Computers excel at performing quantitative and repetitive tasks quickly, but they struggle with qualitative tasks, such as handwriting recognition. This is because it is effectively impossible to program recognition of millions of different handwriting styles into one algorithm. However, with the advent of machine learning, computers can be trained to recognize unknown objects and characters by...

Giulio Ruffini,

The aim of this note is to provide some reference facts for LZW---mostly from Thomas and Cover \cite{Cover:2006aa} and provide a reference for some metrics that can be derived from it. LZW is an algorithm to compute a Kolmogorov Complexity estimate derived from a limited programming language that only allows copy and insertion in strings (not Turing complete set). Despite its delightful simplic...

The Edgebreaker compression [16, 11] is guaranteed to encode any unlabeled triangulated planar graph of t triangles with at most 1.84t bits. It stores the graph as a CLERS stringa sequence of t symbols from the set {C,L,E,R,S}, each represented by a 1, 2 or 3 bit code. We show here that, in practice, the string can be further compressed to between 0.91t and 1.26t bits using an entropy code. Th...

The evolutionary origins of vertebrate prion genes had remained elusive until recently when multiple lines of evidence converged to the proposition that members of the prion gene family represent an ancient branch of a larger family of ZIP metal ion transporters. (1) A follow-up investigation which explored the mechanism of evolution in more detail led to the surprising conclusion that the emer...

OBJECTIVE To describe the epidemiology of genital injuries caused by trouser zips and to educate both consumers and the caregivers of patients who sustain such injuries. PATIENTS AND METHODS The National Electronic Injury Surveillance System, a dataset validated to provide a probability sample of patients who present to emergency departments (EDs) in the USA with injuries, was analysed to cha...

Secondary growth and the development of woody tissue is a key process in the formation of woody biomass. The gene family of Class III HDZip genes has been shown in the herbaceous Arabidopsis model to play a central role in regulating polarity and vascular development. While Arabidopis is a poor model for investigating processes of wood formation, in this project all poplar Class III HDZip genes...

Class III HD-ZIP and KANADI gene family members have complementary expression patterns in the vasculature and their gain-of-function and loss-of-function mutants have complementary vascular phenotypes. This suggests that members of the two gene families are involved in the establishment of the spatial arrangement of phloem, cambium and xylem. In this study, we have investigated the role of thes...

PRIMARY LUNG DISEASE, the associated inflammatory response, and treatment with supplemental oxygen all result in the generation of increased amounts of reactive oxygen species (ROS), which can cause significant damage to the lung. The susceptibility of the lung to oxidative injury depends largely on the ability to upregulate protective ROS scavenging systems. Unfortunately, both intracellular a...

Text data modeling has been usually considered with Bernoulli or multinomial event models. Poisson distribution is considered inefficient for text information retrieval. In this work, we propose to incorporate the Zero Inflated Poisson model in the Generative Topographic Mapping algorithm. The modified algorithm is presented as a text document cluster extraction and visualization tool. Experime...

Real-time compression for primary storage is quickly becoming widespread as data continues to grow exponentially, but adding compression on the data path consumes scarce CPU and memory resources on the storage system. Our work aims to mitigate this cost by introducing methods to quickly and accurately identify the data that will yield significant space savings when compressed. The first level o...
