Instability and transition to turbulence in a free shear layer affected by a parallel magnetic field

, 2007
Instability and transition to turbulence in a temporally evolving free shear layer of an electrically conducting fluid affected by an imposed parallel magnetic field is investigated numerically. The case of low magnetic Reynolds number is considered.

[18F]Fluorodeprenyl‐D2 PET as a Tool to Monitor Disease Activity in GAD65‐Ab Autoimmune Encephalitis

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To evaluate [18F]fluorodeprenyl‐D2 ([18F]F‐DED) positron‐emission tomography (PET) imaging as a biomarker of disease activity in autoimmune encephalitis (AIE) associated with glutamic acid decarboxylase 65 (GAD65) antibodies. Methods [18F]F‐DED PET was performed in 25 GAD65‐AIE patients and 8 controls using dynamic (0–60 min) and ...

Global bifurcations to subcritical magnetorotational dynamo action in Keplerian shear flow [PDF]

, 2013
Magnetorotational dynamo action in Keplerian shear flow is a three-dimensional, non-linear magnetohydrodynamic process whose study is relevant to the understanding of accretion processes and magnetic field generation in astrophysics.

Magnetic Fluids. 2. Basic Equations of Hydrodynamics of Magnetic Fluids.

JAPANESE 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として磁性流体や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。前回 [1] はその1回目として、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解説した。今回はそれに引き続いて、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することにする。

Magnetically responsive dry fluids

Nanoscale, 2013
Ferrofluids and dry magnetic particles are two separate classes of magnetic materials with specific niche applications, mainly due to their distinct viscosity and interparticle distances. For practical applications, the stability of these two properties is highly desirable but hard to achieve.

RNA Sequencing Resolves Cryptic Pathogenic Variants in Mitochondrial Disease

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Mitochondrial diseases are the most common inherited metabolic disorders, characterized by pronounced clinical and genetic heterogeneity that complicates molecular diagnosis. Although DNA‐based sequencing approaches have become standard in genetic testing, up to half of patients remain without a definitive diagnosis.

Falling of a magnetic fluid drop in a rotating magnetic field

Наука. Инновации. Технологии, 2022
Motion of a ferrofluid drop in a liquid nonmagnetic medium under the action of a rotating magnetic field is studied experimentally. The falling drop deviation from the vertical direction is observed when it is subjected to the action of fields which ...

Choroid Plexus Enlargement and USPIO‐Based Inflammatory Feature in Cerebral Small Vessel Disease

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective The choroid plexus (CP) is a key component of the blood–cerebrospinal fluid barrier (BCSFB), but its mechanism of action in cerebral small vessel disease (CSVD) remains unclear. This study investigated CP volume (CPV) alterations and their association with conventional imaging markers in CSVD and explored the underlying role of ...

The effect of AC magnetic fields on liquid-metal free surfaces in industrialMHD.

, 2009
In this thesis we investigate free-surface instabilities which occur in various industrial processes involving liquid metal. Specifically, we examine a number of simple problems with a view to developing a plausible theoretical description based on MHD ...
