description: Отсутствие разницы в окислительно-восстановительном потенциале (ОВП) питьевой воды и воды в живом организме стимулирует биохимические процессы, происходящие в нем, активирует при-вес животных, снижает риск заболеваний, что позволит разрабатывать и применять новые технологии в животноводстве. Нами установлена высокая (100%) эффективность обеззараживания в отношении Е.coli в присутствии аналита при полном отсутствии признаков реактивации бактерий. По действующим нормативным документам может быть сделан вывод, что произошла полная инактивация тест-бактерий Е.coli и, следовательно, вода по микробиологическим показателям безопасна в эпидемическом отношении. Известен и другой способ санитарной обработки наружных поверхностей серебрение воды. Серебрение воды проводится в тех же активаторах по установленной заводом-изготовителем методике и давно используется как бактериостатический агент при длительном хранении питьевой воды на морских судах, во время космических полетов, в авиакомпаниях и т.д.The lack of oxidation-reduction potential’s difference (OBP) of drinking water and living body one stimulates its biochemical processes, activates animals’ gain, reduces the risk of diseases that will new technologies in farming to develop and apply. We have established the very high (100%) effectiveness of disinfection against E.coli in the analyte presence at the bacteria reactivation’s signs absence. As to the applicable normative documents it can be concluded that there was a test-bacteria E. coli complete inactivation and, therefore, water according to microbiological indicators is safe in the epidemic attitude. It is known an another method of external surfaces sanitary treatment-water silvering. Water silvering is held in the same activators in accordance with its plant’s made method and has long been used as a bacteriostatic agent during drinking water prolonged storage on ships, during space flights, in airlines etc.

description: We investigate the propagation of MHD fast waves into a cylindrical coronal loop through an inhomogeneous stationary flow region. The background flow is assumed to have a small, spatially periodic structure in addition to a constant speed. We focus on the absorption of the wave energy in Alfvén resonance, comparing with the constant flow case. A new flow (absorption) regime is induced by the periodic flow structure which enhances the absorption for the antiparallel flow and inverse absorption (overreflection) for the parallel flow with respect to the axial wave vector, depending on the transitional layer and flow profiles. A giant overreflection and anomalous absorption behavior arise for some flow configurations. In the other flow regimes, its effect on the absorption is shown to be weak.

Female zebra finches Taeniopygia guttata will copy the novel foraging choice of males. The degree to which they do so, however, can vary considerably. Among-individual differences in social learning and their underlying neural pathways have received relatively little attention and remain poorly understood. Here, then, we allowed female zebra finches to observe live-streamed male demonstrators feeding from one of two novel-coloured feeders (social information acquisition phase).  After this social information acquisition phase, we tested from which feeder the females preferred to feed to determine whether they copied the feeder choice of the male demonstrator (social learning test phase). We then examined the brains of these females for immediate early gene activity (c-fos) in the neural social behaviour network for the time during which they were observing the male feeding. Of the twelve regions and sub-regions in the brain examined we found only one weak correlation: greater copying was associated with lower activity the bed nucleus of the stria terminalis, BSTmv. Future work should perhaps focus on neural activity that occurs during the stage in which there is evidence that animals have copied a demonstrator (i.e., social learning test phase in the current experiment) rather than during the period in which those animal observe that demonstrator (i.e., social information acquisition phase in the current experiment. What is clear is that the considerable emphasis on examining the behavioural component of social learning has not yet been accompanied by neural analyses.

description: Using the Cornwall-Jackiw-Tomboulis effective action $Γ(S)$ for composite operators ($S$ is the full fermion propagator), the phase structure of the massless (2 + 1)-dimensional Thirring model with four-component spinors is investigated in the Hartree-Fock (HF) approximation. In this case both $Γ(S)$ and its stationary (or HF) equation for the full fermion propagator $S$ are calculated in the first order of the bare coupling constant $G$. We have shown that there exist a well-defined dependence of $G\equiv G(Λ)$ on the cutoff parameter $Λ$ under which the HF equation is renormalized. In general, it has two sets, (i) and (ii), of solutions for fermion propagator corresponding to dynamical appearance of different mass terms in the model. In the case of set (i) the mass terms are Hermitian, but the solutions from the set (ii) correspond to a dynamical generation of the non-Hermitiam mass terms, i.e. to a spontaneous non-Hermiticity of the Thirring model. Despite this, the mass spectrum of the quasiparticle excitations of all non-Hermitian ground states is real. In addition, among these non-Hermitian phases there are both $\cP\cT$ symmetrical and non-symmetrical phases. Moreover, in contrast with previous investigations of this effect in other models, we have observed the spontaneous non-Hermiticity phenomenon also in the {\it massive} (2+1)-dimensional Thirring model.

description: The distribution of multiplicity among low-mass stars is a key issue to understanding the formation of stars and brown dwarfs, and recent surveys have yielded large enough samples of nearby low-mass stars to study this issue statistically to good accuracy. Previously, we have presented a multiplicity study of ~700 early/mid M-type stars observed with the AstraLux high-resolution Lucky Imaging cameras. Here, we extend the study of multiplicity in M-type stars through studying 286 nearby mid/late M-type stars, bridging the gap between our previous study and multiplicity studies of brown dwarfs. Most of the targets have been observed more than once, allowing us to assess common proper motion to confirm companionship. We detect 68 confirmed or probable companions in 66 systems, of which 41 were previously undiscovered. Detections are made down to the resolution limit of ~100 mas of the instrument. The raw multiplicity in the AstraLux sensitivity range is 17.9%, leading to a total multiplicity fraction of 21-27% depending on the mass ratio distribution, which is consistent with being flat down to mass ratios of ~0.4, but cannot be stringently constrained below this value. The semi-major axis distribution is well represented by a log-normal function with mu_a = 0.78 and sigma_a = 0.47, which is narrower and peaked at smaller separations than for a Sun-like sample. This is consistent with a steady decrease in average semi-major axis from the highest-mass binary stars to the brown dwarf binaries.

description: Logarithmic time-like Liouville quantum field theory has a generalized PT invariance, where T is the time-reversal operator and P stands for an S-duality reflection of the Liouville field $ϕ$. In Euclidean space the Lagrangian of such a theory, $L=\frac{1}{2}(\nablaϕ)^2-igϕ\exp(iaϕ)$, is analyzed using the techniques of PT-symmetric quantum theory. It is shown that L defines an infinite number of unitarily inequivalent sectors of the theory labeled by the integer n. In one-dimensional space (quantum mechanics) the energy spectrum is calculated in the semiclassical limit and the mth energy level in the nth sector is given by $E_{m,n}\sim(m+1/2)^2a^2/(16n^2)$.

description: We present here our recent results on qubit reset scheme based on a quantum-circuit refrigerator (QCR). In particular, we use the photon-assisted quasiparticle tunneling through a superconductor--insulator--normal-metal--insulator--superconductor junction to controllably decrease the energy relaxation time of the qubit during the QCR operation. In our experiment, we use a transmon qubit with dispersive readout. The QCR is capacitively coupled to the qubit through its normal-metal island. We employ rapid, square-shaped QCR control voltage pulses with durations in the range of 2--350 ns and a variety of amplitudes to optimize the reset time and fidelity. Consequently, we reach a qubit ground-state probability of roughly 97% with 80-ns pulses starting from the first excited state. The qubit state probability is extracted from averaged readout signal, where the calibration is based of the Rabi oscillations, thus not distinguishing the residual thermal population of the qubit.

description: We use homotopy theory to extend the notion of strong and weak topological insulators to the non-stable regime (low numbers of occupied/empty energy bands). We show that for strong topological insulators in d spatial dimensions to be "truly d-dimensional", i.e. not realizable by stacking lower-dimensional insulators, a more restrictive definition of "strong" is required. However, this does not exclude weak topological insulators from being "truly d-dimensional", which we demonstrate by an example. Additionally, we prove some useful technical results, including the homotopy theoretic derivation of the factorization of invariants over the torus into invariants over spheres in the stable regime, as well as the rigorous justification of replacing $T^d$ by $S^d$ and $T^{d_k}\times S^{d_x}$ by $S^{d_k+d_x}$ as is common in the current literature.

description: The Perovskite absorber layer, the electron transport layer (ETL), the hole transport layer (HTL), and the transparent conducting oxide layer (TCO) are the major components that make up a Perovskite solar cell. Between ETL and HTL, the absorber layer is sandwiched, on which electron-hole pairs are created after absorption of solar radiation. Despite substantial progress toward efficiency, long-term stability still remains a serious concern. Present work focuses toward contributing on the later issue by adopting Titanium dioxide (TiO2) as ETL and reduced graphene oxide (rGO) as HTL. Specifically, in the present work, we report our efforts on the preparation of compact titanium dioxide (C-TiO2) and mesoporous titanium dioxide (M-TiO2) layers as an ETL and a reduced graphene oxide thin film as a HTL. The C-TiO2 film was spin casted on FTO glass followed by casting of M-TiO2 film using Doctor Blading technique. Similarly, the rGO film was produced by spray casting over the glass substrate. The as-prepared ETL and HTL layers were characterized by measuring their optical properties (transmittance and reflectance of thin films). Then, the bandgap, Eg was extracted from reflectance and transmittance curves for ETL and HTL respectively. In the case of rGO, we found the value of Eg to be 2.1 eV, which varies between 2.7eV and 0.02eV depending upon its reduction level based on the previously reported values. Similarly, the bandgap of the C-TiO2 was 4.51 eV which was reduced to 4.12 eV after the addition of M-TiO2, which are 0.9 to 1.1 eV higher than previously reported values. However, bandgap shows decreasing trend after employing M- TiO2 over C-TiO2. In a Perovskite solar cell, both ETL and HTL will be investigated.

description: Turning the weights to zero when training a neural network helps in reducing the computational complexity at inference. To progressively increase the sparsity ratio in the network without causing sharp weight discontinuities during training, our work combines soft-thresholding and straight-through gradient estimation to update the raw, i.e. non-thresholded, version of zeroed weights. Our method, named ST-3 for straight-through/soft-thresholding/sparse-training, obtains SoA results, both in terms of accuracy/sparsity and accuracy/FLOPS trade-offs, when progressively increasing the sparsity ratio in a single training cycle. In particular, despite its simplicity, ST-3 favorably compares to the most recent methods, adopting differentiable formulations or bio-inspired neuroregeneration principles. This suggests that the key ingredients for effective sparsification primarily lie in the ability to give the weights the freedom to evolve smoothly across the zero state while progressively increasing the sparsity ratio.

description: A system of two fermions with different masses and interacting by the Coulomb potential is presented in a completely covariant framework. The spin-spin interaction, including the anomalous magnetic moments of the two fermions, is added by means of a Breit term. We solve the resulting fourth order differential system by evaluating the spectrum and the eigenfunctions. The interaction vertex with an external electromagnetic field is then determined. The relativistic eigenfunctions are used to study the photon emission from a hyperfine transition and are checked for the calculation of the Lamb shift due to the electron vacuum polarization in the muonic Hydrogen.

description: Reconfigurable intelligent surfaces (RISs) have been considered as a promising technology for the sixth-generation (6G) wireless networks that can control wireless channels in a desirable way and significantly enhance the network performance. Simultaneous transmitting and reflecting-RISs (STAR-RISs) can overcome limitation of reflecting-only RISs by leveraging the higher design flexibility and full-space coverage. Despite the benefits, the modeling and analysis of STAR-RISs are complicated because of various control parameters for both transmission and reflection links. In this article, a general framework to facilitate the design and implementation of STAR-RISs in 6G scenarios and network topologies is presented. We provide a systematic introduction to the STAR-RIS operating protocols for different communication modes and discuss recent efforts to identify the research progress and combination solutions. Finally, we provide the design concepts, research challenges, potential solutions, and future directions related to the channel modeling, channel estimation, hardware implementations, modeling and limitations, and optimization.

Combined with nuclear data, these electronic parameters can be used to determine values of level and transition isotope shifts. The calculation of the electronic parameters is done using first-order perturbation theory with relativistic configuration interaction wave functions that account for valence, core-valence and core-core correlation effects as zero-order functions. Results are compared with experimental and other theoretical values, when available.

description: Background: The World Health Organization Regional Office for the Eastern Mediterranean Region established social accountability as one of its strategic directions for medical education in 2015, and individual countries have been contrib?uting to ongoing social accountability endeavours. Aims: This study aimed to identify themes related to compliance with social accountability concepts in the countries of the Eastern Mediterranean Region (EMR) based on published papers Methods: Thematic analysis of qualitative studies was done following a scoping review of published papers in the EMR over the period 1995–2021. CINAHL, Google Scholar, PubMed, Scopus, and Web of Sciences were searched along with a manual search for articles from reference lists. The Enhancing Transparency in Reporting the Synthesis of Qualitative Research ENTREQ statement guided the review. Results: The reviewed studies (n = 3) were from 3 countries in the EMR: Egypt, Saudi Arabia, and Sudan. These studies identified 7 key themes: mission and governance, communication with stakeholders, a community-oriented and commu?nity-based curriculum, provision of health services, responding to emerging community health needs, impactful faculty and student research and gaps to be addressed. Conclusions: Despite the call to reorient health profession schools to be responsive to the community and health system needs, only 3 countries in the EMR reported their efforts to move towards social accountability. Urgent action needs to be taken by medical education leaders in the Region to support colleges in their compliance with social accountability concepts.

description: The formation mechanism of the jet-aligned CO clouds found by NANTEN CO observations is studied by magnetohydrodynamical (MHD) simulations taking into account the cooling of the interstellar medium. Motivated by the association of the CO clouds with the enhancement of HI gas density, we carried out MHD simulations of the propagation of a supersonic jet injected into the dense HI gas. We found that the HI gas compressed by the bow shock ahead of the jet is cooled down by growth of the cooling instability triggered by the density enhancement. As a result, cold dense sheath is formed around the interface between the jet and the HI gas. The radial speed of the cold, dense gas in the sheath is a few km/s almost independent of the jet speed. Molecular clouds can be formed in this region. Since the dense sheath wrapping the jet reflects waves generated in the cocoon, the jet is strongly perturbed by the vortices of the warm gas in the cocoon, which breaks up the jet and forms a secondary shock in the HI-cavity drilled by the jet. The particle acceleration at the shock can be the origin of radio and X-ray filaments observed near the eastern edge of W50 nebula surrounding the galactic jet source SS433.

description: System logs are a common source of monitoring data for analyzing computing systems' behavior. Due to the complexity of modern computing systems and the large size of collected monitoring data, automated analysis mechanisms are required. Numerous machine learning and deep learning methods are proposed to address this challenge. However, due to the existence of sensitive data in system logs their analysis and storage raise serious privacy concerns. Anonymization methods could be used to clean the monitoring data before analysis. However, anonymized system logs, in general, do not provide adequate usefulness for the majority of behavioral analysis. Content-aware anonymization mechanisms such as PaRS preserve the correlation of system logs even after anonymization. This work evaluates the usefulness of anonymized system logs taken from the Taurus HPC cluster anonymized using PaRS, for behavioral analysis via recurrent neural network models.

description: A series of aryl N-[ω-(6-fluoroindol-1-yl)alkyl]carbamates with alkyl spacers of varying lengths between the indole and the carbamate group and with differently substituted aryl moieties at the carbamate oxygen were synthesized and tested for inhibition of the pharmacologically interesting serine hydrolases fatty acid amide hydrolase (FAAH), monoacylglycerol lipase (MAGL), butyrylcholinesterase (BuChE), and acetylcholinesterase (AChE). Furthermore, the chemical stability in an aqueous solution and the metabolic stability toward esterases in porcine liver homogenate and porcine blood plasma were determined. While most of the synthesized derivatives were potent inhibitors of FAAH, a considerable inhibition of MAGL and BuChE was elicited only by compounds with a high carbamate reactivity, as evidenced by a significant hydrolysis of these compounds in an aqueous solution. However, the high inhibitory potency of some compounds toward MAGL and BuChE, especially that of the 'ortho-carboxyphenyl' derivative 37, could not be explained by chemical reactivity alone. Several of the carbamates studied possessed varying degrees of stability toward esterases from liver and blood plasma. In some cases, marked inactivation by the pseudo-esterase activity of plasma albumin was observed. Mass spectrometric studies showed that such carbamates formed covalent bonds with albumin at several sites.

description: Определены технологии для интенсивного выращивания свиней и сельскохозяйственной птицы, оказывающие наибольшее негативное воздействие на окружающую среду. Исследованы эмиссии загрязняющих веществ при каждом технологическом процессе. Проанализирована законодательная база РФ в области охраны окружающей среды и подходы к выбору маркерных веществ при разработке информационно-технических справочников по наилучшим доступным технологиям (НДТ) в РФ в 2015-2016 годах. На основе проведенного анализа в качестве критерия выбора маркерных веществ предложена масса загрязняющих веществ от животноводческого комплекса (т/год) и плата за негативное воздействие на окружающую среду (руб/год). Проведенные исследования показали, что основные загрязняющие вещества на птицефабриках это аммиак, метан, пыль зерновая, диметилсульфид и сероводород; на свиноводческих комплексах метан, углерод оксид, аммиак, фосфор. На основании выбранных критериев обоснованы следующие маркерные вещества при выбросе в атмосферный воздух: для птицефабрик метан и аммиак; для свиноводческих комплексов метан, углерод оксид и аммиак. В качестве маркерных веществ, характеризующих сбросы в водные объекты, обоснованы общий азот и общий фосфор.Technologies for the farm's pigs and poultry intensive rearing that have the greatest negative impact on the environment are identified. The air pollution's emissions at each technological process influencing are investigated. The RF legal framework in the environmental protection field and the to the of marker substances choice's approaches for best available techniques (BAT) information-and-technical references' development in RF in 2015-2016 are analyzed. On the basis of the conducted analysis as the marker substances selection criterion are proposed mass of pollutants of livestock facility complex (t/year) and the environment negative impact fee (rub/year). Held studies had shown that the main contaminants on poultry farms are ammonia, methane, grain dust, dimethyl sulfide and hydrogen sulfide; at pig breeding complexes are methane, carbon monoxide, ammonia and phosphorus. Based on the selected criteria are justified the following marker substances at atmosphere release: for poultry farms there are methane and ammonia; for pig farms methane, carbon monoxide and ammonia. As marker substances characterizing the water object's discharges, are proved the total nitrogen and total phosphorus.

description: We report deep long-slit emission-line spectra, the line flux ratios, and Doppler profile shapes of various bright optical lines. The low-ionization lines (primarily [N I], [O I], [S II], and [N II]) originate in shocked knots, as reported by many previous observers. Dust-scattered lines of higher ionization are seen throughout the lobes but do not peak in the knots. Our analysis of these line profiles and the readily discernible stellar continuum shows that (1) the central star is an active symbiotic (whose spectrum resembles the central stars of highly bipolar and young PNe such as M2-9 and Hen2-437) whose compact companion shows a WC8-type spectrum, (2) extended nebular lines of [O III] and He I originate in the heavily obscured nuclear H II region, and (3) the Balmer lines observed throughout the lobes are dominated by reflected Hα emission from the symbiotic star. Comparing our line ratios with those observed historically shows that (1) the [O III]/H\b{eta} and He I/H\b{eta} ratios have been steadily rising by large amounts throughout the nebula, (2) the Hα/H\b{eta} ratio is steadily decreasing while Hγ/H\b{eta} remains nearly constant, and (3) the low-ionization line ratios formed in the shocked knots have been in decline in different ways at various locations. We show that the first two of these results might be expected if the symbiotic central star has been active and if its bright Hα line has faded significantly in the past 20 years.

description: Offline reinforcement learning (RL) enables the agent to effectively learn from logged data, which significantly extends the applicability of RL algorithms in real-world scenarios where exploration can be expensive or unsafe. Previous works have shown that extracting primitive skills from the recurring and temporally extended structures in the logged data yields better learning. However, these methods suffer greatly when the primitives have limited representation ability to recover the original policy space, especially in offline settings. In this paper, we give a quantitative characterization of the performance of offline hierarchical learning and highlight the importance of learning lossless primitives. To this end, we propose to use a \emph{flow}-based structure as the representation for low-level policies. This allows us to represent the behaviors in the dataset faithfully while keeping the expression ability to recover the whole policy space. We show that such lossless primitives can drastically improve the performance of hierarchical policies. The experimental results and extensive ablation studies on the standard D4RL benchmark show that our method has a good representation ability for policies and achieves superior performance in most tasks.

Intercitizenship: how contemporary women writers create literary environmentalism across the U.S.-Canada border
Creators: name: Jocelyn, Hannah
Publisher: name: No Publisher Supplied
Year: 2024

description: This dissertation is a study of four contemporary, white women writers who have lived on both sides of the northern North American border: Annie Proulx, Elizabeth Hay, Lydia Millet, and Emily St. John Mandel. Its key intervention is the establishment and modelling of “intercitizenship,” which is both a literary category of analysis and a way of seeing and being in place. Drawing on borderlands scholarship, citizenship studies, critical place inquiry, Indigenous epistemologies, feminist theory, and ecocriticism, I argue that these writers—whom I term “intercitizens”—embody in their lives and imagine in their work a worldview that is relational, decolonial, and liberated from boundaries of nationality, space, species, and so on. Intercitizens are identifiable by their affective use of solastalgia (the homesickness one feels at home as the environs are despoiled), and by three literary themes: homes in disrepair, protagonists in motion, ecosystems in danger. Together these themes produce a feminist un-homing. The literary environmentalism of the writers featured here is funneled through deep-landscape and uncanny writing. As an assemblage, intercitizens are aware of and share settler histories, subjugated Indigenous knowledges, and the ongoing colonial apparatuses embedded in capitalistic, nationalistic, heteropatriarchal society—and they are critical of the powers sublimating that history and knowledge. In re-envisioning community, intercitizenship is at once disruptive and productive—a tool wielded toward a cultural reset in which our common values include decoloniality, interrelationality, and cross-border care for the Earth and every constituent (human and more-than-human) of its varied and threatened ecosystems.

description: We show that both flavor-conserving and flavor-violating Yukawa couplings of the Higgs boson to first- and second-generation quarks can be probed by measuring rare decays of the form h->MV, where M denotes a vector meson and V indicates either gamma, W or Z. We calculate the branching ratios for these processes in both the Standard Model and its possible extensions. We discuss the experimental prospects for their observation. The possibility of accessing these Higgs couplings appears to be unique to the high-luminosity LHC and future hadron colliders, providing further motivation for those machines.

description: Probability distribution modeling is the basis for most competitive methods for lossless coding of screen content. One such state-of-the-art method is known as soft context formation (SCF). For each pixel to be encoded, a probability distribution is estimated based on the neighboring pattern and the occurrence of that pattern in the already encoded image. Using an arithmetic coder, the pixel color can thus be encoded very efficiently, provided that the current color has been observed before in association with a similar pattern. If this is not the case, the color is instead encoded using a color palette or, if it is still unknown, via residual coding. Both palette-based coding and residual coding have significantly worse compression efficiency than coding based on soft context formation. In this paper, the residual coding stage is improved by adaptively trimming the probability distributions for the residual error. Furthermore, an enhanced probability modeling for indicating a new color depending on the occurrence of new colors in the neighborhood is proposed. These modifications result in a bitrate reduction of up to 2.9% on average. Compared to HEVC (HM-16.21 + SCM-8.8) and FLIF, the improved SCF method saves on average about 11% and 18% rate, respectively.

description: This study investigates the impacts of agricultural R&D on farm income in Korea. We constructed a decomposition method where farm income change was decomposed into the four effects of output price change, input price change, productivity change and production scale change. Before the decomposition method was applied, the impacts of the R&D expenditure on the changes in output prices, input prices, total factor productivity, and factor-bias were econometrically estimated. We found that the agricultural R&D expenditure negatively affected farm income by reducing agricultural product prices substantially. On the other hand, the agricultural R&D expenditure resulted in a saving in cost by reducing input prices and enhancing productivity. An increase in production scale owing to the R&D expenditure also contributed to farm income slightly. The sum of the positive effects of input price decline, productivity change, and scale change of the agricultural R&D dominated the negative effect of output price decline. Finally, it was found that the R&D effects are substantially variant across farm households depending on their choice of products, input shares, farmland size, and production location.
