Sensillus uncate. Tutorium weakly developed.</p> <p>Notogaster: Dorsosejugal region with a deep, wide depression, median part of notogaster highly projeeting, its surface divided or ornamented by strong ridges connected with each other.

Opisthocepheus Aoki 1976
No full textOpisthocepheus Aoki, 1977 (Figs 54-56) Aoki, 1977: 45. Prodorsum: Lamellae fused medially and covering the greatest part of prodorsum, their anterior part highly elevated, lamellar setae arising here; interlamellar setae absent.* Sensillus gradually dilated, directed forwards. Tutorium well observable. Notogaster: Dorsosejugal area strongly excavated, dorsosejugal suture indistinct. Posteromedian part of notogaster highly projecting. Thirteen pairs of notogastral setae present, one pair in humeral position. All notogastral setae more or less phylliform. Coxisternal region: Epimeral setal formula: 3 —1—2— 3. Epimeral borders well developed, so all epimeres well framed. Anogenital region: A pair of strong longitudinal ribs ending in a tubercle present. Anogenital setal formula: 4 —1—2— 3. Lyrifissure iad was not mentioned in the original description. Type species: Opisthocepheus kirai Aoki, 1977. Malaysia. * It is also possible, that in fact the "lamellar" setae are the interlamellar ones, and the true lamellar setae are reduced or hardly visible. Remarks: Only the holotype is known.Published as part of Mahunka, S., 1986, A survey of the family Carabodidae C. L.

The First observation of the muonic decay D(s)+- ---> mu+- muon-neutrino.
No full textThe muonic decay of charmed strange mesons has been observed directly, in the analysis of a sample of 144 decays of charged charmed particles into a muon and no other charged particle. The branching ratio is estimated to be BR(Ds± →μ±νμ) = (4.0+1.8+0.8-1.4-0.6 ±1.7) ×10-3, assuming a ratio r = 0.27 between production cross sections of Ds± and neutral charmed particles. The decay constant fDs is estimated to be (232 ±45 ±20 ±48) MeV/c2 and does not depend on theoretical assumptions

Mixozercon stellifer Aoki 1964
No full textMixozercon stellifer (Aoki, 1964) Prozercon stellifer Aoki, 1964: 489. Mixozercon stellifer.― Halašková, 1977: 67; Błaszak, 1979: 85. Diagnosis. Central and submarginal setae of podonotum smooth, except j 1 -j 2, z 2 and s 6 pilose. Setae J 1 -J 4, Z 1 -Z 3 and S 1 short, pilose, other J-, Z- and S-setae longer, densely pilose. Setae R 1 pilose, markedly longer than the others, which are smooth and thorn-like. Setae J 5 situated between dorsal cavities. Opisthonotal setae do not reach the bases of the following setae. Setae S 1 situated posterolaterally to Z 1. Pores Po 2 situated inside the line connecting Z 1 and Z 2. Podonotum covered by circular, squamous pattern, the area between J setal-rows densely ornamented by triangular protuberances forming stellar pattern. Dorsal cavities weakly sclerotised, with undulate anterior margin. Post-genital sclerites absent. Distribution. Japan and possibly Canada. Remarks. On the basis of the figures and descriptions of Aoki (1964) and Halašková (1977), the Japanese and Canadian specimens differ in some characters; for example, the body shape, the shape and length of setae R 1 and some podonotal setae; specially j 2, which is smooth for Canadian specimens, and the J and Z setal rows inserted in bigger setal bases. Therefore we have some doubt that the Palaearctic and Nearctic specimens are conspecific; however, further investigation is necessary.Published as part of Díaz-Aguilar, Irma & Ujvári, Zsolt, 2010, New zerconid mites (Acari: Mesostigmata: Zerconidae) from Canada, with a review of the genus Mixozercon Halašková, 1963, pp. 1-29 in Zootaxa 2555 on page 4, DOI: 10.5281/zenodo.19691
