锁模光纤激光器中隐形孤子脉动演化特性研究（特邀）

以锁模光纤激光器为研究平台,利用色散傅里叶变换技术,实时观察到调制频率成比例的三周期隐形孤子脉动现象。通过分析孤子的演化特性,笔者所在课题组认为孤子的调制不稳定性引起了色散波和孤子的参量耦合过程,导致了色散波和孤子的能量交换,从而产生了参量边带和隐形孤子脉动。部分能量在色散波和孤子间的交换使得孤子总能量几乎不变。因此这种孤子脉动难以通过时域脉冲序列分辨。此外,文中实验分析了隐形孤子脉动完整的演化路径,即仅通过增加泵浦功率使得脉动产生至消失的过程。与传统的可见脉动过程相比,这种隐形孤子脉动的调制周期随泵浦功率的变化较小。该工作不仅加强了对孤子脉动动力学现象的理解,还对锁模激光稳定性的提升具有重要意义。

Predicting from Early Failures the Last Failure Time of a (Log) Normal Sample

This paper presents a table of coefficients for best linear unbiased predictors (BLUPs) using the earliest r failure times to predict the n-th (last) failure time of a sample from a s-normal (or lognormal) life distribution. They are used to predict how long a sample of components will run until all fail, that is, how long a life test will last. This includes prediction of the life of a parallel system of n identical components from the first r component failure times. The table covers n = 2(1)10, r = 2(1)n - 1. The BLUPs are exact (approximate) for failure (time) censored data.

The Uncomfortable Encounter Between an Urban Black and a Rural White: The Ideological Implications of Racial Conflict on MTV's The Real World

Through MTV's The Real World, this study examines the ideological implications of reality TV that recurrently constructs racial conflict between an urban Black and a rural White. The ideological potential in the audience reading of racial conflict on The Real World seems limited because the text's ideological premise, the idea that racial problems are matters that can be resolved through interpersonal reconciliation rather than challenging racism as a system, was forcefully reinforced in the audiences' discussion about the show. However, the depiction of racial conflict on reality TV has a progressive potential in that it may make race a focal point, helping some viewers be aware of the importance of an open dialogue about different racial perspectives and experiences, which is an indispensable step toward recognizing racial problems in the broader society.     

Lambda Pi Eta: The Founding and Evolution of Communication's Undergraduate Honor Society from a Systems Perspective

From a systems standpoint, Lambda Pi Eta is an influential subsystem within the Communication discipline. The input–throughput–output teaching-learning dialectic arguably achieves maximum potential at the point where the student is positioned. The evolution of the Arkansas Alpha LPH chapter into an accredited national honor society, documented in the words of the founding student and professor, illustrate key concepts of systems thinking, sense-making, and “learning organizations.” Envisioning the student-scholar, the honor society, NCA and its institutional members, and their interconnected partners as a transformative “super-system” fosters appreciation of the active role students play in networked realms of 21st century communication and education.
