We consider the problem of energy-efficient base-station (BS) planning for green cellular network design. There exist a number of criteria for greenness in the literature, but we focus only on the energy-normalized throughput. We first model energy consumption for a heterogeneous network, consisting of macro and micro base-stations, and a network topology.(More)
Abnormal accumulation of β-amyloid (Aβ) is the main characteristic of Alzheimer’s disease (AD) brain and Aβ peptides are generated from proteolytic cleavages of amyloid precursor protein (APP) by β-site APP-converting enzyme 1 (BACE1) and presenilin 1 (PS1). Sphingosylphosphorylcholine (SPC), a choline-containing sphingolipid, showed suppressive effect on(More)
ETHNOPHARMACOLOGICAL RELEVANCE Typha angustata is used in traditional Chinese medicine for a variety of clinical disorders. Its pharmacological actions include beneficial effects on hyperlipidemia and myocardial infarction, as well as labor-inducing and antibacterial effects. AIM OF THE STUDY We investigated the mechanism underlying the ability of(More)
Naphthoquinone derivatives have been reported to possess various pharmacological activities, such as antiplatelet, anticancer, antifungal, and antiviral properties. In this study, we investigated the effects of a newly-synthesized naphthoquinone derivative, 2-decylamino-5,8-dimethoxy-1,4-naphthoquinone (2-decylamino-DMNQ), on VSMC proliferation and examined(More)
Diversity-multiplexing tradeoff (DMT) characterizes the fundamental relationship between the diversity gain in terms of outage probability and the multiplexing gain as the normalized rate parameter , where the limiting transmission rate is given by (here, SNR denote the received signal-to-noise ratio). In this paper, we analyze the DMT and outage(More)
We solve the problem of environmentally friendly (i.e., energy-efficient) base station and relay-station planning for a simplified cooperative cellular network. We assume a two-hop transmission model based on the time-division multiplexing operation. We propose a twostep iterative algorithm where each iteration consists of an assignment step and a(More)
Recent global concerns about greenhouse gas necessitate new approach to every element of information and communication technology. Therefore, considering a greenness as another constraint in base-station planning problem is required. There exists a large body of work on network design and base-station planning, but these have not taken greenness into(More)
