description: Amorphophallus coaetaneus S. Y. Liu & S. J. Wei 1986 is a perennial herb belonging to the Araceae family in southwestern China (Guangxi and Yunnan provinces). Although this species have not been list in the red list of International Union for Conservation of Nature (IUCN), the populations are declining due to human over exploitation. To help to genetic diversity studies, we sequenced and assembled the complete chloroplast (cp) genome of A. coaetaneus (GenBank accession number of national center for biotechnology information (NCBI): OQ404947). The assembled genome revealed 175,465 bp in length with a GC content of 34.90%, including a large single-copy (LSC) region (98,561 bp), a small single-copy (SSC) region (16,504 bp) and two inverted repeat regions (IRs) (30,200 bp each). A total of 133 genes were annotated, of which 85 are protein-coding genes, 40 are tRNA genes and 8 are rRNA genes. As an output of this study, a maximum likelihood (ML) phylogenetic inference of 16 Araceae species clustered all four Amorphophallus species in one clade, and showed a relatively close relationship between the tribes Pythonieae and Colocasieae. The cp genome will serve as a basis in a more extensive molecular works covering all possible extant population of Amorphophallus, as well as conservation, breeding, and other ethnobotanical utilization of this species.

description: The recent reversal in the intraregional migration into nonmetropolitan areas has generated a great deal of interest in the problems of local government finance .. or specific concern are the changes in local government expenditures and revenues that have accompanied population growth and decline and related shifts in population composition in nonmetropolitan areas of the Northeast. Using a supply and demand framework, it is argued that the approach used in previous studies of examining the relationship between growth rates and various fiscal variables leads to biased inferences regarding the impact of growth. By analyzing the impacts of changes in the socioeconomic make-up of the population which often accompany growth and decline, the study increases the understanding of fiscal strains on local governments resulting from population shifts.
title: Is Hysteresis a Characteristic of the Canadian Labour Market? A Tale of Two Studies
Creators: name: Poloz, Stephen S.

Publisher: name: Bank of Canada
Year: 1992

description: This paper replicates and extends the econometric work of two previous studies of output-inflation dynamics in Canada -- Fortin (1991) and Cozier and Wilkinson (1991) -- in an attempt to reconcile their divergent conclusions. The former paper finds that the Canadian labour market exhibited hysteresis during the 1973-90 period, while the latter paper rejects labour market hysteresis over the period 1964-88. The approach taken in this paper is to estimate alternative specifications of the key equations presented by Cozier and Wilkinson and by Fortin, so as to isolate the main factors contributing to this difference in view. The paper then asks whether this additional information enables one to accept one inference over the other. The authors find that the available evidence against labour market hysteresis in Canada is much more compelling than evidence in favour. The paper concludes with a discussion of outstanding issues that might yet have a bearing on this question.
description: Dans la présente étude, les auteurs répètent puis élargissent les travaux économétriques effectués par Forrin (1991) et par Cozier et Wilkinson (1991) sur la dynamique liant la production et l'inflation au Canada, espérant ainsi concilier les conclusions divergentes auxquelles ceux-ci sont parvenus. Selon Fortin, le marché du travail au Canada a montré des signes d' hystérèse entre 1973 et 1990, tandis que Cozier et Wilkinson rejettent cette hypothèse pour la période 1964-1988. Les auteurs de la présente étude ont pris le parti d'estimer d'autres spécifications des équations clés présentées par ces chercheurs, de manière à isoler les principaux facteurs contribuant a leur divergence de vues. Ils analysent ensuite l'information supplémentaire ainsi obtenue et constatent que les résultats invalidant l'hypothèse d'hystérèse du marché du travail au Canada sont beaucoup plus robustes que ceux qui l'appuient. En terminant, les auteurs signalent certaines questions qui demeurent autour de cette problématique.

description: We study what are the factors that can accelerate the emergence of collaborative behaviours among independent selfish learning agents. We depart from the "Battle of the Exes" (BoE), a spatial repeated game from which human behavioral data has been obtained (by Hawkings and Goldstone, 2016) that we find interesting because it considers two cases: a classic game theory version, called ballistic, in which agents can only make one action/decision (equivalent to the Battle of the Sexes) and a spatial version, called dynamic, in which agents can change decision (a spatial continuous version). We model both versions of the game with independent reinforcement learning agents and we manipulate the reward function transforming it into an utility introducing "loss aversion": the reward that an agent obtains can be perceived as less valuable when compared to what the other got. We prove experimentally the introduction of loss aversion fosters cooperation by accelerating its appearance, and by making it possible in some cases like in the dynamic condition. We suggest that this may be an important factor explaining the rapid converge of human behaviour towards collaboration reported in the experiment of Hawkings and Goldstone.

description: Using BoC-GEM-Fin, a large-scale DSGE model with real, nominal and financial frictions featuring a banking sector, we explore the macroeconomic implications of various types of countercyclical bank capital regulations. Results suggest that countercyclical capital requirements have a significant stabilizing effect on key macroeconomic variables, but mostly after financial shocks. Moreover, the bank capital regulatory policy and monetary policy interact, and this interaction is contingent on the type of shocks that drive the economic cycle.

Finally, we analyze loss functions based on macroeconomic and financial variables to arrive at an optimal countercyclical regulatory policy in a class of simple implementable Taylor-type rules. Compared to bank capital regulatory policy, monetary policy is able to stabilize the economy more efficiently after real shocks. On the other hand, financial shocks require the regulator to be more aggressive in loosening/tightening capital requirements for banks, even as monetary policy works to counter the deviations of inflation from the target.
description: Les auteurs explorent les implications macroéconomiques de différents niveaux de contracyclicité des exigences de fonds propres bancaires en se servant du modèle BOC-GEM- FIN, un modèle d’équilibre général dynamique et stochastique de grande taille qui comporte des frictions réelles, nominales et financières ainsi qu’un secteur bancaire. Les résultats obtenus indiquent que l’instauration d’exigences de fonds propres contracycliques a un effet stabilisateur sur les principales variables macroéconomiques, mais cet effet est surtout notable après un choc financier. En outre, il existe une interaction entre la politique de réglementation des fonds propres bancaires et la politique monétaire, et cette interaction est tributaire du type de chocs qui sont à l’origine des fluctuations économiques.

Enfin, les auteurs analysent des fonctions de perte reposant sur des variables macroéconomiques et financières afin de déterminer le degré de contracyclicité optimal des exigences réglementaires pour un groupe de règles à la Taylor simples et applicables. La politique monétaire est plus efficace que la politique de réglementation des fonds propres bancaires pour stabiliser l’économie après des chocs réels. Les chocs financiers, par contre, obligent l’autorité de réglementation à plus de vigueur dans l’ajustement des exigences de fonds propres, même si la politique monétaire contribue à contrer les écarts de l’inflation par rapport à la cible.

description: Consider the following evolution model, proposed in \cite{BS} by Bak and Sneppen. Put $N$ vertices on a circle, spaced evenly. Each vertex represents a certain species. We associate with each vertex a random variable, representing the `state' or `fitness' of the species, with values in $[0,1]$. The dynamics proceeds as follows. Every discrete time step, we choose the vertex with minimal fitness, and assign to this vertex, and to its two neighbours, three new independent fitnesses with a uniform distribution on $[0,1]$. A conjecture of physicists, based on simulations, is that in the stationary regime, the one-dimensional marginal distributions of the fitnesses converges, when $N \to \infty$, to a uniform distribution on $(f,1)$, for some threshold $f<1$. In this paper we consider a discrete version of this model, proposed in \cite{BK}. In this discrete version, the fitness of a vertex can be either 0 or 1. The system evolves according to the following rules. Each discrete time step, we choose an arbitrary vertex with fitness 0. If all the vertices have fitness 1, then we choose an arbitrary vertex with fitness 1. Then we update the fitnesses of this vertex and of its two neighbours by three new independent fitnesses, taking value 0 with probability $0

description: Observations of the Vela pulsar-wind nebula (PWN) with the Chandra X-ray Observatory have revealed a complex, variable PWN structure, including inner and outer arcs, a jet in the direction of the pulsar's proper motion, and a counter-jet in the opposite direction, embedded in diffuse nebular emission. From the analysis of thirteen Chandra observations spread over about 2.5 years we found that this outer jet shows particularly strong variability, changing its shape and brightness. We observed bright blobs in the outer jet moving away from the pulsar with apparent speeds (0.3-0.6)c and fading on time-scales of days to weeks. The spectrum of the outer jet fits a power-law model with a photon index of 1.3. The X-ray emission of the outer jet can be interpreted as synchrotron radiation of ultrarelativistic electrons/positrons. This interpretation allows one to estimate the magnetic field, ~100 microGauss, maximum energy of X-ray emitting electrons, $2 \times 10^{14}$ eV, and energy injection rate, $8\times 10^{33}$ erg/s, for the outer jet. In the summed PWN image, we see a faint, strongly bent, extension of the outer jet. The more extreme bends closer to the pulsar, as well as the apparent side motions of the outer jet, can be associated with kink instabilities of a magnetically confined, pinched jet flow. Another feature found in the summed image is a dim, 2'-long outer counter-jet, which also shows a power-law spectrum with photon index of 1.2-1.5. Southwest of the jet/counter-jet (i.e., approximately perpendicular to the direction of pulsar's proper motion), an extended region of diffuse emission is seen. Relativistic particles responsible for this radiation are apparently supplied by the outer jet.

description: The CRESST (Cryogenic Rare Event Search with Superconducting Thermometers) dark matter search experiment aims for the detection of dark matter particles via elastic scattering off nuclei in $\mathrm{CaWO_4}$ crystals. To understand the CRESST electromagnetic background due to the bulk contamination in the employed materials, a model based on Monte Carlo simulations was developed using the Geant4 simulation toolkit. The results of the simulation are applied to the TUM40 detector module of CRESST-II phase 2. We are able to explain up to $(68 \pm 16)\,\mathrm{\%}$ of the electromagnetic background in the energy range between $1\,\mathrm{keV}$ and $40\,\mathrm{keV}$.

title: An Equilibrium Analysis of the Rise in House Prices and Mortgage Debt
Creators: name: Xu, Shaofeng
Publisher: name: Bank of Canada
Year: 2013

description: This paper examines the contributions of population aging, mortgage innovation and historically low interest rates to the sharp rise in U.S. house prices and mortgage debt between 1994 and 2005. I construct an overlapping generations general equilibrium housing model and find that these three factors together account for over half of the increase in house prices and most of the increase in mortgage debt during this period. Population aging contributes to rising house prices and mortgage debt, but it accounts for only a small portion of their observed changes. Meanwhile, mortgage innovation significantly increases the mortgage borrowing of various age cohorts, but it has a trivial effect on house prices because interest rates rise due to higher demand for mortgage loans. This increases households’ savings in financial assets and leaves their housing assets nearly unchanged. The observed run-up in house prices can, however, be justified in an open-economy setting where interest rates fall due to a global saving glut. Declining interest rates force households at prime saving ages to reallocate their wealth from financial assets to housing assets, which dramatically drives up house prices.
description: L’auteur examine l’effet du vieillissement de la population, des innovations en matière de prêts hypothécaires et des taux d’intérêt historiquement bas sur l’escalade des prix des maisons et de l’endettement hypothécaire aux États-Unis entre 1994 et 2005. Il construit un modèle d’équilibre général dynamique à générations imbriquées du marché du logement et conclut qu’ensemble, les trois facteurs susmentionnés contribuent à plus de la moitié de la hausse des prix des maisons et à la majeure partie de l’augmentation de l’endettement hypothécaire durant la période étudiée. Si le vieillissement a une incidence sur la poussée des prix des maisons et de l’endettement hypothécaire, il ne compte que pour une faible proportion dans les variations observées. Quant aux innovations en matière de prêts hypothécaires, elles causent un important accroissement du crédit hypothécaire dans les divers groupes d’âge, mais elles ont un effet négligeable sur les prix des maisons, car les taux d’intérêt montent lorsque la demande de prêts hypothécaires progresse. Cette situation conduit à une hausse de l’épargne des ménages affectée aux actifs financiers et n’a pratiquement aucune influence sur leurs actifs immobiliers. Dans une économie ouverte, l’envolée des prix des habitations observée peut toutefois s’expliquer : la surabondance de l’épargne à l’échelle mondiale y fait reculer les taux d’intérêt. Cette baisse des taux pousse les ménages du groupe d’âge ayant la plus forte propension à l’épargne à réaménager leur richesse en se tournant vers les actifs immobiliers, ce qui fait bondir les prix des maisons.

description: Multicollinearity is one of several problems confronting researchers using regression analysis. This paper examines the regression model when the assumption of independence among Ute independent variables is violated. The basic properties of the least squares approach are examined, the concept of multicollinearity and its consequences on the least squares estimators are explained. The detection of multicollinearity and alternatives for handling the problem are then discussed. The alternative approaches evaluated are variable deletion, restrictions on the parameters, ridge regression and Bayesian estimation.

description: Modernization and commercialization of the smallholder agricultural sector provides the stimulus and impetus to reducing food insecurity in developing countries. This study seeks to fill the gaps in the literature particularly by comprehensive conceptualization of the drivers of commercialization at a household level and across different socio-economic and agro-ecological zonation in the wake of promotion of collective action initiatives and the newly introduced but vastly penetrating ICT tools (mobile phones). The purpose of this study is to highlighting determinants of agricultural commercialization (market participation) by the farm households in Kenya. Specifically, special focus is given to the role played by gender, collective action initiatives and information communication technologies (ICTs) as well as interaction of these factors among the farm households in Kenya. The study uses a Tobit regression model to assess the determinants of commercialization using data of 379 farm households in three different districts in Kenya. The study finds that farmer-specific characteristics, farm-specific and capital endowment variables influence the commercialization process. Female farmers are constrained from market participation; however, collective action initiatives (farmer groups) as well as use of ICT tools (mobile phones) significantly and positively influence their commercialization. The implications for policy and practice are discussed.

description: We discuss the quantum--classical correspondence in a specific dissipative chaotic system, Duffing oscillator. We quantize it on the basis of quantum state diffusion (QSD) which is a certain formulation for open quantum systems and an effective tool for analyzing complex problems numerically. We consider a sensitivity to initial conditions, `` pseudo-Lyapunov exponent '', and investigate it in detail, varying Planck constant effectively. We show that in a dissipative system there exists a certain critical stage in which the crossover from classical to quantum behavior occurs. Furthermore, we show that an effect of dissipation suppresses the occurrence of chaos in the quantum region, while it, combined with the periodic external force, plays a crucial role in the chaotic behaviors of classical system.

Além disso, é possível constatar um crescente movimento no sentido de utilizar instrumentos próprios do direito privado para permitir ao Estado atuar com maior eficiência na economia. Nesse sentido é que foram estabelecidas diversas parcerias com empresas privadas na qual o Estado adquire parcela do capital social, sem, todavia, adquirir o poder de controle da empresa.

description: This study assessed the determinants of participation and intensity of participation in collective action initiatives. It also examined the effect of participation in such initiatives on household commercialization and on household welfare (incomes). It uses a double hurdle approach (a logit regression model to examine the determinants of participation in collective action and a Poisson regression model to assess the factors that determine the intensity of participation). The study then tests the difference in mean incomes and commercialization between participants and non-participants. The study finds that farmer/household specific variables, farm specific variables, endowment variables and regional variables influence the decision to participate as well as the extent of participation in collective action initiatives. Results further indicate that there exist significant differences in output and input market participation (commercialization) and in mean incomes as a result of participation in collective action initiatives influence the decision to participate in collective action initiatives. The implication of these findings is that for collective action initiatives to be to be effective in achieve the desired goals of helping farmers commercialize, capacity of farmers (e.g. through trainings) to operate and manage them should be improved. Stronger linkages with other institutions like public institutions, credit institutions should be encouraged and fostered so as to address the needs of the farmers. The study discusses the implications of these findings for policy.

description: Utilizing the Two Micron All Sky Survey (2MASS) Second Incremental Data Release Catalog, we have retrieved near-IR magnitudes for several hundred hot subdwarfs (sdO and sdB stars) drawn from the "Catalogue of Spectroscopically Identified Hot Subdwarfs" (Kilkenny, Heber, & Drilling 1988, 1992). This sample size greatly exceeds that of previous studies of hot subdwarfs. Examining 2MASS photometry alone or in combination with visual photometry (Johnson BV or Stromgren uvby) available in the literature, we show that it is possible to identify hot subdwarf stars that exhibit atypically red IR colors that can be attributed to the presence of an unresolved late type companion. Utilizing this large sample, we attempt for the first time to define an approximately volume limited sample of hot subdwarfs. We discuss the considerations, biases, and difficulties in defining such a sample. We find that, of the hot subdwarfs in Kilkenny et al., about 40% in a magnitude limited sample have colors that are consistent with the presence of an unresolved late type companion. Binary stars are over-represented in a magnitude limited sample. In an approximately volume limited sample the fraction of composite-color binaries is about 30%.

description: [13CII] observations in several Galactic sources show that the fine-structure [12CII] emission is often optically thick (the optical depths around 1 to a few). The aim of our study is to test whether this also affects the [12CII] emission from nearby galaxies like the Large Magellanic Cloud (LMC). We observed three star-forming regions in the LMC with upGREAT on board SOFIA at the frequency of the [CII] line. The 4GHz band width covers all three hyperfine lines of [13CII] simultaneously. For the analysis, we combined the [13CII] F=1-0 and F=1-1 hyperfine components, as they do not overlap with the [12CII] line in velocity. Three positions in N159 and N160 show an enhancement of [13CII] compared to the abundance-ratio-scaled [12CII] profile. This is likely due to the [12CII] line being optically thick, supported by the fact that the [13CII] line profile is narrower than [12CII], the enhancement varies with velocity, and the peak velocity of [13CII] matches the [OI] 63um self-absorption. The [12CII] line profile is broader than expected from a simple optical depth broadening of the [13CII] line, supporting the scenario of several PDR components in one beam having varying [12CII] optical depths. The derived [12CII] optical depth at three positions (beam size of 14arcsec, corresponding to 3.4pc) is 1--3, which is similar to values observed in several Galactic sources shown in previous studies. If this also applies to distant galaxies, the [CII] intensity will be underestimated by a factor of approximately 2.

description: The rapid selection of environmentally friendly and efficient solvents is critical for improving the safety, environmental protection, and efficiency of a process. In this study, a deep neural network structure was proposed to predict the solubility of ammonia in ionic liquids based on molecular structure, combined with support vector machine (SVM), random forest (RF) and deep neural network (DNN) algorithm. In this study, a group-based quantisation method for ionic liquids was proposed. On this basis, a feature preprocessing method integrating feature selection and data standardisation was proposed. Then, the eigenvectors extracted from the molecular structure were used to predict the solubility of ammonia in ionic liquids using SVM, RF and DNN models. Based on the cross-validation optimisation model structure, three models were evaluated. Results showed that the three models yielded high prediction accuracy, and that the prediction accuracy of the MLP model was higher than those of the SVM and RF models. For the MLP model, the coefficient of determination was 0.992. The model has good prediction performance and generalisation ability. Therefore, it can be used to select the best ionic liquid ammonia absorbent accurately and efficiently.
Quantized Anomalous Hall Effect in Two-Dimensional Ferromagnets - Quantum Hall Effect from Metal -

description: We study the effect of disorder on the anomalous Hall effect (AHE) in two-dimensional ferromagnets. The topological nature of AHE leads to the integer quantum Hall effect from a metal, i.e., the quantization of $σ_{xy}$ induced by the localization except for the few extended states carrying Chern number. Extensive numerical study on a model reveals that Pruisken's two-parameter scaling theory holds even when the system has no gap with the overlapping multibands and without the uniform magnetic field. Therefore the condition for the quantized AHE is given only by the Hall conductivity $σ_{xy}$ without the quantum correction, i.e., $|σ_{xy}| > e^2/(2h)$.

description: Le présent papier pose la problématique de l’impact des politiques commerciales agricoles sur la compétitivité interne de l’agriculture dans le contexte d’un petit pays (un price taker») qui produit trois catégories de biens agricoles : les exportables, les importables et les non échangeables. Pour atteindre cet objectif, un modèle d’équilibre général à trois biens inspiré de Dornbusch (1974) et Sjaastad (1980) est utilisé. Le modèle calcule un paramètre « omega » qui permet de capter l’impact des différentes politiques. Il ressort des résultats premièrement qu’il existe une très forte substitualité dans la demande et dans l’offre des trois catégories de biens agricoles ; deuxièmement que les biens agricoles importables bénéficient plus d’incitations positives comparativement aux biens exportables et non échangeables ; troisièmement que la compétitivité interne du secteur agricole béninois est moins meilleure en situation de libre échange qu’en présence de l’intervention étatique.

description: Models of in situ oceanic subduction and underthrusting is proposed to explain the formation and exhumation of the central Qiangtang mélange belt. Some studies have suggested that continental subduction occurred in central Qiangtang, but there is a lack of definitive evidence. Thus, the role of continental subduction in the formation and evolution of the central Qiangtang mélange belt has not been fully considered. We therefore studied the origin and structural evolution of the central Qiangtang mélange belt. Detrital zircon research indicates that the continental blocks in the Gangma Co mélange are part of the Carboniferous-Permian strata of the South Qiangtang terrane and have a Gondwanan affinity. Structural studies and geologic observations in the Gangma Co area show a change in the structural style and a pressure difference between the lower mélange and the upper Carboniferous-Permian strata. Structures in the Gangma Co mélange include D1 layer-parallel ductile structures, D2 horizontal contractional structures, D3 flattening structures, and D4 slightly horizontal contractional structures. According to our analysis, the newly proposed in situ continental subduction model best explain these findings.

description: The second neighbor correlation functions of the spin-${1/2}$ $XXZ$ chain in the ground state are expressed in the form of three dimensional integrals. We show that these integrals can be reduced to one-dimensional ones and thereby evaluate the values of the next nearest-neighbor correlation functions for ${Δ>1}$.

description: Aims. Our aim is to estimate the intergalactic medium transmission towards UV-selected star-forming galaxies at redshift 4 and above and study the effect of the dust attenuation on these measurements. Methods. The ultra-violet spectrum of high redshift galaxies is a combination of their intrinsic emission and the effect of the Inter-Galactic medium (IGM) absorption along their line of sight. Using data coming from the unprecedented deep spectroscopy from the VANDELS ESO public survey carried out with the VIMOS instrument we compute both the dust extinction and the mean transmission of the IGM as well as its scatter from a set of 281 galaxies at z>3.87. Because of a degeneracy between the dust content of the galaxy and the IGM, we first estimate the stellar dust extinction parameter E(B-V) and study the result as a function of the dust prescription. Using these measurements as constraint for the spectral fit we estimate the IGM transmission Tr(Lyalpha). Both photometric and spectroscopic SED fitting are done using the SPectroscopy And photometRy fiTting tool for Astronomical aNalysis (SPARTAN) that is able to fit the spectral continuum of the galaxies as well as photometric data. Results. Using the classical Calzetti's attenuation law we find that E(B-V) goes from 0.11 at z=3.99 to 0.08 at z=5.15. These results are in very good agreement with previous measurements from the literature. We estimate the IGM transmission and find that the transmission is decreasing with increasing redshift from Tr(Lyalpha)=0.53 at z=3.99 to 0.28 at z=5.15. We also find a large standard deviation around the average transmission that is more than 0.1 at every redshift. Our results are in very good agreement with both previous measurements from AGN studies and with theoretical models.

description: Commercialization of agriculture in is a worthy effort in attaining food sufficiency in Africa. However, this needed quest has had an enormous environmental, health and safety implications for the agricultural sector of the continent. This quest has led to intense use of machinery, agrochemicals and other non-environmental friendly methods of farming. This implies there will be greater chances of farm accidents, mishap, fatality, production loss time and other burdens on farmer’s wellbeing on one hand and loss of biodiversity, environmental degradation, and unsustainable use of land all leading to climate change on the other hand. Holistically, due to the modus operandi of agricultural work, the workers are exposed to hazard ranging from; chemical, physical, ergonomics, biological and psychosocial hazards thereby leading to disorders and diseases like carcinogenicity (cancer causing), mutagenicity (induce mutations), tetragenicity (affect the feotus), psychiatric disorder and delayed neuropathy (dysfunction of peripheral nerves), and the dusts have been known to cause diseases ranging from byssinosis (lung diseases), occupational asthma, pneumonitis (inflammation o the walls of alveoli) and non-specific chronic obstructive pulmonary disease (COPD) and agriculturally related musculoskeletal disorder. Notwithstanding, a well implemented farm safety programme with massive awareness, more sustainable, environmental friendly method such as conservation agriculture and integration of environmental health impact assessments into African agriculture, research and development on commercialization of agriculture, are workable solutions to the likely health, safety and environmental challenges from the commercialization process.
Exploration of Balanced Metrics on Symmetric Positive Definite Matrices

description: Symmetric Positive Definite (SPD) matrices have been used in many fields of medical data analysis. Many Riemannian metrics have been defined on this manifold but the choice of the Riemannian structure lacks a set of principles that could lead one to choose properly the metric. This drives us to introduce the principle of balanced metrics that relate the affine-invariant metric with the Euclidean and inverse-Euclidean metric, or the Bogoliubov-Kubo-Mori metric with the Euclidean and log-Euclidean metrics. We introduce two new families of balanced metrics, the mixed-power-Euclidean and the mixed-power-affine metrics and we discuss the relation between this new principle of balanced metrics and the concept of dual connections in information geometry.
