Purpose: Although Verification and Validation (V&V) are two prevalent processes for the industry, there is still vagueness regarding their implementation. These processes are linked with appraisal costs and can occupy up to 70% of the total design time. This work sets out to provide clarity on the current use of V&V pr... |
The depth‐averaged (2D) lubrication theory is often adopted to simulate Newtonian flow in rough fractures. This approach, which is computationally much less expensive than using 3D CFD solvers, allows addressing large ensembles of stochastic fracture realizations. For creeping flow, the degree of approximation introduc... |
This paper investigates the power mode management problem for an IEEE 802.11-based mobile ad hoc network (MANET) that allows mobile hosts to tune to the power-saving (PS) mode. There are two major issues that need to be addressed in this problem: (a) wakeup prediction and (b) neighbor discovery. The former is to delive... |
ORPphilins are bioactive natural products that strongly and selectively inhibit the growth of some cancer cell lines and are proposed to target intracellular lipid-transfer proteins of the oxysterol-binding protein (OSBP) family. These conserved proteins exchange key lipids, such as cholesterol and phosphatidylinositol... |

Through a user study we compare the performance of this interface to the performance of a common scrollable 2D list of thumbnails in a grid arrangement. Our evaluation shows that t... |
Sickle cell intrahepatic cholestasis (SCIC) is a rare but fatal complication of sickle cell disease. It is found mainly in homozygous sickle cell disease. To date, there are no standard diagnostic criteria or well-established therapeutic approaches to this condition. Herein, we report this case of a 48-year-old man wit... |
As has been shown and extensively dealt with in early and more recent scholarship, Neo-Assyrian palatial wall reliefs went through many thematic changes throughout their two hundred and fifty years of existence. One of their conspicuous traits was a gradual abandoning of magical-religious subject matters, represented b... |
INTRODUCTION |
Moderate hyperhomocysteinemia is a causal risk factor for atherosclerosis and venous thromboembolism. Recent researches have tried to find out a causal relationship. However, only a small number of cases have been reported on hyperhomocysteinemia and cerebral venous thrombosis in the world medical literature. |
CASE REPORT |
We present the case of a 21 years old woman, and oral contraceptives taker, who consulted for a one week clinical picture of biparietal headache, nausea and vomiting. Examination revealed bilateral papilledema, and subsequent CT scan, MRI and MR angiography showed thrombosis of the left lateral sinus. Immunologic tests... |
DISCUSSION |
The 70 percent of the patients with thrombosis of the cerebral venous sinuses present hypercoagulable states, including moderate hyperhomocysteinemia. Several mechanisms are proposed for venous thrombosis in hyperhomocysteinemia, homocysteine induced endothelial dysfunction between others. Otherwise, oral contraceptive... |
In this paper, we aim to contribute to the elaboration of a framework for the systematic periodisation of health social movement organisations (HSMOs). Drawing on historical and contemporaneous data on two organisations that identify as Alzheimer's disease movement organisations (the Alzheimer's Society in Britain and ... |
Interference alignment is known to be degrees of freedom optimal for the K-user interference channel. As a result, many alignment-based schemes have been developed in literature. However, most schemes are not easy to implement due to the requirements for a large number of dimensions and an extensive exchange of channel... |
The problem of finding information processing means to support the detection of Toxocariasis parasitic disease is considered. It is pointed out that due to the polymorphism of symptoms this disease is often overlooked. Its presence can be confirmed or rejected based on expensive serological tests. It is postulated that... |

OBJECTIVE |
To investigate the relationship of the clinical appearance, histological characteristics, bacterial culturing, and messenger RNA (mRNA) expression of RANTES, interleukin 6, and interleukin 12, as well as the occurrence of endothelial adhesion molecules, in inflammatory diseased maxillary sinus mucosa in critically ill ... |
DESIGN |
Prospective case series. |
SETTING |
General intensive care unit and neurosurgical intensive care unit of a tertiary care hospital. |
SUBJECTS |
Seven critically ill patients, nasotracheally intubated or tracheotomized, who received ventilator treatment for more than 7 days and treatment with antibiotics. |
INTERVENTIONS |
Bilateral biopsy specimens of antral mucosa were obtained at sinoscopy. Reverse transcriptase-polymerase chain reaction was used to detect the cytokine mRNAs in situ on paraformaldehyde-fixed tissue, and intercellular adhesion molecule 1, vascular cell adhesion molecule 1, E-selectin, and P-selectin were analyzed by im... |
RESULTS |
Macroscopic and histological appearance varied and showed moderate to pronounced inflammation in 6 antra. All 4 bacterially infected antra showed mRNA RANTES (P=.005). No correlation was found for interleukin 6 and interleukin 12. Up-regulation of P-selectin in all cases and sparse expression of vascular cell adhesion ... |
CONCLUSION |
We find an indication that RANTES is more prevalent in bacterial sinusitis.Effects of outpatient treatment on risk of arrest of adults with serious mental illness and associated costs. |
OBJECTIVE |
This study examined whether possession of psychotropic medication and receipt of outpatient services reduce the likelihood of posthospitalization arrest among adults with serious mental illness. A secondary aim was to compare service system costs for individuals who were involved with the justice system and those who w... |
METHODS |
Claims data for prescriptions and treatments were used to describe patterns and costs of outpatient services between 2005 and 2012 for 4,056 adult Florida Medicaid enrollees with schizophrenia or bipolar disorder after discharge from an index hospitalization. Multivariable time-series analysis tested the effects of med... |
RESULTS |
A total of 1,263 participants (31%) were arrested at least once during follow-up. Monthly medication possession and receipt of outpatient services reduced the likelihood of any arrests (misdemeanor or felony) and of misdemeanor arrests. Possession of medications for 90 days after hospital discharge also reduced the lik... |
CONCLUSIONS |
Routine outpatient treatment, including medication and outpatient services, may reduce the likelihood of arrest among adults with serious mental illness. Medication possession over a 90-day period after hospitalization appears to confer additional protection. Overall, costs were lower for those who were not arrested, e... |
