Effect of modelling the air in rooms on the prediction of vibration transmission in cross-laminated timber buildings

Timber buildings are intrinsically lightweight and hence can be susceptible to low-frequency vibrations and structure-borne noise. So, within the development of technical solutions for mitigating unwanted vibrations and noise, accurate and computationally efficient numerical models are considered to be of great value. Such models should take into account all physical phenomena that are relevant fo

Health care utilization among individuals who die by suicide as compared to the general population : a population-based register study in Sweden

BACKGROUND: Globally, 700 000 people die every year by suicide. Health care consultation patterns the period before suicide could be one potential way to identify people at risk for suicide. Therefore, this study examines health care patterns up to one year prior to the suicide by age, sex and prior diagnoses and specifically investigates if and how this differs from the general population of Skån

The management of lupus nephritis as proposed by EULAR/ERA 2019 versus KDIGO 2021

In 2019 and 2021, the European League for Rheumatism (EULAR) jointly with the European Renal Association (ERA) and the Kidney Disease: Improving Global Outcomes (KDIGO), respectively, released updated guidelines on the management of lupus nephritis (LN). The Immunology Working Group of the ERA reviewed and compared both updates. Recommendations were either consistent or differences were of negligi

High aspect ratio silicon structures by displacement Talbot lithography and Bosch etching

Despite the fact that the resolution of conventional contact/proximity lithography can reach feature sizes down to ∼0.5-0.6 micrometers, the accurate control of the linewidth and uniformity becomes already very challenging for gratings with periods in the range of 1-2 μm. This is particularly relevant for the exposure of large areas and wafers thinner than 300 μm. If the wafer or mask surface is n

Distinct global binding patterns of the Wilms' tumor gene 1 (WT1) -KTS and +KTS isoforms in leukemic cells

The zinc finger transcription factor Wilms' tumor gene 1 (WT1) acts as an oncogene in acute myeloid leukemia. A naturally occurring alternative splice event between zinc fingers three and four, removing or retaining three amino acids (+/-KTS), is believed to change the DNA binding affinity of WT1, although there are conflicting data regarding the binding affinity and motifs of the different isofor

The Association Between Quadriceps Strength and Synovitis in Knee Osteoarthritis : An Exploratory Study From the Osteoarthritis Initiative

OBJECTIVE: The aim of this study was to explore the association between quadriceps strength and synovitis in knee osteoarthritis (KOA). METHODS: This study was derived from the Osteoarthritis Initiative (OAI), which recruited adults from the OAI cohort with or at risk of KOA. Knees with complete records of isometric quadriceps strength and effusion-synovitis and Hoffa-synovitis assessments were in

Reconfigurable quantum-optical circuits in a complex medium

Programmable optical circuits form a key part of quantum technologies today. As the size of such circuits is increased, maintaining precise control over every individual component becomes challenging. Here we show how embedding an optical circuit in the higher-dimensional space of a large mode-mixer allows us to forgo control over individual elements, while retaining a high degree of programmabili

Residual Stroke Risk Among Patients With Atrial Fibrillation Prescribed Oral Anticoagulants : A Patient-Level Meta-Analysis From COMBINE AF

BACKGROUND: Despite oral anticoagulation, patients with atrial fibrillation (AF) remain at risk of ischemic stroke and systemic embolism (SE) events. For patients whose residual risk is sufficiently high, additional therapies might be useful to mitigate stroke risk. METHODS AND RESULTS: Individual patient data from 5 landmark trials testing oral anticoagulation in AF were pooled in A Collaboration

Entropy-based spatial heterogeneity analysis in pathological images for diagnostic applications

Clinical pathological diagnosis and prognosis for cancer is often confounded by spatial tissue heterogeneity. This study investigates the utility of entropy as a robust quantitative metric of spatial disorder within Fourier Transform Infrared (FTIR) chemical images of breast cancer tissue. The use of entropy is grounded in its capacity to encapsulate the complexities of pixel-wise spectral intensi

A surrogate model to describe uncertainties in wood floor modal frequencies

Wooden multi-story buildings have increased their market share in Europe over the last decades, mainly due to their relatively small carbon footprint and rapid onsite construction. Compared to more conventional heavy concrete buildings, wooden buildings are more sensitive to dynamic loads at low frequencies. Moreover, the dynamic response is generally more difficult to predict. This is, for exampl

Influence of uncertain parameters on modal properties of wood floors

The use of wood as load-bearing material in residential and office buildings has increased significantly in Europe over the last decades. Such buildings often have wooden floors built with boards supported by joists and/or beams. The modal properties of such floors are important regarding the floors’ dynamic response to walking and other usage as well as structure-borne vibration and re-radiated n

DIAGNOSTIC RELIABILITY OF MEASUREMENT OF PREMATURE VENTRICULAR COMPLEX FREQUENCY RELATED TO DURATION OF AMBULATORY MONITORING

Background Premature ventricular complexes (PVCs) are generally quantified using a 24h ECG recording, but the diagnostic accuracy is unknown. We aimed to determine the day-to-day variability and optimal monitoring duration for PVC measurements among patients with frequent PVCs. Methods We included all patients who underwent a clinical ambulatory ECG recording lasting 25-30 days, using the PocketEC

Transcriptomic profiling of T-cell populations in non-muscle invasive and muscle invasive bladder cancer.

Background: Bladder cancer is categorized as non-muscle invasive (NMIBC) or muscle invasive (MIBC). NIMBC makes up around 70% of the cases and although it is less aggressive, the recurrence rate is 50-70%, thus requiring extensive monitoring. Additionally, there is a risk of progression into MIBC with a 5-year survival of only 50% even when treated with radical cystectomy. Immune checkpoint inhibi
