We solve the entanglement classification under stochastic local operations and classical communication (SLOCC) for all multipartite symmetric states in the general N-qubit case. For this purpose, we introduce 2 parameters playing a crucial role, namely, the diversity degree and the degeneracy configuration of a symmetric state. Those parameters give rise to a simple method of identifying operational families of SLOCC entanglement classes of all symmetric N-qubit states, where the number of families grows as the partition function of the number of qubits.

For modal analysis of large structures, it is unpractical and expensive to use artificial excitation (e.g., shakers). However, engineering structures are most often subject to ambient loads (e.g., traffic and wind) that can be exploited for modal parameter estimation. One difficulty is that the actual loading conditions cannot generally be measured, and output-only measurements are available. This paper proposes to explore the utility of blind source separation (BSS) techniques for operational modal analysis. The basic idea of BSS is to recover unobserved source signals from their observed mixtures. The feasibility and practicality of the proposed method are demonstrated using an experimental application.

We present experimental schemes that allow us to study the entanglement classes of all symmetric states in multiqubit photonic systems. We compare the efficiency of the proposed schemes and highlight the relation between the entanglement properties of symmetric Dicke states and a recently proposed entanglement scheme for atoms. In analogy to the latter, we obtain a one-to-one correspondence between well-defined sets of experimental parameters and multiqubit entanglement classes inside the symmetric subspace of the photonic system.

By examining stock market reactions to the announcement of operational losses by financial companies, this paper attempts to disentangle operational losses from reputational damage. Our analysis deals with 154 events coming from the FIRST database of OpVantage. Events occurred between 1990 and 2004 in companies belonging to the financial sector and that are listed on the major European and US Stock Exchanges. Results show significant, negative abnormal returns at the announcement date of the loss, along with an increase in the volumes of trade. In cases of internal fraud, the loss in market value is greater that the operational loss amount announced, which is interpreted as a sign of reputational damage. Negative impact is proportionally greater when the loss amount represents a larger share in the company’s net profit. [less ▲]

Field experiments were conducted in 2010 to investigate the effect of fungicide commercial formulation, timing and dosages on the severity of these two diseases in winter wheat in Luxembourg. Different types of fungicides and fungicide combinations containing active ingredients such as triazoles and strobilurins were used in field trials including susceptible cultivars to Septoria leaf blotch (SLB, caused by Septoria tritici) and wheat leaf rust (WLR, caused by Puccinia triticina). The three formulations of fungicides tested were: (i) a mix of triazole and amine (Prothioconazole 250 g/l + Spiroxamine 500 g/l) associated with chlorothalonil 500 g/l, (ii) sole strobilurin (Azoxystrobine 250 g/l), and (iii) a mix of strobilurin and triazole (Epoxiconazole 125 g/l; Azoxystrobine 250 g/l). The optimum time of fungicide spray was assessed through the mechanistic model PROCULTURE and a stochastic model based on night favourable weather conditions conducive to WLR development. The results showed that for plots treated with fungicide formulation containing either a triazole or a strobilurin, the grain yield earned was not significantly different from the untreated plots (P > 0.05). Whereas single fungicide treatment involving a mixture of triazole and strobilurin at the optimum time gave an earning (on average 7 dt ha-1) compare to the control and a yield similar to that obtained with the double or triple fungicide treatments.

This paper is dedicated to the identification of the constraints and factors enabling the computation of an effective geographic profile, with the specificity of focusing only on the elements that could be available during an investigation. It aimed at filling the gap between the inductive demarche of environmental criminology and the deductive, operational procedure followed by geographic profilers. It reviews successively the relationship between the premeditation, the seriousness of the facts, the nature of the offences and the spatio-temporal pattern of the crimes with the criteria required to build effective likelihood surfaces in geographic profiling. A decision tree is provided as a tool for evaluating the risks of an ineffective geographic profile with regard to the non-respect of the different conditions. [less ▲]
