Authors: Almurzaeva P.Kh. , Kasumova B.S.-A. , Kasumova L.A.
Published: July 2023

The article deals with the concept of morality in English linguoculture. The analysis shows that the concept of «morality» covers concepts that reflect the value ideas of the British people about what is moral and ethical in society. In the process of analyzing the means of verbalization of the concept «morality» in speech, we have identified the following lexical units that represent the concept - good, goodness, responsibility, code of conduct, love, patience, etc. The results of the study indicate that «morality» in the English linguoculture is associated with such concepts as – compliance with the norms of behavior and the law, love, patience, intelligence, awareness, dignity, honesty. Associative components of certain qualities are the following: reliability, willpower, decency, nobility, benevolence, etc..

Published: July 2023

The 18th century is a turning point in the history of the peoples of the Caucasus. The progressive decline of Iran and the Ottoman Empire, the active entry of Peter’s Russia into the international arena put the question of the fate of the Caucasus among the most important problems of world politics at that time. Having become one of the main sources of contradictions in the relations of these countries, this region, due to its important strategic positions, attracted the attention of European powers, primarily England and France.

Authors: Meadows Vik , Yang Zhenning , Basaly Veronia , Guo Grace L.
Published: July 2023

Chronic liver diseases encompass a wide spectrum of hepatic maladies that often result in cholestasis or altered bile acid secretion and regulation. Incidence and cost of care for many chronic liver diseases are rising in the United States with few Food and Drug Administration-approved drugs available for patient treatment. Farnesoid X receptor (FXR) is the master regulator of bile acid homeostasis with an important role in lipid and glucose metabolism and inflammation. FXR has served as an attractive target for management of cholestasis and fibrosis; however, global FXR agonism results in adverse effects in liver disease patients, severely affecting quality of life. In this review, we highlight seminal studies and recent updates on the FXR proteome and identify gaps in knowledge that are essential for tissue-specific FXR modulation. In conclusion, one of the greatest unmet needs in the field is understanding the underlying mechanism of intestinal versus hepatic FXR function.

Authors: Cooper Shawna A. , Kostallari Enis , Shah Vijay H.
Published: July 2023

Liver sinusoidal endothelial cells (LSECs) are key players in maintaining hepatic homeostasis. They also play crucial roles during liver injury by communicating with liver cell types as well as immune cells and promoting portal hypertension, fibrosis, and inflammation. Cutting-edge technology, such as single cell and spatial transcriptomics, have revealed the existence of distinct LSEC subpopulations with a clear zonation in the liver. The signals released by LSECs are commonly called “angiocrine signaling.” In this review, we summarize the role of angiocrine signaling in health and disease, including zonation in healthy liver, regeneration, fibrosis, portal hypertension, nonalcoholic fatty liver disease, alcohol-associated liver disease, aging, drug-induced liver injury, and ischemia/reperfusion, as well as potential therapeutic advances. In conclusion, sinusoidal endotheliopathy is recognized in liver disease and promising preclinical studies are paving the path toward LSEC-specific pharmacotherapies.
Edwardsiella tarda Causing Fishbone Injury Cellulitis Leading to Sepsis in a Case of Hematological Malignancy—A Rare Report and Review of Literature
Authors: Sarathi Sushree , Brahma Anupam , Das Prabodha Kumar , Mahapatra Ashoka , Behera Bijayini
Published: July 2023

Edwardsiella tarda (E. tarda), a gram-negative bacillus, a member of order Enterobacterales, is typically a fish pathogen frequently isolated from fresh and brackish water environments. It is very rarely implicated in human infections such as gastroenteritis (most common), cellulitis, gas gangrene, hepatobiliary infections, peritonitis, empyema, and meningitis. Bacteremia/sepsis caused by E. tarda can be fatal in humans, although very rare (<5%). To date, very few cases of E. tarda sepsis have been reported worldwide including India. We report a rare case of cellulitis caused by E. tarda following fishbone injury in a patient with underlying hematological malignancy leading to sepsis.
Recurrent Nasopharyngeal Carcinoma and the Role of Surgery
Authors: Saraswathula Anirudh , London Nyall R.
Published: July 2023

Recurrent nasopharyngeal carcinoma (rNPC) presents unique challenges as reirradiation comes with significant treatment-related morbidity in swallowing, middle ear function, and large-vessel integrity. Advances in endoscopic technology have made surgery for rNPC an increasingly viable option for select patients and may play a role in providing a better quality of life to patients with this challenging disease. In carefully selected patients, endoscopic and open surgical approaches may provide comparable disease control while mitigating long-term treatment-related morbidity.

Published: July 2023

Background Distal radius fractures are commonly seen among the elderly, though studies examining their long-term outcomes are limited.

Purpose The aim of this study was to describe the 5-year trajectory of recovery of distal radius fractures treated with open reduction and internal fixation (ORIF).

Methods Patients with distal radius fractures (AO/OTA 23.A-C) treated by ORIF were prospectively studied. Patient-Rated Wrist Evaluation (PRWE) score was measured at baseline (preinjury recall) and postoperatively at 6 months, 1 year, and 5 years. Clinically relevant change in PRWE score was assessed using the minimal clinically important difference (MCID).

Results A total of 390 patients were included, of which 75% completed 5-year follow-up. Mean baseline PRWE score was 1.25 (standard deviation, SD: 2.9). At 6 months, mean PRWE score was at its highest up to 20.2 (SD: 18.4; p < 0.01). A significant improvement in mean PRWE score was observed at 1 year down to 15.2 (SD: 17.6; p < 0.01); 44% of patients were still one MCID outside of their baseline PRWE score at 1 year. Further significant improvement in mean PRWE score occurred at 5 years down to 9.4 (SD: 13.4; p < 0.01); 29% of patients remained one MCID outside of their baseline PRWE score at 5 years.

Conclusion Recovery after ORIF for distal radius fractures showed significant worsening after surgery, followed by significant improvements up to 1 year and between years 1 and 5, albeit to a lesser extent. Statistically and clinically relevant wrist pain and disability persisted at 5 years. Future research should examine different treatment modalities and include a nonoperative treatment arm for comparison.

Counter-terrorism training for business in UK crowded places: is the desire for quantity to the detriment of quality?
Authors: Aplin Dylan , Brooke Rogers M.
Published: July 2023

There is a dearth of evidence to indicate the effectiveness of counter-terrorism (CT) training for workers in crowded places to achieve their objectives of preventing attacks, helping staff to cope in a critical incident and then return to some form of normality afterwards. This study conducted semi-structured interviews (N = 23) of key stakeholders involved in devising, commissioning, and delivering CT programmes. It was found that lack of regard for adult learning theory, the skills and experience that particularly security officers bring to sessions and a complete absence of structured evaluation mean that the desire to increase the quantity of sessions delivered was to the detriment of quality. A series of recommendations are made to improve the future development and delivery of CT programmes to improve resilience.

We report on the first experiment dedicated to the study of nuclear reactions on dopants in a cryogenic capsule at the National Ignition Facility (NIF). This was accomplished using bromine doping in the inner layers of the CH ablator of a capsule identical to that used in the NIF shot N140520. The capsule was doped with 3 × 1016 bromine atoms. The doped capsule shot, N170730, resulted in a DT yield that was 2.6 times lower than the undoped equivalent. The Radiochemical Analysis of Gaseous Samples (RAGS) system was used to collect and detect 79Kr atoms resulting from energetic deuteron and proton ion reactions on 79Br. RAGS was also used to detect 13N produced dominantly by knock-on deuteron reactions on the 12C in the ablator. High-energy reaction-in-flight neutrons were detected via the 209Bi(n,4n)206Bi reaction, using bismuth activation foils located 50 cm outside of the target capsule. The robustness of the RAGS signals suggests that the use of nuclear reactions on dopants as diagnostics is quite feasible.
DC electric field generation and distribution in magnetized plasmas
Authors: Rax Jean-Marcel , Gueroult Renaud , Fisch Nathaniel J.
Published: July 2023

Very large DC and AC electric fields cannot be sustained between conducting electrodes because of volume gas breakdown and/or surface field emission. However, very large potential fields are now routinely generated in plasma structures, such as laser generated wake in unmagnetized plasmas. In magnetized plasmas, large DC fields can also be sustained and controlled perpendicular to the magnetic field, but the metallic end plates limiting the plasma, terminating the magnetic field lines, and usually providing the voltage drop feed between the field lines impose severe restrictions on the maximum field. However, it is shown that very large radial DC voltage drops can be sustained by injecting waves of predetermined frequencies and wave vectors, traveling along the azimuthal direction of an axially magnetized plasma cylinder, or by injecting fast neutral particles beams along this azimuthal direction. The large conductivity along the magnetic field lines and the small conductivity between the field lines then distribute this voltage drop. The global power balance and control parameters of wave and beam generated large DC electric fields in magnetized plasmas are identified, described, and analyzed.
Characterization of coupled parallel flow through layered heterogeneous porous media
Authors: Alokaily Samer A.
Published: July 2023

In this paper, numerical simulations are used to investigate the flow fields that develop within a triple-layer channel. The middle layer, with flow governed by Navier–Stokes equations, is sandwiched between two heterogeneous permeable layers, with flow governed by well-known non-Darcy type models such as Darcy–Lapwood–Brinkman (DLB) and Darcy–Lapwood–Forchheimer–Brinkman (DFB). As a function of the normal space variable, it is proposed that the permeability varies continuously and logarithmically across the channel and reaches zero on solid walls. All computations are carried out with the open source software package OpenFOAM. In the case of constant permeability, the computations are first validated by comparison to data from earlier literature and homotopy analysis method results. Then, for the case of heterogeneous porous media, a computational investigation is performed to examine the effects of specific geometrical, media, and flow parameters on the quantities of interest, namely, interfacial strain rate and velocity. Specifically, the effect of Darcy number, Reynolds number, porous media model, pressure gradient, free-space layer thickness, symmetry adjustment parameter, and Forchheimer coefficient is determined. It is found that interfacial velocity scales with pressure gradient and Reynolds number for low Reynolds numbers, increases with the Darcy number, and decreases as the Forchheimer coefficient increases. For low Reynolds numbers, the interfacial strain rate is found to scale with pressure gradient, Reynolds number, and free-space layer thickness. Furthermore, the interfacial strain rate is found to be independent of Darcy number when the bounding porous layers have the same thickness, Darcy number, or model equation.
Resonant dynamics of one-side multipactor on dielectric
Authors: Romanov Gennady
Published: July 2023

Breakdown of dielectric radio frequency (RF) windows is an important issue for particle accelerators and high-power RF sources. One of the common reasons for RF window failure is the multipactor on a dielectric surface. The multipactor may be responsible for excessive heating of the dielectric and discharge of charges that accumulated in the ceramic due to secondary emission. In this study, comprehensive self-consistent particle-in-cell simulations with space charge effect were performed. This was to better understand the dynamic of one-side multipactor development and floating potential on the dielectric induced by the emission. The important correlations between the multipactor parameters at saturation, the secondary emission properties of dielectric, and the applied RF field parameters have been found, which led to the conclusion that the dynamics of one-side multipactor on dielectric is a resonant phenomenon.
Global gyrokinetic simulation for toroidal impurity mode turbulence
Authors: Muto Mikiya , Imadera Kenji
Published: July 2023

In this study, global gyrokinetic simulations of the toroidal impurity mode (tIM) turbulence are performed. A linear analysis shows that the tIM is an instability that occurs in the bad curvature region when the density gradients of bulk ions and impurities are in opposite directions. The tIM can be unstable even when the temperature profiles are flat. In the presence of temperature gradients, the tIM and toroidal ion temperature gradient (tITG) mode could coexist. For the small temperature gradient, the tIM is found to be dominant. The tIM turbulence drives the large inward impurity and outward ion particle transports. Furthermore, the inward ion heat flux driven by the tIM turbulence causes the ion temperature profile to be more peaked than the initial one. For the large temperature gradient, while such inward ion heat flux does not occur because of the dominant tITG mode, the large inward impurity and outward ion particle fluxes are still observed due to the subdominant tIM. These results indicate that the tIM plays an important role in turbulent heat and particle transport when impurities are injected.
Nucleation of helium in pure liquid lithium
Authors: Álvarez-Galera Edgar , Martí Jordi , Mazzanti Ferran , Batet Lluís
Published: July 2023

Tritium self-sufficiency in fusion nuclear reactors will be based on the neutron capture by lithium in the so-called breeding blankets of the reactor, a nuclear reaction that will produce helium along with tritium. The low solubility of helium in liquid metals could cause the eventual formation of helium bubbles, which may have a negative impact on the performance of the breeding blanket in a way that has yet to be fully understood. In this work, we provide deep insight into the behavior of lithium and helium mixtures at experimentally operating conditions (800 K and pressures between 1 and 100 bars) using a microscopic model suitable to describe the interactions between helium and lithium at the atomic level, in excellent agreement with available experimental data. The simulations predict the formation of helium bubbles with radii around 10 Å at ambient pressure with surface tension values in the range of 0.6–1.0 N/m. We also report the cohesive energies of helium and the work of formation of the cluster of atoms, as well as a quantitative estimation of the Hildebrand and Kumar cohesion parameters. Our results indicate that the segregation between He and Li atoms is strong, and once a bubble is formed, it never dissociates.

Published: July 2023

The small current detection circuit is the core component of the accurate detection of the nanopore sensor. In this paper, a compact, low-noise, and high-speed trans-impedance amplifier is built for the nanopore detection system. The amplifier consists of two amplification stages. The first stage performs low-noise trans-impedance amplification by using ADA4530-1, which is a high-performance FET operational amplifier, and a high-ohm feedback resistor of 1 GΩ. The high pass shelf filter in the second stage recovers the higher frequency above the 3 dB cutoff in the first stage to extend the maximum bandwidth up to 50 kHz. The amplifier shows a low noise below sub-2 pA rms when tuned to have a bandwidth of around 5 kHz. It also guarantees a stable frequency response in the nanopore sensor.
Thermal properties of nanoporous materials, large scale modelling with the use of Monte Carlo phonon transport autocorrelation
Authors: Lacroix D. , Nkenfack M. I. , Pernot G. , Isaiev M.
Published: July 2023

In the present work, we demonstrate the ability of a technique based on Monte Carlo resolution of the Boltzmann transport equation associated to the Green–Kubo autocorrelation of the phonon heat flux to predict, at thermal equilibrium, the thermal conductivity tensor of nanoporous structures. This methodology, which is derived from a former work [D. Lacroix, M. Isaiev, G. Pernot, Phys. Rev. B 104, 165 202 (2021)] developed in the case of bulk systems, is used to predict thermal transport properties of Si porous matrices and Si phononic membranes at room temperature. A broad range of porosities and different pore network organizations are considered. Our results are compared to available experimental data and former modeling techniques. In addition, analytical models based on the phonon mean free path are detailed and compared to numerical simulations.
Chirality-controlled spin scattering through quantum interference
Authors: van Ruitenbeek Jan M. , Korytár Richard , Evers Ferdinand
Published: July 2023

Chirality-induced spin selectivity has been reported in many experiments, but a generally accepted theoretical explanation has not yet been proposed. Here, we introduce a simple model system of a straight cylindrical free-electron wire containing a helical string of atomic scattering centers with spin–orbit interaction. The advantage of this simple model is that it allows deriving analytical expressions for the spin scattering rates, such that the origin of the effect can be easily followed. We find that spin-selective scattering can be viewed as resulting from the constructive interference of partial waves scattered by the spin–orbit terms. We demonstrate that forward scattering rates are independent of spin, while back scattering is spin dependent over wide windows of energy. Although the model does not represent the full details of electron transmission through chiral molecules, it clearly reveals a mechanism that could operate in chiral systems.
Stopping power of high-density alpha-particle clusters in partially degenerated deuterium–tritium fuels

Published: July 2023

The state of burning plasma had been achieved in inertial confinement fusion (ICF), which was regarded as a great milestone for high-gain laser fusion energy. In the burning plasma, alpha particles incident on the cryogenic (warm dense) fuels cannot be simply regarded as single particles, and the new physics brought about by the density effects of alpha particles should be considered. In this work, the collective interaction between them has been considered, namely, the effect of the superposition of wake waves. The stopping power of alpha-particle clusters, i.e., the rate of energy loss per unit distance traveled has been calculated using both analytical and simulation approaches. In theory, we obtain the stopping power of alpha clusters in cryogenic (warm dense) fuel by the dielectric function method, which illustrates the importance of the effective interaction between particles. Simulation results using the LAPINS code show that the collective stopping power of the alpha cluster is indeed increased via coherent superposition of excitation fields (the excitation of high-amplitude wake waves). However, the comparison between simulation and theoretical results also illustrates a coherent–decoherent transition of the stopping power of the cluster. The initial conditions with various sizes and densities of the alpha clusters have been considered to verify the condition of decoherence transition. Our work provides a theoretical description of the transport properties of high-density alpha particles in warm dense cryogenic fuel and might give some theoretical guidance for the design of actual fusion processes.

Published: July 2023

The nonadiabatic interactions between the C̃ state and neighboring electronic states of SO2 have attracted much attention; however, the predissociation mechanisms are not yet completely understood. In this work, the predissociation dynamics of SO2 via its C̃ state have been investigated at λ = 193–201 nm by using the time-sliced velocity map ion imaging technique. The translational energy distributions and the branching ratios of the O(3PJ=2,1,0) spin–orbit products at six photolysis wavelengths have been acquired. The SO(3Σ−) product population gradually decreases in v = 0 and increases in v = 2 as the photolysis wavelength decreases. The branching ratios of O(3P J=2,1,0) products are almost similar at most wavelengths, except at 194.8 nm. Our data suggest that the predissociation between 193 and 201 nm is via an avoided crossing between the C̃ state and the repulsive triplet 23A′ state. The state-to-state dynamical pictures shown in this work provide a rigorous test of the potential energy surfaces (PESs) of the SO2 and the nonadiabatic couplings between these PESs.
Large damping-like torque and efficient current-induced magnetization reversal in Ti/Tb–Co/Cr structures
Authors: Guo Yonghai , Zhang Yu , Lv Wenbo , Wang Bo , Zhang Bo , Cao Jiangwei
Published: July 2023

Seeking the magnetic heterostructures with large current-induced torque efficiency is currently one of the core hotspots in spintronics. In this work, we report the large and composition-dependent damping-like (DL) torque in the structure consisting of light metal Cr and Ti layers and a ferrimagnetic Tb–Co layer. The DL torque efficiency in the structures reaches a maximum (around −0.55) as the Tb content in the Tb–Co layer is in the range of 0.15–0.18. This composition-dependent behavior is different from that observed in the usual heavy-metal/ferrimagnetic structures. We also demonstrated the efficient current-induced magnetization reversal in these structures with a low threshold current density down to 8×1010 A/m2. In comparison, only very low efficiency values of −0.06 and −0.086 are obtained in the Ti/Co/Cr and Ti/Tb–Co/SiN control samples, respectively, suggesting that the large DL torque in the Ti/Tb–Co/Cr structures may originate from the orbital Hall effect in the Cr metal. By fitting the Cr layer thickness dependence of the torque efficiency with a simple orbital current diffusion model, we obtained an effective orbital Hall angle of −0.57±0.02 for the Ti/Tb0.85Co0.15/Cr samples. This work demonstrated the possibility to enhance the orbital torque effect by using the magnetic layer containing the element with strong spin–orbit coupling.
Theory of electrolyte solutions in a slit charged pore: Effects of structural interactions and specific adsorption of ions
Authors: Vasileva Victoria A. , Mazur Daria A. , Budkov Yury A.
Published: July 2023

In this paper, we present a continuation of our research on modeling electrolyte solutions within charged pores. We make use of the model developed by Blossey et al. [Phys. Rev. E 95, 060602 (2017)], which takes into account the structural interactions between ions through a bilinear form over the gradients of local ionic concentrations in the grand thermodynamic potential, as well as their steric interactions through the lattice gas model. The structural interactions may describe the effects of the molecular structure of ions at a phenomenological level. For example, these effects include steric effects due to non-spherical shapes of ions, their conformational lability, and solvent effects. In addition, we explore their specific interactions with the pore walls by incorporating external attractive potentials. Our primary focus is on observing the behavior of ionic concentration profiles and the disjoining pressure as the pore width changes. By starting with the local mechanical equilibrium condition, we derive a general expression for the disjoining pressure. Our findings indicate that considering the structural interactions of ions leads to a pronounced minimum on the disjoining pressure profiles at small pore widths. We attribute this minimum to the formation of electric double layers on the electrified surfaces of the pore. In addition, our results demonstrate that the inclusion of the attractive interactions of ions with the pore walls enhances this minimum and shifts it to smaller pore thicknesses. Our theoretical discoveries may be useful for those involved in supercapacitor electrochemical engineering, particularly when working with porous electrodes that have been infused with concentrated electrolyte solutions.
On the propagation of cnoidal wave and overtaking collision of slow shear Alfvén solitons in low

Published: July 2023

The overtaking collisional phenomenon of slow shear Alfvén solitons are studied in a low beta (β = kinetic pressure/magnetic pressure) collisionless, magnetized plasma consisting of electron and ion fluids. By employing a reductive perturbation technique, the Korteweg–de Vries (KdV) equation is deduced for investigating the nonlinear slow shear Alfvén wave. Before embarking on the study of the overtaking collisions, the stability analysis of the KdV equation is studied using the bifurcation theory. Also, a nonlinear periodic solution of the KdV equation is derived for the first time in the Weierstrass elliptic function formula. Moreover, the condition for converting the Weierstrass elliptic function expression to soliton is discussed. Furthermore, it is found that only density dip (rarefactive) solitons are formed in the super-Alfvénic regime. The next step includes the use of the Hirota bilinear method, which results in two and three shear Alfvén soliton solutions and their subsequent phase shifts. The influence of the plasma parameters on the amplitude as well as width of the slow shear Alfvén wave solitons are examined analytically and numerically. We also find out the profiles of overtaking interaction of slow shear Alfvén dip solitons having different amplitudes and speeds numerically. This study is important for understanding the phenomena of nonlinear slow shear Alfvén wave structures both in space and in laboratory plasmas.
Effects of uniform and periodic magnetic fields at the nonlinear stability of three magnetic fluids in porous media
Authors: Moatimid Galal M. , Sayed Aya , Zekry Marwa H.
Published: July 2023

The current manuscript tackles the interaction between three viscous magnetic fluids placed on three layers and saturated in porous media. Two of them fill half of the spaces above and below a thin layer that lies in the middle region. All layers are laterally extended to infinity in both horizontal directions. All fluids move in the same horizontal direction with different uniform velocities and are driven by pressure gradients. The system is stressed by tangential stationary/periodic magnetic fields. The viscous potential theory is used to simplify the mathematical procedure. The motion of the fluids is described by the Brinkman–Darcy equations, and Maxwell equations are used for the magnetic field. The work has been motivated in light of the engineering applications like petroleum products manufacturing and the electromagnetic field effect that can be used to control the growth of the perturbation and then the recovery of crude oil from the pores of reservoir rocks. The nonlinear technique typically relies on solving linear equations of motion and presenting the nonlinear boundary conditions. The novelty of the problem concerns the nonlinear stability of the double interface under the impact of periodic magnetic fields. Therefore, the approach has resulted in two nonlinear characteristic differential equations governing the surface displacements. Accordingly, the development amplitudes of surface waves are designated by two nonlinear Schrödinger equations. Stability is theoretically analyzed; the nonlinear stability criteria are derived, and the corresponding nonlinear stability conditions are explored in detail. The analysis reveals the resonance as well as the non-resonance situations. Approximate bounded solutions of the perturbed interfaces are estimated. It is found that the thickness of the intermediate layer is represented as a function of time and plotted. The impact of different parameters on the stability profile is investigated. For the middle layer, it is observed that magnetic permeability and viscosity have a stabilizing effect. By contrast, basic streaming and permeability have a destabilizing influence. Due to different saturation amplitude at each case, the analysis of the periodic case shows that the lower interface is much more stable than the upper one.
Quantum evolution represented by Brownian motion
Authors: Shao Jiushu
Published: July 2023

We propose a stochastic Schrödinger equation in which the momentum is coupled to a white Gaussian noise. In the stochastic representation, the kinetic energy representing the self-interaction of momentum is reduced to a linear term of momentum. As such, the quantum evolution operator factorizes into two contributions due to the momentum and the potential, respectively. The exact quantum propagator thereby becomes an expectation of the stochastic one in which the amplitude results from the potential with a fluctuating position: The particle moves with a constant velocity, subjected to a complex Brownian motion. We demonstrate that the stochastic Schrödinger equation can be feasibly used to derive the quantum propagators for the linear potential and the harmonic oscillator system. Novel semiclassical and other approximations may be developed from the new representation of quantum mechanics.
Simulation study of coaxial virtual cathode oscillator as a THz source
Authors: Zamani R. , Shokri B.
Published: July 2023

In this paper, a coaxial virtual cathode oscillator (vircator) is simulated by the particle-in-cell method for the terahertz (THz) band. THz waves have many applications in human life, and many researchers work on related technologies, especially on THz sources like vacuum electronic devices (VEDs). A vircator is a kind of VED that is usually operated at a few GHz, but in this study, a coaxial vircator is proposed as a THz source for the first time. By adding a reflector and center rod to the base coaxial configuration and optimizing the parameters, an output power of about 29 W is achieved at 0.25 THz with the dominant mode of TM01. Working voltage and current are 26 kV and 100 mA, respectively. In addition, to indicate the scalability of the device, two other designs for higher and lower frequencies are simulated. Simplicity is one of the important advantages of the proposed THz coaxial vircator in comparison to other THz sources.
Give it to her

Pornography is commonly criticized for allegedly representing and promoting sexual dominance of men over women.
Studies have shown varying results, with no scientific consensus reached on the matter. To contribute to the discussion with
empirical discourse analysis evidence, I examine the linguistic choices reflected in a corpus of erotic novels to test whether
there are gendered patterns of agency in the representation of sexual interactions. The construal of prominence is correlated to
the notion of agency to find which participant specifies the trajector status and agent role in every relational expression.
Results show that male participants take prominence over females in an overwhelming majority of the cases, while expressions with
plural agency are marginal. The approach of this paper, combining cognitive grammar with linguistic participation roles, provides
comprehensive and realistic results by attempting to operationalize agency as the linguistic expression of a particular cognitive
pathway.
Reciprocal constructions
Authors: Yakpo Kofi
Published: July 2023

This study analyzes the borrowing of Dutch reciprocal pronouns in a corpus of primary field data of Sranan,
Sarnami, and Surinamese Javanese, three languages of Suriname. The expression of reciprocity in relevant African and Asian
substrates of the languages under study is also presented and discussed. I suggest cognitive and sociolinguistic explanations for
the preference of Dutch-sourced reciprocal pronouns during multilingual contact. The three languages show convergent borrowing
processes favoring the dedicated Dutch reciprocal pronoun over ‘scattered’ native strategies. Further, Suriname is a hierarchical
post-colonial language ecology in which borrowing proceeds mostly in one direction, either directly from Dutch, or from Dutch via
Sranan. The parallel multilingual trajectory of contact-induced change in the expression of a complex notion like reciprocity
showcases the attractiveness for borrowing of forms and structures with transparent relations between form and content.
Characterisation of thin α-Al2O3 tribo-coating deposited by low-power gas tunnel plasma spray
Authors: Abd Halim Zulhelmi Alif , Ahmad Norhayati
Published: July 2023

This study used a unique, low-power (2.8 kW) gas tunnel plasma spray and γ-Al2O3 feedstock powder to deposit a thin Al2O3 coating (<2 µm) on mild steel substrate. By optimising the plasma gas flow rate, powder feed rate, spraying time, and distance, a dense and homogeneous Al2O3 coating was obtained at a very high deposition rate (150 nm/s). During plasma coating, the high energy density plasma transforms the γ-Al2O3 powder into a highly crystalline α-Al2O3 as the predominant microstructure of the coating. The performance of the Al2O3 coating on mild steel was then evaluated preliminary using a linear sliding wear test against a chrome-steel ball, with the results indicating an 18–26% reduction in wear when compared to the uncoated substrate.

Capsinoids may exert ergogenic effects on resistance exercises. However, the acute effects of capsinoids on neuromuscular performance in humans are unknown. Here, we aimed to investigate the acute effects of dihydrocapsiate on lower‐ and upper‐body neuromuscular performance parameters in resistance‐trained individuals. 25 young adults (n = 6 women; age = 26 ± 3 years; body mass index = 24.3 ± 2.8 kg/m2) with ≥ 1‐year resistance training experience were included in this triple‐blind (participants, intervention researchers, and data analysts were blinded), placebo‐controlled, crossover study. Lower‐ and upper‐body ballistic strength (countermovement jump [CMJ] height and bench press throw [BPT] peak velocity), maximum dynamic strength (estimated 1 repetition maximum in squat and bench press [BP]), and strength‐endurance (mean set velocity [squat] and number of repetitions to failure [bench press]) were assessed in 2 independent sessions (≥7 days separation). Participants ingested 12 mg of dihydrocapsiate or placebo 30 min before each trial. We found no significant differences between dihydrocapsiate and placebo conditions in ballistic strength, (CMJ height 33.20 ± 8.07 vs 33.32 ± 7.85 cm; BPT peak velocity 2.82 ± 0.77 vs 2.82 ± 0.74 m/s) maximal dynamic strength (estimated squat 1RM: 123.76 ± 40.63 vs 122.66 ± 40.97 kg; estimated BP 1RM: 99.47 ± 43.09 vs 99.60 ± 43.34 kg), and strength‐endurance (squat mean set velocity 0.66 ± 0.07 vs 0.66 ± 0.05 m/s; number BP repetitions to failure 13.00 ± 3.56 vs 13.00 ± 4.78) (allP ≥ 0.703). We conclude that dihydrocapsiate does not acutely improve neuromuscular performance in trained young adults.
Spin-polarization control of in-plane scattering in arrays of asymmetric U-shaped nanoantennas

We study projection-enabled enhancement of asymmetric optical responses of plasmonic metasurfaces for photon-spin control of their far field scattering. Such a process occurs by detecting the light scattered by arrays of asymmetric U-shaped nanoantennas along their planes (in-plane scattering). The nanoantennas are considered to have relatively long bases and two unequal arms. Therefore, as their view angles along the planes of the arrays are changed, they offer an extensive range of shape and size projections, providing a wide control over the contributions of plasmonic near fields and multipolar resonances to the far field scattering of the arrays. We show that this increases the degree of the asymmetric spin-polarization responses of the arrays to circularly polarized light, offering a large amount of chirality. In particular, our results show the in-plane scattering of such metasurfaces can support opposite handedness, offering the possibility of photon spin-dependent directional control of energy routing.

This study explores important parameters for achieving a high-level positional control of DNA-nanoparticle hybrid structures by drop-casting onto a pre-structured silicon surface, in which the active adsorption sites were defined using electron beam lithography. By confining the adsorption sites to the scale of the DNA origami, we create multi-dimensional patterns and study the effect of diffusion and hybrid nanostructure concentration in the liquid on site occupation. We also propose a physical diffusion model that highlights the importance of surface diffusion in facilitating the adsorption of hybrid nanostructure onto active sites, particularly for two and one-dimensional adsorption sites. Our study shows prominent results of the hybrid nanostructure’s selective adsorption, indicating high adsorption efficiency and precise control over the position, as well as the spatial orientation. We anticipate similar results in related systems, both in terms of different surfaces and similar DNA structures. Overall, our findings offer promising prospects for the development of large-scale nanoarrays on micrometer-scale surfaces with nanometer precision and orientation control.

The creep mechanical properties of rock under dry-wet cycles are of great significance for studying the long-term aging stability of engineering rock and soil. In the past, there were few studies in this area, and most of the dry-wet cycle tests on rock samples did not conform to the actual stress state of the rock. In view of the shortcomings of these studies, this paper innovatively carried out the dry-wet cycle test of the rock under the continuous state of the stress field, and studied its mechanical properties. The specific method is to take carbonaceous shale as the research object, and use the soft rock shear rheological test system independently developed by our research group to carry out the shear creep test of carbonaceous shale under the action of dry-wet cycle. The test results show that the creep full-time curves of carbonaceous shale under different dry-wet cycles show a step-shaped curve shape. The dry-wet cycle has a significant effect on the deformation characteristics of carbonaceous shale. With the increase of the number of dry-wet cycles, the instantaneous strain of the rock gradually increases, the instantaneous shear modulus decreases from 596.650 MPa at 0 times to 365.199 MPa at 12 times, and the attenuation rate reaches 38.79%. The creep strain and cumulative creep strain become larger, the stress required for accelerated creep decreases from 3.29 MPa to 2.75 MPa, and the accelerated creep time in the third stage increases from 11.892 h to 5.316 h, and the creep effect is more significant. The long-term strength of carbonaceous shale decreases from 3.05 MPa to 2.49 MPa, and the decrease increases with the increase of dry-wet cycles. The more the number of dry-wet cycles, the smaller the undulation of the shear failure section of the carbonaceous shale, and the smoother the surface. The research results have important guiding significance for the long-term aging stability analysis of engineering rock and soil mass subjected to repeated dry-wet cycles.

Distinct models involving nonlinearity are mostly appreciated for illustrating intricate phenomena arise in the nature. The new (3+1)-dimensional generalized nonlinear Boiti-Leon-Manna-Pempinelli (BLMP) model describes the dynamical behaviors of nonlinear waves arise in incompressible fluid. This present effort deals with the well-known governing BLMP equation by adopting two efficient schemes, namely improved tanh and improved auxiliary equation. As a result, a variety of appropriate wave solutions are made available in different type functions. The gathered solutions are figured out to characterize their internal properties for depicting the relevant phenomena. Diverse wave profiles are noticed in 3D, 2D and contour sense after assigning parameter’s values involved in the achieved solutions. The finding results are comparably different and general due to the existing wave solutions. The employed approaches perform in a great way to construct analytic wave solutions of considered evolution equation and deserve further use in relevant research area.

Published: July 2023

The model for photodegradation with a modified rate constant that was developed and presented in previous study, was generalized for the application of ZnO-based photocatalyst in both thin film and powder form. The applicability of the model was proved on methylene blue discoloration on both types of photocatalysts. The photocatalytic reaction rate was found to be dependent on the depth of the solution in case of small depths for this photocatalyst. This correlataion was valid in both high and low transparency. In addition, the impact of the solution pH on the model pollutant decomposition rate was defined.

The integrated shear 3-point correlation function ζ
± measures the correlation between the local shear 2-point function ξ
± and the 1-point shear aperture mass in patches of the sky. Unlike other higher-order statistics, ζ
± can be efficiently measured from cosmic shear data, and it admits accurate theory predictions on a wide range of scales as a function of cosmological and baryonic feedback parameters. Here, we develop and test a likelihood analysis pipeline for cosmological constraints using ζ
±. We incorporate treatment of systematic effects from photometric redshift uncertainties, shear calibration bias and galaxy intrinsic alignments. We also develop an accurate neural-network emulator for fast theory predictions in MCMC parameter inference analyses. We test our pipeline using realistic cosmic shear maps based on N-body simulations with a DES Y3-like footprint, mask and source tomographic bins, finding unbiased parameter constraints. Relative to ξ
±-only, adding ζ
± can lead to ≈ 10-25% improvements on the constraints of parameters like As
(or σ
8) and w
0. We find no evidence in ξ
± + ζ
± constraints of a significant mitigation of the impact of systematics. We also investigate the impact of the size of the apertures where ζ
± is measured, and of the strategy to estimate the covariance matrix (N-body vs. lognormal). Our analysis solidifies the strong potential of the ζ
± statistic and puts forward a pipeline that can be readily used to improve cosmological constraints using real cosmic shear data.

In order to study the energy output characteristics of multi-component explosives mixed with aluminum powder and emulsified explosives, five groups of emulsified explosives containing aluminum with different proportions were used for underwater explosion experiments and overpressure tests in the air. The experimental data show that when the mass fraction of aluminum powder increases from 0% to 40%, the shock wave energy increases from 0.68 kJ·g-1 to 1.22 kJ·g-1, which increases by 79.41%. Bubble energy increased by 135.66% from 2.44 kJ·g-1 to 5.75 kJ·g-1; the total energy of underwater explosion increased by 123.40% from 3.12 kJ·g-1 to 6.97 kJ·g-1. The explosion overpressure in the air increased by 93.66% from 60.794 KPa to 117.734 KPa. Aluminum powder greatly increases the output level of emulsified explosives. Emulsified explosive containing aluminum has the characteristics of high working capacity and high explosive performance.
