Powassan virus multiplication in Dermacentor andersoni ticks
Creators: name: Chernesky, Max Alexander
Publisher: name: University of British Columbia
Year: 2011

description: All stages of Dermacentor andersoni (Stiles) ticks were infected by feeding on rabbits injected intravenously with large doses of Powassan virus 48 to 72 hours after the ticks became attached. Viremia titers at least 10²˙⁵ mouse LD₅₀ per ml were required to establish infection in 1 to 5% of ticks ingesting viremic blood. The "infection-threshold" of D. andersoni adults for Powassan virus was elevated when viremia was induced towards the end of engorgement. When each stage in the tick's life cycle was infected a viral-eclipse phase was demonstrated in gut cells. Other organs such as salivary glands, Gene's organ glands and accessory glands supported virus multiplication. This was demonstrated by infectivity titrations and observation of fluorescent foci when the tissues were stained with Powassan virus antiserum conjugated with fluorescein isothiocyanate (FITC). Transstadial transfer of Powassan virus was observed through ecdysis of larvae to nymphs and from nymphs to adults. This occurred both after feeding on hamsters (which produced a substantial viremia) and guineapigs (which did not become viremic). Virus-was detected only in larval gut and invaded nymphal salivary glands during the molt. Infection localized in gut and salivary glands of engorged nymphs and flat adults, and was not detected in adult female accessory and Gene's glands until repletion. Adult males maintained high virus titers in salivary glands only. Transovarial transfer was not detected although infectivity was present on the surface of eggs laid by the mediation of an infected Gene's organ gland. Powassan virus was detected in salivary gland secretions but not in rectal excretions in adults or nymphs. Transmission of Powassan virus to hamsters, guinea-pigs, and rabbits was demonstrated by the bite of D. andersoni nymphs and adults which were infected by ingestion of blood by their antecedent larvae.

description: The study of discrete-time stochastic processes on the half-line with mean drift at $x$ given by $μ_1 (x) \to 0$ as $x \to \infty$ is known as Lamperti's problem. We give sharp almost-sure bounds for processes of this type in the case where $μ_1 (x)$ is of order $x^{-β}$ for some $β\in (0,1)$. The bounds are of order $t^{1/(1+β)}$, so the process is super-diffusive but sub-ballistic (has zero speed). We make minimal assumptions on the moments of the increments of the process (finiteness of $(2+2β+\varepsilon)$-moments for our main results, so 4th moments certainly suffice) and do not assume that the process is time-homogeneous or Markovian. In the case where $x^βμ_1 (x)$ has a finite positive limit, our results imply a strong law of large numbers, which strengthens and generalizes earlier results of Lamperti and Voit. We prove an accompanying central limit theorem, which appears to be new even in the case of a nearest-neighbour random walk, although our result is considerably more general. This answers a question of Lamperti. We also prove transience of the process under weaker conditions than those that we have previously seen in the literature. Most of our results also cover the case where $β=0$. We illustrate our results with applications to birth-and-death chains and to multi-dimensional non-homogeneous random walks.

description: During the 1990-1991 winter, 59 samples of faeces were made in cattle suffering from winter dysentery. These animals were coming from 8 different farms located in 6 different french departments. Each sample has been studied carefully under the electron microscope and put for culture on HRT 18 cells. 32 samples (54%) have shown coronavirus-like viral particles under the microscope. Each group of animals coming from one farm having at least 2 samples found(+) . 6 isolates have been kept from the cells culture and studies after the 9th passage. In these 6 isolates coronavirus were identified with the the help of the electron microscope, their cytopathogenic effect and its seroneutralization, and an direct immunofluorescence method using an anticoronavirus serum prepared on rabbits with a calf diarrhea coronavirus vaccinal strain. These results are in accordance with a participation of this type of virus in the winter dysentery syndrome. Full article in French, English and Spanish summaries on PDF

description: Arginine vasopressin (AVP) or antidiuretic hormone plays a primary role in the regulation of the body fluids. Little is known at present about the regulation of AVP secretion in cattle. Our interest in the regulation of the release of AVP in cattle arises from two basic questions. First, it has been demonstrated recently that administration of AVP to adult ruminants stimulates reticular groove contraction1. This may be of interest, as suggested by others1,2 for the oral administration of drugs that should bypass the ruminoreticulum. No data are available on the role of AVP in the consistent closure of the reticular groove in the young calf. Secondly, pyloric stenos is in cattle results in a metabolic alkalosis. A dehydration occurs, accompanied by a hypochloraemia, a hypokalaemia, a metabolic alkalosis and a uraemia. An extreme dehydration can be found, with a production of diluted urine. No data are available of the plasma AVP concentrations in these cases. To evaluate vasopressin values from patient cases and experimental animals, reference values were collected in 5 normal dairy cows during a water or a salt load.

description: Two series of in-vitro-trials (30 incubations each, 39° C, lasting for 5 hours, nutrients: glucose and urea) were carried out simulating the dosis of 150g and 300g activated charcoal per animal, respectively. The donors of rumen fluid (n=3) were fed hay and concentrate twice a day, water was offered ad libitum. Rumen fluid was sampled 2,5 after feeding and incubated into the artificial rumen immediately. It could be seen that activated charcoal influences the bovine fermentation patterns in vitro dose-depending. The differences and their extend between charcoal-treated rumen fluid and it's controls are listed in the following table. So it is obvious that activated charcoal, given as a therapeutical aid in cattle, influences the ruminal flora significantly and reduces the availability of the VFA relative to their size.

Use of Non Medicated Oral Rehydration Therapy to Treat Diarrhea and Scouring in The Young Calf
Creators: name: Tomkins, Trevor

Publisher: name: American Association of Bovine Practitioners  Proceedings of the Annual Conference
Year: 1992

description: Diarrhea and scouring are still major problems associated with rearing of calves. Calf mortality in the dairy herd may be as high as 15% and much of this is attributable to deaths as a result of dehydration, electrolyte imbalances and physiological starvation, associated with digestive disturbances (diarrhea & scours). Although the use of oral rehydration therapy has been advocated for a long time producers have been slow to move away from reliance on antibiotics to treat diarrhea. Most oral electrolyte products simply aim at replacement of lost ions and perhaps replenishment of some energy with dextrose. Many of these electrolytes have severe imbalances in tonicity resulting in reduced absorption of ions. In addition, few electrolyte products slow rate of passage to prevent further excessive loss of ions through the feces. With these problems in mind, an oral rehydration product (ORP*) was developed and tested in clinical situations. The ORP consisted of a number of ingredients which are common components of diets and oral rehydration products for both animals and humans. These included: energy sources - dextrose, corn syrup solids, lecithin; fibers - to absorb water and slow flow rate in the gut; vegetable gums - to increase viscosity of gut contents to slow rate of passage and aid in suspension of insoluble fibers; electrolytes - sodium, potassium, magnesium. The formulation is proprietary but ingredients were: dextrose, apple flakes, oat hulls, dried corn syrup, xanthan gum, guar gum, vegetable fat, sorbitol, lecithin, sodium bicarbonate, salt, potassium chloride, ascorbic acid, calcium pantothenate, potassium phosphate, dried whey product, magnesium sulfate, polysaccharide complexes of icon, zinc manganese, copper and cobalt, fumaric acid, citric acid, calcium propionate, sodium propionate, potassium sorbate, ethylenediamine dihydriodide, silicon dioxide.

description: Learning and remembering a specific route in advance is benefi-cial to cyclists. As landmarks are known to improve route learning, we tested this in an experiment with 39 participants, where the effect of landmarks dis-played as symbols or pictures is compared to no display of landmarks. Par-ticipants learned the route from a map and had to remember the route. They were shown the route on a video, simulating the bike ride. At decision points the video was stopped, and participants had to give their turning decisions and their confidence. The study revealed no significant differences between the three groups.
Impact of Modern Milk Replacer Formulations on Calf Health and Performance

Year: 1992

description: Within the last ten years there have been major changes in the formulation of calf milk replacers in the United States. These have been brought about by changes in the world supply of milk based ingredients, milk processing technology, vegetable protein processing technology and knowledge of the calf's digestive system. Calf milk replacers manufactured in the 1950's and 1960's contained high levels of skim milk powder as the primary protein source. Skim milk protein consists of approximately 80% casein protein and 20% whey proteins. Provided that the skim milk has not been severely heat treated during the drying process, casein in the milk replacers forms a firm clot or curd in the calf's abomasum. Severely heat treated skim milk does not clot and calves fed milk replacer containing such skim milk suffer from diarrhea and poor performance. Today's modern milk replacers, in the United States, do not contain significant levels of skim milk powder, but either whey proteins or combinations of whey proteins and vegetable proteins, including isolated soy protein, soy protein concentrate, soy flour, isolated wheat protein or potato protein. These milk replacers do not clot in the abomasum and there has been speculation that such non clotting milk replacers may have a negative impact on calf health and performance. Milk Specialties Company has undertaken a series of studies to investigate replacement of skim milk protein in calf milk replacers with whey proteins.

description: Gastro-intestinal disorders constitute the most important findings among an estimated 200.000 neonatal dairy calf mortalities in Denmark (5). Besides infectious diarrhoea, forestomach disturbances play an important role on its own or in combination with general weakness caused by, e.g., diarrhoea. Such disturbances may result from ruminal drinking, from abomaso-ruminal reflux or by forced feeding of weak calves with milk by stomach tube. In any case this leads to disturbed forestomach function, to poor milk utilisation and retarded growth. Reflux may occur in single calves with intestinal obstruction. Management factors which may precipitate reflux are however unknown. In the present experiment the possible role of feeding irregular amounts of milk on the occurrence of reflux is examined in young bucket fed Jersey calves. The investigation was made possible by the recent development of a simple milk coagulation test (4), to be performed on rumen samples, as an indicator of the occurrence of reflux.

The circularly polarized photons, produced from bremsstrahlung of longitudinally polarized electrons, were tagged with the Glasgow magnetic spectrometer. Charged pions and the decay photons of $π^0$ mesons were detected in a $~4π$ electromagnetic calorimeter which combined the Crystal Ball detector with the TAPS detector. The precisely measured asymmetries are very sensitive to details of the production processes and are thus key observables in the modeling of the reaction dynamics.

description: Several conditions may lead to obstruction of the flow of ingesta through the intestinal tract(2,6). Mechanical accidents such as intussusception, volvulus, and strangulation, in which there is a physical occlusion of the intestinal lumen (1,2,4,6). Functional obstructions, such as those which occur with local or general paralytic ileus may mimic mechanical problems.(2,4,6). Congenital malformations may include atresia or constriction of portions of the gut and has been reported in calves and lambs(2,4,6). Compression stenosis by blood clot from an expressed corpus luteum site on an ovary, or traumatic duodenitis caused by migration of a metallic foreign body(2,5). Intestinal carcinoma occurs very rarely in cattle(6). External pressure by mesenteric fat necrosis is a condition of cattle in all dairy, breeds(2,6). Luminal blockages occurs by phytobezoars, and trichobezoars(2,3). The clinical signs of these conditions include a reduction in the amount or a failure to pass feces, progressive abdominal enlargement and colic (2,6).

description: Researchers usually divide counties into the Democratic and the Republican in analyzing human mobility during the COVID-19 pandemic in the US. However, the Swing counties remain a blind spot. Our study reveals that the Swing counties highly resemble the Democratic, but considerably differ from the Republican with respect to the change in mobility volume. People living in the Swing and the Democratic counties consistently reduced traveling during the first wave. Towards the end of it, residents in the Republican counties started increasing traveling. In 2748 out of 3101 counties, the abrupt drop took place on the same day, March 16th, 3 days before the first stay-at-home order. Our findings highlight the role of political affiliation in shaping people's travel behavior and demonstrate the lag in public health policy.

description: As early as 1982, Dutch authors (2) pointed out that loss of contraction of the esophageal groove of initially healthy veal calves causes chronic indigestion (latent chronic ruminal acidosis), so-called "ruminal drinking syndrome." In subsequent years, the etiology of the disease has been studied intensively (6, 7). In advanced stages, the ruminal mucosa of such calves is substantially proliferated and hyperkeratotic. The forestomach disease described by the Munich team (4,5,3), on the other hand, is due to acute complications of primary ailments or is the result of feeding errors. Inborn and acquired "drinking weakness"/anorexia (both have a multitude of causes), as well as force-feeding by stomach tube may cause the esophageal groove to close incompletely or not at all. As a result of this, larger amounts of fluid flow into the rumen and reticulum often followed by an acute ruminal acidosis. The forestomachs of calves diseased in this manner were investigated pathomorphologically in a systematic study (details see 1) that also made note of clinical findings. The results of this investigation will be conveyed below.

description: Abstract

The Khabur River is the main source of water for the city of Zakho. So, the study's goal was to assess its environmental status in order to maximize its usage. In the current study, six sites were chosen to evaluate the microbial pollution indicators, such as Heterotrophic Plate Count (HPC), Total Coliform (TC), Faecal Coliform (FC), and E. coli. Pathogenic bacteria were also isolated directly from the river. The recorded values were ranged as follows: HPC (7.3×102 -780×102 cfu/ml), TC (170-3200 cell/100ml), FC (79-1840 cell/100ml), and E. coli (12-540 cell/100ml). The highest values were recorded in the warm seasons compared to the cold ones, due to the appropriate temperature for bacteria and the frequent use of water by people. It was found that the river is exposed to continuous pollution by pathogenic bacteria as a result of sewage water that is directly discharged into the river and soil erosion on the banks of the river. 129 isolates of bacteria were identified and belonged to 33 species. The Kirby-Bauer disk diffusion procedure was done to examine the susceptibility of isolated bacteria to 21 different antibiotics. The Multiple Antibiotic Resistance (MAR) Index was calculated for the isolated bacteria, and the highest values were found for the bacteria Streptococcus agalactiae, Salmonella typhi, Proteus penneri, Pseudomonas aeruginosa and Aeromonas spp. Also the efficacy of the antibiotics used was determined. Amikacin, ciprofloxacin, Imipenem, Levofloxacin, and Gentamycin were recorded the highest value compared to the rest antibiotics, and their efficacy was 98.41, 97.27, 93.84, 91.66 and 90.9, respectively.

description: Aims. High angular resolution N-band imaging is used to discern the torus of active galactic nuclei (AGN) from its environment in order to allow a comparison of its mid-infrared properties to the expectations of the unified scenario for AGN. Methods. We present VLT-VISIR images of 25 low-redshift AGN of different Seyfert types, as well as N-band SEDs of 20 of them. In addition, we compare our results for 19 of them to Spitzer IRS spectra. Results. We find that at a resolution of ~ 0.35", all the nuclei of our observed sources are point-like, except for 2 objects whose extension is likely of instrumental origin. For 3 objects, however, we observed additional extended circumnuclear emission, even though our observational strategy was not designed to detect it. Comparison of the VISIR photometry and Spitzer spectrophotometry indicates that the latter is affected by extended emission in at least 7 out of 19 objects and the level of contamination is (0.20 ~ 0.85) * F_IRS. In particular, the 10 um silicate emission feature seen in the Spitzer spectra of 6 type I AGN, possibly 1 type II AGN and 2 LINERs, also probably originates not solely in the torus but also in extended regions. Conclusions. Our results generally agree with the expectations from the unified scenario, while the relative weakness of the silicate feature supports clumpy torus models. Our VISIR data indicate that, for low-redshift AGN, a large fraction of Spitzer IRS spectra are contaminated by extended emission close to the AGN.

description: Fatty infiltration of the liver, occurring within 1 to 5 weeks postpartum, and due to excessive lipomobilisation, is the most common liver disease in dairy cows. Case studies showed that 91% of cases with left-sided displacement of the abomasum (LDA), accompanied by suppression of appetite and enhanced lipomobilisation, occurred during this period2. Our experience indicates that nearly 4% of cows with LOA, admitted for surgical treatment, develop hepatic failure in the postoperative period and die in hepatic coma or are slaughterd for that reason3. It has been shown in humans that the plasma activity of Protein C, synthesized in the liver as a Vitamin K-dependant \ anticoagulant factor, decreases in severe liver disease. Therefore, dairy cows suffering from LDA were studied in order to gain information about the correlation between plasma-protein C-activity and hepatic lipidosis.

We also observed the NH3 (1,1) and (2,2) inversion transitions towards the Oph A-N6 peak with the Green Bank Telescope. We have found that the N6 core is composed of shells of different chemical composition due to the freezing out of chemical species at different densities. The undepleted species N2D+ appears to trace the high-density interior of the core, DCO+ and H13CO+ trace an intermediate region, and CS traces the outermost edges of the core. A distinct blue-red spectral asymmetry, indicative of infall motion, is clearly detected in the HCO+ spectra, suggesting that N6 is undergoing gravitational collapse. This collapse was possibly initiated by a decrease in turbulent support suggested by the fact that the non-thermal contribution to the line widths is smaller for the molecular species closer to the center of the core. We also present a temperature profile for the core. These observations support the claim that the Oph A-N6 core is an extremely young prestellar core, which may have been recently cut off from MHD support and begun to collapse.

description: We demonstrate highly efficient generation of coherent 420nm light via up-conversion of near-infrared lasers in a hot rubidium vapor cell. By optimizing pump polarizations and frequencies we achieve a single-pass conversion efficiency of 260% per Watt, significantly higher than in previous experiments. A full exploration of the coherent light generation and fluorescence as a function of both pump frequencies reveals that coherent blue light is generated close to 85Rb two-photon resonances, as predicted by theory, but at high vapor pressure is suppressed in spectral regions that do not support phase matching or exhibit single-photon Kerr refraction. Favorable scaling of our current 1mW blue beam power with additional pump power is predicted.

description: We report magnetic susceptibility, specific heat, and Raman scattering investigations of alpha-TeVO4 containing V-O edge-sharing chains. These chains promote a system of ferromagnetic/antiferromagnetic spin-1/2 Heisenberg alternating exchange chains with pronounced spin frustration. The magnetic susceptibility and Raman scattering evidence a crossover at T* = 85 K with different slopes of the reciprocal susceptibility and a magnetic phase transition into a long-range-ordered state at Tc = 16 K. From Raman scattering data a strong mutual coupling between lattice and magnetic degrees of freedom is deduced. A comparison to model calculations and prior Raman scattering on other chain systems yield a plausible interpretation of the microscopic mechanism for the crossover behavior.
Surgical Correction of Leftsided Abomasal Displacement With a Modified Roll and Suture Method. Success Rate and Condition in Later Lactations

description: The number of abomasal displacements has increased consistently in the last ten years with increasing milk production in a large animal practice in northern Germany despite improved management. Besides disposition (1), and mistakes in management (overfeeding during the dry period, inadequate "steaming up"), it is primarily due to feeding regimes (2) which in this practice include silage of corn, grass or turnip greens, hay, turnips and concentrates. The abomasal displacement has been observed frequently secondary to diseases such as liver disease with ketosis, latent hypocalcemia, abomasitis, pelvic phlegmons, endometritis, and lamenesses with associated general malaise and a decrease in food intake. About half of all abomasal displacements can be cured or disappear spontaneously with fluid therapy, intensive therapy of the underlying disease, change in feeding and peroral therapy (via stomach tube) to improve rumen digestion. If conservative treatment of the patient is not possible, the surgical correction of the abomasal displacement is necessary. Besides the rightsided laparotomy and omentopexy (3), the author used a modification of the method described by HULL (1972) which is fast and simple, and is accepted by many farmers even for the treatment of valuable cows.

description: The research area of photonics deals with all kinds of optical systems used for the generation, manipulation, detection, etc. of signals of light. To be able to compete with modern-day electronics, these systems need to be fabricated from cheap materials on a chip scale using scalable processes. This work introduces a novel all-polymeric and chip-scale platform for such photonic devices. The optical functionality of these devices is based on whispering gallery modes. Additionally, a tunability of at least one optical key characteristic of these systems is aimed for. To achieve this objective, a flexible elastomer that responds to various external stimuli (like heat or illumination) has been incorporated into the all-polymeric building blocks. Thus, certain optical characteristics of these devices can be reversibly controlled via a change of their geometrical properties. The present work deals with the design, fabrication, and characterization of these tunable and all-polymeric photonic systems. At first, the fundamental concept of whispering gallery modes as well as their investigation using fiber-transmission spectroscopy are recapitulated. Afterwards, several novel and scalable fabrication processes of all-polymeric tunable photonic systems are introduced. Finally, two exemplary devices are presented and the tunability of their optical key features is demonstrated in detail.

description: It is very common to blame inheritance as the cause of congenital malformations; however, the majority of defects are caused by environmental factors or by non-inherited chromosomal abnormalities; the latter are mainly developmental accidents. Environmental teratogens act at the time of embrionic implantacion or later. Embrionic or fetal cells undergoing active differenciation are more susceptible.---The most important environmental teratogens are (1): A) Toxic plants; 1- Lupinus spp. 2- Astragalus spp. 3- Conium maculatum, 4- Nicotiana spp. 5- About a dozen of other genus are capable of causing congenital malformations. B) Viruses; 1- Akabane, 2- Other Bunyavirus (Aino, Cache Valley), 3- Blue Tongue, 4- BVD, 5- EEV, and others. C) Physical Factors (e.g. irradiation, temperature). D) Chemicals (e.g. pesticides, anthelmintics). E) Minerals; 1- non-nutrient minerals (e.g. cadmium, lead); 2- nutrient minerals excess or deficiencies (e.g. copper, manganese and zinc deficiencies; excess of selenium). F) Vitamins excess or deficiencies (e.g. vitamin A).

description: Visual Parameter Space Analysis (VPSA) enables domain scientists to explore input-output relationships of computational models. Existing VPSA applications often feature multi-view visualizations designed by visualization experts for a specific scenario, making it hard for domain scientists to adapt them to their problems without professional help. We present RSVP, the Rapid Suggestive Visualization Prototyping system encoding VPSA knowledge to enable domain scientists to prototype custom visualization dashboards tailored to their specific needs. The system implements a task-oriented, multi-view visualization recommendation strategy over a visualization design space optimized for VPSA to guide users in meeting their analytical demands. We derived the VPSA knowledge implemented in the system by conducting an extensive meta design study over the body of work on VPSA. We show how this process can be used to perform a data and task abstraction, extract a common visualization design space, and derive a task-oriented VisRec strategy. User studies indicate that the system is user-friendly and can uncover novel insights.
Perpendicular electron collisions in drift and acoustic wave instabilities

description: Perpendicular electron dynamics and the associated collisions are discussed in relation to the collisional drift wave instability. In addition, the limit of small parallel wave numbers of this instability is studied and it is shown to yield a reduced wave frequency. It is also shown that in this case the growth rate in fact {\em decreases} for smaller parallel wave numbers, instead of growing proportional to $1/k_z^2$. As a result, the growth rate appears to be angle dependent and to reach a maximum for some specific direction of propagation. The explanation for this strange behavior is given. A similar analysis is performed for acoustic perturbations in plasmas with unmagnetized ions and magnetized electrons, in the presence of a density gradient.

description: Aims: In this paper we study density cusps that may contain central black holes. The actual co-eval self-similar growth would not distinguish between the central object and the surroundings. Methods: To study the environment of a growing black hole we seek descriptions of steady `cusps' that may contain a black hole and that retain at least a memory of self-similarity. We refer to the environment in brief as the `bulge' and on smaller scales, the `halo'. Results: We find simple descriptions of the simulations of collisionless matter by comparing predicted densities, velocity dispersions and distribution functions with the simulations. In some cases central point masses may be included by iteration. We emphasize that the co-eval self-similar growth allows an explanation of the black hole bulge mass correlation between approximately similar collisionless systems. Conclusions: We have derived our results from first principles assuming adiabatic self-similarity and either self-similar virialisation or normal steady virialisation. We conclude that distribution functions that retain a memory of self-similar evolution provide an understanding of collisionless systems. The implied energy relaxation of the collisionless matter is due to the time dependence. Phase mixing relaxation may be enhanced by clump-clump interactions.

description: Automatic identification of members of the bovine family is very important in present and future developments of livestock production. From securing export of healthy live animals and meat with genetic superiority to automating health records and production records; automatic identification has the potential to play a significant role in the livestock industry. The technology evaluated is the implantable, passive, electronic identification transponders manufactured by Destron/IDI, of Boulder, Colorado. Transponders were implanted in over 4549 animals during 1991 and 1992 in the United States, Canada and England, evaluating the following: (1.) implanting technique (2.) transponder retention (3.) automation with various animal production systems (4.) carcass identification within the slaughterhouse (5.) slaughterhouse recovery of transponders (6.) disease eradication programs (7.) breed registration (8.) alternative identification to branding and other forms of identification. The above items will be discussed in some detail as related to the trials performed on animals.

description: We have performed Diffusion Quantum Monte Carlo simulations of Li clusters showing that Resonating-Valence-Bond (RVB) pairing correlations between electrons provide a substantial contribution to the cohesive energy. The RVB effects are identified in terms of electron transfers from s- to p-like character, constituting a possible explanation for the breakdown of the Fermi liquid picture observed in recent high resolution Compton scattering experiments for bulk Li.

description: Interoperability is the key to industrial automation. OPC UA aims to provide interoperability between industrial machines at the network, protocol, and semantic layers. In order to achieve it, the implementation of a machine and its nodeset file should comply with the OPC UA standard. However, there are a few areas for improvement in technology to automatically check compliance since the compliance rules/validation rules are expressed in textual format in specification documents. In other words, they are not machine-interpretable. Converting the text-based specification into machine-readable form is a complex problem since each companion specification is domain-specific and written by a set of industry experts from all over the world from diverse language backgrounds. The specifications are majorly unique, with little commonality between them. Because of these reasons, it is challenging to develop a generic information extraction approach to retrieve rules that work for all specifications. In this study, we aim to handle this challenge to extract the textual rules from specifications automatically by applying Natural Language Processing and Machine Learning technologies. We present our methodology based on Named Entity Recognition for OPC UA documents for information extraction and text classification to identify rules. To achieve this goal, we created five named entity data sets from five selected OPC UA companion specifications. The sentences in the data set and the entities in the sentences were annotated by two OPC UA experts. We point out a deeper analysis of the data sets to highlight common and unique entities in them and show their usage in identifying the rules in the specifications.

description: As bovine uterine arterio-venous progesterone (P) levels indicate no differences, P is reportedly not produced in placenta.1,2 However, many documents3-7 have demonstrated and confirmed the P synthesis in tissue cultures of placentae. In contrast to attenuated bovine corpus luteal functions in the later half of gestation,4,8 the P level in blood indicates a substantial increase until near term.9,10 Such an increase in P level at late period of gestation has been attributed to derive from the placenta10,11 and the adrenal. Our present study therefore attempted to investigate P syntheses in both fetal and maternal placentae by measuring the synthesis-related enzyme, 3
