Lipid Metabolism: A New Frontier in Sleep Apnea Research (2011)

CAM-ICU seems to be a very simple and time-efficient instrument.While the CAM-ICU attempts to capture disturbances in attention and cognition, it fails to capture the fluctuating nature of these disturbances since the evaluations are done at one point in time.Importantly, this may lead to underdiagnosis of delirium when compared with a comprehensive evaluation that takes into account documentation of these disturbances fluctuating over time, as investigators in this study found.The results of this study raise several important questions.(1) Was it the CAM-ICU as a screening instrument or the failure to actually follow each and every step that lead to its poor performance?(2) Are other tests of ICU delirium (e.g., Intensive Care Delirium Screening Checklist [ICDSC]) (10) subject to the same problems as the CAM-ICU?(3) What is/are the specific shortcoming(s) of the CAM-ICU?(4) Are the findings from this Netherlands study reproducible in other settings?If so, can the CAM-ICU be modified to overcome its potential shortcomings?(5) How, if at all, do the outcomes (short term and long term) that ICU delirium portends differ among patients with "gold standard" delirium versus delirium diagnosed by CAM-ICU?A screening tool must have a high sensitivity to be clinically useful.Are there inherent limitations to the CAM-ICU as a useful instrument for identifying ICU delirium?Such a finding would be analogous to the inherent limitation of ultrasound screening for asymptomatic deep vein thrombosis (11,12).On the other hand, improper use of any instrument may lead to a perception of limitations that is untrue.Further studies are needed to better answer this important question raised by this study.In the meantime, we should be cautious when using the CAM-ICU to screen patients for delirium, both in clinical and research settings.When it is used we must be certain that each step is followed precisely, and we should await further research to shed light on this important issue.
Spatial Variation of Air Toxics in the Village of Waterfront South in Camden, NJ (2006)

MM4-PD-03 There are numerous stationary (26 industrial and manufacturing facilities) and mobile (150,000–260,000 truck trips per year) sources located in or near the Village of Waterfront South (WFS) in Camden, NJ. With the intensity of local emission sources of air toxics, understanding spatial variation of air pollutants in the WFS is important to better characterize personal exposures to air toxics generated by local sources. Three “Saturation Samplings,” with sampling duration of 24 or 48 hours, were conducted in 2005 to identify the spatial variation of air toxics in the WFS and the Copewood/Davis Street area, an urban reference site located ~2 miles northeast of the WFS. Thirty-eight sampling sites (22 sites in the WFS and 16 sites in the CDS) were selected in each neighborhood in order to capture sufficient variability with regard to the proximity to the local industrial sources. The distance between each sampling site was approximately 250 m, but some were located within ~50 m of the stationary sources to investigate the impact of those industrial facilities on adjacent ambient pollutants levels. Two passive samplers were placed at each site to measure VOCs and carbonyl compounds, respectively. In general, most target air toxics were found higher in the WFS than in the CDS. The formaldehyde concentrations observed from 22 sites in the WFS ranged from 40 to 160 μg/m3, which are 2 to 5 times higher than typical urban formaldehyde levels (the mean concentration is 2–5 μg/m3), validating our hypothesis that the WFS is a “hotspot” for formaldehyde. A large variation was observed for toluene, ethylbenzene, xylenes, styrene, and Methyl tert-butyl ether (MTBE), depending on location. For example, about 200 μg/m3 toluene was observed at one site close to an industrial facility in the WFS; high concentration of ethylbenzene (6.2 μg/m3), xylenes (52.9 μg/m3), and styrene (0.30 μg/m3) were observed at one site within 150 m of a power plant; and 50.6 μg/m3 MTBE was found at one site next to a junk yard. These results indicated the impact of local sources of these air pollutants on ambient air pollution in the WFS. The data obtained from monitoring spatial variation of air toxics will help us to better quantify personal exposure to ambient air toxics, to refine exposure and air quality models, and to better design our second-phase study on health effect resulting from exposure to air toxics generated by local air pollution sources.
Targeted Expression of Human Vitamin D Receptor in Adipocytes Decreases Energy Expenditure and Induces Obesity in Mice (2011)

Our previous studies demonstrated a high fat diet-resistant lean phenotype of vitamin D receptor (VDR)-null mutant mice mainly due to increased energy expenditure, suggesting an involvement of the VDR in energy metabolism. Here, we took a transgenic approach to further define the role of VDR in adipocyte biology. We used the aP2 gene promoter to target the expression of the human (h) VDR in adipocytes in mice. In contrast to the VDR-null mice, the aP2-hVDR Tg mice developed obesity compared with the wild-type counterparts without changes in food intake. The increase in fat mass was mainly due to markedly reduced energy expenditure, which was correlated with decreased locomotive activity and reduced fatty acid β-oxidation and lipolysis in the adipose tissue in the transgenic mice. Consistently, the expression of genes involved in the regulation of fatty acid transport, thermogenesis, and lipolysis were suppressed in the transgenic mice. Taken together, these data confirm an important role of the VDR in the regulation of energy metabolism.
Emulsions and Solubilization (1986)

Containing information useful for demonstrating the relation between the function of Hydrophilic Lipophilic Balance (HLB) and solubilization, microemulsions and emulsion stability or inversion, this book covers the effect of temperature on systems containing nonionic surfactants and studies of the surfactant as a function of temperature. The book also demonstrates how the HLB solution properties of the surfactant can be controlled to change from water-soluble to oil-soluble.
Palladium‐Catalyzed Sixfold Alkenylation of Hexabromobenzene: An Interesting Case of Self‐Organization (1997)

Bowl-shaped hexakis(3,3-dimethyl-1-butenyl)benzene (1, see space-filling model on the right) was obtained from the Pd-catalyzed coupling of hexabromobenzene with 2-(3,3-dimethyl-1-butenyl)-1,3,2-benzodioxaborole. All six alkenyl groups are directed to one side of the benzene ring. Catalytic hydrogenation of 1 provides the corresponding hexakisalkylbenzene, which crystallizes in regular stacks; here the alkyl group are alternatingly above and below the ring.
Effect of nano-silica on Portland cement matrices containing supplementary cementitious materials (2021)

abstract: For a controlled granulometry, this study evaluates the effect of nano-silica on mechanical and rheological properties, as well in the microstructure of Portland cement matrices containing a fixed amount of supplementary cementitious materials and three different types of cements. The rheological behavior of cement pastes was evaluated by rotational rheometry and mechanical performance was measured througth the compressive strength. The microstructure was analyzed by intrusion mercury porosimetry and scanning electron microscopy. There was an increasing on the viscosity of the cementitious matrices, as a consequence of the reduction in the inter particle separation of these suspensions. The optimum content of nano-silica varied according to Ca/Si ratio of Portland cement matrices containing supplementary cementitious materials. The use of nano-silica allowed to modify the pore size distribution of cementitious matrices. And the structure of nano-silica in cementitious matrices has occurred in layers or agglomerates of nano-particles covered by hydration products.
A Cost-Effective and Portable Optical Sensor System to Estimate Leaf Nitrogen and Water Contents in Crops (2020)

Non-invasive determination of leaf nitrogen (N) and water contents is essential for ensuring the healthy growth of the plants. However, most of the existing methods to measure them are expensive. In this paper, a low-cost, portable multispectral sensor system is proposed to determine N and water contents in the leaves, non-invasively. Four different species of plants-canola, corn, soybean, and wheat-are used as test plants to investigate the utility of the proposed device. The sensor system comprises two multispectral sensors, visible (VIS) and near-infrared (NIR), detecting reflectance at 12 wavelengths (six from each sensor). Two separate experiments were performed in a controlled greenhouse environment, including N and water experiments. Spectral data were collected from 307 leaves (121 for N and 186 for water experiment), and the rational quadratic Gaussian process regression (GPR) algorithm was applied to correlate the reflectance data with actual N and water content. By performing five-fold cross-validation, the N estimation showed a coefficient of determination () of 63.91% for canola, 80.05% for corn, 82.29% for soybean, and 63.21% for wheat. For water content estimation, canola showed an of 18.02%, corn showed an of 68.41%, soybean showed an of 46.38%, and wheat showed an of 64.58%. The result reveals that the proposed low-cost sensor with an appropriate regression model can be used to determine N content. However, further investigation is needed to improve the water estimation results using the proposed device.
Dielectric and optical properties of epitaxial rare-earth scandate films and their crystallization behavior (2006)

Rare-earth scandates (ReScO3, with Re=Y, La, Pr, Nd, Sm, Gd, Tb, Dy, Ho, Er, Tm, Yb, and Lu, i.e., the entire series for which the individual oxides are chemically stable in contact with Si) were deposited in a temperature-gradient pulsed laser deposition system onto LaAlO3 substrates. The crystallization temperature depends monotonically on the Re atomic number and the Goldschmidt tolerance factor, with crystallization temperatures as low as 650°C for LaScO3 and PrScO3. The dielectric constants of the crystalline films K≈30 (determined by microwave microscopy) are significantly larger than those of their amorphous counterparts. In combination with the large observed band gaps (Eg&amp;gt;5.5eV, determined by ellipsometry), these results indicate the potential of these materials as high-K dielectrics for field-effect transistor applications.
Cross‐reactivity between Ficus benjamina latex and fig fruit in patients with clinical fig allergy (2003)

Allergic reactions to fresh or dried figs can present as a consequence of primary sensitization to airborne FB allergens independent of sensitization to rubber latex allergens. Kiwi fruit, papaya, and avocado as well as pineapple and banana may be other fruits associated with sensitization to Ficus allergens.
Petrologic insights from the spectra of the unbrecciated eucrites: Implications for Vesta and basaltic asteroids (2010)

Abstract– We investigate the relationship between the petrology and visible–near infrared spectra of the unbrecciated eucrites and synthetic pyroxene–plagioclase mixtures to determine how spectra obtained by the Dawn mission could distinguish between several models that have been suggested for the petrogenesis of Vesta’s crust (e.g., partial melting and magma ocean). Here, we study the spectra of petrologically characterized unbrecciated eucrites to establish spectral observables, which can be used to yield mineral abundances and compositions consistent with petrologic observations. No information about plagioclase could be extracted from the eucrite spectra. In contrast, pyroxene dominates the spectra of the eucrites and absorption band modeling provides a good estimate of the relative proportions of low‐ and high‐Ca pyroxene present. Cr is a compatible element in eucrite pyroxene and is enriched in samples from primitive melts. An absorption at 0.6 μm resulting from Cr 3+ in the pyroxene structure can be used to distinguish these primitive eucrites. The spectral differences present among the eucrites may allow Dawn to distinguish between the two main competing models proposed for the petrogenesis of Vesta (magma ocean and partial melting). These models predict different crustal structures and scales of heterogeneity, which can be observed spectrally. The formation of eucrite Allan Hills (ALH) A81001, which is primitive (Cr‐rich) and relatively unmetamorphosed, is hard to explain in the magma ocean model. It could only have been formed as a quench crust. If the magma ocean model is correct, then ALHA81001‐like material should be abundant on the surface of Vesta and the Vestoids.
Tumour S-phase activity, nucleotide profile and RNA levels after hepatic artery occlusion and reperfusion in an experimental model of secondary liver carcinoma (1995)

Rats with carcinoma of the colon implanted into the liver were subjected to hepatic arterial occlusion for 30-120 min. Regrowth of the tumour after reperfusion was evaluated by immunohistological determination of S-phase activity after injection of bromodeoxyuridine. Levels of RNA and nucleotides, and energy charge, were also examined. DNA synthesis was observed in the entire tumour except in necrotic areas of controls and after 30-min ischaemia with 2-h reflow. Almost all tumoral DNA synthesis was abolished by 2 h of ischaemia, except in a few cells in the tumour periphery, which after reperfusion for 22 and 40 h grew into a band-like concentric layer. Levels of energy charge, adenosine, uridine and guanosine 5'-triphosphates, and RNA were unchanged in liver tissue after hepatic arterial occlusion but decreased in the tumour. In conclusion 30 min of ischaemia did not damage the tumour cells substantially. Ischaemia for 2 h seemed able to kill the tumour cells except those in the periphery in areas nourished by the portal vein where tumour regrowth was seen. The liver tissue was not damaged.
A Novel and Flexible Laser Patterned Graphene Nanoplatelet Electrode With SPNs for Fast Charging Lithium-Ion Batteries (2023)

A flexible anode was developed with graphene nanoplatelet (xGnP) as the anode material for fabricating fast-charging lithium-ion batteries. The ink consists of xGnPs as active material along with C-45 carbon black as a conductive additive and polyvinylidene fluoride (PVDF) as a binder. The ink was bar coated onto two flexible copper films to form anodes with mass loadings of 2.8 and 7.2 mg/cm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> . Then the anode was laser patterned to introduce a secondary pore network (SPN) consisting of pores with a diameter of <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$\sim 33 \mu \text{m}$ </tex-math></inline-formula> and an edge-to-edge distance of <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$\sim 42 \mu \text{m}$ </tex-math></inline-formula> between the pores. The mass loadings of laser-patterned anodes were measured to be 2.1 and 5.6 mg/cm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> . Half-cell lithium-ion batteries (LIBs) were assembled with fabricated anodes with lithium metal foil as a counter electrode. Ethylene carbonate and diethyl carbonate (EC:DEC) in 50/50 (v/v) mixed with 1M lithium hexafluorophosphate (LiPF6) was used as an electrolyte in assembled coin-cells. Formation, rate, and cycling tests were performed for bar-coated (without SPN) and laser patterned (with SPN) cells with different mass loadings at different C-rates. Cells with SPNs exhibited higher specific capacities of 420, 315, and 207 mAh/g at high mass loading, at fast charging C-rates of 2, 4, and 6 C, respectively. Cells with SPNs showed superior capacity retention close to 90% when compared to cells without SPNs (38%) after 200 cycles at 2 C-rate. The effect of SPNs was significantly evident during the rate and cycling performance of anodes at high mass loading. This study demonstrated the significance of implementing SPNs in the electrodes for achieving fast-charging LIBs with high mass loading.
Inhibition by Liposomal Cholesterol ofStreptococcus PneumoniaeInduced Lung Epithelial Cell Damage (1999)

Streptococcus pneumoniae was shown to be capable of lysing A549 cells in culture. Membrane damage to cells as assessed by trypan blue exclusion increased with increasing concentration of bacteria. After 45 min of incubation with 7.5 × 108 bacteria/ml less than 20% of A549 cells excluded trypan blue. The lytic activity of S. pneumoniae was inhibited by phosphatidylcholine liposomes containing cholesterol. Using an haemolysis assay and S. pneumoniae's culture filtrates, the efficiency of the anti-lytic activity of liposomes was found to be distearoylphosphatidylcholine (DSPC) > dipalmitoylphosphatidylcho-line (DPPC) > dimyristoylphosphatidylcholine (DMPC). Furthermore, the anti-lytic activity also depended on the cholesterol content in a non-trivial manner. There was no protection against haemolytic activity at cholesterol content of less than 20% for DSPC and 35 mole% for DPPC and DMPC liposomes respectively. Above these threshold values inhibition of lytic activity increased sharply. In agreement with the haemolysis results, A549 cells were protected by liposomes against the lytic activity of S. pneumoniae with the efficiency also being DSPC > DPPC > DMPC. Clearly the efficiency of liposomal cholesterol is increased with increasing gel to liquid crystalline phase transition temperature of the lipid matrix. The results suggest that liposomal cholesterol may be used to protect the host against cell damage caused by S. pneumoniae.

Automated identification of components in raster piping and instrumentation diagram with minimal pre-processing (2016)

This paper proposes a novel framework for automated recognition of components in a Piping and Instrumentation Diagram (P&ID) of raster form. Contour is used as the main clue for visual recognition through the use of Local Binary Pattern (LBP) as descriptor and concept of Spatial Pyramid Matching (SPM). Comparison of two image patches is done by calculating the l1 distance between two corresponding LBP based descriptors. Firstly, the framework requires at least one example image per type of component to be recognised, the corresponding LBP and SPM based descriptor is determined and stored. Linear sliding window approach is used to detect a small set of top candidates from a pool of all sub-images in original image. Verification against the entire library of symbols is performed on each candidate selected from previous stage, using concept of nearest neighbour based classification. The method has demonstrated state of the art performance in a new challenging dataset created with advices from a group of experienced engineers in marine and offshore industry.

Improved Calcination Process of Barium Calcium Niobate Bcn18 and Its in Situ Application to Thermal Spraying (2008)

Problems arising by the solid-state reaction in the Ba3Ca1, 18Nb1, 82O9, (BCN18) system with perowskite structure are discussed. BCN18 is an interesting material for use in solid oxide fuel cells (SOFC) due to its high protonic conductivity at moderate temperatures. Trouble arises by the high solubility of BCN18-components in common crucible materials at temperatures above 1350 °C. This can be gathered from phase diagrams. Thus common crucible materials fail. Therefore the use of platinum crucibles is recommended. In this paper transformation of BCN18 to cubic phase at a temperature as low as 1350°C was investigated by extending the dwell time. Furthermore, a method of omitting the third calcining step by plasma spraying the hexagonal powders is presented.
