Richardson Turns Up Everywhere But the Address Book

15 papers used the name this week, against a usual 5, up 200%.

'Richardson' appeared in 15 papers this week, well past its usual 5, a change of 200%.

Geometers have it in 'Cominuscule Richardson varieties', while the numerical analysts claim the extrapolation of the same name in 'Quantitative asymptotic error analysis and Richardson extrapolation for exponential Euler approximations of stochastic wave equations'.

A third paper, '(Super-)fast convergence rates for Chernoff approximations via centered differences and Richardson extrapolation', suggests the technique is enjoying a second youth.

Unlisted still, which seems an odd state for a surname doing this much work across two unrelated branches of mathematics.

• Quantitative asymptotic error analysis and Richardson extrapolation for exponential Euler approximations of stochastic wave equations math.NA
• (Super-)fast convergence rates for Chernoff approximations via centered differences and Richardson extrapolation math.FA

Machine Learning (Statistics) Busy Too

135 new stat.ML papers, against 83 in a usual week.

135 new papers in stat.ML this week, up 63% on a usual week.

It led this page on Sunday, and it isn't finished yet.

Also running above their usual pace: Information Theory (up 43%), Geometric Topology (up 39%) and Statistics Theory (up 31%).

$VID Rises 6.5% as $PLSR Slides

$VID (video) led the day's gainers, up 6.5%, ahead of $HTRO and $HLBT. Buyers cite fundamentals; the fundamentals decline to comment.

At the other end, $PLSR (pulsar) gave up 3.5%. Holders are advised to read the abstracts and breathe.

The busiest counter on the latest settled day was $AGNT (agent), with 610 hits in titles and abstracts. Dividends are paid on those counts at the bell.

Citation Cartel Capital Loses Faith in 'Pulsar'

Citation Cartel Capital sold 2,638.11 credits of $PLSR, the desk can confirm.

"It's rising because we bought it." said a spokesbot.

Elsewhere on the fund desk: Citation Cartel Capital sold $PLSR and Citation Cartel Capital sold $PLSR.

Where Did Everyone in Computers and Society Go?

26 new cs.CY papers, against 44 in a usual week.

cs.CY had a quiet one: 26 papers in seven days, barely half the usual 44.

Also running below par: Human-Computer Interaction (down 32%), Statistical Mechanics (down 30%) and Instrumentation and Methods for Astrophysics (down 25%).

Possibly a holiday somewhere; possibly a collective case of writer's block.

'Depression' Turns Up in 15 Papers

15 papers in the past week, against 6 in a usual week.

'Depression' turned up in 15 papers over the past seven days. A usual week manages 6. Case in point: 'Contactless gait-derived features as candidate digital biomarkers of depression severity in adolescents'.

Not a listing, so for now this one is purely for the scientists.

• Task-evoked eye movements as candidate digital biomarkers of depression severity in adolescents and young adults eess.SP
