Effects of Bacillus coagulans and the biomass of Spirulina platensis on quality characteristics and probiotic viability of gluten free cupcakes

In this study, gluten-free corn flour cupcakes were formulated with different levels of Spirulina platensis (0, 1, 2, and 3%) and the probiotic bacterium Bacillus coagulans (0 and 1%), and their physicochemical, microbial, textural, and sensory properties and probiotic survival w...

Safe and adaptive control of non-stationary stochastic systems via Lyapunov-constrained distributional reinforcement learning

Abstract Non-stationary environments pose significant challenges for reinforcement learning (RL), particularly in safety-critical applications like robotics and energy systems, where adaptability, stability, and robustness to uncertainty are essential. This paper introduces Lyapu...

A hybrid approach based on deep learning to improve segmentation, classification and localization of different types of brain tumors in MRI images

Brain tumors pose significant health risks, and early detection is critical for improving patient outcomes. Although Magnetic Resonance Imaging (MRI) is widely used for diagnosis, accurate interpretation remains challenging, particularly in resource-limited clinical settings. To...

Machine learning-based prediction of subjective cognitive impairment levels in cancer survivors using demographic predictors

Objectives Cancer-related cognitive impairment is a decline in cognitive functioning following cancer treatment that negatively affects survivors’ quality of life. Self-report tools such as the Cognitive Failure Questionnaire (CFQ) offer a rapid and cost-effective method for earl...

Concurrent infection with Clostridium chauvoei, Clostridium septicum and Clostridium perfringens type A in cattle: a case report

Blackleg, caused by Clostridium chauvoei , is an acute, fatal infectious disease characterized by necrotizing myositis and toxemia primarily affecting cattle and sheep. Gas gangrene (malignant edema), a similar necrotizing myositis, is caused by multiple anaerobes including C. ch...

Effect of a free sugar-restricted diet on anthropometric parameters, lipid profile, and glycemic control in women with polycystic ovary syndrome: a randomized controlled trial

Abstract Background High-sugar diets rich in fructose and other simple sugars are associated with increased lipogenesis and insulin resistance, potentially increasing the risk of metabolic syndrome, a condition closely linked with polycystic ovary syndrome (PCOS). This study aime...

CortexNet: convolutional neural networks for alzheimer’s disease diagnosis using brain MRI

Alzheimer’s disease is one of the most common degenerative brain diseases, and its early detection plays an important role in improving clinical management, increasing treatment effectiveness, and reducing the consequences of disease progression. In this study, a family of convol...
