A parametrization of the Hamiltonian of the generalized Witten model of the SUSY QM by a single arbitrary function in d = 1 has been obtained for an arbitrary number of the supersymmetries N . Possible applications of this formalism have been discussed. It has been shown that the N = 1 and 2 conformal SUSY QM is generalized for any N . Submitted to the Physics Letters B.

We report on two cases of prenatal diagnosis of myotonic dystrophy (DM), using flanking markers APOC2 or CKMM on the proximal side and D19S51 on the distal side. By double digestion (TaqI and NcoI) of PCR amplified CKMM, the informativeness was increased from a PIC value of 0.57 to 0.69. Altogether, with a PIC value of 0.64 for APOC2, 0.69 for CKMM, and 0.27 for D19S51 (BglI), presymptomatic an...

Forthcoming applications, especially in the multimedia area, require communication services with guaranteed quality of service (QoS). Due to dynamic changes in the network, it is crucial to monitor continuously the achieved QoS during data transmission. This paper focuses on QoS monitoring of ATM connections in end systems as well as inside the ATM network. QM-SSCS, a service specific convergen...

Thought,” university students are told that they are about to participate in a research project aimed at understanding “why differences in social and economic success existbetween graduates of different colleges and universities.” Half of the participants are presented with statistics indicating that alumni members of their own university group are significantly less successful in terms What th...

Many multiple-model (MM) algorithms for tracking maneuvering targets are available, but there are few comparative studies of their performance. This work compares seven MM algorithms for maneuvering target tracking in terms of tracking performance and computational complexity. Six of them are well known and widely used. They are the autonomous multiplemodel algorithm, generalized pseudo-Bayesia...

Searching in a dataset for objects that are similar to a given query object is a fundamental problem for several applications that use complex data. The general problem of many similarity measures for complex objects is their computational complexity, which makes them unusable for large databases. Here, we introduce a study of a variant of a metric tree data structure for indexing and querying ...

The genus Conostigmus Dahlbom (Hymenoptera: Ceraphronoidea: Megaspilidae) is reported for the first time from India, along with description and illustration of Conostigmusneotubifer sp. n. A comparative discussion on the morphological affinities of the new species with its putative sister Conostigmustubifer Dessart is provided. An intermixing of character states of genera Conostigmus as well as...

Acetylation is emerging as a posttranslational modification of nuclear proteins that is essential to the regulation of transcription and that modifies transcription factor affinity for binding sites on DNA, stability, and/or nuclear localization. Here, we present both in vitro and in vivo evidence that acetylation increases the affinity of myogenic factor MyoD for acetyltransferases CBP and p30...
