The sexual identity of 4395 Neurons is important for courtship.
No full text<p>(A, B) Feminization of <i>4395-Gal4</i> expressing cells by the expression of <i>UAS-traF</i> reduces male courtship (A), indicating that these cells are sexually dimorphic. In contrast, conditional feminization in adult 5-day old males does not affect male courtship (B). (C). Expression of <i>4395-RNAi</i> in the mushroom bodies using the <i>P247-Gal4</i> driver does not affect courtship. N = 10.</p
Localization of cells that express both fru and 4395-Gal4.
No full text<p>(A–F) Brains of adult <i>UAS-lacZ<sup>nls</sup>/lexAop::GFP<sup>nls</sup>; 4395-Gal4/fruP1LexA</i> males were double-stained with anti-β-Gal (magenta) and anti-GFP (green) to identify cells expressing both <i>fru</i> and <i>hector</i>. Although this GFP carries a nuclear localization signal (nls), diffusion of the protein is also seen into the projections. Co-staining is observed in numerous cell bodies in the mb area. (A, D: merged images, B, C, E, F: single images). A–C show the Z-stack of a whole brain, D–F show a representative magnified optical section in the area of the mb calyx. (G–K) Triple staining of <i>UAS-lacZ<sup>nls</sup>/lexAop::GFP<sup>nls</sup>; 4395-Gal4/fruP1LexA</i> males with anti-β-Gal (blue), anti-GFP (green) and anti Dco (red) shows that cells that express both <i>fru</i> and <i>hector</i> are mushroom body cells. Co-staining is shown in G, single channels are shown in M, N, O. (L–Q) Brains of adult <i>UAS-mcD8::GFP/4395-Gal4; lexAop-myr-mCherry/fruP1LexA</i> were co-stained with anti-GFP (magenta) and anti-RFP (green). The projections of the neurons can be seen. In contrast to <i>4395-Gal4</i>, <i>fru</i>, in addition to expression in the α, β and γ lobes, is also expressed in the α′ and β′ lobes. (L′) shows a magnification at the level of the β and γ lobes that visualizes overlap as well as close proximity of the labeled projections. (O–Q) Colocalization of <i>fru</i> and <i>4395-Gal4</i> staining in glomeruli of the antennal lobes. 4395-Gal4 projections are visible in all <i>fru</i> positive glomeruli.</p

Is there a sub-parsec-scale jet base in the nearby dwarf galaxy NGC 4395?
Get PDFNGC 4395 is a dwarf galaxy at a distance of about 4.3 Mpc (scale: ∼0.021 pc mas-1). It hosts an intermediate-mass black hole (IMBH) with a mass between ∼104 and ∼105 solar masses. The early radio observations of NGC 4395 with the very long baseline interferometry (VLBI) network, High Sensitivity Array (HSA), at 1.4 GHz in 2005 showed that its nucleus has a sub-mJy outflow-like feature (E) extending over 15 mas. To probe the possibility of the feature E as a continuous jet with a base physically coupled with the accretion disc, we performed deep VLBI observations with the European VLBI Network (EVN) at 5 GHz, and analysed the archival data obtained with the HSA at 1.4 GHz in 2008, NSF's Karl G. Jansky Very Large Array (VLA) at 12-18 GHz and the Atacama Large Millimetre/submillimetre Array (ALMA) at 237 GHz. The feature E displays more diffuse structure in the HSA image of 2008 and has no compact substructure detected in the EVN image. Together with the optically thin steep spectrum and the extremely large angular offset (about 220 mas) from the accurate optical Gaia position, we explain the feature E as nuclear shocks likely formed by the IMBH's episodic ejection or wide-angle outflow. The VLA and ALMA observations find a sub-mJy pc-scale diffuse feature, possibly tracing a thermal free-free emission region near the IMBH. There is no detection of a jet base at the IMBH position in the VLBI maps. The non-detections give an extremely low luminosity of ≤4.7 × 1033 erg s-1 at 5 GHz and indicate no evidence of a disc-jet coupling on sub-pc scales. Astrodynamics & Space Mission
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variability and the Size-Luminosity Relation of the Intermediate-mass AGN in NGC 4395
No full textWe present a variability study of the lowest-luminosity Seyfert 1 nucleus of the galaxy NGC 4395 based on photometric monitoring campaigns in 2017 and 2018. Using 22 ground-based and space telescopes, we monitored NGC 4395 with a similar to 5-minute cadence during a period of 10 days and obtained light curves in the ultraviolet (UV), V, J, H, and K/K-s bands, as well as narrowband H alpha. The rms variability is similar to 0.13 mag in the Swift UVM2 and V filter light curves, decreasing down to similar to 0.01 mag in the K filter. After correcting for the continuum contribution to the H alpha narrow band, we measured the time lag of the H alpha emission line with respect to the V-band continuum as minutes in 2018, depending on assumptions about the continuum variability amplitude in the H alpha narrow band. We obtained no reliable measurements for the continuum-to-continuum lag between UV and V bands and among near-IR bands, owing to the large flux uncertainty of UV observations and the limited time baseline. We determined the active galactic nucleus (AGN) monochromatic luminosity at 5100 A, after subtracting the contribution of the nuclear star cluster. While the optical luminosity of NGC 4395 is two orders of magnitude lower than that of other reverberation-mapped AGNs, NGC 4395 follows the size-luminosity relation, albeit with an offset of 0.48 dex (>= 2.5 sigma) from the previous best-fit relation of Bentz et al.N
