A combined model reference adaptive control law for multirotor UAVs

IET Control Theory & Applications, 2021
Model reference adaptive control (MRAC) offers the potential to adapt in real‐time to changes in the performance of small unmanned air vehicles. There are significant challenges with their use, however, primarily in the implementation and assurance of ...

Funnel function‐based asymptotic output feedback control of hydraulic systems with prescribed performance

IET Control Theory & Applications, 2021
An asymptotic output feedback controller for the hydraulic systems with model uncertainty compensation and prescribed performance is proposed here, where state observers, funnel function and nonlinear adaptive controller are integrated via backstepping ...

Intravitreal GD2‐Specific Chimeric Antigen Receptor T‐Cell Therapy for Refractory Retinoblastoma

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Effective treatments for advanced, treatment‐resistant retinoblastoma (RB) remain limited. GD2‐specific chimeric antigen receptor (CAR) T cells show potent antitumor activity with minimal toxicity but have not previously been evaluated in RB.

Multi‐variable finite‐time observer‐based adaptive‐gain sliding mode control for fixed‐wing UAV

IET Control Theory & Applications, 2021
This paper presents a multivariable finite‐time observer‐based adaptive‐gain sliding mode control scheme for a fixed‐wing unmanned aerial vehicle (UAV) subject to the unmeasurable angular rates and unknown matched/unmatched disturbance.

Effects of the Fluid Replacement Method During Online Hemodiafiltration on the Solute Removal Performance and Biocompatibility Using the Asymmetric Cellulose Triacetate Membrane

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Pre‐dilution online hemodiafiltration (Pre‐HDF) is predominantly used in Japan, whereas post‐dilution online HDF (Post‐HDF) is more common in Europe. An asymmetric cellulose triacetate (ATA) membrane may improve biocompatibility.

Temporal and spatial variability of terrestrial diatoms at the catchment scale: controls on communities

PeerJ, 2020
Diatoms are generally regarded as inhabitants of water bodies. However, numerous taxa are able to survive and reproduce in a variety of non-aquatic ecosystems. Although terrestrial diatoms are discussed extensively in the literature, most of those studies covered floristic aspects and few information exists on their ecology.

Reciprocal control of viral infection and phosphoinositide dynamics

FEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

Factors controlling soil spatial variability in a native range landscape

, 1984
Soils were characterized along three transects of the same catenary sequence within the semi-arid shortgrass (Bouteloua gracilis) steppe of north central Colorado. The objectives of the study were to: 1. Evaluate which factor or combination of factors (i.e. parent material, topography, biota) is/are the most important controls on soil development, soil

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

FEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative
