Stochastic parameterizations are increasingly becoming skillful in representing unresolved atmospheric processes for global climate models. The stochastic multicloud model, used to simulate the life cycle of the three most ...

Phenotypic evolution through deep time is slower than expected from microevolutionary rates. This is the paradox of stasis. Previous models suggest stasis occurs because populations track adaptive peaks that remain relatively ...

Aim: A universal attribute of species is that their distributions are limited by numerous factors that may be difficult to quantify. Furthermore, climate change‐induced range shifts have been reported in many taxa, and ...

Empirical studies show that lineages typically exhibit long periods of evolutionary stasis and that relative levels of within‐species trait covariance often correlate with the extent of between‐species trait divergence. ...
Central and peripheral respiratory chemoreceptors are stimulated during voluntary breath holding due to chemostimuli (i.e., hypoxia and hypercapnia) accumulating at the metabolic rate. We hypothesized that voluntary ...

Motivated by problems involving triangle-decompositions of graphs, we examine the facet structure of the cone τn of weighted graphs on n vertices generated by triangles. Our results include enumeration of facets for small ...

We consider maximum packings of edge-disjoint 4-cliques in the complete graph Kn. When n 1 or 4 (mod 12), these are simply block designs. In other congruence classes, there are necessarily uncovered edges; we examine the ...
Dukes, Peter J.; Bowditch, Flora Caroline(arXiv, 2020)
In a balanced graph decomposition, every vertex of the host graph appears in the same number of blocks. We propose the use of colored loops as a framework for unifying various other types of local balance conditions in ...

It is known that N(n), the maximum number of mutually orthogonal latin squares
of order n, satisfies the lower bound N(n) > n1/14.8 for large n. For h > 2, relatively little is
known about the quantity N(hn), which denotes ...

In this paper, we consider a weakening of the de nitions of uniform and perfect
one-factorizations of the complete graph. Basically, we want to order the 2n − 1
one-factors of a one-factorization of the complete graph ...

A complete k-colouring of a hypergraph is an assignment of k colours to the points such that (1) there is no monochromatic hyperedge, and (2) identifying any two colours produces a monochromatic hyperedge. The achromatic ...

The dimension of a block design is the maximum positive
integer d such that any d of its points are contained in a proper subdesign.
Pairwise balanced designs PBD(v, K) have dimension at least two as long as
not all ...

Monitoring coral reefs is vital to the conservation of these at-risk ecosystems. While most current monitoring methods are costly and time-intensive, passive acoustic monitoring (PAM) could provide a cost-effective, large ...

In this paper, generalized fractional-order Bernoulli wavelet functions based on the Bernoulli wavelets are constructed to obtain the numerical solution of problems of anomalous infiltration and diffusion modeling by a ...

Eukaryotic microbes (protists) that occupy low-oxygen environments often have drastically different mitochondrial metabolism compared to their aerobic relatives. A common theme among many anaerobic protists is the serial ...
Srivastava, H.M.; Deniz, Sinan; Saad, Khaled M.(Journal of King Saud University - Science, 2021)
In this work, the newly developed optimal perturbation iteration technique with Laplace transform is applied to the generalized regularized long wave equations with a new fractional operator to obtain new approximate ...
Effective cancer therapy requires identification of signaling networks and investigating their potential role in proliferation and invasion of cancer cells. Among molecular pathways, signal transducer and activator of ...
Multidisciplinary approaches are increasingly being used to elucidate the role of autophagy in health and disease and to harness it for therapeutic purposes. The broad range of topics included in the program of the Vancouver ...

We use a general autonomous discrete-time infectious disease model to extend the next generation matrix approach for calculating the basic reproduction number, R0, to account for populations with locally asymptotically ...

We show that the necessary divisibility conditions for the existence ofaσ-resolvable BIBD(v,k,λ) are sufficient for largev. The key idea isto form an auxiliary graph based on an [r,k]-configuration ...
