Radiometric Constraints on the Timing, Tempo, and Effects of Large Igneous Province Emplacement

open access: yesGeophysical Monograph Series, Page 27-82., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Hypervision Proton Surgery: The Future Direction of Proton Therapy

open access: yesiNew Medicine, EarlyView.
ABSTRACT Proton beams provide unique physical advantages characterized by a low entrance dose, negligible exit dose, and a sharp Bragg peak, which enable superior sparing of normal tissues and support safe dose escalation for improved tumor control. However, conventional photon‐based fractionation remains widely used in proton therapy, where prolonged ...

Zoning of the nuclear injury epicenter based on the gamma-to-neutron radiation component ratio

open access: yesМедицина неотложных состояний
Background. Zoning of nuclear damage areas according to the degree of impact on infrastructure and population is one of the key methods in assessing the situation and should enable reliable prediction of sanitary and irreversible losses.

Impact of Irrigation Scheduling on Corn Yield and Water Balance in Sandy Soils of Central Minnesota Using the EPIC Model.

open access: yesIrrigation and Drainage, EarlyView.
ABSTRACT Efficient irrigation scheduling is critical in sandy soils to achieve optimum yield and maximum net benefit with minimum environmental concerns. The Environmental Policy Integrated Climate (EPIC) model was used to study the impacts of autoirrigation of corn on crop yield and soil water balance during 2019–2021 at −300 and −450 kPa for loamy ...

Boosting the Photoluminescence of Au@Cu12 Nanoclusters via Strategic Fluorine‐Atom Ligand‐Shell Engineering

open access: yesJournal of the Chinese Chemical Society, EarlyView.
The photophysical performance of gold‐doped copper‐rich nanoclusters can be tuned by surface functionalization. Subtle ligand modification enhances intermolecular interactions, thereby reducing nonradiative decay and markedly improving photoluminescence. Comparative photographs and quantum yield values (Φ = 55% vs.

A Personal Perspective on Metalloprotein Structure and the Future of Macromolecular X‐Ray Crystallography

open access: yesJournal of the Chinese Chemical Society, EarlyView.
While X‐ray crystallography has been the primary method for determining the structures of metalloproteins, cryoEM has taken over this role, illustrated by [4Fe4S]‐cluster containing proteins deposited in the Protein Data Bank. What will be the role for X‐ray crystallography as cryoEM and machine learning methods dominate the initial structural analysis?
