title:  Tra Edipo ed Antigone. Archeologia del soggetto e apertura narrativa del sé secondo Paul Ricœur
Creators: name: Casucci  ,  Marco
Publisher: name: Roma TrE-Press
Year: 2021

description: Il saggio si propone di indagare l’evoluzione del simbolo tragico nel pensiero di Ricœur tra Edipo e Antigone. La prevalenza dell’Edipo tiranno, in particolare nel primo periodo della riflessione ricœuriana, orientata verso una critica dell’interpretazione freudiana, è bilanciata da una riscoperta del “tragico dell’azione” di Antigone come è ben esposto nell’Interludio di Sé stesso come Altro. D’altra parte, nell’ultima opera di Ricœur, Il corso del riconoscimento, la figura di Edipo, così come è narrata nell’ultima tragedia sofoclea, l’Edipo Colono, risorge come prototipo del riconoscimento di sé. Così, le figure tragiche di Edipo e Antigone sono vissute dal pensiero ricœuriano in tempi e a livelli diversi, riflettendo la sua evoluzione attraverso le diverse età di Ricœur stesso, mostrando la connessione tra il tema della tragedia e la dimensione narrativa del sé.

description: The dynamics of supercooled liquid and glassy systems are usually studied within the Lagrangian representation, in which the positions and velocities of distinguishable interacting particles are followed. Within this representation, however, it is difficult to define measures of spatial heterogeneities in the dynamics, as particles move in and out of any one given region within long enough times. It is also non-transparent how to make connections between the structural glass and the spin glass problems within the Lagrangian formulation. We propose an Eulerian formulation of supercooled liquids and glasses that allows for a simple connection between particle and spin systems, and that permits the study of dynamical heterogeneities within a fixed frame of reference similar to the one used for spin glasses. We apply this framework to the study of the dynamics of colloidal particle suspensions for packing fractions corresponding to the supercooled and glassy regimes, which are probed via confocal microscopy.

Trapped region in Kerr-Vaidya space-time

description: We review the basic definitions and properties of trapped surfaces and discuss them in the context of Kerr-Vaidya line-element. Our study shows that the apparent horizon does not exist in general for axisymmetric space-times. The reason being the surface at which the null tangent vectors are geodesic and the surface at which the expansion of such vectors vanishes do not coincide. Calculation of an approximate apparent horizon for space-times that ensure its existence seems to be the only way to get away with this problem. The approximate apparent horizon, however, turned out to be non-unique. The choice of the shear free null geodesics, at least in the leading order, seem to remove this non-uniqueness. We also propose a new definition of the black hole boundary.

THE LONG HISTORY OF THE URBAN CENTRE AND THE TERRITORY OF POZZUOLI PORT CITY THROUGH NATURAL CATASTROPHES AND ITS EXTRAORDINARY RESILIENCE
Creators: name: Colletta, Teresa

Year: 2018

description: Taking into account the results of a previous research of the Mediterranean port-towns in the South of Italy, and some studies on the earthquakes of November 1980 and June 2009, and their effects on the historical centres (destruction and reconstruction in situ), the paper presents a rare example of the long-lasting resilience that enabled a port city to react to a long series of disasters and rebuildings: Pozzuoli in the Campania Region (Italy). The aim of the paper is to connect and combine in the urban history of Pozzuoli two strands of historical analysis: Mediterranean port city research and disaster and resilience studies. In this perspective, the paper examines the long sequence of terrible disasters from antiquity to contemporary age and stress that, from the day immediately following them, there has been a continuity of life and even an improvement of economic activities. The attention is given to three major disasters and the rebuilding and reconstruction of port and infrastructures, by means of iconographic and cartographic sources. Keywords: port city, disasters, resilience

Using long-term transit timing to detect terrestrial planets

Year: 2006
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We propose that the presence of additional planets in extrasolar planetary systems can be detected by long-term transit timing studies. If a transiting planet is on an eccentric orbit then the presence of another planet causes a secular advance of the transiting planet's pericenter over and above the effect of general relativity. Although this secular effect is impractical to detect over a small number of orbits, it causes long-term differences in when future transits occur, much like the long-term decay observed in pulsars. Measuring this transit-timing delay would thus allow the detection of either one or more additional planets in the system or the first measurements of non-zero oblateness ($J_2$) of the central stars.

description: We study the single-plane-wave Larkin-Ovchinnikov-Fulde-Ferrell (LOFF) states for BCS--Bose-Einstein condensation (BEC) crossover at general temperatures $T$. Because we include the important effects of noncondensed pairs, our $T \neq 0$ phase diagrams are different from those reported in earlier work. We find that generalized LOFF phases may be the ground state for a wide range of (weak through moderately strong) interactions, including the unitary regime. However, these LOFF phases are readily destroyed by non-zero $T$.

description: Il rito di accesso a un luogo è spesso la chiave che consente di penetrare i segreti originari e la vita conflittuale delle architetture o anche di intere città. A Pausilypon sono diversi i riti di accesso che nei secoli si sono succeduti nella fruizione di questo luogo straordinario. Il mare, il lungo antro ipogeo, i sentieri discendenti dalla collina rivelano le diverse “visioniˮ culturali e costruttive del rapporto tra architettura e forme naturali che in questi luoghi si sono avvicendate nel tempo. Nella storia di Capo Posillipo, tra le due Guerre, si sono aggiunti, a monte e al lato della Villa Imperiale, due esemplari interventi architettonici: il Parco della Bellezza (oggi Parco Virgiliano) e il poco noto Asilo degli “Scugnizziˮ a Marechiaro (oggi Centro San Francesco), un capitolo illuminato di Medicina e Architettura sociale che si propose a livello internazionale come modello laico, formativo e di integrazione all’avanguardia. Da questi due capisaldi “moderniˮ parte lo studio progettuale per delineare un più ampio sistema di fruizione del parco archeologico e del mare.

description: Both the long-duration gamma-ray bursts (LGRBs) and the Type I superluminous supernovae (SLSNe~I) have been proposed to be primarily powered by central magnetars. A correlation, proposed between the initial spin period ($P_0$) and the surface magnetic field ($B$) of the magnetars powering the X-ray plateaus in LGRB afterglows, indicates a possibility that the magnetars have reached an equilibrium spin period due to the fallback accretion. The corresponding accretion rates are inferred as $\dot{M}\approx10^{-4}-10^{-1}$ M$_\odot$ s$^{-1}$, and this result holds for the cases of both isotropic and collimated magnetar wind. For the SLSNe~I and a fraction of engine-powered normal type Ic supernovae (SNe~Ic) and broad-lined subclass (SNe~Ic-BL), the magnetars could also reach an accretion-induced spin equilibrium, but the corresponding $B-P_0$ distribution suggests a different accretion rate range, i.e., $\dot{M}\approx 10^{-7}-10^{-3}$ M$_\odot$ s$^{-1}$. Considering the effect of fallback accretion, magnetars with relatively weak fields are responsible for the SLSNe~I, while those with stronger magnetic fields could lead to SNe~Ic/Ic-BL. Some SLSNe~I in our sample could arise from compact progenitor stars, while others that require longer-term accretion may originate from the progenitor stars with more extended envelopes or circumstellar medium.

description: The space gravitational wave (GW) detector Laser Interferometer Space Antenna (LISA) that was planed to launch in the early 2030s is to detect the low-frequency GW signals in the Galaxy. AM CVn stars were generally thought to be important low-frequency GW sources. Employing the MESA code, in this work we calculate the evolution of a great number of binary systems consisting of a white dwarf (WD) and a main sequence (MS) star, and diagnose whether their descendants-AM CVn stars can be visible by the LISA. The simulated results show that the progenitors of these LISA sources within a distance of 1 kpc are WD-MS binaries with a donor star of $1.0-1.4~M_\odot$ (for initial WD mass of $0.5~M_\odot$) or $1.0-2.0~M_\odot$ (for initial WD mass of $0.7~M_\odot$), and an initial orbital period slightly smaller than the bifurcation period. Our simulations also indicate ten verification AM CVn sources can be reproduced by the standard magnetic braking model, and are potential LISA sources. Based on the birthrate of AM CVns simulated by the population synthesis, the birthrate of AM CVn-LISA sources evolving from the evolved donor star channel within a distance of 1 kpc can be estimated to be $(0.6-1.4)\times10^{-6}~\rm yr^{-1}$, and the predicted number of AM CVn-LISA sources is about $340-810$. Therefore, the evolved donor star channel play an important role in forming AM CVn-LISA sources in the Galaxy.

The event sample is selected from 2.8 fb$^{-1}$ of $p\bar{p}$ collisions recorded by D0 experiment in Run II of the Fermilab Tevatron Collider. The charge asymmetry $A_{CP}(B^+ \to J/ψK^+) = +0.0075 \pm 0.0061$(stat.)$\pm 0.0027$(syst.) is obtained using a sample of approximately 40 thousand $B^{\pm} \to J/ψK^{\pm}$ decays. The achieved precision is of the same level as the expected deviation predicted by some extensions of the standard model. We also measured the charge asymmetry $A_{CP}(B^+ \to J/ψπ^+) = -0.09 \pm 0.08$(stat.)$\pm 0.03$(syst.).

description: Nickel carbon nanotube composites with varying amounts of carbon nanotubes are deformed by high pressure torsion at different deformation temperatures to high strains, where no further refinement of the Nickel matrix microstructure is observed. Mean Nickel grain sizes increase with increasing HPT deformation temperature, while the size of the carbon nanotube agglomerates is significantly reduced. Additionally, the distribution of the agglomerates in the metal matrix becomes more homogenous. To investigate the mechanical performance of the HPT deformed composites, uniaxial tensile and compression tests are conducted. Depending on the HPT deformation temperature and the resulting microstructure, either brittle or ductile fracture occurs. Increased HPT deformation temperatures induce a decrease in the anisotropy of the mechanical properties, mainly caused by a shrinking of the carbon nanotube agglomerates. It is shown, that tuning the HPT deformation temperature is the key for optimizing both the microstructure and the mechanical performance.

description: The occurrence of inhomogeneous spin-density distribution in multilayered ferromagnetic diluted magnetic semiconductor nanostructures leads to strong dependence of the spin-polarized transport properties on these systems. The spin-dependent mobility, conductivity and resistivity in (Ga,Mn)As/GaAs,(Ga,Mn)N/GaN, and (Si,Mn)/Si multilayers are calculated as a function of temperature, scaled by the average magnetization of the diluted magnetic semiconductor layers. An increase of the resistivity near the transition temperature is obtained. We observed that the spin-polarized transport properties changes strongly among the three materials.

Identification of human macrophage genes differentially expressed by infection with Mycobacterium tuberculosis
Creators: name: Tang, Raymond Kwok-Cheung
Publisher: name: University of British Columbia
Year: 2009

description: Mycobacterium tuberculosis infects mononuclear phagocytes and manifests disease by triggering a strong delayed type hypersensitivity response which is detrimental to the host. In most healthy individuals, infection is resolved; however, the bacillus possesses many evasion strategies which may allow it under certain conditions to survive and replicate within the macrophage. M. tuberculosis has been found to alter several host defences to promote its survival so the ability of M. tuberculosis to modulate the expression of genes in human macrophages was investigated, using a novel method which combined subtractive hybridization with differential display. Macrophage genes which appeared to be induced or suppressed by infection were identified and isolated. A total of 25 such cDNAs were isolated. Five of the cDNAs were identified as known genes: NADH ubiquinone oxidoreductase chain 2; p22-phox; an antioxidant enzyme, AOE 37-2; a possible growth arrest gene, B4B; and a human protein phosphatase g. Seven other cDNAs matched human cDNA sequences, and the remaining 13 were novel sequences. Successful quantitation of three cDNAs revealed that two were induced in macrophages infected with M. tuberculosis, while the other was constitutively expressed. In addition, three other cDNAs were also identified to be induced by infection. The sequence of one of the cDNAs matched an IFNinducible nuclear phosphoprotein sequence, another matched a cDNA sequence, while the last one was unique. These cDNAs were clearly induced by infection in THP-1 macrophages; however, a pattern of expression of these clones did not emerge in human peripheral blood macrophages. Further research must be performed before conclusions can be made regarding the expression and function of these clones.

description: The quantum-limit Hall effect at $ν= nh/eB\sim O(1)$ that hosts a variety of exotic quantum phenomena requires demanding strong magnetic field $B$ and low carrier density $n$. We propose to realize quantum-limit Hall effect even in the presence of large carrier density residues $n_e$ and $n_h$ relative to the magnetic field $B$ in topological semimetals, where a single Fermi surface contour allow both electron-type and hole-type carriers and approaches charge neutrality as $n_e\sim n_h$. The underlying filling factor $ν= |n_e-n_h|h/eB$ explicitly violates the Onsager's relation for quantum oscillations.

description: Il 20% circa del patrimonio culturale inscritto nella lista mondiale dellʼUNESCO è di tipo religioso e rappresenta il patrimonio culturale più critico rispetto alla tutela, volta a garantire lʼautenticità, lʼintegrità ed il valore spirituale. Il valore immobiliare e la funzione turistica orientano verso determinati usi a causa della particolare localizzazione di questo patrimonio, spesso attrattiva per la centralità nel contesto territoriale. Ma questi nuovi usi sono coerenti con il “valore intrinseco” che li ha caratterizzati nel corso della loro secolare storia? Quali nuovi valori di uso non confliggono con la loro identità? E con lʼidentità delle comunità? Questo articolo si propone di analizzare la relazione tra “valore intrinseco” del patrimonio culturale e nuovi usi funzionali, identificando un set di criteri per la valutazione ex-post dei progetti di riuso del patrimonio culturale religioso nella prospettiva dellʼeconomia circolare come economia “rigenerativa” di valori economici, sociali, ambientali e culturali.

description: The scaling of the turbulent spectra provides a key measurement that allows to discriminate between different theoretical predictions of turbulence. In the solar wind, this has driven a large number of studies dedicated to this issue using in-situ data from various orbiting spacecraft. While a semblance of consensus exists regarding the scaling in the MHD and dispersive ranges, the precise scaling in the transition range and the actual physical mechanisms that control it remain open questions. Using the high-resolution data in the inner heliosphere from Parker Solar Probe (PSP) mission, we find that the sub-ion scales (i.e., at the frequency f ~ [2, 9] Hz) follow a power-law spectrum f^a with a spectral index a varying between -3 and -5.7. Our results also show that there is a trend toward and anti-correlation between the spectral slopes and the power amplitudes at the MHD scales, in agreement with previous studies: the higher the power amplitude the steeper the spectrum at sub-ion scales. A similar trend toward an anti-correlation between steep spectra and increasing normalized cross helicity is found, in agreement with previous theoretical predictions about the imbalanced solar wind. We discuss the ubiquitous nature of the ion transition range in solar wind turbulence in the inner heliosphere.

description: We show that the condensation of exciton-polaritons in semiconductor microcavities in an applied magnetic field manifests itself in the quenching of the Zeeman splitting of an elliptically polarized condensate. The circular polarization degree of a localized condensate with a finite number of particles increases as a function of the magnetic field with a step-like behavior. The width of each polarization step is fixed by the polariton-polariton interaction constants and the number of steps is fixed by the number of polaritons in the condensate. The magnetic susceptibility of the condensate depends qualitatively on the parity of the number of polaritons.

The mass spectrum of Kaluza-Klein (KK) gravitons in such a scheme is similar (although not equivalent) to that in a model with one extra dimension in a flat metric. The gravity effects in the processes $e^+e^- \to e^+e^-$ and $e^+e^- \toμ^+μ^-$ at the collision energy 1 TeV are presented. Our calculations are based on the previously obtained formula for virtual graviton contributions which takes into account both a discrete character of the mass spectrum and nonzero widths of the KK gravitons.

Analogamente a quanto emerso a scala edilizia, i protocolli di quartiere mostrano che i criteri di natura ambientale sono preponderanti su quelli sociali, nonostante siano in media più rappresentati nella dimensione urbana, confermando, anche se in misura minore, lʼequivoco fondamentale secondo cui la sostenibilità è intesa principalmente in termini ambientali, nonostante la sua natura fortemente antropocentrica. A partire dallo studio, lʼintegrazione e lʼimplementazione dei due principali protocolli di certificazione italiani a scala di quartiere, si propone un protocollo sperimentale, e una sua applicazione, in cui i diversi aspetti della sostenibilità delle aree urbane sono più ponderati con maggiore equilibrio, considerando fattore umano e sicurezza urbana.

description: We report on the storage and non-resonant parametric recovery of microwave signals carried by a dipolar surface spin-wave pulse in a thin ferrimagnetic film. The information about the intensity of the spectral components of the signal within a narrow frequency band is saved due to the excitation of a dipolar-exchange standing spin-wave mode across the film thickness and is afterwards restored by means of parametric amplification of this mode. The intensity of the restored signal measured for varying shifts between the signal carrier frequency and half of the pumping frequency, which is equal to the frequency of the standing mode, reveals information about the entire frequency spectrum of the input microwave signal.

description: We compute a new equation of state table including Bose-Einstein condensate of $K^{-}$ mesons for core collapse supernova and neutron star merger simulations. Nuclei and interacting nucleons in non-uniform matter is described in an extended version of the nuclear statistical equilibrium model including excluded volume effects whereas the uniform matter at higher densities is treated in the relativistic hadron field theory with density dependent couplings. The equation of state table is generated for a wide range of density ($10^{-12}$ to $\sim 1$ fm$^{-3}$), positive charge fraction (0.01 to 0.60) and temperature (0.1 to 158.48 MeV). The impact of antikaon condensate is investigated on different thermodynamic quantities for example free energy per baryon, entropy per baryon, pressure as well as compositions of matter. Furthermore, critical temperatures of antikaon condensation and the phase diagram of matter are also studied in this article.

description: A lattice model of the directed self-avoiding walk is used to estimate the possibility on the formation of an infinitely long linear semi-flexible copolymer chain. The copolymer chain is assumed to composed of four different types of the monomers. A method of the recursion relations is used to solve the proposed model analytically to show that the probability of the formation of a self-avoiding semi-flexible copolymer chain is independent of the stiffness of the chain. It is a distinct result from our earlier study on the formation of a Gaussian semi-flexible copolymer chain and the Gaussian chain is made up of these four monomers, [P. K. Mishra, J. of Adv. Appl. Sci. Res. 2(4) 1-8 (2020)]. We have also calculated the average number of different types of the bonding in the copolymer chain to show the distinctions in the behaviour of the self-avoiding copolymer chain from the Gaussian polymer chain.

description: ARCHITECTURE IN THE SCHOOLS Abstract The starting point for this paper was a school project in which the authors participated: the construction of a little building in wood, clay and straw, by 36 pupils of a third primary school class, in a German Waldorf school. The experience has stimulated the authors of the paper to deal with Waldorfʼs pedagogy, with the theme of “education to architecture” in schools in Germany and Europe, to make an overview of the state of the art in different European countries and to identify potential for future developments around the theme of “architecture for young people”, in Italy also. Keywords: teaching methodology, architecture, school

A critical part of any electric utility is managing the risk associated with cyber security and the power grid. For municipalities, cooperatives, and public power organizations with limited staff and budget, the challenge is to make the best decisions regarding risk mitigation and staying cognizant of cyber security regulations, standards, and best practices.

This report is the result of industry experts reviewing the challenges of smaller electric utilities and providing guidance in developing, maintaining and sustaining a cyber security program to maintain an acceptable risk profile. A significant portion of the report focuses on determining the appropriate cyber security regulations, standards, and best practices for optimizing available resources.

description: A semi-spectral Chebyshev method for solving numerically singular integral equations is presented and applied in the quarkonium bound-state problem in momentum space. The integrals containing both, logarithmic and Cauchy singular kernels, can be evaluated without subtractions by dedicated automatic quadratures. By introducing a Chebyshev mesh and using the Nystrom algorithm the singular integral equation is converted into an algebraic eigenvalue problem that can be solved by standard methods. The proposed scheme is very simple to use, is easy in programming and highly accurate.

description: The Milky Way is a spiral galaxy with the Schechter characteristic luminosity $L_*$, thus an important anchor point of the Hubble sequence of all spiral galaxies. Yet the true appearance of the Milky Way has remained elusive for centuries. We review the current best understanding of the structure and kinematics of our home galaxy, and present an updated scientifically accurate visualization of the Milky Way structure with almost all components of the spiral arms, along with the COBE image in the solar perspective. The Milky Way contains a strong bar, four major spiral arms, and an additional arm segment (the Local arm) that may be longer than previously thought. The Galactic boxy bulge that we observe is mostly the peanut-shaped central bar viewed nearly end-on with a bar angle of 25-30 degrees from the Sun-Galactic center line. The bar transitions smoothly from a central peanut-shaped structure to an extended thin part that ends around R ~ 5 kpc. The Galactic bulge/bar contains ~ 30-40% of the total stellar mass in the Galaxy. Dynamical modelling of both the stellar and gas kinematics yields a bar pattern rotation speed of ~ 35-40 km/s/kpc, corresponding to a bar rotation period of ~ 160-180 Myr. From a galaxy formation point of view, our Milky Way is probably a pure-disk galaxy with little room for a significant merger-made, "classical" spheroidal bulge, and we give a number of reasons why this is the case.

description: In this paper we continue our work on Schwartz functions and generalized Schwartz functions on Nash (i.e. smooth semi-algebraic) manifolds. Our first goal is to prove analogs of de-Rham theorem for de-Rham complexes with coefficients in Schwartz functions and generalized Schwartz functions. Using that we compute cohomologies of the Lie algebra of an algebraic group G with coefficients in the space of generalized Schwartz sections of G-equivariant bundle over a G-transitive variety M. We do it under some assumptions on topological properties of G and M. This computation for the classical case is known as Shapiro lemma.

description: Probabilistic shaping (PS) is investigated as a potential technique to approach the Shannon limit. However, it has been proved that conventional carrier phase recovery (CPR) algorithm designed for uniform distribution may have extra penalty in PS systems. In this paper, we find that the performance of QPSK partition algorithm is degenerated when PS is implemented. To solve this issue, a modified QPSK partition algorithm that jointly optimizes the amplitude decision threshold and filter weight is proposed, where the optimization of decision threshold is based on maximum a posterior probability (MAP) estimation. Different from the conventional decision methods which commonly use Euclidean distance metric, the MAP-based decision introduces the statistical characteristics of the received signals to obtain an accurate amplitude partition. In addition, the filter weight is optimized for different decision thresholds to enhance the tolerance of ASE-induced phase noise. We verify the feasibility of the proposed algorithm in a 56 GBaud PS 16-ary quadrature amplitude modulation (16-QAM) system. The proposed algorithm reduces the error of phase noise estimation by nearly half. Compared with conventional QPSK partition, the proposed algorithm could narrow the gap with theoretical mutual information (MI) by more than 0.1 bit/symbol. The channel capacity is increased by 4.2%, 4.3% and 3.6% with signal-to-noise ratio (SNR) from 8 dB to 10 dB respectively. These observations show that the proposed algorithm is a promising method to relieve the penalty of QPSK partition algorithm in PS systems.

description: We present a method to prepare magnetic spin torque devices of low specific resistance in a one step lithography process. The quality of the pillar devices is demonstrated for a standard magnetic double layer device. For single layer devices, we found hysteretic switching and a more complex dynamical excitation pattern in higher fields. A simple model to explain the resistance spikes is presented.

description: Using Planck scale oscillators in the background dark energy in a model that parallels the theory of phonons, we deduce the Planck mass, the elementary particle mass scale, the mass of the Universe and a recently discovered residual energy in the cosmic background. We also deduce the Beckenstein temperature formula for black holes. Finally we show that the model explains the four minute time lag in thearrival of gamma photons from a recently observed gamma flare by the MAGIC telescope.

Edge photogalvanic effect caused by optical alignment of carrier momenta in 2D Dirac materials

description: We show that the inter-band absorption of radiation in a 2D Dirac material leads to a direct electric current flowing at sample edges. The photocurrent originates from the momentum alignment of electrons and holes and is controlled by the radiation polarization. We develop a microscopic theory of such an edge photogalvanic effect and calculate the photocurrent for gapped and gapless 2D Dirac materials, also in the presence of a static magnetic field which introduces additional imbalance between the electron and hole currents. Further, we show that the photocurrent can be considerably multiplied in a ratchet-like structure with an array of narrow strips.

description: We determine all the correlators of the H3+ model on a disc with AdS2-brane boundary conditions in terms of correlators of Liouville theory on a disc with FZZT-brane boundary conditions. We argue that the Cardy-Lewellen constraints are weaker in the H3+ model than in rational conformal field theories due to extra singularities of the correlators, but strong enough to uniquely determine the bulk two-point function on a disc. We confirm our results by detailed analyses of the bulk-boundary two-point function and of the boundary two-point function. In particular we find that, although the target space symmetry preserved by AdS2-branes is the group SL(2,R), the open string states between two distinct parallel AdS2-branes belong to representations of the universal covering group.

Mathematical study of resonant wind-driven oceanic motions

description: We are interested here in describing the linear response of the ocean to some wind forcing, which admits fast time oscillations and may be resonant with the Coriolis force. In addition to the usual Ekman layer, we exhibit another - much larger - boundary layer, and some global vertical profile. That means in particular that the wind effect is no longer localized in the vicinity of the surface. From a mathematical point of view, the main novelty here is to introduce some systematic approach for the study of boundary effects.
