“Host defence peptides can complement the efficacy of conventional antibiotics amid the current strain resistance crisis. In addition to their microbicidal actions, they may have an immunomodulatory function, reinforcing an antimicrobial fight in a way that conventional antibiotics cannot efficiently address.”

“We argue in favor of a positive answer to this question, providing evidence from the context of Cuban university students, where study groups form spontaneously at all academic stages. Personal epistemology, measured with a beliefs questionnaire, shows interesting behaviors as function of the group parameters.”

“We briefly review the history and achievements of the Department of Theoretical Physics (DFT) of the ICIMAF since its foundation in 1976. The data and opinions of former and current members of the DFT were taken from a series of interviews made to the participants of the scientific conference FT-45, held virtually in March 2021, to celebrate the 45th anniversary of the DFT.”

“Functional Gastrointestinal Disorders (FGID) are a frequent motive for health care needs in gastroenterology, thus causing serious problems socially and in family dynamics. We study the clinical characteristics and natural history of the Irritable Bowel Syndrome (IBS) in children and adolescents attending our outpatients' practice of pediatric gastroenterology, according to the new Rome criteria. We found that IBS is relatively frequent as a cause for functional Chronic Abdominal Pain (CAP) and that an interrogatory following Rome criteria is useful for its diagnosis.”

“This work introduces a new neural network architecture that uses bidirectional associations-based pooling to extract high-level features and labels from multi-label data. Unlike the pooling approaches reported in the literature, our proposal does not require input data to have any topological properties as typically occurs with images and videos. The numerical results show that our bidirectional pooling helps reduce the number of problem features and labels while preserving the discriminatory power of the network.”

“We proposed definitions and theorems regarding Fuzzy Cognitive Maps (FCMs), which allow estimating bounds for the activation value of each neuron and analyzing the covering and proximity of feasible activation spaces. The main theoretical findings suggest that the state space of any FCM model equipped with transfer F-functions shrinks infinitely with no guarantee for the FCM to converge to a fixed point but to its limit state space. This result, in conjunction with the covering and proximity values of FCM-based models, helps to understand their poor performance when solving complex simulation problems.”
