We conducted integrative somatic-germline analyses by deeply sequencing 864 cancer-associated genes, complete genomes and transcriptomes for 300 mostly previously treated children adolescents/young adults with cancer of poor prognosis or rare tumors enrolled in the SickKids Cancer Sequencing (KiCS) program. Clinically actionable variants were identified 56% patients. Improved diagnostic accuracy led to modified management a subset. Therapeutically targetable (54% patients) unanticipated...

Many effective solutions have been proposed to reduce the redundancy of models for inference acceleration. Nevertheless, common approaches mostly focus on eliminating less important filters or constructing efficient operations, while ignoring pattern in feature maps. We reveal that many maps within a layer share similar but not identical patterns. However, it is difficult identify if features with patterns are redundant contain essential details. Therefore, instead directly removing...

Traditional economic models have rigid-form transition functions when modeling time-varying volatility of financial time series data and cannot capture other dynamics in the market. In this paper, combining Gaussian process state-space model framework stochastic (SV) model, we introduce a new regression (GPRSV) building procedures for analysis modeling. The GPRSV extends SV model. flexible nature state description allows to more We also present estimation methods demonstrate superior...

The conversion of solar energy into chemical fuels using photocatalysts has attracted a lot attention. Herein, two conjugated porous polymers (CPPs) are synthesized the Suzuki–Miyaura coupling reaction, linking 2,4,6-triphenyl-s-triazine (PTA) with either 1,10-phenanthroline [photoluminescence spectrum (PL)] or phenanthrene (PR), yielding designated as PTA–PL and PTA–PR, respectively. Incorporating pyridinic nitrogen atoms in PL is compared PR to assess its influence on photocatalytic...

Electroencephalography (EEG) reflects brain mechanisms, and existing research leverages EEG-based brain-computer interfaces for remote sensing image target detection. While most studies focus on achieving recognition, there has been less emphasis localization, which explores spatial information to enhance detection efficiency. An effective approach localization is through eye tracking. In this paper, we propose a Brain-Eye Collaboration Framework (BECF) that enables both recognition...

In this paper, we propose a novel nonparametric modeling framework for financial time series data analysis, and apply it to the problem of varying volatility modeling. Existing parametric models have rigid-form transition function they often over-fitting problems when model parameters are estimated using maximum likelihood methods. These drawbacks effect models' prediction performance. To solve problem, take Bayesian approach. By adding Gaussian process prior hidden state process, extend...

Estimating and monitoring the sleep states at home using ubiquitous infrared (IR) visual camera sensors is an essential healthcare problem. Currently, common challenge of IoT to predict stages “semantic gap” between sensory signals medical signals, where fewer correlations stage labels are observed. To bridge this gap, we propose a novel systematic methodological design (IoT-V2E) retrieve most similar EEG signal representations in database given IR query for sleep-related analysis....

It is inevitably crucial to classify sleep stage for the diagnosis of various diseases. However, existing automated methods mostly adopt "gold-standard" lectroencephalogram (EEG) or other uni-modal sensing signal PolySomnoGraphy (PSG) machine in hospital, that are expensive, importable and therefore unsuitable point-of-care monitoring at home. To enable home, this paper, we analyze relationship between infrared videos EEG propose a new task: using by distilling useful knowledge from signals...
