Asymmetry of Caddo Ceramics from the Washington Square Mound Site: An Exploratory Analysis [PDF]

open access: yes, 2017
While pursuing a study of 3D geometric morphometrics for ceramic burial vessels that often articulate with the Native American Graves Protection and Repatriation Act (NAGPRA) from the ancestral Caddo region, there have been no shortage of potentially ...

Zonal shear and super-rotation in a magnetized spherical Couette flow experiment [PDF]

open access: yes, 2011
We present measurements performed in a spherical shell filled with liquid sodium, where a 74 mm-radius inner sphere is rotated while a 210 mm-radius outer sphere is at rest. The inner sphere holds a dipolar magnetic field and acts as a magnetic propeller

Classification of continuous vertical ground reaction forces [PDF]

open access: yes, 2014
The aim of this study is to assess and compare the performance of com- monly used hierarchical, partitional (k-means) and Gaussian model-based (Expectation-Maximization algorithm) clustering techniques to appropriately identify subgroup patterns within ...

Reducing Cement Contents of Paving Blocks by Using Mineral Waste and by-Product Materials [PDF]

open access: yes, 2014
In the production of conventional paving blocks, it is usual to use a minimum of 210  kg/m3 of cement. However, when portland cement is produced, it impacts negatively on the environment due to carbon dioxide emissions. Therefore, this paper investigates

Effects of adult dysthyroidism on the morphology of hippocampal neurons. [PDF]

open access: yes, 2013
This study investigates the effect of thyroid hormones on the morphology of hippocampal neurons in adult rats. Hypo- and hyperthyroidism were induced by adding 0.02% methimazole and 1% l-thyroxine, in drinking water from 40 days of age, respectively ...

One-dimensional vs. two-dimensional based features: Plant identification approach [PDF]

open access: yes, 2017
The number of endangered species has been increased due to shifts in the agricultural production, climate change, and poor urban planning. This has led to investigating new methods to address the problem of plant species identification/classification. In

Frequency responses of age-structured populations: Pacific salmon as an example

open access: yes, 2010
Increasing evidence of the effects of changing climate on physical ocean conditions and long-term changes in fish populations adds to the need to understand the effects of stochastic forcing on marine populations.
