Focal Loss for Dense Object Detection
The highest accuracy object detectors to date are based on a two-stage approach popularized by R-CNN, where a classifier is applied to a sparse set of candidate object locations...

The Astropy Project: Building an Open-science Project and Status of the v2.0 Core Package<sup>*</sup>
Abstract The Astropy Project supports and fosters the development of open-source and openly developed Python packages that provide commonly needed functionality to the astronomi...
A Direct Approach to False Discovery Rates
Summary Multiple-hypothesis testing involves guarding against much more complicated errors than single-hypothesis testing. Whereas we typically control the type I error rate for...
Quantum theory, the Church–Turing principle and the universal quantum computer
It is argued that underlying the Church–Turing hypothesis there is an implicit physical assertion. Here, this assertion is presented explicitly as a physical principle: ‘every f...
The catalytic decomposition of hydrogen peroxide by iron salts
[ Note by Dr. O. H. Wansbrough-Jones —Shortly before Professor Haber died, he gave the manuscript of this paper to Professor Sir William Pope. The final revision for the press h...
VIII. Stability of a viscous liquid contained between two rotating cylinders
In recent years much information has been accumulated about the flow of fluids past solid boundaries. All experiments so far carried out seem to indicate that in all cases stead...
Harmonized guidelines for single-laboratory validation of methods of analysis (IUPAC Technical Report)
Abstract Method validation is one of the measures universally recognized as a necessary part of a comprehensive system of quality assurance in analytical chemistry. In the past,...
The social context of well–being
Large samples of data from the World Values Survey, the US Benchmark Survey and a comparable Canadian survey are used to estimate equations designed to explore the social contex...
The 2dF Galaxy Redshift Survey: spectra and redshifts
The 2dF Galaxy Redshift Survey (2dFGRS) is designed to measure redshifts for approximately 250 000 galaxies. This paper describes the survey design, the spectroscopic observatio...
Worldwide Human Relationships Inferred from Genome-Wide Patterns of Variation
Human genetic diversity is shaped by both demographic and biological factors and has fundamental implications for understanding the genetic basis of diseases. We studied 938 unr...
