Ab initio calculation of the dynamical properties of PPP and PPV

, 2006
In this work, we have calculated the vibrational modes and frequencies of the crystalline PPP (in both the Pbam and Pnnm symmetries) and PPV (in the P21/c symmetry). Our results are in good agreement with the available experimental data.

Fibroblast Plasticity in Inflammation of the Barrier

Barrier Immunity, EarlyView.
Under inflammatory condition, fibroblasts in barrier tissues integrate inflammatory, senescent, and mechanical inputs. These pathways activate central signaling networks to drive fibroblast phenotypic transition, enabling cytokine production, immune cell recruitment, and extracellular matrix remodeling.

Exchange Rate Misalignment: A New Test of Long-Run PPP Based on Cross-Country Data (Subsequently published in "Applied Financial Economics", 16, 127-134, 2006. ) [PDF]

We formulate and implement a new empirical procedure to examine the validity of PPP in the long-run for 153 countries by using the familiar cross-country data set of Heston, Summers, and Aten (2002).
