Quasi-elastic barrier distribution as a tool for investigating unstable nuclei

open access: yes, 2004
The method of fusion barrier distribution has been widely used to interpret the effect of nuclear structure on heavy-ion fusion reactions around the Coulomb barrier.

Performance of T-shape barriers with top surface covered with absorptive quadratic residue diffusers [PDF]

open access: yes, 2008
A previous paper [Applied Acoustics 66 (2005) 709–730] has shown that adding a quadratic residue diffuser (QRD) to the top of a T-shape barrier can provide better barrier performance than an equivalent purely absorptive barrier.

Robust Pitch Autopilot Design Based on Logarithmic Barrier Lyapunov Method [PDF]

open access: yesHangkong bingqi
When the phased array radar-guided missile intercepts a high speed target with large maneuvering, the aerodynamic parameters of the missile body vary dramatically and become nonlinear, which affects the response of the control system to the large angle ...

Cooperative Optimization With Globally Coupled Cost Function and Coupled Constraints

open access: yesIEEE Access
In this paper, we study the cooperative optimization problem of multi-agent systems with globally coupled cost function and coupled constraints, and design a distributed computing framework combining potential game theory underlying geometric projection.

Modeling and Characteristic Analysis of Wireless Ultrasonic Vibration Energy Transmission Channels through Planar and Curved Metal Barriers

open access: yesShock and Vibration, 2018
Wireless ultrasonic vibration energy transmission systems through metal barriers based on piezoelectric transducers have drawn a lot of focus due to the advantage of nonpenetration of the barriers, thus maintaining the integrity of sealed structures.

Non-invasive Methods for in vivo Determination of the Skin Barrier Function – Advantages of Confocal Raman Microspectroscopy [PDF]

open access: yesИзвестия Саратовского университета. Новая серия: Физика, 2020
The physical barrier of the stratum corneum (SC) is provided by corneocytes and the lateral organization of intercellular lipids, which necessarily includes the orthorhombic organization phase.

A Crank-Nicolson finite difference approach on the numerical estimation of rebate barrier option prices

open access: yesCogent Economics & Finance, 2019
In modelling financial derivatives, the pricing of barrier options are complicated as a result of their path-dependency and discontinuous payoffs. In the case of rebate knock-out barrier options, discount factors known as rebates are introduced, which ...

Dexamethasone for Chemotherapy‐Induced Nausea and Vomiting Prevention in Pediatric Patients: International Consensus

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background An international Delphi panel of experts developed consensus statements to delineate the circumstances where the risks of dexamethasone as an antiemetic do and do not outweigh its benefits. Procedure Experts in supportive care of pediatric patients were invited to participate.

Klein tunneling through an oblique barrier in graphene ribbons

open access: yes, 2010
We study a transmission coefficient of graphene nanoribbons with a top gate which acts as an oblique barrier. Using a Green function method based on the Dirac-like equation, scattering among transverse modes due to the oblique barrier is taken into ...
