    No full text
    The existence and best L2-bounds for the Wiener type integrals , where X ranges through a wide class of Bessel-like centered processes, and f belongs to L2([0,1]), are discussed in terms of Fourier transforms associated with some characteristics of X, thus providing some unification of previous results on this topic obtained by the authors [T. Funaki, Y. Hariya, M. Yor, Wiener integrals for centered powers of Bessel processes, I, Markov Processes and their Related Fields (2006) (in press), T. Funaki, Y. Hariya, F. Hirsch, M. Yor, On the construction of Wiener integrals with respect to certain pseudo-Bessel processes, Stochastic Processes and their Applications (2006) (in press)] as well as yielding new results.Wiener integrals Quadratic forms Tempered distributions Optimal bounds

    AbstractIn previous papers [T. Funaki, Y. Hariya, M. Yor, Wiener integrals for centered powers of Bessel processes, I, Markov Processes Related Fields (2006) (in press); T. Funaki, Y. Hariya, M. Yor, Wiener integrals for centered Bessel and related processes, II, Alea (2006) (in press)], the authors have shown that it is possible to define the Wiener-type integrals ∫01h(s)dR¯s, for every h∈L2([0,1],ds) and (R¯s) any centered Bessel process with dimension d>1. In this paper, various conditions are stated, showing that such a construction is possible for a large class of processes indexed by two square integrable Brownian functionals. In particular, some of the results previously obtained for the Bessel processes are thus recovered, and in fact shown to extend to certain processes of the form tf(Rtt)

    Review of the book “Autonomy and selfgovenrment in Diverse America”, Miguel González, Aracely Burguete, Pablo Mariman y Ritzuko Funaki (eds.), Quito, Abya Yala, 2021.  The book fills a gap in contemporary literature by analysing ongoing processes of autonomy implemented by indigenous and Afro-descendant peoples in different national contexts in the Americas. It also offers a critical view of  recognition policies regarding indigenous rights in the perspective of plurinational and plural States. Based on concrete experiences of selgovernment, it reports on the innovations and renewed strength of indigenous peoples to exercise their right to self-determination. Keywords: autonomies, self-government, indigenous peoples, Diverse America.Reseña del libro Autonomías y autogobierno en la América Diversa, Miguel González, Aracely Burguete, Pablo Mariman y Ritzuko Funaki (eds.), Quito, Abya Yala, 2021.  El libro llena un vacío en la literatura contemporánea al presentar una  diversidad de procesos que implementan los pueblos indígenas y afrodescendientes en los distintos contextos nacionales en las Américas. Ofrece asimismo una mirada crítica en torno a las políticas de reconocimiento y sus alcances en perspectiva de los Estados plurinacionales y plurales, pero también desde experiencias concretas da cuenta de las innovaciones y la renovada fuerza de las comunidades y pueblos indígenas para ejercer su derecho a la libredeterminación.

    Y. Susuki, N. Kawamoto, Y. Ohashi, A. Ishigame, T. Funaki and S. D’Arco, "A Modular Approach to Large-Signal Modeling of an Interconnected AC/MTDC System," 2020 IEEE PES Innovative Smart Grid Technologies Europe (ISGT-Europe), The Hague, Netherlands, 2020, pp. 945-949, doi: 10.1109/ISGT-Europe47291.2020.9248890.The so-called modular modeling of interconnected AC/MTDC (Multi-Terminal DC) systems aids their synthesis and analysis by decomposing it into structural modules (e.g. voltage-source converter, synchronous generator, AC line, DC line) and by exploring the patterns of interconnection that yield the overall performance of a system. In this paper, we introduce our idea on the modular modeling of large-signal dynamics for an interconnected AC/MTDC system. Effectiveness of the idea is shown with numerical simulations for a relatively simple configuration of three-terminal DC grid

However, its geographic distribution is becoming widespread. Here, we present a Japanese male who resided in the United States for 1 year, where he was diagnosed with pulmonary coccidioidomycosis that was accompanied by cavity formation. He did not tolerate antifungal therapy and consequently underwent partial resection of the upper lobe of his left lung upon his return to Japan. The patient’s symptoms improved after surgery. The trend toward global networking and logistics means that a diagnosis of coccidioidomycosis should be considered in routine practice in nonendemic areas. Due to the rarity of surgical treatment for this disease, prolonged follow-up is necessary. During the last follow-up, the patient was symptom-free.Keywords: coccidioidomycosis, Coccidioides immitis, Coccidioides posadasii, endemic diseas
