Pavlovian conditioning research has shown that unconditioned responses (UCR) to aversive unconditioned stimuli (UCS) are reduced when a UCS is predictable. This effect is known as UCR diminution. In the present study, we examined UCR diminution in the functional magnetic resonance imaging (fMRI) signal by varying the rate at which a neutral conditioned stimulus (CS) was paired with an aversive ...

The focus of this paper is to introduce a theory based on a wide-spreading model of Use Cases (UCs). The pervasive benefits of UCs in the computer systems and software’s developments have motivated the UCs formalization needing. Also, the definition of UCs through Use Case Description Markup Language (UCDML) is enabled the XML technology explotation in order to suggest the powerful ways for the...

This paper presents Fuzzy-UCS, a Michigan-style Learning Fuzzy-Classifier System designed for supervised learning tasks. FuzzyUCS combines the generalization capabilities of UCS with the good interpretability of fuzzy rules to evolve highly accurate and understandable rule sets. Fuzzy-UCS is tested on a large collection of real-world problems, and compared to UCS and three highly-used machine l...

The potency of an unconditioned stimulus (UCS) can impact the degree of fear learning. One of the most common and effective UCSs is an electric shock, which is inappropriate for certain populations (e.g., children). To address this need, a novel fear learning paradigm was recently developed that uses a fearful female face and scream as the UCS. The present study directly compared the efficacy o...

BACKGROUND This pilot study compared the effects of lexical-semantic stimulation through telecommunication technology (LSS-tele) with in-person LSS (LSS-direct) and unstructured cognitive treatment (UCS) in patients with early Alzheimer's disease. METHODS Twenty-seven patients with Alzheimer's disease in the very early stage (Mini-Mental State Examination [MMSE] >26/30) were divided into thre...

Partial replacement of cement by silica fume in concrete provides advantages such as mitigation the impact on environment carbon dioxide emitted during production, recycling industrial by-products and improvement strength durability. The optimization mixture (SFC) requires trade-off among multiple objectives (strength, cost embodied CO2) consideration a large number variables under highly nonli...

Pneumocystis carinii are coated by abundant surface proteins, named MSGs for major surface glycoproteins, that undergo antigenic variation. There are many MSG genes on the chromosomes but the MSG expression site is restricted to a unique site called type-I UCS, and silent MSG genes can be translocated to the expression site by DNA recombination. We have reported previously the existence of alte...
