This paper discusses cake-cutting protocols when the cake is a heterogeneous good that is represented by an interval in the real line. We propose a new desirable property, the meta-envy-freeness of cake-cutting, which has not been formally considered before. Though envy-freeness was considered to be one of the most important desirable properties, envy-freeness does not prevent envy about role a...

To explore the use of Caenorhabditis elegans and related nematodes for studying behavioral evolution, we conducted a comparative study of pharyngeal behaviors and neuronal regulation in free-living soil nematodes. The pharynx is divided into three parts: corpus, isthmus and terminal bulb, and pharyngeal behaviors consist of stereotyped patterns of two motions: pumping and peristalsis. Based on ...

abstract nitrogen is a key nutrient in plant growth and it is necessary for amino acid synthesis. sulfur has very important role in the biosynthesis of the alliums flavor and pungency precursors and potassium improve crop yield and quality. in order to study the effect of ammonium nitrate and potassium sulfate on concentration some of the mineral elements in onion (allium cepa l. azar shahr cv....

Lateral inhibition in the olfactory bulb is mediated by circuits that involve reciprocal dendrodendritic connections between mitral and granule cells. Because of the properties of these connections and also because odor stimuli are not represented in an obviously topographic fashion, questions have been raised about whether the function of local inhibition in the olfactory bulb can be compared ...

in this case report, a 36 year old female at 40 weeks' gestation is presented in whom large bilateral vestibular bulb masses were found on pelvic examination. the size of the masses was such as to cause concern that they may pose an impediment to normal parturition. our pathological findings, management and results are presented.

to determine the threshold of photoperiodism and culmulative thermal time related to bulbing and growth analysis of safid behbehan, ghermez iranshahr and primavera onion cultivars an experiment was conducted at behbahan agricultural research station for a year (2006-2007) based on a randomized complete block design of four replications. seeds were sown in nursery in late october and seedlings t...

We examine the history of cake cutting mechanisms and discuss the efficiency of their allocations. In the case of piecewise uniform preferences, we define a game that in the presence of strategic agents has equilibria that are not dominated by the allocations of any mechanism. We identify that the equilibria of this game coincide with the allocations of an existing cake cutting mechanism.
