Ecological Applications, Volume 32, Issue 8, December 2022., 2022 Abstract Coastal wetlands are globally important stores of carbon (C). However, accelerated sea‐level rise (SLR), increased saltwater intrusion, and modified freshwater discharge can contribute to the collapse of peat marshes, converting coastal peatlands into open water.

LIFTS OF THE TERNARY QUADRATIC RESIDUE CODE OF LENGTH 24 AND THEIR WEIGHT ENUMERATORS [PDF]
Korean Journal of Mathematics, 2012 A digraph $D$ is primitive if there is a positive integer $k$ such that there is a walk of length $k$ between arbitrary two vertices of $D$. The exponent of a primitive digraph is the least such $k$. Wielandt graph $W_n$ of order $n$ is known as the digraph whose exponent is $n^2 − 2n + 2$, which is the maximum of all the exponents of the primitive ...

Anti-pre-Lie algebras, Novikov algebras and commutative 2-cocycles on Lie algebras [PDF]
Journal of Algebra (2022) 609: 337-379, 2022 Anti-pre-Lie algebras, Novikov algebras and commutative 2-cocycles on Lie algebrasWe introduce the notion of anti-pre-Lie algebras as the underlying algebraic structures of nondegenerate commutative 2-cocycles which are the "symmetric" version of symplectic forms on Lie algebras.

From Rota-Baxter Algebras to Pre-Lie Algebras [PDF]
Journal of Physics A; Mathematical and Theoretical (2008) 015201, 2007 Rota-Baxter algebras were introduced to solve some analytic and combinatorial problems and have appeared in many fields in mathematics and mathematical physics. Rota-Baxter algebras provide a construction of pre-Lie algebras from associative algebras.

The SHARK integral generation and digestion system
Journal of Computational Chemistry, Volume 44, Issue 3, Page 381-396, January 30, 2023., 2023 The BLAS level 3‐driven SHARK integral generation and digestion library is introduced and it is discussed how it leads to greatly simplified workflows and substantial computational speedups. Abstract In this paper, the SHARK integral generation and digestion engine is described.

Cohomology of moduli spaces of Del Pezzo surfaces
Mathematische Nachrichten, Volume 296, Issue 1, Page 80-101, January 2023., 2023 Abstract We compute the rational Betti cohomology groups of the coarse moduli spaces of geometrically marked Del Pezzo surfaces of degree 3 and 4 as representations of the Weyl groups of the corresponding root systems. The proof uses a blend of methods from point counting over finite fields and techniques from arrangement complements.

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 47, Issue 2, Page 145-186, 10 February 2023., 2023 Abstract A two‐phase velocity‐pressure stabilized formulation is proposed for the numerical analysis of mechanized excavations in partially saturated soft soils using the Particle Finite Element Method (PFEM). The fully coupled formulation is based on the theory of porous media in association with the Soil Water Characteristic Curve and the porosity ...

Networks, Volume 81, Issue 1, Page 3-22, January 2023., 2023 Abstract We introduce generalizations of stochastic network interdiction problem with distributional ambiguity. Specifically, we consider a distributionally risk‐averse (or robust) network interdiction problem (DRA‐NIP) and a distributionally risk‐receptive network interdiction problem (DRR‐NIP) where a leader maximizes a follower's minimal expected ...
