Individuals within organizations are beginning to make an important realization: more information technology (IT) usage in the workplace can, at times, lead to productivity losses. We conceptualize this frequently observed, but largely ignored phenomenon as technology overload, when additional technology tools begin to crowd out one’s productivity instead of enhancing it. We found support for t...

Recent collapses of SIP servers in the carrier networks indicates two potential problems of SIP: (1) the current SIP design does not easily scale up to large network sizes, and (2) the built-in SIP overload control mechanism cannot handle overload conditions effectively. In order to help carriers prevent widespread SIP network failure effectively, this chapter presents a systematic investigatio...

conclusions it seems that severe pah aggravates the rv function more severely. results significant tricuspid regurgitation was more prevalent in the pah group than in the ps group (61% vs. 18.5%; p < 0.001). the abnormalities in the rv myocardial performance index, rv areas, and rv fractional area change were significantly more robust in the pah group (all ps < 0.05) despite the higher net rv s...

background: iron chelators are an important part of management of patients with thalassemia. it is prudent to compare efficacy of different iron chelators in treatment of iron overload in these patients who receive regular blood transfusion. we aimed to compare the efficacy and safety of available oral iron chelator; deferasirox (exjade®) with deferasirox (osveral®) in reducing iron overload in...

BACKGROUND High rates of volume overload hospitalizations may indicate inadequate dialysis facility fluid management. Administrative claims databases are often used to study such outcomes, but these data are generated for billing purposes and may not capture clinical nuance. It is unknown if volume overload admissions can be correctly identified in administrative data and if a single claims-bas...

The amount of email people have to deal with is overwhelming. People tend to work extra hours in order to keep up with their email, and some are even getting ill because of all the stress this overload generates. This paper describes the causes and symptoms of email overload, the strategies people use to deal with it and possible solutions towards the problem. These are given with the help of a...

Design, setting, participants, & measurements Fluid status was optimized prospectively in 55 chronic hemodialysis patients over 3 months (November 2011 to February 2012). Predialysis fluid overload was measured weekly using the Fresenius Body CompositionMonitor. Time-averaged fluid overload was calculated as the average between preand postdialysis fluid overload. The study aimed to bring the ti...

In winter wheat, grain development is asynchronous. The grain number and grain weight vary significantly at different spikelet and grain positions among wheat cultivars grown at different plant densities. In this study, two winter wheat (Triticum aestivum L.) cultivars, 'Wennong6' and 'Jimai20', were grown under four different plant densities for two seasons, in order to study the effect of pla...

Wireless networks are currently experiencing more overload situations than their wireline counterparts because of explosive mobile traffic growth, unpredictable traffic behavior, service differentiated traffic shedding, etc. Even though extensive research work on network overload control in general is going on, the economic aspect of the overload problem has received very little attention. Mana...

Mobile Switching Centers (MSCs) in wireless telecommunication networks must implement signaling overload controls to maintain acceptable performance during periods of high load especially due to fast changing hot spots resulting from user mobility. An MSC’s signaling load comprises a variety of service requests, some more important than the others, and it must treat them differentially under ov...
