    Elevated nuclear TDP-43 induces constitutive exon skip**

    Cytoplasmic inclusions and loss of nuclear TDP-43 are key pathological features found in several neurodegenerative disorders, suggesting both gain- and loss-of-function mechanisms of disease. To study gain-of-...

    A Fuzzy Convex Nonparametric Least Squares Method with Different Shape Constraints

    The main drawback of the typical fuzzy least squares approach is that the resulting fuzzy regression model is linear, and the model's accuracy decreases with the increases in the magnitudes and the number of i...

    Sensory reweighting: a common mechanism for subjective visual vertical and cybersickness susceptibility

    The malaise symptoms of cybersickness are thought to be related to the sensory conflict present in the exposure to virtual reality (VR) content. When there is a sensory mismatch in the process of sensory perce...

    Truncated Dantzig–Wolfe Decomposition for a Class of Constrained Variational Inequality Problems

    In this paper, we discuss how to use the Dantzig–Wolfe (DW) decomposition method to solve a class of constrained variational inequality (VI) problems. These problems include multi-regional energy equilibrium m...

    An application of statistical and data mining methods to study the waste charging scheme in Hong Kong

    Waste charging policy is one of the tools used by many countries to solve waste management problems. Before a policy can be fully implemented, it is important to study residents’ willingness to pay (WTP) for w...

    Dantzig—Wolfe Decomposition of Variational Inequalities

    The creation and ongoing management of a large economic model can be greatly simplified if the model is managed in separate smaller pieces defined, e.g. by region or commodity. For this purpose, we define an e...
