Micro- and Nanostructured Materials for Active Devices and Molecular Electronics (2003)

Traditional single layer barrier coatings are not adequate in preventing degradation of the performance of organic molecular electronic and other active devices. Most advanced devices used in display technology now consist of micro and nanostructured small molecule, polymer and inorganic coatings with thin high reactive group 1A metals. This includes organic electronics such as organic light emitting devices (OLED). The lifetimes of these devices rapidly degrades when they are exposed to atmospheric oxygen and water vapor. Thin film photovoltaics and batteries are also susceptible to degradation by moisture and oxygen. Using in-line coating techniques we apply a composite nanostructured inorganic/polymer thin film barrier that restricts moisture and oxygen permeation to undetectable levels using conventional permeation test equipment. We describe permeation mechanisms for this encapsulation coating and flat panel display and other device applications. Permeation through the multilayer barrier coating is defect and pore limited and can be described by Knudsen diffusion involving a long and tortuous path. Device lifetime is also enhanced by the long lag times required to reach the steady state flux regime. Permeation rates in the range of 10-6 cc,g/m2/d have been achieved and OLED device lifetimes. The structure is robust, yet flexible. The resulting device performancemore » and lifetimes will also be described. The barrier film can be capped with a thin film of transparent conductive oxide yielding an engineered nanostructured device for next generation, rugged, lightweight or flexible displays. This enables, for the first time, thin film encapsulation of emissive organic displays.« less

Retargeting vector animation for small displays (2005)

We present a method that preserves the recognizability of key object interactions in a vector animation. The method allows an artist to author an animation once, and then output it to any display device. We specifically target mobile devices with small screen sizes. In order to adapt an animation, the author specifies an importance value for objects in the animation. The algorithm then identifies and categorizes the vector graphics objects that comprise the animation, leveraging the implicit relationship between extensible Markup Language (XML) and scalable vector graphics (SVG). Based on importance, the animation can then be automatically retargeted for any display using artistically motivated resizing and grouping algorithms that budget size and spatial detail for each object.
Novel Real-Time Library Search Driven Data Acquisition Strategy for Identification and Characterization of Metabolites (2022)

Structural characterization of novel metabolites in drug discovery or metabolomics is one of the most challenging tasks. Multilevel fragmentation (MS<sup><i>n</i></sup>) based approaches combined with various dissociation modes are frequently utilized for facilitating structure assignment of unknown compounds. As each of the MS precursors undergoes MS<sup><i>n</i></sup>, the instrument cycle time can limit the total number of precursors analyzed in a single LC run for complex samples. This necessitates splitting data acquisition into several analyses to target lower concentration analytes in successive experiments. Here we present a new LC/MS data acquisition strategy, termed Met-IQ, where the decision to perform an MS<sup><i>n</i></sup> acquisition is automatically made in real time based on the similarity between the experimental MS<sup>2</sup> spectrum and a spectrum in a reference spectral library for the known compounds of interest. If similarity to a spectrum in the library is found, the instrument performs a decision-dependent event, such as an MS<sup>3</sup> spectrum. Compared to an intensity-based, data-dependent MS<sup><i>n</i></sup> experiment, only a limited number of MS<sup>3</sup> are triggered using Met-IQ, increasing the overall MS<sup>2</sup> instrument sampling rate. We applied this strategy to an Amprenavir sample incubated with human liver microsomes. The number of MS<sup>2</sup> spectra increased 2-fold compared to a data dependent experiment where MS<sup>3</sup> was triggered for each precursor, resulting in identification of 14-34% more unique potential metabolites. Furthermore, the MS<sup>2</sup> fragments were selected to focus likely sources of useful structural information, specifically higher mass fragments to maximize acquisition of MS<sup>3</sup> data relevant for structure assignment. The described Met-IQ strategy is not limited to metabolism experiments and can be applied to analytical samples where the detection of unknown compounds structurally related to a known compound(s) is sought.
OODB Support for Real-Time Open-Architecture Controllers (1995)

Open-architecture machine tool controllers have been an important research subject in both academia and industry. They are hard realtime applications that require a built-in database management system to support concurrent data access and provide well-defined interfaces. These advanced applications often utilize object-oriented models to handle complex data types. Since there exists no agreed-upon real-time object model, we design a conceptual real-time object-oriented data model, called ROMPP (Real-time Object Model with Performance Polymorphism). It captures the key characteristics of realtime control applications, namely, timing constraints and performance polymorphism. It uses specialization dimensions to model timing specifications and letter class hierarchies to capture performance polymorphism. Based on the model, we develop a prototype controller on our open-architecture machine tool controller testbed. The controller has been successfully used for a 6-axis robotic table.

Unrest at Domuyo Volcano, Argentina, Detected by Geophysical and Geodetic Data and Morphometric Analysis (2019)

New volcanic unrest has been detected in the Domuyo Volcanic Center (DVC), to the east of the Andes Southern Volcanic Zone in Argentina. To better understand this activity, we investigated new seismic monitoring data, gravimetric and magnetic campaign data, and interferometric synthetic aperture radar (InSAR) deformation maps, and we derived an image of the magma plumbing system and the likely source of the unrest episode. Seismic events recorded during 2017–2018 nucleate beneath the southwestern flank of the DVC. Ground deformation maps derived from InSAR processing of Sentinel-1 data exhibit an inflation area exceeding 300 km2, from 2014 to at least March 2018, which can be explained by an inflating sill model located 7 km deep. The Bouguer anomaly reveals a negative density contrast of ~35 km wavelength, which is spatially coincident with the InSAR pattern. Our 3D density modeling suggests a body approximately 4–6 km deep with a density contrast of –550 kg/m3. Therefore, the geophysical and geodetic data allow identification of the plumbing system that is subject to inflation at these shallow crustal depths. We compared the presence and dimensions of the inferred doming area to the drainage patterns of the area, which support long-established incremental uplift according to morphometric analysis. Future studies will allow us to investigate further whether the new unrest is hydrothermal or magmatic in origin.
Ink-jet printing of carbon nanotube thin film transistors (2007)

Ink-jet printing is an important process for placing active electronics on plastic substrates. We demonstrate ink-jet printing as a viable method for large area fabrication of carbon nanotube (CNT) thin film transistors (TFTs). We investigate different routes for producing stable CNT solutions (“inks”). These consist of dispersion methods for CNT debundling and the use of different solvents, such as N-methyl-2-pyrrolidone. The resulting printable inks are dispensed by ink-jet onto electrode bearing silicon substrates. The source to drain electrode gap is bridged by percolating networks of CNTs. Despite the presence of metallic CNTs, our devices exhibit field effect behavior, with effective mobility of ∼0.07 cm2/V s and ON/OFF current ratio of up to 100. This result demonstrates the feasibility of ink-jet printing of nanostructured materials for TFT manufacture.
Narrow Band Red Emission Fluorophore with Reasonable Multiple Resonance Effect (2021)

Abstract Developing boron‐based emitters in red region with a narrow band spectrum is crucial and challenging for optoelectronic applications. Herein the authors report novel emitters with reasonable multiple resonance (MR) effect by utilizing a CC bond type connection instead of conventional CN bond. The designed emitters BP‐2DPA and DBP‐4DPA exhibit narrowband pure red emissions with photoluminescence (PL) maxima of 599, 605 nm with a full width half maximum (FWHM) of 34 nm and high PL quantum yield of 91.3, 96.4%, respectively. Moreover, compared to reported MR emitters, the synthesis of BP‐2DPA and DBP‐4DPA has resulted in a high yield near to 40% with ease to scale in grams. The designed rigid moieties show reasonable MR effect with atomically highest occupied molecular orbital and lowest unoccupied molecular orbital separations. The fabricated organic light‐emitting diodes based on BP‐2DPA and DBP‐4DPA possessed an external quantum efficiency of 11.3% and 15.1%, pure red emission with electroluminescence maxima at 605 and 617 nm, a narrow FWHM of 42 and 44 nm respectively. The corresponding CIE coordinates are well approaching near to red color NTSC requirements. This is the first work reported with this strategy for achieving narrow emission spectrum for pure red color emitters.

Characterization of Solids Collected from H-Area Injection Wells and Injection Tank Chemistry from both F- and H-Area Water Treatment Units (WTUs) (1999)

This study suggests that a strong poitential exists for both chemical and biological fouling of the injection wells at the F- and H Area remediation systems. To further the potential, an evaluation of WTU process chemistry, characterization of the natural groundwater geochemistry, and analysis of microbiological activity should be performed. This report summarizes the results.
[How to detect the complications of the cirrhosis?]. (2007)

The occurrence of complications marks a turn in the natural history of cirrhosis. The early management, the etiologic treatment of the subjacent disease, the methodological detection of hepatocarcinoma, the prophylaxis of digestive bleeding linked to portal hypertension, the control of ascite and prevention of hepato-renal syndrome allow to improve the prognosis of these patients. Moreover, bacterial infection represents one of the principal factor facilitating the occurrence of another complication. This is why any complication should be considered as secondary to bacterial infection until the refutation.
A universal concept for area‐selective assembly of metal oxide core‐shell nanoparticles, nanorods, and organic molecules via amide coupling reactions (2022)

Abstract The deposition of nanomaterials (NMs) on substrate is a pertinent for a variety of applications in nanometer‐sized electronics, mechanics, or catalysis. This paper establishes a universal and simple approach for assembly of functionalized metal oxide core nanoparticles (NPs) and nanorods (NRs) on a substrate with uniformity, area‐selectivity, and full order control. Particularly, the aluminium oxide (AlO x ) NPs, titanium dioxide (TiO 2 ) NRs, and TiO 2 NPs functionalized by self‐assembled monolayer (SAM) molecules are deposited on substrate alternatively layer‐by‐layer. This assembling is performed in solution on the pre‐patterned surface with SAM molecules via amide coupling reactions in order to achieve the reaction‐orthogonality. Moreover, this stacking of inorganic NPs/NRs in a terminated implementation is progressed into latter layer of TiO 2 NPs functionalized by 1‐aminopyrene molecules representing an example of hybrid organic‐inorganic formation with fluorescence emission. The deposited layers are characterized by scanning electron microscopy (SEM), atomic force microscopy (AFM), and total internal reflection fluorescence microscope (TIRFM). The significant versatility of stacked metal oxide core‐shell NPs/NRs via based‐solution method represents excellent and efficient applicability in manufacture of hybrid organic–inorganic nanostructure.
An Interleaved Boost and Dual Active Bridge Based Three Port Microinverter (2020)

In this paper, a new three port converter is proposed that interfaces two DC voltage sources of different magnitude and an output AC port. The proposed converter is primarily based on dual active bridge topology where, the secondary bridge is composed of four quadrant bidirectional switches, realized by placing regular MOSFETs in back to back fashion. In this configuration, the secondary side can be directly connected to an AC port. The primary bridge can also be used as an interleaved bidirectional boost converter by connecting two inductors across the transformer primary, which forms an additional input DC port. The power flow between the DC ports to the AC port is based on dual phase shift modulation where a phase shift is introduced between the two legs of the primary bridge switches and another phase shift between the primary and secondary bridge. This enables the standard sine pulse width modulation to be used for synthesizing AC output. A 200W prototype was built to experimentally verify the theoretical analysis of the proposed converter.
THE DESIGN OF VORTEX INDUCED VIBRATION FLUID KINETIC ENERGY HARVESTERS (2012)

Due to the rapid development in the field of microsystem technology during the last decade, micro energy sources become the bottleneck in most of the applications. In order to extend the usable range of environment energy sources, a fluid kinetic energy harvester is proposed. Compared to a hydro-turbine structure it is more robust and has a better performance at smaller scale. The related theoretical background is introduced as well as different simulations in order to optimize the performance are carried out. The demonstrator design based on those simulation results is tested and evaluated. First experimental results are presented and compared with simulation results.
Efficiency Assessment of Parallel Workloads on Virtualized Resources (2011)

In cloud computing, virtual containers on physical resources are provisioned to requesting users. Resource providers may pack as many containers as possible onto each of their physical machines, or may pack specific types and quantities of virtual containers based on user or system QoS objectives. Such elastic provisioning schemes for resource sharing may present major challenges to scientific parallel applications that require task synchronization during execution. Such elastic schemes may also inadvertently lower utilization of computing resources. In this paper, we describe the elasticity constraint effect and ripple effect that cause a negative impact to application response time and system utilization. We quantify the impact using real workload traces through simulation. Then, we demonstrate that some resource scheduling techniques can be effective in mitigating the impacts. We find that a tradeoff is needed among the elasticity of virtual containers, the complexity of scheduling algorithms, and the response time of applications.
Rhenium-Catalyzed Highly Efficient Oxidations of Tertiary Nitrogen Compounds to N-Oxides Using Sodium Percarbonate as Oxygen Source (2006)

Design of microwave MCM-D CPW quadrature couplers and power dividers in X-, Ku-, and Ka-band (2000)

The successful design and measurement of high-performance coplanar waveguide (CPW) quadrature hybrid couplers integrated in MCM-D at Ku and Ka-band and a Wilkinson power divider at X-band is discussed. We have investigated the feasibility of integrating 3-dB quadrature couplers in our MCM-D technology. Quadrature couplers based on two edge-coupled lines are not practical, as the required line-dimensions are too small. As an alternative, couplers using re-entrant sections and CPW Lange couplers have been realized. For the Lange coupler, we have obtained in the 10.5-14.5 GHz band: a return loss and isolation better than 20 dB, an amplitude balance below 0.13 dB and a phase balance of (90 +/- 1) deg. For the coupler using re-entrant sections, we have obtained in the 20-30 GHz band: a return loss better than 17 dB, isolation better than 20 dB, an amplitude balance below 0.25 dB and a phase-balance of(90 +/- 2.5) deg. A trade-off between these two design-approaches for integration in MCM-D is given. A first Wilkinson power-divider at X-band has also been designed and measured to verify the accuracy of the in-house models. Excellent agreement has been found up to 50 GHz.
Feasibility of 2nd generation STS retinal prosthesis in dogs (2013)

We developed a 2(nd) generation suprachoroidal transretinal stimulation (STS) system with a 49 channel electrode array and implanted in 2 dogs. One month after surgery, all electrodes were functioning and the ocular fundus was normal in both dogs. The results indicate the 2(nd) generation STS retinal prosthesis is feasible and can be considered for clinical use.
■ REVIEW : Gene Expression in Nerve Regeneration (1997)

Injury of peripheral nerve in mammals leads to a complex but stereotypical pattern of histological events that comprise a highly reproducible sequence of degenerative reactions (Wallerian degeneration) succeeded by regenerative responses. These reactions are based on a corresponding sequence of cellular and mo lecular interactions that, in turn, reflect the differential expression of specific genes with functions in nerve degeneration and repair. We report on more than 60 genes and their products that show a specific pattern of regulation following peripheral nerve lesion. The group of regulated genes encoding, e.g., transcription factors, growth factors and their receptors, cytokines, neuropeptides, myelin proteins and lipid carriers, and cytoskeletal proteins as well as extracellular matrix and cell adhesion molecules. We describe and compare the distinct time-courses and cellular origin of expression and further discuss established or putative mo lecular interrelationships and functions with respect to the contribution of these genes/gene products to the molecular regeneration program of the PNS.

Minimally invasive biomarker confirms glial activation present in Alzheimer's disease: a preliminary study (2011)

We applied (13)C magnetic resonance spectroscopy (MRS), a nonradioactive, noninvasive brain imaging technique, to quantify the oxidation of [1-(13)C] acetate in a conventional clinical magnetic resonance imaging (MRI) scanner in five consecutive elderly subjects at various clinical stages of Alzheimer's disease (AD) progression. [1-(13)C] acetate entered the brain and was metabolized to [5-(13)C] glutamate and glutamine, as well as [1-(13)C] glutamate and glutamine, and the final glial oxidation product, (13)C bicarbonate, at a linear rate. Calculation of the initial slope was similar in a single subject, examined twice, 1 month apart (test-re-test 8%). Mean rate of cerebral bicarbonate production in this elderly group was 0.040 ± 0.01 (n = 5). Assuming that the rate of conversion of acetate to bicarbonate is a reflection of glial metabolic rate and that glial metabolic rate is a surrogate marker for 'neuroinflammation', our preliminary results suggest that [1-(13)C] MRS may provide biomarkers for diseases, believed to involve microglia and other cells of the astrocyte series. Among these is AD, for which novel drugs which ameliorate the damaging effects of neuroinflammation before symptoms of dementia appear, are in advanced development. The value of (13)C MRS as an early, noninvasive biomarker may lie in the conduct of cost-effective clinical trials.
AROM: An Adaptive Resource Optimization Model for Mobile IoT Edge (2020)

Crowdsourced approach using mobile phones towards rescue and relief operations in post-disaster situations is becoming popular. The mobile phones play a critical role in estimation, evacuation and relief operations as they can be used for sensing and transmitting information such as location, elevation, acceleration, images and other user generated messages, but the mobile IoT edge devices are often resource constrained by battery and network. In this paper we present AROM, an Adaptive Resource Optimization Model for optimizing mobile sensing and communication systems, by considering network and battery constraints. AROM works by adaptively computing a resource criticality score and controlling sensing mechanisms and throttling and prioritizing network communications based on the score. We also present the details of performance tests done to validate our model and the analysis of results. We have implemented this architecture in our Amrita-Kripa disaster relief application which was deployed during 2018 and 2019 Kerala floods for rescues and relief activities.
