Nucleon Decay Matrix Elements from Lattice QCD [PDF]

, 2001
We present a GUT-model-independent calculation of hadron matrix elements for all dimension-six operators associated with baryon number violating processes using lattice QCD.

Top-k Querying of Unknown Values under Order Constraints [PDF]

, 2017
Many practical scenarios make it necessary to evaluate top-k queries over data items with partially unknown values. This paper considers a setting where the values are taken from a numerical domain, and where some partial order constraints are given over

Solving Connectivity Problems Parameterized by Treedepth in Single-Exponential Time and Polynomial Space [PDF]

, 2020
A breakthrough result of Cygan et al. (FOCS 2011) showed that connectivity problems parameterized by treewidth can be solved much faster than the previously best known time ?^*(2^{?(twlog tw)}). Using their inspired Cut&Count technique, they obtained ?^*(

Classification of partial discharge severities of ceramic insulators based on texture analysis of UV pulses

High Voltage, 2021
Inspection of partial discharge before contamination flashover is of great importance for preventing exterior insulation accidents. In this study, a new method for identification of discharge severities is proposed.

Hyperspectral Imaging of Adaxial and Abaxial Leaf Surfaces as a Predictor of Macadamia Crop Nutrition

Plants, 2023
Tree crop yield is highly dependent on fertiliser inputs, which are often guided by the assessment of foliar nutrient levels. Traditional methods for nutrient analysis are time-consuming but hyperspectral imaging has potential for rapid nutrient ...

Semi-inclusive B Decays and Direct CP Violation in QCD Factorization [PDF]

, 2001
We have systematically investigated the semi-inclusive B decays B->MX, which are manifestations of the quark decay b->Mq, within the framework of QCD-improved factorization.

Turbocharging Treewidth Heuristics [PDF]

, 2017
A widely used class of algorithms for computing tree decompositions of graphs are heuristics that compute an elimination order, i.e., a permutation of the vertex set. In this paper, we propose to turbocharge these heuristics.

Ramsey-type graph coloring and diagonal non-computability [PDF]

, 2014
A function is diagonally non-computable (d.n.c.) if it diagonalizes against the universal partial computable function. D.n.c. functions play a central role in algorithmic randomness and reverse mathematics.

First draft genome assembly of the Argane tree (Argania spinosa) [PDF]

, 2018
Background: The Argane tree (Argania spinosa L. Skeels) is an endemic tree of southwestern Morocco that plays an important socioeconomic and ecologic role for a dense human population in an arid zone.

Exploring $\pp$ scattering in the $\1N$ picture [PDF]

, 1995
In the large $N_c$ approximation to $QCD$, the leading $\pp$ scattering amplitude is expressed as the sum of an infinite number of tree diagrams. We investigate the possibility that an adequate approximation at energies up to somewhat more than one $GeV$
