This is a quick review of CP non-conservation in B physics. Several methods are described for testing the Kobayashi-Maskawa single phase origin of CP violation in B decays, pointing out some limitations due to hadronic uncertainties. A few characteristic signatures of new physics in B decay asymmetries are listed. Invited talk given at the 1999 Chicago Conference on Kaon Physics Chicago, IL, Ju...

In this paper we develop a theory of matrix completion for the extreme case of noisy 1-bit observations. Instead of observing a subset of the real-valued entries of a matrix M , we obtain a small number of binary (1-bit) measurements generated according to a probability distribution determined by the realvalued entries of M . The central question we ask is whether or not it is possible to obtai...

Penuaan kulit terbagi menjadi penuaan intrinsik dan ekstrinsik. ekstrinsik terjadi akibat paparan luar sedangkan merupakan kondisi fisiologis kerusakan DNA. Mekanisme utama adalah reactive oxygen species (ROS). ROS mengaktivasi faktor transkripsi matriks metaloproteinase (MMP). MMP-1 mampu mendegradasi kolagen I III, menyebabkan pengurangan penyebaran/kekuatan mekanis fibroblas pada yang menua,...

the matrix functions appear in several applications in engineering and sciences. the computation of these functions almost involved complicated theory. thus, improving the concept theoretically seems unavoidable to obtain some new relations and algorithms for evaluating these functions. the aim of this paper is proposing some new reciprocal for the function of block anti diagonal matrices. more...

background: this work aimed to show and compare the degradation time of some of cartilage extracellular matrix components using an in vitro model for cartilage degradation induced by interleukin-1 alpha. it is known that elucidation of molecular events under interleukin-1 alpha induction of bovine nasal cartilage could obtain useful data to understand more about involving mechanisms for tissue ...
