Catalytic Scalable Synthesis of Polyketides Enabled by Chiral Brønsted Acid‐Catalyzed Asymmetric Allylborations

open access: yesThe Chemical Record, EarlyView.
The scalable synthesis of target molecules is crucial for applications such as biological evaluation in medicinal chemistry and even industrial production. We described recent advances in chiral Brønsted acid–catalyzed asymmetric allylboration, which enables access to previously elusive chiral building blocks, and highlight its application to the ...

TNCOA: Efficient Exploration via Observation‐Action Constraint on Trajectory‐Based Intrinsic Reward

open access: yesCAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT Efficient exploration is critical in handling sparse rewards and partial observability in deep reinforcement learning. However, most existing intrinsic reward methods based on novelty rely on single‐step observations or Euclidean distances.

Denoising framework for X‐ray absorption spectroscopy data

open access: yesJournal of Synchrotron Radiation, EarlyView.
We introduce a high‐performance Python‐based XAS denoising package called XASDenoise, which implements our newly developed stationarity warping method and advanced denoising techniques based on Gaussian process regression and a convolutional autoencoder.X‐ray absorption spectroscopy (XAS) is a powerful tool for probing the structural and electronic ...

Clearing the Air: How Fine Particulate Matter Regulations Reshape Farmland Values in U.S. Corn and Soybean Regions

open access: yesJournal of Agricultural Economics, EarlyView.
ABSTRACT We investigate the impact of air quality regulations targeting fine particulate matter (PM2.5) on farmland values in corn and soybean producing counties in the United States over the period 1997–2022. Using self‐reported farmland value data from the Agricultural Census and county‐level pollution classifications provided by the Environmental ...

The transformer gene controls sexual development in Drosophila suzukii

open access: yesInsect Science, EarlyView.
The transformer gene plays a key role in the genetic pathway for sexual development in Drosophila suzukii Abstract The genetic network of sex determination in the model organism Drosophila melanogaster was investigated in great detail. Such knowledge not only advances our understanding of the evolution and regulation of sexual dimorphism in insects ...

Defiant pride: Origins and consequences of ethnic voting

open access: yesAmerican Journal of Political Science, EarlyView.
Abstract Why do voters often remain loyal to ethnic parties despite receiving little in terms of material welfare? I develop a theory focused on the role of dignity concerns in explaining within‐group variation in ethnic party loyalty. Group members who face discrimination from state agencies dominated by outgroups respond with defiant pride, which ...
