The peculiar Afrotropical bark beetle genus Xyloctonus Eichhoff, 1872 is revised and its biology described.Several unusual morphological features reflect adaptations to predator avoidance as they are highly exposed during mating externally on tree trunks and branches.Observations invariably indicate that males and females abandon the nest under bar
Human genetic factors associated with susceptibility to SARS-CoV-2 infection and COVID-19 disease severity
Abstract Background The emergence of the Collection novel coronavirus in Wuhan, Hubei Province, China, in December 2019 marked the synchronization of the world to a peculiar clock that is counting infected cases and deaths instead of hours and minutes.The pandemic, highly transmissible severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) ha
Motor Neuron Generation from iPSCs from Identical Twins Discordant for Amyotrophic Lateral Sclerosis
Amyotrophic lateral sclerosis (ALS) is a complex neurodegenerative disorder characterized by the loss of the upper and lower motor neurons.Approximately 10% of cases are caused by specific Elastic Watch Strap mutations in known genes, with the remaining cases having no known genetic link.As such, sporadic cases have been more difficult to model exp
Research integrity in times of pandemic
In 1994, Douglas Graham Winch Bumper Altman, one of the greatest statisticians of all time, wrote "We need less research, better research, and research done for good reasons".Twenty-seven years ago, Altman pointed out that the system favored unscientific behavior and that "bad science" was easy to publish, highlighting the financial implications of
Improving the performance of a two-phase ejector using genetic algorithm based on secondary fluid entrainment rate
Ejectors offer a cost-effective and practical solution for recovering flare gases, thereby reducing greenhouse gases.Improving the entrainment rate of the secondary fluid can enhance ejector performance.The objective of this research is to identify the optimal ejector Acrylic Flower Vase geometry to maximize the absorption rate of the secondary flu
