The goal of this paper is to determine whether the photoplethysmography (PPG) can replace the ECG-based detection of heart rate turbulence. Using the PPG, classification of ventricular premature beats (VPBs) is accomplished with a linear classifier. The two conventional parameters turbulence onset and slope are studied together with a recently introduced parameter characterizing turbulence shape.

Popular Abstract in Swedish Personer med insulinbehandlad diabetes saknar, eller har kraftigt försämrad, kroppsegen förmåga att reglera blodsockernivån genom utsöndring av hormonet insulin, och måste därför ta flera injektioner insulin dagligen. De flesta injektioner tas i samband med måltid, och individen bestämmer normalt sina måltidsdoser utifrån aktuell blodsocker- och hälsostatus i kombinatioDiabetes is a disease characterized by insufficient capacity to regulate the blood glucose level. In insulin-dependent diabetes, multiple daily injections of insulin have to be administered. In-between scheduled visits to the care provider, the patient has to manage the glucose control independently. Insulin dosing is a non-trivial task and many patients find it difficult. This is reflected in the

Heavy-flavor hadrons, containing charm and bottom quarks, serve as a tool available for the characterization of the hot and dense strongly interacting Quark Gluon Plasma state of matter, produced in heavy-ion collisions. As a benchmark for heavy-ion collision measurements, proton-proton collisions are also studied. This thesis reports on the analysis of proton-proton collisions, reconstructed with

This thesis examines the relationship between experts and democracy in a specific case, the project of establishing a tramcar route from the central station in Lund to the northeast part of the city. The theoretical approach stems from the concept of networks and potential clashes in the relation between experts and democratic values. An examination has been done of 25 documents concerning the inv

Employee surveys are common tools for management to measure the attitudes of employees (Wiley, 2010). Due to globalization it also becomes more common that companies consist of different cultural compositions. Culture is a phenomenon that helps explain how people interpret their environment and can exist on a number of different levels (Hofstede &Hofstede, 2005). The study intended to examine

This thesis explores the simplifications the chirality-flow formalism brings the calculations of scattering amplitudes in massless QED. We explain Feynman diagrams and chirality- flow diagrams to emphasize how the calculations of scattering amplitudes differ. It is studied how applying the chirality-flow formalism simplifies the calculations. The work focuses on calculations with and without exter

The following research paper examines the impact of varying environmental regulation stringency on the landscape of green technological innovation in the maritime industry from 2006-2020. Additionally, the paper explores the potential indirect effect of these innovations, induced by stringency levels, on industry competitiveness. The research is grounded in a theoretical framework primarily drawin

Ulceration of primary melanomas is associated with poor prognosis yet is reported to predict benefit from adjuvant interferon. To better understand the biological processes involved, clinicopathological factors associated with ulceration were determined in 1804 patients. From this cohort, 348 primary tumor blocks were sampled to generate gene expression data using a 502-gene cancer panel and 195 b

Atmospheric aerosol particles serving as cloud condensation nuclei (CCN) are key elements of the hydrological cycle and climate. We have measured and characterized CCN at water vapor supersaturations in the range of S=0.10-0.82% in pristine tropical rainforest air during the AMAZE-08 campaign in central Amazonia. The effective hygroscopicity parameters describing the influence of chemical composit

Lund Municipality, just like many other municipalities, has recurring problems with rutting at their bus stops. There is a notable problem in Lund though and the rutting occurs regardless of whether the stops are placed at high, medium or low-volume roads. In this thesis, eleven of the most vulnerable coatings in Lund Municipality were investigated. This thesis is written in collaboration with roa

Perception of risks and related costs associated with energy crop cultivation pose a barrier to expansion of production, and therefore economies-of-scale are not achieved and investments in new infrastructure harder to justify. In this study, the risk perceptions for agro-biofuel production in Sweden, France and Finland are delineated and a new contractual arrangement to reduce such risk perceptio

Climate change has affected the extreme weather throughout the world. Studies have shown an increase of the extreme precipitation in Gothenburg, Sweden. At the same time, space limitations and cost considerations prevent the development of an optimized drainage system. Designing a stormwater system for an extreme rainfall is impossible due the high cost. In addition, the lack of space limits the a

Background: Insulin is a therapeutic protein that is widely used for the treatment of diabetes. Its biological function was discovered more than 80 years ago and it has since then been characterized extensively. Crystallization of the insulin molecule has always been a key activity since the protein is often administered by subcutaneous injections of crystalline insulin formulations. Over the year

The Fourier transform gas-phase IR spectrum of isoxazole, C3H3NO, between 550 and 1700 cm(-1) was measured with a resolution of ca. 0.003 cm(-1). Ten fundamental bands in the region 800-1700 cm(-1) have been analyzed by the Watson Hamiltonian model to yield upper state spectroscopic constants. A number of local resonances have been identified in the bands and explained qualitatively, and the unobs
