description: Following a serendipitous detection with the NuSTAR observatory, we present a multi-epoch spectral and temporal analysis of an extreme ultraluminous X-ray source (ULX) located in the outskirts of the Circinus galaxy, hereafter Circinus ULX5, including coordinated follow-up observations with XMM-Newton and NuSTAR. The NuSTAR data presented here represent one of the first instances of a ULX reliably detected at hard (E>10 keV) X-rays. Circinus ULX5 is variable on long timescales by at least a factor of ~5 in flux, and was caught in a historically bright state during our 2013 observations (0.3-30.0 keV luminosity of 1.6e40 erg/s). During this epoch, the source displayed a curved 3-10 keV spectrum, broadly similar to other bright ULXs. While in many cases the interpretation of spectral components in ULXs is uncertain, the spectral and temporal properties of the all the high quality datasets currently available strongly support a simple disk-corona model reminiscent of that invoked for Galactic binaries, with the accretion disk becoming more prominent as the luminosity increases. However, although the disk temperature and luminosity are remarkably well correlated across all timescales currently probed, the observed luminosity follows T^(1.70+/-0.17), flatter than that expected for simple blackbody radiation. The spectral variability displayed by Circinus ULX5 is highly reminiscent of that observed from some known Galactic black hole binaries (BHBs) at high luminosities. This comparison would imply a black hole mass of ~90 Msun for Circinus ULX5. However, given the diverse behavior observed from Galactic BHB accretion disks, this mass estimate is still uncertain. Finally, the limits placed on any undetected iron absorption features with the 2013 dataset imply that we are not viewing the central regions of Circinus ULX5 through any extreme super-Eddington outflow.

description: Two methods can be used to calculate explicitly the Killing form on the Lie algebras. The first one is a direct calculation of the traces of the generators in a matrix representation of the algebra, and the second one is the usage of the group invariance of the scalar product. We use both methods in our calculation of the scalar product on the extended Poincare algebra in order to have a cross check of our results. The algebra is infinite-dimensional and requires careful treatment of the infinities. The scalar product on the extended algebra found by both methods coincides and the important conclusion which follows is that Poincare generators are orthogonal to the gauge generators.

description: How structures, e.g., magnetic loops, in the upper atmosphere, i.e., the transition region and corona, are heated and sustained is one of the major unresolved issues in solar and stellar physics. Various theoretical and observational studies on the heating of coronal loops have been undertaken. The heating of quiescent loops caused by eruptions is, however, rarely observed. In this study, employing data from the Solar Dynamics Observatory (SDO) and Solar Upper Transition Region Imager (SUTRI), we report the heating of quiescent loops associated with nearby eruptions. In active regions (ARs) 13092 and 13093, a long filament and a short filament, and their overlying loops are observed on 2022 September 4. In AR 13093, a warm channel erupted toward the northeast, whose material moved along its axis toward the northwest under the long filament, turned to the west above the long filament, and divided into two branches falling to the solar surface. Subsequently, the short filament erupted toward the southeast. Associated with these two eruptions, the quiescent loops overlying the long filament appeared in SDO/Atmospheric Imaging Assembly (AIA) high-temperature images, indicating the heating of loops. During the heating, signature of magnetic reconnection between loops is identified, including the inflowing motions of loops, and the formation of X-type structures and newly reconnected loops. The heated loops then cooled down. They appeared sequentially in AIA and SUTRI lower-temperature images. All the results suggest that the quiescent loops are heated by reconnection between loops caused by the nearby warm channel and filament eruptions.

description: We present a perturbative approach to derive the semiclassical equations of motion for the two-dimensional electron dynamics under the simultaneous presence of static electric and magnetic fields, where the quantized Hall conductance is known to be directly related to the topological properties of translationally invariant magnetic Bloch bands. In close analogy to this approach, we develop a perturbative theory of two-dimensional photonic transport in gyrotropic photonic crystals to mimic the physics of quantum Hall systems. We show that a suitable permittivity grading of a gyrotropic photonic crystal is able to simulate the simultaneous presence of analog electric and magnetic field forces for photons, and we rigorously derive the topology-related term in the equation for the electromagnetic energy velocity that is formally equivalent to the electronic case. A possible experimental configuration is proposed to observe a bulk photonic analog to the quantum Hall physics in graded gyromagnetic photonic crystals.

With almost 7,500 species, this is one of the richest Diptera families (Evenhuis & Pape 2020). Rondani (1846b, 1848b, 1850 c, 1851, 1856, 1863, 1868b, 1873e, 1873f, 1875c) described 25 Neotropical, 11 Oriental, seven Palaearctic, one Afrotropical nominal species and one without any indication of the type locality, mostly from material collected by others and sent to him for identification. Rondani did not cover this family in his Prodromus. Thirty-one species are currently considered as valid but these include unexamined types whose taxonomic position is doubtful (Martin 1968, Martin & Papavero 1970, Oldroyd 1975, Artigas & Angulo 1980, Oldroyd 1980, Lehr 1988, Scarbrough 1993, Contini et al. 1995, Papavero 2009), two as senior synonyms and 12 as junior synonyms. Rondani (1848 b, 1863) proposed three new replacement names for species previously described and named by P.J.M. Macquart. In his paper on the Rondani types at MZUB, Morge (1959b) listed five unpublished names (nomina nuda) of Rondani. Scarbrough (1993) designated a lectotype of Ommatius costatus Rondani, 1850 in the MRSN, a collection also examined by N. Papavero who, however, did not formally designate any lectotype. Here, we designate a lectotype for Habropogon doriae Rondani, 1873, Promacus taeniopus Rondani, 1873. Except for the type material of six nominal species, which are presumed lost, most of it deriving from the G. Osculati collection in Milan, which Leonardi et al. (1995: 148) and Mazzotti (2011: 166) reported as destroyed, the type material has been recovered for all nominal species and is distributed among the MSNG (15), MZUN (14), MRSN (five), MZUF (two), MNHN (one) and MZUB (one).

description: Since it can describe the rotation curves of galaxies without dark matter and can give rise to accelerated expansion, conformal gravity attracts much attention recently. As a theory of modified gravity, it is important to test conformal gravity with astrophysical observations. Here we constrain conformal gravity with SNIa and Hubble parameter data and investigate whether it suffers from an age problem with the age of APM~08279+5255. We find conformal gravity can accommodate the age of APM~08279+5255 at 3 $σ$ deviation, unlike most of dark energy models which suffer from an age problem.

description: The current generation of advanced gravitational wave detectors utilize titania-doped tantala/silica multilayer stacks for their mirror coatings. The properties of the low-refractive-index silica are well known; however, in the absence of detailed direct measurements, the material parameters of Young's modulus and coefficient of thermal expansion (CTE) of the high refractive index material, titania-doped tantala, have been assumed to be equal to values measured for pure tantala coatings. In order to ascertain the true values necessary for thermal noise calculations, we have undertaken measurements of Young's modulus and CTE through the use of nanoindentation and thermal-bending measurements. The measurements were designed to assess the effects of titania doping concentration and post-deposition heat-treatment on the measured values in order to evaluate the possibility of optimizing material parameters to further improve thermal noise in the detector. Young's modulus measurements on pure tantala and 25% and 55% titania-doped tantala show a wide range of values, from 132 to 177 GPa, dependent on both titania concentration and heat-treatment. Measurements of CTE give values of (3.9 +/- 0.1) x 10^-6 K^-1 and (4.9 +/- 0.3) x 10^-6 K^-1 for 25% and 55% titania-doped tantala, respectively, without dependence on post-deposition heat-treatment.

description: [abridged] We explore the possibility that the dark matter (DM) component in galaxies may originate fractional gravity. In such a framework, the standard law of inertia continues to hold, but the gravitational potential associated to a given DM density distribution is determined by a modified Poisson equation including fractional derivatives (i.e., derivatives of non-integer type), that are meant to describe non-local effects. We derive analytically the expression of the potential that in fractional gravity corresponds to various spherically symmetric density profiles, including the Navarro-Frenk-White (NFW) distribution that is usually exploited to describe virialized halos of collisionless DM as extracted from $N-$body cosmological simulations. We show that in fractional gravity the dynamics of a test particle moving in a cuspy NFW density distribution is substantially altered with respect to the Newtonian case (i.e., basing on the standard Poisson equation), mirroring what in Newtonian gravity would instead be sourced by a density profile with an inner core. We test the fractional gravity framework on galactic scales, showing that: (i) it can provide accurate fits to the stacked rotation curves of galaxies with different properties; (ii) it can reproduce to reasonable accuracy the observed shape and scatter of the radial acceleration relation (RAR); (iii) it can properly account for the universal surface density and the core radius vs. disk scale-length scaling relations. Finally, we discuss the possible origin of the fractional gravity behavior as a fundamental or emerging property of the elusive DM component.

description: Fabricating biomaterials with antimicrobial activity to prevent the growth of detrimental microorganisms is of great scientific and practical interest. Here, composite materials comprising recombinant spider silk proteins and mesoporous silica nanoparticles (MSN) loaded with selected antibiotics and antimycotics are fabricated into films and hydrogels. The derived composite materials exhibit excellent antimicrobial properties with sustained release of antibiotics over the course of 15 days. Furthermore, antibiotics/antimycotics inclusion does not impair the cytocompatibility of the composite materials, all of which promote fibroblast cell adhesion and proliferation. Finally, processing of spider silk–MSN composite hydrogels using 3D printing is shown to enable the fabrication of patient‐specific antimicrobial implants to prevent infection in the near future.

description: The development of graphene electronics requires the integration of graphene devices with Si-CMOS technology. Most strategies involve the transfer of graphene sheets onto silicon, with the inherent difficulties of clean transfer and subsequent graphene nano-patterning that degrades considerably the electronic mobility of nanopatterned graphene. Epitaxial graphene (EG) by contrast is grown on an essentially perfect crystalline (semi-insulating) surface, and graphene nanostructures with exceptional properties have been realized by a selective growth process on tailored SiC surface that requires no graphene patterning. However, the temperatures required in this structured growth process are too high for silicon technology. Here we demonstrate a new graphene to Si integration strategy, with a bonded and interconnected compact double-wafer structure. Using silicon-on-insulator technology (SOI) a thin monocrystalline silicon layer ready for CMOS processing is applied on top of epitaxial graphene on SiC. The parallel Si and graphene platforms are interconnected by metal vias. This method inspired by the industrial development of 3d hyper-integration stacking thin-film electronic devices preserves the advantages of epitaxial graphene and enables the full spectrum of CMOS processing.

TYPE MATERIAL: not found in this study.
CURRENT STATUS: valid species, as Lastaurus bombimorpha (Martin & Papavero 1970: 29); junior synonym of Lastaurus fallax (Macquart, 1846) (Papavero 2009: 73).
REMARKS: Rondani (1851: 368) described Dasipogon bombimorpha from just the female sex, giving a single measurement of length, from material collected by Osculati (1850) during his journey through equatorial South America. Osculati (1850: 240) named but did not describe the species. Leonardi et al. (1995: 148) and Mazzotti (2011: 166) reported the Osculati collection in Milan as destroyed. We also did not find any material during this study. Rondani described this nominal species under the generic name Dasipogon, which is a misspelling of Dasypogon Meigen, 1803 or subsequent usage of Dasipogon Dufour, 1833 (O’Hara et al. 2011: 71).

description: We present the results of a search of infrared excess candidates in a comprehensive (29\,000 stars) magnitude limited sample of dwarf stars, spanning the spectral range F2-K0, and brighter than V$=$15 mag. We searched the sample within the {\em WISE} all sky survey database for objects within 1 arcsecond of the coordinates provided by SIMBAD database and found over 9\,000 sources detected in all {\em WISE} bands. This latter sample excludes objects that are flagged as extended sources and those images which are affected by various optical artifacts. For each detected object, we compared the observed W4/W2 (22$μ$m/4.6$μ$m) flux ratio with the expected photospheric value and identified 197 excess candidates at 3$σ$. For the vast majority of candidates, the results of this analysis represent the first reported evidence of an IR excess. Through the comparison with a simple black-body emission model, we derive estimates of the dust temperature, as well as of the dust fractional luminosities. For more than 80% of the sample this temperature is higher than 120 K, suggesting the presence of warm circumstellar dust. Complementary observations at longer wavelengths (far-IR and sub-mm) are required for better characterising and explaining the origin of this emission.

description: Purpose: Biophysical models of diffusion MRI have been developed to characterize microstructure in various tissues, but existing models are not suitable for tissue composed of permeable spherical cells. In this study we introduce Cellular Exchange Imaging (CEXI), a model tailored for permeable spherical cells, and compares its performance to a related Ball \& Sphere (BS) model that neglects permeability. Methods: We generated DW-MRI signals using Monte-Carlo simulations with a PGSE sequence in numerical substrates made of spherical cells and their extracellular space for a range of membrane permeability. From these signals, the properties of the substrates were inferred using both BS and CEXI models. Results: CEXI outperformed the impermeable model by providing more stable estimates cell size and intracellular volume fraction that were diffusion time-independent. Notably, CEXI accurately estimated the exchange time for low to moderate permeability levels previously reported in other studies ($κ<25μm/s$). However, in highly permeable substrates ($κ=50μm/s$), the estimated parameters were less stable, particularly the diffusion coefficients. Conclusion: This study highlights the importance of modeling the exchange time to accurately quantify microstructure properties in permeable cellular substrates. Future studies should evaluate CEXI in clinical applications such as lymph nodes, investigate exchange time as a potential biomarker of tumor severity, and develop more appropriate tissue models that account for anisotropic diffusion and highly permeable membranes.

Ghiliani and received from G. Mussino. Costa (1866: 36) listed a single MZUN specimen (as Gonipes [sic!]) numbered “785”. We also found one syntype in this study. Although Rondani (1848b: 63) only gave the type locality as “ Brasile ”, Papavero (1973: 343) gave a more accurate type locality based on a note in Spinola (1853) that said all specimens collected by Ghiliani in 1846 were collected in Belem, Pará, Brazil.

description: Recent observations for three types of astrophysical systems severely challenge the GR plus dark matter scenario, showing a phenomenology which is what modified gravity theories predict. Stellar kinematics in the outskirts of globular clusters show the appearance of MOND type dynamics on crossing the $a_{0}$ threshold. Analysis shows a ``Tully-Fisher'' relation in these systems, a scaling of dispersion velocities with the fourth root of their masses. Secondly, an anomaly has been found at the unexpected scales of wide binaries in the solar neighbourhood. Binary orbital velocities cease to fall along Keplerian expectations, and settle at a constant value, exactly on crossing the $a_{0}$ threshold. Finally, the inferred infall velocity of the bullet cluster is inconsistent with the standard cosmological scenario, where much smaller limit encounter velocities appear. This stems from the escape velocity limit present in standard gravity; the ``bullet'' should not hit the ``target'' at more than the escape velocity of the joint system, as it very clearly did. These results are consistent with extended gravity, but would require rather contrived explanations under GR, each. Thus, observations now put us in a situation where modifications to gravity at low acceleration scales cease to be a matter of choice, to now become inevitable.

description: During the CAATEX KV Svalbardcruise14/8–9/9,2019to the North Pole, NORCE operated a fixed-wing unmanned aircraft system (UAS), which was used to collect high-precision optical imagery, providing information about ice morphology and sea-ice properties. Furthermore, NORCE operated an ultra-wideband radar system on a multirotor UAS platform in collaboration with UiT and CIRFA. The radar, which can detect layers in the snow and ice, was operated along selected profiles where also snow and ice samples were collected (Norwegian Polar Institute). In addition, NORCE operated an imaging radar on board KV Svalbard. The radar system, which was mainly operated during the periods where the vessel was stationary in the ice, provided information about ice drift and ice conditions. The main objective of the experiment was to collect observations of sea ice drift and ice coverage and type, at different positions along the route up to 90°N. In addition to the science data collection, the potential of using a high-resolution imaging Ku-band radar for navigation in ice-infested waters was also demonstrated. During the cruise, CIRFA tasked high-resolution Radarsat-2 satellite SAR scenes which were used during the cruise for navigation. NORCE also participated in daily processing and interpretation of satellite SAR imagery from Sentinel-1, which was instrumental in the navigational decision-making process. This combination of data was collected to develop a real-time ice navigation support system.The campaign was co-financed by the Research Council of Norway (RCN )projects ARCEx, CAATEX and CIRFA in addition to the INTAROS Horizon2020 project and the RESICE project funded by the Norwegian Ministry of Climate and Environment. The results formed the foundation for the ProjectDigital Arctic Shipping, a bilateral Norway-China project on developing a drone and satellite-based ice navigation support system. Key stakeholders will be ship operators wanting to use the northern sea routes for transport between the far east and Europe as well as expedition cruise operators and fishing vessels operating close to the ice edge

description: Radiation detectors with noble gasses as the active medium are becoming increasingly common in experimental programs searching for physics beyond the standard model. Nearly all of these experiments rely to some degree on collecting scintillation light from noble gasses. The VUV wavelengths associated with noble gas scintillation mean that most of these experiments use a fluorescent material to shift the direct scintillation light into the visible or near UV band. We present an overview of the R&D program at LBL related to noble gas detectors for neutrino physics, double beta decay, and dark matter. This program ranges from precise measurements of the fluorescence behavior of wavelength shifting films, to the prototyping of large are VUV sensitive light guides for multi-kiloton detectors.

description: Recent advancements in language models and pre-trained language models like BERT and RoBERTa have revolutionized natural language processing, enabling a deeper understanding of human-like language. In this paper, we explore enhancing recommender systems using textual embeddings from pre-trained language models to address the limitations of traditional recommender systems that rely solely on explicit features from users, items, and user-item interactions. By transforming structured data into natural language representations, we generate high-dimensional embeddings that capture deeper semantic relationships between users, items, and contexts. Our experiments demonstrate that this approach significantly improves recommendation accuracy and relevance, resulting in more personalized and context-aware recommendations. The findings underscore the potential of PLMs to enhance the effectiveness of recommender systems.

description: Gonypus clavistilus Rondani, 1848
ORIGINAL DESCRIPTION: 1848b: 96.
TYPE LOCALITY: “ Brasile [Brazil]” (Rondani 1848b: 63); [Belem (Pará), Brazil] (Papavero 1973: 343). See Remarks.
TYPE MATERIAL: 1 specimen, syntype (sex not determinable, missing left wing and fore-legs, abdomen broken) (MZUN: Box Asilidei A 05, 04): Gonypus clavistilus Rnd., Brasile / M. Zool. N° 11075.
CURRENT STATUS: valid species, as Leptogaster clavistilus (Martin 1968: 3, Papavero 2009: 108).
REMARKS: Rondani (1848b: 96) described Gonypus clavistilus, without specifying either the number or the sex of the specimens, but giving a single measurement of length, from material collected in South America by V. Ghiliani and received from G. Mussino. Costa (1866: 36) listed a single MZUN specimen numbered “786”. We also found one syntype in this study. The subsequent spelling “ clavistylus ” has been used (Costa 1866: 36, Williston 1891: 68, Hull 1962: 299, Martin 1968: 3, Papavero 2009: 108) but it is not in prevailing usage (Kertész 1909a: 51, O’Hara et al. 2011: 206). Therefore, the original spelling “ clavistilus ” is to be used and “ clavistylus ” is an incorrect subsequent spelling. Although Rondani (1848b: 63) only gave the type locality as “ Brasile ”, Papavero (1973: 343) gave a more accurate type locality based on a note in Spinola (1853) that said all specimens collected by Ghiliani in 1846 were collected in Belem, Pará, Brazil.

description: The concept of entropy is not uniquely relevant to the statistical mechanics but among others it can play pivotal role in the analysis of a time series, particularly the stock market data. In this area sudden events are especially interesting as they describe abrupt data changes which may have long-lasting effects. Here, we investigate the impact of such events on the entropy of financial time series. As a case study we assume data of polish stock market in the context of its main cumulative index. This index is discussed for the finite time periods before and after outbreak of the 2022 Russian invasion of Ukraine, acting as the sudden event. The analysis allows us to validate the entropy-based methodology in assessing market changes as driven by the extreme external factors. We show that qualitative features of market changes can be captured quantitatively in terms of the entropy. In addition to that, the magnitude of the impact is analysed over various time periods in terms of the introduced entropic index. To this end, the present work also attempts to answer whether or not the recent war can be considered as a reason or at least catalyst to the current economic crisis.

description: The ubiquitous interstellar turbulence regulates star formation and the scaling relations between the initial velocity differences and the initial separations of stars. We propose that the formation of wide binaries with initial separations $r$ in the range $\sim 10^3~\text{AU} \lesssim r \lesssim 10^5$ AU is a natural consequence of star formation in the turbulent interstellar medium. With the decrease of $r$, the mean turbulent relative velocity $v_\text{tur}$ between a pair of stars decreases, while the largest velocity $v_\text{bon}$ at which they still may be gravitationally bound increases. When $v_\text{tur} < v_\text{bon}$, a wide binary can form. In this formation scenario, we derive the eccentricity distribution $p(e)$ of wide binaries for an arbitrary relative velocity distribution. By adopting a turbulent velocity distribution, we find that wide binaries at a given initial separation generally exhibit a superthermal $p(e)$. This provides a natural explanation for the observed superthermal $p(e)$ of the wide binaries in the Solar neighborhood.

description: This work is concerned with the exact controllability/observability of abstract cascade hyperbolic systems by a reduced number of controls/observations. We prove that the observation of the last component of the vector state allows to recover the initial energies of all of its components in suitable functional spaces under a necessary and sufficient condition on the coupling operators for cascade bi-diagonal systems. The approach is based on a multi-level energy method which involves $n$-levels of weakened energies. We establish this result for the case of bounded as well as unbounded dual control operators and under the hypotheses of partial coercivity of the $n-1$ coupling operators on the sub-diagonal of the system. We further extend our observability result to mixed bi-diagonal and non bi-diagonal $n+p$-coupled cascade systems by $p+1$ observations. Applying the HUM method, we derive the corresponding exact controllability results for $n$-coupled bi-diagonal cascade and $n+p$-coupled mixed cascade systems. Using the transmutation method for the wave operator, we prove that the corresponding heat (resp. Schrödinger) multi-dimensional cascade systems are null-controllable for control regions and coupling regions which are disjoint from each other and for any positive time for $n \le 5$ for dimensions larger than $2$, and for any $n \ge 2$ in the one-dimensional case. The controls can be localized on a subdomain or on the boundary and in the one-dimensional case the coupling coefficients can be supported in any non-empty subset of the domain.

description: Using the Finite-Difference-Time-Domain (FDTD) method, we compute the electromagnetic field distribution in and around dielectric media of various shapes and optical properties. With the aid of the constitutive relations, we proceed to compute the bound charge and bound current densities, then employ the Lorentz law of force to determine the distribution of force-density within the regions of interest. For a few simple cases where analytical solutions exist, these solutions are found to be in complete agreement with our numerical results. We also analyze the distribution of fields and forces in more complex systems, and discuss the relevance of our findings to experimental observations. In particular, we demonstrate the single-beam trapping of a dielectric micro-sphere immersed in a liquid under conditions that are typical of optical tweezers.

Non-planar corrections in orbifold/orientifold $\mathcal N=2$ superconformal theories from localization

description: We study non-planar corrections in two special $\mathcal N=2$ superconformal $SU(N)$ gauge theories that are planar-equivalent to $\mathcal N=4$ SYM theory: two-nodes quiver model with equal couplings and $\mathcal N=2$ vector multiplet coupled to two hypermultiplets in rank-2 symmetric and antisymmetric representations. We focus on two observables in these theories that admit representation in terms of localization matrix model: free energy on 4-sphere and the expectation value of half-BPS circular Wilson loop. We extend the methods developed in arXiv:2207.11475 to derive a systematical expansion of non-planar corrections to these observables at strong 't Hooft coupling constant $λ$. We show that the leading non planar corrections are given by a power series in $λ^{3/2}/N^2$ with rational coefficients. Sending $N$ and the coupling constant $λ$ to infinity with $λ^{3/2}/N^2$ kept fixed corresponds to the familiar double scaling limit in matrix models. We find that in this limit the observables in the two models are related in a remarkably simple way: the free energies differ by the factor of $2$, whereas the Wilson loop expectation values coincide. Surprisingly, these relations hold only at strong coupling, they are not valid in the weak coupling regime. We also discuss a dual string theory interpretation of the leading corrections to the free energy in the double scaling limit suggesting their relation to curvature corrections in type IIB string effective action.

description: Absolute photodetachment cross sections of two anions of astrophysical importance CN- and C3N- were measured to be (1.18 +- (0.03)_stat (0.17)_sys) * 10^-17 cm^2 and (1.43 +- (0.14)_stat (0.37)_sys) * 10^-17 cm^2 respectively at the ultraviolet wavelength of 266 nm (4.66 eV). These relatively large values of the cross sections imply that photodetachment can play a major role in the destruction mechanisms of these anions particularly in photon-dominated regions. We have therefore carried out model calculations using the newly measured cross sections to investigate the abundance of these molecular anions in the cirumstellar envelope of the carbon-rich star IRC+10216. The model predicts the relative importance of the various mechanisms of formation and destruction of these species in different regions of the envelope. UV photodetachment was found to be the major destruction mechanism for both CN- and C3N- anions in those regions of the envelope, where they occur in peak abundance. It was also found that photodetachment plays a crucial role in the degradation of these anions throughout the circumstellar envelope.

description: We study propagation of high-frequency wave packets along a large-scale background wave which evolves according to dispersionless hydrodynamic equations for two variables (fluid density and flow velocity). Influence of the wave packet on evolution of the background wave is neglected, so the large-scale evolution can be found independently of the wave packet's motion. At the same time, propagation of the packet depends in essential way on the background wave and it can be considered in framework of geometric optics approximation with the use of Hamilton equations for the carrier wave number and the mean coordinate of the packet. We derive equations for the carrier wave number as a function of the parameters which describe the background wave. When they are solved, the path of the packet can be found by simple integration of the Hamilton equation. The theory is illustrated by its application to the problem of propagation of wave packets along expanding large-scale wave which evolution is described by the shallow water equations. In particular, they correspond to the dispersionless limit of the defocusing nonlinear Schrödinger equation, and then the expanding wave can be considered as an expanding cloud of the Bose-Einstein condensate. Reflection of wave packets from upstream flows and their propagation along stationary flows are also discussed. The analytical solutions found for these particular cases agree very well with exact numerical solution of the nonlinear Schrödinger equation.

description: Habropogon doriae Rondani, 1873
ORIGINAL DESCRIPTION: 1873f: 297.
TYPE LOCALITY: “ Persia sept. [northern Persia]”.
TYPE MATERIAL: 1 ♂, lectotype (MSNG): Persia settent.e [northern Persia], 1862–63, Coll. G. Doria / Typus / Habropogon doriae Rndn., ♂ / Habropogon doriae Rndn. 1873, n. sp.
PARALECTOTYPE EXAMINED: 1 ♀ (MSNG): Persia settent.e [northern Persia], 1862–63, Coll. G. Doria / Typus / Habropogon doriae Rndn., ♀.
CURRENT STATUS: valid species (Lehr 1988: 240).
REMARKS: Rondani (1873f: 297) described Habropogon doriae from an unspecified number of specimens collected by G. Doria, without selecting a holotype from among the syntypes. Guiglia (1957: 195) reported the “type” and one “cotype” of Habropogon doriae in the MSNG (♂ ♀. Type and cotype). She unambiguously selected the type (male) and cotype (female), which therefore must be considered, respectively, as the lectotype and paralectotype (I.C.Z.N. 1999: Article 74.5). Raineri & Rey (1996: 29) also considered the MSNG specimens as the “type and cotype”.
