Almost two decades into the new millennium, it is unlikely that the use of digital technologies will slow in any significant way, particularly in the public sector. As local and...
SpecAugment: A Simple Data Augmentation Method for Automatic Speech Recognition
We present SpecAugment, a simple data augmentation method for speech\nrecognition. SpecAugment is applied directly to the feature inputs of a neural\nnetwork (i.e., filter bank ...
Clonal Hematopoiesis and Blood-Cancer Risk Inferred from Blood DNA Sequence
Clonal hematopoiesis with somatic mutations is readily detected by means of DNA sequencing, is increasingly common as people age, and is associated with increased risks of hemat...
Belief in the law of small numbers.
Reports that people have erroneous intuitions about the laws of chance. In particular, they regard a sample randomly drawn from a population as highly representative, I.e., simi...
Dynamical matrices, Born effective charges, dielectric permittivity tensors, and interatomic force constants from density-functional perturbation theory
Starting from the knowledge of first-order changes of wave functions and density with respect to small atomic displacements or infinitesimal homogeneous electric fields within t...
On the Non-Orthogonality Problem Connected with the Use of Atomic Wave Functions in the Theory of Molecules and Crystals
The treatment of molecules and crystals by the Heitler-London method or by the collective electron model can be based on the atomic orbitals φμ of the system. These orbitals are...
What is an adequate sample size? Operationalising data saturation for theory-based interview studies
In interview studies, sample size is often justified by interviewing participants until reaching 'data saturation'. However, there is no agreed method of establishing this. We p...
Similarity Search in High Dimensions via Hashing
The nearest- or near-neighbor query problems arise in a large variety of database applications, usually in the context of similarity searching. Of late, there has been increasin...
Two Agency-Cost Explanations of Dividends
The economic literature about dividends usually assumes that managers are perfect agents of investors, and it seeks to determine why these agents pay dividends. Other literature...
