Abstract The recessive tall rice (Oryza sativa) mutant elongated uppermost internode (eui) is morphologically normal until its final elongates drastically at the heading stage. stage-specific developmental effect of eui mutation has been used in breeding hybrid to improve performance male sterile cultivars. We found that accumulated exceptionally large amounts biologically active gibberellins (GAs) internode. Map-based cloning revealed Eui gene encodes a previously uncharacterized cytochrome...
Uniform quasicubic α-Fe2O3 nanoparticles enclosed by six identical {110} planes were synthesized a simple solvothermal method. TEM investigations revealed that they formed through oriented attachment of primary nanocrystals assisted Ostwald ripening, and PVP surfactant played an important role in control over the final morphology products. These could catalyze oxidation almost 100% CO at temperature 230 °C, much lower than those nanophases with flowerlike, hollow, or other forms irregular...
Super hybrid rice varieties with ideal plant architecture (IPA) have been critical in enhancing food security worldwide. However, the molecular mechanisms underlying their improved yield remain unclear. Here, we report identification of a QTL, qWS8/ipa1-2D, super Yongyou12 (YY12) and related varieties. In-depth genetic characterization qWS8/ipa1-2D reveals that this newly identified QTL results from three distal naturally occurring tandem repeats upstream IPA1, key gene/locus previously...
Heat dissipation has emerged as a critical challenge in server cooling due to the escalating number of servers within data centers. The potential immersion jet technology be applied large-scale center operations remains unexplored. This paper introduces an innovative liquid system. primary objective is investigate synergistic integration and enhance heat capacity systems. By constructing single-server test bench, this study compares efficiencies pure systems examines impact inlet water...
Immersion cooling and jet impingement liquid cooling, as two of the significant emerging direct contact methods, have promising prospects for development application. The methods are combined numerical simulation is applied to study heat transfer performance immersion jet-cooled server. orthogonal method employed determine optimal structural parameters jet, flow characteristics under different inlet outlet layouts investigated. shows that dissipation effect moderate pressure achieved when...
The biosynthesis of antibiotics in bacteria is usually believed to be an intracellular process, at the end which matured compounds are exported outside cells. saframycin A (SFM-A), antitumor antibiotic, requires a cryptic fatty acyl chain guide construction pentacyclic tetrahydroisoquinoline scaffold; however, follow-up deacylation and deamination steps remain unknown. Herein we demonstrate that SfmE, membrane-bound peptidase, hydrolyzes release amino group; SfmCy2, secreted oxidoreductase...
Two scenarios of trains passing by each other are usually encountered, which in the tunnel and open air, respectively. The prototype CRH3 high speed train is considered present paper, with bogies, windshields, pantograph shrouds, air conditioner shrouds complex structures taking into consideration. Aerodynamic loads multi-body system response this discussed under conditions both scenarios. variations aerodynamic pressure on surface mainly analyzed, then formation mechanism discussed. A...
Cilia and flagella are conserved subcellular organelles, which arise from centrioles play critical roles in development reproduction of eukaryotes. Dysfunction cilia leads to life-threatening ciliopathies. HYLS1 is an evolutionarily centriole protein, for ciliogenesis, its mutation causes ciliopathy-hydrolethalus syndrome. However, the molecular function remains elusive. Here, we investigated formation using Drosophila model. We demonstrated that a basal body protein. Deletion led sensory...
This paper presents a convex programming algorithm based on modified Rodrigues parameters for six-degree-of-freedom asteroid powered landing trajectory design problem. The problem is formulated as nonconvex fuel-optimal control with nonlinear coupled translational and rotational dynamics, state constraints. In order to tackle the in convexification framework, original continuous-time optimization converted into discrete-time subproblem by linearizing discretizing dynamics effect of coupling...
