Iterative Decoding and Turbo Equalization: The Z-Crease Phenomenon [PDF]
46th Annual Conference on Information Sciences and Systems (CISS),
Princeton, NJ, March 2012, 2013 Iterative probabilistic inference, popularly dubbed the soft-iterative paradigm, has found great use in a wide range of communication applications, including turbo decoding and turbo equalization. The classic approach of analyzing the iterative approach inevitably use the statistical and information-theoretical tools that bear ensemble-average flavors.

Turbo-Equalization Using Partial Gaussian Approximation [PDF]
IEEE Signal Processing Letters, vol. 23, No. 9, pp. 1216 -1220,
Sept. 2016, 2016 This paper deals with turbo-equalization for coded data transmission over intersymbol interference (ISI) channels. We propose a message-passing algorithm that uses the expectation-propagation rule to convert messages passed from the demodulator-decoder to the equalizer and computes messages returned by the equalizer by using a partial Gaussian ...

Prenatal Diagnosis, EarlyView.ABSTRACT Objective To explore the use of tele‐ultrasound and handheld or self‐operated ultrasound in pregnancy. Methods A systematic search provided 31 studies. The risk of bias for each study was assessed. Results were analyzed and presented in a narrative overview in four domains: tele‐ultrasound, patient‐operated ultrasound, handheld devices and low‐

Systems Engineering, EarlyView.ABSTRACT Multi‐purpose large language models (LLMs), a subset of generative artificial intelligence (AI), have recently made significant progress. While expectations for LLMs to assist systems engineering (SE) tasks are paramount; the interdisciplinary and complex nature of systems, along with the need to synthesize deep‐domain knowledge and ...

Transactions of the Institute of British Geographers, EarlyView.Abstract Disability is often overlooked in discussions of green exercise. Consequently, we still know little about how ableist ideologies might play out in the context of nature engagement, or the forms of pleasure that disabled people derive from participation in green spaces.

Magnetic Resonance in Medicine, Volume 93, Issue 5, Page 2070-2085, May 2025.Abstract Purpose The single reference variable flip angle sequence with a multi‐echo stack of stars acquisition (SR‐VFA‐SoS) simultaneously measures temperature change using proton resonance frequency (PRF) shift and T1‐based thermometry methods. This work evaluates SR‐VFA‐SoS thermometry in MR‐guided focused ultrasound in an in vivo rabbit model ...

Enhanced Mobile Multiple-Input Multiple-Output Underwater Acoustic Communications
International Journal of Distributed Sensor Networks, 2013 This paper focuses on mobile multiple-input multiple-output (MIMO) underwater acoustic communications (UAC) over double-selective channels subject to both intersymbol interference and Doppler scaling effects.

New Phytologist, Volume 246, Issue 3, Page 1147-1162, May 2025.Summary Developmental processes are known to be circadian‐regulated in plants. For instance, the circadian clock regulates genes involved in the photoperiodic flowering pathway and the initiation of leaf senescence. Furthermore, signals that entrain the circadian clock, such as energy availability, are known to vary in strength over plant development ...
