Tuning the Band Gap in the Halide Perovskite CsPbBr3 Through Sr Substitution
Authors: Straus Daniel , Cava Robert
Published: May 2022

The ability to continuously tune the band gap of a semiconductor allows its optical properties to be precisely tailored for specific applications. We demonstrate that the band gap of the halide perovskite CsPbBr3 can be continuously widened through homovalent substitution of Sr2+ for Pb2+ using solid-state synthesis, creating a material with the formula CsPb1-xSrxBr3 (0 ≤ x ≤ 1). Sr2+ and Pb2+ form a solid solution in CsPb1-xSrxBr3. Pure CsPbBr3 has a band gap of 2.29(2) eV, which increases to 2.64(3) eV for CsPb0.25Sr0.75Br3. The increase in band gap is clearly visible in the color change of the materials and is also confirmed by a shift in the photoluminescence. Density-functional theory calculations support the hypothesis that Sr incorporation widens the band gap without introducing mid-gap defect states. These results demonstrate that homovalent B-site alloying can be a viable method to tune the band gap of simple halide perovskites.

Localized Active Space State Interaction: A Multireference Method For Chemical Insight
Authors: Pandharkar Riddhish , Hermes Matthew R. , Cramer Christopher J. , Gagliardi Laura
Published: May 2022

Multireference electronic structure methods, like the complete active space (CAS) selfconsistent field model, have long been used to characterize chemically interesting processes. Important work has been done in recent years to develop modifications having lower computational cost than CAS, but typically these methods offer no more chemical insight than that from the CAS solution being approximated. In this paper, we present the localized active space - state interaction (LASSI) method that can be used not only to lower the intrinsic cost of the multireference calculation, but also to improve interpretability. The localized active space (LAS) approach utilizes the local nature of electron-electron correlation to express a composite wave function as an antisymmetrized product of unentangled wave functions in local active subspaces. LASSI then uses these LAS states as a basis from which to express complete molecular wave functions. This not only makes the molecular wave function more compact, but it also permits flexibility in choosing those states to include in the basis. Such selective inclusion of states translates to selective inclusion of specific types of interactions, thereby allowing a quantitative analysis of these interaction. We demonstrate the use of LASSI to study charge migration and spin-flip excitations in multireference organic molecules. We also compute the J coupling parameter for a bimetallic compound using various LAS bases to construct the Hamiltonian to provide insight into the coupling mechanism.
Gradient bundle analysis of ketosteroid isomerase
Authors: Wilson Timothy , Morgenstern Amanda , Alexandrova Anastassia , Eberhart Mark
Published: May 2022

Bond bundle analysis is used to investigate enzymatic catalysis in the KSI active site. We identify the unique bonding regions in five KSI systems, including those exposed to applied oriented electric fields and those with amino acid mutations, and calculate the precise redistribution of electron density that accompanies either enhancement or inhibition of KSI catalytic activity. In two examples—using direct inspection of bond bundle regional properties, and using correlations between those properties and reaction barrier height—we arrive at similar conclusions, that catalytic enhancement results from promoting electron density redistribution between bonds within the KSI-docked substrate molecule in a way that closely resembles our mechanistic understanding of the forward catalyzed reaction. The catalyzing charge redistribu- tion between bond bundles is prevalent in KSI systems catalyzed via electric fields or via amino acid mutation, and are thus suggestive of a general catalytic role.
An extended binary subband canonical correlation analysis detection algorithm oriented to the radial contraction-expansion motion steady-state visual evoked paradigm
Authors: Zhao Yuxue , Zhang Hongxin , Wang Yuanzhen , Li Chenxu , Xu Ruilin , Yang Chen
Published: May 2022

The radial contraction-expansion motion paradigm is a novel steady-state visual evoked experimental paradigm, and the electroencephalography (EEG) evoked potential is different from the traditional luminance modulation paradigm. The signal energy is concentrated chiefly in the fundamental frequency, while the higher harmonic power is lower. Therefore, the conventional steady-state visual evoked potential recognition algorithms optimizing multiple harmonic response components, such as the extended canonical correlation analysis (eCCA) and task-related component analysis (TRCA) algorithm, have poor recognition performance under the radial contraction-expansion motion paradigm. This paper proposes an extended binary subband canonical correlation analysis (eBSCCA) algorithm for the radial contraction-expansion motion paradigm. For the radial contraction-expansion motion paradigm, binary subband filtering was used to optimize the weighting coefficients of different frequency response signals, thereby improving the recognition performance of EEG signals. The results of offline experiments involving 13 subjects showed that the eBSCCA algorithm exhibits a better performance than the eCCA and TRCA algorithms under the stimulation of the radial contraction-expansion motion paradigm. In the online experiment, the average recognition accuracy of 13 subjects was 88.68% ± 6.33%, and the average information transmission rate (ITR) was 158.77 ± 43.67 bits/min, which proved that the algorithm had good recognition effect signals evoked by the radial contraction-expansion motion paradigm.
Trends in Aortic Occlusion and How to Minimize the Risk of Complications in REBOA
Authors: Matsumura Yosuke , Funabiki Tomohiro
Published: May 2022

Resuscitative endovascular balloon occlusion of the aorta (REBOA) increases proximal aortic pressure in order to maintain central organ perfusion pressure, and simultaneously regulates distal arterial flow by endovascular aortic occlusion, which is applied during subdiaphragmatic hemorrhage. This article briefly introduces the history of REBOA and discusses its potential effectiveness and harmfulness. The article also mentions the technical aspects of REBOA, and reconsiders the term “REBOA” and “resuscitation.” The risks of aortic occlusion and ischemia-reperfusion injury have not been fully elucidated. It is hoped that REBOA can be used appropriately as a powerful option for the resuscitation of hemorrhagic patients and save the lives of as many patients as possible. The Society of Diagnostic and Interventional Radiology in Emergency, Critical Care, and Trauma will publish continuous medical education articles on REBOA.
“When I tell them my caste, silence descends”: Caste-based Discrimination among the Nepali Diaspora in the San Francisco Bay Area, USA
Authors: Pariyar Prem , Gupta Bikash , Fonseka Ruvani W
Published: May 2022

Recent cases of caste-based workplace discrimination in Silicon Valley in the United States (US) have highlighted the practice of caste-based discrimination in the San Francisco (SF) Bay Area. Most documentation of caste-based discrimination in diaspora populations in the US has focused on the Indian diaspora, omitting the perspectives of Dalits from other South Asian countries. This study investigated caste-based discrimination among the Nepali diaspora living in the SF Bay Area. Twenty-seven Nepali-American Dalits in the SF Bay Area participated in qualitative research on their experiences of caste-based discrimination. Aligned with findings from studies of Dalit diaspora members in other settings, the research found that Dalits faced social exclusion, workplace prejudice, microaggressions, and housing bias in the Nepali diaspora in the SF Bay Area. To preempt or avoid discrimination, some Dalits hid their caste, and many did not feel comfortable taking action regarding caste-based discrimination because of the absence of caste as a protected category in their workplaces and in local government policies. Caste-based discrimination affected the Dalits’ mental health as well. The findings highlight the need for policy interventions for Dalits living in the SF Bay Area and facing caste-based discrimination within their diaspora communities.
Conceptions of Community, Nation and Politics: The Ezhavas of South Malabar, India and their Quest for Equality
Authors: K Anish K
Published: May 2022

This article discusses caste reforms, anti-caste ideas, and thoughts on nationalism amongst Ezhavas of South Malabar in the Madras Presidency. The discourses of equality, the right to the public, the process of community formation, ideology, and the mode of struggle for emancipation are examined. The question of caste, by what means the aspirations of the lower castes were addressed in the uniting project of reformed Hinduism and nationalism is addressed. By capturing disagreements, conflicts, consensus, and the politics of ‘sub-nationalities’ within the ‘national,’ the generic view of national movement as a single, homogeneous consensus project is contested. Towards the end, the article contends that Ezhavas’ assertions imply the presence of an “autonomous anti-caste movement” in the South Malabar region. This article also proposes that the dichotomy of colonialism versus nationalism, and the portrayal of South Indian politics as a sectarian competition for British patronage, limits the opportunity to comprehend localised movements and their vernacular expressions.

Authors: Işık Meryem Türkan , Can Özdemir Rana , Karadeniz Elif
Published: May 2022

Protecting the health and safety of nurses and other health professionals taking an active role during the COVID-19 pandemic is important. Risks not understood by health professionals and inadequate working conditions cause concern and lead to ethical problems. This qualitative research study was conducted to gain an understanding of the difficulties and emotions nurses experience, and their awareness of the ethical problems experienced while providing nursing care in the COVID-19 clinic. Data was collected by two different methods; deep conversation and semi-structured interview and evaluated by content analysis. Using an empirical phenomenological approach, data analysis concluded with two main themes and eight sub-themes. The average age of the nurses is 32.8±6.7, 91.1%  are female, 73.3%  have a bachelor's degree. Average weekly work hours before COVID-19 pandemic was 43.3± 4.6, after the pandemic 37.8± 5.5, 86.7% expressed that the care patients with COVID-19 received was adequate. The emotions experienced by the participants are positive, negative and ambivalent. During the COVID-19 outbreak, nurses were dominated by negative emotions intensified with the ethical issues surrounding the safety of patients, colleagues, families and themselves. Nurses primarily experience ethical problems related to their, patients’, colleagues’ and families’ safety. Positive emotions expressed by nurses; hopefulness, heroism, joy and success because of the patients' recovery, respect and emotions of gratitude. Some of the difficulties experienced by the participants are difficulties in care due to protective gear worn, difficulty reaching the physician and communication problems. Different studies can be planned regarding the factors affecting healthcare professional-patient communication during the COVID-19 care and treatment process.

Published: May 2022

This study aimed to draw attention to sadness and ensure that the sense of sadness experienced by nurses during the COVID-19 pandemic is noticed. During the pandemic, the sadness of nurses who have the most and close contact with patients should be evaluated. Support programs that would increase psychological resilience should be implemented for them to experience sadness at the lowest levels possible. If healthcare system managers improve the conditions that lead to nurses experiencing sadness and provide the necessary support to them, nurses will feel safe and perform their jobs willingly and enthusiastically.

A study was done on 385 people who survived from COVID 19 to assess the prevalence, symptom, and severity of COVID 19 of permanent residents of Dhaka city, Bangladesh during the second wave of corona manifestation. Data were collected purposively from a government and a private hospital, and general people taking treatment from home. A significant number of respondents took treatment from the Hospital during 2nd wave of COVID 19. Two-third of participants endured moderate (67.5%) type of suffering followed by mild (18.7%) and severe (13.8%) type of suffering. Most of the participants were married (88.8%) and female (51.2%). There was no significant difference between females and males suffering and the risk and severity of COVID 19 (p=694). Most of the participants (70%) had comorbidity. Time to recover from symptoms had significant relation with symptom patterns. One-third of the respondents (33%) required 4-7 days to recover from suffering. A little higher than a quarter (27.8%) recovered within 8 to 14 days and more than a quarter 105 (27.3%) recovered by 8-12 days respectively. Most of the respondents had a fever, cough, body ache and fatigue, sore throat, and breathing difficulty. Only (7.3%) had diarrhea (3.9%) and smell loss 13 (3.4%). People of permanent residence of Dhaka city suffered from COVID 19 irrespective of sex, education, professional status. They had comorbidity, required 8-14 days of hospitalization, and endured the moderate type of suffering of COVID-19.
Reciprocal regulation of glycogen synthase kinase-3 and β-catenin affects cell proliferation of fructose treated rat hepatocytes
Authors: Sadi Gökhan , Bostancı Aykut
Published: May 2022

High consumption of fructose might lead to obesity, diabetes, and metabolic syndrome in the long term. Recent studies demonstrated the induction of insulin resistance in the liver tissues by down-regulation of insulin signaling pathway elements. Glycogen synthase kinase-3 (GSK-3), one of the insulin signaling elements, suppresses the β-catenin function that is required for cell proliferation and integrity. This study is designed to demonstrate the effects of fructose on the proliferation of rat hepatocytes and its effects on GSK-3 and β-catenin expression. Accordingly, rat hepatocytes were treated with different concentrations of fructose, and cell proliferation was followed with an xCELLigence real-time cell analysis system. Besides, gene and protein expression levels of GSK3β and β-catenin were evaluated in fructose-treated cells with qRT-PCR and Western blot, respectively. The results demonstrated proliferative effects of fructose at low doses (0-25-50 mM), but cytotoxic properties are pronounced at higher doses (100-150 mM). The IC50 value was calculated as 140±7 mM fructose for Clone-9 cells. Molecular effects of fructose over GSK-3β and β-catenin appeared at gene and protein levels at 100- and 150-mM concentrations at which GSK-3β were suppressed. Conversely, high-dose fructose leads to β-catenin induction as a compensatory mechanism to counteract the antiproliferative effects of fructose at these doses. In conclusion, high-dose fructoseinduced cytotoxicity activates a compensatory molecular mechanism involving β-catenin induction which might protect the cells in the long-term fructose exposure

Student Access to and Competence in Migrating to a Fully Online Open Distance Learning Space
Authors: Kelebogile Mudau Patience , Biccard Piera , M van Wyk Micheal , J Kotze Christy , R Nkuna Victor
Published: May 2022

Aim/Purpose: This article aimed to explore student perceptions and experiences of migrating to a fully online mode during COVID-19.

Background: The COVID-19 pandemic changed the mode of delivery from face-to-face or blended learning to fully distance learning. The introduction of the Disaster Management Act (2020) in South Africa forced all institutions of learning to close their doors and move to teaching and learning online. We, therefore, needed to investigate whether the students at an Open Distance Learning (ODL) institution had access to the necessary devices and to see how they responded to fully online learning. Subsequently, this prompted a need to investigate student access to and competence in online learning in a fully ODL space during COVID-19. Since COVID-19 is a recent occurrence, little is known about how students experienced a (forced) move to fully online learning. In South Africa specifically, much less is known about fully online learning.

Methodology: The structured web-based survey was sent to all registered Bachelor of Education and Postgraduate Certificate in Education students. The structured questionnaire asking questions about students’ access to devices and their experiences of learning in a fully online mode, was administrated through Google Survey forms. There were 2,858 responses received. Descriptive statistics and exploratory factor analysis were used to uncover findings.

Contribution: This paper sets out student teachers’ experiences of learning in a fully online mode during COVID-19 in a developing country such as South Africa. These experiences as representative of the global South, are previously unknown to scholars and can assist in designing future fully online programs in this context.

Findings: Access to affordable data is an obstacle for students to access the learning management system. Students felt that the university took a long time to distribute laptops and also indicated that they lacked a suitable and stable internet connection. The digital divide was made more apparent and significant during COVID-19 although students indicated that they did develop necessary digital competencies.

Recommendations for Practitioners: Practitioners in Open Distance Learning should understand students’ context regarding access to tools and connectivity when designing courses.

Recommendation for Researchers: Researchers should explore theoretical framings to understand issues related to online education when access to tools and connectivity is limited.

Impact on Society: The digital divide was exacerbated by COVID-19. Students and communities need support to move to online modes of engagement.

Future Research: More studies of a qualitative and mixed-method nature should be conducted to fully understand student teachers’ context and challenges with online learning. Further research that includes student responses using non-digital means needs to be explored.

Published: May 2022

Society’s attitudes towards LGBT can be understood through college students’ viewpoints as the university’s environment can act as a microcosm of a larger community. Their voices can act as a representation of the youth generation and fellow citizens’ tolerance. This study aims to analyze the influences of religiosity and family gender roles socialization on students’ attitudes toward LGBT. Primary data used in this study were collected through an online questionnaire filled by 60 respondents, divided into male and female, who were selected by multistage random sampling technique involving all IPB’s undergraduate programs. This study found a significant difference between male and female students’ rejection of lesbians, with female students having higher rejection than male students. Students' religiosity and family gender roles socialization are in the medium category. Sex positively correlated to attitudes toward lesbians, while the mother's Occupation positively correlated to family gender roles, socialization, and religiosity was found to positively correlate with attitudes toward lesbians, gays, bisexuals, and transgender. Sex, explicitly being female, positively influences attitudes toward lesbians. In contrast, religiosity positively influences attitudes toward lesbian, gay, bisexual, and transgender, which means female students have a higher rejection of lesbians. The greater religiosity will result in increased rejection of LGBT.

Sexual orientation deviation is one of the problems often found in adolescents today. Sexual orientation in adolescents is one of the critical components in adolescent development because it involves adolescents' identity, interests, and sexual behaviour when will enter adulthood. Deviations Within the boundaries of the ideology and culture of the nation, this deviation from sexual orientation will cause developmental disorders in adolescents, and it is necessary to identify the root of the problem so that we can take preventive action. This study aimed to analyze the condition of student sexual orientation and further analyze its relationship with family characteristics, student characteristics, parenting styles, and peer attachment. This research is quantitative research with a survey method. The examples in this study were 272 students of the Vocational School of the Bogor Agricultural University who had complete parents with a proportion of 182 women and 90 men. The sampling technique used in this research is purposive sampling. The correlation test results showed that the sex of students and family size were related to sexual orientation. G that parenting style on the dimensions of rejection and coercion is related to sexual orientation. In addition, peer attachment to the dimension of alienation relates to student sexual orientation. Negative parenting styles and peer attachment have a relationship with sexual orientation. Therefore, parents should avoid negative parenting styles and control their children's environment so that sexual orientation deviations do not occur. Negative parenting styles in rejection, chaos and parental coercion tend to be associated with deviations in student sexual orientation. Likewise, the dimension of a perceived alienation from peer relationships also relates to student sexual orientation deviations.

Violence is a case that teenagers often experience, and violence cases in Indonesia are increasing every year. This study aims to analyze how adolescent and family characteristics and parenting styles influence sexual violence in adolescents. The research design used a cross-sectional study, followed by 45 young women who had experienced sexual violence in several provinces in Indonesia. The data collection technique used voluntary sampling using google-form, distributed through social media. This study uses the Parental Acceptance Rejection (PARQ) and Child Sexual Abuse (CSA). The results showed that adolescents who experienced violence were in the age range of 13 to 18 years. Teenage fathers primarily work as labourers, and mothers do not work/IRT. Parental marital status in general, living in their own home and residing in rural areas. The style of acceptance, aggression, neglect, and rejection of parents is low. However, sexual violence against adolescents is severe, with the most frequent perpetrators of violence perpetrated by their peers. The results showed that parents whose status was married had a rejection style of parenting, and teenagers who did not have their bedroom felt more cared for. Adolescents who live with nuclear families and receive an accepting parenting style from their parents are less likely to experience sexual violence.

Authors: Mahardika Tio Putra , Yuliati Lilik Noor
Published: May 2022

Consumer education interventions through formal education can increase knowledge, attitudes, and behaviour to become smart consumers who can enforce their rights, carry out their obligations, and protect themselves from harmful goods or services. This study aims to analyze differences in awareness of consumer education materials, sources of information, attitudes, and behaviour as savvy consumers in high school students in rural and urban Bogor and the factors that influence smart consumer behaviour. This study used a cross-sectional study design and involved two senior high schools located in the rural and urban areas of Bogor. The location selection was performed purposively, considering that the school implemented the Education Unit Level Curriculum (KTSP) and used the Electronic School Book (BSE). The sampling technique used random cluster sampling with a sample size of 129 high school students, 68 students in rural areas and 61 students in urban areas. The results showed significant differences in the material awareness of consumer rights variables and the three attitude dimensions. On the contrary, there was no difference in material awareness of consumer obligations, objective knowledge of rights and obligations and significant smart consumer behaviour on smart consumer behaviour in both regions. Students' age, objective knowledge about consumer obligations, and attitudes (affective and conative dimensions) significantly positively affect smart consumer behaviour in high school students.

Published: May 2022

This paper presents a fully analytical model for the current-voltage (I–V) characteristics of Resonant Tunneling Diodes. Based on Tsu-Esaki formalism, we consider the full electrical potential distribution in the structure, including the space charge regions at the emitter and collector layers. In addition, we account for the scattering suffered by carriers when tunneling through the double-barrier region, as a function of the applied bias voltage. These considerations improve the accuracy of the proposed model when compared with other approaches while keeping it physics based and fully analytical. Finally, the model is validated with experimental and numericaldata, demonstrating its feasibility for applications in circuit simulation environments.
A General gm/Id Temperature-Aware Design Methodology Using 180 nm CMOS up to 250 °C
Authors: Raposo de Oliveira Martins Joao Roberto , De Oliveira Alves Francisco , Maris Ferreira Pietro
Published: May 2022

The advent of the Internet-of-Things brings new challenges in circuit design. The presence of circuits and sensors in harsh environments brought the need for methodologies that account for them. Since the beginning of the transistors, the temperature is known for having a significant impact on performance, and even though very low temperature sensitivity circuits have been proposed, no general methodology for designing them exists. This paper proposes a general gm over Id technique for designing temperature-aware circuits that can be used either on measurement data, analytically, or based on simulation models. This model is validated using measurements up to 250°C of X-FAB XT018 transistors and later with a circuit design example.
