Inference and simulation in the context of high-dimensional dynamical systems remain computationally challenging problems. Some form of dimensionality reduction is required to make the problem tractable in general. In this paper, we propose a novel approximate Gaussian filtering and smoothing method which propagates low-rank approximations of the covariance matrices. This is accomplished by projec
Primary graft dysfunction (PGD) remains a challenge for lung transplantation (LTx) recipients as a leading cause of poor early outcomes. New methods are needed for more detailed monitoring and understanding of the pathophysiology of PGD. The measurement of particle flow rate (PFR) in exhaled breath is a novel tool to monitor and understand the disease at the proteomic level. In total, 22 recipient
Background: Cystic fibrosis (CF) is most common in populations of Northern European ancestry where the F508del variant predominates. In 2020, Iceland became a member of the European Cystic Fibrosis Society Patient Registry, and we launched an epidemiological study of CF in Iceland. The study aimed to determine the prevalence and the genetic variants present in the country. Furthermore, we aimed to
Although many studies have shown that teachers' vocal health is challenged by noise and the room acoustics, research on classroom sound environment from the perspective of teachers' well-being is scarce. This study aimed to explore the relationship between teachers' wellbeing, voice use and classroom acoustics. In this study, wellbeing refers to self-reported vocal health, self-assessed level of s
Introduction: The current standard treatment for endometrial cancer is a laparoscopic hysterectomy with adnexectomies and bilateral sentinel node resection. A retroperitoneal vNOTES sentinel node resection has several theoretical potential advantages. These include being less invasive, leaving no visible scars, operating without Trendelenburg, and therefore offering the anesthetic advantage of eas
Music therapy is a “vocally demanding profession” [1, p. 46]. Currently, little is known about the prevalence and about the possible risk factors for voice disorders within music therapy. As music therapy workspaces may not always be ideal in terms of acoustics, the aim of the study is to investigate room acoustics and noise as risk factors for possible voice disorders among music therapists in Fi
Is circular economy a wonderful thing with no problems that can solve the climate crisis all by itself? Of course not. Can examining the problems with circular economy help us to better apply its principles and achieve better results?Yes. Dr Alison Stowell and colleagues Professor Hervé Corvellec and Dr Nils Johansson outline criticisms of the principle, and how they could help make the circular e
We program high-dimensional linear optical circuits within a commercial multi-mode fibre, turning it into a generalised multi-outcome measurement device, which allows us to both transport and certify high-dimensional entanglement within the transmission channel itself.
Objective: In this study, we propose a novel framework that utilizes deep learning and attention mechanisms to predict the radiographic progression of patellofemoral osteoarthritis (PFOA) over a period of seven years. Design: This study included subjects (1832 subjects, 3276 knees) from the baseline of the Multicenter Osteoarthritis Study (MOST). Patellofemoral joint regions-of interest were ident
Projektet har fokus på kvalitetskontroll av markstabilisering med elektrisk resistivitetstomografi (ERT). Stabilisering kan göras i form av KC-pelare, jetpelare, ytstabilisering och masstabilisering, genom inblandning av cement, kalk, slagg, flygaska eller kombinationer av dessa. Markstabilisering kan vara mycket attraktivt för såväl miljö som ekonomi, men det finns behov av bättre metoder för kva
In the later Middle Ages and early modern period, many European hospitals developed into commercial retirement homes that allowed investors to pay for lifelong food and lodging. Their clients consisted mainly of elderly citizens who decided to spend their final years enjoying a pension, often living by themselves or occasionally with a spouse. Corrodies can best be understood as life annuities in
Aims: To determine whether a family history of unexplained heart failure (HF) in first-degree relatives (children or sibling) increases the rate of unexplained HF. Methods and results: Using Danish nationwide registry data (1978–2017), we identified patients (probands) diagnosed with first unexplained HF (HF without any known comorbidities) in Denmark, and their first-degree relatives. All first-d

Anaerobic fermentation, compared to aerobic processes, remains the most scalable method for bioproduction of compounds. This is due to that aerobic microbial processes require large amounts of energy and are unable to satisfy the oxygen demand of a high-density microbial biomass. Thus, anaerobic microbes are readily scalable to large volumes. It was found that most anaerobic microbes have evolved
Plant production systems worldwide are struggling to meet the diverse and increasing needs of humankind while also facing challenges such as climate change and biodiversity loss. This, combined with the desirable transition from the use of conventional pesticides to more sustainable plant protection solutions, has led to an urgent, and increasing, need for lowrisk plant protection products (PPPs)
