TWO‐POINT BOUNDARY VALUE PROBLEMS AT RESONANCE

open access: yesMathematical Modelling and Analysis, 2009
Consider two‐point boundary value problems of resonance type x″ +x = f(t, x, x′), x(0) = x(π) = 0. We investigate existence and multiplicity of solutions to such problems by using the quasilinearization process.

The therapeutic opportunities and pitfalls of using iron ion chelators to treat neurodegenerative diseases

open access: yesFEBS Letters, EarlyView.
Although too much iron in the brain promotes neurodegeneration, iron ion chelators have had mixed effects in clinical trials. This review explains why; some chelators do not render the iron redox‐inactive (e.g., L1) whereas others do (e.g., desferrioxamine).

Existence of positive solutions for multi-point resonance systems of differential equations with boundary value conditions

open access: yesJournal of Hebei University of Science and Technology, 2016
It is difficult to study the existence of solutions for boundary value problems of differential equations at resonance, moreover, to get positive solutions of boundary value problems for differential equations at resonance is more difficult.

On the solvability of a two point boundary value problem at resonance II

open access: yesTopological Methods in Nonlinear Analysis, 1993
For part I see [the authors, ibid. 1, No. 2, 295-302 (1993; Zbl 0787.34022)]. The authors study the boundary value problem \[ u''+ k^2u+g(x,u)=h(x), \quad u(0)= u(\pi)=0, \] where \(k\geq 1\) is an integer, the Carathéodory function \(g\) for almost all \(x\) satisfies the growth restriction \(\limsup_{| u|\to \infty}| g(x,u)/u |\leq \Gamma(x)\) with \(

Single‐molecule DNA flow‐stretch assays for high‐throughput DNA–protein interaction studies

open access: yesFEBS Open Bio, EarlyView.
We describe an optimised single‐molecule DNA flow‐stretch assay that visualises DNA–protein interactions in real time. Linear DNA fragments are tethered to a surface and stretched by buffer flow for fluorescence imaging. Using λ and φX174 DNA, this protocol enhances reproducibility and accessibility, providing a versatile approach for studying diverse ...

Positive solutions of two-point boundary value problems of nonlinear fractional differential equation at resonance

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2011
This paper is concerned with a kind of nonlinear fractional differential boundary value problem at resonance with Caputo's fractional derivative. Our main approach is the recent Leggett-Williams norm-type theorem for coincidences due to O'Regan and Zima.

Self‐Regulated Learning Meets AI: Reinterpreting Self‐Regulation, Co‐Regulation, and Socially Shared Regulation in Human–AI Interaction

open access: yesNew Directions for Adult and Continuing Education, EarlyView.
ABSTRACT Advancing artificial intelligence (AI) has transformed learning and work, yet higher education and professional development programs have not systematically equipped learners for AI‐prevalent environments. This lack of preparation creates uncertainty regarding control, responsibility, trust, and accountability.

FDG‐PET Associations With Disease Severity and Outcomes in NMDA‐Receptor IgG Autoimmune Encephalitis

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Patients with N‐methyl‐D‐aspartate (NMDA) receptor‐immunoglobulin G (IgG) autoimmune encephalitis (NMDAR‐IgG AE) demonstrate occipital lobe hypometabolism on baseline brain fluorodeoxyglucose‐positron emission tomography (bFDG‐PET).
