description: The telecommunications industry is characterized by rapid technological advancements, evolving customer expectations, and global market influences, necessitating continuous organizational adaptation to maintain competitiveness. However, resistance to change remains a significant challenge, often stemming from fear of the unknown, job security concerns, and disruptions to established workflows. This study explores the key drivers of change within the telecommunications sector, including technological evolution, customer demands, globalization, and employee productivity. Additionally, it examines the sources of resistance and highlights the necessity of effective change management strategies to mitigate opposition and ensure successful organizational transitions. By understanding the root causes of resistance and implementing structured change initiatives, telecommunications companies can foster adaptability, enhance employee acceptance, and sustain growth in an increasingly dynamic market. This research contributes to the ongoing discourse on change management within the telecommunications sector and offers practical insights for industry professionals to navigate transformation effectively.

description: The next generation of proton decay and neutrino experiments, the post-SuperKamiokande detectors as those that will take place in megaton size water tanks, will require very large surfaces of photodetection and a large volume of data. Even with large hemispherical photomultiplier tubes, the expected number of channels should reach hundreds of thousands. A funded R&D program to implement a solution is presented here. The very large surface of photodetection is segmented in macro pixels made of 16 hemispherical (12 inches) photomultiplier tubes connected to an autonomous front-end which works on a triggerless data acquisition mode. The expected data transmission rate is 5 Mb/s per cable, which can be achieved with existing techniques. This architecture allows to reduce considerably the cost and facilitate the industrialization. This document presents the simulations and measurements which define the requirements for the photomultipliers and the electronics. A proto-type of front-end electronics was successfully tested with 16 photomultiplier tubes supplied by a single high voltage, validating the built-in gain adjustment and the calibration principle. The first tests and calculations on the photomultiplier glass led to the study of a new package optimized for a 10 bar pressure in order to sustain the high underwater pressure.

description: The kinematic end-point technique for measuring the masses of supersymmetric particles in R-Parity conserving models at hadron colliders is re-examined with a focus on exploiting additional constraints arising from correlations in invariant mass observables. The use of such correlations is shown to potentially resolve the ambiguity in the interpretation of quark+lepton end-points and enable discrimination between sequential two-body and three-body lepton-producing decays. The use of these techniques is shown to improve the SUSY particle mass measurement precision for the SPS1a benchmark model by at least 20-30% compared to the conventional end-point technique.

description: We study human behavior from a Complex Systems and Computational Social Science approach within the PICAE project (Intelligent Publication of Audiovisual and Editorial Contents), where we are studying the Editorial and consumption behavior from the Complex Systems Science perspective. The aim is to characterize behavioral patterns from registered users. The data cover 6 months (May - November 2022) of Editorial consumption (GEC, Gran Enciclopèdia Catalana), hence we are dealing with the order of ~100.000 data records, which are carefully analyzed, processed and cleaned. In the statistical study of the data, we observed that the activity is much more frequently on weekdays than at weekends. An audience peak appears at early morning. At the weekend, a second audience peak appears in the afternoon. We have used a mixed data clustering algorithm to group the records (consumption units) into 3 distinct groups, which can be characterized by the time of consumption. We also found, through a machine learning algorithm, that the clusters can be predicted with high accuracy, and that the time of consumption is the most important variable/dimension to form each one of the clusters. We also analyzed carefully the logged users in the dataset, applying a continous data clustering algorithm. We found two groups of users, one made up of sporadic users (with few associated records), and who tend to consume more at weekends and in the afternoon. The other group is much smaller and consists of a few very loyal users (with many associated records) who tend to consume more in the morning and on weekdays. We have finally studied the interevent time events, which is the time (in seconds) between consecutive visits/records from a given user. The probability density function of all interevent times shows different time scales (exponential decay for small interevent times and power-law for larger times).

description: Intracellular transmission of information via chemical and transcriptional networks is thwarted by a physical limitation: the finite copy number of the constituent chemical species introduces unavoidable intrinsic noise. Here we provide a method for solving for the complete probabilistic description of intrinsically noisy oscillatory driving. We derive and numerically verify a number of simple scaling laws. Unlike in the case of measuring a static quantity, response to an oscillatory driving can exhibit a resonant frequency which maximizes information transmission. Further, we show that the optimal regulatory design is dependent on the biophysical constraints (i.e., the allowed copy number and response time). The resulting phase diagram illustrates under what conditions threshold regulation outperforms linear regulation.

description: Rejse ind i et mørkt hjerte ist wahrscheinlich eine der am häufigsten untersuchten Erzählungen von Peter Høeg. Neben postkolonialen Lesarten überwiegen dabei bisher intertextuelle Analysen. Dieser Aufsatz wählt einen neuen Ansatz und liest Høegs Text als poetologische Reflexion. Der Fokus liegt dabei auf einer Leitmetapher der Erzählung, die den metafiktionalen Diskurs prägt: auf dem Theater. Es soll gezeigt werden, dass der Text das Theater parasitisch dazu benutzt, eine Poetologie zu entwerfen, die Høegs Schreiben bis heute prägt. Das Aufgreifen des dekonstruktivistischen Begriffs des »Parasiten« soll dabei helfen, den Grundgedanken jener Poetologie genauer zu beschreiben: die Versöhnung postmoderner Beliebigkeit und moderner, moralisierender Ideologiekritik.
description: Rejse ind i et mørkt hjerte is probably one of Peter Høeg’s most extensively analysed stories. In addition to postcolonial readings, intertextual analyses have so far predominated. This essay chooses a novel approach by reading Høeg’s text as a poetological reflection. It focuses on a key metaphor of the story that shapes the metafictional discourse: the theatre. The aim is to show that the text »parasitically« uses the theatre to create a poetology that has impacted Høeg’s writing to this day. Introducing the deconstructivist concept of the »parasite« helps to describe the basic idea of that poetology in more detail: the reconciliation between postmodern arbitrariness and modern, moralizing ideology critique.

Pedestrian precincts in the city's central retail area
Creators: name: Harwood-Barnes, Geoffrey Arthur
Publisher: name: University of British Columbia
Year: 2011

description: This study has been concerned with an examination of the validity of the hypothesis, that the shopping precinct is an efficient solution to the conflict between the pedestrian and the vehicle, in established central retail shopping areas of the city. Efficient pedestrian circulation within the city's central retail area appears as a fundamental principle in the design of new city centres in Europe, and as an essential component of city centre redevelopment designs in North America. The problem of pedestrian access to central areas in North American cities is complicated by the extensive use of the private automobile. The demands for space produced by roads and car parks has led to a serious deterioration in the physical form of the city, most particularly at the city centre. The city's central area contains the largest groupings of retail stores and attracts shoppers from the whole metropolitan area. This retailing function is of vital importance, to the values of the downtown property, and to the city for the revenue it produces for city services and further city development. Excessive vehicular traffic creates congestion in the city central areas and inhibits the use of the area for the

On the representation theory of persistence modules
Creators: name: Lerch, Jan-Paul
Publisher: name: Universität Bielefeld
Year: 2023
Subjects: subject: 510

description: In this thesis we study representation theoretic aspects of persistence modules.
The first subject is an investigation of the spectrum of the category of vector space representations of a totally ordered set $T$:
We show the existence of and determine the spectrum of this category in the sense of Krause and Herzog, and then show that it is homeomorphic to the space of ideals of $T$ equipped with the order topology.
Using this homeomorphism we then study its further properties.

The second subject concerns the theory of middle exact representations:
We generalise and discuss the notions of middle exactness and block representations from two- to three-parameter persistence modules and generalise the decomposition theorem of Botnan and Crawley-Boevey to this case.

Both of this is complemented by a discussion of the representation theoretic foundations of persistence modules in terms of functor categories, reviewing their calculus, decomposition theory and homological properties.

Our research focuses on whether local stakeholders from civil society have sufficient capacities to contribute effectively and efficiently to EU Cohesion Policy implementation. We performed our research on 57 integrated urban development plans in Czechia and Portugal and conducted 33 interviews with local entities. The results indicate a different level of capacity not only between the public and civil society organizations but also within civil society.

description: Do governments represent the material needs and preferences of their voters? This is one of the central questions of political science with great consequences for how we should evaluate the state of democracy. A thorough test of the link between voters’ economic vulnerabilities and public policies is presented in the article. Using data covering 17 European democracies, it is shown empirically that economically vulnerable voters support generous unemployment protection; that parties adopt policy positions that correspond with these voter signals; that entire party systems can meaningfully be described by the economic vulnerabilities of parties’ voters; and that parties, when entering office, pursue policies aligned with their voters’ needs and preferences.

description: Recent American studies that investigate the influence of money on the outcome of direct democratic votes find campaign spending effective for both supporters and challengers. Taking advantage of Switzerland’s far-reaching experience with direct legislation, this article tests the role of money in a ‘harder’ context, where government plays an active role in direct democratic processes. It assesses the impact of campaign spending on 323 federal votes, and on a subset of 60 votes, offering finer-grained cantonal-level data. On the one hand, the results highlight the crucial role of the partisan coalition supporting the government for the outcome of votes; on the other hand, campaign spending is effective for both government and challenger camps, yet more so for the latter. Furthermore, the effects of government camp spending vary depending on the expected vote outcome and the difference in spending between both camps.

description: Partisan dealignment is recurrently presented in the literature as one of the main drivers of the ‘personalisation of politics’. Yet, on the one hand, the claim that leader effects on voting behaviour are increasing across time is short on comparative evidence. On the other hand, there is limited empirical evidence that such an increase is due to dealignment. This article explores the longitudinal relationship between partisan dealignment, leader effects and party choice, through a novel dataset pooling 109 national election surveys collected in 14 Western European parliamentary democracies across the last six decades. The results show that leader effects increased over time as a function of the decline of party identification. Additional panel evidence from selected countries shows that partisan dealignment is responsible for increasing leader effects on party choice at the individual level. The longitudinal dimension of this study contributes to the most contested aspect of the personalisation of politics debate.

description: Are unpopular ministers more likely to be forced out of office than their colleagues in Cabinet? This study examines the relationship between ministers’ unpopularity and their duration in office. By examining opinion polls on the popularity of ministers in Denmark in the period 1978 to 2019, the analysis shows that when Danish Prime Ministers choose to dismiss ministers, they dismiss ministers who are relatively less popular than their colleagues in the Cabinet. Statistical analyses show that less popular ministers have a higher probability of being dismissed. This is particularly true for ministers outside the inner circles of Cabinet. These results suggest that opinion polls on ministers’ individual popularity have been neglected in political science so far and should be considered in future studies of cabinet governments.

description: Technological developments have created a constant incoming stream of complex new data structures that need analysis. Modern statistics therefore means mathematically sophisticated new statistical theory that generates or supports innovative data-analytic methodologies for complex data structures. Inherent in many of these methodologies are challenging numerical optimization methods. The proposed workshop intends to bring together experts from mathematical statistics as well as statisticians involved in serious modern applications and computing. The primary goal of this meeting was to advance the mathematical and methodological underpinnings of modern statistics for complex data. Particular focus was given to the advancement of theory and methods under non-stationarity and complex dependence structures including (multivariate) ﬁnancial time series, scientiﬁc data analysis in neurosciences and bio-physics, estimation under shape constraints, and highdimensional discrimination/classiﬁcation.

description: By means of numerical simulations, we investigate magnetized stellar winds of pre-main-sequence stars. In particular we analyze under which circumstances these stars will present elongated magnetic features (e.g., helmet streamers, slingshot prominences, etc). We focus on weak-lined T Tauri stars, as the presence of the tenuous accretion disk is not expected to have strong influence on the structure of the stellar wind. We show that the plasma-beta parameter (the ratio of thermal to magnetic energy densities) is a decisive factor in defining the magnetic configuration of the stellar wind. Using initial parameters within the observed range for these stars, we show that the coronal magnetic field configuration can vary between a dipole-like configuration and a configuration with strong collimated polar lines and closed streamers at the equator (multi-component configuration for the magnetic field). We show that elongated magnetic features will only be present if the plasma-beta parameter at the coronal base is beta<<1. Using our self-consistent 3D MHD model, we estimate for these stellar winds the time-scale of planet migration due to drag forces exerted by the stellar wind on a hot-Jupiter. In contrast to the findings of Lovelace et al. (2008), who estimated such time-scales using the Weber & Davis model, our model suggests that the stellar wind of these multi-component coronae are not expected to have significant influence on hot-Jupiters migration. Further simulations are necessary to investigate this result under more intense surface magnetic field strengths (~2-3 kG) and higher coronal base densities, as well as in a tilted stellar magnetosphere.

description: The degradation mechanisms of multilayer graphene spin valves are investigated. The spin injection signals in graphene spin valves have been reported to be linearly dependent on the drain bias voltage, which indicates that the spin polarization of injected spins in graphene is robust against the bias voltage. We present that the disappearance of this robustness is due to two different degradation mechanisms of the spin valves. Our findings indicate that the disappearance of the robustness is due to degradation rather than an intrinsic characteristic of graphene. Thus, the robustness can be greatly enhanced if degradation can be prevented.

A New Non-Intercepting Beam Size Diagnostics Using Diffraction Radiation from a Slit
Creators: name: M. Castellano
Publisher: name: INFN Open Access Repository
Year: 1996

description: A new non intercepting beam size diagnostics for high charge electron beams is presented. This diagnostics is based on the analysis of the angular distribution of the 'diffracted' transition radiation emitted by the beam when crossing a slit cut in metallic foil. It allows a resolution better then the radiation transverse formation zone. Numerical results based on the parameters of the TTF FEL beam are given as examples.

description: The development, analysis and implementation of eﬃcient and robust numerical techniques for optimization problems associated with partial diﬀerential equations (PDEs) is of utmost importance for the optimal control of processes and the optimal design of structures and systems in modern technology. The successful realization of such techniques invokes a wide variety of challenging mathematical tasks and thus requires the application of adequate methodologies from various mathematical disciplines. During recent years, signiﬁcant progress has been made in PDE constrained optimization both concerning optimization in function space according to the paradigm ’Optimize ﬁrst, then discretize’ and with regard to the fast and reliable solution of the large-scale problems that typically arise from discretizations of the optimality conditions. The contributions at this Oberwolfach workshop impressively reﬂected the progress made in the ﬁeld. In particular, new insights have been gained in the analysis of optimal control problems for PDEs that have led to vastly improved numerical solution methods. Likewise, breakthroughs have been made in the optimal design of structures and systems, for instance, by the socalled ’all-at-once’ approach featuring simultaneous optimization and solution of the underlying PDEs. Finally, new methodologies have been developed for the design of innovative materials and the identiﬁcation of parameters in multi-scale physical and physiological processes.

description: We have conducted a Galactic plane survey of methanol masers at 6668 MHz using a 7-beam receiver on the Parkes telescope. Here we present results from the first part, which provides sensitive unbiased coverage of a large region around the Galactic Centre. Details are given for 183 methanol maser sites in the longitude range 345$^{\circ}$ through the Galactic Centre to 6$^{\circ}$. Within 6$^{\circ}$ of the Centre, we found 88 maser sites, of which more than half (48) are new discoveries. The masers are confined to a narrow Galactic latitude range, indicative of many sources at the Galactic Centre distance and beyond, and confined to a thin disk population; there is no high latitude population that might be ascribed to the Galactic Bulge. Within 2$^{\circ}$ of the Galactic Centre the maser velocities all lie between -60 and +77 \kms, a range much smaller than the 540 \kms range observed in CO. Elsewhere, the maser with highest positive velocity (+107 \kms) occurs, surprisingly, near longitude 355$^{\circ}$ and is probably attributable to the Galactic bar. The maser with the most negative velocity (-127 \kms) is near longitude 346$^{\circ}$, within the longitude-velocity locus of the near side of the `3-kpc arm'. It has the most extreme velocity of a clear population of masers associated with the near and far sides of the 3-kpc arm. Closer to the Galactic Centre the maser space density is generally low, except within 0.25 kpc of the Centre itself, the `Galactic Centre Zone', where it is 50 times higher, which is hinted at by the longitude distribution, and confirmed by the unusual velocities.

description: We report on the status of the first Italian Infrared Synchrotron Radiation Beamline SINBAD (Synchrotron INfrared Beamline At  DAFNE), that has been designed to work at wavelengths greater than 10 mm. SINBAD is being installed on DAFNE, the new collider of the Laboratori Nazionali di Frascati designed to work at 0.51 GeV with a beam current of 2 to 5 A. The infrared radiation extracted from a bending magnet under an angle of 50x50 mrad will be two orders of magnitude more brilliant than that of a black body at 2000 K at a wavelength of 100 mm. The beamline layout, which consists of two plane mirrors, two toroidal mirrors, and one aspherical mirror, has been designed by ray tracing simulation. In this layout one ellipsoid focuses the radiation on a wedged CVD diamond-film window, the beam is than re-focused again on the entrance of an interferometer. With a calculated transmittance of the optics between 60% and 80% at 50 mm, this beamline will allow experiments which require a very high brilliance in the far infrared.

description: One of the most striking results from the Relativistic Heavy Ion Collider is the strong elliptic flow. This review summarizes what is observed and how these results are combined with reasonable theoretical assumptions to estimate the shear viscosity of QCD near the phase transition. A data comparison with viscous hydrodynamics and kinetic theory calculations indicates that the shear viscosity to entropy ratio is surprisingly small, $η/s < 0.4$. The preferred range is $η/s \simeq (1\leftrightarrow 3) \times 1/4π$.
