Primaquine Resistance in Plasmodium vivax (1996)

Reports have appeared calling attention to what has been termed primaquine resistance in Plasmodium vivax in several geographic areas. The possibility exists that primaquine tolerant strains (often referred to as the tropical zone type from the South Pacific and Southeast Asian regions characterized by early and frequent relapses) may have become widely disseminated to areas where they had not previously existed through the widespread population mobility that has characterized the last 50 years. The appearance in the relatively recent past of strains of P. vivax, particularly from the South Pacific area, that are resistant to the 4-aminoquinolines has added a new dimension to the resistance problem. While there seems to be little evidence to date of the existence of acquired primaquine resistance in P. vivax, the possibility of its emergence in the future can certainly not be ruled out, and its timely detection and confirmation will be most important, albeit quite difficult because of the relatively covert sites of drug effect. The occurrence of relapses in P. vivax after primaquine therapy would be assumed to be the most reliable indication of resistance. Reports of the sporontocidal or gametocytocidal activity of primaquine when used alone (i.e., without concomitant administration of an effective suppressive) against a P. vivax infection have been few and inconclusive. The establishment of baselines of this activity in P. vivax might be useful in detecting and evaluating primaquine resistance in this species.
A partial order for the synthesized channels of a polar code (2016)

A partial order for the synthesized channels W <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">N</sub> <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">(i)</sup> of a polar code is presented that is independent of the underlying binary-input channel W. The partial order is based on the observation that W <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">N</sub> <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">(j)</sup> is stochastically degraded to W <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">N</sub> <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">(i)</sup> if j is obtained by swapping a more significant 1 with a less significant 0 in the binary expansion of i. We derive an efficient representation of the partial order, the so-called covering relation. The partial order is then combined with another partial order from the literature that is also independent of W. Finally, we give some remarks on how this combined partial order can be used to simplify code construction of polar codes.
Toward event recognition using dynamic trajectory analysis and prediction (2005)

In this paper we propose a trajectory analysis method suited for event recognition. The method works online, in the sense that it can process the data as they are acquired by the sensors and it is dynamic, since it adapts the results to the changes in the patterns of activity. For each class of objects detected by the system, the proposed method groups trajectories with common features in clusters and, based on the identification of common prefixes in the clusters, can make probabilistic predictions on the possible future positions of a moving object. This analysis can give valuable information to an event recognition system for the identification of anomalous events.

UV inactivation of pathogenic and indicator microorganisms (1985)

Survival was measured as a function of the dose of germicidal UV light for the bacteria Escherichia coli, Salmonella typhi, Shigella sonnei, Streptococcus faecalis, Staphylococcus aureus, and Bacillus subtilis spores, the enteric viruses poliovirus type 1 and simian rotavirus SA11, the cysts of the protozoan Acanthamoeba castellanii, as well as for total coliforms and standard plate count microorganisms from secondary effluent. The doses of UV light necessary for a 99.9% inactivation of the cultured vegetative bacteria, total coliforms, and standard plate count microorganisms were comparable. However, the viruses, the bacterial spores, and the amoebic cysts required about 3 to 4 times, 9 times, and 15 times, respectively, the dose required for E. coli. These ratios covered a narrower relative dose range than that previously reported for chlorine disinfection of E. coli, viruses, spores, and cysts.
Probing Exciton Diffusion and Dissociation in Single-Walled Carbon Nanotube–C<sub>60</sub> Heterojunctions (2016)

The efficiency of thin-film organic photovoltaic (OPV) devices relies heavily upon the transport of excitons to type-II heterojunction interfaces, where there is sufficient driving force for exciton dissociation and ultimately the formation of charge carriers. Semiconducting single-walled carbon nanotubes (SWCNTs) are strong near-infrared absorbers that form type-II heterojunctions with fullerenes such as C60. Although the efficiencies of SWCNT-fullerene OPV devices have climbed over the past few years, questions remain regarding the fundamental factors that currently limit their performance. In this study, we determine the exciton diffusion length in the C60 layer of SWCNT-C60 bilayer active layers using femtosecond transient absorption measurements. We demonstrate that hole transfer from photoexcited C60 molecules to SWCNTs can be tracked by the growth of narrow spectroscopic signatures of holes in the SWCNT "reporter layer". In bilayers with thick C60 layers, the SWCNT charge-related signatures display a slow rise over hundreds of picoseconds, reflecting exciton diffusion through the C60 layer to the interface. A model based on exciton diffusion with a Beer-Lambert excitation profile, as well as Monte Carlo simulations, gives the best fit to the data as a function of C60 layer thickness using an exciton diffusion length of approximately 5 nm.

A proposal for a coherent mammalian histone H1 nomenclature correlated with amino acid sequences (1994)

Bio-Rex 70 chromatography was combined with reverse-phase (RP) HPLC to fractionate histone H1 zero and 4 histone H1 subtypes from human placental nuclei as previously described (Parseghian MH et al., 1993, Chromosome Res 1:127-139). After proteolytic digestion of the subtypes with Staphylococcus aureus V8 protease, peptides were fractionated by RP-HPLC and partially sequenced by Edman degradation in order to correlate them with human spleen subtypes (Ohe Y, Hayashi H, Iwai K, 1986, J Biochem (Tokyo) 100:359-368; 1989, J Biochem (Tokyo) 106:844-857). Based on comparisons with the sequence data available from other mammalian species, subtypes were grouped. These groupings were used to construct a coherent nomenclature for mammalian somatic H1s. Homologous subtypes possess characteristic patterns of growth-related and cAMP-dependent phosphorylation sites. The groupings defined by amino acid sequence also were used to correlate the elution profiles and electrophoretic mobilities of subtypes derived from different species. Previous attempts at establishing an H1 nomenclature by chromatographic or electrophoretic fractionations has resulted in several misidentifications. We present here, for the first time, a nomenclature for somatic H1s based on amino acid sequences that are analogous to those for H1 zero and H1t. The groupings defined should be useful in correlating the many observations regarding H1 subtypes in the literature.
Portal Services for Collaborative Remote Instrument Control, Monitoring and Data Access (2007)

A two component portal system is being developed for collaborative remote instrument and data control and monitoring. The system builds on and enhances the common instrument middleware architecture (CIMA) model for Web services based monitoring of remote scientific instruments and sensors. The architecture supports remote access to multiple instruments from a single portal. Plugin modules are used to provide flexibility and re-use, and the notion of plugin control is being developed. The use of Web 2.0 Pushlet and AJAX technologies has been introduced for push based portlet refresh and updating. An X3D based 3D virtual representation of the instrument provides data collection simulation and (pseudo) real time instrument representation. An important component of the system is a Webs services driven portlet for collaborative image viewing.
Molecular targets of the natural antioxidant pterostilbene: effect on protein kinase C, caspase-3 and apoptosis in human neutrophils in vitro. (2010)

Pterostilbene, an analog of resveratrol, was identified as a good natural antioxidant compound. However, reducing the oxidative burst of human neutrophils during their activation in vitro with pterostilbene does not include protein kinase C phosphorylation pathway. Pterostilbene showed dose dependent activation/inhibition of caspase-3 enzyme activity.
Model reactions and formation of epoxy networks with the phenylbenzoate mesogen (1997)

The phenylbenzoate mesogen was introduced into epoxy networks by the crosslinker 4-hydroxyphenyl-4-hydroxybenzoate and by the diglycidylether of 4-hydroxyphenyl-4-hydroxybenzoate, respectively. Rigid networks were synthesized on the basis of 4-hydroxyphenyl-4-hydroxybenzoate and the diglycidylether of bisphenol A, and flexible networks were prepared by reaction of the diglycidylether of butanediol-1.4 with the same dihydroxy compound. Model investigations were used to obtain information about the reactivity differences of the phenolic hydroxyl groups of the bisphenol used for network formation. Furthermore, the thermal properties of the main products isolated from the model reactions are strongly influenced by the substituents at the phenylbenzoate structure. Some of these model substances demonstrate structures that can be also found in the networks. In addition, photoinduced cationic crosslinking of the diglycidylether of 4-hydroxyphenyl-4-hydroxybenzoate results in networks with different thermal properties that are dependent on the temperature of network formation. Moreover, the temperature used during crosslinking influences the formation of ordered structures in the networks. © 1997 John Wiley & Sons, Inc. J Polym Sci A: Polym Chem 35: 2653–2688, 1997
BAY AREA RAPID TRANSIT DISTRICT REGIONAL RAIL PLANNING (1994)

In 1956 the ultimate regional rail plan was proposed for the San Francisco Area: a seamless, uniform mode encircling the bay. A 71.5-mi portion of the original core Area Rapid Transit (BART) system was adopted by voters in 1962 and completed in 1974. It has taken many years within the complex Area decision-making arena to implement the next generation of BART: 35 mi of new track scheduled to open within the next few years. Although further BART extensions remain unfunded, the vision of a regional rail system that rings the Bay has been brought within reach with an affordable plan to implement 200 mi of commuter rail service. The BART Extension Program and the practice of regional rail planning at BART are reviewed. It is concluded that the BART regional rail system can be multimodal and that service in a corridor can take many forms as it evolves over time.
Bootstrap - Inspired Techniques in Computation Intelligence (2007)

This article is about the success story of a seemingly simple yet extremely powerful approach that has recently reached a celebrity status in statistical and engineering sciences. The hero of this story - bootstrap resampling - is relatively young, but the story itself is a familiar one within the scientific community: a mathematician or a statistician conceives and formulates a theory that is first developed by fellow mathematicians and then brought to fame by other professionals, typically engineers, who point to many applications that can benefit from just such an approach. Signal processing boasts some of the finest examples of such stories, such as the classic story of Fourier transforms or the more contemporary tale of wavelet transforms.
Low-noise high-speed dc superconducting quantum interference device magnetometer with simplified feedback electronics (1990)

A dc superconducting quantum interference device (SQUID) magnetometer has been integrated on a 9×9 mm2 chip with eight pick-up loops in parallel to directly form a SQUID inductance of about 0.5 nH. Very simple feedback electronics have been developed which do not require liquid-helium temperature impedance matching circuits or flux modulation techniques. The magnetometer has a typical white noise of 8 fT/(Hz)1/2 and a 1/f corner frequency below 3.5 Hz. With an additional positive feedback circuit at 4.2 K the white noise level has been further reduced to 4.5 fT/(Hz)1/2. Using a two-pole integrator, a 3 dB bandwidth around 0.5 MHz and a maximum slew rate of 3 mT/s at 1.3 kHz have been attained with a ±0.4 μT feedback range.
Phenotypic and Genomic Variation among <i>Staphylococcus epidermidis</i> Strains Infecting Joint Prostheses (1999)

We studied the SmaI and SstII macrorestriction patterns of 54 Staphylococcus epidermidis strains isolated from 14 patients infected following the implantation of joint prostheses. Multiple strains from pus and infected tissue specimens of each patient were selected on the basis of different colony morphologies and drug resistance patterns. The same criteria were used to select 23 S. epidermidis strains from hand swabs of eight healthy individuals. For 10 of the 14 patients, all the intrapatient strains appeared to be closely or possibly related, whereas related strains were detected in the skin flora of only one of the eight healthy individuals. This observation suggests that, in most cases, the patients were infected by a single S. epidermidis clone which subsequently underwent rearrangements that yielded derivatives with divergent phenotypes and, occasionally, divergent macrorestriction patterns. The four patients whose specimens contained unrelated S. epidermidis strains were probably infected with several polyclonal strains.
Drogue detection for autonomous aerial refueling based on convolutional neural networks (2016)

Drogue detection is a fundamental issue during the close docking phase of autonomous aerial refueling (AAR). To cope with this issue, a novel and effective method based on deep learning with convolutional neural networks (CNNs) is proposed. In order to ensure its robustness and wide application, a deep learning dataset of images was prepared by utilizing real data of “Probe and Drogue” aerial refueling, which contains diverse drogues in various environmental conditions without artificial features placed on the drogues. By employing deep learning ideas and graphics processing units (GPUs), a model for drogue detection using a Caffe deep learning framework with CNNs was designed to ensure the method’s accuracy and real-time performance. Experiments were conducted to demonstrate the effectiveness of the proposed method, and results based on real AAR data compare its performance to other methods, validating the accuracy, speed, and robustness of its drogue detection ability.
Frequency-domain measurement of indoor UWB channels (2004)

A frequency-domain approach for propagation measurements and characterization of indoor ultra-wideband (UWB) channels is presented. The approach is based on measurement of the magnitude using a scalar network analyzer and retrieving the phase from the magnitude data using a Hilbert transform relationship. Extensive propagation data are collected in a frequency range of 1 to 12 GHz in two buildings on the Virginia Tech campus. Using the measured data, channel-characterization results are obtained and compared to those based on time-domain measurements. The statistical results for small-scale fading, the path-loss exponent, and signal quality are presented. The frequency-domain results are generally in good agreement with the time-domain results, and also reaffirm the immunity of UWB propagation to small-scale fading. © 2004 Wiley Periodicals, Inc.

Vehicle License Plate Detection Method Based on Sliding Concentric Windows and Histogram (2009)

Detecting the region of a license plate is the key component of the vehicle license plate recognition (VLPR) system. A new method is adopted in this paper to analyze road images which often contain vehicles and extract LP from natural properties by finding vertical and horizontal edges from vehicle region. The proposed vehicle license plate detection (VLPD) method consists of three main stages: (1) a novel adaptive image segmentation technique named as sliding concentric windows (SCWs) used for detecting candidate region; (2) color verification for candidate region by using HSI color model on the basis of using hue and intensity in HSI color model verifying green and yellow LP and white LP, respectively; and (3) finally, decomposing candidate region which contains predetermined LP alphanumeric character by using position histogram to verify and detect vehicle license plate (VLP) region. In the proposed method, input vehicle images are commuted into grey images. Then the candidate regions are found by sliding concentric windows. We detect VLP region which contains predetermined LP color by using HSI color model and LP alphanumeric character by using position histogram. Experimental results show that the proposed method is very effective in coping with different conditions such as poor illumination, varied distances from the vehicle and varied weather.

A quantum-well-intermixing process for wavelength-agile photonic integrated circuits (2002)

Wavelength-agile photonic integrated circuits are fabricated using a one-step ion implantation quantum-well intermixing process. In this paper, we discuss, the issues in processing optimized widely tunable multisection lasers using this technique and present the results achieved using this process. This quantum-well intermixing process is general in its application and can be used to monolithically integrate a wide variety of optoelectronic components with widely tunable lasers.
Electron states, magnetism, and the Verwey transition in magnetite (1991)

Using density-functional calculations, we examine the electronic structure of magnetite in the spinel crystal structure in order to gain insight into the nature of the Verwey transition. The calculated cohesive and magnetic properties are in agreement with experimental results. The magnetic structure is analyzed using a Stoner model as well as from calculations within the framework of the local-spin-density approximation to the density-functional theory. The calculations show a minority-spin band at the Fermi energy consisting of ${\mathit{t}}_{2\mathit{g}}$ orbitals on the Fe(B) sublattice. These results suggest a three-band spinless model Hamiltonian for the description of the Verwey transition. The hopping integrals and the electron interaction parameters entering the model Hamiltonian are calculated using the ``constrained'' density-functional theory. The calculated parameters are consistent with the electronic origin of the Verwey transition.
Free-Flow Zone Electrophoresis of Peptides and Proteins in PDMS Microchip for Narrow pI Range Sample Prefractionation Coupled with Mass Spectrometry (2010)

In this paper, we are evaluating the strategy of sorting peptides/proteins based on the charge to mass without resorting to ampholytes and/or isoelectric focusing, using a single- and two-step free-flow zone electrophoresis. We developed a simple fabrication method to create a salt bridge for free-flow zone electrophoresis in PDMS chips by surface printing a hydrophobic layer on a glass substrate. Since the surface-printed hydrophobic layer prevents plasma bonding between the PDMS chip and the substrate, an electrical junction gap can be created for free-flow zone electrophoresis. With this device, we demonstrated a separation of positive and negative peptides and proteins at a given pH in standard buffer systems and validated the sorting result with LC/MS. Furthermore, we coupled two sorting steps via off-chip titration and isolated peptides within specific pI ranges from sample mixtures, where the pI range was simply set by the pH values of the buffer solutions. This free-flow zone electrophoresis sorting device, with its simplicity of fabrication, and a sorting resolution of 0.5 pH unit, can potentially be a high-throughput sample fractionation tool for targeted proteomics using LC/MS.
