Performances and Fatigue Responses to Weighted Vest Training in Parkour Novices

open access: yesEuropean Journal of Sport Science, Volume 26, Issue 10, October 2026.
ABSTRACT Weighted vest training has demonstrated benefits for muscle strength, which is critical for parkour performance. However, the acute effects of external loading in this discipline remain poorly understood. This study investigated the impact of weighted vest use during parkour sessions on lower‐limb performance, perceived exertion, and muscle ...

The Relation of Tribinomial Coefficients with Triangular, Catalan and Mersenne Number

open access: yesScience and Technology Indonesia
Numbers are inseparable from mathematics. Each of these types of numbers has its own distinct definition and properties. Numbers are not only used in mathematics, but are also essential in other fields such as philosophy, technology, and science ...

Prime power Sylow numbers [PDF]

open access: yesJournal of Mahani Mathematical Research
In this paper, we study finite groups with a prime-power number of Sylow \(p\)-subgroups. Motivated by the work of Yang et al.~(2022), who characterized non-solvable groups with a prime-power number of Sylow $2$-subgroups, we investigate the ...

Rocking and Rolling of Rigid Polygons Under Seismic Excitation

open access: yesEarthquake Engineering &Structural Dynamics, Volume 55, Issue 12, Page 3161-3180, 10 October 2026.
ABSTRACT We present an event driven analytical framework for rigid cyclic polygons subjected to horizontal ground excitation in which uplift, impact, and successive pivot switching are treated within a unified non‐smooth dynamical description. Rolling is defined as a sequence of energetically admissible transitions between neighbouring vertices tied to

Mersenne Primes in Certain Lucas Sequences [PDF]

open access: yesEPJ Web of Conferences
Prime numbers are the most important numbers in number theory and cryptography. One of such special primes are given by the set of Mersenne primes, that are derived from the form Mn = 2n − 1, where n is a prime number.

Divisors of Mersenne numbers [PDF]

open access: yesMathematics of Computation, 1983
We add to the heuristic and empirical evidence for a conjecture of Gillies about the distribution of the prime divisors of Mersenne numbers. We list some large prime divisors of Mersenne numbers

Spatial optimization to support economically driven decision making for early‐season stand challenges in corn

open access: yesAgrosystems, Geosciences &Environment, Volume 9, Issue 3, September 2026.
Abstract Producers have an interest in mitigating yield and profit penalties associated with stand loss. When damage occurs early in the growing season, producers may opt to replant corn (Zea mays L.) to recoup potential yield losses. Likewise, producers could opt against replanting and accept the loss.

ON THE LARGEST PRIME FACTOR OF THE MERSENNE NUMBERS [PDF]

open access: yesBulletin of the Australian Mathematical Society, 2009
AbstractLetP(k) be the largest prime factor of the positive integerk. In this paper, we prove that the seriesis convergent for each constantα<1/2, which gives a more precise form of a result of C. L. Stewart [‘On divisors of Fermat, Fibonacci, Lucas and Lehmer numbers’,Proc. London Math. Soc.35(3) (1977), 425–447].

Testing for Conformity With Parametric Distributions Using Level Sets: From Univariate to Bivariate Applications

open access: yesStatistical Analysis and Data Mining: An ASA Data Science Journal, Volume 19, Issue 4, August 2026.
ABSTRACT Conformity of observed data with a postulated probability distribution is a fundamental problem of statistical modeling. Current tools for checking distributional conformity are often limited to univariate settings, with extensions to multivariate distributions facing challenges in interpretability and power.
