In this paper, we investigate the welfare e ects of transition from a single-service class to two-service classes in the Internet. We consider an ISP who o ers network access to a xed user base, consisting of users who di er in their quality requirements and willingness to pay for the access. We model user-ISP interactions as a game in which the ISP makes capacity and pricing decisions to maxim...

This paper presents an optimization example using a new paradigm for viewing the work of Wireless Sensor Networks. In our earlier paper [1] the Observed Field (OF) is described as a multi-dimensional “Information Space” (ISp). The Wireless Sensor Network is described as a “Transformation Space” (TS), while the information collector is a single point consumer of information, described as an “Inf...

Idiomatic expressions (IEs) play an essential role in natural language. In this paper, we study the task of idiomatic sentence paraphrasing (ISP), which aims to paraphrase a with IE by replacing its literal paraphrase. The lack large-scale corpora idiomatic-literal parallel sentences is primary challenge for task, consider two separate solutions. First, propose unsupervised approach ISP, levera...

We report here the characterization of the catalytic component (ISP(NAR)) of a new naphthalene dioxygenase from Rhodococcus sp. strain NCIMB12038. The genes encoding the two subunits of ISP(NAR) are not homologous to their previously characterized counterparts in Pseudomonas. The deduced amino acid sequences have only 33 and 29% identity with the corresponding subunits in Pseudomonas putida NCI...

The insulin/IGF1signaling pathway (ISP) plays an essential role in long-term health. Some perturbations in this pathway are associated with diseases such as type 2 diabetes; other perturbations extend lifespan in worms, flies, and mice. The ISP regulates many biological processes, including energy storage, apoptosis, transcription, and cellular homeostasis. Such regulation involves precise rewi...

This paper studies the caching characteristics of HTTP requests and responses that pass through production Web proxies. We evaluate caching opportunities and problems. Traces with 5.9 million entries from a large Internet Service Provider (ISP) and 2.0 million entries from an Intranet firewall are studied. We find maximum cache hit rate opportunities of about 40% for an ISP and 70% for an Intra...

Kuhlthau reflects on her work in the development of the Information Search Process (ISP), a six stage model of the users’ holistic experience in the process of information seeking. The ISP model, based on two decades of empirical research, identifies three realms of experience: the affective (feelings), the cognitive (thoughts) and the physical (actions) common to each stage. Central to the ISP...

BACKGROUND Although depression has been regarded as a major public health problem, many individuals with depression still remain undetected or untreated. Despite the potential for Internet-based tools to greatly improve the success rate of screening for depression, their reliability and validity has not been well studied. Therefore the aim of this study was to evaluate the test-retest reliabili...

1. Four pelleted diets were prepared containing milk or isolated soya-bean protein (ISP) as the major protein source. The milk and ISP were given either as intact proteins or partially (0.650 hydrolyzed with papain before feeding. 2. The diets were given ad lib. to thirty-two pigs from 7-28 d of age. The pigs were slaughtered at 28 d of age. 3. Weight gains, food conversion ratios and nitrogen ...
