Excel’s AGGREGATE Fails on Arrays but Works with Grid Ranges

Learn why the Excel AGGREGATE function fails with arrays and how to fix value errors using helper columns or dynamic LAMBDA and BYROW formulas.

AI analysis of data from multiple sensors can improve earthquake detection

One seismometer is often not enough to reliably detect earthquakes or human activity such as underground nuclear tests.

Nautilus array to track missing exoplanet atmospheres

Exoplanet atmospheres have become prime targets for astrobiologists in the search for life beyond Earth. This is because exoplanet surfaces can't be directly imaged yet, so astronomers must get ...

Characterizing Spatial Variability of Soil Organic Carbon Through Improved Machine-Learning Modeling With In Situ Data Resampling: A Case Study in Alaska

Abstract: Sparse and unevenly distributed soil samples across the northern high-latitude region greatly limit the accuracy of soil organic carbon (SOC) mapping. Substantial discrepancies, therefore, ...
