Abstract Loss of ovarian hormones (i.e., menopause) leads to negative effects on metabolic health. While exercise offers significant benefits, it seems to be insufficient to completely reverse these changes. The mechanisms by which exercise conveys the effects throughout the body are still poorly understood.

A chaos MIMO transmission scheme using turbo principle for secure channel-coded transmission
Physical layer security is effective in wireless communications because it makes a transmission secure from the beginning of protocols. We have proposed a chaos multiple-input multiple-output (C-MIMO) transmission scheme that achieves both physical layer security and channel coding gain using chaos signals. C-MIMO is a type of encryption modulation and

Turbo and Turbo-Like Codes: Principles and Applications in Telecommunications
Proceedings of the IEEE, 2007For decades, the de facto standard for forward error correction was a convolutional code decoded with the Viterbi algorithm, often concatenated with another code (e.g., a Reed-Solomon code). But since the introduction of turbo codes in 1993, much more powerful codes referred to collectively as turbo and turbo-like codes have eclipsed classical methods.

Turbo equalization: principles and new results
IEEE Transactions on Communications, 2002We study the turbo equalization approach to coded data transmission over channels with intersymbol interference. In the original system invented by Douillard et al. (1995), the data are protected by a convolutional code and the receiver consists of two trellis-based detectors, one for the channel (the equalizer) and one for the code (the decoder).

The turbo principle in joint source-channel coding
Proceedings 2003 IEEE Information Theory Workshop (Cat. No.03EX674), 2004The turbo principle (iterative decoding between component decoders) is a general scheme, which we apply to joint source-channel decoding. As a realistic example (e.g., speech parameter coding), we discuss joint source-channel decoding for auto-correlated continuous-amplitude source samples. At the transmitter, the source samples are quantized and their

Softbit-source decoding based on the turbo-principle
IEEE 54th Vehicular Technology Conference. VTC Fall 2001. Proceedings (Cat. No.01CH37211), 2002This contribution deals with a robust decoding approach of source codec parameters called softbit-source decoding. It can be considered as an error concealment technique which estimates codec parameters at the receiver utilizing the residual redundancy remaining after source coding and the channel decoder reliability information.

A modified turbo principle for iterative detection and decoding
2008 IEEE International Symposium on Information Theory, 2008This paper presents a modified turbo principle (MTP) for iterative detection and decoding in multiple-antenna systems whose detector uses the max-log-MAP algorithm. The modified turbo principle intensionally introduces dependency between the messages of the max-log-MAP detector and the decoder.

A novel ARQ technique using the turbo coding principle
IEEE Communications Letters, 1997A novel automatic repeat request (ARQ) technique based on the turbo coding principle is presented. The technique uses the log-likelihood ratios generated by the decoder during a previous transmission as a priori information when decoding retransmissions. Simulation results show a significant decrease in frame error rate, especially at low-to-moderate E/
