A New Protocol to Detect Multiple Foodborne Pathogens with PCR Dipstick DNA Chromatography after a Six-Hour Enrichment Culture in a Broad-Range Food Pathogen Enrichment Broth (2013)

A quick foodborne pathogen screening method after six-hour enrichment culture with a broad-range food pathogen enrichment broth is described. Pathogenic factors of Salmonella enterica, Shigella spp., enteroinvasive Escherichia coli, and enterohemorrhagic E. coli are amplified with a cocktail primer and rapid polymerase chain reaction (PCR), which finishes amplification in 30 min. The PCR amplicon was differentiated with a dipstick DNA chromatography assay in 5-10 min. Starting from a four- to six-hour enrichment culture, this assay was finished within 45 min. Detection sensitivity of this protocol was less than 2.5 CFU/25 g for S. enterica and 3.3 CFU/25 g for enterohemorrhagic E. coli in spiked ground meat experiments.
LII. Experiments on two-dimensional supersonic flow in corners and over concave surfaces (1952)

Summary Two simple cases of two-dimensional supersonic flow were investigated by schlieren photography, viz. the flow in two consecutive corners and the flow over a circular-arc profile concave to the stream. The flows were photographed for smooth and rough surfaces of the models, i.e. with laminar and turbulent boundary layers, and the observed flow-patterns are compared with those predicted by inviscid theory. The flow with a turbulent boundary layer was in good agreement with inviscid theory outside the boundary layer, whereas the laminar boundary layer separated and a shock wave originated at the point of separation, in both cases the agreement was good at points far from the surface.
Coherent Object Detection with 3D Geometric Context from a Single Image (2013)

Objects in a real world image cannot have arbitrary appearance, sizes and locations due to geometric constraints in 3D space. Such a 3D geometric context plays an important role in resolving visual ambiguities and achieving coherent object detection. In this paper, we develop a RANSAC-CRF framework to detect objects that are geometrically coherent in the 3D world. Different from existing methods, we propose a novel generalized RANSAC algorithm to generate global 3D geometry hypotheses from local entities such that outlier suppression and noise reduction is achieved simultaneously. In addition, we evaluate those hypotheses using a CRF which considers both the compatibility of individual objects under global 3D geometric context and the compatibility between adjacent objects under local 3D geometric context. Experiment results show that our approach compares favorably with the state of the art.
A New Type of Material for the Recovery of Hydrogen from Gas Mixtures (2004)

Gaswerke en miniature: Durch Sublimation gezüchtete p-tert-Butylcalix[4]aren-Kristalle verfügen über große interstitielle Cavitäten. Obwohl diese Festkörper nichtporös sind, können sie praktisch unter Standardbedingungen Gase wie O2, N2 und CO2 absorbieren und speichern. Da H2 nicht eingelagert wird, bietet sich das Material für die Trennung von H2 aus Gasgemischen an. Beim Evakuieren oder Eintauchen der Kristalle in Nitrobenzol (siehe Bild) werden die Gase wieder freigesetzt.

Solid solution InxGa1−x AsySbzP1−y−z : A new material for infrared optoelectronics. I. Thermodynamic analysis of the conditions for obtaining solid solutions, isoperiodic to InAs and GaSb substrates, by liquid-phase epitaxy (1997)

The diagrams of melt-solid solution (fusibility curves) and solid solution (I)-solid solution (II) (surfaces of spinodal decomposition of solid solutions) phase equilibria in the five-component system In-Ga-As-Sb-P (the solid solutions are isoperiodic to the GaSb and InAs substrates) are calculated. The concentration ranges of the isovalent substitution solid solutions InxGa1−x AsySbzP1−y−z , which are accessible for synthesis by liquid-phase epitaxy, are calculated.
Resonances in four-wave mixing penalties in long-haul WDM transmission links (2002)

We show computationally and experimentally that resonances in the received signal variance can occur in WDM transmission systems as channel separation is varied. The resonances are related to periodic gain along the optical path and distribution in dispersion. To our knowledge this is the fist measurement of this effect in a long-haul transmission experiment.
Phage T7 Gp2 inhibition of <i>Escherichia coli</i> RNA polymerase involves misappropriation of σ <sup>70</sup> domain 1.1 (2013)

Bacteriophage T7 encodes an essential inhibitor of the Escherichia coli host RNA polymerase (RNAP), the product of gene 2 (Gp2). We determined a series of X-ray crystal structures of E. coli RNAP holoenzyme with or without Gp2. The results define the structure and location of the RNAP σ(70) subunit domain 1.1(σ(1.1)(70)) inside the RNAP active site channel, where it must be displaced by the DNA upon formation of the open promoter complex. The structures and associated data, combined with previous results, allow for a complete delineation of the mechanism for Gp2 inhibition of E. coli RNAP. In the primary inhibition mechanism, Gp2 forms a protein-protein interaction with σ(1.1)(70), preventing the normal egress of σ(1.1)(70) from the RNAP active site channel. Gp2 thus misappropriates a domain of the RNAP holoenzyme, σ(1.1)(70), to inhibit the function of the enzyme.

Two-dimensional simulations are conducted to assess the effects of disturbance on detonation initiation. A disturbance can induce a complex shock wave interaction which induces a local explosion. Disturbances can thus be used to promote detonation initiation.
Status of obstetric epidural analgesia services in Hong Kong public hospitals: postal questionnaire survey. (2003)

Although there has been progress and improvement in the provision of obstetric epidural analgesia services in our public hospitals, the rate is still relatively low and the provision of services after hours is limited. Further progress will likely be hindered by current or future cutbacks in public hospital budgets.
Hyperosmolarity Does Not Contribute to Transient Radicular Irritation After Spinal Anesthesia With Hyperbaric 5% Lidocaine (1995)

The results suggest that transient radicular irritation did not result from the marked hyperosmolarity of the hyperbaric 5% lidocaine. However, because lidocaine and bupivacaine were not administered at equipotent dosages, the relative potential for both drugs to induce transient radicular irritation remains to be determined.
Real-Time Human Posture Reconstruction in Wireless Smart Camera Networks (2008)

While providing a variety of intriguing application opportunities, a vision sensor network poses three key challenges. High computation capacity is required for early vision functions to enable real-time performance. Wireless links limit image transmission in the network due to both bandwidth and energy concerns. Last but not least, there is a lack of established vision-based fusion mechanisms when a network of cameras is available. In this paper a distributed vision processing implementation of human pose interpretation on a wireless smart camera network is presented. The motivation for employing distributed processing is to both achieve real-time vision and provide scalability for developing more complex vision algorithms. The distributed processing operation includes two levels. One is that each smart camera processes its local vision data, achieving spatial parallelism. The other is that different functionalities of the whole line of vision processing are assigned to early vision and object-level processors, achieving functional parallelism based on the processor capabilities. Aiming for low power consumption and high image processing performance, the wireless smart camera is based on an SIMD (single-instruction multiple-data) video analysis processor, an 8051 micro-controller as the local host, and wireless communication through the IEEE 802.15.4 standard. The vision algorithm implements 3D human pose reconstruction. From the live image data from the sensor the smart camera acquires critical joints of the subject in the scene through local processing. The results obtained by multiple smart cameras are then transmitted through the wireless channel to a central PC where the 3D pose is recovered and demonstrated in a virtual reality gaming application. The system operates in real time with a 30 frames/sec rate.
Automatic Detection of Reference Face and The Recognition of Transition of Facial Expressions (2001)

Several researchers have recently attempted automatic recognition and tracking of the facial expressions in video frames. However, it is very hard to detect a neutral face because the distinction between facial movement and head movement is difficult to make. To solve this distinction problem, the head position was initialized using the central point of each eye and the tip of the nose. The transition of facial expressions can be recognized by means of detecting the reference face (neutral face) and the recognition algorithm constructed to the expert system.
Size-Dependent Superparamagnetic Properties of Mn Spinel Ferrite Nanoparticles Synthesized from Reverse Micelles (2001)

MnFe2O4 nanoparticles in a size range of 4−14 nm have been synthesized from water-in-toluene reverse micelles by using sodium dodecylbenzenesulfonate (NaDBS) as surfactant. The blocking temperature, saturation magnetization, and coercivity of the nanoparticles are clearly size-dependent. The blocking temperature increases from 20 to 250 K when the mean size of the nanoparticles increases from 4.4 to 13.5 nm. The coercivity at 20 K increases from 30 to 300 Oe with increasing nanoparticle size. The field-dependent magnetization hysteresis disappears above the blocking temperature. Due to high saturation field, the saturation magnetization of the nanoparticles has been obtained by the extrapolation of the magnetization vs 1/H plot to 1/H = 0. The saturation magnetization decreases with decreasing nanoparticle size. The high saturation field and the size-dependent saturation magnetization suggest the existence of a magnetically inactive layer on MnFe2O4 nanoparticles. The linear fitting of the saturation magnetization vs 1/d plot gives the thickness of this inactive layer as 0.45 nm.

Ketogenic diet modifies the gut microbiota in a murine model of autism spectrum disorder (2016)

Results indicate that consumption of a KD likely triggers reductions in total gut microbial counts and compositional remodeling in the BTBR mouse. These findings may explain, in part, the ability of a KD to mitigate some of the neurological symptoms associated with ASD in an animal model.
Population Snapshot of Emergent<i>Streptococcus pneumoniae</i>Serotype 19A in the United States, 2005 (2008)

PCV7 ineffectiveness against serotype 19A, antibiotic resistance, clonal expansion and emergence, and capsular switching have contributed to the genetic diversity of 19A and to its emergence as the predominant invasive pneumococcal serotype in the United States.
Optical tracking of contrast medium bolus to optimize bolus shape and timing in dynamic computed tomography (2012)

One of the biggest challenges in dynamic contrast-enhanced CT is the optimal synchronization of scan start and duration with contrast medium administration in order to optimize image contrast and to reduce the amount of contrast medium. We present a new optically based approach, which was developed to investigate and optimize bolus timing and shape. The time-concentration curve of an intravenously injected test bolus of a dye is measured in peripheral vessels with an optical sensor prior to the diagnostic CT scan. The curves can be used to assess bolus shapes as a function of injection protocols and to determine contrast medium arrival times. Preliminary results for phantom and animal experiments showed the expected linear behavior between dye concentration and absorption. The kinetics of the dye was compared to iodinated contrast medium and was found to be in good agreement. The contrast enhancement curves were reliably detected in three mice with individual bolus shapes and delay times of 2.1, 3.5 and 6.1 s, respectively. The optical sensor appears to be a promising approach to optimize injection protocols and contrast enhancement timing and is applicable to all modalities without implying any additional radiation dose. Clinical tests are still necessary.
Real-Time Pupil-Tracking embedded-system based on neural networks (2017)

This paper proposes a low-cost video-based Real-Time Pupil-Tracking embedded system which will allow people with reduced mobility to control a wheelchair through their eyes. The main aspect of the method is its capacity to be implemented in a portable computing system, reduced both in computing power and in RAM memory. The Pupil-Tracking system is based on Feedforward Neural Networks-using offline training-, and in the “dark pupil effect”. The performance of the method was validated using an own database, built under different ambient lighting conditions.

Studies on an AC/DC Combination Discharge Mode for NOx Treatment (2002)

A simplified AC/DC combination discharge mode for investigation of NOx treatment was carried out in this paper. A positive streamer corona discharge (DC) combined with a barrier discharge (AC) by an AC/DC conversion circuit. In such system, the sample gas (NO/N2) is treated by barrier and streamer discharge serially. The NO removal rate of the system was 52%, which was 12.3% and 27.7% when only barrier or streamer discharge was used respectively.
Chemical engineering aspects of reactive dyeing (1985)

Abstract The process of dyeing with reactive dyes was formulated on the basis of diffusion of dye species in the pores of polymer phase accompanied by fixation reaction with fiber substrate on the pore wall incorporating hydrolysis of dye species. The effect of the hydrolysis on the fractional fixation was numerically analyzed under various levels of bath ratio and degree of mixing in the dyebath. The simulation model was presented to yield the unlevelness arisen from lack of uniformity of degree of mixing in the dyebath.
Advanced compounding: Extrusion of polypropylene nanocomposites using the melt pump (2009)

Abstract A melt pump was assembled into the compounding line to ensure both sufficient time for diffusion process of polymer chains into the silicate gallery and sufficient mechanical shear energy for exfoliation of clay layers. The melt pump in front of the open co‐rotating twin‐screw extruder controls the throughput rate and the residence time, whereas the screw speed and screw geometry in the extruder determine the mechanical shear energy applied on the compound. Due to melt pump employment, the melt in metering zone can be accumulated, which results in higher mixing efficiency. It was found that using the melt pump leads to up to two times higher residence time and, consequently, higher level of material reinforcement as investigated by extensional rheology. Different melt pump adjustments, screw geometries, and screw speeds were tested and their effect on processing characteristics and material reinforcement was investigated. © 2009 Wiley Periodicals, Inc.

A drumbeat-pattern based error concealment method for music streaming applications (2002)

This paper presents a novel drumbeat-pattern based error concealment scheme, which detects the drumbeat-pattern of music signals on the encoder side and embeds the beat information as ancillary data in a preceding data unit in the compressed bitstream. The embedded beat information is then used to perform an error concealment task on the decoder side. The proposed method was implemented using an MPEG-4 AAC (Advanced Audio Coding) codec. Informal evaluations have shown that the proposed active error concealment method clearly improved the overall subjective sound quality in comparison with conventional methods if the packet losses include the drumbeats.
Synthesis of Cbz-Protected Ketomethylene Dipeptide lsosteres (2003)

Ketomethylene peptide isosteres have been the focus of a variety of synthetic studies because of their potential as therapeutic agents in the treatment of medical conditions mediated by proteases (1-3). The dipeptide core units 1 are chemically characterized by a 1,4-disposition of the carbonyl groups (ketone and carboxylate) and have an alkyl group at C-2 that is a chiral center. Protecting groups at amino nitrogen (typically carbamate such as Cbz or Boc) and the carboxyl group (typically ester) are usually present to make processing easier but must be readily and independently removable to permit extension in either the N-terminal or C-terminal directions (Fig. 1). Figure 1.
The propagation speed of a positive lightning return stroke (1987)

The first direct determination of the propagation speed of a lightning return stroke lowering positive charge to ground has been made. This stroke was the third of eight otherwise negative strokes in a triggered lightning flash initiated at the Kennedy Space Center, Florida. Two independent optical systems, one photographic and the other photoelectric, yielded common recordings for the third and fourth strokes; the respective two‐dimensional return stroke propagation speeds were 1.0 vs. 0.93 ×10 8 m/s for the positive (third) stroke and 1.0 vs. 1.0 ×10 8 m/s for the fourth stroke. Using fast electric‐field data, we estimated the positive stroke peak current to be 21 kA. Photoelectric data only yielded propagation speeds of 1.4, 1.6, 1.2, 1.3, 1.0 and 0.90 × 10 8 m/s for the first, second and fifth through eighth return strokes, respectively. All propagation speeds were evaluated over 850 m of channel near ground and have an error estimate of 10‐15%. For this positive stroke, we found a return stroke propagation speed typical of negative strokes. Whether positive return strokes, in general, travel at typical negative return stroke speeds must await future measurements.
Overtaking Safety Evaluation and Setting of Auxiliary Lane on Two-Lane Highway in China (2016)

Overtaking experiments on four two-lane highways were conducted. The data of overtaking conflict time (the time difference between the time of driving back to the original lane and the time of meeting with the first opposing vehicle) and experimental drivers’ risk feeling were observed. Membership was adopted to denote the experimental drivers’ risk feelings which also denote the severity of traffic conflict. Membership ranges from 0 to 1 and corresponding risk becomes higher; that is, traffic conflict becomes more serious. According to the observed relationship between overtaking conflict time, and drivers’ risk feeling membership, Cauchy distribution function was adopted as membership function. The thresholds of the severity of traffic conflict were determined through Delphi method. The relationship model among traffic volume, overtaking conflict time and design speed was established according to experimental data. Then the idea of setting auxiliary lane on two-lane highway in China was presented. And the traffic volume values that need setting auxiliary lane corresponding to different design speed and traffic conflict degree were given according to the established model. It is expected to improve the traffic safety level of two-lane highway in China through setting auxiliary lane.
