Kinetic Model of Translational Autoregulation

open access: yes, 2018
We investigate dynamics of a kinetic model of inhibitory autoregulation as exemplified when a protein inhibits its own production by interfering with its messenger RNA, known in molecular biology as translational autoregulation.

A new species of Lonchidiidae (Hybodontiformes) from the Late Jurassic of Brazil (Aliança Formation, Jatobá Basin)

open access: yesThe Anatomical Record, EarlyView.
Abstract The Aliança Formation (Jatobá Basin) represents lacustrine deposits formed in oxygenated waters that hosted a diverse fauna, including Hybodontiform sharks. Within this group, the Family Lonchidiidae comprises 11 valid genera, with Parvodus previously reported in Brazilian deposits from the Brejo Santo Formation (Araripe Basin, Late Jurassic ...

Effect of Random Parameter Switching on Commensurate Fractional Order Chaotic Systems

open access: yes, 2016
The paper explores the effect of random parameter switching in a fractional order (FO) unified chaotic system which captures the dynamics of three popular sub-classes of chaotic systems i.e. Lorenz, Lu and Chen's family of attractors.

Axion-Dilaton Domain Walls and Fake Supergravity

open access: yes, 2007
Dynamical systems methods are used to investigate domain-wall solutions of a two-parameter family of models in which gravity is coupled to an axion, and to a dilaton with an exponential potential of either sign.

Data, not documents: Moving beyond theories of information‐seeking behavior to advance data discovery

open access: yesJournal of the Association for Information Science and Technology, Volume 76, Issue 4, Page 649-664, April 2025.
Abstract Many theories of human information behavior (HIB) assume that information objects are in text document format. 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.

Classification of global phase portraits and bifurcation diagrams of Hamiltonian systems with rational potential

open access: yesJournal of Differential Equations, 2016
The authors find all possible phase portraits, up to topological equivalence, of vector fields of the form \(\dot x = H_y\), \(\dot y = -H_x\), where the Hamiltonian has the form \(H = \frac12 y^2 + P(x) / Q(x)\) and \(P\) and \(Q\) are polynomials of degree at most two.

Immersive reality capabilities of relieving hiraeth

open access: yesJournal of the Association for Information Science and Technology, EarlyView.
Abstract Understanding how immersive experiences foster a sense of presence sufficient to rival real‐world experiences remains an open research area. Prior work has largely examined episodic memory recall in simulated environments, but less is known about how immersive technologies can reconnect individuals with personal memories.

Hidden Attractors in a New 4D Memristor-Based Hyperchaotic System: Dynamical Analysis, Circuit Design, Synchronization, and Its Applications

open access: yesMathematics
This paper presents a novel four-dimensional (4D) memristive system, notable for its simplicity and unique dynamic behaviors. Comprising only seven terms and devoid of equilibrium points, this system is capable of generating hidden attractors.

Developing a critical caste analysis within information science and technology: A research review: An annual review of information science and technology paper

open access: yesJournal 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.

Opposing consensus science through scholarly practices: The role of claims maintenance

open access: yesJournal of the Association for Information Science and Technology, EarlyView.
Abstract This study examines how three US‐based communities who oppose consensus science produce and disseminate scholarly‐like artifacts: pro‐life activists, Young Earth Creationists, and Anthropogenic Climate Crisis skeptics. Prior research shows that industry‐ or church‐backed advocacy campaigns often generate claims supported by these communities ...
