We describe several families of wavelets associated to the Galilei group, extended by space and time dilations. The construction follows a general method based on group representations which are square integrable only on a homogeneous space of the underlying group.

A slightly modified and regularized version of the non-relativistic limit of the relativistic anyon model considered by Jackiw and Nair yields particles associated with the twofold central extension of the Galilei group, with independent spin and exotic structure.

background: in spermatogenesis, spermatogonial cells differentiate to the haploid gametes. it has been shown that spermatogenesis can be done at in vitro condition. in vitro spermatogenesis may provide an open window to treat male infertility. objective: the aim of this study was to evaluate the effects of a novel scaffold containing human serum albumin (hsa)/tri calcium phosphate nanoparticles...

PURPOSE To assess the agreement between the elevation and curvature measurements of the anterior and posterior corneal surfaces obtained using the Galilei Dual Scheimpflug Analyzer and those obtained using the Pentacam single Scheimpflug system. METHODS This prospective, noninterventional, diagnostic study was conducted at the Department of Ophthalmology at the American University of Beirut (...

After defining conformal Galilean-type algebras for arbitrary dynamical exponent z we consider the particular cases of the conformal Galilei algebra (CGA) and the Schrödinger Lie algebra (sch). Galilei massless particles moving with arbitrary, finite velocity are introduced i) in d = 2 as a realization of the centrally extended CGA in 6 dimensional phase space, ii) in arbitrary spatial dimensio...

Starting powders of silicon-substituted beta-tricalcium phosphate (β-TCP/Si) were prepared by the polymerized complex method. Silicon ions blended up to 3.0 mol% total P content. The raw product powder was calcined at 1000 °C, formed into pellets, and sintered 1120 °C for 24 h. resultant bodies showed that a single phase β-type tricalcium (β-TCP) can be obtained with silicon addition 0-2.0 subs...
