Design of an Indigenised Electronic Lock‐In Amplifier [PDF]
Active and Passive Electronic Components, 2000 An indigenised lock‐in amplifier is designed that enables the accurate measurement of signals contaminated by broad‐band noise, power‐line pick‐up, frequency drift, or other sources of interference. It does this by means of an extremely narrow band detector which has the centre of its passband locked to the frequency of the signal to be measured. Large

Methods of high voltage generation by cascading amplifiers
Machinery & EnergeticsThe purpose of this study was to create a new model of a high-voltage measuring amplifier that would include several stages of operational amplifiers to increase the operating voltage range by sequentially “virtual” connecting the output voltages of each

FEBS Letters, EarlyView.Encapsulins are protein nanocompartments that play an important role in iron storage. In the Myxococcus xanthus encapsulin system, two cargo proteins called EncB and EncC contribute to iron mineralization. Here, we show that EncB and EncC generate iron‐containing minerals with distinct chemical compositions, suggesting that the composition of stored ...

Molecular Oncology, EarlyView.The novel styrylquinazolinone‐based molecule W1B effectively suppresses glioblastoma by inhibiting IGF1R and EGFR. In high‐glucose microenvironments driving tumor resistance, W1B acts synergistically with the EGFR inhibitor dacomitinib. This combination safely blocks compensatory survival signaling in zebrafish xenograft models. Showcasing promising in

From Hearing to Listening: Design and Properties of an Actively Tunable Electronic Hearing Sensor
Sensors, 2007 An important step towards understanding the working principles of the mammalian hearing sensor is the concept of an active cochlear amplifier. Theoretical arguments and physiological measurements suggest that the active cochlear amplifiers originate from

FEBS Open Bio, EarlyView.Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐
