Disrupt, Deny, Dismantle: A Special Operations Forces (SOF) Model for Combatting New Terrorism [PDF]

open access: yes, 2016
Terrorism in the new millennium has morphed drastically since the 1970s. The terrorist organizations of today are a hybrid between the insurgent group models of the 1960s and modern terrorist organizations such as Al Qaeda.

Efficient and Robust Heterostructure CeZrOx/NiO‐Ni Inverse Catalyst for Sustainable Photothermal CO2 Methanation

open access: yesAdvanced Science, EarlyView.
A heterostructured CeZrOx/NiO‐Ni inverse catalyst is designed for highly efficient photothermal CO2 methanation under low‐intensity light without auxiliary heating. It achieves 464 mmol·gcat−1·h−1 methane space‐time yield under natural concentrated sunlight, maintains stability over light‐dark cycles and extended air storage, and is scalable to 100 g ...

Bioinspired Adaptive Leg‐Claw Enables Robust Perching and Grasping for UAVs

open access: yesAdvanced Science, EarlyView.
Inspired by owl limb morphology and bat roosting behavior, this study presents a bioinspired adaptive leg‐claw mechanism that enables UAVs to perform robust and versatile perching and grasping. The design integrates a four‐link tibial structure, tension‐driven deformable feet, and active control, enabling stable perching on various branches and ...

Law Review Publishing: Thoughts on Mass Submissions, Expedited Review, and Potential Reform [PDF]

open access: yes, 2017
The current law review publishing system—in particular, mass submissions and expedited review—works well for prestige-driven professors; however, it places a tremendous burden on the editors of journals lower in the hierarchy. This problem is exacerbated

Light‑Driven Propulsion of Graphene Aerogels in Microgravity

open access: yesAdvanced Science, EarlyView.
Ultralight graphene aerogels convert laser light into thrust. Parabolic‐flight experiments directly compare their motion in microgravity and at 1 g, revealing order‐of‐magnitude enhancements in distance, velocity, and transient thrust when weight and friction are removed (∼50 times enhancement).

Diffusion Characteristics of Ru and Oxygen Vacancies in Ta2O5 for Resistive Random Access Memory Devices: A Density Functional Theory Investigation

open access: yesAdvanced Electronic Materials, EarlyView.
Atomistic analysis of ruthenium (Ru) and oxygen vacancy (OV) diffusion in Ta₂O₅‐based memristors is performed. DFT calculations demonstrate interstitial Ru in Ta₂O₅ has lower diffusion barriers and formation energies than OVs, enhancing mobility and stability.

Conformal Reconfigurable Intelligent Surfaces: A Cylindrical Geometry Perspective

open access: yesAdvanced Electronic Materials, EarlyView.
Cylindrical reconfigurable intelligent surfaces are explored for low‐complexity beam steering using one‐bit meta‐atoms. A multi‐level modeling approach, including optimization‐based synthesis, demonstrates that even minimal hardware can support directive scattering.
