Close Is Not Enough
Is membrane fusion an essentially passive or an active process? It could be that fusion proteins simply need to pin two bilayers together long enough, and the bilayers could do the rest spontaneously. Or, it could be that the fusion proteins play an active role after pinning two bilayers, exerting force in the bilayer in one or another way to direct the fusion process. To distinguish these alte...
متن کاملClose, but not close enough
The most recent European Society of Cardiology (ESC) guidelines recommend primary percutaneous coronary intervention (PCI) as the preferred treatment for ST-segment elevation myocardial infarction (STEMI) whenever it is available within 90–120 min of the first medical contact [1]. However, timing of symptom onset appears to be hard to adjudicate precisely, and 'ischaemic time' thereby usually e...

Humans exhibit characteristic success in considering what is relevant in their cognitive tasks. Yet understanding how relevance is determined in cognition remains a problem. This paper seeks to make headway on this problem. The relevance problem is first introduced. Sperber and Wilson’s influential theory of relevance is then discussed, but dismissed as inadequate. Some conditions are identifie...
متن کاملNot Enough Points Is Enough
Models of the untyped λ-calculus may be defined either as applicative structures satisfying a bunch of first order axioms, known as “λ-models”, or as (structures arising from) any reflexive object in a cartesian closed category (ccc, for brevity). These notions are tightly linked in the sense that: given a λ-model A, one may define a ccc in which A (the carrier set) is a reflexive object; conve...
متن کاملWhen Enough Is Not Enough
People are often exposed to more information than they can actually remember. Despite this frequent form of information overload, little is known about how much information people choose to remember. Using a novel “stop” paradigm, the current research examined whether and how people choose to stop receiving new—possibly overwhelming—information with the intent to maximize memory performance. Pa...
