A new approach is proposed for 3-D laser cooling of solids. Stimulated Raman scattering on a narrowband electronic transition is used in conjunction with 1-photon optical pumping on a broadband transition to provide a mechanism that cools all the vibrational modes of solids while conserving energy and momentum, photon by photon. The individual steps in the 2-photon Raman process are 4f–5d and 5...

In this work, we present an adiabatic and nonadiabatic study for all the (1)Sigma(+) states dissociating below the ionic limits [i.e., Na (3s, 3p, 4s, 3d, 4p, 5s, 4d, 4f), K (4s, 4p, 5s, 3d, 5p, 4d, 6s, 4f) and Rb (5s, 5p, 4d, 6s, 6p, 5d, 7s, 4f) + H (1s)]. The ab initio calculations rely on pseudopotential, operatorial core valence correlation and full valence CI (configuration-interaction) ap...

We present some recent progress achieved in the application of symmetry adaptation techniques to n-photon absorption spectroscopy of rare earth ions in finite symmetry. More specifically, this work is concerned with the determination of the intensity of n-photon transitions between Stark levels (rather than J levels) of an ion in an environment with a given symmetry. The role of symmetry is tak...

A porcine rotavirus (prv) monoreassortant, S-F4, which carries RNA segment 4 of the pig-pathogenic variant prv 4F in the genetic background of the pig-apathogenic variant prv 4S (G. I. Tauscher and U. Desselberger, J. Virol. 71:853-857, 1997), was found to be pathogenic in gnotobiotic piglets. This indicates that RNA segment 4 of the pig-pathogenic variant prv 4F is a major determinant of patho...

Dilute Nd in simple cubic LaB(6) shows electrical resistance and specific heat features at low temperature consistent with a Kondo scale of T(K) </~ 0.3 K. Nd has a well-localized 4f(3) J = 9/2 Hund's rule configuration which is not anticipated to be Kondo coupled to the conduction electrons in LaB(6). We conjecture that the unexpected Kondo effect arises via participation of 4f quadrupolar deg...

Figure 4 in the published article shows the same Western blot for two different ages of mice in error, in Fig. 4A and Fig. 4F. The representative blot for IRS in Fig. 4A (third from top) and that for pIRS Tyr in Fig. 4F (first from top) are the same images. The pIRS Tyr in Fig. 4F (first from top) needs to be replaced, and the authors have provided a corrected figure here, as well as the raw bl...

Cellular cardiomyoplasty has emerged as a novel therapy to restore contractile function of injured failing myocardium. Human multipotent muscle derived stem cells (MDSC) can be a potential abundant, autologous cell source for cardiac repair. However, robust conditions for cardiomyocyte (CM) differentiation are not well established for this cell type. We have developed a new method for CM differ...

We have studied the electronic states in three different ceria thin film surfaces prepared on a Cu(111) single-crystal surface by vapor deposition at different conditions: at 250 °C, at room temperature and finally Au-doped ceria film obtained by simultaneous deposition of Au and CeO2 at room temperature (RT). Electronic properties of the layers and interaction of gold with CeO2 were investigat...
