Comprehensive Chemistry Designs in Porous SiOCH Film Stacks and Plasma Etching Gases for Damageless Cu Interconnects in Advanced ULSI Devices (2008)

High performance Cu dual-damascene (DD) interconnects without process-induced damages are developed in porous SiOCH stacks with the effective dielectric constant (k <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">eff</sub> ) of 2.95, in which a carbon (C)-rich molecular-pore-stacking (MPS) SiOCH film (k = 2.5) is stacked directly on an oxygen (O)-rich porous SiOCH (k = 2.7) film. The novel etch-stopperless structure is obtained by comprehensive chemistry design of C/O ratios in the SiOCH stack and the etching plasma of an Ar/N <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> /CF <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">4</sub> /O <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> gas mixture technique.

Combining multiresist mask process with immersion ArF photolithography, strictly controlled Cu DD interconnects with 180-nm pitched lines and 65-nm-diameter vias are obtained successfully, ready for the 300-mm fabrication.
Comparison of Acoustic Radiation Force Impulse Imaging Derived Carotid Plaque Stiffness With Spatially Registered MRI Determined Composition (2015)

Measurements of plaque stiffness may provide important prognostic and diagnostic information to help clinicians distinguish vulnerable plaques containing soft lipid pools from more stable, stiffer plaques. In this preliminary study, we compare in vivo ultrasonic Acoustic Radiation Force Impulse (ARFI) imaging derived measures of carotid plaque stiffness with composition determined by spatially registered Magnetic Resonance Imaging (MRI) in five human subjects with stenosis > 50%. Ultrasound imaging was implemented on a commercial diagnostic scanner with custom pulse sequences to collect spatially registered 2D longitudinal B-mode and ARFI images. A standardized, multi-contrast weighted MRI sequence was used to obtain 3D Time of Flight (TOF), T1 weighted (T1W), T2 weighted (T2W), and Proton Density Weighted (PDW) transverse image stacks of volumetric data. The MRI data was segmented to identify lipid, calcium, and normal loose matrix components using commercially available software. 3D MRI segmented plaque models were rendered and spatially registered with 2D B-mode images to create fused ultrasound and MRI volumetric images for each subject. ARFI imaging displacements in regions of interest (ROIs) derived from MRI segmented contours of varying composition were compared. Regions of calcium and normal loose matrix components identified by MRI presented as homogeneously stiff regions of similarly low (typically ≈ 1 μm) displacement in ARFI imaging. MRI identified lipid pools > 2 mm(2), found in three out of five subjects, presented as softer regions of increased displacement that were on average 1.8 times greater than the displacements in adjacent regions of loose matrix components in spatially registered ARFI images. This work provides early evidence supporting the use of ARFI imaging to noninvasively identify lipid regions in carotid artery plaques in vivo that are believed to increase the propensity of a plaque to rupture. Additionally, the results provide early training data for future studies and aid in the interpretation and possible clinical utility of ARFI imaging for identifying the elusive vulnerable plaque.
Bulldaggers, Pansies, and Chocolate Babies (2010)

Bulldaggers, Pansies, and Chocolate Babies shines the spotlight on historically neglected plays and performances that challenged early twentieth-century notions of the stratification of race, gender, class, and sexual orientation. On Broadway stages, in Harlem nightclubs and dance halls, and within private homes sponsoring rent parties, African American performers of the 1920s and early 1930s teased the limits of white middle-class morality. Blues-singing lesbians, popularly known as "bulldaggers," performed bawdy songs; cross-dressing men vied for the top prizes in lavish drag balls; and black and white women flaunted their sexuality in scandalous melodramas and musical revues. Race leaders, preachers, and theater critics spoke out against these performances that threatened to undermine social and political progress, but to no avail: mainstream audiences could not get enough of the riotous entertainment. James F. Wilson has based his rich cultural history on a wide range of documents from the period, including eyewitness accounts, newspaper reports, songs, and play scripts, combining archival research with an analysis grounded in a cultural studies framework that incorporates both queer theory and critical race theory. Throughout, he argues against the widely held belief that the stereotypical forms of black, lesbian, and gay show business of the 1920s prohibited the emergence of distinctive new voices. Figuring prominently in the book are African American performers including Gladys Bentley, Ethel Waters, and Florence Mills, among others, and prominent writers, artists, and leaders of the era, including Langston Hughes, Wallace Thurman, Zora Neale Hurston, and W. E. B. Du Bois. The study also engages with contemporary literary critics, including Henry Louis Gates and Houston Baker. "James F. Wilson uncovers fascinating new material on the Harlem Renaissance, shedding light on the oft-forgotten gay and lesbian contributions to the era's creativity and Civil Rights. Extremely well researched, compellingly written, and highly informative." —David Krasner, author of A Beautiful Pageant: African American Theatre, Drama, and Performance in the Harlem Renaissance, 1910-1927
Effects of Oral Administration of Interferon-alpha on Antibody Production in Mice with Induced Tolerance (1999)

In vivo systemic effects and the immunomodulating potential of the oral administration of murine interferon-alpha (IFN-alpha) were investigated through mRNA expression of both IFN-alpha-inducible factors, interferon regulatory factor-1 (IRF-1) and 2,5-adenylate synthetase [2-5(A) synthetase] and 2-5(A) synthetase enzymatic activity in spleen and antibody production. The daily administration of IFN-alpha (0.1, 1, 10, and 100 IU/body) for 1 week augmented IRF-1 and 2-5(A) synthetase mRNA expression levels, as well as 2-5(A) synthetase enzymatic activity in spleen cells but not in cervical lymph nodes. The in vivo immunomodulating potential of the oral administration of IFN-alpha was also evaluated through antibody production in mice with induced tolerance. Ovalbumin (OVA) was administered intraperitoneally (i.p.) to induce systemic antibody production on day 0 when OVA feeding was initiated. The OVA was fed every 2-3 days for a total of 14 doses to suppress serum antibody levels. Oral administration of murine IFN-alpha was initiated on day 0 and was continued for 5 consecutive days weekly for 5 weeks (24 doses). On every sampling date (days 10, 17, 24, and 32), specific antibody levels in the IFN-alpha-administered groups were significantly higher than those in the control (nonadministered) group. This was especially noted in early phases (days 10 and 17) of antibody production when the levels of antibody in serum from the IFN-alpha-administration groups were equivalent to those of the nontolerance group. Altogether, it is suggested that oral use of IFN-alpha can elicit immunomodulating actions (e.g., antibody levels) by affecting the systemic immune system(s).
Surface Amplification of L-Glutamate Using a Patterned Bienzymatic System for Biosensing Applications (2009)

Electronic sensing of neurotransmitter molecules is based on a diffusion-limited process, which requires the immobilization of biological recognition elements as close as possible to the active area of the sensor. Moreover, in many applications, the analyte concentration is very low. In particular, the in situ detection of neurotransmitter release from neurons is challenging due to the limited number of molecules secreted and their fast diffusion and reuptake immediately after release. In this paper, we present a method that allows for the local amplification of L-glutamate directly on the chip surface. Our approach is based on the surface patterning of a bienzymatic system consisting of glutamate oxidase (GLOD) and glutamic-pyruvate transaminase (GPT) that amplifies L-glutamate via a recycling process. The surface chemistry was optimized for maximal enzyme loading. The level of amplification was determined using a colorimetric assay. Coimmobilization of GLOD and GPT yielded at least a doubling of the signal, and increasing the surface concentrations of each enzyme led to amplification levels that approached those obtained in solution. We show that these enzymes can be patterned on substrates using a flip chip bonder for aligned microcontact printing. Furthermore, primary mouse hippocampal neurons were successfully cultured on these patterned surfaces and remained viable for at least five days. The enzymatic pattern was preserved on the substrate surface for the same time period. Lastly, amplification of L-glutamate released from neurons seven days in vitro was detected. Thus, we conclude that this bienzymatic system can ultimately be applied to biosensor surfaces for the in vitro detection of L-glutamate.
Complete sideband suppression in magic angle spinning solid-state nuclear magnetic resonance for arbitrary chemical shift anisotropies (1993)

A new expt. is presented for complete sideband suppression in magic angle spinning NMR expts. on solids. The method is based on the combination of a TOSS (total sideband suppression) sequence with its time-reversed counterpart; however, this method is more powerful than TOSS alone since it preserves the full spectral intensity for all chem. shift anisotropies and can even be applied to samples that feature an anisotropic distribution of crystallites.

ECSGlasses and EyePliances (2004)

We present ECSGlasses: wearable eye contact sensing glasses that detect human eye contact. ECSGlasses report eye contact to digital devices, appliances and EyePliances in the user's attention space. Devices use this attentional cue to engage in a more sociable process of turn taking with users. This has the potential to reduce inappropriate intrusions, and limit their disruptiveness. We describe new prototype systems, including the Attentive Messaging Service (AMS), the Attentive Hit Counter, the first person attentive camcorder eyeBlog, and an updated Attentive Cell Phone. We also discuss the potential of these devices to open new windows of interaction using attention as a communication modality. Further, we present a novel signal-encoding scheme to uniquely identify EyePliances and users wearing ECSGlasses in multiparty scenarios.
Interspecific Hybridization of Meiotic Parthenogenetic Meloidogyne chitwoodi and M. fallax (1997)

ABSTRACT Hybridization between two meiotic parthenogenetic species of root-knot nematodes, Meloidogyne chitwoodi and M. fallax, was investigated in two different crossing experiments on tomato plants grown in sand. The first experiment was a controlled cross between the two species. The second experiment was a bulk mating in a 1:1 mixture of two isolates. The haploid chromosome number of the parental isolates was n = 18. Successful interspecific hybridization was obtained, and the resulting hybrids produced egg masses. In eggs, cell division was observed, but most of them were without clear differentiation and consequently were sterile. Hatched F(2) juveniles were small in number, not viable, and showed morphological distortions. In the progeny of the isolate mixture of the bulk mating experiment, parental-type females of the two isolates were present in equal numbers, and 10% of all females were nonviable hybrids. Similar ratios of parental-type and hybrid females were detected in roots of test plants grown in soil from a field sample that contained a mixture of M. chitwoodi and M. fallax populations. In the controlled cross experiment, isozyme electrophoresis of malate dehydrogenase was applied to distinguish the two species and their hybrids. In the bulk mating experiment, malate dehydrogenase, esterase, and glucose 6-phosphate dehydrogenase were used as markers, two by two simultaneously on the same individual females, providing conclusive evidence for the occurrence of hybrids. This is the first report on interspecific hybridization in Meloidogyne. The possible role of interspecific hybridization in species differentiation and interspecific exchange of genetic material within Meloidogyne is discussed.
Security and protection architectures for large-scale content distribution (2002)

The Internet is increasingly being depended upon to provide large-scale content distribution. An important need is mechanisms to aid in the scalability of distribution services. These mechanisms include multicast, anycast, peer-to-peer, and overlay-based content distribution networks. 
As content distribution on the Internet becomes more pervasive and the value of the content being distributed increases, the security of this content and its distribution channels has become a main concern of content creators, owners, and providers. There have been significant advances in maturing the distribution mechanisms; however, there are a number of distinct security issues in these technologies. 
To address these problems, our research aims to develop flexible content protection architectures for large-scale content distribution. One focus of our research is the development of a content fingerprinting system that can provide theft deterrence in multicast and content distribution network environments while maintaining the scalability of these models. A second result of our work is a group access control architecture that addresses vulnerabilities that exist in multicast and anycast due to the open nature of the models. A third focus of our work is to develop a content protection architecture for decentralized peer-to-peer file-sharing systems where there is no central authority to enforce a security policy.
Performance of Genetically Modified Soybean Expressing the Cry1A.105, Cry2Ab2, and Cry1Ac Proteins Against Key Lepidopteran Pests in Brazil (2020)

The pyramided genetically modified (GM) soybean [Glycine max L. (Merr.)] MON87751 × MON87708 × MON87701 × MON89788, expressing Cry1A.105, Cry2Ab2, and Cry1Ac from Bacillus thuringiensis Berliner, was approved for commercial use in Brazil. We conducted laboratory, greenhouse, and field studies to assess the efficacy of this Bt soybean against key soybean lepidopteran pests. Neonates of Anticarsia gemmatalis (Hübner) (Lepidoptera: Erebidae), Chrysodeixis includens (Walker), and Helicoverpa armigera (Hübner) (Lepidoptera: Noctuidae) were exposed to Bt proteins in diet-overlay bioassays. MON87751 × MON87708 × MON87701 × MON89788 soybean and individual components were evaluated in laboratory (leaf disc), greenhouse (high artificial infestations), and in field conditions (natural infestations). Neonates of A. gemmatalis, C. includens, and H. armigera were highly susceptible to Cry1A.105 (LC50 from 0.79 to 48.22 ng/cm2), Cry2Ab2 (LC50 from 1.24 to 8.36 ng/cm2), and Cry1Ac (LC50 from 0.15 to 5.07 ng/cm2) in diet-overlay bioassays. In laboratory leaf disc bioassays and greenhouse trials, MON87751 × MON87708 × MON87701 × MON89788 soybean as well as the individual components were highly effective in controlling A. gemmatalis, C. includens, and H. armigera. Similarly, under field conditions, the pyramided genotypes expressing Cry1A.105, Cry2Ab2, and Cry1Ac were highly effective at protecting soybean against C. includens. We concluded that the individual Bt proteins expressed by GM soybean MON87751 × MON87708 × MON87701 × MON89788 killed all or nearly all the susceptible A. gemmatalis, C. includens, and H. armigera, fulfilling one important criterion for successfully delaying resistance to pyramided Bt crops.

Clinical Significance of Multiparametric Magnetic Resonance Imaging as a Preoperative Predictor of Oncologic Outcome in Very Low-Risk Prostate Cancer (2019)

Currently, multiparametric magnetic resonance imaging (mpMRI) is not an indication for patients with very low-risk prostate cancer. In this study, we aimed to evaluate the usefulness of mpMRI as a diagnostic tool in these patients. We retrospectively analyzed the clinical and pathological data of individuals with very low-risk prostate cancer, according to the NCCN guidelines, who underwent mpMRI before radical prostatectomy at our institution between 2010 and 2016. Patients who did not undergo pre-evaluation with mpMRI were excluded. We analyzed the factors associated with biochemical recurrence (BCR) using Cox regression model, logistic regression analysis, and Kaplan⁻Meier curve. Of 253 very low-risk prostate cancer patients, we observed 26 (10.3%) with BCR during the follow-up period in this study. The median follow-up from radical prostatectomy was 53 months (IQR 33⁻74). The multivariate Cox regression analyses demonstrated that the only factor associated with BCR in very low-risk patients was increase in the pathologic Gleason score (GS) (HR: 2.185, <i>p</i>-value 0.048). In addition, multivariate logistic analyses identified prostate specific antigen (PSA) (OR: 1.353, <i>p</i>-value 0.010), PSA density (OR: 1.160, <i>p</i>-value 0.013), and suspicious lesion on mpMRI (OR: 1.995, <i>p</i>-value 0.019) as the independent preoperative predictors associated with the pathologic GS upgrade. In our study, the pathologic GS upgrade after radical prostatectomy in very low-risk prostate cancer patients demonstrated a negative impact on BCR and mpMRI is a good prognostic tool to predict the pathologic GS upgrade. We believe that the implementation of mpMRI would be beneficial to determine the treatment strategy for these patients.

Activity of aortic chemoreceptors in the anaesthetized rat (1999)

1. It has been widely accepted that the rat aortic depressor nerve contains only baroreceptors. However, the experiments which have provided these negative data have employed whole aortic nerve recording. In the present study, the technical difficulties associated with recording single fibres in vivo, from the rat aortic nerve (diameter 25-50 microm), have been surmounted using a small tip, glass suction electrode technique. 2. Upon switching from normocapnic hyperoxia to hypercapnic hypoxia, irregularly firing units (n = 13) appeared and these were significantly excited by intravenous injections of sodium cyanide (20 microg) but not by rises in arterial blood pressure induced by methoxamine (an alpha1-adrenoreceptor agonist; 10 microg). Inhalation of 100 % oxygen rapidly and reversibly silenced, or profoundly reduced, ongoing activity. 3. Intravenous injection of phenylbiguanide (PBG; a 5-HT3 receptor agonist; 8 microg) strongly stimulated the chemoreceptors and was followed by a period of chemodepression (3-21 s). In contrast none of the single fibre baroreceptors recorded (n = 15) were excited by PBG but all significantly increased their discharge in response to the increases in arterial blood pressure associated with methoxamine and cyanide. Both the excitatory and inhibitory effects of PBG on the chemoreceptor fibres were abolished by ondansetron (a 5-HT3 receptor antagonist: 1 mg kg-1 i.v.; n = 5 animals) whilst the chemoexcitatory action of cyanide was preserved. 4. It is concluded that there are chemoreceptor afferents contained in the aortic nerve of the Sprague-Dawley rat. The 5-HT3 receptor appears not to be a pre-requisite for aortic body chemoexcitation.
Real-time Grid Impedance Measurement of Three-Phase Micro-grid System in d-q Frame using Quadratic Residue Ternary Sequence (QRTS) (2019)

Thee-phase micro-grid systems with tightly regulated power converters are prone to interactions and causes small signal instability. The regulated converters behave like constant power loads (CPLs), and cause instability. Adaptive controllers can be used to ensure stable operation of the system, and the controllers require real-time grid impedance measurement. In this paper, a computationally effective impedance measurement technique using the Quadratic Residue Ternary Sequence (QRTS) has been proposed. The QRTS signal is a class of Pseudo Random Binary Sequence (PRBS), which is used for system identification in control engineering. The proposed signal has low crest factor compared to the conventional Newman's multi-sine signal. The effectiveness of the proposed impedance measurement technique using QRTS signal has been tested in MATLAB/Simulink simulation environment for a three-phase micro-grid system. The results have been validated with the conventional Newman's multi-sine perturbation, and results shows that the QRTS is an effective perturbation method to measure real-time grid impedance.
A Low-Computational Approach on Gaze Estimation With Eye Touch System (2013)

Among various approaches to eye tracking systems, light-reflection based systems with non-imaging sensors, e.g., photodiodes or phototransistors, are known to have relatively low complexity; yet, they provide moderately accurate estimation of the point of gaze. In this paper, a low-computational approach on gaze estimation is proposed using the Eye Touch system, which is a light-reflection based eye tracking system, previously introduced by the authors. Based on the physical implementation of Eye Touch, the sensor measurements are now utilized in low-computational least-squares algorithms to estimate arbitrary gaze directions, unlike the existing light reflection-based systems, including the initial Eye Touch implementation, where only limited predefined regions were distinguished. The system also utilizes an effective pattern classification algorithm to be able to perform left, right, and double clicks based on respective eye winks with significantly high accuracy. In order to avoid accuracy problems for sensitive sensor biasing hardware, a robust custom microcontroller-based data acquisition system is developed. Consequently, the physical size and cost of the overall Eye Touch system are considerably reduced while the power efficiency is improved. The results of the experimental analysis over numerous subjects clearly indicate that the proposed eye tracking system can classify eye winks with 98% accuracy, and attain an accurate gaze direction with an average angular error of about 0.93 °. Due to its lightweight structure, competitive accuracy and low-computational requirements relative to video-based eye tracking systems, the proposed system is a promising human-computer interface for both stationary and mobile eye tracking applications.
