Optical soliton solutions of the stochastic perturbed Radhakrishnan-Kundu-Lakshmanan equation via Itô Calculus
Authors: Bayram Mustafa 
Published: September 2023

Abstract
This study presents, for the first time, optical solitons of the stochastic perturbed Radhakrishnan-Kundu-Lakshmanan equation with Kerr law nonlinearity in the presence of chromatic and spatio-temporal dispersions. The stochastic form involves multiplicative white noise in the Ito sense, besides; the Kudryashov and the new Kudryashov methods are picked to analyze. The analysis of the stochastic soliton solutions of the Radhakrishnan-Kundu-Lakshmanan equation and the impact of noise on these solitons are the primary motivations for choosing both of these techniques rather than obtaining many solitons. Therefore, the first goal is to obtain the most basic soliton types, bright and dark solitons, and the second goal is to observe the white noise effect on these solitons. By applying the proposed methods, bright and dark solitons are obtained, and the noise effect on these solitons is illustrated using both 3D and 2D graphic presentations, along with necessary comments. The presentation of the examined model for the first time in this article reflects its originality in terms of contributing both the study and the obtained results to the literature.
Effect of laser-irradiation on some significant physical properties of SeTeIn glass-ceramic
Authors: Chandel N , Elsaeedy H I , Mehta N 
Published: September 2023

Abstract
Laser irradiation on the samples of electronic/optical materials is a versatile tool to modify the structural morphology without changing their composition. We have explored the micro-structural changes (e.g., crystal size, defect state density, etc) induced by the He-Ne laser in Se80Te10In10 alloy. A systematic and detailed investigation of the laser-induced effects in Se80Te10In10 alloy has been undertaken using combinations of microscopic and macroscopic probe techniques like Differential Scanning Calorimeter (DSC), x-ray diffractometer (XRD), Scanning electron microscope (SEM), Transmission electron microscope (TEM). Investigations of the structural, thermal, electrical, and spectroscopic characterization of the Se80Te10In10 alloy have been compared before and after laser exposure. The glass transition/crystallization enthalpies and dielectric constant/loss are significantly increased after laser exposure. The results of structural characterization show that exposure to laser light causes crystal growth which plays a major role in modifying other characteristics of Se80Te10In10 alloy. The comparison of the present results with the literature confirms that laser exposure is a more effective way than the compositional variation approach for tailoring the dielectric properties of the present glass-ceramic sample.

Published: September 2023

Abstract
This study aims to investigate the effects of titanium coatings on aluminum alloy’s tribological and fatigue properties. In this investigation, aluminum alloy samples were coated with 1 μm, 3 μm, and 5 μm using the vacuum arc melting method. The morphological and mechanical features of the samples were characterized with SEM, microhardness, contact nanoprofilometer, and calotest methods. The increase in coating thickness resulted in improved adhesion properties and achieved better surface hardness. Further, hard sub-surface layers on the aluminum alloy substrate increased fatigue resistance. The superior mechanical properties, such as microhardness, lower surface roughness, and good bonding at the interface, are critical factors in increasing the fatigue and wear resistance of the aluminum alloy. No traces of defects, such as microcracks and porosity, were found on the coated samples. The microhardness of the coated sample increased by 3.69 times that of the AK5M2 aluminum alloy. The fatigue lifetime of the 5 μm coated samples was increased by 21%. The wear resistance of titanium-coated samples showed better wear resistance against the steel counter body than other coated and uncoated samples.

Published: September 2023

Abstract
Multi-band (B, V and R) photometric and spectroscopic observations of six poorly studied contact binaries carried out at the Western Sydney University and Las Cumbres Observatory were analyzed using a recent version of the Wilson–Devenney code. All six were found to be of extreme low mass ratio ranging from 0.073 to 0.149. All are of F spectral class with the mass of the primary component ranging from 1.05M
☉ to 1.48M
☉. None show light curve features of enhanced choromospheric activity (O’Connel Effect) however five of the six do have significant ultraviolet excess indicating the presence of increased magnetic and chromospheric activity. Period analysis based on available survey data suggests two systems have a slowly increasing period suggesting mass transfer from the secondary to the primary, two have a slow declining period with likely mass transfer from primary to the secondary, while one shows a steady period, and one undergoing transition from a declining to increasing period suggesting possible mass transfer reversal. We also compare light curve solutions against theoretical markers of orbital stability and show that three of the six systems have mass ratios within the theoretical instability limit and may be regarded as potential merger candidates.
Adsorption Properties of Pb2+ by Ferric Hydroxide Loaded White Rot Fungi
Authors: Li Ningjie , Jiang Hong , Liu Jie , Yang Rui 
Published: September 2023

Abstract
In order to explore the environmental effect of white rot fungi in the formation process of iron hydroxide, white rot fungi loaded with iron hydroxide were used as adsorbent to study the adsorption performance of lead simulated wastewater. The results showed that the iron hydroxide products formed by the mineralization of white rot fungi significantly improved the adsorption effect of heavy metals on the fungus balls. The optimal adsorption conditions were obtained as follows: pH value of 6 at room temperature, initial lead ion concentration of 700 mg/L, adsorbent dosage of 1 g. The adsorption kinetics study shows that when the Pb2+ concentration is less than 1000 mg/L, the quasi-first-order kinetic equation can be used to fit better. When the Pb2+ concentration is 1000 mg/L, the main velocity control process is the quasi-second-order kinetic equation. SEM-EDS was used to characterize the microspheres before and after adsorption. It was found that the surface morphology of white rot fungi loaded with iron oxides changed from uneven to massive mass after adsorption of Pb2+, and the upper layer was covered with a layer of dense spherical lead particles. The different pH conditions also have an effect on the morphology of the microsphere surface, which will make its surface form into clusters of columns.
The Quasi-Phase Matching of Airy Beam
Authors: Zhang Hongwei , Lin Haibo , Wang Jinbao , Yang Jianxi 
Published: September 2023

Abstract
We demonstrate the Airy beam, propagating through a periodically poled nonlinear crystal, could significantly increase the conversion efficiency during the quasi-phase-matched (QPM) process. Meanwhile, the so-called co-Airy beams can be signed as a conjunction of two Airy beams by binding their collinear lateral lobes with appropriate parameters. With the help of the phase-matched modulation, the two Airy beams are united and compressed by the parameters. The set of parameters determines the direction of the “force” that the structure distribution of the co-Airy beams be pressed. We hope that our work will contribute to the generation of multi-Airy beams and further enhancement of research on Airy beam control using quasi-phase-matched crystals.
Research on Source Load Interaction Mode Supporting New Power System
Authors: Xue Yiming , Wang Jie , Sun Beibei , Chen Siqi , Ma Runpeng 
Published: September 2023

Abstract
The construction of a new power system will face challenges such as a high proportion of new energy consumption and a sustainable and reliable power supply. It is urgent to fully tap the potential of demand-side regulation, make up for the shortage of flexible regulation resources of the source side caused by a high proportion of new energy connected to the grid, and promote the transformation of power system operation to the mode of “source load interaction.” One of the effective ways to solve the above problem is to introduce a Hierarchical Load Response Center (HLRC) and establish a load regulation market, effectively promoting user participation in load regulation through market-oriented means. In this paper, the operation framework of “Dispatching Center + Trading Center + Hierarchical Load Response Center” is proposed to support the interaction of source and load under the new power system and the coordination and cooperation relationship of LRC in the operation of the load control market is analyzed. Based on this, the source load interaction mode led by HLRC is analyzed, and the source load interaction modes in the primary and secondary markets are proposed, respectively.

Published: September 2023

Abstract
The thermal link between the second stage of cryocooler and
the superconducting magnet has a significant influence on the
initial cooldown time of conduction-cooled superconducting
magnet. In this paper, a numerical investigation is carried out on
the initial cooldown characteristics of a superconducting magnet
system used flexible copper strap as the thermal link. The optimal
shape ratio (cross-sectional area to length) of the copper strap is
obtained to minimize the cooldown time. The results show that
optimal shape ratio decreases with increasing the length. In
addition, the effect of copper purity on the cooldown time is little
at the optimal shape ratio or at RRR (Residual Resistive Ratio) >
100.

Published: September 2023

Abstract
Research reactors are strong and stable neutrons sources,
and various researches and applications were carried out using their
neutron and gamma beamlines. Some research reactors, such as
Miniature Neutron Source (MNSR) Reactors, do not have beam tube in
their original design, which can be considered as a
disadvantage. The design and installation of beamlines can develop
their applications. In this research, the design and optimization of
a suitable neutron beamline for PGNAA is done at Isfahan
MNSR. Designs are done to reach the appropriate neutron beam
parameters and taking into account the geometrical limitations of
the MNSR. Neutron beam parameters including thermal neutron flux,
thermal to total neutron flux, and thermal neutron flux to gamma
dose ratio are considered. For this, vertical beamlines with
different diameters are simulated and the optimal diameter is
determined. Also, for optimization of beam parameters, a thermal
column and gamma filter are considered and optimal conditions are
determined.
A techno-economic assessment on biomass waste-to-energy potential in Cameroon
Authors: Longfor Nkweauseh Reginald , Dong Liang , Wang Jian , Qian Xuepeng 
Published: September 2023

Abstract
Biomass waste-to-energy (WtE) offers a critical solution to carbon neutrality through improving the resource recycling and recovery. This study comprehensively assessed how WtE can be implemented in generating electricity for Cameroon with an estimation to the energy potential of anaerobic digestion of three organic waste streams including municipal solid waste, wastewater sludge, and livestock manure. We assessed the energy potential in terms of the theoretical, technical, and economic potentials. The findings highlighted a theoretical energy potential of 936.37 TWh yr−1 in Cameroon. If only applied to a fraction of organic wastes, the technical potential could reach 48.64 TWh yr−1. Furthermore, considering the economic costs of technology installation, 17.06 TWh yr−1 could be generated, and this economic generation potential could supply to 38.9% of the country’s current electricity demand. This study implies that WtE would significantly reduce fossil fuels consumption and greenhouse gases emissions from poorly disposed wastes, to enable decarbonization transition and improve human health in African countries.
Entanglement capacity of fermionic Gaussian states
Authors: Huang Youyi , Wei Lu 
Published: September 2023

Abstract
We study the capacity of entanglement as an alternative to entanglement entropies in estimating the degree of entanglement of quantum bipartite systems over fermionic Gaussian states. In particular, we derive the exact and asymptotic formulas of average capacity of two different cases—with and without particle number constraints. For the later case, the obtained formulas generalize some partial results of average capacity in the literature. The key ingredient in deriving the results is a set of new tools for simplifying finite summations developed very recently in the study of entanglement entropy of fermionic Gaussian states.
Godbillon-Vey invariants of Non-Lorentzian spacetimes and Aristotelian hydrodynamics
Authors: Marotta Vincenzo Emilio , Szabo Richard J 
Published: September 2023

Abstract
We study the geometry of foliated non-Lorentzian spacetimes in terms of the Godbillon-Vey class of the foliation. We relate the intrinsic torsion of a foliated Aristotelian manifold to its Godbillon-Vey class, and interpret it as a measure of the local spin of the spatial leaves in the time direction. With this characterisation, the Godbillon-Vey class is an obstruction to integrability of the

G

-structure defining the Aristotelian spacetime. We use these notions to formulate a new geometric approach to hydrodynamics of fluid flows by endowing them with Aristotelian structures. We establish conditions under which the Godbillon-Vey class represents an obstruction to steady flow of the fluid and prove new conservation laws.
Entanglement witnessing with untrusted detectors
Authors: Viola Giuseppe , Miklin Nikolai , Gachechiladze Mariami , Pawłowski Marcin 
Published: September 2023

Abstract
We consider the problem of entanglement detection in the presence of faulty, potentially malicious detectors. A common—and, as of yet, the only—approach to this problem is to perform a Bell test in order to identify nonlocality of the measured entangled state. However, there are two significant drawbacks in this approach: the requirement to exceed a critical, and often high, detection efficiency, and much lower noise tolerance. In this paper, we propose an alternative approach to this problem, which is resilient to the detection loophole and is based on the standard tool of entanglement witness. We discuss how the two main techniques to detection losses, namely the discard and assignment strategies, apply to entanglement witnessing. We demonstrate using the example of a two-qubit Bell state that the critical detection efficiency can be significantly reduced compared to the Bell test approach.
Work fluctuations for a confined Brownian particle: the role of initial conditions
Authors: Carollo Giovanni Battista , Semeraro Massimiliano , Gonnella Giuseppe , Zamparo Marco 
Published: September 2023

Abstract
We study the large fluctuations of the work injected by the random force into a Brownian particle under the action of a confining harmonic potential. In particular, we compute analytically the rate function for generic uncorrelated initial conditions, showing that, depending on the initial spread, it can exhibit no, one, or two singularities associated to the onset of linear tails. A dependence on the potential strength is observed for large initial spreads (entailing two singularities), which is lost for stationary initial conditions (giving one singularity) and concentrated initial values (no singularity). We discuss the mechanism responsible for the singularities of the rate function, identifying it as a big jump in the initial values. Analytical results are corroborated by numerical simulations.
Revised gas-phase formation network of methyl cyanide: the origin of methyl cyanide and methanol abundance correlation in hot corinos
Authors: Giani Lisa , Ceccarelli Cecilia , Mancini Luca , Bianchi Eleonora , Pirani Fernando , Rosi Marzio , Balucani Nadia 
Published: September 2023

ABSTRACT
Methyl cyanide (CH3CN) is one of the most abundant and widely spread interstellar complex organic molecules (iCOMs). Several studies found that, in hot corinos, methyl cyanide and methanol abundances are correlated suggesting a chemical link, often interpreted as a synthesis of them on the interstellar grain surfaces. In this article, we present a revised network of the reactions forming methyl cyanide in the gas phase. We carried out an exhaustive review of the gas-phase CH3CN formation routes, propose two new reactions, and performed new quantum mechanics calculations of several reactions. We found that 13 of the 15 reactions reported in the databases KIDA and UDfA have incorrect products and/or rate constants. The new corrected reaction network contains 10 reactions leading to methyl cyanide. We tested the relative importance of those reactions in forming CH3CN using our astrochemical model. We confirm that the radiative association of CH3+ and HCN, forming CH3CNH+, followed by the electron recombination of CH3CNH+, is the most important CH3CN formation route in both cold and warm environments, notwithstanding that we significantly corrected the rate constants and products of both reactions. The two newly proposed reactions play an important role in warm environments. Finally, we found a very good agreement between the CH3CN predicted abundances with those measured in cold (∼10 K) and warm (∼90 K) objects. Unexpectedly, we also found a chemical link between methanol and methyl cyanide via the CH$_{3}^{+}$ ion, which can explain the observed correlation between the CH3OH and CH3CN abundances measured in hot corinos.

Published: September 2023

Abstract

Introduction
Members of dual-smoker couples (in which both partners smoke) are unlikely to try to quit smoking and are likely to relapse if they do make an attempt. The purpose of this study was to investigate the feasibility, tolerability, and preliminary outcomes of dyadic adaptations of financial incentive treatments (FITs) to promote smoking cessation in dual-smoker couples.

Aims and Methods
We enrolled 95 dual-smoker couples (N = 190) in a three-arm feasibility RCT comparing two partner-involved FITs (single vs. dual incentives) against a no-treatment control condition. Participants in all conditions were offered nicotine replacement and psychoeducation. A 3-month follow-up provided information about retention, tolerability (ie, self-reported benefits and costs of the study), and preliminary efficacy (ie, program completion, quit attempts, point-prevalent abstinence, and joint quitting).

Results
Results suggest dyadic adaptations were feasible to implement (89% retention rate) and highly tolerable for participants (p &lt; .001). Neither feasibility nor tolerability varied across the treatment arm. Preliminary efficacy outcomes indicated partner-involved FITs have promise for increasing smoking cessation in dual-smoker couples (OR = 2.36–13.06).

Conclusions
Dyadic implementations of FITs are feasible to implement and tolerable to participants.

Implications
The evidence that dyadic adaptations of FITs were feasible and tolerable, and the positive preliminary efficacy outcomes suggest that adequately powered RCTs formally evaluating the efficacy of dyadic adaptations of FITs for dual-smoker couples are warranted.

AbstractTrichinellosis caused by Trichinella spiralis (T. spiralis) is a major food‐borne parasitic zoonosis worldwide. Prevention of trichinellosis is an effective strategy to improve patient quality of life. Macrophage migration inhibitory factor (MIF) is closely related to the occurrence and development of several parasitic diseases. Studying the impact of MIF deficiency (Mif−/−) on the alterations in host fecal microbiota due to T. spiralis infection may contribute to proposing a novel dual therapeutic approach for trichinellosis. To reveal the diversity and differences in fecal microbial composition, feces were collected from T. spiralis‐uninfected and T. spiralis‐infected wild‐type (WT) and MIF knockout (KO) C57BL/6 mice at 0, 7, 14, and 35 days post‐infection (dpi), and the samples were sent for 16S rRNA amplicon sequencing on the Illumina NovaSeq platform. Flow cytometry was used to determine the expression levels of IFN‐γ and IL‐4 in the CD4+/CD8+ T‐cell sets of mouse spleens. The results showed that operational taxonomic unit (OTU) clustering, relative abundance of microbial composition, alpha diversity, and beta diversity exhibited significant changes among the eight groups. The LEfSe analysis selected several potential biomarkers at the genus or species level, including Akkermansia muciniphila, Lactobacillus murinus, Coprococcus catus, Firmicutes bacterium M10_2, Parabacteroides sp. CT06, and Bacteroides between the KTs and WTs groups. The predicted bacterial functions of the fecal microbiota were mainly involved in metabolism, such as the metabolism of carbohydrates, amino acids, energy, cofactors, vitamins, nucleotides, glycans, and lipids. Flow cytometry revealed an increased CD3+CD8−/CD3+CD8+ T‐cell ratio and increased IFN‐γ and IL‐4 levels in CD3+CD8− T‐cell sets from WT and MIF KO mice at 7 dpi. The results indicated that both MIF KO and infection time have a significant influence on the CD3+CD8−IFN‐γ+ and CD3+CD8−IL‐4+ response in mice after T. spiralis. In conclusion, this research showed alterations of the fecal microbiota and immune response in both WT and MIF KO mice before and after T. spiralis infection. These results revealed a potential role of MIF in regulating the pathogenesis of trichinellosis related to the intestinal microbiota. Importantly, the selected potential biomarkers combined with MIF will also offer a novel therapeutic approach to treat trichinellosis in the future.
Existential Care in Daily Nursing Practice

Published: September 2023

ABSTRACT:
Relationship-centered palliative nursing during serious illness requires existential care. Yet, multilevel systemic barriers hinder nurses' ability to provide this care. The authors suggest ways to navigate these barriers, highlighting existential care priorities that nurses can attend to in their daily practice. These include 1) maintaining a strengths-based orientation, 2) taking a life course perspective, 3) grounding care firmly in relationships, and 4) responding moment to moment. They propose that by emphasizing existential care in palliative nursing, we can create a more compassionate and human-centered health system.
