Experimental and Numerical Modal Analysis of Composite Sandwich Structures Using Surfboards as Model Systems

open access: yesAdvanced Engineering Materials, EarlyView.
This article presents an experimental and numerical modal investigation of composite sandwich structures using surfboards as model systems. By comparing different core materials and reinforcement strategies, the study demonstrates how local stiffeners influence vibrational response and introduce characteristic modal features, highlighting modal ...

Becoming global (un)civil society : counter-hegemonic struggle and the indymedia network

open access: yes, 2011
In this article we ask how ‘civil society’ actors and organizations can become constructed and treated as ‘uncivil society’. We contest the notion that ‘uncivil’ necessarily equates with the dark qualities of violence and organized criminality.

Continuous Stiffness Graded Metal–Ceramic Femoral Stems: UMAT‐Based Design and Finite Element Assessment

open access: yesAdvanced Engineering Materials, EarlyView.
Functionally graded metal–ceramic femoral stems are engineered through continuous UMAT‐based stiffness tailoring, eliminating discrete material interfaces while enhancing biomechanical compatibility. Low‐index power‐law gradation optimizes load transfer, reduces stress shielding, and controls implant–bone micromotion, highlighting a materials‐design ...

Reduced Graphene Oxide Transparent Electrodes Enabling Compact Soft Tunable Lenses

open access: yesAdvanced Functional Materials, EarlyView.
By spray‐coating an elastomeric membrane with reduced graphene oxide (rGO) at various surface densities, elastomeric actuators are manufactured. Electro‐mechano‐optical characterizations show the suitability of rGO as an effective material for compliant, semi‐transparent electrodes, enabling soft electrically tunable lenses with a compact form factor ...

Is It Real Type‐II or S‐Scheme? A Three‐Phase Diagnostic Protocol for Identifying Potentially Mislabeled Heterojunction Photocatalysts

open access: yesAdvanced Functional Materials, EarlyView.
Diagnostic analysis via the heterojunction validation funnel. The funnel illustrates the hierarchical stratification of 30 reported Type‐II systems based on the three‐phase, seven‐step diagnostic framework. Complete validation through all phases is achieved by only 3.3% of systems, while 96.7% lack full mechanistic validation, revealing a pervasive ...

Freedom, Firearms, and Civil Resistance [PDF]

open access: yesThe Journal of Ethics, 2021
AbstractThe claim that guns can safeguard freedom is common in US political discourse. In light of a broadly republican understanding of freedom, I evaluate this claim and its implications. The idea is usually that firearms would enable citizens to engage in revolutionary violence against a tyrannical government.
