Expected Residual Minimization Method for a Class of Stochastic Quasivariational Inequality Problems

open access: yesJournal of Applied Mathematics, 2012
We consider the expected residual minimization method for a class of stochastic quasivariational inequality problems (SQVIP). The regularized gap function for quasivariational inequality problem (QVIP) is in general not differentiable. We first show that

Differentiability of regularized gap functions for a kind of variational inclusions and local uniqueness of solutions [PDF]

open access: yesSCIENTIA SINICA Mathematica, 2020
Summary: In this paper, we mainly explore continuity and differentiability properties of regularized gap functions for a kind of nonconvex variational inclusions and its associated solution mapping by making use of the properties of the Moreau envelope functions of the prox-regular function and its proximal mapping.

Regularized LIML for many instruments [PDF]

open access: yes, 2015
The use of many moment conditions improves the asymptotic efficiency of the instrumental variables estimators. However, in finite samples, the inclusion of an excessive number of moments increases the bias.

On Penalty and Gap Function Methods for Bilevel Equilibrium Problems

open access: yesJournal of Applied Mathematics, 2011
We consider bilevel pseudomonotone equilibrium problems. We use a penalty function to convert a bilevel problem into one-level ones. We generalize a pseudo-∇-monotonicity concept from ∇-monotonicity and prove that under pseudo-∇-monotonicity property any

Optical conductivity, Drude weight and plasmons in twisted graphene bilayers

open access: yesNew Journal of Physics, 2013
We numerically calculate the optical conductivity of twisted graphene bilayers within the continuum model. To obtain the imaginary part, we employ the regularized Kramers–Kronig relation, allowing us to discuss arbitrary twist angles, chemical potential ...

Gap junctions, dendrites and resonances : a recipe for tuning network dynamics [PDF]

open access: yes, 2013
Gap junctions, also referred to as electrical synapses, are expressed along the entire central nervous system and are important in mediating various brain rhythms in both normal and pathological states.

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.
