We present a new approach for approximate nearest neighbor queries for sets of high dimensional points under any L t-metric, t = 1; : : : ; 1. The proposed algorithm is eecient and simple to implement. The algorithm uses multiple shifted copies of the data points and stores them in up to (d + 1) B-trees where d is the dimensionality of the data, sorted according to their position along a space ...

Exact extraction of the blood vessels of the retina is an important task in computer-aided diagnosis of retinopathy. This paper describes the development of an automatic image processing fundus and the analytical system to facilitate the diagnosis. The algorithm for the detection of the optical disc, blood vessels and exudates are investigated. The optical disc is identified by the method of th...

poly(vinyl acetate) is synthesized via solution polymerization, and then it is converted to poly(vinyl alcohol) by alkaline alcoholysis. the aim of the work study was to investigate statistically the  influence of reaction variables in vinyl acetate polymerization, the conversion of this monomer to polymer, degree of branching of acetyl group in poly(vinyl acetate), as well as the molecular wei...

E cient reasoning about temporal constraints over nonlinear time models is vital in numerous application areas, such as planning, distributed systems and cooperating agents. We give a total classi cation of tractable classes for the point algebra over partially ordered time and examine one large tractable subclass of the point algebra over branching time.

An asymptotic expansion of the two-loop two-point \master" diagram with two masses m and M, on the mass shell Q 2 = M 2 , is presented. The treatment of the non-analytical terms arising in the expansion around the branching point is discussed. Some details of the calculation of a new class of two-loop integrals are given.

PURPOSE Aim of this study was to establish preliminary data on the variations of arterial supply of thyroid gland in Karnataka population. METHODS The anterior triangles in the neck of formalin fixed cadavers were dissected. The length, branching pattern, number and length of branches of superior thyroid artery (STA) were noted. We measured the length of inferior thyroid artery (ITA) from its...

We investigate the long-time and long-range behavior of branching diffusion processes (starting with a single particle) in two different situations: when the branching potential has compact support and when it is constant. For compactly supported branching potentials, the qualitative behavior of the processes depends on the intensity of the branching. We analyze the super-critical case, when th...

Protein N-glycosylation is a common post-translational modification that produces a complex array of branched glycan structures. The levels of branching, or antennarity, give rise to differential biological activities for single glycoproteins. However, the precise mechanism controlling the glycan branching and glycosylation network is unknown. Here, we constructed quantitative mathematical mode...

| Consider a rooted tree with branching factor b > 1 having b h leafs, each at distance h from the root. Suppose the leafs are assigned real values chosen i.i.d. from some probability density, and the interior nodes of the tree are then also assigned values recursively, according to the negamax rule: The value of a node is the maximum of the negated values of its children. The root will then be...
