Using Deep Features To Predict Where People Look, Matthias Kümmerer, Matthias Bethge

MODVIS Workshop

When free-viewing scenes, the first few fixations of human observers are driven in part by bottom-up attention. We seek to characterize this process by extracting all information from images that can be used to predict fixation densities (Kuemmerer et al, PNAS, 2015). If we ignore time and observer identity, the average amount of information is slightly larger than 2 bits per image for the MIT 1003 dataset. The minimum amount of information is 0.3 bits and the maximum 5.2 bits. Before the rise of deep neural networks the best models were able to capture 1/3 of this information on average. …

Modelling Short-Latency Disparity-Vergence Eye Movements Under Dichoptic Unbalanced Stimulation, Agostino Gibaldi, Guido Maiello, Peter J. Bex, Silvio P. Sabatini

MODVIS Workshop

Vergence eye movements align the optical axes of our two eyes onto an object of interest, thus facilitating the binocular summation of the images projected onto the left and the right retinae into a single percept. Both the computational substrate and the functional behaviour of binocular vergence eye movements have been the topic of in depth investigation. Here, we attempt to bring together what is known about computation and function of vergence mechanism. To this aim, we evaluated of a biologically inspired model of horizontal and vertical vergence control, based on a network of V1 simple and complex cells. The …

Learning Object Representations For Modeling Attention In Real World Scenes, Alex Schwarz, Frederik Beuth, Fred H. Hamker

MODVIS Workshop

Models of visual attention have been rarely used in real world tasks as they have been typically developed for psychophysical setups using simple stimuli. Thus, the question remains how objects must be represented to allow such models an operation in real world scenarios. We have previously presented an attention model capable of operating on real-world scenes (Beuth, F., and Hamker, F. H. 2015, NCNC, which is a successor of Hamker, F. H., 2005, Cerebral Cortex), and show here how its object representations have been learned. We have used a learning rule based on temporal continuity (Földiák, P., 1991, Neural Computation) …

Quantitative Mass Spectrometry Reveals Changes In Histone H2b Variants As Cells Undergo Inorganic Arsenic-Mediated Cellular Transformation, Matthew Rea, Tingting Jiang, Rebekah Eleazer, Meredith Eckstein, Alan G. Marshall, Yvonne N. Fondufe-Mittendorf

Molecular and Cellular Biochemistry Faculty Publications

Exposure to inorganic arsenic, a ubiquitous environmental toxic metalloid, leads to carcinogenesis. However, the mechanism is unknown. Several studies have shown that inorganic arsenic exposure alters specific gene expression patterns, possibly through alterations in chromatin structure. While most studies on understanding the mechanism of chromatin-mediated gene regulation have focused on histone post-translational modifications, the role of histone variants remains largely unknown. Incorporation of histone variants alters the functional properties of chromatin. To understand the global dynamics of chromatin structure and function in arsenic-mediated carcinogenesis, analysis of the histone variants incorporated into the nucleosome and their covalent modifications is required. Here …

A Pilot Study Analyzing Solvents In Electronic Cigarette “E-Liquid” Using High Performance Liquid Chromatography, Austin Matranga, Olivia Sellers, Matthew Gartner

Student Scholar Symposium Abstracts and Posters

Introduction: Electronic cigarettes, also known as an e-cigarette, are battery-powered devices that use a heating element to convert a liquid (“e-liquid”) into an inhalable aerosol. Their advertised use is as a nicotine delivery system minus the harmful chemicals. Since “e-liquids” and the electronic cigarettes are not regulated by the Food and Drug Administration, it is not well known under what conditions, if any, carcinogenic compounds are produced. There has been little research on the toxicity of electronic cigarettes. The aim of this study was to determine if formaldehyde or acetaldehyde are formed from the e-liquid by the high heat of …

Ocean Acidification And Predator-Prey Relations: Correlating Disruption Of Predator Avoidance With Chemosensory Deficits, Alexandra Fw Sidun, William G. Wright

Student Scholar Symposium Abstracts and Posters

One of the most destructive effects of global climate change is the increased carbon sequestering and consequential acidification of our world’s oceans. The impacts of ocean acidification on marine organisms are still relatively unknown, especially effects on behavioral ecology. Avoiding predation has emerged from recent behavioral ecology literature as a critical feature in the life history of a wide array of animal species; experiments on marine fishes suggest acidic water compromises their predator-avoidance abilities. Recent assays in our lab suggest predator-induced behavior is reduced by weakly acidic water. These experiments do not address the potential factor of generalized malaise caused …

Connecting The Physiological And Behavioral Response To Heat Stress On A Warming Planet, Anastasia Kalyta

Student Scholar Symposium Abstracts and Posters

Intertidal communities are considered good models of the biological effects of climate change on ecosystems, as their resident organisms are subjected to heat spells during daytime low tides. The increasing heat exposure can elicit behavioral as well as physiological responses in intertidal organisms. We studied the relationship between these responses to heat stress in the blue-banded hermit crab, Pagurus samuelis, by inducing a “heat shock” with elevated water temperature of 29 °C for 2.5 h. The behavioral effect of heat-shock was quantified using a 30-minute feeding assay, measuring the mass of a standard squid pellet consumed by individual hermit crabs. …

Destruction Of Opportunistic Pathogens Via Polymer Nanoparticle-Mediated Release Of Plant-Based Antimicrobial Payloads, Dahlia N. Amato, Douglas V. Amato, Olga V. Mavrodi, Dwaine A. Braasch, Susan E. Walley, Jessica R. Douglas, Dmitri V. Mavrodi, Derek L. Patton

Faculty Publications

The synthesis of antimicrobial thymol/carvacrol‐loaded polythioether nanoparticles (NPs) via a one‐pot, solvent‐free miniemulsion thiol‐ene photopolymerization process is reported. The active antimicrobial agents, thymol and carvacrol, are employed as “solvents” for the thiol‐ene monomer phase in the miniemulsion to enable facile high capacity loading (≈50% w/w), excellent encapsulation efficiencies (>95%), and elimination of all postpolymerization purification processes. The NPs serve as high capacity reservoirs for slow‐release and delivery of thymol/carvacrol‐combination payloads that exhibit inhibitory and bactericidal activity (>99.9% kill efficiency at 24 h) against gram‐positive and gram‐negative bacteria, including both saprophytic (Bacillus subtilis ATCC 6633 and Escherichia coli …

Background: Obesity affects nearly one in five children and is associated with increased risk of premature death. Obesity-related heart disease contributes to premature death. We aimed to use cardiovascular magnetic resonance (CMR) to comprehensively characterize the changes in cardiac geometry and function in obese children.

Methods and results: Forty-one obese/overweight (age 12 ± 3 years, 56 % female) and 29 healthy weight children (age 14 ± 3 years, 41 % female) underwent CMR, including both standard cine imaging and displacement encoded imaging, for a complete assessment of left ventricular (LV) structure and function. After adjusting for age, LV mass index …

Determining The Role Of Erbeta In The Activation Of Erk1/2 By The Environmental Estrogens, Cadmium Chloride And Sodium Arsenite, In Human Lung Adenocarcinoma Cells, Jeffrey Hyzer

Undergraduate Theses

Estrogen is involved in the proliferation of adenocarcinoma lung cells. However, the proliferative role of two endocrine disrupters, cadmium chloride and sodium arsenite, in lung adenocarcinoma is less clear. Previous studies have shown that these two heavy metals can induce cellular proliferation and activate phosphorylation of ERK1/2 in a human lug adenocarcinoma cell line, NCI-H1793. Induced phosphorylation of ERK1/2 by these compounds is decreased in the presence of an estrogen receptor antagonist, ICI-182,780, suggesting that cadmium and arsenite stimulate these responses, in part, via a non-genomic estrogen signaling pathway. There are three known estrogen receptors, but it is unclear which …

Discrete But Variable Structure Of Animal Societies Leads To The False Perception Of A Social Continuum, Dustin R. Rubenstein, Carlos A. Botero, Eileen A. Lacey

Biology Faculty Research

Animal societies are typically divided into those in which reproduction within a group is monopolized by a single female versus those in which it is shared among multiple females. It remains controversial, however, whether these two forms of social structure represent distinct evolutionary outcomes or endpoints along a continuum of reproductive options. To address this issue and to determine whether vertebrates and insects exhibit the same patterns of variation in social structure, we examined the demographic and reproductive structures of 293 species of wasps, ants, birds and mammals. Using phylogenetically informed comparative analyses, we found strong evidence indicating that not …

Mathematics Faculty Research

Alzheimer’s disease (AD) is characterized by two molecular pathologies: cerebral β-amyloidosis in the form of β-amyloid (Aβ) plaques and tauopathy in the form of neurofibrillary tangles, neuritic plaques, and neuropil threads. Until recently, only Aβ could be studied in humans using positron emission tomography (PET) imaging owing to a lack of tau PET imaging agents. Clinical pathological studies have linked tau pathology closely to the onset and progression of cognitive symptoms in patients with AD. We report PET imaging of tau and Aβ in a cohort of cognitively normal older adults and those with mild AD. Multivariate analyses identified unique …

Gluten-Free And Casein-Free Dietary Intervention For Children Diagnosed With Autism Spectrum Disorder, Avalon Derlacki

Student Scholar Symposium Abstracts and Posters

In the United States, autism spectrum disorders (ASD) had a prevalence of 1 in 150 children in 2000. In the year 2012, the prevalence of ASD in the United States jumped to 1 in 68 children (Centers of Disease Control and Prevention, 2012). Due to the increase in diagnoses of ASD, researchers have sought out different ways to help decrease maladaptive symptoms associated with ASD’s. Many parents of children diagnosed with ASD administer a gluten-free and casein-free (GFCF) diet to their children in hopes of reducing their maladaptive symptoms. The project hypothesis states that if a child under the age …

When Meaningful Writing Reflects Vincentian Values, Michele Eodice, Anne Ellen Geller, Neal Lerner

Journal of Vincentian Social Action

In The Meaningful Writing Project – our study of over 700 seniors at three universities – students describe how education values are embodied in writing projects in and out of school. In brief, our results show that students find meaning when they are invited to tap into the power of personal connection, see what they are writing as applicable and relevant to the real world, imagine their future selves, immerse themselves in what they are thinking and writing about, and experience research for learning. In many cases, the experiences students reported are aligned with Vincentian values for higher education, namely …
