Abstract: In the primate visual system, center-preferring cortical populations have higher spatial resolution and overlap face- and word-selective regions while periphery-preferring populations have lower spatial resolution and overlap scene-selective regions. This "eccentricity bias" may reflect differential task-relevance: central vision may better support fine-grained tasks like face recognition and reading, while peripheral vision may better support scene understanding. To test whether eccentricity-dependent coding can emerge from natural experience, we used egocentric video and eye-tracking data from the Visual Experience Dataset (VEDB). We trained ResNet-18 models using contrastive learning (SimCLR) on frames modified to isolate different eccentricities (gaze-contingent fovea-only crops, periphery-only crops, and periphery-only crops with a NeuroFovea transform applied). We evaluated downstream task performance and model alignment with human fMRI data (Natural Scenes Dataset; encoding models). In-domain VEDB frame classification showed systematic differences between fovea- and periphery-only models across categories, indicating differential informativeness across tasks. On downstream classification, VEDB-pretrained models generalized better to scene categorization (Places365) than face recognition (VGGFace2), with fovea-only models stronger on both. Across visual cortex, VEDB-pretrained models matched neural predictivity of models trained on mid-sized non-egocentric datasets (ImageNet-100), suggesting egocentric data supports emergence of cortically-aligned representations. In scene-selective cortex (PPA, RSC), periphery-only models held a small but consistent advantage in explained variance over fovea-only models, suggesting these regions are aligned with peripheral statistics. Together, these results suggest egocentric experience may adaptively constrain cortical information processing.

How mature is this repository? My long quest for open-source software metrics
When I discover an open-source software project for the first time, how can I estimate whether it is mature, healthy and usable?
I just released OSSTRL - Open Source Software Technology Readiness Level to help me calculating the maturity of open-source projects.

We’re not yet sure whether TOI-2155b is quite a star.
But it seems to live on the fascinating boundary between a celestial beacon blazing through the heavens and a failed star that never quite ignites sustained hydrogen fusion.
If an object isn’t quite big enough to generate much pressure
– or if fusion doesn’t really kick off properly for some other reason
– the gas becomes a kind of “failed star” known as a brown dwarf.
These objects are hot early in life,

The Trump DOJ has no right to seize Michigan's voter data,
the 6th Circuit's majority rules,
in alignment with every district court to have considered the question.

The Radio Image Framing Protocol (RIFP) 1.0 is an experimental, extensible standard for sending images over low-rate radio links.
The default rifp-cpfsk-4800 profile uses binary continuous-phase FSK and can be deployed around 433.92 MHz where local regulation permits it. RIFP itself is not tied to 433 MHz or to FSK and can be used in any frequency bands.
I'm still exploring various low-cost options for a device that can receive and display images on an e-ink screen in emergency areas or similar environments.
