Complete Mitogenome Sequences Of Smooth Hammerhead Sharks, Sphyrna Zygaena, From The Eastern And Western Atlantic, Derek S. Guy, Cassandra L. Ruck, Jose V. Lopez, Mahmood S. Shivji

Biology Faculty Articles

We report the first mitogenome sequences of the circumglobally distributed, highly mobile, smooth hammerhead shark, Sphyrna zygaena, from the eastern and western Atlantic. Both genomes were 16,729 bp long with 13 protein-coding genes, two rRNAs, 22 tRNAs and a non-coding control region. The two Atlantic shark sequences differ from each other by 13 SNPs, and by 43 and 44 SNPs from the published mitogenome of an S. zygaena specimen from the eastern Pacific Ocean. The cross-Atlantic mitogenome sequences reported here provide a resource to assist with population genetics studies of this widely exploited species of conservation concern.

Infanticide In Chimpanzees: Taphonomic Case Studies From Gombe, Claire A. Kirchhoff, Michael L. Wison, Deus C. Mjungu, Jane Raphael, Shadrack Kamenya, D. Anthony Collins

Biological Sciences Faculty Research and Publications

Objectives

We present a study of skeletal damage to four chimpanzee (Pan troglodytes) infanticide victims from Gombe National Park, Tanzania. Skeletal analysis may provide insight into the adaptive significance of infanticide by examining whether nutritional benefits sufficiently explain infanticidal behavior. The nutritional hypothesis would be supported if bone survivorship rates and skeletal damage patterns are comparable to those of monkey prey. If not, other explanations, such as the resource competition hypothesis, should be considered.

Methods

Taphonomic assessment of two chimpanzee infants included description of breakage and surface modification, data on MNE, %MNE, and bone survivorship. Two additional infants …

Numerical And Experimental Study Of The Wetting Characteristics Of Water Droplets On Solid Substrates, Zichen Du, Damena Agonafer

Mechanical Engineering and Materials Science Independent Study

In this study, the author first reviewed the background and the mechanism of a highly efficient cooling method—i.e., the thin film evaporative cooling, in which the heat removal performance is highly dependent on the wetting characteristics of the working fluid. Then, the author studied the wetting behavior of water on different solid substrate both numerically and experimentally. By minimizing the free energy, Surface Evolver was used to explore the profile of the static liquid meniscus and the corresponding contact angle of water droplets on plain solid substrate and pillar substrate with sharp edge. Besides, goniometer experiments were performed to study …

The Total Harmonic Distortion (THD) is the most important feature that indicates the efficiency of the conversion process. In this research, due to the advantages of the cascade H-bridge inverter over other topologies, it has been used with the virtual stage PWM technique to investigate two different methods …

Feather Mite Abundance Varies But Symbiotic Nature Of Mite-Host Relationship Does Not Differ Between Two Ecologically Dissimilar Warblers, Alix E. Matthews, Jeffery L. Larkin, Douglas W. Raybuck, Morgan C. Slevin, Scott H. Stoleson, Than J. Boves

Biology Faculty Publications and Presentations

Feather mites are obligatory ectosymbionts of birds that primarily feed on the oily secretions from the uropygial gland. Feather mite abundance varies within and among host species and has various effects on host condition and fitness, but there is little consensus on factors that drive variation of this symbiotic system. We tested hypotheses regarding how within-species and among-species traits explain variation in both (1) mite abundance and (2) relationships between mite abundance and host body condition and components of host fitness (reproductive performance and apparent annual survival). We focused on two closely related (Parulidae), but ecologically distinct, species: Setophaga cerulea …

Doing Away With Battery Law, Anthony J. Sebok

Online Publications

Steve Sugarman is one of contemporary tort law’s leading figures, and one feature of his career which stands out is that he is willing to challenge modern orthodoxy. As the title of his classic 1985 article, Doing Away With Tort Law suggests, Sugarman is willing to recommend sweeping changes to private law. In Restating the Tort of Battery, Sugarman offers a proposal almost as radical as his 1985 proposal to get rid of tort law. Although he doesn’t say he wants to get rid of battery, once he is finished “restating” it, it is hard to see what is …

Midbrain Circuit Regulation Of Individual Alcohol Drinking Behaviors In Mice, Barbara Juarez, Carole Morel, Stacy M.

Croote, Yingbo Zhu, Song Zhang, Leandro F. Vendruscolo, Scott Edward, Amanda Roberts, Georgia E. Hodes, Yongke Lu, Erin S. Calipari, Dipesh Chaudhury, Allyson K. Friedman, Ming-Hu Han

Publications and Research

Alcohol-use disorder (AUD) is the most prevalent substance-use disorder worldwide. There is substantial individual variability in alcohol drinking behaviors in the population, the neural circuit mechanisms of which remain elusive. Utilizing in vivo electrophysiological techniques, we find that low alcohol drinking (LAD) mice have dramatically higher ventral tegmental area (VTA) dopamine neuron firing and burst activity. Unexpectedly, VTA dopamine neuron activity in high alcohol drinking (HAD) mice does not differ from alcohol naive mice. Optogenetically enhancing VTA dopamine neuron burst activity in HAD mice decreases alcohol drinking behaviors. Circuit-specific recordings reveal that spontaneous activity of nucleus accumbens-projecting VTA (VTA-NAc) neurons …

Stuck, Whitney Walters

Theses

Stuck is six-minutes and five seconds in duration. The film starts in an artist’s studio, a blob creature gingerly applies paint to a canvas. The goopy creature is exhausted and slumps onto their canvas. It rests its head there, but is startled by an alarm and remembers something. The blob panics and seizes its portfolio before rushing off.

The blob sits in an office while a bored man flips through the portfolio and hands back the book. Rejected, the blob melts and flows out the door into a hallway of parody movie posters and a display case of ‘mockquettes.’ The …

Histomorphology Of Trauma In Charred And Decomposed Remains, Mariya Bezugly

Student Theses

Decomposition and burning of human remains are frequently encountered in forensic cases, and pose a challenge at determining an accurate cause of death. At autopsy, macroscopic techniques fail to reach beyond superficial layers of degraded tissue to identify wound morphology that characterizes blunt-force gunshot, and sharp-force trauma. The postmortem damage imparted on tissue with pre-existing injuries, obstructs the external features of trauma. Exploring beyond charred and decayed superficial tissue, histo-morphological patterns of injury are still identifiable as shown in this thesis. With detailed observation to the pattern of tissue disruption- an understanding of the type of trauma imposed can be …

Makara Journal of Science

Alterations in the use of land for oil palm plantations can change the domination and activity of soil bacteria. More specifically, alteration in soil microbial communities can directly affect soil ecosystem functioning, particularly with respect to carbon and nitrogen cycles. Nitrogen can be a limiting nutrient, and the availability of nitrogen in the soil environment becomes a major factor in controlling the production of biomass. This research project aimed at studying the abundance of nitrogen-fixing, nitrogen-oxidizing, nitrogen-reducing, and ammonifying bacteria based on their functional genes in the tropical rain forests of Taman Nasional Bukit Duabelas (TNBD) and the oil palm …

Student Success Behaviors And Gender: Exploring The Impact On First-Year Students, Sarah Ramage

Graduate Theses, Dissertations, and Capstones

College demographics are rapidly evolving, and one area of concern is the enrollment and retention rates of male students. The National Center for Educational Statistics reported that in 2010, 57 percent of undergraduate students were female (Weaver-Hightower, 2010). The same report stated that the percentage was projected to grow to 59 percent by 2018 (Weaver-Hightower, 2010). Between 1997 and 2007, female enrollment has risen dramatically faster than male enrollment, with a 29 percent jump in 10 years. Male enrollment increased by 22 percent in the same time (Weaver-Hightower, 2010). Over time, this growing gender imbalance in higher education has been …

Snail Determines The Therapeutic Response To Mtor Kinase Inhibitors By Transcriptional Repression Of 4e-Bp1, Jun Wang, Qing Ye, Yanan Cao, Yubin Guo, Xiuping Huang, Wenting Mi, Side Liu, Chi Wang, Hsin-Sheng Yang, Binhua P. Zhou, B. Mark Evers, Qing-Bai She

Markey Cancer Center Faculty Publications

Loss of 4E-BP1 expression has been linked to cancer progression and resistance to mTOR inhibitors, but the mechanism underlying 4E-BP1 downregulation in tumors remains unclear. Here we identify Snail as a strong transcriptional repressor of 4E-BP1. We find that 4E-BP1 expression inversely correlates with Snail level in cancer cell lines and clinical specimens. Snail binds to three E-boxes present in the human 4E-BP1 promoter to repress transcription of 4E-BP1. Ectopic expression of Snail in cancer cell lines lacking Snail profoundly represses 4E-BP1 expression, promotes cap-dependent translation in polysomes, and reduces the anti-proliferative effect of mTOR kinase inhibitors. Conversely, genetic …

Pulsar J1411+2551: A Low-Mass Double Neutron Star System, J. G. Martinez, K. Stovall, P. C.C. Freire, J. S. Deneva, T. M. Tauris, A. Ridolfi, N. Wex, Fredrick Jenet, M. A. Mclaughlin, M. Bagchi

Physics & Astronomy Faculty Publications

In this work, we report the discovery and characterization of PSR J1411+2551, a new binary pulsar discovered in the Arecibo 327 MHz Drift Pulsar Survey. Our timing observations of the radio pulsar in the system span a period of about 2.5 years. This timing campaign allowed a precise measurement of its spin period (62.4 ms) and its derivative (9.6 ±0.7) ×10 -20 s s -1 ; from these, we derive a characteristic age of >9.1 Gyr and a surface magnetic field strength of < 2.6 ×10 9 G. These numbers indicate that this pulsar was mildly recycled by accretion of matter from the progenitor of the companion star. The system has an eccentric (e =0.17) 2.61 day orbit. This eccentricity allows a highly significant measurement of the rate of advance of periastron, . Assuming general relativity accurately describes the orbital motion, this implies a total system mass M =2.538 ±0.022 M o . The minimum companion mass is 0.92 M o and the maximum pulsar mass is 1.62 M o . The large companion mass and the orbital eccentricity suggest that PSR J1411+2551 is a double neutron star system; the lightest known to date including the DNS merger GW170817. Furthermore, the relatively low orbital eccentricity and small proper motion limits suggest that the second supernova had a relatively small associated kick; this and the low system mass suggest that it was an ultra-stripped supernova.

Managing Cattle Market Risk With Lrp Insurance, Jay Parsons

Cornhusker Economics

Price and market uncertainties pose a significant risk to cattle producers with a substantial amount of money invested in breeding livestock, land, and other infrastructure. Price protection through the Chicago Mercantile Exchange (CME) futures contracts and options can be used to help mitigate this risk but, in the case of futures contracts, they can also introduce financial burdens in the form of margin calls. Furthermore, many medium to small-scale producers prefer not to get involved with trading futures and options contracts.
