description: Using both an effective three-band model and {\it ab initio} calculations, we have investigated various topological features in the cubic ferromagnetic $5d^{1,2}$ systems showing large spin-orbit coupling (SOC): Ba$_2$NaOsO$_6$, Sr$_2$SrOsO$_6$, and Ba$_2$$B$ReO$_6$ ($B$= Mg, Zn). In the presence of time-reversal symmetry (${\cal T}$), spinless Dirac nodal loops linked to each other at the $W$ points appear in the mirror planes. Remarkably, breaking ${\cal T}$ leads to spinful magnetic Weyl nodal loops (MWNLs) that are robust even at large SOC and correlation strength $U$ variation due to the combination of mirror symmetry and broken ${\cal T}$. Additionally, there are two types of magnetic Weyl points with chiral charges $|χ|=1, 2$ along the $C_{4v}$ symmetry line, and another type-II MWNL encircling the zone center, that are dependent on $U$. Furthermore, the ferromagnetic Ba$_2$ZnReO$_6$ is an ideal half semimetal with MWNLs and magnetic Weyl nodes at the Fermi level without the interference of topologically trivial bulk states. These systems give rise to a remarkably large anomalous Hall conductivity $σ_{xy}$ of up to 1160 ($Ω$cm)$^{-1}$. Our findings may apply widely for $t_{2g}$ systems with cubic (or slightly distorted) fcc-like structures.

description: In Serbia according to the national legislation, 33 species of hoverflies (Diptera, Syrphidae) are declared as strictly protected and 44 species as protected. In addition, Vujić et al. (2016) defined Prime Hoverfly Areas (PHA) and suggested 168 species of hoverflies for protection and designated 91 endemic or endangered species, including 9 species of Eumerus Meigen, 1822 and 11 of Platycheirus Lepeletier & Serville, 1828. The aim of this study was to analyze the environmental niches of Eumerus and Platycheirus species recognized as important for conservation in Serbia. For species of genus Eumerus and Platycheirus, distributional pattern in relation to altitude, annual precipitation and annual mean temperature were established. In order to compare environmental niches of Eumerus and Platycheirus species, Principal components analysis (PCA) was carried out. Results of the analyses showed that Eumerus species have a narrower altitudinal range, with some species found only in the lowland region. They inhabit more arid habitats, and prefer areas with higher annual mean temperatures. In contrast, it was established that most Platycheirus species can be found at higher altitudes with colder climate and that they prefer more humid conditions. Principal Component A analysis indicated partial overlap of the environmental niches of these two genera, but Platycheirus species seemed to be better adapted to harsher conditions.

description: Entropy has become increasingly central to characterize, understand and even guide assembly, self-organization and phase transition processes. In this work, we build on the analogous role of partition functions (or free energies) in isothermal ensembles and that of entropy in adiabatic ensembles. In particular, we show that the grand-isobaric adiabatic $(μ,P,R)$ ensemble, or Ray ensemble, provides a direct route to determine the entropy. This allows us to follow the variations of entropy with the thermodynamic conditions and thus to explore phase transitions. We test this approach by carrying out Monte Carlo simulations on Argon and Copper in bulk phases and at phase boundaries and assess the reliability and accuracy of the method through comparisons with the results from flat-histogram simulations in isothermal ensembles and with the experimental data. Advantages of the approach are multifold and include the direct determination of the $μ-P$ relation, without any evaluation of pressure via the virial expression, the precise control of the system size and of the number of atoms via the input value of $R$, and the straightforward computation of enthalpy differences for isentropic processes, which are key quantities to determine the efficiency of thermodynamic cycles. A new insight brought by these simulations is the highly symmetric pattern exhibited by both systems along the transition, as shown by scaled temperature-entropy and pressure-entropy plots.

The present data is encouraging to look for indirect evidences of physics beyond the Standard Model. We investigate the parameter spaces for different possible Lorentz structures of the new physics four-Fermi interaction. It is shown that if one takes the data at $1σ$ confidence level, only one particular Lorentz structure is allowed. Possible consequences for the $B_s$ system are also discussed.

description: The National Animal Health Monitoring System (NAHMS) is sponsored by the USDA:APHIS:Veterinary Services (VS). The NAHMS Equine '98 Study was designed to provide information about the nation's equine population. Twenty-eight states were included in the study. The USDA's National Agricultural Statistics Service (NASS) collaborated with VS to select a statistically-valid sample such that inferences could be made to all equids and operations with equids in the 28 states. For the purposes of the study, equids included domestic horses, miniature horses, ponies, donkeys/burros, and mules. For Part III of the study, data were collected by Federal and State Veterinary Medical Officers and Animal Health Technicians between March 16, 1998, to April 10, 1998, from 1,178 operations that had 3 or more horses present as of January 1, 1998. Over 94 percent of operations routinely used some form of rodent control; cats were the most common means (77 percent of operations ). Seventy-eight percent of operations had stalls available for horses. Thirty-one percent of operations with stalls used lime on stall floors on a routine basis. Twenty-five percent of operations removed all bedding and manure from a stall once a horse was permanently removed from its stall. Operations with horses primarily used for breeding were more likely to disinfect stalls between horses than were operations with resident horses for other specific uses. Evidence of wildlife in the vicinity was often or sometimes seen on 99 percent of operations. Mice were the animals most frequently seen (on 99 percent of operations) , followed by deer or elk (84 percent of operations ). Fifty-one percent of operations trimmed horses hooves five or more times per year. Thirty-one percent of operations reported the majority of resident horses were not shod; thirty percent of operations reported resident horses were shod 5 or more times in the previous 12 months. Twelve percent of operations reported hospitalization of a resident horse in the previous 12 months. Seventy-three percent of operations never tested for parasites; twenty-two percent of operations tested in response to a clinical problem. Over 95 percent of operations had dewormed the majority of horses in the previous 12 months. Sixty-four percent of operations vaccinated horses less than 12 months of age; nearly 75 percent vaccinated broodmares and other horses over 12 months of age. Across age categories, vaccine against tetanus was most frequently given. Sixty-one percent of operations with broodmares had vaccinated them against influenza in the previous 12 months.

description: A local action is constructed describing the exact string black hole discovered by Dijkgraaf, Verlinde and Verlinde in 1992. It turns out to be a special 2D Maxwell-dilaton gravity theory, linear in curvature and field strength. Two constants of motion exist: mass M>1, determined by the level k, and U(1)-charge Q>0, determined by the value of the dilaton at the origin. ADM mass, Hawking temperature T_H \propto \sqrt{1-1/M} and Bekenstein-Hawking entropy are derived and studied in detail. Winding/momentum mode duality implies the existence of a similar action, arising from a branch ambiguity, which describes the exact string naked singularity. In the strong coupling limit the solution dual to AdS_2 is found to be the 5D Schwarzschild black hole. Some applications to black hole thermodynamics and 2D string theory are discussed and generalizations - supersymmetric extension, coupling to matter and critical collapse, quantization - are pointed out.

description: Introduction

Multiple forms of same enzyme which differ in physical and chemical properties and catalyze the same reaction as an enzyme. Different isoenzymes may arise from different tissues and their specific detection may give clues to the site of pathology. Isoenzymes are produced by a single gene and some may result from more than one gene. Isoenzyme properties include:

•        Catalyze the same reaction.

•        Differ in AA sequence and physical properties.

•        Separable on the basis of charge.

•        Isoenzymes are tissue specific in their nature.

description: Temporal logic has been widely used to express complex task specifications for cyber-physical systems (CPSs). One way to synthesize a controller for CPS under temporal logic constraints is to first abstract the CPS as a discrete transition system, and then apply formal methods. This approach, however, is computationally demanding and its scalability suffers due to the curse of dimensionality. In this paper, we propose a control barrier function (CBF) approach to abstraction-free control synthesis under a linear temporal logic (LTL) constraint. We first construct the deterministic Rabin automaton of the specification and compute an accepting run. We then compute a sequence of LTL formulae, each of which must be satisfied during a particular time interval, and prove that satisfying the sequence of formulae is sufficient to satisfy the LTL specification. Finally, we compute a control policy for satisfying each formula by constructing an appropriate CBF. We present a quadratic program to compute the controllers, and show the controllers synthesized using the proposed approach guarantees the system to satisfy the LTL specification, provided the quadratic program is feasible at each time step. A numerical case study is presented to demonstrate the proposed approach.

description: Many biomedical experiments are carried out by pooling individual biological samples. However, pooling samples can potentially hide biological variance and give false confidence concerning the data significance. In the context of microarray experiments for detecting differentially expressed genes, recent publications have addressed the problem of the efficiency of sample-pooling, and some approximate formulas were provided for the power and sample size calculations. It is desirable to have exact formulas for these calculations and have the approximate results checked against the exact ones. We show that the difference between the approximate and exact results can be large. In this study, we have characterized quantitatively the effect of pooling samples on the efficiency of microarray experiments for the detection of differential gene expression between two classes. We present exact formulas for calculating the power of microarray experimental designs involving sample pooling and technical replications. The formulas can be used to determine the total numbers of arrays and biological subjects required in an experiment to achieve the desired power at a given significance level. The conditions under which pooled design becomes preferable to non-pooled design can then be derived given the unit cost associated with a microarray and that with a biological subject. This paper thus serves to provide guidance on sample pooling and cost effectiveness. The formulation in this paper is outlined in the context of performing microarray comparative studies, but its applicability is not limited to microarray experiments. It is also applicable to a wide range of biomedical comparative studies where sample pooling may be involved.

description: Robustness against small perturbations is a crucial feature of topological properties. This robustness is both a source of theoretical interest and a drive for technological applications, but presents a challenge when looking for new topological systems: Small perturbations cannot be used to identify the global direction of change in the topological indices. Here, we overcome this limitation by breaking the symmetries protecting the topology. The introduction of symmetry-breaking terms causes the topological indices to become non-quantized variables, which are amenable to efficient design algorithms based on gradient methods. We demonstrate this capability by designing discrete and continuous phononic systems realizing conventional and higher-order topological insulators.

description: The shapes of cooperatively rearranging regions in glassy liquids change from being compact at low temperatures to fractal or ``stringy'' as the dynamical crossover temperature from activated to collisional transport is approached from below. We present a quantitative microscopic treatment of this change of morphology within the framework of the random first order transition theory of glasses. We predict a correlation of the ratio of the dynamical crossover temperature to the laboratory glass transition temperature, and the heat capacity discontinuity at the glass transition, Delta C_p. The predicted correlation agrees with experimental results for the 21 materials compiled by Novikov and Sokolov.

Beyond Martyrdom and Anita Prażmowska (2013): Poland: A Modern History As a student at Berkeley, I was once a graduate assistant in a history of modern Europe lecture seminar. The professor was a West Europeanist, although the themes of the seminar bridged both East and West. Throughout the otherwise well-taught seminar, I was struck by the lack of attention on the Polish-Lithuanian Commonwealth or its various permutations after partition. Indeed, Poland offers perhaps one of the best case studies to explore major themes of modern European (and global) history. It was a place where Christianization, the Enlightenment, nationalization and industrialization all took root in various (frequently unexpected) forms. In the twentieth century, particularly, Poland was not only a case study: it was the central theater in Europe where ideologies of various stripe fought each other in word and deed. While the country is usually only treated as a side note in history lectures, three recent publications reveal how central Poland can be in understanding European history. Each book offers different approaches to the grand narrative of this region, and all are revisionist when compared to the traditional story told by conservatives in Poland, even if they vary greatly in the degree of revision. They represent in a nutshell the various ways in which Polish history is being interpreted by academics and the society at large. The first book, by University of Vienna researcher Patrice Dabrowski, takes the first thousand years of Polish history; the second, by London School of Economics and Political Science professor Anita Prażmowska, begins in the nineteenth century; the third, by University of Michigan professor Brian Porter-Szűcs, focuses primarily on the twentieth century. The authors' point of departure arguably frames the way in which they tell the story of Poland.

description: We have developed a sophisticated model of the radio emission from extensive air showers in the scheme of coherent geosynchrotron radiation, providing a theoretical foundation for the interpretation of experimental data from current and future experiments. Having verified the model through comparison of analytic calculations, Monte Carlo simulations and historical experimental data, we now present the results of extensive simulations performed with our Monte Carlo code. Important results are the absence of significant asymmetries in the total field strength emission pattern, the spectral dependence of the radiation, the polarization characteristics of the emission (allowing an unambiguous test of the geomagnetic emission mechanism), and the dependence of the radio emission on important air shower and observer parameters such as the shower zenith angle, the primary particle energy, the depth of the shower maximum and the observer position. An analytic parametrization incorporating the aforementioned dependences summarizes our results in a particularly useful way.

description: The Transiting Exoplanet Survey Satellite mission was designed to find transiting planets around bright, nearby stars. Here we present the detection and mass measurement of a small, short-period ($\approx\,4$\,days) transiting planet around the bright ($V=7.9$), solar-type star HD 86226 (TOI-652, TIC 22221375), previously known to host a long-period ($\sim$1600 days) giant planet. HD 86226c (TOI-652.01) has a radius of $2.16\pm0.08$ $R_{\oplus}$ and a mass of 7.25$^{+1.19}_{-1.12}$ $M_{\oplus}$ based on archival and new radial velocity data. We also update the parameters of the longer-period, not-known-to-transit planet, and find it to be less eccentric and less massive than previously reported. The density of the transiting planet is $3.97$ g cm$^{-3}$, which is low enough to suggest that the planet has at least a small volatile envelope, but the mass fractions of rock, iron, and water are not well-constrained. Given the host star brightness, planet period, and location of the planet near both the ``radius gap'' and the ``hot Neptune desert'', HD 86226c is an interesting candidate for transmission spectroscopy to further refine its composition.

Comparison of neural classifiers and conventional approaches to mode choice analysis
Creators: name: Chow, Stella Yu Wai
Publisher: name: University of British Columbia
Year: 2009

description: This thesis provides a comparison of three modeling techniques which can be used for mode choice analysis. The techniques include the conventional logit, artificial neural networks (ANNs), and neurofuzzy models. The three modeling techniques were applied to mode choice data extracted from the 1999 24-hour trip diary survey of the Greater Vancouver Regional District. The travel mode of each individual was explained using explanatory variables acquired from three categories of the database: household database, personal database, and trip database. The results showed that, as modeling techniques, both ANNs and neurofuzzy models are highly adaptive and very efficient in dealing with problems involving complex interrelationships among many variables. The neurofuzzy technique combines the learning ability of artificial neural networks and the transparent nature of fuzzy logic. In addition; the neurofuzzy technique only selects the variables that significantly influence mode choice and display the stored knowledge in terms of fuzzy linguistic rules. This allows the modal decision making process to be examined and understood in great detail. The results of the comparison also indicated that neurofuzzy models produced the best results in terms of model accuracy. As well, it selected the least number of variables to achieve these results.

description: Książka Katarzyny Kolbowskiej pt. „Capoeira w Polsce. Wędrowanie wątków kulturowych" porusza niezmiernie istotną we współczesnym, zglobalizowanym świecie kwestię treści przenoszonych z kultur rdzennych do kultur im obcych. Treści te „tworzą w ten sposób rozmaite indywidualne bricolage ze zbitek dostępnych im legend, mitów, historycznych faktów, wynajdują tradycję na nowo, dla potrzeb odnalezienia się w zatomizowanym, ponowoczesnym społeczeństwie, by choć na chwilę utwierdzić swoje „ja" w płynnej i niestałej rzeczywistości"(s. 7). W tym kontekście autorka bada egzotyczne, nawiązujące do tradycyjnych kultur-rytuałów, zjawisko – capoeirę, będącą połączeniem tańca, walki, muzyki, folkloru, a także sztuk akrobatycznych. W książce zastosowany został podział na dwie części – czytelnik najpierw ma okazję prześledzić rozdziały teoretyczne, przedstawiające różnorodne aspekty capoeiry, by następnie przejść do przeanalizowania badań terenowych autorki przeprowadzonych na gruncie polskim. Badaczka już od pierwszego rozdziału, mimo niewielu dostępnych źródeł, stara się jak najszerzej nakreślić poszczególne wątki. Wprowadza czytelnika w kontekst socjokulturowy capoeiry, przedstawiając Brazylię jako kraj bogaty w swoistą mozaikę kulturową, pełną przenikających się elementów europejskich, afrykańskich i indiańskich. Autorka podkreśla także rolę kolonialnej przeszłości kraju dla omawianego „zjawiska walki-tańca, będącej rytuałem wspólnotowym, rytuałem wyjścia poza przemoc i walki o wolność, niezależność, autonomię. Walki, która nadaje szlachetny rys manifestacji kulturowej pokrzywdzonej mniejszości" (s. 24).

description: As part of the National Animal Health Monitoring System (NAHMS ), USDA:APHIS:Veterinary Services conducted a national study of beef production, the Beef Cow/Calf Health and Productivity Audit (CHAPA). This study was designed to provide both participants and the industry with information on cow/calf health, productivity, and management practices. Data for Part III: Beef Cow/Calf Health & Health Management were collected by federal and state veterinary officers (VMO's) in 18 of the largest cow/calf producing states between January 4 and February 28, 1993. These 18 states represented 70 percent of the U.S. beef cow inventory. Participating producers had five or more beef cows or beef replacement heifers and fifty percent or more of their 1992 calf crop born between January 1 and June 30, 1992. Nearly forty-seven percent of operations removed bulls from the female breeding herd for at least one estrus cycle to manipulate calving dates. Forty-seven percent of operations that purchased, leased, or borrowed bulls semen tested the bulls. Thirty-two percent of operations fed replacement heifers separately from the rest of the herd. The average per-calf weaning weight of calves weaned in 1992 was 502 pounds; the average value was $451.15. For breeding-age females, the average weight per animal sold was 988 pounds; the average value was $549.44. For breeding-age males, the average weight per animal sold was 1,494 pounds; the average value was $1,154.04. The largest single cause of total cattle death loss was calving problems (26 percent of death loss). Two of the top conditions producers believed had a significant economic impact on the cow/calf operation included internal and external parasites. Other such conditions included late reproduction, pinkeye, and calf scours. Operation-level vaccine usage varied by animal class. Contact for this paper: David Dargatz

description: The existing discrepancy between neutron lifetime measurements in bottle and beam experiments has been interpreted as a sign of the neutron decaying to dark particles. We summarize the current status of this proposal, including a discussion of particle physics models involving such a portal between the Standard Model and a baryonic dark sector. We also review further theoretical developments around this idea and elaborate on the prospects for verifying the neutron dark decay hypothesis in current and upcoming experiments.

description: Anna Cichopek-Gajraj's recent book offers valuable insight into the efforts of Holocaust survivors to rebuild their lives in Poland and Slovakia immediately after the Second World War. Despite the growing scholarship on Holocaust survivors, little attention has been given to survivors' everyday lives in the postwar period. Cichopek-Gajraj is not exaggerating when she states that most of the scholarship has focused on either violence or emigration as far as the Holocaust survivors' experience in Eastern Europe is concerned. The author challenges the dominating narratives. Her book offers insight "beyond violence" into survivors' daily interactions with non-Jewish Poles, Jewish organizations and the Polish or Slovak state administration. With her study on Poland and Slovakia, Anna Cichopek-Gajraj advocates for a comparative approach to post-Holocaust studies. As she argues, it allows for elaborating causal explanations, separating unique phenomena from common ones, and offering a different perspective on events "which remain obscure or ambiguous when examined in the context of a single nation-state" (p. 2). Both Poland and Slovakia witnessed outbreaks of post-war anti-Jewish violence but these countries had also very different pre-war and wartime histories, as well as political settings (p. 3). By comparing Poland and Slovakia, the author studies similar phenomena created under different political and social circumstances. According to the author's own statement, her work situates itself in the middle between public and private (p. 8).

description: The study of the quantum to classical transition is of fundamental as well as technological importance, and focusses on mesoscopic devices, with a size for which either classical physics or quantum physics can be brought to dominate. A particularly diverse selection of such devices is available in cavity quantum-optomechanics. We show that these can be leveraged for the study of dynamical-tunnelling in a quantum chaotic system. This effect probes the quantum to classical transition deeply, since tunnelling rates sensitively depend on the ability of the quantum system to resolve the underlying classical phase space. We show that the effective Planck's constant, which determines this phase space resolution, can be varied over orders of magnitude as a function of tunable parameters in an opto-mechanical experiment. Specifically, we consider a membrane-in-the-middle configuration of a mechanical oscillator within an optical cavity, where the intracavity field is modulated periodically by the external laser source. We demonstrate that a mixed regular and chaotic phase space can be engineered in one spatial dimension, through a significant quartic opto-mechanical interaction. For that case, we explore the expected dynamical tunnelling rates using Floquet theory and map out values of the effective Planck's constant that should be within practical reach.

description: We report on XMM-Newton X-ray observations that reveal CTCV J2056-3014 to be an unusual accretion-powered, intermediate polar (IP) system. It is a member of the class of X-ray-faint IPs whose space density remains unconstrained but potentially very high, with L$_{x,0.3-12 keV}$ of 1.8$\times$10$^{31}$ erg s$^{-1}$. We discovered a coherent 29.6s pulsation in X-rays that was also revealed in our reanalysis of published optical data, showing that the system harbors the fastest-spinning, securely known white dwarf (WD) so far. There is no substantial X-ray absorption in the system. Accretion occurs at a modest rate ($\sim$ 6$\times$10$^{-12}$ M$_{\odot}$ yr$^{-1}$) in a tall shock above the WD, while the star seems to be spinning in equilibrium and to have low magnetic fields. Further studies of CTCV J2056-3014 potentially have broad implications on the origin of magnetic fields in WDs, on the population and evolution of magnetic cataclysmic variables, and also on the physics of matter around rapidly rotating magnetic WDs.

description: There are countless reasons cited in scientific studies to explain the difficulties in programming learning. The reasons range from the subject's complexity, the ineffective teaching and study methods, to psychological aspects such as demotivation. Still, learning programming often boils down to practice on exercise solving. Hence, it is essential to understand that the nature of a programming exercise is an important factor for the success and consistent learning. This paper explores different approaches on the creation of a programming exercise, starting with realizing how it is currently formalized, presented and evaluated. From there, authors suggest variations that seek to broaden the way an exercise is solved and, with this diversity, increase student engagement and learning outcome. The several types of exercises presented can use gamification techniques fostering student motivation. To contextualize the student with his peers, we finish presenting metrics that can be obtained by existing automatic assessment tools.

description: Consolidation in the agricultural biotechnology industry can both enhance and dampen market competition. This report examines the causes and consequences of industry consolidation and its effect on market efficiency. In some cases, concentration realizes economies of scale, which can improve market efficiency by driving down production costs. The protection of intellectual property rights is integral to the agricultural biotechnology marketplace, stimulating research and development, investment, and the development of substitute markets. However, excessively broad intellectual property rights can hinder the market for innovation. Recent data on mergers, acquisitions, and strategic collaborations in the agricultural biotechnology industry, as well as the emergence of "life science" conglomerates, indicate some level of consolidation. However, the move by some companies to divest their seed operations calls into question the long-term viability of these conglomerates.

description: Infrared spectra of the CO2-N2 dimer are observed in the carbon dioxide nu3 asymmetric stretch region (~2350 cm-1) using a tunable infrared optical parametric oscillator to probe a pulsed slit jet supersonic expansion. Previous results for the b-type fundamental band are extended to higher values of Ka. An a-type combination band involving the lowest in-plane intermolecular bending mode is observed. This yields a value of 21.4 cm-1, and represents the first experimental determination of an intermolecular mode for CO2-N2. This intermolecular frequency is at odds with the value of 45.9 cm-1 obtained from a recent 4D intermolecular potential energy surface. In addition, two weak bands near 2337 cm-1 are assigned to the CO2 hot band transition (v1, v2, l2, v3) = (0111)

description: The dynamical mass generation for gluons is discussed in Euclidean Yang-Mills theories supplemented with a renormalizable mass term. The mass parameter is not free, being determined in a self-consistent way through a gap equation which obeys the renormalization group. The example of the Landau gauge is worked out explicitly at one loop order. A few remarks on the issue of the unitarity are provided.

description: Entangled photons produced by spontaneous parametric down-conversion have been of paramount importance for our current understanding of quantum mechanics and advances in quantum information. In this process, the quantum correlations of the down-converted photons are governed by the optical properties of the pump beam illuminating the non-linear crystal. Extensively, the pump beam has been modeled by either coherent beams or by the well-know Gaussian-Schell model, which leads to the natural conclusion that a high degree of optical coherence is required for the generation of highly entangled states. Here, we show that when a novel class of partially coherent Gaussian pump beams is considered, a distinct type of quantum state can be generated for which the amount of entanglement increases inversely with the degree of coherence of the pump beam. This leads to highly incoherent yet highly entangled multi-photon states, which should have interesting consequences for photonic quantum information science.
