How superhydrophobicity breaks down.
A droplet deposited or impacting on a superhydrophobic surface rolls off easily, leaving the surface dry and clean. This remarkable property is due to a surface structure that favors the entrainment of air cushions beneath the drop, leading to the so-called Cassie state. The Cassie state competes with the Wenzel (impaled) state, in which the liquid fully wets the substrate. To use superhydropho...
متن کاملHelicobacter breaks down junctions
and colleagues. Although the bacteria may do it to gain access to tasty chemicals that leak out, the results for humans may include stomach ulcers and gastric cancer. The link from cell junctions to stomach ailments may, say the researchers, lie in tissue repair. Injury to the stomach triggers cell division and migration to plug the gap. The chiefs in charge of these processes may well lie in c...

Security is primary concern for software development projects since their inception. Breaking a software does not necessarily equates “hacking” it, rather it is a phenomenon of exploiting any vulnerabilities in design or implementation of software....
متن کاملAutoimmunity: When self-tolerance breaks down
The spontaneous development of destructive polyarthritis in mice transgenic for an autoreactive T-cell receptor supports the notion that a failure of T-cell self-tolerance can lead to similar diseases in humans, and sheds new light on the role of peripheral tolerance in the avoidance of such pathological immune responses.
متن کاملHow compensation breaks down in Parkinson's disease: Insights from modeling of denervated striatum
The bradykinesia and other motor signs of Parkinson's disease (PD) are linked to progressive loss of substantia nigra dopamine (DA) neurons innervating the striatum. However, the emergence of idiopathic PD is likely preceded by a prolonged subclinical phase, which may be masked by a variety of pre- and postsynaptic compensatory mechanisms. It is often considered self-evident that the signs of P...
