We prove the following result: Theorem. Every algebraic distributive lattice D with at most א1 compact elements is isomorphic to the ideal lattice of a von Neumann regular ring R. (By earlier results of the author, the א1 bound is optimal.) Therefore, D is also isomorphic to the congruence lattice of a sectionally complemented modular lattice L, namely, the principal right ideal lattice of R. F...

We construct an Identity-Based Key Encapsulation Mechanism (IBKEM) in a generic “leveled” multilinear map setting and prove its security under multilinear decisional Diffie-Hellmanin assumption in the selective-ID model. Then, we make our IB-KEM translated to the GGH framework, which defined an “approximate” version of a multilinear group family from ideal lattices, and modify our proof of secu...

We study well-rounded lattices which come from ideals in quadratic number fields, generalizing some recent results of the first author with K. Petersen [8]. In particular, we give a characterization of ideal well-rounded lattices in the plane and show that a positive proportion of real and imaginary quadratic number fields contains ideals giving rise to well-rounded lattices.

emergency departments (eds) are the most challenging ward with respect to patient delay. the goal of this study is to present strategies that have proven to reduce delay and overcrowding in eds. in this review article, initial electronic database search resulted in a total of 1006 articles. thirty articles were included after reviewing full texts. inclusion criteria were assessments of real pat...

Quotient Image (QI) algorithm has been widely used in face recognition and rerendering under varying illumination conditions. One of the inaccuracies of QI algorithm is the assumption of ‘‘Ideal Class’’, that all faces have the same surface normal (3D shape). However, in practice this assumption is often not true. To reduce the inaccuracy, the Non-Ideal Class Non-Point Light source QI (NIC-NPL-...

We extend the dynamic item response theory model of Martin and Quinn (2002) by including information about the court of origin and the opinion writer using a dynamic item response theory (IRT) model with a hierarchical prior. The model is estimated using Markov chain Monte Carlo methods. This approach not only provides better estimates of quantities of interest, such as judicial ideal points, i...
