Introduction Amnion rupture in early pregnancy results in severe anomalies such as anencephaly, encephalocoele, exencephaly, acrania, facial clefts and absence of limbs (1,2). Most affected fetuses abort in the second trimester, are stillborn or die soon after birth (1,3).We report an infant with amnion rupture sequence, who survived for 9 weeks after birth. A Medline search failed to reveal do...

Making critical sections abortable is a promising approach to reducing priority inversions. To improve the schedulability of a system using abortable critical sections, the maximum number of abortions should be decreased. In this paper, we propose a real-time synchronization protocol named the ceiling abort protocol (CAP) which introduces a new priority-based abort scheme to the priority ceilin...

In this paper we apply impossible differential attacks to reduced round AES. Using various techniques, including the early abort approach and key schedule considerations, we significantly improve previously known attacks due to Bahrak-Aref and Phan. The improvement of these attacks leads to the best known impossible differential attacks on 7-round AES-128 and AES-192, as well as to the best kno...

This paper investigates the time-complexity of the non-blocking atomic commit (NBAC) problem in a synchronous distributed model where t out of n processes may fail by crashing. We exhibit for t ≥ 3 an inherent trade-off between the fast abort property of NBAC, i.e., aborting a transaction as soon as possible if some process votes “no,” and the fast commit property, i.e., committing a transactio...
