Optical properties of soot have been investigated with and without potassium chloride (KCl) salt added to the soot formation process in a premixed ethylene/air flame. A strong decrease in optical absorption efficiency of the soot was observed with increasing amounts of KCl added to the fuel based on the method of fluence curve analysis using laser-induced incandescence (LII). To understand the rea

The advent of foundation models signals a new era in artificial intelligence. The Segment Anything Model (SAM) is the first foundation model for image segmentation. In this study, we evaluate SAM's ability to segment features from eye images recorded in virtual reality setups. The increasing requirement for annotated eye-image datasets presents a significant opportunity for SAM to redefine the lan

Background: Health-related quality of life and patient-related outcome measures for patients with cancer have gained increased interest over the last decade. However, few prospective studies with longitudinal data evaluated health-related quality of life in patients with breast cancer. This study aimed to investigate how health-related quality of life changed from the time of diagnosis to 1 year a

This paper addresses the attitude synchronization problem of multiple rigid body agents in SO(3) with directed and switching interconnection topologies. Using the axis-angle representation of the orientation, a distributed controller based on differences between the orientations of agents in a global frame is proposed. In the case of the balanced interconnection graph, the attitude synchronization

BACKGROUND: Little is known about risks of hypertensive disorders of pregnancy in both first-and second-generation immigrant women in Europe and other Western countries; such knowledge may help elucidate the influence of genetic versus social factors on such risks. We aimed to study both first-and second-generation immigrant women for the presence of all types of hypertension (preexisting hyperten

Recent years’ publications have shown how valuable information can be in the integrity management of civil structures. Monitoring systems increase the knowledge about the structural state, improving the prioritization of the interventions, and the selection of optimal maintenance strategy and thereby allowing for budget optimization and risk minimization. This paper investigates the effect of mult

We formulate a version of the low-scale Majoron model equipped with an inverse seesaw mechanism featuring lepton-number preserving dimension-6 operators in the scalar potential. Contrary to its dimension-4 counterpart, we find that the model can simultaneously provide light and ultralight Majorons, neutrino masses and their mixing, while featuring strong first-order cosmological phase transitions

Disease recurrence in surgically treated lung adenocarcinoma (AC) remains high. New approaches for risk stratification beyond tumor stage are needed. Gene expression-based AC subtypes such as the Cancer Genome Atlas Network (TCGA) terminal-respiratory unit (TRU), proximal-inflammatory (PI) and proximal-proliferative (PP) subtypes have been associated with prognosis, but show methodological limitat

The Emergency Management sector in Denmark consists of 24 Municipal Fire and Rescue Services (MFRSs) responsible for providing a justifiable response to prevent, limit, and redress personal injury and damage to property and the environment arising from accidents and disasters. This research investigates how the MFRSs throughout Denmark define and direct the prevention and response parameters of qu

Strengthening of masonry walls is a means to improve the energy performance of modern external masonry walls without further increasing their total thickness. The present paper evaluates the feasibility - here refer-ring to ease-of-application and structural performance - of several techniques aimed at strengthening mason-ry walls subjected to eccentric axial loading. Four full scale walls made of

Animals across phyla can detect early cues of infection in conspecifics, thereby reducing risk of contamination. It is unknown, however, if humans can detect cues of sickness in people belonging to communities with whom they have limited or no experience. To test this, we presented Western faces photographed two hours after the experimental induction of an acute immune response to one Western and

This paper presents stability theory of adaptive systems using an extension of the Yakubovich-Kalman-Popov (YKP) lemma. Such stability analysis is relevant for observer-based adaptive feedback control systems. Relaxation of the controllability and observability conditions imposed in the YKP lemma can be made for a class of adaptive systems described by a linear time-invariant (LTI) system with ada

Connecting the complementary facilities MAX IV & ESS with DESY & European X-FEL creates synergy and a globally unique infrastructure region with fantastic opportunities for innovation and research not least in Life Science. Through Hanseatic League of Science (HALOS) the Life Science research and innovation ecosystems is given a joint platform to take advantage of the facilities and a tool

The objective is to study the effect of high voltage pulses on living cells to find the most effective combination of physical parameters to be used in tumour therapy. Four parameters that affect the cell survival are the pulse shape, electric field strength, pulse length and the number of pulses and their cell killing effect were investigated in this work. High voltage square wave or exponentiall

CONTEXT: Once islet autoantibody-positive individuals are identified, predicting which individuals are at highest risk for type 1 diabetes (T1D) is important. A metabolic risk score derived from 2-hour oral glucose tolerance test (OGTT) data, the Diabetes Prevention Trial-Type 1 risk score (DPTRS), can accurately predict T1D. However, 2-hour OGTTs are time-consuming and costly. OBJECTIVE: We aimed

Background: More women in reproductive ages are entering occupations where exposure to whole body vibrations (WBV) is common (e.g. in transportation and construction). Previous studies based on self-assessed exposure suggest increased risks of adverse birth outcomes, but it is unclear at what exposure levels and if the current exposure guidelines are appropriate during pregnancy. Objectives: To in

Structural monitoring (e.g. structural measurement and damage detection) and inspections have been widely applied as part of structural maintenance. However, the potential of using the obtained information is not yet fully exploited to update the structural reliability and support the maintenance and operation strategy. This paper describes the foundations, limitations, and characteristics of meas

In this study, global wave climates for present and future climates are simulated by the WAM model, based on wind climate data from the JMA/MRI-AGCM3.2 climate change projection. This study is based on two 6-hourly wind data sets, covering two periods of 1979-2003 (present climate) and 2075-2099 (future climate). These wind data are used to run the WAM model for generating output of wave character

Background: Women who deliver pre-term have been reported to have increased future risks of cardiometabolic disorders. However, their long-term risks of ischemic heart disease (IHD) and whether such risks are due to shared familial factors are unclear. A better understanding of these risks may help improve long-term clinical follow-up and interventions to prevent IHD in women. Objectives: The purp

OBJECTIVE: The authors examined the association between alcohol use disorder (AUD) and risk of suicide, before and after accounting for psychiatric comorbidity, and assessed the extent to which the observed association is due to a potentially causal mechanism or genetic and familial environmental confounding factors that increase risk for both. METHODS: Longitudinal population-wide Swedish medical
