We use affine variety codes and their subfield-subcodes for obtaining quantum stabilizer codes via the CSS code construction. With this procedure we get codes with good parameters, some of them exceeding the quantum Gilbert-Varshamov bound given by Feng and Ma.

background: endotracheal suctioning (ets) is one of the most common supportive measures in intensive care units (icu). ets may be associated with complications including hypoxia and tachycardia. closed system suctioning (css) decreases the rate of cardiorespiratory complication mainly due to continuation of ventilatory support and oxygenation during procedure. css has questionable efficacy, the...

Second language (L2) communication strategies (CSs) have traditionally been dealt with through either interactional or psychological perspectives. However, this paper is a critical attempt to question the status of the particular kinds of psycholinguistic and interactional approaches that currently dominate the field of second language acquisition (SLA). In this way, it expands the significance...

In this article we describe a Semantic Web application for semantic annotation and search in large virtual collections of cultural-heritage objects, indexed with multiple vocabularies. During the annotation phase we harvest, enrich and align collection metadata and vocabularies. The semantic-search facilities support keyword-based queries of the graph (currently 20 M triples), resulting in sema...

By design, mobile computing aims to support numerous expressions of varying interfaces, contexts, and automation. Thus, as mobile computing becomes more prevalent, it is important that designers build systems in support of as many as possible unique, in-use, and user-defined characteristics. We explore these requirements and propose to support them with two existing standardized technologies: H...

OBJECTIVE To quantify and compare variations in oxygen saturation throughout the suctioning procedure (before, during, and after) using two endotracheal suction systems: open suction system (OSS) vs. closed suction system (CSS). METHODS A prospective randomized controlled study was carried out with 39 newborn infants of gestational age ≥ 34 weeks using pressure-limited, time-cycled, continuou...

beta-Scorpion toxins shift the voltage dependence of activation of sodium channels to more negative membrane potentials, but only after a strong depolarizing prepulse to fully activate the channels. Their receptor site includes the S3-S4 loop at the extracellular end of the S4 voltage sensor in domain II of the alpha subunit. Here, we probe the role of gating charges in the IIS4 segment in beta...
