Closedness properties in team learning of recursive functions

1997

This paper investigates closedness properties in relation with team learning of total recursive functions. One of the first problems solved for any new identification types is the following: “Does the identifiability of classes U1 and U2 imply the identifiability of U1∪U2?” In this paper we are interested in a more general question: “Does the identifiability of every union of n−1 classes out of U1,...,Un imply the identifiability of U1∪...∪Un?” If the answer is positive, we call such identification type n-closed. We show that n-closedness can be equivalently formulated in terms of team learning. After that we find for which n team identification in the limit and team finite identification t…

The Development of Novel Approaches to the Identification of Chemical and Protein Respiratory Allergens

2008

In October 2006, the European Centre for theValidation of Alternative Methods (ECVAM) spon-sored and hosted a three-day workshop to consideropportunities and challenges in the development ofalternative methods for the identification and char-acterisation of chemical respiratory allergens. Theproceedings, conclusions and recommendations ofthat workshop were subsequently made available asECVAM Workshop Report 60 (1).In April 2008, a second meeting was convenedby ECVAM to consider what progress has beenmade in the light of the recommendations derivedfrom the 2006 Workshop and the publishedreport. This meeting had as a second objective —to consider whether new opportunities for theidentificatio…

Identification of fish species by reversed-phase high-performance liquid chromatography with photodiode-array detection

1998

A method for the separation of sarcoplasmic fish proteins by RP-HPLC is described. The procedure revealed significant differences useful for reliable identification of fish species. Sixteen of the most common Finnish freshwater fish species were differentiated by species-specific HPLC chromatograms obtained using photodiode-array detection (PAD) at 200-350 nm. The analytical column was a Hi-Pore RP-304 reversed-phase column. The separation was performed by a linear gradient of acetonitrile and water with a small amount of trifluoracetic acid (TFA). Star-symbol plots were constructed from the chromatograms to visualize the data. Clearly different HPLC protein profiles for most fish species w…

QuBiLs-MAS method in early drug discovery and rational drug identification of antifungal agents

2015

The QuBiLs-MAS approach is used for the in silico modelling of the antifungal activity of organic molecules. To this effect, non-stochastic (NS) and simple-stochastic (SS) atom-based quadratic indices are used to codify chemical information for a comprehensive dataset of 2478 compounds having a great structural variability, with 1087 of them being antifungal agents, covering the broadest antifungal mechanisms of action known so far. The NS and SS index-based antifungal activity classification models obtained using linear discriminant analysis (LDA) yield correct classification percentages of 90.73% and 92.47%, respectively, for the training set. Additionally, these models are able to correc…

Identification of Immunoreactive Viral Proteins

2003

Several diagnostic tools are available for the identification of acute and latent viral infections. Although newly developed nucleic acid amplification methods, such as the polymerase chain reaction (PCR), have proved to be very useful diagnostic procedures, conventional methods, such as cell culture and serology, still play an important role in viral diagnostics. Despite the fact that modern serological assays, such as enzyme-linked immunosorbent assay (ELISA), are inexpensive and easy to perform, there is a strong demand to improve the performance of such systems. Most serological tests are based on poorly characterized antigens produced in infected culture cells. It has been shown, howev…

Identification of stiffness,dissipation and input parameters of randomly excited non-linear systems: Capability of restricted potential models (RPM)

2006

Abstract A dynamic identification technique in the time domain for time invariant systems under random external forces is presented. This technique is based on the use of the class of restricted potential models (RPM), which are characterized by a non-linear stiffness and a special form of damping, that is a product of the input power spectral density (PSD) matrix and the velocity gradient of a non-linear function of the total mechanical energy. By applying It o ^ stochastic differential calculus and by specific analytical manipulations, some algebraic equations, depending on the response statistics and on the mechanic parameters that characterize RPM, are obtained. These equations can be u…

Impulsive Tests on Historical Structures: The Dome of Teatro Massimo in Palermo

2016

Cultural heritage is the set of things, that having particular historical cultural and aesthetic are of public interest and constitute the wealth and civilization of a place and its people. Sharpen up methodologies aimed at safeguarding of monuments is crucial because the future may have in mind the historical past. Italy is a country that has invested heavily on its historical memory returned in large part by the historical building or the monuments. Furthermore, culture represents a fundamental indicator of the growth of the culture of a country. Consider a monitoring project of one of the most Impressive theater in the world, like “Teatro Massimo” in Palermo (Italy), means to add value t…

Advances in the knowledge of South African Riella (Sphaerocarpales) and a new endemic species, Riella trigonospora

2014

Cultures of soil sediments collected in June 2012 from saltpans and vleis from five South African localities have revealed two new, geographically distant, populations of the endemic Riella alatospora, confirmed the presence of Riella purpureospora from Blouvlei in the Cape Town area and uncovered a new endemic species, Riella trigonospora. The new species obtained from cultures from five sampled localities is described and illustrated. It is dioicous and characterised by acuminate to rostrate, papillose involucres and by a unique spore morphology. The spores are dark purple, as in R. purpureospora, and have an irregular discontinuous wing at the equatorial plane, which suggests a morpholog…
