Reduced vasorin enhances angiotensin II signaling within the aging arterial wall
( Impact Journals , 2018 , Article)The glycosylated protein vasorin physically interacts with the transforming growth factor-beta1 (TGF-β1) and functionally attenuates its fibrogenic signaling in the vascular smooth muscle cells (VSMCs) of the arterial wall. ... -
Reduced-complexity sparsity-aware joint phase noise mitigation and channel equalization in OFDM receivers
( Elsevier B.V. , 2018 , Article)A major performance and complexity limitation in direct-conversion broadband wireless transceivers is the phase noise (PN) resulting from the inevitable imperfections in the fabrication process of the crystal oscillator. ... -
Reducing data center energy consumption through peak shaving and locked-in energy avoidance
( Institute of Electrical and Electronics Engineers Inc. , 2017 , Article)The grid company enforces high penalties for the peak power demands of cloud data centers. These penalties result in high electricity bills that can be avoided by relying on the servers' uninterruptible power supply (UPS) ... -
Reducing energy consumption of CO2 desorption in CO2-loaded aqueous amine solution using Al2O3/HZSM-5 bifunctional catalysts
( Elsevier Ltd , 2018 , Article)The aim of this work is to find a potential way for great decrease in CO2 capture energy requirement. Here, for the first time, a series of bifunctional Al2O3/HZSM-5 catalysts (Al-ZSM) were prepared by the combined ... -
Reducing flux decline and fouling of direct contact membrane distillation by utilizing thermal brine from MSF desalination plant
( Elsevier B.V. , 2016 , Article)Fouling and scaling is one of the major challenges in membrane distillation process. This study investigates the utilizing of thermal rejected brine produced from multi-stage flash distillation (MSF) to minimize fouling ... -
Reducing health provider stereotypes through undergraduate interprofessional education
( Elsevier , 2022 , Article)ObjectiveStereotypes among health professionals can jeopardize the delivery of collaborative healthcare and the achievement of positive patient outcomes. However, interprofessional education (IPE) can promote early ... -
Reducing material convergence in disaster environments: The potential of trusted change agents
( Elsevier , 2022 , Article)The research in this paper seeks to advance the effective management of one of the most intractable aspects of disaster response phenomena: material convergence-the sudden and mostly uncoordinated arrival of physical ... -
Reducing railway-induced ground-borne vibration by using open trenches and soft-filled barriers
( Elsevier Ltd , 2016 , Article)A trench can act as a barrier to ground vibration and is a potential mitigation measure for low frequency vibration induced by surface railways. However, to be effective at very low frequencies the depth required becomes ... -
