We carefully examine the negative refractive index slab perfect lens theory by Pendry and point out an inconsistency that can be resolved. As a result, we find negative index slabs do not amplify or enhance evanescent waves and therefore they do no...
We obtain expressions for the shear and the vorticity tensors of perfect-fluid spacetimes, in terms of the divergence of the Weyl tensor. For such spacetimes, we prove that if the gradient of the energy density is parallel to the velocity, then eithe...
The aim of this note is to provide a reduction of the Exact Matching problem to the Top-$k$ Perfect Matching Problem. Together with earlier work by El Maalouly, this shows that the two problems are polynomial-time equivalent. The Exact Matching Pro...
In this paper, we consider the problem of answering count queries for genomic data subject to perfect privacy constraints. Count queries are often used in applications that collect aggregate (population-wide) information from biomedical Databases (DB...
A minimal perfect hash function (MPHF) maps a set of n keys to {1, ..., n} without collisions. Such functions find widespread application e.g. in bioinformatics and databases. In this paper we revisit PTHash - a construction technique particularly de...
"Untitled" (Perfect Lovers) is the title of two different artworks created by Félix González-Torres (or Felix Gonzalez-Torres). Each of the artworks consists
The past perfect form of have is had had (had + past participle form of have). The past perfect tense is used when we are talking about the past and want to refer back to an earlier past time.
Back when I was doing pilates/yoga classes at Equinox every week I noticed that ALL the girlies in the class always had perfect nails. I'm wondering how you all manage to do it. Is it just that you're...
A Perfect Circle is an American rock supergroup formed in Los Angeles, California, in 1999 by guitarist Billy Howerdel and Tool vocalist Maynard James
For most problems pertaining to perfect matchings, one may restrict attention to matching covered graphs - that is, connected nontrivial graphs with the property that each edge belongs to some perfect matching. There is extensive literature on these...
# Where to Buy Your Perfect iPhone 15 Case with Card Holder If you’ve recently gotten your hands on the iPhone 15, you might be on the hunt for the perfect case. With so many options available, it ...
Achieving The Perfect 10 is a television documentary film released on CNN on August 10, 2003 about young girls training gymnastics at the highly competitive
A parallel algorithm has perfect strong scaling if its running time on P processors is linear in 1/P, including all communication costs. Distributed-memory parallel algorithms for matrix multiplication with perfect strong scaling have only recently b...
An extended $1$-perfect trade is a pair $(T_0,T_1)$ of two disjoint binary distance-$4$ even-weight codes such that the set of words at distance $1$ from $T_0$ coincides with the set of words at distance $1$ from $T_1$. Such trade is called primary i...
