Reprocessable Vitrimers From Post‐Consumer Polyolefin Blends: Elucidating Phase‐Selective Dynamic Networks

open access: yesMacromolecular Rapid Communications, EarlyView.
Reactive melt extrusion utilizing nitroxide‐mediated silyl ether chemistry transforms post‐consumer high‐density polyethylene and polypropylene blends into robust vitrimers. Featuring highly phase‐selective crosslinking, these upcycled materials combine thermoset‐like dimensional stability at elevated temperatures with dynamic melt‐reprocessability ...

Optimizing range of motion in reverse shoulder arthroplasty: the crucial role of glenoid inclination and lateralization

open access: yesBone & Joint Open
Aims: Optimal glenoid positioning in reverse shoulder arthroplasty (RSA) is crucial to provide impingement-free range of motion (ROM). Lateralization and inclination correction are not yet systematically used.

Developing an RSA Chip [PDF]

open access: yes, 2007
FAF’4 is a fast arithmetic processor designed specifically for modular operations, including exponentiation, on large integers. It is at present implemented as an array of 32-bit bit-slice processors, which may be interconnected without additional circuitry to obtain word lengths of up to 1023 bits.

Reachable Workspace as a Clinical Outcome for Upper Extremity Function: A Narrative Review

open access: yesMuscle &Nerve, EarlyView.
ABSTRACT Motion sensing technology can be utilized to capture detailed upper extremity (UE) motion to reconstruct an individual's three‐dimensional (3D) reachable workspace (RWS). The RWS can be quantified as relative surface area (RSA), providing an innovative surrogate measure to assess UE mobility and function.

The most threatened plants receive the least scientific attention

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Plants sustain all life, providing the energetic and structural basis of ecosystems, but they face a growing risk of extinction. Reversing this decline requires an understanding of how scientific knowledge is distributed among species, and identification of the biases and gaps that hinder effective responses to the threats they face. However, we reveal

Revealing Hidden Impact: Social and Solidarity Economy Enterprise Networks and Sustainable Development in Developing Countries

open access: yesSustainable Development, EarlyView.
ABSTRACT The Social and Solidarity Economy (SSE) offers strong potential for sustainable development in low‐income regions, yet its enterprises often operate with scarce resources, weak monitoring systems, and limited visibility. These constraints hinder both their capacity to demonstrate contributions to sustainable development (SD) and their own ...

Comparison of two Public Key Cryptosystems [PDF]

open access: yesJournal of Optoelectronical Nanostructures, 2018
Since the time public-key cryptography was introduced by Diffie andHellman in 1976, numerous public-key algorithms have been proposed. Some of thesealgorithms are insecure and the others that seem secure, many are impractical, eitherthey have too large ...

From Waste to Value: A Data‐Driven Framework for Sustainable Raw Materials Substitution in the Ceramic Industry

open access: yesSustainable Development, EarlyView.
ABSTRACT With increasing geopolitical risks, environmental pressures, and regulatory demands, the sustainable sourcing of raw materials has become a global priority for achieving the United Nations Sustainable Development Goals (SDGs), particularly SDG 9 (Industry, Innovation and Infrastructure), SDG 12 (Responsible Consumption and Production), and SDG

Three‐dimensional meso‐scale finite element modeling of recycled aggregate concrete using cohesive zone method

open access: yesStructural Concrete, EarlyView.
Abstract The presence of adhered mortar (AM) in recycled aggregates (RAs) significantly affects the mechanical performance of recycled aggregate concrete (RAC). Meso‐scale modeling provides valuable insights into complex phase interactions, enabling a better understanding of RAC behavior.
