Nano-resolved sensing of 3D electromagnetic fields via single emitters' extreme variation of enhanced spontaneous emission
Controlling quantum light-matter interactions at scales smaller than the diffraction limit at the single quantum emitter level is a critical challenge to the goal of advancing quantum technologies. We introduce a novel material platform that enables precise engineering of spontaneous emission changes in molecular single emitters through 3D nanofields. This platform is based on a 3D hollow plasmonic nanomaterial arranged in a square lattice, uniformly scalable to the centimeter scale while maint…

I'm reading Catastrope Ethics by Travis Rieder. This passage drives home why we need to question how politicians talk so promisingly about negative-emissions tech that sucks CO2 from the air:

"The other category of negative-emissions technology avoids at least the land-use problem and is popular among the more techno-optimistic, as it does something that sounds borderline magical: it sucks CO, directly from the air and returns it to the ground. There's only one problem, wh…

A Production-Ready Machine Learning System for Inclusive Employment: Requirements Engineering and Implementation of AI-Driven Disability Job Matching Platform
Employment inclusion of people with disabilities remains critically low in Italy, with only 3.5% employed nationally despite mandatory hiring quotas. Traditional manual matching processes require 30-60 minutes per candidate, creating bottlenecks that limit service capacity. Our goal is to develop and validate a production-ready machine learning system for disability employment matching that integrates social responsibility requirements while maintaining human oversight in decision-making. We em…

The proposed sell-off of federal lands in the Senate budget bill includes a LOT of Joshua tree habitat—the trees grow in some of the largest areas of undeveloped land in the lower 48 states
The place where eastern and western Joshua trees hybridize, north of Creech AFB, is included

Infinite-dimensional symmetries in plane wave spacetimes
We study the asymptotic symmetries of the Nappi-Witten spacetime in four dimensions, a plane wave arising as the Penrose limit of AdS$_2\times S^2$. Imposing suitable boundary conditions at large transverse distance, we uncover a new infinite-dimensional symmetry algebra allowing for non-trivial central extensions. The corresponding phase space encompasses the most general four-dimensional pp-wave metric, including in particular the Penrose limit of Kerr black holes.

Side-Channel Extraction of Dataflow AI Accelerator Hardware Parameters
Dataflow neural network accelerators efficiently process AI tasks on FPGAs, with deployment simplified by ready-to-use frameworks and pre-trained models. However, this convenience makes them vulnerable to malicious actors seeking to reverse engineer valuable Intellectual Property (IP) through Side-Channel Attacks (SCA). This paper proposes a methodology to recover the hardware configuration of dataflow accelerators generated with the FINN framework. Through unsupervised dimensionality reduction…

Climate change action could dramatically limit rising UK heat wave deaths #UnitedKingdom

Climate change action could dramatically limit rising UK heat wave deaths
A new study suggests that, under realistic scenarios of high emissions and socioeconomic development, annual heat-related deaths in the U.K. could rise to about 50 times current rates by the 2070s, but that climate change mitigation and adaptation could significantly limit this rise.

Diplomaten: Erneute Blockade der EU-Sanktionen gegen Russland
In der Europäischen Union sind offenbar erneut neue Sanktionen gegen Russland am Widerstand der Slowakei gescheitert. Das osteuropäische Land blockierte das 18. Russland-Sanktionspaket, sagten vier EU-Diplomaten der Nachrichtenagentur Reuters. Bereits am Dienstag hatte das osteuropäische Land verhindert, dass Russland wegen des Angriffs a…

EU-Sanktionen gegen Russland: Viel Einigkeit, aber keine Einigung
Beim Treffen der EU-Außenminister sollte das 18. Sanktionspaket gegen Russland beschlossen werden. Doch die Slowakei stellt sich quer. Auch die Finanzierung der "Patriot"-Systeme für die Ukraine ist offen.

The Fourier coefficients of the critical holomorphic multiplicative chaos
The holomorphic multiplicative chaos (HMC) is a holomorphic analogue of the Gaussian multiplicative chaos. It arises naturally as the limit in large matrix size of the characteristic polynomial of Haar unitary matrices, and more generally, random matrices following the Circular-$β$-Ensemble. In a previous article, Najnudel, Paquette and Simm prove that in the $L^2$ phase $β> 4$, the appropriately normalized Fourier coefficient of the HMC converges in distribution to the square root of the tot…
