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.

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 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 Users who have contributed data to PhysioNet are now invited to submit their unpublished data as a Data Descriptor to Scientific Data!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:
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.

Two new software packages have been added to the PhysioTookit library.
FECGSyn is a new Foetal ECG Waveform Generator contributed by Joachim Behar and colleagues in Gari Clifford's group at the 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 colleagues in Gari Clifford's group.

PhysioNet users with an interest in sleep physiology now have access to the web
site of the National Sleep
Research Resource (NSRR), which hosts large annotated collections of EDF
polysomnograms and related clinical data elements from well-characterized
research cohorts and clinical trials. The first data set available includes
over 8,000 studies from exams 1 and 2 of the Sleep Heart Health Study, with
scheduled new data releases every quarter from additional data sets. NSRR also
provides open-source software for viewing and analyzing these data.

The ECG-ID Database is a set of 310
ECGs from 90 volunteers, created and contributed to PhysioBank by Tatiana
Lugovaya, who used the data in her master's thesis on the topic of biometric
human identification using the ECG. An
excellent summary of this
thesis, with a discussion of the challenges in using ECGs as biometrics,
and a comparison of the author's methods and results with those of three
previous studies, is also available.

A set of high-resolution multichannel
EEG recordings — created and contributed by Luca Citi, Riccardo
Poli, and Caterina Cinel — was generated as part of a study aimed at
identifying the factors limiting the performance of brain-computer interfaces
(BCIs) based on event-related potentials (ERPs), in order to improve the
transfer rate and the usability of these interfaces. Twenty recordings of each
of 10 participants include annotated 64-channel EEGs and 4-channel EOGs,
generated while the participants focused on specified target characters
displayed by a traditional matrix speller.

A collection of motion artifact
contaminated fNIRS and EEG data has been contributed to PhysioBank by Kevin
Sweeney and colleagues at the National University of Ireland in Maynooth. The
data set contains examples of functional near-infrared spectroscopy (fNIRS) and
electroencephalogram (EEG) recordings that have been created for evaluating
artifact removal methods. In each such recording, one or two pairs of similar
physiological signals have been acquired from transducers in close proximity.
One signal of each pair is contaminated by motion artifact, documented in each
case by simultaneously recorded outputs of 3-axis accelerometers affixed to

The CTU-UHB Intrapartum
Cardiotocography Database, from the Czech Technical University (CTU) in
Prague and the University Hospital in Brno (UHB), contains 552 cardiotocography
(CTG) recordings, which were carefully selected from 9164 recordings collected
between 2010 and 2012 at UHB. The CTG recordings start no more than 90 minutes
before actual delivery, and each is at most 90 minutes long. Each CTG contains
a fetal heart rate (FHR) time series and a uterine contraction (UC) signal,
each sampled at 4 Hz. Each CTG is accompanied by maternal, delivery, and fetal

A contribution of simulated fetal
phonocardiograms is now available in PhysioBank. The synthetic PCGs
exhibit a realistic range of signal-to-noise ratios, with simulated maternal
heart and organ sounds, fetal movements, and environmental sounds.

The 15th annual PhysioNet/CinC Challenge, Robust
Detection of Heart Beats in Multimodal Data, is now underway.
