Core belief disruption amid the COVID-19 pandemic in Japanese adults
Authors: Matsudaira Izumi , Takano Yuji , Yamaguchi Ryo , Taki Yasuyuki 
Published: November 2021

AbstractDue to the rapid spread of the novel coronavirus disease (COVID-19) worldwide, most people have been forced to alter their lifestyles. This situation may affect the mental health of individuals through the disruption of core beliefs about humans, the world, and the self. Therefore, in this study, an online survey of Japanese adults was conducted to investigate the associations between subjective achievement and the burden of cooperation in preventive measures, disruption of core beliefs, and psychological distress. The results showed that pandemic-induced disruption of core beliefs occurred at a relatively low level in the general population of Japan. In addition, the achievement and psychological burden of preventive measures, reduced income due to the pandemic, and stressfulness of the pandemic were significantly associated with the level of the disruption of core beliefs. Moreover, the greater the disruption of core beliefs, the greater the psychological distress. These findings indicate that the violation of fundamental assumptions about life are an important factor determining mental health during a pandemic.

Published: November 2021

Cellulose is a glucose polymer and the most abundant biological material on earth. Because it is biodegradable and yet water insoluble, cellulose has been pursued in the past as a scaffold or base structural material for medical applications, sensors, and optical devices. Patterning of two cellulose polymers, cellulose acetate and cellulose acetate butyrate, by photoablative lithography at 172 nm has been demonstrated and is reported here. This 3D subtractive process yields complex micro- and nanostructures and optical components, including sinusoidal gratings and waveguides. Having a depth precision of 15 nm and requiring no photoresist or solvents, vacuum-ultraviolet photoetching of cellulose polymer films proceeds at a constant rate of ∼0.8 μm/h for depths of up to and beyond 25 μm when the intensity of the flat lamp is 10 mW cm−2. A polydimethylsiloxane (PDMS) microimprinting process, in which photoetched cellulose serves as a negative master mold for PDMS, provides feature sizes as small as 0.5 μm and allows for optical structures such as gratings to be integrated with microfluidic devices while eliminating the existing necessity of fabricating Si molds in a cleanroom environment.
Translesion polymerase eta both facilitates DNA replication and promotes increased human genetic variation at common fragile sites

Significance
Common fragile sites (CFSs) are normal loci that are genetically unstable under normal and oncogenic replication stress. Pol eta has been proposed to play a key role in CFS replication. Here, we show that in the absence of Pol eta, replication at five specific CFS loci is perturbed, with fork pausing observed at several sites. Sequence analysis showed that certain pause sites are associated with the presence of non-B DNA motifs, while others are not. Importantly, pause sites are located within regions of increased genetic variation in healthy human populations that could be attributed to Pol eta activity. Our data unveil a role for Pol eta in overcoming replication stress, reducing DNA breakage, and promoting genetic variation at CFSs.

Significance
Many people perceive crystals as the embodiment of perfect order, although in reality, it is well understood that monocrystals possess imperfections. By considering large anhydrite crystals from the famous Naica Mine (“Cueva de los cristales”), an extended picture begins to emerge, revealing a suite of correlated self-similar void defects spanning multiple length scales. These flaws in the macroscopic crystal likely stem from “seeds of imperfection” originating from a particle-mediated nucleation pathway. Hence, building a crystal could be viewed as nature stacking blocks in a game of Tetris, while slowly forgetting the game’s core concept and failing to fill rows completely.
The making of unaccompanied children
Authors: Yilmaz Birgul 
Published: November 2021

Abstract
This paper deals with the management of unaccompanied child migration. A legal framework laid out in international law aims to give internationally recognised human rights to children. These legal texts (re)invent the label of “child”, and more specifically, of “unaccompanied child”. This is a legally prescribed lexical label that discursively produces the figure of “child” as a legal, psychological and biometric surveillance object, resulting in ambivalent management of the children. In this paper, I show how this figure of the unaccompanied child is (re)invented in legal texts and then circulates in the humanitarian world via a process of entextualisation on supra/national and local levels in Greece. Drawing on eight months of ethnography on Lesvos Island, I demonstrate the tensions, disruptions, refusals and unsettling moments of struggle that arise when this definition and its related policies are implemented on the ground.
“May you fall [dead] while standing!”
Authors: Haokip Pauthang 
Published: November 2021

Abstract
This paper presents two types of maledictions in Thadou-Kuki. The first deals with the various forms of maledictions which on the surface appear as though they are curse words in terms of their forms and meanings. But a close examination reveals that the mere presence of such maledictions does not constitute cursing. Rather, it is the context of who said what to whom and why that determines whether they should be interpreted curses or not. The second deals with words that are used purely as abuses or insults and, as such, do not have such semantic or pragmatic ambiguities like the various forms of maledictions. The paper shows that maledictions are expressed with the help of imperatives of which the directive -în and the command tâng are used with slight nuances in meaning. That is, with the latter, the wish is more pronounced and indicates the true intent of the speaker to inflict harm upon the addressee, which the former lacks. Abuses or insults, on the other hand, are momentary emotional reactions to the things that happened around the speaker and unlike true curses are not carefully thought out expression of words. They are rather words that the speaker picked up as and when the situation demands and may involve an element of bragging.
Register variation in school EFL textbooks
Authors: Le Foll Elen 
Published: November 2021

Abstract
This study applies additive Multi-Dimensional Analysis (MDA) (Biber 1988) to explore the linguistic characteristics of ‘school English’ or ‘textbook English’. It seeks to find out how text registers commonly featured in English as a Foreign Language (EFL) textbooks differ from comparable registers found outside the EFL classroom. To this end, a Textbook English Corpus (TEC) of 43 coursebooks used in European schools is mobilised. The texts from six textbook register subcorpora and three target language corpora are mapped onto Biber’s (1998) ‘Involved vs. Informational’ dimension of General English. Register accounts for 63% of the variance in these dimension scores in the TEC. Additional factors such as textbook level, series and country of publication/use only play a marginal role in mediating textbook register variation. Textbook dialogues score considerably lower than the Spoken BNC2014, whereas Textbook Fiction scores closest to its corresponding reference Youth Fiction Corpus. Pedagogical and methodological implications are discussed.
Giving Succor to Extremism?
Authors: Stohler Stephan 
Published: November 2021

AbstractFree speech is essential to democracy and political participation. But scholars hold competing expectations about whether courts will protect free speech in similar ways for extremism. Drawing on free speech cases from high courts in Australia, Canada, India, and South Africa, as well as from the European Court of Human Rights, I show that judges are substantially less likely to support free speech in cases involving extremist claimants or extreme speech. Moreover, I demonstrate how judges tailor arguments in response to concerns about extremism. This evidence has implications for our understanding of judicial behavior and the role that courts play in preserving democracy.
Scaling Court Decisions with Citation Networks

Published: November 2021

AbstractTo compare court decisions in a systematic way, it is typically necessary to first read these decisions and then apply legal methods to them. Measurement models that support analysts in this manual labor usually rely on judges’ voting records. Since these data are often not available, we instead propose a latent-variable model that uses the widely available references in court decisions to measure the decisions’ latent position in their common case-space. We showcase our model in the context of forum shopping and forum selling of Germany’s lower courts.
A variational non-linear constrained model for the inversion of FDEM data*
Authors: Buccini A , Díaz de Alba P 
Published: November 2021

Abstract
Reconstructing the structure of the soil using non-invasive techniques is a very relevant problem in many scientific fields, like geophysics and archaeology. This can be done, for instance, with the aid of frequency domain electromagnetic (FDEM) induction devices. Inverting FDEM data is a very challenging inverse problem, as the problem is extremely ill-posed, i.e. sensible to the presence of noise in the measured data, and non-linear. Regularization methods substitute the original ill-posed problem with a well-posed one whose solution is an accurate approximation of the desired one. In this paper we develop a regularization method to invert FDEM data. We propose to determine the electrical conductivity of the ground by solving a variational problem. The minimized functional is made up by the sum of two term: the data fitting term ensures that the recovered solution fits the measured data, while the regularization term enforces sparsity on the Laplacian of the solution. The trade-off between the two terms is determined by the regularization parameter. This is achieved by minimizing an ℓ
2 − ℓ

q
functional with 0 < q ⩽ 2. Since the functional we wish to minimize is non-convex, we show that the variational problem admits a solution. Moreover, we prove that, if the regularization parameter is tuned accordingly to the amount of noise present in the data, this model induces a regularization method. Some selected numerical examples on synthetic and real data show the good performances of our proposal.
Barium titanate piezoelectric-film-based beam-array airflow sensor for wearable breath-monitoring application
Authors: Feng Guo-Hua , Su Pin-Cheng 
Published: November 2021

Abstract
This study presents a barium titanate (BaTiO3) film-based piezoelectric airflow sensor. This sensor integrated a piezoelectric beam array with a poly(dimethylsiloxane) orifice membrane as the core sensing component. The compact size of the micromachined device fit the requirements for a wearable device. The hydrothermally grown barium titanate film exhibited an orthorhombic crystal structure with good piezoelectric properties. We propose an algorithm to determine the airflow sensor performance using data from the measured piezoelectric signal and the displacement of the piezoelectric beam. This algorithm correlates the discharge coefficient of the core sensing component, Reynold’s number, airflow velocity, pressure difference across the component, displacement of the piezoelectric beam, strain of the barium titanate film, and generated charge from the sensor, which is rarely reported in the literature. The Young’s modulus and piezoelectric constant of the barium titanate film could also be derived as 100 GPa and 8 pC N−1, respectively. Utilizing this algorithm and the generated piezoelectric signal of the sensor, important breath parameters of a young male subject at rest were monitored.
Understanding composite negative differential resistance in niobium oxide memristors

Published: November 2021

Abstract
Volatile memristors, or threshold switching devices, exhibit a diverse range of negative differential resistance (NDR) characteristics under current-controlled operation and understanding the origin of these responses is of great importance for exploring their potential as nano-scale oscillators for neuromorphic computing. Here we use a previously developed two-zone, parallel memristor model to undertake a systematic analysis of NDR modes in two-terminal metal-oxide-metal devices. The model assumes that the non-uniform current distribution associated with filamentary conduction can be represented by a high current density core and a lower current-density shell where the core is assumed to have a memristive response due to Poole-Frenkel conduction and the shell is represented by either a fixed resistor or a second memristive region. A detailed analysis of the electrical circuits is undertaken using a lumped-element thermal model of the core-shell structure, and is shown to reproduce continuous and discontinuous NDR responses, as well as more complex compound behaviour. Finally, an interesting double-window oscillation behaviour is predicted and experimentally verified for a device with compound NDR behaviour. These results clearly identify the origin of different NDR responses and provide a strong basis for designing devices with complex NDR characteristics.
Probing topological quantum phase transitions via photonic spin Hall effects in spin-orbit coupled 2D quantum materials
Authors: Shah Muzamil 
Published: November 2021

Abstract
Topological photonics is an emerging field in photonics in which various topological and geometrical ideas are used to manipulate and control the behavior of light photons. The interplay between topological matter and the spin degree of freedom of photons provides new opportunities for achieving spin-based photonics applications. In this paper, the photonic spin Hall effect (PSHE) of reflected light from the surface of the topological silicene quantum systems subjected to external electric and radiation fields in the terahertz regime is theoretically investigated. By tuning the external electric and the applied laser fields, we can drive the silicenic system through different topological quantum phase transitions. We demonstrate that the in-plane and transverse spatial spin dependent shifts exhibit extreme values near Brewster’s angles and away from the optical transition frequencies. We reveal that the photonic spin Hall shifts are sensitive to the spin and valley indices as well as to the number of closed gaps. We believe that the spin and valley-resolved PSHE will greatly impact the research in spinoptics, spintronics, and valleytronics.

Abstract
The development of highly-efficient loading, targeted delivery and controlled-release of drug carrier systems is of great significance in tumor treatment. Although various kinds of nano-carriers have been widely studied as potential anticancer delivery materials, the major concern of cytotoxicity is still an important issue before real medical applications. This is due to the strong interactions between nano-structure carriers and biomacromolecules. Herein, a covalent organic framework (COF), triazine triphenyl imine (TTI), is proposed as a promising candidate for efficient delivery and release of the anti-cancer drug, doxorubicin (DOX), by using molecular dynamics simulations. Our results demonstrated that despite there being huge pores in TTI, enough contact sites can be provided to attract the drug by π–π interactions between the anthracene rings of DOX and the framework of TTI. The loading capacity of DOX on the TTI monolayer even reach 743% because the nanopores exclude some invalid adsorption sites that exist in other 2D nano-carriers. Interestingly, the DOX molecules can not only spontaneously adsorb on the surface of the TTI monolayer in natural conditions, but also effectively release from the TTI carrier under acidic pH level. For the TTI multilayers, similar loading capacity had also been achieved due to the pore walls also playing a key role in adsorbing the DOX molecules. Moreover, by simulating a model protein interacting with TTI, mild biocompatibility of TTI monolayer and multilayer could also be achieved due to the periodic nanopores limiting the excessive adsorption with the protein that could maintain the native structure. Our results highlight the essential roles of the patterned nano-porous structure in the TTI sheets for both efficient DOX loading and release, with high biocompatibility, and provides valuable insight into COF-based nano-carriers in potential drug delivery applications.
Surface lattice Green’s functions for high-entropy alloys
Authors: Nöhring Wolfram G , Grießer Jan , Dondl Patrick , Pastewka Lars 
Published: November 2021

Abstract
We study the surface elastic response of pure Ni, the random alloy FeNiCr and an average FeNiCr alloy in terms of the surface lattice Green’s function. We propose a scheme for computing per-site Green’s function and study their per-site variations. The average FeNiCr alloys accurately reproduces the mean Green’s function of the full random alloy. Variation around this mean is largest near the edge of the surface Brillouin-zone and decays as q
−2 with wavevector q towards the Γ-point. We also present expressions for the continuum surface Green’s function of anisotropic solids of finite and infinite thickness and show that the atomistic Green’s function approaches continuum near the Γ-point. Our results are a first step towards efficient contact calculations and Peierls–Nabarro type models for dislocations in high-entropy alloys.

Published: November 2021

Abstract
A systematic study of the synthetic procedure to improve quantum efficiency of luminescent hybrid perovskite QDs through ligand-assisted precipitation method is presented. Particularly, the influence of the dielectric constant and dipole moment of the antisolvent on the reaction time and the photophysical properties of the QDs is highlighted. After evaluating the influence of antisolvents and optimizing experimental parameters such as reaction time and Pb excess of the precursor, colloidal crystalline MAPbBr3 QDs with exceptionally high absolute quantum yield up to 97.7% in solution and 69.1% in solid film were obtained. Finally, MAPbBr3 QDs precipitated from anisole were processed like UV-curable nanocomposite as efficient down conversion layer resulting in very narrow green emission light-emitting diode.

Abstract
Positron emission particle tracking (PEPT) is a technique which allows the high-resolution, three-dimensional imaging of particulate and multiphase systems, including systems which are large, dense, and/or optically opaque, and thus difficult to study using other methodologies. In this work, we bring together researchers from the world’s foremost PEPT facilities not only to give a balanced and detailed overview and review of the technique but, for the first time, provide a rigorous, direct, quantitative assessment of the relative strengths and weaknesses of all contemporary PEPT methodologies. We provide detailed explanations of the methodologies explored, including also interactive code examples allowing the reader to actively explore, edit and apply the algorithms discussed. The suite of benchmarking tests performed and described within the document is made available in an open-source repository for future researchers.

Abstract
Dry lithography is a promising micro-/nanomanufacturing method owing to its advantages of being solution-free, its absence of undercut and resistance to swelling. However, heat-mode resists suitable for dry lithography are less reported. This work reports on the use of Ag-doped Sb2Te thin film as a heat-mode resist, and its etching selectivity and microstructures are investigated in detail. It is found that Ag1.44Sb2.19Te thin film possesses high etching selectivity in CHF3/O2 mixed gases and can act as a heat-mode resist. In order to elucidate the mechanism of high etching selectivity, the microstructures of the Ag-doped Sb2Te thin films are analyzed using x-ray diffraction, Raman spectra, x-ray photoelectron spectroscopy, and transmission electron microscopy methods. The results show that the etching selectivity is attributed to the phase separation of Ag1.44Sb2.19Te film and the formation of the Sb phase after laser exposure, leading to a reduction in etching resistance in CHF3/O2 mixed gases. In addition, pattern transfers from Ag1.44Sb2.19Te to SiO2 and Si substrates are achieved successfully and the etching selectivities of Si and SiO2 to Ag1.44Sb2.19Te are both higher than 2:1. This work may provide a useful guide for the research of dry lithography without wet development.
