We present a light-storage experiment in a praseodymium-doped crystal where the light is mapped onto an inhomogeneously broadened optical transition shaped into an atomic frequency comb. After absorption of the light, the optical excitation is converted into a spin-wave excitation by a control pulse. A second control pulse reads the memory (on-demand) by reconverting the spin-wave excitation to an
The understanding of biochemical feedback mechanisms in the climate system is lacking knowledge in relation to bi-directional ammonia (NH3) exchange between natural ecosystems and the atmosphere. We therefore study the atmospheric NH3 fluxes during a 25-day period during autumn 2010 (21 October to 15 November) for the Danish beech forest Lille Bogeskov to address the hypothesis that NH3 emissions
There is a strong genetic predisposition towards abdominal aortic aneurysm (AAA), but it is unknown whether persons without AAA but with first-degree relatives who are AAA patients have a generalized dilating diathesis, defect arterial wall mechanics, or increased cardiovascular risk. The aim of the study was to investigate arterial diameters and wall mechanics at multiple arterial sites in these
Our aim was to compare the predictive accuracy of 4 different medial temporal lobe measurements for Alzheimer's disease (AD) in subjects with mild cognitive impairment (MCI). Manual hippocampal measurement, automated atlas-based hippocampal measurement, a visual rating scale (MTA-score), and lateral ventricle measurement were compared. Predictive accuracy for AD 2 years after baseline was assessed
BakgrundPalliativ vårdavdelning är en plats som ofta präglas av sorg, smärta och svåra beslut. För patienter och deras anhöriga kan det vara svårt att hitta utrymme för glädje och lättnad, och för vårdpersonalen innebär det dagliga mötet med döden en emotionell påfrestning. Sedan hösten 2023 har denpalliativa avdelningen i Lund fått oväntad men värdefull förstärkning: varannan vecka besöker två sj
In recent years, Predictive Digital Twins (PDT) have emerged as a potential tool to monitor and predict the behavior of dynamic systems, including nature-based solutions in natural coastal systems. Here, we test the potential of using a simple, coupled shoreline and beach-dune model as a base for a PDT. The models exchange sediment flux balance information at each time step and recalculate shoreli
PurposeThis study aims to assess the diffusion and integration of Circular Economy (CE) knowledge across academic disciplines, by examining how CE concepts spread within mainstream academic and disciplinary discourses.Design/Methodology/ApproachCE is conceptualized as a knowledge object, distinguishing between mainstream academic discourse (MAD) and mainstream disciplinary discourse (MDD). The res
BACKGROUND: Postoperative pancreatic fistula (POPF) is the most important complication after left pancreatectomy. Superiority of hand-sewn closure or stapler closure of pancreatic stump in terms of short-term outcomes is not established. The aim of this study was to compare short-term surgical outcomes between the 2 modalities after left pancreatectomy. STUDY DESIGN: An international, multicenter,
PURPOSE: To elucidate the pathophysiology of the carotid sinus reflex in a large cohort of patients with suspected reflex syncope.METHOD: We reviewed an electronic database of patients with suspected reflex syncope who underwent carotid sinus massage. The diagnostic protocol included both right and left massage, in supine and upright positions, followed by tilt testing.RESULTS: The cohort included
Denna uppsats behandlar ämnet religionsutövning i svenskt arbetsliv. Ämnet avhandlas dels utifrån perspektivet religionsfrihet som mänsklig rättighet, dels från perspektivet skydd och aktiva åtgärder mot diskriminering med religion som grund. Syftet är att göra en utredning i ämnet samt belysa frågan. Religionsfriheten stadgas i artikel 9 i Europakonventionen om de mänskliga rättigheterna och grun
Vid användning av hemliga tvångsmedel kan det framkomma uppgifter om annat brott än det för vilket det aktuella tvångsmedlet beslutats. Sådana uppgifter benämns överskottsinformation. I vad mån sådan information får utnyttjas är inte generellt reglerat i lag. Användning av överskottsinformation är ett aktuellt ämne och rättsläget är i dagsläget oklart. Uppsatsen syftar till att undersöka huruvida
The aim of this study is to examine whether there exists a right of humanitarian intervention in customary international law. The point of departure is the principle of non-use of force in customary international law. The International Court of Justice established in the Nicaragua Case that the principle of non-use of force not only is a jus cogens norm, but that it also has the basic identity of
Asyl- och migrationsfrågorna berörs ständigt i den offentliga debatten. Därutöver studeras och analyseras dessa frågor frekvent inom den akademiska världen. Ofta rör det sig om kritik och den kritik som förts fram i Sverige har bl.a. handlat om att det endast är ett fåtal av alla asylsökande som beviljas flyktingstatus i Sverige. Detta gäller såväl i jämförelse med det totala antalet som beviljas
This issue of the AILA Review focuses on transdisciplinarity as the key to developing shared languages in and across domains and professional settings. The relationship and collaboration between researchers and practitioners have long been discussed within and across applied sciences and theoretical disciplines, mainly in the framework of transdisciplinarity (see AILA Review 31, 2018, for a recent
Microorganisms are important sources of diverse intracellular and extracellular biopolymers havingdifferent functions such as serving as carbon and energy reserves, or as protective layers around the cells in theform of capsules and/or biofilms. They have also found use in foods, medicine and other industrial applications.Research on understanding the synthesis of several biopolymers as well as th
We have used angle-dependent soft x-ray absorption spectroscopy (XAS) at the O K edge and first-principles calculations to investigate the electronic structures of iridate-based superlattices (SrIrO3)m/(SrTiO3) (m=1, 2, 3, and ∞). We focus on the pre-edge Ir 5d t2g-O 2p orbital hybridization feature in the XAS spectra. By varying the measurement geometry relative to the incident photon polarizatio
Dynamic computer tomography (CT) is an emerging modality to analyze in-vivo joint kinematics at the bone level, but it requires manual bone segmentation and, in some instances, landmark identification. The objective of this study is to present an automated workflow for the assessment of three-dimensional in vivo joint kinematics from dynamic musculoskeletal CT images. The proposed method relies on
