An Ordinal Shapley Value for Economic Environments (Revised Version)

We propose a new solution concept to address the problem of sharing a surplus among the agents generating it. The problem is formulated in the preferences-endowments space. The solution is defined recursively, incorporating notions of consistency and fairness and relying on properties satisfied by the Shapley value for Transferable Utility (TU) games. We show a solution exists, and call it the Ordinal Shapley value (OSV). We characterize the OSV using the notion of coalitional dividends, and furthermore show it is monotone and anonymous. Finally, similarly to the weighted Shapely value for TU games, we construct a weighted OSV as well.Non-Transferable utility games, Shapley value, Ordinal Shapley value, consistency, fairness.

Please Lower Small Cell Antenna Heights in 5G

In this paper, we present a new and significant theoretical discovery. If the absolute height difference between base station (BS) antenna and user equipment (UE) antenna is larger than zero, then the network capacity performance in terms of the area spectral efficiency (ASE) will continuously decrease as the BS density increases for ultra-dense (UD) small cell networks (SCNs). This performance behavior has a tremendous impact on the deployment of UD SCNs in the 5th-generation (5G) era. Network operators may invest large amounts of money in deploying more network infrastructure to only obtain an even worse network performance. Our study results reveal that it is a must to lower the SCN BS antenna height to the UE antenna height to fully achieve the capacity gains of UD SCNs in 5G. However, this requires a revolutionized approach of BS architecture and deployment, which is explored in this paper too.Comment: Final version in IEEE: http://ieeexplore.ieee.org/document/7842150/. arXiv admin note: substantial text overlap with arXiv:1608.0669

The grapevine aphid Aphis illinoisensis : a good example of recent invasion and rapid colonization by aphids

Aphis illinoisensis represents one of the most recent aphid invaders from the New World to the Mediterranean Region. This aphid, which is native to North America and is now widely distributed in Central and South America, was first found in Southern Turkey in 2002, and in 2005 it was also found in Crete (Greece). Thereafter it was recorded from Northern Cyprus, Israel, Tunisia, Algeria, Montenegro and Libya, and is now probably present throughout the Mediterranean. The present work provides data on the presence of this aphid in the Maltese islands, a group of low-lying islands situated in the central Mediterranean Basin.peer-reviewe

First field records of the sexuales (males and oviparae) of Toxoptera aurantii (Hemiptera : Aphididae)

Toxoptera aurantii (Boyer de Fonscolombe) is an aphid pest of great agricultural importance, not only due to its polyphagy but mostly due to its ability to transmit various plant viruses e.g. Citrus tristeza virus on Citrus (Blackman & Eastop, 2000). Blackman & Eastop (2000) considered this aphid to be entirely anholocyclic, because no sexual morphs have ever been observed in the field.peer-reviewe

Cinara tujafilina (del Guercio, 1909) - a new aphid record for Malta (Aphididae, Lachninae)

The aphidofauna of the Maltese archipelago is currently composed of some one hundred recorded species (Mifsud & Pérez Hidalgo, 2011; Mifsud et al. 2011) of which only six species are associated with conifers. Of these, three species belong to the genus Cinara: C. maghrebica, C. palaestinensis (both recorded on Pinus halepensis) and C. cupressi (recorded on Cupressus sempervirens). Identification of a recently captured single alate viviparous female of Cinara, based on Binazzi & Scheurer (2009) and Nieto Nafría et al., (2003), proved to be Cinara (Cupressobium) tujafilina (del Guercio, 1909), a species not previously recorded from Malta.peer-reviewe

First report of an adelgid from Malta (Hemiptera, Aphidoidea, Adelgidae)

In recent years, the aphid fauna of the Maltese Islands has received considerable attention. miFSud et al. (2011) reviewed earlier works on the subject and provided information on previously reported species and on several new records. An updated list of aphids provided therein included 98 Aphididae and a single species of Phylloxeridae. The only other family currently included with aphids, the Adelgidae was not represented in the list. Samples of young shoots of Pinus halepensis Mill. were observed infested with a whitish flocculent material in several localities in Malta and examination of this material proved it to belong to an adelgid which we report here underpeer-reviewe

Energy evolution of the moments of the hadron distribution in QCD jets including NNLL resummation and NLO running-coupling corrections

The moments of the single inclusive momentum distribution of hadrons in QCD jets, are studied in the next-to-modified-leading-log approximation (NMLLA) including next-to-leading-order (NLO) corrections to the alpha_s strong coupling. The evolution equations are solved using a distorted Gaussian parametrisation, which successfully reproduces the spectrum of charged hadrons of jets measured in e+e- collisions. The energy dependencies of the maximum peak, multiplicity, width, kurtosis and skewness of the jet hadron distribution are computed analytically. Comparisons of all the existing jet data measured in e+e- collisions in the range sqrt(s)~2-200 GeV to the NMLLA+NLO* predictions allow one to extract a value of the QCD parameter Lambda_QCD, and associated two-loop coupling constant at the Z resonance alpha_s(m_Z^2)= 0.1195 +/- 0.0022, in excellent numerical agreement with the current world average obtained using other methods.Comment: 40 pages, 15 figures.
