description: We present two new Lagrangian methods for hydrodynamics, in a systematic comparison with moving-mesh, SPH, and stationary (non-moving) grid methods. The new methods are designed to simultaneously capture advantages of both smoothed-particle hydrodynamics (SPH) and grid-based/adaptive mesh refinement (AMR) schemes. They are based on a kernel discretization of the volume coupled to a high-order matrix gradient estimator and a Riemann solver acting over the volume 'overlap.' We implement and test a parallel, second-order version of the method with self-gravity & cosmological integration, in the code GIZMO: this maintains exact mass, energy and momentum conservation; exhibits superior angular momentum conservation compared to all other methods we study; does not require 'artificial diffusion' terms; and allows the fluid elements to move with the flow so resolution is automatically adaptive. We consider a large suite of test problems, and find that on all problems the new methods appear competitive with moving-mesh schemes, with some advantages (particularly in angular momentum conservation), at the cost of enhanced noise. The new methods have many advantages vs. SPH: proper convergence, good capturing of fluid-mixing instabilities, dramatically reduced 'particle noise' & numerical viscosity, more accurate sub-sonic flow evolution, & sharp shock-capturing. Advantages vs. non-moving meshes include: automatic adaptivity, dramatically reduced advection errors & numerical overmixing, velocity-independent errors, accurate coupling to gravity, good angular momentum conservation and elimination of 'grid alignment' effects. We can, for example, follow hundreds of orbits of gaseous disks, while AMR and SPH methods break down in a few orbits. However, fixed meshes minimize 'grid noise.' These differences are important for a range of astrophysical problems.

description: ABSTRACT  Aim: A growing number of children throughout the globe are overweight or obese, which raises concerns about future rates of cardiovascular disease, diabetes, and cancer. Lipocalin-2, also known as LCN-2, is a glycoprotein that has been studied for more than ten years. It is well established that it rises in response to stressful circumstances, such as the presence of neoplastic disease, infection, inflammation, or ischemia. In recent years, several research have been conducted with the hypothesis that LCN 2 may serve as an early biomarker of renal ischemia. The purpose of this research is to evaluate the relationship between 24-hour urine LCN 2 levels and laboratory and clinical indicators in children who are overweight or obese. Method: Participants in our research ranged in age from 11 to 16 years old, and there was a total of 43 healthy obese participants and 32 healthy non-obese participants. We conducted anthropometric examinations and measurements. We examined the levels of cholesterol, LDL, and HDL in the blood as well as fasting serum glucose and insulin. The ELISA technique was used to assess the amounts of LCN 2 in urine collected over a period of 24 hours. The results of the analysis of the data gathered from this research were conducted using SPSS 15.0. We used Pearson correlation analyses to investigate the relationship between the independent factors. For the comparison between the obese group and the control group, a p-value of less than 0.05 was deemed statistically significant. Results: The levels of lipocaline and creatinine in the obese people's urine were significantly different from those in the control group after 24 hours (p 0.05). When we compare groups of obese people who are insulin resistant with obese people who are not insulin resistant, we find that the insulin resistant obese group has considerably higher 24-hour urine LCN 2 levels. (p<0.05) Conclusion: There may be a connection between insulin resistance and LCN 2 in urine collected over a 24-hour period in children who are obese. More research is necessary, both in youngsters and in large populations, for us to comprehend the part that LCN 2 plays in obesity

description: The growth of galaxies in the early Universe is driven by accretion of circum- and inter-galactic gas. Simulations predict that steady streams of cold gas penetrate the dark matter halos of galaxies, providing the raw material necessary to sustain star formation. We report a filamentary stream of gas that extends for 100 kiloparsecs and connects to the massive radio galaxy 4C 41.17. The stream is detected using sub-millimeter observations of the [CI] line of atomic carbon, a tracer of neutral atomic or molecular hydrogen gas. The galaxy contains a central gas reservoir that is fueling a vigorous starburst. Our results show that the raw material for star formation can be present in cosmic streams outside galaxies.

description: As well as primary fluctuations, CMB temperature maps contain a wealth of additional information in the form of secondary anisotropies. Secondary effects that can be identified with individual objects, such as the thermal and kinetic Sunyaev-Zel'dovich (SZ) effects due to galaxy clusters, are difficult to unambiguously disentangle from foreground contamination and the primary CMB however. We develop a Bayesian formalism for rigorously characterising anisotropies that are localised on the sky, taking the TSZ and KSZ effects as an example. Using a Gibbs sampling scheme, we are able to efficiently sample from the joint posterior distribution for a multi-component model of the sky with many thousands of correlated physical parameters. The posterior can then be exactly marginalised to estimate properties of the secondary anisotropies, fully taking into account degeneracies with the other signals in the CMB map. We show that this method is computationally tractable using a simple implementation based on the existing Commander component separation code, and also discuss how other types of secondary anisotropy can be accommodated within our framework.

description: Over half a century old and showing no signs of aging, k-means remains one of the most popular data processing algorithms. As is well-known, a proper initialization of k-means is crucial for obtaining a good final solution. The recently proposed k-means++ initialization algorithm achieves this, obtaining an initial set of centers that is provably close to the optimum solution. A major downside of the k-means++ is its inherent sequential nature, which limits its applicability to massive data: one must make k passes over the data to find a good initial set of centers. In this work we show how to drastically reduce the number of passes needed to obtain, in parallel, a good initialization. This is unlike prevailing efforts on parallelizing k-means that have mostly focused on the post-initialization phases of k-means. We prove that our proposed initialization algorithm k-means|| obtains a nearly optimal solution after a logarithmic number of passes, and then show that in practice a constant number of passes suffices. Experimental evaluation on real-world large-scale data demonstrates that k-means|| outperforms k-means++ in both sequential and parallel settings.

description: This working paper synthesises the specific understandings of the concept of Health System Resilience and related findings among the projects of the DFG-funded research unit PH-LENS “Refugee migration to Germany: a magnifying glass for broader public health challenges”. The synthesis is based on an interdisciplinary workshop, conducted in March 2022, by the NEXUS project as part of the Research Unit’s coordination measures. Different perspectives on Resilience, related to the individual, the community, the social welfare system, and the research projects themselves were identified and explored. Few projects used the term explicitly as analytical concept, but – despite controversies and the heterogeneity in conceptualising Resilience – a widely used theoretical framework, which distinguishes four capacities (Knowledge, Interdependency, Uncertainties, and Legitimacy) and three levels (Absorptive, Adaptive, and Transformative), turned out to be integrative. Due to the comprehensiveness of the four resilience capacities, all projects could relate to one or more of the four domains. This allowed to “contextualise” the local health systems beyond conventional building blocks by linking the system’s functions to social environments of refugees, such as migration-related challenges, the asylum system, housing conditions, or resource shortages.

description: In single electron tunneling through clean, suspended carbon nanotube devices at low temperature, distinct switching phenomena have regularly been observed. These can be explained via strong interaction of single electron tunneling and vibrational motion of the nanotube. We present measurements on a highly stable nanotube device, subsequently recorded in the vacuum chamber of a dilution refrigerator and immersed in the 3He/4He mixture of a second dilution refrigerator. The switching phenomena are absent when the sample is kept in the viscous liquid, additionally supporting the interpretation of dc-driven vibration. Transport measurements in liquid helium can thus be used for finite bias spectroscopy where otherwise the mechanical effects would dominate the current.

description: We study an intrinsic distribution, called polar, on the space of $l$-dimensional integral elements of the higher order contact structure on jet spaces. The main result establishes that this exterior differential system is the prolongation of a natural system of PDEs, named pasting conditions, on sections of the bundle of partial jet extensions. Informally, a partial jet extension is a $k$th order jet with additional $k+1$st order information along $l$ of the $n$ possible directions. A choice of partial extensions of a jet into all possible $l$-directions satisfies the pasting conditions if the extensions coincide along pairwise intersecting $l$-directions. We further show that prolonging the polar distribution once more yields the space of $(l,n)$-dimensional integral flags with its double fibration distribution. When $l>1$ the exterior differential system is holonomic, stabilizing after one further prolongation. The proof starts form the space of integral flags, constructing the tower of prolongations by reduction.

description: We consider the quantum angular momentum generators, deformed by means of the Dunkl operators. Together with the reflection operators they generate a subalgebra in the rational Cherednik algebra associated with a finite real reflection group. We find all the defining relations of the algebra, which appear to be quadratic, and we show that the algebra is of Poincare-Birkhoff-Witt (PBW) type. We show that this algebra contains the angular part of the Calogero-Moser Hamiltonian and that together with constants it generates the centre of the algebra. We also consider the gl(N) version of the subalgebra of the rational Cherednik algebra and show that it is a non-homogeneous quadratic algebra of PBW type as well. In this case the central generator can be identified with the usual Calogero-Moser Hamiltonian associated with the Coxeter group in the harmonic confinement.

description: Abstract: The purpose of this research work was to evaluate flours made from Wheat (Triticum aestivum), Sweet Potatoes (Ipomoea batatas) and Soybean (Glycine max), their blends and biscuits. Flours were produced from wheat, yellow fleshed sweet potato and soybean and blended into different ratios of 100:0:0 (WSS100), 75:20:5 (WSS75), 50:40:10 (WSS50), 25:60:15(WSS25) and 0:80:20 (WSS0). The flours were evaluated for proximate, functional and pasting properties while the biscuits were evaluated for proximate, Physical properties, and mineral properties using standard methods while sensory composition of the biscuit was determined using 20 semi-trained panelists. The results of the proximate composition of the flours showed that soybean had the highest protein (39.09%), fats (28.02%), crude fiber (5.01%), ash (2.19%) and energy content (491Kcal) while sweet potato had the highest carbohydrates (83.77%) and moisture content (8.91%).  Partially substituting wheat flour with sweet potato and soybean flour had a significant increase in the functional properties of the flour blends except for swelling capacity (72.50% - 62.30%) and bulk density (10.01% – 7.6g/ml) which had a significant decrease. The pasting properties of the flour blends decreased significantly with substitution in all the parameters except for the peak time (5.21mins – 6.07mins) and pasting temperature (57.12 oC – 67.27oC) which increased significantly. For the biscuits, there was a significant increase in their physical properties except for thickness (10.0 – 8.0mm) which decreased significantly. There was significant increase in the proximate composition of the biscuits with substitution except for the carbohydrate (75.61- 63.24%). The mineral content of the biscuits also increased significantly with substitution except for iron ( 5.81 – 3.40mg/100g) and zinc (2.13 – 1.52mg/100g) which had a significant decrease (p<0.5) with substitution. The biscuits from Sample WSS50 (50% wheat flour, 40% sweet potato flour and 10% soybean flour) were preferred in terms of taste, flavour, colour and overall acceptability while sample WSS25 (25% wheat flour, 60% sweet potato flour and 15% soybean flour) was preferred in terms of texture. Based on the findings of this research work, substituting wheat with sweet potatoes and soybeans in biscuit formulation and the likes will improve their nutritional quality, functional properties, physical and chemical properties, sensory and overall acceptability. This will also reduce the over dependence on wheat flour which is usually imported hence reducing the burden of importation which will lead to improved economy.
On Transmit Beamforming for MISO-OFDM Channels With Finite-Rate Feedback

description: With finite-rate feedback, we propose two feedback methods for transmit beamforming in a point-to-point MISO-OFDM channel. For the first method, a receiver with perfect channel information, quantizes and feeds back the optimal transmit beamforming vectors of a few selected subcarriers, which are equally spaced. Based on those quantized vectors, the transmitter applies either constant, linear, or higher-order interpolation with the remaining beamforming vectors. With constant interpolation, we derive the approximate sum achievable rate and the optimal cluster size that maximizes the approximate rate. For linear interpolation, we derive a closed-form expression for the phase rotation by utilizing the correlation between OFDM subcarriers. We also propose a higher-order interpolation that requires more than two quantized vectors to interpolate transmit beamformers, and is based on existing channel estimation methods. Numerical results show that interpolation with the optimized cluster size can perform significantly better than that with an arbitrary cluster size. For the second proposed method, a channel impulse response is quantized with a uniform scalar quantizer. With channel quantization, we also derive the approximate sum achievable rate. We show that switching between the two methods for different feedback-rate requirements can perform better than the existing schemes.

description: This paper deals with the relations among structural, topological, and chemical properties of the E.Coli proteome from the vantage point of the solubility/aggregation propensity of proteins. Each E.Coli protein is initially represented according to its known folded 3D shape. This step consists in representing the available E.Coli proteins in terms of graphs. We first analyze those graphs by considering pure topological characterizations, i.e., by analyzing the mass fractal dimension and the distribution underlying both shortest paths and vertex degrees. Results confirm the general architectural principles of proteins. Successively, we focus on the statistical properties of a representation of such graphs in terms of vectors composed of several numerical features, which we extracted from their structural representation. We found that protein size is the main discriminator for the solubility, while however there are other factors that help explaining the solubility degree. We finally analyze such data through a novel one-class classifier, with the aim of discriminating among very and poorly soluble proteins. Results are encouraging and consolidate the potential of pattern recognition techniques when employed to describe complex biological systems.

description: We study analytically the non-Markovianity of a spin ensemble, with arbitrary number of spins and spin quantum number, undergoing a pure dephasing dynamics. The system is considered as a part of a larger spin ensemble of any geometry with pairwise interactions. We derive exact formulas for the reduced dynamics of the system and for its non-Markovianity as assessed by the witness of Lorenzo et al. [Phys.Rev. A 88, 020102(R) (2013)]. The non-Markovianity is further investigated in the thermodynamic limit when the environment's size goes to infinity. In this limit and for finite-size systems, we find that the Markovian character of the system's dynamics crucially depends on the range of the interactions. We also show that when the system and its environment are initially in a product state, the appearance of non-Markovianity is independent of the entanglement generation between the system and its environment.

description: The COVID-19 pandemic has led to lifestyle changes across Europe with a likely impact on sleep quality. This investigation considers sleep quality in relation to the evolution of the COVID-19 pandemic in five European countries. Using panel regressions and keeping policy responses to COVID-19 constant, we show that an increase in the four-week average daily COVID-19 deaths/100,000 inhabitants (our proxy for the evolution of the pandemic) significantly reduced sleep quality in France, Germany, Italy, Spain, and Sweden between April 2020 and June 2021. Our results are robust to a battery of sensitivity tests and are larger for women, parents and young adults. Additionally, we show that about half of the reduction in sleep quality caused by the evolution of the pandemic can be attributed to changes in lifestyles, worsened mental health and negative attitudes toward COVID-19 and its management (lower degree of confidence in government, greater fear of being infected). In contrast, changes in one’s own infection-status from the SARS-CoV-2 virus or sleep duration are not significant mediators of the relationship between COVID-19-related deaths and sleep quality.

description: The report Summary: Large numbers of people are still employed in the production, marketing, and processing of flue-cured tobacco in the Southeastern United States. Mechanization and new technology in this industry, and the resulting displacement of workers, could constitute a problem of substantial social and economic proportions unless new employment opportunities are developed. Full mechanization of the tobacco industry, however, is tending to be inhibited by certain environmental forces. Uncertainty about future demand for tobacco products surely influences investment decisions of farmers. Government tobacco programs, which limit acreage and production and restrict leasing and rental arrangements, are largely barriers to the adoption of full-scale mechanization. Also, extensive program changes and rapid mechanization would have important implications for the people involved.

description: Linear dimensionality reduction methods are a cornerstone of analyzing high dimensional data, due to their simple geometric interpretations and typically attractive computational properties. These methods capture many data features of interest, such as covariance, dynamical structure, correlation between data sets, input-output relationships, and margin between data classes. Methods have been developed with a variety of names and motivations in many fields, and perhaps as a result the connections between all these methods have not been highlighted. Here we survey methods from this disparate literature as optimization programs over matrix manifolds. We discuss principal component analysis, factor analysis, linear multidimensional scaling, Fisher's linear discriminant analysis, canonical correlations analysis, maximum autocorrelation factors, slow feature analysis, sufficient dimensionality reduction, undercomplete independent component analysis, linear regression, distance metric learning, and more. This optimization framework gives insight to some rarely discussed shortcomings of well-known methods, such as the suboptimality of certain eigenvector solutions. Modern techniques for optimization over matrix manifolds enable a generic linear dimensionality reduction solver, which accepts as input data and an objective to be optimized, and returns, as output, an optimal low-dimensional projection of the data. This simple optimization framework further allows straightforward generalizations and novel variants of classical methods, which we demonstrate here by creating an orthogonal-projection canonical correlations analysis. More broadly, this survey and generic solver suggest that linear dimensionality reduction can move toward becoming a blackbox, objective-agnostic numerical technology.

description: Background: Integrated school and home garden interventions can improve health outcomes in low-income countries, but rigorous evidence remains scarce, particularly for school-aged children and to reduce anemia. Objective: We test if an integrated school and home garden intervention, implemented at pilot stage, improves hemoglobin levels among school children (aged 9-13 years) in a rural district in the mid-hills of Nepal. Methods: We use a cluster randomized controlled trial with 15 schools each in the control and treatment groups (n = 680 school children). To test if nutritional improvements translate into a reduction of anemia prevalence, hemoglobin data were collected 6 months after intervention support had ended. Using structural equation modeling, we estimate the direct and indirect effects of the treatment through several pathways, including nutritional knowledge, good food and hygiene practices, and dietary diversity. Results: The integrated school and home garden intervention did not lead to a direct significant reduction in anemia. Causal positive changes of the treatment on nutritional outcomes, although significant, are not strong enough to impact hemoglobin levels. The program improved hemoglobin levels indirectly for children below 12 by increasing the use of good food and hygiene practices at home. These practices are associated with higher hemoglobin levels, particularly for girls, young children, and in households where caregivers are literate. Conclusions: Even integrated school and home garden interventions are not sufficient to reduce anemia among school children. Incorporating behavioral change components around food and hygiene practices into integrated garden interventions is important to unlocking their health impacts.

description: The convolution powers of a perverse sheaf on an abelian variety define an interesting family of branched local systems whose geometry is still poorly understood. We show that the generating series for their generic rank is a rational function of a very simple shape and that a similar result holds for the symmetric convolution powers. We also give formulae for other Schur functors in terms of characteristic classes on the dual abelian variety, and as an example we discuss the case of Prym-Tjurin varieties.

description: Some individuals with chronic pain do not seek care. This decision may be due to characteristics of the individual, pain, and/or their health professional(s). This study aimed to identify and compare features of individuals with chronic pain, their pain and general health, and their health care professional between community-dwelling adults who did and did not seek care. Randomly selected adults were mailed a study questionnaire that screened for chronic pain (pain persisting ≥3 months) and asked about their general well-being (Short Form [SF]-36), pain location (body diagram), pain intensity and characteristics (Leeds Assessment of Neuropathic Symptoms and Signs), experiences with health care professionals (Chronic Illness Resources Survey), and visits made to health professionals over the past year. Respondents were categorized as help-seeking (≥1 visit in the past year) and non-help-seeking (zero visits in the past year). Six percent of respondents (44/696) were non-help-seeking. These respondents differed in individual, pain, and health care professional characteristics when compared to those who did seek care. Specifically, when other variables were controlled, non-help-seeking individuals were less likely to be male (relative risk [RR] = 0.39, 95% confidence interval [CI], 0.18–0.86), report comorbid conditions (RR = 0.46, 95% CI, 0.22–0.98), report being treated as an equal partner in decision making (RR = 0.40, 95% CI, 0.18–0.93), and rate their health care professional as important to their pain management (RR = 0.39, 95% CI, 0.18–0.85). They were more likely to use over-the-counter medication to manage their pain (RR = 2.52, 95% CI, 1.14–5.58). Experiences with health professionals play a role in determining whether an individual manages his or her pain independently. Future research should explore the safety of those who do not seek care.

description: We study the following quasilinear elliptic equation $$ -Δ_p u + (βΦ(x)-a(x)) u^{p-1} + b(x)g(u)=0 \quad \text{in } \mathbb{R}^N \quad \quad \quad (P_β) $$ where $p>1$, $Φ\in L^\infty_{loc}(\mathbb{R}^N)$, $a,b \in L^\infty(\mathbb{R}^N)$, $β,b,g \geq 0$. We provide a sharp criterion in terms of generalized principal eigenvalue for existence/nonexistence of positive solutions of ($P_β$) in suitable classes of functions. We derive the uniqueness result of ($P_β$) in those classes. Under additional conditions on $Φ$, we further show that : i) either for every $β\geq 0$ nonexistence phenomenon occurs, ii) or there exists a threshold value $β^*>0$ in the sense that for every $β\in [0,β^*)$ existence and uniqueness phenomenon occurs and for every $β\geq β^*$ nonexistence phenomenon occurs. In the latter case, we study the limits, as $β\to 0$ and $β\toβ^*$, of the sequence of positive solutions of $(P_β)$. Our results are new even in the case $p=2$.

description: Η εργασία αυτή μελετά την κρίση στις σχέσεις Κράτους και Εκκλησίας, όπως αυτή διαμορφώθηκε ύστερα από την νομοθετικές και ποικίλες άλλες παρεμβάσεις της Πολιτείας στο ζήτημα των 12 Μητροπολιτών, που χειροτονήθηκαν την περίοδο της Στρατιωτικής Δικτατορίας του 1967 – 1974 και κρίθηκαν από την Εκκλησία ως έκπτωτοι. Αν και το κύριο μέρος της κρίσης συναντάται στην δεκαετία του 1990, το πρόβλημα έχει τις ρίζες του από το 1974 όπου συναντούμε τα πρώτα σημάδια μονομερούς παρέμβασης της Πολιτείας. Η εργασία αντλεί από το αρχειακό υλικό όλων των εμπλεκομένων φορέων και των πολιτικών εφημερίδων της εποχής το ιστορικό περίγραμμα και τα γεγονότα που εξελίσσονταν διαρκούσης της κρίσης. Μέσα από την βιβλιογραφία επιπλέον αποτυπώνονται με αντικειμενικό τρόπο οι απόψεις αμφοτέρων των πλευρών για το ζήτημα.
description: This paper studies the crisis in the relations between the State and the Church, as it was formed after the legislative and various other interventions of the State during the issue of the 12 Metropolitans, who were ordained during the period of the Military Dictatorship of 1967 - 1974 and were judged by the Church as apostates. Although the main part of the crisis is found in the 1990s, the problem has its roots in 1974 where we find the first signs of the one-sided State intervention. The paper draws content from the archival material of all the involved bodies as well as the political newspapers of the time, the historical outline and the events which occurred during the crisis. Through the bibliography, the views of both sides of the issue are reflected in an objective regarding the aforementioned matter.

description: The amino acid glutamine plays an important role in cell growth and proliferation. Reliance on glutamine has long been considered a hallmark of highly proliferating cancer cells. Development of strategies for cancer therapy that primarily target glutamine metabolism has been an active area of research. Glutamine depletion is associated with growth arrest and apoptosis-induced cell death; however, the molecular mechanisms involved in this process are not clearly understood. Here, we show that glutamine depletion activates the energetic stress AMPK pathway and inhibits mTORC1 activity. Furthermore, inhibition of mTORC1 reduces the protein levels of β-TrCP, resulting in aberrant cell cycle progression and reduced proliferation. In agreement with the role of β-TrCP in glutamine metabolism, knockdown of β-TrCP resulted in proliferation and cell cycle defects similar to those observed for glutamine depletion. In summary, our results provide mechanistic insights into the role of glutamine metabolism in regulation of cell growth and proliferation via β-TrCP, uncovering a previously undescribed molecular process involved in glutamine metabolism.

description: Examinations of the reliability and validity of classification images of faces using the reverse correlation approach remain rare. In the present paper, we focus on order effects of trials, compliance and reliability effects, as well as the degree of contextual contrast of image pairs. We present different diagnostic methods to examine these three aspects using data from 12 reverse correlation studies conducted both in-lab and online with diverse samples (i.e., from Burkina Faso, China, the Netherlands, the U.S., and an international sample) using five different base faces (i.e., female Black, female Asian, female and gender-neutral White, and Black/White/female/male morphed composite). For each of the 12 studies, we compare the individual CIs of subgroups of likely non-complier respondents and trials with non-contrastful image pairs to individual CIs of likely compliers and contrastful image pairs. In an appendix, we also examine the effects of filtering out data from individual participants and trials on the signal-to-noise ratio of group CIs. R scripts are publicly available for easy implementation of our suggestions in related research.

description: Inspired by the study of mild transient reductions in the speed of sound of the adiabatic mode during inflation, we search for a primordial localized feature imprinted in cosmic microwave background and large-scale structure formation observables. We find some common oscillatory patterns both in the Planck CMB temperature-temperature power spectrum and the WiggleZ galaxy spectrum. By performing independent searches with these two data sets, we find a coincidence in the most significant mode previously found by Achúcarro et al. 2013 by using only Planck data. Furthermore, the joint data analysis shows that the oscillation frequency of the feature gets better constrained, and the amplitude marginally deviates from zero, unlike what was observed using only Planck data. Besides the parameter estimation, we also discuss the Bayesian evidence. The addition of WiggleZ data mildly enhances the significance of the best mode found in the Planck data.
