Ad hoc sensor networks consist of large number of wireless sensors that communicate with each other in the absence of a xed infrastructure. Fast self-recon guration and power e ciency are very important property on any sensor network management. The clustering problem consists in partitioning network nodes into groups called clusters, thus giving at the network a hierarchical organization. Clus...

We report a D4h@Dy single-molecule magnet (SMM) with Ueff energy barrier of 1565 K, one the highest barriers for any 6-coordinate lanthanide SMM.

Materials and methods: Th e eff ects of HBO on Leishmania tropica promastigote and amastigote forms were studied at a pressure of 2.5 atmosphere absolute (ata). We examined the cytotoxic eff ect of HBO on promastigotes using the trypan blue exclusion test and the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) dye-reduction assay. To investigate the eff ects of HBO treatment ...

To each game form g an effectivity function (EFF) Eg can be naturally assigned. An EFF E will be called formal (respectively, formal-minor) if E = Eg (respectively, E ≤ Eg) for a game form g. (i) An EFF is formal if and only if is superadditive and monotone. (ii) An EFF is formal-minor if and only if it is weakly superadditive. Theorem (ii) looks more sophisticated, yet, it is simpler and instr...

The Fukushima Daiichi accident in Japan in March 2011 caused a fundamental change in Germany’s energy policy which led to the immediate shut down of nearly half of its nuclear power plants. This paper uses data from Germany’s largest internet platform for real estate to investigate the eff ect of Fukushima on the German housing market. Using a diff erence-in-diff erences approach, we fi nd that...

Absolute magnitudes of the effective nonlinearity, deff, were measured for seven KTP and six BBO crystals. The d(eff), were derived from the parametric gain of an 800-nm signal wave in the sample crystals when they were pumped by the frequency-doubled, spatially filtered light from an injectionseeded, Q-switched Nd:YAG laser. The KTP crystals, all type II phase matched with propagation in the X...

This paper proposes a variant of the classical HAUSMAN specifi cation test commonly employed to decide whether the estimation of a random-eff ects model is a viable alternative to estimating fi xed eff ects. Whereas the classical test probes the equality of fi xedand random eff ects, the proposed variant focuses on the equality of between-groups and fi xed-eff ects coeffi cients. While both tes...

Two-body charmless nonleptonic decays of Bu and Bd mesons are studied within the framework of generalized factorization in which the effective Wilson coefficients ceff i are renormalization-scale and -scheme independent while factorization is applied to the tree-level hadronic matrix elements. Contrary to previous studies, our ceff i do not suffer from gauge and infrared problems. Nonfactorizab...

Despite the identification of essential processes in which cell fusion plays spectacular roles such as in fertilization and development of muscle, bone, and placenta, there are no identified proteins that directly mediate developmental cell fusion reactions. C. elegans has recently become among the best-characterized models to use for studying developmental cell fusion. The eff-1 (epithelial fu...

Several data forwarding and clustering techniques have been proposed to improve Underwater Wireless Sensor Networks (UWSNs) performance, but void communications, packet collisions, energy efficiency remain unresolved. We introduce a novel routing solution for QoS-efficient transmission from the underwater sensor node surface sink using Swarm Intelligence (SI). The protocol Energy Optimization R...
