Within a collaboration between MAX-lab and BESSY a one stage seeded HGHG-FEL has been set up at Maxlab. BESSY has built the undulator system consisting of a modulator, a radiator and an electromagnetic chicane. BESSY has also installed three types of diagnostic tools: optical fibres for a fast Cherenkov beam loss detection, optical fibres for absolute dose measurements via their radiation-induced
Background: The aim was to investigate the noise and bias properties of quantitative 177Lu-SPECT with respect to the number of projection angles, and the number of subsets and iterations in the OS-EM reconstruction, for different total acquisition times. Methods: Experimental SPECT acquisition of six spheres in a NEMA body phantom filled with 177Lu was performed, using medium-energy collimators an
Background: A single learning algorithm can produce deep learning-based image segmentation models that vary in performance purely due to random effects during training. This study assessed the effect of these random performance fluctuations on the reliability of standard methods of comparing segmentation models. Methods: The influence of random effects during training was assessed by running a sin
Non-revenue water due to pipe leakages presents a significant global challenge, impacting both the economy and environmental sustainability. The current approach to pipe management for water utilities in Sweden is mainly reactive; leaks are repaired when detected, sometimes with large costs if the leakage is extensive and critical. With this study, we want to focus on proactive pipe network manage
Cooperative driving is a promising paradigm to improve traffic efficiency and safety. In congested traffic scenarios, such cooperation allows for safe maneuvering and driving with small inter-vehicle spatial gaps. The vehicles involved coordinate their movements in real-time and continuously update each other about their maneuver execution status by means of Vehicle-to-Everything (V2X) communicati
In the multi-agent systems setting, this paper addresses continuous-time distributed synchronization of columns of rotation matrices. More precisely, k specific columns shall be synchronized and only the corresponding k columns of the relative rotations between the agents are assumed to be available for the control design. When one specific column is considered, the problem is equivalent to synchr
In this paper we study the output consensus problem for systems of agents with linear continuous, time invariant dynamics. We derive control laws with minimal energy that solves the problem, while using only relative information. Instead of considering a fixed communication topology for the agents, and derive the optimal control for that topology, we derive the optimal control law for any communic
We present a synchronized multisensory dataset for accurate and robust indoor localization: the Lund University Vision, Radio, and Audio (LuViRA) Dataset. The dataset includes color images, corresponding depth maps, inertial measurement unit (IMU) readings, channel response between a 5G massive multiple-input and multiple-output (MIMO) testbed and user equipment, audio recorded by 12 microphones,
Objectives: To report the long-term outcomes from a longitudinal psychosocial study that forms part of the ‘Identification of Men with a genetic predisposition to ProstAte Cancer: Targeted Screening in men at higher genetic risk and controls’ (IMPACT) study. The IMPACT study is a multi-national study of targeted prostate cancer (PrCa) screening in individuals with a known germline pathogenic varia
This chapter examines the evolving landscape of craft and its implications for market exchanges, focusing on the embedded relationships between craft producers and consumers. Craft, characterized as an ideology of work resisting the dominance of industrialization and mass production, has experienced several waves of revival throughout history. While contemporary craft hints at alternative social a
With the palliative care workforce shortage and changes in advance care planning reimbursement, many institutions are requesting that palliative care specialists provide serious illness communication training across their institution's workforce. Based on our experience training clinicians to use the Partners Serious Illness Conversation Guide, a structured guide to teach basic palliative care com
Thermal design of electric traction machines for high performance HEV drivetrains is a challenging task. Unlike conventional HEV traction machines, these machines are subject to continuous operation at or near their thermal limits during race-track driving, and so thermal management is of paramount importance to the mass and size of the machine. This article presents the main challenges related to
This paper forms part of a broader study on the design of an unconventional, high speed, switched reluctance machine (SRM), for automotive traction applications making use of soft magnetic composite (SMC) material. The aim is to have this machine operate at a fundamental frequency of up to 4 kHz. Another characteristic is that switched reluctance machines tend to be operated in deep saturation a l
In this study, we investigate how eco-social attitudes are interlinked with various modes of political action aimed at preventing environmental change and promoting social welfare. Using multiple correspondence analysis and cluster analysis, we explore the links between attitudes and political action, and associated socio-political characteristics, in the case of Sweden. Our results show a three-nIn this study, we investigate how eco-social attitudes are interlinked with various modes of political action aimed at preventing environmental change and promoting social welfare.

Background: Altered metabolism after liver surgery adds complexity topostoperative pain management. Opioids administered via intravenousPatient Controlled Analgesia (PCA) is one of the main alternatives forinitial pain management. Paracetamol is considered potentially dangerousafter liver surgery but used selectively. This study evaluates whether thereis a difference in patient outcome after hepat
Rapid and cost-effective retrieval of endogenous DNA from ancient specimens remains a limiting factor in palaeogenomic research. Many methods have been developed to increase ancient DNA yield, but modifications to existing protocols are often based on personal experience rather than systematic testing. Here, we present a new silica column-based extraction protocol, where optimizations were tested
