The discrimination problem for two ground states or two thermal states of the quantum Ising model

We address the one-dimensional quantum Ising model as an example of system exhibiting criticality and study in some details the discrimination problem for pairs of states corresponding to different values of the coupling constant. We evaluate the error probability for single-copy discrimination, the Chernoff bound for $n$-copy discrimination in the asymptotic limit, and the Chernoff metric for the discrimination of infinitesimally close states. We point out scaling properties of the above quantities, and derive the external field optimizing state discrimination for short chains as well as in the thermodynamical limit, thus assessing criticality as a resource for quantum discrimination in many-body systems.Comment: revised version, title changed, 4 fig

Cyclic Permutations in Kazama-Suzuki String Models

Moddings by cyclic permutation symmetries are performed in 4-dimensional strings, built up from N=2 coset models of the type $CP_m=SU(m+1)/SU(m)\times U(1)$. For some exemplifying cases, the massless chiral and antichiral states of $E_6$ are computed. The extent of the equivalence between different conformal invariant theories which possess equal chiral rings is analyzed.Comment: 26 pages, LaTex fil

Zebrafish as animal model for aquaculture nutrition research.

The aquaculture industry continues to promote the diversification of ingredients used in aquafeed in order to achieve a more sustainable aquaculture production system. The evaluation of large numbers of diets in aquaculture species is costly and requires time-consuming trials in some species. In contrast, zebrafish (Danio rerio) can solve these drawbacks as an experimental model, and represents an ideal organism to carry out preliminary evaluation of diets. In addition, zebrafish has a sequenced genome allowing the efficient utilization of new technologies, such as RNA-sequencing and genotyping platforms to study the molecular mechanisms that underlie the organism's response to nutrients. Also, biotechnological tools like transgenic lines with fluorescently labeled neutrophils that allow the evaluation of the immune response in vivo, are readily available in this species. Thus, zebrafish provides an attractive platform for testing many ingredients to select those with the highest potential of success in aquaculture. In this perspective article aspects related to diet evaluation in which zebrafish can make important contributions to nutritional genomics and nutritional immunity are discussed

URBAN COMFORT IN BUCHAREST.SOCIAL-ECONOMIC PARAMETERS

The undergoing concerns for local and regional development focus also on the territorial analyses. The local socio-economic analysis is naturally followed by the strategic planning of development during which the local public authorities initiate and organize, locally, the economic development of the respective territorial unit. This article is intended to analyze a concrete case, that of the Capital City of Romania, the Municipality of Bucharest. One of Romania’s objectives is to sensitize and educate the civil society, the private organizations and the public authorities towards understanding and observing the urban landscape. In the spirit of the aspects mentioned above, the authors have presented a case study, at the end of this article, in which the reconsideration of the urban architectural framework matches perfectly with the wish of introducing elements of spatial dynamics and of balance. In this spirit, the over-crowded City of Bucharest, which has a density of 9009 inhabitants/sq.km, will potentially be turned into an oasis of social comfort that will positively influence the urban organism.local economic development, urban comfort, Bucharest

Using Regression Discontinuity Design to Identify the Effect of Zoning

We test the effect of minimum lot zoning on rural-to-urban land use conversion using Regression Discontinuity Design (RDD), a technique that exploits natural discontinuities in the data to identify causal effects. Observations are drawn from either size of a discontinuous minimum lot size zoning boundary. Using these selected sub-samples, a binary discrete choice model of residential land use change is estimated using parcel-level data and other spatially explicit data from an exurban county that lies on the fringes of Cleveland, Ohio. Results show that controlling for unobserved correlation in the data clearly identifies a negative and significant effect of larger minimum lot size zoning on the probability of conversion to a residential use.Land Economics/Use,

A new family, Coryphoridae (Ephemeroptera: Ephemerelloidea), and description of the winged and egg stages of Coryphorus

A new family Coryphoridae is proposed in the superfamily Ephemerelloidea for the monotypic genus Coryphorus. Characters that distinguish Coryphoridae from all other Ephemerelloidea are discussed. The male imago, male subimago, female imago, and egg of Coryphorus aquilus Peters are described for the first time.Se propone a Coryphoridae como una nueva familia de Ephemerelloidea para el genero monotipico Coryphorus. Se discuten los caracteres que distinguen a Coryphoridae del resto de los Ephemerelloidea. Se describen por primera vez el imago macho, subimago macho, imago hembra y huevo de Coryphorus aquilus Peters
