POLYCYCLIC GROUPS, ANALYTIC GROUPS AND ALGEBRAIC GROUPS

Proceedings of the London Mathematical Society, 2002
A group \(G\) is poly-(infinite cyclic) if it has a finite subnormal series \(G=G_n\geq G_{n-1}\geq\cdots\geq G_1\geq G_0=1\) such that each quotient \(G_i/G_{i-1}\) is infinite cyclic. A basis for a poly-(infinite cyclic) group is a sequence of elements \((x_1,\dots,x_n)\) such that \(G_i=(x_1,\dots,x_i)\).

Boundary Layer Meshing and Wall Functions Selection for Numerical Simulation of Solid–Liquid Two‐Phase Flow

Energy Science &Engineering, EarlyView.
This figure illustrates the optimal near‐wall treatment schemes (first‐layer height and wall function type) for solid–liquid two‐phase CFD of suspended sediment, which are correlated with particle size and flow velocity. ABSTRACT Near‐wall treatment (boundary‐layer meshing and wall functions) is a major uncertainty in solid–liquid two‐phase CFD of ...

How (not) to Cage an Electron: The Perfluoro Cage Effect as an Extrinsic Molecular Property

Helvetica Chimica Acta, EarlyView.
A rigorous definition within Kohn–Sham density functional theory is presented for the notion of an caged electron inside perfluorinated fullerenes as radical anions. ABSTRACT The notion of a (molecular) electron cage was coined for the unique hosting capacity of perfluorocubane, suggesting the “encapsulation of an electron” within the highly symmetric ...

Effectiveness and safety of ustekinumab in pediatric Crohn's disease: Results of the REALITI study

Journal of Pediatric Gastroenterology and Nutrition, EarlyView.
Abstract Objectives Few approved treatments exist for children with Crohn's disease (CD). The REALITI study retrospectively assessed the effectiveness and safety of ustekinumab in real‐world clinical settings for children with CD. Methods Data were collected from the prospective ImproveCareNow (ICN) registry for pediatric patients (≥ 2 to <18 years old)

Precision Restoration to Minimize Soil Loss in a Watershed in the Atlantic Forest Domain

Land Degradation &Development, EarlyView.
ABSTRACT The Turvo River Watershed, located in the Zona da Mata region of Minas Gerais and part of the Doce River Basin, faces serious problems of erosion and soil degradation, which compromise and reduce the quality of local water resources. Given this scenario, it is essential to implement environmental recovery strategies that prioritize the ...

Rigorous Electromagnetic Quasinormal‐Mode Method Made Easy for Users

Laser &Photonics Reviews, EarlyView.
We present a method that combines numerical techniques with accurate approximations to enable simple and ultrafast computations of the scattered field based on quasinormal modes expansions. The method is made available in the open‐source package MANlite (https://doi.org/10.5281/zenodo.18708748), implemented within COMSOL.

Analytical and Numerical Soliton Solutions of the Shynaray II‐A Equation Using the G′G,1G$$ \left(\frac{G^{\prime }}{G},\frac{1}{G}\right) $$‐Expansion Method and Regularization‐Based Neural Networks

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT Nonlinear differential equations play a fundamental role in modeling complex physical phenomena across solid‐state physics, hydrodynamics, plasma physics, nonlinear optics, and biological systems. This study focuses on the Shynaray II‐A equation, a relatively less‐explored parametric nonlinear partial differential equation that describes ...

Optimizing Selective RF Pulses for Enhanced Signal Stability in Turbo Spin Echo Using a Differentiable Extended Phase Graph Model

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To improve slice profile consistency across echo trains in turbo spin echo (TSE) imaging, thereby reducing image blurring and increasing the accuracy of multi echo spin echo T2$$ {T}_2 $$ mapping. Methods Excitation and refocusing RF pulses were optimized for TSE using a differentiable extended phase graph model that incorporates the ...

Gap Symmetry, Electronic Structure and Interplay Between Superconductivity and Spin Density Wave in Sr1−xKxFe2As2 Superconductor

Nano Select, EarlyView.
In moderately hole‐doped Sr1−xKxFe2As2${\rm Sr}_{1-x}{\rm K}_x{\rm Fe}_2{\rm As}_2$ system the pairing state is s+−${\rm s}^{+-}$ wave pairing state mediated by spin fluctuations. As the SDW order parameter increases, TC${\rm T}_C$ decreases and TM${\rm T}_M$ increases. As temperature increases, the SDW order parameter decreases and vanishes at TM${\rm
