Oligodeoxynucleotides with spermine conjugation at C4 of 5-Me-dC ( sp -ODN) exhibit triple helix formation with complementary Watson-Crick duplexes, and were optimally stable at physiological pH 7.3 and low salt concentration. This was attributed to a favored reassociation of the polycationic third strand with the anionic DNA duplex. To gain further insights into the factors that contribute to ...

We consider a family of random walks killed at the boundary of the Weyl chamber of the dual of Sp(4), which in addition satisfies the following property: for any n > 3, there is in this family a walk associated with a reflection group of order 2n. Moreover, the case n = 4 corresponds to a process which appears naturally by studying quantum random walks on the dual of Sp(4). For all the processe...

Fox- mutants of Anabaena sp. strain PCC 7120 are unable to fix dinitrogen in the presence of oxygen. A fragment of the DNA of Anabaena sp. was cloned by complementation of a spontaneous Fox-, cyanophage-resistant mutant, R56, and characterized. Random insertion of transposon Tn5 delimited the complementing DNA to a 0.6-kb portion of the cloned fragment. Sequencing of this region and flanking DN...

In Wireless Sensor Networks (WSNs), localization algorithms could be range-based or range-free. The Approximate Point in Triangle (APIT) is a range-free approach. We propose modification of the APIT algorithm and refer as modified-APIT. We select suitable triangles with appropriate distance between anchors to reduce PIT test errors (edge effect and non-uniform placement of neighbours) in APIT a...

In this paper we obtain new bounds for the minimum output entropies of random quantum channels. These bounds rely on random matrix techniques arising from free probability theory. We then revisit the counterexamples developed by Hayden and Winter to get violations of the additivity equalities for minimum output Rényi entropies. We show that random channels obtained by randomly coupling the inpu...

The GRAVITY Collaboration achieved a remarkable detection of the orbital precession S2 star around Galactic Center supermassive black hole, providing yet another proof validity general relativity. departure from Schwarzschild is encoded in parameter ${f}_{\mathrm{SP}}$, which multiplies predicted relativistic precession. This results ${f}_{\mathrm{SP}}=1.10\ifmmode\pm\else\textpm\fi{}0.19$, con...

Random allele expression has recently been observed for several genes including interleukins and genes of the lymphoid system. We studied the hypothesis that the surfactant protein D (SP-D) gene, an innate host defense molecule, exhibits random allele expression in a tissue-specific manner. SP-D gene expression is tissue specific in the 14 tissues studied. Study of SP-D allelic expression in se...

BACKGROUND Despite the significant benefits of secondary prevention (SP) medication after acute myocardial infarction (MI), evidence suggests that these medications are neither consistently prescribed nor appropriately adhered to by patients. The aim of this study was to investigate the role of general practitioners (GPs) and patients regarding discontinuation of SP medication after MI and reas...
