Time-of-Flight Measurements in the Jet of a High-Current Vacuum Arc Thruster

Aerospace, 2023
Measurements of ion speed in the plume of a pulsed high-current vacuum arc thruster were performed by means of electrostatic probes. The probes were designed to provide direct speed measurements with minimum disturbance on the plasma jet.

Carbon Recycling Through CO2-Conversion for Stepping Toward a Cyclic-C Economy. A Perspective

Frontiers in Energy Research, 2020
The conversion of CO2 into added value chemicals, materials and fuels is a case of transition from the linear to the cyclic-C economy, a necessary change for stopping the putative negative effect of CO2 on climate and the environment.

Melatonin Reduces Oxidative Stress in the Right Ventricle of Newborn Sheep Gestated under Chronic Hypoxia

Antioxidants, 2021
Pulmonary arterial hypertension of newborns (PAHN) constitutes a critical condition involving both severe cardiac remodeling and right ventricle dysfunction. One main cause of this condition is perinatal hypoxia and oxidative stress. Thus, it is a public

Partial Oxidation of Methane to Syngas Over Nickel-Based Catalysts: Influence of Support Type, Addition of Rhodium, and Preparation Method

Frontiers in Chemistry, 2019
There is great economic incentive in developing efficient catalysts to produce hydrogen or syngas by catalytic partial oxidation of methane (CPOM) since this is a much less energy-intensive reaction than the highly endothermic methane steam reforming ...

Neuroimaging assessment of cerebrovascular reactivity in concussion: current concepts, methodological considerations and review of the literature

Frontiers in Neurology, 2016
Concussion is a form of traumatic brain injury (TBI) that presents with a wide spectrum of subjective symptoms and few objective clinical findings. Emerging research suggests that one of the processes that may contribute to concussion pathophysiology is ...

Distributed Reactive Programming for Reactive Distributed Systems [PDF]

The Art, Science, and Engineering of Programming, 2019
Context: The term reactivity is popular in two areas of research: programming languages and distributed systems. On one hand, reactive programming is a paradigm which provides programmers with the means to declaratively write event-driven applications. On the other hand, reactive distributed systems handle client requests in a timely fashion regardless

Identification of RNase L-Dependent, 3′-End-Modified, Viral Small RNAs in Sindbis Virus-Infected Mammalian Cells

mBio, 2013
Small RNAs play a critical role in host-pathogen interaction. Indeed, small RNA-mediated silencing or RNA interference (RNAi) is one of the earliest forms of antiviral immunity.
