The effect of temperature on the formation and growth of monoatomic chains is investigated by extensive molecular d...
Inhalation of ambient ozone alters populations of lung macrophages. However, the impact of altered lung macrophage populations on the pathobiology of ozone is poorly understood. We hypothesized that subpopulations of macrophages modulate the response to ozone. We exposed C57BL/6 mice to ozone (2 ppm × 3 h) or filtered air. At 24 h after exposure, the lungs were harvested and digested and the ce...
Construction of a mammalian artificial chromosome (MAC) will develop our understanding of the requirements for normal chromosome maintenance, replication and segregation while offering the capacity for introducing genes into cells. Construction of MACs with telomere, centromere and replication function has been approached by two methods. The 'top down' strategy uses artificially induced chromos...
Mammalian artificial chromosomes (MACs) form in HT1080 cells after transfecting linear yeast artificial chromosome constructs minimally containing competent alphoid arrays, a selectable marker and terminal human telomere repeats. Restrictions on the structure of input DNA in MAC formation were investigated by transfecting circular or linear alphoid constructs with or without human telomere arra...
One aspect of Mobile Wireless Sensor Networks (MWSNs) is the MAC protocol, which is critical in terms of reliability, delay and energy consumption. This work begins with a literature review, showing that the majority of MWSN MACs are designed for hierarchical architectures, demonstrating that there is a lack of MACs intended for flat architecture MWSNs. Subsequently, we propose three new MAC pr...
Genetic and biochemical sperm integrity is essential to ensure the reproductive competence. However, spermatogenesis involves physiological changes that could endanger sperm integrity. DNA protamination and apoptosis have been studied extensively. Furthermore, elevated rates of aneuploidy and DNA injury correlate with reproductive failures. Consequently, this study applied the conventional sper...
Message authentication codes (MACs) are an essential primitive in cryptography. They are used to ensure the integrity and authenticity of a message, and can also be used as a building block for larger schemes, such as chosenciphertext secure encryption, or identity-based encryption. MACs are often built in two steps: first, the ‘front end’ of the MAC produces a short digest of the long message,...
We consider zero-error communication over a two-transmitter deterministic adversarial multiple access channel (MAC) governed by an adversary who has to the transmissions of both senders (hence called omniscient ) and aims maliciously corrupt communication. None encoders, jammer decoder is allow...
