Electromagnetic orbital angular momentum (OAM) has attracted a lot of interest recently in the field communication systems. OAM-carrying radio beams can be generated and detected by several devices. In this paper, we use circular phased antenna array to generate that possess ring-shaped intensities helical phase fronts. We also propose validate system uses OAM-based multiplexing. A is used superimposed OAMmode using appropriate excitation settings. The transmission characteristics OAM modes...
With the development of high-resolution radar satellite for global comprehensive environmental monitoring, day-and-night and all-weather surveillance has become an active growing research field. However, in all cases, these applications require to have a high-efficiency module (e.g., T/R module), high system transmitting power. These requirements may put important limitation on performance with high-power configuration. In this paper, we report novel waveform optimization framework. Through...
Background The Hippo/MST1 signaling pathway plays an important role in the regulation of cell proliferation and apoptosis. As a major downstream target pathway, YAP2 (Yes-associated protein 2) functions as transcriptional cofactor that has been implicated many biological processes, including organ size control cancer development. MST1/Lats kinase inhibits YAP2's nuclear accumulation activity through inducing phosphorylation at serine 127 sequential association with 14-3-3 proteins. However,...
The next generation of spaceborne synthetic aperture radar (SAR) remote sensing systems will emphasize on high-resolution and wide-coverage imaging. For these design goals, digital beamforming (DBF) in elevation is a promising candidate. DBF-SAR can provide global monitoring capacity for the continuous observation highly dynamic rapidly changing world with high spatial resolution short repeat intervals. A experiment regarding real complex scene wave propagation channel effects remains...
In the Earth observation mission of synthetic aperture radar (SAR), wide swath can be used to complete global monitoring in a short time and high resolution provide rich detailed information about feature space prominent structure texture. However, traditional single-channel classical SAR system cannot meet high-resolution wide-swath (HRWS) imaging demand due constraint minimum antenna area. Fortunately, this fundamental limitation overcome by using multiple receive subapertures combination...
42CrMo heat-resistant steel is a kind of structural steel, which widely used in components such as crane weight-on-wheel, automobile crank shaft, locomotive gear hub and so on, for its good hardening ability, high temperature strength, creep resistance, little quenching deformation.However, industry application, mismatching between the strength toughness always occurs structure components.In order to solve problem that does not match manufacturing process polar nuclear power station, effect...
Digital beamforming (DBF) with scan-on-receive (SCORE) technique in elevation is a powerful that enables spaceborne synthetic aperture radar (SAR) to achieve high-resolution wide swath (HRWS) imaging. In the DBF-SAR system, sampling signals from each channel are weighted by weights generated digital signal processing system real-time. However, contradiction between shortage of hardware resources and resource demand multichannel real-time increases difficulty design. order solve this problem,...
Synthetic aperture radar (SAR) images require a high-resolution system for accurate interpretations. This high range resolution can be achieved by stepped frequency chirp signals. To reconstruct wideband waveform from each subband signal, amplitude/phase/delay imbalance between the channels should precisely compensated. In this paper, configuration is first presented. Further, calibration strategy was proposed based on three loops: reference calibration, transmitting and receiving loops...
TP63 plays an essential role in the development of epidermis and skin appendages. Mutations can give rise to a series syndromes characterized by various combinations ectodermal dysplasia, limb malformations, orofacial clefting many populations. To test whether is disease-causative gene for these phenotypes Chinese, we recruited two Chinese Ectrodactyly-Ectodermal-dysplasia-Cleft lip/palate syndrome (EEC) cases Limb-Mammary-Syndrome (LMS) patient carry out sequencing. Three missense mutation,...
