D-Glucose as a Pentavalent Chiral Scaffold
2003
A novel carbohydrate-based scaffold for combinatorial chemistry has been developed. This scaffold allows the selective attachment of five different side chains, giving rise to products of enormous structural diversity. As a demonstration of its usefulness, a series of model compounds has been prepared in high purity and yield by multistep parallel synthesis on a solid phase. (© Wiley-VCH Verlag GmbH & Co.

An ergodic wideband MIMO channel simulator based on the geometrical T-junction scattering model for vehicle-to-vehicle communications
2010
In this paper, a wideband multiple-input multiple-output (MIMO) simulation model for vehicle-to-vehicle (V2V) channels in T-junction propagation environments is proposed. This simulation model takes the exact relationship between the angle-of-arrival (AOA) and the angle-of-departure (AOD) into account. In order to determine the parameters of the simulation model, the Riemann sum method (RSM) is applied. Furthermore, the statistical and ergodic properties of the simulation model are studied. Closed-form solutions are derived for the space-time-frequency cross-correlation function (STF-CCF), the two-dimensional (2D) spatial cross-correlation function (CCF), the temporal autocorrelation functi…
An adaptive multimeme algorithm for designing HIV multidrug therapies.
2007
This paper proposes a period representation for modeling the multidrug HIV therapies and an Adaptive Multimeme Algorithm (AMmA) for designing the optimal therapy. The period representation offers benefits in terms of flexibility and reduction in dimensionality compared to the binary representation. The AMmA is a memetic algorithm which employs a list of three local searchers adaptively activated by an evolutionary framework. These local searchers, having different features according to the exploration logic and the pivot rule, have the role of exploring the decision space from different and complementary perspectives and, thus, assisting the standard evolutionary operators in the optimizati…

Unconventional ligands and modulators of nicotinic receptors
2002
Evidence gathered from epidemiologic and behavioral studies have indicated that neuronal nicotinic receptors (nAChRs) are intimately involved in the pathogenesis of a number of neurologic disorders, including Alzheimer's disease, Parkinson's disease, and schizophrenia. In the mammalian brain, neuronal nAChRs, in addition to mediating fast synaptic transmission, modulate fast synaptic transmission mediated by the major excitatory and inhibitory neurotransmitters glutamate and GABA, respectively. Of major interest, however, is the fact that the activity of the different subtypes of neuronal nAChR is also subject to modulation by substances of endogenous origin such as choline, the tryptophan …
The recruitment of scallops (and beyond) by two different artificial collectors (Gulf of Taranto, Mediterranean Sea)
2015
This study provides for the first time an evaluation of the natural availability of scallop seeds along the coastal area of Taranto (Mediterranean Sea, Southern Italy). To select the best artificial collectors to harvest scallop seeds in this area, cylindrical collectors (Cyl) were compared to traditional 'Japanese-style onion bags' (Bag) across three sites. Scallops represented 26.6% of total bivalve recruitment among all collectors (782 ± 331 ind. m-2). The most recruited scallops were Flexopecten glaber and Mimachlamys varia. The white (F. glaber) and black scallops (M. varia) were abundant at all three sites, while the queen scallop, Aequipecten opercularis, was only found at one site. …
Advances in Research for Biomimetic Materials
2018
Smart surfaces and materials can play a significant role in intelligent, adaptive and responsive envelopes because of these intrinsic properties. The environmental question and energy efficiency in which the construction sector is involved, is in a process that can not be interrupted and that puts researchers and designers in front of a scientific and design challenge in which it is necessary to contribute to find different ways of study and experimentation on new materials and constructive languages, ranging from the application, to the structural, design and molecular, to mention the main ones. The development of technologies is helping architects of the “biomimetic current” to recreate c…
Innovative Applications and Experiments for the Protection of Archaeological Sites
2020
Nowadays, the protection in situ, the enhancement and the fruition of archaeological sites are issues that are even more relevant, if we take into account the effects caused, in recent decades, by climate change both on the conservation of the most fragile artefacts and on the well-being of visitors. New questions related to the ‘recover of identity’ are raised by the relationships that the protection interventions establish with the environmental context (external) and with the ancient ruins (internal), imposing an interpretation of the project as a union of landscape, morphological, climatic, technical, use and management aspects, or by requiring a holistic and integrated approach, from a…
Astrazione e mimesi nella rappresentazione digitale
2013
La rappresentazione piana si è espressa, da sempre, per mezzo di registri oscillanti tra forme espressive mimetiche e forme astratte. A ben vedere sembrerebbe che la comunicazione, in questo come in altri campi, insegua, da un lato, la necessità dell’uomo di riprodurre il mondo conosciuto imitandone le caratteristiche, dall’altro, di comporre il sintagma espressivo in modo da comunicare concetti, idee, senza cercare di riprodurre il mondo reale, ma con la volontà di trasmettere un pensiero. Non è corretto, però, pensare che la separazione tra il codice mimetico e quello astratto e simbolico sia sempre così evidente. IL saggio vuole dimostrare come anche la rappresentazione digitale si muova…
