Problem statement: Lucas function is a special form of second-order linear recurrence relation. It is used in LUC cryptosystems. The performance of LUC cryptosystem depends on the size of public key, messages and two relatively primes. The increasing of size of these parameters will increase the computation time need to perform the LUC Cryptosystem computation. The efficiency means the quality ...

We propose to integrate diffractive axicons into solar cells as a light trap for increasing of light absorbing efficiency. Experimental work and numerical simulations are provided in this paper. The experimental measurements of light-to-electricity conversion efficiency are conducted using a laser with tunable wavelength.

Fair division methods offer guarantees to agents of the proportional size or quality of their share in a division of a resource (cake). These guarantees come with a price. Standard fair division methods (or ”cake cutting” algorithms) do not find efficient allocations (not Pareto optimal). The lack of efficiency of these methods makes them less attractive for solving multi-agent resource and tas...

Green et al. (1) report 2 y of increased evapotranspiration (ET; calculated as the difference between total precipitation and total runoff) and decreased water yield following watershed-scale amendment of soil with wollastonite (CaSiO3) at the Hubbard Brook Experimental Forest in the White Mountains of New Hampshire. The watershed manipulation study was planned and executed within the context o...

Mechanisms for facilitating people’s interactions with businesses, their governments, and each other are ubiquitous in today’s society. One emerging trend over the past decade, along with increasing computational power and bandwidth, has been a demand for higher levels of expressiveness in such mechanisms. This trend has already manifested itself in combinatorial auctions and generalizations th...

We thank Dr. Ortega for the opportunity to debate the concept that aging affects exercise efficiency. From the outset we must acknowledge that, indeed, some studies report an age-related reduction task efficiency during walking and other rather complex tasks (2, 12, 20, 21). However, in contrast, our recent study of leg cycling in centenarians (28), as well as other work focused more specifical...

In this work, we intend to answer the question if ability of the manager increase efficiency of incentive. We first create a mathematical model on a principal-agent relationship. The assumption is to consider the performance of the manager as a source of legitimacy which is a factor that will change the tolerance to inequity of the agent. Two main prediction of this model are: 1) if the perform...

Infertility has been linked to numerous factors in high producing dairy cattle in the last decades. The detection of estrus continues to present difficulties and, although progress has been made in regards to estrus synchronization and artificial insemination, the reproductive performance of dairy cows has not improved substantially. Moreover, in warm countries, summer heat stress is a major fa...

Uremic toxins are mainly represented by blood urine nitrogen (BUN) and creatinine (Crea) whose removal is critically important in hemodialysis (HD) for kidney disease. Patients undergoing HD have a complex illness, resulting from: inadequate removal of organic waste, dialysis-induced oxidative stress and membrane-induced inflammation. Here we report innovative breakthroughs for efficient and sa...
