Many migratory birds have changed their timing of arrival at breeding grounds in response to recent climate change. Understanding the adaptive value and the demographic consequences of these shifts are key challenges. To address these questions we extend previous models of phenological adaptation to climate change under territory competition to include feedback from population dynamics, winter sur
Laser-induced fluorescence imaging of the NH radical using excitation in the (0-0) and (1-0) vibrational bands of the A3Π-X3Σ– electronic transition is characterized in premixed NH3-air flames. Filtered detection for excitation of the (1-0) band is found to be beneficial for measurement conditions with a challenging background and/or interferences. Concentration evaluation for excitation in the (0
We propose a signal-to-noise criterion which predicts whether a feature of a given size and scattering strength, placed inside a larger object, can be retrieved with two common X-ray imaging techniques: coherent diffraction imaging and projection microscopy. This criterion, based on how efficiently these techniques detect the scattered photons and validated through simulations, shows in general th
We consider optimal precoder design for multi-user multiple-input multiple-output (MIMO) broadcasting channels in single-carrier (SC) systems. Instead of linear detection, we assume that advanced non-linear channel shortening (CS) detectors are utilized at the receivers. Such a scenario is challenging for precoder design as the uplink-downlink duality is inapplicable. The target of our linear prec
In fMRI studies with evoked activity, brain activity is detected by voxel-wise GLM tting, followed by statistical hypothesis testing. Statistical parametric mapping (SPM), one of the most popular classical methods, relies upon Gaussian smoothing to deal with the multiple-comparison correction. As an alternative, we have recently introduced a graph-based framework for fMRI brain activation mapping
Purpose The purpose is to develop a framework for measuring the S&OP process performance. Design/methodology/approach The method used is a multiple case study of five companies from different industries based on data from twelve structured interviews. Findings The main result is a framework to measure the S&OP process. It includes concrete suggestions for organizations when developing me
The laminar burning velocity is a fundamental property of combustiblemixtures important for kinetic model validation as well as for practicalapplications. Many efforts are directed towards its accurate determination.The heat flux method is one of the commonly recognized methodsfor measuring laminar burning velocity, however, the information on theaccuracy of the method is scattered in the literatu
Using ultralow-power wake-up receivers (WRxs) can reduce idle listening energy cost in wireless sensor networks with low traffic intensity. This has led to many WRx analog front-end (AFE) designs presented in literature, with a large variety of trade-offs between the sensitivity, the data rate, and the power consumption. Energy consumed during wake-up in a network depends on many parameters and wi
Mixed cultures of a heterotrophic nitrifier/aerobic denitrifier, Thiosphaera pantotropha, and an autotrophic nitrifier, Nitrosomonas europaea, were grown in chemostats under dual ammonia-and acetate limitation. Because of simultaneous nitrification and denitrification by T. pantotropha, the activity of the cultures was evaluated from nitrogen balances as complete as possible. Under most conditions
The FragMAX facility at MAX IV Laboratory is a state-of-the-art platform for crystallographic fragment screening, designed to support structure-based drug and chemical tool compound discovery. This facility offers a comprehensive workflow, from high-throughput crystal preparation and automated diffraction data collection at the BioMAX beamline to advanced data processing and analysis using custom
Clustering samples based on similarity remains a significant challenge, especially when the goal is to accurately capture the underlying data clusters of complex arbitrary shapes. Existing density-based clustering techniques are known to be best suited for capturing arbitrarily shaped clusters. However, a key limitation of these methods is the difficulty in automatically finding the optimal set of
The expected monetary value is a criterion for assessing the Value of Structural Health Monitoring (SHM) and supporting the associated decision making. Its calculation can be challenging, as it requires considering all possible outcomes of the SHM system. In this article a new approach to cost-benefit analysis for SHM systems is proposed, which is based on an estimate of the capability of the SHM
Accurate imputation is essential for the reliabilityand success of downstream tasks. Recently, diffusion models haveattracted great attention in this field. However, these models neglect the latent distribution in a lower-dimensional space derivedfrom the observed data, which limits the generative capacityof the diffusion model. Additionally, dealing with the originalmissing data without labels be
Portal hypertension, a life-threatening complication of cirrhosis,is largely triggered by increased intrahepatic vascular resistance.Fibrosis, regenerative nodule formation, intrahepatic angiogenisis and sinusoidalremodelling are classical mechanisms that account for increasedintrahepatic vascular resistance in cirrhosis. Our study leverages highresolution3D synchrotron radiation-based microtomogr
