Natural isolates of C. elegans differ in their sensitivity to pheromones that inhibit exploratory behavior. Previous studies identified a QTL for pheromone sensitivity that includes alternative alleles of srx-43, a chemoreceptor that inhibits exploration through its activity in ASI sensory neurons. Here we show that the QTL is multigenic and includes alternative alleles of srx-44, a second chem...

Deaton and Lubotsky (2003) found that the robust positive relationship across American cities between mortality and income inequality became small, insignificant, and/or non-robust once they controlled for the fraction of each city's population that is black. Ash and Robinson (Ash, M., & Robinson D. Inequality, race, and mortality in US cities: a political and econometric review. Social Science...

In multiobjective optimization problems, the identified Pareto Frontiers and Sets often contain too many solutions, which make it difficult for the decision maker to select a preferred alternative. To facilitate the selection task, decision making support tools can be used in different instances of the multiobjective optimization search to introduce preferences on the objectives or to give a co...

When conducting electronic auctions, sellers obviously wish to maximize their revenue and one tool economic theory suggests they might use is an entry fee. By charging bidders a certain amount for entering an auction, the seller can theoretically extract more surplus from those bidders that choose to enter the auction. The problem a seller faces is that the use of an entry fee might discourage ...

Nowadays, huge tendency to fashion and consumerism could be assumed as the origin of identitycrisis among women and in their houses. This phenomenon is like a veil between man and the fact of his human being. Given that the physical properties of man-made environments (house) are influenced by human properties and, in return, have an important role in giving identity to their audience, identifi...

The importance of small urban parks (SUP) in mega cities has been accepted as an essential component of urban lung and restorative settings. As urban population in the world increases and the cost of maintaining large parks escalates, urban authorities are shifting their attention to creating and maintaining smaller urban parks. However, SUP may present a different ambience due to their locatio...

subchondral insufficiency fracture of the femoral head (siffh) is characterized by acute onset hip pain without overt trauma. it appears as a low intensity band with bone marrow edema on t1-weighted mri. the most common course of treatment is protected weight bearing for a period of several weeks. total hip arthroplasty (tha) has been commonly used if the patient does not respond to the initial...

Ideally, when selecting a system design or re-design, the selected option should balance workload and performance. However, previous research suggests that the relationship between workload and performance is nonlinear, thus achieving one, does not imply achieving the other. To ensure that a system will meet performance and workload goals, system designers should investigate the expected worklo...
