Rational Tuning of Hygroscopic Oscillation of Stacked Nanoflake Assemblies for Continuous Ambient Energy Harvesting

open access: yesAdvanced Materials, EarlyView.
Stacked nanoflake assembly (SNA) membranes can oscillate autonomously, offering opportunities for soft actuation and energy harvesting. This work uncovers the physical mechanism behind the sustained oscillation of SNA membranes in gradient humidity and identifies three governing dimensionless parameters, enabling rational design for optimizing SNA ...

Pathophysiology, diagnosis and treatment of tachycardiomyopathy. [PDF]

open access: yes, 2017
Tachycardiomyopathies (TCMP) are an important cause of left ventricular (LV) dysfunction that should be recognised by physicians as they are potentially reversible and have a significant impact on morbidity and prognosis.

Magnetic Textiles: A Review of Materials, Fabrication, Properties, and Applications

open access: yesAdvanced Materials Technologies, EarlyView.
Magnetic textiles (M‐textiles) are emerging as a programmable materials platform that merges magnetic matter with hierarchical textile structures. This article consolidates magnetic material classes, textile architectures, and fabrication and magnetization strategies, revealing structure–property–function relationships that govern magneto‐mechanical ...

CLINICAL USE OF HIS BUNDLE PACING

open access: yesNihon Naika Gakkai Zasshi, 1976
His束心電図記録に際して重要なことは, His東電位(H)のvalidationである.とくにHis-Purkinje系の伝導時間(HV)の定量的測定にはHのvalidationが必須である. Hのvalidationの方法としてHis束ペーシングが有用である. HとRB (右脚電位)の鑑別, His束内プロック時のH′(distal H)とRBの鑑別にはHis束ペーシングが有力である.われわれは左軸偏位を伴う右脚ブロック(RBBB+LAD)4例,房室ブロック6例, His束内ブロック1例, Wolff-Parkinson-White (WPW)症候群8例を含む30例でHis束心電図記録と同時にHis束ペーシングを行ない,その有用性を確認した.正常者群ではHis束ペーシング中 ...

Osborn Waves: History and Significance [PDF]

open access: yes, 2004
The Osborn wave is a deflection with a dome or hump configuration occurring at the R-ST junction (J point) on the ECG (Fig. 1). In the historical view, different names have been used for this wave in the medical literature, such as “camel-hump sign ...
