Dietary fenugreek seed extract improves dry matter intake, apparent total tract nutrient digestibility, and alters whole blood transcriptome of Holstein dairy heifers

Abstract This study was conducted to evaluate the effects of dietary supplementation of a fenugreek seed extract (SAP) as a source of saponins on dry matter intake, blood metabolites, apparent total tract nutrient digestibility, and whole blood transcriptome of Holstein dairy heifers. Eight heifers (BW = 477 ± 23.8 kg) were stratified by BW and then randomly assigned to one of two treatments in a cross-over design with two 35-d experimental periods and a 14-d wash-out between the two periods. The heifers were housed individually in eight dry lot pens. Each pen was equipped with one GrowSafe intake node. Treatments were 1) corn silage-based diet with no additive (CON) and 2) corn silage-based diet plus 2 g per hd per d of SAP. Dairy heifers fed supplemental SAP had higher (P ≤ 0.05) DMI and apparent total tract digestibility of dry matter, crude protein, and neutral detergent fiber compared to CON. Dairy heifers fed supplemental SAP had lower (P = 0.03) blood urea nitrogen and higher (P = 0.01) blood glucose concentration compared to CON. Pathway analysis via gene set enrichment analysis revealed increased (FDR ≤ 0.05) transcript levels for gene sets belonging to ISG15 antiviral mechanism, metabolism of proteins, citric acid cycle and respiratory electron transport, ATP synthesis by chemiosmotic coupling, and complex I biogenesis in dairy heifers fed supplemental SAP compared to CON. Decreased (FDR ≤ 0.05) transcript levels for gene sets associated with erythrocytes take up/release carbon dioxide, release/take up oxygen, and O2/CO2 exchange in erythrocytes were also observed with SAP supplemental group. Taken together, our results revealed that fenugreek seed extract can be used as an effective dietary supplement for dairy heifers to improve intake and digestibility, and alter the host transcriptome toward improved energy and amino acid metabolism, improved antiviral immune status, and reduced oxidative stress damage.
A neutrino mixing model based on an $A_4\times Z_3\times Z_4$ flavour symmetry

A model of a neutrino mixing with an $A_4\times Z_3\times Z_4$ flavour symmetry is suggested. In addition to the standard model fields, the present model contains six new fields which transform under different representations of $A_4\times Z_3\times Z_4$. The model is constructed to slightly deviate from a tri-bi-maximal model in agreement with the current experimental data, thus, all analysis can be done in the base of the perturbation method. Within this model, as an application, a relation between the mixing angles ($\theta_{12}, \theta_{23}, \theta_{13}$) and the Dirac CP-violation phase ($\delta_{CP}$) is established. This relation allows a prediction of $\delta_{CP}$ and the Jarlskog parameter ($J_{CP}$). The predicted value $\delta_{CP}$ is in the 1$\sigma$ region of the global fit for both the normal- and inverse neutrino mass ordering and gives $J_{CP}$ to be within the bound $|J_{CP}|\leq 0.04$. For an illustration, the model is checked numerically and gives values of the neutrino masses (of the order of 0.1 eV) and the mixing angle $\theta_{13}$ (about $9^\circ$) very close to the current experimental data.
Technological Pedagogical and Content Knowledge (TPACK): Analysis in Design Selection and Data Analysis Techniques in High School

The learning process that is integrated with technology requires teachers who are able to integrate professional skills, pedagogical abilities, and technology in learning. This study uses a content analysis of a number of SCOPUS indexed articles that have been published throughout 2020 with the main focus of the study being TPaCK. This study aims to inform the diversity of research types, research designs, subjects, subjects, data collection instruments and data analysis techniques. The results revealed that the most dominant types of research were quantitative and R&D. In addition, research design methods that are becoming a trend are R&D and survey research. Popular research subjects and subject matter are students with a subject or major in Science and Physics. The most commonly used instruments are questionnaires and tests. Meanwhile, the most widely used data analysis techniques are percentage, n-gain, paired sample t-test and descriptive analysis. In addition, it was also found that several researchers used the same research design but different instruments and data collection. Based on the results of this study, several recommendations have been proposed for future researchers that support TPaCK as the main focus. Some of these recommendations include increasing the diversity of types of research and choosing the right method in conducting research.
High-Performance Image Synthesis for Radio Interferometry

A radio interferometer indirectly measures the intensity distribution of the sky over the celestial sphere. Since measurements are made over an irregularly sampled Fourier plane, synthesising an intensity image from interferometric measurements requires substantial processing. Furthermore there are distortions that have to be corrected. In this thesis, a new high-performance image synthesis tool (imaging tool) for radio interferometry is developed. Implemented in C++ and CUDA, the imaging tool achieves unprecedented performance by means of Graphics Processing Units (GPUs). The imaging tool is divided into several components, and the back-end handling numerical calculations is generalised in a new framework. A new feature termed compression arbitrarily increases the performance of an already highly efficient GPU-based implementation of the w-projection algorithm. Compression takes advantage of the behaviour of oversampled convolution functions and the baseline trajectories. A CPU-based component prepares data for the GPU which is multi-threaded to ensure maximum use of modern multi-core CPUs. Best performance can only be achieved if all hardware components in a system do work in parallel. The imaging tool is designed such that disk I/O and work on CPU and GPUs is done concurrently. Test cases show that the imaging tool performs nearly 100$\times$ faster than another general CPU-based imaging tool. Unfortunately, the tool is limited in use since deconvolution and A-projection are not yet supported. It is also limited by GPU memory. Future work will implement deconvolution and A-projection, whilst finding ways of overcoming the memory limitation.
Role of charged defects on the electrical and electromechanical properties of rhombohedral Pb(Zr,Ti)O3 with oxygen octahedra tilts

Oxygen octahedra tilting is a common structural phenomenon in perovskites and has been subject of intensive studies, particularly in rhombohedral Pb(Zr,Ti)O3 (PZT). Early reports suggest that the tilted octahedra may strongly affect the domain switching behavior as well as the dielectric and piezoelectric properties of PZT ceramics. In a way similar to that proposed for tilts, however, charged defects, associated with oxygen vacancies, may also inhibit the motion of the domain walls, resulting macroscopically in pinched hysteresis loops and reduced piezoelectric response. Here, we revisit the early studies on rhombohedral PZT ceramics with tilted octahedra by considering a possible role of both tilts and charged defects on domain-wall motion. We show that the observed pinched hysteresis loops are likely associated with the presence of defect complexes containing charged oxygen vacancies, and not tilts, as suggested in some cases. Regardless of the presence or absence of long-range ordered tilts in rhombohedral PZT, the effect of charged defects is also prominent in weak-field permittivity and piezoelectric properties, particularly at sub-Hertz driving conditions where the conductivity, related to the motion of oxygen vacancies, gives rise to strong frequency dispersion.
Faraday rotation and L band oceanographic measurements

Spaceborne radiometric measurements of the L band brightness temperature over the oceans make it possible to estimate sea surface salinity. However, Faraday rotation in the ionosphere disturbs the signals and must be corrected. Two different ways of assessing the disturbance directly from the radiometric measurements, and hence enabling a correction for the effect, are being discussed. Also, a method, which aims at circumventing the problem by using the first Stokes parameter in the salinity retrieval, is being discussed.
On the gluing problem for the $\eta$-invariant

We solve the gluing problem for the ^-invariant. Consider a generalized Dirac operator D over a compact Riemannian manifold M that is partitioned by a compact hypersurface N such that M :- Mχ UN M2 . We assume that the Riemannian metric of M and D have a product structure near N, i.e., D = I{d/dτ + DN) with some Dirac operator DN on N. Using boundary conditions of Atiyah-Patodi -Singer type parametrized by Lagrangian subspaces L, of kerD^ we define selfadjoint extensions D /, i = 1,2, over M{. We express the //-invariant of D in terms of the //-invariants of Di, an invariant m(Lι, L2) of the pair of the Lagrangian subspaces Lχ, L2 , which is related to the Maslov index and an integer-valued term J . In the adiabatic limit, i.e., if a tubular neighborhood of N is long enough, the vanishing of J is shown under certain regularity conditions. We apply this result in order to prove cutting and pasting formulas for the ^/-invariant, a Wall nonadditivity result for the index of Atiyah-Patodi -Singer boundary value problems and a splitting formula for the spectral flow. 1. The gluing problem and applications 1.1. Introduction. We solve the gluing problem for the ^/-invariant of generalized Dirac operators. Consider a closed, compact Riemannian manifold carrying a Dirac bundle with a generalized Dirac operator. Assume that this manifold is separated into two pieces by a compact hypersurface. The gluing problem for the ^/-invariant consists in expressing the ^/-invariant of the original Dirac operator in terms of the ^/-invariants of the Dirac operators living on the pieces. The selfadjoint operators on the two components with boundary depend on a boundary condition given by Lagrangian subspaces Lx, L2 of a certain symplectic vector space. The gluing formula also contains an additional real-valued term m(L{, L2), which is nicely related to the symplectic geometry and the Maslov index.

Applications des immeubles en théorie des représentations

This is a survey about the connection between the representation theory of a semisimple group and the geometry of an affine building. The latter is, actually, associated to the Langlands'dual of the semisimple group. We deal, mainly, with the proof of the saturation theorem of Kapovich and Millson. We obtain a simplification of their proof regarding the characterization of folded triangles. The article is written in french for it is the outcome of a seminar that took place in Nancy last year.
RESEARCH ON EXTREMELY LOW FREQUENCY PROPAGATION WITH PARTICULAR EMPHASIS ON SCHUMANN RESONANCE AND RELATED PHENOMENA.

Abstract : Propagation characteristics of ELF waves in interplanetary space between the sun and the bow-shock of the magnetosphere are considered for parallel propagation. It is shown that only the right hand circularly polarized transverse wave and the longitudinal ion acoustic wave can propagate during normal quiescent conditions. However, damping is sufficiently high to make it unlikely that waves will be detected in the vicinity of the earth at any appreciable distance. For perpendicular propagation both 'ordinary' and 'extraordinary' modes are considered. (Author)
Electronic properties of armchair AA-stacked bilayer graphene nanoribbons

We study analytically, based on the tight-binding model, the electronic band structure of armchair AA-stacked bilayer graphene nanoribbons (BLGNRs) in several regimes. We apply hard-wall boundary conditions to determine the discretion dominating on the Bloch wavefunctions in the confined direction. First we consider an ideal case, perfect nanoribbons without any edge deformation, and show that their electronic properties are strongly size-dependent. We find that the narrow armchair AA-stacked BLGNRs (similar to single-layer graphene nanoribbons) may be metallic or semiconducting depending on their width determined by the number of dimer lines across the ribbon width, while the wide ribbons are metallic. Then we show that, when the edge deformation effects are taken into account, all narrow armchair AA-stacked BLGNRs become semiconducting while the wide ribbons remain metallic. We also investigate effects of an electric filed applied perpendicular to the nanoribbon layers and show it can be used to tune the electronic properties of these nanoribbons leading to a semiconducting-to-metallic phase transition at a critical value of the electric field which depends on the nanoribbon width. Furthermore, in all regimes, we calculate the corresponding wavefunctions which can be used to investigate and predict various properties in these nanoribbons.
Institute for Molecular Physics at the University of Maryland

The Institute for Physical Science and Technology at the University of Maryland was founded in 1976 from a merger of the Institute for Fluid Dynamics and Applied Mathematics (IFDAM) and the Institute for Molecular Physics (IMP), which were established at the College Park Campus after World War II to enhance the expertise of the University of Maryland in some areas of science and technology of interest to the US Department of Defense. Here I try to reconstruct the history of the Institute for Molecular Physics at the University of Maryland.
HOW DO NUMERICAL METHODS EFFECT STATISTICAL DETAILS OF RICHTMYER-MESHKOV INSTABILITIES

Over the past several years we have presented a less than glowing experimental comparison of hydrodynamic codes with the gas curtain experiment. Here, we discuss the manner in which the various details of the hydrodynamic integration techniques conspire to produce poor results. This also includes some progress in improving the results and agreement with experimental results. Our results are based upon the gas curtain, Richtmyer-Meshkov experiments conducted by Rightley et al. (Rightley et al. 1999) at Los Alamos. We also examine the results of a gas cylinder experiment conducted more recently by Prestridge and Zoldi which includes velocity data obtained via a PIV technique. Traditionally, the integral width of the mixing layer is used as a yardstick to measure the Richtmyer-Meshkov instability. This is also used when investigating the performance of numerical methods. Our focus has been on the details of the mixing below the integral scale. Because the flow is hydrodynamically unstable, we employ statistical measures in our comparisons. This is built upon a parallel effort by the experimentalists investigating the statistical nature of the mixing induced by shock waves. The principle tools we use to measure the spectral structure of the images of these flows are the fractal dimension and the continuous wavelet spectrum. The bottom line is that all the higher order methods used to simulate the gas curtain compare poorly with the experimental data when quantified with these spatial statistics. Moreover, the comparisons degrade under mesh refinement. This occurs despite the fact that the integral scale comparison is acceptable and consistent with the expectations from this class of methods. The most surprising result is that a first-order Godunov method does produce a good comparison relative to the assumed to be higher-order methods. We have examined a broad variety of methodologies associated with the high-order methods to illuminate this problematic result. In the next section we briefly describe the experiments. In Section the quantitative measures applied to the images are detailed; the results of these analyses are discussed in Section refsec:compare. The consideration of the relation between turbulence models and numerical methods was inspired by these results and is discussed.
Experimental study on the effect of simulated grass and stem coverage on resistance coefficient of overland flow

Vegetation plays a significant role in preventing desertification, conservation of soil and water. However, nowadays, there is still uncertainty regarding the mechanisms of flow resistance caused by dissimilar vegetation covers. To address this gap, a series of these was conducted in this study to investigate the influence of synthetic grass and stems on the variation of resistance on overland flows. Thirty vegetation configurations were selected (combining five synthetic grass coverage options and six synthetic stem coverage ones), and tested against five unit discharges (flow range = 0.28–2.22 L m−1 s−1) and four slope gradients (3.49%–20.78%). The results obtained showed that the unit discharge is the key driving factor for the transition from laminar to transitional flow. Furthermore, the relationship between the resistance coefficient (f) and the Reynolds number (Re) was not monotonically increasing or decreasing, but behaviours observed were specifically linked to each vegetation coverage. However, a critical coverage threshold was identified, and it corresponded to 2.72% when the slope gradient tested was 3.49%. This threshold decreased with the increase of the slope gradient. In addition, when the vegetation coverage was less than the critical threshold, the f was negatively correlated with Re, otherwise if the vegetation coverage was higher than the critical threshold identified the f–Re relation was positively correlated. The total flow resistance under synthetic grass and stem cover was unequal to the linear superposition of grain resistance and form resistance caused by synthetic stem and grass, which meant that the linear superposition approach is not applicable to overland flows. Finally, a model was developed to predict the flow resistance by applying the π‐theorem and the multiple nonlinear regression analysis and it has been validated against the experimental results confirming its accuracy and high performance (adj.R2 = 0.99, NSE = 0.94).
Asymptotic near-efficiency of a "Gibbs-energy" estimating function approach for fitting Matern covariance models to a dense (noisy) series

Let us call “Gibbs energy” the quadratic form occurring in the maximum likelihood (ML) criterion when ﬁtting a zero-mean multidimensional Gaussian distribution to one realization. We consider a continuous-time Gaussian process Z which belongs to the Matern family with known regularity index $\nu$ ≥ 1/2. For estimating the range and the variance of Z from noisy observations on a dense regular grid, we propose two simple estimating functions based on the conditional Gibbs energy mean (CGEM) and the empirical variance (EV). We show that the ratio of the large sample mean square error of the CGEM-EV estimate of the range-parameter over the one of its ML estimate, and the analog ratio for the variance-parameter, both converge (when the grid-step tends to 0) toward a constant, only function of $\nu$, surprisingly close to 1 provided $\nu$ is not too large. Extensions of this approach, which may enjoy a very easy numerical implementation, are brieﬂy discussed.
Anti-de Sitter black holes in supergravity

Anti-de Sitter Black Holes in Supergravity. (August 2006) Zhiwei Chong, B.S., Fudan University, Shanghai, China Chair of Advisory Committee: Dr. Christopher Pope In this dissertation, we systematically construct non-extremal charged rotating anti-de Sitter black hole solutions in four, five and seven dimensions. In four dimensions, we first obtain the rotating Kerr-Taub-NUT metric with four independent charges, as solutions of N = 2 supergravity coupled to three abelian vector multiplets by the solution generating technique. Then we generalise the four-dimensional rotating solutions to the solutions of gauged N = 4 supergravity with charges set pairwise equal. In five dimensions, the most general charged rotating black hole solution has three charge and two rotation parameters. We obtain several special cases of the general solution. To be specific, we obtain the first example of a non-extremal rotating black hole solution with two independent rotation parameters, which has two charge parameters set equal and the third vanishing. In another example, we obtain the nonextremal charged rotating black hole solution with three charge parameters set equal and non-equal rotation parameters. We are also able to construct the single-charge solution with two independent rotation parameters. In seven dimensions, we obtain the solution for non-extremal charged rotating black holes in gauged supergravity, in the case where the three rotation parameters are set equal. There are two independent charges, corresponding to gauge fields in the U(1) × U(1) abelian subgroup of the SO(5) gauge group.

Measurement of the Target-Normal Single-Spin Asymmetry Any in the Deep Inelastic Region from the Reaction 3H e↑(e,e')

A first measurement of the inclusive target single-spin asymmetry, Any, has been performed in deep-inelastic scattering of electrons from a 3He target polarized normal to the electron scattering plane. This asymmetry is void of contributions at the Born level, and thus is a direct observable for two-photon physics. The experiment was performed in Hall A at Thomas Jefferson National Accelerator Facility from October 2008 through early February 2009. The measurement is the first from a polarized neutron target. The final overall precision is several times better than previously existing SLAC proton data, and significantly extends the kinematic range over which the asymmetry has been measured. The asymmetry was measured at five kinematic points in the deep inelastic scattering region covering Q2 = 1 - 3 GeV2 and xB = 0.16 to 0.41. The asymmetry varied from 0.006 to 0.071 with astatistical precision at the 10-2 level.
