Acidosis

description: Sub-acute ruminal acidosis (SARA), a disorder characterized by chronic low ruminal pH, occurs in feedlot cattle fed high-concentrate diets. Forages slow digestion and reduce acid production. Thus, we aimed to assess how motivated finishing cattle are to access forage (Sudan grass hay, SG) via their willingness to interact with an electrified barrier. Reticulorumen pH was measured to contextualize the results with digestive health. Twenty-eight animals fed a high-concentrate ration ad-libitum had access to 4 L one of two treatments (n=14/treatment) fed once a day behind a barrier: 1) SG, or 2) an additional offering of the normal ration (TMR). To access a treatment, the steer voluntarily pushed his muzzle against an electrified barrier. The electrical current was increased exponentially every 24 h (0, 156, 312, 625, 1250, 2500, 5000 µA) until the animal ceased accessing it. Visits to the treatment were recorded continuously 24 h/d and reticulorumen pH was measured every 10 min. Rumen pH averaged 3.0±1.2 and 2.3±0.9 h/d below 5.6, for SG and TMR, respectively, meeting the criterion for SARA. However, animals with access to SG were less likely to advance to the next current than TMR animals (P<0.01) and were approximately 3x less willing to interact with higher currents than TMR (mean maximum current touched: 469±169 and 1380±254 mA, respectively, mean±SE, P=0.01). Lower motivation to access SG was further demonstrated through fewer visits to the SG (2.4±0.4 vs 5.3±0.6 #/d, P<0.01), and less SG consumed than TMR (32.0±0.1 vs 74.0±0.0 %/d, P<0.01). Overall, finishing cattle valued the TMR more than SG, likely because of differences in the quantity offered, palatability, and familiarity. When rumen health was considered, SG animals visited more often (r=0.5, P=0.09) and showed fewer failed attempts (r=-0.5, P=0.06) to access forage as the severity and duration of pH depression below 5.6, for example, increased. There was no relationship between any measure of treatment use and pH depression for TMR animals (P≥0.3). These findings provide evidence that cattle are motivated for Sudan grass hay when experiencing chronic low reticulorumen pH. However, the findings also contribute to the mixed evidence about motivation for forage in this life stage, because, overall TMR was valued more highly than SG. Indeed, despite widespread pH depression, TMR cattle contrafreeloaded for additional concentrate, demonstrating unexpectedly high motivation for this resource.

description: The paper surveys the expression of habitual meaning and the origins of habitual markers in four Bantu languages: Eton (A.71), Swahili (G.42), Fwe (K.402), and Nyanja/Chewa (N.31). The division of labour between the habitual marker and other tense and aspect markers differs between the languages, but the coexpression of habitual and generic meaning is found in three of them. Swahili and Fwe both testify to a development COP + INF > HAB, but otherwise the habitual markers under scrutiny have different origins. The final section of the paper considers my findings in light of the cross-linguistic literature on habituals.

description: We propose fully explicit projective integration and telescopic projective integration schemes for the multispecies Boltzmann and Bhatnagar-Gross-Krook (BGK) equations. The methods employ a sequence of small forward-Euler steps, intercalated with large extrapolation steps. The telescopic approach repeats said extrapolations as the basis for an even larger step. This hierarchy renders the computational complexity of the method essentially independent of the stiffness of the problem, which permits the efficient solution of equations in the hyperbolic scaling with very small Knudsen numbers. We validate the schemes on a range of scenarios, demonstrating its prowess in dealing with extreme mass ratios, fluid instabilities, and other complex phenomena.

description: We study the dynamics of a phantom scalar field dark energy interacting with dark matter in loop quantum cosmology (LQC). Two kinds of coupling of the form $α{ρ_m}{\dotϕ}$ (case I) and $3βH (ρ_ϕ+ρ_m)$ (case II) between the phantom energy and dark matter are examined with the potential for the phantom field taken to be exponential. For both kinds of interactions, we find that the future singularity appearing in the standard FRW cosmology can be avoided by loop quantum gravity effects. In case II, if the phantom field is initially rolling down the potential, the loop quantum effect has no influence on the cosmic late time evolution and the universe will accelerate forever with a constant energy ratio between the dark energy and dark matter.

Subjects: Curriculum Implementation, Knowledge Management, Teacher Education

description: The study investigated curriculum implementation and knowledge management in Nigerian teacher education process. The objective was to determine the extent of knowledge management in teacher education process in Nigeria. Two research questions were answered and one hypothesis tested. The study adopted descriptive survey design with a population of 226 lecturers in the Faculty of Education, Prince Abubakar Audu University, Anyigba, Kogi State and Rivers State University, Port Harcourt. A sample size of 80 lecturers was drawn using the proportionate stratified random sampling technique. The instrument for data collection was an 18- item questionnaire validated by three experts and it gave a reliability coefficient of 0.72 which was obtained using Cronbach Alpha method. The data collected was analyzed with mean and standard deviation and z-test for the hypothesis. The findings showed adequate management support for lecturers in North Central and inadequate management support for lecturers in the South-South and it was also revealed that there was poor provision of resources as perceived by male and female lecturers in teacher education process in Nigeria. It was then concluded that more work was required to boost management support for curriculum implementation in teacher education process, especially, in the South-South Nigeria

description: The ability to engineer nonlinear optical processes in all-dielectric nanostructures is both of fundamental interest and highly desirable for high-performance, robust, and miniaturized nonlinear optical devices. Herein, we propose a novel paradigm for the efficient tuning of second-harmonic generation (SHG) process in dielectric nanoantennas by integrating with chalcogenide phase change material. In a design with Ge$_{2}$Sb$_{2}$Te$_{5}$ (GST) film sandwiched between the AlGaAs nanoantennas and AlO$_{x}$ substrate, the nonlinear SHG signal from the AlGaAs nanoantennas can be boosted via the resonantly localized field induced by the optically-induced Mie-type resonances, and further modulated by exploiting the GST amorphous-to-crystalline phase change in a non-volatile, multi-level manner. The tuning strategy originates from the modulation of resonant conditions by changes in the refractive index of GST. With a thorough examination of tuning performances for different nanoantenna radii, a maximum modulation depth as high as 540$\%$ is numerically demonstrated. This work not only reveals out the potential of GST in optical nonlinearity control, but also provides promising strategy in smart designing tunable and reconfigurable nonlinear optical devices, e.g., light emitters, modulators, and sensors.

description: Deep learning models have been shown to be vulnerable to adversarial attacks. This perception led to analyzing deep learning models not only from the perspective of their performance measures but also their robustness to certain types of adversarial attacks. We take another step forward in relating the architectural structure of neural networks from a graph theoretic perspective to their robustness. We aim to investigate any existing correlations between graph theoretic properties and the robustness of Sparse Neural Networks. Our hypothesis is, that graph theoretic properties as a prior of neural network structures are related to their robustness. To answer to this hypothesis, we designed an empirical study with neural network models obtained through random graphs used as sparse structural priors for the networks. We additionally investigated the evaluation of a randomly pruned fully connected network as a point of reference. We found that robustness measures are independent of initialization methods but show weak correlations with graph properties: higher graph densities correlate with lower robustness, but higher average path lengths and average node eccentricities show negative correlations with robustness measures. We hope to motivate further empirical and analytical research to tightening an answer to our hypothesis.

description: Introduction: Cervical cancer is the third most prevalent cancer among women in Brunei Darussalam. This study aims to report the overall survival rates and associated factors of patients diagnosed with malignant cervical cancer in Brunei Darussalam. Methods: A retrospective study of patients diagnosed with cervical cancer from 2007 to 2017 in Brunei Darussalam. The data were obtained from the population-based cancer registry in Brunei Darussalam. Kaplan- Meier survival analysis was used to estimate the overall survival rates at 1-, 3- and 5-year intervals while the log-rank test was used to assess differences in survival between groups. Cox Proportional Hazard (PH) regression analysis was used to examine the association of demographic and clinical factors on the survival of cervical cancer patients. Results: A total of 329 registered malignant cervical cancer cases were analyzed. The mean age at diagnosis of patients with cervical cancer was 46.7 years. There were 28.6% deaths and the overall survival rates at 1, 3 and 5 years were 85.4%, 72.6% and 68.6% respectively. Age at diagnosis, cancer stage and histology types were significant predictive factors for overall survival of the patients diagnosed with cervical cancers when analysed on both log rank tests and Cox PH model. Conclusion: Age at diagnosis, cancer stage and histology types were significantly associated with the overall survival rates of cervical cancer patients in Brunei Darussalam. Early detection and management of cervical cancer at early stages should be prioritized to improve the survival rate and quality of cancer care.

We employ the presence of an additional vector type interaction and constrain the new physics coupling parameter using the existing experimental measurements on $R_K$ and $R_{K^*}$ observables. To understand the sensitivity of the new physics coupling, we investigate the impact of this coupling on various physical observables such as differential branching ratio, the forward-backward asymmetry, the lepton polarization asymmetry, the angular observable $P_5^{\prime}$, and the lepton universality parameters such as the ratio of the branching ratio $R_{f_2'(K_2^*)}$ and some important Q parameters of $B_{(s)} \to K_2^*(1430)(f_2'(1525)) \ell^+\ell^-$ processes at large recoil. We find some noticeable differences of the observables in the presence of light $Z^{\prime}$ contribution.

description: We derive an effective theory for dense, cold and massive quark matter. To this end, we employ a general effective action formalism where antiquarks and quarks far from the Fermi surface, as well as hard gluons, are integrated out explicitly. We show that the resulting effective action depends crucially on the projectors used to separate quarks from antiquarks. If one neglects the quark masses in these projectors, the Feynman rules of the effective theory involve quark mass insertions which connect quark with antiquark propagators. Including the quark masses into these projectors, mass insertions do not appear and the Feynman rules are identical to those found in the zero-mass limit.

The metadata are used to develop a large-scale imaging viewer that provides a straightforward graphical user interface to visualise a large microstructural tiling image at the gigabyte level. We applied the database to accumulate comprehensive microstructural imaging data produced by automated scanning electron microscopy. As a result, we have successfully managed vast numbers of images and their metadata, including the interpretation of morphological phenotypes occurring in sub-cellular components and biosamples captured in the images. We also discuss advanced utilisation of morphological imaging data that can be promoted by this database.

description: We construct the most general physically admissible positive-definite inner product on the space of Proca fields. Up to a trivial scaling this defines a five-parameter family of Lorentz invariant inner products that we use to construct a genuine Hilbert space for the quantum mechanics of Proca fields. If we identify the generator of time-translations with the Hamiltonian, we obtain a unitary quantum system that describes first-quantized Proca fields and does not involve the conventional restriction to the positive-frequency fields. We provide a rather comprehensive analysis of this system. In particular, we examine the conserved current density responsible for the conservation of the probabilities, explore the global gauge symmetry underlying the conservation of the probabilities, obtain a probability current density, construct position, momentum, helicity, spin, and angular momentum operators, and determine the localized Proca fields. We also compute the generalized parity ($\cP$), generalized time-reversal ($\cT$), and generalized charge or chirality ($\cC$) operators for this system and offer a physical interpretation for its $\cP\cT$-, $\cC$-, and $\cC\cP\cT$-symmetries.

description: Decomposition based approaches are recalled from primal and dual point of view. The possibility of building partially disaggregated reduced master problems is investigated. This extends the idea of aggregated-versus-disaggregated formulation to a gradual choice of alternative level of aggregation. Partial aggregation is applied to the linear multicommodity minimum cost flow problem. The possibility of having only partially aggregated bundles opens a wide range of  alternatives with different trade-offs between the number of iterations and the required computation for solving it. This trade-off is explored for several sets of instances and the results are compared with the ones obtained by directly solving the natural node-arc formulation.

An iterative solution process to the route assignment problem is proposed, based on the well-known Frank Wolfe algorithm. In order to provide a first feasible solution to the Frank Wolfe algorithm, a linear multicommodity min-cost flow problem is solved to optimality by using the  decomposition techniques mentioned above. Solutions of this problem are useful for network orientation and design, especially in relation with public transportation systems as the Personal Rapid Transit.

A single-commodity robust network design problem is addressed. In this, an undirected graph with edge costs is given together with a discrete set of balance matrices, representing different supply/demand scenarios. The goal is to determine the minimum cost installation of capacities on the edges such that the flow exchange is feasible for every scenario. A set of new instances that are computationally hard for the natural flow formulation are solved by means of a new heuristic algorithm.

Finally, an efficient decomposition-based heuristic approach for a large scale stochastic unit commitment problem is presented. The addressed real-world stochastic problem employs at its core a deterministic unit commitment planning model developed by the California Independent System Operator (ISO).

description: The Laser Interferometer Space Antenna, LISA, will detect gravitational wave signals from Extreme Mass Ratio Inspirals, where a stellar mass compact object orbits a supermassive black hole and eventually plunges into it. Here we report on LISA's capability to detect whether the smaller compact object in an Extreme Mass Ratio Inspiral is endowed with a scalar field, and to measure its scalar charge -- a dimensionless quantity that acts as a measure of how much scalar field the object carries. By direct comparison of signals, we show that LISA will be able to detect and measure the scalar charge with an accuracy of the order of percent, which is an unprecedented level of precision. This result is independent of the origin of the scalar field and of the structure and other properties of the small compact object, so it can be seen as a generic assessment of LISA's capabilities to detect new fundamental fields.

description: We propose a general method to cool the translational motion of molecules. Our method is an extension of single photon atomic cooling which was successfully implemented in our laboratory. Requiring a single event of absorption followed by a spontaneous emission, this method circumvents the need for a cycling transition and can be applied to any paramagnetic or polar molecule. In our approach, trapped molecules would be captured near their classical turning points in an optical dipole or RF-trap following an irreversible transition process.

description: A femtosecond laser pulse is able to switch the magnetic state of a 3d-4f ferrimagnetic material on a pico-second time scale. Devices based on this all-optical switching (AOS) mechanism are competitive candidates for ultrafast memory applications. However, a large portion of the light energy is lost by reflection from the metal thin film as well as transmission to the substrate. In this paper, we explore the use of dielectric coatings to increase the light absorption by the magnetic metal layer based on the principle of constructive interference. We experimentally show that the switching energy oscillates with the dielectric layer thickness following the light interference profile as obtained from theoretical calculations. Furthermore, the switching threshold fluence can be reduced by at least $80\%$ to 0.6 mJ/cm$^2$ using two dielectric SiO$_2$ layers sandwiching the metal stack, which scales to 15 fJ of incident energy for a cell size of $50^2$ nm$^2$.

description: We introduce and study a new topology on trees, that we call the countably coarse wedge topology. Such a topology is strictly finer than the coarse wedge topology and it turns every chain complete, rooted tree into a Fréchet--Urysohn, countably compact topological space. We show the rôle of such topology in the theory of weakly Corson and weakly Valdivia compacta. In particular, we give the first example of a compact space $T$ whose every closed subspace is weakly Valdivia, yet $T$ is not weakly Corson. This answers a question due to Ondřej Kalenda.

description: We present an alternative method for reconstructing a velocity-delay map in reverberation mapping (RM) based on the pixon algorithm initially proposed for image reconstruction by Pina & Puetter (1993). The pixon algorithm allows for a variable pixon basis to adjust resolution of each image pixel according the information content in that pixel, which therefore enables the algorithm to make the best possible use of measured data. The final optimal pixon basis functions would be those that minimize the number of pixons while still providing acceptable descriptions to data within the accuracy allowed by noises. We adapt the pixon algorithm to RM analysis and develop a generic framework to implement the algorithm. Simulation tests and comparisons with the widely used maximum entropy method demonstrate the feasibility and high performance of our pixon-based RM analysis. This paper serves as an introduction to the framework and the application to velocity-unresolved RM. An extension to velocity-resolved cases will be presented in a companion paper.

description: We introduce the strong CP-violation in the framework of AdS/QCD model and calculate the electric dipole moments of nucleons as well as the CP-violating pion-nucleon coupling. Our holographic estimate of the electric dipole moments gives for the neutron d_n=1.08 X 10^{-16} theta (e cm), which is comparable with previous estimates. We also predict that the electric dipole moment of the proton should be precisely the minus of the neutron electric dipole moment, thus leading to a new sum rule on the electric dipole moments of baryons.

description: We propose a phonon-assisted tunnelling model for explanation of conductivity dependence on temperature and temperature-dependent I-V characteristics in deoxyribonucleic acid (DNA) molecules. The capability of this model for explanation of conductivity peculiarities in DNA is illustrated by comparison of the temperature dependent I-V data extracted from some articles with tunnelling rate dependences on temperature and field strength computed according to the phonon-assisted tunnelling theory.

description: Expectedly, forty-nine years since the establishment of Economic Community of West African States (ECOWAS), there has been significant transformation in West African socioeconomic and political integration. Nonetheless, very recent developments in West Africa indicate a retreat in integration arrangements; most evidently, the resurgence of military rule in some member countries, followed by threats of withdrawal from ECOWAS. Invariably, there appears to be a mismatch between the level of institutional transformation and the extent of integration. As a matter of policy and multilateral exigency, Nigeria played a leading role in the formation of the Economic Community of West African States (ECOWAS) in 1975. In view of Nigeria’s dominant posture, and underlying challenges, a more concerted effort from Nigeria would guarantee a genuine integration of West Africa. This research therefore examines how Nigeria advanced the course of regional integration and the prospects thereof. Data from Primary and Secondary sources was analysed using the descriptive method. Dependency Theory was adopted to explain the enduring external strains on integration initiatives. Findings indicate that West African integration must correspond with transformation in democratic principles and practices, beginning with Nigeria, the dominant member, and extending to others.

Reactivity of the Si(100)-2$\times$1-Cl surface with respect to PH$_3$, PCl$_3$, and BCl$_3$: Comparison with PH$_3$ on Si(100)-2$\times$1-H

description: Despite the interest in a chlorine monolayer on Si(100) as an alternative to hydrogen resist for atomic-precision doping, little is known about its interaction with dopant-containing molecules. We used the density functional theory to evaluate whether a chlorine monolayer on Si(100) is suitable as a resist for \ce{PH3}, \ce{PCl3}, and \ce{BCl3} molecules. We calculated reaction pathways for \ce{PH3}, \ce{PCl3}, and \ce{BCl3} adsorption on a bare and Cl-terminated Si(100)-2$\times$1 surface, as well as for \ce{PH3} adsorption on H-terminated Si(100)-2$\times$1, which is widely used in current technologies for atomically precise doping of Si(100) with phosphorus. It was found that the Si(100)-2$\times$1-Cl surface has a higher reactivity towards phosphine than Si(100)-2$\times$1-H, and, therefore, unpatterned areas are less protected from undesirable incorporation of \ce{PH3} fragments. On the contrary, the resistance of the Si(100)-2$\times$1-Cl surface against the chlorine-containing molecules turned out to be very high. Several factors influencing reactivity are discussed. The results reveal that phosphorus and boron trichlorides are well-suited for doping a patterned Cl-resist by donors and acceptors, respectively.
Detection of a Rare Supersoft Outburst Event during a Suzaku Observation of 1E0102.2-7219

description: We report the detection of a transient X-ray source toward the Small Magellanic Cloud (SMC) using the X-ray Imaging Spectrometer (XIS) onboard the Suzaku telescope. The source was detected at the edge of the XIS image during a routine observation of the calibration source 1E 0102.2-7219, a supernova remnant in the SMC. We constrained the source position using ray-tracing simulations. No such transient source was found at the position in the other Suzaku observations nor in all the available archived images of other X-ray missions for the last ~28 years. The XIS spectrum can be explained by a single blackbody with a temperature of ~72 eV, and an interstellar extinction of ~4.9x10^{20} H atoms cm^{-2} consistent with the value to the SMC. An additional absorption edge at ~0.74 keV was also confirmed, which is presumably due to the absorption by helium-like oxygen ions. Assuming that the source is at the distance of the SMC, the X-ray luminosity in the 0.2-2.0 keV band is ~10^{37} erg s^{-1} and the radius of the source is ~10^{8} cm. The XIS light curve shows about a two-fold decline in X-ray flux during the 24 ks observation. Together with the archived data, the X-ray flux in the burst is at least three orders of magnitude brighter than the undetected quiescent level. All these properties are often seen among supersoft sources (SSSs). We conclude that the transient source is another example of SSS in the SMC.

Evolutionary Prisoner's Dilemma game on the Newman-Watts networks

description: Maintenance of cooperation was studied for a two-strategy evolutionary Prisoner's Dilemma game where the players are located on a one-dimensional chain and their payoff comes from games with the nearest and next-nearest neighbor interactions. The applied host geometry makes possible to study the impacts of two conflicting topological features. The evolutionary rule involves some noise affecting the strategy adoptions between the interacting players. Using Monte Carlo simulations and the extended versions of dynamical mean-field theory we determined the phase diagram as a function of noise level and a payoff parameter. The peculiar feature of the diagram is changed significantly when the connectivity structure is extended by extra links as suggested by Newman and Watts.

description: We present an extensive introduction to quantum collision models (CMs), also known as repeated interactions schemes: a class of microscopic system-bath models for investigating open quantum systems dynamics whose use is currently spreading in a number of research areas. Through dedicated sections and a pedagogical approach, we discuss the CMs definition and general properties, their use for the derivation of master equations, their connection with quantum trajectories, their application in non-equilibrium quantum thermodynamics, their non-Markovian generalizations, their emergence from conventional system-bath microscopic models and link to the input-output formalism. The state of the art of each involved research area is reviewed through dedicated sections. The article is supported by several complementary appendices, which review standard concepts/tools of open quantum systems used in the main text with the goal of making the material accessible even to readers possessing only a basic background in quantum mechanics. The paper could also be seen itself as a friendly, physically intuitive, introduction to fundamentals of open quantum systems theory since most main concepts of this are treated such as quantum maps, Lindblad master equation, steady states, POVMs, quantum trajectories and stochastic Schrodinger equation.

description: Part of a collection of correspondence from Kathleen Raine to Robin Skelton. Skelton was a British poet, academic, anthologist, and practicing Wiccan. He taught at Manchester University before emigrating to Canada in 1963, where he taught creative writing at the University of Victoria and started the literary magazine The Malahat Review. Also included are some letters to Skelton’s wife Sylvia, and his daughters. Spanning close to forty-five years, the correspondence discusses poetry, writing, and philosophy; particularly Platonism and Neoplatonism. Raine often refers to the writings of William Blake and W. B. Yeats. Many letters also mention contemporary literary figures at the time including: Herbert Read, Peter Russell, Liam Miller, and Thurairajah Tambimuttu. This letter includes a Christmas card to Robin and Sylvia Skelton. In this letter, Raine relates conflict between Liam Miller, Hamish Hamilton, and Thurairajah Tambimuttu for publishing her most revent book.
