Attitude Determination and Estimation using Vector Observations: Review, Challenges and Comparative Results [PDF]

arXiv, 2020
This paper concerns the problem of attitude determination and estimation. The early applications considered algebraic methods of attitude determination. Attitude determination algorithms were supplanted by the Gaussian attitude estimation filters (which continue to be widely used in commercial applications).

Chinese Expert Consensus on Standardized Outpatient Management of Sarcopenia in the Elderly (2024)

AGING MEDICINE, EarlyView.
In China, specific sarcopenia clinics are not sufficient for outpatients. This consensus combines the professional advice of domestic geriatrics experts, summarizes the existing domestic experience in the establishment of sarcopenia clinics, and provides guidance for the management of sarcopenia clinics.

Propagation of Uncertainty in Rigid Body Attitude Flows [PDF]

arXiv, 2007
Motivated by attitude control and attitude estimation problems for a rigid body, computational methods are proposed to propagate uncertainties in the angular velocity and the attitude. The nonlinear attitude flow is determined by Euler-Poincar\'e equations that describe the rotational dynamics of the rigid body acting under the influence of an attitude

Relationship Between Kyphosis and Postoperative Gastroesophageal Reflux After Proximal Gastrectomy

Annals of Gastroenterological Surgery, EarlyView.
This study examined the relationship between kyphosis and postoperative gastroesophageal reflux disease (GERD) after proximal gastrectomy using a kyphosis definition that is familiar to surgeons for preoperative assessment. Multivariate analysis revealed that kyphosis is an independent risk factor for GERD after proximal gastrectomy.

Global Attitude Estimation using Single Direction Measurements [PDF]

arXiv, 2006
A deterministic attitude estimator for a rigid body under an attitude dependent potential is studied. This estimator requires only a single direction measurement to a known reference point at each measurement instant. The measurement cannot completely determine the attitude, but an attitude estimation scheme based on this measurement is developed; a ...

Multiple Sampling Capsule Robot for Studying Gut Microbiome

Advanced Intelligent Systems, EarlyView.
A multiple sampling capsule robot (MSCR) is developed for longitudinal gut microbiome analysis. Employing electromagnetic field control, the MSCR can locomote actively, precisely align the selected channel, and collect up to six microbiome samples with minimal cross‐contamination.

Geometric Tracking Control of the Attitude Dynamics of a Rigid Body on SO(3) [PDF]

arXiv, 2010
This paper provides new results for a tracking control of the attitude dynamics of a rigid body. Both of the attitude dynamics and the proposed control system are globally expressed on the special orthogonal group, to avoid complexities and ambiguities associated with other attitude representations such as Euler angles or quaternions.

Promoting radical healing to facilitate community capacity building among formerly incarcerated Black and Latino men with substance use disorders

American Journal of Community Psychology, EarlyView.
Abstract This study reports on a qualitative thematic analysis of secondary data from group session recordings collected as part of the Community Wise Optimization Trial. Community Wise is a multilevel behavioral intervention designed to increase critical consciousness and reduce substance use among formerly incarcerated men living in predominantly ...

Vision-Based Relative Attitude Formation Tracking [PDF]

arXiv, 2012
Relative attitude formation control systems are developed for multiple spacecraft, based on the line-of-sight measurements between spacecraft in formation. The proposed control systems are unique in the sense that they do not require constructing the full attitudes of spacecraft and comparing them to obtain the relative attitudes indirectly.
