description: In IMPETUS, 125 citizen science initiatives (CSIs) are supported, through a comprehensive training and mentoring programme (Accelerator), to develop and maximise their scientific, social, economic, democratic, and environmental impacts towards the Sustainable Development Goals (UN SDGs) and the Green Deal targets. These CSIs are divided into 3 cohorts, 2023-2024-2025. The Accelerator will support both new CSIs "kickstarting projects" (100) and already existing ones "Sustaining projects" (25). 
This deliverable describes the IMPETUS Accelerator approach, objectives and logic and how its implementation is planned. The Accelerator is coordinated by Science for Change (WP2 leader) and aims at setting up an impact-driven citizen science program to support each CSI cohort.

FreeWheel Service Design Challenges
Creators: name: Luccarelli, Tiziano
Publisher: name: Zenodo
Year: 2018

description: Working on defining a set of Service Design Challenges for FreeWheel has been extremely stimulating. There was the chance to have a cohesive reading at all the work previously done in the various WPs, the deliverables, the internal reports. The team played all the qualitative interviews once again; going through the Stories Repository. The main efforts were on setting a solid ground not only for the upcoming activities in the project but also for the future (and promising) exploitation of the results after the end of it. The Service Design Challenges selected in the end, are representing a well-balanced and determined intention to hold the human-centered design approach to the core of the project.

description: Age segmentation in the labor force can be analyzed in terms of the age distributions of occupations. In this paper we show that the majority of detailed census occupations conform to one of five basic age profiles. Further, these age profiles have meaning as they derive from the operation of well-defined institutional forces. We discuss the relevance of industry for a refined understanding of occupational-age patterns and conclude with some observations about the likely consequence of a change in the age of compulsory retirement for the age distributions of different occupations.
title: Shaping of laser-accelerated ion beams for applications in high energy density physics
Creators: name: Metternich, Martin
Publisher: name: UNSPECIFIED
Year: 2023

description: The goal of this work was the generation of a suitable ion beam for specific applications with a laser-driven ion beamline, which was realized within the Laser Ion Generation Handling and Transport (LIGHT) collaboration at GSI Helmholtzzentrum für Schwerionenforschung GmbH. For this purpose, the influence of the beam shaping on the initial properties of the laser-generated ion beam has first been characterized in detail. In addition, equations have been derived to calculate the required magnetic and electric field strengths of the beamline components for the applications under investigation. These findings have then been used to determine the optimal setup of the LIGHT beamline for the following three applications: • The injection of the ion beam into the heavy ion synchrotron SIS18 at GSI • The generation and investigation of high proton fluxes • The generation of a suitable ion beam for the measurement of the stopping power of dense, highly ionized plasmas Subsequently, the expected beam parameters for these setups were determined by numerical simulations and verified experimentally. According to the numerical simulations, the current setup of the LIGHT beamline can inject 3 × 10⁸ protons with an energy of 11.4 MeV into the SIS18 synchrotron at GSI in one shot. Since the synchrotron can accommodate more than 10¹⁰ protons, proposals have also been elaborated to increase the number of particles for this application. With respect to the generation of high proton fluxes, in an experimental campaign that was carried out as part of this work, a proton bunch with (7.72 ± 0.14) MeV and a particle flux of (3.28 ± 0.24) × 10⁸ ns⁻¹ mm⁻² was achieved. Of particular note is the temporal width of this proton bunch, which was only (742 ± 40) ps (FWHM). Furthermore, the corresponding simulations for this experiment revealed that the cross-shaped ion beam profile in pulsed high-field solenoid beamlines, which is shown on the cover of this thesis, is caused by the magnetic field of the connecting cables of the solenoid magnets. These results have been published in [Metternich et al., 2022]. Finally, the generation of a suitable ion beam for measuring the stopping power of dense, highly ionized plasmas was investigated and experimentally performed using the LIGHT beamline. The resulting ion beam had an energy of (0.60 ± 0.02) MeV u⁻¹ and a temporal width of (1.23 ± 0.04) ns (FWHM). Moreover, it could be estimated that (2.0 ± 0.6) × 10⁶ carbon ions of this bunch will penetrate the spatially homogeneous region of the plasma under investigation in the planned experiment, i.e., three orders of magnitude more particles than in previous measurements at GSI with a temporal bunch width comparatively almost five times shorter. The measurement of the stopping power of dense, highly ionized plasmas with the beam parameters achieved in this work should therefore lead to much lower measurement uncertainties than in the experiments performed so far.

description: Most analyses of single-molecule experiments consist of binning experimental outcomes into a histogram and finding the parameters that optimize the fit of this histogram to a given data model. Here we show that such an approach can introduce biases in the estimation of the parameters, thus great care must be taken in the estimation of model parameters from the experimental data. The bias can be particularly large when the observations themselves are not statistically independent and are subjected to global constraints, as, for example, when the iterated steps of a motor protein acting on a single molecule must not exceed the total molecule length. We have developed a maximum-likelihood analysis, respecting the experimental constraints, which allows for a robust and unbiased estimation of the parameters, even when the bias well exceeds 100%. We demonstrate the potential of the method for a number of single-molecule experiments, focusing on the removal of DNA supercoils by topoisomerase IB, and validate the method by numerical simulation of the experiment.
Controlling Several Atoms in a Cavity

description: We treat control of several two-level atoms interacting with one mode of the electromagnetic field in a cavity. This provides a useful model to study pertinent aspects of quantum control in infinite dimensions via the emergence of infinite-dimensional system algebras. Hence we address problems arising with infinite-dimensional Lie algebras and those of unbounded operators. For the models considered, these problems can be solved by splitting the set of control Hamiltonians into two subsets: The first obeys an abelian symmetry and can be treated in terms of infinite-dimensional Lie algebras and strongly closed subgroups of the unitary group of the system Hilbert space. The second breaks this symmetry, and its discussion introduces new arguments. Yet, full controllability can be achieved in a strong sense: e.g., in a time dependent Jaynes-Cummings model we show that, by tuning coupling constants appropriately, every unitary of the coupled system (atoms and cavity) can be approximated with arbitrarily small error.
SEARCHING FOR PHYSICS BEYOND THE STANDARD MODEL IN ATLAS WITH THE THIRD GENERATION QUARKS
Creators: name: FAVARETO, ANDREA
Publisher: name: Universit� degli Studi di Milano
Year: 2013

description: ATLAS (A Toroidal LHC Apparatus) is one of the general-purpose detectors at the CERN's Large Hadron Collider (LHC), designed to study proton- proton collisions at a center of mass energy of 14 TeV. This PhD thesis starts with a performance measurement of the Inner Detector, followed by the measurement of an interesting Standard Model process on early data in which tracking and b-tagging play a fundamental role. Finally a search for new physics on the high integrated luminosity sample is presented. It includes a detailed measurement of the tracks impact parameter resolution as a function on the pseudorapidity ?, the pT and the number of hits and shared hits in the silicon detectors of the tracks. The transverse impact parameter is measured to be ~10 ?m for high pT tracks (pT>20 GeV) in a central ? region with one hit in the innermost pixel layer (b-layer) and without shared hits with other tracks in the silicon detectors. Two measurements are then presented, that profit of this excellent resolution and the related b-tagging performance. The first measurement of the charge asymmetry in the production of top quark pairs in the semileptonic decay channel. A dataset corresponding to an integrated luminosity of 1.04 fb-1, obtained at a centre-of-mass energy of ?s=7 TeV is used. The charge asymmetry is determined using the differential distribution of the reconstructed observable|yt|-|yT|, where yt and yT denote the top and antitop quark rapidities, respectively. The total charge asymmetry after unfolding is measured to be -0.019 � 0.028 (stat.) � 0.024 (syst.) in agreement with the Standard Model prediction of (0.60�0.03)%. Finally, the results of a search for direct pair production of supersymmetric partners of the top quark in 4.7 fb-1 and 13.0 fb-1 of integrated luminosity from proton-proton collisions respectively collected at 7 TeV in 2011 and 8 TeV in 2012 are reported. Scalar top quarks decaying into a b-quark and a superymmetric chargino are searched for in events with two leptons in the final state. This events have a final state topology similar that of top-antitop events and this analysis builds up on the experience that I gained with the top-antitop charge asymmetry measurement. No excess above the Standard Model expectation is observed. A scalar top with mass between 150 and 450 GeV is excluded at 95% CL for a chargino approximately degenerate with the scalar top and a massless ligthest neutralino.

description: The aim of submitted paper was to analyze customer preferences in the context of loyalty to the brand of selected food products in the segment of yoghurts. In order to achieve the mentioned aim, we used methods of survey, structured questionnaire (sample of 693 randomly chosen respondents) and blind test (sample of 100 respondents testing the four yoghurts – 2 yoghurts of traditional brands and 2 yoghurts of private labels). For a deeper analysis of the obtained results, totally four hypotheses were set out and tested by using the statistical methods of Contingency table chi-square test, Pearson´s chi-square test, Cramer's coefficient, Friedman test and Kolmogorov-Smirnov Test. The results of the survey proved that more than 30 % of respondents consume yoghurts on a daily basis, 30 % of respondents prefer to buy the yogurts of private labels, more than 64 % of respondents consider themselves as loyal consumers and based on the package, the tested sample of private label yoghurt (sample A) would be purchased by 56 % of respondents while the same sample of yoghurt (sample A) would be purchased for its taste just by 47 % of respondents.

description: The phenomenon of photonic band gaps in one-dimensional optical lattices is reviewed using a microscopic approach. Formally equivalent to the transfer matrix approach in the thermodynamic limit, a microscopic model is required to study finite-size effects, such as deviations from the Bragg condition. Microscopic models describing both scalar and vectorial light are proposed, as well as for two- and three-level atoms. Several analytical results are compared to experimental data, showing a good agreement.

description: Fibre lasers have became increasingly important in applications such as polymer processing, laser surgery, defence and machining etc. The development of mid-infrared fibre lasers that can operate in robust environments in both continuous wave (CW) and pulsed mode is required. To date, there have only been few investigations in the development of mid-infrared light sources. We report the experimental results for ultrashort-pulsed Er-doped fibre lasers at 2800 nm emission wavelength using the 2D nanomaterials MXene and platinum deselinide (PtSe₂). The semiconductor device SESAM was used as a benchmark for the evaluation of the performance of these nanomaterials. CW mode-locked operation at 2800 nm has been achieved using both MXene and PtSe₂. We have identified the optimum number of layers for ink-jet printed MXene saturable absorbers and have used this knowledge to realise the first monolithic CW mode-locked mid-infrared fibre laser. The calculated theoretical minimum pulsewidth for this laser is 11.4 ps. In addition, we have also successfully demonstrated a Ho/Pr co-doped fibre laser operating in CWmode and emitting at the very longwavelength of 2.94 μm aimed for surgical applications. The slope efficiency is measured to be 7.78%. At 3.7W pump power, the output power of the laser is 256.7mW. The beam profile, which was measured using a CCD camera, confirms that the laser operates in the fundamental transverse mode. Stability tests have been conducted at 530.8 mW and 2.67 W pump powers over a period of two hours, and the laser has a very stable output power in both cases.

description: Naturally occurring networks exhibit quantitative features revealing underlying growth mechanisms. Numerous network mechanisms have recently been proposed to reproduce specific properties such as degree distributions or clustering coefficients. We present a method for inferring the mechanism most accurately capturing a given network topology, exploiting discriminative tools from machine learning. The Drosophila melanogaster protein network is confidently and robustly (to noise and training data subsampling) classified as a duplication–mutation–complementation network over preferential attachment, small-world, and a duplication–mutation mechanism without complementation. Systematic classification, rather than statistical study of specific properties, provides a discriminative approach to understand the design of complex networks.

description: The age-adjusted risk for lung cancer among over 120,000 male current cigarette smokers in the American Cancer Society's 1959-1972 prospective study was analyzed according to tar yield and quantity smoked per day. At each quantity level, the risk increased with increasing tar yield, and at each tar level, the risk increased with numbers of cigarettes smoked daily. The risks in smokers of cigarettes with the lowest yields, however, far exceeded those of former smokers and nonsmokers. The excess lung cancer risk for current smokers was directly proportional to the estimated total milligrams of tar consumed daily: SMR = 100 + 1.731 × milligrams tar per day. Tar yields today are much lower than they were at the time of this study and presage an eventual reduction (but not elimination) of lung cancer risk for those who continue to smoke cigarettes, especially among lifetime smokers of low-tar cigarettes.

description: The distribution of cigarette smoking (as well as of cigar and pipe smoking in men) by occupation was examined in over 800,000 men and women age 45-70 who were enrolled in the American Cancer Society's prospective study in 1982. Striking variations were seen for men--less striking variations for women. Smoking rates were significantly higher in groups exposed to a number of occupational hazards, compared to groups not so exposed. A considerable amount of variation is related to social class, but some individual occupations exhibit notably high (law enforcement) or low (clergy) smoking rates. This information can be quite useful in planning morbidity or mortality studies of specific occupational groups or in analyzing data from existing studies.

description: The consequences of climate change heavily influence the Mediterranean region. However, the Portuguese CO2 emission shows a decreasing tendency, the evolution of livestock and animal production have significantly increased its level in agriculture. The article investigates the role of the agricultural output and energy consumption in the environmental pollution in Portugal. It explores the short and long-run cointegration between carbon dioxide emissions and agricultural activities such as crop production, livestock production, and agricultural land use applying Autoregressive Distributed Lag (ARDL), Granger causality, Newey-West Standard Errors regression, as well as ARIMA model for the period of 1960-2015. The causality relation between CO2 emissions and agriculture is also analyzed. The Augmented Dickey-Fuller (ADF) unit root tests suggest that all variables are stationary. ARDL model demonstrates a long-run relationship between CO2 emissions, agriculture, and energy consumption. Results indicate that agricultural activities and energy use have a positive effect on environmental pollution; therefore, the Portuguese agriculture needs to achieve a higher level of sustainable development, with reducing the impact of animal husbandry and intensive crop production.

description: The past decade has seen great advances in our understanding of the role of noise in gene regulation and the physical limits to signaling in biological networks. Here, we introduce the spectral method for computation of the joint probability distribution over all species in a biological network. The spectral method exploits the natural eigenfunctions of the master equation of birth – death processes to solve for the joint distribution of modules within the network, which then inform each other and facilitate calculation of the entire joint distribution. We illustrate the method on a ubiquitous case in nature: linear regulatory cascades. The efficiency of the method makes possible numerical optimization of the input and regulatory parameters, revealing design properties of, e.g., the most informative cascades. We find, for threshold regulation, that a cascade of strong regulations converts a unimodal input to a bimodal output, that multimodal inputs are no more informative than bimodal inputs, and that a chain of up-regulations outperforms a chain of down-regulations. We anticipate that this numerical approach may be useful for modeling noise in a variety of small network topologies in biology.

description: Background: In 2005, the US Congress allocated $612 million for a national Safe Routes to School (SRTS) program to encourage walking and bicycling to schools. We evaluated the effectiveness of a Safe Routes to School Program (SRTS) in controlling pedestrian injuries among school-age children. Methods: Bayesian changepoint analysis of quarterly counts of pedestrian injuries among 5 to 19-year- old children in New York City between 2001 and 2010 during school-travel hours in census tracts with and without SRTS. Overdispersed Poisson modeling for difference in differences following the changepoint. Results: In SRTS-intervention census tracts, a change point in the quarterly counts of injuries was identified in the second quarter of 2008, which was consistent with the timing of the implementation of SRTS interventions. In census tracts with SRTS interventions, the estimated quarterly rates of pedestrian injury per 10,000 population among school-age children during school-travel hours were 3.47 (95% Credible Interval [CrI] 2.67, 4.39) prior to the changepoint, and 0.74 (95% CrI 0.30, 1.50) after the changepoint. There was no change in the average number of quarterly injuries in non-SRTS census tracts . Overdispersed Poisson modeling revealed that SRTS implementation was associated with a 44% reduction (95% Confidence Interval [CI] 87% decrease to 130% increase) in school-age pedestrian injury risk during school-travel hours. Conclusions: Bayesian changepoint analysis of quarterly counts of school-age pedestrian injuries correctly identified the timing of SRTS intervention in New York City. Implementation of the SRTS program in New York City appears to be effective in reducing school-age pedestrian injuries during school-travel hours.

description: Intensification of coffee (Coffea arabica) production is associated with increases in inorganic fertilizer application and decreases in species diversity. Both the use of organic fertilizers and the incorporation of trees on farms can, in theory, reduce nutrient loss in comparison with intensified practices. To test this, we measured nutrient concentrations in leachate at 15 and 100 cm depths on working farms. We examined (1) organically managed coffee agroforests (38 kg N ha−1 year−1; n = 4), (2) conventionally managed coffee agroforests (96 kg N ha−1 year−1; n = 4), and (3) one conventionally managed monoculture coffee farm in Costa Rica (300 kg N ha−1 year−1). Concentrations of nitrate (NO3 −-N) and phosphate (PO4 3−-P) were higher in the monoculture compared to agroforests at both depths. Nitrate concentrations were higher in conventional than organic agroforests at 15 cm only. Soil solutions collected under nitrogen (N)-fixing Erythrina poeppigiana had elevated NO3 −-N concentrations at 15 cm compared to Musa acuminata (banana) or Coffea. Total soil N and carbon (C) were also higher under Erythrina. This research shows that both fertilizer type and species affect concentrations of N and P in leachate in coffee agroecosystems.

description: The paper aims to analyse the comparative advantage patterns of agriculture in the Commonwealth of Independent States. It is relatively understudied in the literature, especially in Central Asia. Agriculture still plays an important role in the region but in a different way than before. Despite that, the majority of the CIS countries are net food importers. Based on the revealed comparative advantage (RCA) index, country-level analysis shows that Moldova, Kyrgyzstan and Armenia have the highest Balassa indices in the region, and Belarus, Ukraine and Azerbaijan are also having some comparative advantage. Product level analysis pointed out that the region’s major agricultural export products groups are cereals. It is important to emphasise that the top five product groups have high, between 3.0-4.4, RCA values. It implies that the regional trade structure is consistent with comparative advantages. However, stability and duration tests show that these are not persistent, since survival chances fell appreciably from 2000-2003 to 2012-2015.

description: INTRODUCTION; The belief that cancer risk can be reduced by lowering the tar yield of cigarettes has been developed from three basic observations: (1) many cancers exhibit a dose-response with respect to the number of cigarettes smoked per day, as shown in Figure 1 (Wynder & Stellman, 1977); (2) cancer risk decreases with number of years of smoking cessation (Fig. 2); (3) tumours can be produced quantitatively in animals using cigarette combustion products (Wynder & Hoffmann, 1967). Although quantitative relationships between cigarette smoking and cancer risk had been developed in both case-control and prospective studies in the 1950s and even earlier, epidemiological confirmation of a specific relationship with cigarette tar yield was not achieved consistently until the late 1960s. Since that time, differences in relative risk have been observed for at least four cancer sites: lung, larynx, oral cavity, and bladder. In this paper we review the data which have led to these conclusions, and discuss some of the similarities and differences in the studies.

description: Recent advances in imaging techniques and understanding of differences in the molecular biology of adipose tissue has rendered classical anatomy obsolete, requiring a new classification of the topography of adipose tissue. Adipose tissue is one of the largest body compartments, yet a classification that defines specific adipose tissue depots based on their anatomic location and related functions is lacking. The absence of an accepted taxonomy poses problems for investigators studying adipose tissue topography and its functional correlates. The aim of this review was to critically examine the literature on imaging of whole body and regional adipose tissue and to create the first systematic classification of adipose tissue topography. Adipose tissue terminology was examined in over 100 original publications. Our analysis revealed inconsistencies in the use of specific definitions, especially for the compartment termed “visceral” adipose tissue. This analysis leads us to propose an updated classification of total body and regional adipose tissue, providing a well-defined basis for correlating imaging studies of specific adipose tissue depots with molecular processes.

description: Herein we reported the design and synthesis of two series comprising twenty-two benzenesulfonamides that integrate the s-triazine moiety. Target compounds successfully suppressed the hCA IX, with IC50 ranging from 28.6 to 871 nM. Compounds 5d, 11b, 5b, and 7b were the most active analogues, which inhibited hCA IX isoform in the low nanomolar range (KI = 28.6, 31.9, 33.4, and 36.6 nM, respectively). Furthermore, they were assessed for their cytotoxic activity against a panel of 60 cancer cell lines following US-NCI protocol.

description: Self-reports of traumatic events are often used in clinical and epidemiologic studies. Nevertheless, research suggests combat exposure reports may be biased by posttraumatic stress disorder (PTSD) symptom severity, leading to an inflated dose-response relation between combat exposure and PTSD. The authors examined the consistency in combat exposure reports and their relation to PTSD symptoms in Vietnam Veteran American Legionnaires who responded to two mailed surveys (1984, 1998; N = 1,462). Combat exposure reports were highly reliable (test-retest correlation = 0.87). However, changes in exposure reporting were related to changes in PTSD symptoms, specifically reexperiencing symptoms. The effect size of the dose-response relation attributable to changes in reporting was smaller for continuous than categorical measures. Findings are discussed in relation to recent controversies over veterans' combat exposure reports.

Towards the event horizon -- the supermassive black hole in the Galactic Center

description: The center of our Galaxy hosts the best constrained supermassive black hole in the universe, Sagittarius A* (Sgr A*). Its mass and distance have been accurately determined from stellar orbits and proper motion studies, respectively, and its high-frequency radio, and highly variable near-infrared and X-ray emission originate from within a few Schwarzschild radii of the event horizon. The theory of general relativity (GR) predicts the appearance of a black hole shadow, which is a lensed image of the event horizon. This shadow can be resolved by very long baseline radio interferometry and test basic predictions of GR and alternatives thereof. In this paper we review our current understanding of the physical properties of Sgr A*, with a particular emphasis on the radio properties, the black hole shadow, and models for the emission and appearance of the source. We argue that the Galactic Center holds enormous potential for experimental tests of black hole accretion and theories of gravitation in their strong limits.

description: The large family of layered transition-metal dichalcogenides is widely believed to constitute a second family of two-dimensional (2D) semiconducting materials that can be used to create novel devices that complement those based on graphene. In many cases these materials have shown a transition from an indirect bandgap in the bulk to a direct bandgap in monolayer systems. In this work we experimentally show that folding a 1H molybdenum disulphide (MoS2) layer results in a turbostratic stack with enhanced photoluminescence quantum yield and a significant shift to the blue by 90 meV. This is in contrast to the expected 2H-MoS2 band structure characteristics, which include an indirect gap and quenched photoluminescence. We present a theoretical explanation to the origin of this behavior in terms of exciton screening.

Surface Plasmons and Nonlocality: a Simple Model

description: Surface plasmons on metals can concentrate light into sub-nanometric volumes and on these near atomic length scales the electronic response at the metal interface is smeared out over a Thomas-Fermi screening length. This nonlocality is a barrier to a good understanding of atomic scale response to light and complicates the practical matter of computing the fields. In this letter, we present a local analogue model and show that spatial nonlocality can be represented by replacing the nonlocal metal with a composite material, comprising a thin dielectric layer on top of a local metal. This method not only makes possible the quantitative analysis of nonlocal effects in complex plasmonic phenomena with unprecedented simplicity and physical insight, but also offers great practical advantages in their numerical treatment.

description: Newly measured optical absorption and photoluminescence spectra reveal substantial frequency shifts of both exciton and trion peaks as monolayer MoS2 is cooled from 363 K to 4 K. First-principles simulations using the GW-Bethe-Salpeter Equation approach satisfactorily reproduce these frequency shifts by incorporating many-electron interactions and the thermal expansion of the in-plane lattice constant. Studying these temperature effects in monolayer MoS2 is crucial for rectifying the results of room-temperature experiments with the previous predictions of zero-temperature-limit simulations. Moreover, we estimate that the thermal expansion coefficient of monolayer MoS2 is around 25% less than that of bulk counterpart by tracking the frequency shifts of the exciton or trion peaks in optical spectra. This may serve as a convenient way to estimate thermal expansion coefficients of general two-dimensional chalcogenides.

Organically Managed Coffee Agroforests Have Larger Soil Phosphorus but Smaller Soil Nitrogen Pools than Conventionally Managed Agroforests

description: The cultivation of crops in the presence of trees (agroforestry) and organic agriculture are management strategies thought to reduce nutrient losses to the environment and increase soil organic matter. Little is known, however, about the differences between organic and conventionally managed agroforests. This research examines how soil nutrient pools and mechanisms for nutrient retention may vary between these two different types of coffee agroforests. We determined variation in soil nutrient pools and nutrient retention capacity among (1) coffee farms in Costa Rica receiving mineral (conventional management) and organic inputs (organic management) and (2) different combinations of shade tree species. Soil nutrient pools and retention capacity were altered by fertilizer management. Soil nitrogen (N) and carbon (C) pools were significantly larger in conventional agroforests, but C:N ratios were similar among agroforests. Soil phosphorus (P) pools were significantly higher in organic agroforests. Overall, C and N concentrations were strongly positively correlated with oxalate-extractable aluminum concentrations. We did not observe many strong species effects; however, soil cation exchange capacity was higher under Coffea–Musa combinations than under Coffea and N-fixing Erythrina combinations. Thus, mechanisms are in place to promote nutrient retention in agroforestry systems, but these mechanisms can be altered by management practices with consequences for long-term nutrient storage.

description: We prove that the (real or complex) chromatic roots of a series-parallel graph with maxmaxflow Lambda lie in the disc |q-1| < (Lambda-1)/log 2. More generally, the same bound holds for the (real or complex) roots of the multivariate Tutte polynomial when the edge weights lie in the "real antiferromagnetic regime" -1 \le v_e \le 0. This result is within a factor 1/log 2 \approx 1.442695 of being sharp
Constant Trace Anomaly as a Universal Condition for the Chemical Freeze-Out

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: Finding out universal conditions describing the freeze-out parameters was a subject of various phenomenological studies. In the present work, we introduce a new condition based on constant trace anomaly (or interaction measure) calculated in the hadron resonance gas (HRG) model. Various extensions to the {\it ideal} HRG which are conjectured to take into consideration different types of interactions have been analysed. When comparing HRG thermodynamics to that of lattice quantum chromodynamics, we conclude that the hard-core radii are practically irrelevant, especially when HRG includes all resonances with masses less than $2~$GeV. It is found that the constant trace anomaly (or interaction measure) agrees well with most of previous conditions.

description: We consider the question of loop corrections (i.e. 1/N) in the vector model/higher spin duality following the recent work of Giombi and Klebanov. The purpose of this paper is to gain further more precise comparison between the two sides of the duality. For CFTs given by 3d O(N) or U(N) vector models we evaluate the leading and one loop partition functions in a variety of geometries. Our calculations are performed in the scheme of collective field theory which was seen in earlier studies to represent a bulk description of Vasiliev higher spin theory. The calculations presented provide data for comparison of small fluctuation determinants giving further evidence for the one-to-one bulk identification between the bi-local and the AdS picture. They also offer insight into the identification of coupling constants G and 1/N of the two descriptions for models based on O(N) symmetry.
