Molecular Domino Toppling for Directed Self‐Erasing Information Transfer

open access: yesAdvanced Materials, EarlyView.
An azobenzene‐based material with unprecedented light‐pumped directional charge‐transfer reminiscent of toppling dominoes is presented. After light‐induced trans→cis forward isomerization, electron hopping occurs in a sequential and propagating manner between the cis isomers along with an electrocatalytic cis→trans backward isomerization.

Probing neutron star physics using accreting neutron stars

open access: yesEPJ Web of Conferences, 2010
We give an obervational overview of the accreting neutron stars systems as probes of neutron star physics. In particular we focus on the results obtained from the periodic timing of accreting millisecond X-ray pulsars in outburst and from the ...

Unveiling Low-frequency Eclipses in Spider Millisecond Pulsars Using Wideband GMRT Observations

open access: yesThe Astrophysical Journal
Eclipses of radio emission have been reported for ∼58 spider millisecond pulsars (MSPs), of which only around 19% have been extensively studied. Such studies at low frequencies are crucial for probing the properties of the eclipse medium.

10-millisecond Computing

open access: yes, 2016
Despite computation becomes much complex on data with an unprecedented scale, we argue computers or smart devices should and will consistently provide information and knowledge to human being in the order of a few tens milliseconds. We coin a new term 10-millisecond computing to call attention to this class of workloads. 10-millisecond computing raises

The Origin of Millisecond Pulsars [PDF]

open access: yesInternational Astronomical Union Colloquium, 1996
AbstractAccording to the standard model, millisecond pulsars are the descendants of low-mass X-ray binaries (LMXB). The importance of this formation route has, however, been questioned by several authors on different grounds. This paper critically reviews the arguments and assumptions underlying the standard model.
