Microengineered Gradient Hydrogels for Mechanobiology

Advanced Healthcare Materials, EarlyView.
Gradient hydrogels are used to mimic the mechanical heterogeneity in native tissues, offering powerful in vitro platforms to study cell‐material interactions in diverse pathophysiological contexts. Here, we present a comprehensive review of the design and experimental considerations for stiffness gradient hydrogels, discussing exemplary achievements ...

Extensions to emergency vehicle location models [PDF]

, 2003
This paper is concerned with extending models for the Maximal Covering Location Problem in two ways. First, the usual 0-1 coverage definition is replaced by the probability of covering a demand within the target time.

Improvements and comparison of heuristics for solving the uncapacitated multisource Weber problem

, 2000
Copyright @ 2000 INFORMSThe multisource Weber problem is to locate simultaneously m facilities in the Euclidean plane to minimize the total transportation cost for satisfying the demand of n fixed users, each supplied from its closest facility.

A Fast Algorithm for Facility Location Problem

Journal of Software, 2013
In this paper, we present an approximation algorithm achieving approximation guarantee of 2 for the classical uncapacitated facility location problem. The distinguishing feature of our designed algorithm is the overall low running time of , where , and are the number of cities and facilities.

Facility layout design with random demand and capacitated machines [PDF]

, 2013
We consider the facility layout problem with machine capacities (and hence multiple machines of each type) and random demand. We develop a very efficient heuristic allowing us to find good solutions to the stochastic case whenever good solutions can be ...

Plasmonic Enhancement of Fluorescence and Protein Dynamics in Living Mammalian Cells

Advanced Materials, EarlyView.
This study demonstrates plasmonic enhancement of the function of fluorescent voltage sensing proteins (genetically encoded voltage indicators, (GEVIs), QuasAr6) in live mammalian cells. Coupling to plasmonic nanoparticles does not just increase fluorescence, but influences the protein photocycle, creating a hybrid sensor with its response speed to ...
