Rig-space physics (2012)

We present a method that brings the benefits of physics-based simulations to traditional animation pipelines. We formulate the equations of motions in the subspace of deformations defined by an animator's rig. Our framework fits seamlessly into the workflow typically employed by artists, as our output consists of animation curves that are identical in nature to the result of manual keyframing. Artists can therefore explore the full spectrum between handcrafted animation and unrestricted physical simulation. To enhance the artist's control, we provide a method that transforms stiffness values defined on rig parameters to a non-homogeneous distribution of material parameters for the underlying FEM model. In addition, we use automatically extracted high-level rig parameters to intuitively edit the results of our simulations, and also to speed up computation. To demonstrate the effectiveness of our method, we create compelling results by adding rich physical motions to coarse input animations. In the absence of artist input, we create realistic passive motion directly in rig space.
Mobile LiDAR-Based Convergence Detection in Underground Tunnel Environments (2017)

This paper presents a mobile LiDAR-based method for remotely identifying convergence (i.e., naturally occurring deformation) in excavated underground tunnel environments. A mobile LiDAR system is used to collect and generate two independent 3D point clouds of the excavated environment. In the absence of actual convergence, simulated deformation is applied to one of the two point clouds based on a simple convergence model. Registration of the 3D data is performed by using a rough alignment based on principal components, followed by a piecewise iterative closest point (ICP) algorithm. The residual point-to-surface distances are then used as a deformation signal, which is filtered using a modal analysis based on expected deformation shapes as well as a median filter. It was found that convergence deformations of 0.05 m could be confidently identified and deformations as low as 0.0125 m could be detected within residual deformation data with a mean absolute error of approximately 0.0235 m. The proposed technique therefore allows deformations on the same order as background noise to be characterized and flagged for further inspection by mine operators.
The correlation between inter-modulation distortion of GaAs MESFETs and ungated recess width (1999)

Inter-modulation distortion of GaAs MESFET discrete and MMIC PA devices was found to be effected by the width of the ungated recess. Devices with ungated recess width in excess of 105 nm exhibit soft gain compression and out-of-spec inter-modulation performance. Degraded linearity is manifested in worse IM3 and significantly different IM5 dependence on the output power, whereas soft gain compression leads to premature power saturation, smaller power gain and power-added efficiency. Good correlation between the loadpull results, waveform measurements and 2-stage linear power amplifier performance data was obtained. This work provides insight into a critical device parameter for optimum performance of high linearity amplifier applications.
Distortion cancellation precoding for OFDM-SDMA downlink with nonlinear power amplifiers (2015)

In this work we consider an OFDM-SDMA downlink with a real life, nonlinear Power Amplifier (PA). It is well known that a nonlinear PA produces nonlinear distortions. We propose a novel iterative algorithm based on Zero Forcing (ZF) precoding to cancel the nonlinear distortions seen at the mobile devices while preserving the interference-free reception due to ZF. The proposed algorithm also keeps the out-of-band radiation of the transmitted signals low, in order to satisfy spectral purity requirements. For a low Back-Off (BO) scenario, where the nonlinear distortions are strong, the proposed algorithm shows a much lower Symbol Error Rate (SER) and much higher power efficiency than the well known ZF-SDMA with a real life PA.
Super-Stable Energy Based Switching Control Scheme for DC-DC Buck Converter Circuits (2005)

This paper has proposed a new energy based switching scheme for controlling DC-DC buck converter circuits and analysed its stability. There are three modes of operations, and the switching among these three modes depends on the reference voltage and the inductor reference current. The inductor reference current is calculated by the principle of energy balance. The reference voltage is designed to ensure that the voltage ripple as well as average value of the output voltage remain approximately constant in response to line and load disturbances. The phase plane analysis and sensitivity matrix analysis show that the proposed control scheme is free from chaos and in fact has a super-stable orbit.
Controllable corrugation of chemically converted graphene sheets in water and potential application for nanofiltration (2011)

A combination of AFM, SEM and permeation experiments suggests that the amplitude of corrugation of chemically converted graphene (CCG) sheets in water can be readily controlled by hydrothermal treatment, leading to a new class of permeation-tuneable nanofiltration membranes.
Individualized Mutual Adaptation in Human-Agent Teams (2021)

The ability to collaborate with previously unseen human teammates is crucial for artificial agents to be effective in human-agent teams (HATs). Due to individual differences and complex team dynamics, it is hard to develop a single agent policy to match all potential teammates. In this article, we study both human-human and HAT in a dyadic cooperative task, Team Space Fortress. Results show that the team performance is influenced by both players’ individual skill level and their ability to collaborate with different teammates by adopting complementary policies. Based on human-human team results, we propose an adaptive agent that identifies different human policies and assigns a complementary partner policy to optimize team performance. The adaptation method relies on a novel similarity metric to infer human policy and then selects the most complementary policy from a pretrained library of exemplar policies. We conducted human-agent experiments to evaluate the adaptive agent and examine mutual adaptation in HAT. Results show that both human adaptation and agent adaptation contribute to team performance.
Shift Work and Obesity among Canadian Women: A Cross-Sectional Study Using a Novel Exposure Assessment Tool (2015)

As these analyses found a positive association between high probability of shift work exposure and obesity in a population-based sample, but not in an alumni cohort, it is suggested that the relationship between shift work and obesity is complex, and may be particularly susceptible to occupational and education-related factors within a given population.

Optimizing aesthetic results in skin grafting. (2012)

The aesthetic goal in skin grafting is to provide a cosmetically pleasing coverage of soft tissue defects while minimizing donor site morbidity. A skin graft should blend well with the color and texture of the surrounding skin, reduce wound size, and not interfere with the function of the reconstructed part. This review examines the key components of choosing the appropriate donor skin for a variety of defects. The decision-making process is based on the anatomic location of the defect; donor site availability; and graft size, thickness, and pigmentation. The aesthetic implications of using a sheet graft versus a meshed graft versus an expanded graft are discussed. Aside from addressing the aesthetic needs of the defect, attention is paid to the functional goals of the reconstructed part and reduced donor site morbidity. Partial graft failure can have significant deleterious effects on the aesthetic outcome of skin grafts. The need for further grafting or healing by secondary intention may result in additional scarring and deformity. Recommendations for improvement in graft take and infection control are presented.

Coronary artery imaging with intravascular high-frequency ultrasound. (1990)

Safe and effective clinical application of new interventional therapies may require more precise imaging of atherosclerotic coronary arteries. To determine the reliability of catheter-based intravascular ultrasound as an imaging modality, a miniaturized prototype ultrasound system (1-mm transducer; center frequency, 25 MHz) was used to acquire two-dimensional, cross-sectional images in 21 human coronary arteries from 13 patients studied at necropsy who had moderate-to-severe atherosclerosis. Fifty-four atherosclerotic sites imagined by ultrasound were compared with formalin-fixed and fresh histological sections of the coronary arteries with a digital video planimetry system. Ultrasound and histological measurements correlated significantly (all p less than 0.0001) for coronary artery cross-sectional area (r = 0.94), residual lumen cross-sectional area (r = 0.85), percent cross-sectional area (r = 0.84), and linear wall thickness (plaque and media) measured at 0 degrees, 90 degrees, 180 degrees, and 270 degrees (r = 0.92). Moreover, ultrasound accurately predicted histological plaque composition in 96% of cases. Anatomic features of the coronary arteries that were easily discernible were the lumen-plaque and media-adventitia interfaces, very bright echoes casting acoustic shadows in calcified plaques, bright and homogeneous echoes in fibrous plaques, and relatively echo-lucent images in lipid-filled lesions. These data indicate that intravascular ultrasound provides accurate image characterization of the artery lumen and wall geometry as well as the presence, distribution, and histological type of atherosclerotic plaque. Thus, ultrasound imaging appears to have great potential application for enhanced diagnosis of coronary atherosclerosis and may serve to guide new catheter-based techniques in the treatment of coronary artery disease.
Acoustic Detection of Rail Car Roller Bearing Defects: Phase III, System Evaluation Test (2003)

In July 1999, Transportation Technology Center, Inc. (TTCI), a subsidiary of the Association of American Railroads (AAR), conducted a system evaluation test as part of the Federal Railroad Administration’s (FRA) Improved Freight Car Roller Bearing Inspection Program (Task Order 122), at the Transportation Technology Center, Pueblo, Colorado. It included a series of simulated revenue service tests using a consist of eight railcars that contained wheelsets with both good bearings and specific roller bearing defects. The purpose of these tests was the evaluation of improved wayside acoustic bearing detection systems. TTCI was the only supplier of a prototype acoustic bearing detector system for evaluation -- although several other suppliers participated by collecting onboard or wayside data, which may lead to other developments. The acoustic bearing detector was developed as part of AAR’s Track Performance Monitoring Strategic Initiative funded by AAR member railroads.

A comparison of the classical and modified forms of the continuity equation in the On-X prosthetic heart valve in the aortic position. (2000)

The modified continuity equation based on the peak velocity ratio does not give the same result as the classical formula based on the velocity-time ratio. The modified method cannot reliably be substituted for the classical method in normally functioning On-X valves.
Cloning and characterization of an alternative splicing transcript of the gene coding for human cytidine deaminase (2007)

Human cytidine deaminase (HCD) catalyzes the deamination of cytidine or deoxycytidine to uridine or deoxyuridine, respectively. The genomic sequence of HCD is formed by 31 kb with 4 exons and several alternative splicing signals, but an alternative form of HCD has yet to be reported. Here we describe the cloning and characterization of a small form of HCD, HSCD, and it is likely to be a product of alternative splicing of HCD. The alignment of DNA sequences shows that the HSCD matches HCD in 2 parts, except for a deletion of 170 bp. Based on the HCD genome organization, exons 1 and 4 should be joined and all sequences of introns and exons 2 and 3 should be deleted by splicing. This alternative splicing shifted the translation of the reading frame from the point of splicing. The estimated molecular mass is 9.8 kDa, and this value was confirmed by Western blot and mass spectroscopy after expressing the gene fused with glutathionine-S-transferase in the pGEX vector. The deletion and shift of the reading frame caused a loss of HCD activity, which was confirmed by enzyme assay and also with NIH3T3 cells modified to express HSCD and challenged against cytosine arabinoside. In this work we describe the identification and characterization of HSCD, which is the product of alternative splicing of the HCD gene.
EVOLUTION OF FLAVORS AND SCENTS (2005)

The world is filled with flavors and scents, which are the result of volatile compounds produced and emitted by plants. These specialized metabolites are the products of specific metabolic pathways. The terpenoid, fatty acid, and phenylpropanoid pathways contribute greatly to production of volatile compounds. Mechanisms that lead to evolution of volatile production in plants include gene duplication and divergence, convergent evolution, repeated evolution, and alteration of gene expression, caused by a number of factors, followed by change in enzyme specificity. Many examples of these processes are now available for three important gene families involved in production of volatile metabolites: the small molecule O-methyltransferases, the acyltransferases, and the terpene synthases. Examples of these processes in these gene families are found in roses, Clarkia breweri, and sweet basil, among others. Finally, evolution of volatile emission will be an exciting field of study for the foreseeable future.

Demonstration of the angular uncertainty principle for single photons (2011)

We present an experimental demonstration of a form of the angular uncertainty principle for single photons. Producing light from type I down-conversion, we use spatial light modulators to perform measurements on signal and idler photons. By measuring states in the angle and orbital angular momentum basis, we demonstrate the uncertainty relation of Franke-Arnold et al (2004 New J. Phys. 6 103). We consider two manifestations of the uncertainty relation. In the first we herald the presence of a photon by detection of its paired partner and demonstrate the uncertainty relation on this single photon. In the second, we perform orbital angular momentum measurements on one photon and angular measurements on its correlated partner exploring, in this way, the uncertainty relation through non-local measurements.
Single bump, two-color quantum dot camera (2007)

The authors report a two-color, colocated quantum dot based imaging system used to take multicolor images using a single focal plane array (FPA). The dots-in-a-well (DWELL) detectors consist of an active region composed of InAs quantum dots embedded in In.15Ga.85As quantum wells. DWELL samples were grown using molecular beam epitaxy and fabricated into 320×256 focal plane arrays with indium bumps. The FPA was then hybridized to an Indigo ISC9705 readout circuit and tested. Calibrated blackbody measurements at a device temperature of 77K yield midwave infrared and long wave infrared noise equivalent difference in temperature of ∼55 and 70mK.
Fuzzy joins in MapReduce: Edit and Jaccard distance (2016)

In ICDE'12, Afrati, Das Sarma, Menestrina, Parameswaran and Ullman proposed similarity join algorithms for MapReduce. In this paper, we evaluate and extend their research, testing their proposed algorithms using edit distance and Jaccard similarity. We provide details of adaptations needed to implement their algorithms based on these similarity measures. We conduct an extensive experimental study on large datasets and evaluate the algorithms across several dimensions that define the performance profile in MapReduce.
Efficient preimage computation using a novel success-driven ATPG (2003)

Preimage computation is a key step in formal verification. Pure OBDD-based symbolic method is vulnerable to the space-explosion problem. On the other hand, conventional ATPG/SAT-based method can handle large designs but can suffer from time explosion. Unlike methods that combine ATPG/SAT and OBDD, we present a novel success-driven learning algorithm which significantly accelerates an ATPG engine for enumerating all solutions (preimages). The algorithm effectively prunes redundant search space due to overlapped solutions and constructs a free BDD on the fly so that it becomes the representation of the preimage set at the end. Experimental results have demonstrated the effectiveness of the approach, in which we are able to compute preimages for large sequential circuits, where OBDD-based methods fail.

Data from Targeting eIF4A-Dependent Translation of KRAS Signaling Molecules (2023)

&lt;div&gt;Abstract&lt;p&gt;Pancreatic adenocarcinoma (PDAC) epitomizes a deadly cancer driven by abnormal KRAS signaling. Here, we show that the eIF4A RNA helicase is required for translation of key KRAS signaling molecules and that pharmacological inhibition of eIF4A has single-agent activity against murine and human PDAC models at safe dose levels. EIF4A was uniquely required for the translation of mRNAs with long and highly structured 5′ untranslated regions, including those with multiple G-quadruplex elements. Computational analyses identified these features in mRNAs encoding KRAS and key downstream molecules. Transcriptome-scale ribosome footprinting accurately identified eIF4A-dependent mRNAs in PDAC, including critical KRAS signaling molecules such as PI3K, RALA, RAC2, MET, MYC, and YAP1. These findings contrast with a recent study that relied on an older method, polysome fractionation, and implicated redox-related genes as eIF4A clients. Together, our findings highlight the power of ribosome footprinting in conjunction with deep RNA sequencing in accurately decoding translational control mechanisms and define the therapeutic mechanism of eIF4A inhibitors in PDAC.&lt;/p&gt;Significance:&lt;p&gt;These findings document the coordinate, eIF4A-dependent translation of RAS-related oncogenic signaling molecules and demonstrate therapeutic efficacy of eIF4A blockade in pancreatic adenocarcinoma.&lt;/p&gt;&lt;/div&gt;
