description: Hierarchical data representations in the context of classi cation and data clustering were put forward during the fties. Recently, hierarchical image representations have gained renewed interest for segmentation purposes. In this paper, we briefly survey fundamental results on hierarchical clustering and then detail recent paradigms developed for the hierarchical representation of images in the framework of mathematical morphology: constrained connectivity and ultrametric watersheds. Constrained connectivity can be viewed as a way to constrain an initial hierarchy in such a way that a set of desired constraints are satis ed. The framework of ultrametric watersheds provides a generic scheme for computing any hierarchical connected clustering, in particular when such a hierarchy is constrained. The suitability of this framework for solving practical problems is illustrated with applications in remote sensing.

description: This study aims to: (1) determine and analyze internal environmental factors that become strengths and weaknesses, (2) determine and analyze the external environmental factors that become opportunities and threats and (3) formulate strategies to strengthen the group. Research method used in this study is qualitativedescriptive analytic method. This study used the survey technique using a list of questions included in the questionnaire and distributed to the participants. The study found that: (1) internal strategic factors that become the strengths of Citra Mulya farmer group respectively include group dynamics, farmer group management, the level of motivation, and the operation of savings and loans. The group weaknesses comprise relatively narrow land tenure and acreage, low levels of human resources, lack of infrastructure, lack of mental effort (2) external strategic factors that become the group’s opportunities respectively include the availability of bank credit assistance, the existence of Rural Agribusiness Development or Pengembangan Usaha Agribisnis Pedesaan (PUAP) program, support from regional technical implementation unit – agency for agricultural, fishery and forestry or Unit Pelaksana Teknis-Balai Penyuluhan Pertanian, Perikanan dan Kehutanan (UPT- BP3K) at District Suranenggala, educational institutions and village government, and market opportunities in agriculture. Factors that become threats faced by the group are among others less optimal cross-sector coordination level, delays in the transfer of technology, the pest attack, uncertain climatic conditions and price fluctuations and (3) results of the internal and external analysis show that the position of the Citra Mulya farmer group is in quadrant I and the most appropriate general strategy is aggressive strategy.

description: Cette recherche est centrée sur le travail censorial d'un auteur libertin du XVIIIe siècle, Claude-Prosper Jolyot de Crébillon. Il sera question d'examiner comment les identités d'apparence contradictoires d'auteur et de censeur ont pu coexister chez lui. En sa qualité de censeur, Crébillon s'avère impartial et solidaire envers les gens de lettres. D'autant plus, il endosse un rôle de mentor envers les jeunes auteurs. D'un point de vue méthodologique, cette recherche fait appel à des connaissances de champs variés. Elle s'appuie tant sur des méthodologies historiques que littéraires, dont l'histoire culturelle, l'histoire des sociabilités et la sociologie de la littérature. En utilisant Crébillon à titre d'exemple, on peut nuancer davantage le travail des censeurs d'Ancien Régime et leur rapport avec le monde littéraire. Cette recherche a comme objectif de mettre en lumière la souplesse dont les censeurs ont pu faire preuve et la complicité qui a pu se développer entre eux et les auteurs.

description: Semiclassical black holes emit radiation called Hawking radiation. Such radiation, as seen by an asymptotic observer far outside the black hole, differs from original radiation near the horizon of the black hole by a redshift factor and the so-called "greybody factor". In this paper, we concentrate on the greybody factor-various bounds for the greybody factors of non-rotating black holes are obtained, concentrating on charged Reissner-Nordstrom and Reissner-Nordstrom-de Sitter black holes. These bounds can be derived by using a 2x2 transfer matrix formalism. It is found that the charges of black holes act as efficient barriers. Furthermore, adding extra dimensions to spacetime can shield Hawking radiation. Finally, the cosmological constant can increase the emission rate of Hawking radiation.

title: A Bridge and Engine Room Staffing and Scheduling Model for Robust Mission Accomplishment in the Littoral Combat Ships
Creators: name: Cordle, John P.
Publisher: name: Old Dominion University Libraries

description: The Navy’s Littoral Combat Ships were designed to be relatively small surface vessels for operations near a littoral shore theater. These ships were envisioned to be highly automated, networked, agile, stealthy surface combatants capable of defeating anti-access and asymmetric threats in the littorals with minimum manpower. To date, however, some of these ships have experienced significant engineering and propulsion plant failures that impacted mission accomplishment and were attributable, at least in part, to under staffing and over scheduling the human component of the automation-human operational environment. The critical human components on the Littoral Combat Ship are bridge and engine room staffing. Since the engineering plant has been the source of most major failures to date, this project sought to develop an engine room staffing and scheduling model for the Littoral Combat Ship class given a stated set of minimum mission objectives when operating under normal conditions – called “Condition III Underway Steaming”, which is used as the basis for official Navy manning calculations, and to provide recommendations for improved automation-human modeling. A survey of the crew of several LCS ships was conducted and the results were analyzed using exploratory data analysis and multiple joint correspondence analysis. Results of the survey analysis were applied to the design of a joint physical-cognitive-automation workflow analysis of critical procedures and failure modes as they map to four dimensions: fatigue, watch and maintenance tasking, and automation-human interface. Workflow analysis results were then simulated in an IMPRINT model of a typical watch period, and the results were evaluated against the four dimensions of the survey. The project validated that the four dimensions analyzed are indeed worthy of consideration in manpower models, and that IMPRINT has the potential, with a few modifications, to model joint physical-cognitive-automation workflows as an improvement to the current manpower-only models used in Navy ship design by accounting for human factors.

description: The Magellanic Cloud System (MCS) interacts via tidal and drag forces with the Milky Way galaxy. Using the Parkes Galactic All-Sky Survey (GASS) of atomic hydrogen we explore the role of drag on the evolution of the so-called Leading Arm (LA). We present a new image recognition algorithm that allows us to differentiate features within a 3-D data cube (longitude, latitude, radial velocity) and to parameterize individual coherent structures. We compiled an HI object catalog of LA objects within an area of 70 degr x 85 degr (1.6 sr) of the LA region. This catalog comprises information of location, column density, line width, shape and asymmetries of the individual LA objects above the 4-sigma threshold of Delta T_b simeq 200 mK. We present evidence of a fourth arm segment (LA4). For all LA objects we find an inverse correlation of velocities v_GSR in Galactic Standard of Rest frame with Magellanic longitude. High-mass objects tend to have higher radial velocities than low-mass ones. About 1/4 of all LA objects can be characterized as head-tail (HT) structures. Using image recognition with objective criteria, it is feasible to isolate most of LA emission from the diffuse Milky Way HI gas. Some blended gas components (we estimate 5%) escape detection, but we find a total gas content of the LA that is about 50% higher than previously assumed. These methods allow the deceleration of the LA clouds to be traced towards the Milky Way disk by drag forces. The derived velocity gradient strongly supports the assumption that the whole LA originates entirely in the Large Magellanic Cloud (LMC). LA4 is observed opposite to LA1, and we propose that both arms are related, spanning about 52kpc in space. HT structures trace drag forces even at tens of kpc altitudes above the Milky Way disk.

description: We present a detailed study of the magnetic properties of unique cluster assembled solids namely Mn doped Ge46 and Ba8Ge46 clathrates using density functional theory. We find that ferromagnetic (FM) ground states may be realized in both the compounds when doped with Mn. In Mn2Ge44, ferromagnetism is driven by hybridization induced negative exchange splitting, a generic mechanism operating in many diluted magnetic semiconductors. However, for Mn-doped Ba8Ge46 clathrates incorporation of conduction electrons via Ba encapsulation results in RKKY-like magnetic interactions between the Mn ions. We show that our results are consistent with the major experimental observations for this system.

description: We propose statistical tests to discriminate between the finite and infinite activity of jumps in a semimartingale discretely observed at high frequency. The two statistics allow for a symmetric treatment of the problem: we can either take the null hypothesis to be finite activity, or infinite activity. When implemented on high-frequency stock returns, both tests point toward the presence of infinite-activity jumps in the data.

description: Core-collapse theory brings together many facets of high-energy and nuclear astrophysics and the numerical arts to present theorists with one of the most important, yet frustrating, astronomical questions: "What is the mechanism of core-collapse supernova explosions?" A review of all the physics and the fifty-year history involved would soon bury the reader in minutiae that could easily obscure the essential elements of the phenomenon, as we understand it today. Moreover, much remains to be discovered and explained, and a complicated review of an unresolved subject in flux could grow stale fast. Therefore, in this paper I describe what I think are various important facts and perspectives that may have escaped the attention of those interested in this puzzle. Furthermore, I attempt to describe the modern theory's physical underpinnings and briefly summarize the current state of play. In the process, I identify a few myths (as I see them) that have crept into modern discourse. However, there is much more to do and humility in the face of this age-old challenge is clearly the most prudent stance as we seek its eventual resolution.

The EFM approach for single-index models

description: Single-index models are natural extensions of linear models and circumvent the so-called curse of dimensionality. They are becoming increasingly popular in many scientific fields including biostatistics, medicine, economics and financial econometrics. Estimating and testing the model index coefficients $\boldsβ$ is one of the most important objectives in the statistical analysis. However, the commonly used assumption on the index coefficients, $\|\boldsβ\|=1$, represents a nonregular problem: the true index is on the boundary of the unit ball. In this paper we introduce the EFM approach, a method of estimating functions, to study the single-index model. The procedure is to first relax the equality constraint to one with (d-1) components of $\boldsβ$ lying in an open unit ball, and then to construct the associated (d-1) estimating functions by projecting the score function to the linear space spanned by the residuals with the unknown link being estimated by kernel estimating functions. The root-n consistency and asymptotic normality for the estimator obtained from solving the resulting estimating equations are achieved, and a Wilks type theorem for testing the index is demonstrated. A noticeable result we obtain is that our estimator for $\boldsβ$ has smaller or equal limiting variance than the estimator of Carroll et al. [J. Amer. Statist. Assoc. 92 (1997) 447-489]. A fixed-point iterative scheme for computing this estimator is proposed. This algorithm only involves one-dimensional nonparametric smoothers, thereby avoiding the data sparsity problem caused by high model dimensionality. Numerical studies based on simulation and on applications suggest that this new estimating system is quite powerful and easy to implement.

description: We argue for a convergence of crystallography, materials science and biology, that will come about through asking materials questions about biology and biological questions about materials, illuminated by considerations of information. The complex structures now being studied in biology and produced in nanotechnology have outstripped the framework of classical crystallography, and a variety of organizing concepts are now taking shape into a more modern and dynamic science of structure, form and function. Absolute stability and equilibrium are replaced by metastable structures existing in a flux of energy-carrying information and moving within an energy landscape of complex topology. Structures give place to processes and processes to systems. The fundamental level is that of atoms. As smaller and smaller groups of atoms are used for their physical properties, quantum effects become important; already we see quantum computation taking shape. Concepts move towards those in life with the emergence of specifically informational structures. We now see the possibility of the artificial construction of a synthetic living system, different from biological life, but having many or all of the same properties. Interactions are essentially nonlinear and collective. Structures begin to have an evolutionary history with episodes of symbiosis. Underlying all the structures are constraints of time and space. Through hierarchization, a more general principle than the periodicity of crystals, structures may be found within structures on different scales. We must integrate unifying concepts from dynamical systems and information theory to form a coherent language and science of shape and structure beyond crystals. To this end, we discuss the idea of categorizing structures based on information according to the algorithmic complexity of their assembly.
Enhanced accretion rates of stars on Super-massive Black Holes by star-disk interactions in galactic nuclei

description: We investigate the dynamical interaction of a central star cluster surrounding a super-massive black hole and a central accretion disk. The dissipative force acting on stars in the disk leads to an enhanced mass flow towards the super-massive black hole and to an asymmetry in the phase space distribution due to the rotating accretion disk. The accretion disk is considered as a stationary Keplerian rotating disk, which is vertically extended in order to employ a fully self-consistent treatment of stellar dynamics including the dissipative force originating from star-gas ram pressure effects. The stellar system is treated with a direct high-accuracy N-body integration code. A star-by-star representation, desirable in N-body simulations, cannot be extended to real particle numbers yet. Hence, we carefully discuss the scaling behavior of our model with regard to particle number and tidal accretion radius. The main idea is to find a family of models for which the ratio of two-body relaxation time and dissipation time (for kinetic energy of stellar orbits) is constant, which then allows us to extrapolate our results to real parameters of galactic nuclei. Our model is derived from basic physical principles and as such it provides insight into the role of physical processes in galactic nuclei, but it should be regarded as a first step towards more realistic and more comprehensive simulations. Nevertheless, the following conclusions appear to be robust: the star accretion rate onto the accretion disk and subsequently onto the super-massive black hole is enhanced by a significant factor compared to purely stellar dynamical systems neglecting the disk. This process leads to enhanced fueling of central disks in active galactic nuclei and to an enhanced rate of tidal stellar disruptions. [Abridged]

description: We study the consistency of two Higgs doublet models in light of the new bosonic particle discovery at the LHC. We work within a general setup that we call the 2HDM-X, in which the quarks couple to both scalar doublets with aligned couplings such that flavor-changing neutral currents are absent at tree level. The 2HDM-X encompasses the traditional Type I, Type II, lepton specific, and flipped models, but also provides for more general possibilities. The best fit to the current data with a suppressed tau tau signal and a b bbar signal of Standard Model strength is given by the 2HDM-X with specific parameter choices; however, very good fits are also obtained within the lepton-specific model and a democratic model, the 2HDM-D, in which both the up-type and down-type quarks couple to each doublet with equal strengths. The approach provides a general framework in which to interpret future LHC Higgs data within extensions of the Standard Model with two Higgs doublets.

Ο σχεδιασμός αποσκοπεί στην δημιουργία ενός πόλου έλξης  μελετητών, αλλά και αναψυχής ιστορικού και εκπαιδευτικού χαρακτήρα. Βασική επιδίωξη είναι η ενεργοποίηση και η προβολή του ιδιαίτερου συντακτικού, μέσω ειδικών σχεδιαστικών στρατηγικών ένταξης και ενσωμάτωσης νεωτερικών στοιχείων, σε διάλογο με τον ιστορικό χαρακτήρα του τόπου. Τα υπάρχοντα κελύφη μαζί με τον περιβάλλοντα χώρο τους, ανασχεδιάζονται και επαναχρησιμοποιούνται με γνώμονα τη διατήρηση και την ανάδειξη της αρχιτεκτονικής τους φυσιογνωμίας. Αναλυτικότερα, δίνεται έμφαση σε τρεις βασικές ενότητες, που με κριτική σκέψη, γίνεται διαφορετική προσέγγιση σε κάθε μία και ακολουθούνται διακριτές κινήσεις – επιλογές, δίνοντας όμως τη δυνατότητα να συνομιλούν μέσω κοινών αρχιτεκτονικών στοιχείων και υλικού. Πιο συγκεκριμένα, ο βυζαντινός πύργος σηματοδοτείται από ένα πιο «αφηρημένο» στέγαστρο, ο οποίος λειτουργεί ως χώρος παρατηρητηρίου, αλλά και ως την αρχή μιας περιήγησης γύρω από τα τείχη. Στο οθωμανικό «μαγειρείο» πραγματοποιείται μία αυστηρή και στιβαρή στέγαση, με σκοπό την επαναλειτουργία του ως εστία και ο μεντρεσές που λαμβάνει τη χρήση του ξενώνα, αντιμετωπίζεται με προσθήκες για την κάλυψη των απαραίτητων αναγκών. Τέλος, η συγκεκριμένη αρχιτεκτονική προσέγγιση αποσκοπεί στο να δημιουργηθεί ένας χώρος, που να ενισχύει τον χαρακτήρα της ακρόπολης, ως σταθμό αναφοράς για την πόλη των Ιωαννίνων αλλά και στην έμμεση σύνδεσή της με την νοτιοανατολική ακρόπολη του κάστρου (Ιτς Καλέ).

description: We report on the combined action of a cw diode laser and a train of ultrashort pulses when each of them drives one step of the 5S-5P-5D two-photon transition in rubidium vapor. The fluorescence from the 6P_{3/2} state is detected for a fixed repetition rate of the femtosecond laser while the cw-laser frequency is scanned over the rubidium D_{2} lines. This scheme allows for a velocity selective spectroscopy in a large spectral range including the 5D_{3/2} and 5D_{5/2} states. The results are well described in a simplified frequency domain picture, considering the interaction of each velocity group with the cw laser and a single mode of the frequency comb.

description: We present new data obtained with SpIOMM, the imaging Fourier transform spectrometer attached to the 1.6-m telescope of the Observatoire du Mont-Mégantic in Québec. Recent technical and data reduction improvements have significantly increased SpIOMM's capabilities to observe fainter objects or weaker nebular lines, as well as continuum sources and absorption lines, and to increase its modulation efficiency in the near ultraviolet. To illustrate these improvements, we present data on the supernova remnant Cas A, planetary nebulae M27 and M97, the Wolf-Rayet ring nebula M1-67, spiral galaxies M63 and NGC 3344, as well as the interacting pair of galaxies Arp 84.

description: Spin Hall effect due to random Rashba spin-orbit coupling in the two-dimensional honeycomb lattice of carbon atoms (graphene) is considered theoretically. Using the Green function method and diagrammatic technique we show that fluctuations of the Rashba interaction around zero average value give rise to nonzero spin Hall conductivity. Generally, the conductivity is not universal, but depends on the ratio of the total momentum and spin-flip relaxation rates.

description: Рассматривается один из важных для русской и западноевропейской культуры символов — облако. Этот символ актуален как для языческого, так и для христианского мировосприятия, обозначая важные понятия в русской картине мира. Данный тезис находит в статье подтверждение при обращении к сакральным, апокрифическим, фольклорным, художественным текстам. Анализ русских устойчивых единиц с компонентом облако (фразеологизмов, паремий, загадок) с точки зрения лингвокультурологии позволил выделить следующие значения этого квазисимвола: божественная сущность; граница между мирами; тяжелое душевное состояние; нечто неуловимое, не имеющее четкой формы; фантазии; ирреальное пространство и др. Использование слова облако в современной культуре в значении ‘часть виртуального пространства для хранения информации’, подтверждает его способность порождать символьные значения, актуальные для представителей разных культур, носителей разных языков, в том числе и русского.

Microscopic picture of aging in SiO2

description: We investigate the aging dynamics of amorphous SiO2 via molecular dynamics simulations of a quench from a high temperature T_i to a lower temperature T_f. We obtain a microscopic picture of aging dynamics by analyzing single particle trajectories, identifying jump events when a particle escapes the cage formed by its neighbors, and by determining how these jumps depend on the waiting time t_w, the time elapsed since the temperature quench to T_f. We find that the only t_w-dependent microscopic quantity is the number of jumping particles per unit time, which decreases with age. Similar to previous studies for fragile glass formers, we show here for the strong glass former SiO2 that neither the distribution of jump lengths nor the distribution of times spent in the cage are t_w-dependent. We conclude that the microscopic aging dynamics is surprisingly similar for fragile and strong glass formers.

description: We estimate the outer radius of the accretion disk in HLX-1 from its optical brightness and from the exponential timescale of the decline in the X-ray lightcurve after an outburst. We find that the disk is an order of magnitude smaller than the semimajor axis of the orbit. If the disk size is determined by the circularization radius near periastron, the eccentricity of the binary system must be >~ 0.95. We report on the discovery of H-alpha emission during the 2012 outburst, with a single-peaked, narrow profile (consistent with a nearly face-on view), and a central velocity displaced by ~490 km/s from that of the host galaxy.

description: Ferrocene-containing polymers are an important member in the class of redox- responsive polymers, changing e.g. their solubility or conformation upon external stimuli. We present a study of their vibrational spectra using inelastic neutron scattering, focusing on the central building block of these polymers, the organometallic ferrocene complex. The vibrational modes of a bulk ferrocene sample are compared to those of poly(vinylferrocene), poly(ferrocenyldimethylsilane) and poly(ferrocenylmethylsilane). In the former polymer, the ferrocene complex is laterally attached to the polymer chain and the vibrational spectrum shows a slight shift and broadening of the fingerprint modes in the range of 100-800 cm⁻¹ except for the ring-metal-ring stretching mode which was not detectable anymore. The latter two polymers, where the ferrocene complex is part of the polymer backbone, exhibit larger differences to the vibrational spectrum of bulk ferrocene. Moreover, several contributions to the spectra caused by methyl groups in these polymers could be identified. In order to study the influence of oxidation on ferrocene and redox-responsive polymers, we investigated the ionic compound ferrocenium triiodide and oxidized poly(vinylferrocene). It is observed that the weakening of the η⁵-complex bond by a missing electron leads to a significant shift of the fingerprint modes to lower frequencies.

description: The objective of our study was to compare recent secular trends in the morbidity and mortality rates of thyroid cancer among the children and adult populations of West Pomeranian and Pomeranian Voivodeships in 2000 and 2016. The number of thyroid cancer cases and incidence rates were retrieved from the Regional Cancer Registries for the period 2000-2016. The number of deaths and mortality rates was obtained from the cancer mortality database (2000 and 2016 by regions). The increase in the incidence rates among the female population in the Pomeranian Voivodeship was observed (from 11.31 in 2000 to 32.04 per 100,000 persons in 2016). Among the child population, the incidence has increased slightly among girls. The adult mortality rate remained unchanged during the study period and was not recorded among other populations. The highest incidence in West Pomeranian Voivodeship is observed among women in 2016 and stands at 22.46 per 100,000 population. Mortality increased slightly during the study period among the female population. The relative risk of thyroid cancer mortality was increased among the adult population of West Pomeranian Voivodeship. Therefore, both thyroid cancer morbidity and mortality are occurring mainly at the expense of the female population. These trends, combined with overall high mortality and high 15-year increase of morbidity, raise concerns on the extent to which the situation may be taking place.
