Piezoelectric Pb((Zn 1/3 Nb 2/3 ) 0.91 Ti 0.09 )O 3 (PZNT 91/9) single crystals 40 mm in diameter were successfully grown from solution by the Bridgman method with a PbO flux. The platinum crucible heated to 1130°C. Growth rate was 0.35 mm/h. obtained ~40 20 length and rust‐brown color. Curie temperature, T C , ranged 175° 185°C, dielectric constant before poling at room temperature 2000‐8900 within wafer. After electrical poling, specimens had electromechanical coupling coefficients...
Abstract Mortality and recurrence rates of hepatocellular carcinoma (HCC) remain high despite the use various treatment methods. Recently, cell-based immunotherapy using natural killer (NK) cells has attracted considerable attention in cancer immunotherapy. NK generated from induced pluripotent stem (iPSCs) are a new option for as an cell resource. The eNK (HLCN061, developed by HEALIOS K.K.) human iPSC-derived differentiated clinical-grade iPSCs which IL-15, CCR2B, CCL19, CD16a, NKG2D have...
Liver abscesses typically respond well to a combination of antibiotics and drainage. However, some cases can be resistant treatment pose clinical challenge. Infections caused by mucoid-type Klebsiella pneumoniae are rare, but highly invasive, lead conditions such as liver hematogenous dissemination, resulting in systemic complications. Herein, we present the case an 80-year-old woman with recurrent multilocular abscess K. who was successfully treated hepatic artery antibiotic infusion...
A 96-channel phased array probe for echocardiography using a single-plate, 0.91Pb(Zn 1/3 Nb 2/3 )O 3 –0.09PbTiO (PZNT 91/9) single-crystal transducer with dimensions of 14×20 mm has been fabricated to realize greater sensitivity and broader bandwidth properties. The center frequency the probe, 3.5 MHz, was selected cover bandwidths two conventional lead zirconate titanate (PZT) ceramic probes frequencies 2.5 3.75 MHz. solder paste used connect flexible printed circuit PZNT 91/9 transducer....
We show that Rubinstein-Scharlemann graphics for 3-manifolds can be regarded as the images of singular sets (: discriminant set) stable maps from into plane.As applications our understanding graphic, we give a method describing Heegaard surfaces in by using arcs plane, and an orbifold version Rubinstein-Scharlemann's setting.Then this setting, every genus one 1-bridge position nontrivial two bridge knot is obtained 2-bridge standard manner.
In this paper, we show that, for any integers $n\geq 2$ and $g\geq 2$, there exist genus-$g$ Heegaard splittings of compact 3-manifolds with distance exactly $n$.
We show that the degenerations of tunnel numbers knots under connected sum can be arbitrarily large.
We describe probably the simplest 3-manifold which contains closed separating incompressible surfaces of arbitrarily large genus. Two applications this observation are given. (1) For any closed, orientable .
Dielectric and piezoelectric properties of 0.93Pb(Zn1/3Nb2/3)O3–0.07PbTiO3 (PZNT 93/7) single crystals (PSC) have been investigated. The PZNT 93/7 (SC) with diameters 40 mm were grown successfully by the Bridgman method PbO flux. dielectric constant SC at room temperature was about 3500, which is slightly larger than that 91/9 SC. Phase-transition temperature, Trt, 108°C, 40°C higher SC; however, Curie Tc, 170°C, 10°C lower coupling factor rectangular bar mode, k33', 84% as large k33' value...
We show that for any link L, there exists a Seifert surface L is obtained by successively plumbing flat annuli to disk D, where the gluing regions are all in D. This furnishes new way of coding links. also present an algorithm read code directly from braid presentation.
Temperature dependence of the dielectric and piezoelectric properties xPb(Zn1/3Nb2/3)O3–yPbTiO3 (PZNT 100x/100y) single crystals (PSC) was investigated to estimate heat stability their properties. The coupling factor rectangular bar mode k33'=81% PZNT 91/9 decreased sharply at about 70°C then gradually toward Curie temperature, Tc. On other hand, k33'=62% 95.5/4.5 hardly changed up 110°C, although it lower than that room temperature. degradation temperatures k33' value were roughly in...
In this paper, we show that any unknotting tunnel for a two bridge knot is isotopic to either one of known ones. This together with Morimoto–Sakuma’s result gives the complete classification tunnels knots up isotopies and homeomorphisms. AMS Classification 57M25; 57M05

In this paper, we develop the idea of Thompson which treats relationship between bridge position, incompressible meridianal planar surfaces, and thin position.We show that for a link in position there exits canonical depth 1 nested tangle decomposition with 2-spheres arising from (Proposition 3.7), is maximal essential closely related to (Theorem 4.3).
In this paper, we introduce a distance [Formula: see text] on the equivalence classes of spherical curves under deformations type RI and ambient isotopies.

Given a knot K in closed orientable manifold M we define the growth rate of tunnel number to be . As our main result prove that Heegaard genus is strictly less than exterior if and only 1. In particular this shows non-trivial S3 never asymptotically super additive. The gives conditions imply falsehood Morimoto's Conjecture.
