Characterizing Alzheimer's disease severity via resting-awake EEG amplitude modulation analysis.
PLoS ONE, 2013 Changes in electroencephalography (EEG) amplitude modulations have recently been linked with early-stage Alzheimer's disease (AD). Existing tools available to perform such analysis (e.g., detrended fluctuation analysis), however, provide limited gains in

New pulse modulator with low switching frequency
Tekhnologiya i Konstruirovanie v Elektronnoi Apparature, 2014 The author presents an integrating pulse modulator (analogue signal converter) with the pulse frequency and duration modulation similar to sigma-delta modulation (with low switching frequency), without quantization.

Optimal Design of Mobile Fronthaul Delta-Sigma Modulator based on Search Algorithm
Guangtongxin yanjiu, 2022 The Common Public Radio Interface (CPRI) used in mobile fronthaul has low spectrum efficiency. In this paper, we propose to use Delta-Sigma Modulation (DSM) technology as a new fronthaul interface.

Model-based predictive adaptive delta modulation
, 2007 This paper presents a new technique in digital communications that is called model-based-predictive adaptive-delta-modulation (MBP-ADM). MBP-ADM uses system identification tools to identify a model of the signal which is used for prediction.

FEBS Letters, EarlyView.In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

FEBS Letters, EarlyView.Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.
