Freedom of information – Challenges and the way forward

open access: yesPacific Journalism Review, 2019
Commentary: While the media has demonstrated that it can cover global and governance issues, it neglects the potential to be a responsible partner, especially in developing countries such as Papua New Guinea and to an extent the Pacific.

Nuclear spin qubits in a trapped-ion quantum computer

open access: yes, 2009
Physical systems must fulfill a number of conditions to qualify as useful quantum bits (qubits) for quantum information processing, including ease of manipulation, long decoherence times, and high fidelity readout operations.

Engineering Deformation and Failure in Diamond Triply Periodic Minimal Surface Lattices via 3D Wall‐Thickness Grading

open access: yesAdvanced Engineering Materials, EarlyView.
The work demonstrates that strategic wall‐thickness grading in diamond triply periodic minimal surface lattices enables precise tuning of deformation and failure behavior under compression. Different gradation patterns guide how and where the structure collapses, improving energy absorption or promoting controlled brittle failure.

Do Freedom of Information Laws Decrease Corruption? [PDF]

open access: yes
It has been argued that greater transparency is needed to reduce corruption. One way of increasing transparency is through the adoption of Freedom of Information (FOI) laws.

3D (Bio) Printing Combined Fiber Fabrication Methods for Tissue Engineering Applications: Possibilities and Limitations

open access: yesAdvanced Functional Materials, EarlyView.
Biofabrication aims at providing innovative technologies and tools for the fabrication of tissue‐like constructs for tissue engineering and regenerative medicine applications. By integrating multiple biofabrication technologies, such as 3D (bio) printing with fiber fabrication methods, it would be more realistic to reconstruct native tissue's ...

Entanglement and interference between different degrees of freedom of photons states

open access: yes, 2008
In this paper, photonic entanglement and interference are described and analyzed with the language of quantum information process. Correspondingly, a photon state involving several degrees of freedom is represented in a new expression based on the ...
