DNA Hypomethylation Is One of the Epigenetic Mechanisms Involved in Salt‐Stress Priming in Soybean Seedlings

open access: yesPlant, Cell &Environment, Volume 49, Issue 7, Page 3764-3776, July 2026.
ABSTRACT Salt‐stress priming enhances the tolerance of plants against subsequent exposure to a similar stress. Priming‐induced transcriptomic reprogramming is mediated by multiple epigenetic mechanisms, the best known of which is histone modifications. However, not much is known about other epigenetic responses.

Sparse Warcasting

open access: yesScottish Journal of Political Economy, Volume 73, Issue 3, July 2026.
ABSTRACT Forecasting economic activity during institutional collapse requires nowcasts derived exclusively from alternative data sources. Such sources are abundant yet theoretically unanchored and potentially weakly informative. This study examines whether sparse supervised dimension reduction extracts reliable signals in a context rich in data but ...

Nonparametric relative recursive regression

open access: yesDependence Modeling, 2020
In this paper, we propose the problem of estimating a regression function recursively based on the minimization of the Mean Squared Relative Error (MSRE), where outlier data are present and the response variable of the model is positive.

DEVELOPMENT OF FREEZE VALVE FOR USE IN THE MSRE [PDF]

open access: yes, 1962
Three types of frozen-seal valves'' were tested for possible use in the MSRE. The seal was melted by direct resistance heat, by induction heat, and by clamp-on Calrod heat. The frozen seal was made in a preformed restriction section of a standard piece of pipe by a cooling-gas jet stream directed at the restriction.

Parametric Model Order Reduction by Box Clustering With Applications in Mechatronic Systems

open access: yesInternational Journal for Numerical Methods in Engineering, Volume 127, Issue 10, 30 May 2026.
ABSTRACT High temperatures and structural deformations can compromise the functionality and reliability of new components for mechatronic systems. Therefore, high‐fidelity simulations (HFS) are employed during the design process, as they enable a detailed analysis of the thermal and structural behavior of the system.

Simulation analysis of heat transfer and flow characteristics of a U-tube heat exchanger in a molten salt reactor

open access: yesHe jishu
BackgroundThe primary heat exchanger (PHX) used in the 10 MWt Molten Salt Reactor Experiment (MSRE) at Oak Ridge National Laboratory (ORNL), is a U-tube heat exchanger, where the shell side (hot side) contains the fuel salt from the primary loop and the ...
