Lump Solutions to a (2+1)-Dimensional Fifth-Order KdV-Like Equation
Advances in Mathematical Physics, 2018 A (2+1)-dimensional fifth-order KdV-like equation is introduced through a generalized bilinear equation with the prime number p=5. The new equation possesses the same bilinear form as the standard (2+1)-dimensional fifth-order KdV equation.

Immersed Boundary Projection Method for Boundaries With Slip Velocities
International Journal for Numerical Methods in Fluids, EarlyView.A formulation of the immersed boundary method for incompressible flow over arbitrarily‐shaped bodies with surface slip described by the Navier boundary condition is presented. The wall slip velocity and the boundary force are determined implicitly through a projection to satisfy both the boundary condition and the divergence‐free condition of the ...

Decomposition of bilinear forms as sums of bounded forms [PDF]
Journal of Operator Theory, 2016 The problem of decomposition of bilinear forms which satisfy a certain condition has been studied by many authors by example in \cite{H08}: Let $H$ and $K$ be Hilbert spaces and let $A,C \in B(H),B,D\in B(K)$. Assume that $u:H\times Karrow \C$ a bilinear form satisfies \[ |u(x,y)|\leq\|Ax\|\ \|By\|+\|Cx\|\|Dy\| \] for all $ x\in H$ and $y\in K$. Then u

Threshold Asymmetric Conditional Autoregressive Range (TACARR) Model
Journal of Forecasting, EarlyView.ABSTRACT This paper introduces a Threshold Asymmetric Conditional Autoregressive Range (TACARR) model for analyzing the daily price ranges of financial assets. The proposed formulation assumes that the conditional expected range switches between two regimes, representing upward and downward market states, with the disturbance distribution also allowed ...

Line Graphs of Multigraphs and the Forbidden Graph E 6
Journal of Graph Theory, EarlyView.ABSTRACT The line graph Γ of a multigraph Δ is the graph whose vertices are the edges of Δ, where two such edges are adjacent if and only if they meet in a single vertex of Δ. We provide several characterizations of such line graphs and in particular show that a graph is a line graph if and only if it does not contain one of the 32 graphs, all of which

Enriched P1-Conforming Methods for Elliptic Interface Problems with Implicit Jump Conditions
Advances in Mathematical Physics, 2018 We develop a numerical method for elliptic interface problems with implicit jumps. To handle the discontinuity, we enrich usual P1-conforming finite element space by adding extra degrees of freedom on one side of the interface.

Changing Water Resources in the Indus Basin: A Multi‐Model Budyko‐Based Analysis
International Journal of Climatology, EarlyView.Budyko‐based analysis evaluates historical (1962–2005) and future hydroclimatic change across the Indus River Basin. Budyko shifts indicate rising atmospheric evaporative demand and increasing energy limitation under future scenarios. ABSTRACT Assessing hydroclimatic variability and future water availability is crucial for sustainable water‐resource ...

On Backlund transformations and identities in bilinear form [PDF]
Journal of Physics A: Mathematical and General, 1990 Summary: For bilinear equations of the form \(P(D)f\cdot f=0\) we find all possibilities for rewriting \(g^ 2P(D)f\cdot f-f^ 2P(D)g\cdot g=0\) in the form \(Q(D)f\cdot g=0\). This is the first step in finding a Bäcklund transformation.

International Journal of Climatology, EarlyView.The study provides insights for post‐processing climate model output in complex terrain, useful for climate change impact models. We compared different bias adjustment and downscaling techniques from quantile delta mapping to simple lapse rates. We developed a new spatial downscaling method based on principal components analysis, which showed superior ...
