Generalized quadratic Gauss sums and their 2mth power mean

Open Mathematics
The main purpose of this article is to study the problem of calculating the 2mth power mean of the generalized quadratic Gauss sums, and using the analytic method and an interesting combinatorial identity to give a sharp asymptotic formula for the 2mth ...

Mean Field Linear Quadratic Games with Set Up Costs [PDF]

Dynamic Games and Applications, 2012
In this paper, the following linear-quadratic differential game of \(n\) players with cost functions is considered: the equation for the \(i\)th player reads \[ \begin{cases} \dot{x}_i(t)=u_{i}(t),t\in [0,T),\\ x_i(0)=x^0_i; \end{cases} \] and the cost functional for the \(i\)th player is \[ \int_{0}^{T}\Big(\frac{K \delta (u_i(t))}{a_{i}[t]}+x_i^{2}(t)

Hybrid Auxetic Architectures: Integrating Curvature‐Driven Design for Enhanced Mechanical Tunability and Structural Performance

Advanced Engineering Materials, EarlyView.
Curvature‐tuned auxetic lattices are designed, fabricated, and mechanically characterized to reveal how geometric curvature governs stretchability, stress redistribution, and Poisson's ratio evolution. Photoelastic experiments visualize stress pathways, while hyperelastic simulations quantify deformation mechanics.

Optimal Bounds for Neuman-Sándor Mean in Terms of the Convex Combinations of Harmonic, Geometric, Quadratic, and Contraharmonic Means

Abstract and Applied Analysis, 2012
We present the best possible lower and upper bounds for the Neuman-Sándor mean in terms of the convex combinations of either the harmonic and quadratic means or the geometric and quadratic means or the harmonic and contraharmonic means.

Linear Quadratic Mean Field Game with Control Input Constraint [PDF]

, 2016
In this paper, we study a class of linear-quadratic (LQ) mean-field games in which the individual control process is constrained in a closed convex subset $\Gamma$ of full space $\mathbb{R}^m$.

Thermoelectric Modules Incorporating MgAgSb and Mg3(Sb,Bi)2 Synthesized Using a Melting Method

Advanced Engineering Materials, EarlyView.
A scalable synthesis method for a thermoelectric material of MgAgSb is established. A thermoelectric power module of MgAgSb/Mg3(Sb,Bi)2 is fabricated, showing the conversion efficiency of 7.4% at ΔT = 315 K. The performance is comparable to conventional Bi2Te3 modules when they are operated with an air‐cooled heat exchanger.
