Very true operators on MTL-algebras
Open Mathematics, 2016 The main goal of this paper is to investigate very true MTL-algebras and prove the completeness of the very true MTL-logic. In this paper, the concept of very true operators on MTL-algebras is introduced and some related properties are investigated. Also,

Neural Correlates of Apathy in Multiple System Atrophy: A Clinical and Perfusion Imaging Study
European Journal of Neurology, Volume 33, Issue 10, October 2026.In 76 patients with multiple system atrophy (MSA) and relatively preserved global cognition, apathy was present in 55.3%, with no association with motor severity or depressive symptoms. Reduced medial prefrontal cortex (mPFC) perfusion was independently associated with apathy after adjustment for clinical variables, while exploratory covariance ...

Mixed motives and linear forms in the Catalan constant
Journal of the London Mathematical Society, Volume 114, Issue 4, October 2026.Abstract We first give a geometric construction of a two‐dimensional mixed motive over Q${\mathbb {Q}}$ with the Catalan constant G=1−1/32+1/52−1/72+⋯${\mathbf {G}}=1-1/3^2+1/5^2-1/7^2+\cdots$ as a period. We then use this motive to obtain a supply of linear forms in 1 and G${\mathbf {G}}$.

Multiphysics Simulation of Positive Streamer Discharge in Air Using Finite Element Method
International Journal for Numerical Methods in Engineering, Volume 127, Issue 18, 30 September 2026.ABSTRACT Streamer discharge modeling by means of the Finite Element Method (FEM) presents a formidable challenge in computational physics due to its nonlinear and convection‐dominated characteristics that cause numerical instabilities, including negative densities of charged particles.

Conditional Measures on MV-algebras
Advances in Electrical and Electronic Engineering, 2004 In recent years many papers have been written generalizing some theorems, known from the Kolmogorovian probability theory, to MV-algebras. To achieve such results, so-called product MV-algebras were introduced and, using the product, the joint ...

Chorus Wave‐Induced Ionospheric Variability
Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.Abstract Electron microbursts are short‐lived but intense electron precipitation and constitute a significant source of electron losses into the ionosphere and lower atmosphere. They are primarily produced by wave‐particle interaction with chorus waves in the magnetosphere.

Exact Discrete Stochastic Simulation With Deep‐Learning‐Scale Gradient Optimization
Advanced Science, Volume 13, Issue 52, 18 September 2026.A 203,796‐parameter gene regulatory network classifies handwritten digits with 98.4% accuracy using exact stochastic dynamics. The framework decouples forward simulation from backward differentiation, making continuous‐time Markov chain models compatible with deep‐learning optimization.

Semantic Constructions for Hidden Algebra
, 1998 Hidden algebra is a behavioural algebraic specification formalism for objects. It captures their constructional aspect, concerned with the initialisation and evolution of their states, as well as their observational aspect, concerned with the observable ...

Improving the Empirical Formulae for CIE Daylight Illuminants
Color Research &Application, Volume 51, Issue 5, September/October 2026.CIE daylight illuminants (D‐Series) are widely used as reference illuminants for computing the color rendering index (Ra) and color fidelity index (Rf), yet the correlated color temperature (CCT) of the generated daylight SPD deviates from the specified value, with the error growing as CCT increases.

Engineering Reports, Volume 8, Issue 9, September 2026.The maximum heat transfer rate is observed at Ri = 10, Ha = 0, and ϕ = 0.06 under the default parameter settings for different boundary conditions. The proposed ANN model demonstrates good predictive and classification accuracy in estimating the average Nusselt number for both cases. ABSTRACT This computational study introduces a novel hybrid framework
