Enumeration of cyclic vertices and components over the congruence a¹¹ ≡ b (mod n) [PDF]

Notes on Number Theory and Discrete Mathematics, 2023
For each positive integer n, we assign a digraph Γ(n,11) whose set of vertices is Zₙ={0,1,2,...,n-1} and there exists exactly one directed edge from the vertex a to the vertex b iff a¹¹ ≡ b (mod n).

Unknotted Cycles

The Electronic Journal of Combinatorics, 2022
Noting that cycle diagrams of permutations visually resemble grid diagrams used to depict knots and links in topology, we consider the knot (or link) obtained from the cycle diagram of a permutation. We show that the permutations which correspond in this way to an unknot are enumerated by the Schröder numbers, and also enumerate the permutations ...

Hypothesis and Theory: A Two-Process Model of Torpor-Arousal Regulation in Hibernators

Frontiers in Physiology, 2022
Hibernating mammals drastically lower their metabolic rate (MR) and body temperature (Tb) for up to several weeks, but regularly rewarm and stay euthermic for brief periods.

Organic, Gas, and Element Geochemistry of Hydrothermal Fluids of the Newly Discovered Extensive Hydrothermal Area in the Wallis and Futuna Region (SW Pacific)

Geofluids, 2018
Two newly discovered hydrothermal vent fields of the Wallis and Futuna region, Kulo Lasi and Fatu Kapa, were sampled for fluid geochemistry. A great geochemical diversity was observed and assigned to the diversity of lithologies as well as the occurrence

Intransitive preferences or choice errors? A reply to Birnbaum

Judgment and Decision Making, 2020
Birnbaum (2020) reanalyses the data from Butler and Pogrebna (2018) using his ‘true and error’ test of choice patterns. His results generally support the evidence we presented in that paper.

MONEY CYCLES [PDF]

International Economic Review, 2010
Operating overheads are widespread and lead to concentrated bursts of activity. To transfer resources between active and idle spells, agents demand financial assets. Futures contracts and lotteries are unsuitable, as they have substantial overheads of their own.

Impact of primary production and net ecosystem metabolism on carbon and nutrient cycling at the land-sea interface

Frontiers in Marine Science
Estuaries are typically net heterotrophic systems and a source of CO2 to the atmosphere, while continental shelves are net CO2 sinks. Yet, primary production and net ecosystem metabolism (NEM) are variable, and this has implications for nutrient and ...
