The SW Sex stars are a class of cataclysmic variables, originally identified because they shared a number of enigmatic properties – most notably, single-peaked emission lines instead of the double-peaked lines one would expect from their high-inclination accretion discs. We present high-time-resolution spectrophotometry of the eclipsing nova-like variables SW Sex and DW UMa, two of the founding...

Silkworm antitrypsin (sw-AT), which was thought to belong to serpin family, changed its behavior against denaturation after chymotryptic cleavage of a single peptide bond (Tyr-Val) two amino acids away from the reactive site for trypsin (Lys-Val). This chymotrypsin-modified sw-AT became resistant to denaturation by heat, sodium dodecyl sulfate, or guanidine hydrochloride, and this characteristi...

The Semantic Web (SW) was originally positioned as a combination of Knowledge Representation (KR) and the Web. However, most applications that use SW data today lean more towards the Information Retrieval spectrum. The reason for this is that traditional KR systems are designed to work with datasets that are small, curated, homogeneous, and application-specific. However, the SW is large-scale, ...

The electronic transport of zigzag-edged graphene nanoribbon (ZGNR) with local Stone-Wales (SW) defects is systematically investigated by first principles calculations. While both symmetric and asymmetric SW defects give rise to complete electron backscattering region, the well-defined parity of the wave functions in symmetric SW defects configuration is preserved. Its signs are changed for the...

BACKGROUND Alzheimer's disease (AD) is considered to be a neurodegenerative disorder that is characterized by increased oxidative stress. Medicinal plants, with their antioxidant properties, have been used to cure several human diseases. The aim of the current study was to explore the protective and therapeutic effect of baicalein on AD-induced rats. MATERIALS AND METHODS Swiss Wistar rats we...

OBJECTIVE Detection of motor imagery of hand/arm has been extensively studied for stroke rehabilitation. This paper firstly investigates the detection of motor imagery of swallow (MI-SW) and motor imagery of tongue protrusion (MI-Ton) in an attempt to find a novel solution for post-stroke dysphagia rehabilitation. Detection of MI-SW from a simple yet relevant modality such as MI-Ton is then inv...

The anadromous salmonid life cycle includes both fresh water (FW) and seawater (SW) stages. The parr-smolt transformation (smoltification) pre-adapt the fish to SW while still in FW. The osmoregulatory organs change their mode of action from a role of preventing water inflow in FW, to absorb ions to replace water lost by osmosis in SW. During smoltification, the drinking rate increases, in the ...

PURPOSE To examine physiological responses to submaximal field running with changes of direction (COD), and to compare two approaches to assess running economy (RE) with COD, ie, during square-wave (SW) and incremental (INC) exercises. METHODS Ten male team-sport athletes performed, in straight-line or over 20 m shuttles, one maximal INC and four submaximal SW (45, 60, 75 and 90% of the veloc...
