description: Let $\mathbb{G}=\left(\mathbb{V},\mathbb{E}\right)$ be the graph obtained by taking the cartesian product of an infinite and connected graph $G=(V,E)$ and the set of integers $\mathbb{Z}$. We choose a collection $\mathcal{C}$ of finite connected subgraphs of $G$ and consider a model of Bernoulli bond percolation on $\mathbb{G}$ which assigns probability $q$ of being open to each edge whose projection onto $G$ lies in some subgraph of $\mathcal{C}$ and probability $p$ to every other edge. We show that the critical percolation threshold $p_{c}\left(q\right)$ is a continuous function in $\left(0,1\right)$, provided that the graphs in $\mathcal{C}$ are "well-spaced" in $G$ and their vertex sets have uniformly bounded cardinality. This generalizes a recent result due to Szabó and Valesin.
title: A Model of Housing Boom and Bust in a Small Open Economy
Creators: name: Tomura, Hajime
Publisher: name: Bank of Canada
Year: 2008

description: This paper considers a dynamic stochastic general equilibrium model for a small open economy and finds that an improvement in the terms of trade causes a housing boom-bust cycle if the duration of the improvement is uncertain. It is shown that as the economy has better access to the international financial market, the extent of the housing boom and bust gets larger. Also, an increase in the loan-to-value ratio in the domestic mortgage market tends to enhance the extent of the housing boom and bust when the economy has good access to the international financial market.
description: À l'aide d'un modèle d'équilibre général dynamique et stochastique qui décrit une petite économie ouverte, l'auteur montre qu'une amélioration des termes de l'échange provoque une flambée des prix du logement puis leur effondrement si la durée de cette amélioration est incertaine. Il constate qu'un meilleur accès de l'économie au marché financier international a pour effet d'accentuer l'ampleur du cycle des prix observé et que, lorsque l'économie a facilement accès à ce marché, une augmentation du ratio prêt-valeur sur le marché hypothécaire national tend à amplifier encore le cycle.

description: Lingafelteria Nearns and Tavakilian, gen. nov.
(Figures 2 a-d)
 Type species. Lingafelteria giuglarisi, sp. nov., here designated.
 Description. General form elongate-oblong, small to moderate-sized. Head with frons subquadrate, about 2.5 times width of one lower eye lobe. Eyes with lower lobes large, oblong. Genae transverse, distinctly shorter than lower eye lobes. Antennal tubercles prominent, widely separated; scape gradually expanded to apex; antennomeres III longest. Pronotum subcylindrical, transverse, sides arcuate; disk with feebly elevated tubercles. Scutellum transverse, apex rounded. Elytra attenuate to apices; humeri prominent. Legs moderate in length; femora robust; tibiae expanded apically; metafemora about 1/3 as long as elytra.
 Etymology. Lingafelteria is named for Steven Wayne Lingafelter, with appreciation for this friendship and collaboration. Steve has collected extensively in the Neotropics and has contributed greatly to our knowledge of cerambycid beetles. The gender is feminine.
 Diagnosis and Remarks. This genus closely resembles Proplerodia Martins and Galileo, 1990 but can be distinguished by the combination of the following characters: eyes with lower lobes distinctly taller than genae (lower lobes about as tall in P. goyana Martins and Galileo, 1990; slightly taller than gena in P. piriana Martins and Galileo, 2009); elytra without thin, longitudinal lines (elytra of P. piriana with 11 thin, longitudinal lines from base to apical 1/3; elytra of P. goyana with thin, longitudinal lines at apical half); and tarsomere V distinctly shorter than I-VI combined (about as long in Proplerodia).

description: Abdominal aortic aneurysm (AAA) is increasing due to aging of the population and is a major cause of death among the elderly. Ultrasound screening programs are useful in early diagnosis, but aneurysm size is not always a good predictor of rupture. Our aim was to analyze the value of circulating molecules related to oxidative stress and inflammation as new biomarkers to assist the management of AAA. The markers were quantified by ELISA, and their expression in the aneurysmal wall was studied by real-time PCR and by immunostaining. Correlation analysis of the studied markers with aneurysm diameter and peak wall stress (PWS), obtained by finite element analysis, and multivariate regression analysis to assess potential confounding factors were performed. Our study shows an extensive inflammatory infiltration in the aneurysmal wall, mainly composed by T-cells, macrophages and B-cells and altered levels of reactive oxygen species (ROS), IgM, IgG, CD38, GDF15, S100A4 and CD36 in plasma and in the aneurysmal tissue of AAA patients compared with controls. Circulating levels of IgG, CD38 and GDF15 positively correlated with abdominal aortic diameter, and CD38 was correlated with PWS. Our data show that altered levels of IgG, CD38 and GDF15 have potential diagnostic value in the assessment of AAA.

description: Abstract: Cancer cells upregulate anabolic processes to maintain high rates of cellular turnover. Limiting the supply of macromolecular precursors by targeting enzymes involved in biosynthesis is a promising strategy in cancer therapy. Several tumors excessively metabolize glutamine to generate precursors for nonessential amino acids, nucleotides, and lipids, in a process called glutaminolysis. Here we show that pharmacological inhibition of glutaminase (GLS) eradicates glioblastoma stem-like cells (GSCs), a small cell subpopulation in glioblastoma (GBM) responsible for therapy resistance and tumor recurrence. Treatment with small molecule inhibitors compound 968 and CB839 effectively diminished cell growth and in vitro clonogenicity of GSC neurosphere cultures. However, our pharmaco-metabolic studies revealed that only CB839 inhibited GLS enzymatic activity thereby limiting the influx of glutamine derivates into the TCA cycle. Nevertheless, the effects of both inhibitors were highly GLS specific, since treatment sensitivity markedly correlated with GLS protein expression. Strikingly, we found GLS overexpressed in in vitro GSC models as compared with neural stem cells (NSC). Moreover, our study demonstrates the usefulness of in vitro pharmaco-metabolomics to score target specificity of compounds thereby refining drug development and risk assessment.

description: The Taffy Galaxies system, UGC 12914/5, contains huge amounts of molecular gas in the bridge region between the receding spirals after a direct collision. $2 - 9 \times 10^9$M$_\odot$ of molecular gas is present between the galaxies, more than the CO emission from the entire Milky Way! Such dense gas can only be torn off by collisions between dense clouds, in this case with relative velocities of about 800 $\kms$, such that the remnant cloud acquires an intermediate velocity and is left in the bridge after separation of the colliding galaxies. We suggest that after ionization in the collision front, the gas cooled and recombined very quickly such that the density remained high and the gas left the colliding disks in molecular form.

Subjects: intergenerational contact, ageism, gamification

description: Background: Past research has found that positive intergenerational interactions can change young generation's negative attitudes towards the older generation. Among various types of intergenerational interactions, a gamified interaction, which consists of playing video-games together between two generations, has proved to be more effective. Research question: This research will specifically focus on three gamified interaction components: game design mechanism (competition vs. cooperation), player focus (process vs. outcome) and the game outcome (success vs. failure), and aim to explore whether and how gamified intergenerational interaction could change attitudes toward the older generation among younger generation.

description: In this paper, we investigate the holographic complexity in the charged Taub-NUT-AdS black holes with Misner strings present in the Einstein-Maxwell gravity. We show that differing from the normal black holes, where the late-time complexity growth rate is only determined by the quantities at outer and inner ``Reissner-Nordstrom''-type (RN-type) horizons, here the quantities (the Misner potential and Misner charge) related to the Misner strings also play an important role in CA complexity. Similar to the case of the normal electromagnetic black hole, the late-time rate for the original CA conjecture is independent on the magnetic charges. However, disparate with common results of the dyonic solutions, the electric charge appeared here is the total charge of this black hole. Besides, we found that the result in this original CA conjecture also violates the electromagnetic duality. And this duality can be restored by adding the Maxwell boundary term with the proportional constant $\g=1/2$. In this case, the late-time rate is sensitive to the magnetic charge. Moreover, we also found that the additional term only changes the proportion between the electric and magnetic charges, and it does not affect the Misner term appeared in the late-time rate. Finally, we studied the time-dependence of the complexity growth rate and found that they share similar behaviors with that in RN-AdS black holes.

description: We report a high-magnetic-field study of the itinerant ferromagnet URhSi. Magnetization and electrical resistivity were measured under magnetic fields $μ_0H$ up to 58~T applied along the directions $\mathbf{a}$, $\mathbf{b}$, and $\mathbf{c}$ of the orthorhombic structure and temperatures $T$ ranging from 1.5 to 50 K. For $\mathbf{H}\parallel\mathbf{b}$, pseudo-metamagnetism at $μ_0H_m\simeq30-40$~T is associated with a broad step in the magnetization and a maximum in the resistivity. The properties of URhSi are discussed and compared with those of the isostructural superconducting ferromagnets URhGe and UCoGe and of the superconducting paramagnet UTe$_2$.

description: We present a novel analysis extending the recent work of Mizuno et al. [2002] on the hyperinflations of Germany (1920/1/1-1923/11/1), Hungary (1945/4/30-1946/7/15), Brazil (1969-1994), Israel (1969-1985), Nicaragua (1969-1991), Peru (1969-1990) and Bolivia (1969-1985). On the basis of a generalization of Cagan's model of inflation based on the mechanism of ``inflationary expectation'' or positive feedbacks between realized growth rate and people's expected growth rate, we find that hyperinflations can be characterized by a power law singularity culminating at a critical time $t_c$. Mizuno et al.'s double-exponential function can be seen as a discrete time-step approximation of our more general nonlinear ODE formulation of the price dynamics which exhibits a finite-time singular behavior. This extension of Cagan's model, which makes natural the appearance of a critical time $t_c$, has the advantage of providing a well-defined end of the clearly unsustainable hyperinflation regime. We find an excellent and reliable agreement between theory and data for Germany, Hungary, Peru and Bolivia. For Brazil, Israel and Nicaragua, the super-exponential growth seems to be already contaminated significantly by the existence of a cross-over to a stationary regime.

description: The estimate of individual wave run-up is especially important for tsunami warning and risk assessment as it allows to evaluate the inundation area. Here as a model of tsunami we use the long single wave of positive polarity. The period of such wave is rather long which makes it different from the famous Korteweg-de Vries soliton. This wave nonlinearly deforms during its propagation in the ocean, what results in a steep wave front formation. Situations, when waves approach the coast with a steep front are often observed during large tsunamis, e.g. 2004 Indian Ocean and 2011 15 Tohoku tsunamis. Here we study the nonlinear deformation and run-up of long single waves of positive polarity in the conjoined water basin, which consists of the constant depth section and a plane beach. The work is performed numerically and analytically in the framework of the nonlinear shallow water theory. Analytically, wave propagation along the constant depth section and its run-up on a beach are considered independently without taking into account wave interaction with the toe of the bottom slope. The propagation along the bottom of constant depth is described by Riemann wave, while the wave 20 run-up on a plane beach is calculated using rigorous analytical solutions of the nonlinear shallow water theory following the Carrier-Greenspan approach. Numerically, we use the finite volume method with the second order UNO2 reconstruction in space and the third order Runge-Kutta scheme with locally adaptive time steps. During wave propagation along the constant depth section, the wave becomes asymmetric with a steep wave front. Shown, that the maximum run-up height depends on the front steepness of the incoming wave approaching the toe of the bottom slope. The corresponding formula for maximum 25 run-up height, which takes into account the wave front steepness, is proposed.

Creators: name: de Munnik, Daniel

description: A number of central banks publish their own business conditions survey based on non-random sampling methods. The results of these surveys influence monetary policy decisions and thus affect expectations in financial markets. To date, however, no one has computed the statistical accuracy of these surveys because their respective non-random sampling method renders this assessment non-trivial. This paper describes a methodology for modeling complex non-random sampling behaviour, and computing relevant measures of statistical confidence, based on a given survey's historical sample selection practice. We apply this framework to the Bank of Canada's Business Outlook Survey by describing the sampling method in terms of historical practices and Bayesian probabilities. This allows us to replicate the firm selection process using Monte Carlo simulations on a comprehensive micro-dataset of Canadian firms. We find, under certain assumptions, no evidence that the Bank's firm selection process results in biased estimates and/or wider confidence intervals.
description: Nombre de banques centrales publient leur propre enquête de conjoncture, qu'elles réalisent auprès d'entreprises sélectionnées de façon non aléatoire. Les résultats de leurs coups de sonde influencent les décisions de politique monétaire et, de ce fait, les attentes des marchés financiers. Jusqu'à présent, personne n'a mesuré la précision statistique de ces enquêtes, car il est difficile de l'évaluer en raison du mode d'échantillonnage non aléatoire. Les auteurs décrivent une méthodologie qui permet de modéliser des processus complexes d'échantillonnage non aléatoire et de calculer des indicateurs de confiance statistique pertinents sur la base du mode de sélection des entreprises utilisé pour une enquête donnée. Ils appliquent leur cadre méthodologique à l'enquête de la Banque du Canada sur les perspectives des entreprises en se fondant sur les pratiques suivies par le passé et les probabilités bayésiennes pour caractériser le mode d'échantillonnage. Les auteurs peuvent ainsi reproduire le processus de sélection des entreprises à l'aide d'une simulation de Monte-Carlo menée sur un riche ensemble de microdonnées constitué de firmes canadiennes. Sous certaines conditions, constatent-ils, le processus d'échantillonnage retenu par la Banque n'entraîne ni estimations biaisées ni intervalles de confiance élargis.

description: By the use of computer simulations we investigate, in the cellular automaton of two-dimensional traffic flow, the anisotropic effect of the probabilities of the change of the move directions of cars, from up to right ($p_{ur}$) and from right to up ($p_{ru}$), on the dynamical jamming transition and velocities under the periodic boundary conditions in one hand and the phase diagram under the open boundary conditions in the other hand. However, in the former case, the first order jamming transition disappears when the cars alter their directions of move ($p_{ur}\neq 0$ and/or $p_{ru}\neq 0$). In the open boundary conditions, it is found that the first order line transition between jamming and moving phases is curved. Hence, by increasing the anisotropy, the moving phase region expand as well as the contraction of the jamming phase one. Moreover, in the isotropic case, and when each car changes its direction of move every time steps ($p_{ru}=p_{ur}=1$), the transition from the jamming phase (or moving phase) to the maximal current one is of first order. Furthermore, the density profile decays, in the maximal current phase, with an exponent $γ\approx {1/4}$.}

description: Stellar magnetic activity decays over the main-sequence life of cool stars due to the stellar spin-down driven by magnetic braking. The evolution of chromospheric emission is well-studied for younger stars, but difficulties in determining the ages of older cool stars on the main sequence have complicated such studies for older stars in the past. Here we report on chromospheric Ca II H and K line measurements for 26 main-sequence cool stars with asteroseismic ages older than a gigayear and spectral types F and G. We find that for the G stars and the cooler F-type stars which still have convective envelopes the magnetic activity continues to decrease at stellar ages above one gigayear. Our magnetic activity measurements do not show evidence for a stalling of the magnetic braking mechanism, which has been reported for stellar rotation versus age for G and F type stars. We also find that the measured R'HK indicator value for the cool F stars in our sample is lower than predicted by common age-activity relations that are mainly calibrated on data from young stellar clusters. We conclude that, within individual spectral type bins, chromospheric magnetic activity correlates well with stellar age even for old stars.

description: Models with imperfect information that generate persistent monetary nonneutrality predominantly rely on assumptions leading to substantial heterogeneity of information across price-setters. This paper develops a quantitative general equilibrium model in which the degree of heterogeneity of information is determined endogenously. In the model, firms use two technologies to acquire information: costly updating to full information and costless learning from publicly observed market signals. Price changes of firms that update information infrequently are synchronized with market signals. This leads to an externality whereby less frequent updating increases the information conveyed by prices and quantities. When the model is calibrated to moments from a panel of BLS commodity sectors, it is found that the private value of costly updating to full information is close to zero, market signals are informative, and the real effects of monetary shocks are small.
description: Les modèles où l'information est imparfaite et où la monnaie n'est pas neutre en longue période reposent essentiellement sur des hypothèses qui introduisent une forte hétérogénéité dans l'information dont disposent les décideurs de prix. L'auteur construit un modèle d'équilibre général quantitatif dans lequel le degré d'hétérogénéité de l'information est déterminé de manière endogène. Les entreprises du modèle acquièrent de l'information par deux voies : au moyen d'une mise à jour qui leur donne accès à une information complète mais qui comporte un coût, et à la faveur d'une connaissance gratuite, déduite de signaux de marché de notoriété publique. Les entreprises qui actualisent peu fréquemment l'information modifient leurs prix au rythme des signaux du marché. Ce comportement donne lieu à une externalité du fait que la sporadicité des mises à jour accroît la quantité d'information véhiculée par les prix et les volumes. En étalonnant son modèle en fonction de moments calculés à partir des données du Bureau of Labor Statistics sur les prix d'une gamme étendue de produits, l'auteur constate que la mise à jour non gratuite est d'une valeur quasi nulle pour l'entreprise, que les signaux du marché apportent de l'information et que les chocs monétaires ont peu d'effets réels.

description: Substitutions in the Mn-sublattice of antiferromagnetic, charge and orbitally ordered manganites was recently found to produce intriguing metamagnetic transitions, consisting of a succession of sharp magnetization steps separated by plateaus. The compounds exhibiting such features can be divided in two categories, depending on whether they are sensitive to thermal cycling effects or not. One compound of each category has been considered in the present study. The paper reports on the influence of two treatments: high-temperature annealing and grinding. It is shown that both of these treatments can drastically affect the phenomenon of magnetization steps. These results provide us with new information about the origin of these jumps in magnetization.

description: We review generalized Fluctuation-Dissipation Relations which are valid under general conditions even in ``non-standard systems'', e.g. out of equilibrium and/or without a Hamiltonian structure. The response functions can be expressed in terms of suitable correlation functions computed in the unperperturbed dynamics. In these relations, typically one has nontrivial contributions due to the form of the stationary probability distribution; such terms take into account the interaction among the relevant degrees of freedom in the system. We illustrate the general formalism with some examples in non-standard cases, including driven granular media, systems with a multiscale structure, active matter and systems showing anomalous diffusion.

description: ${\rm SrRuO_3}$ is a 4d itinerant ferromagnet (T$_{c}$ $\sim $150 K) with stripe domain structure. Using high-quality thin films of SrRuO$_{3}$ we study the resistivity induced by its very narrow ($\sim 3$ nm) Bloch domain walls, $ρ_{DW}$ (DWR), at temperatures between 2 K and T$_{c}$ as a function of the angle, $θ$, between the electric current and the ferromagnetic domains walls. We find that $ρ_{DW}(T,θ)=\sin^2θρ_{DW}(T,90)+B(θ)ρ_{DW}(T,0)$ which provides the first experimental indication that the angular dependence of spin accumulation contribution to DWR is $\sin^2θ$. We expect magnetic multilayers to exhibit a similar behavior.

description: This paper investigates the impact of pyramid ownership structure and multiple controlling shareholders on firm leverage. Pyramids, having at least one controlling shareholder and a subsidiary, rely significantly more on debt financing than non-pyramid firms. Moreover, higher leverage is observed in pyramids where the second controlling shareholders have more voting rights. We also find that the disparity between the voting rights of the first two controlling shareholders is negatively related to firm leverage. Interestingly, the influence of the second controlling shareholder is only present in non-family controlled pyramids. Overall, the results are consistent with the view that controlling shareholders in pyramids use debt to secure their private benefits.
description: Les auteures étudient l'incidence de la structure de propriété pyramidale et de la présence de plusieurs actionnaires dominants sur le levier financier des sociétés. Les pyramides, qui comptent au moins un actionnaire dominant et une filiale, se financent beaucoup plus par emprunt que les autres types de société. Le recours au levier financier est encore plus marqué lorsque les deuxièmes actionnaires en importance ont davantage de droits de vote que les premiers. Les auteures constatent aussi que l'écart entre les droits de vote des deux principaux actionnaires est inversement lié au levier financier des sociétés. Fait intéressant, les deuxièmes actionnaires n'ont d'influence que dans les pyramides qui ne sont pas contrôlées par une famille. Dans l'ensemble, les résultats sont conformes au point de vue selon lequel les actionnaires dominants au sein des pyramides utilisent l'emprunt pour servir leurs intérêts privés.

description: The authors empirically analyze the price-setting behaviour of the major Canadian banks in the residential mortgage market over the period 1991–2007. They use weekly posted prices of the major mortgage providers to study the degree of competition in mortgage price setting. Their results suggest that the residential mortgage market is imperfectly competitive. They find distinct price leaders and that, as market concentration increases, so does price dispersion – helped by the increased use of discounting from posted prices. The authors also find that, although banks' pass-through of input price changes to mortgage prices is complete in the long run under reasonable assumptions regarding discounting, there exists some level of pricing asymmetry in the short run.
description: Les auteurs analysent empiriquement les pratiques des grandes banques canadiennes en ce qui concerne l'établissement des prix sur le marché des prêts hypothécaires à l'habitation au cours de la période 1991-2007. Pour évaluer le degré de concurrence dans la détermination de ces prix, ils utilisent les taux – publiés chaque semaine – des principaux prêteurs hypothécaires. Leurs résultats semblent indiquer que le marché des prêts hypothécaires à l'habitation est imparfaitement concurrentiel. Les auteurs observent une nette présence de chefs de file en matière de prix et notent que, à mesure que le marché devient plus concentré, la dispersion des prix augmente, favorisée par l'octroi accru de rabais par rapport aux taux publiés. Ils constatent également qu'il existe une certaine asymétrie dans l'établissement des prix à court terme même si, à long terme, les banques répercutent complètement les variations du prix des intrants sur leurs taux hypothécaires, selon des hypothèses raisonnables quant aux rabais consentis.

description: $γ$-CoV$_{2}$O$_{6}$ is a quasi one-dimensional spin-$\frac{3}{2}$ magnet that possesses two distinct magnetic orders in the ground state with modulation vectors $k_\mathrm{1}$ = ($\frac{1}{2}$, 0, 0) and $k_\mathrm{2}$ = ($\frac{1}{4}$, 0, -$\frac{1}{4}$), respectively. Here, we use muon spin relaxation and rotation to reveal the thermodynamics of the magnetic phase separation in this compound. In the paramagnetic (PM) region, short-range correlated spin clusters emerge at $T_\mathrm{m}$ $\simeq$ 26 K at the $\it{partial}$ expense of the PM volume. Upon further cooling, we show that these emergent clusters become spatially coherent at $T_\mathrm{N2}$ = 7.5 K and eventually form the $k_\mathrm{2}$ order at $T^{\star}$ = 5.6 K, while the remaining PM spins are driven into the $k_\mathrm{1}$ state at $T_\mathrm{N1}$ = 6.6 K. These results stress magnetic microphase inhomogeneity as a thermodynamic precursor for the ground state phase separation in weakly coupled spin-$\frac{3}{2}$ chains.

description: Weighted-sum energy efficiency (WSEE) is a key performance metric in heterogeneous networks, where the nodes may have different energy efficiency (EE) requirements. Nevertheless, WSEE maximization is a challenging problem due to its nonconvex sum-of-ratios form. Unlike previous work, this paper presents a systematic approach to WSEE maximization under not only power constraints, but also data rate constraints, using a general SINR expression. In particular, the original problem is transformed into an equivalent form, and then a sequential convex optimization (SCO) algorithm is proposed. This algorithm is theoretically guaranteed to converge for any initial feasible point, and, under suitable constraint qualifications, achieves a Karush-Kuhn-Tucker (KKT) solution. Furthermore, we provide remarkable extensions to the proposed methodology, including systems with multiple resource blocks as well as a more general power consumption model which is not necessarily a convex function of the transmit powers. Finally, numerical analysis reveals that the proposed algorithm exhibits fast convergence, low complexity, and robustness (insensitivity to initial points).

description: In the pursuit of sustainable methodologies in organic synthesis, the application of renewable and biodegradable catalysts has received significant attention. This work processes the synthesizing of 3,4-dihydropyrimidin-2(1H)-ones/thiones using L-arabinose, an environment-friendly catalyst via the Biginelli reaction in a solvent-free environment is reported herein. L-arabinose, a naturally occurring sugar, efficiently catalyzes the condensation reaction between β-ketoesters and aldehyde with urea or thiourea to form DHPMs with high yields and excellent atom economy. The reaction proceeds efficiently at mild temperatures, and the catalyst is easily regenerated, enabling multiple catalytic cycles. The use of L-arabinose avoids not only toxic solvents and metal catalysts but also processes green chemistry due to the exploitation of renewable resources. It is a significant step forward in the domain of sustainable catalysis and provides an environmentally benign and operationally simple procedure for the synthesis of DHPMs.

description: Obesity, especially visceral obesity, plays an important role in the progression of cardiovascular disease (CVD). The body roundness index (BRI) is a new measure of obesity that is considered to reflect visceral obesity more comprehensively than other measures. This study aims to evaluate the relationship between BRI and CVD risk in hypertensive patients with obstructive sleep apnea (OSA) and explore its superiority in predicting CVD. The Cox proportional hazards model was used to calculate the hazard ratios (HRs) and 95% confidence intervals (CIs) for incident CVD. The area under the curve (AUC), continuous net reclassification improvement (NRI), and integrated discrimination improvement (IDI) were used to assess which measures of obesity had the best predictive value for CVD risk. During a median follow-up period of 6.8 years, 324 participants suffered a CVD event. After multivariable adjustment, compared with the reference group (the first tertile), the HRs (95% CI) of CVD were 1.25 (95% CI, 0.93–1.70) and 1.74 (95% CI, 1.30–2.33) for subjects in the tertile 2 and tertile 3 groups, respectively. Compared with other measurement indicators, BRI has the highest predictive value for CVD risk [AUC: 0.627, 95% CI: 0.593–0.661]. The addition of the BRI to the fully adjusted multivariate model improved the predictive power for CVD, which was validated in the continuous NRI and the IDI (all P < .05). BRI was significantly associated with the risk of CVD in hypertensive patients with OSA. Furthermore, BRI may improve CVD risk prediction in hypertensive patients with OSA.
