Isolation of Salmonellae by Selective Motility Systems (1965)

Salmonellae were isolated from naturally infected swine and human feces by means of selective migration through semisolid enrichment (SM) media in modified "U" tubes. Comparative studies showed that recovery of Salmonella by SM techniques was equal or superior to that of standard procedures employed in two routine diagnostic laboratories. Primary Salmonella isolations from SM enrichment were relatively free from normal fecal bacteria and often pure. The SM method required only 15% of the media and correspondingly less time and skill than the usual methods for isolating Salmonella.
A quadrature lowpass birdcage coil for a vertical low field MRI scanner (2004)

Abstract Birdcage coils are widely used in magnetic resonance imaging (MRI) applications for their ability to operate in transmit/receive mode with high signal‐to‐noise ratio and wide homogeneous field. When used in horizontal bore MRI systems, the birdcage coil is able to produce circular polarized field using quadrature excitation, thus reaching SNR improvement of √ 2 as maximum value. In a previous article, the highpass birdcage coil was employed in a vertical bore MRI scanner by combining the sinusoidal and the end‐ring resonant modes. In this article, we investigated the lowpass birdcage coil configuration to operate with a vertical bore MRI system, producing two B 1 fields components perpendicular to the vertical B 0 field. Its implementation is convenient because it requires one‐half capacitors with respect to the highpass design. Moreover, at low field, the high near‐electric field losses, which are the main disadvantage of the lowpass design, can be neglected. Experiments performed on a quadrature birdcage coil prototype mounted on an open MRI scanner showed that SNR and homogeneity degree increase with respect to the linear birdcage. © 2004 Wiley Periodicals, Inc.

OffsetNet: Deep Learning for Localization in the Lung using Rendered Images (2019)

Navigating surgical tools in the dynamic and tortuous anatomy of the lung's airways requires accurate, real-time localization of the tools with respect to the preoperative scan of the anatomy. Such localization can inform human operators or enable closed-loop control by autonomous agents, which would require accuracy not yet reported in the literature. In this paper, we introduce a deep learning architecture, called OffsetNet, to accurately localize a bronchoscope in the lung in real-time. After training on only 30 minutes of recorded camera images in conserved regions of a lung phantom, OffsetNet tracks the bronchoscope's motion on a held-out recording through these same regions at an update rate of 47 Hz and an average position error of 1.4 mm. Because this model performs poorly in less conserved regions, we augment the training dataset with simulated images from these regions. To bridge the gap between camera and simulated domains, we implement domain randomization and a generative adversarial network (GAN). After training on simulated images, OffsetNet tracks the bronchoscope's motion in less conserved regions at an average position error of 2.4 mm, which meets conservative thresholds required for successful tracking.
Synthesis and properties of new polybenzimidazoles and <i>N</i>‐phenyl polybenzimidazoles with flexibilizing spacers on the polymer backbone (1987)

Abstract Several new polybenzimidazoles (PBIs) and N ‐phenyl PBIs were synthesized by high temperature solution polycondensation techniques. Three different tetramine hydrochlorides and one N ‐phenyl tetramine hydrochloride were condensed independently with p ‐phenylenedioxydiacetic acid (PDDA), 2,2′‐[isopropylidene bis( p ‐phenyleneoxy)] diacetic acid (bisacid A 2 ) and 2,2′‐[sulfonyl bis( p ‐phenyleneoxy)] diacetic acid (bisacid S) in polyphosphoric acid (PPA) at high temperatures. The polymers were obtained in 55–65% yield with inherent viscosities in the range 0.58–0.96 dL/g. Four model benzimidazoles (MBI) were also synthesized to confirm the formation of polybenzimidazoles. The PBIs and MBIs were characterized by infrared spectroscopy and elemental analysis. The properties of the polymers such as solubility, density, crystallinity, and thermal, thermoxidative, and isothermal stabilities were studied.
Nanolipodendrosome-loaded glatiramer acetate and myogenic differentiation 1 as augmentation therapeutic strategy approaches in muscular dystrophy (2013)

The loaded lipodendrimer nanocarrier with the candidate drug, in comparison with the nandrolone control drug, caused a significant increase in muscular mass, a reduction in CD4+/CD8+ inflammation markers, and no significant toxicity was observed. The results support the hypothesis that the nanolipodendrimer containing the two candidate drugs will probably be an efficient means to ameliorate muscular degeneration, and warrants further investigation.
A Kohonen SOM based, machine health monitoring system which enables diagnosis of faults not seen in the training set (2005)

A unique system is described which uses Kohonen self organising networks and an expert system to enable predictive maintenance of rotational machinery. The system can be trained on vibration data recorded from a machine operating at full health throughout its normal operating envelope. Once trained, the system can monitor the machines vibrations detecting and diagnosing fault conditions. In this way, faults are diagnosed which were not included in the training set, thus overcoming the problems involved with collecting fault data.
Wavelet-based ECG compression using dynamic vector quantization with tree codevectors in single codebook (2002)

In this paper, we propose a novel vector quantizer (VQ) in the wavelet domain for the compression of electrocardiogram (ECG) signals. A vector called tree vector (TV) is formed first in a novel structure, where wavelet transformed (WT) coefficients in the vector are arranged in the order of a hierarchical tree. Then, the TVs extracted from various WT subbands are collected in one single codebook. This feature is an advantage over traditional WT-VQ methods, where multiple codebooks are needed and are usually designed separately because numerical ranges of coefficient values in various WT subbands are quite different. Finally, a distortion-constrained codebook replenishment mechanism is incorporated into the VQ, where codevectors can be updated dynamically, to guarantee reliable quality of reconstructed ECG waveforms. With the proposed approach both visual quality and the objective quality in terms of the percent of root-mean-square difference (PRD) are excellent even in a very low bit rate. For the entire 48 records of Lead II ECG data in the MIT/BIH database, an average PRD of 7.3% at 146 b/s is obtained. For the same test data under consideration, the proposed method outperforms many recently published ones, including the best one known as the set partitioning in hierarchical trees.
UHV-REM Study of Changes in the Step Structures on Clean (100) Silicon Surfaces by Annealing (1987)

Changes in the step structures on clean (100) silicon surfaces during annealing were observed by in situ ultra high vacuum reflection electron microscopy. After quenching from 1200°C, at about 800°C almost the entire surface was covered with periodic arrays of 2×1 and 1×2 reconstructed domains bounded by monolayer high steps. One type of reconstructed domain, with dimers parallel to the average tilt axis [011̄], grew over the other above 900°C. The terrace size became as large as a few microns. However, a small number of periodic arrays of reconstructed domains remained stable at above 1000°C even under apparent surface evaporation.
Resumption of Athletic Activity in Patients Who Underwent Conser Ative Treatment of Torn Lateral Ligaments. (1995)

A freshly torn lateral ligament of the ankle often requires surgical therapy. Operative treatment is usually selected if radiographic examination performed with the heel held under adduction stress reveals a tilting angle (TT) of the talus greater than 10 degrees.This study compared the results of surgical and conservative therapies and we hoped that our findings would help to clarify the limitations of conservative therapy. Subjects included those whose talus was tilted over 10 degrees with the heel fully inverted. Torn lateral ligaments were conservatively treated in 214 patients at our hospital. The mean difference in TT between the right and left ankles was 7.96 degrees in these patients. The difference in treatment results between patients with a TT of over 10 degrees and those under 10 degrees was statistically significant. The difference in treat ment results between patients undergoing surgical and conservative therapies in patients with a TT of less than 10 degrees was not statistically significant.

A Study of Trimethylsilane (3MS) and Tetramethylsilane (4MS) Based α-SiCN:H/α-SiCO:H Diffusion Barrier Films (2012)

Amorphous nitrogen-doped silicon carbide (α-SiCN:H) films have been used as a Cu penetration diffusion barrier and interconnect etch stop layer in the below 90-nanometer ultra-large scale integration (ULSI) manufacturing technology. In this study, the etching stop layers were deposited by using trimethylsilane (3MS) or tetramethylsilane (4MS) with ammonia by plasma-enhanced chemical vapor deposition (PECVD) followed by a procedure for tetra-ethoxyl silane (TEOS) oxide. The depth profile of Cu distribution examined by second ion mass spectroscopy (SIMs) showed that 3MS α-SiCN:H exhibited a better barrier performance than the 4MS film, which was revealed by the Cu signal. The FTIR spectra also showed the intensity of Si-CH₃ stretch mode in the α-SiCN:H film deposited by 3MS was higher than that deposited by 4MS. A novel multi structure of oxygen-doped silicon carbide (SiC:O) substituted TEOS oxide capped on 4MS α-SiC:N film was also examined. In addition to this, the new multi etch stop layers can be deposited together with the same tool which can thus eliminate the effect of the vacuum break and accompanying environmental contamination.
Development and application of a designer oriented cyclic simulator (1976)

Because of the increasing complexity of the role of the design engineer, in the design of digital systems, the need has arisen for a behavioral modeling technique which can be accurately controlled by the designer, with minimal effort, while remaining relatively error free. Explored here will be a technique for behavioral modeling of digital system designs which is in variance with the more traditional approaches.
Arginase Inhibition Reverses Monocrotaline-Induced Pulmonary Hypertension (2017)

Pulmonary hypertension (PH) is a heterogeneous disorder associated with a poor prognosis. Thus, the development of novel treatment strategies is of great interest. The enzyme arginase (Arg) is emerging as important player in PH development. The aim of the current study was to determine the expression of ArgI and ArgII as well as the effects of Arg inhibition in a rat model of PH. PH was induced in 35 Sprague-Dawley rats by monocrotaline (MCT, 60 mg/kg as single-dose). There were three experimental groups: sham-treated controls (control group, <i>n</i> = 11), MCT-induced PH (MCT group, <i>n</i> = 11) and MCT-induced PH treated with the Arg inhibitor Nω-hydroxy-nor-l-arginine (nor-NOHA; MCT/NorNoha group, <i>n</i> = 13). ArgI and ArgII expression was determined by immunohistochemistry and Western blot. Right ventricular systolic pressure (RVPsys) was measured and lung tissue remodeling was determined. Induction of PH resulted in an increase in RVPsys (81 ± 16 mmHg) compared to the control group (41 ± 15 mmHg, <i>p</i> = 0.002) accompanied by a significant elevation of histological sum-score (8.2 ± 2.4 in the MCT compared to 1.6 ± 1.6 in the control group, <i>p</i> < 0.001). Both, ArgI and ArgII were relevantly expressed in lung tissue and there was a significant increase in the MCT compared to the control group (<i>p</i> < 0.01). Arg inhibition resulted in a significant reduction of RVPsys to 52 ± 19 mmHg (<i>p</i> = 0.006) and histological sum-score to 5.8 ± 1.4 compared to the MCT group (<i>p</i> = 0.022). PH leads to increased expression of Arg. Arg inhibition leads to reduction of RVPsys and diminished lung tissue remodeling and therefore represents a potential treatment strategy in PH.
Big Data: Astronomical or Genomical? (2015)

Genomics is a Big Data science and is going to get much bigger, very soon, but it is not known whether the needs of genomics will exceed other Big Data domains. Projecting to the year 2025, we compared genomics with three other major generators of Big Data: astronomy, YouTube, and Twitter. Our estimates show that genomics is a "four-headed beast"--it is either on par with or the most demanding of the domains analyzed here in terms of data acquisition, storage, distribution, and analysis. We discuss aspects of new technologies that will need to be developed to rise up and meet the computational challenges that genomics poses for the near future. Now is the time for concerted, community-wide planning for the "genomical" challenges of the next decade.
A reconfigurable oscillator topology for dual-band operation (2005)

An area-efficient oscillator topology for dual-band applications is proposed. The oscillator can be configured to operate in one of two states with distinct oscillation frequencies, and does not require a frequency divider for dual-band operation. A wide separation between the output frequencies can be achieved. The area and power requirements and phase noise performance are expected to be almost identical to those of a single-band NMOS cross-coupled oscillator.
Integrating Second Life into a Chinese language teacher training program: A pilot study (2010)

Second Life (SL), a 3-D Multi-User Virtual Environment, has been found beneficial to foreign language education because of its immersive and interactive environments. This cross-continental study explored feasibilities of using Second Life to provide field experiences to pre-service Mandarin teachers in a program of Teaching Chinese as a Foreign Language in Taiwan. This study also investigated pre-service teachers‘ insights of teaching Chinese in such a virtual environment, as well as the difficulties these teachers encountered when integrating Second Life in teaching Chinese. The study found that the more teaching experience the pre-service teachers gained in teaching Chinese in Second Life, the more positive an attitude they would develop toward adopting Second Life in teaching Chinese virtually, and in contrast, the less frustrations they would have for technical challenges when teaching in Second Life.
Fatty acid biosynthesis. II. Fate of fatty acids synthesised by subcellular fractions of lactating-rabbit mammary gland. (1966)

Abstract 1. 1. Subcellular fractions of lactating-rabbit mammary gland have been incubated under optimum conditions for fatty acid synthesis and the nature and subcellular site of the products examined. 2. 2. When “microsomal + particle-free supernatant” fractions were incubated with labelled acetate, a large proportion of the radioactivity was associated with newly synthesised glycerides in the microsomal fraction. Radioactive unesterified fatty acids were found to be located in the particle-free supernatant. 3. 3. Particle-free supernatant fractions alone synthesised exclusively unesterified fatty acids. 4. 4. Though both the mitochondrial and microsomal fractions bind synthesised fatty acids, the microsomal fraction stimulated both fatty acid and glyceride synthesis to a greater extent than did the mitochondrial fraction. 5. 5. It has been shown that whereas certain free fatty acids inhibited fatty acid synthesis, the corresponding glycerides had little inhibitive effect. 6. 6. The results support the view that the microsomal stimulation of fatty acid synthesis is due, at least in part, to a relief of the feedback inhibition excercised by the products of fatty acid synthesis.
Sensor fusion for precise autonomous vehicle navigation in outdoor semi-structured environments (2005)

This paper presents a guidance system for autonomous vehicles navigation in semi-structured outdoor environments. It integrates redundant encoders data and absolute positioning data provided by landmarks and artificial beacons. Natural features are localized using a laser range sensor, and magnetic sensing rulers were developed to detect magnetic markers buried in the ground. In the first fusion stage, data from four wheel encoders and one steering encoder are fused by means of an EKF, providing robust odometric information, namely in face of undesirable effects of wheels slippage. Next, a second fusion stage is processed for integrating odometric and absolute positioning data. Simulation and real experiments using a four-wheels actuated electrical vehicle are presented.
Thymus‐independent class switch recombination is affected by APRIL (2008)

The tumour necrosis factor (TNF) family member a proliferation-inducing ligand (APRIL) is implicated in various B-cell processes, such as class switch recombination, plasma cell differentiation and plasma cell survival. This was suggested from initial studies analysing B-cell responses in APRIL-deficient and transgenic mice, and mice deficient for the TNF receptors of APRIL, transmembrane activator and CAML interactor (TACI) and B-cell maturation antigen. Here, we present additional evidence for the importance of APRIL in thymus-independent (TI) B-cell responses, using APRIL-deficient and transgenic mice. APRIL-deficient mice show an impaired immunoglobulin A (IgA) response towards TI B-cell antigens, whereas APRIL transgenic mice show exaggerated TI B-cell responses. Moreover, antibody titres to TI antigens were sustained in APRIL transgenic mice for a long time and even increased up to 75 days in the case of IgA against 4-hydroxy-nitrophenacetyl-lipopolysaccharide.
Review—Critical Considerations of High Quality Graphene Synthesized by Plasma-Enhanced Chemical Vapor Deposition for Electronic and Energy Storage Devices (2017)

Graphene is a promising electrode material not only due to its intrinsic properties like good electrical conductivity, high mechanical strength and high chemical stability, but also because of its high theoretical surface area of 2630 m2 g−1. In this report, the effect of CVD parameters to the growth of high quality graphene on metal substrates by using plasma enhanced chemical vapor deposition (PECVD) was extensively studied. Interestingly, synthesizing high quality graphene by PECVD technique is not only depending on the CVD parameters, but also depending on the catalysts and its plasma sources. It was found that Ni and Cu are the most favored metal catalysts for PECVD graphene growth. With high solubility of carbon (> 0.1 at. %), Ni effectively promote the growth of multilayer graphene by PECVD. However, large-area synthesis has made relatively inexpensive Cu as one of the most attractive substrates for monolayer graphene growth. Further details on the potential use of different transition metal catalysts in synthesizing graphene and consequently the specific usage of graphene based devices are discussed in this report.
