Sociality and moral conflicts
Authors: Márquez Reiter Rosina , Kádár Dániel Z. 
Published: March 2022

Abstract
This paper explores how understandings of sociality influence the way members of two different social groups
discursively animate moral conflicts. It examines how moral conflicts are constructed in life-story interviews by Chinese and
Latin American migrants as they reflect on patterns of sociation with co-ethnics in London. These interviews typify the kind of
conflicts that emerged across a 102 interview database where a discrepancy between expectations of how contextually-situated
interpersonal relations are established and how they should unfold are. The transnational setting that we focus on inevitably
draws our attention to the importance of the larger relational context where interpersonal relations among migrant co-ethnics are
entrenched. In this context, rights and obligations towards one another are often reconfigured to adapt to the circumstances of
the new environment. This paper turns the pragmatic lens on transcultural relations.

Authors: Habib Sandy 
Published: March 2022

Abstract
The aim of this paper is to describe five speech practices employed by Jish Arabic speakers: greeting a passerby,
forms of address, necessary expressions when talking about death, necessary expressions when praising someone, and necessary
expressions when mentioning entities of “low” value. These five speech practices are described using the Cultural Scripts
Approach, which employs simple, universal language, thus enhancing descriptive accuracy and reducing ethnocentrism.
Objects of remembrance and renewal

Published: March 2022

AbstractThe relation between translation and experiences of migrants as depicted in fiction has been widely discussed, through the lens of both interlingual translation and cultural translation. The latter refers to the ongoing negotiation and representation of one’s values, symbols, and practices vis-à-vis the local majority group. The link between cultural translation and interlingual translation deserves careful exploration. This article examines the interface between these translational concepts through their intersections with two material diasporic objects in Chitra Banerjee Divakaruni’sQueen of Dreams. The first object is the dream journals, handwritten in Bengali by the late mother of the young protagonist and translated into English by her father. The second object comprises culinary items and the interlingual procedures related to them. The analysis showcases various ways in which interlingual translation may provoke and participate in cultural translation within the context of diasporic literature.
Arthrogenic muscle inhibition manifests in thigh musculature motor unit characteristics after anterior cruciate ligament injury
Authors: Schilaty Nathan D. , McPherson April L. , Nagai Takashi , Bates Nathaniel A. 
Published: March 2022

ABSTRACTJoint trauma induces a presynaptic reflex inhibition termed arthrogenic muscle inhibition (AMI) that prevents complete activation of muscles. Reduced motor unit (MU) output is a hypothesised mechanism for persistent strength deficits. The objective of this study was to determine MU characteristics of thigh musculature and determine how they change with anterior cruciate ligament (ACL) injury compared to healthy controls. A randomised protocol of knee flexion/extension isometric contractions (10–50% maximal voluntary isometric contraction) was performed for each leg with surface EMG 5‐pin array electrodes placed on the vastus medialis, vastus lateralis, semitendinosus and biceps femoris. Longitudinal assessments for average rate coding, recruitment thresholds and MU action potentials were acquired at 6‐month intervals. With exception of the vastus medialis, all thigh musculature of ACL‐injured demonstrated smaller MU action potential peak‐to‐peak amplitude. For average rate coding, ACL‐injured demonstrated lower coding rates than Controls for the quadriceps (p < .05) and higher rates than Controls for the hamstrings (p < .05). These MU characteristics were different from Controls after ACL reconstruction up to 12 months post‐surgery, yet maximal strength increased during this time frame. As thigh MU characteristics are known across phases of ACL rehabilitation, future studies can assess these patterns of motor control and their potential to determine risk of re‐injury. Further, future rehabilitation can target specific intervention programmes to restore motor control.Highlights
Motor unit strategies of arthrogenic muscle inhibition are characterised for the first time via decomposed EMG.
Motor unit deficits of thigh musculature persist throughout all phases of ACL rehabilitation, even after return‐to‐sport.
After ACL injury, motor unit sizes at similar recruitment thresholds were smaller than those of healthy controls.
Mumford–Shah regularization in electrical impedance tomography with complete electrode model
Authors: Jauhiainen Jyrki , Seppänen Aku , Valkonen Tuomo 
Published: March 2022

Abstract
In electrical impedance tomography (EIT), we aim to solve the conductivity within a target body through electrical measurements made on the surface of the target. This inverse conductivity problem is severely ill-posed, especially in real applications with only partial boundary data available. Thus regularization has to be introduced. Conventionally regularization promoting smooth features is used, however, the Mumford–Shah (M–S) regularizer familiar for image segmentation is more appropriate for targets consisting of several distinct objects or materials. It is, however, numerically challenging. We show theoretically through Γ-convergence that a modification of the Ambrosio–Tortorelli approximation of the M–S regularizer is applicable to EIT, in particular the complete electrode model of boundary measurements. With numerical and experimental studies, we confirm that this functional works in practice and produces higher quality results than typical regularizations employed in EIT when the conductivity of the target consists of distinct smoothly-varying regions.

Abstract
Aqueous Zn-iodine redox flow batteries have aroused great interest for the features of high capacity, excellent stability, low cost, and high safety, yet the dissatisfying energy efficiency still limits their future advancement. In this work, three-dimensional semiconductor BiVO4 nanoparticles decorated hierarchical TiO2/SnO2 arrays (BiVO4@TiO2/SnO2) were applied as photocathode in Zn-iodine redox flow batteries (ZIRFBs) for the realization of efficient photo-assisted charge/discharge process. The photogenerated carriers at the solid/liquid interfaces boosted the oxidation process of I−, and thus contributed to a significant elevation in energy efficiency of 14.9% (@0.5 mA cm−2). A volumetric discharge capacity was extended by 79.6% under light illumination, owing to a reduced polarization. The photocathode also exhibited an excellent durability, leading to a stable operation for over 80 h with a maintained high energy efficiency of ∼90% @0.2 mA cm−2. The research offers a feasible approach for the realization of high-energy-efficiency aqueous Zn-iodine batteries towards high-efficiency energy conversion and utilization.

Abstract
Herein, an amphiphilic block copolymer CD44-targeting peptide-conjugated polyethylene glycol-block-hydroxyethyl starch-block-poly (L-lactic acid) (CD44p-conjugated PEG-b-HES-b-PLA) are synthesized, which could self-assemble into the pH-responsive and CD44-targeting polymer micelles against breast cancer cells MDA-MB-231. Emodin (Emo) is a natural anthraquino with pharmacological activities in anti-tumor effects. However, Emo suffers from poor water solubility, low biocompatibility, rapid systemic elimination, and off-target side effects, resulting in unsatisfactory treatment outcomes. Nanotechnology-based drug delivery systems have proven great potential for cancer chemotherapy. The constructed polymeric micelles Emo@CD44p-PM have exhibited an average size of 154.5 ± 0.9 nm characterized by DLS and TEM. Further, the Emo@CD44p-PM have effective Emo-loading capacity, good thermal stability, and pH responsiveness. Intracellular uptake study shows the enhanced cellular internalization of Emo@CD44p-PM due to the increased exposure of CD44p enhances the cellular internalization of Emo@CD44p-PM effectively. Furthermore, the in vitro results showed Emo@CD44p-PM has been observed good biocompatibility and anti-tumor effects. Therefore, the polymeric micelles Emo@CD44p-PM provide a promising delivery strategy of targeted therapy for breast cancer.
Simple beam hardening correction method (2DCalBH) based on 2D linearization

Published: March 2022

Abstract

Objective. The polychromatic nature of the x-ray spectrum in computed tomography leads to two types of artifacts in the reconstructed image: cupping in homogeneous areas and dark bands between dense parts, such as bones. This fact, together with the energy dependence of the mass attenuation coefficients of the tissues, results in erroneous values in the reconstructed image. Many post-processing correction schemes previously proposed require either knowledge of the x-ray spectrum or the heuristic selection of some parameters that have been shown to be suboptimal for correcting different slices in heterogeneous studies. In this study, we propose and validate a method to correct the beam hardening artifacts that avoids such restrictions and restores the quantitative character of the image. Approach. Our approach extends the idea of the water-linearization method. It uses a simple calibration phantom to characterize the attenuation for different soft tissue and bone combinations of the x-ray source polychromatic beam. The correction is based on the bone thickness traversed, obtained from a preliminary reconstruction. We evaluate the proposed method with simulations and real data using a phantom composed of PMMA and aluminum 6082 as materials equivalent to water and bone. Main results. Evaluation with simulated data showed a correction of the artifacts and a recovery of monochromatic values similar to that of the post-processing techniques used for comparison, while it outperformed them on real data. Significance. The proposed method corrects beam hardening artifacts and restores monochromatic attenuation values with no need of spectrum knowledge or heuristic parameter tuning, based on the previous acquisition of a very simple calibration phantom.
Gas sensing performances of commercial carbon fibers functionalized by NiO/SnO2 composite
Authors: He Jing , Zhao Zhen , Zhang Lei , Jiao Wanli 
Published: March 2022

Abstract
Commercial carbon fibers (CFs) were functionalized with NiO/SnO2 composite powders via a simple liquid phase deposition method followed by heat treatment and the influences of CFs content on the micro-structure and gas sensing performances of the CFs/NiO/SnO2 gas sensor were investigated. The results indicate that the distinctive one-dimensional CFs overlapped with each other, forming a large number of pores inside the CFs/NiO/SnO2 composite, which increases the effective reaction area between sensitive materials and target gases greatly. The CFs/NiO/SnO2 gas sensor with 0.5 wt% CFs exhibits a good sensitivity, selectivity and excellence response-recovery characteristic to formaldehyde at lower operation temperature of 170 °C. Notably, the detectable concentration of HCHO is as low as 1 ppm, indicating a certain application prospect in formaldehyde detection. And the electronic transmission bridge mechanism is performed to explain the gas sensing mechanism, which plays a certain role in the functional application of CF.
Bayesian vs frequentist: comparing Bayesian model selection with a frequentist approach using the iterative smoothing method
Authors: Koo Hanwool , Keeley Ryan E. , Shafieloo Arman , L'Huillier Benjamin 
Published: March 2022

Abstract
We have developed a frequentist approach for model selection which determines the consistency between any cosmological model and the data using the distribution of likelihoods from the iterative smoothing method. Using this approach, we have shown how confidently we can conclude whether the data support any given model without comparison to a different one. In this current work, we compare our approach with the conventional Bayesian approach based on the estimation of the Bayesian evidence using nested sampling. We use simulated future Roman (formerly WFIRST)-like type Ia supernovae data in our analysis. We discuss the limits of the Bayesian approach for model selection and show how our proposed frequentist approach can perform better in the falsification of individual models. Namely, if the true model is among the candidates being tested in the Bayesian approach, that approach can select the correct model. If all of the options are false, then the Bayesian approach will select merely the least incorrect one. Our approach is designed for such a case and we can conclude that all of the models are false.
Cosmic birefrigence: cross-spectra and cross-bispectra with CMB anisotropies
Authors: Greco Alessandro , Bartolo Nicola , Gruppuso Alessandro 
Published: March 2022

AbstractParity-violating extensions of Maxwell electromagnetism induce a rotation of the linear polarization plane of photons during propagation. This effect, known as cosmic birefringence, impacts on the Cosmic Microwave Background (CMB) observations producing a mixing ofEandBpolarization modes which is otherwise null in the standard scenario. Such an effect is naturally parametrized by a rotation angle which can be written as the sum of an isotropic componentα0and an anisotropic oneδα(n̂). In this paper we compute angular power spectra and bispectra involving δα and the CMB temperature and polarization maps. In particular, contrarily to what happens for the cross-spectra, we show that even in absence of primordial cross-correlations between the anisotropic birefringence angle and the CMB maps, there exist non-vanishing three-point correlation functions carrying signatures of parity-breaking physics. Furthermore, we find that such angular bispectra still survive in a regime of purely anisotropic cosmic birefringence, which corresponds to the conservative case of havingαo= 0. These bispectra represent an additional observable aimed at studying cosmic birefringence and its parity-violating nature beyond power spectrum analyses. They provide also a way to perform consistency checks for specific models of cosmic birefringence. Moreover, we estimate that among all the possible birefringent bispectra,〈δαTB〉and〈δαEB〉are the ones which contain the largest signal-to-noise ratio. Once the cosmic birefringence signal is taken to be at the level of current constraints, we show that these bispectra are within reach of future CMB experiments, as LiteBIRD.
Transition from the ballistic to the snake regime of a femtosecond laser through a turbid medium via Monte Carlo simulation
Authors: Ren Yuhu , Jian Jimo , Tan Wenjiang , Wang Jing , Chen Tao , Xia Wei 
Published: March 2022

Abstract
We study the transition from the ballistic to the snake regime of a femtosecond laser through a turbid medium via Monte Carlo simulation. The results show that the transition depth of the ballistic to the snake regime of a femtosecond laser through a turbid medium is close to the surface of the scattering volume. The transition process depends on the scattering coefficient of the turbid medium. Unlike the decay of the intensities of the ballistic photons governed by Beer–Lambert law, the intensities of the snake photons first increase with an increase of the thickness of the turbid medium and then decrease with a further increase of the thickness, for all scattering coefficients ranging from 10 to 20 cm−1. Further, we study the balance point of the intensity of the ballistic photons and the snake photons, which also depends on the scattering coefficient and the half-acceptance angle. The transmission depth corresponding to the transition balance point decreases with an increase of the scattering coefficient. In addition, for the transition balance point, the product of the transmission depth and scattering coefficient is approximately a constant (∼2) for a specific simulation configuration.

Published: March 2022

Abstract
An effective approach to obtain a single-frequency laser with low intensity noise is presented in this paper, which is implemented by employing a gain medium with the small stimulated-emission cross section (SECS). When the adopted Nd:YAP (Nd:YAlO3) gain medium with SECS of 4.6×10−19 cm2 is replaced by Nd:CYA (Nd:CaYAlO4) gain medium with SECS of 1.04×10−19 cm2, the frequency of measured intensity noise reached shot noise limit obviously reduces from 2.49 to 1.5 MHz, which agrees well with the theoretical predictions. On this basis, a single-frequency continuous-wave (CW) Nd:CYA laser with low intensity noise is first achieved. The attained output power of the Nd:CYA laser is 1.12 W. The achieved single-frequency CW 1080 nm laser will satisfy the requirements of the squeezed and entangled light generation.

Authors: Liu Zhaoxiang , Zhang Haochen 
Published: March 2022

Abstract
Ultra-high molecular weight polyethylene is a kind of popular engineering material because of its unique properties stemming from high molecular weights. Nowadays, the preparations and applications of this type of material are widely researched. This review mainly focuses on the preparation of ultra-high molecular weight polyethylene using three types of typical catalysts (heterogeneous Ziegler-Natta catalysts, Fujita’s catalysts and α-Diimine Nickel (II) catalysts) and applications in two significant areas (bulletproof membranes and lithium-ion batteries). Ziegler-Natta catalysts and Fujita’s catalysts favor the synthesis of linear ultra-high molecular weight polyethylene, but α-Diimine Nickel (II) catalysis favors β-hydride elimination which leads to branched products. Changes in steric, composition, activators, temperature and pressure will affect the tendency towards different mechanisms and influence structures and properties of final products.

Authors: Wang Jingwen , Zhang Xu 
Published: March 2022

Abstract
The shape of the leading and trailng edges of aero-engine blades has a significant influence on its aerodynamic performance. At present, the method of manual inspection based on the standard pattern is mainly used to analyze the shape of the leading, and trailing edges, which has the problems of low efficiency, poor repeatability and inconsistent evaluation results. An automatic shape evaluation method based on eigenvalues is proposed in this paper. Firstly, the blade profile and its mean camber line are segmented and fitted. Then, evaluation indexes are given for the five unqualified edge shapes respectively according to the curvature characteristics and profile variation characteristics. Finally, the shape of the blade edge is evaluated with the eigenvalues calculated. Experiments show that the proposed method can realize the automatic shape evaluation of blade leading and trailng edges, and can adapt to different types of blades and different acceptance standards, which effectively improves the efficiency of blade profile quality inspection.
