It's time for the #EV industry to hold itself to a higher standard when it comes to roaming. You can't have your cake and eat it. Make the cake bigger!

I fully agree with Christian Weinberger's call here: Isn't it time we stop pretending roaming works and start holding the ecosystem to a higher standard? As a fossil in this industry, I remember how EV roaming took off 15 years ago – it was a no-brainer from a user perspective and a logical step to ensure that the EV charging market could grow, benefiting everyone in the sector. As an early electric car driver eager to travel abroad, I spent a lot of time getting the right passes for local n…

Fresnel reflection coefficients in the Fourier domain for a planar surface in uniform motion parallel to its interface
The optical reflection coefficient of a dielectric medium moving uniformly in the plane spanned by its surface is rigorously calculated using classical electrodynamics and special relativity, and expressed in the Fourier domain, as a function of the incident frequency and wavevector, valid in both the far- and near-field regimes. It is found that cross-polarisation appears as a consequence of the motion, except when it is directed along the plane of incidence. As an example, using a Drude model…

Parity violation in photon quasinormal modes of black holes
Given that black holes are ubiquitous in the universe and axion-like scalar fields are potential candidates for dark energy and/or dark matter, it is natural to consider cosmological black holes endowed with axion hair. We investigate the photon quasinormal modes of a Schwarzschild black hole with axion hair where the electromagnetic field is coupled to the axion field via a Chern-Simons interaction. We derive the master equations for the electromagnetic field as a set of coupled equations for …

Cloud-Based Interoperability in Residential Energy Systems
As distributed energy resources (DERs) such as solar PV, batteries and electric vehicles become increasingly prevalent at the edge, maintaining grid stability requires advanced monitoring and control mechanisms. This paper presents a scalable smart grid gateway architecture that enables interoperability between Modbus-based inverters and IEEE 2030.5 cloud-based control systems. The proposed solution leverages Azure cloud services and edge-computing gateway devices to support dynamic configurati…

AutoAdv: Automated Adversarial Prompting for Multi-Turn Jailbreaking of Large Language Models
Large Language Models (LLMs) continue to exhibit vulnerabilities to jailbreaking attacks: carefully crafted malicious inputs intended to circumvent safety guardrails and elicit harmful responses. As such, we present AutoAdv, a novel framework that automates adversarial prompt generation to systematically evaluate and expose vulnerabilities in LLM safety mechanisms. Our approach leverages a parametric attacker LLM to produce semantically disguised malicious prompts through strategic rewriting te…

Ultrafast electron dynamics upon above band-gap excitation in epitaxial LaFeO$_3$(001) thin films
Strong electron correlations in perovskite oxides give rise to rich and often unexpected electronic phenomena. In this study, we present a comprehensive surface-science investigation of epitaxial thin films of the charge-transfer insulator LaFeO$_3$(001). The characterization includes low-energy electron diffraction (LEED), high-resolution electron energy loss spectroscopy (HREELS), and photoemission spectroscopy. We map both the occupied and unoccupied electronic states using two-photon photoe…

Common superconducting transition in under and overdoped cuprate superconductors
Underdoped cuprate superconductors are believed to be strongly correlated with electronic systems with small phase stiffness leading to a large phase fluctuation region is known as the pseudogap state. With increasing doping it is generally agree that they become Fermi liquid, rendering the end of the superconductivity due to the sufficiently large electronic screening. However, this scenario does not stand against a recent experiment\cite{OverJJ2022} that combined magnetic susceptibility and S…

I don’t agree in one respect:
Neither OOP nor FP (nor 4GLs nor IDEs nor SOAs nor any of the other new hotnesses past) had anything remotely resembling the current money behind them. None led to companies speculatively laying off tens of thousands of employees for imagined productivity boosts that had not actually arrived yet. None shaped whole election cycles, or led to national proposals for preemptive deregulation. None led to the construction of nuclear power plants or the draining of rivers. None sent oligarchs or fascists into spasmodic wet dreams of world domination. None started quasi-religious cults like EA.
All •that• is the part that feels like blockchain — but even worse, if such a thing is possible.

Pressure-induced band gap energy increase in crystalline lactose
Lactose is widely used in agri-food and pharma industries. New materials that can be obtained from renewable sources are currently being sought. I have studied the effect of hydrostatic pressure on structural properties of currently known forms of crystalline lactose within the framework of density functional theory with van der Waals interactions. The computed parameters have good agreement with experimental data. The effect of mechanical deformations on electron structure of crystalline lacto…

Trade-Offs in EuBa2Cu3Oy Films containing Artificial Pinning Centers: Higher Critical Currents yet Faster Vortex Creep
The electromagnetic properties of type-II superconductors depend on vortices-magnetic flux lines whose motion introduces dissipation that can be mitigated by pinning from material defects. The material disorder landscape is tuned by the choice of materials growth technique and incorporation of impurities that serve as vortex pinning centers. For example, metal organic deposition (MOD) and pulsed laser deposition (PLD) produce high-quality superconducting films with uncorrelated versus correlate…
