Performance comparison of guided-wave architectures for space-division photonic switching (2004)

The paper presents and compares various unicast nonblocking architectures to be used into space-domain photonic switching networks. All the analyzed architectures have been evaluated and compared considering a possible physical implementation based on guided-wave structures realized with integrated optics technology. Some properties including number of switching elements required, blocking performance, number of waveguide crossovers, system attenuation, and signal-to-noise ratio are evaluated and analyzed. The main purpose of this work is to review the state-of-the-art of optical guided-wave space-switching architectures and to provide a relevant set of technical elements useful in the selection of architectures to be used in all-optical cross-connect implementation.

The prevalence of abnormalities on brain MRI for PWE in resource-limited settings is high as a result of a diffuse range of etiologies, most commonly mesial temporal sclerosis. Drug-resistant epilepsy accounted for 12% of the referral population in a conservative estimation.
High Throughput Satellite System with Q/V-band gateways and its integration with terrestrial broadband communication networks (2014)

Satellite broadband systems will play a key role in reducing the Digital Divide by complementing terrestrial networks in the delivery of superfast broadband in remote and rural areas. We present the system architecture, sizing and performance assessment of a next generation High Throuhgput Satellite system with Q/V-band gateways targeting the 2020 timeframe. In addition, we present a novel optimisation framework for the design of the backbone network interconnecting the satellite gateways with national PoPs in the serviced countries, which takes into account the impact in costs an payload constraints.
Review of Control Methods in Grid-Connected PV and Energy Storage System (2021)

This paper presents a comprehensive review of the present control techniques used in integrated grid-tied PV and Energy Storage (ES) system. With the recent exponential increase in PV deployment, coupled with continuing cost decline of battery technology, integration of ES to the grid has become prevailing, and in many places is a mandate. In this paper, we will provide an overall review of the current state-of-art of the PV smoothing techniques, microgrid (MG) control with conventional converters and novel multiport converters in terms of battery energy management and different grid operation modes. In addition, a summary of these control methods with merits, demerits, and future research directions is presented. Finally, emerging grid-forming control methods for future grid comprising of numerous distributed energy resources are also discussed.
Extracellular vesicle-mediated cellular crosstalk in lung repair, remodelling and regeneration (2022)

The unperturbed lung is highly quiescent, with a remarkably low level of cell turnover. However, once damaged, the lung shows an extensive regenerative capacity, with resident progenitor cell populations re-entering the cell cycle and differentiating to promote repair. This quick and dramatic repair response requires interactions among more than 40 different cell lineages in the lung, and defects in any of these processes can lead to various lung pathologies. Understanding the mechanisms of interaction in lung injury, repair and regeneration thus has considerable practical and therapeutic implications. Moreover, therapeutic strategies for replacing lung progenitor cells and their progeny through cell therapy have gained increasing attention. In the last decade, extracellular vesicles (EVs), including exosomes, have been recognised as paracrine mediators through the transfer of biological cargo. Recent work has revealed that EVs are involved in lung homeostasis and diseases. In addition, EVs derived from specific cells or tissues have proven to be a promising cell-free modality for the treatment of lung diseases. This review highlights the EV-mediated cellular crosstalk that regulates lung homeostasis and discusses the potential of EV therapeutics for lung regenerative medicine.
Hardness and Wear Properties of Ti-Mo-C-N Film (2015)

The hardness and wear properties of Ti-Mo-C-N films were investigated by nanoindentation and ball-on-disc measurements, respectively. Ti-Mo-C-N films were deposited onto a stainless steel substrate by a reactive RF magnetron sputtering in the mixture of argon (7.5 ccm) and nitrogen (0-6.0 ccm) gases using Ti25Mo25C50 target. Ti-Mo-C film deposited without nitrogen gas flow showed a hardness of 34.8 GPa. The hardness drastically decreased with increasing nitrogen gas flow rate (fN2) and reached to a minimum hardness of 16.4 GPa at fN2=2.0 ccm. Contrarily, at over fN2=3.0 ccm, the hardness drastically increased with increasing fN2 and reached a maximal value of 32 GPa, and then slightly decreased again with further increase of fN2. It was found by TEM observation that the drastic decrease in hardness is caused by the formation of nanocrystalline microstructure, while the increase in hardness is due to the microstructural change from nanocrystalline to columner structure. The friction coefficient decreased with increasing fN2 and the film deposited at fN2=5.0 ccm showed a minimum value of 0.27. The simple oxidation test in air indicated that lubricious MoO3 is easy to be formed in the film deposited at a high fN2, which should cause the reduction of friction coefficient.

A 3D nanofibrous Pt–TiO<sub>2</sub> capillary photocatalytic system is developed to perform photocatalytic H<sub>2</sub> production outside of the electrolyte body. Enhanced reaction kinetics and a higher yield of H<sub>2</sub> are obtained in the capillary setup compared to the conventional in-electrolyte setup.
Influence of voltage on electrode mass change of AgNi contacts for electromagnetic contactors: relativity of contact resistance and arc mode (2012)

The experiments at several source voltages were carried out to clarify the influence of the voltage on various characteristics, arc duration, contact resistance, arc energy, and electrode mass change. The source voltages are changed from 100V to 160V, load current is set to 5A constant, and an electromagnetic contactor is operated continuously up to 100,000 times. The experiments were carried out under the three Modes. In Mode-1, the both arc was generated when contactor was make and break. In Mode-2, when contactor was opened, only break arc was generated. And, when contactor was closed, only make arc was occurred in Mode-3. As a result, the relation between the arc Mode and contact resistance was clarified. The contact resistance of Mode-3 was lowest. In addition, the source voltage was not influenced to contact resistance. The anode arc was expected to be generated in Mode-3.

An O-band coherent optical receiver (CORX) is integrated in a 45-nm mono-lithic CMOS SOI process. The CORX operates to 80 Gbps with FEC-acceptable BER at 1.2 pJ/bit energy efficiency. To our knowledge, this is the first monolithically-integrated Silicon CMOS CORX.
VisBiz: A Business Process Visualization Case Study (2005)

Business process management involves many parameters and relationships and is modeled as complex business process workflows. A common way to analyze the process data is by using flowcharts. Visual analysis of a largescale chart, however, is too complex. In this case study, we employ a novel visualization technique, called VisBiz. VisBiz reduces data complexity by automatically analyzing operational data and abstracting the most critical parameters that influence business process. The basic idea is to select the most relevant parameters and layout them on a triple-attributes circular graph based on their relationships and user domain knowledge. VizBiz transforms the attributes to nodes and the process flows to lines. VisBiz derives a new process flow matrix to link the process of multiple circular graphs as the analyst introduces more parameters for further analysis. The results of the real-world credit card fraud study show the significant advantages of this technique in finding fraud distribution patterns and root causes of frauds.
One‐Step Production of 1,3‐Butadiene from 2,3‐Butanediol Dehydration (2016)

We report the direct production of 1,3-butadiene from the dehydration of 2,3-butandiol by using alumina as catalyst. Under optimized kinetic reaction conditions, the production of methyl ethyl ketone and isobutyraldehyde, formed via the pinacol-pinacolone rearrangement, was markedly reduced and almost 80 % selectivity to 1,3-butadiene and 1,3-butadiene could be achieved. The presence of water plays a critical role in the inhibition of oligomerization. The amphoteric nature of γ-Al2 O3 was identified as important and this contributed to the improved catalytic selectivity when compared with other acidic catalysts.

Optimization of the composition in a composite material for microelectronics application using the Ising model (2021)

Tailored material is necessary in many industrial applications since material properties directly determine the characteristics of components. However, the conventional trial and error approach is costly and time-consuming. Therefore, materials informatics is expected to overcome these drawbacks. Here, we show a new materials informatics approach applying the Ising model for solving discrete combinatorial optimization problems. In this study, the composition of the composite, aimed at developing a heat sink with three necessary properties: high thermal dissipation, attachability to Si, and a low weight, is optimized. We formulate an energy function equation concerning three objective terms with regard to the thermal conductivity, thermal expansion and specific gravity, with the composition variable and two constrained terms with a quadratic unconstrained binary optimization style equivalent to the Ising model and calculated by a simulated annealing algorithm. The composite properties of the composition selected from ten constituents are verified by the empirical mixture rule of the composite. As a result, an optimized composition with high thermal conductivity, thermal expansion close to that of Si, and a low specific gravity is acquired.
<title>P-type InGaAsP coolers for integrated optic devices</title> (2001)

Single stage thin film coolers based on thermoelectric and thermionic cooling in p-type InGaAsP superlattice structures have been fabricated. Devices with different sizes and at various ambient temperatures have been characterized. Experimental results showed 0.5 degree centigrade cooling below the ambient temperature at 25C. This cooling over 1 4mu2m thick superlattice barrier corresponds to cooling power densities on the order of 200 W/cm<SUP>2</SUP>. The device cools by a factor of two better at higher temperatures (70C). This is due to the reduction of the superlattice thermal conductivity and the broadening of the electronic distribution function at higher temperatures. 150x150 micrometers <SUP>2</SUP> devices provide largest cooling at room temperature while the optimum device size shrinks as the temperature increases. Simulations results that take into account finite thermal resistance of the InP substrate, the effect of the contact resistance, heat generation in the wire-bonds and metallic pads on top of the device predict accurately the optimum cooling of these micro refrigerators. By eliminating the major parasitic sources of heating (Joule heating in the substrate, heat conduction through the side contact and reducing the contact resistance to 5x7<SUP>-7</SUP> ohm-cm<SUP>2</SUP>) simulations show that, ultimately, one can achieve 15 degree(s)C cooling (10's of kW/cm<SUP>2</SUP> cooling power) with single stage p-InGaAsP thin film coolers.
Production and Characterization of Monoclonal Antibodies Against Amino-Terminus of Human α-Atrial Natriuretic Polypeptide (1987)

Monoclonal antibodies directed against human, alpha-atrial natriuretic polypeptide (alpha-ANP; Human, 1-28) were obtained by somatic cell fusion between P3-X63-Ag8.653 myeloma cells and spleen cells from a BALB/c mouse immunized with human, alpha-ANP selectively coupled to keyhole limpet hemocyanin. From the analysis of polyclonal sera with respect to determinant specificity before the fusion, the strategy was primarily used to pick up monoclonal antibody specific for the N-terminal residues of human, alpha-ANP. Screening of antibodies in the hybridoma culture supernatants were performed by binding to iodinated synthetic human, alpha-ANP. Two stable clones producing anti-human, alpha-ANP antibodies, designated 13A1 and 10B1, were obtained by the limiting dilution technique. The ability of ANP(Rat, 1-28) to inhibit binding of 125I-human, alpha-ANP to these antibodies was almost equipotent to ANP(human, 1-28). However, ANP fragments (Human, 7-28) and (18-28) did not compete the binding completely. These results suggest that both 13A1 and 10B1 monoclonal antibodies can specifically recognized N-terminus of human, alpha-ANP, and may be a useful tool to investigate receptor binding of human, alpha-ANP by the antagonizing effect.
Promising Cerebral Blood Flow Enhancers in Acute Ischemic Stroke (2022)

Ischemic stroke presents a major global economic and public health burden. Although recent advances in available endovascular therapies show improved functional outcome, a good number of stroke patients are either ineligible or do not have access to these treatments. Also, robust collateral flow during acute ischemic stroke independently predicts the success of endovascular therapies and the outcome of stroke. Hence, adjunctive therapies for cerebral blood flow (CBF) enhancement are urgently needed. A very clear overview of the pial collaterals and the role of genetics are presented in this review. We review available evidence and advancement for potential therapies aimed at improving CBF during acute ischemic stroke. We identified heme-free soluble guanylate cyclase activators; Sanguinate, remote ischemic perconditioning; Fasudil, S1P agonists; and stimulation of the sphenopalatine ganglion as promising potential CBF-enhancing therapeutics requiring further investigation. Additionally, we outline and discuss the critical steps required to advance research strategies for clinically translatable CBF-enhancing agents in the context of acute ischemic stroke models.
Deep Splitting and Merging for Table Structure Decomposition (2019)

Given the large variety and complexity of tables, table structure extraction is a challenging task in automated document analysis systems. We present a pair of novel deep learning models (Split and Merge models) that given an input image, 1) predicts the basic table grid pattern and 2) predicts which grid elements should be merged to recover cells that span multiple rows or columns. We propose projection pooling as a novel component of the Split model and grid pooling as a novel part of the Merge model. While most Fully Convolutional Networks rely on local evidence, these unique pooling regions allow our models to take advantage of the global table structure. We achieve state-of-the-art performance on the public ICDAR 2013 Table Competition dataset of PDF documents. On a much larger private dataset which we used to train the models, we significantly outperform both a state-ofthe-art deep model and a major commercial software system.
The global public inclusive infrastructure (GPII) (2013)

The incidence of disabilities is increasing as our population ages and we find that access to ICT is becoming mandatory for meaningful participation, independence, and self-sustenance. However we are not only nowhere near providing access to everyone who needs it, but we are actually losing ground due to reasons such as technical proliferation across platforms, increasing product churn (breaking existing solutions), decreasing social resources to address it, and an inability to effectively serve the tails of these populations because of the higher cost to do so. This poster describes the Cloud4all and Prosperity4All projects and progress in building the Global Public Inclusive Infrastructure (GPII), an infrastructure based on cloud, web and platform technologies that can increase dissemination and international localization while lowering the cost to develop, deploy, market, and support a broad range of access solutions.
ADVANCED HYDROGEN TRANSPORT MEMBRANES FOR VISION 21 FOSSIL FUEL PLANTS (2003)

Eltron Research Inc. and team members CoorsTek, Sued Chemie, Argonne National Laboratory, and NORAM are developing an environmentally benign, inexpensive, and efficient method for separating hydrogen from gas mixtures produced during industrial processes, such as coal gasification. This project was motivated by the National Energy Technology Laboratory (NETL) Vision 21 initiative, which seeks to economically eliminate environmental concerns associated with the use of fossil fuels. Over the past 12 months, this project has focused on four basic categories of dense membranes: (1) mixed conducting ceramic/ceramic composites, (2) mixed conducting ceramic/metal (cermet) composites, (3) cermets with hydrogen permeable metals, and (4) layered composites containing hydrogen permeable alloys. Ultimately, these materials must enable hydrogen separation at practical rates under ambient and high-pressure conditions, without deactivation in the presence of feedstream components such as carbon dioxide, water, and sulfur. The ceramic/ceramic composites demonstrate the lowest hydrogen permeation rates, with a maximum of approximately 0.1 mL/min/cm{sup 2} for 0.5-mm thick membranes at 800 to 950 C. Under equivalent conditions, cermets achieve a hydrogen permeation rate near 1 mL/min/cm{sup 2}, and the metal phase also improves structural stability and surface catalysis for hydrogen dissociation. Furthermore, if metals with high hydrogen permeability are used in cermets, permeation rates near 4 mL/min/cm{sup 2} are achievable with relatively thick membranes. Layered composite membranes have by far the highest permeation rates with a maximum flux in excess of 200 mL {center_dot} min{sup -1} {center_dot} cm{sup -2}. Moreover, these permeation rates were achieved at a total pressure differential across the membrane of 450 psi. Based on these results, effort during the next year will focus on this category of membranes. This report contains long-term hydrogen permeation data over eight-months of continuous operation, and permeation results as a function of operating conditions at high pressure for layered composite membranes. Additional progress with cermet and thin film membranes also is presented.
Approximate R-symmetries and the µ term (2010)

We discuss the role of approximate U(1)R symmetries for the understanding of hierarchies in Nature. Such symmetries may explain a suppressed expectation value of the superpotential and provide us with a solution to the MSSM μ problem. We present various examples in field theory and string-derived models. © SISSA 2010.
(Ga,Mn)As as a digital ferromagnetic heterostructure (2000)

(Ga,Mn)As digital ferromagnetic heterostructures are grown by incorporating submonolayer planes of MnAs into GaAs using molecular beam epitaxy. Structural and magnetic measurements indicate single-crystalline superlattice structure and ferromagnetic order with Curie temperatures (TC) up to 50 K. By varying the spacing between neighboring Mn layers, we observe that TC initially decreases with increasing spacer thickness, followed by a regime with weak dependence on the spacer thickness. The persistence of ferromagnetism for interlayer spacings of at least 200 ML (∼560 Å) suggests that the individual Mn layers are ferromagnetic.

Screening for 3D Environments That Support Human Mesenchymal Stem Cell Viability Using Hydrogel Arrays (2008)

In this study we generated 3D poly(ethylene glycol) (PEG) hydrogel arrays to screen for the individual and combinatorial effects of extracellular matrix (ECM) degradability, cell adhesion ligand type, and cell adhesion ligand density on human mesenchymal stem cell (hMSC) viability. In particular, we explored the influence of two well-characterized ECM-derived cell adhesion ligands: the fibronectin-derived Arg-Gly-Asp-Ser-Pro (RGDSP) sequence, and the laminin-derived Ile-Lys-Val-Ala-Val (IKVAV) sequence. PEG network degradation, the RGDSP ligand, and the IKVAV ligand each individually increased hMSC viability in a dose-dependent manner. The RGDSP ligand also improved hMSC viability in a dose-dependent manner in degradable PEG hydrogels, while the effect of IKVAV was less pronounced in degradable hydrogels. Combinations of RGDSP and IKVAV promoted high viability of hMSCs in nondegradable PEG networks, while the combined effects of the ligands were not significant in degradable PEG hydrogels. Although hMSC spreading was not commonly observed within PEG hydrogels, we qualitatively observed hMSC spreading after 5 days only in degradable PEG hydrogels prepared with 2.5 mM of both RGDSP and IKVAV. These results suggest that the enhanced throughput approach described herein can be used to rapidly study the influence of a broad range of ECM parameters, as well as their combinations, on stem cell behavior.
