PURPOSE: Preterm infants frequently experience oral feeding difficulties due to underdeveloped oral motor skills and the lack of coordination of sucking, swallowing, and respiration. The infants' ability to consume all feedings orally while maintaining physiologic stability and weight gain is necessary for their discharge. Therefore, difficulty with oral feeding leads to longer hospital stays and higher costs. For example, with more than half a million of premature infants born each year, a 3-day decrease in hospital stay would save more than 2 billion dollars annually. There is a need for evidencedbased interventions that facilitate development of oral-motor skills, leading to improved oral feeding, thus shortening hospital stays and lowering costs. The purpose of this research was to test the newly developed Premature Infant Oral Motor Intervention (PIOMI) beginning at 29 weeks postmenstrual age (PMA), before oral feedings were introduced, to determine whether the prefeeding intervention would result in a shorter transition from gavage to total oral feedings and a shorter length of hospital stay (LOS). The PIOMI is a 5-minute oral motor intervention that provides assisted movement to activate muscle contraction and provides movement against resistance to build strength. The focus of the intervention is to increase functional response to pressure and movement and control of movements for the lips, cheeks, jaw, and tongue. The cheeks (internal and external), lips, gums, tongue, and palate were stimulated per specific protocol with finger stroking. SUBJECTS: A total of 19 infants from 1 level III NICU born between 26 and 29 weeks PMA: 10 in the experimental group and 9 in the control group. DESIGN: A randomized, blinded, clinical trial was conducted to examine outcomes related to the newly developed PIOMI. METHODS: Beginning at 29 weeks PMA (and before the introduction of oral feeding), the experimental group received the PIOMI for 5 minutes per day for 7 consecutive days. The control group received a sham intervention to keep staff and parents blinded to the infants' group assignment. Physiological and behavioral stabilities were continually assessed throughout the intervention. A chart review was then conducted to compare the transition from gavage feeding to total oral feedings between the experimental and control group, as well as LOS. RESULTS: The PIOMI was well tolerated by 29-week PMA infants, as evidenced by physiological and behavioral cues. Infants who received the once-daily PIOMI transitioned from their first oral feeding to total oral feedings 5 days sooner than controls (P = .043) and were discharged 2.6 days sooner than controls. CONCLUSION: This pilot work supports further study on the use of the PIOMI with preterm infants to enhance oralfeeding skills and decrease LOS.

The skeletogenesis and osteology of the syncranium of the redeye tetra Moenkhausia sanctaefilomenae is described. Skeletal development is rapid, with many elements of the chondrocranium and splanchnocranium well formed prior to the onset of ossification. The chondrocranium develops from an initial set of cartilaginous precursors, and continued elaboration proceeds from a series of processes which expand and converge to form the floor of the cranial vault, the otic capsule, the supraorbital bridge and the ethmoid region. Prodigious growth is observed for a number of splanchnocranial elements, including the Meckel's cartilage and the ceratohyal cartilage. Ossification occurs in overlapping phases with initial ossification of the jaws and neurocranial floor followed by the splanchnocranium, the supraorbital bridges and the ethmoid and cranial vault. Teeth are observed primarily on the premaxilla and dentary, while a single tooth is present on the maxilla. Particular cartilages, which had originally formed in the early larva, appear to degenerate and have no ossified representative in the adult syncranium. The cranial development for M. sanctaefilomenae is compared to those of other characiforms. © 2012 The Fisheries Society of the British Isles.

In this paper the variational Lyapunov method is developed for Caputo fractional differential equations. Further, the comparison theorems are proved with a relaxed hypothesis: the assumption of local Holder continuity is relaxed to Cp continuity of the functions involved in the Riemann-Liouville fractional differential equations. In this process the Grünwald-Letnikov derivative is used to define Dini derivatives. Also, a relation between ordinary and fractional differential equations is given. © 2011 Elsevier Ltd.

With this award from the Major Research Instrumentation Program, Professor Ram Mohan from Illinois Wesleyan University and colleagues Rebecca Roesner and Brian Brennan will acquire a 400 MHz NMR spectrometer. The proposal is aimed at enhancing research training and education at all levels, especially in areas such as (a) so-called environmentally friendly organic synthesis using bismuth and iron compounds as catalysts; (b) therapeutics for sickle cell disease; and (c) development of azamacrocyclic receptors for polyoxometalates.
Nuclear Magnetic Resonance (NMR) spectroscopy is one of the most powerful tools available to chemists for the elucidation of the structure of molecules. It is used to identify unknown substances, to characterize specific arrangements of atoms within molecules, and to study the dynamics of interactions between molecules in solution. Access to state-of-the-art NMR spectrometers is essential to chemists who are carrying out frontier research. The results from these NMR studies will have an impact in synthetic organic/inorganic chemistry, materials chemistry and biochemistry. This instrument will be an integral part of teaching as well as research at Illinois Wesleyan University and neighboring institutions such as the local community college (Heartland Community College).

This project comprises a systematic study of the Jovian Trojan Asteroids, which lead and trail Jupiter at its stable Lagrange points. The study will test or constrain models suggesting that the Trojans formed in situ and others suggesting they were scattered from greater heliocentric distances. The proposing team will use 4-color (BVRI) optical photometry to distinguish the major compositional groups known among the Trojans from each other, and from compositional groups in the main asteroid belt. They will obtain BVRI colors of up to 200 Trojans and time-resolved light curves of up to 75, bringing the number of well-determined Trojan light curves close to 200, and will test whether different compositional groups have different rotation parameters, indicating either differences in material strength or collisional history. The team plans to compare the properties of the Trojans with main belt asteroids, Cybeles and Hildas (neighboring groups on the outer edge of the main belt), Kuiper Belt objects, and cometary nuclei. This Research in Undergraduate Institutions project will directly involve undergraduate students in the research as well as support the dissertation of a graduate student at a collaborating institution. Some of these students will be women and/or members of underrepresented groups. The methods and results will be incorporated into undergraduate classes reaching up to 300 students per year taught by the Principal Investigator and collaborators, who are frequent speakers in public outreach forums.

This work aims to answer the question: what happens when an electron (one of the fundamental building blocks of all atoms) scatters from an atom or molecule in the presence of light from a laser? One of the simplest classes of things that can happen is elastic scattering in which the electron and the atom do not exchange energy and continue on their way after the collision with the same energies that they had before the collision (but perhaps changing their direction). These are called laser-assisted free-free (LAFF) processes because the electron is free (i.e., not bound to an atom or molecule) both before, and after, the collision. This work will involve experimental LAFF studies, with the broad aim of increasing our basic understanding of these processes. Particular attention will be paid to resolving long-standing discrepancies between theory and experiment (there are several sets of experimental data that have defied theoretical explanation for over twenty years) and examining how two-color laser fields affect, and can be used to control, scattering processes. In addition to the advancement of our basic understanding of scattering processes, this work has applications to a variety of fields, both basic and applied. For example, similar processes are important for understanding the interiors and atmospheres of stars. Free-free transitions also play a major role in the gas breakdown that occurs in electrical discharges, and provide a method for laser heating of a plasma (a gas of ionized atoms). Understanding these processes helps form a more solid scientific foundation for the field of plasma physics which underlies the manufacturing of the microelectronics at the heart of our computers and cell phones. This work will primarily take place at an undergraduate institution, and will directly involve several undergraduate students in research.
To accomplish the above stated aims, two different sets of experimental LAFF studies will be performed. The first set of experiments will continue this groups previous work which is well described by theory in spite of the fact that some similar experiments done by another group contradict current theoretical understanding. There are three significant differences between the experiments performed by the two groups: the electron energy, the photon energy, and the photon polarization. The new experiments will investigate a range of incident energies, as well as geometries that have not previously been investigated; e.g., laser propagation direction perpendicular to the scattering plane, and laser polarization direction perpendicular to the scattering plane. Essentially, the experiments will go from perturbative, to non-perturbative regimes. This data will test current theory, as well as provide insight to the development of more complex theoretical descriptions of the LAFF processes. In addition, the new experiments will look for interference effects in LAFF experiments that use a two-color (photon energy = 1.17 eV, and 2.34 eV) laser field. Electrons scattered in such a two-color field that have an energy 2.34 eV below the elastic peak may have emitted either a single 2.34 eV photon or two 1.17 eV photons. The research group will perform experiments that vary the relative phase of these two colors to observe predicted interference effects.

This project will study the millimeter/sub-millimeter optical properties of cosmic analog dusts at low temperatures. A dry cryocooler will be purchased so that work on this project can continue, free from the expenses of perishable cryogens. In addition, a Fourier Transform Spectrometer, designed specifically for this work, will be constructed in PIs research lab. Once these apparati are in place, the mm/sub-mm opacity and emissivity of many dust samples, made internally or obtained from external groups will be measured, using an innovative program of study. The main goals of this work are to (A) utilize the rich set of tools and expertise developed within the observational cosmology community to measure the above properties to unprecedented accuracy, (B) analyze dust species produced by different methods and different investigators under the same experimental conditions in order to clearly understand common trends and basic difference between the samples, and (C) implement an efficient experimental scheme for analyzing a large number of dust candidates, which would naturally lead to the creation of a database on the measured properties.
At visible wavelengths, dust obscures many interesting astronomical environments such as molecular clouds, star forming regions, young and old stars enveloped by dust, and young ultra-luminous galaxies in the early universe. The mm/sub-mm spectral region is a good regime to study these objects because dust is more transparent at these wavelengths. Information on the nature of interstellar dust is useful in and of itself because dust is an important component in galactic and stellar evolution as well as in the complex chemistry present in space that ultimately gives rise to prebiotic molecules, and this information can reveal more about the nature the objects/environments that are obscured by dust. Recent laboratory studies have shown that the properties of dust in the mm/sub-mm spectral region is more complicated than previously thought. Therefore, detailed studies dust species that can serve as analogs for cosmic dust such as those that will be undertaken in this project are needed before astronomical data on such environments can be interpreted with any confidence. This need has been intensified recently due to the availability high-quality mm/sub-mm data from new observatories such as the Atacama Large Millimeter/Submillimeter Array.

Social exclusion has powerful negative consequences and harmful costs affecting mental and emotional well being. This research project advances understanding of social exclusion by examining the patterns of brain activation present during social interactions that lead to exclusion in combination with self-reported emotions measured after exclusion has occurred. In order to accomplish this, the current project will vary the nature of exclusionary social interactions by altering: how frequently participants are included, how long the periods of exclusion last in each interaction, and when exclusion takes place during the social interactions. In addition, participants social exposure to exclusion is varied prior to their own interactions by having them witness others social exclusion. After witnessing others social exclusion, participants engage in a social interaction with those who were previously excluded in the observed interaction or they interact with the people who caused the observed exclusion. Ultimately, this research examines the effects of the degree of exclusion and the subsequent amount of social re-inclusion on patterns of brain activation and measures of participants feelings to learn more about how people recover from being socially excluded by others. By investigating how exclusion develops, these researchers will be able to understand and eventually predict the subtle cues or changes in social interactions that lead to perceptions of exclusion as well as the negative consequences of those perceptions over time.
Findings from this research will benefit the larger scientific community and society, and will also enhance the training and learning of the undergraduate students who are involved in the research by exposing them to opportunities to present the data, field questions, and explain the impact of the findings. Because Illinois Wesleyan University is a four-year liberal arts school, undergraduates will carry out all of the proposed research projects. At least half of these students have been women and this contributes to gender diversity in neuroscientific research. This proposal will increase awareness of the psychological impact of social exclusion as well as increase enthusiasm for graduate school and careers in science among students. These findings will be disseminated broadly through the preparation of manuscripts, abstracts, and conference presentations.
