Collectivities in translation (studies)
Authors: Dizdar Dilek , Rozmysłowicz Tomasz 
Published: March 2023

AbstractSince the cultural and social turn, translation studies has been interested in the role translation practices play in the construction of the socio-cultural world. In particular, it has been concerned with the effects translation practices have on the formation of all kinds of groups, communities or identities: national cultures, genders, social/political movements, and linguistic minorities, for example, have been examined in different ways as to their translational constructedness. In this introductory article, the authors propose to bring these various research endeavours together under one conceptual umbrella by adopting the notion of ‘collectivities.’ The notion serves as a cover term encompassing different shapes, durations, and sizes of collectivities and as a heuristic device within a coherent framework. The analytical value of such a framework, it is argued, consists in integrating existing and future research by relating individual approaches to each other and comparing them.

Published: March 2023

Abstract
The field of human-animal interaction (HAI) has experienced prolific growth in the scope, breadth, and rigor of research conducted on animal-assisted interventions (AAIs). As knowledge regarding the preliminary efficacy of AAIs on outcomes of human health and wellbeing continues to accumulate, so has information regarding the feasibility, safety, and acceptability of AAIs. This progression, combined with an increase in funding opportunities, institutional resources, and growing recognition of the field from mental and medical health professionals, has led to more widespread implementation of randomized controlled trials (RCTs) in the field. While conducting RCTs in any field of study is an intensive and complex undertaking, researchers conducting RCTs to evaluate the efficacy of AAIs are faced with unique considerations. The goal of this manuscript is to discuss these complexities and considerations surrounding conducting an RCT of an AAI program in regard to study planning, conceptualization, design, implementation, and dissemination. We highlight common confounders in HAI research and provide strategies for minimizing or ameliorating them. Recommendations pertain to such unique issues as ethical considerations, theory, control and comparison groups, sampling, implementation fidelity, and transparent reporting of findings. These considerations and recommendations seek to aid HAI researchers in the design, implementation, and dissemination of future RCTs to continue to advance the rigor of the field.
(De)coupling Positional Whiteness and White Identities through “Good English” in Singapore
Authors: Babcock Joshua 
Published: March 2023

AbstractEnglish in Singapore occupies an ambivalent status as both global bridge and threat to local “cultural values” (Tan 2017). English is also constructed as threatened by Singlish, or Singaporean Colloquial English (Wee 2018). This article first elaborates the historical-institutional production of a covert raciolinguistic community—“Caucasian” English speakers—whose speech ideologically contrasts with Singaporeans’ “non-native” English. It then analyzes a crowdsourced self-help column, “English as It Is Broken,” and participant observation at a Singlish awareness class. I argue that the figure of the native-English-speaking foreigner (by default white and, increasingly, American) continues to anchor what counts as “Good English” and rescales intersectional self- and other evaluations of Singaporeans’ linguistic deficiency. Good English thus invites aspirational investments in whiteness-as-position (a superordinate position in global, racializing hierarchies) but remains a target that Singaporeans are cast as forever failing to meet due to their nonwhite identities (not “being” white).
Dynamics of a solitonic vortex in an anisotropically trapped superfluid
Authors: Gomez Llorente J M , Plata J 
Published: March 2023

Abstract
We analytically study the dynamics of a solitonic vortex (SV) in a superfluid confined in a non-axisymmetric harmonic trap. The study provides a framework for analyzing the role of the trap anisotropy in the oscillation of SVs observed in recent experiments on atomic Bose and Fermi superfluids. The emergence of common and statistics-dependent features is traced in a unified approach to both types of fluid. Our description, built in the hydrodynamic formalism, is based on a Lagragian approach which incorporates the vortex location as dynamical parameters of a variational ansatz. Previous operative Hamiltonian pictures are recovered through a canonically traced procedure. Our results improve the understanding of the experimental findings. Some of the observed features are shown to be specific to the tri-axial anisotropy of the trap. In particular, we characterize the nontrivial dependence of the oscillation frequency on the trapping transversal to the vortical line. The study reveals also the crucial role played by the nonlinear character of the dynamics in the observed oscillation: for the considered experimental conditions, the frequency, and, in turn, the effective inertial mass of the vortex, are found to significantly depend on the amplitude of the generated motion. It is also uncovered how the coupling with collective modes of the fluid induces a non-negligible shift in the oscillation frequency. The appearance of fine-structure features in the SV trajectory is predicted.

Published: March 2023

Abstract
2D decorated nanostructures are fast emerging as efficient electrode materials for electrochemical devices. Au decorated SnO2, synthesized using co-precipitation and hydrothermal methods, can become a useful electrode material for supercapacitors. Au incorporation helps to mitigate the conductivity issues of SnO2 nanostructures. The superior 2D-flake like morphology leads to appreciable performance enhancement, with specific capacitance of 234 F g−1 at 1 A g−1 current density, which is much larger than that observed in pristine SnO2. The high cycling stability of Au-decorated SnO2 clearly shows its usefulness for high-performance supercapacitors. A theoretical model is also reported to explain the electrochemical results.

Abstract
We review recent progress and motivate the need for further developments in nuclear optical potentials that are widely used in the theoretical analysis of nucleon elastic scattering and reaction cross sections. In regions of the nuclear chart away from stability, which represent a frontier in nuclear science over the coming decade and which will be probed at new rare-isotope beam facilities worldwide, there is a targeted need to quantify and reduce theoretical reaction model uncertainties, especially with respect to nuclear optical potentials. We first describe the primary physics motivations for an improved description of nuclear reactions involving short-lived isotopes, focusing on its benefits for fundamental science discoveries and applications to medicine, energy, and security. We then outline the various methods in use today to build optical potentials starting from phenomenological, microscopic, and ab initio methods, highlighting in particular, the strengths and weaknesses of each approach. We then discuss publicly-available tools and resources facilitating the propagation of recent progresses in the field to practitioners. Finally, we provide a set of open challenges and recommendations for the field to advance the fundamental science goals of nuclear reaction studies in the rare-isotope beam era. This paper is the outcome of the Facility for Rare Isotope Beams Theory Alliance (FRIB-TA) topical program ‘Optical Potentials in Nuclear Physics’ held in March 2022 at FRIB. Its content is non-exhaustive, was chosen by the participants and reflects their efforts related to optical potentials.
Atomic-scale interpretation of the quantum oscillations in cuprate superconductors
Authors: Lee K S , Kim J-J , Joo S H , Park M S , Yoo J H , Gu Genda , Lee Jinho 
Published: March 2023

Abstract
Cuprate superconductors display unusual features in both k space and real space as the superconductivity is suppressed—a broken Fermi surface, charge density wave, and pseudogap. Contrarily, recent transport measurements on cuprates under high magnetic fields report quantum oscillations (QOs), which imply rather a usual Fermi liquid behavior. To settle the disagreement, we investigated Bi2Sr2CaCu2O8+δ
under a magnetic field in an atomic scale. A particle-hole (p–h) asymmetrically dispersing density of states (DOSs) modulation was found at the vortices on a slightly underdoped sample, while on a highly underdoped sample, no trace of the vortex was found even at 13 T. However, a similar p–h asymmetric DOS modulation persisted in almost an entire field of view. From this observation, we infer an alternative explanation of the QO results by providing a unifying picture where the aforementioned seemingly conflicting evidence from angle-resolved photoemission spectroscopy, spectroscopic imaging scanning tunneling microscopy, and magneto-transport measurements can be understood solely in terms of the DOS modulations.
Correlation-based full-waveform shear wave elastography
Authors: Elmeliegy Abdelrahman M , Guddati Murthy N 
Published: March 2023

Abstract

Objective. With the ultimate goal of reconstructing 3D elasticity maps from ultrasound particle velocity measurements in a plane, we present in this paper a methodology of inverting for 2D elasticity maps from measurements on a single line. Approach. The inversion approach is based on gradient optimization where the elasticity map is iteratively modified until a good match is obtained between simulated and measured responses. Full-wave simulation is used as the underlying forward model to accurately capture the physics of shear wave propagation and scattering in heterogeneous soft tissue. A key aspect of the proposed inversion approach is a cost functional based on correlation between measured and simulated responses. Main results. We illustrate that the correlation-based functional has better convexity and convergence properties compared to the traditional least-squares functional, and is less sensitive to initial guess, robust against noisy measurements and other errors that are common in ultrasound elastography. Inversion with synthetic data illustrates the effectiveness of the method to characterize homogeneous inclusions as well as elasticity map of the entire region of interest. Significance. The proposed ideas lead to a new framework for shear wave elastography that shows promise in obtaining accurate maps of shear modulus using shear wave elastography data obtained from standard clinical scanners.

Published: March 2023

Abstract
Numerical and analytical approaches to plasma density determination from the ion current to cylindrical Langmuir probe are validated on hairpin probe measurements. An argon inductively coupled plasma discharge in a pressure range from 4.5 mTorr to 27 mTorr is studied. The discharge input power is varied in the range from 200 to 800 W, giving a plasma density in the range from 109 to 1011 cm−3. The approaches used for plasma density determination are analytical collisionless orbital motion limit theory, fluid semianalytical model of ion radial motion with ion collisions and particle-in-cell with a Monte Carlo collisions model of ion current collection by the cylindrical Langmuir probe. The relative error of different models is shown. The ion collisions should be taken into account, even at relatively low pressures, in order to get a reliable plasma density value from the ion current to the Langmuir probe.

Published: March 2023

Abstract
In partially magnetized technological plasmas like magnetron discharges or Hall-effect thrusters, the interaction of gyrating electrons with the plasma boundary sheath plays an important role. This study shows that the interaction can be described as a dissipative process. It is assumed that the Debye length

is much smaller than the electron gyroradius

, and

r

in turn much smaller than the mean free path λ and the field gradient length l. Focusing on the scale of the gyroradius, the sheath is assumed as thin (

26 115009). The present research focuses on the subsequent evolution. It is shown that the gyromotion results in fast phase mixing with respect to the gyrophase which quickly restores the gyrophase invariance. In combination, the two phases of the sheath interaction constitute a mapping within the space of gyrophase invariant distributions. This combined process is dissipative and leads to isotropization. As an explicit comparison shows, it acts similarly to elastic electron-neutral collisions and can even dominate the latter in low pressure plasmas. A simplified version of the operator that applies for weakly anisotropic distributions is suited for practical simulation work.
Total-ionizing dose irradiation induced degradation behavior and mechanism of the Cascode GaN HEMTs
Authors: Cai X Z , Chen Y Q , Zhou C J 
Published: March 2023

Abstract
In this article, the effects of total ionizing dose (TID) irradiation and the annealing treatment on the degradation of the commercial Cascode GaN high-electron-mobility transistors (HEMTs) were investigated, and low frequency noise method (LFN) was carried out to analyze the defects. The DC characteristics show that the device after TID irradiation with different doses exhibits a negative drift of threshold voltage (V
th) and a remarkable increase of drain-source current (I
ds) with respect to the fresh one. Meanwhile, with increasing doses of the TID irradiation, the off-state drain leakage current increases, while the drain-source resistance decreases. The gate-lag characteristic gets better for the Cascode GaN HEMTs after TID irradiation. The transfer characteristics, output characteristics, blocking characteristics and capacitance characteristics of the devices can partly be restored by annealing treatment, but there is no pronounced influence on the gate-lag characteristics and drain-source resistance. The trap density extracted by the LFN method decreases in the Cascode GaN HEMTs after TID irradiation. The degradation behavior and mechanism of the Cascode GaN HEMTs under TID irradiation are analyzed. The experimental results may provide a useful reference for the design and space application of the Cascode GaN HEMTs.
Soft robotic finger with variable effective length enabled by an antagonistic constraint mechanism
Authors: Wang Xing , Kang Hanwen 
Published: March 2023

Abstract
Compared to traditional rigid robotics, soft robotics has attracted increasing attention due to its advantages in compliance, safety, and low cost. As an essential part of soft robotics, the soft robotic gripper also shows its superior while grasping objects with irregular shapes. Recent research has been conducted to improve grasping performance by adjusting the variable effective length (VEL). However, the existing VEL function achieved by mechanisms such as multi-chamber design or tunable stiffness shape memory material requires a complex pneumatic circuit design or a time-consuming phase-changing process. This work proposes a fold-based soft robotic finger with VEL function from 3D printing. It is experimentally tested and modeled by the hyperelastic material property. Mathematic and finite element modeling is conducted to study the bending behaviour of the proposed soft actuator. Most importantly, an antagonistic constraint mechanism is proposed to achieve the VEL, and the experiments demonstrate that better conformity is achieved. Finally, dual-mode grippers are designed and evaluated to demonstrate the advances of VEL on grasping performance.
Exact diagonalisation of photon Bose–Einstein condensates with thermo-optic interaction
Authors: Stein Enrico , Pelster Axel 
Published: March 2023

Abstract
Although photon Bose–Einstein condensates have already been used for studying many interesting effects, the precise role of the photon–photon interaction is not fully clarified up to now. In view of this, it is advantageous that these systems allow measuring both the intensity of the light leaking out of the cavity and its spectrum at the same time. Therefore, the photon–photon interaction strength can be determined once via analysing the condensate broadening and once via examining the interaction-induced modifications of the cavity modes. As the former method depends crucially on the concrete shape of the trapping potential and the spatial resolution of the used camera, interferometric methods promise more precise measurements. To this end, the present paper works out the impact of the photon–photon interaction upon the cavity modes. A quantum mechanical description of the photon–photon interaction, including the thermal cloud, builds the theoretical backbone of the method. An exact diagonalisation approach introduced here exposes how the effective photon–photon interaction modifies both the spectrum and the width of the photon gas. A comparison with a variational approach based on the Gross–Pitaevskii equation quantifies the contribution of the thermal cloud in the respective applications.
Lead-tungsten oxide interfaces designed as gigahertz/terahertz filters
Authors: Alkhamisi Manal M , Qasrawi A F , Khanfar Hazem K 
Published: March 2023

Abstract
Herein amorphous tungsten oxide thin films of thicknesses of 300 nm are coated onto semitransparent Pb films (100 nm) by the thermal evaporation technique under a vacuum pressure of 10−5 mbar. Optical investigations in these films have shown that Pb nanosheets enhances the light absorbability in the visible and infrared ranges of light without significant change in the energy band gap value. In addition deep analyses of the optical conductivity and terahertz cutoff frequency spectra of the Pb/WO3 optical filters revealed that the cutoff frequency value in the visible range of light is invariant with light signal energy indicating the possibly of filtering none-monochromatic light signals. On the other hand imposing an ac signal between the terminals of Pb/WO3/Au devices has proofed the ability of the device to perform as low pass and as band stop filters workable in the microwave frequency domain. The microwave cutoff frequency for this device reached ∼9 GHz nominating it for use in 5 G mobile technology. The current study showed that coating of tungsten oxide onto semitransparent Pb substrate and coverage small area of the top contact with Au can allow functioning the device as gigahertz/terahertz band filters suitable for communication technology.
Observational predictions of LQG motivated polymerized black holes and constraints from Sgr A* and M87*
Authors: Walia Rahul Kumar 
Published: March 2023

Abstract
Loop quantum gravity inspired partial polymer quantization in four-dimensional spacetime leads to a globally regular black hole with a single horizon. The polymerized black hole metric is characterized by the minimum length parameter k, and mimics the Schwarzschild black hole in the weak-field limit. We present an analytic and numerical investigation of the strong gravitational lensing and shadow morphology to determine the observational impacts of quantum effects. Interestingly, the light deflection angle, the angular separation between the outermost relativistic image, and magnification are significantly larger than those for the Schwarzschild black hole. Using the ray-tracing technique, we simulate the black hole shadows under three distinct optically thin accretion models: static spherical accretion, radially infalling spherical accretion, and the thin accretion disk model. Polymerized black holes' shadow morphology strongly depends on k. We derive constraints on k from the M87* and Sgr A* black hole shadow observations from the Event Horizon Telescope.

As a result, several years after the construction of a large radio telescope facility, the number of known GC pulsars will likely be increased accordingly. We suggest that currently GCs in the southern hemisphere could have higher possibilities for finding new pulsars.
