PENGUIN is a grammar-based language for programming graphical user interfaces. Code for each thread of control in a multi-threaded application is confined to its own module, promoting modularity and reuse of code. Networks of PENGUIN components (each composed of an arbitrary number of modules) can be used to construct large reactive systems with parallel execution, internal protection boundarie...

Radiative penguin decays provide an indirect probe for physics beyond the Standard Model and contribute to the determination of the CKM matrix elements. Copious quantities of B mesons produced at the B–Factories permit precision measurements of radiative penguin decays. We review the experimental status of the radiative penguin processes b → s(d)γ.

Most studies on phosphorus cycle in the natural environment focused on phosphates, with limited data available for the reduced phosphine (PH3). In this paper, matrix-bound phosphine (MBP), gaseous phosphine fluxes and phosphorus fractions in the soils were investigated from a penguin colony, a seal colony and the adjacent animal-lacking tundra and background sites. The MBP levels (mean 200.3 ng...

ABSTR•CT.--Territorial and foraging behavior of the South Polar Skua (Catharacta maccormicki) were studied in 1971-72 at the Cape Hallett Adglie Penguin (Pygoscelis adeliae) rookery. The skua population was at maximum 98 pairs, and the Adglie Penguin population was some 43,000 pairs. The size of the skuas' territories varied between 0.5 and 1.8 ha (between 730 and 3,190 penguin pairs). Areas be...

Interactions with wildlife can contribute to biodiversity conservation outcomes, though safety and accessibility considerations limit animal encounters from being a viable strategy. This investigation explores the feasibility of mobile augmented reality facilitate interactions encourage biodversity conservation. A experience (Snapchat lens), titled “Penguin Rescue!”, was created allow users reh...

Africa hosts a single breeding species of penguin today, yet the fossil record indicates that a diverse array of now-extinct taxa once inhabited southern African coastlines. Here, we show that the African penguin fauna had a complex history involving multiple dispersals and extinctions. Phylogenetic analyses and biogeographic reconstructions incorporating new fossil material indicate that, cont...

The main soil physical-chemical features, the concentrations of a set of pollutants, and the soil microbiota linked to penguin rookeries have been studied in 10 selected sites located at the South Shetland Islands and the Antarctic Peninsula (Maritime Antarctica). This study aims to test the hypothesis that biotransport by penguins increases the concentration of pollutants, especially heavy met...

Penguins are a group of flightless seabirds that exhibit numerous morphological, behavioral and ecological adaptations to their amphibious lifestyle, but little is known about the topographic organization of neurons in their retinas. In this study, we used retinal wholemounts and stereological methods to estimate the total number and topographic distribution of retinal ganglion cells in additio...

Isospin-breaking effects, in particular those associated with electroweakpenguin contributions and π-η, η mixing, have long been known to affect the Standard Model prediction of ǫ/ǫ in a significant manner. We have found an heretofore unconsidered isospin-violating effect of importance; namely, the u-d quark mass difference can spawn |∆I| = 3/2 components in the matrix elements of the gluonic p...

By a multitude of very important observations involving the QCD penguin, CLEO [1] has declared 1997 to be the year of the Strong Penguin. The observed size of the various modes suggest that the penguin is rather robust. The experimental observations have fueled intense theoretical activity some of which we will briefly review here. For convenience, we have divided the theoretical activity into ...
