In a previous study, we showed that Staphylococcus aureus supernate (SaS) is a potent agonist for both neutrophils and mononuclear cells. To further investigate the immunomodulating effects of SaS, the effect on different neutrophil receptors was studied. Expression of various neutrophil receptors, before and after treatment with SaS, was quantified by flow cytometry. We found that SaS treatmen...

Background and Purpose—Sleep apnea syndrome (SAS) is a common sleep disorder in stroke patients and is associated with decreased recovery and increased risk of recurrent stroke and mortality. The standard diagnostic test for SAS is poly(somno)graphy, but this is often not feasible in stroke rehabilitation settings. This study investigated the diagnostic value of nocturnal oximetry for screening...

Sequential aggregate signature (SAS) is a special type of public-key signature that allows a signer to add his signature into a previous aggregate signature in sequential order. In this case, since many public keys are used and many signatures are employed and compressed, it is important to reduce the sizes of signatures and public keys. Recently, Lee, Lee, and Yung (PKC 2013) proposed an effic...

While hard disk space is amazingly "cheap" nowadays, many of us programmers continue to find ourselves working in environments that have significant hard disk constraints. The ’always-ever-increasing-in-size’ data set too quickly eats up the hard disk "real estate" available to us which will give us immediate and direct access to our data. How many of us have found ourselves spending an inordin...

We evaluated and compared various broken-line regression models and SAS (SAS Inst. Inc., Cary, NC) procedures for estimating nutrient requirements from nutrient dose response data. We used the SAS (Version 9) procedures NLIN and NLMixed and the response data of Parr et al. (2003), who evaluated the isoleucine requirement of growing swine. The SAS NLIN was used to fit 2 different broken-line reg...

The single-question self-classification Stages of Change scales (SAS) for two modes of physical activity were compared with parallel staging methods. In Study 1, the participants (N = 50) completed SAS in a questionnaire and were then personally interviewed on their physical activity. In four fifths of the cases, SAS indicated the same stage as the interviewer's judgment. In Study 2, a represen...

Many SAS users experience challenges when working with large SAS datasets having millions of rows, hundreds of columns and size close to a gigabyte or even more. Often it takes enormous time to process these datasets which can have an impact on delivery timelines. Also, storing such datasets may cause shortage of permanent storage space or can exhaust the available memory. In order to handle th...

In today's business environment, enterprise computing deployments must be able to handle the challenges that companies face while adhering to IT standards. With the SAS platform being a multi-tiered environment consisting of components residing on client desktops, middle-tier Web servers, compute servers, and data assets, SAS customers are looking for ways to modernize their environment without...

This paper summarizes a real-world example of a factor analysis with a VARIMAX rotation utilizing the SAS@ System’s PROC FACTOR procedure. Each step you must undergo to perform a factor analysis is described -from the initial programming code to the interpretation of the PROC FACTOR output. The paper begins by highlighting the major issues that you must consider when performing a factor analysi...

Two hundred seven patients with DSM-IV Pathological Gambling Disorder completed both the Gambling Symptom Assessment Scale (G-SAS) and the Yale-Brown Obsessive-Compulsive Scale--modified for Pathological Gambling (PG-YBOCS) at baseline visit and weekly or biweekly thereafter during the 12-week study period. The week 1 to week 2 visit data were used to assess test-retest reliability. Weekly or b...
