The Effects of Static Stretching on Muscular Hypertrophy During a Resistance Training Program [PDF]

open access: yes, 2013
Studies have shown that static stretching right before physical activity can negatively affect performance. In regards to weight lifting, it has been shown that static stretching immediately prior to lifting can decrease the maximum amount of weight that

Bioorthogonal Engineering of Cellular Microenvironments Using Isonitrile Ligations

open access: yesAdvanced Functional Materials, EarlyView.
Highly selective chemistries are required for fabrication and post‐cross–linking modification of cell‐encapsulating hydrogels used in tissue engineering applications. Isonitrile ligation reactions represent a promising class of bioorthogonal chemistries for engineering hydrogel‐based cellular microenvironments. Isonitrile‐based hydrogels are stable and

Theta liftings on weak Maass forms [PDF]

open access: yesarXiv, 2011
We construct theta liftings from half-integral weight weak Maass forms to even integral weight weak Maass forms by using regularized theta integral. Moreover it gives an extension of Niwa's theta liftings on harmonic weak Maass forms. And we obtain the similar results to those by Niwa.

A semibuoyant vehicle for general transportation missions [PDF]

open access: yes, 1975
The concept of a small, semibuoyant, lifting-body airship with either a disposable or nondisposable buoyant fluid is discussed. Estimations of fuel consumption, payload capability, power requirements and productivity are made and compared to other flight

Smaller = denser, and the brain knows it: natural statistics of object density shape weight expectations. [PDF]

open access: yes, 2015
If one nondescript object's volume is twice that of another, is it necessarily twice as heavy? As larger objects are typically heavier than smaller ones, one might assume humans use such heuristics in preparing to lift novel objects if other informative ...

High‐Speed and Scalable Wet Spinning of Graphene/Liquid Crystalline Elastomer Composite Filaments

open access: yesAdvanced Functional Materials, EarlyView.
Polydomain filaments from graphene/liquid crystalline elastomer (LCE) composites are scalably‐manufactured by wet spinning across a wide range of diameters (≈137–1128 µm) at a speed up to 4500 m h−1 through a double diffusion coagulation mechanism, enabling fast actuation and optimized mechanical performance for broad applications.

Comparison of generalised and directed co-contraction of knee joint muscles during four different movements to strengthen the quadriceps [PDF]

open access: yesJournal of Kerman University of Medical Sciences, 2017
Background: The determinant role of different movements to strengthen the quadriceps on rate of knee joint co-contraction, hamstring to quadriceps muscle activity ratio and vastus medialis to vastus lateralis muscle activity ratio provides useful ...

Emerging non-pharmacological refractory intervention for pain relief in fibromyalgia: A case report [PDF]

open access: yesScripta Medica, 2023
Fibromyalgia (FM) is a common disorder characterised by widespread musculoskeletal pain often associated with fatigue, sleep, memory and mood disturbances. Females are more likely to suffer from FM and experience a reduced quality of life. This is a case

Dynamics simulation of human box delivering task [PDF]

open access: yes, 2018
Thesis (M.S.) University of Alaska Fairbanks, 2018The dynamic optimization of a box delivery motion is a complex task. The key component is to achieve an optimized motion associated with the box weight, delivering speed, and location.

Tunable Tactile Synapses Enabled by Erasable Doping in Iongel‐Gated Nanotube Network Transistors

open access: yesAdvanced Functional Materials, EarlyView.
Artificial tactile synaptic sensors are realized by an iongel‐gated single‐walled carbon nanotube (SWCNT) transistor with reversible doping characteristics. The device senses and memorizes tactile stimuli and exhibits gate bias‐dependent excitatory or inhibitory synaptic behavior.
