Aiming at the problem of how edge computing and Content Delivery Network (CDN) edge nodes implementing the resource coordination, the technology and method of CDN cache software adapting to virtual machines and containers are proposed. By comparing and analyzing the performance test data of CDN in three deployment modes of physical machine, container and virtual machine, the performance loss caused by CDN virtualization is evaluated. The performance loss of the container mode is small, and its performance is comparable to the physical machine. The performance loss of the virtual machine mode is large, and its performance is equivalent to about 75%of the physical machine. According to the nominal value of performance, the virtualized CDN edge node can release most of the central processing unit, memory and disk resources, and achieve resource sharing with edge computing.

Vanadium–chromium-reducing residue (VCRR) was generated using a sodium-roasting-leaching-precipitation process for vanadium recovery. The retained vanadium and chromium could be utilized for an important sources. Here, a novel process was developed that utilized ultrasonic to enhance the alkaline leaching process of vanadium from VCRR. The effect of various parameters was studied, and a corresponding kinetic model was established. It was found that the maximum vanadium leaching efficiency of 96.9% was obtained at optimum reaction conditions: reaction temperature of 90°C, reaction time of 60 min, dosage of NaOH at m(NaOH)/m(VCRR) = 0.5 g/g, liquid-to-solid ratio of 5 mL/g, stirring rate of 500 rpm, and ultrasonic frequency of 40 kHz. The leaching kinetics analysis showed that the leaching process was controlled by diffusion through a product layer both in normal leaching and ultrasonic leaching. The calculated Ea for vanadium leaching out was 20.56 kJ · mol−1 for ultrasonic leaching and 23.06 kJ · mol−1 for normal leaching. Ultrasonic-assisted leaching might be a potential industrial application technique for recovery of valuable metals from metal ores. [ABSTRACT FROM AUTHOR]

Maoist policy in China emphasised the peasants and workers. It integrated academic study with productive labour to nurture socialist citizens useful for the nation's modernisation. More recently, China has been described as having a 'neoliberal turn' but many see the situation as more complex than this due to the significant role given to the state in economic development and governance. Using the film 'Breaking with Old Ideas' [Li, W. (1975). "Breaking with old ideas" [Motion picture]. China: Beijing Film Studio] to inform, and stimulate participants, this study examined how a group of 15 Chinese students at an Australian university perceived the transformation of higher education in China. Findings generated from written responses and interviews addressed the relationship between neoliberal imaginings and Foucauldian subjectification processes in post-Maoist China, supporting the thesis that China cannot be called neoliberal in the traditional sense of the word. In terms of education, there co-exist socialist and neoliberal rhetorics with tensions between Confucianism, suzhi (quality) and traditional examination-driven models.

Egao (spoofing), a popular form of Chinese parody, employs humorous and mocking techniques in verbal and visual forms. Its grassroots nature often endows egao with an anti-authoritarian stance, but little scholarly attention has been paid to the increasing use of egao by Chinese public officials on social media. This article looks at this new trend by examining how local officials on the Chinese version of TikTok, Douyin, use egao. Drawing on Bakhtin’s concept of carnivalesque, we employ Multimodal Critical Discourse Analysis to examine the online communication style of 54 official accounts on Douyin. We thereby highlight three key features of the dynamic and complex nature of power relations in contemporary political communication in China: how they represent ethnic minority cultures; how they use typical egao forms to parody rebellious characters and subvert traditional Confucian junzi images; and their use of ‘light’ egao to reconstruct ancient characters and heroic images through Gufeng and Wuxia genres. We argue that the power relations between officials and the grassroots are not subverted but rather disguised through a complex negotiation within the state’s promotion of cultural soft power, tourism, and economy, which is aligned with Xi Jinping’s political doctrine of ‘Telling the China Story Well’.

This paper argues that the proliferation of the new term 'baby man' has an impact on reconstructing established gender relationships and resisting China's authoritarian political power in a highly-censored online environment. This study employs feminist critical discourse analysis to investigate how Chinese feminism adopts the discursive construction of 'baby man' and how they echo the complex historical and sociocultural backgrounds through a case study of 43 posts containing 'baby man' on Chinese social media. The finding suggests that the term 'baby man' is employed in discursive strategies, namely, double irony, the blunt resistance against both gender and power relationships that deconstruct the heteropatriarchal gender norm through the mother – son female gaze and contempt for the nation's past and current population policy. It argues that despite perennial censorship, these three discursive strategies help reconstruct the extant gender hierarchy backed by conservative Confucianist ethics and represent a grassroots challenge to the political authoritarianism indoctrinated by the state.

Many hydro-metallurgical methods are developed to recover vanadium, while ammonium salt precipitation possesses the final step and it has threatened the environment. The key point is to find a new compound to replace ammonium salts without reducing vanadium recovery efficiency. Some compounds with –NH2 function groups have attracted our attention as they have similar function groups with ammonium salts. In this paper, the adsorption of vanadium with melamine is conducted. The results show that high adsorption efficiency can be achieved in a short time and melamine displays great performance in the recovery of all concentrations of vanadium. Response surface methodology (RSM) is used to optimize the reaction conditions and order the parameters: reaction temperature > concentration of vanadium > dosage of melamine > reaction time. 99.63% vanadium is adsorbed under optimized conditions: n(melamine)/n(V) = 0.6, reaction time of 60 min, 10 g/L vanadium solution and reaction temperature of 60°C. The successful application of melamine in the recovery of vanadium provides a new way for the utilization of melamine and also a glorious future for –NH2 compounds in the recovery heavy metals.

Microstructural evolution and mechanical property degradation of the newly developed G115 steel during thermal exposure are highly important for the safe power plant operation. In this paper, the microstructural stability and strength as well as impact toughness were investigated after aging at 650°C and 700°C up to 5000 h. It was found that when aged at 650°C in the G115 steel, the size of M23C6 carbides and the width of martensitic laths had little change even increasing aging time up to 5000 h. Both the room-temperature and high-temperature strengths remained stable after aging for 5000 h. In comparison, after aging at 700°C, high-density Laves phases precipitated accompanied by coarsening with increasing aging time. The majority of martensitic lath structure was replaced by sub-grains and the strength decreased linearly. Most importantly, the impact toughness of G115 steel aged at both 650°C and 700°C decreased sharply and embrittlement occurred rapidly in the initial aging period. The evidence provided by fracture morphologies proved that Laves phase was the culprit of decreasing the impact toughness.

B cells foster squamous cell carcinoma (SCC) development through deposition of immunoglobulin-containing immune complexes in premalignant tissue and Fcγ receptor-dependent activation of myeloid cells. Because human SCCs of the vulva and head and neck exhibited hallmarks of B cell infiltration, we examined B cell-deficient mice and found reduced support for SCC growth. Although ineffective as a single agent, treatment of mice bearing preexisting SCCs with B cell-depleting αCD20 monoclonal antibodies improved response to platinum- and Taxol-based chemotherapy. Improved chemoresponsiveness was dependent on altered chemokine expression by macrophages that promoted tumor infiltration of activated CD8(+) lymphocytes via CCR5-dependent mechanisms. These data reveal that B cells, and the downstream myeloid-based pathways they regulate, represent tractable targets for anticancer therapy in select tumors.
