The COVID-19 pandemics and import demand elasticities: evidence from China’s customs data
Authors: Zhang Weikang , Yan Isabel K. M. , Cheung Yin-Wong 
Published: December 2023

AbstractWe study China’s import demand elasticities using HS 8-digit customs data on China’s provincial imports during January 2019 to March 2021. It is found that both direct bilateral exchange rate elasticity and third-country exchange rate elasticity are affected by (1) policies that these Asian economies adopted to alleviate the adverse impacts of the COVID-19 pandemic and (2) the degree of concentration of exporters exporting a certain product to a certain Chinese provincial market. It is found that economic support policies will lower the bilateral exchange rate elasticity of trade flows, or even alter the sign of the bilateral exchange rate elasticity of China’s imports. Besides, the economic support policies can alleviate the pressure of foreign competition on exporters and make the exporters more resilient to the impacts of foreign competitors’ exchange rate depreciation. In contrast, the degree of market concentration of exporters in a certain provincial market affects the exchange rate and the third-country exchange rate elasticity differently. A higher market concentration lowers the bilateral exchange rate elasticity of trade flows but magnifies the impact of foreign competitors’ currency depreciation on exporters. These results are robust to alternative modes of trade, regional heterogeneity, product heterogeneity, various measures of policy responses to the pandemic, and alternative database.
A universal method for constructing n-dimensional polynomial hyperchaotic systems with any desired positive Lyapunov exponents
Authors: Yan Wenhao , Ding Qun 
Published: December 2023

Abstract
Most existing chaotic maps have many defects in engineering applications, such as discontinuous parameter range, uneven output of chaotic sequences and dynamic degradation. Based on this, a generalized n-dimensional polynomial chaotic map is proposed in this paper. By setting the coefficient of the linear term and the order of the highest order term of the polynomial, a series of n-dimensional polynomial chaotic maps of specific Lyapunov exponents can be obtained. The system solves the defects of the above system well, in addition, one can get the desired number of positive Lyapunov exponents, and one can get the desired value of positive Lyapunov exponents. Then, the effectiveness of the map is verified by a specific numerical example, and its dynamic analysis shows that the map has complex dynamic behavior. Finally, the map is applied to secure communication technology. Compared with other chaotic maps of the same dimension, the maps can obtain a smaller bit error rate, indicating that the chaotic map is more suitable for chaotic secure communication applications.

Published: December 2023

Abstract
In most animal and plant cells, the information’s processing is insured by calcium ions. This contribution studies the global dynamics of a model of calcium oscillation. From the stability analysis, it is found that the oscillations of that model are self-excited since they are generated from unstable equilibria. Using two-parameter charts, the general behavior of the model is explored. From the hysteresis analysis using bifurcation diagrams with their related Largest Lyapunov Exponent (LLE) graphs, the coexisting oscillation modes are recorded. This phenomenon is characterized by the simultaneous existence of periodic and chaotic oscillations in the considered model by just varying the initial conditions. Using a set of parameters for which the model exhibits multistability, the basins of attraction related to each coexisting solution are computed and enable the capture of any coexisting pattern.
Synchronization of complexity enhanced chaos in semiconductor lasers

Published: December 2023

Abstract
In synchronized chaotic lasers based secure key distribution and other encrypted communications, presence of the time delay signature in chaos poses a threat to security. So the transmitter and receiver lasers should preferably be operated in complexity enhanced chaotic regime where the time delay signature is hidden. However, achieving good synchronization in experiments in such regime is challenging. We report experimental demonstration of achieving excellent synchronization between two semiconductor lasers even when both the lasers are operating in complexity enhanced chaotic regime with absolutely no time delay signature present in their output. This chaotic regime is ensured by evaluating the auto correlation function, permutation entropy and spectrum analysis of the time series. As a measure of synchronization, cross-correlation coefficient of 0.923 is achieved between the transmitter and receiver lasers. This results are of immense importance in chaos based secure key distribution and other encrypted communication schemes.
Energy function and complex dynamics from a jerk system
Authors: Yu Jinhua , Njitacke Zeric Tabekoueng , Jiang Donghua , Wu Jianhua , Awrejcewicz Jan 
Published: December 2023

Abstract
Jerk, as a mathematical concept, is used in mechanics to describe the rate of change of acceleration and plays a crucial role in the design of control systems for machines and vehicles. Therefore, it is important to master the various states and the energy released during the change of acceleration. This is why a new simple jerk function introduced afterward, energy released, is derived from a Hamilton function using the Helmholtz theorem. The condition of having a stable or unstable rate of change of acceleration is established using Hopf bifurcation theory. Some two-parameter stability charts are then computed for a suitable selection region of the study. Using some nonlinear analysis metrics, in the unstable region of the study, the occurrence of phenomena is found, such as reverse period doubling bifurcation, antimonotonicity, and hysteresis involving the coexistence of the states in the considered jerk system. An electronic circuit is built and used to implement the mathematical expression of the jerk equation and validate the result of the theoretical investigation.
Alleviating orbital angular momentum mode coupling between two ring-cores with different materials in a photonic crystal fiber for optical communication
Authors: Wang Xiaohui , Yu Yongze , Deng Dongdong , Mao Shuai , Wang Yang , Gu Haoyu , Song Yingxiong , Pang Fufei , Zhuang Liyun , Yang Song , He Xiaofeng , Wang Chao 
Published: December 2023

Abstract
A dual-ring photonic crystal fiber (PCF) is proposed, which not only supports the stable transmission of orbital angular momentum (OAM) modes but also deftly mitigates interference of mode coupling between the two rings. This fiber design possesses two concentric ring-cores and claddings, each constructed from distinct materials, effectively functioning as independent OAM channels. Importantly, the absence of significant mode coupling between the OAM modes of the two ring-cores guarantees unhindered transmission of the dual rings. Remarkably, the outer ring can accommodate 82 OAM modes of transmission and the inner ring can accommodate 34 OAM modes of transmission. High mode quality (>94.13%) is observed for all OAM modes in both inner and outer rings at wavelengths from 1.5 to 1.6 μm. This special design ensures that the modes in the outer ring have excellent performance and also maintains the modes in the inner ring as unaffected by the outer ring to the greatest extent.

Abstract
The elastic scattering angular distributions of

C at 340 MeV and

C at 294 MeV and 342 MeV on a

Pb target, which correspond to approximately five times the Coulomb barriers, were measured at the Radioactive Ion Beam Line in Lanzhou. The data were analyzed within the optical model and continuum-discretized coupled-channels (CDCC) framework, and the results of both calculations could effectively account for the experimental data. The differential cross sections of elastic scattering revealed no particular suppression at the Coulomb nuclear interference peak angles, suggesting that the breakup coupling effects on the elastic scattering angular distributions were negligibly small in this incident energy region. The contributions from the couplings with inelastic states to the elastic cross sections were of minor importance within the angular range covered by these experiments.
Active generation and control of radial electric field by local neutral beamlets injection in tokamaks

Published: December 2023

Abstract
The radial electric field plays an important role in plasma confinement in tokamaks and can be generated through neutral beam injection. In this study, we propose a model for calculating the radial electric field resulting from tangential local neutral beamlet injection, aiming to externally control and improve plasma confinement. The Neutral beamlet ion and Energetic particles Orbit mover and Electric field solver code has been developed to analyze this issue, and its simulation results have been validated against results from other codes as well as measurements from correlation reflectometers. The charge separation is primarily caused by the redistribution and loss of beam ions due to magnetic gradient and curvature drift as well as collision effects, and it is maintained through continuous beamlet injection. The electric field is calculated using Poisson’s equation, taking into account both classical and neoclassical polarization effects. The results demonstrate that despite the high losses and low heating efficiency associated with localized beamlets, they are capable of generating a significant radial electric field characterized by a steep gradient. This presents opportunities for external control of the electric field, potentially enhancing plasma confinement.
Fourier Transform from the Symmetric Square Representation of PGL2 and SL2
Authors: Laumon Gérard , Letellier Emmanuel 
Published: December 2023

Abstract
Let $G$ be a connected reductive group over $\overline{{\mathbb{F}}}_{q}$ and let $\rho ^{\vee }:G^{\vee }\rightarrow \mathrm{GL}_{n}$ be an algebraic representation of the dual group $G^{\vee }$. Assuming that $G$ and $\rho ^{\vee }$ are defined over ${\mathbb{F}}_{q}$, Braverman and Kazhdan defined an operator on the space ${{\mathcal{C}}}(G({\mathbb{F}}_{q}))$ of complex valued functions on $G({\mathbb{F}}_{q})$. In this paper we are interested in the case where $G$ is either $\mathrm{SL}_{2}$ or $\mathrm{PGL}_{2}$ and $\rho ^{\vee }$ is the symmetric square representation of $G^{\vee }$. We construct a natural $G\times G$-equivariant embedding $G\hookrightarrow{{\mathcal{G}}}={{\mathcal{G}}}_{\rho }$ and an involutive operator (Fourier transform) ${{\mathcal{F}}}^{{{\mathcal{G}}}}$ on the space of functions ${{\mathcal{C}}}({{\mathcal{G}}}({\mathbb{F}}_{q}))$ that extends Braverman-Kazhdan’s operator.
Defining Optimal Doses of Liposomal Amphotericin B Against Candida auris: Data From an In Vitro Pharmacokinetic/Pharmacodynamic Model
Authors: Beredaki Maria-Ioanna , Sanidopoulos Ioannis , Pournaras Spyros , Meletiadis Joseph 
Published: December 2023

Abstract

Background
Candida auris isolates exhibit elevated amphotericin B (AMB) minimum inhibitory concentrations (MICs). As liposomal AMB (L-AMB) can be safely administered at high doses, we explored L-AMB pharmacodynamics against C. auris isolates in an in vitro pharmacokinetic/pharmacodynamic (PK/PD) dilution model.

Methods
Four C. auris isolates with Clinical and Laboratory Standards Institute (CLSI) AMB MICs = 0.5–2 mg/L were tested in an in vitro PK/PD model simulating L-AMB pharmacokinetics. The in vitro model was validated using a Candida albicans isolate tested in animals. The peak concentration (Cmax)/MIC versus log10 colony-forming units (CFU)/mL reduction from the initial inoculum was analyzed with the sigmoidal model with variable slope (Emax model). Monte Carlo analysis was performed for the standard (3 mg/kg) and higher (5 mg/kg) L-AMB doses.

Results
The in vitro PK/PD relationship Cmax/MIC versus log10 CFU/mL reduction followed a sigmoidal pattern (R2 = 0.91 for C. albicans, R2 = 0.86 for C. auris). The Cmax/MIC associated with stasis was 2.1 for C. albicans and 9 for C. auris. The probability of target attainment was &gt;95% with 3 mg/kg for wild-type C. albicans isolates with MIC ≤2 mg/L and C. auris isolates with MIC ≤1 mg/L whereas 5 mg/kg L-AMB is needed for C. auris isolates with MIC 2 mg/L.

Conclusions
L-AMB was 4-fold less active against C. auris than C. albicans. Candida auris isolates with CLSI MIC 2 mg/L would require a higher L-AMB dose.

Authors: Shono Masato , Murakami Kosuke , Ohta Mamiko , Nakai Hidekatsu , Matsumura Noriomi 
Published: December 2023

Abstract
Drug-induced interstitial lung disease (DIILD) is one of the most common and important adverse drug reactions. Still, the details of the clinical presentation of DIILD caused by poly (adenosine diphosphate-ribose) polymerase (PARP) inhibitors are unknown.
A 73-year-old Japanese woman was started on niraparib maintenance therapy after radical surgery and adjuvant chemotherapy for high-grade serous carcinoma originating from the fallopian tube. Forty-seven days after starting niraparib, she presented to the hospital with dyspnea and was diagnosed with DIILD caused by niraparib. The drug was discontinued, and the patient was treated with steroid pulse therapy, and her condition improved.
In clinical trials of PARP inhibitors, DIILD was reported in 0.13% of patients with olaparib, but no DIILDs, including pneumonia or pneumonitis, were reported in any patient with niraparib. This is the first report of DIILD caused by niraparib worldwide. In the future, the frequency of DIILD caused by niraparib should be clarified in real-world data.
Co-option of an Astacin Metalloprotease Is Associated with an Evolutionarily Novel Feeding Morphology in a Predatory Nematode

Published: December 2023

Abstract
Animals consume a wide variety of food sources to adapt to different environments. However, the genetic mechanisms underlying the acquisition of evolutionarily novel feeding morphology remain largely unknown. While the nematode Caenorhabditis elegans feeds on bacteria, the satellite species Pristionchus pacificus exhibits predatory feeding behavior toward other nematodes, which is an evolutionarily novel feeding habit. Here, we found that the astacin metalloprotease Ppa-NAS-6 is required for the predatory killing by P. pacificus. Ppa-nas-6 mutants were defective in predation-associated characteristics, specifically the tooth morphogenesis and tooth movement during predation. Comparison of expression patterns and rescue experiments of nas-6 in P. pacificus and C. elegans suggested that alteration of the spatial expression patterns of NAS-6 may be vital for acquiring predation-related traits. Reporter analysis of the Ppa-nas-6 promoter in C. elegans revealed that the alteration in expression patterns was caused by evolutionary changes in cis- and trans-regulatory elements. This study suggests that the co-option of a metalloprotease is involved in an evolutionarily novel feeding morphology.
Language model-based B cell receptor sequence embeddings can effectively encode receptor specificity
Authors: Wang Meng , Patsenker Jonathan , Li Henry , Kluger Yuval , Kleinstein Steven H 
Published: December 2023

Abstract
High throughput sequencing of B cell receptors (BCRs) is increasingly applied to study the immense diversity of antibodies. Learning biologically meaningful embeddings of BCR sequences is beneficial for predictive modeling. Several embedding methods have been developed for BCRs, but no direct performance benchmarking exists. Moreover, the impact of the input sequence length and paired-chain information on the prediction remains to be explored. We evaluated the performance of multiple embedding models to predict BCR sequence properties and receptor specificity. Despite the differences in model architectures, most embeddings effectively capture BCR sequence properties and specificity. BCR-specific embeddings slightly outperform general protein language models in predicting specificity. In addition, incorporating full-length heavy chains and paired light chain sequences improves the prediction performance of all embeddings. This study provides insights into the properties of BCR embeddings to improve downstream prediction applications for antibody analysis and discovery.
Proportions of Pseudomonas aeruginosa and Antimicrobial-Resistant P aeruginosa Among Patients With Surgical Site Infections in China: A Systematic Review and Meta-analysis
Authors: Yang Yuhui , Zhang Li , Wang Jian , Chen Zongyue , Tong Liang , Wang Zhenkun , Li Gaoming , Luo Yu 
Published: December 2023

Abstract

Background
Pseudomonas aeruginosa is one of the most common pathogens in surgical site infections (SSIs). However, comprehensive epidemiological and antibiotic resistance details for P aeruginosa in Chinese SSIs are lacking. We evaluated the proportions and antimicrobial resistance of P aeruginosa among patients with SSIs in China.

Methods
Relevant papers from January 2010 to August 2022 were searched in databases including PubMed, Embase, Web of Science, China Biomedical Literature Database, China National Knowledge Infrastructure, Wanfang, and Weipu. A meta-analysis was performed to analyze the proportions and 95% confidence interval (CIs) of P aeruginosa among patients with SSIs. Meta-regression analysis was used to investigate the proportion difference among different subgroups and antimicrobial resistance.

Results
A total of 72 studies met inclusion criteria, involving 33 050 isolated strains. The overall proportion of P aeruginosa among patients with SSIs was 16.0% (95% CI, 13.9%–18.2%). Subgroup analysis showed higher proportions in orthopedic (18.3% [95% CI, 15.6%–21.0%]) and abdominal surgery (17.3% [95% CI, 9.9%–26.2%]). The proportion in the central region (18.6% [95% CI, 15.3%–22.1%]) was slightly higher than that in other regions. Antibiotic resistance rates significantly increased after 2015: cefoperazone (36.2%), ceftriaxone (38.9%), levofloxacin (20.5%), and aztreonam (24.0%). Notably, P aeruginosa resistance to ampicillin and cefazolin exceeded 90.0%.

Conclusions
The proportion of P aeruginosa infection among patients with SSIs was higher than the data reported by the Chinese Antimicrobial Resistance Surveillance System, indicating rising antimicrobial resistance. The existing antimicrobial drug management plan should be strengthened to prevent a hospital epidemic of drug-resistant P aeruginosa strains.
Keyboard Reductions and the Arrangement of Enlightenment Knowledge
Authors: Sheehan Desmond 
Published: December 2023

Abstract
What did it mean to “reduce” music in the eighteenth century? This chapter applies media-archeological methods to keyboard reductions in late eighteenth-century Germany and argues that the format of the Klavierauszug belonged to a larger proliferation of simplified instruction books and printed extracts (Auszüge), premised on a new logic of literary compression. It centers around two of Prussia’s most prolific music editors, Johann Adam Hiller in Leipzig and Johann Carl Friedrich Rellstab in Berlin. Their arrangements reveal several assumptions about techniques of knowledge reduction: how one turned complex sets of information into simpler, more legible forms. As Hiller and Rellstab conceived of it, the keyboard reduction was not a skeletal transcription harkening back to a more substantial original, but the distillation of musical knowledge that sought to capture the techno-affective core of a piece. Through this ethic of reduction, musical scores were invested with a new historical objectivity.
Baltic Calendrical Folklore
Authors: Seljamaa Elo-Hanna 
Published: December 2023

Abstract
This chapter uses the concept of “Baltic calendrical folklore” as a lens to examine how the region’s multi-tiered history is stratified into layers of ideas and customs pertaining to time and time reckoning. There exists in all three Baltic countries an established scholarly and popular notion of a distinctively ethnonational calendar with peasants’ annual holiday cycle at its core, and this chapter explores how and why this is the case. It gives an overview of the study of calendrical folklore in Estonia, Latvia, and Lithuania, starting from the Soviet era and moving back in time to nineteenth-century folklore-collecting campaigns, only to return to the present. The chapter also examines interactions between successive foreign rules and natives, describing intersections between regional and religious traditions as well as contestations surrounding calendrical customs originating in the Soviet era. Also discussed is the more recent impact of UNESCO’s concept of intangible cultural heritage.
Modern and Contemporary Muslim Feminist Literature
Authors: Cooke Miriam 
Published: December 2023

Abstract
This chapter reviews Arab, Iranian, and American novels, short stories, memoirs, and poems that engage with modern Muslim women’s concerns about the ways in which they have been held back from enjoying their rights as equal members of the Muslim communities in which they live. Although not without precedent, Muslim feminist literature is a modern phenomenon that was promoted in early twentieth-century Muslim women’s journals. The word “feminism” (nisā’iyya/nisāwiyya) took time to be accepted, especially against the backdrop of European colonial occupation of broad swathes of territory in Asia and Africa. In such areas, fear of association with the British colonizers, who pushed a self-serving colonial feminist policy in order to turn women against their men, made writers cautious about advocating an openly prowomen agenda. Nevertheless, a feminist consciousness did develop in the nineteenth century and gained momentum through the twentieth century, as manifested in a number of literary works penned by Muslim women authors. The works surveyed in this chapter document these women’s resistance and pushback against misogynist interpretations of specific Islamic texts and their attempts to promote instead gender egalitarian and women-friendly construals of the same.
Women’s Rights and Duties in Classical Legal Texts
Authors: DeLong-Bas Natana J. 
Published: December 2023

Abstract
This chapter provides a broad overview of the construction of the scholarly study of classical Islamic law pertaining to women and gender from the nineteenth century through the present. Such studies typically focus on the rediscovery and reinterpretation of the foundational texts of the Qur’ān and ḥadīth and on the distinction between Sharīʿa as universal values and objectives of the law versus fiqh as human-developed jurisprudence particular to a given context. Deconstruction of categories of women, rights and duties, and classical legal literature are engaged with attention to marriage, divorce, motherhood, and children.
