We present one of the most efficient attacks against the combination generator. This attack is inherent to this system as its only assumption is that the filtering function has a good autocorrelation. This is usually the case if the system is designed to be resistant to other kinds of attacks. We use only classical tools, namely vectorial correlation, weight 4 multiples and Walsh transform.

An abstract framework for structured arguments is presented that instantiates Dung’s (1995) abstract argumentation frameworks. Arguments are defined as inference trees formed by applying two kinds of inference rules: strict and defeasible rules. This naturally leads to three ways of attacking an argument: attacking a premise, attacking a conclusion and attacking an inference. To resolve such at...

Previous research has found that reduced self-reassurance and heightened verbal 'self-attacking' of a sadistic and persecutory nature are both associated with greater subclinical paranoia. Whether these processes are also linked to clinical paranoia remains unclear. To investigate this further, we asked 15 people with persecutory delusions, 15 people with depression and 19 non-psychiatric contr...

Unconditional security of the BB84 quantum key distribution protocol has been proved by exploiting the fundamental laws of quantum mechanics, but the practical quantum key distribution system maybe hacked by considering the imperfect state preparation and measurement respectively. Until now, different attacking schemes have been proposed by utilizing imperfect devices, but the general security ...

Understanding the nutritional demands on serving military personnel is critical to inform training schedules and dietary provision. Troops deployed to Afghanistan face austere living and working environments. Observations from the military and those reported in the British and US media indicated possible physical degradation of personnel deployed to Afghanistan. Therefore, the present study aim...

ACIVIL CONFLICT IN AFGHANIstan for more than 2 decades has caused more than 3.5 million people to flee to neighboring countries, such as Pakistan and Iran, which are among the nations hosting the largest number of refugees in the world. Of the approximately 24 million people living in Afghanistan in March 2001, of whom more than 1 million are internally displaced, the World Food Programme estim...

HIV-1 Circulating Recombinant Form 35_AD (CRF35_AD) has an important position in the epidemiological profile of Afghanistan and Iran. Despite the presence of this clade in Afghanistan and Iran for over a decade, our understanding of its origin and dissemination patterns is limited. In this study, we performed a Bayesian phylogeographic analysis to reconstruct the spatio-temporal dispersion patt...

On the sixth anniversary of the US-led military invasion, Afghanistan is faced with its worst crisis since the ouster of the Taliban in 2001. There are increasing concerns, both internationally and domestically, that Afghanistan faces the distinct possibility of sliding back into instability and chaos. The country is challenged by a revitalized Taliban-led insurgency, record rise in drug produc...

BACKGROUND In previous studies an association between deployment to Iraq or Afghanistan and an overall increased risk for post-traumatic stress disorder (PTSD) in UK armed forces has not been found. The lack of a deployment effect might be explained by including, in the comparison group, personnel deployed on other operations or who have experienced traumatic stressors unrelated to deployment. ...
