Nonlinear Effects on the Convergence of Picard and Newton Iteration Methods in the Numerical Solution of One-Dimensional Variably Saturated–Unsaturated Flow Problems

open access: yesHydrology, 2017
Finite element discretization of the pressure head form of the Richards equation leads to a nonlinear model, which yields numerical convergence difficulties.

‘Unbecoming’ a Professional: The Role of Memory during Field Transitions in Japan and the USA

open access: yesJournal of Management Studies, EarlyView.
Abstract Existing scholarship documents how, in becoming a professional, such as a partner in a professional services firm (PSF), one's habitus comes into alignment with field expectations. Less understood, however, is what happens to habitus and, relatedly, to professionals' accumulated cultural, social, and economic capitals, as individuals ‘unbecome’

Endogenous Distress Contagion in a Dynamic Interbank Model: How Possible Future Losses May Spell Doom Today

open access: yesMathematical Finance, EarlyView.
ABSTRACT We introduce a dynamic and stochastic interbank model with an endogenous notion of distress contagion, arising from rational worries about future defaults and ensuing losses. This entails a mark‐to‐market valuation adjustment for interbank claims, leading to a forward‐backward approach to the equilibrium dynamics whereby future default ...

Function Art: Linking Mathematics, Technology, and Visual Arts

open access: yesSchool Science and Mathematics, EarlyView.
ABSTRACT This study investigated students' understanding of mathematical functions and strategies to create artwork using GeoGebra. It was framed by the principles of constructionism and examined how students use functions in creating artworks. We gathered data from students' artworks using the Algebra view and the Construction Protocol in the GeoGebra

Comparison of the Rate of Convergence among Picard, Mann, Ishikawa, and Noor Iterations Applied to Quasicontractive Maps

open access: yesFixed Point Theory and Applications, 2010
We provide sufficient conditions for Picard iteration to converge faster than Krasnoselskij, Mann, Ishikawa, or Noor iteration for quasicontractive operators.

Existence and attractivity of solutions for fractional difference equations

open access: yesAdvances in Difference Equations, 2018
In this paper, we study a kind of difference equations with Riemann–Liouville-like fractional difference. The results on existence and attractivity are obtained by using the Picard iteration method and Schauder’s fixed point theorem.

Ligand‐driven modulation of chaperone–cochaperone networks shapes proteostasis outcomes

open access: yesProtein Science, Volume 35, Issue 5, May 2026.
Abstract Protein homeostasis depends on a delicate interplay between folding and degradation, orchestrated by molecular chaperones. Among them, Hsp90 is a central hub, regulating nearly 10% of the proteome through ATP‐driven conformational cycles and selective interactions with cochaperones.

Intercolony and Intra‐Annual Variations in Isotopic Niche of Red‐Footed Boobies Sula sula in the Tropical Indian Ocean

open access: yesEcological Research, Volume 41, Issue 3, May 2026.
We compared the diet and assessed geographic and seasonal variations in the isotopic niches of red‐footed boobies across three Indian Ocean atolls. Our results demonstrate plasticity in both diet and trophic niche, likely driven by local environmental conditions, breeding stages, and colony‐specific factors.

At the Right Time: Temporal Precision in Personalised Medicine

open access: yesSociology of Health &Illness, Volume 48, Issue 4, May 2026.
ABSTRACT Personalised medicine was initially heralded as delivering ‘the right drug to the right patient at the right time’. Although molecular precision has dominated recent developments, the temporal dimension has remained underexplored. This paper examines how temporal precision is emerging as a defining feature of next‐generation precision medicine,
