Scalable Bell inequalities for multiqubit systems
Based on Clauser-Horner-Shimony-Holt inequality, we show a fruitful method to
exploit Bell inequalities for multipartite qubit systems. These Bell
inequalities are designed with a simpler architecture tailored to experimental
demonstration. Under the optimal setting we derive a set of compact Mermin-type
inequalities and discuss quantum violations for generalized
Greenberger-Horne-Zeilinger (GGHZ) states. Also, we reveal relationship between
quantum nonlocality and four-partite entanglement for four-qubit GGHZ states.Comment: 4 pages, 1 figur
Research on the Demand Forecasting Method of Sichuan Social Logistics Based on Positive Weight Combination
The macro-social logistics demand forecast is of great strategic significance to optimize the national or regional economic structure, improve the investment environment and improve the overall competitiveness of regional economy. In this study, the total amount of social logistics in Sichuan province was selected to reflect the social logistics demand, the factors influencing the social logistics demand in Sichuan province were analyzed, and eight economic indicators were summarized. This study first USES the time series prediction model (including the time response model GM (1, 1)), an exponential smoothing model, causal relation model (including multidimensional prediction model GM (1, n) and BP neural network model), to build four methods combination model, weight given solution of linear programming each forecast model, the forecasting result of combination forecast model deviation is minimal. The posterior difference test was applied to the above five models to compare the prediction results of each prediction method
A Continuous Dual-Axis Atomic Interferometric Inertial Sensor
We present an interferometric inertial sensor that utilizes two
counter-propagating atomic beams with transverse two-dimensional cooling. By
employing three parallel and spatially aligned Raman laser beams for
Doppler-sensitive Raman transitions, we successfully generate inertia-sensitive
Mach-Zehnder interference fringes with an interrogation length of
. The measured rotation and acceleration sensitivities are
and ,
respectively. The sensor's capability to measure rotation and acceleration
simultaneously in dynamic environments is validated through comparative
analysis with classical sensors under force oscillation in different
directions. Additionally, we conduct experiments on a turntable to calibrate
the gyroscope's scaling factor and address nonlinearity.Comment: 8 pages, 4 figure

Two variants on T2DM susceptible gene HHEX are associated with CRC risk in a Chinese population
Increasing amounts of evidence has demonstrated that T2DM (Type 2 Diabetes Mellitus) patients have increased susceptibility to CRC (colorectal cancer). As HHEX is a recognized susceptibility gene in T2DM, this work was focused on two SNPs in HHEX, rs1111875 and rs7923837, to study their association with CRC. T2DM patients without CRC (T2DM-only, n=300), T2DM with CRC (T2DM/CRC, n=135), cancer-free controls (Control, n=570), and CRC without T2DM (CRC-only, n=642) cases were enrolled. DNA samples were extracted from the peripheral blood leukocytes of the patients and sequenced by direct sequencing. The χ(2) test was used to compare categorical data. We found that in T2DM patients, rs1111875 but not the rs7923837 in HHEX gene was associated with the occurrence of CRC (p= 0.006). for rs1111875, TC/CC patients had an increased risk of CRC (p=0.019, OR=1.592, 95%CI=1.046-2.423). Moreover, our results also indicated that the two variants of HEEX gene could be risk factors for CRC in general population, independent on T2DM (p< 0.001 for rs1111875, p=0.001 for rs7923837). For rs1111875, increased risk of CRC was observed in TC or TC/CC than CC individuals (p<0.001, OR= 1.780, 95%CI= 1.385-2.287; p<0.001, OR= 1.695, 95%CI= 1.335-2.152). For rs7923837, increased CRC risk was observed in AG, GG, and AG/GG than AA individuals (p< 0.001, OR= 1.520, 95%CI= 1.200-1.924; p=0.036, OR= 1.739, 95%CI= 0.989-3.058; p< 0.001, OR= 1.540, 95%CI= 1.225-1.936). This finding highlights the potentially functional alteration with HHEX rs1111875 and rs7923837 polymorphisms may increase CRC susceptibility. Risk effects and the functional impact of these polymorphisms need further validation
