Mitochondrial translation and coordinated cytosolic translation in metabolic homeostasis and disease

FEBS Letters, EarlyView.
Mitochondrial function depends on coordinated protein production from the nuclear and mitochondrial genomes. This review highlights how cytosolic and mitochondrial translation, mRNA localization, protein import, and respiratory complex assembly are integrated to maintain mitochondrial proteostasis and function.

Generalized Complex Quadrature Spatial Modulation [PDF]

Wireless Communications and Mobile Computing, 2019
Spatial modulation (SM) is a multiple-input multiple-output (MIMO) system that achieves a MIMO high spectral efficiency while maintaining the transmitter computational complexity and requirements as low as those of the single-input systems. The complex quadrature spatial modulation (CQSM) builds on the QSM scheme and improves the spectral efficiency by

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

Molecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Spherical Acoustic Spatial Entropy: Predicting Acoustic Scene Complexity in Virtual Environments

IEEE Open Journal of Signal Processing
The objective quantification of Acoustic Scene Complexity (ASC) remains a significant challenge. While existing entropy-based metrics capture spectro-temporal variability, a metric accounting for the spatial distribution of sources has been lacking.

GEO-MATHEMATICAL MODELLING OF SPATIAL-ECOLOGICAL COMPLEX SYSTEMS: AN EVALUATION

Geography, Environment, Sustainability, 2010
Assessing the complexity of landscapes is one of the top research priorities for Physical Geography and Ecology. This paper aims at a methodological evaluation of the discrete and analytical mathematical models hitherto available for quantitative ...

Hijacking emergency granulopoiesis: Neutrophil ontogeny and reprogramming in cancer

Molecular Oncology, EarlyView.
Neutrophils are highly plastic innate immune cells; their functions in cancer extend beyond the tumour microenvironment. This Review summarises current understanding of neutrophil maturation and heterogeneity and highlights tumour‐induced granulopoiesis as a systemic programme that expands immature, immunosuppressive neutrophils via tumour‐derived ...

Low-Complexity Detection Algorithms for Spatial Modulation MIMO Systems

Journal of Electrical and Computer Engineering, 2018
In this paper, the authors propose three low-complexity detection schemes for spatial modulation (SM) systems based on the modified beam search (MBS) detection.

Spatial and single‐nuclei transcriptomics reveals idiosyncratic and generic patterns in papillary and anaplastic thyroid cancers

Molecular Oncology, EarlyView.
Matched spatial transcriptomics and single‐nuclei RNA‐seq were generated for anaplastic and BRAFV600E papillary thyroid cancers revealing generic and tumor‐specific states occurring in cancer cells and in the tumor microenvironment. In this context, cancer dedifferentiation mirrored organoid maturation through ordered thyroid marker gain/loss ...

Proceedings of the ECCS 2005 satellite workshop: embracing complexity in design - Paris 17 November 2005 [PDF]

, 2005
Embracing complexity in design is one of the critical issues and challenges of the 21st century. As the realization grows that design activities and artefacts display properties associated with complex adaptive systems, so grows the need to use ...
