ChemPhysChem, EarlyView.This study investigates a spin‐crossover dinuclear Fe(II) complex deposited as a thin film under ultrahigh‐vacuum conditions by a pulsed layer injection technique. Its temperature‐dependent switching behavior, light‐induced excited spin‐state trapping, soft‐X‐ray‐induced excited spin‐state trapping, and temperature‐ and light‐induced spin crossover ...

Turbo codes and turbo algorithms
Journal of Communications Software and Systems, 2006 In the first part of this paper, several basic ideas that prompted the coming of turbo codes are commented on. We then present some personal points of view on the main advances obtained in past years on turbo coding and decoding such as the circular ...

Turbo-Like Beamforming Based on Tabu Search Algorithm for Millimeter-Wave Massive MIMO Systems [PDF]
arXiv, 2015 For millimeter-wave (mmWave) massive MIMO systems, the codebook-based analog beamforming (including transmit precoding and receive combining) is usually used to compensate the severe attenuation of mmWave signals. However, conventional beamforming schemes involve complicated search among pre-defined codebooks to find out the optimal pair of analog ...

Side-Information Coding with Turbo Codes and its Application to Quantum Key Distribution
, 2004 Turbo coding is a powerful class of forward error correcting codes, which can achieve performances close to the Shannon limit. The turbo principle can be applied to the problem of side-information source coding, and we investigate here its application to

ChemPlusChem, EarlyView.This study presents a sustainable approach to functionalizing DMAP by introducing an aminomethyl group for stable anchoring on mesoporous silica supports, creating an effective, recyclable hybrid catalyst. Characterized by techniques like XRD, TGA, and FT‐IR, the hybrid retained stability and showed strong catalytic performance for the Knoevenagel ...

DeepTurbo: Deep Turbo Decoder [PDF]
arXiv, 2019 Present-day communication systems routinely use codes that approach the channel capacity when coupled with a computationally efficient decoder. However, the decoder is typically designed for the Gaussian noise channel and is known to be sub-optimal for non-Gaussian noise distribution.

Clinical Pharmacology &Therapeutics, EarlyView.The use of elexacaftor/tezacaftor/ivacaftor (ETI) has been associated with increased fertility in women with cystic fibrosis (CF) and is increasingly used during pregnancy to support both maternal and fetal health. However, little is known about the pharmacokinetics (PK) of ETI during pregnancy, which is crucial for optimizing its efficacy and safety ...

A MODIFIED UNEQUAL POWER ALLOCATION (UPA) SCHEME FOR PERFORMANCE ENHANCEMENT IN BIT REPETITION TURBO CODES IN HIGH SPEED DOWNLINK PACKET ACCESS (HSDPA) SYSTEM [PDF]
Journal of Engineering Science and Technology, 2015 In this paper, a modified optimal power allocation scheme for different bits in turbo encoder has been proposed to improve the performance of Turbo Codes system in High Speed Downlink Packet Access (HSDPA) service. In a typical turbo code in HSDPA system,

Performance Analysis of Deep Learning based on Recurrent Neural Networks for Channel Coding [PDF]
arXiv, 2018 Channel Coding has been one of the central disciplines driving the success stories of current generation LTE systems and beyond. In particular, turbo codes are mostly used for cellular and other applications where a reliable data transfer is required for latency-constrained communication in the presence of data-corrupting noise.

ChemSusChem, EarlyView.Highly controlled Pt single atom deposition (SA) is achieved by gas‐phase scattering sputtering on various substrates. This method enables soft Pt single atom loading and uniform SA distribution. In the example, it is shown that how Pt SA loading on TiO2 can be established and used for photocatalytic H2 generation.
