Automated Chromium Plating Line for Gun Barrels (1979)

Abstract : This project was undertaken to establish a prototype automated chromium plating line for processing small caliber gun tubes. The automated line consists of a loading rack, electropolish tank, cold water rinse tanks, hot water rinse tank, chromium reverse etch tank and a chromium plating tank. The process involves automatic transference of racks containing the gun tubes to the various tanks in accordance to a programmed cycle. Parameters selected for the automated process were 2 asi and 4.5-minute process time to remove approximately 1.0 mil of stock during electropolish; and 2.5 asi and 50-minute plating time to deposit 1.0 mil of chromium plate. The feasibility of the automated process was shown and 12 out of 24 processed gun tubes were within the acceptable internal dimension range. Six additional gun tubes were within 0.1 to 0.2 mil of the acceptable bore diameter range. The quality of the chromium plate was satisfactory in all cases. The major difficulty in the automated process is the control of stock removal during the electropolish cycle. The elimination of the electropolish sequence is recommended with the use of rotary swaged gun tubes sized to pre-plating dimensions.
Smart enabling system for home automation (1991)

The author describes an enabling system called SMART HOUSE that provides the common resources needed for home automation in a multiproduct, multivendor environment. The system includes the following: a system controller, housewide wiring network, communications protocols, standard interfaces (outlet designs) for connecting other products, and basic user controls such as programmable wall switches and DTMF telephone. Providing complete home automation functionality depends on the addition of other products such as more complex user controls, appliances that include consumer electronics, and application-specific controllers for energy management, security, climate control, etc. These compatible appliances and controllers are equipped with proprietary communications circuits that permit them to communicate with the system controller and with each other. The author provides a concise technical description of the system, concentrating upon the control communications aspects, including system architecture, protocols, messaging, and logic structure.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Bidirectional recurrent convolutional networks for multi-frame super-resolution (2015)

Super resolving a low-resolution video is usually handled by either single-image super-resolution (SR) or multi-frame SR. Single-Image SR deals with each video frame independently, and ignores intrinsic temporal dependency of video frames which actually plays a very important role in video super-resolution. Multi-Frame SR generally extracts motion information, e.g., optical flow, to model the temporal dependency, which often shows high computational cost. Considering that recurrent neural networks (RNNs) can model long-term contextual information of temporal sequences well, we propose a bidirectional recurrent convolutional network for efficient multi-frame SR. Different from vanilla RNNs, 1) the commonly-used recurrent full connections are replaced with weight-sharing convolutional connections and 2) conditional convolutional connections from previous input layers to the current hidden layer are added for enhancing visual-temporal dependency modelling. With the powerful temporal dependency modelling, our model can super resolve videos with complex motions and achieve state-of-the-art performance. Due to the cheap convolution operations, our model has a low computational complexity and runs orders of magnitude faster than other multi-frame methods.

Human Parechovirus 3 and Neonatal Infections (2005)

A third serotype of human parechovirus (HPeV) has been recently isolated from stool specimens of a young Japanese child with transient paralysis. We report 3 additional cases of neonatal sepsis caused by HPeV-3 in the fall of 2001 in Canadian infants 7-27 days old. All children were hospitalized with high fever, erythematous rash, and tachypnea for a median of 5 days. The viruses isolated from nasopharyngeal aspirates grew slowly on tertiary monkey kidney cells and were successfully passaged on Vero cells. The predicted amino acid identity of the VP0-VP3-VP1 region of the three viruses was 74.6%-74.8%, 73.4%-73.6%, and 97.0%-97.1% when compared to HPeV-1, -2, and -3 prototype strains, respectively. Although different, our isolates were closely related; amino acid identity was 99.6%-100% for the last 3 proteins.
Molecular imaging of tumors and metastases using chemical exchange saturation transfer (CEST) MRI (2013)

The two glucose analogs 2-deoxy-D-glucose (2-DG) and 2-fluoro-2-deoxy-D-glucose (FDG) are preferentially taken up by cancer cells, undergo phosphorylation and accumulate in the cells. Owing to their exchangeable protons on their hydroxyl residues they exhibit significant chemical exchange saturation transfer (CEST) effect in MRI. Here we report CEST-MRI on mice bearing orthotopic mammary tumors injected with 2-DG or FDG. The tumor exhibited an enhanced CEST effect of up to 30% that persisted for over one hour. Thus 2-DG/FDG CEST MRI can replace PET/CT or PET/MRI for cancer research in laboratory animals, but also has the potential to be used in the clinic for the detection of tumors and metastases, distinguishing between malignant and benign tumors and monitoring tumor response to therapy as well as tumors metabolism noninvasively by using MRI, without the need for radio-labeled isotopes.
Application of zig-zag transformers in a three-wire three-phase dynamic sag corrector system (2004)

The industrial and commercial sector is increasingly dependent on sensitive electronic and power electronic process controls and experiences severe productivity losses from power quality events. The single phase DySC (dynamic sag corrector) provides protection against 92% of all power quality events, operating on a line-neutral basis. A three-phase DySC system consists of three single phase DySC modules connected one per phase, each of which use the neutral point as a reference for the voltage regulator as well as for maintaining charge on the DC bus capacitors. The zig-zag transformer is a very cost effective method of forming this neutral point. During an unsymmetrical sag event, there is a significant zero-sequence component at the input of the DySC, and the zig-zag transformer which has low impedance for zero-sequence components, will source most of the current to the rectifier. The voltage distortion at the formed neutral point and at the DySC input terminals depends on the zero sequence impedance of the transformer and the input current The harmonic content of the formed neutral voltage has to be limited to be within the bandwidth of the inverter so that it can be canceled out by the action of the inverter voltage regulator. A detailed mathematical analysis of the zig-zag transformer is performed to obtain its impedance characteristics. The variation of zero sequence impedance with the turns ratio is also studied for zig-zag transformers wound using E-cores and symmetric cores. Simulation results that show the behavior of the neutral point and the current sourced by the zig-zag in a three-wire DySC system are included along with experimental plots that validate the simulations. This study provides a detailed understanding of the zig-zag transformer impedance characteristics, its effects when applied in a three-wire DySC system and provides a method to specify and design the transformer.
Maintenance of protozoa and methanogens, and fiber digestion in rumen-simulating continuous culture. (1993)

An apparatus for rumen-simulating continuous culture (fermenter of 1.21 capacity) was constructed which was equipped with a dialyzing system, a sieving system, a pH controller, and a device for collecting methane. When dried grass and concentrate (each 10 g/l culture/d) were given twice daily with a small amount of clover juice and the fluid dilution rate was set at 1.5/d, oligotrich protozoa and Dasytricha were maintained at ca. 2 x 105/ml and 2 x 104/ml, respectively, at least for 10 d. On the other hand, Isotricha failed to grow and disappeared within 10 d. Care to keep anaerobiosis was needed for the maintenance of methanogens at a reasonable level. Irrespective of whether or not pH was controlled, there was no significant difference in the levels of protozoa and methane production under these conditions. However, when the concentrate was doubled (dried grass : concentrate =1: 2) without pH control, the drop in pH after feeding was large and protozoa were markedly decreased except for entodinia which are relatively resistant to low pH. Methane production and digestion of neutral detergent fiber (NDF) were also reduced with high concentrate. When pH was kept at 6.7 under these conditions, all groups of protozoa increased (total number, ca. 3 x 105/ml) except for Isotricha, and methane production and NDF digestion were also increased. These results suggest that the addition of an appropriate level of concentrate enhances fiber digestion, unless pH is dropped too much.
Identification of circulating fetal cell markers by microarray analysis (2012)

Of the 28 fetal marker candidate genes, five coded for proteins, which are located on the outer surface of the cell membrane and not expressed in blood. The protein product of these five genes, MMP14, MCAM, KCNQ4, CLDN6, and F3, may be used as markers for fetal cell enrichment.
Rescue of coagulation factor VII function by the U1+5A snRNA (2009)

Our previous studies with genomic minigenes have demonstrated that an engineered small nuclear RNA-U1 (U1+5a) partially rescued coagulation factor VII (FVII) mRNA processing impaired by the 9726+5G>A mutation. Here, to evaluate the U1+5a effects on FVII function, we devised a full-length FVII splicing-competent construct (pSCFVII-wt). This construct drove in COS-1 cells the synthesis of properly processed FVII transcripts and of secreted functional FVII (23 +/- 4 ng/mL), which were virtually undetectable upon introduction of the 9726+5G>A mutation (pSCFVII-9726+5a). Cotransfection of pSCFVII-9726+5a with pU1+5a resulted in a partial rescue of FVII splicing and protein biosynthesis. The level increase in medium was dose dependent and, with a molar excess (1.5x) of pU1+5a, reached 9.5% plus or minus 3.2% (5.0 +/- 2.8 ng/mL) of FVII-wt coagulant activity. These data provide the first insights into the U1-snRNA-mediated rescue of donor splice sites at protein level, thus further highlighting its therapeutic implications in bleeding disorders, which would benefit even from tiny increase of functional levels.
An analytical study on steady-state performance of an induction motor connected to unbalanced three-phase voltage (2002)

This paper presents an analytical study into the steady-state performance of a three-phase induction motor powered by unbalanced supply voltage. Positiveand negative-sequence equivalent circuits of the induction motor are used to ascertain phenomena caused by voltage unbalance such as line-current unbalance, derating, drop in machine efficiency, etc. This paper also proposes the ratio of motor positive- to negative-sequence impedance as an index that allows the sensitivity of line-current unbalance to voltage unbalance to be effectively evaluated. A numerical example is provided to show practical applications of the proposed analytical model.
Toward Improving <i>Caenorhabditis elegans</i> Phenome Mapping With an ORFeome-Based RNAi Library (2004)

The recently completed Caenorhabditis elegans genome sequence allows application of high-throughput (HT) approaches for phenotypic analyses using RNA interference (RNAi). As large phenotypic data sets become available, "phenoclustering" strategies can be used to begin understanding the complex molecular networks involved in development and other biological processes. The current HT-RNAi resources represent a great asset for phenotypic profiling but are limited by lack of flexibility. For instance, existing resources do not take advantage of the latest improvements in RNAi technology, such as inducible hairpin RNAi. Here we show that a C. elegans ORFeome resource, generated with the Gateway cloning system, can be used as a starting point to generate alternative HT-RNAi resources with enhanced flexibility. The versatility inherent to the Gateway system suggests that additional HT-RNAi libraries can now be readily generated to perform gene knockdowns under various conditions, increasing the possibilities for phenome mapping in C. elegans.
Clustering Images with Multinomial Mixture Models (2007)

In this paper, we propose a method for image clustering using multinomial mixture models. The mixture of multinomial distributions, often called multinomial mixture, is a probabilistic model mainly used for text mining. The effectiveness of multinomial distribution for text mining originates from the fact that words can be regarded as independently generated in the first approximation. In this paper, we apply multinomial distribution to image clustering. We regard each color as a word and color histograms as term frequency distributions. Recent work provides an evidence that color histograms are quite non-Gaussian. Therefore, we assume that there are no intrinsic dependencies between the frequencies of similar colors and adopt multinomial model. We can append other information, e.g. spatial information, because our model assumes no intrinsic dependencies among image features. Our experiment has compared multinomial mixture, Dirichlet mixture and k-means. Dirichlet mixture, a Bayesian version of multinomial mixture, is applied to image clustering for the first time as far as we know. The results of our evaluation experiment demonstrate that multinomial mixture gives higher accuracies than k-means. Further, Dirichlet mixture provides a result comparable to the best result of multinomial mixture.
Modeling and evaluating design alternatives for an on-line instrumentation system: a case study (1998)

This paper demonstrates the use of a model-based evaluation approach for instrumentation systems (ISs). The overall objective of this study is to provide early feedback to tool developers regarding IS overhead and performance; such feedback helps developers make appropriate design decisions about alternative system configurations and task scheduling policies. We consider three types of system architectures: network of workstations (NOW), symmetric multiprocessors (SMP), and massively parallel processing (MPP) systems. We develop a Resource OCCupancy (ROCC) model for an on-line IS for an existing tool and parameterize it for an IBM SP-2 platform. This model is simulated to answer several "what if" questions regarding two policies to schedule instrumentation data forwarding: collect-and-forward (CF) and batch-and-forward (BF). In addition, this study investigates two alternatives for forwarding the instrumentation data: direct and binary tree forwarding for an MPP system. Simulation results indicate that the BF policy can significantly reduce the overhead and that the tree forwarding configuration exhibits desirable scalability characteristics for MPP systems. Initial measurement-based testing results indicate more than 60 percent reduction in the direct IS overhead when the BF policy was added to Paradyn parallel performance measurement tool.
Comparative study of long, segmented, filamentous organisms in chickens and mice. (1992)

No transmission of long, segmented, filamentous organisms (LSFO) from a laboratory mouse strain (Mus musculus) to a domestic broiler chicken strain (Gallus domesticus) occurred by oral dosing with mouse mucosal and fecal preparations, even in hydrocortisone-treated chicks. Transmission of chicken LSFO to laboratory mice was attempted, but the results were confounded by the mice having been already infected with LSFO. However, the morphologic characteristics of the LSFO in the dosed mice suggested that transmission of chick LSFO did not occur. Mouse LSFO, as detected in carbol thionin-stained mucosal smears, are generally wider, longer, and have slightly different morphologic characteristics than chicken LSFO. The results of these studies suggest that the LSFO in mice and chickens may be two distinct species.
Input-Series Two-Stage DC-DC Converter with Inductor Coupling (2007)

This paper presents an input-series and inductor- coupled two-stage scheme to DC-DC converter. Discussions of the circuit in Discontinuous Conduction Mode (DCM) are provided both when inversely coupled interleaving and when directly coupled without phase shift. According to detailed analysis, inverse coupling is more beneficial for current ripple reduction when the windings are not so tightly coupled. The reason to avoid tight coupling is that current spikes and resonance due to voltage mismatch can be suppressed, since the two coupled windings have a large leakage inductance. A prototype with 500-700 V input and 5 V/30 A output is built. Experimental results verify the principle and performance of the proposed approach.
Influence of different intragastric stimuli on triggering of transient lower oesophageal sphincter relaxation in the dog (1999)

Gastro-oesophageal reflux in the dog is mainly caused by transient lower oesophageal sphincter relaxation (TLOSR), the major stimulus for which is distension of the stomach. The possibility that liquid and/or acid sensors in the proximal stomach reduce the incidence and/or shorten the duration of TLOSR was addressed in the present study. Manometric recordings of the pharynx, oesophagus, lower oesophageal sphincter and stomach were made in awake dogs equipped with an oesophagostomy. TLOSRs were induced by insufflation of air or infusion of liquid nutrients with varying pH. Intragastric distension with air provoked TLOSRs with a significantly shorter duration than those seen after distension with liquid (4.3 +/- 0.5 vs 9.6 +/- 0.3 sec; P < 0.05). There were fewer TLOSRs at high intragastric pH (pH 5.0: 3.1 +/- 0.5/90 min) than at low pH (pH 1.5: 5.5 +/- 0.9/90 min, P < 0.05). Successfully propagated peristalsis following a TLOSR was more common after stimulation with liquid than with air. It can be concluded that there are H(+)-sensing mechanisms in the stomach which stimulate triggering of TLOSR. In addition, the reduced duration of TLOSR during air insufflation shows that the physical state of the distending stimulus can affect the patterning of TLOSR.

Shaker Simulation of Random Vibration with a High Kurtosis Value (1997)

This paper presents a vibration test technique for extending the tails of amplitude probability distribution beyond the Gaussian values as is characteristic for vibration of ground vehicles on a rough road or terrain. The method proposed uses the commonly accepted approach of applying pseudorandom excitation in the form of a Fourier expansion. The procedure described in this paper can be implemented by updating currently available digital vibration controllers. The solution for amplitude domain fitting is based on an analytical expression derived for the kurtosis parameter of the polyharmonic process in terms of amplitudes and phase angles for any number of harmonic components. The results of theoretical analysis are embodied in software subjected to verification in computer and experimental tests. Even with additional kurtosis control, the closeness of the generated and desired spectra is the same as for the Gaussian simulation of power spectral density. Hence, this new technique for amplitude domain matching is not accompanied by the deterioration of ordinary test capabilities in the frequency domain.
Al<sub>2</sub>O<sub>3</sub>:Cr<sup>3+</sup> Nanotubes Synthesized via Homogenization Precipitation Followed by Heat Treatment (2006)

Cr3+-doped NH4Al(OH)2CO3 nanotubes, templated by surfactant assemblies, were successfully synthesized via the homogenization precipitation method, and various crystallographic phase Al2O3:Cr3+ nanotubes were also obtained by postannealing at different temperatures. The characteristic R1, R2 doublet line transitions of ruby can be observed in the high crystalline alpha-Al2O3 nanotubes calcined at temperatures higher than 1200 degrees C. The results also indicate that the formation mechanism of the tubular nanostructures should result from the self-rolling action of layered compound NH4Al(OH)2CO3 under the assistance of the surfactant soft-template. The convenient synthetic procedure, excellent reproducibility, clean reactions, high yield, and fine quality of products in this work make the present route attractive and significant. Aluminum oxide nanotubes with high specific surface area could be used as fabricating nanosized optical devices doped with different elements and stable catalyst supports of metal clusters.
De Novo Design and Synthesis of Ultra-Short Peptidomimetic Antibiotics Having Dual Antimicrobial and Anti-Inflammatory Activities (2013)

The combination of the ultra-short size, high-prokaryotic selectivity, potent anti-MRSA activity, anti-inflammatory activity, and proteolytic resistance of the designed HDAMP-1, -3, -5, and -6 makes these molecules promising candidates for future antimicrobial therapeutics.
Counterpoint: Vancomycin and Staphylococcus aureus--An Antibiotic Enters Obsolescence (2007)

The efficacy of vancomycin for the treatment of patients with infections due to Staphylococcus aureus is impaired by its poor tissue penetration and by its relatively weak antibacterial activity--an activity that is declining as S. aureus evolves. Neither dose escalation nor use of vancomycin in combination with other antibiotics that have antistaphylcoccal activity has been demonstrated to safely enhance its therapeutic efficacy. Although no clinical trials suggest superiority of vancomycin over any comparator, some have provided evidence of its inferiority. Strong consideration should be given to the use of alternative agents in the treatment of serious S. aureus infections.
