We show that, in the ideal-cipher model, triple encryption (the cascade of three independently-keyed blockciphers) is more secure than single or double encryption, thereby resolving a long-standing open problem. Our result demonstrates that for DES parameters (56-bit keys and 64-bit plaintexts) an adversary’s maximal advantage against triple encryption is small until it asks about 2 queries. Ou...

There is an enormous inequity in global health as well as research. Less than 10% of research funds are spent on the diseases that account for 90% of the global disease burden. This case study of north-south, south-south collaborations in Sri Lanka is a classic example of the issues faced by mental health researchers in low and middle income countries (LMICs). In this paper, work carried out by...

i=1 t i) k (87) We now comment on how the derivation changes when n = 2 and k 3. The case n 3 and k = 2 follows as well due to the symmetric functional equation (Equation 12). Note that up to Eq. 57 the derivation is valid when n = 2. Furthermore, note that the sum in Eq. 56 consists now of one term where l = j 1 = 1. Thus, Eq. 56 and Eq. 57 yield, using x i = z ij1 y j1 + z in y n (n=2, j 1 = ...

cystic fibrosis (cf) is a life-limiting autosomal recessive disorder affecting principally respiratory and digestive system . it is caused by cystic fibrosis transmembrane conductance regulator (cftr) gene mutation. the aim of this study was to determine the extent of repeat numbers and the degree of heterozygosity for c.3499+200ta(7_56) and d7s523 located in intron 17b and 1 cm proximal to the...

in the present investigation, shells of pistachio are used as adsorbents and they have been successfully used for the removal of blue 56, from water samples. the effect of various parameters such as: ph, amounts of adsorbents, size of adsorbent particles and contact time on removal processing were investigated. in this study freundlich absorption isotherms and langmuir were investigated . the e...

Nutrient (N) stress affects cotton growth, primary physiological processes andfiber properties. This study utilized two sunlit growth chambers to compare cotton(cv. TM-1) responses to two levels of N nutrition imposed at the onset of floweringstage of development, 100 and 0% of optimum N, in plants grown under otherwiseoptimal temperature and soil moisture conditions. Flowers and bolls were tag...
