Optimal Control Applications and Methods, Volume 47, Issue 2, Page 570-588, March/April 2026.Implicit third‐order Peer two‐step methods that are superconvergent for variable stepsizes have the potential to significantly improve the efficiency of solving large‐scale ODE‐constrained optimal control problems. These include real‐world applications in medical treatment planning for prostate cancer, such as the design of effective three‐dose drug ...

Semantic Interoperability of Sensor Data with Volunteered Geographic Information: A Unified Model
ISPRS International Journal of Geo-Information, 2013 The increasing availability of sensor devices has resulted in important volumes of sensor data, which has raised the issue of making these data fully discoverable and interpretable by applications and end-users. The idea of OGC Sensor Web Enablement (SWE)

Convergent expansions for Random Cluster Model with q>0 on infinite graphs
, 2008 In this paper we extend our previous results on the connectivity functions and pressure of the Random Cluster Model in the highly subcritical phase and in the highly supercritical phase, originally proved only on the cubic lattice $\Z^d$, to a much wider

Clinical and Experimental Dental Research, Volume 12, Issue 1, February 2026.ABSTRACT Background The articular eminence is essential for the proper functioning of the temporomandibular joint (TMJ), guiding the movement of the mandibular condyle along its posterior slope. Changes in the inclination of the articular eminence (AEI) can occur as a result of tooth loss or aging.

Volunteered and crowdsourced geographic information: the OpenStreetMap project
Journal of Spatial Information Science, 2020 Advancements in technology over the last two decades have changed how spatial data are created and used. In particular, in the last decade, volunteered geographic information (VGI), i.e., the crowdsourcing of geographic information, has revolutionized ...

Mapping Our Cities for All: A participatory baseline of business accessibility in Canada
Canadian Geographies / Géographies canadiennes, Volume 70, Issue 1, Spring / printemps 2026.Abstract Canada has committed to eliminating accessibility barriers by 2040, yet municipalities lack clear, comparable evidence on where building access breaks down. To address this gap, we set out to produce and test a participatory, city‐scale method to measure building accessibility of businesses. We report results from Mapping Our Cities for All, a

Note on resonance varieties [PDF]
, 2011 We study the irreducibility of resonance varieties of graded rings over an exterior algebra E with particular attention to Orlik-Solomon algebras. We prove that for a stable monomial ideal in E the first resonance variety is irreducible. If J is an Orlik-
