(0, 1)-Matrices with No Half-Half Submatrix of Ones

We consider the minimum number of zeroes in a 2m 2n (0; 1)-matrix M that contains no m n submatrix of ones. We show that this number, denoted by f(m; n), is at least 2n + m + 1 for m n. We determine exactly when this bound is sharp and determine the extremal matrices in these cases. For any m, the bound is sharp for n = m and for all but nitely many n > m. A general upper bound due to Gentry, f...

The Attachment Paradox: How Can So Many of Us (the Insecure Ones) Have No Adaptive Advantages?

Bowlby's (1969/1982) attachment theory has generated an enormous body of research and conceptual elaborations. Although attachment theory and research propose that attachment security provides a person with many adaptive advantages during all phases of the life cycle, numerous studies indicate that almost half of the human species can be classified as insecurely attached or insecure with respec...

"No Good Reason to Remove Features" - Expert Users Value Useful Apps over Secure Ones

Application sandboxes are an essential security mechanism to contain malware. Yet, they are seldom used on Desktops. We hypothesise this is because sandboxes are incompatible with plugins, and with APIs used to implement a wide variety of Desktop features. To verify this, we interviewed 13 expert users about their app appropriation decisions, and illustrate how they recruit values like usefulne...

Feedback capacity and coding for the BIBO channel with a no-repeated-ones input constraint

In this paper, a general binary-input binary-output (BIBO) channel is investigated in the presence of feedback and input constraints. The feedback capacity and the optimal input distribution of this setting are calculated for the case of an (1,∞)-RLL input constraint, that is, the input sequence contains no consecutive ones. These results are obtained via explicit solution of an equivalent dyna...
