Several flat tendon graft types are viable options for flat superficial medial collateral ligament reconstructions—A biomechanical analysis

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Flat superficial medial collateral ligament (sMCL) reconstruction helps restore knee kinematics in medial instability, but recommendations on grafts that best mimic the sMCL's biomechanical properties are missing. This study aimed to compare the biomechanical properties of flat grafts to the native sMCL, hypothesizing that (1) flat ...

Oxide Formation at the Sulfide Film‐Copper Interface in Anoxic Sulfide Solution and On‐Line Sulfide Detection Via Linear Polarization Resistance

Materials and Corrosion, EarlyView.
A flow through cell arrangement was used to examine the oxide formation at copper–copper sulfide interface in an anoxic, sulfide environment. Oxide formation on surface occurs because of exposure to aerated water during sample preparation. On‐line sulfide detection based on the linear polarization resistance of copper is also presented.

A Question of Trust: Dynamics of the Perceived Uncertainty–Trust Dilemma With Artificial Intelligence in Strategy Process Initiation

Managerial and Decision Economics, EarlyView.
ABSTRACT Strategists who must identify issues in uncertain environments while being cognitively constrained can increasingly rely on artificial intelligence to manage uncertainty. The potential for AI to be incorporated into strategy processes has led to a debate about the evolving collaborative relationship between strategists and AI.

Optimal Equivalent Preconditioners

SIAM Journal on Numerical Analysis, 1993
Preconditioning strategies for elliptic partial differential operators and their discrete counterparts are compared by a model problem. The technique uses a selfadjoint positive definite operator \(B\) as the preconditioner for the nonselfadjoint convection-diffusion operator \(A\). Preconditioning is done by \(A\)'s leading term plus a positive zeroth

Multi-p Preconditioners

SIAM Journal on Scientific Computing, 1997
In analogy with the multigrid method, the authors present a solution method for problems based on the \(p\)-version of the finite element method whereby degrees of freedom associated with approximation order \(p\) are visited at once and separately from those of approximation order \(p-1\) and \(p+1\).

Multiresolution Approximate Inverse Preconditioners

SIAM Journal on Scientific Computing, 2001
Summary: We introduce a new preconditioner for elliptic partial differential equations (PDEs) on unstructured meshes. Using a wavelet-inspired basis we compress the inverse of the matrix, allowing an effective sparse approximate inverse by solving the sparsity vs. accuracy conflict. The key issue in this compression is to use second generation wavelets

Generalized circulant Strang‐type preconditioners

Numerical Linear Algebra with Applications, 2011
SUMMARYStrang's proposal to use a circulant preconditioner for linear systems of equations with a Hermitian positive definite Toeplitz matrix has given rise to considerable research on circulant preconditioners. This paper presents an {eiφ}‐circulant Strang‐type preconditioner. Copyright © 2011 John Wiley & Sons, Ltd.
