Pacing and Clinical Electrophysiology, Volume 49, Issue 1, Page 25-31, January 2026.Abstract Electrode design and reliable contact assessment are critical for creating durable pulsed field ablation (PFA) lesions to treat atrial fibrillation while minimizing collateral damage. This review introduces a novel “map‐and‐ablate” PFA catheter featuring flat electrodes, thermal contact assessment, and fully customizable electrode selection ...

Discovery of Five Binary Radio Pulsars
The Astrophysical Journal, 2001 We report on five binary pulsars discovered in the Parkes multibeam Galactic plane survey. All of the pulsars are old, with characteristic ages 1-11 Gyr, and have relatively small inferred magnetic fields, 5-90e8 G. The orbital periods range from 1.3 to 15 days.

The Intrabinary Shock and Companion Star of Redback Pulsar J2215+5135
The Astrophysical JournalPSR J2215+5135 (J2215) is a “redback” spider pulsar, where the intrabinary shock (IBS) wraps around the pulsar rather than the stellar-mass companion. Spider orbital light curves are modulated, dominated by their binary companion thermal emission in the ...

Advanced Intelligent Systems, Volume 7, Issue 12, December 2025.A compressed sensing (CS)‐based feature selection method is proposed to select the most informative elements in the radiomic features extracted from medical images of personalized ultra‐fractionated stereotactic adaptive treatment. The CS‐based approach is able to simplify the feature selection process and enhance the accuracy and robustness of a ...

A Relativistic Double Neutron Star Binary PSR J1846-0513
The Astrophysical Journal LettersWe report the timing analysis of PSR J1846−0513, a pulsar discovered by the Five-hundred-meter Aperture Spherical radio Telescope (FAST) in Commensal Radio Astronomy FAST Survey. The pulsar possesses a spin period of 23.36 ms and a spin-down rate ( $\dot{

Journal for the Theory of Social Behaviour, Volume 55, Issue 4, December 2025.ABSTRACT Humanity seems stuck on different ways to fail to meet the challenge posed by a declared climate emergency and manifest problems of ecological breakdown. Rather than reprise these failures, we use the Fermi Paradox and simulation hypothesis to make a simple point about agency. The argument unfolds in two sections.

RELATIVISTIC SPIN-PRECESSION IN BINARY PULSARS [PDF]
The Twelfth Marcel Grossmann Meeting, 2012 After the first prediction to expect geodetic precession in binary pulsars in 1974, made immediately after the discovery of a pulsar with a companion, the effects of relativistic spin precession have now been detected in all binary systems where the magnitude of the precession rate is expected to be sufficiently high.

CHIME Discovery of a Binary Pulsar with a Massive Nondegenerate Companion
The Astrophysical Journal, 2023 Of the more than 3000 radio pulsars currently known, only ∼300 are in binary systems, and only five of these consist of young pulsars with massive nondegenerate companions.

New Arabic Records From Cairo on Supernovae 1181 and 1006
Astronomische Nachrichten, Volume 346, Issue 9, November 2025.ABSTRACT The remnant of the historical supernova SN 1181 is under discussion: While the previously suggested G130.7+3.1 (3C58) appears too old (3000–5000 year), the unusual star IRAS00500+6713 with a surrounding nebula (Pa‐30) has an expansion age not inconsistent with a SN Iax explosion in ad 1181 under the assumption that neither acceleration nor ...
