Updates, Examples and Validation of the Global Ionosphere Thermosphere Model
Space Weather, Volume 24, Issue 5, May 2026.Abstract This study provides an updated description, example simulations, and validation of the Global Ionosphere Thermosphere Model (GITM). The updates to GITM include using an exothermic semi‐implicit chemistry scheme that no longer requires an altitude dependent heating efficiency; an ionospheric wind‐driven dynamo; improved neutral, ion, and ...

Machine Learning Discovery of Record‐Low Lattice Thermal Conductivity in Double Perovskites
Advanced Science, Volume 13, Issue 18, 27 March 2026.A deep learning interatomic potential is introduced to predict forces for computing phonon properties and thermal transport behavior in double perovskites. Screening 9,709 compounds identifies 1,597 stable materials, and Boltzmann transport calculations including both three and four‐phonon scattering suggests a record‐low lattice thermal conductivity ...

Tunable active-phase-compensated universal biquadratic filter
Electronics Letters, 1980 A tunable active-phase-compensated universal biquadratic filter is presented. It is shown that for the matched amplifiers the circuit not only exhibits stable Q-factor but also tracks the pole-zero frequencies. The proposed circuit provides simultaneously four basic biquadratic realisations—notch, lowpass, highpass and bandpass.

A New Voltage-Mode Universal Biquadratic Filter Using Single UVC
Circuits and Systems, 2017 The paper presents a new universal biquadratic filter using single universal voltage conveyor (UVC), two resistors and two capacitors. The offered structure has three inputs and one output and can realise all the five basic biquadratic filters: high-pass (HP), low-pass (LP), band-reject (BR), band-pass (BP) and all-pass (AP) from the same circuit ...

Equivariant toric geometry and Euler–Maclaurin formulae
Communications on Pure and Applied Mathematics, Volume 79, Issue 3, Page 451-557, March 2026.Abstract We first investigate torus‐equivariant motivic characteristic classes of toric varieties, and then apply them via the equivariant Riemann–Roch formalism to prove very general Euler–Maclaurin‐type formulae for full‐dimensional simple lattice polytopes.

Review of Flash Joule Heating for the Synthesis of Graphene and Other Functional Carbon Materials
Carbon Energy, Volume 8, Issue 1, January 2026.ABSTRACT Flash Joule heating (FJH), as a high‐efficiency and low‐energy consumption technology for advanced materials synthesis, has shown significant potential in the synthesis of graphene and other functional carbon materials. Based on the Joule effect, the solid carbon sources can be rapidly heated to ultra‐high temperatures (> 3000 K) through ...

IET Intelligent Transport Systems, Volume 20, Issue 1, January/December 2026.This study proposes a tolerance lexicographic optimization framework for Connected and Automated Heavy Vehicles (CAHV) to achieve safe, efficient, and eco‐friendly trajectory planning on freeways. The method dynamically balances multiple objectives and accounts for surrounding Manual Vehicle (MV) behaviors.
