description: While the use of spin networks has greatly improved our understanding of the kinematical aspects of quantum gravity, the dynamical aspects remain obscure. To address this problem, we define the concept of a `spin foam' going from one spin network to another. Just as a spin network is a graph with edges labeled by representations and vertices labeled by intertwining operators, a spin foam is a 2-dimensional complex with faces labeled by representations and edges labeled by intertwining operators. Spin foams arise naturally as higher-dimensional analogs of Feynman diagrams in quantum gravity and other gauge theories in the continuum, as well as in lattice gauge theory. When formulated as a `spin foam model', such a theory consists of a rule for computing amplitudes from spin foam vertices, faces, and edges. The product of these amplitudes gives the amplitude for the spin foam, and the transition amplitude between spin networks is given as a sum over spin foams. After reviewing how spin networks describe `quantum 3-geometries', we describe how spin foams describe `quantum 4-geometries'. We conclude by presenting a spin foam model of 4-dimensional Euclidean quantum gravity, closely related to the state sum model of Barrett and Crane, but not assuming the presence of an underlying spacetime manifold.

description: While wealth distribution in the world is highly skewed and heavy-tailed, human talent - as the majority of individual features - is normally distributed. In a recent computational study by Pluchino et al [Talent vs luck: The role of randomness in success and failure, Adv. Complex Syst. 21 (03-04) (2018) 1850014], it has been shown that the combined effects of both random external factors (lucky and unlucky events) and multiplicative dynamics in capital accumulation are able to clarify this apparent contradiction. We introduce here a simplified version (STvL) of the original Talent versus Luck (TvL) model, where only lucky events are present, and verify that its dynamical rules lead to the same very large wealth inequality as the original model. We also derive some analytical approximations aimed to capture the mechanism responsible for the creation of such wealth inequality from a Gaussian-distributed talent. Under these approximations, our analysis is able to reproduce quite well the results of the numerical simulations of the simplified model in special cases. On the other hand, it also shows that the complexity of the model lies in the fact that lucky events are transformed into an increase of capital with heterogeneous rates, which yields a non-trivial generalization of the role of multiplicative processes in generating wealth inequality, whose fully generic case is still not amenable to analytical computations.

AtlantECO Deliverable D4.9 - Report on technology advancement
Creators: name: Robidart, Julie

Publisher: name: Zenodo
Year: 2024

description: Deliverable 4.9 reports on the technological innovations planned as part of Task 4.3.  These are based on two existing prototypes, which use in the marine environment has been previously demonstrated: (1) the Underwater Vision Profiler (UVP6-LP), and (2) the Robotic Cartridge Sampling Instrument (RoCSI, previously MAPS). The objectives of AtlantECO required further developments of these two devices to meet the needs of various science and industry stakeholders, and their deployment on a range of sampling platforms, such as a) aquaculture facilities, b) ships, sampling the underway system of a ship while towing the Continuous Plankton Recorder, c) in the deep sea for sustained operations, d) on free drifting Argo floats, and e) on moored sediment traps.

 

The Technology Readiness Level of four such applications are reported here. Two high-resolution imaging sensors (UVP6-LP) and an Argo float (NKE float) were purchased, and significant progress was made with the design and construction of free-drifting and moored instruments that combine sediment traps and the UVP6-LP. The RoCSI underwent extensive pressure testing and was upgraded for improved performance at depths up to 4500m. The upgrades increased ease of manufacturing and reduced the footprint by 100mm. This system was tested without any failure on RRS James Cook expedition 237 in August 2022 during transit, while towing the CPR.

description: Since the 1980s there has been a growing recognition of the significant risks associated with climate change. By 2007, the scientific evidence that anthropogenic greenhouse gas emissions were causing global warming was irrefutable. The Intergovernmental Panel on Climate Change released its Fourth Assessment Report which describes in great detail the biophysical and social impacts of climate change, some of which are already being experienced. Many argue that Australia is particularly vulnerable to the impacts of climate change. It is also widely acknowledged that as one of the highest per-capita emitters in the world, Australia has a particular responsibility to reduce its greenhouse gas emissions. However, despite this, Australia’s response to climate change has been largely inadequate, giving rise to a need for research into factors shaping this response. Research has identified the important role that discourses play in shaping perceptions of climate change and responses to the issue. As a complex and intangible issue, climate change needs to be represented through concepts, terms and the communication of scientific knowledge. Thus people’s understanding of climate change is mediated by the information available to them, the discourses within which it is embedded, and the ways that these discourses construct the issue.

description: We develop a calculus of surgery data, called bridged links, which involves besides links also pairs of balls that describe one-handle attachements. As opposed to the usual link calculi of Kirby and others this description uses only elementary, local moves(namely modifications and isolated cancellations), and it is valid also on non-simply connected and disconnected manifolds. In particular, it allows us to give a presentation of a 3-manifold by doing surgery on any other 3-manifold with the same boundary. Bridged link presentations on unions of handlebodies are used to give a Cerf-theoretical derivation of presentations of 2+1-dimensional cobordisms categories in terms of planar ribbon tangles and their composition rules. As an application we give a different, more natural proof of the Matveev-Polyak presentations of the mapping class group, and, furthermore, find systematically surgery presentations of general mapping tori. We discuss a natural extension of the Reshetikhin Turaev invariant to the calculus of bridged links. Invariance follows now - similar as for knot invariants - from simple identifications of the elementary moves with elementary categorial relations for invariances or cointegrals, respectively. Hence, we avoid the lengthy computations and the unnatural Fenn-Rourke reduction of the original proofs. Moreover, we are able to start from a much weaker ``modularity''-condition, which implies the one of Turaev. Generalizations of the presentation to cobordisms of surfaces with boundaries are outlined.

In particular, we define and investigate the best constants related to partial simplex inequalities. We also introduce and discuss some subclasses of $n$-distances defined by considering some properties. Finally, we discuss an interesting link between the concepts of $n$-distance and multidistance.

A strong dependence of this ratio with morphological type was found, ranging from typical values of ~15 percent for early spirals to up to ~50 percent for some late spirals. The extreme BCDs can have even higher percentages of their bolometric output re-radiated in the thermal infrared. Luminosity correction factors for the cold dust component are given for general use in converting far-infrared (FIR) luminosities derived from IRAS.

description: We consider Riemannian 4-manifolds $(X,g_X)$ with a Spin^c-structure and a suitable circle bundle $Y$ over $X$ such that the Spin^c-structure on $X$ lifts to a spin structure on $Y$. With respect to these structures a spinor $ϕ$ on $X$ lifts to an untwisted spinor $ψ$ on $Y$ and a U(1)-gauge field $A$ for the Spin^c-structure can be absorbed into a Kaluza-Klein metric $g_Y^A$ on $Y$. We show that irreducible solutions $(A,ϕ)$ to the Seiberg-Witten equations on $(X,g_X)$ for the given Spin^c-structure are equivalent to irreducible solutions $ψ$ of a Dirac equation with cubic non-linearity on the Kaluza-Klein circle bundle $(Y,g_Y^A)$. As an application we consider solutions to the equations in the case of Sasaki 5-manifolds which are circle bundles over Kaehler-Einstein surfaces.

description: Quantum memory -- the capacity to store and faithfully recover unknown quantum states -- is essential for quantum-enhanced technology. There is thus a pressing need for operationally meaningful means to benchmark candidate memories across diverse physical platforms. Here we introduce a universal benchmark distinguished by its relevance across multiple key operational settings, exactly quantifying (1) the memory's robustness to noise, (2) the number of noiseless qubits needed for its synthesis, (3) its potential to speed up statistical sampling tasks, and (4) performance advantage in non-local games beyond classical limits. The measure is analytically computable for low-dimensional systems and can be efficiently bounded in experiment without tomography. We thus illustrate quantum memory as a meaningful resource, with our benchmark reflecting both its cost of creation and what it can accomplish. We demonstrate the benchmark on the five-qubit IBM Q hardware, and apply it to witness efficacy of error-suppression techniques and quantify non-Markovian noise. We thus present an experimentally accessible, practically meaningful, and universally relevant quantifier of a memory's capability to preserve quantum advantage.

description: During the past several decades, observational data have shown a faster increase in hot temperature extremes than the change in mean temperature. Increasingly high extreme temperatures are expected to affect terrestrial ecosystem function. The ecological impact of hot extremes on vegetation production, however, remains uncertain across biomes in natural climatic conditions. In this study, we investigated the effects of hot temperature extremes on vegetation production by combining the MODIS enhanced vegetation index (EVI) data set and in situ climatic records during the period 2000 to 2009 from 12 long-term experimental sites across biomes and climate. Our results show that higher mean annual maximum temperatures (Tmax) greatly reduced grassland production, and yet enhanced forest production after removing the effect of precipitation. The relative decrease in vegetation production was 16% for arid grassland and 7% for mesic grassland, and the increase was 5% for forest. We also observed a significantly positive relationship between interannual aboveground net primary production (ANPP) and Tmax for the forest biome (R2 = 0.79, P < 0.001). This line of evidence suggests that hot temperature extremes lead to contrasting ecosystem-level responses of vegetation production between grassland and forest biomes. Given that many terrestrial ecosystem models use average daily temperature as input, predictions of ecosystem production should consider such contrasting responses to increasingly hot temperature extreme regimes associated with climate change.

description: Outbreaks of light leaf spot (Pyrenopeziza brassicae), a disease new to North America, occurred along with the diseases blackleg (Leptosphaeria spp.) and white leaf spot (Mycosphaerella capsellae) on Brassica crops in western Oregon. Disease symptoms in seed fields planted in the fall of 2013 were observed in the spring of 2014. Field surveys were conducted for disease during 2014 and 2015 to determine the geographic range of light leaf spot, blackleg, and white leaf spot within the Willamette Valley of western Oregon. Infected seed crops included turnip and oilseed rape in Benton, Lane, Linn, Marion, Polk, and Yamhill counties. New protocols that are more sensitive for detection of light leaf spot were developed for the pathogen population in the Pacific Northwest of the USA. Pyrenopeziza brassicae was detected when samples also contained L. maculans or M. capsellae. The test did not react with a range of other fungi evaluated. Sensitivity of the PCR protocol reported is robust at 10 pg of genomic DNA. Standard and real-time PCR screenings developed in this research increase sensitivity for detection of P. brassicae in affected Brassica hosts, which is critical for timely diagnosis and management of this newly-introduced disease in Brassica crops in the Pacific Northwestern region of the USA.

description: In this paper we study the effects of the coupling constant of the Chern-Simons modified gravity on some physical properties of black holes. The Hawking mass is one of the proposed definitions of quasilocal mass. We find that, for slowly rotating Chern-Simons black holes, the Hawking mass is independent of the coupling constant. Next, we show the dependence on the centre of mass energy, for two neutral colliding particles, of coupling constant and the rotation parameter. We also investigate energy extraction through Penrose process and find that the energy gain and efficiency of the Penrose process are independent of this coupling constant. Rotation of the polarization vector is also studied for dependence on the Chern-Simons coupling constant.

We prove the existence of local bases, called normal, in which the components of the derivations vanish along arbitrary paths. All such bases are explicitly described. The holonomicity of the normal bases is considered. The results obtained are applied to the important case of linear connections and their relationship with the equivalence principle is described. In particular, any gravitational theory based on tensor derivations which obeys the equivalence principle along all paths, must be based on a linear connection.

description: Objective: To investigate modifications of the Flemish Digit Triplet Test (DTT) to improve its efficiency, i.e. the use of a low-pass filtered noise and variable adaptive step sizes according to a digit scoring procedure, targeting different recognition probabilities. Design and study sample: Speech reception thresholds (SRT) were evaluated in terms of their test-retest reliability and correlation with pure tone averages (PTA) in a group of 68 adult participants with different degrees of hearing impairment. Results: The use of a low-pass filtered noise did not result in better test-retest reliability or an improved SRT-PTA correlation. Using digit scoring with adaptive step sizes parametrised to target a recognition probability of 79% (D79), corresponding to the recognition probability of the currently used DTT with triplet scoring and fixed adaptive step sizes of 2 dB, increased test-retest reliability. Lower recognition probabilities of 57 and 35% demonstrated worse reliability and worse SRT-PTA correlations. Conclusions: Given the increased test-retest reliability of D79, a similar reliability as for the currently used DTT could be obtained after considerably fewer trials, leading to a profit in test duration.

description: We report a new method to generate uniform large-scale optical focus arrays (LOFAs). By identifying and removing undesired phase rotation in the iterative Fourier-transform algorithm (IFTA), our approach rapidly produces computer-generated holograms of highly uniform LOFAs. The new algorithm also shows faster compensation of system-induced LOFA intensity inhomogeneity than the conventional IFTA. After just three adaptive correction steps, we demonstrate LOFAs consisting of $\mathcal{O}(10^3)$ optical foci with $> 98\ \%$ intensity uniformity.
Exponential Stellar Disks in Low Surface Brightness Galaxies: A Critical Test of Viscous Evolution
Creators: name: Bell, Eric F.
Publisher: name: arXiv
Year: 2002
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Viscous redistribution of mass in Milky Way-type galactic disks is an appealing way of generating an exponential stellar profile over many scale lengths, almost independent of initial conditions, requiring only that the viscous timescale and star formation timescale are approximately equal. However, galaxies with solid-body rotation curves cannot undergo viscous evolution. Low surface brightness (LSB) galaxies have exponential surface brightness profiles, yet have slowly rising, nearly solid-body, rotation curves. Because of this, viscous evolution may be inefficient in LSB galaxies: the exponential profiles, instead would give important insight into initial conditions for galaxy disk formation. Using star formation laws from the literature, and tuning the efficiency of viscous processes to reproduce an exponential stellar profile in Milky Way-type galaxies, I test the role of viscous evolution in LSB galaxies. Under the conservative and not unreasonable condition that LSB galaxies are gravitationally unstable for at least a part of their lives, I find that it is impossible to rule out a significant role for viscous evolution. This type of model still offers an attractive way of producing exponential disks, even in LSB galaxies with slowly-rising rotation curves.

description: In 1936, Weisskopf [K. Dan. Vidensk. Selsk. Mat. Fys. Medd. XIV (1936)] showed that for vanishing electric or magnetic fields the strong-field behavior of the one-loop Euler-Heisenberg effective Lagrangian of quantum electro dynamics (QED) is logarithmic. Here we generalize this result for different limits of the Lorentz invariants E⃗ 2−B⃗ 2 and B⃗ ·E⃗ . The logarithmic dependence can be interpreted as a lowest-order manifestation of an anomalous power behavior of the effective Lagrangian of QED, with critical exponents δ=e2/(12π) for spinor QED, and δS=δ/4 for scalar QED.

title: Guiding Stem Cells for Tissue and Organ Engineering: Clinical Grade Nanofiber Electrospinning for Recreation of the Optimal 3-Dimensional Extracellular Niche to Control Cellular Fate

subject: Recreation of the Optimal 3-Dimensional Extracellular Niche

description: We aimed to provide optimal and controlled growth mechanisms that determine the fate of cells by designing a novel polymeric, bio-functionalised 3-dimensional artificial Nanofibrous Extracellular Matrix (NF-ECM) that recapitulates the natural microenvironment of cells. We initially reviewed current cell-expansion methods, and clinically feasible protocols for tissue engineering applications. They are often based on conventional 2-dimensional tissue culture plates that usually require xenogenic coating substrates or feeder-cells to maintain their characteristics. Propagating cells in a 3-dimensional architecture, rather than in the conventional 2-dimensional flat monolayers, can be advantageous for many regenerative applications and biological or disease modelling studies. Furthermore, such 3-dimensional culture systems might be crucial in developing a bioreactor-based design that provides finely controlled environmental conditions that would reliably propagate 3-dimensional multilayered cell organisation or spheroids on a large scale. Furthermore, the ability to expand cells in the absence of animal-derived products is a necessary condition for clinical application.
The role of the state laboratories in multi-level climate policy research – considering India

description: The federal state of India is among the most vulnerable countries in the world with regard to climate change. Despite its low per capita emissions, India is the world’s third largest emitter of greenhouse gases. Accordingly, the country’s domestic climate policy requires substantial problem solving capacities to respond to these huge challenges involving different levels of government. This paper considers the question of whether comparative climate policy research should explore the role of India’s states in climate policy. Should state climate action in India be considered and even investigated through the “laboratories of experimentation” lens? By considering this question from a theoretical perspective, this paper aims at encouraging a more intense discussion of the topic. The paper presents a synopsis of the current state of research reviewing three strands of discussion: first, the laboratories of experimentation literature, second, comparative climate policy analysis dealing with the role of federal states in multi-level climate governance in the USA and Germany; and third, literature on the role of the Union states in India’s federal system. Moreover, to assess the scope for subnational state climate action, the institutional context of India’s multi- level climate governance structure is scrutinized. Using anecdotal examples of progress in Indian states, the paper calls attention to important areas of research which appear to hold key information but have not yet been adequately explored. It concludes that there are good reasons to include India’s states in comparative subnational climate policy research and, in particular, for considering interstate competition as a potential driver behind subnational climate action and energy policy in India.

description: Fractional-order elliptic problems are investigated in case of inhomogeneous Dirichlet boundary data. The boundary integral form is proposed as a suitable mathematical model. The corresponding theory is completed by sharpening the mapping properties of the corresponding potential operators. Also a mild condition is provided to ensure the existence of the classical solution of the boundary integral equation.

description: We have discovered an Ofpe/WN9 (WN11 following Smith et al.) star in the Sculptor spiral galaxy NGC 300, the first object of this class found outside the Local Group, during a recent spectroscopic survey of blue supergiant stars obtained at the ESO VLT. The light curve over a five-month period in late 1999 displays a variability at the 0.1 mag level. The intermediate resolution spectra (3800-7200 A) show a very close resemblance to the Galactic LBV AG Car during minimum. We have performed a detailed non-LTE analysis of the stellar spectrum, and have derived a chemical abundance pattern which includes H, He, C, N, O, Al, Si and Fe, in addition to the stellar and wind parameters. The derived stellar properties and the He and N surface enrichments are consistent with those of other Local Group WN11 stars in the literature, suggesting a similar quiescent or post-LBV evolutionary status.

description: Limewash, a mixture of lime putty and water used as a surface coating, has served as an architectural finish throughout the world for thousands of years, but little has been written about the use of this material in the United States. Historic sources cite the use of limewash in a number of different environments, including farm buildings, military buildings, and residences. However, it is not known whether limewash was commonly used throughout the United States or only in certain regions. This thesis attempts to answer that question through historical research by examining published materials that specifically mention limewash.

The history of publishing and the current availability of sources were major factors that defined the parameters of this research. Over 1,000 sources mentioning limewash were documented in order to examine spatial and temporal trends in limewash use. Most of the historic publications describe (then) new recipes for limewash intended to improve its performance. These recipes were documented and analyzed according to the additives listed. This thesis examines the various recipes and the intended effects of a number of additives.

Testing was performed to understand basic properties of limewash and additives and to ascertain the legitimacy of historic recipe claims. The tests utilized ASTM methods for adhesion, chalking resistance, and water-vapor transmission. The technical research, in combination with collection of historic paint recipes, seeks to answer questions about the historic use of limewash. Based on these findings, this thesis suggests appropriate uses for limewashes or historic limewash recipes based on testing rather than popular beliefs. This will allow preservationists and practitioners alike to be more informed when choosing a limewash for historic structures.
Sample Observed Effects: Enumeration, Randomization and Generalization

description: The widely used 'Counterfactual' definition of Causal Effects was derived for unbiasedness and accuracy - and not generalizability. We propose a Combinatorial definition for the External Validity (EV) of intervention effects. We first define the concept of an effect observation 'background'. We then formulate conditions for effect generalization based on samples' sets of (observed and unobserved) backgrounds. This reveals two limits for effect generalization: (1) when effects of a variable are observed under all their enumerable backgrounds, or, (2) when backgrounds have become sufficiently randomized. We use the resulting combinatorial framework to re-examine several issues in the original counterfactual formulation: out-of-sample validity, concurrent estimation of multiple effects, bias-variance tradeoffs, statistical power, and connections to current predictive and explaining techniques.
 Methodologically, the definitions also allow us to replace the parametric estimation problems that followed the counterfactual definition by combinatorial enumeration and randomization problems in non-experimental samples. We use the resulting non-parametric framework to demonstrate (External Validity, Unconfoundness and Precision) tradeoffs in the performance of popular supervised, explaining, and causal-effect estimators. We also illustrate how the approach allows for the use of supervised and explaining methods in non-i.i.d. samples. The COVID19 pandemic highlighted the need for learning solutions to provide predictions in severally incomplete samples. We demonstrate applications in this pressing problem.

description: Abstract. This paper describes the recommended solar forcing dataset for CMIP6 and highlights changes with respect to CMIP5. The solar forcing is provided for radiative properties, namely total solar irradiance (TSI), solar spectral irradiance (SSI), and the F10.7 index as well as particle forcing, including geomagnetic indices Ap and Kp, and ionization rates to account for effects of solar protons, electrons, and galactic cosmic rays. This is the first time that a recommendation for solar-driven particle forcing has been provided for a CMIP exercise. The solar forcing datasets are provided at daily and monthly resolution separately for the CMIP6 preindustrial control, historical (1850–2014), and future (2015–2300) simulations. For the preindustrial control simulation, both constant and time-varying solar forcing components are provided, with the latter including variability on 11-year and shorter timescales but no long-term changes. For the future, we provide a realistic scenario of what solar behavior could be, as well as an additional extreme Maunder-minimum-like sensitivity scenario. This paper describes the forcing datasets and also provides detailed recommendations as to their implementation in current climate models.
