© 2019 Geological Society of America. A giant mass-transport complex was recently discovered in the eastern Arabian Sea, exceeding in volume all but one other known complex on passive margins worldwide. The complex, named the Nataraja Slide, was drilled by International Ocean Discovery Program (IODP) Expedition 355 in two locations where it is ~300 m (Site U1456) and ~200 m thick (Site U1457). The top of this mass-transport complex is defined by the presence of both reworked microfossil assemblages and deformation structures, such as folding and faulting. The deposit consists of two main phases of mass wasting, each consisting of …

Active Deformation And Plio-Pleistocene Fluvial Reorganization Of The Western Kura Fold-Thrust Belt, Georgia: Implications For The Evolution Of The Greater Caucasus Mountains, Lasha Sukhishvili, Adam M. Forte, Giorgi Merebashvili, Joel Leonard, Kelin X. Whipple, Zurab Javakhishvili, Arjun Heimsath, Tea Godoladze

Faculty Publications

© The Author(s), 2020. Published by Cambridge University Press. Since Plio-Pleistocene time, southward migration of shortening in the eastern part of the Greater Caucasus into the Kura foreland basin has progressively formed the Kura fold-thrust belt and Alazani piggyback basin, which separates the Kura fold-thrust belt from the Greater Caucasus. Previous work argued for an eastward propagation of the Kura fold-thrust belt, but this hypothesis was based on coarse geological maps and speculative ages for units within the Kura fold-thrust belt. Here we investigate the initiation of deformation within the Gombori range in the western Kura fold-thrust belt and evaluate …

Female Reproductive State Is Associated With Changes In Distinct Arginine Vasotocin Cell Types In The Preoptic Area Of Astatotilapia Burtoni, Julie M. Butler, Chase M. Anselmo, Karen P. Maruska

Faculty Publications

© 2020 Wiley Periodicals LLC Nonapeptides play a crucial role in mediating reproduction, aggression, and parental care across taxa. In fishes, arginine vasotocin (AVT) expression is related to social and/or reproductive status in most male fishes studied to date, and is linked to territorial defense, paternal care, and courtship. Despite a plethora of studies examining AVT in male fishes, relatively little is known about how AVT expression varies with female reproductive state or its role in female social behaviors. We used multiple methods for examining the AVT system in female African cichlid fish Astatotilapia burtoni, including immunohistochemistry for AVT, in …

The Avr4 Effector Is Involved In Cercosporin Biosynthesis And Likely Affects The Virulence Of Cercospora Cf. Flagellaris On Soybean, Josielle Santos Rezende, Marija Zivanovic, Maria Izabel Costa De Novaes, Zhi Yuan Chen

Faculty Publications

One of the most devastating fungal diseases of soybean in the southern USA is Cercospora leaf blight (CLB), which is caused mainly by Cercospora cf. flagellaris. Recent studies found that the fungal effector AVR4, originally identified in Cladosporium fulvum as a chitin-binding protein, is highly conserved among other Cercospora species. We wanted to determine whether it is present in C. cf. flagellaris and, if so, whether it plays a role in the pathogen infection of soybean. We cloned the Avr4 gene and created C. cf. flagellaris ∆avr4 mutants, which produced little cercosporin and significantly reduced expression of cercosporin biosynthesis genes. …

Assessing Salvinia Molesta Impact On Environmental Conditions In An Urban Lake: Case Study Of Lago Las Curias, Puerto Rico, Charles F. Wahl, Rodrigo Diaz, Jorge Ortiz-Zayas

Faculty Publications

Giant salvinia (Salvinia molesta Mitchell, Salviniaceae) is a free-floating fern native to Brazil that alters natural processes in aquatic ecosystems, causing ecological problems for water resource managers. Due to its ease of dispersal through fragmentation and rapid growth, giant salvinia can quickly become problematic, requiring persistent management efforts. If left unmanaged, giant salvinia creates a thick mat of vegetation, which limits sunlight penetration, reducing aquatic macrophytes, lowering dissolved oxygen and stressing aquatic organisms. Giant salvinia was first reported in Lago Las Curias, Cupey, San Juan, Puerto Rico, USA, in 2016 and covered the entire 19 ha waterbody in 2018. In …

Diverging Landscape Impacts On Macronutrient Status Despite Overlapping Diets In Managed (Apis Mellifera) And Native (Melissodes Desponsa) Bees, Christina L. Mogren, Mariá Soledad Benítez, Kevin Mccarter, Frédéric Boyer, Jonathan G. Lundgren

Faculty Publications

Declining pollinator populations worldwide are attributed to multiple stressors, including the loss of quality forage. Habitat management in agricultural areas often targets honey bees (Apis mellifera L.) specifically, with the assumption that native bees will benefit from an 'umbrella species' strategy. We tested this theory using a conservation physiology approach to compare the effects of landscape composition and floral dietary composition on the physiological status of honey bees and Melissodes desponsa in eastern South Dakota, USA. The total glycogen, lipid and protein concentrations were quantified from field collected bees. Next-generation sequencing of the trnL chloroplast gene from bee guts was …

Early Detection Of Parkinson's Disease Using Deep Learning And Machine Learning, Wu Wang, Junho Lee, Fouzi Harrou, Ying Sun

Faculty Publications

Accurately detecting Parkinson's disease (PD) at an early stage is certainly indispensable for slowing down its progress and providing patients the possibility of accessing to disease-modifying therapy. Towards this end, the premotor stage in PD should be carefully monitored. An innovative deep-learning technique is introduced to early uncover whether an individual is affected with PD or not based on premotor features. Specifically, to uncover PD at an early stage, several indicators have been considered in this study, including Rapid Eye Movement and olfactory loss, Cerebrospinal fluid data, and dopaminergic imaging markers. A comparison between the proposed deep learning model and …

Faculty Publications

© 2019 American Ornithological Society 2019. Published by Oxford University Press for the American Ornithological Society. The typical owl family (Strigidae) comprises 194 species in 28 genera, 14 of which are monotypic. Relationships within and among genera in the typical owls have been challenging to discern because mitochondrial data have produced equivocal results and because many monotypic genera have been omitted from previous molecular analyses. Here, we collected and analyzed DNA sequences of ultraconserved elements (UCEs) from 43 species of typical owls to produce concatenated and multispecies coalescent-based phylogenetic hypotheses for all but one genus in the typical owl family. …

Faculty Publications

© 2020. Published by The Company of Biologists Ltd Hypoxia is a pervasive stressor in aquatic environments, and both phenotypic plasticity and evolutionary adaptation could shape the ability to cope with hypoxia. We investigated evolved variation in hypoxia tolerance and the hypoxia acclimation response across fundulid killifishes that naturally experience different patterns of hypoxia exposure. We compared resting O2 consumption rate (M O2), and various indices of hypoxia tolerance [critical O2 tension (Pcrit), regulation index (RI), O2 tension (PO2) at loss of equilibrium (PLOE) and time to LOE (tLOE) at 0.6 kPa O2] in Fundulus confluentus, Fundulus diaphanus, Fundulus heteroclitus, …

A Higher-Dimensional Bourgain-Dyatlov Fractal Uncertainty Principle, Rui Han, Wilhelm Schlag

Faculty Publications

We establish a version of the fractal uncertainty principle, obtained by Bourgain and Dyatlov in 2016, in higher dimensions. The Fourier support is limited to sets Y ⊂ Rd which can be covered by finitely many products of δ-regular sets in one dimension, but relative to arbitrary axes. Our results remain true if Y is distorted by diffeomorphisms. Our method combines the original approach by Bourgain and Dyatlov, in the more quantitative 2017 rendition by Jin and Zhang, with Cartan set techniques.

Additive Schwarz Preconditioners For A Localized Orthogonal Decomposition Method, Susanne C. Brenner, José C. Garay, Li Yeng Sung

Faculty Publications

We investigate a variant of the localized orthogonal decomposition method (Henning and Peterseim, [Multiscale Model. Simul., 11 (2013), pp. 1149 1175] and Malqvist and Peterseim, [Math. Comp., 83 (2014), pp. 2583 2603]) for elliptic problems with rough coefficients. The construction of the basis of the multiscale finite element space is based on domain decomposition techniques, which is motivated by the recent work of Kornhuber, Peterseim, and Yserentant [Math. Comp., 87 (2018), pp. 2765 2774]. We also design and analyze additive Schwarz domain decomposition preconditioners for the resulting discrete problems.

Stabilization For A Chain Of Saturating Integrators Arising In The Visual Landing Of Aircraft With Sampling, Laurent Burlion, Michael Malisoff, Frédéric Mazenc

Faculty Publications

We provide a new output feedback control design for a chain of saturating integrators with imprecise output measurements where the outputs can also contain delays and sampling. Using a backstepping approach that leads to pointwise delays in the control and a dynamic extension, we prove input-to-state stability using a new dynamic extension approach. We utilize our main result to solve a problem in the visual landing of aircraft in the glide phase in the presence of delayed and sampled image processing.

The Influence Of Language Background And Second Language Phonetics Training On The Perception Of Lexical Stress In A Second Language, Todd A. Gibson, Carolina Bernales

Faculty Publications

Language background and second language (L2) training both have been found to contribute to L2 lexical stress perception. To explore their relative contributions, a lexical stress perception task was administered to a total of 129 university students of different language backgrounds. A group of 62 monolingual English-speaking students in the U.S.A. and 67 English-as-a-foreign-language students in Chile were asked to identify lexical stress in trochees and iambs. Chileans with previous phonetics training performed better than Chileans without the training and performed as well as their U.S. peers. U.S. participants and those Chileans without previous phonetics training performed better with trochees …

Rates And Predictors Of Co-Occurring Autism Spectrum Disorder In Boys With Fragile X Syndrome, Eileen Haebig, Audra Sterling, Andrea Barton-Hulsey, Laura Friedman

Faculty Publications

Background and aims: Males with fragile X syndrome display many behavioral features of autism spectrum disorder. Despite this overlap, our understanding of autism spectrum disorder symptoms and severity in fragile X syndrome is limited due to variation in assessment methods in the literature. Furthermore, the relationship between autism spectrum disorder symptoms and child characteristics, like age, language, and cognitive abilities, are not well understood in individuals with fragile X syndrome. Therefore, the first research aim was to compare the rates of autism spectrum disorder classifications from three commonly reported autism spectrum disorder assessments in the literature. Our second research aim …

Expressive Language Abilities Of Boys With Idiopathic Autism Spectrum Disorder And Boys With Fragile X Syndrome + Autism Spectrum Disorder: Cross-Context Comparisons, Elizabeth Hilvert, Audra Sterling, Eileen Haebig, Laura Friedman

Faculty Publications

Background and aims: Understanding the unique expressive language profiles of children with phenotypically similar, but distinct neurodevelopmental disorders, such as idiopathic autism spectrum disorder and fragile X syndrome with a co-diagnosis of autism spectrum disorder (fragile X syndrome + autism spectrum disorder), has both clinical and theoretical implications. However, comparative studies of these two clinical groups have been limited, and results have been inconsistent, partially as a result of different assessment methods being utilized. Thus, the current study compared the expressive language profiles of boys with idiopathic autism spectrum disorder and boys with fragile X syndrome + autism spectrum disorder …

Side Information Dependence As A Regularizer For Analyzing Human Brain Conditions Across Cognitive Experiments, Shuo Zhou, Wenwen Li, Christopher R. Cox, Haiping Lu

Faculty Publications

The increasing of public neuroimaging datasets opens a door to analyzing homogeneous human brain conditions across datasets by transfer learning (TL). However, neuroimaging data are high-dimensional, noisy, and with small sample sizes. It is challenging to learn a robust model for data across different cognitive experiments and subjects. A recent TL approach minimizes domain dependence to learn common cross-domain features, via the Hilbert-Schmidt Independence Criterion (HSIC). Inspired by this approach and the multi-source TL theory, we propose a Side Information Dependence Regularization (SIDeR) learning framework for TL in brain condition decoding. Specifically, SIDeR simultaneously minimizes the empirical risk and the …

Are Individual Differences In Auditory Processing Related To Auditory Distraction By Irrelevant Sound? A Replication Study, Emily M. Elliott, John E. Marsh, Jenna Zeringue, Corey I. Mcgill

Faculty Publications

Irrelevant sounds can be very distracting, especially when trying to recall information according to its serial order. The irrelevant sound effect (ISE) has been studied in the literature for more than 40 years, yet many questions remain. One goal that has received little attention involves the discernment of a predictive factor, or individual difference characteristic, that would help to determine the size of the ISE. The current experiments were designed to replicate and extend prior work by Macken, Phelps, and Jones (Psychonomic Bulletin & Review, 16, 139–144, 2009), who demonstrated a significant predictive relationship between the size of the ISE …
