description: Short-term load forecasting (STLF) is vital for the effective and economic operation of power grids and energy markets. However, the non-linearity and non-stationarity of electricity demand as well as its dependency on various external factors renders STLF a challenging task. To that end, several deep learning models have been proposed in the literature for STLF, reporting promising results. In order to evaluate the accuracy of said models in day-ahead forecasting settings, in this paper we focus on the national net aggregated STLF of Portugal and conduct a comparative study considering a set of indicative, well-established deep autoregressive models, namely multi-layer perceptrons (MLP), long short-term memory networks (LSTM), neural basis expansion coefficient analysis (N-BEATS), temporal convolutional networks (TCN), and temporal fusion transformers (TFT). Moreover, we identify factors that significantly affect the demand and investigate their impact on the accuracy of each model. Our results suggest that N-BEATS consistently outperforms the rest of the examined models. MLP follows, providing further evidence towards the use of feed-forward networks over relatively more sophisticated architectures. Finally, certain calendar and weather features like the hour of the day and the temperature are identified as key accuracy drivers, providing insights regarding the forecasting approach that should be used per case.

description: Despite the fundamental importance of quantum entanglement in many-body systems, our understanding is mostly limited to bipartite situations. Indeed, even defining appropriate notions of multipartite entanglement is a significant challenge for general quantum systems. In this work, we initiate the study of multipartite entanglement in a rich, yet tractable class of quantum states called stabilizer tensor networks. We demonstrate that, for generic stabilizer tensor networks, the geometry of the tensor network informs the multipartite entanglement structure of the state. In particular, we show that the average number of Greenberger-Horne-Zeilinger (GHZ) triples that can be extracted from a stabilizer tensor network is small, implying that tripartite entanglement is scarce. This, in turn, restricts the higher-partite entanglement structure of the states. Recent research in quantum gravity found that stabilizer tensor networks reproduce important structural features of the AdS/CFT correspondence, including the Ryu-Takayanagi formula for the entanglement entropy and certain quantum error correction properties. Our results imply a new operational interpretation of the monogamy of the Ryu-Takayanagi mutual information and an entropic diagnostic for higher-partite entanglement. Our technical contributions include a spin model for evaluating the average GHZ content of stabilizer tensor networks, as well as a novel formula for the third moment of random stabilizer states, which we expect to find further applications in quantum information.

description: Epidemics, neural cascades, power failures, and many other phenomena can be described by a diffusion process on a network. To identify the causal origins of a spread, it is often necessary to identify the triggering initial node. Here we define a new morphological operator and use it to detect the origin of a diffusive front, given the final state of a complex network. Our method performs better than randomized trials as well as centrality based methods. More importantly, our method is applicable regardless of the specifics of the forward model, and therefore can be applied to a wide range of systems such as identifying the patient zero in an epidemic, pinpointing the neuron that triggers a cascade, identifying the original malfunction that causes a catastrophic infrastructure failure, and inferring the ancestral species from which a heterogeneous population evolves.

description: Algorithmic differentiable ray tracing is a new paradigm that allows one to solve the forward problem of how light propagates through an optical system while obtaining gradients of the simulation results with respect to parameters specifying the optical system. Specifically, the use of algorithmically differentiable non-sequential ray tracing provides an opportunity in the field of illumination design. We demonstrate its potential by designing freeform lenses that project a prescribed irradiance distribution onto a plane. The challenge consists in finding a suitable surface geometry of the lens so that the light emitted by a light source is redistributed into a desired irradiance distribution. We discuss the crucial steps allowing the non-sequential ray tracer to be differentiable. The obtained gradients are used to optimize the geometry of the freeform, and we investigate the effectiveness of adding a multi-layer perceptron neural network to the optimization that outputs parameters defining the freeform lens. Lenses are designed for various sources such as collimated ray bundles or point sources, and finally, a grid of point sources approximating an extended source. The obtained lens designs are finally validated using the commercial non-sequential ray tracer LightTools.

Anomic Dependence and Corruptive Contagion. Regulatory Hypercomplexity and Social Fragmentation in the Mid-Global Era

Year: 2022

description: Corruption is normally perceived as a system of power that overlaps the state-system. The average citizen seems subjugated to its workings and refrains from fighting against it. The reasons of such an attitude could be subjected to different explanations; there is no doubt that, generally, the social actors consider the state apparatus and its institutions responsible for their lack of action in the face of a widespread practice of corruption, within society. Another relevant aspect is that, due to the transversal nature of corruption, all its proceedings seem to swallow the root of the practice, namely the first corrupted act. As consequence of that, corruption, as a phenomenon, seems to operate as a spiderweb, from which it becomes difficult to untangle.

description: Motivated by the need for low electron dose transmission electron microscopy imaging, we report the optimal frame dose (i.e. $e^-/A^{2}$) range for object detection and segmentation tasks with neural networks. The MSD-net architecture shows promising abilities over the industry standard U-net architecture in generalising to frame doses below the range included in the training set, for both simulated and experimental images. It also presents a heightened ability to learn from lower dose images. The MSD-net displays mild visibility of a Au nanoparticle at 20-30 $e^-/A^{2}$, and converges at 200 $e^-/A^{2}$ where a full segmentation of the nanoparticle is achieved. Between 30 and 200 $e^-/A^{2}$ object detection applications are still possible. This work also highlights the importance of modelling the modulation transfer function when training with simulated images for applications on images acquired with scintillator based detectors such as the Gatan Oneview camera. A parametric form of the modulation transfer function is applied with varying ranges of parameters, and the effects on low electron dose segmentation is presented.

description: We explore the connection between the process of relaxation in the BMN matrix model and the physics of black holes in AdS/CFT. Focusing on Dyson-fluid solutions of the matrix model, we perform numerical simulations of the real time dynamics of the system. By quenching the equilibrium distribution we study the quasi-normal oscillations of scalar single trace observables, we isolate the lowest quasi-normal mode, and we determine its frequencies as function of the energy. Considering the BMN matrix model as a truncation of $\mathcal{N}=4$ SYM, we also compute the frequencies of the quasi-normal modes of the dual scalar fields in the AdS$_5$-Schwarzschild background. We compare the results, and we find a surprising similarity.

description: Joint travel decisions, particularly related to social activities remain poorly explained in traditional behavioral models. A key reason for this is the lack of empirical data, and the difficulties associated with collecting such data in the first place. To address this problem, we propose Text-aided Group Decision-making Process Observation Method (x-GDP), a novel survey methodology to collect data on joint leisure activities, from all members of a given clique. Through this method we are able to observe not only the outcome (i.e., the joint activity location chosen) but also the decision-making process itself, including the alternatives that compose the choice set, individual and clique characteristics that might affect the choice process, as well as the discussion behind the choice via texts. Observing such a process will allow researchers to gain a deeper understanding of the joint decision-making process, including how alternatives are weighted, how members interact with each other, and finally how joint choices are made. In this paper we introduce the results of a x-GDP survey implementation focusing on joint eating-out activities in the Greater Tokyo Area, giving a detailed overview of the survey components, execution logistics and initial insights on the data. This is to the best of our knowledge the first attempt to observe group joint travel decisions in real time through a zoom-moderated experiment.

Family Relationships at the Time of COVID-19: the Perspective of the Italian Sociological Review
Creators: name: Di Nicola, Paola
Publisher: name: Italian Sociological Review
Year: 2022

description: The pandemic highlighted social processes that were unknown to many citizens. Not only did it reveal the high level of interdependency between nations and continents but also the marked disparity between the beneficiaries and victims of globalization. Some countries were provided with tangible proof of their underlying fragility, especially in terms of their economies and access to resources (such as vaccines). The gulf between rich and poor nations was also underlined, as well as domestic poverty gaps. Inequality and injustice emerged with all their tragic overtones. It is necessary to come to terms with, rather than cancel, the past in order to imagine a different future, also as far as the family is concerned. The analysis of the research data shows that Italian households adopted coping strategies during the lockdown. Financially speaking, they drew on their savings and reduced certain forms of consumption, while couples – above all women – tackled the emergency by buckling down to care work and family responsibilities. The social and relational repercussions of all this have yet to be fully considered. In light of these remarks, envisioning the future of the current and new generations becomes a high-stakes game. Pursuing the dynamics triggered by the pandemic will herald a return to the traditional family model with the wife-mother as homemaker or homeworker and the husband-father employed in flexible work with little security (meaning also a family with fewer financia

description: Air pollution, as increasing concern of global extent, has been the focus of many worldwide research projects. Especially particulate matter pollution and disposure, since they can be linked reliably to adverse health effects such as respiratory and cardiovascular diseases. New technologies are offering low-cost sensors measuring the particulate matter concentrations in different conditions; however, the performance of those sensors in the field with regard to different factors such as relative humidity had to be examined. This research aimed for the development and construction of a low-cost measuring platform, using a low-cost particulate matter sensor, for mobile measurements of the temporal and spatial distribution of particulate matter in ambient air. The rack railway train (Zacke) in Stuttgart was used as medium of transportation. Additionally, continuous meteorological measurements and several particulate matter measurement campaigns were performed. It was observed, that the small particulate matter sizes (PM2.5 and PM1) dominated the concentrations throughout all measurements. Additionally, there was an overestimation of particulate matter concentration in contrast to the comparative devices, due to the hygroscopic growth of particles

description: In elite cycling, small aerodynamic gains achieved through modifications to the skinsuit on a cyclist's limbs can provide a significant competitive advantage, as winning margins may be only milli-seconds in a multi-minute race. Often, a cylinder model has been used to represent the flow past an athlete's limbs. This thesis pays attention to capturing the fundamental flow characteristics of an isolated cylinder through computer modelling, especially the details of airflow near the surface as the speed changes, with validation through experiments. That study fed into improving numerical simulations on the cyclist/bicycle combination to predict the aerodynamic drag attributed to separate body parts as the legs move through a pedalling cycle. Finally, modelling of the effect of surface treatments to the limbs provides key insights on changes to the drag contributions of sub-body parts.

description: La valutazione premiale della ricerca rappresenta un circuito di potere installato direttamente nel sistema operativo del sapere. Declino della libertà accademica, burocratizzazione e proprietarizzazione della scienza, e demotivazione dei ricercatori sono alcuni dei suoi più gravi effetti indesiderati o forse, al contrario, deliberatamente perseguiti.

description: Fibre reinforced polymer (FRP) composites have received worldwide interests to use as load-bearing components in structural applications. The utilization of FRP composites into structural applications requires comprehensive knowledge of their mechanical performance. In this study, the mechanical performance of FRP columns and sandwich assemblies are thoroughly investigated under different compressive loading scenarios through experimental, analytical and numerical approaches. The results from above studies may broaden the understanding of the mechanical performance of FRP columns and sandwich assemblies and may benefit future structural implementations of FRP composites members into the modular assembly of prefabricated buildings especially for column and wall applications.

description: Phase coupling between auto-oscillators is central for achieving coherent responses such as synchronization. Here we present an experimental approach to probe it in the case of two dipolarly coupled spin-torque vortex nano-oscillators using an external microwave field. By phase-locking one oscillator to the microwave field, we observe frequency pulling on the second oscillator. From coupled Thiele equations we show analytically that this frequency pulling results from concerted actions of dipolar and microwave couplings. The analysis allows us to determine the amplitude of dipolar coupling and the phase lag of each oscillator, yielding important information for the implementation of large oscillator networks.

description: The aim of this research is to understand the effects of EMI on basic analog building blocks such as current mirrors, OpAmps, and bandgap references, and subsequently develop practical EMI immune solutions. This research also looks into effects of EMI on wireline receivers due to the conducted disturbances through the channel. It also develops a methodology to help emulate an electromagnetic environment for the purpose of circuit simulations. Thus in conclusion, this research has designed, fabricated, and demonstrated the effectiveness of the proposed EMI immune solutions, and also developed analytical models to better understand the effect of various circuit parameters on the EMI performance of a circuit.

description: En el diseño, formulación y desarrollo de nuevos productos alimenticios o el mejoramiento de los productos tradicionales, están condicionados al conocimiento de las características fisicoquímicas, bromatológicas y reológicas de sus componentes. Un eje de valiosa importancia en el área de los alimentos son las dispersiones complejas tales como las emulsiones. Ahora bien, en la formulación y elaboración de las emulsiones se utilizan agentes surfactantes como las proteínas, que se constituyen en barreras moleculares que estabilizan las dispersiones y favorecen su formación. De acuerdo a lo anterior se estandarizara una emulsión alimentaria tipo aceite en agua (O/W) con proteína de Arenca (Triportheus magdalenae), para esto se ha realizado la caracterización fisicoquímica y bromatológica del musculo del pescado, obteniendo un porcentaje de proteína, de 17,85±0,12 permitiendo la recuperación de 72 a 90% en el aislado proteico, para su aplicación en productos alimenticios como pueden ser salsa para ensaladas, mayonesas, pastas para untar, aderezos entre otros productos. Por lo anterior se ha obtenido una emulsión alimentaria tipo aceite en agua (O/W) estabilizada con proteínas aisladas de la Arenca (Triportheus magdalenae), con un comportamiento de fluido No Newtoniano tipo pseudoplástico, el cual presenta una distribución de pequeñas gotas de forma homogénea. Los análisis para evaluar la estabilización se realizaron después de 24 horas de elaborada la emulsión mostrando estabilidad en el producto.
On the magnetotransport of Weyl semimetals due to the chiral anomaly

Subjects: subject: Mesoscale and Nanoscale Physics (cond-mat.mes-hall)

description: We study electric field and temperature gradient driven magnetoconductivity of a Weyl semimetal system. To analyze the responses, we utilize the kinetic equation with semiclassical equations of motion modified by the Berry curvature and orbital magnetization of the wave-packet. Apart from known positive quadratic magnetoconductivity, we show that due to chiral anomaly, the magnetconductivity can become non-analytic function of the magnetic field, proportional to 3/2 power of the magnetic field at finite temperatures. We also show that time-reversal symmetry breaking tilt of the Dirac cones results in linear magnetoconductivity. This is due to one-dimensional chiral anomaly the tilt is responsible for.

description: An iron and steel industry generates around 150 to 200 kg of steel slag per tonne of steel generated in basic oxygen furnace mostly using Linz-Donawitz (LD) process. In countries like India and China, re-utilization of steel slag/LD slag for construction works and production of cement is limited by virtue of its chemical characteristics such as presence of free lime, free magnesium and phosphorous. Open dumping or storing of the LD slag is not an environmentally sound or economically viable solution. The aim of this study is to find an environmentally sustainable and techno-economically feasible technology for re-utilization of LD slag. Synthesizing soil using LD slag is one such option which then could be used for several applications such as reclamation of mines, landfills, landscaping, vegetation on highway medians and public gardens.
