Atrial fibrillation is one of the most common supraventricular tachyarrhythmias. With an aging population and the increasing prevalence of atrial fibrillation worldwide, reliable and continuous monitoring systems that can capture respiratory information under varying medical conditions are needed. This study investigates and compares respiration signal extraction methods derived from electrocardio
We extend Mazo's concept of faster-than-Nyquist (FTN) signaling to pulse trains that modulate a bank of subcarriers, a method called two dimensional FTN signaling. The signal processing is similar to orthogonal frequency division multiplex (OFDM) transmission but the subchannels are not orthogonal. Despite nonorthogonal pulses and subcarriers, the method achieves the isolated-pulse error perfor
Abstract in UndeterminedThis paper describes a methodology for the optimization of portable parallel signal processing applications specified by dataflow programs. The use of dataflow as a programming model for signal processing applications targeting parallel platforms provides an important advantage versus the traditional sequential programming paradigm: the portability of parallelism. The paper
Popular Abstract in English Life on earth has evolved countless forms, beautiful shapes and colors as well as astonishingly complex systems. Remarkably, all living creatures consist of cells, which themselves are build from the same basic set of molecules, most importantly nucleic acids (RNA and DNA), lipids and proteins. The latter are large macromolecules that fulfill a vast number of tasks; theThe three-dimensional structure of protein is encoded in its amino acid sequence. Modern structure prediction algorithms make it possible to predict the structure of small proteins using sequence information alone. We used the Fold-and-Dock algorithm, which is part of the Rosetta macromolecular modeling suite, for de novo structure prediction of coiled-coil proteins. Members of this protein family
In this paper a multimodal optical-resolution photoacoustic and fluorescence microscope in frequency domain is presented. Photoacoustic waves and modulated fluorescence are generated in chromophores by using a modulated diode laser. The photoacoustic waves, recorded with a hydrophone, and the fluorescence signals, acquired with an avalanche photodiode, are simultaneously measured using a lock-in t
Philosophers’ search for the best way to explain human actions has led many to accept a core psychological model that can be supplemented by other forms of action explanation when needed. Rather than settling for this model –where everything ultimately hinges on psychologicalexplanation – this paper argues for a pluralistic view. It does not claim that the psychological view is
Previously, a method for computing binding free energies between different poses of a ligand bound to a protein using alchemical perturbation was developed. The methodology is to perturb the ligand into a smaller version, common to both poses, from which the difference in free energy between poses can be computed. Here, the method is further improved by finding low-error setups for the method, by

Bäst av allt att hela kursen totalt lyckades hitta rätt nivå, det är e
Can climate signals help investors make sharper moves in volatile commodity markets? This study explores how weather-related risk, specifically the El Niño-Southern Oscillation (ENSO), can be used to improve portfolio performance. We incorporate the Oceanic Niño Index (ONI) into a Random Forest forecasting model to capture the complex, non-linear effects of climate anomalies on commodity returns -
Radial motions of stars in nearby moving clusters are determined fromaccurate proper motions and trigonometric parallaxes, without any use ofspectroscopy. Assuming that cluster members share the same velocityvector (apart from a random dispersion), we apply a maximum-likelihoodmethod on astrometric data from Hipparcos to compute radial and spacevelocities (and their dispersions) in the Ursa Major,

As described, all program functionality is realized in separated modules. Inter-module communication is accomplished exclusively via a central container holding all image sets.The current version (1.2) encompasses the modules listed below. A couple of more experimental modules as a.o. CT -perfusion, image registration, and some code for ASL analysis are available upon request.Loading of a perfusio

Heart rate variability, commonly abbreviated as HRV, displays the variance between consecutive heartbeats. This variance occurs naturally but can change due to stress and problems with the cardiac system. HRV is therefore widely used for medical research. The goal of this thesis is to correctly classify two HRV signals where one is obtained at a resting state, the warm signal, while the cold signa
Abstract in Undetermined How signal diversity evolves under stabilizing selection in a pheromone-based mate recognition system is a conundrum. Female moths produce two major types of sex pheromones, i.e., long-chain acetates, alcohols and aldehydes (Type I) and polyenic hydrocarbons and epoxides (Type II), along different biosynthetic pathways.

Purpose: To assess whether grating-based X-ray dark-field imaging can increase the sensitivity of X-ray projection images in the diagnosis of pulmonary emphysema and allow for a more accurate assessment of emphysema distribution. Materials and Methods: Lungs from three mice with pulmonary emphysema and three healthy mice were imaged ex vivo using a laser-driven compact synchrotron X-ray source. Me

Classification of EMG signals is essential for diagnosis of motor neuron diseases like neuropathy and myopathy. Although a number of strategies have been implemented for classification, none of them are efficient enough to be implemented in clinical environment. In the present study, we use ensemble approach of support vector machines for classification of three classes (normal, myopathic and neur
