Lagrangian dynamics and spatial distribution of particles in rotating turbulence

Federico Pizzi, David Martín, Mona Rahmani, G. Mamatsashvili et autres

The dynamics of Lagrangian particles dispersed in rotating turbulence differ fundamentally from those observed in classical homogeneous isotropic turbulence (HIT). Rotation induces a pronounced two dimensionalisation of the carrier flow, governed by inertial waves and coherent columnar vortices, while particles experience additional …

Feasibility and Outcomes of Intravenous Lithotripsy as an Adjunct in Complex Transvenous Lead Extraction

Mohamad Mdaihly, Joe Demian, Arshneel S. Kochar, David Martín et autres

BACKGROUND: Transvenous lead extraction (TLE) of old leads is associated with increased procedural complexity and risk due to the development of calcified vascular adhesions. This may necessitate additional tools to free the leads. Shockwave intravenous lithotripsy (IVL), which employs acoustic pressure waves …

Turbulence statistics of homogeneous isotropic supercritical fluid flow

David Martín, Joan Grau, Lluís Jofre

At supercritical pressures, intermolecular forces and molecular packing effects strongly influence fluid behavior, leading to thermodynamic and transport properties that differ significantly from those at subcritical pressures. At these conditions, the resulting high-pressure thermodynamic state space can be divided into liquidlike and …

Abstract 4367494: Procedural Outcomes of Transvenous Lead Extraction in Patients with Prior Sternotomy: Insights from a Large Volume US Center

Mohamad Mdaihly, Joseph Hajj, Arwa Younis, Joe Demian et autres

Background: A history of prior sternotomy has been debated as either a protective factor or a risk for worse outcomes in patients undergoing transvenous lead extraction (TLE). The safety and efficacy of extraction in this population remain incompletely explored. Objective: To evaluate …

Abstract 4342337: Cardiovascular, Kidney, and Metabolic (CKM) Syndrome is associated with increased risk for arrhythmia recurrence following atrial fibrillation (AF) ablation

Sojin Y. Wass, Arwa Younis, Bryan Baranowski, Mandeep Bhargava et autres

Background: The concept of CKM syndrome reflects our evolving understanding that cardiovascular disease, including AF, is intricately connected to other systemic conditions. Objectives: To determine if the odds of AF recurrence following AF ablation changes with the presence of CKM syndrome and …

Abstract 4369182: Sex-Based Outcomes of Transvenous Lead Extraction at a Large-Volume US Center

Joe Demian, Arwa Younis, Abdel Hadi El Hajjar, Mohamad Mdaihly et autres

Background: Transvenous lead extraction (TLE) is a well-established procedure with expanding indications in contemporary practice. However, sex-specific outcomes remain understudied, and women are typically underrepresented in TLE cohorts. Most available data emphasize overall procedural safety and efficacy, without stratifying by sex. Hypothesis: …

Conditional POD for predicting extreme events in turbulent flow time signals

David Martín, Joan Grau, Lluís Jofre

Extreme events in turbulent flows are rare, fast excursions from typical behavior that can significantly impact systems performance and reliability. Predicting such events is challenging due to their intermittent nature and rare occurrence, which limits the effectiveness of data-intensive methods. This paper, …

High-fidelity database of supercritical homogeneous isotropic turbulence in the pseudo-boiling region

David Martín, Lluís Jofre

Supercritical fluids operate above their critical point and are characterized by strong nonlinearities in the equation of state, highly non-ideal fluid behavior, and a tight coupling between thermodynamics and transport properties. As a result, supercritical fluid flows behave fundamentally different from their …

Recurrence patterns and post-recurrence survival of patients with bilobar colorectal liver metastases: international multicentre retrospective study

Ajith K Siriwardena, Alejandro Serrablo, Alexander Novotny, Alfred Know et autres

The liver is the most frequent site of colorectal metastases. Approximately 20% of patients presents with synchronous metastases1. Lifetime incidence of liver metastases in colorectal cancer patients is 50%. Up to 70% of patients develop hepatic or extrahepatic recurrent disease, often within …
