Pacing Spikes All Over
Ventricular safety pacing (VSP) is used to avoid cross talk by delivering ventricular stimulus shortly after an atrial-paced event if ventricular-sensed event occurs. Although VSP is a protective feature that exists for decades in different pacing devices, there are some reports of unfavorable outcomes of this algorithm. More so, health care providers sometimes face difficulties in interpreting...
متن کاملBristling all over
They are runners-up in the Current Biology photomicrography competition. During normal development of the nervous system in Drosophila, a process called 'lateral inhibition' ensures that only a single neural precursor is selected from a group of initially equipotent cells. Where lateral inhibition fails, excess neural cells develop, as shown in the image above, where a 'tuft' of thorn-like bris...
متن کاملBehavior: Warriors Shaking Hands
A basic precondition of social life is that conflicts must be resolved when you need each other. A new study shows that men affiliate more after one-on-one conflicts than women. This reflects the deep evolutionary history of male bonding.
متن کاملShaking Compact Sets
If C is a compact subset of R and H is a halfspace bounded by a hyperplane π, the set C̃ obtained by shaking C on π is defined as the set contained in H, such that for every line ` orthogonal to π, C̃ ∩ ` is a segment of the same length as C ∩ `, and one of its endpoints is on π. It is shown that there exist d + 1 hyperplanes such that every compact set can be reduced to a simplex, via repeated s...
متن کاملHead-shaking nystagmus
Head-shaking nystagmus. Head-Shaking Nystagmus (HSN) is a latent spontaneous vestibular nystagmus provoked by rapid passive head shaking around a vertical axis. HSN is not specific in distinguishing peripheral hypofunction from more central vestibular imbalances. This test is an excellent bedside test for detecting unilateral vestibular hypofunction but further rotatory and caloric testing will...
