description: Loss of power and clear description of treatment differences are key issues in designing and analyzing a clinical trial where non-proportional hazard is a possibility. A log-rank test may be very inefficient and interpretation of the hazard ratio estimated using Cox regression is potentially problematic. In this case, the current ICH E9 (R1) addendum would suggest designing a trial with a clinically relevant estimand, e.g., expected life gain. This approach considers appropriate analysis methods for supporting the chosen estimand. However, such an approach is case specific and may suffer lack of power for important choices of the underlying alternate hypothesis distribution. On the other hand, there may be a desire to have robust power under different deviations from proportional hazards. Also, we would contend that no single number adequately describes treatment effect under non-proportional hazards scenarios. The cross-pharma working group has proposed a combination test to provide robust power under a variety of alternative hypotheses. These can be specified for primary analysis at the design stage and methods appropriately accounting for combination test correlations are efficient for a variety of scenarios. We have provided design and analysis considerations based on a combination test under different non-proportional hazard types and present a straw man proposal for practitioners. The proposals are illustrated with real life example and simulation.

description: In February 2009, the European Union‟s (EU) Directive for the inclusion of international aviation into the EU Emissions Trading Scheme (EU-ETS) for CO2-emissions came into force. From 2012 onwards, the EU-ETS will cover virtually all flights departing or arriving in the EU. The initial allo-cation of emission allowances to airlines will be based on a benchmark which is calculated by divid-ing the 2004-2006 CO2-emissions by the transport performance of the year 2010. This paper de-scribes an empirical simulation model for the impact of the EU-ETS. Current and future CO2-emissions and transport performance data of European aviation will be estimated. Furthermore, the economic effects of the upcoming EU-ETS on the aviation sector in total, on selected groups of air-lines and on the administering states will be analysed and discussed. It can be shown that certain airline groups and administering EU States will be affected very differently by the new EU legislation.

description: This paper determines the deadweight loss of operating and capital subsidies offered US public transit systems by extending previous research by Tullock (1997). It develops a method for calculating deadweight loss and using 2006 data for 227 single mode bus transit systems it estimates cost and share equations to obtain the coefficients needed to calculate this loss. It finds that deadweight loss from the subsidies is 6.83% of total cost or $0.861 million on the average and that operating subsidy accounts for $0.780 million of it while capital subsidy’s share is $0.0503 million. A further decomposition of the deadweight loss among its sources using regression shows that the incentive tier of the federal operating subsidy, federal labor protection (Section 13(c)), fleet size, and the number of maintenance facilities owned are positively associated with it while leasing instead of owning maintenance facilities and absence of dedicated funding sources are negatively associated with it.
Signatures of octupole shape phase transitions in radioactive nuclei

subject: FOS: Physical sciences

description: We analyze the octupole deformations and the related collective excitations in medium-heavy and heavy nuclei based on the microscopic framework of the nuclear energy density functional theory. Constrained self-consistent mean-field calculation with a given energy density functional is performed to provide for each nucleus a potential energy surface with axial quadrupole and octupole shape degrees of freedom. Spectroscopic properties are computed by means of the interacting-boson Hamiltonian, which is determined by mapping the fermionic potential energy surface onto the bosonic counterpart. The overall systematics of the calculated spectroscopic observables exhibit phase transitional behaviors between stable octupole deformation and octupole vibration characteristic of the octupole-soft potential within the set of nuclei in light actinide and rare-earth regions, Th, Ra, Sm, Gd, and Ba isotopes, where octupole shapes are most likely to occur.

description: Metropolitan areas are facing increasing congestion but financial resources to provide new or expanded transportation infrastructure will be limited in the future. Moreover, environmental constraints limit expansion of the highway footprint in urban travel corridors. This paper assesses a strategy to alleviate recurring congestion on metropolitan highway systems by adding “dynamic” capacity during peak periods using shoulders as travel lanes, along with variable peak-period user charges levied on all lanes to manage demand and pay for the capacity improvements. It presents an analysis of the traffic, delay, fuel consumption, CO2 emissions, and cost and revenue impacts. The paper then discusses various technical and public acceptance issues with regard to the concept, and how these issues might be addressed.

description: We propose and evaluate transformer-based acoustic models (AMs) for hybrid speech recognition. Several modeling choices are discussed in this work, including various positional embedding methods and an iterated loss to enable training deep transformers. We also present a preliminary study of using limited right context in transformer models, which makes it possible for streaming applications. We demonstrate that on the widely used Librispeech benchmark, our transformer-based AM outperforms the best published hybrid result by 19% to 26% relative when the standard n-gram language model (LM) is used. Combined with neural network LM for rescoring, our proposed approach achieves state-of-the-art results on Librispeech. Our findings are also confirmed on a much larger internal dataset.

NGC 3310, a galaxy merger?

description: The HI structure and kinematics of the peculiar starburst galaxy NGC 3310 (Arp 217, UGC 5786) are discussed. New evidence bearing on the origin of the starburst is presented. The bulk of HI coincides with the bright optical disk and shows differential rotation. Its velocity dispersion is, however, unusually large for a spiral galaxy (up to 40 km/s), suggesting that the disk is highly perturbed as already indicated by optical emission line spectroscopy. There are, in addition, two prominent HI tails, one extending to the north-west and the other, somewhat patchy, to the south. These HI tails, the perturbed kinematics and the peculiar optical morphology strongly suggest a recent merger between two gas-rich galaxies. This seems to have been a major merger in which most of the gas in the inner parts has been preserved in neutral atomic form and either one of the progenitor disks has survived or a new disk has formed.

description: This paper presents optical UBVRI broadband photo-polarimetry of the EXPORT sample obtained at the 2.5m Nordic Optical Telescope. The database consists of multi-epoch photo-polarimetry of 68 pre-main-sequence and main-sequence stars. An investigation of the polarization variability indicates that 22 objects are variable at the 3sigma level in our data. All these objects are pre-main sequence stars, consisting of both T Tauri and Herbig Ae/Be objects while the main sequence, Vega type and post-T Tauri type objects are not variable. The polarization properties of the variable sources are mostly indicative of the UXOR-type behaviour; the objects show highest polarization when the brightness is at minimum. We add seven new objects to the class of UXOR variables (BH Cep, VX Cas, DK Tau, HK Ori, LkHa 234, KK Oph and RY Ori). The main reason for their discovery is the fact that our data-set is the largest in its kind, indicating that many more young UXOR-type pre-main sequence stars remain to be discovered. The set of Vega-like systems has been investigated for the presence of intrinsic polarization. As they lack variability, this was done using indirect methods, and apart from the known case of BD +31.643, the following stars were found to be strong candidates to exhibit polarization due to the presence of circumstellar disks: 51 Oph, BD +31.643C, HD 58647 and HD 233517.

description: The collaborative knowledge graphs such as Wikidata excessively rely on the crowd to author the information. Since the crowd is not bound to a standard protocol for assigning entity titles, the knowledge graph is populated by non-standard, noisy, long or even sometimes awkward titles. The issue of long, implicit, and nonstandard entity representations is a challenge in Entity Linking (EL) approaches for gaining high precision and recall. Underlying KG, in general, is the source of target entities for EL approaches, however, it often contains other relevant information, such as aliases of entities (e.g., Obama and Barack Hussein Obama are aliases for the entity Barack Obama). EL models usually ignore such readily available entity attributes. In this paper, we examine the role of knowledge graph context on an attentive neural network approach for entity linking on Wikidata. Our approach contributes by exploiting the sufficient context from a KG as a source of background knowledge, which is then fed into the neural network. This approach demonstrates merit to address challenges associated with entity titles (multi-word, long, implicit, case-sensitive). Our experimental study shows approx 8% improvements over the baseline approach, and significantly outperform an end to end approach for Wikidata entity linking.

description: We consider the network constraints on the bounds of the assortativity coefficient, which measures the tendency of nodes with the same attribute values to be interconnected. The assortativity coefficient is the Pearson's correlation coefficient of node attribute values across network edges and ranges between -1 and 1. We focus here on the assortativity of binary node attributes and show that properties of the network, such as degree distribution and the number of nodes with each attribute value place constraints upon the attainable values of the assortativity coefficient. We explore the assortativity in three different spaces, that is, ensembles of graph configurations and node-attribute assignments that are valid for a given set of network constraints. We provide means for obtaining bounds on the extremal values of assortativity for each of these spaces. Finally, we demonstrate that under certain conditions the network constraints severely limit the maximum and minimum values of assortativity, which may present issues in how we interpret the assortativity coefficient.

description: The mirror mode evolving in collisionless magnetised high-temperature thermally anisotropic plasmas is shown to develop an interesting macro-state. Starting as a classical zero frequency ion fluid instability it saturates quasi-linearly at very low magnetic level, while forming elongated magnetic bubbles which trap the electron component to perform an adiabatic bounce motion along the magnetic field. {Further evolution of the mirror mode towards a stationary state is determined by the bouncing trapped electrons which interact with the thermal level of ion sound waves, generate attractive wake potentials which give rise to formation of electron pairs in the lowest-energy singlet state of two combined electrons. Pairing takes preferentially place near the bounce-mirror points where the pairs become spatially locked with all their energy in the gyration. The resulting large anisotropy of pairs enters the mirror growth rate in the quasi-linearly stable mirror mode. It breaks the quasilinear stability and causes further growth. Pressure balance is either restored by dissipation of the pairs and their anisotropy or inflow of plasma from the environment. In the first case new pairs will continuously form until equilibrium is reached. In the final state the fraction of pairs can be estimated. This process is open to experimental verification. To our knowledge it is the only process where in high temperature plasma pairing may occur and has an important observable macroscopic effect: breaking the quasilinear limit and generation of localised diamagnetism.}

description: La vulnérabilité intrinsèque des piétons sur la route et l’utilisation croissante, par la population, des téléphones portables et autres objets connectés font de la distraction des piétons un enjeu croissant de sécurité routière. Afin de développer la connaissance à ce sujet, l’Agence wallonne pour la Sécurité routière (AWSR) a interrogé, en août 2018, 1 000 Wallons âgés de minimum 16 ans sur leur comportement et leurs attitudes en matière de distraction en tant que piétons, en particulier lorsqu’ils traversent la route. Basée sur la théorie du comportement planifié, cette enquête a pour objectifs de mesurer la prévalence de la distraction parmi les piétons wallons et d’identifier les facteurs pouvant influencer leur distraction en cours de traversée. L’étude s’est concentrée sur deux sources de distraction principales : l’usage d’un téléphone portable et l’écoute de musique (à travers un casque ou des écouteurs) en cours de traversée de la route. Les analyses réalisées (régressions logistiques) ont identifié certaines caractéristiques individuelles influençant la distraction du piéton en cours de traversée. L’utilisation du téléphone et l’écoute de musique en traversant diminuent avec l’âge et sont plus fréquentes parmi les piétons présentant une aversion au risque plus faible. Inversement, l’addiction au téléphone et l’adoption d’autres comportements à risque en tant que piéton sont, elles, positivement corrélées à ces comportements distrayants.

description: The stable economic conditions are fundamental for the sustainable development of transport. For this reason the contribution of transport, respectively road transport, to GDP per year and to the gross value added (GVA) are the main indicators for assessment of economic sustainability of road transport presented in the paper. Along with the indices such as share of transport in GDP, the consumers’ expenditure on transport, the volume of freight and passenger transport by modes, share of road transport, traffic volumes and transport infrastructure capacity, the analysis provides a base for the assessment of the economic sustainability of road transport in Bulgaria. Comparisons with the relative indicators in the EU-27 are made in order to clarify the Bulgarian position on the European market. Furthermore, the level of infrastructure provision is evaluated through the analysis of investments on new infrastructures. Thus the long term sustainability of road transport is assessed too and some opportunities for the future development based on an economic sustainability are outlined. As a result of the analysis the opportunities for improving transport services and for decrease in road transport costs in Bulgaria have been revealed.

description: We discuss semiclassical quantization of closed superstrings in AdS_5 x S^5. We consider two basic examples: point-like string boosted along large circle of S^5 and folded string rotating in AdS_5. In the first case we clarify the general structure of the sigma model perturbation theory for the energy of string states beyond the leading 1-loop order (related to the plane-wave limit). In the second case we argue that the large spin limit of the expression for the ground-state energy (i.e. for the dimension of the corresponding minimal twist gauge theory operator) has the form S + f(λ) \ln S to all orders in α' ~ λ^{-1/2} expansion, in agreement with the AdS/CFT duality. We also suggest an extension of the semiclassical approach to near-conformal (near-AdS) cases on the example of the fractional D3-brane on conifold background.

title: Prozessmodell für die bedarfsgerechte Bestandsentwicklung des Portfolios von Wohnungsbaugenossenschaften
Creators: name: Ruhl, Sandra
Publisher: name: UNSPECIFIED
Year: 2025

description: Wohnen stellt ein Grundbedürfnis sowie ein Grundrecht der Menschheit dar. In Deutschland werden von den rund 43,1 Mio. Wohnungen mehr als die Hälfte (53,49 % der Wohnungen) vermietet. Der Mietwohnungsmarkt in Deutschland ist daher von großer Bedeutung. Insbesondere in den urbanen Regionen in Deutschland ist derzeit ein Anstieg der Nachfrage nach Wohnraum erkennbar. Demzufolge wird es für einkommensschwache Haushalte und Familien immer schwerer bedarfsgerechten, also bezahlbaren Wohnraum mit einer bedarfsgerechten Nutzungsqualität insbesondere in den urbanen Regionen in Deutschland zu finden.
Wohnungsbaugenossenschaften zählen zu den professionell-gewerblichen Anbietern und agieren als Not-for-Profit Unternehmen. Sie sind aufgrund ihrer Satzung bestrebt, ihren Mitgliedern bedarfsgerechten sowie bezahlbaren Wohnraum zur Verfügung zu stellen. Derzeit stehen die Wohnungsbaugenossenschaften vor der Herausforderung, ihr heterogenes Immobilienportfolio gemäß den Bedürfnissen der Mitglieder zu sichern und fortzuentwickeln. Denn im Rahmen der Bestandsentwicklung sind neben den technischen, wirtschaftlichen und ökologischen Anforderungen insbesondere die sozialen Ziele und Werte zu berücksichtigen.
Im Rahmen der vorliegenden Dissertation wurde ein Prozessmodell zur bedarfsgerechten Bestandsentwicklung des Portfolios von Wohnungsbaugenossenschaften entwickelt. Das Prozessmodell besteht aus drei Teilprozessstrukturelementen: Nutzeranforderungen, Bestandsentwicklungsmanagement und Bestandsentwicklungskosten. Im Kontext der Nutzeranforderungen sind Experteninterviews und Mitgliederbefragungen durchzuführen und die Kano-Methode ist anzuwenden. Im Rahmen des Bestandsentwicklungsmanagement ist als strategisches Instrument das von der Verfasserin entwickelte genossenschaftliche Portfoliomodell anzuwenden. Gegenstand der Bestandsentwicklungskosten ist die Bestimmung einer wirtschaftlichen Strategie zur langfristigen Unterhaltung der Immobilien unter Anwendung eines mathematischen Modells. Dieses Modell basiert auf der Graphentheorie.
Das entwickelte Prozessmodell unterstützt die Wohnungsbaugenossenschaften im multikriteriellen Entscheidungsprozess, eine transparente und nachvollziehbare Entscheidung über die Fortentwicklung des Portfolios festzulegen. Durch Anwendung des Prozessmodells wird sichergestellt, dass das Portfolio bedarfsgerecht, qualitätsvoll und betriebswirtschaftlich fortentwickelt wird.

description: In 2008, the U.S. witnessed 9% reduction in traffic fatalities across the nation. In Virginia, 205 less persons were killed in traffic crashes in 2008 than in 2007, which is an unprecedented one-year decline since 1950, following by 170 reduction in 1974 allegedly attributable to oil crisis. Part of the reduction can probably be ascribed to continuous efforts for safety improvements in education, law, policy, technology, and vehicle and road design. However, some portion of the reduction may be attributable to changes in economic conditions in late 2007 and 2008. In this regard, this study attempted to find contributing factors to the 2008 reduction in traffic fatalities using Virginia data, and economic indicators (e.g., unemployment rate), crash exposures (e.g., vehicle miles traveled), and other factors (e.g., beer consumption) were attempted to relate to changes in fatalities using a time-series model. Changes in total employment number and unemployment rate were determined to be the best contributing factors for changes in annual traffic fatalities. However, only the unemployment rate was able to explain a portion of the reduction in 2008, 27%.

Simultaneously, the power of networks is growing. In technology, science and civil society, social networks are becoming a way to uncover the hidden architecture of complexity and unlock people’s capacity to think and act in different ways (Christakis and Fowler 2011).

description: The classical T Tauri star RW Aur A is an irregular variable with a large amplitude in all photometric bands. In an extended series of photometric data we found small-amplitude periodic variations in the blue colours of the star, with a period of 2.64 days. The period was relatively stable over several years. The amplitude of the periodic signal is 0.21 mag in U-V, 0.07 mag in B-V, and about 0.02 mag in V-R and V-I. No periodicity was found in the V magnitude. The relevance of this photometric period to the recently discovered periodicity in spectral features of the star is discussed, and the hypothesis of a hot spot is critically considered.

description: Since 1992, traffic signals in Oakland County and a portion of Macomb and Wayne Counties of Michigan have been converted to the Sydney Coordinated Adaptive Traffic System (SCATS). County traffic engineers have been adjusting various SCATS parameters to improve its effectiveness in terms of delay, traffic flow, queue length, and crash and injury occurrences. In 2008, a study was conducted to evaluate the performance of the SCATS system on M-59, between Pontiac Lake East to Pontiac lake West in Waterford Township, Michigan, in terms of delay, flow, queue length and Fuel consumption and Emission. As a part of this study various performance parameters of SCATS system were compared with the Pre-timed signal system. Performance of the SCATS system was found to be superior for several of the performance measures during each Peak period. When compared to Pre-Timed signal, installation and maintenance cost of SCATS system is almost two times greater. Therefore, there is a need to determine the added related benefits of SCATS system. In this context, determination of crash benefit of SCATS can play a significant role. If we can combine congestion and crash related benefits, then it is most likely combined benefits will overweigh the cost. Crash data from 1999 to 2008 of two corridors, one controlled by the SCATS and other by the Pre-timed signal system were examined to determine the effectiveness of SCATS system. In order to evaluate the effectiveness of SCATS signal system, intersections as well as segment crash data before and after the installation of SCATS signal were compared. In addition, a series of statistical tests were performed to compare safety performance of SCATS and pre-timed signal systems. It was observed that there was shift in severity types A and B to C, which is noteworthy. However, statistical tests were not able to identify any difference of significant at 95 percent confidence level. Finally, cost related information for both SCATS as well as pre-timed was also computed and compared.

Projected Newton Method for noise constrained Tikhonov regularization

description: Tikhonov regularization is a popular approach to obtain a meaningful solution for ill-conditioned linear least squares problems. A relatively simple way of choosing a good regularization parameter is given by Morozov's discrepancy principle. However, most approaches require the solution of the Tikhonov problem for many different values of the regularization parameter, which is computationally demanding for large scale problems. We propose a new and efficient algorithm which simultaneously solves the Tikhonov problem and finds the corresponding regularization parameter such that the discrepancy principle is satisfied. We achieve this by formulating the problem as a nonlinear system of equations and solving this system using a line search method. We obtain a good search direction by projecting the problem onto a low dimensional Krylov subspace and computing the Newton direction for the projected problem. This projected Newton direction, which is significantly less computationally expensive to calculate than the true Newton direction, is then combined with a backtracking line search to obtain a globally convergent algorithm, which we refer to as the Projected Newton method. We prove convergence of the algorithm and illustrate the improved performance over current state-of-the-art solvers with some numerical experiments.

description: The low price elasticity of gasoline demand has been shown in different studies. People‟s weak perception about how much they spend on fuel is considered as an important reason. The purpose of this study is to show how information about gas consumption may change people‟s behavior. Congestion pricing has been successful in terms of reducing demand and even changing people‟s decisions. People perceive this pricing as out of pocket cost and take that into account while making decisions. A similar procedure can be implemented for fuel costs. On-line information from transportation networks can be used to estimate the gas consumption cost for each route, using on-road banners or GPS devices. The idea is that as a result of becoming informed about their gas consumption increase when entering traffic congestion, people may take an alternative route or decide not to travel at all. Although it is not possible to estimate the exact change in the price elasticity of gas by introducing this method directly, this study tries to estimate the proper gas price and its effects on people‟s route choice behavior and compare gas consumption information to congestion pricing scheme. The results from a small network showed that providing this information can improve people‟s behavior in terms of route choice. Keywords- Congestion pricing, Gasoline consumption, Route change.
Solitons for the fuzzy sphere from matrix model

description: Recently we have introduced a matrix model depending on two coupling constants $g^2$ and $λ$, which contains the fuzzy sphere as a background; to obtain the classical limit $g^2$ must depend on $N$ in a precise way. In this paper we show how to obtain the classical solitons of the $N \to \infty$ limit imposing the development $λ= \half + \frac{λ_0}{N}$; as a consequence at finite $N$ one obtains a noncommutative version of the solitons for the fuzzy sphere.

The leading jet transverse momentum in inclusive jet production and with a loose jet veto

description: We study the transverse momentum of the leading jet in the limit where the jet radius is small, $R\ll 1$. We introduce the leading-jet function to calculate this cross section for an inclusive jet sample, and the subleading-jet function when a loose veto on additional jets is imposed, i.e. $p_{T,J} \gtrsim p_T^{\rm veto}$. These jet functions are calculated at next-to-leading order in QCD and the resummation of jet radius logarithms is explored. We present phenomenological results for Higgs + 1 jet production, for both the jet and Higgs transverse momentum distribution. We find that, while the $R \ll 1$ limit of the cross section provides a good description of the full NLO result, even for values as large as $R=0.8$, simply retaining the leading logarithm at this order does not. Indeed, the NLO contribution to the hard function and, to a lesser extent, non-logarithmic corrections to the jet function are sizable and must be included to obtain the correct cross section. In the inclusive cross section we find that the $α_s^2 \ln^2R$ corrections are several precent, while in exclusive cross sections at large $p_{T,J}$ and small $R$ they can reach 20%. However, it is not clear how important the resummation of these logarithms is, given the presence of other large corrections at NNLO.

description: We present a scenario to explain the lithium-rich phase which occurs on the red giant branch at the so-called bump in the luminosity function. The high transport coefficients required to enhance the surface lithium abundance are obtained in the framework of rotation-induced mixing thanks to the impulse of the important nuclear energy released in a lithium burning shell. Under certain conditions a lithium flash is triggered off. The enhanced mass loss rate due to the temporary increase of the stellar luminosity naturally accounts for a dust shell formation.

Meridional flow and differential rotation by gravity darkening in fast rotating solar-type stars

description: An explanation is presented for the rather strong total surface differential rotation of the observed very young solar-type stars like AB Dor and PZ Tel. Due to its rapid rotation a nonuniform energy flux leaves the stellar core so that the outer convection zone is nonuniformly heated from below. Due to this `gravity darkening' of the equator a meridional flow is created flowing equatorwards at the surface and thus accelerating the equatorial rotation. The effect linearly grows with the normalized pole-equator difference, ε, of the heat-flux at the bottom of the convection zone. A rotation rate of about 9 h leads to ε=0.1 for a solar-type star. In this case the resulting equator-pole differences of the angular velocity at the stellar surface, δΩ, varies from unobservable 0.005/day to the (desired) value of 0.03 day$^{-1}$ when the dimensionless diffusivity factors $c_ν$ and c_χvary between 1 and 0.1 (standard value c_ν\simeq c_χ\simeq 0.3, see Table 1.) In all cases the related temperature differences between pole and equator at the surface are unobservably small. The (clockwise) meridional circulation which we obtain flows opposite to the (counterclockwise) circulation appearing as a byproduct in the Λ-theory of the nonuniform rotation in outer convection zones. The consequences of this situation for those dynamo theories of stellar activity are discussed which work with the meridional circulation as the dominant magnetic-advection effect in latitude to produce the solar-like form of the butterfly diagram.
