Use of the Response Function in the Analysis of Complex Neutron Spectra
Neutron time-of-flight spectra with overlap** peaks must be unfolded to yield contributions of individual neutron groups. This requires an accurate knowledge of the resolution profile of each group. It is al...

Recent Results of Neutron Inelastic Scattering to Higher-Excited Levels in 232Th and 238U
Neutron inelastic scattering cross sections for levels of 232Th and 238U between 680 and 1200 keV excitation energy have been measured in the neutron energy range 0.9–1.5 MeV. Nearly monoenergetic neutrons were g...

A New Technique: Insertive Esophagogastrostomy
Anastomotic leakage, stricture, and reflux esophagitis are quite commonly encountered after resection and reconstruction for esophageal carcinoma. These complications may delay convalescence and even be life t...

Interfacial Waves in Hele-Shaw Cells of Liquid Crystal-Air Systems
When a liquid is pushed by a less viscous fluid (e.g. air) in a thin linear cell, instability of the interface develops and a viscous finger is formed. This problem was first studied by SAFFMAN and TAYLOR [1] ...

Reliability Concept Applied to Optimum Configuration of Fibrous Composites
The strength and stiffness of composite materials change remarkably by changing the kinds, volume contents, and orientations of the reinforcing fibers and stacking sequences. Therefore optimum material design ...

Maximum Spacing Estimates: A Generalization and Improvement on Maximum Likelihood Estimates I
Hoffmann-Jorgensen (1992) presents a fairly general framework for considering consistency and asymptotic normality of “M-estimates.” The most celebrated such estimate is the famous maximum likelihood estimate ...
