Design and evaluation of a scalable Internet of Things backend for smart ports

Software: Practice and Experience, Volume 51, Issue 7, Page 1557-1579, July 2021., 2021
Abstract Internet of Things (IoT) technologies, when adequately integrated, cater for logistics optimisation and operations' environmental impact monitoring, both key aspects for today's EU ports management. This article presents Obelisk, a scalable and multi‐tenant cloud‐based IoT integration platform used in the EU H2020 PortForward project.

GMRT Discovery of A Millisecond Pulsar in a Very Eccentric Binary System [PDF]

, 2004
We report the discovery of the binary millisecond pulsar J0514-4002A, which is the first known pulsar in the globular cluster NGC 1851 and the first pulsar discovered using the Giant Metrewave Radio Telescope (GMRT). The pulsar has a rotational period of

A NICER View of the Nearest and Brightest Millisecond Pulsar: PSR J0437–4715 [PDF]

Astrophysical Journal Letters
We report Bayesian inference of the mass, radius, and hot X-ray emitting region properties—using data from the Neutron Star Interior Composition ExploreR (NICER)—for the brightest rotation-powered millisecond X-ray pulsar, PSR J0437−4715. Our modeling is

An Extremely Low-mass He White Dwarf Orbiting the Millisecond Pulsar J1342+2822B in the Globular Cluster M3 [PDF]

Astrophysical Journal, 2019
We report on the discovery of the companion star to the millisecond pulsar J1342+2822B in the globular cluster M3. We exploited a combination of near-ultraviolet and optical observations acquired with the Hubble Space Telescope in order to search for the

Neutron star collisions and gravitational waves

Astronomische Nachrichten, Volume 342, Issue 5, Page 788-798, June 2021., 2021
Abstract The long‐awaited detection of a gravitational wave from the merger of a binary neutron star in August 2017 (GW170817) marked the beginning of the new field of multi‐messenger gravitational wave astronomy. By exploiting the extracted tidal deformations of the two neutron stars from the late inspiral phase of GW170817, it was possible to ...

The rise of single‐cell proteomics

Analytical Science Advances, Volume 2, Issue 3-4, Page 84-94, April 2021., 2021
Abstract Mass spectrometry‐based proteomics comprehensively defines proteome expression patterns in thousands of cells majorly contributing to our current understanding of many biological processes. More recently, single‐cell transcriptome and genome studies, however, have demonstrated overwhelming heterogeneity of tissues and cellular subpopulations ...

The Multipolar Magnetic Field of the Millisecond Pulsar PSR J0030+0451

, 2020
Modeling of the NICER X-ray waveform of the pulsar PSR J0030+0451, aimed at constraining the neutron star mass and radius, has inferred surface hot spots (the magnetic polar caps) that imply significantly nondipolar magnetic fields.

Pressure Balance and Intrabinary Shock Stability in Rotation-powered-state Redback and Transitional Millisecond Pulsar Binary Systems [PDF]

Astrophysical Journal, 2018
A number of low-mass millisecond pulsar (MSP) binaries in their rotation-powered state exhibit double-peaked X-ray orbital modulation centered at inferior pulsar conjunction.

Millisecond Pulsar Velocities [PDF]

, 1998
We present improved timing parameters for 13 millisecond pulsars (MSPs) including 9 new proper motion measurements. These new proper motions bring to 23 the number of MSPs with measured transverse velocities.

Mode Changing and Giant Pulses in the Millisecond Pulsar PSR B1957+20 [PDF]

Astrophysical Journal, 2018
Many radio pulsars have stable pulse profiles, but some exhibit mode changing where the profile switches between two or more quasi-stable modes of emission.
