A multimodal dataset of computed spectra for organic molecules with a chemistry-constrained agent interface

24,126 computational IR, Raman, UV–Vis, fluorescence, ¹H/¹³C NMR, and C/N/O/F K-edge XANES records for 2,991 organic molecules, with a chemistry-constrained agent for reproducible workflows.

Edge Computing vs. Cloud Computing: Which is the Future?

As businesses strive to improve efficiency, reduce latency, and leverage the power of data, understanding the strengths and limitations of these two computing paradigms is crucial. Full article: https://davidohnstad.com/edge-computing-vs-cloud-computing-which-is-the-future/

Two Quotients of One Machine

Two Quotients of One Machine Myhill–Nerode cut complexity and locality cohomology of binary addition Driven by Dean A. Kulik September 2026 Abstract An n-bit modular adder is read two ways, and both readings are computed exactly. Theorem A (the reader cut). Present the input positions of (a,b) ↦ a+b mod 2ⁿ in an arbitr...

Physics-Informed Reconstruction of Unmeasurable Cardiac Fields from Real Data: Electrocardiographic Imaging and 4D-Flow Aortic Pressure, Verified Against Known Answers, with Null Results

Two clinically decisive cardiac quantities cannot be measured where they are needed: the heart-surface potential map (measured only with an invasive electrode cage) and the intra-vascular pressure field (measured only with a catheter). Each is tied by a governing equation to a quantity measurable non-invasively, the bo...

Berge-Fulkerson Covers, Cycle Double Covers, Flows and Exact Normality Defects of the First Counterexamples to the Petersen Coloring Conjecture

Jaeger's Petersen coloring conjecture (1988), which asserted that every bridgeless cubic graph admits an edge map onto the Petersen graph sending every vertex star onto a vertex star, was refuted in August 2026: Putman exhibited two nonisomorphic 112-vertex counterexamples with SAT-solver certificates, Jooken gave a hu...

Reproducibility code for inter-county distances along U.S. highway and railway networks

This software package contains the reproducibility code used to construct and validate the dataset of inter-county distances along the real-world highway and railway networks in the contiguous United States. The workflow implements the QGIS–RStudio crosswalk described in the accompanying study, integrating geographic i...

Real-Time Aerodynamic Flow Reconstruction from Ultra-Sparse Sensors via Deep Permutation Networks (DPN) and Idempotent Physical Projections

Real-time estimation of full unsteady aerodynamic flow fields $\mathbf{u}(\mathbf{x}, t) = (u, v)$ from ultra-sparse discrete sensor observations (e.g., $M \le 10$ point velocity probes across thousands of grid cells) is a foundational challenge in active flow control, wind tunnel telemetry, and unmanned aerial vehicle...

fracpll: charge-pump fractional-N PLL design from measured pieces

First release: the charge-pump fractional-N loop, noise, delta-sigma, tuning-curve, lock and measurement-planning machinery distilled from a monolithic GaN-on-SOI HEMT-varactor PLL co-design study, generalized to any technology that fits a charge-pump loop -- CMOS, SiGe, GaN or board-level. The physics-informed-ML and...

A dataset of inter-county distances along the real-world highway and railway networks in the contiguous United States

This dataset provides transportation mode-specific inter-county shortest-path distances along the real-world highway and railway networks in the contiguous United States. The dataset was generated using a QGIS–RStudio crosswalk that integrates geographic information system processing with network-based analysis to tran...

A two-body eigenvalue problem for the resting cortical spectrum: line positions, weights, a dissociation edge, and the speed the screening has to have

A resting cortical spectrum carries a narrow peak near 10 Hz, a weaker and equally narrow peak near 20 Hz, and a broad 1/f background running beneath and above them. Mechanistic accounts locate each rhythm in a relaxation time, so a second band requires a second circuit, the ratio of the two amplitudes is predicted by...
