Summary: The study found that using podcasting to highlight publications about gynecological cancer is associated with higher AAS and citation scores. However, podcasting an article does not necessarily generate a high number of citations per year. Compared to all articles published in the same journal during the same study period, podcasted articles have higher median citations per year.

Summary: This study compared the 10-year clinical outcomes of biodegradable polymer biolimus-eluting stents (BP-BES) and durable polymer everolimus-eluting stents (DP-EES). The results showed that there were no significant differences in safety and efficacy outcomes between BP-BES and DP-EES from 1 year up to 10 years after stent implantation.

Summary: The proposed 2020 Core Curriculum for Percutaneous Cardiovascular Interventions aims to establish a common European consensus and promote uniform education and training. It suggests that competence in interventional cardiology requires at least two years of postgraduate training and four years in cardiology.

Summary: A profound shift in cosmology occurred with the discovery of thousands of exoplanets, but the question of which of these planets are habitable remains unanswered. To address this, researchers propose using a multi-stage memetic algorithm (MSMA) as an anomaly detection method to detect potentially habitable exoplanets.

Summary: Stellar ranging is essential for stellar dynamics and astrophysics research. The parallax method, though widely used, requires precise measurement of parallax angle and baseline length. This study proposes a new stellar ranging scheme based on second-order correlation that eliminates the need for parallax angle measurement. The experiment successfully demonstrates the feasibility of this scheme, which allows for more accurate stellar ranging without prior information or angle measurement.

Summary: This article discusses the design challenges of the Phased Array Feed (PAF) front-end and its signal processing system, and proposes the concept of fully digital receivers. It presents a digital beamforming topology and designs a PAF signal processing experimental system based on RFSoC+GPU hybrid architecture. The performance tests show the effectiveness of the system and the advantages of the RFSoC integrated design.

Summary: The influence of thermal deformation on the performance of reflector antennas has become increasingly significant. The use of a thermal compensation database is an efficient method to compensate for the deformation caused by non-uniform temperature distribution. This study proposes a data match and call method for the thermal compensation database of the reflector antenna, achieving real-time thermal compensation.

Summary: Distinguishing astrophysical black holes from primordial black holes can be achieved through the redshift evolution of their respective merger rates. By using the stochastic gravitational wave background for a joint estimation, it is possible to differentiate between these two populations. The latest constraints on black hole merger rates provide insights for future detector sensitivities in distinguishing between astrophysical and primordial black holes.

Summary: This study explores the synergy between the LVK detectors and spectroscopic galaxy surveys such as DESI and SPHEREx to measure cosmological parameters related to the cosmic expansion history and GW bias parameters. By analyzing the 3D spatial cross-correlation between dark GW sources and spectroscopic galaxy samples, precise measurements of the Hubble constant and dark energy equation of state can be obtained. The combination of Euclid with DESI and SPHEREx shows potential for marginal gains in measuring cosmological parameters, particularly at high redshifts.

Summary: Through neural network and computational models, research has shown that predictable patterns and rules exist within planetary systems, aiding in understanding the formation and evolution of such systems. Two robust groups of planetary systems have been identified, highlighting that planetary systems are not random sequences.

Summary: Classifying the morphologies of galaxies is crucial for understanding their physical properties and evolutionary histories. By training and testing convolutional neural networks (CNNs) on a dataset of visually classified SDSS images, a new CNN architecture was able to outperform existing models in classifying galaxies into 3 and 4 different categories. The study also found that misclassifications may have physical significance, with lenticular galaxies misclassified as elliptical galaxies often being more massive.

Summary: The study investigates the role of gravitational waves in the heat death of the Universe, finding that they lead to energy dissipation in dynamical systems, transitioning to a state of rest and death. Energy loss due to gravitational wave emission in dark matter systems is estimated through N-body simulations, though the analysis may be invalidated by multiple unknown factors.
