Published: May 2023

AbstractSevere acute respiratory syndrome coronavirus‐2 (SARS‐CoV‐2) is responsible for coronavirus disease of 2019 (COVID‐19) that infected more than 760 million people worldwide with over 6.8 million deaths to date. COVID‐19 is one of the most challenging diseases of our times due to the nature of its spread, its effect on multiple organs, and an inability to predict disease prognosis, ranging from being completely asymptomatic to death. Upon infection, SARS‐CoV‐2 alters the host immune response by changing host‐transcriptional machinery. MicroRNAs (miRNAs) are regarded as post‐transcriptional regulators of gene expression that can be perturbed by invading viruses. Several in vitro and in vivo studies have reported such dysregulation of host miRNA expression upon SARS‐CoV‐2 infection. Some of this could occur as an anti‐viral response of the host to the viral infection. Viruses themselves can counteract that response by mounting their own pro‐viral response that facilitates virus infection, an aspect which may cause pathogenesis. Thus, miRNAs could serve as possible disease biomarkers in infected people. In the current review, we have summarised and analysed the existing data about miRNA dysregulation in patients infected with SARS‐CoV‐2 to determine their concordance between studies, and identified those that could serve as potential biomarkers during infection, disease progression, and death, even in people with other co‐morbidities. Having such biomarkers can be vital in not only predicting COVID‐19 prognosis, but also the development of novel miRNA‐based anti‐virals and therapeutics which can become invaluable in case of the emergence of new viral variants with pandemic potential in the future.

Published: May 2023

AbstractIn recent years, unmanned aerial vehicles (UAVs) have been confirmed as a powerful tool for countless applications in nearly every industry, in which collision avoidance plays a vital role for micro aerial vehicles (MAVs) performing autonomous missions. The complexity of collision avoidance systems is directly related to the complexity of the navigation environment, the avoidance of highly uncertain obstacles being a more thoroughly researched critical aspect. The non‐cooperative collision avoidance strategy is necessary when communication between the agents is unavailable, under the case with many existing passive obstacles and non‐cooperative flying objects. In this article, we review the topic of non‐cooperative collision avoidance for MAVs in dynamic environments by covering two main issues: onboard sensing and obstacle description algorithms. A detailed discussion of these two topics is provided to face non‐cooperative collision avoidance technology for MAVs. Finally, the paper summarizes the open challenges and foreseen future directions in this field.
Striving for sustainable development: The impact of corporate social responsibility on corporate performance of Chinese manufacturing multinationals in Africa
Authors: Zhang Qiaowen , de Vries Annalien 
Published: May 2023

AbstractThe Forum of China‐Africa Cooperation benefits both China and Africa in tackling development issues. Increased foreign direct investment from China can specifically help to reduce Africa's struggles to meet its 2030 sustainable development goals. Due to insufficient global investment experience and stigmatization, Chinese multinational companies (MNCs) often experience unsatisfactory corporate performance in host countries. A successful strategy to mitigate stigma and be perceived by stakeholders as “legitimate” is through corporate social responsibility (CSR) engagement. Exploring how Chinese MNCs in Africa can achieve desirable corporate performance through CSR engagement is important to promote mutual benefits for both Chinese MNCs and African societies. This study aimed to contribute to emerging market CSR literature by examining the relationship between CSR engagement and corporate performance of Chinese manufacturing MNCs operating in Africa, with emphasis on moral legitimacy as a mediating factor and institutional distance as a moderating factor. Survey data were collected between June 2019 and January 2020 from a sample of 203 Chinese manufacturing MNCs subsidiaries in Africa. By using hierarchical regression and bootstrapping, we find that the positive relationship between CSR engagement and corporate performance is fully mediated by moral legitimacy gaining. This mediation effect is moderated by institutional distance. The results enrich our understanding of how Chinese manufacturing MNCs' corporate performance can be enhanced by addressing social challenges and promoting sustainable investment cooperation with African countries. These results are important for Chinese MNCs and authorities, as well as African public authorities when designing policies to promote China‐Africa sustainable investment cooperation.
Strategic or substantive innovation? The effect of government environmental punishment on enterprise green technology innovation

Published: May 2023

AbstractUnder the conduction of decentralized environmental governance, environmental punishment has become a pivotal complementary tool for local government environment management and an intuitive reflection of governance efficiency. However, the literature concerning the effect of local government environmental punishment towards the green technology innovation of enterprises is void. To bridge this gap, this paper adopts the fixed‐effect model to investigate the impact of government environmental punishment on green technology innovation based on the data of China's A‐share listed enterprises from 2010 to 2020. The study finds that the punishment can significantly promote enterprises' green technology innovation. The distinction between the type of innovation reveals that environmental punishment promotes substantive green technology innovation of enterprises, while the effect on strategic green technology innovation is not significant. As far as the influence path is concerned, external pressure and internal incentive are both important mechanisms for environmental punishment to facilitate the green technology innovation of enterprises. Heterogeneity analysis demonstrates that the positive effect of punishment on green technology innovation is more prominent in non‐state‐owned enterprises, heavily polluting industries and regions with strong public awareness of environmental protection. Further discussion reveals that the facilitative effect of punishment on green technology innovation also significantly improves the environmental performance of enterprises. This paper not only confirms the positive role of government intervention in environmental protection, but also provides practical reference for how to improve enterprises' competitiveness.

AbstractWater electrolysis is an ideal method for industrial green hydrogen production. However, due to increasing scarcity of freshwater, it is inevitable to develop advanced catalysts for electrolyzing seawater especially at large current density. This work reports a unique Ru nanocrystal coupled amorphous‐crystal Ni(Fe)P2 nanosheet bifunctional catalyst (Ru‐Ni(Fe)P2/NF), caused by partial substitution of Fe to Ni atoms in Ni(Fe)P2, and explores its electrocatalytic mechanism by density functional theory (DFT) calculations. Owing to high electrical conductivity of crystalline phases, unsaturated coordination of amorphous phases, and couple of Ru species, Ru‐Ni(Fe)P2/NF only requires overpotentials of 375/295 and 520/361 mV to drive a large current density of 1 A cm−2 for oxygen/hydrogen evolution reaction (OER/HER) in alkaline water/seawater, respectively, significantly outperforming commercial Pt/C/NF and RuO2/NF catalysts. In addition, it maintains stable performance at large current density of 1 A cm−2 and 600 mA cm−2 for 50 h in alkaline water and seawater, respectively. This work provides a new way for design of catalysts toward industrial‐level seawater splitting.
A Unique Etching‐Doping Route to Fe/Mo Co‐Doped Ni Oxyhydroxide Catalyst for Enhanced Oxygen Evolution Reaction

Published: May 2023

AbstractFe‐doped Ni (oxy)hydroxide shows intriguing activity toward oxygen evolution reaction (OER) in alkaline solution, yet it remains challenging to further boost its performance. In this work, a ferric/molybdate (Fe3+/MoO42−) co‐doping strategy is reported to promote the OER activity of Ni oxyhydroxide. The reinforced Fe/Mo‐doped Ni oxyhydroxide catalyst supported by nickel foam (p‐NiFeMo/NF) is synthesized via a unique oxygen plasma etching‐electrochemical doping route, in which precursor Ni(OH)2 nanosheets are first etched by oxygen plasma to form defect‐rich amorphous nanosheets, followed by electrochemical cycling to trigger simultaneously Fe3+/MoO42− co‐doping and phase transition. This p‐NiFeMo/NF catalyst requires an overpotential of only 274 mV to reach 100 mA cm−2 in alkaline media, exhibiting significantly enhanced OER activity compared to NiFe layered double hydroxide (LDH) catalyst and other analogs. Its activity does not fade even after 72 h uninterrupted operation. In situ Raman analysis reveals that the intercalation of MoO42− is able to prevent the over‐oxidation of NiOOH matrix from β to γ phase, thus keeping the Fe‐doped NiOOH at the most active state.

Published: May 2023

AbstractThe development of low platinum‐based alloy electrocatalysts is crucial to accelerate the commercialization of fuel cells, yet remains a synthetic challenge and an incompatibility between activity and stability. Herein, a facile procedure to fabricate a high‐performance composite that comprises Pt–Co intermetallic nanoparticles (IMNs) and Co, N co‐doped carbon (Co‐N‐C) electrocatalyst is proposed. It is prepared by direct annealing of homemade carbon black‐supported Pt nanoparticles (Pt/KB) covered with a Co‐phenanthroline complex. During this process, most of Co atoms in the complex are alloyed with Pt to form ordered Pt–Co IMNs, while some Co atoms are atomically dispersed and doped in the framework of superthin carbon layer derived from phenanthroline, which is coordinated with N to form Co–Nx moieties. Moreover, the Co‐N‐C film obtained from complex is observed to cover the surface of Pt–Co IMNs, which prevent the dissolution and agglomeration of nanoparticles. The composite catalyst exhibits high activity and stability toward oxygen reduction reactions (ORR) and methanol oxidation reactions (MOR), delivering outstanding mass activities of 1.96 and 2.92 A mgPt−1 for ORR and MOR respectively, owing to the synergistic effect of Pt–Co IMNs and Co‐N‐C film. This study may provide a promising strategy to improve the electrocatalytic performance of Pt‐based catalysts.
Performance Improvement of Lead‐Based Halide Perovskites through B‐Site Ion‐Doping Strategies
Authors: Bian Liukang , Cao Fengren , Li Liang 
Published: May 2023

AbstractOwing to their excellent properties, lead halide perovskites have attracted extensive attention in the photoelectric field. Presently, the certified power conversion efficiency of perovskite solar cells has reached 25.7%, the specific detectivity of perovskite photodetectors has exceeded 1014 Jones, and the external quantum efficiency of perovskite‐based light‐emitting diode has exceeded 26%. However, their practical applications are limited by the inherent instability induced by the perovskite structure due to moisture, heat, and light. Therefore, one of the widely used strategies to address the issue is to replace partial ions of the perovskites with ions of smaller radii to shorten the bond length between halides and metal cations, improving the bond energy and enhancing the perovskite stability. Particularly, the B‐site cation in the perovskite structure can affect the size of eight cubic octahedrons and their gap. However, the X‐site can only affect four such voids. This review comprehensively summarizes the recent progress in B‐site ion‐doping strategies for lead halide perovskites and provides some perspectives for further performance improvements.
Investigation of the effect of trapezoidal infill plate angle on the behavior of the corrugated steel shear walls – An experimental and numerical study
Authors: Hosseinzadeh Leila , Ghamari Ali 
Published: May 2023

AbstractStudies on corrugated steel shear walls (CSSWs) generally indicate a noticeable increase in energy absorption, as well as an increasing shear buckling capacity of corrugated plates more than the flat plates. In this article, the effect of changing the angle of the trapezoidal panel on the behavior of CSSWs has extensively been investigated. Three specimens of CSSW with one story and single bay in half‐scale are tested under cyclic load. Gravity loads are not applied at the top of the walls; however, the horizontal load has been applied at the top of each specimen. The loading sequence has been implemented through “displacement control” with increasing and decreasing amplitudes. The observations of the experiment do indicate that stress concentration has been increased in the corner of subpanels, by increasing the corrugation angle. Also, the stiffness and energy dissipation are getting decreased, by growing the corrugation angle. Investigating the numerical models has been showing that in CSSW, seismic factors are affected by corrugation angle; however, varying parameters against changing angles do not show any reasonable relationship. The obtained results of investigating the effect of surrounding frame stiffness variation on the behavior of walls have also been indicating that increasing frame stiffness shall not be leading to improving all seismic parameters.
A new fib Model Code proposal for a beam‐end type bond test
Authors: Metelli Giovanni , Cairns John , Plizzari Giovanni 
Published: May 2023

AbstractA beam‐end test is proposed in this paper and in the new fib Model Code 2020 to determine the effects of concrete type, confinement effects, and casting position on the anchorage strength of reinforcing bars. Two bars are cast in each specimen (in the two opposite corners), one in a “good” casting position and the other in “poor” casting position. The proposed test aims to be an economical bond test capable to represent actual conditions of anchored bars in real design practice. The test is also intended to verify whether existing provisions for bond and anchorage in the fib Model Code are suitable in nonconventional concrete. The validity of the proposed beam end type bond test is assessed by the results of more 60 tests on rebars having anchorage length of about 20 times the bar diameter in plain concrete, in fiber reinforced concrete, and in recycled aggregate concrete. Experimental results provide information both on the “top cast effect” in three types of concrete and on the effectiveness of fib Model Code provisions for anchorage when nonconventional concrete is used.

Published: May 2023

AbstractA 12‐year‐old, neutered, male Jack Russell terrier was diagnosed with a disseminated intramuscular anaplastic round cell tumour with primary hepatic, splenic, subcutaneous and medullary involvement. The tumour was confirmed by histopathology, immunohistochemistry and polymerase chain reaction analysis of antigen receptor gene rearrangements to be of plasma cell origin. Tumour cells were lambda light chain‐positive, multiple myeloma 1‐positive and pan‐B marker‐negative (paired box protein 5, CD20 and CD79) and showed clonal immunoglobulin heavy chain gene rearrangement. Computed tomography did not identify osteolytic lesions. Plasma cells represented 14% of bone marrow cells. Serum and urine electrophoresis were not performed because of a normal serum globulin concentration. To the authors’ knowledge, this is the first case report describing a disseminated diffuse intramuscular anaplastic plasma cell tumour in a dog without evidence of multiple myeloma on initial presentation or progression to multiple myeloma or plasma cell leukaemia during follow‐up.
Contribution of three‐dimensional printed models to neurosurgery: Description of a feline intracranial meningioma treated by rostrotentorial craniectomy
Authors: Daval Julien , Guillemot Alexandre , Dutil Guillaume , Testault Isabelle 
Published: May 2023

AbstractA 10‐year‐old, male, neutered, domestic shorthair cat with generalised tonic‐clonic seizures was suspected of parietal meningioma. After segmentation from computed tomography images, real‐scale three‐dimensional prints of the skull and tumour were made using stereolithography. Intraoperative use of this model enabled identification of the craniectomy margins and exposed suitable tumour edges. Debulking was straightforward with no serious complications such as severe haemorrhage or untreatable cerebral oedema. Recovery was uneventful, and the cat showed normal neurological status postoperatively. Based on histopathological findings, a meningioma was confirmed. This is the first report of a three‐dimensional printed resin anatomic model of the skull with an intracranial tumour in companion animals. Such three‐dimensional prints are easily designed, inexpensive and accurate tools to study anatomic features of the patient and improve surgical procedures. The simple three‐dimensional printed replica presented here is a starting point for more detailed prints and extended applications such as craniectomy and cranioplasty procedures in veterinary neurosurgery.
Simultaneous CTEQ-TEA extraction of PDFs and SMEFT parameters from jet and $$ t\overline{t} $$ data

Published: May 2023

Abstract
Recasting phenomenological Lagrangians in terms of SM effective field theory (SMEFT) provides a valuable means of connecting potential BSM physics at momenta well above the electroweak scale to experimental signatures at lower energies. In this work we jointly fit the Wilson coefficients of SMEFT operators as well as the PDFs in an extension of the CT18 global analysis framework, obtaining self-consistent constraints to possible BSM physics effects. Global fits are boosted with machine-learning techniques in the form of neural networks to ensure efficient scans of the full PDF+SMEFT parameter space. We focus on several operators relevant for top-quark pair and jet production at hadron colliders and obtain constraints on the Wilson coefficients with Lagrange Multiplier scans. We find mild correlations between the extracted Wilson coefficients, PDFs, and other QCD parameters, and see indications that these correlations may become more prominent in future analyses based on data of higher precision. This work serves as a new platform for joint analyses of SM and BSM physics based on the CTEQ-TEA framework.
Goldstone bosons and fluctuating hydrodynamics with dipole and momentum conservation
Authors: Glorioso Paolo , Huang Xiaoyang , Guo Jinkang , Rodriguez-Nieva Joaquin F. , Lucas Andrew 
Published: May 2023

Abstract
We develop a Schwinger-Keldysh effective field theory describing the hydrodynamics of a fluid with conserved charge and dipole moments, together with conserved momentum. The resulting hydrodynamic modes are highly unusual, including sound waves with quadratic (magnon-like) dispersion relation and subdiffusive decay rate. Hydrodynamics itself is unstable below four spatial dimensions. We show that the momentum density is, at leading order, the Goldstone boson for a dipole symmetry which appears spontaneously broken at finite charge density. Unlike an ordinary fluid, the presence or absence of energy conservation qualitatively changes the decay rates of the hydrodynamic modes. This effective field theory naturally couples to curved spacetime and background gauge fields; in the flat spacetime limit, we reproduce the “mixed rank tensor fields” previously coupled to fracton matter.
Boundary Symmetry Breaking in CFT and the string order parameter
Authors: Bonsignori Riccarda , Capizzi Luca , Panopoulos Pantelis 
Published: May 2023

AbstractWe consider the ground state of a one-dimensional critical quantum system carrying a global symmetry in the bulk, which is explicitly broken by its boundary conditions. We probe the system via a string-order parameter, showing how it detects the symmetry breaking pattern. We give a precise characterization of the mechanism depicted above in Boundary CFT, and we find a general logarithmic scaling for the order parameter. As a first example we analyze the breaking of a U(1) symmetry for complex free theories induced by a boundary pairing term. Moreover, we give predictions for the breaking of U(N) in free theories, arising from a boundary mixing. We test our predictions with numerical calculations for some lattice realizations of free fermionic system with boundary symmetry breaking, finding a good agreement.
Blowup equations for little strings
Authors: Kim Hee-Cheol , Kim Minsung , Sugimoto Yuji 
Published: May 2023

Abstract
We propose blowup equations for 6d little string theories which generalize Nakajima-Yoshioka’s blowup equations for the 4d/5d instanton partition functions on Omega background. We find that unlike the blowup equations for standard SQFTs, we need to sum over auxiliary magnetic fluxes on the blown-up ℙ1 for a non-dynamical 2-form gauge field which plays a role in canceling the mixed anomalies of the gauge symmetries. We demonstrate with explicit examples that the blowup equations, when combined with the modular properties, can be solved in order to determine the elliptic genera of little strings.
Post-inflationary axions: a minimal target for axion haloscopes
Authors: Gorghetto Marco , Hardy Edward 
Published: May 2023

Abstract
An axion-like-particle (ALP) in the post-inflationary scenario with domain wall number N > 1 can be dark matter if the residual ℤN symmetry has a small explicit breaking. Although we cannot determine the full dynamics of the system reliably, we provide evidence that such an ALP can account for the observed dark matter abundance while having a relatively small decay constant and consequently a possibly large coupling to photons. In particular, we determine the number of domain walls per Hubble patch around the time when they form using numerical simulations and combine this with analytic expectations about the subsequent dynamics. We show that the strongest constraint on the decay constant is likely to come from the dark matter ALPs being produced with large isocurvature fluctuations at small spatial scales. We also comment on the uncertainties on the dark matter small-scale structure that might form from these overdensities, in particular pointing out the importance of quantum pressure in the N = 1 case.
