We report on the discovery and spectroscopic confirmation of TOI-2458 b, a transiting mini-Neptune around an F-type star leaving the main-sequence with a mass of M∗ = 1.05 ± 0.03 M⊙, a radius of R∗ = 1.31 ± 0.03 R⊙, an effective temperature of Teff = 6005 ± 50 K, and a metallicity of 0.10 ± 0.05 dex. By combining TESS photometry with high-resolution spectra acquired with the HARPS spectrograph, we

Objectives: We aimed to describe the cardiopulmonary function during exercise and the health-related quality of life (HRQoL) in patients with a history of COVID-19 pneumonia, stratified by chest computed tomography (CT) findings at baseline. Methods: Among 77 consecutive patients with COVID-19 who were discharged from the Pulmonology Ward between March 2020 and April 2021, 28 (mean age 54.3 ± 8.6

Atrial fibrillation and heart failure have both been suggested to increase stroke and dementia risk. However, in observational studies, reversed causation and unmeasured confounding may occur. To mitigate these issues, this study aims to investigate if higher genetic risk for atrial fibrillation and heart failure increases dementia and stroke risk. Data were obtained from the population-based Goth

Objective: Progressive Supranuclear Palsy (PSP) is a severe neurodegenerative disease characterized by tangles of hyperphosphorylated tau protein and tufted astrocytes. Developing treatments for PSP is challenging due to the lack of disease models reproducing its key pathological features. This study aimed to model sporadic PSP-Richardson's syndrome (PSP-RS) using multi-donor midbrain organoids (M

The EU AI Act aims to regulate artificial intelligence (AI) in a way that balances innovation and protection from harms, but faces the challenge of keeping pace with the development of AI. This paper examines the tension between fixity and flexibility when regulating AI in the EU by drawing on literature on the pacing problem and anticipatory governance, contrasted by sociolegal theory on the impo

Chest pain is one of the most common reasons for emergency department (ED) visits. Extensive diagnostic testing is often performed to identify acute coronary syndrome (ACS), but only about 10% of patients ultimately receive an ACS diagnosis. These diagnostic processes are costly, time-consuming, and sometimes invasive, carrying inherent risks. Additionally, most patients with suspected ACS are adm

This paper deals with the centroid and formation control problem of multi–agent robotic systems. The proposed solution is based on a leader–follower scheme, where only a subset of agents, i.e., the leaders, knows the desired trajectories for the centroid and the formation of the system, while the other agents, i.e., the followers, are required to estimate them through a dynamic consensus scheme. T

Post-heroic perspectives on leadership, which approach leadership as process, practice and a relational phenomenon, have shifted the theoretical understanding from individual characteristics to significant so-called moments of leadership, where direction emerges, and actions are re-oriented and organized. However, despite considerable theoretical development, research struggles to explore these pr

Continuous experimentation (CE) is a software development approach where product decisions are data-driven. Large global internet-facing companies such as Microsoft, Google, and Facebook apply the practice by leveraging their massive user bases to obtain high statistical significance in experimentation results. However, companies with smaller user bases, such as small- and medium-sized enterprises

Using molten salts for etching aluminum (Al) away from the MAX phase for MXene synthesis is an attractive alternative method that allows one to avoid the use of toxic hydrofluoric acid (HF) solutions. However, the mechanism of the MAX phase reaction with molten salts remains to date unclear due to the lack of in situ data. Here, we present a detailed in situ time-resolved synchrotron radiation X-r

Lean, premixed, swirl-stabilized flames are widely used in modern Dry Low Emissions gas turbine combustors; however, the turbulent combustion process under those conditions is known to be extremely sensitive and prone to instabilities. Numerical simulations can be a valuable tool in predicting the effects of alternative fuels; however, the sensitivity of the results to different models ought to be

The minimal SO(10) grand unified theory, augmented by higher-dimensional operators, is based on the following Higgs representations: adjoint 45H, spinor 16H, and complex vector 10H. It was recently realized that, as opposed to the conventional wisdom, any intermediate mass scale has to lie close to the grand unification one. This bears profound consequences for the scalar particles mass spectrum a

BACKGROUND: Exertional breathlessness is a major symptom in cardiorespiratory disease and is often assessed using the modified Medical Research Council (mMRC) questionnaire. The mMRC might underestimate exertional breathlessness in people with impaired exercise capacity who have reduced their physical activity to avoid the symptom. We aimed to evaluate the ability of mMRC to detect abnormally high

The plasma proteome is maintained by the influx and efflux of proteins from surrounding organs and cells. To quantify the extent to which different organs and cells impact the plasma proteome in healthy and diseased conditions, we developed a mass-spectrometry-based proteomics strategy to infer the tissue origin of proteins detected in human plasma. We first constructed an extensive human proteome

Surgical systems are complex and susceptible to external system pressures. The SARS-CoV-2 pandemic and its impact on elective surgery illustrated this. The reassignment of resources to the acute care of patients with COVID-19 led to cancellations of elective services that varied according to surges of the pandemic. Overall, it was estimated that more than 28 million operations were cancelled or po
