High-precision radiocarbon measurements of contemporaneous tree-ring wood from the British Isles and New Zealand: AD 1850-950. [PDF]

, 2002
The University of Waikato, Hamilton, New Zealand and The Queen's University of Belfast, Northern Ireland radiocarbon dating laboratories have undertaken a series of high-precision measurements on decadal samples of dendrochronologically dated oak ...

Towards a Compositional Framework for Describing Human Phenotypes

Advanced Science, EarlyView.
The Phenotype Assembly Method (PhenoAM) decomposes phenotype variables into measurable Features and typed Qualifiers, enabling standardized, machine‐readable Phenome Data Elements (PhenoDEs) that preserve measurement context. Applied in the International Human Phenome Project (IHPP), the framework yields 58 371 PhenoDEs and supports component‐level ...

Interannual Modulation of Northern Hemisphere Winter Storm Tracks by the QBO

Geophysical Research Letters, 2018
Storm tracks, defined as the preferred regions of extratropical synoptic‐scale disturbances, have remarkable impacts on global weather and climate systems.

Metastability of Northern Hemisphere Teleconnection Modes

Journal of the Atmospheric Sciences, 2015
Abstract This study applies a finite-element, bounded-variation, vector autoregressive method to assess midtropospheric flow regimes characterized by regime switches between metastable states. The flow is assessed in reanalysis data from three different reanalysis sets assimilating surface data only; surface and upper-air data; and ocean,

Palaeoproteomic Deconvolution of Physical and Genetic Collagen Mixtures

Advanced Science, EarlyView.
ClassiCOL_v2 uses a novel “peptide patching” framework that treats any collagen sample as a patchwork of peptide sequences derived from phylogenetically related species. This allows the algorithm to simultaneously resolve two previously intractable problems: multi‐species samples and/or database deficiencies.

ESTIMATION OF THE ASYMMETRIC VERTICAL VARIATION OF THE SOUTHERN AND NORTHERN HEMISPHERES OF THE EARTH

Геодинамика и тектонофизика, 2015
In previous studies, the northern hemisphere of the Earth is considered to be in compression while the southern one is in expansion. In this study, based on three different methods, we calculate average vertical variations of the two hemispheres from ...

An Arbovirus Cline across the Northern Hemisphere

Virology, 1995
The mode and tempo of arbovirus evolution and dispersal can help to explain the dynamics of pandemics, viral outbreaks, and emerging viruses. By comparing nucleotide and deduced amino acid sequences of their envelope proteins, we describe the continuous distribution of the tick-borne encephalitis (TBE) complex viruses, the most important flaviviruses ...

Astrocytes Coordinate Neurovascular Coupling During Prolonged Sensory Demand via AQP4/TRPA1/BEST1/D‐Serine Signaling

Advanced Science, EarlyView.
Neuronal activation leads to astrocytic transient volume changes, activating transient receptor potential ankyrin 1 (TRPA1) channels, leading to Ca2+ influx. Activation of TRPA1 causes the release of D‐serine through BEST1. Finally, the augmented extracellular levels of D‐serine boost neuronal activity by binding GluN1‐containing NMDARs, leading to CBV

Effect of interplanetary magnetic field Bx on the polar electrojets as observed by CHAMP and Swarm satellites

Earth and Planetary Physics
Based on 16 years of magnetic field observations from CHAMP and Swarm satellites, this study investigates the influence of the Interplanetary Magnetic Field (IMF) Bx component on the location and peak current density of the polar electrojets (PEJs).

Drivers of hemispheric differences in return dates of mid-latitude stratospheric ozone to historical levels [PDF]

Atmospheric Chemistry and Physics, 2013
Chemistry-climate models (CCMs) project an earlier return of northern mid-latitude total column ozone to 1980 values compared to the southern mid-latitudes.
