description: Cellular automata can show well known features of quantum mechanics, such as a linear updating rule that resembles a discretized form of the Schrödinger equation together with its conservation laws. Surprisingly, a whole class of "natural" Hamiltonian cellular automata, which are based entirely on integer-valued variables and couplings and derived from an Action Principle, can be mapped reversibly to continuum models with the help of Sampling Theory. This results in "deformed" quantum mechanical models with a finite discreteness scale $l$, which for $l\rightarrow 0$ reproduce the familiar continuum limit. Presently, we show, in particular, how such automata can form "multipartite" systems consistently with the tensor product structures of nonrelativistic many-body quantum mechanics, while maintaining the linearity of dynamics. Consequently, the Superposition Principle is fully operative already on the level of these primordial discrete deterministic automata, including the essential quantum effects of interference and entanglement.

description: We consider the Bayesian optimal filtering problem: i.e. estimating some conditional statistics of a latent time-series signal from an observation sequence. Classical approaches often rely on the use of assumed or estimated transition and observation models. Instead, we formulate a generic recurrent neural network framework and seek to learn directly a recursive mapping from observational inputs to the desired estimator statistics. The main focus of this article is the approximation capabilities of this framework. We provide approximation error bounds for filtering in general non-compact domains. We also consider strong time-uniform approximation error bounds that guarantee good long-time performance. We discuss and illustrate a number of practical concerns and implications of these results.

description: We suggest an algorithm to automatically identify changes in the production of DC power that may indicate malfunctions of two-axis trackers as well as of photovoltaic modules connected to the same string. The algorithm uses DC current sensor data exclusively. No information about the specific characteristics of the PV power plant is needed. The algorithm is sensitive to relative changes in the power production as little as 1% while at the same time being nonsensitive against weather based noise like cloud shadows. The evaluation shows a detection rate of up to 90% while keeping the rate of false alarms low (about 12%). Our method can also be applied as-is to other monitoring tasks like temperature anomalies in inverters (failed cooling) or disturbances in the synchronicity of AC current phases in transformers.

description: The optical properties of nonimaging 3D-CPC solar concentrators, irradiated by collimated beams, have been investigated by using original simulation methods. These methods were not limited to investigate properties directly related to the practical application of the concentrators, but were also used to study any detailed aspect related to their transmission, reflection and absorption characteristics. We have investigated, therefore, besides to the flux transmitted to the receiver, also the flux back reflected and the flux absorbed on the internal wall of the concentrator. The main results of the simulations were: efficiency of transmission, reflection and absorption, average number of reflections on the internal wall of both transmitted and reflected rays, their angular divergence at the output and at the input of the concentrator, respectively, distribution of flux on the receiver and on the internal wall surface. The above mentioned theoretical investigations on 3D-CPC solar concentrators are aimed at improving the knowledge of their optical properties, expanding their application field and opening new perspectives to the methods of their characterization. The presented methods can be fruitfully applied to any other type of solar concentrator.
Gilles Deleuze and the search for “sense” in the stories of illness: a methodological proposal
Creators: name: Consorti, Fabrizio
Publisher: name: Tutor
Year: 2023

description: Introduction: this article briefly summarises some of the concepts in the Logic of Sense, by Gilles Deleuze and proposes a method of structural analysis of a text of illness narrative. Methods: the main concepts are the distinction of Things from the Events, the importance of the surface separating them, the concepts of problem and of paradoxical instance. A eight step process of textual analysis is proposed. Results: A worked example clarifies the steps of the method and some suggestions for the educational use of this kind of textual analysis is provided. Discussion: this is a useful approach when the focus is on analysing the social discourse and social structures that can be a source of oppression for some social groups, but also to increase the awareness about the way in which sense is produced in verbal production.

description: New Zealand is exploring the possibility of exporting hydrogen produced from its abundant renewable energy resources. A key question that arises is what is the “best” way to transport hydrogen internationally at large scale. There is no simple answer to this question, as the “best” option will depend on the customer and their intended usage, the efficiency and safety of the supply chain and the availability of critical infrastructure. In this paper, we discuss the results of our recent study [1] that explored the capital cost and energy efficiency considerations of the three most prominent potential hydrogen carriers: liquid hydrogen, ammonia and the toluene/methylcyclohexane system (MCH). Capital costs for a nominal power draw of 600 MW were developed for the electrolyser and carrier formation plants, and for the overseas decomposition plant in the case of the MCH option. Despite significant differences in the amount of hydrogen produced, the overall capital envelopes were remarkably consistent (~$2 billion). The contributions of the cost of electricity (at a net cost of $65/MWh) and levelized cost of capital indicated that liquid hydrogen could potentially be the most cost effective solution, although it requires the construction of new shipping vessels. Ammonia for direct use is comparable, and has no infrastructure barriers, but ammonia decomposition and MCH dehydrogenation are energy intensive and result in higher costs. The presentation will develop this study further through the addition of sensitivity analysis. [1] Hinkley et al., IJHE, 47(85), 35959-35975, https://doi.org/10.1016/j.ijhydene.2022.08.192

description: This paper provides a recommended method for evaluating the AC capacity of a photovoltaic (PV) generating station. It also presents companion guidance on setting the facilitys capacity guarantee value. This is a principles-based approach that incorporates plant fundamental design parameters such as loss factors, module coefficients, and inverter constraints. This method has been used to prove contract guarantees for over 700 MW of installed projects. The method is transparent, and the results are deterministic. In contrast, current industry practices incorporate statistical regression where the empirical coefficients may only characterize the collected data. Though these methods may work well when extrapolation is not required, there are other situations where the empirical coefficients may not adequately model actual performance.This proposed Fundamentals Approach method provides consistent results even where regression methods start to lose fidelity.

description: Galilean Genesis is generically plagued with a strong coupling problem, but this can be avoided depending on the hierarchy between a classical energy scale of genesis and a strong coupling scale. In this paper, we investigate whether or not the models of Galilean Genesis without the strong coupling problem can explain the statistical properties of the observed CMB fluctuations based on two unified frameworks of Galilean Genesis. By focusing on the class in which the propagation speeds of the scalar and tensor perturbations are constant, we show that the models avoiding strong coupling and allowing a slightly red-tilted scalar power spectrum suffer from an overproduction of a scalar non-Gaussianity.

description: The use of light concentrator systems has been proved to be an effective means of reducing the electricity costs produced by photovoltaics; in fact with this technology the area of the photovoltaic cell used is reduced, compared with a flat-photovoltaic application, thanks to the introduction of less expensive lenses and mirrors. The aim of this paper is the description and realization of several outdoor measurement apparatuses for an overall outdoor characterization of cells and lenses for photovoltaic concentration systems; in this way we can determine the electrical and the optical characteristics of concentration systems using as light source directly the sun light. Therefore the problem to reproduce a light flux over extensive areas with the same spatial divergence of the sun light, very important problem to face for indoor measurement apparatuses, it is overcome.

description: We use high-precision kinematic and lensing measurements of the total mass profile of the dynamically relaxed galaxy cluster MACS J1206.2-0847 at $z=0.44$ to estimate the value of the ratio $η=Ψ/Φ$ between the two scalar potentials in the linear perturbed Friedmann-Lemaitre-Robertson-Walker metric.[...] Complementary kinematic and lensing mass profiles were derived from exhaustive analyses using the data from the Cluster Lensing And Supernova survey with Hubble (CLASH) and the spectroscopic follow-up with the Very Large Telescope (CLASH-VLT). Whereas the kinematic mass profile tracks only the time-time part of the perturbed metric (i.e. only $Φ$), the lensing mass profile reflects the contribution of both time-time and space-space components (i.e. the sum $Φ+Ψ$). We thus express $η$ as a function of the mass profiles and perform our analysis over the radial range $0.5\,Mpc\le r\le r_{200}=1.96\,Mpc$. Using a spherical Navarro-Frenk-White mass profile, which well fits the data, we obtain $η(r_{200})=1.01\,_{-0.28}^{+0.31}$ at the 68\% C.L. We discuss the effect of assuming different functional forms for mass profiles and of the orbit anisotropy in the kinematic reconstruction. Interpreting this result within the well-studied $f(R)$ modified gravity model, the constraint on $η$ translates into an upper bound to the interaction length (inverse of the scalaron mass) smaller than 2 Mpc. This tight constraint on the $f(R)$ interaction range is however substantially relaxed when systematic uncertainties in the analysis are considered. Our analysis highlights the potential of this method to detect deviations from general relativity, while calling for the need of further high-quality data on the total mass distribution of clusters and improved control on systematic effects.

description: This paper describes the preliminary tests developed in order to evaluate the outdoor performance of a High Concentrator Photovoltaic (HCPV) system located in the south Sardinia (Italy). Because of the plant location, the presented evaluation is useful in assessing the HCPV systems electrical productivity in the Mediterranean area, in different seasons of the year. The obtained results were referred to the weather conditions and the correlation between the energy production (EP) and the environmental parameters is presented. The results, in terms of electrical productivity obtained for the HCPV system, were compared with those of a traditional flat plate silicon photovoltaic plant, installed in the same location. The performances of both systems were analyzed for the same seasons and weather conditions. The obtained preliminary results provide a data base which is useful to compare the energy production of different photovoltaic technologies. Finally, the test results highlight the potentiality of HCPV technology in the Mediterranean area of Italy, confirming that CPV systems can be an important energy source in this region of Europe.

The asymptotic symmetries in Bondi gauge and at finite temperature span a supersymmetric extension of the warped Virasoro algebra at level zero. The boundary action is determined such that the bulk variational principle is ensured and turns out to be a super-warped Schwarzian theory at the vanishing level. We also study the thermodynamics of the black hole saddle in this model.

description: A layer of dielectric elastomer can be voltage actuated to behave as actuators, but needs to avoid the electromechanical instability of excessively thin down accompanied with electric breakdown. We develop a true method to analyze the electromechanical stability of dielectric elastomers by adopting the positive definiteness of the true tangential modulus matrix, and demonstrate that the previous method is only valid for the special case of zero prestress. Our new method is applicable for arbitrary prestress cases including zero prestress, with predictions consistent with available experimental measurements. Our theoretical results demonstrate the significant effects of prestress on critical voltage and critical actuation stretches.

description: Silicon-vacancy (SiV) centers in diamond are promising systems for quantum information applications due to their bright single photon emission and optically accessible spin states. Furthermore, SiV centers in low-strain diamond are insensitive to pertubations of the dielectric environment, i.e. they show very weak spectral diffusion. This property renders ensembles of SiV centers interesting for sensing applications. We here report on photoluminescence excitation (PLE) spectroscopy on an SiV ensemble in a low strain, CVD-grown high quality diamond layer, where we measure the fine structure with high resolution and obtain the linewidths and splittings of the SiV centers. We investigate the temperature dependence of the width and position of the fine structure peaks. Our measurements reveal linewidths of about 10 GHz as compared to a lifetime limited width on the order of 0.1 GHz. This difference arises from the inhomogeneous broadening of the transitions caused by residual strain. To overcome inhomogeneous broadening we use spectral hole burning spectroscopy which enables us to measure a nearly lifetime limited homogeneous linewidth of 279 MHz. Furthermore, we demonstrate evidence of coherent interaction in the system by driving a $Λ$-scheme. Additional measurements on single emitters created by ion implantation confirm the homogeneous linewidths seen in the spectral hole burning experiments and relate the ground state splitting to the decoherence rate.

description: The FP7 funded white’R project aims to develop a new manufacturing concept for the flexible tabbing and stringing of solar cells of varying shapes and sizes. white’R is a self-contained white room consisting of a multi-robotic island made up of intelligent, cooperative, fully automated “Plug&Produce (P&P)” modules. These modules interact with each other to accomplish multi-level optimization strategies related to both assembly and disassembly processes. The island will have the capability of scanning incoming solar cells to be (dis)assembled and associate them to a number of tasks to be executed. It will also have the intelligence to automatically recognise, select and configure the proper P&P equipment to be used for the operations. To date, a reference model has been created, detailing current production processes, considered products and foreseen equipment, in order to support the configurable implementation of the island. Preliminary designs for both the fixturing system and end effectors have been produced.

description: According to a general probabilistic principle, the natural divisors of friable integers (i.e.~free of large prime factors) should normally present a Gaussian distribution. We show that this indeed is the case with conditional density tending to 1 as soon as the standard necessary conditions are met. Furthermore, we provide explicit, essentially optimal estimates for the decay of the involved error terms. The size of the exceptional set is sufficiently small to enable recovery of the average behaviour in the same optimal range. Our argument combines the saddle-point method with new large deviations estimates for the distribution of certain additive functions.

description: Predictions of thunderstorm-related hazards are needed in several sectors, including first responders, infrastructure management and aviation. To address this need, we present a deep learning model that can be adapted to different hazard types. The model can utilize multiple data sources; we use data from weather radar, lightning detection, satellite visible/infrared imagery, numerical weather prediction and digital elevation models. We demonstrate the ability of the model to predict lightning, hail and heavy precipitation probabilistically on a 1 km resolution grid, with a temporal resolution of 5 min and lead times up to 60 min. Shapley values quantify the importance of the different data sources, showing that the weather radar products are the most important predictors for all three hazard types.

description: Extracellular vesicles (EVs) released from activated platelets contain microRNAs, the most abundant of which is hsa-miR-223-3p. Endogenous hsa-miR-223-3p suppresses the expression of tissue factor (TF), the initiator of the extrinsic coagulation pathway, in endothelial cells. Monocytes can be induced to express TF to enhance coagulation, but the role of hsa-miR-223-3p in regulating monocyte TF remains unknown. This study examined whether hsa-miR-223-3p from platelet-derived EVs (pdEVs) affects TF expression in monocytes. THP-1 cells, differentiated into a monocyte-like phenotype with 1α,25-dihydroxyvitaminD3, were transfected with hsa-miR-223-3p mimic or control microRNA. Alternatively, THP-1 cells were incubated with pdEVs from PAR1-agonist peptide activated-platelets, as platelet releasate, or pdEVs isolated by ultracentrifugation. Transfection with hsa-miR-223-3p mimic resulted in significant reductions in TF protein, determined by western blotting and flow cytometry and reduced procoagulant activity, measured by a TF-specific factor Xa generation assay, compared to cells transfected with control microRNA. This reduction was reversed by co-transfection with hsa-miR-223-3p inhibitor, AntagomiR-223. Incubation of THP-1 cells with pdEVs also decreased TF expression; however, this was not reversed by AntagomiR-223. Taken together, monocyte TF expression is downregulated by hsa-miR-223-3p, but when transferred via pdEVs the effect was not reversed with Antagomir-223, suggesting other pdEV components may contribute to TF regulation.

description: Relying on generalized-gradient and hybrid first-principles simulations, this work provides a complete characterization of the electronic properties of ZnO ultra-thin films, cut along the Body-Centered-Tetragonal(010), Cubane(100), h-BN(0001), Zinc-Blende(110), Wurtzite(10$\bar{1}$0) and (0001) orientations. The characteristics of the local densities of states are analyzed in terms of the reduction of the Madelung potential on under-coordinated atoms and surface states/resonances appearing at the top of the VB and bottom of the CB. The gap width in the films is found to be larger than in the corresponding bulks, which is assigned to quantum confinement effects. The components of the high frequency dielectric constant are determined and the absorption spectra of the films are computed. They display specific features just above the absorption threshold due to transitions from or to the surface resonances. This study provides a first understanding of finite size effects on the electronic properties of ZnO thin films and a benchmark which is expected to foster experimental characterization of ultra-thin films via spectroscopic techniques.

description: The only one example has been known of magnetic geodesic flow on the 2-torus which has a polynomial in momenta integral independent of the Hamiltonian. In this example the integral is linear in momenta and corresponds to a one parametric group preserving the Lagrangian function of the magnetic flow. In this paper the problem of integrability on one energy level is considered. This problem can be reduced to a remarkable Semi-hamiltonian system of quasi-linear PDEs and to the question of existence of smooth periodic solutions for this system. Our main result states that the pair of Liouville metric with zero magnetic field on the 2-torus can be analytically deformed to a Riemannian metric with small magnetic field so that the magnetic geodesic flow on an energy level is integrable by means of a quadratic in momenta integral. Thus our construction gives a new example of smooth periodic solution to the Semi-hamiltonian (Rich) quasi-linear system of PDEs.

description: Prostacyclin (PGI2) analogues (epoprostenol, treprostonil, iloprost) are the cornerstone of pulmonary arterial hypertension (PAH) treatment. PGI2 analogues inhibit platelet reactivity, but their impact on coagulation and fibrinolysis parameters has not been elucidated. We compared platelet reactivity, thrombin generation, clot permeation, and lysis properties in patients with PAH treated with PGI2 analogues (n = 20) and those not receiving PGI2 analogues (n = 20). Platelet reactivity was lower in patients treated with PGI2 analogues, compared to the control group, as evaluated with arachidonic acid (ASPI), adenosine diphosphate (ADP), and thrombin receptor-activating peptide-6 (TRAP) tests (p = .009, p = .02, p = .007, respectively). In the subgroup analysis, both treprostinil and epoprostenol decreased platelet reactivity to the similar extent. There were no differences regarding thrombin generation, clot permeation, and lysis parameters in patients receiving and not receiving PGI2 analogues (p ≥ .60 for all). In the subgroup analysis, there were no differences regarding coagulation and fibrinolysis parameters between treprostinil, epoprostenol, and no PGI2 analogues. To conclude, patients with PAH treated with PGI2 analogues have reduced platelet reactivity, but similar clot formation and lysis parameters, compared to patients not receiving PGI2 analogues. Further randomized clinical trials are required to confirm these findings.

description: Abstract- The banking business is one of the most innovative fields of technology. All sectors, including banking, have been affected by digital technical advancements. In fact, it has led to significant improvements in runway width, but also significant endurance improvements, but also cost reduction. In an increasingly competitive environment, banks are working to build technology that would enable customers to receive banking services as easily as possible by widening the number of digital banking services available. As a consequence of the widespread usage of online banking facilities, our country's financial sector has made significant strides in recent years. The aim of this study is to look into the factors that influence internet banking usage as well as the factors for its acceptance. According to the report, the most significant factors affecting internet banking use and adoption are usability, suitability, and longevity. Internet banking is preferred by consumers because it saves time, is accessible 24 hours a day, and is simple and fast. Many people refuse to use online banking because they feel it is unsafe and that on-site banking is more comfortable.

description: We experimentally re-evaluate the fine structure of Sn$^{11+...14+}$ ions. These ions are essential in bright extreme-ultraviolet (EUV) plasma-light sources for next-generation nanolithography, but their complex electronic structure is an open challenge for both theory and experiment. We combine optical spectroscopy of magnetic dipole $M1$ transitions, in a wavelength range covering 260\,nm to 780\,nm, with charge-state selective ionization in an electron beam ion trap. Our measurements confirm the predictive power of \emph{ab initio} calculations based on Fock space coupled cluster theory. We validate our line identification using semi-empirical Cowan calculations with adjustable wavefunction parameters. Available Ritz combinations further strengthen our analysis. Comparison with previous work suggests that line identifications in the EUV need to be revisited.

description: Spin torque oscillators (STOs) are emerging microwave devices that can potentially be used in spin-logic devices and the next-generation high-speed computing architecture. Thanks to their non-linear nature, STOs are easily tunable by the magnetic field and the dc current. Spin Hall nano-oscillators (SHNOs) are promising types of STOs and most of the current studies focus on localized modes that can be easily excited. Here, we study using micromagnetic simulations, the nature of the spin-torque-induced excitations in nanowire devices made of perpendicular magnetic anisotropy (PMA) material. Our results showed that upon including PMA the excitation of localized and propagating spin wave modes is feasible. We study the nature of the mode excitations as a function of the PMA strength (\text{K}$_u$), and the current. Indeed, we estimate a critical value of \text{K}$_u$ to allow for the excitation of the propagating spin wave. We attribute this mode selectivity between localized and propagating modes to a switch in the sign of the nonlinearity of the system from negative to positive at a non-zero \text{K}$_u$ which is supported by analytical calculations. Our results provide deep insight into engineering reconfigurable microwave devices for future magnonic and computational applications.

description: Wind loads must be taken into account for the design of any outdoor structure. For solar trackers, the analysis of the wind loads presents a number of challenges as the existing, officially released tracker standards do not provide sufficient guidelines regarding how wind loads should be calculated and which assumptions should be applied. Building standards such as the Eurocode or US Building Code do not relate specifically to solar trackers and could result in overdesign. The IEC 62817 (Design Qualification For Solar Trackers) is in the final draft stage and addresses the issue of determining the winds loads on solar trackers. Three methods are described: wind tunnel analysis, CFD analysis, and an equation based calculation. This paper provides a comparison of the wind load results obtained using the IEC 62817 draft, wind tunnel tests and CFD analyses.

description: The quasinormal modes of relativistic compact objects encode important information about the gravitational response associated with astrophysical phenomena. Detecting such oscillations would provide us with a unique understanding of the properties of compact stars, and may give definitive evidence for the existence of black holes. However, computing quasinormal modes in realistic astrophysical environments is challenging due to the complexity of the spacetime background and of the dynamics of the perturbations. We discuss two complementary methods for computing the quasinormal modes of spherically symmetric astrophysical systems, namely, the direct integration method and the continued-fraction method. We extend these techniques to dealing with generic coupled systems of linear equations, with the only assumption being the interaction between different fields is effectively localized within a finite region. In particular, we adapt the continued-fraction method to include cases where a series solution can be obtained only outside an effective region. As an application, we compute the polar quasinormal modes of boson stars by using the continued-fraction method for the first time. The methods discussed here can be applied to other situations in which the perturbations effectively couple only within a finite region of space.

description: Concentrator Solar Cell, CPV, is one of the most efficient kind of solar cell. In order to acquire high efficiency, CPV should be arranged to be perpendicular to the incident sunlight and properly cooled. Previously, it was done by applying sensor-based solar tracking and adapting cooling systems to recycle the heat generated in CPV. However, the usability of sensor decreases when it is not sunny and the efficiency of current cooling system is not enough. In this research, we propose a CPV system which includes a program-based tracking and a cooling module that contains Heatpipes. As a result, we could verify that the designed hybrid solar tracking system had high accuracy by comparing the official data provided by the Korea Astronomy and Space Science Institute. We could also confirmed that introduction of Heatpipes improved the total efficiency of CPV by 3% for basic module by conducting simulations and experiments on the designed system. Moreover, we could achieve higher efficiency with optimization of arrangements of Heatpipes. After that, we built a system combined of 16ea single modules to check the feasibility of the system as a heating device. We conducted experiments on the system and could verify that the electricity and heat produced were 390.32W, which showed the practicality of the system.
