Red Noise Suppression in Pulsar Timing Array Data Using Adaptive Splines
UniverseNoise in Pulsar Timing Array (PTA) data is commonly modeled as a mixture of white and red noise components. While the former is related to the receivers, and easily characterized by three parameters (EFAC, EQUAD and ECORR), the latter arises from a mix ...

Ab-initio Pulsar Magnetosphere: Particle Acceleration in Oblique Rotators and High-energy Emission Modeling [PDF]
, 2017 We perform global particle-in-cell simulations of pulsar magnetospheres, including pair production, ion extraction from the surface, frame-dragging corrections, and high-energy photon emission and propagation. In the case of oblique rotators, the effects

British Journal of Pharmacology, Volume 182, Issue 23, Page 5706-5733, December 2025.Pulmonary arterial hypertension (PAH) is a progressive and life‐threatening disease with limited treatment options. Sex differences are apparent in PAH, specifically in the pathophysiology, prognoses and pharmacological responses of patients. Inflammation and its resolution, which often differ between sexes, are dysregulated in chronic inflammatory ...

Calculation of radar signals delay to second order in the frame of the General Relativity Theory
ACI Avances en Ciencias e Ingenierías, 2014 From the Schwarzschild metric, the light delay due to a gravitational field is calculated to second order approximation in the gravitational potential. We analize the contribution of the second order terms for strong gravitational fields as the generated

Early phases of different types of isolated neutron star
, 2004 Two Galactic isolated strong X-ray pulsars seem to be in the densest environments compared to other types of Galactic pulsar. X-ray pulsar J1846-0258 can be in an early phase of anomalous X-ray pulsars and soft gamma repeaters if its average braking ...

Advanced Science, Volume 12, Issue 43, November 20, 2025.Lipopolysaccharide (LPS) stimulates the production of succinic acid in lung tissue, which promotes macrophages endocytosis and the formation of multivesicular bodies (MVBs). These MVBs release profibrotic extracellular vesicles (EVs), facilitating the transfer of integrin beta1 (ITGβ1) transfer and subsequently activating fibroblasts, thereby ...

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 ...
