Pseudo Goldstone Bosons Phenomenology in Minimal Walking Technicolor

We construct the non-linear realized Lagrangian for the Goldstone Bosons associated to the breaking pattern of SU(4) to SO(4). This pattern is expected to occur in any Technicolor extension of the standard model featuring two Dirac fermions transforming according to real representations of the underlying gauge group. We concentrate on the Minimal Walking Technicolor quantum number assignments with respect to the standard model symmetries. We demonstrate that for, any choice of the quantum numbers, consistent with gauge and Witten anomalies the spectrum of the pseudo Goldstone Bosons contains electrically doubly charged states which can be discovered at the Large Hadron Collider.Comment: 25 pages, 5 figure

La mutualità nel caregiving: una revisione della letteratura

Mutuality, considered the feeling of intimacy and the positive relationship between a caregiver and a arereceiver, is gaining an increasing interest in the international research arena, on the light of the socio-demographic changes and the increase in chronic degenerative diseases. The purpose of this article is to make a critical analysis of the literature on mutuality in order to identify its predictors and outcomes. A literature review was performed with the following databases: PubMed, CINAHL, PsycInfo, ASSIA and Pciological Abstract. Twenty articles were selected. From the critical analysis of the literature mutuality emerges as key variable in the process of caregiving and in the mental and physical health of the caregiver and carereceiver. In caregivers, high levels of mutuality are associated with less stress, depression and burden and a better quality of life and perceived health; in patients, high mutuality improves the recovery process from an illness, reduces anxiety and depression and improves the quality of life. Future studies aimed at the study of this variable also in the Italian population could support the development of programs to improve the quality of life of caregivers and carereceiver

A cryogenic waveplate rotator for polarimetry at mm and sub-mm wavelengths

Mm and sub-mm waves polarimetry is the new frontier of research in Cosmic Microwave Background and Interstellar Dust studies. Polarimeters working in the IR to MM range need to be operated at cryogenic temperatures, to limit the systematic effects related to the emission of the polarization analyzer. In this paper we study the effect of the temperature of the different components of a waveplate polarimeter, and describe a system able to rotate, in a completely automated way, a birefringent crystal at 4K. We simulate the main systematic effects related to the temperature and non-ideality of the optical components in a Stokes polarimeter. To limit these effects, a cryogenic implementation of the polarimeter is mandatory. In our system, the rotation produced by a step motor, running at room temperature, is transmitted down to cryogenic temperatures by means of a long shaft and gears running on custom cryogenic bearings. Our system is able to rotate, in a completely automated way, a birefringent crystal at 4K, dissipating only a few mW in the cold environment. A readout system based on optical fibers allows to control the rotation of the crystal to better than 0.1{\deg}. This device fulfills the stringent requirements for operation in cryogenic space experiments, like the forthcoming PILOT, BOOMERanG and LSPE.Comment: Submitted to Astronomy and Astrophysics. v1: 10 pages, 8 figures. v2: corrected labels for the bibliographic references (no changes in the bibliography). v3: revised version. 9 pages, 7 figures. Added a new figure. Updated with a more realistic simulation for the interstellar dust and with the latest cryogenic test

STEVENALTICA, A NEW GENUS OF MOSS AND LEAF-LITTER INHABITING FLEA BEETLES FROM BOLIVIA (COLEOPTERA: CHRYSOMELIDAE: GALERUCINAE: ALTICINI).

A new genus, Stevenaltica, with two new species, S. normi and S. erronis, from Bolivia is described and illustrated. It is similar to Exoceras Jacoby. An identification key for all flea beetle genera known to occur in mosses in the Western Hemisphere is provided

Dietary Strategies for Management of Metabolic Syndrome: Role of Gut Microbiota Metabolites

Metabolic syndrome (MetS) is a complex pathophysiological state with incidence similar to that of a global epidemic and represents a risk factor for the onset of chronic non-communicable degenerative diseases (NCDDs), including cardiovascular disease (CVD), type 2 diabetes mellitus, chronic kidney disease, and some types of cancer. A plethora of literature data suggest the potential role of gut microbiota in interfering with the host metabolism, thus influencing several MetS risk factors. Perturbation of the gut microbiota's composition and activity, a condition known as dysbiosis, is involved in the etiopathogenesis of multiple chronic diseases. Recent studies have shown that some micro-organism-derived metabolites (including trimethylamine N-oxide (TMAO), lipopolysaccharide (LPS) of Gram-negative bacteria, indoxyl sulfate and p-cresol sulfate) induce subclinical inflammatory processes involved in MetS. Gut microbiota's taxonomic species or abundance are modified by many factors, including diet, lifestyle and medications. The main purpose of this review is to highlight the correlation between different dietary strategies and changes in gut microbiota metabolites. We mainly focus on the validity/inadequacy of specific dietary patterns to reduce inflammatory processes, including leaky gut and subsequent endotoxemia. We also describe the chance of probiotic supplementation to interact with the immune system and limit negative consequences associated with MetS

Manufacturing the creative city: Symbols and politics of Amsterdam North

Experimentation and urban innovation are becoming central references in the discourses of local politicians and urban policymakers aiming to trigger spatial change in times of austerity. Emerging electoral parties and political groups frequently make use of symbolic references to advocate new urban agendas, especially when urban change has high socio-political impacts. This paper explores the relation between political change and spatial interventions by examining how symbols are used to carry out post-industrial urban development. Amsterdam North, once a historical stronghold of the Labor electorate, is today the living laboratory for liberal-progressive parties. Despite initial political dissent against transformation in the area, the planning approach employed in the redevelopment of North currently inspires a new urban agenda for the city. Looking at symbolic acts, languages and objects, we explain how this political change was conveyed through symbols that link past images of manufacturing industry and human labor to emerging narratives of creative urbanism and entrepreneurialism

Bluetongue disease

Bluetongue (BT) is a noncontagious OIE-listed disease of domestic and wild ruminants caused by a virus (Bluetongue virus—BTV) of the Orbivirus genus within the family Reoviridae and transmitted by biting midges of the genus Culicoides. BT is a considerable socioeconomic concern and of major importance for the international trade of animals and animal products. In the past, BT endemic areas were considered those between latitudes 40 °N and 35 °S; however, BT has spread far beyond this traditional range. BTV has multiple serotypes and these serotypes exist in a complex network of serological cross-relationships, varying from partial to no protection between heterologous strains. This chapter summarizes several aspects of BT and BTV with particular emphasis for BTV epidemiology in Sahelian Africa
