Chemistry – A European Journal, EarlyView.Understanding aromaticity has evolved from benzene‐centric concepts to a broad multidimensional framework spanning organic, inorganic, and excited‐state systems. This review highlights ambiguities between magnetic, electronic, geometric, and energetic descriptors, emphasizing the need for unified, multi‐criteria approaches.

Some New Characterizations and g-Minimality and Stability of g-Bases in the Hilbert Spaces
Journal of Function Spaces and Applications, 2013 The concept of g-basis in the Hilbert spaces is introduced by Guo (2012) who generalizes the Schauder basis in the Hilbert spaces. g-basis plays the similar role in g-frame theory to that the Schauder basis plays in frame theory.

Stability of Viscous Three‐Dimensional Stratified Couette Flow via Dispersion and Mixing
Communications on Pure and Applied Mathematics, EarlyView.ABSTRACT This article explores the stability of stratified Couette flow in the viscous 3d$3d$ Boussinesq equations. In this system, mixing effects arise from the shearing background, and gravity acts as a restoring force leading to dispersive internal gravity waves.

Few‐Photon Fluorescence From Ultracold Bosons in an Optical Cavity
Contributions to Plasma Physics, EarlyView.ABSTRACT Within a cavity quantum electrodynamics framework, we analyse the fluorescent spectrum of ultracold bosons in resonant and second‐harmonic generation (SHG) regimes. Two settings are considered: (i) (few) bosons in an optical lattice and (ii) a trapped two‐component dilute Bose–Einstein condensate (2BEC) within the Bogoliubov scheme.

Ergodic and fixed point theorems for sequences and nonlinear mappings in a Hilbert space
Demonstratio Mathematica, 2018 In this paper, we introduce the notion of 2-generalized hybrid sequences, extending the notion of nonexpansive and hybrid sequences introduced and studied in our previous work [Djafari Rouhani B., Ergodic theorems for nonexpansive sequences in Hilbert ...

International Journal of Eating Disorders, EarlyView.ABSTRACT Background Eating disorders characterized by recurrent binge eating are prevalent, impairing, and undertreated. Digital programme‐led interventions may increase access to recommended treatments, but completion rates are variable. Adding brief human support to digital programmes may improve completion and outcomes.

An algorithm for the split-feasibility problems with application to the split-equality problem
Journal of Inequalities and Applications, 2017 In this paper, we study the split-feasibility problem in Hilbert spaces by using the projected reflected gradient algorithm. As applications, we study the convex linear inverse problem and the split-equality problem in Hilbert spaces, and we give new ...

Epilepsia, EarlyView.Abstract Objective Detection of epilepsy‐causing structural brain lesions on magnetic resonance imaging (MRI) is critical for diagnosis, prognosis, and treatment planning in people with epilepsy. We aimed to establish an epilepsy‐directed multisite harmonized 3‐T MRI acquisition protocol for the Australian Epilepsy Project (AEP) and describe the ...
