Analytic model for neutral penetration and plasma fueling
Neutral atoms recycled from wall interaction interact with confined plasma, thereby refueling it, most strongly in the region closest to the wall. This occurs near the X-point in diverted configurations, or else near the wall itself in limited configurations. A progression of analytic models are developed for neutral density in the vicinity of a planar or linear source in an ionizing domain. First-principles neutral transport simulations with DEGAS2 are used throughout to test the validity and …

The IRS open sourced much of its incredibly popular Direct File software as the future of the free tax filing program is at risk of being killed by Intuit’s lobbyists and Donald Trump’s megabill.
Meanwhile, several top developers who worked on the software have left the government and joined a project to explore the “future of tax filing” in the private sector

The IRS Tax Filing Software TurboTax Is Trying to Kill Just Got Open Sourced
Direct File has been open sourced, and its creators have left government to continue working on the "future of tax filing."

Emergent anisotropic three-phase order in critically doped superconducting diamond films
Two decades since its discovery, superconducting heavily boron-doped diamond (HBDD) still presents unresolved fundamental questions whose resolution is relevant to the development of this material for quantum technologies. We use electrical magnetotransport measurements of critically-doped homoepitaxial single crystal HBDD films to reveal signatures of intrinsic (electronic) granular superconductivity. By studying the dependence of electrical resistivity on temperature and magnetic field vector…

Ferroelectric switching of quantum anomalous Hall effects in MnBi2Te4 films
The integration of ferroelectric and topological materials offers a promising avenue for advancing the development of quantum material devices. In this work, we explore the strong coupling between topological states and ferroelectricity in the heterostructure formed by interfacing MnBi2Te4 (MBT) thin films and monolayer In2Te3. Our first-principles calculations demonstrate that the polarization direction in In2Te3 can strongly alter electronic band structures in the MBT/In2Te3 heterostructure, …

Integer-Clustering Optimization of Hydrogen and Battery EV Fleets Considering DERs
Electrified transportation leads to a tighter integration between transportation and energy distribution systems. In this work, we develop scalable optimization models to co-design hydrogen and battery electric vehicle (EV) fleets, distributed energy resources, and fast-charging and hydrogen-fueling infrastructure to efficiently meet transportation demands. A novel integer-clustering formulation is used for optimizing fleet-level EV operation while maintaining accurate individual vehicle dispat…

WATCH: Raiders Cornerback Jakorian Bennett Following Minicamp https://www.si.com/nfl/raiders/las-vegas-jakorian-bennett-patrick-graham-pete-carroll

HyperCard was magnificent. Still is.
The HyperTalk language was cool — but even cooler IMO was the way the dev environment mixed code with direct manipulation of the UI. There are lots of problems with that approach for generalized Ui development, yes, but the experience of it was magical.
Unity and the like have a similar editor structure — edit UI objects, attach code to them — but the feeling is totally different somehow.
