Reciprocity of gauge operators in N=4 SYM

A recently discovered generalized Gribov-Lipatov reciprocity holds for the anomalous dimensions of various twist operators in N=4 SYM. Here, we consider a class of scaling psu(2,2|4) operators that reduce at one-loop to twist-3 maximal helicity gluonic operators. We extract from the asymptotic long-range Bethe Ansatz a closed expression for the spin dependent anomalous dimension at four loop order and provide a complete proof of reciprocity. We comment about the interplay with possible, yet unknown, wrapping corrections.Comment: Latex, JHEP style, 36 pages, v2: references adde

ELECTROTHERAPY IN THE TREATMENT OF PATIENTS AFFECTED BY RABIES: EXPERIMENTS CONDUCTED AT THE “MAGGIORE” HOSPITAL OF MILAN IN 1865

During the nineteenth century, the scientific context of rabies treatment was weak due to the lack of the literature on specific nosology of the rabies disease, and unspecific and ineffective therapy approaches. Electrotherapy already represented an important therapeutic approach for nervous system diseases, although not specifically for rabies. In the present paper, the authors discuss the use of electrotherapy in the treatment of humans affected by rabies in an experimental study conducted at the Maggiore Hospital of Milan, with the aim of establishing the discovery of a possible specific therapy. By analyzing the printed scientific sources available in the Braidense Library of Milan, the authors describe four experiments conducted on patients of different ages. Symptoms and effects both during and after the electrotherapy are also highlighted. The experiments demonstrated that electricity is not an effective therapy in the treatment of rabies, being rather able to cause serious functional and organic alterations in all the patients. Analyzing the Milanese experiments, the authors reported specific Italian history of a scientific and medical approach to rabies at the end of the 18th century, which led to the promotion of health education, reinforced prevention strategies and opened the way to the vaccination era

Neural networks for classification of strokes in electrical impedance tomography on a 3D head model

We consider the problem of the detection of brain hemorrhages from three dimensional (3D) electrical impedance tomography (EIT) measurements. This is a condition requiring urgent treatment for which EIT might provide a portable and quick diagnosis. We employ two neural network architectures -- a fully connected and a convolutional one -- for the classification of hemorrhagic and ischemic strokes. The networks are trained on a dataset with $40\,000$ samples of synthetic electrode measurements generated with the complete electrode model on realistic heads with a 3-layer structure. We consider changes in head anatomy and layers, electrode position, measurement noise and conductivity values. We then test the networks on several datasets of unseen EIT data, with more complex stroke modeling (different shapes and volumes), higher levels of noise and different amounts of electrode misplacement. On most test datasets we achieve $\geq 90\%$ average accuracy with fully connected neural networks, while the convolutional ones display an average accuracy $\geq 80\%$. Despite the use of simple neural network architectures, the results obtained are very promising and motivate the applications of EIT-based classification methods on real phantoms and ultimately on human patients.Comment: 17 pages, 11 figure

The Contribution of Volatile Organic Compounds (VOCs) Emitted by Petals and Pollen to the Scent of Garden Roses

Flower scent is an important trait of ornamental roses and has been an important character in the selection processes. In the present study, the composition of the volatile organic compounds (VOCs) emitted by both petals and pollen of 21 garden roses (Chinensis, Climber, English rose, Floribunda, Hybrid Tea, Multiflora, Damascena, Musk rose, Polyantha, Rugosa and Shrub) was investigated through the GC-MS Static Headspace method. A total of 19 different VOCs were detected, and for each identified compound, an odorant description was included. In petals, the most common VOCs were 2-phenylethanol, methyl eugenol, and hexanal, present in 95%, 86% and 86% of garden roses, respectively. While, in pollen were methyl eugenol, methyl-1-butanol, and hexanal (present in 100%, 95%, and 90% of the genotypes, respectively), even if in lower content. The comparison between the petals and pollen profile shown that, even with less quantity, the main compounds characterizing the scent of the studied roses are present both in the petals and in the pollen (19 and 17 compounds, respectively), with different magnitude. Overall, the content of VOCs emitted by petals was more than five times higher than that produced by pollen. Different and characteristic VOCs profiles were emitted by petals and pollen of the studied garden roses

The aging process and potential interventions to extend life expectancy

Aging is commonly defined as the accumulation of diverse deleterious changes occurring in cells and tissues with advancing age that are responsible for the increased risk of disease and death. The major theories of aging are all specific of a particular cause of aging, providing useful and important insights for the understanding of age-related physiological changes. However, a global view of them is needed when debating of a process which is still obscure in some of its aspects. In this context, the search for a single cause of aging has recently been replaced by the view of aging as an extremely complex, multifactorial process. Therefore, the different theories of aging should not be considered as mutually exclusive, but complementary of others in the explanation of some or all the features of the normal aging process. To date, no convincing evidence showing the administration of existing “anti-aging” remedies can slow aging or increase longevity in humans is available. Nevertheless, several studies on animal models have shown that aging rates and life expectancy can be modified. The present review provides an overlook of the most commonly accepted theories of aging, providing current evidence of those interventions aimed at modifying the aging process

Technology park in connection with national filing of radioactive waste

The starting project idea arises from the need to provide a national disposal for radioactive waste as required by the European Union, in order to adjust Italy to the rest of the other European countries. The site will replace the temporary disposals realized near to the four former nuclear plants in the Italian territory, to permit plants decommissioning and the subsequent environmental rehabilitation of those areas. The disposal will be realized according to the most modern standards of environmental safety and ensuring maximum sustainability of the site thus using all the ‘Best Available Technique’ for the construction of Near Zero Energy Buildings and energy production systems from renewable sources. The Project is based on data coming from SOGIN (the Italian society for the decommissioning of nuclear plants) for the national radioactive waste disposal able to contain 90,000 cubic meters of radioactive waste and divided into two parts, allowing separate storage of the waste of first and second level, respectively, in quantities of 15.000 mc and 75.000 mc. The Technology Park close to the disposal, will be done with maximum transparency criteria, so to make the site not only accessible to citizens, but even a tourist attraction and a meeting area for the scholars, university students and researchers. In this technological park there are strong requirements for high security systems and an adequate transport and mobility plan designed even for critical situations. In fact in the designed Park there are even special protection systems from physical agents with the possibility, in case of danger, of an access to the closed collection points that are able to insulate workers and visitors from fire or radiation danger
