An effective Bombieri–Vinogradov error term for sifting problems
Mathematika, Volume 72, Issue 4, October 2026.Abstract In number theory, many major results related to the additive properties of primes are proven using the methods of sieve theory. However, in nearly every case, the existing proofs of these results are ineffective, in that explicit values for which they hold cannot be computed.

Algebraic Quantum Field Theory [PDF]
, 2006 Algebraic quantum field theory provides a general, mathematically precise description of the structure of quantum field theories, and then draws out consequences of this structure by means of various mathematical tools -- the theory of operator algebras,

International Journal for Numerical Methods in Engineering, Volume 127, Issue 17, 15 September 2026.ABSTRACT Predicting structural lifetime under complex loading remains a major challenge in computational mechanics, especially for high cycle fatigue in large scale systems such as aircraft, bridges, and wind turbines. This difficulty arises from the need to capture fatigue damage accumulation, crack initiation, crack growth across scales, and life ...

Mechanistic Insights Into the Thermal Pyrolysis of Branched Polyolefins Using Kinetic Modeling
ChemSusChem, Volume 19, Issue 17, 14 September 2026.We present a detailed mechanistic analysis of thermal pyrolysis of linear and branched polyolefins. The pyrolytic pathways in high‐density polyethylene (HDPE), polypropylene (PP), and linear low‐density polyethylene (LLDPE) are compared. The mechanistic model for LLDPE is newly developed, based on the population balance approach incorporating reactions

Quantum‐Like Dynamics in Whole‐Brain Models of the Human Connectome
Advanced Science, Volume 13, Issue 51, 14 September 2026.Quantum‐like dynamics in the human brain. The level of quantum‐like behavior in a non‐quantum system of coupled oscillators is regulated by the spectral gap of the coupling graph. Whole‐brain modelling using QL fits the empirical data significantly better and has a lower model‐derived energy cost than the non‐QL model.

Petri Nets for Automatic Wave Digital Code Generation
International Journal of Numerical Modelling: Electronic Networks, Devices and Fields, Volume 39, Issue 5, September/October 2026.ABSTRACT Wave Digital (WD) models are a well‐established framework for the emulation of linear and nonlinear circuits. In practice, however, WD models are still implemented largely manually or through limited automated toolchains. Manual programming of WD models is time‐consuming and error‐prone for larger systems with pronounced algebraic dependencies,

Predicting the Toxicity of Chemical Compounds via Hyperdimensional Computing
Molecular Informatics, Volume 45, Issue 9, September 2026.Hyperdimensional computing converts text representations of chemical structures (SMILES) into high‐dimensional vectors. New compounds are classified by comparison with learned toxic and nontoxic reference patterns; across 12 Tox21 targets, overlapping four‐character SMILES patterns performed best among tested representations, supporting fast ...
