The interactions of chemical species with a solid surface play a role in many everyday applications such as heterogeneous catalysis, corrosion, and degradation reactions. Understanding the reaction kinetics and thermodynamics via rate constants and equilibrium constants, which require knowledge of the adsorbed species’ entropy, is essential for tuning these surface...
Most of today’s Internet of Things (IoT) applications assume that data will be moved offdevices into centralized cloud platforms. While existing IoT systems leverage cloud-based analytics for meaningful data reasoning, the assumption that data should always be moved off the devices is problematic. The amount of data to be moved...
In this study, we explored the relationships among gender, age, daily stressors, positive and negative affect, and neuroticism on cortisol outcomes in older men and women. We were particularly interested in whether variation in positive affect would have an effect on variation in negative affect and if this relationship would...
Transportation agencies continuously strive to improve driving quality and highway safety, which are both highly correlated with the level of smoothness of the road.

Obesity is a complex multifactorial disease resulting from excessive energy intake compared to energy expenditure. The excess energy is mostly stored as fat in enlarged adipocytes, but some lipids may infiltrate other organs such as the liver to form ectopic fat. Adipose tissue and ectopic fat produce and secrete a...
Pesticides benefit agriculture by increasing crop yield, quality, and security. However, pesticides may inadvertently harm bees, which are valuable as pollinators. Thus, candidate pesticides in development pipelines must be assessed for toxicity to bees.
Leveraging a data set of 382 molecules with toxicity labels from honey bee exposure experiments, we...
This thesis explores the differences in puppetted and teleoperation control of robotic hands, using the Asterisk test as a benchmark. Two hands were tested, including modified versions of the Model Q and Model Q developed by Yale's GRAB Lab. Small differences were observed between the puppetted and teleoperation control of...
Recent years have been marked with increasing rates of corporate scandals, environmental disasters, and unfair labor practices, drawing attention to the importance of corporate social responsibility (CSR). Despite increasing efforts in CSR, past research has shown increased levels of mistrust and skepticism from consumers towards business. Furthermore, the very issues...
The abilities of plant biologists to characterize the genetic basis of physiological traits are limited by their abilities to obtain quantitative data representing precise details of trait variation and mainly to collect this data on a high-throughput scale at low cost. Deep learning-based methods have demonstrated unprecedented potential to automate...
Deposition characteristics of magnesium silicate and calcium carbonate on a heated surface in cooling tower water using city water as make-up was investigated. Flow velocity, bulk temperature and calcium hardness were maintained constant at 5.3 ft/ sec, 95°F and 150 ppm as CaCO₃ respectively whereas surface temperature varied from 105°F...

Communication cannot be successful without the
cooperative listening response of an auditor. Auditors must
feel empowered to act as agents of change or their decisions
and actions cannot be influenced by the discourse. Their
every response depends upon their ability to perceive
themselves as potential mediators of change.

It is often perceived that late maturity of grape gives a more complex aroma
profile to Pinot noir wine, however, there is little understanding of the basic flavor
chemistry of grape maturity on wine aroma. The aroma contributing compounds in
Pinot noir were first identified by aroma extract dilution analysis...
