Distal femoral morphology as a risk factor for osteoarthritis

open access: yesThe Anatomical Record, EarlyView.
Abstract Osteoarthritis (OA) is a leading cause of disability affecting millions of adults in the United States, commonly resulting in the need for total knee arthroplasty (TKA) to restore mobility and quality of life. This study investigates potential differences in baseline distal femoral shape between individuals who received TKA due to OA and a ...

Are Noncovalent C─H⋯ Au Bonds Comparable to C─H⋯ π Bonds? A Theoretical Perspective

open access: yesChemistry – An Asian Journal, EarlyView.
In this study, the geometry and stability features as well as the physical nature of C─H···Au and C─H···π noncovalent complexes have been analyzed and compared at the PBE0‐D3/def2‐TZVP level of theory involving a series of alkanes and i) graphene and ii) an Au layer. Abstract Herein, we have theoretically studied and compared the physical nature of C─H·

Linear Matrix Inequality‐based design of distributed proportional‐integral‐derivative for the output consensus tracking in heterogeneous high‐order multi‐agent systems

open access: yesAsian Journal of Control, EarlyView.
Abstract This article addresses the cooperative output consensus tracking problem for high‐order heterogeneous multi‐agent systems via a distributed proportional‐integral‐derivative (PID)‐like control strategy and proposes two novel control methodologies for the tuning of the control gains, which do not require any assumption and/or limitation on agent

A dual‐driven event‐triggered mechanism for observer‐based sliding mode control of stochastic uncertain Markov jump systems

open access: yesAsian Journal of Control, EarlyView.
Abstract This paper investigates the problem of observer‐based sliding mode control (SMC) of stochastic uncertain Markov jump systems using dual‐driven event‐triggered mechanism (ETM). The ETM is implemented not only in the system output to the observer channel but also in the feedback channel, forming a dual ETM, which can effectively reduce ...
