A 60 GSa/s THA is designed and realized in InP-DHBT process. The THA presents a small signal bandwidth of 50 GHz. For +4 dBm and -4 dBm input powers, 60 GSa/s spectral measurements give a THD of -37.3 dB and -51.3 dB for input frequency up to 2 GHz and a THD of -30.1 dB and -38.7 dB up to 15 GHz. Temporal...

With 2 mol% Al3+ ions and 8 mol% Eu3+ ions co-doping,nano-size[K0.8Y0.63Eu3+0.08Al0.02][Mo0.2W0.8O4] phosphor was synthesized by the sol-gel method. Through XRD, DTA-TG, SEM and photoluminescent analysis, its morphology, crystal structure and luminescent property were discussed and it is found that one...

The acquisition of uncompressed video streams over Ether- net on FPGA platforms constitutes a substantial design challenge, primarily due to real-time bandwidth requirements and the susceptibility of packet-based transmission to jitter and synchronization errors. FIFO buffers have a critical role in...

In order to find an effective secret key generation scheme in wireless networks, many based on received signal strength methods have been proposed. However, the secret bit rates of existing schemes are relatively low. To resolve the problem of low generation rate, a vector quantization scheme is proposed...

The paper is concerned with measuring of risks in managerial decision-making. It builds upon the uncertainty of economic information, which is converted into the concept of risk expressed in terms of probability and using confidence intervals and standard deviations of the predicted quantities. The paper...

For the weakness of the existing predistortion algorithm, when large amplitude component in the modulation signal which is more than the voltage in saturation will be limited, leading to predistortion algorithm become invalid, and a new joint RF power amplifier (PA) linearization method is proposed....

The Programmed Cell Death 1 (PD-1)/Programmed Death Ligand 1 (PD-L1) Immune Checkpoint Inhibitors (ICIs), have become a hot spot in the field of cancer research and treatment, and bring new hope to patients with advanced tumors. But, in addition to enhancing the anti-tumor effect of T cells, PD-1/PD-L1...

During the process of drilling, the drill bit makes direct contact with the engineering rock mass, and the feedback from the drill bit effectively represents the mechanical properties of the rock mass. Digital drilling technology allows for the real-time monitoring of key parameters such as rotational...

This paper adopts the melt blending method for organic silicon resin/nano Al2O3 and PF. The organic silicon resin in the blending resin cures and forms interpenetrating network structures to improve the heat resistance of PF plastics. TG, DSC and FESEM analysis characterize the changes in heat resistance...

China’s assertiveness in the East and South China Sea (ESCS), complemented with paradoxical behavior on promoting international maritime cooperation, has left many to conclude that Beijing uses a dual strategy. To expand China’s foreign policy’s interpretation, we present an alternative approach with...

Abstract. Objective: To observe and analyze the application value in clinical diagnosis of the diabetes patients with blood lipid inspection. Methods: From June 2013 to June 2014 we select 50 patients with diabetes and 50 healthy people in physical examination as the research object, they can be divided...

In an ultra-high-frequency (UHF) radio frequency identification (RFID) system, direct separation for tag collision on a physical layer can improve the efficiency of the tag identification. Many coding methods can be adopted in the RFID system. Different codes have different link frequencies and have...

The adsorption and binding mechanisms of chloride ion in sea sand mortars were investigated through measuring the water-soluble chloride ion content in this paper. In addition,the microstructure of Friedel's salt were characterized by three approaches : X-ray diffraction (XRD), thermal analysis method...

Quadrature index spatial modulation (QISM) with two constellations is presented to exploit the potential spatial diversity gain from spatial domain in multiple input multiple output (MIMO) channel system. In this paper, we consider a transmitted spatial vector formed by mapping two constellations symbol...

Photocatalysis is a green technology that plays a vital role in achieving sustainable development goals and ensuring a clean environment. Metal oxide materials, in particular, have gained tremendous attention for their versatility in fields such as catalysis, semiconductors, ceramics, sensors, and energy...

Sepsis is a life-threatening organ dysfunction caused by a deregulated host response to infection, and is the most common cause of death in the intensive care unit. Although the pathogenesis of sepsis has made substantial progress, the current clinical treatment of sepsis is basically symptomatic treatment,...

In a standard Evolutionary Algorithms (EAs), one uses the same rate for mutations from bit 1 to bit 0 and its reverse direction. There are many reports that the asymmetric mutation model is a very powerful strategy in EAs to obtain better solutions more efficiently. In this paper, we report stochastic...
