A Variational Convergence that Yields Chattering Systems [PDF]

Annales de l'Institut Henri Poincaré C, Analyse non linéaire, 1989
Chattering variational problems are introduced and employed as limits of a variational convergence mode which is compact and preserves the optimal values. The phenomenon arises in systems with highly oscillatory coefficients. Robustness of, and approximations to, optimal controls in such cases are examined.

The role of standing variation in geographic convergent adaptation [PDF]

The American Naturalist, 2014
Abstract The extent to which populations experiencing shared selective pressures adapt through a shared genetic response is relevant to many questions in evolutionary biology. In a number of well studied traits and species, it appears that convergent evolution within species is common.

Unique circulating miRNAome signatures captured with distinct molecular states in Lynch syndrome and sporadic colorectal cancer

Molecular Oncology, EarlyView.
Circulating microRNA profiles distinguish nonmalignant Lynch syndrome from cancer‐associated Lynch syndrome, sporadic colorectal cancer, and healthy controls. Age‐stratified analysis reveals disease‐specific regulatory states, and a six‐miRNA panel shows concordant separation in an independent colorectal tissue cohort.

Approximation of an Inertial Iteration Method for a Set-Valued Quasi Variational Inequality

Iraqi Journal for Computer Science and Mathematics
In this article, a projection type two step inertial iterative scheme for investigating set-valued quasi variational inequality in real Banach spaces is designed. We manifest the existence result and verified by an illustrative example.

Existence of Solutions and Convergence of a Multistep Iterative Algorithm for a System of Variational Inclusions with (H,η)-Accretive Operators

Fixed Point Theory and Applications, 2007
We introduce and study a new system of variational inclusions with (H,η)-accretive operators, which contains variational inequalities, variational inclusions, systems of variational inequalities, and systems of variational inclusions in the ...

Adaptive variational discretization approximation method for parabolic optimal control problems

Journal of Inequalities and Applications, 2020
In this paper, we study variational discretization method for parabolic optimization problems. Firstly, we obtain some convergence and superconvergence analysis results of the approximation scheme.

GelMA‐based 3D spheroids recapitulate transcriptomic and functional hallmarks of myeloid sarcoma

FEBS Open Bio, EarlyView.
GelMA 5% hydrogels support the formation of myeloid leukemia spheroids that recapitulate MS‐specific features, including G1 arrest, apoptosis, and ECM‐driven transcriptomic reprogramming. The 3D model mimicked soft‐tissue‐like stiffness and oxygen conditions, and transcriptomic convergence with primary MS samples confirmed its utility as a preclinical ...
