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 , , , subject to . The model problem in which the results apply is and . 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 Glanzmannâs 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 ClĂnica da Autocaptura
Os autores fazem uma retrospectiva sobre o tema do ajuste automĂĄtico de limiar de comando ou autocaptura, apresentando suas caracterĂsticas terapĂȘuticas e diagnĂłsticas. Analisam sua influĂȘncia na longevidade do gerador de pulso e na evoluçao dos limiares de comando, agudos ou crĂŽnicos, quando se utilizam os atuais cabos-eletrodos dotados de esterĂłides. Discorrem sobre as possĂveis causas de aumento do limiar de comando apĂłs a maturaçao do cabo-eletrodo e a nova perspectiva que se abre para a obtençao de diagnĂłsticos mais apurados com a utilizaçao do Registro de Limiar de Longo Prazo. Concluem que, dada a atual comprovaçao da eficĂĄcia e dos benefĂcios da autocaptura, esta caracterĂstica Ă© essencial e deve ser incorporada a todos os marcapassos
