- Description:
- The relationship between words in a sentence often tell us more about the underlying semantic content of a document than its actual words, individually. Recent publications in the natural language processing arena, more specifically using word embeddings, try to incorporate semantic aspects into their word vector representation by considering the context of words and how they are distributed in a document collection. In this work, we propose two novel algorithms, called Flexible Lexical Chain II and Fixed Lexical Chain II that combine the semantic relations derived from lexical chains, prior knowledge from lexical databases, and the robustness of the distributional hypothesis in word embeddings into a single decoupled system. In short, our approach has three main contributions: (i) unsupervised techniques that fully integrate word embeddings and lexical chains; (ii) a more solid semantic representation that considers the latent relation between words in a document; and (iii) lightweight word embeddings models that can be extended to any natural language task. Knowledge-based systems that use natural language text can benefit from our approach to mitigate ambiguous semantic representations provided by traditional statistical approaches. The proposed techniques are tested against seven word embeddings algorithms using five different machine learning classifiers over six scenarios in the document classification task. Our results show that the integration between lexical chains and word embeddings representations sustain state-of-the-art results, even against more complex systems.

- Description:
- The aim of the research to study the temporal evolution of the Sub-Auroral Polarizations Streams (SAPS) with multiple instruments. Aurora images are important to identify the electrodynamics in the high latitude ionosphere. Data used in this research were collected and provided by Dr. Jun Liang at University of Calgary, and analyzed by Zihan Wang for the article accompanying this deposit. The data was collected from all sky imagers (ASI) located in Saskatoon, Canada. and saskrainbow01.sav contains the rgb channels from ASI. It can be opened using IDL. saskasiskymap.gm5 contains the sky map of the ASI. It shows the geographic location of the figure pixels. aurora_diff.pro is the procedure to recover the data from saskrainbow01.sav and make plots. draw_colorbar.pro is the procedure to add a colorbar to the plot. mlon_smp_towang.pro and rebinsmpkeo_towang.pro can together make keogram plots. Run mlon_smp_towang.pro first and then rebinsmpkeo_towang.pro.

- Description:
- Nighttime and diurnal surveys in the lowland Peruvian Amazon of Los Amigos Biological Station were conducted in order to describe herpetological diversity at this site. As a result of these surveys, the predation event between a Pamphobeteus sp. and Marmosops sp. and the myiasis of Ranitomeye uakarii were observed. The video footage was recorded in order to document these interesting interactions between arthropod predators and parasites and vertebrate prey and hosts, and are included for publication in the short communication "Ecological interactions between arthropods and small vertebrates in a lowland Amazon rainforest" in the journal Amphibian and Reptile Conservation.

- Description:
- Geological and geophysical observations reveal along-strike fault zone heterogeneity on major strike-slip faults, which can play a significant role in earthquake rupture propagation and termination. I present 2D dynamic rupture simulations to demonstrate rupture characteristics in such heterogeneous fault zone structure. The modeled rupture is nucleated in a damaged fault zone and propagates on a preexisting fault towards the zone of intact rocks. There is an intermediate range of nucleation lengths that only allow rupture to spontaneously propagate in the damaged fault zone but not in a homogeneous medium. I find that rupture with an intermediate nucleation length tends to stop when it reaches the zone of intact rocks, especially when the rupture propagation distance in the damaged fault zone is relatively short and when the damaged fault zone is relatively narrow or smooth in the fault-normal direction. Pronounced small-scale heterogeneity within the damaged fault zone also contributes to such early rupture termination. In asymmetric fault zones bisected by a bimaterial fault, rupture moving in the direction of slip of faster rocks tends to terminate under the same conditions as in symmetric fault zones, whereas rupture moving in the direction of slip of slower rocks can penetrate into the zone of intact rocks. Break-through rupture is allowed when a sufficiently-large asperity is located at the edge of the zone of intact rocks. The results suggest the along-strike fault zone heterogeneity can play a critical role in seismicity distribution. The data set contains multiple folders of simulation results from the SEM2DPACK that demonstrate the above findings. The folder name includes the model parameters in each simulation as explained in the README file. The Flt01_sem2d.data file in the folder documents the slip, slip rate and stresses from each simulation. The files are also explained in the manual of SEM2DPACK ( http://web.gps.caltech.edu/~ampuero/soft/users_guide_sem2dpack.pdf). Please refer to section 4.6 in the manual and use “sem2d_read_fault.m” in the POST folder of SEM2DPACK to plot the results.
