The Responder (Rsp) locus of Drosophila melanogaster, the target locus of segregation distortion, is a satellite DNA array. This repeat array imparts some fitness advantage to the chromosomes bearing it. In this paper, we report the following three related molecular properties of this satellite repeat: (1) Sequence-directed curvature--On a polyacrylamide gel, Rsp-containing fragments migrate sl...

A new method for improving the optimization performance of a state-of-the-art differential evolution (DE) variant is proposed in this paper. The technique can increase exploration by adopting long-tailed property Cauchy distribution, which helps algorithm generate trial vector with great diversity. Compared to previous approaches, approach perturbs target instead mutant based on jumping rate. W...

The period estimation and periodic decomposition of a signal are the long-standing problems in the field of signal processing and biomolecular sequence analysis. To address such problems, we introduce the Ramanujan subspace pursuit (RSP) based on the Ramanujan subspace. As a greedy iterative algorithm, the RSP can uniquely decompose any signal into a sum of exactly periodic components, by selec...

BACKGROUND The atrial defibrillation threshold (ADFT) energy of the standard lead configuration, right atrial appendage (RAA) to coronary sinus (CS), was reduced by >50% with the addition of a third electrode traversing the atrial septum in a previous study. This study determined whether the ADFT would be lowered by a more clinically practical third electrode placed in the right atrium along th...

BACKGROUND AND PURPOSE The quality of hospital care for stroke varies, particularly in rural areas. In 2007, funding to improve stroke care became available as part of the Rural Stroke Project (RSP) in New South Wales (Australia). The RSP included the employment of clinical coordinators to establish stroke units or pathways and protocols, and more clinical staff. We aimed to describe the effect...

Surfactant protein (SP) C metabolism was evaluated in vivo by measurements of the clearance of bovine native SP-C (nSP-C) and a recombinant SP-C (rSP-C) in rabbits and mice and in vitro by the uptake into MLE-12 cells. rSP-C is the 34-amino acid human sequence with phenylalanine instead of cysteine in positions 4 and 5 and isoleucine instead of methionine in position 32. Alveolar clearances of ...

BACKGROUND It is important to understand the anatomical relationship between the medial and lateral branches of superficial radial nerve (SRN) and the first dorsal compartment to prevent and minimize possible injury to these nerves during various procedures around the tip of radial styloid process (RSP). OBJECTIVE To delineate the anatomical location of the SRN in relation to the extensor pol...

In Stream Reasoning (SR), empirical research on RDF Stream Processing (RSP) is attracting a growing attention. The SR community proposed methodologies and benchmarks to investigate the RSP solution space and improve existing approaches. In this paper, we present RSPLab, an infrastructure that reduces the effort required to design and execute reproducible experiments as well as share their resul...

The retrosplenial cortex (RSP) and postrhinal cortex (POR) are heavily interconnected with medial temporal lobe structures involved in learning and memory. Previous studies indicate that RSP and POR are necessary for contextual fear conditioning, but it remains unclear whether these regions contribute individually or instead work together as a functional circuit to modulate learning and/or memo...
