BACKGROUND Multiple factors can account for surgical complexity during laparoscopic partial nephrectomy (LPN); severe adhesion of perirenal fat (PRF) is a crucial one. Consequent renal decapsulation can deem renorrhaphy a very challenging task. We propose a novel technique (synthetic renal capsule tailoring [SYRCT]) to facilitate renorrhaphy in decapsulated kidneys and suggest early decapsulati...

in the present study, sulfuric acid was used for artemia cysts decapsulation. cysts of artemia franciscana were hatched out in regular manner or following hypochlorite or acid decapsulation. two acid concentrations (1 and 5%), three acid immersion times (10, 30 and 50 min) were used and hatching rates were recorded after 15, 18 and 24 h incubation. hatching rates increased but hatching time dec...

While the hybrid public key encryption scheme of Kurosawa and Desmedt (CRYPTO 2004) is provably secure against chosen ciphertext attacks (namely, IND-CCA-secure), its associated key encapsulation mechanism (KEM) is widely known as not IND-CCA-secure. In this paper, we present a direct proof of IND-CCA security thanks to a simple twist on the Kurosawa-Desmedt KEM. Our KEM beats the standardized ...

We propose a methodology to construct verifiable random functions from a class of identity based key encapsulation mechanisms (IB-KEM) that we call VRF suitable. Informally, an IB-KEM is VRF suitable if it provides what we call unique decryption (i.e. given a ciphertext C produced with respect to an identity ID, all the secret keys corresponding to identity ID ′, decrypt to the same value, even...

Strictly enforced encapsulation is a key concept for modular software designs. However, in many situations like unanticipated reuse, productivity can be raised by a more flexible approach to encapsulation. Also the discussion about the role of “obliviousness” in aspect-oriented programming is one instance of a general conflict between strictness and flexibility. Here, different technologies tak...
