Impact of atrial fibrillation/flutter on the in-hospital mortality of ischemic stroke patients.

2020

Stroke is the second leading cause of death worldwide. Ischemic strokes, which are caused by atrial fibrillation/flutter (AF), may be more devastating than those that occur without AF.The purpose of this study was to investigate the impact of AF on adverse events in hospitalized ischemic stroke patients and to estimate the elevated impact of AF on the occurrence of these adverse events.The nationwide German inpatient sample of the years 2005-2015 was used for this analysis. Ischemic stroke patients were identified by ICD code I63 and stratified by AF. Logistic regression models were used to investigate the impact of AF on adverse in-hospital events and adjusted for age, sex, and comorbiditi…

Penning-trap mass measurements on 92, 94-98, 100Mo with JYFLTRAP

2012

Penning-trap measurements on stable 92, 94-98, 100Mo isotopes have been performed with relative accuracy of \ensuremath1⋅10−8\ensuremath1⋅10−8 with the JYFLTRAP Penning-trap mass spectrometer by using 85Rb as a reference. The Mo isotopes have been found to be about 3keV more bound than given in the Atomic Mass Evaluation 2003 (AME03). The results confirm that the discrepancy between the ISOLTRAP and JYFLTRAP data for 101-105Cd isotopes was due to an erroneous value in the AME03 for 96Mo used as a reference at JYFLTRAP. The measured frequency ratios of Mo isotopes have been used to update mass-excess values of 30 neutron-deficient nuclides measured at JYFLTRAP. peerReviewed

Robust Discrete-Time Lateral Control of Racecars by Unknown Input Observers

2023

This brief addresses the robust lateral control problem for self-driving racecars. It proposes a discrete-time estimation and control solution consisting of a delayed unknown input-state observer (UIO) and a robust tracking controller. Based on a nominal vehicle model, describing its motion with respect to a generic desired trajectory and requiring no information about the surrounding environment, the observer reconstructs the total force disturbance signal, resulting from imperfect knowledge of the time-varying tire-road interface characteristics, presence of other vehicles nearby, wind gusts, and other model uncertainty. Then, the controller actively compensates the estimated force and as…

Individual and environmental factors underlying life space of older people – study protocol and design of a cohort study on life-space mobility in ol…

2012

Abstract Background A crucial issue for the sustainability of societies is how to maintain health and functioning in older people. With increasing age, losses in vision, hearing, balance, mobility and cognitive capacity render older people particularly exposed to environmental barriers. A central building block of human functioning is walking. Walking difficulties may start to develop in midlife and become increasingly prevalent with age. Life-space mobility reflects actual mobility performance by taking into account the balance between older adults internal physiologic capacity and the external challenges they encounter in daily life. The aim of the Life-Space Mobility in Old Age (LISPE) p…

Assessment of methodologies and data used to calculate desalination costs

2017

Abstract In desalination, similarly with other industries, the cost of the final product is one of the most important criteria that define the commercial success of a specific technology. Therefore, when new projects are planned or new technologies are proposed, the analysis of the expected costs attracts a lot of attention and is compared to (perceived) costs of state-of-the-art desalination or costs of alternative fresh water supply options. This comparison only makes sense if the cost assessment methodologies are based on the same principles and use common assumptions. This paper assesses: (i) the methodologies used to calculate the water cost; (ii) the boundary conditions and (iii) the …

Factors associated with influenza vaccination of hospitalized elderly patients in Spain

2016

Vaccination of the elderly is an important factor in limiting the impact of influenza in the com- munity. The aim of this study was to investigate the factors associated with influenza vacci- nation coverage in hospitalized patients aged 65 years hospitalized due to causes unrelated to influenza in Spain. We carried out a cross-sectional study. Bivariate analysis was performed comparing vaccinated and unvaccinated patients, taking in to account sociodemographic variables and medical risk conditions. Multivariate analysis was per- formed using multilevel regression models. We included 1038 patients: 602 (58%) had received the influenza vaccine in the 2013 - 14 season. Three or more general p…

Usefulness of echocardiography in the assessment of internal medicine inpatients: An analysis according to ACC/AHA guidelines

1999

BACKGROUND: We aimed to analyze the importance of echocardiography in our Internal Medicine Institute. We think that this technique could have a large impact in the evaluation of the internistic inpatient who is usually affected by multiple pathological problems. METHODS: Analysis was performed according to the ACC/AHA guidelines for the application of echocardiography. The data of 1211 consecutive inpatients were analyzed. RESULTS: Sixty-three per cent of all the patients had two or more associated diseases. Moreover, patients in whom echocardiography could be considered appropriate or useful were 67%. Our results point out that echocardiographic examination is generally a technique of gre…

Parameter identification of linear induction motor model in extended range of operation by means of input-output data

2012

This paper proposes a technique for the off-line estimation of the electrical parameters of the equivalent circuit of linear induction machines (LIM), taking into consideration the end effects, and focuses on the application of an algorithm based on the minimization of a suitable cost function involving the differences of measured and computed by simulation inductor current components. This method exploits an entire start-up transient of the LIM to estimate all the 4 electrical parameters of the machine (Rs, L s, σ Ls, Tr). It proposes also a set of tests to be made to estimate the variation of the magnetic parameters of the LIM versus the magnetizing current as well as the magnetizing curv…

Direct Derivation of Corrective Terms in SDE Through Nonlinear Transformation on Fokker–Planck Equation

2004

This paper examines the problem of probabilistic characterization of nonlinear systems driven by normal and Poissonian white noise. By means of classical nonlinear transformation the stochastic differential equation driven by external input is transformed into a parametric-type stochastic differential equation. Such equations are commonly handled with Ito-type stochastic differential equations and Ito's rule is used to find the response statistics. Here a different approach is proposed, which mainly consists in transforming the Fokker–Planck equation for the original system driven by external input, in the transformed probability density function of the new state variable. It will be shown …
