A quantum random number generator (QRNG) can generate true randomness by exploiting the fundamental indeterminism of quantum mechanics. Most approaches to QRNG employ single-photon detection technologies and are limited in speed. Here, we experimentally demonstrate an ultrafast QRNG at a rate over 6 Gbits/s based on the quantum phase fluctuations of a laser(More)
Many studies have shown that zinc deficiency not only retards growth, but also affects several brain functions, including learning and memory. However, the underlying mechanism of impaired hippocampus-dependent learning and memory under zinc deficiency is poorly understood. In this study, young mice were fed a zinc-deficient diet (0.85 ppm) for 5 weeks.(More)
The methylenetetrahydrofolate reductase (MTHFR) gene variant C677T is suspected to be a risk factor for psychiatric disorders, but it remains uncertain whether the MTHFR C677T variant is associated with bipolar disorders. To investigate possible association, unrelated controls (n=461) with no history of psychiatric disorders and patients (n=501) diagnosed(More)
According to the characteristic of Human Visual System and the association memory ability of neural network, an adaptive image watermarking algorithm based on neural network is proposed. The watermarking signal is embedded in higher frequency, which is in the lower frequency of original image by DWT joined with DCT. The ability of attracting is improved by(More)
With the development of Internet of Things (IOT), Radio Frequency Identification (RFID) is a hot topic in recent years. However, the traditional RFID reader system has some drawbacks, such as the effective reading distance of the reader is very small, and the reading speed of the reader is very slow. In this paper, we propose a novel RFID reader system(More)
Application of terrain-vehicle mechanics for determination and prediction of mobility performance of autonomous wheeled mobile robot (AWMR) in rough terrain is a new research area currently receiving much attention for both terrestrial and planetary missions due to its significant role in design, evaluation, optimization, and motion control of AWMRs. In(More)
It is well-known that zinc deficiency leads to neuronal death in the brain. Here we tested the hypothesis that changes in the TrkB signaling pathway are involved in hippocampal neuronal apoptosis of suckling offspring with maternal zinc deficiency. Postpartum mice were fed a zinc-deficient (0.85 ppm) diet and their offspring were used as a lactational zinc(More)
performance has become a state-of-the-art research topic. The concept of collaborative BCIs, which aimed to use multi-brain computing to enhance human performance, was proposed recently. To further study the feasibility of collaborative BCIs, here we propose to develop an online collaborative BCI to accelerate human response to visual target stimuli by(More)
