Power bounded prolongations and Picard-Lindel�f iteration

open access: yesNumerische Mathematik, 1990
The author continues several earlier studies of Picard-Lindelöf iteration of linear constant coefficient systems \(\dot x+Ax=f(t),\) \(x(0)=x_ 0\), where the matrix A is assumed to be split as \(A=M-N\) for iteration \(\dot x^ n+Mx^ n=Nx^{n-1}+f(t),\) \(x^ n(0)=x_ 0\) [see e.g. the author, ibid. 57, No.2, 147-156 (1990; Zbl 0697.65058)].

A Phase II Trial of Perioperative Camrelizumab Plus Neoadjuvant Chemotherapy in Resectable Stage IIB–IIIB Lung Squamous Cell Carcinoma

open access: yesMedComm, Volume 7, Issue 7, July 2026.
This phase II trial suggests the potential of perioperative camrelizumab plus neoadjuvant chemotherapy in patients with resectable stage IIB‐IIIB lung squamous cell carcinoma. The major pathological response rate (primary endpoint) was 60.0%, and the pathological complete response (pCR) rate was 44.4%.

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.

Leading Otherwise: Feminist Instances From the Arts

open access: yesGender, Work &Organization, Volume 33, Issue 4, Page 1196-1209, July 2026.
ABSTRACT This paper explores how feminist artists enact leadership through artistic organizing in the creative industries. Drawing on two case studies—Company Drinks and Homebaked—it examines how leadership emerges not through formal roles or strategic vision, but through practices of care.

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

open access: yesMathematical Finance, Volume 36, Issue 3, Page 595-619, July 2026.
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 ...

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.

Solid Mechanics Segregated Solver Acceleration With Jacobian‐Free Newton‐Krylov

open access: yesInternational Journal for Numerical Methods in Engineering, Volume 127, Issue 11, 15 June 2026.
ABSTRACT The segregated algorithm is a common approach for finite volumes solvers in solid mechanics, providing a memory‐efficient and straightforward implementation. Due to the inter‐coupling of the components through the source terms, it suffers from a slow convergence behavior in specific scenarios, such as geometries with significantly uneven ...

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.

Efficient Orbit Propagation of Orbital Elements Using Modified Chebyshev Picard Iteration Method

open access: yes, 2016
This paper focuses on propagating perturbed two-body motion using orbital elements combined with a novel integration technique. While previous studies show that Modified Chebyshev Picard Iteration (MCPI) is a powerful tool used to propagate position and ...

Integrated Transcriptomics Reveals Evolutionary Trajectories and Cell Density‐Dependent Mechanisms in Aldosterone‐Producing Adenomas

open access: yesAdvanced Science, Volume 13, Issue 32, 9 June 2026.
Aldosterone‐producing adenomas (APAs) develop via two distinct paths: directly from adrenal zona glomerulosa (zG) cells, or stepwise from zG cells through aldosterone‐producing micronodules (APMs) before progressing to APAs. Advanced single‐cell and spatial analyses identified distinct cell states linked to oxidative stress and cell–cell interactions ...
