An improved model for the formation times of dark matter haloes
No full textA dark matter halo is said to have formed when at least half its mass
has been assembled into a single progenitor. With this definition, it is
possible to derive a simple but useful analytic estimate of the
distribution of halo formation times. The standard estimate of this
distribution depends on the shape of the conditional mass function - the
distribution of progenitor masses of a halo as a function of time. If
the spherical collapse model is used to estimate the progenitor mass
function, then the formation times one infers systematically
underestimate those seen in numerical simulations of hierarchical
gravitational clustering. We provide estimates of halo formation which
may be related to an ellipsoidal collapse model. These estimates provide
a substantially better description of the simulations. We also provide
an alternative derivation of the formation time distribution which is
based on the assumption that haloes increase their mass through binary
mergers only. Our results are useful for models which relate halo
structure to halo formation

Habitus (Fig. 1) elongate oblong oval, nearly parallel sided with continuous outline, broadest in 1/3 of elytral length, slightly convex. Dorsal surface shiny. Coloration. Head rufous, darker (almost blackish) around eyes and medially between eyes, lighter on clypeus, labrum and medially on vertex. Pronotum rufous, infuscate on disc, lighter laterally. Elytra testaceous, somewhat darker in striae; numerous dark punctures present along basal and apical parts of elytral striae 1–5, and along sides of elytra. Ventral part rufous; abdomen dark. Appendages testaceous. Head. Moderately broad, ca. 0.7× width of pronotum, transversely elliptical. Labrum emarginate medially. Anterior margin of clypeus slightly concave. Antennae with antennomeres slender, club-shaped, antennomere I longest. Eyes emarginate anterolaterally. Reticulation consisting of fine, well impressed isodiametric polygonal meshes. Numerous short, deep and isolated strioles present between eyes. Punctation double; several large setigerous punctures present in fronto-clypeal depressions, frontal depressions at level of anterior margin of eyes, and in depressions along inner margin of eyes; very fine and sparsely distributed punctures placed among meshes of microreticulation. Pronotum. Transverse, broadest at posterior angles. Anterior angles acute, posterior angles rectangular. Sides slightly and evenly curved, with lateral beading very thin and indistinct. Anterior margin straight, posterior margin nearly straight with only indistinct sinuation medially. Reticulation similar to that of head, but slightly less impressed. Disc of pronotum with numerous deep irregular strioles of variable length. Punctation double; row of coarse setigerous punctures presents along anterior margin, basal margin (except medially), and laterally close to sides; fine punctures placed among meshes of microreticulation, denser than on head. Scutellar shield broadly triangular. Elytra. Elytral striation consisting of twelve discal striae: stria 1 shorter, ending at ca. 4/5 of elytral length; stria 2 longest; striae 7, 9 and 12 shorter apically, ending at ca. 3/4–4/5 of elytral length; stria 11 shortest, beginning more posteriorly than other striae and present only in basal third of elytral length. Surface reticulation consisting of fine, shallowly impressed isodiametric polygonal meshes. Punctation double; few large setigerous punctures present along elytral striae, but predominantly along lateral margin of elytra; very fine, sparsely distributed punctures placed among meshes of microreticulation, similar to those on pronotum. Legs. Protibia modified, angled near base, distinctly broadened anteriorly, club shaped. Pro- and mesotarsomeres 1–3 distinctly broadened, ventrally with adhesive setae. Ventral side. Prosternum sinuate anteriorly, obtusely keeled medially. Prosternal process shortly lanceolate, in cross-section convex, apex obtuse; process distinctly bordered laterally; reticulation almost effaced except some superficial meshes apically. Metaventrite with microsculpture consisting of polygonal meshes; numerous short, oblique, deep strioles present laterally but absent medially; lateral parts of metaventrite ('metasternal wings') tongue-shaped, slender. Metacoxal lines well impressed, nearly complete—absent only close to metaventrite. Metacoxal plates covered with long, deep longitudinal strioles; reticulation consisting of extremely elongate, longitudinal polygonal meshes. Metacoxal processes rounded and incised at posterior margin. Abdominal ventrites I–II with longitudinal strioles; ventrites III–IV with oblique strioles laterally. Tuft of setae present antero-medially on ventrites III–V; ventrite VI with setigerous punctures laterally on either side. Abdominal reticulation consisting of elongate polygonal meshes, longitudinal on ventrites I–II, oblique on ventrite III and transverse on ventrites IV– VI. Punctation consisting of fine, sparsely distributed punctures. Male genitalia. Median lobe in lateral aspect broad in basal 3/4, then narrowing to pointed apex; almost evenly curved except at base (Fig. 17). A fold present till subapical region. Parameres 'D'-shaped, apex very narrow and long; apical lobe long (Fig. 18). Female. Females do not differ in external morphology from male except for nearly straight, apically less broadened protibia, and slender pro- and mesotarsi without adhesive setae. Additionally, we have studied two females with elytral stria 11 absent, thus they have only eleven striae on each elytron. Variability. The specimens of the type series vary in coloration, especially infuscation of head and pronotum (from rufous to nearly black) and elytra (from testaceous to reddish brown). A form with longitudinal striolation on elytra occurs in both males and females of this species (Fig. 2): strioles long, often confluent, distinctly less impressed than striae; present between all striae, but missing in apical fourth of elytral length. Striolate form differs from the typical specimens also in strioles on the pronotum, which are usually longer and denser than those in nonstriolate form. Measurements (N = 31). TL: 5.3–6.9 mm (holotype: 6.1 mm); Tl-h: 4.8–6.4 mm (holotype: 4.9 mm); MW: 2.0–3.0 mm (holotype: 2.7 mm). Differential diagnosis. Based on the presence of 11–12 dorsal elytral striae and absent submarginal stria, the new species can be classified within the Copelatus nigrolineatus species group sensu Guéorguiev (1968). This group so far contains only five species (Nilsson & Hájek 2018): C. flavicans Guignot, 1952 and C. luctuosus Guignot, 1939 occurring in the Neotropical region, C. nigrolineatus Sharp, 1882 from Australia, C. zimmermanni Gschwendtner, 1934 distributed in China and Japan, and C. schuhi Hendrich & Balke, 1998 known so far only from Maharashtra (India). The new species differs from C. schuhi by its large size, 5.3–6.9 mm (body length ranges between 4.0– 4.5 in C. schuhi); elytral striae extending apically (elytral striae are missing the in apical third in C. schuhi); pale basal transverse elytral band absent (broad and distinct pale band present in C. schuhi); and the different shape of the median lobe, which is in lateral view, broad in the basal 3/4, then narrowing to a pointed apex (Fig. 17), and almost evenly curved except at the base (median lobe of C. schuhi is unevenly curved in lateral view, its outer margin is slightly sinuate; subapically broad; abruptly pointed at apex, see Fig. 19). Etymology. The new species is named after the Deccan plateau, a large volcanic basalt plateau in southern India, which covers most of the territory of Maharashtra state. Mani (1974) referred to Maharashtra as the 'Deccan Lavas Country'. The specific epithet is an adjective in the nominative case. Collecting circumstances. This species appears to inhabit isolated, clean water bodies. The specimens were collected in a side pool of a stream (Fig. 40), an ephemeral puddle with decaying leaves (Fig. 41) and muddy substrate, in remnant pools with pebbles as substrate formed in drying streams (Fig. 39); also in nearly permanent man-made tanks and small puddles (Fig. 42) on basaltic rocks. The physicochemical parameters of water bodies range as follows: pH: 6.2 to 9.0, temperature 18 to 25 0C and salinity 23 to 115 ppm. Distribution. The species was found in Pune, Nashik, Ahemadnagar districts of Maharashtra (Fig. 45). Collected within an altitude range of 500–1,215 m a.s.l.Published as part of Sheth, Sayali D., Ghate, Hemant V. & Hájek, Jiří, 2018, Copelatus Erichson, 1832 from Maharashtra, India, with description of three new species and notes on other taxa of the genus (Coleoptera: Dytiscidae: Copelatinae), pp. 235-260 in Zootaxa 4459 (2) on pages 237-243, DOI: 10.11646/zootaxa.4459.2.2, http://zenodo.org/record/145854

Contribution of JAM-1 to epithelial differentiation and tight-junction biogenesis in the mouse preimplantation embryo
No full textWe have investigated the contribution of the tight junction (TJ) transmembrane protein junction-adhesion-molecule 1 (JAM-1) to trophectoderm epithelial differentiation in the mouse embryo. JAM-1-encoding mRNA is expressed early from the embryonic genome and is detectable as protein from the eight-cell stage. Immunofluorescence confocal analysis of staged embryos and synchronized cell clusters revealed JAM-1 recruitment to cell contact sites occurred predominantly during the first hour after division to the eight-cell stage, earlier than any other TJ protein analysed to date in this model and before E-cadherin adhesion and cell polarization. During embryo compaction later in the fourth cell cycle, JAM-1 localized transiently yet precisely to the apical microvillous pole, where protein kinase C (PKC) and PKC are also found, indicating a role in cell surface reorganization and polarization. Subsequently, in morulae and blastocysts, JAM-1 is distributed ubiquitously at cell contact sites within the embryo but is concentrated within the trophectoderm apicolateral junctional complex, a pattern resembling that of E-cadherin and nectin-2. However, treatment of embryos with anti-JAM-1-neutralizing antibodies indicated that JAM-1 did not contribute to global embryo compaction and adhesion but rather regulated the timing of blastocoel cavity formation dependent upon establishment of the trophectoderm TJ paracellular seal
