the cu doped nio (nio:cu) nanoparticles were synthesized by co-precipitation method using nicl2.6h2o, cucl2.2h2o for ni and cu sources, respectively. sodium hydroxide has been used as a precipitator agent. effect of cu doping agent on the structural and optical properties of nanostructures were characterized by xrd, sem, afm, spectrophotometry, ftir and vsm techniques. xrd revealed that nio:cu ...

The spectroscopic studies of transition metal complexes of iron. metal complexes, are characterized by XRD, FTIR, H NMR, Mössbauer and VSM (vibrating sample magnetometer) measurements, are reported in the present paper. The XRD analysis reveals the crystalline nature of all the compounds. Mössbauer study interprets paramagnetic nature of complexes at room temperature. VSM measurements also reve...

This paper describes our entry for the Author Identification task at PAN 2013. The Author Identification task was performed using a combination of Vector Space Model [1] (VSM) and Similarity Overlap Metric [3] (SOM) on the character n-grams extracted from the documents related to an author and the document of question. A combination of the VSM and SOM provided an overall F-measure, precision an...

Traditional methods of measuring magnetization in magnetic fluid samples, such as vibrating sample magnetometry (VSM), are typically limited to maximum field strengths of about 1 T. This work demonstrates the ability of MRI to measure the magnetization associated with two commercial MRI contrast agents at 3 T by comparing analytical solutions to experimental imaging results for the field patter...

NMR Biom agnetic fluid samples, such as vibrating sample magnetometry (VSM), are typically limited to maximum field strengths of about 1 T. This work demonstrates the ability of MRI to measure the magnetization associated with two commercial MRI contrast agents at 3 T by comparing analytical solutions to experimental imaging results for the field pattern associated with agents in cylindrical vi...

INTRODUCTION Reduced vascular compliance in patients with hypertension results from an increase in extra-cellular matrix (ECM) protein deposition in blood vessels. At least two key factors, namely mechanical strain and neurohumoral mediators, for example Angiotensin II (Ang II), promote fibrogenesis within vessel walls; however potential interactions between these have not been clearly defined....

Sharma, Ram V., Enqing Tan, Shengyun Fang, Milind V. Gurjar, and Ramesh C. Bhalla. NOS gene transfer inhibits expression of cell cycle regulatory molecules in vascular smooth muscle cells. Am. J. Physiol. 276 (Heart Circ. Physiol. 45): H1450–H1459, 1999.—The mechanisms of nitric oxide (NO)-mediated inhibition of vascular smooth muscle (VSM) cell proliferation are still obscure. Cyclins A and E ...

Cell adhesion-dependent activation of ERK1/2 has been linked functionally to focal adhesion dynamics. We previously reported that in adherent vascular smooth muscle (VSM) cells, CaMKII mediates ERK1/2 activation in response to Ca(2+)-mobilizing stimuli. In the present study, we tested whether CaMKII regulates ERK1/2 signaling in response to VSM cell adhesion. Using an antibody that specifically...

Voltage-gated sodium channels (NaVs) are activated by transiting the voltage sensor from the deactivated to the activated state. The crystal structures of several bacterial NaVs have captured the voltage sensor module (VSM) in an activated state, but structure of the deactivated voltage sensor remains elusive. In this study, we sought to identify peptide toxins stabilizing the deactivated VSM o...

One of the most challenging analysis problems in the data mining and information retrieval domains is organizing large amounts of information. In this paper, we present a fast agglomerative clustering technique used in the Virtual Information Processing Agent Research (VIPAR) project at the Oak Ridge National Laboratory. This approach extends the Vector Space Model (VSM) to provide near real-ti...
