GWTC-2.1: Deep extended catalog of compact binary coalescences observed by LIGO and Virgo during the first half of the third observing run

“…We also expand the population of binaries with significantly asymmetric mass ratios reported in GWTC-2 by an additional two events (the mass ratio is less than 0.65 and 0.44 at 90% probability for GW190403_051519 and GW190917_114630 respectively), and find that two of the eight new events have effective inspiral spins χ eff > 0 (at 90% credibility), while no binary is consistent with χ eff < 0 at the same significance. …”

“…The data are consistent with receiving contributions from a mixture of Λ resonances with different spin-parity quantum numbers. The angular coefficients show a pattern of vector-axial vector interference that is a characteristic of the type of flavour-changing neutral-current transition relevant for these decays.…”

Synthesis and characterization of reduced graphene oxide-based composites by Wu, Shixin

Magnetic levitation using neodymium magnets for vertical axis wind turbine (VAWT) II by Lai, Chunji

“…This project involved the design and fabrication of a test model vertical axis wind turbine, however as this experiment was carried out indoor without any wind condition, the author used a dc motor to simulate the wind required to spin the turbine. The advantage of this motor allows the author some control over the speed of the turbine. …”

Rapid process modeling of the aerosol jet printing based on gaussian process regression with latin hypercube sampling by Zhang, Haining, Moon, Seung Ki, Ngo, T. H., Tou, J., Bin Mohamed Yusoff, M. A.

“…Hence, it is necessary to develop a small data set based machine learning approach to model relationship between the process parameters and the line morphology. In this paper, we propose a rapid process modeling method for AJP process and consider sheath gas flow rate, carrier gas flow rate, stage speed as AJP process parameters, and line width and line roughness as the line morphology. …”

Neutron emission studies from miniature and medium size plasma focus device by Singh, Rajdeep Raweet.

“…Although dense plasma focus devices have attracted the attention of scientific community since 1960’s as a copious source of fusion neutrons but in the recent years owing to spin-off in the applications of compact and portable table top neutron sources in wider domain, like noninvasive interrogation of explosives and narcotic drugs (by using Pulsed Fast/Thermal Neutron Analysis (PFTNA) technique), dark matter research, radioisotope production, medical neutron therapy and soil humidity measurements, there has been renewed interest across the globe for the development of sub-kilojoule range, low energy small plasma focus device (hereafter called ‘Miniature Plasma Focus i.e. …”

An exploratory study for a new method to search for heavy neutrinos with data at the Large Hadron Collider (LHC) by Tan, Cherlene Shu Ning

“…Till this date, all neutrinos observed are left-handed, rotating clockwise with respect to the direction of motion while the corresponding antineutrinos are right-handed, spinning counterclockwise. However, the fact that neutrinos have mass and spin implies that right handed neutrinos and their corresponding left-handed antineutrinos may exist and have differing properties from their chiral counterparts. …”
