Contrast Negation Differentiates Visual Pathways Underlying Dynamic And Invariant Facial Processing, Pamela M. Pallett, Ming Meng

Dartmouth Scholarship

Abstract Bruce and Young (1986) proposed a model for face processing that begins with structural encoding, followed by a split into two processing streams: one for the dynamic aspects of the face (e.g., facial expressions of emotion) and the other for the invariant aspects of the face (e.g., gender, identity). Yet how this is accomplished remains unclear. Here, we took a psychophysical approach using contrast negation to test the Bruce and Young model. Previous research suggests that contrast negation impairs processing of invariant features (e.g., gender) but not dynamic features (e.g., expression). In our first experiment, participants discriminated differences in …

Late Glacial And Holocene Record Of Climatic Change In The Southern Rocky Mountains From Sediments In San Luis Lake, Colorado, Usa, Fasong Yuan, Max R. Koran, Andrew Valdez

Biological, Geological, and Environmental Faculty Publications

Large rapid climate changes occurred over the last glacial cycle in the southwestern United States and elsewhere in many regions of the world. Some of these changes were attributed to alternations between stadial and interstadial conditions in the North Atlantic. But intense debate exists on how climate anomalies in the North Atlantic transmit to the southwest. Here we report a sediment record from San Luis Lake in southern Colorado, through analyses of grain size, magnetic susceptibility, Mg/Ca, total inorganic carbon, δ¹⁸O and δ¹³C, to indicate climatic and environmental changes in the southern Rocky Mountains over the …

These changes to the oceans can greatly affect many of the ecosystems that reside in them. One of the main ecosystems that are being affected by climate change …

Newspaper Presidential Endorsements: Who Publications Support, Why Votes Change, And The Practice’S Sharp Decline, Jesse Rifkin

Honors Scholar Theses

Do newspapers tend to mirror the political preferences of their primary readership? In other words, do they actually matter? Do they matter only if they mirror public opinion? What if they lead public opinion? Why do some newspaper endorsements change over time? Why are a growing number of newspapers discontinuing presidential endorsements – will they soon be a thing of the past? This paper aims to answer those questions and more.

A few trends stand out, three in particular.

1) The long history of newspapers endorsing presidential candidates may be coming to an end. In recent years many have discontinued …

Ba/Ca Ratios In Otoliths Of Southern Bluefin Tuna (Thunnus Maccoyii) As A Biological Tracer Of Upwelling In The Great Australian Bight, Yu-Ting Lin, Chia-Hui Wang, Chen-Feng You, Wann-Nian Tzeng

Journal of Marine Science and Technology–Taiwan

The southern bluefin tuna (Thunnus maccoyii) is a longlived, large, and highly migratory marine fish in the Indian Ocean. They can live up to 40 years and migrate to the Great Australian Bight in the summer when 1-4 years old. The Great Australian Bight is characterized as the most productive coastal upwelling zone in southern Australia and is the largest area of cool-water carbonate sedimentation in the world. The barium (Ba) level is poor in the open ocean but rich in the upwelling area. This study used otolith Ba/Ca ratios as a natural tag to confirm that southern bluefin tuna …

A Multi-Agent, Connectionist Model Of Metonymy Production, Robert J. Powers

Honors Scholar Theses

Metonymy, like metaphor, has received much attention in cognitive linguistics literature (Croft, 1993; Kövecses & Radden, 1998; Panther & Radden, 1999). Most experimental work focuses on comprehension. However, why a speaker would choose to produce a metonym in some cases and not others is not fully understood. Connectionist models are well-suited to deal with the partialsemantic/partial-syntactic information which is characteristic of metonymy. Moreover, thesemodels can capture some of the complex, time-varying dynamics of language development. Here, a model is presented in which dyads of artificial agents (each a recurrent neural network based on Rogers, et al., 2004) were trained in …

The Legacy Of 1940: The Election Of Franklin D. Roosevelt To A Third Term, Kyle Lindsay

History & Classics Undergraduate Theses

For my honors history thesis, I examined the decision of Franklin D. Roosevelt to run for a third presidential term in 1940. This decision was an important one, for no other President in American history had been elected to a third term. My research indicated that despite his personal wishes, Roosevelt believed that he had to run again in 1940 to guide the United States during the uncertain period leading up to World War II.

Automatic Location For Multi-Symbology And Multiple 1d And 2d Barcodes, Daw-Tung Lin, Chin-Lin Lin

Journal of Marine Science and Technology–Taiwan

Multi-symbology barcode location is a practical and challenging issue. Image-based barcode recognition techniques are robust and extendable approaches for reading versatile one-dimensional (1D) and two-dimensional (2D) barcodes. Most methods may work for a single 1D or 2D barcode or rely on a unique pattern to locate a single 1D or 2D barcode. This work proposes a general localization framework for extraction of real barcodes under complex backgrounds when multiple symbology types exist in the same snapshot for 1D barcodes, 2D barcodes, or both. There are five steps of the proposed algorithm: image grayscale conversion, adaptive thresholding, application of a modified …

Characteristics And Effects Of Muscular Dystrophy In Broiler Chickens, Kayla N. Smith

Honors Theses

Muscular dystrophy is very common among broilers, which are chickens raised specifically for meat production. When dystrophic chickens are mated, or when normal and dystrophic chickens are mated, it is very likely that at least fifty percent of the clutch will end up with muscular dystrophy since it is inherited as a co-dominant disorder (Fujiwara et al., 2009). For my study, eggs were obtained from a local farm, and allowed to hatch. Among these hatchings were chicks who exhibited some traits of muscular dystrophy. It is possible that the parents of the seemingly dystrophic chicks may carry the mutated WWP1 …

Materials Science and Engineering Faculty Publications and Presentations

A catalytic colorimetric detection scheme that incorporates a DNA-based hybridization chain reaction into gold nanoparticles was designed and tested. While direct aggregation forms an inter-particle linkagefrom only one target DNA strand, catalytic aggregation forms multiple linkages from a single target DNA strand. Gold nanoparticles were functionalized with thiol-modified DNA strands capable of undergoing hybridization chain reactions. The changes in their absorption spectra were measured at different times and target concentrations and compared against direct aggregation. Catalytic aggregation showed a multifold increase in sensitivity at low target concentrations when compared to direct aggregation. Gelelectrophoresis was performed to compare DNA hybridization reactions …

An Effective Color-Difference-Based Demosaicking Method, Yea-Shuan Huang, Sheng-Yi Cheng

Journal of Marine Science and Technology–Taiwan

This paper proposes an effective color-difference-based (ECDB) interpolation algorithm for color filter array (CFA) image demosaicking. A CFA image consists of a set of spectrally selective filters which are arranged in an interleaved pattern such that only one color component is sampled at each pixel location. To improve the quality of reconstructed fullcolor images from CFA images, the ECDB algorithm first analyzes the samples immediately around a missing green pixel to determine suitable samples for interpolating the value of this missing green pixel. After finishing the interpolation operations of all the missing green pixels, a complete green plane (i.e G …

Determining The Internal Structure Of Cement-Based Materials By Using Mri Techniques, Hsiang-Wei Chiang, Ran Huang, Chia-Jung Tsai

Journal of Marine Science and Technology–Taiwan

The primary concerns of the internal structure of cementbased materials involve the distribution of pores, pore size, and the manner in which they are connected. Thoroughly understanding the distributive rules of pores and the approaches to breaking their links can contribute considerably to enhancing the durability of cement-based materials. Several methods are used to measure the pores of cement-based materials; however, they cannot determine the exact location of pores or structural links. Magnetic resonance imaging (MRI) has been widely applied in physical examinations and has matured to the level of being able to obtain 3D images of the organs of …
