Analysis of Nonnegative Solutions for a Class of Hadamard Fractional Des with Singular Logarithmic Kernels on the Half-Line

Muthanna Journal of Pure Science
 A combined analytical/numerical research approach has been developed for solving a class of singular (nonlinear) fractional differential equations (Hadamard-type), with order ...

Multiple positive solutions for singular boundary-value problems with derivative dependence on finite and infinite intervals

Electronic Journal of Differential Equations, 2006
Summary: In this paper, Krasnoselskii's theorem and the fixed point theorem of cone expansion and compression are improved. Using the results obtained, we establish the existence of multiple positive solutions for the singular second-order boundary-value problems with derivative dependance on finite and infinite intervals.

Managing Charge Transport and Exciton Generation for Highly Efficient, Bright, and Stable Near‐Infrared Organic Radical Light‐Emitting Diodes

Advanced Functional Materials, EarlyView.
High‐performing near‐infrared (NIR) organic light‐emitting diodes are demonstrated using an efficient and stable 800 nm‐emissive organic radical and a thermally activated delayed fluorescence (TADF) host. TADF‐assisted exciton generation combined with improved charge transport enables high external quantum efficiency (>8%), high radiance (>70,000 mW sr−

Square root singularities of infinite systems of functional equations

, 2010
Infinite systems of equations appear naturally in combinatorial counting problems. Formally, we consider functional equations of the form $\mathbf{y} (x)=F(x,\mathbf{y} (x))$, where $F(x,\mathbf{y} ):\mathbb{C} \times \ell^p \to \ell^p$ is a positive and

Resolving Black Hole Singularities Using Angular Geometry: A Finite Alternative to Infinites in Spacetime Curvature

In this preprint, I introduce a new geometric model that uses only angles to describe how space bends near black holes — without any infinities, tensors, or coordinate blow-ups.At the heart of this idea is the Angular Evolution Equation (AEE), which limits curvature to a smooth maximum of 180°, allowing light and matter to turn instead of vanish.

Multidimensional‐Encoded High‐Fidelity Spectrometers With a Floating‐Base Bipolar Junction

Advanced Functional Materials, EarlyView.
A floating‐base bipolar junction photodetector enables multidimensional spectral encoding through synergistic gate‐ and drain‐bias modulation of interfacial barrier matching. The resulting complementary spectral responses form a diverse, weakly correlated response matrix, enabling robust and high‐fidelity spectral reconstruction even at sub‐nanoampere ...

The interaction of low-frequency ion-acoustic structures in relativistic degenerate plasmas: Insights from the KdV equation and the Wronskian technique

Journal of Low Frequency Noise, Vibration and Active Control
In this investigation, the nonlinear low-frequency ion-acoustic waves (IAWs) are examined in a fully relativistic, partially degenerate plasma in the presence of electron trapping in dense astrophysical environments such as white dwarfs.

Configuration‐Encoded Cell Alignment by Light‐Gated Silicon Photovoltaic Microcell Arrays

Advanced Functional Materials, EarlyView.
Light‐gated silicon photovoltaic microcells convert pulsed illumination into localized electrical cues. Arranging otherwise similar microcells into four‐lobed, six‐lobed, or circular patterns directs fibroblasts into corresponding local arrangements without wired stimulation.

NeuroVisio SyncPatch: A Skin‐Conformal Multimodal EMG–Motion Sensing Platform for Quantitative Neuromuscular Rehabilitation and Performance Monitoring

Advanced Healthcare Materials, EarlyView.
NeuroVisio SyncPatch integrates skin‐conformal electromyography (EMG) electrodes with camera‐tracked markers to jointly assess muscle activity and three‐dimensional knee kinematics during rehabilitation. Parallel feedback pathways provide real‐time kinematic guidance during movement and post‐trial neuromuscular feedback.
