The search for new physics by the measurement of the 4-jet cross section at LHC and FNAL

We investigate the possibility to look for new physics by the measurement of the 4-jet cross section at LHC and FNAL. In particular, we consider the model with scalar colour octet and the supersymmetric model with R-parity violation. In both models pair produced new particles decay into 2 jets thus leading to 4-jet events. Therefore, the measurement of the distributions of 4-jet differential cross section on the invariant dijet masses allows to look for new physics. The main background comes from standard QCD 4-jet events. We find that at LHC it would be possible to discover scalar colour particles with masses up to 900 Gev and for FNAL the corresponding bound is 175 Gev.Comment: 14 pages, late

Part I: the effects of the nature of respired gases on the pulmonary vascular bed with reference to the effects of carbon dioxide, oxygen and nitrogen; Part II: changes in renal function due to the action of certain drugs upon the hypothalamus

Variations in the amount of antidiuretic hormone secreted from the neurohypophysis are reflected as changes in the rate of urine flow from the kidneys. The evidence has already been discussed in the introduction to this thesis for the belief that the neurohypophysis is innervated from cells in the supraoptic nucleus; and that the integrity of the nervous connections between the supraoptic nucleus and the neurohypophysis is essential for the normal control of the rate of 'urine secretion.Stimuli applied to the supraoptic nucleus, either directly, or indirectly, cause changes in the rate of urine excretion; thus these changes can be used to indicate the state of activity of the supraoptic nuclear cells.The experiments reported in this thesis have lent further support to the view that acetyl choline stimulates the cells of the supraoptic nucleus. The results also give rise to many interesting speculations, the exact origin of which is obscure at present.The supraoptic nucleus is a comparatively easily accessible central synapse, and in recording variations of the rate of urine secretion a reliable index of the state of activity of the cells is present.It is likely that further work on these lines may provide important information as to the behaviour of central synapses

Configurations of Extremal Even Unimodular Lattices

We extend the results of Ozeki on the configurations of extremal even unimodular lattices. Specifically, we show that if L is such a lattice of rank 56, 72, or 96, then L is generated by its minimal-norm vectors.Comment: 8 pages. To appear, International Journal of Number Theor

Modelling and testing of long range battery electric vehicle performance

There are two significant issues facing road transport in the medium to long term: the depletion of cheap oil reserves and the need to reduce carbon emissions. A long term solution for passenger cars could be the introduction of battery electric vehicles (BEVs). However, one of the main problems associated with the current generation of BEVs is their short range relative to conventional internal combustion engine (ICE) cars.To investigate this issue, a long range battery electric vehicle, the UltraCommuter (UC), was constructed by the University of Waikato in partnership with HybridAuto Ltd. This paper describes the development, modelling and testing of the UC and its performance in the 2007 World Solar Challenge.<br /

Writing an accounting or business history: Notes toward a methodology

Historical research in accounting and business includes many subject areas, including the writing of histories of accounting and business firms. Each subject area of historical research must be undertaken by utilizing appropriate research methodology. In this article, a research methodology is presented to assist those interested in writing an accounting or business history

Spin analog of the controlled Josephson charge current

We propose a controlled Josephson spin current across the junction of two non-centrosymmetric superconductors like CePt_3Si. The Josephson spin current arises due to direction dependent tunneling matrix element and different momentum dependent phases of the triplet components of the gap function. Its modulation with the angle \xi between the noncentrosymmetric axes of two superconductors is proportional to \sin \xi. This particular dependence on \xi may find application of the proposed set-up in making a Josephson spin switch.Comment: 4 pages, 1 figure; title is changed; article is rewritte

Levelling Up for health in towns? Development of a new deprivation index: the 'Stronger Towns Index' and its association with self-rated health and migration in England, between 2001 and 2011

Aim: To develop the ‘Stronger Towns Index': a deprivation index that took into account characteristics of areas encompassing towns that may be eligible for redevelopment funding and explore how this index was associated with self-rated health and migration within England between 2001 and 2011. / Subject and methods: All members of the ONS Longitudinal Study in England aged 16 and over in 2001 whose records included a self-rated health response and a valid local authority code. Local authorities in England were ranked using a composite index developed using the five metrics set out in the Stronger Towns Funding: productivity, income, skills, deprivation measures, and the proportion of people living in towns. The index was split into deciles, and logistic regression carried out on the association between decile and self-rated health in 2001 in the main sample (n = 407,878) and decile change and self-rated health in 2011 in a subsample also present in 2011, with migration information (n = 299,008). / Results: There were areas in the lowest deciles of Town Strength who did not receive funding. After multiple adjustment, LS members living in areas with higher deciles were significantly more likely (7% to 38%) to report good health than those in the lowest decile in 2001. Remaining in the same decile between 2001 and 2011 was associated with 7% lower odds of good self-rated health in 2011. / Conclusion: It is important to consider health in towns when allocating funding. Areas in the Midlands may have missed out on funding which might help mitigate poor health

Object orientation without extending Z

The good news of this paper is that without extending Z, we can elegantly specify object-oriented systems, including encapsulation, inheritance and subtype polymorphism (dynamic dispatch). The bad news is that this specification style is rather different to normal Z specifications, more abstract and axiomatic, which means that it is not so well supported by current Z tools such as animators. It also enforces behavioural subtyping, unlike most object-oriented programming languages. This paper explains the proposed style, with examples, and discusses its advantages and disadvantages
