Distribution Of Aromatase In The Brain Of The African Cichlid Fish Astatotilapia Burtoni: Aromatase Expression, But Not Estrogen Receptors, Varies With Female Reproductive-State, Karen P. Maruska, Julie M. Butler, Chase Anselmo, Ganga Tandukar Oct 2020

Distribution Of Aromatase In The Brain Of The African Cichlid Fish Astatotilapia Burtoni: Aromatase Expression, But Not Estrogen Receptors, Varies With Female Reproductive-State, Karen P. Maruska, Julie M. Butler, Chase Anselmo, Ganga Tandukar

Faculty Publications

© 2020 Wiley Periodicals, Inc. Estrogen synthesis and signaling in the brains of vertebrates has pleotropic effects ranging from neurogenesis to modulation of behaviors. The majority of studies on brain-derived estrogens focus on males, but estrogenic signaling in females likely plays important roles in regulation of reproductive cycling and social behaviors. We used females of the mouth brooding African cichlid fish, Astatotilapia burtoni, to test for reproductive state-dependent changes in estrogenic signaling capacity within microdissected brain nuclei that are important for social behaviors. Expression levels of the rate-limiting enzyme aromatase, but not estrogen receptors, measured by qPCR changes across the …

Neural Activation Patterns Associated With Maternal Mouthbrooding And Energetic State In An African Cichlid Fish, Karen P. Maruska, Julie M. Butler, Karen E. Field, Christopher Forester, Ashley Augustus Oct 2020

Neural Activation Patterns Associated With Maternal Mouthbrooding And Energetic State In An African Cichlid Fish, Karen P. Maruska, Julie M. Butler, Karen E. Field, Christopher Forester, Ashley Augustus

Faculty Publications

© 2020 IBRO Parental care is widespread in the animal kingdom, but for many species, provisioning energetic resources must be balanced with trade-offs between self-promoting and offspring-promoting behaviors. However, little is known about the neural mechanisms underlying these motivational decisions. Mouthbrooding is an extreme form of parental care most common in fishes that provides an ideal opportunity to examine which brain regions are involved in parenting and energetics. The African cichlid fish Astatotilapia burtoni is a maternal mouthbrooder in which females hold developing young inside their mouths for 2 weeks. This brood care makes feeding impossible, so females undergo obligatory …

Analytical And Experimental Study Of Fatigue-Crack-Growth Ae Signals In Thin Sheet Metals, Roshan Joseph, Victor Giurgiutiu Oct 2020

Analytical And Experimental Study Of Fatigue-Crack-Growth Ae Signals In Thin Sheet Metals, Roshan Joseph, Victor Giurgiutiu

Faculty Publications

The acoustic emission (AE) method is a very popular and well-developed method for passive structural health monitoring of metallic and composite structures. AE method has been efficiently used for damage source detection and damage characterization in a large variety of structures over the years, such as thin sheet metals. Piezoelectric wafer active sensors (PWASs) are lightweight and inexpensive transducers, which recently drew the attention of the AE research community for AE sensing. The focus of this paper is on understanding the fatigue crack growth AE signals in thin sheet metals recorded using PWAS sensors on the basis of the Lamb …

A Review Of Integrative Imputation For Multi-Omics Datasets, Meng Song, Jonathan Greenbaum, Joseph Luttrell, Weihua Zhou, Chong Wu, Hui Shen, Ping Gong, Chaoyang Zhang, Hong Wen Deng Oct 2020

A Review Of Integrative Imputation For Multi-Omics Datasets, Meng Song, Jonathan Greenbaum, Joseph Luttrell, Weihua Zhou, Chong Wu, Hui Shen, Ping Gong, Chaoyang Zhang, Hong Wen Deng

Faculty Publications

Multi-omics studies, which explore the interactions between multiple types of biological factors, have significant advantages over single-omics analysis for their ability to provide a more holistic view of biological processes, uncover the causal and functional mechanisms for complex diseases, and facilitate new discoveries in precision medicine. However, omics datasets often contain missing values, and in multi-omics study designs it is common for individuals to be represented for some omics layers but not all. Since most statistical analyses cannot be applied directly to the incomplete datasets, imputation is typically performed to infer the missing values. Integrative imputation techniques which make use …

Pinning The Conformation Of A Protein (Cora) In A Solute Matrix With Selective Binding, Warin Rangubpit, Sunan Kitjaruwankul, Pornthep Sompornpisut, R. B. Pandey Oct 2020

Pinning The Conformation Of A Protein (Cora) In A Solute Matrix With Selective Binding, Warin Rangubpit, Sunan Kitjaruwankul, Pornthep Sompornpisut, R. B. Pandey

Faculty Publications

Conformation of a protein (CorA) is examined in a matrix with mobile solute constituents as a function of solute–residue interaction strength (f) by a coarse-grained model with a Monte Carlo simulation. Solute particles are found to reach their targeted residue due to their unique interactions with the residues. Degree of slowing down of the protein depends on the interaction strength f. Unlike a predictable dependence of the radius of gyration of the same protein on interaction in an effective medium, it does not show a systematic dependence on interaction due to pinning caused by the solute binding. …

High-Temperature Resistant Water-Soluble Polymers Derived From Exotic Amino Acids, Sumant Dwivedi, Aniruddha Nag, Shigeki Sakamoto, Yasuyoshi Funahashi, Toyohiro Harimoto, Kenji Takada, Tatsuo Kaneko

Faculty Publications

© The Royal Society of Chemistry. High-performance water-soluble polymers have a wide range of applications from engineering materials to biomedical plastics. However, existing materials are either natural polymers that lack high thermostability or rigid synthetic polymers. Therefore, we design an amino acid-derived building block, 4,4′-diamino-α-truxillate dianion (4ATA2−), that induces water solubility in high-performance polymers. Polyimides containing 4ATA2− units are intrinsically water-soluble and are processed into films cast from an aqueous solution. The resulting polyimide films exhibit exceptional transparency and extremely high thermal stability. In addition, the films can be made insoluble in water by simple post-treatment using …

Language Matters: Examining The Language-Related Needs And Wants Of Writers In A First-Year University Writing Course, Grant Eckstein, Dana Ferris

Faculty Publications

All writing involves complex linguistic knowledge and thoughtful decision-making. But where do students acquire the linguistic tools needed to write effectively? Many students come from diverse backgrounds and may need additional support and/or instruction in language and grammar. In order to better understand this situation, we conducted a qualitative multiple-case study to examine the experiences of 12 students in a first-year university-level composition course to understand the extent of their diverse learning backgrounds and language needs and expectations. We synthesized information from surveys, interviews, and written texts into narratives about each student’s attitudes toward language and writing and also examined …

The Hellan-Herrmann-Johnson Method With Curved Elements, Douglas N. Arnold, Shawn W. Walker Oct 2020

The Hellan-Herrmann-Johnson Method With Curved Elements, Douglas N. Arnold, Shawn W. Walker

Faculty Publications

We study the finite element approximation of the Kirchhoff plate equation on domains with curved boundaries using the Hellan-Herrmann-Johnson (HHJ) method. We prove optimal convergence on domains with piecewise Ck+1 boundary for k ≥ 1 when using a parametric (curved) HHJ space. Computational results are given that demonstrate optimal convergence and how convergence degrades when curved triangles of insufficient polynomial degree are used. Moreover, we show that the lowest order HHJ method on a polygonal approximation of the disk does not succumb to the classic Babuška paradox, highlighting the geometrically nonconforming aspect of the HHJ method.

Dynamics Of Pdms- G-Pdms Bottlebrush Polymers By Broadband Dielectric Spectroscopy, Bruno Jakobi, Karin J. Bichler, Anna Sokolova, Gerald J. Schneider Oct 2020

Dynamics Of Pdms- G-Pdms Bottlebrush Polymers By Broadband Dielectric Spectroscopy, Bruno Jakobi, Karin J. Bichler, Anna Sokolova, Gerald J. Schneider

Faculty Publications

Copyright © 2020 American Chemical Society. Poly(dimethylsiloxane) (PDMS)-based bottlebrush polymers, PDMS-g-PDMS, have been synthesized by anionic polymerization in combination with a condensation-based grafting reaction. Bottlebrush polymers show intriguing features, e.g., extremely low viscosities. Hereby, studies of their dynamics are rare. Therefore, we focus on the segmental relaxation by broadband dielectric spectroscopy. An increasing cross-sectional radius proportional to the increasing side chain length has been observed by small-angle neutron scattering over three samples. A comparison of the segmental relaxation times of the bottlebrushes with the respective linear chains reveals slower dynamics in the former. For longer chains, this effect vanishes.

Ugandan Adolescents’ Gender Stereotype Knowledge About Jobs, Flora Farago, Natalie D. Eggum-Wilkens, Linlin Zhang Oct 2020

Ugandan Adolescents’ Gender Stereotype Knowledge About Jobs, Flora Farago, Natalie D. Eggum-Wilkens, Linlin Zhang

Faculty Publications

Ugandan adolescents ages 11- to 17-years-old (N = 201; 48% girls; M age = 14.62) answered closed- and open-ended questions about occupational gender segregation, allowing researchers to assess their gender stereotype knowledge. Adolescents answered 38 closed-ended questions such as ‘who is more likely to be a doctor?’ and were asked to list masculine, feminine, and gender-neutral jobs. Data were analyzed via descriptive statistics, chi-square tests, t-tests, and thematic coding. Findings indicated that adolescents were fairly egalitarian about jobs and there were no differences in occupational stereotype knowledge between males and females. Findings present reasons for hope and for continued …

Background: The structure of the Hoyle state, a highly α-clustered state at 7.65 MeV in C12, has long been the subject of debate. Understanding if the system comprises of three weakly interacting α particles in the 0s orbital, known as an α-condensate state, is possible by studying the decay branches of the Hoyle state. Purpose: The direct decay of the Hoyle state into three α particles, rather than through the Be8 ground state, can be identified by studying the energy partition of the three α particles arising from the decay. This paper provides details on the breakup mechanism of the …

Tunable Dual Plasmon-Induced Transparency Based On A Monolayer Graphene Metamaterial And Its Terahertz Sensing Performance, Jiahao Ge, Chenglong You, He Feng, Xiaoman Li, Mei Wang, Lifeng Dong, Georgios Veronis, Maojin Yun Oct 2020

Tunable Dual Plasmon-Induced Transparency Based On A Monolayer Graphene Metamaterial And Its Terahertz Sensing Performance, Jiahao Ge, Chenglong You, He Feng, Xiaoman Li, Mei Wang, Lifeng Dong, Georgios Veronis, Maojin Yun

Faculty Publications

In this paper, tunable dual plasmon-induced transparency (PIT) is achieved by using a monolayer graphene metamaterial in the terahertz region, which consists of two graphene strips of different sizes and a graphene ring. As the dual PIT effect is induced by the destructive interference between the two quasi-dark modes and the bright mode, we propose a four-level plasmonic system based on the linearly coupled Lorentzian oscillators to explain the mechanism behind the dual PIT. It is proved that the theoretical results agree well with the simulation results. Most importantly, the sensing properties of the designed device have been investigated in …

The Goodness Of God And His Children As A Fundamental Theological Concept In The Book Of Mormon, Noel B. Reynolds Oct 2020

The Goodness Of God And His Children As A Fundamental Theological Concept In The Book Of Mormon, Noel B. Reynolds

Faculty Publications

The phrase goodness of God does occur occasionally in the Hebrew Bible, but has not been considered by Old Testament scholars. to be a key piece of Israelite theology. Rather, it has been interpreted as just another way of talking about God’s acts of hesed or loving kindness for his covenant people and is usually interpreted in the context of the covenants Israel received through Abraham and Moses. The Book of Mormon, on the other hand, presents an explicit divine plan that existed before Abraham—even before the creation of the earth—which had as its purpose making eternal life possible for …

We present geometric and dynamical modeling of the broad line region (BLR) for the multi-wavelength reverberation mapping campaign focused on NGC 5548 in 2014. The data set includes photometric and spectroscopic monitoring in the optical and ultraviolet, covering the Hβ, C iv, and Ly broad emission lines. We find an extended disk-like Hβ BLR with a mixture of near-circular and outflowing gas trajectories, while the C iv and Ly BLRs are much less extended and resemble shell-like structures. There is clear radial structure in the BLR, with C iv and Ly emission arising at smaller radii than the Hβ emission. …

Transportation infrastructure such as highways and bridges requires upgrades and maintenance. In many U.S. regions, these requirements have surpassed current funding, so new solutions are needed. One obvious though imperfect source is gasoline taxes, but raising these is politically risky, regardless of need. To illuminate this conflict, we analyze data from four random-sample telephone surveys (2016–2018, n = 2,035) that asked residents in the U.S. state of New Hampshire about their perceptions of highway and bridge conditions, and support for gas tax increases. About one third of the respondents counterfactually reported that highway and bridge conditions had improved compared with …

We introduce a new framework for studying clustering and for calculating α partial widths using ab initio wave functions. We demonstrate the formalism for Ne20, by calculating the overlap between the O16+α cluster configuration and states in Ne20 computed in the abinitio symmetry-adapted no-core shell model. We present spectroscopic amplitudes and spectroscopic factors, and compare those to no-core symplectic shell-model results in larger model spaces, to gain insight into the underlying physics that drives α clustering. Specifically, we report on the α partial width of the lowest 1- resonance in Ne20, which is found to be in good agreement with …

In powder bed fusion additive manufacturing (AM), the fusing process is temperature and time dependent. However, little work has been done to understand how different processing temperatures and times might impact the mechanical properties at longer sintering times than are typical in laser sintering (LS) systems. Prior results with projection sintering have shown that heating for longer times (>1s) improves part toughness compared to laser sintering. In this work, Large Area Projection Sintering (LAPS) is used to sinter entire layers of material simultaneously over the course of a few seconds with spatial control of layer temperature.

Shelf-stable, ready-to-eat shrimp offer a convenient, portion-controlled option for a highly desirable seafood commodity. The perishability of shrimp requires tight cold-temperature control during distribution and handling. Thermal processing of shrimp was evaluated in a multimode retort with automated control of come-up, heat, and cool times and with addition of high-speed reciprocal agitation. Reciprocal agitation was compared with static retort for thermal process and quality parameters, including cook time, process time to achieve target lethality (F0), cook yield, texture, and appearance of shelf-stable shrimp. Total retort thermal processing times decreased from 30 min at 0 shakes per minute (SPM) to 17.1 …

In marine operations underwater manipulators play a primordial role. However, due to uncertainties in the dynamic model and disturbances caused by the environment, low-level control methods require great capabilities to adapt to change. Furthermore, under position and torque constraints the requirements for the control system are greatly increased. Reinforcement learning is a data driven control technique that can learn complex control policies without the need of a model. The learning capabilities of these type of agents allow for great adaptability to changes in the operative conditions. In this article we present a novel reinforcement learning low-level controller for the position …
