description: A number of low mass X-ray binaries (LMXBs) undergo "failed outbursts" in which, instead of evolving through the canonical states, they remain in a hard state throughout the outburst. While the sources of X-ray and radio emission in the hard state are relatively well understood, the origin of the near infrared (NIR) and optical emission is more complex though it likely stems from an amalgam of different emission processes, occurring as it does, at the intersecting wavelengths of those processes. We aim to identify the NIR/optical emission region(s) during a number of failed outbursts of one such low mass X-ray binary and black hole candidate, XTE J1550-564, in order to confirm or refute their classification as hard-state, failed outbursts. We present unique NIR/optical images and spectra, obtained with the ESO-New Technology Telescope, during the failed outbursts of 2001 and 2000. We compare the NIR/optical photometric, timing, and spectral properties with those expected for the different emission mechanisms in the various LMXB states. The NIR/optical data are consistent with having come from reprocessing of X-rays in the accretion disk, with no evidence of direct thermal emission from the disk itself. However, the observed variability in high-cadence NIR light curves suggest that the radio jet extends and contributes to the NIR wavelengths. We find that these failed outbursts did not transition to an intermediate state but remained in a true, hard state where there was no sign of jet quenching or deviation from the observed hard state correlations.

description: A diffusive stochastic Schrödinger equation (SSE) is shown for the first time, such that contributes to a non-completely positive dynamics. This contradicts to a recent Letter [arXiv:1303.4284] claiming that SSEs, under most general conditions, enforce complete-positivity. The general form and parametrization of the SSE in the Letter is different from an alternative simpler result, the difference is shown to be completely redundant because of the gauge-freedom of the state vector's phase.

X-ray Absorption of High Redshift Quasars

description: Soft X-ray photoelectric absorption of high-z quasars has been known for two decades, but has no unambiguous astro-physical context. We construct the largest sample to date of 58 high redshift quasars (z > 0.45) selected from the XMM-Newton archive based on a high photon count criterion (> 1800). We measure the optical depth tau at 0.5 keV, and find that 43% of the quasars show significant absorption. We aim to find which physical parameters of the quasars drive their observed absorption, e.g., redshift, radio luminosity, radio loudness, or the X-ray luminosity. We compare the absorption behavior with redshift with the pattern expected if the diffuse intergalactic medium (IGM) is responsible for the observed absorption, and with a comparison sample of gamma ray burst (GRB) X-ray afterglows. Although the z > 2 quasar opacity is consistent with diffuse IGM absorption, many intermediate z (0.45 < z < 2) quasars are not sufficiently absorbed for this scenario, and are appreciably less absorbed than GRBs. Only 10/37 quasars at z < 2 are absorbed, and only 5/30 radio quiet quasars are absorbed. We find a weak correlation between tau and z, and even a weaker correlation between tau and radio luminosity, which leads to the conclusion that although a diffuse IGM origin for the quasar absorption is unlikely, optical depth does seem to increase with redshift, roughly as (1+z)^{2.2+-0.6}, tending at high-z to tau ~ 0.4, similar to the high-z GRB values. This result can be explained by an ionized and clumpy IGM at z < 2, and a cold, diffuse IGM at higher redshift. If, conversely, ascribed to local absorption at the quasar, and owing to the steep L_x ~ (1+z)^{7.1+-0.5} correlation in the present sample, the host column density scales as N_H ~ L_x^{0.7+-0.1}.

description: In this work, we propose a sim2real method to transfer and adapt a nonlinear model predictive controller (NMPC) from simulation to the real target system based on executable digital twin (xDT). The xDT model is a high fidelity vehicle dynamics simulator, executable online in the control parameter randomization and learning process. The parameters are adapted to gradually improve control performance and deal with changing real-world environment. In particular, the performance metric is not required to be differentiable nor analytical with respect to the control parameters and system dynamics are not necessary linearized. Eventually, the proposed sim2real framework leverages altogether online high fidelity simulator, data-driven estimations, and simulation based optimization to transfer and adapt efficiently a controller developed in simulation environment to the real platform. Our experiment demonstrates that a high control performance is achieved without tedious time and labor consuming tuning.

description: We construct composite maps of surface-wave arrival-angle anomalies using clustered earthquakes and an array method for measuring wave-front geometry. This results in observations of arrival angles covering the entire footprint of the USArray Transportable Array during 2006–2010. Bands of arrival-angle deviations in the propagation direction indicate the presence of heterogeneous velocity structure both inside and outside of the array. We compare the observed patterns to arrival angles predicted using two global tomographic models, the mantle model S362ANI and the surface-wave-dispersion model GDM52. We use both ray-theory-based prediction methods and measurements on synthetic data calculated using a spectral-element method. Both models and all prediction methods produce similar mean arrival angles and long-wavelength patterns of anomalies which are similar to the observations. Predicted short-wavelength features generally do not agree with the observations. The spectral-element method produces some complexity that is not obtained using the ray-theory-based methods; this predicted complexity is similar in character to the observed patterns, but does not match them.

description: In this article we show that non-singular quadrics and non-singular Hermitian varieties are completely characterized by their intersection numbers with respect to hyperplanes and spaces of codimension 2. This strongly generalizes a result by Ferri and Tallini \cite{FT} and also provides necessary and sufficient conditions for quasi-quadrics (respectively their Hermitian analogues) to be non-singular quadrics (respectively Hermitian varieties).} \section{Introduction} When Segre \cite{Segre} proved his celebrated characterization of conics ("every set of $q+1$ points in $\mathrm{PG}(2,q)$, $q$ odd, no three of which are collinear, is a conic"), he did more than proving a beautiful and interesting theorem; he in fact provided the starting point of a new direction in combinatorial geometry. In this branch of combinatorics the idea is to provide purely combinatorial characterizations of objects classically defined in an algebraic way. This article wants to contribute to this theory by proving strong characterizations of classical finite polar spaces.
Evidence for Infalling Gas of Low Angular Momentum towards the L1551 NE Keplerian Circumbinary Disk

description: We report follow-up observations of the Class I binary protostellar system L1551 NE in the C18O (3--2) line with the SMA in its compact and subcompact configurations. Our previous observations at a higher angular resolution in the extended configuration revealed a circumbinary disk exhibiting Keplerian motion. The combined data having more extensive spatial coverage (~140 - 2000 AU) verify the presence of a Keplerian circumbinary disk, and reveals for the first time a distinct low-velocity (~< +-0.5 km s-1 from the systemic velocity) component that displays a velocity gradient along the minor axis of the circumbinary disk. Our simple model that reproduces the main features seen in the Position-Velocity diagrams comprises a circumbinary disk exhibiting Keplerian motion out to a radius of ~300 AU, beyond which the gas exhibits pure infall at a constant velocity of ~0.6 km s-1. The latter is significantly smaller than the expected free-fall velocity of ~2.2 km s-1 onto the L1551 NE protostellar mass of ~0.8 Msun at ~300 AU, suggesting that the infalling gas is decelerated as it moves into regions of high gas pressure in the circumbinary disk. The discontinuity in angular momenta between the outer infalling gas and inner Keplerian circumbinary disk implies an abrupt transition in the effectiveness at which magnetic braking is able to transfer angular momentum outwards, a result perhaps of the different plasma beta and ionization fractions between the outer and inner regions of the circumbinary disk.

description: The ultralong distance coupling between two Asymmetric Resonant Microcavities (ARCs) is studied. Different from traditional short distance tunneling coupling between microcavities, the high efficient free space directional emission and excitation allow ultralong distance energy transfer between ARCs. In this paper, a novel unidirectional emission ARC, which shows directionality I40 = 0.54, is designed for materials of refractive index n = 2.0. Compared with regular whispering gallery microresonators, the coupled unidirectional emission ARCs show modulations of resonance frequency and linewidth even when the distance between cavities is much longer than wavelength. The performances and properties of the ultralong distance interaction between ARCs are analyzed and studied by coupling mode theory in details. The ultralong distance interaction between ARCs provides a new way to free-space based optical interconnects between components in integrated photonic circuits.

description: Scanning micro-Raman spectroscopy has been utilized to image and investigate strain in He+-implanted congruent LiNbO3 samples. By using abruptly patterned implanted samples, we show that the spatial two-dimensional mapping of the Raman spectral peaks can be used to image the strain distribution and determine its absolute magnitude. We demonstrate that both short- and long-range length-scale in-plane and out-of-plane strain and stress states can be determined using the secular equations of phonon-deformation-potential theory. We also show that two-dimensional Raman imaging can be used to visualize the relaxation of strain in the crystal during low-temperature annealing.

description: Idaho has added trichomoniasis to its reportable and regulatory diseases. Since the early eighties trichomoniasis has been diagnosed with increasing frequency in Idaho, particularly in areas that practice common grazing. The producers that have suffered economic loss due to trichomoniasis and have started control programs, have often failed due to reinfection from infected, but undiagnosed herds in the area. The Idaho Cattle Association mandated that trichomoniasis be reported and regulated. The following regulation became effective on October 6, 1989.

description: Eight years ago the fed beef industry started work on a quality assurance program that joined the efforts of the professional cattle feeder, professional beef cattle consulting veterinarian and the U.S.D.A-F.S.I.S.. Five states (Kansas, Nebraska, New Mexico, Oklahoma, and Texas) and the National Cattlemen's Asso. were involved. The first "verified control program" for cattle production was certified in Oklahoma at Hitch Enterprises three years later. From these beginnings the back bone of what now seems to be a nationally accepted program for quality assurance has been developed. These guide lines have now been accepted by cattlemen in three states. These are voluntary guide lines that are business based, that means practices that are considered part of normal good business practice in accounting, inventory control, and efficient production.

description: The cores of neutron stars harbor the highest matter densities known to occur in nature, up to several times the densities in atomic nuclei. Similarly, magnetic field strengths can exceed the strongest fields generated in terrestrial laboratories by ten orders of magnitude. Hyperon-dominated matter, deconfined quark matter, superfluidity, even superconductivity are predicted in neutron stars. Similarly, quantum electrodynamics predicts that in strong magnetic fields the vacuum becomes birefringent. The properties of matter under such conditions is governed by Quantum Chromodynamics (QCD) and Quantum Electrodynamics (QED), and the close study of the properties of neutron stars offers the unique opportunity to test and explore the richness of QCD and QED in a regime that is utterly beyond the reach of terrestrial experiments. Experimentally, this is almost virgin territory.

description: We study the dynamics of chiral SU(N) gauge theories. These contain Weyl fermions in the symmetric or anti-symmetric representation of the gauge group, together with further fermions in the fundamental and anti-fundamental. We revisit an old proposal of Bars and Yankielowicz who match the 't Hooft anomalies of this theory to free fermions. We show that there are novel and, in some cases, quite powerful constraints on the dynamics in the large N limit. In addition, we study these SU(N) theories with an extra Weyl fermion transforming in the adjoint representation. Here we show that all 21 't Hooft anomalies for global symmetries are matched with those of a Spin(8) gauge theory. This suggests a non-supersymmetric extension of the duality of Pouliot and Strassler. Finally, we also discuss some non-supersymmetric dualities with vector-like matter content for SO(N) and Sp(N) gauge theories and the constraints imposed by Weingarten inequalities.

description: The Poincaré-covariant quantum-field-theoretic description of bound states by the homogeneous Bethe-Salpeter equation usually exhibits an intrinsic complexity that can be attenuated by allowing this formalism to undergo various simplifications. The resulting approximate outcome's reliability can be assessed by applying several rigorous constraints on the nature of the bound-state spectra; most prominent here are existence, number and location of discrete eigenvalues.

description: Bawang putih merupakan jenis tanaman yang biasa ditanam di dataran tinggi tropis yang sangat sensitif terhadap cekaman kekeringan. Kekurangan air dapat menyebabkan pembentukan umbi terhambat sehingga akan mengurangi hasil poduksi. Penelitian iini bertujuan untuk membuat sebuah perangkat yang mampu mengotomatisasi proses penyiraman tanaman bawang putih . Proses penyiraman bawang putih secara manual memakan waktu yang signifikan karena harus dikerjakan secara individual untuk setiap pohon. Perangkat ini dirancang untuk memberikan manfaat dengan memudahkan pekerjaan manusia dalam menyirami bawang putih. Pendekatan yang digunakan dalam penelitian ini adalah Metode Penelitian dan Pengembangan (R&D). Perangkat ini dilengkapi dengan sensor kelembaban tanah yang berperan sebagai pengecek tingkat kelembaban dan mengirim instruksi kepada Arduino Uno untuk mengaktifkan driver relay, sehingga pompa air untuk melakukan penyiraman otomatis sesuai kebutuhan. Penelitian ini meliputi perancangan, serta implementasi komponen-komponen sistem, termasuk penggunaan Arduino Uno sebagai pengendali dan driver relay untuk mengatur aktivitas pompa air. Data dari penelitian memastikan bahwa perangkat yang dibuat berfungsi secara efektif, di mana relay akan beroperasi dan mengaktifkan pompa ketika tingkat kelembaban tanah di bawah 40%. Sebaliknya, relay akan berhenti beroperasi ketika kelembaban tanah mencapai lebih dari 40%. Agar dapat berproduksi optimal bawang putih memerlukan volume dan interval penyiraman yang tepat.
Pharyngeal Lacerations and Retropharyngeal Abscesses in Cattle

description: Injuries of the oro-pharynx are most often associated with trauma due to balling guns, Frick speculums, drench syringes or the boluses themselves.1 Often the operator has no idea that an injury has occurred until several days later when the cow's inappetance/throat swelling has become apparent. Although many lacerations are small and heal spontaneously with minimal clinical signs, identifiable pharyngeal lacerations cause much distress to affected cattle resulting in significant weight loss and/or death. The following is a summary of 17 cases of pharyngeal laceration/retropharyngeal abscess seen at the Ohio State University Veterinary Teaching Hospital (table 1). Clinical signs seen in cattle found to have pharyngeal lacerations included dyspnea (11), excessive salivation (7), high cervical swelling (7), anorexia (7), bloat (1) and malodorous breath (1). The respiratory signs in these animals were primarily upper respiratory in nature although pneumonia was also detected in several animals. The degree of respiratory embarrassment in 2 cattle was severe enough to warrant tracheostomy.

description: A listener who recognizes a talker notices characteristic attributes of the talker's speech despite the novelty of each utterance. Accounts of talker perception have often presumed that consistent aspects of an individual's speech, termed indexical properties, are ascribable to a talker's unique anatomy or consistent vocal posture distinct from acoustic correlates of phonetic contrasts. Accordingly, the perception of a talker is acknowledged to occur independently of the perception of a linguistic message. Alternatively, some studies suggest that attention to attributes of a talker includes indexical linguistic attributes conveyed in the articulation of consonants and vowels. This investigation sought direct evidence of attention to phonetic attributes of speech in perceiving talkers. Natural samples and sinewave replicas derived from them were used in three experiments assessing the perceptual properties of natural and sine-wave sentences; of temporally veridical and reversed natural and sine-wave sentences; and of an acoustic correlate of vocal tract scale to judgments of sine-wave talker similarity. The results revealed that the subjective similarity of individual talkers is preserved in the absence of natural vocal quality; and that local phonetic segmental attributes as well as global characteristics of speech can be exploited when listeners notice characteristics of talkers.

description: We construct a flux-limited sample of 135 candidate z~1 Lya emitters (LAEs) from Galaxy Evolution Explorer (GALEX) grism data using a new data cube search method. These LAEs have luminosities comparable to those at high redshifts and lie within a 7 Gyr gap present in existing LAE samples. We use archival and newly obtained optical spectra to verify the UV redshifts of these LAEs. We use the combination of the GALEX UV spectra, optical spectra, and X-ray imaging data to estimate the active galactic nucleus (AGN) fraction and its dependence on Lya luminosity. We remove the AGNs and compute the luminosity function (LF) from 60 z~1 LAE galaxies. We find that the best fit LF implies a luminosity density increase by a factor of ~1.5 from z~0.3 to z~1 and ~20 from z~1 to z~2. We find a z~1 volumetric Lya escape fraction of 0.7+/-0.4%.

description: The SSH protocol is commonly used to access remote systems on the Internet, as it provides an encrypted and authenticated channel for communication. If upon establishing a new connection, the presented server key is unknown to the client, the user is asked to verify the key fingerprint manually, which is prone to errors and often blindly trusted. The SSH standard describes an alternative to such manual key verification: using the Domain Name System (DNS) to publish the server key information in SSHFP records. In this paper, we conduct a large-scale Internet study to measure the prevalence of SSHFP records among DNS domain names. We scan the Tranco 1M list and over 500 million names from the certificate transparency log over the course of 26 days. The results show that in two studied populations, about 1 in 10,000 domains has SSHFP records, with more than half of them deployed without using DNSSEC, drastically reducing security benefits.

description: While a thorough history and physical examination remain the foundation of clinical diagnosis, there are times when additional procedures are indicated for establishment of the diagnosis, differentiation of similar conditions/ diseases or prognosis of an established diagnosis. Many of these procedures are not done routinely and thus, the veterinarian may be unsure of the technique. The purpose of this paper is to review the indications, landmarks and procedural techniques used to perform cerebrospinal fluid collection, percutaneous liver biopsy, transtracheal aspiration biopsy (tracheal wash) and abdominal paracentesis in cattle.

We establish a set of functional relations which include a transfer matrix inversion identity. The solution of these relations in the thermodynamic limit allows us to compute the partition function per site of the fundamental $Sp(4)$ representation of the vertex model. As a byproduct we also obtain the partition function per site of a vertex model mixing the four and five dimensional representations of the $Sp(4)$ symmetry.

Using tools based on the geometry of quantum evolutions through the quantum adiabatic brachistochrone, we show that high fidelity control of the ground state of critical quantum systems can be achieved and requires only a reasonable approximation for the ground state spectral gap. We demonstrate our results for three widely applicable systems: the Landau-Zener, Ising, and fully connected spin models.

Separability from Spectrum for Qubit-Qudit States

description: The separability from spectrum problem asks for a characterization of the eigenvalues of the bipartite mixed states ρ with the property that U^*ρU is separable for all unitary matrices U. This problem has been solved when the local dimensions m and n satisfy m = 2 and n <= 3. We solve all remaining qubit-qudit cases (i.e., when m = 2 and n >= 4 is arbitrary). In all of these cases we show that a state is separable from spectrum if and only if U^*ρU has positive partial transpose for all unitary matrices U. This equivalence is in stark contrast with the usual separability problem, where a state having positive partial transpose is a strictly weaker property than it being separable.

description: Despite many efforts the origin of a ferromagnetic (FM) response in ZnMnO and ZnCoO is still not clear. Magnetic investigations of our samples, not discussed here, show that the room temperature FM response is observed only in alloys with a non-uniform Mn or Co distribution. Thus, the control of their distribution is crucial for explanation of contradicted magnetic properties of ZnCoO and ZnMnO reported till now. In the present review we discuss advantages of the Atomic Layer Deposition (ALD) growth method, which enables us to control uniformity of ZnMnO and ZnCoO alloys. Properties of ZnO, ZnMnO and ZnCoO films grown by the ALD are discussed.

description: In this letter, we study a rate-splitting multiple access (RSMA)-based intelligent reflecting surface (IRS)-aided multi-user multiple-input single-output (MISO) secure communication system with a potential eavesdropper (Eve). Aiming to maximize the minimum secrecy rate (SR) among all the legitimate users (LUs), a design problem for jointly optimizing the transmit beamforming with artificial noise (AN), the IRS beamforming, and the secrecy common rate allocation is formulated. Since the design problem is highly non-convex with coupled optimization variables, we develop a computationally efficient algorithm based on the alternating optimization (AO) technique to solve it suboptimally. Numerical results demonstrate that the proposed design can significantly improve the max-min SR over the benchmark schemes without IRS or adopting other multiple access techniques. In particular, employing the RSMA strategy can substantially reduce the required numbers of IRS elements for achieving a target level of secrecy performance compared with the benchmark schemes.

description: Acute respiratory distress is a common problem to the bovine practitioner. Acute respiratory distress can be categorized into upper respiratory disease or lower respiratory disease. Since dyspnea is the primary clinical sign in cases of acute respiratory distress, any condition that can cause dyspnea can cause clinical signs suggestive of respiratory disease. There are also nonrespiratory causes of apparent acute respiratory disease in cattle.

description: The Planck distribution of photons emitted by a black body led to the development of quantum theory. An analogous distribution of phonons should exist in a Bose-Einstein condensate. We observe this Planck distribution of thermal phonons in a 3D condensate. This observation provides an important confirmation of the basic nature of the condensate's quantized excitations. In contrast to the bunching effect, the density fluctuations are seen to increase with increasing temperature. This is due to the non-conservation of the number of phonons. In the case of rapid cooling, the phonon temperature is out of equilibrium with the surrounding thermal cloud. In this case, a Bose-Einstein condensate is not as cold as previously thought. These measurements are enabled by our in situ k-space technique.

description: Ketosis has been a recognized problem in dairy cattle since the late 1920's when the role of glucose and energy demands were first associated with this condition.1 Descriptions of a disease syndrome, now thought to be ketosis, characterized by anorexia, decreased milk production, and constipation appeared in veterinary texts 50 years prior to this.2,3 A more complex type of ketosis was recognized by Sollman4 and Alston5 which, unlike simple ketosis, was associated with high mortality and a variety of concurrent disease problems. Morrow6 called this disease "Fat Cow Syndrome" based on the physical condition of affected cattle. Like simple ketosis, the disease occurred at or around parturtion. The typical histologic lesion common to these affected cows was severe fatty infiltration of the liver (hepatic lipidosis). This same finding (hepatic lipidosis) is not only found in overly conditioned cattle but also in poorly conditioned animals during the periparturient period. As with the Fat Cow Syndrome cows, these cattle also suffer from a variety of concurrent diseases.

description: In the frame of the search for extrasolar planets and brown dwarfs around early-type main-sequence stars, we present the detection of a giant planet around the young F-type star HD113337. We estimated the age of the system to be 150 +100/-50 Myr. Interestingly, an IR excess attributed to a cold debris disk was previously detected on this star. The SOPHIE spectrograph on the 1.93m telescope at Observatoire de Haute-Provence was used to obtain ~300 spectra over 6 years. We used our SAFIR tool, dedicated to the spectra analysis of A and F stars, to derive the radial velocity variations. The data reveal a 324.0 +1.7/-3.3 days period that we attribute to a giant planet with a minimum mass of 2.83 +- 0.24 Mjup in an eccentric orbit with e=0.46 +- 0.04. A long-term quadratic drift, that we assign to be probably of stellar origin, is superimposed to the Keplerian solution.

description: Recent transformer-based offline video instance segmentation (VIS) approaches achieve encouraging results and significantly outperform online approaches. However, their reliance on the whole video and the immense computational complexity caused by full Spatio-temporal attention limit them in real-life applications such as processing lengthy videos. In this paper, we propose a single-stage transformer-based efficient online VIS framework named InstanceFormer, which is especially suitable for long and challenging videos. We propose three novel components to model short-term and long-term dependency and temporal coherence. First, we propagate the representation, location, and semantic information of prior instances to model short-term changes. Second, we propose a novel memory cross-attention in the decoder, which allows the network to look into earlier instances within a certain temporal window. Finally, we employ a temporal contrastive loss to impose coherence in the representation of an instance across all frames. Memory attention and temporal coherence are particularly beneficial to long-range dependency modeling, including challenging scenarios like occlusion. The proposed InstanceFormer outperforms previous online benchmark methods by a large margin across multiple datasets. Most importantly, InstanceFormer surpasses offline approaches for challenging and long datasets such as YouTube-VIS-2021 and OVIS. Code is available at https://github.com/rajatkoner08/InstanceFormer.
Tracheal Collapse and Stenosis of Calves

description: Tracheal collapse and/or stenosis on calves, while undoubtedly not a new condition is being more frequently recognized as a potential cause of severe respiratory distress. The condition is routinely associated with anterior rib fractures which have occurred during dystocia. The calves generally exhibit normal health until fracture healing is advanced. Bone callus formation at or near the thoracic inlet impairs development of the trachea or exerts sufficient pressure to cause collapse of the tracheal lumen.

Surgery for Urolithiasis

description: Urolithiasis is an important disease of male ruminants of all species. It is an especially prevalent disease of castrated males, but is probably much more devastating in the breeding male. The immediate problem is the complete obstruction of the urethra and the inability to urinate, however, one must always remember the secondary sequallae such as skin sloughs, chemical peritonitis, abdominal adhesions and hydronephrosis or hydroureter. Although agents such as aminopromazine have been used to relax urethral spasm with some degree of success, the primary treatment for obstructive urolithiasis is surgical intervention. For any degree of success with medical therapy the animal must not be completely obstructed and must still be dripping some urine.

description: Before considering surgery for the urine pooler one must first understand why urine pooling is detrimental and what constitutes a diagnosis of a urine pooler. Doing surgery for a urine pooler is of no benefit if the cow has other pathology which is causing her infertility unless these other problems are treated concurrently or in place of urine pooler surgery.

Year: 1989

description: In treating ocular squamous cell carcinoma in cattle, certainly enucleation or exenteration have been the time honored methods of choice. In many cases they may still be the methods of choice, however, as they leave a unilaterally blind animal, other less radical methods of therapy should be used whenever possible. Less radical therapeutic approaches should include: 1) immunotherapy, 2) cryosurgery, 3) radiofrequency hyperthermia, 4) Beta radiation, and 5) surgical removal of the tumor tissue without complete enucleation.

description: In \cite{ThasHVM}, a characterization of the finite quadric Veronesean $\mathcal{V}_{n}^{2^{n}}$ by means of properties of the set of its tangent spaces is proved. These tangent spaces form a {\em regular generalised dual arc}. We prove an extension result for regular generalised dual arcs. To motivate our research, we show how they are used to construct a large class of secret sharing schemes.

description: The previous speakers at this general session, "Consumer Concerns, Producer Demands, the Veterinarian's Responsibility", have provided you with a comprehensive overview of the generic subject of food safety from the view of drug use in bovines and as it applies to the bovine practitioner. It remains for me to provide you with an overview of organized veterinary medicine's role in providing for the interests of practitioners in this scenario. For purposes of this discussion, organized veterinary medicine is defined to mean the American Veterinary Medical Association (AVMA) and all of the constituent and allied organizations which legislatively govern AVMA through actions of its House of Delegates (HoD). The American Association of Bovine Practitioners (AABP) delegate to this body is Dr. Bob Keith; alternate delegate is Dr. Harold Amstutz.

description: It is an opportune time to reflect on the VM/AC activity inasmuch as four years have elapsed since the recreated committee convened. I was privileged to serve this first committee as chairman. My selection indicates in part the confidence CVM places in the AABP. The committee was very active during the years I served as chairman. I think it acted in a manner which has been helpful to the agency as well as the regulated industries and the American public. The issues considered by the committee were primarily requested from CVM. The following is a recap of some of the issues discussed by the committee along with its recommendations. The committee was asked to consider the efficacy and labeling requirement for antimicrobial agents used in veterinary medicine. The committee discussed the extra-label use of drugs in food producing animals and made the following reommendations. The committee was asked to consider ways to improve the credibility and respect for the prescription veterinary legend. The committee was asked to critique a revision of the Rx/OTC labeling policies for Rx and OTC drugs. The committee recommended that products be approved only as Rx or OTC with none labeled as both, but if dual labeling was necessary, that CVM provide all label claims in the Rx product label for those products which are approved for both Rx and OTC designation. The committee was asked to consider the criteria for determining Rx/OTC designation.
