Optimal Allocation of Randomly Selected Redundancies to k–Out–of–n System With Independent but Nonidentical Components

open access: yesIEEE Access, 2020
The quality of manufactured components in different batches may be different because of the influence of various stochastic factors. This paper studies the optimal allocation of redundancies drawn from these randomly selected batches to k-out-of-n system

Two-Stage Bi-Objective Stochastic Models for Supplier Selection and Order Allocation Under Uncertainty

open access: yesSystems
In supply chain management practices, supplier selection (SS) is a critical strategic planning activity that usually constitutes an ex ante decision made under uncertainty, whereas order allocation (OA) represents a subsequent operational decision ...

Swelling‐Programmed Topographical Guidance for Dynamic Spheroid Self‐Assembly via a Mechanochemical Hydrogel Niche

open access: yesAdvanced Functional Materials, EarlyView.
A swelling‐programmed micropatterned hydrogel guides adherent cells through a controlled transition from cell–matrix anchoring to cadherin‐mediated cell–cell compaction, enabling rapid assembly of high‐viability spheroids with defined size and morphology.

Birth Order and the Intrahousehold Allocation of Time and Education [PDF]

open access: yes
A potential determinant of intrahousehold distribution is the birth order of children. While a number of studies have analysed birth order effects in developed countries there are still only a few dealing with developing countries.

Rate‐Adaptive Site Transformation Catalyst for Parallel Water Dissociation and Hydrogen Adsorption in Alkaline Hydrogen Evolution

open access: yesAdvanced Functional Materials, EarlyView.
This work presents a rate‐adaptive site transformation strategy in Ag‑ethylenediamine intercalated Co9S8, which not only enables parallel water dissociation and H* adsorption, but also allows the catalyst to provide more active sites under high demand, removing a major bottleneck. The catalyst achieves a record current density of 4.2 A cm−2@2.0 V, with

Mission Impossible!? On the Harmonization of National Allocation Plans under the EU Emissions Trading Directive [PDF]

open access: yes
Starting in 2005, the EU will implement a CO2 emissions trading scheme. In this paper we show that the outspoken goals of economic efficiency and free allocation of allowances are incompatible with harmonized allocation rules.
