Evaluating the effectiveness of virtual environment displays for displaying 3D models and tasks in construction [PDF]

open access: yes, 2004
Conventionally, 2D paper-based CAD drawings are mainly used to view, extract, change, and exchange project information. This may lead to potential design and constructability conflicts.

Ionic Gating of Liquid‐Crystal‐Like Pteridine Assemblies Enables Tunable Light Scattering

open access: yesAdvanced Materials, EarlyView.
Tunable optical properties emerge through developmentally regulated ionic gating, which transforms disordered, ultraviolet (UV)‐absorbing organelles into concentrically ordered, liquid‐crystal‐like light scatterers. By integrating analyses of pteridine composition, potassium‐dependent assembly, hierarchical ultrastructure, and optical behavior, the ...

Parity‐Dependent THz Harmonic Generation in Electrically Pumped Micro‐Lasers Exploiting Topological Insulator–Metamaterial Gratings

open access: yesAdvanced Materials, EarlyView.
Topological insulator–metamaterials integrated with electrically driven terahertz quantum cascade lasers enable parity‐dependent harmonic generation. Bulk‐dominated Bi2Se3 favors third‐harmonic emission at 9.96 THz, whereas topological‐surface‐state‐dominated Bi2Se3, Bi2Te3, and (Bi,Sb)2Te3 generate strong second harmonics near 6.5 THz.

Virtual mentor: An innovation in student support [PDF]

open access: yes, 2008
Peer mentoring is well established means of support for first year students (Farrell et al. 2004, Green, 2007) which increases student retention and engagement at a relatively low cost (Boud et al, 2001; Hodges and White, 2001). Many of the existing peer
