Fatigue index and anaerobic power obtained in different surfaces types

Revista Brasileira de Cineantropometria e Desempenho Humano, 2020
Due to the high intensity of competitive sports, the anaerobic power is a very important physical capacity for most sports. However, the diverse surfaces were these sports may interfere in the performance of this capacity.

QBiC-Pred: quantitative predictions of transcription factor binding changes due to sequence variants

Nucleic Acids Res., 2019
Non-coding genetic variants/mutations can play functional roles in the cell by disrupting regulatory interactions between transcription factors (TFs) and their genomic target sites.

Getting a head in hard soils: Convergent skull evolution and divergent allometric patterns explain shape variation in a highly diverse genus of pocket gophers (Thomomys)

BMC Evolutionary Biology, 2016
High morphological diversity can occur in closely related animals when selection favors morphologies that are subject to intrinsic biological constraints.

Hard X-Ray Variability in M82: Evidence for a Nascent Active Galactic Nucleus? [PDF]

, 1999
We report on the detection of hard (2-10 keV) X-ray variability in the starburst galaxy M82 over the course of nine ASCA observations. Long-term variability occurred on a timescale of days, with a change in flux by a factor of up to ~4, corresponding to ...

Volume fluctuations and compressibility of a vibrated granular gas [PDF]

, 2010
The volume fluctuations in the steady state reached by a vibrated granular gas of hard particles confined by a movable piston on the top are investigated by means of event driven simulations.

Study on co-injection molding of poly(styrene-ethylene-butylene-styrene) and polypropylene: Simulation and experiment

Polymer Testing, 2022
In this paper, poly(styrene-ethylene-butylene-styrene) (SEBS) triblock copolymer blends were used as the soft skin material and polypropylene (PP) was used as the hard core for co-injection molding.

The Traveling Salesman Problem Under Squared Euclidean Distances [PDF]

, 2010
Let $P$ be a set of points in $\mathbb{R}^d$, and let $\alpha \ge 1$ be a real number. We define the distance between two points $p,q\in P$ as $|pq|^{\alpha}$, where $|pq|$ denotes the standard Euclidean distance between $p$ and $q$.
