A Miniaturized Autonomous Thermomagnetic Generator

open access: yesAdvanced Functional Materials, EarlyView.
Micro, autonomous and high power thermomagnetic generator operating between a heat dissipator and a processor. ABSTRACT Thermomagnetic generators (TMG) are promising devices for converting low‐grade waste heat into electricity. Self‐actuation using permanent magnets is the key to autonomy.

Repeatability of push-up and push-down methods in the measure of accommodation amplitude [PDF]

open access: yes, 2017
La mesura de l’amplitud d’acomodació és una pràctica molt habitual en optometria. La majoria de professionals coincideixen en que els mètodes push-up i push-down són els més utilitzats als exàmens visuals degut al fet que són mètodes ràpids, fàcils i ...

Kinematic Analysis of Four Plyometric Push-Up Variations [PDF]

open access: yes, 2012
International Journal of Exercise Science 5(4) : 334-343, 2012. Plyometric research in the upper extremity is limited, with the effects of open-chain plyometric exercises being studied most.

Switching Superconductivity with Uniaxial Strain in a high‐Tc${\rm T}_{c}$ Cuprate Superconductor

open access: yesAdvanced Functional Materials, EarlyView.
Uniaxial strain is demonstrated as a new scheme for a superconductivity switch. Exploiting the large strain‐induced Tc shift in a cuprate superconductor enables robust switching between superconducting and normal states over 100 cycles with only 0.1% strain.

Dynamic stretching versus plyometric push up training on upper body performance in cricketers

open access: yesThe Rehabilitation Journal
Background: The cricketers may enhance their upper-body performance through dynamic stretching and plyometric push-up training. For tasks specific to cricket, plyometric push-up training promotes explosive strength and power, while dynamic stretching ...

Programming Neuromorphic Plasticity Through Ionic and Electronic Coupling in Organic Electrochemical Transistors

open access: yesAdvanced Functional Materials, EarlyView.
Neuromorphic plasticity in OECTs is governed by the post‐stimulus evolution of coupled ionic and electronic states. Semiconductor chemistry and morphology, electrolyte composition and interfaces, and device architecture regulate ion injection, transport, confinement, and release, shifting responses from rapidly relaxing STP to metastable memory and ...

Loss of amplitude of accommodation in pre-presbyopic HIV and AIDS patients under treatment with antiretrovirals

open access: yesAfrican Vision and Eye Health, 2017
Background: The prevalence of HIV and AIDS is causing an enormous public health burden. Its manifestations spare no organ. Ocular complications are mainly attributed to various opportunistic infections which are directly or indirectly caused by immune ...

Pushing up in Finite Groups

open access: yesJournal of Algebra, 1979
The main result is a pushing up theorem for L3(2n). Let G be a finite group with F*(G) = O2(G). Suppose there exists a normal subgroup H of G with O2(G) ≤ H such that H/O2(G) has no partial complement in G/O2(G) and G/H is isomorphic to L3(2n). Let T be a Sylow 2-subgroup of G and let X be a maximal 2-local subgroup of G containing H with XH/H a ...

Kinetic Analysis of Several Variations of Push-Ups

open access: yesJournal of Strength and Conditioning Research, 2011
Push-ups are a common and practical exercise that is used to enhance fitness, including upper body strength or endurance. The kinetic characteristics of push-ups and its variations are yet to be quantified. Kinetic quantification is necessary to accurately evaluate the training load, and thus the nature of the training stimulus, for these exercise ...

Ultra‐Thin Tow‐Based Discontinuous Composites—Material Overview and Aspirations

open access: yesAdvanced Functional Materials, EarlyView.
Tow‐based discontinuous composites made from ultra‐thin tapes offer outstanding in‐plane mechanical properties. This material, inspired by Nacre, has high volume fraction of tapes exceeding 90 % and allows for quasi‐isotropic material plates less than 100 micrometer in thickness.
