RESTORING THE SIGNAL BY MODULES OF MEASUREMENT
Vestnik of Samara University. Natural Science Series, 2016 The questions of the selection of vectors in finite-dimensional real and complex spaces so that the modules of scalar products of these vectors with the unknown vector were possible to restore it, are observed. Also, the injectivity of nonlinear mappings is studied.

EXIT-chart aided near-capacity irregular bit-interleaved coded modulation design [PDF]
, 2009 A near-capacity irregular Bit-Interleaved Coded Modulation based Iterative Decoding (Ir-BICM-ID) aided scheme is proposed. The irregular design of the scheme pervades the three basic components of BICM-ID, namely the encoder, the unity-rate precoder and ...

FEBS Letters, EarlyView.Structural and biochemical characterisations show that the planar cell polarity (PCP) protein Inturned harbours a unique PDZ‐like domain that does not bind canonical PDZ‐binding motifs (PBMs) like that of another PCP protein Vangl2. In contrast, the apical‐basal polarity protein Scribble contains four PDZ domains that bind Vangl2, but one PDZ domain ...

Bit-Interleaved Sphere-Packing-Aided Iteratively Detected Space-Time Coded Modulation [PDF]
, 2009 We design a bit-interleaved space-time coded modulation scheme using iterative decoding (BI-STCM-ID) combined with a new multidimensional mapping scheme invoking sphere-packing (SP) modulation, which we refer to as the space-time block-coded sphere ...

Spatial modulation of fast antenna switch
Dianzi Jishu Yingyong, 2018 A fast switching spatial modulation scheme is proposed to improve the secrecy performance of the spatial modulation signal. The signal is a space-spread-spectrum signal associated with the channel information because of fast antenna switch.

Calpain small subunit homodimerization is robust and calcium‐independent
FEBS Letters, EarlyView.Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties
FEBS Letters, EarlyView.A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Turbo Detection of Precoded Sphere Packing Modulation Using Four Transmit Antennas for Differential Space-Time Spreading [PDF]
, 2008 This paper presents a novel turbo-detected multidimensional Sphere Packing (SP) modulation scheme using four transmit antennas combined with Differentially encoded Space-Time Spreading (DSTS). The DSTS scheme can be readily combined with PSK, QAM as well
