We deal with two classes of locally compact sober spaces, namely, the class of locally spectral coherent spaces and the class of spaces in which every point has a closed spectral neighborhood (CSN-spaces, for short). We prove that locally spectral coherent spaces are precisely the coherent sober spaces with a basis of compact open sets. We also prove that CSN-spaces are exactly the locally spec...

SOBER-128 is a stream cipher designed by Rose and Hawkes in 2003. It can be also used for generating Message Authentication Codes (MACs) and an authenticated encryption. The developers claimed that it is difficult to forge MACs generated by both functions of SOBER128, though, the security assumption in the proposal paper is not realistic in some instances. In this paper, we examine the security...

In this study, it is aimed to compare the executive functioning and problem solving styles of relapsed alcoholdependent and protracted sober patients and to evaluate the potential clinical factors that act on the duration of sobriety. Fifty-six male patients meeting the DSM-IV alcohol dependence criteria included in the study. All patients were in sobriety period, classified as 32 of them in ac...

Some researchers have found that day-of-injury alcohol intoxication is associated with worse outcome following traumatic brain injury (TBI). The purpose of this study is to examine the effects of day-of-injury intoxication on the acute neuropsychological outcome from TBI. Participants were 36 patients with TBI (18 sober, 18 intoxicated) matched on injury severity characteristics and demographic...

The present research examined whether the production of a narrative containing self-redemption (wherein the narrator describes a positive personality change following a negative experience) predicts positive behavioral change. In Study 1, we compared the narratives of alcoholics who had maintained their sobriety for over 4 years with those of alcoholics who had been sober 6 months or less. When...

We analyze a dynamic model of international environmental agreements where countries cannot make long-term commitments or use sanctions rewards to induce cooperation. The equilibrium is Markov chain, not particular coalition. A large and effective coalition an absorbing state, reached after random succession short-lived ineffective coalitions. Reaching such requires that the endogenous probabil...
