Reasoning with PCP-Nets

open access: yesJournal of Artificial Intelligence Research, 2021
We introduce PCP-nets, a formalism to model qualitative conditional preferences with probabilistic uncertainty. PCP-nets generalise CP-nets by allowing for uncertainty over the preference orderings. We define and study both optimality and dominance queries in PCP-nets, and we propose a tractable approximation of dominance which we show to be very ...

Robust PCPs of Proximity, Shorter PCPs, and Applications to Coding [PDF]

open access: yesSIAM Journal on Computing, 2004
We continue the study of the trade-off between the length of probabilistically checkable proofs (PCPs) and their query complexity, establishing the following main results (which refer to proofs of satisfiability of circuits of size $n$): 1. We present PCPs of length $\exp(o(\log\log n)^2)\cdot n$ that can be verified by making $o(\log\log n ...

Smooth and Strong PCPs

open access: yescomputational complexity, 2021
Probabilistically checkable proofs (PCP) play an important role in the area of randomized algorithms. Intuitively, such a proof can be checked by a randomized algorithm whose randomness of the read number of bits of the proof is bounded in some way. Acceptance of correct, respectively, rejection of false proofs must happen with very high probability ...

Ebola Virus Maintenance: If Not (Only) Bats, What Else?

open access: yesViruses, 2018
The maintenance mechanisms of ebolaviruses in African forest ecosystems are still unknown, but indirect evidences point at the involvement of some bat species. Despite intense research, the main bat-maintenance hypothesis has not been confirmed yet.

The Quantum PCP Conjecture

open access: yesCoRR, 2013
The classical PCP theorem is arguably the most important achievement of classical complexity theory in the past quarter century. In recent years, researchers in quantum computational complexity have tried to identify approaches and develop tools that address the question: does a quantum version of the PCP theorem hold?

Efectos y beneficios de la Planificación Centrada en la Persona (PCP) en las personas adultas con discapacidad intelectual, en las organizaciones y en la comunidad. Estado de la cuestión

open access: yesSiglo Cero, 2018
Desde hace más de tres décadas se ha venido proponiendo la aplicación de una metodología denominada Planificación Centrada en la Persona (PCP), que parte de los principios de normalización e inclusión, y en la que la persona con discapacidad intelectual ...

Quantitative PCR to Discriminate Between Pneumocystis Pneumonia and Colonization in HIV and Non-HIV Immunocompromised Patients

open access: yesFrontiers in Microbiology, 2021
Pneumocystis pneumonia (PCP) is an opportunistic infection that commonly occurs in immunocompromised individuals. A definite diagnosis of PCP can be made only when the organism is identified in a respiratory specimen.

Two frizzled planar cell polarity signals in the Drosophila wing are differentially organized by the Fat/Dachsous pathway. [PDF]

open access: yesPLoS Genetics, 2011
The regular array of distally pointing hairs on the mature Drosophila wing is evidence for the fine control of Planar Cell Polarity (PCP) during wing development.
