description: (Presented by Richard Abdill.) Researchers in the life sciences are posting work to preprint servers at an unprecedented and increasing rate, sharing papers online before (or instead of) publication in peer-reviewed journals. Though the increasing acceptance of preprints is driving policy changes for journals and funders, there is little information about their usage. Here, we collected and analyzed data on all 37,648 preprints uploaded to bioRxiv.org, the largest biology-focused preprint server, in its first five years. We find preprints are being read more than ever before (1.1 million downloads in October 2018 alone) and that the rate of preprints being posted has increased to a recent high of 2,100 per month, driven primarily by exponential growth in the number of papers in neuroscience and bioinformatics. We also find that two-thirds of preprints posted before 2017 were later published in peer-reviewed journals, and that preprints with more downloads tend to appear in journals with a higher impact factor. The age of preprints appearing in journals also differs by publication, with journals such as G3 publishing most preprints within four months of their appearance on bioRxiv. Lastly, we developed Rxivist.org, a web application providing multiple ways of interacting with preprint metadata, including an API and website that allows users to sort preprints related to their interests based on Twitter activity or bioRxiv download metrics.

description: Between 2013 and 2014 research was conducted on the settlement organisation and past landscape of the Neolithic and Copper Age on the Great Hungarian Plain. The main objective was a diachronic examination of the small tell like settlement Berettyóújfalu-Szilhalom and its environs. In the framework of this research different methods were applied to evaluate the archaeological potential of the site and develop perspectives for further research. The preliminary results of this assessment are presented here.

description: Acrylic acid (AA) is a monomer commonly employed in emulsion polymerization to provide electrostatic colloidal stability and improve specific film performance. The addition of AA not only modifies the kinetics of the polymerization, but also it takes part in the interaction between colloidal particles, which has a strong influence on their packing and consequent latex film properties. In this contribution a theoretical modeling of the latex film formation is presented and compared to experimental results: water vapor permeability and latex film capacitance are studied as a function of AA content. It has been shown that water uptake is mainly affected by film morphology which in turn is defined by intercolloidal interaction and drying rate.

description: Auf den ersten Blick ist die Kombination der Werbebanner am imposanten Eingang des Ungarischen Nationalmuseums recht überraschend. Die Plakate machen auf die drei aktuellen Ausstellungen des Museums, die jeweils einen “Helden“ in den Mittelpunkt stellen, aufmerksam: Siebenbürgen-Fürst Gábor Bethlen, Nationaldichter Sándor Petőfi sowie Kriegsfotograf Robert Capa.Die Verbindung zwischen Capa und Budapest, seinem Lebenswerk und seiner Geburtsstadt scheint hergestellt. Aber Capa als der ungarische Nationalheld, als Teil des nationalen Erbes? Glücklicherweise gibt die Ausstellung keine oberflächliche und simple Antwort auf diese Frage. Im Gegenteil: Die Schau, konzipiert durch Èva Fisli, konzentriert sich vielmehr auf einzelne Kategorien, die die Figur “Robert Capa“ und sein Lebenswerk ausmachen. Ganz andere Schwerpunkte, als etwa die Nationalität, stehen dabei im Fokus.

description: The research in the modern district of Kharkiv (East Ukraine) devoted to settlement history of the 4th and 5th century AD in this area has been continued in 2014. The investigations were focused on analyzes of the data and publication of the first results. Based on the surveys of the past few years the distribution of Chernyakhov culture could be recorded more exactly. In Voitenki, an archaeological complex of the Chernyakhov culture, excavations were conducted by the co-operation partner. They brought to light a pottery kiln in the settlement and a number of graves on the cemetery where now 206 graves are known.

description: We discuss the optimization of a neutrino factory for large \sin^2 2 θ_{13}, where we assume minimum effort on the accelerator side. This implies that we use low muon energies for the price of an optimized detection system. We demonstrate that such a neutrino factory performs excellent if combined with the electron neutrino appearance channel. Instead of the platinum channel operated with the muon neutrinos from the muon decays, we propose to use the initial superbeam from the decaying pions and kaons, which might be utilized at little extra effort. Since we assume out-of-phase bunches arriving at the same detector, we do not require electron charge identification. In addition, we can choose the proton energy such that we obtain a synergistic spectrum peaking at lower energies. We find that both the superbeam and the neutrino factory beam should used at the identical baseline to reduce matter density uncertainties, possibly with the same detector. This effectively makes the configuration a single experiment, which we call ``neutrino factory superbeam''. We demonstrate that this experiment outperforms a low-energy neutrino factory or a wide band beam alone beyond a simple addition of statistics.

description: Two-dimensional (2D) disordered superconductor (SC) in class D exhibits a disorder-induced quantum multicritical phenomenon among diffusive thermal metal (DTM), topological superconductor (TS), and conventional localized (AI) phases. To characterize the quantum tricritical point where these three phases meet, we carry out a two-loop renormalization group (RG) analysis for 2D Dirac fermion with random mass in terms of the $ε$-expansion in the spatial dimension $d=2-ε$. In 2D ($ε=0$), the random mass is marginally irrelevant around a clean-limit fixed point of the gapless Dirac fermion, while there exists an IR unstable fixed point at finite disorder strength that corresponds to the tricritical point. The critical exponent, dynamical exponent, and scaling dimension of the (uniform) mass term are evaluated around the tricritical point by the two-loop RG analysis. Using a mapping between an effective theory for the 2D random-mass Dirac fermion and the (1+1)-dimensional Gross-Neveu model, we further deduce the four-loop evaluation of the critical exponent, and the scaling dimension of the uniform mass around the tricritical point. Both the two-loop and four-loop results suggest that criticalities of a AI-DTM transition line as well as TS-DTM transition line are controlled by other saddle-point fixed point(s) at finite uniform mass.

description: During the campaign of 2015, the conservation works at the Roman baths – which started in 2014 – were completed. The large building is now in a stable state. Cleaning and qualifying the ruin’s environment provide visitors’ safety and help understanding the structure and its later modifications. Parts of some rooms are now accessible for the first time. Effectively, the three-month work was supervised by a mixed German-Turkish team of architects – a model which is recommended in Priene also for the next years restoration projects.

description: During excavation work for a new museum in Chimtou (ancient Simitthus)/ Tunesia a hoard of 1,648 late antique solidi was found weighing up to 7.3 kg. In the following years, Hans Roland Baldus (Kommission für Alte Geschichte und Epigraphik des DAI) and his Tunesian colleague Mustapha Khanoussi (Institut National du Patrimoine) studied this huge treasure by compiling a catalogue and trying to shed light on the question when this hoard was buried and why this happened. They also investigated the background of a number of very interesting coins and discussed the question what this hoard tells us about the circulation of gold coins in late antique North Africa. In the end of 2014 their research results were published in volume IV of the Simitthus series.
Using range data for object recognition in a robotics environment
Creators: name: Archibald, Colin
Publisher: name: University of British Columbia
Year: 2010

description: A new approach to object recognition for a robotics environment is presented. 2-D models enriched with 3-D information are constructed automatically from a range image. These 'view models' are used to recognize objects by matching them to models subsequently constructed from similar images. A segmentation method for extraction of planar surfaces from range images has been developed. View models are constructed as augmented surface adjacency graphs. A heuristic model matching method, is presented. Results indicate that object recognition in a constrained domain and environment can be achieved at a very high success rate using singlevview range images.

description: There are two elementary superconducting qubit types that derive directly from the quantum harmonic oscillator. In one the inductor is replaced by a nonlinear Josephson junction to realize the widely used charge qubits with a compact phase variable and a discrete charge wavefunction. In the other the junction is added in parallel, which gives rise to an extended phase variable, continuous wavefunctions and a rich energy level structure due to the loop topology. While the corresponding rf-SQUID Hamiltonian was introduced as a quadratic, quasi-1D potential approximation to describe the fluxonium qubit implemented with long Josephson junction arrays, in this work we implement it directly using a linear superinductor formed by a single uninterrupted aluminum wire. We present a large variety of qubits all stemming from the same circuit but with drastically different characteristic energy scales. This includes flux and fluxonium qubits but also the recently introduced quasi-charge qubit with strongly enhanced zero point phase fluctuations and a heavily suppressed flux dispersion. The use of a geometric inductor results in high precision of the inductive and capacitive energy as guaranteed by top-down lithography - a key ingredient for intrinsically protected superconducting qubits. The geometric fluxonium also exhibits a large magnetic dipole, which renders it an interesting new candidate for quantum sensing applications.

description: Fast sweep projection onto Feshbach molecules has been widely used as a probe of fermionic condensates. By determining the exact dynamics of a pair of atoms in time varying magnetic fields, we calculate the number of condensed and noncondensed molecules created after fast magnetic field sweeps from the BCS to the BEC side of the resonances in $^{40}$K and $^{6}$Li, for different sweep rates and a range of initial and final fields. We discuss the relation between the initial fermionic condensate fraction and the molecular condensate fraction measured after the sweep.

description: We present the theory of spontaneous symmetry breaking (SSB) of discrete time translations as recently realized in the space-time crystals of an atomic Bose-Einstein condensate. The non-equilibrium physics related to such a driven-dissipative system is discussed in both the Langevin as well as the Fokker-Planck formulation. We consider a semi-classical and a fully quantum approach, depending on the dissipation being either frequency independent or linearly dependent on frequency, respectively. For both cases, the Langevin equation and Fokker-Planck equation are derived, and the resulting equilibrium distribution is studied. We also study the time evolution of the space-time crystal and focus in particular on its formation and the associated dynamics of the spontaneous breaking of a Z2 symmetry out of the symmetry unbroken phase, i.e., the equilibrium Bose-Einstein condensate before the periodic drive is turned on. Finally, we compare our results with experiments and conclude that our theory provides a solid foundation for the observations.

description: The solar wind escapes from the solar corona and is accelerated, over a short distance, to its terminal velocity. The energy balance associated with this acceleration remains poorly understood. To quantify the global electrostatic contribution to the solar wind dynamics, we empirically estimate the ambipolar electric field ($\mathrm{E}_\parallel$) and potential ($Φ_\mathrm{r,\infty}$). We analyse electron velocity distribution functions (VDFs) measured in the near-Sun solar wind, between 20.3\,$R_S$ and 85.3\,$R_S$, by the Parker Solar Probe. We test the predictions of two different solar wind models. Close to the Sun, the VDFs exhibit a suprathermal electron deficit in the sunward, magnetic field aligned part of phase space. We argue that the sunward deficit is a remnant of the electron cutoff predicted by collisionless exospheric models (Lemaire & Sherer 1970, 1971, Jockers 1970). This cutoff energy is directly linked to $Φ_\mathrm{r,\infty}$. Competing effects of $\mathrm{E}_\parallel$ and Coulomb collisions in the solar wind are addressed by the Steady Electron Runaway Model (SERM) (Scudder 2019). In this model, electron phase space is separated into collisionally overdamped and underdamped regions. We assume that this boundary velocity at small pitch angles coincides with the strahl break-point energy, which allows us to calculate $\mathrm{E}_\parallel$. The obtained $Φ_\mathrm{r,\infty}$ and $\mathrm{E}_\parallel$ agree well with theoretical expectations. They decrease with radial distance as power law functions with indices $α_Φ= -0.66$ and $α_\mathrm{E} = -1.69$. We finally estimate the velocity gained by protons from electrostatic acceleration, which equals to 77\% calculated from the exospheric models, and to 44\% from the SERM model.

description: Abstract

The low performance of education office employees in the city of Tomohon Indonesia may be caused by the low motivation of employees in carrying out their main duties and functions. This study aims to test whether there is a positive and significant correlation of work motivation to work performance, whether there is a positive and significant correlation of the influence of supervision on work performance, and whether there is a positive and significant correlation of the effect of work motivation and supervision simultaneously on the work performance of employees of the Education Office in Tomohon City Indonesia. The method used in this study is a survey method with a questionnaire data collection tool arranged in the form of a Likert scale. The study respondents were 68 employees who were drawn by random sampling. Face-to-face data collection was conducted with the consent of all private respondents. The analysis used to test the research hypothesis is a simple regression and correlation analysis technique, as well as multiple correlations for three variables. The conclusions of this study are (1) work motivation has a positive effect on the work performance of Tomohon City Education Office employees, (2) Supervision has a positive effect on the work performance of Tomohon City Education Office employees, and (3) work motivation and supervision simultaneously have a positive effect on the work performance of Tomohon City Education Office employees. It is recommended: (1) need to build mutual commitment among employees and superiors and always develop the ability to achieve in order to improve work performance, (2) need to cultivate motivation at work by providing compensation in accordance with employee work results in the form of rewards, and (3) improve employee work performance by changing the mindset where work is a form of worship to improve work-based management skills.

description: Short-term reliability and robustness of 110 nm AlN/GaN HEMTs has been evaluated by means of off-state, semi-on state and on-state step stress tests on devices having different gate-drain distance, LGD. While breakdown voltages and critical voltages scale almost linearly with LGD, failure mode remains almost unchanged in all tested devices, and consists in an increase of gate leakage, accompanied by a positive shift of threshold voltage. In off-state, electroluminescence images detect the presence of localized leakage paths which may act as preferential paths for electron trapping. Degradation does not depend on dissipated power and is preliminary attributed to hot-electron trapping, enhanced by electric fields.

description: During the Formative period, the foundations for the first complex societies were laid in the Central Andes. The Paracas culture (800–200 BC) was the regional expression of the late Formative Period in southern Peru. While most research about the Paracas culture had focussed on grave offerings, especially ceramic and textiles, in this project we investigate the settlement patterns and socioeconomic structures of the Paracas culture. Our research in the highlands of the Palpa region has shown that the territory of the Paracas culture was much larger than previously thought and that sophisticated economic exchange systems had been established in order to take advantage of the diverse economy of a multitude of ecological regions in southern Peru.

description: Grain surface chemistry is key to the composition of protoplanetary disks around young stars. The temperature of grains depends on their size. We evaluate the impact of this temperature dependence on the disk chemistry. We model a moderately massive disk with 16 different grain sizes. We use POLARIS to calculate the dust grain temperatures and the local UV flux. We model the chemistry using the 3-phase astrochemical code NAUTILUS. Photoprocesses are handled using frequency-dependent cross-sections, and a new method to account for self and mutual shielding. The multi-grain model outputs are compared to those of single-grain size models (0.1 $μ$m), with two different assumptions for their equivalent temperature. We find that the Langmuir-Hinshelwood (LH) mechanism at equilibrium temperature is not efficient to form H$_2$ at 3-4 scale heights ($H$), and adopt a parametric fit to a stochastic method to model H$_2$ formation instead. We find the molecular layer composition (1-3 $H$) to depend on the amount of remaining H atoms. Differences in molecular surface densities between single and multi-grain models are mostly due to what occurs above 1.5 $H$. At 100 au, models with colder grains produce H$_2$O and CH$_4$ ices in the midplane, and warmer ones produce more CO$_2$ ices, both allowing efficient depletion of C and O as soon as CO sticks on grain surfaces. Complex organic molecules (COMs) production is enhanced by the presence of warmer grains in the multi-grain models. Using a single grain model mimicking grain growth and dust settling fails to reproduce the complexity of gas-grain chemistry. Chemical models with a single grain size are sensitive to the adopted grain temperature, and cannot account for all expected effects. A spatial spread of the snowlines is expected to result from the ranges in grain temperature. The amplitude of the effects will depend on the dust disk mass.

description: The linear and non-linear dynamic response to an oscillatory shear flow of giant wormlike micelles consisting of Pb-Peo block copolymers is studied by means of Fourier transform rheology. Experiments are performed in the vicinity of the isotropic-nematic phase transition concentration, where the location of isotropic-nematic phase transition lines is determined independently. Strong shear-thinning behaviour is observed due to critical slowing down of orientational diffusion as a result of the vicinity of the isotropic- nematic spinodal. This severe shear-thinning behaviour is shown to result in gradient shear banding. Time-resolved Small angle neutron scattering experiments are used to obtain insight in the microscopic phenomena that underly the observed rheological response. An equation of motion for the order-parameter tensor and an expression of the stress tensor in terms of the order-parameter tensor are used to interpret the experimental data, both in the linear and non-linear regime. Scaling of the dynamic behaviour of the orientational order parameter and the stress is found when critical slowing down due to the vicinity of the isotropic-nematic spinodal is accounted for.

description: n scalar-tensor theories of gravity with torsion, the gravitational field is described in terms of a symmetric metric tensor $g$, a metric-compatible connection $\nabla$ with torsion, and a scalar field $ϕ$. The main aim is to explore an interaction of a charged perfect fluid and a scalar field $ϕ$ in a background electromagnetic and gravitational field described by \{$g$, $\nabla$, $ϕ$\}. The interaction is based on an action functional $S_C$ of a charged perfect fluid that is invariant under global conformal rescalings. Using a variational principle, we obtain equations of motion for the charged perfect fluid. Moreover, we verify that these equations of motion are equivalent to the gauge identities obtained from the invariance of an action functional under spacetime dffeomorphisms and a local U(1) gauge group.

description: Aims: We aim to achieve high spatial resolution as well as high polarimetric sensitivity, using an earth-based 1m-class solar telescope, for the study of magnetic fine structure on the Sun. Methods: We use a setup with 3 high-speed, low-noise cameras to construct datasets with interleaved polarimetric states, particularly suitable for Multi-Object Multi-Frame Blind Deconvolution image restorations. We discuss the polarimetric calibration routine as well as various potential sources of error in the results. Results: We obtained near diffraction limited images, with a noise level of approximately 10^(-3) I(cont). We confirm that dark-cores have a weaker magnetic field and at a lower inclination angle with respect to the solar surface than the edges of the penumbral filament. We show that the magnetic field strength in faculae-striations is significantly lower than in other nearby parts of the faculae.

description: The Neolithic site of eh-Sayyeh in Northern Jordan covers more than 10 ha and is therefore designated as a mega site. Main settlement periods are attested for the 8th and 6th mill. calBC. During the investigations carried out in 2015 a completely intact oval building with stone cover was exposed, which showed no archaeological material inside. Typologically it reminds of late Neolithic graves. Therefore, this structure might hypothetically be interpreted as a grave which was never used.

description: In recent years, phosphorus monoxide (PO) -- an important molecule for prebiotic chemistry -- has been detected in star-forming regions and in the comet 67P/Churyumov-Gerasimenko. These studies have revealed that, in the interstellar medium, PO is systematically the most abundant P-bearing species, with abundances that are $\sim$1-3 times greater than those derived for phosphorus nitride (PN), the second most abundant P-containing molecule. The reason why PO is more abundant than PN remains still unclear. Experimental studies with phosphorus in the gas phase are not available, probably because of the difficulties in dealing with its compounds. Therefore, the reactivity of atomic phosphorus needs to be investigated using reliable computational tools. To this end, state-of-the-art quantum-chemical computations have been employed to evaluate accurate reaction rates and branching ratios for the P + OH $\rightarrow$ PO + H and P + H$_2$O $\rightarrow$ PO + H$_2$ reactions in the framework of a master equation approach based on ab-initio transition state theory. The hypothesis that OH and H${_2}$O can be potential oxidizing agents of atomic phosphorus is based on the ubiquitous presence of H${_2}$O in the ISM. Its destruction then produces OH, which is another very abundant species. While the reaction of atomic phosphorus in its gound state with water is not a relevant source of PO because of emerged energy barriers, the P + OH reaction represents an important formation route of PO in the interstellar medium. Our kinetic results show that this reaction follow an Arrhenius behavior, and thus its rate coefficients alpha=2.28$\times$10$^{-10}$ cm${^3}$ molecule$^{-1}$ s$^{-1}$, beta=0.16 and gamma=0.37 K increase by increasing the temperature.

description: Based on 2MASS J and Ks photometry for the open star clusters NGC 2383, NGC 2384,Pismis 6, Pismis 8 and using color magnitude diagrams with isochrones fit, we found an age of $\log ({age})$ = 8.3 (200 $\pm$ 6 Myr) for NGC 2383 and $\log ({age})$ = 6.9 (8 $\pm$ 6 Myr) for NGC 2384. For Pismis 6 and Pismis 8 we adopted a range of $\log ({age})$ = 6 - 7 (1 - 10 Myr). Because they similar ages, Pismis 6 and Pismis 8 may have been formed in the same Giant Molecular Cloud, and we concluded they are a good candidate for a binary system. In the case of NGC 2383 and NGC 2384, because the big age difference found we conclude that most probably they are born in different environments and as well are not physically connected.

description: In superconductors, the motion of vortices introduces unwanted dissipation that is disruptive to applications. Fortunately, material defects can immobilize vortices, acting as vortex pinning centers, which engenders dramatic improvements in superconductor material properties and device operation. This has motivated decades of research into developing methods of tailoring the disorder landscape in superconductors to increase the strength of vortex pinning. Yet efficacious materials engineering still alludes us. The electromagnetic properties of real (disordered) superconducting materials cannot yet be reliably predicted, such that designing superconductors for applications remains a largely inefficient process of trial and error. This is ultimately due to large gaps in our knowledge of vortex dynamics: the field is challenged by the extremely complex interplay between vortex elasticity, vortex-vortex interactions, and material disorder. In this Perspective, we review obstacles and recent successes in understanding and controlling vortex dynamics in superconducting materials and devices. We further identify major open questions and discuss opportunities for transformative research in the field. This includes improving our understanding of vortex creep, determining and reaching the ceiling for the critical current, advanced microscopy to garner accurate structure-property relationships, frontiers in predictive simulations and the benefits of artificial intelligence, as well as controlling and exploiting vortices in quantum information applications.

description: The most famous Neronian buildings are undoubtedly his palace complexes. All these efforts to create a “Neronian” architecture culminated in the Domus Aurea. Although these reports give a different impression, the Domus Aurea building project was in fact never quite finished. Still, it is plausible that an overall plan or a model of the Domus Aurea project existed, or that the courtiers gained a good impression of the intended look of the complex from the princeps’ comments about it. Because of later building activity, only a few of those structures in the area of the Domus Aurea, which “seemed like cities,” remain. Most of what has survived belonged to the part of the Domus Aurea which was located on the side of the Oppian Hill, believed to have been the main building of the complex. At present, however, the exact dimension of the building complex and the shape of its layout are not yet known.
A deep dive into the $2g+h$ resonance: separatrices, manifolds and phase space structure of navigation satellites

description: Despite extended past studies, several questions regarding the resonant structure of the medium-Earth orbit (MEO) region remain hitherto unanswered. This work describes in depth the effects of the $2g+h$ lunisolar resonance. In particular, (i) we compute the correct forms of the separatrices of the resonance in the inclination-eccentricity space for fixed semi-major axis. This allows to compute the change in the width of the $2g+h$ resonance as the altitude increases. (ii) We discuss the crucial role played by the value of the inclination of the Laplace plane, $i_{L}$. Since $i_L$ is comparable to the resonance's separatrix width, the parametrization of all resonance bifurcations has to be done in terms of the proper inclination $i_{p}$, instead of the mean one. (iii) The subset of circular orbits constitutes an invariant subspace embedded in the full phase space, the center manifold $\mathcal{C}$. Using $i_p$ as a label, we compute its range of values for which $\mathcal{C}$ becomes a normally hyperbolic invariant manifold (NHIM). The structure of invariant tori in $\mathcal{C}$ allows to explain the role of the initial phase $h$ noticed in several works. (iv) Through Fast Lyapunov Indicator (FLI) cartography, we portray the stable and unstable manifolds of the NHIM as the altitude increases. Manifold oscillations dominate in phase space between $a=24,000$ km and $a=30,000$ km as a result of the sweeping of the $2g+h$ resonance by the $h-Ω_{\rm{Moon}}$ and $2h-Ω_{\rm{Moon}}$ resonances. The noticeable effects of the latter are explained as a consequence of the relative inclination of the Moon's orbit with respect to the ecliptic. The role of the phases $(h,Ω_{\rm{Moon}})$ in the structures observed in the FLI maps is also clarified. Finally,(v) we discuss how the understanding of the manifold dynamics could inspire end-of-life disposal strategies.

description: The first known basilica in the area was the Basilica Sempronia erected in 170 BC by the censor Titus Sempronius Gracchus behind the tabernae veteres. During the reign of Caesar, the building was named Basilica Iulia and got its final architectural setting. Two aisles which were formed by rows of pillars surrounded the central court on all sides. Near the northwestern corner of the building next to the lacus Servilius the so called arch of Tiberius was erected in Augustean times and probably dedicated by Tiberius. In its interior, the basilica presented itself as a luxurious utility building which was most of all equipped for mercantile and monetary purposes. As at so many Roman basilicas, probably also at the Basilica Iulia civil actions like financial tribunals took place.

description: We derive constraints on the statistics of the charge transfer between two conductors in the model of arbitrary time-dependent instant scattering of non-interacting fermions at zero temperature. The constraints are formulated in terms of analytic properties of the generating function: its zeroes must lie on the negative real axis. This result generalizes existing studies for scattering by a time-independent scatterer under time-dependent bias voltage.

description: The J,K = 1,0-0,0 rotational transition of phosphine (PH3) at 267 GHz has been tentatively identified with a T_MB = 40 mK spectral line observed with the IRAM 30-m telescope in the C-star envelope IRC+10216. A radiative transfer model has been used to fit the observed line profile. The derived PH3 abundance relative to H2 is 6 x 10^(-9), although it may have a large uncertainty due to the lack of knowledge about the spatial distribution of this species. If our identification is correct, it implies that PH3 has a similar abundance to that reported for HCP in this source, and that these two molecules (HCP and PH3) together take up about 5 % of phosphorus in IRC+10216. The abundance of PH3, as that of other hydrides in this source, is not well explained by conventional gas phase LTE and non-LTE chemical models, and may imply formation on grain surfaces.
