Thwarted dynamics by partial projective measurements

The dynamics of a system, made of a particle interacting with a field mode, “thwarted” by the action of repeated projective measurements on the particle, is examined. The effect of the partial measurements is discussed by comparing it with the dynamics in the absence of the measurements.

The motivation of cows to walk as thwarted by tethering.

Cows are often housed in tie-sheds for some part of the year (from 20 to 80% of adult cows in European countries). By contrast, regulations aiming at improving animal welfare generally provide for more opportunity to express behavior and so limit tethering (the European directive for sows). To inform current debate on whether cows should be tethered from an animal welfare point of view, 2 exper...

Crystal structure of a thwarted mismatch glycosylase DNA repair complex.

The bacterial mismatch-specific uracil-DNA glycosylase (MUG) and eukaryotic thymine-DNA glycosylase (TDG) enzymes form a homologous family of DNA glycosylases that initiate base-excision repair of G:U/T mismatches. Despite low sequence homology, the MUG/TDG enzymes are structurally related to the uracil-DNA glycosylase enzymes, but have a very different mechanism for substrate recognition. We h...

The health promise of Promise Neighborhoods.

The Promise Neighborhoods initiative from the U.S. Department of Education offers grant funding to develop innovative educational and community support programs in distressed communities. Inspired by the success of the Harlem Children's Zone (HCZ), this initiative encourages similarly pioneering approaches to assist low-income children attain academic and social success. An increasing body of e...
