Integral measures of weak gravitational lensing by dark-matter haloes, like the aperture mass, are sensitive to different physical halo properties dependent on the halo mass density profile. For isothermal profiles, the relation between aperture mass and virial mass is steeper than for haloes with the universal NFW profile. Consequently, the halo mass range probed by the aperture mass is much w...

This paper proposes a novel technique to exploit discriminative models with subclasses for speech recognition. Speech recognition using discriminative models has attracted much attention in the past decade. However, most discriminative models are still based on tree clustering results of HMM states. On the contrary, our proposed method, referred to as subclass AdaBoost, jointly selects optimal ...

A new approach to the origin of the genetic code is proposed based on some regularities in the nucleotide distribution pattern of the code. The relative amounts of various amino acids in primitive proteins were possibly different from those in organisms living today. The primordial ratio was supposed to shift to the modern one guided by the action of primitive nucleotides. Each primitive tRNA h...

A wide variety of applications require a hard Xray or gamma ray detector which combine both good spatial resolution and energy resolution. Double-sided solid-state strip detectors provide this capability. We report on the development of CMOS electronics designed for photon detection with strip detectors. These electronics include a low noise preamplifier, semi-gaussian shaping amplifier, discri...

IraP is a small protein that interferes with the delivery of sigma(S) (RpoS) to the ClpXP protease by blocking the action of RssB, an adaptor protein for sigma(S) degradation. IraP was previously shown to mediate stabilization of sigma(S) during phosphate starvation. Here, we show that iraP is transcribed in response to phosphate starvation; this response is mediated by ppGpp. The iraP promoter...

Audio information classification becomes a very important task for such purposes as automatic keyword spotting and other content-based audio-visual query system. In this paper, we describe a fast and accurate audio data classification method on MPEG coded data domain. Firstly silent segments are detected using a robust approach for different recording conditions. Then the non-silent segments ar...
