While cloud computing is becoming a mainstream IT sourcing option, especially large companies struggle with the internal governance of cloud and the issue of shadow IT. This study takes a technological frames perspective to contrast the knowledge and expectations that business versus IT stakeholders have regarding cloud IT. Our interview data from 20 business and IT managers display the incongr...

This paper deals with simulation modeling of the vessel traffic in Delaware River. The purpose is to study the impact of deepening on the navigational efficiency in the River. In this regard, vessel calls to terminals, lightering and barge operations, tidal and navigational rules in the River, terminal and anchorage properties as well as vessel profiles are considered in the model. The simulati...

In the 1970s, technology was developed in order to network computers. This consisted of a set of communications protocols or rules, which enabled computers to connect and talk to each other. In 1983, the predecessor of theInternet adopted the protocol standard, which is now known as the Internet Protocol Suite otherwise known as TCP/IP. The Britannica Concise Encyclopedia defines these protocol...

Our work presents a new approach to developing, analyzing, and proving correctness of programs intended for execution on a quantum computer. We provide tools to write quantum as well as classical specifications, develop quantum and classical solutions for them, and analyses various properties of quantum specifications and quantum programs, such as implementability, time and space complexity, an...

103 The major benefits of knowledge management, particularly as it pertains to security measures, makes it critical that organizations have a mechanism for defining and identifying knowledge needs. With the explosion of the Internet and Web technologies as a medium of exchange, issues related to IT security have been growing exponentially. Protecting the organization's IT infrastructure from ha...

OBJECTIVE The purpose of this article is to detail an approach to CT colonographic screening that has evolved at one institution. CONCLUSION CT colonography is a rapidly advancing technology that has great potential for addressing a deadly but preventable disease-colorectal carcinoma. CT colonography is ideally suited for widespread screening of asymptomatic adults and has become an integral ...

All eukaryotes use multiple controls to restrict DNA replication to once per cell cycle. Nevertheless, inactivation of a single gene, cul-4, causes massive re-replication in Caenorhabditis elegans. A novel study explains this dramatic phenotype by demonstrating that the CUL-4 E3 ligase simultaneously controls two critical licensing factors: CDT-1 and CDC-6.

Hallux rigidus is a degenerative disease of the first metatarsalphalangeal (MTP) joint and affects 2.5% of people over age 50. Dorsal osteophytes and narrowed joint space leads to debilitating pain and limited range of motion. Altered gait mechanics often ensued as 119% of the body force transmit through the 1st MTP joint during gait cycle. Precise etiology remains under debate with trauma bein...

With modern computed tomography (CT) and magnetic resonance (MR) imaging equipment, the diagnosis of most renal masses is usually straightforward and accurate. The major question to be answered is whether the mass represents a surgical or nonsurgical lesion or, in some cases, if follow-up studies are necessary. This evaluation usually can be accomplished if a high-quality examination is perform...
