The elliptic dilogarithm for the sunset graph
, 2013 We study the sunset graph defined as the scalar two-point self-energy at two-loop order. We evaluate the sunset integral for all identical internal masses in two dimensions.

Sustainable Development, EarlyView.ABSTRACT The design of lighting systems, has, in recent years, transcended the basic function of providing visibility, becoming a key component of promoting the health and well‐being of occupants by integrating biological, psychological, and energy aspects. The growing understanding of the effects of light on the circadian cycle has posed a fundamental

Beyond Supply and Demand: The Moral Economy of Price Formation in Slab City
Economic Anthropology, EarlyView.ABSTRACT This article investigates the unique economic practices of Slab City, California, an off‐grid community that rejects mainstream US values. Despite operating within the broader US economic system, Slab City residents have developed alternative forms of exchange, using cigarettes and cannabis alongside US dollars.

Practicality of electronic beam steering for MST/ST radars, part 6.2A [PDF]
Electronic beam steering is described as complex and expensive. The Sunset implementation of electronic steering is described, and it is demonstrated that such systems are cost effective, versatile, and no more complex than fixed beam alternatives ...

Threshold and pseudothreshold values of the sunset diagram
, 1997 Analytic results for the threshold and pseudothreshold values of the sunset diagram with arbitrary masses are obtained in terms of dilogarithms of ratios of the masses.Comment: 11 pages, plain ...

Pathogens and Immunity, 2017 IntroductionDaniel DouekWe are very fortunate to introduce two poems from two great immunologists, Alex Whelan and Irun Cohen. Alex’s poem, titled “Aleppo,” is a stark insight into the horrors which scar the population of that blighted city. Irun has written a haiku in response which evokes the interminable nature of that horror.

Small, EarlyView.High efficiency solar steam generators are prepared from hydrothermal treatment of cellulose nanocrystal aerogels as an in‐situ synthesis strategy of solar absorber. They feature a biomimetic unidirectional porous structure from freeze‐drying, with low water evaporation enthalpy, and excellent solar‐driven water purification performance.

On the thermal sunset diagram for scalar field theories
, 2003 We study the so-called `` sunset diagram'', which is one of two-loop self-energy diagrams, for scalar field theories at finite temperature. For this purpose, we first find the complete expression of the bubble diagram, the one-loop subdiagram of the ...
