Differential power analysis (DPA) has become a real-world threat to the security of cryptographic hardware devices such as smart-cards. By using cheap and readily available equipment, attacks can easily compromise algorithms running on these devices in a non-invasive manner. Adding non-determinism to the execution of cryptographic algorithms has been proposed as a defence against these attacks....

Abstract The present study explores the impact of corpus-based collocation instruction on intermediate Iranian EFL learners' writing ability. For this study, 84 Iranian learners, studying English as a foreign language in Bayan Institute, Iran, were selected and were randomly divided into two groups, experimental and control. Conventional methods of writing instruction were taught to the control...

We present an approach to non-uniform complexity in which singlepass instruction sequences play a key part, and answer various questions that arise from this approach. We introduce several kinds of non-uniform complexity classes. One kind includes a counterpart of the well-known non-uniform complexity class P/poly and another kind includes a counterpart of the well-known non-uniform complexity ...

The paper examines a simple conceptual modification of the operation unit of a RISC processor. We propose to substitute a part of the conventional general purpose register file by a shift register for all operation results. The presented approach allows to reduce the instruction size for a great deal of instructions and so the instruction stream, and it is also a promising approach to make the ...

the article takes its cue from models of quantitative research applied to complementary/alternative medicine (cam) and pinpoints some innovative features in the case at issue (portugal). it goes on to outline new research scenarios moving beyond the either biomedical or cam framework.

originating from vygotsky’s sociocultural theory, dynamic assessment (da) proposes a novel approach to second language acquisition (sla) research according to which a dialectical relationship is envisaged between instruction and assessment. although da has been applied to some areas of sla, there are areas, such as interlanguage pragmatics (ilp), that have been neglected.  to address the issue,...

The present study aimed to examine any possible relevance of perfectionism as a personal trait variable, in moderating the effectiveness of meta-cognitive instruction on bottom-up and top-down sub-processes of listening comprehension with a sample of EFL learners in Iranian context. To this end, 94 female EFL learners were selected from among 136 EFL learners at Andisheh Language Institute in M...

Anesthesiologists often encounter unexpected situations that may result in fatal consequences if not managed promptly and prudently. Management of a difficult airway is a primary consideration for any anesthesiologist. Even in the most experienced hands, an emergency situation may arise because of either limited time or limited resources. Here we present a case report in which a difficult airwa...
