description: Let $G$ be a countably infinite group, and let $μ$ be a generating probability measure on $G$. We study the space of $μ$-stationary Borel probability measures on a topological $G$ space, and in particular on $Z^G$, where $Z$ is any perfect Polish space. We also study the space of $μ$-stationary, measurable $G$-actions on a standard, nonatomic probability space. Equip the space of stationary measures with the weak* topology. When $μ$ has finite entropy, we show that a generic measure is an essentially free extension of the Poisson boundary of $(G,μ)$. When $Z$ is compact, this implies that the simplex of $μ$-stationary measures on $Z^G$ is a Poulsen simplex. We show that this is also the case for the simplex of stationary measures on $\{0,1\}^G$. We furthermore show that if the action of $G$ on its Poisson boundary is essentially free then a generic measure is isomorphic to the Poisson boundary. Next, we consider the space of stationary actions, equipped with a standard topology known as the weak topology. Here we show that when $G$ has property (T), the ergodic actions are meager. We also construct a group $G$ without property (T) such that the ergodic actions are not dense, for some $μ$. Finally, for a weaker topology on the set of actions, which we call the very weak topology, we show that a dynamical property (e.g., ergodicity) is topologically generic if and only if it is generic in the space of measures. There we also show a Glasner-King type 0-1 law stating that every dynamical property is either meager or residual.

Systems engineering approaches to safety in transport systems

description: During driving, driver behavior monitoring may provide useful information to prevent road traffic accidents caused by driver distraction. It has been shown that 90% of road traffic accidents are due to human error and in 75% of these cases human error is the only cause. Car manufacturers have been interested in driver monitoring research for several years, aiming to enhance the general knowledge of driver behavior and to evaluate the functional state as it may drastically influence driving safety by distraction, fatigue, mental workload and attention. Fatigue and sleepiness at the wheel are well known risk factors for traffic accidents. The Human Factor (HF) plays a fundamental role in modern transport systems. Drivers and transport operators control a vehicle towards its destination in according to their own sense, physical condition, experience and ability, and safety strongly relies on the HF which has to take the right decisions. On the other hand, we are experiencing a gradual shift towards increasingly autonomous vehicles where HF still constitutes an important component, but may in fact become the "weakest link of the chain", requiring strong and effective training feedback. The studies that investigate the possibility to use biometrical or biophysical signals as data sources to evaluate the interaction between human brain activity and an electronic machine relate to the Human Machine Interface (HMI) framework. The HMI can acquire human signals to analyse the specific embedded structures and recognize the behavior of the subject during his/her interaction with the machine or with virtual interfaces as PCs or other communication systems. Based on my previous experience related to planning and monitoring of hazardous material transport, this work aims to create control models focused on driver behavior and changes of his/her physiological parameters. Three case studies have been considered using the interaction between an EEG system and external device, such as driving simulators or electronical components. A case study relates to the detection of the driver's behavior during a test driver. Another case study relates to the detection of driver's arm movements according to the data from the EEG during a driver test. The third case is the setting up of a Brain Computer Interface (BCI) model able to detect head movements in human participants by EEG signal and to control an electronic component according to the electrical brain activity due to head turning movements.

description: We give some properties of the subgroup $G_n(\mathbb{C})$ of the group of birational self-maps of $\mathbb{P}^n_\mathbb{C}$ generated by the standard involution and the group of automorphisms of $\mathbb{P}^n_\mathbb{C}$. We prove that there is no nontrivial finite-dimensional linear representation of $G_n(\mathbb{C})$. We also establish that $G_n(\mathbb{C})$ is perfect, and that $G_n(\mathbb{C})$ equipped with the Zariski topology is simple. Furthermore if $φ$ is an automorphism of $\mathrm{Bir}(\mathbb{P}^n_\mathbb{C})$, then up to birational conjugacy, and up to the action of a field automorphism $φ_{\vert G_n(\mathbb{C})}$ is trivial.

description: By considering type B analogs of permutations and tableaux, we extend abstract dual equivalence to type B in two directions. In one direction, we define involutions on signed permutations and shifted tableaux that give a weak dual equivalence, thereby giving another proof of the Schur positivity of Schur Q- and P-functions. In another direction, we define an abstract shifted dual equivalence parallel to dual equivalence and prove that it can be used to establish Schur P-positivity of a function expressed as a sum of shifted fundamental quasisymmetric functions.

On the equivariant Tamagawa number conjecture in tame CM-extensions, II
Creators: name: Nickel, Andreas
Publisher: name: Universität Regensburg
Year: 2010
Subjects: subject: 500 Naturwissenschaften

description: We use the notion of non-commutative Fitting invariants to give a reformulation of the equivariant Iwasawa main conjecture (EIMC) attached to an extension F=K of totally real fields with Galois group G, where K is a global number field and G is a p-adic Lie group of dimension 1 for an odd prime p. We attach to each finite Galois CM-extension L=K with Galois group G a module SKu(L=K) over the center of the group ring ZG which coincides with the Sinnott-Kurihara ideal if G is abelian. We state a conjecture on the integrality of SKu(L=K) which follows from the equivariant Tamagawa number conjecture (ETNC) in many cases, and is a theorem for abelian G. Assuming the validity of the EIMC and the vanishing of the Iwasawa μ-invariant, we compute Fitting invariants of certain Iwasawa modules, and we show that this implies the minus part of the ETNC at p for an infinite class of (non-abelian) Galois CM-extensions of number fields which are at most tamely ramified above p, provided that (an appropriate p-part of) the integrality conjecture holds.
Environmental Policy and Investment Location: The Risk of Carbon Leakage in the EU ETS

subject: EU ETS

description: This paper empirically investigates the effect of the European Emission Trading Scheme (EU ETS) on cross-country investments. To avoid carbon leakage, the scheme allocates a number of free allowances to firms at risk of relocating investments in areas outside the EU ETS. To study this problem, we employ a model of the firm’s investment decision in conjunction with novel firm-level data. In contrast with most previous literature, we stress the importance of firms’ heterogeneity in the analysis and leverage it. We derive conditions for the firm’s optimal emissions to construct a measure of investment sensitivity to carbon pricing from observed pollution data. This allows to identify the effect of the EU ETS on international investments by comparing the expected profits from investing in several different countries. We find that investments react to carbon pricing and that the effect is stronger for more polluting investments. However, the aggregate amount of diverted investments is small. We moreover show that the lost investments do not justify, alone, the generous compensations scheme aimed at retaining investments.
Evidence synthesis for count distributions based on heterogeneous and incomplete aggregated data

description: The analysis of count data is commonly done using Poisson models. Negative binomial models are a straightforward and readily motivated generalization for the case of overdispersed data, i.e., when the observed variance is greater than expected under a Poissonian model. Rate and overdispersion parameters then need to be considered jointly, which in general is not trivial. Here we are concerned with evidence synthesis in the case where the reporting of data is rather heterogeneous, i.e., events are reported either in terms of mean event counts, the proportion of event-free patients, or rate estimates and standard errors. Either figure carries some information about the relevant parameters, and it is the joint modeling that allows for coherent inference on the parameters of interest. The methods are motivated and illustrated by a systematic review in chronic obstructive pulmonary disease.

description: Although the Lasso has been extensively studied, the relationship between its prediction performance and the correlations of the covariates is not fully understood. In this paper, we give new insights into this relationship in the context of multiple linear regression. We show, in particular, that the incorporation of a simple correlation measure into the tuning parameter can lead to a nearly optimal prediction performance of the Lasso even for highly correlated covariates. However, we also reveal that for moderately correlated covariates, the prediction performance of the Lasso can be mediocre irrespective of the choice of the tuning parameter. We finally show that our results also lead to near-optimal rates for the least-squares estimator with total variation penalty.
Exact and Heuristic Algorithms for Energy-Efficient Scheduling
Creators: name: RONCO, ROBERTO
Publisher: name: Universit� degli studi di Genova
Year: 2022

description: The combined increase of energy demand and environmental pollution at a global scale is entailing a rethinking of the production models in sustainable terms. As a consequence, energy suppliers are starting to adopt strategies that flatten demand peaks in power plants by means of pricing policies that stimulate a change in the consumption practices of customers. A representative example is the Time-of-Use (TOU)-based tariffs policy, which encourages electricity usage at off-peak hours by means of low prices, while penalizing peak hours with higher prices. To avoid a sharp increment of the energy supply costs, manufacturing industry must carefully reschedule the production process, by shifting it towards less expensive periods. The TOU-based tariffs policy induces an implicit partitioning of the time horizon of the production into a set of time slots, each associated with a non-negative cost that becomes a part of the optimization objective. This thesis focuses on a representative bi-objective energy-efficient job scheduling problem on parallel identical machines under TOU-based tariffs by delving into the description of its inherent properties, mathematical formulations, and solution approaches. Specifically, the thesis starts by reviewing the flourishing literature on the subject, and providing a useful framework for theoreticians and practitioners. Subsequently, it describes the considered problem and investigates its theoretical properties. In the same chapter, it presents a first mathematical model for the problem, as well as a possible reformulation that exploits the structure of the solution space so as to achieve a considerable increase in compactness. Afterwards, the thesis introduces a sophisticated heuristic scheme to tackle the inherent hardness of the problem, and an exact algorithm that exploits the mathematical models. Then, it shows the computational efficiency of the presented solution approaches on a wide test benchmark. Finally, it presents a perspective on future research directions for the class of energy-efficient scheduling problems under TOU-based tariffs as a whole.
Active-set prediction for interior point methods using controlled perturbations

Publisher: name: arXiv
Year: 2014
Subjects: subject: Optimization and Control (math.OC)
subject: FOS: Mathematics

description: We propose the use of controlled perturbations to address the challenging question of optimal active-set prediction for interior point methods. Namely, in the context of linear programming, we consider perturbing the inequality constraints/bounds so as to enlarge the feasible set. We show that if the perturbations are chosen appropriately, the solution of the original problem lies on or close to the central path of the perturbed problem. We also find that a primal-dual path-following algorithm applied to the perturbed problem is able to accurately predict the optimal active set of the original problem when the duality gap for the perturbed problem is not too small; furthermore, depending on problem conditioning, this prediction can happen sooner than predicting the active set for the perturbed problem or when the original one is solved. Encouraging preliminary numerical experience is reported when comparing activity prediction for the perturbed and unperturbed problem formulations.

Human-Machine Interfaces using Distributed Sensing and Stimulation Systems
Creators: name: ABBASS, YAHYA
Publisher: name: Universit� degli studi di Genova
Year: 2022

description: As the technology moves towards more natural human-machine interfaces (e.g. bionic limbs, teleoperation, virtual reality), it is necessary to develop a sensory feedback system in order to foster embodiment and achieve better immersion in the control system. Contemporary feedback interfaces presented in research use few sensors and stimulation units to feedback at most two discrete feedback variables (e.g. grasping force and aperture), whereas the human sense of touch relies on a distributed network of mechanoreceptors providing a wide bandwidth of information. To provide this type of feedback, it is necessary to develop a distributed sensing system that could extract a wide range of information during the interaction between the robot and the environment. In addition, a distributed feedback interface is needed to deliver such information to the user. This thesis proposes the development of a distributed sensing system (e-skin) to acquire tactile sensation, a first integration of distributed sensing system on a robotic hand, the development of a sensory feedback system that compromises the distributed sensing system and a distributed stimulation system, and finally the implementation of deep learning methods for the classification of tactile data. It?s core focus addresses the development and testing of a sensory feedback system, based on the latest distributed sensing and stimulation techniques. To this end, the thesis is comprised of two introductory chapters that describe the state of art in the field, the objectives, and the used methodology and contributions; as well as six studies that tackled the development of human-machine interfaces.
Black hole spin - orbit misalignment in black hole in the X-ray binary MAXI J1820+070
Creators: name: Poutanen, Juri
Publisher: name: Zenodo
Year: 2022
Subjects: accretion, accretion discs — black holes — polarization — X-ray binaries

description: The observational signatures of black holes in X-ray binary systems depend on their masses, spins,
 accretion rate, and the misalignment angle between the black hole spin and the orbital angular
 momentum. We present optical polarimetric observations of the black hole X-ray binary MAXI
 J1820+070 with high-precision polarimeter DIPol-UF at the Nordic Optical Telescope, from which we
 constrain the position angle of the binary orbital axis. Combining this with previous determinations
 of the relativistic jet orientation, which traces the black hole spin, and the inclination of the orbit, we
 determine a lower limit of 40 deg on the black hole spin-orbital angular momentum misalignment
 angle. The misalignment must originate from either the binary evolution or black hole formation
 stages. If other X-ray binaries have similarly large misalignments, these would bias measurements
 of black hole masses and spins from X-ray observations. A high misalignment adds complexity
 to the models of the X-ray and optical quasi-periodic oscillations observed from black hole X-ray
 binaries in their hard state. We will also discuss the prospect of measuring misalignment using the
 polarimetric data from the Imaging X-ray Polarimetry Explorer.

Let $\mathcal{A}$ be an abelian category and let $(\mathcal{U}, \mathcal{V})$ be a $t$-structure on the bounded derived category $D^b \mathcal{A}$ with heart $\mathcal{H}$. We investigate when the natural embedding $\mathcal{H} \to D^b \mathcal{A}$ can be extended to a triangle equivalence $D^b \mathcal{H} \to D^b \mathcal{A}$. Our focus of study is the case where $\mathcal{A}$ is the category of finite-dimensional modules over a finite-dimensional hereditary algebra. In this case, we prove that such an extension exists if and only if the $t$-structure is bounded and the aisle $\mathcal{U}$ of the $t$-structure is closed under the Serre functor.

Resonant mechanisms that produce near-Sun asteroids

Year: 2023
Subjects: subject: Earth and Planetary Astrophysics (astro-ph.EP)

description: All near-Earth asteroids (NEAs) that reach sufficiently small perihelion distances will undergo a so-called super-catastrophic disruption. The mechanisms causing such disruptions are currently unknown or, at least, undetermined. To help guide theoretical and experimental work to understand the disruption mechanism, we use numerical simulations of a synthetic NEA population to identify the resonant mechanisms that are responsible for driving NEAs close to the Sun, determine how these different mechanisms relate to their dynamical lifetimes at small heliocentric distances and calculate the average time they spend at different heliocentric distances. Typically, resonances between NEAs and the terrestrial and giant planets are able to dramatically reduce the perihelion distances of the former. We developed an algorithm that scans the orbital evolution of asteroids and automatically identifies occurrences of mean motion and secular resonances. We find that most near-Sun asteroids are pushed to small perihelion distances by the 3:1J and 4:1J mean-motion resonances with Jupiter, as well as the secular resonances v6, v5,v3 and v4. The time-scale of the small-perihelion evolution is fastest for the 4:1J, followed by the 3:1J, while v5 is the slowest.~7% of the test asteroids were not trapped in a resonance during the latest stages of their dynamical evolution, which suggests that the secular oscillation of the eccentricity due to the Kozai mechanism, a planetary close encounter or a resonance that we have not identified pushed them below the estimated average disruption distance.

subject: Automation and technology in building and construction

description: The quality of construction projects directly impacts public safety. Poor quality leads to defects, failures, and risks, necessitating frequent and accurate quality control, especially for structural members of buildings. This thesis aims to propose an end-to-end geometric quality inspection framework that encompasses structural member detection within point clouds, compliance checks based on relevant regulations, and digitalized documentation using digital twin platforms. The proposed framework aims to be generalizable to different types of structural members, including beams, columns, and bracings, across a wide range of construction projects that minimize the need for manual interventions.

description: El foie-gras de pato nació en el sudoeste de Francia en el transcurso del siglo XVIII gracias a la perfecta integración en esta parte del viejo mundo de dos aportaciones agronómicas de América: el pato real mexicano (Cairina moschata) y el maíz (Zea mays). La génesis de este foie-gras, lo más consumido en el mundo contemporáneo, permite pensar con sutilidad en los intercambios y los procesos de apropiación que siguieron la puesta en relación de los dos mundos a finales del siglo XV. Además, la historia reciente del foie-gras conduce a analizar tanto fenómenos de criollización agrícola y culinaria en varios países americanos y europeos como influencias ideológicas en las representaciones de este producto de los dos lados del Atlántico. En consecuencia, el caso del foie gras invita a reflexionar sobre la doble dimensión del mestizaje alimenticio que acompaña la globalización de los intercambios en nuestro planeta: biológica y cultural, productiva y simbólica.

L’origine du foie gras de canard, le plus consommé dans le monde contemporain, permet de réfléchir aux subtilités des échanges et des processus d’appropriation qui suivirent la mise en relation des deux mondes à la fin du XVe siècle. En outre, l’histoire récente du foie gras conduit à analyser des phénomènes de créolisation agricole et culinaire en divers pays américains et européens, mais aussi des influences idéologiques dans les représentations de ce produit des deux côtés de l’Atlantique.

Embedded Machine Learning: Emphasis on Hardware Accelerators and Approximate Computing for Tactile Data Processing
Creators: name: YOUNES, HAMOUD
Publisher: name: Universit� degli studi di Genova
Year: 2022

description: Machine Learning (ML) a subset of Artificial Intelligence (AI) is driving the industrial and technological revolution of the present and future. We envision a world with smart devices that are able to mimic human behavior (sense, process, and act) and perform tasks that at one time we thought could only be carried out by humans. The vision is to achieve such a level of intelligence with affordable, power-efficient, and fast hardware platforms. However, embedding machine learning algorithms in many application domains such as the internet of things (IoT), prostheses, robotics, and wearable devices is an ongoing challenge. A challenge that is controlled by the computational complexity of ML algorithms, the performance/availability of hardware platforms, and the application?s budget (power constraint, real-time operation, etc.). In this dissertation, we focus on the design and implementation of efficient ML algorithms to handle the aforementioned challenges. First, we apply Approximate Computing Techniques (ACTs) to reduce the computational complexity of ML algorithms. Then, we design custom Hardware Accelerators to improve the performance of the implementation within a specified budget. Finally, a tactile data processing application is adopted for the validation of the proposed exact and approximate embedded machine learning accelerators. The dissertation starts with the introduction of the various ML algorithms used for tactile data processing. These algorithms are assessed in terms of their computational complexity and the available hardware platforms which could be used for implementation. Afterward, a survey on the existing approximate computing techniques and hardware accelerators design methodologies is presented. Based on the findings of the survey, an approach for applying algorithmic-level ACTs on machine learning algorithms is provided. Then three novel hardware accelerators are proposed: (1) k-Nearest Neighbor (kNN) based on a selection-based sorter, (2) Tensorial Support Vector Machine (TSVM) based on Shallow Neural Networks, and (3) Hybrid Precision Binary Convolution Neural Network (BCNN). The three accelerators offer a real-time classification with monumental reductions in the hardware resources and power consumption compared to existing implementations targeting the same tactile data processing application on FPGA. Moreover, the approximate accelerators maintain a high classification accuracy with a loss of at most 5%.
Chronic pain neuroscience and psychoanalytic theory a narrative review
Creators: name: Medina, Leonardo
Publisher: name: figshare
Year: 2022
Subjects: Health Care

description: Chronic pain is felt in the body and in the mind. S. Freud, J. Lacan, neurophysiologists, and societies for the study of pain have each explained it to us independently with little success when facing the complexity of this condition by patients and health personnel who care for them, but there are these theories, and you must begin to take them all into account to understand pain in its entirety. This review aims to describe the concept of chronic pain in a simple way and as an appetizer through, on the one hand, psychoanalytic theory and, on the other, neuroscience. In no way is it intended to equate psychoanalytic knowledge with neurobiological knowledge since their sources and scientific method are different. If similarities are found between both ways of understanding chronic pain, they should be understood as the author's opinions or the reader's deductions. What is desired here is to sow curiosity about the subject and in the future if it is possible to integrate the two ways of understanding long-term pain. For this narrative review, a manual and automated literature search was carried out in biomedical databases, disciplines related to neuroscience, psychoanalysis, and mental health, using search terms according to Medical Subject Headings. Textbooks on the topics and representative authors of psychoanalytic theory and neuroscience were also consulted. Although there are psychoanalytic and neurobiological approaches in the study of chronic pain, they all understand it independently, and their integration has not been achieved so far. However, we can get to know the bases of each aspect to venture into this company in the future. There is a need to increase research on chronic pain conditions, which correlates neurobiological and psychoanalytic aspects that contribute to achieving a multidimensional and effective treatment. It is especially urgent to find a way to "measure" psychoanalytic concepts to confirm them in the light of current scientific method.

description: We present a set of independent formulae to extract the gluon distribution and singlet structure function from its derivatives with respect to $lnQ^{2}$ in the next- to- leading order of perturbation theory at low-$x$ based on a hard pomeron exchange. In this approach, both singlet quarks and gluons have the same high-energy behavior at small $x$. This approach needs the QCD input parameterizations for a independent DGLAP evolutions that we calculated numerically and compared with MRST, GRV and DL model- the Pomeron has a hard nature. Its evolution gives a good fit to the experimental data. The obtained values are in the range $10^{-4}\hspace{0.1cm}{\leq}\hspace{0.1cm}x\hspace{0.1cm}{\leq}10^{-2}$ at $Q^{2}=20 \hspace{0.1cm}GeV^{2}$.

description: Managing critical infrastructures requires to increasingly rely on Information and Communi- cation Technologies. The last past years showed an incredible increase in the sophistication of attacks. For this reason, it is necessary to develop new algorithms for monitoring these infrastructures. In this scenario, Machine Learning can represent a very useful ally. After a brief introduction on the issue of cybersecurity in Industrial Control Systems and an overview of the state of the art regarding Machine Learning based cybersecurity monitoring, the present work proposes three approaches that target different layers of the control network architecture. The first one focuses on covert channels based on the DNS protocol, which can be used to establish a command and control channel, allowing attackers to send malicious commands. The second one focuses on the field layer of electrical power systems, proposing a physics-based anomaly detection algorithm for Distributed Energy Resources. The third one proposed a first attempt to integrate physical and cyber security systems, in order to face complex threats. All these three approaches are supported by promising results, which gives hope to practical applications in the next future.

description: We study thermal transport in the disordered Fermi liquid at low temperatures. Gravitational potentials are used as sources for finding the heat density and its correlation function. For a comprehensive study, we extend the renormalization group (RG) analysis developed for electric transport by including the gravitational potentials into the RG scheme. Our analysis reveals that the Wiedemann-Franz law remains valid even in the presence of quantum corrections caused by the interplay of diffusion modes and the electron electron interaction. In the present scheme this fundamental relation is closely connected with a fixed point in the multi-parametric RG-flow of the gravitational potentials.

description: We show that the nonlinear corrections to the longitudinal structure function can be tamed the singularity behavior at low x values, with respect to GLR-MQ equations. This approach can determined the shadowing longitudinal structure function based on the shadowing corrections to the gluon and singlet quark structure functions. Comparing our results with HERA data show that at very low x this behavior completely tamed by these corrections.

Classification of joinings for Kleinian groups

description: We classify all locally finite joinings of a horospherical subgroup action on Γ\ G when Γis a Zariski dense geometrically finite subgroup of G=PSL_2(R) or PSL_2(C). This generalizes Ratner's 1983 joining theorem for the case when Γis a lattice in G. One of the main ingredients is equidistribution of non-closed horospherical orbits with respect to the Burger-Roblin measure which we prove in a greater generality where G is the connected component of the identity in SO(n,1) for n at least 2 and Γis any Zariski dense geometrically finite subgroup of G.

description: Where do businesses source the capabilities that influence their diversification? From the resource-based perspective, capabilities are located within the firm. For many economic geographers, capabilities are place-based and flow between firms in local areas. Others claim the capabilities that count emerge from non-local collaboration. The value added of this paper is a firm–establishment–patent dataset that helps identify the sources of capabilities regulating technological diversification in the establishments of multi-locational firms. Results show that capabilities located within establishments themselves are most important to the process of diversification, followed by firm capabilities and then place-based capabilities.

description: The main objective of this deliverable is the theoretical development of quantum machine learning machinery for reinforcement learning, which is near-term-device friendly, yet sufficiently general to be applicable to the task of inventory management. This deliverable documents this achievement.
 With the advent of real-world quantum computing, the idea that parametrized quantum computations can be used as hypothesis families in a quantum-classical machine learning system is gaining increasing traction. Such hybrid quantum-classical systems, which use a classical loop over a parameterized quantum circuit, have already shown the potential to tackle real-world tasks in supervised and generative learning, and recent works have established their provable advantages in special artificial tasks. Yet, in the case of reinforcement learning, which is arguably most challenging and where learning boosts would be extremely valuable, no proposal has been successful in solving even standard benchmarking tasks, nor in showing a theoretical learning advantage over classical algorithms. In this work, we achieve both. We propose a hybrid quantum-classical reinforcement learning model using very few qubits, which we show can be effectively trained to solve several standard benchmarking environments. Moreover, we demonstrate, and formally prove, the ability of parametrized quantum circuits to solve certain learning tasks that are intractable to classical models, including current state-of-art deep neural networks, under the widely-believed classical hardness of the discrete logarithm problem. Our approach is general, and has shown applicable to both discrete and continuous state domains, with discrete actions, and is thus sufficiently general for application to the problem of inventory management. Furthermore, it is built around parametrized circuits, and is thus within the accepted paradigm for near-term-friendly proposals
On the diffraction by biperiodic anisotropic structures

description: This paper studies the scattering of electromagnetic waves by a nonmagnetic biperiodic structure. The structure consists of anisotropic optical materials and separates two regions with constant dielectric coefficients. The time harmonic Maxwell equations are transformed to an equivalent strongly elliptic variational problem for the magnetic field in a bounded biperiodic cell with nonlocal boundary conditions. This guarantees the existence of quasiperiodic magnetic fields in 퐻1 and electric fields in 퐻(curl) solving Maxwell's equations. The uniqueness is proved for all frequencies excluding possibly a discrete set. The analytic dependence of these solutions on frequency and incident angles is studied.
Momentum spectra of particles produced in a single pulse of an electric field

description: We study particle creation in a single pulse of an electric field in scalar quantum electrodynamics. We first identify parameter regions of the theory where the dynamical pair creation and Schwinger mechanism respectively dominate each other. Then, analytical expressions for the total characteristics of particle creation are determined for the case where the Schwinger mechanism dominates. We also compare our results with those produced in a constant electric field with a finite-time interval. These results coincide at a strong field regime, however they differ in general field strength. We identify the reason of this difference with a nonperturbative effect of high-frequency photons in external electric fields.
