This work reports a rigorous and comprehensive three-dimensional electromagnetic computation to investigate and design photoluminescence enhancement from a single silicon-vacancy center (SVC) in a nanodiamond crystal embedded in various metallic nanoantennae, each having a different geometry. The study demonstrates how each antenna design enhances the photoluminescence of SVCs in diamond. In pa...

The SVC (Static Var Compensator) based on voltage source converter (VSC) is used for voltage regulation in transmission and distribution system. The SVC can rapidly supply dynamic VARs required during system faults for voltage support. The apparent impedance is influenced by the reactive power injected or absorbed by the SVC, which will result in the under reaching or over reaching of distance ...

Superior vena cava (SVC) syndrome caused by malignant tumors in the upper mediastinum is not uncommon. Radiation therapy or endovascular treatment with stenting is the first choice of treatment to relieve symptoms. However, surgical treatment may be considered when the less invasive treatment modalities failed. In this report, we present two cases of severe symptomatic SVC syndrome as a result ...

Superior vena cava (SVC) syndrome is a medical condition resulting from the obstruction of the blood flow through the large central veins. Recently, central venous catheters have been reported as the increasingly common cause of this syndrome. We describe a 56-year-old woman with previous history of metastatic colon cancer, who had recently undergone central venous catheter insertion for her se...

Figure 1: Computed tomography (CT) scan of the chest. Axial image (A) shows a 2 × 3 cm mass in the anterior mediastinum and a tumour thrombus occluding the SVC and the azygos vein (arrows). On CT scan, the mediastinal mass does not have any connection either with the LBV or with the SVC. This unusual intravascular growth is due to the spread of the tumour into the LBV and SVC through the thymic...

The interconnected systems is continually increasing in size and extending over whole geographical regions, it is becoming increasingly more difficult to maintain synchronism between various parts of the power system. This paper work presents an advanced adaptive Particle swarm optimization technique to optimize the SVC controller parameters for enhancement of the steady state stability & overc...

INTRODUCTION Atrial fibrillation is the most common sustained heart arrhythmia. Premature beats arising from foci other than pulmonary veins have been related to its pathogenesis. METHODS AND RESULTS A 64-year-old female underwent superior vena cava (SVC) isolation after triggers were identified originating from the SVC following pulmonary vein isolation; immediately after SVC isolation, she ...

Pleural effusion is often a manifestation of the superior vena cava (SVC) syndrome. However, pleural effusion has never been reported to be a cause of the SVC syndrome. We report the case of a 68 yr old male patient who presented with SVC syndrome and respiratory failure, both attributable to an encapsulated pleural effusion over the right upper mediastinum. Simple drainage was performed as a d...

Approximately 15,000 cases of superior vena cava (SVC) obstruction are diagnosed in the United States annually. Malignancies (primarily lung cancer) are the underlying cause of 80-85% of cases, leaving 15-20% caused by various benign conditions, including sclerosing mediastinitis (the diagnosis in our case). Thrombolytic therapy and major advances in vascular techniques in recent years have imp...

We present a new R package which takes a numerical matrix format as data input, and computes clusters using a support vector clustering method (SVC). We have implemented an original 2D-grid labeling approach to speed up cluster extraction. In this sense, SVC can be seen as an efficient cluster extraction if clusters are separable in a 2-D map. Secondly we showed that this SVC approach using a J...
