Security Policy Consistency

open access: yes, 2000
With the advent of wide security platforms able to express simultaneously all the policies comprising an organization's global security policy, the problem of inconsistencies within security policies become harder and more relevant.

PEDOT‐Based Eutectogel Electrode Arrays for Enhanced High‐Resolution Electrogastrography: Fabrication, Stability, and Wearable Performance

open access: yesAdvanced Functional Materials, EarlyView.
Here, we present a high‐density PEDOT eutectogel electrode array for enhanced body surface gastric mapping. Silver electrodes are blade‐coated onto flexible substrates, followed by electrogelation of PEDOT:PSS and the deposition of a PEDOT:LS eutectogel.

Digital Actuation Control of Soft Robotic Origami With Self‐Folding Liquid Crystal Elastomer Hinges

open access: yesAdvanced Functional Materials, EarlyView.
Self‐folding soft‐rigid hybrid robotic origami is enabled by liquid crystal elastomer actuators with embedded Joule heating and closed‐loop digital control. Digitally addressable hinges provide reversible and programmable transitions between distinct folded states while maintaining actuation performance at high cycle counts (over 1500).

Toxoplasmic encephalitis unmasked during treatment for miliary tuberculosis in a patient with human immunodeficiency virus infection: a case report and literature review

open access: yesTropical Medicine and Health
Background Toxoplasmic encephalitis (TE) and tuberculoma are the leading causes of ring-enhancing brain lesions in patients with human immunodeficiency virus (HIV) infection. Because imaging findings of the two conditions overlap and cerebrospinal fluid (

Global Health Security in an Era of Explosive Pandemic Potential [PDF]

open access: yes, 2017
Pandemics pose a significant risk to security, economic stability, and development. Annualized expected losses from pandemics are estimated at $60 billion per year. Despite the certainty and magnitude of the threat, the global community has significantly

Meta‐Rod Mechanical Metamaterials With Programmable Reconfiguration

open access: yesAdvanced 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.

Techniques for Enhanced Physical-Layer Security

open access: yes, 2010
Information-theoretic security--widely accepted as the strictest notion of security--relies on channel coding techniques that exploit the inherent randomness of propagation channels to strengthen the security of communications systems.
