FEBS Open Bio, EarlyView.Repair of neuronal DNA damage in Alzheimer's disease by KCL‐286. (A) Amyloid‐β oligomers and plaques impair neuronal DNA repair pathways, leading to DNA double‐strand breaks and glial activation. (B) KCL‐286 activates RARβ/RXR signalling via retinoic acid response elements (RAREs), associated with increased BRCA1 expression, enhanced DNA repair and ...

On Communication Over Unknown Sparse Frequency-Selective Block-Fading Channels [PDF]
IEEE Transactions on Information Theory, 2011 This paper considers the problem of reliable communication over discrete-time channels whose impulse responses have length $L$ and exactly $S\leq L$ non-zero coefficients, and whose support and coefficients remain fixed over blocks of $N>L$ channel uses but change independently from block to block.

EURASIP Journal on Wireless Communications and Networking, 2008 Orthogonal frequency division multiplexing- (OFDM-) based amplify-and-forward (AF) cooperative communication is an effective way for single-antenna systems to exploit the spatial diversity gains in frequency-selective fading channels, but the receiver ...

On Channel Estimation for Analog Network Coding in a Frequency-Selective Fading Channel
EURASIP Journal on Wireless Communications and Networking, 2011 Recently, broadband analog network coding (ANC) was introduced for high-speed transmission over the wireless (frequency-selective fading) channel. However, ANC requires the knowledge of channel state information (CSI) for self-information removal and coherent signal detection.

Optimizing photoexcitation conditions for time‐resolved X‐ray solution scattering experiments
FEBS Open Bio, EarlyView.Time‐resolved X‐ray solution scattering (TR‐XSS) is a powerful technique to visualize how proteins change their structure in real time after light activation. Selecting the right laser photoexcitation conditions—fluence, excitation geometry, and sample refresh rate—is critical to maximize the experimental signal while avoiding unwanted side effects ...

Electrica, 2019 In the conventional multipath-decorrelating receiver, the complexity and noise enhancement increase with the number of resolvable paths. In this paper, we propose a scheme that adaptively selects a subset of the paths reducing both system complexity and ...

Performance of stack equalizer over frequency selective fading channels
2008 IEEE 16th Signal Processing, Communication and Applications Conference, 2008 In this paper, the performance of the low complexity modified stack equalizer over frequency-selective fading channels is inspected. With the help of simulation results, it is illustrated that by sacrificing the computational complexity insignificantly, the performance of the modified equalizer can be made closer to optimum.

Elevated Connectivity During Language Processing Is Associated With Cognitive Performance in SeLECTS
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Self‐Limited Epilepsy with Centrotemporal Spikes (SeLECTS) is associated with language impairments despite seizures originating in the motor cortex, suggesting aberrant cross‐network interactions. Here we tested whether functional connectivity in SeLECTS during language tasks predicts language performance.
