Bogoyavlensky-Volterra and Birkhoff integrable systems
(2004)In this paper we examine an interesting connection between the generalized Volterra lattices of Bogoyavlensky and a special case of an integrable system defined by Sklyanin. The Sklyanin system happens to be one of the ...

Coefficient of variation vs. mean interspike interval curves: What do they tell use about the brain?
(2001)A number of models have been produced recently to explain the high variability of natural spike trains (Softky and Koch, J. Neurosci. 13 (1) (1993) 334). These models use a range of different biological mechanisms including ...

Computational sidechain placement and protein mutagenesis with implicit solvent models
(2007)Structure prediction and computational protein design should benefit from accurate solvent models. We have applied implicit solvent models to two problems that are central to this area. First, we performed sidechain placement ...

Count Time Series Models
(2012)We review regression models for count time series. We discuss the approach that is based on generalized linear models and the class of integer autoregressive processes. The generalized linear models' framework provides ...

An ecological study of the determinants of differences in 2009 pandemic influenza mortality rates between countries in Europe
(2011)Background: Pandemic A (H1N1) 2009 mortality rates varied widely from one country to another. Our aim was to identify potential socioeconomic determinants of pandemic mortality and explain between-country variation. ...

Entropy maximization as a holistic design principle for complex optimal networks
(2006)A general holistic theory is presented for the organization of complex networks. The theory proposes that complex networks, both human-engineered and naturally evolved, are organized to meet certain design or survival ...

HBV-DNA levels predict overall mortality in HIV/HBV coinfected individuals
(2016)The coinfection of Hepatitis B virus (HBV) and human immunodeficiency virus (HIV) has been associated with increased death rates. However, the relevant research has mostly relied on serologic HBV testing [HBV surface antigen ...

Investigation into the charge distribution and barrier profile tailoring in AlGaN/GaN double heterostructures by self-consistent Poisson-Schrödinger calculations and capacitance-voltage profiling
(2002)The two-dimensional electron gas (2DEG) distribution and conduction-band profile tailoring of the Al xGa 1-xN/GaN/Al yGa 1-yN/GaN double heterostructure (DH) has been studied in detail by self-consistent Poisson-Schrödinger ...

Likelihood Estimation for the INAR(p) Model by Saddlepoint Approximation
(2015)Saddlepoint techniques have been used successfully in many applications, owing to the high accuracy with which they can approximate intractable densities and tail probabilities. This article concerns their use for the ...

Migration and HIV epidemic in Greece
(2005)Background: Over the last decade, Greece has experienced a massive influx of migrants from countries in South Eastern/Central Europe, the Middle East, Asia and Africa. This study aimed to estimate the percentage and the ...

Noether and master symmetries for the Toda lattice
(2005)In this letter we examine the interrelation between Noether symmetries, master symmetries and recursion operators for the Toda lattice. The topics include invariants, higher Poisson brackets and the various relations they ...

Observation of the narrow state X(3872) → J/ψπ+π- in p̄p collisions at √s = 1.96 TeV
(2004)The observation of a state consistent with X(3872) decaying into J/ψπ+π- was reported. The X(3872) mass was measured to be 3871.3±0.7(stat)±0.4(syst)MeV/c2 from a sample of 730±90 candidates. The observed width was consistent ...

Poisson approximation for a sum of dependent indicators: An alternative approach
(2002)The random variables X1, X2,...,Xn are said to be totally negatively dependent (TND) if and only if the random variables Xi and Σj≠i Xj are negatively quadrant dependent for all i. Our main result provides, for TND 0-1 ...

Properties of the ubiquitous p-n junction in semiconductor nanowires
(2008)The properties of nanowires with built-in p-n junctions such as the energetic position of the one-dimensional sub-bands, charge distributions and band bending in equilibrium are determined by the self-consistent solution ...

Search for Bs 0 → μ+μ - and Bd 0 → μ+μ - decays in pp̄ collisions at √s = 1.96 TeV
(2004)The decay mechanisms of Bs 0 → μ +μ- and Bd 0 → μ +μ- in pp̄ collisions were investigated. For discrimination of the decays from background events, four variables were used such as invariant mass of muon pair, B-candidate ...

Search for new physics in photon-lepton events in pp̄ collisions at √s = 1.8 TeV
(2002)An a priori search for inclusive photon + lepton production was made. It was found that subsamples of this data set agree well with their standard model (SM) prediction, with the possible exception of γℓ∄T.

Stochastic models for long-term multipath fading channels and their statistical properties
(IEEE, 1999)This paper discusses the use of stochastic differential equations and point processes to model the long-term fading effects during transmission of electromagnetic waves over large areas, which are subject to multipaths and ...
