description: We report on THz time-domain spectroscopy on multiferroic GeV4S8, which undergoes orbital ordering at a Jahn-Teller transition at 30.5 K and exhibits antiferromagnetic order below 14.6 K. The THz experiments are complemented by dielectric experiments at audio and radio frequencies. We identify a low-lying excitation close to 15 cm-1, which is only weakly temperature dependent and probably corresponds to a molecular excitation within the electronic level scheme of the V4 clusters. In addition, we detect complex temperature-dependent behavior of a low-lying phononic excitation, closely linked to the onset of orbitally-driven ferroelectricity. In the high-temperature cubic phase, which is paramagnetic and orbitally disordered, this excitation is of relaxational character, becomes an overdamped Lorentzian mode in the orbitally ordered phase below the Jahn-Teller transition, and finally appears as well-defined phonon excitation in the antiferromagnetic state. Abrupt changes in real and imaginary parts of the complex dielectric permittivity show that orbital ordering appears via a structural phase transition with strong first-order character and that the onset of antiferromagnetic order is accompanied by significant structural changes, which are of first-order character, too. Dielectric spectroscopy documents that, at low frequencies, significant dipolar relaxations are present in the orbitally ordered, paramagnetic phase only. In contrast to the closely related GaV4S8, this relaxation dynamics that most likely mirrors coupled orbital and polar fluctuations does not seem to be related to the dynamic processes detected in the THz regime.

description: We present a frequency-renormalized multipolaron expansion method to explore the ground state of quantum Rabi model (QRM). The main idea is to take polaron as starting point to expand the ground state of QRM. The polarons are deformed and displaced oscillator states with variationally determined frequency-renormalization and displacement parameters. This method is an extension of the previously proposed polaron concept and the coherent state expansion used in the literature, which shows high efficiency in describing the physics of the QRM. The proposed method is expected to be useful for solving other more complicated light-matter interaction models.

description: No abstracts are to be cited without prior reference to the author.Otolith increment width and larval fish data (length, weight) are used to develop an Individual Based Model (IBM) in order to describe daily resolved larval growth rates of North Sea herring. The model has been utilized for larvae caught during ichthyoplankton surveys from 1990 to 1998. The model combines sagittal otolith readings (core and individual increment measurements), standard length and weight data of larvae, solving an overdetermined set of linear system equations for all parameters using the method of least square residuals. The model consists of a matrix, which describes the increment width formation of more than 140 larvae, a vector containing their length/weight measurements, and a vector describing resi-duals. The solution vector yields age dependent maximum somatic growth rates of herring larvae up to an age of 40 days with sizes ranging from 10 to 25 mm. The observed environmental temperature in which larvae dwelled was relatively uniform. Therefore, measured increment width was individually used to determine daily growth from any single larvae in relation to their potential maximum growth under optimal feeding conditions. The results are discussed with respect to the spatial and temporal variability of larvae occurrence. Finally, an analysis of error estimation of the larval growth characteristics is presented.

description: Given unit execution time (UET) tasks whose precedence constraints form a directed acyclic graph (DAG), the arcs are associated with unit communication time (UCT) delays. The problem is to schedule the tasks on two processors in order to minimize the makespan. Several polynomial algorithms in the literature are proposed for special classes of digraphs, but the complexity of solving this problem in general case stills a challenging open question. We propose in this paper a linear time algorithm to compute an optimal schedule for the class of DAGs of depth two.

description: Conference proceedings are a common source of information for veterinarians. However conference proceedings tend to be brief and not subject to peer review. Studies in human medicine suggest that the results from conference proceedings tend to be "rosier" than subsequent peer reviewed publications suggesting that reliance on conference proceedings may result in an overestimation of efficacy. The objective of this study was to compare results presented in conference proceedings with subsequent publications.

description: Cattle persistently infected (Pl) with bovine viral diarrhea virus (BVDV) are the main viral reservoir of the disease. Despite associations between BVDV and negative health and performance effects, previous research suggests that PI cattle have minimal impact on non-PI cattle. This discrepancy is likely multi-faceted but may suggest that all PI cattle are not equally effective in transmitting BVDV. The objectives of this study were two-fold: (1) to assess differences in BVDV viremia concentrations among multiple PI cattle at one time point, and (2) to determine if BVDV viremia changed over time among PI cattle.

description: A Wireless Sensor Network (WSN) is made up of a large number of nodes that are spread randomly or on a regular basis to detect the surrounding environment and transfer data to a base station (BS) over the Internet to the user. It is widely used in a variety of civil and military concerns. Because the sensor has limited battery capacity, energy efficiency is a critical issue with WSNs. As a result, developing a routing protocol that decreases energy consumption in sensor nodes to extend the lifetime of the WSN using an intelligence algorithm has become difficult. LEACH is the first hierarchical routing protocol that divides the WSN into clusters to reduce energy usage. However, it has reached its limit in selecting a suitable cluster head and the sensor nodes to be joined, as well as their quantity. Thus, this research proposes an algorithm called Wireless Energy Balancing algorithm (WEB) that works on energy balancing distribution by identifying a suitable cluster head with minimum distance and high energy. Then it uses the knapsack-problem as a novel algorithm to design the cluster members. The simulation results demonstrate that the WEB algorithm outperforms LEACH by 31% in terms of energy conservation and WSN lifetime extension.

description: Polariton lasing is the coherent emission arising from a macroscopic polariton condensate first proposed in 1996. Over the past two decades, polariton lasing has been demonstrated in a few inorganic and organic semiconductors in both low and room temperatures. Polariton lasing in inorganic materials significantly relies on sophisticated epitaxial growth of crystalline gain medium layers sandwiched by two distributed Bragg reflectors in which combating the built-in strain and mismatched thermal properties is nontrivial. On the other hand, organic active media usually suffer from large threshold density and weak nonlinearity due to the Frenkel exciton nature. Further development of polariton lasing towards technologically significant applications demand more accessible materials, ease of device fabrication and broadly tunable emission at room temperature. Herein, we report the experimental realization of room-temperature polariton lasing based on an epitaxy-free all-inorganic cesium lead chloride perovskite microcavity. Polariton lasing is unambiguously evidenced by a superlinear power dependence, macroscopic ground state occupation, blueshift of ground state emission, narrowing of the linewidth and the build-up of long-range spatial coherence. Our work suggests considerable promise of lead halide perovskites towards large-area, low-cost, high performance room temperature polariton devices and coherent light sources extending from the ultraviolet to near infrared range.

description: Bovine viral diarrhea viruses (BVDV) are found worldwide, and acute infections in cattle result in enteric, respiratory, and reproductive diseases of varying severity, depending on the BVDV strain, the immune and reproductive status of the host and the presence of secondary pathogens. While most commonly associated with cattle, there is evidence, based on serology and virus isolation, that BVDV replicates in a wide range of cervids. Because free-ranging cervid populations are frequently in contact with domestic cattle in the United States, possible transfer of BVDV between cattle and cervids has significant implication for proposed BVDV control programs. Previous research has demonstrated transmission of BVDV from persistently infected (Pl) deer to cattle and from PI cattle to deer via direct contact [1, 2]. While direct contact between wild cervids and cattle is observed in the field, indirect contact via cervid contamination of feed bunks, salt blocks and pasture is probably more common. Further, although PI animals are a major vector in the introduction of BVDV into naïve herds, circulation of the virus within a population is due, at least in part, to transmission of virus from acutely infected animals. In this study the transmission of BVDV to cattle from acutely infected deer via indirect contact is examined.

description: The electronic properties of single-layer antimony are studied by a combination of first-principles and tight-binding methods. The band structure obtained from relativistic density functional theory is used to derive an analytic tight-binding model that offers an efficient and accurate description of single-particle electronic states in a wide spectral region up to the mid-UV. The strong ($λ=0.34$ eV) intra-atomic spin-orbit interaction plays a fundamental role in the band structure, leading to splitting of the valence band edge and to a significant reduction of the effective mass of the hole carriers. To obtain an effective many-body model of two-dimensional Sb we calculate the screened Coulomb interaction and provide numerical values for the on-site $\bar{V}_{00}$ (Hubbard) and intersite $\bar{V}_{ij}$ interactions. We find that the screening effects originate predominantly from the 5$p$ states, and are thus fully captured within the proposed tight-binding model. The leading kinetic and Coulomb energies are shown to be comparable in magnitude, $|t_{01}|/(\bar{V}_{00}-\bar{V}_{01}) \sim 1.6$, which suggests a strongly correlated character of 5$p$ electrons in Sb. The results presented here provide an essential step toward the understanding and rational description of a variety of electronic properties of this two-dimensional material.

description: Recently, several reviews of clinical trials in preharvest food safety and production animal medicine have identified issues with lack of reporting of key methodological quality features and items necessary for interpretation and replication of trial findings. In human medicine, similar issues with the reporting of clinical trials were identified 10-15 years ago. This led to the publication of the CONsolidated Standards Of Reporting Trials (CONSORT) statement, which consists of a checklist of 22 items that should be reported when publishing a clinical trial, a flow diagram to describe participant movement at all stages of a trial, and an explanation and elaboration document. The CONSORT statement is endorsed by hundreds of medical journals and has resulted in improvements in trial reporting. Livestock clinical trials incorporate issues not covered by CONSORT, including the distinction between animal owners and study subjects, the frequent allocation of treatments to groups, the conduct in both research and commercial settings, and the common use of deliberate disease challenge models.

description: When a magnetic field confines the carriers of a Fermi sea to their lowest Landau level, electron-electron interactions are expected to play a significant role in determining the electronic ground state. Graphite is known to host a sequence of magnetic field-induced states driven by such interactions. Three decades after their discovery, thermodynamic signatures of these instabilities are still elusive. Here, we report the first detection of these transitions with sound velocity. We find that the phase transition occurs in the vicinity of a magnetic field at which at least one of the Landau levels cross the Fermi energy. The evolution of elastic constant anomalies with temperature and magnetic field draws a detailed phase diagram which shows that the ground state evolves in a sequence of thermodynamic phase transitions.Our analysis indicates that electron-electron interaction is not the sole driving force of these transitions and that lattice degrees of freedom play an important role.

description: No abstracts are to be cited without prior reference to the author.Annual variability of female prosome length of the dominant calanoid copepods Acartia clausi, Temora longicornis, Centropages hamatus and Pseudocalanus elongatus in the southern North sea was clearly related to temperature, while egg production was best correlated with body size. A four-year time series of prosome measurements of these species was used to determine the timing of the first appearance of the G1 – generation, to describe interannual variability of body carbon from length-weight relationships, and to predict egg production rate from a weight-egg production relationship established in the field. While maximum and minimum prosome length varied interannually by ca. 10%, body carbon varied by up to 50%. Maximum egg production rate varied by a factor 1.5 to 2. The range in first appearance of the G1 – generation between the 4 years was highest in Acartia clausi with 67 days, in the other species it varied from 30 to 50 days. This should have significant impact on the feeding condition of larval fish. Interannual size variability was not explained by temperature. Other potential controls are discussed.

description: Mastitis in heifers is not uncommon. During the last 20 years, numerous investigations have described the nature of mastitis in heifers (Fox, 2009). Coagulase-negative staphylococci (CNS) are the most prevalent cause of intramammary infections (IMI) in heifers around calving, but Staphylococcus aureus should not be ignored as it is also prevalent, contagious, and more likely to persist into lactation. Some studies have shown a negative impact of an elevated early lactation somatic cell count (SCC) on subsequent test-day SCC, milk production and survival in heifers (De Vleigher et al, 2004-2005). The impact should vary according to the pathogen causing the IMI. The objective of this study was to determine the effect of an IMI caused by CNS or S. aureus diagnosed during the first month of lactation in heifers on SCC, milk production, and culling risk during the first lactation.

description: Nowadays, data is stored on farm with a focus on reproduction, production, and health parameters. Recently, this has been increased with a vast amount of data coming from new so called precision livestock farming (PLF) technologies. These PLF technologies includes rectal, vaginal, and ruminal temperature data loggers, accelerometers, automated weight scales, 3D-imaging technologies and many others. However, they commonly create large data sets, which are stored in on-farm databases that do not reach the veterinary community. The objective of the current initiative is to help re-establish that veterinary link to on-farm data by including large data set analysis in the veterinary curriculum.

description: Recent studies on analyzing dynamic brain connectivity rely on sliding-window analysis or time-varying coefficient models which are unable to capture both smooth and abrupt changes simultaneously. Emerging evidence suggests state-related changes in brain connectivity where dependence structure alternates between a finite number of latent states or regimes. Another challenge is inference of full-brain networks with large number of nodes. We employ a Markov-switching dynamic factor model in which the state-driven time-varying connectivity regimes of high-dimensional fMRI data are characterized by lower-dimensional common latent factors, following a regime-switching process. It enables a reliable, data-adaptive estimation of change-points of connectivity regimes and the massive dependencies associated with each regime. We consider the switching VAR to quantity the dynamic effective connectivity. We propose a three-step estimation procedure: (1) extracting the factors using principal component analysis (PCA) and (2) identifying dynamic connectivity states using the factor-based switching vector autoregressive (VAR) models in a state-space formulation using Kalman filter and expectation-maximization (EM) algorithm, and (3) constructing the high-dimensional connectivity metrics for each state based on subspace estimates. Simulation results show that our proposed estimator outperforms the K-means clustering of time-windowed coefficients, providing more accurate estimation of regime dynamics and connectivity metrics in high-dimensional settings. Applications to analyzing resting-state fMRI data identify dynamic changes in brain states during rest, and reveal distinct directed connectivity patterns and modular organization in resting-state networks across different states.

description: No abstracts are to be cited without prior reference to the author.The dominant copepod taxa on Georges Bank were monitored between January and June of 1995 through 1999, using a pump sampler and a 1-M MOCNESS. Between March and May of these years over 10,000 cod and haddock larvae were collected and recent growth of individual larvae estimated using RNA/DNA ratio analysis. Undertaken as part of the US GLOBEC NW Atlantic Georges Bank Program, the zooplankton sampling was completed on broadscale cruises covering much of the Bank, while most of the larval collections were made on process cruises concentrated on the southern flank. Together the two data sets afforded the opportunity to examine prey production and larval growth over extended spatial and temporal scales. Indices of prey abundance were estimated for different size-classes of larvae. Normalized prey counts (#•M-3) and prey biomass concentration (μg dry weight•M-3) increased between January and May of each year. Following a similar trend, larval growth increased between March and May. The spring of 1995 and to a lesser extent 1996 appeared to be periods of poor growth and low prey availability for cod and haddock larvae on Georges Bank. Although no large year-class of cod was produced during the study period, the 1998 and 1999 year-classes of haddock were among the largest produced over the previous 20 years. Models relating larval growth to size, photoperiod, prey abundance and other environmental variables will be presented.

description: Total serum proteins concentration (TP) is frequently measured in calves to evaluate adequacy of passive transfer of immunoglobulin G (IgG) from colostrum. However, calves fed some commercially available colostrum-derived colostrum replacers (CR) may have lower serum TP at equal IgG concentrations as compared to calves fed maternal colostrum (MC). This can be due to removal of some proteins during manufacturing of CR. The objective of this study was to determine the linear relationship between TP and IgG at 22 to 28 h after birth for CR and MC.

description: Некоторые этапы технологии заключительной отделки текстильных материалов большой толщины и поверхностной плотности – сушка и термофиксация – сопряжены с рядом проблем, особенно при использовании в качестве аппрета растворов водных дисперсий полимеров. Проявляется это в виде миграции частиц дисперсной фазы к поверхности текстильного полотна под действием теплового потока и образованию пленки. Это приводит к ухудшению эксплуатационных и специальных свойств готового изделия. Решением данной проблемы является использование для сушки электромагнитного излучения сверхвысокочастотного диапазона. Проведены исследования процесса сушки и термофиксации текстильных тканых полотен поверхностной плотностью 460 г/м2 из вискозных нитей в среде электромагнитного излучения СВЧ-диапазона. Структурный анализ срезов полученных полотен доказал эффективность применения нового способа термообработки в сравнении с конвективной сушкой.

description: The growth of videos in our digital age and the users' limited time raise the demand for processing untrimmed videos to produce shorter versions conveying the same information. Despite the remarkable progress that summarization methods have made, most of them can only select a few frames or skims, creating visual gaps and breaking the video context. This paper presents a novel weakly-supervised methodology based on a reinforcement learning formulation to accelerate instructional videos using text. A novel joint reward function guides our agent to select which frames to remove and reduce the input video to a target length without creating gaps in the final video. We also propose the Extended Visually-guided Document Attention Network (VDAN+), which can generate a highly discriminative embedding space to represent both textual and visual data. Our experiments show that our method achieves the best performance in Precision, Recall, and F1 Score against the baselines while effectively controlling the video's output length.

description: Minimizing the risk of antibiotic resistant organisms and antibiotic residues in dairy and dairy-beef products is a topic of nationwide interest. Our long term goal is to achieve this objective, based on decreasing unnecessary antibiotic use on dairies. To design an effective outreach program on judicious use of antibiotics, it is imperative to describe the actual practices on dairies. The objective of this study is to describe the identification techniques for sick cows and treatments decisions for fresh cows (FC) based on cow-side observations.

Opening the gate

description: When beginning this project, I had one goal in mind: Showcase ways where college teaching fails and offer a path forward. When teaching college students, professors are not in control of their students’ prior education; some come from high-quality schools while others do not. Yet, often it seems that students are taught the same, which fails some foundational goals of education. Students, to no fault of their own, find themselves locked out of complex material which, ironically, they are most in need of. My proposition is simple: Modify the language of some of our most complex texts in the field of English Studies so that students off all educational backgrounds can benefit from them. In this project, I have included two items. The first, a podcast. This medium not only shapes my argument but is meant to demonstrate one way of modifying texts for easier consumption. Within this portion, we trace why students enter college classrooms underprepared, the problems they will face, and confront the difficulty of college professors acting as gatekeepers instead of guides. The second, a short companion paper explaining process and background research that comprised the project to give others insight into why/how the podcast was created. This project has been created under the same guise it means to propose, meaning, it is meant to be relatively simple to consume. Demonstrating the practice of complex and important arguments and research through simplified composition was employed to keep this project truthful; practicing what it preaches. By the end of this project, the reader/listener should have a more complete understanding of the practice of gatekeeping, the problems it causes for our society, and an outlook for how to help improve higher education.

description: Mental health forums are online communities where people express their issues and seek help from moderators and other users. In such forums, there are often posts with severe content indicating that the user is in acute distress and there is a risk of attempted self-harm. Moderators need to respond to these severe posts in a timely manner to prevent potential self-harm. However, the large volume of daily posted content makes it difficult for the moderators to locate and respond to these critical posts. We present a framework for triaging user content into four severity categories which are defined based on indications of self-harm ideation. Our models are based on a feature-rich classification framework which includes lexical, psycholinguistic, contextual and topic modeling features. Our approaches improve the state of the art in triaging the content severity in mental health forums by large margins (up to 17% improvement over the F-1 scores). Using the proposed model, we analyze the mental state of users and we show that overall, long-term users of the forum demonstrate a decreased severity of risk over time. Our analysis on the interaction of the moderators with the users further indicates that without an automatic way to identify critical content, it is indeed challenging for the moderators to provide timely response to the users in need.

description: Our everyday experience teaches us that the structure of a medium strongly influences how light propagates through it. A disordered medium, e.g., appears transparent or opaque, depending on whether its structure features a mean free path that is larger or smaller than the medium thickness. While the microstructure of the medium uniquely determines the shape of all penetrating light paths, recent theoretical insights indicate that the mean length of these paths is entirely independent of any structural medium property and thus also invariant with respect to a change in the mean free path. Here, we report an experiment that demonstrates this surprising property explicitly. Using colloidal solutions with varying concentration and particle size, we establish an invariance of the mean path length spanning nearly two orders of magnitude in scattering strength, from almost transparent to very opaque media. This very general, fundamental and counterintuitive result can be extended to a wide range of systems, however ordered, correlated or disordered, and has important consequences for many fields, including light trapping and harvesting for solar cells and more generally in photonic structure design.

description: The phenomenon of subpulse drifting may hold the key to understanding the pulsar emission mechanism. Here, we report on new observations of PSR J0034-0721 (B0031-07), carried out with the Murchison Widefield Array at 185 MHz. We observe three distinct drift modes whose "vertical" drift band separations ($P_3$) and relative abundances are consistent with previous studies at similar and higher frequencies. The driftbands, however, are observed to change their slopes over the course of individual drift modes, which can be interpreted as a continuously changing drift rate. The implied acceleration of the intrinsic carousel rotation cannot easily be explained by plasma models based on ExB drift. Furthermore, we find that methods of classifying the drift modes by means of $P_3$ measurements can sometimes produce erroneous identifications in the presence of a changing drift rate. The "horizontal" separation between driftbands ($P_2$) is found to be larger at later rotation phases within the pulse window, which is inconsistent with the established effects of retardation, aberration, and the motion of the visible point. Longer observations spanning at least ~10,000 pulses are required to determine how the carousel rotation parameters change from one drift sequence to the next.
