description: We realize the domain-wall/cosmology correspondence for (pseudo)supersymmetric domain walls (cosmologies) in the context of four-dimensional supergravity. The OSp(2|4)-invariant anti-de Sitter (adS) vacuum of a particular N=2 Maxwell-Einstein supergravity theory is shown to correspond to the OSp(2^*|2,2)-invariant de Sitter (dS) vacuum of a particular pseudo-supergravity model, with `twisted' reality conditions on spinors. More generally, supersymmetric domain walls of the former model correspond to pseudo-supersymmetric cosmologies of the latter model, with time-dependent pseudo-Killing spinors that we give explicitly.

description: We study systematic errors of the ground-state parameters obtained by Shifman-Vainshtein-Zakharov (SVZ) sum rules, making use of the harmonic-oscillator potential model as an example. In this case, one knows the exact solution for the polarization operator, which allows one to obtain both the OPE to any order and the parameters (masses and decay constants) of the bound states. We determine the parameters of the ground state making use of the standard procedures of the method of sum rules, and compare the obtained results with the known exact values. We show that in the situation when the continuum contribution to the polarization operator is not known and is modelled by an effective continuum, the method of sum rules does not allow to control the systematic uncertainties of the extracted ground-state parameters.

An algorithm for clock synchronization with the gradient property in sensor networks

Publisher: name: arXiv
Year: 2007
Subjects: subject: Distributed, Parallel, and Cluster Computing (cs.DC)
subject: FOS: Computer and information sciences

description: We introduce a distributed algorithm for clock synchronization in sensor networks. Our algorithm assumes that nodes in the network only know their immediate neighborhoods and an upper bound on the network's diameter. Clock-synchronization messages are only sent as part of the communication, assumed reasonably frequent, that already takes place among nodes. The algorithm has the gradient property of [2], achieving an O(1) worst-case skew between the logical clocks of neighbors. As in the case of [3,8], the algorithm's actions are such that no constant lower bound exists on the rate at which logical clocks progress in time, and for this reason the lower bound of [2,5] that forbids constant skew between neighbors does not apply.
Services within a busy period of an M/M/1 queue and Dyck paths

description: We analyze the service times of customers in a stable M/M/1 queue in equilibrium depending on their position in a busy period. We give the law of the service of a customer at the beginning, at the end, or in the middle of the busy period. It enables as a by-product to prove that the process of instants of beginning of services is not Poisson. We then proceed to a more precise analysis. We consider a family of polynomial generating series associated with Dyck paths of length 2n and we show that they provide the correlation function of the successive services in a busy period with (n+1) customers.

Subjects: subject: Economics
subject: Judgment sets
subject: Metrics

description: In the literature on judgment aggregation, an important open question is how to measure the distance between any two judgment sets. This is relevant for issues of social choice: if two individuals hold different beliefs then we might want to find a compromise that lies somewhere between them. We propose a set of axioms that determine a measure of distance uniquely. This measure differs from the widely used Hamming metric. The difference between Hamming's metric and ours boils down to one axiom. Given judgment sets A and B, this axiom says that if the propositions in A n B jointly imply that the propositions in A - B share the same truth value, then the disagreement between A and B over those propositions in A - B should be counted as a single disagreement. We consider the application of our metric to judgment aggregation, and also use the metric to measure the distance between preference rankings.

description: Genus Saraina Wanless & Clark, 1975 Type species: Saraina rubrofasciata Wanless & Clark, 1975 Diagnosis. This genus can be recognized by the shape of the copulatory organs: a counterclockwise tegulum and embolus originating on the prolateral side of tegulum (Figs 2, 9, 19, and fig. 5 G in Szűts and Scharff 2005) in males, and an epigyne with two lateral narrow openings, two bent sclerotized structures (Figs 16, 24, 25) and a long, coiled insemination duct (Figs 17, 26) in females. Saraina is a fissidentate genus. The structure of the male copulatory organs is unique: the tibia has three apophyses – ventral, medial and dorsal (Fig. 1). The whip-liked embolus is long and thin, originating from the prolateral side, and directed inwards of the cymbium (Szűts and Scharff 2005). The relationships of this genus to other salticid genera are unclear (see Wanless and Clark 1975; Dippenaar-Schoeman and Jocqué 1997). The cheliceral base in both sexes and the female copulatory organs in Saraina resemble those of some Euophryinae (see also Wanless and Clark 1975, pp. 288-289), while the male copulatory organs are more similar to those of some Thiodininae.

description: Sample pretreatment process is usually performed before real sample detection. Extraction is one of the most prevalent pretreatment methods. Due to the unequal solubility in two liquid phases, target is extracted (usually from water to organic phase) and further detected with laboratory instruments. Although the analytical instruments have high sensitivity and selectivity, they are relatively expensive and require skilful hands, which is restricted to laboratory use. Here, paper-based analytical devices (μPADs) for measuring samples extracted with organic solvents were tested. The μPADs were employed as a filter for buffer exchange, allowing the transfer of targets from organic solvent to water-based buffer, which could be specifically detected by water-based assays. As an example, polychlorinated biphenyls (PCBs) in n-hexane were detected with aptamer and gold nanoparticles (AuNPs) on μPADs within 30 min. The result of colour change can be recognized from 70.0 ng/L with a low loading amount (0.5 μL). Instead of laboratory instrumental analysis with relative high cost, this assay showed the promising utility of μPADs for target detection after sample pretreatment, which could be utilized as a general platform for inexpensive onsite detection.

description: Wir tun es heimlich, manchmal sogar nachts allein. Wir zelebrieren es mit Freunden. Ob zwischendurch schnell auf die Hand oder einen ganzen Vormittag lang gemütlich am Buffet. Unser täglich Brot nehmen wir in vielen Varianten zu uns. In dieser Ausgabe des Jungen Akademie Magazins nähern wir uns mit viel Genuss dem Thema Ernährung an – aus literarischer, symbolischer, musikalischer und wissenschaftlicher Sicht. Wir machen uns auch Gedanken über die Zukunft unserer Ernährung. Wussten Sie etwa, dass im 20. Jahrhundert der landwirtschaftliche Ertrag um das Dreifache gesteigert werden konnte? Der Grund dafür: die Erfindung des Haber-Bosch-Verfahrens. Die dadurch mögliche chemische Fixierung von Stickstoff in Ammoniak bildet die Grundlage der modernen Stickstoffdüngung. Dennoch wird diese Produktivitätssteigerung zukünftig nicht ausreichen. Denn um die wachsende Weltbevölkerung zu ernähren, müssten sich die landwirtschaftlichen Erträge bis 2050 noch einmal verdoppeln. Ganz zu schweigen vom zusätzlichen Bedarf an biomassebasierten Brennstoff en, die immer mehr mit der Nahrungsmittelproduktion konkurrieren. Die Herausforderung ist groß, und es wird Zeit, einige unserer Gewohnheiten zu überdenken. Innerhalb der Jungen Akademie wird sich die AG Nachhaltigkeit diesem Thema verstärkt widmen. Zum Auftakt des neuen Schwerpunktthemas schildert der Geograph Tobias Kümmerle, wie unser Lebensmittelkonsum in Europa die Landschaft im südamerikanischen Gran Chaco verändert. Die Agrarwissenschaftlerin Jagwida Ziolkowska beantwortet die Frage, wie viel Unmengen an Lebensmitteln jährlich verloren gehen. Und Miriam Akkermann, die eigentlich Musikwissenschaftlerin ist, hat in einem Selbstversuch ein neues Gebiet erkundet und eine Küche der Zukunft aufgesucht. Darüber hinaus beschäftigen wir uns mit den Folgen der Aufhebung des Bund-Länder-Kooperationsverbots: Welche Perspektiven ergeben sich nun für junge Wissenschaftlerinnen und Wissenschaftler im deutschen Wissenschaftssystem? Während der laufenden Diskussion haben wir die – auch innerhalb der Jungen Akademie – kontrovers diskutierte Bundesprofessur vorgeschlagen. Der Vorschlag findet sich auf Seite 32 des Magazins. Wir hoffen, dass unser Debattenbeitrag nicht nur theoretisch aufgegriffen wird. Nun aber ein köstliches Vergnügen beim Lesen wünsche ich im Namen der Redaktion, Tobi J. Erb

description: Working paper
description: In 2006 the Irish wine market was growing rapidly along with its Celtic Tiger economy (Euromonitor, 2008). Total wine sales in Ireland more than quadrupled in the seventeen-year span from 1990 to 2007 (Geraghty and Torres, 2009). While wine consumption in Ireland was growing at a rapid rate, US consumption was growing, but at a slower rate. (Euromonitor, 2010). According to Moran, Ireland sincreased consumption of wine was due primarily to improved accessibility, affordability, and branding of wine. Geraghty and Torres conducted research in Galway Ireland in 2006 among 307 wine consumers and identified three clusters of wine consumers in Ireland: the casual wine buyer, the value seeking wine buyer, and the wine traditionalist (Geraghty , 2009). These clusters provided insight into the consumers behind the increase in wine consumption. The recent recession however, has caused the wine sector in Ireland to plummet (Euromonitor, 2010). The purpose of this research was to compare the California market consumers to the consumers in the Irish market that was growing at a rapid rate to identify similarities and differences in the factors that impact wine demand in the two countries.

description: The paper begins with a brief introduction to the origins of the tradition of formalizing the determination of a rational expectations equilibrium using topological fix points. It is then suggested that fidelity to the twin economic conceptual bases of rational expectations - self-reference and infinite regress - are not encapsulated in the topological formalism. To remedy this defect, a recursion theoretic formalism for modelling rational expectations equilibria is developed.

O tipo de gado utilizado e as características estruturais das pastagens influenciam o valor da sua biodiversidade. As árvores e os arbustos dispersos eram valorizados pelos seus frutos, pela sombra para o gado, pelos efeitos benéficos na pastagem e pela sua beleza. No contexto da gestão de pastagens na Transilvânia, usavam-se tradicionalmente búfalos e gado bovino, equino e suíno, enquanto os ovinos estavam geralmente restringidos. Atualmente, estes sistemas silvopastoris estão negativamente afetados por pastoreio inadequado (isto é, sobre-pastoreio com gado ovino) e também pela remoção da vegetação lenhosa dispersa.

description: The paper uses a finite mixture modelling approach to investigate the likely determinants of relative economic performance of Irish towns. The particular success factors that we focus on are measures of connectivity, position and competitive capacity of places. Our main argument is that these determinants of success can act in different ways on different groups of towns. The mixture model is able to detect this fact. The insights provided by the model are important additions to our understanding of spatial dynamics and contribute to the policy debate on spatial planning and infrastructural investment.

description: The purpose of this article is to establish regularity and pointwise upper bounds for the (relative) fundamental solution of the heat equation associated to the weighted dbar-operator in $L^2(C^n)$ for a certain class of weights. The weights depend on a parameter, and we find pointwise bounds for heat kernel, as well as its derivatives in time, space, and the parameter. We also prove cancellation conditions for the heat semigroup. We reduce the $n$-dimensional case to the one-dimensional case, and the estimates in one-dimensional case are achieved by Duhamel's principle and commutator properties of the operators. As an application, we recover estimates of heat kernels on polynomial models in $C^2$.

description: We employ the econometric techniques of multivariate cointegration and errorcorrection models to investigate the impact of the creation of the European Monetary System (EMS) on the volume of intra-European Union (EU) exports for eight EU countries. We find that for France, Germany and Ireland, the EMS boosted the volume of intra-EU exports. In the rest of the countries, there has not been a significant effect. Another important result is that exchange rate volatility had no statistically significant long-run or short-run effect on the volume of intra-EU exports in the majority of the countries in our study.

description: Consider the single server queue with an infinite buffer and a FIFO discipline, either of type M/M/1 or Geom/Geom/1. Denote by A the arrival process and by s the services. Assume the stability condition to be satisfied. Denote by D the departure process in equilibrium and by r the time spent by the customers at the very back of the queue. We prove that (D,r) has the same law as (A,s) which is an extension of the classical Burke Theorem. In fact, r can be viewed as the departures from a dual storage model. This duality between the two models also appears when studying the transient behavior of a tandem by means of the RSK algorithm: the first and last row of the resulting semi-standard Young tableau are respectively the last instant of departure in the queue and the total number of departures in the store.

description: We investigate the locations of the satellites of relatively isolated host galaxies in the Sloan Digital Sky Survey and the Millennium Run simulation. Provided we use two distinct prescriptions to embed luminous galaxies within the simulated dark matter halos (ellipticals share the shapes of their halos, while disks have angular momenta that are aligned with the net angular momenta of their halos), we find a fair agreement between observation and theory. Averaged over scales r_p \le 500 kpc, the satellites of red, high-mass hosts with low star formation rates are found preferentially near the major axes of their hosts. In contrast, the satellites of blue, low-mass hosts with low star formation rates show little to no anisotropy when averaged over the same scale. The difference between the locations of the satellites of red and blue hosts cannot be explained by the effects of interlopers in the data. Instead, it is caused primarily by marked differences in the dependence of the mean satellite location, , on the projected distance at which the satellites are found. We also find that the locations of red, high-mass satellites with low star formation rates show considerably more anisotropy than do the locations of blue, low--mass satellites with high star formation rates. There are two contributors to this result. First, the blue satellites have only recently arrived within their hosts' halos, while the red satellites arrived in the far distant past. Second, the sample of blue satellites is heavily contaminated by interlopers, which suppresses the measured anisotropy compared to the intrinsic anisotropy.

description: The apparent contradiction between the recently observed weak charge disproportion and the traditional Mn$^{3+}$/Mn$^{4+}$ picture of the charge-orbital orders in half-doped manganites is resolved by a novel Wannier states analysis of the LDA$+U$ electronic structure. Strong electron itinerancy in this charge-transfer system significantly delocalizes the occupied low-energy "Mn$^{3+}$" Wannier states such that charge leaks into the "Mn$^{4+}$"-sites. Furthermore, the leading mechanisms of the charge order are quantified via our first-principles derivation of the low-energy effective Hamiltonian. The electron-electron interaction is found to play a role as important as the electron-lattice interaction. \ignore{A general picture of doped holes in strongly correlated charge-transfer systems is presented and applied to the study of charge order in half-doped manganites, using a novel Wannier states analysis of the LDA$+U$ electronic structure. While residing primarily in the oxygen atoms, the doped holes form additional effective $e_g$ orbitals at the low-energy scale, leading to an effective Mn$^{3+}$/Mn$^{4+}$ valence picture that enables weak charge disproportion, resolving the current serious contradictions between the recent experimental observations of charge distribution and traditional models. Furthermore, the leading mechanisms of the observed charge order are quantified via our first-principles derivation of the low-energy effective Hamiltonian

MINDFUL: A method to identify novel and diverse signals with fast unsupervised learning
Creators: name: Parulekar, Mallika
Publisher: name: F1000 Research Limited
Year: 2019

description: MINDFUL is an unsupervised machine learning algorithm that uses greedy clustering to detect rare and novel signals in gene promoter regions. The method uses a k-means clustering approach to cluster promoters aligned by transcription start sites (TSSs) into diverse classes, while also learning the optimal value of k. It is general enough to be used for any data that has categorical variables, and is not restricted to DNA.

MINDFUL is an order-of-magnitude faster than prior machine learning approaches while maintaining accuracy. It was able to detect biologically distinct characteristics in fly gene data.

description: Willingness-to-pay studies are increasingly being used in the evaluation of health care programmes. There are, however, methodological issues that need to be resolved before the potential of willingness-to-pay can be fully exploited as a tool for the economic evaluation of health care programmes. Of particular methodological interest are the consequences of varying the order in which willingness-to-pay questions are presented to respondents in contingent valuation studies. This paper examines the possibility of ordering effects in willingness-to-pay studies in health care. That is, when simultaneously asking willingness-to-pay questions about three health care programmes, does the order the programmes are presented have an impact on the reported willingness-to-pay? We present the results from a survey which allowed us to test for ordering effects and examine, in particular, if the respondent?s past experience with the health care service interacted with the ordering effects.

description: Star formation depends strongly both on the local environment of galaxies, and on the internal dynamics of the interstellar medium. To disentangle the two effects, we obtained, in the framework of the AMIGA project, Ha and Gunn r photometric data for more than 200 spiral galaxies lying in very low-density regions of the local Universe. We characterise the Ha emission, tracing current star formation, of the 45 largest and less inclined galaxies observed for which we estimate the torques between the gas and the bulk of the optical matter. We could subsequently study the Ha morphological aspect of these isolated spiral galaxies. Using Fourier analysis, we focus on the modes of the spiral arms and also on the strength of the bars, computing the torques between the gas and newly formed stars (Ha) and the bulk of the optical matter (Gunn r). We interpret the various bar/spiral morphologies observed in terms of the secular evolution experienced by galaxies in isolation. We also classify the different spatial distributions of star forming regions in barred galaxies. The observed frequency of particular patterns brings constraints on the lifetime of the various evolution phases. We propose an evolutive sequence accounting for the transitions between the different phases we could observe. Isolated galaxies appear not to be preferentially barred or unbarred. Through numerical simulations, trying to fit the Ha distributions yields constraints on the star formation law, which is likely to differ from a genuine Schmidt law. In particular, it is probable that the relative velocity of the gas in the bar also needs to be taken into account.

Low temperature Claus reactor studies

description: A small-scale fluidized bed reactor (0.1m ID, 0.86m high) was used to carry out the Claus reaction 2H₂S + SO₂ ⇌3/X Sx + 2H₂O at low temperatures (100 to 150°C) where elemental sulphur condensed on the catalyst particles (Kaiser alumina S-501, 195µm mean particle size). The experimental apparatus was similar to that described by Bonsu and Meisen (1985). The feed gas consisted of pure nitrogen mixed with H₂S and SO₂ in the ratio of 2 to 1. The H₂S concentration was varied from 200 to 1300 ppm. The feed gas flow rate ranged from approximately 1.4 to 5.6 m³/h. The corresponding U/Umf ranges were approximately 2.2 to 8.8. The bed heights varied from 0.12 to 0.38m. It was found that the experimental conversion efficiencies ranged from 60 to 96% and that they were less than those predicted thermodynamically. The conversion efficiency was found to increase with H₂S concentration and catalyst bed height; it decreased with gas flow rate. Contrary to thermodynamic predictions, the conversion efficiency increased with temperature. These results suggest that thermodynamic equilibrium was not achieved in the reactor. The decline in conversion due to catalyst fouling was measured as a function of catalyst sulphur content. The experimental results could be interpreted by means of a bubbling bed model. New analytical expressions for predicting the overall conversion and the concentration profiles were developed for reactions of order n. For the Claus reaction, where n=1.5, good agreement was found between the model predictions and experimental values. The model properly discribed the observed behavior resulting from changes in feed concentration, bed temperature, U/Umf and static bed height. The bubbling bed model was used to predict the effect of particle size on conversion for various operating gas velocities and bed dimensions. The model predictions showed that the canversion improved with decreasing particle size and that the improvement depended on U/Umf. The bubbling bed model was modified for conditions where condensed sulphur fouled the catalyst. A catalyst deactivation function, derived from first principles and based on catalyst sulphur content, was incorporated into the rate expression. The modified model predicted the the experimental measurements well and conclusions are drawn regarding the continuous operation of fluidized bed Claus reactor operating under sulphur condensing conditions. A general procedure is presented to demonstrate the applicability of the bubbling bed model in the design of large scale reactors; examples for specific conditions are given. Attrition tests were performed on the catalyst at U/Umf=5.1 and room temperatures. It was found that most of the attrition occurred in the first few hours when the catalyst particles were rough. The overall test results indicated that attrition of the catalyst was negligibly small thereby suggesting the suitability of the Kaiser S-501 catalyst for long term use in fluidized bed Claus reactors.
Excitation of spin dynamics by spin-polarized current in vortex state disks

description: A spin-polarized current with the polarization perpendicular to the plane of a vortex-state disk results in renormalization of the effective damping for a given magnetization mode, and the effective damping becomes zero if the current exceeds a threshold value. The lowest threshold current corresponds to the lowest frequency vortex gyroscopic mode. For larger values of the current the dynamic magnetization state is characterized by precession of the vortex around the dot center with non-small amplitude and higher frequency.

description: Redaktionsentscheidungen haben ihre eigenen Gesetzmäßigkeiten. Als wir uns für „Grenzen“ als Dossierthema des Junge Akademie Magazins entschieden, war kaum abzusehen, wie brandaktuell das Thema beim Erscheinen des Heftes tatsächlich sein würde. Und so erscheint im Angesicht von Grenzzäunen, Grenzkontrollen und Obergrenzen unser Magazin diesmal fast als eine tagesaktuelle Ausgabe. Grenzen haben schon immer unser Leben bestimmt. Sie begegnen uns in vielfältigster Weise. Auf dem täglichen Weg zu meinem Labor in Marburg passiere ich das Landgrafenschloss, das einst als „Mark“-Burg die Grenze zwischen den Besitzungen der Landgrafen von Thüringen und dem Erzbistum Mainz markierte. Eine längst vergessene Grenze in Zeiten der Reisefreiheit des Schengen-Raums. Wie diese neue innereuropäische Grenzenlosigkeit letztlich zur Abschottung Europas führte und die derzeitige Flüchtlingskrise verschärfte, erzählt die Ethnologin Silja Klepp in einem Gespräch. Mitte Mai organisiert sie zum Thema „Geflüchtete an deutschen Hochschulen“ eine Konferenz in Berlin. Grenzen sind wichtig. Auf meinem Fahrradweg zur Arbeit steht eine Ampel oft auf rot und weist mich in die Schranke, sie zeigt mir aber auch, wie sinnvoll Grenzen sein können, um unser Zusammenleben zu regeln. Über die positiven Seiten von Grenzen schreibt die Medienkulturwissenschaftlerin Evelyn Runge: Wo beginnt und endet Moral im Fotojournalismus? Und der Literaturwissenschaftler Caspar Battegay begibt sich in ein experimentelles Zwiegespräch mit der von uns allen gefürchteten deadline, ohne die es diese Ausgabe wohl nicht geben würde. Grenzen fordern heraus. In meinem Labor angekommen, bin ich weiterhin als Grenzgänger unterwegs. Als synthetischer Biologe forsche ich an der Grenze von Leben und Unbelebtem. Über wissenschaftliche „Grenzerfahrungen“ berichtet auch der Chemiker Hans Jakob Wörner, der an der atomaren Auflösung forscht. Der Psychologe Philipp Kanske, der Linguist Christian Stein sowie die Wissenschaftgeschichtler Fabian Krämer und Veronika Lipphardt runden das Dossier ab mit Beiträgen über zwischenmenschliche und interdisziplinäre Grenzen. Gerade letztere begegnen uns als Mitglieder der Jungen Akademie immer wieder und müssen jedesmal aufs Neue überwunden werden. Alle Schranken sind bloß des Übersteigens wegen da, schrieb Novalis. Grenzenloses Vergnügen beim Lesen wünsche ich im Namen der Redaktion Tobi J. Erb

description: Editorial decisions are subject to their own laws. When we decided on “borders” as the focus of the dossier for the Junge Akademie Magazin, we had no way of knowing what a hot topic it would become by the time we went to press. And so, in light of border fences, border controls and maximum limits, our magazine is practically as current as a daily publication. Borders have always determined our lives. We encounter them in many different ways. On my daily commute to the laboratory in Marburg, I pass the former castle of the local ruler. This border castle marked the boundary between the lands of the ruler of Thuringia and the archdiocese of Mainz, a boundary of long-lost significance in these times of free movement within the Schengen Zone. In this issue, ethnologist Silja Klepp discusses how this new intra-European borderlessness ultimately led to Europe sealing itself off and exacerbating the current refugee crisis. In this context, Klepp is organising a conference on ‘Refugees at German Universities’ to be held in Berlin in mid-May. Borders are important. When I cycle to work, I often encounter red traffic lights that limit my movement during the journey, but they also show me how useful boundaries are for regulating the way we live together. The media culture scholar Evelyn Runge writes about the positive aspects of borders: when it comes to photo journalism, where does morality begin and end? Meanwhile, the literary scholar Caspar Battegay participates in an experimental dialogue with the universally feared deadline, without which this issue would probably not exist. Borders challenge us. Once I have arrived at my laboratory, I am still engaged in crossing boundaries. As a synthetic biologist, I study the border between organic and anorganic material. The chemist Hans Jakob Wörner, who conducts research on atomic dissolution, reports on academic ‘boundary experiences’ in his work. The psychologist Philipp Kanske, the linguist Christian Stein and the historians of science Fabian Krämer and Veronika Lipphardt round out the dossier with contributions on interpersonal and interdisciplinary borders. As members of the Junge Akademie, we are continually confronted with the latter and must keep finding new ways of overcoming them. All barriers exist only to be overcome, wrote Novalis. On that note, the editorial team and I wish you boundless enjoyment while reading this issue. Tobi J. Erb
