A Novel Quality Assessment Method forFlat Panel Display Defects (2015)

This paper presents a novel quality assessment method for flat panel display (FPD) defects, often called Muras, that employs the characteristics of the human visual system (HVS). Given a Mura image, the brightness difference between the Mura and its surrounding region is first adjusted to reflect the HVS's property of background-adaptive perception. Then, the resulting adjusted Mura image is further processed using multiscale defect saliency acquisition (MDSA) to obtain a final Mura image with human perception characteristics. In the experiments, the quality scores of Mura test images are measured using the conventional and proposed methods. The results demonstrate that the quality of Mura evaluated by the proposed method correlates with the subjective quality to a much higher degree compared with the conventional methods.
Robust real-time visual odometry for dense RGB-D mapping (2013)

This paper describes extensions to the Kintinuous [1] algorithm for spatially extended KinectFusion, incorporating the following additions: (i) the integration of multiple 6DOF camera odometry estimation methods for robust tracking; (ii) a novel GPU-based implementation of an existing dense RGB-D visual odometry algorithm; (iii) advanced fused realtime surface coloring. These extensions are validated with extensive experimental results, both quantitative and qualitative, demonstrating the ability to build dense fully colored models of spatially extended environments for robotics and virtual reality applications while remaining robust against scenes with challenging sets of geometric and visual features.
Radiologic placement of peritoneal dialysis catheters: preliminary experience. (1992)

The authors percutaneously placed 45 catheters for peritoneal dialysis in 32 patients, aged 31-83 years, in a radiology department. In all patients, the procedure was modified by use of the Hawkins needle, and in response to the high frequency of extrusion of the proximal cuff, the deep cuff of the 16th and each subsequent catheter was sutured to the rectus muscle or fascia. After 17 catheters were placed, the catheter was modified with a permanent bend, or "U" neck, between the two cuffs, which were then thickened. All procedures were performed with use of local anesthesia, and all catheters were successfully placed. Acute complications included bowel perforation associated with peritonitis in one patient (2%). Delayed complications included cuff extrusion in nine patients (20%), obstruction in nine patients (20%), and peritonitis requiring removal of the catheter in three patients (7%). This study shows the feasibility of percutaneous placement of peritoneal dialysis catheters by radiologists despite the need for improved technique and equipment.
Optimizing the Latent Space of Generative Networks (2018)

Generative Adversarial Networks (GANs) have achieved remarkable results in the task of generating realistic natural images. In most successful applications, GAN models share two common aspects: solving a challenging saddle point optimization problem, interpreted as an adversarial game between a generator and a discriminator functions; and parameterizing the generator and the discriminator as deep convolutional neural networks. The goal of this paper is to disentangle the contribution of these two factors to the success of GANs. In particular, we introduce Generative Latent Optimization (GLO), a framework to train deep convolutional generators using simple reconstruction losses. Throughout a variety of experiments, we show that GLO enjoys many of the desirable properties of GANs: synthesizing visually-appealing samples, interpolating meaningfully between samples, and performing linear arithmetic with noise vectors; all of this without the adversarial optimization scheme.
Fracture testing and performance of beryllium copper alloy C17510 (1994)

When a literature search and discussion with manufacturers revealed that there was virtually no existing data related to the fracture properties and behavior of copper beryllium alloy C17510, a series of test programs was undertaken to ascertain this information for several variations in material processing and chemistry. These variations in C17510 were primarily optimized for combinations of strength and conductivity. While originally intended for use as cyclically loaded high-field, high-strength conductors in fusion energy research, material testing of C17510 has indicated that it is an attractive and economical alternative for a host of other structural, mechanical and electrical applications. ASTM tests performed on three variations of C17510 alloys included both J-integral and plane strain fracture toughness testing and fatigue crack growth rate tests, as well as verifying tensile, hardness, Charpy, and other well defined mechanical properties. Fracture testing was performed at both room and liquid nitrogen temperatures, which bound the thermal environment anticipated for the fusion components being designed. Fatigue crack propagation stress ratios ranged from nominal zero to minus one at each temperature. In order to confirm the test results, duplicate and independent test programs were awarded to separate facilities with appropriate test experience, whenever possible. The primary goal of the test program, to determine and bound the fracture toughness and Paris constants for C17510,was accomplished. In addition, a wealth of information was accumulated pertaining to crack growth characteristics, effects of directionality and potential testing pitfalls. The paper discusses the test program and its findings in detail.
Keep CALM and Explore: Language Models for Action Generation in Text-based Games (2020)

Text-based games present a unique challenge for autonomous agents to operate in natural language and handle enormous action spaces. In this paper, we propose the Contextual Action Language Model (CALM) to generate a compact set of action candidates at each game state. Our key insight is to train language models on human gameplay, where people demonstrate linguistic priors and a general game sense for promising actions conditioned on game history. We combine CALM with a reinforcement learning agent which re-ranks the generated action candidates to maximize in-game rewards. We evaluate our approach using the Jericho benchmark, on games unseen by CALM during training. Our method obtains a 69% relative improvement in average game score over the previous state-of-the-art model. Surprisingly, on half of these games, CALM is competitive with or better than other models that have access to ground truth admissible actions. Code and data are available at https://github.com/princeton-nlp/calm-textgame.
Cardiac action potential repolarization revisited: early repolarization shows all‐or‐none behaviour (2017)

In healthy mammalian hearts the action potential (AP) waveform initiates and modulates each contraction, or heartbeat. As a result, AP height and duration are key physiological variables. In addition, rate-dependent changes in ventricular AP duration (APD), and variations in APD at a fixed heart rate are both reliable biomarkers of electrophysiological stability. Present guidelines for the likelihood that candidate drugs will increase arrhythmias rely on small changes in APD and Q-T intervals as criteria for safety pharmacology decisions. However, both of these measurements correspond to the final repolarization of the AP. Emerging clinical evidence draws attention to the early repolarization phase of the action potential (and the J-wave of the ECG) as an additional important biomarker for arrhythmogenesis. Here we provide a mechanistic background to this early repolarization syndrome by summarizing the evidence that both the initial depolarization and repolarization phases of the cardiac action potential can exhibit distinct time- and voltage-dependent thresholds, and also demonstrating that both can show regenerative all-or-none behaviour. An important consequence of this is that not all of the dynamics of action potential repolarization in human ventricle can be captured by data from single myocytes when these results are expressed as 'repolarization reserve'. For example, the complex pattern of cell-to-cell current flow that is responsible for AP conduction (propagation) within the mammalian myocardium can change APD and the Q-T interval of the electrocardiogram alter APD stability, and modulate responsiveness to pharmacological agents (such as Class III anti-arrhythmic drugs).
Neural Outlier Rejection for Self-Supervised Keypoint Learning (2019)

Identifying salient points in images is a crucial component for visual odometry, Structure-from-Motion or SLAM algorithms. Recently, several learned keypoint methods have demonstrated compelling performance on challenging benchmarks. However, generating consistent and accurate training data for interest-point detection in natural images still remains challenging, especially for human annotators. We introduce IO-Net (i.e. InlierOutlierNet), a novel proxy task for the self-supervision of keypoint detection, description and matching. By making the sampling of inlier-outlier sets from point-pair correspondences fully differentiable within the keypoint learning framework, we show that are able to simultaneously self-supervise keypoint description and improve keypoint matching. Second, we introduce KeyPointNet, a keypoint-network architecture that is especially amenable to robust keypoint detection and description. We design the network to allow local keypoint aggregation to avoid artifacts due to spatial discretizations commonly used for this task, and we improve fine-grained keypoint descriptor performance by taking advantage of efficient sub-pixel convolutions to upsample the descriptor feature-maps to a higher operating resolution. Through extensive experiments and ablative analysis, we show that the proposed self-supervised keypoint learning method greatly improves the quality of feature matching and homography estimation on challenging benchmarks over the state-of-the-art.
CORDS multidatabase project: research and prototype overview (1993)

One of the data services offered within the CORDS Service Environment is a multidatabase. Fulfilling this service requirement is the man date of the CORDS Multidatabase project involving researchers at the University of Waterloo and Queen's University. One objective of this project is to research issues in multidatabase systems. Thus far these include schema integration, (global) query decomposition and optimization, and distributed transaction management. A second objective is to design and implement a multidatabase prototype. The latter objective presented an opportunity to explore and assess a number of international and industry standards: for example, Microsoft's Open Database Connectivity (oDBC) and the Open Software Foundation's Distributed Computing Environment (OSF/DCE).This paper discusses the overall design of the multidatabase, the research issues addressed, and the status of the prototype implementation.
Low complexity FIR filters using factorization of perturbed coefficients (2002)

This paper presents a factorization based technique to reduce the computational complexity of implementing Finite Impulse Response (FIR) digital filters. It is possible to design FIR filters in which all of the filter coefficients are products of the first seven prime numbers. For such filters, factorization of the filter coefficients allows the reuse of intermediate results among computations involving common factors. Since the coefficients are products of only small prime numbers, it is also possible to generate each of the partial products with a single shift and add operation. Compared to a traditional implementation, this results in a 35-50% reduction in computational complexity, which is shown to translate into lower power consumption.

Auf Grundlage des bisher unbeschriebenen Dibenzo‐9a‐azaphenalens (DBAPhen) als molekularer Baustein wird ein allgemein anwendbares Konzept zur Synthese ausgedehnter Nanographene und Nanographenstreifen mit Stickstoff‐dotierten Zickzackkanten eingeführt.
Reconfigurable SCM Capacity Identification Method for SCM/NAND Flash Hybrid Disaggregated Storage (2017)

This paper proposes a methodology to identify the reconfigurable storage class memory (SCM) capacity for disaggregated storage with SCM/NAND flash memory. In the disaggregated storage, various kinds of applications are processed simultaneously. SCM improves performance of NAND flash based storage, but only limited capacity of SCM can be added due to SCM's high cost. In the proposed disaggregated storage, an application analysis method classifies applications, and identify the optimal SCM capacity for each application. To determine the type of application, a new characteristic "magnification" is defined. The magnification considers effective capacity of SCM because data eviction operation from SCM to NAND flash is triggered when SCM usage reaches a predetermined threshold capacity. The application is classified into four types by the magnification. Type 1 application has a sharp peak in its magnification shape. Compared with Type 1, Type 2 application has a gentler peak. The optimal SCM capacity for Type 1 and Type 2 applications can be identified when the magnification values reach their peak. Type 3 application, in which the magnification decreases with large SCM capacity, requires an additional analysis of the access frequency. The optimal SCM capacity is identified by the logical block address (LBA) space accessed before. Finally, because Type 4 application has 10 or less of the maximum value of magnification, SCM is not required.

Complete genome sequence of simian adenovirus 1: an Old World monkey adenovirus with two fiber genes (2005)

Simian adenovirus 1 (SAdV-1) is one of many adenovirus strains that were isolated from Old World monkey cells during poliomyelitis vaccine production several decades ago. Despite the availability of these viruses, knowledge of their genetic content and phylogeny is rudimentary. In the present study, the genome sequence of SAdV-1 (34,450 bp) was determined and analysed. In regions where genetic content varies between primate adenoviruses, SAdV-1 has a single virus-associated RNA gene, six genes in each of the E3 and E4 regions and two fiber genes. SAdV-1 clusters phylogenetically with HAdV-40, a member of human adenovirus species HAdV-F, which also has two fiber genes. However, based on phylogenetic distances and other taxonomic criteria, SAdV-1 is proposed to represent a novel adenovirus species.

Utilization effects of Rx-OTC switches and implications for future switches (2013)

We examined the effect of over-the-counter (OTC) conversion of prescription drugs on utilization at the drug class level using monthly drug utilization data from the US for the period 1999-2010 for 9 drug classes: antihistamines, benign prostatic hyperplasia medication, cholesterol control drugs (statins), analgesics (triptans), contraception medications (emergency contraception), antiulcerants (proton pump inhibitors) non-sedating antihistamines, weight-loss remedies and erectile dysfunction remedies. We performed interrupted time series analysis to detect a break in the trend of drug utilization following OTC introduction. We found that the introduction of the first OTC drug increased drug utilization at the class level by an average of 30% or more. We concluded that OTC switches can be an important policy tool for improving public health in drug classes where a significant proportion of the population is untreated and where consumers can effectively manage treatment with limited physician supervision.
Oxidative Capacity of Nanobubbles and Its Effect on Seed Germination (2015)

Nanobubbles (NBs) have been reported to be effective at accelerating the metabolism of living organisms, but the mechanism is not yet well understood. In this study, the production of reactive oxygen species (ROS) by NBs and its effect on seed germinations were investigated. The fluorescence response of APF to NB water was measured. It changed depending on the NB number density which decreased with storage time. This indicated that NBs could produce ROS and the amount of ROS had positive correlation with the NB number density. The fluorescence intensity of APF increases linearly with the concentration of H2O2 in the range of 0–1 mM. Just after the NB generation, the oxidative capacities represented by amount of ROS of oxygen NB water and gas-mixture (air + nitrogen) NB water were estimated to be equivalent to 0.5 and 0.3 mM H2O2 respectively. The seed germination tests were performed in the NB water, distilled water and H2O2 solutions. The germination rate at each observation times of seeds submerged in gas-mixture NB water and 0.3 mM H2O2 solutions were both higher than those submerged in distilled water. The amounts of superoxide radicals in the seeds were detected using NBT staining. The results of absorbance data proved that the amounts of O2•– in seeds submerged in gas-mixture NB water and in 0.3 mM H2O2 solution were similar and significantly higher than those in the distilled water. These results indicated that moderate level of exogenous ROS produced by NB water played an important role in seed germination.
[Effect of path-length variations on PLSR calibration model in noninvasive measurement of blood glucose by mid-infrared spectroscopy]. (2012)

In noninvasive blood glucose measurement, it is difficult to keep the contact area between skin and internal reflectance element uniform while the mid-infrared spectra of human skin are taken, and this would lead to path-length variations. To study the effect of path-length variations on PLSR calibration model, in the present paper, according to the correlation coefficients between path-lengths and glucose concentrations, two PLSR models were achieved respectively and RMSECV were 31.3 and 4.52 mg x dL(-1), RMSEP were 30.3 and 98.7 mg x dL(-1) for the validation set. The results show that the chance correlations between path-lengths and glucose concentrations will lead to calibration models with different accuracy and robustness. This is useful to improving the reliability of noninvasive measurement of blood glucose by mid-infrared spectroscopy.

An Evaluation of Oracle's StillImage Plugin as a Platform for Dynamic Image Search (2015)

In this project, we look at some different off­-the­-shelf solutions for creating an image search engine that, given an unknown cover for a comic book, would return relevant information about a matching comic book in the database. The project first examines some alternative tools available to developers to do image search and comparison, and then looks at Oracle's solution for image comparison, Still Image. A prototype search is built to test Oracle's capabilities and is evaluated on speed and quality of results. In the end, Oracle is determined to be a useful tool for storing and comparing images, but is still not capable of searching for an image in a reasonable amount of time.
