title: Physical and Chemical Properties of Matrix in Primitive Chondrites
Creators: name: Vaccaro, Epifanio
Publisher: name: The Open University
Year: 2017

description: The origin and formation of our Solar System is an open research question, which the scientific community is trying to address. In this work was specifically investigated the fine grained matrix which is a mixture of fine-grained materials composed largely of amorphous silicate and sub-micrometre crystals forsterite and enstatite. This is thought to be the remnants of the dust and gas of the protoplanetary disk that allows us to better understand chemical and physical properties of this precursor material. Four pristine primitive meteorites were selected: Acfer 094 (C2-ung.), ALHA77307 (CO3), MIL 07687 (C3-ung.) and QUE 99177 (CR2). The ability of a new generation of SEM-EDX detector was tested, in order to acquire high-resolution element maps of fine grained matrix. This allowed the calculation of abundances, and size distribution of discrete grains of different phases (silicate vs. opaque). Data acquired suggest that the four meteorites can be split into two groups, ALHA77307-MIL 07687 and QUE 99177 and Acfer 094, based on differences in relative abundances and sizes of discrete grains in their matrix. Micro X-ray diffraction was also used for mineralogical phase identification of the matrix constituents allowing the estimation of their modal mineralogy. MIL 0768 and Acfer 094 were also investigated using Scanning Transmission X-ray Microscopy (STXM) which revealed predominantly oxidising conditions; some reducing conditions are also displayed by some grains, reflecting the mixed redox conditions of the solar nebula. Measurements of O-isotopic composition of matrix regions were performed, and revealed similarities to values previously reported for IDPs (Starkey et al. 2013,2014 Nakashima et al., 2012, Aleon et al., 2009), rather than those of bulk meteorites (Clayton & Mayeda, 1999). I infer that the observed differences between these matrix components within the meteorite reflect the heterogeneity of the protoplanetary disk. Although these meteorites are pristine, parent body processes have also affected the small matrix grains.
Opportunities along Vancouver's waterfront : a gateway to False Creek at Hadden Park
Creators: name: Whittaker, Anne-Marie

description: Local and regional patterns and qualities of form and topos are central to placemaking and imageability of a city. These qualities can support, enrich and dictate the functions, events and experience of place that are expressive and appropriate to that region. This idea is from both critical regionalism and the general notion that in great places, form and activities share a logical symbiosis with the landscape. The current planning approach for future development and design at Vancouver's waterfront does not fully capitalize on the qualities of landscape and its tremendous inherent opportunities for programming and design. As an alternate approach to locating future development, this project examines the regional landscape patterns and qualities of form and topos along the waterfront as a framework for locating new development opportunities along the waterfront. The landscape framework identifies six key landforms along the waterfront: the promontory, peninsula, escarpment, bay, narrows and inlet. Each landform is described through the use of the preposition and its 'role' in the City determined from this description. For example, a promontory and peninsula are prominent, locative features, described as out, above, and in front of. Located along a passage, its role is a landmark for navigation, a transportation node, lookout, historic marker, place for public art, etc. A concept design for a gateway to False Creek in Hadden Park is generated to demonstrate how the landscape framework is applied. Positioned at the entrance to False Creek and on a promontory, the park's strong association with the water and role as a 'gateway' within the City is a great place for a Boater Community and Welcome Centre. The concept design builds on the promontory as a main axis, extends public activities outward onto, the water, marks the gateway and creates a major public water transportation node. The landform and its landscape appropriate design becomes an imageable reference point within the City, hosts new public activities and generates additional meaning along the waterfront. Landscape based framework as a planning approach to future waterfront development ensures that key places within the City (for instance, viewpoints, landmarks, gateways, etc.) are marked and recognized. It provides a stronger link to Vancouver's regional identity, imageability within the urban fabric, and sense of place with exciting and meaningful opportunities.

description: The paper surveys the neoclassical theory of growth. As a preliminary, the meaning of the adjective "neoclassical" is discussed. The basic model is then sketched, and the conditions ensuring a stationary state are illustrated. The issue of the convergence to a stationary state (and that of the speed of convergence) is further considered. A discussion of "primary factors" opens the way to the "new" theory of growth, with endogenous technical progress. A number of extensions of the basic model are then recalled: two-sector and multi-sectoral models, overlapping generations models, the role of money in growth models.

description: This paper describes the architecture and implementation of the HERA-B framework for online calibration and alignment. At HERA-B the performance of all trigger levels, including the online reconstruction, strongly depends on using the appropriate calibration and alignment constants, which might change during data taking. A system to monitor, recompute and distribute those constants to online processes has been integrated in the data acquisition and trigger systems.

Critica della teoria neoclassica della crescita e della distribuzione (A Critique of the Neoclassical Theory of Growth and Income Distribution)

Subjects: subject: Distribution, Economic Growth, Growth, Income Distribution, Income
subject: O41, E25

description: The paper surveys the main theories of income distribution in their relationship with the theories of economic growth. First, the Classical approach is considered, focusing on the Ricardian theory. Then the neoclassical theory is discussed, highlighting its origins (Bohm-Bawerk, Wicksell, Clark) and the role of the aggregate production function. The emergence of a "Keynesian" theory of income distribution in the wake of Harrod's model of growth is then recalled together with the surprising resurgence of the neoclassical theory (following the contributions of Solow and Meade). But, as the paper shows, the neoclassical theory of income distribution lacks logical consistency and has shaky foundations, as has been revealed by the severe critiques moved to the neoclassical production function. Mainstream economic literature circumvents this problem by simply ignoring it; while the models of endogenous growth exclude the issue of distribution theory from their consideration. However, while mainstream economics bypasses the problems of income distribution, this is too relevant an issue to be ignored and a number of new research lines, briefly surveyed, try new approaches to it.

description: We present a derivation of the flavor neutrino states which describe neutrinos produced or detected in charged-current weak-interaction processes, including those operating in neutrino oscillation experiments. We also present a covariant derivation of the probability of neutrino oscillations which is consistent with the fact that flavor is Lorentz-invariant. Finally, we clarify the negative answers to three commonly asked questions: "Do charged leptons oscillate?"; "Is the standard phase wrong by a factor of 2?" "Are flavor neutrinos described by Fock states?".

description: Der ruhende Verkehr stellt, aufgrund der Verkehrsmengen im Bereich des MIV sowie NMIV und der daraus resultierenden Flächeninanspruchnahme, einen essentiellen Bestandteil der (Stadt-) Verkehrsplanung, sowie der Verkehrspolitik dar. Im Zuge der vorliegenden Diplomarbeit wird das Ziel verfolgt, ein Instrumentarium zu entwickeln, das Parkraummanagement, die Verkehrspolitik auf kommunaler Ebene in Österreich, unterstützen soll, den ruhenden NMIV sowie MIV zu steuern. Den Vorteil, welchen das Parkraummanagement im Vergleich zu anderen Steuerungsstrategien besitzt besteht darin, dass dieses sich nicht ausschließlich auf Parkräume im öffentlichen Straßenraum bezieht, sondern zusätzlich Maßnahmen bietet, die sich auch auf halböffentlich zugängliche sowie private Parkräume auswirken. Es wird gezeigt, dass das Parkraummanagement vier Arten von Maßnahmenbündel umfasst: - ordnungspolitische - technologische - bauliche und - ökonomische (preispolitische) Maßnahmen Diese können einzeln sowie in Kombination eingesetzt werden, um das Parkraumangebot bzw. die Parkraumnachfrage zu steuern. Abschließend wird der Umsetzungsprozess eines Parkraummanagements auf kommunaler Ebene aufbereitet und die einzelnen Arbeitsschritte erläutert.
description: Stationary traffic is, due to its increasing use of public space, an essential part of urban development, traffic planning and transport policy. Basically, the main challenge for a spatial or traffic planner is in general that increasingly more motorized and non-motorized vehicles are both claiming the limited public space. The goal of this thesis is to develop a set of parking management instruments that support local government-s policy to control stationary traffic of motorized and non-motorized vehicles. In contrast to other strategic mechanisms the advantage of parking management is that it does not solely focus on on-street parking, but rather provides additional measures to control all types of parking space usage of public off-street parking, private non-residential off-street parking and private residential parking. I will show in this thesis that parking management includes four types of measures: - regulatory mechanisms - physical measures - technological measures and - economic (price policy) mechanisms, These types can be used individually or in combination to control the offer and demand of parking space. Moreover, the implementation process of parking management in governmental structures will be highlighted and each process step will be explained in detail.
4-point function from conformally coupled scalar in AdS$_6$

description: We explore conformally coupled scalar theory in AdS$_{6}$ extensively and their classical solutions by employing power expansion order by order in its self-interaction coupling $λ$. We study holographic correlation functions of scalar operator deformations to a certain 5-dimensional conformal field theory where the operators share the same scaling dimension $Δ=3$, from the classical solutions. For our solutions, we choose a scheme where we remove co-linear divergences of momenta along the AdS boundary directions which frequently appear in the classical solutions. This shows clearly that the holographic correlation functions are free from the co-linear divergences. It turns out that this theory provides correct conformal 2- and 3- point functions of the $Δ=3$ scalar operators as expected in previous literature. It makes sense since 2- and 3- point functions are determined by global conformal symmetry not being dependent on the details of the conformal theory. We also get 4-point function from this holographic model. In fact, it turns out that the 4-point correlation function is not conformal because it does not satisfy the special conformal Ward identity although it does dilation Ward identity and respect $SO(5)$ rotation symmetry. However, in the co-linear limit that all the external momenta are in a same direction, the 4-point function is conformal which means that it satisfy the special conformal Ward identity. We inspect holographic $n$-point functions of this theory which can be obtained by employing a certain Feynman-like rule. This rule is a construction of $n$-point function by connecting $l$-point functions each other where $l

The article introduces the new issue of the journal. It discusses what reasons may explain the fact that austerity measures are increasingly criticised by vast numbers of economists while they are still endorsed by all EU institutions. It is here suggested that the neoliberal stance seem to have gradually shifted away from the economic debate to move to a moralistic and a juridical level, focussed on the formal legitimacy (within the given institutional setup) of the proposed policy alternatives to tackle the euro crisis while neglecting and abstaining from criticising their underlying rationale. This ‘retreat’ allows for defunct economic theories to still dominate the political debate. JEL: F33, B50, E12

The $μ$SR data indicate that the whole muon ensemble senses spontaneous internal fields in the magnetic phase, demonstrating that magnetism occurs in the whole sample volume. This points to a microscopic coexistence between magnetism and heavy-fermion superconductivity.

description: Biological systems rely on robust internal information processing: Survival depends on highly reproducible dynamics of regulatory processes. Biological information processing elements, however, are intrinsically noisy (genetic switches, neurons, etc.). Such noise poses severe stability problems to system behavior as it tends to desynchronize system dynamics (e.g. via fluctuating response or transmission time of the elements). Synchronicity in parallel information processing is not readily sustained in the absence of a central clock. Here we analyze the influence of topology on synchronicity in networks of autonomous noisy elements. In numerical and analytical studies we find a clear distinction between non-reliable and reliable dynamical attractors, depending on the topology of the circuit. In the reliable cases, synchronicity is sustained, while in the unreliable scenario, fluctuating responses of single elements can gradually desynchronize the system, leading to non-reproducible behavior. We find that the fraction of reliable dynamical attractors strongly correlates with the underlying circuitry. Our model suggests that the observed motif structure of biological signaling networks is shaped by the biological requirement for reproducibility of attractors.

title: Negotiating Gender Identity, Motherhood and Consumption: Examining the Experiences of South Asian Women in the UK
Creators: name: Kerrane, Kathryn Ellen
Publisher: name: The Open University
Year: 2017

description: This exploratory study aims to understand the role of consumption for South Asian mothers living in the UK as they incorporate motherhood into their gender identities. Consumer research on motherhood suggests mothers’ consumption practices are intertwined with the dominant norms of good mothering that pervade many cultures, known as intensive mothering. To fulfil the norms of intensive mothering, mothers are expected to consume appropriately and devote intense amounts of effort to ensuring their child’s development, both during the transition to motherhood and beyond. However much of this research focusses predominantly on white, middle-class mothers. Relatively little is known about the consumption practices of mothers at other intersecting positions in society, such as ethnic minority women. Yet recent sociological research suggests that increasing numbers of South Asian women are transforming gender norms surrounding education, work and marriage as they negotiate access to university. This thesis seeks to understand the complex ways in which South Asian women negotiate new gender identities on becoming mothers, and the role of consumption in this process. In-depth interviews with 23 South Asian mothers living in the UK were used to gain insight into participants’ lived experiences of becoming a mother and their everyday mothering and consumption practices. The findings show that during the transition to motherhood, there were two ways in which participants’ accounts of consuming appropriately differed from that shown in existing consumer research. First, participants typically embraced certain South Asian cultural practices surrounding birth, which meant that participants often delayed purchasing baby products until after birth. Second, participants’ consumption of expert advice was more complex, due to the higher status of advice from female family members within family hierarchies. Beyond the transition to motherhood, mothering and consumption practices such as housework, parenting, feeding the family, and childcare consumption are key sites in which many participants negotiate the norms of intensive mothering as they pursue a more egalitarian division of these responsibilities on returning to work/study. The thesis contributes to consumer research on gender identity by how participants are positioned to challenge gender norms through their consumption practices. Participants regard motherhood as an opportunity to reflect on how they socialise their children; they develop new ways of transmitting elements of their cultural and religious heritage to their children. Rather than simply coping with these additional responsibilities, participants often view motherhood as an opportunity to socialise their children with more egalitarian gender norms.

description: During the LHC Run-I (2010-2013) and Run-II (2015-2018), the selection of interesting events for muon physics in ALICE was performed with a dedicated muon trigger system, based on 72 single-gap bakelite Resistive Plate Chambers (RPCs), operated in maxi-avalanche mode (ADULT front-end electronics without amplification and a threshold of 7 mV). From Run-III (starting in 2021) on, in order to fully profit from the increased luminosity of Pb-Pb collisions, the ALICE experiment will run in continuous readout (triggerless) mode and the muon trigger system (MTR) will become a Muon Identifier (MID). The read-out electronics is being upgraded in order to support continuous readout. Moreover, in order to increase the RPC rate capability and to mitigate possible aging effects, it was decided to operate the detectors with a lower gain, and to replace the ADULT front-end cards with new cards (FEERIC), equipped with an amplification stage. Also, an upgrade of the threshold distribution system to the front-end will allow one to tune thresholds at the single front-end card level, while this was previously only possible at the single-RPC level. Finally, since some of the RPCs currently installed in ALICE have integrated a non-negligible charge with respect to their certified life-time, about 25% of the detectors will be replaced with new ones, built with a different type of bakelite laminates. A detailed description of the MTR upgrade and of its current status will be presented in this contribution.

description: Axial facet joint interventions (e.g., medial branch block and radiofrequency ablation, facet joint intra-articular injection) are commonly performed for managing chronic spinal pain. Although traditionally performed with fluoroscopy or computed tomography (CT) guidance, ultrasound-guided techniques have also been developed for these interventions. The aim of this study is to present contemporary ultrasound-guided techniques for facet joint interventions and synthesize data addressing their accuracy, safety, and efficacy. The PubMed, MEDLINE, CINAHL, Embase, and Cochrane Central Register of Controlled Trials databases were systematically searched for studies of ultrasound-guided facet joint interventions with human subjects from November 1, 1992, to November 1, 2022. Additional sources were drawn from reference lists and citations of relevant studies. We found 48 studies assessing ultrasound-guided facet joint interventions. Ultrasound guidance for injection of the cervical facet joints and their innervating nerves had favorable accuracy (78%–100%), with lower procedural time compared to fluoroscopy or CT guidance and comparable pain relief. Accuracy with ultrasound-guided lumbar facet joint intra-articular injection (86%–100%) was more reliable than medial branch block (72%–97%); analgesia was comparable to fluoroscopy and CT guidance. In general, these procedures were more challenging for patients with obesity, and deeper structures were more difficult to accurately target (e.g., lower cervical levels, L5 dorsal ramus). Ultrasound-guided facet joint interventions continue to evolve. Some technically challenging interventions may be impractical for widespread usage or require further technical refinement. The utility of ultrasound guidance with obesity and abnormal anatomy may be reduced.

Our work is based on the analysis of classical kinetic equations for massive particles with spin-1/2, with the collision terms treated in the relaxation time approximation. The kinetic-theory framework determines the structure of viscous and diffusive terms and allows to explicitly calculate a complete set of new kinetic coefficients that characterize dissipative spin dynamics.

description: Yoga integrates all aspects of self, with biological, mental, intellectual, and spiritual elements. The practice of yoga aligns with the biopsychosocial model of health and, as such, it can be instrumental in pain treatment. The purpose of this qualitative study was to explore perceptions regarding the yoga sessions for chronic pain through thematic content analysis with comparison of gender, veteran or civilian status, and delivery methods. Patients with chronic pain attended a 5-week intensive interdisciplinary chronic pain management program at the Michael G. DeGroote Pain Clinic. Participants were asked to complete six open-ended questions following four weekly 1-h yoga classes, through in-person or virtual delivery. Survey responses were thematically and separately analyzed by reviewers. Forty-one (N = 41) participants (56% males, 71% veterans) with an average age of 50.87 (SD 10.10) years provided comments. Nine themes emerged: (1) mind and body are one through yoga practices; (2) meaningful practice of yoga basics is productive for range of motion/movement, tension in joints, and chronic pain; (3) yoga classes provide an enjoyable process of learning; (4) yoga reminds patients of their physical capabilities; (5) routine practices lead to improvements; (6) yoga improved on strategies for chronic pain; (7) yoga can be adapted for each patient; (8) mindset improves to include positive thinking, better focus, and willingness to try new things; and (9) improvements exist for the current yoga programming. Findings of the current study were nine qualitative themes that present the experience of patients with chronic pain in the yoga sessions.

description: We present sub-milliarcsecond observations of SiO masers in the late-type stars IRC +10011 and Chi Cyg. We have used the NRAO Very Long Baseline Array (VLBA) to map the 43 GHz (v=1, 2 J=1-0) and the 86 GHz (v=1, 2 J=2-1) SiO masers. All the transitions have been imaged except the v=2 J=2-1 in IRC +10011. We report the first VLBI map of the v=1 J=2-1 28SiO maser in IRC +10011 as well as the first VLBA images of SiO masers in an S-type Mira variable, Chi Cyg. In this paper we have focused on the study of the relative spatial distribution of the different observed lines. We have found that in some cases the observational results are not reproduced by the current theoretical pumping models, either radiative or collisional. In particular, for IRC +10011, the v=1 J=1-0 and J=2-1 28SiO lines have different spatial distributions and emitting region sizes, the J=2-1 emission being located in an outer region of the envelope. For Chi Cyg, the distributions also differ, but the sizes of the masing regions are comparable. We suggest that the line overlaps between ro-vibrational transitions of two abundant molecular species, H2O and 28SiO, is a possible explanation for the discrepancies found between the observations and the theoretical predictions. We have introduced this overlapping process in the calculations of the excitation of the SiO molecule. We conclude that the line overlaps can strongly affect the excitation of SiO and may reproduce the unexpected observational results for the two sources studied.

More precisely it is our purpose to show that property (c) of Cabello's proof, stating that ``local observables can be measured by means of tests on individual qubits" is definitely false since it has been obtained by a wrong use of the basic rules of the quantum formalism, while property (b), stating that ``distant local setups do not need to be aligned since the require perfect correlations are achieved for any local rotation of the setups", is also wrong due to the failure of validity of property (c).

description: We address the diffusion of information about the COVID-19 with a massive data analysis on Twitter, Instagram, YouTube, Reddit and Gab. We analyze engagement and interest in the COVID-19 topic and provide a differential assessment on the evolution of the discourse on a global scale for each platform and their users. We fit information spreading with epidemic models characterizing the basic reproduction numbers $R_0$ for each social media platform. Moreover, we characterize information spreading from questionable sources, finding different volumes of misinformation in each platform. However, information from both reliable and questionable sources do not present different spreading patterns. Finally, we provide platform-dependent numerical estimates of rumors' amplification.

description: We present modeling and analysis of a hysteretic deformable mirror where the facesheet interacts with a continuous layer of piezoelectric material that can be actuated distributively by a matrix of electrodes through multiplexing. Moreover, a method for calculating the actuator influence functions is described considering the particular arrangement of electrodes. The results are presented in a semi-analytical model to describe the facesheet's deformation caused by a high density array of actuators, and validated in a simulation. The proposed modeling of an interconnection layout of electrodes is used to determine the optimal pressures the actuators have to exert for achieving a desired surface deformation.

description: L'articolo discute il contributo di Aldo Montesano in questo numero, con un focus particolare sulle definizioni di economia e di economia politica.Nel tentativo di rispondere se l'economia è una disciplina morale e se si tratta di una scienza, l'articolo evidenzia che diverse scuole di economisti hanno interpretato e definito in modo diverso ciò che riguarda l'economia.Si sottolinea che nessuno di questi approcci è nato ed è ora morto, ma prospettive ancora diverse coesistono.Per questo motivo è importante da un lato consentire il pluralismo e dall'altro non sostenere le rappresentazioni caricaturali della disciplina. The article comments on the contributions by Aldo Montesano and Roberto Cellini in this number, in particular focussing on the evolution of economic thought and the changing definitions of economics and of political economy. It is here argued that the historical evolution of the discipline should induce economists to abstain from providing a precise definition of their science; and this conclusion is reinforced by the observation that contrasting assessments of the discipline and of its content matter make such a definition even more problematic. The article argues that economists even disagree on what Schumpeter called the pre-analytical vision of society and the economy, and it is therefore obvious that they developed alternative definitions of what economics is.

description: Additive manufacturing is a free-form manufacturing technique in which parts are built in a layer-by-layer manner. Laser powder bed fusion is one of the popular techniques used to fabricate metal parts. However, it induces residual stress and distortion during fabrication that adversely affects the mechanical properties and dimensional accuracy of the manufactured parts. Therefore, predicting and avoiding the residual stress and distortion are critical issues. In this study, we propose a topology optimization method that accounts for the distortion. First, we propose a computationally inexpensive analytical model for additive manufacturing that uses laser powder bed fusion and formulated an optimization problem. Next, we approximate the topological derivative of the objective function using an adjoint variable method that is then utilized to update the level set function via a time evolutionary reaction-diffusion equation. Finally, the validity and effectiveness of the proposed optimization method was established using two-dimensional design examples.

description: Die Planung und Umsetzung von Schieneninfrastrukturprojekten ist eine Herausforderung für alle Beteiligten. Von der Idee über die Umsetzung bis hin zur Eröffnung vergeht oft eine Zeitspanne von mehreren Jahren oder sogar Jahrzehnten. Dabei kann es sein, dass sich das Projekt in diesem Zeitraum aufgrund der unterschiedlichsten Einflussfaktoren verändert und weiterentwickelt. Es ist aber auch möglich, dass die Einflüsse die Umsetzung des Vorhabens verhindern. Aufgrund der Vielschichtigkeit von solchen Unterfangen können schon kleinste Einflüsse eine große Wirkung haben und das Projekt nachhaltig beeinflussen. In dieser Arbeit wird versucht, anhand eines geplanten regionalen Nahverkehrsprojekts die maßgeblichen Einflussfaktoren auf Schieneninfrastrukturprojekte zu identifizieren und zu kategorisieren. Als Beispielprojekt dient die in Planung befindliche RegioTram Linz-Gallneukirchen-Pregarten, die von der oberösterreichischen Landeshauptstadt in das nordöstliche Umland führen soll. In weiterer Folge werden die ermittelten Faktoren einer Bewertung unterzogen und deren Übertragbarkeit auf andere Schienenprojekte überprüft.
description: Planning and realising rail infrastructure projects is challenging for all the parties involved and it may take many years or even decades from the initial idea of a project until its completion. Over such a long period of time a lot of different factors can influence the project. These influencing factors may lead to changes in the project's orientation or even to its cancellation. Due to the complexity of infrastructure projects even the smallest factors can have a great impact on the processes of planning and realisation. This work tries to identify and classify the relevant factors that influence infrastructure projects. The planned Light-Rail Connection between the capital of Upper Austria, Linz, and the north-eastern urban hinterland around the municipalities of Gallneukirchen and Pregarten is used as an example for this procedure. Subsequently the identified factors are grouped whether or not they can be seen as indispensable for the project. The final step is to investigate the applicability of these factors to similar projects.

description: We compute the Kaluza-Klein spectrum of the non-supersymmetric SO(3)$\,\times\,$SO(3)-invariant AdS$_4$ vacuum of 11-dimensional supergravity, whose lowest-lying Kaluza-Klein modes belong to a consistent truncation to 4-dimensional ${\cal N}=8$ supergravity and are stable. We show that, nonetheless, the higher Kaluza-Klein modes become tachyonic so that this non-supersymmetric AdS$_4$ vacuum is perturbatively unstable within 11-dimensional supergravity. This represents the first example of unstable higher Kaluza-Klein modes and provides further evidence for the AdS swampland conjecture, which states that there are no stable non-supersymmetric AdS vacua within string theory. We also find 27 infinitesimal moduli amongst the Kaluza-Klein modes, which hints at the existence of a family of non-supersymmetric AdS$_4$ vacua.

A Time-Dependent Radiative Model of HD209458b

description: We present a time-dependent radiative model of the atmosphere of HD209458b and investigate its thermal structure and chemical composition. In a first step, the stellar heating profile and radiative timescales were calculated under planet-averaged insolation conditions. We find that 99.99% of the incoming stellar flux has been absorbed before reaching the 7 bar level. Stellar photons cannot therefore penetrate deeply enough to explain the large radius of the planet. We derive a radiative time constant which increases with depth and reaches about 8 hr at 0.1 bar and 2.3 days at 1 bar. Time-dependent temperature profiles were also calculated, in the limit of a zonal wind that is independent on height (i.e. solid-body rotation) and constant absorption coefficients. We predict day-night variations of the effective temperature of \~600 K, for an equatorial rotation rate of 1 km/s, in good agreement with the predictions by Showman &Guillot (2002). This rotation rate yields day-to-night temperature variations in excess of 600 K above the 0.1-bar level. These variations rapidly decrease with depth below the 1-bar level and become negligible below the ~5--bar level for rotation rates of at least 0.5 km/s. At high altitudes (mbar pressures or less), the night temperatures are low enough to allow sodium to condense into Na2S. Synthetic transit spectra of the visible Na doublet show a much weaker sodium absorption on the morning limb than on the evening limb. The calculated dimming of the sodium feature during planetary transites agrees with the value reported by Charbonneau et al. (2002).
