The values of sin 2α and sin 2β, where α and β are angles of the unitarity triangle, will be readily measured in a B factory (and maybe also in hadron colliders). We study the standard model constraints in the sin 2α − sin 2β plane. We use the results from recent analyses of fB and τb|Vcb| which take into account heavy quark symmetry considerations. We find sin 2β ≥ 0.15 and most likely sin 2β ...

Effects of the 1-3 leptonic mixing on the solar neutrino observables are studied and the signatures of non-zero θ13 are identified. For this we have re-derived the formula for 3νsurvival probability including all relevant corrections and constructed the iso-contours of observables in the sin θ12−sin θ13 plane. Analysis of the solar neutrino data gives sin θ13 = 0.007 −0.007 (90% C.L.) for ∆m 2 ...

Original antigenic sin describes a phenomenon in which the antibody response elicited in an individual after a secondary viral infection reacts more strongly to the viral variant that originally infected the individual. As T helper cells play critical roles in promoting antibody responses, a similar phenomenon may hold true for T helper cell responses. This concept is particularly relevant to t...

The well-known duality theorem of Pontryagin and van Kampen [27, 20] states that the characters of an Abelian locally compact group G also form a group Ĝ, and the group of characters of Ĝ is isomorphic to G. For non-Abelian groups, there is no such duality. In a few words, difficulties on this way arise from the fact that the dual space of a noncommutative group, however defined, has no natural...

Cytokinesis in the fission yeast Schizosaccharomyces pombe is regulated by a signaling pathway termed the septation initiation network (SIN). The SIN is essential for initiation of actomyosin ring constriction and septum formation. In a screen to search for mutations that can rescue the sid2-250 SIN mutant, we obtained scw1-18. Both the scw1-18 mutant and the scw1 deletion mutant (scw1Delta mut...

1. Hopefully, every group accomplished at least some work this week on project 2. 2. (a) You can do this problem in two ways. The first way is attaching frames to each link and determining the Denavit–Hartenberg parameters, as illustrated in Figure 1. Referring to the figure, the link parameters are: i α i−1 a i−1 d i θ i 1 0 0 0 θ 1 2 0 l 1 0 θ 2 3 0 l 2 0 θ 3 Using equation 3.6 or your Mathem...
