Electrocatalytic Reduction of CO<sub>2</sub> to Formate by an Iron Schiff Base Complex (2018)

The synthesis, structural characterization, and reactivity of an iron(III) chloride compound of 6,6'-di(3,5-di-tert-butyl-2-hydroxybenzene)-2,2'-bipyridine (Fe(<sup>tbu</sup>dhbpy)Cl), under electrochemically reducing conditions is reported. In the presence of carbon dioxide (CO<sub>2</sub>) under anhydrous conditions in N,N-dimethylformamide (DMF), this complex mediates the 2e<sup>-</sup> reductive disproportionation of two equivalents of CO<sub>2</sub> to carbon monoxide (CO) and carbonate (CO<sub>3</sub><sup>2-</sup>). Upon addition of phenol (PhOH) as a proton source under CO<sub>2</sub> saturation, catalytic current is observed; product analysis from controlled potential electrolysis experiments shows the majority product is formate (68 ± 4% Faradaic efficiency), with H<sub>2</sub> as a minor product (30 ± 10% Faradaic efficiency) and minimal CO (1.1 ± 0.3% Faradaic efficiency). On the basis of data obtained from cyclic voltammetry and infrared spectroelectrochemistry (IR-SEC), the release of CO from intermediate Fe carbonyl species is extremely slow and undergoes competitive degradation, limiting the activity and lifetime of this catalyst. Mechanistic studies also indicate the phenolate moieties coordinated to Fe are sensitive to protonation in the reduced state, suggesting the possibility of cooperative pendent proton interactions being involved in CO<sub>2</sub> reduction.
GeoSOT-Based Spatiotemporal Index of Massive Trajectory Data (2019)

With the rapid development of global positioning technologies and the pervasiveness of intelligent mobile terminals, trajectory data have shown a sharp growth trend both in terms of data volume and coverage. In recent years, increasing numbers of LBS (location based service) applications have provided us with trajectory data services such as traffic flow statistics and user behavior pattern analyses. However, the storage and query efficiency of massive trajectory data are increasingly creating a bottleneck for these applications, especially for large-scale spatiotemporal query scenarios. To solve this problem, we propose a new spatiotemporal indexing method to improve the query efficiency of massive trajectory data. First, the method extends the GeoSOT spatial partitioning scheme to the time dimension and forms a global space–time subdivision scheme. Second, a novel multilevel spatiotemporal grid index, called the GeoSOT ST-index, was constructed to organize trajectory data hierarchically. Finally, a spatiotemporal range query processing method is proposed based on the index. We implement and evaluate the index in MongoDB. By comparing the range query efficiency and scalability of our index with those of the other two space–time composite indexes, we found that our approach improves query efficiency levels by approximately 40% and has better scalability under different data volumes.
Jointly Deep Multi-View Learning for Clustering Analysis (2018)

In this paper, we propose a novel Joint framework for Deep Multi-view Clustering (DMJC), where multiple deep embedded features, multi-view fusion mechanism and clustering assignments can be learned simultaneously. Our key idea is that the joint learning strategy can sufficiently exploit clustering-friendly multi-view features and useful multi-view complementary information to improve the clustering performance. How to realize the multi-view fusion in such a joint framework is the primary challenge. To do so, we design two ingenious variants of deep multi-view joint clustering models under the proposed framework, where multi-view fusion is implemented by two different schemes. The first model, called DMJC-S, performs multi-view fusion in an implicit way via a novel multi-view soft assignment distribution. The second model, termed DMJC-T, defines a novel multi-view auxiliary target distribution to conduct the multi-view fusion explicitly. Both DMJC-S and DMJC-T are optimized under a KL divergence like clustering objective. Experiments on six challenging image datasets demonstrate the superiority of both DMJC-S and DMJC-T over single/multi-view baselines and the state-of-the-art multiview clustering methods, which proves the effectiveness of the proposed DMJC framework. To our best knowledge, this is the first work to model the multi-view clustering in a deep joint framework, which will provide a meaningful thinking in unsupervised multi-view learning.
High power-durable and low loss single-crystalline Al/Ti electrodes for RF SAW devices (2002)

In order to improve the power-durability of the electrodes in a RF SAW device, single-crystalline Al/Ti films were successfully grown on 64/spl deg/Y-X LiNbO/sub 3/ substrates by the conventional electron-beam vapor deposition technique. It is clear that the insertion loss of RF SAW filters with the single-crystalline electrodes was lower by about 0.1 dB compared with those with polycrystalline Al electrodes. Moreover, the time to failure for the single-crystalline electrodes became approximately 700 times longer than that for Al-Cu alloy electrodes which have been widely used in high-power RF SAW devices.

DESARROLLO Y CARACTERIZACIÓN DE MICROPARTÍCULAS DE ÁCIDO FÓLICO FORMADAS POR SECADO POR ASPERSIÓN, UTILIZANDO GOMA ARÁBIGA Y MALTODEXTRINA COMO MATERIALES DE PARED (2009)

El acido folico es una vitamina esencial, que participa en la biosintesis de aminoacidos esenciales y en algunos procesos asociados al ADN. Es una vitamina con limitaciones en su estabilidad frente a factores como la luz, pH y oxigeno. Por esta razon se hace necesario desarrollar estrategias que permitan su estabilizacion sin afectar su actividad biologica. Asi pues, se propone la obtencion de microparticulas utilizando mezclas de goma arabiga y maltodextrina, con el metodo de secado por aspersion, que presenten caracteristicas adecuadas para actuar como un reservorio del acido folico con potencialidades para su estabilizacion. En este estudio se obtienen microparticulas de acido folico utilizando cuatro mezclas diferentes de goma arabiga y maltodextrina, caracterizadas mediante los siguientes parametros: distribucion de tamano de particula, porcentaje de humedad, morfologia, eficiencia de encapsulacion y perfil de disolucion. Los resultados de la caracterizacion muestran diferentes aspectos: la morfologia de las microparticulas obtenidas por este metodo varia con la relacion goma arabiga- maltodextrina, la eficiencia de encapsulacion es elevada para los cuatro tipos de microparticulas estudiadas, la distribucion de tamano de particula no cambia con la relacion de los materiales de la pared y los perfiles de disolucion muestran un porcentaje de disolucion limitado, siendo el mejor el que corresponde a microparticulas con la relacion goma arabiga- maltodextrina 70-30. La goma arabiga es efectiva para el atrapamiento del acido folico y cuando se mezcla con maltodextrina se mejoran las caracteristicas de morfologia, eficiencia y disolucion de las microparticulas, lo cual sugiere que existe una mezcla optima de los dos materiales de pared que optimizan las caracteristicas de las microparticulas.
A combined compression molding, heating, and leaching process for fabrication of micro-porous poly(ε-caprolactone) scaffolds (2018)

Biomaterial scaffolds have been increasingly used for tissue engineering applications as well as three dimensional (3D) cell culture models. Herein, we report a simple procedure combining compression molding, heating, and leaching methods for the fabrication of 3D micro-porous poly(ε-caprolactone) (PCL) biomaterial scaffolds. In this procedure, PCL micro particles are mixed with NaCl of defined sizes and compression molded, followed by heating and subsequent leaching of NaCl particles. This technique eliminates the gas foaming method, which is commonly used in the fabrication of PCL scaffolds. Process and scaffold parameters (i.e., heating time, NaCl concentration, and NaCl particle size) were varied and analyzed to determine their impact on the overall scaffold structural and mechanical properties. An increase in NaCl particle size led to an increase in pore area but did not significantly impact the mechanical properties of the scaffolds. Additionally, NaCl concentration did not show a significant effect on pore area, but considerably impacted the mechanical properties, water absorption capacity and porosity of the scaffolds. Variations in the heating time did not have an effect in the pore area, porosity, water absorption capacity or mechanical properties of the scaffolds. We also demonstrated the ability of these scaffolds to support the proliferation of breast cancer cells. Overall, these results elucidated structure-property relationships in the fabricated micro-porous PCL scaffolds. Further, this procedure could be potentially scaled up for the fabrication of micro-porous PCL scaffolds.
Characterization of housekeeping genes in zebrafish: male-female differences and effects of tissue type, developmental stage and chemical treatment (2008)

This study provides data that can be expected to aid zebrafish researchers in their initial choice of housekeeping genes for future studies, but underlines the importance of further validating housekeeping genes for each new experimental paradigm and fish species.
Fabrication of Histidine-Tagged Fusion Protein Arrays for Surface Plasmon Resonance Imaging Studies of Protein−Protein and Protein−DNA Interactions (2003)

The creation and characterization of histidine-tagged fusion protein arrays using nitrilotriacetic acid (NTA) capture probes on gold thin films for the study of protein-protein and protein-DNA interactions is described. Self-assembled monolayers of 11-mercaptoundecylamine were reacted with the heterobifunctional linker N-succinimidyl S-acetylthiopropionate (SATP) to create reactive sulfhydryl-terminated surfaces. NTA capture agents were immobilized by reacting maleimide-NTA molecules with the sulfhydryl surface. The SATP and NTA attachment chemistry was confirmed with Fourier transform infrared reflection absorption spectroscopy. Oriented protein arrays were fabricated using a two-step process: (i) patterned NTA monolayers were first formed through a single serpentine poly(dimethylsiloxane) microchannel; (ii) a second set of parallel microchannels was then used to immobilize multiple His-tagged proteins onto this pattern at discrete locations. SPR imaging measurements were employed to characterize the immobilization and specificity of His-tagged fusion proteins to the NTA surface. SPR imaging measurements were also used with the His-tagged fusion protein arrays to study multiple antibody-antigen binding interactions and to monitor the sequence-specific interaction of double-stranded DNA with TATA box-binding protein. In addition, His-tagged fusion protein arrays created on gold surfaces were also used to monitor antibody binding with fluorescence microscopy in a sandwich assay format.

Combination treatment with decitabine and ionizing radiation enhances tumor cells susceptibility of T cells (2016)

Decitabine has been found to have anti-metabolic and anti-tumor activities in various tumor cells. Recently, the use of decitabine in combination with other conventional therapies reportedly resulted in improved anti-tumor activity against various tumors. Ionizing radiation (IR) is widely used as a cancer treatment. Decitabine and IR improve immunogenicity and susceptibility of tumor cells to immune cells by up-regulating the expression of various molecules such as major histocompatibility complex (MHC) class I; natural-killer group 2, member D (NKG2D) ligands; and co-stimulatory molecules. However, the effects of combining decitabine and IR therapies are largely unknown. Our results indicate that decitabine or IR treatment upregulates MHC class I, along with various co-stimulatory molecules in target tumor cells. Furthermore, decitabine and IR combination treatment further upregulates MHC class I, along with the co-stimulatory molecules, when compared to the effect of each treatment alone. Importantly, decitabine treatment further enhanced T cell-mediated cytotoxicity and release of IFN- γ against target tumor cells which is induced by IR. Interestingly, decitabine did not affect NKG2D ligand expression or NK cell-mediated cytotoxicity in target tumor cells. These observations suggest that decitabine may be used as a useful immunomodulator to sensitize tumor cells in combination with other tumor therapies.

The circadian clock components BMAL1 and REV-ERBα regulate flavivirus replication (2019)

The circadian clock regulates immune responses to microbes and affects pathogen replication, but the underlying molecular mechanisms are not well understood. Here we demonstrate that the circadian components BMAL1 and REV-ERBα influence several steps in the hepatitis C virus (HCV) life cycle, including particle entry into hepatocytes and RNA genome replication. Genetic knock out of Bmal1 and over-expression or activation of REV-ERB with synthetic agonists inhibits the replication of HCV and the related flaviruses dengue and Zika via perturbation of lipid signaling pathways. This study highlights a role for the circadian clock component REV-ERBα in regulating flavivirus replication.
Spectrum sensing in cognitive radio networks: requirements, challenges and design trade-offs (2008)

Opportunistic unlicensed access to the (temporarily) unused frequency bands across the licensed radio spectrum is currently being investigated as a means to increase the efficiency of spectrum usage. Such opportunistic access calls for implementation of safeguards so that ongoing licensed operations are not compromised. Among different candidates, sensing-based access, where the unlicensed users transmit if they sense the licensed band to be free, is particularly appealing due to its low deployment cost and its compatibility with the legacy licensed systems. The ability to reliably and autonomously identify unused frequency bands is envisaged as one of the main functionalities of cognitive radios. In this article we provide an overview of the regulatory requirements and major challenges associated with the practical implementation of spectrum sensing functionality in cognitive radio systems. Furthermore, we outline different design trade-offs that have to be made in order to enhance various aspects of the system's performance.
Interactive Layout Mechanisms for Image Database Retrieval (1996)

In this paper we present a user interface, CANDID Camera, for image retrieval using query-by-example technology. Included in the interface are several new layout algorithms based on multidimensional scaling techniques that visually display global and local relationships between images within a large image database. We use the CANDID project algorithms to create signatures of the images, and then measure the dissimilarity between the signatures. The layout algorithms are of two types. The first are those that project the all-pairs dissimilarities to two dimensions, presenting a many-to-many relationship for a global view of the entire database. The second are those that relate a query image to a small set of matched images for a one-to-many relationship that provides a local inspection of the image relationships. Both types are based on well-known multidimensional scaling techniques that have been modified and used together for efficiency and effectiveness. They include nonlinear projection and classical projection. The global maps are hybrid algorithms using classical projection together with nonlinear projection. We have developed several one-to-many layouts based on a radial layout, also using modified nonlinear and classical projection.
Fiber Bragg grating vacuum sensors (2005)

This letter demonstrates functional enhancements of fiber Bragg grating sensors powered by in-fiber light. High-power laser light transmitted in double-clad optical fiber was extracted from the fiber core to heat an on-fiber metal coating. When the power-laser is turned off, the fiber Bragg grating is used as a passive component for temperature sensing. When the laser is turned on, the thermal response of the optically heated grating was used to monitor ambient air pressure. The sensitivity and dynamic range of optically powered fiber sensors can be actively adjusted by in-fiber light to measure vacuum pressures over four orders of magnitude.
Cell Delivery with Fixed Amniotic Membrane Reconstructs Corneal Epithelium in Rabbits with Limbal Stem Cell Deficiency (2010)

These findings demonstrate that the BMFD with fixed AM served well as a cell delivery system for the ocular surface. The delivered limbal epithelial cells promoted corneal re-epithelialization and prevented corneas from conjunctivalization and neovascularization in rabbits with experimental LSCD.
Molecular Interactions between the Specialist Herbivore<i>Manduca sexta</i> (Lepidoptera, Sphingidae) and Its Natural Host <i>Nicotiana attenuata</i>. III. Fatty Acid-Amino Acid Conjugates in Herbivore Oral Secretions Are Necessary and Sufficient for Herbivore-Specific Plant Responses (2001)

Feeding by the tobacco specialist Manduca sexta (Lepidoptera, Sphingidae) and application of larval oral secretions and regurgitant (R) to mechanical wounds are known to elicit: (a) a systemic release of mono- and sesquiterpenes, (b) a jasmonate burst, and (c) R-specific changes in transcript accumulation of putatively growth- and defense-related mRNAs in Nicotiana attenuata Torr. ex Wats. We identified several fatty acid-amino acid conjugates (FACs) in the R of M. sexta and the closely related species Manduca quinquemaculata which, when synthesized and applied to mechanical wounds at concentrations comparable with those found in R, elicited all three R-specific responses. Ion-exchange treatment of R, which removed all detectable FACs and free fatty acids (FAs), also removed all detectable activity. The biological activity of ion-exchanged R could be completely restored by the addition of synthetic FACs at R-equivalent concentrations, whereas the addition of FAs did not restore the biological activity of R. We conclude that the biological activity of R is not related to the supply of FAs to the octadecanoid cascade for endogenous jasmonate biosynthesis, but that FACs elicit the herbivore-specific responses by another mechanism and that the insect-produced modification of plant-derived FAs is necessary for the plant's recognition of this specialized herbivore.

F901318 demonstrated potent in vitro activity against Scedosporium species and L. prolificans . This activity was maintained against isolates that had significantly reduced susceptibility to the other antifungals. Further studies are warranted to evaluate the in vivo efficacy of F901318 against Scedosporium species and L. prolificans .
640 × 512 17 μm microbolometer FPA and sensor development (2007)

RVS has made a significant breakthrough in the development of a 640 x 512 uncooled array with a unit cell size of 17 μm x 17 μm, and performance approaching that of the 25μm arrays. The successful development of this array is the first step in achieving mega-pixel formats. This FPA is designed to ultimately achieve performance of (<50mK, f/1, 30 Hz) with an 8 msec time constant. The SB-400 is a highly productized ROIC and is designed to achieve very good sensitivity (low NETD and low spatial noise) and good dynamic range. The improved performance is through bolometer structure improvements and an innovative ROIC design. It also has a simple and flexible electrical interface which allows external electronics to be small, lightweight, low-cost, and low-power. Almost all adjustments can be made through the serial interface; hence there is no need for external adjustable (DAC) circuitry. The improved power supply rejection helps maintain highly stable detector and strip resistor bias voltages which helps reduce spatial noise and image artifacts. The combination of reduced FPA pixel size and improved effective thermal sensitivity enhances weapon sight performance by providing smaller, lighter-weight sights via reduced optics size or increased range via enhanced pixel resolution without increasing mass or increased range via improved NETD (lower f/#) without increasing mass. We will also provide an update on the enhanced performance and yield producibility of our NVESD ManTech 640 x 480 25μm arrays. We will also show the improvement in our uncooled common architecture electronics in terms of reduced power and size for helmet and rifle mounted sensors and a variety of missile applications.
