A NOVEL FAULT TOLERANT ASYMMETRICAL 21-LEVEL INVERTER TOPOLOGY WITH REDUCED COMPONENTS
Authors: RAGUL DURAISAMY , THIYAGARAJAN VENKATRAMAN 
Published: August 2023

The foremost objective of this work is to propose a fault-tolerant (FT) asymmetrical 21-level inverter with minimal power semiconductor switches and voltage sources. The topology of the proposed inverter is to produce high voltage levels with low harmonic content and minimize electromagnetic interference (EMI) in the system. Meanwhile, the novelty has been proved by a detailed comparison between the suggested multilevel inverter (MLI) and recently introduced topologies using several components such as switches, capacitors, sources, gate driving circuits, total standing voltage (TSV), component count per level and cost function. Additionally, the flexible circuit connection between sources, switches, and loads provides the alternative configuration for 21-level MLI to operate as a 9-level and 7-level MLI topology, ensuring FT capability during the failure of specific sources and switches. The nearest voltage level (NVL) algorithm technique produces gate driver signals for the switches, which generate high-quality waveform compared to other pulse width modulation (PWM) techniques. A simulation model is designed to support the simulation results using MATLAB/Simulink software and hardware implementation. The results are analyzed under different combinations of linear and nonlinear loads. In both simulation and experiment, the evaluated parameter values show good performance concerning other structures, and total harmonic distortion (THD) is less than 5 % as per IEE519 standards.

El conocimiento didáctico del contenido sobre las actividades prácticas de laboratorio por indagación de profesores de Biología
Authors: Fernandez Nancy 
Published: August 2023

Al diseñar una actividad práctica de Laboratorio es importante definir qué relaciones se pretende que el alumnado llegue a establecer entre los resultados del mismo y los conocimientos teóricos. Independientemente del enfoque o de los contenidos abordados, las actividades prácticas suponen la realización de distintos tipos de actividades relacionadas, que constituyen ayudas fundamentales para promover la construcción de nuevos conocimientos. Resulta fundamental que estudiantes tengan ocasión de participar en la elaboración de diseños experimentales, en vez de seguir guías detalladas ya preparadas por docentes, dado el papel central que juega el diseño en la investigación y, muy en particular, para que adquieran una visión válida de las relaciones ciencia-tecnología- sociedad. También se destaca la importancia de las actividades de laboratorio por su carácter motivacional del aprendizaje. Sin embargo, se cuestiona la motivación y se la diferencian del interés, ya que, si bien ciertas actividades prácticas pueden generar interés dentro de un contenido en particular, hay pocas evidencias que sugieran que las actividades de laboratorio motiven los y las alumnas hacia la Ciencia en general o, hacia el estudio de una Ciencia en particular. El interés situacional hace referencia al que se estimula en un individuo como consecuencia de estar en un ambiente o situación particular, como cuando un alumno o alumna realiza un trabajo práctico dentro de un Laboratorio de Ciencias. A diferencia del interés personal, el situacional es susceptible a la influencia de su docente a corto plazo.
Aunque es menos probable que persista con el tiempo, proporciona una oportunidad para que el profesorado influya positivamente en la eficacia del aprendizaje del estudiantado en contenidos específicos.
En el proceso investigativo, algunas ideas, argumentaciones, conjeturas, discusiones, análisis de datos, fueron volcadas en artículos que se publicaron durante 2017 y 2018 en revistas académicas. Al momento de escribir, los artículos pasaron a conformar capítulos de la Tesis, hilvanando la producción en un continuo que da cuenta de las indagaciones realizadas para la construcción del objeto de estudio.

Published: August 2023

ABSTRACT

BACKGROUND:
Sleep disturbances are common in individuals with multiple sclerosis. The objective of this systematic review was to determine effective behavioral interventions to improve their sleep.

METHODS:
Literature searches were performed in December 2021 in Ovid MEDLINE, Elsevier Embase, and Web of Science, along with hand searching for grey literature and cited references. Four reviewers independently reviewed titles and abstracts (2 reviewers for each article; n = 830) and the full-text articles (n = 81). Consensus for inclusion was achieved by a fifth reviewer. Thirty-seven articles were eligible for inclusion. Four reviewers extracted relevant data from each study (2 reviewers for each article) using a standard data extraction table. Consensus was achieved for completeness and accuracy of the data extraction table by a fifth reviewer. The same 4 reviewers conducted a quality appraisal of each article to assess the risk of bias and quality of the articles, and consensus was achieved by a fifth reviewer as needed. Descriptive data were used for types of interventions, sleep outcomes, results, and key components across interventions.

RESULTS:
Overall, the cognitive behavioral therapy for insomnia, cognitive behavioral therapy/psychotherapy, and education/self-management support interventions reported positive improvements in sleep outcomes. Quality appraisal scores ranged from low to high, indicating potential for bias.

CONCLUSIONS:
Variability in the intervention type, intervention dose, outcomes used, training/expertise of interventionist, specific sample, and study quality made it difficult to compare and synthesize results. Further research is necessary to demonstrate the efficacy of most of the interventions.

Objectives
Jumping ability has been identified as a key factor that influences the performance of badminton athletes. Autoregulatory progressive resistance exercise (APRE) and velocity-based resistance training (VBRT) are commonly used approaches to enhance muscle strength and have been shown to accurately monitor the development of explosive power to improve jumping ability. This study aims to investigate the effects of APRE and VBRT on badminton athletes’ jumping ability and to provide practical insights into improving their jumping performance during competitions.

Methods
Upon completing familiarization and pretesting, 18 badminton athletes were included and completed the training intervention (age, 21.4 ± 1.4 years; stature, 170.1 ± 7.3 cm; body mass, 65.9 ± 12 kg); they were randomly divided into the APRE group (n = 9) and VBRT group (n = 9). Jumping performance was assessed during the countermovement jump (CMJ), squat jump (SJ), and drop jump (DJ) via SmartJump, with CMJ ’s and SJ’s jump height, eccentric utilization ratio (EUR), and reactive strength index (RSI). All participants then completed a 4-week in-season resistance training intervention.

Results
(1) The results of the within-group indicated that only the CMJ (pre: 41.56 ± 7.84 vs post: 43.57 ± 7.85, p < 0.05) of the APRE group had significant differences, whereas the SJ, EUR, and RSI were not significantly different (p > 0.05). (2) The results of the intergroups revealed that all indicators had no significant differences (p > 0.05), but APRE had a moderate effect size on the improvement of the CMJ (η2 = 0.244) and EUR (η2 = 0.068) when compared with VBRT.

Conclusions
The results showed that, compared to VBRT, APRE can effectively improve the performance of the reactive athletes’ lower limb explosive power in the CMJ in a shorter period of time. The findings indicate that APRE may be useful for coaches seeking to improve the CMJ performance of athletes in the short term.

Published: August 2023

Background: Wetlands serve as breeding grounds for mosquitoes, the vector of malaria Plasmodium. Effective detection of Plasmodium infection requires a very sensitive method.
Aim: The aim of the present study was to evaluate the prevalence of malaria parasite infection in Sagbama LGA, Bayelsa State using nested PCR and high resolution melting analysis (HRMA) technique in comparison with microscopy.
Methods: A community based cross sectional study design was employed to randomly select 206 study participants. DNA was extracted from 200 ⴗl of whole blood of each participant and a set of primers was used to target and amplify the 18S rRNA gene of Plasmodium falciparum in both molecular methods.
Result: The prevalence of Plasmodium falciparum infection by microscopy was 33.01% (5.8% asymptomatic, 17% mild and 10.2% severe malaria).The prevalence of malaria parasite infection by nested genomic PCR was 71.36% (asymptomatic, 42.20% mild, 18.93%and severe malaria, 10.19%). Prevalence of malaria parasite infection by high resolution melting analysis 92.71% (asymptomatic, 63.59%, mild, 18.93% and severe, 10.19%). All the study participants that were positive for microscopy and nested genomic PCR were also positive for high resolution melting analysis. There were 59.71% and 21.36% false negatives by microscopy and nested PCR respectively. McNemar`s test for pair-wise performance comparisons among the different methods was statistically significant (p < 0.001). High parasite density (19927 ± 749 parasites/µl blood) and hyper parasite density (103667 ± 5214 parasites/ⴗl of blood) were found among asymptomatic and severe malaria subjects (P < 0.000).
Conclusion: In conclusion, a high malaria parasite infection prevalence of 92.72% was found in Sagbama LGA. This requires urgent attention especially asymptomatic malaria. HRMA was the most sensitive molecular method and is therefore recommended for future molecular detection of malaria infection.
A case report on the effects of COVID-19 on ANC monitoring in a patient on long-term clozapine treatment
Authors: Denton Lauren , Kapuganti Amber , Kim Sarah 
Published: August 2023

Abstract

Background
Clozapine carries a US boxed warning for severe neutropenia, and strict monitoring is required through the FDA's Risk Evaluation and Mitigation Strategy (REMS) program. Patients with confirmed diagnosis of COVID-19 are also at risk for neutropenia. For patients on clozapine, the diagnosis of this novel virus may require an increase in the frequency of scheduled ANC monitoring. A case report of moderate neutropenia following COVID-19 diagnosis that required an increase in the frequency of ANC monitoring in a patient on long-term clozapine treatment is discussed.

Case Report
A 33-year-old white man with schizophrenia had been on clozapine for more than 2 years, with an ANC monitoring schedule once every 4 weeks. The patient was admitted to the hospital for worsening aggressive behavior. On day 11 of hospital admission, he tested positive for COVID-19. Five days following this diagnosis, the patient's ANC dropped from 2.2/L to 0.8/L. This decrease led to daily ANC labs and the clozapine regimen being held for 1 day. Throughout the patient's admission adjustments were made to the frequency of lab monitoring based on fluctuations in his ANC levels.

Discussion
There have been limited case reports on patients receiving clozapine experiencing neutropenia following the diagnosis of COVID-19. To the authors knowledge, this is the first case report from the United States that specifically discusses the required changes to ANC monitoring.

Conclusions
Patients on clozapine who test positive for COVID-19 may be at an even greater risk for neutropenia, compared with clozapine patients without COVID-19. Increasing the frequency of ANC monitoring should be considered in the weeks following the diagnosis to ensure that clozapine treatment can be safely adjusted, or even discontinued.
Revisiting scale invariance and scaling in ecology: River fractals as an example
Authors: Terui Akira 
Published: August 2023

AbstractScale invariance, which refers to the preservation of geometric properties regardless of observation scale, is a prevalent phenomenon in ecological systems. This concept is closely associated with fractals, and river networks serve as prime examples of fractal systems. Quantifying river network complexity is crucial for unveiling the role of river fractals in riverine ecological dynamics, and researchers have used a metric of “branching probability” to do so. Previous studies showed that this metric reflects the fractal nature of river networks. However, a recent article by Carraro and Altermatt (2022) contradicted this classical observation and concluded that branching probability is “scale dependent.” I dispute this claim and argue that their major conclusion is derived merely from their misconception of scale invariance. Their analysis in the original article (fig. 3a) provided evidence that branching probability is scale‐invariant (i.e., branching probability exhibits a power‐law scaling), although the authors erroneously interpreted this result as a sign of scale dependence. In this article, I re‐introduce the definition of scale invariance and show that branching probability meets this definition. This provided an opportunity to address the divergent use of “scale invariance” and “scaling” between fractal theory and ecology.

Published: August 2023

AbstractObjectiveAssessing severity of antibody‐mediated encephalitis (AE) or paraneoplastic encephalitis (PE) requires valid and reliable scores to guide treatment decisions and predict outcome both in clinical routine and studies. We aimed to validate the prognostic value of the clinical assessment scale in autoimmune encephalitis (CASE) and the anti‐NMDAR‐encephalitis one‐year functional status (NEOS) score in patients suffering from AE and PE in a large monocentric cohort.MethodsWe retrospectively applied the CASE and NEOS score to patients with definite AE and PE treated at a tertiary hospital. Correlations were established between the CASE and NEOS score and the modified Rankin scale (mRs). Multivariable analyses were calculated to identify predictors of outcome.ResultsThirty‐four patients (27 AE, 7 PE) were included. Correlations between mRS and CASE score were strongest in patients with AE compared to PE at all intervals, but in the subgroups (LGI1, NMDAR, GAD, miscellaneous surface antibodies, PE) the correlation was strongest in the interval after baseline. Patients with AE seemed to display better outcomes compared to PE, which was underlined by multivariable analysis. Improvement was mostly observed within 6–12 months after disease onset, after which little or no further improvement was noted with some exception for two patients with anti‐NMDARE who recovered substantially even after 12 months of treatment. The NEOS score significantly predicted the outcome at last follow‐up in patients with AE with a sensitivity of 79% at a cut‐off value of 2 points (AUC 0.79, 95% CI 0.58–0.99, p = 0.04).InterpretationThe CASE and NEOS score are suitable supplementary tools in addition to the mRS for capturing diverse symptoms, for grading and monitoring symptom severity.
Learning from feedback in college courses: Student beliefs, practices, and preferences
Authors: Zepeda Cristina D. , Ortegren Francesca R. , Butler Andrew C. 
Published: August 2023

AbstractStudents receive different types of task‐ and process‐level feedback in educational settings, but it is unclear how they perceive and use these different types of feedback they receive. In a broad and representative survey, 378 students answered questions about their experiences with feedback in college courses, their perceptions of the feedback, and the regulatory and motivational strategies they used to learn from it. On average, students reported receiving feedback on three different types of tasks in a course and the nature of the feedback differed by task. Although some student practices in processing feedback were uniform across types of tasks and feedback, other practices varied markedly. Students reported that they highly valued all feedback, but believed its utility declined over time and preferred immediate feedback. This study provides novel insights into student beliefs and preferences regarding feedback and the regulatory and motivational practices that they use to learn from feedback.
Unlocking Efficient High‐Order Multiphoton‐Excited Fluorescence of Metal‐Organic Framework via Octupolar Module In Situ Formation

Published: August 2023

AbstractEngineering high‐order multiphoton excited fluorescent (H‐MPEF) materials is of significant importance for sensing, 3D optical data storage and bioimaging. However, it remains a challenging endeavor due to a lack of appropriate construction strategies. This study demonstrates that incorporating octupolar modules within metal‐organic framework (MOF) offers new possibilities for the design of highly attractive H‐MPEF materials. Constructed from a typical MOF (UiO(bpdc)), the in situ formation of multibranched octupolar cyclometallated iridium(III) modules via post‐ligand coordination modification endowed the framework with enlarged static hyperpolarizabilities, an extended conjugated system, and enhanced charge transfer, ultimately unlocking its second near‐infrared (NIR‐II, 1000–1700 nm) light activated H‐MPEF performance including three‐ and four‐photon activity. Moreover, these exciting features, combined with subsequent orotic acid‐capping, enabled its application in cancer cell‐specific targeting oncotherapy using tissue‐penetrating NIR‐II light. This finding highlights the vital role of octupoles in H‐MPEF performance and sets a benchmark for unlocking the multiphoton activity of MOFs at the molecular level for deep‐seated tumor fluorescence imaging and therapy.
Carboxylate‐Containing Poly(thiophene vinylene) Derivative with Controlled Molecular Weights for High‐Performance Intrinsically‐Stretchable Organic Solar Cells
Authors: Lee Jin‐Woo , Phan Tan Ngoc‐Lan , Oh Eun Sung , Lee Heung‐Goo , Kim Taek‐Soo , Kim Bumjoon J. 
Published: August 2023

AbstractOwing to their simple chemical structures and straightforward synthesis, poly(thiophene vinylene) (PTV) derivatives are promising types of polymer donors for organic solar cells (OSCs). However, the structural rigidity of PTVs results in the formation of films with poor mechanical properties, which limits the application of PTVs in intrinsically stretchable (IS)‐OSCs. Here, new carboxylate‐containing PTVs are developed with tuned molecular weight (MW) (PETTCVT‐X, X = L, M, and H) and realize efficient and mechanically durable IS‐OSCs. The crystallinity of the PTVs increases progressively with increasing MW, leading to enhanced hole mobility and suppressed charge recombination of the OSCs. Moreover, both the mechanical stretchability and electrical properties of the PTVs increase significantly with increasing MW, owing to the formation of tie‐chains that connect the isolated crystalline domains. Consequently, OSCs featuring a PTV with the highest MW (PETTCVT‐H) exhibit the highest power conversion efficiency (PCE, 15.3%) and crack‐onset strain (COS, 7.1%) among the series, compared to lower values for the PETTCVT‐L (PCE = 9.7% and COS = 1.3%) and PETTCVT‐M‐based OSCs (PCE = 12.5% and COS = 3.7%). Therefore, the IS‐OSCs employing PETTCVT‐H present the highest initial PCE (10.1%) and stretchability (strain at PCE80% (retaining 80% of the initial PCE) = 16%).
