Spatial and Time-Reversal Diversity Aided Least-Symbol-Error-Rate Turbo Receiver for Underwater Acoustic Communications

open access: yesIEEE Access, 2018
In this paper we propose a new type of receiver for underwater acoustic communication. The proposed receiver has the following features: 1) It has a turbo structure with an embedded adaptive decision feedback equalizer (DFE), which is based on the least ...

Assembling Nutrition‐sensitive Agriculture: How Global Food Security Projects Are Sustained Despite Tensions, Contradictions and Failure

open access: yesDevelopment and Change, Volume 56, Issue 6, Page 1167-1196, November 2025.
ABSTRACT This article examines the global discourse surrounding nutrition‐sensitive agriculture (NSA) and its implementation within Feed the Future, a food security initiative of the US Agency for International Development in Guatemala. It explores how such global nutrition efforts have increasingly incorporated critiques advanced by critical nutrition

Improving the Performance of Turbo-Coded Systems under Suzuki Fading Channels

open access: yesJournal of Low Power Electronics and Applications, 2019
In this paper, the performance of coded systems is considered in the presence of Suzuki fading channels, which is a combination of both short-fading and long-fading channels.

Advanced low‐light image transformation for accurate nighttime pavement distress detection

open access: yesComputer-Aided Civil and Infrastructure Engineering, Volume 40, Issue 28, Page 5307-5324, 28 November 2025.
Abstract Pavement distress detection is critical for road safety and infrastructure longevity. Although nighttime inspections offer advantages such as reduced traffic and enhanced operational efficiency, challenges like low visibility and noise hinder their effectiveness.

A retrotransposon insertion upstream of Arabidopsis thaliana CRK8 receptor‐like kinase modulates a trade‐off between pathogen defense and salt tolerance

open access: yesThe Plant Journal, Volume 124, Issue 4, November 2025.
Significance Statement A transposable element (TE) enhances the expression of the cysteine‐rich receptor‐like kinase gene CRK8 in Arabidopsis thaliana, thereby reducing susceptibility to the fungal pathogen Sclerotinia sclerotiorum, but reducing tolerance to salt. Considering the widespread presence/absence polymorphism of this TE in the A.

Turbo-per-Tone Equalization for ADSL Systems

open access: yesEURASIP Journal on Advances in Signal Processing, 2005
We study the equalization procedure in discrete multitone (DMT)-based systems, in particular, in DMT-based ADSL systems. Traditionally, equalization is performed in the time domain by means of a channel shortening filter.

Local Habitat Features, but Not Isolation, Shape Alpine Odonate Assemblages: Implications for Modelling and Conservation

open access: yesDiversity and Distributions, Volume 31, Issue 10, October 2025.
ABSTRACT Aim Human impacts and climate change are intensifying the fragmentation of freshwater habitats, raising concerns about the ability of aquatic species to disperse between increasingly isolated habitat patches. To explore these dynamics, we used dragonflies and damselflies (Odonata) as a model taxon to examine how two principles of island ...

Low Complexity Iterative Receiver Design for Shallow Water Acoustic Channels

open access: yesEURASIP Journal on Advances in Signal Processing, 2010
An adaptive iterative receiver structure for the shallow underwater acoustic channel (UAC) is proposed using a decision feedback equalizer (DFE) and employing bit-interleaved coded modulation with iterative decoding (BICM-ID) in conjunction with ...
