description: Aged and damaged mitochondria can be selectively degraded by specific autophagic elimination, termed mitophagy. Defects in mitophagy have been increasingly linked to several diseases including neurodegenerative diseases, metabolic diseases and other aging-related diseases. However, the molecular mechanisms of mitophagy are not fully understood. Here, we identify PRPF8 (pre-mRNA processing factor 8), a core component of the spliceosome, as an essential mediator in hypoxia-induced mitophagy from an RNAi screen based on a fluorescent mitophagy reporter, mt-Keima. Knockdown of PRPF8 significantly impairs mitophagosome formation and subsequent mitochondrial clearance through the aberrant mRNA splicing of ULK1, which mediates macroautophagy/autophagy initiation. Importantly, autosomal dominant retinitis pigmentosa (adRP)-associated PRPF8 mutant R2310K is defective in regulating mitophagy. Moreover, knockdown of other adRP-associated splicing factors, including PRPF6, PRPF31 and SNRNP200, also lead to ULK1 mRNA mis-splicing and mitophagy defects. Thus, these findings demonstrate that PRPF8 is essential for mitophagy and suggest that dysregulation of spliceosome-mediated mitophagy may contribute to pathogenesis of retinitis pigmentosa.

description: Tissue microstructure has significance as a biomarker, however its accurate inference with diffusion magnetic resonance (MR) is still an open problem. With few exceptions, diffusion weighted (DW) MR models either process diffusion MR data using signal magnitude, whereby microstructural information is forcefully confined to symmetry due to Fourier transform properties, or directly use symmetric basis expansions. Herein, information loss from magnitude utilization is demonstrated by numerically simulating particles undergoing diffusion near a fully reflective infinite wall and an orthogonal corner. Simulation results show that the loss of the Hermitian property when using signal magnitude impedes DW--MR from accurately inferring microstructural information in both of the geometries.

title: Volatility Forecasting when the Noise Variance Is Time-Varying

Publisher: name: Bank of Canada
Year: 2013

description: This paper explores the volatility forecasting implications of a model in which the friction in high-frequency prices is related to the true underlying volatility. The contribution of this paper is to propose a framework under which the realized variance may improve volatility forecasting if the noise variance is related to the true return volatility. The realized variance is defined as the sum of the squared intraday returns. When based on high-frequency returns, the realized variance would be non-informative for the true volatility under the standard framework. In this new setting, we revisit the results of Andersen et al. (2011) and quantify the predictive ability of several measures of integrated variance. Importantly, the time-varying aspect of the noise variance implies that the forecast of the integrated variance is different from the forecast of a realized measure. We characterize this difference, which is time-varying, and propose a feasible bias correction. We assess the usefulness of our approach for realistic models, then study the empirical implication of our method when dealing with forecasting integrated variance or trading options. The empirical results for Alcoa stock show several improvements resulting from the assumption of time-varying noise variance.

description: Les auteurs analysent l’apport, pour la prévision de la volatilité, d’un modèle dans lequel une relation est établie entre la volatilité fondamentale et les frictions qui caractérisent les prix observés à haute fréquence. L’originalité de leur approche réside dans le fait que, du moment où la variance du bruit est liée à la volatilité fondamentale des rendements, ce modèle est susceptible d’améliorer les prévisions de la volatilité basées sur la variance réalisée. Celle-ci est définie par la somme des carrés des rendements intrajournaliers. Lorsqu’elle est calculée à partir de rendements de haute fréquence, la variance réalisée ne fournit aucune information sur la volatilité fondamentale dans le cadre du modèle classique. Avec leur nouveau modèle, les auteurs réexaminent les résultats de l’étude d’Andersen et autres (2011) et quantifient le pouvoir de prévision de plusieurs mesures de la variance intégrée. Le fait que la variance du bruit ne soit pas constante dans le temps a un important corollaire : les prévisions relatives à la variance intégrée diffèrent des mesures de la volatilité réalisée. Les auteurs caractérisent cette différence, elle-même variable dans le temps, et proposent une méthode qui permet de corriger le biais. Ils évaluent l’utilité de leur approche pour des modèles réalistes et en étudient l’apport empirique pour la prévision de la variance intégrée ou les transactions d’options. Appliquée au titre Alcoa, leur méthode, en particulier la forme spécifique d’hétéroscédasticité du bruit, conduit à des améliorations.

description: In this article, we describe screening, a new Stata command for data management that can be used to examine the content of complex narrative-text variables to identify one or more user-defined keywords. The command is useful when dealing with string data contaminated with abbreviations, typos, or mistakes. A rich set of options allows a direct translation from the original narrative string to a user-defined standard coding scheme. Moreover, screening is flexible enough to facilitate the merging of information from different sources and to extract or reorganize the content of string variables.

description: Optical tweezers are widely used for the manipulation of cells and their internal structures. However, the degree of manipulation possible is limited by poor control over the orientation of trapped cells. We show that it is possible to controllably align or rotate disc shaped cells - chloroplasts of Spinacia oleracea - in a plane polarised Gaussian beam trap, using optical torques resulting predominantly from circular polarisation induced in the transmitted beam by the non-spherical shape of the cells.

description: We discuss the X-ray, optical and radio properties of AX J0843+2942, a high luminosity Type 2 AGN found in the ASCA Hard Serendipitous Survey. The X-ray spectrum is best described by an absorbed power-law model with photon index of Gamma = 1.72 (+0.3 -0.6) and intrinsic absorbing column density of NH = 1.44 (+0.33 -0.52) x 10E23 cm-2. The intrinsic luminosity in the 0.5-10 keV energy band is ~ 3x10E45 erg s-1, well within the range of quasar luminosities. AX J0843+2942, positionally coincident with the core of a triple and strong (S_1.4 GHz ~ 1 Jy; P_1.4 GHz ~ 9 x 10E33 erg s-1 Hz-1) radio source, is spectroscopically identified with a Narrow Line object (intrinsic FWHM of all the permitted emission lines <= 1200 km s-1) at z=0.398, having line features and ratios typical of Seyfert-2 like objects. The high X-ray luminosity, coupled with the high intrinsic absorption, the optical spectral properties and the radio power, allow us to propose AX J0843+2942 as a Radio-Loud "Type 2 QSO". A discussion of the SED of this object is presented here together with a comparison with the SED of Ultra Luminous Infrared Galaxies, other "Type 2 QSO" candidates from the literature, and "normal" Radio-Quiet and Radio-Loud QSOs.

description: Polarized Raman spectra of the calcium vanadium oxide bronze beta-Ca0.33V2O5 are measured in the temperature range between 300 K and 20 K. The charge ordering phase transition at about 150 K is characterized by the appearance of the new Raman-active modes in the spectra, and by anomalies in the electronic background scattering. The high temperature Raman scattering spectra of beta-Ca0.33V2O5 are in apparent resemblance with those of alpha'-NaV2O5, which suggests that there is a similar charge-phonon dynamics in both compounds. The study of dynamical properties and the symmetry analysis of the Raman modes show that in the mixed valence state of beta-Ca0.33V2O5 the electrons are delocalized into V1-O5-V3 orbitals. We propose that in the charge ordered state below 150 K the d-electrons localize within V1-V3 ladders, either in "zig-zag" fashion like in alpha'-NaV2O5 or in the forms of the double chains like in gamma-LiV2O5.

title: A Distributional Approach to Realized Volatility
Creators: name: Chaker, Selma
name: Meddahi, Nour
Publisher: name: Bank of Canada
Year: 2013

description: This paper proposes new measures of the integrated variance, measures which use high-frequency bid-ask spreads and quoted depths. The traditional approach assumes that the mid-quote is a good measure of frictionless price. However, the recent high-frequency econometric literature takes the mid-quote as a noisy measure of the frictionless price and proposes new and robust estimators of the integrated variance. This paper forgoes the common assumption of an additive friction term, and demonstrates how the quoted depth may be used in the construction of refined realized volatility measures under the assumption that the true frictionless price lies between the bid and the ask. More specifically, we make assumptions about the conditional distribution of the frictionless price given the available information, including quotes and depths. This distributional assumption leads to new measures of the integrated variance that explicitly incorporate the depths. We then empirically compare the new measures with the robust ones when dealing with forecasting integrated variance or trading options. We show that, in several cases, the new measures dominate the traditional measures.
description: Les auteurs proposent de nouvelles mesures de la variance intégrée qui reposent sur des données à haute fréquence concernant les écarts entre cours acheteur et vendeur et les profondeurs affichées, c.-à-d. les quantités offertes à ces deux cours. Dans l’approche traditionnelle, le cours médian est considéré comme un bon indicateur du prix sans frictions. Or les travaux économétriques récents ayant mis à contribution ce type de données voient dans le cours médian une mesure entachée de bruit et proposent plutôt l’emploi de nouveaux estimateurs de la variance intégrée qui sont robustes. Dans la présente étude, les auteurs n’incluent pas de terme de friction de type additif, contrairement aux modèles classiques, et démontrent que les profondeurs affichées peuvent servir à construire des mesures plus précises de la volatilité réalisée en partant de l’hypothèse que le prix sans frictions se situe entre les cours vendeur et acheteur. Plus précisément, ils formulent des hypothèses au sujet de la distribution conditionnelle du prix sans frictions étant donné l’information disponible, dont les cours et profondeurs affichés. Grâce à ces hypothèses, il est possible d’élaborer des mesures de la variance intégrée qui tiennent compte explicitement des profondeurs affichées. Les auteurs comparent ensuite les nouvelles mesures avec des estimateurs robustes afin d’en évaluer l’apport empirique pour la prévision de la variance intégrée ou les transactions d’options. Dans plusieurs cas, les nouvelles mesures surpassent celles couramment utilisées.

Year: 2013

description: We examine the extent to which vertical and horizontal market structure can together explain incomplete retail pass-through. To answer this question, we use scanner data from a large U.S. retailer to estimate product level pass-through for three different vertical structures: national brands, private label goods not manufactured by the retailer and private label goods manufactured by the retailer. Our findings emphasize that accounting for the interaction of vertical and horizontal structure is important in understanding how market structure affects pass-through, as a reduction in double-marginalization can raise pass-through directly but can also reduce it indirectly by increasing market share.
description: Les auteurs s’interrogent sur la mesure dans laquelle la structure verticale d’un marché et sa structure horizontale peuvent ensemble expliquer la transmission incomplète des coûts aux prix de détail. Pour répondre à cette question, ils estiment, à l’aide de données provenant d’un important détaillant américain recueillies par balayage optique, le degré de transmission des coûts selon les produits, pour trois structures verticales différentes : marques nationales, marques de distributeur non fabriquées par le détaillant et marques de distributeur fabriquées par lui. D’après les résultats de l’étude, il faut tenir compte de l’interaction des structures verticale et horizontale si l’on veut comprendre comment la structure d’un marché influe sur le degré de répercussion des coûts, du fait que la réduction de la double marginalisation peut aussi bien faire augmenter directement ce degré que le faire diminuer indirectement par l’élargissement des parts de marché.

description: We employ a comprehensive data set and a variety of methods to provide evidence on the magnitude of large banks’ funding advantage in Canada, and on the extent to which market discipline exists across different securities issued by the Canadian banks. The banking sector in Canada provides a unique setting in which to examine market discipline along with the prospects of proposed reforms, because Canada has no history of government bailouts. Our results suggest that large banks likely have a funding advantage over small banks after controlling for bank-specific and market risk factors. Working with hand-collected market data on debt issues by large banks, we also find that market discipline exists for subordinated debt and not for senior debt.
description: À l’aide d’un ensemble exhaustif de données et de méthodes variées, les auteurs cherchent à établir, d’une part, l’importance des avantages de financement des grandes banques au Canada et, d’autre part, le degré auquel la discipline de marché s’applique aux différents titres émis par les banques du pays. Le secteur bancaire canadien constitue un cadre unique pour étudier la discipline de marché ainsi que l’applicabilité des réformes proposées, du fait qu’aucun établissement n’a jamais été renfloué par l’État. Après avoir pris en compte des facteurs de risque propres à chaque établissement et les facteurs de risque communs au marché, ils constatent que les grandes banques semblent jouir d’un avantage de financement sur les petites. S’appuyant sur des données de marché qu’ils ont recueillies manuellement au sujet des titres d’emprunt émis par les grandes banques, les auteurs découvrent également que la discipline de marché s’applique aux titres de dette subordonnée mais non aux titres de premier rang.

description: This paper deals with the estimation of the risk-return trade-off. We use a MIDAS model for the conditional variance and allow for possible switches in the risk-return relation through a Markov-switching specification. We find strong evidence for regime changes in the risk-return relation. This finding is robust to a large range of specifications. In the first regime characterized by low ex-post returns and high volatility, the risk-return relation is reversed, whereas the intuitive positive risk-return trade-off holds in the second regime. The first regime is interpreted as a “flight-to-quality” regime.
description: Notre étude porte sur l’estimation de la relation entre le risque et le rendement. À cette fin, nous estimons cette relation avec un modèle à changements de régimes markoviens en utilisant un modèle MIDAS pour la variance conditionnelle. Les résultats obtenus à partir de nombreuses spécifications militent fortement en faveur de changements de régimes dans la relation entre le risque et le rendement. Dans le premier régime, caractérisé par de faibles rendements ex post et une forte volatilité, la relation entre le risque et le rendement est négative; à l’inverse, la relation de ces deux éléments est positive dans le second régime comme le prévoit le modèle théorique. Le premier régime constitue selon nous un mouvement de report vers la qualité.

description: In recent years, promising deep learning based interatomic potential energy surface (PES) models have been proposed that can potentially allow us to perform molecular dynamics simulations for large scale systems with quantum accuracy. However, making these models truly reliable and practically useful is still a very non-trivial task. A key component in this task is the generation of datasets used in model training. In this paper, we introduce the Deep Potential GENerator (DP-GEN), an open-source software platform that implements the recently proposed "on-the-fly" learning procedure [Phys. Rev. Materials 3, 023804] and is capable of generating uniformly accurate deep learning based PES models in a way that minimizes human intervention and the computational cost for data generation and model training. DP-GEN automatically and iteratively performs three steps: exploration, labeling, and training. It supports various popular packages for these three steps: LAMMPS for exploration, Quantum Espresso, VASP, CP2K, etc. for labeling, and DeePMD-kit for training. It also allows automatic job submission and result collection on different types of machines, such as high performance clusters and cloud machines, and is adaptive to different job management tools, including Slurm, PBS, and LSF. As a concrete example, we illustrate the details of the process for generating a general-purpose PES model for Cu using DP-GEN.

The limits, or approximations to them, have repeatedly been rediscovered over the last several decades, but nevertheless seem to remain only poorly known. The limits impart bias to estimation and, in extreme cases, imply that no sample could bear exact witness to its parent distribution. The main results are explained in a tutorial review, and it is shown how Stata and Mata may be used to confirm and explore their consequences.

description: We have performed in-plane transport measurements on the two-dimensional organic salt $κ$-(BEDT-TTF)$_{2}$Cu[N(CN)$_{2}$]Cl. A variable (gas) pressure technique allows for a detailed study of the changes in conductivity through the insulator-to-metal transition. We identify four different transport regimes as a function of pressure and temperature (corresponding to insulating, semi-conducting, ''bad metal'', and strongly correlated Fermi liquid behaviours). Marked hysteresis is found in the transition region, which displays complex physics that we attribute to strong spatial inhomogeneities. Away from the critical region, good agreement is found with a dynamical mean-field calculation of transport properties using the numerical renormalization group technique.

description: We report on the discovery of a peculiar Broad Absorption Line (BAL) quasar identified in our Gaia-assisted survey of red quasars. The systemic redshift of this quasar was difficult to establish due to the absence of conspicuous emission lines. Based on deep and broad BAL troughs (at least SiIV, CIV, and AlIII), a redshift of z=2.41 was established under the assumption that the systemic redshift can be inferred from the red edge of the BAL troughs. However, we observe a weak and spatially-extended emission line at 4450 AA most likely due to Lyman-alpha emission, which implies a systemic redshift of z=2.66 if correctly identified. There is also evidence for the onset of Lyman-alpha forest absorption bluewards of 4450 AA and evidence for H-alpha emission in the K-band consistent with a systemic redshift of z=2.66. If this redshift is correct, the quasar is an extreme example of a detached low-ionisation BAL quasar. The BAL lines must originate from material moving with very large velocities ranging from 22000 to 40000 km/s. To our knowledge, this is the first case of a systemic-redshift measurement based on extended Lyman-$α$ emission for a BAL quasar, a method that should also be useful in cases of sufficiently distant BL Lac quasars without systemic-redshift information.

description: Ambisonics i.e., a full-sphere surround sound, is quintessential with 360-degree visual content to provide a realistic virtual reality (VR) experience. While 360-degree visual content capture gained a tremendous boost recently, the estimation of corresponding spatial sound is still challenging due to the required sound-field microphones or information about the sound-source locations. In this paper, we introduce a novel problem of generating Ambisonics in 360-degree videos using the audio-visual cue. With this aim, firstly, a novel 360-degree audio-visual video dataset of 265 videos is introduced with annotated sound-source locations. Secondly, a pipeline is designed for an automatic Ambisonic estimation problem. Benefiting from the deep learning-based audio-visual feature-embedding and prediction modules, our pipeline estimates the 3D sound-source locations and further use such locations to encode to the B-format. To benchmark our dataset and pipeline, we additionally propose evaluation criteria to investigate the performance using different 360-degree input representations. Our results demonstrate the efficacy of the proposed pipeline and open up a new area of research in 360-degree audio-visual analysis for future investigations.

description: Using the IRAM 30m telescope, we have surveyed an unbiased sample of 47 nearby spiral galaxies of very late (Scd-Sm) Hubble-type for emission in the CO(1-0) and CO(2-1) lines. The sensitivity of our data (a few mK) allows detection of about 60% of our sample in at least one of the CO lines. The median detected H2 mass is $1.4\times 10^7 \msun$ within the central few kpc, assuming a standard conversion factor. We use the measured line intensities to complement existing studies of the molecular gas content of spiral galaxies as a function of Hubble-type and to significantly improve the statistical significance of such studies at the late end of the spiral sequence. We find that the latest-type spirals closely follow the correlation between molecular gas content and galaxy luminosity established for earlier Hubble types. The molecular gas in late-type galaxies seems to be less centrally concentrated than in earlier types. We use Hubble Space Telescope optical images to correlate the molecular gas mass to the properties of the central galaxy disk and the compact star cluster that occupies the nucleus of most late-type spirals. There is no clear correlation between the luminosity of the nuclear star cluster and the molecular gas mass, although the CO detection rate is highest for the brightest clusters. It appears that the central surface brightness of the stellar disk is an important parameter for the amount of molecular gas at the galaxy center. Whether stellar bars play a critical role for the gas dynamics remains unclear, in part because of uncertainties in the morphological classifications of our sample.

description: Despite various payment innovations, today, cash is still heavily used to pay for low-value purchases. This paper develops a simulation model to test whether standard implications of the theory on cash management and payment choices can explain the use of payment instruments by transaction size. In particular, using diary survey data from Canada, France, Germany and the Netherlands, we test the assumption that cash is still the most efficient payment instrument, and the idea that people hold cash for precautionary reasons when facing uncertainty about their future purchases. The results of the simulations show that these two factors are significant determinants of the high shares of low-value cash payments in Canada, France and Germany. Yet, they are not so crucial in the Netherlands, which exhibits a significant share of low-value card transactions. We discuss how the differences in payment markets across countries may explain the differences in the performance of the model.
description: En dépit des nombreuses innovations en matière de paiement, les espèces sont aujourd’hui encore très utilisées pour régler les achats de faible valeur. Dans cette étude, les auteurs élaborent un modèle de simulation pour déterminer si les modèles standard de la théorie sur la gestion des espèces et les choix des moyens de paiement permettent d’expliquer l’usage d’un instrument de paiement en fonction de la valeur de la transaction. Plus précisément, à l’aide de données issues d’enquêtes menées au Canada, en France, en Allemagne et aux Pays-Bas et comportant la tenue de journaux d’achats, ils testent l’hypothèse selon laquelle les espèces restent le mode de paiement le plus efficient et l’idée que les agents gardent une réserve d’argent pour des motifs de précaution afin de faire face à l’incertitude de leurs achats futurs. Les résultats des simulations montrent que ces deux facteurs expliquent en grande partie les parts élevées des espèces dans les achats de petits montants au Canada, en France et en Allemagne. L’incidence de ces facteurs est toutefois moins marquée aux Pays-Bas, où une part importante des transactions de faible valeur est réglée par carte de paiement. Les auteurs examinent de quelle manière les différences entre les marchés des paiements des pays à l’étude peuvent expliquer les performances du modèle.

description: All optical techniques used to probe the properties of Bose-Einstein condensates have been based on dispersion and absorption that can be described by a two-level atom. Both phenomena lead to spontaneous emission that is destructive. Recently, both were shown to lead to the same limit to the signal to noise ratio for a given destruction. We generalise this result to show that no single-pass optical technique using classical light, based on any number of lasers or coherences between any number of levels, can exceed the limit imposed by the two-level atom. This puts significant restrictions on potential non-destructive measurement schemes.

High Accretion Rate during Class 0 Phase due to External Trigger

description: Recent observations indicate that some class 0 sources have orders of magnitude higher accretion rates than those of class I. We investigated the conditions for the high accretion rates of some class 0 sources by numerical calculations, modelling an external trigger. For no external trigger, we find that the maximum value of the accretion rate is determined by the ratio $α$ of the gravitational energy to the thermal one within a flat inner region of the cloud core. The accretion rate reaches $\sim 10^{-4} M_{\sun} yr^{-1}$ if the cloud core has $ α> 2$. For an external trigger we find that the maximum value of the accretion rate is proportional to the momentum given to the cloud core. The accretion rate reaches $ > 10^{-4} M_{\sun} yr^{-1}$ with a momentum of $\sim 0.1 M_{\sun} km s^{-1}$ when the initial central density of the cloud core is $\sim 10^{-18} g cm^{-3}$. A comparison between recent observational results for prestellar cores and our no triggered collapse model indicates that the flat inner regions of typical prestellar cores are not large enough to cause accretion rates of $\sim 10^{-4} M_{\sun} yr^{-1}$. Our results show that the triggered collapse of the cloud core is more preferable for the origin of the high accretion rates of class 0 sources than no triggered collapse.

description: Gesture recognition and hand motion tracking are important tasks in advanced gesture based interaction systems. In this paper, we propose to apply a sliding windows filtering approach to sample the incoming streams of data from data gloves and a decision tree model to recognize the gestures in real time for a manual grafting operation of a vegetable seedling propagation facility. The sequence of these recognized gestures defines the tasks that are taking place, which helps to evaluate individuals' performances and to identify any bottlenecks in real time. In this work, two pairs of data gloves are utilized, which reports the location of the fingers, hands, and wrists wirelessly (i.e., via Bluetooth). To evaluate the performance of the proposed framework, a preliminary experiment was conducted in multiple lab settings of tomato grafting operations, where multiple subjects wear the data gloves while performing different tasks. Our results show an accuracy of 91% on average, in terms of gesture recognition in real time by employing our proposed framework.

title: A Tractable Monetary Model Under General Preferences

description: Consider the monetary model of Lagos and Wright (JPE 2005) but with general preferences and general production. I show that preferences satisfying UXXUHH – (UXH)2 = 0 is a sufficient condition for the existence and uniqueness of monetary equilibrium with degenerate money distribution. I solve for the entire class of exact solutions to the above non-linear second order partial differential equation. This class of preferences includes ones with constant return to scale, for example, constant elasticity of substitution (CES), and ones used in many other macroeconomics literatures. I also analyze the welfare implication of monetary policy in this economy.
description: En se fondant sur le modèle monétaire de Lagos et Wright (JPE, 2005), mais en introduisant des préférences générales et une production générale, l’auteur montre que les préférences qui satisfont l’équation différentielle partielle et non linéaire du second ordre UXXUHH – (UXH)2 = 0 forment une condition suffisante de l’existence et de l’unicité d’un équilibre monétaire avec distribution dégénérée de la monnaie. Il résout l’équation pour une classe entière de solutions exactes. Cette classe de préférences comporte des préférences à rendements d’échelle constants (cas de l’élasticité de substitution constante dite CES) et des préférences comme en énoncent de nombreux travaux de macroéconomie. L’auteur analyse également les incidences de la politique monétaire sur le bien-être des agents de son modèle.
