TWINE is a recent lightweight block cipher based on a Feistel structure. We rst present two new attacks on TWINE-128 reduced to 25 rounds that have a slightly higher overall complexity than the 25round attack presented by Wang and Wu at ACISP 2014, but a lower data complexity. Then, we introduce alternative representations of both the round function of this block cipher and of a sequence of 4 r...

hepatitis c virus (hcv) encodes two envelope glycoproteins, e1 and e2. our previous work selected a specific aptamer ze2, which could bind to e2 with high affinity, with a great potential for developing new molecular probes as an early diagnostic reagents or therapeutic drugs targeting hcv. in this study, the binding sites between e2 and aptamer ze2 were further explored. e2 was truncated to 15...

as an application of hirota bilinear method, perturbation expansion truncated at different levels is used to obtain exact soliton solutions to (2+1)-dimensional nonlinear evolution equation in much simpler way in comparison to other existing methods. we have derived bilinear form of nonlinear evolution equation and using this bilinear form, bilinear backlund transformations and construction of ...

We show key recovery attacks on generic balanced Feistel ciphers. The analysis is based on the meet-in-the-middle technique and exploits truncated differentials that are present in the ciphers due to the Feistel construction. Depending on the type of round function, we differentiate and show attacks on two types of Feistels. For the first type, which is the most general Feistel, we show a 5-rou...

background in spite of dozens of clinical trials to establish effective therapeutic and/or preventive vaccine to resolve hcv infection, no real vaccine has been proved to date. genetic vaccines based on replication-defective adenoviruses have proved to elicit strong and long lasting t-cell responses against a number of viral antigens and are even currently being used for vaccine trials in human...
