where is the problem? health scientists are constantly trying to support people by diagnosing, managing the diseases, and improving health in all possible dimensions. attention has been drawn to all aspects of health including biological, psychological, social and spiritual. the problem may lay in behavior, clinical issues, organ cites, genome and epigenome. thus it falls on us, the medical soc...

We will prove the theorem for the case where β = 1/3, the general case follows at the cost of a multiplicative log(1/β) in the sample complexity from a standard amplification argument. To be more precise, we can consider splitting our dataset into O(log(1/β)) sub-datasets and run the β = 1/3 test on each one independently. We return the majority result – since each test is correct with probabil...

In this paper, the consensus problem is investigated for a group of first-order agents in the cooperation-competition network, where agents can cooperate or even compete with each other, i.e., the elements in the coupling weight matrix of the graph can be either positive or negative. In order to solve this consensus problem, the whole network is firstly divided into two sub-networks, i.e., the ...

Nickel(II) complex of [NiL2](ClO4)2, where L is an unsymmetrical tridentate ligand of 2-(2-aminoethyl)imino-3-butanone oximehas been synthesized by a template condensation reaction. The complex was characterized on the basis of microanalytical, spectroscopic, and other physicochemical properties. X-ray diffraction study of the complex revea...

The problem of accurate determination of the position, orientation and width of involute spur gear teeth using a single front-lit image is addressed. The information is used to compute global measures of tooth concentricity and pitch variations across a gear wheel. The approach is based on the use of specialised filters which make maximum use of the grey level information available in the image...

The oxidation of complexes of Ti(III), (TiL6)3+ (L=ur, Meur, DMeur, DEture, N-Bu-ur, and Phur), by iodine as I3- in ethanol and acetonitrile solutions, appears to proceed as a second order reaction and is much faster in ethanol solution (where solvolysis occurs) than in acetonitrile. The enthalpy of activation appears to decrease as ligand's size ...

This paper presents a low-complexity near-maximum-likelihood-detection (near-MLD) algorithm called one-bit-sphere-decoding for an uplink massive multiple-input multiple-output (MIMO) system with one-bit analog-to-digital converters (ADCs). The idea of the proposed algorithm is to estimate the transmitted symbol vector sent by uplink users (a codeword vector) by searching over a sphere, which co...

In this paper, we describe an automatic synthesis procedure that distributes synchronous programs on a set of desynchronized processing elements. Our distribution procedure consists of three steps: First, we translate the given synchronous program to synchronous guarded actions. Second, we analyze their data dependencies and represent them in a so-called action dependency graph (ADG). Third, th...

Abstract In this paper, a two-level Bayesian framework is proposed for the identification of nonlinear hybrid systems from large data sets by embedding it in four-stage procedure. At first stage, feature vector selection techniques are used to generate reduced-size set given training set. The resulting then identify system using method, where objective assign each point corresponding sub-mode m...
