description: Some asteroids eject dust, unexpectedly producing transient, comet-like comae and tails. First ascribed to the sublimation of near-surface water ice, mass losing asteroids (also called "main-belt comets") can in fact be driven by a surprising diversity of mechanisms. In this paper, we consider eleven dynamical asteroids losing mass, in nine of which the ejected material is spatially resolved. We address mechanisms for producing mass loss including rotational instability, impact ejection, electrostatic repulsion, radiation pressure sweeping, dehydration stresses and thermal fracture, in addition to the sublimation of ice. In two objects (133P and 238P) the repetitive nature of the observed activity leaves ice sublimation as the only reasonable explanation while, in a third ((596) Scheila), a recent impact is the cause. Another impact may account for activity in P/2010 A2 but this tiny object can also be explained as having shed mass after reaching rotational instability. Mass loss from (3200) Phaethon is probably due to cracking or dehydration at extreme (~1000 K) perihelion temperatures, perhaps aided by radiation pressure sweeping. For the other bodies, the mass loss mechanisms remain unidentified, pending the acquisition of more and better data. While the active asteroid sample size remains small, the evidence for an astonishing diversity of mass loss processes in these bodies is clear.

description: We show that a two-channel mean-field theory for a Bose gas near a Feshbach resonance allows for an analytic computation of the chemical potential, and therefore the universal constant β, at unitarity. To improve on this mean-field theory, which physically neglects condensate depletion, we study a variational Jastrow ansatz for the ground-state wave function and use the hypernetted-chain approximation to minimize the energy for all positive values of the scattering length. We also show that other important physical quantities such as Tan's contact and the condensate fraction can be directly obtained from this approach.

A Nestorian Misadventure: Frits Holm and the Chinese Nestorian Stele
Creators: name: Pearce, Nick
Publisher: name: Journal for Art Market Studies
Year: 2020

description: A commemorative medal in the Hunterian, Uni­versity of Glasgow, marks Danish journalist and adventurer, Frits Holm’s (1881–1930) attempt to remove in 1908 a monument recording the first arrival of Nestorian Christianity in China (AD.635). Unsuccessful in his attempt at its removal, Holm commissioned a replica of the stele in local stone, carved directly from the original and shipped it to New York, where, for ten years, it was displayed in the Metropolitan Museum of Art. Even at the time it was ques­tioned whether a copy had any artistic merit, but such was the Nestorian stele’s fame as a Christian document that it ended up in the Vatican Museum and was itself a source from which cast copies were made and distributed around the world. The paper discusses Frits Holm’s ‘adventure’, which provided him with the perfect opportunity for self-promotion, and addresses the position of the copy to collecting practices, especially by Westerners in China during the first decades of the twentieth centu­ry. Despite his efforts, Holm could never escape his failure to acquire the original object.

Getting even: an investigation of revenge in romantic relationships
Creators: name: Deveau, Vicki
Publisher: name: University of Calgary

description: Bibliography: p. 163-174
description: Two studies examined the types of events that spark desires for revenge in romantic relationships, actual or plotted revenge behaviours, motives for seeking revenge, functional and dysfunctional consequences of getting even, and the reasons individuals sometimes forgo getting even with their romantic partners even though they desire revenge. In Study One, participants were interviewed regarding one of three types of experiences with revenge (i.e., functional, dysfunctional, wanted to seek revenge but did not). The results revealed that intimates take revenge in response to a variety of sparking events (e.g., violations of relationship rules, violations or threats to the social identity of the relationship). Also, intimates are motivated to seek revenge in order to achieve a number of goals (e.g., redress the avenger's feelings, restore justice concerns) and they identify both functional ( e.g., corrected, educated, and/or deterred the avengee) and dysfunctional ( e.g., revenge is not the right thing to do, negative consequences for the romantic relationship) consequences of their retaliatory actions. Finally, intimates sometimes desired revenge but choose to forgo revenge due to a number of reasons ( e.g., not right thing to do, goals would not be achieved). In Study Two, participants completed several individual difference measures ( e.g., forgiveness, vengefulness, belief in a just world, self-esteem) shown in previous literatures to relate to revenge behaviours and cognitions. A week later, they were assigned to one of two recall conditions (i.e., sought revenge, wanted to seek revenge but failed to do so) and completed a series of checklists derived from the results of Study One. Contrary to expectations, individual difference measures did not relate to participants' endorsements on the checklists. However, participants' overall responses on the checklists were generally consistent with the results of Study One. These studies contribute to the literature on revenge in romantic relationships by providing much needed descriptive data that complements the few existing studies on this phenomenon and provides an important foundation on which future investigations of revenge in romantic relationships can build upon.

description: Computing the shortest path between two given locations in a road network is an important problem that finds applications in various map services and commercial navigation products. The state-of-the-art solutions for the problem can be divided into two categories: spatial-coherence-based methods and vertex-importance-based approaches. The two categories of techniques, however, have not been compared systematically under the same experimental framework, as they were developed from two independent lines of research that do not refer to each other. This renders it difficult for a practitioner to decide which technique should be adopted for a specific application. Furthermore, the experimental evaluation of the existing techniques, as presented in previous work, falls short in several aspects. Some methods were tested only on small road networks with up to one hundred thousand vertices; some approaches were evaluated using distance queries (instead of shortest path queries), namely, queries that ask only for the length of the shortest path; a state-of-the-art technique was examined based on a faulty implementation that led to incorrect query results. To address the above issues, this paper presents a comprehensive comparison of the most advanced spatial-coherence-based and vertex-importance-based approaches. Using a variety of real road networks with up to twenty million vertices, we evaluated each technique in terms of its preprocessing time, space consumption, and query efficiency (for both shortest path and distance queries). Our experimental results reveal the characteristics of different techniques, based on which we provide guidelines on selecting appropriate methods for various scenarios.

description: The confiscation of private properties by the United States of America during WWII is rarely explored. The US government seized the assets of individuals and companies it considered enemies of the State; which included German, Japanese, and Italian nationals. This article highlights the US seizure and liquidation sale of the collection of Yamanaka & Co., Inc. to underscore the need to better study the actions of the US government during WWII and its implications for the discipline of provenance research. My article builds on Yuriko Kuchiki’s research of the firm, and provides a framework on US policies before and during WWII, in order to facilitate a better understanding of what led to the confiscation of Japanese properties in the US; I incorporated additional legal, governmental, and news sources to provide a more holistic view of this particular seizure. Additionally, my work at the Freer Gallery of Art and Arthur M. Sackler Gallery, Smithsonian Institution enabled me to incorporate archival documents from the museum as well as a few other museums to further elucidate the history of Yamanaka & Co., Inc. during that tumultuous period. Despite its influential patrons and contribution in providing US museums, collectors, and other institutions with Asian art, the Japanese-owned company became enmeshed within the larger geopolitical conflicts between the US and Japan

description: I present the results of the search for an optical precursor to the naked-eye burst - GRB080319B, which reached 5.87m optical peak luminosity in the "Pi of the Sky" data. A burst of such a high brightness could have been preceded by an optical precursor luminous enough to be in detection range of our experiment. The "Pi of the Sky" cameras observed the coordinates of the GRB for about 20 minutes prior to the explosion, thus provided crucial data for the precursor search. No signal within 3 sigma limit was found. A limit of 12m (V-band equivalent) was set based on the data combined from two cameras, the most robust limit to my knowledge for this precursor.

description: A major challenge for female scientists wanting to start a family is the career break, and the gap in

their track record, that usually comes with having children. However, the challenges women face

when balancing career and family, start well before the arrival of their first child. As pregnant scientists

adjust to their changing personal life and body, they must also try to adapt their work-life and working

environment to their life changes. Using this survey research institutions can collect necessary information for improving pregnancy and maternity-related policies and regulations.

LIBRA provides two surveys, one directed to women that are or have been pregnant in your research

institute, and one for their supervising Principal Investigators.
Chinese Porcelain enters the Louvre: A Collector, his Dealers, and the Parisian Art Market (c. 1870-1912)
Creators: name: Chopard, Lucie
Publisher: name: Journal for Art Market Studies
Year: 2020

description: This study focuses on the relationship between Ernest Grandidier and the art dealers who helped him to build the most important collection of Chinese ceramics in France. The history of this incredible collection – today considered as the largest one of Chinese ceramics in France and kept at the Guimet museum in Paris - is relatively unknown. Often underestimated by the Louvre administration during the nineteenth and twentieth centuries, the Grandidier collection continues to be absent from the major studies dedicated to the history of the Louvre museum. From 1894 to 1912, Grandidier was the sole keeper of his collection and the only one to preside over his collection’s display and acquisitions. The collection archives contain two notebooks in which Grandidier recorded details for each piece in his collection. The Grandidier collection helps to define the Parisian art market and its actors by providing an ensemble of over 6,000 pieces, gathered between the late 1860s and 1912. Leaving apart the question of the collector’s taste, the close study of the purchases helps us to identify new dealers, enhances our understanding of others and provides the quantity and typology of the pieces they supply. Progress in the field of the study of the Parisian art market will provide more data and allow for a better comprehension of the complex interaction between scholars, collectors, art dealers and museums which facilitated a meeting between the French cultural milieu and Asian art in the second half of the nineteenth century.

description: We present a study of Broad Absorption Line (BAL) quasar outflows that show S IV ?1063 and S IV* ?1073 troughs. The fractional abundance of S IV and C IV peak at similar value of the ionization parameter, implying that they arise from the same physical component of the outflow. Detection of the S IV* troughs will allow us to determine the distance to this gas with higher resolution and higher signal-to-noise spectra, therefore providing the distance and energetics of the ubiquitous C IV BAL outflows. In our bright sample of 156 SDSS quasars 14% show C IV and 1.9% S IV troughs, which is consistent with a fainter magnitude sample with twice as many objects. One object in the fainter sample shows evidence of a broad S IV trough without any significant trough present from the excited state line, which implies that this outflow could be at a distance of several kpc. Given the fractions of C IV and S IV, we establish firm limits on the global covering factor on S IV that ranges from 2.8% to 21% (allowing for the k-correction). Comparison of the expected optical depth for these ions with their detected percentage suggests that these species arise from common outflows with a covering factor closer to the latter.

description: In this paper we consider the question of sensor network coverage for a 2-dimensional domain. We seek to compute the probability that a set of sensors fails to cover given only non-metric, local (who is talking to whom) information and a probability distribution of failure of each node. This builds on the work of de Silva and Ghrist who analyzed this problem in the deterministic situation. We first show that a it is part of a slightly larger class of problems which is #P-complete, and thus fast algorithms likely do not exist unless P$=$NP. We then give a deterministic algorithm which is feasible in the case of a small set of sensors, and give a dynamic algorithm for an arbitrary set of sensors failing over time which utilizes a new criterion for coverage based on the one proposed by de Silva and Ghrist. These algorithms build on the theory of topological persistence.

Remarks. The species was reported from Livonia by Kawall (1864: 303) as “ Stilbum caleus ”. According to Kawall, the observation was reported to him by Gimmerthal (in litt.). As the distribution of S. calens is mainly confined to southern Europe, Siberia and China, it is highly likely that the old record from Livonia is incorrect or based on an imported specimen.

Publisher: name: Journal for Art Market Studies
Year: 2020

description: The Princessehof Museum in Leeuwarden, theNetherlands, was founded in 1917 by the notary Nanne Ottema. He had a particular interestin Chinese ceramics and acquired an extensive collection on which he also published severalbooks. Even though Ottema never travelled to Asia, a major part of his collection was gathered there by other individuals. In particular the collections assembled during the early twentiethcentury in Indonesia (the former Dutch EastIndies) by Anne Tjibbes van der Meulen (1862-1934) and Reinier Verbeek (1841-1926) form an important part of the Princessehof collection.The former is particularly known for its collection of storage jars (also known as martaban) and the latter for its collection of Zhanghzouware. These ceramics had often for centuries been important heirloom pieces for local families, while other pieces were found during excavations. One notable example are several Tang dynasty storage jars found in the vicinity of the Borobudur. This article will discuss the formation of the Asian ceramics collection at the Princessehof by looking at these two collectors and highlighting the provenance of several exemplary objects.

The Looting of the Winter Palace in Peking in 1900-1901

Publisher: name: Journal for Art Market Studies
Year: 2020

description: An anti-foreign and anti-Christian uprising began in northern China in 1899, dubbed the “Boxer Rebellion” by the foreign powers that subsequently invaded China. In the course of events, troops of the Eight-Nation Alliance began to arrive in Beijing in August 1900 and occupied the city. During this time countless works of art were looted and many of these were subsequently traded on the international art market. A significant number of these were originally housed in the Ziguang Ge (紫光閣, Hall of Imperial Splendour), and their dispersal is a key subject of the present article. The Ziguang Ge was part of an imperial park to the west of the Forbidden City called the “Winter Palace” by Europeans. This area was given to the Germans as headquarters for the commander-in-chief for the coalition army under the command of Field Marshal Alfred Graf von Waldersee (1832-1904). Contemporary publications demonstrate how the German army settled in this area and how German soldiers treated artworks located there as their property. It is therefore not surprising that many works of art from this area are either in German museum collections today or have entered the art market from German collections. As the Ziguang Ge housed specific artworks, paintings, and other works of art with military motifs, their origin and whereabouts can be easily documented. Systematic efforts on the part of the Chinese to locate these works of art do not seem to have been made to date. It is to be hoped that at least the two large collections of officer paintings now in Chinese hands will one day be made accessible to the Chinese public.

title: Analysis of Particle Based Thermal Storage Solutions for Gas Turbine Applications

Subjects: subject: Thermal Storage
subject: Gas Turbine

description: The growth of installed renewable energy sources as a reaction to the rising interest in a low-carbon energy production has an impact on the load activity of conventional power plants. The generated power from wind parks and photovoltaic power stations is fluctuating based on the local weather conditions, which are often unpredictable and change in a short amount of time. This behavior results in many load changes of conventional power plants to provide a stable frequency in the electricity grid. The lifespan of these power plants, which are often thermal power plants, will be reduced due to the load changes and that the operating point is not the design case. This leads to higher maintenance costs, reduced efficiency and often to a higher carbon output. To maintain a constant load on conventional power plants, the fluctuating share of the electricity fed into the grid needs to be stored when the supply exceeds the demand, or the produced energy from a conventional power plant needs to be stored to enable a flexible supply. The aim of this thesis is to develop a sensible particle-based heat storage system that allows the load flexibility of combined cycle power plants (CCPP) to be increased by diverting the exhaust gas from a gas turbine, which is normally used in a steam generator to drive a steam turbine. Two systems are envisioned for this task, a fluidized bed heat exchanger (HEX) and a plate type moving bed HEX. For the first system the exhaust gas from a gas turbine will be used to fluidize a sand bed and heat the particles. With the exhaust gas fluidizing the solid bulk, additional components are reduced to bulk conveying systems which transport the heat storage material from the HEX to storage tanks and back. The second system consists of several channels arranged in parallel, which are traversed by air. The heat storage material falls between these channels, reducing the auxiliary energy to bulk conveying systems. Both systems will be analyzed numerical to gain information about viable operating conditions and the physical values of both streams. In a second step computational fluid dynamic (CFD) systems are used to optimize the proposed systems.
The Reconstruction of the Art Collection of Felix Ganz (1869-1944)
Creators: name: Neumann, Nathalie

Year: 2020

description: Felix Ganz was a businessman from Mainz in southwest Germany. He was managing director of Ludwig Ganz AG, a carpet and textile company. Felix Ganz was also an art collector with a substantial collection of art objects from the Middle East and East Asia. As soon as the National Socialists came to power, Ganz (though baptised a Protestant) was persecuted as Jew. In 1934, his company was “aryanized”, in 1941 his home was seized and in 1942 Ganz and his second wife Erna (née Benfey) were deported to Theresienstadt concentration camp. In 1944, the couple was murdered in Auschwitz. Even though his three children survived, the art collection had disappeared, and only a rough description of the items from restitution claims remains. The aim of the project presented in this article is it to reconstruct the scope and character of Felix Ganz’ art collection and to research the mechanisms of its dispersion between 1933 and 1945 as well as the location of the objects today. The article was co-authored by the great-grandson of Felix Ganz and a French-German art historian specialising in provenance research.

Novel components of the dauer larva developmental signaling pathway in Caenorhabditis elegans
Creators: name: Jensen, Victor L
Publisher: name: University of British Columbia
Year: 2010

description: In harsh conditions Caenorhabditis elegans arrests development to enter a nonaging, resistant diapause state called the dauer larva. Olfactory sensation modulates the TGF-β and insulin-like signaling pathways to control this developmental decision. The dauer pheromone is required for formation of dauer larvae. This thesis shows that bacterial pathogenesis is an input into dauer formation in addition to the known inputs of starvation, overcrowding and high temperature. This was first suggested by the overabundance of innate immunity genes found in a screen for novel synthetic dauer formation mutants. A total of 21 genes were identified in this screen, only one of which, srh-100, was previously identified to influence dauer formation. This work also characterizes new genes and functions that define early, middle, and late steps in the dauer pathway. Epistasis analysis and a GFP-tagged reporter places DAF-25 (abnormal DAuer Formation) function in the sensory cilia. DAF-25 was shown to be required for DAF-11 cilia localization as well as proper olfaction to various cues. daf-25 and daf-11 mutants have similar phenotypes and epistatic order. Intraflagellar transport is not defective in daf-25 mutants although the ciliary localization of DAF-25 itself is altered in a mutant that is defective in retrograde IFT. A Daf-c enhancing mutant originally isolated as a double mutant with a novel daf-2 allele was also identified. m708 is allelic with sdf-9 (Synthetic Dauer Formation). Epistasis analysis and allele-specific interactions place it in the daf-2 pathway as a possible DAF-2 interactor. The molecular lesion in m708 was identified to be an insertion of the mariner transposon Cemar1. This is the first identified hopping event described for this transposon family, the largest in C. elegans. Finally, zip- 5 (initially identified as a candidate DAF-16/FOXO target by serial analysis of gene expression) was shown to be a basic-leucine zipper transcription factor (bZIP) that is down regulated in a daf-2 background. zip-5 mutants show an extension of life span that is dependent on SKN-1, a bZIP-like transcription factor. ZIP-5 expression is dependant on the longevity-associated DAF-16 transcription factor and the zip-5 GATA binding sites.
Enamels “Ancient” and “Rare”: The “Summer Palace” Market in Imperial England

description: The plunder of the Yuanmingyuan in 1860 brought new kinds of Chinese decorative arts to Britain. British collectors and dealers grappled with these novelties and established the market in Chinese imperial art over the next several years, quickly bringing a known system of values to material of which they had little knowledge. Emerging connoisseurs of this material focussed their attention first on Qing enameled wares, which had clear economic, social and artistic values, which could easily be understood and communicated in an unstructured marketplace. The judgments and choices they made laid the groundwork for the market in Chinese imperial art today.

description: The common lore in the literature of neutrino mass generation is that the canonical see-saw mechanism beautifully offers an explanation for the tiny neutrino mass but at the cost of introducing right-handed neutrinos at a scale that is out of range for the current experiments. The inverse see-saw mechanism is an interesting alternative to the canonical one once it leads to tiny neutrino masses with the advantage of being testable at TeV scale. However, this last mechanism suffers from an issue of naturalness concerning the scale responsible for such small masses, namely, the parameter $μ$ that is related to lepton number violation and is supposed to be at the keV scale, much lower than the electroweak one. However, no theoretical framework was built that offers an explanation for obtaining this specific scale. In this work we propose a variation of the inverse see-saw mechanism by assuming a minimal scalar and fermionic set of singlet fields, along with a $Z_5\otimes Z_2$ symmetry, that allows a dynamical explanation for the smallness of $μ$, recovering the neat canonical see-saw formula and with right-handed (RH) neutrinos free to be at the electroweak scale, thus testable at LHC and current neutrino experiments.

Provenance Research on Chinese Paintings in American Collections of the 1950s: Sherman E. Lee, Walter Hochstadter, and the Cleveland Museum of Art

Publisher: name: Journal for Art Market Studies

description: This essay provides a window into the circulation of Chinese paintings during the tumultuous political and economic environment of the 1940s and 1950s by examining Sherman E. Lee’s acquisitions of paintings from Walter Hochstadter during Lee’s early years as curator of Asian art at the Cleveland Museum of Art from 1952-1958. This essay demonstrates that the surge in collecting Chinese paintings in postwar America and efforts to examine the major figures and historical circumstances behind this phenomenon are crucial to expanding our understanding of the history of collecting Chinese art beyond its country of origin. Lee’s acquisitions of paintings from Hochstadter in the 1950s was also facilitated by competing curators’ inability to make purchases, for example German Sinologist and art historian Ernst Aschwin Prinz zur Lippe-Biesterfeld, commonly known as Aschwin Lippe, who became a senior research fellow at the Metropolitan in 1949. Provenance research in this field crucially relies on archival research. The Freer|Sackler Galleries at the Smithsonian Institution in Washington, D.C., regularly grant researchers access to its many collections of personal papers of important curators such as Aschwin Lippe, James Cahill (1926-2014), and John Alexander Pope (1906-1902). The author consulted Hochstadter’s papers at the Center for Jewish History and the Frank Caro Archive at the Institute of Fine Arts in New York. The author also consulted Sherman Lee’s personal papers preserved by his family.

description: We present chemical abundances of Al and several Fe-Peak and neutron-capture elements for 13 red giant branch stars in the Galactic globular cluster NGC 6171 (M107). The abundances were determined using equivalent width and spectrum synthesis analyses of moderate resolution (R~15,000), moderate signal-to-noise ratio (~80) spectra obtained with the WIYN telescope and Hydra multifiber spectrograph. A comparison between photometric and spectroscopic effective temperature estimates seems to indicate a reddening value of E(B-V)=0.46 may be more appropriate for this cluster than the more commonly used value of E(B-V)=0.33. Similarly, we found that a distance modulus of (m-M)V~13.7 provided reasonable surface gravity estimates for the stars in our sample. Our spectroscopic analysis finds M107 to be moderately metal-poor with = -0.93 and also exhibits a small star-to-star metallicity dispersion (sigma=0.04). These results are consistent with previous photometric and spectroscopic studies. Aluminum appears to be moderately enhanced in all program stars (=+0.39, sigma=0.11). The relatively small star-to-star scatter in [Al/Fe] differs from the trend found in more metal-poor globular clusters, and is more similar to what is found in clusters with [Fe/H] greater than about -1. The cluster also appears to be moderately r-process enriched with =+0.32 (sigma=0.17).

description: Pandrug-resistant A. baumannii (PDRAB) is increasingly being reported but remains rare. Several case studies show that A. baumannii can acquire resistance to last resort antibiotics during treatment by single-step chromosomal mutations. However, re-emergence of the ancestral susceptible strain after withdrawal of antibiotics has been described, possibly due to fitness cost associated with acquired resistance. Therefore, PDRAB may be a transient phenotype. Epidemiological data to show this process in larger cohorts are currently lacking. In this study of 91 hospitalized patients with PDRAB we showed the frequent (60%) isolation of non-PDRAB, often susceptible only to colistin, aminoglycosides and/or tigecycline, preceding and/or following PDRAB isolation. However, the isolation of PDRAB in two outpatients, 25 and 36 days after their discharge from the hospital, suggests the potential of some PDRAB strains to persist even in the absence of antimicrobial pressure.

description: We present observations of a large-scale disc of neutral hydrogen (HI) in the nearby Fanaroff & Riley type-I radio galaxy NGC 3801 with the Westerbork Synthesis Radio Telescope. The HI disc (34 kpc in diameter and with M_HI = 1.3 x 10^9 M_sun) is aligned with the radio jet axis. This makes NGC 3801 an ideal system for investigating the evolution of a small radio source through its host galaxy's cold ISM. The large-scale HI disc is perpendicular to a known inner CO disc and dust-lane. We argue that the formation history of the large-scale HI disc is in agreement with earlier speculation that NGC 3801 was involved in a past gas-rich galaxy-galaxy merger (although other formation histories are discussed). The fact that NGC 3801 is located in an environment of several HI-rich companions, and shows indications of ongoing interaction with the nearby companion NGC 3802, strengthens this possibility. The large amounts of ambient cold ISM, combined with X-ray results by Croston et al (2007) on the presence of over-pressured radio jets and evidence for an obscuring torus, are properties that are generally not, or no longer, associated with more evolved FR-I radio sources. We do show, however, that the HI properties of NGC 3801 are comparable to those of a significant fraction of nearby low-power compact radio sources, suggesting that studies of NGC 3801 may reveal important insight into a more general phase in the evolution of at least a significant fraction of nearby radio galaxies.

description: In many information networks, data items -- such as updates in social networks, news flowing through interconnected RSS feeds and blogs, measurements in sensor networks, route updates in ad-hoc networks -- propagate in an uncoordinated manner: nodes often relay information they receive to neighbors, independent of whether or not these neighbors received the same information from other sources. This uncoordinated data dissemination may result in significant, yet unnecessary communication and processing overheads, ultimately reducing the utility of information networks. To alleviate the negative impacts of this information multiplicity phenomenon, we propose that a subset of nodes (selected at key positions in the network) carry out additional information filtering functionality. Thus, nodes are responsible for the removal (or significant reduction) of the redundant data items relayed through them. We refer to such nodes as filters. We formally define the Filter Placement problem as a combinatorial optimization problem, and study its computational complexity for different types of graphs. We also present polynomial-time approximation algorithms and scalable heuristics for the problem. Our experimental results, which we obtained through extensive simulations on synthetic and real-world information flow networks, suggest that in many settings a relatively small number of filters are fairly effective in removing a large fraction of redundant information.

Gas emissions in Planck cold dust clumps---A Survey of the J=1-0 Transitions of $^{12}$CO, $^{13}$CO, and C$^{18}$O

description: A survey toward 674 Planck cold clumps of the Early Cold Core Catalogue (ECC) in the J=1-0 transitions of $^{12}$CO, $^{13}$CO and C$^{18}$O has been carried out using the PMO 13.7 m telescope. 673 clumps were detected with the $^{12}$CO and $^{13}$CO, and 68% of the samples have C$^{18}$O emission. Additional velocity components were also identified.A close consistency of the three line peak velocities was revealed for the first time. Kinematic distances are given out for all the velocity components and half of the clumps are located within 0.5 and 1.5 kpc. Excitation temperatures range from 4 to 27 K, slightly larger than those of $T_d$. Line width analysis shows that the majority of ECC clumps are low mass clumps. Column densities N$_{H_{2}}$ span from 10$^{20}$ to 4.5$\times10^{22}$ cm$^{-2}$ with an average value of (4.4$\pm$3.6)$\times10^{21}$ cm$^{-2}$. N$_{H_{2}}$ cumulative fraction distribution deviates from the lognormal distribution, which is attributed to optical depth. The average abundance ratio of the $^{13}$CO to C$^{18}$O in these clumps is 7.0$\pm$3.8, higher than the terrestrial value. Dust and gas are well coupled in 95% of the clumps. Blue profile, red profile and line asymmetry in total was found in less than 10% of the clumps, generally indicating star formation is not developed yet. Ten clumps were mapped. Twelve velocity components and 22 cores were obtained. Their morphologies include extended diffuse, dense isolated, cometary and filament, of which the last is the majority. 20 cores are starless.Only 7 cores seem to be in gravitationally bound state. Planck cold clumps are the most quiescent among the samples of weak-red IRAS, infrared dark clouds, UC H{\sc ii} region candidates, EGOs and methanol maser sources, suggesting that Planck cold clumps have expanded the horizon of cold Astronomy.

title: Photoelektrochemische Wasserspaltung mittels adaptierter siliziumbasierter Halbleiter-Mehrfachstapelstrukturen
Creators: name: Cottre, Thorsten

description: Das Thema dieser Arbeit ist die photoelektrochemische Wasserspaltung mittels adaptierter siliziumbasierter Halbleiter-Mehrfachstapelstrukturen. Diese wurden mit oxidischen Oberflächenpassivierungsschichten (TiO2, Ta2O5) und einem angekoppelten Elektrokatalysator (Pt) ausgestattet, mit dem Ziel, diese als integrierte Photokathoden zur direkten, solargetriebenen Energieumwandlung einzusetzen. Es wurde ein direkter Zusammenhang zwischen der elektronischen Struktur, die mittels Photoelektronenspektroskopie ermittelt wurde, und der photoelektrochemischen Charakteristik hergestellt. Damit konnte gezeigt werden, dass Grenzflächeneffekte einen großen Einfluss auf die Gesamtperformance eines integrierten Systems zur lichtgetriebenen Wasserspaltung ausüben. Die Abhängigkeit der Gesamtcharakteristik von den einzelnen Komponenten (Photoabsorber, Passivierungsschicht, Elektrokatalysator) wurde mit Hilfe von geeigneten Modellsystemen bestimmt. Die Untersuchungen erfolgten mit spektroskopischen, (photo)-elektrochemischen, elektrischen, optischen und mikroskopischen Methoden. Die präparierten Photokathoden wurden unter realen Prozessbedingungen mit einer geeigneten Sauerstoffanode (RuO2-IrO2) betrieben. Den höchsten STH-Wirkungsgrad von 4,4 % erreichte das a-Si:H/a-Si:H/μc-Si:H/TiO2/Pt-Triplezellensystem unter AM1.5-Beleuchtung in 1 M H2SO4. Zusätzlich wurden alternative PV-EC-Systeme untersucht, die sich durch eine Abkopplung der Photovoltaik-Einheit von der Elektrolyse-Einheit kennzeichnen. In diesem Zusammenhang erfolgte eine Substitution des Edelmetallkatalysators durch einen kostengünstigen, auf der Erde häufiger vorkommenden Elektrokatalysator (NiOx).
