Using the time parameter in time-dependent Schr\"odinger equation, we study of flight for a particle tunneling through square barrier potential. Comparing mean and variance energy transmitted reflected particles, using both density flux distributions, find that, when accounting momentum filtering, suitably normalized distributions are identical cases. In contrast to previous studies, demonstrat...
In forest carbon accounting and policy assessment at the micro level, inconsistencies, even confusion, abound regarding how timber are treated as joint products, whether Paris Agreement principles of additionality permanence followed, if differentiated composition duration harvested wood products (HWPs) captured. Here, we tackle these issues with two widely used alternative analytic frameworks....
In the First Part of this paper [that was submitted for pub. in 1991 and appeared in print in Phys. Reports 214 (1992) 339] we critically review and analyse the main theoretical definitions and calculations of the sub-barrier tunnelling and reflection times. Moreover, we propose a new definition of such durations, on the basis of a recent general formalism of ours (already tested for other type...
We establish Hartman-Wintner type criteria for the half-linear second order differential equation ( r(t)Φ(x′) )′ + c(t)Φ(x) = 0, Φ(x) = |x|x, p > 1, where this equation is viewed as a perturbation of another equation of the same form.
The second order linear differential equation (p(x)y′)′ + q(x)y = 0 , x ∈ (0, x0] is considered, where p, q ∈ C1(0, x0], p(x) > 0, q(x) > 0 for x ∈ (0, x0]. Sufficient conditions are established for every nontrivial solutions to be nonrectifiable oscillatory near x = 0 without the Hartman–Wintner condition.

This paper reports the implementation results of a traffic simulation model based on head leading algorithm. The concept of this algorithm together with a raw model description was presented at ESS2004 last year. The implementation work is currently the main effort. The work is a collaboration together with the city of Pilsen on a complex system that should be able to simulate any part of the c...
In this Roentgen centennial year, honoring the epochal discovery of the X-ray in 1895 [2], it is particularly appropriate to reflect on the circumstances of creativity that lead to important discoveries in science. In radiolc , as in gen. . . . ne and surgery, histories of the development of the discipline have generally presented a chronicle of sequential events without specific consideration ...
