Cation effects on electrochemical CO2 reduction reaction
Next Energy, 2023 Electrochemical CO2 reduction (eCO2RR) to high-value chemicals and fuels, especially oxygenates and long-chain hydrocarbons, are of great interest for industrial applications, as well as offering a feasible strategy to reach the global goal of net-zero ...

A family of global convergent inexact secant methods for nonconvex constrained optimization
Journal of Algorithms & Computational Technology, 2018 We present a family of new inexact secant methods in association with Armijo line search technique for solving nonconvex constrained optimization. Different from the existing inexact secant methods, the algorithms proposed in this paper need not compute ...

Trends in Computational and Applied MathematicsRidge and Lasso regressions are types of linear regression, a machine learning tool for dealing with data. Based on multiobjective optimization theory, we transform Ridge and Lasso regression into bi-objective optimization problems. The Pareto fronts of

TWO TIME-SCALE FEASIBLE DIRECTION METHOD
IFAC Proceedings Volumes, 2005 Abstract Stochastic constrained optimization problems with non-convex objective and convex feasible domain are considered for the case where the objective and constraint functions are available only throuth noisy observations. A general algorithm of the two time-scale stochastic approximation type is proposed for these problems.

Molecular bases of circadian magnesium rhythms across eukaryotes
FEBS Letters, EarlyView.Circadian rhythms in intracellular [Mg2+] exist across eukaryotic kingdoms. Central roles for Mg2+ in metabolism suggest that Mg2+ rhythms could regulate daily cellular energy and metabolism. In this Perspective paper, we propose that ancestral prokaryotic transport proteins could be responsible for mediating Mg2+ rhythms and posit a feedback model ...

Free-Space Quantum Secure Direct Communication: Basics, Progress, and Outlook
Advanced Devices & Instrumentation, 2023 Quantum secure direct communication (QSDC) leverages quantum states to transmit information securely and reliably over a noisy, lossy, and wiretapped quantum channel. It has been proven to be information-theoretically secure. Recent experiments show that

Time after time – circadian clocks through the lens of oscillator theory
FEBS Letters, EarlyView.Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.

An extension of the method of feasible directions [PDF]
, 1975 In this contribution we are going to discuss the extension of the method of feasible directions[1],[2],[3] to programming problems involving an infinite number of constraints. Problems of this type arise frequently in applications. We shall be working with arbitrary convex approximations instead of with linearizations, simply to emphasize the fact that
