TL;DR: The rust resistance and novel agronomic traits revealed that the wheat–Thinopyrum substitution lines will be potentially useful for genetic improvement of wheat.
Abstract: Two wheat–Thinopyrum substitution lines X479 and X482 selected from the progenies of wheat “Mianyang26 (MY26)” × wheat–Thinopyrum intermedium ssp. trichophorum partial amphiploid were characterized by seed storage protein electrophoresis, genomic in situ hybridization (GISH), fluorescence in situ hybridization (FISH), and PCR-based molecular markers. Seed storage protein analysis showed that X479 expressed some of Th. intermedium ssp. trichophorum-specific gliadin and glutenin bands. Chromosome counting and GISH probed by Pseudoroegneria spicata genomic DNA indicated that two pairs of Thinopyrum-derived chromosomes (St genome and St–JS translocated chromosomes) substituted for two pairs of wheat chromosomes in both X479 and X482. FISH using pAs1 and pHvG38 as probes showed that chromosomes 1B and 4B, and 4D and 6D were absent in X479 and X482, respectively. Using the newly isolated JS chromosome-specific repetitive sequence pDb12H as a probe, the FISH signals revealed that the translocation of St–JS chromosomes in X479 and X482 occurred in repetitive sequence regions of the short arm. The molecular markers based on wheat–rice colinearity confirmed that the chromosome constitutions of X479 and X482 were 1St (1B) + 4St–4JS (4B) and 4St–JS (4D) + 6St (6D), respectively. The substitution lines were both fully fertile which suggests that the Th. intermedium chromosomes in X479 and X482 substitute well for the corresponding wheat chromosomes. The rust resistance and novel agronomic traits revealed that the substitution lines will be potentially useful for genetic improvement of wheat.

TL;DR: In this article, a microwave photonic intensity differentiator based on a Kerr optical comb generated by a compact integrated micro-ring resonator (MRR) is proposed and experimentally demonstrated.
Abstract: We propose and experimentally demonstrate a microwave photonic intensity differentiator based on a Kerr optical comb generated by a compact integrated micro-ring resonator (MRR). The on-chip Kerr optical comb, containing a large number of comb lines, serves as a high-performance multi-wavelength source for implementing a transversal filter, which will greatly reduce the cost, size, and complexity of the system. Moreover, owing to the compactness of the integrated MRR, frequency spacings of up to 200-GHz can be achieved, enabling a potential operation bandwidth of over 100 GHz. By programming and shaping individual comb lines according to calculated tap weights, a reconfigurable intensity differentiator with variable differentiation orders can be realized. The operation principle is theoretically analyzed, and experimental demonstrations of the first-, second-, and third-order differentiation functions based on this principle are presented. The radio frequency amplitude and phase responses of multi-order intensity differentiations are characterized, and system demonstrations of real-time differentiations for a Gaussian input signal are also performed. The experimental results show good agreement with theory, confirming the effectiveness of our approach.

TL;DR: This active composite metamaterial modulator is the first to achieve a 1 GHz modulation speed and 85% modulation depth during real-time dynamic tests and is the basis for the development of effective and ultrafast dynamic devices for THz wireless communication and imaging systems.
Abstract: The past few decades have witnessed a substantial increase in terahertz (THz) research. Utilizing THz waves to transmit communication and imaging data has created a high demand for phase and amplitude modulation. However, current active THz devices, including modulators and switches, still cannot meet THz system demands. Double-channel heterostructures, an alternative semiconductor system, can support nanoscale two-dimensional electron gases (2DEGs) with high carrier concentration and mobility and provide a new way to develop active THz devices. In this Letter, we present a composite metamaterial structure that combines an equivalent collective dipolar array with a double-channel heterostructure to obtain an effective, ultrafast, and all-electronic grid-controlled THz modulator. Electrical control allows for resonant mode conversion between two different dipolar resonances in the active device, which significantly improves the modulation speed and depth. This THz modulator is the first to achieve a 1 GHz ...

TL;DR: The results demonstrate the potential of the graphene-ZnO hybrid nanocomposites as an electrode in high-performance supercapacitors.
Abstract: In this paper, we report a facile low-cost synthesis of the graphene-ZnO hybrid nanocomposites for solid-state supercapacitors. Structural analysis revealed a homogeneous distribution of ZnO nanorods that are inserted in graphene nanosheets, forming a sandwiched architecture. The material exhibited a high specific capacitance of 156 F g−1 at a scan rate of 5 mV.s−1. The fabricated solid-state supercapacitor device using these graphene-ZnO hybrid nanocomposites exhibits good supercapacitive performance and long-term cycle stability. The improved supercapacitance property of these materials could be ascribed to the increased conductivity of ZnO and better utilization of graphene. These results demonstrate the potential of the graphene-ZnO hybrid nanocomposites as an electrode in high-performance supercapacitors.
