Seifert surfaces in open books, and a new coding algorithm for links

We introduce a new standard form of a Seifert surface $F$. In that standard form, $F$ is obtained by successively plumbing flat annuli to a disk $D$, where the gluing regions are all in $D$. We show that any link has a Seifert surface in the standard form, and thereby present a new way of coding a link. We present an algorithm to read the code directly from a braid presentation.Comment: 10 page

Forced Convection Heat Transfer Coefficient and Pressure Drop of Diamond-Shaped Fin-Array

After reading Professor Ali Farazmand's essay "Building Administrative Capacity in the Age of Rapid Globalization: A Modest Prescription for the Twenty-First Century," one is reminded that the list of capacities we need to develop is long, the tasks are diverse, and the challenges are tremendous. By offering a "modest" prescription, Farazmand departs emphatically from recent attempts to rewrite administrative capacity by downgrading it and outsourcing it to the market or by making it imitate corporate structures and techniques. Such exercises of yesteryear are correctly being excoriated now, but it would be well to remember that this failed model was inspired and facilitated by the stagnation and many perversities of the state-centered model that it replaced. As we stand at the cusp of a new generation of public administration reforms, we are reminded by Professor Farazmand's exposition that we no longer have any widely accepted and integrative theories left to guide our practice of reform, and that a search must begin to look at past evidence with a critical eye toward developing practical and theoretical insights to advance the public administration agenda

AJTEC2011-44017 PRECISE CONTROL METHOD OF TEMPERATURE RISING SPEED OF WAFER DURING RAPID THERMAL PROCESSING WITH LAMP HEATERS

ABSTRACT In rapid thermal processing of a semiconductor wafer, temperature-rising-time is the same order of heating-time, and so keeping a given temperature-rising-speed of the wafer during the temperature-rising process is important. We made an experimental apparatus to measure the temperature-rising-speed of a ceramic ball of 2 mm in diameter heated with four halogen lamp heaters. The temperature change of the ceramic ball was measured and the heating rate of the halogen lamp heaters was controlled by a personal computer to keep a given temperature-risingspeed 50°C/s with controlling-time-interval 0.1 s. We examined the effect of various heating control methods on the error of the temperature-rising-speed of the ceramic ball. We tested the PID-control, the control with a prepared correlation, and the combined method of control with prepared correlation and PID-control. We found that the combined method is a good method to decease the error of the temperature-rising-speed. The average error of the temperature-rising-speed is 0.5°C/s and the repetition error is almost zero for the temperature-rising-speed 50°C/s during 330°C to 370°C. We also measured the effects of artificial control-delay-time and measuring-error of the monitor temperature on the error of the temperature-rising-speed

Treatment Strategy for Recurrent and Refractory Epithelial Ovarian Cancer: Efficacy of High-Dose Chemotherapy with Hematopoietic Stem Cell Transplantation

According to population statistics in Japan, approximately 3,800 women die of ovarian ­cancer annually, and approximately 6,000 are affected by this disease. Ovarian cancer is ­referred to as a “silent tumor”, since patients have few subjective symptoms and by the time symptoms are observed, the cancer has progressed to Stage III or IV in about half of the patients. The basic treatment for advanced epithelial ovarian cancer is to remove as much of the tumor as possible, and subsequently to perform anticancer therapy using drugs such as cisplatin, carboplatin and paclitaxel, all of which have been shown to be effective for epi­thelial ovarian cancer. However, the 5-year survival rate in advanced ovarian cancer patients is still only about 20%, and a treatment that leads to long-term survival has yet to be developed. Here, we review the available treatments for ovarian cancer, and present the results of high-dose chemotherapy (HDC) performed in our hospital for recurrent and refractory ­ovarian cancer
