—Sensor Web, as an extension of Sensor Networks, is expected to be used in the distributed, large-scale environment. With the help of Internet, its application can even be extended to the world wide. And in the distributed environment, a Sensor Web usually consists of different sensor networks or single sensor owned by different organizations such as(More)
Using non-equilibrium molecular dynamics and Monte Carlo methods, we have studied the molecular transport in asymmetric nanochannels. The efficiency of the molecular pump depends on the angle and apertures of the asymmetric channel, the environmental temperature and average concentration of the particles. The pumping effect can be explained as the(More)
Multifocal hepatic hemangioma (MHH) is a benign hepatic tumor that is commonly diagnosed in children with multiple cutaneous infantile hemangiomas (IHs). We present a review of all children with MHH at our institutions. Of the 42 patients, the median age at presentation of MHH was 2.5 months. Thirty-six (85.7%) patients had cutaneous IHs. Twelve (28.6%)(More)
Propranolol, a lipophilic nonselective b-blocker, has recently been reported to be the treatment of choice for select types of infantile hemangiomas (IHs). Atenolol is a hydrophilic, selective b 1-blocker and therefore may be not associated with side effects attributable to b 2-adrenergic receptor blockade and lipophilicity. However, the efficacy and safety(More)
