Phosphor-converted white light-emitting diodes for indoor illumination need to be warm-white(i.e.,correlated color temperature,4000 K)with good color rendition(i.e.,color rendering index.80).However,no single-phosphor,single-emitting-center-converted white light-emitting diodes can simultaneously satisfy the color temperature and rendition requirements due to the lack of sufficient red spectral component in the phosphors’emission ***,we report a new yellow Ba_(0.93)Eu_(0.07)Al_(2)O_(4) phosphor that has a new orthorhombic lattice structure and exhibits a broad yellow photoluminescence band with sufficient red spectral ***-white emissions with correlated color temperature,4000 K and color rendering index.80 were readily achieved when combining the Ba_(0.93)Eu_(0.07)Al_(2)O_(4) phosphor with a blue light-emitting diode(440–470 nm).This study demonstrates that warm-white light-emitting diodes with high color rendition(i.e.,color rendering index.80)can be achieved based on single-phosphor,single-emitting-center conversion.

Individual behaviors, such as drinking, smoking, screen time, and physical activity, can be strongly influenced by the behavior of friends. At the same time, the choice of friends can be influenced by shared behavioral preferences. The actor-based stochastic models (ABsM) are developed to study the interdependence of social networks and behavior. These methods are efficient and useful for analysis of discrete behaviors, such as drinking and smoking;however, since the behavior evolution function is in an exponential format, the ABsM can generate inconsistent and unrealistic results when the behavior variable is continuous or has a large range, such as hours of television watched or body mass index. To more realistically model continuous behavior variables, we propose a co-evolution process based on a linear model which is consistent over time and has an intuitive interpretation. In the simulation study, we applied the expectation maximization (EM) and Markov chain Monte Carlo (MCMC) algorithms to find the maximum likelihood estimate (MLE) of parameter values. Additionally, we show that our assumptions are reasonable using data from the National Longitudinal study of Adolescent Health (Add Health).

spherulites of different morphological features have been obtained by varying the cooling rateof polypropylene melts through the crystallization temperature range from 120℃to 90℃. It wasfound that sALs is very sensitive to the changes of internal structure of the spherulites, and information about their morphological difference can be obtained according to the model theories and statisticaltheories of sALs.

Introduction: The use of cardiopulmonary bypass (CPB) with deep hypothermic circulatory arrest (DHCA) is an adjunctive surgical technique that can be employed for the resection of renal cell carcinoma (RCC) with venous thrombus extension superior to the level of the hepatic veins. Median sternotomy (Ms) or Minimal Access (MA) incisions may be used to establish CPB during the resection of these extensive tumors. We review our experience with both incisional approaches and compareoperative details, perioperative complications, and recurrence free survival. Materials and Methods: From 1986 to 2012, 70 radical nephrectomies with concomitant inferior vena cava (IVC) thrombectomies were performed at our institution using Ms (23 patients) and MA (47 patients) techniques. Preoperative patient characteristics, pathologic data, and organ specific postoperative complications and follow-up data were compared between groups. Estimates of overall and recurrence-free survival were constructed using Kaplan-Meier curves and compared using log-rank testing. Results: There were no significant differences with respect to patient demographics or preoperative comorbid conditions between the MA and Ms groups. The MA group showed a significant reduction (p 0.05) in the duration of postoperative mechanical ventilation, length of stay, operative time, and number of blood transfusions compared to Ms patients. Overall and organ-system specific complications demonstrated a decreased incidence of wound infection (37.9% v. 12.5%, p = 0.0135) and sepsis (14.3% v. 0%, p = 0.0137) in patients undergoing MA approach. Perioperative mortality was significantly reduced in the MA group (30.4% v. 8.5% p = 0.0179). Recurrence-free survival in the Ms group was 0.59 years and 1.2 years in the MA group (p = 0.06). Conclusions: Minimal access surgical approaches for CPB and DHCA during the resection of RCC with extensive tumor thrombus provide similar oncologic control with decreased duration of mechanical ven
