Effects of Aging on Patellofemoral Joint Stress during Stair Negotiation on Challenging Surfaces.

This study examined the effect of age and surface on patellofemoral joint (PFJ) stress magnitude and waveform during stair ascent and descent tasks. A total of 12 young and 12 older adults had knee biomechanics quantified while they ascended and descended stairs on normal, slick, and uneven surfaces. The peak of stance (0-100%) PFJ stress and associated components were submitted to a two-way repeated measures ANOVA, while the PFJ stress waveform was submitted to statistical parametric mapping two-way ANOVA.

Evaluation of an innovative dementia care competency model among physical and occupational therapy students.

The rising prevalence of dementia calls for a competent workforce capable of delivering quality dementia care. A standard for assessing dementia-care-specific competencies is necessary to guide curriculum development and implementation in a competency-based educational framework during academic training. This study evaluated the psychometric properties of the Dementia Care Competency Model (DCCM) among students enrolled in physical (PT) and occupational therapist (OT) programs.

Local adaptation to climate facilitates a global invasion.

Local adaptation may facilitate range expansion during invasions, but the mechanisms promoting destructive invasions remain unclear. Cheatgrass (), native to Eurasia and Africa, has invaded globally, with particularly severe impacts in western North America. We sequenced 307 genotypes and conducted controlled experiments.

Active remote sensing data and dispersal processes improve predictions for an invasive aquatic plant during a climatic extreme in Great Lakes coastal wetlands.

Invasive aquatic plants pose a significant threat to coastal wetlands. Predicting suitable habitat for invasive aquatic plants in uninvaded yet vulnerable wetlands remains a critical task to prevent further harm to these ecosystems. The integration of remote sensing and geospatial data into species distribution models (SDMs) can help predict where new invasions are likely to occur by generating spatial outputs of habitat suitability.

A Sensor Probe with Active and Passive Humidity Management for In Situ Soil CO Monitoring.

Soil CO concentration and flux measurements are important in diverse fields, including geoscience, climate science, soil ecology, and agriculture. However, practitioners in these fields face difficulties with existing soil CO gas probes, which have had problems with high costs and frequent failures when deployed. Confronted with a recent research project's need for long-term in-soil CO monitoring at a large number of sites in harsh environmental conditions, we developed our own CO logging system to reduce expense and avoid the expected failures of commercial instruments.

Shared fate was associated with sustained cooperation during the COVID-19 pandemic.

Did the COVID-19 pandemic bring people together or push them apart? While infectious diseases tend to push people apart, crises can also bring people together through positive interdependence. We studied this question by asking an international sample (N = 1,006) about their inclinations to cooperate, perceptions of interdependence (i.e.

Towards tunable exciton delocalization in DNA Holliday junction-templated indodicarbocyanine 5 (Cy5) dye derivative heterodimers.

We studied the exciton delocalization of indodicarbocyanine 5 dye derivative (Cy5-R) heterodimers templated by a DNA Holliday junction (HJ), which was quantified by the exciton hopping parameter . These dyes were modified at the 5 and 5' positions of indole rings with substituent (R) H, Cl, Bu, Peg, and hexyloxy (Hex) groups that exhibit different bulkiness and electron-withdrawing/donating capacities. The substituents tune the physical properties of the dyes, such as hydrophobicity (log ) and solvent-accessible surface area (SASA).

Hyperedge Representations with Hypergraph Wavelets: Applications to Spatial Transcriptomics.

In many data-driven applications, higher-order relationships among multiple objects are essential in capturing complex interactions. Hypergraphs, which generalize graphs by allowing edges to connect any number of nodes, provide a flexible and powerful framework for modeling such higher-order relationships. In this work, we introduce hypergraph diffusion wavelets and describe their favorable spectral and spatial properties.

All-Onlay Anterolateral Ligament Reconstruction Technique of the Knee.

The anterolateral ligament has gained attention as a secondary stabilizer of anterolateral rotatory stability of the knee. This has had implications among sports medicine specialists as an adjunct procedure with anterior cruciate ligament reconstruction to improve stability. As indications have evolved for its use as an anterior cruciate ligament reconstruction augment, so have the techniques for reconstruction.

Commercial infant products influence body position and muscle use.

The musculoskeletal and motor development of infants is affected by their environment, which varies from being held, lying on a firm flat surface, to seated in various nursery products. Nursery products can alter the body position of infants, particularly the position of the head/neck and trunk, which may inhibit an infant's ability to breathe. With U.

National Park visitors perceive benefits for themselves and wildlife under blended red-white outdoor lighting.

Visitors to Colter Bay Village in Grand Teton National Park were surveyed to elicit their evaluations of experimental outdoor lighting conditions. Luminaires capable of dimming and switching between two LED modules (white, blended red-white) were installed in street and parking areas. The blended red-white lamps consisted of 30 narrowband LED with a peak wavelength 623 nm and two 3000 K white LEDs.

A research agenda to advance the study of implementation mechanisms.

Background: Implementation science scholars have made significant progress identifying factors that enable or obstruct the implementation of evidence-based interventions, and testing strategies that may modify those factors. However, little research sheds light on how or why strategies work, in what contexts, and for whom. Studying implementation mechanisms-the processes responsible for change-is crucial for advancing the field of implementation science and enhancing its value in facilitating equitable policy and practice change.

What About Language?: A Mixed Methods Examination of the Impact of Person-Centered Language on Students' Perceptions of Individuals Who Commit Sex Offenses.

Person-centered language is a well-known approach to reducing stigmatizing labels among marginalized groups. However, little research has explored person-centered language's impact in criminal justice classrooms. Utilizing a mixed-method research design, this study explores the impact of person-centered language on students' perceptions of persons convicted of sex offenses.

The Impact of Load Mass and Distribution on Heart Rate, Perceived Exertion, and Accelerometer Measured Physical Activity During Running.

Many tactical athletes (military and emergency personnel) have fixed load carriage occupational requirements. Understanding the effects of running with common military "fighting loads" (no load to approximately 18 kg) on heart rate (HR), perceived exertion (RPE), and measuring it with accelerometers has implications for training and ensuring physical readiness of recruits. Eleven (7 male and 4 female) civilians (21.

So is it better than something else? Using the results of a random-effects meta-analysis to characterize the magnitude of an effect size as a percentile.

The characterization of an effect size is best made in reference to effect sizes found in the literature. A random-effects meta-analysis is the systematic synthesis of related effects from across a literature, producing an estimate of the distribution of effects in the population. We propose using the estimated mean and variance from a random-effects meta-analysis to inform the characterization of an observed effect size.

Developing partnerships for academic data science consulting and collaboration units.

Data science consulting and collaboration units (DSUs) are core infrastructure for research at universities. Activities span data management, study design, data analysis, data visualization, predictive modelling, preparing reports, manuscript writing and advising on statistical methods and may include an experiential or teaching component. Partnerships are needed for a thriving DSU as an active part of the larger university network.

Influence of Substituents on the Vectorial Difference Static Dipole Upon Excitation in Synthetic Bacteriochlorins.

Organic dye aggregates have been shown to exhibit exciton delocalization in natural and synthetic systems. Such dye aggregates show promise in the emerging area of quantum information science (QIS). We believe that the difference in static dipole (Δ) is an essential dye parameter in the development of molecular QIS systems.

Effects of Dye Addition on the Rheological Properties of Aqueous Polymer Solutions.

In many commercial applications, polymer-dye interactions are frequently encountered from food to wastewater treatment, and while shear rheology has been well characterized, the extensional properties are not well known. The extensional viscosity η and relaxation time λ are the extensional rheological parameters that provide valuable insights into how aqueous polymers respond during deformation, and this study investigated the effect of dyes on the extensional rheology of three different aqueous polymer solutions (e.g.
