Stability of Cubic Functional Equation in the Spaces of Generalized Functions

Journal of Inequalities and Applications, 2007
In this paper, we reformulate and prove the Hyers-Ulam-Rassias stability theorem of the cubic functional equation f(ax+y)+f(ax−y)=af(x+y)+af(x−y)+2a(a2−1)f(x) for fixed integer a with a≠0,±1 in the spaces of Schwartz tempered

Strain and Shear Wave Elastography in Thyroid Nodules: Tissue Stiffness as a Complementary Risk Marker for Differentiating Benign, Indeterminate, and Malignant Cytology

Head &Neck, EarlyView.
ABSTRACT Objective To evaluate the diagnostic performance of shear wave elastography (SWE) and strain elastography (SE) as complementary techniques to conventional B‐mode ultrasound for differentiating benign, indeterminate, and malignant thyroid nodules. Methods This prospective cross‐sectional study included 208 thyroid nodules evaluated using B‐mode

A calculus approach to hyperfunctions III [PDF]

Nagoya Mathematical Journal, 1987
In the previous papers, [18] and [19], we have given some basis of a calculus approach to hyperfunctions. We have taken hyperfunctions with the compact support as initial values of the solutions of the heat equation. More precisely, letA′[K]be the space of analytic functionals supported by a compact subsetKofRnand letE(x, t)be then-dimensional heat ...

Diagnosis of Portal Hypertension: Advancing Towards Non‐Invasive Solutions

Portal Hypertension &Cirrhosis, EarlyView.
This review systematically summarizes a full spectrum of non‐invasive diagnostic approaches for portal hypertension (PH), including imaging modalities, elastography, serum biomarkers, composite scoring systems and endoscopic ultrasound‐guided portal pressure gradient (EUS‐PPG), and analyzes their performance across different liver disease etiologies ...

Stability in Generalized Functions

Abstract and Applied Analysis, 2011
We consider the following additive functional equation with 𝑛-independent variables: ∑𝑓(𝑛𝑖=1𝑥𝑖∑)=𝑛𝑖=1𝑓(𝑥𝑖∑)+𝑛𝑖=1𝑓(𝑥𝑖−𝑥𝑖−1) in the spaces of generalized functions.

A Linear Mathematical Model of the Vocational Training Problem in a Company Using Neutrosophic Logic, Hyperfunctions, and SuperHyperFunction [PDF]

Neutrosophic Sets and Systems
A mathematical model is a simplified representation of a practical, real-life system or a proposed idea for an executable system. Operations research methods have the ability to express the concepts of efficiency and scarcity in a well-defined ...

Pamidronic acid and cabergoline as effective long-term therapy in a 12-year-old girl with extended facial polyostotic fibrous dysplasia, prolactinoma and acromegaly in McCune-Albright syndrome: a case report

Journal of Medical Case Reports, 2012
Introduction McCune-Albright syndrome is a complex inborn disorder due to early embryonal postzygotic somatic activating mutations in the GNAS1 gene. The phenotype is very heterogeneous and includes polyostotic fibrous dysplasia, typically involving the ...

Malignancy in Pediatric Hyperfunctioning Thyroid Nodules: A Case Report and Literature Review

Clinical Endocrinology, EarlyView.
ABSTRACT Background Thyroid nodules are rare in children but carry a markedly higher risk of malignancy compared to adults (20%–26% vs. 5%). Hyperfunctioning thyroid nodules are exceptionally uncommon in the pediatric population and are typically benign.
