Notable Impact of Paleotectonic Stress on Gold Mineralisation in the West Qinling Orogen

open access: yesGeological Journal, EarlyView.
By applying fuzzy clustering and multiple inverse methods, we systematically processed the data of vein and fault slip in this ore deposit to reveal the transition of orogenic geological environment and paleotectonic stress field. Our research results show two different stress states: the northwest–southeast extensional stress field and the northeast ...

Design of prunable S-random interleavers

open access: yes, 2003
In this paper, a technique to obtain good prunable S-random interleavers to be used in parallel and serially concatenated codes with interleavers is proposed.

Iterative estimation method for random interleaver of Turbo codes

open access: yesTongxin xuebao, 2015
Channel coding parameter analysis meant reversely analyzing and estimating the coding parameters,and was one of the key techniques for intelligent communication,information interception and so on.Since Turbo codes were widely used in communication ...

A New Class of Braided Block Codes Constructed by Convolutional Interleavers

open access: yesMathematics
Parallel Concatenated Block (PCB) codes are conventionally represented as high-rate codes with low error correcting capability. To form a reliable and outstanding code, this paper presents a modification on the structure of PCB codes, which is ...

Heterogeneous Exhumation Mechanisms in Neoproterozoic Collisional Metamorphism: P–T Constraints From Pelotas and Punta del Este Terranes, Southern Brazil and Uruguay

open access: yesGeological Journal, EarlyView.
Petrography, thermobarometry, and pseudosection modelling reveal peak metamorphic conditions of 3–7.5 kbar and 520°C–800°C in Tonian‐Cryogenian orthogneisses of the Dom Feliciano Belt. Metamorphic field gradients of 27°C/km–39°C/km and variable exhumation mechanisms support correlation of these units as remnants of a Himalayan‐type Piratini Orogeny ...

Efficient Implementation of Multiple Interleavers in IDMA for 5G

open access: yes, 2018
This paper presents an efficient implementation of multiple interleavers in interleave division multiple access (IDMA) for the 5G telecommunication. Rather than focusing on designing a single interleaver efficiently, in this paper, all the interleavers ...

Multi‐omics–driven precision medicine

open access: yesiMeta, EarlyView.
Multi‐omics‐driven precision medicine (MODPM) provides a multiscale, continuously learnable framework that integrates genomics, epigenomics, transcriptomics, proteomics, metabolomics, microbiome profiles, and clinical data. Powered by artificial intelligence and foundation models, MODPM enables cross‐modal representation learning, contextual modeling ...

On the Analysis and Design of Good Algebraic Interleavers

open access: yes, 2006
This paper analyzes, classifies and searches for good coprime interleavers using the recently-developed metric of cycle correlation sum (CCS). A subset of good coprime interleavers, referred to as regular coprime interleavers, are identified and ...

On Dispersion and Nonlinearity Degree of QPP Interleavers [PDF]

open access: yes, 2012
This paper shows a link between the dispersion and the nonlinearity degree of QPP (quadratic permutation polynomial) interleavers. An upper bound for the dispersion of QPP interleavers is derived.
