- Abstract
The environmental challenges caused by hexavalent chromium [Cr(VI)] cannot be ignored. Here, a novel oxidized PASS (OPASS)/UiO-66-NH2nanofibrous membrane (OPASS/U NM) was successfully fabricated by electrospinning and an in situ growth process and applied for the removal of Cr(VI). It is found that the OPASS/U NM exhibits high adsorption performance due to its large surface area. Meanwhile, UiO-66-NH2particles are seamlessly and uniformly embedded on the surface of the OPASS fiber, which would endow the OPASS/U NM with photocatalysis reduction performance. Thus, under visible light, the OPASS/U NM could rapidly absorb Cr(VI) and reduce it to Cr(III), and the maximum removal capacity at pH 3.0 reached 20.10 mg/g. Furthermore, a possible photocatalytic reaction mechanism for removal of Cr(VI) is proposed. The OPASS/U NM also exhibits good stability, outstanding solvent resistance, and excellent recyclability. It retains a 92% reduction efficiency even after three cycles and shows a high recovery rate (>95%). More importantly, it can endure a series of strong polar solvents such as dimethylacetamide, N-methylpyrrolidone, and N,N-dimethylformamide. This research not only offers a strategy for enhancing the removal of Cr(VI) but also introduces a composite membrane suitable for wastewater containing aggressive solvents.

- Abstract
Our previous study showed that light-emitting diode modulation of the hypothalamic paraventricular nucleus (PVN), which is the control center of the sympathetic nervous system, might attenuate neuroinflammation in the PVN and prevent ventricular arrhythmias (VAs) after myocardial infarction (MI). Low-intensity focused ultrasound (LIFU) has deeper penetration than does light-emitting diode, while its effect on the PVN has not been reported. This study aimed to explore the effect of LIFU modulation of the PVN on the inducibility of post-MI VAs. Fifty-four Sprague-Dawley rats were randomly divided into acute control (n = 12, 22.22%), acute MI (AMI, n = 12, 22.22%), AMI + LIFU (n = 12, 22.22%), chronic control (n = 6, 11.11%), chronic MI (CMI, n = 6, 11.11%), and CMI + LIFU (n = 6, 11.11%) groups. MI was induced by left anterior artery ligation, and electrocardiographic recording for 0.5 hours after MI and programmed electrophysiological stimulation were used to test the vulnerability of VAs. Peripheral sympathetic neural activity was assessed by measuring left stellate ganglion neural activity. Finally, hearts and brains were extracted for Western blotting and histopathological analysis, respectively. Compared with the AMI group, AMI-induced VAs (P <.05) and left stellate ganglion neural activity (P <.05) were significantly attenuated in the AMI + LIFU group. In addition, LIFU resulted in a significant reduction of microglial activation in the PVN and expression of inflammatory cytokines in the peri-ischemic myocardium. In the CMI + LIFU group, there was no obvious tissue damage in the brain. LIFU modulation of the PVN may prevent the incidence of post-MI VAs by attenuating MI-induced sympathetic neural activation and inflammatory response. [Display omitted] [ABSTRACT FROM AUTHOR]

The existence of time delay in complex industrial processes or dynamical systems is a common phenomenon and is a difficult problem to deal with in industrial control systems, as well as in the textile field. Accurate identification of the time delay can greatly improve the efficiency of the design of industrial process control systems. The time delay identification methods based on mathematical modeling require prior knowledge of the structural information of the model, especially for nonlinear systems. The neural network-based identification method can predict the time delay of the system, but cannot accurately obtain the specific parameters of the time delay. Benefit from the interpretability of machine learning, a novel method for delay identification based on an interpretable regression decision tree is proposed. Utilizing the self-explanatory analysis of the decision tree model, the parameters with the highest feature importance are obtained to identify the time delay of the system. Excellent results are gained by the simulation data of linear and nonlinear control systems, and the time delay of the systems can be accurately identified. [ABSTRACT FROM AUTHOR]

Su, Yinxin, Wu, Yuzhe, Choguill, Charles L., Luo, Jiaojiao, and Yu, Xiaofen
- Abstract
Transit-oriented development (TOD) is a sustainable land use planning tool based on land value-added capturing and urban quality improvements and has been vigorously promoted by Chinese city governments. However, few studies have been conducted on the role of the ‘land finance’ model and on people-oriented planning approach focusing on urban inclusive growth. This paper examines the current implementation of TOD in China and attempts to explore the approach to the paradigm transformation of urban development in China. Evidence from Hangzhou illustrates that the current land-centered and property-led urban rail transit construction, although contributing to the economic sustainability of ‘urban development strategy’, has led to unaffordable housing prices and failed to decentralize population away from downtown areas. This study highlights inclusive growth models which integrate TOD planning with affordable housing for the floating population, not only to ensure equity in housing affordability and space accessibility but also to promote polycentric urban development strategies. The locations of inclusive growth models include new towns/sub-cities, traditional cores and suburbs, which are all based on existing industrial cluster areas and promote the full utilization of existing public service facilities.

NATIONALIZATION of land ,URBANIZATION ,URBAN homesteading ,RURAL land use ,PRIVATIZATION - Abstract
The rural collective land system plays an important role in urbanization; however, it hinders the capitalization of rural homesteads. Despite the significance of this system, the existing literature mainly focused on debates on privatization and nationalization of rural homesteads. However, only a few studies have proposed feasible plans for capitalizing fixed assets. To fill this research gap, this study discusses the conflict between market demand and legal limitation of the marketization of rural homesteads. The weaknesses and strengths of radical nationalization and privatization are also comprehensively evaluated. The concept of market-driven nationalization is proposed to overcome the weakness of radical nationalization and privatization while maintaining their strengths as much as possible. Finally, an assessment of the proposed market-driven nationalization is conducted based on an institutional analysis and development (IAD) framework. The key contribution of this study is its investigation into whether radically changing the rural collective land system is appropriate in contemporary China. In addition, this study proposes a potentially feasible path for advancing the capitalization of rural homesteads. [ABSTRACT FROM AUTHOR]

URBANIZATION ,LAND use ,GOVERNMENT policy ,LAND economics ,SUSTAINABILITY - Abstract
Since early 2016, the expiration of a part of the land-use rights in China has elicited widespread public concern because of the ambiguous interpretation of relevant legal clauses. Land-finance-based urbanization is the primary fiscal source of Chinese local governments, but it has been considered unsustainable by many scholars. Numerous studies have been conducted on these two issues, but a comprehensive study that combines both issues is needed. This study attempts to analyze the relations between the two concepts from the perspective of demographic change in the following decades. It proposes a compensatory mechanism based on land-use term and property tax to deal with the renewal of land-use term and the unsustainability caused by land finance. Results provide an alternative approach for the local government to realize sustainable urbanization in the future. [ABSTRACT FROM AUTHOR]

The planned economy system’s previous form of industrial land market control in China has led to current market failure because of a large amount of industrial land being sold at a very low price, causing extensive overuse of land and negative effects on land management. As the “World Factory”, the Pearl River Delta (PRD) is well known for its rapid urbanization largely driven by Foreign Direct Investment in labor-intensive industries. A low-land price strategy has been commonly adopted by the local government in order to attract industrial investment. In the past decade, the PRD has increasingly faced the increasing competition from its neighboring competition from its neighboring countries in Southeast Asia that have established preference policies to attract FDI and foreign enterprises. Despite a growing body of literature on the internal forces of industrial land in China, little is known of the external forces involved except for the importance of FDI and the intensity of interregional competition between China and other countries in attempting to attract foreign investment. This research fills the knowledge gap by modeling the situation in the form of an international cooperative game model aimed at revealing the industrial land price formation mechanism between the PRD region and Southeast Asian regions. The conditions of industrial land in the area and several Southeast Asian countries are first analyzed for their industrial land price movements in recent years. A game theoretic model is then built that exhibits similar characteristics. The result indicates that the governments’ low land price strategy and the competition between the PRD and its neighboring countries have created unnecessarily high social and environmental costs. Policy suggestions are made to encourage a more appropriate use of industrial land in China, and the most important being the need for a mindset shift from competition towards coopetition between the PRD and Southeast Asian regions.

HIGH resolution imaging ,DEEP learning - Abstract
Recently, the feature map recalibration (FMR) mechanism has been widely explored in single image super-resolution (SISR) and obtained remarkable performances. However, the existing FMR-based SISR methods directly incorporate the attention module into a deeper network structure (e.g. EDSR), while neglecting the differences between the low-level and high-level vision problems. In this paper, we design a low-level specific FMR mechanism for SISR task based on a new observation by examining current SISR methods, which all demonstrate a solid correlation between the SISR performance and the convolutional feature noise. Inspired by this, we extend the classic soft thresholding technique in the way of deep network, and develop an Adaptive Soft Thresholding (AST) module for feature noise suppression. Comparing to existing attention modules, AST is light-weighted and can be taken as an easy plug-in module in any SISR networks. To this end, we construct a adaptive Feature Denoising Super-Resolution (FDSR) network by combining the baseline EDSR and the proposed AST. Extensive experimental results show that the proposed FDSR network could achieve the state-of-the-art performances on SISR benchmarks, and significantly reduce the parameter (28.8% for EDSR, 74.6% for RCAN,s 76.0% for SAN) with respect to FMR module. • We propose a novel lightweight adaptive soft thresholding (AST) mechanism to perform the specific feature recalibration (FMR) for single image super-resolution (SISR). • We propose an adaptive Feature Denoising Super-Resolution (FDSR) network by embedding the proposed AST modules into the classic EDSR architecture.

- Abstract
Photodynamic therapy (PDT) is a palliative technique that can improve median survival with minimal invasion for cholangiocarcinoma (CC) patients. An ideal photosensitizer (PS) is critical to guarantee the efficacy of PDT. However, conventional PSs have some obvious drawbacks, such as lack of specificity and easy aggregation in aqueous media that limit their further application in the clinic. We herein fully take advantage of a red emissive aggregation-induced emission (AIE) PS to fabricate integrin ανβ3targeted organic AIE dots for image-guided PDT viaa simple and straightforward one-step strategy. The obtained AIE dots exhibit high specificity to CC as well as excellent antitumor effect both in vitroand in vivo. Different from conventional PSs and previously reported PS-loaded nanostructures, the AIE dots do not suffer from aggregation-caused fluorescence quenching and reduction in reactive oxygen species production when the AIE PS molecules are in an aggregated state. The significant antitumor effect, as well as good biocompatibility and negligible toxicity, makes the AIE dots promising for future translational research in CC diagnosis and therapy.

- Abstract
Industrial air pollutants have serious harmful effects on human health, as industry exhaust is among the main sources of air pollutants, particularly in developing countries. Thus, in this work, a novel material, oxidized poly(arylene sulfide sulfone)/UiO-66-NH2(OPASS/UiO-66-NH2) nanofibrous membrane, was developed for the removal of both volatile organic compounds (VOCs) and PM2.5via electrospinning, post-oxidation treatment, and in situ vertical growth. The result of scanning electron microscopy, Fourier transform infrared, X-ray diffraction, and X-ray photoelectron spectroscopy demonstrated that the OPASS/UiO-66-NH2nanofibrous membrane was successfully prepared. In addition, four kinds of OPASS/UiO-66-NH2nanofibrous membranes were systematically investigated to obtain the optimum one, which was treated for 15 min for UiO-66-NH2growth. It is found OPASS/UiO-66-NH2nanofibrous membrane has outstanding comprehensive performance, high filtration efficiency (99.98%), low pressure drop (120 Pa) for PM2.5removal, and high sorption capacity (30.3, 28.7, and 20.3 mg/g) to dichloromethane, toluene, and benzene. More importantly, the OPASS/UiO-66-NH2nanofibrous membrane could endure high temperatures (250 °C) and harsh environments (N-methylpyrrolidone) and still retain a stable morphology and excellent removal performance for PM2.5and VOCs. The outstanding performance of OPASS/UiO-66-NH2nanofibrous membrane shows potential for the application in high-temperature flue gas treatment.

The Land Administration Domain Model (LADM), an international standard (ISO 19152:2012), provides a conceptual data model for land administration. This study applies the LADM model to a previously unexplored case: the administration of homestead lands (residential lands) in rural China. In China, rural homestead tenures have been altered through several iterations since 1949, variously serving economic development, political governance and social security objectives. An intended contemporary reform of the homestead tenure system is based upon: (1) collective ownership by local communities; (2) qualification rights, a kind of personal servitude to safeguard the social security of individual community members; and (3) use rights, usufructuary interests offering management options to promote economic development. This work shows it is possible to translate this tripartite entitlement reform of rural homesteads into an LADM profile, with rights, persons, and land forming the base components. Four (sub) packages are formed, namely, Party, Administrative, Spatial Unit and Surveying and Representation. The work finds the LADM-based model, applied to the administration of China's rural homesteads, could facilitate the land tenure reform of rural homesteads, enable interoperability with other aspects of land administration, and could support national responses to those Sustainable Development Goals (SDGs) relating to poverty eradication, rural revitalization and intensive land use. • The evolution of rural homestead property system since the foundation of People's Republic of China is summarized. • The existing rural homestead rights structure after the tripartite entitlement reform is discussed. • An LADM-based rural homestead administration system for facilitating land tenure reform is developed.

- Abstract
The introduction of comprehensive zone price of land requisition may raise the standards {or land requisition compensation and provide a powerful policy security for the interests of rural collectives. However, as the measure is still based on the agricultural land, it can't guarantee the living standard and basically solve the problem of land-lost farmers. The problem is that land-lost farmers can't share the land development rights from the land use conversion. So the distribution proportion of land development rights revenue is put up, according to the usual distribution of revenue in the allotted land circulation. The state gets 60%, and the rural collective gets 40%. With joint investment, a social security system is set up for land-lost farmers to leave their worries behind. After this, the measure of comprehensive zone price of land requisition is improved to exemplify the land development rights. The total revenue of land development rights is acquired by subtracting agricultural land use earnings and general land development costs from urban land granting fees. Through an investigation of the farmers' wishes, the shared proportion of land development rights for rural collectives may be acquired, with which the specific share for rural collectives is acquired logically. Finally, comprehensive zone price of land requisition is acquired by adding shared land development rights revenue and agricultural land use earnings. [ABSTRACT FROM AUTHOR]

Land use planning has become an important topic for research in China and a critical public management means to restrain and regulate land use behavior. China's current land use planning can be divided into different levels of planning, that is, national planning and local planning. The central government designs land use planning that emphasizes control and longer-term goals; whilst local governments tend to have shorter planning time scales and more market-oriented goals. This government-led type of planning system often caused mismatches between supply and demand and planning failures. This is a challenge facing researchers and policy makers in China at all levels. In this paper we propose the use of nudges as a new approach of government interventions to tackle this problem. We develop a theoretical framework to embed nudges in land use planning, and use Zhejiang Province as a case study to demonstrate the empirical implementation of the framework. We argue that nudge-based government interventions are efficient and effective alternatives for conventional, direct administrative orders. It facilitates decisions that can both improve private welfare and protect public interests; it strikes a balance between government interventions and market forces while still preserves the freedom of choices. It is a promising direction for the research and practice of land use policy in China and beyond. • Land use planning that emphasizes rigid control is difficult to adapt to the market demand for land. • Nudge has become a new method of public management reform. • The paper proposes a theoretical framework embedded with nudges. • The framework combines government interventions and market forces effectively. • The aim is to promote the balance between long-term planning and short-term planning.

20. A study on promoting the intensive use of industrial land in China through governance: A game theoretical approach

- Abstract
Extensive use of industrial land has been typical for many cities in China since the end of the previous century. One of the most important reasons is the local governments’ strategy choice in land use. In this research, a governance structure from the view of the tax-sharing system and the performance appraisal system is constructed to explain the causes of extensive land use using game theory analysis. The key finding is that the governance structure in industrial land use is an organizational structure composed of the central government, local government and the market, and these three participants hold inter-conditioned relationships so as to form a closed loop. However, a bottom-up relationship chain from the market is absent in this structure, which makes it difficult to rely on local governments to implement intensive use of industrial land by themselves. Game equilibrium analysis shows that if a performance penalty coefficient is considered to refine the existing performance appraisal system to help produce a market feedback, the possibility of local governments adopting extensive land use strategies will be reduced.

Due to the negative image of public housing projects, housing policies globally tend to shift from government-led to market-led, from project-based subsidies to household-based subsidies. What theories does the Chinese government rely on to launch a large number of public housing construction projects since the beginning of 21th Century? In the past decades, what kind of impact has the supply of public housing produced on urban development? From the perspective of urban inclusive growth, a discussion on the impact of public housing supply policy is not sufficient to fully analyze this diversity. Therefore, this paper includes theoretical and empirical research to explore the association between the supply of public housing and urban inclusive growth in China. A data-driven method is adopted that provides analysis of China's socio-economic situation. Based on nationwide observations, the structural equation model is applied in testing the impact of public housing supply on urban inclusive growth. The results run counter to the stereotype and indicate that, at this stage, increasing the supply of public housing not only contributes to urban social integration, but also does not hinder urban economic growth. This study shares the Chinese experience of the impact of public housing supply on urban inclusive growth, and provides support for the urban development model based on inclusive growth theory. • An empirical study is conducted from both the economic growth and social integration perspectives. • Increasing the supply of public housing does not hinder urban economic growth. • The quantity of public housing supply has the greatest impact on urban inclusive growth. • Provides support for the urban development model based on inclusive growth theory.

• This paper reviews the history of indemnificatory housing development and explores its effectiveness. • An optimization-based framework for housing subsidy system that focusing on housing voucher is designed. • We provide an effective alternative housing subsidy policy which can facilitate the settling down of migrants in cities. • Capitation grant, occasion for implementation and cost estimation are important elements in housing subsidy system. Rapid urbanization has transformed cities by improving the quality and quantity of production factors, such as population, land, and capital gain optimization. However, housing problems of the floating population (liudong renkou) have seriously increased during the urbanization process. This study reviews the history of indemnificatory housing development in China and explore its effectiveness in the context of sustainable urbanization. Difficulties in the housing subsidy policy are identified, and an optimization-based framework for housing subsidy system that focusing on housing voucher is designed with the consideration of capitation grant, occasion for implementation, cost estimation, implementation procedure, and supplementary policy. The appropriateness of the housing voucher policy was tested on Zhejiang Province, and expert interview was conducted to evaluate the proposed housing subsidy system. This study provides an effective alternative housing subsidy policy which can facilitate the settling down of floating population in cities and also contribute to sustainable urbanization.

• The evolution process of farmland right system since the foundation of new China is summarized. • The existing farmland right system after the tripartite entitlement reform is proposed. • An LADM-based farmland administration system is developed. • Some instance level diagrams for farmland administration activities is developed. Since the beginning of the 21st century, China has undergone a promotion of industrialisation, urbanisation and agricultural modernisation. This promotion has triggered the mass migration of rural labour forces into cities, leading to the virtual situation of the separation of farmland contract and operation rights. To respond to this issue, the central government proposed a strategy of farmland reform in China. Such reform aims to transform the former 'Bipartite Entitlement System' into a 'Tripartite Entitlement System (TES)'.
1 1 'Bipartite Entitlement System' refers to the separation of farmland contractual operation right and farmland ownership. 'Tripartite Entitlement System' is the second separation of farmland contractual operation rights, which is transformed into the contract and operation rights. Thus, the 'Tripartite Entitlement System' is composed of three individual farmland rights: ownership, contract right and operation right. Land registration provides the means for recognising formalised property rights and regulating the characteristics and transfer of land-related rights. As for farmland registration in China, it serves as a basis to explore effective forms of collective farmland ownership by implementing collective farmland ownership, stabilising farmers' contract rights and liberalising farmland operation rights. Thus, in this study, on the basis of the farmland tripartite entitlement (hereinafter referred to as 'FTE') reform in China, we develop a Land Administration Domain Model (LADM)-based TES model that will serve as the basis of subsequent system development. Specifically, first, we summarise the evolution process of China's farmland rights system since the foundation of new China. Second, we propose a farmland rights system after the FTE reform. Then, the corresponding TES model is developed based on the LADM standard and some instance-level diagrams for farmland administration activities. The new functionality of the model includes improved structuring of farmland rights and restrictions (and related source documents) and improved expansion of the land information infrastructure to rural areas.

Wu, Yuzhe
- Abstract
Edge is one of the most important features of an image because it recognizes the world through images and understands the position and contour of objects in images through edges. Edge monitoring of depth image is the basis of object recognition and location. The contour curve calculates the feature points and maps them to the original contour space. The original contour is matched by a sequence of markers. At the initial stage of recognition, the dissimilar targets and different gestures are eliminated quickly. The candidate list of targets is generated for accurate matching to improve the recognition efficiency. The curve is a nonlinear extension of the first principal component, emphasizing the search for the "middle" through the distribution of data, starting from an arbitrary point of the image, estimating the pixel points near the point and obtaining the gradient value. If the point satisfies the characteristics of the edge point, then the point detour depth traverses to find edge points that are perpendicular to the direction of the gradient and marks the visited points. And satisfy the self-consistent smooth curve without parameters, these curves give an overview of the data. Determine the degree of approximation; when the judgment has converged to the target contour, continue to converge and penetrate the concave area of the target contour.
