A Perspective on the Foundations of Derived Analytic Geometry [PDF]
arXivWe show how one can do algebraic geometry with respect to the category of simplicial objects in an exact category. As a biproduct, we get a theory of derived analytic geometry.

Filtration enlargement‐based time series forecast in view of insider trading
Journal of Economic Surveys, Volume 37, Issue 1, Page 112-140, February 2023., 2023 Abstract This survey reviews filtration enlargement models in view of insider trading. Although filtration enlargement aptly models insiders' informational advantage, the theoretical results have not attracted the attention of the empiricists, owing mainly to the lack of a bridge transforming the results to testable hypotheses, and/or the absence of ...

Multi‐Slit Diffraction in Scaled Space‐Time
Natural Sciences, EarlyView.A space‐time scaling is used to transform quantum wave packets describing free particle motion to packets moving in an effective harmonic oscillator potential that confines and directs the wave fronts along the classical phase space of the oscillator. The transformation is applied to multi‐slit diffraction and shown to characterize diffraction features

Psychology in the Schools, EarlyView.ABSTRACT Cyberbullying is an increasingly researched topic in the field of adolescence, largely due to its pervasiveness and negative wellbeing outcomes for victims. However, existing literature in this area largely focuses on those aged above 13 years, despite evidence suggesting that early adolescents (ages 10–13) also experience victimization ...

Windowed Green function method for wave scattering by periodic arrays of 2D obstacles
Studies in Applied Mathematics, Volume 150, Issue 1, Page 277-315, January 2023., 2023 Abstract This paper introduces a novel boundary integral equation (BIE) method for the numerical solution of problems of planewave scattering by periodic line arrays of two‐dimensional penetrable obstacles. Our approach is built upon a direct BIE formulation that leverages the simplicity of the free‐space Green function but in turn entails evaluation ...

Advanced Quantum Technologies, EarlyView.The hybrid approach to Quantum Supervised Machine Learning is compatible with Noisy Intermediate Scale Quantum (NISQ) devices but hardly useful. Pure quantum kernels requiring fault‐tolerant quantum computers are more promising. Examples are kernels computed by means of the Quantum Fourier Transform (QFT) and kernels defined via the calculation of ...

Reproducing the Effects of Quantum Deformation in the Undeformed Jaynes‐Cummings Model
Advanced Quantum Technologies, EarlyView.The inverse problem approach, where atomic probabilities are modulated according to a time‐dependent coupling, is studied for the Jaynes‐Cummings (JC) model. In particular, emphasis is placed on how to reproduce the effects of quantum deformation in a non‐deformed JC model.

Open and Closed Loop Approaches for Energy Efficient Quantum Optimal Control
Advanced Quantum Technologies, EarlyView.Concepts from quantum thermodynamics and optimal control are blended to derive a theoretical framework to quantify and minimize the energetic cost of a pulse for unitary synthesis. Two complementary techniques (based on GRAPE and Reinforce‐DRL) are implemented as open‐source software that co‐optimizes the fidelity and energetic cost within quantum ...

Towards a Semiautonomous Young Spruce Forest Late Cleaning
Journal of Field Robotics, EarlyView.ABSTRACT Cleaning a seedling spruce stand is an important silvicultural task required to help the young spruce trees thrive. It is usually manual work with a clearing saw. Mechanized solutions have been proposed, but they have not worked out well, since the driver has challenges in seeing the seedling trees that should be left growing.
