Organisms must faithfully segregate their chromosomes during cell division; mistakes in this process can be costly and even fatal to the organism (1, 2). During mitosis, replicated chromosomes attach to the spindle, a ...

Public agencies have discretion on the time domain, and politicians deploy numerous policy instruments to constrain it. Yet little is known about how administrative procedures that affect timing also affect the quality of ...

The trioxacarcins are structurally complex, highly oxygenated bacterial isolates that potently inhibit the growth of human cancer cells in culture as a consequence of their ability to alkylate guanosine residues of duplex ...

The human genome contains hundreds of regions whose patterns of genetic variation indicate recent positive natural selection, yet for most the underlying gene and the advantageous mutation remain unknown. We developed a ...

Reverberation mapping offers one of the best techniques for studying the inner regions of quasi-stellar objects (QSOs). It is based on cross-correlating continuum and emission-line light curves. New time-resolved optical ...

We present a systematic investigation on the band structure of the GaN_xAs_1−x alloys synthesized using nitrogen ion implantation followed by pulsed-laser melting and rapid thermal annealing. The evolution ...

Let the randomized query complexity of a relation for error probability ϵ be denoted by Rϵ(⋅). We prove that for any relation f⊆{0,1}n× and Boolean function g:{0,1}m→{0,1}, R1/3(f∘gn)=Ω(R4/9(f)⋅R1/2−1/n4(g)), where f∘gn ...

This dissertation is concerned with a particular instance of ambiguity in natural language, between intersective and nonintersective interpretations of certain adjectives. Adjectives like good display a consistent alternation ...

Four experiments investigated 4-year-olds' understanding of adjective-noun compositionality and their sensitivity to statistics when interpreting scalar adjectives. In Experiments 1 and 2, children selected tall and short ...
