As a large amount of data is increasingly generated from edge devices,such as smart homes,mobile phones,and wearable devices,it becomes crucial for many applications to deploy machine learning modes across edge devices.The execution speed of the deployed model is a key element to ensure service quality.Considering a highly heterogeneous edge deployment scenario,deep learning compiling is a novel approach that aims to solve this problem.It defines models using certain DSLs and generates efficient code implementations on different hardware devices.However,there are still two aspects that are not yet thoroughly investigated yet.The first is the optimization of memory-intensive operations,and the second problem is the heterogeneity of the deployment target.To that end,in this work,we propose a system solution that optimizes memory-intensive operation,optimizes the subgraph distribution,and enables the compiling and deployment of DNN models on multiple targets.The evaluation results show the performance of our proposed system.

Thermal conductivity silicone gel with low permeability and high filling was prepared by 200 mPa·s (PDMS-Vi200) and 500 mPa·s (PDMS-Vi500) as silicone oil, 0.05 wt% hydrogen silicone oil (PDMS-H) as cross-linking agent, and 5 µm (A0-05), 20 µm (A0-20) and 40 µm (A0-40) spherical A12O3 added with different ratios as heat conduction filler. The effects of spherical A12O3 and viscosity of PDMS-Vi on viscosity of adhesive and the maximum filling were studied. The effects of γ-mercaptotrimethoxysilane (KH590) on the thermal conductivity of silicone gel, as well as viscosity of PDMS-Vi, ratios of Si-H to Si-Vi and filling amount on the hardness, density, thermal conductivity and mechanical strength of silicone gel. The influence of the type and proportion of aluminua complex ligand on the anti oil permeability and heat resistance of silicone gel was studied. The results show that the thermal conductive silicone gel has been prepared by vinyl-terminated silicone oil, 0.05 wt% hydrogen silicone oil as the crosslinking agent, and spherical A12O3 with different particle sizes as filler. U-sing silicone oil with different viscosity as the base oil, 0.05 wt% hydrogen silicone oil as the crosslinking agent, and spherical A1203 with different particle sizes as the composite thermal conductive filler, thermal conductive silicone gel with low permeability and high filling has been prepared. When using 20 µm spherical A12O3 with a uniform particle size, there is no obvious increase on viscosity of the gel and the maximum filling is up to 1500 phr. The appropriate amount of KH590 (2.00 wt%) effectively improves the thermal conductivity of the silicone gel. When PDMS-Vi200 is used as silicone oil, the ratio of Si-H to Si-Vi is 0.8:1, A0-20 is used as thermal conductivity filler (600 phr), silicone gel has better performance, with Shore 00 hardness of 67, density of 1.83 g/cm3, thermal conductivity of 3.69 W/(m·K) and tensile strength of 1.95 MPa. The thermal conductivity of thermal conductive silicone gel prepared with different particle sizes is higher than that with one particle size, and when the mass ratio of A0-20 to A0-05 is 2/1, the silicone gel has a better thermal conductivity of 4.7233 W/(m·K). Due to the surface silanization of spherical A12O3, winding of silicone oil and hydrogen bonding effects of sulfhydryl groups with residual double bonds, it can significantly improve the permeability and heat resistance of silicone gel. Moreover, the silicone gel prepared by A0-20 to A0-05(mass ratio of 2/1) has better anti oil permeability and heat resistance, the oil permeability ratio is 1.0476, 5 wt% weight loss temperature of 331 t and the residual mass fraction of 89.10% at 700 °C.

The fatigue crack initiation of the fuselage structure skin under the uniform supercharged cyclic load of 0 ～ 7. 8 Psi was experimentally studied by the self-made aircraft fuselage skin uniform supercharged fatigue simulation device. The location of the fatigue crack initiation of the fuselage structure skin and the sequence of fatigue crack initiation are studied by finite element analysis. The research showed that under the uniform supercharged fatigue load,fatigue crack initiation occurred on the left and right sides of the nail holes. The fatigue crack initiation sequence is mainly related to the maximum Von-Mises stress value at the initiation site,but also related to the tightness of the connection between the skin and the stringer.

A finite element model is established for the pre-stressed composite pyramidal lattice structures. The influences of prestress on the contact force, contact duration, structural deformation, energy absorption and impact damages are investigated. Before subjected to low-velocity impact,the composite pyramidal lattice structure is pre-strained by the static responses. The numerical results indicate that pre-stress has no significant influence on the peak contact load,contact duration and rate of total energy absorption,while it plays an important role on the deformation. When the impact velocity is constant,the maximum displacement of impact center increases with increasing the tensile pre-stresses,but the maximum deformation of the bottom facesheet and the truss cores incline to decrease when tensile pre-stresses increase,while the effects of tensile pre-stresses on the structural deformation are otherwise.

A semi-analytical solution theory is presented by combining the separable Hamilton canonical equation and finite element method. The problem of free-edge effect of orthotropic laminates is studied in symplectic system. First, the separable Hamilton canonical equations are established with modified Hellinger-Reissner variational principle. And the state equations are established with finite element method. Then, an example analysis of the distribution of interlaminar stresses in composite laminates is calculated. The numerical results show the efficiency of the proposed method.

Aerated subsurface drip irrigation (ASDI) refers to the irrigation with aerated water based on Venturi principle by the use of subsurface drip irrigation (SDI) system. ASDI provides a source of oxygen to root environment that may suffer from temporary hypoxia, and therefore unlocks yield potentials of crops. But the efficiency of ASDI is dependent on a number of factors. Among which, proper operating pressure and surfactant concentration are of great significance for aeration efficiency and the uniformity of air and water flow in the aerated irrigation water stream. Proper control of air-water transmission will offer the industry an opportunity to further optimize the use of ASDI system and improve water use efficiency and minimize the environmental impacts of irrigation. The primary objective of this study was, therefore, to explore optimum working pressure and a surfactant sodium dodecyl sulfate - SDS addition on the flow uniformity of water-air irrigation in the drip pipeline. Nine combination were tested (3 working pressure at 0.05, 0.10, 0.15 MPa and 3 concentration level of SDS of 0, 5, and 16 mg/L, respectively). Each combination has aeration treatment and non-aeration treatment. Results showed that the aerated concentration was increased with increasing operating pressure even without surfactant addition. However, aerated concentration decreased with increasing operating pressure under surfactant addition. Under the same operating pressure, the aerated concentration increased with increasing surfactant concentration. The addition of surfactant significantly increased the equilibrium concentration in aeration treatment. The average value of water flow uniformity under aerated drip irrigation was greater than 95%, suggesting that there was no negative impact of surfactant addition on the water flow during oxygation. And the air flow uniformity of each combination remained above 70%. The oxygen transmission efficiency was improved with the addition of SDS. The surfactant concentration had a positive effect on the oxygen mass transfer coefficient, while the operating pressure had a negative effect on the oxygen mass transfer coefficient. The surfactant addition has greatly shortened the aeration time. The deviation between the observed and calculated aerated concentration were less than 5%, indicating that the calculation method was reliable for the aerated irrigation water stream. The operating pressure at 0.1 MPa and surfactant concentration of 5 mg/L was optimal combination. This research demonstrates great importance of the improvement of aeration efficiency and the air-water transfer for oxygation that can significantly reduce the cost of operation.

Early state formation has at least two common preconditions: massive productive economy, and the unequal society. The early Japanese state was such a political system, in which power maintained privileged access to basic resources. This state differed greatly in its means of exerting authority from primitive society, yet the clan system continued to function for an extended period. The character of the ancient Japanese state can be summarized in this way: the ancient Japanese state emerged independently in the Japanese islands due to their unique geographical situation, neither emerging from nomadic conquest nor departing from an existing state. However, in the development of the ancient Japanese state, external influences, especially that of China played a significant role. Specifically, external influences were felt in the realms of both political structures and cultural interaction. The so-called "privilege of historical trial" applied to the formation of the ancient Japanese state, as Japan, in a relatively short time, absorbed advanced cultural elements from the Chinese mainland and the Korean peninsula to drive forward the process of its state formation.

Objective: To identify the type and origin of ATP7B gene mutation in a family affected with Wilson disease by combined use of multiple methods., Methods: Peripheral blood samples were collected from the proband, her parents and her brother. Sanger sequencing were used to detect point mutation and small deletion/insertion of the 21 exons and flanking sequences of the ATP7B gene in all family members. Array-based comparative genomic hybridization (aCGH) was performed to identify copy number variations (CNVs) of the ATP7B gene in the proband. The result was validated by quantitative PCR (qPCR) in other 3 members., Results: Sanger sequencing indicated that the proband carried a heterozygous variation c.2668G>A (p.V890M) derived from her mother. In addition, 5 common SNPs were detected in her mother, three of which were also identified in her father and brother. The 5 SNPs in the proband were of the wide type. aCGH analysis demonstrated that the proband was heterozygous for a 4 kb deletion, which encompassed exons 2 and 3 of the ATP7B gene and 2 SNPs. qPCR showed that the copy number in her father and brother was about half of the control, indicating heterozygous loss of exons 2 and 3., Conclusion: The combined Sanger sequencing, array CGH and qPCR has identified a novel CNV involving the ATP7B gene. The strategy can improve the diagnostic rate for hereditary or rare diseases.
