Inspired by the flow description of su(N) colour calculations, we recently showed how to simplify the spinor-helicity formalism (at the algebra level two copies of complexified su(2)) by treating each Weyl spinor as part of a flow line with definite chirality and momentum. This formalism, dubbed the chirality-flow formalism, eliminates all non-trivial algebra from tree-level spinor-helicity calcul
A search for the K+ → π+X decay, where X is a long-lived feebly interacting particle, is performed through an interpretation of the K+ → π+νν¯ analysis of data collected in 2017 by the NA62 experiment at CERN. Two ranges of X masses, 0–110 MeV/c2 and 154–260 MeV/c2, and lifetimes above 100 ps are considered. The limits set on the branching ratio, BR(K+ → π+X), are competitive with previously repor
The luminosity monitor LUCID (LUminosity Cherenkov Integrating Detector) employed in the ATLAS experiment at the LHC had to be upgraded for the second run of LHC (Run 2) that started in spring 2015. The increased energy of the proton beams and the higher luminosity implied that the Photomultipliers of the original LUCID detector had to be replaced for Run 2 to cope with the more demanding conditio
Background: Electrocardiogram-derived grades of ischemia at the time of patient presentation with acute myocardial infarction have proved useful in predicting the salvageability by reperfusion therapy, final infarct size, severity of left ventricular dysfunction, and short- and long-term prognosis. Subjects and Methods: The Sclarovsky-Birnbaum Ischemia Grading System based on the relation between
Often in clinical practice, a diagnosis of alcohol dependence or abuse does not provide enough information to establish an adequate treatment plan. Hence, multidimensional instruments have been constructed better to describe the extent and character of a patient's alcohol problem. The purpose of the current article is to present the AVI-R2, a self-report test that provides a standardized and diffe
In this talk we give an overview of the existing codes that aim for the automation of the subtraction terms in next-to-leading order calculations in perturbative QCD.
Purpose: Comorbidity indices are often used to measure comorbidities in register-based research. We aimed to adapt the Charlson comorbidity index (CCI) to a Swedish setting. Methods: Four versions of the CCI were compared and evaluated by disease-specific experts. Results: We created a cohesive coding system for CCI to 1) harmonize the content between different international classification of dise
We investigate robustness properties of the Generalized Proportional Allocation (GPA) policy that has been recently proposed for traffic signal control in urban networks. The GPA policy is fully decentralized, relies only on local information on the current congestion state, and requires no knowledge of the routing, the exogenous inflows, or the network structure. In previous work, we proved throu
The adoption of the International Convention on Civil Liability for Bunker Oil Pollution Damage 2001 plugs a gap in the otherwise comprehensive international liability and compensation regime for ship-source pollution. Although liability for bunkers pollution from tankers was partially regulated by other civil liability regimes, bunker spills pollution from other types of vessels was left uncovere
Ekonomiska kriser genomgår i regel tre faser, en akut fas, en vårdfas samt en rehabili-teringsfas. Thailand befinner sig nu i efterdyningarna av den tredje fasen och frågan är hur återhämtningen från den ekonomiska krisen 1997 med facit i hand egentligen har gått och om man hade kunnat påverka utvecklingen genom att handla på ett annorlun-da sätt. Förtroendet för en ekonomi kan mätas på flera olik
The proportion of meals the Europeans eat outside their home steadily increases. We take coffee breaks at work, eat lunch in the office canteen, we order take-away, we go to cafés or pubs to spend time with our friends, we easily grab a snack in vending machines and we eat on airplanes and trains to just mention a few examples. Eating out is nowadays more of an everyday activity than a luxury even
Background/Objectives: Older patients are more susceptible to the process of understanding and retrieving information. To provide adequate preoperative information, reduce their vulnerability and anxiety, and thereby facilitate pre-, intra-, and postoperative care, the adoption of new information technologies is essential. This study aimed to explore elderly patients' experiences and perceptions o
Normally, the measurement limit for luminescence analysis of quartz is 50-70 ka with the most widely used single aliquot regeneration (SAR) protocol, consequently, the dating of MIS 3 and MIS 4 samples or older is problematic using quartz. However, recent studies propose that the sensitivity-corrected multiple aliquot regenerative dose (SMAR) measurement technique has the potential to extend the d
The introduction of “water-in-salt” electrolyte (WiSE) concept opens a new horizon to aqueous electrochemistry that is benefited from the formation of a solid-electrolyte interphase (SEI). However, such SEI still faces multiple challenges, including dissolution, mechanical damaging, and incessant reforming, which result in poor cycling stability. Here, we report a polymeric additive, polyacrylamid
Multi-hazard events, though infrequent and rare, are responsible for a substantial portion of global economic losses. This book chapter investigates the complexities of multi-hazard events and explores the design challenges and methodologies in multi-hazard risk assessment and structural resilience for wooden structures. Special attention is given to the interaction between earthquakes, fires, and
In this 5th version of the European LeukemiaNet guidance for adult patients, there are important changes in several areas of management based on evidence available since 2020, including the World Health Organisation’s reclassification of CML as a biphasic disease. Previous advice to switch the tyrosine kinase inhibitor (TKI) on failure of molecular milestones, is modified to better account for ind
The AU Microscopii planetary system is only 24 Myr old, and its geometry may provide clues about the early dynamical history of planetary systems. Here, we present the first measurement of the Rossiter–McLaughlin effect for the warm sub-Neptune AU Mic c, using two transits observed simultaneously with the European Southern Observatory’s (ESO’s) Very Large Telescope (VLT)/Echelle SPectrograph for R
The modelling of filtered chemical source terms remains a fundamental challenges for large eddy simulation (LES) of reacting flows, such as combustion. This study investigates various scale similarity models for predicting filtered reaction rates. The theoretical foundation of scale similarity models is reviewed, and several extensions and generalisations are proposed. These include the distinctio
This article analyses how a newly established set of actors – online brokerage firms (OBFs) – sought to popularise stock trading among the Swedish populace in the late 1990s. During this period, internet usage took off and stock markets surged rapidly up until the dotcom bubble burst in 2000. Sweden was at the forefront of both these international developments, and we analyse the intimate connecti
