Regional Differences in the Diets of Adélie and Emperor Penguins in the Ross Sea, Antarctica

open access: yesAnimals, 2021
To identify the dietary composition and characteristics of both Adélie (Pygoscelis adeliae) and Emperor (Aptenodytes forsteri) penguins at four breeding sites, we performed stable carbon (δ13C) and nitrogen (δ15N) isotope analysis of down samples taken ...

Charming penguin contributions to charmless B decays into two pseudoscalar mesons [PDF]

open access: yes, 2001
We present estimates of the charming penguin contribution to B => K pi, pi pi,K eta, K eta' decays due to intermediate charmed meson states. We find that this contribution is indeed significant for B => K pi decays, and its inclusion, together with the ...

Anaesthetic management and complications of a Humboldt penguin (Spheniscus humboldti) undergoing diagnostic imaging

open access: yesIrish Veterinary Journal, 2023
Background The presence of a tracheal septum dividing the trachea into two makes intubation one of the main challenges of penguin anaesthesia. Differences in the length and location of the aforementioned tracheal septum have been described in some ...

Influenza A(H11N2) Virus Detection in Fecal Samples from Adélie (Pygoscelis adeliae) and Chinstrap (Pygoscelis antarcticus) Penguins, Penguin Island, Antarctica

open access: yesMicrobiology Spectrum, 2022
Influenza A viruses infect a range of host species, including a large variety of mammals and more than a hundred species of birds. A total of 95 avian fecal samples were collected from penguin colonies in the South Shetland Islands, close to the ...

Penguins of the Magellan region

open access: yesScientia Marina, 1999
The Magellan region, including the Falkland Islands, is one of the world´s most important areas for seabirds, and especially penguins. World-wide there are 17 species of penguin; 7 of these regularly breed around the coastal waters of South America, and ...

Host Species Adaptation of Obligate Gut Anaerobes Is Dependent on Their Environmental Survival

open access: yesMicroorganisms, 2022
The gut microbiota of warm-blooded vertebrates consists of bacterial species belonging to two main phyla; Firmicutes and Bacteroidetes. However, does it mean that the same bacterial species are found in humans and chickens?

A Possibility of large electro-weak penguin contribution in B -> K pi modes

open access: yes, 2003
We discuss about a possibility of large electro-weak penguin contribution in B -> K pi from recent experimental data. The several relations among the branching ratios which realize when the contributions from tree type and electro-weak penguin are small ...

Development and psychometric properties of Chinese social emotional competence measurements

open access: yesFrontiers in Psychology
IntroductionSocial-emotional competence (SEC) plays a critical role in the personal and academic development of university students. However, there is a lack of culturally appropriate tools to assess SEC in Chinese populations.

Effect of the Space-like Penguin Diagrams on CP Asymmetries in Exclusive B Decays

open access: yes, 1995
The space-like penguin contributions were ignored on little ground in many previous studies of nonleptonic B decays and CP violation. Taking the penguin-dominated channels $B^{-} _{u}\rightarrow \bar{K}^{0}\pi$ and $B^{-}_{u}\rightarrow K^{0} K^{-}$ for ...

Enhancing $l_i \to 3 l_j$ with the $Z^0$-penguin [PDF]

open access: yes, 2012
Lepton flavor violation (LFV) has been observed in neutrino oscillations. For charged lepton FV decays only upper limits are known, but sizable branching ratios are expected in many neutrino mass models.
