Werner state structure and entanglement classification

We present applications of the representation theory of Lie groups to the analysis of structure and local unitary classification of Werner states, sometimes called the {\em decoherence-free} states, which are states of $n$ quantum bits left unchanged by local transformations that are the same on each particle. We introduce a multiqubit generalization of the singlet state, and a construction that assembles these into Werner states.Comment: 9 pages, 2 figures, minor changes and corrections for version

The role of herbivores as ecosystem engineers in Great Barrier Reef seagrass meadows

Abigail Scott studied how herbivore grazing can modify seagrass meadows in the Great Barrier Reef. She found that herbivores act as ecosystem engineers in these seagrass meadows, particularly green turtles and dugong. Abigail's results will be used to inform seagrass monitoring on the Great Barrier Reef

VA Accountability and Whistleblower Protection Act of 2017

The purpose of this article is to provide an overview of the Department of Veterans Affairs Accountability and Whistleblower Protection Act of 2017 (S.1094). Specifically, this paper explores the law’s journey throughout the American governance system, including the legislative, judicial, and executive branches. This is supplemented by an examination of the core political theories on the bureaucratic institutions that define the policymaking process. The paper analyzes the most complex aspects of the lawmaking process in the context of S. 1094, including the barriers to implementation and claims to its constitutional basis. The objective of this article is to examine the development of this particular law from the perspective of these various institutions of the political system in addition to an evaluation of the way it accomplishes the goals at the heart of this piece of legislation. This analysis is complemented by exploring the role of interest groups, political parties, and unorthodox lawmaking practices

The inquiring sort: ideas and learning in late eighteenth-century Birmingham

The conflicting visions of eighteenth-century society offered by J. C. D. Clark and the historians of the English Enlightenment are here used as a means by which to examine aspects of the public spheres of Birmingham. Whilst it was a town of conviviality and consumption of culture, these activities were suffused with a serious purpose born of religious conviction. The concept of the Inquiring Sort has been developed to describe this aspect of Birmingham Society. A case study has been made of Freemasonry in Birmingham, as an example of a group within the Inquiring Sort. The public sphere of ideas and learning, in which the Inquiring Sort spent leisure time, included lectures, libraries, bookshops and debating societies. The spaces in which they moved, marked both by places of fashionable consumption and places of cultural consumption, have been mapped and their world of books and texts analysed. The role of religious inquiry is a key thread in these areas. The roles played by ideas and learning in three elements of Birmingham industry are examined: gaining skills through the printed word, the marketing of goods and the place of fashion. Knowledge of the self is seen to be key in each case. Religion in eighteenth century Birmingham is explored, focusing particularly on the previously under-researched Established Church there. Finally, the reaction of the Established Church to controversial ideas, particularly to the radical Unitarianism of Joseph Priestly, is analysed. It is argued that disputes over such ideas were central in the development of hostilities in the town during the 1780s, which culminated in the Church and King riot of 1791
