We study the multiplicity problem for prime closed orbits of dynamically convex Reeb flows on the boundary of a star-shaped domain in $\mathbb{R}^{2n}$. The first of our two main results asserts that such a flow has at least $n$ prime closed Reeb orb

In this paper we continue investigating connections between Floer theory and dynamics of Hamiltonian systems, focusing on the barcode entropy of Reeb flows. Barcode entropy is the exponential growth rate of the number of not-too-short bars in the Flo

The main result of the paper is that for any closed symplectic manifold the spectral norm of the iterates of a Hamiltonian diffeomorphism is locally uniformly bounded away from zero $C^\infty$-generically.

We investigate the effect of a hyperbolic (or, more generally, isolated as an invariant set) closed Reeb orbit on the dynamics of a Reeb flow on the $(2n-1)$-dimensional standard contact sphere, extending two results previously known for Hamiltonian

Meningiomas are the most common primary tumours of the canine central nervous system. The incidence of these tumours increases with age and they are more frequently encountered in dogs older than seven years. Meningiomas are solitary, well-defined ne

In recent years, significant emphasis has been placed on combination chemotherapy in cancer using cytotoxic agents and plant derived-bioactive substances that are capable of selectively arresting cell growth and inducing apoptosis in tumour cells. Th

An adult, female harbour porpoise (Phocoena phocoena relicta) was found stranded on the southern Aegean Sea coast of Turkey. Thirteen holes made by copepods were observed on the lateral sides of the porpoise. The copepods were identified as Pennella

A Pit-bull and a Beagle, both one-year-old, with complaints of an enlarged clitoris were clinically suspected for hermaphroditism. The enlarged clitoris, the uteri and the gonads were removed surgically from each animal and submitted to our departmen

From a global perspective, hepatocellular carcinoma (HCC) and hydatid cyst disease are both common; however, the endemic and zoonotic nature of hydatid cysts (due to Echinococcus larvae) makes the simultaneous detection of the two conditions a rare o
