Does a new product spread faster among heterogeneous or homogeneous consumers? We analyze this question using the stochastic discrete Bass model in which consumers may differ their individual external influence rates [Formula: see text] and internal text]. When network is complete heterogeneity only manifested text], it always slows down diffusion, compared with corresponding network. When, how...

We present fluorine abundances in seven red-giant members of the globular cluster M4 (NGC 6121). These abundances were derived from the HF (1–0) R9 line at 2.3357μm in high-resolution infrared spectra obtained with the Phoenix spectrograph on Gemini-South. Many abundances in the target stars have been studied previously, so that their overall abundance distributions are well-mapped. The abundan...

Practical implications for stakeholders:  Increasing consumer awareness of health issu for change in the products available to them. T for meat products with reduced fat, salt and functional foods.  Processed meat products represent complex s components. Processes and forces operating a the product.  By improving our understanding of the impa ingredients on technological and sensory perfo ve...

A microbial fraction library has been constructed as a part of RIKEN Natural Products Depository (NPDepo) to discover and isolate novel metabolites with unique biological activity from microbial sources efficiently and rapidly. The fraction library was made by a systematic separation method based on basic chromatographic techniques. Each fraction in the library was analyzed by liquid chromatogr...

We have obtained high resolution mid-infrared images of the high mass protostar NGC 7538 IRS 1 using Michelle on Gemini North and find that the circumstellar dust associated with this source is extended on both large and small scales. The large-scale mid-infrared emission is asymmetric about the peak of IRS 1, being more extended to the northwest than the southeast. The position angle of the mi...
