    No full text
    We study the boundary behavior of the Kobayashi--Fuks metric on the class of h-extendible domains. Here, we derive the non-tangential boundary asymptotics of the Kobayashi--Fuks metric and its Riemannian volume element by the help of some maximal domain functions and then using their stability results on h-extendible local models.Comment: Journal adde

Traditionally, the former is characterized by elytron bearing one tomentose macula and restricted to Taiwan Island (Kobayashi 1990; Qiu <i>et al.</i> 2015), while the latter is totally black and distributed in eastern India and Indochina (Arrow 1910; Qiu <i>et al.</i> 2015). However, we recently obtained a female whose appearance perfectly matches the characteristics of <i>P. formosanus</i> (Fig. 9), but it originated from Guangzhou (Guangdong, China) where located on the southeastern edge of the Asian continent and between the Indochinese Peninsula and Taiwan Island (Fig. 28). Furthermore, an individual of <i>P. formosanus</i> bearing an indistinct macula on elytron (nearly disappeared) was found from Taiwan (Fig. 25), and a female of <i>P. jansoni</i> with two maculae was discovered from Vietnam (Fig. 13). The two specimens have here verified the prediction proposed by Qiu <i>et al.</i> (2015) that the variability of tomentose maculae on elytron can be observed in a species of wide distribution. Therefore, neither endemism of <i>P. formosanus</i> nor morphological differences between the two species are well established, but we would like to formally propose the synonymy when sufficient material got rather than synonymize them at present.</p>Published as part of <i>Qiu, Jian-Yue & Xu, Hao, 2020, Further notes on the flower chafer genus Platysodes Westwood, 1873 (Coleoptera Scarabaeidae: Cetoniinae) with description of a new species from Himalaya, pp. 192-200 in Zootaxa 4890 (2)</i> on page 195, DOI: 10.11646/zootaxa.4890.2.2, <a href="http://zenodo.org/record/4301815">http://zenodo.org/record/4301815</a&gt

The specific epithet, araliella, is derived from the family name of the host plant, Araliaceae. Biology. This species has 2–3 generations per year. The larvae emerged from July to November in Nara and Mie Prefectures. We observed larvae on Evodiopanax innovans forming a narrow, long serpentine mine; about 30 ~ cm in length, clear and colorless. The mines (Fig. 9 A–D) were only found on the abaxial epidermis of leaves, usually 1–3 mines per leaf. The late instar larva is 3.0–4.0 mm long and pale greenish yellow in coloration (Fig. 9 E–G). A pupal cocoon fold (white to creamy white, 4.5 –5.0 mm in length, 0.8 –1.0 mm in width) situated at the end of the mine, usually found along leaf margins (Fig. 9 H). We also observed the mined leaf of Fatsia japonica to be a narrow, long linear mine (whitish, about 20 ~ cm in length; 0.6–5 mm in width; brownish frass line: ~1.0 mm in width) (Fig. 10 C, E, F). A pupal cocoon fold (white, 9.0 mm in length, 2.0 mm in width) situated along leaf margins. Biotope. The Kumawata valley (type locality of E. araliella) is part of Tokai Nature Trail connecting Soni Vilage and Uda City (Murō Vil.), Nara Prefecture with a planted forest of Japanese cedar and cypress mixed with fagaceous trees and with few host plants (Fig. 1 E).Published as part of Kobayashi, Shigeki, Huang, Guo-Hua, Nakamura, Akihiro & Hirowatari, Toshiya, 2013, Four new species of Gracillariidae (Lepidoptera) from China and Japan, and description of the pupal morphology of the genera Corythoxestis, Eumetriochroa, Guttigera, and Metriochroa, pp. 101-129 in Zootaxa 3619 (2) on pages 113-115, DOI: 10.11646/zootaxa.3619.2.1, http://zenodo.org/record/21886

    Platysodes formosanus Kobayashi, 1990 (Figs. 1–5, 42) Platysodes formosanus Kobayashi, 1990: 78 (type locality: Mt. Nanfengshan, Maolin, Kaohsiung, Taiwan), figs. 4 & 8 ♂ (parameres and holotype); Sakai & Nagai 1998: 163 (Puli, Taiwan), plate 5, fig. 111 ♀; Yu et al. 1998: 100, plate 5, fig. 13 ♂ (holotype); Krajčik 1999: 43; Smetana 2006: 300; Krajčik 2012: 213. Diagnosis. This species is similar to P. jansoni. The primary difference is the presence of a small, velvety white macula in the middle of the elytron near the lateral margin, which is absent in P. jansoni. Type material examined. Holotype of Platysodes formosanus Kobayashi, 1990 is labeled: “ HOLOTYPE [P.], Platysodes formosanus [H.] H. Kobayashi [P.], (1990) [H.], [red label with black border]/ Nanfengshan, Maolin, Taiwan [P.], May 10 [H.] 1986, Ching-Kin Yu leg. [P.], [white label]” (♂, MSMT, Figs. 1–5). Comments on type material. Platysodes formosanus was described by Kobayashi based on a single male specimen, and it is preserved in his personal collection as he indicated in the original publication (Kobayashi 1990). However, the holotype was not found in a recent search (Mr. Hirokazu Kobayashi, personal communication). As indicated in the original description, the holotype was collected by “ Y. Ching” (incorrect spelling of Ching-Kin Yu) from Mt. Nanfengshan in Kaohsiung Hsien, Taiwan. The late Mr. Ching-Kin Yu (1926– 2012) was curator of the collections of MSMT where a considerable number of his specimens are deposited, the holotype of P. formosanus may also preserved there. This supposition later was confirmed by our colleague, Mr. Yu-Tang Wang, who found a male specimen with a holotype label is perfectly in accord with the original publication. Other material examined.

Distribution. Taiwan. Remarks. Platysodes formosanus is endemic to Taiwan, and only five specimens are known to us. Both bear only one small, white macula in the center of the elytron near the lateral margin.Published as part of Qiu, Jian-Yue, Xu, Hao & Chen, Li, 2015, Review of the Oriental genus Platysodes Westwood (Coleoptera: Scarabaeidae: Cetoniinae: Cremastocheilini) with a redescription of Platysodes madoni Bourgoin, pp. 553-564 in Zootaxa 4021 (4) on page 555, DOI: 10.11646/zootaxa.4021.4.5, http://zenodo.org/record/24095

    External cavity modes in Lang-Kobayashi and traveling wave models

    No full text
    We investigate a semiconductor laser with delayed optical feedback due to an external cavity formed by a regular mirror. We discuss similarities and differences of the well-known Lang-Kobayashi delay differential equation model and the traveling wave partial differential equation model. For comparison we locate the continuous wave states in both models and analyze their stability

    A Determination of the Cabibbo-Kobayashi-Maskawa Parameter |Vus|_ Using KL Decays

    No full text
    The KTev experiment was performed at Fermilab to determine the Cabibbo-Kobayashi-Maskawa parameter |Vus| based on new measurements of the six largest KL branching fractions and semileptonic forms factors. The |Vus| was found to be equivalent to 0.2252±0. 0008KTeV±0.0021ext , where the errors were from KTeV measurements and from external sources. The CP violation parameter |η+-|=(2.228±0.005fKTeV±0.009 ext) ×10-3 was determined using the measured branching fractions. The results indicate that the improved form factor measurements may help to reduce theoretical uncertainties in f+(0)
