Approximating Holant problems by winding

We give an FPRAS for Holant problems with parity constraints and not-all-equal constraints, a generalisation of the problem of counting sink-free-orientations. The approach combines a sampler for near-assignments of "windable" functions -- using the cycle-unwinding canonical paths technique of Jerrum and Sinclair -- with a bound on the weight of near-assignments. The proof generalises to a larger class of Holant problems; we characterise this class and show that it cannot be extended by expressibility reductions. We then ask whether windability is equivalent to expressibility by matchings circuits (an analogue of matchgates), and give a positive answer for functions of arity three

UCL (University College London) Libraries Masterplan: Masterplanning Report

BDP were appointed to undertake a Masterplan for the UCL Main Library and the UCL Science Library and to identify how these buildings could be re-ordered to significantly improve the quality of the library environment and to facilitate the delivery of library services. An initial brief was agreed with UCL’s Estates Management Committee and a Masterplan Steering Group established including academic representatives, library staff and design consultants. To inform the development of this brief, UCL Library Services undertook a number of consultation exercises with users of the Library; students, academic staff and external users, together with Library staff. A number of visits to exemplar library buildings in the UK and continental Europe were also undertaken to inform the development of options for the buildings. Following the development and review of initial options for both the Main Library and Science Library, it was agreed a further, hypothetical New Build Central Library Option should be reviewed, to accommodate a relocated and consolidated library service encompassing 7 of the 16 existing libraries currently distributed across the UCL Estate

Long Term Mitigation Scenarios: Strategic Options for South Africa

The focus of this document is mitigation: if South Africa takes the decision to mitigate, then this document addresses how to determine the options, the emissions reductions achieved by these options, and the attendant costs of each option. How, then, is South Africa to grow and develop in order to reduce poverty, while at the same time retooling its economy in order to reduce its greenhouse gas emissions
