Elliptic flow, eccentricity and eccentricity fluctuations
, 2006 Differential studies of elliptic flow are one of the most powerful tools in studying the initial conditions and dynamical evolution of heavy ion collisions. The comparison of data from Cu+Cu and Au+Au collisions taken with the PHOBOS experiment at RHIC provides new information on the interplay between initial geometry and initial particle density in ...

Catheterization and Cardiovascular Interventions, EarlyView.ABSTRACT Backgrounds Accurate stent positioning in aorto‐ostial lesions remains challenging due to complex three‐dimensional anatomy, lack of optimal fluoroscopic projections, and high rates of geographic miss. Stent overhang impairs guide catheter re‐engagement and complicates future revascularization.

Catheterization and Cardiovascular Interventions, EarlyView.ABSTRACT Background Advanced heart failure (HF) remains a clinical challenge, and mitral transcatheter edge‐to‐edge repair (M‐TEER) has emerged as a potential bridging strategy. Aims To describe the clinical outcomes of M‐TEER in a single‐center cohort of patients with advanced HF and to identify anatomical and clinical features potentially associated ...

Catheterization and Cardiovascular Interventions, EarlyView.ABSTRACT Paravalvular leak (PVL) is a recognized complication after surgical mitral valve replacement and may cause heart failure, pulmonary hypertension, or hemolysis when moderate or severe. Although redo surgery is the definitive treatment, it carries substantial risk in elderly patients or those with multiple prior cardiac surgeries.

A Case of Venous Tissue Dissection During Transcatheter MitraClip Surgery
Catheterization and Cardiovascular Interventions, EarlyView.ABSTRACT The MitraClip system has been widely used to treat mitral regurgitation. The complications associated with MitraClip surgery typically include clip detachment and mitral valve injury. However, cases of venous tissue dissection during surgery are relatively rare.

Automated Process Optimization in a Novel Triple Shaft Mixer with Adaptive Mixing Modes
Chemie Ingenieur Technik, EarlyView.A novel multi‐purpose mixer with adjustable blade angle and a coaxial stirrer is developed, providing three degrees of freedom. An optimization strategy is integrated to autonomously identify optimal operating conditions through automated tests. The current draw of the main stirrer serves as the optimization criterion, while stirrer speeds, directions,

Accreting Binary Eccentricities Follow Predicted Equilibrium Values
The Astrophysical JournalWe investigate observations of circumbinary disks (CBDs) to find evidence for an equilibrium eccentricity predicted by current binary accretion theory.
