Homoclinic solutions for a class of second-order Hamiltonian systems with locally defined potentials
Electronic Journal of Differential Equations, 2017 In this article, we establish sufficient conditions for the existence of homoclinic solutions for a class of second-order Hamiltonian systems $$ \ddot u(t)-L(t)u(t)+\nabla W\bigl(t,u(t)\bigr)=f(t), $$ where L(t) is a positive definite symmetric ...

Asian Journal of Control, EarlyView.Abstract The linear‐quadratic regulator (LQR) problem of optimal control of an uncertain discrete‐time linear system (DTLS) is revisited in this paper from the perspective of Tikhonov regularization. We show that an optimally chosen regularization parameter reduces, compared to the classical LQR, the values of a scalar error function, as well as the ...

Biochemistry and Molecular Biology Education, EarlyView.ABSTRACT In previous work, we described the development and implementation of new pedagogical practices aimed at enhancing literacy, critical thinking, and communication skills development in a third‐year undergraduate molecular biology course. The online nature and large size of the course presented challenges regarding student engagement and access ...

Analysis of Saccular Function With Vestibular Evoked Myogenic Potential Test in Meniere's Disease
Acta Medica Iranica, 2017 Meniere’s disease is the disorder of inner ear characterized by vertigo, tinnitus and sensorineural hearing loss. The vestibular evoked myogenic potential (VEMP) test could be useful in the analysis of saccular function, and diagnosis of Meniere’s ...

The bootstrap of points and lines
Journal of High Energy PhysicsWe study two-dimensional conformal field theories (CFTs) with boundaries via the conformal bootstrap. We derive a positive semi-definite program from crossing symmetry of three observables: the annulus partition function, the two-point function of ...

Predicting cervical cancer DNA methylation from genetic data using multivariate CMMP
Canadian Journal of Statistics, EarlyView.Abstract Epigenetic modifications link the environment to gene expression and play a crucial role in tumour development. DNA methylation, in particular, is gaining attention in cancer research, including cervical cancer, the focus of this study.

Hidden Markov graphical models with state‐dependent generalized hyperbolic distributions
Canadian Journal of Statistics, EarlyView.Abstract In this article, we develop a novel hidden Markov graphical model to investigate time‐varying interconnectedness between different financial markets. To identify conditional correlation structures under varying market conditions and accommodate shape features embedded in financial time series, we rely upon the generalized hyperbolic family of ...

A partial envelope approach for modelling multivariate spatial‐temporal data
Canadian Journal of Statistics, EarlyView.Abstract In the new era of big data, modelling multivariate spatial‐temporal data is a challenging task due to both the high dimensionality of the features and complex associations among the responses across different locations and time points.
