Strategic Tools in Regenerative and Translational Dentistry.
Human oral-derived stem cells can be easily obtained from several oral tissues, such as dental pulp, periodontal ligament, from gingiva, or periapical cysts. Due to their differentiation potential, oral-derived mesenchymal stem cells are promising for tissue engineering and regenerative medicine. The regenerative ability showed by some oral tissues strongly depends on their sleeping adult stem cell populations that are able to repair small defects and to manage local inflammation. To date, researchers are working on effective and efficient methods to ensure safe and predictable protocols to translate stem cell research into human models. In the last decades, the challenge has been to finally use oral-derived stem cells together with biomaterials or scaffold-free techniques, to obtain strategic tools for regenerative and translational dentistry. This paper aims to give a clear point of view on state of the art developments, with some exciting insights into future strategies

Type inference through the analysis of Wikipedia links.
DBpedia contains millions of untyped entities, either if we consider the native DBpedia ontology, or Yago plus Word-Net. Is it possible to automatically classify those entities? Based on previous work on wikilink invariances, we wondered if wikilinks convey a knowledge rich enough for their classication. In this paper we give three contributions. Concerning the DBpedia link structure, we describe some measurements and notice both problems (e.g. the bias that could be induced by the incomplete ontological coverage of the DBpedia ontology), and potentials existing in current type coverage. Concerning classication, we present two techniques that exploit wikilinks, one based on induction from machine learning techniques, and the other on abduction. Finally, we discuss the limited results of classication, which conrmed our fears expressed in the description of general gures from the measurement. We also suggest some new possible directions to entity classication that could be taken

Dispelling the Myths Behind First-author Citation Counts
We 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

Busfield, MSU Assistant Professor of Speech and Theater, Meet the Author is designed to introduce a general audience to a contemporary author and their work through in-depth interviews. This episode features a conversation between Dr. Glendon Swarthout, prolific author and English professor at MSU, and assistant professors Sam S. Baskett and Theodore B. Strandness
The glucocorticoid in acute decompensated heart failure: Dr Jekyll or Mr Hyde?
Glucocorticoid administration is not recommended in
patients with heart failure because of its related sodium and
fluid retention. However, previous experimental and
clinical studies have demonstrated that glucocorticoids
can also induce a diuretic effect and improve renal
function in patients with acute decompensated heart failure
(ADHF) with refractory diuretic resistance. We report the
case of a 65-year-old man with a known diagnosis of
aortic stenosis, systolic ventricular dysfunction, and
chronic obstructive pulmonary disease who was admitted
for ADHF. After 3 days, during which resistance to
conventional therapy was observed, intravenous methylprednisolone
(60 mg/d) was added to ongoing medical
treatment. Three days after the onset of glucocorticoid
therapy, daily urine volume progressively increased (up to
5.8 L/d ). Concurrently, signs and symptoms of congestion
improved, the weight and brain natriuretic peptide plasma
levels decreased (−7 kg and −46%, respectively) and
glomerular filtration rate increased (+26%). Bioimpedance
vector analysis showed a net reduction of fluid content
(from 88.4% to 73.6% of hydration at discharge). In
conclusion, this case report suggests that in a patient with
ADHF and congestion resistant to diuretic therapy,
glucocorticoid administration is safe and associated with
improvement in congestion, neurohormonal status, and
renal function. These data support the possible usefulness
of glucocorticoids in this settin
Simulation of thermal plant optimization and hydraulic aspects of thermal distribution loops for large campuses
Following 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
