A model for equilibrium surface in form a truncated cone, made basis spherical model. Methods determining technological protrusion; calculation depth implementation protrusion counter body; assessment pattern change module, load meshing. evaluating ratio actual and nominal...

We report the effects of grain boundary (GB) protrusion on off-state current (IOFF) p-channel polycrystalline silicon thin-film transistors by using three-dimensional technology computer-aided design (TCAD) simulation. found that IOFF at a high drain bias, VDS = −10 V, varies more than 10 times as position GB changes, whereas it less two if has no protrusion, i.e. flat surface. The TCAD analysi...

The role of feedback in the self-regulation star formation is a fundamental question astrophysics. Orion Nebula nearest site ongoing and recent massive formation. It unique laboratory for study stellar feedback. Recent SOFIA [CII] 158 $\mu$m observations revealed an expanding bubble, Veil shell, being powered by winds ionization We have identified protrusion-like substructure Northwest portion ...

PURPOSE We evaluated the accuracy of detrusor wall thickness and intravesical prostatic protrusion, and the association of each test to diagnose bladder prostatic obstruction in patients with lower urinary tract symptoms. MATERIALS AND METHODS We enrolled in the study 100 consecutive patients with lower urinary tract symptoms due to benign prostatic hyperplasia. Baseline parameters were Inter...

Changes in the acanthopteran (acanthopterygian) system of premaxillary protrusion are traced from its incipient representation in the iniomous (myctophiform) genus Aulupits to its fully evolved form in the percoids. Two complementary components of the system are differentiated. One is the protrusion of the premaxillary, brought about primarily by the anteroventral movement of a ligament attache...

Calpain 2 regulates membrane protrusion during cell migration. However, relevant substrates that mediate the effects of calpain on protrusion have not been identified. One potential candidate substrate is the actin binding protein cortactin. Cortactin is a Src substrate that drives actin polymerization by activating the Arp2/3 complex and also stabilizes the cortical actin network. We now provi...

The correction of a severe maxillary protrusion in an adult by distal movement of the maxillary molars has been one of the most difficult biomechanical problems in orthodontics. This article reports on the treatment of an adult case of severe maxillary protrusion and a large overjet treated with a skeletal anchorage system. A female patient, age 22 years and 3 months, complained of the difficul...

Dynamic membrane protrusions such as lamellipodia and filopodia are driven by actin polymerization and often hijacked by intracellular microbes to enter host cells. The overall rate of membrane protrusion depends on the actin polymerization rate and the increase of localized cell volume. Although the signaling pathways involving actin polymerization are well characterized, the molecular mechani...
