    Let (X,d,μ)(X,d,\mu) be a RCD(K,N)RCD^\ast(K, N) space with KRK\in \mathbb{R} and N[1,]N\in [1,\infty]. For N[1,)N\in [1,\infty), we derive the upper and lower bounds of the heat kernel on (X,d,μ)(X,d,\mu) by applying the parabolic Harnack inequality and the comparison principle, and then sharp bounds for its gradient, which are also sharp in time. When N=N=\infty, we also establish a sharp upper bound of the heat kernel by using the dimension free Harnack inequality. For applications, we study the large time behavior of the heat kernel, the stability of solutions to the heat equation, and show the LpL^p boundedness of (local) Riesz transforms.Comment: 27pp,Section 6 was removed, to appear in Potential Ana

    Presently precision forestry is playing an important role in realizing sustainable development and improving societal and economical efficiency for forestry applications. Based on analyzing the features of precision forestry's information requirements, the data needed for precision forestry were classified and the characteristics of the different information were summarized. Data fusion for precision forestry was studied in this paper. The architecture for precision forestry information processing, which integrated information fusion and data mining, was put forward. New and emerging technologies such as Remote Sensing (RS), Geographical Information System (GIS), Global Position System (GPS), Data Base Management System (DBMS), Data Fusion, Decision Support Systems (DSS), and Variable Rate technology (VRT) are applied in forestry production as aids in producers' and managers' decision-making process. Precision irrigation, precision fertilizing, precision pesticide application, precision harvesting, and precision deforestation can promote the realization of minimizing resource inputs, minimizing environmental impacts, and maximizing forest outputs

    breath, void, ground

    Before the sound, there is breath. Before the explosion, there is a threshold. Before the noise, there is silence. Inspired by the physicality of balloons, this thesis explores breath as sonic material that carries memory, moves through bodies, and resonates across spaces. The balloon becomes a skin that holds breath: a force inhaling trauma, ritual, and intimacy. When released through mouth and latex, breath conjures alien, untranslatable voices that hiss and hum. It begins with a balloon and expands with endless breath. The balloon becomes a site where the history, body, and voice disintegrate and reform. The pressure and tension between skins generate vibration, touching the body and its surroundings. It is a breathing and sonic practice, not of positioning or grounding the floating self, but of exploring nomadic ways of being in, of, and as a void that resonates between bodies

    A Cognitive and Cross-Linguistic Approach to Polysemy

    Get PDF
    Polysemy refers to the phenomenon that a word possesses multiple different but related meanings. Past accounts have provided descriptions of the relations that an extended sense may have to the most central or fundamental ( core ) sense of a word, but they do not provide an explanatory account of how such senses are generated. The current research investigates the cognitive basis for the generation of polysemous senses. I hypothesize that extended senses are built on the salient characteristics of referents of core senses. I also argue that to the extent that speakers of different languages find the same characteristics of default referents salient, different languages should tend to generate similar polysemous senses from the same core senses. Evidence is provided for this proposed language-independent mechanism using data from six psycholinguistic tasks administered to speakers of two historically unrelated languages: English and Chinese. I also propose that, assuming a bidirectional interaction between language and thought, more embodied words should generate a larger number of extended senses and a higher proportion of senses shared between the languages. Evidence is provided for these predictions through the same empirical tasks. Broadly, this project provides a novel avenue for the study of word senses by revisiting the cognitive link between thought and language

    Exploration of Experiment Teaching Reform Guided by the Engineering Education Philosophy

    In order to make the electronic design contest and reform of experiment teaching to support and promote each other and improve students' practical and innovative ability, the paper analyzed the requirements on the students' ability of comprehensive knowledge application and practice by NUEDC, and the deficiencies of the depth and scope of electronic information professional practice curriculum. Use the issues-based, project-based and case-based engineering education philosophy and teaching methods as orientation. The way of practice teaching reform and the effect of the reform from six aspects are also discussed: the construction of hierarchy practice teaching system, the seminar and the optimizing of teaching content, the engineering teaching method, the experimental teaching environment and full control of network-assisted teaching platform. DOI: http://dx.doi.org/10.11591/telkomnika.v11i8.3144 

    Effect of “HuChou San” on ABCC11 mRNA levels and MRP8 protein expression in skin tissue from bilateral axilla of axillary osmidrosis patients

    Purpose: To investigate the effect of “HuChou San” on axillary osmidrosis (AO) by measuring ABCC11 mRNA levels and MRP8 protein expression in axillary skin tissues from “HuChou San”-treated AO patients.Methods: Forty AO patients undergoing treatment at Shanghai Ninth People’s Hospital were enrolled in the study. Tissues from axillary regions were initially treated for 10 min with a solution of copper sulphate and zinc sulphate, followed by treatment with gentle application of “HuChou San” once daily for 3 months. Ten healthy individuals served as untreated control. Axillary skin tissue was surgically collected at 0, 1, 2, and 3 months of treatment. The expressions of ABCC11 mRNA and MRP8 protein in axillary skin samples were determined using qPCR and Western blot, respectively.Results: The qPCR and Western blot results showed higher levels of ABCC11 mRNA and MRP8 protein in AO patient tissues than in healthy controls. However, “HuChou San” treatment markedly reduced tissue levels of ABCC11 mRNA and MRP8 protein (p < 0.05), when compared to tissues extracted prior to treatment. These effects were time-dependent and increased as treatment duration increased (p < 0.05).Conclusion: “HuChou San” powder significantly and time-dependently reduced ABCC11 mRNA and MRP8 protein expressions in AO axillary tissue of AO patients. It is known that ABCC11 mRNA and MRP8 protein are two important indices of AO. Therefore, the findings of this study suggest that“HuChou San” has potentials for use as a novel alternative therapy for AO. Keywords: ABCC11 mRNA, MRP8 protein, Axillary osmidrosis, HuChou Sa
