Complete Arcs in Steiner Triple Systems

A complete arc in a design is a set of elements which contains no block, and is maximal with respect to this property. The spectrum of sizes of complete arcs in Steiner triple systems is determined without exception here.

Constructions for generalized Steiner systems GS (3, 4, v , 2)

Generalized Steiner systems GS (3, 4, v, 2) were first discussed by Etzion and used to construct optimal constant weight codes over an alphabet of size three with minimum Hamming distance three, in which each codeword has length v and weight four. Not much is known for GS (3, 4, v, 2)s except for a recursive construction and two small designs for v = 8, 10 given by Etzion. In this paper, more s...

Li(V0.5Ti0.5)S2 as a 1 V lithium intercalation electrode

Graphite, the dominant anode in rechargeable lithium batteries, operates at ∼ 0.1 V versus Li(+)/Li and can result in lithium plating on the graphite surface, raising safety concerns. Titanates, for example, Li4Ti5O12, intercalate lithium at ∼ 1.6 V versus Li(+)/Li, avoiding problematic lithium plating at the expense of reduced cell voltage. There is interest in 1 V anodes, as this voltage is s...

Existence of Generalized Steiner Systems GS(2, 4, v, 2)

Generalized Steiner systems GS(2, 4, v, 2) were first discussed by Etzion and used to construct optimal constant weight codes over an alphabet of size three with minimum Hamming distance five, in which each codeword has length v and weight four. Etzion conjectured its existence for any integer v ≥ 7 and v ≡ 1 (mod 3). The conjecture has been verified for prime powers v > 7 and v ≡ 7 (mod 12) by...
