Animals use vision over a wide range of light intensities, from dim starlight to bright sunshine. For animals active in very dim light the visual system is challenged by several sources of visual noise. Adaptations in the eyes, as well as in the neural circuitry, have evolved to suppress the noise and enhance the visual signal, thereby improving vision in dim light. Among neural adaptations, spati

Popular Abstract in Swedish Ärftliga näthinnesjukdomar med tidig debut Elektrofysiologiska och genetiska studier Ärftliga näthinnesjukdomar är den vanligaste orsaken till allvarligt synhandikapp hos unga människor i dagens Sverige. De flesta av dessa sjukdomar kan ännu inte behandlas, men vi har under de senaste åren fått allt större insikt i de bakomliggande sjukdomsmekanismerna, tack vare att Hereditary retinal degenerations are the most frequent reason for severe visual handicap among young people in Scandinavia today. In the six papers included in this thesis the phenotypic expressions, with emphasis on the electrophysiological findings, of five different juvenile hereditary retinal degenerations are described. The diagnoses have been confirmed by genetic analysis. The retinal disord
Popular Abstract in Swedish Personer som arbetar med joniserande strålning inom t.ex. sjukvård, kärnteknik och forskning använder så kallade dosimetrar för att registrera hur mycket joniserande strålning (vilken stråldos) personen blivit utsatt för under ett arbetspass eller en arbetsmånad. Den stråldos som en dosimeter mäter ger ett mått på risken för eventuella sena hälsoeffekter i form av en ökIn the event of a radiation accident, it is crucial to make rapid estimates of the absorbed dose received by both emergency workers, so-called first responders, and members of the public. Today, only personnel in rescue teams responding to nuclear emergencies have access to individual dosemeters. To make accurate assessments of the radiological consequences of an emergency situation, methods of re
This thesis aims to examine the development of health trends in Sweden, since it is argued that they will prevail and even become more extreme in the near future. Supermarkets will have to understand the impact of those health trends on consumer behaviour and therefore are required to comprehend the sociological, cultural and psychological factors behind these. It is proclaimed that the current he

Some seabirds we encounter only fleetingly, as they fly by as we walk along the beach, or perhaps meet far out at sea when we take a boat trip. Others though we are more familiar with, such as the ‘seagulls’ that many will not even turn their head to appreciate. Yet, all seabirds have remarkable stories to tell, and we are fortunate now to live at a time where we can follow individual birds as theMost seabirds breed colonially, at which time they make central-place foraging trips. Parents must collect food both for themselves and for egg production/chick-rearing. How should they forage? I followed five species across two sites in Sweden in the Baltic Sea using GPS and time-depth recorder (TDR) devices, giving information on both flight and diving activity. I use a movement ecology approach
In this rapid era of technology, speed of communication has become an important factor. To overcome this challenge, 5G/NR technology is being explored. One of the ways of doing this is by using the so called millimeter wave spectrum. In order to make usage of the mmWave spectrum, due to the high path loss it introduces, the beamforming technique is adopted. Beamforming is a method used in high fre
Internet of Things (IoT) is a network constituted by uniquely identifiable commodity objects or devices equipped with some sensing system. To achieve high data rates required for IoT devices, a modern wireless communication system, known as Advanced Antenna Systems(AAS), leads to significant improvement, by increasing not only the data rate but also spectrum efficiency and the channel capacity.

The integration of high-precision cellular localization and machine learning (ML) is considered a cornerstone technique in future cellular navigation systems, offering unparalleled accuracy and functionality. This study focuses on localization based on uplink channel measurements in a fifth-generation (5G) new radio (NR) system.

Slowed adaptation of the QT interval to sudden abrupt heart rate (HR) changes has been identified as a marker of ventricular arrhythmic risk. However, abrupt HR changes are difficult to induce in patients. Quantifying the QT adaptation time in gradual HR changes, as observed in ECGs recording during an exercise stress test, has been recently proposed. The time lag between the QT series and an inst
Eye tracking studies suggest that refixations-fixations to locations previously visited-serve to recover information lost or missed during earlier exploration of a visual scene. These studies have largely ignored the role of precursor fixations-previous fixations on locations the eyes return to later. We consider the possibility that preparations to return later are already made during precursor f
Previous studies have shown that measurements of beluga whale (Delphinapterus leucas) and bottlenose dolphin (Tur-siops truncatus) echolocation signals at off-axis angles may be well modeled using a Gaussian bell function or a chirped Gaussian function as envelope. In this paper, we apply a novel technique, the matched window reassignment, for investigation of a range of models of dolphin echoloca
Sound and radio can be used to estimate the distance between a transmitter and a sender by correlating the emitted and received signal. Alternatively by correlating two received signals it is possible to estimate distance difference. Such methods can be divided into methods that are robust to noise and reverberation, but give limited precision and sub-sample refinements that are sensitive to noiseSound and radio can be used to estimate the distance between a transmitter and a sender by correlating the emitted and received signal.

ECG is susceptible to parasitic myopulses due to the overlapping frequency bandwidth of ECG and EMG. EMG signal has a bandwidth of about 20-500 Hz and overlaps with the ECG frequency range. i.e. 0.05-150 Hz. These interferences occur due to movement of muscles and respiratory actions during ECG recording. Removal of EMG noise from ECG is an important criterion for proper analysis of the signal. In
The kinetics of the buildup and decay of photoinduced birefringence was examined in a series of host-guest systems: azobenzene-containing crown ethers, differing in the size of the crowns, dissolved in a poly (methyl methacrylate) matrix. In all samples, the kinetics of the buildup of the birefringence was reasonably described by a sum of two exponential functions, the time constants being inverse
