Oviposition behavior is a fairly neglected aspect in our understanding of the biology of sand flies. In this study, we used a comparative approach using both new- and old-world species (Lutzomyia longipalpis and Phlebotomus papatasi) in choice and no-choice oviposition chambers to evaluate the effect of old sand fly colony remains (frass), conspecific eggs, and their combination on oviposition ...

While one might assume that the force to break a chemical bond gives a measure of the bond strength, this intuition is misleading. If the force is loaded slowly, thermal fluctuations may break the bond before it is maximally stretched, and the breaking force will be less than the bond can sustain. Conversely, if the force is loaded rapidly it is more likely that the maximum breaking force is me...

Supersymmetric models with an inverted mass hierarchy (IMH: multiTeV first and second generation matter scalars, and sub-TeV third generation scalars) can ameliorate problems arising from flavor changing neutral currents, CP violating phases and electric dipole moments, while at the same time satisfying conditions on naturalness. It has recently been shown that such an IMH can be generated radi...

We consider the breaking of 5D SUSY G = SU(N +K) gauge symmetry into H = SU(N) × SU(K) × U(1) on an orbifold S/(Z2 × Z ′ 2). There appear two independent fixed points: one respects the full bulk gauge symmetry G while the other contains only the unbroken gauge symmetry H . In the model with one bulk (N + K)-plet, giving a K-plet as the zero mode, we show that localized non-abelian gauge anomali...

Abstract: We study the renormalizable abelian vector-field models in the presence of the Wess-Zumino interaction with the pseudoscalar matter. The renormalizability is achieved by supplementing the standard kinetic term of vector fields with higher derivatives. The appearance of fourth power of momentum in the vector-field propagator leads to the super-renormalizable theory in which the β-funct...
