This thesis investigated the use of convolutional neural networks (CNNs) for image restoration of fingerprint images, focusing on the reconstruction from raw sensor images to denoised fingerprint images, suitable for matching. Fingerprint images from sensors often introduce noise and artifacts that inhibit the matching process. The goal was to develop a CNN-based approach capable of removing artif
Dalby Söderskog är belägen tio kilometer öster om Lund och har varit nationalpark sedan 1918. Växtligheten består av ädellövträd samt en rik vårflora av bland annat vitoch gulsippor och skånsk nunneört. Sommaren 1921 utfördes en taxering av skogen och en karta upprättades (figur 1). Kartan visar Söderskogens utbredning samt varje träd i densamma. Arbetet grundar sig på just denna karta men tar äveThe national park Dalby Söderskog is situated ten kilometres east of Lund and has been a national park since 1918. The vegetation consists of a deciduous forest of Oak, Beech, Elm, Ash and Alden. The forest is also famous thanks to its rich spring flora of among others Anemóne nemorósa, Anemóne ranunculoídes and Corýdalis bulbosa. In the summer of 1921 a map was drawn that shows the distribution o
Changes in the inlet morphology of choked coastal lagoons often restrict the water exchange with the sea, making them vulnerable to pollution events and eutrophication processes. In this study, the importance of tides for the water exchange was investigated in Mundaú Lagoon, which is a choked lagoon located in northeastern Brazil that has a very dynamic inlet and channel system. The analysis was c
The aim of this article is to develop the concept of time-space complexity as a way of discussing how territorial time-space production affects urban life and use. The discussion is based on a comparative study of opening hours in four centrally located European retail areas: Angers, Lisbon, Malmö and Porto. Following a comparative study of these areas, we discuss tendencies of temporal and spatia
Psoriasis is a type-1 T cell-mediated, chronic inflammatory disease. Since interleukin (IL)-12p70 promotes the development of type-1 T cells, we investigated whether psoriasis is associated with an increased production of this cyctokine by blood cells. Results revealed that the production of IL-12p70 by cells of psoriasis patients stimulated by 1 and 10 ng per mL, but not 100 ng per mL of lipopoly
OBJECTIVES: To describe the incidence of injury in the precompetition and competition periods of the Rio 2016 Summer Paralympic Games.METHODS: A total of 3657 athletes from 78 countries, representing 83.4% of all athletes at the Games, were monitored on the web-based injury and illness surveillance system over 51 198 athlete days during the Rio 2016 Summer Paralympic Games. Injury data were obtain
When primary tumor cells are grown in vitro, they are exposed to an environment that is vastly different from the tumor environment they originate from. The in vitro environment can lack the three-dimensional structure of the tumor, other cell types present within the tumor microenvironment, and important growth factors. Humanized mouse models allow researchers to study primary tumor cells in a mo
Current metabarcoding studies aiming to characterize microbial communities generally rely on the amplification and sequencing of relatively short DNA regions. For fungi, the internal transcribed spacer (ITS) region in the ribosomal RNA (rRNA) operon has been accepted as the formal fungal barcode. Despite an increasing number of fungal metabarcoding studies, the amplification efficiency of primers
Previous studies have shown that the injection of adipose stem cells and stromal vascular fraction(SVF) into the tunica albuginea (TA) during the inflammatory phase in a rat model of Peyronie’s disease(PD) prevented the development of TA fibrosis. Our aim was to investigate whether local injection of SVF can reduce established fibrosis in a rat model of chronic phase of PD. Eighteen-male 12-wk-old
We present chemical abundances for the elements carbon, sodium, and fluorine in 15 red giants of the globular cluster M4, as well as six red giants of the globular cluster ω Centauri. The chemical abundances were calculated in LTE via spectral synthesis. The spectra analyzed are high-resolution spectra obtained in the near-infrared region around 2.3 μm with the Phoenix spectrograph on the 8.1 m Ge
Background: The impact of a change in mitral regurgitation (MR) following TAVR is unknown. We studied the impact of baseline MR and early post-procedural change in MR on survival following TAVR. Methods: The SWEDEHEART registry included all TAVRs performed in Sweden. Patients were dichotomized into no/mild and moderate/severe MR groups. Vital status, echocardiographic data at baseline and within 7
Incidence of differentiated thyroid carcinoma (DTC) varies considerably between ethnic groups, with particularly high incidence rates in Pacific Islanders. DTC is one of the cancers with the highest familial risk suggesting a major role of genetic risk factors, but only few susceptibility loci were identified so far. In order to assess the contribution of known DTC susceptibility loci and to ident
BACKGROUND: Quinoa (Chenopodium quinoa Willd.) flour and processed traditional Peruvian quinoa breakfast foods were studied to evaluate the effect of extrusion and post-processing on protein properties, morphology and nutritional characteristics (amino acids and dietary fibers). RESULTS: The extrusion increased quinoa protein crosslinking and aggregation observed by size exclusion high-performance
Because biomass is a widely available, renewable resource, its utilisation for the production of energy has great potential for reducing CO2 emissions and thereby preventing global warming. In this mini-review the `state of the art' of several fermentation processes is discussed, starting with the most advanced process of ethanol production. This is followed by methane production, an established p
Peptides and proteins have evolved to self-assemble into supramolecular entities through a set of non-covalent interactions. Such structures and materials provide the functional basis of life. Crucially, biomolecular assembly processes can be highly sensitive to and modulated by environmental conditions, including temperature, light, ionic strength and pH, providing the inspiration for the develop
We show that algebraic proofs are hard to find: Given an unsatisfiable CNF formula F, it is NP-hard to find a refutation of F in the Nullstellensatz, Polynomial Calculus, or Sherali-Adams proof systems in time polynomial in the size of the shortest such refutation. Our work extends, and gives a simplified proof of, the recent breakthrough of Atserias and Müller (JACM 2020) that established an anal
Byggnaders energieffektivitet är ett fokusområde i arbetet med att minska klimatförändringarna, då byggnader står för cirka 40 procent av den totala energianvändningen i Europeiska unionen. En lösning som tillämpas för att minska byggnaders energibehov är att ständigt införa strängare byggregler. Följaktligen ökar betydelsen av precisa och effektiva simuleringar för att kunna beräkna byggnaders frAs most countries worldwide continue to mitigate climate change, one area of focus is a building's energy efficiency. Buildings currently account for approximately 40 per cent of the total energy use in the European Union. One solution for reducing the energy demand from buildings is by continually implementing more stringent building regulations. Consequently, the importance of accurate and effic
Introduction: Phenylketonuria (PKU) is a rare, treatable inborn error of metabolism with frequent neurological and neuropsychiatric complications, especially in undiagnosed or insufficiently treated individuals. Given the wide range of clinical presentations and the importance of treatment implications, we here delineate the neurological and neuropsychiatric symptom spectrum in a large cohort of p
Introduction: In dystonia, dopaminergic alterations are considered to be responsible for the motor symptoms. Recent attention for the highly prevalent non-motor symptoms suggest also a role for serotonin in the pathophysiology. In this study we investigated the dopaminergic, serotonergic and noradrenergic metabolism in blood samples of dystonia patients and its relation with (non-)motor manifestat
