IFS fractal interpolation for 2D and 3D visualization (1995)

Reconstruction is used frequently in visualization of one, two, and three--dimensional data. Data uncertainty is typically ignored, and a deficiency of many interpolation schemes is smoothing which may indicate features or characteristics of the data that are not there. In this paper I investigate the use of iterated function systems (IFS's) for interpolation. I show new derivations for fractal interpolation in two and three-dimensional scalar data, and new point and polytope rendering algorithms with tremendous speed advantages over ray tracing. The interpolations may be used to give an indication of the uncertainty of the data, statistically represent the data at a variety of scales, allow tunability from the data, and may allow more accurate data analysis.
Excessive Islet NO Generation in Type 2 Diabetic GK Rats Coincides with Abnormal Hormone Secretion and Is Counteracted by GLP-1 (2008)

The results suggest that abnormally increased NO production within islet cells is a significant player in the pathogenesis of type 2 diabetes being counteracted by GLP-1 through PKA-dependent, nonproteasomal mechanisms.
A Birthday Celebration for John S. Fordtran, MD (2012)

On November 15, 2011, a celebration was held for John S. Fordtran, MD (Figure ​(Figure11), on the occasion of his 80th birthday. The event was initially suggested by Dr. Fordtran's long-time colleague, Guenter Krejs, MD, who traveled to Dallas from Austria for the event. He was assisted by Charles Richardson, MD, and C. Richard Boland, MD.
A multiphase PWM RF modulator using a VCO-based opamp in 45nm CMOS (2010)

A VCO-based RF modulator employing multiphase Pulse Width Modulation (PWM) is presented. The proposed RF modulator encodes the baseband signal into a set of multiphase PWM signals which are generated by a VCO-based opamp. The use of PWM avoids broadband quantization noise which is produced by ΣΔ modulation used in other RFDAC-based modulators. The prototype IC is fabricated in a 45nm CMOS process, consumes 54.3 mW, and has an active area of 0.126 mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> . The measured results satisfy the 802.11g WLAN spectral mask, and EVM for 10-MHz, 64 QAM OFDM at 2.4 GHz is -30 dB.
Detection of Viruses from Bioaerosols Using Anion Exchange Resin (2018)

This protocol demonstrates a customized bioaerosol sampling method for viruses. In this system, anion exchange resin is coupled with liquid impingement-based air sampling devices for efficacious concentration of negatively-charged viruses from bioaerosols. Thus, the resin serves as an additional concentration step in the bioaerosol sampling workflow. Nucleic acid extraction of the viral particles is then performed directly from the anion exchange resin, with the resulting sample suitable for molecular analyses. Further, this protocol describes a custom-built bioaerosol chamber capable of generating virus-laden bioaerosols under a variety of environmental conditions and allowing for continuous monitoring of environmental variables such as temperature, humidity, wind speed, and aerosol mass concentration. The main advantage of using this protocol is increased sensitivity of viral detection, as assessed via direct comparison to an unmodified conventional liquid impinger. Other advantages include the potential to concentrate diverse negatively-charged viruses, the low cost of anion exchange resin (~$0.14 per sample), and ease of use. Disadvantages include the inability of this protocol to assess infectivity of resin-adsorbed viral particles, and potentially the need for the optimization of the liquid sampling buffer used within the impinger.
Elevated VEGF-D Modulates Tumor Inflammation and Reduces the Growth of Carcinogen-Induced Skin Tumors (2016)

Vascular endothelial growth factor D (VEGF-D) promotes the lymph node metastasis of cancer by inducing the growth of lymphatic vasculature, but its specific roles in tumorigenesis have not been elucidated. We monitored the effects of VEGF-D in cutaneous squamous cell carcinoma (cSCC) by subjecting transgenic mice overexpressing VEGF-D in the skin (K14-mVEGF-D) and VEGF-D knockout mice to a chemical skin carcinogenesis protocol involving 7,12-dimethylbenz[a]anthracene and 12-O-tetradecanoylphorbol-13-acetate treatments. In K14-mVEGF-D mice, tumor lymphangiogenesis was significantly increased and the frequency of lymph node metastasis was elevated in comparison with controls. Most notably, the papillomas regressed more often in K14-mVEGF-D mice than in littermate controls, resulting in a delay in tumor incidence and a remarkable reduction in the total tumor number. Skin tumor growth and metastasis were not obviously affected in the absence of VEGF-D; however, the knockout mice showed a trend for reduced lymphangiogenesis in skin tumors and in the untreated skin. Interestingly, K14-mVEGF-D mice showed an altered immune response in skin tumors. This consisted of the reduced accumulation of macrophages, mast cells, and CD4(+) T-cells and an increase of cytotoxic CD8(+) T-cells. Cytokine profiling by flow cytometry and quantitative real time PCR revealed that elevated VEGF-D expression results in an attenuated Th2 response and promotes M1/Th1 and Th17 polarization in the early stage of skin carcinogenesis, leading to an anti-tumoral immune environment and the regression of primary tumors. Our data suggest that VEGF-D may be beneficial in early-stage tumors since it suppresses the pro-tumorigenic inflammation, while at later stages VEGF-D-induced tumor lymphatics provide a route for metastasis.
Observation of nonlinear transmission prior to laser damage in ZrO2 (1986)

We report direct measurements of nonlinear transmission prior to laser-induced breakdown in a wide band gap dielectric. Various workers have suggested that bulk laser-induced breakdown is due to avalanche breakdown induced by multiphoton absorption. A detailed quantitative description of the generation of the initial conduction band electrons and the dynamics of the breakdown process is not yet available. A major obstacle to the development of a quantitative description of the damage process has been the inability of researchers to measure the onset of nonlinear absorption (e.g., multiphoton absorption) which initiates the avalanche process. In this work we observe pronounced, reversible nonlinear transmission prior to bulk breakdown. The sample studied was cubic zirconia (ZrO 2 ) stabilized with yttria (Y 2 O 3 ) which has an UV transmission cutoff at 330 nm. Our measurements were made at 532 nm which is within the range where two-photon absorption is possible. The observed nonlinear transmission prior to breakdown is consistent with the interpretation that damage in this material is due to two-photon absorption-induced avalanche breakdown.
A dual transcriptional activation system for the 230 kb plasmid genes coding for virulence‐associated antigens of Shigella flexneri (1989)

The expression of plasmid-encoded, invasion-related antigens lpa b, c and d of Shigella flexneri was found to be positively regulated at transcriptional level by a 33kD protein produced by the previously defined, virulence-associated Region 1 on the SalI fragment B of the 230 kb invasion plasmid. The gene (designated virB) was identified and its nucleotide sequence determined. No Ipa b or c was produced in the absence of an intact virB gene although lower levels of d were produced. The previously reported regulatory activity of the virF gene some 30 kb distance away was shown to act exclusively through virB. In contrast, the activation of the virG gene necessary for intercellular spread occurred directly by virF without the requirement for virB. This study thus ascribes a critical function to a previously recognized, but functionally undefined, virulence locus on the large invasion plasmid of S. flexneri. The virF gene appears to have a central role in activation of the 230 kb plasmid-encoded virulence genes.
High-Fidelity and High-Capacity Analog Radio-over-Fiber Transmission (2022)

In this invited paper, we review our recent progress on analog radio-over-fiber (RoF) technology for mobile fronthaul systems from two perspectives. The results show the feasibility of high-capacity and high-fidelity analog mobile fronthaul.
Consequences Arising From Elevated Surface Temperatures on Human Blood (2010)

Heat in blood pumps is generated by losses of the electrical motor and bearings. In the presented study the influence of tempered surfaces on bulk blood and adhesions on these surfaces was examined. Titanium alloy housing dummies were immersed in 25 mL heparinized human blood. The dummies were constantly tempered at specific temperatures (37-45 °C) over 15 min. Blood samples were withdrawn for blood parameter analysis and the determination of the plasmatic coagulation cascade. The quantities of adhesion on surfaces were determined by drained weight. Blood parameters do not alter significantly up to surface temperatures of 45 °C. In comparison to the control specimen, a drop in the platelet count can be observed, but is not significantly temperature dependent. The mean mass of adhesions at 41 °C increased up to 66% compared to 37 °C. Thus, heat generated in electrical motors and contact bearings may influence the amount of adhesions on surfaces.
Dynamics of nonlinear scattering in carbon black suspensions (1991)

Passive optical limiting can be illustrated in a variety of architectures where one can efficiently exploit self-induced nonlinearities in different materials. Some of the well-known self-induced effects that provide passive optical limiting are self-focusing,1 self-defocusing,2 and two-photon absorption.2 Here, we analyze the fluence dependent nonlinear scattering process in carbon black suspensions in liquids (CBS), which we previously showed is the dominant mechanism leading to optical limiting in CBS.4
A New Phase of the Na+ Ion Conductor Na3PS4 (2019)

&lt;div&gt; &lt;p&gt;Solid electrolytes are crucial for next‑generation solid‑state batteries and Na&lt;sub&gt;3&lt;/sub&gt;PS&lt;sub&gt;4&lt;/sub&gt; is one of the most promising Na&lt;sup&gt;+&lt;/sup&gt; conductors for such applications. At present, two phases of Na&lt;sub&gt;3&lt;/sub&gt;PS&lt;sub&gt;4&lt;/sub&gt; have been identified and it had been thought to melt above 500 °C. In contrast, we show that it remains solid above this temperature and transforms into a third polymorph, γ, exhibiting superionic behavior. We propose an orthorhombic crystal structure for γ‑Na&lt;sub&gt;3&lt;/sub&gt;PS&lt;sub&gt;4&lt;/sub&gt; based on scattering density analysis of diffraction data and density functional theory calculations. We show that the Na&lt;sup&gt;+&lt;/sup&gt; superionic behavior is associated with rotational motion of the thiophosphate polyanions pointing to a rotor phase, based on &lt;i&gt;ab initio&lt;/i&gt; molecular dynamics simulations and supported by high‑temperature synchrotron and neutron diffraction, thermal analysis and impedance spectroscopy. These findings are of importance for the development of new polyanion‑based solid electrolytes.&lt;/p&gt; &lt;/div&gt;
Fabrication of thin-film micropolarizer arrays for visible imaging polarimetry (2000)

We describe a microfabrication process for fabricating micropolarizer devices with polarization thin film. The polarization film is less than a 0.5 microm thick and can have a polarization extinction ratio of approximately 330 in the visible wavelength range. A single-state micropolarizer array with polarizing pixels as small as 5 microm x 5 microm has been fabricated. A multilayer spatially multiplexed three-state micropolarizer line array with a 14.4-microm resolution has also been fabricated for visible imaging polarimetry application.
다중참여형 퍼포먼스를 위한 엔터테인먼트디자인 (2013)

In recent cultural performing arts, the usage of digital technology media has enabled various and effective artistic expressions. Among these media, interactive media is formed by a variety of communication methods, but it is especially based on audience participation. Thus, the audiences role is more significant as a collaborator than the traditional contemplative rol -e. However, there are no performances that optimize interactive media to maximize the audience participation. The reason is that in most of the interactive media performances, the media is more focused on visual and auditory effects. This research analyzes the involvement of the audience and different cases of performances to suggest a new multiparticipatory performance utilizing smart devices.
Community Detection with Side Information via Semidefinite Programming (2019)

Semidefinite programming is known to be both efficient and asymptotically optimal in solving community detection problems, but it has been studied in this context only when observations are purely graphical in nature. In this paper, we extend the use of semidefinite programming in community detection to observations that have both a graphical and a nongraphical component. We consider the binary censored block model with n nodes and study the effect of partially revealed labels on the performance of semidefinite programming. We address the question: do partially revealed labels help the semidefinite programming solution as much as they help the maximum likelihood solution? Our results are twofold. First, we show that partially revealed labels change the phase transition of exact recovery if and only if the information they provide grows no slower than Ω(log(n)). Second, we show that the semidefinite programming relaxation of maximum likelihood can achieve exact recovery down to the optimal threshold under partially revealed labels.
Application of a new approach to optical proximity correction (1999)

Optical proximity correction is one of the major hurdles chip manufacturing has to overcome. The paper presents evaluation results of CAPROX OPC, a rule based OPC software. Mask making influences as well as production requirements are discussed. Rule generation, one of the most critical parts in a rule based correction scheme is discussed. Two different applications are presented.
Activity of TGR-1202, a novel once-daily PI3Kδ inhibitor, in patients with relapsed or refractory hematologic malignancies. (2014)

2513 Background: TGR-1202 is a novel, next generation PI3Kδ inhibitor. Preliminary data from an ongoing Ph I study of TGR-1202 demonstrated clinical activity in patients (pts) with advanced hematologic malignancies. Herein we present updated results from this Phase I, first in human study of TGR-1202. Methods: TGR-1202 is administered orally daily following a 3+3 dose escalation design. Previously treated pts with an ECOG PS < 2 and confirmed diagnosis of B-cell non-Hodgkin lymphoma (NHL), chronic lymphocytic leukemia (CLL), or other lymphoproliferative disorders are eligible. Endpoints include safety, PK/PD, and efficacy. Results: 27 pts have been enrolled to date across 7 dose levels: 50, 100, 200, 400, 800, 1200, and 1800 mg QD. 74% male, ECOG 0/1: 33%/67%, median age of 59 yrs (range: 28-82), median 3 (range: 1-14) prior treatment regimens, and 40% were refractory to prior treatment. Evaluable pts include 7 indolent NHL (iNHL), 11 CLL/SLL, 4 Hodgkin’s lymphoma (HL), 2 mantle cell lymphoma (MCL), 1 each of lymphoplasmacytic lymphoma, DLBCL, and atypical hairy cell leukemia. TGR-1202 was well tolerated. Gr≥3 AE’s in >5% of patients were limited to: dyspnea (7%), neutropenia (15%), rash (7%), and thrombocytopenia (7%). Two DLTs were observed: 1 Gr. 3 rash at 800 mg (pt rechallenged with no recurrence), and 1 Gr. 3 hypokalemia at 1800 mg (pt discontinued due to non-compliance). Notably, no hepatotoxicity has been observed to date. Of the 27 enrolled, 23 were evaluable for efficacy. A significant dose-response relationship was observed. Of the 13 pts treated at < 800 mg QD who completed 2 cycles of treatment, 7 achieved SD. Of 10 pts treated at ≥ 800 mg QD: 4/6 CLL pts (67%) achieved a nodal PR, 1/3 Hodgkin’s pts (33%) achieved a PR. Nodal reductions occurred rapidly in patients with CLL and were accompanied by marked lymphocytosis. Conclusions: TGR-1202 is well tolerated in pts with rel/ref hematologic malignancies with no reported hepatic toxicity and signs of clinical activity at doses ≥ 800 mg QD. Enrollment continues in expansion cohorts and at higher dose cohorts. Updated safety, efficacy, PK, and PD data will be presented. Clinical trial information: NCT01767766.
Theory of seismic waves (1995)

The seismic method utilizes the propagation of waves through the earth. To introduce the basic concepts of wave motion, we first discuss waves on a stretched string (§2.1.1) and introduce definitions of phase, frequency, wavelength, and other terms dealing with periodicity. Because wave propagation depends upon the elastic properties of the rocks, we next discuss some of the basic concepts of elasticity. (For more thorough treatments, see Saada, 1974, or Landau and Lifshitz, 1986.)

Aging of γ′ Precipitates at 750 °C in the Nickel-Based Superalloy AD730TM: A Thermally or Thermo-Mechanically Controlled Process? (2020)

The microstructural stability during aging at 750 °C of the γ/γ′ nickel-based superalloy AD730TM is investigated in this work. Strain-free aging and aging during fatigue tests are conducted, with a focus on the influence of the strain ratio, the maximum applied strain, and the cycle waveform (with or without dwell). Two classical mechanisms of γ′ precipitates aging are identified at 750 °C: the coarsening of small spherical γ′ precipitates via the thermally-activated Ostwald ripening process and the coalescence of at least two precipitates into one. These mechanisms appeared to be concomitant during aging. It has been demonstrated that the coarsening kinetics of γ′ precipitates can be described by a classical Lifshitz-Slyozow-Wagner (LSW) equation. The introduction of a cyclic strain during aging at 750 °C increases the coarsening kinetics by means of changes in the volume diffusion of γ′-forming elements and of constraint misfit effects. More precisely, it is shown that the higher the maximum applied strain and/or the strain rate, the higher the coarsening rates. Finally, dwell-fatigue promotes the activation of the γ′ coalescence at 750 °C.
Evaluation of Antimicrobial and Lipopolysaccharide-Neutralizing Effects of a Synthetic CAP18 Fragment againstPseudomonas aeruginosain a Mouse Model (1998)

ABSTRACT CAP18 (cationic antimicrobial protein; 18 kDa) is a neutrophil-derived protein that can bind to and inhibit various activities of lipopolysaccharide (LPS). The 37 C-terminal amino acids of CAP18 make up the LPS-binding domain. A truncated 32-amino-acid C-terminal fragment of CAP18 had potent activity against Pseudomonas aeruginosa in vitro. We studied the antimicrobial and LPS-neutralizing effects of this synthetic truncated CAP18 peptide (CAP18 106–137 ) on lung injury in mice infected with cytotoxic P. aeruginosa . To determine its maximal effect, the CAP18 106–137 peptide was mixed with bacteria just prior to tracheal instillation, and lung injury was evaluated by determining the amount of leakage of an alveolar protein tracer ( 125 I-albumin) into the circulation and by the quantification of lung edema. The lung injury caused by the instillation of 5 × 10 5 CFU of P. aeruginosa was significantly reduced by the concomitant instillation of CAP18 106–137 . However, the administration of CAP18 106–137 alone, without bacteria, induced lung edema, suggesting that it has some toxicity. Also, the peptide did not significantly reduce the number of bacteria that had been simultaneously instilled, nor did it significantly improve the survival of the infected mice. The addition of CAP18 106–137 to aztreonam along with the bacteria did decrease the level of antibiotic-induced release of inflammatory mediators including tumor necrosis factor alpha, interleukin-6, and nitric oxide and also improved the survival of the mice. Therefore, more investigations are needed to confirm the toxicities and the therapeutic benefits of CAP18 106–137 as an adjunctive therapy to antibiotics in the treatment of infections caused by gram-negative bacteria.
Slow-plasmon resonant-nanostrip antennas: Analysis and demonstration (2008)

Resonant scattering by gold nanostrip antennas due to constructive interference of counterpropagating slow surface plasmon polaritons (SPPs) is analyzed, including the quasistatic limit of ultrasmall antennas, and experimentally demonstrated. The phase of slow SPP reflection by strip ends is found from scattering spectra revealing the influence of non-SPP field components. Experimental scattering spectra of gold 17- and $23\text{\ensuremath{-}}\mathrm{nm}$-thin strips of $100--500\phantom{\rule{0.3em}{0ex}}\mathrm{nm}$ widths placed on quartz and covered with index-matching oil are in excellent agreement with theoretical predictions.
Detecting Input Recognition Errors and User Errors using Gaze Dynamics in Virtual Reality (2022)

Gesture-based recognition systems are susceptible to input recognition errors and user errors, both of which negatively affect user experiences and can be frustrating to correct. Prior work has suggested that user gaze patterns following an input event could be used to detect input recognition errors and subsequently improve interaction. However, to be useful, error detection systems would need to detect various types of high-cost errors. Furthermore, to build a reliable detection model for errors, gaze behaviour following these errors must be manifested consistently across different tasks. Using data analysis and machine learning models, this research examined gaze dynamics following input events in virtual reality (VR). Across three distinct point-and-select tasks, we found differences in user gaze patterns following three input events: correctly recognized input actions, input recognition errors, and user errors. These differences were consistent across tasks, selection versus deselection actions, and naturally occurring versus experimentally injected input recognition errors. A multi-class deep neural network successfully discriminated between these three input events using only gaze dynamics, achieving an AUC-ROC-OVR score of 0.78. Together, these results demonstrate the utility of gaze in detecting interaction errors and have implications for the design of intelligent systems that can assist with adaptive error recovery.
Inter-Slice Mobility Management in 5G: Motivations, Standard Principles, Challenges and Research Directions (2020)

Mobility management in a sliced 5G network introduces new and complex challenges. In a network-sliced environment, user mobility has to be managed among not only different base stations or access technologies but also different slices. Managing user mobility among slices, or inter-slice mobility, motivates the need for new solutions. This article, presented as a tutorial, focuses on the problem of inter-slice mobility from the perspective of 3GPP standards for 5G. It provides a detailed overview of the relevant 3GPP standard principles. Accordingly, key technical gaps, challenges, and corresponding research directions are identified towards achieving seamless inter-slice mobility within the current 3GPP network slicing framework.
