Perturbation method for non-square Hamiltonians and its application to polynomial oscillators

, 2005
A remarkable extension of Rayleigh-Schroedinger perturbation method is found. Its (N+q) x (N+1) - dimensional Hamiltonians (as emerging, e.g., during quasi-exact constructions of bound states) are non-square matrices at q > 1.

Floating Phase in 1D Transverse ANNNI Model

, 2006
To study the ground state of ANNNI chain under transverse field as a function of frustration parameter $\kappa$ and field strength $\Gamma$, we present here two different perturbative analyses. In one, we consider the (known) ground state at $\kappa=0.5$

CellPolaris: Transfer Learning for Gene Regulatory Network Construction to Guide Cell State Transitions

Advanced Science, EarlyView.
CellPolaris decodes how transcription factors guide cell fate by building gene regulatory networks from transcriptomic data using transfer learning. It generates tissue‐ and cell‐type‐specific networks, identifies master regulators in cell state transitions, and simulates TF perturbations in developmental processes.

PERTURBATION RESULTS RELATED TO PALINDROMIC EIGENVALUE PROBLEMS [PDF]

The ANZIAM Journal, 2008
Abstract We investigate the perturbation of the palindromic eigenvalue problem for the matrix quadratic $P(\lambda ) = \lambda ^2 A_1^\star + \lambda A_0 + A_1$ with A0,A1∈𝒞n×n and $A_0^\star = A_0$ (where $\star = T$ or H).

A Versatile Three Dimensional Traction Force Microscopy Framework for Uncovering the Mechanics of Bio‐Adhesion

Advanced Science, EarlyView.
This study introduces a versatile platform for quantifying three dimensional traction forces at bio‐adhesive interfaces. Integrating in situ stereo‐digital image correlation with finite element simulations allows for precise measurement of microscale displacements and traction forces in both dry and wet conditions.

Analysis of Semi-Blind Channel Estimation in Multiuser Massive MIMO Systems With Perturbations

IEEE Access, 2019
In the massive multiple-input multiple-output (MIMO) systems, pilot contamination and signal perturbation are two important issues in the semi-blind channel estimation methods.
