Microfluidic Engineering of Microgels: A Review of Emerging Technologies, Materials, Fabrication Strategies, and Applications

Advanced Healthcare Materials, EarlyView.
Recent advances in microfluidic technologies for microgel fabrication are critically reviewed, highlighting the capabilities and limitations of major microfluidic platforms and discussing how platform design, material selection, and crosslinking strategies influence microgel architecture and functionality. Current challenges and future opportunities in

Basic Concepts, Identities and Inequalities - the Toolkit of Information Theory

Entropy, 2001
: Basic concepts and results of that part of Information Theory which is often referred to as "Shannon Theory" are discussed with focus mainly on the discrete case. The paper is expository with some new proofs and extensions of results and concepts.

Magnetoactive Hydrogels to Probe Curvature‐Directed Endothelial Cell Mechanosensing

Advanced Healthcare Materials, EarlyView.
This work establishes a platform to investigate local curvature as a regulator of endothelial mechanosensing independent of shear stress. Magnetoactive hydrogels enable on‐demand curvature of endothelial monolayers to reproduce tortuosity quantified by clinically established metrics.

Limits to the Hall Effect and Other Nonreciprocal Effects in Three‐Dimensional Metamaterials

Advanced Materials, EarlyView.
Comprehensive and fundamental bounds on nonreciprocal effects in three‐dimensional metamaterials are derived. They reveal that the effective Hall mobility cannot exceed the largest constituent mobility, that, under certain conditions, the Verdet constant cannot be enhanced, and that, for constituents with Hall coefficients of the same sign, the largest

g-Convex Weight Sequences

Mathematics, 2018
In this paper, we introduce the notion of g-convex weight sequence (gcws) for connected graphs based on the concept of g-convexity and g-weight. g-weight is a natural generalization of the notion of branch weight for trees.

Ferromagnetism of Molecular Beam Epitaxy‐grown Ultra‐thin Cr2Ge2Te6 Films Down to the Monolayer Limit on Si Substrates

Advanced Materials, EarlyView.
Uniform monolayer Cr2Ge2Te6 films are achieved on Si substrates by molecular beam epitaxy. Intrinsic ferromagnetism with perpendicular magnetic anisotropy is established in the films by anomalous Hall effect and superconducting quantum interference device measurements, albeit with strong magnetic fluctuations characteristic of its 2D nature.

Duality for nonsmooth mathematical programming problems with equilibrium constraints

Journal of Inequalities and Applications, 2016
In this paper, we consider the mathematical programs with equilibrium constraints (MPECs) in Banach space. The objective function and functions in the constraint part are assumed to be lower semicontinuous.

Current‐Induced Domain Wall Dynamics in Pt/Co/Ni/Co Nanoribbons With Curvilinear Cross‐Sections

Advanced Materials, EarlyView.
3D curvilinear magnetic racetrack nanoribbons are formed with concave and convex cross‐sections using an advanced multi‐photon 3D printer. The curvature is shown to strongly affect current‐induced domain wall motion along the nanoribbons. In nanoribbons with cross‐sections that have both concave and convex segments, the velocities of domain walls with ...

Robust controlled vector variational inequalities for multi-dimensional fractional control optimization problems [PDF]

Archives of Control Sciences
This paper is devoted to study robust efficiency in terms of variational inequality for a class of multi-dimensional multi-objective first-order PDE-constrained fractional control optimization problems with data uncertainty (MMFP).
