Direct Computation of the Degree 4 Gopakumar -Vafa Invariant on a Calabi -Yau 3 -Fold
… Euler characteristic is equal up to sign to the degree 4 BPS (Gopakumar-Vafa) invariant of local P 2, a (noncompact) Calabi-Yau 3-fold. This is a new result verifying an instance of conjecture motivated by physics.

From String to Structure: Graph Threading for Physical Assembly
… proving NP-hardness for graphs of maximum degree 4, tractability for degree 3, and giving exact and approximation algorithms for restricted variants, including rectangular grid graphs. Finally, we turn from theory to fabrication, proposing multi-configuration threading—a new approach for …

Unification and equation solving in nilpotent groups and monoids
… restricted class of diophantine equations of degree k. The unification problem for the theories of nilpotent groups of class Z5 is shown to be undecidable. This improves the result of Romankov [60] who showed it for class Z 9. The result is established by reducing the problem to that of …

What Kind of Food Is an Apple? Children's Script, Taxonomic, and Evaluative Categories of Food
… results showed that 7-year-olds and to a lesser degree 4-year-olds can selectively use categories to make inductive inferences about foods. Evaluative categories were revisited in Experiments 6--8. The findings were that 4- and 7-year-olds form evaluative categories and can selectively use them …

On the foldability of rigid origami
Among the techniques of forming the geometry of a reconfigurable and programmable matter, origami (the art of paper folding) and kirigami (paper folding with cutting) are especially appealing, as they are effective tools for transforming simple two-dimensional materials into complex …

Gromov-Witten theory in dimensions two and three
… the Hurwitz locus HG C Mg of curves admitting a degree 4 cover of P1 having monodromy group G. We compute the generating functions for these integrals and write them as a trigonometric expression summed over the positive roots of the E6 and D4 root systems respectively. As an application, we …

An examination of the experience of individuals, from different vocational and academic entry routes, on a B.A. Educational Studies degree and in subsequent postgraduate study or employment
… a single cohort of students on an undergraduate degree – the B.A. Educational Studies – at the University of Hull. It investigates their entry profiles, their progress on the degree and the impact their studies have had on their postgraduate lives.The research has been informed by a range of …

A study of graduates from the Master of Arts in Adult Education program at Federal City College
… Federal City College without the undergraduate degree were compared with graduates who entered the program with the undergraduate degree to determine why the students entered the program, what the students brought to the program, how the students performed in the program, and how they were …
