Letter from Mas Sakai to Sakai family, October 12, 1942
No full textTwo letters from Mas Sakai to the Sakai Family, sent from Tanforan Assembly Center, informing the family that he will be leaving for Utah the following day. The letter is laced with sarcasm as Sakai describes living conditions at Tanforan ("it wouldn't be right if I called it a concentration camp would it? After all we get the freedom of the track, don't we?"), and incarcerees' expectations of life at Topaz ("we all look to Utah with a song in our hearts (a funeral march) for there are our golden opportunities. Wonderful, trackless, sand to plant in, and cool refreshing salt water to drink. We especially look forward to the toilets (no seats)").Personal correspondence, organizational records, government documents, publications, and other papers created or collected by Joseph R. Goodman documenting the forced removal and incarceration of Japanese Americans during World War II, as well as organized resistance to incarceration. Included in the collection are records of the Japanese Young Men's Christian Association and the Japanese American Citizens' League in San Francisco, including papers of the Japanese YMCA's executive secretary Lincoln Kanai; Sakai family papers; Goodman's correspondence to and from Japanese American incarcerees, organizations opposing forced removal and incarceration of Japanese Americans, the War Relocation Authority, and others; publications, photographs, and ephemera from the Topaz Relocation Center, where Goodman taught high school; War Relocation Authority records and publications; and newspaper clippings, pamphlets, and reports about forced removal and incarceration created by various government, religious, and civic organizations, in California and nationwide
A revised classification of genera in the subfamily Eucalliacinae Manning & Felder, 1991 [sensu Sakai], with confirmation of the validity of Calliaxiopsis madagassa Sakai & Türkay, 2014 (Decapoda, Thalassinidea auct.)
No full textAbstract
Re-examination of Calliaxiopsis madagassa Sakai & Türkay, 2014, which was regarded by Poore & Dworschak (2017) as Calliaxina madagassa (Sakai & Türkay, 2014), a senior synonym of Calliaxina thomassini Ngoc-Ho, 2014, required the present author to review the subfamily Eucalliacinae Manning & Felder, 1991. This review has resulted in a revised classification of eleven genera including three new ones in this subfamily, and also in the confirmation of the validity of Calliaxiopsis madagassa Sakai & Türkay, 2014.</jats:p

Description. Length of forewing 8.3–9.9mm; forewing expanse 16.9–17.9mm Wing (Figs 1 G, 2 G): Resembling M. moriutii. Male genitalia (Figs 9 A–F): Uncal lobes round; apex of uncus angularly divergent. Valva with concave ventral lobe; inner surface of valva with almost membranous. Phallus almost straight, about 13 times as long as broad in middle. Female genitalia (Figs 9 G–H): Concavity of posterior margin of ostium bursae about 3 / 4 as long as ostium bursae. Lateral margin of ostium bursae slightly concave. Antrum stout and about 3 / 4 as long as apophysis anterioris. Distribution. JAPAN: Honshu (Iwate, Miyagi Nagano, Yamanashi, Shizuoka, Toyama and Hiroshima). Etymology. The name aquilonis, the genitive of aquilo, “north wind” in Latin, and hence associated with cold, refers to the high altitude Tohoku and Chubu distribution of the new species. Specimen examined.

Further examination is required to discriminate the species by appearance. This species is found at high altitudes in Honshu. The larval biology is unknown, and it has not been reported that shiitake mushrooms are injured by this species. In Hiroshima Pref., this species was found from a shiitake mushroom bed log, so that it is possible that this species may be or become a pest. The valva of the male is ventrally concave as in M. ussuriensis, a condition which is not seen in other species. In addition, we found that this species occurs in Hiroshima Pref.. The occurrence at a long distance from Tohoku and Chubu suggests that it may have been distributed by the transportation of bed logs.Published as part of Osada, Yohei, Sakai, Makoto & Hirowatari, Toshiya, 2015, A revision of the genus Morophagoides Petersen (Lepidoptera, Tineidae) from Japan, pp. 351-368 in Zootaxa 3973 (2) on page 363, DOI: 10.11646/zootaxa.3973.2.9, http://zenodo.org/record/23748

The Sakai-Sugimoto soliton
No full textThe Sakai-Sugimoto model is the preeminent example of a string theory description of holographic QCD, in which baryons correspond to topological solitons in the bulk. Here we investigate the validity of various approximations of the Sakai-Sugimoto soliton that are used widely to study the properties of holographic baryons. These approximations include the flat space self-dual instanton, a linear expansion in terms of eigenfunctions in the holographic direction and an asymptotic power series at large radius. These different approaches have produced contradictory results in the literature regarding properties of the baryon, such as relations for the electromagnetic form factors. Here we determine the regions of validity of these various approximations and show how to relate different approximations in contiguous regions of applicability. This analysis clarifies the source of the contradictory results in the literature and resolves some outstanding issues, including the use of the flat space self-dual instanton, the detailed properties of the asymptotic soliton tail, and the role of the UV cutoff introduced in previous investigations. A consequence of our analysis is the discovery of a new large scale, that grows logarithmically with the 't Hooft coupling, at which the soliton fields enter a nonlinear regime. Finally, we provide the first numerical computation of the Sakai-Sugimoto soliton and demonstrate that the numerical results support our analysis. © 2014 The Author(s)
Correct Bounds on the Ising Lace-Expansion Coefficients
No full textThe lace expansion for the Ising two-point function was successfully derived in (Sakai in Commun Math Phys 272:283-344, 2007, Proposition 1.1). It is an identity that involves an alternating series of lace-expansion coefficients. In the same paper, we claimed that the expansion coefficients obey certain diagrammatic bounds which imply faster x-space decay (as the two-point function cubed) above the critical dimension d(c) (= 4 for finite-variance models) if the spin-spin coupling is ferromagnetic, translation-invariant, summable and symmetric with respect to the underlying lattice symmetries. However, we recently found a flaw in the proof of (Sakai in Commun Math Phys 272:283-344, 2007, Lemma 4.2), a key lemma to the aforementioned diagrammatic bounds. In this paper, we no longer use the problematic (Sakai 2007, Lemma 4.2), and prove new diagrammatic bounds on the expansion coefficients that are slightly more complicated than those in (Sakai 2007, Proposition 4.1) but nonetheless obey the same fast decay above the critical dimension d(c). Consequently, the lace-expansion results for the Ising and phi(4) models in the literature are all saved. The proof is based on the random-current representation and its source-switching technique of Griffiths, Hurst and Sherman, combined with a double expansion: a lace expansion for the lace-expansion coefficients

Megaesthesius sagedai [sic]— Serène 1964b: 176. Not Megaesthesius sagedae Rathbun, 1909. Type material. Depository unknown, Japan, Bungo Strait and Sata-Misaki. Diagnosis. Small size. Carapace (Fig. 19 C; Takeda & Miyake 1969: fig 3; Sakai 1976: fig. 299a) subquadrate; front bilobed, with deep median cleft; dorsal surface with low, spherical tubercles; post-orbital margins sloping to angular anteroexternal angle. Lateral margins straight, parallel to each other, each with 3 or 4 dented regions separated by deep notches, acute tooth on posterior third of margin. Posterior margin nearly straight. Long orbits, eye peduncle elongated (Fig. 19 F; Takeda & Miyake 1969: 4a, b), immobile, cornea reduced, non-pigmented. Antennule greatly enlarged (Fig. 19 C; Takeda & Miyake 1969: 3a; Sakai 1976: fig. 299b), particularly in males. Third maxillipeds (Fig. 34 B; Takeda & Miyake 1969: 4c; Sakai 1976: fig. 299b) nearly fill buccal cavern when closed; merus subovate, ischium subovate, longer than merus; outer margins of merus, ischium unarmed. Chelipeds subequal in length, nearly similar in both sexes; fingers relatively short, not stout; cutting margin of major chela (Fig. 48 E; Takeda & Miyake 1969: 4d) smooth; ventral margin of palm unarmed; ventral surface of cheliped merus with spiniform granules. Proportionally long ambulatory legs (Fig. 19 E; Takeda & Miyake 1969: 4a; Sakai 1976: fig. 299a), P5 merus not reaching front when folded. Distal end of meri of ambulatory legs with minute spinules. Small, acute tooth on inner margin of cheliped carpus of female, ventral surface of cheliped merus smooth in both sexes.

G1 (Fig. 82 G‒H; Takeda & Miyake 1969: 4h, i) slender, distal segment, straight, with spinules. G2, female pleon, thorax, vulvae undescribed. Remarks. Although synonymised by Serène (1964b: 176), there are differences between M. sagedae and M. yokoyai (based on the illustrations by Yokoya 1933 and Takeda & Miyake 1969). The G1 of M. yokoyai is slightly less slender, with more spinules on the distal portion, and a more flared distal segment (Fig. 82 G–I; Takeda & Miyake 1969: fig. 4 g –i) than in M. sagedae (Fig. 82 A, B). The larger chela is thick, high, and the ventral margin and cutting margins are unarmed, with the pollex relatively slender and shorter than the palm in a male (3.5 × 3.8 mm, Fig. 48 E; Takeda & Miyake 1969: fig. 4d) but with the pollex stouter and relatively longer and the cutting margin lined with small teeth in the male specimen on hand of M. sagedae (2.5 × 3.0 mm, ZRC 1995.885; Fig. 48 C).
