Addressing SHIP in the incoming 3rd generation CSP-TES: the COOPERANT concept
Creators: name: Idener (Spain)
Publisher: name: Zenodo
Year: 2025
Subjects: subject: Concentrated solar power
subject: Solar energy
subject: Energy storage

description: The forthcoming third-generation concentrated solar power (CSP) plants will be able to operate at high temperatures exceeding 600 ºC, limiting the current conventional plants. This disruptive advancement unlocks new configurations that includes the integration of high-temperature thermal energy storage (TES) systems. It also constitutes a breakthrough in the decarbonisation of the industrial and energy sectors since it makes possible the alignment with European Net Zero 2050 and the SET Plan goals.

This new CSP generation must deal with crucial challenges for its future commercial implementation regarding material availability, system design and performance limitations. To address these challenges, new lines of research and development must focus on developing advanced materials with great corrosion and erosion resistance for components, reducing costs for advanced materials and critical components in cycle power blocks, and cost-effective and reliable systems for high-temperature CSP-TES integration.

The COOPERANT project introduces a new ground-breaking concept that incorporates cutting-edge technological solutions. Firstly, the novel COOPERANT CSP-TES prototype is designed for higher efficiency power cycles (>42%) and high temperatures (>1000ºC), paving dispatchable and uninterrupted generation. Secondly, COOPERANT-TOOL includes advanced artificial intelligence (AI) that will power the energy management of this CSP-TES integration. Finally, COOPERANT TRANSFER develops an innovative Open Science plan with strong involvement of an industrial Stakeholder Replicability Board for clustering, networking and implementation of synergetic actions within the European industry sector.

The COOPERANT first-of-its-kind prototype showcases a high-performance volumetric solar receiver with custom-designed cellular morphology coupled with a novel, compact, sustainable and cost-effective TES system with a cascade approach. This hybrid packed-bed TES combines sensible and latent materials with great heat capacities (600 kWh/m3) able to operate at temperatures up to 1300ºC. Additionally, advanced AI tools (deep learning reinforcement and multi-objective optimization) facilitate energy management easing the hybridization with other RES as photovoltaics. This opens possibilities for providing CO2-free electricity and high-temperature heat for industrial applications in the cement sector (calcination, clinker formation) and in steelmaking processes (heat treatment, quenching, melting). It also promotes the decarbonisation of the chemical and pharmaceutical industry and the production of solar fuels (syngas and H2).

description: Systemic drug delivery via the pulmonary route has a critical limitation because dose uniformity is strongly dependent upon patient inhalation technique. The most frequent and critical errors in inhalation technique are overly forceful inspiration and insufficient breath-holding. In this study, response surface methodology was used with an in silico whole lung particle deposition model for bolus administration to investigate whether varying the inhaled drug particle size could reduce the dependence of deposition upon flow rate and/or breath-holding duration. The range of particle aerodynamic diameters studied was 0.1-10 µm for flow rates between 500-2000 mL/s and breath-holding duration between 0-15 seconds. Comparison with published experimental data showed that this modelling approach can accurately predict the lung deposition. The simulation results indicated that the deposition of particles with aerodynamic diameter in the range of 0.1-1.5 µm should be minimally affected by flow rate over the 500-2000 mL/s range. There was found to be no particle size whose deposition was completely independent of breath-holding duration. The smallest particles, whose deposition is diffusion-driven, were found to be the least sensitive to breath-holding time, but this size is of limited practical use. On the other hand, the simulations indicated that particles with a 1.5 µm diameter would provide acceptable consistency in dose reaching the acini region when the breath-holding duration was greater than 10 seconds. It is hoped that this finding could provide a means of improving dose uniformity for systemic delivery via the pulmonary route by facilitating simplified patient instructions.
Computing Tails of Compound Distributions Using Direct Numerical Integration

description: An efficient adaptive direct numerical integration (DNI) algorithm is developed for computing high quantiles and conditional Value at Risk (CVaR) of compound distributions using characteristic functions. A key innovation of the numerical scheme is an effective tail integration approximation that reduces the truncation errors significantly with little extra effort. High precision results of the 0.999 quantile and CVaR were obtained for compound losses with heavy tails and a very wide range of loss frequencies using the DNI, Fast Fourier Transform (FFT) and Monte Carlo (MC) methods. These results, particularly relevant to operational risk modelling, can serve as benchmarks for comparing different numerical methods. We found that the adaptive DNI can achieve high accuracy with relatively coarse grids. It is much faster than MC and competitive with FFT in computing high quantiles and CVaR of compound distributions in the case of moderate to high frequencies and heavy tails.

description: Understanding charge transport in organic semiconductors in large electric fields is relevant to many applications. We present transport measurements in organic field-effect transistors based on poly(3-hexylthiophene) and 6,13-bis(triisopropyl-silylethynyl) pentacene with short channels, from room temperature down to 4.2 K. Near 300 K transport in both systems is well described by thermally assisted hopping with Poole-Frenkel-like enhancement of the mobility. At low temperatures and large gate voltages, transport in both materials becomes nearly temperature independent, crossing over into field-driven tunneling. These data, particularly in TIPS-pentacene, show that great caution must be exercised when considering more exotic (e.g., Tomonaga-Luttinger Liquid) interpretations of transport.

description: We explore topological excitations in a spin-1 Bose-Einstein condensate subjected to an in-plane sinusoidally varying magnetic field and Rashba spin-orbit coupling (SOC). In the absence of SOC, the periodic magnetic field induces vortex-anti-vortex structures in the $\ket{F=1, m_F=\pm1}$ condensates at saddle-points, such that the net topological charge remains zero. The introduction of Rashba SOC breaks the system's symmetry, leading to non-conservation of overall angular momentum in the spin-1 condensate. This anisotropy results in the emergence of certain skyrmion spin textures. We provide a comparative study for various in-plane magnetic field configurations while keeping the SOC strength constant. Our numerical simulations within the mean-field framework reveal the potential to engineer diverse topological excitations controlled by the interplay between spin-orbit coupling and in-plane magnetic field in a spinor condensate.

Approximating maximum independent set on Rydberg atom arrays using local detunings

description: Rydberg atom arrays operated by a quantum adiabatic principle are among the most promising quantum simulating platforms due to their scalability and long coherence time. From the perspective of combinatorial optimization, they offer an efficient solution for an intrinsic maximum independent set problem because of the resemblance between the Rydberg Hamiltonian and the cost function of the maximum independent set problem. In this study, a strategy is suggested to approximate maximum independent sets by adjusting local detunings on the Rydberg Hamiltonian according to each vertex's vertex support, which is a quantity that represents connectivity between vertices. By doing so, the strategy successfully reduces the error rate three times for the checkerboard graphs with defects when the adiabaticity is sufficient. In addition, the strategy decreases the error rate for random graphs even when the adiabaticity is relatively insufficient. Moreover, it is shown that the strategy helps to prepare a quantum many-body ground state by raising the fidelity between the evolved quantum state and a 2D cat state on a square lattice. Finally, the strategy is combined with the non-abelian adiabatic mixing and this approach is highly successful in finding maximum independent sets compared to the conventional adiabatic evolution with local detunings.
Folic acid nutritional status of British Columbia Indian populations
Creators: name: Porritt, Barbara
Publisher: name: University of British Columbia

description: Recent studies suggest that folic acid nutritional status may be poor among Canadian Indians, particularly among those living in isolated areas. However the prevalence and causes of folic acid deficiency have not been assessed. The present study was conducted in order to assess the magnitude of the problem among British Columbia Indians and to examine the possible relationship between low dietary intakes of folic acid and the occurrence of low blood folate values. Using a 24-hour diet recall, dietary folate intakes were estimated at four relatively isolated Indian reserves (106 subjects) and at three reserves adjacent to urban centres (144 subjects). A more detailed study, involving estimation of dietary folate intake, measurement of serum and red blood cell folate, and examination of related hematological parameters was undertaken at one isolated reserve (Fort Ware, 28 subjects) and two non-isolated reserves (Necoslie and Sechelt, 63 subjects) as well as at a school residence (70 children, age 6 to 16 years). Meal samples were collected and assayed for folic acid, in order to verify the recall calculations. Results indicate that calculated and assayed folate values are similar and are significantly correlated (r=.9694). Total folate consumption is significantly higher at non-isolated reserves than at isolated reserves, and males consume significantly more folic acid than do females. Dietary folic acid intake is higher at the residence than at the reserves. Serum folate values are significantly correlated with dietary folate intake. Serum values are lower at Fort Ware than at Necoslie and Sechelt. Children living on reserves have lower serum folate values than do children living in residence, and have a larger proportion of children classified as "at risk". On the basis of red cell folate values, 16 to 45% of the subjects at the three reserves are classified as "at risk", however, no evidence of megaloblastic anemia is indicated from the hematological examinations. It is concluded that many individuals are either bordering on or are deficient with respect to folic acid. This appears to be a more serious problem at isolated reserves than at those adjacent to urban centres and it is suggested that this is a consequence of the availability, variety and selection of foods.

description: The rapid development of brain-inspired computing requires new artificial components and architectures for its hardware implementation. In this regard, memristive devices emerged as potential candidates for artificial synapses because of their ability to emulate the plasticity of the biological synapses. In this work, the synaptic behavior of the TiN/La2NiO4+δ/Pt memristive devices based on thermally annealed La2NiO4+δ films is thoroughly investigated. Using electron energy loss spectroscopy, we show that annealing using reducing (Ar) or oxidizing (O2) atmospheres affects the interstitial oxygen content (δ) in the La2NiO4+δ films. Electrical characterization shows that both devices exhibit long-term potentiation/depression and spike-timing-dependent plasticity, which makes them suitable for neuromorphic applications. At the same time, the Ar annealed TiN/La2NiO4+δ/Pt device demonstrates non-volatile properties with low energy consumption during the learning process. On the other hand, in the O2 annealed TiN/La2NiO4+δ/Pt device the resistive switching behavior is more volatile and requires more energy for synaptic learning. Finally, the simulation tools show that spiking neural network architectures with unsupervised learning rules based on the experimental data achieve high inference accuracy in the digit recognition task, which proves the potential of TiN/La2NiO4+δ/Pt devices for artificial synapse applications.

description: This paper presents a novel stabilized mixed material point method (MPM) designed for the unified modeling of free-surface and seepage flow. The unified formulation integrates the Navier-Stokes equation with the Darcy-Brinkman-Forchheimer equation, effectively capturing flows in both non-porous and porous domains. In contrast to the conventional Eulerian computational fluid dynamics (CFD) solver, which solves the velocity and pressure fields as unknown variables, the proposed method employs a monolithic displacement-pressure formulation adopted from the mixed-form updated-Lagrangian finite element method (FEM). To satisfy the discrete inf-sup stability condition, a stabilization strategy based on the variational multiscale method (VMS) is derived and integrated into the proposed formulation. Another distinctive feature is the implementation of blurred interfaces, which facilitate a seamless and stable transition of flows between free and porous domains, as well as across two distinct porous media. The efficacy of the proposed formulation is verified and validated through several benchmark cases in 1D, 2D, and 3D scenarios. Conducted numerical examples demonstrate enhanced accuracy and stability compared to analytical, experimental, and other numerical solutions.

description: The bistability of the core magnetization of nano-scaled magnets with a magnetic vortex configuration has great potential for data storage applications. To exploit this, reliable switching between the two possible states is needed. Time resolved x-ray microscopy was used to study the response of the vortex core to excitation pulses at sub-ns timescales and image the vortex core switching. A reliable switching process by coherent excitation with leading and trailing edges of in-plane magnetic field pulses was found and compared with micromagnetic simulations.

description: Chronic heart failure (CHF) is a syndrome accompanied by a decrease in cardiac output or an increase in heart filling pressure due to structural or functional disorders of the myocardium. CHF remains an important problem in modern medicine, being one of the main causes of hospitalization and mortality. It affects more than 64 million people worldwide. In Europe, the prevalence of CHF among all functional classes according to the classification of the New York Heart Association (NYHA) is 7%, and for grades III-IV — 2.1%. More than 600,000 patients over the age of 65 are discharged with CHF every year, with a 25% chance of re-hospitalization within 30 days and 70% a year after discharge.

To do so we partition the contributions of the heat transfer, the work done, and the heat flux vector between the longitudinal and transverse temperatures. With shockwave boundary conditions time-dependent solutions of these equations converge to give stationary shockwave profiles. The profiles include anisotropic temperature and can be fitted to molecular dynamics results, demonstrating the utility and simplicity of a two-temperature description of far-from-equilibrium states.

description: Motivated by the recent realization of space-borne Bose-Einstein Condensates (BECs) under micro-gravity conditions, we extend the understanding of ultracold dipolar bosonic gases by exploring their behavior in a novel trapping configuration known as the ``bubble trap" topology. Utilizing the three-dimensional numerical simulations within the extended Gross-Pitaevskii framework, we unveil diverse ground state phases in this static curved topology. Subsequently, we investigate the influence of rotation on a dipolar BEC confined to the surface of a spherical bubble. Our findings reveal that the rotation of a bubble trap at certain rotation frequencies can modify the effective local dipole-dipole interaction strength, leading to the induction of supersolidity and the formation of quantum droplets. In addition, we demonstrate that a bubble trap can sustain high circulation, with the flow persisting for a longer time. Significantly, adjusting the rf detuning parameter allows the condensate to achieve hypersonic velocity. Finally, we also explore the impact of drastic change in the topological nature of the trap on the rotating dipolar BEC, transitioning from a filled shell trap to a bubble trap and vice versa. Based on the results of the topological transition, we propose a dynamic protocol to drive the interacting atomic gas into the quantum Hall regime.

description: The analysis of the Cosmic Microwave Background (CMB) data acquired by the Atacama Cosmology Telescope (ACT) and the large-scale ($\ell\lesssim1300$) Planck Telescope show a preference for the Early Dark Energy (EDE) theory, which was set to alleviate the Hubble tension of the $Λ$ Cold Dark Matter ($Λ$CDM) model by decreasing the sound horizon $r_{s}$, and gives $H_{0} \approx 72$ km s$^{-1}$ Mpc$^{-1}$. However, the EDE model is commonly questioned for exacerbating the $σ_8$ tension on top of the $Λ$CDM model, and its lack of preference from the late-time matter power spectrum observations, e.g., Baryon Oscillation Spectroscopic Survey (BOSS). In light of the current obscurities, we inspect if the high redshift galaxy abundance, i.e., Stellar Mass Function/Density (SMF/SMD) and Luminosity Function (LF), can independently probe the EDE model. Our result shows that, compared to $Λ$CDM, the EDE model prediction at $z>10$ displays better consistency with the unexpectedly high results observed by the James Webb Space Telescope (JWST). At lower redshift, the EDE model only fits the most luminous/massive end, with the majority of the data presenting better consistency with $Λ$CDM, implying that adding an extra luminosity/mass-sensitive suppression mechanism of the galaxy formation is required for EDE to explain all data around $z\sim7-10$.

Polifonia nelle antologie di W.B. Yeats: il dialogo complesso tra folklore e letteratura

description: Compiling and publishing a folk narrative anthology is anything but a trivial, neutral undertaking, especially if this is set in a period of great literary and cultural fervour as was the late XIX century in Ireland. With his Fairy and Folk Tales of the Irish Peasantry (1888) and Irish Fairy Tales (1892) W.B. Yeats gives rise to a complex narrative system in which, necessarily, heterogeneous, if not contradictory voices and points of view meet, and the editor’s task is precisely to make this polyphony work. In the anthologized stories one observes the overlapping and interweaving of narrative levels that reflect a wide range of ideas, beliefs, knowledge, values from which emerges a picture of cultural and social Irish stratification, as well as of relationships being established between the lower and ruling classes, folklore and literature, orality and literacy. After examining in general the folk narrative anthology as an inherently polyphonic object, I propose a specific reading of the Yeatsian collections, focusing in particular on the paratextual apparatus, namely on the borders, the frames of the text – where interactions take place between several narrative levels, as well as historical, cultural, and social meanings – in order to identify, if possible, elements of unity and coherence in a system constitutively plurivocal and open to a variety of interpretations.

description: As our ability to make more sensitive measurements increases, we begin to reach for the ultimate measurement sensitivity: a single entity. Mass spectrometry and fluorescence-based methods exist for single entity studies, and through these the intriguing effects of confinement begin to be observed. These mass spectrometry and fluorescence-based techniques are however, often destructive, which precludes measurements over time. The advent of nanoelectrochemical methods, however, allows for the creation of tools that can make measurements inside of confined volumes—a droplet, a cell, etc.—over extended periods of time. While most nanoelectrochemical methods are based on amperometry or voltammetry, potentiometry allows for minimal perturbation of the system’s homeostasis by passing negligible current. To overcome many of the issues involved in these other methods, we design potentiometric tools that can be easily miniaturized to fit within single entities, particularly within single cells. These tools include enzymatic biosensors designed to be minimally influenced by the cell’s O2 or NAD+ levels, as well as a novel reference electrode that can be made to be very low leakage or completely leakless to avoid contamination of the cell by the reference electrode’s internal filling solution. Both of these tools are designed such that they are easily modified to suit a number of different applications, including for use inside non-aqueous solutions.

Here I summarise the status of the project and plans for the future, including expectations for sensitivity and science targets as well as the status of the site search and technological developments.

title: Spectroscopic analysis of roads at traffic speed
Creators: name: Bowden, Hannah

description: Currently in the UK road surfaces are monitored visually for defects and signs of failure. However the time between detection of road degradation (e.g cracks and potholes), and complete failure of the road surface is very short. Therefore rejuvenation techniques that may initially be favourable are ineffective and a total resurfacing is the required. It is therefore of interest to be able to predict the condition of the road surface in an attempt to better plan and schedule the rejuvenation techniques and effectively save money, and maintain safer, more comfortable roads. Road surfaces can fail in many different ways as a result of many different factors. The chemical oxidation of bitumen, the main binding component of asphalt road surfaces, is a major contributor to the age hardening and ultimate failure of the roads. There is an abundance of research in the literature that has identified the use of infrared spectroscopy as an analytical technique to monitor the oxidation of bitumen and therefore this research looks to explore the feasibility of utilising this technique as a detection method for the oxidation of bitumen within asphalt road surfaces. Diffuse reflectance infrared spectroscopy has been utilised in this project in order to identify any possible oxidation product markers present within the infrared spectra collected. The project initially involved ageing bitumen artificially and naturally and analysing the changes with Diffuse Reflectance Infrared Fourier Transform (DRIFT) spectroscopy. Once chemical oxidation markers had been identified the project then focused upon the artificial and natural ageing of asphalt. The same chemical markers were identified and quantified with regards to the solar exposure. Mechanical testing of bitumen and asphalt has also been carried out in order to compare the chemical changes to standardised physical property changes that correspond to deterioration of the bitumen. The project also develops a method for analysis of real road surfaces outside of the laboratory. A trolley has been built in order to support a handheld spectrometer close to the surface for data collection. A number of different roads have been analysed in this way. This report will outline the results obtained from these experiments and the data analysis. The recommendations and future work are also included within this report.

description: In recent years, neural network-based classification has been used to improve data analysis at collider experiments. While this strategy proves to be hugely successful, the underlying models are not commonly shared with the public and rely on experiment-internal data as well as full detector simulations. We show a concrete implementation of a newly proposed strategy, so-called Classifier Surrogates, to be trained inside the experiments, that only utilise publicly accessible features and truth information. These surrogates approximate the original classifier distribution, and can be shared with the public. Subsequently, such a model can be evaluated by sampling the classification output from high-level information without requiring a sophisticated detector simulation. Technically, we show that Continuous Normalizing Flows are a suitable generative architecture that can be efficiently trained to sample classification results using Conditional Flow Matching. We further demonstrate that these models can be easily extended by Bayesian uncertainties to indicate their degree of validity when confronted with unknown inputs by the user. For a concrete example of tagging jets from hadronically decaying top quarks, we demonstrate the application of flows in combination with uncertainty estimation through either inference of a mean-field Gaussian weight posterior, or Monte Carlo sampling network weights.

description: Our calculation shows that negative refractive index (NRI), which was known to exist only in metamaterials in the past, can be found in Dirac semimetals (DSM). Electrons in DSM have zero effective mass and hence the system carries no nominal energy scale. Therefore, unlike those of ordinary materials, the electromagnetic responses of the electrons in DSM will not be overwhelmed by the physical effects related to electron mass. NRI is induced by the combination of the quantum effect of vacuum polarization and its finite temperature correction which is proportional to $T^4$ at low temperature. It is a phenomenon of resonance between the incident light and the unique structure of Dirac cones, which allows numerous states to participate in electron-hole pair production excited by the incident light with similar dispersion relation to that of Dirac cones. NRI phenomenon of DSM manifests in an extensive range of photon frequency and wave number and can be observed around giga Hertz range at temperature slightly higher than room temperature.

description: We study a new inflation potential in the framework of the Randall-Sundrum type 2 Braneworld model. Using the technic developped in(Phys. Rev. D75, 123504 (2007).1), we consider both an monomial and a new inflation potentials and apply the Slow-Roll approximation in high energy limit, to derive analytical expression of relevant perturabtion spectrum. We show that for some values of the parameter n of the potential, we obtain an perturbation spectrum wich present a good agreement with recent WMAP5 observations.

title: Coherence in typeface design: visual similarity of characters in Cyrillic, Devanagari, and Latin
Creators: name: Brezina, David
Publisher: name: University of Reading
Year: 2019

description: This thesis explores the visual similarity that underlies the coherence in the design of individual typefaces. Typeface designers aim to achieve a unifying coherence in their typefaces, so that characters can be identified individually as well as belonging together giving rise to an overall style. The objective is to determine whether the coherence perceived by readers differs from the coherence intended by designers. The research is cross-disciplinary, combining empirical studies of readers’ perceptions with a computational model that is based on relevant typeface design knowledge. Character similarity is studied in multiple different typefaces (fonts) intended for continuous reading in Cyrillic, Devanagari, and Latin scripts. The studies were conducted online to collect a large number of responses. The participants were presented with a sequence of character triplets. They were asked to identify the odd one out in each of these triplets judging by their visual similarity, thus making a statement about the similarity of the two complementary characters. This method studies the similarity in context, which provides more refined details about participants’ similarity judgements. The model interprets characters using two kinds of features: more specific parts and more general roles. The model learns the relative saliences of these features from a subset of the data collected in the studies. This allows the model to predict participants’ responses to the triplets from the studies and for other, unseen triplets. Additionally, the model can provide explanations of the criteria participants used in their similarity judgements and can generate similarity matrices. The model achieved high scores when predicting response probabilities and identifying the overall odd ones out. A view of coherence that is supported by readers’ perception can be used to assist designers in their creative process, help with fonts’ quality assessments, and contribute to readability research and multi-script typography.

description: We study the supersymmetry enhancement of nonrelativistic limits of the ABJM theory for Chern-Simons level $k=1,2$. The special attention is paid to the nonrelativistic limit (known as `PAAP' case) containing both particles and antiparticles. Using supersymmetry transformations generated by the monopole operators, we find additional 2 kinematical, 2 dynamical, and 2 conformal supercharges for this case. Combining with the original 8 kinematical supercharges, the total number of supercharges becomes maximal: 14 supercharges, like in the well-known PPPP limit. We obtain the corresponding super Schrödinger algebra which appears to be isomorphic to the one of the PPPP case. We also discuss the role of monopole operators in supersymmetry enhancement and partial breaking of supersymmetry in nonrelativistic limit of the ABJM theory.
