Angular Momentum Balance of Superrotation in Venus's Middle and Upper Atmosphere Simulated by AFES‐Venus

Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract Based on simulations of the Venusian atmosphere using the AFES‐Venus GCM, we investigated the angular momentum (AM) balance that maintains the atmospheric superrotation (SR) at 35–90 km altitudes. In and above the cloud layer, the Eulerian‐mean meridional circulation consists of Hadley‐like cells at low latitudes and Ferrel‐like cells at ...

Hyper-local geographically weighted regression: extending GWR through local model selection and local bandwidth optimization

Journal of Spatial Information Science, 2018
Geographically weighted regression (GWR) is an inherently exploratory technique for examining process non-stationarity in data relationships. This paper develops and applies a hyper-local GWR which extends such investigations further. The hyper-local GWR

Spatial and Temporal Variability of Eastern Pacific Radiocarbon and Carbon Chemistry From the Ice Age to Today

Paleoceanography and Paleoclimatology, Volume 41, Issue 5, May 2026.
Abstract Proxy records of seawater radiocarbon (14C/C) provide strong constraints on how changes in ocean ventilation contributed to the increase in atmospheric CO2 during the termination of the last ice age (≈18,000‐to‐12,000 years ago). One outstanding problem, however, is the existence of anomalously low deglacial benthic foraminiferal 14C/C in the ...

The Development of a Two-Step Merging and Downscaling Method for Satellite Precipitation Products

Remote Sensing, 2020
Low accuracy and coarse spatial resolution are the two main drawbacks of satellite precipitation products. Therefore, calibration and downscaling are necessary before these products are applied.

Land Value Analysis Using Space Syntax and GWR

Journal of the Korean Association of Geographic Information Studies, 2012
Existing studies on land values tend to show the use of simple euclidean distances as the accessibility variable and OLS as the analysis method. However, applying such euclidean distance-based accessibility to dense CBD areas has limitations in the incorporating the characteristics of network structure whereas using OLS, the typical method for non ...

Early Prediction of Neurological Outcome After Cardiac Arrest‐Rationale and Design of the Prospective International Observational EARLY‐NEURO, a STEPCARE Substudy

Acta Anaesthesiologica Scandinavica, Volume 70, Issue 5, May 2026.
ABSTRACT Background Guidelines discourage prediction of neurological outcome in comatose patients within the first 72 h after cardiac arrest. Increasing evidence suggests that patients with the most severe brain injury and those with no or minimal brain injury may be identified before 72 h using novel methods.
