Spectral Parameter Power Series for Zakharov‐Shabat Direct and Inverse Scattering Problems

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT We study the direct and inverse scattering problems for the Zakharov‐Shabat system. Representations for the Jost solutions are obtained in the form of the power series in terms of a transformed spectral parameter. In terms of that parameter, the Jost solutions are convergent power series in the unit disk.

The importance of integrating herbarium records into conservation plans: a case study on Honduran ferns and lycophytes

PLANTS, PEOPLE, PLANET, EarlyView.
Herbarium collections are powerful, yet underutilized, tools for global biodiversity conservation and protected area management. By integrating digitized herbarium records with existing biodiversity data, previously unknown plant species were uncovered, exposing critical gaps in conservation knowledge.

Citizen science informs demand‐driven breeding of opportunity crops

PLANTS, PEOPLE, PLANET, EarlyView.
Amid global challenges of food insecurity, poor nutrition, and climate change, neglected crops like amaranth are gaining renewed attention. We studied farmers' preferences for amaranth varieties across diverse geographical contexts to guide targeted breeding.

Almost Everywhere Convergence of Varying Parameter Setting Cesàro Means of Fourier Series With Respect to Walsh–Kaczmarz System

Annales Mathematicae Silesianae
In this paper, the almost everywhere convergence of Cesàro means of Walsh–Kaczmarz–Fourier series in a varying parameter setting is investigated. In particular, we define subsequence ℕαn,q{{\mathbb{N}}_{{{\alpha }_{n}},q}} of natural numbers and prove ...

Citizen science data reveals winter warming delays cherry bloom in the Pacific Northwest, USA

PLANTS, PEOPLE, PLANET, EarlyView.
Climate change is altering ecological systems, including the phenology of flowering plants. Shifts in the bloom date of cherry trees are a global concern considering their cultural, agricultural, and horticultural importance. Ornamental cherry is a prominent component of the University of Washington campus (Seattle, USA), providing an opportunity to ...
