Changes in Web Client Access Patterns -- Characteristics and Caching Implications
- IN WORLD WIDE WEB, SPECIAL ISSUE ON CHARACTERIZATION AND PERFORMANCE EVALUATION
"... Understanding the nature of the workloads and system demands created by users of the World Wide Web is crucial to properly designing and provisioning Web services. Previous measurements of Web client workloads have been shown to exhibit a number of characteristic features � however, it is not clear ..."

how those features may be changing with time. In this study we compare two measurements of Web client workloads separated in time by three years, both captured from the same computing facility at Boston University. The older dataset, obtained in 1995, is well-known in the research literature and has
Self-determination and persistence in a real-life setting: Toward a motivational model of high school dropout.
- Journal of Personality and Social Psychology,
, 1997
"... The purpose of this study was to propose and test a motivational model of high school dropout. The model posits that teachers, parents, and the school administration's behaviors toward students influence students' perceptions of competence and autonomy. The less autonomy supportive the so ..."

The structural organization of the septate and gap junctions of Hydra
- J. Cell
, 1972
"... The septate junctions and gap junctions of Hydra were studied utilizing the extracellular tracers lanthanum hydroxide and ruthenium red. Analysis of the septate junction from four perspectives has shown that each septum consists of a single row of hexagons sharing common sides of 50-60 A. Each hexag ..."

lying about 20 A apart. This en plaque configuration of the gap junctions of Hydra contrasts with their sparser, more widely separated distribution in many vertebrate tissues. These studies conclude that the septate junction may possess some barrier properties and that both junctions are important
Magellan Echelle Spectroscopy of TW Hydrae Brown Dwarfs
, 2003
"... We present high-resolution optical spectroscopy of four candidate members of the nearby TW Hydrae young association including three brown dwarfs (2MASS 1207-3932, 2MASS 1139-3159 and TWA 5B) and one T Tauri multiple star (TWA 5A). Using echelle spectra from the Magellan Baade 6.5-meter telescope, we ..."

Scheduling Support for Concurrency and Parallelism in the Mach Operating System
- IEEE Computer
, 1990
"... Changes in the use of multiprocessors are placing new demands on operating system schedulers. This article describes some of the new challenges posed by parallel and concurrent applications, and introduces techniques developed by the Mach project to meet these challenges. An overview of the techniqu ..."

Isolating long-term policy in a server yields the advantages of policy-mechanism separation, while avoiding the drawbacks encountered in previous applications of this principle to multiprocessor
Printed in Great Britain Studies on the transmission of hypostome inhibition in hydra
"... The inhibition of hypostome formation in hydra has been investigated using isolation and transplantation techniques. The transmission of inhibition does not seem to be polarized; a hypostome situated at the proximal end of the digestive zone can inhibit distal regeneration with no change in re-gener ..."

Party over Policy: The Dominating Impact of Group Influence
- on Political Beliefs.’’ Journal of Personality and Social Psychology
, 2003
"... Four studies demonstrated both the power of group influence in persuasion and people's blindness to it. Even under conditions of effortful processing, attitudes toward a social policy depended almost exclusively upon the stated position of one's political party. This effect overwhelmed th ..."

ssOpen AcceResearch article A fragmented metazoan organellar genome: the two mitochondrial chromosomes of Hydra magnipapillata
"... Background: Animal mitochondrial (mt) genomes are characteristically circular molecules of ~16–20 kb. Medusozoa (Cnidaria excluding Anthozoa) are exceptional in that their mt genomes are linear and sometimes subdivided into two to presumably four different molecules. In the genus Hydra, the mt genom ..."

genome comprises one or two mt chromosomes. Here, we present the whole mt genome sequence from the hydrozoan Hydra magnipapillata, comprising the first sequence of a fragmented metazoan mt genome encoded on two linear mt chromosomes (mt1 and mt2). Results: The H. magnipapillata mt chromosomes contain
NEW MEMBERS OF THE TW HYDRAE ASSOCIATION, PICTORIS MOVING GROUP, AND TUCANA/HOROLOGIUM ASSOCIATION
, 2003
"... We have identified five new members of the TW Hydrae association (TWA), 11 new members of the Pic moving group, and 11 new Tucana/Horologium association members. These are the three youngest (d30 Myr) known kinematic stellar groups near the Earth. Newly identified Pic group members are located mos ..."
