Swift as an Arrow

Quantum Measurement as an Arrow of Time

In this essay, I wish to provide some reasons to take seriously the possibility that physics is neither symmetric under time-reversal nor deterministic. I want to aim for accessibility to readers outside physics, so I include some material that will be introductory for specialists, I hope at least to offer an unorthodox perspective. I will start with an examination of how the formalism of quant...

Time flies like an arrow

Dr Yorick Wilks There is an ancient Chinese curse is reader in theoretical that dooms its recipients to live linguistics, the in an interesting age, and by those University of Essex standards machine translation workers are at present having a bad time. Things are interesting at the moment because there are conflicting claims in the air about how to do machine translation, and whether it can be...

Plugging a Space Leak with an Arrow

The implementation of conceptually continuous signals in functional reactive programming (FRP) is studied in detail. We show that recursive signals in standard implementations using streams and continuations lead to potentially serious time and space leaks under conventional call-by-need evaluation. However, by moving to the level of signal functions, and structuring the design around arrows, t...

Repositories: What's the target? An ARROW Perspective

The key observation about institutional research repositories is that they are under-used. This paper looks at why take-up has been slow, and what might encourage researchers to use these facilities. This paper surveys the evolution of practice and rationale for the institutional research repository, looks at existing use studies and opinion surveys of users, and examines ways in which universi...
