DistanciAR: Authoring Site-Specific Augmented Reality Experiences for Remote Environments (2021)

Most augmented reality (AR) authoring tools only support the author’s current environment, but designers often need to create site-specific experiences for a different environment. We propose DistanciAR, a novel tablet-based workflow for remote AR authoring. Our baseline solution involves three steps. A remote environment is captured by a camera with LiDAR; then, the author creates an AR experience from a different location using AR interactions; finally, a remote viewer consumes the AR content on site. A formative study revealed understanding and navigating the remote space as key challenges with this solution. We improved the authoring interface by adding two novel modes: Dollhouse, which renders a bird’s-eye view, and Peek, which creates photorealistic composite images using captured images. A second study compared this improved system with the baseline, and participants reported that the new modes made it easier to understand and navigate the remote scene.
Negative chronotropic factor in patients with fungemia (1992)

Serum from many patients with fungemia causes slowing of an in vitro sinus node preparation. This in vitro finding may explain bradyarrhythmias seen clinically in the setting of fungemia.
Stimulation of cyclic adenosine monophosphate accumulation causes breakdown of the blood-retinal barrier. (1991)

Pigmented rabbits were given an intravitreous injection of 0.1 ml of various concentrations of test drug, and vitreous fluorophotometry was done 6 and 24 hr after injection. Dibutyryl cyclic adenosine monophosphate (AMP) and 8-bromo-cyclic AMP caused reversible intravitreous fluorescein leakage only at relatively high concentrations. Adrenergic agents that are effective stimulators of adenylate cyclase (epinephrine, isoproterenol, and norepinephrine) caused transient intravitreous fluorescein leakage (2.3-3.1-fold above baseline) that was significantly greater than that caused by phenylephrine (1.1-fold above baseline), an adrenergic agent that is a poor stimulator of adenylate cyclase. Prostaglandins E1 and E2, which are good stimulators of adenylate cyclase, caused striking disruption of the blood-ocular barriers, and prostaglandins that are not good stimulators of adenylate cyclase had little or no effect on these barriers. The magnitude of the prostaglandin E1 effect (9.3-fold above baseline) was similar to that of N-ethylcarboxamidoadenosine (NECA), the most potent adenosine agonist, and was greater than one would predict based on its effect on adenylate cyclase in vitro. Prostaglandin E1, like NECA, also caused retinal vasodilation and hemorrhages. These data suggest that stimulation of intracellular cyclic AMP accumulation may be a common feature of mediators that cause breakdown of the blood-retinal barrier, but there may be another as yet unexplained feature shared by PGE1 and NECA that makes them particularly effective and capable of causing retinal vasodilation and hemorrhages.
ChemInform Abstract: AN APPROACH TO THE CONSTRUCTION OF THE AROMATIC PORTIONS OF NAPHTHOMYCIN AND THE RUBRADIRINS. NUCLEOPHILIC ADDITIONS TO UNSYMMETRICALLY SUBSTITUTED NAPHTHOQUINONES (1980)

Abstract 2‐Hydroxy‐acetanilid (I) liefert durch Behandeln mit Fremyschem Salz und Iod das Acetamido‐iod‐chinon (II), das mit dem Butadien (III) zu einem Addukt (IV) führt und in Gegenwart von HCl mit Luft zum Naphthochinon (V) oxidiert wird.
Improvement of a respiratory ozone analyzer. (1997)

The breath-to-breath measurement of total respiratory ozone (O3) uptake requires monitoring O3 concentration at the airway opening with an instrument that responds rapidly relative to the breathing frequency. Our original chemiluminescent analyzer, using 2-methyl-2-butene as the reactant gas, had a 10% to 90% step-response time of 110 msec and a minimal detectable concentration of 0.018 parts per million (ppm) O3 (Ben-Jebria et al. 1990). This instrument was suitable for respiratory O3 monitoring during quiet breathing and light exercise. For this study, we constructed a more self-contained analyzer with a faster response time using ethylene as the reactant gas. When the analyzer was operated at a reaction chamber pressure of 350 torr, an ethylene-to-sample flow ratio of 4:1, and a sampling flow of 0.6 liters per minute (Lpm), it had a 10% to 90% step-response time of 70 msec and a minimal detectable concentration of 0.006 ppm. These specifications make respiratory O3 monitoring possible during moderate-to-heavy exercise. In addition, the nonlinear calibration and the carbon dioxide (CO2) interference exhibited by the original analyzer were eliminated. In breath-to-breath measurements in two healthy men, the fractional uptake of O3 during one minute of quiet breathing was comparable to the results obtained by using a slowly responding commercial analyzer with a quasi-steady material balance method (Wiester et al. 1996). In fact, fractional uptake was about 0.8 regardless of O3 exposure concentration (0.11 to 0.43 ppm) or ventilation rate (4 to 41 Lpm/m2).
Novel antibiotics, amythiamicins. II. Structure elucidation of amythiamicin D. (1994)

The structure of a unique polythiazole-containing cyclic peptide antibiotic, amythiamicin D, was elucidated by chemical degradations and NMR spectral analyses. Acid hydrolysis of amythiamicin D gave one mole of glycine and three new amino acids. Structures of N-acetyl-O-methyl derivatives of these new amino acids were determined by NMR and UV spectral analyses. Connectivities of these amino acids were determined by HMBC experiments.
Reducing dielectric loss and enhancing electrical insulation for multilayer polymer films by nanoconfined ion transport under high poling electric fields (2020)

High-field electric poling locks impurity ions at interfaces in multilayer polymer films, which enhances dielectric insulation and reduces ionic conduction loss for electric energy storage applications.
Adapting Deep Learning Models to New Meteorological Contexts Using Transfer Learning (2021)

Meteorological applications such as precipitation nowcasting, synthetic radar generation, statistical downscaling and others have benefited from deep learning (DL) approaches, however several challenges remain for widespread adaptation of these complex models in operational systems. One of these challenges is adequate generalizability; deep learning models trained from datasets collected in specific contexts should not be expected to perform as well when applied to different contexts required by large operational systems. One obvious mitigation for this is to collect massive amounts of training data that cover all expected meteorological contexts, however this is not only costly and difficult to manage, but is also not possible in many parts of the globe where certain sensing platforms are sparse. In this paper, we describe an application of transfer learning to perform domain transfer for deep learning models. We demonstrate a transfer learning algorithm called weight superposition to adapt a Convolutional Neural Network trained in a source context to a new target context. Weight superposition is a method for storing multiple models within a single set of parameters thus greatly simplifying model maintenance and training. This approach also addresses the issue of catastrophic forgetting where a model, once adapted to a new context, performs poorly in the original context. We apply weight superposition to the problem of synthetic weather radar generation and show that in scenarios where the target context has less data, a model adapted with weight superposition is better at maintaining performance when compared to simpler methods. Conversely, the simple adapted model performs better on the source context when the source and target contexts have comparable amounts of data.
An Additive Model as a Physical Basis for Shadow Fading (2007)

Received signal power in mobile wireless communications is typically modeled as a product of three factors: distance-dependent average path loss law, variation in the local mean power (shadow fading), and small-scale fading. Of these three factors, the least investigated is the shadow fading, which is usually explained as a result of multiplication of large number of random attenuating factors in the radio channel. In this paper, the authors propose an additive model as an alternative physical basis for shadow fading within an "extended local area" where path loss is constant. Starting from a sum-of-sinusoids signal model, they show that under mild statistical assumptions on the powers of the sinusoids, the resulting signal power will have approximately Gaussian distribution in logarithmic scale. A cluster-based model for shadow fading emerges as a special instance of the general result. They present simulation and measurement results that support their theoretical findings. The new physical basis for shadow fading also provides insights into simulation and modeling of radio channels
In vivo magnetic resonance measures of dark cytotoxicity of photosensitizers in a Murine tumor model (2005)

Photodynamic therapy (PDT) is a novel cancer treatment modality where the therapeutic action is controlled by light and the potency of the photosensitizer used. Development of new potent photosensitizers (PS) for clinical applications requires that the PDT effects are maximized while minimizing dark cytotoxicity. The dark toxicity of photosensitizers is generally confirmed using cell lines. Photososensitizers that appear promising from in vitro assays need further investigations under in vivo conditions. As in vivo MR methods have the potential to provide information on the tumor status, they can be very effective tools to study dark toxicity of tumors. The tumor produced on the mouse foot dorsum was tested on two newly synthesized photosensitizers along with Photofrin as a control. The MR studies consisted of serial <sup>31</sup>P spectral measurements both before and after PS injection. The results show significant changes in the tumor metabolism with increased inorganic phosphate while using new photosensitizers. However these changes slowly approached control levels several hours later. The studies performed while using Photofrin did not show any significant changes indicating minimal or no dark cytotoxicity. Similar studies performed on normal tissue such as the muscle indicated that the energy metabolism was minimally compromised. Our studies demonstrate that the effects of dark cytotoxicity can be observed by <sup>31</sup>P MR. The growth profiles of tumors treated with PS alone indicate that the metabolic changes are temporary and do not interfere with the tumor growth. The studies suggest that MR is a new method of monitoring the effect of PS administered toxicity in an in vivo model.
Single-transducer acoustic levitator with equidistant vertical positioning capability (2016)

We present an acoustic levitator experiment in air, in which objects can be vertically positioned to several equidistant locations. The setup consists of only one single-element transducer and one reflector. The main objective of this work was to investigate whether it is possible to move and position an object vertically in such a setup with only one narrowband single-element transducer and only one reflector, without moving the transducer or reflector at all. The key idea is that we exploit gravity to let the object fall from one pressure nodal node to one at a lower position. This is achieved by amplitude modulation of the transducers driving signal with varying gap times in order to match the free-fall time of the levitated object from one nodal plane to one of the nodal planes below. The levitator is able to generate sound pressure levels of up to 163 dB SPL, and, thus, capable of levitating lightweight objects over longer distances of several centimeters and high density samples such as water drops, glass or steel spheres over shorter distances. Our results prove that the levitated objects can be precisely and reproducibly transported from a higher pressure nodal plane to the next lower nodal plane position.
Response: novel lysosomal-dependent cell death following homotypic adhesion occurs within cell aggregates (2010)

serum showed more than 70% cell death in cytospins (Figure Large aggregates containing 30 to 100 cells are probably mostly excluded from the analysis, falling outside the gate of scatter plots. Dead cells are in contrast enriched within the single-cell population because aggregation is an energy-dependent process. An apparent rapid loss of cells due to aggregation was confirmed in flow cytometry by counting the absolute number of events using calibrated beads. Indeed, 87% and 70% apparent decrease in total cell number was observed at 24 hours in anti-HLA-DR-and B1-treated samples, respectively (Figure
Model based control for a fine coal injection plant (1999)

Modeling, control, and gas leakage detection in the coal injection process are discussed. It is shown that by use of model-based methods, the flow and pressure of the coal injection vessel are reliably controlled. With the new control law, the coal mass flow can be used as a control parameter for the blast furnace. High injection rates can be used and more coke substituted, This is expected to yield a cost reduction in the iron production. An experimental comparison of the conventional control unit with the one suggested in this article shows that an improvement of the process efficiency can be reached by other means than increasing the capacity of the plant.
Gear up your bearings (2008)

This article identified three electrical mechanisms that cause bearing damage. The three sources of bearing currents are electromagnetic induction (circulating current), electrostatic EDM coupled sources (mechanical or electrical coupled), and ground sources (backfeeding). This also presented field test measurements related to bearing damage. A field methodology was presented to identify electrical bearing conditions in motors that are still running. Mitigation actions are described and applied to two motor ASD application sites. Test measurements were taken to determine the effectiveness of the mitigation action. In most cases, two or all of the bearing current mechanisms can be identified by reviewing the installation and application of the motor with voltage and current measurements with time and frequency analysis. A combination of mitigation strategies is normally used on the basis of the bearing current coupling mechanisms.
Recent Developments for EPDM‐Based Thermoplastic Vulcanisates (2006)

Abstract An overview will be given on thermoplastic vulcanisates (TPVs). Like other thermoplastic elastomers, TPVs combine the elastic and mechanical properties of thermoset cross‐linked rubbers with the melt processability of thermoplastics. Emphasis will be on general‐purpose TPVs, based on resol‐cross‐linked EPDM/PP/oil blends. The following recent scientific developments will be discussed in detail: resol cross‐linking chemistry, extruder dynamic vulcanisation, TPV morphology, oil distribution, TPV elasticity model and TPV rheology. A series of scientific questions and technological problems, which are challenging future TPV developments, will be put forward at the end.
A John White Alexander painting: A comparison of imaging technologies for resolving a painting under another painting (2019)

Reflectance imaging spectroscopy (RIS) in the visible and near infrared is revolutionizing the way cultural heritage investigators may analyze paintings nondestructively. In an ongoing, highly collaborative project, the authors are investigating a painting by American artist John White Alexander (1856–1915). The painting, titled A Study in Pink, is in the collection of the Virginia Museum of Fine Arts (VMFA). An x-radiograph taken in 2014 revealed that there was a painting of another female figure, rotated 180 degrees, underneath the current composition. With this discovery, A Study in Pink became an ideal case study for evaluating the advantages and limitations of nondestructive instrumentation for the purpose of providing useful art historical information on cultural heritage objects. The study examined the information obtained using low cost (US$15,000) as well as high cost (US$300,000) imaging instrumentation. Additionally, the authors are seeking ways of making these technologies robust for in-field non-experts, as well as practical research instruments for undergraduate and graduate education. The preliminary research results revealed that the face of the female figure underneath A Study in Pink could be partially retrieved using RIS multi-spectral imaging equipment operating from 900-1700 nm and more completely revealed using RIS equipment operating from 400-2350 nm.
A simple reconstruction of GPSG (1986)

Like most linguistic theories, the theory of generalized phrase structure grammar (GPSG) has described language axiomatically, that is, as a set of universal and language-specific constraints on the well-formedness of linguistic elements of some sort. The coverage and detailed analysis of English grammar in the ambitious recent volume by Gazdar, Klein, Pullum, and Sag entitled Generalized Phrase Structure Grammar [2] are impressive, in part because of the complexity of the axiomatic system developed by the authors. In this paper. We examine the possibility that simpler descriptions of the same theory can be achieved through a slightly different, albeit still axiomatic, method, Rither than characterize the well-formed trees directly, we progress in two stages by procedurally characterizing the well-formedness axioms themselves, which in turn characterize the trees.

Simultaneous German-English lecture translation (2008)

In an increasingly globalized world, situations in which people of different native tongues have to communicate with each other become more and more frequent. In many such situations, human interpreters are prohibitively expensive or simply not available. Automatic spoken language translation (SLT), as a cost-effective solution to this dilemma, has received increased attention in recent years. For a broad number of applications, including live SLT of lectures and oral presentations, these automatic systems should ideally operate in real time and with low latency. Large and highly specialized vocabularies as well as strong variations in speaking style – ranging from read speech to free presentations suffering from spontaneous events – make simultaneous SLT of lectures a challenging task. This paper presents our progress in building a simultaneous German-English lecture translation system. We emphasize some of the challenges which are particular to this language pair and propose solutions to tackle some of the problems encountered.

(Invited) Developing Optical Nanosensors for the Early Detection of Gynecologic Cancers (2022)

Uterine and ovarian cancer patients' prognosis and quality of life are significantly affected by the failure to diagnose the disease accurately. Early detection may save more than 80% of women diagnosed with ovarian cancer. Therefore, developing new platforms for better detecting potential biomarkers in both biofluid samples and in-situ may significantly improve early detection and better survival. Here we propose two platforms to detect multiple cancer biomarkers in cancer patients' specimens and detect specific biomarkers in-situ using implantable sensors. These technologies harness the unique optical properties of single-walled carbon nanotubes (SWCNTs)-based sensors and artificial intelligent algorithms. We developed an array of DNA-SWCNT sensors that composed a library of ssDNA sequences and multiple chiralities of SWCNTs to detect various biomarkers within patient clinical samples. Harnessing machine learning algorithms to process the optical response of the sensors enabled the precise detection of the unique spectroscopic fingerprints of each of the biomarkers in uterine washing clinical samples. For detecting biomarkers within the uteri of the patients, we developed an implantable sensor that serves as an implantable intrauterine device. The sensor can detect cancer biomarkers and differentiate between benign and malignant cases.
Growth hormone gene expression in myoepithelial cells directed by various eucaryotic transcriptional regulatory sequences (1987)

Mammary gland myoepithelial cells were isolated from cattle and cell lines were established. Cells were plated onto tissue culture dishes with or without collagen. Cells were transfected with bovine growth hormone rDNA containing one of the following eucaryotic transcriptional regulatory sequences: human cytomegalovirus immediate early promoter, simian virus 40 early promoter, mouse metallothionein I promoter and the Rous sarcoma virus long terminal repeat. These sequences were evaluated for their ability to direct recombinant bovine growth hormone DNA expression in myoepithelial cells. The most effective transcriptional regulatory sequences were the cytomegalovirus immediate early and simian virus 40 early promoters.
