Metabolic and transcriptomic study of pennycress natural variation identifies targets for oil improvement (open access)

Metabolic and transcriptomic study of pennycress natural variation identifies targets for oil improvement

Article describes how, although pennycress, a winter annual, could be grown as a dedicated bioenergy crop, an increase in its seed oil content is required to improve its economic competitiveness. In this work, the authors combined biomass composition with metabolomic and transcriptomic studies of developing embryos from 22 pennycress natural variants to identify targets for oil improvement.

Multitask deep-learning-based design of chiral plasmonic metamaterials (open access)

Multitask deep-learning-based design of chiral plasmonic metamaterials

This article presents an end-to-end functional bidirectional deep-learning (DL) model for three-dimensional chiral metamaterial design and optimization. This ML model utilizes multitask joint learning features to recognize, generalize, and explore in detail the nontrivial relationship between the metamaterialsā€™ geometry and their chiroptical response, eliminating the need for auxiliary networks or equivalent approaches to stabilize the physically relevant output. This model efficiently realizes both forward and inverse retrieval tasks with great precision, offering a promising tool for iterative computational design tasks in complex physical systems. Other potential applications include photodetectors, polarization-resolved imaging, and circular dichroism (CD) spectroscopy.

Prioritizing riparian corridors for ecosystem restoration in urbanizing watersheds (open access)

Prioritizing riparian corridors for ecosystem restoration in urbanizing watersheds

This article explores restoration, rather than protection, being the basis for developing a watershed level strategy for improving water quality in urbanizing watersheds.This study uses a geographical information system (GIS) approach that utilizes riparian characteristics extracted from 40-meter wide corridors centered on streams and rivers. The model was applied to 90 sub-watersheds in the watershed of an important drinking water reservoir in north central Texas, USA.

Rate coeļ¬ƒcients for the OD reaction were also determined over a range of temperatures (262āˆ’374 K) at 100 Torr (He). The OD rate coeļ¬ƒcients were āˆ¼15% greater than the OH values and showed similar temperature dependent behavior with k2(T) = (7.52 Ā± 0.44) Ɨ 10āˆ’13exp[āˆ’(476 Ā± 20)/T] and k2(296 K) = (1.53 Ā± 0.15) Ɨ 10āˆ’13 cm3 moleculeāˆ’1 sāˆ’1. The rate coeļ¬ƒcients for reaction 1 were also measured using a relative rate technique between 296 and 375 K with k1(296 K) measured to be (1.22 Ā± 0.1) Ɨ 10āˆ’13 cm3 moleculeāˆ’1 sāˆ’1, in agreement with the PLPāˆ’LIF results.

Cluster embedding of ionic systems: Point charges and extended ions (open access)

Cluster embedding of ionic systems: Point charges and extended ions

This article presents a detailed analysis of the orbital energies of a representative cluster model of a high spin metal oxide, FeO, that has been made to determine the importance of different embedding schemes to represent the extended oxide crystal. The embedding of cluster models of oxides with point charges and with extensions of the embedding which take into account the spatial extent of the cations is examined with an emphasis on the consequences of this embedding for the relative ionization and excitation energies that are measured in core-level spectroscopies.
