Augmented GBM Nonlinear Model to Address Spectral Variability for Hyperspectral Unmixing
Remote Sensing, 2023 Spectral unmixing (SU) is a significant preprocessing task for handling hyperspectral images (HSI), but its process is affected by nonlinearity and spectral variability (SV). Currently, SV is considered within the framework of linear mixing models (LMM),

Bilinear Fourier Multipliers of Bounded Variation
International Mathematics Research Notices, 2022 Abstract In this paper, we obtain weighted estimates for bilinear Fourier multipliers of bounded variation that provide new restricted weak-type bounds. We also study their boundedness on the setting of the weighted Lorentz spaces. The results are obtained using Rubio de Francia extrapolation as the main tool.

Hardware acceleration of number theoretic transform for zk‐SNARK
Engineering Reports, EarlyView., 2023 An FPGA‐based hardware accelerator with a multi‐level pipeline is designed to support the large‐bitwidth and large‐scale NTT tasks in zk‐SNARK. It can be flexibly scaled to different scales of FPGAs and has been equipped in the heterogeneous acceleration system with the help of HLS and OpenCL.

Unboundedness of the Ball Bilinear Multiplier Operator [PDF]
Nagoya Mathematical Journal, 2007 AbstractFor all n > 1, the characteristic function of the unit ball in ℝ2n is not the symbol of a bounded bilinear multiplier operator from Lp(ℝn) × Lq(ℝn) to Lr(ℝn) when 1/p + 1/q = 1/r and exactly one of p, q, or r′ = r/(r – 1) is less than 2.

Estimates for the commutator of bilinear Fourier multiplier [PDF]
Czechoslovak Mathematical Journal, 2013 The bilinear Fourier multipliers are a class of operators which has attracted a lot of attention of matematicians recently. Following the pioneering work of R. R. Coifman and Y. Meyer, which established boundedness of bilinear operators with very smooth symbols, a lot has been done to clarify the precise smoothness conditions on the symbol.
