Leptoquark patterns unifying neutrino masses, flavor anomalies, and the diphoton excess

Vector leptoquarks provide an elegant solution to a series of anomalies and at the same time generate naturally light neutrino masses through their mixing with the standard model Higgs boson. We present a simple Froggatt-Nielsen model to accommodate the B physics anomalies $R_K$ and $R_D$, neutrino masses, and the $750$ GeV diphoton excess in one cohesive framework adding only two vector leptoquarks and two singlet scalar fields to the standard model field content.Comment: 12 pages, 10 figures; final version published in PR

Personality Characteristics Which Predispose Potentially Self-Destructive Behaviors

In the college setting, many adolescents choose to engage in potentially self-destructive behaviors such as smoking, drinking, and body piercing, despite the associated risks. It is hypothesized that the tendency to participate in these behaviors is correlated with personality characteristics. Personality tests measuring sensation seeking, locus of control, and impulsiveness, along with three scales measuring the tendency to participate in three self-destructive behaviors: smoking, drinking, and body decoration, were administered to 102 college-aged students. Results showed that most of the self-destructive behaviors were negatively correlated with subscales of the sensation seeking measure. One possible explanation of these results would be the conservative, Catholic, campus culture of the university. However, more research is necessary to substantiate this type of group difference

Electrochemical synthesis and characterization of self-supported polypyrrole-DBS-MWCNT electrodes

The electrochemical conditions (electrolyte potential window, monomeric oxidation) for the synthesis of polypyrrole- dodecylbenzenesulfonate-multiwalled carbon nanotube (PPy-DBS-MWCNT) composite were determined. Thick PPy-DBS-MWNT films were electrogenerated and peeled off from the working electrode. Selfsupported PPy-DBS-MWCNT electrodes were fabricated. The morphology of the film was analyzed by SEM. Self-supported electrodes were characterized by potential cycling and by consecutive square potential waves in NaClO4 aqueous solution with different cathodic potential limits. Higher reduced structures (the current never drops to zero) are obtained and analyzed fromvoltammetric responses until rising cathodic potential limits (up to−5 V). For high cathodic potentials (N−1 V) a slow hydrogen evolution coexists with the film reduction, as revealed from coulovoltammetric (charge-potential) responses, and the reduction rate decreaseswithout significant polymeric degradation. Degradation of the material electroactivity in NaClO4 is initiated by anodic overpotentials beyond 1.2 V. Both, oxidation and reduction chronoamperometric responses prove the presence of nucleation processes, most significant during oxidation. Chronocoulometric responses illustrate slower oxidation rates from deeper reduced initial states. The electrochemical responses are explained by reaction-driven conformational and structural changes that are clarified by the coulovoltammetric response

Dispersion of tracer particles in a compressible flow

The turbulent diffusion of Lagrangian tracer particles has been studied in a flow on the surface of a large tank of water and in computer simulations. The effect of flow compressibility is captured in images of particle fields. The velocity field of floating particles has a divergence, whose probability density function shows exponential tails. Also studied is the motion of pairs and triplets of particles. The mean square separation is fitted to the scaling form ~ t^alpha, and in contrast with the Richardson-Kolmogorov prediction, an extended range with a reduced scaling exponent of alpha=1.65 pm 0.1 is found. Clustering is also manifest in strongly deformed triangles spanned within triplets of tracers.Comment: 6 pages, 4 figure

Stellenwert der pelvinen Lymphadenektomie beim klinisch lokalisierten Prostatakarzinom

Zusammenfassung: Der Stellenwert und die Ausdehnung der pelvinen Lymphadenektomie beim klinisch lokalisierten Prostatakarzinom werden weiterhin kontrovers diskutiert. Die Lymphadenektomie stellt jedoch bis heute die einzige Methode für ein exaktes Tumorstaging dar. Es gibt zunehmend Hinweise, dass das Entfernen von allen befallenen Lymphknoten einen positiven Einfluss auf das tumorfreie Überleben und evtl. auf das Gesamtüberleben haben könnte. Aus diesem Grund sollte, wenn eine Lymphadenektomie durchgeführt wird, diese Entlang der V.iliaca externa, in der Fossa obturatoria und beidseits Entlang der A.iliaca interna erfolge
