Estimate of Saturation Pressures of Crude Oil by Using Ensemble-Smoother-Assisted Equation of State
(American Chemical Society, 2018-11-20)The equation of state (EOS) has been extensively used to evaluate the saturation pressures of petroleum fluids. However, the accurate determination of empirical parameters in the EOS is challenging and time-consuming, ... -
Quantification of Viscosity for Solvents−Heavy Oil/Bitumen Systems in the Presence of Water at High Pressures and Elevated Temperatures
(American Chemical Society, 2018-12-18)In this study, a new and pragmatic methodology has been developed to accurately predict the viscosity for light solvents (i.e., methane, ethane, propane, n-butane, n-pentane, N2, and CO2)–heavy oil/bitumen/water systems ... -
A Review of Brittleness Index Correlations for Unconventional Tight and Ultra-Tight Reservoirs
(MDPI, 2019-07-19)Brittleness is a key parameter in the development of the unconventional shale and tight carbonate reservoirs as it plays a role in the design of the hydraulic fractures as well as the selection of the sweet-spot locations ... -
Impact of Heterogeneity on the Transient Gas Flow Process in Tight Rock
(MDPI, 2019-09-17)There exits a great challenge to evaluate the flow properties of tight porous media even at the core scale. A pulse-decay experiment is routinely used to measure the petrophysical properties of tight cores including ... -
Role of ALDH1A1 and HTRA2 expression in CCL2/CCR2-mediated breast cancer cell growth and invasion
(The Company of Biologists, 2019-06-28)Chemokines mediate immune cell trafficking during tissue development, wound healing and infection. The chemokine CCL2 is best known to regulate macrophage recruitment during wound healing, infection and inflammatory diseases. ... -

Multivalent antigen arrays exhibit high avidity binding and modulation of B cell receptor-mediated signaling to drive efficacy against experimental autoimmune encephalomyelitis
(American Chemical Society, 2017-05-05)A pressing need exists for antigen-specific immunotherapies (ASIT) that induce selective tolerance in autoimmune disease while avoiding deleterious global immunosuppression. Multivalent soluble antigen arrays (SAgAPLP:LABL), ... -
Acute B-Cell Inhibition by Soluble Antigen Arrays Is Valency-Dependent and Predicts Immunomodulation in Splenocytes
(American Chemical Society, 2019-04-17)Antigen valency plays a fundamental role in directing the nature of an immune response to be stimulatory or tolerogenic. Soluble Antigen Arrays (SAgAs) are an antigen-specific immunotherapy that combats autoimmunity through ... -
