Lumped parameter modeling as a predictive tool for a battery status monitor (2003)

The Advanced Technology Development Program is currently evaluating the performance of the second generation of lithium-ion cells (i.e., Gen 2 cells). Both the Gen 2 Baseline and Variant C cells are tested in accordance with the cell-specific test plan, and are removed at roughly equal power fade increments and sent for destructive diagnostic analysis. The diagnostic laboratories did not need all test cells for analysis, and returned five spare cells to the Idaho National Engineering and Environmental Laboratory (INEEL). INEEL used these cells for special pulse testing at various duty cycles, amplitudes, and durations to investigate the usefulness of the lumped parameter model as a predictive tool in a battery status monitor. The lumped parameter model is a simplified linear model that accurately predicts the voltage response during certain pulse conditions. A database of parameter trends should enable dynamic predictions of state-of-charge and state-of-health conditions during in-vehicle pulsing. This information could be used by the battery status monitor to provide accurate information to the vehicle control system.
Modificación de un horno eléctrico doméstico a incubadora de laboratorio controlada con Arduino (2018)

Teniendo en cuenta que un Horno Electrico Domestico (HED) THOMAS TH-42NO2 tiene un costo de $141,87 USD (S/ 458,24) y que su estructura y algunos elementos pueden ser utilizados, se modifico a Incubadora de Laboratorio Controlada con Arduino (ILCA) y su funcionamiento fue probado experimentalmente, con la incubacion en medio de cultivo de un microorganismo base (Rodosporidium turoloides), sensible a la temperatura. Se comprobo que no existieron diferencias significativas (p > 0,05) en su crecimiento utilizando una Incubadora de Laboratorio Comercial (ILC) y la ILCA; demostrando la eficiencia de control de la temperatura. El costo total de la ILCA fue de S/ 608,74, menor que los ILC; cuyo costo fluctua para una unidad de similar tamano en S/ 10 723,60. Lo que justifica economicamente la modificacion de un HED a una ILCA para fines de trabajos de laboratorio.
Matrix Metalloproteinase-9 Deficiency Impairs Host Defense against Abdominal Sepsis (2006)

Matrix metalloproteinase (MMP)-9 is involved in extracellular matrix degradation and leukocyte migration. To determine the role of MMP-9 in the innate immune response to peritonitis, MMP-9 gene-deficient (MMP-9(-/-)) and normal wild-type mice were i.p. infected with Escherichia coli. MMP-9 mRNA and pro-MMP-9 protein levels increased rapidly upon induction of peritonitis. Although MMP-9(-/-) neutrophils showed a normal phagocytosis of E. coli in vitro, MMP-9(-/-) mice displayed a reduced resistance against E. coli peritonitis, as indicated by an enhanced bacterial outgrowth in the peritoneal cavity and increased dissemination of the infection. Furthermore, the cytokine response to LPS was not influenced by MMP-9 deficiency. However, during E. coli peritonitis, MMP-9(-/-) mice showed much higher peritoneal chemokine and cytokine levels compared with wild-type mice. Despite the increased local chemokine concentrations, MMP-9(-/-) mice displayed a diminished recruitment of leukocytes to the site of infection, indicating that cellular migration was impaired. Moreover, MMP-9(-/-) mice developed more severe distant organ damage during infection. These data suggest that MMP-9 is an essential component of an effective host response to E. coli peritonitis.
Assembling the sea: materiality, movement and regulatory practices in the Cardigan Bay scallop fishery (2012)

This paper investigates the controversy around scallop dredging in Cardigan Bay, Wales. The area’s scallop fishery was relatively small until the 1980s but has seen dramatic increases in catches in the past five years. Concerns have been raised about the effect of increasing fishing effort, especially for its potential impacts on the Bay’s population of bottlenose dolphins, which were the basis of its designation as a Special Area of Conservation. I show that the controversy is not merely about human management of an endangered fish stock, but also involves the actions of scallops, dolphins, the sea, seabed, fishing technologies and regulatory practices. I also show that the events in Cardigan Bay frequently are co-produced by events and actions further afield. These topics are examined through the lens of assemblage theory, with which geographers have yet to widely engage. This emphasizes heterogeneity and emergence, and encourages a focus on processes of (de)territorialization. In the paper, I contrast the territorializing practices of regulatory regimes with the smoothing movements of dolphins, the sea and the seabed, showing how the actions of these nonhumans complicate attributions of environmental harm. Through this, the paper addresses the lack of attention paid to the sea by cultural geographers, particularly through a focus on materiality and multi-dimensionality.
Effects of virtual reality rehabilitation training on gait and balance in patients with Parkinson's disease: A systematic review (2019)

According to the results of this study, we found that VR rehabilitation training can not only achieve the same effect as conventional rehabilitation training. Moreover, it has better performance on gait and balance in patients with PD. Taken together, when the effect of traditional rehabilitation training on gait and balance of PD patients is not good enough, we believe that VR rehabilitation training can at least be used as an alternative therapy. More rigorous design of large-sample, multicenter randomized controlled trials are needed to provide a stronger evidence-based basis for verifying its potential advantages.

Electric Drill Stem Telemetry (1982)

Use of the drill stem-earth system for electric down-hole-to- surface telemetry at low frequencies is considered in this article. Estimates of signal attenuation for both the perfectly conducting drill stem and a drill stem with finite conductivity are obtained and compared with previously reported work. It appears that a link of several kilometers length can be operated at frequencies in the hertz range in 10-100-Ω · m earth at power levels of the order of a few watts.
Enhanced trichloroethylene dechlorination by Fe(O) (1995)

Trichloroethylene, TCE, can be effectively dechlorinated using Fe(0) and as little as 1% citric acid based upon weight of iron employed. Rate constants from batch reactions are on the order of 5.3hr{sup -1} within the pH range 5.8-6.5. Chloride mass balance from these reactions is typically between 80-95%. Carbon based byproducts will be presented based upon C-14 labelling studies. The effect of use of various buffers upon reaction products and rate will also be presented.
Slow dynamics in protein fluctuations revealed by time-structure based independent component analysis: The case of domain motions (2011)

Protein dynamics on a long time scale was investigated using all-atom molecular dynamics (MD) simulation and time-structure based independent component analysis (tICA). We selected the lysine-, arginine-, ornithine-binding protein (LAO) as a target protein and focused on its domain motions in the open state. A MD simulation of the LAO in explicit water was performed for 600 ns, in which slow and large-amplitude domain motions of the LAO were observed. After extracting domain motions by rigid-body domain analysis, the tICA was applied to the obtained rigid-body trajectory, yielding slow modes of the LAO's domain motions in order of decreasing time scale. The slowest mode detected by the tICA represented not a closure motion described by a largest-amplitude mode determined by the principal component analysis but a twist motion with a time scale of tens of nanoseconds. The slow dynamics of the LAO were well described by only the slowest mode and were characterized by transitions between two basins. The results show that tICA is promising for describing and analyzing slow dynamics of proteins.
Moving-Wire Device for Carbon Isotopic Analyses of Nanogram Quantities of Nonvolatile Organic Carbon (2005)

We describe a moving-wire analyzer for measuring 13C in dissolved, involatile organic materials. Liquid samples are first deposited and dried on a continuously spooling nickel wire. The residual sample is then combusted as the wire moves through a furnace, and the evolved CO2 is analyzed by continuous-flow isotope ratio mass spectrometry. A typical analysis requires 1 microL of sample solution and produces a CO2 peak approximately 5 s wide. The system can measure "bulk" delta13C values of approximately 10 nmol of organic carbon with precision better than 0.2 per thousand. For samples containing approximately 1 nmol of C, precision is approximately 1 per thousand. Precision and sensitivity are limited mainly by background noise derived from carbon within the wire. Instrument conditions minimizing that background are discussed in detail. Accuracy is better than 0.5 per thousand for nearly all dissolved analytes tested, including lipids, proteins, nucleic acids, sugars, halocarbons, and hydrocarbons. The sensitivity demonstrated here for 13C measurements represents a approximately 1000-fold improvement relative to existing elemental analyzers and should allow the use of many new preparative techniques for collecting and purifying nonvolatile biochemicals for isotopic analysis.
Parallel iterative solution of sparse linear systems using orderings from graph coloring heuristics (1990)

The efficiency of a parallel implementation of the conjugate gradient method preconditioned by an incomplete Cholesky factorization can vary dramatically depending on the column ordering chosen. One method to minimize the number of major parallel steps is to choose an ordering based on a coloring of the symmetric graph representing the nonzero adjacency structure of the matrix. In this paper, we compare the performance of the preconditioned conjugate gradient method using these coloring orderings with a number of standard orderings on matrices arising from applications in structural engineering. Because optimal colorings for these systems may not be a priori known: we employ several graph coloring heuristics to obtain consistent colorings. Based on lower bounds obtained from the local structure of these systems, we find that the colorings determined by these heuristics are nearly optimal. For these problems, we find that the increase in parallelism afforded by the coloring-based orderings more than offsets any increase in the number of iterations required for the convergence of the conjugate gradient algorithm.
Exploring Time Series Retrieved from Cardiac Implantable Devices for Optimizing Patient Follow-Up (2008)

Current cardiac implantable devices (IDs) are equipped with a set of sensors that can provide useful information to improve patient follow-up and prevent health deterioration in the postoperative period. In this paper, data obtained from an ID with two such sensors (a transthoracic impedance sensor and an accelerometer) are analyzed in order to evaluate their potential application for the follow-up of patients treated with a cardiac resynchronization therapy (CRT). A methodology combining spatiotemporal fuzzy coding and multiple correspondence analysis (MCA) is applied in order to: 1) reduce the dimensionality of the data and provide new synthetic indexes based on the "factorial axes" obtained from MCA; 2) interpret these factorial axes in physiological terms; and 3) analyze the evolution of the patient's status by projecting the acquired data into the plane formed by the first two factorial axes named "factorial plane." In order to classify the different evolution patterns, a new similarity measure is proposed and validated on the simulated datasets, and then, used to cluster observed data from 41 CRT patients. The obtained clusters are compared with the annotations on each patient's medical record. Two areas on the factorial plane are identified, one being correlated with a health degradation of patients and the other with a stable clinical state.
Super-resolution of mammograms (2010)

High-quality mammography is the most effective technology presently available for breast cancer screening. High resolution mammograms usually lead to more accurate diagnoses; however, they require large doses of radiation, which may have harmful effects. In this paper, we present a method to synthesize high-resolution mammograms from low-resolution inputs, which offers the potential of allowing accurate diagnoses while minimizing risks to patients. Our algorithm combines statistical machine learning methods and stochastic search to learn the mapping from low-resolution to high-resolution mammograms using a large dataset of training image pairs. Experimental results show that the super-resolution algorithm can generate high-quality, high-resolution breast mammograms from low-resolution input with no human intervention.
Effect of Insulin and Glucose Infusions on Sympathetic Nervous System Activity in Normal Man (1981)

Recent studies indicate a link between carbohydrate intake and the functional state of the sympathetic nervous system. Fasting or carbohydrate restriction decreases sympathetic activity, while glucose ingestion or dietary supplementation with sucrose increases sympathetic nerve activity. To examine the potential contributions of hyperglycemia and hyperinsulinemia to sympathetic stimulation, sympathetic activity was assessed by measurement of plasma norepinephrine (NE) levels and concomitant cardiovascular indices in nonobese young men during glucose and insulin infusions using glucose clamp techniques. In the insulin infusion studies (euglycemic glucose clamp), insulin was administered at 2 mU/kg/min and 5 mU/kg/min for 2 h while blood glucose was maintained at basal levels by a variable rate of glucose infusion. In the hyperglycemic studies, blood glucose was raised 125 mg/dl above basal and maintained at that level for 2h. In response to both insulin infusions, plasma NE rose progressively over the course of the study, increasing 50% with the 2-mU infusion (from mean basal value of 240 ± 34 pg/ml to 360 ± 41 at 150 min, P &lt; 0.001 for changes over time by analysis of variance) and 117% with the 5-mil infusion (from 254 ± 20 pg/ml to 551 ± 88 at 150 min, P &lt; 0.001). The plasma NE response was greater with the 5-mll than with the 2-mU insulin infusion (P &lt; 0.001), and similarly, was greater during the 2-mU insulin infusion than during a control test in which neither insulin nor glucose was infused (P &lt; 0.001). Associated with the elevations in plasma NE In the 2-mU insulin infusion were increases in pulse rate (P &lt; 0.05), pulse pressure (P &lt; 0.005), and pulse rate - systolic blood pressure product (P &lt; 0.01), and during the 5-mU insulin infusions there were increases in pulse pressure (P &lt; 0.001), mean arterial blood pressure (P &lt; 0.001), and pulse rate - systolic blood pressure product (P &lt; 0.001). Plasma NE did not change during the hyperglycemic glucose clamp nor during control tests, and pulse pressure in the hyperglycemic studies (P &lt; 0.005) was the only cardiovascular measurement increased by these two infusion protocols. The clearance of NE in three subjects was unaffected by the 2-mU insulin infusion. Thus, insulin infusion increases sympathetic nervous system activity in the absence of changes in blood glucose.
Calibration Transfer and Measurement Stability of Near-Infrared Spectrometers (1992)

Near-infrared (NIR) spectroscopy has been widely accepted as a quantitative technique in which multivariate calibration plays an important role. The application of NIR to process analysis, however, has been largely limited by a problem identified as calibration transfer, the attempt to transfer a well-established calibration model from one instrument (e.g., located in the central laboratory) to another instrument of the same type (e.g., located on an industrial process). A calibration transfer method called piecewise direct standardization (PDS) is applied to a set of gasoline samples measured on two different NIR spectrometers. On the basis of the measurement of a small set of transfer samples on both instruments, a structured transformation matrix can be determined and applied to transform spectra between two instruments, enabling the transfer of calibration models. The effect of spectrum preprocessing on standardization is studied with the use of a set of gasoline samples. In a separate study, the day-to-day instrument variation as observed from the change in the polystyrene spectrum is related to the prediction of moisture, oil, protein, and starch content in corn samples, and then the possibility of using such generic standards to replace real samples in a transfer set is explored. In all cases, a standard error for prediction comparable to full set cross-validation is obtained through standardization.
Advances in swell noise attenuation (2008)

Michel Schonewille, Alan Vigner and Alan Ryder of Petroleum Geo-Services describe a method for attenuating swell noise prevalent in towed streamer marine seismic which improves on standard FX filtering.
MMSE frequency combining for CI/DS-CDMA (2002)

In carrier interferometry (CI) DS-CDMA, novel chip shaping is used to introduce frequency diversity benefits to DS-CDMA systems. These frequency diversity benefits result in significant performance enhancements relative to the traditional DS-CDMA. In the CI/DS-CDMA receiver, two stages of combining are present: frequency combining to recreate chips, and chip combining to eliminate interfering users on the system. In the frequency combining, the combiner recreates chips while (1) minimizing interference and (2) creating optimal frequency diversity gain. The authors propose a novel MMSE frequency combiner for the CI/DS-CDMA receivers which achieves enhanced frequency combining. The performance results demonstrate that for P(/spl epsiv/)=10/sup -3/, a 5 dB performance improvement is achieved through use of the novel frequency combiner in CI/DS-CDMA receivers.
Mating refusal and its significance in females of the ladybird beetle, Harmonia axyridis (1988)

ABSTRACT. . Mating receptivity in females of the ladybird, Harmonia axyridis Pallas (Coleoptera: Coccinellidae), was studied with reference to internal and environmental conditions. Females sometimes reject copulation: they run away, or shake off the male and bend the abdomen upwards. Newly emerged females show a greater likelihood of accepting copulation with an advance in the stage of ovarian development, this being related to age. Females usually mate repeatedly, but frequently show refusal behaviour under unfavourable food conditions. Dissections reveal that females which accept copulation have a greater number of mature eggs in the ovary than do rejectors. Results also suggest that the food conditions are a major environmental factor, directly controlling mating receptivity.
Location optimization of electric vehicle charging stations: Based on cost model and genetic algorithm (2022)

Nowadays, the development of new energy science has gradually entered a good situation, and accordingly, electric vehicles have been recognized by people all over the world and rapidly popularized in various countries. However, the rapid growth of electric vehicles has caused a series of problems, such as insufficient number of charging stations, uneven distribution, and high cost, which are becoming increasingly serious. In order to solve the above problems, this paper takes Ireland as an example for research. Based on the collection of relevant information, this paper first tries to build a social total cost model, and calculates the total operating cost of charging stations under various distribution conditions. In this model, the total social cost is subdivided into comprehensive economic cost and environmental cost. Economic costs include construction costs and fees, while environmental costs include electricity consumption and carbon dioxide emissions. Secondly, this paper established a charging station location optimization model based on genetic algorithm, which simplified the Irish territory into a rectangle with a length of 350 km and a width of 200 km, subdivided it into small squares, and adjusted the correlation coefficient to meet the charging demand. This solution solves the minimization problem of operating cost under the constraints of depreciation period of charging station, power consumption per unit distance of charging station and vehicle charging probability. Finally, in order to determine the factors that may have a significant impact on the total cost of charging stations, we conducted sensitivity analysis and found that the total cost is very sensitive to the number of charging stations and the possibility of EV charging per day.
Intra-oral bonding of 4-META/MMA-TBB resin to vital human dentin. (1995)

Data were analyzed statistically, and no significant differences could be determined between third molars and first premolars, and in vivo and in vitro specimens. Further, tensile stress fractured specimens were examined under scanning and transmission electron microscopy. Widths (+/- 5 microns) of hybrid layers and impregnation of adhesive monomers into 10-3 solution demineralized vital human dentin substrates were essentially similar to those observed in extracted samples. The adhesive resin penetrated tubules to form resin tags, unimpeded by intra-tubular fluid under physiologic pressure in intra-orally prepared specimens. A hybrid layer formed on resin tags to seal against microleakage and pulpal attack by bacteria and their by-products. An acid-resistant hybrid layer was also observed in enamel. Finally, hydroxyapatite crystals that were encapsulated by polymerized 4-META/MMA-TBB resin was observed at the bases of resin-reinforced hybrid layers in the human dentin substrates. This observation is consistent with earlier findings and appears to be essential in maintaining durable dentin bonds.
Unitary space-time modulation via the Cayley transform (2003)

A method of generating good performing USTM constellations using the Cayley transform is proposed. The codes, which can be used for any number of transmit and receive antennas without channel knowledge, are designed based on an information-theoretic criterion, and lend themselves to polynomial-time near-maximum-likelihood decoding using the sphere decoding algorithm.
