section{introduction} the concept of {sl cartan geometry} appeared at the beginning of the twentieth century, when {e}lie cartan was working on the so-called {sl equivalence problem}, the aim of which is to determine whether two given geometric structures can be mapped bijectively onto each other by some diffeomorphism. this problem can be considered in many different contexts, such as ...
Background: The equivalent dose in the human body due to the natural gamma-emitting radionucides (238U, 232Th and 40K) in the surface soil surrounding the Consolidated Tin mine site in Bukuru-Jos, Nigeria has been determined in this study. Materials and Methods: Measurements of the soil natural radioactivity were made using a multi-channel pulseheight analyzer (Canberra Series 10 plus) coupled ...
This mass balance study investigated the metabolism and excretion of eribulin, a nontaxane microtubule dynamics inhibitor with a novel mechanism of action, in patients with advanced solid tumors. A single approximately 2 mg (approximately 80 μCi) dose of [¹⁴C]eribulin acetate was administered as a 2 to 5 min bolus injection to six patients on day 1. Blood, urine, and fecal samples were collecte...
BACKGROUND Improved cancer treatments have resulted in prolonged survival. Nevertheless, tumor symptoms and side effects still compromise physical activity and quality of life (QoL). PATIENTS AND METHODS We conducted an anonymous survey among cancer patients undergoing chemotherapy using standardized questionnaires: the 'Freiburger Fragebogen zur körperlichen Aktivität' (Freiburg Questionnair...
| A new current-mode, low-power, lowvoltage and high-speed CMOS sample-and-hold circuit has been designed and fabricated. A new currentmode di erential switching scheme has been adopted to eliminate errors caused by feedthrough injection from the sample switches. The experimental result yields 9-bit resolution in 9mW power dissipation, in a 20MHz clock frequency from a 3V power supply.
