Reconstruction of maxillofacial bone defects: Contemporary methods and future techniques [PDF]

open access: yes, 2014
Reconstruction of maxillofacial continuity defects has always been a challenging tasks for the scientist and surgeons over the years. The main goal of the reconstruction of the maxillofacial region is to restore facial form, function, full ...

Oxygen‐Doped 2D In2Se3 Nanosheets with Extended In‐Plane Lattice Strain for Highly Efficient Piezoelectric Energy Harvesting

open access: yesAdvanced Science
With the emergence of electromechanical devices, considerable efforts have been devoted to improving the piezoelectricity of 2D materials. Herein, an anion‐doping approach is proposed as an effective way to enhance the piezoelectricity of α‐In2Se3 ...

The Effects of Daily Consumption of Functionalized Yogurts with Sacha Inchi Oil and Interspecific Hybrid Palm Oil on the Lipid Profile and ApoB/ApoA1 Ratio of Healthy Adult Subjects

open access: yesFoods
Sacha Inchi oil (SIO) and hybrid palm oil (HPO) are potential sources of unsaturated fatty acids to improve the lipid profile of dairy products. This study evaluated, for the first time, the effects of the daily consumption of yogurts with enhanced fatty

Induced Scattering and Two-Photon Absorption of Alfven Waves with Arbitrary Propagation Angles

open access: yes, 2000
The equation for temporary evolution of spectral energy of collisionless Alfven waves is derived in framework of weak turbulence theory. The main nonlinear processes for such conditions are induced scattering and two quantum absorption of Alfven waves by

Gauge invariance and weak forces in an isotropic medium [PDF]

open access: yesarXiv, 2002
We demonstrate that the neutrino kinetic equation derived by the standard Bogolyubov method is formally gauge non-invariant and give a recipe how to recast it to the gauge invariant form recovering the standard Lorentz form weak force term which apparently conserves the lepton current.

Design of a bioreactor to study the role of red blood cells in the transport of nitric oxide in the microcirculation [PDF]

open access: yes, 2007
Nitric oxide (NO) plays an important role in physiological functions like vasodilation, neurotransmission, and inhibition of platelet aggregation. The endothelium-derived NO diffuses into the vascular lumen where it interacts with flowing blood as well ...

Quasi-neutral limit of the Euler-Poisson and Euler-Monge-Ampère systems [PDF]

open access: yesarXiv, 2005
This paper studies the pressureless Euler-Poisson system and its fully non-linear counterpart, the Euler-Monge-Amp\`ere system, where the fully non-linear Monge-Amp\`ere equation substitutes for the linear Poisson equation. While the first is a model of plasma physics, the second is derived as a geometric approximation to the Euler incompressible ...

Diffraction of waves by screens (apertures in screens) with time-varying dimensions. Time-varying Kirchhoff's integral representation for moving boundaries [PDF]

open access: yesarXiv, 2015
The diffraction of electromagnetic waves by screens (apertures in screens) with time-varying dimensions is studied. The generalized vector Kirchhoff's representation for this case is obtained. It is also shown that with accuracy up to the terms of the order of v/c<<1, the expressions for the scattered wave and instantaneous power can be derived from ...

Effect of oxygen plasma on nanomechanical silicon nitride resonators

open access: yes, 2017
Precise control of tensile stress and intrinsic damping is crucial for the optimal design of nanomechanical systems for sensor applications and quantum optomechanics in particular.
