36. Influence of nonlinearity to box-counting dimensions of spiral orbits for two-dimensional differential systems.

Abstract

This study focuses on spiral orbits approaching the origin of two-dimensional nonautonomous nonlinear systems. The main result explains that the fractal dimensions (box-counting dimensions) of spiral orbits of the systems on the phase plane can be derived from the power of the nonlinear term. The examples given show that when the coefficients are power functions, the balance between their power and the power of the nonlinear term determines the fractal dimension. In addition, some numerical simulations are also included. [ABSTRACT FROM AUTHOR]

37. Domain coarsening in viscous sintering as a result of topological pore evolution.

Abstract

• Domain coarsening is defined as the increase of mean intercept length with densification in sintering. • Decrease of surface area is the origin, as mean intercept length is inversely proportional to specific surface area. • Domain coarsening is common to viscous sintering of glass particles and solid state sintering of crystalline particles. • Topological change of pore channel is related to domain coarsening, which must be distinguished from grain growth. The microstructure evolution in 3D was studied by X-ray microtomography to reveal the relation between topology of pore networks and characteristic length in viscous sintering. The mean intercept length was defined from solid/pore interface for characterizing the length of solid phase and pore phase. The increase of the characteristic length with densification was termed as domain coarsening. The topological pore evolution was analyzed by using genus. The characteristic length increased with decreasing genus in the intermediate stage. The domain coarsening takes place as a natural consequence of pore evolution in viscous sintering, i.e., the decrease of total surface area concurrent with the topological transformations.

Abstract

• Hydroxyzine, a histamine H 1 receptor antagonist, augmented α and δ bicoherence in both sevoflurane anesthesia and propofol anesthesia. • Hydroxyzine augmented θ bicoherence in sevoflurane anesthesia but not in propofol anesthesia. • Hydroxyzine enhances both sevoflurane anesthesia and propofol anesthesia at surgical anesthetic depth probably by facilitation of GABAergic neural circuit mechanisms. The aim of this study was to determine the anesthesia-promoting effects of hydroxyzine on electroencephalograms during sevoflurane anesthesia and during propofol anesthesia. We analyzed 40 patients scheduled for elective surgery under sevoflurane anesthesia (n = 20) or propofol anesthesia (n = 20). Anesthesia was adjusted at a bispectral index value of 50–60, and then 0.5 mg/kg of hydroxyzine was administered intravenously. We analyzed frontal electroencephalograms before and after hydroxyzine injection with power spectral and bicoherence analyses, which are suitable for assessing the anesthetic depth induced by γ-aminobutyric acid (GABA)ergic anesthetics. Hydroxyzine increased the α bicoherence peaks in both sevoflurane anesthesia (mean difference, 11.2%; 95% confidence interval (CI), 7.6 to 14.8; P < 0.001) and propofol anesthesia (mean difference, 5.6%; 95% CI, 1.7 to 9.4; P = 0.008). Hydroxyzine increased the averaged δ bicoherence values in both sevoflurane anesthesia (mean difference, 5.5%; 95% CI, 2.1 to 8.8; P = 0.003) and propofol anesthesia (mean difference, 3.9%; 95% CI, 1.0 to 6.8; P = 0.011). Hydroxyzine enhances both sevoflurane anesthesia and propofol anesthesia probably by facilitation of GABAergic neural circuit mechanisms. The findings provide a new insight into the role of histaminergic neurons during general anesthesia in humans. [ABSTRACT FROM AUTHOR]

Abstract

• Navigated drill reduces the lateral/rostral deviation of cervical pedicle screw. • The drill set in low speed can graze the cortex of cervical pedicle safely. • The drill is useful to reduce the injuries of vertebral artery and nerve roots. Retrospective cohort study. This study was performed to evaluate the accuracy of cervical pedicle screw (CPS) placement with use of a navigated surgical drill (ND) and to compare it with navigated manual probe (MP) at C3–C6. 47 consecutive patients (27 males and 20 females, 67.2 [33–91] years) underwent a posterior cervical fixation using CPSs under an intraoperative 3D - – CT based navigation system (total 207 CPSs). For initial probing, ND with 2.2-mm steel burr was used since Apr. 2017 (Group ND; 33 patients, 152 CPSs). MP was used earlier (Group MP; 14 patients, 55 CPSs). There were no other different procedures between the two groups. The accuracy of CPS placement was graded with postoperative CT and compared between the two groups. There were no significant differences in the total perforation rates both in axial and sagittal planes between Groups ND and MP (axial; 7.2% vs. 14.5%, p = 0.25, sagittal; 10.5% vs. 14.5%, p = 0.46). However, the lateral and rostral perforation rates were significantly reduced in Group ND compared to Group MP (lateral: 36.4% vs. 87.5%, p = 0.04; rostral: 6.3% vs. 100%, p = 0.001). Although ND did not decrease the total perforation rate significantly, it reduced the incidence of lateral and rostral perforation. ND is likely to make initial probing easier without a forcible manipulation which might cause vertebral rotation. [ABSTRACT FROM AUTHOR]

50. Preparation and gas permeance of c-axis oriented zeolite membrane using ion-exchanged mordenite zeolite crystals oriented in magnetic field.

Abstract

• c -axis oriented mordenite zeolite membranes were produced under a magnetic field. • Na (b -axis) was exchanged with transition metals and rare earth ions (a - and c -axis). • c -axis oriented membranes exhibited improved N 2 permeation. C -axis-oriented mordenite (MOR) zeolite membranes were fabricated and evaluated for nitrogen permeance. MOR crystals having Na+ as a counter-ion exhibit b -axis-orientation parallel to a magnetic field, but c -axis-orientation was achieved by exchanging the counter-ion with transition metal or rare earth ions. The oriented seed layers were prepared by dropping each MOR seed slurry on a porous substrate placed in a 10 T magnetic field. The MOR crystals with Mn2+, Co2+, Ni2+, Pr3+, Nd3+, and Gd3+ ions produced c -axis-oriented seed layers parallel to the magnetic field, while the Fe2+, Cu2+, Eu3+, Er3+, and Yb3+ counter-ion MOR crystals exhibited c -axis alignment perpendicular to the field. MOR crystals with Co2+ and Cu2+ counter-ions revealed orientation even in 1 T. The porous substrate with the oriented seed layer was immersed in a zeolite synthesis solution to produce a c -axis-oriented zeolite membrane via a hydrothermal treatment. C -axis-oriented membranes exhibited improved N 2 permeation, demonstrating their effectiveness. [ABSTRACT FROM AUTHOR]
