The origin of blue straggler stars (BSS) in globular clusters (GCs) is still not fully understood: they can form from stellar collisions, or through mass-transfer in isolated, primordial binaries (PBs). In this paper we use the radial distribution of BSS observed in four GCs (M3, 47 Tuc, NGC 6752 and ω Cen) to investigate which formation process prevails. We find that both channels coexist in a...

PURPOSE To compare the protective properties and ease of manipulation during cataract surgery of corneal coating with a gel (eyeDRO; AL.CHI.MI.A. S.R.L, Italy) and corneal irrigation with balanced salt solution (BSS). METHODS We analyzed the data of 51 patients receiving either eyeDRO or BSS during routine cataract surgery performed within a 20-day period in 2016. The selected parameters were...

UsingHST-WFPC2 observations in two ultraviolet (UV) filters (F225W and F336W) of the central region of the high density Galactic Globular cluster (GGC) M80 we have identified 305 Blue Straggler Stars (BSS) which represents the largest and most concentrated population of BSS ever observed in a GGC. We also identify the largest, clean sample of evolved BSS yet found. The high stellar density alon...

This survey aimed to assess the conceptualization of and utilization of blood stasis syndrome within traditional East Asian medicine among Doctors of Korean Medicine (DKMs). A survey was conducted with 22 questions classified into four categories (the present status, problems and requirements of a BSS diagnosis; the concept, diseases and prescriptions regarding BSS; the present status and probl...

Frequency domain Blind Source Separation (BSS) is shown to be equivalent to two sets of Adaptive Beamformers (ABFs). The minimization of the off-diagonal components in the BSS update equation can be viewed as the minimization of the mean square error in the ABF. The unmixing matrix of the BSS and the filter coefficients of the ABF converge to the same solution in the mean square error sense if ...

This paper overviews a total solution for frequencydomain blind source separation (BSS) of convolutive mixtures of audio signals, especially speech. Frequency-domain BSS performs independent component analysis (ICA) in each frequency bin, and this is more efficient than time-domain BSS. We describe a sophisticated total solution for frequency-domain BSS, including permutation, scaling, circular...

The objective of this study was to determine if a sulfur binder, bismuth subsalicylate (BSS), alone or combined with monensin (MON) could decrease the production of HS by rumen microbes. In Exp. 1, two 24-h batch culture incubations were conducted using a substrate consisting of 50% corn, 40% distillers grains, 9.75% hay, and 0.25% mineral premix, on a DM basis. Five treatments including BSS co...

Signal processing methods for speech enhancement are of vital interest for communications equipments. In particular, multichannel algorithms, which perform spatial filtering to separate signals that have overlapping frequency content but different spatial origins, are important for a wide range of applications. Two of the most popular multichannel methods are blind signal separation (BSS) and b...

Recent surveys of the blue straggler (BS) population in the galactic globular cluster M3 (NGC 5272) give the rst complete characterization of the number density of BSs as a function of radius over an entire globular cluster. The BSs in M3 are overabundant at large radii, and signiicantly underabundant at intermediate radii. Here we present the result of a simulation of the dynamical evolution o...

To fully exploit the benefits of heterogeneous network (HetNet), in which macro BSs (base stations) and small BSs coexist, the intercell interference mitigation and radio resource management has attracted general attention. We propose a cross-tier cooperative transmission strategy with precoding at downlink OFDMA resource block level, supported by macro BSs and small BSs ,to reduce the intercel...
