Background: FLASH radiotherapy (RT) is a novel method for delivering ionizingradiation, which has been shown in preclinical studies to have a normal tissuesparing effect and to maintain anticancer efficacy as compared to conventionalRT. Treatment of head and neck tumors with conventional RT is commonlyassociated with severe toxicity, hence the normal tissue sparing effect of FLASHRT potentially ma
Introduction: Most studies determining speakers’ perceived gender as binarily female or male are reliant on F0 perception, although other vocal parameters may also contribute to the perception of gender. The current study focused on the impact of breathiness on the perception of speakers’ gender as a biological variable (feminine or masculine). Methods: n = 31 normal hearing, native English speake
BackgroundOlder patients are often vulnerable and highly dependent on healthcare professionals’ assessment in the event of acute illness. In the context of ambulance services, this poses challenges as the assessment is normally conducted with a focus on identifying life-threatening conditions. Such assessment is not fully satisfactory in a patient relationship that also aims to promote and protect
Study region: In the Yangtze River basin of China. Study focus: We applied a recently popular deep learning (DL) algorithm, Transformer (TSF), and two commonly used DL methods, Long-Short-Term Memory (LSTM) and Gated Recurrent Unit (GRU), to evaluate the performance of TSF in predicting runoff in the Yangtze River basin. We also add the main structure of TSF, Self-Attention (SA), to the LSTM and G
Cardiovascular diseases (CVDs) remain a leading cause of death globally. According to the American Heart Association, approximately 19.1 million deaths were attributed to CVDs in 2020, in particular, ischemic heart disease and stroke. Several known risk factors for CVDs include smoking, alcohol consumption, lack of regular physical activity, and diabetes. The last decade has been characterized by
BackgroundPolypharmacy is increasing. The longitudinal association of polypharmacy and social isolation has not been previously reported. The aim of this study was to explore longitudinal associations of polypharmacy with loneliness and social isolation among older adults.MethodsParticipants aged 60 years and above in southern Sweden were invited for participation. A total of 1526 and 2556 partici
Phytoplankton have short generation times, flexible reproduction strategies, large population sizes and high standing genetic diversity, traits that should facilitate rapid evolution under directional selection. We quantified local adaptation of copper tolerance in a population of the diatom Skeletonema marinoi from a mining-exposed inlet in the Baltic Sea and in a non-exposed population 100 km aw
Urbanization is causing impact on biodiversity and ecosystem services globally, due to disturbance, fragmentation and loss of habitats as the proportion of urban settlement increases. Actions for enhancement of biodiversity in urban spaces become important to achieve a sustainable urbanization. Wihlborgs Fastigheter AB, a housing company in the Öresund Region, has installed eleven nest boxes for b
The purpose of this study is to compare the different short-term interest rate models, and to identify the better model within multiple countries. We selected three different types of data from the United States, the United Kingdom, and New Zealand. We compare the models with the historical data within these three countries, and figure out whether different countries could have their own best mode
The purpose of this thesis is to develop a blind spot detection system for increased safety and comfort for a biker. The solution is based on power-efficient small A111 radars, developed by Acconeer AB, which have a range up to seven meters while consuming only a few milliwatts. Sensor evaluation is performed for the intended use and from this, concepts are generated. These are tested to obtain t
Germany’s Energy Concept aims to reduce the building sector’s primary energy demand by 80% compared to 2008 levels, of which 20% are to be achieved by 2020. This requires significant investment in integrated renewables and thermal. Public funds cannot finance such transition alone. Therefore, it is crucial to not only understand current investment levels and potential investment gaps, but also to
The purpose of this paper is to design a new lightweight and compact antenna system for harmonic radar applications to be used to trace the migration of the Bogong moths. The main approach adopted in this paper to solve this problem is to build three antennas suitable for use in the real environment, where the modeling and the simulations were done in CST Microwave Studio Suite 2018. The principle

Background Screening with digital breast tomosynthesis (DBT) detects more cancers than with digital mammography (DM), but has small effect, if any, on interval cancer incidence. Methods Data were pooled from two randomized trials within the MAITA Consortium, including 100743 women (664 cancers) screened at baseline and 82938 women (550 cancers) followed for cumulative incidence at subsequent round
Carbon monoxide (CO) poisoning is a leading cause of environmental poisoning in the United States and can impair cellular metabolism through both hypoxia and direct mitochondrial toxicity, particularly via inhibition of cytochrome c oxidase (Complex IV, CIV). In this study, we performed a comprehensive assessment of the cerebral metabolic response to CO exposure in a swine model. Twenty-nine swine
BACKGROUND: Early diagnosis and treatment of breast cancer-related arm lymphedema (BCRAL) is essential to prevent progression. Local tissue water (LTW) can be assessed using the tissue dielectric constant (TDC), enabling detection before an increase of arm volume occurs. However, knowledge of the variation of LTW during cancer treatment and appropriate LTW thresholds for early detection of BCRAL i
Volume status of a patient is difficult to assess clinically. Methods to measure plasma volume as well as changes in plasma volume in connection with fluid therapy are therefore valuable for research purposes and could potentially be used bedside to guide fluid therapy in individual patients. The objective of the present study was to evaluate hematocrit as a marker of changes in plasma volum
