Nanoparticle‐Mediated Immunometabolic‐Epigenetic Remodeling Enhances Schwann Cell‐Macrophage Interaction for Sciatic Nerve Regeneration

open access: yesAdvanced Science, EarlyView.
A biomimetic Prussian White nanoparticle (PW) is engineered to achieve long‐term local retention and orchestrate immunometabolic‐epigenetic remodeling for sciatic nerve regeneration. PW directly targets hexokinase 2 to suppress glycolysis, thereby elevating α‐ketoglutarate and driving Kdm4a/b‐mediated demethylation of H3K9me3.

Shunt Active Power Filter with Dynamic Output Current Limitation [PDF]

open access: yes2007 IEEE International Symposium on Industrial Electronics, 2007
This paper presents a shunt active filter with a controller able to dynamically limit the output current, which allows an effective protection of the inverter semiconductors without diminishing the active filter performance. The control strategy is based on the p-q theory expanded for three-phase four-wire systems and the power stage of the active ...

Nernstian Diagnostics of Imperfect Selectivity in Naphthalene Diimide‐Based Aqueous Organic Redox Flow Battery

open access: yesAdvanced Science, EarlyView.
Non‐ideal redox electrolytes still govern the Nernstian behavior of electrode potentials in aqueous organic redox flow batteries under operation. We utilized this effect to analytically predict two scenarios of battery performance degradation. ABSTRACT Aqueous organic redox flow batteries (AORFBs) enhance the sustainability of battery energy storage ...

A plug-and-play ripple mitigation approach for DC-links in hybrid systems [PDF]

open access: yes, 2016
© 2016 IEEE.In this paper, a plug-and-play ripple mitigation technique is proposed. It requires only the sensing of the DC-link voltage and can operate fully independently to remove the low-frequency voltage ripple. The proposed technique is nonintrusive

Osteological correlates of the respiratory and vascular systems in the neural canals of Mesozoic ornithurines Ichthyornis and Janavis

open access: yesThe Anatomical Record, EarlyView.
Abstract In birds, the neural canal houses a variety of anatomical structures including the spinal cord, meninges, spinal vasculature, and respiratory diverticula. Among these, paramedullary diverticula and the extradural dorsal spinal vein may leave behind osteological correlates in the form of pneumatic foramina and fossae, and a bilobed geometry of ...

Effect of Line Impedance on the Stability of Shunt Active Power Filter Based on LCL Filter

open access: yesKongzhi Yu Xinxi Jishu, 2018
When shunt active power filter based on LCL filter is used for voltage source type harmonic source, the line and load impedances will not only cause the harmonic amplification but also the stability problem based on current tracking.
