Purpose The feasibility of reduced-port laparoscopic surgery (RPS) in colon cancer remains uncertain. This study aimed to compare the short-term outcomes of RPS and multiport surgery (MPS) in colon cancer using propensity score matching analysis. Methods A total of 302 patients with colon cancer who underwent laparoscopic anterior resection (AR) (n = 184) or right hemicolectomy (RHC) (n = 118...

Rhizoma Paridis Saponins (RPS), a natural compound purified from Rhizoma Paridis, has been found to inhibit cancer growth in vitro and in animal models of cancer. However, its effects on esophageal cancer remain unexplored. The purpose of this study was to investigate the effects of RPS on tumor growth in a rat model of esophageal cancer and the molecular mechanism underlying the effects. A rat...

Time series analysis is a statistical analysis of sequences of data, where temporal correlations are to be characterized and interpreted. Depending on the hypothesis about the source of such correlations, different techniques can be employed. In this talk we focus on the reconstruction of vector valued auxillary spaces from the observed data, which serve as a state space for the dynamics of the...

In this paper, we present an approach for image reconstruction from local phase vectors in the monogenic scale space. The local phase vector contains not only the local phase but also the local orientation of the original signal, which enables the simultaneous estimation of the structural and geometric information. Consequently, the local phase vector preserves a lot of important information of...

Background/introduction MR temperature mapping based on the proton resonance frequency (PRF) shift is used in MR-guided focused ultrasound procedures for dosimetry and safety monitoring. While conventional PRF-shift thermometry is based on calculating a phase difference between two reconstructed MR images, Gaur et al [1,2] have recently described two algorithms that estimate temperatureinduced ...

Phase space reconstruction is investigated as a diagnostic tool for determining the structure of detected nonlinear processes in regression residuals. Empirical evidence supporting this approach is provided using simulations from an Ikeda mapping and the S&P 500. Results in the form of phase portraits (e.g., scatter plots of reconstructed dynamical systems) provide qualitative information to di...

The paper introduced a new method based on probability density function (PDF) and phase space diagram method for photoplethysmography (PPG) signal extracting. In the paper, PPG information was generated from human fingertips by smartphones. The pulse wave period was then separated and reconstructed into probability density function (PDF) by the phase space diagram algorithm. The difference betw...

The importance of phase information in the perceptual quality of the speech signals is studied in this paper. Many speech synthesisers do not use the original phase information of the signals assuming their contribution is almost inaudible. The Relative Phase Shift (RPS) representation of the phase allows straightforward phase structure analysis, manipulation and resynthesis, and we use these f...
