Oxygen‐Controlled Structural and Defect Engineering of Magnetron‐Sputtered ZnO Thin Films for Photosensing

open access: yesAdvanced Materials Interfaces, EarlyView.
Zinc oxide thin films are engineered by controlling oxygen flow and nominal partial pressure during growth to tune atomic‐scale defects and crystallographic texture that limit device performance. By balancing competing defects, the films achieve improved preferential c‐axis orientation and enhanced ultraviolet photoresponse.

Webs of Relationships: Pedagogies of Citizenship and Modalities of Settlement for “Muslims” in Canada

open access: yesLateral, 2019
Immigrants to Canada must pass a set of pedagogical gate-keeping exercises that compel settler socio-spatial relations to allow them to come into the fort of the nation-state as neoliberal multicultural subjects.

Programmable Variable‐Stiffness Multilayer Elastomer Composites With High‐Aspect‐Ratio Low‐Melting‐Point Alloy Inclusions

open access: yesAdvanced Materials Technologies, EarlyView.
High‐aspect‐ratio low‐melting‐point alloy inclusions are embedded within multilayer silicone laminates to create thermally programmable stiffness. Sequential activation of alloy‐rich layers produces four distinct mechanical states and reconfigures tendon‐driven actuator trajectories under the same load.

Theorizing Socio-Spatial Relations.

open access: yes, 2008
Lively debates on the spatiality of social relations occur regularly in the social sciences. However, these debates often run their course without major impact on empirical inquiries into matters spatial, especially where they appear too abstract ...

Role of features and second-order spatial relations in face discrimination, face recognition, and individual face skills: behavioral and functional magnetic resonance imaging data [PDF]

open access: yes, 2007
We compared the contribution of featural information and second-order spatial-relations (spacing between features) in face processing. A fully factorial design had 'features' (eyes, mouth, nose) the same or different across two successive displays, while

A Constraint‐Based Analytical Framework for Design‐Space Analysis and Material Screening of Tubular Multilayer Dielectric Elastomer Pumps for Extracorporeal Circulatory Applications

open access: yesAdvanced Materials Technologies, EarlyView.
A constraint‐based analytical framework maps the coupled effects of material properties, structural parameters, and operating conditions in tubular dielectric elastomer pumps for extracorporeal circulatory applications. The approach defines performance boundaries through mechanical, electrical, and hydraulic constraints and identifies feasible design ...

CONTAINMENT and CONTACT image schemas in Spanish-English bilingual children’s speech: A case study

open access: yesCultura, Lenguaje y Representación, 2020
English necessitates a linguistic distinction when coding for spatial relations that Spanish does not necessarily make: that of differentiating between CONTACT and CONTAINMENT.

Topological relations between spherical spatial regions with holes

open access: yesInternational Journal of Digital Earth, 2020
There is growing interest in globally modelling the entire planet. Although topological relations between spherical simple regions and topological relations between regions with holes in the plane have been investigated, few studies have focused on the ...

Topological spatial relations for circular spatially extended points: an overview

open access: yes, 2010
Spatial relations between geographical objects include topological spatial relations, that are relations that are preserved under continuous transformations of the space, such as rotation or scaling.
