description: We use the synergy of infrared, terahertz, and Raman spectroscopies with DFT calculations to shed light on the magnetic and lattice properties of VI3. The structural transition at TS1 = 79 K is accompanied by a large splitting of polar phonon modes. Below TS1, strong ferromagnetic fluctuations are observed. The variations of phonon frequencies at 55 K induced by magnetoelastic coupling enhanced by spin-orbit interaction indicate the proximity of long-range ferromagnetic order. Below TC = 50 K, two Raman modes simultaneously appear and show dramatic softening in the narrow interval around the temperature TS2 of the second structural transition associated with the order-order magnetic phase transition. Below TS2, a magnon in the THz range appears in Raman spectra. The THz magnon observed in VI3 indicates the application potential of 2D van der Waals ferromagnets in ultrafast THz spintronics, which has previously been considered an exclusive domain of antiferromagnets.

description: The question everyone always wants to know is how to get paid for what you do. As I have traveled around from practice to practice, I have seen a great deal of different ways to charge for your services. It is hard to say which is right and which is wrong but it is important to choose a method that best fits your style of practice. The important question that must be asked by every veterinarian is how much of my time am I really getting paid for? When one actually takes the time to figure out his real chargeable hours per day, the results can be disappointing. Most veterinarians make around $50 per hour for their program work. If the average veterinarian spends 60 hours of week working and works 50 weeks a year, the average income for their service time only should be $150,000 per year plus drugs and supplies. Unfortunately, many veterinarians income for services fall far short of this. Take the time a figure your real hourly rate rather than the rate you actually charge. Are you disappointed?

description: These lecture notes accompany two classes given at the NRHEP2 school. In the first lecture I introduce the basic concepts used for analyzing well-posedness, that is the existence of a unique solution depending continuously on given data, of evolution partial differential equations. I show how strong hyperbolicity guarantees well-posedness of the initial value problem. Symmetric hyperbolic systems are shown to render the initial boundary value problem well-posed with maximally dissipative boundary conditions. I discuss the Laplace-Fourier method for analyzing the initial boundary value problem. Finally I state how these notions extend to systems that are first order in time and second order in space. In the second lecture I discuss the effect that the gauge freedom of electromagnetism has on the PDE status of the initial value problem. I focus on gauge choices, strong-hyperbolicity and the construction of constraint preserving boundary conditions. I show that strongly hyperbolic pure gauges can be used to build strongly hyperbolic formulations. I examine which of these formulations is additionally symmetric hyperbolic and finally demonstrate that the system can be made boundary stable.

description: One of my biggest frustrations in providing dairy nutrition services has been the unwillingness of some clients to spend the "front money" to get a good program underway. Some nutrition problems (e.g. protein shortage) can be solved in rapid fashion. Others, such as underconditioned cows producing and reproducing poorly, will take six to ten months for real results to show in the bulk tank.

description: The generation of accurate tip angles is critical for many applications of nuclear magnetic resonance. In low static field, with a linear rather than circular polarized rf field, the rotating-wave approximation may no longer hold and significant deviations from expected trajectories on the Bloch sphere can occur. For rectangular rf pulses, the effects depend strongly on the phase of the rf field and can be further compounded by transients at the start and end of the pulse. The desired terminus can be still be achieved, however, through the application of a phase-dependent Bloch-Siegert shift and appropriate consideration of pulse timings. For suitably shaped rf pulses, the Bloch-Siegert shift is largely phase independent, but its magnitude can vary significantly depending on details of the pulse shape as well as the characteristics of the rf coil circuit. We present numerical simulations and low-field NMR experiments with 1H and 3He that demonstrate several main consequences and accompanying strategies that one should consider when wanting to generate accurate tip angles outside the validity of the rotating-wave approximation and in low static field.

The old style "brown arm" herd health programs are rapidly evolving into production medicine programs that stress many additional areas of dairy and beef management. Of all the ingredients of successful production medicine programs the two most important are enthusiasm and profit.

description: We discuss the impact of residual nuclear burning in the cooling sequences of hydrogen-rich DA white dwarfs with very low metallicity progenitors ($Z=0.0001$). These cooling sequences are appropriate for the study of very old stellar populations. The results presented here are the product of self-consistent, fully evolutionary calculations. Specifically, we follow the evolution of white dwarf progenitors from the zero-age main sequence through all the evolutionary phases, namely the core hydrogen-burning phase, the helium-burning phase, and the thermally pulsing asymptotic giant branch phase to the white dwarf stage. This is done for the most relevant range of main sequence masses, covering the most usual interval of white dwarf masses --- from $0.53\, M_{\sun}$ to $0.83\, M_{\sun}$. Due to the low metallicity of the progenitor stars, white dwarfs are born with thicker hydrogen envelopes, leading to more intense hydrogen burning shells as compared with their solar metallicity counterparts. We study the phase in which nuclear reactions are still important and find that nuclear energy sources play a key role during long periods of time, considerably increasing the cooling times from those predicted by standard white dwarf models. In particular, we find that for this metallicity and for white dwarf masses smaller than about $0.6\, M_{\sun}$, nuclear reactions are the main contributor to the stellar luminosity for luminosities as low as $\log(L/L_{\sun})\simeq -3.2$. This, in turn, should have a noticeable impact in the white dwarf luminosity function of low-metallicity stellar populations.

description: In Canada, we have two levels of government: the federal Government of Canada and the provincial governments. To accompany this fancy political governing system, we also have two internal revenue systems, one federal and one provincial. If you are working for dollars, you definitely have to collect for it. I come from the Province of Quebec. from the iegion we refer to as the Richelieu Valley situated in the most southern area of the province which coincides with the most northern area of the Vermont State,. It is situated south-east of Montreal, limited to the west by the Richelieu River which runs from the Champlain lake to the St. Lawrence river. In this area, most of the producers are referred to as industrial type dairy producers. The typical farm is a family farm which owns approximately 150 head of cattle. The largest farm milks 350 cows and owns approximately 800 head. In this province, nothing seems to be done like anywhere else in this country. Politicians, in the past, managed to have the western producers produce grains that were shipped to the east to produce milk. Approximately 55% of the milk produced in Canada is produced in Quebec. We do not speak the same language, and we always seem to do things in a complicated manner.

description: The veterinary profession, particularly veterinarians who earn their living from any species where economics rather than emotion dictates their income, are facing challenging times. We have an opportunity unlike any time in the recent past to change the way we do business and meet the needs of an increasingly sophisticated client and the complex health problems which occur on more and more intensive livestock operations. For the past ten to fifteen years, the veterinary profession has embraced and promoted the concept of "herd health," and told innumerable students to go out and sell the concept. I'm sure many people in this audience have felt the frustration associated with taking this idea and putting it into practice. If we truly believe this is the approach to take, then it is essential that the veterinary profession identify clients who will accept these principles and provide the enthusiasm and the technical expertise to make this occur. One of the most common problems encountered in selling herd health has been in being paid appropriately for services which are not all of the task-oriented type.

description: A theory for sequence dependent liquid-liquid phase separation (LLPS) of intrinsically disordered proteins (IDPs) in the study of biomolecular condensates is formulated by extending the random phase approximation (RPA) and field-theoretic simulation (FTS) of heteropolymers with spatially long-range Coulomb interactions to include the fundamental effects of short-range, hydrophobic-like interactions between amino acid residues. To this end, short-range effects are modeled by Yukawa interactions between multiple nonelectrostatic charges derived from an eigenvalue decomposition of pairwise residue-residue contact energies. Chain excluded volume is afforded by incompressibility constraints. A mean-field approximation leads to an effective Flory $χ$ parameter, which, in conjunction with RPA, accounts for the contact-interaction effects of amino acid composition and the sequence-pattern effects of long-range electrostatics in IDP LLPS, whereas FTS based on the formulation provides full sequence dependence for both short- and long-range interactions. This general approach is illustrated here by applications to variants of a natural IDP in the context of several different amino-acid interaction schemes as well as a set of different model hydrophobic-polar sequences sharing the same composition. Effectiveness of the methodology is verified by coarse-grained explicit-chain molecular dynamics simulations.

How about treating a client's best cow for acute watery mastitis? Or having to recommend euthanasia for a cow with a fractured pelvis? Although all of these are equally difficult, I believe one of the most arduous tasks we face as professionals is charging a fair fee for our services. Gone are the days of an annual billing. The one line ticket of "Visit Cow - $35.00" is also a thing of the past. To determine a professional fee that is fair and equitable to both parties, I have found being "Paid by the Procedure" most satisfactory.

description: Several recent works have considered the pressure exerted on a wall by a model polymer. We extend this consideration to vesicles attached to a wall, and hence include osmotic pressure. We do this by considering a two-dimensional directed model, namely that of area-weighted Dyck paths. Not surprisingly, the pressure exerted by the vesicle on the wall depends on the osmotic pressure inside, especially its sign. Here, we discuss the scaling of this pressure in the different regimes, paying particular attention to the crossover between positive and negative osmotic pressure. In our directed model, there exists an underlying Airy function scaling form, from which we extract the dependence of the bulk pressure on small osmotic pressures.

description: We investigate optical bistability in a multilayer one-dimensional photonic crystal where the central layer is doped with $Λ$-type three level atoms. We take into account the influence of spontaneously generated coherence when the lower atomic levels are sufficiently close to each other, in which case Kerr-type nonlinear response of the atoms is enhanced. We calculate the propagation of a probe beam in the defect mode window using numerical nonlinear transfer matrix method. We find that Rabi frequency of a control field acting on the defect layer and the detuning of the probe field from the atomic resonance can be used to control the size and contrast of the hysteresis loop and the threshold of the optical bistability. In particular we find that, at the optimal spontaneously generated coherence, three orders of magnitude lower threshold can be achieved relative to the case without the coherence.

Especially interesting is the continuous limit from $5d$ to $4d$ and its description at the level of equations for eight $τ$-functions. Half of these equations are governed by integrability and another half by Ward identities.

Publisher: name: American Association of Bovine Practitioners  Proceedings of the Annual Conference
Year: 1988

description: The respiratory system of mammals plays a critical role in external respiration; the exchange of gases between the ambient atmosphere and the blood. In addition to this function, the respiratory system is significantly involved in body temperature control, vocalization, immunity to inhaled antigens, antimicrobial action, detoxication, olfaction and a number of important metalbolic and endocrine functions. In considerations of the pathogenesis of respiratory disease and in the planning of therapeutic regimens, maintaining the primary function of gas exchange is of critical importance, but the effects on other respiratory functions must also be considered. In this review, therapeutic intervention in bovine respiratory disease will be reviewed with the goal of selecting therapetic agents that optimze respiratory and tissue defense mechanisms and minimizing damage produced by infectious agents or tissue reactions to these organisms.

description: This paper presents a multiscale analysis of a dilatant shear band using a three-dimensional discrete element method and a lattice Boltzmann/finite element hybrid scheme. In particular, three-dimensional simple shear tests are conducted via the discrete element method. A spatial homogenization is performed to recover the macroscopic stress from the micro-mechanical force chains. The pore geometries of the shear band and host matrix are quantitatively evaluated through morphology analyses and lattice Boltzmann/finite element flow simulations. Results from the discrete element simulations imply that grain sliding and rotation occur predominately with the shear band. These granular motions lead to dilation of pore space inside the shear band and increases in local permeability. While considerable anisotropy in the contact fabric is observed with the shear band, anisotropy of the permeability is, at most, modest in the assemblies composed of spherical grains.
The Pathology of Treatment Failure
Creators: name: Wilcock, Brian
Publisher: name: American Association of Bovine Practitioners  Proceedings of the Annual Conference
Year: 1988

description: It is implied in the title of this paper that death of a feedlot steer or heifer from pneumonia, despite therapy, is to be viewed as a failure of treatment. While it is true that a dead animal can hardly be touted as a resounding success, it is perhaps equally unreasonable to view fatal termination of an overwhelming bacterial infection as our failure. It is at least equally reasonable to ascribe the death of the animal to hopelessly severe initial disease, to preexistant, concurrent or superimposed complicating diseases, or to mistaken diagnosis and thus inappropriate therapy. In this paper I will review some of the published information relevant to so-called treatment failure, and add to it some of my own opinions based upon postmortem examination of feedlot cattle.

description: Inelastic horizontal sediment deformation from the MS 7.1, 17 October 1989 Loma Prieta earthquake has been estimated to be on the order of 20 cm at a site in Gilroy, California, about 32 km east of the epicenter. This estimate was based on combined deterministic-stochastic simulations using ground motion data and sediment properties measured from in situ seismic tests and laboratory tests on cored sediment samples of up to 170 m deep. The calculated deformation is comparable to measured horizontal coseismic displacements at various stations in the Santa Cruz network, suggesting that previously back-figured fault rupture mechanisms may have been influenced by the coseismic sediment deformation.
A unified method to predict diffuse and localized instabilities in sands

Subjects: subject: Engineering

description: A simplified method to analyse diffuse and localized bifurcations of sand under drained and undrained conditions is presented in this paper. This method utilizes results from bifurcation analysis and critical state plasticity theory to detect the onset of pure and dilatant shear band formation, static liquefaction and drained shear failures systematically. To capture the soil collapse observed in experiments, the instability state line concept originated by Chu, Lo and Lee in 1993 is adopted. Emphasis is given to examine how the presence of pore-fluid may facilitate or delay instability after yielding occurs. The predictions of instabilities are compared with experimental data from triaxial compression tests on Toyoura and Changi sands.

description: We propose a variational procedure for the recovery of internal variables, in effect extending them from integration points to the entire domain. The objective is to perform the recovery with minimum error and at the same time guarantee that the internal variables remain in their admissible spaces. The minimization of the error is achieved by a three-field finite element formulation. The fields in the formulation are the deformation mapping, the target or mapped internal variables and a Lagrange multiplier that enforces the equality between the source and target internal variables. This formulation leads to an L2 projection that minimizes the distance between the source and target internal variables as measured in the L2 norm of the internal variable space. To ensure that the target internal variables remain in their original space, their interpolation is performed by recourse to Lie groups, which allows for direct polynomial interpolation of the corresponding Lie algebras by means of the logarithmic map. Once the Lie algebras are interpolated, the mapped variables are recovered by the exponential map, thus guaranteeing that they remain in the appropriate space.

description: Baryogenesis through neutrino oscillations is an elegant mechanism which has found several realizations in the literature corresponding to different parts of the model parameter space. Its appeal stems from its minimality and dependence only on physics below the weak scale. In this work we show that, by focusing on the physical time scales of leptogenesis instead of the model parameters, a more comprehensive picture emerges. The different regimes previously identified can be understood as different relative orderings of these time scales. This approach also shows that all regimes require a coincidence of time scales and this in turn translates to a certain tuning of the parameters, whether in mass terms or Yukawa couplings. Indeed, we show that the amount of tuning involved in the minimal model is never less than one part in 10^5. Finally, we explore an extended model where the tuning can be removed in exchange for the introduction of a new degree of freedom in the form of a leptophilic Higgs with a vacuum expectation value of the order of GeV.

A description of the selection, breeding, and calving strategies employed by managers and the calculation of monitors of replacement heifer production from breeding to weaning of their first progeny should provide useful comparisons for Ontario farmers and their advisors.

description: Cardiac tissue from swine and canine hearts were assessed using diffuse reflectance near-infrared spectroscopy (NIRS) ex vivo. Slope measured between 800-880 nm reflectance was found to reveal differences between epicardial fat and normal myocardium tissue. This parameter was observed to increase monotonically from measurements obtained from the onset of radio frequency ablation (RFA). A sheathe-style fiber optic catheter was then developed to allow real-time sampling of the zone of resistive heating during RFA treatment. A model was developed and used to extract changes in tissue absorption and reduced scattering based on the steady-state diffusion approximation. It was found that key changes in tissue optical properties occur during application of RF energy and can be monitored using NIRS. These results encourage the development of NIRS integrated catheters for real-time guidance of the cardiac ablation treatment.

description: We report the Sr and Ba isotopic compositions of 18 presolar SiC grains of types Y (11) and Z (7), rare types commonly argued to have formed in lower-than-solar metallicity asymptotic giant branch (AGB) stars. We find that the Y and Z grains show higher 88Sr/87Sr and more variable 138Ba/136Ba ratios than mainstream (MS) grains. According to FRANEC Torino AGB models, the Si, Sr, and Ba isotopic compositions of our Y and Z grains can be consistently explained if the grains came from low mass AGB stars with 0.15 Zsun <= Z < 1.00 Zsun, in which the 13C neutron exposure for the slow neutron-capture process is greatly reduced with respect to that required by MS grains for a 1.0 Z8 AGB star. This scenario is in line with the previous finding based on Ti isotopes, but it fails to explain the indistinguishable Mo isotopic compositions of MS, Y, and Z grains.

Librarians Who Don't Know About Cataloging

Subjects: Library science

description: The subtitle of the book containing this chapter being Library and Information Skills in Social Justice Movements and Beyond, this essay is about informing and empowering library workers with subject expertise in zines (or another special collections area) to do their own cataloging. DIY (do it yourself) is an ethos inherent in the anarchopunk community that produces many of the zines housed in the Barnard Zine Library. Being able to do it yourself, allows a person to take a more active role in activities others are more passive about—healthcare, home projects, crafts, and cooking, so why not cataloging? As a reference librarian, co-author Jenna Freedman could conceive and initiate a collection of zines in her library, but initially she had to turn over the cataloging to someone who had expertise in original cataloging, but no particular knowledge of or interest in zines. Eventually Freedman wore down her colleagues, requested training and then continued learning on her own and with the help of special collections catalogers and zinester-turned-Cataloging/Metadata Librarian Rhonda Kauffman, co-author of this chapter. Kauffman was fluent in both cataloging and zine culture and greatly informed the practice this chapter details.
Signal Reconstruction via H-infinity Sampled-Data Control Theory: Beyond the Shannon Paradigm

description: This paper presents a new method for signal reconstruction by leveraging sampled-data control theory. We formulate the signal reconstruction problem in terms of an analog performance optimization problem using a stable discrete-time filter. The proposed H-infinity performance criterion naturally takes intersample behavior into account, reflecting the energy distributions of the signal. We present methods for computing optimal solutions which are guaranteed to be stable and causal. Detailed comparisons to alternative methods are provided. We discuss some applications in sound and image reconstruction.

description: In this paper we will focus on the results pertaining to the adult breeding herd from breeding season 1986 to calving season 1987. Unless otherwise stated, we will be referring to the randomly selected herds only. We will describe: how beef breeding herds are currently fed, housed, and otherwise managed; what happens to cows between breeding and the birth of a live calf; and what factors influence pregnancy and culling. Most of our work will focus on herd level information, since beef cows in Ontario and elsewhee are managed as herds rather than as individuals.

description: Our bias is that the system should be sufficiently decentralized to meet the major needs of a variety of producers, yet have sufficient centralized planning and data sharing to allow the manipulation and analyses of the volume of data necessary to identify factors influencing health status and to assist in indentifying optimal health management strategies. Indeed the monitoring system and the health management program should be closely integrated. Continuous monitoring can also reveal the extent to which the objectives of health management have been reached. Certainly, the monitoring system should incorporate production data as well as data on disease. It is essential to quantify the effects of disease on production, and it is equally important to realize that the level of production (production efficiency if available) is often the best screening test for health status. In this paper we would like to portray systems that can serve the major needs of individual herd owners and veterinarians, and by data sharing can also meet the needs of provincial and federal governments for large scale monitoring systems.

description: The advent of high-intensity pulsed laser technology enables the generation of extreme states of matter under conditions that are far from thermal equilibrium. This in turn could enable different approaches to generating energy from nuclear fusion. Relaxing the equilibrium requirement could widen the range of isotopes used in fusion fuels permitting cleaner and less hazardous reactions that do not produce high energy neutrons. Here we propose and implement a means to drive fusion reactions between protons and boron-11 nuclei, by colliding a laser-accelerated proton beam with a laser-generated boron plasma. We report proton-boron reaction rates that are orders of magnitude higher than those reported previously. Beyond fusion, our approach demonstrates a new means for exploring low-energy nuclear reactions such as those that occur in astrophysical plasmas and related environments.

description: Bovine mastitis continues as a major disease problem of dairy cattle (1). Improved control is needed to maximize dairymen's profits and to improve the quality of milk to consumers. Development of a single uniform method of control has been difficult as mastitis is not caused by a single pathogen but is a disease involving multiple microorganisms (primarily bacteria) which can and do infect the mammary gland. In reality, mastitis is multiple different diseases occurring in the bovine mammary gland. The primary bacteria associated with mastitis (Table 1) can be grouped according to their primary origin and means of spread within a dairy herd. These pathogen groups are contagious, environmental, and skin flora opportunists. The two major contagious pathogens, Staphylococcus aureus and Streptococcus agalactiae, exist primarily in infected quarters and are spread to uninfected quarters during the milking process. Progress for control of the contagious pathogens has been achieved (2,3). Implementation of post-milking teat end disinfection and total dry cow therapy can eliminate Str. agalactiae from a dairy herd and reduce the prevalance of S. aureus infection to less than 1 % of quarters.
