Attosecond pulses allow for imaging of very fast processes, like electron dynamics. Stockman et al. suggested to use these pulses in connection with a Photoemission electron microscope (PEEM) to study the ultrafast dynamics of plasmons (Stockman et al. Nat Photonics 1:539–544, 2007). For efficient plasmon studies, the repetition rate of the attosecond pulses used needs to be higher than a few kHz
Aim: Childhood cancer patients are subjected to recurring painful medical procedures. In low- and middle-income countries (LMIC), where the majority of the world's childhood cancer patients live, pain management is often unsatisfactory due to limited resources. This study aimed to evaluate the possibility of conducting a preprocedural preparation for lumbar punctures (LPs) at a pediatric oncology
Aim: “Early” withdrawal of life support therapies (eWLST) within the first 3 calendar days after resuscitation from cardiac arrest (CA) is discouraged. We evaluated a prospective multicenter registry of patients admitted to hospitals after resuscitation from CA to determine predictors of eWLST and estimate its impact on outcomes. Methods: CA survivors enrolled from 2012–2017 in the International C
Contamination or damage to X-ray optics is becoming increasingly problematic for beamlines at 3rd and 4th generation storage-rings and FEL sources. Carbon contamination, induced by ultra-intense photon-beams, can cause a major loss in flux, focusing power, and specific absorptions which are detrimental to spectroscopy. For new light sources, with higher coherence, intensity, and repetition rates,
In June 2024, the community of Roxborough Park, Colorado conducted a wildfire evacuation exercise (or drill for short) that was observed by a team of researchers. This collaborative effort involved residents, community organizers, first responders, emergency managers, and researchers. The drill aimed to test and refine evacuation protocols, communication strategies, and coordination among various
BACKGROUND: Changes in Ischemic White matter hyperintensities volume (WMH) on MRI over time are associated with cognitive decline. We investigated whether changes in WMH volume over time exhibit WMH-normalized volume threshold effects on declining cognitive performance and whether these effects on cognition differ between deep white matter hyperintensities (DWMH) and periventricular white matter h
PURPOSE: To examine sex differences in health-related quality of life (HRQoL) among patients surgically treated for renal cell carcinoma (RCC) in Sweden, utilizing data from the National Swedish Kidney Cancer Register (NSKCR).METHODS: In this study of 4658 surgically treated RCC patients, data on HRQoL, clinical, demographic, and socioeconomic characteristics were retrieved from the NSKCR for pati
This study evaluated the adaptation of relapse prevention treatment, originally for substance use, to address problematic gaming in children and adolescents. The goal was to understand the feasibility of this treatment in child and adolescent mental health services from the clinicians’ perspective. Six clinicians, four women and two men aged 37–47 with 4–20 years of work experience, were interview
In the present study, water-oil flow patterns and slug hydrodynamics were experimentally studied in square glass microchannels with various hydraulic diameters (Dh = 600 µm, 400 µm, 200 µm). The aqueous phase is the continuous phase while the organic phase is the dispersed phase. The ranges of flow rates of the continuous phase and the dispersed phase are 0-200 ml/h and 0-12 ml/h, 0-120 ml/h and 0
Purpose: To describe how patients with acute/subacute back pain and/or neck pain experienced a workplace intervention, conducted as a structured workplace dialogue (convergence dialogue meeting, CDM) within physiotherapy practice in primary care. Materials and methods: Semi-structured interviews were performed with 10 patients who took part in the CDM. Qualitative content analysis was applied to t
This article examines the historical genesis, nature, features and international legal status of the Institute representation at the UN, both on the territory of the member states and of the member states to the UN. An attempt was made to reveal the status and characteristics of the offices of both the UN and its specialized agencies. On the basis of the analysis, proposals were made to strengthen
Meso-tetra(hydroxyphenyl)chlorin (mTHPC) (international generic name Temoporfin) is a potent photosensitizer used for photodynamic therapy (PDT). In this study the pharmacokinetics of a systemically administered novel lipid formulation of Temoporfin in a murine tumor model has been investigated. Fluorescence spectroscopy measurements were performed at several time intervals following drug administ
We analyse recent experiments on momentum shearing interferometry of electron wave packets1,2 by using an optical analogy with shearing interferometry for optical waves. This analogy offers a convenient point of view to discuss the capabilities and difficulties of this technique used to access the phase of electron wave packets.
Wireless capsule endoscopy (WCE) is the prime diagnostic modality for the small-bowel. It consists in a swallowable color camera that enables the visual detection and assessment of abnormalities, without patient discomfort. The localization of the capsule is currently performed in the 3D abdominal space using radiofrequency (RF) triangulation. However, this approach does not provide sufficient inf
We propose a novel, real-time algorithm for recoloring images to improve the experience for a color vision deficient observer. The output is temporally stable and preserves luminance, the most important visual cue. It runs in 0.2 ms per frame on a GPU.
The paper presents digital nomads’ experiences about the support of digital technologies in relation to social isolation. Despite the abundant access to digital technologies for organizational cooperative purposes, the challenge of social isolation constitutes one of the central concerns in nomadicity practices, affecting employees’ choice of working arrangements. To gain further knowledge on the
