Immature blow flies (Calliphoridae) are typically the first colonizers of cadavers. Identification of the early instars using traditional, morphology-based keys is difficult because of their small size, similarity, and simplicity in external morphology. Information derived from molecular genetic data would augment the accurate identification of immature flies. Nine species of blow flies commonl...

In the first part of the paper, we give an explicit algorithm to compute the (genus zero) Gromov-Witten invariants of blow-ups of an arbitrary convex projective variety in some points if one knows the Gromov-Witten invariants of the original variety. In the second part, we specialize to blow-ups of Pr and show that many invariants of these blow-ups can be interpreted as numbers of rational curv...

Our primary long-term goal is to assess whether respiratory sample ("blow") analysis can be developed as a practical method of physiological stress assessment in free-living cetaceans. Few methods exist for assessment of physiological stress levels of free-swimming cetaceans (Amaral 2010, ONR 2010). Respiratory samples (blow) can potentially be collected from targeted individuals and from large...

Lagrangian spheres in the symplectic Del Pezzo surfaces arising as blow-ups of CP in 4 or fewer points are classified up to Lagrangian isotopy. Unlike the case of the 5-point blow-up, there is no Lagrangian knotting.

Non-invasive sampling techniques are increasingly being used to monitor glucocorticoids, such as cortisol, as indicators of stressor load and fitness in zoo and wildlife conservation, research and medicine. For cetaceans, exhaled breath condensate (blow) provides a unique sampling matrix for such purposes. The purpose of this work was to develop an appropriate collection methodology and validat...

For certain singularly perturbed two-component reaction-diffusion (RD) systems, the bifurcation diagram of steady-state spike solutions is characterized by a saddle-node behavior in terms of some parameter β in the system. For some such systems, such as the Gray-Scott model, a spike self-replication behavior is observed as a parameter varies across the saddle-node point. We demonstrate and anal...

We consider the two dimensional L critical nonlinear Schrödinger equation i∂tu+ ∆u+ u|u| = 0. In the pioneering work [2], Bourgain and Wang have constructed smooth solutions which blow up in finite time T < +∞ with the pseudo conformal speed ‖∇u(t)‖L2 ∼ 1 T − t , and which display some decoupling between the regular and the singular part of the solution at blow up time. We prove that this dynam...

We study finite-time blow-up for pseudo-relativistic Hartreeand Hartree-Fock equations, which are model equations for the dynamical evolution of white dwarfs. In particular, we prove that radially symmetric initial configurations with negative energy lead to finite-time blow-up of solutions. Furthermore, we derive a mass concentration estimate for radial blow-up solutions. Both results are math...

For the carrion-feeding blow flies, a common source of vitellogenic protein are the carcasses that also serve as larval substrates. This attraction continues well after the blow flies have ceased to oviposit on the carrion, and it has been assumed that a decomposed cadaver remains a suitable source for vitellogenic protein; however, this assumption has never been tested. To test this hypothesis...

In 1961 Rossmann & Blow published a simple procedure for analytically combining the phase probabilities derived from various isomorphous derivatives or other phase-determining procedures [Rossmann & Blow (1961). Acta Cryst. 14, 641--647]. However, they found it necessary to make an approximation in obtaining the expression for the lack of closure (8) of the phase triangle. In 1970 Hendrickson &...
