On the Design of Turbo Codes.

, 2000
This thesis is about Turbo codes - codes constructed via parallel concatenation of two recursive convolutional encoders linked by an interleaver. The focus of the work is on the understanding and design of Turbo codes. This includes thorough investigation of central components that influence Turbo code performances, such as the constituent encoders and

Soil wetting and drying processes influence stone artefact distribution in clay‐rich soils: A case study from Middle Gidley Island in Murujuga, northwest Western Australia

Archaeometry, EarlyView.
Abstract Soils that contain swelling clay minerals (e.g., montmorillonite) expand and contract during wetting and drying, causing movement within the soil profile. This process, known as argilliturbation, can alter artefact distributions, destroy stratigraphy and complicate the interpretation of archaeological deposits.

The role of generative AI in collaborative problem‐solving of authentic challenges

British Journal of Educational Technology, EarlyView.
Abstract This study investigates undergraduate and postgraduate teamwork in a four‐week ‘Generative AI for Social Good’ hackathon, focusing on how students use GAI tools in authentic problem‐solving within their learning ecology. It examines the factors that foster productive collaboration and explores evidence of AI extending human cognition beyond ...

CRGAN-based turbo code interleaver for underwater acoustic communications

ICT Express
This paper proposes a channel response generative adversarial network (CRGAN)-based turbo code interleaver that estimates a channel response and interleaver indices at a transmitter by using a sound speed profile (SSP) and the ocean environments without ...

LLM‐based prior elicitation for Bayesian graphical modeling

British Journal of Mathematical and Statistical Psychology, EarlyView.
ABSTRACT In the Bayesian graphical modeling framework, priors on network structure encode theoretical assumptions and uncertainty about the topology of psychological constructs under study. For instance, the Bernoulli prior specifies the probability of each pairwise interaction, the Beta–Bernoulli prior governs expected network density, and the ...

Olfactory proteomics reveals the capacity of the HDAC1 inhibitor pyroxamide to halt the α‐synuclein preformed fibrils‐induced damage in nasal epithelial, microglial and dopaminergic neuronal cell lines

Brain Pathology, EarlyView.
Omics‐driven drug repositioning reveals pyroxamide as a neuroprotective HDAC1 inhibitor in Parkinson's disease models. Abstract Parkinson's disease (PD) is the second most common neurodegenerative disorder mainly characterized by the degeneration of dopaminergic neurons originating in the substantia nigra (SN) pars compacta and projecting to other ...

Iterative channel estimation and decoding algorithm for quasi-coherent demodulation of Turbo coded GMSK signals

Tongxin xuebao, 2006
A new simple iterative channel estimation algorithm for quasi-coherent demodulation Turbo coded GMSK signals was presented. Based on the iterative decoding principle of Turbo code, the algorithm improved the channel esti- mation accuracy using output of ...

sGC stimulator BAY 41‐8543 improves survival and ventricular function in a rat model of doxorubicin‐induced cardiomyopathy with nephrotic syndrome

British Journal of Pharmacology, EarlyView.
Abstract Background and Purpose Anthracyclines such as doxorubicin (DOXO) remain a cornerstone of cancer therapy but are associated with a high risk of cardiotoxicity and subsequent heart failure (HF). Impairment of NO/soluble guanylyl cyclase (sGC)/cGMP pathway has been reported in anthracycline‐induced cardiomyopathy.

Cleaning Efficacy and Surface Alterations of Titanium and Zirconia Implant Abutments Following Mechanical Instrumentation: An In Vitro Study

Clinical Oral Implants Research, EarlyView.
ABSTRACT Objectives To evaluate the cleaning efficacy, quantitative and qualitative surface modifications of titanium (Ti) and zirconia (Zr) abutments following instrumentation with twelve mechanical instrumentation modalities. Materials and Methods Twenty‐four Ti and twenty‐four Zr abutments were divided by marginal grooves into 36 test and 12 control
