Antibiofilm Activity of Epoxy/Ag-TiO2 Polymer Nanocomposite Coatings against Staphylococcus Aureus and Escherichia Coli (2015)

Dispersion of functional inorganic nano-fillers like TiO2 within polymer matrix is known to impart excellent photobactericidal activity to the composite. Epoxy resin systems with Ag+ ion doped TiO2 can have combination of excellent biocidal characteristics of silver and the photocatalytic properties of TiO2. The inorganic antimicrobial incorporation into an epoxy polymeric matrix was achieved by sonicating laboratory-made nano-scale anatase TiO2 and Ag-TiO2 into the industrial grade epoxy resin. The resulting epoxy composite had ratios of 0.5–2.0 wt% of nano-filler content. The process of dispersion of Ag-TiO2 in the epoxy resin resulted in concomitant in situ synthesis of silver nanoparticles due to photoreduction of Ag+ ion. The composite materials were characterized by DSC and SEM. The glass transition temperature (Tg) increased with the incorporation of the nanofillers over the neat polymer. The materials synthesized were coated on glass petri dish. Anti-biofilm property of coated material due to combined release of biocide, and photocatalytic activity under static conditions in petri dish was evaluated against Staphylococcus aureus ATCC6538 and Escherichia coli K-12 under UV irradiation using a crystal violet binding assay. Prepared composite showed significant inhibition of biofilm development in both the organisms. Our studies indicate that the effective dispersion and optimal release of biocidal agents was responsible for anti-biofilm activity of the surface. The reported thermoset coating materials can be used as bactericidal surfaces either in industrial or healthcare settings to reduce the microbial loads.
Removal of ECG artifacts from EEG using a modified independent component analysis approach (2008)

In this paper, we introduce a new automatic method for electrocardiogram (ECG) artifact elimination from the electroencephalogram (EEG) or the electrooculogram (EOG). It is based on a modification of the independent component analysis (ICA) algorithm which gives promising results while only using a single-channel EEG (or EOG) and the ECG. To check the effectiveness of our approach, we compared its correction rate with those obtained by ensemble average subtraction (EAS) and adaptive filtering (AF). For this purpose, we applied these algorithms to 10 excerpts of polysomnographic sleep recordings containing ECG artifacts and other typical artifacts (e.g. movement, sweat, respiration, etc.). Two hundred successive interference peaks were examined in each excerpt to compute correction rates. We found that our modified ICA was the most robust to various waveforms of cardiac interference and to the presence of others artifacts, with a correction rate of 91.0%, against 83.5% for EAS and 83.1% for AF.
Comprehensive Pharmacokinetic Model of Insulin Glargine and Other Insulin Formulations (2005)

In this paper, a comprehensive pharmacokinetic model for different insulin formulations including insulin Glargine is developed based on the model proposed by Trajanoski et al. (1993). Current models show limitations for insulin Glargine due to the appearance of an uncharacteristic peak in the concentration-time evolution of plasma insulin that does not coincide with real experimental data. This important limitation has been solved in this paper by introducing a new virtual insulin state called the bound state, in addition to the dimeric and hexameric ones. Trying to describe the retarded action of insulin Glargine, the modeling idea behind this approach is that immediately after the subcutaneous injection all the insulin resides in the bound state, and only then small amounts of insulin in the hexameric form disengage from the bound state. For the model evaluation different simulation results are compared. Using experimental data published by Lepore et al. (2000), the developed model turned out to be capable of at least qualitatively predicting the concentration-time profile of plasma insulin. Both exogenous insulin flow simulations and spatial diffusion simulations show the plausibility and correct implementation of the derived model. Considering all these simulation results, the here presented new pharmacokinetic model demonstrates to be able to reproduce real patient behavior simulating even complete insulin regimes including long-acting, intermediate and short-acting insulin formulations.
Using Technology to Teach Parents to Create a Safe Infant Sleep Space (2018)

The American Academy of Pediatrics (AAP) published Recommendations for a Safe Infant Sleeping Environment; however, parents still report frequent use of dangerous infant sleep practices. An online computer program was developed and piloted to investigate whether parents could be taught to create safe sleep environments using online training. Computerized safe sleep environments created by parents of children 0 to 23 months were assessed for compliance with the AAP Sleep Recommendations. Using a pre- and posttest design, the present study investigated the effectiveness of online instructions (adapted standard of care) and a computerized behavioral skills training package, which included instructions, modeling, rehearsal, and feedback. Additional pre- and posttests assessed parents’ ability to identify sleep risks in 3 pictures to assess generalization of skills learned. Overall, participants demonstrated significant improvements from pre- to posttest across both treatment conditions on the creation of a safe sleep environment and on the free response identification of risks in 3 sleep environments. Performance did not significantly differ between the treatment groups. Results suggest considerable promise for technology-aided approaches in training parents to create a safe sleep environment. Implications for Impact Statement Creating safe infant sleep environments is important and necessary in reducing sudden and unexpected infant deaths. In this online study, caregivers created safer infant sleep environments and identified more sleep environment risks after computer-based training and when using a sleep safety checklist. Providing access to this computer-based training and/or sleep safety checklist can teach caregivers about infant sleep safety and may result in safer infant sleep environments.
A forward bias method for lag correction of an a-Si flat panel detector (2011)

Overall, the forward bias method has been found to greatly reduce detector lag ghosts in projection data and the radar artifact in CBCT reconstructions. The method is limited to improvements of the a-Si photodiode response only. A future hybrid mode may overcome any limitations of this method.
Absorption Angstrom Exponent in AERONET and related data as an indicator of aerosol composition (2009)

Abstract. Recent results from diverse air, ground, and laboratory studies using both radiometric and in situ techniques show that the fractions of black carbon, organic matter, and mineral dust in atmospheric aerosols determine the wavelength dependence of absorption (expressed as Absorption Angstrom Exponent, or AAE). Taken together, these results hold promise of improving information on aerosol composition from remote measurements. The purpose of this paper is to show that AAE values for Aerosol Robotic Network (AERONET) retrievals from Sun-sky measurements describing the full aerosol vertical column are also strongly correlated with aerosol composition or type. In particular, we find AAE values near 1 (the theoretical value for black carbon) for AERONET-measured aerosol columns dominated by urban-industrial aerosol, larger AAE values for biomass burning aerosols, and the largest AAE values for Sahara dust aerosols. Ambiguities in aerosol composition or mixtures thereof, resulting from intermediate AAE values, can be reduced via cluster analyses that supplement AAE with other variables, for example Extinction Angstrom Exponent (EAE), which is an indicator of particle size. Together with previous results, these results strengthen prospects for determining aerosol composition from space, for example using the Glory Aerosol Polarimetry Sensor (APS), which promises retrievals of multiwavelength single-scattering albedo (SSA) and aerosol optical depth (and therefore aerosol absorption optical depth (AAOD) and AAE), as well as shape and other aerosol properties. Cluster analyses promise additional information content, for example by using the Ozone Monitoring Instrument (OMI) to add AAOD in the near ultraviolet and CALIPSO aerosol layer heights to reduce height-absorption ambiguity.
Rhodium(I)‐centered cyclotriveratrylene (1995)

Abstract The rigid bowl‐shaped molecule cyclotriveratrylene (CTV, 1 ) was provided with short and long spacer arms terminating in triphenyl phosphite functions. These CTV ligands were used to immobilize a rhodium(I)‐carbonyl‐hydride complex. The ligand with short spacers gave a rigid, strained complex with a trigonal‐coordination sphere around the rhodium. The ligand with long flexible spacers allowed the formation of a large cavity after the complexation to the rhodium center. This cavity, however, is filled up by the spacer arms, as was indicated by NMR studies. Variable‐temperature NMR experiments suggested that the H‐Rh‐CO dipole in the rhodium‐ CTV complex can adopt two orientations: one with the hydride group pointing away from the CTV cavity (low‐temperature conformation) and one in which this orientation is inverted (high‐temperature conformation).
The crystal structure of biuret hydrate (1961)

The hydrate of biuret, NH2CONHCONH2, has a unit cell with space-group C~h-P21/c and a=3.63, b=17.78, c=9.18/~; fl=l19 30' and n = 4. The planar amide groups in biuret have normal dimensions and are slightly inclined and trans to each other, with an internal hydrogen-bond. The biuret molecules lie in buckled sheets parallel to (100), one molecule being joined to each of three neighbours by N-H. O hydrogenbonds.
The prognostic significance of amplification and overexpression of c-met and c-erb B-2 in human gastric carcinomas (2000)

The article by Nakajima et al.1 reports very interesting findings on the putative prognostic meaning of the amplification and overexpression of c-met and c-erb B-2 in patients with gastric carcinoma. The finding of a significant correlation between gene amplification/overexpression of c-erb B-2 with the intestinal type of gastric carcinoma corresponds with our own results on the same topic.2 In our hands, like in the study by Nakajima et al., c-met amplification/overexpression tends to be higher in diffuse carcinoma whereas c-erb B-2 amplification/overexpression is restricted almost exclusively to intestinal type carcinoma.2, 3 The data from Nakajima et al.1 also demonstrate the advantage of the classification of Laurén over the World Health Organization (WHO) classification because Laurén's classification divides gastric carcinoma into two major types with epidemiologic and histogenetic meaning. The separation of gastric carcinoma into these two main types also contributes to clarification of the problem of grading because the majority of the so-called poorly differentiated carcinomas fit into the category of intestinal carcinoma (and often display c-erb B-2 amplification/overexpression) rather than into the category of diffuse carcinoma. This option is reinforced by the finding of a close correlation between E-cadherin mutation and diffuse carcinoma,4 both in pure histologic types as well as in mixed carcinoma. In the latter, E-cadherin mutations are found in the isolated cell component and not in the glandular counterpart.4 With regard to prognosis our data also fit with those of Nakajima et al.1 by showing the prominence of staging5, 6 and the lack of relative importance of histologic classification whenever the Laurén or WHO classifications are used.5 The same does not hold true when the tumors are classified into four major categories: glandular, isolated cell type, mixed, and solid.5 This classification was found to carry independent prognostic value in multivariate analysis mainly due to the dismal outcome of patients with mixed carcinomas.5 It would be interesting to know whether, in the series by Nakajima et al.,1 c-met and c-erb B-2 amplification/overexpression differs, like E-cadherin mutations, in the two components of mixed carcinomas. It also would be interesting to learn if such mixed carcinomas in the series by Nakajima et al. carry a worse prognosis than pure histologic types, as they did in our study.

Interaction Methods for Smart Glasses (2017)

Since the launch of Google Glass in 2014, smart glasses have mainly been designed to support micro-interactions. The ultimate goal for them to become an augmented reality interface has not yet been attained due to an encumbrance of controls. Augmented reality involves superimposing interactive computer graphics images onto physical objects in the real world. This survey reviews current research issues in the area of human computer interaction for smart glasses. The survey first studies the smart glasses available in the market and afterwards investigates the interaction methods proposed in the wide body of literature. The interaction methods can be classified into hand-held, touch, and touchless input. This paper mainly focuses on the touch and touchless input. Touch input can be further divided into on-device and on-body, while touchless input can be classified into hands-free and freehand. Next, we summarize the existing research efforts and trends, in which touch and touchless input are evaluated by a total of eight interaction goals. Finally, we discuss several key design challenges and the possibility of multi-modal input for smart glasses.
The renaissance of 2,4,6-tris(2-pyrimidyl)-1,3,5-triazine (TPymT) coordination chemistry (2015)

In this perspective we report on recently accumulated data on the synthesis and coordination chemistry of 2,4,6-tris(2-pyrimidyl)-1,3,5-triazine (TPymT). Although a highly attractive ligand, owing to the presence of three fused terpyridine-like coordination pockets, the coordination chemistry of TPymT has something of a chequered past. This can principally be attributed to the hydrolysis of the ligand, which readily occurs under mild conditions. Thus, after first being synthesised in 1959 it had only been used a handful of times to synthesise coordination compounds until we began reinvestigating its chemistry in early 2013. Despite the significant challenges associated with its use, our work over the past two years has demonstrated that coordination chemistry with TPymT is indeed possible. Herein, we describe an overview of this body of work as it stands, and discuss its potential impact in a variety of areas including porous materials, catalysis and crystal engineering.
Experimental investigation and measurement of the bearing current in a multilevel inverter-fed induction motor drive (2011)

The development of Space Vector Modulation (SVM) based AC adjustable speed drives (ASD's) has increased the inverter output AC voltage, performance, efficiency, and controllability in speed controlled induction motor applications. However due to fast switching of the MOSFETs/IGBT's, introduces the high frequency transients at the output of the inverter. In addition, due to non-sinusoidal voltage output at the inverter, there exists the voltage at the star point of the Induction Motor (IM) with respect to the common ground (gnd). Due to this, the rotor shaft voltage is induced, resulting in bearing current which is harmful to the bearing. The grease film in the bearing acts as a capacitor and due to the voltage transitions in the star point of the stator winding it gets charged. The breakdown of the film causes transient current that induces electrical discharge machining (EDM) and due to that pitting occurs in the inner surface of the bearing, thereby reducing the bearing life. Significant efforts were made by the researchers in this direction to minimize the problem. This paper presents the experimental investigation and measurement of bearing current for the modified 3-phase squirrel cage IM connected to a 3-level SVM based inverter bridge circuit. PIC Microcontroller and other associated electronic interface circuits control the inverter bridge circuit. Standard current probe, LISN and a high frequency 4-channel Mixed Signal Oscilloscope (MSO) and digital storage oscilloscope (DSO) with differential probes were used to measure the bearing current in terms of voltage from the current probe and other parameters. For comparing the results with Federal Communications Commission (FCC) and Special Committee on Radio Interference (CISPR) standards the graphs are plotted with Frequency vs dBμV and the bearing current in dBμA for the 3-level inverter (SVM method) using signal analysis software. For conclusion the SVM method results are compared with SPWM method published results.
Ab Initio Evaluation of Uranium Carbide <em>S(α,β)</em> and Thermal Neutron Cross Sections (2022)

Uranium Carbide (UC) is a nuclear fuel material which offers better neutron economy and lower fuel-cycle costs compared to conventional mixed-oxide fuels. UC’s lattice binding and dynamical properties impact thermal neutron scattering and low temperature epithermal resonance absorption. The Thermal Scattering Law (TSL) describes the scattering system available energy and momentum transfer states. There is no TSL evaluation for UC in the ENDF/B-VIII.0 database; herein, &lt;em&gt;ab-initio&lt;/em&gt; lattice dynamics (AILD) techniques are invoked to calculate the phonon spectrum for UC using spin-orbit-coupling density functional theory (DFT). The TSLs, inelastic and elastic thermal scattering cross sections for Uranium and Carbon in UC, respectively, are calculated in &lt;em&gt;FLASSH&lt;/em&gt; for use in higher fidelity reactor design calculations.
Communication Complexity of Approximate Matching in Distributed Graphs (2015)

In this paper we consider the communication complexity of approximation algorithms for maximum matching in a graph in the message-passing model of distributed computation. The input graph consists of n vertices and edges partitioned over a set of k sites. The output is an \alpha-approximate maximum matching in the input graph which has to be reported by one of the sites. We show a lower bound on the communication complexity of \Omega(\alpha^2 k n) and show that it is tight up to poly-logarithmic factors. This lower bound also applies to other combinatorial problems on graphs in the message-passing computation model, including max-flow and graph sparsification.
Detection of liquid H2O in vapor bubbles in reheated melt inclusions: Implications for magmatic fluid composition and volatile budgets of magmas? (2016)

Fluids exsolved from mafic melts are thought to be dominantly CO2-H2O S fluids. Curiously, although CO2 vapor occurs in bubbles of mafic melt inclusions (MI) at room temperature (7), the expected accompanying vapor and liquid H2O have not been found. We reheated olivine-hosted MI from Mt. Somma-Vesuvius, Italy, and quenched the MI to a bubble-bearing glassy state. Using Raman spectroscopy, we show that the volatiles exsolved after quenching include liquid H2O at room T and vapor H2O at 150 degrees C. We hypothesize that H2O initially present in the MI bubbles was lost to adjacent glass during local, sub-micrometer-scale devitrification prior to sample collection. During MI heating experiments, the H2O is redissolved into the vapor in the bubble, where it remains after quenching, at least on the relatively short time scales of our observations. These results indicate that (1) a significant amount of H2O may be stored in the vapor bubble of bubble-bearing MI and (2) the composition of magmatic fluids directly exsolving from mafic melts at Mt. Somma-Vesuvius may contain up to 29 wt% H2O

Detection of quantum-dot labelled proteins using soft glass microstructured optical fibers (2007)

The detection of quantum-dot labeled proteins is demonstrated within lead silicate soft glass microstructured optical fibers using near infrared light. The protein concentration is measured using a new fluorescence capture approach. Light guided within the fiber is used both to excite and collect fluorescent photons, and the detection limit achieved without optimization of the fiber geometry is 1 nM, using just 3% of the guided mode of the fiber. Issues that currently restrict the detection of lower protein concentrations are discussed.
