An AlGaAs/GaAs optical hetero-nipi modulator based on band filling effect with interdigital selective contacts has been fabricated by use of shadow mask molecular beam epitaxy (MBE) regrowth technique. There is a five order magnitude change in I-V characteristics from forward to reverse junction bias, which indicates the high quality contacts. The measured reflectance spectra show absorption coefficient about 7850 cm−1 an applied bias voltage as low 1.5 V.
Medication recommendation is one of the most critical health-related applications, which has attracted extensive research interest recently. Most existing works focus on a single hospital with abundant medical data. However, many small hospitals only have few records, hinders applying medication to real world. Thus, we seek explore more practical setting, i.e., multi-center recommendation. In this but total number records large. Though may benefit from affluent it also faced challenge that...
In this article, a 1 × 4 wideband, dual-polarized patch antenna array fed by novel, differentially structure is proposed. The of the was realized parallel line that printed on PCB and connected with inner outer conductors coaxial cable. This method elaborately solved problem narrow bandwidth conventional microstrip differential feeding. By using relatively thick air substrate (thickness = 0.19 λ0), stacked patches, coupling feeding structure, novel design, element introduced below operated...
In this paper, a co-aperture dual-polarized antenna array is proposed. The frequency band covers the P-band (0.4–0.7 GHz) and X-band (9.3–9.9 GHz). designed in form of an all-metal Vivaldi, while minimizing impact structure on electrical performance. final profile design for dual-band only 0.12 λ0 (λ0 corresponds to wavelength 0.4 adopts miniaturized waveguide slot structure, which can be well embedded structure. order verify feasibility scheme, prototype processing testing were carried out,...
The objective of this paper is to investigate the effect a passive control method on incipient cavitation mode around hydrofoil. Two micro vortex generators (mVGs) with different positions are installed leading edge (LE) NACA (National Advisory Committee for Aeronautics) 66 mVG-1 has same structural parameters as mVG-2, but it closer LE A high-speed camera used record transient behavior cavitating flow. large eddy simulation combined mass transport model applied analyze influence mechanism...
Annealing effects on the modulation structure of Bi1.6Pb0.4Sr2Ca2Cu3Ox superconductors were studied. It was found that upon annealing in flowing oxygen at 650 degrees C, changed from pure Pb-type, via mixed type, finally to Bi-type. When specimen subjected sequent nitrogen reversibly Bi-type type Pb-type. The change closely related loss or redistribution Pb ions. inhomogeneous distribution ions led modulation.
In this paper, a transient response improved output capacitorless low dropout regulator is designed in standard 0.13 $\mu$m CMOS technology. A method based on adaptively sense network (ASN) to increase the slew rate and provide extra discharge loop adopted, which suppresses undershoot overshoot of voltage. Simulation results reveal that voltage 97.03 mV 140.87 mV, when load current step from 10 $\mu$A 30 mA with edge time 100 ns, respectively. And recovery less than 0.35 $\mu$s, fast settle...
In this paper, a wide dynamic range RMS power detector with an operating frequency from 24 GHz to 35 mm-wave is presented. The fabricated in 65 nm CMOS process. It composed of unit, radio signal attenuator and linear proportional voltage adder. equalization technique used achieve good linearity performance. input the expanded by using one five units. simulation results show slope VOUT versus remaining constant at around 0.06 V/dBm when varies −10 dBm 10 dBm. difference output only 0.03 V 0...
