The analysis of a Chebyshev problem via spectral matrix theory

Computers & Mathematics with Applications, 2000
A Chebyshev-type problem is considered, namely, to estimate \[ \min_{p \in V_n}{\frac{\int_Jpfw}{\int_Jpgw}}, \] where \(J\) is a closed interval, \(w\) is a weight function, \(f\) and \(g\) are measurable functions such that \(fw\) and \(gw\) belong to \(L^1(J)\), \(gw\) is nonnegative and not essentially identically zero.

Modularity functions maximization with nonnegative relaxation facilitates community detection in networks

, 2011
We show here that the problem of maximizing a family of quantitative functions, encompassing both the modularity (Q-measure) and modularity density (D-measure), for community detection can be uniformly understood as a combinatoric optimization involving ...

Enhancing Synaptic Plasticity and Multistate Retention of Organic Neuromorphic Devices Using Anion‐Excessive Gel Electrolyte

Advanced Functional Materials, EarlyView.
Anion‐excessive gel‐based organic synaptic transistors (AEG‐OSTs) that can maintain electrical neutrality are developed to enhance synaptic plasticity and multistate retention. Key improvement is attributed to the maintenance of electrical neutrality in the electrolyte even after electrochemical doping, which reduces the Coulombic force acting on ...
