This article deals with new concepts in a product MV-algebra, namely, with the concepts of Rényi entropy and Rényi divergence. We define the Rényi entropy of order of a partition in a product MV-algebra and its conditional version and we study their properties. It is shown that the proposed concepts are consistent, in the case of the limit of going to 1, with the Shannon entropy of partitions in a product MV-algebra defined and studied by Petrovičová ( , , 41-44). Moreover, we introduce and study the notion of Rényi divergence in a product MV-algebra. It is proven that the Kullback-Leibler divergence of states on a given product MV-algebra introduced by Markechová and Riečan in ( , , 267) can be obtained as the limit of their Rényi divergence. In addition, the relationship between the Rényi entropy and the Rényi divergence as well as the relationship between the Rényi divergence and Kullback-Leibler divergence in a product MV-algebra are examined.

Gender-based violence (GBV) refers to a specific form of interpersonal violence that is rooted in gender inequities and unequal distribution of power. GBV is defined as any type of violence, including physical, sexual, psychological, and economic, perpetrated against individual(s) based on actual or perceived gender, gender identity, gender expression, sex or sex characteristics, sexual orientation, or divergence from social norms on masculinity and femininity. Cisgender (cis) and transgender (trans) women and girls of all ages, including adolescents and young adults (AYAs) of ages 10-24 years, disproportionately experience GBV.

Abnormal tau phosphorylation is a key mechanism in neurodegenerative diseases. Evidence implicates infectious agents, such as Herpes Simplex Virus 1 (HSV-1), as co-factors in the onset or the progression of neurodegenerative diseases, including Alzheimer's disease. This has led to divergence in the field regarding the contribution of viruses in the etiology of neurodegenerative diseases.

Lagerstroemia excelsa is a unique plant species from China, holds a significant aesthetic and economic value, and plays a crucial role in landscape architecture and horticulture. Thus far, there is little genetic and genomic information available about this species, which limits its use in development of new cultivars. In this study, a high-quality genome map of L.

Background And Objectives: Low-birth weight, premature infants often have severe intraventricular hemorrhage (IVH), which can result in posthemorrhagic hydrocephalus (PHH), sometimes requiring cerebrospinal fluid diversion. Initial temporizing management of PHH includes placement of a ventriculosubgaleal shunt (VSGS) or ventricular access device (VAD). Studies have found similar permanent shunt conversion rates between VSGS and VAD but were limited by sample scope and size.

Plant growth-promoting rhizobacterium Sp7 utilizes fructose efficiently via a fructose phosphotransferase system (Fru-PTS). Its genome encodes two putative Fru-PTS, each consisting of FruB (EIIA), FruK (Pfk), and FruA (EIIBC) proteins. We compared the proteomes of Sp7 grown with malate or fructose as sole carbon source, and noticed upregulation of the constituent proteins of Fru-PTS1 only on fructose.
