Computational analysis of metagenomes requires the taxonomical assignment genome contigs assembled from DNA reads environmental samples. Because diverse nature microbiomes, length assemblies obtained can vary between a few hundred bp to Kbp. Current taxonomic classification algorithms provide accurate for long or short fragments organisms that have close relatives with annotated genomes. These are significant limitations metagenome because complexity microbiomes and paucity existing We...

Breast cancer is a prevalent form of across the globe, and if it not diagnosed at an early stage can be life-threatening. In order to aid in its diagnosis, detection, classification, computer-aided detection (CAD) systems are employed. You Only Look Once (YOLO)-based CAD algorithms have become very popular owing their highly accurate results for object tasks recent years. Therefore, most YOLO models implemented compare performance mass with various experiments on INbreast dataset. addition,...

INTRODUCTION: Personalized management strategies are pivotal in addressing irritable bowel syndrome (IBS). This multicenter randomized controlled trial focuses on comparing the efficacy of a microbiome-based artificial intelligence-assisted personalized diet (PD) with low-fermentable oligosaccharides, disaccharides, monosaccharides, and polyols (FODMAP) for IBS management. METHODS: One hundred twenty-one patients participated, 70 assigned to PD group 51 FODMAP group. subtypes, demographics,...

ABSTRACT Protein sequence design is a highly challenging task, aimed at discovering new proteins that are more functional and producible under laboratory conditions than their natural counterparts. Deep learning‐based approaches developed to address this problem have achieved significant success. However, these often do not adequately emphasize the properties of proteins. In study, we heuristic optimization method enhance key functionalities such as solubility, flexibility, stability, while...

Abstract Deep learning models have found extensive application in medical imaging analysis, particularly mammography classification. However, these encounter challenges associated with limited annotated public datasets. In recent years, self-supervised (SSL) has emerged as a noteworthy solution to addressing data scarcity by leveraging pretext and downstream tasks. Nevertheless, we recognize notable of designed for the classification task mammography. this context, propose novel model...
