JPL/USC GAIM: On the impact of using COSMIC and ground‐based GPS measurements to estimate ionospheric parameters (2010)

The University of Southern California (USC) and the Jet Propulsion Laboratory (JPL) have jointly developed the Global Assimilative Ionospheric Model (GAIM) to monitor space weather, study storm effects, and provide ionospheric calibration for space weather applications. JPL/USC GAIM is a physics‐based 3‐D data assimilation model that uses both four‐dimensional variational analysis and Kalman‐filter techniques to solve for the ion and electron density state and key drivers such as equatorial electrodynamics, neutral winds, and production terms. Here we report on GAIM Kalman filter‐based assimilation results using ground‐based GPS and COSMIC‐derived total electron count (TEC) measurements. We find that assimilating COSMIC measurements into GAIM improves critical ionospheric parameters such as NmF2 and HmF2. Assimilating COSMIC data produces higher‐accuracy vertical electron density profile “shapes,” as verified by comparisons to independent electron density profiles measured at Arecibo, Jicamarca, and Millstone Hill incoherent scatter radar (ISR). We also find significant improvement in global vertical TEC (VTEC) maps when assimilating COSMIC measurements, verified by comparing GAIM output with VTEC measurements from the Jason ocean altimeter. For 3 days in June 2006, improvement in accuracy compared to ground‐data‐only assimilation is found to be 30%, 28%, and 44%, respectively.
Synthesis and Mass Spectral Data of four Potential Biomarkers Related to the C19Tricyclanes Found in Australian Oils and Puget Sound Sediments (1995)

Abstract The synthesis of four potential biomarkers, 13α-, 13β, 14α- and 14β-ethyl-8β(H)-podocarpane is reported. GC-MS comparison with an Australian oil C19 tricyclane and the mass spectra of two Puget Sound C19-terpanes evidenced non-identity of the synthetic compounds with the natural products; thus, proposed structures should be revised.
LARGE-SCALE MONITORING OF AUTOMOBILE EXHAUST PARTICULATES; METHODS AND COST (1971)

Abstract : The hypothetical problem addressed is annual monitoring of 150 million cars for exhaust particlates. Four topics are reviewed concerning the particulates: Total mass expressed in grams per mile; Particle size distribution; Elemental analysis; State of chemical combination. At present the only specification is in grams per mile but consideration is being given to particle size and to elemental analysis of known harmful constituents. Since manufacturers will not be told how to meet the specifications, a wide variety of emission control systems may be expected and along with them a wide variety of particulate compositions.

WE‐C‐BRA‐05: Physiological Imaging‐Defined Response‐Driven Subvolumes of a Tumor (2012)

Purpose: To develop an image analysis framework to delineate the physiological imaging‐defined subvolumes of a tumor in relating to treatment response and outcome. Methods: Our proposed approach is designed to delineate subvolumes of a tumor based upon its heterogeneous distributions of physiological imaging parameters. The method assigns each voxel a probabilistic membership function belonging to the physiological parameter classes based upon a sample of tumors, and then calculates the related subvolumes for each tumor. We applied our approach to regional cerebral blood volume (rCBV) and Gd‐DTAP transfer constant (Ktrans) images of patients who had brain metastases and were treated by whole brain radiation therapy (WBRT). Forty five lesions were included in the analysis. Changes in the rCBV (or Ktrans)‐defined subvolumes of the tumors from pre RT to 2 weeks (2W) after the start of WBRT were evaluated for differentiation of responsive, stable and non‐responsive tumors using Mann‐Whitney U test. Performance of the newly developed metrics for predicting tumor response to WBRT was evaluated by Receiver Operating Characteristic (ROC) analysis. Results: The percentage decrease in the high‐CBV defined subvolumes of the tumors from pre‐RT to 2W was significantly greater in the group of responsive tumors than in the group of stable and nonresponsive ones (p&lt;0.007). The change in the high‐CBV defined subvolumes of the tumors from pre‐RT to 2W was a predictor for post‐RT response significantly better than the change in gross tumor volume observed during the same time interval (p=0.0124), suggesting the physiological change occurs prior to the volumetric change. Also, Ktrans did not add significant discriminatory information for assessing response with respect to rCBV. Conclusions: The physiological imaging‐defined subvolumes of the tumors delineated by our method have the potential to be a new imaging response‐predictor and a candidate for intensified treatment.

Breakout force required for jack-up spudcan extraction from sand-over-clay seabeds (2020)

Spudcan retrieval from clay soils remains a major concern offshore as the extraction force required to overcome suction and soil resistance often exceeds the pulling capacity available on the mobile jack-up, causing extensive delays. Although methods to calculate extraction resistance have been recently suggested for seabeds of pure clay, to date there is no guidance available for the commonly encountered sand-over-clays. Based on failure mechanisms observed in half-spudcan visualisation tests, and calibrated against an extensive geotechnical centrifuge database of precisely measured extractions, this paper presents a method for calculating the force required to extract the spudcan foundations of mobile jack-up platforms after they have penetrated through a sand layer into underlying clay. Complexities, such as the strength degradation and strength recovery of the underlying clay soil, that occurs during spudcan installation and jack-up operations, are accounted for. Validation of the proposed method is demonstrated by retrospective prediction of the centrifuge testing database. The method outlined will allow operators of jack-up platforms to assess the extraction force prior to jack-up installation and to plan operational scenarios based on seabed conditions.
pH‐Stimulated DNA Hydrogels Exhibiting Shape‐Memory Properties (2014)

Nucleic acid-functionalized polyacrylamide chains that are cooperatively cross-linked by i-motif and nucleic acid duplex units yield, at pH 5.0, DNA hydrogels exhibiting shape-memory properties. Separation of the i-motif units at pH 8.0 dissolves the hydrogel into a quasi-liquid phase. The residual duplex units provide, however, a memory code in the quasi-liquid allowing the regeneration of the hydrogel shape at pH 5.0.
STATIC MODULUS OF ELASTICITY OF STEEL FIBER REINFORCED CONCRETE (2005)

An investigation on static modulus of elasticity of an M20 grade design mix of concrete with addition of four different percentages of steel fibre has been reported. The mix proportion 1:1.40:3.30, (w/c = 0.44) for M20 grade of concrete has been considered as reference mix. An addition of superplasticizer for increasing the workability of the concrete mix and reducing the ball effect of fibre has been chosen. Steel fibre of straight round type having 0.5 mm diameter and 25.4 mm length with four different percentages 0.25%, 0.50%, 0.75% and 1.00% by volume of the concrete has been adopted. All together 30 specimens were cast, cured normally for 28 days and then tested to failure. The static modulus of elasticity of the concrete was determined using standard cylinder specimens of size 150 mm diameter and 300 mm height. Test results show that the static modulus of elasticity obtained for fibre reinforced concrete increases up to 23% as compared to conventional concrete. The better bond in the fibre added concrete mix produces increase strength and ductility. INTRODUCTION EXPERIMENTAL PROGRAMME TESTING AND TEST RESULTS RESULTS AND DISCUSSION CONCLUDING REMARKS
Unified steady-state analysis of soft-switching DC-DC converters (2002)

In this paper, based on the switching cell approach, a unified steady state analysis for families of soft-switching DC-DC converters with complete unified design equations will be presented. The concept of the unified approach and step by step procedure for a generalized process are discussed and applied to selected soft-switching families such as zero-voltage-switching (ZVS) and zero-current-switching (ZCS)-quasi-resonant converter families, ZVS-clamped voltage quasi-square-wave (QSW) family, ZCS-clamped-current (CC) QSW family, and zero-voltage-transition and zero-current-transition pulse-width modulation families. Also, it has been noted that all the analyzed families have one generalized transformation table. The basic unified equations are summarized and the cell-to-cell comparison will be introduced. It will be shown that the unified analysis leads to several advantages such as improving the computer-aided analysis and design, simplified mathematical modeling, and giving more insight into the converter-cell operation.

Poly(glucosyl-N-acetylgalactosamine 1-phosphate), a wall teichoic acid of Bacillus subtilis 168: its biosynthetic pathway and mode of attachment to peptidoglycan (2006)

The ggaAB operon of Bacillus subtilis 168 encodes enzymes responsible for the synthesis of poly(glucosyl N-acetylgalactosamine 1-phosphate) [poly(GlcGalNAc 1-P)], a wall teichoic acid (WTA). Analysis of the nucleotide sequence revealed that both GgaA and GgaB contained the motif characteristic of sugar transferases, while GgaB was most likely to be bifunctional, being endowed with an additional motif present in glucosyl/glycerophosphate transferases. Transcription of the operon was thermosensitive, and took place from an unusually distant sigma(A)-controlled promoter. The incorporation of the poly(GlcGalNAc 1-P) precursors by various mutants deficient in the synthesis of poly(glycerol phosphate), which is the most abundant WTA of strain 168, revealed that both WTAs were most likely to be attached to peptidoglycan (PG) through the same linkage unit (LU). The incorporation of poly(GlcGalNAc 1-P) precursors by protoplasts confirmed the existence of this LU, and provided further evidence that incorporation takes place at the outer surface of the protoplast membrane. The data presented here strengthen the view that biosynthesis of the LU, and the hooking of the LU-endowed polymer to PG, offer distinct widespread targets for antibiotics specific to Gram-positive bacteria.
The distinct co-stimulatory requirements for thymic MAIT and NKT cell development (2021)

Abstract Mucosal-associated invariant T (MAIT) cells are a unique lineage of T cells that develop in the thymus. MAIT cells are positively selected by TCR recognition of microbial metabolite / MHC Class I-like molecule MR1 complexes presented on CD4/CD8 double-positive thymocytes. The developmental program of MAIT cells has been characterized as similar to that of invariant Natural Killer T (NKT) cells. Both MAIT and NKT cells acquire innate-like effector phenotypes during thymic development, and in each case differentiate into multiple subsets, with mature NKT cells categorized as either NKT1, NKT2 or NKT17, and mature MAIT cells as MAIT1 or MAIT17. We previously found distinct B7/CD28 and CD40L/CD40 co-stimulatory requirements for the development of thymic NKT subsets in BALB/c mice. In the absence of B7/CD28 co-stimulation, all NKT subsets were decreased, while only the NKT2 subset was specifically abrogated when lacking CD40L/CD40 co-stimulation. In the present study, we investigated the co-stimulatory requirements for MAIT cell development. Interestingly, MAIT17 cells were significantly increased when lacking either B7 or CD40 co-stimulation, while MAIT1 development was largely unaffected. These results revealed distinct co-stimulatory requirements for the thymic development of MAIT and NKT subsets. We are currently investigating the underlying mechanisms leading to the increase of MAIT17 cells in the absence of co-stimulatory signals.

Distribution of prosome proteins and their relationship with the cytoskeleton in oogenesis of Xenopus laevis (1994)

The presence of prosome proteins (p25K and p27K) was shown and their distribution was studied in oogenesis of Xenopus laevis using immunoblotting and immunofluorescence. These proteins form numerous granular clusters of variable size all over the cell. At previtellogenic stages, the prosome antibodies homogeneously stain the oocyte nucleus and the evenly distributed relatively large clusters in the cytoplasm. As the oocyte grows, the pattern of distribution of the prosome proteins undergoes changes: animal-vegetal and cortical gradients appear in the cytoplasm. In the course of oocyte maturation the size of clusters diminishes. Artificial activation of the egg leads to a dorso-ventral gradient in distribution of the prosome proteins. In this way, specific localization of prosome proteins is first visualized during formation of the dorso-ventral polarity. Co-localization of prosome proteins and actin and myosin was found in the oocyte by double staining. Small clusters of prosomes dispersed in the cytoplasm acquire capability of movement (after artificial activation) due, in all likelihood, to persisting connection with the acto-myosin complex of the egg.
Influence of Carrier Injection on Characteristics of an Organic Field Effect Transistor (2011)

The characteristic of an organic field effect transistor (OFET) depends strongly on both properties of an organic film and a carrier injection phenomenon. We have investigated the influence of carrier injection at the interface between the source electrode and the organic film on the characteristics of an OFET using a rubrene single crystal. The mobility estimated from the transfer characteristic of the OFET depended strongly on the channel length and the thickness of the rubrene single crystal although the mobility is intrinsically independent of the dimensions of an OFET. On the other hand, the temperature dependence of the saturation drain current was in good agreement with the thermal-field emission theory. These suggest that OFETs are controlled by not only the carrier accumulation at the channel but also the carrier injection.
Transcranial Direct Current Stimulation in Stroke Recovery (2008)

Transcranial direct current stimulation (TDCS) is an emerging technique of noninvasive brain stimulation that has been found useful in examining cortical function in healthy subjects and in facilitating treatments of various neurologic disorders. A better understanding of adaptive and maladaptive poststroke neuroplasticity and its modulation through noninvasive brain stimulation has opened up experimental treatment options using TDCS for patients recovering from stroke. We review the role of TDCS as a facilitator of stroke recovery, the different modes of TDCS, and the potential mechanisms underlying the neural effects of TDCS.
Organ specificity and transcriptional control of metabolic routes revealed by expression QTL profiling of source-sink tissues in a segregating potato population (2012)

Investigation of molecular dimensions of polystyrene as a function of the solvent composition: application to liquid chromatography at the exclusion-adsorption transition point (1999)

Liquid chromatography of polystyrene standards at the exclusion-adsorption transition point was undertaken with silica adsorbents of different porosity in various eluents. To better understand the elementary phenomena involved in these peculiar conditions, we have investigated by viscometry and light scattering the behavior of model polystyrene chains in solvent mixtures corresponding to the critical conditions. This study shows that the “critical conditions” can be obtained if the polymer chains enter the pores of the absorbent and also that this technique is limited to a certain molar mass range. The polarity index, P′, of the eluent, reflecting its ability to interact with the polymer chains and also with the stationary phase, is the parameter to be considered to define the characteristics of this elution mode.
Mild cognitive impairment: when nutrition helps brain energy rescue—a report from the EuGMS 2020 Congress (2021)

Organic Conducting Polymer–Protein Interactions (2012)

In this review, we provide insight into protein interactions with organic conducting polymers, a class of “intelligent” and dynamic materials that offer unique strategies for controlling protein interactions as a prelude to developing a wide range of bioapplications. Following a general introduction on the importance of protein interactions, this review initially focuses on the areas of bioseparation and biosensor applications. These applications amount to an extensive body of work; however, we provide only a brief overview for the purpose of introducing palpable examples of translating the ability to control organic conducting polymer–protein interactions into practical and useful applications. Because organic conducting polymers are breaking new ground for implantable electrodes and tissue regeneration/engineering, we duly turn to the importance of protein interactions and role organic conducting polymers can play in advancing these applications. Lastly, for those not familiar with organic conducting polymers, we take a step back and examine the unique properties underlying their innate ability to control protein interactions, particularly the use of external electrical control to reversibly switch the physical surface properties. Several characterization techniques identified as being critical to our understanding at the macroscopic down to the single molecule level are also highlighted.
