Transition from psoriasis to psoriatic arthritis is characterized by distinct alterations in peripheral blood Tc17, Th17 and CD4+ TEM cells

Arthritis &Rheumatology, Accepted Article.
Objective Cellular mechanisms driving transition from psoriasis to psoriatic arthritis have remained largely elusive. Thus, we investigated changes within the peripheral blood T cell compartment associated with the transition phase. Methods In an observational study, 116 patients were examined and categorized into subgroups including psoriasis with at ...

Monocular visual servo control of a quadcopter for crossing windows, doors, and corridors

Asian Journal of Control, EarlyView.
Abstract This paper proposes a sequential visual servo control scheme for quadcopters, where the main goal is to drive a quadcopter to a desired pose while crossing windows, doors, or corridors using only visual feedback. This control scheme is composed of two stages that act in sequence: the approaching and pose regulation phases.

Full‐order observer design for quadratic port‐controlled Hamiltonian systems

Asian Journal of Control, EarlyView.
Abstract The full‐order observer design problem for a particular class of port‐controlled Hamiltonian systems is approached in this paper. The proposed full‐order observer scheme belongs to the structure preserving class of dynamic estimators as it preserves the natural stability properties of the approached class of systems that are useful for the ...

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

Asian 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 ...

Adaptive event‐based asynchronous approach for containment control of Markov jump multi‐agent systems with hidden Markov models

Asian Journal of Control, EarlyView.
Abstract This paper focuses on the issue of adaptive event‐triggered containment control for Markov jump multi‐agent systems characterized by hidden Markov jump parameters. The central objective is to design an output‐feedback controller for the Markov jump multi‐agent system by using an adaptive event‐triggered technique that not only ensures the ...
