Wannier Function Perturbation Theory: Localized Representation and Interpolation of Wave Function Perturbation

open access: yes, 2021
Thanks to the nearsightedness principle, the low-energy electronic structure of solids can be represented by localized states such as the Wannier functions.

Pharmacological inhibition of the PERK pathway modulates hepatocellular carcinoma growth and immune signaling

open access: yesFEBS Open Bio, EarlyView.
Pharmacological inhibition of PERK in a DEN‐induced mouse model of liver cancer does not reduce tumor burden but alters cellular stress signaling. Despite blocking PERK activity, downstream stress responses, including CHOP expression, remain active, suggesting compensatory mechanisms within the unfolded protein response that may influence tumor ...

The Fréchet Derivative of an Analytic Function of a Bounded Operator with Some Applications

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2009
The main result in this paper is the determination of the Fréchet derivative of an analytic function of a bounded operator, tangentially to the space of all bounded operators. Some applied problems from statistics and numerical analysis are included as a

SINGULAR PERTURBATION APPROACH TO MAXIMUM PRINCIPLE FORMULATION OF VISCOUS INCOMPRESSIBLE FLUID FLOW

open access: yes, 2010
A method for the solution of viscous incompressible flow based on the Pontryagin's maximum principle is presented. By minimizing the cost function that ensures the continuity condition, an explicit control law for the pressure is derived with the help ...

The C‐terminal region of KIF26B is indispensable for nephron progenitor condensation and kidney formation in mice

open access: yesFEBS Open Bio, EarlyView.
KIF26B plays an important role in kidney development. We engineered mice lacking the C‐terminal region of KIF26B and found severe kidney defects, including bilateral renal agenesis, similar to full Kif26b knockout mice. The mutation disrupted nephron progenitor condensation and reduced Gdnf‐Wnt11 signaling, showing that the KIF26B C‐terminal region is ...

Stability of traveling wavefronts for a three-component Lotka-Volterra competition system on a lattice

open access: yesElectronic Journal of Differential Equations, 2018
This article concerns the stability of traveling wavefronts for a three-component Lotka-Volterra competition system on a lattice. By means of the weighted energy method and the comparison principle, it is proved that the traveling wavefronts with ...

On the Generation of Large Passive Macromodels for Complex Interconnect Structures

open access: yes, 2006
This paper addresses some issues related to the passivity of interconnect macromodels computed from measured or simulated port responses. The generation of such macromodels is usually performed via suitable least squares fitting algorithms.

Directed evolution of enzymes at the crossroads of tradition and innovation

open access: yesFEBS Open Bio, EarlyView.
An iterative cycle of data‐driven enzyme optimization comprising four stages: genetic diversification of a template enzyme, expression of protein variants, high‐throughput evaluation, and machine‐learning‐guided redesign of the next variant library.

Local infrared safety in time-ordered perturbation theory

open access: yesJournal of High Energy Physics
We develop a general expression for weighted cross sections in leptonic annihilation to hadrons based on time-ordered perturbation theory (TOPT). The analytic behavior of the resulting integrals over spatial momenta can be analyzed in the language of ...
