Abstract

Composite adaptive neural control of uncertain strict‐feedback systems is synthesized. It mainly consists of an adaptive neural backstepping controller, an immersion and invariance (I&I) update algorithm, and a set of state filters for conquering the in‐feasibility of the states' derivatives required in the update algorithm. For compensating the indefinite coupling terms in the update algorithm, a novel nonlinear σ$$ \sigma $$‐modification method is promoted. To further tackle the case with unknown input gain functions, the dynamic surface control (DSC) and the adding‐an‐integrator technique are incorporated for preventing the so‐called explosion of complexity and the algebraic‐loop problems in the virtual controller and the composite update algorithm, respectively. The proposed design ensures the semi‐globally uniformly ultimately bounded (SGUUB) stability of the closed‐loop system and, in particular, the convergence of prediction errors to the vicinity of zero without persistent excitation (PE), which in turn improves the tracking performance.

Abstract

Objectives: To investigate the prevalence and molecular characteristics of fosA3 and fosA7 among Salmonella isolates.Methods: Five hundred and fifty-one Salmonella isolates collected from food animals in China during 2016-19 were screened for fos genes. The drug resistance, serovars, clonal relationships and genetic environments of fosA were compared between fosA7- and fosA3-positive Salmonella.Results: A relatively high prevalence of fosA7 (9.26%) and fosA3 (6.53%) was identified. fosA3 was associated with high-level fosfomycin resistance (≥512 mg/L), while fosA7 conferred relatively low-level resistance that was independent of the presence of glucose-6-phosphate. Additionally, fosA7 could facilitate Salmonella survival under oxidative stress. Both fosA3 and fosA7 were found in diverse serovars and STs, but segregated into distinct groups. The fosA3-positive Salmonella Typhimurium/Salmonella Indiana strains showed close genetic relationships, while fosA7-positive Salmonella Meleagridis/Salmonella Agona/Salmonella Derby showed a relatively high degree of whole-genome sequence heterogeneity. fosA3 was located on conjugative IncHI2 plasmids or chromosomes, while fosA7 was strictly chromosomal. Furthermore, two strains carried large chromosomal fosA7 regions within genomic islands. The fosA3 and fosA7 contigs from our isolates and the NCBI could be segregated into four primary and distinct genomic backbones. IS26 and the antibiotic resistance genes (ARGs) blaCTX-M, blaTEM-1B and rmtB were frequently adjacent to fosA3, while fosA7-carrying contigs generally lacked mobile elements and ARGs.Conclusions: fosA3 and fosA7 were the primary factors contributing to reduced fosfomycin susceptibility, to different degrees, in these Salmonella isolates. The distinct distributions and molecular characteristics of fosA7 and fosA3 indicated that their origin and evolution in Salmonella were most likely distinct. [ABSTRACT FROM AUTHOR]

Abstract

A novel hemi-cylindrical (HC) 3D NAND Flash architecture is demonstrated for the first time. HC 3D NAND squeezes the gate-all-around (GAA) hole in one direction, followed by a slit cut to split the GAA device to produce twin cells. It creates ~ 2.6 times of memory density increase than standard GAA 3D NAND at the same stacking layer. Both experimental and simulation results clarify that the "non-local" effect of channel potential can essentially "smooth" the non-uniform curvature effect thus the HC 3D NAND device possesses regular P/E window characteristics even it is not a regular shape of GAA. Good 100K PE cycling endurance and post 10K-cycled 150C retention are demonstrated. HC 3D NAND structure has potential to further scale 3D NAND device in lateral dimension, with the advances of processing technologies.

Abstract

A thermal emitter with selective wavelength has been demonstrated in which the dielectric layers formed one-dimensional photonic crystals are sandwiched between two Ag films. The top Ag film is perforated periodically with hexagonal hole array. The selected thermal radiation of the photonic crystals resonates between two metal films and surface plasmon polaritons are generated on the top Ag and converted to light radiation. It is found that when leakage modes adjacent to the optic band gap of photonic crystals meet the resonant modes of surface plasmom polaritons, an enhanced thermal emission with maximum intensity can be obtained. The hybrid photonic and plasmonic thermal emitters are selective, which should be very useful for the creation of high power infrared light sources. [ABSTRACT FROM AUTHOR]

Abstract

The irradiance reflectance just beneath the water surface is closely related to the absorption coefficient,scattering coefficient and solar zenith angle.However,the effect of solar zenith angle on the irradiance reflectance just beneath the water surface is not clear in Lake Taihu.The influence factors of irradiance reflectance just beneath the water surface in Lake Taihu were analyzed based on the optical parameters and numerical simulates using the data of total 27 sampling sites measured in May,2010.The results show that while solar zenith angle is in the range of 0°-25°and 70°-89°,it has little influence on the growth of irradiance reflectance just beneath the water surface which is less than 10%.While solar zenith angle is in the range of 30°-70°,the growth of irradiance reflectance is 13.13%-52.19%.The correlation of theoretical results and measured data show that such numerical study is correct for Lake Taihu.Therefore,full consideration should be given to the effect of solar zenith angle when studying on the optical properties of water and the driving mechanism of the light to aquatic ecosystems.

Abstract

We demonstrate a novel vertical channel 3D NAND Flash architecture — SGVC. SGVC device is a single-gate, flat-channel TFT charge-trapping device with ultra-thin body. Our novel array decoding method enables a tight-pitch (25nm HP) metal BL design to fulfill the large page size (16KB for one plane) for high-performance NAND product. The SGVC flat cell possesses excellent P/E window of ∼10V, small X/Y/Z adjacent-cell interferences, good self-boosting inhibit, and >10K P/E cycling endurance. Due to the advantage of flat cell that is insensitive to etching CD, SGVC device is tolerant to the non-ideal vertical etching and has shown excellent device uniformity from layer to layer. In sharp contract to GAA VC, SGVC suffers no penalty from field-enhancement effect, thus has shown very robust read-disturb immunity against long-term gate stressing. Due to (1) two physical bits per X-Y cell footprint, and (2) efficient array design with minimal overhead, SGVC architecture has 2 to 4 times memory density than GAA VC 3D NAND at the same stacking layer number.

Abstract

The reflection and emission spectra of Ag/SiO2/Ag trilayer plasmonic thermal emitters with different SiO2 thicknesses are investigated. The top Ag film is perforated with periodic slits. It is found that the coupling of surface plasmons at the top and bottom Ag/SiO2 interface results in the redshift in thermal emission peaks. In this Ag/SiO2/Ag plasmonic thermal emitter, the electromagnetic field exhibits either Fabry–Pérot resonance or propagating surface plasmons depending on the thickness of SiO2 layer. By varying the thickness of SiO2 layer, transition from localized to grating-coupled propagating surface plasmon modes is observed. [ABSTRACT FROM AUTHOR]
