Dynamics of the Isotropic Star Differential System from the Mathematical and Physical Point of Views
AppliedMathThe following differential quadratic polynomial differential system dxdt=y−x, dydt=2y−yγ−12−γy−5γ−4γ−1x, when the parameter γ∈(1,2] models the structure equations of an isotropic star having a linear barotropic equation of state, being x=m(r)/r where m ...

This paper argues four important HIB theories are insufficient for describing users' search strategies for data because of assumptions about the attributes of objects that users seek.

Phase portraits of Bernoulli quadratic polynomial differential systems
Electronic Journal of Differential Equations, 2020 In this article we study a new class of quadratic polynomial differential systems. We classify all global phase portraits in the Poincare disk of Bernoulli quadratic polynomial differential systems in R^2.

Journal of the Association for Information Science and Technology, EarlyView.Abstract Caste—an ascriptive social hierarchy in South Asia and its diaspora—is a globalized phenomenon. Recent caste‐based discrimination, particularly in technology companies and anti‐caste efforts to address it, has compelled academia, policy, and the technology industry to better understand contemporary mechanics of caste.

Journal of the Association for Information Science and Technology, EarlyView.Abstract This review analyzed 241 scholarly articles published between 2010 and 2025 in information science venues to examine how affect shapes refugees' information behavior during forced migration and to identify additional contextual factors. It identifies seven affective dimensions: anxiety, shame and stigma, grief and loss, frustration, (mis)trust,

Any old Tom, Dick, or Harry: The citation impact of author first name genderedness
Journal of the Association for Information Science and Technology, EarlyView.Abstract This paper examines the relationship between the genderedness of authors' first names and citation distributions in US‐affiliated scholarly production from 2010 to 2019. Merging a first name genderedness table derived from Wikidata with Web of Science publication data, we develop a relative distributional framework that compares first name ...
