$k$-core percolation on complex networks: Comparing random, localized and targeted attacks [PDF]
Phys. Rev. E 93, 062302 (2016), 2016 The type of malicious attack inflicting on networks greatly influences their stability under ordinary percolation in which a node fails when it becomes disconnected from the giant component. Here we study its generalization, $k$-core percolation, in which a node fails when it loses connection to a threshold $k$ number of neighbors. We study and compare

A stepwise emergence of evolution in the RNA world
FEBS Letters, EarlyView.How did biological evolution emerge from chemical reactions? This perspective proposes a gradual scenario of self‐organization among RNA molecules, where catalytic feedback on random mixtures plays the central role. Short oligomers cross‐ligate, and self‐assembly enables heritable variations. An event of template‐externalization marks the transition to

Skin temperature of middle distance runners after a maximum effort test
Acta Scientiarum. Health Sciences, 2020 The purpose of this study was to analyze skin temperature (Tsk) responses after a short-term maximum effort test in middle-distance runners. A quasi-experimental study was conducted with ten men (age 23.5±5.10 years) who trained 5 days per week, 2 to 3 ...

FEBS Letters, EarlyView.B cells sense external mechanical forces and convert them into biochemical signals through mechanotransduction. Understanding how malignant B cells respond to physical stimuli represents a groundbreaking area of research. This review examines the key mechano‐related molecules and pathways in B lymphocytes, highlights the most relevant techniques to ...

It’s about Time: Effects of Physical Exertion on Duration Estimates [PDF]
Journal of Functional Morphology and Kinesiology, 2019 Background: Task duration is a fundamental aspect of exercise, but little is known about how completed bouts of physical activity are perceived. Consequently, the purpose of the five experiments conducted for this investigation was to examine the effects of engaging in physical tasks on retrospective duration estimates with college student participants.
