Constrained Minimization Algorithms. Linear Models [PDF]
This book is a collection of 19 articles which reflect the courses given at the Collège de France/Summer school “Reconstruction d'images − Applications astrophysiques“ held in Nice and Fréjus, France, from June 18 to 22, 2012. The articles presented in this volume address emerging concepts and methods that are useful in the complex process of improving

A Linear Network Code Construction for General Integer Connections Based on the Constraint Satisfaction Problem [PDF]
The problem of finding network codes for general connections is inherently difficult in capacity constrained networks. Resource minimization for general connections with network coding is further complicated.

Existence of normalized solutions for the nonlinear Schrödinger–Poisson–Boltzmann system
In this paper, we consider the following nonlinear Schrödinger–Poisson–Boltzmann (SPB) system under an $L^2$-norm constraint \begin{equation*} \begin{cases} -\Delta u+\lambda u+\phi u=\left|u\right|^{p-2}u&\text{in}\ \mathbb{R}^3,\\ -\Delta \phi+\kappa ...

Proposed shunt rounding technique for large-scale security constrained loss minimization [PDF]
The official published version can be obtained from the link below - Copyright @ 2010 IEEE.Optimal reactive power flow applications often model large numbers of discrete shunt devices as continuous variables, which are rounded to their nearest discrete ...

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)

Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

Some remarks on duality and optimality of a class of constrained convex quadratic minimization problems [PDF]
In this paper the duality and optimality of a class of constrained convex quadratic optimization problems have been studied. Furthermore, the global optimality condition of a class of interval quadratic minimization problems has also been ...

The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

Cell geometry determines symmetric and asymmetric division plane selection in Arabidopsis early embryos. [PDF]
Plant tissue architecture and organ morphogenesis rely on the proper orientation of cell divisions. Previous attempts to predict division planes from cell geometry in plants mostly focused on 2D symmetric divisions.

String-Averaging Projected Subgradient Methods for Constrained Minimization [PDF]
We consider constrained minimization problems and propose to replace the projection onto the entire feasible region, required in the Projected Subgradient Method (PSM), by projections onto the individual sets whose intersection forms the entire feasible ...
