description: Der evolutionäre Erfolg vieler Tierlinien sowie das Funktionieren mariner Ökosysteme ist stark mit symbiotischen Assoziationen zwischen Wirbellosen und chemosynthetischen Mikroorganismen verbunden. In einer Untergruppe dieser Symbiosen gewinnt der wirbellose Wirt Energie in Form von organischem Kohlenstoff durch seine Symbionten, die Kohlenstoff synthetisieren können, indem sie reduzierte Schwefelverbindungen aus dem Sediment oxidieren. Bei diesen Assoziationen kann der Übertragungsmodus der Symbionten variieren, aber er spielt eine wichtige Rolle bei der Symbiose und wurde nur für wenige Arten aufgeklärt. Lucinidae, eine artenreiche Familie chemosymbiotischer Muscheln, waren zusammen mit ihrem horizontal übertragenen Symbionten Gegenstand intensiver Studien. Eine kürzlich durchgeführte Studie hat eine hohe Häufigkeit von mit Symbionten verwandten Bakterien in Verbindung mit Seegras beschrieben, aber Standorte mit gut untersuchten Luciniden waren nicht gut vertreten. Wir haben diese Studie durchgeführt, um herauszufinden, ob es Reservoire von Symbionten in Verbindung mit Loripes orbiculatus gibt. Umweltproben aus Porenwasser und Sedimenten aus der Bucht von Fetovaia, Elba, Italien, die 2016 und 2018 gesammelt wurden, und Proben aus Schleimröhren von Loripes orbiculatus aus Sant Carles de la Rapita, Spanien, die 2019 gesammelt wurden, sind auf die Anwesenheit des Symbionten und der Bakteriengemeinschaft analysiert worden. Um die Freisetzung von Symbionten aus toten und lebenden Muscheln zu untersuchen, wurde eine 16S-rRNA-Amplikon-Untersuchung an Sediment- und Porenwasserproben aus einem zwölftägigen Symbionten Freisetzungsexperiment durchgeführt. Die Anzahl der Symbionten wurde mittels ddPCR gemessen, wobei das Gen des schwefeloxidierenden Enzyms B, das für die Schwefeloxidation essentiell ist, als Ziel diente. Symbiont-rRNA-Genkopien wurden in Porenwasserfiltern und Schleimröhren nachgewiesen, die von der Muschel während des Sulfidabbaus und allgemeiner Grabaktivitäten gebaut werden. Die Sedimentproben aus der Bucht von Fetovaia enthielten keine übereinstimmenden rRNA Sequenzen des Genus in dem sich unser Symbiont befindet. Die Freisetzung des Symbionten konnte in Sedimentproben mit toten und lebenden Muscheln und einer Wasserprobe aus der Behandlung mit lebenden Muscheln nachgewiesen werden. Diese Ergebnisse deuten darauf hin, dass lucinide Muscheln durch Grabenaktivitäten angemessene Bedingungen für Symbionten schaffen und dass Muscheln, wenn auch unregelmäßig, eine Quelle für Umweltsymbionten sind.

description: Introduction: Prediction models using logistic regression may perform poorly in external patient cohorts. However, there is a need to standardize and validate models for clinical use. The purpose of this project was to describe a method for validation of external NTCP models used for patient selection in the randomized trial of protons versus photons in head and neck cancer radiotherapy, DAHANCA 35. Material and methods: Organs at risk of 588 patients treated primarily with IMRT in the randomized controlled DAHANCA19 trial were retrospectively contoured according to recent international recommendations. Dose metrics were extracted using MatLab and all clinical parameters were retrieved from the DAHANCA database. The model proposed by Christianen et al. to predict physician-rated dysphagia was validated through the closed testing, where change of the model intercept, slope and individual beta’s were tested for significant prediction improvements. Results: Six months prevalence of dysphagia in the validation cohort was 33%. The closed testing procedure for physician-rated dysphagia showed that the Christianen et al. model needed an intercept refitting for the best match for the Danish patients. The intercept update increased the risk of dysphagia for the validation cohort by 7.9 ± 2.5% point. For the raw model performance, the Brier score (mean squared residual) was 0.467, which improved significantly with a new intercept to 0.415. Conclusions: The previously published Dutch dysphagia model needed an intercept update to match the Danish patient cohort. The implementation of a closed testing procedure on the current validation cohort allows quick and efficient validation of external NTCP models for patient selection in the future.

description: Purpose: A 1.5 T MR Linac (MRL) has recently become available. MRL treatment workflows (WF) include online plan adaptation based on daily MR images (MRI). This study reports initial clinical experiences after five months of use in terms of patient compliance, cases, WF timings, and dosimetric accuracy. Method and materials: Two different WF were used dependent on the clinical situation of the day; Adapt To Position WF (ATP) where the reference plan position is adjusted rigidly to match the position of the targets and the OARs, and Adapt To Shape WF (ATS), where a new plan is created to match the anatomy of the day, using deformable image registration. Both WFs included three 3D MRI scans for plan adaptation, verification before beam on, and validation during IMRT delivery. Patient compliance and WF timings were recorded. Accuracy in dose delivery was assessed using a cylindrical diode phantom. Results: Nineteen patients have completed their treatment receiving a total of 176 fractions. Cases vary from prostate treatments (60Gy/20F) to SBRT treatments of lymph nodes (45 Gy/3F) and castration by ovarian irradiation (15 Gy/3F). The median session time (patient in to patient out) for 127 ATPs was 26 (21–78) min, four fractions lasted more than 45 min due to additional plan adaptation. For the 49 ATSs a median time of 12 (1–24) min was used for contouring resulting in a total median session time of 42 (29–91) min. Three SBRT fractions lasted more than an hour. The time on the MRL couch was well tolerated by the patients. The median gamma pass rate (2 mm,2% global max) for the adapted plans was 99.2 (93.4–100)%, showing good agreement between planned and delivered dose. Conclusion: MRL treatments, including daily MRIs, plan adaptation, and accurate dose delivery, are possible within a clinically acceptable timeframe and well tolerated by the patients.

description: Background: Proton dose distributions are sensitive to range uncertainties, resulting in margins added to ensure adequate tumor control probability (TCP). We investigated the required margin and dose shape needed to ensure adequate TCP, for representative tumor cell distributions in the clinical target volume (CTV). Material and methods: A mechanistic tumor response model, validated for lung tumors, was used to estimate TCP. The tumor cell distribution (ρ) was assumed to decrease exponentially in the CTV with decay parameter λ toward the outer border (xCTVmax). It was investigated if a gradual dose fall-off could reduce the dose to normal tissues outside the CTV, while achieving adequate TCP. For various values of xCTVmax and λ, we derived adequate uniform dose margins (m), coupled to linear dose fall-off regions (Δx, Δxnom=Δx−0.9 cm), that ensured TCP>TCPlimit, while delivering the least mean dose outside the CTV. To account for variabilities in patients and tumor types, variable probabilities (p) of finding tumor cells in the non-GTV part of the CTV for a given patient were also tested. Dose from a single beam or two opposing beams was simulated under the influence of a typical stopping power ratio uncertainty of 3.5%. Results: For large λ and xCTVmax, a dose distribution with a shallower dose fall-off (Δx>0) was advantageous, and m could be smaller than xCTVmax. In the case of small xCTVmax values, however, a conventional dose distribution (Δx=0) would generally perform better. For no CTV, m=0.4 cm in the case of two opposing beams, while it was 0.7 cm for a single beam, however, for two opposing beams Δx=1.2 cm (Δxnom=0.3 cm), while it was zero for a single beam. Conclusion: The details of the underlying cancer cell distribution characteristics do impact the adequate dose arrangements, and for opposing beams a non-conventional dose distribution shape is often advantageous.

description: The bilateral minimum distance of a binary linear code is the maximum $d$ such that all nonzero codewords have weights between $d$ and $n-d$. Let $Q\subset \{0,1\}^n$ be a binary linear code whose dual has bilateral minimum distance at least $d$, where $d$ is odd. Roughly speaking, we show that the average $L_\infty$-distance -- and consequently the $L_1$-distance -- between the weight distribution of a random cosets of $Q$ and the binomial distribution decays quickly as the bilateral minimum distance $d$ of the dual of $Q$ increases. For $d = Θ(1)$, it decays like $n^{-Θ(d)}$. On the other $d=Θ(n)$ extreme, it decays like and $e^{-Θ(d)}$. It follows that, almost all cosets of $Q$ have weight distributions very close to the to the binomial distribution. In particular, we establish the following bounds. If the dual of $Q$ has bilateral minimum distance at least $d=2t+1$, where $t\geq 1$ is an integer, then the average $L_\infty$-distance is at most $\min\{\left(e\ln{\frac{n}{2t}}\right)^{t}\left(\frac{2t}{n}\right)^{\frac{t}{2} }, \sqrt{2} e^{-\frac{t}{10}}\}$. For the average $L_1$-distance, we conclude the bound $\min\{(2t+1)\left(e\ln{\frac{n}{2t}}\right)^{t} \left(\frac{2t}{n}\right)^{\frac{t}{2}-1},\sqrt{2}(n+1)e^{-\frac{t}{10}}\}$, which gives nontrivial results for $t\geq 3$. We given applications to the weight distribution of cosets of extended Hadamard codes and extended dual BCH codes. Our argument is based on Fourier analysis, linear programming, and polynomial approximation techniques.

description: We investigate the nonlinear light-matter interaction of a Bose-Einstein condensate trapped in an external periodic potential inside an optical cavity which is weakly coupled to vacuum radiation modes and driven by a transverse pump field. Based on a generalized Bose-Hubbard model which incorporates a single cavity mode, we include the collective backaction of the atoms on the cavity light field and determine the nonequilibrium quantum phases within the nonperturbative bosonic dynamical mean-field theory.With the system parameters adapted to recent experiments, we find a quantum phase transition from a normal phase to a self-organized superfluid phase, which is related to the Hepp-Lieb-Dicke superradiance phase transition. For even stronger pumping, a self-organized Mott insulator phase arises.

description: We examine the Kogut-Susskind formulation of lattice gauge theories under the light of fermionic and bosonic degrees of freedom that provide a description useful to the development of quantum simulators of gauge invariant models. We consider both discrete and continuous gauge groups and adopt a realistic multi-component Fock space for the definition of matter degrees of freedom. In particular, we express the Hamiltonian of the gauge theory and the Gauss law in terms of Fock operators. The gauge fields are described in two different bases, based on either group elements or group representations. This formulation allows for a natural scheme to achieve a consistent truncation of the Hilbert space for continuous groups, and provides helpful tools to study the connections of gauge theories with topological quantum double and string-net models for discrete groups. Several examples, including the case of the discrete $D_3$ gauge group, are presented.

description: Semiclassical chiral fermion models with Berry term are studied in a symplectic framework. In the free case, the system can be obtained from Souriau's model for a relativistic massless spinning particle by "enslaving" the spin. The Berry term is identified with the classical spin two-form of the latter model. The Souriau model carries a natural Poincaré symmetry that we highlight, but spin enslavement breaks the boost symmetry. However the relation between the models allows us to derive a Poincare symmetry of unconventional form for chiral fermions. Then we couple our system to an external electromagnetic field. For gyromagnetic ratio $g=0$ we get curious superluminal Hall-type motions; for $g=2$ and in a pure constant magnetic field in particular, we find instead spiraling motions.

description: We investigate the viable exponential $f(R)$ gravity in the metric formalism with $f(R)=-βR_s (1-e^{-R/R_s})$. The latest sample of the Hubble parameter measurements with 23 data points is used to place bounds on this $f(R)$ model. A joint analysis is also performed with the luminosity distances of Type Ia supernovae and baryon acoustic oscillations in the clustering of galaxies, and the shift parameters from the cosmic microwave background measurements, which leads to $0.2401.47$ at 1$σ$ confidence level. The evolutions of the deceleration parameter $q(z)$ and the effective equations of state $ω_{de}^{eff}(z)$ and $ω_{tot}^{eff}(z)$ are displayed. By taking the best-fit parameters as prior values, we work out the transition redshift (deceleration/acceleration) $z_T$ to be about 0.77. It turns out that the recent observations are still unable to distinguish the background dynamics in the $Λ$CDM and exponential $f(R)$ models.

description: Nuclear transition matrix elements (NTME) for the neutrinoless double beta decay of $^{70}$Zn, $^{80}$Se and $^{82}$Se nuclei are calculated within the framework of the deformed shell model based on Hartree-Fock states. For $^{70}$Zn, jj44b interaction in $^{2}p_{3/2}$, $^{1}f_{5/2}$, $^{2}p_{1/2}$ and $^{1}g_{9/2}$ space with $^{56}$Ni as the core is employed. However, for $^{80}$Se and $^{82}$Se nuclei, a modified Kuo interaction with the above core and model space are employed. Most of our calculations in this region were performed with this effective interaction. However, jj44b interaction has been found to be better for $^{70}$Zn. The above model space was used in many recent shell model and interacting boson model calculations for nuclei in this region. After ensuring that DSM gives good description of the spectroscopic properties of low-lying levels in these three nuclei considered, the NTME are calculated. The deduced half-lives with these NTME, assuming neutrino mass is 1 eV, are $1.1 \times 10^{26}$ yr, $2.3 \times 10^{27}$ yr and $2.2 \times 10^{24}$ yr for $^{70}$Zn, $^{80}$Se and $^{82}$Se, respectively.

description: We present a measurement of the fundamental parameter of the standard model, the weak mixing angle, in $p\bar{p}\rightarrow Z/γ^{*}\rightarrow e^{+}e^{-}$ events at a center of mass energy of 1.96 TeV, using data corresponding to 9.7 fb$^{-1}$ of integrated luminosity collected by the D0 detector at the Fermilab Tevatron. The effective weak mixing angle is extracted from the forward-backward charge asymmetry as a function of the invariant mass around the Z boson pole. The measured value of $\sin^2θ_{\text{eff}}^{\text{$\ell$}}=0.23147 \pm 0.00047$ is the most precise measurement from light quark interactions to date, with a precision close to the best LEP and SLD results.

description: Cross-correlated measurements of thermal noise are performed to determine the electron temperature in nanopatterned channels of a GaAs/AlGaAs heterostructure at 4.2 K. Two-dimensional (2D) electron reservoirs are connected via an extended one-dimensional (1D) electron waveguide network. Hot electrons are produced using a current $I_{\text{h}}$ in a source 2D reservoir, are transmitted through the ballistic 1D waveguide and relax in a drain 2D reservoir. We find that the electron temperature increase $ΔT_{\text{e}}$ in the drain is proportional to the square of the heating current $I_{\text{h}}$, as expected from Joule's law. No temperature increase is observed in the drain when the 1D waveguide does not transmit electrons. Therefore, we conclude that electron-phonon interaction is negligible for heat transport between 2D reservoirs at temperatures below 4.2 K. Furthermore, mode control of the 1D electron waveguide by application of a top-gate voltage reveals that $ΔT_{\text{e}}$ is not proportional to the number of populated subbands $N$, as previously observed in single 1D conductors. This can be explained with the splitting of the heat flow in the 1D waveguide network.

title: Incels - Gewalt, Misogynie und Antifeminismus
Creators: name: Reininger, Julian
Year: 2022

description: Diese Masterarbeit dient als Grundlagenarbeit zu dem Themenfeld der Incel-Community, einem bislang noch wenig erforschten Teil der Mannosphäre. Sie besteht aus einem auf eigener Recherche sowie Literatur basierenden, systematisierenden Teil, der sich mit der Entstehung und der Geschichte der Incel-Community und mit den wesentlichen Aspekten des Weltbildes der Incels beschäftigt, sowie aus einem empirischen Teil, in welchem eine Diskursanalyse zu einem Post eines der größten Incel-Foren durchgeführt wird. Beide Teile dieser Masterarbeit beziehen sich dabei auf die Themenbereiche Gewalt, Misogynie und Antifeminismus, drei wesentliche Aspekte des Incel-Weltbildes. Der erste Teil geht auf fundamentale Elemente der Incel-Community wie die „Black Pill Theory“ ein, skizziert Terroranschläge, die von Incels durchgeführt wurden, und beleuchtet das misogyne Vokabular der Incel-Community sowie das „Feindbild Feminismus“. Im Rahmen des empirischen Teils wird nach der Methode von Siegfried Jäger eine Diskursanalyse eines Incel-Posts durchgeführt, der innerhalb der Incel-Community auf besonders große Resonanz gestoßen ist. Dieser Post wird in Hinblick auf die oben genannten Aspekte Gewalt, Misogynie und Antifeminismus analysiert. Die Diskursanalyse dient dazu, aufzuzeigen, wie innerhalb der Incel-Community argumentiert wird, um dieses gewaltvolle, misogyne und antifeministische Weltbild zu rechtfertigen. Im Schlusswort werden schließlich Möglichkeiten der Intervention und Gewaltprävention sowie offene Fragen für die künftige Forschung diskutiert.

description: Atom interferometric sensors and quantum information processors must maintain coherence while the evolving quantum wavefunction is split, transformed and recombined, but suffer from experimental inhomogeneities and uncertainties in the speeds and paths of these operations. Several error-correction techniques have been proposed to isolate the variable of interest. Here we apply composite pulse methods to velocity-sensitive Raman state manipulation in a freely-expanding thermal atom cloud. We compare several established pulse sequences, and follow the state evolution within them. The agreement between measurements and simple predictions shows the underlying coherence of the atom ensemble, and the inversion infidelity in an 80 micro-Kelvin atom cloud is halved. Composite pulse techniques, especially if tailored for atom interferometric applications, should allow greater interferometer areas, larger atomic samples and longer interaction times, and hence improve the sensitivity of quantum technologies from inertial sensing and clocks to quantum information processors and tests of fundamental physics.
Kaon Condensation in Baryonic Fermi Liquid at High Density

description: We formulate kaon condensation in dense baryonic matter with anti-kaons fluctuating from the Fermi-liquid fixed point. This entails that in the Wilsonian RG approach, the decimation is effectuated in the baryonic sector to the Fermi surface while in the meson sector to the origin. In writing the kaon-baryon (KN) coupling, we will take a generalized hidden local symmetry Lagrangian for the meson sector endowed with a "mended symmetry" that has the unbroken symmetry limit at high density in which the Goldstone $π$, scalar $s$, and vectors $ρ$ (and $ω$) and $a_1$ become massless. The vector mesons $ρ$ (and $ω$) and $a_1$ can be identified as emergent (hidden) local gauge fields and the scalar $s$ as the dilaton field of the spontaneously broken scale invariance at chiral restoration. In matter-free space, when the vector mesons and the scalar meson -- whose masses are much greater than that of the pion -- are integrated out, then the resulting KN coupling Lagrangian consists of the leading chiral order ($O(p^1)$) Weinberg-Tomozawa term and the next chiral order ($O(p^2)$) $Σ_{KN}$ term. In addressing kaon condensation in dense nuclear matter in chiral perturbation theory (ChPT), one makes an expansion in the "small" Fermi momentum $k_F$. We argue that in the Wilsonian RG formalism with the Fermi-liquid fixed point, the expansion is on the contrary in $1/k_F$ with the "large" Fermi momentum $k_F$. The kaon-quasinucleon interaction resulting from integrating out the massive mesons consists of a "relevant" term from the scalar exchange (analog to the $Σ_{KN}$ term) and an "irrelevant" term from the vector-meson exchange (analog to the Weinberg-Tomozawa term). It is found that the critical density predicted by the latter approach, controlled by the relevant term, is three times less than that predicted by chiral perturbation theory.

description: Jacobi/Poisson algebras are algebraic counterparts of Jacobi/Poisson manifolds. We introduce representations of a Jacobi algebra $A$ and Frobenius Jacobi algebras as symmetric objects in the category. A characterization theorem for Frobenius Jacobi algebras is given in terms of integrals on Jacobi algebras. For a vector space $V$ a non-abelian cohomological type object ${\mathcal J}{\mathcal H}^{2} \, (V, \, A)$ is constructed: it classifies all Jacobi algebras containing $A$ as a subalgebra of codimension equal to ${\rm dim} (V)$. Representations of $A$ are used in order to give the decomposition of ${\mathcal J}{\mathcal H}^{2} \, (V, \, A)$ as a coproduct over all Jacobi $A$-module structures on $V$. The bicrossed product $P \bowtie Q$ of two Poisson algebras recently introduced by Ni and Bai appears as a special case of our construction. A new type of deformations of a given Poisson algebra $Q$ is introduced and a cohomological type object $\mathcal{H}\mathcal{A}^{2} \bigl(P,\, Q ~|~ (\triangleleft, \, \triangleright, \, \leftharpoonup, \, \rightharpoonup)\bigl)$ is explicitly constructed as a classifying set for the bicrossed descent problem for extensions of Poisson algebras. Several examples and applications are provided.

title: Exploring stakeholder perceptions of apology in preventable and victim organitational crisis
Creators: name: Koridze, Elene
Year: 2022

description: Das Ziel dieser Studie ist es zu verstehen, was eine angemessene und effektive Entschuldigung (Apology) des Unternehmens in den vermeidbaren und Opferkrisen aus der Perspektive eines Stakeholders ist. Wenn die Organisationen verstehen, wonach Stakeholder in der Entschuldigung suchen, können sie möglicherweise auf eine Weise kommunizieren, die eine Einigung mit beleidigten Stakeholdern unterstützt und die den Ruf der Organisation effektiver repariert und ihre soziale Legitimität wiederherstellt. Dementsprechend, analysierte diese Studie die Entschuldigungen, die von Interessengruppen in den hypothetischen Krisenszenarien geschrieben wurden. Einhundert Teilnehmer wurden erbaten, die wirksame Entschuldigungen für den vermeidbare und Opfer Unternehmenskrisen zu schreiben, bei denen die Informationsquelle über die aufgetretene Krise die Datenschutzverletzung entweder die Medien oder die Organisation selbst waren. Das Experiment wurde als faktorielles 2X2 Design aus Faktoren (vermeidbar vs. Opfer) x (Medien vs. Organisation) Vergleich konstruiert. Schließlich, wurde eine faktorielle ANOVA (Zweiwege-ANOVA) durchgeführt, um die Haupteffekte verschiedener Arten von Krisen und verschiedener Arten von Informationsquellen auf abhängige Variablen zu vergleichen, die Entschuldigungen, die von Interessenvertretern geschrieben wurden.
description: The aim of this study is to understand what an appropriate and effective organizational apology is in the preventable and victim organizational crisis from the perspective of a stakeholder. When organizations understand what stakeholders look for in apologies, they may be able to communicate in ways that supports agreement with offended stakeholders. This will help organization to rebuild its ́ reputation and restore social legitimacy. Accordingly, this study analyzed apologies written by stakeholders in a hypothetical crisis scenarios. One hundred participants were asked to write effective apologies in preventable and victim organizational crisis where the source of information about occurred crisis - data breach, was either media or organization itself. The experiment was constructed as a 2X2 factorial design of factors (preventable vs. victim) X (media vs. organization) comparison. Finally, a factorial ANOVA (two way ANOVA) was conducted to compare main effects of different types of crisis and different types of sources of information on dependent variable, apologies written by stakeholders.
Inflationary dilaton-axion magnetogenesis

description: We discuss the generation of primordial magnetic fields during inflation in the dilaton-axion electromagnetism, in which the dilaton and axion dynamics are introduced in terms of two time dependent functions of the cosmic scale factor, $I(a) F^2/4$ and $J(a) F\tilde{F}/4$, respectively, where $F$ is the electromagnetic field strength and $\tilde{F}$ is its dual. We study the form of $J(a)$ that can generate a large seed magnetic field in the weak coupling regime, $I(a)<1$. Although the $J(a)$ function is model dependent, the axion-photon coupling indeed opens up a new window for a successful inflationary magnetogenesis.

description: We study the evolution of an initially confined atom condensate which is progressively outcoupled by gradually lowering the confining barrier on one side. The goal is to identify protocols that best lead to a quasi-stationary sonic black hole separating regions of subsonic and supersonic flow. An optical lattice is found to be more efficient than a single barrier in yielding a long-time stationary flow. This is best achieved if the final conduction band is broad and its minimum not much lower than the initial chemical potential. An optical lattice with a realistic Gaussian envelope yields similar results. We analytically prove and numerically check that, within a spatially coarse-grained description, the sonic horizon is bound to lie right at the envelope maximum. We derive an analytical formula for the Hawking temperature in that setup.

description: This paper proposes a systematic study of cosmological signatures of modifications of gravity via the presence of a scalar field with a multiplicative coupling to the electromagnetic Lagrangian. We show that, in this framework, variations of the fine structure constant, violations of the distance duality relation, evolution of the cosmic microwave background (CMB) temperature and CMB distortions are intimately and unequivocally linked. This enables one to put very stringent constraints on possible violations of the distance duality relation, on the evolution of the CMB temperature and on admissible CMB distortions using current constraints on the fine structure constant. Alternatively, this offers interesting possibilities to test a wide range of theories of gravity by analysing several datasets concurrently. We discuss results obtained using current data as well as some forecasts for future data sets such as those coming from EUCLID or the SKA.
