Accelerated variance-reduced methods for saddle-point problems
EURO Journal on Computational Optimization, 2022 We consider composite minimax optimization problems where the goal is to find a saddle-point of a large sum of non-bilinear objective functions augmented by simple composite regularizers for the primal and dual variables.

Angewandte Chemie International Edition, Accepted Article.We investigate two unusual phenomena in self‐assembly of anisotropic molecules from isotropic (Iso) melt: a heat‐capacity (Cp) maximum, and spontaneous formation of the recently discovered chiral liquid (Iso*). Based on experiments on new non‐chiral monomers, dimers and polymers, we construct a statistical theory that shows why many complex ...

The role of convexity on saddle-point dynamics: Lyapunov function and robustness [PDF]
arXiv, 2016 This paper studies the projected saddle-point dynamics associated to a convex-concave function, which we term saddle function. The dynamics consists of gradient descent of the saddle function in variables corresponding to convexity and (projected) gradient ascent in variables corresponding to concavity.

Dynamical Behaviour of a Time Delay Model of the ERK and STAT5 Interaction [PDF]
Bioautomation, 2007 In this paper we have done sensitive analysis of a time delay model which describes the ERK and STAT5 interaction. The results show that the type of the equilibrium point of the model can be a compound saddle-focus or a compound saddle-knot.

The Anatomical Record, EarlyView.Abstract The three mammalian auditory ossicles enhance sound transmission from the tympanic membrane to the inner ear. The anterior anchoring of the malleus is one of the key characters for functional classification of the auditory ossicles. Previous studies revealed a medial outgrowth of the mallear anterior process, the processus internus ...

Chemistry – An Asian Journal, EarlyView.Tetrathiafulvalenes (TTFs) extended by polycyclic aromatic hydrocarbons (PAHs) constitute a class of redox‐active chromophores. This review summarizes PAH‐extended TTFs for which the PAH core features five‐membered rings together with six‐, seven‐, and/or eight‐membered rings.

Inflation and reheating predictions in polynomial inflation with small and large fields
Physics Letters BWe explore the inflationary dynamics and reheating predictions of the fourth-order generalized polynomial inflation model featuring adjustable saddle-point position and flatness near the saddle point for both small and large field cases, based on the ...

BioEssays, EarlyView.Cell shape changes underlie animal development, physiology, and disease. The cell surface is mechanosensitive to the microenvironment and cytoskeleton activities, which generate plasma membrane topographies recognized and affected by Arp2/3 actin network induction pathways to remodel cell shape during immune cell migration, neural progenitor cell ...
