The most striking successes in image retrieval using deep hashing have mostly involved discriminative models, which require labels. In this paper, we use binary generative adversarial networks (BGAN) to embed images to binary codes in an unsupervised way. By restricting the input noise variable of generative adversarial networks (GAN) to be binary and conditioned on the features of each input i...
The combination of super-resolution microscopy and synthetic fluorescence probes has emerged as a universal tool to monitor dynamic biological events at the nanometer scale. However, limited site-specificity fluorogenicity fluorescent make it still difficult realize long-term imaging. Herein, we introduce aggregation mediated SNAP-tag fluorogenic probe, BGAN-Aze, which can specifically bind var...
در این مقاله به طراحی عنصر سازنده یک آرایه آنتن 2×2 برای چرخش پرتو در سامانههایGPS و BGAN پرداخته شده است. عنصر مورد بررسی یک آنتن مارپیچ چهاربازویی چاپی (PQHA) است که در مد محوری کار میکند و برای تغذیه از یک شبکه یکپارچه با چرخش فاز ترتیبی °0، °90، °180 و °270 برای دستیابی به قطبش دایروی راستگرد (RHCP) بهره میبرد. آنتن مشخصات تشعشعی RHCP با خلوص بالا را تا محدودة زاویهای °60± =θ حفظ میکند...
BxGa1–xN films were deposited on 6H-SiC (0001) substrates at 1000°C by low pressure MOVPE using diborane, trimethylgallium, and ammonia as precursors. The presence of boron was detected by Auger scanning microprobe, the shift of the (00.2) x-ray diffraction peak, and low-temperature photoluminescence. A single-phase BxGa1–xN alloy with x = 1.5% was produced at the gas phase B/Ga ratio of 0.005....
We present the results of the performance evaluation of polarization-time coding and soft interference cancellation in multi-beam satellite systems a ected by co-channel interference in realistic setups. The standard of Broadband Global Area Network service (BGAN) has been considered as reference for the physical layer and realistic interference and channel models have been adopted. The work ha...
BGaN is an emerging ultrawide bandgap semiconductor with important applications ranging from power electronics to ultraviolet light emitters. To date, boron composition has been limited <10% in the wurtzite phase. Herein, a 200 nm thick high quality mixed-phase film was grown via horizontal–reactor metalorganic chemical vapor deposition exceeding 10%. The growth performed under low temperatu...
This paper presents an element of a 2×2-element array antenna for Inmarsat BGAN/GPS applications. The element is an axial mode printed quadrifilar helical antenna that has been integrated with a compact feed network to provide sequential phase rotation for circular polarization (CP) radiation. The novel integrated lumped-element feed network is designed to provide a balanced RF power to the fou...
