Evaluation of Methods for Applying IEEE1584-2018 Equations for Low Voltage Current Limiting Fuses (2020)

This paper will propose methods for applying the standard equations of IEEE1584-2018 to address the issues of current limitation, the single pole nature of fuses, and current imbalance not covered by these equations. The goal is to use typical fuse data such as total clearing curves and let-through current data in equations developed for prediction of arc flash hazards. This approach yields calculations consistent with the results of lab tests using current limiting fuses.

Dioxole functionalized metal–organic frameworks (2013)

The synthesis and physical properties of dioxole functionalized metal-organic frameworks (MOFs) are reported. Combination of benzo[d][1,3]dioxole-4,7-dicarboxylic acid (dioxole-BDC) and Zn(II) under solvothermal conditions yields either an isoreticular metal-organic framework analog (IRMOF-1-dioxole) or a new MOF material (MOF-1-dioxole). With the addition of a co-ligand, namely 4,4'-bipyridine, a mixed-linker Zn(II)-paddlewheel MOF (BMOF-2-dioxole) is obtained. The structure of all three MOFs has been determined by single-crystal X-ray diffraction studies. MOF-1-dioxole reveals that the dioxole group binds to the Zn(II) ions, while there is no such binding in IRMOF-1-dioxole or BMOF-2-dioxole, hence preserving the parent topology of these frameworks. Thermal gravimetric analysis and gas sorption studies reveal quite different physical properties for each of these functionalized MOFs.

A closed-form unsupervised geometry-aware dimensionality reduction method in the Riemannian Manifold of SPD matrices (2017)

Riemannian geometry has been found accurate and robust for classifying multidimensional data, for instance, in brain-computer interfaces based on electroencephalography. Given a number of data points on the manifold of symmetric positive-definite matrices, it is often of interest to embed these points in a manifold of smaller dimension. This is necessary for large dimensions in order to preserve accuracy and useful in general to speed up computations. Geometry-aware methods try to accomplish this task while respecting as much as possible the geometry of the original data points. We provide a closed-form solution for this problem in a fully unsupervised setting. Through the analysis of three brain-computer interface data bases we show that our method allows substantial dimensionality reduction without affecting the classification accuracy.
Customized Filter Cube in Fluorescence Microscope Measurements of InGaN/GaN Quantum-Well Characterization (2009)

Modified optical filter elements were fabricated to access blue and violet spectral ranges of InGaN/GaN light-emitting diodes (LEDs) in characterizing luminescence via a fluorescence microscope. As band gap energies of GaN and InGaN layers were close, it was not trivial to separate excitation and luminescence light, which caused slight detection of excitation light. Nevertheless, the results obtained on c- and m-plane LEDs were compared with our previous work, leading consistent understanding of luminescence characteristics in terms of the quantum-confined Stark effect.
Scintillation Light Yields of Tb-doped SiO2 Glasses (2023)

We investigated the scintillation light yields of Tb-doped SiO 2 glasses.We prepared 0.05, 0.1, and 0.5% Tb-doped SiO 2 glasses by melting and solidifying sintered ceramic rods using an oxygen burner.The obtained samples showed no crystalline phases in X-ray diffraction measurements.Pulse height spectra of the Tb-doped SiO 2 samples were measured under γ-ray excitation using a measurement system for slow decay pulses.The number of channels at the Compton edge of the 0.5% Tb-doped sample was the highest and was approximately 50% of that of a commercial lithium glass scintillator (GS20).By considering the light yield of GS20 and the wavelength dependence of the quantum efficiency of the photomultiplier tube, the light yield of the 0.5% Tb-doped SiO 2 sample was estimated as 3800 photons/MeV.
Identification of volatile constituents of beer using resin adsorption and chiral GCMS. Correlation with malt type and brewing method (2009)

Beer is a widely consumed and widely studied alcoholic beverage. The beer aroma is influenced by several factors like the plant origin of the used malt (barley, wheat), the use of additional cereals (corn, wheat, barley, rice), the brewing methodology, the hop variety etc. A new methodology for the study of the volatile constituents of beer using adsorption resin was carried out for the first time. The same methodology had been successfully applied in grape distillates [1]. The isolation of volatile components was based on their adsorption on XAD4 resin. The beer sample without any treatment was passed through a column containing XAD4 resin and the adsorbed volatile components were desorbed using diethylether/pentane (1:1) which was then carefully evaporated. The residue was analyzed by GC-MS on a chiral β-Dex sm column. Twenty commercial samples belonging to the three major beer classes (lager, ale, lambic) were studied. In all cases phenylethanol (25–45%) and 3-methylbutanol (20–40%) were identified as the major constituents. Several differences were observed among the &gt;70 identified constituents related mainly with the malt type and the brewing method. Interestingly, 2(3H)-benzoxazolone (1), a known phytoalexin of wheat, was found only in beers prepared using wheat malt. Additionally, tryptophol acetate (2) was for the first time identified as a beer constituent and it was found to be restricted to ale beers.
<title>Porous silicon process for encapsulated single-crystal surface-micromachined microstructures</title> (1999)

This paper describes a 10-mask process for fabricating single crystal, surface micromachined devices by using porous silicon as a sacrificial layer, and an n-type epitaxial layer for structural material. Single crystal structures have the important advantage over polysilicon structures of precisely controlled material properties, in particular Young's Modulus and residual strain. Additionally, the epitaxial layer is suitable for integrating circuitry, and provides a promising alternative for integrated microsystems. This results in a process with similar flexibility in device design to a polysilicon surface micromachined process, but with the control of a bulk silicon technology. The process also includes provisions for device encapsulation in vacuum using reactive sealing of the microstructure with an LPCVD polysilicon layer. Although this technology is versatile and can be used for a variety of microstructures, the primary demonstration vehicles used in this research effort have been resonators. Some of the key problems is using porous silicon processes include: dimensional control of the porous silicon region; creating a high aspect ratio porous silicon region; eliminating defects induced by the porous silicon process in the remaining silicon structure; and protection of the oxidized porous silicon from etching prior to sacrificial etch.

340 Is catheter ablation of atrial fibrillation worthwhile in patients with congestive heart failure and concurrent structural heart disease? (2005)

Background: biatrial pacing can be more effective than standard right atrial pacing in preventing the incidence of atrial fibrillation (A Fib) after coronary artery bypass surgery (CABG).The purpose of this study was to evaluate the efficacy of overdrive biatrial epicardial pacing in preventing post-CABG A Fib and hemodynamic benefits.Methods and results: a total of 72 patients (M/F: 48/24, Age: 66yrs) who underwent CABG were assigned to biatrial triggered pacing (Bi-AAT; n=50) or right atrial single pacing (RA-AAI; n=22).Furthermore, hemodynamic effects of biatrial pacing were examined by Swan-Ganz catheter and echocardiography.The incidence rate of A Fib was significantly reduced in the Bi-AAT group (11/50 (22.0%)) compared with the RA-AAI group (13/22 (59.1%),P<0.01).Cardiac output was significantly increased and PAWP was significantly decreased at Bi-AAT pacing compared with RA-AAI pacing.The height of E wave (65.2 cm/sec vs 57.8, P<0.05) was significantly increased by Bi-AAT pacing.Especially, the incidence of A Fib was significantly reduced in overdrive pacing group (4/29 (13.8%)) compared with the spontaneous group (7/21 (33.3%),P<0.05).Furthermore, the number of atrial premature contraction was suppressed in overdrive pacing group.Conclusion: biatrial triggered epicardial pacing is well tolerated and significantly reduces the incidences of post CABG A Fib. Hemodynamic improvement and overdrive pacing effect may play a role in this beneficial result.
Depleting dietary valine permits nonmyeloablative mouse hematopoietic stem cell transplantation (2016)

A specialized bone marrow microenvironment (niche) regulates hematopoietic stem cell (HSC) self-renewal and commitment. For successful donor-HSC engraftment, the niche must be emptied via myeloablative irradiation or chemotherapy. However, myeloablation can cause severe complications and even mortality. Here we report that the essential amino acid valine is indispensable for the proliferation and maintenance of HSCs. Both mouse and human HSCs failed to proliferate when cultured in valine-depleted conditions. In mice fed a valine-restricted diet, HSC frequency fell dramatically within 1 week. Furthermore, dietary valine restriction emptied the mouse bone marrow niche and afforded donor-HSC engraftment without chemoirradiative myeloablation. These findings indicate a critical role for valine in HSC maintenance and suggest that dietary valine restriction may reduce iatrogenic complications in HSC transplantation.
Evolution comparée de quelques paramètres minéraux, de l'ostéocalcine, du 25(OH)D et du 1,25(OH)2D chez la chamelle du sud marocain et son chamelon nouveau-né (2000)

Dans cette étude a été établie une cinétique d'évolution post-partum des taux plasmatiques de quelques paramètres minéraux (Ca, P, Mg, Na et K), d'ostéocalcine, du 25(OH)D et du 1,25(OH)2D, chez la chamelle en lactation du Sud marocain (n = 5) et chez son nouveau-né (n = 5). Les taux plasmatiques de Ca et de P (mg/l) chez le chamelon ont été supérieurs à ceux de la mère, depuis la naissance jusqu'au 301 jour de vie. A la naissance, les taux plasmatiques de Mg, Na et K (mg/1) chez le chamelon ont été inférieurs aux valeurs maternelles. Chez le chamelon, les taux plasmatiques d'OC (ng/ml) ont été plus élevés que ceux de la mère depuis la naissance (3,4 ± 0,3 vs 0,7 ± 0,3; P &lt; 0,05) jusqu'au 30e jour postnatal (5,2 ± 0,5 vs 0,7 ± 0,3). Ces taux ont atteint leur maximum au 3e jour postnatal chez le chamelon (6,8 ± 0,5) et au 4e jour post-partum chez la chamelle (2,3 ± 0,4). Les concentrations plasmatiques (pg/ml) du 25(OH)D et du 1,25(OH)2D chez le chamelon nouveau-né ont été plus faibles à la naissance que celles de la mère (respectivement 58,2 ± 12,4 vs 480 ± 59,7, P &lt; 0,05, et 834,8 ± 61,5 vs 1 301 ± 209, P &lt; 0,05). Ces concentrations néonatales sont devenues significativement plus élevées comparativement à la mère dès le 15e jour postnatal pour le 25(OH)D (176,4 ± 19,6 vs 116,1 ± 30,4, P &lt; 0,05) et dès le 7e jour de vie pour le 1,25(OH)2D (1 215 ± 248 vs 571 ± 64, P &lt; 0,05). Ces résultats indiquent que, chez le dromadaire, l'OC pourrait être un biomarqueur fiable de la croissance osseuse néonatale et que les 25(OH)D et 1,25(OH)2D pourraient jouer un rôle prépondérant dans la régulation de l'homéostasie calcique chez le nouveau-né et chez la mère en lactation.

Researchers as well as students in the field of mobile robotics will appreciate this comprehensive treatment of state-of-the-art methods and key technologies.
On the use of lattices for the automatic generation of pronunciations (2003)

In this paper, we explore the use of lattices to generate pronunciations for speech recognition based on the observation of a few (say one or two) speech utterances of a word. Various search strategies are investigated in combination with schemes where single or multiple pronunciations are generated for each speech utterance. In our experiments, a strategy that combines merging time-overlapping links in a context-dependent subphone lattice and generating multiple pronunciations provides the best recognition accuracy. This results in average relative gains of 30% over the generation of single pronunciations using a Viterbi search.
Influence of Multiplicative Stochastic Variation on Translational\n Elongation Rates (2014)

Recent experiments have shown that stochastic effects exerted at the level of\ntranslation contribute a substantial portion of the variation in abundance of\nproteins expressed at moderate to high levels. This study analyzes\ntranslational noise arising from fluctuations in residue-specific elongation\nrates. The resulting variation has multiplicative components that lead\nindividual protein abundances in a population to exhibit approximately\nlog-normal behavior. The high variability inherent in the process leads to\nparameter variation that has the features of a type of noise in biological\nsystems that has been characterized as extrinsic. Elongation rate variation\noffers an accounting for a major component of extrinsic noise, and the analysis\nprovided here highlights a probability distribution that is a natural extension\nof the Poisson and has broad applicability to many types of multiplicative\nnoise processes.\n
Analysis of leaching and stability of microporated PEG spheres for fluorescent analyte detection (2006)

Poly(ethylene glycol) (PEG) microspheres have been used to sense a variety of analytes by encapsulating fluorescently labeled molecules into a PEG hydrogel matrix. This matrix is designed to retain the sensing molecules while simultaneously allowing nearly unhindered analyte diffusion. Some sensing assays, however, depend on the conformational rearrangement or binding of large macromolecular compounds which may be sterically prohibited in a dense polymer matrix. A new microporation process has been developed in order to create small cavities in the spheres containing aqueous solution and the assay components. This configuration insures a small mesh size for the supporting polymer, which limits leaching, while allowing the large assay components space to react within the aqueous cavities. Three hydrogel compositions (100% PEG, 50% PEG hydrogels, and microporated 100% PEG) were studied by embedding traditional pH (FITC) and oxygen sensitive fluorophores (Ru(Phen)). These hydrogels were analyzed for leaching and dynamic response to evaluate the functionality of the new microporated hydrogel.
Error and attack tolerance of layered complex networks (2007)

Many complex systems may be described by not one but a number of complex networks mapped on each other in a multi-layer structure. Because of the interactions and dependencies between these layers, the state of a single layer does not necessarily reflect well the state of the entire system. In this paper we study the robustness of five examples of two-layer complex systems: three real-life data sets in the fields of communication (the Internet), transportation (the European railway system), and biology (the human brain), and two models based on random graphs. In order to cover the whole range of features specific to these systems, we focus on two extreme policies of system's response to failures, no rerouting and full rerouting. Our main finding is that multi-layer systems are much more vulnerable to errors and intentional attacks than they appear from a single layer perspective.
Razor clam to RoboClam: burrowing drag reduction mechanisms and their robotic adaptation (2014)

Estimates based on the strength, size, and shape of the Atlantic razor clam (Ensis directus) indicate that the animal's burrow depth should be physically limited to a few centimeters; yet razor clams can dig as deep as 70 cm. By measuring soil deformations around burrowing E. directus, we have found the animal reduces drag by contracting its valves to initially fail, and then fluidize, the surrounding substrate. The characteristic contraction time to achieve fluidization can be calculated directly from soil properties. The geometry of the fluidized zone is dictated by two commonly-measured geotechnical parameters: coefficient of lateral earth pressure and friction angle. Calculations using full ranges for both parameters indicate that the fluidized zone is a local effect, occurring between 1-5 body radii away from the animal. The energy associated with motion through fluidized substrate-characterized by a depth-independent density and viscosity-scales linearly with depth. In contrast, moving through static soil requires energy that scales with depth squared. For E. directus, this translates to a 10X reduction in the energy required to reach observed burrow depths. For engineers, localized fluidization offers a mechanically simple and purely kinematic method to dramatically reduce energy costs associated with digging. This concept is demonstrated with RoboClam, an E. directus-inspired robot. Using a genetic algorithm to find optimal digging kinematics, RoboClam has achieved localized fluidization burrowing performance comparable to that of the animal, with a linear energy-depth relationship, in both idealized granular glass beads and E. directus' native cohesive mudflat habitat.

Abstract 3931: Whole genome and whole exome sequencing of head and neck cancer (2011)

Abstract Head and neck cancer is responsible for an enormous cancer burden worldwide, with an estimated 500,000 new cases per year. However, knowledge of the spectrum of genetic alterations that drive this malignancy remains incomplete. Previous studies of this disease have identified recurrent somatic mutations in a few specific genes, but few systematic genome-scale studies have been performed. Accordingly, we have undertaken a pilot study of complete genome/exome characterization in this malignancy. We obtained genomic DNA from 40 head and neck tumors together with matched normal DNA from whole blood. To date, we have obtained whole exome sequencing of 28 tumor/normal pairs and whole genome sequencing of two tumor/normal pairs. The average base mutation rate is 3.1 × 10-6 (range = 2.9 × 10-7 to 8.8 × 10-6), consistent with rates observed in lung cancer and other tobacco-related malignancies. We also identified 24 high-confidence somatic rearrangements in one sample and 120 in the other sample (including 7 and 44 inter-chromosomal rearrangements, respectively). In addition to frequent mutations of TP53 (53%), HRAS, PIK3CA, and PTEN, we also observed other recurrently mutated genes that implicate several oncogenic pathways. Furthermore, layering of somatic mutation data onto known pathway information strengthens the evidence for several oncogenic processes not previously implicated in head and neck cancer. Altogether, these data should enhance our understanding of the mechanisms that drive head and neck carcinogenesis and progression and may also illuminate new therapeutic opportunities.
