Load security region determination with second order cone programming relaxation
Authors:   , Sukheeboon Pongsakorn 
Published: April 2023

Thailand’s electricity peak demand is increasing continuously. When load demand increases, power generation will increase to respond to the load. However, load demand cannot increase beyond power system constraints which include voltage magnitude limit, generation limit, and transmission line limit. This work determines the load security region which is the feasible region of the power system. The load security region is a set of power system solution which does not violate the power system constraints. The load security region is considered by using a tracing algorithm. This method consists of predictor process and corrector process. The corrector process is an optimization-based method that is used to find the shortest path between the prediction point and the boundary point. Moreover, this work formulates optimization-based method which is nonlinear and nonconvex to be convex by using second order cone programming (SOCP) relaxation. The results show that the load security region of the power system test case. The load security region is represented in the P-Q plane. In addition, the load security region can be used to plan the power system operation, such as load shedding, and photovoltaic (PV) installation. The load security region can be increased or moved due to the system parameter from these operations. Thereby, these operations can change the load security region shape.

Published: April 2023

A escolarização da população com deficiência múltipla ainda enfrenta inúmeros desafios no contexto brasileiro. Nesse sentido, este artigo analisa os indicadores de matrículas de alunos com deficiência múltipla entre 1974 e 2021 e as orientações políticas para a educação dessa parcela da população. Em termos metodológicos, foram analisados documentos normativos e orientadores sobre o público da Educação Especial e levantamentos estatísticos do Instituto Nacional de Estudos e Pesquisas Educacionais Anísio Teixeira (Inep). As análises mostraram, entre outros aspectos, aumento das matrículas de pessoas com deficiência múltipla em escolas comuns de ensino, falta de consenso sobre quem e quantos seriam esses alunos nos documentos oficiais, fragilidades nas diretrizes políticas sobre ações intersetoriais e estratégias educativas, sobretudo daqueles que demandam intervenções pedagógicas mais específicas, como o uso da comunicação alternativa, por exemplo, o caso das crianças acometidas pela Síndrome Congênita do Zika Vírus.
MOBILE TECHNOLOGY FOR ENGLISH LANGUAGE CLASSROOMS: STUDENTS’ AND TRAINEE TEACHERS’ REFLECTIVE VIEWS OF CELL PHONES FOR ENGLISH LANGUAGE LEARNING AND TEACHING
Authors: Tesfaye Habtemariam  
Published: April 2023

Even if scholars realize the emergence of cell phones opening up a range of opportunities for ‘learning on the move’, there are not many studies on how they can be used and how students and trainee teachers view them as tools for English Language Teaching and Learning in EFL context. This case study, therefore, aims to explore students’ post-intervention views to mobile assisted lessons, examine trainee teachers’ reaction to the experience of teaching with cell phones and identify issues with learning and teaching reading and listening with Cell phones. To achieve these objectives, twelve trainee teachers’ short-time attachment reports to five secondary schools, one teacher training college and one university on applying cell phones for teaching listening and reading skills as part of the tasks for their Computer Assisted Language Learning (CALL) course during 2015 to 2017 academic years were analyzed. The reports indicated that students viewed cell phones as useful tools for learning reading and listening, but it was also reported that they were concerned with their skills of using cell phones for learning. Similarly, the self-report showed that the trainee teachers themselves viewed the cell phones as helpful tools for teaching reading and listening despite some technical difficulties they faced. Finally, it was recommended that such working cases need to be expanded to other Ethiopian educational contexts and be embraced by as many schools as possible.

CUSTOMARY LAW ‘WOGA’: ITS MEANING, CHANGES AND CONTINUITY IN THE GAMO CONTEXT
Authors: Zelalem Zewdie  
Published: April 2023

This article is an attempt to explore the meaning, the changes and continuity on the customary law, ‘woga’ among the Gamo of southern Ethiopia. The article followed the tradition of an ethnographic approach. To explore the customary law, interviews and focus group discussions were conducted to explore the meaning, its role and the changes that ‘woga’ is facing. The data is analyzed and interpreted in relation to the literature. The meanings of ‘woga’ given by different social groups are discussed. Some cases were analyzed to show the significances of the customary law in the day-to-day lives of the study group. The data shows that the customary law is playing a significant role in resolving interpersonal, family and inter-group conflicts in a micro and macro level in parallel with the formal institution. The study also identified that the customary law has been facing various changes linked with migration and social evolutions that adversely affects its effectiveness and efficiency. Government should promote its continuity by providing the community conflict resilience through inclusive participation of all social groups and rediscovering elders wisdom.
Keywords: changes, continuity, customary law, Indigenous, woga.

Authors: Sprong K E , Wright C A , Mabenge M , Govender S 
Published: April 2023

Background. Preterm birth remains a global health concern and is one of the most common pregnancy complications associated with perinatal morbidity and mortality.Objective. To investigate placental pathology and its associations with obstetric, maternal and neonatal outcomes in the Eastern Cape region of South Africa (SA) in order to help understand its associations with preterm birth in that region.
Methods. In this prospective study, placentas were collected consecutively from patients attending a public tertiary referral hospital in SA, delivering preterm (n=100; 28 - 34 weeks gestational age) and term (n=20; >36 weeks gestational age). Placentas were submitted for histopathology, and comparisons with maternal characteristics and neonatal outcomes in preterm birth were undertaken.Results. Histological analysis revealed pathology in all preterm placentas (100%), with maternal vascular malperfusion (47%) and abruptio placentae (41%) most commonly identified. Acute chorioamnionitis (21%) was associated with term births (p=0.002). Maternal characteristics and neonatal outcomes significantly associated with preterm birth included pre-eclampsia (p=0.006), neonatal respiratory distress syndrome (p=0.004) and neonatal jaundice (p=0.003). Intrauterine demise (p=0.004) and alcohol abuse (p≤0.005) were significantly associated with term delivery. The number of mothers delivering preterm who were HIV-positive was high (41%).
Conclusion. The pathology identified in all preterm placentas supports the need to update institutional policies for submission of placentas from all preterm births for histopathology, particularly in countries with a high burden of preterm birth.
Disentangling the rhythms of human activity in the built environment for airborne transmission risk: An analysis of large-scale mobility data
Authors: Susswein Zachary , Rest Eva C , Bansal Shweta 
Published: April 2023

Background:Since the outset of the COVID-19 pandemic, substantial public attention has focused on the role of seasonality in impacting transmission. Misconceptions have relied on seasonal mediation of respiratory diseases driven solely by environmental variables. However, seasonality is expected to be driven by host social behavior, particularly in highly susceptible populations. A key gap in understanding the role of social behavior in respiratory disease seasonality is our incomplete understanding of the seasonality of indoor human activity.Methods:We leverage a novel data stream on human mobility to characterize activity in indoor versus outdoor environments in the United States. We use an observational mobile app-based location dataset encompassing over 5 million locations nationally. We classify locations as primarily indoor (e.g. stores, offices) or outdoor (e.g. playgrounds, farmers markets), disentangling location-specific visits into indoor and outdoor, to arrive at a fine-scale measure of indoor to outdoor human activity across time and space.Results:We find the proportion of indoor to outdoor activity during a baseline year is seasonal, peaking in winter months. The measure displays a latitudinal gradient with stronger seasonality at northern latitudes and an additional summer peak in southern latitudes. We statistically fit this baseline indoor-outdoor activity measure to inform the incorporation of this complex empirical pattern into infectious disease dynamic models. However, we find that the disruption of the COVID-19 pandemic caused these patterns to shift significantly from baseline and the empirical patterns are necessary to predict spatiotemporal heterogeneity in disease dynamics.Conclusions:Our work empirically characterizes, for the first time, the seasonality of human social behavior at a large scale with a high spatiotemporal resolutio and provides a parsimonious parameterization of seasonal behavior that can be included in infectious disease dynamics models. We provide critical evidence and methods necessary to inform the public health of seasonal and pandemic respiratory pathogens and improve our understanding of the relationship between the physical environment and infection risk in the context of global change.Funding:Research reported in this publication was supported by the National Institute of General Medical Sciences of the National Institutes of Health under award number R01GM123007.
The Growing Threat of Antibiotic Resistance: Addressing the Urgency

Published: April 2023

Antibiotic resistance has become a critical public health issue due to the overuse and misuse of antibiotics. Despite ongoing efforts to develop stronger antibiotics, bacterial resistance continues to evolve, leading to a global crisis. Effective antibiotics are becoming scarce, and diseases that were once treatable are now becoming uncontrollable. There is a need for new solutions to preserve the current antibiotic arsenal and combat bacterial resistance. Narrow-spectrum antibiotics which do not contribute to multidrug resistance could be a solution instead of broad-spectrum antibiotics.
One potential solution is phage therapy, which uses bacteriophages to target specific bacteria without harming healthy cells. Plants are another potential solution because they contain natural antibacterial compounds like polyphenols and alkaloids. Antimicrobial proteins (AMPs) from eukaryotes can also be a good substitute for antibiotics because they do not require a receptor and minimize the chance of bacterial resistance. A clinical trial on women with recurrent UTI was performed. The results of which revealed that overall methenamine hippurate is effective in reducing the intake of antibiotics. Whole genome sequencing is a rapidly evolving method through which resistance pathways are identified to tackle resistance. Developing metallophores is an area of great potential and metal complexes are more likely to advance towards becoming a clinically approved replacement to antibiotics. The development of new solutions is critical to prevent the spread of antibiotic-resistant bacteria and ensure that bacterial infections remain treatable.
Diagnosis and Treatment of Acute Myocarditis
Authors: Ammirati Enrico , Moslehi Javid J. 
Published: April 2023

ImportanceAcute myocarditis, defined as a sudden inflammatory injury to the myocardium, affects approximately 4 to 14 people per 100 000 each year globally and is associated with a mortality rate of approximately 1% to 7%.ObservationsThe most common causes of myocarditis are viruses, such as influenza and coronavirus; systemic autoimmune disorders, such as systemic lupus erythematosus; drugs, such as immune checkpoint inhibitors; and vaccines, including smallpox and mRNA COVID-19 vaccines. Approximately 82% to 95% of adult patients with acute myocarditis present with chest pain, while 19% to 49% present with dyspnea, and 5% to 7% with syncope. The diagnosis of myocarditis can be suggested by presenting symptoms, elevated biomarkers such as troponins, electrocardiographic changes of ST segments, and echocardiographic wall motion abnormalities or wall thickening. Cardiac magnetic resonance imaging or endomyocardial biopsy are required for definitive diagnosis. Treatment depends on acuity, severity, clinical presentation, and etiology. Approximately 75% of patients admitted with myocarditis have an uncomplicated course, with a mortality rate of approximately 0%. In contrast, acute myocarditis that is complicated by acute heart failure or ventricular arrhythmias is associated with a 12% rate of either in-hospital mortality or need for heart transplant. Approximately 2% to 9% of patients have hemodynamic instability, characterized by inability to maintain adequate end-organ perfusion, and require inotropic agents, or mechanical circulatory devices, such as extracorporeal life support, to facilitate functional recovery. These patients have an approximately 28% rate of mortality or heart transplant at 60 days. Immunosuppression (eg, corticosteroids) is appropriate for patients who have myocarditis characterized by eosinophilic or giant cell myocardial infiltrations or due to systemic autoimmune disorders. However, the specific immune cells that should be targeted to improve outcomes in patients with myocarditis remain unclear.Conclusions and RelevanceAcute myocarditis affects approximately 4 to 14 per 100 000 people per year. First-line therapy depends on acuity, severity, clinical presentation, and etiology and includes supportive care. While corticosteroids are often used for specific forms of myocarditis (eg, eosinophilic or giant cell infiltrations), this practice is based on anecdotal evidence, and randomized clinical trials of optimal therapeutic interventions for acute myocarditis are needed.

Published: April 2023

AbstractObjectivePhosphodiesterase‐5 inhibitors (PDE5Is) enhance vasodilation. We investigated the effects of PDE5I on cerebral hemodynamics during cognitive tasks using functional near‐infrared spectroscopy (fNIRS).MethodsThis study used a crossover design. Twelve cognitively healthy men participants (mean age, 59 ± 3 years; range, 55–65 years) were recruited and randomly assigned to the experimental or control arm, then the experimental and control arm were exchanged after 1 week. Udenafil 100 mg was administered to participants in the experimental arm once daily for 3 days. We measured the fNIRS signal during the resting state and four cognitive tasks three times for each participant: at baseline, in the experimental arm, and in the control arm.ResultsBehavioral data did not show a significant difference between the experimental and control arms. The fNIRS signal showed significant decreases in the experimental arm compared to the control arm during several cognitive tests: verbal fluency test (left dorsolateral prefrontal cortex, T = −3.02, p = 0.014; left frontopolar cortex, T = −4.37, p = 0.002; right dorsolateral prefrontal cortex, T = −2.59, p = 0.027), Korean‐color word Stroop test (left orbitofrontal cortex, T = −3.61, p = 0.009), and social event memory test (left dorsolateral prefrontal cortex, T = −2.35, p = 0.043; left frontopolar cortex, T = −3.35, p = 0.01).InterpretationOur results showed a paradoxical effect of udenafil on cerebral hemodynamics in older adults. This contradicts our hypothesis, but it suggests that fNIRS is sensitive to changes in cerebral hemodynamics in response to PDE5Is.

AbstractAqueous Zn‐ion energy‐storage deviceswith metal Zn as anodes, including batteries and capacitors (ZIBs and ZICs), is largely hindered by dendritic growth and low coulombic efficiency since the side reactions between Zn anodes and electrolyte, originating fromthat targeted and efficient isolation of H2O and SO42− is extremely challenging. Herein, inspired by density functional theory (DFT) that the 2D angstrom level metal‐organic framework(2D‐MOF) is highly selective for the passage of ions, simultaneously excluding the SO42− and H2O but allowing Zn2+ selective conduction. Moreover, 2D‐MOF exhibits better mechanical strength compared with 3D‐MOF, which is more conducive to inhibit dendrite growth. Impressively, benefiting from the 2D‐MOFlayer, symmetric Zn cells survived up to 2000 h at 4 mA cm−2,near 20‐times that of bare Zn anodes. Coupling it with cathode for ZICs and ZIBs, excellent electrochemical performances are presented. Importantly, symmetric Na cells with 2D‐MOF as ionic sieve membrane also deliver small polarization and outstanding performance, indicating that this study provides an efficient strategy to develop long‐life metal anode.

AbstractQuantum critical points separating weak ferromagnetic and paramagnetic phases trigger many novel phenomena. Dynamical spin fluctuations not only suppress the long‐range order, but can also lead to unusual transport and even superconductivity. Combining quantum criticality with topological electronic properties presents a rare and unique opportunity. Here, by means of ab initio calculations and magnetic, thermal, and transport measurements, it is shown that the orthorhombic CoTe2 is close to ferromagnetism, which appears suppressed by spin fluctuations. Calculations and transport measurements reveal nodal Dirac lines, making it a rare combination of proximity to quantum criticality and Dirac topology.

AbstractDer Pyridinring ist eine wichtige Kernstruktur für eine Vielzahl von Arzneimitteln, Agrochemikalien, Katalysatoren und funktionellen Materialien. Die direkte Funktionalisierung der C−H‐Bindung in Pyridinen ist ein einfacher und direkter Ansatz, um substituierte Pyridine zu erhalten. Im Vergleich zur direkten ortho‐ und para‐Funktionalisierung ist die meta‐selektive C−H‐Funktionalisierung von Pyridinen aufgrund der inhärenten elektronischen Eigenschaften der Pyridineinheit weitaus schwieriger. Dieser Übersichtsartikel fasst die derzeit verfügbaren Methoden zur meta‐C−H‐Funktionalisierung von Pyridinen unter Verwendung dirigierender Gruppen, ungerichteter Metallierung und temporärer Dearomatisierungsstrategien zusammen. Die jüngsten Fortschritte bei der Ligandenkontrolle und der temporären Dearomatisierung werden hervorgehoben. Wir analysieren sowohl die Vorteile als auch die Grenzen der aktuellen Strategien und hoffen, weitere Entwicklungen auf diesem wichtigen Gebiet anzuregen.
