Utility of red‐light ultrafast optogenetic stimulation of the auditory pathway

open access: yesEMBO Molecular Medicine, 2021
Optogenetic stimulation of spiral ganglion neurons (SGNs) in the ear provides a future alternative to electrical stimulation used in current cochlear implants. Here, we employed fast and very fast variants of the red‐light‐activated channelrhodopsin (ChR)

Dynamic-range estimation [PDF]

open access: yesIEEE Transactions on Computer-Aided Design of Integrated Circuits and Systems, 2006
It has been widely recognized that the dynamic-range information of an application can be exploited to reduce the datapath bitwidth of either processors or application-specific integrated circuits and, therefore, the overall circuit area, delay, and power consumption.

A Comparative Study of Cerebral Oxygenation During Exercise in Hemodialysis and Peritoneal Dialysis Patients

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Cognitive impairment and exercise intolerance are common in dialysis patients. Cerebral perfusion and oxygenation play a major role in both cognitive function and exercise execution; HD session per se aggravates cerebral ischemia in this population. This study aimed to compare cerebral oxygenation and perfusion at rest and in mild

Design of a high-precision ADC for the application of monitoring electric power in power grid

open access: yesDianzi Jishu Yingyong, 2018
In order to meet the needs of electric power system monitoring, a 3 bit 5 order sigma-delta ADC is designed and implemented. The measurement results show that the dynamic range of the system is higher than 100 dB and the effective bit is greater than 16 ...

High‐dynamic range image generation from single low‐dynamic range image

open access: yesIET Image Processing, 2016
Due to the growing popularity of high‐dynamic range (HDR) image and the high complexity to capture HDR image, researchers focus on converting low‐dynamic range (LDR) content to HDR, which gives rise to a number of dynamic range expansion methods. Most of the existing methods try their best to tackle highlight areas during the expanding, however, in ...

Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM

open access: yesFEBS Letters, EarlyView.
Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.

An Approach for a Wide Dynamic Range Low-Noise Current Readout Circuit

open access: yesJournal of Low Power Electronics and Applications, 2020
Designing low-noise current readout circuits at high speed is challenging. There is a need for preamplification stages to amplify weak input currents before being processed by conventional integrator based readout.

Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

open access: yesFEBS Letters, EarlyView.
Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...
