Performance Evaluation of an Improved Multiband Impulse Radio UWB Communication System Based on Sub-Band Selection

Performance evaluation of an improved multiband impulse radio ultra-wideband (MIR UWB) system based on sub-band selection is proposed in this paper. In the improved scheme, a data mapping algorithm is introduced to a conventional MIR UWB system, and out of all the sub-bands, only partial ones are selected to transmit information data, which can improve the flexibility of sub-bands/spectrum allocation, avoid interference and provide a variety of data rates. Given diagrams of a transmitter and receiver, the exact bit error rate (BER) of the improved system is derived. A comparison of system performance between the improved MIR UWB system and the conventional MIR UWB system is presented in different channels. Simulation results show that the improved system can achieve the same data rate and better BER performance than the conventional MIR UWB system under additive white Gaussian noise (AWGN), multipath fading and interference coexistence channels. In addition, different data transmission rates and BER performances can be easily achieved by an appropriate choice of system parameters.journal articl

Forest plots of CD24 expression and the clinicopathological features of patients with gastric cancer.

<p>The squares and horizontal lines correspond to the study- specific OR and 95% CI. The area of the squares reflects the study-specific weight (inverse of the variance). The diamonds represent the pooled OR and 95% CI. The solid vertical line is at the null value (OR = 1). <b>A The relationship between CD24 expression and tumor differentiation.</b> CD24 expression was not related to tumor differentiation (OR = 0.81, 95% CI = 0.43–1.53, P = 0.52). <b>B The relationship between CD24 expression and Lauren classification.</b> CD24 expression was not different in intestinal-type and diffuse-type of gastric adenocarcinoma. (OR = 1.78, 95% CI = 0.66–4.83, P = 0.26). <b>C The relationship between CD24 expression and tumor depth.</b> CD24 expression was associated with tumor depth (OR = 0.45, 95% CI = 0.32–0.63; P<0.00001). <b>D The relationship between CD24 expression and status of lymph node.</b> CD24 expression was associated with status of lymph node (OR = 0.40, 95% CI = 0.25–0.64; P = 0.0001). <b>E The relationship between CD24 expression and TNM staging.</b> CD24 expression was associated with TNM staging of gastric cancer (OR = 0.56, 95% CI = 0.41–0.77; P = 0.0003). <i>G</i> grade; <i>T</i> tumor; <i>N</i> node.</p

Clinicopathological and Prognostic Significance of CD24 Overexpression in Patients with Gastric Cancer: A Meta-Analysis

<div><p>Objective</p><p>The prognostic significance of CD24 expression for survival in patients with gastric cancer remains controversial. We conducted a meta-analysis to investigate the impact of CD24 expression on clinicopathological features and survival outcomes in gastric cancer.</p><p>Methods</p><p>A comprehensive literature search of the electronic databases PubMed, Embase, Web of Science and China National Knowledge Infrastructure (CNKI; up to April 8, 2014) was performed for relevant studies using multiple search strategies. Correlations between CD24 expression and clinicopathological features and overall survival (OS) were analyzed.</p><p>Results</p><p>A total of 1,041 patients with gastric cancer from 9 studies were included. The pooled odds ratios (ORs) indicated CD24 expression was associated with tumor depth (OR = 0.45, 95% confidence interval [CI]  = 0.32–0.63; P<0.00001), status of lymph nodes (OR = 0.40, 95% CI = 0.25–0.64; P = 0.0001) and tumor node metastasis (TNM) stage (OR = 0.56, 95% CI = 0.41–0.77; P = 0.0003). The pooled hazard ratio (HR) for OS showed overexpression of CD24 reduced OS in gastric cancer (HR = 1.99, 95% CI = 1.29–3.07, P = 0.002). Whereas, combined ORs showed that CD24 expression had no correlation with tumor differentiation or Lauren classifications.</p><p>Conclusion</p><p>CD24 overexpression in patients with gastric cancer indicated worse survival outcomes and was associated with common clinicopathological poor prognostic factors.</p></div

Forest plot of hazard ratio for overall survival of patients with gastric cancer.

<p>The squares and horizontal lines correspond to the study- specific HR and 95% CI. The area of the squares reflects the study-specific weight (inverse of the variance). The diamonds represent the pooled HR and 95% CI. The solid vertical line is at the null value (HR = 1). The pooled HR for OS showed overexpression of CD24 reduced OS in gastric cancer (HR = 1.99, 95%CI 1.29–3.07, P = 0.002).</p

Begg's funnel plot of publication bias of hazard ratio for overall survival in the meta-analysis.

<p>The funnel plot displays log HR against its standard error (s.e.) for each individual study. The horizontal line represents the estimate of the overall HR, with the dash lines indicating the expected 95% CI for a given standard error. No evidence of publication bias was observed in the meta-analysis.</p
