Cyclical Changes in the Timing Residuals from the Pulsar B0919+06
, 2010 We report the detection of a large glitch in the pulsar B0919+06 (J0922+0638). The glitch occurred in 2009 November 5 (MJD 55140) and was characterized by a fractional increase in the rotation frequency of Deltanu/nu=1.3x10^{-6}.

Neutron star characteristics from the neutron structure
Frontiers in Physics, 2023 We draw insight into the neutron star structure and characteristics from the neutron structure. The eigenvectors of the special unitary group, SU(3), describing baryons, imply that neutron quarks reside on three faces of a tetrahedron.

Peculiar Glitch of PSR J1119-6127 and Extension of the Vortex Creep Model
, 2014 Glitches are sudden changes in rotation frequency and spin-down rate, observed from pulsars of all ages. Standard glitches are characterized by a positive step in angular velocity ($\Delta\Omega$ $ > $ $0$) and a negative step in the spin-down rate ...

The possible role of r-modes in post-glitch relaxation of Crab [PDF]
, 1999 The loss of angular momentum through gravitational radiation, driven by the excitation of r-modes, is considered in neutron stars having rotation frequencies smaller than the associated critical frequency.

Studia Litteraria et Historica, 2020 On the one hand, the sphere of art offers the possibility to imagine a different, less oppressive and normative world, where just as in the case of cartoons even the greatest gawks, misfits, and outcasts would build friendships and alliances helping ...

La música como punto de partida de la composición visual de imágenes
Grafica: Documents de Disseny Gràfic, 2017 Este trabajo estudia la generación de imágenes desde un punto de vista no visual, desde diferentes disciplinas, hasta llegar a la música como germen de una imagen. Para ello se han analizado en primer lugar las bases disciplinares gráficas.

, 2004 A starquake mechanism for pulsar glitches is developed in the solid quark star model. It is found that the general glitch natures (i.e., the glitch amplitudes and the time intervals) could be reproduced if solid quark matter, with high baryon density but

From Bug to Feature: Harnessing Cross‐Sensitivity for Multiparametric Luminescence Sensing
Advanced Functional Materials, EarlyView.Cross‐sensitivity in luminescence sensing is reframed from a limitation into a resource for multiparametric detection. Using ruby microspheres as a model system, cross‐sensitivity is quantitatively assessed and exploited through linear discriminant analysis, enabling simultaneous, correction‐free pressure and temperature sensing with a single ...

Pulse Profile Change Possibly Associated with a Glitch in an Anomalous X-Ray Pulsar 4U 0142+61
, 2004 We report a glitch-like pulse frequency deviation from the simple spin-down law in an anomalous X-ray pulsar (AXP) 4U 0142+61 detected by ASCA observations. We also found a significant pulse profile change after the putative glitch. The glitch parameters

Real‐Time 3D Ultrasound Imaging with an Ultra‐Sparse, Low Power Architecture
Advanced Healthcare Materials, EarlyView.This article presents a novel, ultra‐sparse ultrasound architecture that paves the way for wearable real‐time 3D imaging. By integrating a unique convolutional array with chirped data acquisition, the system achieves high‐resolution volumetric scans at a fraction of the power and hardware complexity.
