On the Strong Approximation of Jump-Diffusion Processes [PDF]

In financial modelling, filtering and other areas the underlying dynamics are often specified via stochastic differential equations (SDEs) of jump-diffusion type.

Acute effect of bounce drop jump and countermovement drop jump with and without additional load on jump performance parameters and reactive strength index on young gymnasts

, 2023
Purpose Reactive strength index defines an athlete’s stretch-shortening cycle function and rebound capabilities. The purpose of the study was to examine the effect of two types of drop jumps (bounce drop jump: BDJ and countermovement drop jump: CDJ) on ...

Effects of three strength training methods on lower extremity strength, jump and sprint performance: a network meta-analysis

Frontiers in Physiology
BackgroundWeightlifting (WT) and Plyometric training (PT) may lead to comparable enhancements in strength, jump, and sprint performance. However, these two training modalities appear to differ significantly in their primary focus and underlying ...

The acute effect of different frequencies of whole-body vibration on range of motion and jump performance in preadolescent karate athletes

Türk Spor ve Egzersiz Dergisi, 2018
Whole-body vibration (WBV) treatments have acute effects on strength, power, and range of motion (ROM) by affecting the nerve-muscle function. However, there is little evidence about what could be the optimal practice for acute WBV.

Golgi enzymes are retrieved from the plasma membrane to the trans‐Golgi network

FEBS Letters, EarlyView.
Golgi enzymes are traditionally considered resident proteins retained within the Golgi apparatus. Here, we demonstrate that a subset transiently reaches the cell surface and is subsequently retrieved to the trans‐Golgi network via retrograde transport. Using a nanobody‐based toolkit, we uncover a dynamic trafficking cycle of several Golgi enzymes.

Force-time metric responses to training in an Olympic 400m sprinter across a two-week microcycle: a case study

Frontiers in Sports and Active Living
Given the underrepresentation of female athletes in the scientific literature, this study investigated changes in neuromuscular performance across a two-week training microcycle in a world-class 400 m sprinter. The microcycle included resistance training,

Ligand‐dependent transcriptional heterogeneity in cell cycle gene expression delays G1/S entry

FEBS Letters, EarlyView.
EGF and HRG induce distinct G1/S progression programs in ErbB2‐amplified BT474 breast cancer cells. Despite activating the potent ErbB2–ErbB3 heterodimer, HRG does not accelerate cell‐cycle entry. Instead, EGF promotes earlier restriction‐point passage via ERK–FOS signaling, whereas HRG activates the AKT–MYC axis, driving transcriptional heterogeneity ...
