Inland water CO2 emissions are a critical component of the global carbon cycle, yet their magnitude and long-term response to climate change remain poorly constrained, primarily because of uncertainties in the air–water CO2 concentration gradient. This knowledge gap is particularly pronounced on the Tibetan Plateau, where thin air and exceptional climate sensitivity complicate accurate quantificat
Cooling clothing is a personal cooling system that only cools the microclimate around an individual, alleviating heat stress. This study used a progressive heat stress protocol (PHSP) to evaluate the cooling effectiveness of a liquid cooling vest (LCV), a type of cooling clothing. Through the PHSP, the upper-limit thermal environment for the physiological prescriptive zone was determined for both
This article is an introduction to a special issue of the journal ‘Interface Focus’ dedicated to Professor Stephen T. Hyde on the occasion of his retirement. Professor Hyde’s scientific career has revolved around using the geometric study of structures with negative Euler index (Formula presented)—bicontinuous and other negatively curved surfaces, spatial nets, tangles and knots—to understand the
We have compared the performance of 64 different computational methods, based on combined quantum mechanical (QM) and molecular mechanical (QM/MM) or QM-cluster calculations in a continuum solvent, to estimate the acid constant (pKa) of metal-bound ligands in proteins. As a calibration set, we use 12 experimental pKa values from six different proteins that involve Zn2+, Fe3+, or Fe4+. We employ tw
Background: Heart failure (HF) is a common disease among older individuals and is associated with poor quality of life and prognosis. Individuals at risk of developing HF are usually already patients in primary healthcare, but diagnosing HF at an early stage can be challenging. Identifying patients at risk of HF and initiating early treatment is crucial for their outcomes. Using the variables gend
This study theoretically evaluates the detection time window for assessing internal dose following the inhalation of radionuclides released in a postulated accident scenario at the European Spallation Source (ESS). The assessment focuses on gamma-emitting radionuclides and investigates the feasibility of high-resolution whole-body counting (WBC) and gamma spectrometric analysis of 24-h urinary exc
In this paper, we consider integral linear constraints and the dissipation inequality with linear supply rates for certain sets of trajectories confined pointwise in time to a convex cone which belongs to a finite-dimensional normed vector space. Such constraints are then shown to be satisfied if and only if a bounded linear functional exists which satisfies a conic inequality. This is analogous t
OBJECTIVES: To explore and map the literature on referral pathway gaps and improvement strategies in primary healthcare (PHC) to secondary healthcare (SHC) referrals, and to categorise both gaps and improvements using the Quintuple Aim framework for healthcare improvement-a model encompassing patient experience, population health, costs, provider well-being and health equity. DESIGN: Scoping revie
We study applications of clustering (in particular, the Hamming k-center clustering problem) in the design of efficient and practical algorithms for computing an approximate and the exact arithmetic matrix product of two 0-1 rectangular matrices with clustered rows or columns, respectively. Our results in part can be regarded as an extension of the clustering-based approach to Boolean square matri
Accurate identification of anatomical structures is essential for safe congenital cardiac surgery and for the development of assistive robotic systems. However, scalable annotation of open-heart surgical video remains a major challenge due to dynamic tissue motion, occlusion, and anatomical variability. The aim of this study was to develop and evaluate a human-in-the-loop segmentation and tracking
Objectives: The Queen of Hearts (QoH) ECG artificial intelligence model has demonstrated improved sensitivity for detecting occlusion myocardial infarction (OMI) compared with STEMI criteria, but further validation is needed. We aimed to evaluate QoH's diagnostic performance in patients with chest pain at Swedish emergency departments (EDs). Methods: This retrospective analysis included consecutiv
Aim Infant massage has been suggested as a beneficial approach; however, evidence regarding how it is implemented within routine child health care remains limited. The aim of this observational study was to explore how infant massage education was enacted in a child health care setting, with a focus on infant behavior, caregiver–infant interaction, and group dynamics among caregivers during the se
In insects, antennal ionotropic receptors (IRs) play a crucial role in the detection of airborne chemicals. However, little functional information is available beyond drosophilids, particularly in terms of their functional evolution. In the present study, we functionally assayed IR75q.2 orthologues from eight moth species and found that three of them primarily responded to nonanoic acid, with seco

This thesis examined to what extent Japanese newspapers’ reporting practices may contribute to the legitimisation and normalisation of the xenophobic, far-right populist party Sanseito and its views. While Japan was long considered an exception to the global right-wing populist wave, the anti-immigration, far-right populist Sanseito attracted a surge in votes and became the third-largest oppositio
Detta examensarbete undersöker hur befintliga styrsystem i ABB SattLine kan konverteras till ABB System 800xA på ett mer strukturerat, spårbart och delvis automatiserat sätt. Bakgrunden är att många industriella anläggningar fortfarande använder SattLine trots att systemet idag befinner sig i en sen livscykelfas, vilket skapar behov av modernisering till en plattform med bättre framtida stöd och uThis thesis investigates how existing control systems in ABB SattLine can be converted to ABB System 800xA in a more structured, traceable, and partly automated way. The background is that many industrial plants still rely on SattLine even though the system is now in a late lifecycle phase, creating a need to modernize to a platform with better long-term support and development possibilities.
