Reservoir computing based on solitary-like waves dynamics of film flows: a proof of concept

description: Several theoretical works have shown that solitons -- waves that self-maintain constant shape and velocity as they propagate -- can be used as a physical computational reservoir, a concept where machine learning algorithms designed for digital computers are replaced by analog physical systems that exhibit nonlinear dynamical behaviour. Here we propose and experimentally validate a novel reservoir computing (RC) system that for the first time employs solitary-like (SL) waves propagating on the surface of a liquid film flowing over an inclined surface. We demonstrate the ability of the SL wave RC system (SLRC) to forecast chaotic time series and to successfully pass essential benchmark tests, including a memory capacity test and a Mackey-Glass model test.
Theater of Revolution and the Law of Genre – Bertolt Brecht’s The Measures Taken (Die Maßnahme)
Creators: name: Simons, Oliver

Year: 2009
Subjects: Theater

description: It has been emphasized frequently that Bertolt Brecht's political theater, Die Maßnahme in particular, has been influenced by Carl Schmitt's theory of the sovereign and the state of exception. Although it is indeed remarkable that his learning play seems to record some of the concepts that, in Schmitt, belong to the categories of political theory, this article will return to the role and discourse of the theater in Brecht. The drama of revolution is a political text through and through, but it cannot separate the political from the theater; the drama of revolution is in search of a form, a metatheater, in which the overcoming of an order is first and foremost the attempt to suspend the law of genre. Strikingly, Brecht's learning play brings to the stage all the characteristics that have, since Aristotle, marked tragedy: the pity, the error of a hero, the hero's comprehension of the error, the guilt of an innocent man, the hero's death, the sacrifice, and catharsis. Brecht reproduces the law of the genre he wishes to supersede and entangles his figures in inescapable aporias that have dominated the metadiscourse on drama in revolutionary theater from Büchner's Danton's Tod to Heiner Müller's Mauser.
“Amerika gibt es nicht” – On the Semiotics of Literary America in the Twentieth Century
Creators: name: Simons, Oliver

Year: 2009
Subjects: Literature
German literature

description: From Alexis de Tocqueville's arrival in Manhattan and his amazement at the artificial façades of houses on the East River, we can observe a specific semiotic model in depictions of America: America does not exist, which is to say, the referent often becomes questionable in these texts. All the more frequently descriptions of America hew to a metonymic mode of writing; they deal with signs which refer to other signs, with accounts reporting mostly what has been read elsewhere. With Franz Kafka and Wolfgang Koeppen this essay shows how America has become the setting of poetological self-determination; America is a textual construct in which the significatory nature of language is itself negotiated. Under these conditions, how can another America novel be written at the end of the 20th-century? In the concluding passages, this essay discusses how contemporary authors Thomas Meinecke and Michael Roes succeed in resurrecting America's narrative possibilities.
A Short History of Tontines
Creators: name: McKeever, Kent
Publisher: name: Columbia University
Year: 2009
Subjects: subject: Law
subject: FOS: Law

description: A tontine is an investment scheme through which shareholders derive some form of profit or benefit while they are living, but the value of each share devolves to the other participants and not the shareholder's heirs on the death of each shareholder. The tontine is usually brought to an end through a dissolution and distribution of assets to the living shareholders when the number of shareholders reaches an agreed small number. If people know about tontines at all, they tend to visualize the most extreme form - a joint investment whose heritable ownership ends up with the last living shareholder. The all or nothing nature of that form is memorable. The last survivor principle has been the basis for a number of dramatic works whose plots hang on the machinations of a tontine participant to murder his co-investors to insure the core property reverts to him. In fact, tontines are far more innocuous and served as an important step both in developing modem insurance plans and providing some of the earliest reliable actuarial data on which the later insurance plans could be developed. Since tontines have been neglected for many years, this Essay is primarily concerned with providing background information. It covers the history of their development and the broad variety of uses they have served from the 17th to the early 20th centuries. It concludes with a brief exploration of the revival of the tontine as a possible addition to the range of modem financial tools.
CMB Power Asymmetry from Primordial Sound Speed Parameter

description: The hemispherical power asymmetry in the cosmic microwave background may be explained by the modulation of some primordial cosmological parameter, such as the sound speed of the inflaton. This modulation can be achieved by the perturbation of a light field during inflation. We numerically examine this mechanism and show it can be consistent with current observations. Further, this model predicts that the power asymmetry also exists in the temperature-polarization correlation and polarization autocorrelation with the same shape, and in primordial non-gaussianity of equilateral type with a particular shape. Therefore, our mechanism is observationally detectable in forthcoming experiments.

Kanamori-Moiré-Hubbard model for transition metal dichalcogenide homobilayers

description: Ab-initio and continuum model studies predicted that the $Γ$ valley transition metal dichalcogenide (TMD) homobilayers could simulate the conventional multi-orbital Hubbard model on the moiré Honeycomb lattice. Here, we perform the Wannierization starting from the continuum model and show that a more general Kanamori-Moiré-Hubbard model emerges, beyond the extensively studied standard multi-orbital Hubbard model, which can be used to investigate the many-body physics in the $Γ$ valley TMD homobilayers. Using the unrestricted Hartree-Fock and Lanczos techniques, we study these half-filled multi-orbital moiré bands. By constructing the phase diagrams we predict the presence of an antiferromagnetic state and in addition we found unexepected and dominant states, such as a S = 1 ferromagnetic insulator and a charge density wave state. Our theoretical predictions made using this model can be tested in future experiments on the $Γ$ valley TMD homobilayers.

Establishing and Evaluating Climate Change Heuristics of Multi-Actor Professional Leadership in the New York Metropolitan Region

description: This article sets out to evaluate the existing range of heuristics and preferences for the concepts of adaptation, resilience, mitigation and coping of a variety of actors in the metropolitan region of New York City who are undertaking professional leadership positions in developing policies and practices which address a multitude of risks associated with climate change. Prior interviews and observations have suggested that the inconsistent usage of these concepts—including, the rhetorical application of resilience as a leading framework—are thwarting the development of planning instruments and decision tools. This article positions a normative set of meanings for each of the aforementioned concepts based on a review of existing literature. Then, utilizing a survey, these normative meanings are evaluated by and between the: (i) concepts and meanings; (ii) concepts and applications; and, (iii) applications and preferences, as applied to various risk based scenarios ranging from sea level rise to heat waves. This survey tests the hypotheses that the respondents: (a) are unable to consistently match the concept of resiliency with the normative meanings or applications: and, (b) will not consistently show a preference for resilience applications or outcomes ahead of other concepts. The results of the survey confirm both hypotheses, which is demonstrative of the inadequacy of the current framework dominated by resilience in its rhetorical form. It is anticipated that the results of this article will advance an argument for the necessity to develop consistent meanings for concepts which bridge the scientific, policy and popular domains.
Fully-Adaptive and Semi-Adaptive Frequency Sweep Algorithm Exploiting Loewner-State Model for EM Simulation of Multiport Systems

description: This paper employs a fully adaptive and semi-adaptive frequency sweep algorithm using the Loewner matrix-based state model for the electromagnetic simulation. The proposed algorithms use two Loewner matrix models with different or the same orders with small frequency perturbation for adaptive frequency selection. The error between the two models is calculated in each iteration, and the next frequency points are selected to minimize maximum error. With the help of memory, the algorithm terminates when the error between the model and the simulation result is reached within the specified error tolerance. In the fully adaptive frequency sweep algorithm, the method starts with the minimum and maximum frequency of simulation. In the semi-adaptive algorithm, a novel approach has been proposed to determine the initial number of frequency points necessary for system interpolation based on the electrical size of the structure. The proposed algorithms have been compared with the Stoer-Bulirsch algorithm and Pradovera's minimal sampling algorithm for electromagnetic simulation. Four examples are presented using MATLAB R2024b. The results show that the proposed methods offer better performance in terms of speed, accuracy and the requirement of the minimum number of frequency samples. The proposed method shows remarkable consistency with full-wave simulation data, and the algorithm can be effectively applicable to electromagnetic simulations.

description: In the final decade of the 19th century, the temperance movement was gaining ground fast in the Estonian society. The same could not be said about the local elite, the Baltic Germans. The reluctance of the ‘genteel folk’ is noteworthy, if only for the reason that Gustav Piers von Bunge (1844–1920), one of the leading proponents of the medical temperance movement at the turn of the century, was one of their own, although he spent most of his life at the University of Basel in Switzerland. Bunge tried to spread his progressive ideas about healthcare in his homeland, encouraging the Baltic Germans to follow the example of Estonians and Latvians. Baltic German women were the first to embrace temperance. On the cusp of World War I, the local German medical professionals started to pay more attention to the idea, but remained more moderate in comparison to Bunge, declaring that each individual should decide for themselves whether they imbibe alcohol or not. In conclusion it can be claimed that the Baltic German’s reticence towards temperance arose from the economic losses this caused to their circles (the state’s vodka monopoly did away with the right to keep taverns), but especially from the political background of the temperance movement. The Estonian temperance movement had an important role in this, as it became a part of the national agenda.

description: This research overview reviews recent findings on transfer from community colleges to four-year institutions, including student transfer patterns, student outcomes, barriers to transfer, the economic benefits of transfer, and the potential benefits of vertical transfer for four-year colleges and universities. Overall, the returns to transfer are strong, and transfer offers a vital route to a bachelor’s degree for many underserved students. However, there are significant barriers to transfer—particularly the loss of credits many community college students experience when they transition to four-year institutions. Improving the transfer process and ensuring students can transfer credits efficiently has the potential to substantially raise college attainment and thereby contribute to upward mobility.
Recent Developments at the Columbia University Computer Music Center

description: Columbia University has had a long involvement with music technology, establishing one of the first, if not the first, research/music centers devoted to electronic music in the United States. Officially recognized in the late 1950s as the Columbia-Princeton Electronic Music Center, the EMC was a hotbed of musico-technological work in the ensuing decades. A few years ago I became Director of the Center-its new advisory board comprising Fred Lerdahl, Tristan Murail, and myself. We managed to secure a sizable boost in funding from the Columbia University Administration and from several external sources, and with this influx of new support we decided to rebuild a number of our studios and to undertake a major overhaul and revamping of the Center's facilities. We also decided to rethink the operation of the Center, seeking to renew the status it enjoyed for decades as an advanced and progressive workplace for musicians and researchers who use new music technologies. At that time we officially changed the name from the Electronic Music Center to the Computer Music Center (CMC) to better reflect the new organizational structure as well as the renewed research/music focus. Dan Thompson asked if I would write a description of some of the changes that have taken place at the CMC for Current Musicology. Rather than merely describing hardware and software projects, I thought it might be more interesting for me to try to articulate my version of the philosophy driving what we now do at the CMC. The operation of the CMC is indeed a personal odyssey for everyone involved. What I describe is truly my own version of how the Center is, and it may or may not reflect the actual reality of the CMC.

Spooning Good Singing Gum: Meaning, Association, and Interpretation in Rock Music
Creators: name: Jackson, Travis A.
Publisher: name: Columbia University
Year: 2000
Subjects: Music

description: Since at least the early 1950s, scholars and critics from widely varying backgrounds have attempted to come to terms with the musics collectively known as "rock," returning again and again to the issue of meaning. Predictably, their answers to the implied question are as varied as their intellectual standpoints. Some scholars, for example, have viewed rock through the lenses of mass and youth culture, drawing on the work of Theodor Adorno and a large body of sociological writing. Others, coming to rock from cultural studies and literary theory, have conceptualized it as a series of "texts" that comment on and reflect current debates on cultural identity, hegemony, resistance, gender and sexuality (Frith and Goodwin 1990; Hesmondhalgh 1996). Writers for the popular press, meanwhile, have tended to focus on issues of authenticity, originality and rebellion, particularly in canonizing iconic figures like Elvis Presley, Sid Vicious, or Kurt Cobain. In reading all this work, some fans or aficionados of rock (including scholars and critics) are likely to be dissatisfied. To them it might seem that (other) rock commentators are either focusing on too narrow a portion of the musical landscape-discussing it in ways that render it nearly unrecognizable-or missing the point of the music altogether. Whatever the point, to such fans rock is potentially about more than youth culture, the (re)production of ideology, or authenticity and rebellion. The question, of course, is what "more" there might be and, relatedIy, how one gains access to and talks about it.

description: Microresonator-based optical frequency combs have been a topic of extensive research during the last few years. Several theoretical models for the comb generation have been proposed; however, they do not comprehensively address experimental results that show a variety of independent comb generation mechanisms. Here, we present frequency-domain experiments that illuminate the transition of microcombs into phase-locked states, which show characteristics of injection locking between ensembles of comb modes. In addition, we demonstrate the existence of equidistant optical frequency combs that are phase stable but with non-deterministic phase relationships between individual comb modes.

Publisher: name: Columbia University

Subjects: Music

description: It is a commonplace of history that we do not encounter events from the past, but rather descriptions of these events. To be more contemporary, and perhaps more accurate, we encounter "spins" on the events. While a kind of precise objectivity based on careful duplication of experiments may be prized by the "hard" sciences, most historians today do not believe that such things as "the past" or "culture" will yield to such treatment. The more we seek to "pin down" an event, to argue for a document's "authentic" privileging, the more any kind of objective truth may recede, to be replaced by yet another false front. It is, of course, not necessarily the facts which are in doubt in a particular case, but how they are assembled, organized and presented. The reality of the past, if it appears to us at all, does so through what some have called the "convergence of evidence," and always requires a leap of faith on the part of any investigator or beholder. If this is true of history in general, it must also be true for the written history of polar exploration, something which, surprisingly, has captured the imagination of the reading public. Some stories tell better than others, and there has always been a tension between the desire to write history and the storytelling urge, where the requirements of crafting a good yarn do battle with the desire to "get it right." We shall argue here that the same is true when we attempt to understand music and musical meaning. As we take this journey, our guide will be a work "set," as it were, in the cold deserts of Antarctica, a piece that has had something of a mixed reception from audiences and critics-a possibly ambivalent symphony about an ambiguous hero.

Namely elastic scatterings of hadrons are considered in this paper. The general machinery of their theoretical treatment is described. Some new experimental data are presented and confronted to phenomenological approaches. The internal structure of hadrons is the main subject of these studies. Its impact on properties of their interactions is reviewed. It is shown that protons become larger and darker with increase of their collision energy and reveal some substructure. The violation of the geometric scaling in the diffraction cone and new problems of description of differential cross sections outside it are described.

This policy brief of the CoAct Research and Innovation Action #2 Youth Employment summarises the findings and recommendations originating from the co-research process with young people in employment measures in Vienna (Austria). The recommendations for policy makers focus on the “AusBildung bis 18” (Education and Training up to 18) programme, which was established in 2016. The young co-researchers demanded a more inclusive and accessible labour market for young people and that policy makers take measures to remove barriers to their educational careers in terms of discrimination, racism, and mental health issues. A key message is that young people must be involved in designing the measures and policies that affect them in order to create and design services that best support them on their path to education and employment.

Patricia Carpenter in Commemoration

description: As research scholars, we are known for our students as much as by our publications. Patricia Carpenter's published writings, listed at the end of this tribute, constitute a mayor contribution to music theory and aesthetics. But her many students, a few of whom are represented in this commemoration, measure her legacy. As these memorial sketches reveal, she shaped countless students during her twenty-six years at Barnard College and Columbia University. For Pat, scholarly investigation was inextricable from teaching: everything tendered in the classroom was subject to the same scrutiny she brought to her own research. Everything she set before us as students around the long grey tables in Dodge Hall was a commitment as earnest as any address before a forum of learned colleagues. And from all of us she demanded the same high standard that she demanded of herself: endless curiosity tempered by unflagging criticism. In this regard, her students were indivisible from her publications, each formed rigorously to become a self-standing component in the broad intellectual circle that was Patricia Carpenter.

description: A theory of Bose-Einstein condensation (BEC) of light in a dye microcavity is developed. The photon polarization degeneracy and the interaction between dye molecules and photons in all of the cavity modes are taken into account. The theory goes beyond the grand canonical approximation and allows one to determine the statistical properties of the photon gas for all numbers of dye molecules and photons at all temperatures, thus describing the microscopic, mesoscopic, and macroscopic light BEC from a general perspective. A universal relation between the degrees of second-order coherence for the photon condensate and the polarized photon condensate is obtained. The photon Bose-Einstein condensate can be used as a new source of nonclassical light.

description: The advent of the Internet of Things (IoT) forces incumbent firms to reshape their organizational structures toward platform ecosystems. However, prior research lacks concrete insights about how incumbent firms can foster value co-creation to become ecosystem orchestrators. In particular, it only sheds little light on the complex challenges incumbents face in designing and governing IoT platform ecosystems. In response, we present a single case study describing how the departments of Robert Bosch GmbH, a leading IoT company, overcame these challenges in three dimensions IoT ecosystem, IoT platform, and value co-creation. We tie in our research with the existing body of literature, identify four prevailing tensions in ecosystem establishment, and provide actionable design and governance recommendations to resolve them.

description: Policymakers have become increasingly concerned with measuring--and holding colleges accountable for--students’ labor market outcomes. In this paper we introduce a piecewise growth approach to analyzing community college students’ labor market outcomes, and we discuss how this approach differs from Mincerian and fixed-effects approaches. Our results suggest that three assumptions underpinning traditional approaches may not be well founded. We then highlight how insights gained from the growth curve approach can be used to strengthen evolving econometric analyses of labor market returns, as well as to improve the accuracy and usefulness of the relatively simple models required by policymakers and practitioners.

Detection of X-ray polarized emission and accretion-disk winds with IXPE and NICER in the black-hole X-ray binary 4U 1630-47

description: We detect a high level of polarization in the X-ray emission of the black-hole binary 4U 1630-47 in an observation with the Imaging X-ray Polarimetry Explorer. The 2-8 keV polarization degree is 8 % at a position angle of $18^\circ$, with the polarization degree increasing significantly with energy, from ~6 % at ~2 keV to ~ 11 % at ~8 keV. The continuum emission in the spectrum of simultaneous observations with the Neutron Star Interior Composition Explorer, NICER, is well described with only a thermal disc spectrum, with stringent upper limits to any Comptonized emission from the corona. Together with the lack of significant variability in the Fourier power spectrum, this suggests that the source was in the high-soft state at the time of these observations. The NICER spectrum reveals the presence of several absorption lines in the 6-9 keV band that we fit with two ionized absorbers, providing evidence of the presence of a strong disk wind, which supports the idea that the source was in the soft state. Previous measurements of X-ray polarization in other sources in harder states were associated with the corona or the jet in those systems. Given that the corona is significantly absent in this observation of 4U 1630-47, and that the jet in black-hole binaries is quenched in the high-soft state, we speculate that in this observation of 4U 1630-47, the polarization likely arises from the direct and reflected radiation of the accretion disk in this source.

description: We introduce an iterative spectral disentangling technique combined with Doppler imaging in order to recover surface temperature maps for both components of double-lined active binary systems. Our method provides an opportunity to separate spectra of the active components while minimizing the unwanted disturbances on the given line profile from the other component. The efficiency of the method is demonstrated on real data of the double-lined RS CVn-type binary V824 Ara. The resulting Doppler images reveal cool spots on the polar regions as well as low-latitude features on both of the stars. Moreover, both components have hot spots, that are facing each other. This may indicate interconnection between the stellar magnetic fields.

Ziel der Erhebungen war es, Risikofaktoren für eine Verzögerung der Studiendauer einen Studienabbruch als auch Resilienzfaktoren zu identifizieren. Wartezeitstudierende im vorklinischen Studienabschnitt wurden in Einzelinterviews befragt und bis zu definierten Endpunkten begleitet. Parallel wurden Merkmale des Persönlichkeitsinventars erhoben. Die persönliche Motivation und ein ehrgeiziges Persönlichkeitsprofil scheinen erfolgsprädiktiv für den Studienverlauf zu sein.

The Labor Market Returns to Math Courses in Community College

description: This paper examines the returns to math courses relative to courses in other subjects for students in community college. Using matched college transcript and earnings data on over 80,000 students entering community college during the 2000s, we find that college-level math coursework has an indirect positive effect on award completion that is stronger than that of coursework in other subjects. In terms of direct effects, we find mixed evidence on the direct effect of enhanced math skills on earnings over other college-level skills. Overall, the combined direct and indirect effect appears to be adverse: compared with other courses or college pathways, more math coursework in community college is modestly associated with relatively lower earnings in later adulthood. However, this association is sensitive to modeling, and we do find heterogeneous results by gender, race/ethnicity, and initial college ability, as well as by math field and level.
Algebraic Diagrammatic Construction Theory for Simulating Charged Excited States and Photoelectron Spectra

description: Charged excitations are electronic transitions that involve a change in the total charge of a molecule or material. Understanding the properties and reactivity of charged species requires insights from theoretical calculations that can accurately describe orbital relaxation and electron correlation effects in open-shell electronic states. In this perspective, we review the current state of algebraic diagrammatic construction (ADC) theory for simulating charged excitations and its recent developments. We start with a short overview of ADC formalism for the one-particle Green's function, including its single- and multireference formulations and extension to periodic systems. Next, we focus on the capabilities of ADC methods and discuss recent findings about their accuracy for calculating a wide range of excited-state properties. We conclude our perspective by outlining possible directions for future developments of this theoretical approach.

description: This report, published by the Center for Minority Serving Institutions in collaboration with CAPSEE, looks at the role of two-year Minority Serving Institutions (MSIs) in improving postsecondary access and degree completion for disadvantaged students in the United States. In doing so, it aims to prepare the groundwork for research that considers the contributions of two-year MSIs on their own terms, as a distinct and crucial institutional type on the landscape of American higher education. The report addresses the following questions: What are two-year MSIs? Who attends them? Where are they located? How do they contribute to educational attainment and the workforce? What are the critical and unanswered questions that might move our understanding of two-year MSIs beyond mere descriptions and anecdotes?
