The mixing distribution is also sometimes called the mixing weights. There are a number of statistical estimation / unsupervised learning tasks associated with mixture models. Three such tasks are as follows (assuming an iid sample from some m? ∈M is given): 1. Density estimation: Here we assume that each distribution in M has a density. The task is to pick m̂ ∈ M such that m̂ is close to m? unde...

Context. Complex organic molecules (COMs) are commonly detected in and near star-forming regions. However, the dominant process release of these COMs from icy grains – where they predominately form to gas phase is still an open question. Aims. We investigate origin COM emission a high-mass protostellar source, CygX-N30 MM1, through high-angular-resolution interferometric observations over conti...

Context. Explaining the presence of complex organic molecules (COMs) in interstellar environments requires a thorough understanding physics and chemistry occurring interplay between gas phase surfaces. Experiments computer simulations are pivotal building comprehensive catalogue processes relevance for build up those environments. Aims. We combine experiments with tailored to study desorption d...

Abstract We present Atacama Large Millimeter/submillimeter Array Band 3 data toward five massive young stellar objects (MYSOs), and investigate relationships between unsaturated carbon-chain species saturated complex organic molecules (COMs). An HC 5 N ( J = 35–34) line has been detected from three MYSOs, where nitrogen (N)-bearing COMs (CH 2 CHCN CH CN) have detected. The spatial distributions...

Network infrastructure companies are now having difficulty surviving after the collapse of the dot coms. Drops of eighty percent in the market price of companies such as SUN Microsystems and CISCO do not allow for optimism in the hardware sector. An important part of the depreciation of these companies is due to the fall of the dot com companies, who were the principal customers of these manufa...

introduction: ophthalmic plaque radiotherapy using i-125 radioactive seeds in removable episcleral plaques is often used in management of ophthalmic tumors. radioactive seeds are fixed in a gold bowl-shaped plaque and the plaque is sutured to the scleral surface corresponding to the base of the intraocular tumor. this treatment allows for a localized radiation dose delivery to the tumor with a ...

This paper reports design of a ring oscillator using CS-COMS low noise logic family for mixed signal SOCs. Design has been implemented using 180nm technology with 1.8V supply voltage using CSCMOS logic. CS-CMOS logic efficiently reduce switching noise while maintaining the speed as compare to the other logics like CSL, CBL etc. After completion of the design authors have simulated the design in...

ABSTRACT Observations of gaseous complex organic molecules (COMs) in cold starless and prestellar cloud cores require efficient desorption the COMs their parent species from icy mantles on interstellar grains. With a simple astrochemical model, we investigate if mechanical removal ice fragments oblique collisions between grains two size bins (0.01 0.1 µm) can substantially affect COM abundances...
