Authors: Amalraj Jansi Rani , Lourdusamy Robert 
Published: February 2022

Abstract
Securing medical records is a significant task in Healthcare communication. The major setback during the transfer of medical data in the electronic medium is the inherent difficulty in preserving data confidentiality and patients’ privacy. The innovation in technology and improvisation in the medical field has given numerous advancements in transferring the medical data with foolproof security. In today’s healthcare industry, federated network operation is gaining significance to deal with distributed network resources due to the efficient handling of privacy issues. The design of a federated security system for healthcare services is one of the intense research topics. This article highlights the importance of federated learning in healthcare. Also, the article discusses the privacy and security issues in communicating the e-health data.
K-stability of cubic fourfolds
Authors: Liu Yuchen 
Published: February 2022

Abstract
We prove that the K-moduli space of cubic fourfolds is identical to their GIT moduli space.
More precisely, the K-(semi/poly)stability of cubic fourfolds coincide to the corresponding GIT stabilities, which was studied in detail by Laza. In particular, this implies that all smooth cubic fourfolds admit Kähler–Einstein metrics. Key ingredients are local volume estimates in dimension three due to Liu and Xu, and Ambro–Kawamata’s non-vanishing theorem for Fano fourfolds.
A description of monodromic mixed Hodge modules
Authors: Saito Takahiro 
Published: February 2022

Abstract
For a smooth algebraic variety X, a monodromic D-module on

X
×
ℂ

{X\times\mathbb{C}}

is decomposed into a direct sum of some D-modules on X.
We show that the Hodge filtration of a mixed Hodge module on

X
×
ℂ

{X\times\mathbb{C}}

whose underlying D-module is monodromic is also decomposed.
Moreover, we show that there is an equivalence of categories between the category of monodromic mixed Hodge modules on

X
×
ℂ

{X\times\mathbb{C}}

and the category of “gluing data”.
As an application, we endow the Fourier–Laplace transformation of the underlying D-module of a monodromic mixed Hodge module with a mixed Hodge module structure.
The Potentials and Occlusions of Zhonghua Minguo/Taiwan: In Search of a Left Nationalism in the Tsai Ing-wen Era
Authors: McConaghy Mark 
Published: February 2022

Abstract
Tsai Ing-wen has consistently referred to the nation that she governs as 中華民國台灣 (The Republic of China Taiwan), the term representing a major rhetorical feature of her administration. Breaking from the exclusively Taiwan-centered discourse which traditionally defined DPP politics, Tsai has seemingly created an entirely new name for the state she governs. This article examines both the discursive potentials, but also the occlusions, of this newly coined neologism. It argues that the term is defined by a lack of materialist critique, in which essential questions regarding labor exploitation and private property regimes remain unaddressed. While Tsai has successfully combined the ROC’s old Cold War raison d'etre (Chinese humanism as anti-Communism) with the Taiwanese independence movement’s desire for global recognition through the nation-state form, what has been lost is any real commitment to a politics of working-class empowerment, which is reflected in the Tsai administration’s abandonment of progressive labor law reform in 2018, as well as increasing trade liberalization policies with the US introduced in 2020. Returning to the roots of Taiwanese socialist discourse, this article will examine the possibility that “ROC-Taiwan” as a political project could still have a socialist future, despite its markedly capitalist past and present.

Abstract

Objectives
Cytochrome P450 (CYP450) is a major enzyme system involved in drug metabolism as well as regulation of brain function. Although individual variability in CYP enzymes have been studied in terms of personality traits and treatment effects, no study up to now evaluated CYP polymorphisms in children with attention deficit/hyperactivity disorder (ADHD). We aimed to define the genetic profiles of CYP2D6 and CYP2C19 relevant alleles in children with ADHD according to treatment status and compare the frequencies according to past results.

Methods
Three hundred and seventeen patients with ADHD-Combined Presentation were enrolled; symptom severity was evaluated by parents and clinicians while adverse effects of previous treatments were evaluated with parent and child reports. Reverse blotting on strip assays was used for genotyping and descriptive and bivariate analyses were conducted. A p-value was set at 0.05 (two-tailed).

Results
Children were divided into treatment-naïve (n=194, 61.2%) and treatment-resistant (n=123, 38.8%) groups. Within the whole sample PM, EM and UM status according to 2D6 were 3.8% (n=12), 94.3% (n=299) and 21.9% (n=6); respectively. PM, IM, EM and UM status according to 2C19 were 2.5% (n=8), 19.8% (n=63), 48.6% (n=154) and 29.0% (n=92), respectively. No relationship with treatment resistance, comorbidity or gender could be found. Importantly, CYP2C19 UMs were significantly more frequent in ADHD patients compared to previous studies in the general population.

Conclusions
CYPs may be a rewarding avenue of research to elucidate the etiology and treatment of patients with ADHD.
Factors influencing methotrexate and methotrexate polyglutamate in patients with rheumatoid arthritis: a systematic review of population pharmacokinetics
Authors: Methaneethorn Janthima , AlEjielat Rowan , Leelakanok Nattawut 
Published: February 2022

Abstract
Low dose methotrexate (MTX) is commonly used in the treatment of rheumatoid arthritis. The clinical effect is mediated by its metabolite, methotrexate polyglutamate (MTX-PGn). The drug exhibits high interindividual pharmacokinetic variability and the optimal MTX dose is different among individuals. Thus, several MTX population pharmacokinetic (PopPK) models were developed to characterize factors affecting MTX pharmacokinetic variability. This review summarizes significant predictors for MTX pharmacokinetics and identifies knowledge gaps to be further examined. A total of 359 articles were identified from a systematic search of four databases: PubMed, Science Direct, and CINAHL Complete. Of these eight studies were included. Most studies investigated influential factors on MTX pharmacokinetics, but information on MTX-PGn is limited, with only one study performing a parent-metabolite (MTX-PG3) model. MTX pharmacokinetics was described using a two-compartment model with first-order elimination in most studies, with the MTX clearance ranging from 6.94 to 12.39 L/h. Significant predictors influencing MTX clearance included weight, creatinine clearance, sex, OATP1B3 polymorphism, and MTX multiple dosing. While body mass index and red blood cell counts were significant predictors for MTX-PG3 clearance. Providing that MTX-PGn plays a crucial role in clinical effect, further studies should determine other factors affecting MTX-PGn as well as its relationship with clinical response.
Do we need critical educational linguistics?
Authors: Spolsky Bernard 
Published: February 2022

AbstractOver the past 30 years, the term “criticality” has become increasingly common in studies of educational and applied linguistics. Derived originally from the work of the Frankfurt School and widened by the linguistic turn in the writing of Habermas, the first linguistic sub-field was Critical Discourse Analysis, proposed by British scholars. In 1990, Alastair Pennycook called for critical applied linguistics, and in 2021 traced its expansion over thirty years. Given the steady deterioration of the modern world and its effects on language teaching and use, there is good reason to encourage critical approaches to educational linguistics and to seek solutions to the current crises. But continued critique without solutions in praxis is not desirable.
Quantitative analysis of DC–DC converter models: a statistical perspective based on solar photovoltaic power storage
Authors: Hole Shreyas Rajendra , Goswami Agam Das 
Published: February 2022

Abstract
Photovoltaic (PV) systems have paved their way into general households due to their high efficiency, low deployment cost and huge power savings. These advantages combined with Government incentives further assist in wide-scale adoptability of the solar powered systems. PV systems generate direct current (DC) outputs, which needs to be converted into alternating current (AC) via inverters. The efficiency of inverter design decides the overall efficiency of the PV system, which allows effective utilization of the solar power for feeding to grid or for local usage. In order to design effective inverter models, a large number of electrical configurations are designed by researchers over the years. These include, stand-alone inverters, grid-tie inverters, battery backup inverters and hybrid inverters, each of which are further divided into multiple sub-categories. Each of these sub-categories have a different application, for instance, string-converters are used for moderate power applications up-to 150k W, while central converters are used for high power applications above 80k W, etc. Apart from power capabilities, these designs vary in terms of efficiency of conversion, usability, cost, etc. Due to so many parametric variations, effective selection of these converters for a given PV application becomes ambiguous. In order to reduce this ambiguity, the underlying text statistically evaluates performance of some of the most efficient PV converter models, and compares them on the basis of power capabilities, accuracy of conversion, converter used, control model used, etc. This review will assist researchers and system designers to select the best suited models for their given applications, and thus reduce the time needed for efficient PV inverter system design. This text also recommends future research which can be adopted for improving efficiency of these systems.
Numerical modelling of coronavirus pandemic in Peru
Authors: Jiménez César , Merma Marco 
Published: February 2022

Abstract

Objectives
The main objective of this research is to demonstrate the effectiveness of non-pharmaceutical interventions (social isolation and quarantine) and of vaccination.

Methods
The SIR epidemiological numerical model has been revised to obtain a new model (SAIRDQ), which involves additional variables: the population that died due to the disease (D), the isolated (A), quarantined population (Q) and the effect of vaccination. We have obtained the epidemiological parameters from the data, which are not constant during the evolution of the pandemic, using an iterative approximation method.

Results
Analysis of the data of infected and deceased suggest that the evolution of the coronavirus epidemic in Peru has arrived at the end of the second wave (around October 2021). We have simulated the effect of quarantine and vaccination, which are effective measures to reduce the impact of the pandemic. For a variable infection and isolation rate, due to the end of the quarantine, the death toll would be around 200 thousand; if the isolation and quarantine were relaxed since March 01, 2021, there could be more than 280 thousand deaths.

Conclusions
Without non-pharmaceutical interventions and vaccination, the number of deaths would be much higher than 280 thousand.
A lightweight polyurethane-carbon microsphere composite foam for electromagnetic shielding
Authors: Liang Shaofeng , Qin Yuxuan , Gao Wei , Wang Muqun 
Published: February 2022

Abstract
In this study, we have produced a lightweight foam composite material by a simple freeze-drying method, which is composed of carboxylated multi-walled carbon nanotubes (MWCNTs), mesoporous carbon hollow microspheres (MCHMs), water-based polyurethane (WPU), and polyvinyl alcohol (PVA). MCHMs were prepared by a novel and facile method. We found that the electromagnetic shielding performance of foam composites can be adjusted by adjusting the density of foam composites, and the electromagnetic shielding performance of composites can be enhanced through the synergistic effect of hollow mesoporous carbon and MWCNTs. The composite material with a density of 232.8042 mg·cm−3 and 40 wt% MWCNT has a δ of 30.2 S·m−1 and SE of 23 dB. After adding 10 wt% MCHMs to the composite material, δ reaches 33.2 S·m−1, and SE reaches 28 dB. Both absorption losses accounted for 70%. The increase in the content of MWCNT, the increase in density, and the introduction of MCHMs all have a positive effect on the δ and SE of the composite material.
Effects of chitosan and Tween 80 addition on the properties of nanofiber mat through the electrospinning
Authors: Boonpratum Chalongwut , Naemchanthara Patcharin , Limsuwan Pichet , Naemchanthara Kittisakchai 
Published: February 2022

Abstract
Chitosan (CS) with excellent biomedical properties was mixed with polyvinyl alcohol (PVA) to be used as the spinning solution. The spinning solutions with various concentrations of CS:PVA from 10:90% to 50:50% (v/v) were investigated. Tween 80 (T80) was added in the spinning solutions of CS and PVA. The nanofiber mats with and without T80 addition obtained from the spinning solutions by electrospinning technique were investigated and addressed. The results showed that the viscosity of the CS and PVA spinning solutions increased with increasing the CS concentration, whereas the viscosity decreased after T80 addition. The nanofiber mats with 10–30% CS concentrations were prepared successfully as a smooth surface and high dense nanofiber mat. The average diameter of the nanofiber decreased with increasing the CS concentration. The increase in the CS concentration of the nanofiber mat can increase the mechanical and antibacterial properties, whereas the wettability and drug release property were decreased. Moreover, the nanofiber mats with T80 addition had higher mechanical property and wettability than the nanofiber mats without T80 addition. Finally, the T80 addition can enhance hydrophilicity and promote the drug release property of the nanofiber mat.
Professional intercultural communicative competence and labour market integration among highly-educated refugees in the Netherlands
Authors: Schukking Anna Fardau , Kircher Ruth 
Published: February 2022

Abstract
In the last decade, thousands of forcibly-displaced people have sought refuge in the Netherlands. Many of them are highly educated, and their integration into the host society’s labour market could improve their own quality of life as well as making a significant contribution to the country’s economy. However, refugees face many challenges in their search for employment. This is the first exploratory study of the role that professional intercultural communicative competence (PICC) plays in highly-educated refugees’ integration in the Dutch labour market. Interviews and focus groups were used to collect data from refugees who had already successfully integrated into the Dutch workforce as well as from newcomers who were still in the process of achieving this. Content analysis was performed on the data, using rounds of deductive and inductive coding and analysis. The findings indicate that the development of PICC (including resilience) plays an important role in helping refugees overcome the challenges they face. The article discusses the implications of the findings – should they generalise – in terms of PICC training offered to refugees themselves (as part of their language courses) and to professionals who work with them, with the aim of facilitating and promoting the refugees’ labour market integration.
A mathematical conjecture associates Martian TARs with sand ripples
Authors: Zhang Jinghong , Zheng Xiaojing , Zhu Wei 
Published: February 2022

Abstract
Considering that aeolian sand ripples are formed primarily by creeping particles caused by wind-driven saltation sand particles, we obtain a formulation for determining the height of saturated aeolian sand ripples by incorporating the reptation fluxes with previous experimental results on migration velocities of sand ripples. Based on existing observational results of terrestrial sand ripples on Earth's surface, it estimates that the wavelength of aeolian sand ripples on Mars is generally up to several meters. This implies a possibility that there is another sand ripple on Mars similar in scale to Transverse Aeolian Ridges (TARs) at some time when surface saltation was prevalent. Moreover, perhaps part of the widely observed TARs is the degradation of saltation sand ripples, whose formation is intimately related to saltation and reptation of sand particles. While the other two types of ripple-like morphologies (plain ripples and crater ripples) found by Opportunity Rover are essentially not. Further, we propose that the main factor controlling the scale feature of Martian sand ripples is the intense particle-bed collision process.
Research on comprehensive benefits and reasonable selection of marine resources development types
Authors: Sun Huihui , Gao Sheng , Liu Jinfu , Liu Wei 
Published: February 2022

AbstractThe comprehensive benefit evaluation of marine resources developmental model is of great significance to choose the appropriate types of marine resources development and promote the intensive utilization and sustainable development of marine resources. This article examined five types of marine resources development, such as marine protected areas, mariculture, offshore wind power, sewage dumping, and land reclamation, and constructed a three-level evaluation index system for the comprehensive benefits of marine resources development. The projection pursuit clustering model was used to evaluate and analyze the comprehensive benefits and main influencing factors of 15 marine resources development projects in Jiangsu Province, China. It was found that the comprehensive benefit projection values of marine protected areas and offshore wind power are higher. The projection value of comprehensive benefit of land reclamation is the lowest. The main influencing factors include but not limited to the change rate of total output of aquatic products, contradiction between management and marine use, negative impact on residents’ lives, etc. The research results have important guiding significance for promoting the rational development and utilization of marine resources and the high-quality development of the oceans.
Activation of Ad Damm shear zone, western Saudi Arabian margin, and its relation to the Red Sea rift system
Authors: Samkari Abdulaziz , Farris David W. , Baggazi Haitham M. 
Published: February 2022

Abstract
The Ad Damm shear zone (ADSZ) is a major mylonitic right-lateral structure that bounds the Jeddah terrane to the north from the Asir terrane to the south. High-resolution field mapping coupled with petrological and geochemical analyses indicate that Jeddah terrane is characterized by heterogeneous magmatism with extensive meta-basalt intruded by silicic plutons of varying size. South of the ADSZ, Asir terrane is characterized by larger scale granitic batholiths. A younger generation of Eocene–Miocene basaltic dikes cut the mylonitic shear zone at a high angle. Petrographic analyses of the ADSZ mylonitic rocks indicate dynamic recrystallization and grain-size reduction, suggesting high-temperature recrystallization. Field observations also found a lack of low-temperature fault zone rocks (e.g. gouge) except for isolated brittle slickensides. Spider diagrams of Jeddah, Asir terranes, and ADSZ rocks are characterized by an arc-related signature, which related to the amalgamation of Jeddah and Asir terranes and defined ADSZ as Neoproterozoic structure. In contrast, Eocene–Miocene basaltic dikes and southern basaltic flow are represented by a rift-related signature, which associated with the development of the Red Sea rift system. Offshore, south of the ADSZ, the Red Sea rift exhibits well-developed linear magnetic anomalies and large topographic escarpment perpendicular to the rift margin, but they are not present north of it. In addition, recent seismicity recorded along the ADSZ and differences in the crustal thickness and characteristics of Asir and Jeddah terranes, collectively, make ADSZ acted as an active crustal boundary and still influence the ongoing tectonic evolution of the Red Sea rift.
Chemical characteristics of heterogeneous lignocellulosic microfines prepared using the glycol ether-organosolv process: dissolution properties in an NaOH–urea aqueous solution
Authors: Kim Kang-Jae , Ryu Ji-Ae , Eom Tae-Jin 
Published: February 2022

Abstract
In this study, heterogeneous lignocellulosic microfines (LCMFs) with different physicochemical properties were prepared from softwood by adjusting the reaction conditions of a glycol ether-organosolv process. The dissolution properties of heterogeneous LCMFs in an NaOH–urea aqueous solution were evaluated. As the reaction time increased, the yield and residual lignin content decreased. As the amount of chemical solution used to prepare LCMFs increased, more lignin than carbohydrates were removed, but the degree of polymerization (DP) was maintained. Finally, LCMFs with different residual lignin content, DP, and crystallinity were prepared via the glycol ether-organosolv process under various conditions. It was observed that lower the lignin content of heterogeneous LCMFs, higher were their solubilities in the NaOH–urea solution. The effect of DP on solubility was not significant; however, the hemicellulose content of LCMFs had a greater effect on their solubilities in the NaOH–urea aqueous solution than the sugar composition of hemicellulose. The chemical properties of lignin present in LCMFs had no significant effect on their solubilities in the NaOH–urea aqueous solution.

Published: February 2022

Abstract
The low density and light color of faber fir [Abies. fabri (Mast.) Craib] wood have limited its applications in interior decoration and wall panels. In order to increase the density of faber fir and thus expand its scope of application, this study chemically pretreated the wood firstly, and then pressed it at high temperatures to make densified wood. The microscopic morphology and mechanical property tests showed that the performances of densified wood were greatly enhanced compared with the natural wood. When the pretreatment time was 10 h, the cell lumen size of densified wood became extremely small, resulting in a density of 1160 kg m−3 and a relative crystallinity of 76.9%. Moreover, the mean flexural strength and elastic modulus of the densified wood with a pretreatment process of 10 h were 191 MPa and 23.4 GPa, which were 170% and 230% higher than the natural wood. In addition, the obtained high-strength wood was infused with paraffin to improve dimensional stability without compromising the high strength of the densified wood. The performance test showed that the thickness swelling of the treated densified wood was only 0.6% (after 72 h water absorption), showing excellent dimensional stability.
