Year: 2013
Subjects: Roman provinces; modern states; nationalism; cultural models

description: L’articolo illustra l’interpretazione data in età moderna di alcune categorie del mondo romano. In particolare si sofferma sull’influenza della cultura nazionale del XIX e XX secolo sui concetti di “provincia” e di “impero”, entrambi letti in chiave territoriale. Tale visione è all’origine, anche a livello storiografico, di modelli estremamente distanti dalla realtà antica.

This article shows how modern culture interprets some categories of the Roman world. In particular, it analyzes the influences of 19th and 20th century national view on the concepts of “province” and “empire”, which are both conceived as territorial structures. Such a perspective originated many historiographical models which are very far away from ancient phenomena.

The federally sponsored housing market crash: race, finance, and heartbreak in the Pocono Mountains
Creators: name: Zyndorf, Benjamin
Publisher: name: No Publisher Supplied
Year: 2021

description: In this paper I argue that the 2008 housing market crash was the culmination of a decades-long legislative process enabled by the federal government. I analyze the effects of these policies on Monroe County, Pennsylvania, which became and continues to be the site of one the worst foreclosure crises nationally. Federal policies that promoted decentralization, deindustrialization, and deregulation created the conditions in Monroe County that allowed real estate developers, banks, and brokers to take advantage of an urban crisis that was only 1.5 hours away in New York City—without traffic. I describe the process through the story of real estate developer Gene Percudani. Enabled by the federal government, Percudani lured black and Hispanic residents from New York City who were looking for affordable single family homes, safe neighborhoods, and good schools. Not only did these migrants not escape the urban crisis but continued to be victims of it—far away from home.

description: The quantum anomalous Hall (QAH) effect is sometimes observed in twisted bilayer graphene (tBG) when it is nearly aligned with an encapsulating hexagonal boron nitride (hBN) layer. We propose that the appearance or absence of the QAH effect in individual devices could be related to commensurability between the graphene/graphene and graphene/hBN moiré patterns. We identify a series of points in the $(θ_{\rm GG},θ_{\rm GBN})$ twist-angle space at which the two moiré patterns are commensurate, allowing moiré band theory to be applied, and show that the band Chern numbers are in this case sensitive to a rigid in-plane hBN displacement. Given this property, we argue that the QAH effect is likely only when i) the $(θ_{\rm GG},θ_{\rm GBN})$ twist-angle-pair is close enough to a commensurate point that the two moiré patterns yield a supermoiré pattern with a sufficiently long length scale, and ii) the supermoiré has a percolating topologically non-trivial QAH phase. For twist angles far from commensurability, the hBN layer acts as a source of disorder that can destroy the QAH effect. Our proposal can explain a number of current experimental observations. Further experimental studies that can test this proposal more directly are suggested.
Il decreto ateniese per i Faseliti (IG I3 10) e le multe di 10.000 dracme nel V sec.

description: Nei decreti dell’Assemblea ateniese del V sec. a.C. è frequente la previsione di multe a carico di magistrati o di cittadini che ostacolino l’applicazione dei provvedimenti adottati. Sono noti dieci casi in cui i decreti minacciano gli inadempienti con l’enorme somma di 10.000 dracme: secondo le datazioni oggi più accreditate uno di questi decreti è posteriore al 434, otto appartengono certamente al periodo della Guerra del Peloponneso, in particolare agli anni Venti (sei casi). Questo lavoro prende approfonditamente in esame IG I3 10 – il Decreto per i Faseliti oggetto di proposte di datazione oscillanti tra il 466 e l’inizio del IV sec. – sostenendo che proprio l’ammontare della multa costituisca un importante elemento aggiuntivo in appoggio ad una datazione del documento intorno al 425, abbondantemente corroborata da altri riscontri.

In the 5th century BC, the Athenian Assembly frequently issued decrees which threatened to impose heavy fines on those magistrates or commoners who obstructed the enforcement of the laws approved by the Assembly itself. Today we know ten inscriptions reporting as many decrees, in which the fines were fixed at 10.000 drachmai, a stunningly high amount of money. According to the most trustworthy hypotheses concerning the date of these decrees, one of them was approved in (or after) 434 BC, while eight relate undoubtedly to the period of the Peloponnesian War, especially to the ’20s (six cases out of eight). Through a thorough analysis of IG I3 10 – the “Phaselis Decree”, which various scholars have dated differently, ranging from 466 to the beginning of the 4th century BC – this paper argues that, besides other historical proof, the amount of the fine is an important piece of evidence which strongly supports the suggestion for the dating of the decree around 425 BC.

description: We have studied photoluminescence (PL) and resonant Raman scatterings of single-walled carbon nanotubes (SWNTs) consisting of carbon-13 (SW13CNTs) synthesized from a small amount of isotopically modified ethanol. There was almost no change in the Raman spectra shape for SW13CNTs except for a downshift of the Raman shift frequency by the square-root of the mass ratio 12/13. By comparing photoluminescence excitation (PLE) spectra of SW13CNTs and normal SWNTs, the excitonic phonon sideband due to strong exciton-phonon interaction was clearly identified with the expected isotope shift.

description: In questo articolo intendo mostrare come sia possibile impiegare categorie nietzschiane per chiarire e approfondire alcuni motivi centrali nel pensiero del primo Sartre, e in particolare per mettere in luce il volto nichilistico del concetto di libertà presente ne L’essere e il nulla. Innanzitutto, spiego come per Sartre l’uomo non sia altro che pura e assoluta libertà. Intrecciando questo tema con il concetto nietzschiano di nichilismo, dimostro allora come l’esistenzialismo si sveli un pensiero profondamente nichilistico, poiché non offre un fondamento trascendente ai valori di cui la libertà dell’uomo è in realtà unico luogo d’origine. Su questa base, mostro come i concetti di volontà di potenza e di oltre-uomo ci aiutino ad approfondire la concezione sartriana dell’uomo come pura e assoluta libertà. In conclusione propongo una riflessione attorno alla domanda: il nichilismo

description: The integer quantum Hall transition (IQHT) is one of the most mysterious members of the family of Anderson transitions. Since the 1980s, the scaling behavior near the IQHT has been vigorously studied in experiments and numerical simulations. Despite all efforts, it is notoriously difficult to pin down the precise values of critical exponents, which seem to vary with model details and thus challenge the principle of universality. Recently, M. Zirnbauer\citep{Zirnbauer2019} [Nucl. Phys. B \textbf{941}, 458 (2019)] has conjectured a conformal field theory for the transition, in which linear terms in the beta-functions vanish, leading to a very slow flow in the fixed point's vicinity which we term marginal scaling. In this work, we provide numerical evidence for such a scenario by using extensive simulations of various network models of the IQHT at unprecedented length scales. At criticality, we show that the finite-size scaling of the disorder averaged longitudinal Landauer conductance is consistent with its recently predicted fixed-point value and a third-order expansion of RG beta functions. In the future, our numerical findings can be checked with analytical results from the conformal field theory. Away from criticality we describe a mechanism that could account for the emergence of an \emph{effective} critical exponents $ν_\mathrm{eff}$, which is necessarily dependent on the parameters of the model. We further support this idea by numerical determination of $ν_\mathrm{eff}$ in suitably chosen models.

description: Exciton spin relaxation is investigated in single epitaxially grown semiconductor quantum dots in order to test the expected spin relaxation quenching in this system. We study the polarization anisotropy of the photoluminescence signal emitted by isolated quantum dots under steady-state or pulsed non-resonant excitation. We find that the longitudinal exciton spin relaxation time is strikingly short ($\leq$100 ps) even at low temperature. This result breaks down the picture of a frozen exciton spin in quantum dots.

description: Si presentano in questo saggio otto lettere inviate da Theodor Mommsen a Carlo e Vincenzo Promis. Le lettere si inseriscono nel fitto carteggio intercorso tra Mommsen e alcuni studiosi italiani per la costruzione del Corpus Inscriptionum Latinarum. Protagoniste delle lettere sono le richieste concernenti alcune iscrizioni latine che Pirro Ligorio ha raccolto all'interno dei manoscritti oggi conservati presso l'Archivio di Stato di Torino. L'analisi di queste lettere ha consentito di osservare più da vicino il pensiero di Mommsen nei confronti dell'antiquario napoletano e di riscontrare in corso d'opera i criteri adottati per l’edizione delle falsae ligorianae.

In this paper are published eight letters sent from Theodor Mommsen to Carlo and Vincenzo Promis. These letters belong to the rich correspondence entertained between Mommsen and some Italian scholars aimed at the Corpus Inscriptionum Latinarum construction. A leading role is played by requests about Pirro Ligorio Latin inscriptions collected in the manuscripts now kept in the Turin National Archives. Analysing these letters permits us directly to know Mommsen's opinion about the Neapolitan antiquarian, and especially to closer observe some parameters used for the falsae ligorianae edition.

description: Presentation Abstract

eoAPI is a new, open-source, installable combination of data catalog and associated services for earth observation and related data with a cloud-computing infrastructure first approach. eoAPI combines STAC data ingestion, data hosting (pgSTAC), and querying services (stac-fastapi) with, raster (Titiler) and vector services (TiPg). eoAPI is built for reuse and has been used to power applications such as NASA’s VEDA Open Science Platform, the multi-agency Greenhouse Gas Center, MS Planetary Computer, and AWS ASDI’s data catalog and applications for International Federation of the Red Cross and MercyCorps.

The SpatioTemporal Asset Catalog (STAC) specification provides a common language for earth observation (EO) data. STAC is used to power data discovery, visualization, train ML models, and perform Earth data science. By putting data into STAC, we can dynamically select parts of large catalogs of data, combine them together, and derive insights in multiple ways. .

A wide range of open tools has made working and publishing with EO data at scale easier, however, the flexibility of the STAC specification makes it difficult for an organization to select which projects to choose, given their varying degrees of interoperability. eoAPI takes the work out of constructing a cloud-native EO infrastructure through an opinionated blueprint that will work well for most EO and geospatial infrastructure needs. eoAPI lowers the barrier to those who are both STAC-curious and STAC-serious.

The presentation will cover eoAPI services, infrastructure as code, a demonstration of how the API is used and an explanation of eoAPI is reused across applications, as listed in the first paragraph.

A developer with limited DevOps experience could deploy eoAPI. We believe we can do even better to make STAC catalogs and services on-demand and will share progress towards a 1-click deployment with attendees.
Robotic Reverberation Mapping of the Southern Seyfert NGC 3783

description: We present spectroscopic and photometric monitoring of NGC 3783 conducted throughout the first half of 2020. Time delays between the continuum variations and the response of the broad optical emission lines were clearly detected, and we report reverberation measurements for H$β$, HeII $λ4686$, H$γ$, and H$δ$. From the time delay in the broad H$β$ emission line and the line width in the variable portion of the spectrum, we derive a black hole mass of $M_{\rm BH} = 2.34^{+0.43}_{-0.43} \times 10^7$ M$_{\odot}$. This is slightly smaller than, but consistent with, previous determinations. However, our significantly improved time sampling ($T_{\rm med}=1.7$ days compared to $T_{\rm med}=4.0$ days) has reduced the uncertainties on both the time delay and the derived mass by $\sim 50$%. We also detect clear velocity-resolved time delays across the broad H$β$ profile, with shorter lags in the line wings and a longer lag in the line core. Future modeling of the full velocity-resolved time delay response will further improve the reverberation-based mass for NGC 3783, adding it to the small but growing sample of AGNs for which we have direct, primary black hole mass measurements. Upcoming MUSE observations at VLT will also allow NGC 3783 to join the smaller sample of black holes where reverberation masses and masses from stellar dynamical modeling may be directly compared.

description: The best performance of a Mach-Zehnder interferometer is achieved with the input state |N_T/2 + 1>|N_T/2-1 > + |N_T/2 - 1>|N_T/2+1>, being N_T the total number of atoms/photons. This gives: i) a phase-shift error confidence C_{68%}=2.67/N_T with ii) a single interferometric measurement. Different input quantum states can achieve the Heisenberg scaling ~ 1/N_T but with higher prefactors and at the price of a statistical analysis of two or more independent measurements.

description: We numerically investigate the dynamical properties of $κ$-type molecular conductors in their antiferromagnetic Mott insulating state. By treating the extended Hubbard model on the two-dimensional $κ$-type lattice within the Lanzcos exact diagonalization method, we calculate the one-particle spectral function $A(\boldsymbol{k}, ω)$ and the optical absorption spectra taking advantage of twisted boundary conditions. We find spin splitting in $A(\boldsymbol{k}, ω)$ predicted by a previous Hartree-Fock study [M. Naka et al., Nat. Commun. 10, 4305 (2019)]; namely, their up- and down-spin components become different in the general $\boldsymbol{k}$-points of the Brillouin zone, even without the spin-orbit coupling. Furthermore, we demonstrate the variation in the optical properties near the Mott gap by the presence or absence of the antiferromagnetic order, tuned by a small staggered magnetic field.

description: In this work, we explore wormhole geometries in a recently proposed modified gravity theory arising from a non-conservative gravitational theory, tentatively denoted action-dependent Lagrangian theories. The generalized gravitational field equation essentially depends on a background four-vector $λ^μ$, that plays the role of a coupling parameter associated with the dependence of the gravitational Lagrangian upon the action, and may generically depend on the spacetime coordinates. Considering wormhole configurations, by using "Buchdahl coordinates", we find that the four-vector is given by $λ_μ=\left(0,0,λ_θ,0\right)$, and that the spacetime geometry is severely restricted by the condition $g_{tt}g_{uu}=-1$, where $u$ is the radial coordinate. We find a plethora of specific asymptotically flat, symmetric and asymmetric, solutions with power law choices for the function $λ$, by generalizing the Ellis-Bronnikov solutions and the recently proposed black bounce geometries, amongst others. We show that these compact objects possess a far richer geometrical structure than their general relativistic counterparts.

description: In questo articolo si ricostruisce il dibattito teorico sull’impegno dell’esistenzialismo tra Jean-Paul Sartre e Maurice Blanchot dal dopoguerra fino agli anni Ottanta. L’originalità del testo riguarda la composizione, in uno stesso orizzonte critico, delle due diverse visioni filosofiche. Per mostrare che la responsabilità degli scrittori è nel confronto e nel dialogo infratestuale. Tale problema è argomentato attraverso i riferimenti principali da Hegel, Kierkegaard, Jean Wahl a Georges Bataille e René Char come una questione sempre aperta, sempre presente nella cultura contemporanea e odierna.

description: Achieving consistency in hog quality has been one of the greatest challenges in the US pork industry. Packers, processors and retailers all ranked lack of uniformity in live hogs, carcasses, and retail cuts with regard to size and backfat as the most important quality issue facing the industry in the mid 1990s (NPPC, Pork Quality Audit, 1994), and quality consistency continues to be a leading industry concern (Martinez and Zering, 2004). The past 15 years have also witnessed dramatic changes in the organization of the US hog industry. In 1993, over 82% of hogs were sold through spot markets while 11% were sold under marketing contracts. By 2005, only 11% of hogs were sold through spot markets, with 67% sold under marketing contracts and over 20% owned by packers through formal integration or production contracts. This change in industry structure has not gone unnoticed by agricultural economists. A large body of literature examines the relations between hog quality and newly developed organization modes, particularly production contracting and vertical integration. A variety of theoretical frameworks and empirical approaches have been employed, whether using surveys (Kliebenstein and Lawrence, 1995), simulation techniques (Poray, 2002), contract document analysis (Martinez and Zering, 2004), and quality outcome analysis (Muth, et al., 2007). However, research focusing on production contracts and formal vertical integration fails to address the dominant institutional form, namely marketing contracts. Likewise, research focusing on market-based incentive mechanisms fails to provide a consistent explanation for the use and design of long-term hog marketing contracts. We propose a theoretical explanation for the use of long-term marketing contracts in the presence of buyer-specific quality attributes in an otherwise commoditized industry. This theoretical framework draws from and builds upon existing theories of contracting and organizational economics. In particular, the paper develops an analytical model that accounts for the use and structure of long-term marketing contracts to increase intertemporal quality consistency in hog procurement. The paper links the packer’s decision to move from spot-market transactions to long-term marketing contracts to the packer’s downstream product differentiation strategy. We provide empirical evidence to support the model and its explanatory power relative to existing theories.

We review integrals of the systems invariant under the corresponding Weyl group and as their limits we construct enough integrals of the non-invariant systems, which include systems whose complete integrability will be first established in this paper. We also present a conjecture claiming that the quantum systems with enough integrals given in this note coincide with the systems that have the integrals with constant principal symbols corresponding to the homogeneous generators of the $B_n$-invariants. We review conditions supporting the conjecture and give a new condition assuring it.

description: We discuss exploration for isotropic gravitational wave backgrounds around 1 mHz by correlation analysis, targeting both parity odd and even polarization modes. Even though the space interferometer LISA alone cannot probe the two modes due to cancellations, the outlook is being changed drastically by the strong development of other space detectors such as Taiji. In fact, a heliocentric interferometer network holds a preferable geometrical symmetry {illuminated by a virtual sphere off-center from the Sun}. By utilizing an internal symmetry of data streams, we can optimally decompose the odd and even parity modes at correlation analysis. By simultaneously using LISA and Taiji for 10 years, our sensitivity to the two modes could reach $\sim 10^{-12}$ in terms of the normalized energy density.

description: To meet the high performance demands of modern robot applications, design variables such as materials, geometry, actuators and sensors must be chosen for optimum performance. This thesis presents a new way of choosing design variables to tune the capabilities of a robot to the needs of an application. The associated proposals are demonstrated through the design of a haptic interface. It is argued that isotropy over a given workspace is a good measure of design quality for many high performance applications. A new measure of isotropy, the Global Isotropy Index or GII, is presented which is computed from the singular values of a design matrix. To ensure that the singular values are meaningful, a technique is presented which normalizes and scales the design matrix. The technique removes all physical units from the design matrix and scales it to accommodate an application-dependent performance specification and non-homogeneous actuator capabilities. An algorithm has also been developed that solves for the design parameters that result in the optimum GII. It is so efficient that it can be used to compare the relative isotropics of different robot configurations. Performance specifications for a haptic interface are taken from the literature and are augmented by two biomechanical studies. The values obtained are used by the proposed design procedure to select the best of three robots to be used as a haptic pen. The preferred candidate is a novel hybrid design that uses two 3- DOF pantographs to position the ends of a pen shaped end-effector. A prototype with passive roll about the pen axis is built and controlled to simulate three virtual environments including a virtual pencil, a virtual scalpel and a virtual excavator. Its performance characteristics are measured and are used to draw conclusions about the effectiveness of the design procedure. Finally, a further performance improvement is sought via redundant actuation. It is shown that the motion range and force capabilities of a coarse-stage robot can be combined with the precision and high-acceleration of a fine-stage robot by connecting them in series and joining their end-effectors by a flexible coupling. A coarse-fine system such as this is expected to narrow the gap between achievable and ideal haptic interface performance.

description: We report on direct feedback cooling of single nanoparticles in an optical lattice to near their motional ground state. We find that the laser phase noise triggers severe heating of nanoparticles' motion along the optical lattice. When the laser phase noise is decreased by orders of magnitude, the heating rate is reduced and accordingly the occupation number is lowered to about three. We establish a model directly connecting the heating rate and the measured laser phase noise and elucidates that the occupation number under the lowest laser phase noise in our system is limited only by photon recoil heating. Our results show that the reduction of the laser phase noise near the oscillation frequency of nanoparticles is crucial for bringing them near the ground state and pave the way to sensitive accelerometers and quantum mechanical experiments with ultracold nanoparticles in an optical lattice.

description: Recent advances in technology have provided massive amounts of complex high-dimensional and multimodal data for computer vision and machine learning applications. This thesis uses sparse and low-rank representation-based techniques to introduce several approaches for leveraging the complementary information from multimodal and high-dimensional data in clustering and recognition tasks. We start with a focus on subspace clustering algorithms. We extend the popular sparse and low-rank based subspace clustering methods to multimodal subspace clustering algorithms that can integrate multiple high-dimensional modalities and represent them in low-dimensional joint subspaces. We then use convolutional neural networks (CNNs) to improve our proposed multimodal subspace clustering methods and develop deep multimodal subspace clustering networks. Furthermore, we design a framework for incorporating data augmentation techniques in subspace clustering networks. In the second part of the thesis, we focus on developing multimodal classification approaches. We start with introducing deep sparse representation-based classification (DSRC) and extending it to its multimodal version. Then, we propose novel approaches for two real-world applications with high-dimensional and multimodal data. In particular, first, we introduce a method to leverage the knowledge of multiple video streams in dynamic hand gesture recognition tasks and embed the knowledge in every single unimodal network. As a result, we improve the accuracy of unimodal networks at the test time while they remain to perform in real-time. Our second applied approach is a fusion method for combining the information in social media posts' texts and images. Both texts and images are considered high-dimensional data, and in the case of social media posts, they can sometimes be uninformative or even misleading. We presented a method that is able to filter uninformative parts of text-image pairs and leverage their complementary information to detect crisis events in social media posts. Finally, we discuss some possible future research directions.

description: We study even parity metric and matter perturbations of all angular modes in self-similar Vaidya space-time. We focus on the case where the background contains a naked singularity. Initial conditions are imposed describing a finite perturbation emerging from the portion of flat space-time preceding the matter-filled region of space-time. The most general perturbation satisfying the initial conditions is allowed impinge upon the Cauchy horizon (CH), whereat the perturbation remains finite: there is no ``blue-sheet'' instability. However when the perturbation evolves through the CH and onto the second future similarity horizon of the naked singularity, divergence necessarily occurs: this surface is found to be unstable. The analysis is based on the study of individual modes following a Mellin transform of the perturbation. We present an argument that the full perturbation remains finite after resummation of the (possibly infinite number of) modes.

description: We present high signal precision optical reflectance spectra of 2005 FY9 taken with the Red Channel Spectrograph and the 6.5-m MMT telescope on 2006 March 4 UT (5000 - 9500 A; 6.33 A pixel-1) and 2007 February 12 UT (6600 - 8500 A; 1.93 A pixel-1). From cross correlation experiments between the 2006 March 4 spectrum and a pure CH4-ice Hapke model, we find the CH4-ice bands in the MMT spectrum are blueshifted by 3 +/- 4 A relative to bands in the pure CH4-ice Hapke spectrum. The higher resolution MMT spectrum of 2007 February 12 UT enabled us to measure shifts of individual CH4-ice bands. We find the 7296 A, 7862 A, and 7993 A CH4-ice bands are blueshifted by 4 +/- 2 A, 4 +/- 4 A, and 6 +/- 5 A. From four measurements we report here and one of our previously published measurements, we find the CH4-ice bands are shifted by 4 +/- 1 A. This small shift is important because it suggest the presence of another ice component on the surface of 2005 FY9. Laboratory experiments show that CH4-ice bands in spectra of CH4 mixed with other ices are blueshifted relative to bands in spectra of pure CH4-ice. A likely candidate for the other component is N2-ice because its weak 2.15 micron band and blueshifted CH4 bands are seen in spectra of Triton and Pluto. Assuming the shift is due to the presence of N2, spectra taken on two consecutive nights show no difference in CH4/N2. In addition, we find no measureable difference in CH4/N2 at different depths into the surface of 2005 FY9.

description: Mid-infrared (23-35 micron) emission from the deeply embedded "Class 0" protostar IRAS16293-2422 is detected with the Spitzer Space Telescope infrared spectrograph. A detailed radiative transfer model reproducing the full spectral energy distribution (SED) from 23 micron to 1.3 mm requires a large inner cavity of radius 600 AU in the envelope to avoid quenching the emission from the central sources. This is consistent with a previous suggestion based on high angular resolution millimeter interferometric data. An alternative interpretation using a 2D model of the envelope with an outflow cavity can reproduce the SED but not the interferometer visibilities. The cavity size is comparable to the centrifugal radius of the envelope and therefore appears to be a natural consequence of the rotation of the protostellar core, which has also caused the fragmentation leading to the central protostellar binary. With a large cavity such as required by the data, the average temperature at a given radius does not increase above 60-80 K and although hot spots with higher temperatures may be present close to each protostar, these constitute a small fraction of the material in the inner envelope. The proposed cavity will also have consequences for the interpretation of molecular line data, especially of complex species probing high temperatures in the inner regions of the envelope.

description: Die Beratung und psychotherapeutische Behandlung lesbischer, schwuler und bisexueller Klient_innen basierte in Deutschland lange auf pathologisierenden und abwertenden Konzeptionen homo- und bisexueller Lebensweisen. Nach der Entpathologisierung in den diagnostischen Manualen ICD und DSM entwickelte sich eine Diskrepanz zwischen einer zunehmenden Fülle von affirmativen und die Diversität dieser Bevölkerungsgruppe herausarbeitenden Forschungsarbeiten einerseits und der unzureichenden Integration des Fachwissens in die psychotherapeutische und beratende Praxis andererseits. Unterdessen wird die Bedeutung eines Verständnisses der Kontextbedingungen, unter denen lesbische, schwule und bisexuelle Klient_innen leben, für eine fachgerechte Gestaltung von Beratung und Psychotherapie zunehmend anerkannt. Mit den hier vorgestellten Empfehlungen des VLSP e.V. für die psychotherapeutische und beratende Arbeit mit lesbischen, schwulen und bisexuellen Klient_innen möchten wir für Fachkolleg_innen eine transparente und evidenzbasierte Handlungsgrundlage für die psychosoziale Arbeit mit lesbischen, schwulen und bisexuellen Menschen anbieten. Auch für die Klient_innen selbst möchten wir durch die Empfehlungen Wissen für die Nutzung psychotherapeutischer und beratender Angebote bereitstellen. Unser Ziel ist es, damit eine fachlich fundierte, kontextsensible, hilfreiche, Schäden vermeidende Gesundheitsversorgung von Lesben, Schwulen und Bisexuellen zu fördern.

description: There exist natural generalizations of the real moduli space of Riemann spheres based on manipulations of Coxeter complexes. These novel spaces inherit a tiling by the graph-associahedra convex polytopes. We obtain explicit configuration space models for the classical infinite families of finite and affine Weyl groups using particles on lines and circles. A Fulton-MacPherson compactification of these spaces is described and this is used to define the Coxeter operad. A complete classification of the building sets of these complexes is also given, along with a computation of their Euler characteristics.

description: We consider evolution of a Fermi gas in the presence of a time-dependent BCS interaction. The pairing amplitude in the emergent BCS state is found to be an oscillatory function of time with predictable characteristics. The interplay of linear instability of the unpaired state and nonlinear interactions selects periodic soliton trains of a specific form, described by the Jacobi elliptic function dn. While the parameters of the soliton train, such as the period, amplitude, and time lag, fluctuate among different realizations, the elliptic function form remains robust. The parameter variation is accounted for by the fluctuations of particle distribution in the initial unpaired state.
