We study how a multisided platform’s decision to certify subset of its complementors affects those and ultimately the platform itself. Kiva, microfinance platform, introduced social performance badging program in December 2011. The appears have been beneficial Kiva—it led more borrowers, lenders, total funding, amount funding per lender. To better understand mechanisms behind this increase, we ...

OBJECTIVE The aim of this study was to investigate the roles of prostaglandins (PGs) in the anteroventral third ventricular region (AV 3V), a cerebral site for cardiovascular homeostasis, in hypovolemia-induced vasopressin (AVP) secretion. METHODS We infused meclofenamate (78. 3 nmol in 1 microl), a PG synthesis inhibitor, or PGE2 (7.1 nmol in 0.5 microl) into the AV 3V of conscious rats, exa...

SUMMARY This is the second part of the numerical investigation on a low emissions staged turbine combustor (STC) using a modified version of the KIVA-II code. The main focus of this study is the numerical analysis of the reacting fluid flow and heat transfer inside the quick-quench/lean-combustion (QQ/LC) zones. In the QQ zone, cool dilution air was injected into the hot mixture through eight 4...

Injections of the melanocortin 3/4 receptor (MCR) agonist melanotan II (MTII) to a variety of brain structures produces anorexia, suggesting distributed brain MCR control of food intake. We performed a detailed analysis of feeding behavior (licking microstructure analysis) after a range of MTII doses (0.005 nM to 1 nM) was targeted to the forebrain (third ventricle, 3V) or hindbrain (fourth ven...

Cumulants of the three state Potts model and of nonequilibrium models with C 3v symmetry Abstract The critical behavior of two-dimensional stochastic lattice gas models with C 3v symmetry is analyzed. We study the cumulants of the order parameter for the three state (equilibrium) Potts model and for two irreversible models whose dynamic rules are invariant under the symmetry operations of the p...
