description: We present a theoretical profile of the Lyman Beta line of atomic hydrogen perturbed by collisions with neutral hydrogen atoms and protons. We use a general unified theory in which the electric dipole moment varies during a collision. A collision-induced satellite appears on Lyman Beta, correlated to the B''\barB 1Sigma+u - X 1Sigma+g asymptotically forbidden transition of H_2. As a consequence, the appearance of the line wing between Lyman Alpha and Lyman Beta is shown to be sensitive to the relative abundance of hydrogen ions and neutral atoms, and thereby to provide a temperature diagnostic for stellar atmospheres and laboratory plasmas.

description: We investigate the effects of the intense terahertz laser field and the spin-orbit coupling on single electron spin in a quantum dot. The laser field and the spin-orbit coupling can strongly affect the electron density of states and can excite a magnetic moment. The direction of the magnetic moment depends on the symmetries of the system, and its amplitude can be tuned by the strength and frequency of the laser field as well as the spin-orbit coupling.

description: One-dimensional topological superconductors host Majorana zero modes (MZMs), the non-local property of which could be exploited for quantum computing applications. Spin- polarized scanning tunneling microscopy measurements show that MZMs realized in self- assembled Fe chains on the surface of Pb have a spin polarization that exceeds that due to the magnetism of these chains. This feature, captured by our model calculations, is a direct consequence of the nonlocality of the Hilbert space of MZMs emerging from a topological band structure. Our study establishes spin polarization measurements as a diagnostic tool to uniquely distinguish topological MZMs from trivial in-gap states of a superconductor.

description: Membrane paradigm is a powerful tool to study properties of black hole horizons. We first explore the properties of the nonlinear electromagnetic membrane of black holes. For a general nonlinear electrodynamics field, we show that the conductivities of the horizon usually have off-diagonal components and depend on the normal electric and magnetic fields on the horizon. Via the holographic duality, we find a model-independent expression for the holographic DC conductivities of the conserved current dual to a probe nonlinear electrodynamics field in a neutral and static black brane background. It shows that these DC conductivities only depend on the geometric and electromagnetic quantities evaluated at the horizon. We can also express the DC conductivities in terms of the temperature, charge density and magnetic field in the boundary theory, as well as the values of the couplings in the nonlinear electrodynamics at the horizon.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.

description: Three major outbreaks of Neospora abortion in 3 dairy herds in The Netherlands during 1992-1993 are reported. All outbreaks lasted 3 weeks, during the summer or early autumn, and were followed by the birth of mummified fetuses during the next 3 months. Unexpected heat in herdmates, previously diagnosed as pregnant, was also seen. There were 85 abortions in total. The length of gestation for 50 Neospora fetuses was 180ñ36 days. Within 1 year after the outbreak, 50% of the animals were culled. 49 cows were rebred. Fertility immediately after abortion was not impaired. 75 pregnancies were followed, including 21 during the second and 8 during the third year after the outbreak. 70 apparently healthy calves, including 5 sets of twins, were born. Three calves were stillborn. Three cows aborted a Neospora-infected fetus for the second time. Serial blood samples from 43 cows tested by an ELISA indicated a decrease in antibodies to Neospora to low or undetectable levels within 2 months after abortion. A rise of antibodies during the second half of gestation (following the initial outbreak) was recorded in 58% of the animals. Precolostral serum antibodies to Neospora, indicating intrauterine infection, were present in 68% of the calves tested. Seronegative cows produced seronegative calves. In all herds, seroprevalence increased after the outbreak.

description: Recent ab initio calculations [Mattausch et al., Phys. Rev. B 70, 235211 (2004)] of carbon clusters in SiC reveal a possible connection between the tricarbon antisite (C_3)_Si and the U photoluminescence center in 6H-SiC [Evans et al., Phys. Rev. B 66, 35204 (2002)]. Yet, some of the predicted vibrational modes were not observed experimentally. Here we report experiments which indeed confirm the existence of a low-energy mode for the U-center (as well as for the HT3- and HT4-centers with spectral details similar to the U-center). We calculated the isotope splitting for the (C_3)_Si-defect and found near-perfect agreement with our data. In addition, we discuss the carbon di-interstitial (C_2)_Hex as a model for the Z- and HT5-centers. The isotope splitting is also well reproduced, but the absolute values of the local mode energies show a discrepancy of about 10 meV.

description: We present an analysis of 55 central galaxies in clusters and groups with molecular gas masses and star formation rates lying between $10^{8}-10^{11}\ M_{\odot}$ and $0.5-270$ $M_{\odot}\ yr^{-1}$, respectively. We have used Chandra observations to derive profiles of total mass and various thermodynamic variables. Molecular gas is detected only when the central cooling time or entropy index of the hot atmosphere falls below $\sim$1 Gyr or $\sim$35 keV cm$^2$, respectively, at a (resolved) radius of 10 kpc. This indicates that the molecular gas condensed from hot atmospheres surrounding the central galaxies. The depletion timescale of molecular gas due to star formation approaches 1 Gyr in most systems. Yet ALMA images of roughly a half dozen systems drawn from this sample suggest the molecular gas formed recently. We explore the origins of thermally unstable cooling by evaluating whether molecular gas becomes prevalent when the minimum of the cooling to free-fall time ratio ($t_{\rm cool}/t_{\rm ff}$) falls below $\sim10$. We find: 1) molecular gas-rich systems instead lie between $10 < min(t_{\rm cool}/t_{\rm ff}) < 25$, where $t_{\rm cool}/t_{\rm ff}=25$ corresponds approximately to cooling time and entropy thresholds $t_{\rm cool} \lesssim 1$ Gyr and 35 keV~cm$^2$, respectively, 2) $min(t_{\rm cool}/t_{\rm ff}$) is uncorrelated with molecular gas mass and jet power, and 3) the narrow range $10 < min(t_{\rm cool}/t_{\rm ff}) < 25$ can be explained by an observational selection effect. These results and the absence of isentropic cores in cluster atmospheres are in tension with "precipitation" models, particularly those that assume thermal instability ensues from linear density perturbations in hot atmospheres. Some and possibly all of the molecular gas may instead have condensed from atmospheric gas lifted outward either by buoyantly-rising X-ray bubbles or merger-induced gas motions.

description: The one-loop vacuum energy is explicitly computed for a class of perturbative string vacua where supersymmetry is spontaneously broken by a T-duality invariant asymmetric Scherk-Schwarz deformation. The low-lying spectrum is tachyon-free for any value of the compactification radii and thus no Hagedorn-like phase-transition takes place. Indeed, the induced effective potential is free of divergence, and has a global anti de Sitter minimum where geometric moduli are naturally stabilised.

description: We design and demonstrate on-chip homodyne detection operating in the quantum regime, i.e. able to detect genuine nonclassical features. Our setup exploits a glass-integrated homodyne analyzer (IHA) entirely fabricated by femtosecond laser micromachining. The IHA incorporates on the same chip a balanced waveguide beam splitter and a thermo-optic phase shifter, allowing us to record homodyne traces at different phases and to perform reliable quantum state tomography. In particular, we show that the IHA allows for the detection of nonclassical features of continuous-variable quantum states, such as squeezed states.

description: During low-light conditions, drivers rely mainly on headlights to improve visibility. But in the presence ofrain and snow, headlights can paradoxically reduce visibility due to light reflected off of precipitation back towards the driver. Precipitation also scatters light across a wide range of angles that disrupts the vision of drivers in oncoming vehicles. In contrast to recent computer vision methods that digitally remove rain and snow streaks from captured images, we present a system that will directly improve driver visibility by controlling illumination in response to detected precipitation. The motion of precipitation is tracked and only the space around particles is illuminated using fast dynamic control. Using a physics-based simulator, we show how such a system would perform under a variety of weather conditions. We build and evaluate a proof-of-concept system that can avoid water drops generated in the laboratory.

description: Firearms and penetrating captive-bolt devices are commonly used to euthanize cattle of all ages, and result in rapid unconsciousness and death due to lethal brain damage when properly conducted. Several reports have described methods to determine the appropriate point of entry when using firearms or penetrating captive bolts for bovine euthanasia. However, some previously described techniques to determine the point of entry may be difficult to remember, necessitate multiple steps to ascertain the point of entry, require adjustment based on breed type, and/or may be challenging in polled cattle if the suggested protocol uses horn anatomy as part of the guidance. A simple, reliable description for an appropriate point of entry and trajectory course for a firearm or captive bolt is to direct the trajectory perpendicular or slightly downward to the frontal sinus plane on midline between the base of the ears at the level of the external acoustic meatus. The orientation of the brainstem and ear is not altered by variables considered in some other protocols. The objective of this report is to describe and justify an uncomplicated, repeatable protocol to consistently determine an appropriate point of entry and line of trajectory for firearm or penetrating captive-bolt euthanasia of domestic bovines across a variety of breeds, ages, skull types, and polled or horned cattle, thus increasing the likelihood that the procedure will be conducted quickly and humanely with minimal stress to the handler and the animal.

description: It is shown that background fields of a topological character usually introduced as such in compactified string theories correspond to quantum degrees of freedom which parametrise the freedom in choosing a representation of the zero mode quantum algebra in the presence of non-trivial topology. One consequence would appear to be that the values of such quantum degrees of freedom, in other words of the associated topological background fields, cannot be determined by the nonperturbative string dynamics.

description: This study examined the effect of compost fortified with rock dust on the soil properties, soil microbial activity, and yield and fruit quality in a mature apple orchard from the Jiangsu province of China. The incorporation of rock dust significantly improved the microelement contents of Ca, Mg, Fe, Mn, Zn, B, and Al, but without increasing phytotoxicity of the compost. The fortified compost had higher metabolic activity and functional diversity of microorganisms as determined by the community-level physiological profiling with Biolog EcoPlates. The two-year incorporation of the rock dust compost into a poor-quality soil led to a significant increase in the yield with the increase of 120% and 187% compared to untreated control in 2013 and 2014, respectively. Application of the rock dust compost obviously promoted superoxide dismutase (SOD) activity and concentration of vitamin C in mature apple trees. The beneficial effects coincided with higher microbial activity and shifts in the composition of the soil microbiome. Our results demonstrate that the practice of combining the rock dust-fortified compost with NPK fertilizers provides a cost-effective way of supplying crops with macro-and micronutrients ensuring better vegetative growth and higher yields.

description: Measurements of root-zone soil moisture across spatial scales of tens to thousands of meters have been a challenge for many decades. The mobile application of Cosmic-Ray Neutron Sensing (CRNS) is a promising approach to measure field soil moisture non-invasively by surveying large regions with a ground-based vehicle. Recently, concerns have been raised about a potentially biasing influence of local structures and roads. We employed neutron transport simulations and dedicated experiments to quantify the influence of different road types on the CRNS measurement. We found that the presence of roads introduces a bias in the CRNS estimation of field soil moisture compared to non-road scenarios. However, this effect becomes insignificant at distances beyond a few meters from the road. Measurements from the road could overestimate the field value by up to 40 % depending on road material, width, and the surrounding field water content. The bias could be successfully removed with an analytical correction function that accounts for these parameters. Additionally, an empirical approach is proposed that can be used on-the-fly without prior knowledge of field soil moisture. Tests at different study sites demonstrated good agreement between road-effect corrected measurements and field soil moisture observations. However, if knowledge about the road characteristics is missing, any measurements on the road could substantially reduce the accuracy of this method. Our results constitute a practical advancement of the mobile CRNS methodology, which is important for providing unbiased estimates of field-scale soil moisture to support applications in hydrology, remote sensing, and agriculture.

description: We study distributed optimization problems when N nodes minimize the sum of their individual costs subject to a common vector variable. The costs are convex, have Lipschitz continuous gradient (with constant L), and bounded gradient. We propose two fast distributed gradient algorithms based on the centralized Nesterov gradient algorithm and establish their convergence rates in terms of the per-node communications K and the per-node gradient evaluations k. Our first method, Distributed NesterovGradient, achieves rates O( logK/K) and O(logk/k). Our second method, Distributed Nesterov gradientwith Consensus iterations, assumes at all nodes knowledge of L and μ(W) - the second largest singular value of the N ×N doubly stochastic weight matrix W. It achieves rates O( 1/ K2-ξ) and O( 1/k2) ( ξ > 0 arbitrarily small). Further, we give for both methods explicit dependence of the convergence constants on N and W. Simulation examples illustrate our findings.

description: In this paper we present the analysis of two broad band (0.1-150 keV) BeppoSAX observations of the Seyfert 1 galaxy NGC 3516. The two observations were taken 4 months apart, on 1996 November 8 and 1997 March 12 respectively. We report a dramatic change in the degree of obscuration of the central source between the two observations, and propose, as possible explanations transient absorption by either a stationary-state cloud of cold gas crossing the line of sight, or a varying-state, initially neutral and dense amount of expanding gas with decreasing density and therefore decreasing opacity. We also report the detection of a second highly ionized absorber/emitter, which causes deep FeXVII-XXII K edges at about 7.8 keV to appear in both BeppoSAX spectra of NGC 3516, and possibly produces the soft X-ray continuum emission and the 1 keV blend of Fe L recombination lines detected during the epoch of heavy nuclear obscuration.

description: This study evaluated the behavior of calves following different disbudding methods, and evaluated the scarring between these methods in the weeks that followed. Dairy calves (1 to 15 days of age) were subjected to 1 of 3 methods: caustic paste (CP n = 123), caustic stick (CS n = 123), and hot-iron+lidocaine (HI n = 130). The calf’s latency to approach a person was recorded 1 day and 7 days after disbudding. Calves in the caustic paste group were more likely to approach after 1 sec compared to the other methods. Hot- iron+lidocaine disbudding produced smaller scars (0.47 ± 0.26 in (1.2 ± 0.67 cm) mean diameter ± SD vs CS = 1.5 ± 0.47 in (3.8 ± 1.2 cm) and CP = 1.2 ± 0.35 in (3.1 ± 0.90 cm)), but had greater odds of redness (OR = 6.6), purulent discharge (OR = 13.6), and crust (OR = 48.9) 3 weeks after disbudding compared to the caustic methods. Weight gain at 6 weeks was similar between treatment groups. Horn regrowth at 6 weeks and 6 months after disbudding was not different between the methods used, and thus caustic chemicals were as effective as the hot-iron+lidocaine method to disbud dairy calves.

description: The purpose of this study was to estimate the cow- and herd-level prevalence of subclinical ketosis (SCK) on dairies in the state of Washington and evaluate the arithmetic mean of individual samples as a proxy for pooled-sample testing to screen herds for SCK. The cow-level prevalence of SCK in 589 cows from 40 Washington dairies was 31,25, and 19% using P-hydroxybutyrate (BHB) concentration cutpoints of > 1.0, 1.2, and 1.4 mmol/L, respectively. For all BHB cutpoints, no difference was observed in the prevalence of SCK between cows of parity 1 and 2 (P > 0.358), but SCK was higher in cows of parity > 3 versus those in lactations 1 and 2 (P <0.001). The mean BHB concentration (mmol/L) in cows of parity > 3 (1.16) was higher than that of parity 1 (0.72) and parity 2 (0.88) cows (P <0.001). Using a BHB cutpoint of > 1.2 mmol/L and herd alarm level of >15% cows exceeding that cutpoint, 23 herds (58%) demonstrated a herd-level problem with SCK. When a BHB cutpoint of > 1.4 and herd alarm level of >25% was used, 12 herds (30%) had SCK. A herd mean BHB concentration of 0.77 mmol/L was correlated with a 15% herd-alarm level using a > 1.2 mmol/L BHB cutpoint. Sensitivity and specificity of the herd mean BHB cutpoint of >0.8 mmol/L to identify herds with > 15% cows with BHB > 1.2 mmol/L was 91 and 75%, respectively. The prevalence of SCK in Washington dairies was numerically higher than previous reports. Results of this study highlight the importance of obtaining representative samples from parity risk groups. Furthermore, results suggest parity 2 cows may be better grouped with parity 1 rather than > 3 parity cows. Herd mean BHB concentration performed well as a test to identify herds with a potential SCK problem when a mean value specific cutpoint was used. Further research evaluating the relationship between pooled-sample BHB and important outcomes, such as disease, milk production, reproduction, and removal, are needed.

description: Bitwise operations are an important component of modern day programming, and are used in a variety of applications such as databases. In this work, we propose a new and simple mechanism to implement bulk bitwise AND and OR operations in DRAM, which is faster and more efficient than existing mechanisms. Our mechanism exploits existing DRAM operation to perform a bitwise AND/OR of two DRAM rows completely within DRAM. The key idea is to simultaneously connect three cells to a bitline before the sense-amplification. By controlling the value of one of the cells, the sense amplifier forces the bitline to the bitwise AND or bitwise OR of the values of the other two cells. Our approach can improve the throughput of bulk bitwise AND/OR operations by 9:7X and reduce their energy consumption by 50:5X. Since our approach exploits existing DRAM operation as much as possible, it requires negligible changes to DRAM logic. We evaluate our approach using a real-world implementation of a bit-vector based index for databases. Our mechanism improves the performance of commonly-used range queries by 30% on average.

description: The origin and survival of the Smith high-velocity HI cloud has so far defied explanation. This object has several remarkable properties: (i) its prograde orbit is ~100 km/s faster than the underlying Galactic rotation; (ii) its total gas mass ($\gtrsim 4 \times 10^6 ~{\rm M}_{\odot}$) exceeds the mass of all other high-velocity clouds (HVC) outside of the Magellanic Stream; (iii) its head-tail morphology extends to the Galactic HI disc, indicating some sort of interaction. The Smith Cloud's kinetic energy rules out models based on ejection from the disc. We construct a dynamically self-consistent, multi-phase model of the Galaxy with a view to exploring whether the Smith Cloud can be understood in terms of an infalling, compact HVC that has transited the Galactic disc. We show that while a dark-matter (DM) free HVC of sufficient mass and density can reach the disc, it does not survive the transit. The most important ingredient to survival during a transit is a confining DM subhalo around the cloud; radiative gas cooling and high spatial resolution ($\lesssim$ 10 pc) are also essential. In our model, the cloud develops a head-tail morphology within ~10 Myr before and after its first disc crossing; after the event, the tail is left behind and accretes onto the disc within ~400 Myr. In our interpretation, the Smith Cloud corresponds to a gas 'streamer' that detaches, falls back and fades after the DM subhalo, distorted by the disc passage, has moved on. We conclude that subhalos with ${\rm M}_{\rm DM} \lesssim 10^9 ~{\rm M}_{\odot}$ have accreted $\sim10^9 ~{\rm M}_{\odot}$ of gas into the Galaxy over cosmic time - a small fraction of the total baryon budget.

description: We have studied the magnetic and thermodynamic properties as well as the NMR spectra of the Heisenberg antiferromagnet RbFe(MoO4)2. The observed temperature dependence of the order parameter, the critical indices and the overall magnetic H-T phase diagram are all in a good agreement with the theoretical predictions for a 2D XY model. The temperature dependence of the specific heat at low temperature demonstrates a crossover from a T^2 law characteristic of a two-dimensional antiferromagnet to a three-dimensional T^3 law.

description: Dose-Response Functions (DRFs) are widely used in estimating corrosion and/or soiling levels of materials used in constructions and cultural monuments. These functions quantify the effects of air pollution and environmental parameters on different materials through ground based measurements of specific air pollutants and climatic parameters. Here, we propose a new approach where available satellite observations are used instead of ground-based data. Through this approach, the usage of DRFs is expanded in cases/areas where there is no availability of in situ measurements, introducing also a totally new field where satellite data can be shown to be very helpful. In the present work satellite observations made by MODIS (MODerate resolution Imaging Spectroradiometer) on board Terra and Aqua, OMI (Ozone Monitoring Instrument) on board Aura and AIRS (Atmospheric Infrared Sounder) on board Aqua have been used.

description: Direct implementations of bilateral filtering show O(r2) computational complexity per pixel, where r is the filter window radius. Several lower complexity methods have been developed. State-of-the-art low complexity algorithm is an O(1) bilateral filtering, in which computational cost per pixel is nearly constant for large image size. Although the overall computational complexity does not go up with the window radius, it is linearly proportional to the number of quantization levels of bilateral filtering computed per pixel in the algorithm. In this paper, we show that overall runtime depends on two factors, computing time per pixel per level and average number of levels per pixel. We explain a fundamental trade-off between these two factors, which can be controlled by adjusting block size. We establish a model to estimate run time and search for the optimal block size. Using this model, we demonstrate an average speedup of 1.2-26.0x over the previous method for typical bilateral filtering parameters.

description: Crossbred steers (n=l,370) purchased from auction markets in Texas were received into a commercial feedlot near Hereford, Texas. Steers were recently weaned and considered at high risk of developing bovine respiratory disease (BRO). Upon arrival, steers were randomly assigned (within arrival blocks) to 1 of 3 treatment groups that received: 1) tilmicosin (TLM; 4.5 mg/lb (10.0 mg/kg)), 2) tildipirosin (TLD; 1.82 mg/lb ( 4.0 mg/kg)), or 3) tulathromycin (TUL; 1.14 mg/lb (2.5 mg/kg)). Steers were penned by treatment into 36 pens with 12 pens per treatment. Data were analyzed with linear mixed models for a randomized complete block design. Steers administered TUL had significantly lower BRO morbidity than both TLD and TLM (P< 0.01) treatments, and TLD had lower BRO morbidity than TLM (P < 0.05). Cattle receiving TUL also had a lower percentage of chronic illness than both TLD and TLM treatments (P < 0.05). Steers in the TUL treatment group had lower BRO and overall mortality at closeout than TLD (P < 0.05), but the TLM-treated steers did not differ from the other groups. Deads-in average daily gain was 0.55 lb (0.25 kg) greater in TUL-treated steers than steers administered TLM, and 0.56 lb (0.25 kg) greater than steers receiving TLD (P < 0.05). Cattle receiving TUL had 1.33 lb (0.6 kg) lower deads-in feed-to-gain ratio at closeout than those receiving TLM, and 1.51 lb (0.68 kg) lower than those receiving TLD (P < 0.05). During the first 30 days-onfeed, TUL-treated steers had greater daily dry-matter intake compared with TLD-treated steers (P < 0.01), but no other differences among treatment groups. By closeout, there were no differences in cumulative mean dry-matter intake between treatment groups. Overall, TUL treatment on arrival resulted in improved health and performance as compared to TLM and TLD treatments.

An Improved Iterative HDG Approach for Partial Differential Equations

description: We propose and analyze an iterative high-order hybridized discontinuous Galerkin (iHDG) discretization for linear partial differential equations. We improve our previous work (SIAM J. Sci. Comput. Vol. 39, No. 5, pp. S782--S808) in several directions: 1) the improved iHDG approach converges in a finite number of iterations for the scalar transport equation; 2) it is unconditionally convergent for both the linearized shallow water system and the convection-diffusion equation; 3) it has improved stability and convergence rates; 4) we uncover a relationship between the number of iterations and time stepsize, solution order, meshsize and the equation parameters. This allows us to choose the time stepsize such that the number of iterations is approximately independent of the solution order and the meshsize; and 5) we provide both strong and weak scalings of the improved iHDG approach up to $16,384$ cores. A connection between iHDG and time integration methods such as parareal and implicit/explicit methods are discussed. Extensive numerical results are presented to verify the theoretical findings.
