Single-Molecule Carbon Nanotube Field-Effect Transistors for Genomic Applications

Single-molecule carbon nanotube-based field-effect transistors are promising all-electronic devices for probing interactions of various biological and chemical molecules at the single- molecule level. Such devices consist of point-functionalized carbon nanotubes which are charge sensitive in the vicinity of a generated defect on the nanotube sidewall. Of particular interest is the characterization of the kinetic rates and thermodynamics of DNA duplex formation through repeated association (hybridization) and dissociation (melting) events on timescales unmatched by conventional single-molecule methods. In this work, we study the kinetics and thermodynamics of DNA duplex formation with two types of single-walled nanotubes: CVD-grown and solution-processed. In both assessments, we are able to extract kinetic and thermodynamic parameters governing the hybridization and melting of DNA oligonucleotides. In the latter case, devices are spun onto a wafer surface from an organic suspension, revealing consistent electrical characteristics. Significant effort is made to expand this work to wafer-level, in an effort to make the fabrication manufacturable

Purchase Behaviors During Emergencies: Exploratory Analyses and Predictive Models

In this study, we distinguish between traditional emergency events (i.e., those that occur frequently) and novel emergency events (i.e., those that occur rarely in one’s lifetime). We examine consumers’ shopping behaviors during both types of emergency events. Using data from a U.S. supermarket chain, we answer three research questions. First, we conduct multiple cluster analyses and identify three distinct shopping behaviors during emergency events, namely strategic, routine, and stocking. Second, we examine how consumers change their shopping behaviors toward novel emergency events and find that majority of consumers continue to engage in routine shopping behaviors. Third, we examine how to predict shopping behaviors before emergency events and show that all three types of shopping behaviors can be predicted with reasonable levels of accuracy based on consumers’ spending before emergency events

Effectiveness Of Relationship Marketing Tactics In A University Setting

We test the correlation between student perception of three university relationship-building tactics - commercial friendships, preferential treatment, and tangible rewards - with university student satisfaction. We also test whether two student characteristics - enduring involvement with education and sense of entitlement - have a moderating effect on the aforementioned relationship between university relationship-building behaviors and student satisfaction. Results revealed positive correlations between perceived relationship tactics and overall satisfaction. Correlations between the relationship-building behaviors and satisfaction were also greater among high-involvement students than among their lesser-involved cohorts. Students who felt a sense of entitlement were more likely to believe that they were recipients of relationship-building behaviors, but they didn’t always appreciate them more than students who felt less entitled

1 versus 1 in football after 20 years

The new millennium was marked by the epic of the legendary Barcelona of Guardiola, the coach who revolutionized the world of football with his tiki taka. This game is made of fast ball exchanges, continuous changes of position and search for the free space to occupy but it has downgraded the dribbling, that is one of the main technical skills of the game of football. Starting from football schools, it almost seems that 1vs1 has been set aside to favour other fundamental techniques, so we find ourselves in a period where fewer and fewer players take the responsibility to try a bet in 1v1, but prefer to pass the ball to the closest mate. This research has analysed the goals of final stages of two World cup (the most football event),20 years later, Russian 2018 and France 1998 and has demonstrated that in 20 years, the incidence of goals scored after a dribble influenced by the action has decreased of 10%. From the round of 16 onwards of Russian 2018 have been scored 47 goals, whose 8 after an influential dribbling (17%). In France 1998 have been scored 45 goals, 12 with an influential dribbling (27%). The world of football should be open to new revolutions, without ignore none of basic skills to a player's growth

Selecting Link Resolver and Knowledge Base Software: Implications of Interoperability

Link resolver software and their associated knowledge bases are essential technologies for modern academic libraries. However, because of the increasing number of possible integrations involving link resolver software and knowledge bases, a library’s vendor relationships, product choices, and consortial arrangements may have the most dramatic effects on the user experience and back-end maintenance workloads. A project team at a large comprehensive university recently investigated link resolver products in an attempt to increase efficiency of back-end workflows while maintaining or improving the patron experience. The methodology used for product comparison may be useful for other libraries

1 vs 1 in the major European football championship

The new millennium was marked by the epic of the legendary Barcelona of Guardiola, the coach who revolutionized the world of football with his tiki taka The search for this game made of fast ball exchanges, continuous changes of position and search for free space to occupy, however, has downgraded what is one of the main technical skills of the game of football, the dribbling. Starting with football schools Pedagogical value of the body and physical activity in childhood. 1vs1 has been set aside to favour other technical fundamentals, so we are in a period where fewer and fewer players take responsibility for trying a game in 1vs1, but prefer to pass the ball to their closest partner (Giordano L. et all 2019). This second study has analysed the scorer rankings of the top 4 European championships (Serie A, Premier League, Spanish League, Bundesliga) of the 2009/2010 and 2017/2018 seasons, taking into account not only the total goals, but also the average shots per game and the average dribbling per game
