High-resolution 3D imaging and modeling is an important application in the heritage field. We describe several demonstration projects conducted collaboration with museums conservation agencies.

High blood pressure (BP) is the most common cause of death and disability in world, largest contributor to heart kidney disease. Current methods measuring monitoring require either invasive procedures or intermittent inflation a cuff restrict flow. Thus non-invasive method for continuous needed. Pulse transit time (PTT), has been reported be highly correlated with but data examining effect posture activity on PTT based BP estimation are very limited. In this paper, was computed using...

Cardiovascular diseases are the leading cause of death globally, causing nearly 17.9 million deaths per year. Therefore, early detection and treatment critical to help improve this situation. Many manufacturers have developed products monitor patients' heart conditions as they perform their daily activities. However, very few can diagnose complex anomalies beyond detecting rhythm fluctuation. This paper proposes a new method that combines Short-Time Fourier Transform (STFT) spectrogram ECG...

The Vif protein of human immunodeficiency virus type 1 is required for productive replication in peripheral blood lymphocytes. Previous reports suggest that vif-deleted viruses are limited because a defect the late steps life cycle. One remaining questions to determine whether functional role involves specific interaction with core proteins. In this study, we demonstrate direct between and Pr55Gag precursor vitro as well infected cells. No observed mature capsid protein. Pr55Gag-Vif detected...

Delineation of the cardiac right ventricle is essential in generating clinical measurements such as ejection fraction and stroke volume. Given manual segmentation on first frame, one approach to segment from all magnetic resonance images find point correspondence between sequence images. Finding with non-rigid transformation requires a deformable image registration algorithm, which often involves computationally expensive optimization. The central processing unit (CPU)-based implementation...

Abstract Background/Introduction Though echocardiography remains the most utilized imaging modality in daily cardiology practice, a major challenge physical strain and injury that can be induced echocardiographer. Purpose We developed prototype robotic arm assisted system which incorporates robotics with traditional echocardiography. assessed safety feasibility of 31 volunteers. Methods An ultrasound transducer was mounted upon (UR10 arm, Universal Robots, Odense, Denmark). The connected to...

Past research has linked theta oscillations (electroencephalographic activity in the 4-8-Hz range) to spatial navigation rodents and humans, encoding retrieval of information rodents. In present study, electroencephalographic was measured while humans navigated through virtual mazes. Results confirmed previous findings that frequency episodes is directly related difficulty maze navigation. We were also able show occur most likely at points a where new hallways come into view, or after...

Millions of people in Canada have impairments that result a loss function and directly affect their ability to carry out activities daily living. Many individuals with disabilities enter into rehabilitation programs improve motor functioning quality life. Currently, many the exercises are performed monotonous, uninteresting, do not inspire patients perform best abilities. The usage traditional can also make it difficult for therapists objectively measure track patient progress. integration...

We present an experience-based approach to designing a collaborative interactive performance, humanaquarium. Our research explores public interaction with digital technology through the practice-based inquiry of inter-disciplinary team designers and musicians. method experience from within, literally situating ourselves within performance/use space assuming roles both performers as we develop refine humanaquarium project over course year's worth performances.

Background Surgical design and simulation (SDS) is a useful tool to help surgeons visualize the anatomy of patient perform operative maneuvers on computer before implementation in operating room. While these technologies have many advantages, further evidence their potential improve outcomes required. The present benchtop study was intended identify if there difference surgical outcome between free-hand surgery completed without virtual planning (VSP) software preoperatively planned with use...

Abstract In this perspective, we offer insights into the evolution of CGIAR’s research and innovation portfolio from 2019 to 2023, underpinning transformative journey towards One CGIAR. With contribution, aim strengthen social environmental sustainability components allied, future Research for Development (R4D) portfolios. We explore three interlinked operational frameworks—Quality (QoR4D), Comparative Advantage (CA) Analysis, Inclusive Innovation—and present practical tools lessons...

A method of estimating range flow (space displacement vector field) on nonrigid as well rigid objects from a sequence images is described. This can directly estimate the deformable motion parameters by solving system linear equations that are obtained substituting transformation expressed Jacobian matrix into constraints based an extension conventional scheme used in intensity image sequences. The computed these estimated transformation. algorithm supported experimental estimations sheet...

The effect of haptic interfaces on motor skill training has been widely studied. However, relatively little is known about whether can promote long-term acquisition. In this paper, we report two experimental studies that investigated the effectiveness visuohaptic (visual + haptic) in helping people develop short-term and skills. Our first study compared outcomes training, visual no-assistance training. We found for tested methods were similar when participants second experiment assessed...

Home blood pressure ( BP ) telemonitoring and pharmacist case management reduce , but cost‐effectiveness assessments are mixed. We examined the incremental of this intervention vs usual care in Canadians with cerebrovascular disease. A Markov decision model cost‐utility analysis examining community‐residing, high‐risk patients a recent nondisabling event was created. lifetime time horizon health payer perspective were used. Achieved future cardiovascular risks, attendant consequences on...

Understanding of the exact cause patellofemoral pain has been limited by methodological challenges to evaluate in-vivo joint motion. This study compared six degree-of-freedom patellar motion during a dynamic lunge task between individuals with and healthy individuals. Knee joints eight females ten were imaged using CT scanner in supine lying position, then dual-orthogonal fluoroscope while they performed lunge. To quantify motion, three-dimensional models knee bones, reconstructed from...

Creating models of real objects is a complex task for which the use traditional modeling techniques has proven to be difficult. To solve some these problems, laser rangefinders are frequently used sample an object's surface from several viewpoints resulting in set range images that registered and integrated into final triangulated model. In practice, due reflectance properties, occlusions accessibility limitations, certain areas usually not sampled, leaving holes create undesirable artifacts...
