Women Physical Activity and its Effective Factors Using a Social-Ecological Model [PDF]

open access: yes
Background: Physical activity is a health indicator that prevents many health problems as obesity and cardiovascular disease. The social-ecological model (SEM), is a suitable model for design and implementation to promotion of health programs. The aim of

Change in Depression, Confidence, and Physical Function Among Older Adults With Mild Cognitive Impairment

open access: yes, 2019
Background and Purpose Nearly a quarter of those in the US over age 71 experience mild cognitive impairment (MCI). Persons with MCI (PwMCI) battle depression and progressive disengagement from daily activities, which contribute to participation ...

Optical nonclassicality test based on third-order intensity correlations [PDF]

open access: yes, 2018
We develop a nonclassicality criterion for the interference of three delayed, but otherwise identical, light fields in a three-mode Bell interferometer.

Reconstructing enzyme evolution by protein engineering

open access: yesFEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Decoding the dynamic extracellular matrix in cancer—3D models and bioscaffolds rewire the rules of tumor progression

open access: yesFEBS Letters, EarlyView.
Cancer progression is regulated by the dynamic matrix code of the tumor microenvironment, which influences cellular behavior and disease development. Importantly, matrix remodeling in three‐dimensional cancer models more accurately reflects in vivo conditions compared to conventional two‐dimensional systems.

On Single Well Forced Gradient Tracer Tests: Implications of Aquifer Physical Heterogeneity and Tracer Behaviour [PDF]

open access: yes, 2010
Single well forced gradient tracer tests are a potential cost-effective approach to estimate in situ aquifer contaminant fate and transport parameters for use in natural attenuation assessments and remediation schemes.

Trans-Contextual Model Predicting Change in Out-of-School Physical Activity : A One-Year Longitudinal Study

open access: yes, 2021
The aim of the current study was to test the long-term predictive validity of the trans-contextual model in accounting for variance in adolescents’ out-of-school physical activity measured by self-report and accelerometer based-devices over a one-year ...

Network divergence analysis identifies adaptive gene modules and two orthogonal vulnerability axes in pancreatic cancer

open access: yesMolecular Oncology, EarlyView.
Tumors contain diverse cellular states whose behavior is shaped by context‐dependent gene coordination. By comparing gene–gene relationships across biological contexts, we identify adaptive transcriptional modules that reorganize into distinct vulnerability axes.

Hybrid Model Representation of a TLP Including Flexible Topsides in Non-Linear Regular Waves

open access: yesEnergies, 2014
The rising demand for renewable energy solutions is forcing the established industries to expand and continue evolving. For the wind energy sector, the vast resources in deep sea locations have encouraged research towards the installation of turbines in ...
