Effects of N Incorporation on Electron Traps at SiO<sub>2</sub>/SiC Interfaces (2012)

Temperature dependent capacitance-voltage (C-V) and constant capacitance transient spectroscopy (CCDLTS) measurements have been performed to investigate the role of N in improving the transport properties of 4H-SiC MOS transistors. The higher channel mobility in the N pre-implanted transistors is due at least in part to activation of a small fraction of the implanted N near the SiO 2 /SiC interface as donors in SiC during oxidation, thus reducing the effects of interface trapping. In addition, the absence of oxidation-induced near-interface defects, which were observed in NO-annealed capacitors, may contribute to the improved mobility in N pre-implanted transistors.
Estimation of Nitrogen Concentration Distribution for Carbonitrided SUJ2 Steel (2007)

We have been investigating the nitrogen penetration mechanism carbonitriding into high carbon chromium bearing steel JIS-SUJ2 on carbonitriding processes. Assuming that the penetration mechanisms of nitrogen and carbon are the same, we developed a calculation method in order to estimate nitrogen concentration distribution profiles, which are based on our through experimental data. In our method, the dependencies on carbon activity, partial pressures of H2 and undecomposed NH3, and diffusion coefficient of nitrogen are taken into consideration. It was confirmed that the nitrogen concentration distribution profiles predicted by our method agreed well with the experiment results under various conditions. Hence, we deduce that our method is effective in a practical range on carbonitriding processes.
Development of ALD HfZrO[sub x] with TDEAH/TDEAZ and H[sub 2]O (2010)

In this work we report on the development of the atomic layer deposition (ALD) process with tetrakisdiethylamino (TDEA) hafnium/zirconium (TDEAH/TDEAZ) and . A nanolaminar structure approach is used to grow by alternating and ALD reaction cycles at . The film thickness increases linearly with the number of ALD cycles. Compared to the halide based process, the process with TDEA precursors and yields a lower temperature window, an initial growth insensitive toward the starting surfaces, and a fast film closure on the hydrofluoric acid-last surface. The Zr content, measured by Rutherford backscattering increases linearly with the cycle ratio of . The as-deposited films are amorphous and crystallize after a postdeposition anneal. Depending on the film composition a different crystalline phase is formed, ranging from monoclinic to tetragonal with increasing Zr content. Using instead of not only reduces the interfacial oxide regrowth during deposition, which allows for a thinner interfacial layer and improves the interfacial oxide scalability, but also results in a lower C content in the deposited films. Finally, complementary metal oxide semiconductor transistor using as gate dielectric are fabricated for the evaluation of device performance. These results show that all considered splits with as gate dielectric yield a similar equivalent oxide thickness-gate leakage current performance and (low) gate current leakage level. The data reported in this paper demonstrates that ALD grown based on and is a promising gate dielectric for subnanometer equivalent oxide thickness scaling.
Dispositional optimism as predictor of outcome in short- and long-term psychotherapy (2017)

Objectives
Dispositional optimism predicts various beneficial outcomes in somatic health and treatment, but has been little studied in psychotherapy. This study investigated whether an optimistic disposition differentially predicts patients’ ability to benefit from short-term versus long-term psychotherapy.

Design
A total of 326 adult outpatients with mood and/or anxiety disorder were randomized into short-term (solution-focused or short-term psychodynamic) or long-term psychodynamic therapy and followed up for 3 years.

Methods
Dispositional optimism was assessed by patients at baseline with the self-rated Life Orientation Test (LOT) questionnaire. Outcome was assessed at baseline and seven times during the follow-up, in terms of depressive (BDI, HDRS), anxiety (SCL-90-ANX, HARS), and general psychiatric symptoms (SCL-90-GSI), all seven follow-up points including patients’ self-reports and three including interview-based measures.

Results
Lower dispositional optimism predicted faster symptom reduction in short-term than in long-term psychotherapy. Higher optimism predicted equally rapid and eventually greater benefits in long-term, as compared to short-term, psychotherapy.

Conclusions
Weaker optimism appeared to predict sustenance of problems early in long-term therapy. Stronger optimism seems to best facilitate engaging in and benefiting from a long-term therapy process. Closer research might clarify the psychological processes responsible for these effects and help fine-tune both briefer and longer interventions to optimize treatment effectiveness for particular patients and their psychological qualities.

Practitioner points
Weaker dispositional optimism does not appear to inhibit brief therapy from effecting symptomatic recovery.
Patients with weaker optimism do not seem to gain added benefits from long-term therapy, but instead may be susceptible to prolonged psychiatric symptoms in the early stages of long-term therapy.
Effects of Foot Orthoses on Center-of-Pressure Patterns in Women (1989)

The purpose of this study was to determine the effects of foot orthoses on the pattern of center of pressure in women with forefoot deformities during walking. Nine subjects with a forefoot varus and nine subjects with a forefoot valgus walked across a force platform three times for each of the following five treatment conditions: 1) barefoot, 2) shoes only, 3) rigid orthoses with shoes, 4) semi-rigid orthoses with shoes, and 5) soft orthoses with shoes. Force data were analyzed to determine the area under the center-of-pressure curve. A significant omnibus F ratio was obtained for treatments (p less than .001) and the deformity X treatments interaction (p less than .05) using a two-factor, mixed analysis of variance for repeated measures. Tukey's post hoc comparisons for the Varus Group resulted in significant differences (p less than .05) between the following treatment conditions: 1) barefoot and shoes only, 2) barefoot and rigid orthoses with shoes, 3) barefoot and semi-rigid orthoses with shoes, and 4) barefoot and soft orthoses with shoes. Tukey's post hoc comparisons for the Valgus Group resulted in significant differences (p less than .05) between the following treatment conditions: 1) barefoot and rigid orthoses with shoes, 2) barefoot and semi-rigid orthoses with shoes, and 3) barefoot and soft orthoses with shoes. The shoes-only treatment condition, in comparison with the barefoot condition, significantly reduced the center-of-pressure area for the Varus Group only.(ABSTRACT TRUNCATED AT 250 WORDS)
Biological categories and border controls: the revival of eugenics in anti‐immigration rhetoric (1998)

Looks at the contemporary debate on US immigration, focusing particularly on the increasing articulation of eugenics. Notes that, at times of economic and moral crisis, biological generalizations tend to resurface to provide support for the existing system of privilege and rights, and that the information superhighway provides the perfect vehicle for rapidly spreading beliefs and information. Addresses three specific issues – the genetically determined traits and behaviours of specific racial groups, culture as an expression of biological characteristics, and immigration destroying the racial purity of American society. Outlines briefly US history of immigration. Airs the current concerns on US immigration – pinpointing that concern lies not in immigration per se., which has declined in the last decade, but in the changing national origin of new immigrants, that is immigrants are now mainly Latin American or Asian, which is seen as a threat to Anglo‐Saxon hegemony. Refers to the work of the Pioneer Fund, exploring human variation through the racial basis of intelligence and propensity to violence and/or crime. Claims that scientific language has been adapted to reinforce worries about immigration reducing the supremacy of America’s culture.
INCIDENCE, MANAGEMENT, AND OUTCOME OF FEMORAL SHAFT FRACTURE (1994)

31% of patients were treated nonsurgically with higher associated mortality. These results support "early" surgical fixation, which can shorten hospital stay without increasing mortality regardless of overall injury severity. The trend toward higher mortality in severely injured patients operated on within 1 day of admission suggests that this group warrants further study and individualized management.
Data from Expansion of a BDCA1<sup>+</sup>CD14<sup>+</sup> Myeloid Cell Population in Melanoma Patients May Attenuate the Efficacy of Dendritic Cell Vaccines (2023)

&lt;div&gt;Abstract&lt;p&gt;The tumor microenvironment is characterized by regulatory T cells, type II macrophages, myeloid-derived suppressor cells, and other immunosuppressive cells that promote malignant progression. Here we report the identification of a novel BDCA1&lt;sup&gt;+&lt;/sup&gt;CD14&lt;sup&gt;+&lt;/sup&gt; population of immunosuppressive myeloid cells that are expanded in melanoma patients and are present in dendritic cell–based vaccines, where they suppress CD4&lt;sup&gt;+&lt;/sup&gt; T cells in an antigen-specific manner. Mechanistic investigations showed that BDCA1&lt;sup&gt;+&lt;/sup&gt;CD14&lt;sup&gt;+&lt;/sup&gt; cells expressed high levels of the immune checkpoint molecule PD-L1 to hinder T-cell proliferation. While this BDCA1&lt;sup&gt;+&lt;/sup&gt;CD14&lt;sup&gt;+&lt;/sup&gt; cell population expressed markers of both BDCA1&lt;sup&gt;+&lt;/sup&gt; dendritic cells and monocytes, analyses of function, transcriptome, and proteome established their unique nature as exploited by tumors for immune escape. We propose that targeting these cells may improve the efficacy of cancer immunotherapy. &lt;i&gt;Cancer Res; 76(15); 4332–46. ©2016 AACR&lt;/i&gt;.&lt;/p&gt;&lt;/div&gt;
Gas detection and identification using MEMS TOF mass spectrometer (2013)

This work reports on both the micro fabrication of a miniaturized MEMS ion source and its utilization as a simple Time-Of-Flight (TOF) MEMS mass spectrometer for gas detection. Microelectronic manufacturing process is used for the fabrication. The ion source and the analyzer are manufactured simultaneously and collectively. The ionizer generates one of the highest current for an integrated ion source. Mass spectra of several gases, such as ethanol, argon, krypton and xenon have been obtained.
Genomic Copy Number Analysis ofHER2-Equivocal Breast Cancers (2016)

A combination of hyperdiploidy and segmental copy number gains contributes to HER2 ISH-equivocal results in most breast cancers. Cases in which HER2 copy number gain is not corroborated by genomic analysis suggest the presence of other contributing variables influencing ISH results. Genomic copy number analysis also implicates non-HER2 oncogenic drivers in many cases that are HER2 equivocal.

Modeling and Evaluation of Paper Machine Coater Sections Part 1: 1-Coater Section and Tension Setpoints (2018)

Coater sections are challenging to tune during the commissioning of a paper machine. This paper presents a detailed mechanical-electrical model of a 1-coater section, which includes a linear, operating point model of the sheet in the different spans, all the drivetrain components, and the vector-controlled ac drives. The sheet model considers tail widening as well as the effect of coating and drying on the sheet elastic constant, activation of the torque current control, and the beginning of coating. The developed model allows for complete evaluation of the different transient events including paper slack due to load impacts. Results show that the best performance of the drives is obtained operating the spans with even sheet tensions, which reduces and/or eliminates the operation of the drives in regeneration or braking zones.
Photoacoustic imaging biomarkers for monitoring biophysical changes during nanobubble-mediated radiation treatment (2020)

The development of novel anticancer therapies warrants the parallel development of biomarkers that can quantify their effectiveness. Photoacoustic imaging has the potential to measure changes in tumor vasculature during treatment. Establishing the accuracy of imaging biomarkers requires direct comparisons with gold histological standards. In this work, we explore whether a new class of submicron, vascular disrupting, ultrasonically stimulated nanobubbles enhance radiation therapy. <i>In vivo</i> experiments were conducted on mice bearing prostate cancer tumors. Combined nanobubble plus radiation treatments were compared against conventional microbubbles and radiation alone (single 8 Gy fraction). Acoustic resolution photoacoustic imaging was used to monitor the effects of the treatments 2- and 24-hs post-administration. Histological examination provided metrics of tumor vascularity and tumoral cell death, both of which were compared to photoacoustic-derived biomarkers. Photoacoustic metrics of oxygen saturation reveal a 20 % decrease in oxygenation within 24 h post-treatment. The spectral slope metric could separate the response of the nanobubble treatments from the microbubble counterparts. This study shows that histopathological assessment correlated well with photoacoustic biomarkers of treatment response.
Short-term wind power ramp forecasting with empirical mode decomposition based ensemble learning techniques (2017)

Wind is a clean and renewable energy source with huge potential in power generation. However, due to the intermittent nature of the wind, the power generated by wind farms fluctuates and often has large ramps, which are harmful to the power grid. This paper presents algorithms to forecast the ramps in the wind power generation. The challenges of accurate wind power ramp forecasting are addressed. Wind power ramp and power ramp rate are defined. An ensemble method composed of empirical mode decomposition (EMD), kernel ridge regression (KRR) and random vector functional link (RVFL) network is employed to forecast the wind power ramp and the ramp rate. The performance of the proposed method is evaluated by comparing with several benchmark models based on both accuracy and efficiency. Possible future research directions are also identified.
Fundamental Aspects of the Science and Engineering of Oil Spill Dispersant Systems: An Overview of Recent Research Activities of the Gulf of Mexico Research Initiative-funded CMEDS Project (2014)

ABSTRACT Upon consideration of dispersant-related research, both before and after the Macondo Well oil release, it can be divided into two general categories: (1) the fundamentals of how dispersants work and the effects that may result from their use (e.g., physicochemical and transport characteristics of drops, bubbles, hydrates, surfactants), and (2) an applied focus that has emphasized the design of new dispersants or an enhancement of the performance of those products that are currently available. While there is an extensive amount of data relating to dispersants, a main focus has been on the demonstration of their effectiveness in bench tests and examination of the toxicity of dispersants and dispersed oil. As a result, there is a need for an enhanced understanding of dispersant and dispersed oil thermodynamics and their fate and transport, with a goal to translate the science and engineering to the development of new, effective dispersant systems. The focus of the work to be discussed addresses the following areas: Formation of small oil droplets: Widely dispersed stable oil droplets in the water column are easily accessible to microbes and therefore highly susceptible to degradation. It is important therefore, to understand the fundamental mechanisms of oil breakup and colloidal stabilization in order to develop new and effective dispersants. Dispersant-related processes under deep sea conditions: Current dispersants have been developed for surface spills. The efficacy of such formulations when applied at the high pressures and low temperatures representative of deep ocean release has not been systematically studied. Because of concomitant gas release at the discharge point, and the pressures involved, the liquid droplet is essentially a gas-expanded liquid which could behave quite differently when treated with dispersant components depending upon how they partition at the phase interfaces, i.e., gas/water, gas/oil, oil/water. Fluid mechanics of stabilized oil droplets: Droplet transport, as influenced by all thermodynamic variables of relevance under deep sea conditions, is being studied. Droplet interactions with solid particulates: A better understanding of these processes, either in marine sediments or in the water column, will help predict the environmental fate of the droplets. Development of alternative dispersants: Based on the knowledge gained with respect to the fundamentals, a key goal is the systematic translation of that understanding to the development of new and improved materials. This paper summarizes recent work of a collaborative research effort involving investigators from 22 universities, with particular emphasis on increasing the understanding of the science and engineering of oil spill dispersants.
Abnormal Four-Membered Ring Formation in Intramolecular Radicalic Cyclization. High Stability of the Alkyl Radical Substituted with Methylthio and p-Tolylsulfonyl Groups (1992)

Abstract Treatment of 5-iodo-1-(methylthio)-1-(p-tolylsulfonyl)-1-pentene with (n-Bu)3SnH and AIBN gave [(methylthio)(p-tolylsulfonyl)methyl]cyclobutane. This is due to the stability of an intermediary radical attached to methylthio and p-tolylsulfonyl groups.
Interactive shape metamorphosis (1995)

Image metamorphoses (morphing) is a powerful and easy-to-use tool for generating new 2D images from existing 2D images. In recent years morphing has become popular as an artistic tool and is used extensively in the entertainment industry. In this paper we describe a new technique for controlled, feature-based metamorphosis of certain types of surfaces in 3-space; it applies well-understood 2D methods to produce shape metamorphosis between 3D models in a 2D parametric space. We also describe an interactive implementation on a parallel graphics multicomputer, which allows the user to define, modify and examine the 3D morphing process in real time.

CALCIUM‐DEPENDENT RELEASE OF EXOGENOUSLY LOADED γ‐AMINO‐[U‐14C]BUTYRATE FROM SYNAPTOSOMES: TIME COURSE OF STIMULATION BY POTASSIUM, VERATRIDINE, AND THE CALCIUM IONOPHORE, A23187 (1976)

Abstract —Synaptosomes which had taken up [ 14 C]GABA were applied to a filter and rapidly perfused with various solutions in order to study the time course of release of this putative transmitter and the characteristics of its release. Depolarization of the synaptosomes with veratridine or 56mM‐K + or pretreatment with the Ca 2+ ionophore, A23187, increased the calcium‐dependent efflux of [ 14 C]GABA. Release of [ 14 C]GABA was increased by Ca 2+ within 0.3 s of exposure, and the maximal release rate was not maintained for longer than 0.6 s. The reduction in the rate of release was not attributable to a decrease in calcium influx, but rather appeared to reflect fatigue at some subsequent stage in release. Stimulation by 56mM‐K + also elicited a calcium‐independent increase in the efflux of radioactive GABA, which appeared to arise in part from subcellular particles other than synaptosomes.
