Awake Rejuvenation With the Deep Plane Face Lift and Extended Deep Neck Contouring. [PDF]

open access: yesPlast Reconstr Surg Glob Open
Background:. The deep plane face lift corrects progressive soft tissue sagging and neck laxity associated with the aging process. With patients requesting fewer procedures under general anesthetics, trends have turned toward performing minimally invasive

Metallic structures on tangent bundles of Lorentzian para-Sasakian manifolds [PDF]

open access: yesJournal of Mahani Mathematical Research, 2023
Let M be a Lorentzian para-Sasakian manifold with a Lorentzian para-Sasakian structure (φ,η,ξ,g). In this paper, we introduce some metallic structures on tangent bundle of the manifold M using vertical, horizontal and complete lifts of the Lorentzian ...

A COMPLETE LIFT FOR SEMISPRAYS [PDF]

open access: yesInternational Journal of Geometric Methods in Modern Physics, 2010
In this paper, we define a complete lift for semisprays. If S is a semispray on a manifold M, its complete lift is a new semispray Scon TM. The motivation for this lift is two-fold: First, geodesics for Sccorrespond to the Jacobi fields for S, and second, this complete lift generalizes and unifies previously known complete lifts for Riemannian metrics,

Lift Force of Airfoil (NACA 0012, NACA 4612, NACA 6612) With Variation of Angle of Attack and Camber: Computational Fluid Dynamics Study

open access: yesComputational and Experimental Research in Materials and Renewable Energy, 2021
Airfoil is a cross section from air plane wings can affect aerodynamic performance to lift force (FL). The lift force generated by airfoil has different values due to several external and internal factors, including angle of attack, flow rate and camber.

Lifting geometric objects to the dual of the first jet bundle of a bundle fibred over R [PDF]

open access: yes, 2013
We study natural lifting operations from a bundle E over R to the dual bundle of its first-jet bundle. The main purpose is to define a complete lift of a type (1,1) tensor field on E and to understand all features of its construction.

Time-domain Analytical Method for Aeroelastic Analysis of High Aspect Ratio Wing Using Unsteady Indicial Aerodynamics [PDF]

open access: yesINCAS Bulletin, 2022
This paper deals with the development of a novel time-domain analytical method to perform an aeroelastic stability analysis of a high aspect ratio wing. The aerodynamic model in this paper is built upon the frequency domain of Theodorsen aerodynamics. An

A Short Note on a Mus-Cheeger-Gromoll Type Metric

open access: yesJournal of New Theory, 2023
In this paper, we first show that the complete lift $U^{c}$ to $TM$ of a vector field $U$ on $M$ is an infinitesimal fiber-preserving conformal transformation if and only if $U$ is an infinitesimal homothetic transformation of $(M,g)$.

Research on transition corridor boundary of distributed propulsion VTOL fixed wing

open access: yesXibei Gongye Daxue Xuebao, 2022
The transition state is the most critical and dangerous state of the VTOL fixed wing aircraft in the whole flight process. In this paper, a transition corridor for a distributed propulsion VTOL fixed-wing aircraft is studied based on the lift ...
