Copper‐Based Crystalline‐Metallic Glass Composite Thin Films: A Novel Material with Enhanced Strength and Thermally Stable Nanotwins

open access: yesAdvanced Functional Materials, EarlyView.
A Cu‐based crystal‐glass composite with high‐density twins is identified by a fast screening technique using combinatorial sputtering together with XRD and nanoindentation mapping. This bamboo‐like structure demonstrates homogenous plastic flow and retains high strength during in situ high temperature tests, up to 1 GPa at 550°C, owing to those ...

The Association of Relationship Status and Sex-Life Satisfaction With Body Dissatisfaction and Drive for Muscularity in Male Weight-Lifters

open access: yesFrontiers in Psychology, 2019
Relationship status and sexuality are linked to body image concerns, but research on the connection to men’s drive for muscularity (DfM) is scarce. Extreme DfM can lead to a pathological preoccupation with muscularity and problematic eating/exercising ...

Operator pencil passing through a given operator

open access: yes, 2013
Let $\Delta$ be a linear differential operator acting on the space of densities of a given weight $\lo$ on a manifold $M$. One can consider a pencil of operators $\hPi(\Delta)=\{\Delta_\l\}$ passing through the operator $\Delta$ such that any $\Delta_\l$

Intermediate Resistive State in Wafer‐Scale Vertical MoS2 Memristors Through Lateral Silver Filament Growth for Artificial Synapse Applications

open access: yesAdvanced Functional Materials, EarlyView.
In MOCVD MoS2 memristors, a current compliance‐regulated Ag filament mechanism is revealed. The filament ruptures spontaneously during volatile switching, while subsequent growth proceeds vertically through the MoS2 layers and then laterally along the van der Waals gaps during nonvolatile switching.

Modeling the Total Energy Costs of Resistance Exercise: a Work in Progress

open access: yesCentral European Journal of Sport Sciences and Medicine, 2016
We present an aerobic and anaerobic, exercise and recovery energy cost model of intermittent energy costs utilizing task (work, Joules) as opposed to rate (per minute) measurements.

Multibit Ferroelectric HfZrO Memcapacitor for Non‐Volatile Analogue Memory and Reconfigurable Electronics

open access: yesAdvanced Functional Materials, EarlyView.
Ferroelectric memcapacitors enable non‐volatile, voltage‐programmable capacitance tuning for adaptive electronics. A TiN/HfZrO/TiN device stack demonstrates more than eight stable capacitance states within a 24 pF memory window in compact 60 ×$\times$ 60 μm2$\umu{\rm m}^{2}$ devices at low operating voltages.

Effects of isokinetic versus isotonic training and its cessation on total leukocytes and lymphocytes count in adolescent state-level weightlifters

open access: yesInternational Journal of Preventive Medicine, 2018
Background: The study investigated the effects of isokinetic versus isotonic training among adolescent state-level weightlifters in terms of total leukocytes, total lymphocytes, and its subsets following 24 sessions of training program and a month ...
