Abstract Auxin is central to many aspects of plant development; accordingly, plants have evolved several mechanisms regulate auxin levels, including de novo biosynthesis, degradation, and conjugation sugars amino acids. Here, we report the characterization an Arabidopsis thaliana mutant, IAA carboxyl methyltransferase1-dominant (iamt1-D), which displayed dramatic hyponastic leaf phenotypes caused by increased expression levels IAMT1 gene. encodes indole-3-acetic acid (IAA) methyltransferase...
Abstract Constructing highly twisted and rigid donor–acceptor systems is important for obtaining efficient thermally activated delayed fluorescence (TADF) emitters. In the traditional framework of structurally charge‐transfer TADF molecular design, increasing rigidity molecule through constructing groups guarantees minimized overlap integral between their highest occupied orbitals lowest unoccupied a small singlet triplet energy gap, which ensures reverse intersystem crossing. Increasing...
Abstract Bowman-Birk inhibitor (BBI) genes encode serine protease inhibitors that have repetitive cysteine-rich domains with reactive sites for the trypsin or chymotrypsin family. We identified seven BBI from japonica rice (Oryza sativa subsp. var Teqing). All of were found in a single cluster on southern end long arm chromosome 1. Four two domains, whereas one has truncated domain only site. also three novel genes, each which possesses instead two. In situ hybridization analyses indicated...
The compatibility of Au-free (Ti/Al/Ti/TiN) ohmic contacts in the gate-first double-metal (GFDM) process for AlGaN/GaN metal-insulator-semiconductor high-electron-mobility transistors (MIS-HEMTs) and Schottky barrier diodes (SBDs) on same 150-mm wafer was investigated discussed first time, including contact pretreatments, Al diffusion dielectric layers, vias (contact windows between two metal layers) etching conditions. All these steps are crucial to as well overall device fabrication...
A novel early gate dielectric AlGaN/GaN metal-insulator-semiconductor high-electron-mobility transistors (MIS-HEMTs) process is reported. With the highquality Si <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sub> N xmlns:xlink="http://www.w3.org/1999/xlink">4</sub> by low-pressure chemical vapor deposition and damage free, self-terminating passivation layer etching at area, MIS-HEMTs on 150-mm substrate demonstrate excellent output...
A novel out-of-plane MOEMS accelerometer based on near-field evanescent wave coupling by means of variable period subwavelength gratings has been proposed. First, the diffraction order number was calculated. Then, structure parameters were optimized finite element analysis to achieve high sensitivity in an ideal vibration mode. Results show that displacement at 2033 nm/G with a measurement range 0.12 G, corresponding first beam optical 0.46%/mG. Finally, we designed fabrication method form...
Abstract [Background] On January 7, 2020, the novel coronavirus named "COVID-19" aroused worldwide concern was identified by Chinese scientists. Many related research works were developed for emerging, rapidly evolving situation of this epidemic. This study aimed to analyze literatures on SARS, MERS and COVID-19 retrieve important information virologists, epidemiologist policy decision makers. [Methods] In study, we collected data from multi sources compared bibliometrics indices among...
Hollow and heterostructured architectures are recognized as an effective approach to improve photocatalytic performance. In this work, ternary TiO2/CdTe/BiOI with hollow structure was constructed via a step-by-step method. addition, the effect of TiO2 structural regulation energy band alignment BiOI CdTe quantum dots (CdTe QDs) in on dye removal were also studied. The results reveal that heterostructures substrates exhibit much higher activities than pure TiO2, P25, TiO2/CdTe, TiO2/BiOI...
The marked progress in MEMS/NEMS technology has demanded the development of a fundamental understanding cantilever-based sensing principles. One challenges detection is identifying and discerning most influenced parameters responsible for observed changes cantilever response. For example, effects various force fields such as those induced by atom/molecular adsorption variations temperature may occur simultaneously, increasing number that need to be concurrently measured ensure reliability...
This study explored the relations among and predictive effects of Chinese-learning motivation (CLM), use Chinese (UOC) proficiency on 218 international students' intercultural sensitivity (IS) to culture via a battery questionnaires. Major findings were: (a) respondents showed high CLM UOC were moderate in IS, (b) CLM, UOC, IS highly correlated with one another, (c) significantly positively predicted mediated IS. By providing new perspectives for this research enriched current literature.
In this paper, vertical GaN Schottky barrier diodes (SBDs) have been demonstrated on the freestanding (FS) wafer. Room temperature photoluminescence shows no emission of yellow luminescence, due to eliminating point defects (ON, VGa). The average full width half maximum (FWHM) value ω-scans for (0001) and (10–12) planes is 53 103 arcsec, respectively, as measured by high resolution X-ray diffraction; dislocation density at top surface cathodoluminescence ∼7.7 × 105 cm−2. SBDs fabricated...
