Faculty Publications

Peg3 (paternally expressed gene 3) is an imprinted gene encoding a DNA-binding protein. This gene plays important roles in controlling fetal growth rates and nurturing behaviors. In the current study, a new mutant mouse model has been generated to further characterize the functions of this DNA-binding protein. Besides known phenotypes, this new mutant model also revealed potential roles of Peg3 in mammalian reproduction. Female heterozygotes produce a much smaller number of mature oocytes than the wild-type littermates, resulting in reduced litter sizes. According to genome-wide expression analyses, several placenta-specific gene families are de-repressed in the brain of Peg3 heterozygous embryos, …

The extraction of detailed nuclear structure information from transfer reactions requires reliable, well-normalized data, as well as optical potentials and a theoretical framework demonstrated to work well in the relevant mass and beam energy ranges. It is rare that the theoretical ingredients can be tested well for exotic nuclei owing to the paucity of data. The halo nucleus 11Be has been examined through the 10Be(d,p) reaction in inverse kinematics at equivalent deuteron energies of 12,15,18, and 21.4 MeV. Elastic scattering of 10Be on protons was used to select optical potentials for the analysis of the transfer data. Additionally, data from …

The applicability of Coulomb dissociation reactions to determine the cross section for the inverse neutron capture reaction was explored using the reaction Li-8(gamma,n)Li-7. A 69.5 MeV/nucleon Li-8 beam was incident on a Pb target, and the outgoing neutron and Li-7 nucleus were measured in coincidence. The deduced (n,gamma) excitation function is consistent with data for the direct capture reaction Li-7(n,gamma) Li-8 and with low-energy effective field theory calculations.

Faculty Publications

L-rhamnose (Rha) is a deoxy-hexose sugar commonly found in nature. L-Rha catabolic pathways were previously characterized in various bacteria including Escherichia coli. Nevertheless, homology searches failed to recognize all the genes for the complete L Rha utilization pathways in diverse microbial species involved in biomass decomposition. Moreover, the regulatory mechanisms of L-Rha catabolism have remained unclear in most species. A comparative genomics approach was used to reconstruct the L-Rha catabolic pathways and transcriptional regulons in the phyla Actinobacteria, Bacteroidetes, Chloroflexi, Firmicutes, Proteobacteria, and Thermotogae. The reconstructed pathways include multiple novel enzymes and transporters involved in the utilization of L-Rha and …

We analyze the planetary microlensing event MOA-2010-BLG-328. The best fit yields host and planetary masses of Mh = 0.11 ± 0.01 M Ȯ and Mp = 9.2 ± 2.2 M ⊕, corresponding to a very late M dwarf and sub-Neptune-mass planet, respectively. The system lies at D L = 0.81 ± 0.10 kpc with projected separation r ⊥ = 0.92 ± 0.16 AU. Because of the host's a priori unlikely close distance, as well as the unusual nature of the system, we consider the possibility that the microlens parallax signal, which determines the host mass and distance, is actually due …

Measuring Changes In Tactile Sensitivity In The Hind Paw Of Mice Using An Electronic Von Frey Apparatus, Tijana Martinov, Madison Mack, Akilah Sykes, Devavani Chatterjea

Faculty Publications

Measuring inflammation-induced changes in thresholds of hind paw withdrawal from mechanical pressure is a useful technique to assess changes in pain perception in rodents. Withdrawal thresholds can be measured first at baseline and then following drug, venom, injury, allergen, or otherwise evoked inflammation by applying an accurate force on very specific areas of the skin. An electronic von Frey apparatus allows precise assessment of mouse hind paw withdrawal thresholds that are not limited by the available filament sizes in contrast to classical von Frey measurements. The ease and rapidity of measurements allow for incorporation of assessment of tactile sensitivity outcomes …

Faculty Publications

Results for ab initio no-core shell model calculations in a symmetry-adapted SU(3)-based coupling scheme demonstrate that collective modes in light nuclei emerge from first principles. The low-lying states of Li6, Be8, and He6 are shown to exhibit orderly patterns that favor spatial configurations with strong quadrupole deformation and complementary low intrinsic spin values, a picture that is consistent with the nuclear symplectic model. The results also suggest a pragmatic path forward to accommodate deformation-driven collective features in ab initio analyses when they dominate the nuclear landscape. © 2013 American Physical Society.

BACKGROUND: Mental disorders account for six of the 20 leading causes of disability worldwide with a very high prevalence of psychiatric morbidity in youth aged 15-24 years. However, healthcare professionals are faced with many challenges in the identification and treatment of mental and substance use disorders in young people (e.g. young people's unwillingness to seek help from healthcare professionals, lack of training, limited resources etc.) The challenge of youth mental health for primary care is especially evident in urban deprived areas, where rates of and risk factors for mental health problems are especially common. There is an emerging consensus that …

Faculty Publications

We report a technique for encoding both amplitude and phase variations onto a laser beam using a single digital micro-mirror device (DMD). Using this technique, we generate Laguerre-Gaussian and vortex orbital-angular-momentum (OAM) modes, along with modes in a set that is mutually unbiased with respect to the OAM basis. Additionally, we have demonstrated rapid switching among the generated modes at a speed of 4 kHz, which is much faster than the speed regularly achieved by phase-only spatial light modulators (SLMs). The dynamic control of both phase and amplitude of a laser beam is an enabling technology for classical communication and …

Particulate matter (PM) is emitted during thermal decomposition of waste. During this process, aromatic compounds chemisorb to the surface of metal-oxide-containing PM, forming a surface-stabilized environmentally persistent free radical (EPFR). We hypothesized that EPFR-containing PM redox cycle to produce ROS and that this redox cycle is maintained in biological environments. To test our hypothesis, we incubated model EPFRs with the fluorescent probe dihydrorhodamine (DHR). Marked increases in DHR fluorescence were observed. Using a more specific assay, hydroxyl radicals ( •OH) were also detected, and their level was further increased by cotreatment with thiols or ascorbic acid (AA), known components of …

Long gamma-ray bursts (GRBs) have been linked to extreme core-collapse supernovae from massive stars. Gravitational waves (GW) offer a probe of the physics behind long GRBs. We investigate models of long-lived (∼10-1000 s) GW emission associated with the accretion disk of a collapsed star or with its protoneutron star remnant. Using data from LIGO's fifth science run, and GRB triggers from the Swift experiment, we perform a search for unmodeled long-lived GW transients. Finding no evidence of GW emission, we place 90% confidence-level upper limits on the GW fluence at Earth from long GRBs for three waveforms inspired by a …

Porites corals are foundation species on Pacific reefs but a confused taxonomy hinders understanding of their ecosystem function and responses to climate change. Here, we show that what has been considered a single species in the eastern tropical Pacific, Porites lobata, includes a morphologically similar yet ecologically distinct species, Porites evermanni. While P. lobata reproduces mainly sexually, P. evermanni dominates in areas where triggerfish prey on bioeroding mussels living within the coral skeleton, thereby generating asexual coral fragments. These fragments proliferate in marginal habitat not colonized by P. lobata. The two Porites species also show a differential bleaching response despite …

In a recent publication, we identified a line of Lifshitz transition points separating the Fermi liquid and pseudogap regions in the hole-doped two-dimensional Hubbard model. Here, we extend the study to further determine the superconducting transition temperature in the phase diagram. By means of large-scale dynamical cluster quantum Monte Carlo simulations, we are able to identify the evolution of the d-wave superconducting dome in the hole-dope side of the phase diagram, with next-nearest-neighbor hopping (t′), chemical potential, and temperature as control parameters. To obtain the superconducting transition temperature Tc, we employ two-particle measurements of the pairing susceptibilities. As t′ goes …

Exploring The " Dark Matter" Of A Mammalian Proteome By Protein Structure And Function Modeling, Michal Brylinski Dec 2013

Exploring The " Dark Matter" Of A Mammalian Proteome By Protein Structure And Function Modeling, Michal Brylinski

Faculty Publications

Background: A growing body of evidence shows that gene products encoded by short open reading frames play key roles in numerous cellular processes. Yet, they are generally overlooked in genome assembly, escaping annotation because small protein-coding genes are difficult to predict computationally. Consequently, there are still a considerable number of small proteins whose functions are yet to be characterized.Results: To address this issue, we apply a collection of structural bioinformatics algorithms to infer molecular function of putative small proteins from the mouse proteome. Specifically, we construct 1,743 confident structure models of small proteins, which reveal a significant structural diversity with …

Mean-Field Embedding Of The Dual-Fermion Approach For Correlated Electron Systems, S. X. Yang, H. Terletska, Z. Y. Meng, J. Moreno, M. Jarrell Dec 2013

Mean-Field Embedding Of The Dual-Fermion Approach For Correlated Electron Systems, S. X. Yang, H. Terletska, Z. Y. Meng, J. Moreno, M. Jarrell

Faculty Publications

To reduce the rapidly growing computational cost of the dual-fermion lattice calculation with increasing system size, we introduce two embedding schemes. One is the real fermion embedding, and the other is the dual-fermion embedding. Our numerical tests show that the real fermion and dual-fermion embedding approaches converge to essentially the same result. The application on the Anderson disorder and Hubbard models shows that these embedding algorithms converge more quickly with system size as compared to the conventional dual-fermion method, for the calculation of both single- and two-particle quantities. © 2013 American Physical Society.

Peer relationships are of central importance for healthy psychosocial development and functioning during childhood, adolescence, and adulthood. Peers provide unique opportunities for social-cognitive growth and the development and maintenance of social skills. They also serve as important sources of emotional and social support, can foster positive feelings about the self and others, and function protectively against the effects of interpersonal stressors (Rubin, Bukowski, & Parker, 2006). Without peer relationships, individuals might miss out on developmentally formative opportunities and experiences, such as acquiring certain socially competent skills and behaviors and forming intimate best friendships (Rubin, Coplan, & Bowker, 2009).

Social Regulation Of Male Reproductive Plasticity In An African Cichlid Fish, Karen P. Maruska, Russell D. Fernald

Faculty Publications

Social interactions with the outcome of a position in a dominance hierarchy can have profound effects on reproductive behavior and physiology, requiring animals to integrate environmental information with their internal physiological state; but how is salient information from the animal's dynamic social environment transformed into adaptive behavioral, physiological, and molecular-level changes? The African cichlid fish, Astatotilapia burtoni, is ideally suited to understand socially controlled reproductive plasticity because activity of the male reproductive (brainpituitary gonad) axis is tightly linked to social status. Males form hierarchies in which a small percentage of brightly colored dominant individuals have an active reproductive axis, defend …

D.A.R.E. Day! Implementing Evidence-Based Drug Education In An Adventist Educational Setting, Harvey J. Burnett Jr.

Faculty Publications

Since 1983, the Drug Abuse Resistance Education (D.A.R.E.) program has become one of the most popular and widely used school-based prevention programs to help empower youth to make responsible choices about drug use as well as to deal with violent behaviors such as bullying. Because young people in both Adventist and non-Adventist circles are often exposed to drugs through their peers, the media, or family members, incorporating programs like D.A.R.E. within the Seventh-day Adventist educational environment can provide a vital tool in equipping our young people to make responsible and safe choices about drugs.

Between the ages of 13 and 25, youth go through major psychosocial changes—forming their own identity, becoming independent of their parents, establishing intimate friendships and relationships, struggling with academic goals, and eventually starting a career and even a family. During this time, they can experience difficulties adjusting to these changes and the stresses that ac - company them, and as a result, make behavioral choices that are dangerous and even life destroying. To avoid destructive choices, young people need support from significant others throughout this stage of their lives. What can educators, parents, and church and community leaders do to …

Cross Amplification Of Microsatellite Loci Developed For Atractosteus Spatula In Atractosteus Tropicus, Sandra Bohn, Enrique Barraza, Caleb Mcmahan, Brian Kreiser

Faculty Publications

Due to recent population declines in tropical gar (Atractosteus tropicus), a greater understanding of its population structure is needed. A key step in gaining this understanding is the development of microsatellite loci for use in this species. For this purpose, 33 microsatellite loci from alligator gar (A. spatula) were screened in 52 individuals from a population in Zanjón del Chino, El Salvador. Twenty-five of these loci successfully amplified in this species, and 9 of those loci were polymorphic in this population. These loci should provide a useful tool for genotyping A. tropicus, both in studying …

Ramanujan's Master Theorem For The Hypergeometric Fourier Transform Associated With Root Systems, G. Ólafsson, A. Pasquale Dec 2013

Ramanujan's Master Theorem For The Hypergeometric Fourier Transform Associated With Root Systems, G. Ólafsson, A. Pasquale

Faculty Publications

Ramanujan's Master theorem states that, under suitable conditions, the Mellin transform of an alternating power series provides an interpolation formula for the coefficients of this series. Ramanujan applied this theorem to compute several definite integrals and power series, which explains why it is referred to as the "Master Theorem". In this paper we prove an analogue of Ramanujan's Master theorem for the hypergeometric Fourier transform associated with root systems. This theorem generalizes to arbitrary positive multiplicity functions the results previously proven by the same authors for the spherical Fourier transform on semisimple Riemannian symmetric spaces. © 2013 Springer Science+Business Media …

The level statistics of the spherical mean-field plus pairing model is investigated based on the exact solutions obtained from the extended Heine-Stieltjes correspondence. It is shown that the level statistics for 49Ca and 50Ca calculated from the model with single-particle energies and a pairing strength extracted from experimental data indeed exhibits a chaotic behavior within the phase transitional region, while most isotopes display regular spectra. © Owned by the authors, published by EDP Sciences, 2013.
