Soft SUSY breaking grand unification: Leptons vs quarks on the flavor playground
2007
We systematically analyze the correlations between the various leptonic and hadronic flavor violating processes arising in SUSY Grand Unified Theories. Using the GUT-symmetric relations between the soft SUSY breaking parameters, we assess the impact of hadronic and leptonic flavor observables on the SUSY sources of flavor violation.
Diphoton resonance from a warped extra dimension
2016
We argue that extensions of the Standard Model (SM) with a warped extra dimension, which successfully address the hierarchy and flavor problems of elementary particle physics, can provide an elegant explanation of the 750 GeV diphoton excess recently reported by ATLAS and CMS. A gauge-singlet bulk scalar with ${\cal O}(1)$ couplings to fermions is identified as the new resonance $S$, and the vector-like Kaluza-Klein excitations of the SM quarks and leptons mediate its loop-induced couplings to photons and gluons. The electroweak gauge symmetry almost unambiguously dictates the bulk matter content and hence the hierarchies of the $S\to \gamma\gamma$, $WW$, $ZZ$, $Z\gamma$, $t\bar t$ and dije…
Les pôles de compétitivité structurent-ils les trajectoires professionnelles des jeunes diplômés ?
2012
National audience; La création des pôles de compétitivité en France a permis un investissement massif dans des projets de R&D dans certains territoires. S'appuyant sur le développement de synergie entre les entreprises, les centres de recherche et les établissements de formations, ces pôles devraient favoriser une politique de ressources humaines propices à l'innovation. Notre recherche propose d'examiner l'effet de la création de ces pôles sur le salaire des diplômés des écoles d'ingénieurs. Une méthode de différences de différences est utilisée pour comparer les rémunérations des jeunes diplômés avant et après la création des pôles. Les résultats montrent des effets positifs de la créatio…
The ras-related small GTP-binding protein RhoB is immediate-early inducible by DNA damaging treatments.
1995
The low molecular weight GTP-binding proteins RhoA, RhoB, and RhoC are characterized as specific substrates for the ADP-ribosyltransferase C3 from Clostridium botulinum and are supposed to be involved in the organization of the microfilamental network and transformation. rhoB is known to be immediate-early inducible by growth factors and protein-tyrosine kinases. Since increasing evidence indicates overlapping of growth factor- and UV-induced signal pathways, we studied the effect of UV light and other genotoxic agents on early rhoB transcription. Within 30 min after UV irradiation of NIH3T3 cells, the amount of rhoB mRNA increased 3-4-fold. Elevated rhoB mRNA was accompanied by an increase…
Hepatic farnesyl diphosphate synthase expression is suppressed by polyunsaturated fatty acids
2005
Dietary vegetable oils and fish oils rich in PUFA (polyunsaturated fatty acids) exert hypocholesterolaemic and hypotriglyceridaemic effects in rodents. The plasma cholesterol-lowering properties of PUFA are due partly to a diminution of cholesterol synthesis and of the activity of the rate-limiting enzyme HMG-CoA reductase (3-hydroxy-3-methylglutaryl-CoA reductase). To better understand the mechanisms involved, we examined how tuna fish oil and individual n−3 and n−6 PUFA affect the expression of hepatic FPP synthase (farnesyl diphosphate synthase), a SREBP (sterol regulatory element-binding protein) target enzyme that is subject to negative-feedback regulation by sterols, in co-ordination …
Measurement of theE2/M1Ratio in theN→ΔTransition Using the Reactionp(γ→,p)π0[Phys. Rev. Lett. 78, 606 (1997)]
1997
The small electric quadrupole $E2$ amplitude of the predominantly magnetic dipole $M1$ $p\ensuremath{\rightarrow}\ensuremath{\Delta}(1232)$ transition has been measured using 270 to 420 MeV tagged linearly polarized photons in the $p(\stackrel{\ensuremath{\rightarrow}}{\ensuremath{\gamma}},p){\ensuremath{\pi}}^{o}$ reaction at the Mainz Microtron MAMI. Differential cross sections and photon asymmetries were determined by measuring the recoil proton in the cylindrically symmetric $4\ensuremath{\pi}$ detector DAPHNE. From the proton angular distributions the ratio $E2/M1\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}\ensuremath{-}(2.5\ifmmode\pm\else\textpm\fi{}0.2\ifmmode\pm\else\textpm\…
Una llamativa pieza reacuñada de la ceca Carissa (Cortijo de Carija, Cádiz)
2014
Se documenta un curioso ejemplar pesado cuya noved ad, además de la pieza en sí, la representan los dos glóbulos observables detrás de la cabeza galeada y que encontramos en el anverso. Estos glóbulos, concebidos como marca de v alor, pudieron ser del cuño original del anverso o, en su caso, de una pieza anterior a una reacuñación; aunque, finalmente, cabría otra posibilidad y que descartamos en este artículo: un nuevo valor a añadir, como un “As” o una “Unidad”, para la entonces ceca gaditana de Carissa . We present a curious heavy specimen whose novelty resides, besides the piece itself, in the two noticeable pellets behind the galley pro w on obverse. These pellets, conceived as a mark o…
Donazioni e ricompense:la retorica bizantina al servizio del potere normanno.
2009
Il documento d'archivio simbolo e cifra del potere anche quando questo si declina nella sfera del diritto privato. Una pergamena greca del 1141 attesta la donazione di reliquie sacre in favore dell'Archimandritato di Messina: autori e destinatari, testimoni, formulario e lessico bizantini concorrono a una precisa sceneggiatura del dispositivo politico normanno nell'epoca in cui Ruggero II e il suo ministro Giorgio di Antiochia hanno fatto delle forme mutuate dall'impero bizantino un raffinato strumento di regno. The archive document is the symbol and figure of power even when this is declined in the sphere of private law. A Greek parchment of 1141 attests the donation of sacred relics in fa…
Diputación y Germanía: Nueva historia de una aportación financiera
2019
It's widely known, since long time ago, that the reign of Charles I began in the old kingdom of Valencia with the «Germanías»; a social conflict that finished by denerating into a civil war. In the following pages, we try to analyse the problems concerned with the finances of the army organized by the viceroy Diego Hurtado de Mendoza from the perspective of one of the institutions involved in the economic management of this army: the «Diputado del General».
Republicanos y Rebeldes más allá de las fronteras: Brasil y la Guerra Civil Española
2015
El objetivo de esta tesis es el de aclarar suficientemente un aspecto muy poco explorado por los investigadores: los reflejos de la Guerra Civil Española en Brasil. El origen de la tesis partió del presupuesto de que esos reflejos fueron mucho más intensos de lo que se cree, agrandados por el fuerte conflicto abierto entre los sectores de la derecha y de la izquierda brasileñas en los años 30. Por ello, sería contraproducente creer que esos grupos se mantuvieron absolutamente indiferentes ante un conflicto que era visto como la encarnación de las luchas entre socialismo y fascismo. Solamente una investigación mucho más profunda que cualquier otro trabajo hasta ahora publicado podría respond…
