Blockade of Ca<sup>2+</sup>-Permeable AMPA/Kainate Channels Decreases Oxygen–Glucose Deprivation-Induced Zn<sup>2+</sup>Accumulation and Neuronal Loss in Hippocampal Pyramidal Neurons (2002)

Synaptic release of Zn2+ and its translocation into postsynaptic neurons probably contribute to neuronal injury after ischemia or epilepsy. Studies in cultured neurons have revealed that of the three major routes of divalent cation entry, NMDA channels, voltage-sensitive Ca2+ channels (VSCCs), and Ca2+-permeable AMPA/kainate (Ca-A/K) channels, Ca-A/K channels exhibit the highest permeability to exogenously applied Zn2+. However, routes through which synaptically released Zn2+ gains entry to postsynaptic neurons have not been characterized in vivo. To model ischemia-induced Zn2+ movement in a system approximating the in vivo situation, we subjected mouse hippocampal slice preparations to controlled periods of oxygen and glucose deprivation (OGD). Timm's staining revealed little reactive Zn2+ in CA1 and CA3 pyramidal neurons of slices exposed in the presence of O2 and glucose. However, 15 min of OGD resulted in marked labeling in both regions. Whereas strong Zn2+ labeling persisted if both the NMDA antagonist MK-801 and the VSCC blocker Gd3+ were present during OGD, the presence of either the Ca-A/K channel blocker 1-naphthyl acetyl spermine (NAS) or the extracellular Zn2+ chelator Ca2+ EDTA substantially decreased Zn2+ accumulation in pyramidal neurons of both subregions. In parallel experiments, slices were subjected to 5 min OGD exposures as described above, followed 4 hr later by staining with the cell-death marker propidium iodide. As in the Timm's staining experiments, substantial CA1 or CA3 pyramidal neuronal damage occurred despite the presence of MK-801 and Gd3+, whereas injury was decreased by NAS or by Ca2+ EDTA (in CA1).

A short review of recent advances in CO<sub>2</sub>hydrogenation to hydrocarbons over heterogeneous catalysts (2018)

CO<sub>2</sub> hydrogenation to hydrocarbons is a promising way of making waste to wealth and energy storage, which also solves the environmental and energy issues caused by CO<sub>2</sub> emissions. Much efforts and research are aimed at the conversion of CO<sub>2</sub> <i>via</i> hydrogenation to various value-added hydrocarbons, such as CH<sub>4</sub>, lower olefins, gasoline, or long-chain hydrocarbons catalyzed by different catalysts with various mechanisms. This review provides an overview of advances in CO<sub>2</sub> hydrogenation to hydrocarbons that have been achieved recently in terms of catalyst design, catalytic performance and reaction mechanism from both experiments and density functional theory calculations. In addition, the factors influencing the performance of catalysts and the first C-C coupling mechanism through different routes are also revealed. The fundamental factor for product selectivity is the surface H/C ratio adjusted by active metals, supports and promoters. Furthermore, the technical and application challenges of CO<sub>2</sub> conversion into useful fuels/chemicals are also summarized. To meet these challenges, future research directions are proposed in this review.

Evaporated CoPt alloy films with strong perpendicular magnetic anisotropy (1992)

CoPt alloy films with large perpendicular magnetic anisotropy, perpendicular coercivity, and saturated perpendicular remanence are reported. These films were fabricated by e-beam evaporation at substrate temperatures near 200 °C and above. Well-(111)-textured Pt underlayers are shown to dramatically increase the perpendicular magnetic anisotropy of CoPt alloy films. The large perpendicular magnetic anisotropy is shown to be strongly related to good CoPt(111) texture, and not to the ordered tetragonal Co50Pt50 phase.
The Process Simulation Using by Virtual Reality (2014)

Nowadays companies can solve production systems problems by variety of software solutions, but in practice it is known that it is often difficult to interpret these outputs, illustrate and to further integrate. One possibility is the use of augmented virtual reality for the planning of these systems. This article deals with the construction of the experimental sorting workplace as a model case of the production system. Weak points of solution are solved using augmented virtual reality, which helps to simulate the process in real time, in this case the virtual displayed product moving on belt conveyor before testing the real piece.
Predictive Comparisons of Procalcitonin (PCT) Level, Arterial Ketone Body Ratio (AKBR), APACHE III Score and Multiple Organ Dysfunction Score (MODS) in Systemic Inflammatory Response Syndrome (SIRS) (2004)

Procalcitonin (PCT) is a newly introduced marker of systemic inflammation and bacterial infection. A marked increase in circulating PCT level in critically ill patients has been related with the severity of illness and poor survival. The goal of this study was to compare the prognostic power of PCT and three other parameters, the arterial ketone body ratio (AKBR), the acute physiology, age, chronic health evaluation (APACHE) III score and the multiple organ dysfunction score (MODS), in the differentiation between survivors and nonsurvivors of systemic inflammatory response syndrome (SIRS). The study was performed in 95 patients over 16 years of age who met the criteria of SIRS. PCT and AKBR were assayed in arterial blood samples. The APACHE III score and MODS were recorded after the first 24 hours of surgical ICU (SICU) admission and then daily for two weeks or until either discharge or death. The patients were divided into two groups, survivors (n=71) and nonsurvivors (n=24), in accordance with the ICU outcome. They were also divided into three groups according to the trend of PCT level: declining, increasing or no change. Significant differences between survivors and nonsurvivors were found in APACHE III score and MODS throughout the study period, but in PCT value only up to the 7th day and in AKBR only up to the 3rd day. PCT values of the three groups were not significantly different on the first day between survivors and nonsurvivors. Receiver operating characteristic (ROC) curves for prediction of mortality by PCT, AKBR, APACHE III score and MODS were 0.690, 0.320, 0.915 and 0.913, respectively, on the admission day. In conclusion, PCT could have some use as a mortality predictor in SIRS patients but was less reliable than APACHE III score or MODS.
Pricing the constant elasticity of variance trinary option (2011)

The constant elasticity of variance(CEV) model can prevent the empirical bias exhibited by the Black-Scholes model such as the volatility smile.In this article,CEV model was used to describe the underlying asset price dynamics.The analytical pricing formula for the trinary option was derived in terms of complementary noncentral chi-square distribution function.A simply and efficient algorithm for computing this complementary distribution function was presented.Approximation to this complementary distribution function was provided to estimate accurately the result of the pricing formula derived above when the computation of the exact solution is problematic.This study will pave a new way to evaluate the class of the exotic option in the time dependent constant elasticity of variance.
A state-of-the-art review on magnetorheological elastomer devices (2014)

During the last few decades, magnetorheological (MR) elastomers have attracted a significant amount of attention for their enormous potential in engineering applications. Because they are a solid counterpart to MR fluids, MR elastomers exhibit a unique field-dependent material property when exposed to a magnetic field, and they overcome major issues faced in magnetorheological fluids, e.g. the deposition of iron particles, sealing problems and environmental contamination. Such advantages offer great potential for designing intelligent devices to be used in various engineering fields, especially in fields that involve vibration reduction and isolation. This paper presents a state of the art review on the recent progress of MR elastomer technology, with special emphasis on the research and development of MR elastomer devices and their applications. To keep the integrity of the knowledge, this review includes a brief introduction of MR elastomer materials and follows with a discussion of critical issues involved in designing magnetorheological elastomer devices, i.e. operation modes, coil placements and principle fundamentals. A comprehensive review has been presented on the research and development of MR elastomer devices, including vibration absorbers, vibration isolators, base isolators, sensing devices, and so on. A summary of the research on the modeling mechanical behavior for both the material and the devices is presented. Finally, the challenges and the potential facing magnetorheological elastomer technology are discussed, and suggestions have been made based on the authors' knowledge and experience.
[A simultaneous determination of rifampin and 25-deacetylrifampicin in cerebrospinal fluid and plasma of rabbit by liquid chromatography]. (1987)

A liquid chromatographic assay was modified for the simultaneous determination of rifampin (R) and its major metabolite, 25-desacetylrifampin (25-DR) in cerebrospinal fluid (CSF) and plasma in the rabbit. R, 25-DR and the internal standard, p-methylaminobenzoic acid (PMAB), were in an acidified sample at pH 4.2 containing 2% ascorbic acid as anti-oxidant and extracted into organic solvent (diethylether:dichloromethane, 3:2). The residue of the solvent extract was dissolved in 75μl methanol. The concentration was analysed by a liquid chromatograph consisting of a LDC pump using a reversed phase pre-column (30μm C8) linked to a radial pak column (10μm C8). The compounds were eluted with acetonitrile-l0 mmol/L phosphate buffer, KH2PO4, at pH 3.5 (40:60, vol:vol). The eluates are detected at 254 nm. The assay has been used to investigate the disposition of R and 25-DR in CSF and plasma of the rabbits.
GEODYN2: A Bottomhole Assembly/Geological Formation Dynamic Interaction Computer Program (1985)

ABSTRACT This paper describes the current development of a three-dimensional transient dynamic finite element computer program, GEODYN2, capable of simulating the behavior of a rotating bottom hole assembly (BHA) interacting with a non-uniform formation. The GEODYN2 Program facilitates a very detailed analysis/ simulation of the behavior of a BHA with a polycrystalline diamond compact (PDC) bit and various stabilizer designs. The basic drill string mechanics implemented within the program, the overall algorithm, and the more pertinent modeling features which permit this level of analysis are briefly outlined. The implementation of these features and how they allow calculation of the response behavior of a bottom hole assembly are demonstrated. Although the development and enhancement of modeling capabilities within GEODYN2 is ongoing, it is anticipated that the preliminary verification results thus far generated will further the understanding of the response behavior of BHAs.
A new antigen on the epithelial membrane: its immunoperoxidase localisation in normal and neoplastic tissue. (1979)

Using antisera raised against defatted human cream we have demonstrated a new antigen on the epithelial membrane. An indirect immunoperoxidase technique on routinely processed histological sections was used, and we describe results which show that this antigen has a widespread but highly selective distribution, being apparently localised to membranes that have a secretory function. The antigen is carried by a variety of adenocarcinomas, suggesting that its localisation may have a role in the diagnosis and differential diagnosis of malignant disease.

스폰서쉽은 많은 기업들에서 마케팅 믹스의 중요한 부분으로 여겨지고 있다. 2010년 글로벌 스포츠 스폰서쉽의 집계된 총 가치는 46억 달러를 뛰어넘었으며, 이번 년도에는 5%의 성장률을 기대하고 있다. 싱가폴에서는 2011년부터 2013년까지 집계된 스폰서쉽의 총 가치는 108억 달러의 2퍼센트인 3억 달러가 증가하였다. 이러한 이유들을 통해 몇 년동안 스폰서쉽은 큰 잠재력과 긍정적인 경향을 지니고 있음을 알 수 있다. 스포츠 스폰서쉽은 계속해서 활발히 발달되어 지고 있으며 이러한 영향은 지역과 전 세계적으로 큰 영향을 미치고 있다. 또한, 싱가포르 스포츠의 허브 역할로서의 시작과 2015년에 개최된 28회 동남아시아 경기 대회 등은 스폰서쉽의 효과 연구를 검증할 수 있는 기회로 다가왔다. 현재까지 성행하고 있는 스포츠 스폰서쉽의 상당한 자원들을 밝히기 위해서, 이 연구는 스폰서쉽에 참여하는 기업의 주가 측정을 통해 스포츠 스폰서쉽의 효과를 알아보는 데 목적이 있다. 이를 위해 2009년 1월부터 2015년 3월까지의 총 23개의 스폰서쉽 발표문들을 종합하여 분석하였다. 주가 거래 창에서 7일 동안 걸쳐 발견된 사소한 이 연구는 제안 할 수 있다. 스포츠 스폰서쉽은 스폰서들을 위한 긍정적인 주가 상승을 초래하지 않다는 점을 제안할 수도 있다. 이 결과는 투자자들과 시장은 스포츠 스폰서쉽의 발표문들을 호의적으로 보지 않았다. 따라서 이 연구 기간 동안에 공유되지 않은 가격 반응은 스포츠 스폰서쉽 발표를 가리켰다.
Processing conditions and mechanical properties of high-speed steel parts fabricated using direct selective laser sintering (2003)

This paper reports the results of an investigation into the selective laser sintering of a prealloyed high-speed steel powder. The structured development of processing conditions for single lines, single layers and multiple layers of material is reported, as are the flexural modulus and strength of the single- and multiple layer components. Infiltration with bronze was used to improve the mechanical properties of the components and it is concluded that selective laser sintering of high-speed steel allied to bronze infiltration can produce material with the mechanical properties to allow for use in load-bearing applications, but that further work is required to improve the density, mechanical properties and build rate if selective laser sintering is to develop as a general manufacturing process for hard metals.
SRAF generation based on SGM/CTM contour line (2021)

With the continuous improvement of chip integration level, resolution enhancement techniques (RET) has become one of the important technologies to promote the continued development of process nodes, such as source mask optimization (SMO), optical proximity correction (OPC) and sub-resolution assist feature (SRAF). Model-based SRAFs are generated by the guidance of the Continuous Transmission Mask (CTM) or SRAF Guidance Map (SGM). During operation, a threshold combined with the ridge is used to extract a suitable location for SRAFs. However, this generation method ignores many details, resulting in the need to constantly adjust SRAFs referring to the SGM/CTM in the subsequent optimization process, which will undoubtedly increase the simulation time. Therefore, we propose a contour line based SRAFs generation method. The extreme value region and the gradient of CTM/SGM will be displayed intuitively, so that more precise positions can be obtained at the initial SRAFs extraction. The SRAFs will be extracted from the extreme value region, and have a distribution similar to the final result. The gradient of the contour line can also be referenced in the following steps to guide the SRAF cleanup. During cleanup process, the SRAFs at high altitude region will have higher priorities to ensure the image quality of main patterns. Another advantage of this method is that when extracting rules from the model-based method, different SRAF priorities can be set according to the contour line and be used in the rules, so as to improve the accuracy of rule-based SRAFs.
Gangliosides in early interactions between vesicular stomatitis virus and CER cells. (1985)

In the present report an attempt was made to elucidate the role of gangliosides in early interactions between vesicular stomatitis virus (VSV) and CER cells. Research was carried out to test the ability of gangliosides from mammal brains and from CER cells to inhibit viral attachment to susceptible cells. The incubation of VSV in the presence of gangliosides decreased the subsequent infection of CER cells by the virus. When similar experiments were performed with gangliosides inserted in liposomes the inhibition of infection was enhanced. Since carbohydrate moieties could participate to rhabdovirus binding as a part of a glycolipid receptor, CER cells were subjected to the action of glycosidases and these produced a fall in the viral attachment. Deglycosilated CER cells reacquired their susceptibility to virus infection after coating with gangliosides immediately after enzyme treatment. Results obtained show the participation of gangliosides in the receptorial structure for vesiculovirus of susceptible CER cells.
Effects of nucleoside transport inhibitors on the salvage and toxicity of adenosine and deoxyadenosine in L1210 and P388 mouse leukemia cells. (1985)

Incubation of deoxycoformycin-treated L1210 leukemia cells with dipyridamole or nitrobenzylthioinosine, inhibitors of nucleoside transport, enhanced the long-term incorporation of 2'-deoxyadenosine and adenosine into the nucleotide pool and the toxicity of 2'-deoxyadenosine for the cells. In contrast, 2'-deoxyadenosine uptake in deoxycoformycin-treated P388 leukemia cells, which was about 10 times greater than that in L1210 cells, was inhibited by dipyridamole and nitrobenzylthioinosine, and 2'-deoxyadenosine toxicity was not significantly affected by the transport inhibitors. P388 cells also were about 6 times more resistant to 2'-deoxyadenosine than were L1210 cells, in spite of the greater uptake of the nucleoside. We found that purine nucleoside transport in L1210 and P388 cells exhibited similar kinetic properties and sensitivity to dipyridamole and nitrobenzylthioinosine (both influx and efflux) and that the stimulation of 2'-deoxyadenosine uptake by the inhibitors in L1210 cells is not mediated at the level of its transport into the cells but rather reflects an enhanced intracellular net accumulation of deoxyadenosine nucleotides.
STL-less based CAD/CAM Approach for Laser Scanning in Micro Stereo Lithography (2014)

Micro Stereo Lithography (MSL) is an additive rapid prototyping process for fabrication of three dimensional micro parts that requires slicing of 3D model into layers and generation of laser tool path for each of the layer. To generate laser scan path, existing general purpose CAD/CAM software is being used in microstereolithography (MSL) set up built in house to fabricate micro parts. CAD/CAM software are used as aids for generating NC tool path for machining in metal working industries. Rapid Prototyping require specialized CAD/CAM packages to generate laser tool path for macro sized components. Most of the existing rapid prototyping softwares utilize STL format files for slicing and generation of tool path. This paper describes about adapting the standard CAD/CAM package and utilizing its features for generating laser tool path for manufacture of 3D miniature parts using MSL. This approach has reduced the overall time required for product development.
Overview of image-based 3D vision systems for agricultural applications (2017)

Various agricultural robots exist which are intended to help farmers to make decisions. Vision systems are an integral and essential part of these agricultural robots to perceive and evaluate the work space, inspect crops and detect objects. The use of 3D vision systems can provide a 3D reconstructed model which will supply detailed information including depth estimation about a crop or an object or environmental structures. However, these vision systems have some drawbacks which are limiting their use in an agricultural area. The limiting factors are dealing with lighting conditions, navigating unstructured environment, harvesting speed, occlusion and overlapping of fruits, accuracy of the system etc. This paper investigates the limitations and challenges of the state-of-the-art of 3D image reconstruction techniques in agricultural applications. Active and passive approaches have been reviewed. Factors to be considered while designing the vision system have been identified.
Fructooligosaccharides: a review. (1988)

Fructooligosaccharides are naturally occurring compounds that have been reported in a variety of plants. Neosugar is a fructooligosaccharide mixture of 1F-(1-beta-fructofuranosyl)-sucrose polymers which is produced on a commercial scale from sucrose using a fungal fructosyltransferase. The resulting product is 0.4 to 0.6 times as sweet as sugar and is resistant to digestion by mammalian alpha-amylase, sucrase and maltase. Although Neosugar is non-digestible in humans, it is selectively utilized by bifidobacteria. Neosugar has been examined extensively in human and animal studies which indicate a lack of toxicity, carcinogenicity and genotoxic effects. Neosugar is used as a feed additive for poultry and swine in Japan and has been approved in foods as a raw material. Additional studies in progress in the US suggest that it could provide an economic alternative as an additive to poultry and swine feed.
Experimental Oral Infection of Specific Pathogen‐free Laying Hens and Cocks with <i>Salmonella enteritidis</i> Strains (1995)

A total of 105 specific pathogen-free (SPF) laying hens and eight cocks were orally infected with strains of Salmonella enteritidis. The organs of these animals were examined bacteriologically for up to 6 weeks post infectionem (p.i.). One-half of the eggs laid on a single day were examined 1 day after laying, and the other half 28 days after laying. The siderophore, ferrioxamine E, was added to the pre-enrichment medium. A high correlation was found to exist between colonization of the caecum by salmonellas and the level of contamination of the egg shell. No correlation was found between the contamination of the egg shell and that of the egg content. The strains used for infection were not recovered from any yolk out of a total of 938 eggs. S. enteritidis was isolated from the albumen in four cases (0.4%). Storage of the eggs for 28 days after laying resulted in a decrease in the frequency of salmonella detection on the egg shell and in the egg content. The strains used for infection could be isolated from various sections of the sexual organs for up to 2 weeks p.i. S. enteritidis was most frequently found in the ovary and rarely in the oviduct, but never in the pre-ovulatory mature follicles. In the groups that included salmonella-infected cocks, the salmonella detection frequency did not increase either for the egg content or for the organs of the laying hens. It seems that primary vertical transmission of salmonellas occurs, in rare cases, as a result of an infection of the albumen but not of the yolk.
