Pasteuria penetrans is a bacterial parasite of some plant parasite of nematodes whichcan attach to the cuticle of nematode. Differences in attachment of P. penetrans spores to the second stag juvenile (J2) cuticle may provide evidence for nematode cuticle diversity even between different ages of J2s. For investigating this purpose, we studied the effect of different ages of th...

We investigate critical properties of the stacked-J1-J2 Ising model on a cubic lattice. Using Monte Carlo simulations and renormalization group, we find single phase transition first order for J2/J1>1/2. The renormgroup approach predicts that can be second from universality class O(2) model, but results show another set exponents: exponents continuously vary form values typical first-order in f...

We establish the conditional asymptotic stability in a local energy norm of unstable soliton for one-dimensional quadratic Klein-Gordon equation under even perturbations. A key feature problem is positive gap eigenvalue exhibited by linearized operator around soliton. Our proof based on several virial-type estimates, combining techniques from series works [23], [24], [25], [27], [28], and an ex...

We present a migration velocity analysis (MVA) method based on wavefield extrapolation. Similarly to conventional MVA, our method aims at iteratively improving the quality of the migrated image, as measured by the flatness of angle-domain commonimage gathers (ADCIGs) over the aperture-angle axis. However, instead of inverting the depth errors measured in ADCIGs using ray-based tomography, we in...

Assessing the stability of higher-dimensional rotating black holes requires a study of linearized gravitational perturbations around such backgrounds. We study perturbations of Myers-Perry black holes with equal angular momenta in an odd number of dimensions (greater than five), allowing for a cosmological constant. We find a class of perturbations for which the equations of motion reduce to a ...

Although perturbations from a stable equilibrium must ultimately vanish, they can grow initially, and the maximum initial growth rate is called reactivity. Reactivity thus identifies systems that may undergo transient population surges or drops in response to perturbations; however, we lack biological and mathematical intuition about what makes a system reactive. This paper presents upper and l...

resemble streamwise vortices and streaks. A somewhat We study the Linearized Navier-Stokes (LNS) equations from an input-output point of view by analyzing their spatio-temporal frequency responses. We show how the relative roles of Tollmien-Schlichting (TS) waves and streamwise vortices and streaks can be explained as input-output resonances of the spatiotemporal frequency responses.
