large statistics, could greatly enhance the sensitivity in searching for these BSM decays. In this work, we perform a general study of Higgs exotic decays at future $e^+e^-$ lepton colliders, focusing on the Higgs decays with hadronic final states and/or missing energy, which are very challenging for the High-Luminosity program of the Large Hadron Collider (HL-LHC). We show that with simple selection cuts, $O(10^{-3}\\sim10^{-5})$ limits on the Higgs exotic decay branching fractions can be achieved using the leptonic decaying spectator $Z$ boson in the associated production mode $e^+e^-\\rightarrow Z H$. We further discuss the interplay between the detector performance and Higgs exotic decay, and other possibilities of exotic decays. Our work is a first step in a comprehensive study of Higgs exotic decays at future lepton colliders, which is a key ingredient of Higgs physics that deserves further investigation.

    We present a detailed analysis of multiple production of the lightest CP-even Higgs boson (h) of the minimal supersymmetric standard model (MSSM) at high-energy e+e- colliders. We consider the production of the heavier CP-even Higgs boson (H) via Higgs-strahlung e+e--->ZH, in association with the CP-odd Higgs boson (A) in e+e--->AH, or via the fusion mechanism e+e--->νeν¯eH, with H subsequently decaying through H-->hh, thereby resulting in a pair of lighter Higgs bosons (h) in the final state. These processes can enable one to measure the trilinear Higgs couplings λHhh and λhhh, which can be used to theoretically reconstruct the Higgs potential. We delineate the regions of the MSSM parameter space in which these trilinear Higgs couplings could be measured at a future e+e- collider. In our calculations, we include in detail the radiative corrections to the Higgs sector of the MSSM, especially the mixing in the squark sector.

    A detailed theoretical derivation of the cross sections of e+e- → e+e- and e+e- → μ + μ - around the J/ψ resonance is reported. The resonance and interference parts of the cross sections, related to J/ψ resonance parameters, are calculated. Higher-order corrections for vacuum polarization and initial-state radiation are considered. An arbitrary upper limit of radiative correction integration is involved. Full and simplified versions of analytic formulae are given with precision at the level of 0.1% and 0.2%, respectively. Moreover, the results obtained in the paper can be applied to the case of the ψ(3686) resonance.

    A precise measurement of the cross section of the process e(+)e(-) --> pi(+)pi(-)(gamma) from threshold to an energy of 3 GeV is obtained with the initial state radiation (ISR) method using 232 fb(-1) of data collected with the BABAR detector at e(+)e(-) center-of-mass energies near 10.6 GeV. The ISR luminosity is determined from a study of the leptonic process e(+)e(-) --> mu(+)mu(-)gamma(gamma). The leading-order hadronic contribution to the muon magnetic anomaly calculated using the pipi cross section measured from threshold to 1.8 GeV is (514.1 +/- 2.2(stat) +/- 3.1(syst)) x 10(-10).

    The spin structure of the process γγ → e+e- is theoretically investigated. It is shown that, if the primary photons are unpolarized, the final electron and positron are unpolarized as well but their spins are strongly correlated. For the final (e+e-) system, explicit expressions for the components of the correlation tensor are derived, and the relative fractions of singlet and triplet states are found. It is demonstrated that in the process γγ → e+e- one of the Bell-type incoherence inequalities for the correlation tensor components is always violated and, thus, spin correlations of the electron and positron in this process have the strongly pronounced quantum character. Analogous consideration can be wholly applied as well to the two-photon processes γγ → μ+μ- and γγ → τ+τ-, which become possible at considerably higher energies.

    Accurate assessment of pulmonary capillary wedge pressure (PCWP) is essential for physicians to effectively manage patients with acute decompensated heart failure. The ratio of early transmittal velocity to tissue Doppler mitral annular early diastolic velocity (E/E') is used to estimate PCWP noninvasively in a wide range of cardiac patients. However, it remains contentious as to whether mitral E/E' is a reliable predictor of PCWP. In the present study, acute heart failure patients were divided into two groups on the basis of left ventricular (LV) systolic function: those with preserved ejection fraction (HFpEF) and those with reduced ejection fraction (HFrEF). The usefulness of mitral E/E' in estimating PCWP was compared between the two groups. Fifty consecutive patients who were admitted with acute decompensated heart failure and underwent both right-sided cardiac catheterization and transthoracic echocardiography during hospitalization were analyzed retrospectively. Pearson's correlation was used to evaluate associations between Doppler parameters and PCWP. E/E' was positively correlated with PCWP (r = 0.56, P = 0.01) in the heart failure with preserved ejection fraction group. However, no significant relationship was observed between PCWP and mitral E/E' (P = 0.85) in the heart failure with reduced ejection fraction group. There were no significant correlations between any of the conventional parameters considered (LVEF, left atrial dimension, E/A, IVRT, and DT) with PCWP in either group. In conclusion, mitral E/E' is useful for estimating PCWP in patients with acute heart failure with preserved ejection fraction but may not in those with reduced ejection fraction.

    Fish are more sensitive to introduced disturbances from synthetic endocrine disrupting compounds during early life phases compared with mature stages. 17α-Ethinylestradiol (EE2), which is the active compound in human oral contraceptives and hormone replacement therapies, is today ever present in the effluents from sewage treatment plants. EE2 targets and interacts with the endogenous biological systems of exposed vertebrates resulting in to large extents unknown short- and long-term effects. We investigated how EE2 exposure affects expression profiles of a large number of target genes during early life of roach (Rutilus rutilus). We exposed fertilized roach eggs collected from a lake in Southern Sweden to EE2 for 12weeks together with 1+-year-old roach in aquaria. We measured the gene expression of the estrogen receptor (esr)1/2a/2b, androgen receptor (ar), vitellogenin, cytochrome P450 (cyp)19a1a/1b in fertilized eggs; newly hatched larvae; 12-week-old fry; and juvenile wild roach (1+-year-old). Results shows that an EE2 concentration as low as 0.5ng/L significantly affects gene expression during early development. Gene expression responses vary both among life stages and molecular receptors. We also show that the gene profile of the estrogen feedback cycle to a large extent depends on the relationship between the three esr genes and the two cyp19a1 genes, which are all up-regulated with age. Results indicate that a disruption of the natural activity of the dominant esr gene could lead to detrimental biological effects if EE2 exposure occurs during development, even if this exposure occurred for only a short period.

    Estrogenic substances, including the contraceptive pharmaceutical 17α-ethinylestradiol (EE2), pose a threat to aquatic wildlife causing endocrine disturbances of physiological processes and reproductive behavior. We have previously demonstrated that the reproductive behavior of male zebrafish, Danio rerio, remain intact after lifelong exposure to low concentrations of EE2 (0.05 and 0.5ngL(-1)), concentrations high enough to cause morphological alterations of the male phenotype. Despite normal courtship behavior, the reproductive output is suppressed when these males were paired with unexposed females. In this study, we include the female courtship behavior in the analyzes of EE2's effects on behavior. Groups of male zebrafish were exposed to nominally 0, 1, 3 and 10ngL(-1) of EE2 from hatching to adulthood and subsequently individually paired with an unexposed female. Eleven distinct elements of the reproductive behavior were then extracted and analyzed using an automated video tracking system. Subsequently, male brains were isolated and the expression of genes encoding estrogenic receptors ERα, ERβ1 and ERβ2, the androgen receptor AR, and the aromatase cyp19a1b were compared with the expression in brains of unexposed males. (In this article gene expression is taken synonymous to transcription, although it is acknowledged that it can also be regulated by, e.g., mRNA and protein stability, and translation). The results confirmed that the male reproductive behavior was unaffected by the EE2 treatments. Also, the expressions of genes encoding estrogen and androgen receptors were unaffected. Only the gene encoding aromatase was 0.6 fold down-regulated. In contrast, and most surprisingly, nearly all the elements in the female courtship behavior were significantly disturbed, despite the fact that these females had never been exposed to EE2; most likely elicited by differences in male morphology, pheromones or some other unrevealed mechanism.

    Esophageal cancer (EC) is one of the most aggressive malignancies of the upper aerodigestive tract. Over the past three decades, with advances in surgical techniques and treatment, the prognosis of esophageal cancer has only slowly improved. Thus identifying novel molecular targets and developing therapeutic agents are critical. Aurora kinases play a crucial role in mitosis and selective inhibitors might provide an effective therapeutic treatment for cancer. However, the role of Aurora kinases in EC is still inadequately studied. Here, we identified a novel compound, referred to as APIO-EE-9, which inhibits growth and colony formation and induces apoptosis of esophageal cancer cells. Using computer modeling, we found that APIO-EE-9 interacted with both Aurora A and B in the ATP-binding pocket. APIO-EE-9 inhibited both Aurora A and B kinase activities in a dose-dependent manner. Treatment with APIO-EE-9 substantially reduced the downstream Aurora kinase phosphorylation of histone H3 (Ser10), resulting in formation of multiple nuclei and centrosomes. Additionally, esophageal cancer cells expressing shAurora A or shAurora B kinase exhibited a dramatic reduction in proliferation and colony formation. Injection of these cells as xenografts in mice reduced tumor formation compared to wildtype cells. Importantly, APIO-EE-9 significantly decreased the size of esophageal patient-derived xenograft (PDX) tumors implanted in SCID mice. These results demonstrated that APIO-EE-9 is a specific Aurora kinase inhibitor that could be developed as a therapeutic agent against esophageal cancer.

    The International Conference on Acoustic and Radio EeV Neutrino Activities, ARENA 2006 was jointly hosted by the Universities of Northumbria and Sheffield at the City of Newcastle Campus of the University of Northumbria in June 2006. ARENA 2006 was the latest in a series of meetings which have addressed, either separately or jointly, the use of radio and acoustic sensors for the detection of highly relativistic particles. Previous successful meetings have taken place in Los Angeles (RADHEP, 2000), Stanford (2003) and DESY Zeuthen (ARENA 2005). A total of 50 scientists from across Europe, the US and Japan attended the conference presenting status reports and results from a number of projects and initiatives spread as far afield as the Sweden and the South Pole. The talks presented at the meeting and the proceedings contained herein represent a `snapshot' of the status of the fields of acoustic and radio detection at the time of the conference. The three day meeting also included two invited talks by Dr Paula Chadwick and Dr Johannes Knapp who gave excellent summaries of the related astroparticle physics fields of high energy gamma ray detection and high energy cosmic ray detection respectively. As well as a full academic agenda there were social events including a Medieval themed conference banquet at Lumley Castle and a civic reception kindly provided by the Lord Mayor of Newcastle and hosted at the Mansion House. Thanks must go to the International Advisory Board members for their input and guidance, the Local Organising Committee for their hard work in bringing everything together and finally the delegates for the stimulating, enthusiastic and enjoyable spirit in which ARENA 2006 took place.

    This report summarizes a study and corresponding model development conducted in support of the United States Pacific Command (USPACOM) as part of the Federal Energy Management Program (FEMP) American Reinvestment and Recovery Act (ARRA). This research was aimed at developing a mathematical programming framework and accompanying optimization methodology in order to simultaneously evaluate energy efficiency (EE) and renewable energy (RE) opportunities. Once developed, this research then demonstrated this methodology at a USPACOM installation - Camp H.M. Smith, Hawaii. We believe this is the first time such an integrated, joint EE and RE optimization methodology has been constructed and demonstrated.

    In this paper, we investigate the production of a pair of doubly charged leptons associated with a gauge boson V(γ or Z) at future linear colliders via e+e- and γγ collisions. The numerical results show that the possible signals of the doubly charged leptons may be detected via the processes e+e- → VX++X-- and γγ → VX++X-- at future ILC or CLIC experiments.

    Cross sections, angular distributions and forward-backward asymmetries are presented, of two-fermion events produced in e+e- collisions at centre-of-mass energies from 189 to 209 GeV at LEP, measured with the ALEPH detector. Results for e+e-, μ+μ-, τ+τ-, qq¯, bb¯ and cc¯ production are in agreement with the standard model predictions. Constraints are set on scenarios of new physics such as four-fermion contact interactions, leptoquarks, Z‧ bosons, TeV-scale quantum gravity and R-parity violating squarks and sneutrinos.

  15. Atmospheric reactions between E,E-2,4-hexadienal and OH, NO3 radicals and Cl atoms

    E,E-2,4-Hexadienal is an α,β-unsaturated aldehyde whose presence in the atmosphere can arise from different sources. The rate coefficients for the reaction of this compound with Cl atoms, OH and NO3 radicals and for the photolysis process have been determined at atmospheric pressure and room temperature. A relative method has been developed with a Fourier Transform Infrared spectrometer (FTIR) or Solid Phase Micro Extraction fiber/chromatography-mass spectrometer (SPME/GC-MS) used as sampling/detection techniques. The absolute rate coefficients k (in units of cm3 molecule-1 s-1) obtained for Cl, OH and NO3 were (3.98 ± 0.44) × 10-10, (6.78 ± 0.47) × 10-11 and (1.34 ± 0.56) × 10-12, respectively. An estimation of the rate coefficient for the reaction of E,E-2,4-hexadienal with OH and NO3 radicals and Cl atoms has been carried out using correlations and SAR methods. The SAR substituent factor for the -C(O)H group, [G-(C(O)H)] = 3.58 × 10-3, has been obtained. This group reactivity factor allows the rate coefficients to be estimated for the reaction of unsaturated aldehydes with NO3 radicals. The results of this study confirm that the reaction of unsaturated aldehydes with Cl atoms is very fast and that the structure of the compound has little influence, with the influence of the structure being more marked in the case of the OH radical reaction and relatively large for the NO3 reaction. The results are consistent with a mechanism in which the first stage is addition of an atom or radical to the double bond of E,E-2,4-hexadienal as the main reaction channel and, to a minor extent, the abstraction of aldehydic hydrogen. These are the first data reported for the atmospheric reactions of this compound and this study therefore contributes to the database of rate coefficients for atmospheric reactions.

  16. Measurement of the Inclusive $Z \\to ee$ Production Cross Section in Proton-Proton Collisions at $\\sqrt{s}$ = 7TeV and $Z \\to ee$ Decays as Standard Candles for Luminosity at the Large Hadron Collider

    This thesis comprises a precision measurement of the inclusive \\Zee production cross section in proton-proton collisions provided by the Large Hadron Collider (LHC) at a center-of-mass energy of $\\sqrt{s}=7$~TeV and the absolute luminosity based on \\Zee decays. The data was collected by the Compact Muon Solenoid (CMS) detector near Geneva, Switzerland during the year of 2010 and corresponds to an integrated luminosity of $\\int\\mathcal{L}dt = 35.9\\pm 1.4$~pb$^{-1}$. Electronic decays of $Z$ bosons allow one of the first electroweak measurements at the LHC, making the cross section measurement a benchmark of physics performance after the first year of CMS detector and LHC machine operations. It is the first systematic uncertainty limited \\Zee cross section measurement performed at $\\sqrt{s}=7$~TeV. The measured cross section pertaining to the invariant mass window $M_{ee}\\in (60,120)$~GeV is reported as: $\\sigma(pp\\to Z+X) \\times \\mathcal{B}( Z\\to ee ) = 997 \\pm 11 \\mathrm{(sta t)} \\pm 19 \\mathrm{(syst)} \\pm 40 \\mathrm{(lumi)} \\textrm{ pb}$, which agrees with the theoretical prediction calculated to NNLO in QCD. Leveraging \\Zee decays as ``standard candles'' for measuring the absolute luminosity at the LHC is examined; they are produced copiously, are well understood, and have clean detector signatures. Thus the consistency of the inclusive \\Zee production cross section measurement with the theoretical prediction motivates inverting the measurement to instead use the \\Zee signal yield to measure the luminosity. The result, which agrees with the primary relative CMS luminosity measurement calibrated using Van der Meer separation scans, is not only the most precise absolute luminosity measurement performed to date at a hadron collider, but also the first one based on a physics signal at the LHC.

    In view of the significantly different proton charge radius extracted from muonic hydrogen Lamb shift measurements as compared to electronic hydrogen spectroscopy or electron-scattering experiments, we study in this Letter the photoproduction of a lepton pair on a proton target in the limit of very small momentum transfer as a way to provide a test of the lepton universality when extracting the proton charge form factor. By detecting the recoiling proton in the γ p →l-l+p reaction, we show that a measurement of a ratio of e-e++μ-μ+ over e-e+ cross sections with an absolute precision of 7 ×1 0-4 would allow for a test to distinguish, at the 3 σ level, between the two different proton charge radii currently extracted from muonic and electronic observables.

    In this paper, the color-octet long distance matrix elements are studied through the inclusive J/ψ production in e+e- annihilation within the framework of non-relativistic QCD factorization. The calculations are up-to next-to-leading order with the radiative and relativistic corrections in the energy region of the B-factory and the near-threshold region of 4.6{-}5.6 GeV. A constraint of the long distance matrix elements (< ^1S_08> , < ^3P_08> ) is obtained. Through our estimation, the P-wave color-octet matrix element (< 0|^3P^8_0|0> ) should be of the order of 0.008m_c^2 GeV^3 or less. The constrained region is not compatible with the values of the long distance matrix elements fitted at hadron colliders.

    We present measurements of Collins asymmetries in the inclusive process e+e- →h1h2X , h1h2=K K , K π , π π , at the center-of-mass energy of 10.6 GeV, using a data sample of 468 fb-1 collected by the BABAR experiment at the PEP-II B factory at SLAC National Accelerator Center. Considering hadrons in opposite thrust hemispheres of hadronic events, we observe clear azimuthal asymmetries in the ratio of unlike sign to like sign, and unlike sign to all charged h1h2 pairs, which increase with hadron energies. The K π asymmetries are similar to those measured for the π π pairs, whereas those measured for high-energy K K pairs are, in general, larger.

  20. γ-Ray polarimetry with conversions to e+e- pairs: Polarization asymmetry and the way to measure it

    We revisit the measurement of the polarization fraction, P, and of the polarization angle of partially linearly-polarized gamma rays using their conversion to e+e- pairs in the field of a nucleus. We show that an inappropriate definition of the azimuthal angle, φ, used to reference the orientation of the final state degrades the precision of the measurement of P, by comparison to the optimal case where the bisector angle of the electron and of the positron momenta is used. We then focus on the lowest part of the energy spectrum, below ≈ 10 MeV, where a large part of the statistics lie for a cosmic source. We obtain the value of the polarization asymmetry, A, of pair conversion at threshold and we show that in the case where the correct expression is used for φ, the measured value of A tends to the limit.
