Abstract Dual particle imaging, in which both neutrons and gamma-rays the environment can be individually characterized, is particularly attractive for monitoring mixed radiation emitters such as special nuclear materials (SNM). Effective SNM localization detection benefits from high instrument sensitivity so that real-time imaging or with a limited number of acquired events enabled. For portab...

OBJECTIVE To investigate lifespan age differences in neuronal mechanisms of visual coding in the context of perceptual discrimination. METHODS We recorded EEG from 17 children (10-12 years), 16 younger adults (20-26 years), and 17 older adults (70-76 years) during a simple choice-reaction task requiring discrimination of squares and circles of different sizes. We examined age-group difference...

The uranium concentration in 59 samples of bottled and tap water, mainly from northern Italy, was measured by different techniques. Results obtained by inductively coupled plasma mass spectrometry (ICP-MS), semiconductor alpha spectrometry and low level liquid scintillation counting with alpha/beta discrimination (LSC) have been compared. High resolution gamma spectrometry and semiconductor alp...

We studied the application of the Pseudo-Zernike features as image parameters (instead of the Hillas parameters) for the discrimination between the images produced by atmospheric electromagnetic showers caused by gamma-rays and the ones produced by atmospheric electromagnetic showers caused by hadrons in the MAGIC Experiment. We used a Support Vector Machine as classification algorithm with the...

Young infants discriminate phonetically relevant speech contrasts in a universal manner, that is, similarly across languages. This ability fades by 12 months of age as the brain builds language-specific phonemic maps and increasingly responds preferentially to the infant's native language. However, the neural mechanisms that underlie the development of infant preference for native over non-nati...

Musical priming research has reported that sensory consonance/dissonance judgements for a target chord were faster when targets were musically related to a musical prime context. The present study extended this context effect to a timbre discrimination task. This new task allowed us to investigate whether musical priming results from congruency effects similar to those reported in other domains...

the dependence of the lateral distribution of cherenkov light in simulated extensive air showers to the energy and the mass of the primary cosmic rays has been studied. it has been shown that a previous claim about mass independent proportionality of shower energy to the total cherenkov photon number is not valid in energies below eeas ~ 1014 ev. we have found that the core distance of the so c...

Discriminant function analysis was used to determine the optimum combination of haematological and biochemical tests which gave the best discrimination between hospital patients with high and low alcohol intakes. We studied 265 patients with alcohol-related disease, 133 gastroenterology outpatients drinking less than 20 g of alcohol per day, and 104 patients with a variety of non-alcoholic live...

The present experiment investigated the effects of muscimol injections into the rat dorsal anterior cingulate on the acquisition and reversal learning of a 4-choice odor discrimination. Long-Evans rats were trained to dig in cups that contained distinct odors. In the odor discrimination, one odor cup contained a cereal reinforcement in acquisition whereas a different odor cup contained a cereal...
