In 1972, Crawford and Sinclair published evidence that AA and DHA were independent determinants of brain growth and evolution [Crawford and Sinclair 1972; Broadhurst et al., 2002; Enard et al., 2002; Pennisi 2002]. Deficiency studies in rodents [Sinclair and Crawford 1972; Benolken et al., 1973; Galli and Socini, 1983; Weisinger et al., 1999; Catalan et al., 2002], chickens [Budowski et al., 19...

A multisensor fusion Student's $t$ filter is proposed for time-series recursive estimation in the presence of heavy-tailed process and measurement noises. It extends single-sensor Kalman to setup based on suboptimal arithmetic average (...

We document that firms’ management of accounting earnings increased steadily from 1987 until the passage of the Sarbanes Oxley Act (SOX), with a significant increase during the period prior to SOX, followed by a significant decline after passage of SOX. However, the increase in earnings management preceding SOX was primarily in poorly performing industries. We also show that the informativeness...

We review the relation between the matrix model and Liouville approaches to two-dimensional gravity as elaborated by Moore, Seiberg and Staudacher. Then, based on the supersymmetric Liouville formulation and the discrete eigenvalue model proposed by Alvarez-Gaumé, Itoyama, Mañes and Zadra, we extend the previous relation to the supersymmetric case. The minisuperspace approximation for the super...

Clausal forms of logics are of great relevance in Artificial Intelligence, because they couple a high expressivity with a low complexity of reasoning problems. They have been studied for a wide range of classical, modal and temporal logics to obtain tractable fragments of intractable formalisms. In this paper we show that such restrictions can be exploited to lower the complexity of interval te...

Cerebral accumulation of amyloid A protein (AA) is characteristic of Alzheimer disease (AD). AA can be detected in cerebrospinal fluid and in plasma. Although plasma AA has been proposed as a marker of risk of AD, it is unknown how plasma levels relate to neuropathologic levels. We compared plasma levels of AA40 and AA42 obtained during life with biochemical and pathologic levels in frontal and...
