Successive Convex Approximation Algorithms for Sparse Signal Estimation with Nonconvex Regularizations

open access: yes, 2018
In this paper, we propose a successive convex approximation framework for sparse optimization where the nonsmooth regularization function in the objective function is nonconvex and it can be written as the difference of two convex functions. The proposed

Efficient simulation of stochastic chemical kinetics with the Stochastic Bulirsch-Stoer extrapolation method [PDF]

open access: yes, 2014
BackgroundBiochemical systems with relatively low numbers of components must be simulated stochastically in order to capture their inherent noise. Although there has recently been considerable work on discrete stochastic solvers, there is still a need ...

Efficient Process Development for Laser Powder Bed Fusion of a Soft‐Magnetic Metallic Glass Composite

open access: yesAdvanced Engineering Materials, Volume 28, Issue 6, 18 March 2026.
Iron‐based metallic glass alloys exhibit excellent soft‐magnetic properties, and unprecedented geometrical freedom in the design of soft‐magnetic metallic glass components is made possible by additive manufacturing. An efficient workflow for developing parameters for laser‐based powder bed fusion of a Fe‐based metallic glass alloy is presented along ...

Multi‐Tissue Genetic Regulation of RNA Editing in Pigs

open access: yesAdvanced Science, Volume 13, Issue 17, 23 March 2026.
This study presents the first multi‐tissue map of RNA editing and its genetic regulation in pigs. By integrating RNA editing profiles, edQTL mapping, GWAS, and cross‐species comparisons, this work establishes RNA editing as a distinct regulatory layer linking genetic variation to complex traits, highlighting its functional and evolutionary significance.

A Variable Step-Size Unconstrained Adaptive FD-LMS Algorithm for MDM Transmission

open access: yesIEEE Photonics Journal, 2018
Mode-division multiplexing (MDM) over few-mode fibers has been proposed to break through the Shannon limit of the single-mode fiber. Mode coupling and differential mode group delay are two major drawbacks, which limit the performance of the system.

Hybrid Energy Management for Electric Vehicles: Enhancing Battery Lifespan and Efficiency With Marine Predator Algorithm and Dynamic Floating Mechanism

open access: yesEngineering Reports, Volume 8, Issue 3, March 2026.
An intelligent energy management system (IEMS) optimized by the MPA‐DFM approach dynamically regulates battery power using supercapacitor energy in hybrid electric vehicles. The proposed control strategy minimizes battery stress and power loss, extends lifetime, and ensures real‐time stability across transient and steady‐state driving conditions ...

Adaptive stepsize and instabilities in complex Langevin dynamics

open access: yes, 2010
Stochastic quantization offers the opportunity to simulate field theories with a complex action. In some theories unstable trajectories are prevalent when a constant stepsize is employed.
