The elastic pressure/volume (P/V) curve obtained by the multiple linear regression (MLR) technique using a new model, was compared with the quasi-static P/V points obtained by the rapid airway occlusion technique. Seven infants were studied during mechanical ventilation using a pressure controlled mode. The resistive pressure was subtracted from airway opening pressure, thus determining the ela...

The chromium/vanadium bimetallic Phillips catalysts developed by our research group have been proved to be a promising process to produce bimodal polyethylene using a single-reactor process. The vanadium loading of CrV-1/1, CrV-1/2, and CrV-1/3 has a significant effect on the polymerization activity, product molecular weight (MW), as well as th...

We construct a family of integrable equations the form vt = f(v; vx; vxx; vxxx) such that f is transcendental function in v; vxx. This related to Krichever-Novikov equation by differential substitution. Our construction and corresponding substitutions involves geometry genus two curves their Jacobians.

Memristors have pinched hysteresis loops in the V − I plane. Ideal memristors are everywhere non-linear, cross at zero and are rotationally symmetric. In this paper we extend memristor theory to produce different types of non-ideality and find that: including a background current (such as an ionic current) moves the crossing point away from zero; including a degradation resistance (that increas...

OBJECTIVES The shape of the flow-volume (F-V) curve is known to change to showing a prominent plateau as stenosis progresses in patients with tracheal stenosis. However, no study has evaluated changes in the F-V curve according to the degree of bronchial stenosis in patients with unilateral main bronchial stenosis. METHODS We performed an analysis of F-V curves in 29 patients with unilateral ...

Jingzhaotoxin-V (JZTX-V), a 29-residue polypeptide, is derived from the venom of the spider Chilobrachys jingzhao. Its cDNA determined by rapid amplification of 3' and 5'-cDNA ends encoded an 83-residue precursor with a pro-region of 16 residues. JZTX-V inhibits tetrodotoxin-resistant and tetrodotoxin-sensitive sodium currents in rat dorsal root ganglion neurons with IC50 values of 27.6 and 30....

The numerical approximation scheme for solving the nonlinear initial value problem ∂tb(v) = ∂xxβ(x, v) + β(x, v) with periodic boundary conditions is presented. Local existence and uniqueness of a solution and convergence of approximations is a consequence of the results of Mikula and Kačur (1996), where the anisotropic curvature driven evolution of plane convex curves is studied. The considere...

We show that the decidability of an amplification of Hilbert’s Tenth Problem in three variables implies the existence of uncomputably large integral points on certain algebraic curves. We obtain this as a corollary of a new positive complexity result: the Diophantine prefixes ∃∀∃ and ∃∃∀∃ are generically decidable. This means, taking the former prefix as an example, that we give a precise geome...

The split-C(V) technique has served during three decades for independent extraction of the inversion and accumulation charge in MOSFETs from the direct measurement of the gate-to-channel capacitance [1]. The total charge, Q, obtained from the integration of the gateto-channel capacitance curves, can be used for the evaluation of the carrier mobility using the standard MOSFET equations (μ α ID/Q...
