Type loc.: Balut Is., Mindanao Sea, Philippines, ca 30 m, coralline bottom. Syn. Nov. Description: Shell fusiform (b/l 0.29–0.38), with short, straight siphonal canal (a/l 0.39–0.46), last whorl with rounded periphery, spire straight-sided to slightly cyrtoconoid, whorls convex, without peripheral angle, suture somewhat deep but narrow; outer lip evenly convex, with 6–9 strong spiral threads inside, anal sinus relatively shallow, slightly V-shaped. Sculptured by well-defined, but rather low and narrow spiral cords, their intervals with thin intermediary threads roughened by crinkled collabral threads. Subsutural cord relatively low, bearing an angular thread, with a weaker one on either side; sulcus very narrow and deep. Sinus cord above median, nearly as prominent as peripheral cord, declivously flattened, bearing 2 spiral threads, strongly crenulate but not gemmulate. Base of penultimate whorl with 2–3 anterior cords, the peripheral cord not particularly prominent, the 3 rd cord sometimes weak. Base of last whorl with very approximately 15–25, some weaker and paler, with finer threads in intervals, fine to obsolete on tip of rostrum. Collabral threads distinct, rendering basal cords somewhat granular. White to pale brown with main spiral ridges orange-brown; protoconch white. Protoconch (f. Vera-Peláez et al. 2000) papilliform, ca 3.5 convex whorls, with arcuate, opisthocline axial riblets, suture covered by a thin, white ridge. Attains 90.5 mm in length. DISTRIBUTION: SW Japan to Southern Philippines and Papua New Guinea, depth reportedly 30 m to ca 360 m. TYPES: G. lululimi: Holotype and one juvenile paratype presently in BO colln. T. munizi: Holotype in Vera-Lozano colln. OTHER MATERIAL EXAMINED: JAPAN: off Cape Shiona, Wakayama Prefecture, 150–200 m (Shingo Habu colln, ex Akira Inada); off Irino, Kochi Prefecture, 120–130 m (Shingo Habu colln). PHILIPPINES: Oslob, S.

REMARKS: Superficially, this species appears to be intermediate in characters between Gemmula and Turris, but has a sinus cord that is low and non-peripheral, and distinctly crenulate, not truly gemmulate as in the former. G. lululimi appears to be characterised by the brown ridges on a white ground, its short siphonal canal and the strongly crenulated sinus cord.Published as part of Kilburn, Richard N., Fedosov, Alexander E. & Olivera, Baldomero M., 2012, Revision of the genus Turris Batsch, 1789 (Gastropoda: Conoidea: Turridae) with the description of six new species, pp. 1-58 in Zootaxa 3244 (1) on pages 56-57, DOI: 10.11646/zootaxa.3244.1.1, http://zenodo.org/record/24632
Uniform convergence of proliferating particles to the FKPP equation
No full textIn this paper we consider a system of Brownian particles with proliferation whose rate depends on the empirical measure. The dependence is more local than a mean field one and has been called moderate interaction by Oelschläger [16], [17]. We prove that the empirical process converges, uniformly in the space variable, to the solution of the Fisher–Kolmogorov–Petrowskii–Piskunov equation. We use a semigroup approach which is new in the framework of these systems and is inspired by some literature on stochastic partial differential equations47312752CONSELHO NACIONAL DE DESENVOLVIMENTO CIENTÍFICO E TECNOLÓGICO - CNPQFUNDAÇÃO DE AMPARO À PESQUISA DO ESTADO DE SÃO PAULO - FAPESP460713/2014-02015/04723-2The work of F.

Omega-3 fatty acids increase the unfolded protein response and improve amyloid-β phagocytosis by macrophages of patients with mild cognitive impairment
No full textMacrophages (Mφs) of patients with Alzheimer's disease and mild cognitive
impairment (MCI) are defective in amyloid-β1-42 (Aβ) phagocytosis and have low
resistance to apoptosis by Aβ. Omega-3 fatty acids (ω-3s) in vitro and in vivo
and the ω-3 mediator, resolvin D1, in vitro increase Aβ phagocytosis by Mφs of
patients with MCI. We have investigated the unfolded protein response (UPR) to
endoplasmic reticulum (ER) stress by Mφs in a longitudinal study of fish-derived,
ω-3-supplemented patients with MCI. Patients in the apolipoprotein E (ApoE)e3/e3
subgroup over time exhibited an increase of protein kinase RNA-like ER kinase
(PERK) expression, Aβ phagocytosis, intermediate M1-M2 Mφ type, and a Mini-Mental
State Examination (MMSE) rate of change of +1.8 points per year, whereas patients
in the ApoEe3/e4 subgroup showed individually divergent results with an MMSE rate
of change of -3.2 points per year. In vitro treatment of Mφs by fish-derived ω-3
emulsion increased Aβ phagocytosis, PERK expression, and UPR RNA signature, and
decreased ER stress signature. Augmented genes in the UPR signature included
chaperones, lectins, foldases, and N-linked glycosylation enzymes. In summary,
fish-derived ω-3s increase cytoprotective genes and decrease proapoptotic genes,
improve immune clearance of Aβ, and are associated with an improved MMSE rate of
change in ApoEe3/e3 vs. ApoEe3/e4 patients.-Olivera-Perez, H. M., Lam, L., Dang,

Sous-facteurs de L(F∞) d'indice 4cos2π/n,n≥3
No full textLet Q be a factor of type II1, λ a number in the Jones discrete series {4cosπ/m:m≥3}, and {ei} the Jones projections associated with λ. Denote by A2n and A1n the finite-dimensional von Neumann algebras generated, respectively, by {1,e2,⋯,en} and {1,e1,⋯,en}, with the corresponding traces. The author shows that, for n sufficiently large, the index of the inclusion An=(Q⊗A2n)∗A2nA1n⊂(Q⊗A2n+1)∗A2n+1A1n+1=An+1 is equal to λ (here ∗ denotes the reduced, amalgamated free product of the algebras in question). Using the random matrix model of Voiculescu, he proves that if Q is the von Neumann algebra L(F∞) of the free group with infinitely many generators, then An is isomorphic to L(F∞).
The two facts together imply the existence, for any λ in the Jones discrete series, of an irreducible subfactor of L(F∞) of index λ. This constitutes the first example of a nonhyperfinite, non-Γ II1 factor such that its Jones invariant is fully computable (the existence of nonirreducible subfactors of L(F∞) for any index ≥4 is a simple consequence of known results)

No full textPolitica e amministrazione, tra etica, managerialità e responsabilità
No full textIl volume raccoglie le versioni, approfondite e rielaborate, delle relazioni discusse in occasione del convegno dal titolo “Politica e amministrazione. Etica, managerialità e responsabilità”, organizzato in onore di Gianfranco D’Alessio. L’oggetto di analisi, la dirigenza amministrativa, è discusso e analizzato, da un lato, in relazione ai principi costituzionali di imparzialità e di buon andamento della Pubblica Amministrazione e, dall’altro, al rapporto che questa instaura con gli organi politici. Il tema è affrontato con approcci variegati e da prospettive molteplici, secondo una impostazione che riflette la pluralità delle competenze e delle esperienze, professionali ed accademiche di ciascun autore.The volume collects the expanded and revised versions of the presentations discussed during the conference titled "Politics and Administration. Ethics, Managerialism, and Accountability," organized in honour of Gianfranco D’Alessio. The focus is on administrative leadership, discussed and analysed from two perspectives. Firstly, in relation to the constitutional principles of impartiality and good administration. Secondly, with reference to the relationship it establishes with political bodies. The topic is approached from various angles and multiple perspectives, reflecting the diversity of skills and experiences, both professional and academic, of each author
Logarithmic variance profiles and the corresponding f-1 spectra of temperature fluctuations in turbulent Rayleigh-Bénard convection
No full textWe report experimental results for the temperature variance 2(z) and the corresponding frequency spectra P(f) in turbulent Rayleigh-Bénard convection (RBC) in a cylindrical sample of aspect ratioT= D/L = 1:00 (D = 1:12 m is the diameter and L = 1:12 m the height). The measurements were conducted in the Rayleigh-number range 1011 < Ra < 1:35 1014 and Pr ' 0:8. For Ra = 1:35x1014, 2(z) could be described well by a logarithmic dependence on the vertical position z in a range of z 1 < z < z 2 with z 1 ' 70 and z 2 = 0:1L. Here L=(2Nu) is the thickness of a thin thermal sublayer adjacent to the horizontal plate where the heat flux (denoted by the Nusselt number Nu) is carried mostly by thermal diffusion. In the log layer, we found that the temperature spectra had a significant frequency range over which P(f) f with close to 1. As Ra decreased, increased so that the log layer became thinner. At Ra = 2:05 1011, z 2 < z 1 and therefore there was no range for a log layer. Correspondingly, the temperature spectrum near the horizontal plate did not have the f1 scaling form either
