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...

A novel UV transparent conducting films based on Sb2O3/Ag/Sb2O3 (SAS) structure, which were prepared by an electron-beam thermal evaporation at room temperature. This SAS exhibits excellent electrical, optical and stable properties. Especially for UV region, the SAS has high transmittance of 80% at 306 nm and 92% at 335 nm, meanwhile achieving low sheet resistance ( ≤ 10 Ω sq-1). The UV OLED ba...

Semen analysis was performed according to conventional procedures. Serum follicle-stimulating hormone, luteinizing hormone and testosterone levels were quantified. Psychological anxiety and depression...

Like many organizations, the health care quality improvement industry is charged with doing more with less. This can only be accomplished by careful scheduling of resources. Geographical differences in adherence to clinical guidelines have been demonstrated. In this paper, geographical analyses are used both to identify regions and providers for healthcare quality improvement targeting and to i...

This paper presents an overview of the SAS® approach to supplier management, focusing on the use of SAS’ wellestablished optimization expertise to aid in selecting and evaluating suppliers. The supplier management solutions are explored individually and are shown in the context of a complete spectrum of SAS supply chain solutions.

Stimulant dependence is associated with neuropsychological impairments. Here, we summarize and integrate the existing neuroimaging literature on the neural substrates of neuropsychological (dys)function in stimulant dependence, including cocaine, (meth-)amphetamine, ecstasy and nicotine dependence, and excessive caffeine use, comparing stimulant abusers (SAs) to nondrug using healthy controls (...

CSF is thought to flow continuously from the site of production in the ventricles into interconnected spaces; i.e. cisterns and subarachnoid spaces (SASs). Since the SAS of the optic nerve is defined by a cul-de-sac anatomy, it is not evident how local CSF might recycle from that region to the general SAS. The concept of free communication of CSF has recently been challenged by the description ...
