Market makers have to continuously set bid and ask quotes for the stocks they have under consideration. Hence they face a complex optimization problem in which their return, based on the bid-ask spread they quote and the frequency they indeed provide liquidity, is challenged by the price risk they bear due to their inventory. In this paper, we provide optimal bid and ask quotes and closed-form ...
The mam plant communities of ultramafic (serpentine) outcrops of a Mediterranean area in central Italy are described and their successional pathway discussed. Four vegetation stages are distinguished: a) an endemic garigue stage, with high percentage of exposed rocky soil belonging to Armerio-Alyssetum bertolonii; b) a garigue stage similar to the previous one but with several Mediterranean eve...
The membrane attack complex (MAC) of the complement system induces a necrotic-type cell death. Earlier findings suggested that Bcl-2 protects cells from MAC-induced necrosis. Here we examined the involvement of Bid, a proapoptotic protein, in MAC-induced cytotoxicity. Bid knockout (Bid-/-) mouse embryonic fibroblasts (MEF) and primary fibroblasts were damaged by complement but to a significantl...
The Raobazhai ultramafic complex is located in the north of Dabie Mountains and composed spinel peridotites accompanied by a few lenticular mafic metamorphic rocks. are mostly harzburgite, along with minor dunite lherzolite. This study reports petrological, geochemical, Re-Os isotopic data chromite harzburgites from Raobazhai. major trace whole-rock geochemistry characteristics indicate that ro...
Ophiolitic complex of Sahneh could be considered as part of ophiolite sequences in the Zagros Suture Zone.This complex is a part of 3000 km belt, which is started from Syria after crossing south Turkey and Zagros leading to Oman. The studied ophiolitic complex is curvature in shape which is situated in south of Sahneh. No complete ophiolite sequence were seen in this complex. In general, t...
introduction worldwide, ni-cu and pge magmatic sulfide deposits are confined to the lower parts of stratiform mafic and ultramafic complexes. however, ophiolite mafic and ultramafic complexes have been rarely explored for sulfide deposits despite the fact that they have been extensively explored and exploited for chromite. sulfide saturation during magmatic evolution is necessary for sulfide mi...
1 Geological carbon capture and storage in mafic and ultramafic rocks – Muscat, 2011
The BH3-only protein Bid plays a key role in the induction of mitochondrial apoptosis, but its mechanism of action is still not completely understood. Here we studied the two main activation events of Bid: Caspase-8 cleavage and interaction with the membrane bilayer. We found a striking reversible behaviour of the dissociation-association events between the Bid fragments p15 and p7. Caspase-8 c...
