Fault sensitivity analysis (FSA) is a side-channel attack method that injects faults to cryptographic circuits through clock glitching and applies statistical analysis to deduce sensitive data such as the cryptographic key. It exploits the correlation between the circuit’s signal path delays and sensitive data. A countermeasure, in this case, is an alternative implementation of the circuit wher...

Vigilance tasks, from driving to surveillance to security remain important and frequent tasks for the US Army. Yet the difficulty users have sustaining vigilance is well known. Augmented cognition offers new methods for supporting sustained vigilance via a closed-loop attention management system (CLAM). A CLAM system monitors operators’ psychophysiology for signs of inattention and then trigger...

Whole body vibration with resistive exercise is a promising countermeasure against some weightlessness-induced dysfunctions. Our objective was to study whether the combination of low-magnitude whole body vibration with a resistive exercise can prevent the cardiovascular deconditioning induced by a nonstrict 60-day head-down bed rest (Earth Star International Bed Rest Experiment Project). Fourte...

Inserting random delays in cryptographic implementations is often used as a countermeasure against side-channel attacks. Most previous works on the topic focus on improving the statistical distribution of these delays. For example, efficient random delay generation algorithms have been proposed at CHES 2009/2010. These solutions increase security against attacks that solve the lack of synchroni...

original article   shift work is a common work schedule that has several inappropriate consequences, the most important of which is fatigue. the aim of this study was to invest gate the impact of the shift length on the occupatio al fatigue of operators in filling stations. this cross-sectional study was carried out on operators of the filling station in national iranian oil products distributi...

background: cancer can lead to fatigue and the manifestation of psychological symptoms in patients, including depression, anxiety, and stress. objectives: the aim of this study was to investigate the relationship between fatigue and psychological symptoms in patients with gastrointestinal cancer. materials and methods: the study had a descriptive, cross-sectional design. we assessed levels of f...

fatigue behavior of a vanadium microalloy steel has been studied in this research. here, microstructure constituents were considered which essentially are dependent on the heat treatment conditions. the results of high cycle fatigue tests revealed that heat treatment procedure and cooling rates have significant effects on fatigue properties. optimal heat treatment cycle of the microalloyed stee...

Recently, China has a more prominent trend of domestic price rise, which has obviously influenced public’s daily life and corporate production and operation. If we don’t take effective measures to deal with price trend, it will lead to further strengthened inflation expectation and deteriorate market economy order. Business community is actively seeking countermeasures to deal with the impact o...

Chen et al. in 2004 proposed a new hierarchy structure, called the enhanced pyramid network (EPM, for short), by replacing each mesh in a pyramid network (PM, for short) with a torus. Recently, some topological properties and communication on the EPMs have been investigated or derived. Their results have revealed that an EPM is an attractive alternative to a PM. This study investigates the node...
