Towards accurate measurement of methanol combustion emissions : Calibration and Insights for flame ionization detectors and Fourier transform infrared analyzers

Methanol is a promising renewable fuel that can be used to reduce the carbon intensity of internal combustion engines. In any combustion strategy with methanol, both unburned methanol and formaldehyde emissions are criteria pollutants that are potential drawbacks, so their accurate measurement is critical. The flame ionization detectors (FIDs) typically used in engine research to measure unburned

Family history of diabetes mellitus and risk of colorectal cancer : A nationwide cohort study

Aims: Studies have shown the association between personal history of diabetes mellitus (DM type 1/2) and risk of colorectal cancer (CRC). This study aims to find the association between the family history of diabetes and CRC risk. Methods: This large nationwide cohort study leveraged data from several Swedish nationwide registers (follow-up: 1964–2018) to compare the risk using standardized incide

Suicide and attempted suicide in gambling disorder - results from a nationwide case-control study

Background: Gambling disorder severely impacts the affected individual's daily life and is considered to be a major public health issue. Gambling disorder may be a risk factor for suicidal behavior, but matched case-control studies are few. This study aims to explore suicidal behavior, and risk factors for it, among patients with GD in comparison with age- and gender-matched controls. Methods: Thi

AI-driven analyzes of open-ended responses to assess outcomes of internet-based cognitive behavioral therapy (ICBT) in adolescents with anxiety and depression comorbidity

Objective: Although patients prefer describing their problems using words, mental health interventions are commonly evaluated using rating scales. Fortunately, recent advances in natural language processing (i.e., AI-methods) yield new opportunities to quantify people's own mental health descriptions. Our aim was to explore whether responses to open-ended questions, quantified using AI, provide ad

Are there minimal exceptional aGUTs from stable 5D orbifolds?

In analysing five dimensional orbifolds with exceptional gauge groups, we seek to find stable vacua configurations which satisfy the minimal requirements for asymptotic grand unified models. In this respect we show that no minimal asymptotic grand unified theory can be built. Our results point towards non-minimal models based on E6: one featuring supersymmetry, and the other needing a modification

Learning in Practice: Actors-networks and sociotechnical approach to understanding the constitution of protection of pipelines against clandestine diversions in the oil and gas industry

In many countries, the oil and gas industry (OGI) faces a sociotechnical problem related to illegal tapping, a complex phenomenon involving stealing products from pipelines. This study analyses the network constitution to understand and tackle this phenomenon, called ”clandestine diversion” (CD), which is the theft of oil and its derivatives products through illegal tappings of onshore pipelin

Cardiac rehabilitation and physical activity decrease the risk of stroke after acute myocardial infarction : A nationwide cohort study in Sweden

Background: Stroke and acute myocardial infarction (AMI) rank among the leading causes of mortality. Physical activity and exercise are recommended as part of rehabilitation after AMI to prevent cardiovascular events, but the importance for stroke prevention has not been investigated using population-based data. Objectives: To determine associations between participation in exercise-based cardiac

Dark matter spiral arms in Milky Way-like halos

Context. The coupling between the dark matter (DM) halo and the stellar disc is a key factor in galactic evolution. While the interaction between structures like the Galactic bar and DM halos has been explored (e.g. slowing down of the bar due to dynamical friction), the effect of spiral arms on the DM halo distribution has received limited attention. Aims. We aim to detect and characterize the in

Unravelling the Genotype of the Apical Variant of Hypertrophic Cardiomyopathy in a Swedish Cohort

Background: Apical hypertrophic cardiomyopathy (ApHCM) is a distinct variant of hypertrophic cardiomyopathy (HCM). Few studies have focused on the genetic determinants of this subtype. We aimed to investigate the genetic basis of apical hypertrophy in a Swedish cohort. Methods–Results: Longitudinal data on 58 unrelated index patients with ApHCM from the Southeast healthcare region in Sweden from 2

Land Surface Energy Partitioning Dominates Dry-Season Water Availability Uncertainties in Earth System Models

Accurately characterizing dry-season water availability (Wd) is critical for projecting terrestrial carbon exchange and global water security. Wd is commonly calculated as the minimum value of precipitation minus evapotranspiration within each calendar year. However, Earth System Model (ESM) projected Wd contains substantial uncertainties and can disagree on even the sign. Based on a newly propose

Assessing carbon emission impacts of sponge city development : insights from runoff reduction analysis

This study aimed to quantify the impact of sponge city facilities on both runoff reduction and carbon emission mitigation, providing valuable insights for sustainable urban development. Using the Storm Water Management Model (SWMM) 5.2 in conjunction with carbon emission factor calculations, we comparatively evaluated the annual runoff reduction and carbon emission abatement potential of tradition

Addressing Challenges in Simulating Inter–Annual Variability of Gross Primary Production

A long-standing challenge in studying the global carbon cycle has been understanding the factors controlling inter–annual variation (IAV) of carbon fluxes, and improving their representations in existing biogeochemical models. Here, we compared an optimality-based model and a semi-empirical light use efficiency model to understand how current models can be improved to simulate IAV of gross primary

In-Flight Observation and Surface Oxidation Modification of Tin Oxide Nanoparticles for Gas Sensing Applications

Metal oxide nanoparticles are essential in various applications, and the synthesis through gas-phase generation methods offers a rapid and reliable pathway for nanoparticle production. Yet achieving precise control over their formation remains challenging due to the complex nature of oxidation processes. While bulk oxidation states can be assessed via off-line measurements, the dynamic nature of s

Magnetic resonance-derived hepatic uptake index improves the identification of patients at risk of severe post-hepatectomy liver failure

Background: Post-hepatectomy liver failure (PHLF) is a leading cause of mortality after major liver resection. Accurate preoperative risk assessment is essential, yet current methods have limitations. Gadoxetic acid-enhanced MRI (Gd-EOB MRI) enables both morphological and functional evaluation of the liver. The aim of this study was to evaluate the efficacy of the hepatic uptake index (HUI) obtain

The rise of artificial intelligence for cognitive behavioral therapy : A bibliometric overview

Recent years have seen a sharply rising interest in the scientific area dedicated to the study of the use of Artificial Intelligence (AI) for Cognitive Behavioral Therapy (CBT) research and applications (AI4CBT for brevity). Yet, little is known about how this interest is realized and hence the overall status, prospects, and possible challenges of AI4CBT as a field (e.g. breadth of the field, key

Why Do Judgments on Different Person-Descriptive Attributes Correlate With One Another? A Conceptual Analysis With Relevance for Most Psychometric Research

Patterns of correlations among judgments of targets on different attributes are the basis for common psychometric procedures such as factor analysis and network modeling. The outcomes of such analyses may shape the images (i.e., theories) that we as scientists have of the phenomena that we study. However, key conceptual issues tend to be overlooked in these analyses, which is especially problemati

Coherently coupled carrier and phonon dynamics in elemental tellurium probed by extreme ultraviolet transient absorption

The narrow band-gap semiconductor elemental tellurium (Te) has a unique electronic structure due to strong spin-orbit splitting and a lack of inversion symmetry of its helical lattice. Using broadband extreme ultraviolet core-level transient absorption, we simultaneously measure the coherently coupled photoinduced carrier and lattice dynamics at the Te N4,5 edge initiated by a few-cycle NIR pulse.
