Institutional change through exposing data: the James Cook University Research Portfolio

Even within a single department in an institution, research-related data exists everywhere: different formats, inconsistent databases, separate environments. In a typical situation, this data unlikely to be directly accessible, nor visible to, or perhaps even known to exist by the person or group that it pertains to. This leads to a number of problems: access, being a difficult, disjointed experience for those who seek the information; poor quality or incompleteness, as the information may be hidden and not maintained; and a potential lack of consistency across different uses of the data. Through exposing useful data from primary sources in a logical and consistent fashion, great improvements across a research institution are possible

Reversible watermarking scheme with image-independent embedding capacity

Permanent distortion is one of the main drawbacks of all the irreversible watermarking schemes. Attempts to recover the original signal after the signal passing the authentication process are being made starting just a few years ago. Some common problems, such as salt-and-pepper artefacts owing to intensity wraparound and low embedding capacity, can now be resolved. However, some significant problems remain unsolved. First, the embedding capacity is signal-dependent, i.e., capacity varies significantly depending on the nature of the host signal. The direct impact of this is compromised security for signals with low capacity. Some signals may be even non-embeddable. Secondly, while seriously tackled in irreversible watermarking schemes, the well-known problem of block-wise dependence, which opens a security gap for the vector quantisation attack and transplantation attack, are not addressed by researchers of the reversible schemes. This work proposes a reversible watermarking scheme with near-constant signal-independent embedding capacity and immunity to the vector quantisation attack and transplantation attack

The potential of combined mutation sequencing of plasma circulating cell-free DNA and matched white blood cells for treatment response prediction

Highly sensitive mutation detection methods enable the application of circulating cell-free DNA for molecular tumor profiling. Recent studies revealed that sequencing artifacts, germline variants, and clonal hematopoiesis confound the interpretation of sequencing results and complicate subsequent treatment decision making and disease monitoring. Parallel sequencing of matched white blood cells promises to overcome these issues and enables appropriate variant calling

Device and method for extracting information from characteristic signals

The present invention relates to a device and a method for extracting information from detected characteristic signals. A data stream (76, 78, 80, 82) derivable from electromagnetic radiation (14) emitted or reflected by an object (11) is received and a plurality of characteristic index elements (50) varying over time can be extracted therefrom. The index elements (50) comprise physiological information (48) indicative of at least one at least partially periodic vital signal (12), and a disturbing signal component (58). For eliminating the disturbing signal component (58) to a great extent, the characteristic index elements (50) can be projected to a disturbance-reduced index element (64) having a distinct orientation in relation to a presumed orientation of the disturbing signal component (58). The disturbance-reduced index element (64) is chosen so as to reflect a dominant main orientation and length of the disturbing signal component (58) over time. Consequently, the mainly genuine physiological information (48) extracted from the data stream (76, 78, 80, 82) in this way can be utilized for determining the at least one at least partially periodic vital signal (12)
