SPECTROSCOPY AND STRUCTURE OF A HYDROGEN BONDED CIS AMIDE DIMER (2000)

Electronic spectra of the dimer of the cis amide oxindole and the complex of oxindole and formamide have been obtained in a supersonic jet expansion using mass-resolved resonant two-photon ionization spectroscopy. The experimental results are supportive of cyclic hydrogen bonded structures for both complexes. The oxindole chromophores in the dimer are equivalent and statistical deuteration reveals a small exciton splitting, indicative of an essentially localized excitation. Spectra of the oxindole dimer hydrated with one and two water molecules have also been obtained and have been interpreted by comparison to the dimer spectrum in conjunction with ab initio Hartree-Fock calculations.

Global Ranking of Documents Using Continuous Conditional Random Fields (2008)

This paper is concerned with ranking model construction in document retrieval. Traditionally, the ranking model is defined as a function of a query and a document. In practice, many factors affecting ranking can and must be taken into consideration, for instance, similarities between documents and hyper links between documents. One needs to exploit a new ranking model which is a function of a query and the entire set of documents retrieved with the query. This paper names this new problem ‘global ranking of documents’, in contrast to traditional ‘local ranking of documents’. The paper proposes a novel learning to rank method to perform the task. The method employs Continuous Conditional Random Fields (CRF) as model, which is a conditional probability distribution representing the mapping relationship from the retrieved documents to their ranking scores. The model can naturally utilize as features the content information of documents as well as the relation information between documents for global ranking. A learning algorithm for creating Continuous CRF is also presented in the paper. Taking Pseudo Relevance Feedback and Topic Distillation as examples, this paper shows how the learning method can be applied to global ranking. Experimental results on benchmark data show that the proposed method outperforms the baseline methods.
Neighborhood Adaptive Loss Function for Deep Learning-Based Point Cloud Coding With Implicit and Explicit Quantization (2020)

As the interest in deep learning tools continues to rise, new multimedia research fields begin to discover its potential. Both image and point cloud coding are good examples of technologies, where deep learning-based solutions have recently displayed very competitive performance. In this context, this article brings two novel contributions to the point cloud geometry coding state-of-the-art; first, a novel neighborhood adaptive distortion metric to be used in the training loss function, which allows significantly improving the rate-distortion performance with commonly used objective quality metrics; second, an explicit quantization approach at the training and coding times to generate varying rate/quality with a single trained deep learning coding model, effectively reducing the training complexity and storage requirements. The result is an improved deep learning-based point cloud geometry coding solution, which is both more compression efficient and less demanding in training complexity and storage.
PortSec 2.0: The next generation (2012)

The infrastructure systems at the ports of Los Angeles and Long Beach comprise the largest port complex within the United States, processing over forty percent of the nation's container traffic. Security within this port is critical to the regional and national economy. The University of Southern California's National Center for Risk and Economic Analysis of Terrorism Events, a Department of Homeland Security University Center of Excellence, has continued development of the Port Security Risk Assessment and Resource Management (PortSec) system to address a key challenge facing all port complexes - simultaneously increasing security, maximizing business throughput, and minimizing environmental impact. PortSec continues to focus on risk assessment from real-time intelligence sources for tactical operations. In this paper, ongoing advancements to PortSec, including the ability to interface with Unified Incident Command and Decision Support (UICDS) system, development of an economic impact model, and updates to the POLA/LB transportation model are reported.
Fast interrogation wavelength tuning for all-optical photoacoustic imaging (2023)

Optical detection of ultrasound for photoacoustic imaging provides a large bandwidth and high sensitivity at high acoustic frequencies. Therefore, higher spatial resolutions can be achieved using Fabry-Pérot cavity sensors than conventional piezoelectric detection. However, fabrication constraints during the deposition of the sensing polymer layer require precise control of the interrogation beam wavelength to provide optimal sensitivity. This is commonly achieved by employing slowly tunable narrowband lasers as interrogation sources, hence limiting the acquisition speed. We propose instead to use a broadband source and a fast-tunable acousto-optic filter to adjust the interrogation wavelength at each pixel within a few microseconds. We demonstrate the validity of this approach by performing photoacoustic imaging with a highly inhomogeneous Fabry-Pérot sensor.
Continuous Stability Monitoring of DC Microgrids Using Controlled Injection (2019)

Emerging dc microgrids incorporating energy storage are presenting new challenges in system design and stability analysis. Several methods have been proposed in literature for online stability evaluation of such dc microgrids using impedance-based stability analysis. This paper presents a method for continuous monitoring of system stability that is not computationally intensive and can be added as a supplemental function to existing converters in the system so that no additional power hardware is required. The proposed method evaluates stability continuously and can be used as a proactive approach for monitoring and maintaining system stability. Hardware results are presented to validate the proposed continuous stability monitor, which shows its effectiveness in predicting the system stability margins.

Pharmacokinetics of colistin methanesulphonate and colistin in rats following an intravenous dose of colistin methanesulphonate (2004)

Colistin appeared in plasma soon after administration of CMS, indicating rapid conversion of CMS into colistin. CMS had a shorter terminal half-life than did colistin, indicating that the disposition of the colistin generated from CMS was rate-limited by its elimination. Most of the dose was recovered in urine, half in the form of colistin. The high percentage of colistin recovered in urine was believed to be formed by hydrolysis of CMS in the bladder and in the collection vessel, and/or conversion from CMS in the kidney.
Inhibitors of Alphavirus Entry and Replication Identified with a Stable Chikungunya Replicon Cell Line and Virus-Based Assays (2011)

Chikungunya virus (CHIKV), an alphavirus, has recently caused epidemic outbreaks and is therefore considered a re-emerging pathogen for which no effective treatment is available. In this study, a CHIKV replicon containing the virus replicase proteins together with puromycin acetyltransferase, EGFP and Renilla luciferase marker genes was constructed. The replicon was transfected into BHK cells to yield a stable cell line. A non-cytopathic phenotype was achieved by a Pro718 to Gly substitution and a five amino acid insertion within non-structural protein 2 (nsP2), obtained through selection for stable growth. Characterization of the replicon cell line by Northern blotting analysis revealed reduced levels of viral RNA synthesis. The CHIKV replicon cell line was validated for antiviral screening in 96-well format and used for a focused screen of 356 compounds (natural compounds and clinically approved drugs). The 5,7-dihydroxyflavones apigenin, chrysin, naringenin and silybin were found to suppress activities of EGFP and Rluc marker genes expressed by the CHIKV replicon. In a concomitant screen against Semliki Forest virus (SFV), their anti-alphaviral activity was confirmed and several additional inhibitors of SFV with IC₅₀ values between 0.4 and 24 µM were identified. Chlorpromazine and five other compounds with a 10H-phenothiazinyl structure were shown to inhibit SFV entry using a novel entry assay based on a temperature-sensitive SFV mutant. These compounds also reduced SFV and Sindbis virus-induced cytopathic effect and inhibited SFV virion production in virus yield experiments. Finally, antiviral effects of selected compounds were confirmed using infectious CHIKV. In summary, the presented approach for discovering alphaviral inhibitors enabled us to identify potential lead structures for the development of alphavirus entry and replication phase inhibitors as well as demonstrated the usefulness of CHIKV replicon and SFV as biosafe surrogate models for anti-CHIKV screening.
Spicy SDS-PAGE Gels: Curcumin/Turmeric as an Environment-Friendly Protein Stain (2012)

Gel proteins are commonly stained with calorimetric/fluorescent dyes. Here, we demonstrate that heat-solubilized curcumin can serve as a nontoxic and environment-friendly fluorescent/colorimetric reversible protein stain. Curcumin, the yellow pigment found in the rhizomes of the perennial herb Curcuma longa (turmeric), is insoluble in aqueous solvents. However, heat (100°C) solubilization in water renders 1.5% of curcumin soluble. Curcumin solubilized by ethanol or alkali is ineffective in staining proteins. Heat solubilized curry spice turmeric stains proteins similarly. Staining is achieved in 30 min, with a sensitivity almost equaling that of Coomassie Brilliant Blue (CBB). Destaining is not required, and excess curcumin/turmeric can be discarded into the sink. Binding of proteins by silver inhibits curcumin binding, suggesting similarity of protein binding by silver and curcumin. It costs $1.5-2.0 to stain a mini-gel with curcumin, while turmeric costs less than 0.005 cent. CBB staining/destaining costs about 2 cents. However, CBB is toxic and its use necessitates specialized disposal efforts. Curcumin/turmeric, thus, can serve as an ideal nontoxic protein stain.
A Markovian random field approach to information retrieval (2002)

A Markovian random field approach is proposed for automatic information retrieval in full text documents. We draw up an analogy between a flow of queries/document images connections and statistical mechanics systems. The Markovian flow process machine (MFP) models the interaction between queries and document images as a dynamical system. The MFP machine searches to fit the user's queries by changing the set of descriptors contained in the document images. There is hence a constant transformation of the informational states of the fund. For each state, a certain degradation of the system is considered. We use simulated annealing algorithm to isolate low energy states: this corresponds to the best "matching" in some sense between queries and images.
Peptone stimulates gastrin secretion from the stomach by activating bombesin/GRP and cholinergic neurons (1992)

The mechanism by which partly digested protein (peptone) stimulates gastrin secretion was examined in isolated antral tissues with intact intramural innervation. In the isolated vascularly perfused rat stomach, luminal perfusion with 0.5% peptone increased gastrin (62 +/- 14 pg/min; P less than 0.01) and decreased somatostatin (74 +/- 19; P less than 0.01) secretion. The axonal blocker tetrodotoxin (TTX) abolished the gastrin and somatostatin responses indicating that the responses were neurally mediated. Atropine partly inhibited the gastrin response (50%) and converted the somatostatin response to an increase above basal level. The selective bombesin/gastrin-releasing peptide (GRP) antagonist [Leu13-psi(CH2NH)-Leu14]-bombesin partly inhibited the gastrin response (65%) and caused a further decrease in somatostatin secretion. A combination of atropine and the bombesin/GRP antagonist, like TTX, abolished the gastrin and somatostatin responses. The pattern of response to peptone in superfused antral segments was identical to that in the vascularly perfused stomach. In fundic segments that do not secrete gastrin, the somatostatin response to peptone alone and with various antagonists was identical to that in antral segments. The results indicate that peptone stimulates gastrin secretion by activating stimulatory cholinergic and bombesin/GRP neurons. Cholinergic neurons stimulate gastrin directly as well as indirectly by eliminating the inhibitory paracrine influence of somatostatin.
The 'best method' of topical nasal drug delivery: comparison of seven techniques. (2006)

Our study suggests there may not be a single 'best' technique for topical nasal drug delivery. A more individual approach to topical nasal drug treatment, taking anatomy and head position into account would seem to be more appropriate.
On the impact of microgrid energy management systems on power system dynamics (2017)

This paper compares the impact of microgrids on the transient response of the transmission system, and, more specifically, on its frequency variations, when different control strategies and different storage capacities are employed. Extensive Monte Carlo simulations are performed based on the IEEE 39-bus system, and show that the dynamic behavior of the transmission system is affected in a non-trivial way by the control strategy of the microgrids energy management system and their storage capacity.
Efficient Monte Carlo Filtering for Discretely Observed Jumping Processes (2007)

This paper addresses a tracking problem in which the unobserved process is characterised by a collection of random jump times and associated random parameters. We construct a scheme for obtaining particle approximations to the posterior distributions of interest in the framework of sequential Monte Carlo (SMC) samplers [1]. We describe efficient sampling schemes and demonstrate that two existing schemes can be interpreted as particular cases of the proposed method. Results are provided which illustrate the performance improvements possible with our approach.
Highly protective antimalarial antibodies via precision library generation and yeast display screening (2022)

The monoclonal antibody CIS43 targets the Plasmodium falciparum circumsporozoite protein (PfCSP) and prevents malaria infection in humans for up to 9 mo following a single intravenous administration. To enhance the potency and clinical utility of CIS43, we used iterative site-saturation mutagenesis and DNA shuffling to screen precise gene-variant yeast display libraries for improved PfCSP antigen recognition. We identified several mutations that improved recognition, predominately in framework regions, and combined these to produce a panel of antibody variants. The most improved antibody, CIS43_Var10, had three mutations and showed approximately sixfold enhanced protective potency in vivo compared to CIS43. Co-crystal and cryo-electron microscopy structures of CIS43_Var10 with the peptide epitope or with PfCSP, respectively, revealed functional roles for each of these mutations. The unbiased site-directed mutagenesis and screening pipeline described here represent a powerful approach to enhance protective potency and to enable broader clinical use of antimalarial antibodies.
DRAGON-West Japan campaign in 2012: regional aerosol measurements over Osaka (2012)

It is known that the aerosol distribution in Asia is complicated due to the increasing emissions of anthropogenic aerosols in association with economic growth and natural dust significantly varied with the seasons. Therefore it is clear that local spatially and temporally resolved measurements of atmospheric aerosols in Asian urban city are necessary. Since Osaka, Kobe, Kyoto, and Nara are located in very close each others (all cities are included in around 70×70 km<sup>2</sup> area). The population of the region is around 13 millions including neighbor prefectures, accordingly air quality in this region is slightly bad in comparison with the remote area. Furthermore, in recent years, Asian dusts and anthropogenic small particles some times transported from China and cover these cities throughout year. DRAGON (Distributed Regional Aerosol Gridded Observation Network) is a project of dense sun/sky radiometer network in the urban area. The DRAGON-West Japan field campaign was performed over Osaka and neighbor cities with 7 AERONET instruments from March to end of May in 2012. As results, DRAGON measurements indicate small differences among the values of AOT over Osaka region.

An Image Compression Scheme Based on Parametric Haar-like Transform (2005)

A new image compression scheme is presented, based on a fast orthogonal parametrically adaptive Haar-like transform, which is a discrete orthogonal transform such that it may be computed with a fast algorithm in structure similar to the classical fast Haar transform, and such that its matrix contains one or more predefined row(s) of an arbitrary order. The nature of the proposed image compression scheme is such that its performance (in terms of PSNR versus compression ratio) cannot be worse than that of the classical DCT (discrete cosine transform) based scheme. Simulations show that a significant performance improvement can be achieved for certain types of images such as medical X-ray images.
Evaluating the Power Output of the Smith-Root GPP 5.0 Electrofisher to Promote Electrofishing Fleet Standardization (2009)

Abstract The Smith-Root (S-R) series of GPP (gas-powered pulsator) electrofishers are widely used in boat-mounted electrofishing systems. Sampling in waters having different conductivities requires adjustment of the electrofisher controls to maintain consistent output power. However, the current meter supplied on GPP electrofishers provides an average rather than a peak measurement, and because no voltmeter is included, determining peak power output is not possible. As part of an overall effort to promote standardization of electrofishing operations, we used static electrical loads to measure the output characteristics of the commonly used S-R GPP 5.0 electrofishers under simulated electrofishing conditions. The range of resistance values to be simulated with static loads was extrapolated from in-water measurements of five electrode configurations consisting of paired, half-submerged, spherical anodes in combination with a 5.5-m-long flat-bottom aluminum-hull boat serving as the cathode. We measured the power output of GPP 5.0 electrofishers while they were connected to static loads of 114, 19, 9.5, and 5.7 Ω to simulate a wide range of ambient water conductivity values (approximately 100–1,000 μS/cm). These measurements of GPP 5.0 power output will provide electrofishing fleets with an improved understanding of electrofisher operational controls and performance and allow for a more consistent method of selecting electrofisher settings.
