A hulk is a ship that is afloat, but incapable of going to sea. Although sometimes used to describe a ship that has been launched but not completed, the term most often refers to an old ship that has had its rigging and/or internal equipment removed, retaining only its flotational qualities. The term "hulk" can also be used to refer to an abandoned wreck or shell.
Originally, a hulk (sometimes spelled "holk") was a type of medieval sea craft somewhat similar to a cog and a technological precedent of the carrack and caravel.

Sic is a Latin word meaning "thus", "so", "as such", or "in such a manner". In writing, it is placed within the quoted material, in square brackets – or outside it, in regular parentheses – and usually italicized – [sic] – to indicate that an incorrect or unusual spelling, phrase, punctuation, and/or other preceding quoted material has been reproduced verbatim from the quoted original and is not a transcription error.

A postvention is an intervention conducted after a suicide, largely taking the form of support for the bereaved (family, friends, professionals and peers). Family and friends of the suicide victim may be at increased risk of suicide themselves.
The aim is to support and debrief those affected; and reduce the possibility of suicide contagion. Interventions recognize that those bereaved by suicide may be vulnerable to suicidal behaviour themselves and may develop complicated grief reactions.

Doggerland is a name given by archaeologists and geologists to the former landmass in the southern North Sea that connected the island of Great Britain to mainland Europe during and after the last Ice Age. Geological surveys have suggested that Doggerland was a large area of dry land that stretched from Britain's east coast across to the present coast of the Netherlands and the western coasts of Germany and Denmark. The land was likely a rich habitat with human habitation in the Mesolithic period.

In any observed data set or sample there is the possibility, especially with low-probability events and/or small data sets, of a possible event not occurring. Its observed frequency is therefore 0, implying a probability of 0. This is an oversimplification and is often unhelpful, particularly in probability-based machine learning techniques such as artificial neural networks and hidden Markov models. By artificially adjusting the probability of rare (but not impossible) events so those probabilities are not exactly zero, we avoid the zero-frequency problem.

Pinking shears have a utilitarian function for cutting woven cloth. Cloth edges that are unfinished will easily fray, the weave becoming undone and threads pulling out easily. The sawtooth pattern does not prevent the fraying but limits the length of the frayed thread and thus minimizes damage.

Telemedicine is a rapidly developing application of clinical medicine where medical information is transferred through the phone or the Internet and sometimes other networks for the purpose of consulting, and sometimes remote medical procedures or examinations.
Telemedicine may be as simple as two health professionals discussing a case over the telephone, or as complex as using satellite technology and video-conferencing equipment to conduct a real-time consultation between medical specialists in two different countries. Telemedicine generally refers to the use of communications and information technologies for the delivery of clinical care.
