Magnetized CMB anisotropies

open access: yes, 2005
Possible effects of large-scale magnetic fields on the Cosmic Microwave Background (CMB) are reviewed. Depending on the specific branch of the spectrum of plasma excitations, magnetic fields are treated either within a two-fluid plasma description or ...

Magnetic Fluids. 3. Flow Characteristics of Magnetic Fluids.

open access: yesJAPANESE JOURNAL OF MULTIPHASE FLOW, 1996
流体の機能化、知能化を計る上で、混相流体の活用は重要な役割を演じるようになってきている。特に、 電磁場の作用下で高機能性を発揮する流体である磁性流体やER流体をベースとして、より高い付加価値を付けるための研究が活発化してきている。本講座では、機能流体の代表例として磁性流体を取り上げ、その基礎から応用にわたる研究の道筋を4回シリーズで解説するものである。第1回目 [1] は、混相流体的な側面から磁性流体をとらえて磁性微粒子を含む流体の特性について、次いで前回の第2回目 [2] では、磁性流体の力学を扱う場合の基礎式を中心に磁性流体力学の成り立ちについて解説した。今回は第3回目として、磁性流体のいろいろな流れの問題を取り上げ、磁場の作用下で流動特性がどのような影響を受けるか解説することにする。

Accelerated Progression of Gait Impairment in Parkinson's Disease and REM Sleep Without Atonia

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective People with Parkinson's disease (PD) and rapid eye movement (REM) sleep without atonia (RSWA) often have more severe gait disturbances compared to PD without RSWA. The association between the presence and expression of RSWA and the rate of progression of gait impairment in PD is unknown.

Experimental study of the fluidity of nanostructured magnetic fluid in a strong magnetic field

open access: yesФизико-химические аспекты изучения кластеров, наноструктур и наноматериалов
Based on magnetic fluids, new effective technical devices have been implemented, such as magnetic fluid bearings, seals, and dampers. The magnetic-viscous effect inherent to magnetic fluids can not only improve the properties of magnetic fluid units, but

Small Structures via Thermal Instability of Partially Ionized Plasma. I. Condensation Mode

open access: yes, 2007
(Shortened) Thermal instability of partially ionized plasma is investigated by linear perturbation analysis. According to the previous studies under the one fluid approach, the thermal instability is suppressed due to the magnetic pressure.

A Comprehensive Overview of the Clinical, Electrophysiological, and Neuroimaging Features of BPAN: Insights From a New Case Series

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Neurodegeneration with brain iron accumulation (NBIA) comprises a genetically and clinically heterogeneous group of rare neurological disorders characterized particularly by iron accumulation in the basal ganglia. To date, 15 genes have been associated with NBIA.

Rotating Hele-Shaw cells with ferrofluids

open access: yes, 2000
We investigate the flow of two immiscible, viscous fluids in a rotating Hele-Shaw cell, when one of the fluids is a ferrofluid and an external magnetic field is applied. The interplay between centrifugal and magnetic forces in determining the instability

Impact of APOE ε4 Genotype Load on Cognitive Function and Lipid Metabolism in Patients With Cerebral Small Vessel Disease

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Apolipoprotein ε4 (APOE ε4) is a potent genetic risk factor for Alzheimer's disease (AD). However, its role in cerebral small vessel disease (CSVD) remains unclear. Given the clinical and pathological similarities between CSVD and AD, this study aimed to investigate the associations of APOE ε4 gene dosage with cognitive function and
