Electrotherapies for Glioblastoma
Advanced Science, Volume 8, Issue 18, September 22, 2021., 2021 Electrotherapy uses electric fields to target various biological mechanisms for therapeutic outcomes. The current state of intermediate frequency electric fields including tumour‐treating fields, and reversible/irreversible electroporation are discussed in both pre‐clinical and clinical models of glioblastoma.

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

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 ...

Optical pulsations from a transitional millisecond pulsar [PDF]
, 2017 Weakly magnetic, millisecond spinning neutron stars attain their very fast rotation through a 1E8-1E9 yr long phase during which they undergo disk-accretion of matter from a low mass companion star. They can be detected as accretion-powered millisecond X-

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.

Binary and Millisecond Pulsars [PDF]
Annual Review of Astronomy and Astrophysics, 1994 Most of the ~600 known pulsars are single and located in the disk of our Galaxy. There is circumstantial evidence that the pulsars in this majority are created in supernova (SN) explosions, by the collapse of the cores of massive stars (initial mass M_i ≳ M_(cr) ≃ 8 M_⊙). One is created roughly every 100 y in the Galaxy.

A Survey for Millisecond Pulsars [PDF]
The Astrophysical Journal, 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 bandwidth.
