Not so different from non-traders

Not so Non-renormalizable Gravity

We review recent progress with the understanding of quantum fields, including ideas [1] how gravity might turn out to be a renormalizable theory after all.

So What Orders Do Informed Traders Use ? ∗

We present a simple, Glosten-Milgrom type equilibrium model to analyze the decision of informed traders on whether to use limit or market orders. We show that even after incorporating an order’s price impact, not only may informed traders prefer to use limit orders, but the probability that they submit limit orders can be so high that limit orders convey more information than market orders. We ...

Tobacco and obesity epidemics: not so different after all?

Scaling of growth: plants and animals are not so different.

T relationship of body size to the anatomical, physiological, behavioral, and ecological characteristics of animals has long been a focus of interest in zoology. As one considers animal species of different sizes, regular, predictable changes are seen in the relative proportions of the body’s organs and the relative rates of physiological processes such as metabolism and growth. Students of zoo...

Lysosomal and vacuolar sorting: not so different after all!

Soluble hydrolases represent the main proteins of lysosomes and vacuoles and are essential to sustain the lytic properties of these organelles typical for the eukaryotic organisms. The sorting of these proteins from ER residents and secreted proteins is controlled by highly specific receptors to avoid mislocalization and subsequent cellular damage. After binding their soluble cargo in the early...
