description: We present a new distance estimation method for dust-continuum-identified molecular cloud clumps. Recent (sub-)millimeter Galactic plane surveys have cataloged tens of thousands of these objects, but detailed study of their physical properties requires robust distance determinations. We derive Bayesian distance probability density functions (DPDFs) for 770 objects from the Bolocam Galactic Plane Survey in the longitude range 7.5 < l < 65. The DPDF formalism is based on kinematic distances, and uses external data sets to place prior distance probabilities to resolve the kinematic distance ambiguity (KDA) for objects in the inner Galaxy. We present priors related to the mid-infrared absorption of dust in dense molecular regions and the Galactic distribution of molecular gas. By assuming a numerical model of Galactic mid-infrared emission and simple radiative transfer, we match the morphology of millimeter thermal dust emission with mid-infrared absorption to compute a prior DPDF for distance discrimination. Selecting objects first from (sub-)millimeter source catalogs avoids a bias towards the darkest infrared dark clouds (IRDCs) and extends the range of heliocentric distance and contrast range probed by mid-infrared extinction. We derive well-constrained KDA resolutions for 618 molecular cloud clumps, with approximately 15% placed at or beyond the tangent distance. Objects sufficiently dark to be cataloged as IRDCs are generally placed at the near kinematic distance. Distance comparisons with Galactic Ring Survey KDA resolutions yield a 92% agreement, and a Galactic face-on view reveals sections of the Sagittarius and Scutum-Centaurus Arms. This KDA-resolution method for large catalogs of sources through the combination of (sub-)millimeter and mid-infrared observations of molecular cloud clumps is generally applicable to other dust-continuum Galactic plane surveys.

description: The transition between the gas-, supercritical-, and liquid-phase behaviour is a fascinating topic which still lacks molecular-level understanding. Recent ultrafast two-dimensional infrared spectroscopy experiments suggested that the vibrational spectroscopy of N$_2$O embedded in xenon and SF$_6$ as solvents provides an avenue to characterize the transitions between different phases as the concentration (or density) of the solvent increases. The present work demonstrates that classical molecular dynamics simulations together with accurate interaction potentials allows to (semi-)quantitatively describe the transition in rotational vibrational infrared spectra from the P-/R-branch lineshape for the stretch vibrations of N$_2$O at low solvent densities to the Q-branch-like lineshapes at high densities. The results are interpreted within the classical theory of rigid-body rotation in more/less constraining environments at high/low solvent densities or based on phenomenological models for the orientational relaxation of rotational motion. It is concluded that classical MD simulations provide a powerful approach to characterize and interpret the ultrafast motion of solutes in low to high density solvents at a molecular level.

description: İt is necessary to construct equations of state that qualitatively and quantitatively accurately reflect the behavior of the thermodynamic surface in the considered range of parameters, in order to compile tables of the thermodynamic properties of liquids. A sufficient amount of highprecision experimental data on the P-V-T dependence is necessary to constructing such equations. Most of the equations are not suitable for extrapolation, they are valid in limited areas of state parameters. An equation of state with three coefficients is proposed to describe the P--T dependence of liquid hydrocarbons of various molecular structures (benzene, n-octane, isooctane, octene-1).

description: We report the radio and high-energy properties of a new outburst from the radio-loud magnetar 1E 1547.0$-$5408. Following the detection of a short burst from the source with Swift-BAT on 2022 April 7, observations by NICER detected an increased flux peaking at $(6.0 \pm 0.4) \times 10^{-11}$ erg s$^{-1}$ cm$^{-2}$ in the soft X-ray band, falling to the baseline level of $1.7\times10^{-11}$ erg s$^{-1}$ cm$^{-2}$ over a 17-day period. Joint spectroscopic measurements by NICER and NuSTAR indicated no change in the hard non-thermal tail despite the prominent increase in soft X-rays. Observations at radio wavelengths with Murriyang, the 64-m Parkes radio telescope, revealed that the persistent radio emission from the magnetar disappeared at least 22 days prior to the initial Swift-BAT detection and was re-detected two weeks later. Such behavior is unprecedented in a radio-loud magnetar, and may point to an unnoticed slow rise in the high-energy activity prior to the detected short-bursts. Finally, our combined radio and X-ray timing revealed the outburst coincided with a spin-up glitch, where the spin-frequency and spin-down rate increased by $0.2 \pm 0.1$ $μ$Hz and $(-2.4 \pm 0.1) \times 10^{-12}$ s$^{-2}$ respectively. A linear increase in spin-down rate of $(-2.0 \pm 0.1) \times 10^{-19}$ s$^{-3}$ was also observed over 147 d of post-outburst timing. Our results suggest that the outburst may have been associated with a reconfiguration of the quasi-polar field lines, likely signalling a changing twist, accompanied by spatially broader heating of the surface and a brief quenching of the radio signal, yet without any measurable impact on the hard X-ray properties.

description: Modern society is developing in the direction of redistributing capital flows as part of the global trend towards decarbonization, developing environmental standards and increasing the social responsibility of business and the economy as a whole. Investors are actively increasing their investments in companies that support sustainable development strategies, as changes related to ESG principles are taking place around the world and are seen by most participants as a promising opportunity for development and revenue generation. The current challenge facing society and business is to study the ESG agenda, implement it into operations and develop appropriate recommendations to promote ESG principles to improve the environment and wellbeing of the global community. In order to address inequality and stimulate economic growth, the UN adopted the 2030 Agenda for Sustainable Development in 2015 and launched a plan to ensure sustainability for present and future generations, reduce poverty and improve the lives of people around the world. Governments and business communities in various countries are realizing the adverse impacts of climate change, which affects the well-being and economic status of the nation, and building a more sustainable global economy contributes to reducing greenhouse gas emissions that cause climate change. Priority tasks of the global community are multifunctionality and demand for the development and implementation of specific mechanisms for achieving sustainable development goals based on the integrated solution of economic, environmental and social problems and harmonization of long-term interests of the state, business and civil society.

description: Metallic Bi2Te3 crystalline sheets with the room-temperature resistivity of above 10 mΩ cm were prepared and their magnetoresistive transport was measured in a field of up to 9 Tesla. The Shubnikov de Haas oscillations were identified from the secondly-derived magnetoresistance curves. While changing the angle between the field and normal axis of the sheets, we find that the oscillation periods present a cosine dependence on the angle. This indicates a two-dimensional transport due to the surface state. The work reveals a resolvable surface contribution to the overall conduction even in a metallic topological insulator.

description: The problem of determining the probability of timely elimination of critical failures under conditions of incomplete data represented by small samples of hardware dwell time in failure state and critical hardware time is considered. This probability is the probability of stochastic dominance of the critical time of the hardware over the time of the hardware in the state of failure, i.e. the probability that the random time of the hardware in the state of failure is less than the critical time of the hardware. Critical time is the time during which the elimination of the occurred failures does not lead to the occurrence of an unrecoverable failure of the object or to a significant reduction in the efficiency of its functioning. The problem of determining the probability of timely elimination of critical failures is formulated as a problem of finding guaranteed (lower and upper) probability estimates on the set of available initial data, represented by small samples of the time of stay of the equipment in the state of failure and critical time of the equipment. The guaranteed estimates of the probability of timely elimination of critical failures are found using the results of solving the problem of Markov moments.
Radiative feedback from protoplanets in self-gravitating protoplanetary discs

description: It is well known that massive protoplanetary disc are gravitationally unstable beyond tens of AU from their parent star. The eventual fate of the self-gravitating gas clumps born in the disc is currently not understood, although the range of uncertainty is well known. If clumps migrate inward rapidly, they are tidally disrupted, which may leave behind giant or terrestrial like planets. On the other hand, if clumps migrate less rapidly, they tend to accrete gas, becoming proto brown dwarfs or low mass companions to the parent star. Here we argue that radiative feedback of contracting clumps (protoplanets) on their discs is an important effect that has been overlooked in previous calculations. We show analytically that temperature in clump's vicinity may be high enough to support a quasi-static atmosphere if the clump mass is below a critical value, $M_{\rm cr} \sim 6$ Jupiter masses ($M_J$). This may arrest further gas accretion onto the clump and thus promote formation of planets rather than low mass companions. We use numerical simulations to evaluate these analytical conclusions by studying migration and accretion of gas clumps as a function of their initial mass, $M_i$. Simulations neglecting the radiative preheating effect show that gas clumps with mass less than $\sim 2 M_J$ migrate inward rapidly; more massive clumps result in low mass companions. In contrast, simulations that include radiative preheating from the clump show that clumps as massive as $8 M_J$ migrate inward rapidly and end up tidally disrupted in the inner disc. We conclude that, with other parameters being equal, previous simulations neglecting radiative feedback from self-gravitating clumps over-estimated the population of brown dwarfs and low mass stellar companions and under-estimated the population of planets.

description: Evaluating international technical assistance projects usually calls for assessing the efficiency and effectiveness of planned indicators. As climatic uncertainty and risk increase, there is a need to improve approaches to assessing the activities of such projects. Using the example of a project to adapt dryland dehkan households, cooperatives, and farms in the Aral Sea region (the Republic of Karakarpakstan in Uzbekistan) to climate change, this research methodically substantiates a set of indicators to assess the long-term effectiveness of adaptation measures. With regard to humanitarian support measures (which are strengthening the hydrometeorological monitoring network, creating early warning systems, raising public awareness about various climate threats and possibilities to reduce their negative consequences, and reclaiming the dried-up Aral Sea bottom to reduce dustiness) that pursue non-economic goals, an assessment was made against previously established project performance indicators. With regard to ensuring the viability of dehkan households, cooperatives and farms over the long term, this research proves the need in evaluating the effectiveness of agronomic, water-saving, and landscape adaptation measures as a combination of private benefits (economic efficiency) and public goods (social and environmental efficiency). These evaluation indicators will help identify the most promising, effective and efficient practices to replicate in future projects.

description: We study the bivariate size-luminosity distribution of Lyman Break Galaxies (LBGs) selected at redshifts around 4 and 5 in GOODS and the HUDF fields. We model the size-luminosity distribution as a combination of log-normal distribution (in size) and Schechter function (in luminosity), therefore it enables a more detailed study of the selection effects. We perform extensive simulations to quantify the dropout-selection completenesses and measurement biases and uncertainties in two-dimensional size and magnitude bins, and transform the theoretical size-luminosity distribution to the expected distribution for the observed data. Using maximum-likelihood estimator (MLE), we find that the Schechter function parameters for B-dropouts are α=-1.68^{+0.068}_{-0.095}, M*=-20.60^{+0.13}_{-0.17}, and ϕ*=1.79^{+0.32}_{-0.52} x 10^{-3} Mpc^{-3}. The log-normal size distribution is characterized by the peak R_0=1.34^{+0.099}_{-0.108} kpc at M_{1500}=-21 mag, width σ_{\lnR}=0.83^{+0.046}_{-0.044}, and the slope of the size-luminosity (RL) relation β=0.22^{+0.058}_{-0.056}. Similarly, for V-dropouts we find α=-1.74^{+0.15}_{-0.20}, M*=-20.53^{+0.24}_{-0.27}, ϕ*=1.55^{+0.62}_{-0.77} x 10^{-3} Mpc}^{-3}, R_0=1.19^{+0.21}_{-0.16} kpc, σ_{\lnR}=0.90^{+0.15}_{-0.065}, and β=0.25^{+0.15}_{-0.14}. The Schechter function parameters are consistent with the values in the literature, while the size distributions are wider than expected from the angular momentum distribution of the underlying dark matter halos. The slope of the size-luminosity (RL) relation is similar to those found for local disk galaxies, but considerably shallower than local early-type galaxies.

description: Mechanical systems, the calculation of vibrations of which is the content of many practical problems, are mostly complex elastic systems. At the same time, many structural elements can be represented by a combination of different rods; therefore, in various fields of modern technology, it is necessary to solve the problems of oscillations of complex rod systems, including those in a collision with an obstacle. The relevance of the problem of calculating the vibrations of complex rod systems is due to the practical need to improve the technical characteristics of the designed machines and mechanisms and ensure their functioning under ever wider ranges of operational impacts, as well as to reduce the material consumption of machines and structures. To fully determine the strains and stresses that occur at any point in the system during vibrations, it is necessary to know the displacements at these points. This leads to the need to consider systems with an infinite number of degrees of freedom.

Final version of advanced autonomous functionalities for ground robots and crawlers
Creators: name: PILOTING Project
Publisher: name: Zenodo
Year: 2023

description: The main purpose of this document is to present the final version of the algorithms developed with respect to dexterous manipulation, advanced perception and intelligent navigation for autonomous inspection and maintenance for ground robots and crawlers. Moreover, the document describes how the final solutions have been improved from the beta versions described in D5.2 based on the experience from the initial test campaign. These functionalities are targeting firstly refineries with inspection both inside tanks and vessels as well as outside including manipulation of valves. Secondly, autonomous navigation in tunnels for ground vehicles is addressed. A common challenge in these scenarios is the lack of satellite coverage, which makes it necessary to find solutions for localization that do not rely on GNSS to enable autonomous functionality. Therefore, functionalities for perception based on sensors such as LiDARs, cameras and IMUs have been developed to implement the autonomous functions that support the inspection robots in the PILOTING platform. This deliverable is the direct outcome of the work performed within tasks T5.2 (“Dexterous manipulation from ground vehicles”) and T5.4 (“Perception and intelligent navigation for ground robots and crawlers”).

description: Context: We have analysed Herschel-PACS spectra of 32 circumstellar disks around Herbig Ae/Be and T-Tauri stars obtained within the Herschel key programme DIGIT. In this paper we focus on the 69mu emission band of the crystalline silicate forsterite. Aims: This work provides an overview of the 69mu forsterite bands in the DIGIT sample. We aim to derive the temperature and composition of the forsterite grains. With this information, constraints can be placed on the spatial distribution of the forsterite in the disk and its formation history. Methods: Position and shape of the 69mu band are used to derive the temperature and composition of the dust by comparison to laboratory spectra of that band. We combine our data with existing Spitzer IRS spectra to compare the presence and strength of the 69mu band to the forsterite bands at shorter wavelengths. Results: A total of 32 sources have been observed, 8 of them show a 69mu emission band that can be attributed to forsterite. With the exception of the T-Tauri star AS205, all of the detections are for disks associated with Herbig Ae/Be stars. Most of the forsterite grains that give rise to the 69mu bands are warm (~100-200 K) and iron-poor (less than ~2% iron). Only AB-Aur requires approximately 3-4% of iron. Conclusions: Our findings support the hypothesis that the forsterite grains form through an equilibrium condensation process at high temperatures. The connection between the strength of the 69 and 33mu bands shows that at least part of the emission in these bands originates from the same dust grains. Further, any model that explains the PACS and the Spitzer IRS observations must take the effects of a wavelength dependent optical depth into account. We find indications of a correlation of the detection rate of the 69mu band with the spectral type of the host stars. However, our sample is too small to obtain a definitive result.

description: We used STM to study the tunneling spectra of FeSe0.3Te0.7 films with two orientations of ab-planes and the connection ramp between them. We have discovered that, using pulse laser deposition (PLD) method, the a- and b-axis of the FeSe0.3Te0.7 film deposited on Ar-ion-milled Magnesium Oxide (MgO) substrate are rotated 45 degree with respect to those of MgO, while the a- and b-axis of the film grown on pristine MgO substrate are parallel to those of MgO. With photolithography and this technique, we can prepare FeSe0.3Te0.7 film with two kinds of orientations on the same MgO substrate, and the connection between them forms a ramp at an angle about 25 degree to the substrate plane. In the planar region with either 0 degree or 45 degree orientation, we have observed tunneling spectra with a superconducting gap about 5 meV and 1.78 meV respectively. However, a much larger gap about 18 meV has been observed in the ramp region. Furthermore, we have also observed a small zero-bias conductance peak (ZBCP) inside the large gap at T = 4.3K. The ZBCP becomes smaller and disappear with increasing temperature to 7 K. The possible causes of such large gap and the ZBCP will be discussed.

description: Answer Set Programming (ASP) is a truly-declarative programming paradigm proposed in the area of non-monotonic reasoning and logic programming, that has been recently employed in many applications. The development of efficient ASP systems is, thus, crucial. Having in mind the task of improving the solving methods for ASP, there are two usual ways to reach this goal: $(i)$ extending state-of-the-art techniques and ASP solvers, or $(ii)$ designing a new ASP solver from scratch. An alternative to these trends is to build on top of state-of-the-art solvers, and to apply machine learning techniques for choosing automatically the "best" available solver on a per-instance basis. In this paper we pursue this latter direction. We first define a set of cheap-to-compute syntactic features that characterize several aspects of ASP programs. Then, we apply classification methods that, given the features of the instances in a {\sl training} set and the solvers' performance on these instances, inductively learn algorithm selection strategies to be applied to a {\sl test} set. We report the results of a number of experiments considering solvers and different training and test sets of instances taken from the ones submitted to the "System Track" of the 3rd ASP Competition. Our analysis shows that, by applying machine learning techniques to ASP solving, it is possible to obtain very robust performance: our approach can solve more instances compared with any solver that entered the 3rd ASP Competition.

description: We report results of infrared imaging and spectroscopic observations of the SN 1006 remnant, carried out with the Spitzer Space Telescope. The 24 micron image from MIPS clearly shows faint filamentary emission along the northwest rim of the remnant shell, nearly coincident with the Balmer filaments that delineate the present position of the expanding shock. The 24 micron emission traces the Balmer filaments almost perfectly, but lies a few arcsec within, indicating an origin in interstellar dust heated by the shock. Subsequent decline in the IR behind the shock is presumably due largely to grain destruction through sputtering. The emission drops far more rapidly than current models predict, however, even for a higher proportion of small grains than would be found closer to the Galactic plane. The rapid drop may result in part from a grain density that has always been lower -- a relic effect from an earlier epoch when the shock was encountering a lower density -- but higher grain destruction rates still seem to be required. Spectra from three positions along the NW filament from the IRS instrument all show only a featureless continuum, consistent with thermal emission from warm dust. The dust-to-gas mass ratio in the pre-shock interstellar medium is lower than that expected for the Galactic ISM -- as has also been observed in the analysis of IR emission from other SNRs but whose cause remains unclear. As with other SN Ia remnants, SN 1006 shows no evidence for dust grain formation in the supernova ejecta.

description: As a result of the analysis, it was concluded that the existing fiber-optic sensors are mainly used to detect the place of unauthorized access. For this purpose, a fiber-optic sensor has been developed using G 655 optical fiber with the highest susceptibility to macrobending, which makes it possible to determine not only the fact of unauthorized access, but also the parameters of the penetrating object, namely its mass, to increase the measurement range of the attenuation of the branched signal of optical radiation due to amplification of this signal and the measurement limit of the body weight of the object of unauthorized access due to the choice of the spring stiffness coefficient. Experimental studies have been carried out to determine the susceptibility of various types of optical fiber to macrobending, the dependence of the attenuation of the optical radiation signal on the macrobending radius, the length of the macrobending arc, and the mass of the unauthorized access object.

description: Discussion threads form a central part of the experience on many Web sites, including social networking sites such as Facebook and Google Plus and knowledge creation sites such as Wikipedia. To help users manage the challenge of allocating their attention among the discussions that are relevant to them, there has been a growing need for the algorithmic curation of on-line conversations --- the development of automated methods to select a subset of discussions to present to a user. Here we consider two key sub-problems inherent in conversational curation: length prediction --- predicting the number of comments a discussion thread will receive --- and the novel task of re-entry prediction --- predicting whether a user who has participated in a thread will later contribute another comment to it. The first of these sub-problems arises in estimating how interesting a thread is, in the sense of generating a lot of conversation; the second can help determine whether users should be kept notified of the progress of a thread to which they have already contributed. We develop and evaluate a range of approaches for these tasks, based on an analysis of the network structure and arrival pattern among the participants, as well as a novel dichotomy in the structure of long threads. We find that for both tasks, learning-based approaches using these sources of information yield improvements for all the performance metrics we used.

description: The main goal of geodynamic analysis is to learn to perceive sedimentary basins as integral natural objects, to determine their genesis, structure and stages of evolution, classification of sedimentary basins and forecast of their oil and gas potential. It is well known that the changes that occur in the earth's crust are mainly the result of subcrustal processes and adjacent plate interaction. The type of the Earth's crust underlying the sedimentary basin determines the physical basis, stability, tectonic restructuring and sedimentation conditions throughout the evolution of the basin. Geodynamic conditions of sedimentary cover formation in the region under consideration were studied on the basis of the principles of tectonic formation of the Caspian basin and the adjacent area, developed by Azerbaijani and foreign scientists (A.A. AliZade, H.B. Yusifzade, A.A. Narimanov, M.M. Veliyev, A.D. Aliyev; B.E. Khain, A.V., Peyveh and many others). It is proved that this region is a complicated structural complex consisting of a system of island arcs, rift structures with a changing contour of the foot of the continental slope, underwater cordillera, marginal seas, deflections and uplifts. On the structural map constructed from the bottom of the sediments of the Productive strata (Lower Pliocene), in contrast to the maps of previous years, the axial lines of the deflection are shifted to the marginal parts of neighboring tectonic blocks. All this determines new scientific directions of oil and gas exploration in the Caspian basin.
