Things Are Heating Up

Application of isothermal titration calorimetry in the biological sciences: things are heating up!

BioTechniques 885 During the last 15 years isothermal titration calorimetry (ITC) has come of age. There are now in excess of 2000 instruments sited in laboratories in more than 40 countries around the world. Research scientists in such diverse fields as biophysics, cell biology, pharmaceutical screening, and food research routinely investigate their systems of interest using ITC. Why is it tha...

Heating up or cooling up the brain? MEG evidence that phrasal verbs are lexical units.

There is a considerable linguistic debate on whether phrasal verbs (e.g., turn up, break down) are processed as two separate words connected by a syntactic rule or whether they form a single lexical unit. Moreover, views differ on whether meaning (transparency vs. opacity) plays a role in determining their syntactically-connected or lexical status. As linguistic arguments could not settle these...

Heating up the cold bounce

Self-dual string cosmological models provide an effective example of bouncing solutions where a phase of accelerated contraction smoothly evolves into an epoch of decelerated Friedmann–Robertson–Walker expansion dominated by the dilaton. While the transition to the expanding regime occurs at sub-Planckian curvature scales, the Universe emerging after the bounce is cold, with sharply growing gau...

Bilattices Are Nice Things

One approach to the paradoxes of self-referential languages is to allow some sentences to lack a truth value (or to have more than one). Then assigning truth values where possible becomes a fixpoint construction and, following Kripke, this is usually carried out over a partially ordered family of three-valued truth-value assignments. Some years ago Matt Ginsberg introduced the notion of bilatti...
