Spintronic Memtransistor Leaky Integrate and Fire Neuron for Spiking Neural Networks
Advanced Electronic Materials, EarlyView.Spintronic memtransistor neurons based on domain walls enable energy‐efficient, field‐gated, and current‐controlled LIF functionality for neuromorphic computing, as demonstrated. When integrated into spiking neural network architectures, these devices achieve >96% pattern recognition accuracy, demonstrating high performance, scalability, and mem ...

International Journal for Numerical Methods in Engineering, Volume 124, Issue 2, Page 402-433, 30 January 2023., 2023 Abstract Edge‐based and face‐based smoothed finite element methods (ES‐FEM and FS‐FEM, respectively) are modified versions of the finite element method allowing to achieve more accurate results and to reduce sensitivity to mesh distortion, at least for linear elements. These properties make the two methods very attractive. However, their implementation

Sustainable Thermal Solutions: Enhancing Heat Transfer with Turbulators and Nanofluids
Advanced Energy and Sustainability Research, EarlyView.Nanofluids, which are nanoparticle suspensions in base fluid, facilitate heat transmission due to their improved thermal conductivity. Turbulators, which are inserts into fluid flow channels, disturb the flow, increasing turbulence and hence the heat transfer rate.

Efficient formulation of a two‐noded geometrically exact curved beam element
International Journal for Numerical Methods in Engineering, Volume 124, Issue 3, Page 570-619, 15 February 2023., 2023 Abstract The article extends the formulation of a 2D geometrically exact beam element proposed by Jirásek et al. (2021) to curved elastic beams. This formulation is based on equilibrium equations in their integrated form, combined with the kinematic relations and sectional equations that link the internal forces to sectional deformation variables.

Transverse Vibration of Rotating Tapered Cantilever Beam with Hollow Circular Cross-Section
Shock and Vibration, 2018 Problems related to the transverse vibration of a rotating tapered cantilever beam with hollow circular cross-section are addressed, in which the inner radius of cross-section is constant and the outer radius changes linearly along the beam axis.

An outline of shifted Poisson structures and deformation quantisation in derived differential geometry [PDF]
arXiv, 2018 We explain how to translate several recent results in derived algebraic geometry to derived differential geometry. These concern shifted Poisson structures on NQ-manifolds, Lie groupoids, smooth stacks and derived generalisations, and include existence and classification of various deformation quantisations.

Analytic Hochschild-Kostant-Rosenberg Theorem [PDF]
arXiv, 2021 Let $R$ be a Banach ring. We prove that the category of chain complexes of complete bornological $R$-modules (and several related categories) is a derived algebraic context in the sense of Raksit. We then use the framework of derived algebra to prove a version of the Hochschild-Kostant-Rosenberg Theorem, which relates the circle action on the ...

Conformal maps in higher dimensions and derived geometry [PDF]
arXiv, 2021 By Liouville's theorem, in dimensions 3 or more conformal transformations form a finite-dimensional group, an apparent drastic departure from the 2-dimensional case. We propose a derived enhancement of the conformal Lie algebra which is an infinite-dimensional dg-Lie algebra incorporating not only symmetries but also deformations of the conformal ...

Full‐order observer design for quadratic port‐controlled Hamiltonian systems
Asian Journal of Control, EarlyView.Abstract The full‐order observer design problem for a particular class of port‐controlled Hamiltonian systems is approached in this paper. The proposed full‐order observer scheme belongs to the structure preserving class of dynamic estimators as it preserves the natural stability properties of the approached class of systems that are useful for the ...

Lectures on shifted Poisson geometry [PDF]
arXiv, 2017 These are expanded notes from lectures given at the \'{E}tats de la Recherche workshop on "Derived algebraic geometry and interactions". These notes serve as an introduction to the emerging theory of Poisson structures on derived stacks.
