The Second Euler-Lagrange Equation of Variational Calculus on Time Scales
, 2010 The fundamental problem of the calculus of variations on time scales concerns the minimization of a delta-integral over all trajectories satisfying given boundary conditions. In this paper we prove the second Euler-Lagrange necessary optimality condition

Factorization method and general second order linear difference equation
, 2017 This paper addresses an investigation on a factorization method for difference equations. It is proved that some classes of second order linear difference operators, acting in Hilbert spaces, can be factorized using a pair of mutually adjoint first order

Dehnel's Phenomenon in Mammals
Mammal Review, Volume 56, Issue 2, June 2026.Some small mammals, which remain active year‐round, undergo reversible reductions in body size, braincase height, and the mass of internal organs, including the brain, from summer to winter. It is called Dehnel's phenomenon. In this review, we summarise knowledge of the mechanisms, adaptive value, and genetic basis of the phenomenon, and show how new ...

Ecology and Evolution, Volume 16, Issue 5, May 2026.We analysed various points of the counter‐adaptations of the spider egg sac pseudoparasitoid and spiders exhibiting active maternal care, utilising the ichneumonid Hidryta fusiventris and the wolf spider Pardosa lugubris. We observed that there is a time shift of approximately 1 month between the first egg sac of P.

The flare model for X-ray variability of NGC 4258 [PDF]
, 2011 We study the variability mechanism of active galactic nuclei (AGN) within the framework of the flare model. To this end we examine the case of Seyfert/LINER galaxy NGC 4258, which is observed at high inclination angle and exhibits rapid fluctuations of ...
