description: We analyze the spectra of non-chiral and chiral bifundamental mesons arising on intersecting D7-branes in $AdS_{5}\times S^{5}$. In the absence of magnetic flux on the curve of intersection, the spectrum is non-chiral, and the dual gauge theory is conformal in the quenched/probe approximation. For this case we calculate the dimensions of the bifundamental mesonic operators. We then consider magnetization of the D7-branes, which deforms the dual theory by an irrelevant operator and renders the mesons chiral. The magnetic flux spoils the conformality of the dual theory, and induces a D3-brane charge that becomes large in the ultraviolet, where the non-normalizable bifundamental modes are rapidly divergent. An ultraviolet completion is therefore necessary to calculate the correlation functions in the chiral case. On the other hand, the normalizable modes are very well localized in the infrared, leading to new possibilities for local model-building on intersecting D7-branes in warped geometries.

description: In a nanoscopic thin film of a strong topological insulator (TI) the Coulomb interaction in the channel that exchanges the two electrons with the same chirality in two different planes of the slab takes advantage of the minus sign resulting from such "exchange" and gives rise to a bound state between the positive energy states in one surface and the negative energy states in the opposite surfaces. Therefore particle and hole pairs in the {\em undoped} Dirac cone of the TI thin film form an inter-surface spin-singlet state that lies below the continuum of free particle-hole pairs. This mode is similar to the excitons of semiconductors, albeit formed between the electron and hole pairs from two different two-dimensional surfaces. For low-momenta the dispersion relation characterizing this collective mode is linear. Experimental comparison of two slabs with different thicknesses can capture the exponential dependence of the present effect on the slab thickness.

description: Firn-densification modeling based on hot isostatic pressing with power-law creep is investigated using depth-density data from 38 sites that collectively have mean annual temperatures ranging from 216 to 256 K and accumulation rates ranging from 0.022 to 1.2 m w. e. a-1. We use an inverse technique to obtain free parameters in a simple physical model for different stages of time-dependent firn densification. Our model works as well as or slightly better than previous models interpolating within the data range, but extrapolating would require additional physics.

description: Due to its exceptional electronic and thermal properties, graphene is a key material for bolometry, calorimetry, and photon detection. However, despite graphene's relatively simple electronic structure, the physical processes responsible for the transport of heat from the electrons to the lattice are experimentally still elusive. Here, we measure the thermal response of low-disorder graphene encapsulated in hexagonal boron nitride (hBN) by integrating it within a multi-terminal superconducting device coupled to a microwave resonator. This technique allows us to simultaneously apply Joule heat power to the graphene flake while performing calibrated readout of the electron temperature. We probe the thermalization rates of both electrons and holes with high precision and observe a thermalization scaling exponent consistent with cooling dominated by resonant electron-phonon coupling processes occurring at the interface between graphene and superconducting leads. The technique utilized here is applicable for wide range of semiconducting-superconducting interface heterostructures and provides new insights into the thermalization pathways essential for the next-generation thermal detectors.

title: Synthesis and Properties of Kinetically Stabilized Cyclohepta[def]fluorene Derivatives
Creators: name: Grieser, Udo
name: Hafner, Klaus
Publisher: name: Wiley
Year: 2022

description: The dihydrocyclohepta[def]fluorene 18 was prepared by starting from 2,7-di-tert-butylfluorene (11). Deprotonation of 18 furnished the dianion 3²⁻ in which the charge is mainly localized at the five- and seven-membered rings as evidenced by NMR investigations. Attempts to oxidize 3²⁻ to the uncharged species 3 failed. The ketones 26 and 29 were obtained by regioselective oxidation of 18. Deprotonation of 29 and 26 furnished the anions 4 and 5, respectively, which could be described as cyclohepta[def]fluorenes with a strong donor substituent. ¹³C-NMR spectroscopic investigations, however, revealed that 4 is described best as an acyl-substituted fluorenyl anion. In contrast to this, proof of the existence of the anion 5 could be obtained only from a trapping experiment.

description: We present intensity-resolved above threshold ionization (ATI) spectra of xenon using an intensity scanning and deconvolution technique. Experimental data were obtained with laser pulses of 58 fs and central wavelength of 800 nm from a chirped-pulse amplifier. Applying a deconvolution algorithm, we obtained spectra that have higher contrast and are in excellent agreement with characteristic 2 $U_p$ and 10 $U_p$ cutoff energies contrary to that found for raw data. The retrieved electron ionization probability is consistent with the presence of a second electron from double ionization. This recovered ionization probability is confirmed with a calculation based on the PPT tunneling ionization model [Perelomov, Popov, and Terent'ev, Sov. Phys. JETP 23, 924 (1966)]. Thus, the measurements of photoelectron yields and the proposed deconvolution technique allowed retrieval of more accurate spectroscopic information from the ATI spectra and ionization probability features that are usually concealed by volume averaging.

description: Triple threat processes and/or other forcings can lead to changes in the ocean happening fast and abruptly. These changes, referred to as “tipping points”, are critical thresholds in a marine system that, when exceeded, can lead to a significant change in the state of the system, which often can be irreversible. This presentation has been prepared with the financial support of Norges forskningsråd (Research Council of Norway) (309382) and the European Union’s Horizon 2020 research and innovation programme under grant agreement No 820989 (project COMFORT, Our common future ocean in the Earth system – quantifying coupled cycles of carbon, oxygen, and nutrients for determining and achieving safe operating spaces with respect to tipping points).

description: This software tool obtains an estimate of a noise signal collected as part of an electrocardiograph (ECG) recording. That is, this is a method to derive realistic noise-only signals by processing recorded ECGs containing physiologic ECG and noise/artifact components. The objective is to obtain representative samples of noise and motion artifacts from ECG devices under test that can then be used for assessing the robustness of ECG analysis algorithms and devices. This regulatory science tool obtains noise-only signals from ECGs acquired from healthy volunteers using an ECG acquisition device (for example including electrode materials and anatomical sensor locations of the final device). These noise-only signals can be obtained from ECGs collected during various realistic settings, such as, different positions and activity levels. The obtained noise-only signal added to databases of annotated ECG recordings yields an ECG under the various noise conditions that could represent a test signal for devices and analysis algorithms developed for ECG-based applications.

description: A natural one codimension isometric embedding of each $(n+1)$-dimensional spherical Robertson-Walker (RW) spacetime $I\times_f \mathbb{S}^n$ in $(n+2)$-dimensional Lorentz-Minkowski spacetime $\mathbb{L}^{n+2}$ permits to contemplate $I\times_f \mathbb{S}^n$ as a rotation Lorentzian hypersurface of $\mathbb{L}^{n+2}$. After a detailed study of such Lorentzian hypersurfaces, any $k$-dimensional spacelike submanifold of such an RW spacetime can be contemplated as a spacelike submanifold of $\mathbb{L}^{n+2}$. Then, we use that situation to study $k$-dimensional stationary (i.e., of zero mean curvature vector field) spacelike submanifolds of the RW spacetime. In particular, we prove a wide extension of the Lorentzian version of the classical Takahashi theorem, giving a characterization of stationary spacelike submanifolds of $I\times_f \mathbb{S}^n$ when contemplating them as spacelike submanifolds of $\mathbb{L}^{n+2}$.

description: We present the radial velocity curve of a single-lined spectroscopic binary in the faint Hercules dwarf spheroidal (dSph) galaxy, based on 34 individual spectra covering more than two years of observations. This is the first time that orbital elements could be derived for a binary in a dSph. The system consists of a metal-poor red giant and a low-mass companion, possibly a white dwarf, with a 135-days period in a moderately eccentric ($e=0.18$) orbit. Its period and eccentricity are fully consistent with metal-poor binaries in the Galactic halo, while the projected semimajor axis is small, at $a_p$ sin$i$ = 38 R$_{sun}$. In fact, a very close orbit could inhibit the production of heavier elements through $s$-process nucleosynthesis, leading to the very low abundances of neutron-capture elements that are found in this star. We discuss the further implications for the chemical enrichment history of the Hercules dSph, but find no compelling binary scenario that could reasonably explain the full, peculiar abundance pattern of the Hercules dSph galaxy.

Investigation of dynamic stall on a rotating model wind turbine using high-speed PIV

description: The turbulent conditions a wind energy converter is working in are resulting in strong angle of attack (AoA) fluctuations on the blades of the wind turbine rotor. As a consequence the lift force is constantly varying and phenomena as dynamic stall are occurring, inducing high turbine loads.
 In this study we investigate this phenomenon by means of particle image velocimetry (PIV) measurements on a rotating model wind turbine. The experiments took place in the 3 m times 3 m wind tunnel of the University of Oldenburg utilizing the Model Wind Turbine of Oldenburg (MoWiTO) [1] and a high-speed stereo PIV system. Figure 1 (a) is showing a picture of the used setup including an active grid for turbulence generation [2]. The flow around the three airfoil sections was captured at the 12 o’clock position using cyclic triggering at a sampling frequency of 5 kHz while the turbine was operating at a rotating speed of 480 rpm. Different positions at the blade root at 25%, 30% and 35% of the span were examined this way. To induce dynamic stall the blades of the turbine were pitched in a sinusoidal movement between -1° to 3° using the turbine’s individual pitch control. Stall clearly occurs at a pitch angle of -1°, corresponding to AoA of 13°, 10° and 9° for the investigated radial positions at steady operation. By shifting the phase of the pitching movement in respect to one rotation of the rotor different AoA can be visualized at the 12 o’clock position of the turbine blades. In Figure 1 (b) a result of these measurements is shown. The inflow is coming from the right and the turbine blade moving from the bottom to the top. Colour coded we can see the vorticity of the flow field around the wind turbine blade. Clearly we observe a separation of the flow at the suction side of the airfoil and the subsequent wake which is advected by the main flow.
 With this novel setup dynamic stall can be induced and examined thoroughly using a high frequent and non-intrusive measurement method. This results in a better understanding of the flow around the blade root of a down scaled model wind turbine in controlled wind tunnel conditions.

The Dynamical State of The Serpens South Filamentary Infrared Dark Cloud

description: We present the results of N$_2$H$^+$ ($J=1-0$) observations toward Serpens South, the nearest cluster-forming, infrared dark cloud. The physical quantities are derived by fitting the hyperfine structure of N$_2$H$^+$. The Herschel and 1.1-mm continuum maps show that a pc-scale filament fragments into three clumps with radii of $0.1-0.2$ pc and masses of $40-230M_\odot$. We find that the clumps contain smaller-scale ($\sim 0.04$ pc) structures, i.e., dense cores. We identify 70 cores by applying CLUMPFIND to the N$_2$H$^+$ data cube. In the central cluster-forming clump, the excitation temperature and line-width tend to be large, presumably due to protostellar outflow feedback and stellar radiation. However, for all the clumps, the virial ratios are evaluated to be $0.1-0.3$, indicating that the internal motions play only a minor role in the clump support. The clumps exhibit no free-fall, but low-velocity infall, and thus the clumps should be supported by additional forces. The most promising force is the globally-ordered magnetic field observed toward this region. We propose that the Serpens South filament was close to magnetically-critical and ambipolar diffusion triggered the cluster formation. We find that the northern clump, which shows no active star formation, has a mass and radius comparable to the central cluster-forming clump, and therefore, it is a likely candidate of a {\it pre-protocluster clump}. The initial condition for cluster formation is likely to be a magnetically-supported clump of cold, quiescent gas. This appears to contradict the accretion-driven turbulence scenario, for which the turbulence in the clumps is maintained by the accretion flow.

description: A new digital backend has been developed for the BEST-2 array at Radiotelescopi di Medicina, INAF-IRA, Italy which allows concurrent operation of an FX correlator, and a direct-imaging correlator and beamformer. This backend serves as a platform for testing some of the spatial Fourier transform concepts which have been proposed for use in computing correlations on regularly gridded arrays. While spatial Fourier transform-based beamformers have been implemented previously, this is to our knowledge, the first time a direct-imaging correlator has been deployed on a radio astronomy array. Concurrent observations with the FX and direct-imaging correlator allows for direct comparison between the two architectures. Additionally, we show the potential of the direct-imaging correlator for time-domain astronomy, by passing a subset of beams though a pulsar and transient detection pipeline. These results provide a timely verification for spatial Fourier transform-based instruments that are currently in commissioning. These instruments aim to detect highly-redshifted hydrogen from the Epoch of Reionization and/or to perform widefield surveys for time-domain studies of the radio sky. We experimentally show the direct-imaging correlator architecture to be a viable solution for correlation and beamforming.

description: To gain insight into the physical conditions and kinematics of the warm (100-1000 K) gas around the red hyper-giant VY CMa, we performed sensitive high spectral resolution observations of molecular lines in the sub-mm/FIR using the HIFI instrument of the Herschel Space Observatory. We observed CO, H2O, and other molecular species, sampling excitation energies from a few tens to a few thousand K. These observations are part of the Herschel Guaranteed Time Key Program HIFISTARS. We detected the J=6-5, J=10-9, and J=16-15 lines of 12CO and 13CO at about 100, 300, and 750K above the ground state (and the 13CO J=9-8 line). These lines are crucial for improving the modelling of the internal layers of the envelope around VY CMa. We also detected 27 lines of H2O and its isotopomers, and 96 lines of species such as NH3, SiO, SO, SO2 HCN, OH and others, some of them originating from vibrationally excited levels. Three lines were not unambiguously assigned. Our observations confirm that VY CMa's envelope must consist of two or more detached components. The molecular excitation in the outer layers is significantly lower than in the inner ones, resulting in strong self-absorbed profiles in molecular lines that are optically thick in this outer envelope, for instance, low-lying lines of H2O. Except for the most abundant species, CO and H2O, most of the molecular emission detected at these sub-mm/FIR wavelengths arise from the central parts of the envelope. The spectrum of VY CMa is very prominent in vibrationally excited lines, which are caused by the strong IR pumping present in the central regions. Compared with envelopes of other massive evolved stars, VY CMa's emission is particularly strong in these vibrationally excited lines, as well as in the emission from less abundant species such as H13CN, SO, and NH3.

description: The recovery of a 1.5 million yr long ice core from Antarctica represents a keystone of our understanding of Quaternary climate, the progression of glaciation over this time period and the role of greenhouse gas cycles in this progression. Here we tackle the question of where such ice may still be found in the Antarctic ice sheet. We can show that such old ice is most likely to exist in the plateau area of the East Antarctic ice sheet (EAIS) without stratigraphic disturbance and should be able to be recovered after careful pre-site selection studies. Based on a simple ice and heat flow model and glaciological observations, we conclude that positions in the vicinity of major domes and saddle position on the East Antarctic Plateau will most likely have such old ice in store and represent the best study areas for dedicated reconnaissance studies in the near future. In contrast to previous ice core drill site selections, however, we strongly suggest significantly reduced ice thickness to avoid bottom melting. For example for the geothermal heat flux and accumulation conditions at Dome C, an ice thickness lower than but close to about 2500 m would be required to find 1.5 Myr old ice (i.e., more than 700 m less than at the current EPICA Dome C drill site). Within this constraint, the resolution of an Oldest-Ice record and the distance of such old ice to the bedrock should be maximized to avoid ice flow disturbances, for example, by finding locations with minimum geothermal heat flux. As the geothermal heat flux is largely unknown for the EAIS, this parameter has to be carefully determined beforehand. In addition, detailed bedrock topography and ice flow history has to be reconstructed for candidates of an Oldest-Ice ice coring site. Finally, we argue strongly for rapid access drilling before any full, deep ice coring activity commences to bring datable samples to the surface and to allow an age check of the oldest ice.

description: Sphaeroceridae
This worldwide family of acalyptrate flies contains almost 1600 species (Evenhuis & Pape 2020) but presumably there are many more, predominantly tropical, ones waiting to be described (Marshall 2012). In his “ Stirps Copromyzinae ” rather than in the family Sphaeroceridae proposed by Macquart (1835), Rondani (1868b, 1880) described 24 Palaearctic and one South America nominal species. Ten of these are currently considered as valid and 15 are junior synonyms (Roháček 1983, Papp 1984 d, Norrbom & Kim 1986, Munari 1991, Canzoneri et al. 1995, Roháček & Marshall 2000, Roháček et al. 2001b, 2001 a, Marshall et al. 2011, Papp 2012, Kits & Marshall 2013). Rondani (1880) also proposed one new name in synonymy that was not made available by use as a valid species before 1961. Dipterists who have examined the type material in the MZUF and designated lectotypes are: Norrbom & Kim (1986) for Borborus limbinervis Rondani, 1880 and Borborus nigriceps Rondani, 1880, Roháček (1982) for Limosina caenosa Rondani, 1880, Limosina roralis Rondani, 1880, Roháček (1983) for Limosina akka Rondani, 1880, Limosina exigua Rondani, 1880, Limosina fulviceps Rondani, 1880, Limosina liliputana Rondani, 1880, Limosina luteilabris Rondani, 1880, Limosina nana Rondani, 1880, Limosina puerula Rondani, 1880, Limosina retracta Rondani, 1880, Roháček (1991) for Limosina cilifera Rondani, 1880, Limosina simplicimana Rondani, 1880, Roháček & Marshall (2000) for Limosina ciliosa Rondani, 1880. Allen L. Norrbom examined the type material of the nominal species of the genus Sphaerocera without publishing any results. Villeneuve (1914, 1918) and Kits & Marshall (2013) examined the type material in the MZUF without publishing any lectotype designation. Except for the type material of Sphaerocera pallidimana, which has been destroyed, the type material has been recovered for all nominal species and is distributed among the MZUF (24), OUMNH (two), MZUB (one) and MZLU (one).

description: Lines of sight with multiple, projected, cluster-scale halos have high total masses and complex lens plane interactions that can boost the area of magnification, or etendue, making detection of faint background sources more likely than elsewhere. To identify these new "compound" cosmic telescopes, we have found lines-of-sight with the highest integrated mass densities, as traced by the projected concentrations of Luminous Red Galaxies (LRGs). We use 1151 MMT Hectospec spectra to derive preliminary magnification maps for two such lines of sight with total mass exceeding ~ 3 x 10$^{15}$ Msun -- J0850+3604 (0850) and J1306+4632 (1306). We identify 2-3 group- and cluster-scale halos in each beam over 0.1 < z < 0.7, all of which are well-traced by LRGs. In Subaru Suprime-Cam imaging of beam 0850, we discover serendipitously a candidate multiply-imaged V-dropout source at z = 5.03, whose location is consistent with the critical curves for a source plane of $z_s$ = 5.03 predicted by our mass model. Incorporating the position of the candidate multiply-imaged galaxy as a constraint on the critical curve location in 0850 narrows the 68% confidence band on lens plane area with mu > 10 for a source plane of $z_s$ = 10 to [1.8, 4.2] square arcminutes, comparable to that of MACS 0717+3745 and El Gordo, two of the most powerful known single cluster lenses. The 68% confidence intervals on the lens plane area with mu > 10 for 1306 are [2.3, 6.7] square arcminutes. The significant lensing power of our beams makes them powerful probes of reionization and galaxy formation in the early Universe.

description: We introduce a disorder-free model of $S=1/2$ spins on the square lattice in a constrained Hilbert space where two up-spins are not allowed simultaneously on any two neighboring sites of the lattice. The interactions are given by ring-exchange terms on elementary plaquettes that conserve both the total magnetization as well as dipole moment. We show that this model provides a tractable example of strong Hilbert space fragmentation in two dimensions with typical initial states evading thermalization with respect to the full Hilbert space. Given any product state, the system can be decomposed into disjoint spatial regions made of edge and/or vertex sharing plaquettes that we dub as ``quantum drums''. These quantum drums come in many shapes and sizes and specifying the plaquettes that belong to a drum fixes its spectrum. The spectra of some small drums is calculated analytically. We study two bigger quasi-one-dimensional drums numerically, dubbed ``wire'' and a ``junction of two wires'' respectively. We find that these possess a chaotic spectrum but also support distinct families of quantum many-body scars that cause periodic revivals from different initial states. The wire is shown to be equivalent to the one-dimensional PXP chain with open boundaries, a paradigmatic model for quantum many-body scarring; while the junction of two wires represents a distinct constrained model.

Integrierte modell- und simulationsbasierte Entwicklung zur dynamischen Bewertung automobiler Elektrik/Elektronik-Architekturen

Year: 2020

description: Die Automobilbranche befindet sich seit einigen Jahren im Wandel. Trends wie autonomes Fahren, Konnektivität, smarte Mobilität sowie die Elektrifizierung führen zu einer drastischen Erhöhung der Fahrzeugkomplexität. Diese Komplexität muss durch die zugrunde liegende Elektrik/Elektronik-Architektur (E/E-Architektur) beherrscht werden und ruft unmittelbare neue Herausforderungen an den Entwicklungsprozess hervor. Design-Entscheidungen der E/E-Architektur haben maßgeblichen Einfluss auf das Verhalten von Fahrzeugfunktionen und umgekehrt. Daher müssen sie möglichst frühzeitig analysiert und evaluiert werden, um kostspielige Fehlerkorrekturen in späten Entwicklungsphasen zu minimieren. Eine frühzeitige Einbindung von Simulationsmethoden ist dabei zentral. Die modellbasierte Architekturentwicklung und Simulation sind jedoch weitestgehend getrennt voneinander laufende Prozesse. Dies erschwert eine effiziente Analyse sowie Bewertung der bidirektionalen Abhängigkeiten zwischen Architektur und Verhalten. Um diese Schwächen zu adressieren, wird in dieser Arbeit eine integrierte Methodik zur modell- und simulationsbasierten Entwicklung von E/E-Architekturen vorgestellt, die sich in drei Teile gliedert. Es werden zunächst neue Methoden zur architekturzentrierten Verhaltensmodellierung eingeführt. Eine nachfolgende Synthese generiert daraus ein Simulationsmodell, welches automatisiert mehrere Abstraktionsebenen der E/E-Architektur miteinander verknüpft und so zu einer ganzheitlichen Betrachtung beiträgt. Mithilfe des integrierten Ansatzes wird zusätzlich ein Konzept entwickelt, das es gestattet, mehrere Architekturvarianten automatisiert bzgl. statischen und dynamischen Metriken gegenüberzustellen. Die Konzepte werden in das in der Automobilindustrie etablierte E/E-Architekturwerkzeug PREEvision® integriert, umgesetzt und anhand mehrerer Anwendungsfälle evaluiert.

description: Cloud computing, undoubtedly, has become the buzzword in the IT industry today. Looking at the potential impact it has on numerous business applications as well as in our everyday life, it can certainly be said that this disruptive technology is here to stay. Many of the features that make cloud computing attractive, have not just challenged the existing security system, but have also revealed new security issues. This paper provides an insightful analysis of the existing status on cloud computing security issues based on a detailed survey carried by the author. It also makes an attempt to describe the security challenges in Software as a Service (SaaS) model of cloud computing and also endeavors to provide future security research directions.

description: We investigate the effects of horizontal radiative transfer (RT) a NLTE on important diagnostic iron lines in a realistic 3-D HD simulation. Using a multi-level atom we compute and compare widely used Fe I line profiles at 3 different levels of approximation (3-D NLTE, 1-D NLTE, LTE). We find that the influence of horizontal RT is of the same order of magnitude as that of NLTE, although spatially more localized. Also, depending on the temperature of the surroundings, horizontal RT is found to weaken or strengthen spectral lines. Line depths and equivalent width may differ by up to 20% against the corresponding LTE value if 3-D RT is applied. Residual intensity contrasts in LTE are found to be larger than those in 3-D NLTE by up to a factor of two. When compared to 1-D NLTE, we find that horizontal RT weakens the contrast by up to 30% almost independently of the angle of line of sight. While the CLV of the 1-D and 3-D NLTE contrasts are of similar form, the LTE contrast CLV shows a different run. The determination of temperatures by 1-D NLTE inversions of spatially resolved observations may produce errors of up to 200 K if one neglects 3-D RT. We find a linear correlation between the intensity difference of 1-D and 3-D NLTE and a simple estimate of the temperature in the horizontal environment of the line formation region. This correlation could be used to coarsely correct for the effects of horizontal RT in inversions done in 1-D NLTE. Horizontal RT is less important if one considers spatially averaged line profiles because local line strengthening and weakening occur with similar frequency in our HD atmosphere. Thus, the iron abundance is underestimated by 0.012 dex if calculated using 1-D NLTE RT. Since effects of horizontal RT are largest for spatially resolved quantities, the use of 3-D RT is particularly important for the interpretation of high spatial resolution observations.

description: Massive globular clusters (GCs) contain at least two generations of stars with slightly different ages and clearly distinct light elements abundances. The Na-O anticorrelation is the best studied chemical signature of multiple stellar generations. Low-mass clusters appear instead to be usually chemically homogeneous. We are investigating low-mass GCs to understand what is the lower mass limit where multiple populations can form, mainly using the Na and O abundance distribution. We used VLT/FLAMES spectra of giants in the low-mass, metal-poor GC Terzan 8, belonging to the Sagittarius dwarf galaxy, to determine abundances of Fe, O, Na, alpha-, Fe-peak, and neutron-capture elements in six stars observed with UVES and 14 observed with GIRAFFE. The average metallicity is [Fe/H]=-2.27+/-0.03 (rms=0.08), based on the six high-resolution UVES spectra. Only one star, observed with GIRAFFE, shows an enhanced abundance of Na and we tentatively assign it to the second generation. In this cluster, at variance with what happens in more massive GCs, the second generation seems to represent at most a small minority fraction. We discuss the implications of our findings, comparing Terzan 8 with the other Sgr dSph GCs, to GCs and field stars in the Large Magellanic Cloud, Fornax, and in other dwarfs galaxies.
