First Sounds, Second Language: How Word Onsets Spark Language Co‐Activation in 3‐Year‐Old Bilinguals
Developmental Science, Volume 29, Issue 5, September 2026.ABSTRACT Adult and young bilinguals co‐activate their languages to different degrees, even in entirely monolingual tasks. However, many studies use translation pairs with high phonological overlap (e.g., the English‐GERMAN: “milk”‐“MILCH”), making it difficult to discern the origin of the co‐activation.

Galileo: The Added Value for Integrity in Harsh Environments
Sensors, 2016 A global navigation satellite system (GNSS)-based navigation is a challenging task in a signal-degraded environments where GNSS signals are distorted by multipath and attenuated by fading effects: the navigation solution may be inaccurate or unavailable.

The Application of a Snowpack Runoff Decision Support System for Rain‐on‐Snow Events
Water Resources Research, Volume 62, Issue 4, April 2026.Abstract Accurately forecasting hydrologic outcomes of rain‐on‐snow (ROS) events is critical for water management and flood mitigation, not only in the western U.S., but globally. This study further refines a Snowpack Runoff Decision Support System (SR‐DSS) using hourly Natural Resource Conservation Service SNOw TELemetry (SNOTEL) data to identify ...

A Comprehensive Calibration Framework for the Northwest River Forecast Center
JAWRA Journal of the American Water Resources Association, Volume 62, Issue 2, April 2026.ABSTRACT We present a comprehensive framework developed by the Northwest River Forecast Center for calibrating hydrologically diverse basins. The framework includes models for snow, soil moisture, routing, channel loss, and consumptive use. Data inputs include a wide range of open‐access datasets for meteorology, land use, topography, and land cover ...

Shades of empire: Evidence from Swedish and Polish–Lithuanian partitions in the Baltics
The Economic History Review, Volume 79, Issue 1, Page 342-376, February 2026.Abstract In this study, we explore the long‐run effects of Swedish and Polish–Lithuanian imperial legacies in the Baltic region. Using a robust regression discontinuity design, we identify persistent differences in socio‐economic development across the South Livonia–Courland and the South Livonia–Lettgallia borders that emerged as a result of the ...
