Time‐calibrated phylogeny of Daphne (Thymelaeaceae): Pre‐mediterranean temporal origin of the sclerophyllous Daphne gnidium

Journal of Systematics and Evolution, Volume 62, Issue 1, Page 20-37, January 2024.
In this study, we provide evidence to support the historical hypothesis of a pre‐Mediterranean origin (more than 2.8 million years ago), followed by low speciation in sclerophyllous lineages of the Mediterranean Floristic Region. This hypothesis is positively tested by inferring the temporal origin and phylogeography of the sclerophyllous Daphne ...

Quasi-linear Stokes phenomenon for the second Painlev\'e transcendent

, 2001
Using the Riemann-Hilbert approach, we study the quasi-linear Stokes phenomenon for the second Painlev\'e equation $y_{xx}=2y^3+xy-\alpha$. The precise description of the exponentially small jump in the dominant solution approaching $\alpha/x$ as $|x|\to\

Ensuring Security and Privacy in VANET: A Comprehensive Survey of Authentication Approaches

Journal of Computer Networks and Communications, Volume 2024, Issue 1, 2024.
Vehicular ad hoc networks (VANET) are revolutionizing intelligent transportation systems (ITS), and as a result, research on their security is becoming increasingly important. As the primary security concern for VANET, authentication security is still quite difficult to achieve.

Temperature Correlation of Quantum Spins

, 2009
This is a historical note. In 1993 we calculated space, time and temperature dependent correlation function in isotropic version of one dimensional XY spin chain. The correlation function decays exponentially with time and space separation.

Hankel determinant and orthogonal polynomials for the Gaussian weight with a jump

, 2007
We obtain asymptotics in n for the n-dimensional Hankel determinant whose symbol is the Gaussian multiplied by a step-like function. We use Riemann-Hilbert analysis of the related system of orthogonal polynomials to obtain our results.Comment: 34 pages ...
