The isoperimetric problem in the Riemannian manifold admitting a non-trivial conformal vector field
Full text linkIn this article, we will study the isoperimetric problem by introducing a
mean curvature type flow in the Riemannian manifold endowed with a non-trivial
conformal vector field. This flow preserves the volume of the bounded domain
enclosed by a star-shaped hypersurface and decreases the area of hypersurface
under certain conditions. We will prove the long time existence and convergence
of the flow. As a result, the isoperimetric inequality for such a domain is
established. Especially, we solve the isoperimetric problem for the star-shaped
hypersurfaces in the Riemannian manifold endowed with a closed, non-trivial
conformal vector field, a wide class of warped product spaces studied by Guan,
Li and Wang is included.Comment: 30 page
The renewal of hollow village A research and proposal of Erhai area in YunNan, China
No full textUnder the background of rapid urbanization in China, hollowing phenomenon happened in several villages accompanies with the population loss, vacant houses and land abandonment. The Development is later in southwest of China than in the central and eastern regions. Thus, the research on problems during urbanization process is not deep and also lack of research for hollow village. Currently, southwest is under rapid urbanization development stage and due to the unique geography and resource, the development of Erhai area is influenced by urbanization and tourism. This paper mainly studies the influence factors and phenomenon and makes appropriate renewal suggestions through investigation and analysis of the Erhai area. This study belongs to the whole village space research, involving both urban design and industrial development impact, emphasizing the systematic analysis. Focused on three issues: 1) how do spatial factors influence in the process of hollowing in Erhai villages? 2) what are the changes and problems that appeared in Erhai villages? 3) how to renew the hollow villages based on regional potential in Erhai area? This paper analyzes the spatial structure and factors in Erhai area from the perspective of urban planning. Through literature research on the concept, the classification and discussion the existing regulation mode of hollow village, I get a deeper understanding of the topic. Furthermore, spatial elements are used in analysis the case. Analysis contains two parts: the evolution of village spatial structure and the various changed elements within villages. Specifically, it analyzes the relationship between the spatial structure, evolution process and hollowing phenomenon. Then, more detailed analysis focuses on village changing in representative villages. It analyzes from the basic change in single building, building combinations and surrounding environment and tries to find problems. Finally, the author hopes to combine the development of tourism as well as the concept of city for people to look for the renewal method for the area. The first finding of this paper is the underlying different development background, the problem has different variations, with strong regionalism. Therefore, there can be no uniform renewal mode for all hollow villages. Appearing of hollow village is caused by missing or imbalance of certain elements during the development process in the region. In the Erhai area, the village seems more probably hollowing which developed earlier, with convenient traffic conditions and the developed in tertiary industry. However, serious problems actually have more direct link with the government behavior and blind development, lack of reasonable planning. Hollowing not only performs in material terms, but also in terms of the loss of the humanities. The existing renewal mode for such issues always neglected the part of cultural loss. The author believes it needs to consider more for people, combine with the results of theoretical and case studies, and make the final suggestions. Finally, this paper puts XiZhou village as an object, a reasonable planning as method, to create a better living environment for the people as the aim to improving the problem Hollow Village. The theoretical significance: the paper is to expand the research method to the problem of villages hollow in space aspect and to fill the research on southwest hollow village and provide support for local authorities making measurement of hollow village. The practical contribution of this paper is helpfully to solve the specific problems of hollow villages in Erhai area
Relationships between the gelatinization of starches and the textural properties of extruded texturized soybean protein-starch systems
Full text linkStarches from diverse sources have different thermal properties and, thus, show different gelatinization degrees under a specific extrusion condition, which affects the quality of the extrudates. To find the appropriate ingredients for extruding texturized soybean protein-starch mixtures, the thermal properties of commercial-grade starches (wheat starch, corn starch, potato starch, sweet potato starch, cassava starch, mung bean starch, pea starch, amylose from potato, and amylopectin from waxy corn), blends of starches with soybean protein isolate (SPI) and wheat gluten were assessed. The extrusion response parameters (torque, pressure change, specific mechanical energy (SME), and on-line apparent viscosity) during extrusion and the thermal and textural properties of the extrudates were determined. Pearson correlation analysis showed that the enthalpy changes of the blends were directly correlated with the torque, pressure change, specific mechanical energy, and on-line apparent viscosity, whereas those parameters were inversely correlated with the fibrous degree of the extrudates. The hardness, tensile strength, lengthwise strength, and fibrous degree of the extrudates were correlated with the enthalpy changes of the blends. The springiness and fibrous degree of the extrudates were correlated with the half-peak height of the blends. It was concluded that a higher enthalpy changes of blends leads to a higher SME and a pressure change, which results in a higher hardness and tensile strength and a lower fibrous degree of the extrudates.Fil: Zhang, Wei.

Efficient Intersystem Crossing in Tröger's Base Derived From 4‐Amino‐1,8‐Naphthalimide and Application as Potent PDT Reagent
Full text linkIntersystem crossing (ISC) was observed for naphthalimide (NI)-derived Troger's base, and the ISC was confirmed to occur by a spin-orbital charge-transfer (SOCT) mechanism. Conventional electron donor/acceptor dyads showing SOCT-ISC have semirigid linkers. In contrast, the linker between the two chromophores in Troger's base is rigid and torsion is completely inhibited, which is beneficial for efficient SOCT-ISC. Femtosecond transient absorption (TA) spectra demonstrated charge-separation and charge-recombination-induced ISC processes. Nanosecond TA spectroscopy confirmed the ISC, and the triplet state is long-lived (46 mu s, room temperature). The ISC quantum yield is dependent on solvent polarity (8-41 %). The triplet state was studied by pulsed-laser-excited time-resolved EPR spectroscopy, and both the NI-localized triplet state and triplet charge-transfer state were observed, which is in good agreement with the spin-density analysis. The Troger's base was confirmed to be a potent photodynamic therapy reagent with HeLa cells (EC50=5.0 nm)
Improving behavioral decision making in operations and food safety management
No full textThis electronic version was submitted by the student author. The certified thesis is available in the Institute Archives and Special Collections.Thesis: Ph. D., Massachusetts Institute of Technology, Sloan School of Management, Operations Research Center, 2018Cataloged from PDF version of thesis.Includes bibliographical references (pages 127-138).In Chapter 1, we design controlled laboratory experiments to investigate whether and how process-driven discussions may improve information sharing, information integration, and the resulting group performance in collective decision making. We first investigate three different conditions on group discussion and find that while suggesting a process (without enforcement) significantly enhances information sharing, enforcing the process is a critical enabler for the group to integrate the shared information into its final decision making and hence improves group performance. We then replicate our results with a more complex task in the context of operations management, and find evidence that the underlying mechanism for process to induce better performance is reduced difficulty and hence lowered mental effort involved in the task. Chapter 2 and 3 focus on supply-chain and governance measures to improve food safety management. In Chapter 2, we employ Heckman's sample selection framework to investigate whether and how structural properties of China's farming supply chains and the strength of governance within the regions in which the supply chains operate jointly influence the risks of economically motivated adulteration (EMA) of food products. We find that both supply chain dispersion and weak local governance are associated with higher EMA risks. In Chapter 3, we further explore a set of innovative transparency measures for quantifying the strength of governance in food safety, which are designed based on data scraped from relevant government websites.by Shujing Wang.Ph.
