The profile inter‐unit reliability
(Wiley Periodicals, Inc.RAND Corporation, 2020-06)
To assess the quality of health care, patient outcomes associated with medical providers (eg, dialysis facilities) are routinely monitored in order to identify poor (or excellent) provider performance. Given the high stakes ...
A flat torus theorem for convex co‐compact actions of projective linear groups
(Wiley Periodicals, Inc.International Press, 2021-03)
In this paper, we consider discrete groups in PGLd(R) acting convex co‐compactly on a properly convex domain in real projective space. For such groups, we establish an analogue of the well‐known flat torus theorem for ...
A classroom‐ready activity on educational disparities in the United States
(APLUWiley Periodicals, Inc., 2021-07)
We present a classroom‐ready activity for high school or college students involving an investigation of a rich, multivariate data set concerning educational and demographic characteristics of K‐12 schools at the state level ...
Equilibrium concepts for time‐inconsistent stopping problems in continuous time
(University of British ColumbiaWiley Periodicals, Inc., 2021-01)
A new notion of equilibrium, which we call strong equilibrium, is introduced for time‐inconsistent stopping problems in continuous time. Compared to the existing notions introduced in Huang, Y.‐J., & Nguyen‐Huu, A. (2018, ...
Regularity bounds for twisted commutative algebras
(Cambridge University PressWiley Periodicals, Inc., 2020-04)
Let A be the twisted commutative algebra freely generated by d indeterminates of degree 1. We show that the regularity of an A‐module can be bounded from the first ⌊14d2⌋+2 terms of its minimal free resolution. This partially ...
The WYSIWYG compactification
(SpringerWiley Periodicals, Inc., 2021-03)
We show that the partial compactification of a stratum of Abelian differentials previously considered by Mirzakhani and Wright is not an algebraic variety. Despite this, we use a combination of algebro‐geometric and other ...
Eigenvalues of the Thurston operator
(AK PetersWiley Periodicals, Inc., 2020-09)
Let f:Ĉ→Ĉ be a postcritically finite rational map, and let Q(Ĉ) be the space of meromorphic quadratic differentials on Ĉ with simple poles. We study the set of eigenvalues of the pushforward operator f∗:Q(Ĉ)→Q(Ĉ). ...
Microporous scaffolds loaded with immunomodulatory lentivirus to study the contribution of immune cell populations to tumor cell recruitment in vivo
(Wiley Periodicals, Inc., 2020-01)
Metastases are preceded by stochastic formation of a hospitable microenvironment known as the premetastatic niche, which has been difficult to study. Herein, we employ implantable polycaprolactone scaffolds as an engineered ...
Cost minimization of repairable systems subject to availability constraints using efficient cuckoo optimization algorithm
(Wiley Periodicals, Inc., 2020-04)
System availability is a key element for any industry. System designers and operators try to do their best to maintain the required availability of the systems to avoid production stoppages. They set up and undertake ...
Translation surfaces and periods of meromorphic differentials
(Amer. Math. SocWiley Periodicals, Inc., 2022-04)
Let S$S$ be an oriented surface of genus g$g$ and n$n$ punctures. The periods of any meromorphic differential on S$S$, with respect to a choice of complex structure, determine a representation χ:Γg,n→C$chi :Gamma _{g,n} ...
