description: Pseudastrapia lobata Rothschild
Pseudastrapia lobata Rothschild, 1907c: 25 (Dutch New Guinea).
Now considered a hybrid Paradigalla carunculata X Epimachus fastosus. See Rothschild, 1911: 361; Hartert, 1919: 129; Stresemann, 1930: 13; Mayr, 1962d: 204; Gilliard, 1969: 64–65; Fuller, 1995: 54–65; and Frith and Beehler, 1998: 509– 510, pl. 14 (3).
HOLOTYPE: AMNH 679118, [immature male?], imported by Bensbach, collected somewhere in Papua Province, Indonesia (formerly Dutch New Guinea). From the Rothschild Collection.
COMMENTS: Rothschild considered this unique specimen immature. Hartert (1919: 129) thought that Epimachus ellioti should be included in the genus Pseudastrapia and that lobata was the immature of ellioti. As noted by Frith and Beehler (1998: 510), nothing about this specimen is ‘‘unequivocally indicative of immaturity,’’ and they discuss current understanding of its parentage.

description: Focal ratio degradation measurements of optical fibers for the PMAS integral field instrument have been performed using the Photometric Testbench of the Potsdam Astrophysical Institute (AIP). An effort has been made to obtain sufficiently large statistical samples of individual fiber measurements. The optimization of the measurement process has made it possible to study quantitatively the effects of different coupling methods (air--glass vs.\ immersion) and of imperfections like defocus, lateral displacement, and angular misalignment. Furthermore, the effects of mechanical stress on focal ratio degradation have been investigated, confirming the presumed cause of modal noise which is known to limit the maximum signal-to-noise one can achieve with fiber-coupled echelle spectrographs.

description: The role of dimensionality (Euclidean versus fractal), spatial extent, boundary effects and system topology on the efficiency of diffusion-reaction processes involving two simultaneously-diffusing reactants is analyzed. We present numerically-exact values for the mean time to reaction, as gauged by the mean walklength before reactive encounter, obtained via application of the theory of finite Markov processes, and via Monte Carlo simulation. As a general rule, we conclude that for sufficiently large systems, the efficiency of diffusion-reaction processes involving two synchronously diffusing reactants (two-walker case) relative to processes in which one reactant of a pair is anchored at some point in the reaction space (one walker plus trap case) is higher, and is enhanced the lower the dimensionality of the system. This differential efficiency becomes larger with increasing system size and, for periodic systems, its asymptotic value may depend on the parity of the lattice. Imposing confining boundaries on the system enhances the differential efficiency relative to the periodic case, while decreasing the absolute efficiencies of both two-walker and one walker plus trap processes. Analytic arguments are presented to provide a rationale for the results obtained. The insights afforded by the analysis to the design of heterogeneous catalyst systems are also discussed.

description: The activity of a neural network is defined by patterns of spiking and silence from the individual neurons. Because spikes are (relatively) sparse, patterns of activity with increasing numbers of spikes are less probable, but with more spikes the number of possible patterns increases. This tradeoff between probability and numerosity is mathematically equivalent to the relationship between entropy and energy in statistical physics. We construct this relationship for populations of up to N=160 neurons in a small patch of the vertebrate retina, using a combination of direct and model-based analyses of experiments on the response of this network to naturalistic movies. We see signs of a thermodynamic limit, where the entropy per neuron approaches a smooth function of the energy per neuron as N increases. The form of this function corresponds to the distribution of activity being poised near an unusual kind of critical point. Networks with more or less correlation among neurons would not reach this critical state. We suggest further tests of criticality, and give a brief discussion of its functional significance.

description: We study the moduli space of pairs consisting of a smooth cubic surface and a smooth hyperplane section, via a Hodge theoretic period map due to Laza, Pearlstein, and the second named author. The construction associates to such a pair a so-called Eckardt cubic threefold, admitting an involution, and the period map sends the pair to the anti-invariant part of the intermediate Jacobian of this cubic threefold, with respect to this involution. Our main result is that the global Torelli theorem holds for this period map; i.e., the period map is injective. To prove the result, we describe the anti-invariant part of the intermediate Jacobian as a Prym variety of a branched cover. Our proof uses results of Naranjo-Ortega, Bardelli-Ciliberto-Verra, and Nagaraj-Ramanan, on related Prym maps. In fact, we are able to recover the degree of one of these Prym maps by describing positive dimensional fibers, in the same spirit as a result of Donagi-Smith on the degree of the Prym map for connected étale double covers of genus 6 curves.

description: Using molecular dynamic simulation, we study the stretching of an adsorbed homopolymer in a poor solvent with one end held at a distance $z_e$ from the substrate. We measure the vertical force $f$ on the end of the chain as a function of the extension $z_e$ and the substrate interaction energy $w$. The force reaches a plateau value at large extensions. In the strong adsorption limit, we show that the plateau value increase linearly in $w$ in good agreement with a theoretical model. In the weak adsorption limit, a polymer globule with a layered structure is formed and elastically deformed when stretched. In both cases a simple theoretical model permits us to predict the relation between the necessary force to fully detach the polymer and its critical extension.

description: Motivated by recent work on the structure of the singularity in inhomogeneous Tolman-Bondi collapse models, we investigate the behaviour of null geodesics in the particular case where the collapse is self-similar. The presence of the homothetic Killing vector field implies that the geodesic equation can be described by an integrable Hamiltonian system, and exploiting this fact we provide a full qualitative picture for its phase flow.

description: The catenary data of a matroid $M$ of rank $r$ on $n$ elements is the vector $(ν(M;a_0,a_1,\ldots,a_r))$, indexed by compositions $(a_0,a_1,\ldots,a_r)$, where $a_0 \geq 0$,\, $a_i > 0$ for $i \geq 1$, and $a_0+ a_1 + \cdots + a_r = n$, with the coordinate $ν(M;a_0,a_1, \ldots,a_r)$ equal to the number of maximal chains or flags $(X_0,X_1, \ldots,X_r)$ of flats or closed sets such that $X_i$ has rank $i$,\, $|X_0| = a_0$, and $|X_i - X_{i-1}| = a_i$. We show that the catenary data of $M$ contains the same information about $M$ as its $\mathcal{G}$-invariant, which was defined by H. Derksen [\emph{J.\ Algebr.\ Combin.}\ 30 (2009) 43--86]. The Tutte polynomial is a specialization of the $\mathcal{G}$-invariant. We show that many known results for the Tutte polynomial have analogs for the $\mathcal{G}$-invariant. In particular, we show that for many matroid constructions, the $\mathcal{G}$-invariant of the construction can be calculated from the $\mathcal{G}$-invariants of the constituents and that the $\mathcal{G}$-invariant of a matroid can be calculated from its size, the isomorphism class of the lattice of cyclic flats with lattice elements labeled by the rank and size of the underlying set. We also show that the number of flats and cyclic flats of a given rank and size can be derived from the $\mathcal{G}$-invariant, that the $\mathcal{G}$-invariant of $M$ is reconstructible from the deck of $\mathcal{G}$-invariants of restrictions of $M$ to its copoints, and that, apart from free extensions and coextensions, one can detect whether a matroid is a free product from its $\mathcal{G}$-invariant.

description: We present BV photometry centered on the globular cluster M54 (NGC 6715). The color-magnitude diagram clearly shows a blue horizontal branch extending anomalously beyond the zero age horizontal branch theoretical models. These kinds of horizontal branch stars (also called ``blue hook'' stars), which go beyond the lower limit of the envelope mass of canonical horizontal branch hot stars, have so far been known to exist in only a few globular clusters: NGC 2808, Omega Centauri (NGC 5139), NGC 6273, and NGC 6388. Those clusters, like M54, are among the most luminous in our Galaxy, indicating a possible correlation between the existence of these types of horizontal branch stars and the total mass of the cluster. A gap in the observed horizontal branch of M54 around T(eff)= 27000 K could be interpreted within the late helium flash theoretical scenario, a possible explanation for the origin of those stars.

description: By examining the deterministic limit of a general $ε$-dependent generator for Markovian dynamics, which includes the continuous Fokker-Planck equations and discrete chemical master equations as two special cases, the intrinsic connections among mesoscopic stochastic dynamics, deterministic ODEs or PDEs, large deviations rate function, and macroscopic thermodynamic potential are established. Our result not only solves the long-lasting question on the origin of entropy function in classical irreversible thermodynamics, but also reveals an emergent feature that arises automatically during the deterministic limit, through its large deviations rate function, with both time-reversible dynamics equipped with a Hamiltonian function and time-irreversible dynamics equipped with an entropy function.

title: Appreciating metaphor for participatory practice: constructivist inquiries in a children and young people's justice organisation
Creators: name: Helme, Marion
Publisher: name: The Open University
Year: 2002

description: This thesis is framed as a first person action inquiry into participatory inquiry and practice. The context of the inquiry is a national voluntary organisation working for social justice for children and young people.

 The thesis is developed in four connected Inquiry Strands: 1) the implications of researching within a constructivist epistemology; 2) the implications of self- aware research through inquiry into the history and traditions of the researcher; 3) how appreciating metaphor can help in researching understandings of participation;4) how appreciating metaphor can enhance participatory practising.

 In connection with the first two Inquiry Strands the thesis identifies implications for epistemic and ethical practice. In connection with the third Inquiry Strand, the thesis first develops a theory of metaphor as relational and participative. This is then incorporated in a participatory methodology that can be applied in research with children, young people and adults and that embodies the output from the first two Inquiry Strands.

 . The methodology includes elicitation of stories and pictures in conversations and activities, exploration of the contexts of the inquiry, the identification and exploration of metaphors in the stories and pictures, and the development of criteria for judging these metaphors for the enhancement of practice.

 In developing the methodology the researcher draws on her experiencing of the fourth Inquiry Strand within the social justice organisation. The methodology is then used as a framework for explicating the fourth Inquiry Strand. This inquiry leads to the proposal of a set of metaphorical conditions for participatory practice: ‘purposeful activity’, ‘space for change’, ‘a safe place to learn’ and ‘reciprocal recognition’. The thesis concludes by reflecting on the four Inquiry Strands to identify learning concerning participatory inquiry in conditions of complexity and uncertainty and issues of power. Invitations are offered concerning changes in practices within the organisation, and for further research.

description: La lutte contre le changement climatique est devenue un enjeu de premier plan dans les sphères scientifiques et institutionnelles. Depuis la fin des années 2000, des organisations professionnelles ou locales testent des dispositifs de travail avec des agriculteurs en vue de les sensibiliser à cet enjeu et de faire évoluer leurs pratiques. Notre recherche porte sur l’analyse comparée de six de ces dispositifs en Pays de la Loire. Nous montrons qu’en fonction des moyens mis en oeuvre pour intéresser les agriculteurs, les groupes de travail constitués diffèrent largement, allant d’espaces de discussion entre agriculteurs convaincus par l’enjeu climatique, à des alliances entre une diversité d’agriculteurs dans le cadre de leurs réseaux de dialogue habituels. Dans tous les cas, pour inviter les agriculteurs, les porteurs des dispositifs en reformulent le sens et les objectifs. Cette reformulation opère ensuite parfois comme un rempart à l’enrôlement des agriculteurs, c’est-à-dire à un travail sur leurs connaissances de leur rapport au climat. Ainsi ces dispositifs agri-climatiques manquent leur objectif d’apprentissage.

description: Mediterranean rangelands should be conceived as socio-ecological landscapes (SEL) because of the close interaction and coevolution between socio-economic and natural systems. A significant threat to these Mediterranean rangelands is related to uncontrolled fires that can cause potential damages due to the reduction or even the loss of ecosystems. Our results show that time series of forest and grassland for unburned and burned areas are characterized by both periodic and chaotic components. The fire event caused a clear simplification of vegetation structures as well as of SEL dynamics that is more regular and predictable after the burning and less chaotic. However grassland evolution could be more predictable than forest considering the effect of fire disturbance on successional cycles and stages of the two land-cover types. In particular, we applied recurrence analysis with sliding temporal windows three-year length on the original time series. This analysis indicates that grasslands and forests behaved similarly in correspondence with the burning, although their phase states slowly diverge after fire. Recurrence is useful to study the vegetation recovery as it enables mapping landscape transitions derived from remote sensing. The approach helps stakeholders to draw landscape interventions and improve management strategies to sustain the delivery of ecosystem services.

description: Les jurys de nez riverain sont fréquemment mobilisés par les industriels pour évaluer les nuisances occasionnées par leurs activités sur le voisinage. Ces dispositifs jouissent d’une représentation collective relativement positive qui valorise l’usage collectif d’un sens réputé sous-exploité. Pourtant la forte conflictualité associée à leurs contextes de mise en place interroge les conditions de leur opérationnalisation sur le terrain et en particulier le lien entre l’activité perceptuelle collective, à proprement parler, et les enjeux de pouvoir qui s’y trament. Cet article montre que la mise en place des jurys de nez compose avec de nombreuses contraintes en partie expliquées par le caractère conflictuel de la situation. Ces contraintes ont conduit, dans le cas étudié, à des arrangements spécifiques structurant l’activité perceptuelle : mise en place d’un langage olfactif relativement simple et rapidement opérationnel sur le terrain, composition du jury façonnée par un enjeu de « représentation » des différentes parties en présence. Si le dispositif n’en est pas moins opérant dans sa capacité à faire exister institutionnellement la gêne, il s’avère toutefois très fragile car facilement soumis aux critiques et disqualifications.
Fast Nonseparable Gaussian Stochastic Process with Application to Methylation Level Interpolation

Year: 2017

description: Gaussian stochastic process (GaSP) has been widely used as a prior over functions due to its flexibility and tractability in modeling. However, the computational cost in evaluating the likelihood is $O(n^3)$, where $n$ is the number of observed points in the process, as it requires to invert the covariance matrix. This bottleneck prevents GaSP being widely used in large-scale data. We propose a general class of nonseparable GaSP models for multiple functional observations with a fast and exact algorithm, in which the computation is linear ($O(n)$) and exact, requiring no approximation to compute the likelihood. We show that the commonly used linear regression and separable models are special cases of the proposed nonseparable GaSP model. Through the study of an epigenetic application, the proposed nonseparable GaSP model can accurately predict the genome-wide DNA methylation levels and compares favorably to alternative methods, such as linear regression, random forest and localized Kriging method. The algorithm for fast computation is implemented in the ${\tt FastGaSP}$ R package on CRAN.

Nanomechanical studies of thin film porosity and graphene reinforcement in thermoplastic polymers
Creators: name: Bontoux, Luc X.
Publisher: name: No Publisher Supplied
Year: 2021

description: A study of the nanomechanical properties of graphene reinforced polymers and thin film polymers of varying porosity was conducted. Nanoindentation was used to characterize the nanoscale properties of injection molded polymers reinforced with graphene nano flakes (GNFs) and porous and densified electro-sprayed polystyrene (PS). Reduced modulus was used as the comparative property between each of these materials. Each polymer was tested with a conical indenter tip to ensure the comparability of the tests while considering the experimental restrictions of the most sensitive material.The graphene reinforced polymers were made with two varieties of matrices, nylon PA-66 and PEEK. Each matrix was reinforced with graphite at 35 wt% that was exfoliated into graphene over a multicycles process during injection molding. The number of exfoliation cycles was varied in the PEEK specimens to test the relationship between reduced modulus and graphene exfoliation. The pure PA-66 was found to have an average reduced modulus of 1.48 +/- 0.08 GPa while the PA-66 with GNFs was found to have an average reduced modulus of 1.26 +/- 0.11 GPa. The reduced modulus decrease may be attributed processing disparities or surface morphology variance. The PURE PEEK exhibited a reduced modulus of 2.90 +/- 0.31 GPa which was the lowest of the specimens tested with PEEK matrices. The PEEK with GNFs exfoliated for one (1) cycle and for five (5) cycles demonstrated higher moduli than the PEEK, with values of 3.88 +/- 0.30 GPa and 4.81 +/- 0.68 GPa, respectively. Each PEEK specimen had a decreasing trend in reduced modulus as depth increased.The electro sprayed polystyrene films were tested using a conical indenter tip. The porous films were taken from the sprayer with no post processing, while the dense films were densified via high temperature process from porous films. Each of these films was tested to 10% of their film thickness to avoid substrate effects. The porous PS was found to have an average reduced modulus of 0.136 +/- 0.036 GPa, while the dense PS was found to have an average reduced modulus of 6.92 +/- 0.80 GPa.A study of the absorbed and dissipated energy during indentation was conducted on each specimen to further compare the materials. All GNF reinforced composites demonstrated a power law trend between work of indentation and max depth, with the PEEK, PEEK+GNFs (1 cycle), and PEEK+GNFs (5 cycles) showing increasing work of indentation as the exfoliation increased. Dense PS displayed a power law trend, while porous PS demonstrated a linear relationship between work of indentation and max depth. The latter suggests that local architecture plays an important role in the response of electro-sprayed PS films.

description: In this paper, we define and evaluate a weighting scheme for neighborhoods in point sets. Our weighting takes the shape of the geometry, i.e., the normal information, into account. This causes the obtained neighborhoods to be more reliable in the sense that connectivity also depends on the orientation of the point set. We utilize a sigmoid to define the weights based on the normal variation. For an evaluation of the weighting scheme, we turn to a Shannon entropy model for feature classification that can be proven to be non-degenerate for our family of weights. Based on this model, we evaluate our weighting terms on a large scale of both clean and real-world models. This evaluation provides results regarding the choice of optimal parameters within our weighting scheme. Furthermore, the large-scale evaluation also reveals that neighborhood sizes should not be fixed globally when processing models. Finally, we highlight the applicability of our weighting scheme withing the application context of denoising.

HOLOTYPE: AMNH 679100, [adult male], collected in 1901, alledgedly in the neighborhood of Madang (= Friedrich-Wilhelmshafen), 05.18S, 145.47E (Frith and Beehler, 1998: 569), now Papua New Guinea. From the Rothschild Collection.
COMMENTS: Reichenow had a single specimen when he named P. mirabilis (it was figured in pl. 1, Journal für Ornithologie, 1902, without additional text); Rothschild (1903a: 32) placed it in the genus Janthothorax. Even in the original description, Reichenow considered the specimen to be a hybrid between Paradisaea and Seleucidis. The holotype is missing the elongated central tail feathers, but they are present in specimens that Rothschild acquired later (AMNH 294648, 679099, and 679101).

description: We consider the possibility of using one of the $D$-flat directions in the minimal supersymmetric standard model (MSSM) as the inflaton. We show that the flat direction consisting of (first generation) left- and right-handed up-squarks as well as the up-type Higgs boson may play the role of the inflaton if dominant part of the up-quark mass is radiatively generated from supersymmetric loop diagrams. We also point out that, if the R-parity violating Yukawa coupling is of $O(10^{-7})$, $R$-odd $D$-flat directions may be another possible candidate of the inflaton. Such inflation models using $D$-flat directions in the MSSM are not only testable with collider experiments but also advantageous to resolve the problem how the inflaton reheats the universe.

description: Planetary engulfment events have long been proposed as a lithium (Li) enrichment mechanism contributing to the population of Li-rich giants (A(Li) >= 1.5 dex). Using MESA stellar models and A(Li) abundance measurements obtained by the GALAH survey, we calculate the strength and observability of the surface Li enrichment signature produced by the engulfment of a hot Jupiter (HJ). We consider solar-metallicity stars in the mass range of 1-2 $\mathrm{M_\odot}$ and the Li supplied by a HJ of 1.0 $\mathrm{M_J}$. We explore engulfment events that occur near the main sequence turn-off (MSTO) and out to orbital separations of 0.1 AU. We map our results onto the Hertzsprung-Russell Diagram, revealing the statistical significance and survival time of lithium enrichment. We identify the parameter space of masses and evolutionary phases where the engulfment of a HJ can lead to Li enrichment signatures at a $5σ$ confidence level and with meteoritic abundance strengths. The most compelling strengths and survival times of engulfment-derived Li enrichment are found among host stars of 1.4 $\mathrm{M_\odot}$ near the MSTO. Our calculations indicate that planetary engulfment is not a viable enrichment pathway for stars that have evolved beyond the subgiant branch. For these sources, observed Li enhancements are likely to be produced by other mechanisms, such as the Cameron-Fowler process or the accretion of material from an asymptotic giant branch (AGB) companion. Our results do not account for second-order effects, such as extra mixing processes, which can further dilute Li enrichment signatures.

description: We report on a polarization maintaining large mode area photonic crystal fiber. Unlike, previous work on polarization maintaining photonic crystal fibers, birefringence is introduced using stress applying parts. This has allowed us to realize fibers, which are both single mode at any wavelength and have a practically constant birefringence for any wavelength. The fibers presented in this work have mode field diameters from about 4 to 6.5 micron, and exhibit a typical birefringence of 1.5e-4.

title: Modifications of radiofrequency capacitive discharge for deposition of carbon coatings
Creators: name: Goruppa, Alexander
Publisher: name: The Open University
Year: 2002

description: This thesis is an investigation of modifications of RF excited discharge for deposition of carbon coatings. Two separate discharge configurations were examined: an RF capacitive discharge with electron injection and removal by means of an emissive filament and a DC electrode, and an RF discharge with a hollow cathode powered electrode. Plasma characterization was conducted by means of an electrostatic probe and an energy and mass analysis probe. Interpretation of the electrostatic probe data in presence of RF harmonics in plasma has been discussed.
Electron injection and removal has been found to control strongly plasma potential and maximum of ion energy at the grounded electrode, reducing them to less than 10 V or increasing above 90 V accordingly. Related changes of electron temperature and density have been measured, with plasma density being increased up to an order of magnitude by electron injection. This effect has been linked with a regime, when hot filament instigates discharge inside of an electron source.
A model, based on the analysis of electron movement in an RF matrix sheath, has been developed to investigate an effect of the DC electrode on stochastic heating/cooling of electrons in the sheath. It has been demonstrated that an adequate heating of the EEDF tail and cooling of the bulk electrons could be produced by a combined effect of the sheaths of powered and grounded electrodes, assuming the multi-harmonic grounded sheath and non-equal plasma density at the sheath boundaries.
Another model, based on balance of conduction currents from RF plasma to the electrodes, has been aimed at investigation of discharge potentials. It has predicted correctly variation of time-averaged plasma potential with electron injection and removal.
Deposition experiments were conducted from both discharge configurations. Carbon coatings were analysed by means of Raman spectroscopy and scanning electron microscope (SEM). Raman spectra of coatings from the plasma with injected electrons revealed a polymeric-like nature of the coatings. SEM study of carbon films from the RF hollow cathode configuration demonstrated a wide variety of coating morphology: from porous films, consisting of separate particles, to nucleation of conical, spherical and cauliflower-like carbon phases.

description: This article constructs the moduli stack of torsionfree $G$-jet-structures in homotopy type theory with one monadic modality. This yields a construction of this moduli stack for any $\infty$-topos equipped with any stable factorization systems.
 In the intended applications of this theory, the factorization systems are given by the deRham-Stack construction. Homotopy type theory allows a formulation of this abstract theory with surprising low complexity. This is witnessed by the accompanying formalization of large parts of this work.

description: The zodiacal light is the dominant source of the mid-infrared sky brightness seen from Earth, and exozodiacal light is the dominant emission from planetary and debris systems around other stars. We observed the zodiacal light spectrum with ISOCAM over 5-16 over a wide range of orientations relative to the Sun and the ecliptic. We present theoretical models for a wide range of particle size distributions and compositions. The observed temperature is as expected for large (>10 um radius), low-albedo (< 0.08), rapidly-rotating, grey particles 1 AU from the Sun. In addition to the continuum, we detect a weak excess in the 9-11 um range, with an amplitude of 6% of the continuum. The shape of the feature can be matched by a mixture of silicates: amorphous forsterite/olivine, dirty crystalline olivine, and a hydrous silicate (montmorillonite). The presence of hydrous silicate suggests the parent bodies of those particles were formed in the inner solar nebula. Large particles dominate the size distribution, but at least some small particles (radii ~1 um) are required to produce the silicate emission feature. To compare the properties of zodiacal dust to dust around other main sequence stars, we reanalyzed the exozodiacal light spectrum for Beta Pic. The exozodiacal spectra are dominated by cold dust, with emission peaking in the far-infrared, while the zodiacal spectrum peaks around 20 um. The shape of the silicate feature from Beta Pic is nearly identical to that derived from the ISO spectrum of 51 Oph; both exozodiacal features are very different from that of the zodiacal light. The exozodiacal features are roughly triangular, peaking at 10.3 um while the zodiacal feature is more boxy.

On Possible Limit Functions on a Fatou Component in non-Autonomous Iteration

description: The possibilities for limit functions on a Fatou component for the iteration of a single polynomial or rational function are well understood and quite restricted. In non-autonomous iteration, where one considers compositions of arbitrary polynomials with suitably bounded degrees and coefficients, one should observe a far greater range of behaviour. We show this is indeed the case and we exhibit a bounded sequence of quadratic polynomials which has a bounded Fatou component on which one obtains as limit functions every member of the classical Schlicht family of normalized univalent functions on the unit disc. The proof is based on quasiconformal surgery and the use of high iterates of a quadratic polynomial with a Siegel disc which closely approximate the identity on compact subsets. Careful bookkeeping using the hyperbolic metric is required to control the errors in approximating the desired limit functions and ensure that these errors ultimately tend to zero.

description: Loborhamphus nobilis Rothschild
Loborhamphus nobilis Rothschild, 1901: 34 (Dutch New Guinea).
Now considered a hybrid Lophorina superba X Paradigalla carunculata. See Rothschild and Hartert, 1903a: 65, 72–73, 89, pl. 1; Rothschild, 1911: 357; Hartert, 1919: 129; Stresemann, 1930: 12; Mayr, 1962d: 203; Gilliard, 1969: 63–65; Fuller, 1995: 42–49; Frith and Beehler, 1998: 510–511, pl. 14 (5).
HOLOTYPE: AMNH 679113, [adult male], purchased from van Renesse van Duiven-
bode, collected somewhere in Papua Province, Indonesia (formerly Dutch New Guinea). From the Rothschild Collection.
COMMENTS: When Loborhamphus nobilis was described, Rothschild had the single specimen. Only later did he (Rothschild, 1907b: 25) obtain a second specimen (AMNH 679114), but this was not part of his type series.
Parentage of this putative hybrid is less certain than in most other cases.

Fully Distributed Resilient State Estimation based on Distributed Median Solver

description: In this paper, we present a scheme of fully distributed resilient state estimation for linear dynamical systems under sensor attacks. The proposed state observer consists of a network of local observers, where each of them utilizes local measurements and information transmitted from the neighbors. As a fully distributed scheme, it does not necessarily collect a majority of sensing data for the sake of attack identification, while the compromised sensors are eventually identified by the distributed network and excluded from the observers. For this, the overall network (not the individual local observer) is assumed to have redundant sensors and assumed to be connected. The proposed scheme is based on a novel design of a distributed median solver, which approximately recovers the median value of local estimates.
