Existing machine learning potentials for predicting phonon properties of crystals are typically limited on a material-to-materialbasis, primarily due to the exponential scaling of model complexity with the number of atomic species. We address this bottleneckwith the developed Elemental Spatial Density Neural Network Force Field, namely Elemental-SDNNFF. The effectiveness andprecision of our Elemental-SDNNFF approach are demonstrated on 11,866 full, half, and quaternary Heusler structures spanning 55elements in the periodic table by prediction of complete phonon properties. Self-improvement schemes including active learningand data augmentation techniques provide an abundant 9.4 million atomic data for training. Deep insight into predicted ultralowlattice thermal conductivity (<1 Wm^(−1) K^(−1)) of 774 Heusler structures is gained by p–d orbital hybridization analysis. Additionally, aclass of two-band charge-2 Weyl points, referred to as “double Weyl points”, are found in 68% and 87% of 1662 half and 1550quaternary Heuslers, respectively.

[Objectives] The research aimed to explore extraction method of Oenanthe benghalensis polysaccharide,and determine the optimal process of its ultrasonic extraction by orthogonal test. [Methods] Phenol-sulfuric acid method was used to determine polysaccharide's content. Based on single-factor experiment and orthogonal test,the influences of solid-liquid ratio( A),ultrasonic extraction temperature( B),ultrasonic power( C) and ultrasonic time( D) on extraction rate of O. benghalensis polysaccharide were studied,and the optimal process of ultrasonic extraction was selected. [Results] The influence order of solid-liquid ratio( A),ultrasonic extraction temperature( B),ultrasonic power( C) and ultrasonic time( D) on extraction rate of O. benghalensis polysaccharide was A > D > B > C. Via the orthogonal test,it was determined that the optimal extraction condition of O. benghalensis polysaccharide was as below: solid-liquid ratio 1∶ 25( g/mL),extraction temperature 60℃,extraction power 80 W,extraction time 40 min. Under the condition,extraction rate of O. benghalensis polysaccharide was9. 80%. [Conclusions] The process could provide the reference basis for extracting and producing O. benghalensis polysaccharides.

New concept of heat transfer enhancement by flow-induced vibration was put forward, and a novel heat transfer element called elastic tube bundles was designed. The experimental investigation was performed on its characteristics of flow-induced vibration in out-tube or in-tube flow. Under the conditions of fixed heat flux and steam-water heat transfer, the regularity of heat transfer enhancement by flow-induced vibration was examined.

目的本研究旨在了解本中心体外循环变温水箱是否有非结核分枝杆菌(NTM)污染。方法在含氯消毒剂消毒水箱后次日,留取本中心1号楼19个水箱的水样,进行NTM培养。对于水样分枝杆菌培养阳性的水箱,用无菌拭子分别涂抹水箱内胆生物膜和水箱出风口处,做NTM培养和鉴定,采用rpoβ基因和16S rRNA基因片段聚合酶链反应扩增测序,将测序结果进行基本局部比对搜索工具(BLAST)比对以确定菌种。结果4个水箱的水样检测NTM阳性,2个水箱在内胆和出风口都检测到奇美拉分枝杆菌,1个水箱仅在内胆区检测到奇美拉分枝杆菌,1个水箱在内胆区和出风口分别检测到戈登分支杆菌和奇美拉分枝杆菌。结论本中心体外循环变温水箱存在NTM污染,以奇美拉分枝杆菌为主。应通过加强变温水箱NTM监测、使用过滤水、定期清除生物膜、定期消毒、合理摆放水箱等方法降低NTM污染和感染风险。

Bone defects caused by trauma, infection or bone tumor resection, are highly prevalent. A small number(5%–10%) of these injuries fail to heal due to non-union and require surgical intervention. Currently, the principal treatment options for these defects are autografts, allografts, xenografts or synthetic grafts. The main problems associated with these therapies include pain,infection and donor site morbidity. Bone tissue engineering is a diverse field that focuses on the regeneration of bone by combining cells, scaffolds, growth factors and dynamic forces. There have been many recent studies utilizing biomineralized polymer matrix composites which mimic the natural structure of bone. The principal focus of this review is on recent advances in the synthesis of various types of biomineralized polymer matrix composite. Examples of the biomineralization of naturallyderived and synthetic polymers widely used for bone engineering are also summarized.

We study the problem of defense strategy against Objective function attack(OFA) in Cognitive networks(CNs), where the network can be operated at the optimal state by adapting the parameters of its objective function. An OFA attacker can disrupt the parameter adaptation by interfering measures, which results in some operating parameters of the objective function deviating from their optimal settings. We first model the interactive process between the OFA attacker and defense system using differential game theory, and propose a defense strategy by introducing a new metric, namely, threat factor. Then,we obtain the optimal defense strategy by proving the existence of the saddle point of the proposed model. Moreover,this defense strategy is scale-free such that it can conquer a large number of OFAs in a decentralized way. Finally, we conduct extensive simulations to show that the proposed approach is effective.
