Smart, Bio‐Inspired Polymers and Bio‐Based Molecules Modified by Zwitterionic Motifs to Design Next‐Generation Materials for Medical Applications

Advanced Functional Materials, EarlyView.
Bio‐based and (semi‐)synthetic zwitterion‐modified novel materials and fully synthetic next‐generation alternatives show the importance of material design for different biomedical applications. The zwitterionic character affects the physiochemical behavior of the material and deepens the understanding of chemical interaction mechanisms within the ...

Geometry‐Dependent Adhesion in Transparent Monodomain Liquid Crystal Elastomers

Advanced Functional Materials, EarlyView.
Liquid Crystal Elastomers (LCEs) are emerging as exciting pressure‐sensitive adhesives. We examine adhesion in chemically identical elastomer films, exploring the influence of geometry (director orientation) and phase (nematic or isotropic). We demonstrate the potential of these aligned films as transparent, tunable, broad‐temperature‐range smart ...

Spatially Tailorable Liquid Crystalline Elastomer Alignment During Digital Light Process 3D Printing

Advanced Functional Materials, EarlyView.
Here, we report the fabrication of 3D printable liquid crystalline elastomer (LCE) structures with spatially tailorable alignment domains within the same layer. This work addresses the long‐standing challenge of preparing complex 3D LCE architectures with patterned functional domains to achieve nonlinear deformations. Fabrication of multi‐domains in 3D

Admission of Deaf Soldiers to the Military: Rethinking the Undifferentiated Soldier Paradigm [PDF]

, 2018
Keith Nolan, a deaf man with undergraduate and graduate degrees, asked to be admitted to military training to become a uniformed American soldier. The military said no, and the issue was joined. Nolan’s application presents the Department of Defense (DOD)

Lithium Intercalation in the Anisotropic Van Der Waals Semiconductor CrSBr

Advanced Functional Materials, EarlyView.
We report the lithium intercalation in the layered van der Waals crystal CrSBr, revealing strongly anisotropic ion‐migration dynamics. Optical and electrical characterization of exfoliated CrSBr shows lithium diffusion coefficients that differ by more than an order of magnitude along a‐ and b‐directions, consistent with molecular dynamics simulations ...

“They are now community police”: Negotiating the boundaries and nature of the Government in South Sudan through the identity of militarised cattle-keepers [PDF]

, 2015
Armed, cattle-herding men in Africa are often assumed to be at a relational and spatial distance from the ‘legitimate’ armed forces of the government. The vision constructed of the South Sudanese government in 2005 by the Comprehensive Peace Agreement ...

Meta‐Rod Mechanical Metamaterials With Programmable Reconfiguration

Advanced Functional Materials, EarlyView.
Existing mechanical metamaterials achieve programmable large deformations in planar square or cubic configurations, restricted by required complex boundary conditions. This research proposes a 1D metamaterial, Meta‐rod, with linear, bending, twisting, area, and volume deformation modes.

Comparison of semi and fully automated artificial intelligence driven softwares and manual system for cephalometric analysis

BMC Medical Informatics and Decision Making
Background Cephalometric analysis has been used as one of the main tools for orthodontic diagnosis and treatment planning. The analysis can be performed manually on acetate tracing sheets, digitally by manual selection of landmarks or by recently ...

Strategic Interests in Australian Defence Policy: Some Historical and Methodological Reflections [PDF]

, 2015
The first, and often the hardest, step in any defence policy is to define strategic objectives—what we want our armed forces to be able to do. This is especially hard for a country like Australia, because most of the circumstances in which we would rely ...
