Uniqueness Criteria For Inverse Scattering Problem In Terms Of Transmission Matrix In Boundary Condition For A First Order System Of Ordinary Differential Equations, Gebze Technical University, Kocaeli, T¨Urkiye, M.I. Ismailov, Cihan Sabaz

Baku Mathematical Journal

The inverse scattering problem (ISP) involves the recovery of the matrix coefficient of a first-order system on the half-line from its scattering matrix. Specifically, when the matrix coefficient exhibits a triangular structure, the system possesses a Volterra-type integral transformation operator at infinity. This transformation operator facilitates the determination of the scattering matrix on the half-line through matrix Riemann-Hilbert factorization. Solving the ISP on the half-line entails reducing it to an ISP on the whole line for the considered system. This reduction involves extending the coefficients to the whole line by zero. The uniqueness criteria in terms of transmission matrix in …

On Combining The Stages Of Parametric Identification And Optimization Of Dynamic Processes, Azerbaijan State Oil And Industry University, Samir Guliyev, Seymur Mirzabayov

Baku Mathematical Journal

In the paper, we propose a method for jointly solving problems of parametric identification of a mathematical model’s parameters and searching for the optimal mode of a dynamic object. As a result of this joint process, we obtain a suboptimal solution to the problem of controlling a dynamic object in the vicinity of the optimal mode. We present computation formulas and algorithms for implementing the proposed approach, as well as the results of computer-based experiments.

A Multiscale Approach To Understanding The Shared Blue-Orange Flower Color Polymorphism In Two Lysimachia Species, Mercedes Sánchez-Cabrera, Eduardo Narbona, Montserrat Arista, Pedro L. Ortiz, Francisco J. Jiménez-López, Amelia A. Fuller, Benjamin Carter, Justen B. Whittall

Chemistry and Biochemistry

Background
Polymorphisms are common in nature, but they are rarely shared among closely related species. Polymorphisms could originate through convergence, ancestral polymorphism, or introgression. Although shared neutral genomic variation across species is commonplace, few examples of shared functional traits exist. The blue-orange petal color polymorphisms in two closely related species, Lysimachia monelli and L. arvensis were investigated with UV-vis reflectance spectra, flavonoid biochemistry, and transcriptome comparisons followed by climate niche analysis.

Results
Similar color morphs between species have nearly identical reflectance spectra, flavonoid biochemistry, and ABP gene expression patterns. Transcriptome comparisons reveal two orange-specific genes directly involved in both blue-orange …

Robust And Generalizable Representations In The Hippocampus, Hung-Tu Chen

Dartmouth College Ph.D Dissertations

An intelligent system must balance generalizing across similar experiences with maintaining the distinctiveness of each experience. This thesis explores how the hippocampus manages this balance through its neural representations to support adaptive behavior. In Chapter 1, I provide an overview of key hippocampal phenomena that contribute to this process, including remapping, splitter signal, and replay. In Chapter 2, I challenge the concept of random remapping by showing that it is possible to predict, better than chance, how a given experience will be encoded in the hippocampus across different subjects. This suggests that encoding of related experiences, which was previously thought …
