Wangjiawan Gold Deposit is located in the southern part of the Jiangnan orogenic belt of the Yangtze continental block, on the southeast margin of the Li Liu uplift belt, in the north segment of the Nanyuanchong complex fold, which is in the northeast Hunan sub-segment of the Hunan segment of the Qinhang metallogenic belt. It is situated in the southern part of the Liuyang - Banshanpu exploration target area for gold, copper, lead, and zinc mineralization. The ore bodies mainly occur in the Lengjiaxi Group strata, with cleaved zones serving as ore-conducting and ore-controlling structures in the mining area, most of which are controlled by NW-trending cleaved zones. The ore types are predominantly primary ores, with an industrial type characterized by fractured altered rock with quartz veinlets. The hydrothermal mineralization of the deposit can be divided into 4 stages, with the quartz pyrite arsenopyrite gold stage and the quartz carbonate polymetallic sulfide - silver gold stage being the main mineralization stages. Silicification, pyritization, and arsenopyritization are closely related to gold mineralization. Wangjiawan Gold Deposit is a mesothermal vein-type gold deposit dominated by metamorphic hydrothermal fluids. [ABSTRACT FROM AUTHOR]

SnTe has been widely studied as an alternative to PbTe because of its similar crystal structure and band structure to PbTe, the thermoelectric material with the best performance in the middle temperature region. Reducing the energy difference between heavy and valence bands and enlarging the band gap of SnTe are effective means to optimize the thermoelectric performance of SnTe. In this paper, by co-doping SnTe with Bi and Ag, the energy difference between heavy and valence bands is effectively reduced, the band gap is obviously increased, and the Sn1 -2x Bix Agx Te(x = 0,0. 01,0. 02,0. 03,0. 04) samples with improved electric transport properties are obtained. Compared with undoped SnTe, the power factor of Sn1 -2x Bix Agx Te samples doped x =0. 03 and 0. 04 is significantly improved, and the maximum power factor of Sn0. 94 Bi0. 03 Ag0. 03 Te samples is 15. 34 μW·cm-1 ·K-2, which is 12. 9% higher than undoped SnTe. The maximum power factor of Sn0. 92 Bi0. 04 Ag0. 04 Te sample is 14. 53 μW·cm-1 ·K-2. At the same time, Bi and Ag doping decreased the thermal conductivity of SnTe. In this study, the total thermal conductivity of Sn0. 92 Bi0. 04 Ag0. 04 Te samples is significantly lower than that of undoped SnTe, and the thermal conductivity of all samples gradually decreases with the increase of temperature. At 823 K, the total thermal conductivity of Sn0. 92 Bi0. 04 Ag0. 04 Te sample decreases to 3. 073 W·m-1 ·K-1, and its ZT value increases to 0. 387. It can be seen that the co-doping of Bi and Ag is an effective strategy to improve the thermoelectric performance of SnTe. [ABSTRACT FROM AUTHOR]

In the existing mobile crowd sensing, most studies treat each task as an independent individual, and lack of research on the constraint relationship between tasks. For example, the task of urban environmental continuous monitoring need rely on historical tasks to complete current tasks. In view of this, this paper proposed a Online Task Collaboration Method Based on Sensing Quality Priority（TCSP）. Firstly, this method used greedy algorithm to calculate the sensing quality priority, screened all tasks to ensure the task completion rate. Then this method constructed a task cooperation graph for multiple subtasks that have time sequence or execution logic relationship in the selected task and modelled cooperation process as a constrained Markov decision process, obtained the optimal cooperation strategy through reinforcement learning algorithm. Experimental results verify that compared with the existing baseline methods, the proposed task collaboration method can reduce the average completion time of dependent tasks and reduce the average sensing cost of the platform.

Cangshan Gold Deposit is located in the middle part of the EW tectonic belt in northwest Hunan and the EW Yuanling - Yiyang ore-forming belt of Au, Sb and W. The geological characteristics of the Cangshan Gold Deposit are studied by means of simple geological survey, engineering exposure and sample analysis. The results show that the interlayer fault of Madiyi Formation of Banxi Group is the main ore-bearing strata, and the 4 veins of V2, VI, V4 and Vl9 are parallel to the EW - NEE direction. The ore types are gold-bearing quartz vein type, gold-bearing quartz (broken) altered slate type and gold-bearing altered breccia type. Based on the comprehensive study of the metallogenic geological background, the geological characteristics of the mining area and the geological characteristics of the deposit, it is believed that the deposit type belongs to the medium-low temperature tectono-metamorphic hydrothermal type, and the fading, silicification and pyritization of the surrounding rock are important prospecting indicators.

In order to grasp the bearing capacity, the distribution and transfer law of the force of the cast-in-place pile, the static load test of the cast-in-place pile was carried out, the optic fiber sensor was used to monitor the deformation of the cast-in-place pile, the strain information of the pile was obtained. Using the finite element software ABAQUS, the numerical simulation study on the bearing characteristics of cast-in-place pile was carried out. The results show that the Q-S curve of the pile foundation obtained by the static load test is basically consistent with the Q-S curve of the pile foundation obtained by the numerical simulation. The results of optic fiber sensor show that the axial force of the pile is the largest at the pile head, and gradually decreases with the pile length increasing, the overall change law is consistent with the numerical simulation results. The variation law of measured shaft side friction cast-in-place pile along the pile length is basically consistent with the force distribution and transmission of pile obtained by numerical simulation, it verifies that the parameters selected in the finite element calculation model are reasonable. The influence of pile length, pile diameter and friction coefficient of pile-soil interface on Q-S curve of pile foundation, axial force distribution of pile shaft and lateral friction distribution are considered. The influence of pile diameter and friction coefficient of pile-soil interface on Q-S curve of pile foundation, the influence of pile diameter and friction coefficient of pile-soil interface is great, while the influence of pile length is small.
