Generalized Modified Unstable Nonlinear Schrödinger’s Equation: Optical Solitons and Modulation Instability

Mathematics
This paper proposes the generalized modified unstable nonlinear Schrödinger’s equation with applications in modulated wavetrain instabilities. The extended direct algebra and generalized Ricatti equation methods are applied to find innovative soliton ...

Symmetry‐Imposed Selection Rules for Excitations of Nontrivial Plasmonic Topologies

Advanced Science, EarlyView.
A unified group‐theory selection rule governs the excitation of vectorial nearfield topologies across three plasmonic spin states. Derived from first principles, it predicts spin–orbit vortex splitting and multidimensional nested vortices, confirmed by phase‐resolved in situ measurements.

A global theory of algebras of generalized functions II: tensor distributions

, 2012
We extend the construction of [19] by introducing spaces of generalized tensor fields on smooth manifolds that possess optimal embedding and consistency properties with spaces of tensor distributions in the sense of L. Schwartz.

Note on Generalizations of Orthocomplete and Lattice Effect Algebras [PDF]

International Journal of Theoretical Physics, 2011
An effect algebra is a partial algebra \(E=(E;\oplus,0,1)\) such that, for all \(a,b,c \in E\), we have (i) \(\oplus\) is commutative and associative, (ii) given \(a \in E\), there is a unique element \(a'\in E\) such that \(a\oplus a'=1\), and (iii) if \(a\oplus 1\) is defined, then \(a=0\).

DMA:an algebra for multicriteria spatial modeling [PDF]

, 2006
The objective of this paper is to propose a new algebra, called decision map algebra (DMA), especially devoted to multicriteria spatial modeling. DMA is a generic and context-independent modeling language inspired from map algebra and other similar ...

Tau Aggregate Imaging and Transcriptomics of Alzheimer's Disease Brain at Different Stages of Disease

Advanced Science, EarlyView.
The protein aggregates and gene expression in the middle temporal gyrus (MTG) and somatosensory cortex (SOM) of the postmortem brains of 13 Alzheimer's disease patients were studied in detail, revealing that small hyperphosphorylated tau aggregates increase with Braak stage driven by microglial inflammation.

Common Generalizations of Orthocomplete and Lattice Effect Algebras [PDF]

International Journal of Theoretical Physics, 2009
In [\textit{P. G. Ovchinnikov}, ``On alternative orthomodular posets'', Demonstr. Math. 27, No.~1, 89--93 (1994; Zbl 0808.03046)], a certain class of orthomodular posets was introduced as a common generalization of orthomodular posets and orthomodular lattices.

The exocenter and type decomposition of a generalized pseudoeffect algebra [PDF]

, 2013
We extend the notion of the exocenter of a generalized effect algebra (GEA) to a generalized pseudoeffect algebra (GPEA) and show that elements of the exocenter are in one-to-one correspondence with direct decompositions of the GPEA; thus the exocenter ...

Seeing the Chemistry of Biomolecular Condensates: In Situ Mapping of Composition and Water Content

Advanced Science, EarlyView.
Raman hyperspectral imaging combined with spectral phasor analysis enables a label‐free quantification of proteins, polymers and water density within individual biomolecular condensates. By transforming complex vibrational fingerprints into intuitive compositional maps, the approach reveals the high water content and structural heterogeneity of ...

Updatable Closed‐Form Evaluation of Arbitrarily Complex Multiport Network Connections

Advanced Electronic Materials, EarlyView.
The inverse design of electrically large wave devices often uses reduced‐order multiport models with discrete optimization, requiring many evaluations of complex interconnections between subsystems that differ only in a few blocks. This paper introduces a closed‐form framework enabling efficient Woodbury low‐rank updates of related, previous ...
