Search for pulsations at high radio frequencies from accreting millisecond X-ray pulsars in quiescence

open access: yes, 2010
It is commonly believed that millisecond radio pulsars have been spun up by transfer of matter and angular momentum from a low-mass companion during an X-ray active mass transfer phase.

Millisecond by Millisecond, Year by Year: Normative EEG Microstates and Developmental Stages

open access: yesNeuroImage, 2002
Most studies of continuous EEG data have used frequency transformation, which allows the quantification of brain states that vary over seconds. For the analysis of shorter, transient EEG events, it is possible to identify and quantify brain electric microstates as subsecond time epochs with stable field topography.

Study on Vibration Effects and Optimal Delay Time for Tunnel Cut-Blasting Beneath Existing Railways

open access: yesApplied Sciences
With the development of underground space in urban areas, the demand for tunneling through existing railways is increasing. The adverse effects of cut-blasting during the construction of tunnels under crossing existing railways are investigated. Combined

Millisecond Pulsar Surveys [PDF]

open access: yesInternational Astronomical Union Colloquium, 1996
Abstract There are now more than 30 millisecond pulsars known to be associated with the Galactic disk. The majority of these have been discovered in just the last few years as the result of large-scale all-sky surveys. The properties of the population vary tremendously.

A Search for Sub-Millisecond Pulsars

open access: yes, 2001
We have conducted a search of 19 southern Galactic globular clusters for sub-millisecond pulsars at 660 MHz with the Parkes 64-m radio telescope. To minimize dispersion smearing we used the CPSR baseband recorder, which samples the 20 MHz observing band ...

Picosecond to Millisecond Structural Dynamics in Human Ubiquitin.

open access: yesJournal of Physical Chemistry B, 2016
Human ubiquitin has been extensively characterized using a variety of experimental and computational methods and has become an important model for studying protein dynamics. Nevertheless, it has proven difficult to characterize the microsecond time scale

Multineuronal Spike Sequences Repeat with Millisecond Precision

open access: yesFrontiers in Neural Circuits, 2013
Cortical microcircuits are nonrandomly wired by neurons. As a natural consequence, spikes emitted by microcircuits are also nonrandomly patterned in time and space.

Rotochemical Heating in Millisecond Pulsars. Formalism and Non-superfluid case

open access: yes, 2005
Rotochemical heating originates in a departure from beta equilibrium due to spin-down compression in a rotating neutron star. The main consequence is that the star eventually arrives at a quasi-equilibrium state, in which the thermal photon luminosity ...
