The str operon of Streptomyces ramocissimus contains the genes for ribosomal proteins S12 (rpsL) and S7 (rpsG) and for the polypeptide chain elongation factors G (EF-G) (fus) and Tu (EF-Tu) (tuf). This kirromycin producer contains three tuf or tuf-like genes; tuf1 encodes the regular EF-Tu and is located immediately downstream of fus. In vivo and in vitro transcription analysis revealed a trans...

Problem statement: The heterogeneity in the choice of simulation platforms for real time scheduling stands behind the difficulty of developing a common simulation environment. A Discrete Event Simulation (DES) for a real time scheduling domain encompassing event definition, time advancing mechanism and scheduler has yet to be developed. Approach: The study focused on the proposed and the develo...

Dissemination of vector-transmitted pathogens depend on the survival and dispersal of the vector and the vector's ability to transmit the pathogen, while the host range of vector and pathogen determine the breath of transmission possibilities. In this study, we address how the interaction between dispersal and plant fidelities of a pathogen (stolbur phytoplasma tuf-a) and its vector (Hyalesthes...

We present our approach to real-time service-oriented scheduling problems with the objective of maximizing the total system utility. Different from the traditional utility accrual scheduling problems that each task is associated with only a single time utility function (TUF), we associate two different TUFs—a profit TUF and a penalty TUF—with each task, tomodel the real-time services that not o...

Elongation factor Tu (EF-Tu), encoded by tuf genes, carries aminoacyl-tRNA to the ribosome during protein synthesis. Duplicated tuf genes (tufA and tufB), which are commonly found in enterobacterial species, usually coevolve via gene conversion and are very similar to one another. However, sequence analysis of tuf genes in our laboratory has revealed highly divergent copies in 72 strains spanni...

Finding an appropriate end-to-end congestion control scheme for each type of flow, such as real-time or multicast flows, may be difficult. But it becomes even more complex to have these schemes be friendly among themselves and with TCP. The assistance of routers within the network for fair bandwidth sharing among the flows is therefore helpful. However, most of the existing mechanisms that prov...

WiMAX is a well-known broadband wireless access technology that supports multimedia transmission users. IEEE 802.16e has evolved into five quality of service (QoS) scheduling types for WiMAX uplink transmissions, but downlink transmission types have not yet been defined. To assist in this task, and to support efficient base station packet scheduling that takes QoS into account, I propose an ada...

We present time/utility function (TUF) algorithms that provide probabilistic assurance on timeliness behavior. A TUF, which is a generalization of the classical deadline constraint, specifies the utility of completing an application activity as a function of that activity’s completion time. The algorithms consider a stochastic model where activity execution times and arrivals are probabilistica...
