Lopes & Kano (1979) provided a conspectus of <i>Sarcorohdendorfia</i> with a key to species recognized by them as belonging to this taxon plus their possible close relatives. They studied the female holotype of the nominal species <i>Phalacrodiscus whitneyi</i> Curran, and although they noted the similarity with <i>S. imitatrix</i> (Baranov), they considered <i>P. whitneyi</i> not to be conspecific with the latter because “females of <i>imitatrix</i> show broad transverse marks on second abdominal tergite” (Lopes & Kano 1979: 658). However, based on the material available for the present study (see below), we consider <i>Chrysosarcophaga imitatrix</i> Baranov, 1938 to be a senior synonym of <i>Phalacrodiscus whitneyi</i> Curran, 1936, <b>syn. nov.</b> Both have Guadalcanal Island as their type locality, and species-specific features in the abdominal colour pattern and the distribution of pale and dark setae on gena and postgena provide an exact match.</p>Published as part of <i>Geisler, Lucas & Pape, Thomas, 2023, Two new species of the ' Big Yellows' (Diptera: Sarcophagidae: Sarcophaga), pp. 190-202 in Zootaxa 5311 (2)</i> on page 191, DOI: 10.11646/zootaxa.5311.2.2, <a href="http://zenodo.org/record/8094188">http://zenodo.org/record/8094188</a>
Maternal Depression, Women's Empowerment, and Parental Investment: Evidence from a Randomized Controlled Trial
No full textWe evaluate the medium-term impacts of treating maternal depression on women's mental health, financial empowerment, and parenting decisions. We leverage variation induced by a cluster-randomized controlled trial that provided psychotherapy to 903 prenatally depressed mothers in rural Pakistan. It was one of the world's largest psychotherapy interventions, and it dramatically reduced postpartum depression. Seven years after psychotherapy concluded, we returned to the study site to find that impacts on women's mental health had persisted, with a 17 percent reduction in depression rates. The intervention also improved women's financial empowerment and increased both time- and money-intensive parental investments by between 0.2 and 0.3 standard deviations

Type material examined. Mehria pseudobenaci: Lectotype 3, herewith designated to fix unambiguously the identity of the nominal species and thus promote nomenclatural stability: Serbia / Golubaz [= Golubac] / 27.V. 1929 // N.

V. 1934 [sic!]; 2 3: 28.IV. 1936 (all USNM). Remarks. Baranov (1942: 618) described Mehria pseudobenaci on an unspecified number of specimens from Golubac (Serbia), collected in May-June. I consider the above-listed type specimens (from the Baranov collection at USNM) to constitute all or part of the type series of M. pseudobenaci. The lectotype was selected for its overall better condition, as several of the other specimens are severely covered in mould.

Additional material examined. Greece: Makhedonia, Thessaloniki, Hortiatis, 30.V. 2002, P. Cerretti et al. leg., 2 3 (CNBFVR); nr. Stávros, VI. 1997, Farkač leg., 9 3 (ZMUC). Diagnosis (3). Sarcophaga (Heteronychia) pseudobenaci is a medium-small species (ca. 4.5– 7mm) with a narrow frons (ca. 0.35–0.40 times eye width at narrowest point) and narrow parafacial (0.15–0.20 times eye width); lower facial margin not visible in lateral view; postgenal setulae entirely white; occipital setulae white behind first two rows; scutellum with a pair of apical setae; wing vein R 1 bare on dorsal surface; abdomen with dense grey microtrichosity, lateral black markings somewhat interrupted medially in posterior view; abdominal tergite 3 with a pair of strong median marginal setae; epandrium dark brown/black; cercus (Fig. 66) with a rounded subapical hump and a slightly downcurved, pointed tip; cercus uniformly covered with sparse setae; distiphallus (Fig. 67): proximal part of harpes rounded in lateral view; apical processes flat, tapering and directed ventrally; juxta short, with blunt, receding lateral processes; tip of juxta (Fig. 68) narrow, with short, blunt lateral processes; lateral styli slender, at most slightly protruding beyond juxta; vesica well visible in lateral view, with large rounded corners and a bulging central part. Differential diagnosis. Species similar and possibly closely related to Sarcophaga (H.) benaci (Figs 69–71), from which it can be distinguished by the presence of median marginal setae on tergite 3 and by the shape of the cercus and distiphallus; in particular, the tip of juxta is much wider in S. (H.) benaci (Fig. 71). Sarcophaga (H.) pseudobenaci could also be confused with S. (H.) infantilis, especially due to similarities in the shape of the cercus (compare Figs 66 and 72), but it can be distinguished from the latter by the bare dorsal surface of wing vein R 1 and the distinctly concave dorsal surface of juxta in lateral view (compare Figs 67 and 73). Remarks. Sabrosky and Crosskey (1970: 430) did not locate syntypes of Mehria pseudobenaci in USNM. As a consequence, Verves (1986) and Pape (1996) listed pseudobenaci as a doubtful and unidentified species of Heteronychia, respectively. Verves (1986) synonymized Heteronychia drenskiana with H. ostensackeni (= S. (H.) infantilis); direct comparison of type specimens showed that H. drenskiana is a junior synonym of Sarcophaga (H.) pseudobenaci. The species is known, so far, from Bulgaria, Greece and Serbia.Published as part of Whitmore, Daniel, 2011, New taxonomic and nomenclatural data on Sarcophaga (Heteronychia) (Diptera: Sarcophagidae), with description of six new species, pp. 1-57 in Zootaxa 2778 on pages 46-48, DOI: 10.5281/zenodo.20188
Measurement of J/Ψ production in pp collisions at √s=7 TeV
No full textThe production of J/psi mesons in proton-proton collisions at root s = 7 TeV is studied with the LHCb detector at the LHC. The differential cross-section for prompt J/psi production is measured as a function of the J/psi transverse momentum p(T) and rapidity y in the fiducial region p(T) is an element of [0; 14] GeV/c and y is an element of [2.0; 4.5]. The differential cross-section and fraction of J/psi from b-hadron decays are also measured in the same p(T) and y ranges. The analysis is based on a data sample corresponding to an integrated luminosity of 5.2 pb(-1). The measured cross-sections integrated over the fiducial region are 10.52 +/- 0.04 +/- 1.40(-2.20)(+1.64) mu b for prompt J/psi production and 1.14 +/- 0.01 +/- 0.16 mu b for J/psi from b-hadron decays, where the first uncertainty is statistical and the second systematic. The prompt J/psi production cross-section is obtained assuming no J/psi polarisation and the third error indicates the acceptance uncertainty due to this assumption

Measurement of the differential cross-section of B+ meson production in pp collisions at root s=7 TeV at ATLAS
No full textThe production cross-section of B+ mesons is measured as a function of transverse momentum p T and rapidity y in proton-proton collisions at centre-of-mass energy root s = 7 TeV, using 2.4 fb(-1) of data recorded with the ATLAS detector at the Large Hadron Collider. The differential production cross-sections, determined in the range 9 GeV < p(T) < 120 GeV and vertical bar y vertical bar < 2.25, are compared to next-to-leading-order theoretical predictions
Mie-resonant mesoporous electron transport layer for highly efficient perovskite solar cells
No full textAll-dielectric nanophotonics is a powerful tool for improvement of thin-film optoelectronic devices because of low optical losses, strong light localization, and chemical robustness against such materials as halide perovskites. However, large-scale and low-cost approaches to create functional nanostructures are still not developed. In our work, we show a novel method to create mesoporous electron transport layer based on optically resonant silicon nanoparticles incorporated into TiO2 paste to be applied for perovskite (MAPbI(3)) solar cell. The inclusion of Mie-resonant silicon nanoparticles helps to improve light absorption by a perovskite layer without reduction of the active material. The management of Si nanoantennas concentration provides to reach a power conversion efficiency higher than 21% by increasing all main device parameters. Our multi-physical theoretical simulations of the solar cells with the resonant silicon nanoparticles provide physical understanding on the mechanisms of the device improvement as well as help to optimize the silicon nanoparticles concentration
Measurements of Physicochemical Characteristics of Atmospheric Aerosol at Research Station Ice Base Cape Baranov in 2018
No full textWe discuss the results of measurements in the region of Cape Baranov (the Severnaya Zemlya archipelago) of the set of physicochemical characteristics of atmospheric aerosol: aerosol optical depth, aerosol and black carbon concentrations, elemental and ion compositions of aerosol, organic and elemental carbon contents in aerosol, as well as the isotopic composition of carbon in the aerosol and snow samples. It is shown that the average values of most aerosol characteristics, measured in April–June 2018, are a little lower than in the Arctic settlement Barentsburg (Spitsbergen archipelago) and several-fold smaller than in the south of Western Siberia in the same period
Observation of double charm production involving open charm in pp collisions at sqrt{s}=7 TeV
No full textThe production of J/Ψ mesons accompanied by open charm, and of pairs of open charm hadrons are observed in pp collisions at a centre-of-mass energy of 7TeV using an integrated luminosity of 355 pb -1 collected with the LHCb detector.
