description: We propose selection cuts on the LHC top-antitop production sample which should enhance the sensitivity to New Physics signals in the study of the top-antitop invariant mass distribution. We show that selecting events in which the top-antitop object has little transverse and large longitudinal momentum enlarges the quark-fusion fraction of the sample and therefore increases its sensitivity to New Physics which couples to quarks and not to gluons. We find that systematic error bars play a fundamental role and assume a simple model for them. We check how a non-visible new particle would become visible after the selection cuts enhance its resonance bump. A final realistic analysis should be done by the experimental groups with a correct evaluation of the systematic error bars.

Numerical simulation of hydraulic fracture, stress shadow effects and induced seismicity in jointed rock
Creators: name: Zangeneh, Neda
Publisher: name: University of British Columbia
Year: 2013

description: Hydraulic fracturing provides a means to optimize shale gas completions by enhancing the permeability of what is otherwise very tight rock. However, the coupled nature of the processes involved (e.g., thermo-hydro-mechanical-chemical), interlinked with geological variability and uncertainty, makes it extremely difficult to fully predict the spatial and temporal evolution of the hydrofrac and surrounding invaded zone. Numerical design tools have been developed to contend with this complexity, but these have largely focused on the mechanics of brittle fracture propagation at the expense of making simplifying assumptions of the host geology within which the hydraulic fracture is propagating, namely treating it as a linear elastic continuum. In contrast, the reservoir rock conditions are much more complex. Present are natural discontinuities, including bedding planes, joints, shears and faults superimposed by the in-situ stress field. The natural discontinuities under the applied in-situ stress have the potential to either enhance or diminish the effectiveness of the hydraulic fracturing treatment and subsequent hydrocarbon production. Improved understanding of the interactions between the hydraulic fracture and natural fractures under the stress field would allow designers and operators to achieve more effective hydraulic fracturing stimulation treatments in unconventional reservoirs. To better account for the presence of natural discontinuities in shale gas reservoirs, this thesis investigates the use of the 2-D commercial distinct-element code UDECTM (Itasca Consulting Group, 1999) to simulate the response of a jointed rock mass subjected to static loading and hydraulic injection. The numerical models are developed to illustrate some important concepts of hydraulic fracturing such as the effect of natural fractures in fracture connectivity, effects of stress shadowing in multiple horizontal well completion, and the effect of fluid injection in induced seismicity, so they can be used to qualitatively evaluate the effects of the in-situ environment on the design and the consequences of the design on the in-situ environment.

description: Το ελληνικό χρηματοπιστωτικό σύστημα, αποτελεί ίσως τον πιο διεθνοποιημένο τομέα της ελληνικής οικονομίας τα τελευταία χρόνια. Οι τράπεζες τα τελευταία σαράντα χρόνια, πέρασαν από πολλά στάδια, για να φτάσουν στη σημερινή μορφή. Η διαδικασία μετασχηματισμού τους δεν ήταν σε καμία περίπτωση ούτε εύκολη ούτε ανώδυνη. Μετεξελίχθηκαν από μικρές επιχειρήσεις στα αρχικά τους στάδια, με λίγα άτομα προσωπικό, σε τεραστίου μεγέθους επιχειρήσεις διεθνούς βεληνεκούς, με χιλιάδες εργαζομένους και διεθνή παρουσία. Στην πάροδο των ετών το σύστημα εκσυγχρονίστηκε, τόσο με τη βοήθεια των εργαζομένων στις τράπεζες, αλλά κυρίως με τη βοήθεια του συναλλασσομένου κοινού, που το αγκάλιασε με την εμπιστοσύνη του και το στήριξε. Το ισχυρό τραπεζικό σύστημα έγινε βασικός μοχλός ανάπτυξης για την εθνική μας οικονομία και κατ΄ επέκταση για την ευημερία της κοινωνίας. Στις μέρες μας, το τραπεζικό περιβάλλον έχει αλλάξει με τη συνεχή ανάπτυξη νέων τεχνολογιών. Ο ανταγωνισμός μεταξύ των πιστωτικών ιδρυμάτων και η καινοτομία έχουν βοηθήσει στην ανάπτυξη εναλλακτικών δικτύων παροχής υπηρεσιών και προϊόντων. Πλέον, για πολλές συναλλαγές δεν απαιτείται η παρουσία του κοινού στα φυσικά καταστήματα της τράπεζας, των οποίων ο αριθμός μειώνεται. Είναι το συναλλακτικό κοινό ικανοποιημένο από την τράπεζα με τη μορφή που λειτουργεί σήμερα και τις υπηρεσίες που παρέχει; Είναι εξοικειωμένο το κοινό με τις νέες τεχνολογίες και κατά πόσο τις θεωρεί ποιοτικές; Εμπιστεύεται το τραπεζικό σύστημα ή έχει κλονιστεί η πίστη του μετά τον περιορισμό κίνησης κεφαλαίων που τέθηκε στη χώρα μας το 2015; Στην παρούσα διπλωματική επιχειρείται να διερευνηθούν τα παραπάνω ερωτήματα με τη χρήση της θεωρίας του Μοντέλου Αποδοχής Τεχνολογίας (ΤΑΜ). Με την εφαρμογή πρωτογενούς έρευνας μέσω της ποσοτικής μεθόδου προέκυψαν σημαντικά συμπεράσματα που αποδεικνύουν ότι το συναλλακτικό κοινό περιβάλλει με εμπιστοσύνη το ελληνικό τραπεζικό σύστημα. Φάνηκε επίσης πως οι τέσσερις συστημικές τράπεζες, αποτελούν στη συντριπτική τους πλειοψηφία την πρώτη επιλογή του κοινού για συνεργασία.

description: We use spitzer-IRAC data to identify near-infrared counterparts to submillimeter galaxies detected with Herschel-SPIRE at 250um in the Herschel Astrophysical Terahertz Large Area Survey (H-ATLAS). Using a likelihood ratio analysis we identify 146 reliable IRAC counterparts to 123 SPIRE sources out of the 159. We find that, compared to the field population, the SPIRE counterparts occupy a distinct region of 3.6 and 4.5um color-magnitude space, and we use this property to identify a further 23 counterparts to 13 SPIRE sources. The IRAC identification rate of 86% is significantly higher than those that have been demonstrated with wide-field ground-based optical and near-IR imaging of Herschel fields. We estimate a false identification rate of 3.6%, corresponding to 4 to 5 sources. Among the 73 counterparts that are undetected in SDSS, 57 have both 3.6 and 4.5um coverage. Of these 43 have [3.6] - [4.5]> 0 indicating that they are likely to be at z > 1.4. Thus, ~ 40% of identified SPIRE galaxies are likely to be high redshift (z > 1.4) sources. We discuss the statistical properties of the IRAC-identified SPIRE galaxy sample including far-IR luminosities, dust temperatures, star-formation rates, and stellar masses. The majority of our detected galaxies have 10^10 to 10^11 L_sun total IR luminosities and are not intense starbursting galaxies as those found at z ~ 2, but they have a factor of 2 to 3 above average specific star-formation rates compared to near-IR selected galaxy samples.

A STUDY ON CUSTOMERS' ATTITUDE TOWARDS CREDIT CARDS IN ERODE CITY
Creators: name: Dr. V. Geetha
Publisher: name: Zenodo
Year: 2025

description: This study explores the attitudes of consumers in a European city toward the use of credit cards, examining their perceptions, preferences, and behavioural patterns. Through a combination of surveys and interviews, the research identifies key factors influencing credit card adoption, such as convenience, security concerns, financial literacy, and marketing strategies by financial institutions. The study also delves into the psychological aspects of credit card usage, including spending habits and debt management. Findings suggest that while credit cards offer perceived financial flexibility, concerns around debt accumulation and interest rates play a significant role in shaping consumer behaviour. The study concludes by offering recommendations for both financial institutions and policymakers to promote responsible credit card usage and improve customer satisfaction.

description: Three results in p-convex geometry are established. First is the analogue of the Levi problem in several complex variables, namely: local p-convexity implies global p-convexity. The second asserts that the support of a minimal p-dimensional current is contained in the p-hull of the boundary union with the "core" of the space. Lastly, the exteme rays in the convex cone of p-positive matrices are characterized. This is a basic result with many applications.

description: This Letter presents a search for pair production of heavy down-type quarks decaying via b'->Wt in the lepton + jets channel, as b'b'->WtWt->bbWWWW->lvbbqqqqqq. In addition to requiring exactly one lepton, large missing transverse momentum and at least six jets, the invariant mass of nearby jet pairs is used to identify high transverse momentum W bosons. In data corresponding to an integrated luminosity of 1.04 fb^-1 from pp collisions at sqrt(s) = 7 TeV recorded with the ATLAS detector, a heavy down-type quark with mass less than 480 GeV is excluded at the 95% confidence level.

description: We analyse the role played by system-environment correlations in the emergence of non-Markovian dynamics. By working within the framework developed in Breuer et al., Phys. Rev. Lett. 103, 210401 (2009), we unveil a fundamental connection between non-Markovian behaviour and dynamics of system-environment correlations. We derive an upper bound to the rate of change of the distinguishability between different states of the system that explicitly depends on the development and establishment of correlations between system and environment. We illustrate our results using a fully solvable spin-chain model, which allows us to gain insight on the mechanisms triggering non-Markovian evolution.

description: Crambe Vosmaer, 1880
 Diagnosis. Encrusting sponges characterized by having aster-like desmas (astroclones or sphaeroclones), along with a category of large choanosomal (tylo)styles, a category of small ectosomal subtylostyles, and one or two categories of anchorateunguiferate isochelae. Irregularly spiny microxeas occur in some species.
 Remarks. It has long been recognized that, for unknown reasons, most populations of Crambe crambe and some of Crambe acuata produce neither desmas nor isochelae (e.g. Boury-Esnault, 1971; Vacelet et al., 1976). This fact has largely complicated both species and genus diagnoses in Crambe. However, it was recently found that laboratory populations of C. crambe reared in seawater experimentally enriched with silicic acid produce up to four spicule types, desmas and isochelae included, that were otherwise missing in most natural populations (Maldonado et al., 1999). Therefore, it must be concluded that production of asteroid desmas and isochelae is a genetic trait shared by all individuals of all Crambe species. The skeletal reduction observed in many natural populations of C. crambe does not appear to have a genetic basis, but seems to be a phenotypic skeletal inhibition induced by limiting levels of silicic acid in sublittoral waters. Consequently, the presence / absence of desmas and isochelae must be used cautiously in the taxonomy of both Crambe and other crambeids.
 The genus Crambe is here reported for the ®rst time from the Paci®c Ocean. It is noteworthy that it has not been reported to date from the well-known Caribbean sponge fauna or in nearby zones of the Central Paci®c, such as the Galapagos Islands, which have recently been surveyed (Desqueyroux-FauÂndez and van Soest, 1997; authors, unpublished data). Nevertheless, the presence of the genus in the western Paci®c stratigraphic sediments can be inferred from the fossil sphaeroclones found in Lower Tertiary strata of Oamaru (New Zealand). Such characteristic sphaeroclones, though formerly attributed to the genus Vetulina by Hinde and Holmes (1892), most likely belong to a fossil species of Crambe (Uriz and Maldonado, 1995), namely Crambe oamaruensis (Hinde and Holmes, 1892).

description: Τα τελευταία χρόνια, η ραγδαία ανάπτυξη των Τεχνολογιών Πληροφορίας και Επικοινωνιών (ICTs – Information & Communication Technologies), καθώς και των προοδευτικών υπηρεσιών προστιθέμενης αξίας, με αιχμή του δόρατος την ανάπτυξη του Διαδικτύου (Internet), επιδρά δραστικά σε πολλές πτυχές της σύγχρονης ζωής. Η διανομή και προσφορά προϊόντων και υπηρεσιών δεν εξαρτάται πλέον από φυσικούς περιορισμούς, όπως η θέση και ο χρόνος. Οι τεχνικοοικονομικές εξελίξεις οδήγησαν σε ένα περιβάλλον οπού η πρόσβαση σε πληροφορίες, υπηρεσίες, αλλά και αγαθά έγινε πιο εύκολη και οικονομική. Η πολλαπλασιαστική δράση των χαρακτηριστικών αυτών, γίνεται καθημερινά ολοένα και πιο εμφανής. Οι εταιρίες, κυρίως του ιδιωτικού τομέα, πολύ γρηγορά αναγνωρίσαν και εκμεταλλευτήκαν τις αναδυόμενες δυνατότητες ευκαιρίες. Η λεγομένη «ψηφιακή επανάσταση προσφέρει, μεταξύ άλλων, και σημαντικές ευκαιρίες βελτίωσης του επιπέδου των παρεχόμενων υπηρεσιών από το Δημόσιο Τομέα. Τα σύγχρονο περιβάλλον της τηλεπληροφορικής παρέχει αυξημένες δυνατότητες βέλτιστης προσαρμογής των παρεχόμενων υπηρεσιών στις ανάγκες των πολίτων. Οι πολίτες από τη μεριά τους αποκτούν τη δυνατότητα διαδραστικής επικοινωνίας με τη διοίκηση, γεγονός που τους επιτρέπει να επιλέγουν αυτοί το ποτέ, που και πως θα επικοινωνούν με αυτήν. Πολλές υπηρεσίες μπορούν πλέον να παρέχονται χρησιμοποιώντας «ηλεκτρονικά» αντί «παραδοσιακά» κανάλια. Παράλληλα, οι τεχνολογικές εξελίξεις δίνουν τη δυνατότητα και στην ιδιά τη Δημόσια Διοίκηση να αναθεωρήσει και να βελτιώσει πολλές από τις εσωτερικές λειτουργίες της. Ως αποτέλεσμα, σε όλες τις προηγμένες χώρες, η Δημόσια Διοίκηση προχώρα σε εκτενή χρήση των νέων τεχνολογιών και υπηρεσιών, για την υποστήριξη τόσο των εσωτερικών της λειτουργιών, όσο και της επικοινωνίας της με τους πολίτες. Από την πλευρά τους, οι πολίτες αναμένουν και αναζητούν από τη Δημόσια Διοίκηση, ένα πλήρες σύνολο υπηρεσιών πραγματικού χρόνου. Είναι χαρακτηριστική, τα τελευταία χρονιά, η διεθνής αύξηση των προγραμμάτων Ηλεκτρονικής Διακυβέρνησης, που αποσκοπούν στη δημιουργία ενός εξελιγμένου περιβάλλοντος Ηλεκτρονικής Δημόσιας Διοίκησης με ταυτόχρονη αντιμετώπιση των θεσμικών και κανονιστικών προβλημάτων. Στην περίπτωση της Ηλεκτρονικής Διακυβέρνησης, η Ελλάδα βρίσκεται στις τελευταίες θέσεις ανάμεσα στις ευρωπαϊκές χώρες. Συγκεκριμένα σύμφωνα με τον δείκτη Ψηφιακής Οικονομίας και Κοινωνίας (DESI), το 2019 η χώρα μας κατατάσσεται στη θέση 26 από τις 28 συνολικές χώρες, μόλις πάνω από τη Βουλγαρία και τη Ρουμανία. Πολλά τα βήματα επομένως που πρέπει να ακολουθήσει η Ελλάδα για να μπορέσει να προσεγγίσει το επίπεδο ηλεκτρονικής ωριμότητας των υπόλοιπων κρατών. Για αυτόν το λόγο, η ηλεκτρονική διακυβέρνηση αποτελεί ένα από τα μεγαλύτερα στοιχήματα της χώρας μας για το μέλλον.

description: Gossip algorithms are widely used in modern distributed systems, with applications ranging from sensor networks and peer-to-peer networks to mobile vehicle networks and social networks. A tremendous research effort has been devoted to analyzing and improving the asymptotic rate of convergence for gossip algorithms. In this work we study finite-time convergence of deterministic gossiping. We show that there exists a symmetric gossip algorithm that converges in finite time if and only if the number of network nodes is a power of two, while there always exists an asymmetric gossip algorithm with finite-time convergence, independent of the number of nodes. For $n=2^m$ nodes, we prove that a fastest convergence can be reached in $nm=n\log_2 n$ node updates via symmetric gossiping. On the other hand, under asymmetric gossip among $n=2^m+r$ nodes with $0\leq r<2^m$, it takes at least $mn+2r$ node updates for achieving finite-time convergence. It is also shown that the existence of finite-time convergent gossiping often imposes strong structural requirements on the underlying interaction graph. Finally, we apply our results to gossip algorithms in quantum networks, where the goal is to control the state of a quantum system via pairwise interactions. We show that finite-time convergence is never possible for such systems.

Next-to-Next-to-Leading-Order Charm-Quark Contribution to the CP Violation Parameter epsilon_K and Delta M_K

Year: 2011
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: The observables epsilon_K and Delta M_K play a prominent role in particle physics due to their sensitivity to new physics at short distances. To take advantage of this potential, a firm theoretical prediction of the standard-model background is essential. The charm-quark contribution is a major source of theoretical uncertainty. We address this issue by performing a next-to-next-to-leading-order (NNLO) QCD analysis of the charm-quark contribution eta_cc to the effective |Delta S|=2 Hamiltonian in the standard model. We find a large positive shift of 36%, leading to eta_cc = 1.87(76). This result might cast doubt on the validity of the perturbative expansion; we mention possible solutions. Finally, we give an updated value of the standard-model prediction for |epsilon_K| = 1.81(28) x 10^-3 and Delta M_K(SD) = 3.1(1.2) x 10^-15 GeV.

am Jagdschloss Clemenswerth in Sögel/Niedersachsen durchgeführt wird. Dabei werden
sowohl allgemeine Grundsätze von Langzeituntersuchungen entwickelt als auch deren praxisorientierte
Anwendung getestet. Bis dato existieren keine allgemeinen Grundlagen für ein Monitoring in der Denkmalpflege. Durch die Recherche und Evaluation verschiedener Ansätze konnten viele Ideen für die Langzeituntersuchungen von Steinobjekten entwickelt und adaptiert werden. Zu den betrachteten Ansätzen gehören neben wenigen Beispielen aus der Denkmalpflege selbst unter anderem auch Konzepte aus der Bauwerksüberprüfung, der Gebäudeinspektion und dem Qualitätsmanagement. Die daraus gewonnenen Ergebnisse flossen in ein allgemeines Monitoringkonzept für Steinobjekte ein. Anschließend wurde dieses mit einfachen Methoden erfolgreich auf die Steinskulpturen in Clemenswerth angewandt. Durch die praktische Umsetzung konnten einfache aber effektive Methoden für das weitere Vorgehen in Clemenswerth gewonnen werden. Die Ergebnisse dieser Arbeit können auf andere Objekte übertragen werden und eine Grundlage für zukünftige denkmalpflegerische Langzeituntersuchungen bieten.

description: In the fifth of our series about Oxford and the Great War, this short video considers the attitude of serving officers and officers-to-be towards the conflict: how much has life changed for the rank-and-file soldier, and how much stays the same? What motivates soldiers to take the risks they do?

The Oxford University Officers' Training Corps, founded in 1642, has trained and sent officers from the university to nearly every war or conflict over the last three decades. During the First World War, nearly all undergraduates who joined up would pass through the OTC for training on their way to the front. This included JRR Tolkien, CS Lewis, Noel Chavasse and Lawrence of Arabia. More than 2000 student officers never returned. Today the OTC provides leadership training and character building for students from Oxford and other local universities, and forms an important part of the military fabric of Oxford University.

description: A relation between O(n) lattice spin models and Ising models defined on the same lattice was recently put forward [L. Casetti, C. Nardini, and R. Nerattini, Phys. Rev. Lett. 106, 057208 (2011)]. Such a relation, inspired by an energy landscape analysis, implies that the density of states of an O(n) spin model on a lattice can be effectively approximated, at least close to the phase transition, in terms of the density of states of an Ising model defined on the same lattice and with the same interactions. In the present paper we show that such a relation exactly holds, albeit in a slightly modified form, in the special cases of the mean-field XY model and of the one-dimensional XY model. We also discuss the possible consequences of this result for the general case.
Two ways to the top : evidence that dominance and prestige are distinct yet viable avenues to social rank
Creators: name: Cheng, Joey T.
Publisher: name: University of British Columbia
Year: 2013

description: The pursuit of social rank is a recurrent and pervasive challenge faced by individuals in all human societies. Yet, the precise means through which individuals compete for social standing remains unclear. Chapters 2 and 3 addressed this question and examined the impact of two fundamental strategies—Dominance (the use of force and intimidation to induce fear) and Prestige (the sharing of expertise or know-how to gain respect)—on the attainment of social rank, among a group of individuals who interacted over a collaborative group task. Consistent with this theoretical framework, the adoption of either a Dominance or Prestige strategy promoted perceptions of greater influence as rated by both group members and outside observers, higher levels of actual impact over the group’s decision-making (Chapter 2), and increased visual attention from observers whose gaze was monitored with an eye-tracking device (Chapter 3). Subsequent studies explored the ethological underpinnings of these rank-attaining strategies by examining the verbal styles and nonverbal behaviors displayed by Dominant and Prestigious individuals during the group interactions. Detailed behavioral coding revealed that whereas Dominance was signaled through intimidating and self-entitling verbal styles and spatially expansive and aggressive postural displays, Prestige was signaled through socially attractive and self-deprecating verbal styles and confidence-signaling nonverbal movements (Chapters 4-5). Furthermore, Dominant individuals signaled their formidability by lowering their vocal pitch during the initial minutes of the group interaction (Chapter 6). In contrast, Prestige was not systematically associated with alterations in pitch. Collectively, these studies demonstrate that Dominance and Prestige are independent yet both viable strategies for ascending the social hierarchy, and are each underpinned by distinct, theoretically predictable patterns of verbal styles and nonverbal behaviors.

description: Discorhabdella Dendy, 1924
 Diagnosis. Encrusting poecilosclerids characterized by a category of small acanthostyles with a globate tyle and a short shaft with spines concentrated towards the end, along with a category of large choanosomal tylostyles with tuberose tyles, and a category of small ectosomal subtylostyles. A single category of anchorate-unguifer - ate isochelae occurs in all species, except one of the new species described herein. Microxeas and sigmas may also occur, depending upon species.
 Remarks. The acanthostyle of Discorhabdella is highly characteristic in possessing a globate tyle, the hypertrophy of which is so important in some species that the spicule resembles an aster, and is termed a`pseudoastrose acanthostyle’ (Dendy, 1924). SEM observations reveal axial canals within the spines of the globate tyle, indicating that the presumed spines are actually actines and suggesting that these peculiar acanthostyles have evolved from a polyaxonid spicule, an ancestor most likely shared with the aster-like desmas of Crambe (Uriz and Maldonado, 1995; Maldonado and Uriz, 1996). The fact that Crambe and Discorhabdella share virtually identical spicule complement except for the aster-like desmas and the pseudoastrose acanthostyles is also consistent with the idea of aster-like desmas and pseudoastrose acanthostyle s being homologous spicules. The alternative hypothesi s that the pseudoastrose acanthostyles would not be non-polyaxonid in origin, but derived from regular diactinal acanthostyles is unlikely. From such an alternative view, the presence of axial canals in the aster-like tyles of Discorhabdella cannot be explained in agreement with the traditional actinal theory that distinguished between actines and spines in the spicules on the basis of the presence / absence of axial canals within the structure (Sollas, 1888; Dendy, 1921b, 1926). Furthermore, if aster-like desmas and pseudoastrose acanthostyles are considered non-homologous, the enormous similarity between Crambe and Discorhabdella in composition, structure and arrangement of the remaining spicule set would have to be explained by evolutionary convergence. Such a process is clearly unrealistic in probabilistic terms, given the large number of skeletal traits and micro-traits that should have converged (e.g. pattern of axial canals, spicule micro-ornamentation, spicule sizes and arrangement, etc.). It is also unsupported from any anatomic evidence.

Semi-Parametric Drift and Diffusion Estimation for Multiscale Diffusions

description: We consider the problem of statistical inference for the effective dynamics of multiscale diffusion processes with (at least) two widely separated characteristic time scales. More precisely, we seek to determine parameters in the effective equation describing the dynamics on the longer diffusive time scale, i.e. in a homogenization framework. We examine the case where both the drift and the diffusion coefficients in the effective dynamics are space-dependent and depend on multiple unknown parameters. It is known that classical estimators, such as Maximum Likelihood and Quadratic Variation of the Path Estimators, fail to obtain reasonable estimates for parameters in the effective dynamics when based on observations of the underlying multiscale diffusion. We propose a novel algorithm for estimating both the drift and diffusion coefficients in the effective dynamics based on a semi-parametric framework. We demonstrate by means of extensive numerical simulations of a number of selected examples that the algorithm performs well when applied to data from a multiscale diffusion. These examples also illustrate that the algorithm can be used effectively to obtain accurate and unbiased estimates.

description: In large cities the CBD area is a hustling, bustling area filled with activity from 8:00 a.m. to 5:00 p.m. After 5:00 p.m. the city's CBD area is usually dead. People working in the CBD leave the office, fighting five-o'clock traffic, to get to their residences in the suburbs. People working in CBD's generally don't live in the CBD due to lack of, or inadequate, housing. There is not a total solution to every problem, but mixed-use projects have been a concept to lessen the problem of lack of life in CBDs after 5:00. The specific mix of uses may vary, as may the overall project scale. The concept, however, remains the same; combining a range of uses into a single development which allows them to mutua11y support one another. This program consists of a mixture of residence, office space and retail space. The project is located in the CBD area of Austin, Texas. (See Figures B:, C, D.) The city supports this type of project to revitalize downtown. Ther3 is a lack of retail and residential space in the CBD. The site is appropriate for this type of project. Town Lake, a thriving outdoor community area, is adjacent to the site. The site is also near to many entertainment and cultural centers located mostly on 6th Street. The structure's height limit is 120 feet, due to Town Lake zoning to keep Town Lake in perspective. The site consists of 3^, blocks (one block to be designated for a new City Hall to be designed by others). This project will consist of 400,000 sf residential space, 300,000 sf office space, 100,000 sf retail space. The project will consist of separate buildings that can be connected with pedestrian bridges.
Estimation of integrated volatility of volatility with applications to goodness-of-fit testing

Subjects: subject: Statistics Theory (math.ST)

description: In this paper, we are concerned with nonparametric inference on the volatility of volatility process in stochastic volatility models. We construct several estimators for its integrated version in a high-frequency setting, all based on increments of spot volatility estimators. Some of those are positive by construction, others are bias corrected in order to attain the optimal rate $n^{-1/4}$. Associated central limit theorems are proven which can be widely used in practice, as they are the key to essentially all tools in model validation for stochastic volatility models. As an illustration we give a brief idea on a goodness-of-fit test in order to check for a certain parametric form of volatility of volatility.

description: Based on niche theory, closely related and morphologically similar species are not predicted to coexist due to overlap in resource and habitat use. Local assemblages of bats often contain cryptic taxa, which co-occur despite notable similarities in morphology and ecology. We measured in two different habitat types on Madagascar levels of stable carbon and nitrogen isotopes in hair (n = 103) and faeces (n = 57) of cryptic Vespertilionidae taxa to indirectly examine whether fine-grained trophic niche differentiation explains their coexistence. In the dry deciduous forest (Kirindy), six sympatric species ranged over 6.0% in delta N-15, i.e. two trophic levels, and 4.2% in delta C-13 with a community mean of 11.3% in delta N-15 and - 21.0% in delta C-13. In the mesic forest (Antsahabe), three sympatric species ranged over one trophic level (delta N-15: 2.4%, delta C-13: 1.0%) with a community mean of 8.0% delta N-15 and - 21.7% in delta C-13. Multivariate analyses and residual permutation of Euclidian distances in delta C-13- delta N-15 bi-plots revealed in both communities distinct stable isotope signatures and species separation for the hair samples among coexisting Vespertilionidae. Intraspecific variation in faecal and hair stable isotopes did not indicate that seasonal migration might relax competition and thereby facilitate the local co-occurrence of sympatric taxa.

description: Im Rahmen dieser Praxisforschung wird die Konzeption, Durchführung und Evaluation eines sprach- und kommunikationsunterstützenden Tanzprojekts dargestellt, welches mit sechs- bis achtjährigen Kindern einer ersten Klasse der Sprachheilschule in Form einer fallbezogenen Gruppentherapie umgesetzt wurde. Das Entwicklungsprojekt basiert auf Übungen aus dem Förderbereich der basalen exekutiven Funktionen und erforscht durch Literaturanalyse deren Zusammenhang mit Sprache und Bewegung.Unter Einbezug des Projektmanagements, der Rhythmik und Psychomotorik wird das Hauptziel einer bewegten Intervention verfolgt, welche Übungen aus dem Bereich der exekutiven Funktionen nutzt, um die Sprachentwicklung positiv zu beeinflussen.Fortlaufend und abschliessend findet eine Evaluation des Projekts statt. Dabei wird hauptsächlich die Perspektive der Klassenlehrperson in Form eines halbstrukturierten Interviews und diejenige der teilnehmenden Kinder mit Hilfe eines teilstandardisierten Fragebogens ermittelt. Für alle Befragten war das Projekt mit Freude verbunden und es konnten Fortschritte im Bereich der exekutiven Funktionen erzielt werden. Dabei wird hauptsächlich die Weiterentwicklung der inhibitorischen Fähigkeiten (Bedürfnisaufschub, Impulskontrolle, zuhören) erwähnt. Jedoch hat auch das Arbeitsgedächtnis durch das Erinnern an Bewegungsabfolgen und die kognitive Flexibilität durch das Eingehen auf Neues profitiert. Ein Einfluss auf die Sprachentwicklung ist nach Abschluss des Projekts noch nicht sichtbar, liesse sich aber womöglich durch eine längere Intervention dieser Art realisieren.
Search for pair-produced heavy quarks decaying to Wq in the two-lepton channel at sqrt(s) = 7 TeV with the ATLAS detector

description: A search is presented for heavy-quark pair production (QQbar) under the decay hypothesis QQbar to WqWq with q = u,d,c,s,b. The search is performed with 1.04 fb^-1 of integrated luminosity from pp collisions at sqrt(s) = 7 TeV collected by the ATLAS detector at the CERN LHC. Dilepton final states are selected, requiring large missing transverse momentum and at least two jets. Mass reconstruction of heavy quark candidates is performed by assuming that the W boson decay products are nearly collinear. The data are in agreement with Standard Model expectations; a heavy quark with mass less than 350 GeV is excluded at 95% confidence level.

Design of Optimal Sparse Feedback Gains via the Alternating Direction Method of Multipliers

description: We design sparse and block sparse feedback gains that minimize the variance amplification (i.e., the $H_2$ norm) of distributed systems. Our approach consists of two steps. First, we identify sparsity patterns of feedback gains by incorporating sparsity-promoting penalty functions into the optimal control problem, where the added terms penalize the number of communication links in the distributed controller. Second, we optimize feedback gains subject to structural constraints determined by the identified sparsity patterns. In the first step, the sparsity structure of feedback gains is identified using the alternating direction method of multipliers, which is a powerful algorithm well-suited to large optimization problems. This method alternates between promoting the sparsity of the controller and optimizing the closed-loop performance, which allows us to exploit the structure of the corresponding objective functions. In particular, we take advantage of the separability of the sparsity-promoting penalty functions to decompose the minimization problem into sub-problems that can be solved analytically. Several examples are provided to illustrate the effectiveness of the developed approach.
