– This paper investigates the benefits of Dynamic Spectrum Management (DSM) in terms of reducing the power consumption and improving the data rates in digital-subscriber-line (DSL) networks. The proposed techniques at the three different DSM levels simultaneously also provide a significant improvement in the stability of DSLs. The proposed DSM methods are(More)
—This paper investigates Orthogonal Frequency-Division Multiple-Access (OFDMA) resource-allocation schemes for two-hop relays in a home Powerline Communication (PLC) network. Unlike wireless channels, which can have noticeable path loss and shadow effects to bring a substantial relay gain, the powerline channel usually observes a quality of the relay(More)
— This paper reformulates the multiuser OFDMA resource allocation problems in broadcast and multiple-access channels by defining an equivalent interference channel. The resulting problems are then solved by employing recently-developed low-complexity algorithms for spectrum optimization in the interference channel. The re-formulation averts the(More)
PURPOSE The aim of this report was to introduce a novel "core-membrane" microgel drug-delivery device for spontaneously pulsed release without any external trigger. METHODS The microgel core was prepared with alginate and chitosan. The semipermeable membrane outside the microgel was made of polyelectrolytes including polycation poly(allylamine(More)
Gallbladder cancer (GBC) is one leading cause of cancer-related death worldwide. WW domain-containing oxidoreductase (WWOX) is a tumor suppressor gene which can suppress proliferation of a variety of tumors. However, little was known about the relationships between WWOX and gallbladder cancer. In the current study, we intended to investigate the tumor(More)
AIM To investigate the effects of sodium danshensu on vessel function in isolated rat aortic ring. METHODS Thoracic aortae from normal rats were isolated and equilibrated in organ bath with Krebs-Henseleit buffer and ring tension was recorded. Effects of sodium danshensu on basal tonus of the vessel and its effects on vessel contraction and relaxation(More)
Multi-user rate region maximization for the interference channel has attracted great attention recently. However, close to optimal performance algorithms have high complexity, while the fast and distributed algorithms such as the iterative waterfilling algorithm suffer from poor performances, especially when the interferences are severe. Moreover, a lot of(More)
Due to the impermeability of the blood-brain barrier and the nonselective distribution of drugs in the brain, the therapeutic access to intractable neurological disorders is challenging. In this study, dual brain-targeting polymersomes (POs) functionalized by transferrin and Tet-1 peptide (Tf/Tet-1-POs) promoted the transportation of curcumin into the brain(More)
