A Constant Voltage/Current CPT System With Lightweight Characteristics for the Unmanned Aerial Vehicle

open access: yesIEEE Access
The large weight of the unmanned aerial vehicle (UAV) could cause a decrease in endurance mileage, while poor anti-offset performance could extend charging time and may even damage onboard equipment.

Effects of IGFBP4 deficiency on human preadipocyte proliferation and differentiation through the IGF1R/AKT pathway

open access: yesFEBS Open Bio, EarlyView.
IGFBP4 knockdown (KD) impairs preadipocyte proliferation and is associated with IGF1R protein downregulation and attenuated AKT phosphorylation. The mechanisms by which IGFBP4 KD influences the IGF1R/AKT signaling pathway involve newly synthesized proteins and lysosomal degradation pathways. Created in BioRender.

An Improved Wireless Battery Charging System

open access: yesEnergies, 2018
This paper presents a direct wireless battery charging system. The output current of the series-series compensated wireless power transfer (SS-WPT) system is used as a current source, and the output voltage of AC-DC converter controls the current source.

Value of MRI Outcomes for Preventive and Early‐Stage Trials in Spinocerebellar Ataxias 1 and 3

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To examine the value of MRI outcomes as endpoints for preventive and early‐stage trials of two polyglutamine spinocerebellar ataxias (SCAs). Methods A cohort of 100 participants (23 SCA1, 63 SCA3, median Scale for the Assessment and Rating of Ataxia (SARA) score = 5, 42% preataxic, and 14 gene‐negative controls) was scanned at 3T up ...

Double conditioned potential output [PDF]

open access: yes
The central point of this paper is that both - internal and external - equilibria ought to be involved in the estimation of potential output. If only the data on inflation, unemployment rate and wages are used for its evaluation, no certainty exists that
