Identifying and Indexing Icosahedral Quasicrystals from Powder Diffraction Patterns

We present a scheme to identify quasicrystals based on powder diffraction data and to provide a standardized indexing. We apply our scheme to a large catalog of powder diffraction patterns, including natural minerals, to look for new quasicrystals. Based on our tests, we have found promising candidates worthy of further exploration.Comment: 4 pages, 1 figur

Analysis of a Convective Reaction-Diffusion Equation II

We study the large time behavior of positive solutions of the semilinear parabolic equation $u_t = u_{xx} + \varepsilon (g(u))_x + f(u)$, $0 \u3c x \u3c L$, $\varepsilon \in {\bf R}$, subject to $u(0,t) = u(L,t) = 0$. The model problem in which the results apply is $g(u) = u^m$ and $f(u) = u^p 1 \leqq m \u3c p$. The steady state problem is analyzed in some detail, and results about finite time blow up are proved

Imitation in Large Games

In games with a large number of players where players may have overlapping objectives, the analysis of stable outcomes typically depends on player types. A special case is when a large part of the player population consists of imitation types: that of players who imitate choice of other (optimizing) types. Game theorists typically study the evolution of such games in dynamical systems with imitation rules. In the setting of games of infinite duration on finite graphs with preference orderings on outcomes for player types, we explore the possibility of imitation as a viable strategy. In our setup, the optimising players play bounded memory strategies and the imitators play according to specifications given by automata. We present algorithmic results on the eventual survival of types

Successful unrelated donor cord blood transplantation for Glanzmann’s thrombasthenia

GT, a rare disorder of platelet function, can lead to life-threatening bleeding, particularly following the development of antiplatelet antibodies. Curative therapy includes HCT but previous reports are limited predominantly to matched siblings and have excluded CBT. Delayed or non-engraftment of platelets because of antiplatelet antibodies might be particularly concerning after CBT for GT. Here, we report two successful unrelated cord blood transplants for GT. Recurrent life-threatening bleeding was the primary indication for HCT, with one patient developing antiplatelet antibodies pre-HCT. Bleeding risks associated with delivery of the conditioning regimen and the toxicity that follows should be carefully considered, including tunneled central venous line catheter placement, inclusion of B cell-specific therapy to potentially decrease antiplatelet antibody production, and targeted busulfan dosing. This is the first report of successful unrelated cord blood HCT for GT and indicates that modifications to supportive care can improve the safety of this potentially curative therapy for patients with severe, life-threatening disease manifestations.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/78580/1/j.1399-3046.2009.01251.x.pd

Utilizaçao Clínica da Autocaptura

Os autores fazem uma retrospectiva sobre o tema do ajuste automático de limiar de comando ou autocaptura, apresentando suas características terapêuticas e diagnósticas. Analisam sua influência na longevidade do gerador de pulso e na evoluçao dos limiares de comando, agudos ou crônicos, quando se utilizam os atuais cabos-eletrodos dotados de esteróides. Discorrem sobre as possíveis causas de aumento do limiar de comando após a maturaçao do cabo-eletrodo e a nova perspectiva que se abre para a obtençao de diagnósticos mais apurados com a utilizaçao do Registro de Limiar de Longo Prazo. Concluem que, dada a atual comprovaçao da eficácia e dos benefícios da autocaptura, esta característica é essencial e deve ser incorporada a todos os marcapassos
