The carbon nanomaterails having the brittle star-like morphology (bs-CNMs) could be synthesized using C2H2-SF6 gases under thermal chemical vapour deposition (TCVD) system. The micro-sized Ni grains were used as the catalyst for bs-CNMs on the Al2O3 substrate. The bs-CNMs could be obtained under the condition of the source gases flow rates at 100sccm for C2H2 and 50sccm for SF6. The bs-CNMs wer...

BACKGROUND Buddlejasaponin IV (BS-IV), a triterpene saponin isolated from Pleurospermum kamtschaticum HOFFMANN (Umbelliferae), is known to have potent anti-inflammatory activity and cytotoxicity against diverse cancer cell lines. In the present study, we attempted to verify whether BS-IV could inhibit cell growth, and induce cell cycle arrest and apoptosis in highly invasive YD-10B human oral s...

background: coverage of the bronchial stumps (bss) with adjacent tissues can improve healing and reduce bronchial complications in complex thoracic surgery. there is no evidence for the application of human amnion allograft for prevention of air leak from the bs. the comparison of the amniotic membrane (am) and pleural patch for bs healing after lobectomy in dogs was our aim in this study. mate...

Wireless Sensor Networks (WSNs) often serve mission-critical applications in hostile environments and may be thus a subject to attacks. Since the sensor data are collected at in situ base-station (BS), an adversary can inflict the maximal damage to a WSN by pinpointing the BS. In this paper, we propose three novel approaches for boosting the anonymity of the BS nodes to protect them from potent...

The predictions for the Bs,d − B̄s,d mixing mass differences ∆Ms,d and the branching ratios Br(Bs,d → μμ̄) within the Standard Model (SM) and its extensions suffer from considerable hadronic uncertainties present in theBs,d-meson decay constants FBs,d that enter these quantities quadratically. We point out that in the restricted class of models with minimal flavour violation (MFV) in which only t...

Biosurfactants (BSs) are "green" amphiphilic molecules produced by microorganisms during biodegradation, increasing the bioavailability of organic pollutants. In this work, the BS production yield of marine hydrocarbon degraders isolated from Elefsina bay in Eastern Mediterranean Sea has been investigated. The drop collapse test was used as a preliminary screening test to confirm BS producing s...

This paper develops a comprehensive new approach to the modeling and analysis of heterogeneous cellular networks (HetNets) that accurately incorporates correlation in the locations of users and base stations, which exists due to the deployment of small cell base stations (SBSs) at the places of high user density (termed user hotspots in this paper). Modeling the locations of the geographical ce...

The migration of UMTS carrier frequencies to the 2 GHz band has stimulated interest in radio coverage in urban environments. This paper examines the problem of poor signal quality close to buildings. It uses simulation based on approximate propagation models in a “generic” urban environment to estimate the relationship between size of coverage black spots and distance from the serving BS. Consi...

An introduction and step-by-step guide to the calculation of branch support (BS) and partitioned branch support (PBS) is provided, along with a new summary measure of conflict among data partitions, the partition congruence index (PCI). Patterns of PCI vs. BS are compared for two data matrices from butterflies. PCI is a close mirror of BS unless BY is relatively low and there is a lot of confli...

Data gathering in wireless sensor networks (WSN) consumes more energy due to large amount of data transmitted. In direct transmission (DT) method, each node has to transmit its generated data to the base station (BS) which leads to higher energy consumption and affects the lifetime of the network. Clustering is one of the efficient ways of data gathering in WSN. There are various kinds of clust...
