Cutting plane methods for general integer programming [PDF]
Integer programming (IP) problems are difficult to solve due to the integer restrictions imposed on them. A technique for solving these problems is the cutting plane method.

In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

Quantile regression is a nondifferentiable convex optimization problem. We compare three classical numerical methods, two of them based on linear optimization, and the cutting plane method.

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

The Number of Plane Corner Cuts
An \(n\)-element subset \(\lambda\) of \(\mathbb{N}^2\) which is cut off a line is called a (plane) corner cut of size \(n\). Let be \({\mathbb{N}^2\choose n}_{ \text{cut}}\) the set of corner cuts of size \(n\). [See \textit{S. Onn} and \textit{B. Sturmfels}, ibid., 29-48 (1999; above).] The authors give a generating for the number \(\#{\mathbb{N}^2 ...
