Tadeus Carl, Eva Wirström, Per Bergman, Steven Charnley, Yo-Ling Chuang, Yi-Jehng Kuan One of the most fundamental hypotheses in astrochemistry and astrobiology states that crucial biotic molecules like glycine (NH2CH2COOH) found in meteorites and comets are inherited from early phases of star formation. Most observational searches for glycine in the interstellar medium have focused on…

Marta Reina-Campos, Alison Sills, Godefroy Bichon Massive star clusters are often used as tracers of galaxy formation and assembly. In order to do so, we must understand their properties at formation, and how those properties change with time, galactic environment, and galaxy assembly history. The two most important intrinsic properties that govern star cluster evolution…

The COVID-19 affected communities and the economy beyond public health. The epidemic is expected to increase global poverty and inequality, making it crucial to study its effects. Several international organisations determined that a “new recession” was underway due to the global pandemic’s destructive effects on the financial, social, and personal spheres. Despite their best efforts,…

The evolution of the Universe is observable when the expansive motion already exists; thus, the definition of universal states (before the beginning and after the end of the expansion) with zero kinetic energy can be a challenge to be solved by parallel analysis. Considering that a complete description of the Universe can provide important insights,…

The COVID-19 pandemic had a profound impact on business leadership, specifically on chief executive officers (CEOs). To document the psychological impacts of the pandemic on corporate leadership, this study analyzed the language of CEOs during company quarterly earnings calls (N = 19,536) one year before and after the onset of the pandemic. Following the start…

This paper introduces an advanced method that integrates contingent valuation and machine learning (CVML) to estimate residents’ demand for mitigating environmental pollutions and climate change. To be precise, CVML is an innovative hybrid machine-learning model, and it can leverage a limited amount of survey data for prediction and data enrichment purposes. The model comprises of…

Mental health problems often co-occur, as do physical conditions. There is also comorbidity between mental and physical health problems, such as cancer and depression. In their recent work, Brandt et al. (2023) propose that the d(isease) factor explains why. They define the d factor as an “underlying disease dimension […] that accounts for the individuals’…

Background: Primary avalvular varicose anomalies (PAVA) are found in 4.6% patients with primary varicose veins and can be confused with neovascular tissue. These veins can be found in all compartments of the leg and are found more commonly in patients with pelvic venous reflux. Little is known about these atypical vessels and so we are…

Introduction: Endovenous thermal ablation (EVTA) is the first line treatment of symptomatic truncal venous reflux. Linear Endovenous Energy Density (LEED) is the measure of energy used per cm of treated vein. The rate of application of energy influences thermal spread and tissue damage. However, time is absent from LEED. The aim of this study was…

A description of the changes in the management of superficial venous disease that have occurred in the first two decades of the 21st century are explored. A brief overview of traditional techniques prior to this evolution is also described. Special focus is placed upon the treatment of difficult recurrent venous disease. Newer innovations at the…
