Shor’s algorithm factors an integer N in two steps. The quantum step computes the order of a mod N where a is relatively prime to N . The classical step uses this order to factor N . Descriptions of the classical step require the order, s, to be even and that a 6≡ −1 mod N . If s is odd or a ≡ −1 mod N , then the quantum step is repeated. This paper describes how each prime divisor of the order...
We utilized femtosecond time-resolved resonant inelastic X-ray scattering and ab initio theory to study the transient electronic structure and the photoinduced molecular dynamics of a model metal carbonyl photocatalyst Fe(CO)5 in ethanol solution. We propose mechanistic explanation for the parallel ultrafast intra-molecular spin crossover and ligation of the Fe(CO)4 which are observed following...
A 58-kD cis-Golgi protein has been identified by generating polyclonal antibodies against heavy (cis) Golgi subfractions. Total microsomes isolated from rat pancreatic homogenates were subfractionated to yield a rough microsomal fraction (B1) and three smooth membrane subfractions (B2-B4) enriched in cis-, middle, and trans-Golgi elements, respectively. The heavy (cis) subfraction, B2 (d = 1.17...
This paper describes B2, an extension to BANTER. BANTER is a tutoring shell that allows medical students to practice their decision-making skills by considering a number of medical cases that diier from each other in a controlled manner. The underlying inference engine uses a Bayesian network. B2 provides a natural language interface to BANTER that is consistent with principles for cooperative ...
BACKGROUND Anti B2-Glicoprotein 1 (B2-GPI) is an antiphospholipid antibody that may be present in primary or secondary antiphospholipid syndrome (APS). Systemic Lupus erythematosus (SLE) is the main disease associated with secondary APS. OBJECTIVE To study the prevalence of anti B2-GPI in SLE patients. METHODS Anti B2-GPI (IgM/IgG) was studied by ELISA in 88 patients with SLE of both gender...
We aimed to investigate the frequency of c-erb-B2 expression rate and its association with clinicopathological parameters in our gastric carcinoma series to make a contribution to emerging data on this oncogene. One hundred thirty-nine gastric adenocarcinoma patients underwent total gastrectomy between years 2006 and 2011 were selected to the study. C-erb-B2 expressions were determined by using...
In this research by equilibrium adsorption isotherms of vitamin B2 (Ribo Flavin) on carbon nano-tubes having the multi wall through several discontinues method has been studied.with the help of spectro photometer (UV / VIS) adsorption chart based on the wavelength of vitamin B2 has been obtained, and the relevant graph is plotted .by considering factor of concentration, the concentration necess...
OBJECTIVE The transmembrane ligand ephrin-B2 and its receptor tyrosine kinase EphB4 are specifically expressed on arterial and venous endothelial cells, respectively, and bidirectional signals mediated by both proteins play an important role in vascular development. However, how such bidirectional signals are required for cell-cell adhesion or repulsion remains unclear. METHODS AND RESULTS Us...
We have measured the positions of H2O masers in Sgr B2, a massive star forming region in the Galactic center, relative to an extragalactic radio source with the Very Long Baseline Array. The positions measured at 12 epochs over a time span of one year yield the trigonometric parallax of Sgr B2 and hence a distance to the Galactic center of R0 = 7.9 +0.8 −0.7 kpc. The proper motion of Sgr B2 rel...
Alkaline-earth metal oxides, in particular MgO and CaO dominate Earths lower mantle, therefore, exploring high pressure behavior of this class compounds is significant geophysical research interest. Among all these compounds, BaO exhibits rich polymorphism the range 0-1.5 Mbar. Static enthalpy calculations revealed that undergoes a induced structural phase transition from NaCl-type (B1) $\right...
