ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.While flexible TE devices hold promise for converting low‐grade waste heat (e.g., from human skin or electronics) into usable electricity, existing materials suffer from three major limitations: 1) poor mechanical stretchability (failing to match human skin's elongation, ~20–30%), limiting wearability; 2) tradeoffs between thermoelectric efficiency (e ...

Donaldson-Witten theory and indefinite theta functions
, 2017 We consider partition functions with insertions of surface operators of topologically twisted N=2, SU(2) supersymmetric Yang-Mills theory, or Donaldson-Witten theory for short, on a four-manifold.

Alternative Price Dynamics and Valuation of Flexible Strategies
International Journal of Finance &Economics, EarlyView.ABSTRACT In this article, we study the optimal operational strategy of production projects. We investigate different underlying price models and determine the optimal barriers of transition to suspension, recovery, or irreversible abandonment of productive activity.

Singular Sturm?Liouville problems with nonnegative and indefinite weights
Monatshefte f�r Mathematik, 1984 This article is concerned with the oscillatory properties of the eigenfunctions of a class of singular Sturm-Liouville problems \(- (py')'+qy=\lambda wy\) on (a,b), where the weight function w vanishes on a subinterval of positive measure, or where the weight function w changes sign on (a,b).

The Kaohsiung Journal of Medical Sciences, EarlyView.ABSTRACT This study aimed to compare efficacy and safety of ultrasound‐guided erector spinae plane block (ESPB) using liposomal (LB) versus conventional bupivacaine (CB), each plus standardized gabapentin, in patients with postherpetic neuralgia (PHN). A total of 116 PHN patients were randomized to ESPB‐LB or ESPB‐CB; both groups received standardized ...

International Journal of Mechanical System Dynamics, EarlyView.ABSTRACT Hydraulic manipulators exhibit strong coupling, pronounced nonlinearities, and significant modeling uncertainties, which hinder high‐precision motion control. This paper proposes a finite‐time disturbance observer–based nonlinear robust adaptive control (RAC‐FTDO) framework enhanced by a physically consistent dynamic parameter identification ...

Maximum and antimaximum principles for the $p$-Laplacian with weighted Steklov boundary conditions
Electronic Journal of Differential Equations, 2020 We study the maximum and antimaximum principles for the p-Laplacian operator under Steklov boundary conditions with an indefinite weight $$\displaylines{ -\Delta_p u + |u|^{p-2}u = 0 \quad \text{in }\Omega, \cr |\nabla u|^{p-2}\frac{\partial u ...

A global bifurcation result of a Neumann problem with indefinite weight
Electronic Journal of Qualitative Theory of Differential Equations, 2004 This paper is concerned with the bifurcation result of nonlinear Neumann problem \begin{equation} \left\{\begin{array}{lll} -\Delta_p u=& \lambda m(x)|u|^{p-2}u + f(\lambda,x,u)& \mbox{in} \ \Omega\\ \frac{\partial u}{\partial \nu}\hspace{0.55cm}= & 0 &

Obesity, EarlyView.ABSTRACT Objective This study aimed to evaluate whether reduced‐frequency dosing of GLP1 receptor agonists maintains weight loss, body composition, and metabolic syndrome improvements following successful initial treatment with standard weekly therapy. Methods This retrospective case series included 30 adults who achieved weight plateau while on weekly

Principal eigenvalues for indefinite-weight elliptic problems in 𝑅ⁿ [PDF]
Proceedings of the American Mathematical Society, 1992 We consider the problem − Δ u = λ g u - \Delta u = \lambda gu in R n {R^n} , u → 0 u \to 0 at ∞ \infty with g g a function that changes sign.
