An Integrated Inspection Method based on Machine Vision for Solder Paste Depositing (2007)

The solder paste depositing inspection is very important in the process of surface mounting for print circuit board (PCB). An integrated inspection approach based on the machine vision was presented in the study. The method developed in this paper can identify the major defects of the solder paste depositing, such as displacement, deficiency, excess, bridge and overflow. Firstly, position compensation is applied to improve the inspection accuracy. Secondly, an image enhancement algorithm based on the texture is developed, which can enlarge the differences of the grayscale values between the PCB images and the solder paste images. Thirdly, the images of the printed PCB are analyzed by using the particle analysis method and the two-dimensional (2D) inspection results are obtained. A pseudo three-dimensional (3D) inspection approach is further proposed to identify the defects in the 3D state. Finally, experiment results are presented, which illustrate the validity of the approach.
Analysis of the Legionella longbeachae Genome and Transcriptome Uncovers Unique Strategies to Cause Legionnaires' Disease (2010)

Legionella pneumophila and L. longbeachae are two species of a large genus of bacteria that are ubiquitous in nature. L. pneumophila is mainly found in natural and artificial water circuits while L. longbeachae is mainly present in soil. Under the appropriate conditions both species are human pathogens, capable of causing a severe form of pneumonia termed Legionnaires' disease. Here we report the sequencing and analysis of four L. longbeachae genomes, one complete genome sequence of L. longbeachae strain NSW150 serogroup (Sg) 1, and three draft genome sequences another belonging to Sg1 and two to Sg2. The genome organization and gene content of the four L. longbeachae genomes are highly conserved, indicating strong pressure for niche adaptation. Analysis and comparison of L. longbeachae strain NSW150 with L. pneumophila revealed common but also unexpected features specific to this pathogen. The interaction with host cells shows distinct features from L. pneumophila, as L. longbeachae possesses a unique repertoire of putative Dot/Icm type IV secretion system substrates, eukaryotic-like and eukaryotic domain proteins, and encodes additional secretion systems. However, analysis of the ability of a dotA mutant of L. longbeachae NSW150 to replicate in the Acanthamoeba castellanii and in a mouse lung infection model showed that the Dot/Icm type IV secretion system is also essential for the virulence of L. longbeachae. In contrast to L. pneumophila, L. longbeachae does not encode flagella, thereby providing a possible explanation for differences in mouse susceptibility to infection between the two pathogens. Furthermore, transcriptome analysis revealed that L. longbeachae has a less pronounced biphasic life cycle as compared to L. pneumophila, and genome analysis and electron microscopy suggested that L. longbeachae is encapsulated. These species-specific differences may account for the different environmental niches and disease epidemiology of these two Legionella species.
Genomic Encyclopedia of Bacteria and Archaea: Sequencing a Myriad of Type Strains (2014)

Microbes hold the key to life. They hold the secrets to our past (as the descendants of the earliest forms of life) and the prospects for our future (as we mine their genes for solutions to some of the planet's most pressing problems, from global warming to antibiotic resistance). However, the piecemeal approach that has defined efforts to study microbial genetic diversity for over 20 years and in over 30,000 genome projects risks squandering that promise. These efforts have covered less than 20% of the diversity of the cultured archaeal and bacterial species, which represent just 15% of the overall known prokaryotic diversity. Here we call for the funding of a systematic effort to produce a comprehensive genomic catalog of all cultured Bacteria and Archaea by sequencing, where available, the type strain of each species with a validly published name (currently∼11,000). This effort will provide an unprecedented level of coverage of our planet's genetic diversity, allow for the large-scale discovery of novel genes and functions, and lead to an improved understanding of microbial evolution and function in the environment.
Gemcitabine Plus Docetaxel Versus Docetaxel in Patients With Predominantly Human Epidermal Growth Factor Receptor 2–Negative Locally Advanced or Metastatic Breast Cancer: A Randomized, Phase III Study by the Danish Breast Cancer Cooperative Group (2011)

GD compared with docetaxel demonstrated increased TTP in metastatic breast cancer. However, RR and OS were similar. Thus, the addition of gemcitabine failed to demonstrate any clinically meaningful benefit when combined with docetaxel.
Spatial and temporal variation of MOPITT CO in Africa and South America: A comparison with SHADOZ ozone and MODIS aerosol (2004)

Carbon monoxide (CO) measurements from the Measurements of Pollution in the Troposphere (MOPITT) experiment are used to explore the correlation between biomass burning and ozone profiles at six tropical stations namely Reunion, Irene, Natal, Ascension, San Cristobal, and Paramaribo. Distinct seasonal patterns of CO at each station indicate the strong influence of African and South American biomass burning. All stations show enhanced CO columns during September–November (SON) corresponding to austral burning. Furthermore, the effects of Sahelian burning can be seen at Natal and Ascension. Similarly, the signature of northern Amazonian fires can be observed at San Cristobal. The CO variations are generally similar to the variations of aerosol optical depth (AOD) retrieved contemporaneously from Moderate Resolution Imaging Spectroradiometer (MODIS) at most stations, with notable differences at Irene, San Cristobal, and Paramaribo. Tropospheric ozone from Southern Hemisphere Additional Ozonesonde (SHADOZ) ozonesonde measurements at all stations show elevated levels, corresponding to the CO enhancements in SON months. However, there are several instances of ozone enhancements unaccompanied by any CO increase. This might indicate that sources other than biomass burning such as stratospheric tropospheric exchange (STE) or lightning related NO x may be operative. At San Cristobal, strong CO enhancements during March–April are not accompanied by any significant change in ozone.
Humoral and cellular immune responses up to 7·5 years after administration of streptokinase for acute myocardial infarction (1999)

There is as yet no evidence of a time limit beyond which administration of streptokinase on a second occasion can be regarded as safe and likely to be effective. Measurement of neutralizing anti-streptokinase or total anti-streptokinase IgG titre appear to provide equivalent information regarding the antibody status of a population. Further studies are required regarding the apparent lack of peripheral blood mononuclear cells responsiveness in patients previously exposed to streptokinase.
Application of cis-2-amino-3,3-dimethyl-1-indanol as an efficient chiral auxiliary to the asymmetric Ireland-Claisen rearrangement. Improvement of the diastereoselectivity by combinational use of chlorodimethylsilane as a silylating agent (2000)

The asymmetric Ireland-Claisen rearrangement of allyl carboxylates having a chiral substituent at the alpha-position of the carboxylate part gave the desired products with excellent diastereoselectivity, when an oxazolidinone, which was prepared from a non-natural chiral auxiliary, (1R,2S)-cis-2-amino-3,3-dimethyl-l-indanol, was used as the chiral substituent. Furthermore, the diastereoselectivity was improved by using chlorodimethylsilane as a silylating agent of the intermediary enolates.
A Milstar low profile antenna (2003)

A low profile antenna/pedestal system for the Milstar program was developed at Raytheon under an Air Force contract. The system was designed to have minimum intrusion inside the aircraft and no protrusion outside the aircraft so that the radome is flush to the fuselage. The main drivers of this antenna design include low cost, minimum height, and high efficiencies for both K-band (20.2-21.2 GHz) and Q-band (43.5-45.5 GHz).

Progress on the Critical Parameters for Lithium–Sulfur Batteries to be Practically Viable (2018)

Abstract Lithium–sulfur batteries have great potential to satisfy the increasing demand of energy storage systems for portable devices, electric vehicles, and grid storage because of their extremely high specific capacity, cost‐effectiveness, and environmental friendliness. In spite of all these merits, the practical utilization of lithium–sulfur batteries is impeded by commonly known challenges, such as low sulfur utilization (<80%), short life (<200 cycles), fast capacity fade, and severe self‐discharge effect, which mainly result from the i) low conductivity of the active material, ii) serious polysulfide shuttling, iii) large volume changes, and iv) lithium–metal anode contamination/corrosion. Numerous approaches are reported to effectively mitigate these issues. Indeed, such approaches have shown enhanced lithium–sulfur battery performances. However, many reports overlook the critical parameters, including sulfur loading (<13 mg cm −2 ), sulfur content (<70 wt%), and electrolyte/sulfur ratio (>11 µL mg −1 ), that significantly affect the analyzed electrochemical characteristics, energy density, and practicality of lithium–sulfur batteries. This review highlights the trends and progress in making cells fulfilling these fabrication parameters and discuss the challenges of the amount of sulfur and electrolyte in fabricating cells with practically necessary parameters and with high electrochemical utilization and efficiency.
Electromechanical capacitor for energy transfer (1983)

Inductive energy transfer between two magnets can be achieved with almost 100% efficiency with a transfer capacitor. However, the bulk and cost will be high, and reliability low if conventional capacitors are used. A homopolar machine, used as a capacitor, will be compact and economical. A homopolar machine was designed with counter-rotating copper disks completely immersed in a liquid metal (NaK-78) to work as a pulse capacitor. Absence of solid-brush collectors minimized wear and frictional losses. Wetting of the copper disks throughout the periphery by the liquid metal minimized the resistive losses at the collector interface. A liquid-metal collector would, however, introduce hydrodynamic and magnetohydrodynamic losses. The selected liquid metal, e.g., NaK-78 will produce the lowest of such losses among the available liquid metals. An electromechanical capacitor of this design was tested at various dc magnetic fields. Its measured capacitance was about 100 farads at a dc magnetic field of 1.15 tesla.
Dispersion in the Nonlinear Susceptibility of GaP near the Reststrahl Band (1968)

This paper describes a continuation of earlier work, in which we reported measurements of the intensities of mixed frequencies from a 6328 \AA{} beam and various infrared frequencies near the lattice reststrahl resonance, and in which we gave a theory for the dispersion of the nonlinear susceptibility which governs the mixing process near the reststrahl resonance. With more infrared frequencies, with data on the anti-Stokes side as well as on the Stokes side, and with improved techniques, we can now give a more meaningful comparison with theory. These new data provide additional confirmation of the theory for the dispersion of the nonlinear susceptibility. We also describe the apparatus more fully, and we demonstrate some incidental features of the mixing.
Selective expansion of T cells expressing T-cell receptor variable regions Vβ2 and Vβ8 in Kawasaki disease (1992)

Kawasaki disease (KD) is an acute vasculitis complicated by the development of coronary artery abnormalities. The etiology of KD is unknown. Based on the observation that KD is associated with marked activation of T cells and monocyte/macrophages, we hypothesized that KD may be caused by a superantigen [e.g., a bacterial toxin that stimulates T cells expressing particular T-cell receptor .3 chain variable (V,B) gene segments]. Peripheral blood T cells from patients in the acute and convalescent phases of KD and from various control groups were analyzed for T-cell receptor V,B gene expression by using a quantitative PCR technique and cytofluorographic analysis with available anti-V,B monoclonal antibodies. Patients with acute KD demonstrated significantly elevated levels of circulating V,B2+ and V,B8.1+ T cells compared to the other control groups. None of the other 20 VJ3 populations analyzed by quantitative PCR were found to be significantly elevated. Using flow cytometry, we confirmed a significant elevation of T cells reactive with anti-Vj,8.1 and the lack of change in several other V,B subsets-i.e. V,B5.1, -5.2, -6.7, and -12. During the convalescence phase of KD, there was a reduction in the abnormal levels of V,B2+ and V,B8.1+ T cells. These observations suggest that KD may be caused by a superantigen and may provide insight into the nature of the
Improved excitation techniques for atmospheric pressure CO <sub>2</sub> lasers (1971)

A simple and rugged electrode structure is described for the production of uniform pulse-excited discharges throughout large volumes at atmospheric pressure. Output energy densities of 18 mJ/cm3 have been achieved in a multimode CO2 laser. The performance is compared with that of a novel mesh-cathode electrode system.
On the complexity of cooperative peer-to-peer repair for wireless broadcasting (2006)

The well-known NAK implosion problem for wireless broadcast can be addressed by leveraging cooperative peer-to-peer connectivity to repair corrupted data. This paper studies the cooperative peer-to-peer repair (CPR) framework for multimedia broadcast. We show that CPR can be formulated as an optimization problem that minimizes the number of iterations it takes to wirelessly disseminate a desired message from peers with the content to peers without it. Complicating the problem are transmission conflicts, where pre-specified sets of links cannot simultaneously transmit due to interference. In this paper, we formalize the CPR minimum delay problem and prove that it is NP-hard

Social Work Education in China: A Brief History and Contemporary Developments (2011)

Social work and social work education have gone through a rough and bumpy road after it was first introduced into China in the early twentieth century. This paper reviews the four phases of historical development of social work education in China, and its rapid development in the recent ten years. The author introduces Chinese government’s policies and strategies to expand social work services and social work education in recent years, and .also argues that social work education in China is still in a weak position and there are a number of potential problems and challenges standing in the way, but professional training and education are likely to be consolidated, increased, and improved.
Alkali-promoted gas adsorption and surface reactions on metals (1984)

Alkali metals adsorbed on transition metal surfaces do not only change the electronic properties of these metals but alter also their chemical reactivity. This effect is well known in heterogeneous catalysis as the promotion of metallic catalysts by alkali additives. The more fundamental physics of this effect is being studied by applying surface spectroscopies to coadsorbed layers of alkali and gas molecules (e.g., O2, N2, CO, NO) on well defined transition metal surfaces. These studies show that the adsorbed alkali causes the transfer of additional electronic charge into certain molecular orbitals of the adsorbed molecules. This electron transfer may weaken or strengthen the metal–adsorbate or intramolecular bonds. In some cases the dissociation of the adsorbed molecule occurs. Heterogeneous surface reactions on these alkali promoted samples show significant changes in both the surface composition of the catalyst and the gaseous product spectrum. Examples for this effect are given in connection with a study of CO hydrogenation on K-promoted Fe foils.
Observations Through a Transparent Oil Pan During Cold-Start, Short-Trip Service (1991)

<div class="htmlview paragraph">Cold-start, short-trip driving causes the accumulation of fuel, water, and other contaminants in oil. In this type of service the engine oil degrades at a rapid rate. To gain a better understanding of the degradation, the oil under these conditions was observed and photographed through a transparent oil pan. In addition the oil was analyzed to provide a quantitative measure of the degradation. Oil analysis results confirmed what was observed visually; once oil became warmer, sludge and contaminants were removed, and many of the oil's properties (acid number, pentane insolubles, water in oil, etc.) improved.</div>
A fusion-based video quality assessment (fvqa) index (2014)

In this work, we study the visual quality of streaming video and propose a fusion-based video quality assessment (FVQA) index to predict its quality. In the first step, video sequences are grouped according to their content complexity to reduce content diversity within each group. Then, at the second step, several existing video quality assessment methods are fused to provide the final video quality score, where fusion coefficients are learned from training video samples in the same group. We demonstrate the superior performance of FVQA as compared with other video quality assessment methods using the MCL-V video quality database.
