Optimal cepstrum estimation using multiple windows

The aim of this paper is to find a multiple window estimator that is mean square error optimal for cepstrum estimation. The estimator is compared with some known multiple window methods as well as with the parametric AR-estimator. The results show that the new estimator has high performance, especially for data with large spectral dynamics, and that it is also robust against parameter choices. Sim

Carboxylation of pincer PCP platinum methoxide complexes under formation of metalla carbonates

The ligand 2,6-bis[(diphenylphosphino)methyl]benzene ((PCP)H) was prepared and characterised in an improved manner. With platinum it forms the complex (PCP)PtOTf which reacts with sodium methoxide to give (PCP)PtOMe as the major product together with a small amount of [(PCP)Pt](2)-mu-H. The platinum methoxide reacts with carbon dioxide to give (PCP)PtO(CO)OMe. Also the dinuclear [(PCP)Pt](2)(mu-O(

Modulation of allergen-induced bronchoconstriction by fluticasone furoate and vilanterol alone or in combination

BackgroundThis placebo-controlled study assessed the effects of the once-daily inhaled corticosteroid (ICS) fluticasone furoate (FF) and long-acting beta(2)-agonist (LABA) vilanterol (VI) on early and late asthmatic responses (EAR/LAR) and airway hyper-responsiveness (AHR). MethodsPatients (n=27) were randomized to FF (100g), VI (25g), FF/VI (100/25g), and placebo for 21days (four periods). Allerg

Dissemination of Thrombolysis for Acute Ischemic Stroke Across a Nation. Experiences From the Swedish Stroke Register, 2003 to 2008.

BACKGROUND AND PURPOSE: We used Riks-Stroke, the Swedish Stroke Register, to explore how thrombolysis has been disseminated in Swedish hospitals since it was approved in 2003. METHODS: All 78 hospitals in Sweden admitting patients with acute stroke participate in Riks-Stroke. Between 2003 and 2008, 72 033 adult patients were hospitalized for acute ischemic stroke. We analyzed thrombolysis use by r

Development and application of sedimentary pigments for assessing effects of climatic and environmental changes on subarctic lakes in northern Sweden

A surface-sediment survey of pigments in 100 lakes in the Scandes Mountains, northern Sweden, was combined with a reconstruction of Holocene sedimentary pigments from Lake Seukokjaure to assess the major factors regulating phototrophic communities, and how these controls may have changed during the period from the deglaciation (similar to 9700 cal. years BP) to the present. The study area covers a

Determinant sums for undirected Hamiltonicity

Abstract in UndeterminedWe present a Monte Carlo algorithm for Hamiltonicity detection in an n-vertex undirected graph running in O*(1.657(n)) time. To the best of our knowledge, this is the first superpolynomial improvement on the worst case runtime for the problem since the O*(2(n)) bound established for TSP almost fifty years ago (Bellman 1962, Held and Karp 1962). It answers in part the first

Geographic distribution of need and access to health care in rural population: an ecological study in Iran

Introduction: Equity in access to and utilization of health services is a common goal of policy-makers in most countries. The current study aimed to evaluate the distribution of need and access to health care services among Iran's rural population between 2006 and 2009. Methods: Census data on population's characteristics in each province were obtained from the Statistical Centre of Iran and Natio

Organ bath in detecting the effect of one-hour warm ischemia on pulmonic arteries and bronchi from non-heart-beating donor lungs

Background Non-heart-beating donor lung has been a promising source of lung transplantation. Many studies on non-heart-beating donor lungs are based on animal lung transplantation. In this study, we assessed by organ bath the effect of one-hour warm ischemia on the non-heart-beating donor lung in terms of the integrity of contractile and relaxant functions and tissue structures of pulmonic arterie

Deep SDSS optical spectroscopy of distant halo stars I. Atmospheric parameters and stellar metallicity distribution

Aims. We analyze a sample of tens of thousands of spectra of halo turnoff stars, obtained with the optical spectrographs of the Sloan Digital Sky Survey (SDSS), to characterize the stellar halo population "in situ" out to a distance of a few tens of kpc from the Sun. In this paper we describe the derivation of atmospheric parameters. We also derive the overall stellar metallicity distribution base

Search for direct slepton and gaugino production in final states with two leptons and missing transverse momentum with the ATLAS detector in pp collisions at root s=7 TeV

A search for the electroweak pair production of charged sleptons and weak gauginos decaying into final states with two leptons is performed using 4.7 fb(-1) of proton-proton collision data at root s = 7 TeV recorded with the ATLAS experiment at the Large Hadron Collider. No significant excesses are observed with respect to the prediction from Standard Model processes. In the scenario of direct sle

Search for [Formula: see text] decays in [Formula: see text] collisions at [Formula: see text] = 8 TeV with the ATLAS detector.

A search for a massive [Formula: see text] gauge boson decaying to a top quark and a bottom quark is performed with the ATLAS detector in [Formula: see text] collisions at the LHC. The dataset was taken at a centre-of-mass energy of [Formula: see text] and corresponds to [Formula: see text] of integrated luminosity. This analysis is done in the hadronic decay mode of the top quark, where novel jet

The role of the law enforcement agencies in transport security, a survey with Swedish operators

Transport security, that is, the protection against antagonistic attacks in form of terrorism, theft, counterfeiting, piracy etc. has become a major concern for managers during the last years. The consequences of security incidents include economic losses for industries, but in case of terror attacks may also affect society in general. If transport networks are not adequately protected, consumable
