title: Historische Zäsuren der Nachkriegsära im Spiegel politischer Reden
Creators: name: Kartusch, Jessica
Year: 2023

description: Die vorliegende Masterarbeit untersucht die politische Sprache in sechs Reden deutscher und österreichischer Spitzenpolitiker – Karl Renner, Leopold Figl, Konrad Adenauer, Richard von Weizsäcker, Franz Vranitzky und Willy Brandt – im Kontext zweier bedeutender historischer Zäsuren nach 1945, nämlich der unmittelbaren Nachkriegszeit einerseits und der Zeit des Endes des Kalten Krieges bzw. der Wiedervereinigung Deutschlands andererseits. Den theoretischen Rahmen bilden dabei die soziolinguistischen Paradigmen der Polito- und Diskurslinguistik sowie Erkenntnisse der Forschung zur österreichischen und deutschen Zeitgeschichte. Die erste Forschungsfrage zielte auf Parallelen und Unterschiede in den untersuchten Reden in Bezug auf sprachlich-funktionale Mittel, ideologische Positionierungen und historische Bezüge ab. In Beantwortung der zweiten Forschungsfrage wurden markante Unterschiede zwischen den Reden der österreichischen und deutschen Politiker hinsichtlich der Aufarbeitung der NS-Vergangenheit/Schuld herausgearbeitet. Besonderer Fokus wurde dabei auf die Problematik der Österreich lang prägenden „Opferthese“ gelegt. Das Forschungsdesign der Masterarbeit impliziert sowohl eine hermeneutische Auswertung von Fachliteratur als auch eine inhaltlich strukturierende qualitative Inhaltsanalyse (nach Kuckartz / Rädiker 2022) der sechs Reden mittels Applikation der Software MAXQDA. In den Ergebnissen zeigen sich sowohl Parallelen als auch Unterschiede zwischen den ausgewählten Reden. Ersteres gilt vor allem hinsichtlich der ideologischen Positionierung der Redner, der negativen Haltung gegenüber dem nationalsozialistischen Regime und in Bezug auf das hohe stilistische Niveau der Reden. Unterschiede zeigen sich unter anderem bezüglich der Ansichten über die Aufarbeitung der NS-Schuld, wobei die historische Einbettung der jeweiligen Rede eine Rolle spielt. Vor diesem Hintergrund konnten neue Erkenntnisse zur politischen Sprache in Reden österreichischer und deutscher Politiker gewonnen werden, die anschlussfähig für weitere Untersuchungen sind.
title: Pachakutik
Creators: name: Seidl, Gregor
Year: 2023

description: Die Arbeit befasst sich mit dem indigenen andinen Konzept Pachakutik, das eine radikale Tranformation beziechnet in der jedes Element in sein Gegenteil verkehrt wird. Im Rahmen eines Polylogs theoretischer Strömungen aus dem Globalen Norden und Globalen Süden wird eine theoretische Herantastung an das Konzept Pachakutik geleistet und mit dem in der Literatur vorhandenen Bedeutungshorizont von Pachakutik kontrastiert. Im Anschluss an diese theoretische Arbeit werden empirische Dimensionen des Konzepts Pachakutik diskutiert, wie sie in den sozialen Praktiken andiner indigener Akteure auftauchen. Dabei wird auf Material zurückgegriffen, dasss im Rahmen zweier Forschungsaufenthalte in den Anden in Form von episodischen Interviews und Gruppendiskussionen gewonnen wurde.
description: This thesis deals with the indigenous concept of Pachakutik, which refers to a radical transformation where every element is turned into its opposite. A theoretical introduction is achieved by a polylog between theoretical currents form the Global North and the Global South, which serves as an entry point for the theoretical discussion of the concept of Pachakutik as found in the literature. Following this theoretical work is the analysis of some empirical notions and dimensions of the concept, which draws on the social practices of indigenous actors in the Andes. The basis for this analysis is formed by material that was collected during two research stays in the Andes by using episodic interviews and group discussions.
Formulation of an Electrostatic Field with a Charge Density in the Presence of a Minimal Length Based on the Kempf Algebra

description: In a series of papers, Kempf and co-workers (J. Phys. A: Math. Gen. {\bf 30}, 2093, (1997); Phys. Rev. D {\bf52}, 1108, (1995); Phys. Rev. D {\bf55}, 7909, (1997)) introduced a D-dimensional $(β,β')$-two-parameter deformed Heisenberg algebra which leads to a nonzero minimal observable length. In this work, the Lagrangian formulation of an electrostatic field in three spatial dimensions described by Kempf algebra is studied in the case where $β'=2β$ up to first order over deformation parameter $β$. It is shown that there is a similarity between electrostatics in the presence of a minimal length (modified electrostatics) and higher derivative Podolsky's electrostatics. The important property of this modified electrostatics is that the classical self-energy of a point charge becomes a finite value. Two different upper bounds on the isotropic minimal length of this modified electrostatics are estimated. The first upper bound will be found by treating the modified electrostatics as a classical electromagnetic system, while the second one will be estimated by considering the modified electrostatics as a quantum field theoretic model. It should be noted that the quantum upper bound on the isotropic minimal length in this paper is near to the electroweak length scale $(\ell_{electroweak}\sim 10^{-18}\, m)$.

description: We consider supervised learning problems within the positive-definite kernel framework, such as kernel ridge regression, kernel logistic regression or the support vector machine. With kernels leading to infinite-dimensional feature spaces, a common practical limiting difficulty is the necessity of computing the kernel matrix, which most frequently leads to algorithms with running time at least quadratic in the number of observations n, i.e., O(n^2). Low-rank approximations of the kernel matrix are often considered as they allow the reduction of running time complexities to O(p^2 n), where p is the rank of the approximation. The practicality of such methods thus depends on the required rank p. In this paper, we show that in the context of kernel ridge regression, for approximations based on a random subset of columns of the original kernel matrix, the rank p may be chosen to be linear in the degrees of freedom associated with the problem, a quantity which is classically used in the statistical analysis of such methods, and is often seen as the implicit number of parameters of non-parametric estimators. This result enables simple algorithms that have sub-quadratic running time complexity, but provably exhibit the same predictive performance than existing algorithms, for any given problem instance, and not only for worst-case situations.

description: We address the question of the dualizability of nilpotent Mal'cev algebras, showing that nilpotent finite Mal'cev algebras with a non-abelian supernilpotent congruence are inherently non-dualizable. In particular, finite nilpotent non-abelian Mal'cev algebras of finite type are non-dualizable if they are direct products of algebras of prime power order. We show that these results cannot be generalized to nilpotent algebras by giving an example of a group expansion of infinite type that is nilpotent and non-abelian, but dualizable. To our knowledge this is the first construction of a non-abelian nilpotent dualizable algebra. It has the curious property that all its non-abelian finitary reducts with group operation are non-dualizable. We were able to prove dualizability by utilizing a new clone theoretic approach developed by Davey, Pitkethly, and Willard. Our results suggest that supernilpotence plays an important role in characterizing dualizability among Mal'cev algebras.

description: We demonstrate how the Syer & Tremaine made-to-measure method of stellar dynamical modelling can be adapted to model a rotating galactic bar. We validate our made-to-measure changes using observations constructed from the existing Shen et al. (2010) N-body model of the Milky Way bar, together with kinematic observations of the Milky Way bulge and bar taken by the Bulge Radial Velocity Assay (BRAVA). Our results for a combined determination of the bar angle and bar pattern speed (~30 degrees and ~40 km/s/kpc) are consistent with those determined by the N-body model. Whilst the made-to-measure techniques we have developed are applied using a particular N-body model and observational data set, they are in fact general and could be applied to other Milky Way modelling scenarios utilising different N-body models and data sets. Additionally, we use the exercise as a vehicle for illustrating how N-body and made-to-measure methods might be combined into a more effective method.

description: The use of power lines as a communication channel for transferring data between communication devices for power systems in smart grid communication systems is growing rapidly. This paper describes three different types of methods for radiating and conducting Intentional Electromagnetic Interference, IEMI, signals: Amplitude Modulated, Damped Sinusoidal and Sweep Frequency Jamming Signals. The severity of all three types of IEMI signals on a power line communication channel using a single phase of a three-phase, low-voltage power distribution board is compared. The method for measuring interference is then explained and the influence of radiated and conducted interferences on data transmission is assessed. After discussing the IEEE 1901 power line communication channel's vulnerability to IEMI, this article explains the need for a systematic risk-based approach, in coalition with the rules-based perspective, to mitigate its impact.© 2021 IEEE.

description: Multiple hard and semi-hard parton scatterings in high-energy $p+A$ collisions involve multi-parton correlation in both momentum and flavor inside the projectile proton which will lead to modification of the final hadron spectra relative to that in $p+p$ collisions. Such modification of final hadron transverse momentum spectra in $p+A$ collisions is studied within HIJING 2.1 Monte Carlo model which includes nuclear shadowing of the initial parton distributions and transverse momentum broadening. Multi-parton flavor and momentum correlation inside the projectile are incorporated through flavor and momentum conservation which are shown to modify the flavor content and momentum spectra of final partons and most importantly lead to suppression of large $p_{T}$ hadron spectra in $p+A$ collisions at both RHIC and LHC energies.

description: We present a wide (8.5x6.7 degree, 1050x825 kpc), deep (sigma(N_HI)=10^(16.8-17.5) cm^-2) neutral hydrogen (HI) map of the M101 galaxy group. We identify two new HI sources in the group environment, one an extremely low surface brightness (and hitherto unknown) dwarf galaxy, and the other a starless HI cloud, possibly primordial in origin. Our data show that M101's extended HI envelope (Huchtmeier & Witzel 1979) takes the form of a ~100 kpc long tidal loop or plume of HI extending to the southwest of the galaxy. The plume has an HI mass ~ 10^8 Msun and a peak column density of N_HI=5x10^17 cm^-2, and while it rotates with the main body of M101, it shows kinematic peculiarities suggestive of a warp or flaring out of the rotation plane of the galaxy. We also find two new HI clouds near the plume with masses ~ 10^7 Msun, similar to HI clouds seen in the M81/M82 group, and likely also tidal in nature. Comparing to deep optical imaging of the M101 group, neither the plume nor the clouds have any extended optical counterparts down to a limiting surface brightness of mu_B = 29.5. We also trace HI at intermediate velocities between M101 and NGC 5474, strengthening the case for a recent interaction between the two galaxies. The kinematically complex HI structure in the M101 group, coupled with the optical morphology of M101 and its companions, suggests that the group is in a dynamically active state that is likely common for galaxies in group environments.

description: L’articolo è frutto di una ricerca etnografica condotta nell’area metropolitana romana di Bastogi. Si tratta di un comprensorio di proprietà comunale impiegato per arginare l’emergenza alloggiativa temporanea. Tale temporaneità, per una parte degli interlocutori incontrati, dura da circa trent’anni. Si cercherà preliminarmente di inquadrare questo territorio nella cornice storica della cronica crisi abitativa romana, attraverso l’azione (e l’interazione) di personaggi pubblici, militanti, occupanti, imprenditori, rappresentanti del potere e subalterni che dagli anni ‘70 ad oggi – in una progressiva deriva neoliberista della questione urbana – hanno contribuito a ‘fondare’ e poi a ‘rifondare’ questo luogo. Nella parte conclusiva, le restituzioni etnografiche offriranno lo spunto per riflettere sul significato di spazio (pubblico, come privato) e delle sue forme di negoziazione, legate ai processi di soggettivazione e di adattamento alla marginalità.

description: We introduce a model independent method for the determination of the hadronic contribution to the QED running coupling, $Δα_{\text{HAD}}(M_{Z}^{2})$, requiring no $e^+e^-$ annihilation data as input. This is achieved by calculating the heavy-quark contributions entirely in perturbative QCD, whilst the light-quark resonance piece is determined using available lattice QCD results. Future reduction in the current uncertainties in the latter shall turn this method into a valuable alternative to the standard approach. Subsequently, we find that the precision of current determinations of $Δα_{\text{HAD}}(M_{Z}^{2})$ can be improved by some 20% by computing the heavy-quark pieces in PQCD, whilst using $e^+e^-$ data only for the low-energy light-quark sector. We obtain in this case $Δα_{\text{HAD}}(M_{Z}^{2})=275.7(0.8) \times 10^{-4}$, which currently is the most precise value of $Δα_{\text{HAD}}(M_{Z}^{2})$.

title: Der Einfluss von neuen Medien auf die Lesemotivation von SchülerInnen

Year: 2023

description: Diese Arbeit im Rahmen des Masterstudiums Lehramt Deutsch am Institut für Germanistik der Universität Wien untersucht den Einfluss von neuen Medien auf die Lesemotivation von SchülerInnen aus drei unterschiedlichen Schultypen im Weinviertel in Niederösterreich. Methodisch stützt sich die Untersuchung auf quantitative Daten, welche mittels Fragebogen erhoben wurden. Der umfassende Fragebogen, der sowohl die Nutzung neuer Medien als auch die Einstellung zur Lektüre sowie soziale Einflussfaktoren erfasst, wurde von SchülerInnen im Alter von 13 bis 16 Jahren online ausgefüllt. Die Untersuchung zeigt sehr konträre Ergebnisse im Bezug zu den PISA-Studien. Dies rührt daher, dass die SchülerInnen den Fragebogen nach ihrer eigenen Einschätzung ausfüllen. Hier ist deutlich erkennbar, dass sich Mädchen, im Vergleich zu ihrem geschlechtlichen Pendant, selbst schlechter einschätzen. Die Ergebnisse dieser Arbeit zeigen, dass es keinen Zusammenhang zwischen Lesemotivation und Lesekompetenz gibt. Zwischen dem Mediennutzungsverhalten und der Lesehäufigkeit besteht ein bedingter Zusammenhang. Der Einfluss von neuen Medien kann folglich sowohl positiv als auch negativ ausfallen.
description: This thesis, as part of the master’s degree in German Studies at the University of Vienna, examines the influence of new media on the reading motivation of students from three different types of schools in the Weinviertel region of Lower Austria. In terms of methodology, the study is based on quantitative data collected through a questionnaire. The comprehensive questionnaire, which captures both the use of new media, attitudes towards reading, and social influencing factors, was completed online by students aged 13 to 16. The study reveals highly contrasting results compared to the PISA studies. This is because students complete the questionnaire based on their self-assessment. In comparison to their male counterparts, female students rate themselves lower. The results of this study show that there is no correlation between reading motivation and reading competence. There is a conditional relationship between media usage behavior and reading frequency. Therefore, the influence of new media can be both positive and negative.

description: We study the interface between a fractional topological insulator and an ordinary insulator, both described using holography. By turning on a chemical potential we induce a finite density of matter localized at the interface. These are gapless surface excitations which are expected to have a fermionic character. We study the thermodynamics of the system, finding a symmetry preserving compressible state at low temperatures, whose excitations exhibit hyperscaling violation. These results are consistent with the expectation of gapless fermionic excitations forming a Fermi surface at finite density.

Contrast of LiFeAs with isostructural, isoelectronic, and non-superconducting MgFeGe

description: Stoichiometric LiFeAs at ambient pressure is an 18 K superconductor while isoelectronic MgFeGe is not, despite their extremely similar electronic structures. To investigate possible sources of this distinctively different superconducting behavior, we quantify the differences using first principles density functional theory, establishing first that the Fe total 3d occupations are identical in the two compounds. Individual 3d orbital occupations also differ very little ($\sim 0.01$). The differences in Fermi surfaces (FSs) do not seem significant; however a redistribution of bands just above the Fermi level does represent a possibly significant distinction. Because the bands and FSs of LiFeAs are less in agreement with experiment than for other iron-pnictides, we study the effects of additional exchange-correlations effects beyond GGA (the generalized gradient approximation) by applying the modified Becke-Johnson potential (mBJ) exchange potential, which gives much improved bandgaps in insulators compared to GGA and might be useful for semimetals such as the Fe-based superconductors. Overall, we conclude that the mBJ corrections do not improve the description of LiFeAs as compared to experiment.

A Minimal Flavor Violating 2HDM at the LHC

description: We explore the phenomenology of a two Higgs doublet model where both Higgs doublets couple to up-type and down-type fermions with couplings determined by the minimal flavor violation ansatz. This 2HDM "Type MFV" generalizes 2HDM Types I-IV, where the decay rates of h --> bb and h --> tau+tau- are governed by MFV couplings independent of the Higgs couplings to gauge bosons or the top quark. To determine the implications of the present Higgs data on the model, we have performed global fits to all relevant data. Several surprisingly large effects on the light Higgs phenomenology can arise: (1) The modified couplings of the Higgs to fermions can enhance the h --> gamma gamma rate significantly in both VBF production (up to a factor of 3 or more) and the inclusive rate (up to a factor of 1.5 or more). (2) In the 2HDM Type MFV, the constraints on a light charged Higgs are milder than in 2HDM Types I-IV. Thus, there can be substantial charged Higgs loop contribution to the di-photon rate, allowing further enhancements of the di-photon rates. (3) The h --> tau+tau- rate can be (highly) suppressed, independently of the other decay channels. Furthermore, we studied the correlation between the light Higgs and the heavy Higgs phenomenology. We showed that even small deviations from the decoupling limit would imply good prospects for the detection of the heavy Higgs boson. In some regions of parameter space, a substantial range of M_H is already either ruled out or on the edge of detection. Finally we investigated the possibility that the heavy Higgs is close in mass to the light Higgs, providing additional h/H --> bb rate, as well as confounding the extraction of properties of the Higgs bosons.

description: This policy brief provides an overview of the educational sector in Lebanon immediately prior to the escalation of Israel’s aggression in the autumn of 2024. Establishing a baseline for the conditions in the sector is essential for assessing the expected significant impacts on education in Lebanon. By evaluating the educational landscape just before the escalation of Israel’s aggression, this brief will help in formulating strategic and targeted interventions in educational policy and practice for both the immediate crisis and its protracted impacts while also considering the pre-existing challenges in Lebanon’s education sector.The policy brief outlines necessary actions for educational recovery and strategies to prevent further school disruptions in light of recent events. The challenges outlined are primarily based on insights from two online surveys conducted by the Centre for Lebanese Studies between June and August 2024. The first survey targeted 406 grade 12 students, with 48% attending private schools and 52% attending public schools, spanning all eight Lebanese governorates. The second survey targeted 2,075 parents from across all eight Lebanese governorates, encompassing a diverse range of educational levels: 9% with children in preschool, 47% in primary school, 28% in middle school, and 16% in high school. Together the findings from both surveys offer a comprehensive view of the issues from both student and parental perspectives. They reveal the extensive impact on education of prolonged disruptions and financial hardships, compounded by ongoing Israeli aggression, all of which are threatening the future of education in Lebanon and are expected to increase significantly.

description: We present large-scale simulations of radial Eden clusters in three-dimensions and show that the growth exponent is in agreement with the value $β=0.242$ accepted for the Kardar-Parisi-Zhang (KPZ) universality class. Our results refute a recent assertion proposing that radial Eden growth in $d=3$ belongs to a universality class distinct from KPZ. We associate the previously reported discrepancy to a slow convergence to the asymptotic limit. We also present the skewness and kurtosis in the roughening regime for flat geometry in 2+1 dimensions.

Territorializzare la transizione

description: Il “Next Generation EU” presenta la transizione verde come un campo plurale di raccordo dei singoli pilastri dell’azione comunitaria: una visione non più limitata alla modernizzazione ecologica che lo “European Green Deal” inquadra in obiettivi di mitigazione delle emissioni climalteranti e di adattamento dei territori. In Italia tale progetto non ha incontrato una pari capacità di innovare strumenti, modalità e azioni di contrasto al clima e il PNRR appare piuttosto un insieme di tattiche deterritorializzate senza un’organica strategia per affrontare i rischi e le vulnerabilità a cui risultano, a volte drammaticamente, esposti i territori nei sempre più frequenti eventi climatici che colpiscono il Paese. A fronte di una fragilità causata da interventi consolidati con emergenze reiterate e da molti anni offerte quale unica risposta alle devastazioni, la territorializzazione offre un'alternativa adeguata alla complessità delle sfide ambientali che invece ci attendono.

Metacrangon clevai

description: Metacrangon clevai Komai, 2012 (Figs. 3, 4B) Metacrangon clevai Komai, 2012: 34, figs. 16–18, 43 (type locality: Solomon Islands, 1,001–1,012 m). Material examined. 1 female (cl 7.4 mm), SJADES, stn DW 32, S of Java, 07°42.58′S, 107°34.54′E to 07°42.56′S, 107°35.93′E, 977– 805 m, 29 March 2018, dredge, ZRC 2019.1872. Colouration in life. Body generally maroon; cornea reflective; antennular and antennal peduncles also brownish; maxilliped 3 antepenultimate article brownish, distal two articles paler; pereopod 1 generally pale brown, darker at subdistal part of palm; pereopods 2–5 generally semitransparent, with tinge of brown on ischium and merus of pereopod 4. Pleopods also semitransparent with tinge of brown on protopods. Distribution. Previously only known from the Solomon Islands and Vanuatu, at depths of 777–1,040 m. Newly recorded from south of Java, Indonesia, at depths of 805– 977 m. Remarks. The present specimen from the south of Java generally agrees with the description of Metacrangon clevai in the following diagnostic features (see Komai, 2012): (1) the carapace has two middorsal spines, the anterior one located in an epigastric position; (2) there are no submedian spines on the gastric region of the carapace; and (3) the pleomeres 2–4 possess an obsolescent middorsal carina. Only minor differences are observed between this Java specimen and the type material: (1) the anterior middorsal spine on the carapace is relatively longer and narrower in the present specimen than in the type specimens (Fig. 3A; Komai, 2012: figs. 16B, 18A); and (2) the posterior middorsal spine arises slightly anterior to the midlength in the newly collected specimen (Fig. 3A), whereas in the type specimens, it rises at the midlength or slightly posterior to it (Komai, 2012: figs. 16B, 18A).

description: Equilibrium canonical distribution in statistical mechanics assumes weak system-bath coupling (SBC). In real physical situations this assumption can be invalid and equilibrium quantum statistics of the system may be non-canonical. By exploiting both polaron transformation and perturbation theory in a spin-boson model, an analytical treatment is advocated to study non-canonical statistics of a two-level system at arbitrary temperature and for arbitrary SBC strength, yielding theoretical results in agreement with exact Monte-Carlo simulations. In particular, the eigen-representation of system's reduced density matrix is used to quantify non-canonical statistics as well as the quantumness of the open system. For example, it is found that irrespective of SBC strength, non-canonical statistics enhances as temperature decreases but vanishes at high temperature.

SJADES, stn CP 13, S of Java, 06°00.52′S, 104°49.41′E to 06°00.83′S, 104°49.43′E, 1,259–1,268 m, 26 March 2018, beam trawl, 1 ovigerous female (cl 12.9 mm), ZRC 2019.1873; stn CP 18, S of Java, 06°10.76′S, 105°05.59′E to 16°11.59′S, 105°05.74′E, 1,060–1,073 m, 26 March 2018, beam trawl, 1 male (cl 7.4 mm), 1 ovigerous female (cl 12.5 mm), ZRC 2019.1874. Colouration in life. Body generally whitish; carapace with tinge of purplish brown anterodorsally; pleon mottled with purplish brown markings at least on pleomeres 3–5, pleomere 6 semitransparent; cornea brownish, reflective; antennular and antennal peduncles purplish brown; pereopod 1 whitish, semitransparent; pereopods 4 and 5, pleopods and uropods generally purplish brown (Fig. 4 C–E). Distribution. Previously known from the Banda Sea (Indonesia), Papua New Guinea, Solomon Islands, and New Caledonia, at depths of 670–1,135 m. The present specimens came from the south of Java, Indonesia, at depths of 1,060 –1,268 m, extending the geographical range of the species to the eastern Indian Ocean. Remarks. As Komai (2012) argued, M. punctata can be assigned to the “ M. jacqueti ” species group, characterised by the greatly enlarged anterior middorsal spine on the carapace at least partially overhanging the rostrum, the possession of a ventral marginal tooth on each pleonal pleuron 1–3, and the marginally setose dactyli of the pereopods 4 and 5. The southern Java specimens agree well with the type material, particularly in the punctate branchial region of the carapace (Fig. 4 C–E), one of the characteristics of M. punctata.

Simultaneous local exact controllability of 1D bilinear Schrödinger equations

Subjects: subject: Optimization and Control (math.OC)

description: We consider N independent quantum particles, in an infinite square potential well coupled to an external laser field. These particles are modelled by a system of linear Schrödinger equations on a bounded interval. This is a bilinear control system in which the state is the N-tuple of wave functions. The control is the real amplitude of the laser field. For N=1, Beauchard and Laurent proved local exact controllability around the ground state in arbitrary time. We prove, under an extra generic assumption, that their result does not hold in small time if N is greater or equal than 2. Still, for N=2, we prove using Coron's return method that local controllability holds either in arbitrary time up to a global phase or exactly up to a global delay. We also prove that for N greater or equal than 3, local controllability does not hold in small time even up to a global phase. Finally, for N=3, we prove that local controllability holds up to a global phase and a global delay.

description: The ALICE experiment at the LHC is equipped with an electromagnetic calorimeter (EMCal) designed to enhance its capabilities for jet, photon and electron measurement. In addition, the EMCal enables triggering on jets and photons with a centrality dependent energy threshold. After its commissioning in 2010, the EMCal Level 1 (L1) trigger was officially approved for physics data taking in 2011. After describing the L1 hardware and trigger algorithms, the commissioning and the first year of running experience, both in proton and heavy ion beams, are reviewed. Additionally, the upgrades to the original L1 trigger design are detailed.
