An Inversion Formula for Multivariate Power Series [PDF]

arXiv, 2012
For formal multivariate power series $\varphi(x)$ an inversion formula of the form $$ \varphi^{-1}(x)=x +\sum_{m=1}^{\infty}\sum_{k=0}^m (-1)^k(m k)\varphi^{\circ k}(x) is offered$$.

Wood Anatomical and Hydraulic Traits of Tamarix Species Across a Large Eurasian Gradient Show a Stronger Climatic Than Phylogenetic Signal

Journal of Biogeography, Volume 52, Issue 5, May 2025.
ABSTRACT Aim Tamarisk (Tamarix) is the predominant but taxonomically complex genus of the Tamaricaceae. The morphologically similar shrub or tree species grow in arid, salt‐influenced habitats of Eurasia and Africa. We sampled woody shoots of seven species at the eastern margin (NW China; T. ramosissima) and the centre (Uzbekistan; T.

Intraseasonal Linkages of Winter Surface Air Temperature Between Eurasia and North America

Geophysical Research Letters, Volume 52, Issue 7, 16 April 2025.
Abstract Wintertime temperature extremes sometimes show a continental linkage between Eurasia and North America (NA), but whether these connections are coincidental or dynamically robust remains unclear. This study investigates the linkages of the leading intraseasonal temperature patterns between Eurasia and NA, focusing on the underlying dynamic ...

Severe Extreme Cold Event in Beijing‐Tianjin‐Hebei Region Tied to Mid‐High‐Latitude Intraseasonal Waves

Geophysical Research Letters, Volume 52, Issue 7, 16 April 2025.
Abstract Extreme cold events (ECEs) have intensified in East Asia over the past decades, disrupting socio‐economic activities and public health. Understanding the mechanism and accurate prediction are crucial yet challenging. This study explores the causes and prediction biases for a severe ECE in Beijing‐Tianjin‐Hebei (BTH) during the 2022 Winter ...

Variability of Autumn Tropical Pacific Yellowfin Tuna Tied to the Spring North Atlantic Tripole

Geophysical Research Letters, Volume 52, Issue 7, 16 April 2025.
Abstract Climate change affects the spatial distribution and abundance of yellowfin tuna (Thunnus albacares, YFT) in the tropical Pacific, yet the mechanisms linking remote climate modes to YFT dynamics remain unclear. This study finds that the variability of autumn tropical Pacific YFT is tied to the spring sea surface temperature anomalies (SSTAs) of

EFFECTIVENESS OF WINTER WHEAT VARIETIES OF WORLD SELECTION IN SOUTH URAL

Russian Journal of Agricultural and Socio-Economic Sciences, 2013
Varieties of winter wheat of world selection were studied in the conditions of South Ural. The conducted researches showed that in conditions of a steppe zone of South Ural possibly receiving more than 5,0 t of grain of winter wheat. For a steppe zone of South Ural four effective grades of winter wheat are defined: Kolos 47, Nika, KNIISH 756 ...

A LEAP Forward in Wildlife Conservation: A Standardized Framework to Determine Mortality Causes in Large GPS‐Tagged Birds

Ecology and Evolution, Volume 15, Issue 4, April 2025.
A novel framework for determining the causes of mortality of large GPS‐tagged birds, the LIFE EUROKITE Assessment Protocol (LEAP), was developed. LEAP integrates GPS tracking data, site investigation, and necropsy to derive mortality causes and a corresponding certainty score. Two case studies demonstrated improvements in mortality assessments compared
