Nucleoporins NPP-10, NPP-13 and NPP-20 are required for HCP-4 nuclear import to establish correct centromere assembly

Journal of Cell Science, 2017
ABSTRACT Centromeres form a chromosomal platform for the assembly of the kinetochores, which are required for orderly chromosome segregation. Assembly of both centromeres and kinetochores proceeds by a step-by-step mechanism that is regulated in time and space.

Groundwater Rise Sustains the World's Largest Alpine Water System Under Global Warming

Advanced Science, EarlyView.
Shallow groundwater depth (SGWD) across the non‐permafrost plains of the Qinghai–Xizang Plateau decreased at averagely 0.02 m year−1, adding 31.44 Gt of freshwater storage from 2000 to 2020 and sustaining ∼53 500 km2 of alpine ecosystems. A vadose‐zone capacity of 426.6 Gt reveals these aquifers as promising reservoirs, highlighting groundwater's ...

Spatio-Temporal Variation in AOD and Correlation Analysis with PAR and NPP in China from 2001 to 2017

Remote Sensing, 2020
Atmospheric aerosols can elicit variations in how much solar radiation reaches the ground surface due to scattering and absorption, which may affect plant photosynthesis and carbon uptake in terrestrial ecosystems.

Evolutionäre, funktionelle und mechanistische Charakterisierung mikrobieller Terpensynthase‐ähnlicher Gene aus Springschwänzen

Angewandte Chemie, EarlyView.
Eine Genomanalyse zeigte das Vorkommen zahlreicher Terpensynthasen des bakteriellen Typs in Springschwänzen. Vier Enzyme aus Sinella curviseta wurden funktionell charakterisiert, was zur Isolierung mehrerer Verbindungen führte, darunter Sinellenether, der erste identifizierte Diterpenether einer Terpensynthase mit einem neuartigen Grundgerüst.

Evolutionary, Functional and Mechanistic Characterisation of Microbial Terpene Synthase‐Like Genes From Springtails

Angewandte Chemie International Edition, EarlyView.
A genome analysis revealed the presence of many bacterial‐type terpene synthases in springtails. Four enzymes from Sinella curviseta were functionally characterised, resulting in the isolation of several compounds including sinellene ether, the first diterpene ether identified from a terpene synthase that represents a novel skeleton.

Reweighting Scheme for the Calculation of Grand‐Canonical Expectation Values in Quantum Monte Carlo Simulations With a Fermion Sign Problem

Contributions to Plasma Physics, EarlyView.
ABSTRACT Ab initio path integral Monte Carlo (PIMC) simulations constitute the gold standard for the estimation of a broad range of equilibrium properties of a host of interacting quantum many‐body systems spanning a broad range of conditions from ultracold atoms to warm dense quantum plasmas.

Linking species distribution models with population abundance to support adaptive fisheries management

Ecography, EarlyView.
Understanding how environmental variability structures essential fish habitat (EFH) is central to managing keystone populations in dynamic marine ecosystems. Using nearly three decades of standardized survey data (1994–2021) from the Adriatic Sea, we present the first basin‐scale, process‐based framework linking estimated habitat suitability and ...
