Every aspect of modern life is dominated by decision-making and the availability of data. We constantly access, process and evaluate data as we navigate complex and uncertain problem spaces. Communication and Information Technologies (ICTs) have developed to a point where it is possible for very large data sets, measured in Exabyte, to be stored across many servers and gathered by many different p
Purpose: The influence of allograft ischemic time (IT) on short- and long-term mortality remains under debate in lung transplantation (LTx). Due to a scarcity in donors, better understanding of IT might improve the outcome after LTx. Methods: Between January 1990 and June 2016; 307 patients underwent LTx at Lund university hospital, Sweden. The end-point used was death/Re-LTx assessed by Cox regre
The causes and extent of regional inequality in the process of economic growth are at the core of historical economic research. So far, much attention has been devoted to studying the role of industrialization in driving regional divergence. However, empirical studies on relatively unequal countries such as Italy and Spain show that inequality was already high at the outset of modern industrializa
Modern emerging technologies, such as additive manufacturing, bioprinting, and new material production, require novel metrology tools to probe fundamental high-speed dynamics happening in such systems. Here we demonstrate the application of the megahertz (MHz) European X-ray Free-Electron Laser (EuXFEL) to image the fast stochastic processes induced by a laser on water-filled capillaries with micr
Many nocturnal animals, including invertebrates such as scorpions and a variety of vertebrate species, including toadlets, flying squirrels, owls, and nightjars, emit bright fluorescence under ultraviolet light. However, the ecological significance of this unique coloration so attached to nocturnality remains obscure. Here, we used an intensively studied population of migratory red-necked nightjar
This paper proposes an interaction and safety-aware motion-planning method for an autonomous vehicle in uncertain multi-vehicle traffic environments. The method integrates the ability of the interaction-aware interacting multiple model Kalman filter (IAIMM-KF) to predict interactive multi-modal maneuvers of surrounding vehicles, and the advantage of model predictive control (MPC) in planning an op
The most common noise in geophysical data is probably interference from powerlines. This noise manifests itself as a sinusoidal signal oscillating at the fundamental 50 or 60 Hz frequency of the power grid and as harmonic components oscillating at integer multiples. Many different mitigation strategies, tailored for the specific geophysical method, have been developed to target powerline noise. On
Lead-free Sn(II) based, CsSn2Br5, perovskite nanocubes were synthesized using a modified hot-injection method by tuning the injection temperature and reaction conditions. The formation of Sn(IV) based, Cs2SnBr6, perovskite nanocrystals (PNCs) from CsSn2Br5 perovskite nanocubes was observed. X-ray diffraction measurements revealed that oxygen or water molecules in air gradually react with CsSn2Br5
Image processing provides tools for image enhancement and extraction of information from images. Modification of the colour table allows for amplification of the contrast in certain pixel-value intervals while the contrast is suppressed in other intervals. This can in turn be used to selectively enhance the displayed image in intervals of special importance to the current problem. One of the most
Antinuclei found in cosmic rays could provide a smoking gun signal for dark matter as this signal is virtually background free. The study of 3He cosmic rays requires the knowledge of their production, propagation in the galaxy and annihilation cross-section. While the former two have been already estimated with data-driven methods, there were no experimental data available for the 3He inelastic cr
Objective: This study evaluates whether food intake affects systolic and diastolic echocardiographic measurements in healthy seniors. Methods: Thirty healthy subjects 65–70 years of age were investigated with echocardiography, at fasting and then 30, 90, and 180 min after a meal. Results: After 30 min the biggest changes were seen in left ventricular wall stress and myocardial performance index wi
The ultrafast structural dynamics of water following inner-shell ionization is a crucial issue in high-energy radiation chemistry. We have exposed isolated water molecules to a short X-ray pulse from a free-electron laser and detected momenta of all produced ions in coincidence. By combining experimental results and theoretical modeling, we can image dissociation dynamics of individual molecules i
Limited knowledge of African historical inequality trajectories hampers our understanding of inequality outcomes today and leads to a major omission in debates about global inequality. Economies in colonial Africa were characterized by a process of export-oriented commercialization. We hypothesize that this process itself, the capital intensity of the commodities produced, and the relative importa
This paper presents annual estimates of total and per-capita GDP at 1910 prices for the regions of Imperial Austria from the origin of the Dual Monarchy (1867) to the eve of WWI (1913). The time paths of regional GDP are estimated from the yield of the tax on the transfer of real and financial property which is itself very highly correlated with the Schulze (2007) estimates of regional GDP for cen
Broadband circuit models for electric machines are effective means to understand, predict, and control the phenomenon of conducted Electromagnetic Interference (EMI) from immunity/susceptibility perspective. These models should cover the capacitive and inductive coupling behavior of the component along the frequency range of interest. Circuit models used under generic SPICE simulation softwares ar
We present an optimal adaptive controller that is used to regulate the chemical process of wood ash stabilization (WAS). The model parameters of the time-varying process dynamics are estimated using recursive least squares (RLS). At each batch an auto-tuning sequence produced with the controller disabled is carried through in order to obtain a good estimate of the process dynamics. After the auto-
The binocular field of vision differs widely in birds depending on ecological traits such as foraging. Owls (Strigiformes) have been considered to have a unique binocular field, but whether it is related to foraging has remained unknown. While taking into account allometry and phylogeny, we hypothesized that both daily activity cycle and diet determine the size and shape of the binocular field in
