To understand the role of l-arginine depletion in impaired nitric oxide synthesis in disease, it is important to simultaneously quantify arginine, citrulline, and ornithine in the plasma. Because the three amino acids are endogenous analytes, true blank matrix for them is not available. It is necessary and valuable to compare the performance of different approaches due to lack of regulatory cla...

What distinguishes scenes from nonscenes? Photographs of objects on both naturalistic and blank backgrounds yielded boundary extension (BE: memory for unseen spatial expanse outside the picture's boundaries). However, line-drawn objects on blank backgrounds did not (Experiment 1). Perhaps the blank background was construed as depicting a real-world surface in the photograph condition but was co...

We introduce the recursive, rule-based RDF query language RDFLog. RDFLog extends previous RDF query languages by arbitrary quantifier alternation: blank nodes may occur in the scope of all, some, or none of the universal variables of a rule. In addition RDFLog is aware of important RDF features such as the distinction between blank nodes, literals and URIs or the RDFS vocabulary. The semantics ...

In this article, a 3D finite element simulation of a material accumulation process based on rod end and blank end melting is discussed. This process represents the first step of a two-level cold forming process in microrange and can be modeled mathematically by coupling the Stefan problem with the Navier-Stokes equations including a free capillary surface. Numerical results for melting the tip ...

Deep drawing process is one of the most applicable methods in producing industrial parts. In this process, the initial blank deforms to final product using a rigid punch and die. In this investigation, the effect of deep drawing process parameters of brass/steel laminated sheet composites on required forming force has been investigated. The process simulated using finite element method (FEM) an...

Our MAMBO 1.2 mm blank field imaging survey of ∼ 0.75 sqd has uncovered four unusually bright sources, with flux densities between 10 and 90 mJy, all located in the Abell 2125 field. The three brightest are flat spectrum radio sources with bright optical and X-ray counterparts. Their mm and radio flux densities are variable on timescales of months. Their X-ray luminosities classify them as quas...

Blank cartridge guns are devices that discharge sound and gas, but no bullet or shot. These devices are very similar to real guns in the form of their external design and the sound generated during their firing. Although it is widely held in society that these devices are harmless, reports from Turkey and the world have shown that these guns are not entirely innocent. Herein, we present a 26-ye...

The RDF language (Resource Description Framework) allows nodes in an RDF graph to be unlabeled – “blank nodes”. While blank nodes and certain other features are convenient for RDF authors, their unrestricted use causes complications to RDF consumers, such as when attempting to compare RDF graphs, which in the general case is as difficult as the graph isomorphism problem. This paper proposes a s...
