In a homogenous and isotropic material, the location of the neutral axis coincides with the location of the centroid of the beam. Wood is anisotropic, meaning that it has different properties in different directions. It is also non-homogenous, meaning that the beam exhibits different properties at different locations throughout its...
For wood beams, it is often assumed that the neutral axis is located at the centroid of the
beam. The neutral axis of isotropic, homogeneous materials is located at the centroid of the
material, but wood is neither isotropic nor homogeneous. The varying grain patterns and
knots located throughout wood...
It is commonly accepted that for the analysis of wood beams, the neutral axis coincides with the centroid of the beam. Although this assumption is used in analysis, wood is not an isotropic material, as it has different elastic properties in the tangential, radial and longitudinal directions, nor is it...
Profile Hidden Markov Models utilize the information stored in a multiple sequence alignment such as its residues and conserved regions to assign probabilities at each column. This indicates areas in the sequences where similar functionality is observed. These probability weights are then combined to assign a sequence score, which is...
Instance segmentation, the classification and localization of objects in an image, is a problem in cellular biophysics due to the physiological relevance of cell morphology. Particularly, cancer cells migrate in tissue space by changing their body shape similarly to how humans extend their limbs to swim through water. Monitoring such...
While seemingly harmless, stereotypes can play a significant role in prejudice and discrimination. In two studies, we examined stereotypes of Asian American women and how they may vary with different clothing types. We used a mixed factorial design with a sample of college students from a U.S. university. In the...
It has been demonstrated that dogs form attachment bonds to their owners and that these attachments can be classified and described in ways that are analogous to attachments found between human infants and their mothers. While a secure attachment to a parent has been shown to improve problem-solving abilities in...
The issue of global climate change and possible remedies has been debated between national governments since the 1970s. While some countries have adopted aggressive measures to address the issue, others have lagged in their efforts. The United States, as a key player in global climate change conferences, has focused its...
Vibrio cholerae is the causative agent of cholera, a serious diarrheal disease in developing countries. V. cholerae has a unique redox driven respiration-linked sodium pump, Na⁺ translocating NADH:quinone oxidoreductase (NQR). Several reports previously showed that NQR plays an important role in virulence, metabolism, and sodium homeostasis of V. cholerae. This...
The emergence of high explosives on the battlefield can be defined both literally and figuratively as a seismic event in the landscape of modern warfare. High explosives first came into common use in war in 1914. By the end of World War I just four years later, more than 2.5...
