Gender differences in emotional connotative meaning of words measured by Osgood’s semantic differential techniques in young adults
Authors: Chapman Robert M. , Gardner Margaret N. , Lyons Megan 
Published: April 2022

AbstractSemantic differential techniques are a useful, well-validated tool to assess affective processing of stimuli and determine how that processing is impacted by various demographic factors, such as gender. In this paper, we explore differences in connotative word processing between men and women as measured by Osgood’s semantic differential and what those differences imply about affective processing in the two genders. We recruited 94 young participants (47 men, 47 women, ages 18–39) using an online survey and collected their affective ratings of 120 words on three rating tasks: Evaluation (E), Potency (P), and Activity (A). With these data, we explored the theoretical and mathematical overlap between Osgood’s affective meaning factor structure and other models of emotional processing commonly used in gender analyses. We then used Osgood’s three-dimensional structure to assess gender-related differences in three affective classes of words (words with connotation that is Positive, Neutral, or Negative for each task) and found that there was no significant difference between the genders when rating Positive words and Neutral words on each of the three rating tasks. However, young women consistently rated Negative words more negatively than young men did on all three of the independent dimensions. This confirms the importance of taking gender effects into account when measuring emotional processing. Our results further indicate there may be differences between Osgood’s structure and other models of affective processing that should be further explored.
Asset pricing and nominal price illusion in China
Authors: Yang Pujian , Yang Liu 
Published: April 2022

AbstractBased on the Fama’s three-factor model (FF3) and five-factor model (FF5), this study adds a low-priced stock premium factor LPP, and then builds a new four-factor and six-factor model respectively to examine the impact of low-price premium (LPP) on the pricing of China’s stock market. The research indicates that LPP is a reliable and effective pricing component in China’s A-share market, and it may be used as a systematic factor in the Chinese stock market’s asset pricing model. The LPP factor shows a strong negative association with stock excess returns. And the inclusion of the LPP in the FF3 and FF5 still passes the robustness test. Meanwhile, the six-factor model created by combining the LPP factor with the FF5 could explain Chinese stock market pricing better.
Mutational background influencesP. aeruginosaciprofloxacin resistance evolution but preserves collateral sensitivity robustness
Authors: Hernando-Amado Sara , Laborda Pablo , Valverde José Ramón , Martínez José Luis 
Published: April 2022

SignificanceBacterial adaptation to the presence of an antibiotic often involves evolutionary trade-offs, such as increased susceptibility to other drugs (collateral sensitivity). Its exploitation to design improved therapeutic strategies is only feasible if collateral sensitivity is robust, reproducible, and emerges in resistant mutants; these issues are rarely addressed in available publications. We describe a robust collateral sensitivity phenotype that emerges in different antibiotic-resistance mutational backgrounds, due to different genetic events, and propose therapeutic strategies effective for treating infections caused byPseudomonas aeruginosaantibiotic-resistant mutants. Since conserved collateral sensitivity phenotypes do not confer adaptation to the presence of antibiotics, our results are also relevant for understanding convergent evolution processes in which the force selecting the emerging phenotype remains unclear.
Preclinical evaluation of a precision medicine approach to DNA vaccination in type 1 diabetes
Authors: Postigo-Fernandez Jorge , Firdessa-Fite Rebuma , Creusot Rémi J. 
Published: April 2022

Significance
Antigen-specific immunotherapy may be improved by focusing on epitopes that are disease-relevant and known to be presented on an individual’s human leukocyte antigen (HLA) haplotype, while targeting T cells across multiple antigens and including specific neoepitopes that are not present in protein antigens and/or not produced beyond inflamed sites. Here, we provide proof of principle that such a strategy applied to tolerogenic DNA vaccination is effective in a preclinical model of autoimmune diabetes, paving the way for precision medicine using endogenously encoded epitopes. It takes a minimum number of regular treatments to achieve a level of tolerance and regulation that is needed to limit insulitis and provide sustained protection before treatment may be discontinued or reduced in frequency.
Mice exhibit stochastic and efficient action switching during probabilistic decision making
Authors: Beron Celia C. , Neufeld Shay Q. , Linderman Scott W. , Sabatini Bernardo L. 
Published: April 2022

SignificanceTo obtain rewards in changing and uncertain environments, animals must adapt their behavior. We found that mouse choice and trial-to-trial switching behavior in a dynamic and probabilistic two-choice task could be modeled by equivalent theoretical, algorithmic, and descriptive models. These models capture components of evidence accumulation, choice history bias, and stochasticity in mouse behavior. Furthermore, they reveal that mice adapt their behavior in different environmental contexts by modulating their level of stickiness to their previous choice. Despite deviating from the behavior of a theoretically ideal observer, the empirical models achieve comparable levels of near-maximal reward. These results make predictions to guide interrogation of the neural mechanisms underlying flexible decision-making strategies.

Significance
Atomic defects in solid-state materials are promising candidates as quantum bits, or qubits. New materials are actively being investigated as hosts for new defect qubits; however, there are no unifying guidelines that can quantitatively predict qubit performance in a new material. One of the most critical property of qubits is their quantum coherence. While cluster correlation expansion (CCE) techniques are useful to simulate the coherence of electron spins in defects, they are computationally expensive to investigate broad classes of stable materials. Using CCE simulations, we reveal a general scaling relation between the electron spin coherence time and the properties of qubit host materials that enables rapid and quantitative exploration of new materials hosting spin defects.
Ultrafast isolated molecule imaging without crystallization

Published: April 2022

Significance
Excitation of molecules by an ultrashort laser pulse creates rotational wave packets that lead to transient alignment of the molecules along the laser polarization direction. Here, we show that a train of ultrashort laser pulses can be used to enhance the degree of alignment to a high level such that the diffraction from precisely timed ultrashort electron beams may be used to reconstruct the structure of the isolated molecules with atomic resolution through a coherent diffraction imaging technique. Our results mark a great step toward imaging noncrystallized molecules with atomic resolution and pave the way for creation of three-dimensional “molecular movies” at the femtosecond time scale and atomic spatial scale.
Metasurface-loaded printed monopole antenna: tailoring impedance for wideband radiation
Authors: Qu Bingyue , Yan Sen , Wang Jiafu , Pang Yongqiang , Zhang Anxue , Xu Zhuo 
Published: April 2022

Abstract
In this paper, we propose a method of designing a wideband printed monopole antenna (PMA) by loading metasurface on its back. The metasurface-loaded PMA prototype is a double-sided structure, with the printed monopole on the front side and the metasurface etched on the back side, respectively. Driven by the printed monopole structure in the near-field zone, the metasurface can behave inductively or capacitively. By adjusting the geometrical parameters, the impedance of the metasurface can be tailored so as to compensate the mismatched impedance of the original printed monopole in a wide band, leading to a wideband omnidirectional radiation. To verify this method, a light-weight PMA is designed, fabricated and measured. Analyses of the impedance and the surface current distributions are employed in the design process. The height of the proposed PMA is 20.0 mm, about 16% of the wavelength corresponding to the lowest operating frequency. Both the simulated and measured results show that the antenna can achieve highly efficient omnidirectional radiation in 2.50–4.75 GHz and the relative bandwidth achieves up to 62%. This work provides an effective alternative of designing wideband PMA, and may find wide applications in modern wireless communications.
Nanoscale pattern formation on silicon surfaces bombarded with a krypton ion beam: experiments and simulations
Authors: Seo J , Pearson D A , Bradley R M , Kim J-S 
Published: April 2022

Abstract
The nanoscale patterns produced by bombardment of the (100) surface of silicon with a 2 keV Kr ion beam are investigated both experimentally and theoretically. In our experiments, we find that the patterns observed at high ion fluences depend sensitively on the angle of incidence Θ. For Θ values between 74° and 85°, we observe five decidedly different kinds of morphologies, including triangular nanostructures traversed by parallel-mode ripples, long parallel ridges decorated by short-wavelength ripples, and a remarkable mesh-like morphology. In contrast, only parallel-mode ripples are present for low ion fluences except for Θ = 85°. Our simulations show that triangular nanostructures that closely resemble those in our experiments emerge if a linearly dispersive term and a conserved Kuramoto–Sivashinsky nonlinearity are appended to the usual equation of motion. We find ridges traversed by ripples, on the other hand, in simulations of the Harrison–Pearson–Bradley equation (Harrison et al 2017 Phys. Rev. E 96 032804). For Θ = 85°, the solid surface is apparently stable and simulations of an anisotropic Edwards–Wilkinson equation yield surfaces similar to those seen in our experiments. Explaining the other two kinds of patterns we find in our experiments remains a challenge for future theoretical work.
Three-dimensional translation vibration measurement system based on linear array sensor and composite fringe pattern
Authors: Zhong Jianfeng , Liu Dongming , Wu Shengyuan , Li Siyu , Zhong Shuncong , Liang Wei 
Published: April 2022

Abstract
The vibration signal of a structure gives crucial information to understand its condition. A novel three-dimensional (3D) vibration measurement system is proposed, based on a linear array sensor (LAS) and a composite fringe pattern (CFP), for monitoring a rigid structure with translation displacement along each direction. The CFP is composed of three sinusoidal fringe sets. Two parallel sinusoidal fringe sets on both sides of the CFP and an inclined one in the middle. The displacement along the imaging optical axis could be obtained from the center distance variation of the parallel fringe sets in the recorded CFP. Meanwhile, the vertical displacement could be acquired from the variation of the center distance ratio of the fringe sets. The horizontal displacement could be obtained by locating the symmetric center of the parallel fringe intensity. A peak locating algorithm was created to realize sub-pixel displacement measurement without an increase in the amount of computation. Simulation results verify the feasibility, effectiveness and robustness of the proposed algorithms. The measurement performance of the proposed system was also verified by comparison experiments, whose results demonstrated that the proposed system is capable of recovering structural 3D displacements. Therefore, the proposed vibration monitoring system could be recommended for real engineering applications in the 3D translation vibration monitoring of rigid structures.

/SiO2 quantum dots (QDs) are prepared by a ligand-mediated hot injection method in which 3-aminopropyl-triethoxysilane (APTES) is used instead of the usual oleylamine (OAm) ligand. Through the hydrolysis of amino groups, a thin silicon layer is formed on the QD surface, improving the stability and without causing the aggregation of QDs. We find that the ratio of I/Br and the size of QDs can be tuned by adjusting the APTES amount. Moreover, this ligand-mediated synthesis effectively passivates the surface defects, so the photoluminescence quantum yield is remarkably improved, and the carrier lifetime is prolonged. The amplified spontaneous emission is achieved under 532 nm nanosecond laser excitation. Compared with the original CsPbBrI2-OAm QD films, the threshold of CsPbBr

Deterioration of ion beam neutralization caused by reflection of electrostatic solitary waves within pulsed ion beam
Authors: Lan Chaohui , Chen Qiming , Liu Jianli , Zhao Liangchao , E Peng 
Published: April 2022

Abstract
The neutralization of an ion beam pulse directly by electron injection excites the two-stream instability of neutralizing electrons and gives rise to an electrostatic solitary wave (ESW) in the long time limit. The ESW propagates stably and reflects back and forth in the potential well of the ion beam pulse. Through a two-dimensional particle-in-cell code, we numerically simulated the whole neutralization process of the ion beam pulse as well as the excitation and propagation of the ESW. It is found that the reflections of the ESW at the edges of the ion beam pulse cause a lot of neutralizing electrons to be thrown out, forming escaping electrons released in a pulsed manner. Each reflection of the ESW accelerates the reduction of the neutralization degree and brings a small disturbance to the ESW. The accumulative effect of multiple reflections results in rapid collapse of the ESW at the end. The reflections of the ESW at the head and tail of the beam pulse cause the ion beam to lose more neutralizing electrons than the slow attenuation of the ESW inside the ion beam.
3D particle simulations of positive air–methane streamers for combustion
Authors: Bouwman Dennis , Teunissen Jannis , Ebert Ute 
Published: April 2022

Abstract
Streamer discharges can be used as a primary source of reactive species for plasma-assisted combustion. In this research we investigate positive streamers in a stoichiometric air–methane mixture at 1 bar and 300 K with a three-dimensional particle-in-cell model for the electrons. We first discuss suitable electron scattering cross sections and an extension of the photoionization mechanism to air–methane mixtures. We discuss that the addition of 9.5% methane leaves electron transport and reaction coefficients essentially unchanged, but it largely suppresses photoionization and shortens the photon mean free path. This leads to (1) accelerated streamer branching, (2) higher electric field enhancement at the streamer head, (3) lower internal electric fields, and (4) higher electron densities in the streamer channel. We also calculate the time-integrated energy density deposited during the evolution of positive streamers in background electric fields of 12.5 and 20 kV cm−1. We find typical values of the deposited energy density in the range of 0.5–2.5 kJ m−3 within the ionized interior of streamers with a length of 5 mm; this value is rather independent of the electric fields applied here. Finally we find that the energy deposited in the inelastic electron scattering processes mainly produces reactive nitrogen species: N2 triplet states and N, but also O and H radicals. The production of H2 and O2 singlet states also occurs albeit less pronounced. Our calculation of the primary production of reactive species can for example be used in global chemistry models.
Plebański-Demiański solutions with dynamical torsion and nonmetricity fields
Authors: Bahamonde Sebastian , Gigante Valcarcel Jorge , Järv Laur 
Published: April 2022

Abstract
We construct Plebański-Demiański stationary and axisymmetric solutions with two expanding and double principal null directions in the framework of Metric-Affine gauge theory of gravity. Starting from the new improved form of the metric with vanishing cosmological constant recently achieved by Podolský and Vrátný, we extend this form in the presence of a cosmological constant and derive the conditions under which the physical sources of the torsion and nonmetricity tensors provide dynamical contributions preserving it in Weyl-Cartan geometry. The resulting black hole configurations are characterised by the mass, orbital angular momentum, acceleration, NUT parameter, cosmological constant and electromagnetic charges of the Riemannian sector of the theory, as well as by the spin and dilation charges of the torsion and nonmetricity fields. The former is subject to a constraint representing a decoupling limit with the parameters responsible of axial symmetry, beyond which the geometry of the space-time is expected to be corrected.
Transport and confinement in bilayer chiral borophene
Authors: Albuhairan Hassan Y , Abdullah H M , Schwingenschlögl U 
Published: April 2022

Abstract
We employ a four-band continuum model to study the transport and confinement in an n-p-n junction in bilayer chiral borophene for both the identical- and opposite-chirality configurations. We demonstrate the existence of topological states in a domain wall between domains of opposite-chirality bilayer chiral borophene with reversed layer stacking. An interlayer bias modifies the conductance of the identical-chirality configuration but not that of the opposite-chirality configuration, and it induces a layer localization of the bound and topological states. Our findings suggest paths toward utilization of the layer degree of freedom in bilayer chiral borophene in future electronic devices.
A novel fault current limiter topology design based on liquid metal current limiter

Published: April 2022

Abstract
The liquid metal current limiter (LMCL) is regarded as a viable solution for reducing the fault current in a power grid. But demonstrating the liquid metal arc plasma self-pinching process of the resistive wall, and reducing the erosion of the LMCL are challenging, not only theoretically, but also practically. In this work, a novel LMCL is designed with a resistive wall that can be connected to the current-limiting circuit inside the cavity. Specifically, a novel fault current limiter (FCL) topology is put forward where the novel LMCL is combined with a fast switch and current-limiting reactor. Further, the liquid metal self-pinch effect is modeled mathematically in three dimensions, and the gas-liquid two-phase dynamic diagrams under different short-circuit currents are obtained by simulation. The simulation results indicate that with the increase of current, the time for the liquid metal-free surface to begin depressing is reduced, and the position of the depression also changes. Different kinds of bubbles formed by the depressions gradually extend, squeeze, and break. With the increase of current, the liquid metal takes less time to break, but breaks still occur at the edge of the channel, forming arc plasma. Finally, relevant experiments are conducted for the novel FCL topology. The arcing process and current transfer process are analyzed in particular. Comparisons of the peak arc voltage, arcing time, current limiting efficiency, and electrode erosion are presented. The results demonstrate that the arc voltage of the novel FCL topology is reduced by more than 4.5 times and the arcing time is reduced by more than 12%. The erosions of the liquid metal and electrodes are reduced. Moreover, the current limiting efficiency of the novel FCL topology is improved by 1%‒5%. This work lays a foundation for the topology and optimal design of the LMCL.

AMIGOS III: pseudo-torsion angle visualization and motif-based structure comparison of nucleic acids
Authors: Shine Morgan , Zhang Chengxin , Pyle Anna Marie 
Published: April 2022

Abstract

Motivation
The full description of nucleic acid conformation involves eight torsion angles per nucleotide. To simplify this description, we previously developed a representation of the nucleic acid backbone that assigns each nucleotide a pair of pseudo-torsion angles (eta and theta defined by P and C4ʹ atoms; or etaʹ and thetaʹ defined by P and C1ʹ atoms). A Java program, AMIGOS II, is currently available for calculating eta and theta angles for RNA and for performing motif searches based on eta and theta angles. However, AMIGOS II lacks the ability to parse DNA structures and to calculate etaʹ and thetaʹ angles. It also has little visualization capacity for 3D structure, making it difficult for users to interpret the computational results.

Results
We present AMIGOS III, a PyMOL plugin that calculates the pseudo-torsion angles eta, theta, etaʹ and thetaʹ for both DNA and RNA structures and performs motif searching based on these angles. Compared to AMIGOS II, AMIGOS III offers improved pseudo-torsion angle visualization for RNA and faster nucleic acid worm database generation; it also introduces pseudo-torsion angle visualization for DNA and nucleic acid worm visualization. Its integration into PyMOL enables easy preparation of tertiary structure inputs and intuitive visualization of involved structures.
