Timing and pattern of valley excavation, Le Sueur River, south-central Minnesota, USA
… is responding to approximately 70 meters of base level fall that occurred 13,400 years ago (11,500 radiocarbon years before present), when glacial River Warren carved the Minnesota River valley. The carving of the Minnesota River valley led to widespread incision on Minnesota River tributaries …

Drivers of reproductive variability in Vaccinium cespitosum and vaccinium vitis-idaea in northeastern Minnesota
… than populations that have not been managed, as land management has been shown to positively impact stem, flower, and fruit production. Additionally, both species are partially clonal and are capable of sexual or clonal reproduction. In populations with high clone densities, the likelihood of …

Long-Term Hydrologic Sustainability of Calcareous Fens Along Glacial Lake Agassiz Beach Ridges, Northwestern Mn
… that support several threatened species of plants that evolved to thrive in these geochemical conditions. Fifty-three of Minnesota’s nearly 300 identified calcareous fens are located in the Glacial Lake Agassiz beach ridge complex in northwestern Minnesota. Each of these fens is located …

Immediate Deflection Calculations Of Transition And Cracked Prestressed Concrete Sections
… are tensioned/pulled and then concrete is cast around the strands in the form. Once the concrete has set, the strands are cut, and the member is put into compression from the pre-tensioned strands. Concrete is classified as uncracked, transition, and cracked based on the stress in a critical …

A method for correlation of gravestone weathering and air quality (SO2), West Midlands, UK
… SO2 beginning in the 1960s however the direct measurement of air quality prior to 1960 is lacking and only anecdotal notations exist. Proxy records including lung tissue samples, particulates in sediments cores, lake acidification studies and gravestone weathering have all been used to …

Robot-Assisted Physical Therapy for cognition and motor skill enhancement in people with dementia.
… This study investigates the efficacy of robot-assisted therapies to improve cognition and motor skills for individuals affected with dementia.The primary objective of this research is to evaluate whether robot-assisted therapies, facilitated by the NAO robot, can improve physical functioning, …

Left-handed BCI - examining effects of handedness and hand dominance on EEG grasp classification
… signals from the brain, and is commonly used in cases where other sensing methods are difficult or impossible. This method of collecting brain signal data has been shown, when used in conjunction with Electromyography (EMG) data, to be capable of classifying fine hand movements with a high degree …

Estimating File Compressibility Using File Extensions
… compression systems were designed with the assumption that files with the same filename extension will compress roughly to the mean compression ratio (the ratio of compressed size to original size) of some set of files with the same extension. This implies that the compression ratio …

Characterizing Provenance of the Late Wisconsinan Rainy Lobe Using Fine-Fraction Geochemistry and Detrital Zircon Geochronology
… in southwestern Minnesota well prior to the Last Glacial Maximum (ca. 27-30 ka BP) and retreated into Ontario by 17.9 ka BP. This till exhibits dramatic spatial and temporal changes in provenance from the Hewitt till of SW Minnesota to the Independence till in the NE. Two models have been …

Ravine alluvial fans as records of landscape change in the Le Sueur River Basin, southern Minnesota
Ravine alluvial fans in the Le Sueur River Basin (LSRB) of south-central Minnesota record post-glacial Holocene changes and modern anthropogenic disturbances to land cover and hydrology in high-latitude watersheds. Seventy meters of base-level drop at the end of the last glaciation initiated …

A machine learning approach to predict emotional arousal and aggressive driving from EDA and heart rate signals
Aggressive driving behaviors, such as sudden acceleration and hard braking, abrupt steering, significantly increase the risk of road accidents, especially among young drivers. This study aims to predict aggressive driving behavior and emotional arousal using physiological signals, Electrodermal …

An Investigation of Ni and Cu Isotopic Fractionation in Basal Duluth Complex Cu-Ni-PGE Mineralization, Northeastern Minnesota
… western margin of the Duluth Complex in northeastern Minnesota. Previous studies have demonstrated a notable fractionation of 60Ni and 58Ni in terrestrial materials, including both primary and secondary phases, with a total range of up to 2.1 ‰. Other work has indicated a fractionation of 65Cu …

The geologic history of Lake of the Woods, Minnesota, reconstructed using seismic-reflection imaging and sediment core analysis
The history of glacial Lake Agassiz is complex and has intrigued researchers for over a century. Over the course of its ~5,000 year existence, the size, shape, and location of Lake Agassiz changed dramatically depending on the location of the southern margin of the Laurentide Ice Sheet (LIS), the …

Geology and petrogenesis of the Tuscarora Intrusion of the Duluth Complex, Gillis Lake 7.5’ quadrangle, northeastern Minnesota
… is a layered mafic intrusion located at the base of the 1.1 Ga Duluth Complex in northeastern Minnesota. Detailed field mapping (1:12,000) and follow-up petrographic and geochemical analyses were conducted to evaluate the troctolitic igneous stratigraphy of the Tuscarora Intrusion, as well as …

Experimentally generated partition coefficients for the first-row transition elements during eclogite partial melting at three gigapascals
… Subduction results in the reinjection of basaltic crust into the mantle, which is metamorphosed into a rock called eclogite. The extent of lithological heterogeneity has implications for the rate of convective stirring and chemical homogenization of the mantle but is not well-constrained. …

U-Pb geochronology of the Duluth Complex and related hypabyssal intrusions: investigating the emplacement history of a large multiphase intrusive complex related to the 1.1 Ga Midcontinent Rift.
… the Duluth Complex and related intrusions associated with the 1.1 Ga Midcontinent Rift in NE Minnesota. They did not, however, resolve differences in emplacement ages within and between major intrusive units due to a small number of dated samples. New high-precision U-Pb baddeleyite and …
