Using the most general, model–independent form of effective Hamiltonian, the exclusive, rare B → Kνν̄ decay is analyzed. The sensitivity of the branching ratios and missing mass–squared spectrum to the new Wilson coefficients is discussed.

purpose: to compare rose-k and conventional rgp contact lenses in terms of visual acuity, visual function and comfort in keratoconus patients. method: fifty-four patients with keratoconus were randomly fitted with rose-k and conventional rgp contact lens (wohlk contact lens), by one experienced ophthalmologist using a standard (three touch point) approach. general and demographic information, k...

I present a brief overview of the theoretical status of K 3 decays and their use as probes of lepton universality, light quark mass ratios, and CKM unitarity. I discuss in some detail the constraints imposed on the light quark masses by current measurements of the ratio of charged to neutral K 3 rates. * Speaker. † I would like to thank the organizers for partial financial support and the stimu...

We present and analyze an adaptive chosen ciphertext secure (IND-CCA) identity-based encryption scheme (IBE) based on the well studied Decisional Diffie-Hellman (DDH) assumption. The scheme is provably secure in the standard model assuming the adversary can corrupt up to a maximum of k users adaptively. This is contrary to the Boneh-Franklin scheme which holds in the random-oracle model.

The first part of these notes is an updating (and correction) of [Khat] and is devoted to a paremetrization of the irreducible representations of the (generally disconnected) maximal compact subgroup of a real group in Harish-Chandra’s class. The second part describes how to use that paremetrization of the first part to compute K-type multiplicities in standards modules. (By Frobenius reciproci...

    Background: Nanoscale poly (amidoamine) dendrimers have been investigated for their biological demands, but their antibacterial activity has not been widely discovered. Thus, the sixth generation of poly (amidoamine) dendrimer (PAMAM-G6) was synthesized and its antibacterial activities were evaluated on Gram-negative bacteria; P. aeruginosa, E. coli, A. baumannii, S. typhimur...

Abstract. In this paper we study standard bases for submodules of K[[t1, . . . , tm]][x1, . . . , xn] s respectively of their localisation with respect to a t-local monomial ordering. The main step is to prove the existence of a division with remainder generalising and combining the division theorems of Grauert and Mora. Everything else then translates naturally. Setting either m = 0 or n = 0 w...

with X = νν̄, ll, λq = V ∗ qsVqd. Without the dependence of the loop functions y q on the quark masses, CKM unitarity would imply vanishing FCNC (GIM mechanism). Now, looking at these dependences, combined with the scaling of the CKM elements, one can readily get a handle on the importance of each quark contribution. For X = νν̄, only the Z penguin and W box enter, y q ∼ m 2 q, and light quark co...
