In this work, a GaN-based gamma-voltaic device is modeled and optimized using a coupled radiation–device simulation framework. Monte Carlo simulations are employed to model gamma energy deposition and radiation-induced lattice displacement within GaN, while TCAD simulations are used to analyze the resulting electric field distributions, charge transport, and current collection in multiple device architectures. Simulation results identify single-cell configurations capable of producing up to 39 μA/cm² of current with an open-circuit voltage of 2.62 V, and stacked-cell architectures capable of producing up to 200 μA/cm². The results highlight the importance of heavy, asymmetric doping, a moderately sized depletion region, and P⁺–p–n–N⁺ junction designs in maximizing charge collection efficiency. In addition, the impact of trap states and radiation-induced defects on device performance is examined, providing insight into degradation mechanisms in irradiated GaN gamma-voltaic devices.

With the global spread of the “Kidulting” trend—where adults seek childhood-like comfort to alleviate life pressure—and the rise of emotional consumption, plush toys have shifted from children’s items to adult emotional companions. This paper uses the case study analysis method, outlining how jELLYCAT, a UK’s high-end plush brand, aligns with Kidulting psychology to drive success. jELLYCAT’s brand background includes its positioning shift to “all age groups” and strengths in design, quality, and sustainability. This study discusses the underlying reasons for the brand’s success. The brand’s success drivers include capturing adult emotional needs (childlike and compensation psychology), scenario-based/limited-edition products, in-store “healing” services, and multi-channel marketing. In addition, this study identifies challenges like high prices, counterfeits, and competition, and proposes solutions (AR/VR experiences, customizable accessories). The study concludes that jELLYCAT’s core strength lies in transforming products into “emotional partners”, offering a model for brands leveraging Kidulting trends in the emotional economy.

Multilingual households are rapidly expanding worldwide, yet most research still focuses on monolingual or bilingual families, leaving the dynamics of multilingual households underexplored. Guided by Coleman’s Family Capital Theory, this study investigates how multi-ethnic families in Canada, Pakistan, Jordan, and Saudi Arabia negotiate heritage language transmission alongside English acquisition. Using a cross-country ethnographic design, participant observation, semi-structured interviews, video reminiscences, and archival research were conducted with 40 families (Canada 12, Pakistan 10, Jordan 9, Saudi Arabia 9), including children aged 5–18. Sample sizes were tailored to cultural access and feasibility rather than equal national quotas. Findings reveal that storytelling, moral teaching, and religious rituals are central to preserving heritage languages, while English is prioritized for education and employment. Families experienced accent-related identity issues, reduced heritage language proficiency among younger members, and intergenerational communication gaps. Children’s incidental exposure to digital platforms (e.g., educational apps, YouTube, online religious classes) and the challenges of displacement among migrant families were observed but not systematically measured. The study underscores that English supports integration and mobility but risks weakening cultural and linguistic identity. It recommends that educators and policymakers design pluralist, culturally responsive strategies—such as embedding family-driven literacy practices into curricula and fostering additive bilingualism through community and school partnerships—to sustain heritage languages alongside English. The comparative ethnographic approach offers a replicable framework for future cross-cultural studies. Longitudinal research and systematic examination of digital technologies and displacement contexts are proposed as key directions to advance understanding of intergenerational language maintenance and identity resilience.

Bacillus anthracis is widespread in soil and a causative agent of anthrax, primarily in herbivores. Here, we report the draft genome sequence of Bacillus anthracis strain N1, which was isolated from a recreational freshwater lake and found to carry multiple antibiotic resistance genes and biosynthetic gene clusters.

Children who do not receive any routine vaccinations (ie, who have 0-dose status) are at elevated risk of death, morbidity, and socioeconomic vulnerabilities that limit their development over the life course. India has the world's highest number of children with 0-dose status; analysis of national and subnational patterns is the first important step to addressing this problem. To examine the patterns among children with 0-dose immunization status across all 36 states and union territories (UTs) in India over 29 years, from 1993 to 2021, and to elucidate the relative share of multiple geographic regions in the total geographic variation in 0-dose immunization. This repeated cross-sectional study analyzed all 5 rounds of India's National Family Health Survey (1992-1993, 1998-1999, 2005-2006, 2015-2016, and 2019-2021) to compare the prevalence of children with 0-dose status across time-space and geographic regions. The Integrated Public Use of Microdata Series was used to construct comparable geographic boundaries for states and UTs across surveys. The study included a total of 125 619 live children aged 12 to 23 months who were born to participating women. The outcome was a binary indicator of children's 0-dose vaccination status, coded as children aged 12 to 23 months at the time of the survey who had not received the first dose of the diphtheria-tetanus-pertussis-containing vaccine. The significance of each geographic unit was computed using the variance partition coefficient (VPC). Among 125 619 children, the national prevalence of those with 0-dose status in India decreased from 33.4% (95% CI, 32.5%-34.2%) in 1993 to 6.6% (95% CI, 6.4%-6.8%) in 2021. A substantial reduction in the IQR of 0-dose prevalence across states from 30.1% in 1993 to 3.1% in 2021 suggested a convergence in state disparities. The prevalence in the northeastern states of Meghalaya (17.0%), Nagaland (16.1%), Mizoram (14.3%), and Arunachal Pradesh (12.6%) remained relatively high in 2021. Prevalence increased between 2016 and 2021 in 10 states, including several traditionally high-performing states and UTs, such as Telangana (1.16 percentage points) and Sikkim (0.92 percentage points). In 2021, 53.0% of children with 0-dose status resided in the populous states of Uttar Pradesh, Bihar, and Maharashtra. A multilevel analysis comparing the share of variation at the state, district, and cluster (primary sampling unit) levels revealed that clusters accounted for the highest share of the total variation in 2016 (44.7%; VPC [SE], 1.04 [0.32]) and 2021 (64.3%; VPC [SE], 0.38 [0.12]). In this cross-sectional study, findings from approximately 3 decades of analysis suggest the need for sustained efforts to target populous states like Uttar Pradesh and Bihar and northeastern parts of India. The resurgence of 0-dose prevalence in 10 states highlights the importance of programs like Intensified Mission Indradhanush 4.0, a major national initiative to improve immunization coverage. Prioritizing small administrative units will be important to strengthening India's efforts to bring every child into the immunization regime.

Tesla is an American electric car and energy company that makes and sells electric cars, solar panels, and energy storage equipment. We analyze how can Tesla buy and sell the machines in the most profitable way. Based on photovoltaic (PV) and net present value (NPV) rules, the infinite time optimal machine life model is established to analyze the investment projects of Tesla. Next, we calculate the optimal machine life effectively by using HJB equation. The PV and NPV rules and HJB equation are introduced in Related theoretical concepts included definitions, formulas, and applicable situations. We get the conclusion that the theoretical optimal machine exists which is using one machine only a year. But that is subject to market demand and supply. If we take all the factors into account, the calculation becomes complicated. So we just use the ideal case, and explain the meaning of optimal machine life for the company and related calculations in it.

A novel Coronavirus was identified in China as SARS-CoV-2 in December 2019 and was later declared a pandemic by the World Health Organization [1]. In most patients, COVID-19 presents with mild or moderate symptoms such as fever, cough, fatigue, and myalgia. However, around 10% of patients develop more severe symptoms such as pneumonia and multiorgan failure, which can result in death [1-2]. Until vaccines are widely available, the only way to reduce fatality rates is to treat affected patients with existing drugs and therapy options.
