The work focused on modelling and optimisation of integrated renewable energy conversion technologies based on sunlight, wind, and biomass, with dual energy storage (battery and hydrogen), for Patani Island, Delta State, Nigeria. The study was aimed at satisfying the energy demand of the Patani Island community (5°13’43” N, 6°11’29” E). A mathematical model was developed to describe the integrated system, and a genetic algorithm was employed to optimize the allocation of energy demand, energy generation, and energy [...]

Schizophrenia spectrum disorders (SSDs) are complex conditions with chronic symptoms and impairments associated with greater risk for physical comorbidity and early mortality. Understanding end-of-life care in older adults with SSDs is crucial for improving geriatric psychiatric care and identifying healthcare disparities. A cohort of 254 older adult decedents with a history of schizophrenia or schizoaffective disorder was identified using the Rochester Epidemiology Project. A control group of 254 older adult deced [...]

The design of products in Neuromarketing using machine learning methods has been a continuous challenge in Computer-aided design. Previously, deep learning techniques have been applied to generate random images for domains such as furniture, fashion, and product design. However, using deep generative methods requires a large amount of data and overlooks human aspects in the design process. This paper aims to extract human perceptual factors from brain signals using a Transformer-based model and involve them in arti [...]

Male infertility is a growing concern worldwide, with almost half of infertility cases being male, and the trend is rising in China as a result of multifaceted genetics-environment interaction. Important breakthroughs have been made in identifying mutations in annotated protein-coding genes associated with male infertility. However, a significant part of the human genome, namely non-coding DNA, has not yet been explored. Recent breakthroughs in the realm of high-throughput genomic technologies have unveiled the ind [...]

The "Sama Code" is a protocol implemented in Iranian pre-hospital emergency services to manage time and treat patients with suspected stroke symptoms based on the FAST criteria. This study aims to analyze the workflow of patients with stroke symptoms transferred under the Sama Code. All patients with neurological symptoms who were brought to Imam Reza Hospital by pre-hospital emergency services after activating the Sama Code during the years 2021 and 2022 were included in the study. Data were collected from pre-hos [...]

Non-invasive prenatal testing (NIPT) is now standard in prenatal care in many countries, even though it was introduced only about 15 years ago. Due to its rapid adoption into decades-old prenatal care plans, gynecologists, obstetricians, and the general public still struggle to understand the possibilities, benefits, and limitations of NIPT. The biggest challenge facing NIPT is that comprehensive training for healthcare professionals and independent, unbiased information for pregnant women and their families about [...]

Although methods of ethnic-racial socialization have been studied in the past, welcoming in a new digital age has affected how parents engage with their children on topics such as race and culture. While media can be an engaging way to expose young children to race and culture, the underrepresentation of Black youth in media in the United States has posed a dilemma for Black parents about the best way of using media to socialize their young children. To understand how Black mothers expose their children to ideas ab [...]

This work addresses the application of a method to examine the spatial extent of ecological resources and green space on small Department of Energy (DOE) sites and comparison to ecological resources and green space in the surrounding region. Increasingly, governmental regulators, resource trustees, and the public are concerned that federal facilities are protecting human health and the environment, including ecological resources on their sites. This paper uses the National Land Cover/Land Use Database to examine an [...]

Electrical submersible pumps (ESPs) are an efficient and reliable artificial lift method for lifting large volumes of fluids from wellbores at flexible rates. Despite their advantages, including high flow rates and real-time downhole telemetry, ESPs are prone to frequent and unforeseen failures under harsh reservoir conditions, resulting in costly production delays and interventions. This paper presents an integrated evaluation of ESP failure mechanisms based on an analysis of run and pull reports, dismantle inspec [...]

Salinity poses a danger to food security; hence, it is necessary to create crop types that can withstand salt to meet the growing demand for food. The goal of the current study was to examine the morphological and biochemical responses of wheat (Triticum aestivum L.) genotypes under salt stress. Salt tolerance in ten wheat cultivars and five selected F1 hybrids was assessed at the germination and seedling stage. Genotypes were assessed for seven traits under control (0 mM NaCl) and salinity stress (150, 200, and 25 [...]
