Life-history traits of Indian river shad Gudusia chapra (Hamilton, 1822) in the Mahananda River (tributary of the Ganges River) of northwestern Bangladesh [PDF]
Songklanakarin Journal of Science and Technology (SJST), 2021 For the first time, we describe the life-history traits including growth pattern, condition factors including (relative weight, WR), form factor (a3.0), size at sexual maturity (Lm), and natural mortality (Mw) of Gudusia chapra in the Mahananda River ...

Conditions for Factor (in)Determinacy in Factor Analysis [PDF]
Psychometrika, 1998 The subject of factor indeterminacy has a vast history in factor analysis (Guttman, 1955; Lederman, 1938; Wilson, 1928). It has lead to strong differences in opinion (Steiger, 1979). The current paper gives necessary and sufficient conditions for observability of factors in terms of the parameter matrices and a finite number of variables.

On conditional permutability and factorized groups [PDF]
Annali di Matematica Pura ed Applicata (1923 -), 2013 Two subgroups and of a group are said to be totally completely conditionally permutable (tcc-permutable) if permutes with for some , for all and all . In this paper, we study finite products of tcc-permutable subgroups, focussing mainly on structural properties of such products. As an application, new achievements in the context of formation theory are

Conditions for the existence of maximal factorizations
Fuzzy Sets and Systems, 2020 Extending classical algorithms for ordinary weighted or string-to-string automata to automata with underlying more general algebraic structures is of significant practical and theoretical interest. However, the generalization of classical algorithms sets certain assumptions on the underlying structure.
