A robust PPG foundation model using multimodal physiological supervision
arXiv:2606.07365v1 Announce Type: new Abstract: Photoplethysmography (PPG), a non-invasive measure of changes in blood volume, is widely used in both wearable devices and clinical settings. Recent PPG foundation models either use open-source ICU datasets with pretraining paradigms that require curated data and thus complicate generalization to field-like data, or use closed-source field-like PPG data.
Men's Way-Too-Early Top 25: Kansas, UNC in after d...
Between the first and second editions of the Way-Too-Early Top 25 -- the night of the national championship game and April 27 -- there was massive player movement. More than 2,700 players entered the transfer portal, more than 90 of the top 100 transfers committed quickly and another 60 players entered the NBA draft. But in the month since, things have quieted -- though they're not fully settled just yet.

Milan Momcilovic's commitment to Kentucky last week essentially closed the 2026 transfer portal cycle. The former Iowa State star was the last remaining uncommitted transfer in ESPN's top 100, and barring a surprise coaching change, the dust has mostly settled for the balance of the offseason. Comparing portal classes is an increasingly difficult task.

An NBA postseason highlighted by breakout performances, Game 7 thrillers and more than a few upsets has reached its last chapter: The Finals between the San Antonio Spurs and New York Knicks. San Antonio is seeking its first championship since 2014 after winning 62 games during the regular season and dethroning the Oklahoma City Thunder in the Western Conference finals. New York, ringless since 1973, won 53 games and the NBA Cup before breezing through the Eastern Conference playoffs with a...

WNBA awards: Which leaders, long shots are worth b...
We are almost a month into this action-packed WNBA season, and this is a good time to take a closer look at the awards races that are already starting to take shape. The futures betting market can be volatile over the course of a season, so there's value in tracking where things stand and what could change moving forward. You might recall how things played out last season, when then-reigning MVP A'ja Wilson had fallen to long-shot status to repeat as MVP with odds of +1000.

Life in the ACC certainly isn't boring. In the past year alone, the conference has produced a long and awkward CFP rankings battle, an irate affiliate member, a thrilling national title game run, the strangest tiebreaker result imaginable, an out-of-nowhere 11-win season, the most disappointing team in the country, an epic pro-to-college face-plant, 18 of the 38 best games of the 2025 season, the No. 1 pick in the NFL draft (indirectly) and the most awkward possible move to nine-game...
WNBA Power Rankings: Welcome to the top 2, Dallas
A year ago on this date, the Dallas Wings were 1-9. They would not get to double-digit victories until the last day of the season, Sept. 11, when they finished 10-34. After trudging through that victory desert, 2026 has been like an oasis.
2026 NBA Finals Game 3: San Antonio Spurs at New York Knicks best bets for the total and two player props
The New York Knicks (2-0) are two wins from their first championship since 1973 as they host the San Antonio Spurs (0-2) for Game 3 of the 2026 NBA Finals Monday. This is a burn-the-boats game for San Antonio since no team has ever come back from a 3-0 deficit to win an NBA playoff series. New York grabbed home-court advantage for the finals by winning the series opener, 105-95.Then, the Spurs gave away Game 2 despite getting a "good whistle" from the refs all night and holding Jalen Brunson...
