D0L systems constitute the simplest and most widely studied type of Lindenmayer systems. They have the remarkable property of generating their language as a (word) sequence and, consequently, are very suitable for modeling growth properties. In this paper a new type of D0L systems is introduced, where the parallelism presented in L systems is combined with the paradigm of (Watson-Crick) complem...

Each variable X is a new, independent Uniform [0, 1] random number. For example, T = ∅ with probability 1−p, T = (∅, ∅) with probability p(1−p)2, and T = ((∅, ∅), ∅) with probability p2(1− p). The number of vertices N is equal to twice the number of left parentheses (parents) in the expression for T , plus one. Equivalently, N is twice the number of ∅s (leaves), minus one. It can be shown that ...

Description of task: The MNIST, a database of Handwritten Digit Classification, (possibly) the most famous dataset in the field of Machine Learning is studied using different classification techniques on it and did a comparative analysis to reproduce the best possible accuracy on it. The standard algorithms were improved by applying various techniques such as extracting features via feature ext...

Aerosol size distributions are presented for a winter intensive study at the Fresno Supersite. The size distributions were consistent with and predictive for continuous PM2.5 measured by beta attenuation. They varied temporally with respect to source type and intensity, with the smallest mean diameters associated with high NOx concentrations during weekday morning rush hours. Conversely, small ...

M. C. McCord J. W. Murdock B. K. Boguraev Two deep parsing components, an English Slot Grammar (ESG) parser and a predicate-argument structure (PAS) builder, provide core linguistic analyses of both the questions and the text content used by IBM Watsoni to find and hypothesize answers. Specifically, these components are fundamental in question analysis, candidate generation, and analysis of pas...

We describe our hunter-gartherer system for the NTCIR10 1CLICK-2 task. We inspire ourselves on the DeepQA framework looking to adapt it for the 1CLICK task. Several techniques can be integrated naturally in this framework. The hunter component generates candidates based on the passage retrieval for the original query, the gartherer component collects evidence for each candidate and score them b...

In a standard visual marking experiment, observers are presented with a display containing one set of elements (old elements) followed after a certain time interval by a second set of elements (new elements). The task of observers is to search for a target among the new elements. Typically, the time to find the target depends only on the number of new elements in the display and not on the numb...

Parallel communicating Watson-Crick automata systems were introduced in [2] as possible models of DNA computations. This combination of Watson-Crick automata and parallel communicating systems comes as a natural extension due to the new developments in DNA manipulation techniques. It is already known, see [5], that for Watson-Crick finite automata, the complementarity relation plays no active r...
