Monitoring of Colorectal Cancer Screening Adherence Among African American Patients of North Florida Community Health CentersNARA Subscribed
In the United States, colorectal cancer (CRC) mortality rates are higher in African Americans compared to non-Hispanic whites, partly due to advanced stage cancer diagnosis. Timely CRC screening helps to increase CRC early detection and survival in this population. The objective of this monitoring study was to survey African American patients of Community Health Centers (CHC) in north Florida and to monitor CRC screening adher...
The future of how we understand and manage ecosystems largely depends on direct and continuous observations that connect local territories to planetary processes. Latin America (LATAM: Mexico, Central and South America, and the Caribbean) hosts ecosystems critical for regulating global carbon, water, and energy cycles. However, persistent underinvestment in science and technology hampers the long‐term monitoring capacity neede...
Predicting rock strength anisotropy using a sensitivity-driven evolutionary polynomial regressionNARA Subscribed
The strength of anisotropic rocks remarkably depends on the orientation of stresses with respect to existing directional features in rocks such as foliation, bedding planes, and cleavages. While rock strength anisotropy is crucial for engineering design, experimental tests to obtain peak strengths of samples with several degrees of anisotropy and confining stresses are time-consuming and costly. Reliable and high-fidelity mode...
Native and non-native plant richness and diversity along an elevational gradient in the Ecuadorian AndesNARA Subscribed
Ecuador, recognized as a megadiverse country, faces growing threats from biological invasions, particularly in the mountainous ecosystems of the Andes. We described patterns of native and non-native plant richness and diversity along an elevational gradient (2,000–4,400 m a.s.l.) on the Tungurahua volcano, testing whether patterns of non-native plant diversity are consistent with directional environmental filtering along the g...
Beyond strength: dietary nitrate augments self-selected functional mobility after resistance training in middle-aged adultsNARA Subscribed
This study aimed to assess whether dietary nitrate supplementation with resistance training (RT) augments gait performance and functional mobility in inactive middle-aged and older adults. We hypothesized that combining nitrate-rich beetroot juice (BRJ) with RT would yield improvements in gait and functional mobility compared to RT with nitrate-depleted beetroot juice placebo (PLA) supplementation. In this 12-week, randomized,...
