XOR‐Logic Phase Coding Programmable Metasurface for Low Power‐Consumption Systems

Advanced Science, EarlyView.
By leveraging XOR logic, the biasing‐network complexity of 2D programmable metasurfaces is reduced from m×n to m+n through efficient row‐column control. This enables versatile functions including beam deflection and beamforming, facilitating applications in wireless communications and beyond.

Regularized-renormalized-resummed loop corrected power spectrum of non-singular bounce with Primordial Black Hole formation

European Physical Journal C: Particles and Fields
We present a complete and consistent exposition of the regularization, renormalization, and resummation procedures in the setup of having a contraction and then non-singular bounce followed by inflation with a sharp transition from slow-roll (SR) to ...

Tibar la corda més del compte. Les notícies científiques s'han generalitzat, però el missatge s'ha trivialitzat [PDF]

, 2008
Mere Anarchy is the name of Woody Allen’s latest book in which the film director cultivates the genre of critical stories —farces perhaps?— about the world around us, as he did years ago in, for example, Without Feathers or in Getting even. One of the 18

GraphNeuralCloth: A Graph‐Neural‐Network‐Based Framework for Non‐Skinning Cloth Simulation

Advanced Intelligent Systems, EarlyView.
This study presents a cloth motion capture system and a point‐cloud‐to‐mesh processing method to support the prediction of real‐world fabric deformation. GraphNeuralCloth, a graph neural‐network (GNN)‐based framework is also proposed to estimate the cloth morphology change in real time.

Historicitat i heterodòxia. La divulgació científica de Louis Figuier (1819-1894) [PDF]

, 2012
The life and works of Louis Figuier (1819-1894) are still poorly known. Considered as a second-class author in the pantheon of the great names of modern science, Figuier's popularization books and articles rarely have raised further examination and can ...

Structural problems without structural solutions? Youth leaders' perceptions of their community

American Journal of Community Psychology, EarlyView.
Abstract As young people explore and reflect on the conditions of their neighborhoods and communities, they can forge a critical consciousness—merging their perspectives and analysis to direct both individual and collective actions. Photovoice is a methodological tool that allows participants to document their perspectives and analysis and discuss with

‘Turkeys Cannot Vote for Christmas’: Why Epistemic Disobedience in an Anti‐Black World Matters

Australian Journal of Social Issues, EarlyView.
ABSTRACT Never in the history of global coloniality has the idea of epistemic disobedience been as important as in the 21st century. This is not only because the struggle for decolonisation has shifted from physical confrontation between the coloniser and the colonised into a battle of ideas but also because the former has deployed the idea of ...

, 2008
The 1830s and 1840s saw the proliferating usage of “the Beyond” (Jenseits) as a choice term for the afterlife in German public discourse. This linguistic innovation coincided with the rise of empiricism in natural science.
