This study presents a comparative analysis of the fractional Gross-Pitaevskii equation (GPE), a fundamental nonlinear Schrödinger-type model, focusing on the derivation of exact soliton solutions critical for understanding nonlinear phenomena such as superfluidity and superconductivity. We compare the effectiveness of β-fractional and M-truncated fractional derivatives in solving the complex fractional GPE. This comparison reveals that while both fractional derivatives enable the construction of diverse optical soliton solutions-including hyperbolic, periodic, Jacobi elliptic, and exponential forms-the β-derivative provides smoother soliton profiles with computational simplicity, whereas the M-truncated derivative captures richer oscillatory dynamics due to its enhanced memory effects. Employing advanced analytical tools-namely the generalized extended direct algebraic method (gEDAM) and the Kummar-Malik (KM) method-along with Wolfram Mathematica for verification, we extract and rigorously validate a variety of exact solutions. The generated solutions and their corresponding wave profiles under varying parameters highlight the distinct physical implications of each fractional derivative approach. Our results offer a robust framework for modeling nonlinear fractional dynamics, with applications spanning optical fibers, plasma physics, mathematical physics, and condensed matter systems. The comparative insights gained deepen the understanding of fractional-order effects in nonlinear wave evolution, paving the way for further exploration in complex physical systems.

Background: Fractional flow reserve (FFR) for non-culprit lesions (NCLs) in patients with ST-elevation myocardial infarction (STEMI) can be influenced by temporary changes in microvascular resistance. Angiography-derived vessel fractional flow reserve (vFFR) has been tested as a less-invasive alternative.
Aims: The FAST STEMI II study aimed to assess the diagnostic performance of acute-setting vFFR vs.

Background: Invasive coronary physiology including fractional flow reserve (FFR), instantaneous wave-free ratio (iFR), and coronary flow reserve (CFR) are guideline-endorsed tools to guide the management of coronary artery disease (CAD). Complex factors impact and confound these assessments, and discordance between modalities complicates clinical management. iEquate is a prospective observational trial that combines multi-modality coronary physiology and optical coherence tomography (OCT) to identify the determinants of pressure-wire derived myocardial ischemia and iFR-FFR discordance.

Introduction: Absence of language development is a condition encountered across a large range of neurodevelopmental disorders, including a significant proportion of children with autism spectrum disorder. The neurobiological underpinnings of non-verbal ASD (nvASD) remain poorly understood.
Methods: This study employed multimodal MRI to investigate white matter (WM) microstructural abnormalities in nvASD, focusing on language-related pathways.

Backgrounds: The management of non-culprit vessels (NCV) among individuals with acute myocardial infarction (AMI) remains an unsolved problem. Angiography-derived physiological assessments developed recently may help address this issue. Our study aims to measure angiography-derived fractional flow reserve (Angio-FFR) and angiography-derived index of microcirculatory resistance (Angio-IMR) in NCVs of AMI patients and explore their prognostic values and necessity.

Treatments can involve long recovery times, marked by pain, erythema, edema, and purpura, which is often a limiting factor in a patient’s willingness to undergo a procedure.
Objective: This study evaluated the safety and effectiveness of an Angiopoietin-1 derived QHREDGS peptide (Q-peptide) hydrogel and ointment, in comparison to a peptide-free control, in enhancing healing and patient satisfaction after radiofrequency microneedling (RFMN) treatment.
