The FASEB Journal, Volume 38, Issue 20, 31 October 2024.The voltage‐gated K+ (Kv) channel KCNB1 is expressed in the hypothalamus, mainly in the arcuate nucleus, where it forms a complex with the leptin receptor. Mice lacking the KCNB1 channel (NULL) exhibit dysregulated calorie intake—a function mediated by the arcuate nucleus—along with altered leptin metabolism and signaling.

IET Radar, Sonar &Navigation, Volume 18, Issue 9, Page 1515-1530, September 2024.A novel sparse recovery space‐time adaptive processing algorithm using the more sparsity‐encouraging log‐sum penalty to approximate the ℓ0‐norm Penalty has been developed. The newly proposed algorithm shows fast convergence speed, excellent clutter suppression and target detection performance. In addition, a closed‐form analytic solution is provided in

IET Radar, Sonar &Navigation, Volume 18, Issue 9, Page 1431-1443, September 2024.A high precision estimation algorithm for ground moving targets in multi‐channel wide‐area surveillance ground moving target indication systems is proposed based on maximum likelihood method. The main concept of this novel algorithm is to estimate the azimuth angle of the detected targets using maximum likelihood method with the space steering vector ...

Journal of Computer Assisted Learning, Volume 40, Issue 4, Page 1712-1726, August 2024.Abstract Background Online interaction in blended learning is leveraged through social presence and convergence. However, little systematic work currently exists on how researchers have explored these challenges in higher education institutions and no studies have synthesised these challenges.

Three-dimensional sparse recovery space-time adaptive processing for airborne radar
The Journal of Engineering, 2019 Conventional 3-dimensional (3D) space-time adaptive processing (STAP) has achieved good performance for non-stationary clutter suppression. However, the performance of 3D STAP rapidly degrades when applied to heterogeneous clutter environment due to the ...
