Morphology and Crystallization Behavior of HDPE/CNT Nanocomposite (2006)

Polymer carbon nanotube nanocomposites (PCNs) represent the first realized major commercial application of carbon nanotubes (CNTs). In this study, high density polyethylene (HDPE)/CNT PCNs have been prepared using a solution blending technique. Both pristine single‐walled nanotubes (SWNT) and polyethylene (PE) single crystal decorated CNTs (so called nano hybrid shish kebabs, NHSKs) have been used as the precursors for PCN preparation. Polarized light microscopy, transmission electron microscopy, scanning electron microscopy, differential scanning calorimetry, and thermogravimetry were used to study the morphology, crystallization behavior, and thermal stability of the resulting PCNs. The PCNs from pristine SWNTs possess a more dense morphology than do the PCNs prepared from NHSKs; PE single crystal lamellae are perpendicular or oblique to the CNT axis, leading to relatively “open‐structured” PCNs. Heterogeneous nucleation occurred in both nonisothermal and isothermal crystallization of PCNs and the crystallization kinetics are much faster than that of the pure HDPE. Thermal stability of PCNs showed dramatic enhancement (as high as 70°C/115°C improvement of T max in N2/air atmosphere, respectively), which is attributed to the formation of the free radical scavenging CNT network.
Strain identification of Mycobacterium tuberculosis by DNA fingerprinting: recommendations for a standardized methodology (1993)

DNA fingerprinting of Mycobacterium tuberculosis has been shown to be a powerful epidemiologic tool. We propose a standardized technique which exploits variability in both the number and genomic position of IS6110 to generate strain-specific patterns. General use of this technique will permit comparison of results between different laboratories. Such comparisons will facilitate investigations into the international transmission of tuberculosis and may identify specific strains with unique properties such as high infectivity, virulence, or drug resistance.
[Use of electrocardiographic placement control of central venous catheters in Austria]. (1999)

After placement of a central venous catheter the correct position of the catheter tip has to be verified. The use of intravascular ECG tracing via a guide-wire or via the saline-filled lumen of the catheter enables immediate and safe control of the position. Only if complications (e.g. pneumothorax) are suspected, further clinical and radiological diagnostics are necessary. Up to now, no data on the routine clinical use of this method are available. In April 1998, a semi-structured questionnaire was sent to the 518 heads of anaesthesiological, surgical and medical departments in Austria (33% of the questionnaires were returned). The subclavian (56%) and internal jugular veins (35%) are most frequently used for catheter insertion in Austria. Verification of the catheter tip placement by ECG-guidance is used in only 8% of cases, while radiographs are performed in most cases. Uncertainty with respect to forensic consequences of using the ECG-guidance for control of the catheter tip placement and the possible necessity of an additional radiograph are the main problems seen by the heads of the departments. After placement of a central venous line, measures for the verification of the catheter tip and measures for the control of possible complications have to be considered separately. Intravascular ECG tracing is unable to detect complications. Concerning the verification of the catheter tip position many studies confirm the easy handling, relevance of results and cost savings for this method. Its use for the control and documentation of the tip location is considered a standard. In Austria the consequent use of the method would offer the chance for significant reductions of treatment costs.
Spectral deconvolution for overlapping GC/MS components (1992)

The use of mass chromatogram peak centroids has been investigated as a means of deconvoluting the spectra of overlapping gas chromatography/mass spectrometry components. The peak centroids have been calculated with a precision of 0.04 scans (sd). This proved sufficient to allow deconvolution of the mass spectra belonging to two chemical components which were eluted 0.48 scans apart. For a more complex chromatography peak, it was possible to deconvolute the spectra of six components which were eluted within a 9 scan window. All the spectra produced by using this deconvolution mechanism agreed well with National Institute of Standards and Technology database spectra.
Aged Garlic Extract with Supplement is Associated with Beneficial Effect on Bone Mineral Density and Predicts Lack of Progression of Atherosclerosis: A Prospective Double Blinded Randomized Trial (2015)

Aged Garlic Extract with Supplement is Associated with Beneficial Effect on Bone Mineral Density and Predicts Lack of Progression of Atherosclerosis: A Prospective Double Blinded Randomized Trial Low levels of bone-mineral-density (BMD) are independently associated with the presence and severity of coronary-arterycalcium (CAC). This study evaluates the beneficial-effects of aged-garlic-extract therapy with-supplements (AGE-S) on levels of BMD, vascular-function, inflammation and CAC. Sixty subjects, randomized to four daily capsules of placebo vs. AGE-S inclusive of aged garlic extract (1000 mg) plus VitaminB12 (400 mcg or µg), folic-acid (1200 mcg or µg), Vitamin-B6 (50 mg) and L-arginine (400 mg) underwent CAC, thoracicBMD (mg/cc), lipid-profile, lipoprotein a (Lp-a), homocysteine and vascular-function measurement at baseline and 12- months. The postcuff-deflation temperature-rebound (TR), digital-thermal-monitoring index of vascular-function was assessed using a reactive-hyperemia-procedure. At 1-year, the mean increase in CAC and decrease in BMD was significantly lower in the AGE-S as compared to the placebo (p<0.05). After adjustment for risk-factors, the risk of CAC progression and reduced BMD was 65% and 68% less in AGE-S as compared to placebo (P<0.05). From baseline to 12 months, a significant correlation was noted between increase in CAC and decreases in BMD. Similarly, a significant correlation was noted between increase in TR and decrease in homocysteine as well as increase in Lp-a with lack of decrease in BMD. The maximum beneficial effect of AGE-S was noted with increase in TR, lack of decrease in BMD and lack of progression of CAC. In conclusion, this study demonstrates AGE-S is independently associated with favorable effect on A strong direct relation between increases in vascular-function, decrease in inflammation with lack of lowering in BMD levels as well as lack of CAC-progression in response to AGE-S was noted.
Non-linear temperature dependence of nitrogen adsorption and decomposition on Fe(111) surface (2023)

The cleavage of the N2 triple bond on the Fe(111) surface is believed to be the rate limiting step of the famed Haber-Bosch ammonia catalysis. Using a combination of machine learning potentials and advanced simulation techniques, we study this important catalytic step as a function of temperature. We find that at low temperatures our results agree with the well-established picture. However, if we increase the temperature to reach operando conditions the surface undergoes a global dynamical change and the step structure of the Fe(111) surface is destroyed. The catalytic sites, traditionally associated with the Fe(111) surface appear and disappear continuously. Our simulations illuminate the danger of extrapolating low-temperature results to operando conditions and indicate that the catalytic activity can only be inferred from calculations that take dynamics fully into account. More than that, they show that it is the transition to this highly fluctuating interfacial environment that drives the catalytic process.
Direct Observation of Heat Transport in Plural AlN Films Using Thermal Imaging and Transient Thermal Reflectance Method (2011)

Transient thermal reflectance and thermal imaging were used to examine heat transport through AlN thin films deposited on Si substrates. The effective thermal conductivity of thin-film AlN was found to be in the range of 2–7 W/mK, depending on the microstructure of the film. Experimental thermal imaging comparisons also indicate a 32% higher heat dissipation efficiency for AlN films compared with SiO2 films of similar thickness.
Mini-Review on Lipofuscin and Aging: Focusing on The Molecular Interface, The Biological Recycling Mechanism, Oxidative Stress, and The Gut-Brain Axis Functionality (2020)

Intra-lysosomal accumulation of the autofluorescent "residue" known as lipofuscin, which is found within postmitotic cells, remains controversial. Although it was considered a harmless hallmark of aging, its presence is detrimental as it continually accumulates. The latest evidence highlighted that lipofuscin strongly correlates with the excessive production of reactive oxygen species; however, despite this, lipofuscin cannot be removed by the biological recycling mechanisms. The antagonistic effects exerted at the DNA level culminate in a dysregulation of the cell cycle, by inducing a loss of the entire internal environment and abnormal gene(s) expression. Additionally, it appears that a crucial role in the production of reactive oxygen species can be attributed to gut microbiota, due to their ability to shape our behavior and neurodevelopment through their maintenance of the central nervous system.
Time‐series transcriptional profiling yields new perspectives on susceptibility to murine osteoarthritis (2012)

This study is the first to show that AC chondrocytes share a high-abundance gene-expression program with skeletal muscle. We show that failure to switch this program off, as well as the restoration of this program, is associated with inappropriate expression of NF-κB signaling pathways, skeletal muscle-related genes, and induction and/or progression of OA.

On the two modes of operation of monolithic Ag-C brushes (1989)

The previously observed transition from low-temperature (mode I) to high-temperature (mode II) behavior in silver-graphite brushes can be explained either by changes of constriction resistance through the temperature dependence of electrical resistivity and hardness at negligible film resistivity and one to three contact spots, or by loss of graphite lubrication within the interfacial film. These two interpretations were tested by controlling the contact spot temperature: (1) by heating in an oven and (2) by local heat input through friction. Correlated studies of contact resistance, friction, wear rate, wear chip size, wear chip microstructure, and calculations of contact spot temperatures favor the second hypothesis. Micrographic evidence suggests that this occurs through desorption of water vapor from the graphite. It is found that primary wear particles form due to the wedge mechanism and by cutting by graphite fragments steeply inclined to the interface. Silver fragments may consolidate into secondary wear particles.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Studies on lithium-sulfur dioxide (Li/SO) battery safety hazards (1983)

The chemistry and thermal behavior of Li/SO/sub 2/ cells have been investigated under conditions of discharge, storage and/or overdischarge. In situ spectroelectrochemical studies have been carried out on anode limited cells at room temperature and at -22/sup 0/C. Accelerating Rate Calorimetry has been used to study Li/SO/sub 2/ cells during and following overdischarge. Lithium-limited cells are shown to be intrinsically safe while cells containing excess lithium have been shown to be capable of undergoing thermal runaway. Proposed reactions responsible for thermal runaway are those of lithium with acetonitrile, electrolyte and/or lithium dithionite and the thermal decomposition of lithium dithionite. Li/SO/sub 2/ cells overdischarged at low temperature pose thermally hazardous conditions.

Molecular basis of bacterial resistance to chloramphenicol and florfenicol (2004)

Chloramphenicol (Cm) and its fluorinated derivative florfenicol (Ff) represent highly potent inhibitors of bacterial protein biosynthesis. As a consequence of the use of Cm in human and veterinary medicine, bacterial pathogens of various species and genera have developed and/or acquired Cm resistance. Ff is solely used in veterinary medicine and has been introduced into clinical use in the mid-1990s. Of the Cm resistance genes known to date, only a small number also mediates resistance to Ff. In this review, we present an overview of the different mechanisms responsible for resistance to Cm and Ff with particular focus on the two different types of chloramphenicol acetyltransferases (CATs), specific exporters and multidrug transporters. Phylogenetic trees of the different CAT proteins and exporter proteins were constructed on the basis of a multisequence alignment. Moreover, information is provided on the mobile genetic elements carrying Cm or Cm/Ff resistance genes to provide a basis for the understanding of the distribution and the spread of Cm resistance--even in the absence of a selective pressure imposed by the use of Cm or Ff.
Sox2 promotes tamoxifen resistance in breast cancer cells (2013)

Development of resistance to therapy continues to be a serious clinical problem in breast cancer management. Cancer stem/progenitor cells have been shown to play roles in resistance to chemo‐ and radiotherapy. Here, we examined their role in the development of resistance to the oestrogen receptor antagonist tamoxifen. Tamoxifen‐resistant cells were enriched for stem/progenitors and expressed high levels of the stem cell marker Sox2. Silencing of the SOX2 gene reduced the size of the stem/progenitor cell population and restored sensitivity to tamoxifen. Conversely, ectopic expression of Sox2 reduced tamoxifen sensitivity in vitro and in vivo. Gene expression profiling revealed activation of the Wnt signalling pathway in Sox2‐expressing cells, and inhibition of Wnt signalling sensitized resistant cells to tamoxifen. Examination of patient tumours indicated that Sox2 levels are higher in patients after endocrine therapy failure, and also in the primary tumours of these patients, compared to those of responders. Together, these results suggest that development of tamoxifen resistance is driven by Sox2‐dependent activation of Wnt signalling in cancer stem/progenitor cells.
Use of a Real-Time PCR TaqMan Assay for Rapid Identification and Differentiation of Burkholderia pseudomallei and Burkholderia mallei (2005)

A TaqMan allelic-discrimination assay designed around a synonymous single-nucleotide polymorphism was used to genotype Burkholderia pseudomallei and Burkholderia mallei isolates. The assay rapidly identifies and discriminates between these two highly pathogenic bacteria and does not cross-react with genetic near neighbors, such as Burkholderia thailandensis and Burkholderia cepacia.
Context-enhanced information fusion for tracking applications (2016)

Over the last decade, context has become a key source of information for tracking problems. Context inference allows refining sensor modeling and target dynamics as well as the creation of motion constraints according to the physical and operational conditions of the scenario. This work presents two example applications: indoor and inland waterway navigation where the context information is employed to reduce the uncertainty of the tracking and enhance the navigation solution. For indoor positioning a cascaded Extended Kalman Filter (EKF) and Particle Filter (PF) architecture is proposed. The system uses stance phase detection and the available floor map to construct the measurement models for the KF and motion constraints for the PF respectively. For navigating in inland waterways it is shown how to benefit from context information fusion by inferring the operating condition of the Global Navigation Satellite System (GNSS). In this scenario, context based criteria are derived for the selection of the best position estimation amongst several positioning solvers running in parallel. This work presents the basics for context fusion in tracking applications, illustrating the theory with two application examples. The preliminary results already demonstrate a performance improvement compared to state-of-the-art approaches.
Wavelength dependence and figures of merit of ultrafast third-order optical nonlinearity of a conjugated 3,3′-bipyridine derivative (2003)

The wavelength dependence and figures of merit of the third-order optical nonlinearity of a conjugated 3,3'-bipyridine derivative, a designed nondipolar structure of the donor-acceptor-acceptor-donor type, are reported. Z scans reveal positive nonlinear refractive-index changes for wavelengths longer than the one-photon absorption wavelength. Although the value of nonlinear Kerr coefficient n2 decreases from 6.0(+/- 0.2) x 10(-6) cm2/GW at 750 nm to 4.6(+/- 0.7) x 10(-6) cm2/GW at 1550 nm, the value of nonlinear absorption beta decreases from 0.084 cm/GW at 750 nm to a negligible value at 1550 nm, giving rise to excellent nonlinearity-to-loss figures of merit at telecommunications wavelengths.
Children’s acquisition of L2 Spanish morphosyntax in an immersion setting (2005)

This article reexamines Critical Period and L1/L2 differences by looking at the development of Spanish morphosyntax by young Anglophone immersion learners, in light of two hypotheses, Full Transfer/Full Access (FTFA) and Failed Functional Features (FFFH). FTFA maintains that syntax and morphology develop separately in L2 acquisition for adults and children, while FFFH holds that syntax is dependent on morphology development and that a post-Critical Period failure of morphosyntactic functional features contributes to an L1A/ adult L2A distinction. We first review L1A and L2A of Spanish morphosyntax and elaborate FFFH and FTFA. Then we describe our data collection, results and discussion in terms of the two hypotheses.We conclude that the child learners are sensitive to the importance of inflectional morphology (L1A-like), but make numerous errors (adult L2A-like). Their syntax develops more quickly and accurately than their morphology, supporting FTFA.
