PhysioNet/CinC Challenge 2015|
15 February, 2015 12:00:00 AM EST
The PhysioNet/Computing in Cardiology Challenge 2015 is now open.
This year's challenge is 'Reducing False Arrhythmia Alarms in the
ICU'. False alarms in the ICU can lead to a disruption of care,
impacting both the patient and the clinical staff through noise
disturbances, desensitization to warnings and slowing of response
times, leading to decreased quality of care. To address this issue,
competitors are challenged to devise a method of processing all the
available data to reduce false alarms with minimal or no effect on
true (vital) alarms.
New software packages added to PhysioToolkit!
31 January, 2015 12:00:00 PM EDT
Two new software packages have been added to PhysioToolkit! The first package, D3Maps, is a tool for visualizing the behavior of complex systems by means of the dynamical density delay mapping technique. This package was developed at the Wyss Institute by A. Burykin, L. Citi, M.D. Costa and A.L. Goldberger. The second software package, Multiscale Multifractal Analysis, is a time series analysis method designed to describe scaling properties of fluctuations within a signal. The software package was contributed by Jan Gierałtowski from Warsaw University of Technology.
PhysioNet approved as repository
for Nature's Scientific Data!
23 January 2015 12:00:00 AM EDT
PhysioNet is pleased to announce that we are now an officially recommended repository for the journal Scientific Data (SciData). SciData is an open-access, peer-reviewed publication from the Nature Publishing Group focusing on scientifically valuable research datasets. SciData's primary article-type, the Data Descriptor, is designed to make your data more discoverable, interpretable and reusable. Users who have contributed data to PhysioNet are now invited to submit their unpublished data as a Data Descriptor to Scientific Data! Pre-submission enquires are welcome at firstname.lastname@example.org.
New Database Added: CEBSDB
12 December 2014 12:00:00 AM EDT
Combined measurement of ECG, Breathing, and Seismocardiograms DataBase ( CEBSDB).
A dataset of 60 records from 20 volunteers has been contributed to PhysioBank by Miguel Angel Garcia Gonzalez and Ariadna Argelagos Palou from the Universitat Politecnica de Catalunya. Each record contains two ECGs, a respiration, and a seismocardiogram signals. The database was designed to check if errors in RR series are influenced by breathing, and if there is a significant variability in RR series estimated from ECGs versus seismocardiograms.
New Softwares added to PhysioToolkit
4 November 2014 9:00:00 EDT
Two new software packages have been added to the PhysioTookit library.
FECGSyn is a new Foetal ECG Waveform Generator
contributed by Joachim Behar and Gari Clifford's group at University of Oxford. The second package, the
Random Search Toolbox, is a MATLAB toolbox for selecting
model hyper-parameters via random search, also contributed by Joachim Behar and Gari Clifford's group.
Computing Cardiology 2014/Critical Data Marathon
30 July 2014 10:00:00 EDT
Two upcoming events this September at MIT will be of interest to PhysioNet users. The first is the International Critical Care Data Mining Marathon, a weekend event ( 5-7 September 2014). The International Critical Care Data Mining Marathon will bring together teams of engineers and clinicians to develop tools and crowd-source knowledge in clinical data, with a hands-on data mining workshop using the MIMIC II Database. The second event is the 2014 Computing in Cardiology conference held from September 7-10, 2014 at Cambridge, Massachusetts. Computing in Cardiology is an international scientific conference that has been held annually since 1974 and hosting PhysioNet Challenges since 2000. This conference provides a forum for scientists and professionals from the fields of medicine, physics, engineering and computer science to discuss their current research in topics pertaining to computing in clinical cardiology and cardiovascular physiology.
