Asymptotic distribution of fixed points of pattern-avoiding involutions

, 2017
For a variety of pattern-avoiding classes, we describe the limiting distribution for the number of fixed points for involutions chosen uniformly at random from that class.

Distributional patterns of ?Mawsoniidae (Sarcopterygii: Actinistia) [PDF]

Anais da Academia Brasileira de Ciências, 2014
Mawsoniidae are a fossil family of actinistian fish popularly known as coelacanths, which are found in continental and marine paleoenvironments. The taxon is considered monophyletic, including five valid genera (Axelrodichthys, Chinlea, Diplurus, Mawsonia and Parnaibaia) and 11 genera with some taxonomical controversy (Alcoveria, Changxingia ...

The typical sand-fixing plants in the Ulan Buh desert-oasis area significantly changed the distribution pattern of surface sediments

Frontiers in Environmental Science
Vegetation increases surface roughness, reduces wind speeds and decreases sand carrying capacity, thereby effectively intercepting wind-sand flows and promoting sand deposition.

Intensity Fluctuations in Closed and Open Systems

, 1996
We consider the intensity pattern, generated by a monochromatic source, in a disordered cavity coupled to the environment. For weak coupling, and when the source frequency is tuned to a resonance, the intensity distribution is close to Porter-Thomas ...

DOMINANCE, ASSOCIATION AND DISTRIBUTION PATTERN OF TREE SPECIES IN BURNT FOREST IN EAST KALIMANTAN

Biotropia: The Southeast Asian Journal of Tropical Biology, 2021
Repeated forest fires have high impact on species’ composition. Pioneer species colonize the burnt forest and develop widely up to 30 years after a fire but late-succession species regenerate gradually or even disappear owing to direct impact of fires
