Adhesive System With Superior Drop And Creep Performance

This disclosure describes an adhesive system that imparts superior drop and creep performance properties to display screens used in devices. The adhesive system is suitable for devices in which the display screen are not horizontal (parallel to the ground), e.g., smart displays. The adhesive system combines an adhesive that has high drop performance with an adhesive that has superior creep resistance. The adhesive system includes portions of an adhesive liner that utilize the adhesive with high creep resistance and portions of the adhesive liner that utilize the adhesive with good drop performance to bond the display screen to the device

HyperCI: A higher order collective influence measure for hypernetwork dismantling

Network dismantling aims to scratch the network into unconnected fragments by removing an optimal set of nodes and has been widely adopted in many real-world applications such as epidemic control and rumor containment. However, conventional methods often disassemble the system from the perspective of classic networks, which have only pairwise interactions, and often ignored the more ubiquitous and nature group-wise interactions modeled by hypernetwork. Moreover, a simple network can't describe the collective behavior of multiple objects, it is necessary to solve related problems through hypernetwork dismantling. In this work, we designed a higher order collective influence measure to identify key node sets in hypernetwork. It comprehensively consider the environment in which the target node is located and its own characteristics to determine the importance of the node, so as to dismantle the hypernetwork by removing these selected nodes. Finally, we used the method to carry out a series of real-world hypernetwork dismantling tasks. Experimental results on five real-world hypernetworks demonstrate the effectiveness of our proposed measure

Credit Information in Earnings Calls

We develop a novel technique to extract credit-relevant information from the text of quarterly earnings calls. This information is not spanned by fundamental or market variables and forecasts future credit spread changes. One reason for such forecastability is that our text-based measure predicts future credit spread risk and firm profitability. More firm- and call-level complexity increase the forecasting power of our measure for spread changes. Out-of-sample portfolio tests show the information in our measure is valuable for investors. Both results suggest that investors do not fully internalize the credit-relevant information contained in earnings calls

Who is empathetic to the disaster you are going through? Mining Emotions (Empathy) in government and nonprofit responders’ tweets.

This project establishes and tests a measure of empathy in Twitter posts. The project intends to find evidence on whether community leaders and decision makers are showing compassion for the vulnerable communities undergoing natural disasters like Hurricane Florence through the online media like Twitter. The measure examines accounts from government agencies, nonprofit organizations and elected officials. First, I investigated how government agencies, nonprofit organizations, and elected officials adopted social media as their communication channel with the public. Second, I studied scholarly work on how social media platforms were used during crises, such as natural disasters. Then, I reviewed literature regarding compassion and empathy, and developed the instrument for properly measuring empathy. Finally, I chose Hurricane Florence as my target and content analyzed tweets from selected government agencies, nonprofit organizations, and elected officials. It turned out many contemporary practitioners used Twitter to keep citizens informed under a natural disaster. However, there is limited evidence showing empathy being part of the public-service package regarding Hurricane Florence. The study concludes with future research possibilities on empathy, as part of compassion, and community resilience building for climate and other disasters

Breast Pump for Low-Resource Settings

ME450 Capstone Design and Manufacturing Experience: Winter 2015Exclusive breastfeeding for the first six months of life is highly recommended by the United Nations Children’s Fund (UNICEF) and World Health Organization (WHO) based on its extraordinary range of benefits to both mothers and children. However, only 15% of infants aged 0 to 6 months in some least developed countries such as Nigeria and only 38% of infants worldwide are exclusively breastfed. The low breastfeeding rates are due in large part to a mother’s need to return to work, where mothers have no access to breastfeeding or expressing breast milk at work. Existing commercial grade and personal-use breast pumps are cost prohibitive and difficult to maintain for mothers in low-resource settings where clean water is a challenge and electricity is not available. Therefore, the team designed and prototyped a cheap, easy to clean, and easy to maintain breast pump for working mothers in low-resource settings.http://deepblue.lib.umich.edu/bitstream/2027.42/111327/1/09_Report.pd

Experimental demonstrations of high-Q superconducting coplanar waveguide resonators

We designed and successfully fabricated an absorption-type of superconducting coplanar waveguide (CPW) resonators. The resonators are made from a Niobium film (about 160 nm thick) on a high-resistance Si substrate, and each resonator is fabricated as a meandered quarter-wavelength transmission line (one end shorts to the ground and another end is capacitively coupled to a through feedline). With a vector network analyzer we measured the transmissions of the applied microwave through the resonators at ultra-low temperature (e.g., at 20 mK), and found that their loaded quality factors are significantly high, i.e., up to 10^6. With the temperature increases slowly from the base temperature (i.e., 20 mK), we observed the resonance frequencies of the resonators are blue shifted and the quality factors are lowered slightly. In principle, this type of CPW-device can integrate a series of resonators with a common feedline, making it a promising candidate of either the data bus for coupling the distant solid-state qubits or the sensitive detector of single photons.Comment: Accepted by Chinese Science Bulleti
