The extraction of CKM-matrix-element information from hadronic B-decays generally suffers from discrete ambiguities, hampering the diagnosis of physics beyond the Standard Model. We show that a measurement of the rate asymmetry , which is CP-violating, in B ± → ρ ± ρ 0 (ω) → ρ ± π + π − , where the invariant mass of the π + π − pair is in the vicinity of the ω resonance, can remove the mod(π) u...

From climatology to biofluidics, the characterization of complex flows relies on computationally expensive kinematic and kinetic measurements. In addition, such big data are difficult to handle in real time, thereby hampering advancements in the area of flow control and distributed sensing. Here, we propose a novel framework for unsupervised characterization of flow patterns through nonlinear m...

The bicistronic groESL operon, encoding the Hsp60 and Hsp10 chaperonins, was cloned into an integrative expression vector, pFPN, and incorporated at an innocuous site in the Anabaena sp. strain PCC7120 genome. In the recombinant Anabaena strain, the additional groESL operon was expressed from a strong cyanobacterial P(psbA1) promoter without hampering the stress-responsive expression of the nat...

Pulse-to-pulse variation of the transverse beam orbit, frequently referred to as ' jitter' , has long been a major problem in SLC operation. It impairs the SLC luminosity both by reducing the average beam overlap at the IP and by hampering precision tuning of the final focus. The origin of the fast orbit variation is not fully understood. Measurements during the 1994/95 SLC run showed that it i...

Applying classical association rule extraction framework to dense SAGE data leads to an unmanageably highly sized association rule sets– compounded with their low precision– that often make the perusal of knowledge ineffective, their exploitation time-consuming, and frustrating for the user. To overcome such drawback, we advocate the extraction and exploitation of compact and informative generi...

All work needs to be articulated in terms of “Who should do what, how, when and where”, and this becomes more complicated as more actors are involved. The use of computers in cooperative work implies new needs for articulations due to the individual’s dynamic and changing situation in respect to collective and individual aspects. The computers should mediate both categories of activities, witho...

Content services for mobile phone subscribers compose a new business area based on the constellation of and symbiotic relationship between mobile telecommunication operators and content providers. In this paper we discuss the development and internationalization of the CPA (Content Provider Access) business model and platform by the Norwegian telecommunication operator Telenor. CPA is firmly gr...

Poor Internet connectivity is one of the serious underlying causes of the digital divide between developing and industrialized countries, and is hampering the transition to the global information society. The recent emergence of national and regional research and education data communication networks in parts of the developing world have shown large benefits arising from collaboration amongst t...

We report on our recent detection of the transverse proximity effect of 4 foreground quasars near Q 0302−003 (z = 3.285) as a local hardness fluctuation in the spectral shape of the intergalactic UV radiation field, found by correlating the H I Lyα absorption with the corresponding He II Lyα absorption. We argue that the spectral hardness is a sensitive physical measure to reveal the influence ...

Cloud systems refer to the collection of interconnected servers that are provisioned dynamically on demand, for execution of applications, to the customer like electricity grid. Cloud computing has been drawing the interest from industry but there are still many issues that are in their primitive stage which are hampering the growth of cloud. One of these issues is security of data stored in th...
