Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods

Simulation of thermal plant optimization and hydraulic aspects of thermal distribution loops for large campuses
Get PDFFollowing an introduction, the author describes Texas A&M University and its utilities system. After that, the author presents how to construct simulation models for chilled water and heating hot water distribution systems. The simulation model was used in a $2.3 million Ross Street chilled water pipe replacement project at Texas A&M University. A second project conducted at the University of Texas at San Antonio was used as an example to demonstrate how to identify and design an optimal distribution system by using a simulation model. The author found that the minor losses of these closed loop thermal distribution systems are significantly higher than potable water distribution systems. In the second part of the report, the author presents the latest development of software called the Plant Optimization Program, which can simulate cogeneration plant operation, estimate its operation cost and provide optimized operation suggestions. The author also developed detailed simulation models for a gas turbine and heat recovery steam generator and identified significant potential savings. Finally, the author also used a steam turbine as an example to present a multi-regression method on constructing simulation models by using basic statistics and optimization algorithms. This report presents a survey of the author??s working experience at the Energy Systems Laboratory (ESL) at Texas A&M University during the period of January 2002 through March 2004. The purpose of the above work was to allow the author to become familiar with the practice of engineering. The result is that the author knows how to complete a project from start to finish and understands how both technical and nontechnical aspects of a project need to be considered in order to ensure a quality deliverable and bring a project to successful completion. This report concludes that the objectives of the internship were successfully accomplished and that the requirements for the degree of Degree of Engineering have been satisfied
Molecular pathways mediating the development of female germ cells
Get PDFIn mice, primordial germ cells (PGCs) dramatically increase in their number from 200 cells at 9.5 dpc to 10 000 cells at 12.5 dpc with doubling time of 12.6 hours. Thus, cell proliferation of PGCs seems a unique compared to proliferation of other cell types. How Mastl (microtubule-associated serine/threonine kinase-like) is involved in the rapidly dividing PGCs is not known. PGC-specific deletion of Mastl resulted in a significant loss of PGCs by interfering with cell cycle progression beyond metaphase. This mitotic defect further led to the activation of DNA damage and the apoptotic cell death of Mastl-null PGCs by 12.5 dpc. Therefore, indicating that Mastl-mediated molecular events are indispensable for cell cycle progression in PGCs. However, the metaphase-anaphase transition defects observed in the Mastl-null PGCs is rescued by simultaneous deletion of Ppp2r1a ( subunit of PP2A). Collectively, our results indicated that the Mastl-PP2A axis plays a fundamental role in controlling PGCs proliferation. At 13.5 dpc, PGCs started to differentiate into female germ cells by entering prophase I of meiosis. Around the time of birth, the primordial follicles assembly occurs in mammalian ovary. In mice, there exist two classes of primordial follicles: the first wave of primordial follicles develops immediately after birth, whereas the second wave of primordial follicles activated later in adult life. To label and trace the in vivo development and activation of two waves (or classes) of primordial follicles, we used two different mouse models: Foxl2-CreERT2 and Sohlh1-CreERT2. Our study showed that the first wave of primordial follicles get exhausted around three months of age in mice. Additionally, this class of primordial follicles contributes to the onset of puberty and to early fertility in mice. On the other hand, the primordial follicles in the cortical region of the ovary are activated after three months of age of mice contributing to fertility until the end of reproductive life. One of the hallmarks of the activation of primordial follicles is a squamous-cuboidal transition of primordial follicle granulosa cells (pfGCs). However, how pfGCs–oocytes dialog regulate the activation of primordial follicles and determines their developmental fates are still unclear. To study this, we used Foxl2-CreERT2 mouse model to show that for maintenance of quiescence of primordial follicles, inhibition of mammalian target of rapamycin complex 1 (mTORC1) signaling in pfGCs is imperative. For this purpose, we deleted Tsc1 and Rptor from pfGCs, which caused over-activation and suppression of activation of primordial follicles respectively. Furthermore, our study also demonstrated that mTORC1-KITL cascade trigger the awakening of dormant oocytes in primordial follicles as initiated by cellular and molecular changes in pfGCs. Mammalian females are endowed with fixed number of primordial follicles in the ovaries, which are depleted gradually and menopause ensued with the exhaustion of pool of primordial follicles. However, many ovarian pathological conditions lead to premature ovarian failure due to early depletion of follicles pool. Therefore, the existence of OSCs (oogonial stem cells) in ovaries generated excitement in many females suffering from infertility resulting from various reproductions related ailments. This also changed the notion that OSCs might contribute to renewable of follicles as shown by OSCs purified from human and mouse ovaries by DDX4 antibody-based FACS. However, technically the isolation of OSCs by DDX4 antibody-based FACS is in controversy. To verify this claim, we followed the published reported method to isolate OSCs from human and mouse ovaries. Our results showed that isolated DDX4 positive cells from human ovary did not express any DDX4 mRNA as shown by single-cell mRNA sequencing analysis. Additionally, when these DDX4-positve cells were injected into SCID mice, no follicle formation was noted, thus refuting the reported evidence. Similarly, Ddx4-antibody based FACS sorted mouse ovarian cells also displayed an absence of Ddx4 mRNA and unable to generate follicles. Our results claimed that previously reported DDX4 positive ovarian cells purified from human and mouse are neither DDX4 expressing cells nor are they functional OSCs
Intern experience at CH���M Hill, Inc.: an internship report
Get PDFIncludes author's vita"Submitted to the College of Engineering of Texas A&M University in partial
fulfillment of the requirement for the degree of Doctor of Engineering."Includes bibliographical referencesA review of the author's internship experience with CH���M HILL, Inc.
during the period September 1975 through May 1976 is presented. During this nine month
internship the author worked as an Engineer II in the Industrial Processes discipline of this
large consulting engineering firm... The author's prime responsibility was as one of three
lead design engineers on the design of a large wastewater treatment facility for a pulp mill
in Hoquiam, Washington owned by ITT Rayonier Inc. The work generally consisted of the design
of individual treatment units and associated piping and pumping. The purpose of the project
was to provide wastewater treatment capabilities that would satisfy the effluent limitations
(standards) imposed upon the mill by the State of Washington Department of Ecology and the
U.S. Environmental Protection Agency. The author's assignment also entailed necessary
interaction with the project manager and other CH���M HILL design engineers and support staff
members, the client's representatives, and representatives of two other consulting engineering
firms working on the project. Thus, the internship position at CH���M HILL provided considerable
experience coordinating the author's work with the work of other engineers, guiding the design
and administrative efforts of a support staff, and interacting regularly with the client and
other consulting firms. This broad exposure to a variety of engineering and organizational
problems provided a valuable educational experience
Transition to turbulence in a qblique shock-wave/boundary-layer interaction at M=15
No full textDirect numerical simulations are carried out for different forcing techniques to trigger transition during the interaction between an oblique shock-wave and a laminar boundary-layer at M = 1.5. Three forcing methods are used: a) forcing of oblique unstable modes, whose shape and behaviour are determined by the local linear stability theory, b) broadband free-stream acoustic disturbances, and c) a cold plasma flow control device. While the oblique-mode breakdown is dominant for low-amplitude forcing, long streaky structures drive the transition process in a high-amplitude disturbance environment. LES are also performed on the experimental setup by the Institute of Theoretical and Applied Mechanics (ITAM) from Novosibirsk State University with cold plasma actuation. As well as the disturbance type, the effect of Reynolds number and forcing amplitude will be investigated
