Hepatitis B virus (HBV) X protein (HBx), a trans-regulator, is frequently expressed in truncated form without carboxyl-terminus in hepatocellular carcinoma (HCC), but its functional mechanisms are not fully defined. In this report, we investigated frequency of this natural HBx mutant in HCCs and its functional significance. In 102 HBV-infected patients with HCC, C-terminal truncation of HBx, in...

To model the periodicity of beats, state-of-the-art beat tracking systems use “post-processing trackers” (PPTs) that rely on several empirically determined global assumptions for tempo transition, which work well music with a steady tempo. For expressive classical music, however, these can be too rigid. With two large datasets Western piano namely Aligned Scores and Performances (ASAP) dataset ...

In this Article, the legend of Figure 1 contains a typographical error. " Two downstream effectors of NOTCH1 pathway, Hes1 & Hes5 were examined by qRT-PCR after CT-1 stimulation for 24 hrs in NIH3T3 cells (E) or 48 hrs in NPCs (F).

This study proposed a weighting function for a dynamic (DP) programming approach as the cost function to handle beat tracking. The function is utilized to adapt bandwidth of tempo deviation which reciprocal represents likelihood of relative beat position. The beat tracking surpass those scores of other algorithms for MAZ dataset, in which seven out of ten performance indexes outperforms in MIRE...

In this paper, a beat tracking system is presented that simultaneously extracts downbeats, beats, tempo and meter. After generating beat activations by a bidirectional Long Short-Term Memory recurrent neural network, the temporal structure is infered using a Hidden Markov Model (HMM). From all MIREX beat tracking evaluation results between 2006 and 2012 it obtains average results for datasets M...

In the current state-of-art beat tracker, it is common that a specific algorithm do the best on particular kind of audio. For example, the algorithm based on two-fold dynamic programing have sequential 1 st place on time-varying-tempo MAZ dataset of MIREX audio beat tracking. This study proposed a tempogram-sensing-vector (TSV) method to be adaptive to time-varying-tempo and stable-tempo excerp...
