A bright millisecond-duration radio burst from a Galactic magnetar

Nature, 2020
Magnetars are highly magnetized young neutron stars that occasionally produce enormous bursts and flares of X-rays and γ-rays1. Of the approximately thirty magnetars currently known in our Galaxy and the Magellanic Clouds, five have exhibited transient ...

Catalyzer: Sub-millisecond Startup for Serverless Computing with Initialization-less Booting

International Conference on Architectural Support for Programming Languages and Operating Systems, 2020
Serverless computing promises cost-efficiency and elasticity for high-productive software development. To achieve this, the serverless sandbox system must address two challenges: strong isolation between function instances, and low startup latency to ...

Relativistic Shapiro delay measurements of an extremely massive millisecond pulsar

Nature Astronomy, 2019
Despite its importance to our understanding of physics at supranuclear densities, the equation of state (EoS) of matter deep within neutron stars remains poorly understood. Millisecond pulsars (MSPs) are among the most useful astrophysical objects in the

Nanosecond-millisecond combined pulse laser drilling of alumina ceramic.

Optics Letters, 2020
A nanosecond-millisecond combined pulse laser (CPL) drilling method was proposed for drilling alumina ceramic. The total energy consumption of the CPL drilling was 1/7 of that of a conventional millisecond laser, and the drilling quality was better.

Reconfigurable nanophotonic silicon probes for sub-millisecond deep-brain optical stimulation

Nature Biomedical Engineering, 2018
The use of nanophotonics to rapidly and precisely reconfigure light beams for the optical stimulation of neurons in vivo has remained elusive. Here we report the design and fabrication of an implantable silicon-based probe that can switch and route ...

A millisecond pulsar

Nature, 1982
The radio properties of 4C21.53 have been an enigma for many years. First, the object displays interplanetary scintillations (IPS) at 81 MHz, indicating structure smaller than 1 are s, despite its low galactic latitude (−0.3°)1. IPS modulation is rare at low latitudes because of interstellar angular broadening. Second, the source has an extremely steep

A millisecond chronoscope

Journal of the Institution of Electrical Engineers - Part II: Power Engineering, 1947
This paper opens with a discussion of various methods of measuring short time intervals and then proceeds to describe a condenser chronoscope suitable for the measurement of intervals initiated and terminated by momentary or sustained makes or breaks in electrical circuits. The range is from 2 millisec to 1 000 millisec. The voltage on the condenser is

Measuring sub-millisecond delays in spiking activity with millisecond time-bins

Neuroscience Letters, 2009
Recent evidence indicates that sub-millisecond delays in neuronal spiking activity may be relevant for neural coding. Estimates of these delays are usually made from cross-correlation histograms (CCH) binned to 1ms. We investigated the degree to which it is possible to measure delays with sub-millisecond precision when one computes CCHs with bin sizes >

A Millisecond Pulsar in an Eclipsing Binary

Nature, 1988
We report the discovery of a remarkable pulsar with period 1.6 ms, moving in a nearly circular 9.17 hour orbit around a low mass companion star. At an observing frequency of 430 MHz, the pulsar, PSR 1957+20, is eclipsed once each orbit for about 50 minutes.
