Optimal Sizing of Community Photovoltaic and Battery Energy Storage Systems with Second-Life Batteries in Peer-to-Peer Energy Communities
This article presents a mixed-integer second-order cone programming model to determine the optimal sizing of a community-shared photovoltaic and battery energy storage system (PV-BESS) within a peer-to-peer (P2P) energy trading framework. The model accounts for heterogeneous users who may already own individual PV or PV-BESS systems and aims to enhance the overall energy autonomy of the energy community. A key feature of the model is the explicit comparison between first-life (FL) and second-li…

Community Covert Communication - Dynamic Mass Covert Communication Through Social Media
Since the early 2010s, social network-based influence technologies have grown almost exponentially. Initiated by the U.S. Army's early OEV system in 2011, a number of companies specializing in this field have emerged. The most (in)famous cases are Bell Pottinger, Cambridge Analytica, Aggregate-IQ and, more recently, Team Jorge. In this paper, we consider the use-case of sock puppet master activities, which consist in creating hundreds or even thousands of avatars, in organizing them into comm…

Why Compressed Metal Hydrides are Near-room-temperature Superconductors
This contribution provides a partial response to the titular statement since, it will be claimed,the ``why'' is not yet understood, but there is a pathway for achieving a more complete understanding. The sense of the community has been that, given a prospective metal hydride and pressure, the energy landscape can be surveyed computationally for thermodynamic and dynamic stability, the Eliashberg spectral function with its required input (energy bands, phonon modes, coupling matrix elements) can…

Energy Experience Design
The material footprint of information and communications technology (ICT) systems is both significant and growing, inspiring a variety of conversations around sustainability and climate justice. In part this effort has been catalysed by past scholarship and analysis from the LIMITS community. This paper examines energy storage systems for computing, particularly batteries -- which are discarded at the rate of 15 billion a year worldwide. The International Energy Agency (IEA) is now referring to…

Breaking Language Barriers: Equitable Performance in Multilingual Language Models
Cutting-edge LLMs have emerged as powerful tools for multilingual communication and understanding. However, LLMs perform worse in Common Sense Reasoning (CSR) tasks when prompted in low-resource languages (LRLs) like Hindi or Swahili compared to high-resource languages (HRLs) like English. Equalizing this inconsistent access to quality LLM outputs is crucial to ensure fairness for speakers of LRLs and across diverse linguistic communities. In this paper, we propose an approach to bridge this ga…

Accelerating Garfield++ with CUDA
Garfield++ is extensively used within the gaseous detector community for comprehensive detector simulations, supporting the full experimental life cycle from design to operation and calibration. The emergence of micro-pattern gaseous detectors has necessitated computationally intensive microscopic avalanche simulations. The acceleration of one of Garfield++'s most demanding algorithms, AvalancheMicroscopic, by porting it to graphics processing units using NVIDIA's CUDA framework is described. T…

Science Matters - Small or big, new nuclear reactors are not climate solutions
Despite the efforts of industry and its supporters to convince us otherwise, coal, gas and oil are outdated, inefficient, polluting energy sources, especially compared to alternatives. Some people, including politicians, are touting nuclear power as a good alternative. Is it?
it’s far from clean, and it’s rife with problems

Exact calculation of photon polarization observables in Bethe-Heitler process
The effects of polarization transfer from the initial electron to the bremsstrahlung photon in the electron-nucleus scattering (Bethe-Heitler process) are considered. The calculation is done without the assumption of smallness of the electron mass. Detailed comparison with a previous well-known works is done. Some issues related with electron mass neglecting are shown and commented. The results are applicable to the modelling of the polarized cross sections at low energies (even at a few electr…

Integration of Silica in G4CMP for Phonon Simulations: Framework and Tools for Material Integration
Superconducting detectors with sub-eV energy resolution have demonstrated success setting limits on Beyond the Standard Model (BSM) physics due to their unique sensitivity to low-energy events. G4CMP, a Geant4-based extension for condensed matter physics, provides a comprehensive toolkit for modeling phonon and charge dynamics in cryogenic materials. This paper introduces a technical formalism to support the superconducting qubit and low-threshold detector community in implementing phonon simul…
