Fish Scales: A Multifunctional Biomaterial from Nature
ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.Fish scales demonstrate nature's solution to impact protection through overlapping multilayered architecture. This biological design combines mineralized surfaces with collagen networks to achieve both flexibility and fracture resistance. The structural principles inspire advanced protective materials and biomedical implants, where damage tolerance ...

A bilinear form associated to contact sub-conformal manifolds
, 2007 We define a bilinear form associated to a sub-Riemannian contact manifold. It transforms by scalar multiples under sub-conformal transformations and with further hypothesis it is naturally defined on certain torus bundles over the contact ...

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.

Earthquake Engineering &Structural Dynamics, EarlyView.ABSTRACT This paper illustrates opportunities for the use of simulated ground motions in seismic performance assessment – from seismic hazard, ground‐motion selection, response history analysis, and seismic demand hazard calculation. The illustration is through a comparative analysis with the conventional alternative of observed ground motions.

State maps from integration by parts [PDF]
, 2011 We develop a new approach to the construction of state vectors for linear time-invariant systems described by higher-order differential equations. The basic observation is that the concatenation of two solutions of higher-order differential equations ...

Sensitivity of 3D Base‐Isolated Buildings to Individual Isolator Variability
Earthquake Engineering &Structural Dynamics, EarlyView.ABSTRACT Variability in elastomeric isolators arises from differences in rubber formulation and curing, leading to noticeable changes in stiffness and damping among nominally identical bearings. While most previous studies have examined global isolator variability associated with environmental or aging effects, individual isolator variability has ...

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
