A survey of methods of feasible directions for the solution of optimal control problems [PDF]

open access: yes, 1972
Three methods of feasible directions for optimal control are reviewed. These methods are an extension of the Frank-Wolfe method, a dual method devised by Pironneau and Polack, and a Zontendijk method. The categories of continuous optimal control problems

Introduction to Reconfiguration

open access: yesAlgorithms, 2018
Reconfiguration is concerned with relationships among solutions to a problem instance, where the reconfiguration of one solution to another is a sequence of steps such that each step produces an intermediate feasible solution.

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

open access: yesFEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

The human gut microbiome across the life course

open access: yesFEBS Letters, EarlyView.
Despite significant individual variation and continuous change throughout life, the human gut microbiome follows some life stage‐specific trends. This article provides a brief overview of how gut microbiome composition shifts across different phases of life. Created in BioRender. Özkurt, E. (2026) https://BioRender.com/8q4nrnc.

Modulation of Homer1 EVH1 domain internal dynamics by putative autism‐associated mutations

open access: yesFEBS Letters, EarlyView.
The putative autism‐associated M65I and S97L variants of the EVH1 domain of the postsynaptic scaffold protein Homer1 do not exhibit substantial changes in their overall structure or partner binding. Both of them, but especially the M65I variant, show altered internal dynamics relative to the wild‐type domain on the μs‐ms timescale, indicated by the ...

Finding Feasible Mold Parting Directions Using Graphics Hardware [PDF]

open access: yes, 2008
We present new programmable graphics hardware accelerated algorithms to test the castability of geometric parts and assist with part redesign. These algorithms efficiently identify and graphically display undercuts and minimum and insufficient draft ...

Explaining Risk Regulation Regimes:Exploring the “Minimal Feasible Response” Hypothesis [PDF]

open access: yes, 1999
This paper provides an analytic description of four health-related risk regulation regimes in the UK (governing radon in the home, dangerous dogs outside the home, pesticide residues in food and water, and ambient benzene).

Research progress on the pathogenesis, prevention and treatment of immune platelet transfusion refractoriness

open access: yesZhongguo shuxue zazhi
Platelet transfusion refractoriness (PTR) is one of the common problems in platelet transfusion, significantly impacting patient clinical outcomes and increasing the demand for allogeneic platelet transfusion.

From mice to humans—divergent strategies for intestinal homeostasis and regeneration

open access: yesFEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

A path-following feasible interior-point algorithm for mixed symmetric cone linear complementarity problems [PDF]

open access: yes, 2020
In this paper, we propose a feasible interior-point algorithm for mixed symmetric cone linear complementarity problems which are a general class of complementarity problems.
