The revolutionary Cloud Radio Access Network (C-RAN) enables real-time physical-layer coordination over a large number of distributed remote radio heads (RRHs). Connected via high-bandwidth low-latency optics, RRHs can cooperate dynamically and seamlessly according to user locations or traffic loads. Without limitations on the RRH cooperation, the(More)
Rubber dandelion (Taraxacum kok-saghyz, TK) is being developed as a domestic source of natural rubber to meet increasing global demand. However, the domestication of TK is complicated by its colocation with two weedy dandelion species, Taraxacum brevicorniculatum (TB) and the common dandelion (Taraxacum officinale, TO). TB is often present as a seed(More)
With wireless network virtualization, Mobile Virtual Network Operators (MVNOs) can develop new services on a low-cost platform by leasing virtual resources from mobile network owners. In this paper, we investigate a two-stage spectrum leasing framework, where an MVNO acquires radio spectrum through both advance reservation and on-demand request. To maximize(More)
SCOPE The adverse impacts of dietary advanced glycation end products (AGEs) on health are currently of interest. These compounds are inevitably formed during thermal food processing and make foods less digestible because of protein cross-linking. This study examined not only whether dietary AGEs alter cecal microbiota and their metabolites but also their(More)
Apomixis is the ability of plants to produce asexual seeds, which are clones of the mother plant. The phenomenon of apomixis is tightly linked to ploidy, where diploids lack apomixis and reproduce sexually, while higher ploidy levels can exhibit apomixis. Taraxacum F.H.Wigg. species (dandelions) commonly exhibit apomixis; however, only limited studies have(More)
