We study the effect of fluid flow on three-dimensional (3D) dendrite growth using a phase-field model on an adaptive finite-element grid. In order to simulate 3D fluid flow, we use an averaging method for the flow problem coupled to the phase-field method and the semi-implicit approximated projection method (SIAPM). We describe a parallel implementation for the algorithm, using the CHARM++ FEM ...

Comparison of atom probe tomography (APT) results from different instruments, different users, or different samples requires confidence in overall reconstruction accuracy. The conventional reconstruction algorithm utilizes a single point-projection onto a spherical surface [1,2]. Although there are a limited number of parameters used to prescribe how detector events are converted to a 3D set of...

The septal extension graft is a very useful method of controlling nasal lengthening and tip projection, rotation, and shape by fixing a graft to the septum, which leads to a strong supporting structure. Enhancing graft stability is important for better long-term outcomes and minimizing complications or relapse, and even more efficient application of these methods is needed for East Asians who l...

OBJECTIVE To describe in detail a technique to achieve cephalic rotation, projection, and narrowing of the nasal tip, the "new domes" technique. DESIGN Retrospective analysis of more than 3000 primary rhinoplasties performed during the last 20 years. SETTING A private facial plastic surgery practice in Bogotá, Colombia. INTERVENTION Through an endonasal cartilage delivery approach to the ...

Mating yeast cells remove their cell walls and fuse their plasma membranes in a spatially restricted cell contact region. Cell wall removal is dependent on Fus2p, an amphiphysin-associated Rho-GEF homolog. As mating cells polarize, Fus2p-GFP localizes to the tip of the mating projection, where cell fusion will occur, and to cytoplasmic puncta, which show rapid movement toward the tip. Movement ...

Several surgeons advise a variety of tip sutures and describe their own techniques in open approach. Septocolumellar suture is one of them and can be described as a loop suture between the medial crura and caudal septum. Although some of the articles mention that it can be applied in closed rhinoplasty, there is no description of the technical details. This paper presents indications, technical...

The Saccharomyces cerevisiae protein Sph1p is both structurally and functionally related to the polarity protein, Spa2p. Sph1p and Spa2p are predicted to share three 100-amino acid domains each exceeding 30% sequence identity, and the amino-terminal domain of each protein contains a direct repeat common to Homo sapiens and Caenorhabditis elegans protein sequences. sph1- and spa2-deleted cells p...

The new species Ceropegia longirostris Thulin, M.G.Gilbert & Kaariye is described, illustrated and mapped. It known from two localities, one on gypsum in the Somali National Regional State (Ogaden) southeastern Ethiopia one, based a photographic record, just east of Lake Turkana northwestern Kenya. member C. sect. Phalaena H.Huber, distinctive by having flowers with corolla glabrous outside api...

A member of the cellulose synthase-like (subfamily D) gene family of Arabidopsis, AtCSLD3, has been identified by T-DNA tagging. The analysis of the corresponding mutant, csld3-1, showed that the AtCSLD3 gene plays a role in root hair growth in plants. Root hairs grow in phases: First a bulge is formed and then the root hair elongates by polarized growth, the so-called "tip growth." In the muta...

Several interacting systems exhibit at the tip of their long tidal tails massive condensations of atomic hydrogen, which may be the progenitors of Tidal Dwarf Galaxies. Because, quite often, these tails are observed edge-on, projection effects have been claimed to account for the large HI column densities measured there. Here we show that determining the velocity field all along the tidal featu...
