The paper contains preliminary results from an investigation comparing Linux and WindowsXP disk I/O using kernel-based software RAID on identical hardware. WindowsXP performance is shown to be substantially superior to Linux performance, for reasons not currently understood. One known problem with the Linux RAID driver is that in Linux 2.4 file I/O is synchronous and file operations are seriali...

Rate control is an important issue in video streaming applications for both wired and wireless networks. The widely accepted rate control method in wired networks, i.e. TCP friendly equation based rate control (TFRC) [1], is known to perform suboptimally in wireless networks. In previous work, we proposed MULTFRC as an end-to-end approach to fully utilize wireless bandwidth, modifying only appl...

PURPOSE This study investigated the impact of specific mutations in codon 12 of the Kirsten-ras (KRAS) gene on treatment efficacy in patients with metastatic colorectal cancer (mCRC). PATIENTS Overall, 119 patients bearing a KRAS mutation in codon 12 were evaluated. All patients received cetuximab-based first-line chemotherapy within the Central European Cooperative Oncology Group (CECOG), AI...

Particle Swarm Optimization (PSO) is an Evolutionary Algorithm (EA) that utilizes a swarm of particles to solve an optimization problem. Slow Intelligence System (SIS) is a learning framework which slowly learns the solution to a problem performing a series of operations. Moreover, Learning Automata (LA) are minuscule but effective decision making entities which are best suited to act as a cont...

BACKGROUND Treatment plan quality assurance (QA) is important for clinical studies and for institutions aiming to generate near-optimal individualized treatment plans. However, determining how good a given plan is for that particular patient (individualized patient/plan QA, in contrast to running through a checklist of generic QA parameters applied to all patients) is difficult, time consuming ...

The aim of the study was to assess the stability of all-in-one (AIO) parenteral admixture used for neonates, containing SMOFlipid, an alternative to soybean, an α-tocopherol-enriched lipid emulsion. SMOFlipid, consisting of soybean oil, medium chain triglycerides, olive oil and fish oil, was introduced commercially in 2005. Stability assays consisted of the assessment of the admixture’s macrosc...

Over the past 25 years, significant advances have been made in the management of patients with rectal cancer. Phase III studies have shown the efficacy of postoperative radiation therapy and chemotherapy in improving local control and survival of patients with resected stage II and III disease. Data from the randomized German CAO/ARO/AIO-94 trial of preoperative versus postoperative chemoradiat...
