Biolipid Film‐Fused Electrochemiluminescence for Multipurpose In Situ Bioassays

Advanced Science, EarlyView.
An ECL‐emissive, membrane‐interactive scaffold was fabricated, and facilely fused with natural and non‐native phospholipids into multifactorial mimicries of cytomembranes and vesicles for in vitro representative membrane‐process probing. Such a biointerface‐based, state‐sensitive ECL paradigm not only pinpointed proximal phenomena, including channeling

Physics‐Based Compact Modeling of Advanced 3D Nanoscale Vertical NAND Flash Memory

Advanced Electronic Materials, EarlyView.
For advanced 3D NAND flash memory, a unified compact model for SPICE is proposed that spans from the intrinsic unit cell to the full string and captures the electrostatic coupling with adjacent inhibit strings. It can successfully predict read behavior, program/erase dynamics, and interactions between neighboring cells, reflecting array‐level behavior ...

A Bramble-Pasciak conjugate gradient method for discrete Stokes equations with random viscosity

, 2018
We study the iterative solution of linear systems of equations arising from stochastic Galerkin finite element discretizations of saddle point problems. We focus on the Stokes model with random data parametrized by uniformly distributed random variables ...

Comparing the Latent Features of Universal Machine‐Learning Interatomic Potentials

Advanced Intelligent Systems, EarlyView.
This study quantitatively assesses how universal machine‐learning interatomic potentials encode the chemical space into latent features, showing unique model‐specific representations with high cross‐model reconstruction errors. It explores how training datasets, protocols, and targets affect these encodings.

Combined Preconditioning with Applications in Reservoir Simulation

, 2013
We develop a simple algorithmic framework to solve large-scale symmetric positive definite linear systems. At its core, the framework relies on two components: (1) a norm-convergent iterative method (i.e. smoother) and (2) a preconditioner. The resulting

Iterative solutions to the steady state density matrix for optomechanical systems [PDF]

, 2014
We present a sparse matrix permutation from graph theory that gives stable incomplete Lower-Upper (LU) preconditioners necessary for iterative solutions to the steady state density matrix for quantum optomechanical systems.

Udzawa-type iterative method with parareal preconditioner for a parabolic optimal control problem

IOP Conference Series: Materials Science and Engineering, 2016
© Published under licence by IOP Publishing Ltd.The article deals with the optimal control problem with the parabolic equation as state problem. There are point-wise constraints on the state and control functions. The objective functional involves the observation given in the domain at each moment. The conditions for convergence Udzawa's type iterative

From cramming to binge‐watching: Integrating documentary‐based assessment into a pharmacology and toxicology curriculum—a qualitative study

British Journal of Clinical Pharmacology, EarlyView.
Abstract Aims In the context of pharmacology and toxicology education, there is a growing shift toward programmatic assessment models that prioritize longitudinal learning, reflection and development of higher‐order cognitive skills. As part of this transition, we are exploring alternative and more meaningful forms of assessment. This qualitative study

Stakeholder Engagement as a Design Principle: Orchestrating a Digital Platform for the Safety and Sustainability of the Nanomaterials Sector

Business Strategy and the Environment, EarlyView.
ABSTRACT The governance of chemicals and nanomaterials presents a critical challenge, as significant uncertainties regarding safety and sustainability match their innovation potential. This creates a “knowledge‐to‐action” gap, hindering the practical implementation of safety and sustainability by design (SSbD) principles.
