The point of maximum curvature as a marker for physiological time series

We present a geometric analysis of the model of Stirling. In particular we analyze the curvature of a heart rate time series in response to a step like increment in the exercise intensity. We present solutions for the point of maximum curvature which can be used as a marker of physiological interest. This marker defines the point after which the heart rate no longer continues to rapidly rise and instead follows either a steady state or slow rise. These methods are then applied to find analytic solutions for a mono exponential model which is commonly used in the literature to model the response to a moderate exercise intensity. Numerical solutions are then found for the full model and parameter values presented in Stirling

Anomalous quartic WWgamma gamma, ZZgamma gamma, and trilinear WWgamma couplings in two-photon processes at high luminosity at the LHC

We study the W/Z pair production via two-photon exchange at the LHC and give the sensitivities on trilinear and quartic gauge anomalous couplings between photons and W/Z bosons for an integrated luminosity of 30 and 200 fb^{-1}. For simplicity and to obtain lower backgrounds, only the leptonic decays of the electroweak bosons are considered.Comment: 22 pages, 17 figures, sumitted to Phys. Rev.

Beyond agriculture: alternative geographies of rural land investment and place effects across the United Kingdom

Global land ownership patterns have been shifting in recent decades, as institutional and non-traditional investors redirect capital into rural areas. Such investment is a stimulating alternative for innovative profit-driven land uses that move beyond agriculture. This paper explores how ‘new money’ economies have created place effects in three rural case studies across the United Kingdom, through concepts of built, natural, social, and economic capital. The case studies are informed by secondary research, site visits, and interviews, providing snapshots of investment impact. They represent diverse transformations in rural land use via new forms of direct investment, active investment, and processes of financing rather than financialisation, with distinct spatial and temporal characteristics. The case studies include new wine production in Kent, England; transforming the Menie Estate into Trump International Golf Links Scotland (TIGLS); and farm diversification in Northern Ireland. The conclusions tell three investment stories, where place effects reflect the dichotomies, contestation, and symbiosis between investors and local contexts. New land uses create place effects where economic potential often conflicts with natural capital impacts, although they foster knowledge creation and exchange. The underlying values of the investors and their navigation of local politics also have key roles to play in shaping the built, natural, social, and economic place effects

ArcGIS V.10 landslide susceptibility data mining add-in tool integrating data mining and GIS techniques to model landslide susceptibility

Landslide susceptibility modeling is an essential early step towards managing landslide risk. A minimum of $4.8 million is lost due to landslide related damages every year in Illawara region of Australia. At present, Data mining and knowledge discovery techniques are becoming popular in building landslide susceptibility models due to their enhanced predictive performances. Until now, the lack of tools to undertake data extraction and making the predictions have limited the applicability of this novel technique in landslide model building. This paper discusses the development of the LSDM (Landslide Susceptibility Data Mining) toolbar which was designed to utilize machine learning techniques within a GIS environment by coupling GIS and data mining software (See5) capabilities. The software development kit available with ArcGIS v.10 has been utilized in developing the toolbar add-in. The fundamental tasks; data preparation, model optimizing, derivation of decision trees, predictions and validation are all performed using the individual controls available in the toolbar. This tool automates the entire model building process and in preparation of training data and producing outcomes that are compliant with both national and international Landslide Risk management guidelines

Sydney Basin Landslide Susceptibility, NSW, Australia

University of Wollongong GIS-based Landslide Inventory has been expanded to facilitate reliable modeling of landslide susceptibility and hazard zonation over the wider Sydney Basin area. Landslide inventory development is underway after designing a state of the art inventory structure following a comprehensive international literature review. The alphanumerical as well as spatial data bases of landslides have been updated after field verification of landslides in Sydney and Newcastle as the stepping stone for the wider Sydney Basin area landslide susceptibility model development. In the lead up to this, landslide susceptibility modeling in two smaller sub-regions of Sydney (Wollongong Local Government Area and the Picton area) has been undertaken by the Landslide Research Team at the University of Wollongong. In tandem with the development of the landslide inventory, new tools and methods have been developed to aid application of Data Mining techniques within a GIS framework to obtain more reliable modeling, analysis and synthesis. The main aim of this paper is to report the latest advances in landslide inventory development, preparation and compilation of data for the modeling work

Housing Access and Affordability in Rural England: Tackling Inequalities Through Upstream Reform or Downstream Intervention?

A combination of development constraint, low wages in seasonal employment and market intrusion by more affluent households generates housing access and affordability difficulties in many rural amenity areas. In response, residents’ groups and public planners have sometimes sought to prioritise ‘local needs’, restricting the occupancy of new housing to key workers or others deemed ‘local’. Drawing on examples from England, this paper illustrates how these down-stream interventions are often rendered ineffective by the upstream and structural drivers of housing access inequality, revealing a need for up-stream reforms focused on community control of land and the tax treatment of housing
