Measurements of B Rare Decays at the Tevatron

A summary of recent results on B rare decays from the CDF and D0 experiments operating in Run II of the Fermilab Tevatron is given; analyzed decay modes are B_{d,s}--> hh, B_{d,s}--> mu^{+}mu^{-}, and B--> mu^{+} mu^{-}h. Data samples are relative to 1 fb^{-1} or more integrated luminosity of p-pbar collisions at sqrt(s) = 1.96 TeV. All reported results are in agreement with Standard Model predictions and consistent with B-Factories analyzes.Comment: Proceedings of the Moriond QCD and Hdronic Interactions 2007 Conference, La Thuile, March 17-24, 200

TERRITORI EMPIRICI. COMUNICARE L'IDENTITÀ DEI LUOGHI: UN PROGETTO DI DESIGN DELLA COMUNICAZIONE

Territori empirici è il progetto di un format crossmediale per sistemi di guida al territorio, inserito nel contesto della ricerca del Design della Comunicazione per l'identità territoriale. Orientato a un turismo di tipo esperienziale, indaga soluzioni comunicative atte a rappresentare l'identità profonda dei luoghi e a incentivarne la pratica, per restituire valore conoscitivo all'esperienza in loco. Modello comunicativo applicabile a tutte le realtà territoriali non turistiche, sfrutta elementi percettivi e di linguaggio per far emergere il 'senso' del territorio

Communication design for accessing cultural landscape - Design de Comunicação para o acesso à paisagem cultural

Nowadays the relationship between people, culture and territories is changing. On the one hand, great emphasis is placed on the value of cultural heritage and local identity as means for social cohesion and economic growth. On the other hand, experience-based tourism is growing and, consequently, it increases the need of an experience-based communication strategy. This paper explores the contribution of communication design to tourism promotion and the enhancement of cultural identity. It will deal with the topic of communicative access, which is meant as the result of a visual translation of several tourist information. Therefore, it focuses on the design process of digital communication formats aimed at providing “experiential” representations of the territory and its identity. To explain the process, a research project carried out by the authors will be presented as a case study

Revisiting Signature of Minimal Gauge Mediation

We revisit phenomenology of the minimal gauge-mediated model. This model is motivated from the SUSY CP and flavor problems. A specific feature of this model is that \tan\beta is naturally large, since the B term in the Higgs potential is zero at the messenger scale. This leads to significant SUSY contributions to various low-energy observables. We evaluate the anomalous magnetic moment of the muon and the branching ratio of \bar{B}\to X_s\gamma taking account of recent theoretical and experimental developments. We find that the current experimental data prefer a low messenger scale (\sim 100 TeV) and gluino mass around 1 TeV. We also calculate the branching ratios of \bar{B}\to X_s l^+l^-, B_s\to \mu^+\mu^-, and B^-\to \tau^- \bar{\nu}, and show that these observables are strongly correlated with each other in this model.Comment: 20 pages, 16 figure

The Hypotensive and bradycardic effects of mouth opening: evidence in an animal model.

Objective Previous studies in normotensive anesthetized rats (Lapi Arch.Ital.Biol 151:11-23,2013) showed that peripheral stimulation of the trigeminal nerve induced by submaximal mouth opening (mandibular extension, ME) caused prolonged (at least 80min) bradycardia, hypotension and cerebral hemodynamic changes (pial arterioles showed a characteristic response pattern consisting in a significant constriction during ME followed by a dilatation for the entire remaining observation time). Design and method In this study we assessed the in vivo effects of ME on HR, MABP and pial microcirculation in hypertensive rats. Experiments were performed in male Wistar rats weighing 250-300g (n = 8). Hypertension was induced by intraperitoneal daily injection of dexamethasone (0.03mg/kg/day) for 10 days. ME was obtained by inserting an ad hoc developed retractor between the dental arches. HR and MABP were recorded by ECG and a catheter placed in the left femoral artery and measured by a computer-assisted system. Pial arterioles were observed through a closed cranial window implanted above the left parietal cortex and visualized by an in vivo fluorescence microscopy technique to assess vessel diameter changes before (baseline), during 10min ME and thereafter until 160min. Arteriolar diameters were measured with a computer-assisted method (MIP Image program, frame by frame). Results In sham-treated (no ME) hypertensive rats (n=3) HR, MABP and pial microcirculation did not change during whole observation period. Hypertensive rats subjected to ME (n=5) showed a significant decrease of HR and MABP. HR declined by 42bpm, (p<0.01) starting from 60 min after ME up to 160min, while MABP by 18mmHg (p<0.05) starting from 20min after ME up to 100min, compared with baseline. Pial arterioles exhibited a biphasic response: the arteriolar diameter decreased by 2.94&#956;m (p<0.05) during ME, afterwards it significantly increased by 3.46&#956;m (p<0.01) starting from 20min after ME; this vasodilatation lasted for the whole observation period. Conclusions Our results suggest that ME is able to exert profound and prolonged regulatory effects on systemic arterial blood pressure and pial arteriolar tone in hypertensive rats

In vitro evaluation of antiviral and virucidal activity of a high molecular weight hyaluronic acid.

BACKGROUND: hyaluronic acid (HA), a non-sulphated glycosaminoglycan, is present in synovial fluid, vitreous humour serum and many connective tissues. Pharmaceutical preparations of HA are used in clinical practice for wound healing, joint pain, kerato-conjunctivitis, asthma, mouth care, oesophageal-reflux, and gastritis. Moreover, it is used as a filler to counteract ageing and facial lipoatrophy. Our study aims at investigating the in vitro antiviral activity of a high molecular weight HA.METHODS: the MTT test was used to rule out the potential toxic effects of HA on the different cell lines used in the antiviral assays. The antiviral activity of HA against Coxsackievirus B5, Herpes simplex virus-1, Mumps virus, Adenovirus-5, Influenza Virus A/H1N1, Human Herpesvirus-6, Porcine Parvovirus, Porcine Reproductive and Respiratory Syndrome Virus was assessed by virus yield assays.RESULTS: the most effective inhibition was observed against Coxsackievirus B5, with 3Log reduction of the virus yield at 4mg/ml, and a reduction of 3.5Log and 2Log, at 2mg/ml and 1mg/ml, respectively: the selectivity index was 16. Mumps virus was highly inhibited too showing a reduction of 1.7Log at 1mg/ml and 1Log at 4mg/ml and 2mg/ml (selectivity index = 12). The selectivity index for Influenza Virus was 12 with the highest inhibition (1Log) observed at 4mg/ml. Herpes simplex virus-1 and Porcine Parvovirus were mildly inhibited, whereas no antiviral activity was observed with respect to Adenovirus-5, Human Herpesvirus-6, Porcine Reproductive and Respiratory Syndrome Virus. No HA virucidal activity was ever observed against any of the viruses tested. Kinetic experiments showed that both Coxsackievirus B5 and Herpes simplex virus-1 replication were consistently inhibited, not influenced by the time of HA addition, during the virus replication cycle.CONCLUSIONS: the spectrum of the antiviral activity exhibited by HA against both RNA and DNA viruses, known to have different structures (with or without envelope) and replication strategies, suggests a non specific mechanism of action, probably involving cell membrane-virus interaction steps. The results of the kinetic experiments support this hypothesis

Lepton Polarization Asymmetry in B l l(bar) decays in R-parity violating Minimal Supersymmetric Standard Model

We study the implication of R-parity violating Rp Minimal Supersymmetric Standard Model (MSSM) model in lepton polarization asymmetry ALP in B l l(bar) decays . The analysis show that the ALP is significant in a certain phenomenological parametric region of Yukawa couplings. We have also placed indirect bounds on Lambda' lambda couplings as obtained from B t t(bar).Comment: 6 pages, 4 figures Changes of notation in Eq(8-11,17-19),Eq.20 adde
