Countermeasures as Lightning, not a Lightning Bug: Illuminating the Legal Doctrine

open access: yesThe Cyber Defense Review, 2023
Mark Twain famously observed that the difference between the “right word and the almost right word is the difference between lightning and a lightning bug.” Similarly, here, the term ‘countermeasures’ has a particular textual meaning under international ...

More Quasi-Complementary Sequence Sets from Difference Sets and Almost Difference Sets

open access: yes2019 Ninth International Workshop on Signal Design and its Applications in Communications (IWSDA), 2019
A quasi-complementary sequence set (QCSS) is a set of two-dimensional matrices which has low correlation sums of rows for all non-trivial time shifts. In multi-carrier code-division multiple-access (MC-CDMA) communications, QCSSs can be utilized to achieve low interference performance.

Generating Almost Descending Sequences to Reduce the Number of Movements in Sorting

open access: yesIEEE Access, 2022
Sorting algorithms usually generate strictly descending sequences. However, almost descending sequences may be sufficient to fulfill our needs in practice, and the number of movements needed for generating such sequences can be greatly reduced. We call a

The smallest known genomes of multicellular and toxic cyanobacteria: comparison, minimal gene sets for linked traits and the evolutionary implications. [PDF]

open access: yesPLoS ONE, 2010
Cyanobacterial morphology is diverse, ranging from unicellular spheres or rods to multicellular structures such as colonies and filaments. Multicellular species represent an evolutionary strategy to differentiate and compartmentalize certain metabolic ...
