The LEP investigation of the B 0 d and B 0 s oscillations and of the Cabibbo-Kobayashi-Maskawa matrix element |V ub | improve the constraints on the other elements of this matrix. From a fit to the experimental data and the theory calculations it is possible to determine the vertex of the unitarity triangle as:

systematic and widespread corruption; a problem in russia’s transition period russia is among those countries that are grappled with widespread and systematic corruption in state organizations. meanwhile, different russian governments have failed to reduce the scope of corruption. this article studies nature, roots and repercussions of corruption and analyzes approaches to combat it in russia. ...

for many political observers, the collapse of the soviet :union: would lead to accelerate the process of democratization in all the remained countries from this event, especially russia. but very soon it was clear that the country is confronted with many critical obstacles in this way. the considerable weakness of the civil society and its institutions along with the legacy of centralized power...

This paper presents a new method for computing whether or not two triangles in three dimensions intersect. The code is very efficient and requires minimum arithmetic precision. Indeed, all branching decisions are carried out by evaluating the signs of degree three polynomials. In addition, an efficient test is proposed for the two-dimensional case. Key-words: geometric predicates, low degree pr...

We construct a Teichmüller curve uniformized by the Fuchsian triangle group ∆(m, n, ∞) for every m < n ≤ ∞. Our construction includes the Teichmüller curves constructed by Veech and Ward as special cases. The construction essentially relies on properties of hypergeometric differential operators. For small m, we find bil-liard tables that generate these Teichmüller curves. We interprete some of ...

This paper presents a fast algorithm for generating triangle strips from triangulated meshes, providing a compact representation suitable for transmission and rendering of the models. A data structure that allows efficient triangle strip generation is also described. The method is based on simple heuristics, significantly reducing the number of vertices used to describe the triangulated models....

The excited state dynamics and structure of the photochemically active complex cis-[Ru(bpy)2(py)2](2+) have been investigated using optical transient absorption (OTA) and X-ray transient absorption (XTA) spectroscopy, and density functional theory (DFT). Upon light-excitation in aqueous solution cis-[Ru(bpy)2(py)2](2+) undergoes ultrafast dissociation of one pyridine ligand to form cis-[Ru(bpy)...

Functionality preferences of metathesis Ru carbenes to various alkenes and alkynes with electronic and steric diversity were determined by using time-dependent fluorescence quenching. The functionality preferences depend not only on the properties of multiple bonds but also on the ligands on Ru. There was a good correlation between functionality preference and the metathesis reaction outcome. T...

Along the history, relations between Iran and Russia always faced with great changes and transitions and always, the foundation of these relations have been on the base of political, security and military and sometimes economical affairs. Iran and its people have special identity elements like: Persian language, Shiite Islamism, nationalism, regional hegemonies, anti-foreignism and etc, that so...
