SAS® ODS provides programmers with the ability to extract selected information from a procedure and store it in datasets. Such datasets can then be combined to summarize the results from numerous procedures. The SAS Macro facility can be used to execute and extract information from repetitively called SAS procedures. “Macro Variable Arrays” can simplify the extraction of information from SAS pr...

This work introduces a new unsupervised approach to multilingual word sense disambiguation. Its main purpose is to automatically choose the intended sense (meaning) of a word in a particular context for different languages. It does so by selecting the correct Babel synset for the word and the various Wiki Page titles that mention the word. BabelNet contains all the output information that our s...

The goal of this work is to make it practical to compute corpus-based statistics for all substrings (ngrams). Anything you can do with words, we ought to be able to do with substrings. This paper will show how to compute many statistics of interest for all substrings (ngrams) in a large corpus. The method not only computes standard corpus frequency, freq, and document frequency, df , but genera...

The freq uency of plantar ulcer is such that, i n many places, new cases occur more rapidly than med ical care can heal and prevent the recurrence of exist ing ones. A method of prevent ion is essent ial if progress is to be made . . There are several possible approaches to the problem, and their study needs to be correlated with the subseq uent ulcer-history of the foot. They can be undertaken...

This paper covers new optical packet switching router technologies, system architectures, and the future photonic Internet. In particular, we will discuss all-optical label switching routers scalable to 42 Petabit/sec switching capacity, experimental demonstrations of 11 hop cascaded operation, and a 477 km fiber link field trial. Introduction Optical packet switching routers allow integration ...

Frequent subgraph pattern mining is an important graph mining task. While the majority of existing systems focus on the transactional setting, where every transaction is a separate, independent graph, in recent years there has been an increasing interest in mining large networks. In particular, given a network (also called database graph) D, a pattern language L, a frequency measure freq and a ...

In this study, 31 household spray-type cleaning products from 10 categories were examined to identify the substances contained in these and evaluate their resulting toxicities. After substance detection via LC-QTOF-MS, suspect non-target screenings performed using UNIFI software. A total of 48 identified during screening. Among them, surfactant (freq. 22/31(71.0%)), plasticizer 23/31(74.2%)), a...

Understanding large-scale patterns in flow intermittence is important for effective river management. The duration and frequency of zero-flow periods are associated with the ecological characteristics of rivers and have important implications for water resources management. We used daily flow records from 628 gauging stations on rivers with minimally modified flows distributed throughout France...

A novel phase conjugator for active retrodirective array applications is presented. The circuit provides conversion gain as well as phase conjugating operation by using active devices, and results in a simple and compact design by using a common port for RF and IF signals. Measurement results indicate 3.2 dB conversion gain with RF-IF isolation of 20 dB. This phase conjugator can be used as a c...
