Model-independent description of nonleptonic decays charmed mesons is a challenging task due to large nonperturbative effects strong interactions on the transition amplitudes. We discuss equivalence two different flavor-$SU(3)$-based descriptions Cabibbo-favored non-leptonic two-pseudoscalars final states including $\eta$ and $\eta^\prime$ mesons.

In the project-based construction industry, organizations build collaborative relationships through specific projects. The owners and contractors who are key project stakeholders have gradually formed a complex industry-level network in many different projects, closely related to knowledge exchange industry development. Based on data set of National Quality Engineering Award (NQEA) projects Chi...

Impact loading is a major factor in the high prevalence of musculoskeletal injuries among military personnel during operational tasks. One of the therapeutic purposes of a pedorthic approach is to attenuate impact load through footwear and supportive device cushioning. The following research pilot project attempts to investigate this relationship. Vertical acceleration was collected at the four...

Reminiscence may help in resolving conflicts from the past and making up the balance of one's life. Life-review may be further enhanced by the creative expression of memories in stories, poems or drawings. In this way people are encouraged to create and discover metaphors, images and stories that symbolically represent the subjective and inner meaning of their lives. In this article, a new inte...

We introduce a robotic wheelchair that can move with a companion collaboratively to facilitate easy communication between them. The system uses the Laser Range Sensor attached horizontally on the companion’s shoulder level for observing the companion’s position to follow him/her. The system tracks the companion’s position and orientation to move with the companion and to avoid collision with hi...
