A set of sensors establishes barrier coverage of a given line segment if every point of the segment is within the sensing range of a sensor. Given a line segment I, n mobile sensors in arbitraryâ€¦ (More)

We give a new local test, called a Half-Space Proximal or HSP test, for extracting a sparse directed or undirected subgraph of a given unit disk graph. The HSP neighbors of each vertex are unique,â€¦ (More)

We show that every plane graph with maximum face size four whose all faces of size four are vertex-disjoint is cyclically 5-colorable. This answers a question of Albertson whether graphs drawn in theâ€¦ (More)

Self-assembly is an autonomous process by which small simple parts assemble into larger and more complex objects. Self-assembly occurs in nature, for example, when atoms combine to form molecules,â€¦ (More)

We consider n mobile sensors located on a line containing a barrier represented by a finite line segment. Sensors form a wireless sensor network and are able to move within the line. An intruderâ€¦ (More)

We consider the Combinatorial RNA Design problem, a minimal instance of RNA design where one must produce an RNA sequence that adopts a given secondary structure as its minimal free-energy structure.â€¦ (More)

Motivated by a problem in the design of optical networks, we ask when a graph has a spanning spider (subdivision of a star), or, more generally, a spanning tree with a bounded number of branchâ€¦ (More)

Complex intracellular signaling networks monitor diverse environmental inputs to evoke appropriate and coordinated effector responses. Defective signal transduction underlies many pathologies,â€¦ (More)

Consider n sensors whose positions are represented by n uniform, independent and identically distributed random variables assuming values in the open unit interval (0, 1). A natural way to guaranteeâ€¦ (More)

Motivated by the wavelength division multiplexing in alloptical networks, we consider the problem of finding an optimal (with respect to the least possible number of wavelengths) set of f + 1â€¦ (More)
