Intraday Patterns in the Cross-section of Stock Returns

, 2010
Motivated by the literature on investment flows and optimal trading, we examine intraday predictability in the cross-section of stock returns. We find a striking pattern of return continuation at half-hour intervals that are exact multiples of a trading ...

DCENT‐I: A Globally Infilled Extension of the Dynamically Consistent ENsemble of Temperature Dataset

Geoscience Data Journal, Volume 13, Issue 2, April 2026.
DCENT‐I infills data gaps in DCENT, producing spatially coherent temperature fields (top) and a slightly higher GMST warming estimate (bottom). Top: December 1877 temperature anomalies (°C; 1961–1990 December baseline) from DCENT (left) and DCENT‐I (right). Bottom: GMST before (DCENT, blue) and after (DCENT‐I, red) infilling.

Geographical and Seasonal Distribution of Australian Pygmy Right Whales (Caperea marginata) Based on Passive Acoustics

Marine Mammal Science, Volume 42, Issue 2, April 2026.
ABSTRACT The pygmy right whale (Caperea marginata) is one of the least studied mysticete species. To shed light on its geographic and seasonal distribution, we compiled archival acoustic recordings from 26 sites across southern Australia and developed a deep‐learning detector for pygmy right whale “doublet” vocalizations.

Adaptive Algal Cultivation Enabled by a Monthly Biomass Forecasting System

Biotechnology and Bioengineering, Volume 123, Issue 3, Page 724-741, March 2026.
The developed monthly algal forecasting system used to predict biomass production for two algal strains (A and B) at two pond water depths (low and high). The highest predicted production, achieved with strain A at a low pond water depth, is selected as the cultivation strategy to guide the next month's algal growth.

Acta Ophthalmologica, Volume 104, Issue 2, Page 193-200, March 2026.
Abstract Purpose To examine the incidence of pars plana vitrectomy (PPV) for full‐thickness macular hole (FTMH), epiretinal membrane (ERM) and floaters over time and across regions in Denmark. Methods This nationwide registry‐based study included all patients undergoing PPV for FTMH, ERM, or floaters in Denmark from 2010 to 2023.

Extreme‐weather risk and the cross‐section of stock returns

Journal of Risk and Insurance, Volume 93, Issue 1, Page 163-198, March 2026.
Abstract We document an extreme‐weather risk premium in the cross‐section of stock returns. Between 1995 and 2019, stocks of domestic U.S. firms with the most negative sensitivity to aggregate storm losses earned an annual excess‐return spread of more than 6 percentage points relative to those with the most positive sensitivity, a difference not ...

Detectability of Phytoplankton Biomass Extremes Using Simulated Satellite Chlorophyll Observations

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Extreme open‐ocean phytoplankton events can influence marine ecosystems, yet their global occurrence, drivers, and consequences remain poorly understood. Most large‐scale studies rely on satellite chlorophyll, which provides only a surface view, is affected by physiological variability, and is often missing due to clouds and low sunlight. Here,
