This paper presents an integrated portable measurement system for the study of high speed and high temperature unsteady plasma flows such as those found in the vicinity of high current switching arcs. The system permits direct and non-intrusive measurement of arc light emission images with a capture rate of 1 million images per second (1MHz), and 8 bit intensity resolution. Novel software techn...

Previous studies have demonstrated that apoptosis repressor with caspase recruitment domain (ARC) is up-regulated in many forms of malignant tumors and low levels of ARC protein were expressed in normal human brain tissue. Little is known expression of ARC in glioma. Here, we found that ARC protein was highly expressed in primary human glioma when compared with normal brain tissues. A decrease ...

Simultaneous all-sky camera and HF radar observations of the visual and E-region radar aurora in the westward electrojet suggest a close relationship between a pair of parallel east-west-aligned auroral arcs, separated by∼30 km, and a region of strong radar backscatter. Poleward of this a broader region of radar backscatter is observed, though the spectral characteristics of the echoes in these...

Steel has remained the most crucial of all structural materials. However, the steel production processes have changed over the years. Currently, due to the tendency of eliminating high energy consuming technologies, in both the international and domestic steel industry, liquid steel is manufactured in two basic aggregates: oxygen-blown converters and electric arc furnaces 1 . The development of...

This study reports the first detailed geochemical characterization of Kolumbo submarine volcano in order to investigate the role of source heterogeneity in controlling geochemical variability within the Santorini volcanic field in the central Aegean arc. Kolumbo, situated 15 km to the northeast of Santorini, last erupted in 1650 AD and is thus closely associated with the Santorini volcanic syst...

The intersection graph of a family of arcs on a circle is called a circular-arc graph. This class of graphs admits some interesting subclasses: proper circular-arc graphs, unit circular-arc graphs, Helly circular-arc graphs and clique-Helly circular-arc graphs. In this paper, all possible intersections of these subclasses are studied. There are thirteen regions. Twelve of these are nonempty, an...

Arc is a unique immediate early gene (IEG) whose expression is induced as synapses are modified during learning. Newly-synthesized Arc mRNA is rapidly transported throughout dendrites and localizes near recently activated synapses. Arc mRNA levels are regulated by rapid degradation, which is accelerated by synaptic activity in a translation-dependent process. One possible mechanism is nonsense-...

The fuzzy graph approach is more powerful in cluster analysis than the usual graph – theoretic approach due to its ability to handle the strengths of arcs effectively. The concept of node-strength sequence is introduced and is studied in a complete fuzzy graph. Two new connectivity parameters in fuzzy graphs namely, fuzzy node connectivity ðjÞ and fuzzy arc connectivity ðj0Þ are introduced and ...

We have discovered remarkable jetand arc-like molecular features toward the rich and young stellar cluster Westerlund2. The jet has a length of ∼ 100 pc and a width of ∼ 10 pc, while the arc shows a crescent shape with a radius of ∼ 30 pc. These molecular features each have masses of ∼ 10M⊙ and show spatial correlations with the surrounding lower density HI gas. The jet also shows an intriguing...

This paper concerns the shortest path problem for a network in which arc costs can vary with time, each arc has a transit time, parking with a corresponding time-varying cost is allowed at the nodes, and time is modeled as a continuum. The resulting problem is called the continuoustime dynamic shortest path problem, which is well studied in the literature. However, the problem appears as a subp...
