On the Costs and Benefits of Learned Indexing for Dynamic High-Dimensional Data: Extended Version
One of the main challenges within the growing research area of learned indexing is the lack of adaptability to dynamically expanding datasets. This paper explores the dynamization of a static learned index for complex data through operations such as node splitting and broadening, enabling efficient adaptation to new data. Furthermore, we evaluate the trade-offs between static and dynamic approaches by introducing an amortized cost model to assess query performance in tandem with the build costs…

Here are the three primary kinds of community-based events we’ll be sponsoring during 31 Days of Action:

Open/community lab meetings over Zoom or live-streamed lab tours/demos

Teach-ins at local community centers, churches, parks, basically anywhere that’s not a college campus

Stand Up For Science tabling and demos that include “Ask a Scientist” booths,
pond water under a microscope,
strawberry DNA extraction,
egg drop competitions, …

SUFS 31 Days of Action Guidebook
🧬 WHAT IS STAND UP FOR SCIENCE? Stand Up for Science (SUFS) is a 501(c)(4) non-profit organization born from the rallies held in cities throughout the United States and around the world on March 7th, 2025. We believe that science is a public good that benefits everyone, and we’re leading...

Transcranial focused ultrasound for identifying the neural substrate of conscious perception https://arxiv.org/abs/2507.08517 Indeed I see long-term potential for phased-array tFUS as a visual prosthesis for the late-blind. The company Nudge is developing a phased-array tFUS helmet.

Transcranial Focused Ultrasound for Identifying the Neural Substrate of Conscious Perception
Identifying what aspects of brain activity are responsible for conscious perception remains one of the most challenging problems in science. While progress has been made through psychophysical studies employing EEG and fMRI, research would greatly benefit from improved methods for stimulating the brain in healthy human subjects. Traditional techniques for neural stimulation through the skull, including electrical or magnetic stimulation, suffer from coarse spatial resolution and have limited ab…
