Compression2: compressed sensing with compressed coil arrays [PDF]

open access: yesJournal of Cardiovascular Magnetic Resonance, 2012
Summary Compressed sensing with PCA based coil compression is a promising way to obtain high quality radial perfusion images without incurring the high computation cost and memory requirements associated with large multi-coil arrays Background Imaging with large coil arrays is desirable for rapid imaging and high signal to noise ratio.

Remote Multilinear Compressive Learning With Adaptive Compression [PDF]

open access: yesIEEE Internet of Things Journal, 2022
Multilinear Compressive Learning (MCL) is an efficient signal acquisition and learning paradigm for multidimensional signals. The level of signal compression affects the detection or classification performance of a MCL model, with higher compression rates often associated with lower inference accuracy.

Time to Compress the Time to First Compression [PDF]

open access: yesJournal of the American Heart Association, 2018
Out‐of‐hospital cardiac arrest (OHCA), often described as the most time‐sensitive and life‐threatening medical condition, remains a major public health problem.[1][1] Survival remains low in most settings, with enormous variation in community outcomes.[2][2] Although several ...

DNABIT Compress-Genome Compression Algorithm [PDF]

open access: yesBioinformation, 2011
Data compression is concerned with how information is organized in data. Efficient storage means removal of redundancy from the data being stored in the DNA molecule. Data compression algorithms remove redundancy and are used to understand biologically important molecules. We present a compression algorithm, "DNABIT Compress" for DNA sequences based on

The Complete Model of Wet Air Analysis in Mine Ventilation Design (CMWAA Method) [PDF]

open access: yesInternational Journal of Mining and Geo-Engineering
The ventilation design of mines is based on fluid dynamics. Air is the main fluid in mining ventilation. This fluid is analyzed by two models: incompressibility and compressibility.

Pushdown Compression

open access: yesCoRR, 2007
The pressing need for eficient compression schemes for XML documents has recently been focused on stack computation [6, 9], and in particular calls for a formulation of information-lossless stack or pushdown compressors that allows a formal analysis of their performance and a more ambitious use of the stack in XML compression, where so far it is mainly

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

open access: yesMolecular 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 ...
