description: We study numerically the impact of many-body interactions on the quantum boomerang effect. We consider various cases: weakly interacting bosons, the Tonks-Girardeau gas, and strongly interacting bosons (which may be mapped onto weakly interacting fermions). Numerical simulations are performed using the time-evolving block decimation algorithm, a quasi-exact method based on matrix product states. In the case of weakly interacting bosons, we find a partial destruction of the quantum boomerang effect, in agreement with the earlier mean-field study [Phys. Rev. A \textbf{102}, 013303 (2020)]. For the Tonks-Girardeau gas, we show the presence of the full quantum boomerang effect. For strongly interacting bosons, we observe a partial boomerang effect. We show that the destruction of the quantum boomerang effect is universal and does not depend on the details of the interaction between particles.

description: We use a direct QCD approach to carry out the next-to-next-to-leading logarithmic (NNLL) resummation for observables groomed with the modified mass-drop tagger (Soft Drop $β=0$). We focus on observables which are additive given an arbitrary number of soft-collinear emissions. For this class of observables, we arrange the structure of the NNLL terms into two distinct categories. The first defines a simplified inclusive tagger, whereby the NNLL collinear structure is directly related to ungroomed observables. The second defines a clustering correction which takes a particularly simple form when the Cambridge-Aachen (C/A) algorithm is used to cluster the jets. We provide, in addition to the QCD resummation of groomed jet mass, the first NNLL resummed predictions, matched to NLO, for a range of groomed jet angularities with mMDT grooming. Moreover, we also include for the first time in the same calculation, finite $z_{\mathrm{cut}}$ effects computed at NLL level alongside the small $z_{\mathrm{cut}}$ NNLL results which simultaneously improves upon both of the calculations used for groomed jet mass phenomenological studies to date. While for simplicity we focus on $e^{+}e^{-}$ collisions, the essential NNLL resummation we develop is process independent and hence with the appropriate NLO matching our results are also applicable for hadron collider phenomenology.

description: We initiate a novel formalism for computing correlation functions of trace operators in the planar N=4 SYM theory. The central object in our formalism is the spin vertex, which is the weak coupling analogy of the string vertex in string field theory. We construct the spin vertex explicitly for all sectors at the leading order using a set of bosonic and fermionic oscillators. We prove that the vertex has trivial monodromy, or put in other words, it is a Yangian invariant. Since the monodromy of the vertex is the product of the monodromies of the three states, the Yangian invariance of the vertex implies an infinite exact symmetry for the three-point function. We conjecture that this infinite symmetry can be lifted to any loop order.

On the Possibility of Large Axion Moduli Spaces

Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: We study the diameters of axion moduli spaces, focusing primarily on type IIB compactifications on Calabi-Yau three-folds. In this case, we derive a stringent bound on the diameter in the large volume region of parameter space for Calabi-Yaus with simplicial Kähler cone. This bound can be violated by Calabi-Yaus with non-simplicial Kähler cones, but additional contributions are introduced to the effective action which can restrict the field range accessible to the axions. We perform a statistical analysis of simulated moduli spaces, finding in all cases that these additional contributions restrict the diameter so that these moduli spaces are no more likely to yield successful inflation than those with simplicial Kähler cone or with far fewer axions. Further heuristic arguments for axions in other corners of the duality web suggest that the difficulty observed in hep-th/0303252 of finding an axion decay constant parametrically larger than $M_p$ applies not only to individual axions, but to the diagonals of axion moduli space as well. This observation is shown to follow from the weak gravity conjecture of hep-th/0601001, so it likely applies not only to axions in string theory, but also to axions in any consistent theory of quantum gravity.

description: The purpose of this file is to document measuring spectral information from large sound files. The initial project for which this code was conceived contained 106,769 hours of long-term recordings. The method proposed here used FFmpeg in the command line prompt of windows to trim large (2 GB) files into many 3-minute files, starting at the beginning of each hour (code can be customized to make the starting period whenever the user wants). Then, we use R and some pre-built packages (tuneR and seewave) to calculate first and third quartiles, median frequency, and bandwidth (Q3-Q1).

description: Superresolution is one of the key issues at the crossroads of contemporary quantum optics and metrology. Recently, it was shown that for an idealized case of two balanced sources, spatial mode demultiplexing (SPADE) achieves resolution better than direct imaging even in the presence of measurement crosstalk [Phys. Rev. Lett. 125, 100501 (2020)]. In this work, we consider arbitrarily unbalanced sources and provide a systematic analysis of the impact of crosstalk on the resolution obtained from SPADE. As we dissect, in this generalized scenario, SPADE's effectiveness depends non-trivially on the strength of crosstalk, relative brightness and the separation between the sources. In particular, for any source imbalance, SPADE performs worse than ideal direct imaging in the asymptotic limit of vanishing source separations. Nonetheless, for realistic values of crosstalk strength, SPADE is still the superior method for several orders of magnitude of source separations.

title: Eavesdropping in pet dogs (Canis lupus familiaris) in relation to experience in years with humans
Creators: name: Belfiore, Kadisha

description: Kooperation ist essenziell für das Überleben für Tiere, die in Gruppen leben. Die Reputationsbildung über andere Gruppenmitglieder ist eine Schlüsselkomponente, die die Zusammenarbeit erleichtern kann. Die Reputation eines Individuums kann durch direkte Erfahrung oder indirekte Erfahrung, auch „Eavesdropping“ genannt, gebildet werden. „Eavesdropping“ ist ein Prozess der Informationsgewinnung durch Beobachtung und Lauschen der Interaktionen Dritter. Hunde (Canis lupus familiaris) sind eine gute Modellart für die Untersuchung von „Eavesdropping", da sie mit dem Menschen in enger Kooperation stehen. Wir untersuchten, ob Haushunde diese Fähigkeit der indirekte Reputationsbildung besitzen, indem sie eine Mensch-Tier-Interaktionen beobachteten, bei denen eine großzügige Person einen Artgenossen fütterte und eine egoistische Person dies nicht tat. Wir testeten auch, ob ältere Hunde mit mehr Lebenserfahrung eher lauschen/beobachten als jüngere Hunde. Wir fanden keine signifikanten Ergebnisse für unsere Hypothese, dass Hunde sich indirekt Informationen beschaffen können. Die Hunde wählten die großzügige Person daher nicht öfters als die egoistische und es gab keine Unterschiede zwischen den Altersgruppen. Unsere Studie zeigt, dass „Eavesdropping“ eine kognitiv anspruchsvolle Fähigkeit ist und daher weitere Studien durchgeführt werden müssen, um zu einer allgemeinen Schlussfolgerung zu gelangen.
description: Cooperation is important for survival and reputation formation is a key component of group-living animals that can facilitate cooperation. Reputations can be formed through direct experience or indirect experience, also called eavesdropping. Eavesdropping is an information-gathering process by observing third-party interactions. Dogs (Canis lupus familiaris) are a good model species for studying eavesdropping as they can cooperate with humans. Based on the mixed results of previous studies, we aimed to investigate whether pet dogs can form indirect reputations in a food-giving situation using human-animal interactions, where a generous person feeds the dog and a selfish person does not. We also tested whether older dogs with more life experience might be more likely to eavesdrop than younger dogs. We found no support for our hypothesis that dogs can form reputations about unfamiliar humans in a food-giving situation by eavesdropping, nor were there any differences between age groups. Our study shows that indirect reputation formation is a cognitively demanding skill and therefore further studies need to be conducted to reach a general conclusion.
title: Der Status von TranslatorInnen auf dem Arbeitsmarkt in der Republik Serbien

description: Die vorliegende Masterarbeit hat zum Ziel, folgende Forschungsfragen zu beantworten: Wer sind TranslatorInnen in Serbien und was ist charakteristisch für sie? Welche sind Besonderheiten des serbischen Arbeitsmarktes für TranslatorInnen? Welchen Status haben TranslatorInnen auf dem serbischen Arbeitsmarkt und welche Faktoren können zur Verbesserung ihres Status beitragen? Da für die Forschungsfragen dieser Masterarbeit und ihre spezifischen Fragestellungen eine quantitative, möglichst repräsentative Befragung sinnvoll war, wurde im Rahmen dieser Arbeit eine schriftliche Online-Befragung von TranslatorInnen mit Wohnsitz in der Republik Serbien durchgeführt. Basierend auf den Ergebnissen dieser Untersuchung wurde ein klareres Bild darüber erhalten, wer TranslatorInnen auf dem serbischen Arbeitsmarkt sind und was sie besonders auszeichnet. Es lässt sich aus der durchgeführten Studie auch schließen, dass sich die Bedingungen auf dem serbischen Arbeitsmarkt für DolmetscherInnen und ÜbersetzerInnen im Vergleich zu den Vorjahren nicht wesentlich verändert haben. Weiterhin konnte festgestellt werden, dass der Status serbischer DolmetscherInnen und ÜbersetzerInnen im Allgemeinen schlecht ist und dass es viel Raum für Verbesserungen gibt. Letztendlich ließ sich festhalten, dass eine bessere gesetzliche Regulierung der translatorischen Tätigkeit nach Meinung der Befragten die größte Rolle zur Verbesserung ihres Status auf dem serbischen Arbeitsmarkt spielen würde.

description: This document, aimed to predict the contribution of glaciers to sea level rise, has been carried out as part of Task 6.4 - Natural hazards in the Arctic. This deliverable describes a modelling-based approach developed by Universidad Politécnica de Madrid (UPM) to quantify the partitioning of solid ice discharge into its two main components, namely iceberg calving and submarine melting. For Greenlandic glaciers, it can take advantage of using, as part of its input data, those produced by the freshwater runoff product developed by the Geological Survey of Greenland and Denmark (GEUS), and the modelling-based estimates of solid ice discharge (obtained as sum of iceberg calving and submarine melting) can be validated against those produced by the solid ice discharge product developed by GEUS. This deliverable is conceived as a demonstration to stakeholders, who, in our case, are primarily researchers interested in estimating the current contribution of glacier wastage to sea-level rise and the future projections of such contributions under various scenarios of greenhouse gasses emissions. The demonstration is based on a video (ca. 20 min.) available through the INTAROS YouTube channel and the education material available though the INTAROS website. There is also a shorter version (a trailer, ca. 4 min.) of the video, aimed to provide an overview of the contents of the longer version. This written report provides a more detailed account of the coupled glacier dynamics-fjord circulation model in which the procedure for partitioning the ice discharge into its main components is based. Alternatively, there is a simpler version of the model, which is a coupled glacier dynamics-buoyant plume model that greatly reduces the computation time, while still providing sufficiently accurate results. The glacier dynamics model is defined by the Stokes system of partial differential equations, an associated constitutive relationship, together with an iceberg calving model, and is solved using the finite-element ELMER/Ice code. The fjord circulation (and submarine melting) model is defined by Boussinesq form of the Navier-Stokes equation set, plus the Holland and Jenkins equations defining the thermodynamic equilibrium at the fjord-glacier front interface and dissolved using the finite-volume MITgcm code. The plume parameterization model that replaces the fjord circulation model in the simplified version of the coupled model is programmed using MATLAB.
title: Vergeschlechtlichte Aspekte von Racial Profiling

description: Es gibt nur wenige Studien und wissenschaftliche Arbeiten zum Thema Racial Profiling im deutschsprachigen Raum. Die meisten dieser Arbeiten konzentrieren sich auf das Polizieren von rassifizierten Männlichkeiten. Dies verdeckt die intersektionalen Aspekte polizeilicher Gewalt und lässt die Erfahrungen und Perspektiven von rassifizierten FLINTA Personen unberücksichtigt. Diese Masterarbeit gibt einen Einblick darüber, wie FLINTA Personen in Wien Racial Profiling erleben und analysieren. Dazu habe ich queerfeministische, intersektionale und antirassistische Perspektiven zum Thema rassistische Polizeigewalt herausgearbeitet und anhand dieser die Institution Polizei und die polizeiliche Praxis des Racial Profilings untersucht und kontextualisiert. Um vergeschlechtlichte Aspekte rassistischer Polizeikontrollen in diesem Rahmen zu analysieren, habe ich fünf problemzentrierte Interviews mit Frauen und nicht-binären Personen geführt, die rassistische Polizeigewalt in unterschiedlichem Ausmaß erleben. Anhand meiner theoretischen Auseinandersetzungen und der empirischen Analyse wird deutlich, dass rassistische Polizeikontrollen vergeschlechtlicht wirken und eine intersektionale Analyse der rassistischen Polizeigewalt unerlässlich ist, um das Erleben und die Auswirkungen dieser zu erfassen. Gleichzeitig wird deutlich, dass rassistische Polizeigewalt staatlich und somit strukturell verankert ist und es, um diese aufzulösen, neue gesellschaftliche Strukturen braucht, die - und Herrschaftsverhältnisse überwinden.
description: There are few studies and academic works on the topic of racial profiling in the German speaking context. Most of them focus on policing racialized masculinities. This disguises the intersectional aspects of police violence and leaves the experiences and perspectives of racialized FLINTAs unaddressed. This master’s thesis provides insights into how FLINTA persons in Vienna experience and analyze racial profiling. Therefore, I have elaborated queerfeminist, intersectional and anti-racist perspectives on the topic of racist police violence. I analyzed and contextualized the institution of the police and racist police controls according to this framework. To analyze gendered aspects of racial profiling controls, I conducted five problem-centered interviews with women and non-binary individuals who experience racialized police violence to varying degrees. Based on my theoretical arguments and empirical analysis, I state that racial profiling controls have a gendered effect and that an intersectional analysis of the police violence is vital to capture the experience and impact of it. At the same time, it becomes clear that racist police violence is state-based and thus structurally anchored, and that in order to dissolve it, new social structures are needed which overcome existing power and domination relations.

description: We compute masses of the two lightest glueballs from spectral reconstructions of timelike interaction channels of the four-gluon vertex in Landau gauge Yang-Mills theory. The Euclidean spacelike dressings of the vertex are calculated with the functional renormalisation group. For the spectral reconstruction of these Euclidean data, we employ Gaussian process regression. The glueball resonances can be identified straightforwardly and we obtain $m_{sc} = 1870(75)~$ MeV as well as $m_{ps} = 2700(120)~$ MeV, in accordance with functional bound state and lattice calculations.

description: Background: Before surgical or transcatheter aortic valve implantation (TAVI), coronary status evaluation is required. The role of combined computed coronary tomography angiography (cCTA) and TAVI planning CT in this context is not yet well elucidated. This study assessed whether relevant proximal coronary disease requiring coronary revascularization can be safely detected by combined cCTA and TAVI planning CT, including CT-derived fractional flow reserve (FFR) calculation in patients with severe aortic stenosis. Methods: This study analyzed patients with successful cCTA combined with TAVI planning CT using a 128-slice dual-source scanner. The detection via cCTA of relevant left main stem stenosis (>50%) or proximal coronary artery stenosis (>70%) was compared to invasive coronary angiography (ICA). Results: This study comprised 101 consecutive TAVI patients with a median age of 83 [77–86] years, a median STS score of 3.7 [2.4–6.1] and 54% of whom had known coronary artery disease. Of 15 patients with relevant coronary stenoses, 14 (93.3%) were detected with cCTA, while false positive results were found in 25 patients. Only in patients with previous percutaneous coronary stent implantation (PCI) were false positive rates (11/29) increased. In the subgroup without previous PCI, an improved classification performance of 87.5%, being mainly due to 11.1% false positive classifications, led to a negative predictive value of 98.5%. Conclusions: Combined cCTA and CT-FFR with TAVI planning CT via state-of-the-art scanners and protocols as a one-stop shop can replace routine ICA in patients prior to TAVI due to its safe detection of relevant coronary artery stenosis, although diagnostic performance of cCTA is only reduced in patients with coronary stents. © In Copyright http://rightsstatements.org/vocab/InC/1.0/

Our first result shows that the above characterization remains valid for a wide class of generalized rank functions, including e.g. the permanental rank. Our second result extends the characterization to bounded rank subspaces of the graphical alternating matrix space associated with a general graph.

description: The emergence of transition metal dichalcogenides (TMDs) as 2D electronic materials has stimulated proposals of novel electronic and photonic devices based on TMD heterostructures. Here we report the determination of band offsets in TMD heterostructures by using microbeam X-ray photoelectron spectroscopy (μ-XPS) and scanning tunneling microscopy/spectroscopy (STM/S). We determine a type-II alignment between $\textrm{MoS}_2$ and $\textrm{WSe}_2$ with a valence band offset (VBO) value of 0.83 eV and a conduction band offset (CBO) of 0.76 eV. First-principles calculations show that in this heterostructure with dissimilar chalcogen atoms, the electronic structures of $\textrm{WSe}_2$ and $\textrm{MoS}_2$ are well retained in their respective layers due to a weak interlayer coupling. Moreover, a VBO of 0.94 eV is obtained from density functional theory (DFT), consistent with the experimental determination.

description: In addition to zinc oxide-based cements, resin-based materials are also available for temporary cementation. The aim of this in vitro study was to determine the influence of the different material compositions on temporary bonds. In nine test series (n = 30), temporary bis-acrylate single-tooth crowns were bonded onto prefabricated titanium abutments with nine different temporary luting materials. After simulating an initial (24 h, distilled water, 37 °C), a short-term (7 days, distilled water, 37 °C) and a long-term provisional restoration period (12h, distilled water, 37 °C; thermocycling: 5000 cycles) in subgroups (n = 10), the bond strength was examined using a combined tensile–shear test. Statistical analysis was performed by univariate analysis of variance or a non-parametric Kruskal–Wallis test, followed by post hoc tests. Of the three resin-based materials, two showed significantly higher bond strength values compared to all other materials ( p < 0.001), regardless of the storage procedure. The resin-based materials were followed by eugenol-free and eugenol-containing zinc oxide materials. Significant intragroup differences were observed between the composite-based materials after all storage periods. This was only observed for some of the zinc oxide-based materials. The results show that under in vitro conditions, not only the composition of the temporary luting materials but also the different storage conditions have a significant influence on temporary bonds. © In Copyright http://rightsstatements.org/vocab/InC/1.0/

Equivalence testing for functional data with an application to comparing pulmonary function devices

Year: 2014

description: Equivalence testing for scalar data has been well addressed in the literature, however, the same cannot be said for functional data. The resultant complexity from maintaining the functional structure of the data, rather than using a scalar transformation to reduce dimensionality, renders the existing literature on equivalence testing inadequate for the desired inference. We propose a framework for equivalence testing for functional data within both the frequentist and Bayesian paradigms. This framework combines extensions of scalar methodologies with new methodology for functional data. Our frequentist hypothesis test extends the Two One-Sided Testing (TOST) procedure for equivalence testing to the functional regime. We conduct this TOST procedure through the use of the nonparametric bootstrap. Our Bayesian methodology employs a functional analysis of variance model, and uses a flexible class of Gaussian Processes for both modeling our data and as prior distributions. Through our analysis, we introduce a model for heteroscedastic variances within a Gaussian Process by modeling variance curves via Log-Gaussian Process priors. We stress the importance of choosing prior distributions that are commensurate with the prior state of knowledge and evidence regarding practical equivalence. We illustrate these testing methods through data from an ongoing method comparison study between two devices for pulmonary function testing. In so doing, we provide not only concrete motivation for equivalence testing for functional data, but also a blueprint for researchers who hope to conduct similar inference.

description: A $(d-1)$-dimensional simplicial complex is called balanced if its underlying graph admits a proper $d$-coloring. We show that many well-known face enumeration results have natural balanced analogs (or at least conjectural analogs). Specifically, we prove the balanced analog of the celebrated Lower Bound Theorem for pseudomanifolds and characterize the case of equality; we introduce and characterize the balanced analog of the Walkup class; we propose the balanced analog of the Generalized Lower Bound Conjecture and establish some related results. We close with constructions of balanced manifolds with few vertices.

description: High-dimensional quantum steering can be seen as a test for the dimensionality of entanglement, where the devices at one side are not characterized. As such, it is an important component in quantum informational protocols that make use of high-dimensional entanglement. Although it has been recently observed experimentally, the phenomenon of high-dimensional steering is lacking a general certification procedure. We provide necessary and sufficient conditions to certify the entanglement dimension in a steering scenario. These conditions are stated in terms of a hierarchy of semidefinite programs, which can also be used to quantify the phenomenon using the steering dimension robustness. To demonstrate the practical viability of our method, we characterize the dimensionality of entanglement in steering scenarios prepared with maximally entangled states measured in mutually unbiased bases. Our methods give significantly stronger bounds on the noise robustness necessary to experimentally certify high-dimensional entanglement.

description: We numerically demonstrate a practical means of systematically controlling topological transport on the surface of a three dimensional topological insulator, by introducing strong disorder in a layer of depth $d$ extending inward from the surface of the topological insulator. The dependence on $d$ of the density of states, conductance, scattering time, scattering length, diffusion constant, and mean Fermi velocity are investigated. The proposed control via disorder depth $d$ requires that the disorder strength be near the large value which is necessary to drive the TI into the non-topological phase. If $d$ is patterned using masks, gates, ion implantation, etc., then integrated circuits may be fabricated. This technique will be useful for experiments and for device engineering.

description: The disorder systems host three types of fundamental quantum states, known as the extended, localized, and critical states, of which the critical states remain being much less explored. Here we propose a class of exactly solvable models which host a novel type of exact mobility edges (MEs) separating localized states from robust critical states, and propose experimental realization. Here the robustness refers to the stability against both single-particle perturbation and interactions in the few-body regime. The exactly solvable one-dimensional models are featured by quasiperiodic mosaic type of both hopping terms and on-site potentials. The analytic results enable us to unambiguously obtain the critical states which otherwise require arduous numerical verification including the careful finite size scalings. The critical states and new MEs are shown to be robust, illustrating a generic mechanism unveiled here that the critical states are protected by zeros of quasiperiodic hopping terms in the thermodynamic limit. Further, we propose a novel experimental scheme to realize the exactly solvable model and the new MEs in an incommensurate Rydberg Raman superarray. This work may pave a way to precisely explore the critical states and new ME physics with experimental feasibility.

title: Das Werk des Malers Dionisij im Kloster Ferapontow
Creators: name: Kormosz, Martha
Year: 2022

description: Diese Masterarbeit untersucht das Bildkonzept der Mariä-Geburt-Kathedrale des Klosters Ferapontow, deren Fresken wegen des abgelegenen Standortes in einem guten Zustand erhalten geblieben sind. Die Wandmalereien und der Ikonostas wurden vom zu seinen Lebzeiten berühmten Ikonenmaler Dionisij und seinen Söhnen ausgeführt. Die Kathedrale des Klosters Ferapontow ist das älteste erhaltene Beispiel russischer Monumentalmalerei, das Darstellungen des Hymnos Akathistos und der ökumenischen Konzile enthält. Beide Themen stellten für die damalige Zeit eine Neuheit dar. Das Ziel dieser Arbeit ist der Vergleich der Fresken in Ferapontow mit möglichen Vorbildern für die neuen Themen, die in der herangezogenen Literatur kurz erwähnt wurden. Zu Beginn dieser Arbeit erfolgt eine Einführung in das Œuvre des Künstlers Dionisij und in die Entstehungsgeschichte des Klosters. Im Anschluss wird das Bildprogramm der Kathedrale analysiert. Dazu gehört auch die Interpretation der Inschrift, die über den Entstehungszeitraum und den ausführenden Künstler eine Auskunft gibt. Auf die Technik und die Farbigkeit der Fresken wird ebenfalls eingegangen. Auf das Kapitel über den Hymnos Akathistos folgen die Vorbilder, die in Frage kommen. Sie befinden sich in Griechenland und am Balkan.
description: This master’s thesis examines the iconographic concept of the Virgin Nativity Cathedral in the Ferapontow Monastery, whose frescoes are well preserved due to the remote location. The murals and the iconostasis were painted by the famous icon painter Dionisij and his sons. The cathedral of the Ferapontow Monastery is the oldest preserved example in the Russian Monumental Art, that represents visualisations of the Hymnos Akathistos and the ecumenical councils. Both topics were a novelty for that time. The aim of this thesis is to compare the frescoes in Ferapontow with potential examples for the origin of the new topics, which were mentioned in the consulted references. The first chapter of this thesis contains an introduction of Dionisij’s complete work and the origin history of the monastery. The next chapter includes an analysation of the iconographic concept. The interpretation of the inscription, which provides information about the date of origin of the wall paintings and the performing artist. The research about the technique and the coloration of the frescoes is as well part of the thesis. After the chapter about the Hymnos Akathistos follow the examples, which come into consideration as possible models. They are located in Greece and in the Balkans.

description: This paper provides examples of various synchronous and asynchronous signal processing systems for performing optimization, utilizing the framework and elements developed in a preceding paper. The general strategy in that paper was to perform a linear transformation of stationarity conditions applicable to a class of convex and nonconvex optimization problems, resulting in algorithms that operate on a linear superposition of the associated primal and dual decision variables. The examples in this paper address various specific optimization problems including the LASSO problem, minimax-optimal filter design, the decentralized training of a support vector machine classifier, and sparse filter design for acoustic equalization. Where appropriate, multiple algorithms for solving the same optimization problem are presented, illustrating the use of the underlying framework in designing a variety of distinct classes of algorithms. The examples are accompanied by numerical simulation and a discussion of convergence.

description: We study photo-assisted transport for the edge states of a two dimensional electron gas in the fractional quantum Hall regime, pinched by a single quantum point contact. We provide a general expression of the photo-assisted current using a Keldysh-Floquet approach, when the AC drive is applied either directly to the edge states, or when it modulates the tunneling amplitude at the quantum point contact. Strikingly, for a simple cosine modulation of the tunneling amplitude, the phase shift of the second harmonic of the photoassisted current is directly related to the scaling dimension of the quasiparticle operators describing the fractional excitations. As the scaling dimension is intimately related to the statistics, our proposal of a gate modulation of the backscattered current provides a diagnosis of the statistics of Laughlin quasiparticles using a simple quantum point contact geometry.

description: Silicon is indispensable in semiconductor industry. Understanding its high-temperature thermodynamic properties is essential both for theory and applications. However, first-principle description of high-temperature thermodynamic properties of silicon (thermal expansion coefficient and specific heat) is still incomplete. Strong deviation of its specific heat at high temperatures from the Dulong-Petit law suggests substantial contribution of anharmonicity effects. We demonstrate, that anharmonicity is mostly due to two transverse phonon modes, propagating in (111) and (100) directions, and can be quantitatively described with formation of the certain type of nanostructured planar defects of the crystal structure. Calculation of these defects' formation energy enabled us to determine their input into the specific heat and thermal expansion coefficient. This contribution turns out to be significantly greater than the one calculated in quasi-harmonic approximation.

description: Canonical partition functions and Lee-Yang zeros of QCD at finite density and high temperature are studied. Recent lattice simulations have confirmed that the free energy of QCD is a quartic function of quark chemical potential at temperature slightly above pseudo-critical temperature $T_c$, as in the case with a gas of free massless fermions. We present analytic derivation of the canonical partition functions and Lee-Yang zeros for this type of free energy using the saddle point approximation. We also perform lattice QCD simulation in a canonical approach using the fugacity expansion of the fermion determinant, and carefully examine its reliability. By comparing the analytic and numerical results, we conclude that the canonical partition functions follow the Gaussian distribution of the baryon number, and the accumulation of Lee-Yang zeros of these canonical partition functions exhibit the first-order Roberge-Weiss phase transition. We discuss the validity and applicable range of the result and its implications both for theoretical and experimental studies.
