Hydration structures around F-actin and myosin subfragment-1 (S1), which play central roles as counterparts in muscle contraction, were investigated by small-angle X-ray scattering (SAXS) and small-angle neutron scattering (SANS). The radius of gyration of chymotryptic S1 was evaluated to be 41.3±1.1 Å for SAXS, 40.1±3.0 Å for SANS in H2O, and 37.8±0.8 Å for SANS in D2O, respectively. The value...

This study examined passages containing the fonts, Times New Roman, Courier New, Comic Sans MS, and Arial at 12and 14-point sizes for differences in perceptions of ease of reading, attractiveness, desire to be used in schoolbooks, as well as general font preference when read by children. A significant main effect of font type was found in that Comic Sans MS was perceived as being the easiest to...

While the under-utilization of licensed spectrum based on measurement studies conducted in a few developed countries has spurred lots of interest in opportunistic spectrum access, there exists no infrastructure today for measuring real-time spectrum occupancy across vast geographical regions. In this paper, we present the design and implementation of SpecNet, a first-of-its-kind platform that a...

The neuron-specific guanosine triphosphatase dynamin 1 has been hypothesized to be critically required for pinching off synaptic vesicles during endocytosis. In a recent publication in Science, Ferguson et al. describe a series of experiments demonstrating an unexpectedly selective requirement of dynamin 1 in synaptic vesicle endocytosis only during high frequency (<10 Hz) stimulation, but not ...

RÉSUMÉ . Le handover est le processus qui permet, à un terminal mobile, d’effectuer le passage entre deux points d’attachement à un réseau. Ce changement de point d’attachement implique une déconnexion momentanée du terminal mobile, et des perturbations des communications en cours. Ainsi, pour disposer d’une communication de qualité avec un terminal mobile, le handover doit introduire des mécan...

L’orientation service représente une alternative viable pour le développement d’applications logicielles flexibles. La description d’un service est de nature fonctionnelle faisant référence à des fonctions de base incompréhensibles aux gens du métier, sans mentionner comment ces dernières peuvent répondre aux exigences de l’utilisateur. Le problème qui se pose est la mise en correspondance entr...

Small-angle neutron scattering (SANS) is a powerful technique for characterizing biological systems such as protein solutions. We have used SANS to study the structural modulation in protein solution leading to different phases of protein to crystallization, denaturation and gelation. Studies are carried out on the Bovine Serum Alubmin (BSA) and Lysozyme as model proteins.
