The shock-induced collapse of a pre-existing nucleus near a solid surface in the focal region of a lithotripter is investigated. The entire flow field of the collapse of a single gas bubble subjected to a lithotripter pulse is simulated using a high-order accurate shock- and interface-capturing scheme, and the wall pressure is considered as an indication of potential damage. Results from the co...

Implant-based breast reconstruction after mastectomy offers excellent cosmetic results in select individuals. However, this technique may result in a step-off between the implant and the soft tissue of the chest wall, which can be problematic in the extremely thin patient. Also, the removal of soft tissue can result in prominent ribs and visible intercostal spaces. A number of surgical options ...

Increased arterial wall tension stimulates growth and remodeling of arteries, but little is known about the effects of decreased wall tension, despite its developmental and pathological significance. Consequently, we cuffed 1 carotid artery in rabbits with a portion of the contralateral artery to off-load circumferential wall tension. The model produced rapid and extensive atrophy of the cuffed...

Early in infection, pathogens encounter the outer wall of plant cells. Because pathogen hydrolases targeting the plant cell wall are well-known components of virulence, it has been assumed that wall disassembly by the plant itself also contributes to susceptibility, and now this has been established experimentally. Understanding how plant morphological and developmental remodeling and pathogen ...

We investigate the dynamics of a one-dimensional asymmetric exclusion process with Langmuir kinetics and a fluctuating wall. At the left-hand boundary, particles are injected onto the lattice; from there, the particles hop to the right. Along the lattice, particles can adsorb or desorb, and the right-hand boundary is defined by a wall particle. The confining wall particle has intrinsic forward ...

We study how fluxes on the domain wall world volume modify quantum fusion of two distant parallel domain walls into a composite wall. The elementary wall fluxes can be separated into parallel and antiparallel components. The parallel component affects neither the binding energy nor the process of quantum merger. The antiparallel fluxes, instead, increase the binding energy and, against naive ex...

Within the domain wall-mediated electroweak baryogenesis, we study fermion scattering off a CP -violating wall in the background of an uniform magnetic field. In particular, we calculate the asymmetry between the reflection coefficients for right-handed and left-handed chiral fermions, ∆R = RR→L − RL→R , which is of relevance in non local baryogenesis mechanisms. PACS number(s): 12.15.Ji, 11.30...

I discuss the applicability of classical techniques to the study of the dynamics of infrared, bosonic fields at the electroweak phase transition. I present the lattice as a natural means of cutting off hard, nonclassical modes, and discuss the problem of integrating out the excluded modes perturbatively. I then apply the classical lattice technique to study the dynamics of the phase interface (...

Effect of arterial wall compliance on the invasive coronary diagnostic parameters for various severities of coronary stenoses was assessed. The Mooney-Rivlin model was used to define the non-linear properties of the arterial wall and the plaque regions. The nonNewtonian viscosity of blood was modeled using the Carreau model. A finite element method was employed to solve the pulsatile fluid (blo...
