cytomegalovirus is the most common viral infection after kidney transplantation. clinical presentations of cytomegalovirus infection range from asymptomatic infection to organ-specific involvement. most symptomatic infections manifest as fever and cytopenia. the gastrointestinal tract is the most common site of tissue-invasive infection, often presenting as diarrhea or gastrointestinal bleeding...

BACKGROUND In Australia, a Goods and Services Tax (GST) introduced in 2000 led to a decline in the price of ready-to-drink (RTD) beverages relative to other alcohol products. The 2008 RTD ("alcopops") tax increased RTD prices. The objective of this study was to estimate the change in incidence of Emergency Department (ED) presentations for acute alcohol problems associated with each tax. METH...

In a free recall experiment, total study time per item (2, 4, or 6 sec between subjects) was crossed, with number of item presentations (1 vs. 2, within subjects). Consequently, each subject studied two lists in which each item was presented once for durations of 2, 4, or 6 sec (the prolonged lists), and two lists in which each item was presented twice, spaced, for durations of 1, 2, or 3 sec, ...

Previous studies on discourse have employed a self-paced sentence-bysentence paradigm to present text and record reading times. However, presenting discourse this way does not mirror real-world reading conditions; for example, this paradigm prevents regressions to earlier portions of the text. The purpose of the present study is to investigate the ecological validity of self-paced sentence-byse...

The present study investigated whether reactivity to nicotine-related cues would attenuate across four experimental sessions held 1 week apart. Participants were nineteen non-treatment seeking, nicotine-dependent males. Cue reactivity sessions were performed in an outpatient research center using in vivo cues consisting of standardized smoking-related paraphernalia (e.g., cigarettes) and neutra...

In the blocking paradigm, subjects receive reinforced presentations of a compound, AX, after reinforced presentations of A alone. Following this training, responding to X is often diminished relative to a control group, which did not receive the prior training with A. Standard associative theories of learning such as the Rescorla-Wagner model (Rescorla & Wagner, 1972) explain this effect by ass...

This study tested whether a general increase in emotional arousal is a sufficient determinant for the evocation of the N150, a negative wave in amygdalar Auditory Evoked Potentials (AEPs). Rats received one of three conditioning protocols: either conditioned stimulus (CS) presentations alone (Control) CS-shock pairings (Paired) or unpaired presentations of the CS and shock (Unpaired). Amygdalar...

We study the implications of model completeness a theory for effectiveness presentations models that theory. It is immediate computable $$\mathcal {A}$$ computably enumerable, complete theory, entire elementary diagram $$E(\mathcal {A})$$ must be decidable. prove indeed c.e. T if and only there uniform procedure succeeds in deciding from atomic $$\varDelta (\mathcal all countable T. Moreover, e...

The algorithm of the successive derivatives introduced in [5] was implemented in [7], [8]. This algorithm is based on the existence of a decomposition of 1-forms associated to the relative cohomology of the Hamiltonian function which is perturbed. We explain here how the first step of this algorithm gives also the first derivative of the period function. This includes, for instance, new present...

One way to increase happiness is to increase the objective levels of external outcomes; another is to improve the presentation and choices among external outcomes without increasing their objective levels. Economists focus on the first method. We advocate the second, which we call hedonomics. Hedonomics studies (a) relationships between presentations (how a given set of out-comes are arranged a...
