Authors: Xu Taolong , Wang Wei , Jiang Hongye , He Gongzhen 
Published: November 2022

AbstractThe deformation and failure characteristics of pipeline steel depend on its atomic structure and microstructure. Based on the serial multi-scale analysis technology, the ferrite/cementite (α-Fe/Fe3C) lamellar atomic structure with Bagaryatskii orientation relationship is established. In order to obtain the experimental sample of the lowest energy state, The step-by-step relaxation method of conjugate gradient energy minimization and constant temperature and constant pressure relaxation under NPT conditions is carried out, and the energy state and atomic structure of the relaxed samples are analyzed. For the models of different cementite terminal plane structures, the tension displacement curves on the propagation path of mode I central through crack are extracted respectively, combined with the bilinear cohesion zone model, The cohesion parameters at the atomic scale are successfully transferred from bottom to top to the macro and micro scales. By simulating the reaction force and displacement response law at the loading point, the critical fracture toughness of each terminal interface of ferrite–pearlite pipeline steel at different scales is calculated, which provides a reliable path for exploring the micro mechanism of macro cracking behavior of pipeline steel.

AbstractIt is well known that repeated projective measurements can either slow down (the Zeno effect) or speed up (the anti-Zeno effect) quantum evolution. Until now, studies of these effects for a two-level system interacting with its environment have focused on repeatedly preparing the excited state via projective measurements. In this paper, we consider the repeated preparation of an arbitrary state of a two-level system that is interacting strongly with an environment of harmonic oscillators. To handle the strong interaction, we perform a polaron transformation and then use a perturbative approach to calculate the decay rates for the system. Upon calculating the decay rates, we discover that there is a transition in their qualitative behaviors as the state being repeatedly prepared continuously moves away from the excited state and toward a uniform superposition of the ground and excited states. Our results should be useful for the quantum control of a two-level system interacting with its environment.

Abstract
Cardiac hypertrophy is necessary for the heart to accommodate an increase in workload. Physiological, compensated hypertrophy (e.g. with exercise) is reversible and largely due to cardiomyocyte hypertrophy. Pathological hypertrophy (e.g. with hypertension) is associated with additional features including increased fibrosis and can lead to heart failure. RAF kinases (ARAF/BRAF/RAF1) integrate signals into the extracellular signal-regulated kinase 1/2 cascade, a pathway implicated in cardiac hypertrophy, and activation of BRAF in cardiomyocytes promotes compensated hypertrophy. Here, we used mice with tamoxifen-inducible cardiomyocyte-specific BRAF knockout (CM-BRAFKO) to assess the role of BRAF in hypertension-associated cardiac hypertrophy induced by angiotensin II (AngII; 0.8 mg/kg/d, 7 d) and physiological hypertrophy induced by phenylephrine (40 mg/kg/d, 7 d). Cardiac dimensions/functions were measured by echocardiography with histological assessment of cellular changes. AngII promoted cardiomyocyte hypertrophy and increased fibrosis within the myocardium (interstitial) and around the arterioles (perivascular) in male mice; cardiomyocyte hypertrophy and interstitial (but not perivascular) fibrosis were inhibited in mice with CM-BRAFKO. Phenylephrine had a limited effect on fibrosis but promoted cardiomyocyte hypertrophy and increased contractility in male mice; cardiomyocyte hypertrophy was unaffected in mice with CM-BRAFKO, but the increase in contractility was suppressed and fibrosis increased. Phenylephrine induced a modest hypertrophic response in female mice and, in contrast with the males, tamoxifen-induced loss of cardiomyocyte BRAF reduced cardiomyocyte size, had no effect on fibrosis and increased contractility. The data identify BRAF as a key signalling intermediate in both physiological and pathological hypertrophy in male mice, and highlight the need for independent assessment of gene function in females.
Extra‐large MIMO enabling slow fluid antenna massive access for millimeter‐wave bands
Authors: Wong Kai‐Kit , Tong Kin‐Fai , Chen Yu , Zhang Yangyang 
Published: November 2022

AbstractFluid antenna multiple access (FAMA) is a new way of accommodating a large number of users on a single channel for massive connectivity, with slow FAMA (s‐FAMA) being the practical version for achieving this. The impressive performance is understood to be achievable if the users have independent Rayleigh fading envelopes. With mobile networks vamping up the operating frequencies in 5G and beyond, nevertheless, the channel will have less multipath and become more directional. It is unclear if s‐FAMA still performs well and how its performance is affected by different channel parameters. To address this, this letter first develops a multipath fading channel model capable of modelling a mixture of directional line‐of‐sight (LoS) and non‐LoS paths over the ports of a fluid antenna system. The results indicate that a large number of paths in the channel is essential to the performance and a large Rice factor will degrade the performance rapidly. Also, contrast to the initial belief, the size of the fluid antenna plays a more important role than the number of ports or resolution of the fluid antenna. To restore the gain of s‐FAMA, it is proposed to employ extra‐large multiple‐input multiple‐output (XL‐MIMO) at the base station (BS) to scramble the channel and create artificial multipath so that the users' envelopes can become independent Rayleigh again. The results confirm that XL‐MIMO enabling s‐FAMA is an effective technique for massive connectivity in the directional millimeter‐wave (mmWave) bands.

Context. Substituted methanimines and ethylenes have been identified in the interstellar medium. Therefore, allylimine (CH2 =CH–CH=NH) represents a promising candidate for a new interstellar detection.
Aims. The goal of the present work is to perform a comprehensive laboratory investigation of the rotational spectrum of allylimine in its ground vibrational state in order to obtain a highly precise set of rest frequencies to assist its search for astronomical sources.
Methods. The rotational spectra of the two most stable trans–anti and trans–syn geometrical isomers of allylimine were recorded in the laboratory in the 84–300 GHz frequency interval. Measurements were performed using a source-modulation millimetre-wave spectrometer equipped with a pyrolysis system for the production of unstable species. High-level ab initio calculations were performed to assist the analysis and to obtain reliable estimates for an extended set of spectroscopic parameters. Guided by new laboratory data, allylimine was searched for in space using a sensitive spectral survey of the G+0.693-0.027 molecular cloud, located at the Galactic centre.
Results. Almost 1000 rotational transitions have been recorded for trans–anti and trans–syn allylimine. These new data have enabled the determination of a very accurate set of spectroscopic parameters including rotational, quartic and sextic centrifugal distortion con-stants, as well as nuclear quadrupole coupling constants. The improved spectral data allowed us to report a tentative detection for both allylimine isomers in the G+0.693-0.027 molecular cloud, located at the Galactic centre.

Published: November 2022

Multiple technical and biological systems exhibit multiphase flow phenomena. The demands for accurate calculations of the physical phenomena that occur in engineering technologies have increased along with their rapid advancement. However, it is very hard to identify two- and multi-phase flow through experimental measurements, as a result, in addition to experimental measurements, numerical simulations are also performed, which can help improve our physical understanding of the complex phenomenon of phase transformations. The goal of numerical simulations of phase changes is to precisely simulate the real progress and experiment. These simulations operate on the basis of physical principles and correlation coefficients of phase changes. These correlation coefficients have a different range of values. The examination of the Lee model's correlation coefficients from the ANSYS Fluent environment, which is now the most popular for multiphase flow simulations, is the subject of the article that is being given. In this article is also described and tested the numerical simulation of interphase mass transport in a closed space.
Research background: The article is focused on the problematics of multiphase flows. In ANSYS Fluent, there are many types of models, which are used for the numerical simulations of this phenomena. In models are included correlation parameters, which are specific for every single situation and are within the given ranges. This paper is about the Lee model, which correlation coefficients are in the range from 10-3 to 102.
Purpose of the article: A detailed description of Lee's model with its testing on a heat pipe in the ANSYS Fluent program with determined correlation coefficients.
Methods: The use of CFD simulation of multiphase flow to determine correlation coefficients.
Findings & Value added: Testing the correlation coefficients of Lee's model and finding their appropriate values for the given situation.

Published: November 2022

This paper presents the results of the drag coefficient estimations for different types of NREL airfoils based on the experimental data. Namely, it was S803, S807, S813, and S817 profiles with the same chord length. The investigations were conducted at three angles of attack α=0°, α=±5°, different chord-based Reynolds numbers 0.6×105, 1.3×105 and 2.6×105. While, measuring cross-sections were placed behind the trailing edge at x∙c−1≈0.2, 0.4 and 1.0. Experimental data were collected using a hot-wire split fiber probe 55R55, which allowed us to estimate the characteristics of turbulent flow in stream-wise and crosswise directions. According to the obtained results, the highest and lowest Cd values correspond to profiles S817 and S803, respectively. Moreover, the results show that more asymmetric profiles S803 and S807 have the lowest resistance at zero angles of attack.
Research background: Application of Antonia and Rajagopalan methodology to drag assessment of various stream bodies.
Purpose of the article: Comparative evaluation of the drag coefficients of the NREL airfoils based on instantaneous velocity distribution behind.
Methods: Hot-wire anemometry with split fiber probe 55R55.
Findings & Value added: The highest drag coefficient corresponds to the S817 profile. The asymmetry of the airfoil shape has a significant impact on its drag characteristics.
Expanding the PIV Spectral Range and the Turbulence Generated by Grid of Prismatic Circular Cylinders
Authors: Duda Daniel , Yanovych Vitalii , Uruba Václav 
Published: November 2022

The grid turbulence past a grid made of row of prismatic circular rods (rod diameter = 10 mm, rod spacing = 20 mm) perpendicular to the flow is observed by using a pair of PIV cameras. The first one has field of view larger (81 mm), the second one smaller (31 mm), which increases the dynamical range, where the spectral turbulence properties can be explored. Energy spectra displays usual behavior approximately following k −5/3 law, the anisotropy originates at larger scales and the flatness describing strong rare events is connected with smaller scales. The spectral properties of vorticity do not collapse due to the different lengthscale of differentiation, which make questionable the previous research based on the vorticity statistics.
Research background: Grid turbulence is the best experimentally accessible prototype of ideal homogenous and isotropic turbulence, although it is known, it is not exactly the ideal one.
Purpose of the article: This contribution explores the possibility of expanding the limited dynamical range of PIV method.
Methods: Particle Image Velocimetry is based on observing the motion of small particles carried by the flow.
Findings & Value added: Anisotropy connected with large scales, flatness with small scales; it does not work for vorticity.

Abstract
Purpose This guideline aims to summarize the current state of knowledge about vaginal birth at term. The guideline focuses on definitions of the physiological stages of labor as well
as differentiating between various pathological developments and conditions. It also assesses the need for intervention and the options to avoid interventions. The second part of this
guideline presents recommendations and statements on care during the dilation and expulsion stages as well as during the placental/postnatal stage.
Methods The German recommendations largely reproduce the recommendations of the National Institute for Health and Care Excellence (NICE) CG190 guideline “Intrapartum care for healthy
women and babies”. Other international guidelines were also consulted in individual cases when compiling this guideline. In addition, a systematic search and analysis of the literature was
carried out using PICO questions where necessary, and other systematic reviews and individual studies were taken into account. For easier comprehension, the assessment tools of the Scottish
Intercollegiate Guidelines Network (SIGN) were used to evaluate the quality of additionally consulted studies. Otherwise, the GRADE system was used for the NICE guideline, and the evidence
reports of the IQWiG were used to evaluate the quality of the evidence.
Recommendations Recommendations and statements were formulated based on identified evidence and/or a structured consensus.

AbstractThis study aimed to investigate the immediate effects of acute bout of aerobic
exercise on arterial stiffness in individuals with different smoking statuses. A
total of 940 male individuals (mean age of 36.82±7.76 years) in the
Kailuan study cohort were selected to participate in the fifth National Physical
Fitness Monitoring. All participants completed measurements of brachial
– ankle pulse wave velocity (baPWV) before and after twice-quantitative
cycle ergometer exercise. Four groups were defined: (1) non-smokers
(n=231), (2) former smokers (n=165), (3) light smokers
(1–10 cigarettes/day, n=254), (4) heavy smokers
(>10 cigarettes/day, n=290). Generalized linear models
were established to analyze between-group differences in the change in baPWV
before and after acute aerobic exercise in individuals with different smoking
statuses. Overall, after acute aerobic exercise, baPWV was immediately decreased
significantly (−33.55 cm/s [95% CI,
− 39.69 to −27.42]). Compared with non-smokers, former
smokers, light smokers, and heavy smokers showed a greater decrease in baPWV
(−12.17 cm/s [95%CI, − 30.08 to
5.75], − 18.43 cm/s [95%CI,
−34.69 to − 2.16], and
−22.46 cm/s [95%CI, − 38.39 to
− 6.54]) respectively. There is a transient decrease in baPWV in
individuals with different smoking statuses. Compared with non-smokers, baPWV
decreased more significantly in light and heavy smokers.

Multiple Disabilities: Preventability and Potential Cost Savings by Therapeutic
Drug Monitoring

Published: November 2022

Abstract
Introduction Children and adolescents with multiple disabilities and
mental disorders (CAMD) are frequently treated with antipsychotic drugs.
However, CAMD are particularly susceptible to serious adverse drug reactions
(sADRs). This retrospective study examined the frequency of sADRs to
antipsychotics in CAMD. Further, the potential preventability of these sADRs
through therapeutic drug monitoring (TDM) and the potential socio-economic
benefits of TDM were explored.
Methods Routine clinical data of all patients treated at a specialized
psychiatric clinic for CAMD between January 2017 and December 2018 were
retrospectively examined. Data on the occurrence of sADRs (definition according
to the European Medicines Agency), their causality with antipsychotics, as well
as their preventability (Schumock criteria) were extracted from patient files.
The prolongation of the hospital stay due to sADRs was calculated, and the cost
savings were estimated if TDM had been applied. The data were based on a
subsample of the KiDSafe project, supported by the Innovation Fund of the Joint
Federal Committee, grant number 01NVF16021.
Results One hundred two CAMD who were administered at least one
antipsychotic drug during inpatient treatment were identified. Of these
patients, 22 (21.6%) sADRs with a possible causal relationship with the
antipsychotic treatment were documented. Eleven sADRs (50%) could
potentially have been prevented through TDM. Mitigating sADRs through TDM likely
would have prevented prolonged hospital stays and thus conferred considerable
savings for health insurance companies.
Discussion The routine implementation of TDM is urgently recommended for
antipsychotic treatment in CAMD to increase drug therapy safety.

AbstractThis century has been proclaimed the Asian century, as industrialised countries such as Japan, Singapore, and South Korea, along with rapidly emerging nations such China and India, have contributed to worldwide economic growth. In response, research has analysed the reasons why Asian business and management have found such success. Based on a bibliometric analysis ofAsian Business & Management(ABM), a premier journal devoted to Asian management, here we examine the performance of the research constituents, social structure, and intellectual structure of 331 scholarly papers, which sheds light on the growing influence of ABM through six major knowledge clusters: corporate social responsibility; business management in emerging markets; corporate governance; internationalization; political and business ties; and organization culture and performance. Temporal analysis reveals the emergence of strategy and human resource management as a distinct knowledge cluster and the increasing importance of China as a research context and producer. Based on this analysis, we propose future research directions.
3D Monte-Carlo model to study the transport of hot electrons in the context of inertial confinement fusion. Part II
Authors: Tentori A. , Colaïtis A. , Batani D. 
Published: November 2022

We describe two numerical investigations performed using a 3D plasma Monte-Carlo code, developed to study hot-electron transport in the context of inertial confinement fusion. The code simulates the propagation of hot electrons in ionized targets, using appropriate scattering differential cross sections with free plasma electrons and ionized or partially ionized atoms. In this paper, we show that a target in the plasma state stops and diffuses electrons more effectively than a cold target (i.e., a target under standard conditions in which ionization is absent). This is related to the fact that in a plasma, the nuclear potential of plasma nuclei has a greater range than in the cold case, where the screening distance is determined by the electronic structure of atoms. However, in the ablation zone created by laser interaction, electrons undergo less severe scattering, counterbalancing the enhanced diffusion that occurs in the bulk. We also show that hard collisions, i.e., collisions with large polar scattering angle, play a primary role in electron beam diffusion and should not be neglected. An application of the plasma Monte-Carlo model to typical shock ignition implosions suggests that hot electrons will not give rise to any preheating concerns if their Maxwellian temperature is lower than 25–30 keV, although the presence of populations at higher temperatures must be suppressed. This result does not depend strongly on the initial angular divergence of the electron beam set in the simulations.
