Range gate dependence of specular echoes [PDF]

open access: yes, 1983
Some controversy has surrounded the interpretation of the enhancement of VHF radar echoes at vertical incidence (also known as partial reflections, specular reflections and Fresnel scattering) since they were reported by the Sunset and the SOUSY radars ...

The orientation of the Mithraea in Ostia Antica [PDF]

open access: yes, 2016
We conducted an investigation on the orientations and geometrical content of the Mithraea of Ostia Antica. A geometrical CAD study based on the most reliable plans from the Archives of the Sovrintendenza Speciale per il Colosseo, il MNR e l’Area ...

Prolonged low flows and non‐native fish operate additively to alter insect emergence in mountain streams

open access: yesLimnology and Oceanography, EarlyView.
Abstract Climate‐induced flow alteration is decreasing snowpack and advancing snowmelt, subjecting mountain streams to longer low‐flow periods. Yet, anticipating how stream ecosystems respond to prolonged low flows remains challenging because distinct trophic levels can respond differently, and non‐native predators can dampen or amplify responses. Here,

Local mirror symmetry and the sunset Feynman integral [PDF]

open access: yes, 2016
We study the sunset Feynman integral defined as the scalar two-point self-energy at two-loop order in a two dimensional space-time. We firstly compute the Feynman integral, for arbitrary internal masses, in terms of the regulator of a class in the ...

Warming enhances primary production and respiration and changes plankton community structure in an estuarine upwelling system

open access: yesLimnology and Oceanography, EarlyView.
Abstract Marine heatwaves are expected to become more frequent and intense due to global climate change, potentially impacting plankton communities. In the present study, the effects of a simulated short‐term warming event on the structure and functioning of coastal plankton communities were investigated during a mesocosm experiment conducted with ...

A large, infrequent ecosystem subsidy (cicada carcasses) and warming additively accelerate development and increase growth of larval amphibians

open access: yesLimnology and Oceanography, EarlyView.
Abstract Many ecosystems receive resource subsidies that affect productivity and food webs. Ecosystem subsidies vary in quantity, quality, and timing, and effects are often mediated by environmental factors, including temperature. Deposition of periodical cicada carcasses into ponds represents a large, high‐quality, infrequent subsidy.

Optimized Hybrid Resource Allocation in Wireless Cellular Networks with and without Channel Reassignment

open access: yesJournal of Computer Systems, Networks, and Communications, 2010
In cellular networks, it is important to determine an optimal channel assignment scheme so that the available channels, which are considered as “limited” resources in cellular networks, are used as efficiently as possible.

Temporal Variability of Atmospheric Total Gaseous Mercury in Windsor, ON, Canada

open access: yesAtmosphere, 2014
Atmospheric Total Gaseous Mercury (TGM) concentrations were monitored in Windsor, Ontario, Canada, during 2007 to 2011, to investigate the temporal variability of TGM. Over five years, the average concentration was 2.0 ± 1.3 ng/m3.
