IDEA is a block cipher designed by Xuejia Lai and James L. Massey and was first described in 1991. IDEA does not vary the constant in its key schedule. In [1], Donghoon Chang and Moti Yung showed that there may be a weakness of hash function based on block cipher whose key schedule does not use various constants. Based on their result, we investigate the security of double block length compress...

A 33-year-old nulligravid Filipino woman was admitted to the gynaecology ward of Princess Margaret Hospital in April 2014, with lower abdominal pain and recurrent retention of urine. Her pregnancy test was positive. Per-vaginal examination revealed a 4-cm firm, fixed, and wide-based vaginal mass with smooth wall over the upper anterior vagina. Bedside transabdominal ultrasonography confirmed a ...

Let (Bt )0≤t≤T be either a Bernoulli random walk or a Brownian motion with drift, and let Mt := max{Bs : 0 ≤ s ≤ t}, 0 ≤ t ≤ T . In this paper we solve the general optimal prediction problem sup0≤τ≤T E[f (MT −Bτ )], where the supremum is over all stopping times τ adapted to the natural filtration of (Bt ) and f is a nonincreasing convex function. The optimal stopping time τ∗ is shown to be of ‘...

Prominent ear is a relatively common deformity of the external ear, with an incidence of approximately 5% in Caucasians [1]. The main anatomical features of prominent ear are protrusion of the upper half of the helix with a wide conchoscaphal angle that results from failure of the antihelix to fold properly, in conjunction with a wide conchomastoid angle, deep conchal bowl, or absence of the he...

For many years there was a very common misbelief that having embedded mechanisms in hardware, constitute the optimal solution not only in the usage and the performance for the encryption algorithms, but for their security as well. The idea that lead to this common belief was that by this way an attacker could not tamper the encryption algorithms, specially regarding the asymmetric ones. M. Youn...
