Facts look different in different contexts...
Nigeria, Libya, Caspian Sea, and other oil patches in impoverished places are effectively without the concept of environmental regulation. They flare whatever wherever they want. In Nigeria the rampant theft of unrefined oil and "fire pit refining" is beyond anything done by regulated refiners in TX.
Not that we want to emulate Nigeria or Azerbaijan or Libya...

A nonstandard finite difference scheme for an SEIQR epidemiological PDE mode
This paper introduces a nonstandard finite difference (NSFD) approach to a reaction-diffusion SEIQR epidemiological model, which captures the spatiotemporal dynamics of infectious disease transmission. Formulated as a system of semilinear parabolic partial differential equations (PDEs), the model extends classical compartmental models by incorporating spatial diffusion to account for population movement and spatial heterogeneity. The proposed NSFD discretization is designed to preserve the cont…

Production, Quality Assurance and Quality Control of the SiPM Tiles for the DarkSide-20k Time Projection Chamber
The DarkSide-20k dark matter direct detection experiment will employ a 21 m^2 silicon photomultiplier (SiPM) array, instrumenting a dual-phase 50 tonnes liquid argon Time Projection Chamber (TPC). SiPMs are arranged into modular photosensors called Tiles, each integrating 24 SiPMs onto a printed circuit board (PCB) that provides signal amplification, power distribution, and a single-ended output for simplified readout. 16 Tiles are further grouped into Photo-Detector Units (PDUs). This paper de…

A facile vector substrate platform via BaTiO3 membrane transfer enables high quality solution processed epitaxial PZT on silicon
The direct integration of high-performance ferroelectric oxides with silicon remains challenging due to lattice mismatch, thermal incompatibility, and the need for high-temperature epitaxial growth. Here, a hybrid integration approach is demonstrated in which crystalline BaTiO3 (BTO) membranes are first transferred onto Pt coated Si substrates and subsequently used as vector substrates (VS) for the growth of epitaxial (001) Pb(Zr0.52Ti0.48)O3 (PZT) thin films via chemical solution deposition (C…

We all perform tasks in our day-to-day work that are considered 'non-promotable' – these are crucial for project success, but they won't get you promoted. This is commonly known as 'glue work', a term coined by Tanya Reilly. At Berlin Buzzwords 2025, Fatima Taj shared her personal experience of narrowly avoiding the trap of being permanently stuck with glue work and explained how to handle similar situations.
