HST/WFPC2 and VLT/ISAAC observations of PROPLYDS in the giant HII region NGC 3603

, 1999
We report the discovery of three proplyd-like structures in the giant HII region NGC 3603. The emission nebulae are clearly resolved in narrow-band and broad-band HST/WFPC2 observations in the optical and broad-band VLT/ISAAC observations in the near ...

Cracking the Code: Which Ocular Symptoms Predict Dry Eye Signs? Insights From a Large International Sicca Registry

Arthritis Care &Research, EarlyView.
Objective The study aimed to identify symptom‐based predictors of dry eye disease (DED) signs in the Sjögren's International Collaborative Clinical Alliance (SICCA) cohort. Methods We performed a retrospective analysis examining 16 ocular symptoms (most graded 0–4) and artificial tear (AT) use (graded 0–3) as predictors of DED signs (abnormal ocular ...

A Fuzzy Clustering with Optimized Cluster Head Selection Method in MANET

International Journal of Recent Technology and Engineering (IJRTE), 2019
MANET’S are a kind of Wireless ad hoc networks. The nodes in the networks are randomly move to different directions, self configurable and the network topology is various continuously and its act as a point-to-point, self-organisable, self-healing network.The network that assembled as an integral will be easily motile along with the nodes available in ...
