OBJECTIVE To calculate the values of the phase angle of septic patients using bioelectrical impedance analysis, correlate the values with clinical and biochemical variables, and compare them to reference values. METHODS Cohort study conducted with 50 septic patients aged ≥ 18 years old, admitted to intensive care units, and assessed according to prognostic indexes (APACHE II and SOFA), clinic...

Brewster angle microscopy N·dodecyl·y·hydroxybutyric acid amide synchrotron X·ray grazing incidence diffraction 4'·oclyl-1,1 '-biphenyl-4·carbonilride Brewster angle microscopy has been involved in some of tho recent advances in tho field of monomolecular layers, such as the detection of a phase transition in monolayars formed by a surfactant at the solution surface, the determination of the li...

Introduction: An accurate phase function is necessary for precise photometric correction of the Clementine lunar UVVIS images. Although several researchers have proposed photometric models for Clementine UVVIS images using empirical phase functions (e.g., [1] [2] [3]), additional work is required for correction of the data at small phase angle (<20), because the phase function at small phase an...

The purpose of this study was to identify the kinematic and kinetic strategies used by patients with unilateral triple arthrodesis or subtalar fusion during level walking, stair ascent, stair descent and to determine the influence of these different conditions on kinematics and kinetics. Nine subjects with unilateral triple or subtalar fusion and five normal control subjects were recruited for ...

In this paper we study the dynamical contact angle at three phase (fluid-fluid-solid) contact points for the 2 dimensional steady-state moving liquid drop. We present a result giving the speeds at the contact points as a function of the dynamical contact angle, in the form of a simple algebraic expression. The only physical constants involved are the viscosities of the fluids and the surface te...

In a nematic gel, the appearance of nematic order is accompanied by a spontaneous elongation of the gel parallel to the nematic director. If such a gel is made chiral, it has a tendency to form a cholesteric helical texture, in which local elongation of the gel parallel to the nematic director is suppressed due to the requirement of elastic compatibility. We show that a conical helix in which t...

In a general two-Higgs-doublet model (2HDM), without the ad hoc discrete symmetries to prevent tree-level flavor-changing-neutral currents, an extra phase angle in the charged-Higgs-fermion coupling is allowed. We show that the charged-Higgs amplitude interferes destructively or constructively with the standard model amplitude depending crucially on this phase angle. The popular model I and II ...

In this paper the Phase-Matching bandwidth, effective nonlinear coefficient and the walk-off angle within the effective bandwidth of the LiGa(SexS1-x)2 biaxial nonlinear crystals are calculated using the Genetic algorithm (GA). This calculation is held for all tree principle XY, YZ and XZ planes individually. The results are shown the accuracy of the applied algorithm is quite qualified.

A new noncooperative iris recognition method is proposed. In this method, the iris features are extracted using a Gabor descriptor. The feature extraction and comparison are scale, deformation, rotation, and contrast-invariant. It works with off-angle and lowresolution iris images. The Gabor wavelet is incorporated with scale-invariant feature transformation (SIFT) for feature extraction to bet...

The refraction of linearly polarized plane waves into a half–space occupied by a material moving at constant velocity was studied by directly implementing the Lorentz transformations of electric and magnetic fields. From the perspective of a co–moving observer, the moving material was a spatially local, pseudochiral omega material. Numerical studies revealed that whether or not negative refract...
