Activation and stabilization of gallium arsenide anode in an aqueous photoelectrochemical cell
( Elsevier , 2003 , Article)The formation of a porous layer on the surface of gallium arsenide anode, n-GaAs, increases photogenerated currents significantly. This layer was formed as a result of an anodic polarization of illuminated n-GaAs in acidified ... -
Activation Dynamics and Immunoglobulin Evolution of Pre-existing and Newly Generated Human Memory B cell Responses to Influenza Hemagglutinin.
( Elsevier , 2019 , Article)Vaccine-induced memory B cell responses to evolving viruses like influenza A involve activation of pre-existing immunity and generation of new responses. To define the contribution of these two types of responses, we ... -
Activation of K7 channels with the anticonvulsant retigabine alleviates neuropathic pain behaviour in the streptozotocin rat model of diabetic neuropathy.
( Taylor & Francis (Routledge) , 2019 , Article)Diabetic peripheral neuropathy (DPN) is the most incapacitating complication of diabetes mellitus. Up to 50% of patients with DPN develop peripheral neuropathic pain (PNP). The underlying ionic and molecular mechanisms of ... -
Activation of kaolin with minimum solvent consumption by microwave heating
( Mineralogical Society , 2014 , Article)A kaolin clay was activated with 1.0 M H2SO4 solution at minimum liquid to solid ratio (L/S) using microwave heating. The optimum experimental conditions for activation were L/S ratio 3.0 mL 1 M H2SO4 per gram kaolin, ... -
Activation of pruritogenic TGR5, MRGPRA3, and MRGPRC11 on colon-innervating afferents induces visceral hypersensitivity
( American Society for Clinical Investigation , 2019 , Article)Itch induces scratching that removes irritants from the skin, whereas pain initiates withdrawal or avoidance of tissue damage. While pain arises from both the skin and viscera, we investigated whether pruritogenic irritant ... -
Activation of the pro-oxidant PKC?IIp66Shc Signaling pathway contributes to pericyte dysfunction in skeletal muscles of patients with diabetes with critical limb Ischemia
( American Diabetes Association Inc. , 2016 , Article)Critical limb ischemia (CLI), foot ulcers, former amputation, and impaired regeneration are independent risk factors for limb amputation in subjects with diabetes. The present work investigates whether and by which mechanism ... -
Activation of the Pro-Oxidant PKCβII-p66Shc Signaling Pathway Contributes to Pericyte Dysfunction in Skeletal Muscles of Diabetic Patients with Critical Limb Ischemia
( American Diabetes Association , 2016 , Article)Critical limb ischemia (CLI), foot ulcers, former amputation and impaired regeneration are independent risk factors for limb amputation in diabetic subjects. The present work investigates whether and by which mechanism ... -
Active agents loaded extracellular matrix mimetic electrospun membranes for wound healing applications
( Editions de Sante , 2021 , Article)Achieving the healing of chronic diabetic ulcers, burn wounds and large traumatic wounds is a major clinical challenge. A variety of approaches have been undertaken to generate skin substitutes, wound healing patches or ... -
Active and reactive power management of photovoltaic-based interline dynamic voltage restorer in low voltage distribution networks
( IEEE Computer Society , 2012 , Conference Paper)A dynamic voltage restorer (DVR) is a series connected device that can support the voltage at existing critical loads during voltage sags. Voltage restoration may need active and/or reactive power injection into the ... -
Active and stable methane oxidation nano-catalyst with highly-ionized palladium species prepared by solution combustion synthesis
( MDPI AG , 2018 , Article)We report on the synthesis and testing of active and stable nano-catalysts for methane oxidation. The nano-catalyst was palladium/ceria supported on alumina prepared via a one-step solution-combustion synthesis (SCS) method. ... -
Active Computing Toward 5G Internet of Things
( Institute of Electrical and Electronics Engineers Inc. , 2022 , Article)The Internet of Things (IoT) contains enormous computing resources. How to fully and efficiently use computing power is a very important research issue. This article proposes an active computing (AC) concept toward IoT. ... -
Active control of noise in ventilation ducts
( Canadian Acoustical Association , 2019 , Conference Paper)Ventilation ducts are often lined with passive absorption material for both thermal insulation and noise and vibration reduction. However, the noise reduction performance is not significant at low frequencies. Active Noise ... -
Active exercisers with a higher orientation toward task-approach goal might experience higher happiness: the mediating role of dispositional self-control
( Taylor and Francis Inc. , 2019 , Article)Active exercisers engage in physical activity or training sessions with intentions that are inherently influenced by stable orientations toward achievement goals (i.e. self-regulatory representations about specific outcomes ... -
Active Learning with Noisy Labelers for Improving Classification Accuracy of Connected Vehicles
( Institute of Electrical and Electronics Engineers Inc. , 2021 , Article)Machine learning has emerged as a promising paradigm for enabling connected, automated vehicles to autonomously cruise the streets and react to unexpected situations. Reacting to such situations requires accurate classification ... -
