Monoclonal Antibodies; Detection Tools for Wheat Alpha‐Amylase Proteins

Cereal Chemistry, EarlyView.
ABSTRACT Background and Objectives Expression of alpha‐amylase proteins during germination or other physiological events may lower grain soundness and have a negative impact on end‐use quality. The objective of the current study was to validate two new monoclonal peptide antibodies for wheat alpha‐amylases and describe alpha‐amylase expression in ...

Coupling Atomic Confinement With CO2 Pressure for Selective and Stable CO2 Electroreduction

Carbon Energy, EarlyView.
The coupling of high‐pressure operation with atomic‐scale catalyst design was investigated via an electrochemical cation implantation (ECI) process to create confined reaction environments over SnOx catalyst. The synergistic interplay between structural confinement and CO2 pressure was investigated, and the reaction mechanism for CO2RR to CO was ...

Development of a semi-persistent floating terminus at San Quintín Glacier (Northern Patagonia Icefield), the last piedmont glacier in the Andes

Annals of Glaciology
The piedmont lobe of San Quintín Glacier, the largest outlet of the Northern Patagonia Icefield, has recently entered a phase of rapid frontal retreat. We present results from a helicopter-borne ground-penetrating radar (GPR) survey conducted in May 2019

Boron Monofluoride Complexes Bearing π‐Expanded Coumarin Subunits: Facile Synthesis, Crystal Structure, and Solid‐State Enhanced Emission

Chemistry – A European Journal, EarlyView.
We here report the design, facile synthesis, experimental, and theoretical characterization of a novel class of monofluoroborate compounds featuring π‐expanded coumarin subunits displaying solid‐state enhanced Emission. The origin of this phenomenon is disclosed by combined theoretical and spectroscopic investigations.

The life and work of Ernest Sydney Keeping

Canadian Journal of Statistics, EarlyView.
Abstract This article reviews the life and contributions of Ernest S. Keeping (1895–1984), a British‐born physicist who became a mathematics professor at the University of Alberta in 1929. He played a pivotal role in shaping the university's Mathematics Department, serving as its head from 1954 to 1961, and continuing to teach until 1970, nine years ...

Estimation and Analysis of Glacier Mass Balance in the Southeastern Tibetan Plateau Using TanDEM-X Bi-Static InSAR during 2000–2014

Atmosphere
In recent decades, glaciers in the southeastern Tibetan Plateau (SETP) have been rapidly melting and showing a large scale of glacier mass loss. Due to the lack of large-scale, high-resolution, and high-precision observations, knowledge on the spatial ...

Spatio‐temporal dynamics of ringed seal density and habitat use in the Arctic's Last Ice Area

Ecography, EarlyView.
The Arctic is warming at approximately four times the global rate, driving widespread decline in sea ice extent, thickness, and seasonal duration. The ecological consequences of these rapid changes remain poorly understood within the Last Ice Area, a region that includes northern Ellesmere Island and the northwest of Greenland, projected to retain ...

Spatial variation and predictors of plant species' intrinsic climate sensitivity across the conterminous United States

Ecography, EarlyView.
Understanding how species' sensitivity to climate varies spatially across their ranges and elucidating the important causes is essential for identifying ecologically meaningful geographic units and conservation actions for biodiversity. In this study, we estimated climatic occurrence niches of vascular plants to explore the spatial variation in species'

Securing Water in a Changing Climate: A Transient Solar Desalination Model for the Sundarbans, Bangladesh

Energy Science &Engineering, EarlyView.
This graphical abstract presents a solar‐powered reverse osmosis (RO) system for the Sundarbans, Bangladesh. Mechanistic modeling reveals a critical seasonal mismatch: during the monsoon, feed water salinity peaks (24.8 ppt) while solar irradiance drops significantly.
