ABSTRACT Background Chronic kidney disease is a growing public health problem worldwide, and the number of patients requiring renal replacement therapy is steadily increasing. Türkiye has experienced a similar rise in both the incidence and prevalence of renal replacement therapy over the past decades; however, national‐level projections of future ...

Explicit forms of the trace formula for GL(2)
There has recently been renewed interest in the trace formula–in particular, that of the initial case of GL(2)–due to counting applications in the function field case. For these applications, one needs a very precise form of the trace formula, with all terms computed explicitly.

Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM
Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.

Thermodynamics of two black holes
We study a system of two charged non-rotating black holes separated by a strut. Using the exact solution of the Einstein-Maxwell equations, which describes this system, we construct a consistent form of the first law of thermodynamics.

Mapping the evolution of mitochondrial complex I through structural variation
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Explicit Jordan form for certain block triangular matrices
Let \(J_r\) denote the \(r\times r\) nilpotent Jordan block. Let \(M\) be the block upper triangular matrix \(\begin{pmatrix} A & X\\ 0 & B\end{pmatrix}\) where \(A\) and \(B\) are given square matrices. The ``Carlson problem'' is to find all the possible Jordan forms of the matrix \(M\).

Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

Numerical Analysis of Structures of Revolution using Universal Matrices Approach
Stress and displacement analysis of structures of revolution under axisymmetric loading is of considerable interest in engineering. Many practical problems can be idealized as an axisymmetric case, which simplifies the analysis and reduces the ...
