A local inverse formula and a factorization

open access: yes, 2018
© Springer International Publishing AG, part of Springer Nature 2018. All rights reserved. When a matrix has a banded inverse there is a remarkable formula that quickly computes that inverse, using only local information in the original matrix.

Closed-Form Formula for the Conditional Moments of Log Prices under the Inhomogeneous Heston Model

open access: yes, 2022
Several financial instruments have been thoroughly calculated via the price of an underlying asset, which can be regarded as a solution of a stochastic differential equation (SDE), for example the moment swap and its exotic types that encourage investors

Compatibility of Methacrylate Based Resins Controls Interfacial Failure and Toughness in 3D‐Printed Multimaterial Composites

open access: yesAdvanced Engineering Materials, EarlyView.
This work shows that the mechanical performance of multimaterial digital light processing (DLP) printed thermoset composites is governed by resin compatibility and interfacial design rather than spatial patterning alone. Brittle and ductile resin combinations produced premature interfacial failure, while graded interfaces and mechanically compatible ...

Computing distinguishing formulas for branching bisimulation [PDF]

open access: yes, 1992
Branching bisimulation is a behavioral equivalence on labeled transition systems which has been proposed by Van Glabbeek and Weijland as an alternative to Milner's observation equivalence. This paper presents an algorithm which, given two branching bisimulation inequivalent finite state processes, produces a distinguishing formula in Hennessy-Milner ...

Printed Integrated Logic Circuits Based on Chitosan‐Gated Organic Transistors for Future Edible Systems

open access: yesAdvanced Functional Materials, EarlyView.
Edible electronics needs integrated logic circuits for computation and control. This work presents a potentially edible printed chitosan‐gated transistor with a design optimized for integration in circuits. Its implementation in integrated logic gates and circuits operating at low voltage (0.7 V) is demonstrated, as well as the compatibility with an ...

A More Efficient Conditional Private Preservation Scheme in Vehicular Ad Hoc Networks

open access: yesApplied Sciences, 2018
It is a challenging issue to provide a secure and conditional anonymous authentication scheme in vehicle ad hoc networks (VANETs) with low storage space and computational cost. In 2008, Lu et al.

Efficient Volume Computation for SMT Formulas

open access: yesProceedings of the TwentySecond International Conference on Principles of Knowledge Representation and Reasoning
Satisfiability Modulo Theory (SMT) has recently emerged as a powerful tool for solving various automated reasoning problems across diverse domains. Unlike traditional satisfiability methods confined to Boolean variables, SMT can reason on real-life variables like bitvectors, integers, and reals.

Ferroelectricity in Antiferromagnetic Wurtzite Nitrides

open access: yesAdvanced Functional Materials, EarlyView.
We establish MnSiN2${\rm MnSiN}_2$ and MnGeN2${\rm MnGeN}_2$ as aristotypes of a new multiferroic wurtzite family that simultaneously exhibits ferroelectricity and antiferromagnetism with altermagnetic spin splitting. By strategically substituting alkaline‐earth metals, we predict new materials with coexisting switchable polarization, spin texture, and

Computational and Memory Efficiency in Heartbeat Rate Detection: A Review of ECG and PPG Techniques

open access: yesSensors
(1) Background: Heartbeat detection from electrocardiogram (ECG) and photoplethysmograph (PPG) signals is widely used in wearable devices for health monitoring, fitness tracking, and stress assessment.

Reduced-Order Modelling and Homogenisation in Magneto-Mechanics: A Numerical Comparison of Established Hyper-Reduction Methods

open access: yesMathematical and Computational Applications, 2019
The simulation of complex engineering structures built from magneto-rheological elastomers is a computationally challenging task. Using the FE 2 method, which is based on computational homogenisation, leads to the repetitive solution of micro ...
