Use of a VOC oxidation catalyst in the existing regenerative thermal oxidizers may greatly reduce fuel consumption and improve the oxidizer performance. This was demonstrated in a commercial 25,000 SCFM unit installed at a printing facility. The paper discusses the principles of the oxidizer retrofit design and test results obtained at various conditions of operation.
Simultaneous Monitoring of Frequency-dependent IQ Imbalances in a Dual-polarization IQ Modulator by using a Single Photodetector: A Phase Retrieval Approach (2021)

A low-complexity frequency-dependent IQ imbalance monitoring technique for a dual-polarization (DP) IQ modulator by using a single photodetector is proposed based on phase retrieval and demonstrated experimentally with a 63.25-Gbaud DP-16QAM signal.
(014) Impact of Vaginal Prasterone on the Rate of Urinary Tract Infections in GSM Patients and those on Aromatase Inhibitors: A Retrospective Cohort Analysis (2023)

Abstract Introduction The Genitourinary Syndrome of Menopause (GSM) is attributed to a decline in the levels of circulating sexual steroids which often results in increased vaginal pH, atrophic urogenital changes, elevated amount of post-void residual urine, and changes in the vaginal microbiome with a shift towards a predominance of fecal gram-negative bacteria rather than lactobacilli, which is believed to create a potential reservoir for recurrent urinary tract infections (UTIs). Current guidelines to prevent recurrent UTIs include vaginal estrogens. Intravaginal prasterone is converted locally in the vaginal tissue into androgens which are subsequently aromatised into estrogens. It is indicated to treat moderate to severe dyspareunia in postmenopausal women in the US. Objective The objective of this study was to assess, through real world evidence data, the potential of vaginal prasterone to be used in postmenopausal GSM women with recurrent UTIs as prophylaxis to reduce the future UTI risk. As a sensitivity analysis, women using aromatase inhibitors, medications that stop the production of estrogen in postmenopausal women typically prescribed to women with a history of breast cancer, were analyzed. Methods This retrospective matched-cohort study was conducted using the Integrated Dataverse (IDV®) - an open-source claims database from Symphony Health Solutions with data from February 2015 through January 2020. 22,245 women treated with prasterone for a minimum of 12 weeks were matched to women without any prescribed VVA-related treatment. Within each of these two groups, 286 matched patients were taking aromatase inhibitors. Results Across all age groups, women treated with prasterone have a significantly lower UTI prevalence compared to those untreated (6.58% and 12.3%, respectively; p˂0.0001). The highest difference in UTI prevalence among the prasterone treated and untreated women was observed in those aged 65-74 (7.15% and 16.2% respectively; p˂0.0001). Consistent with the above, among aromatase inhibitor users, women treated with prasterone have a significantly lower UTI prevalence (4.90% vs. 9.79%; p=0.008). Conclusions This study suggests that intravaginal prasterone may be a good candidate for prophylaxis in postmenopausal women with recurrent UTIs to reduce future UTI risk, including for patients taking aromatase inhibitors and having contraindications for estrogen-based therapies. This study is however based on real-world evidence and warrants further investigation in a prospective clinical setting.

Field-of-View IoU for Object Detection in 360° Images (2022)

360° cameras have gained popularity over the last few years. In this paper, we propose two fundamental techniques -- Field-of-View IoU (FoV-IoU) and 360Augmentation for object detection in 360° images. Although most object detection neural networks designed for the perspective images are applicable to 360° images in equirectangular projection (ERP) format, their performance deteriorates owing to the distortion in ERP images. Our method can be readily integrated with existing perspective object detectors and significantly improves the performance. The FoV-IoU computes the intersection-over-union of two Field-of-View bounding boxes in a spherical image which could be used for training, inference, and evaluation while 360Augmentation is a data augmentation technique specific to 360° object detection task which randomly rotates a spherical image and solves the bias due to the sphere-to-plane projection. We conduct extensive experiments on the 360indoor dataset with different types of perspective object detectors and show the consistent effectiveness of our method.
Asymptotic Cramer-Rao bounds for estimation of the parameters of damped sine waves in noise (1991)

The problem of estimating the parameters of a signal composed of several damped sine waves in noise has applications, for example, in transient signal analysis. Explicit, closed-form expressions are derived for the Cramer-Rao bound of this problem in the case of low damping, low spectral interference between the signal components, and a sufficiently large number of samples. Among several conclusions which are drawn from the expressions, it is found that the estimation problem is much more sensitive to errors in the damping factor and frequency than to errors in amplitude and phase.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Carbon nanotubes-zeolite complex: A Li-intercalated compound with high storage capacity (2004)

We report a composite system for Li intercalation, in which ultrasmall-diameter (4 Å) carbon nanotubes are confined inside the channels of nanoporous zeolite crystals. The first-principles pseudopotential calculations show that there are several possible sites for lithium to be intercalated, including the interior and exterior of the nanotubes. The vapor phase adsorption and electrochemical measurements both indicate that the lithium capacity of the system can be ∼10% by weight, which is higher than that of graphite intercalation compounds. The enhanced Li capacity makes the nanotubes-zeolite complex a plausible candidate for Li battery applications.

Multiple Fragment Docking and Linking in Primary and Secondary Pockets of Dopamine Receptors (2014)

A sequential docking methodology was applied to computationally predict starting points for fragment linking using the human dopamine D3 receptor crystal structure and a human dopamine D2 receptor homology model. Two focused fragment libraries were docked in the primary and secondary binding sites, and best fragment combinations were enumerated. Similar top scoring fragments were found for the primary site, while secondary site fragments were predicted to convey selectivity. Three linked compounds were synthesized that had 9-, 39-, and 55-fold selectivity in favor of D3 and the subtype selectivity of the compounds was assessed on a structural basis.
Dielectric Elastomer Actuators with Biphasic Ag–EGaIn Electrodes (2021)

A new electrode architecture for dielectric elastomer actuators (DEAs) is introduced in which a soft polyacrylate film is coated with a biphasic mixture of silver, indium, and gallium. This Ag–In–Ga coating functions as a soft electrode that is ultrathin, highly compliant, highly conductive, stretchable, and non‐smearing. Compared to carbon grease, sputter‐deposited metal coating, and particle‐filled conductive elastomers, this biphasic coating exhibits a unique combination of solid‐state integrity, extreme mechanical compliance, and low electrical resistivity. Herein, how DEAs with an Ag–In–Ga coating exhibit a 5× larger actuation speed compared to carbon‐coated dielectric films is shown. The influence of coating thickness on the mechanical stiffness and blocking force is also examined.
Real-Time Dual-Microphone Speech Enhancement Using Field Programmable Gate Arrays (2006)

The paper discusses an implementation of a dual-microphone phase-based speech enhancement technique. By using the phases of the incoming sound signals, we mask frequencies with low signal-to-noise ratio (SNR) between the two microphones. Phase-based filtering can achieve high SNR gains with just two microphones, making it ideal for hand-held devices. However, these devices have a limited battery life and lack the processing power needed for a software based implementation. The paper presents a field programmable gate array (FPGA) implementation that was designed specifically for low-power operation. The FPGA based implementation is compared, with respect to processing capabilities and power utilization, with an off-the-shelf low-power digital signal processor (DSP) implementation.

Bayesian Sparse Unsupervised Learning for Probit Models of Binary Data (2014)

We present a unified approach to unsuper-vised Bayesian learning of factor models for binary data with binary and spike-and-slab latent factors. We introduce a non-negative constraint in the spike-and-slab prior that eliminates the usual sign ambiguity present in factor models and lowers the generaliza-tion error on the datasets tested here. For the generative models we use probit functions, which can be sampled without tuning param-eters, unlike previous works that used logistic functions. The posterior distributions involve mixtures of binary and truncated Gaussian variables, for which we present exact Hamil-tonian Monte Carlo samplers and compare their properties to Gibbs samplers. 1
SON Coordination in Heterogeneous Networks: A Reinforcement Learning Framework (2016)

An important problem of today's mobile network operators is to bring down the capital expenditures and operational expenditures. One strategy is to automate the parameter tuning on the small cells through the so-called self-organizing network (SON) functionalities, such as cell range expansion, mobility robustness optimization, or enhanced Inter-Cell Interference Coordination. Having several of these functionalities in the network will surely create conflicts, as, for example, they may try to change the same parameter in the opposite directions. This raises that the need for an SON COordinator (SONCO) meant to arbitrate the parameter change requests of the SON functions, ensuring some degree of fairness. It is difficult to anticipate the impact of accepting several simultaneous requests. In this paper, we provide a SONCO design based on reinforcement learning (RL) as it allows us to learn from previous experiences and improve our future decisions. Typically, RL algorithms are complex. To reduce this complexity, we employ two flavors of function approximation and provide a study-case. Results show that the proposed SONCO design is capable of biasing this fairness among the SON functions by means of weights attributed to the SON functions. Also, we evaluate the tracking capability of the algorithms.
<title>Single closed contact for 0.18-micron photolithography process</title> (2000)

With the rapid advances of deep submicron semiconductor technology, identifying defects is converted into a challenge for different modules in the fabrication of chips. Yield engineers often do bitmap on a memory circuit array (SRAM) to identify the failure bits. This is followed by a wafer stripback to look for visual defects at each deprocessed layer for feedback to the Fab. However, to identify the root cause of a problem, Fab engineers must be able to detect similar defects either on the product wafers in process or some short loop test wafers. In the photolithography process, we recognize that the detection of defects is becoming as important as satisfying the critical dimension (CD) of the device. For a multi-level metallization chemically mechanical polish backend process, it is very difficult to detect missing contacts or via at the masking steps due to metal grain roughness, film color variation and/or previous layer defects. Often, photolithography engineer must depend on Photo Cell Monitor (PCM) and short loop experiments for controlling baseline defects and improvement. In this paper, we discuss the findings on the Poly mask PCM and the Contact mask PCM. We present the comparison between the Poly mask and the Contact mask of the I-line Phase Shifted Via mask and DUV mask process for a 0.18 micron process technology. The correlation and the different type of defects between the Contact PCM and the Poly Mask are discussed. The Contact PCM was found to be more sensitive and correlated to contact failure at sort yield better. We also dedicate to study the root cause of a single closed contact hole in the Contact mask short loop experiment for a 0.18 micron process technology. A single closed contact defect was often caused by the developer process, such as bubbles in the line, resist residue left behind, and the rinse mechanism. We also found surfactant solution helps to improve the surface tension of the wafer for the developer process and this prevents/eliminates a single closed contact hole defects. The applications and effects of using different substrates like SiON, different thicknesses of Oxides, and Poly in the Contact Photo Mask is shown. Finally, some defect troubleshooting techniques and the root cause analysis are also discussed.
Modulation of Ocular Surface Glycocalyx Barrier Function by a Galectin-3 N-terminal Deletion Mutant and Membrane-Anchored Synthetic Glycopolymers (2013)

These results indicate that galectin-3 multimerization and surface recognition of lactosyl residues is required to maintain glycocalyx barrier function at the ocular surface. Transient modification of galectin-3 binding could be therapeutically used to enhance the efficiency of topical drug delivery.
Optical enhancements on gold thin films through surface nanostructure modulation (2003)

Surface plasmons (SPs) on gold thin film coupling with the grating on the surface were studied. For films with periodic nanostructures, experimental results and simulations showed that the incident light was reflected as well as excited. Because the propagating wave is particular about the surface plasmons excitation, we used the FDTD simulations to predict the grating conditions such as the thickness, period, width, and depth. Optical transmission intensity enhancements due to the nanostructures on the gold thin films were observed in our results.
Chemical assembly of N-glycoproteins: a refined toolbox to address a ubiquitous posttranslational modification (2013)

Incremental developments in the chemistry of peptides, proteins and carbohydrates have enabled researchers to assemble entire glycoproteins with high precision. Based on sophisticated ligation chemistries pure glycoproteins bearing a single glycosylation pattern have become available. The impact of N-glycosylation on the function of glycoproteins is generally recognized but not well understood. Based on the recent advances in the synthesis of glycoproteins by chemical methods researchers can finally start to elucidate the various roles of carbohydrates in complex biomolecules in detail.
Co-Scheduling Variable Execution Time Requirement Real-Time Tasks and Non Real-Time Tasks (2007)

By scheduling the non real-time tasks earlier while still meeting deadlines for the real-time tasks, the overall system performance can be improved. In particular, we believe that the variability in the execution time requirements of real-time tasks can be effectively leveraged to reduce response times of non real-time tasks. We propose a novel processor sharing algorithm where the processor share of RT jobs increases with their progress based on the empirical probability distribution of execution times of real-time tasks, to adaptively schedule variable requirement real-time to maximize the minimum expected service rate to non real-time tasks at any instant.
"How May I Help You?" (2017)

Given the increasing popularity of customer service dialogue on Twitter, analysis of conversation data is essential to understand trends in customer and agent behavior for the purpose of automating customer service interactions. In this work, we develop a novel taxonomy of fine-grained "dialogue acts" frequently observed in customer service, showcasing acts that are more suited to the domain than the more generic existing taxonomies. Using a sequential SVM-HMM model, we model conversation flow, predicting the dialogue act of a given turn in real-time. We characterize differences between customer and agent behavior in Twitter customer service conversations, and investigate the effect of testing our system on different customer service industries. Finally, we use a data-driven approach to predict important conversation outcomes: customer satisfaction, customer frustration, and overall problem resolution. We show that the type and location of certain dialogue acts in a conversation have a significant effect on the probability of desirable and undesirable outcomes, and present actionable rules based on our findings. The patterns and rules we derive can be used as guidelines for outcome-driven automated customer service platforms.
13C−13C Rotational Resonance Width Distance Measurements in Uniformly13C-Labeled Peptides (2003)

The rotational resonance width (R2W) experiment is a constant-time version of the rotational resonance (R2) experiment, in which the magnetization exchange is measured as a function of sample spinning frequency rather than the mixing time. The significant advantage of this experiment over conventional R2 is that both the dipolar coupling and the relaxation parameters can be independently and unambiguously extracted from the magnetization exchange profile. In this paper, we combine R2W with two-dimensional 13C-13C chemical shift correlation spectroscopy and demonstrate the utility of this technique for the site-specific measurement of multiple 13C-13C distances in uniformly labeled solids. The dipolar truncation effects, usually associated with distance measurements in uniformly labeled solids, are considerably attenuated in R2W experiments. Thus, R2W experiments are applicable to uniformly labeled biological systems. To validate this statement, multiple 13C-13C distances (in the range of 3-6 A) were determined in N-acetyl-[U-13C,15N]l-Val-l-Leu with an average precision of +/-0.5 A. Furthermore, the distance constraints extracted using a two-spin model agree well with the X-ray crystallographic data.

The Influence of Processing Parameters on the Transition Zone for Blended Material 3D Printing (2020)

The use of Multiple Materials (MM) in Additive Manufacturing (AM) is increasingly important for expanding the range of applications in the manufacturing industry, particularly for large-format processes. Typically, polymer-based AM incorporates MM transitions through discrete interfaces between layers. This arrangement significantly increases the occurrence of layer delamination failures due to decreased bonding between dissimilar polymers. Elimination of discrete material interfaces by continuously transitioning from Material A to B provides a possible solution. Such continuous gradients could be used to create functionally graded structures that take full advantage of AM’s capability to deliberately impart site-specific properties. Cincinnati’s Big Area Additive Manufacturing (BAAM) system at Oak Ridge National Lab has been equipped with a dual-hopper system that enables in-situ material switching specifically intended for functionally graded and MM printing. The resulting material transition exhibits varied behavior based on printing conditions, which can have an impact on part design and resulting mechanical properties. In this work, the transition zone is characterized as a function of the printing screw speed (related to volumetric flow) and the screw geometry.
Nonlinear optical phenomena on rough surfaces of metal thin films (1998)

Nonlinear optical phenomena on rough self-affine metal surfaces are theoretically studied. Placing nonlinearly polarizable molecules on such surfaces results in strong enhancement of optical nonlinearities. A quasistatic approximation is used to calculate local-enhancement factors for the second and third harmonic generation, degenerate four-wave mixing, and nonlinear Kerr effect. The calculations show that the average enhancement factors on a self-affine surface can be as large as ${10}^{7}$ and ${10}^{15}$ for optical nonlinearities of the second and third order, respectively, with the maximum average enhancement in the infrared spectral range. Strong spatial inhomogeneity of local-enhancement distribution is demonstrated for the second and third harmonic generation. The local enhancement can exceed the average by several orders of magnitude, reaching extremely high values. Sharp peaks in local-field intensities at fundamental and generated frequencies are localized in spatially separated nanometer-sized areas of the film.
