We present the first constant-round, tree-based, group key exchange protocol based on SIDH with logarithmic-order communication and memory complexity, where only previous isogeny-based exchange, SIBD, has linear-order complexity. call our supersingular isogeny tree-based (SIT). show that satisfies post-quantum security through a reduction to decisional Diffie–Hellman (SSDDH) problem in model of...

after passing more than one decade of appearance of digital libraries in iran, they couldn’t meet their real mission, which is responding to audience needs. surely, this problem is affected by potentially and real factors. so this research wants to recognize resistant factors and driving factors by recourse oriented approach, and then to fit them in integrated model.research method which we app...

Gastrointestinal (GI) complications during diabetes mellitus (DM) are common. Attempts to ascribe changes in the glycemic state to the altered GI (gastrointestinal) motility in experimental models yielded varied results. In the present study the possible cause-effect relationship between the changes in the glycemic, insulinemic states and small intestinal transit (SIT) in normal mice was examin...

An interactive programme, incorporating a deterministic model of tsetse (Diptera: Glossinidae) populations, was developed to predict the cost and effect of different control techniques applied singly or together. Its value was exemplified by using it to compare: (i) the sterile insect technique (SIT), involving weekly releases optimized at three sterile males for each wild male, and (ii) insect...

We present a simple mathematical model to replicate the key features of the sterile insect technique (SIT) for controlling pest species, with particular reference to the mosquito Aedes aegypti, the main vector of dengue fever. The model differs from the majority of those studied previously in that it is simultaneously spatially explicit and involves pulsed, rather than continuous, sterile insec...

The sterile insect technique (SIT) is an appealing method for managing mosquito populations while avoiding the environmental and social costs associated with more traditional control strategies like insecticide application. Success of SIT, however, hinges on sterile males being able to compete for females. As a result, heavy and/or continued use of SIT could potentially diminish its efficacy if...

Geometrical structure, nuclear magnetic resonance (N1,1It) chemical shielding tensors, and chemical shiftsof silicon and carbon nucler are investigated for twn infinite size zigzag and armchair single-walled siliconcarbide nanotabes (SiCNTs). Geometrical structures of SieNTs, Sit bonds and bond angles of St and Cvertices in both zigzag and armchair nanotubes, Indicate that bond lengths are appr...

The five-times-sit-to-stand test (FTSS) is an established assessment of lower limb strength, balance dysfunction and falls risk. Clinically, the time taken to complete the task is recorded with longer times indicating increased falls risk. Quantifying the movement using tri-axial accelerometers may provide a more objective and potentially more accurate falls risk estimate. 39 older adults, 19 w...
