Stadie (GU 124-2021 Sobczyk). Paratypes: 11 ♂, same data as holotype, 8 ♂, Tunesien, Prov. Kaserine, Wadi am Djebel Chambi, 850 m, 12 km südl. Kaserine 08. –11.x.2006, leg. D. Stadie, J. Gelbrecht & T. Drechsel (in coll. Stadie, Gelbrecht, Drechsel, CTS, CWA, SMNS). Diagnosis. ♂. Wingspan 21.0– 23.5 mm (average: 22.6 mm), forewing length 10.6–11.0 mm, width 5.4–6.0 mm (average 5.6 mm), FI 1.88–1.98 (average 1.94 mm). Head EI 0.72–0.77 (average 0.74). Antennae length 6.2–7.4 mm, 38–43 segments without pedicellus and scapus. The pecten very long, 1.4 mm. The longest pecten 10 times of segment diameter. Thorax and abdomen densely covered with long pale brown hairs. Forewings broad, costal margin almost straight, apex rounded, termen curved. All wings brownish, forewing costal margin darker, thinly scaled with hair-like scales (class 1–2 after Sauter & Hättenschwiler 1999), scales mostly with two dentations, partially with one or three dentations. Fringes lighter greyish brown, long, with 3 dentations, the middle of them mostly broader and larger. Abdomen densely covered with long pale brown hairs. Male genitalia. (GU 124-2021 Sobczyk): 2.1 mm length, elongated in general appearance, tegumen rounded distally, laterally bulging, covered with short hairs. Valvae long and clearly extended beyond the distal end of the tegumen. The valvae are apically rounded and covered with short setae. Sacculus closure elongated, slender, distally narrower and apically with four short thorns.Anellus short, pointed. Vinculum broad, laterally evenly curved. Saccus elongated, slightly wider distally. Phallus longer as genitalia length (2.3 mm), straight or slightly bent, with distinct roundish enlargement caudally, vesica with short cornuti. Discussion. A small species (wingspan 21.0– 23.5 mm) with relatively short and wide wings (FI below 2.0) and thus differ from the similar species (FI above 2.0). The species is also characterized at first glance by its relatively monochrome, densely scaled brown wings. Distribution. As far as known from the type locality in Tunisian. Bionomics. Unknown Etymology. The species is named after the type locality.The Djebel Chambi (arabic: Dschebel asch-Schaʿânabî) is a mountain range with the national park of the same name, in which the highest point in Tunisia is located at 1544 meters.Published as part of Arnscheid, Wilfried R., Rajaei, Hossein & Sobczyk, Thomas, 2021, A taxonomic review of the genus Amicta Heylaerts, 1881 in North Africa, Near and Middle East (Lepidoptera, Psychidae, Oiketicinae, Acanthopsychini), pp. 349-368 in Zootaxa 5071 (3) on page 361, DOI: 10.11646/zootaxa.5071.3.3, http://zenodo.org/record/572376

Measurement of the ratio of prompt χ c to J / ψ production in pp collisions at √s = 7 TeV
No full textThe prompt production of charmonium χ c and J / ψ states is studied in proton-proton collisions at a centre-of-mass energy of √s = 7 TeV at the Large Hadron Collider. The χ c and J / ψ mesons are identified through their decays χ c → J / ψ γ and J / ψ → μ + μ - using 36 pb - 1 of data collected by the LHCb detector in 2010. The ratio of the prompt production cross-sections for χ c and J / ψ, σ (χ c → J / ψ γ) / σ (J / ψ), is determined as a function of the J / ψ transverse momentum in the range 2 < p T J / ψ < 15 GeV / c. The results are in excellent agreement with next-to-leading order non-relativistic expectations and show a significant discrepancy compared with the colour singlet model prediction at leading order, especially in the low p T J / ψ region
Evidence for the decay B0→J/ψω and measurement of the relative branching fractions of meson decays to J/ψη and J/ψη′
No full textFirst evidence of the B 0 → J / ψ ω decay is found and the B s 0 → J / ψ η and B s 0 → J / ψ η ′ decays are studied using a dataset corresponding to an integrated luminosity of 1.0 fb -1 collected by the LHCb experiment in proton-proton collisions at a centre-of-mass energy of sqrt(s) = 7 TeV. The branching fractions of these decays are measured relative to that of the B 0 → J / ψ ρ 0 decay:frac(B (B 0 → J / ψ ω), B (B 0 → J / ψ ρ 0)) = 0.89 ± 0.19 (stat) - 0.13 + 0.07 (syst),frac(B (B s 0 → J / ψ η), B (B 0 → J / ψ ρ 0)) = 14.0 ± 1.2 (stat) - 1.5 + 1.1 (syst) - 1.0 + 1.1 (frac(f d, f s)),frac(B (B s 0 → J / ψ η ′), B (B 0 → J / ψ ρ 0)) = 12.7 ± 1.1 (stat) - 1.3 + 0.5 (syst) - 0.9 + 1.0 (frac(f d, f s)), where the last uncertainty is due to the knowledge of f d / f s, the ratio of b-quark hadronization factors that accounts for the different production rate of B 0 and B s 0 mesons. The ratio of the branching fractions of B s 0 → J / ψ η ′ and B s 0 → J / ψ η decays is measured to befrac(B (B s 0 → J / ψ η ′), B (B s 0 → J / ψ η)) = 0.90 ± 0.09 (stat) - 0.02 + 0.06 (syst)
Diagnostic of induction machines by d-q and i.s.c. rotor models
No full textRecently both d-q and instantaneous symmetrical components (i.s.c.) models for faulty cage induction machines have been proposed for numerical simulations of stator instantaneous currents. Applying FFT algorithm to stator current the sideband components at frequencies (1±2s)f can be evaluated. The amplitudes of these components are commonly used as diagnostic index to assess rotor condition in the MCSA diagnostic procedures. With the assumption of infinite machine-load combined inertia value or ideal speed control the speed ripple due to rotor asymmetry will not be present. Steady-state conditions can be considered and only the component at frequency (1-2s)f will appear. If the above assumption does not hold, the (1-2s)f component correspond to the sum of the two sideband lines. In any case the parameterization, i.e. the definition of an asymmetry factor used as diagnostic index to define the fault severity, is a key item. The simplest asymmetry factor may be the definition of an equivalent additional resistance ΔRr linked to the number of contiguous broken bars. In this paper the proposals about the quantization of ΔR r found in the literature are reviewed and compared with reference to one broken bar. A new proposal is also presented and its effectiveness is proven
DNA fusion gene vaccination mobilizes effective anti-leukemic cytotoxic T lymphocytes from a tolerized repertoire
No full textThe majority of known human tumor-associated antigens derive from non-mutated self proteins. T cell tolerance, essential to prevent autoimmunity, must therefore be cautiously circumvented to generate cytotoxic T cell responses against these targets. Our strategy uses DNA fusion vaccines to activate high levels of peptide-specific CTL. Key foreign sequences from tetanus toxin activate tolerance-breaking CD4+ T cell help. Candidate MHC class Ibinding tumor peptide sequences are fused to the C terminus for optimal processing and presentation. To model performance against a leukemia-associated antigen in a tolerized setting, we constructed a fusion vaccine encoding an immunodominant CTL epitopederived from Friend murine leukemia virus gag protein (FMuLVgag) and vaccinated tolerant FMuLVgag-transgenic (gag-Tg) mice. Vaccination with the construct induced epitopespecificIFN-c-producing CD8+ T cells in normal and gag-Tg mice. The frequency and avidity of activated cells were reduced in gag-Tg mice, and no autoimmune injury resulted. However, these CD8+ T cells did exhibit gag-specific cytotoxicity in vitro and in vivo. Also, epitope-specific CTL killed FBL-3 leukemia cells expressing endogenous FMuLVgag antigen and protected against leukemia challenge in vivo. These results demonstrate a simple strategy to engage anti-microbial T cell help to activate epitope-specific polyclonal CD8+ T cell responses from a residual tolerized repertoire

The other contains the handwritten manuscript "Iliad of the Family," as well as mathematical equations and scientific essays.Biographical/Historical Note: A Mobile, Alabama, author, J. T. Wiswall published two books,
