The effective neutron multiplication factor (keff) of a fissile system is a function of space and time f(x, y, z, t), where (x, y, z) are the coordinates of the reference point in space, and t is time. The evidence of the time-dependence of the neutron multiplication factor of a fissile system was published in 2017. The spatial dependence is as important as the time dependence, as interacting arrays of fissile material during storage can lead to an increase in the system (keff). Therefore, evaluation of how the sto [...]

This study aimed to evaluate the psychometric properties of the Family Inclusion Scale (FIS) for administration to adults and older Mexican adults. To this end, a questionnaire was structured with scales to evaluate family inclusion, loneliness, and perceived stress; the last two scales were previously validated. The sample (n = 347) consisted of young university adults aged 20 to 24 years and their grandparents aged 60 years. The conceptual emphasis of the Family Inclusion Scale generated was the identification of [...]

A relevant objective of managing an electromagnetic (EM) device is to improve its expected results and reduce its undesirable side effects. In this context, this paper aims to evaluate the interest of the two One Health and Responsible Attitude methods in the daily practice of wireless transmission (or transfer) in EM energy devices. These approaches are respectively linked to device eco-design and optimization, as well as to the protection of biodiversity and ecosystems against device side effects related to EM fi [...]

Complementary and integrative medicine (CIM) is commonly used by cancer survivors; however, patterns of use among individuals engaged in structured exercise rehabilitation remain understudied. This cross-sectional survey examined CIM use among 157 cancer survivors enrolled in a structured exercise-based rehabilitation program. CIM modality use (dependent variable) was grouped into herbal supplements, mind-body practices, and manipulative and body-based categories and analyzed with demographic and clinical character [...]

Chronic cancer pain results from the complex interaction of nociceptive, neuropathic, and neuroimmune mechanisms, which vary according to tumor type, location, stage, and treatment history. Recent advances in cancer neuroscience have reframed pain as a dynamic manifestation of reciprocal tumor–nerve–immune interactions, rather than a mere consequence of tissue damage. In this model, malignant, stromal, and immune cells remodel nociceptive circuits at peripheral and central levels. This narrative review, conducted i [...]

Rothmund-Thomson syndrome (RTS) is a rare autosomal recessive disorder characterized by early-onset poikiloderma and multisystem abnormalities. Diagnosis is often confirmed through genetic testing, but in many resource-limited settings, molecular studies are unavailable, necessitating reliance on clinical and histopathological evaluation. We report a 1-year-old boy referred for assessment of progressive pigmented skin lesions. The patient was referred by a pediatrician with febrile neutropenia, bicytopenia suspicio [...]

Taiwan relies heavily on imported fossil fuels, with over 98% of its energy demand supplied by foreign sources, posing significant challenges to national energy security. To explore alternatives, this study investigates the potential of marine renewable energy by developing a 20 kW floating hydrokinetic turbine prototype designed for deployment in the Kuroshio Current. The research encompasses system design, model validation, and both tank and at-sea testing to evaluate hydrodynamic performance and power generation [...]

Acupuncture has become an increasingly relevant complementary modality in modern gynecology and assisted reproduction. Its uses include the management of menstrual disorders, menopausal symptoms, infertility, polycystic ovary syndrome (PCOS), endometriosis, and others. Scientific progress in neurophysiology, laser acupuncture, and biomedical imaging has enabled a deeper understanding of the central and peripheral mechanisms underlying acupuncture’s effects. This editorial summarizes current evidence regarding physi [...]

Enteropathogenic strains of Escherichia coli, like the serotype O157:H7, can cause significant health issues if consumed. Milk and dairy products can serve as a reservoir for the bacteria. Dissemination of multidrug-resistant E. coli through dairy products can become a potential health hazard if consumed. The present study investigates the occurrence of multidrug-resistant E. coli O157:H7 in raw milk obtained from farms and markets around Dhaka, Bangladesh. A Total of 50 milk samples were collected in this study fr [...]

Schizophrenia is a multifactorial mental disorder associated with multiple SNPs in the human genome, located mainly outside the annotated protein-coding genes. These regions contain a large number of retroelements, which drive epigenetic regulation. Therefore, it is suggested that schizophrenia-associated SNPs exert their influence on the pathological functioning and activation of retroelements, which contribute to epigenetic imbalance in the brain with the development of pathological processes. A reflection of the [...]
