Bragg gratings in polarization-maintaining, large-area higher-order-modes fiber (2018)

We report on the inscription of Bragg gratings in optical-fibers designed for carrying polarization-maintained (PM) large-effective-area, higher-order-modes. We find that the Bragg gratings offer a convenient and superior platform for complete characterization of PM-multimode fibers.
Large Increase in External Quantum Efficiency by Dihedral Angle Tuning in a Sky‐Blue Thermally Activated Delayed Fluorescence Emitter (2019)

Abstract Efficient and stable blue emitters for organic light‐emitting diodes are urgently needed for next‐generation display and lighting applications. The discovery of thermally activated delayed fluorescence (TADF) has revealed a new class of promising candidates. After pairing the iminodibenzyl donor with the triazine acceptor via a phenylene linker, dihedral angle tuning is employed to regulate the difference between the energy levels of singlet and triplet excited states. Enhanced reverse intersystem crossing rates are observed in response to increased methylation at the phenylene linker. This behavior agrees with the density functional theory calculations. Photoluminescence quantum yields of up to 98% are achieved upon doping into a solid‐state matrix. When incorporated in devices, the maximum external quantum efficiency is 28.3% for the emitter with the most favorable trade‐off between singlet–triplet splitting and fluorescent oscillator strength. This result highlights the general applicability of dihedral angle tuning, a molecular design strategy that can be used to improve the performance of donor–acceptor type TADF emitters without significantly changing their emission spectra.
Radiation response characteristics of amorphous silicon arrays for megavoltage radiotherapy imaging (1992)

Signal measurements for a variety of pixelated a-Si:H imaging arrays irradiated by megavoltage beams are reported. Data are presented for 6-, 10-, and 15-MV beam energies for screens containing gadolinium-oxysulfide and calcium tungstate. These results are quantitative radiation signal sizes reported for such arrays. The initialization times of these arrays are reported. The performance of arrays of various sizes and pitches with respect to these measured values is compared. These results are part of an ongoing effort to develop flat-panel, real-time gamma and X-ray imagers.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Control of ion energy and angular distributions in dual-frequency capacitively coupled plasmas through power ratios and phase: Consequences on etch profiles (2015)

Anisotropic etching, enabled by energetic ion bombardment, is one of the primary roles of plasma–assisted materials processing for microelectronics fabrication. One challenge in plasma etching is being able to control the ion energy-angular distributions (IEADs) from the presheath to the surface of the wafer which is necessary for maintaining the critical dimension of features. Dual frequency capacitive coupled plasmas (DF-CCPs) potentially provide flexible control of IEADs, providing high selectivity while etching different materials and improved uniformity across the wafer. In this paper, the authors present a computational investigation of customizing and controlling IEADs in a DF-CCP resembling those industrially employed with both biases applied to the substrate holding the wafer. The authors found that the ratio of the low-frequency to high-frequency power can be used to control the plasma density, provide extra control for the angular width and energy of the IEADs, and to optimize etch profiles. If the phases between the low frequency and its higher harmonics are changed, the sheath dynamics are modulated, which in turn produces modulation in the ion energy distribution. With these trends, continuously varying the phases between the dual-frequencies can smooth the high frequency modulation in the time averaged IEADs. For validation, results from the simulation are compared with Langmuir probe measurements of ion saturation current densities in a DF-CCP.
A comparison on simulated, analytic, and measured impedance values for an inductive power transfer system (2020)

Studies on inductive power transfer (IPT) systems are most times either theoretical or experimental. In this paper, we want to bring theoretical models and experimental data together using the impedance based interface proposed in SAE J2954. This proposal characterizes the IPT system by impedances at both coil terminals. We show how the experimental data was retrieved at the interface and use it to validate an analytical model and a Simulink model described within this study. Such models can support the design and development process and therefore a comparison with reality is necessary.

Processing and Microstructural Characterization of B4C-AI Cermets (2008)

Reaction thermodynamics and wetting studies were employed to evaluate boron carbide-aluminum cermets. Wetting phenomenon and interfacial reactions are characterized using “macroscale” and “microscale” techniques. Macroscale evaluation involved alumium sessile drop studies on boron carbide substrates. Microscale evaluation involved the fabrication of actual cermet microstructures and their characterization through SEM, X-ray diffraction, metallography, and electron microprobe. Contact-angle measurements and interfacial-reaction products are reported.

Lithographically patterned nanowire electrodeposition (2008)

Abstract Lithographically Patterned Nanowire Electrodeposition (LPNE) is a new nanofabrication technique in which photolithography is used to define the position of electrodeposited nanowires on the surface of a dielectric such as glass or oxidized silicon. In LPNE, a resist‐covered nickel film with a thickness of beween 6 and 100 nm is photopatterned. After development of the resist, the exposed nickel is dissolved in nitric acid under conditions that produce an “undercut” at the resist edges. This undercut functions as a horizontal trench into which metals (e.g., Au, Pt, Pd) can be electrodeposited using the exposed nickel edge present within this trench. As this trench is filled during electrodeposition, a nanowire with a precisely defined height and width is formed along the entire perimeter of the photoresist. LPNE nanowires can have minimum dimensions of 6 nm (h) x 20 nm (w) and lengths of more than 1 cm. (© 2008 WILEY‐VCH Verlag GmbH &amp; Co. KGaA, Weinheim)

Targeting mitochondria in cancer therapy could provide a basis for the selective anti-cancer activity (2019)

To determine the target of the recently identified lead compound NSC130362 that is responsible for its selective anti-cancer efficacy and safety in normal cells, structure-activity relationship (SAR) studies were conducted. First, NSC13062 was validated as a starting compound for the described SAR studies in a variety of cell-based viability assays. Then, a small library of 1,4-naphthoquinines (1,4-NQs) and quinoline-5,8-diones was tested in cell viability assays using pancreatic cancer MIA PaCa-2 cells and normal human hepatocytes. The obtained data allowed us to select a set of both non-toxic compounds that preferentially induced apoptosis in cancer cells and toxic compounds that induced apoptosis in both cancer and normal cells. Anti-cancer activity of the selected non-toxic compounds was confirmed in viability assays using breast cancer HCC1187 cells. Consequently, the two sets of compounds were tested in multiple cell-based and in vitro activity assays to identify key factors responsible for the observed activity. Inhibition of the mitochondrial electron transfer chain (ETC) is a key distinguishing activity between the non-toxic and toxic compounds. Finally, we developed a mathematical model that was able to distinguish these two sets of compounds. The development of this model supports our conclusion that appropriate quantitative SAR (QSAR) models have the potential to be employed to develop anti-cancer compounds with improved potency while maintaining non-toxicity to normal cells.
Novel N‐Halamine Disinfectant Compounds (1991)

Abstract A new series of N ‐halamine compounds has been synthesized and tested for stability in aqueous solution and efficacy in inactivating several species of bacteria and algae. The compounds, which are N,N′ ‐dihalo‐4‐imidazolidinones, are inexpensive to synthesize and appear to have considerable potential as general‐purpose disinfectants. They have greater stability in the laboratory, as well as outdoors in direct sunlight, than do current commercial swimming pool biocides. They also are efficient at sterilizing hard surfaces (stainless steel) and could thus be useful for a variety of household and medical disinfection applications.

Cell-cycle-specific Cellular Responses to Sonoporation (2017)

Microbubble-mediated sonoporation has shown its great potential in facilitating intracellular uptake of gene/drugs and other therapeutic agents that are otherwise difficult to enter cells. However, the biophysical mechanisms underlying microbubble-cell interactions remain unclear. Particularly, it is still a major challenge to get a comprehensive understanding of the impact of cell cycle phase on the cellular responses simultaneously occurring in cell membrane and cytoskeleton induced by microbubble sonoporation. <b>Methods:</b> Here, efficient synchronizations were performed to arrest human cervical epithelial carcinoma (HeLa) cells in individual cycle phases. The, topography and stiffness of synchronized cells were examined using atomic force microscopy. The variations in cell membrane permeabilization and cytoskeleton arrangement induced by sonoporation were analyzed simultaneously by a real-time fluorescence imaging system. <b>Results:</b> The results showed that G1-phase cells typically had the largest height and elastic modulus, while S-phase cells were generally the flattest and softest ones. Consequently, the S-Phase was found to be the preferred cycle for instantaneous sonoporation treatment, due to the greatest enhancement of membrane permeability and the fastest cytoskeleton disassembly at the early stage after sonoporation. <b>Conclusion:</b> The current findings may benefit ongoing efforts aiming to pursue rational utilization of microbubble-mediated sonoporation in cell cycle-targeted gene/drug delivery for cancer therapy.
The DNA damage mark pH2AX differentiates the cytotoxic effects of small molecule HDAC inhibitors in ovarian cancer cells (2011)

High grade epithelial ovarian cancers are relatively sensitive to DNA damaging platinum-based chemotherapy, suggesting that the dependencies of ovarian tumors on DNA damage response pathways can be harnessed for therapeutic purposes. Our goal was to determine if the DNA damage mark gamma-H2AX phosphorylation (pH2AX) could be used to identify suitable cytotoxic histone deacetylase inhibitors (HDACi) for ovarian cancer treatment. Nineteen chemically diverse HDACi compounds were tested in 7 ovarian cancer cell lines. Fluorescent, biochemical and cell-based assays were performed to assess DNA damage by induction of pH2AX and to measure cell viability and apoptosis. The relationships between pH2AX and the cellular effects of cell viability and apoptosis were calculated. Selected HDACi were tested in combination with cisplatin and other DNA damaging agents to determine if the HDACi improved upon the effects of the DNA damaging agents. The HDACi compounds induced differing levels of pH2AX expression. High levels of pH2AX in HDACi-treated ovarian cancer cells were tightly associated with decreased cell viability and increased apoptosis. Consequently, a ketone-based HDACi was chosen and found to enhance the effects of cisplatin, even in ovarian cancer cells with extreme resistance to DNA damaging drugs. In conclusion, a fluorescent-based assay for pH2AX can be used to determine cellular responses to HDACi in vitro and may be a useful tool to identify potentially more effective HDACi for the treatment of ovarian cancer. In addition, these results lend support to the inclusion of ketone-derived HDACi compounds for future development.
Security Assessment of IP-based Networks: A Holistic Approach (1999)

This paper deals with network security assessment. We discuss currently available network security assessment tools and provide a categorization of their limitations. We revisit the methodology that the tools are based on, the flaw-hypothesis testing methodology. We then discuss the application of the methodology to network security assessment and discuss what is necessary to augment current network security assessment tools to make the testing methodology more holistic so confidence can be placed in the results reported by the tools. 1.

Steady-state and transient photocurrents in rubrene single crystal free-space dielectric transistors (2007)

We report results of photocurrent studies performed on rubrene single crystal transistors in the air-gap configuration under 405nm irradiation. The phototransistors show a strong photoresponse indicative of photoconduction. Under illumination, the phototransistors show an average threshold voltage shift of 22V and a maximum photosensistivity of 2.65×103. A small persistent photoconductivity effect is observed in the transistors tested under continuous illumination which is explained by delayed recombination aided by spatial separation of the photocarriers. Photocurrent transients measured by applying short pulses on the other hand show a complete recovery in the microsecond regime implying immediate recombination.
Altered Cardiolipin Metabolism is Associated with Cardiac Mitochondrial Dysfunction in Pulmonary Vascular Remodeled Perinatal Rat Pups (2021)

Abstract Background Pulmonary vascular remodeling (PVR) in utero results in the development of heart failure (HF). The alterations that occur in cardiac lipid and mitochondrial bioenergetics during the development of in utero PVR was unknown. Methods PVR was induced in pups in utero by exposure of pregnant dams to indomethacin and hypoxia. Cardiac lipids, echocardiographic function and cardiomyocyte mitochondrial function were subsequently examined. Results Perinatal rat pups with PVR exhibited elevated left and right cardiac ventricular internal dimensions and reduced ejection fraction and fractional shortening compared to controls. Cardiac myocytes from these pups exhibited increased glycolytic capacity and glycolytic reserve compared to controls. However, respiration with glucose as substrate was unaltered. Fatty acid oxidation and ATP-insensitive respiration were increased in isolated cardiac myocytes from these pups compared to controls indicating mitochondrial dysfunction. Although abundance of mitochondrial respiratory complexes were unaltered, increased trilinoleoyl-lysocardiolipin levels in these pups was observed. A compensatory increase in both cardiolipin (CL) and phosphatidylethanolamine (PE) content were observed due to increased synthesis of these phospholipids. Conclusion Alterations in cardiac cardiolipin and phospholipid metabolism in PVR rat pups is associated with the mitochondrial bioenergetic and cardiac functional defects observed in their hearts. Impact statement - Phospholipid metabolism was examined in pulmonary vascular remodeling in perinatal rat pups. - Pulmonary vascular remodeling was induced in utero by treating pregnant dams with hypoxia and indomethacin at 19-21 days of gestation. - The offspring exhibited altered pulmonary arterial remodeling with subsequent cardiac hypertrophy, ventricular dysfunction, cardiac myocyte mitochondrial dysfunction with altered fatty acid utilization. - In addition, the offspring exhibited elevated cardiolipin, lysocardiolipin and phosphatidylethanolamine content which may potentially contribute to the cardiac mitochondrial dysfunction.
Tailored Branched Polyolefins by Metallocene Catalysis (2007)

Abstract Metallocene/methylaluminoxane catalysts are able to design copolymers with tailored architectures. It is possible to copolymerize ethene with higher α ‐olefins and cyclic olefins. The terpolymer of ethene/1‐hexene/norbornene shows a better flexibility than the ethene/norbornene copolymer by a similar high transparency. The influence of the comonomer concentration on activity, molecular weight, and glass transition temperature is given as well as the comparison to 1‐hexene/norbornene and propene/norbornene copolymers. Hexene/norbornene copolymers were found to have a predominant alternating microstructure. magnified image
A Comparison of C-Store and Row-Store in a Common Framework (2006)

Recently, a ?column store? system called CStore has shown significant performance benefits by utilizing storage optimizations for a read-mostly query workload. The authors of the C-Store paper compared their optimized column store to a commercial row store RDBMS that is optimized for a mixture of reads and writes, which obscures the relative benefits of row and column stores. In this paper, we describe two storage optimizations for a row store architecture given a read-mostly query workload ? ?super tuples? and ?column abstraction.? We implement both our optimized row store and C-Store in a common framework in order to perform an ?apples-to-apples? comparison of the optimizations in isolation and combination. We also develop a detailed cost model for sequential scans tobreak down time spent into three categories ? disk I/O, iteration cost, and local tuple reconstruction cost. We conclude that, while the C-Store system offers tremendous performance benefits for scanning a small fraction of columns from a table, our optimized row store provides disk storage savings, reduced sequential scan times, and low additional CPU overheads while requiring only evolutionary changes to a standard row store.

Analysis of polarizing optical systems for digital optical computing with symmetric self electrooptic devices (1991)

This research developed imaging polarimetry to study the propagation of polarized light in polarization based optical interconnects such as the AT&amp;T digital optical computer, and adapted polarization aberration theory and polarization ray tracing, to understand new classes of problems arising in optical systems for digital optical computing. An imaging polarimeter was constructed and calibrated at UAH under this contract. The output is a Mueller matrix image, a spatial representation of the polarization properties across a wavefront, typically as a function of field of view or pupil coordinate. With the imaging polarimeter, one can simultaneously balance the transmitted polarization between the top and bottom, left and right sides of a wavefront as one rotates tilts, or otherwise adjusts the polarization components. Imaging polarimeter was demonstrated to be a useful alignment tool and was used to characterize many polarizing elements such as polarizing beam splitters, linear retarders, and liquid crystals.
RE-NOTE: An E-voting scheme based on ring signature and clash attack protection (2013)

In this paper, we will discuss an E-voting procedure by utilizing ring signature. The proposed scheme, RE-NOTE, is based on our previous work E-NOTE and has the benefit of reducing the risk of leaking voters' identities during the ballot distribution procedure. In addition, we will consider the “Clash Attack” which is a simple attack on the verification procedure during an election. Either authority or hackers may use the receipt to manipulate the voting results. We will show how our proposed scheme can mitigate such an attack. Our proposed scheme addresses issues related to both voter's and candidate's confidentiality and verification, and thus provides a framework for fair elections.
