Cell polarization, in which substances previously uniformly distributed become asymmetric due to external or/and internal stimulation, is a fundamental process underlying cell mobility, cell division, and other polarized functions. The yeast cell S. cerevisiae has been a model system to study cell polarization. During mating, yeast cells sense shallow external spatial gradients and respond by c...

Continuum solvation models are widely used to accurately estimate solvent effects on energy, structural and spectroscopic properties of complex molecular systems. The polarizable continuum model (PCM) is one of the most versatile among the continuum models because of the variety of properties that can be computed and the diversity of methods that can be used to describe the solute from molecula...

We present the results of the new optical polarimetric observations of the superluminal source GRO J1655–40, carried out in July 1997, with the multi-channel photopolarimeter of the Torino Observatory, using the 2.15-m telescope of Complejo Astronomico El Leoncito (Argentina). The observed amount of polarization shows (mainly in the V and I bands) oscillations which are consistent with the orbi...

Effects of final state interaction on asymmetries in inclusive scattering of polarized electrons on polarized 3He are investigated using consistent 3He bound state wave function and 3N continuum scattering states. Significant effects are found, which influence the extraction of the magnetic neutron form factor from AT ′ . The enhancement found experimentally for ATL′ near the 3N breakup thresho...

Effects of final state interaction on asymmetries in inclusive scattering of polarized electrons on polarized He are investigated using a consistent He bound state wave function and 3N continuum scattering states. Significant effects are found, which influence the extraction of the magnetic neutron form factor from AT8 . The enhancement found experimentally for ATL8 near the 3N breakup threshol...

An infrared-selected, narrow-line QSO has been found to exhibit an extraordinarily broad Hα emission line in polarized light. Both the extreme width (35,000 km s full-width at zero intensity) and 3,000 km s redshift of the line centroid with respect to the systemic velocity suggest emission in a deep gravitational potential. An extremely red polarized continuum and partial scattering of the nar...

Inelastic scattering of polarized intermediate energy nucleons to continuum nuclear states is discussed with emphasis on recent results. Spin momentum correlations of protons i n polarized targets of 3He were observed for the first time. Complete spin observables in (g$) show effects of the nuclear spin-isospin response and of an NN interaction modified by the nuclear medium. A comparison of Ga...

a new type of backbone robot is presented in this paper. the core idea is to use a cross shape mechanism with the principle of functioning of the scissors linkages, known as a pantograph. although this continuum arm acts quite similar to tendon-driven robot, this manipulator does not include any tendon in its structure. this design does not suffer from the weaknesses of the continuum design suc...
