Featherweight Go
(2020-11-13)
We describe a design for generics in Go inspired by previous work on Featherweight Java by Igarashi, Pierce, and Wadler. Whereas subtyping in Java is nominal, in Go it is structural, and whereas generics in Java are defined ...
A Minimum Dilution Scenario for Supernovae and Consequences for Extremely Metal-Poor Stars
(2020-11-01)
To date no metal-free stars have been identified by direct observations. The most common method of constraining their properties is searching the spectra of the most metal-poor stars for the chemical elements created in ...
Constraining Nucleosynthesis in Two CEMP Progenitors Using Fluorine
(2020-11-01)
We present new fluorine abundance estimations in two carbon enhanced metal-poor (CEMP) stars, HE 1429-0551 and HE 1305+0007. HE 1429-0551 is also enriched in slow neutron-capture process (s-process) elements, a CEMP-s, and ...
Review on 3D printing: Fight against COVID-19
(2020-10-22)
The outbreak of Coronavirus in 2019 (COVID-19) caused by the SARS-CoV-2 virus and its pandemic effects have created a demand for essential medicine equipment. To date, there are no specific, clinically effective licensed ...
Illegal Logging Detection Based on Acoustic Surveillance of Forest
(2020-10-21)
In this article, we present a framework for automatic detection of logging activity in forests using audio recordings. The framework was evaluated in terms of logging detection classification performance and various widely ...
3D printing of PEEK–cHAp scaffold for medical bone implant
(2020-10-21)
The major drawback associated with PEEK implants is their biologically inert surface, which caused unsatisfactory cellular response and poor adhesion between the implants and surrounding soft tissues against proper bone ...
Fixed pattern noise reduction and linearity improvement in time-mode CMOS image sensors
(2020-10-20)
In the paper, a digital clock stopping technique for gain and offset correction in time-mode analog-to-digital converters (ADCs) has been proposed. The technique is dedicated to imagers with massively parallel image ...
Effect of injection strategies on a single-fuel RCCI combustion fueled with isobutanol/isobutanol + DTBP blends
(2020-10-15)
In recent years, improved combustion controllability through in-cylinder reactivity stratification by using two different fuels have led to introduction of dual-fuel reactivity controlled compression ignition (RCCI) strategy. ...
A novel treatment strategy for preterm birth: Intra-vaginal progesterone-loaded fibrous patches
(2020-10-15)
Progesterone-loaded poly(lactic) acid fibrous polymeric patches were produced using electrospinning and pressurized gyration for intra-vaginal application to prevent preterm birth. The patches were intravaginally inserted ...
Link between radio-loud AGNs and host-galaxy shape
(2020-10-15)
The morphology of quiescent galaxies has been found to be correlated with the activity of their central super massive black hole. In this work, we use data from the first data release of the LOFAR Two$-$Metre Sky Survey ...
