Stress-activated protein kinase/c-Jun N-terminal kinase (SAPK/JNK) is activated by a variety of cellular or environmental stresses. Proper regulation of the SAPK/JNK pathway may be critical for cell survival or death under various conditions. In this study, we report the molecular cloning of novel isoforms of JIP-1, which harbor a putative phosphotyrosine(More)
We search for the decay B ? ! ? in a sample of over 2 million charged B decays using the CLEO detector. We use the channel in which the tau decays leptonically, and combine this lepton with the missing energy and momentum in the event to form a B candidate. A t to the mass and energy distribution of these B candidates yields ?14 46 signal events. This value(More)
We have used the CLEO-II detector at the Cornell Electron Storage Ring to study the inclusive production of charmonium mesons in a sample of 2.15 million BB events. We nd inclusive branching fractions of ( for B!J==X, (0.340.040.03)% for B! 0 X, and (0.400.060.04)% for B! c1 X. We also nd some evidence for the inclusive production of c2. An(More)
We have searched for several two-body charmless hadronic decays of B mesons. These nal states include K and with both charged and neutral kaons and pions data used in this analysis consist of 2:0 fb ?1 taken on the (4S) with the CLEO-II detector at the Cornell Electron Storage Ring (CESR). This data set includes 2.2 million BB pairs, allowing us to place(More)
Characteristics of the dead time of a Geiger-Müller (GM) counter was studied by using a decaying source method and tests were performed for two-parameter dead time models including the general models. Activated (56)Mn was used as the decaying source and the counting rates were observed in one minute steps for 20 half-lives using a GM probe and a(More)
