TESS Investigation—Demographics of Young Exoplanets (TI-DYE). IV. A Jovian-radius Planet Orbiting a 34 Myr Sun-like Star in the Vela Association
Full text linkpeer reviewedThe discovery of infant (<50 Myr), close-in (<30-day-period) planets is vital in understanding the formation mechanisms that lead to the distribution of mature transiting planets as discovered by Kepler. Despite several discoveries in this age bin, the sample is still too small for a robust statistical comparison to older planets. Here we report the validation of TOI-6448b, an 8.8 ± 0.8 R⊕ planet on a 14.8-day orbit. TOI-6448 was previously identified to be a likely member of Vela Population IV. We confirm the star's membership and rederive the age of the cluster using isochrones, variability, and gyrochronology. We find the star, and thus planet, to be 34 ± 3 Myr. Like other young planets, TOI-6448 b lands in a region of parameter space with few older planets. While just one data point, this fits with prior findings of an excess of 5─11 R⊕ planets around young stars far beyond what can be explained by reduced sensitivity at young ages. Our ongoing searches of Vela, Taurus-Auriga, Sco-Cen, and Orion are expected to reveal dozens more <50 Myr transiting planets

A Systematic Review and Independent Patient Data Meta-Analysis of Prophylactic Mesh Augmentation for Incisional Hernia Prevention after Abdominal Aortic Aneurysm Surgery (I-PREVENT-AAA) A Collaborative European Hernia Society Project.
No full textpeer reviewed[en] OBJECTIVE: To analyze the effectiveness of prophylactic mesh augmentation (PMA) of the abdominal wall following open aortic aneurysm repair as compared to primary sutured closure in preventing incisional hernia (IH) formation by performing an individual patient-data meta-analysis (IPDMA).
SUMMARY BACKGROUND DATA: IH is a prevalent complication after abdominal surgery, especially in high-risk groups. PMA of the abdominal wall has been studied as a preventive measure for IH-formation, but strong recommendations are lacking.
METHODS: A systematic literature search was conducted till 23 September 2024 to identify randomized controlled trials (RCTs) that compared PMA with PS after open AAA surgery. Lead authors of eligible studies were asked to share individual patient-data. A one-stage analysis was performed, and Cox-regression analyses were used to assess time-to-event outcomes.
RESULTS: Five randomized trials with a total of 493 patients were included. Intention to treat analysis revealed that PMA was associated with significantly lower risk of IH (hazard ratio of 0.25 (95% CI 0.12-0.50)) as compared to PS closure. Three-year incisional hernia rates were 13.2% and 39.6%, respectively, with a number needed to treat of 3.7. The effect was similar for onlay and retro-rectus PMA. PMA resulted in longer operative time (mean 27 minutes) and more seroma formation (especially onlay PMA) but did not increase the risk of surgical site infection.
CONCLUSIONS: PMA after elective open abdominal aortic aneurysm surgery is proven to be an effective measure to reduce IH formation and should be considered in future guidelines as standard of care

Debunking the Colonial Narrative in Belgium: Public Space Decolonization in Brussels and Cultural Objects Restitution to Central African Countries
No full textpeer reviewed[CHAPTER]
This chapter analyzes contemporary decolonial thoughts and practices in Belgium, linking the nation's colonial period to the persistence of structural racism against people with sub-Saharan African origins. The chapter argues that Belgium's dominant colonial narrative and propaganda, centered on the "civilizing mission," continue to influence society despite the country's collective memory having largely suppressed its colonial history.
[BOOK]
Revived by the global resonance of the Black Lives Matter movement in 2020, this book adds to the current discussion on the idea of decolonizing Europe. Drawing inspiration from the study of colonialism, postcolonialism and the imperative to decolonize knowledge and practice, the editors bring together a group of scholars approaching these issues through ethnographic inquiry. The volume explores how race, colonial legacies and structural inequality are addressed across diverse European contexts – north, central, eastern and southern – as well as in their entanglements with regions beyond Europe. It offers critical, grounded insights into the possibilities and challenges of decolonial thinking today
Rénovation énergétique du parc immobilier résidentiel wallon : déterminants, typologies et approches intégrées pour des interventions ciblées
No full textAccelerating energy renovation of existing residential buildings is critical for Europe’s climate goals. This thesis investigates the Walloon residential stock through a multidimensional approach integrating technical building characteristics, socio-economic profiles of occupants, and awareness strategies.
Chapter 1 characterizes the Walloon building stock and identifies correlations between technical and socio-economic factors. Statistical analyses highlight key determinants, showing, for example, that a 1% increase in households earning €10,000–20,000 corresponds to 7.22 kWh/m²·y higher average energy consumption. Semi-detached houses with unfavorable technical and socio-economic conditions emerge as priority targets.
Chapter 2 clusters “building–occupant” archetypes using regression analyses and K-means, revealing typologies such as low-performance houses occupied by low-income households (17% of stock) or by high-income households (11%). These insights support targeted, scale-appropriate renovation strategies.
Chapter 3 presents a mixed-methods study in a historic Liège neighborhood, combining surveys, thermography, and focus groups. Results show socio-economic factors often outweigh technical ones in renovation decisions, and that awareness and tailored engagement are essential. Challenges in rental and co-ownership settings highlight the need for locally adapted policies.
Overall, this thesis provides an integrated framework combining statistical modeling, typology-based approaches, and participatory research to guide effective, equitable, and context-sensitive energy renovation in Wallonia
Organizational Benefits of Corporate Entrepreneurship
No full textpeer reviewedEvaluating the benefits of corporate entrepreneurship (CE) is widely recognized as a key driver of innovation, adaptability, and long-term organizational development. While CE initiatives are often praised for enhancing competitiveness and resilience, empirical evidence supporting these claims remains limited and dispersed. Much of the existing literature is conceptual in nature, with insights frequently derived from isolated case studies or anecdotal accounts by business leaders, rather than from systematic empirical research. As a result, few studies provide robust qualitative or quantitative assessments of CE’s direct and indirect impacts on organizational performance, employee engagement, or innovation portfolio and revenues. This lack of methodological rigor has prompted calls within the academic community for more evidence-based investigations into the outcomes of CE. Scientifically grounded insights are essential for organizations aiming to refine their CE strategies and justify resource allocation to intrapreneurial
initiatives. A structured evaluation framework can support this effort by helping firms
measure return on investment (ROI), determine strategic fit, and identify success factors
that sustain innovation over time. Responding to this need, the present chapter
first reviews key theoretical approaches to the organizational benefits of CE. It then draws
on a broad range of case examples spanning nearly four decades to offer an empirically
informed—though non-systematic—analysis of CE’s contributions to business growth and
organizational transformation
