A comparison between PARAMICS and VISSIM in estimating automated field‐measured traffic conflicts at signalized intersections
Authors: Essa Mohamed , Sayed Tarek 
Published: April 2016

SummaryThe main objective of this study is to investigate the relationship between field‐measured conflicts and simulated conflicts estimated from microsimulation model (PARAMICS) using the surrogate safety assessment model. An urban signalized intersection was selected for analysis. Automated video‐based computer vision techniques were used to identify field conflicts. The applicability of a two‐step model calibration procedure applied to VISSIM in a recent study was investigated using PARAMICS. In the first calibration step, the PARAMICS model was calibrated to ensure that the simulation gives reasonable results of average delay times. The second calibration step used a genetic algorithm procedure to calibrate PARAMICS parameters to enhance the correlation between simulated and field‐measured conflicts. Finally, the results obtained from PARAMICS were compared with results obtained from VISSIM. The comparison included three aspects: (i) the car‐following model and safety‐related parameters; (ii) the correlation between simulated and field‐measured conflicts; and (iii) the conflict spatial distributions. The results show that the default simulation model parameters give poor correlation with the field‐measured data, and therefore, using simulation models without a proper calibration should be avoided. Overall, good correlation between field‐measured and simulated conflicts was obtained after calibration for both models, especially at higher time‐to‐collision (TTC) values. At TTC threshold of 1.5 s, PARAMICS overestimates the number of conflicts and VISSIM underestimates it. Both models overestimated the number of conflicts at TTC threshold of 3.00 s. There were major differences between field‐measured and simulated conflicts spatial distributions for both simulation models. This indicates that despite the good correlation obtained from the calibration process, both PARAMICS and VISSIM do not capture the actual conflict occurrence mechanism.

Published: April 2016

AbstractIn this study, published experimental works on catalytic transesterification were analyzed to determine the most important variables affecting fatty acid conversion and the most suitable ranges of these variables for high performance. A database of 1324 data points was constructed from the experimental results in 31 representative papers published between 2008 and 2014, and this database was analyzed using artificial neural network (ANN) and decision tree (DT) techniques. It was found from ANN analysis that the most important variable for high fatty acid conversion was reaction time (with about 40% relative importance) followed by catalyst loading, alcohol:oil molar ratio, operating temperature, and support type with similar relative importance (about 10% each). DT analysis revealed 14 combinations of conditions leading to high performance, and some of these seemed to be generalizable for the use for the future studies; some heuristics were also derived from these generalizable conditions. © 2016 Society of Chemical Industry and John Wiley & Sons, Ltd
Enzymatic conjugation of multiple proteins on a DNA aptamer in a tail‐specific manner
Authors: Takahara Mari , Hayashi Kounosuke , Goto Masahiro , Kamiya Noriho 
Published: April 2016

AbstractConjugation of single‐strand DNA aptamers and enzymes has been of great significance in bioanalytical and biomedical applications because of the unlimited functions provided by DNA aptamer direction. Therefore, we developed efficient tailing of a DNA aptamer, with end‐specific conjugation of multiple enzymes, through enzymatic catalysis. Terminal deoxynucleotidyl transferase (TdT) added multiple Z‐Gln‐Gly (Z‐QG) moieties to the 3′‐end of a DNA aptamer via the addition of Z‐QG‐modified deoxyuridine triphosphate (Z‐QG‐dUTP) and deoxynucleoside triphosphates (dNTPs). The resultant (Z‐QG)m‐(dN)l‐aptamer, whose Z‐QGs with dN spacers served as stickers for microbial transglutaminase (MTG), were crosslinked between the Z‐QGs on the DNA and a substrate peptide sequence containing lysine (K), fused to a recombinant enzyme (i.e. bacterial alkaline phosphatase; BAP) by MTG. The incorporation efficiency of Z‐QG moieties on the aptamer tail and the subsequent conjugation efficiency with multiple enzyme molecules were dramatically altered by the presence of dNTPs, revealing that a combination of Z‐QG‐dUTP/dTTP comprised the best labeling efficiency and corresponding properties during analytical performance. Thus, a novel optimized platform for designing (BAP)n‐(dT)l‐DNA aptamers was demonstrated for the first time in this article, offering unique opportunities for tailoring new types of covalent protein‐nucleic acid conjugates in a controllable way.

ABSTRACTNew, deoxyribonucleic acid (DNA) based compounds, functionalized with hexadecyltrimethylammonium chloride (CTMA) and lanthanide hydroxide nanoparticles were synthesized. The spectral measurements suggest that between the DNA‐CTMA complex and the lanthanide (III) ions a chemical interaction takes place. The obtained materials exhibit an improved fluorescence efficiency, showing a potential interest for application in photonics, and more particularly, in light emitting devices. © 2016 Wiley Periodicals, Inc.

Published: April 2016

AbstractIntroductionSystemic malignant diseases cause the induction of autoimmunity, for example, paraneoplastic syndromes. There are no proofs of paraneoplastic syndromes in primary brain tumors. The aim of the study was to evaluate the involvement of the peripheral nervous system, together with an assessment of onconeuronal and antineural antibodies as indicators of humoral immune response against nervous system in patients with primary brain tumors.Materials and MethodsClinical examinations, electrophysiological studies of peripheral nerves (motor and sensory conduction velocity studies, conduction velocity distribution tests, thermal and vibratory quantitative sensory tests, and sympathetic skin response tests) and muscles, blood sampling collection (assessment of onconeuronal, and antineural antibodies) were performed on 33 patients with newly recognized primary brain tumors within 2–4 days after their admission to our department.ResultsWe revealed statistically significant changes of peripheral nerves, more pronounced in the peroneal nerve in standard and conduction velocity distribution tests, as well as in sympathetic skin responses. We revealed significantly higher vibratory thresholds, and pain thresholds for cold and warm in the upper and lower limbs in the study group than in the controls. In five patients, we have identified anti‐neuroendothelium, anti‐GFAP, anti‐MAG, anti‐PCNA, and anti‐Ro52 antibodies.ConclusionsIn patients with primary brain tumors, electrophysiological changes in peripheral nerves, together with the presence of the antineural antibodies suggest an autoimmune humoral response, and make the diagnosis of paraneoplastic neurological syndrome possible.
Removal of Selected Metals from Wastewater Using a Constructed Wetland
Authors: Šíma Jan , Svoboda Lubomír , Pomijová Zuzana 
Published: April 2016

Removal of selected metals from municipal wastewater using a constructed wetland with a horizontal subsurface flow was studied. The objective of the work was to determine the efficiency of Cu, Zn, Ni, Co, Sr, Li, and Rb removal, and to describe the main removal mechanisms. The highest removal efficiencies were attained for zinc and copper (89.8 and 81.5%, respectively). It is apparently due to the precipitation of insoluble sulfides (ZnS, CuS) in the vegetation bed where the sulfate reduction takes place. Significantly lower removal efficiencies (43.9, 27.7, and 21.5%) were observed for Li, Sr, and Rb, respectively. Rather, low removal efficiencies were also attained for Ni and Co (39.8 and 20.9%). However, the concentrations of these metals in treated water were significantly lower compared to Cu and Zn (e.g., 2.8 ± 0.5 and 1.7 ± 0.3 μg/l for Ni at the inflow and outflow from the wetland compared to 27.6 ± 12.0 and 5.1 ± 4.7 μg/l obtained for Cu, respectively). The main perspective of the constructed wetland is the removal of toxic heavy metals forming insoluble compounds depositing in the wetland bed. Metal uptake occurs preferentially in wetland sediments and is closely associated with the chemism of sulfur and iron.
Who enrolls in competency‐based education? An examination of the demographics and finances of competency‐based education programs
Authors: Kelchen Robert 
Published: April 2016

BackgroundThe concept of competency‐based education (CBE), in which some or all of a student's progression through a degree program is separated from the traditional credit hour model, has gained popularity in the last few years. However, little research has examined the types of students who enroll in CBE programs and whether CBE results in cost savings for different groups of students.MethodsIn this paper, I examine some of the first colleges with CBE programs and detail their student bodies, pricing structures, and whether CBE programs represent a lower‐cost route to a degree than traditional programs for students with financial need.ResultsI find that while CBE programs can result in significant cost savings for students making quick progress toward a degree, traditional models may be better for low‐income students taking fewer courses per year. However, as more CBE programs become eligible to receive federal financial aid dollars, CBE programs can make financial sense for more students.ConclusionLittle research has been done on the details of CBE, and more is needed before programs enroll a larger percentage of students. I suggest additional research on the cost of providing CBE degrees, as well as a closer examination of what types of students and programs are well‐suited to competency‐based models.

Authors: Todd R.L. , Moon N.W. , Langston C. 
Published: April 2016

BackgroundCommunication and learning technologies to enable mentoring for students are important topics for online courses and competency‐based education approaches. However, research results have been limited. The Georgia STEM Accessibility Alliance (GSAA) is a research project of the US National Science Foundation's Research in Disabilities Education (RDE) program. It is a collaborative RDE Alliance between the University of Georgia (UGA) and the Georgia Institute of Technology. Launched in 2010, GSAA seeks to enhance achievement of people with disabilities in STEM education and careers.MethodsCore GSAA features are the use of virtual worlds, online, and smartphone technologies to enhance student success through mediated mentoring, collectively referred to as the BreakThru project.ResultsGeorgia STEM Accessibility Alliance enrolled between 74 and 99 secondary and postsecondary mentees during its 4 years of mentoring activities. Participants involved in these activities reported a higher frequency of usage with communications platforms with which they were already acquainted, including e‐mail, telephone, and SMS text messaging. Positive changes in these students’ internal characteristics (self‐advocacy, self‐determination, science and math anxiety, and intention to persist) also were documented.ConclusionsPreliminary results from BreakThru can help inform course designers to maximize mentor/faculty effectiveness with students. Project results indicate both an improvement of student persistence and an improved skill in navigating critical transition points to employment.

AbstractA novel chemoselective ligation methodology has been developed for the facile construction of peptide‐based fluorescent probes. Furan‐containing peptides were activated by singlet oxygen and covalently engaged by nitrogen nucleophiles to yield stable conjugates. Singlet oxygen was compatible with sensitive amino acid residues within the peptides and a range of fluorophores, bearing different functionalities, were successfully incorporated, illustrating the broad scope of the developed strategy.
