Guidelines for writing good asphalt related research papers (2013)

Review of numerous asphalt related technical papers published in India has revealed that their quality is generally not up to international standards. This paper gives guidelines for improving the quality of research papers on asphalt technology. Comprehensive guidelines have been given for various typical sections generally contained in research papers, such as abstract, introduction, scope of study and objectives, review of literature, materials, testing procedures and experiment plan, construction data (if any), test data and statistical analyses, conclusions and recommendations, acknowledgments, references, and appendices. Many of the guidelines are also applicable and useful for research papers on other areas of transportation.
On Delay Sensitivity Clusters of Microgrid Data Aggregation Under LTE-A Links (2021)

Accurate analysis and classification of delay sensitivity of the data sent from smart meters is a two-fold challenging problem which contains analytics and network latency dimensions. In the case of resilient community microgrids, vitality of the energy consumption and power usage data is further evident so to make proactive decisions to entail smooth transitions between islanded and non-islanded modes of the microgrids. In light of these, this paper analyzes smart microgrid data aggregation against time intervals to determine the delay sensitivity of aggregated messages sent over microgrid networks via LTE and LTE+links. To meet the latency requirements, we propose a Time of Use (ToU)-aware and unsupervised learning-backed microgrid data aggregation scheme to cluster the message of the same delay sensitivity and prioritize bursts with respect to delay sensitivity to achieve low delay overhead for high and moderately delay sensitive messages. Through simulations, we have shown that by using ToU-aware model, microgrids can prioritize 247% more critical consumption requests in order to keep stable operations during islanded mode.
Ultrafast Optical Microscopy of Single Monolayer Molybdenum Disulfide Flakes (2016)

We have performed ultrafast optical microscopy on single flakes of atomically thin CVD-grown molybdenum disulfide, using non-degenerate femtosecond pump-probe spectroscopy to excite and probe carriers above and below the indirect and direct band gaps. These measurements reveal the influence of layer thickness on carrier dynamics when probing near the band gap. Furthermore, fluence-dependent measurements indicate that carrier relaxation is primarily influenced by surface-related defect and trap states after above-bandgap photoexcitation. The ability to probe femtosecond carrier dynamics in individual flakes can thus give much insight into light-matter interactions in these two-dimensional nanosystems.
Effects of acid treatments on physical properties of carbon nanotube (CNT) wires for wiring applications (2020)

Carbon nanotube (CNT) wires are mechanically stronger and extremely lightweight nanomaterials with highly efficient mechanical, thermal and electrical properties compared to the conventional materials. The new applications of these superior nanomaterials include aircraft, energy, biomedical, sensor, defense, electronics and space. One very interesting potential application of carbon nanotubes is in electrical wiring. Conventional electrical wires made of copper and aluminum suffer from several problems including weight (an issue in aerospace applications), skin effect (hindering their use in modern telecommunications), mechanical performance (critical in overhead power lines and ductility), and electromigration (severely damaging microscopic wires in electronics applications). Moreover, the growing demand for these conventional metal conductors and the continually increasing prices suggests that a low-cost material that can outperform conventional conductors would be highly desirable. Hence, carbon nanotubes are the material of great interest for those. In the study, CNT wires were immersed into the acid bath under ambient conditions for different time periods to analyze their physical property changes. Chemical treatment drastically changed the physical dimensions of the CNT wire, including increase in diameter and a decrease in length. Also, chemical bonds were created between the CNTs, which might increase the properties of the CNT wires. Under tensile load, chemical treatment has been proven to slightly increase the tensile strength and conductivity of the CNT wires, but the test results were scattered substantially. This study may create new possibilities to enhance the physical and chemical properties of CNT wires in a number of different industrial applications.

Mechanical and electrical properties of mesoporous MCM-41/unsaturated polyester in situ composites (2015)

AbstractAbstractIn this study, mesoporous materials-41 were synthesised at room temperature using a cationic surfactant cetyltrimethylammonium bromide as the template agent. Then, the mesoporous materials-41/unsaturated polyester resin materials were prepared by in situ polymerisation with the mesoporous MCM-41. Then, mesoporous materials-41/unsaturated polyester resin in situ composites were prepared by roller, milling and molding processes. The effects of the mesoporous materials-41 on the mechanical and electrical properties of the mesoporous materials-41/unsaturated polyester resin composites were investigated. The results show that the mesoporous materials-41 had a diameter in the range of 4–5 nm and the pores were highly ordered. The mechanical and electrical insulation properties of composites were improved by the addition of mesoporous materials-41. For instance, the impact strength and flexural strength of composites were increased by 29·6 and 25·25% at 2 wt-% mesoporous materials-41 loading, respectively.Keywords: Mesoporous materialsUnsaturated polyesterIn situ polymerisationInorganic–organic–compositeMechanical propertiesElectrical properties AcknowledgementsThe authors would like to acknowledge the National Natural Science Foundation of China (Grant No.: 51263005, 51163003, 51203029, 21264005), Guangxi Natural Science Foundation of China (Grant No.: 2013GXNSFDA019008, 2014GXNSFAA118321), Guangxi Small Highland Innovation Team of Talents in Colleges and Universities, and Innovation Team of Guangxi Universities' Talent Highland for financial support.

Chromosomal aberrations in human neuroblastomas (1977)

Six human neuroblastomas were analyzed by Giemsa and fluorescence banding techniques to identify chromosomal aberrations. Two neuroblastomas were primary tumors from untreated children, and four were well lines established from human neuroblastomas. Five of the six tumors studied were diploid or near diploid; one was near tetraploid. A 1p- was found in three of the neuroblastomas examined. The 1p-was present in both primary tumors, and in one it was the only abnormality detected. This deletion was also found in the cells of an established line, in addition to other abnormalities. Giant markers of different origins were found in the four cell lines, and no double-minute chromosomes were found in the primaries or the cell lines studied. Thus, a 1p-deletion was the most consistent abnormality found in the six human neuroblastomas examined in this study. We attempt to correlate this finding with Knudson's hypothesis on the origin of childhood cancer. Additional studies of primary tumors should clarify whether this specific chromosomal abnormality is related to the the acquisition of malignant behavior in human neuroblastomas.
Hydrogen-Water Flow Regime Transitions Applied to Anode Flow Phenomena in a PEMFC (2005)

Although water is produced on the cathode side of a polymer electrolyte membrane fuel cell (PEMFC), it is known to migrate to the anode, where the two-phase hydrogen-water interactions become critical to keep the channels clear for effective reactant delivery. Hydrogen-water flow regime transitions were experimentally investigated and compared to air-water transitions in a 1.0 mm square channel. Gas superficial velocities were evaluated for an anode stoichiometric ratio of 2.0 over a current density range from 0.1 A/cm2 to 2.0 A/cm2 . Liquid superficial velocities were controlled at the corresponding cathodic water production rate. It is shown that the annular transition in a hydrogen system occurs at as much as twice the gas velocity required for the same transition in an air system. At the low liquid flux expected in the anode channels of a PEMFC, a transition from slug to annular two-phase flow will occur at an unobtainable velocity for efficient fuel cell operation.© 2005 ASME
Development of a Cell-Based Fluorescence Polarization Biosensor Using Preproinsulin to Identify Compounds That Alter Insulin Granule Dynamics (2020)

Diabetes currently affects 9.3% of the U.S. population totaling $245 billion annually in U.S. direct and indirect healthcare costs. Current therapies for diabetes are limited in their ability to control blood glucose and/or enhance insulin sensitivity. Therefore, innovative and efficacious therapies for diabetes are urgently needed. Herein we describe a fluorescent insulin reporter system (preproinsulin-mCherry, PPI-mCherry) that tracks live-cell insulin dynamics and secretion in pancreatic β-cells with utility for high-content assessment of real-time insulin dynamics. Additionally, we report a new modality for sensing insulin granule packaging in conventional high-throughput screening (HTS), using a hybrid cell-based fluorescence polarization (FP)/internal FRET biosensor using the PPI-mCherry reporter system. We observed that bafilomycin, a vacuolar H+ ATPase inhibitor and inhibitor of insulin granule formation, significantly increased mCherry FP in INS-1 cells with PPI-mCherry. Partial least squares regression analysis demonstrated that an increase of FP by bafilomycin is significantly correlated with a decrease in granularity of PPI-mCherry signal in the cells. The increased FP by bafilomycin is due to inhibition of self-Förster resonant energy transfer (homo-FRET) caused by the increased mCherry intermolecular distance. FP substantially decreases when insulin is tightly packaged in the granules, and the homo-FRET decreases when insulin granule packaging is inhibited, resulting in increased FP. We performed pilot HTS of 1782 FDA-approved small molecules and natural products from Prestwick and Enzo chemical libraries resulting in an overall Z′-factor of 0.52 ± 0.03, indicating the suitability of this biosensor for HTS. This novel biosensor enables live-cell assessment of protein–protein interaction/protein aggregation in live cells and is compatible with conventional FP plate readers.
MRI‐measured water mobility increases in response to chemotherapy via multiple cell‐death mechanisms (2007)

Numerous pre-clinical and clinical reports have demonstrated that the MRI-measured apparent diffusion coefficient of water (ADC) increases early in the response to a wide variety of anti-cancer therapies. It has been proposed that this increase in ADC generally results from an increase in the tumor extracellular volume fraction leading to a greater degree of unrestricted water motion. Furthermore, an increase in extracellular volume has been ascribed to the cell shrinkage that occurs early in the process of programmed cell death. However, other modes of death can be initiated soon after beginning therapy. These other modes of death include mitotic catastrophe and necrosis, and may also involve changes in the fraction of water with unrestricted motion. This work examines whether MRI-measured ADC is altered in response to therapies that induce cell death via non-apoptotic mechanisms and correlates ADC changes with cell death modalities regionally within the tumor. Apoptotic responses were limited to the tumor periphery in apoptosis-proficient tumors. Apoptosis was not observed in deficient tumors. Mitotic catastrophe was observed after treatment at the periphery and deeper into the tumor. Necrosis was the predominant response in the center of the tumor. ADC changes were moderate in the periphery and larger in the center. The results indicate that early and significant changes in ADC can occur in concert with mitotic catastrophe and lytic necrosis in the absence of apoptosis. Hence, changes in ADC may be a generalized measure of cytotoxic response to chemotherapy.
Data on metabolic profiling of spongy tissue disorder in Mangifera indica cv. Alphonso (2018)

Data in this article presents aroma volatiles and fatty acids composition of mesocarp specific malady namely spongy tissue disorder in <i>Mangifera indica</i> cv. Alphonso. Quantitative changes in various aroma volatile compound classes as well as saturated and unsaturated fatty acids in spongy tissue vis-à-vis healthy mesocarp have been analyzed throughout the development of the disorder. Statistical data analysis correlates the dynamic changes in the aroma volatiles composition to that of the modulation in the fatty acids profile.
Conjugated Polymers: Evaluating DFT Methods for More Accurate Orbital Energy Modeling (2013)

Density functional theory (DFT) calculations are useful to model orbital energies of conjugated polymers, yet discrepancy between theory and experiment exist. Here we evaluate a series of relatively straightforward calculation methods using the standard Gaussian 09 software package. Five calculations were performed on 22 different conjugated polymer model compounds at the B3LYP and CAM-B3LYP levels of theory and results compared with experiment. Chain length saturation occurs at approximately 6 and 4 repeat units for homo- and donor–acceptor type conjugated polymers, respectively. The frontier orbital energies are better approximated using B3LYP than CAM-B3LYP, and the HOMO energy can be reasonably correlated with experiment [mean signed error (MSE) = 0.22 eV]. The LUMO energies, however are poorly correlated (MSE = 0.59 eV), and we show that the molecular orbital energy of the triplet state gives a much better estimate of the experimentally determined LUMO level (MSE = −0.13 eV).
Scanning tunneling microscopy studies of sulfur overlayers on the Re(0001) surface (1991)

The structure of sulfur adsorbed on the basal plane of rhenium has been studied in ultrahigh vacuum with Auger, low-energy electron diffraction, and scanning tunneling microscopy. At low coverages (&amp;lt;0.25 monolayers) single sulfur adatoms form open structures with p(2×2) and c( 7/8 ×5) rectangular lattices. In these structures both the sulfur adatoms and some of the rhenium substrate atoms are imaged simultaneously, identifying the sulfur adsorption site as a threefold hollow site. At coverages above 0.25 ML sulfur adatoms aggregate into trimers, first disordered and then ordered into a (3 7/8 ×3 7/8 )R30° lattice at a coverage of 0.45 ML. Two types of trimers form that are centered around different substrate sites. Between 0.45 and 0.5 ML diamond-shaped sulfur tetramers appear until an ordered (3113) structure forms. With further exposure to H2S a final structure is formed, consisting of hexagonal sulfur rings in a (2 7/8 ×2 7/8 )R30° lattice. All of the sulfur adatoms in the three high coverage structures occupy the same type of threefold hollow sites as in the low coverage structures.

Predictive scheduling for Electric Vehicles considering uncertainty of load and user behaviors (2016)

Un-coordinated Electric Vehicle (EV) charging can create unexpected load in local distribution grid, which may degrade the power quality and system reliability. The uncertainty of EV load, user behaviors and other baseload in distribution grid, is one of challenges that impedes optimal control for EV charging problem. Previous researches did not fully solve this problem due to lack of real-world EV charging data and proper stochastic model to describe these behaviors. In this paper, we propose a new predictive EV scheduling algorithm (PESA) inspired by Model Predictive Control (MPC), which includes a dynamic load estimation module and a predictive optimization module. The user-related EV load and base load are dynamically estimated based on the historical data. At each time interval, the predictive optimization program will be computed for optimal schedules given the estimated parameters. Only the first element from the algorithm outputs will be implemented according to MPC paradigm. Current-multiplexing function in each Electric Vehicle Supply Equipment (EVSE) is considered and accordingly a virtual load is modeled to handle the uncertainties of future EV energy demands. This system is validated by the real-world EV charging data collected on UCLA campus and the experimental results indicate that our proposed model not only reduces load variation up to 40% but also maintains a high level of robustness. Finally, IEC 61850 standard is utilized to standardize the data models involved, which brings significance to more reliable and large-scale implementation.
Improved Luminescence of Lanthanide(III)-Doped Nanophosphors by Linear Aggregation (2007)

The studies and applications of nanophosphors are considerably important, but unfortunately, their luminescence is always rather poor. Here, we report that the oriented aggregation of nanophosphors can significantly enhance their luminescent emissions at the nanoscale. LnPO4 (Ln = La, Ce, and Tb) is extensively used in luminescent lighting industry, but the total quantum yield of synthesized individual ∼20 nm La0.60Ce0.26Tb0.14PO4 particles is only ∼21%. This value is improved up to ∼80% when five to seven of these nanophosphors are linearly aggregated to form an oriented structure. The luminescence intensities of these linear aggregates of nanophosphors increase correspondingly. It is suggested that one-dimensional nanoaggregation plays an essential role in this luminescence improvement, which might be a useful strategy in the application of nanophosphors.

Impact of Tocilizumab (Anti–IL-6R) Treatment on Immunoglobulins and Anti-HLA Antibodies in Kidney Transplant Patients With Chronic Antibody-mediated Rejection (2019)

TCZ reduced total IgG and IgG1-3 and anti-HLA-total IgG and IgG3 levels, suggesting that TCZ suppresses Ig production in B cells nonspecifically, likely through inhibition of interleukin 6-mediated signaling to B cells and plasma cells. This may be a contributing factor for the beneficial effect of TCZ on cAMR observed in this patient population.
Development and suitability of Indian languages speech database for building watson based ASR system (2013)

In this paper, we discuss our efforts in the development of Indian spoken languages corpora for building large vocabulary speech recognition systems using WATSON Toolkit. The current paper demonstrates that these corpora can be reduced to a varied degree for various phonemes by comparing the similarity among phonemes of different languages. We also discuss the design and methodology of collection of speech databases and the challenges we have faced during database creation. The experiments have been conducted on commonly known Indian languages, by training the ASR system with WATSON toolkit and evaluation by Sclite. The results for these experiments show that different Indian languages have a great similarity among their phoneme structures and phoneme sequences and we have exploited these features to create speech recognition system. Also, we have developed an algorithm to bootstrapping the phonemes of one particular language into another by mapping the phonemes of different languages. The performance of Hindi and Bangla ASR systems using these databases has been compared.
Induction of Oxidative DNA Damage by Flavonoids of Propolis: Its Mechanism and Implication about Antioxidant Capacity (2011)

Propolis from beehives is commonly used as a home remedy for various purposes including as a topical antiseptic. Despite its antioxidant capacity, propolis induces oxidative DNA damage. In exploring the underlying mechanism, we found that the induction of oxidative DNA damage is attributed to the hydrogen peroxide (H(2)O(2)) produced by propolis. The formation of H(2)O(2) can take place without the participation of cells but requires the presence of transition metal ions such as iron. Flavonoids such as galangin, chrysin, and pinocembrin that are commonly detected in propolis have the capacity to induce oxidative DNA damage, and that capacity correlates with the production of H(2)O(2), suggesting the involvement of flavonoids in propolis in this process. On the basis of these results, we propose that the flavonoids of propolis serve as temporary carriers of electrons received from transition metal ions that are relayed to oxygen molecules to subsequently generate superoxide and H(2)O(2). In addition, propolis induces oxidative DNA damage that is subject to repair, and propolis-treated cells show a lower level of DNA damage level when challenged with another oxidative agent such as amoxicillin. This is reminiscent of an adaptive response that might contribute to the beneficial effects of propolis.
Abnormal expression of hepatoma specific ?-glutamyl transferase and alteration of ?-glutamyl transferase gene methylation status in patients with hepatocellular carcinoma (2000)

The abnormal alteration of serum HS-GGT level is a sensitive tumor marker for HCC diagnosis or differentiation, and the overexpression of GGT in HCC may be related to the hypomethylational status of CCGG sites of GGT genes.
A Time-Variant Wideband Spatial Channel Model Based on the 3GPP Model (2006)

In this paper, the short-term time variation of wideband channels is investigated based on some extensions to the interim beyond-3G (IB3G) spatial channel model (SCM), which was developed for a multi-input multi-output (MIMO) system and used within the European WINNER project. These extensions mainly include some modifications of the generation of the wideband fast fading channel matrix, such as the consideration of the time variant sub-path phases at the mobile station (MS), the consideration of the powers of the time variant multi-paths, and the generation of different last bounce distances (LBDs) for the mid-paths within each path. In order to measure the short-term time variation of the wideband channels, this paper redefines the correlation matrix distance (CMD) metric, which was originally for the narrowband fast fading scenario. The simulated CMD generated from the newly extended Third Generation Partnership Project (NE-3GPP) spatial channel model (SCM) compares better to the measurements taken in the FLOWS project than that of the IB3G SCM.
