Addressing a problem of Fredman and Willard, we implement fusion trees in deterministic linear space using AC0 instructions only.

In a recent forum article, Dan Needleman and Jan Brugues argue that, despite the astonishing advances in cell biology, a fundamental understanding of even the most well-studied subcellular biological processes is lacking.(1) This lack of understanding is evidenced by our inability to make precise predictions of subcellular and cellular behaviors. They suggest that to achieve such an understandi...

work in the field of new PET-image–derived indices within the context of therapy response prediction and prognosis. Our recent article (1) was concerned with the physiologic reproducibility of such tumor-derived indices based on uptake heterogeneity features. The objective of the work was to provide support for the eventual introduction of these heterogeneity parameters into clinical use. The p...

Decision-making often involves choices between different stimuli, each of which is associated with a different physical action. A growing consensus suggests that the brain makes such decisions by assigning a value to each available option and then comparing them to make a choice. An open question in decision neuroscience is whether the brain computes these choices by comparing the values of sti...

Genetic evaluation systems like PIGBLUP use information on the performance of pigs along with environmental and management factors to derive Estimated Breeding Values (EBVs) for each animal. In contrast to the observed performance of an animal, EBVs are not expressed in absolute values but are expressed as a difference from a base value. This base often consists of the oldest animals included i...

Measurements using the finely segmented EM Calorimeter in PHENIX are presented. The issue of whether these are sufficient to claim discovery of the Quark Gluon Plasma is discussed. The " gold-plated " signature for the discovery of the Quark Gluon Plasma and the proof of " deconfinement " is the suppression of J/Ψ due to " Debye screening " which dissociates the bound pair of c − ¯ c quarks. [ ...

The question of lasers' exclusivity, as well as the degree of influence of special properties of low-intensity laser illumination (LILI), such as coherence, polarity and monochromaticity, on the effectiveness of low level laser therapy (LLLT) continues to cause arguments. The study analyzes publications from 1973 to 2016, in which laser and conventional light sources are compared, and the follo...

QMA (Quantum Merlin Arthur) is the class of problems which, though potentially hard to solve, have a quantum solution which can be verified efficiently using a quantum computer. It thus forms a natural quantum version of the classical complexity class NP (and its probabilistic variant MA, Merlin-Arthur games), where the verifier has only classical computational resources. In this paper, we stud...
