Solution Processed PEDOT Analogues in Electrochemical Supercapacitors (2016)

We have designed fully soluble ProDOTx-EDOTy copolymers that are electrochemically equivalent to electropolymerized PEDOT without using any surfactants or dispersants. We show that these copolymers can be incorporated as active layers in solution processed thin film supercapacitors to demonstrate capacitance, stability, and voltage similar to the values of those that use electrodeposited PEDOT as the active material with the added advantage of the possibility for large scale, high-throughput processing. These Type I supercapacitors provide exceptional cell voltages (up to 1.6 V), highly symmetrical charge/discharge behavior, promising long-term stability exceeding 50 000 charge/discharge cycles, as well as energy (4-18 Wh/kg) and power densities (0.8-3.3 kW/kg) that are comparable to those of electrochemically synthesized analogues.
Integrated CMOS Energy Harvesting Converter with Digital Maximum Power Point Tracking for a Portable Thermophotovoltaic Power Generator (2015)

This paper presents an integrated maximum power point tracking system for use with a thermophotovoltaic (TPV) portable power generator. The design, implemented in 0.35 μm CMOS technology, consists of a low-power control stage and a dc-dc boost power stage with soft-switching capability. With a nominal input voltage of 1 V, and an output voltage of 4 V, we demonstrate a peak conversion efficiency under nominal conditions of over 94% (overall peak efficiency over 95%), at a power level of 300 mW. The control stage uses lossless current sensing together with a custom low-power time-based ADC to minimize control losses. The converter employs a fully integrated digital implementation of a peak power tracking algorithm, and achieves a measured tracking efficiency above 98%. A detailed study of achievable efficiency versus inductor size is also presented, with calculated and measured results.

Prostate Apoptosis in Response to Castration in Wild‐Type and Nerve Growth Factor‐Induced Gene A‐Deficient Mice (1999)

Objective : Nerve growth factor‐induced gene A (NGFIA) is a transcription factor implicated in androgen deprivation‐induced apoptosis in an androgen‐sensitive prostate cell line ( 1 , 2 ). The objective of our study was to investigate the role of NGFIA in prostate apoptosis in response to androgen ablation in a mouse animal model lacking the gene. Materials and Methods : Wild‐type mice ( n = 56) and NGFIA‐deficient mice (“knock‐out”) ( n = 16) were surgically castrated. The animals were killed at 0 (noncastrated controls), 1, 3, 5, 7, 10, 14, and 21 days after castration, and the prostates were harvested. Tissue sections were stained for morphologic analysis and quantification of apoptosis using a terminal deoxynucleotidyl transferase biotinylated deoxyuridine triphosphate nick‐end labeling (TUNEL) strategy. Apoptosis was quantitatively measured by counting the number of TUNEL‐positive cells/100 epithelial cells by light microscopy. The percentage of apoptosis was compared for wild‐type mice versus NGFIA‐deficient mice after castration at the defined time points. Results : We found a statistically significant increase in the mean percentage of prostate cell apoptosis within 7–21 days after castration in both wild‐type and NGFIA‐deficient mice ( p &lt; 0.05). However, there was no statistically significant difference in the mean percentage of apoptotic prostate cells between wild‐type and NGFIA‐deficient mice 1–5 or 7–21 days after castration ( p &gt; 0.05). Conclusion : NGFIA does not seem to play a critical role in prostate apoptosis induced by androgen ablation in this mouse model.

Design of an optical lens for LED lighting using a hybrid principal components analysis–Taguchi method (2018)

Optical lenses are extensively used to enhance the performance of light-emitting diodes. Both uniformity and efficiency are important performance indicators in lens design; however, improving uniformity always lowers efficiency. In this study, the Taguchi method and principal component analysis (PCA) are integrated to optimise the lens shape for two quality objectives, namely, uniformity and efficiency. The Taguchi method was conducted twice to establish the signal/noise ratio of the two quality characteristics for calculating the principal components in PCA. Then, the optimum parameters obtained by the Taguchi method were processed by PCA. The correlated individual responses were converted to the principal components which explained most of the dataset and were considered as the single quality characteristic for the optimisation. The combined method resolved the difficulties of optimising multiple quality characteristics without sacrificing any particular quality characteristic while the traditional Taguchi method can only be applied to the single quality characteristic. A LED light source fitted with a secondary lens designed by the proposed method showed over 92% light efficiency and an improvement in uniformity.
A Predictive Shortest-Horizon Voltage Control Algorithm for Non-Minimum Phase Three-Phase Rectifiers (2022)

Three-phase active front end rectifiers are a widely used power topology in applications such as renewable energy interfaces and motor drives, among many others. Its control is usually performed by a cascade combination of linear controllers which must be properly tuned for correct operation, and which depend on the operating point and system parameters. These family of controllers place inherent limits on the system dynamic response. On the other hand, the predictive control approach has been proposed as an alternative technique for these converters due to its fast dynamic response, simple concept, flexibility, multiple objective capability, among other desirable properties. In the case of power converter applications, short prediction horizons are usually used due to computational limitations. However, when short horizons are considered, the non-minimum phase characteristic of the rectifier voltage response can introduce stability issues, as its direct inversion is not possible without jeopardizing it. Indeed, this may lead to voltage regulation loss, and in the worst case, overcurrents that could damage the converter. To overcome such problem, this paper proposes a new concept for a predictive horizon one voltage controller for grid-connected three-phase active front end rectifiers. The proposal is based on the minimum and non-minimum phase plant factorization concept and the use of different sampling periods, to prevent the direct inversion of the non-minimum phase voltage dynamic. Simulated and experimental results are included and show its correct operation, even with a horizon one predictive voltage controller, thus ensuring the fastest response of the system for a given sampling time.
Interplay between Cubic and Hexagonal Phases in Block Copolymer Solutions (2005)

The phase behavior of a symmetric styrene-isoprene (SI) diblock copolymer in a styrene-selective solvent, diethylphthalate, was investigated by in situ small-angle X-ray scattering on isotropic and shear-oriented solutions and by rheology and birefringence. A remarkable new feature in this phase diagram is the coexistence of both body-centered cubic (bcc) and hexagonally close-packed (hcp) sphere phases, in a region between close-packed spheres (cps) and hexagonally packed cylinders (hex) over the concentration range phi approximately 0.33-0.45. By focusing on the transitions among these various ordered phases during heating and cooling cycles, we observed a strong hysteresis: supercooled cylinders persisted upon cooling. The stability of these supercooled cylinders is quite dependent on concentration, and for phi > or = 0.40, the supercooled cylinders do not revert to spheres even after quiescent annealing for 1 month. The spontaneous formation of spheres due to the dissociation of cylinders is kinetically hindered in this case, and the system is apparently not amenable to any pretransitional fluctuations of cylinders prior to the cylinder-to-sphere transition. This contrasts with the case of cylinders transforming to spheres upon heating in the melt. The application of large amplitude shear to the supercooled cylinders is effective in restoring the equilibrium sphere phases.
Charge‐assisted ultrafiltration membranes for monovalent ions separation in electrodialysis (2017)

ABSTRACT Selectivity for monovalent ions is a very important feature of ion exchange membranes in view of a further expansion of the scope of electrodialysis (ED). An efficient one‐step chemical process to graft a thin polyaniline (PANI) layer on the surface and pores of an ultrafiltration (UF) membrane is reported. The existence of a PANI layer on such modified UF membrane was confirmed by Fourier transform infrared spectroscopy and scanning electron microscopy images. These membranes were extensively characterized by studying their properties such as water uptake, ion‐exchange capacity, contact angle, and performance in diffusion dialysis. ED experiments were conducted by comparing desalting of sodium chloride and magnesium chloride solutions. During the desalting procedure, the driving force has two contributions, the electrical field and the salinity‐gradient. Initially, transport of ions by the electrical field is dominant, while at the end of the experiment, diffusion dialysis by the salinity gradient plays a larger role in ion transport. The presence of PANI can hinder Mg 2+ transport from the concentrate to the diluate compartment because of the electrostatic effect, while there is no obvious effect on Na + ions. The ability of such a surface modification layer to improve the membrane selectivity for Na + /Mg 2+ was confirmed by means of ED in a mixed solution. The flux of Na + was slightly increased to 13.21 × 10 −8 mol/L/min while the flux of Mg 2+ was reduced to 3.32 × 10 −8 mol/L/min, so that the permselectivity is almost doubled. The protonation reaction of the PANI layer creates positive charges, thus leading to an electrical repulsion barrier, which may reduce the penetration of divalent cations with respect to monovalent ions. Polyacrylonitrile‐based UF membranes with different molecular cutoff was used to determine the influence of the permselectivity. Results showed that the membrane permselectivity of smaller molecular cutoff UF membranes is higher. It can be concluded that this method is suitable for preparing membranes based on UF membranes for efficient separation of monovalent ions by electro‐driven separation techniques. © 2017 Wiley Periodicals, Inc.

Hardware and Fluid in the Loop Testing: The Application to the Testing of Fluid Systems, Some Examples and Applications (2015)

Mastering the art of ‘mechatronics’ currently looks like one of the most attractive tasks of modern engineering technology and science. Many applications resort to the interdisciplinary approach of mechatronics to enhance the performance, quality and safety of either product or process. Some are very traditional (like hard disk drives, biomedical, automotive and aerospace systems) while others are fairly new (like micro and nano electromechanical systems, unmanned air vehicles, intelligent machining, manufacturing systems or bioinspired devices). This book describe some practical examples, which demonstrate how different competences, disciplines and technologies meet in an innovative mechatronic system. They deal with several domains like the hard disk drive technology, biomedical prostheses, fluidic automation, UAV Vision System, vibration monitoring and suppression in steelmaking plants, materials machining and smart composites. These examples will show the reader, who is still looking for the real meaning of mechatronics, how some innovative technologies allow implementing a sort of artificial intelligence in several systems currently produced. Examples describe neural network positioning control, chaos prevention, myoelectric stimulation of prosthesis, human detection by vision system, multi-physics modeling and control of dynamics. Some topics are related to small scale, as in the case of a finger of a biotronic hand. Nevertheless, the same approach is applied even to huge machines, like the electric arc furnace. It is worth noticing that the authors resorted even to the additive manufacturing, as in prototyping bio-prostheses, or to fiber optics embedded into composite structures. Those technologies allow reducing cost, weight or volume of product. In some cases, the mechatronic approach improves the quality and the accuracy of some material processing, like in rolling or in turning against the risk of self–excited chatter vibration. The examples described in this book cover a wide range of mechatronic applications. (Imprint: Nova)
Immunoelectrophoresis of ligandin. (1979)

Procedures are described that facilitate the immunoelectrophoretic analysis of the carcinogen-binding protein ligandin. Rocket immunoelectrophoresis is performed at pH 4.9 in agarose gel containing carbamylated antiserum thereby promoting more rapid migration of ligandin, pI 9.0, into the gel. This method is used as a basis for quantitative crossed immunoelectrophoresis using either electrophoresis or isoelectrofocusing of ligandin in the first dimension.
Interpreting and Predicting Tactile Signals via a Physics-Based and\n Data-Driven Framework (2020)

High-density afferents in the human hand have long been regarded as essential\nfor human grasping and manipulation abilities. In contrast, robotic tactile\nsensors are typically used to provide low-density contact data, such as\ncenter-of-pressure and resultant force. Although useful, this data does not\nexploit the rich information content that some tactile sensors (e.g., the\nSynTouch BioTac) naturally provide. This research extends robotic tactile\nsensing beyond reduced-order models through 1) the automated creation of a\nprecise tactile dataset for the BioTac over diverse physical interactions, 2) a\n3D finite element (FE) model of the BioTac, which complements the experimental\ndataset with high-resolution, distributed contact data, and 3)\nneural-network-based mappings from raw BioTac signals to low-dimensional\nexperimental data, and more importantly, high-density FE deformation fields.\nThese data streams can provide a far greater quantity of interpretable\ninformation for grasping and manipulation algorithms than previously\naccessible.\n
Vertebroplasty for Osteoporotic Compression Fractures: Current Practice and Evolving Techniques (2002)

Perutaneous vertebroplasty was developed in France by Deramond et al., who provided initial reports of the procedure in 1987. This minimally invasive procedure uses a large-bore bone-cutting needle to percutaneously access a vertebral body, inject bone cement, and thereby stabilize and reinforce the remaining bone structure. The procedure was used initially to treat aggressive hemangiomas, but it then was extended to the treatment of osteolytic metastases and myeloma and currently osteoporotic compression fractures refractory to medical therapy. In this article, we review the current technique and its indications along with emerging devices and areas of current research.
Abstract 2702: The mTOR complex 2-associated interactome and cell migration ability determination in brain cancers (2018)

Abstract The mechanistic target of rapamycin complex 2 (mTORC2) is a multiprotein complex driving several cellular processes to promote metabolic activities, cell survival, cell proliferation, DNA damage control, and cell motility. It has been implicated as a critical player in tumorigenesis, metabolic reprogramming, and promotion of cancer aggressiveness. Since the functions of this particular complex have not been well understood, the characterization of mTORC2 and its signaling pathway is necessary for better understanding of known mTORC2-mediated function, to define new roles, and to identify more mTORC2 interacting partners in cancers, particularly ones with hyperactivated mTORC2 such as glioblastoma multiforme. GBM has been claimed as one of the most aggressive type cancers. In GBM cells, mTORC2 was reported to be regulating glioblastoma migration and invasion through the control of actin cytoskeleton reorganization and filamin A. Previously, we characterized mTORC2 by proteomic analysis using affinity purification coupled to mass spectromytry (AP-MS) technique. We were able to identify protein-protein interactions between RICTOR, a specific component of mTORC2, and associated proteins and revealed a number of mTORC2 interacting partners that have never been reported. These proteins include low-abundance proteins and less-characterized proteins. In this work, we further investigated more insights about the differences of mTORC2-associated interactomes under various conditions affecting cancer cell migration. We found the comparison between low-grade and high-grade glioma cell lines shows distinct groups of RICTOR-bound proteins. In addition, we have carried out migration assays and immunofluorescence staining experiments to determine cancer cell migration and localization of RICTOR and some of identified proteins under each culture condition. The results suggested that the information from proteomic analysis correlated with intracellular RICTOR localization and cell migration ability. EMT proteins and more cytoskeletal proteins were found in more motile and more invasive cells while nuclear proteins were identified when using low-grade glioma cells. Furthermore, we were able to use this approach to investigate cancer cell lines from other organs and found some relevance between mTORC2 complex localization and cell migration. Ultimately, these results will be analyzed together with the expression of other potential cancer markers to help determine the characteristics of brain cancers.

Constraints on models of scalar and vector leptoquarks decaying to a quark and a neutrino at s=13  TeV (2018)

The results of a previous search by the CMS Collaboration for squarks and gluinos are reinterpreted to constrain models of leptoquark (LQ) production. The search considers jets in association with a transverse momentum imbalance, using the ${M}_{\mathrm{T}2}$ variable. The analysis uses proton-proton collision data at $\sqrt{s}=13\text{ }\text{ }\mathrm{TeV}$, recorded with the CMS detector at the LHC in 2016 and corresponding to an integrated luminosity of $35.9\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$. Leptoquark pair production is considered with LQ decays to a neutrino and a top, bottom, or light quark. This reinterpretation considers higher mass values than the original CMS search to constrain both scalar and vector LQs. Limits on the cross section for LQ pair production are derived at the 95% confidence level depending on the LQ decay mode. A vector LQ decaying with a 50% branching fraction to $t\ensuremath{\nu}$, and 50% to $b\ensuremath{\tau}$, has been proposed as part of an explanation of anomalous flavor physics results. In such a model, using only the decays to $t\ensuremath{\nu}$, LQ masses below 1530 GeV are excluded assuming the Yang-Mills case with coupling $\ensuremath{\kappa}=1$, or 1115 GeV in the minimal coupling case $\ensuremath{\kappa}=0$, placing the most stringent constraint to date from pair production of vector LQs.
Characterization of the fimA gene encoding bundle-forming fimbriae of the plant pathogen Xanthomonas campestris pv. vesicatoria (1997)

The fimA gene of Xanthomonas campestris pv. vesicatoria was identified and characterized. A 20-mer degenerate oligonucleotide complementary to the N-terminal amino acid sequence of the purified 15.5-kDa fimbrillin was used to locate fimA on a 2.6-kb SalI fragment of the X. campestris pv. vesicatoria 3240 genome. The nucleotide sequence of a 1.4-kb fragment containing the fimA region revealed two open reading frames predicting highly homologous proteins FimA and FimB. FimA, which was composed of 136 amino acids and had a calculated molecular weight of 14,302, showed high sequence identity to the type IV fimbrillin precursors. fimB predicted a protein product of 135 amino acids and a molecular weight of 13,854. The open reading frame for fimB contained near the 5' end a palindromic sequence with a terminator loop potential, and the expression level of fimB in vitro and in Xanthomonas was considerably lower than that of fimA. We detected an efficiently transcribed fimA-specific mRNA of 600 bases as well as two weakly expressed, longer mRNA species that reacted with both fimA and fimB. A homolog of fimA but not of fimB was detected by Southern hybridization in strains of X. campestris pv. vesicatoria, campestris, begoniae, translucens, and graminis. A fimA::omega mutant of strain 3240 was not significantly reduced in virulence or adhesiveness to tomato leaves. However, the fimA mutant was dramatically reduced in cell aggregation in laboratory cultures and on infected tomato leaves. The fimA mutant strain also exhibited decreased tolerance to UV light.
