Experimental bounds on linear-friction dissipative collapse models from levitated optomechanics
Collapse models constitute an alternative to quantum mechanics that solve the well-know quantum measurement problem. In this framework, a novel approach to include dissipation in collapse models has been recently proposed, and awaits experimental validation. Our work establishes experimental bounds on the so-constructed linear-friction dissipative Diósi-Penrose (dDP) and Continuous Spontaneous localisation (dCSL) models by exploiting experiments in the field of levitated optomechanics. Our res…

Another great example of (charitably) Kruger-Dunning (or more realistically, towering naivity) among the vljmstoligy community.

The reason GHG emissions still aren't falling far or fast enough to avoid global catastrophe is "lack of political will" and "corporate vested interests". The fact is that governments of even nations with undemocratic and tyrannical regimes are in the hands of the populace in the medium to long term. How long would, say, Putin remain in power if he announced a ten year programme to tax meat to the point it's a rare luxury reserved for the wealthy, to transition from petrol and diesel fuels, a crash programme to dump coal and gas for power generation and heating and roll out renewables, abolishing hidden subsidies for concrete manufactures to ensure the the emission externalities are priced in, virtual bans on civilian aviation and so on? Certainly there'd be an interesting Keynesian multiplier effect from all the expenditure and investment*, but he'd still be dangling from a metaphorical lamppost within a few years.
*actually the debt incurred would cause huge inflation.
The other big problem, still, is lack of public understanding. There's "awareness", but here are still huge misapprehension. Eg., many people still seem to think thst net zero would mean a return to mid-20thC climates; people still don't grasp the consequences of passing major tipping thresholds, or that many climate elements (ice sheet melting, ocean circulations,..) have multi-decadal or multi-century lags before reaching a final equilibrium. And they still have no clue how fragile civilisation is, or what life in 2100 -- or 2050! - will be like.
I remain more optimistic than I was 25y ago when I first started taking an interest, though. 2.5°C still looks plausible to me, if current reductions continue to accelerate, given a few weather megadisasters to chivvy us along.

Heavy Ball Momentum for Non-Strongly Convex Optimization
When considering the minimization of a quadratic or strongly convex function, it is well known that first-order methods involving an inertial term weighted by a constant-in-time parameter are particularly efficient (see Polyak [32], Nesterov [28], and references therein). By setting the inertial parameter according to the condition number of the objective function, these methods guarantee a fast exponential decay of the error. We prove that this type of schemes (which are later called Heavy Bal…

3D Positioning using a New Diffraction Path Model
Enhancing 3D and Z-axis positioning accuracy is crucial for effective rescue in indoor emergencies, ensuring safety for emergency responders and at-risk individuals. Additionally, reducing the dependence of a positioning system on fixed infrastructure is crucial, given its vulnerability to power failures and damage during emergencies. Further challenges from a signal propagation perspective include poor indoor signal coverage, multipath effects and the problem of Non-Line-OfSight (NLOS) measure…

ARGO: An Auto-Tuning Runtime System for Scalable GNN Training on Multi-Core Processor
As Graph Neural Networks (GNNs) become popular, libraries like PyTorch-Geometric (PyG) and Deep Graph Library (DGL) are proposed; these libraries have emerged as the de facto standard for implementing GNNs because they provide graph-oriented APIs and are purposefully designed to manage the inherent sparsity and irregularity in graph structures. However, these libraries show poor scalability on multi-core processors, which under-utilizes the available platform resources and limits the performanc…

The "I'm never going to be prevented from having an abortion that I need" voters need to watch more stories like this one!
The law in Texas says, we'd rather create orphans than allow abortions.
