    Notes: Abstract Stability properties of gravity receptor transduction mechanisms were investigated by recording action potentials from the eighth nerve of cats maintained at two spatial positions both with and without an added click perturbation. The cells were demonstrated to present directional sensitivity, multivaluedness and wandering of mean rate trajectories. To the wandering were fitted appropriate stability boundaries corresponding to recent theories of finite time stability. Results supported the hypothesis that physiological stimuli result in local deformations of a flexible trampoline-like macula.

    Notes: Abstract This paper identifies necessary and sufficient conditions for a penalty method to yield an optimal solution or a Lagrange multiplier of a convex programming problem by means of a single unconstrained minimization. The conditions are given in terms of properties of the objective and constraint functions of the problem as well as the penalty function adopted. It is shown among other things that all linear programs with finite optimal value satisfy such conditions when the penalty function is quadratic.

    Description / Table of Contents: Abstract A theorem is proved by means of Brouwer's theorem which allows to decide whether a given interval matrix [S] has the inclusion property relative to the unknown inverseA −1 of a known matrixA. It is demonstrated in which cases the theorem may be used and how to choose [S] in these cases.
    Notes: Zusammenfassung Mittels des Satzes von Brouwer wird ein Satz bewiesen, nach dem man entscheiden kann, ob eine gegebene Intervallmatrix [S] die Einschließungseigenschaft bezüglich der unbekannten InversenA −1 einer bekannten MatrixA hat. Es wird vorgeführt, in welchen Fällen der Satz anwendbar ist und wie [S] in diesen Fällen gewählt werden kann.

    Description / Table of Contents: Zusammenfassung Ein wichtiges Ergebnis der Komplexitätstheorie ist der Umbenennungssatz von E. M. McCreight, der besagt, daß es einen Algorithmus σ gibt, der alle Namen ϕi des Systems der Komplexitätsklassen in neue Namen ϕσ(i) überführt, derart, daß die neuen Namen die Schrittmaßbedingung „λi,n,m[ϕσ(i)(n)≦m] entscheidbar” erfüllen. Unsere Untersuchung der „gutartigen Funktionenklassen” zeigt, daß ein entsprechender Umbenennungsalgorithmus für diese Klassen nicht existiert.
    Notes: Abstract An important result in the theory of complexity classes is the naming theorem of E. M. McCreight, which states that the system of complexity classes can be renamed uniformly by a measured set of names. Our investigation of honesty classes shows that for these classes the analogous assertion is false. No measured transformation of programs renames correctly all honesty classes.

    Notes: Abstract The role of 0–1 programming problems having monotone or regular feasible sets was pointed out in [6]. The solution sets of covering and of knapsack problems are examples of monotone and of regular sets respectively. Some connections are established between prime implicants of a monotone or a regular Boolean functionβ on the one hand, and facets of the convex hullH of the zeros ofβ on the other. In particular (Corollary 2) a necessary and sufficient condition is given for a constraint of a covering problem to be a facet of the corresponding integer polyhedron. For any prime implicantP ofβ, a nonempty familyF(P) of facets ofH is constructed. Proposition 17 gives easy-to-determine sharp upper bounds for the coefficients of these facets whenβ is regular. A special class of prime implicants is described for regular functions and it is shown that for anyP in this class,F(P) consists of one facet ofH, and this facet has 0–1 coefficients. Every nontrivial facet ofH with 0–1 coefficients is obtained from this class.

    Notes: Conclusions An overview of these results indicates that SELECT is, in general, producing results in which elicited themes parallel those produced by frequency-based word selection. More importantly —and consonant with the impetus for development of the method — SELECT is delivering factors which are larger, more easily interpretable, and more discriminable than these available from frequency data and is doing so within the constraint of basic thematic identities.
