Nanoscale confinement of energy deposition in glass by double ultrafast Bessel pulses
Nanophotonics, Volume 10, Issue 3, Page 1089-1097, February 2021., 2021 Abstract Ultrafast laser pulses spatially shaped as Bessel beams in dielectrics create high aspect ratio plasma channels whose relaxation can lead to the formation of nanochannels. We report a strong enhancement of the nanochannel drilling efficiency with illumination by double pulses separated by a delay between 10 and 500 ps.

Probing the composition of sub-millisecond rotating compact stars by r-modes instability [PDF]
, 2012 We investigate the implications of the r-modes instability on the composition of a compact star rotating at a sub-millisecond period. In particular, the only viable astrophysical scenario for such an object, wich might present inside the Low Mass X-ray ...

Spin frequency distributions of binary millisecond pulsars [PDF]
, 2014 Rotation-powered millisecond radio pulsars have been spun up to their present spin period by a 108−109 yr long X-ray-bright phase of accretion of matter and angular momentum in a low-to-intermediate mass binary system.

The Effect of Irradiation on the Spin of Millisecond Pulsars
The Astrophysical Journal Letters, 2023 A millisecond pulsar (MSP) is an old neutron star (NS) that has accreted material from its companion star, causing it to spin up, which is known as the recycling scenario.

Exploring Precision Timing of Millisecond Pulsars with Wide-Bandwidth Observations [PDF]
, 2023 This thesis studies the masses, velocities, and interstellar medium effects of rapidly spinning neutron stars called millisecond pulsars. The masses of seven pulsars and their binary companions are measured.

A Survey for Millisecond Pulsars [PDF]
, 1996 We have searched 960 square degrees of sky for radio pulsars, using the 305 m telescope at Arecibo, Puerto Rico. The 430 MHz survey reached a limiting sensitivity for slow pulsars of 0.7 mJy using a dual-polarization, 32 channel filter bank over 8 MHz of

Scintillation velocities of five millisecond pulsars [PDF]
, 2000 Millisecond pulsars differ from normal pulsars in their mode of origin and their properties. They are thought to be born either through binary interaction or through accretion-induced collapse (AIC) of white dwarf stars.

Discovery of four isolated millisecond pulsars [PDF]
, 1997 We report the discovery of four isolated millisecond pulsars found as part of the Parkes 436 MHz survey of the southern sky. Three of the pulsars, PSRs J1024-0719, J1744-1134, and J2124-3358, are close to the Sun (d <360 pc) and have very low ...

Physiological Reports, Volume 8, Issue 12, June 2020., 2020 Three consecutive days of endurance training under low energy availability (LEA) decreased the muscle glycogen content and increased the serum hepcidin level in well‐trained male long distance runners. These results suggest that LEA is associated with a risk of exercise‐induced iron deficiency by an elevated hepcidin level in endurance athletes ...

Optical pulsations from a transitional millisecond pulsar [PDF]
, 2017 Millisecond pulsars are neutron stars that attain their very fast rotation during a 108-109-yr-long phase of disk accretion of matter from a low-mass companion star(1,2).
