Design of a Multistable Finger Prosthesis with Programmable Metamaterials
Advanced Engineering Materials, EarlyView.This research article shows the development of a multistable programmble metamaterial for the use as a finger prosthesis. The material was designed on different hierarchical levels where the influence of geometrical parameters and combination of mechanical elements was explored.

Energy methods for lossless systems using quadratic differential forms
, 2008 In this thesis, we study the properties of lossless systems using the concept of quadratic differential forms (QDFs). Based on observation of physical linear lossless systems, we define a lossless system as one for which there exists a QDF known as an ...

Time-inconsistent linear-quadratic optimal control for mean-field stochastic equation with jump
Franklin OpenThis paper investigates the time-inconsistency in linear-quadratic optimal control problem for mean-field stochastic equation with jump-diffusion. We introduced the open-loop equilibrium and the closed-loop strategy at first.

Portfolio Optimization in terms of Justifiability Short Selling and Some Market Practical Constraints [PDF]
تحقیقات مالی, 2013 Short-selling prohibition has been one of the primary assumptions of Markowitz mean-variance model. Solving Markowitz quadratic model creates investment efficient frontier by considering only two return and budget constraints.

Investigating the Low‐Temperature Phase Stability of the Binary Ta–W System
Advanced Engineering Materials, EarlyView.Atomistic simulations show that the binary Ta–W system forms ordered intermetallic phases, B2‐TaW and D03‐TaW3, as 0 K ground states. Configurational entropy, however, lowers the free energy of the disordered bcc solid solution, which becomes the stable phase above about 400 K.

Establishment of quadratic exponential quality gain-loss function model and design of process mean
HeliyonTaking into account the fluctuation of the growth rate on the left and right sides of the classic QGLF, a quadratic exponential quality gain-loss function (QGLF) is created based on the asymmetric QGLF.

Advanced Functional Materials, EarlyView.A lead‐free tin‐based hybrid perovskite is designed in which stereochemically active lone‐pair electrons on tin distort the crystal lattice and break its symmetry. Blended into a flexible polymer, the material converts pressure into electricity at milliwatt‐scale power density and continues working far below freezing, powering a commercial wristwatch ...

Role of Structural Disorder on Phonon Transport and Thermal Conductivity in Li6PS5Br
Advanced Functional Materials, EarlyView.Solid electrolytes are fast ion and slow heat conductors. Although both transport properties are governed by lattice dynamics and atomic structure, their interplay remains poorly understood. Here, we study this interrelation in anion‐ordered and disordered Li6PS5Br.
