Pontische Mehrdeutigkeiten

Subjects: subject: 900 Geschichte und Geografie::900 Geschichte

description: Eines der griechischen Wörter für ‚Meer‘, ‚πόντος‘ (das zugleich ‚Kreuzen‘ und ‚Schwierigkeit‘ bedeutet), wurde seit archaischer Zeit für das Meer par excellence, den Pontos Euxeinos, verwendet. Von diesem Raum aus ging der Name zuerst auf die südöstliche Küste des Schwarzen Meeres und dann auf das Territorium des Reiches Mithridates Eupators und die römischen Provinzen Pontus über. Trotz dieser eindeutigen Chronologie bei der Verwendung des Namens Pontus für die genannten geographischen Gebiete weisen einige Inschriften Mehrdeutigkeiten auf. Eine als ‚Pontier‘ im Athen des 4. Jahrhunderts v. Chr. bezeichnete Person kann weder zu einem ‚pontischen‘ Volk noch zum Gebiet des mithridatischen Reiches gehört haben. Auch konnte eine ‚pontische‘ Frau des 2. Jahrhunderts v. Chr. aus dem Nordosten Kleinasiens oder aus Herakleia oder einer anderen Stadt des Schwarzen Meeres kommen. Ein junger Mann, gestorben in Rom zwischen dem 2. und dem 3. Jahrhundert, kam zwar aus der pontischen Provinz, aber sein Grabstein, der ihn als Landsmann des homerischen Helden Achilles darstellt, weckt Zweifelt an seiner Herkunft aus dem Schwarzmeerraum. In allen genannten Fällen ist das poetisch eingesetzte Adjektiv ‚pontisch‘ nicht nur als Hinweis auf eine unscharfe geographische Identität zu verstehen sondern beinhaltet darüber hinaus deutliche religiöse – maritime und erotische – Anspielungen.

description: We prove the existence of a Lax pair for the Calogero Korteweg-de Vries (CKdV) equation. Moreover, we modify the T operator in the the Lax pair of the CKdV equation, in the search of a (2+1)-dimensional case and thereby propose a new equation in (2+1) dimensions. We named this the (2+1)-dimensional CKdV equation. We show that the CKdV equation as well as the (2+1)-dimensional CKdV equation are integrable in the sense that they possess the Painlevé property. Some exact solutions are also constructed.

description: The urgent need for effective therapeutic interventions against SARS-CoV-2 has prompted extensive exploration of potential drug candidates. Among the viral proteins, the spike (S) protein presents an attractive target due to its critical role in viral entry and infection. In this study, we employed molecular docking techniques to investigate the binding affinities and interaction profiles of a panel of active compounds against the SARS-CoV-2 spike protein. Utilising computational simulations, we assessed the binding properties of these compounds within the receptor-binding domain (RBD) and other key regions of the spike protein. Our comparative analysis elucidates the differential binding patterns and identifies promising lead compounds with high binding affinity and favourable interaction profiles. Furthermore, we discuss the implications of these findings for the development of potential therapeutics targeting the SARS-CoV-2 spike protein. Using molecular docking and the Lipinski five rule, this study illustrates possible compounds with strong binding affinities, their molecular interactions, for both naturally occurring and man-made drugs. Computational approach is applied, and it is concluded that, drugs like Withanolide, Dihydroergocristine, Fenebrutinib, and Ergotamine shows binding energies between −8.3 and −9.1 kcal/mol, and are possible candidate for anti covid drug.

description: Estimators $Πn$ for the correlation energy can be computed as roots of effective characteristic polynomials of degree $n$. The coefficients of these polynomials are derived from the terms of the perturbation series of the energy. From a fourth-order Møller-Plesset (MP4) calculation one can calculate with negligible effort a size-extensive estimator $Π2$ that is in many cases much closer to the full CI correlation energy of the ground state than the MP4 value. [H.H.H. Homeier, J. Mol. Struct. (Theochem) 366, 161 (1996)] Here, we prove that the estimators $Πn$ for $n>2$ are size-extensive if they are calculated from the MP series.

description: Transformations between different analytic descriptions of constant mean curvature (CMC) surfaces are established. In particular, it is demonstrated that the system \[ \begin{split} &\partial ψ_{1} = (|ψ_{1}|^{2} + |ψ_{2}|^{2}) ψ_{2} \\ &\bar{\partial} ψ_{2} =- (|ψ_{1}|^{2} + |ψ_{2}|^{2}) ψ_{1} \end{split} \] descriptive of CMC surfaces within the framework of the generalized Weierstrass representation, decouples into a direct sum of the elliptic Sh-Gordon and Laplace equations. Connections of this system with the sigma model equations are established. It is pointed out, that the instanton solutions correspond to different Weierstrass parametrizations of the standard sphere $S^{2} \subset E^{3}$.
Casting Bread Upon the Waters:  American Farming and the International Wheat Market, 1880-1920
Creators: Popescu, Adina
Publisher: name: Columbia University
Year: 2013
Subjects: History

description: In the late 19th and early 20th century, as wheat production and marketing were transformed in scale and in practice, American farmers tried to make sense of how they were positioned within a rapidly growing and changing international market. They tried to formulate a response that would gain them some sense of control over a market that was described by some as vast and powerful as nature itself, and by others as a playground for the wealthy speculators who supposedly controlled it. By situating the farmers within the changing international grain market this thesis explains the challenges that they were up against. American farmers understood their plight through narratives of market failure, common enough during the agricultural depression of the 1890s, as well as in the first decade of the twentieth century: declining prices, distant famines, and attempts to corner the wheat market reinforced the notion that supply and demand were not working "properly" to produce prosperity for all. During the Populist period, farmers organized to demand relief, in the form of government intervention, from what they perceived as a predatory market system that guaranteed profits to speculators but usually left producers with little to show for their labor. They mounted a moral critique of the marketing system, arguing that merchants and middlemen had organized the market in such a way as to control it through unethical and damaging means such as pools and price agreements. These efforts having largely failed, farmers turned increasingly to the cooperative movement to try to exert influence in the marketplace.  The crisis of World War I created a different kind of market failure, one that prompted different forms of government intervention in both wheat importing and wheat exporting countries. In both cases these interventions were designed to stabilize prices through centralized oversight, something the farmers had repeatedly asked for and failed to achieve, but found, in the end, did little to secure their way of life. In the aftermath of war, in what was for wheat farmers a permanent crisis requiring permanent government intervention, farmers continued to identify the middlemen as their problem, but after 50 years of controversy, the merchants and exchanges had established a relatively well-oiled and highly technical system of marketing and trading to handle commodities in an international market. Farmers were left with little choice but to think of themselves as businessmen dealing with other businessmen, and this position overtook the older moral discourse as farmers sought to marshal their cooperative strength toward forming their own price-controlling marketing organizations.

description: We present a description of the moduli space of holomorphic vector bundles over Riemann curves as a double coset space which is differ from the standard loop group construction. Our approach is based on equivalent definitions of holomorphic bundles, based on the transition maps or on the first order differential operators. Using this approach we present two independent derivations of the Hitchin integrable systems. We define a "superfree" upstairs systems from which Hitchin systems are obtained by three step hamiltonian reductions. A special attention is being given on the Schottky parameterization of curves.

The Racah Algebra as a Subalgebra of the Bannai-Ito Algebra

Subjects: subject: Rings and Algebras (math.RA)

description: Assume that ${\mathbb F}$ is a field with $\operatorname{char}{\mathbb F}\not=2$. The Racah algebra $\Re$ is a unital associative ${\mathbb F}$-algebra defined by generators and relations. The generators are $A$, $B$, $C$, $D$ and the relations assert that $[A,B]=[B,C]=[C,A]=2D$ and each of $[A,D]+AC-BA$, $[B,D]+BA-CB$, $[C,D]+CB-AC$ is central in $\Re$. The Bannai-Ito algebra $\mathfrak{BI}$ is a unital associative ${\mathbb F}$-algebra generated by $X$, $Y$, $Z$ and the relations assert that each of $\{X,Y\}-Z$, $\{Y,Z\}-X$, $\{Z,X\}-Y$ is central in $\mathfrak{BI}$. It was discovered that there exists an ${\mathbb F}$-algebra homomorphism $ζ\colon \Re\to \mathfrak{BI}$ that sends $A \mapsto \frac{(2X-3)(2X+1)}{16}$, $B \mapsto \frac{(2Y-3)(2Y+1)}{16}$, $C \mapsto \frac{(2Z-3)(2Z+1)}{16}$. We show that $ζ$ is injective and therefore $\Re$ can be considered as an ${\mathbb F}$-subalgebra of $\mathfrak{BI}$. Moreover we show that any Casimir element of $\Re$ can be uniquely expressed as a polynomial in $\{X,Y\}-Z$, $\{Y,Z\}-X$, $\{Z,X\}-Y$ and $X+Y+Z$ with coefficients in ${\mathbb F}$.

description: We study the disordered, multi-spiral solutions of two-dimensional homogeneous oscillatory media for parameter values at which the single spiral/vortex solution is fully stable. In the framework of the complex Ginzburg-Landau (CGLE) equation, we show that these states, heretofore believed to be static, actually evolve on ultra-slow timescales. This is achieved via a reduction of the CGLE to the evolution of the sole vortex position and phase coordinates. This true defect-mediated turbulence occurs in two distinct phases, a vortex liquid characterized by normal diffusion of individual spirals, and a slowly relaxing, intermittent, ``vortex glass''.

description: I examine the effect of cash holdings on the relationship between cash flow volatility and corporate investment.  My results call into question the long-assumed negative association between cash flow volatility and corporate investment.  Using an expanded dataset of U.S. domestic firms, I show that firms with high cash holdings increase investment in the face of increasing cash flow volatility, whereas firms with low cash holdings lower their investment expenditure.  In doing so, I provide empirical evidence in support of recent theoretical models predicting that the sensitivity of investment to cash flow volatility is dependent on the level of balance sheet cash holdings.  My results are robust to a number of model specifications.

description: Using remarkably simple experimental techniques it is possible to gently break a metallic contact and thus form conducting nanowires. During the last stages of the pulling a neck-shaped wire connects the two electrodes, the diameter of which is reduced to single atom upon further stretching. For some metals it is even possible to form a chain of individual atoms in this fashion. Although the atomic structure of contacts can be quite complicated, as soon as the weakest point is reduced to just a single atom the complexity is removed. The properties of the contact are then dominantly determined by the nature of this atom. This has allowed for quantitative comparison of theory and experiment for many properties, and atomic contacts have proven to form a rich test-bed for concepts from mesoscopic physics. Properties investigated include multiple Andreev reflection, shot noise, conductance quantization, conductance fluctuations, and dynamical Coulomb blockade. In addition, pronounced quantum effects show up in the mechanical properties of the contacts, as seen in the force and cohesion energy of the nanowires. We review this reseach, which has been performed mainly during the past decade, and we discuss the results in the context of related developments.

Year: 2019

description: Braiding defects in topological stabiliser codes has been widely studied as a promising approach to fault-tolerant quantum computing. Here, we explore the potential and limitations of such schemes in codes of all spatial dimensions. We prove that a universal gate set for quantum computing cannot be realised by supplementing locality-preserving logical operators with defect braiding, even in more than two dimensions. However, notwithstanding this no-go theorem, we demonstrate that higher dimensional defect-braiding schemes have the potential to play an important role in realising fault-tolerant quantum computing. Specifically, we present an approach to implement the full Clifford group via braiding in any code possessing twist defects on which a fermion can condense. We explore three such examples in higher dimensional codes, specifically: in self-dual surface codes; the three dimensional Levin-Wen fermion mode; and the checkerboard model. Finally, we show how our no-go theorems can be circumvented to provide a universal scheme in three-dimensional surface codes without magic state distillation. Specifically, our scheme employs adaptive implementation of logical operators conditional on logical measurement outcomes to lift a combination of locality-preserving and braiding logical operators to universality.

description: Particles produced in high energy collisions that are charged under one of the fundamental forces will radiate proportionally to their charge, such as photon radiation from electrons in quantum electrodynamics. At sufficiently high energies, this radiation pattern is enhanced collinear to the initiating particle, resulting in a complex, many-body quantum system. Classical Markov Chain Monte Carlo simulation approaches work well to capture many of the salient features of the shower of radiation, but cannot capture all quantum effects. We show how quantum algorithms are well-suited for describing the quantum properties of final state radiation. In particular, we develop a polynomial time quantum final state shower that accurately models the effects of intermediate spin states similar to those present in high energy electroweak showers. The algorithm is explicitly demonstrated for a simplified quantum field theory on a quantum computer.

Measurement of the top-quark mass in $t\bar{t}+1$-jet events collected with the ATLAS detector in $pp$ collisions at $\sqrt{s}=8$ TeV
Creators: name: ATLAS Collaboration

Subjects: subject: High Energy Physics - Experiment (hep-ex)

description: A determination of the top-quark mass is presented using 20.2 $\text{fb}^{-1}$ of 8 TeV proton-proton collision data produced by the Large Hadron Collider and collected by the ATLAS experiment. The normalised differential cross section of top-quark pair production in association with an energetic jet is measured in the lepton+jets final state and unfolded to parton and particle levels. The unfolded distribution at parton level can be described using next-to-leading-order QCD predictions in terms of either the top-quark pole mass or the running mass as defined in the (modified) minimal subtraction scheme. A comparison between the experimental distribution and the theoretical prediction allows the top-quark mass to be extracted in the two schemes. The value obtained for the pole-mass scheme is: \[ m_t^{\text{pole}} = 171.1 \pm 0.4 (\text{stat}) \pm 0.9 (\text{syst}) \substack{+0.7\\ -0.3} (\text{theo}) \text{ GeV}. \] The extracted value in the running-mass scheme is: \[ m_t(m_t) = 162.9 \pm 0.5 (\text{stat}) \pm 1.0 (\text{syst}) \substack{+2.1\\ -1.2} (\text{theo}) \text{ GeV}. \] The results for the top-quark mass using the two schemes are consistent, when translated from one scheme to the other.

description: We study the cosmology and LHC phenomenology of a consistent strongly interacting dark sector coupled to Standard Model particles through a generic vector mediator. We lay out the requirements for the model to be cosmologically viable, identify annihilations into dark vector mesons as the dominant dark matter freeze-out process and discuss bounds from direct detection. At the LHC the model predicts dark showers, which can give rise to semi-visible jets or displaced vertices. Existing searches for di-jet resonances and for missing energy mostly probe the parameter regions where prompt decays are expected and constrain our model despite not being optimised for dark showers. We also estimate the sensitivity of dedicated analyses for semi-visible jets and emphasize the complementarity of different search strategies.

description: We consider a setting where a stream of qubits is processed sequentially. We derive fundamental limits on the rate at which classical information can be transmitted using qubits that decohere as they wait to be processed. Specifically, we model the sequential processing of qubits using a single server queue, and derive expressions for the classical capacity of such a quantum `queue-channel.' Focusing on two important noise models, namely the erasure channel and the depolarizing channel, we obtain explicit single-letter capacity formulas in terms of the stationary waiting time of qubits in the queue. Our capacity proof also implies that a `classical' coding/decoding strategy is optimal, i.e., an encoder which uses only orthogonal product states, and a decoder which measures in a fixed product basis, are sufficient to achieve the classical capacity of both queue-channels. Our proof technique for the converse theorem generalizes readily -- in particular, whenever the underlying quantum noise channel is additive, we can obtain a single-letter upper bound on the classical capacity of the corresponding quantum queue-channel. More broadly, our work begins to quantitatively address the impact of decoherence on the performance limits of quantum information processing systems.

Subjects: subject: Sociology

description: The study design called for a longitudinal evaluation of one hundred subjects enrolled in a vocational counseling program for recovering alcoholics. Due to CETA stipend cuts, and slowing of referrals, eighty subjects were studied. Subjects were administered two questionnaires, one at program entry, the second at a six month follow-up point. The study's primary purpose was to identify those factors associated with success. Success was defined as diminution or elimination of the problem drinking pattern and employment at follow-up. A number of hypotheses were tested. The study was carried out over the course of twenty-three months.

The mean age for subjects was 41. There were sixty-one men and nineteen women, 28% were members of a minority group. Subjects were typical of clinical treatment samples, more socially and psychologically impaired than a cross-section of the general drinking population. The majority were referred to the program by out-patient treatment facilities.

Seventy-seven percent of the subjects mailed in their follow-up questionnaire. At follow-up the rate of employment was 56%. Employment was associated with the following factors: Program completion, younger age, some college education or beyond, abstinence or controlled drinking, higher rates of religious participation. Women and minority members were as successful in securing jobs as white males.

The majority of the subjects were abstinent, with 13% problem drinking. Abstinence or controlled drinking was associated with the following factors: Employment, older age, minority group membership, no use of other drugs.

Comparing employed with unemployed subjects, we found the unemployed were more likely to be drinking, and were experiencing higher rates of depression.

Few subjects had strong family or friendship ties.

Counselors' predictions of subject performance reflected a favorable bias toward subjects with particular characteristics. Predictions had a high rate of accuracy, raising questions about the effect of counselor bias on subject performance. Overall, subjects rated the impact of the program high to moderately high.
Lattice computation of energy moments in canonical and Gaussian quantum statistics

description: We derive a lattice approximation for a class of equilibrium quantum statistics describing the behaviour of any combination and number of bosonic and fermionic particles with any sufficiently binding potential. We then develop an intuitive Monte Carlo algorithm which can be used for the computation of expectation values in canonical and Gaussian ensembles and give lattice observables which will converge to the energy moments in the continuum limit. The focus of the discussion is two-fold: in the rigorous treatment of the continuum limit and in the physical meaning of the lattice approximation. In particular, it is shown how the concepts and intuition of classical physics can be applied in this sort of computation of quantum effects. We illustrate the use of the Monte Carlo methods by computing canonical energy moments and the Gaussian density of states for charged particles in a quadratic potential.

Harnessing the Power of HPC From the Comfort of R
Creators: name: Scott, Eric
Publisher: name: Zenodo
Year: 2024

description: Many academics feel comfortable wrangling and analyzing data in R, but have little to noexperience working on the command line and may find job scheduling systems like SLURMintimidating. This can be a significant barrier for using high performance computing whichgenerally requires creating BASH scripts and submitting jobs via the command line. The{targets} R package provides many benefits to researchers, one of which is running steps of ananalysis automatically as job requests on an HPC all from the comfort of R.The {targets} package allows for workflow management of analysis pipelines in R wheredependencies among steps are automatically detected1. When a {targets} pipeline is modifiedand re-run, any steps (called “targets”) that do not need to be rerun are automatically skipped,saving compute time. By default, {targets} pipelines are launched in a “clean” R session, whichenforces reproducibility (a blessing to some and a curse to others). It is relatively trivial toparallelize a {targets} workflow so that independent targets are run on parallel workers eitherlocally as multiple R sessions, or using HPC or cloud computing resources2,3. Users can definea controller that runs their pipeline on the HPC using multiple workers running as separateSLURM jobs (or PBS, SGE, etc.). It is also possible to define multiple controllers with differentresources for different targets so that tasks with heavier computational needs are run with moreCPUs, for example. All of this happens from the comfort of R without users needing to manuallycreate multiple R scripts and/or multiple SLURM submission scripts for each task.RSEs and HPC professionals can help enable this powerful combination of technologies in afew ways. At University of Arizona, our group has created a template GitHub repository for a{targets} project that can run on the UA HPC either through the command line where targets arerun as SLURM requests or with Open OnDemand where targets are run on multiple Rsessions4. It includes code for a controller function that works with the UA HPC anddocumentation about how to modify the template and get it onto the HPC with git clone. Wehave previously run {targets} workshops that help researchers re-factor their analysis scripts into{targets} pipelines5. We hope to work with HPC professionals to increase awareness of {targets}as an option for R users to harness the power of cluster computing.

description: We review the basic ideas of the dynamical mean field theory (DMFT) and some of the insights into the electronic structure of strongly correlated electrons obtained by this method in the context of model Hamiltonians. We then discuss the perspectives for carrying out more realistic DMFT studies of strongly correlated electron systems and we compare it with existent methods, LDA and LDA+U. We stress the existence of new functionals for electronic structure calculations which allow us to treat situations where the single--particle description breaks down such as the vicinity of the Mott transition.

description: Transnational institutions increasingly commit multinational companies to human rights and social standards on a voluntary basis. Our paper investigates the security practices of multinational companies and whether these comply with the Voluntary Principles on Security and Human Rights. Analysing the case of mining companies in the Democratic Republic of Congo we evaluate the impact of the Principles on local security practices and critically analyse the effects of these practices. We argue that one needs to go beyond compliance studies, which focus on the implementation of formal programs (output) and rule-consistent behaviour (outcome), in order to evaluate corporate governance contributions. We therefore develop a conceptual framework that looks at companies’ local security practices, including non-compliant practices, and their effects on local security. Our approach leads to a more differentiated evaluation of the effects of voluntary standards and the potential for corporate governance contributions than much of the literature on business and governance does.
description: Multinationale Unternehmen werden zunehmend von transnationalen Institutionen auf freiwilliger Basis zu Menschenrechten und Sozialstandards verpflichtet. Unser Beitrag untersucht die Sicherheitspraktiken von Unternehmen und fragt, inwiefern sich diese an die Voluntary Principles on Security and Human Rights halten. Anhand von zwei multinationalen Bergbaufirmen in der Demokratischen Republik Kongo untersuchen wir die Wirkung dieser Standards auf die Sicherheitspraktiken der Firmen, nehmen darüber hinaus aber auch die Auswirkung der Firmenpraktiken auf die lokale Sicherheitslage in den Blick. Wir argumentieren dass man über die Compliance-Forschung, die auf die Implementierung formaler Programme und regelkonformes Verhalten fokussiert, hinaus gehen muss um freiwillige Standards sowie die Wirkung von Unternehmen auf Sicherheit in Räumen begrenzter Staatlichkeit zu evaluieren. Wir entwickeln dazu einen „bottom-up“ Ansatz der die gesamte Spanne lokaler Sicherheitspraktiken von Unternehmen sowie ihre – oft negativen – Effekte in den Blick nimmt. Dieser Ansatz erlaubt eine differenziertere Bewertung der Wirkung freiwilliger Standards als auch der Beiträge von Unternehmen zu lokaler Sicherheit.
