If the LDPC-staircase performances were also improved, they were not as close to an ideal code as the LDPC-triangle codes were. The first goal of this work is to reduce the gap between the LDPC-staircase codes and the theoretical limit. We show that a simple modification of the parity ...
After the success of using this approach to capture butterfly flight, Johansson is interested in seeing how it applies more generally to model flight in other creatures, ranging from birds and bats down to microscopic organisms. Nature has been perfecting flight much longer than any human. By st...
Also, the quantization vectors represent quantization of results of pitch filtering of sound segment data. Thus, an inverse pitch filter is applied to the identified strings of quantization vectors in the module of generating the speech data sequence. 展开 ...
Humans and animals are not always rational. They not only rationally exploit rewards but also explore an environment owing to their curiosity. However, the mechanism of such curiosity-driven irrational behavior is largely unknown. Here, we developed a de
Extracting meaning from a dynamic and variable flow of incoming information is a major goal of both natural and artificial intelligence. Computer vision (CV) guided by deep learning (DL) has made significant strides in recognizing a specific identity des
A new method of phylogenetic reconstruction based on gene presence and absence, called conditioned reconstruction, has improved our prospects for reconstructing prokaryotic evolution. It is also able to detect past genome fusions, such as the fusion that appears to have created the first eukaryote. ...
Also, unconsumed logs increase the risk of transaction ID wraparound. Both situations can cause the server to become unavailable. Therefore, it is critical that logical replication slots are consumed continuously. If a logical replication slot is no longer used, drop it immediately....
A simple technique is also proposed to make the sphere decoding complexity less sensitive to the initial search radius. These approaches are also shown to provide significant reductions in the complexity of list sphere decoders, which can be deployed as soft-output MIMO decoders. 展开 ...
we found a dependency of the pupil size on the horizontal gaze angle. This dependency is most likely a result of the so-called pupil foreshortening error (PFE). PFE is mainly influenced by the apparent change in the shape of the pupil when moving away from a camera, which is a well-kno...
Hypertension, characterised by a constant high blood pressure, is the primary risk factor for multiple cardiovascular events and a major cause of death in adults. Excitingly, innovations in high-throughput technologies have enabled the global exploration
