The I28 immunoglobulin (Ig)-like module of human cardiac titin, an elastic muscle protein, was used to cross-link acrylamide (AAm) copolymers into hybrid hydrogels. Cross-linking was accomplished through metal coordination bonding between terminal histidine tags (His tags) of the I28 module and metal-chelating nitrilotriacetic acid (NTA)-containing side chains on the copolymer. In solution, the...

Comparison of properties of three domains of titin, I1, I27, and I28, in a simple geometry-based model shows that despite a high structural homology between their native states different domains show similar but distinguishable mechanical properties. Folding properties of the separate domains are predicted to be diversified which reflects sensitivity of the kinetics to the details of native str...

This paper analyzes the Taiwan mechanism used nationwide for high school assignment starting in 2014. In mechanism, points are deducted from an applicant’s score, with larger penalties lower-ranked choices. Deduction makes a hybrid of Boston and deferred acceptance mechanisms. Our analysis sheds light on why Taiwan’s new has led to massive demonstrations it nonetheless remains use. (JEL D47, I2...

I thank Claire Black and Wei-Jang Huang for assistance in preparing this paper. I appreciate the comments of George Erickcek on a preliminary version of this paper. This paper was previously presented on November 20, 2009 at the 57th Annual Economic Outlook Conference of the Research Seminar in Quantitative Economics (RSQE) at the University of Michigan. I appreciate comments and questions for ...

Although in-person college access programs can be effective, less is known about whether low-cost and scalable virtual interventions achieve the same benefits. We evaluate two variants of a counseling program. Students randomly assigned to program felt more supported applying applied broadly four-year colleges, but were not likely accepted or enroll. analyze rich extensive survey data explore m...

A childhood intervention to improve the social skills and self-control of at-risk kindergarten boys in 1980s had positive impacts over life course: higher trust as adolescents; increased group membership, education, reduced criminality young adults; marriage employment adults. Using administrative data, we find this average yearly income by about 20 percent decreased transfers almost 40 percent...

Rubisco activase plays an important role in the regulation of CO(2) assimilation. However, it is unknown how activase regulates photosystem II (PSII) photochemistry. To investigate the effects of Rubisco activase on PSII photochemistry, we obtained transgenic tobacco (Nicotiana tabacum) plants with 50% (i7), 25% (i28), and 5% (i46) activase levels as compared to wild type plants by using a gene...
