Ultrasound‐guided injections for the retrotrochanteric region: A cadaveric investigation
PM&R, EarlyView.Abstract Background Injections for the piriformis and triceps coxae tendons/bursae have not been described and validated. Objective To investigate the deep retrotrochanteric anatomy and validate an ultrasound (US)‐guided injection technique. Methods Fifteen sides of the pelvic half/lower limb of formalin‐fixed cadaveric specimens were dissected to ...

Plant, Cell &Environment, EarlyView.ABSTRACT Drought is among the most damaging stress for plants, impacting crop yield and grassland sustainability. This study aimed to evaluate the biostimulant effect of an algal extract from Laminaria digitata on Lolium perenne cultivated in a growth chamber. Leaves were sprayed at different concentrations 7 days before stopping irrigation.

Removing scalar curvature assumption for Ricci flow smoothing
Bulletin of the London Mathematical Society, EarlyView.Abstract In recent work of Chan–Huang–Lee, it is shown that if a manifold enjoys uniform bounds on (a) the negative part of the scalar curvature, (b) the local entropy, and (c) volume ratios up to a fixed scale, then there exists a Ricci flow for some definite time with estimates on the solution assuming that the local curvature concentration is small ...

Almost euclidean Isoperimetric Inequalities in spaces satisfying local Ricci curvature lower bounds. [PDF]
, 2017 Motivated by Perelman's Pseudo Locality Theorem for the Ricci flow, we prove that if a Riemannian manifold has Ricci curvature bounded below in a metric ball which moreover has almost maximal volume, then in a smaller ball (in a quantified sense) it ...

Ricci curvature of Bruhat orders
Advances in Applied Mathematics, 2022 We study the Ricci curvature of the Hasse diagrams of the Bruhat order of finite irreducible Coxeter groups. For this purpose we compute the maximum degree of these graphs for types $B_n$ and $D_n$. The proof uses a new graph $Γ(π)$ defined for any element $π$ in the corresponding group.

Chronic and acute mediators of passive viscoelasticity in human skeletal muscle fibres
Experimental Physiology, EarlyView.Abstract The cellular viscoelastic modulus in skeletal muscle tissue responds dynamically to chronic stressors, such as age and exercise. Passive tissue mechanics can also be sensitive to acute stimuli, such as mechanical loading and/or activation‐induced muscle fatigue.

Forman–Ricci communicability curvature of graphs and networks
European Journal of Applied MathematicsGeometric parameters in general and curvature in particular play a fundamental role in our understanding of the structure and functioning of real-world networks. Here, the discretisation of the Ricci curvature proposed by Forman is adapted to capture the

The Journal of Physiology, EarlyView.Abstract figure legend In this study, we use human‐induced pluripotent stem cell‐derived cardiomyocyte (hiPSC‐CM) experiments and computational modelling to identify the mechanism of action of drug compounds. In the hiPSC‐CM experiments, optical measurements of cell collections are recorded in the baseline case and after drug exposure.
