We present two confirmed wide separation L-dwarf common proper motion companions to nearby stars and one candidate identified from the Two Micron All Sky Survey. Spectral types from optical spectroscopy are L0 V, L2.5 V, and L8 V. Near-infrared low resolution spectra of the companions are provided as well as a grid of known objects spanning M6 V – T dwarfs to support spectral type assignment fo...

A catalog of common-proper-motion (CPM) companions to stars within 67 pc of the Sun is constructed based on the SUPERBLINK proper-motion survey. It contains 1392 CPM pairs with angular separations 30 < ρ < 1800, relative proper motion between the two components less than 25 mas yr, magnitudes and colors of the secondaries consistent with those of dwarfs in the (MV , V − J) diagram. In addition,...

In recent development discourse, much has been debated and written about evidence-based actions, defined as: ‘the application of the best available systematically assembled evidence in setting policy and practice’. Nutrition is clearly not exempt from justifying itself, and it is important that Public Health Nutrition has addressed this in recent issues. Much of our knowledge of ‘what works’ de...

The life of an RNA molecule is complicated. Once a newly synthesized eukaryotic RNA has emerged from the RNA polymerase in the nucleus, it will be processed, spliced, and exported into cytoplasm. In prokaryotes, transcribed RNA is synthesized directly in the cytoplasm. RNA molecules that serve as mRNAs have to be kept devoid of local structures that are inhibitory for ribosome scanning and tran...

The paper concerns the closely related topics of the possibility of machines having identifiable personalities, and the possible future legal responsibilities of machines. As will become clear, I wish to explore these topics in terms which are basically those of computational linguistics; and by ‘machines’ here, I intend software entities, rather than robots, and in particular the sort of softw...
