description: Разработан и испытан рецепт комбикорма для телят, в котором использована техническая масляная культура – рыжик посевной. В его состав также было включено зерно ячменя, пшеницы, овса, кукурузы, минеральный источник кальция и фосфора, соль поваренная. Все растительные компоненты предварительно были обработаны путем экструзии. Экспериментальное скармливание проведено на фоне контрольной группы телят-аналогов, у которых в рационе использовался комбикорм, составленный из традиционных компонентов. Скармливание животным экструдата семян рыжика в составе рациона в течение 2-х месяцев способствовало большему потреблению кормов – сена и сенажа в среднем на 4,6 %, комбикорма – на 4,4 %. Валовой прирост живой массы телят опытной группы за период эксперимента был больше на 3,3 кг, а среднесуточный прирост – на 45 г, что составляет 7,3% (p ≤ 0,01) по отношению к соответствующим показателям животных контрольной группы.
description: A recipe for compound feed for calves has been developed and tested, in which a technical oil culture – a seed ginger is used. It also included grains of barley, wheat, oats, corn, a mineral source of calcium and phosphorus, and table salt. All plant components were previously processed by extrusion. Experimental feeding was carried out against the background of a control group of analog calves, whose diet used compound feed made up of traditional components. Feeding ginger seed extrudate to animals as part of the diet for 2 months contributed to a greater consumption of feed – hay and haylage by an average of 4.6%, compound feed – by 4.4%. The gross increase in live weight of calves of the experimental group during the experiment period was 3.3 kg more, and the average daily increase was 45 g, which is 7.3% (p ≤ 0.01) relative to the corresponding indicators of animals of the control group.

Role of connexin 43 in regulating wound healing-related gene expression in human skin and gingival fibroblasts
Creators: name: Tarzemany, Rana
Publisher: name: University of British Columbia
Year: 2018

description: Wound healing in human oral mucosal gingiva is faster and results in significantly reduced scar formation as compared to similar skin wounds. Fibroblasts are the most abundant group of connective tissue cells that play a key role in wound healing and scar formation. It is possible that differential healing outcomes in skin and gingiva may relate to the distinct phenotypic features of fibroblasts residing in these tissues. In fibroblasts, cells-to-cell communication occurs partly through connexin (Cx) hemichannels (HCs) and gap junctions (GJs). Findings from previous studies have shown that functional blockage of connexin 43 (Cx43), the most ubiquitous Cx in skin (SFBLs) and gingival fibroblasts (GFBLs), accelerates wound closure in skin and may alleviate scarring, but the mechanisms are poorly understood and may involve modulation of Cx43 function in fibroblasts. In the present dissertation, we show that (1) Cx43 was the most abundant Cx present in cultured human SFBLs and GFBLs. (2) Its abundance was potently downregulated at the early stage of human gingival wound healing. (3) Cx43 assembled into GJ and HC plaques in skin and gingival epithelium and connective tissue fibroblasts, although its distribution into GJs or HCs was markedly different in these two tissues. (4) Cx43 mainly assembled into HCs in GFBLs while in SFBLs only a few HCs were present in vivo and in vitro. (5) Using an in vivo-like 3D culture model and Cx43 mimetic peptides to block its function, we showed that the GJ, HC, and channel-independent functions of Cx43 distinctly upregulate anti-fibrotic and downregulate profibrotic wound healing-related genes in GFBLs and SFBLs. (6) In GFBLs this response was mainly mediated by activation of ERK1/2 pathway via Cx43 HC blockage. Thus, Cx43 assembly into GJs and HCs and its function are distinct in SFBLs and GFBLs, which may contribute to the different wound healing outcomes in these tissues. Furthermore, specific blockage of Cx43 HC functions may provide a novel target to promote wound healing and alleviate scar formation.

description: We report the status of nucleon structure calculations on the (2+1)-flavor dynamical domain-wall fermions ensembles with pion masses as low as 180 and 250 MeV on a lattice with about 4.6 fm spatial extent. A combination of the Iwasaki+dislocation- suppressing-determinant-ratio (I+DSDR) gauge action and DWF fermion action allows us to generate these ensembles at cutoff of about 1.4 GeV while keeping the residual mass small. Nucleon source Gaussian smearing has been optimized. Preliminary nucleon mass estimates are 0.98 and 1.05 GeV.

Radio Remnants of Compact Binary Mergers - the Electromagnetic Signal that will follow the Gravitational Waves

description: The question "what is the observable electromagnetic (EM) signature of a compact binary merger?" is an intriguing one with crucial consequences to the quest for gravitational waves (GW). Compact binary mergers are prime sources of GW, targeted by current and next generation detectors. Numerical simulations have demonstrated that these mergers eject energetic sub-relativistic (or even relativistic) outflows. This is certainly the case if the mergers produce short GRBs, but even if not, significant outflows are expected. The interaction of such outflows with the surround matter inevitably leads to a long lasting radio signal. We calculate the expected signal from these outflows (our calculations are also applicable to short GRB orphan afterglows) and we discuss their detectability. We show that the optimal search for such signal should, conveniently, take place around 1.4 GHz. Realistic estimates of the outflow parameters yield signals of a few hundred $μ$Jy, lasting a few weeks, from sources at the detection horizon of advanced GW detectors. Followup radio observations, triggered by GW detection, could reveal the radio remnant even under unfavorable conditions. Upcoming all sky surveys can detect a few dozen, and possibly even thousands, merger remnants at any give time, thereby providing robust merger rate estimates even before the advanced GW detectors become operational. In fact, the radio transient RT 19870422 fits well the overall properties predicted by our model and we suggest that its most probable origin is a compact binary merger radio remnant.

description: Food systems have a great potential to fulfill food security and nutrition for providing year-round healthy and affordable diets for all. Currently, however, our food systems have not yet delivered their full potential, leaving billions of people food insecure and unable to afford healthy diets; millions of children are stunted and wasted; and there is rising prevalence of obesity and non-communicable diseases. Hence, food systems in many parts of the world fail to deliver their missions! In the Asia-Pacific, the situation is exacerbated by population growth, urbanisation, changing consumption patterns, COVID-19, and the Ukraine war, and it is further complicated by climate change leading to unhealthy diets, poor nutrition and health, as well as unsustainable livelihoods and environment. Climate affects agri-food production which, however, is also a contributor to climate change. One-third of GHG emissions are generated from food systems. Climate change influences the entire food systems: poor soil fertility and reduced crop yield, biodiversity loss, pest diseases, reduced density and bioavailability of nutrients in foods, etc. Thus, climate change may increase malnutrition and health risks, deteriorate livelihoods and unsustainable environment. Sustainable and resilient food systems transformation coupled with nature-positive solutions, including climate-smart agriculture aligned with contextual ecosystem function, biodiversity and environmental conservation are warranted to ensure healthier diets and optimal health, and to mitigate and adapt the impact of climatic and food system interactions on diet, health and environment. Food systems transformation can harness the power of food systems to benefit humanity and the earth.

description: We have used the molecular beam growth technique, which we call cleaved edge overgrowth, to fabricate highly efficient lasers that operate in the 1D quantum limit. The active region of our laser consists of atomically precise quantum wires that form at the T-shaped intersections of 7 nm wide GaAs quantum wells grown along the (001) and, after an in situ cleave, along the (110) crystal axis. The origin of the quantum mechanical bound state is the relaxation of quantum well confinement at this intersection, which leads to an expansion of the electron and hole wavefunction into the larger available volume at the T-junction. The high degree of structural perfection achievable in this way allows the observation of stimulated optical emission from the lowest exciton state in optically pumped devices. The interpretation that the observed quantum wire response is due to exciton recombination is based on the near spectral constancy of the emission over almost three orders of magnitude in excitation power from low-power luminescence to a single-mode lasing line. The implied absence of bandgap renormalization effects suggests that the Mott density is never reached and indicates interesting new behaviour of excitons in 1D. In contrast, the quantum well photoluminescence peak indeed shifts to lower energies consistent with the notion that the 2D excitons ionize and a free electron-hole plasma forms.
Equivalence of domains for hyperbolic Hubbard-Stratonovich transformations

description: We settle a long standing issue concerning the traditional derivation of non-compact non-linear sigma models in the theory of disordered electron systems: the hyperbolic Hubbard-Stratonovich (HS) transformation of Pruisken-Schaefer type. Only recently the validity of such transformations was proved in the case of U(p,q) (non-compact unitary) and O(p,q) (non-compact orthogonal) symmetry. In this article we give a proof for general non-compact symmetry groups. Moreover we show that the Pruisken-Schaefer type transformations are related to other variants of the HS transformation by deformation of the domain of integration. In particular we clarify the origin of surprising sign factors which were recently discovered in the case of orthogonal symmetry.

description: We discuss a three-dimensional (3D) spin drift diffusion (SDD) model to inject spin from a ferromagnet (FM) to a normal metal (N) or semiconductor (SC). Using this model we investigate the problem of spin injection into isotropic materials like GaAs and study the effect of FM contact area and SC thickness on spin injection. We find that in order to achieve detectable spin injection a small contact area or thick SC samples are essential for direct contact spin injection devices. We investigate the use of thin metal films (Cu) proposed by S.B. Kumar et al. and show that they are an excellent substitute for tunnelling barriers (TB) in the regime of small contact area. Since most tunnelling barriers are prone to pinhole defects, we study the effect of pinholes in AlO tunnelling barriers and show that the reduction in the spin-injection ratio ($γ$) is solely due to the effective area of the pinholes and there is no correlation between the number of pinholes and the spin injection ratio.

description: We report on a novel contact scheme which for the first time makes possible magnetotransport measurements on individual quasi-1D quantum wires prepared by cleaved edge overgrowth. Contacting is achieved via two isolated 2D electron systems that are connected to one another by the quantum wire under study. Two-terminal magnetoresistance measurements along our modulation-doped quantum wires exhibit electron mobilities in excess of 2 × 105 cm2/Vs and show pronounced Shubnikov-de Haas oscillations. Clear evidence for confinement of the electrons in 2D is deduced from the retarded depopulation of Landau levels at low magnetic fields. The results are in close agreement with a calculation of the magnetic field dependence of the number of occupied subbands in a narrow channel.

description: We demonstrate that so called "infrared divergences" which have been discussed in some publications during several years, do not appear within the correct treatment of analytical properties of the transition amplitudes, in particular, of the second order pole structure of the amplitudes describing the $n - \bar n$ transition in nuclei. Explicit calculation with the help of the Feynman diagram technique shows that the neutron-antineutron oscillations are strongly suppressed in the deuteron, as well as in heavier nuclei, in comparison with the oscillations in vacuum. General advantages and some difficulties of the field theoretical methods applied in nuclear theory are reminded for the particular example of the parity violating $np\to dγ$ capture amplitude.

description: Microalgae of the family Chlorellaceae are of special interest to the food, feed, and nutraceutical industry, due to their high content of valuable nutrients. However, the bioaccessibility is limited by the rigid and polymorph cell wall of these species. This work aimed to characterize the cell walls of three Chlorellaceae strains in-vivo and in-vitro under industry-related culturing conditions. Histochemical staining and detailed analyses of cell wall monosaccharide composition identified changes in the composition during cell maturation in Chlorella sorokiniana SAG 211-8k, Chlorella vulgaris SAG 211-11b and Parachlorella kessleri SAG 211-11g. The cell walls of C. sorokiniana and P. kessleri developed a higher hemicellulose content (defined as susceptible to 2 mol/L trifluoroacetic acid hydrolysis) with stable amounts of the recalcitrance components (susceptible to 6 mol/L HCl). In contrast, the cell wall of C. vulgaris incorporated increasingly recalcitrance components and developed higher robustness.Additionally, a novel endogenous cell-wall-lytic enzyme (autologous Autolysin) was extracted from C. sorokiniana and P. kessleri. It showed endo-β-1,3-Glucanase activity, and partial autologous cell wall degradation in both strains. Thus, presenting a first step towards more effective methods for increased bioaccessibility, protoplast formation and genetic manipulation of Chlorellaceae strains.

description: We present here an extensive theoretical analysis of the supercurrent of a superconducting point contact of arbitrary transparency in the presence of a microwave field. Our study is mainly based on two different approaches: a two-level model that describes the dynamics of the Andreev bound states in these systems and a fully microscopic method based on the Keldysh-Green function technique. This combination provides both a deep insight into the physics of irradiated Josephson junctions and quantitative predictions for arbitrary range of parameters. The main predictions of our analysis are: (i) for weak fields and low temperatures, the microwaves can induce transitions between the Andreev states leading to a large suppression of the supercurrent at certain values of the phase, (ii) at strong fields, the current-phase relation is strongly distorted and the corresponding critical current does not follow a simple Bessel-function-like behavior, and (iii) at finite temperature, the microwave field can enhance the critical current by means of transitions connecting the continuum of states outside the gap region and the Andreev states inside the gap. Our study is of relevance for a large variety of superconducting weak links as well as for the proposals of using the Andreev bound states of a point contact for quantum computing applications.

description: This paper presents a straightforward application of an indirect method based on a three-microphone impedance tube setup to determine the non-acoustic properties of a sound absorbing porous material. First, a three-microphone impedance tube technique is used to measure some acoustic properties of the material (i.e., sound absorption coefficient, sound transmission loss, effective density and effective bulk modulus) regarded here as an equivalent fluid. Second, an indirect characterization allows one to extract its non-acoustic properties (i.e., static airflow resistivity, tortuosity, viscous and thermal characteristic lengths) from the measured effective properties and the material open porosity. The procedure is applied to four different sound absorbing materials and results of the characterization are compared with existing direct and inverse methods. Predictions of the acoustic behavior using an equivalent fluid model and the found non-acoustic properties are in good agreement with impedance tube measurements.

description: Earnings Management is a practice performed by organizational employees to manipulate financial results in favor of the organization or to serve self-interests. This practice has significant implications for stakeholders such as investors, regulators, and researchers due to its impact on the integrity of financial reporting and the reliability of financial statements. While earnings management has been extensively studied in various countries, there is a lack of research within the context of Bahrain, creating a gap in the literature. This study aims to empirically investigate the elements of earnings management in Bahraini companies, providing valuable insights for investors, regulators, and corporate stakeholders. By identifying and analyzing financial factors that affect earnings management and earnings quality, the study enhances understanding within the Bahraini context. The research employs a comprehensive examination of financial data to achieve its objectives. The findings will be significant for regulators and policymakers in Bahrain, aiding in the development of effective regulations to mitigate earnings management practices. The research methodology of the study entailed a thorough examination of financial data from companies listed on the Bahrain Bourse to explore the prevalence and extent of earnings management practices, The Jeter and Shivakumar model are a paradigm for identifying earnings management utilized the data form Refinitiv for 37 listed companies in Bahrain Bourse with data from 2009 to 2023, the descriptive statistics of the key financial variables had revealed significant variability, skewness, and kurtosis, indicating the presence of outliers and non-normal distributions across the sample companies. the regression model has a very strong ability to predict the dependent variable based on the independent variables explained by R Square value 82.2% imply that a significant percentage of the variance in the dependent variable can be explained by the model.

description: We have investigated the influence of the growth parameters during molecular beam epitaxy on the realizibility of diamond crystal structure Ge / α-Sn alloys and superlattices on Ge(001) substrates. The segregation behaviour of Sn during Ge overgrowth has been studied. We find that for growth temperatures higher than 300°C the incorporation rates are less than 0.005 ML-1. The low-energy electron diffraction data of a series of Ge0.9Sn0.1 films deposited at substrate temperatures in the range of 185 to 275°C indicate a transition to amorphous growth for thicknesses beyond 20 Å. Single-crystal GenSnm superlattices with α-Sn layer thicknesses m of 1 and 2 monolayers and periodicities n + m between 10 and 22 monolayers have been fabricated by an unconventional molecular beam epitaxy technique which involves large substrate temperature modulations during growth. Structural characterization of the samples by means of transmission electron microscopy. Raman spectroscopy and X-ray diffraction exhibits distinct superlattice effects. The downward shift of the fundamental energy gap of the superlattices with increasing Sn content, as extracted from absorption measurents with a Fourier transform spectrometer, is in excellent agreement with theoretical values obtained from pseudopotential band structure calculations. The films were found to be stable against phase transition up to temperatures of 430–465°C, depending on the average Sn content.
Radio frequency CMOS : from ultra-high speed to ultra-low power

description: Over the last three decades, radio-frequency(RF) Complementary Metal-Oxide-Semiconductor(CMOS) electronics has made a huge impact in our world. Wireless Local Area Networks(WLANs), cellular networks, Global Positioning Systems(GPSs), and Bluetooth are a few examples where the impact of RF CMOS has led to rapid adoption and standardization of the technology. However, there still exists several challenging areas at the intersection of RF and CMOS where new paradigms must be established. This thesis summarizes the research to meet those goals as briefly described here: Research during the past decades provided CMOS solutions to RF applications that utilize the frequency spectrum up to 6 GHz. However, efficient system integration of mm-wave and THz in CMOS is still a challenging task. The THz spectrum is gaining interest due to its wider and less populated available spectrum, as well as its intriguing applications in molecular spectroscopy, imaging, and sensing. This band, although very useful, has been difficult to realize in hardware because of the limitations in CMOS electronics. In the first four chapters of this thesis, we investigate the challenge of implementing signal-sources at mm-wave and sub-THz frequencies using low-cost and versatile CMOS circuits, replacing the existing expensive solutions. Demand for embedded low-power electronics for wireless connectivity is growing due to the rapid proliferation of Internet-of-Things (IoT). Although Wireless Sensor Network(WSN) had been around for decades, some applications such as biomedical monitoring systems require ultra-low-power(ULP) and cost-effective wireless solutions. Research on energy-harvesting systems (e.g., RF energy harvesting, thermoelectric, etc.) and integrated-circuits(IC) bears the promise of medium-reach battery-free wireless connectivity solutions. In Chapters 5 and 6 of this thesis, multiple ULP wireless connectivity solutions for both commercial standards such as Bluetooth Low Energy(BLE) and custom-designed application-specific-radios are proposed and implemented in 40nm and 130nm CMOS technologies, respectively. Finally, application of RF electronics in power-electronics is studied in the last chapter. Although power-management integrated circuit is a well-developed field of research, PMICs still have existing bottlenecks (e.g., die area and output ripple) which can be addressed with the knowledge of RF electronics. In this thesis, feasibility of GHz-range converters is studied.

description: Here we report on measurements of the spin-Seebeck effect of GaMnAs over an extended temperature range alongside the thermal conductivity, specific heat, magnetization, and thermoelectric power. The amplitude of the spin-Seebeck effect in GaMnAs scales with the thermal conductivity of the GaAs substrate and the phonon-drag contribution to the thermoelectric power of the GaMnAs, demonstrating that phonons drive the spin redistribution. A phenomenological model involving phonon-magnon drag explains the spatial and temperature dependence of the measured spin distribution.

description: The pivot algorithm for self-avoiding walks has been implemented in a manner which is dramatically faster than previous implementations, enabling extremely long walks to be efficiently simulated. We explicitly describe the data structures and algorithms used, and provide a heuristic argument that the mean time per attempted pivot for $N$-step self-avoiding walks is $O(1)$ for the square and simple cubic lattices. Numerical experiments conducted for self-avoiding walks with up to 268 million steps are consistent with $o(\log N)$ behavior for the square lattice and $O(\log N)$ behavior for the simple cubic lattice. Our method can be adapted to other models of polymers with short-range interactions, on the lattice or in the continuum, and hence promises to be widely useful.

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We study both regular (the zero-momentum ghost dressing function not diverging), also named decoupling, and critical (diverging), also named scaling, Yang-Mills propagators solutions by analyzing the low-momentum behaviour of the ghost propagator Dyson-Schwinger equation (DSE) in Landau gauge, assuming for the truncation a constant ghost-gluon vertex, as it is extensively done, and a simple model for a massive gluon propagator. The asymptotic expression obtained for the regular or decoupling ghost dressing function up to the order ${\cal O}(q^2)$ fits pretty well the low-momentum ghost propagator obtained through the numerical integration of the coupled gluon and ghost DSE in the PT-BFM scheme and, when the size of the coupling renormalized at some scale approaches some critical value, the PT-BFM results seems to trend to the the scaling solution as a limiting case

description: BACKGROUND: Parvovirus B19 (B19V)-DNA is frequently detected in endomyocardial biopsies (EMBs) from patients with acute myocarditis (AMC) and dilated cardiomyopathy (DCM), but also in various healthy tissues. The clinical relevance of this DNA-persistence is unclear. OBJECTIVES: To investigate potential pathogenic influences of B19V-DNA in EMBs, we analyzed B19V-specific adaptive immune responses in AMC/DCM patients and healthy controls. STUDY DESIGN: 15 AMC/DCM patients with detectable B19V-DNA in EMBs and 51 controls were analyzed for signs of acute B19V-infections and virus-specific immune responses by PCR, ELISA, Western line, and ELISpot-assays. RESULTS: Productive B19V-infection was determined in three patients. Slightly lower levels of B19V-specific T-cells were observed in patients as compared to the controls, no differences were observed in virus-specific serology. Viral DNA-load in EMBs could not be correlated to the number of B19V-specific T-cells. No differences in T-cell response, viremia and/or serological markers indicative for viral pathogenesis were observed in patients with inflammatory cardiomyopathy. CONCLUSIONS: Discrepancies in B19V-specific adaptive immunity were not observed in AMC/DCM patients as compared to controls. The data indicate that the exclusive detection of B19V-DNA in EMBs is not sufficient to associate B19V with AMC/DCM but should be complemented with additional virological and immunological parameters in further studies.
Acoustic contributions of a sound absorbing blanket placed in a double panel structure: Absorption Versus Transmission
Creators: name: Doutres, Olivier

description: The objective of this paper is to propose a simple tool to estimate the absorption vs. transmission loss contributions of a multilayered blanket unbounded in a double panel structure and thus guide its optimization. The normal incidence airborne sound transmission loss of the double panel structure, without structure-borne connections, is written in terms of three main contributions; (i) sound transmission loss of the panels, (ii) sound transmission loss of the blanket and (iii) sound absorption due to multiple reflections inside the cavity. The method is applied to four different blankets frequently used in automotive and aeronautic applications: a non-symmetric multilayer made of a screen in sandwich between two porous layers and three symmetric porous layers having different pore geometries. It is shown that the absorption behavior of the blanket controls the acoustic behavior of the treatment at low and medium frequencies and its transmission loss at high frequencies. Acoustic treatment having poor sound absorption behavior can affect the performance of the double panel structure.
Dipole-dipole shift of quantum emitters coupled to surface plasmons of a nano-wire

description: Placing quantum emitters close to a metallic nano-wire, an effective interaction can be achieved over distances large compared to the resonance wavelength due to the strong coupling between emitters and the surface plasmon modes of the wire. This leads to modified collective decay rates, as well as to Lamb and dipole-dipole shifts. In this paper we present a general method for calculating these level shifts which we subsequently apply to the case of a pair of atoms coupled to the guided modes of a nano-wire.

The aim is to assist mainly the schools’ representatives (mostly Physical Education teachers and principals), as well as the representatives of organizations who can support schools on their way to become Healthy and Physically Active Schools. The toolkit contains materials structured into Core and Additional modules. The Core module contains information, materials mainly for school staff, generally for school level, and the Additional module for regional or national coordinators, organizations, that are in the position to support many schools, with the intention to build a network among the Healthy and Physically Active schools.

description: Spectroscopic ellipsometry has been used to determine the dielectric functions of ultrathin Ge/Si superlattices with varying strain states and periodicity at room temperature. The E1-like transitions could be resolved with the multiple-angle-of-incidence technique and in a thick, Ge-rich sample; they split up into various contributions and start to absorb the light at lower energies than compositionally equivalent alloys, as predicted theoretically. The E2 transitions are shifted towards lower energies and split into a doublet. Both of its components show a shift due to the hydrostatic component of the internal strain, which is approximately half of what one would expect from the corresponding deformation potentials of the constituent bulk materials. While both transitions decrease in energy with increasing period, only the lower peak shows a variation of its amplitude and broadening with period, yielding evidence for confinement effects.
