A new form of three-body Faddeev equations in the continuum

We propose a novel approach to solve the three-nucleon (3N) Faddeev equation which avoids the complicated singularity pattern going with the moving logarithmic singularities of the standard approach. In this new approach the treatment of the 3N Faddeev equation becomes essentially as simple as the treatment of the two-body Lippmann-Schwinger equation. Very good agreement of the new and old approaches in the application to nucleon-deuteron elastic scattering and the breakup reaction is found.Comment: 20 pages, 3 eps figure

Characterising acute and chronic care needs: insights from the Global Burden of Disease Study 2019

Chronic care manages long-term, progressive conditions, while acute care addresses short-term conditions. Chronic conditions increasingly strain health systems, which are often unprepared for these demands. This study examines the burden of conditions requiring acute versus chronic care, including sequelae. Conditions and sequelae from the Global Burden of Diseases Study 2019 were classified into acute or chronic care categories. Data were analysed by age, sex, and socio-demographic index, presenting total numbers and contributions to burden metrics such as Disability-Adjusted Life Years (DALYs), Years Lived with Disability (YLD), and Years of Life Lost (YLL). Approximately 68% of DALYs were attributed to chronic care, while 27% were due to acute care. Chronic care needs increased with age, representing 86% of YLDs and 71% of YLLs, and accounting for 93% of YLDs from sequelae. These findings highlight that chronic care needs far exceed acute care needs globally, necessitating health systems to adapt accordingly

Solving the maximum agreement subtree and the maximum compatible tree problems on many bounded degree trees

Given a set of leaf-labeled trees with identical leaf sets, the well-known Maximum Agreement SubTree problem (MAST) consists of finding a subtree homeomorphically included in all input trees and with the largest number of leaves. Its variant called Maximum Compatible Tree (MCT) is less stringent, as it allows the input trees to be refined. Both problems are of particular interest in computational biology, where trees encountered have often small degrees. In this paper, we study the parameterized complexity of MAST and MCT with respect to the maximum degree, denoted by D, of the input trees. Although MAST is polynomial for bounded D [1, 6, 3], we show that the problem is W[1]-hard with respect to parameter D. Moreover, relying on recent advances in parameterized complexity we obtain a tight lower bound: while MAST can be solved in O(N O(D)) time where N denotes the input length, we show that an O(N o(D) ) bound is not achievable, unless SNP ⊆ SE. We also show that MCT is W[1]-hard with respect to D, and that MCT cannot be solved in O(N o(2D/2)) time, unless SNP ⊆ SE.

Review - Sporeforming probiotic bacteria: Characteristics, health benefits, and technological aspects for their applications in foods and beverages

Higher resistance of microbial spores to high temperatures, low pH and high pressures coupled with characteristics such as good stability and rapid germination make their use extremely desirable for the innovative formulation of several probiotic foods, mainly due to the inherent technological limitations of lactic acid bacteria (LAB), which represent the main probiotic microorganisms applied in food. Probiotic spores are resistant to several processing conditions employed in the food industry, thus presenting high feasibility of application and guaranteeing the functionality of probiotic foods; in addition, they are able to maintain such characteristics throughout the shelf life of such products stored at room temperature or under refrigeration.Scope and approachThis study presents a review of the main characteristics, technological implications, and types of consumption and health benefits of potential probiotic Bacillus spores.Key findings and conclusionsSpore-forming probiotics are available in different pharmaceutical forms (sachets, capsules, tablets, pills, liquid suspensions) and used in medical and veterinary fields, and more recently in the food industry. Health benefits of spore-forming probiotics should be intensively studied, evaluating their behavior in the GIT and other anatomical sites, determining the mechanisms of action involved and correlating them with the main beneficial effects on health. Spore-forming probiotics have great potential for applications in the food industry, since they present high resistance to the technological processes and physiological mechanisms of the body, which would be lethal to LAB.Fil: Soares, Mariana B..
