You Can Approximate Pi by Dropping Needles on the Floor

In this simulation, 66 of the 100 needles crossed a line (you can count ’em). Using this number, we get a value of pi at 3.0303—which is not 3.14—but it's not terrible for just 100 needles. With ...

Why multitasking still fails: Study shows brain can't fully do two tasks at once, even with extensive practice

Even with highly extensive training, the human brain is not really capable of performing two tasks simultaneously. Moreover, even the smallest deviations from trained routines can have a significant ...

MuSPaCSA: Multi-Scale Parallel-Channel Self-Attention Network for Point Cloud Classification and Segmentation

Abstract: Point cloud classification and segmentation are fundamental tasks in 3D computer vision. Recently, deep learning-based methods, particularly 3D Transformers, have demonstrated their ...

Pond-dwelling microalga exposes a parallel track for RNA processing

Biology textbooks explain that cells follow a universal rule when processing gene transcripts to make proteins. Non-coding snippets of RNA are bracketed by a guanine-thymine (GT) nucleotide sequence ...
