Published: November 2021

Abstract
Recently, two-dimensional (2D) boron nanosheets have been predicted to exhibit exceptional physical and chemical properties, which is expected to be widely used in advanced electronics, optoelectronic, energy storage and conversion devices. However, the experimental application of 2D boron nanosheets in hydrogen evolution reactiuon (HER) has not been reported. Here, we have grown ultrathin boron nanosheets on tungsten foils via chemical vapor deposition. The prepared triclinic boron nanosheets are highly crystalline, which perfectly match the structure in the previous theoretical calculations. Notably, the boron nanosheets show excellent HER performance. The Tafel slope is only 64 mV dec−1 and the nanosheets can maintain good stability under long-time cycle in acidic solution. The improvement of performance is mainly due to the metal properties and a large number of exposed active sites on the boron nanosheets, which is confirmed by first-principle calculations.

Published: November 2021

Abstract
MoS2 is an intrinsic piezoelectric material which offers applications such as energy harvesting, sensors, actuators, flexible electronics, energy storage and more. Surprisingly, there are not any suitable, yet economical methods that can produce quality nanosheets of MoS2 in large quantities, hence limiting the possibility of commercialisation of its applications. Here, we demonstrate controlled synthesis of highly crystalline MoS2 nanosheets via liquid phase exfoliation of bulk MoS2, following which we report piezoelectric response from the exfoliated nanosheets. The method of piezo force microscopy was employed to explore the piezo response in mono, bi, tri and multilayers of MoS2 nanosheets. The effective piezoelectric coefficient of MoS2 varies from 9.6 to 25.14 pm V−1. We attribute piezoelectric response in MoS2 nanosheets to the defects formed in it during the synthesis procedure. The presence of defects is confirmed by x-ray photoelectron spectroscopy.
The linear and nonlinear instability of the Akhmediev breather
Authors: Grinevich P G , Santini P M 
Published: November 2021

Abstract
The Akhmediev breather (AB) and its M-breather generalisation, hereafter called AB
M
, are exact solutions of the focusing NLS equation periodic in space and exponentially localised in time over the constant unstable background; they describe the appearance of M unstable nonlinear modes and their interaction, and they are expected to play a relevant role in the theory of periodic anomalous (rogue) waves in nature. It is therefore important to establish the stability properties of these solutions under perturbations. Concerning perturbations of these solutions within the NLS dynamics, there is the following common belief in the literature. Let the NLS background be unstable with respect to the first N modes; then (i) if the M unstable modes of the AB
M
solution are strictly contained in this set (M < N), then the AB
M
is unstable; (ii) if they coincide with this set (M = N), then the AB
M
solution is neutrally stable. In this paper we argue instead that the AB
M
solution is always linearly unstable, even in the saturation case M = N, and we prove it in the simplest case M = N = 1, constructing two examples of x-periodic solutions of the linearised theory growing exponentially in time. Then we sketch the proof of completeness of the basis of periodic solutions of the linearised theory. We also investigate the nonlinear instability showing that (i) a perturbed AB initial condition evolves into a recurrence of ABs; (ii) the AB solution is more unstable than the background solution, and its instability increases as T → 0, where T is the AB appearance time. Although the AB solution is linearly and nonlinearly unstable, its instability generates a recurrence of ABs, and this recurrence implies its relevance in the natural phenomena described by the NLS equation, as well as its orbital stability, using a specific definition of orbital stability present in the literature.
Fibro-CoSANet: pulmonary fibrosis prognosis prediction using a convolutional self attention network
Authors: Al Nazi Zabir , Rabbi Mashrur Fazla , Islam Md Amirul , Saha Shumit 
Published: November 2021

Abstract
Idiopathic pulmonary fibrosis (IPF) is a restrictive interstitial lung disease that causes lung function decline by lung tissue scarring. Although lung function decline is assessed by the forced vital capacity (FVC), determining the accurate progression of IPF remains a challenge. To address this challenge, we proposed Fibro-CoSANet, a novel end-to-end multi-modal learning based approach, to predict the FVC decline. Fibro-CoSANet utilized computed tomography images and demographic information in convolutional neural network frameworks with a stacked attention layer. Extensive experiments on the OSIC Pulmonary Fibrosis Progression Dataset demonstrated the superiority of our proposed Fibro-CoSANet by achieving new state-of-the-art modified Laplace log-likelihood score of −6.68. This network may benefit research areas concerned with designing networks to improve the prognostic accuracy of IPF. The source-code for Fibro-CoSANet is available at: https://github.com/zabir-nabil/Fibro-CoSANet.
A novel preform compaction method for fabricating high-performance Y–Ba–Cu–O single-grain bulk superconductor
Authors: Li Guo-Zheng , Wang Miao 
Published: November 2021

Abstract
A novel preform compaction method based on one new type of divisible mould was employed for fabricating single-grain YBCO bulk superconductor, which can complete the preform demoulding process through opening of the mould, rather than pushing the preform out in the regular mould. Thus it has natural superiority on eliminating macro-cracks, which has been proved by the sample surface morphology and the trapped field characterization. In addition, the divisible mould pressed sample exhibits higher levitation force and trapped field properties than the regular mould pressed samples, verifying the potentials of the divisible mould on improving the bulk performance. The optical micrograph results prove the superiority of the divisible mould on eliminating tiny cracks on sample surface. The processing facility and sample reliability brought by the divisible mould should also be emphasized, because the crushing and re-pressing of preform when it presents visible cracks can be omitted and the failed samples with surface cracks will no longer appear. Consequently, the experimental efficiency and stability are both enhanced.
An overview of structured illumination microscopy: recent advances and perspectives
Authors: Samanta Krishnendu , Joseph Joby 
Published: November 2021

AbstractStructured illumination microscopy (SIM) is one of the most significant widefield super-resolution optical imaging techniques. The conventional SIM utilizes a sinusoidal structured pattern to excite the fluorescent sample; which eventually down-modulates higher spatial frequency sample information within the diffraction-limited passband of the microscopy system and provides around two-fold resolution enhancement over diffraction limit after suitable computational post-processing. Here we provide an overview of the basic principle, image reconstruction, technical development of the SIM technique. Nonetheless, in order to push the SIM resolution further towards the extreme nanoscale dimensions, several different approaches are launched apart from the conventional SIM. Among the various SIM methods, some of the important techniques e.g. TIRF, non-linear, plasmonic, speckle SIM etc are discussed elaborately. Moreover, we highlight different implementations of SIM in various other imaging modalities to enhance their imaging performances with augmented capabilities. Finally, some future outlooks are mentioned which might develop fruitfully and pave the way for new discoveries in near future.

Abstract
The layered transition metal dichalcogenides (TMDs) exhibit the intriguing physical properties and potential application in novel electronic devices. However, controllable growth of multilayer TMDs remains challenging. Herein, large-scale and high-quality multilayer prototype TMDs of W(Mo)Se2 were synthesized via chemical vapor deposition. For Raman and photoluminescence measurements, 2H and 3R multilayer WSe2 crystals displayed significant layer-dependent peak position and intensity feature. Besides, different from the oscillatory relationship of second harmonic generation (SHG) intensity for odd–even layer numbers in 2H-stacked multilayer WSe2, the SHG intensity of 3R-stacked ones parabolically increased with the thickness due to the absence of inversion symmetry. For device application, photodetectors based on WSe2 with increasing thickness exhibited p-type (bilayer), ambipolar (trilayer), and n-type (four layers) semiconductor behaviors, respectively. Furthermore, photodetectors based on the as-synthesized 3R-stacked WSe2 flakes displayed an excellent responsivity of 7.8 × 103 mA W−1, high specific detectivity (Da*) of 1.7 × 1014 Jones, outstanding external quantum efficiency of 8.6 × 102%, and fast response time (τ
Rise = 57 ms and τ
Fall = 53 ms) under 532 nm illumination with bias voltage of V
ds = 5 V. Similar results have also been achieved in multilayer MoSe2 crystals. All these findings indicate great potential of 3R-stacked TMDs in two-dimensional optoelectronic applications.

Published: November 2021

Abstract

Purpose
The primary aim of this study was to investigate the accuracy of the volumetric method for intravenous (IV) preparations and explore the utility of gravimetric methods in the medication preparation process within multiple institutions. Secondary outcomes of this study were syringe size percent variations and impact on drug expenditures.

Methods
A prospective, noninterventional, multisite study was conducted between March 2015 and December 2016 to generate baseline estimates of accuracy and precision in the volumetric medication preparation process. Five hospitals in the United States were recruited for study participation. During the data collection process, technicians were required to measure the syringe at 3 different points: when the new empty syringe was connected to a closed-system transfer device (CSTD), when the filled syringe containing the prepared dose of medication was connected to a CSTD, and when the used syringe with residual medication was connected to a CSTD. The actual dose of drug dispensed (in mg) was divided by the specific gravity of the medication to determine the actual volume of medication dispensed.

Results
A total of 4,443 compounded sterile products representing 60 medications across 5 hospitals were eligible for the study. Of the evaluated preparations, 91.92% were within 5% of the prescribed dose and 96.56% were within 10% of the prescribed dose. The outliers ranged from –144.10% to 233.72%.

Conclusion
The potential for significant over- and undertreatment of an individual patient receiving IV chemotherapy exists, indicating the need for an additional measurement method, such as real-time gravimetric verification, to ensure an accurate dose is administered to every patient.
Kletzer’s Direttissima
Authors: Simmonds N E 
Published: November 2021

Abstract
Kletzer believes that, by focusing upon permission, we can derive the law’s obligatory power from the idea that the world is normatively inert. In a normatively inert world, everything is permitted. Consequently, if the law operates by permitting the use of force, it requires no deep normative underpinning: it could even invoke moral nihilism as its basis. Although ingenious, this argument faces two formidable problems. Firstly, in a normatively inert world, permissions can have causal effects but no normative effects. And secondly, the normatively inert world cannot be assumed as an uncontentious given or derived from the shortfall between what is and what ought to be, as Kletzer supposes. It requires a contestable metaphysics. Although accepting the unity of practical reason, Kletzer rejects the traditional natural law position on the grounds that law and morality are of dissimilar form, so that law cannot be grounded in morality. At the same time, he fails to offer any explanation of that difference in form. Once we have a satisfactory explanation of this difference, we see that it is precisely the difference in form between law and morality that enables us to understand law’s basis in morality. Individual moral engagement and reflection can flourish only within communities governed by law.
Market-Based Monetary Policy Uncertainty
Authors: Bauer Michael D , Lakdawala Aeimit , Mueller Philippe 
Published: November 2021

Abstract
Uncertainty about future policy rates plays a crucial role for the transmission of monetary policy to financial markets. We demonstrate this using event studies of FOMC announcements and a new model-free uncertainty measure based on derivatives. Over the ‘FOMC uncertainty cycle’ announcements systematically resolve uncertainty, which then gradually ramps up again. Changes in monetary policy uncertainty around FOMC announcements—often due to forward guidance—have pronounced effects on asset prices that are distinct from the effects of conventional policy surprises. The level of uncertainty determines the magnitude of financial market reactions to surprises about the path of policy rates.
The relevance logic of Boolean groups
Authors: Weiss Yale 
Published: November 2021

AbstractIn this article, I consider the positive logic of Boolean groups (i.e. Abelian groups where every non-identity element has order 2), where these are taken as frames for an operational semantics à la Urquhart. I call this logic BG. It is shown that the logic over the smallest nontrivial Boolean group, taken as a frame, is identical to the positive fragment of a quasi-relevance logic that was developed by Robles and Méndez (an extension of this result where negation is included is also discussed). It is proved that BG satisfies the variable sharing property and is Halldén complete, while failing to satisfy the disjunction property. Sound and complete subscripted tableaux are presented for BG. An axiomatization (in the positive language extended with fusion) is presented, which is sound with respect to BG and, with respect to a related ternary relational semantics, complete; the problem of identifying a complete axiomatization for BG itself is left open. Connections between BG and the quasi-relevance logic KR are also discussed.
Capsaicin restores sodium iodine symporter-mediated radioiodine uptake through bypassing canonical TSH‒TSHR pathway in anaplastic thyroid carcinoma cells

Published: November 2021

Abstract
Anaplastic thyroid cancer (ATC) is a rare but highly lethal disease. ATCs are resistant to standard therapies and are extremely difficult to manage. The stepwise cell dedifferentiation results in the impairment of the iodine-metabolizing machinery and the infeasibility of radioiodine treatment in ATC. Hence, reinducing iodine-metabolizing gene expression to restore radioiodine avidity is considered as a promising strategy to fight against ATC. In the present study, capsaicin (CAP), a natural potent transient receptor potential vanilloid type 1 (TRPV1) agonist, was discovered to reinduce ATC cell differentiation and to increase the expression of thyroid transcription factors (TTFs including TTF-1, TTF-2, and PAX8) and iodine-metabolizing proteins, including thyroid-stimulating hormone receptor (TSHR), thyroid peroxidase, and sodium iodine symporter (NIS), in two ATC cell lines, 8505C and FRO. Strikingly, CAP treatment promoted NIS glycosylation and its membrane trafficking, resulting in a significant enhancement of radioiodine uptake of ATC cells in vitro. Mechanistically, CAP-activated TRPV1 channel and subsequently triggered Ca2+ influx, cyclic adenosine monophosphate (cAMP) generation, and cAMP-responsive element-binding protein (CREB) signal activation. Next, CREB recognized and bound to the promoter of SLC5A5 to facilitate its transcription. Moreover, the TRPV1 antagonist CPZ, the calcium chelator BAPTA, and the PKA inhibitor H-89 effectively alleviated the redifferentiation exerted by CAP, demonstrating that CAP might improve radioiodine avidity through the activation of the TRPV1‒Ca2+/cAMP/PKA/CREB signaling pathway. In addition, our study indicated that CAP might trigger a novel cascade to redifferentiate ATC cells and provide unprecedented opportunities for radioiodine therapy in ATC, bypassing canonical TSH‒TSHR pathway.
The regulatory subunits of PI3K, p85α and p85β, differentially affect BRD7-mediated regulation of insulin signaling
Authors: Lee Junsik M , Liu Renyan , Park Sang Won 
Published: November 2021

Abstract
Bromodomain-containing protein 7 (BRD7) has been shown to interact with the regulatory subunit of phosphatidylinositol 3-kinase (PI3K), p85, in the insulin signaling pathway. Here, we show that upregulation of hepatic BRD7 improves glucose homeostasis even in the absence of either p85 isoform, p85α or p85β. However, BRD7 leads to differential activation of downstream effector proteins in the insulin signaling pathway depending on which isoform of p85 is present. In the presence of only p85α, BRD7 overexpression increases phosphorylation of insulin receptor (IR) upon insulin stimulation, without increasing the recruitment of p85 to IR substrate. Overexpression of BRD7 also increases activation of Akt in response to insulin, but does not affect basal phosphorylation levels of Akt. Meanwhile, the phosphorylation of glycogen synthase kinase 3β (GSK3β) is increased by overexpression of BRD7. On the other hand, in the presence of only p85β, BRD7 overexpression does not affect phosphorylation levels of IR, and Akt phosphorylation is not affected by insulin stimulation following BRD7 upregulation. However, BRD7 overexpression leads to increased basal phosphorylation levels of Akt and GSK3β. These data demonstrate that BRD7’s action on glucose homeostasis does not require the presence of both p85 isoforms, and p85α and p85β have unique roles in insulin signaling in the liver.
Questionable and Open Research Practices: Attitudes and Perceptions among Quantitative Communication Researchers
Authors: Bakker Bert N , Jaidka Kokil , Dörr Timothy , Fasching Neil , Lelkes Yphtach 
Published: November 2021

Abstract
Recent contributions have questioned the credibility of quantitative communication research. While questionable research practices (QRPs) are believed to be widespread, evidence for this belief is, primarily, derived from other disciplines. Therefore, it is largely unknown to what extent QRPs are used in quantitative communication research and whether researchers embrace open research practices (ORPs). We surveyed first and corresponding authors of publications in the top-20 journals in communication science. Many researchers report using one or more QRPs. We find widespread pluralistic ignorance: QRPs are generally rejected, but researchers believe they are prevalent. At the same time, we find optimism about the use of open science practices. In all, our study has implications for theories in communication that rely upon a cumulative body of empirical work: these theories are negatively affected by QRPs but can gain credibility if based upon ORPs. We outline an agenda to move forward as a discipline.
The philosophical interpretation of language game theory
Authors: Zangwill Nick 
Published: November 2021

AbstractI give an informal presentation of the evolutionary game theoretic approach to the conventions that constitute linguistic meaning. The aim is to give a philosophical interpretation of the project, which accounts for the role of game theoretic mathematics in explaining linguistic phenomena. I articulate the main virtue of this sort of account, which is its psychological economy, and I point to the casual mechanisms that are the ground of the application of evolutionary game theory to linguistic phenomena. Lastly, I consider the objection that the account cannot explain predication, logic, and compositionality.
Non-invertible topological defects in 4-dimensional $\mathbb {Z}_2$ pure lattice gauge theory
Authors: Koide Masataka , Nagoya Yuta , Yamaguchi Satoshi 
Published: November 2021

Abstract
We explore topological defects in the 4D pure $\mathbb {Z}_2$ lattice gauge theory. This theory has 1-form $\mathbb {Z}_{2}$ center symmetry as well as Kramers–Wannier–Wegner (KWW) duality. We construct the KWW duality topological defects in a similar way to those constructed by Aasen et al. [J. Phys. A 49, 354001 (2016)] for the 2D Ising model. These duality defects turn out to be non-invertible. We also construct 1-form $\mathbb {Z}_{2}$ symmetry defects as well as the junctions between the KWW duality defects and 1-form $\mathbb {Z}_{2}$ center symmetry defects. The crossing relations between these defects are derived. The expectation values of some configurations of these topological defects are calculated by using these crossing relations.

Abstract

Objectives
We evaluated the impact of type 2 diabetes mellitus (T2DM) on RA treatment and outcomes in a longitudinal RA cohort.

Methods
We analysed data collected in the period 2001–2013 involving 583 RA patients, including demographics, diabetes diagnosis, clinical features, treatment, ACR functional class, HAQ, and quality-of-life measurement using the Short-Form 36.

Results
Seventy-seven (13.2%) of the RA patients had T2DM. DAS28 was not different in patients with T2DM at 5 years post-RA diagnosis. Fewer T2DM patients received MTX than those without T2DM (51% vs 80%, P &lt; 0.001). Using univariate analysis, T2DM patients were more likely to experience poorer outcomes in terms of ACR functional status (P = 0.009), joint surgery (P = 0.007), knee arthroplasty (P &lt; 0.001) and hospital admissions (P = 0.006). Multivariate regression analyses showed more knee arthroplasty (P = 0.047) in patients with T2DM.

Conclusion
Fewer patients with T2DM received MTX compared with those without T2DM. Patients with RA and T2DM were at higher risk of knee arthroplasty than RA patients without T2DM.
