Several transitions to higher levels of biological organization have punctuated the history of life. These transitions occur when cooperative alliances lead to the integration of non-identical partners into more complex ...

We describe the propagation of acoustic waves through randomly layered media over distances much larger than the typical wavelength of a pulse that is emitted from a point source. The layered medium is modeled by a smooth ...

Equilibrium concentrations of the major species in conventional and halogen assisted CVD diamond synthesis systems were calculated and the results are presented in this thesis. The optimal diamond deposition conditions ...

Photochemical reactions between benzoquinones and alkylidenecyclohexanes proceed regioselectively. Regioselectivity is determined by the conformational properties of the cyclic olefin. Photocycloadducts thus obtained may ...

Attempting to image the subsurface in areas of complex geology and rapid lateral velocity variation is a challenging problem. In particular, using prestack Kirchhoff migration in conjunction with first arrival travel times ...

This work demonstrates implementations of the discontinuous Galerkin (DG) method on graphics processing units (GPU), which deliver improved computational time compared to the conventional central processing unit (CPU). The ...

Subcellular cargos are transported by enzyme molecules called molecular motors by using the chemical energy from hydrolysis of ATP and performing mechanical work in non-equilibrium. Certain motors tread on cytoskeleton ...

The lac operon has been key in the study of genetic regulation. Consisting of three structural genes and a regulatory domain, the lac operon controls the manufacture of lactose-digesting enzymes in E. coli bacteria. The ...

When two different odorants are presented at the same time to the two nostrils, we experience alternations in olfactory percepts, a phenomenon called binaral rivalry. Little, however, is known about the nature of such ...

What exactly are the "parts" that make up the whole object, and how and when do they group? The answer that is proposed hinges on Emergent Features: features that materialize from the configuration which make the object ...
