High-Resolution X-Ray Computed Tomography: A New Workflow for the Analysis of Xylogenesis and Intra-Seasonal Wood Biomass Production

open access: yesFrontiers in Plant Science, 2021
Understanding tree growth and carbon sequestration are of crucial interest to forecast the feedback of forests to climate change. To have a global understanding of the wood formation, it is necessary to develop new methodologies for xylogenesis ...

Development process and trend of medium and low yield field reconstruction in Shaanxi Province [PDF]

open access: yesE3S Web of Conferences, 2023
The transformation of medium and low yield grain fields is an important part of cultivated land regulation, which is basically consistent with the requirements of high standard farmland construction. The cultivated land consolidation has experienced from

Pathway engineering for high-yield production of lutein in Escherichia coli [PDF]

open access: yesSynthetic Biology, 2021
Abstract Lutein is an industrially important carotenoid pigment, which is essential for photoprotection and photosynthesis in plants. Lutein is crucial for maintaining human health due to its protective ability from ocular diseases. However, its pathway engineering research has scarcely been performed for microbial production using ...

A series of equivalent area circle yield criteria based on unified strength theory [PDF]

open access: yesE3S Web of Conferences, 2021
Unified strength theory considering the influence of the intermediate principal stress is widely used in geotechnical engineering, but the singularities bring inconvenience to the numerical calculation.

Low-Frequency Noise Behavior of AlGaN/GaN HEMTs with Different Al Compositions

open access: yesCrystals, 2020
AlxGa1−xN/GaN heterostructures with two kinds of Al composition were grown by metal organic chemical vapor deposition (MOCVD) on sapphire substrates. The Al compositions in the AlGaN barrier layer were confirmed to be 13% and 28% using high resolution X ...

Thermodynamics of one and two-qubit nonequilibrium heat engines running between squeezed thermal reservoirs [PDF]

open access: yes, 2022
Quantum heat engines form an active field of research due to their potential applications. There are several phenomena that are unique to the quantum regime, some of which are known to give these engines an edge over their classical counterparts. In this work, we focus on the study of one and two-qubit finite-time Otto engines interacting with squeezed

Effects of GaN Buffer Resistance on the Device Performances of AlGaN/GaN HEMTs

open access: yesCrystals, 2020
We investigated the effects of GaN buffer resistance of AlGaN/GaN high-electron-mobility transistors (HEMTs) on direct current (DC), low-frequency noise (LFN), and pulsed I-V characterization performances.

Graph Repair and its Application to Meta-Modeling [PDF]

open access: yesEPTCS 330, 2020, pp. 13-34, 2020
Model repair is an essential topic in model-driven engineering. We present typed graph-repair programs for specific conditions; application to any typed graph yields a typed graph satisfying the condition. A model graph based on the Eclipse Modeling Framework (EMF), short EMF-model graph, is a typed graph satisfying some structural EMF-constraints ...
