introduction:owing to its favorable radionuclidic characteristics, such as tl/2 = 6.73 day and eβ (max) = 497 kev and ease of its large-scale production using medium flux research reactors, lutetium-177 (177lu) is an attractive radionuclide for various therapeutic applications. no carrier added (nca) 177lu was obtained by thermal neutron bombardment (4×1013n/cm2.s) of 176yb target through 176yb...

Iron is one of the most stubborn impurities in quartz minerals, and iron content partly determines various applications quartz. can exist forms fluid inclusions, lattice impurities. The removal consequent purification minerals are key processes to obtaining high-quality methods including conventional pre-treatment, magnetic separation, acid leaching, microbiological, roasting, flotation, as wel...

Monaural source separation is an interesting area that has received much attention in the signal processing community as it is a pre-processing step in many applications. However, many solutions have been developed to achieve clean separation based on Non-Negative Matrix Factorization (NMF). In this work, we proposed a variant of Itakura-Saito Divergence NMF based on source filter model that ca...

Instrumental neutron activation analysis as carried out at the National Institute of Standards and Technology (NIST) is inadequate for determining Al, Ni, and V at the levels found in the newly prepared Standard Reference Material (SRM) 1577c Bovine Liver. To overcome shortcomings in the value assignment, the authors initiated a cooperative approach using NAA with previously established chemica...

On-line coupling of an automated flow system with a commercially available capillary electrophoresis (CE) system with an electrospray interface (ESI) for mass spectroscopic (MS) detection is described. The peculiarities of CE-ESI-MS interfaces, in which a high electrical field must be applied to the capillary end where the sample is provided by the flow system, introduce significant difficultie...

Selected psychophysical techniques for nonhuman animals are described. These include operant learning methods and a new reflexive technique that may prove especially efficient. Problems of particular interest for toxicological research include control of the physical stimulus, choice of species, separation of stimulus from attentional effects, response bias, and pre- and post-training efficiency.

This extended abstract describes an algorithm which was submitted to the 2008 Music Information Retrieval eXchange in the audio chord detection task. As it is not pre-trained it aims at the n-fold training/testing subtask. Part of this submission is a source separation algorithm which is used to attenuate the main melody. 1

In this study, we report on a method of determining individual velocities of molecular species being separated in a fluid medium within array of nanofluidic channels that can be useful in the detection of molecular species. The method is based on the application of multivariate image analysis methods, in this case principal component analysis and multivariate curve resolution, to temporal image...

Separation logic is a concise method for specifying programs that manipulatedynamically allocated storage. Partially inspired by separation logic, Implicit DynamicFrames has recently been proposed, aiming at first-order tool support. In this paper,we precisely connect the semantics of these two logics. We define a logic whose syntaxsubsumes both that of a standard separation log...
