We present our numerical code to perform syntheses of galaxy spectra. Our modified linear simplex algorithm has the advantage that no initial solution is required, the non-negativity for the individual contributions is guaranteed, additional spectral components can be added and individual wavelength regions can be weighted. Synthesizing the observed galaxy spectra with isochrone spectra we dete...

We present determination of age of clusters from 2.4 square degree region of the SMC bar. The photometric data were taken from the BVI maps of the SMC and catalog of clusters in this galaxy obtained during the OGLE-II microlensing survey. For 93 well populated SMC clusters their age is derived with the standard procedure of isochrone fitting. The distribution of age of cluster from the SMC is p...

We propose to take an artifact-centric approach design studies by leveraging the concept of boundary object. Design typically focus on processes and articulate decisions in a project-specific context with goal transferability. argue that could benefit from paying attention material conditions which teams collaborate reach outcomes. report study isochrone maps following cartographic generalizati...

Physical and numerical constraints in building up self-consistent population synthesis models are briefly analysed discussing their application to most of the current synthesis codes widely adopted in Galactic and extragalactic studies. Major focus is given in particular to the numerical effects of discrete isochrone sampling as well as to the energetic constraints for a proper normalization of...

Spontaneous action potentials were monitored from multiple sites in the bullfrog atrium using a voltage-sensitive merocyanine-rhodanine dye together with a 100-element photodiode matrix array, and we have assessed the spread of the excitation from the pacemaker. Isochrone curves of conduction were obtained by timing the initiation of the action potential-related optical signals: we constructed ...

BACKGROUND We have developed a noninvasive isochrone activation imaging (AI) system with 3-dimensional (3D) speckle tracking echocardiography (STE), which allows visualization of the wavefront image of mechanical propagation of the accessory pathway (ACP) in Wolff-Parkinson-White syndrome. METHODS AND RESULTS Patients with manifest Wolff-Parkinson-White syndrome were imaged in 3D-STE AI mode,...

We present a morphological analysis of the feature-rich 2MASS LMC colormagnitude diagram, identifying Galactic and LMC populations and estimating the density of LMC populations alone. We also present the projected spatial distributions of various stellar populations. The conditions that prevailed when 2MASS observed the LMC provided 10σ limiting sensitivity for J <∼ 16.3, H <∼ 15.3, Ks <∼ 14.7....
