Floating-Point Hell: Why Your R Multivariate Normal Sampling Isn't Reproducible

Floating-Point Hell: Why Your R Multivariate Normal Sampling Isn't Reproducible

This post details the author's debugging journey helping colleagues resolve a reproducibility issue in their R code involving multivariate normal distribution sampling. The problem stemmed not from bugs in R or the MASS package, but from the inherent quirks of floating-point arithmetic. Despite using `set.seed()` to control the random number generator (RNG), the same code produced different results on different machines due to floating-point rounding errors in `MASS::mvrnorm()`. A deep dive revealed that `MASS::mvrnorm()`, using eigendecomposition, is highly sensitive to tiny input perturbations, potentially flipping eigenvector signs and breaking reproducibility. `mvtnorm::rmvnorm()`, employing Cholesky decomposition, proves more robust. The author recommends using `mvtnorm::rmvnorm()` with `method = "chol"` for improved reproducibility.

Go Iterators: A Tale of Purity and Impurity

2025-05-31

Go 1.23 standardized iterators, powerful functions that can be closures. However, the official documentation's classification of iterators is ambiguous. The author proposes a clearer distinction between 'pure' and 'impure' iterators: 'pure' iterators restart each time, while 'impure' iterators may retain state. The article explores various iterator types and the trade-offs between performance and consistency, concluding that Go's iterator landscape is still evolving, with conventions and terminology needing further refinement.

Millions of CT Scans Linked to Increased Cancer Risk

A new study from UC San Francisco reveals that CT scans may be responsible for up to 5% of all annual cancers. The study, published in JAMA Internal Medicine, estimates that the 93 million CT scans performed in 2023 in the US could lead to nearly 103,000 cancer cases—three to four times higher than previous estimates. Infants and children face the greatest risk, but adults are also vulnerable due to higher scan frequency. Researchers urge a reduction in both the number and dosage of CT scans to mitigate this significant health concern. While CT scans are invaluable for diagnosis, the ionizing radiation they emit is a known carcinogen. The study highlights the need for better informed consent and reduced overuse of CT scans.

Locating RFI Sources Using Near-Field Corrections: A Study for 21cm Cosmology During the Epoch of Reionization

2025-02-27

Researchers have developed a novel method to locate radio frequency interference (RFI) sources, particularly those from near-field objects like airplanes, using near-field corrections. This method combines far-field phasing, near-field corrections, and beamforming to precisely pinpoint the 3D location of RFI emitters by maximizing the coherence of curved near-field signals. This is more efficient than traditional flagging, preserving more usable data and enhancing the chances of detecting the 21cm signal during the Epoch of Reionization. Results demonstrate effective altitude estimation of RFI emitters, revealing performance differences under varying observational conditions, laying the groundwork for more precise RFI removal in the future.

LHC Ultraperipheral Collisions Unravel the Mystery of Gluon Saturation

Ultraperipheral collisions (UPCs) at the Large Hadron Collider (LHC) offer a unique window into gluon dynamics. Experiments use photons to probe gluons within protons and nuclei, investigating gluon saturation—a dynamic equilibrium between gluon splitting and recombination. Researchers found that as energy decreases, the number of gluons in hadrons increases, forming 'gluonic hotspots' that overlap in the gluon saturation regime. The experiments also observed nuclear shadowing, where nuclei contain fewer gluons than expected. These findings shed light on the origin of 99% of the visible universe's mass and the nature of the strong interaction. Future LHC runs and the Electron-Ion Collider (EIC) will further explore gluon dynamics, uncovering more mysteries.
