    <div class="html-content"><strong>What is your background in research?</strong><br>After my two successful research experiences combined with the research I am doing this summer, I was very confident of my capabilities to do research on-campus. I was able to complete both solo and group research projects as each summer presented a newer opportunity. <br><br><strong>How did you find a mentor and decide on a project? How did you know this was the project you wanted to do?</strong><br>My roommate is currently a returning URA Scholar and fellow Meyerhoff Scholar. He linked me up with his mentor to pursue a project that was in my realm of research interests. After meeting with him about the potential project, I was even more excited for his vision, direction, and contributions into real-world applications. <br><br><strong>What academic background did you have before you started on this research?</strong><br>This past semester, I successfully completed three Computer Engineering courses for my major. I plan to use the knowledge I gained from these courses to help develop my research. In addition, I plan to use the concepts learned from my courses this semester. <br><br><strong>Was the application hard? Did your mentor help you?</strong><br>As a whole, I found the URA application to be moderately easy. I was able to get assistance from my mentor to help formulate the abstract and some of the additional details of the project.<br><br><strong>What is your advice to other students about getting involved in research?</strong><br>Have patience! In the process, there are times where it can and will become frustrating. Sometimes getting some fresh air or even setting mini leisure-time can help clear one's thoughts and open up the mind more.<br><br><strong>What are your career goals?</strong><br>Post-undergraduate education, I would like to obtain my PhD in Electrical Engineering. I plan to either teach in academia and/or continue to do research. I will take each day one step at a time. <br><br><strong>About my research:</strong><br>In this research we propose an innovative method for standoff chemical detection, using the techniques of photo-acoustic sensing and high sensitivity microphone arrays for acoustic beam-forming and noise rejection. Acoustic beam-forming is a technique used to detect signals along the formed beam while rejecting and filtering surrounding noise outside the regions covered by the beam. Similar to phase array antenna characteristics, we can form receiving beams using a 2D microphone array. The more microphone elements in the array, the narrower the receiving beam becomes (higher directivity). Our plan will be to use an array of four microphones and collect their signals simultaneously using a multi-channel A-to-D unit. The collected signals will be processed in real time with a delay time constant training section and will also achieve ambient noise cancellation and signal enhancement.<br><br></div>

    <div class="html-content"><strong>How did you find a mentor and decide on a project? How did you know this was the project you wanted to do?</strong><br>Around the time I was entering UMBC as a freshman, I was deeply interested in the field of regenerative medicine. I came across Dr. Leach’s research on the Chemical Engineering Department website and immediately started reading publications and reviews. I found every single research topic interesting and after meeting with Dr. Leach, we found the perfect project.<br><br><strong>What academic background did you have before you started on this research?</strong><br>My experience in several summer research internships as well as knowledge from my science courses definitely helped in understanding my research project.<br><br><strong>What has been the hardest part about your research? </strong><br>As with all research experiences, it is easy to get caught up in all the experiments and freak out when you hit a roadblock. However, this is easily managed by taking two seconds to realize that everyone goes through some sort of frustration in research.<br><br><strong>What is your advice to other students about getting involved in research?</strong><br>Research is exciting. No matter what your interests or major may be, there is always a question that needs an answer. If a student has the opportunity to conduct research, they should give it a shot.<br><br><strong>What are your career goals?</strong><br>I plan to pursue a PhD in biomedical engineering and conduct research in either an industrial or academic setting.<br><br>Neurons grow and develop in the three-dimensional (3D) environment of the developing embryo. Previous work from our group has demonstrated that culturing embryonic neurons in 3D matrices allows the cells to respond in a way that more closely resembles natural development than traditional 2D culture. Cells interact with their extracellular matrix and sense the dimensionality of their surroundings via integrin receptors on the cell surface that bind to matrix molecules, initiate intracellular signaling cascades and affect changes in cell shape and function. My work focuses on elucidating the signaling events that regulate these changes in cell response. We hypothesize that 3D environments impose changes in matrix-ligand organization and alter neuronal behavior by modulating β1-integrin cytoskeleton signaling. To test this hypothesis we culture PC12 cells, a neuronal cell model, on 2D and within 3D collagen substrates and probe the signaling response by inhibiting several key signaling molecules involved in regulating neuron morphology: β1-integrin, Focal Adhesion Kinase (FAK), and an activated form of FAK that is phosphorylated at tyrosine 397. Immunocytochemistry techniques and fluorescent microscopy will be used to analyze the effect of inhibiting these signalingN molecules on neuronal behavior. The results of this experiment will identify the key signaling mechanisms in 3D neuronal culture and provide a biological basis for testing new biomaterial-based therapeutics.</div>

<Title>Used, Rental, Digital, New, Looseleaf? Choices Abound When Selecting Textbooks</Title>
<Body>
<![CDATA[
    <div class="html-content"><p>The UMBC Bookstore is excited to offer students more choices than ever before when it comes to purchasing course materials for their classes.  With the expansion of its  popular textbook rental program, the store now offers over 3 times as many books for rent than last semester.  The recent implementation of a new software application ensures the process of renting is easier and faster, allowing students to sign the <a title="Click to view the Rental Agreement terms" href="http://www.umbc.edu/bookstore-data/docs/umbcrentalagreement.pdf" rel="nofollow external" class="bo">Rental Agreement</a> at the cash register pin pad.</p>
    <p>When determining what choices to purchase students are encouraged to take into account the potential buyback price at the end of the semester.  For example, if the Western Civilization V.1 textbook below is readopted for the spring semester, the Bookstore would pay about $54 to students at the end of the term for that text.  If the student purchased a used copy for $81, <strong>the net cost for using the book the entire semester would only be $27</strong>.</p>

<Title>150th Anniversary of the Civil War's First Battle of Bull Run</Title>
<Body>
<![CDATA[
    <div class="html-content"><p>150 years ago this past April, the United States began its most trying and desperate hour.  In the wake of the secession of eight Southern States from the Union, government and military leaders in the North understood that, in order to preserve the Union, the South would have to be invaded.  President Abraham Lincoln called for 75,000 volunteers to serve for 90 days.  His call for volunteers caused four more states to secede, including Virginia.  He believed that one great victory in battle would end the war.  That victory did not come, but the ground chosen for that battle would take a prominent place in the annals of the history of the United States of America.</p>
    
    <p>July 21, 2011 marks the sesquicentennial of the First Battle of Bull Run, or First Manassas, and the Special Collections Department of the Albin O. Kuhn Library has information regarding this and many other Civil War topics.  Whether you are a researcher, historian, or a Civil War enthusiast, Special Collections has many resources that can guide you through an historic event as if you were there yourself.</p>

    <p>The first 3 months of The War Between the States saw only skirmishes between small units of the combatants' armies.  However, on July 21, 1861, the two unproven and untried armies met in battle on a grand scale for the first time.   The Union Army was ordered to march on the Confederate capitol of Richmond, VA, while the Confederate army took up defensive positions just 25 miles southwest of Washington, D.C. along the Bull Run Creek in the town of Manassas, VA.  Manassas was an important railroad junction which the Union Army needed to capture to facilitate the successful invasion of the South. <br><br><br><br><br></p>
    
    <p><br> <img alt="76-05-083.jpg" src="http://www.umbc.edu/blogs/library/76-05-083.jpg" width="349.5" height="309" style="max-width: 100%; height: auto;">In order to bypass the enemy's defenses, the Union commander, General Irvin McDowell, decided to attempt to cross the creek at an undefended spot to the north west of the Confederate positions.  The ford near Sudley Springs provided access for the Union troops to breach the defenses and engage the enemy.</p>

    <em>Sudley Springs, Bull Run</em> <a href="http://contentdm.ad.umbc.edu/cdm4/item_viewer.php?CISOROOT=/test1&amp;CISOPTR=113&amp;CISOBOX=1&amp;REC=1" rel="nofollow external" class="bo">click here for image</a> <br><br><br></p>
    
    <p><br><br><br><br><br><br>The battle contained some famous exploits, including those of Brigadier General Thomas J. Jackson, who earned his illustrious moniker because his brigade stood their ground like a “stonewall.”  The man who allegedly gave him that nickname was Southern General Bernard Bee, who was mortally wounded not long after.  His friend, Colonel Francis Bartow, was also killed nearby.  Today there are monuments marking these spots.  </p>

    <p>Jackson made his stand along a ridge not far from the Henry House, around which occurred much of the fighting.  The house was very badly damaged and the tenant, 85 year old widow Judith Henry, was killed.  Afterwards the Henry house was demolished and rebuilt. It is interesting to compare our photo of the house with the modern one.

    <p>In 1865, a monument was erected by Union veterans to honor the dead of the First Battle at Bull Run, and Special Collections has the very moment captured on film. Today the monument stands just behind the Henry House, and it can be seen in our photo of the house, which means our photo must have been taken after 1865. <br> <br>  <img alt="77-12-100.jpg" src="http://www.umbc.edu/blogs/library/77-12-100.jpg" width="314" height="268.5" style="max-width: 100%; height: auto;"> <br><em>Dedication of monument on Bull Run battle-field</em> <a href="http://contentdm.ad.umbc.edu/u?/test1,252" rel="nofollow external" class="bo">click here for image</a></p>

<![CDATA[
    <div class="html-content">The central dogma of molecular biology states that DNA is “transcribed” into RNA, which is then “translated” into protein. Proteins are made by linking together a series of units called amino acids; errors can occur when the information in the RNA is misinterpreted leading to the incorporation of the wrong amino acid. This phenomenon, termed “misreading” is our laboratory’s main interest. A small RNA called a transfer RNA (tRNA) is responsible for decoding the RNA. Our laboratory has developed an enzyme-based reporter system to measure misreading rates. The lacZ gene encoding the enzyme beta-galactosidase was mutated to produce an enzyme lacking significant activity. Misreading of the mutant gene can restore activity. The rate of misreading is equal to the ratio of the mutant enzyme activity to wild type activity. In bacteria, misreading occurs at a rate of about 1 in 1000 to 1 in 10,000. This research seeks to determine what the error rate is in human cells using this system. We propose to insert the lacZ gene from bacterial plasmids into plasmids that can be used in HeLa cells, which are immortal human tissue culture cells. A similar method of misreading analysis will be applied to the human cells’ beta-galactosidase activity in order to understand errors in cell machinery during the process of protein production.</div>

<![CDATA[
    <div class="html-content">This research investigates how the frequency of  portfolio rebalancing affects the risk and return of an investor’s  portfolio.  Portfolio rebalancing refers  to reallocation between asset classes to match the targeted portfolio allocations.  Increases or decreases in asset values over  time will cause actual asset holdings to differ from targeted allocations.  Popular portfolio allocations will be  simulated using U.S. data on asset class returns, such as stocks and bonds,  over the time period from 1926-2009.  For  each portfolio, a sensitivity analysis will be conducted to determine how risk  and return are affected by different rebalancing frequencies.  One, two, three, four and five year  rebalancing frequencies will be used.   For each portfolio and rebalancing period, the average return, standard  deviation of return (which measures risk) and Sharpe Ratio (the standard  risk-return statistic) will be calculated.   The optimal rebalancing period will be the one that maximizes the Sharpe  Ratio.  Additionally, these portfolios  and sensitivity analyses will be constructed for multiple time frames within  the range of 1926-2009.  Using  information from multiple time frames can help assess whether the optimal  rebalancing period is consistent, and account for differences in returns on different  assets during different time periods.   Knowing whether there is an optimal time frame to rebalance a portfolio  is important for portfolio management decisions because it is a variable that managers of portfolios must consider.</div>

<![CDATA[
    <div class="html-content">The prostate  is a male accessory sex gland that stores and secretes proteins into the seminal  fluid during ejaculation. Prostate cancer accounts for approximately 30,000  deaths annually in the United States alone. A number of genes have been  implicated in the origin and progression of prostate cancer. One possible  mechanism in human prostate cancer involves both the activation of an oncogene (<em>MYC</em>) and the loss of function of a  tumor suppressor gene (<em>PTEN</em>). Mouse  models based only on the overexpression of <em>MYC</em> or the loss of function of <em>Pten</em> have  been derived. However, no mouse model exists in which both these events are  replicated. The aim of this study was to generate prostate-specific activation  of <em>MYC</em> and the loss of <em>Pten</em> in a single mouse model. To achieve  this goal, we have taken advantage of a prostate-specific <em>Hoxb13</em> promoter to drive the <em>MYC</em> oncogene (Hoxb13/MYC) and <em>Cre</em> recombinase (Hoxb13/Cre) with a floxed <em>Pten</em> mouse. Mice carrying these modifications were interbred and their progeny  analyzed by Southern blot and PCR techniques for inheritance of all three  transgenes. To date, we have identified mice that carry all three alleles. We  are waiting for phenotypic analysis of these mice in terms of development of prostate cancer.</div>
