One of the most difficult challenges of structural analysis is to determine the relative stereochemistry of two asymmetrically substituted centers in an acyclic system. Mass spectrometry has long been known (although perhaps not widely recognized) to have the capacity to accomplish this. The subject has been reviewed, most recently a decade ago (1–3). In the intervening time, in...

The division problem consists of allocating a given amount of an homogeneous and perfectly divisible good among a group of agents with single-peaked preferences on the set of their potential shares. A rule proposes a vector of shares for each division problem. The literature has implicitly assumed that agents will …nd acceptable any share they are assigned to. In this paper we consider the divi...

The UK waste strategy is based upon the central concept of the hierarchy of preferable options for the treatment and disposal of waste. Minimisation is placed at the top of the hierarchy and the Government seeks to encourage its uptake by industry and commerce as well as householders. It has been accepted that previous waste management policy and practice have not delivered the hoped for moveme...

Circadian rhythms are endogenous oscillations that occur with a period close to 24 h in nearly all living organisms. These rhythms originate from the negative autoregulation of gene expression. Deterministic models based on such genetic regulatory processes account for the occurrence of circadian rhythms in constant environmental conditions (e.g., constant darkness), for entrainment of these rh...

An X-band Traveling wave Deflector mode cavity (XTD) has been developed at Radiabeam Technologies to perform longitudinal characterization of the subpicosecond ultra-relativistic electron beams. The device is optimized for the 100 MeV electron beam parameters at the Accelerator Test Facility (ATF) at Brookhaven National Laboratory, and is scalable to higher energies. An XTD is designed to opera...

The involvement of shear stress in the pathogenesis of vascular disease has motivated efforts to define the endothelial cell response to applied shear stress in vitro. A central question has been the mechanisms by which endothelial cells perceive and respond to changes in fluid flow. We have utilized cDNA microarrays to characterize the immediate/early genomic response to applied laminar shear ...

There remains limited evidence regarding surveillance and management of small abdominal aortic aneurysm (AAA) (males <5.5 cm women <5.0 cm) within those ≥80 years age. This review offers a unique experience 17 analysis single consultant practice in stable population (350,000), on AAA at typical District General Hospital the UK, prompted by current suggestions to consider discontinuing ≥85 age w...
