The Feasibility of the Disturbance Accommodating Controller for Precision Antenna Pointing [PDF]

The objective of this study is to investigate the feasibility of a pointing (position loop) controller for the NASA-JPL Deep Space Network (DSN) antennas using the Disturbance Accommodating Control (DAC) theory.

Beyond PEGylation: Archaeal Lipids for Long‐Circulating Liposomes

Advanced NanoBiomed Research, EarlyView.
Archaeal lipid‐based liposomes, particularly those containing caldarchaeol (GDGT), were found to significantly prolong the circulation time of vancomycin in rats, matching the pharmacokinetic properties of PEGylated systems. These findings suggest archaeal lipids as promising non‐PEG excipients for parenteral applications to minimize drug clearance ...

Kontrolle heterogener Katalyse mittels Unter‐Oberflächen‐Sauerstoff

Angewandte Chemie, EarlyView.
Während der CO‐Oxidation auf Rhodiumoberflächen wird die Reaktionsdynamik in der Gegenwart von Unter‐Oberflächen‐Sauerstoff (Osub) deutlich verändert. Unter‐Oberflächen‐Sauerstoff stabilisiert vorübergehend durch Oberflächenreaktionen gebildetes physisorbiertes CO2, was diesem ermöglicht, vorübergehend zu binden und mit der Oberfläche zu thermalisieren.

Controlling Heterogeneous Catalysis With Subsurface Oxygen

Angewandte Chemie International Edition, EarlyView.
During CO oxidation on rhodium surfaces, the reaction dynamics are markedly altered in the presence of subsurface oxygen. Subsurface oxygen stabilizes the nascent physisorbed CO2 formed after the surface reaction, allowing it to become transiently trapped and thermalize with the surface.

Technobiological Pathways for High‐CO₂ Capture Using Micro‐/Macroalgae: Genetic Engineering, Process Automation, and Value‐Added Bioproducts

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Greenhouse gas (GHG) emissions have emerged as one of the most critical drivers of climate change; this is primarily due to high concentrations and long atmospheric life of carbon dioxide (CO2). For a significant amount of time, various biological processes such as microalgal cultivation, cyanobacterial systems, photosynthetic microorganisms ...

Detecting cryptic ghost lineage introgression in four‐taxon genomic datasets

Applications in Plant Sciences, EarlyView.
Abstract Premise Hybridization and introgression are pervasive evolutionary forces that have played fundamental roles in shaping the diversity of wild and domesticated plants. Four‐taxon tests for introgression provide a reliable framework for detecting signatures of ancient introgression from genomic data, which have played an important role in ...

Nasal soft‐tissue anatomy of Triceratops and other horned dinosaurs

The Anatomical Record, EarlyView.
Abstract Although ceratopsid dinosaurs possess a characteristically hypertrophied narial region, soft‐tissue anatomy associated with such a skeletal structure and their biological significance remain poorly understood. The present study provides the first comprehensive hypothesis on the soft‐tissue anatomy in the ceratopsid rostrum based on the Extant ...

Piecewise Linear Accrual Models: do they really control for the asymmetric recognition of gains and losses? [PDF]

The asymmetric recognition of gains and losses underlying conservative accounting is not taken into account by Jones (1991)-type accrual models. Recently, Moreira (2002) and Ball and Shivakumar (2005a) have proposed piecewise linear accrual models ...
