description: We have previously described a mathematical formulation for a parton shower based on the approximation of strongly ordered virtualities of successive parton splittings. Quantum interference, including interference among different color and spin states, was included. A practical numerical implementation strategy was left unspecified. In a subsequent paper, we showed that if we add the further approximations of taking only the leading color limit and averaging over spins, we obtain a shower evolution that can be implemented as a Markov process. In this paper, we outline a strategy for including the correlations induced by parton spins.

description: We assessed differences in nutrient limitation (nitrogen and phosphorus) between benthic–littoral (in the littoral habitat) and planktonic (in the epipelagic habitat) primary producers of 7 Patagonian Andean lakes in southern South America. We conducted nutrient enrichment experiments using nitrate, ammonium, and phosphate to identify which nutrient(s) restrict primary producers’ growth in each lake habitat. We also determined the concentration of dissolved inorganic nitrogen (DIN), dissolved reactive phosphorus (PO43−), and the N to P ratio (DIN:PO43−) in the littoral and epipelagic habitats of each lake. For all the lakes, benthic–littoral primary producers were limited by N, whereas planktonic primary producers in the epipelagic habitat were colimited by N and P. Our study is the first to show that different nutrients limit the growth of benthic–littoral and planktonic primary producers in Patagonian Andean lakes, which contributes to our understanding of lake ecology in a region where information on benthic–littoral habitats is limited. This finding is important because, periphyton blooms are increasing globally in the benthic–littoral habitats of oligotrophic lakes while the pelagic habitats remain unchanged. Additionally, we found nutrient concentrations in the lakes are up to 7.4 times higher than those described in previous studies, which may be related to anthropogenic impact and natural events. If nutrient levels continue to increase, algal blooms in Patagonian Andean lakes may become a regional issue, especially in the benthic–littoral habitats.

description: La presente investigación trata de hacer un estudio exhaustivo sobre las pinturas murales de las estancias denominadas Peinador de la Reina de la Alhambra en Granada, localizadas en la parte superior de la torre Abu–l–Hayyay. Fueron pintadas entre 1539 y 1545 por Julio de Aquiles y Alexander Mayner, artistas con procedencia italiana, mostrando un exquisito programa iconográfico adaptado a los gustos cristianos con escenas mitológicas y alegóricas, paisajes navales y decoración de grutescos. Estas pinturas son consideradas como uno de los conjuntos artísticos más representativos del Renacimiento español por su riqueza pictórica y por su calidad artística e iconográfica. Sin embargo, el paso del tiempo, los agentes climatológicos, el abandono por parte de la monarquía española, la mala praxis de los visitantes al conjunto nazarí, entre otros factores, han ocasionado la desaparición parcial de los frescos. Por tanto, el objetivo de esta investigación es mostrar el estudio realizado en torno a la decoración mural del Peinador de la Reina, y la reconstrucción por medio de la disciplina artística del dibujo de algunos fragmentos de estas pinturas. De este modo, se crea una hipótesis visual que nos ayude a comprender cómo pudieron haber sido en su estado original y contribuir a la documentación de estas estancias para enriquecer el conocimiento sobre el conjunto de la Alhambra.

description: We relate three-dimensional loop quantum gravity to the combinatorial quantisation formalism based on the Chern-Simons formulation for three-dimensional Lorentzian and Euclidean gravity with vanishing cosmological constant. We compare the construction of the kinematical Hilbert space and the implementation of the constraints. This leads to an explicit and very interesting relation between the associated operators in the two approaches and sheds light on their physical interpretation. We demonstrate that the quantum group symmetries arising in the combinatorial formalism, the quantum double of the three-dimensional Lorentz and rotation group, are also present in the loop formalism. We derive explicit expressions for the action of these quantum groups on the space of cylindrical functions associated with graphs. This establishes a direct link between the two quantisation approaches and clarifies the role of quantum group symmetries in three-dimensional gravity.

description: In this work, we assess differences in nutrient limitation (nitrogen and phosphorus) between benthic-littoral (in the littoral habitat) and planktonic (in the epi-pelagic habitat) primary producers of seven Patagonian Andean lakes in southern South America. We conducted nutrient enrichment experiments using nitrate, ammonium, and phosphate to identify which nutrient(s) restrict primary producers’ growth in each lake habitat. Also, we determined the concentration of dissolved inorganic nitrogen (DIN), soluble reactive phosphorous (SRP), and the nitrogen to phosphorous ratio (DIN:SRP) at the littoral and epi-pelagic habitats of each lake. For all the lakes, benthic-littoral primary producers were limited by nitrogen, while planktonic primary producers in the epi-pelagic habitat were colimited by nitrogen and phosphorus. Our study is the first to show that different nutrients limit the growth of benthic-littoral and planktonic primary producers in Patagonian Andean lakes. This contributes to our understanding of lake ecology in a region where there is limited information on benthic-littoral habitats.

description: Phase can be reliably estimated from a single diffracted intensity image, if a faithful prior information about the object is available. Examples include amplitude bounds, object support, sparsity in the spatial or a transform domain, deep image prior and the prior learnt from the labelled datasets by a deep neural network. Deep learning facilitates state of art reconstruction quality but requires a large labelled dataset (ground truth-measurement pair acquired in the same experimental conditions) for training. To alleviate this data requirement problem, this letter proposes a zero-shot learning method. The letter demonstrates that the object-prior learnt by a deep neural network while being trained for a denoising task can also be utilized for the phase retrieval, if the diffraction physics is effectively enforced on the network output. The letter additionally demonstrates that the incorporation of total variation in the proposed zero-shot framework facilitates the reconstruction of similar quality in lesser time (e.g. ~8.5 fold, for a test reported in this letter).

description: Resonant tunneling through quantum dot under a finite bias voltage at zero temperature is investigated by using the adaptive time-dependent density matrix renormalization group(TdDMRG) method. Quantum dot is modeled by the Anderson Hamiltonian with the 1-D nearest-neighbor tight-binding leads. Initially the ground state wave function is calculated with the usual DMRG method. Then the time evolution of the wave function due to the slowly changing bias voltage between the two leads is calculated by using the TdDMRG technique. Even though the system size is finite, the expectation values of current operator show steady-like behavior for a finite time interval, in which the system is expected to resemble the real nonequilibrium steady state of the infinitely long system. We show that from the time intervals one can obtain quantitatively correct results for differential conductance in a wide range of bias voltage. Finally we observe an anomalous behavior in the expectation value of the double occupation operator at the dot $$ as a function of bias voltage.

description: Quantum annealing is an emerging new platform for combinatorial optimization, requiring an Ising model formulation for optimization problems. The formulation can be an essential obstacle to the permeation of this innovation into broad areas of everyday life. Our research is aimed at the proposal of a Petri net modeling approach for an Ising model formulation. Although the proposed method requires users to model their optimization problems with Petri nets, this process can be carried out in a relatively straightforward manner if we know the target problem and the simple Petri net modeling rules. With our method, the constraints and objective functions in the target optimization problems are represented as fundamental characteristics of Petri net models, extracted systematically from Petri net models, and then converted into binary quadratic nets, equivalent to Ising models. The proposed method can drastically reduce the difficulty of the Ising model formulation.

In particular, by means of the Morales-Ramis theory, these Hamiltonian systems are non-integrable through rational first integrals.

description: We measure the number Omega(phi) of mechanically stable states of volume fraction phi of a granular assembly under gravity. The granular entropy S(phi) = log Omega(phi) vanishes both at high density, at phi = phi_rcp, and a low density, at phi = phi_rvlp, where phi_rvlp is a new lower bound we call random very loose pack. phi_rlp is the volume fraction where the entropy is maximal. These findings allow for a clear explanation of compaction experiments, and provide the first first-principle definition of the random loose volume fraction. In the context of the statistical mechanics approach to static granular materials, states with phi < phi_rlp are characterized by a negative temperature.

description: Context: Local reductions of the stellar velocity dispersion in the central regions of galaxies are known as sigma-drops. Knowing the origin of these features can lead to better understanding of inner galactic dynamics. Aims: We present a sample of 20 sigma-drop galaxies matched with a control sample of galaxies without sigma-drop in order to search for correlations between sigma-drops and the properties, primarily morphological, of the nuclear zones and discs of their host galaxies. Methods: We study the dust and Halpha distribution at 0.1 arcsec scale, using Hubble Space Telescope imaging, in the circumnuclear zones of the two samples of galaxies, searching for differences and trying to establish a link between the nuclear kinematics and the host morphology. We have also considered the CO and HI emission of the galaxies and their luminosity profiles. Results: We classify the two samples following both morphological parameters and the luminosity profiles. We find a larger fraction of nuclear dust spirals and Halpha rings in the sigma-drop sample. We also find that the fraction of Seyfert galaxies in the sigma-drop sample is bigger than that of LINERs and that the reverse is true for the control sample. Conclusions: Our findings are evidence that a $σ$-drop is very probably due to inflow-induced star formation in a dynamically cool disc, or in a gas ring, shock focused by an inner Lindblad resonance above a certain critical density level. The same mechanism that feeds the nuclear ring or the nuclear disc is probably reponsible for the higher rate of Seyfert galaxies among the $σ$-drop hosts.

description: Attractive interaction between spinless fermions in a two-dimensional lattice drives the formation of a topological superfluid. But the topological phase is dynamically unstable towards phase separation when the system has a high density of states and large interaction strength. This limits the critical temperature to an experimentally challenging regime where, for example, even ultracold atoms and molecules in optical lattices would struggle to realize the topological superfluid. We propose that the introduction of a weaker longer-range repulsion, in addition to the short-range attraction between lattice fermions, will suppress the phase separation instability. Taking the honeycomb lattice as an example, we show that our proposal significantly enlarges the stable portion of the topological superfluid phase and increases the critical temperature by an order of magnitude. Our work opens a route to enhance the stability of topological superfluids by engineering inter-particle interactions.

description: VI$_{3}$ is a ferromagnet with planar honeycomb sheets of bonded V$^{3+}$ ions held together by van der Waals forces. We apply neutron spectroscopy to measure the two dimensional ($J/J_{c} \approx 17$) magnetic excitations in the ferromagnetic phase, finding two energetically gapped ($Δ\approx k_{B} T_{c} \approx$ 55 K) and dispersive excitations. We apply a multi-level spin wave formalism to describe the spectra in terms of two coexisting domains hosting differing V$^{3+}$ orbital ground states built from contrasting distorted octahedral environments. This analysis fits a common nearest neighbor in-plane exchange coupling ($J$=-8.6 $\pm$ 0.3 meV) between V$^{3+}$ sites. The distorted local crystalline electric field combined with spin-orbit coupling provides the needed magnetic anisotropy for spatially long-ranged two-dimensional ferromagnetism in VI$_{3}$.

description: Twelve years after the first significant discovery in the pre-salt layer, pre-salt fields represent about 55% of Brazil’s oil production. Following an economic recession, an increase in the country credit risk, and the 2014 oil price collapse, we analyze the production of petroleum in the pre-salt zones by identifying: the break-even price (BEP), and the effect of oil price, price volatility, productivity, and country risk on wells drilled. To identify these effects on the number of wells drilled into the pre-salt zone, we estimate 100 cointegrating vector autoregression models that specify 10 measures of price and 10 break-even prices. The most accurate model measures oil prices using WTI, has a BEP of $62 per barrel (2018 prices). Results indicate the negative and positive effect, respectively, of raising the country risk and productivity on the number of development wells drilled into the pre-salt zone.

description: We study the sensitivity of the Fermilab Short-Baseline Neutrino (SBN) experiments, MicroBooNE, ICARUS, and SBND, to MeV- to GeV-scale inelastic dark matter interacting through a dark photon mediator. These models provide interesting scenarios of light thermal dark matter, which, while challenging to probe with direct and indirect detection experiments, are amenable to accelerator-based searches. We consider production of the dark sector states with both the Fermilab Booster 8 GeV and NuMI 120 GeV proton beams and study the signatures of scattering and decay of the heavy excited dark state in the SBN detectors. These distinct signatures probe complementary regions of parameter space. All three experiments will be able to cover new ground, with an excellent near-term opportunity to search for cosmologically motivated targets explaining the observed dark matter abundance.

description: We aim to assess the effectiveness of feedback controlled resonant drift pacing as a method for low energy defibrillation. Antitachycardia pacing is the only low energy defibrillation approach to have gained clinical significance, but it is still suboptimal. Low energy defibrillation would avoid adverse side effects associated with high voltage shocks and allow the application of ICD therapy where it is not tolerated today. We present results of computer simulations of a bidomain model of cardiac tissue with human atrial ionic kinetics. Re-entry was initiated and low energy shocks were applied with the same period as the re-entry, using feedback to maintain resonance. We demonstrate that such stimulation can move the core of re-entrant patterns, in the direction depending on location of electrodes and a time delay in the feedback. Termination of re-entry is achieved with shock strength one order of magnitude weaker than in conventional single-shock defibrillation. We conclude that resonant drift pacing can terminate re-entry at a fraction of the shock strength currently used for defibrillation and can potentially work where antitachycardia pacing fails, due to the feedback mechanisms. Success depends on a number of details which these numerical simulations have uncovered. \emph{Keywords} Re-entry; Bidomain model; Resonant drift; ICD; Defibrillation; Antitachycardia pacing; Feedback.

These objects were pre-selected to have short lifetimes based on preliminary measurements of their proximity zone sizes, and were then targeted for high quality follow-up sub-mm, optical, and infrared observations required to increase the measurements' precision and securely determine their lifetimes. By comparing these proximity zone sizes to mock quasar spectra generated from radiative transfer simulations at a range of different lifetimes, we deduce extremely short lifetimes $t_{\rm Q}<10^4$ yr for four objects in our sample, whereas the remaining quasars are consistent with longer lifetimes of $t_{\rm Q}\gtrsim 10^5$ yr. These young objects with small proximity zones represent $\lesssim10\%$ of the quasar population as a whole. We compare our results in detail to other studies on timescales of quasar activity, which point towards an average lifetime of $t_{\rm Q}\sim10^6$ yr for the quasar population. This is consistent with finding newly turned on quasars approximately $\sim 1-10\%$ of the time. These young quasars represent an unique opportunity to study triggering and feedback mechanisms of SMBHs, since the onset of their UV luminous quasar phase happened only recently, and therefore traces of this process might still be observable.

Analipus japonicus (Harv.) Wynne (Phaeophyta): studies of its biology and taxonomy
Creators: name: Nelson, Wendy Alison
Publisher: name: University of British Columbia
Year: 2010

description: A culture and light microscope study was made of the development, morphology and anatomy of Analipus japonicus (Harv.) Wynne (Phaeophyta). Its life history was observed in culture and followed in the field over a period of two years. Cytological studies employing microspectrophotometry to measure relative DNA content confirmed the life history to be an alternation of isomorphic generations - verifying the work of Abe (1935a,b, 1936) which has been questioned in the literature. The unilocular plants proved to be diploid. Meiosis occurs in the unilocular sporangia, resulting in the formation of haploid unispores. Haploid plurilocular plants were the only plants of A.japonicus found in British Columbia. A survey of herbarium specimens and collections outside British Columbia showed that only plurilocular populations cccur in most of the eastern portion of A.japonicus' geographic range (Alaska, B.C., Washington, Oregon, California). Unilocular plants occur in Japan and in one site in California. Prior to this study the rarity of this stage of A.japonicus' life history had not been realised. The ecology of A.japonicus in British Columbia was studied at a site in the Strait of Georgia and at two sites in Earkley Sound on the west coast of Vancouver Island. A comparison was made of A.japonicus and the subantarctic alga Caepidium antarcticum J.Ag. (to which A.japonicus has been likened in the literature). Although many similarities exist between them, it is concluded that these plants are generically distinct. The affinities of Caepidium will remain unclear until life history data are available. It is concluded from an evaluation of the order Ralfsiales (into which A.japonicus has been recently placed) that this order should not be recognised., The placement of A.japonicus into the Ralfsiaceae is evaluated and considered inappropriate. The use of the family Heterochordariaceae for A.japonicus and the placement of this family in the Ectocarpales are advocated.

description: We present a generic algorithm for computing discrete logarithms in a finite abelian p-group H, improving the Pohlig-Hellman algorithm and its generalization to noncyclic groups by Teske. We then give a direct method to compute a basis for H without using a relation matrix. The problem of computing a basis for some or all of the Sylow p-subgroups of an arbitrary finite abelian group G is addressed, yielding a Monte Carlo algorithm to compute the structure of G using O(|G|^0.5) group operations. These results also improve generic algorithms for extracting pth roots in G.

description: The evolution of satellite galaxies is shaped by their constant interaction with the circum galactic medium surrounding central galaxies, which in turn may be affected by gas and energy ejected from the central supermassive black hole. However, the nature of this coupling between black holes and galaxies is highly debated and observational evidence remains scarce. Here we report an analysis of archival data on 124,163 satellite galaxies in the potential wells of 29,631 dark matter halos with masses between 10$^{12}$ and $10^{14}$ solar masses. We find that quiescent satellites are relatively less frequent along the minor axis of their central galaxies. This observation might appear counterintuitive as black hole activity is expected to eject mass and energy preferentially in the direction of the minor axis of the host galaxy. However, we show that the observed signal results precisely from the ejective nature of black hole feedback in massive halos, as active galactic nuclei-powered outflows clear out the circumgalactic medium, reducing the ram pressure and thus preserving star formation. This interpretation is supported by the IllustrisTNG suite of cosmological numerical simulations, where a similar modulation is observed even though the sub-grid implementation of black hole feedback is effectively isotropic. Our results provide compelling observational evidence for the role of black holes in regulating galaxy evolution over spatial scales differing by several orders of magnitude.

Die Institutionalisierung und Professionalisierung der Kinderbetreuung und -erziehung als Erwerbsarbeit im Wien des 19. Jahrhunderts
Creators: name: Ledermüller, Susanna
Year: 2020

description: Die vorliegende Diplomarbeit beschreibt welche ökonomischen und sozialen Prozesse die Institutionalisierung und Professionalisierung der Kinderbetreuung und -erziehung als Erwerbsarbeit im Wien des 19. Jahrhunderts bedingten. In einem theoretischen Teil werden der Arbeitsbegriff, Theorien zur Professionalisierung der Hausarbeit und die Definition "Kind und Kindheit" ausgemacht und beschrieben. In einem zweiten Teil wird der historische Kontext des Themas dargestellt, allen voran die Folgen der Industrialisierung für das Leben und Arbeiten der Menschen und deren politische und soziale Auswirkungen auf "das Kind". Anschließend werden die ersten Institutionen der Kleinkinderbetreuung in Europa und schließlich der Entstehung solcher in Wien Anfang des 19. Jahrhunderts beschrieben. Im Laufe des Jahrhunderts werden in Wien verschiedene Institutionen für die Betreuung und Erziehung von Kleinkindern gegründet. Kinderbetreuung außerhalb der Familie wird zu einer Frage der Schicht. Ärmere Familien schicken ihre Kinder, wenn die einer Erwerbsarbeit außer Haus nachgehend müssen, in Bewahranstalten, in welchen die Kinder vor Verwahrlosung und Kriminalität bewahrt werden. Reichere Familien leisten es sich ihr Kind in einen Kindergarten, nach dem pädagogischen Konzept Fröbels, zu bringen, in welchen die Kinder gefördert werden. Erst gegen Ende des 19. Jahrhunderts beginnt die Entstehung öffentlicher Kindergärten , die für erwerbstätige Mütter eine Entlastung sein sollen und unabhängig von der sozialen Schicht allen Kindern zugänglich gemacht werden sollen. Mit diesen Prozessen der Institutionalisierung einhergehend kommt es auch zur Professionalisierung des Personals. Kinderbetreuung wird zur Erwerbsarbeit, vor allem für Frauen. Die wichtigsten Schritte des Professionalisierungsprozesses bis zum Entstehen des Berufes der Kindergärtnerin in der Stadt Wien werden schließlich geschildert.

description: The paper studies distributed static parameter (vector) estimation in sensor networks with nonlinear observation models and noisy inter-sensor communication. It introduces \emph{separably estimable} observation models that generalize the observability condition in linear centralized estimation to nonlinear distributed estimation. It studies two distributed estimation algorithms in separably estimable models, the $\mathcal{NU}$ (with its linear counterpart $\mathcal{LU}$) and the $\mathcal{NLU}$. Their update rule combines a \emph{consensus} step (where each sensor updates the state by weight averaging it with its neighbors' states) and an \emph{innovation} step (where each sensor processes its local current observation.) This makes the three algorithms of the \textit{consensus + innovations} type, very different from traditional consensus. The paper proves consistency (all sensors reach consensus almost surely and converge to the true parameter value,) efficiency, and asymptotic unbiasedness. For $\mathcal{LU}$ and $\mathcal{NU}$, it proves asymptotic normality and provides convergence rate guarantees. The three algorithms are characterized by appropriately chosen decaying weight sequences. Algorithms $\mathcal{LU}$ and $\mathcal{NU}$ are analyzed in the framework of stochastic approximation theory; algorithm $\mathcal{NLU}$ exhibits mixed time-scale behavior and biased perturbations, and its analysis requires a different approach that is developed in the paper.
