The superior capability of chess experts largely depends on quick automatic processing skills which are considered to be mediated by the caudate nucleus. We asked whether continued practice or rehearsal of the skill over a long period of time can lead to structural changes in this region. We found that, comparing to novice controls, grandmaster and master(More)
Cognitive performance relies on the coordination of large-scale networks of brain regions that are not only temporally correlated during different tasks, but also networks that show highly correlated spontaneous activity during a task-free state. Both task-related and task-free network activity has been associated with individual differences in cognitive(More)
BACKGROUND The major challenge of cultivating genetically modified (GM) rice (Oryza sativa) at the commercial scale is to prevent the spread of transgenes from GM cultivated rice to its coexisting weedy rice (O. sativa f. spontanea). The strategic development of GM rice with a built-in control mechanism can mitigate transgene spread in weedy rice(More)
There is increasing momentum towards international harmonization of warning standards. Therefore, it is critical to determine the applicability of existing standards across different cultures. Perceived hazard in response to isolated warning components (colors, signal words and symbols) and warning configurations was examined as a function of culture of the(More)
The immunological mechanism mediated by T cells is the main therapeutic target in the treatment of renal cell carcinoma (RCC) with interleukin (IL)-2 and interferon (IFN)-α. The aim of the present study was to evaluate the role of B7-H4 in the IL-2, IFN-α and IFN-γ treatment of clear cell RCC (ccRCC). A total of 154 paraffin‑embedded ccRCC tissues were(More)
A delay-aware resource allocation algorithm for the heterogeneous multi-radio access (MRA) system, where multiple mobile terminals are served by long term evolution (LTE) and wireless local area network (WLAN) access technologies, is proposed in this paper. Taking both the queue dynamics and physical layer metrics into account when modeling the problem, the(More)
Femtocell with the open access mode benefits the macrocell users (MUE) which locate closely to the femtocell base station (FBS). However, how to enhance these users' performance with the femtocell registered users quality of service (QoS) protection becomes a major problem. Deploying relay outside the femtocell networks is an economical and effective option(More)
