Acknowledgements I would like to thank the various company managers who participated in the surveys of Yorkshire & Humberside and Northern Ireland. Abstract Multinational enterprises occupy a prominent position in most UK regional economies. The contribution of these firms to employment and growth in the host region will be enhanced if they purchase material inputs from local firms ('local sour...

Around 10% of deep inelastic scattering (DIS) events observed at HERA at small value of the Bjorken variable x are diffractive events [1, 2], when the incoming proton stays intact losing only a small fraction xIP of its initial momentum. A large rapidity gap is formed between the scattered proton (or its low mass excitation) and the diffractive system. The ratio of diffractive to total DIS cros...

Ordered mesoporous tungsten-doped MoO(2) was synthesized by a nanocasting method. The Li storage performance of mesoporous MoO(2) is significantly improved by tungsten doping, which exhibits a reversible capacity of 700 mA h g(-1), better cycling and rate performance. This material combines the advantages of the high theoretical capacity of MoO(2) and the better electroactivity of WO(2).

The most important advantage of an economic order quantity (EOQ) system is its ability to handle the unexpected demand. A model for comparing the inventory costs of purchasing under the EOQ system and the just-in-time (JIT) order purchasing system in existing literature concluded that JIT purchasing was virtually always the preferable inventory ordering system. By expanding the classical EOQ mo...

Previous studies of causal learning heavily focused on binary outcomes; little is known about causal learning with continuous outcomes. The present paper proposes a qualitative extension of the causal power theory to the situation where a binary cause influences a continuous effect, and induces causal power under various ceiling situations with the continuous outcomes. To test the predictions, ...

In this paper a novel hierarchical DfT methodology is presented which is targeted to improve the delay fault testability for external testing and scanbased BIST. After the partitioning of the design into high frequency macros, the analysis for delay fault testability already starts in parallel with the implementation at the macro level. A specification is generated for each macro that defines t...

This paper examines how business investment responded to temporary partial expensing, first enacted in 2002 and expanded in 2003. In principle, partial expensing boosted the incentive to invest which should have had a discernable impact on spending. However, the tax changes did not occur in a vacuum, so it is challenging to isolate their impact. Our empirical approach exploits a feature of the ...

Motivated by some previous work on fermions on random lattices and by suggestions that impurities could trigger parity breaking in 2d crystals, we have analyzed the spectrum of the Dirac equation on a two dimensional square lattice where sites have been removed randomly — a doped lattice. We have found that the system is well described by a sine-Gordon action. The solitons of this model are the...

Population proteomics has a great potential to address evolutionary and ecological questions, but its use in wild populations of non-model organisms is hampered by uncontrolled sources of variation. Here we compare the response to temperature extremes of two geographically distant populations of a diving beetle species (Agabus ramblae) using 2-D DIGE. After one week of acclimation in the labora...

We study the problem of determining the complexity of optimal comparison-based in-place sorting when the key length, k, is not a constant. We present the first algorithm for lexicographically sorting n keys in O(nk+n log n) time using O(1) auxiliary data locations, which is simultaneously optimal in time and space.
