Background and Purpose: Hippocampal-sparing (HS) is a method that can potentially reduce late cognitive complications for pediatric medulloblastoma (MB) patients treated with craniospinal proton therapy (PT). The aim of this study was to investigate robustness and dosimetric plan verification of pencil beam scanning HS PT. Materials and Methods: HS and non-HS PT plans for the whole brain part of c
A compact reduced mechanism covering a wide range of conditions is developed for use in simulations of NH3/n-heptane combustion in engines. Reduction targets were selected after reviewing available experimental studies of NH3 combustion in engines. Ignition, flames and oxidation of NH3/n-heptane mixtures were targeted. Particularly, mixtures with very low molar percentage of n-heptane which are im
This study compared two different methods, the satellite altimetry-based and DEM (digital elevation model)-based, for estimating lake water volume changes. We focused on 34 lakes in China as the testing sites to compare the two methods for lake water volume changes from 2005 to 2020. The satellite altimetry-based method used water levels provided by the DAHITI (Database for Hydrological Time Serie
A large number of children with cleft lip and palate (CLP) were adopted to Sweden in the last decade, mainly from China. Most of the children arrived with unoperated palates and at later ages than earlier years. This article aims to present an overview of ethical challenges within the practice of international adoption of children with CLP from the perspective of plastic surgery in a welfare healt
Digital healthcare services and digital health information, here called eHealth services, have the potential to reach people with diverse needs as both a complement to and a substitution for traditional healthcare. The access to and use of digital health information and digital healthcare services that are accessible and usable for people with impairments is a complex phenomenon.This potential is
Background: Communication is a key tool in the nursing profession. It is known that listeners are sensitive to the speaker's voice and interpret the speaker's intentions primarily from the non-verbal signal conveyed. Aim: To map and discuss the current state of knowledge and research evidence on professional voice use in health and nursing care. Design and Method: A scoping review adherent to the
Objective: To evaluate the long-term performance of the patch materials we have used to augment the pulmonary arterial tree across a wide spectrum of diagnoses and anatomical locations. Methods: Retrospective, single-center review of 217 consecutive pediatric patients at a tertiary referral center from 1993 to 2020 who underwent patch arterioplasty of the pulmonary arterial tree from the pulmonary
Since the Russian invasion of Ukraine in 2014, the EU and NATO have strengthened resilience, preparedness, and critical infrastructure policies in response to evolving transboundary threats. However, cascading climate risks, defined as cross-border and cross-sectoral impacts intensified by climate change, have the potential to be insufficiently understood and integrated into EU and NATO frameworks
Our way of handling the climate crisis is not fast or ambitious enough. We have the opportunity to plan for a better future, not just accept the consequences of our failure. To plan for a better future, we first need to conceptualise a vision of a desired end-point, in this case a climate-neutral and sustainable city. This essay is meant to inspire radical change by using and expanding the radical
Access to digital infrastructure in highly digitalized societies is shaped not only by the availability of technology but also by the administrative arrangements that govern access to it. This study examines how non-EU international students at Lund University experience and navigate exclusion from Sweden’s digital financial infrastructure through the case of Swish, a mobile payment system widely
Technical drawings play an important role in many industrial processes, including product development, manufacturing, and lifecycle management, by representing the product definition. The purpose of the study was to investigate which processes influence technical drawing creation and management, what challenges are associated with these processes, and how these challenges can be addressed through
This thesis presents the design and schematic-level simulation of a highly linear mixer-first receiver front-end implemented in CMOS, targeting improved robustness against strong input signals. The proposed architecture employs a current-mode passive mixer directly loaded by a low-impedance transimpedance amplifier (TIA) in order to minimize the voltage swing at the mixer output and thereby enhanc
Developing high-temperature proton exchange membranes (HT-PEMs) that simultaneously achieve high proton conductivity, strong phosphoric acid (PA) retention, and long-term chemical stability remains a major challenge, particularly due to PA-induced plasticization and radical-induced oxidative degradation. Here, we develop a side-chain engineering strategy to decouple PA-binding sites from the polym
With approximately 94 percent of traffic accidents being caused by human error, improving driver behaviour has the potential to save lives. To encourage safer driving, Volvo Cars is developing a Safety Coach feature for their mobile application. However, pilot studies of a minimum viable product (MVP) indicated low user retention, suggesting the need for design elements that better support user en
Universities are widely understood to be sites of free expression, knowledge-seeking institutions that serve the public good while encouraging personal development of individuals. They typically uphold and communicate institutional integrity and ethics, seeking to encourage open communication, equip students with critical thinking, and foster civil participation. For the Social Sciences, questions
OBJECTIVE: Anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitides (AAV) are chronic, relapsing inflammatory diseases, yet reliable biomarkers for detecting relapse and organ involvement remain limited. This study aimed to identify plasma protein biomarkers that distinguish active disease from remission and to explore markers associated with lung and kidney involvement.METHODS: Plasma
Background: Data are lacking on left ventricular ejection fraction (LVEF) trajectory following myocardial infarction (MI). Objectives: This study aimed to evaluate the impact of LVEF trajectory after percutaneous coronary intervention (PCI) for MI on long-term outcomes. Methods: Patients undergoing PCI for MI (2007-2022) with serial echocardiograms were identified in the Swedish Coronary Angiograp
The continuum mechanics fatigue model operates on state variables that are continuous in time, unlike cycle-counting-based methods that rely on deconstructing stress histories into a set of distinct cycles. This way, the continuum-based approach provides a modeling framework that, in principle, can handle arbitrary stress histories. Despite its successful application for a wide range of problems,
Accounting for bioenergy's carbon dioxide (CO2) emissions, as done under the Kyoto Protocol (KP) and European Union (EU) Emissions Trading Scheme, fails to capture the full extent of these emissions. As a consequence, other approaches have been suggested. Both the EU and United States already use value-chain approaches to determine emissions due to biofuels - an approach quite different from that
