Srinivasa Ramanujan: His Life, Legacy, and Mathematical Influence,
2024 by Krishnaswami Alladi (Editor), George E. Andrews (Editor), Bruce C.
Berndt (Editor), Frank Garvan (Editor), Ken Ono (Editor)The overlap of Srinivasa Ramanujan's work with quantum field theory is discussed. A mathematically natural axiom for euclidean quantum field theories is proposed.

Advanced Photonics Research, EarlyView.Ultrafast pulsed laser technology enables precise material processing. This study examines molybdenum oxide formation under varying laser parameters. A dataset of 187 samples is generated, and eight deep neural networks (DNNs) with different architectures are trained. Models are validated using three learning rates and evaluated with mean squared error,

On the bracket problem in covariant Hamiltonian field theory [PDF]
arXiv, 1999 The polysymplectic phase space of covariant Hamiltonian field theory can be provided with the current algebra bracket.
arxiv
Advanced Photonics Research, EarlyView.Multiple incoherent nonlinear deconvolutions (MIND) has extended dimension for optimization that provides a better solution than Wiener deconvolution and nonlinear reconstruction. MIND minimizes deconvolution noise by averaging over multiple deconvolutions each with different system aperture that effectively enhances the resolution.

Twin neural network regression
Applied AI Letters, Volume 3, Issue 4, December 2022., 2022 We propose to reformulate a regression problem into predicting differences between target values. This allows for leveraging consistency conditions which can be used as uncertainty estimates and enable the production of an ensemble of predictions while training only a single neural network.

The bracket and the evolution operator in covariant Hamiltonian field theory [PDF]
arXiv, 2002 No bracket determines the evolution operator in covariant (polysymplectic and multisymplectic) Hamiltonian field theory.

Advanced Photonics Research, EarlyView.An enhanced homogenization method for periodic lattices, applicable to any asymmetrical multipart structures, is proposed. This method simplifies intricate gratings into slab waveguides, predicts guided‐mode resonances and bound states in the continuum, without relying on numerical methods.
