A newly developed screening current simulation method for REBCO pancake coils based on extension of PEEC model
Authors: Noguchi So , Hahn Seungyong 
Published: February 2022

Abstract
Since the screening current (SC) in rare earth-barium-copper-oxide (REBCO) coated conductor (CC) generates an undesired magnetic field, it must be accurately estimated, especially for magnetic resonance imaging (MRI) and nuclear magnetic resonance (NMR). Moreover, in recent years, it was pointed out that the screening current enhanced the stress/strain in REBCO CC, when an REBCO magnet was operated as an insert under an ultrahigh magnetic field. The previously reported SC simulation methods may be roughly categorized into finite element method (FEM) and equivalent circuit method. The FEM-based method often adopted an axisymmetric model or a thin film approximation model, while the circuit-based are the simple equivalent circuit model and the network equivalent circuit model, so-called the partial element equivalent circuit (PEEC) model. The latter is newly developed in this paper. Features of those SC simulation models are briefly compared to each other in this paper. Each SC simulation models have pros & cons. We have to adequately chose an SC simulation model depending on a purpose. We extended the original PEEC model to simulate SC. The extended model is named the advanced partial element equivalent circuit (A-PEEC) model. It is also extendable to an SC simulation of no-insulation REBCO pancake coils. To simulate the SC of a simple coil model and the LBC3 magnet, we investigated the screening current distribution maps, and the simulated screening current-induced fields were compared with the measurements. We have confirmed the validity of the newly developed A-PEEC model.

Published: February 2022

Abstract
In this paper, the separation of variables method is applied to investigate the effects of solution pH, background salt concentration and AC electric field frequency on time periodic electroosmotic flow in a pH-regulated parallel-plate nanochannel. The surface charge is generated by the protonation and deprotonation of the functional group SiOH. The background salt is KCl. The pH value of the solution is adjusted by HCl and KOH. Analytical and semi-analytical solutions for electric potential and velocity distributions are obtained. The results show that the electric potential caused by the electric double layer depends greatly on the solution pH and background salt concentration. The amplitudes of the velocity and flow rate of the time periodic electroosmotic flow decrease with the background salt concentration and increase with the deviation of the solution pH from the isoelectric point. In a nanochannel having a height less than 100 nm, the electroosmotic velocity amplitude is not affected by the AC electric field frequency because the oscillating Reynolds number is much less than unity.

Abstract
Industrial growth in Indonesia is increasing along with the development of science and technology, for example is the textile industry. Generally the wasted produced by the textile industry is in the form of colored liquid waste which contains various textile coloring agents. One of the substances that lead to pollution in wastewater is the congo red content in it. A method that can be used to treat textile wastewater is AOPS (Advanced Oxidation Processes) using Fenton reagent which are a mixture of hydrogen peroxide and ferro ions based on the formation of hydroxyl radicals (•OH). The hydroxyl radical can be maximized by adding UV light to the H2O2/Fe2+ system and adding TiO2 photocatalysts. The results showed that TiO2 in the Fenton/UV system could increase the decrease in concentration of congo red. The decrease in concentration of congo red with the fenton/TiO2 system was 97,32% with the contribution of 100 ppm H2O2, FeSO4.7H2O 20 mg, and TiO2 0.2 gram.

Abstract
Endophytic fungi are friendly microbes colonizing in plants and play an effective role in plant-environment interactions. They produce valuable secondary metabolites that both plants and human beings can benefit from such products. In this study, an antioxidant-producing endophytic fungi were screened and identified from the leaves of Hippobroma longiflora (L.) G. Don which is one of the traditional medicinal plants. The objective of this study to evaluate the antioxidant activity of ethyl acetate extracts of 6 endophytic fungi isolated from Hippobroma longiflora (L.) G. Don. The qualitative and quantitative antioxidant activity was screened by scavenging 2,2-diphenyl-l-picrylhydrazyl (DPPH). Qualitatively 6 extracts from the endophytic fungi isolates (AOL1, AOL2, AOL3, AOL4, AOL5, and AOL6) from Hippobroma longiflora (L.) G. Don showed antioxidant activity, but quantitatively the extracts that showed very strong activity was extracts from AOL1 isolate with IC50 values of 28.50 μg/mL. Based on phenotypic and molecular identification AOL1 isolate identified as Phyllosticta sp and produce alkaloid, flavonoid, and terpenoid.

Abstract
The palm plant group exists widespread in the world, including in Indonesia. The palm population occupies limited and specific scope areas. Palm diversity on Mt Slamet of Central Java, Indonesia, has not been reported. This study aimed to reveal the existence of palm diversity that occupies different sides of Mt. Slamet, i.e., the southern, the eastern, the western, and the northern slopes. The method used purposive sampling consisting of 236 10×10-m-plots on the palm population found along the climbing path of the four sides. The results showed that the diversity of the palm within each slope was significantly different. The palm diversity on the southern slope reveals the highest species richness and abundance with Pinanga javana. However, there is no single palm population existing on the eastern slope. The palm population on the western and northern slopes was not significantly different because of the similar number of species found. The southern slope has more stable microclimate factors, such as rainfall and temperature, that support the conclusion that the habitat on the area is in the most stable condition for the palm population.

Abstract
Gemor (Nothaphoebe coriacea) is a plant that grows in wetland forests. Many studies have revealed the potential of this plant for health and medicine, among others as an antioxidant, anti-inflammatory, antidiabetic, and others. However, the mechanism is unknown or not yet discovered. Previous studies have shown that gemor bark contains active compounds. One of them is 4-ethyl-2-metoxyphenol (PubChem ID 62465) and 1,3-cyclo pentanedione (PubChem CID 77466) compounds. This research will prove that 2 compounds act as antidiabetic by influencing Glucagon like-Peptide-1 (GLP-1) Receptor. Molecular docking was carried out on 2 these compounds. The protein is taken from RCSB PDB (4ZGM). Ligand and protein preparation, analyzed and visualized docking results were carried out with the Chimera 1.14. Molecular docking using SWISSDOCK. The results show that the 4-ethyl-2-methoxyphenol compound can be bound by 6 residues (SER 84, CYS 85, TRP 87, ALA 92, VAL 95, and Pro 96); 1,3-cyclopentanedione bind by 7 residues (GLY 45, CYS 46, TYR 42, SER 49, CYS 71, VAL 83 and PRO 73). Gibbs energy for 4-Ethyl-2-methoxyphenol and 1,3-Cyclopentanedione, against GLP-1 Receptor each -6.10 kcal/mol and -5.37 kcal/mol. The conclusion is that 4-Ethyl-2-methoxyphenol and 1,3-Cyclopentanedione compound has the potential as an antidiabetic by binding mechanism with residues of GLP-1 receptor.

Published: February 2022

Abstract
Lonely people tend to evaluate social exchanges negatively and to display difficulties in interactions. Interpersonal synchronization is crucial for achieving positive interactions, promoting affinity, closeness, and satisfaction. However, little is known about lonely individuals’ ability to synchronize and about their brain activity while synchronizing. Following the screening of 303 participants, we recruited 32 low and 32 high loneliness participants. They were scanned while engaged in movement synchronization, using a novel dyadic interaction paradigm. Results showed that high loneliness individuals exhibited a reduced ability to adapt their movement to their partner’s movement. Intriguingly, during movement adaptation periods, high loneliness individuals showed increased activation in the action observation (AO) system, specifically in the inferior frontal gyrus and the inferior parietal lobule. They did not show increased activation in the dorsomedial prefrontal cortex, which in the context of synchronization was suggested to be related to gap-monitoring. Based on these findings, we propose a model according to which lonely people may require stronger activation of their AO system for alignment, to compensate for some deficiency in their synchronization ability. Despite this hyperactivation, they still suffer from reduced synchronization capacity. Consequently, synchronization may be a relevant intervention area for the amelioration of loneliness.
Transient compartmentalization and accelerated volume growth coincide with the expected development of cortical afferents in the human neostriatum

Abstract
The neostriatum plays a central role in cortico-subcortical circuitry underlying goal-directed behavior. The adult mammalian neostriatum shows chemical and cytoarchitectonic compartmentalization in line with the connectivity. However, it is poorly understood how and when fetal compartmentalization (AChE-rich islands, nonreactive matrix) switches to adult (AChE-poor striosomes, reactive matrix) and how this relates to the ingrowth of corticostriatal afferents. Here, we analyze neostriatal compartments on postmortem human brains from 9 postconceptional week (PCW) to 18 postnatal months (PM), using Nissl staining, histochemical techniques (AChE, PAS-Alcian), immunohistochemistry, stereology, and comparing data with volume-growth of in vivo and in vitro MRI. We find that compartmentalization (C) follows a two-compartment (2-C) pattern around 10PCW and is transformed into a midgestational labyrinth-like 3-C pattern (patches, AChE-nonreactive perimeters, matrix), peaking between 22 and 28PCW during accelerated volume-growth. Finally, compartmentalization resolves perinatally, by the decrease in transient “AChE-clumping,” disappearance of AChE-nonreactive, ECM-rich perimeters, and an increase in matrix reactivity. The initial “mature” pattern appears around 9 PM. Therefore, transient, a 3-C pattern and accelerated neostriatal growth coincide with the expected timing of the nonhomogeneous distribution of corticostriatal afferents. The decrease in growth-related AChE activity and transfiguration of corticostriatal terminals are putative mechanisms underlying fetal compartments reorganization. Our findings serve as normative for studying neurodevelopmental disorders.

Abstract
The spatiotemporal dynamics of interaction between slow (delta or infraslow) waves and fast (gamma) activities during wakefulness and sleep are yet to be elucidated in human electrocorticography (ECoG). We evaluated phase-amplitude coupling (PAC), which reflects neuronal coding in information processing, using ECoG in 11 patients with intractable focal epilepsy. PAC was observed between slow waves of 0.5–0.6 Hz and gamma activities, not only during light sleep and slow-wave sleep (SWS) but even during wakefulness and rapid eye movement (REM) sleep. While PAC was high over a large region during SWS, it was stronger in the posterior cortical region around the temporoparietal junction than in the frontal cortical region during REM sleep. PAC tended to be higher in the posterior cortical region than in the frontal cortical region even during wakefulness. Our findings suggest that the posterior cortical region has a functional role in REM sleep and may contribute to the maintenance of the dreaming experience.
Hong Kong’s National Security Law: A Socialist Legal Transplant?
Authors: Pascoe Daniel 
Published: February 2022

Abstract
The recently enacted Law of the People’s Republic of China on Safeguarding National Security in the Hong Kong Special Administrative Region (NSL) is unique in global perspective: it was both drafted by and adopted from a jurisdiction espousing an entirely different type of legal system. In this article, I consider the NSL as a potential socialist legal transplant from the People’s Republic of China to its Special Administrative Region of Hong Kong upon its promulgation in June 2020. I consider why, in the criminal law context, the NSL bears certain socialist characteristics and may even be classified as a socialist law. I also consider whether the NSL might be the world’s first ever socialist criminal law transplant into a common law jurisdiction, and discuss what this might mean for legal interpretation and comparative law scholarship more generally. While existing comparative law scholarship on legal transplants has focused, where relevant, on transplants into States espousing socialist legal systems or between such systems, rarely have scholars encountered and analysed laws making their way across legal boundaries in the other direction. This article uses the example of the NSL, enacted by the Standing Committee of the National People’s Congress in Beijing and applied to Hong Kong’s common law legal system, to begin to fill the gap.
Immigrant Youth Program: A Model for Educational and Personal Success

Published: February 2022

Abstract
Central American youth constitute one of the largest groups of newcomers in U.S. public schools, particularly in urban areas. Many have experienced traumatic events and interrupted or limited formal education. These factors, coupled with cultural and language differences, may lead these youth to struggle in public schools, unless specifically tailored programming is provided. The loss of family, and what is familiar to them, may lead them to feel alone. This article presents a model that meets the unique academic and mental health needs of Central American immigrant youth by harnessing the power of community in a school setting. The study findings indicate that a model premised on relational safety, cultural acceptance, and educational support enhances students’ motivation and commitment to their academic and professional goals. Further, creating an environment that prioritizes a sense of belonging can foster a sense of well-being. School social workers are critical to the implementation of such a model, which requires a nuanced understanding of cultural context, sociopolitical factors that surround public policy, lived experience, impact of trauma, and the recognition of the innate strength of these youth. The article presents a way for navigating the challenges, while maximizing the power of community and belonging in these children’s lives.
The effects of prey lipid on female mating and reproduction of a wolf spider

Published: February 2022

Abstract
As predators, the macronutrients spiders extract from their prey play important roles in their mating and reproduction. Previous studies of macronutrients on spider mating and reproduction focus on protein, the potential impact of prey lipid content on spider mating and reproduction remains largely unexplored. Here, we tested the influence of prey varying in lipid content on female mating, sexual cannibalism, reproduction, and offspring fitness in the wolf spider Pardosa pseudoannulata. We acquired 2 groups of fruit fly Drosophila melanogaster that differed significantly in lipid but not protein content by supplementing cultural media with a high or low dose of sucrose on which the fruit flies were reared (HL: high lipid and LL: low lipid). Subadult (i.e., 1 molt before adult) female spiders that fed HL flies matured with significantly higher lipid content than those fed LL flies. We found that the mated females fed with HL flies significantly shortened pre-oviposition time and resulted in a significantly higher fecundity. However, there was no significant difference in female spiders varying in lipid content on other behaviors and traits, including the latency to courtship, courtship duration, mating, copulation duration, sexual cannibalism, offspring body size, and survival. Hence, our results suggest that the lipid content of prey may be a limiting factor for female reproduction, but not for other behavioral traits in the wolf spiders P. pseudoannulata.
