MIMO Signal Multiplexing and Detection Based on Compressive Sensing and Deep Learning
IEEE Access, 2019 We propose a novel signal multiplexing and detection method for multiple-input multiple-output (MIMO) communication systems, especially when the number of transmitting and receiving antennas is limited.

α‐Synuclein aggregation landscape from phase separation to neurotoxic intermediates
FEBS Letters, EarlyView.Alpha‐synuclein aggregation in Parkinson's disease involves a complex landscape of transient intermediates, including oligomers, fibrils and liquid–liquid phase separation (LLPS). A view is emerging in which LLPS maturation into solid‐like condensates may contribute to the formation of neurotoxic species.

Loss of proton‐sensing TDAG8 increases tumor progression in mouse models of colon cancer
Molecular Oncology, EarlyView.Loss of the pH‐sensing receptor TDAG8 accelerates colorectal cancer progression in mice. Animals lacking TDAG8 expression had increased tumor growth, DNA damage, and recruitment of tumor‐associated immune cells, including macrophages, neutrophils, and monocytes.

Combining transmitter beamforming and space-time block codes in slow rayleigh flat fading channels
, 2006 196 p.In this thesis, wc consider the design of two types of closed-loop combined systems of beamforming and space-time block codes (STBC) taking the degree of the feedback channel state information (CSI) at the transmitter into account.

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‐
