Magnetic Fluids. Properties of Fluid Including Magnetic Fine Particles.

open access: yesJAPANESE JOURNAL OF MULTIPHASE FLOW, 1996
技術革新を担う重要な研究課題の一つとして新素材開発とその応用面開発が挙げられる。近年材料科学の分野では、素形材料 (あるいは構造材料) に対して機能材料、さらには、知能材料の概念が広く認識されるに至り、その開発研究が進められてきている。流体材料に関してみても、水や空気、油といったいわば素形材料に相当するものに対して、電磁場の作用により機能性を発現させることのできる流体として、磁性流体やER流体の研究が進められてきている。さらに、より高度な機能性を付与したり、多機能化を進めることにより流体の知的の制御を行おうとする研究も開始されている。この意味からも混相流体は、重要な役割を演じるものと期待されている。本稿では、機能性流体の代表例として磁性流体を取り上げ ...

Upper Cervical Cord Area as a Biomarker of Conversion to Secondary Progressive Multiple Sclerosis

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective This study assessed whether upper cervical cord area (UCCA) measured on routine brain MRI can serve as a biomarker of conversion to SPMS. Methods This is a single‐center retrospective cohort study of RRMS patients with cross‐sectional and longitudinal analyses of clinical and MRI data. Future SPMS converters were matched by age, sex,

Integration of Serum Neurofilament Light Chain and Cortical Dysfunction Improves Diagnostic Accuracy in ALS

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To determine whether integration of serum neurofilament light chain (NfL) and cortical dysfunction improves diagnostic accuracy in amyotrophic lateral sclerosis (ALS) when applied alongside the Gold Coast criteria (GCC). Methods In this prospective study, 148 participants with suspected ALS were recruited (101 ALS and 47 with ALS ...

Two-dimensional numerical experiments of convection.

open access: yes, 1996
PhDI report the results of numerical studies of 2-dimensional fully compressible convection of a fluid in which the dependence of the radiative conductivity on temperature T is taken as K, (V + aT -5)1 so that central regions of the layer are unstable ...

Long‐Term Neurologic Exam Findings in People Diagnosed and Treated During Acute HIV Infection

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Evaluate clinical and laboratory correlates of abnormal neurologic exam findings after acute HIV infection (AHI). Methods Participants from the RV254/SEARCH 010 cohort in Bangkok underwent standardized neurologic examinations at Weeks 0 (AHI), 12, 96, and 288 following antiretroviral therapy (ART).
