NeuroScalar: A Deep Learning Framework for Fast, Accurate, and In-the-Wild Cycle-Level Performance Prediction
The evaluation of new microprocessor designs is constrained by slow, cycle-accurate simulators that rely on unrepresentative benchmark traces. This paper introduces a novel deep learning framework for high-fidelity, ``in-the-wild'' simulation on production hardware. Our core contribution is a DL model trained on microarchitecture-independent features to predict cycle-level performance for hypothetical processor designs. This unique approach allows the model to be deployed on existing silicon to…

For today's #FreeSoftwareAdvent here's a tiny tool we have used in our pipeline: pyRenamer is a simple app to rename/renumber a bunch of files.
Unfortunately it's pretty much an abandoned fork of a Python 2 app that has been abandoned for even longer ago. It still works and for renumbering there's no easier solution at hand. But for file name search & replace …

Triple-Tone Microwave Control for Sensitivity Optimization in Compact Ensemble Nitrogen-Vacancy Magnetometers
Ensembles of nitrogen-vacancy (NV) centers in diamond are a well-established platform for quantum magnetometry under ambient conditions. One challenge arises from the hyperfine structure of the NV, which, for the common $^{14}$N isotope, results in a threefold reduction of contrast and thus sensitivity. By addressing each of the NV hyperfine transitions individually, triple-tone microwave (MW) control can mitigate this sensitivity loss. Here, we experimentally and theoretically investigate the …

Abstract: Microwave (MW) field sensing is foundational to modern technology, yet its evolution, reliant on classical antennas, is constrained by fundamental physical limits on field, temporal, and spatial resolutions. Here, we demonstrate an MW electrometry that simultaneously surpasses these constraints by using individual Rydberg atoms in an optical tweezer array as coherent sensors. This approach achieves a field sensitivity within 13% of the standard quantum limit, a response time that exceeds the Chu limit by more than 11 orders of magnitude, and in-situ near-field mapping with {\lambda}/3000 spatial resolution. This work establishes Rydberg-atom arrays as a powerful platform that unites quantum-limited sensitivity, nanosecond-scale response time, and sub-micrometer resolution, opening new avenues in quantum metrology and precision electromagnetic field imaging.

Predicting MacroB12: Data-Driven Assessment of Pre-PEG B12 Utility and Clinical Caveats
MacroB12 interference presents a significant challenge in the diagnosis of Vitamin B12 status, potentially masking true deficiency. To establish robust predictors and quantify the utility of pre-polyethylene glycol (PEG) B12 levels, we conducted a retrospective analysis of 875 individuals with hypercobalaminaemia (greater than 1000 pg/mL), using multiple imputation to handle missing data. Multivariable regression modelling revealed that MacroB12 positivity (less than 30% PEG recovery) was indep…

Generalized Distributions of Host Dispersion Measures in the Fast Radio Burst Cosmology
As is well known, Hubble tension is one of the most serious challenges in cosmology to date. So, it is of interest to measure the Hubble constant by using some new probes independent of cosmic microwave background (CMB) and type Ia supernovae (SNIa). One of the promising probes is the fast radio bursts (FRBs), which could be useful in cosmology. In the literature, the methodology proposed by Macquart {\it et al.} has been widely used, in which both $\rm DM_{IGM}$ and $\rm DM_{host}$ are describ…

Good Morning #Canada
I finished my breakfast this morning only to discover that it's National Maple Syrup Day. A missed opportunity but at least I can share some important facts about Canada's sweet and sticky sauce.
- Indigenous People taught early Canadians how to harvest maple sap and boil it down into a sugary liquid.
- A maple tree can yield sap for up to 100 years, but the trees must be roughly 45 years old before it’s first tapped for syrup making.
- It takes roughly 40 gallons (150 litres) of tree sap to produce 1 gallon (3.8 litres) of syrup.
- Quebec produces 72% of the world’s maple syrup. In 2021, that equaled 133M lbs from Quebec.
- The big bottle of Costco Maple Syrup is from Quebec.
- Maple Syrup only has 1 ingredient. Sap.
- Maple Syrup has an indefinite shelf life but should be frozen if storing for more than 2 years.
And regarding the great Maple Syrup heist, this is still the best report on that famous crime.
