BACKGROUND Macrolane is a stabilized, hyaluronic acid-based gel that has been available since 2007 as a minimally invasive, nonpermanent option for breast enhancement. However, numerous controversies pertaining to its side effects have highlighted the need for studies involving larger groups of patients. OBJECTIVES The authors sought to determine complications of Macrolane injections for brea...

Connectivity augmentation problems ask for adding a set of at most k edges whose insertion makes a given graph satisfy a specified connectivity property, such as bridge-connectivity or biconnectivity. We show that, for bridge-connectivity and biconnectivity, the respective connectivity augmentation problems admit problem kernels with O(k) vertices and links. Moreover, we study partial connectiv...

A novel data augmentation method suitable for wearable sensor data is proposed. Although numerous studies have revealed the importance of the data augmentation to improve the accuracy and robustness in machine-learning tasks, the data augmentation method that is applicable to wearable sensor data have not been well studied. Unlike the conventional data augmentation methods, which are mainly dev...

b a ckground:   eco-faunistic  studies  are  inevitable  step  in  environmental  researches.  aquatic  organisms  like caddisflies are known as biological indicators for water quality assessment and water resource management. they have special role for energy flow in the freshwater habitats as food web and food chain among aquatic creatures. methods: in addition to an extensive literature revi...

phytoplanktons are the first bio- indicators of pollution in aquatic ecosystems. phytoplankton assemblage and aquatic ecosystems are always influenced by environmental factors therefore these environmental changes and threats must be understood in any ecosystem. phytoplankton are inexpensive and readily available bio- indicators. in the present study, phytoplankton were used to study the sefid ...

BACKGROUND A large, multicenter, 10-year observational study is being conducted to compare the long-term safety and effectiveness of Natrelle silicone breast implants with saline implants or national norms. Study baseline data and surgical characteristics are reported here. METHODS Women seeking primary augmentation, revision-augmentation, primary reconstruction, or revision-reconstruction pa...

Aortic augmentation index, a measure of central systolic blood pressure augmentation arising mainly from pressure-wave reflection, increases with vascular aging. The augmentation index is influenced by aortic pulse-wave velocity (related to aortic stiffness) and by the site and extent of wave reflection. To clarify the relative influence of pulse-wave velocity and wave reflection on the augment...

BACKGROUND Breast augmentation with subglandular versus subpectoral implants may differentially impact the early detection of breast cancer and treatment recommendations. The authors assessed the impact of prior augmentation on the diagnosis and management of breast cancer in women undergoing mastectomy. METHODS Breast cancer diagnosis and management were retrospectively analyzed in all women...

Global Navigation Satellite (GPS) system has gradually come of age and has found itself a place as standard Navigation equipment in most aircraft. However, data from a GPS Receiver is not reliable enough for it to be used as a primary or sole source of navigation information. As a result GPS only system is allowed to be used only as a supplemental means of navigation for aircraft in the less cr...
