All-or-none propagated electrical impulses were recorded from the hexactinellid sponge Rhabdocalyptus dawsoni using suction electrodes attached to lumps of aggregated sponge tissue grafted onto the surface of pieces of the same sponge. Impulses were normally evoked by means of externally applied electrical shocks. Recorded externally using an a.c.-coupled amplifier, the electrical event was tri...

Embedded devices in the Internet of Things (IoT) face a wide variety of security challenges. For example, software attackers perform code injection and code-reuse attacks on their remote interfaces, and physical access to IoT devices allows to tamper with code in memory, steal confidential Intellectual Property (IP), or mount fault attacks to manipulate a CPU’s control flow. In this work, we pr...

The influence of whole-body positions on the cerebral blood flow in normal subjects is unclear. Blood flow in cerebral veins and sinuses is continuous, pulsatile and proportional to cerebral blood flow. We examined young healthy volunteers to evaluate peak mean flow velocity (vm) in the straight sinus (SS) assessed by transcranial Doppler sonography in predefined variations of the whole-body pi...

A T-S volumetric census, with a resolution of 0.2°C and 0.1 psu, for years 20-25 of the World Ocean Circulation Experiment Community Modeling Effort eddy-resolving simulation of the equatorial and North Atlantic Ocean, reveals how the thermohalipe character of the model has changed from the initial conditions, which were taken from the Levitus climatology. Any changes in the thermohaline struct...

The effects of polyurethane sponge size and type on the performance of an up-flow sponge bioreactor were studied using different sponge cube sizes (1 x 1 x 1 cm, 2 x 2 x 2 cm and 3 x 3 x 3 cm) and types of sponge (S28-30/45R, S28-30/60R, S28-30/80R and S28-30/90R). The reactors were operated under anaerobic conditions in an early stage and an aerobic condition in a latter stage. The results ind...
