Structural Characterization of IBV Glycoproteins

1984
Avian infectious bronchitis virus (IBV) causes economically important disease in chickens, affecting both respiratory and non-respiratory tissues. Like other coronaviruses IBV virions contain three virus-coded protein structures, the spike (S; surface projection, peplomer), nucleocapsid (N) and matrix (M) proteins1. The polypeptides of M and N proteins

Dynamic IBVS control of an underactuated UAV

2012 IEEE International Conference on Robotics and Biomimetics (ROBIO), 2012
In this paper image based visual servo approach for 3D translational motion and yaw rotation of an under-actuated flying robot is considered. Taking into account the complexity of dynamics of flying robots, main objective of this paper is to consider the dynamics of these robots in designing an image based control strategy.

Analysis of Messenger RNA within Virions of IBV

1994
The presence of subgenomic mRNAs (sgRNAs) in virions of infectious bronchitis virus was examined by probing Northern blots of RNA extracted from virions using as a probe a cDNA of the 3'-terminal nucleocapsid protein (N) gene. The sgRNAs were readily detected even after extensive purification of virions and after RNase A treatment of virions. The molar

Optimal motion control for IBVS of robot

Proceedings of the 10th World Congress on Intelligent Control and Automation, 2012
In conventional image-based visual servoing (IBVS), the robot end-effector (camera) motion is controlled directly according to image error, there isn't direct control over the Cartesian velocities of the robot end-effector. As a result, the robot trajectories can be seemingly roundabout in Cartesian space. This paper presents a new control scheme, that

IBVS with fuzzy sliding mode for robot manipulators

2015 International Workshop on Recent Advances in Sliding Modes (RASM), 2015
Closed loop control of robot manipulator's end effector pose with visual feedback is called as visual servoing (VS). As one of the approaches for VS, image-based visual servoing (IBVS) has the advantage of no pose estimation for commonly used eye-in-hand configured manipulators.

Sequences Required for Replication and Packaging of IBV RNA

2001
We have used a naturally occurring IBV defective RNA (D-RNA), CD-91 (9.1 kb; Penzes et al., 1994) to investigate IBV replication and packaging signals. This D-RNA comprised the 5’-most 1133 nucleotides (domain I, including the 528 nucleotide 5’ untranslated region, UTR) and 3’-most 1626 nucleotides (domain III) of the genome and a middle section ...

Treatment of Heterogeneous Emphysema Using the Spiration IBV Valves

Thoracic Surgery Clinics, 2009
Ninety-eight emphysema patients were treated at 13 international sites during a 3-year series of single-arm, open-label studies with the IBV valve and a multi-lobar treatment approach. Fifty six percent of subjects had a clinically meaningful improvement in health-related quality of life, but standard pulmonary function and exercise studies were ...

In ovo interference of embryo non-lethal avian infectious bronchitis viruses (IBV) with velogenic Newcastle disease virus and embyro adapted IBV

Research in Veterinary Science, 1986
Avian infectious bronchitis virus (IBV) interfered with the lethal effects of velogenic Newcastle disease virus (NDV) and embryo adapted IBV in eggs previously inoculated with non-lethal IBV. Greater interference was noted in eggs superinfected with embryo adapted IBV than velogenic NDV.

IBVS and the data from robotic observatories

Astronomische Nachrichten, 2004
AbstractAutomatic telescopes and surveys dump stellar variability data at ever increasing rates.We discuss what the Information Bulletin on Variable Stars (Comm. 27 & 42 of the IAU) can do with this data and to what extent Virtual Observatory techniques could be applied.We introduce IBVS DataService, the figure database and the photometric sequence
