Non-equilibrium Strain and Elastic Hysteresis in Static and Dynamic Experiments in Sandstones [PDF]

, 2023
The physical origin of hysteretic elasticity in consolidated granular media is still debated. We show that hysteresis in quasi-static experiments (slow loading/unloading cycles) and dynamic acoustoelastic testing (fast perturbation of the sample obtained

Spatial Transformation in Mental Rotation Tasks in Aphantasia [PDF]

, 2022
Aphantasia refers to the inability to summon images to one’s own mind’s eye, resulting in selective deficits of voluntary object imagery. In the present study, we investigated whether M.

Recognizing H-Graphs - Beyond Circular-Arc Graphs [PDF]

, 2023
In 1992 Biró, Hujter and Tuza introduced, for every fixed connected graph H, the class of H-graphs, defined as the intersection graphs of connected subgraphs of some subdivision of H.

Non-equilibrium strain induces hysteresis and anisotropy in the quasi-static and dynamic elastic behavior of sandstones: Theory and experiments

, 2023
Materials with grain contacts or partially closed cracks exhibit anomalous elastic behavior: hysteresis in quasi-static experiments and slow dynamics in fast dynamic ones.

The effect of different wavelengths of light during incubation on the development of rhythmic pineal melatonin biosynthesis in chick embryos

Animal, 2019
Rhythmic pineal melatonin biosynthesis develops in chick embryos incubated under a light (L)-dark (D) cycle of polychromatic white light. The spectral sensitivity of the embryonic pineal gland is not known and was investigated in this study.

Economic Impact of Douglas-fir (Pseudotsuga menziesii [Mirb.] Franco) production in the Czech Republic

Journal of Forest Science, 2014
The article addresses the issues of Douglas-fir (Pseudotsuga menziesii [Mirb.] Franco) production in the Czech Republic (CR). Our analysis shows that the tree species can occupy 149,616-163,713 ha in the CR (with respect to ecological limits set by the ...
