TL;DR: It is suggested that the main cause for velocity amplification is related to resonant shape fluctuation, which can be illustrated by periodically deforming and relaxing the drop at low frequencies.
Abstract: The motions of liquid drops of various surface tensions and viscosities were investigated on a solid substrate possessing a gradient of wettability. A drop of any size moves spontaneously on such a surface when the contact angle hysteresis is negligible; but it has to be larger than a critical size in order to move on a hysteretic surface. The hysteresis can, however, be reduced or eliminated with vibration that allows the drop to sample various metastable states, thereby setting it to the path of global energy minima. Significant amplification of velocity is observed with the frequency of forcing vibration matching the natural harmonics of drop oscillation. It is suggested that the main cause for velocity amplification is related to resonant shape fluctuation, which can be illustrated by periodically deforming and relaxing the drop at low frequencies.

TL;DR: A brief overview of the recent research achievements in the field of life-cycle engineering for civil and marine structural systems is presented in this paper, where the authors indicate future dire threats of structural degradation due to ageing, mechanical stressors, and harsh environment.
Abstract: Structural systems are under deterioration due to ageing, mechanical stressors, and harsh environment, among other threats Corrosion and fatigue can cause gradual structural deterioration Moreover, natural and man-made hazards may lead to a sudden drop in the structural performance Inspection and maintenance actions are performed to monitor the structural safety and maintain the performance over certain thresholds However, these actions must be effectively planned throughout the life-cycle of a system to ensure the optimum budget allocation and maximum possible service life without adverse effects on the structural system safety Life-cycle engineering provides rational means to optimise life-cycle aspects, starting from the initial design and construction to dismantling and replacing the system at the end of its service life This paper presents a brief overview of the recent research achievements in the field of life-cycle engineering for civil and marine structural systems and indicates future dire

TL;DR: The Psychology of Non-Conscious Bias as mentioned in this paper shows that implicit negative attitudes and stereotypes shape how medical professionals evaluate and interact with minority group patients, which contributes to racial and ethnic disparities in health care, and that training in cultural competence should incorporate research on the psychology of non-conscious stereotyping and prejudice.
Abstract: Medical Education 2011: 45: 768–776 Context Non-conscious stereotyping and prejudice contribute to racial and ethnic disparities in health care. Contemporary training in cultural competence is insufficient to reduce these problems because even educated, culturally sensitive, egalitarian individuals can activate and use their biases without being aware they are doing so. However, these problems can be reduced by workshops and learning modules that focus on the psychology of non-conscious bias. The Psychology of NON-Conscious Bias Research in social psychology shows that over time stereotypes and prejudices become invisible to those who rely on them. Automatic categorisation of an individual as a member of a social group can unconsciously trigger the thoughts (stereotypes) and feelings (prejudices) associated with that group, even if these reactions are explicitly denied and rejected. This implies that, when activated, implicit negative attitudes and stereotypes shape how medical professionals evaluate and interact with minority group patients. This creates differential diagnosis and treatment, makes minority group patients uncomfortable and discourages them from seeking or complying with treatment. Pitfalls in Cultural Competence Training Cultural competence training involves teaching students to use race and ethnicity to diagnose and treat minority group patients, but to avoid stereotyping them by over-generalising cultural knowledge to individuals. However, the Culturally and Linguistically Appropriate Services (CLAS) standards do not specify how these goals should be accomplished and psychological research shows that common approaches like stereotype suppression are ineffective for reducing non-conscious bias. To effectively address bias in health care, training in cultural competence should incorporate research on the psychology of non-conscious stereotyping and prejudice. Training in Implicit Bias Enhances Cultural Competence Workshops or other learning modules that help medical professionals learn about non-conscious processes can provide them with skills that reduce bias when they interact with minority group patients. Examples of such skills in action include automatically activating egalitarian goals, looking for common identities and counter-stereotypical information, and taking the perspective of the minority group patient.

TL;DR: In this article, the authors demonstrate that ratios of the abundances of n-alkanes provide a new and efficient way of reconstructing past peatland surface moisture change, and find strong correlations among nalkane indices, humification indices and testate amoebae-inferred water table depths from a single core.
