iMetaOmics, EarlyView.Chronic rhinosinusitis with nasal polyps (CRSwNP) is a heterogeneous inflammatory condition. Dysbiosis is commonly observed. This study identified distinct sinonasal microbial communities in CRSwNP patients and explored their clinical and pathological associations. Two distinct microbial communities were identified: community type 1 (CT1), dominated by

Characterizing degenerate Sturm-Liouville problems
Electronic Journal of Differential Equations, 2004 Consider the Dirichlet eigenvalue problem associated with the real two-term weighted Sturm-Liouville equation $$-(p(x)y')' = lambda r(x)y$$ on the finite interval [a,b].

Slow Body MHD Waves in Inhomogeneous Photospheric Waveguides
UniverseThe present study deals with the investigation of the oscillatory morphology of guided slow body MHD modes in inhomogeneous magnetic waveguides that appear in the solar photospheric plasmas in the forms of pores or sunspots.

New Drain Spacing Formulas Using the Variational Iteration Method
Irrigation and Drainage, EarlyView.ABSTRACT In this study, the drain spacing is computed using the variational iteration method (VIM) to the linearized Boussinesq equation. By applying at most two iterations of the VIM method under three different initial condition scenarios, three equations for drain spacing calculation were derived. These equations predict values of drain spacing that

MLEce: Statistical inference for asymptotically efficient closed-form estimators in R
SoftwareXMaximum likelihood estimation is a classical method with useful properties like efficiency, consistency, and asymptotic normality. However, the maximum likelihood estimator (MLE) cannot be in closed form in many distributions.

Arab Journal of Basic and Applied Sciences, 2019 This paper introduces new fully implicit numerical schemes for solving 1D and 2D unsteady Burgers' equation. The non-linear Burgers' equation is discretized in the spatial direction by using second order Finite difference method which converts the ...

Selfadjoint harmonic spaces and Dirichlet forms
Hiroshima Mathematical Journal, 1984 The relation between energy forms on a self-adjoint harmonic space (X,\({\mathcal H})\) studied by \textit{F. Y. Maeda} [Hiroshima Math. J. 2, 313- 337 (1972; Zbl 0273.31015), ibid. 3, 37-60 (1973; Zbl 0273.31016)] and Dirichlet forms on \(L^ 2(X,m)\) in the sense of Fukushima and Silverstein is clarified.

Journal of Quaternary Science, EarlyView.ABSTRACT Sedimentary charcoal elongation is increasingly being used in paleoecology to distinguish herbaceous from woody fuel in past fires. However, the relationship between charcoal morphotypes and plant types has never been formally tested in tropical environments, despite its potential to improve understanding of fire regimes and deforestation, and

Mapping the Influence of Ansoff's Corporate Strategy
Strategic Change, EarlyView.ABSTRACT This paper conducts a systematic, data‐driven analysis of H. Igor Ansoff's enduring impact on strategic management scholarship. Despite Ansoff's recognition as the “father of strategic management” and the continued relevance of his frameworks—including the Ansoff matrix, weak signals analysis, and strategic thrust—a comprehensive understanding

Strategic Change, EarlyView.ABSTRACT This systematic review examines how H. Igor Ansoff's theoretical contributions have evolved in contemporary strategic management through cluster analysis of 116 publications (1968–2024). Four distinct research clusters were identified, revealing that Ansoff's legacy has shifted from theoretical foundations to pedagogical applications and ...
