Transient Nonlinear Response of Impulsively-Loaded Circular Plates
Engineering Transactions, 1981 The finite element procedure used in this study is based on the incremental Lagrangian approach. Geometrical nonlinearity is included. The elastic viscoplastic material model is adopted in a form suitable for large strains. Linear 2-noded and parabolic 3-

Influence of Excitation Disturbances on Oscillation of a Belt System with Collisions
MachinesIn addition to technological influences, real-world belt and conveyor systems must contend with loading effects characterized primarily by randomness.

On Round-off Error for Adaptive Finite Element Methods
Procedia Computer Science, 2012 AbstractRound-off error analysis has been historically studied by analyzing the condition number of the associated matrix. By controlling the size of the condition number, it is possible to guarantee a prescribed round-off error tolerance. However, the opposite is not true, since it is possible to have a system of linear equations with an arbitrarily ...

Design and analysis strategies for robust microbiome ageing research
FEBS Letters, EarlyView.The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

An Iterative Algorithm for the Reflexive Solution of the General Coupled Matrix Equations
The Scientific World Journal, 2013 The general coupled matrix equations (including the generalized coupled Sylvester matrix equations as special cases) have numerous applications in control and system theory.

Simplicial fixed point algorithm with 2d integer labels
Учёные записки Казанского университета: Серия Физико-математические науки, 2019 Simplicial fixed point algorithms can be based on either integer or vector labels. An apparent advantage of the algorithms with integer labels is their simplicity and stability under round-off errors due to the discrete nature of integer labels.

On the round-off error in the method of successive over-relaxation [PDF]
Mathematics of Computation, 1964 The asymptotic behavior of the round-off error, which accumulates when the well-known iterative method of (point) successive over-relaxation is used to solve a large-scale system of linear equations, is examined by means of a statistical model. The local round-off errors are treated as independent random variables and expressions for the mean and ...

Molecular Oncology, EarlyView.Loss of the miR‐214/199a cluster is associated with recurrence in ovarian cancer. Engineered small extracellular vesicles (m214‐sEVs) elevate miR‐214‐3p/miR‐199a‐5p in tumor cells, suppress β‐catenin, TLR4, and YKT6 signaling, reprogram tumor‐derived sEV cargo, reduce chemoresistance and migration, and enhance carboplatin efficacy and survival in ...
