Conference Proceeding
This article first introduces the research background and working principle of the TX phase alignment function of the Virtex-7 series FPGA. Then, according to the application requirements of the PCIe ...protocol, a design scheme for 12-channel bonding based on the GTH IP core is proposed. This solution solves the traditional High-speed serial transceivers only support up to eight channel bonding problems. The simulation results and board-level verification results of the solution show that the solution can stably achieve 12-channel bonding, and at the same time, the link bandwidth can be expanded to 1.5 times.

The Chinese CubeSat Mission, Gamma Ray Integrated Detectors (GRID), recently detected its first gamma-ray burst, GRB 210121A, which was jointly observed by the Gravitational wave high-energy ...Electromagnetic Counterpart All-sky Monitor (GECAM). This burst is confirmed by several other missions, including \fermi and \textit{Insight}-HXMT. We combined multi-mission observational data and performed a comprehensive analysis of the burst's temporal and spectral properties. Our results show that the burst is relatively special in its high peak energy, thermal-like low energy indices, and large fluence. By putting it to the \(E_{\rm p}\)-\(E_{\rm\gamma, iso}\) relation diagram with assumed distance, we found this burst can be constrained at the redshift range of 0.3,3.0. The thermal spectral component is also confirmed by the direct fit of the physical models to the observed spectra. Interestingly, the physical photosphere model also constrained a redshift of \(z\sim\) 0.3 for this burst, which help us to identify a host galaxy candidate at such a distance within the location error box. Assuming the host galaxy is real, we found the burst can be best explained by the photosphere emission of a typical fireball with an initial radius of \(r_0\sim\) 3.2 \(\times 10^7\) cm.
To understand the distribution and diffusion of Oncomelania hupensis snails in the Baoying and Gaoyou sections of the Li Canal in the east route of the South-to-North Water Diversion Project.
The ...retrospective survey method was used to investigate the distribution and diffusion of snails in the Baoying and Gaoyou sections of the Li Canal, the conventional survey and the methods of salvage of water and attracting snails were used to detect the distribution of snails in river banks and water.
The earliest findings of snails in the Gaoyou section of the Li Canal was in 1955, the northernmost distribution of snails was Dilong ferry at the west dam and east slope of the Li Canal. The dynamic surveillance in the Gaoyou section of the Li Canal from 2001 to 2010 showed that the snail status was of low density and low fluctuation of area, and the distribution range was 119 degrees 24' 36" -119 degrees 25' 34", 32 degrees 48' 30" -32 degrees 54' 05". From 2006 to 2010, the snails were not found by the methods of salvag
To investigate the factors affecting the result and selection of local excision for low rectal cancer.
The clinical data of 101 patients with low rectal cancer treated by local excision were ...retrospectively analyzed. Survival was estimated using the Kaplan-Meier. The factors influencing on the survival were analyzed using univariate (Log rank) and multivariate (Cox model) analysis methods.
Of 101 patients in this series, 91 patients underwent transanal excision, 9 had transsacral excision, 1 recieved transvaginal excision. Postopertative complication developed in 6 patients (5.9%). No death occurred within 30 postoperative days. Five T4 patients underwent preoperative radiotherapy, and 34 received postoperative radiotherapy. The overall 5-year survival rate was 91.0% for the whole group, and it was 100%, 92.6%, 77.1%, 83.3% for patients with Tis, T1, T2, and T3/T4 lesion, respectively. The incidence of local recurrence was 15. 8%. Univariate analysis revealed that pathological T stage, tumor size (> 3 cm), ly
Since the true ground state of the hadrons may be strange quark matter (SQM), pulsars may actually be strange stars rather than neutron stars. According to this SQM hypothesis, strange planets can ...also stably exist. The density of normal matter planets can hardly be higher than 30 g cm\(^{-3}\). As a result, they will be tidally disrupted when its orbital radius is less than \(\sim 5.6\times10^{10} \rm \, cm \), or when the orbital period (\(P_{\rm orb}\)) is less than \( \sim \rm 6100\, s \). On the contrary, a strange planet can safely survive even when it is very close to the host, due to its high density. The feature can help us identify SQM objects. In this study, we have tried to search for SQM objects among close-in exoplanets orbiting around pulsars. Encouragingly, it is found that four pulsar planets (XTE J1807-294 b, XTE J1751-305 b, PSR 0636 b, PSR J1807-2459A b) completely meet the criteria of \(P_{\rm orb} < \rm 6100\, s \), and are thus good candidates for SQM planets. The orbital periods of two other planets (PSR J1719+14 b and PSR J2051-0827 b) are only slightly higher than the criteria. They could be regarded as potential candidates. Additionally, we find that the periods of five white dwarf planets (GP Com b, V396 Hya b, J1433 b, WD 0137-349 b, and SDSS J1411+2009 b) are less than 0.1 days. We argue that they might also be SQM planets. It is further found that the persistent gravitational wave emissions from at least three of these close-in planetary systems are detectable to LISA. More encouragingly, the advanced LIGO and Einstein Telescope are able to detect the gravitational wave bursts produced by the merger events of such SQM planetary systems, which will provide a unique test for the SQM hypothesis.
Reference-frame-independent measurement-device-independent quantum key distribution (RFI-MDI-QKD) is a novel protocol which eliminates all possible attacks on detector side and necessity of ...reference-frame alignment in source sides. However, its performance may degrade notably due to statistical fluctuations, since more parameters, e.g. yields and error rates for mismatched-basis events, must be accumulated to monitor the security. In this work, we find that the original decoy-states method estimates these yields over pessimistically since it ignores the potential relations between different bases. Through processing parameters of different bases jointly, the performance of RFI-MDI-QKD is greatly improved in terms of secret key rate and achievable distance when statistical fluctuations are considered. Our results pave an avenue towards practical RFI-MDI-QKD.
