Kernel Bounds for Parabolic Operators Having First‐Order Degeneracy at the Boundary

Mathematische Nachrichten, EarlyView.
ABSTRACT We study kernel estimates for parabolic problems governed by singular elliptic operators ∑i,j=1N+1qijDij+cDyy,cγ+1>0,γ=qN+1,N+1,$$\begin{equation*} \sum _{i,j=1}^{N+1}q_{ij}D_{ij}+c\frac{D_y}{y},\qquad \frac{c}{\gamma }+1>0, \quad \gamma =q_{N+1,N+1}, \end{equation*}$$in the half‐space R+N+1={(x,y):x∈RN,y>0}$\mathbb {R}^{N+1}_+=\lbrace (x,y ...

Thermoresponsive Gel‐Yarn Composites Enable Low‐Temperature Tensile Actuation in Twisted and Coiled Polymer Artificial Muscles

Macromolecular Rapid Communications, EarlyView.
Thermoresponsive gel–yarn composites integrate poly(MAA‐co‐OEGMA) hydrogels with twisted and coiled polyester yarns to enable reversible tensile actuation between 25°C and 50°C. Hydrogel swelling and deswelling generate internal stresses that drive lengthwise actuation, achieving isotonic strains up to 39%.

The functional form of the lognormal distribution as a sum of decaying exponential and sinusoidal terms applied to the isometric pinch force of human fingers

, 2006
The transient data of the pinch force produced between the human forefinger and thumb have been shown to fit the functional form of the well-known lognormal density function.

Accuracy of Two Methods in Estimating Target Muscle Force During Shoulder Submaximal Isometric Contractions

International Journal of Sports Physical Therapy
# Background Submaximal isometric exercises are used for pain control and neuromuscular facilitation. Typically, an ipsilateral maximal voluntary isometric contraction (MVIC) is used as a reference; however, when this is not clinically feasible, an ...

Fragmentation–Coagulation Processes With Advection or Diffusion in Space

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT In this paper, we consider a continuous fragmentation–coagulation model in which the reacting particles can be transported in physical space through either advection or diffusion. We prove new results on the generation of C0$$ {C}_0 $$‐semigroups with parameter and use them to show that the abstract Cauchy problem associated with a more ...

Correlation between architectural variables and torque in the erector spinae muscle during maximal isometric contraction

, 2014
This study analysed whether a significant relationship exists between the torque and muscle thickness and pennation angle of the erector spinae muscle during a maximal isometric lumbar extension with the lumbar spine in neutral position. This was a cross-
