Four Hypotheses About the Different Possibility Between Actual and Theoretic Haemophilia Incidence
Authors: Ning Ke 
Published: June 2020

Abstract
Haemophilia is a disease caused by the lack of clotting factors in the blood. Currently, the only treatment is blood transfusion. To avoid this situation, patients need to do blood transfusion periodically to ensure they have enough clotting factors. Otherwise, hemophilia is an X-chromosome disease so that X-chromosome inactivation may play a role in inheriting. Theoretically, the incidence of female carriers is 50%, but in fact, it is not. There are four hypotheses to help to explain the weird phenomenon. Also, these four hypothesis could probably inspire people some new treatments of hemophilia. The first explanation is about chromosome leaking, which means not all of the genes on the silenced chromosome get silenced, a small part of genes can still be expressed. The second hypothesis is X-chromosome biased selection, which means that X-chromosomes chosen is not randomly. It tends to silence the chromosome with hemophilia genes, not another one. The third guess is key regulators, which can adjust the X-chromosome inactivation so that it ensures the X-chromosome with hemophilia genes gets silenced. Afterward, the fourth one is about the mosaic, which talks about the majority part of cells working like the normal cells to produce clotting factors. In conclusion, the ratio is not half to half might be caused by these four hypothesis.

Abstract
With the large-scale penetration of renewable energy, the safe and stable operation of power grid and economic dispatch are facing great challenges. How to realize accurate perception of internal load characteristics of power users is an important technical difficulty to support power demand side management. For this reason, this article is based on extensive IOT technology in electricity, and a non-invasive power load monitoring method (NILM) based on cloud edge collaboration is proposed. Through the two-level architecture of “edge identification” and “cloud correction”, the method effectively overcomes the contradiction between the weak computing capability of edge terminal and the heavy communication pressure of cloud master station. The experimental results show that the method can effectively improve the accuracy and reliability of traditional NILM method by considering the influence of external factors.

Abstract
With the proposal of ubiquitous electric power internet of things, the power industry’s demand for communication network is more and more intense, and the development of power wireless private network also puts forward higher requirements and more stringent standards for the wireless communication technology involved in it. Therefore, a spectrum sensing technology for 230MHz power wireless private network is proposed in this paper. By taking advantage of the relationship between the two threshold values and the signal-to-noise ratio, adjustment factors are set to achieve different two threshold values corresponding to different signal-to-noise ratios on the premise of avoiding frequent adjustment of threshold values. On the one hand, when the channel condition is good, the distance between the double threshold is reduced also reduce the system computation. On the other hand, when the channel condition is poor, the distance between the double threshold is increased to increase the extraction opportunity of the trust function, so as to improve the detection probability of the system. Finally, experimental results show that the proposed algorithm can effectively improve the communication performance of 230MHz power wireless private network.

Authors: Hongyi Zhao 
Published: June 2020

Abstract
It is important that carrying out field lightning shock withstand voltage test can ensure the safe operation of gas insulated switch. The insulation condition of GIS can be comprehensively evaluated by detecting partial discharge (PD) during the field shock withstand voltage test. In this paper, the partial discharge characteristics of a gas insulated switch salient defect under lightning impulse voltage with different oscillation frequencies are studied. According to the experimental results, when the oscillation frequency is low, the PD value of the system increases significantly, but the PDIV50 value of OLI voltage is low. As the oscillation frequency of OLI voltage increases, PDIV50 increases and the number of partial discharge decreases.

Nanofluid has drawngreatattentionas a new efficientenergy carrier for improving heat-transfer and combustionperformance. However, universalconsensus has not been reached on the mechanism of nanoparticlesinfluencing atomization and combustion. In this paper, the focus was thecavitation of Al2O3-H2O nanofluids inside and outside a nozzle with circular cross section. Comprehensive analyses of flow morphology were carried out based on a highspeed-macro shadow imaging system. The effects of nanoparticles on the initial development of round jet, incipient cavitation and supercavitation inside sharp-edge nozzle, and jet cavitationoutside round-edge nozzle were discussed. Results showed that: nanoparticles accelerated the formation of cavitation inside the nozzle, and reduced the critical supercavitation pressure. Meanwhile, they promoted the formation and persistence of bubbles in liquid jet. These bubbles generated near the KH-instability wave peaks below the nozzle. Compared with that of basic fluid, the wavelocationof nanofluid jet was closer to the nozzle exit. In conclusion, the addition of nanoparticlespromoted the cavitation inside and outside the nozzle.Itcan be attributed tothe following changes: nanoparticles increased the original adsorption of air, reduced the tensile strength of liquid, speeded up the disturbances of jet, and played the role of heterogeneous nucleation points.

Abstract
In the process of dehumidification and regeneration, a complicated heat and mass transfer process occurred between air and hygroscopic materials in desiccant wheel. The performance of dehumidifier is affected by the air inlet state parameters, regeneration air inlet state, air flow, regeneration air flow, and wheel speed and many other factors.Based on the conservation of water mass and energy in the gas region of the desiccant wheel and the conservation of water mass and energy in the solid region, a differential equation describing the absorption and regeneration processes in the wheel is established. In addition to necessary boundary conditions and supplementary equations, a complete mathematical model of desiccant wheel is developed.Numerical solution of mathematical model can be obtained by using finite difference method, which can be used in calculation of actual process and optimization analysis of wheel dehumidification combined air conditioning system.

Authors: Liu Yuxi , Li Aihua , Lin Xuedong 
Published: June 2020

Abstract
Based on the macro-microscopic analysis of the fracture path of cortical bone, it is shown that the crack path of the cortical bone deflected obviously during bending fracture, which indicates that the microstructure of the cortical bone affects the crack propagation of the bone. According to the microstructure of cortical bone, a staggered structure analysis model of hydroxyapatite (HA) sheets was established, and the effects of the structural parameters and volume content of hydroxyapatite sheets on the crack deflection coefficient and fracture toughness were compared and analyzed. The analysis results show that the structural parameters and volume fraction of hydroxyapatite sheets are positively correlated with the fracture toughness of bone. When the bone is fractured, the cracks deflected between the staggered hydroxyapatite layers to dissipate more energy, thereby improving the fracture toughness of the bone. The research results can provide useful guidance for the design and manufacture of high-performance bionic bone composites.

Published: June 2020

Abstract
The steady-state steering characteristics of a vehicle directly affect its work efficiency and safety. The traditionalsteering mechanical modelof the wheeled vehicle does not take into consideration the influence of centrifugal force. Thus, in order to accurately calculate the various steering performance parameters during the actual steering of the vehicle, a mathematical model for steering of a wheeled vehicle is established based on an in-depth study of the wheeled vehicle steering mechanism, in which theinfluencing factors are taken into account, such as centrifugal force and tire slip/slip. Meanwhile, the specific vehicle model is used as an example to solve the numerical model. The results show that the centrifugal force generated during the steering of the vehicle will affect its steering performance. With change of the steering radius and vehicle speed, the slip radius and the amount of steering centerline movement increase or decrease accordingly, which affect the steering stability of the vehicle.
