Path length measuring is a relevant engineering problem. Leonardo Da Vinci designed for the military appropriate equipment, the podometer, to do so. Modern equipment such as step meters and map meters are quite similar to Da Vinci‟s design, despite geometrical statistical stereological methods based on theorems of Cauchy and Buffon that were potentially available for a long period of time for d...

Midbrain dopamine (DA) neurons in the substantia nigra pars compacta (SNc) and ventral tegmental area (VTA) exhibit somatodendritic release of DA. Previous studies indicate a difference between the Ca(2+) dependence of somatodendritic DA release in the SNc and that of axonal DA release in dorsal striatum. Here, we evaluated the Ca(2+) dependence of DA release in the VTA and nucleus accumbens (N...

BACKGROUND Attention-deficit/hyperactivity disorder (ADHD) predisposes to drug abuse (DA) and twin studies suggest shared genetic effects. We here seek to determine, using adoption and adoption-like samples, the magnitude of the cross-generational transmission from DA in parents to ADHD in their children and clarify the degree to which this arises from genetic v. rearing effects. METHOD We as...

Modern Standard Arabic (MSA) has a wealth of natural language processing (NLP) tools and resources. In comparison, resources for dialectal Arabic (DA), the unstandardized spoken varieties of Arabic, are still lacking. We present ELISSA, a machine translation (MT) system for DA to MSA. ELISSA employs a rule-based approach that relies on morphological analysis, transfer rules and dictionaries in ...

With the advancement of laparoscopic instruments and computer sciences, complex surgical procedures are expected to be safely performed by robot assisted telemanipulative laparoscopic surgery. The da Vinci system (Intuitive Surgical, Mountain View, CA, USA) became available at the many surgical fields. The wrist like movements of the instrument's tip, as well as 3-dimensional vision, could be e...

This study aimed to investigate the application of Group Dynamic Assessment (GDA) to writing accuracy of EFL learners and explore whether secondary interactants could benefit from interactions between mediator and primary interactants. The idea of implementing DA (Dynamic Assessment) in dyads seems unworkable since teachers are required to teach the whole class (Guk & Kellog, 2007). Moreover, L...

The mesolimbic dopamine (DA) system contains both D1-like and D2-like receptors, has been connected to control of locomotor behavior. An apparent role for D1 and D2 receptors throughout the mesolimbic system in the alteration of locomotor behavior has been demonstrated in pharmacological studies. The nucleus accumbens (NAc) is comprised of a core and a shell subregion, which is a component of t...

This paper presents a tool to aid in the construction of the data model for Data Warehouses, based on the corporative system data model and on user requirements. The purpose of the tool is to minimize difficulties and avoid conceptual errors in the creation of the dimensional model which may result from the designer’s lack of dimensional modeling skills. Resumo. Este artigo apresenta uma ferram...
