A Practical Laser Projector with New Illumination Optics for Reduction of Speckle Noise (2004)

We have developed illumination optics for image projection systems. It realizes uniform illumination and suppression of speckle and diffraction noises by using a diffuser and integrator optics. By optimizing the diffusing angle of the diffuser, optical power loss was less than 10%. A proto type of a laser projector with a red wide-stripe semiconductor laser and green and blue second-harmonic generation lasers was realized by using the developed illumination optics and twisted nematic liquid-crystal panels. Still images from a personal computer and video images from a digital versatile disk (DVD) player were displayed with the system and a wide colour gamut and smooth images without diffraction noise nor speckle noise were confirmed.
Fault Localization for Dynamic Web Applications (2011)

In recent years, there has been significant interest in fault-localization techniques that are based on statistical analysis of program constructs executed by passing and failing executions. This paper shows how the Tarantula, Ochiai, and Jaccard fault-localization algorithms can be enhanced to localize faults effectively in web applications written in PHP by using an extended domain for conditional and function-call statements and by using a source mapping. We also propose several novel test-generation strategies that are geared toward producing test suites that have maximal fault-localization effectiveness. We implemented various fault-localization techniques and test-generation strategies in Apollo, and evaluated them on several open-source PHP applications. Our results indicate that a variant of the Ochiai algorithm that includes all our enhancements localizes 87.8 percent of all faults to within 1 percent of all executed statements, compared to only 37.4 percent for the unenhanced Ochiai algorithm. We also found that all the test-generation strategies that we considered are capable of generating test suites with maximal fault-localization effectiveness when given an infinite time budget for test generation. However, on average, a directed strategy based on path-constraint similarity achieves this maximal effectiveness after generating only 6.5 tests, compared to 46.8 tests for an undirected test-generation strategy.

Achromatic Interferometric Subtraction of Optical Fields (2019)

In absorption spectroscopy, the absorption of a sample manifests as a change of the radiation source intensity. This imposes two main limitations on detection sensitivity: Firstly, the smallest detectable signal is lower-bound by excess source noise. Secondly, resolving small changes of a comparatively large signal requires high-dynamic-range detection. Previous work in the field of dual-beam Fourier transform infrared spectroscopy [1] successfully suppressed excess source noise by measuring the combined interferogram and anti-interferogram. However, the resulting strong constant background still required high-dynamic-range detection and digitization.
Three-Dimensional Microwave Breast Imaging: Dispersive Dielectric Properties Estimation Using Patient-Specific Basis Functions (2009)

Breast imaging via microwave tomography involves estimating the distribution of dielectric properties within the patient's breast on a discrete mesh. The number of unknowns in the discrete mesh can be very large for 3-D imaging, and this results in computational challenges. We propose a new approach where the discrete mesh is replaced with a relatively small number of smooth basis functions. The dimension of the tomography problem is reduced by estimating the coefficients of the basis functions instead of the dielectric properties at each element in the discrete mesh. The basis functions are constructed using knowledge of the location of the breast surface. The number of functions used in the basis can be varied to balance resolution and computational complexity. The reduced dimension of the inverse problem enables application of a computationally efficient, multiple-frequency inverse scattering algorithm in 3-D. The efficacy of the proposed approach is verified using two 3-D anatomically realistic numerical breast phantoms. It is shown for the case of single-frequency microwave tomography that the imaging accuracy is comparable to that obtained when the original discrete mesh is used, despite the reduction of the dimension of the inverse problem. Results are also shown for a multiple-frequency algorithm where it is computationally challenging to use the original discrete mesh.

Targeting Protein Tyrosine Phosphatases for Anticancer Drug Discovery (2010)

Protein tyrosine phosphatases (PTPs) are a diverse family of enzymes encoded by 107 genes in the human genome. Together with protein tyrosine kinases (PTKs), PTPs regulate various cellular activities essential for the initiation and maintenance of malignant phenotypes. While PTK inhibitors are now used routinely for cancer treatment, the PTP inhibitor development field is still in the discovery phase. In this article, the suitability of targeting PTPs for novel anticancer drug discovery is discussed. Examples are presented for PTPs that have been targeted for anticancer drug discovery as well as potential new PTP targets for novel anticancer drug discovery.
StorNet: Co-scheduling of end-to-end bandwidth reservation on storage and network systems for high-performance data transfers (2011)

Modern scientific data-intensive applications brought about the need for novel data transfer technologies and automated tools capable of effectively utilizing available raw network bandwidth and intelligently assisting scientists in replicating large volumes of data to desired locations in a timely manner. In this paper we describe the design of StorNet, an integrated end-to-end resource provisioning and management system for high performance data transfers that can operate with heterogeneous network protocols and storage systems in a federated computing environment. StorNet allocates and co-schedules storage and network resources involved in data transfers. It is based on existing Storage Resource Manager, TeraPaths, and OSCARS capabilities. StorNet provides data intensive applications with the capability of predictable, yet efficient delivery of data at rates of multiple gigabits/second, bridging end-to-end advanced storage and network technologies in a transparent way.
Model Dip-guided Imaging Condition for Reverse-time Migration in VSP Scenario (2012)

We propose a new imaging condition aimed at eliminating swing artifacts, and also balancing the amplitude of the migrated features in RTM images with particular application to VSP data. It uses both the Umov-Poynting vector-based obliquity filter and a model-guided dip filter with several control parameters having a clear physical sense and permits the suppression of imaging artifacts. The quality and improvement of VSP images are demonstrated with two realistic synthetic data examples.
An optical fiber infrasound sensor (2002)

A new sensor for detecting infrasonic signals from distant sources has been designed, tested, and deployed. The instrument consists of a long (of order 100 m), compliant, tubular diaphragm tightly wrapped with optical fibers. The air-filled diaphragm is sealed from the ambient atmosphere and therefore expands and contracts radially along its length as the pressure changes. An optical system monitors minute variations in the optical path length of the fibers, which change as the tube expands and contracts. The new instrument responds to the spatially integrated pressure average along its length. As it relies on optical interferometry, it does not suffer from the propagation delays inherent to mechanical noise filters and as a result can be made very long. Above 1 Hz, the optical fiber infrasound sensor (OFIS) is less noisy than sensors relying on mechanical filters. The records collected from an 89 m long sensor indicate a new low noise limit in the band from 1 Hz to 10 Hz. Current research focuses on the relationship between sensor length and wind-induced noise, on the utility of the sensor as a directional infrasound antenna, and on the sensor’s performance at audio frequencies.
Discovery of Novel Central Nervous System Penetrant Metabotropic Glutamate Receptor Subtype 2 (mGlu<sub>2</sub>) Negative Allosteric Modulators (NAMs) Based on Functionalized Pyrazolo[1,5-<i>a</i>]pyrimidine-5-carboxamide and Thieno[3,2-<i>b</i>]pyridine-5-carboxamide Cores (2018)

A scaffold hopping exercise from a monocyclic mGlu<sub>2</sub> NAM with poor rodent PK led to two novel heterobicyclic series of mGlu<sub>2</sub> NAMs based on either a functionalized pyrazolo[1,5- a]pyrimidine-5-carboxamide core or a thieno[3,2- b]pyridine-5-carboxamide core. These novel analogues possess enhanced rodent PK, while also maintaining good mGlu<sub>2</sub> NAM potency, selectivity (versus mGlu<sub>3</sub> and the remaining six mGlu receptors), and high CNS penetration. Interestingly, SAR was divergent between the new 5,6-heterobicyclic systems.
Wide cross-species aminoacyl-tRNA synthetase replacement in vivo: yeast cytoplasmic alanine enzyme replaced by human polymyositis serum antigen. (1995)

Because of variations in tRNA sequences in evolution, tRNA synthetases either do not acylate their cognate tRNAs from other organisms or execute misacylations which can be deleterious in vivo. We report here the cloning and primary sequence of a 958-aa Saccharomyces cerevisiae alanyl-tRNA synthetase. The enzyme is a close homologue of the human and Escherichia coli enzymes, particularly in the region of the primary structure needed for aminoacylation of RNA duplex substrates based on alanine tRNA acceptor stems with a G3.U70 base pair. An ala1 disrupted allele demonstrated that the gene is essential and that, therefore, ALA1 encodes an enzyme required for cytoplasmic protein synthesis. Growth of cells harboring the ala1 disrupted allele was restored by a cDNA clone encoding human alanyl-tRNA synthetase, which is a serum antigen for many polymyositis-afflicted individuals. The human enzyme in extracts from rescued yeast was detected with autoimmune antibodies from a polymyositis patient. We conclude that, in spite of substantial differences between human and yeast tRNA sequences in evolution, strong conservation of the G3.U70 system of recognition is sufficient to yield accurate aminoacylation in vivo across wide species distances.

Graft-through Synthesis and Assembly of Janus Bottlebrush Polymers from A-<i>Branch</i>-B Diblock Macromonomers (2016)

We report the synthesis of Janus bottlebrush block copolymers by graft-through polymerization of branched diblock macromonomers. Self-assembly of the bottlebrushes was characterized by small-angle X-ray scattering, atomic force microscopy, and scanning electron microscopy. Phase separation and packing models of the bottlebrushes were computed, and their self-assembly behavior was corroborated experimentally in bulk and in thin films. Lamellar, hexagonal cylinder, and gyroid phases were observed and modeled. The A-branch-B Janus bottlebrush structure provides several unique advantages in the context of bottlebrush polymer assembly, including access to the first examples of gyroid phases.
A reduced complexity MIMO decoder (2015)

Multiple input and multiple output (MIMO) technique uses multiple antennas at the transmitter and the receiver to increase the data rate or the supported range. Orthogonal frequency division multiplexing (OFDM) is a multicarrier modulation technique used in MIMO systems. QR decomposition (QRD) is the first step in the decoding of the MIMO receiver. QR decomposition methods described by Gram Schmidt, Householder and Givens are computationally intensive as these involve division operations for normalization. The computation complexity of these methods for MIMO-OFDM systems makes it difficult to handle as the QR decomposition is performed for each subcarrier. In this paper, we propose modifications to QR decomposition for Householder's method, for reducing the computation complexity without affecting the system packet error rate (PER) performance. We show a comparison of basic and modified QRD methods in terms of computational complexity. Similar modifications can easily be performed with other QR decomposition methods to reduce their computational complexity. We will give packet error rate simulation results to show the usefulness of the method in real time for Wireless LAN systems based on IEEE 802.11ac standard. From the simulation results, it is apparent that the proposed methods works well for all frame formats and BW options of the IEEE 802.11ac standard.
Genome Introgression of <i>Festuca mairei</i> into <i>Lolium perenne</i> Detected by SSR and RAPD Markers (2003)

The genera of Lolium and Festuca belong to the same tribe Poeae, of subfamily Pooideae, but offer a range of complementary characteristics of agronomic importance. Intergeneric hybridization between the two genera is expected to combine the desirable characteristics of Lolium (good turf quality and good establishment) with Festuca species (drought and heat tolerance and disease resistance) in turfgrass breeding. The use of molecular markers to trace genome introgression in intergeneric hybrids has been reported for many crops, but not for Lolium and Festuca The objective of this study was to use simple sequence repeats (SSR) or microsatellite markers developed from Lolium perenne L. and random amplified polymorphic DNA (RAPD) markers to assess genomic introgression of Festuca mairei St. Yves (Fm) into L. perenne (Lp). Out of the 40 SSR markers tested, nine markers covering seven linkage groups, fully discriminated the Fm and Lp parents and revealed that the Fm genome was transferred into the backcross progenies of Fm and Lp. In 13 backcross derivatives detected by SSR markers, 11 individuals showed that the Fm genome was introduced. Forty‐one RAPD primers were chosen to detect genome introgression of the backcross progeny. A total of 188 parent‐specific markers were obtained. Ninety‐two (49%) are Fm‐specific markers. The 13 backcross progenies showed a range of introgression of Fm‐specific markers (5.4–60.9%). The introgression levels of the backcross progeny revealed by SSR and RAPD markers were significantly correlated ( P ≤ 0.0116). The SSRs and RAPD markers were informative and effective in detecting Fm genome introgression into the Lp genome.
Clinical validation of a real-time applicator position monitoring system for gynecologic intracavitary brachytherapy (2016)

Purpose: To validate the clinical feasibility and efficacy of a real-time applicator position monitoring system (RAPS) through a phantom study and a prospective clinical trial. Methods and materials: The RAPS measures the brachytherapy applicator displacement in real-time by computing the relative displacement between two infrared reflective targets, one attached to the applicator and the other to the patient's skin. A phantom study was performed to compare RAPS measurements with the ground truth. Six cervical cancer patients were enrolled in the clinical trial using MRI-based high-dose-rate brachytherapy with a Tandem-and-Ovoids applicator. The results from the RAPS are compared with the clinical method. Results: In the phantom study, an average difference between RAPS measurements and known displacements was 0.02 ± 0.01 mm in the superior-inferior direction, 0.02 ± 0.02 mm in the lateral direction, and 0.11 ± 0.06 mm in the anterior-posterior direction. In the clinical trial, the absolute difference in applicator displacement between the RAPS and the clinical method was 1.46 ± 1.13 mm. In all patient cases, a maximum applicator displacement of 6.66 mm (2.0 ± 1.5 mm) was observed using the RAPS. Conclusions: This work demonstrates the clinical efficacy of RAPS to measure applicator displacement.
Efficient MCMC sampling with implicit shape representations (2011)

We present a method for sampling from the posterior distribution of implicitly defined segmentations conditioned on the observed image. Segmentation is often formulated as an energy minimization or statistical inference problem in which either the optimal or most probable configuration is the goal. Exponentiating the negative energy functional provides a Bayesian interpretation in which the solutions are equivalent. Sampling methods enable evaluation of distribution properties that characterize the solution space via the computation of marginal event probabilities. We develop a Metropolis-Hastings sampling algorithm over level-sets which improves upon previous methods by allowing for topological changes while simultaneously decreasing computational times by orders of magnitude. An M-ary extension to the method is provided.
Coded modulation and precoding for electron-trapping optical memories (1998)

This paper develops coding and signal processing approaches for a novel optical recording channel that arises from electron-trapping phosphor materials. The recording medium allows multiple reads and writes, and one important feature is that the read process serves to erase the disk. This feature would enable vendors of prerecorded video to provide customers with one-time services. For applications where this feature is not desirable, the data can be immediately rewritten. From a communications viewpoint, the most important feature of this new channel is that, subject to a peak constraint, it supports a continuum of recording levels. The combination of read and write processes creates a partial-response channel, and the ability to write a continuum of levels makes it possible to employ precoding techniques, such as the one developed by Tomlinson (1971) and by Miyakawa and Harashima (1969). This is fundamentally different from magnetic data storage, where the read/write process creates a partial-response channel but where it is only possible to write two levels at the input to that channel. This paper shows that the use of precoding and coset codes can significantly improve upon the recording densities (and recording rates) that can be achieved by using M-ary run length constrained codes to eliminate intersymbol interference (ISI) at the output of the read/write process. The approach presented is applicable to any optical recording channel that supports a continuum of recording levels.
