    COVID-19, a viral endocrinological disease?

    Get PDF
    Ever since Chinese health officials informed the WHO of the presence of 44 patients suffering from an anomalous pneumonia apparently linked with the Huanan Seafood Wholesale Market (Wuhan City) on 3rd January 2020, a conspicuous number of scientific publications on COVID-19 have understandably focused either on the main clinical presentation of the novel pathological entity or the response of the immune system to its pathogenic agent, thus following in the footsteps of the established hermeneutical research approach of contemporary infectivological studies..

    Coherent Control of Trapped Bosons

    Full text link
    We investigate the quantum behavior of a mesoscopic two-boson system produced by number-squeezing ultracold gases of alkali metal atoms. The quantum Poincare maps of the wavefunctions are affected by chaos in those regions of the phase space where the classical dynamics produces features that are comparable to hbar. We also investigate the possibility for quantum control in the dynamics of excitations in these systems. Controlled excitations are mediated by pulsed signals that cause Stimulated Raman Adiabatic passage (STIRAP) from the ground state to a state of higher energy. The dynamics of this transition is affected by chaos caused by the pulses in certain regions of the phase space. A transition to chaos can thus provide a method of controlling STIRAP.Comment: 17 figures, Appended a paragraph on section 1 and explained details behind the hamiltonian on section

    Conedy: a scientific tool to investigate Complex Network Dynamics

    Full text link
    We present Conedy, a performant scientific tool to numerically investigate dynamics on complex networks. Conedy allows to create networks and provides automatic code generation and compilation to ensure performant treatment of arbitrary node dynamics. Conedy can be interfaced via an internal script interpreter or via a Python module

    Genghis Khan's death (AD 1227): An unsolvable riddle or simply a pandemic disease?

    Get PDF
    The article examines Genghis Khan's death from the historico-medical perspective. Although several etiologies have been proposed over the years, most of these at a closer look appear to be later inventions by historians. A reassessment of the available evidence suggests instead bubonic plague as the most likely clinical scenario. Genghis Khan's death is also a reflection on the impact of pandemic diseases on leadership in ancient times as well as nowadays

    Flying higher than politics: The goal of preventive medicine at the time of the COVID-19 pandemic

    Get PDF
    Dear Editor-in-Chief,The present SARS-CoV-2-caused COVID-19 pandemic [1] has clearly shown that great health crises can elicit heated political and scientific debates. The history of medicine teaches us how, throughout the centuries, the medical art has seen vicious attacks against pioneers and their discoveries as well as fundamental advances slowed down as a result of such issues

    Pharaoh Tutankhamun: a novel 3D digital facial approximation

    Get PDF
    This article offers a novel and original facial reconstruction of pharaoh Tutankhamun based on data published in the biomedical and Egyptological literature. The reconstruction adopts the Blender 3D software, running the add-on OrtogOnBlender, which allows for a refined presentation of the soft tissues. The present reconstruction is also compared to other approaches produced in the past
