The SCN neurons have been categorized into several different subgroups [41], [42], and it is quite possible that the heterogeneity of the Ca2+ buffering systems may underlie the existence of these subgroups.
In the rodent (prefrontal) cortex, interneurons have been categorized into several different subtypes based on their electrophysiological, morphological, and chemical properties (Kawaguchi and Kondo 2002; Beierlein et al. 2003; Couey et al. 2007; Ascoli et al. 2008; Fanselow et al. 2008; Van Aerde et al. 2009).
4) Flexible loads can be categorized into several different groups according to their temporal availabilities and individual characteristics.
Compared to the conventional specification in which age is categorized into several predefined groups, the proposed method is more flexible and able to produce quantitatively explicit results.
Multiaxial fatigue analysis can be categorized into several viewpoints, i.e. empirical formulae, methods based on stress invariants, critical plane approaches, models using averages of stress quantities and energetic considerations.
The tuned mass damper (TMD) has been applied to the machining vibration control widely, and it is categorized into several groups depending on the available degrees of freedom (DOF).
The catalysts commonly used for biodiesel production are categorized into several types: homogeneous catalysts (sodium hydroxide, potassium hydroxide, sulfuric acid, etc).[5], heterogeneous catalysts (cation-exchange resin, hydrotalcites, etc)., and enzymes (Chromobacterium viscosum, Candida rugosa, and Porcine pancreas)[6].
Current Hsp90 inhibitors are categorized into several classes based on distinct modes of inhibition, including (i) blockade of ATP binding, (ii) disruption of co-chaperone/Hsp90 interactions, (iii) antagonism of client/Hsp90 associations and (iv) interference with post-translational modifications of Hsp90.
The majority of these foods were categorized into several major areas: (1) frozen foods; (2) fresh produce and/or highly perishable foods requiring refrigeration; (3) fast foods and prepared foods; (4) shelf-stable foods; (5) specialized study and non-retail (point of production) foods; and (6) foods from remote areas (e.g. American Indian reservations).
Of particular interest in the k-means clustering were the results for dive descent where behavior spectra were categorized into several elements sequentially (elements 13, 14, 15, 16, 17, and 10).
