Matrix Representations of Fuzzy Quaternion Numbers
In this paper, firstly we discuss basic arithmetic operations with fuzzy quaternion numbers. Then, we introduce anoncommutative field, formed with 2 x 2 fuzzy complex matrices which is used for the matrix representation of fuzzyquaternion numbers as ...

The Solutions of Quaternion Sylvester Equation with Arrowhead Matrix Constraints
, 2018 箭形矩阵是一类结构简单应用广泛的特殊矩阵,在四元数体上讨论Sylvester方程的箭形矩阵解及其最佳逼近问题.利用四元数矩阵的实分解和箭形矩阵的特征结构,借助Kronecker积把约束四元数矩阵方程转化为实域上无约束方程,从而得到四元数Sylvester方程AX-XB=C具有一般箭形解和自共轭箭形解的充要条件及其通解表达式.同时在相应的解集合中,获得与预先给定的四元数箭形矩阵有极小Frobenius范数的最佳逼近解.Arrowhead matrix with simple structure, is a

Investigation of some Sylvester-type quaternion matrix equations with multiple unknowns
In this paper, we consider the solvability conditions of some Sylvester-type quaternion matrix equations. We establish some practical necessary and sufficient conditions for the existence of solutions of a Sylvester-type quaternion matrix equation with ...

Mutant NPM1 in Acute Myeloid Leukemia Initiation and Maintenance
Aging and Cancer, EarlyView.NPM1 mutations drive acute myeloid leukemia by acting as neomorphic transcriptional regulators that cooperate with Menin–MLL and XPO1 to sustain HOX/MEIS1 expression and block differentiation. Targeting these mutant‐specific transcriptional dependencies provides a rational therapeutic strategy for NPM1‐mutated AML.

CX3CL1 in Early Detection of Alzheimer's Disease: Plasma Dynamics Across Age and Disease Stages
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Backgrounds Alzheimer's disease (AD) is characterized by amyloid‐beta plaques, tau tangles, and neuroinflammation. C‐X3‐C motif chemokine ligand 1 (CX3CL1, also known as fractalkine), a neuroimmune chemokine implicated in AD pathogenesis, shows inconsistent alterations in plasma/serum across studies.

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Background and Objectives Multiple sclerosis (MS) exhibits racially disparate rates of disease progression. Black people with MS (B‐PwMS) experience a more severe disease course than non‐Hispanic White people with MS (NHW‐PwMS). Here we investigated structural and functional connectivity as well as structure–function decoupling in the ...

Cracking the Code: Genotype–Phenotype Correlation Models in Sarcoglycanopathies
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Sarcoglycanopathies are among the most severe limb‐girdle muscular dystrophies (LGMD), though milder presentations have been described. These diseases are primarily caused by missense variants, but the limited predictability of their effect on protein maturation, complex formation, and transport has hindered reliable genotype ...
