title: The ‘Celtic Crisis’: Guarantees, Transparency and Systemic Liquidity Risk

Publisher: name: Bank of Canada
Year: 2013

description: Bank liability guarantee schemes have traditionally been viewed as costless measures to shore up investor confidence and prevent bank runs. However, as the experiences of some European countries, most notably Ireland, have demonstrated, the credibility and effectiveness of these guarantees are crucially intertwined with the sovereign’s funding risks. Employing methods from the literature on global games, we develop a simple model to explore the systemic linkage between the rollover risks of a bank and a government, which are connected through the government’s guarantee of bank liabilities. We show the existence and uniqueness of the joint equilibrium and derive its comparative static properties. In solving for the optimal guarantee numerically, we show how its credibility can be improved through policies that promote balance-sheet transparency. We explain the asymmetry in risk transfer between the sovereign and the banking sector, following the introduction of a guarantee as being attributed to the resolution of strategic uncertainties held by bank depositors and the opacity of the banks’ balance sheets.
description: Les programmes de garantie des passifs bancaires ont traditionnellement été perçus comme des moyens, à coût nul, de soutenir la confiance des investisseurs et de prévenir les retraits massifs de dépôts. Toutefois, comme en témoigne l’expérience de certains pays européens, surtout l’Irlande, la crédibilité et l’efficacité de ces programmes et le risque de financement souverain sont imbriqués de façon cruciale. À l’aide de méthodes inspirées de la littérature sur les jeux globaux, les auteurs élaborent un modèle simple qui permet d’explorer le lien systémique que la garantie de l’État sur les passifs bancaires crée entre le risque de refinancement d’une banque et le risque de financement souverain. Les auteurs démontrent l’existence et l’unicité de l’équilibre conjoint et en établissent les propriétés de statique comparative. En déterminant numériquement le niveau de garantie optimal, ils montrent que l’adoption de politiques favorisant la transparence des bilans peut accroître la crédibilité de la garantie offerte. Enfin, ils expliquent l’asymétrie du transfert du risque entre le secteur bancaire et l’État, après la mise en place d’un programme de garantie, par la levée de l’incertitude stratégique à laquelle sont confrontés les déposants et par l’opacité des bilans bancaires.

description: A survey of 30 nearby M6.0-M7.5 dwarfs with Ks<12 mag utilizing the Hokupa'a adaptive optics system at the Gemini North Telescope has discovered 3 new binary systems. All 3 systems have separations between 0.12-0.29 arcsec (3-10 AU) with similar mass ratios (q>0.8, Delta Ks<0.7). This result gives further support to the suggestion that wide (a>20 AU) very low mass (M_{tot}<0.185 M_sun) binary systems are exceedingly rare or perhaps even non-existant. The semimajor axis distribution of these systems peaks at ~5 AU, tighter than more massive M and G binary distributions which have a broad peak at separations of \~30 AU. We find a sensitivity-corrected binary fraction in the range of 5_{-2}^{+4}% for M6.0-M7.5 stars with separations a>3 AU. This binary frequency is less than the ~32% measured among early M dwarfs over the same separation range. Two of the low-mass binaries are probable Hyades open cluster members based on proper motions, cluster membership probabilities, radial velocities, and near-IR photometry. LP415-20 has the distinction of being the tightest (3.6 AU) multiple system ever spatially resolved in the cluster and the companions of LP415-20 and LP475-855 are among the least massive objects ever resolved in the Hyades with estimated masses of 0.081_{-0.010}^{+0.009} and 0.082_{-0.009}^{+0.009} M_{\sun}.

description: Online palmprint recognition and latent palmprint identification are two branches of palmprint studies. The former uses middle-resolution images collected by a digital camera in a well-controlled or contact-based environment with user cooperation for commercial applications and the latter uses high-resolution latent palmprints collected in crime scenes for forensic investigation. However, these two branches do not cover some palmprint images which have the potential for forensic investigation. Due to the prevalence of smartphone and consumer camera, more evidence is in the form of digital images taken in uncontrolled and uncooperative environment, e.g., child pornographic images and terrorist images, where the criminals commonly hide or cover their face. However, their palms can be observable. To study palmprint identification on images collected in uncontrolled and uncooperative environment, a new palmprint database is established and an end-to-end deep learning algorithm is proposed. The new database named NTU Palmprints from the Internet (NTU-PI-v1) contains 7881 images from 2035 palms collected from the Internet. The proposed algorithm consists of an alignment network and a feature extraction network and is end-to-end trainable. The proposed algorithm is compared with the state-of-the-art online palmprint recognition methods and evaluated on three public contactless palmprint databases, IITD, CASIA, and PolyU and two new databases, NTU-PI-v1 and NTU contactless palmprint database. The experimental results showed that the proposed algorithm outperforms the existing palmprint recognition methods.

description: We compute the probability distribution of the interface width at the depinning threshold, using recent powerful algorithms. It confirms the universality classes found previously. In all cases, the distribution is surprisingly well approximated by a generalized Gaussian theory of independant modes which decay with a characteristic propagator G(q)=1/q^(d+2 zeta); zeta, the roughness exponent, is computed independently. A functional renormalization analysis explains this result and allows to compute the small deviations, i.e. a universal kurtosis ratio, in agreement with numerics. We stress the importance of the Gaussian theory to interpret numerical data and experiments.

Cable-stayed glass façades - 15 years of innovation at the cutting edge

Publisher: name: Challenging Glass Conference Proceedings

description: Today’s demand for highly transparent building envelopes calls for innovative solutions. Cable-stayed glass façades make it possible to dematerialize the building envelope so as to make it almost imperceptible. Werner Sobek has designed a great number and variety of cable-stayed façades. The primary structural system carrying most of these façades consists of straight tension members (e.g. tension rods, cables), typically in a parallel arrangement. The tension members transfer the dead load of the glazing very efficiently to the supports. Under wind load the members undergo large deflections thus activating their lateral stiffness. As a result, the detailing of these façades requires innovative design approaches and special care to allow for such large deflections. Besides this, each project has its individual challenges such as a complex geometry, large openings, difficult edge conditions, warping of IG units, bomb blast requirements, etc. The present article gives an overview of the development of cable-stayed façades as designed by Werner Sobek over the last 15 years. The overview includes completed projects as well as façades currently under construction or in the design phase.

description: We present a celestial reference frame (CRF) from Very Long Baseline Interferometry (VLBI) Global Observing System (VGOS) including data until December 2024. The VGOS CRF is built with 1.8 million group delays observed in 193 multi-baseline 24-hour sessions (178 VGOS-OPS, 15 VGOS-R&D) with a fixed frequency distribution. It includes 418 radio sources, where 271 sources were observed in VGOS-OPS and 459 sources in VGOS-R&D. We show that VGOS-R&D scheduled with the source-centric method are beneficial for generating the VGOS CRF and at the same time they have been proven to provide high quality geodetic parameters. Comparison with ICRF3-SX reveals that 21% sources have normalized angular separation higher than 5 times the formal error. The VIE2024-VG CRF solution has excellent formal source position precision: median formal precision is 25 microas in right ascension and 41 microas in declination.

description: This paper reports a series of pre-trade investigations into the hedge effectiveness of futures contracts of wheat, barley, and canola for Western Australia hedgers. Hedge ratios were estimated through the ordinary least square model, the vector autoregressive model, and the vector error-correction model. Hedging effectiveness was measured using risk reduction method and utility maximization method. Results indicate that, despite being thinly traded contracts, futures on Australia Securities Exchange are more effective in wheat, barley, and canola in terms of price risks minimization and utility maximization, comparing with futures contracts on Chicago Board of Trade and Intercontinental Exchange. Results suggest that using the local exchange is more efficient in risk management.

description: Current architecture uses glass even for load bearing structural elements. Typical example is perpendicularly loaded laminated glass panel as a part of balustrade, staircase, or canopy. Laminated glass is a composition of two or more glass plies bonded by polymeric interlayer which enables the shear transfer between the individual plies in a laminated panel. The shear transfer depends on the shear stiffness of a certain interlayer as a time and temperature dependent parameter. Shear stiffness in time and temperature domain can be numerically described by a discrete Maxwell model whose Prony parameters may be obtained by Dynamic mechanical thermal analysis (DMTA) of a particular interlayer. There are various techniques of DMTA as well as various Prony parameters fitting methods. As soon as shear stiffness given by Maxwell model is quantified, it is desirable to verify its credibility by experiment. This paper compares the experimental data from displacement-controlled four-point bending tests in various loading rates and from four point bending longterm creep experiment of double laminated glass panels with PVB interlayer Trosifol BG-R20® to the numerical analysis performed in ANSYS® 18.0. The interlayer was modelled as a viscoelastic material by two discrete Maxwell models. Prony parameters of the first Maxwell model were based on DMTA results performed on small scale specimens in single lap shear mode and Prony parameters of the second Maxwell model were based on DMTA results performed on small scale specimens in single lap shear mode and torsion mode. Results show that Maxwell model based only on single lap shear tests enabled to describe the long-term response of a panel while that based on single lap shear and torsion tests was more precise in task of displacement-controlled test. All experiments and analyses were performed at CTU in Prague.

Higher correlations, universal distributions and finite size scaling in the field theory of depinning

Year: 2003
Subjects: subject: Condensed Matter (cond-mat)

description: Recently we constructed a renormalizable field theory up to two loops for the quasi-static depinning of elastic manifolds in a disordered environment. Here we explore further properties of the theory. We show how higher correlation functions of the displacement field can be computed. Drastic simplifications occur, unveiling much simpler diagrammatic rules than anticipated. This is applied to the universal scaled width-distribution. The expansion in d=4-epsilon predicts that the scaled distribution coincides to the lowest orders with the one for a Gaussian theory with propagator G(q)=1/q^(d+2 ζ), zeta being the roughness exponent. The deviations from this Gaussian result are small and involve higher correlation functions, which are computed here for different boundary conditions. Other universal quantities are defined and evaluated: We perform a general analysis of the stability of the fixed point. We find that the correction-to-scaling exponent is omega=-epsilon and not -epsilon/3 as used in the analysis of some simulations. A more detailed study of the upper critical dimension is given, where the roughness of interfaces grows as a power of a logarithm instead of a pure power.

description: We compute rates of tidal disruption of stars by supermassive black holes in galactic nuclei, using downwardly-revised black hole masses from the M-sigma relation. In galaxies with steep nuclear density profiles, which dominate the overall event rate, the disruption frequency varies inversely with assumed black hole mass. We compute a total rate for non-dwarf galaxies that is about a factor ten higher than in earlier studies. Disruption rates are predicted to be highest in nucleated dwarf galaxies, assuming that such galaxies contain black holes. Monitoring of a rich galaxy cluster for a few years could rule out the existence of intermediate mass black holes in dwarf galaxies.

On Richtmyer-Meshkov unstable dynamics of three-dimensional interfacial coherent structures with time-dependent acceleration
Creators: name: Hill, Desmond

Publisher: name: arXiv
Year: 2019
Subjects: subject: Fluid Dynamics (physics.flu-dyn)

description: Richtmyer-Meshkov instability (RMI) plays an important role in many areas of science and engineering, from supernovae and fusion to scramjets and nano-fabrication. Classical Richtmyer-Meshkov instability is induced by a steady shock and impulsive acceleration, whereas in realistic environments the acceleration is usually variable. We focus on RMI induced by acceleration with power-law time-dependence and apply group theory to solve the long-standing problem. For early-time dynamics, we find the dependence of the growth-rate on the initial conditions and show that it is independent of the acceleration parameters. For late-time dynamics, we find a continuous family of regular asymptotic solutions, including their curvature, velocity, Fourier amplitudes, and interfacial shear, and we study their stability. For each solution, the interface dynamics is directly linked to the interfacial shear, the non-equilibrium velocity field has intense fluid motion near the interface and effectively no motion in the bulk. The quasi-invariance of the fastest stable solution suggests that nonlinear coherent dynamics in RMI is characterized by two macroscopic length-scales -- the wavelength and the amplitude, in agreement with observations. The properties of a number of special solutions are outlined, these being respectively, the Atwood, Taylor, convergence, minimum-shear, and critical bubbles, among others. We also elaborate new theory benchmarks for future experiments and simulations.

description: We report x-ray scattering studies of nanoscale structural correlations in the paramagnetic phases of the perovskite manganites La$_{0.75}$(Ca$_{0.45}$Sr$_{0.55}$)$_{0.25}$MnO$_3$, La$_{0.625}$Sr$_{0.375}$MnO$_3$, and Nd$_{0.45}$Sr$_{0.55}$MnO$_3$. We find that these correlations are present in the orthorhombic $O$ phase in La$_{0.75}$(Ca$_{0.45}$Sr$_{0.55}$)$_{0.25}$MnO$_3$, but they disappear abruptly at the orthorhombic-to-rhombohedral transition in this compound. The orthorhombic phase exhibits increased electrical resistivity and reduced ferromagnetic coupling, in agreement with the association of the nanoscale correlations with insulating regions. In contrast, the correlations were not detected in the two other compounds, which exhibit rhombohedral and tetragonal phases. Based on these results, as well as on previously published work, we propose that the local structure of the paramagnetic phase correlates strongly with the average lattice symmetry, and that the nanoscale correlations are an important factor distinguishing the insulating and the metallic phases in these compounds.

Keogh grew up in the 1990s, “when the videogame console sat next to the VHS player” (5). For him, the ostensible normalcy of videogames raised some scepticism about how radically different that “new” medium really was from other “old” media. This scepticism prompted his initial question: how do videogames make meaning?

Demand and Price Analysis

description: The Capper-Volstead Act, passed in 1922, is the magna carta of agricultural cooperatives. The act has two sections. The first section generally defines what a Capper-Volstead cooperative is and the second section prohibits under price enhancement. Congress clearly intended that farmers be able to organize cooperatives and capture a share of market sufficient to raise price. However, Congress did not want to allow cooperatives with large market shares to unduly enhance the prices in the market channel. The basic question is what impact on price does a particular agricultural cooperative have? If in face an agricultural cooperative can raise farmgate prices, as indeed Congress hoped, is the resulting price elevation undue price enhancement?

description: When it comes to advertising, food processors out-spend every other sector of the economy. However, farmer-owned cooperatives seem less enamored of the powers of Madison Avenue than their privately owned counterparts in the food industry. Advertising data spanning a 20-year period, from 1967 to 1987, show that agricultural cooperatives spent proportionately less to advertise their brand-name products (based on their share of food dollars) than did non-cooperative food processors. The data also indicate that cooperatives' share of branded advertising expenditures has remained unchanged during the 20-year period examined for this study.

description: From density functional theory investigations helped with crystal chemistry rationale, single-atom C, embedded in layered hexagonal CCn with n = 6, 12, 18 networks, is stable in a magnetic state with M(C)= 2 Bohr Magneton (BM). The examined compositions, all inscribed within the P6/mmm 191 space group are characterized as increasingly cohesive with n, figuring mono, bi and tri layered honeycomb-like C networks respectively. The spin projected total density of states shows a closely half-metallic behavior with a gap at minority spins and metallic majority spins. Such results together with the large C-C intersite separation and the integer 2 BM magnetization, let propose an intra-band mechanism of magnetic moment onset on carbon 2p states. Support is provided from complementary calculations assuming C2C12 structure with planar 2 C with d(C-C)= 2.46 Angstroms resulting into a lowering of the magnetization down to 0.985 BM per C atom involving a ferromagnetic order arising from interband spin polarization on C where one nonbonding spin polarizes whereas the other is involved with the bonding with the other carbon. Further illustrative proofs are provided with the magnetic charge density projected onto the different atoms, showing its prevalence around C, contrary to the C6 layers, as well as electron localization function ELF.

description: We present full stellar evolution and parametric models of the surface abundance evolution of O16, Ne22, Na23 and the magnesium isotopes in an extremely metal-poor intermediate mass star M_ZAMS=5M_sun, Z=0.0001. O16 and Ne22 are injected into the envelope by the third dredge-up following thermal pulses on the asymptotic giant branch. These species and the initially present Mg24 are depleted by hot bottom burning (HBB) during the interpulse phase. As a result, Na23, Mg25 and Mg26 are enhanced. If the HBB temperatures are sufficiently high for this process to deplete oxygen efficiently, Na23 is first produced and then depleted during the interpulse phase. Although the simultaneous depletion of O16 and enhancement of Na23 is possible, the required fine tuning of the dredge-up and HBB casts some doubt on the robustness of this process as the origin of the O-Na anti-correlation observed in globular cluster stars. However, a very robust prediction of our models are low Mg24/Mg25 and Mg24/Mg26 ratios whenever significant O16 depletion can be achieved. This seems to be in stark contrast with recent observations of the magnesium isotopic ratios in the globular cluster NGC6752.

description: We have measured the current-voltage (I-V) characteristics of small-capacitance single Josephson junctions at low temperatures (T=0.02-0.6 K), where the strength of the coupling between the single junction and the electromagnetic environment was controlled with one-dimensional arrays of dc SQUIDs. The single-junction I-V curve is sensitive to the impedance of the environment, which can be tuned IN SITU. We have observed Coulomb blockade of Cooper-pair tunneling and even a region of negative differential resistance, when the zero-bias resistance R_0' of the SQUID arrays is much higher than the quantum resistance R_K = h/e^2 = 26 kohm. The negative differential resistance is evidence of coherent single-Cooper-pair tunneling within the theory of current-biased single Josephson junctions. Based on the theory, we have calculated the I-V curves numerically in order to compare with the experimental ones at R_0' >> R_K. The numerical calculation agrees with the experiments qualitatively. We also discuss the R_0' dependence of the single-Josephson-junction I-V curve in terms of the superconductor-insulator transition driven by changing the coupling to the environment.

Moderators were sample characteristics (i.e., age, cleft type, publication year, and study location) and measurement characteristics (i.e., speech sample material, language modality and domain, and assessment type).Results: Young children with NSCL/P scored significantly lower on measures of speech and language compared to children without NSCL/P. Children with NSCL/P had smaller consonant inventories (standardized mean difference effect size [ESg] = −1.24), less accurate articulation (ESg = −1.13), and more speech errors (ESg = 0.93) than their peers. Additionally, children with NSCL/P had poorer expressive (ESg = −0.57) and receptive (ESg = −0.59) language skills than their peers. Age and assessment type moderated effect sizes for expressive language. As children with NSCL/P aged, their expressive language performance became more similar to their peers. Expressive language effect sizes from parent reports and observational language measures (estimated effect size = −0.74) were significantly lower than those from standardized norm-referenced tests (estimated effect size = −0.45).Conclusions: These findings suggest that young children with NSCL/P experience delays relative to their peers across multiple speech and language constructs. Differences between children with NSCL/P and their typically developing peers appear to decrease with age.

description: This paper addresses an existing gap in the developing literature on conditional skewness. We develop a simple procedure to evaluate parametric conditional skewness models. This procedure is based on regressing the realized skewness measures on model-implied conditional skewness values. We find that an asymmetric GARCH-type specification on shape parameters with a skewed generalized error distribution provides the best in-sample fit for the data, as well as reasonable predictions of the realized skewness measure. Our empirical findings imply significant asymmetry with respect to positive and negative news in both conditional asymmetry and kurtosis processes.
description: Les auteurs élaborent une procédure d’évaluation simple des modèles paramétriques d’asymétrie conditionnelle en vue de combler une lacune de la littérature sur le sujet. Cette procédure est basée sur la régression de l’asymétrie réalisée sur l’asymétrie conditionnelle. Les auteurs constatent qu’une spécification de type GARCH-asymétrique pour les paramètres de forme, couplée à une distribution d’erreurs généralisée asymétrique, offre le meilleur ajustement statistique en échantillon ainsi qu’une prévisibilité satisfaisante de la mesure de l’asymétrie réalisée. Ils notent une importante asymétrie dans l’effet des bonnes et des mauvaises nouvelles sur le plan tant de la dynamique de l’asymétrie conditionnelle que de celle de l’aplatissement conditionnel.

description: The article assesses legal regulations regarding managing agricultural lands in Poland. The paper presents, first of all, the scope of activity of the Agricultural Property Agency, which is a significant institution on the property market. This institution started its activity on 1 January 1992 and its main task was to take over all state agricultural property and to manage the property in compliance with the regulations. Secondly, the article analyzes basic regulations concerning the sale and lease. They both give legal title to organize family as well as large farms. It also presents information about perpetual usufruct. Additionally, the article shows the EU instruments which have an essential impact on changing the agricultural structure, namely structural pensions and bonuses for young farmers.

description: In the article we describe an enhancement to the Demand for Labour (DL) survey conducted by Statistics Poland, which involves the inclusion of skills obtained from online job advertisements. The main goal is to provide estimates of the demand for skills (competences), which is missing in the DL survey. To achieve this, we apply a data integration approach combining traditional calibration with the LASSO-assisted approach to correct representation error in the online data. Faced with the lack of access to unit-level data from the DL survey, we use estimated population totals and propose a~bootstrap approach that accounts for the uncertainty of totals reported by Statistics Poland. We show that the calibration estimator assisted with LASSO outperforms traditional calibration in terms of standard errors and reduces representation bias in skills observed in online job ads. Our empirical results show that online data significantly overestimate interpersonal, managerial and self-organization skills while underestimating technical and physical skills. This is mainly due to the under-representation of occupations categorised as Craft and Related Trades Workers and Plant and Machine Operators and Assemblers.
Unstable Cold Dark Matter and the Cuspy Halo Problem in Dwarf Galaxies

description: We speculate that the dark halos of dwarf galaxies and low surface brightness galaxies soften their central cusps by the decay of a fraction of cold dark matter (CDM) particles to a stable particle with a recoiling velocity of a few tens km s$^{-1}$, after they have driven the formation of galactic halos. This process, however, does not necessarily produce a significant reduction of the central dark matter density of satellite dwarf spheroidals like Draco or Fornax. It is shown that the recovered distribution of concentration parameters $c$ for the initial (before decay) Navarro-Frenk-White halos, is in good agreement with CDM predictions. Other interesting potentials of unstable CDM are highlighted.

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

description: We have developed a parallel algorithm that allows us to enumerate the number of self-avoiding polygons on the square lattice to perimeter length 110. We have also extended the series for the first 10 area-weighted moments and the radius of gyration to 100. Analysis of the resulting series yields very accurate estimates of the connective constant $μ=2.63815853031(3)$ (biased) and the critical exponent $α= 0.5000001(2)$ (unbiased). In addition we obtain very accurate estimates for the leading amplitudes confirming to a high degree of accuracy various predictions for universal amplitude combinations.

description: This paper explores two alternative mould fabrication technologies that allow for the casting of (solid) glass components with a great degree of freedom in shape and size and/or of a customized design, in a cost-efficient way. In specific, the paper discusses the research, design and experimental work conducted at TU Delft on 3D-printed sand moulds and adjustable, high-precision steel moulds. 3D-printed sand moulds can provide a high-accuracy, cost-effective solution for solid glass components of complex geometry and/or of customized design. Although this mould technique is already used for metal castings, it remains still unexplored in the field of glass casting. Accordingly, this paper presents the first experimental findings at TU Delft of this mould technology: mould samples using different binders and treated with various coatings for surface finishing are tested in the high temperatures anticipated in glass (kiln-)casting. Following, 3D-printed moulds are prepared for a given glass geometry and physical glass prototypes are made by kiln-casting. Adjustable metal moulds are another mould technique that offers a degree of freedom in the modulus of a structure. Essentially, components of different sizes and, to an extent, shapes can be generated by the same mould. Accordingly, the design principles and engineering of such a mould and the potential applications and limitations of this technology are discussed. As a proof of concept, an adjustable mould is made using 3D-printed PLA and laser-cut MDF. The mould is used for the generation of wax models of variable forms, which are used to kiln-cast glass prototypes by the lost-wax technique. Based on the findings on both presented mould technologies, guidelines are given on their suitability according to the production volume, the level of accuracy required and the complexity and variation of forms involved.

description: The Cassini/Composite InfraRed Spectrometer (CIRS) instrument has been observing the middle atmosphere of Titan over almost half a Saturnian year. We used the CIRS dataset processed through the up-to-date calibration pipeline to characterize seasonal changes of temperature and abundance profiles in the middle atmosphere of Titan, from mid-northern winter to early northern summer all around the satellite. We used limb spectra from 590 to 1500 cm$^{-1}$ at 0.5-cm$^{-1}$ spectral resolution, which allows us to probe different altitudes. We averaged the limb spectra recorded during each flyby on a fixed altitude grid to increase the signal-to-noise ratio. These thermal infrared data were analyzed by means of a radiative transfer code coupled with an inversion algorithm, in order to retrieve vertical temperature and abundance profiles. These profiles cover an altitude range of approximately 100 to 600 km, at 10- or 40-km vertical resolution (depending on the observation). Strong changes in temperature and composition occur in both polar regions where a vortex is in place during the winter. At this season, we observe a global enrichment in photochemical compounds in the mesosphere and stratosphere and a hot stratopause located around 0.01 mbar, both linked to downwelling in a pole-to-pole circulation cell. After the northern spring equinox, between December 2009 and April 2010, a stronger enhancement of photochemical compounds occurred at the north pole above the 0.01-mbar region, likely due to combined photochemical and dynamical effects. During the southern autumn in 2015, above the South pole, we also observed a strong enrichment in photochemical compounds that contributed to the cooling of the stratosphere above 0.2 mbar. Close to the northern spring equinox, in December 2009, the thermal profile at 74°N exhibits an oscillation that we interpret in terms of an inertia-gravity wave.
