Theory and experiment for dc and small-signal electrical modulation of an injection-locked quantum-well (QW) Fabry-Perot laser are presented. Our experiment is realized by performing side-mode injection locking of a multiple-quantum-well (MQW) InGaAsP FabryPerot (FP) laser, which has the advantage of optical wavelength conversion. We first measure the dc characteristics and optical spectra of a...

By TADAO rfAKEUCHI AND KENJI KIN0SHITA I N PREVIOUS STIJI)IES Takeuchi et al.’5 have showni that anssylophosphorylase could be demisonsstrated ins humisams amid ansimal tissue by histochemical nieanss. They did this by using the specific staimsimsg reactions of polysaccharide niewly fornssed frons glucose-i-phosphate as a result of emizynse activity. The presemsce of the enizyme was dennomistra...

Pediatric bipolar disorder (PBD) is a cyclical illness with episodes of mania and depression complicated by neurocognitive dysfunction. Mania is characterized by symptoms such as grandiosity, decreased need for sleep, flight of ideas, distractibility, increased goal-directed activity and excessive risk-taking. Low-frequency (0.01–0.1 Hz) blood oxygen level–dependent (BOLD) signals at rest have ...

ory tells us that directory structures are especially suited for information retrieval by children; however, empirical results show that they prefer keyword searching. One of the reasons for these findings could be that the directory structures and terminology are created by grown-ups. Using a card-sorting method and an enveloping system, we simulated the structure of a directory. Our goal was ...

An analysis of eight pentacoordinated (aqua) copper(II) chelates with N-alkylated amino acids revealed that they could be separated in two group s with respect to the shape of their coordination polyhedra. Group I, consisting of N,N-dimethylated derivatives, can be described as distorted square pyramids with a pseudo C4v symmetry. Group II, consisting of other N-alkylated and N,N-dialkylated de...

When mining a large database the number of patterns dis covered can easily exceed the capabilities of a human user to identify in teresting results To address this problem various techniques have been suggested to reduce and or order the patterns prior to presenting them to the user In this paper our focus is on ranking summaries generated from a single dataset where attributes can be generaliz...

Although rabbits are common domestic pets, severe respiratory allergic reactions to rabbits in households are unusual. Ory c 1, a 17-kDa glycoprotein found in saliva and fur, has previously been identified as a major rabbit allergen. In this report, we describe the cases of three patients with rabbit allergy who presented with asthma and/or rhinitis while living in households with detectable le...

A growing collection of communities worldwide is researching phenomena of human organizations using computational methods. There are pressing research issues in both the development and ongoing operations of organizations, and in organization theory and analysis, that are highly amenable to techniques for computational modeling, theory-building/testing, and experimentation. This short note is i...

Using a unifying terminology and notation an introduction to the the-ory of stratification for orbits and bundles of matrices, matrix pencilsand system pencils with applications in systems and control is presented.Canonical forms of such orbits and bundles reveal the important systemcharacteristics of the models under investigation. A stratification providesthe qualitative i...

This paper is concerned with the numerical evaluation of multi-echelon production systems. Each stage requires a fixed predetermined leadtime; furthermore, we assume a stochastic, stauonary eLd.tlmc demand process. In a previous paper, we have developed an analytical framework for determining optimal control pohclcs for such systems under an average COSt criterion The current paper Is based on ...
