description: We present electron-tunneling spectroscopy of slightly overdoped Bi2212 single crystals with Tc = 87 - 90 K in a temperature range between 14 K and 290 K using a break-junction technique. The pseudogap which has been detected above Tc appears at T* = 280 K. The analysis of the spectra shows that there is a contribution to the pseudogap above Tc, which disappears approximately at 110 - 115 K. We associate this contribution with the presence of incoherent Cooper pairs.

Impact of cell intrinsic properties on transplantation in rodent models of Parkinson's disease

description: Proof of concept studies for cell replacement therapy (CRT) for Parkinson’s disease (PD) were performed using fetal tissue. Post-mortem results indicated surviving grafts more than 2 decades post-transplant. However, they also showed the presence of a-synuclein (a-syn) pathology within some of the grafted cells, which was not predicted from preclinical studies in the 6-OHDA model. This model is most commonly used for preclinical assessment of CRT for PD but fails to recapitulate many features of the human condition, including progressive DA degeneration, a-syn accumulation, and inflammation. Since the discovery of cell reprogramming, e.g. iPSCs, reprogrammed cells have been proposed as an alternative source for CRT. However, further research investigating patient-derived reprogrammed cells, including their potential susceptibility to disease processes, is needed to assess their suitability moving forward to the clinic. In this study we will investigate if cell intrinsic properties affect graft survival, integrity, and functional maturation. We derived DA progenitors from a human ESC line or an a-syn triplication patient iPSC line and transplanted them into the 6-OHDA model or accelerated a-syn model. In the 6-OHDA model, we found no difference in graft volume or TH cell density, however, there was a significant difference in graft innervation. In the accelerated a-syn model, we observed behavioural recovery 24 weeks post-transplant in both groups and further histological analysis is ongoing, specifically investigating the presence of a-syn pathology. The comparison between healthy and patient-derived cells will pave the way for future research assessing reprogrammed cells’ potential for brain repair and disease modelling.
High field transport in strained Si/GeSi double heterostructure: a Fokker-Planck approach

description: We report calculations of high electric field transport for the case of a strained Si/GeSi double heterostructure (DHS) considering transport along the Si channel and by applying the analytical Fokker-Planck approach (FPA), where the process is modeled as drift-diffusion in energy space. We limit ourselves to electronic transport in the conduction band of the strained Si, where an energy shift between the otherwise degenerate six energy valleys characterizes the band alingment in the DHS. Intervalley phonon scatterings are considered while intravalley acoustic phonon scattering is ignored, leading to results valid for high enough temperatures. Our results are compared to previous theoretical works where Monte Carlo simulations were applied. A reasonable agreement between the two approaches is obtained in the high electric field regime.

description: We report on luminescent centers contained in a few-layer-thick hexagonal boron nitride (h-BN) film grown on Ni by molecular beam epitaxy. After transfer to a SiO$_2$/Si substrate, sharp lines are observed in photo- and cathodoluminescence spectra in both the ultraviolet and the visible range. Spatially resolved measurements reveal that the luminescent centers responsible for these lines are localized within microscopic multi-layer islands that form at the nucleation centers of the h-BN film. The comparison of their energy, polarization and phonon replica emission with previous theoretical predictions suggest that the N$_\mathrm{B}$V$_\mathrm{N}$ anti-site could be one of the light emitters present in our sample. Moreover, we have also observed evidences of other kinds of centers that could be associated to defects containing carbon or oxygen. The characterized luminescent defects could have potential applications as quantum light sources.

description: The spin gap of a one-dimensional repulsive Hubbard model is numerically calculated with the density matrix renormalization group, with a special emphasis on the effect of a next-nearest neighbor hopping (t') and the nearest-neighbor ferromagnetic exchange (J) interaction. At half-filling, a significant spin gap opens if |t'| \simeq |t| and J=0, in agreement with the weak coupling theory, while the gap is strongly suppressed by the introduction of J. On the other hand, the quarter-filled system has very small spin gaps regardless of the values of t' and J. Implications for the CuO_2 chain in Sr_{14}Cu_{24}O_{41} and related materials are discussed.

A Question-Entailment Approach to Question Answering

description: One of the challenges in large-scale information retrieval (IR) is to develop fine-grained and domain-specific methods to answer natural language questions. Despite the availability of numerous sources and datasets for answer retrieval, Question Answering (QA) remains a challenging problem due to the difficulty of the question understanding and answer extraction tasks. One of the promising tracks investigated in QA is to map new questions to formerly answered questions that are `similar'. In this paper, we propose a novel QA approach based on Recognizing Question Entailment (RQE) and we describe the QA system and resources that we built and evaluated on real medical questions. First, we compare machine learning and deep learning methods for RQE using different kinds of datasets, including textual inference, question similarity and entailment in both the open and clinical domains. Second, we combine IR models with the best RQE method to select entailed questions and rank the retrieved answers. To study the end-to-end QA approach, we built the MedQuAD collection of 47,457 question-answer pairs from trusted medical sources, that we introduce and share in the scope of this paper. Following the evaluation process used in TREC 2017 LiveQA, we find that our approach exceeds the best results of the medical task with a 29.8% increase over the best official score. The evaluation results also support the relevance of question entailment for QA and highlight the effectiveness of combining IR and RQE for future QA efforts. Our findings also show that relying on a restricted set of reliable answer sources can bring a substantial improvement in medical QA.
title: The Role of Corporate Saving over the Business Cycle: Shock Absorber or Amplifier?
Creators: name: Gao, Xiaodan
name: Xu, Shaofeng
Publisher: name: Bank of Canada
Year: 2018

description: We document countercyclical corporate saving behavior with the degree of countercyclicality varying nonmonotonically with firm size. We then develop a dynamic stochastic general equilibrium model with heterogeneous firms to explain the pattern and study its implications for business cycles. In the presence of financial frictions and fixed operating costs, a persistent negative productivity shock signals low future income and prompts firms to hold more cash in order to preserve financial flexibility and maintain normal operations. This countercyclicality exhibits a hump-shaped relation to firm size. Compared with medium-sized firms, small firms have a higher marginal product of capital and thus better investment opportunities, which compete for resources with cash, while large firms have more pledgeable assets and demand less cash. We find that, on average, firms accumulate cash by cutting investment and employment in recessions, which reduces aggregate output and increases economic fluctuations. Corporate saving, therefore, amplifies aggregate shocks.
description: Dans la présente étude, nous montrons tout d’abord que les entreprises ont un comportement d’épargne contracyclique, qui varie de façon non monotone avec leur taille. Nous élaborons ensuite un modèle d’équilibre général dynamique et stochastique intégrant des entreprises hétérogènes pour expliquer cette tendance et en étudier l’incidence sur les cycles économiques. En présence de frictions financières et de coûts fixes d’exploitation, un choc de productivité négatif persistant laisse augurer de faibles revenus futurs et incite les entreprises à détenir plus de liquidités pour préserver leur souplesse sur le plan financier et continuer à fonctionner normalement. La relation entre ce comportement contracyclique et la taille des entreprises se traduit par une courbe en bosse. Comparativement aux moyennes entreprises, les petites entreprises bénéficient d’une productivité marginale du capital plus élevée, et donc de meilleures possibilités d’investissement, rendant l’accumulation de liquidités moins attrayante. Quant aux grandes entreprises, elles ont davantage d’actifs à donner en garantie et nécessitent donc moins de liquidités. Nous constatons qu’en moyenne, les entreprises accroissent leurs liquidités en réduisant leurs investissements et leur personnel en période de récession. La production globale s’en voit ainsi réduite, et les fluctuations économiques augmentent. C’est donc dire que l’épargne des entreprises amplifie les chocs globaux.

description: In this chapter tools and techniques from the mathematical theory of formal concept analysis are applied to hypertext systems in general, and the World Wide Web in particular. Various processes for the conceptual structuring of hypertext are discussed: summarization, conceptual scaling, and the creation of conceptual links. Well-known interchange formats for summarizing networked information resources as resource meta-information are reviewed, and two new interchange formats originating from formal concept analysis are advocated. Also reviewed is conceptual scaling, which provides a principled approach to the faceted analysis techniques in library science classification. The important notion of conceptual linkage is introduced as a generalization of a hyperlink. The automatic hyperization of the content of legacy data is described, and the composite conceptual structuring with hypertext linkage is defined. For the conceptual empowerment of the Web user, a new technique called conceptual browsing is advocated. Conceptual browsing, which browses over conceptual links, is dual mode (extensional versus intensional) and dual scope (global versus local).

description: Time dependent phenomena associated to charge transport along a quantum dot in the charge quantization regime is studied. Superimposed to the Coulomb blockade behaviour the current has novel non-linear properties. Together with static multistabilities in the negative resistance region of the I-V characteristic curve, strong correlations at the dot give rise to self-sustained current and charge oscillations. Their properties depend upon the parameters of the quantum dot and the external applied voltages.

Volume changes in binary alloy ordering, a binary classical density functional theory approach

Year: 1998
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: The chemical ordering transition in a binary alloy is examined using classical density functional theory for a binary mixture. The ordered lattice is assumed to be obtained from the disordered lattice by a volume change only, as in L1_2 ordering from an face centered cubic chemically disordered crystal. Using the simplest possible approach, second order truncation of the expansion, non-overlapping Gaussian distributions at the sites, and expansion of the correlation functions about the sites, a very tractable expansion is obtained. Under these assumptions the expansion consists of the same terms as the lattice gas formalism where the lattice is implicitly taken as fixed, plus additional interaction terms, and an additional entropy term. This additional entropy term represents a lowest order approximation to the vibrational entropy change.

description: We introduce the notion of the Color Glass Condensate (CGC) density matrix $\hatρ$. This generalizes the concept of probability density for the distribution of the color charges in the hadronic wave function and is consistent with understanding the CGC as an effective theory after integration of part of the hadronic degrees of freedom. We derive the evolution equations for the density matrix and show that the JIMWLK evolution equation arises here as the evolution of diagonal matrix elements of $\hatρ$ in the color charge density basis. We analyze the behavior of this density matrix under high energy evolution and show that its purity decreases with energy. We show that the evolution equation for the density matrix has the celebrated Kossakowsky-Lindblad form describing the non-unitary evolution of the density matrix of an open system. Additionally, we consider the dilute limit and demonstrate that, at large rapidity, the entanglement entropy of the density matrix grows linearly with rapidity according to $d S_e / d y = γ$, where $γ$ is the leading BFKL eigenvalue. We also discuss the evolution of $\hatρ$ in the saturated regime and relate it to the Levin-Tuchin law and find that the entropy again grows linearly with rapidity, but at a slower rate. By analyzing the dense and dilute regimes of the full density matrix we are able to establish a duality between the regimes. Finally we introduce the Wigner functional derived from this density matrix and discuss how it can be used to determine the distribution of color currents, which may be instrumental in understanding dynamical features of QCD at high energy.

description: For a frequency-tunable two-qubit system, a controlled-Z (CZ) gate can be realized by adiabatically driving the qubit system through an avoided level crossing between an auxiliary state and computational levels. Here, we theoretically propose a fast CZ gate using a shortcut-to-adiabaticity (STA). Experimentally, the STA CZ gate is implemented with a 52 ns control pulse for two coupled superconducting Xmon qubits. Measured fidelity of the STA CZ gate is higher than 96.0%, in both quantum process tomography and randomized benchmarking. The protocol allows a flexible design of the evolution time and control waveform. We suggest that this `fast adiabatic' CZ gate can be directly applied to other multi-qubit quantum systems.

description: We study the scattering of long strings in c = 1 string theory, both in the worldsheet description and in the non-singlet sector of the dual matrix quantum mechanics. From the worldsheet perspective, the scattering amplitudes of long strings are obtained from a decoupling limit of open strings amplitudes on FZZT branes, which we compute by integrating Virasoro conformal blocks along with structure constants of boundary Liouville theory. In particular, we study the tree level amplitudes of (1) a long string decaying by emitting a closed string, and (2) the scattering of a pair of long strings. We show that they are indeed well defined as limits of open string amplitudes, and that our results are in striking numerical agreement with computations in the adjoint and bi-adjoint sectors of the dual matrix model (based on proposals of Maldacena and solutions due to Fidkowski), thereby providing strong evidence of the duality.

description: Artificial ice systems have been designed to replicate paradigmatic phenomena observed in frustrated spin systems. Here we present a detailed theoretical analysis based on Monte-Carlo simulations of the low energy phases in an artificial colloidal ice system, a recently introduced ice system where an ensemble of repulsive colloids are two-dimensionally confined by gravity to a lattice of double wells at a one-to-one filling. Triggered by recent results obtained by Brownian dynamics simulations [A. Libál et al, Phys. Rev. Lett. 120, 027204 (2018)], we analyze the energetics and the phase transitions that occur in the honeycomb geometry (realizing the analogue of a spin ice system on a kagome lattice) when decreasing the temperature. When the particles are restricted to occupy the two minima of the potential well, we recover the same phase diagram as the dipolar spin ice system, with a long range ordered chiral ground state. In contrast, when considering the particle motion and their relaxation within the traps, we observe ferromagnetic ordering at low temperature. This observation highlights the fundamental role played by the continuous motion of the colloids in artificial ice systems.

description: Nonreciprocal microwave devices play several critical roles in high-fidelity, quantum-nondemolition (QND) measurement schemes. They separate input from output, impose unidirectional routing of readout signals, and protect the quantum systems from unwanted noise originated by the output chain. However, state-of-the-art, cryogenic circulators and isolators are disadvantageous in scalable superconducting quantum processors because they use magnetic materials and strong magnetic fields. Here, we realize an active isolator formed by coupling two nondegenerate Josephson mixers in an interferometric scheme. Nonreciprocity is generated by applying a phase gradient between the same-frequency pumps feeding the Josephson mixers, which play the role of the magnetic field in a Faraday medium. To demonstrate the applicability of this Josephson-based isolator for quantum measurements, we incorporate it into the output line of a superconducting qubit, coupled to a fast resonator and a Purcell filter. We also utilize a wideband, superconducting directional coupler for coupling the readout signals into and out of the qubit-resonator system and a quantum-limited Josephson amplifier for boosting the readout fidelity. By using this novel quantum setup, we demonstrate fast, high-fidelity, QND measurements of the qubit while providing more than 20 dB of protection against amplified noise reflected off the Josephson amplifier.

description: We investigate the double-layer electron system in a parabolic quantum well at filling factor $ν=2$ in a tilted magnetic field using capacitance spectroscopy. The competition between two ground states is found at the Zeeman splitting appreciably smaller than the symmetric-antisymmetric splitting. Although at the transition point the system breaks up into domains of the two competing states, the activation energy turns out to be finite, signaling the occurrence of a new insulator-insulator quantum phase transition. We interpret the obtained results in terms of a predicted canted antiferromagnetic phase.

description: Should a central bank take over the provision of e-money, a circulable electronic liability? We discuss how e-money technology changes the tradeoff between public and private provision, and the tradeoff between e-money and a central bank's existing liabilities like bank notes and reserves. The tradeoffs depend on i) the technological setup of the e-money system (as a token or an account; centralized or decentralized); ii) the potential improvement in the implementation and transmission of monetary policy; iii) the risks to safety and privacy from cyber attacks; and iv) the uncertain impact on banks’ efficiency and financial stability. The most compelling argument for central banks to issue e-money is to address competition problems in the banking sector.
description: Une banque centrale devrait-elle prendre en charge l’émission de monnaie électronique, un passif électronique voué à circuler dans l’économie? Nous analysons la manière dont la technologie sur laquelle repose cette monnaie vient modifier les avantages et les inconvénients respectifs, d’une part, de son émission par une autorité publique et par une entité privée et, d’autre part, de la monnaie électronique et du passif existant de la banque centrale (billets de banque et réserves, par exemple). Ces avantages et inconvénients dépendent des facteurs suivants : i) les caractéristiques technologiques du système de monnaie électronique (jetons ou comptes; système centralisé ou décentralisé); ii) l’amélioration possible de la mise en oeuvre et de la transmission de la politique monétaire; iii) les risques d’atteinte à la sécurité et à la vie privée que posent les cyberattaques; et iv) les répercussions incertaines sur l’efficience des banques et la stabilité financière. La prise en main des problèmes de concurrence dans le secteur bancaire est l’argument qui plaide le plus en faveur de l’émission de monnaie électronique par les banques centrales.

description: We discuss stationary solutions of the discrete nonlinear Schrödinger equation (DNSE) with a potential of the $ϕ^{4}$ type which is generically applicable to several quantum spin, electron and classical lattice systems. We show that there may arise chaotic spatial structures in the form of incommensurate or irregular quantum states. As a first (typical) example we consider a single electron which is strongly coupled with phonons on a $1D$ chain of atoms --- the (Rashba)--Holstein polaron model. In the adiabatic approximation this system is conventionally described by the DNSE. Another relevant example is that of superconducting states in layered superconductors described by the same DNSE. Amongst many other applications the typical example for a classical lattice is a system of coupled nonlinear oscillators. We present the exact energy spectrum of this model in the strong coupling limit and the corresponding wave function. Using this as a starting point we go on to calculate the wave function for moderate coupling and find that the energy eigenvalue of these structures of the wave function is in exquisite agreement with the exact strong coupling result. This procedure allows us to obtain (numerically) exact solutions of the DNSE directly. When applied to our typical example we find that the wave function of an electron on a deformable lattice (and other quantum or classical discrete systems) may exhibit incommensurate and irregular structures. These states are analogous to the periodic, quasiperiodic and chaotic structures found in classical chaotic dynamics.

description: Motivated by the recent observation of the metal-insulator transition in Si-MOSFETs we consider the quantum interference correction to the conductivity in the presence of the Rashba spin splitting. For a small splitting, a crossover from the localizing to antilocalizing regime is obtained. The symplectic correction is revealed in the limit of a large separation between the chiral branches. The relevance of the chiral splitting for the 2D electron gas in Si-MOSFETs is discussed.

description: We build upon new developments in the international trade literature to isolate and quantify the long-run economic impacts of tariff changes on the United States and the global economy. In particular, we apply the most recent data and trade elasticity estimates to the Ricardian model of Caliendo and Parro (2015) to quantify the long-run impacts of the recently applied and proposed tariff changes, including the U.S. tariffs on steel and aluminum imports and the rounds of additional tariffs between the United States and China. To fit the reality of the current trade policy shift, our analysis also allows for quotas and endogenizes trade balances. Overall, our results suggest that the newly imposed and proposed tariff schemes imply considerable changes in trade flows and sectoral output reallocations, but modest impacts on long-run aggregate prices and output levels.
description: Nous nous appuyons sur les travaux récents de la littérature consacrée au commerce international pour isoler et quantifier les effets économiques à long terme des modifications des droits de douane sur les États-Unis et l’économie mondiale. Nous intégrons les données les plus récentes et nos estimations de l’élasticité des échanges commerciaux au modèle ricardien de Caliendo et Parro (2015), afin de calculer l’incidence économique à long terme des droits de douane récemment imposés et proposés, y compris les droits sur les importations d’acier et d’aluminium mis en place par l’administration américaine et les séries de droits de douane supplémentaires appliqués entre les États-Unis et la Chine. Pour rendre compte de l’orientation actuelle de la politique commerciale, notre cadre d’analyse inclut les quotas et endogénéise les balances commerciales. Dans l’ensemble, les résultats obtenus semblent indiquer que les nouveaux droits de douane imposés et proposés ont des répercussions considérables sur les flux commerciaux et la réallocation de la production entre les secteurs. Toutefois, nous estimons que les conséquences à long terme sont modestes sur le niveau général des prix et les niveaux de production.

description: We have generalized the network approach to include the effects of short-range imperfections in order to analyze recent experiments on mesoscopic superconducting double loops. The presence of weakly scattering imperfections causes gaps in the phase boundary $B(T)$ or $Φ(T)$ for certain intervals of $T$, which depend on the magnetic flux penetrating each loop. This is accompanied by a critical temperature $T_c(Φ)$, showing a smooth transition between symmetric and antisymmetric states. When the scattering strength of imperfections increases beyond a certain limit, gaps in the phase boundary $T_c(B)$ or $T_c(Φ)$ appear for values of magnetic flux lying in intervals around half-integer $Φ_0=hc/2e$. The critical temperature corresponding to these values of magnetic flux is determined mainly by imperfections in the central branch. The calculated phase boundary is in good agreement with experiment.

We characterize residually finite tubular groups: $G$ is residually finite if and only if its edge groups are separable. Methods are provided to determine if $G$ is residually finite. When $G$ has a single vertex group an algorithm is given to determine residual finiteness.
