Spatial and Temporal Distributions of a Gaseous Pollutant During Simulated Preventive Maintenance and Pipe Leaking Events in a Working Cleanroom (2009)

Sulfur hexafluoride (SF <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">6</sub> ) of > 99.9% in purity was artificially released to simulate the emission sources in the etching/thin-film area of a working cleanroom in a semiconductor fab at the rate of 492 g/h. The temporal and spatial dispersion patterns of the gas pollutant were studied during the simulated preventive maintenance (PM) and pipe leaking exhaust events experimentally and numerically. Three mobile Fourier transform infrared spectrometers (FTIRs, detection limit: 10 ppb) were used simultaneously to measure the real time SF <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">6</sub> concentrations in different locations of the etching/thin-film area of the cleanroom. An additional open-path FTIR with very low detection limit of 0.4 ppb was installed before the recirculation duct in the lithography area to monitor if the pollutant drifted from the etching/thin-film area to the lithography area. The results show that the 3-D numerical model predicts the unsteady gas concentration accurately in both the peak concentration and the time required to reach the peak concentration. Due to high dilution of the pollutant in the cleanroom, the current gas sensors may not be sensitive enough and a better monitoring system and strategy is needed to protect workers from injury and ensure good product yield. The well-mixed model predicts the peak pollutant concentrations within a reasonable range which is 0.34-1.33 times the experimental values except when the monitored distance is very close to the release point. Although it is not able to predict the time required to reach the peak concentration and the time for the concentration to drop below a small level, the simple well-mixed model can be used to obtain an estimation of the peak concentration quickly when the emission rate and the ventilation condition of the cleanroom are different than the current study.
Fotemustine in treating malignant glioma (2000)

AIM: To observe clinical results of fotemustine chemotherapy in malignant gliomas. METHODS: Thirty patients of adult operated malignant gliomas were treated with fotemustine 100 mg·m -2 intravenous infusion once a week for 3 consecutive weeks followed by a 5 wk rest period. Maintenance treatment consisted of one infusion every 3 wk, for 1×5 time. Antitumoral activity were investigated by comparing CT or MRI scanning in pre and postchemotherapy. Toxicity was evaluated by WHO grade system. RESULTS: In 30 patients, objective control in 6 patients(20 %), stable control in 17 patients (57 %), effectiveness in 7 patients (23 %). Haematological and liver toxicity were transient and reversible. Leucopenia was frequent (40 %), nausea and vomiting were common and mild. CONCLUSION: Fotemustine was a safe and effective drug for chemotherapy of malignant glioma.

Electrolyzed Water as a Novel Sanitizer in the Food Industry: Current Trends and Future Perspectives (2016)

Electrolyzed water (EW) has gained immense popularity over the last few decades as a novel broad-spectrum sanitizer. EW can be produced using tap water with table salt as the singular chemical additive. The application of EW is a sustainable and green concept and has several advantages over traditional cleaning systems including cost effectiveness, ease of application, effective disinfection, on-the-spot production, and safety for human beings and the environment. These features make it an appropriate sanitizing and cleaning system for use in high-risk settings such as in hospitals and other healthcare facilities as well as in food processing environments. EW also has the potential for use in educational building, offices, and entertainment venues. However, there have been a number of issues related to the use of EW in various sectors including limited knowledge on the sanitizing mechanism. AEW, in particular, has shown limited efficacy on utensils, food products, and surfaces owing to various factors, the most important of which include the type of surface, presence of organic matter, and type of tape water used. The present review article highlights recent developments and offers new perspectives related to the use of EW in various areas, with particular focus on the food industry.
Experiments in isolated word recognition using noisy speech (2005)

A series of experiments were performed to determine (1) the effects of using an energy-based endpoint detector and a conventional isolated word recognition system when the input speech is noisy and (2) the effects of placing a noise suppression prefilter in tandem with the word recognizer in an attempt to remove the noise prior to recognition. It was found that the system consisting of the prefilter working in tandem with the word recognizer increased word recognition accuracy.
Crystal structure determination at 2.3 A of recombinant human dihydrofolate reductase ternary complex with NADPH and methotrexate-gamma-tetrazole. (1992)

The crystal structure of the methotrexate-gamma-tetrazole (MTXT)-NADPH ternary complex with recombinant human dihydrofolate reductase (DHFR) has been determined and refined to R = 15.9% for 7003 data from 10.0 to 2.3 A resolution for the R3 lattice. Interpretation of difference Fourier electron density maps revealed that the cofactor NADPH is bound in an extended conformation, and the closest contact between cofactor and inhibitor is 3.1 A, between N(5) of the MTXT pteridine ring and the nicotinamide C(4) which transfers a hydride during the enzyme-catalyzed reaction. As in other DHFR complexes, MTXT is interpreted as protonated at N(1) by Glu-30, and the 2-amino group is hydrogen bonded to a structurally conserved water which also interacts with Glu-30 and Thr-136. The 4-amino group of MTXT hydrogen bonds to the carbonyl of Ile-7 and the phenolic hydroxyl of Tyr-121, and the alpha-carboxylate forms a salt bridge with the conserved Arg-70. In this structure, the amide carbonyl forms two hydrogen bonds with Asn-64 and a water molecule, whereas the gamma-tetrazole ring does not interact directly with the enzyme. The largest changes in the secondary structure on formation of the ternary complex involve the fold of a flexible loop near residues 40-46, and to a lesser extent the helical region near residues 102-109 and the beta-sheet regions near residues 71-75 and 157-159.
Leakage current, reliability characteristics, and boron penetration of ultra-thin (32-36 Å) O/sub 2/-oxides and N/sub 2/O/NO oxynitrides (2002)

In this paper, we investigate the effects of BF/sub 2/-implantation into the Si substrates and boron penetration from P/sup +/ poly gate on initial oxide leakage current and reliability of ultra-thin gate oxides (O/sub 2/ and N/sub 2/O/NO oxynitrides with thickness of 32-36 /spl Aring/). It is demonstrated that N/sub 2/O growth is less susceptible to substrate conditions than O/sub 2/ growth. Moreover, N/sub 2/O-oxides exhibit lower initial leakage current than O/sub 2/-oxides, which is very important for low power applications.

Structurally Enhanced Self-Plasticization of Poly(vinyl chloride) via Click Grafting of Hyperbranched Polyglycerol (2016)

A highly self-plasticized poly(vinyl chloride) (PVC) is demonstrated for the first time via click grafting of hyperbranched polyglycerol (HPG). The plasticizing effect of the grafted HPG on PVC is systematically investigated by various analytical methods. The amorphous and bulky dendritic structure of HPG efficiently increases the free volume of the grafted PVC, which leads to a remarkably lower glass transition temperature comparable to that of the conventional plasticized PVC. Viscoelastic analysis reveals that HPG considerably improves the softness of the grafted PVC at room temperature and promotes the segmental motion in the system. The HPG-grafted PVC films exhibit an exceptional stretchability unlike the mixture of PVC and HPG because the covalent attachment of HPG to PVC allows it to maintain its homogeneous and well-organized architecture under tensile stretching. The work provides valuable insights into the design of highly flexible and stretchable polymeric materials by means of introducing hyperbranched side chains.
Use of a large Foley catheter balloon to control postpartum hemorrhage resulting from a low placental implantation. A report of two cases. (1985)

In two cases postpartum hemorrhage resulted from placental implantation in the noncontractile cervical segment of the uterus. The hemorrhage was controlled successfully by inflating a large Foley catheter balloon with 60 ml of saline inside the cervical canal. The tamponade was the only therapy necessary. In some cases this technique may be useful in slowing the bleeding while stabilizing the patient and preparing for definitive treatment.

Abstract 328: Targeting Mcl-1 enhances DNA replication stress sensitivity for cancer therapy (2018)

Abstract DNA double-strand breaks (DSBs) are mainly repaired by homologous recombination (HR) and non-homologous end-joining (NHEJ) pathways. Here we report that Mcl-1 acts as a functional switch in pathway choice between HR and NHEJ. Mcl-1 was cell cycle-regulated, with expression peaking in S/G2 phase when HR occurred. Endogenous Mcl-1 depletion reduced HR and enhanced NHEJ. Mcl-1 overexpression resulted in a net increase in HR over NHEJ. Mcl-1 directly interacted with Ku via its BH1 and BH3 domains, which are required for Mcl-1 to inhibit Ku-mediated NHEJ and promote Mre11 complex-mediated DNA resection and HR-dependent DSB repair. Using the Mcl-1 BH1 domain (aa256-265) as docking site, we identified a novel small molecule, MI-223, that directly bound to BH1 and blocked Mcl-1-stimulated HR DNA repair leading to a significant sensitization of cancer cells to hydroxyurea- or olaparib-induced DNA replication stress. Combined treatment with MI-223 and hydroxyurea or olaparib exhibited a strong synergy against lung cancer in vivo. This mechanism-driven combination of agents provides a highly attractive therapeutic strategy to improve lung cancer outcome.

A preliminary investigation of local tomography for megavoltage CT imaging (2003)

We investigate the problem of reconstructing a two‐dimensional (2‐D) cross‐sectional image of a tumor volume from a set of truncated MV projections that are produced by radiation therapy treatment beams. Our proposed approach is conceptually distinct from previously investigated approaches in that it utilizes a noniterative local tomography reconstruction algorithm. A local tomography reconstruction algorithm is implemented and systematically investigated using several sets of simulated and experimental MV projection data. We demonstrate that the conventional (nonlocal) filtered backprojection reconstruction algorithm cannot, in general, accurately reconstruct the edges and boundaries of low‐contrast features from truncated MV projection data. We demonstrate that the local tomography algorithm is not adversely affected by projection truncation and can reconstruct accurately the boundaries of low‐contrast structures within the region of interest from truncated MV projections.
Prediction of Finished Weight and Shrinkage of Cotton Knits— The Starfish Project (1983)

The "Starfish" project is a long term program of applied research that attempts to provide a sufficiently rigorous working method and a sufficiently comprehensive data base so that a rational system may gradually be developed for reliably predicting the shrinkage and dimensional properties of finished, knitted cotton fabrics. This intro ductory report presents the general outline and philosophy of the project, and sum marizes some of the main areas of progress after the first five years, so that subsequent publications of detailed results may be seen in context.

Atomic force microscopy for the determination of refractive index profiles of optical fibers and waveguides: A quantitative study (1997)

The use of preferential etching and atomic force microscopy to measure refractive index profiles of optical fibers is investigated. Both the etch rate and the position of lateral features are shown to be independent of etch time. An elliptical core fiber was studied and the resultant profile was found to be in qualitative agreement with the preform index profile. It is shown, however, that the ellipticity of the core has changed during the drawing process. The method was extended to fluorine and germanium doped planar waveguides and the results correlated with the fabrication process.
Achievement of zero temperature coefficient of resistance with RuO<i>x</i> thin film resistors (1997)

The temperature coefficient of resistance (TCR) for an as-deposited RuO2.2 thin film resistor changes from −131.6 to 1007.95 ppm/°C after the annealing at 600 °C for 30 min. Typically, a near zero TCR about 0±0.12 ppm/°C can be obtained after annealing at 300 °C for 30 min in an Ar ambient. The changes of TCR from negative to positive is attributed to the grain growth of RuOx films from fine grain (30–40 Å) to a larger one (500–800 Å) during the annealing process. Rutherford backscattering spectroscopy and in situ x-ray photoemission spectroscopy show that the ratio of O/Ru in the RuOx film decreases from 2.2 to 2.0, due to the out diffusion of oxygen during the annealing process, which is independent of the changes in TCR.

What is the global burden of visual impairment? (2006)

The actual burden of visual impairment worldwide, including that caused by uncorrected refractive error, is substantially higher than the commonly quoted WHO estimate that is based on best-corrected visual acuity. We suggest that the indicative estimate of 259 million persons with visual impairment worldwide, which includes 42 million blind with visual acuity less than 3/60 in the better eye, be used for further planning of the VISION 2020 initiative instead of the often quoted 161 million estimate that includes 37 million blind.
An efficient kernel-based implementation of POSIX threads (1994)

This paper describes the kernel-based implementation of POSIX Threads (Pthreads) in the DG/UXTM operating system. The implementation achieves time efficiency by using a general-purpose trap mechanism, known as a Kernel Function Call (KFC), that carries an order of magnitude less overhead than a traditional system call. On a 50 MHz Motorola MC88110, the implementation can create and exit a thread (with the associated context switch) in 8.1 microseconds and yield to another thread in 4.0 microseconds. The implementation also achieves space efficiency by paging and decoupling bulky data structures.

The advantages of a kernel-based implementation include design simplicity, less code redundancy, optimization of global (interprocess) operations, avoidance of inopportune preemption, and global semantic flexibility. The disadvantage is a monolithic design that lacks user-level flexibility.
A theoretical and experimental study of a microwave plasma closing switch (2002)

Summary form only given. We have demonstrated experimentally that it is feasible to construct a microwave plasma closing switch by using a cylindrical coaxial line structure. A theoretical modeling was later presented at the APS meeting. This paper represents the revised version of both the theoretical and experimental studies on the same topics. Theoretically, the cylindrical coaxial line structure can be modeled by a very simple equivalent electrical circuit consisting only of resistors, capacitors, and inductors. The mathematical formulation obtained from such a circuit can explain our experimental observation very successfully.
Passive paths for networks (1991)

Camelina seed transcriptome: a tool for meal and oil improvement and translational research (2013)

Camelina (Camelina sativa), a Brassicaceae oilseed, has received recent interest as a biofuel crop and production platform for industrial oils. Limiting wider production of camelina for these uses is the need to improve the quality and content of the seed protein-rich meal and oil, which is enriched in oxidatively unstable polyunsaturated fatty acids that are deleterious for biodiesel. To identify candidate genes for meal and oil quality improvement, a transcriptome reference was built from 2047 Sanger ESTs and more than 2 million 454-derived sequence reads, representing genes expressed in developing camelina seeds. The transcriptome of approximately 60K transcripts from 22 597 putative genes includes camelina homologues of nearly all known seed-expressed genes, suggesting a high level of completeness and usefulness of the reference. These sequences included candidates for 12S (cruciferins) and 2S (napins) seed storage proteins (SSPs) and nearly all known lipid genes, which have been compiled into an accessible database. To demonstrate the utility of the transcriptome for seed quality modification, seed-specific RNAi lines deficient in napins were generated by targeting 2S SSP genes, and high oleic acid oil lines were obtained by targeting FATTY ACID DESATURASE 2 (FAD2) and FATTY ACID ELONGASE 1 (FAE1). The high sequence identity between Arabidopsis thaliana and camelina genes was also exploited to engineer high oleic lines by RNAi with Arabidopsis FAD2 and FAE1 sequences. It is expected that these transcriptomic data will be useful for breeding and engineering of additional camelina seed traits and for translating findings from the model Arabidopsis to an oilseed crop.
Correlation between measured surface and endocardial electrical signals of heart (2002)

The purpose of the present study was to determine whether the dynamicity of QT-interval, obtained from the standard ECG is comparable with the MAP duration changes. Three different study protocols were used for signal registration at spontaneous, fixed paced and incrementally paced heart rates. The results demonstrated high correlation between the surface QT-interval and MAP duration at various heart rates. The findings afford the opportunity to use QT-interval measured from surface ECG for modelling processes requiring endocardial electrogram registration.
