Cloud services (CCS) are a crucial element in the service sector, but there are still challenges left in their design, implementation, operation and dismissal, due to issues such as the integration of physical and technical components, interaction of social and technical aspects, dynamic and elastic reconfiguration. In modelling service systems, ontologies have been recognized as a useful instr...

Since the discovery of the top quark in 1995 at the Fermilab Tevatron collider, top quark properties have been measured with ever higher precision. The increase in data has provided the opportunity to probe many new aspects of the top quark sector. In addition to an updated measurement of the helicity of the W boson in t ¯ t events using 5.4 fb −1 , this review briefs three new analyses perform...

The ΛN − ΣN coupling in Λ–hypernuclei and ΛΛ − ΞN coupling in ΛΛ– hypernuclei produce novel physics not observed in the conventional, nonstrange sector. Effects of Λ ↔ Σ conversion in ΛH are reviewed. The role of ΛN − ΣN coupling suppression in the A = 4, 5 Λ–hypernuclei due to Pauli blocking is highlighted, and the implications for the structure of 10 ΛB are explored. Suppression of ΛΛ − ΞN co...

The stability and L2 performance analysis of systems consisting of an interconnection of a linear-time-invariant (LTI) system and a static nonlinear element which is Lipschitz, slope restricted and sector bounded is revisited. The main thrust of the paper is to improve and extend an existing result in the literature to enable (i) concise and correct conditions for asymptotic stability of the in...

Besides those durational differences due to the binary quantity opposition in both vowels and consonants, there are many systematic effects on segment durations within the domain of accentual F0 movement in Finnish. Some such effects are shown in this paper, and it is argued that their motivation is to contribute to a uniform realisation of accent irrespective of segmental word structure.

External finance is critical for less established entrepreneurs, so poor investor protection can hinder competition. We model how lobbying for weaker investor protection reduces access to finance and decreases competition in countries where politicians are less accountable to voters. Weaker accountability thus produces a smaller economic elite. As empirical support for this result, in a broad p...

Introduction Partnerships can vary in size, the nature of the parties involved, and the scope of their work. But at their core, partnerships share some fundamental elements. In the philanthropic world, partnerships are usually voluntary and bring together parties with mutual goals and some level of shared responsibility. Some foundations have partnered with other private philanthropies as well ...

So far the main body of the asset pricing literature has computed liquidity risk premia for either markets or single assets. The vast majority of these studies have been focused on fairly liquid assets, but recently a greater attempt to price such an important component of the asset pricing factors in markets with high illiquidity (especially in real estate) has also started to take place. The ...
