Wearable Augmented Reality: Research Trends and Future Directions from Three Major Venues.

Wearable Augmented Reality (AR) has attracted considerable attention in recent years, as evidenced by the growing number of research publications and industry investments. With swift advancements and a multitude of interdisciplinary research areas within wearable AR, a comprehensive review is crucial for integrating the current state of the field. In this paper, we present a review of 389 research papers on wearable AR, published between 2018 and 2022 in three major venues: ISMAR, TVCG, and CHI.

Learning Theories Applied to Teaching and Improving Hydrogeological Conceptualization.

Conceptual change is the process of developing a new understanding of an idea or related set of ideas and has been researched and theorized extensively in the last few decades. Although there is ongoing debate about how and why conceptual change occurs, all agree that individuals' prior knowledge plays a role, everyone engages differently in the process, and the context of the learning environment is influential. In this paper we build upon the work explored by Jimenez-Martinez (this issue) on conceptual change in hydrogeology, and explore how the conceptual change theory of Vosniadou may facilitate understanding the learning process in hydrogeology.

The next wave of innovation in laboratory automation: systems for auto-verification, quality control and specimen quality assurance.

Laboratory automation in clinical laboratories has made enormous differences in patient outcomes, with a wide range of tests now available that are accurate and have a rapid turnaround. Total laboratory automation (TLA) has mechanised tube handling, sample preparation and storage in general chemistry, immunoassay, haematology, and microbiology and removed most of the tedious tasks involved in those processes. However, there are still many tasks that must be performed by humans who monitor the automation lines.

An inexpensive robotic gantry to screen and control soil moisture for plant experiments.

Controlling water content in soil is a recurrent and labor intensive operation on almost any experiment about plant physiology. Here we describe a robotic gantry to measure and control soil moisture in pots that is modular, inexpensive, easy to build, accurate, precise, and reliable. Machines can be stacked into industrial shelves, coupled with other control systems to conduct multifactorial experiments, and adjusted to accommodate numerous pots of any size allowing for experiments with limitless specimen capacity in terms of height and specimen count.

Natural language processing of radiology reports for the identification of patients with fracture.

Unlabelled: Text-search software can be used to identify people at risk of re-fracture. The software studied identified a threefold higher number of people with fractures compared with conventional case finding. Automated software could assist fracture liaison services to identify more people at risk than traditional case finding.

Factors affecting the ability of baclofen to reduce fat intake in rats.

The GABA-B agonist baclofen has been reported to reduce the consumption of vegetable shortening, but not lard, in rats. This study sought to examine some of the factors that could account for these differences. Baclofen (0, 1.

Relationship between regular walking, physical activity, and health-related quality of life.

Background: The current physical activity (PA) and health-related quality of life (HRQoL) literature warrants further investigation with general population samples. The exploratory-focused purpose of this study was to compare total PA-HRQoL and walking-HRQoL relations, include a measure of general happiness, and to evaluate potential activity-HRQoL demographic moderators.

Methods: A random sample of 351 adults completed an adapted Godin Leisure Time Questionnaire, the SF-36, and the Satisfaction with Life Scale.

Integrating the perceived neighborhood environment and the theory of planned behavior when predicting walking in a Canadian adult sample.

Purpose: To integrate the characteristics of the perceived environment with the theory of planned behavior (TPB) to determine (1) whether the TPB mediates relations among environmental characteristics and walking, and (2) whether the environment moderates TPB-walking relations.

Design: Cross-sectional.

Setting: South Vancouver Island, British Columbia, Canada.

Relationships among dog ownership and leisure-time walking in Western Canadian adults.

Background: Dog ownership may be an effective tailored intervention among adults for promoting physical activity. This study examined the relationship between walking, physical activity levels, and potential psychological mediators between people who owned dogs and those who did not own dogs in the Capital Region District of Greater Victoria, British Columbia, Canada. Data were collected in September 2004; analyses were conducted in January 2005.

The 80-hour work week: will we have less-experienced graduating surgeons?

Objective: Our primary concern when modifying the Mount Carmel Medical Center surgical residency to comply with the "80-hour work week" was the effect on operative experience. Our goal was to measure the impact that work-hour restrictions have on operative volumes and to evaluate the potential benefit of a night rotation to minimize the number of "lost operations."

Design: Categorical surgical residents (PGY I-IV) recorded missed surgical procedures on post-call days from September 1, 2002 to March 31, 2004.

Role of NADH shuttles in glucose-induced insulin secretion from fetal beta-cells.

The NADH shuttle system, which transports the substrate for oxidative metabolism directly from the cytosol to the mitochondrial electron transport chain, has been shown to be essential for glucose-induced activation of mitochondrial metabolism and insulin secretion in adult beta-cells. We examined the role of these shuttles in the fetal beta-cell, which is immature in being unable to secrete insulin in response to glucose. The activity and concentration of the two key enzymes of the NADH shuttles, mitochondrial glycerol phosphate dehydrogenase (mGPDH) and mitochondrial malate dehydrogenase (mMDH), were eight- and threefold lower, respectively, in fetal compared with adult rat islets.
