The triglyceride composition, structure, and presence of estolides in the oils of<i>Lesquerella</i> and related species (1995)

Members of the genus Lesquerella , native to North America, have oils containing large amounts of hydroxy fatty acids and are under investigation as potential new crops. The triglyceride structure of oils from twenty‐five Lesquerella species in the seed collection at our research center has been examined after being hydrolysis‐catalyzed by reverse micellar‐encapsulated lipase and alcoholysis‐catalyzed by immobilized lipase. These reactions, when coupled with supercritical‐fluid chromatographic analysis, provide a powerful, labor‐saving method for oil triglyceride analysis. A comprehensive analysis of overall fatty acid composition of these oils has been conducted as well. Lesquerella oils (along with oils from two other Brassicaceae: Physaria floribunda and Heliophilia amplexicaulis ) have been grouped into five categories: densipolic acid‐rich (Class I); auricolic acid‐rich (Class II); lesquerolic acid‐rich (Class III); an oil containing a mixture of hydroxy acids (Class IV); and lesquerolic and erucic acid‐rich (Class V). The majority of Class I and II triglycerides contain one or two monoestolides at the 1‐ and 3‐glycerol positions and a C 18 polyunsaturated acyl group at the 2‐position. Most Class III and IV oil triglycerides contain one or two hydroxy acids at the 1‐ and 3‐positions and C 18 unsaturated acid at the 2‐position. A few of the Class III oils have trace amounts of estolides. The Class V oil triglycerides are mostly pentaacyl triglycerides and contain monestolide and small amounts of diestolide. Our triglyceride structure assignments were supported by 1 H nuclear magnetic resonance data and mass balances.
The Specific Identification of Fæcal Pellets (1931)

In fine muds such as those covering most of the bottom in the deeper parts of the Clyde Sea Area the formation of fæcal pellets is a factor of great biological importance. In these muds up to 40 per cent of the fine material is often consolidated into fæcal masses, and in extreme cases even the whole of the mud may be in the form of pellets. The significance of this process is clear. In the first place, the effective particle size of a large proportion of the mud is very greatly increased, and this in turn affects such characters as the porosity of the bottom, and the liability of the material to be transported by currents. In the second place, among selective feeders such as Syndosmya alba , which feed on the mud, there is an economy of labour, in that food which has once passed through the gut is set aside in a form in which it will be refused if again taken in by the siphons. This latter process can readily be seen in the example cited whose rejecta on examination prove to be almost entirely composed of pellets of its own and other species.
The Effect of Intravenous Infusion of L-Arginine, Glycine and D-Lysine on Urinary Calcium Excretion in the Rat. (1995)

Standard renal clearance techniques were used to compare the effects of intravenous infusions of L-arginine, D-lysine and glycine on urinary calcium excretion in the rat. A significant calciuric response was evident following the infusion of all three amino acids in all the animals. The maximal effect was evident in rats receiving L-arginine. The mechanism for the increased urinary calcium excretion in rats infused with L-arginine and D-lysine appeared more due to a decreased fractional reabsorption of this cation as no significant changes in the glomerular filtration rate (GFR) were evident in these two groups. The calciuria in rats receiving glycine appears due to increased filtered load secondary to the increased GFR, suggesting that the mechanism for calciuria evident following protein ingestion or amino acid infusion may vary and may be dependent upon the amino acid ingested or infused.
An Edge Extraction Method Using K-means Clustering In Image (2014)

본 논문에서는 복잡한 영상에서의 윤곽선 검출을 기존의 방법보다 더 명확하고 효율적으로 나타내기 위해서 K-means 군집화를 이용하였다. 제안하는 방법에는 세 가지 단계를 거친다. 첫 번째는 명암분포를 균일하게 하기 위하여 히스토그램 평활화를 사용한다. 두 번째는 거리에 기반을 둔 클러스터링 기법으로 기준점에서 가까운 곳의 데이터들을 하나의 군집으로 묶는 K-means 군집화를 사용하고 마지막으로 에지검출의 가장 대표적인 1차 미분 연산자인 소벨 마스크를 사용하여 윤곽선을 검출한다. 따라서 기존에 있던 윤곽선 검출보다 더 나은 결과로 명확하게 윤곽선을 검출 할 수 있음을 보인다. A method for edge detection using K-means clustering is proposed in this paper. The method is performed through there steps. Histogram equalizing is applied to the image for the uniformed intensity distribution. Pixels are clustered by K-means clustering technique. Then Sobel mask is applied to detect edges. Experiments showed that this method detected edges better than conventional method.

PUBLIC OPINION REGARDING PHOTO RADAR (1989)

Photo radar is an automated speed surveillance system that photographs the vehicle, driver, and license plate number of speeders so that citations can be sent by mail. A telephone survey was conducted among residents of two communities (Paradise Valley, Arizona and Pasadena, California) where photo radar is currently being used in the United States; residents of nearby communities were also surveyed. Considerable awareness that photo radar was being used was found, especially in Paradise Valley where 72% mentioned it spontaneously. In all areas combined, 58% either approved or strongly approved its use; residents of Paradise Valley and Pasadena were more likely to approve than residents of nearby communities. Two-thirds of those who approved of photo radar thought its use should be increased. Almost half of the respondents who knew about photo radar being used said it had made them drive slower.
Sla2p Is Associated with the Yeast Cortical Actin Cytoskeleton via Redundant Localization Signals (1999)

Sla2p, also known as End4p and Mop2p, is the founding member of a widely conserved family of actin-binding proteins, a distinguishing feature of which is a C-terminal region homologous to the C terminus of talin. These proteins may function in actin cytoskeleton-mediated plasma membrane remodeling. A human homologue of Sla2p binds to huntingtin, the protein whose mutation results in Huntington's disease. Here we establish by immunolocalization that Sla2p is a component of the yeast cortical actin cytoskeleton. Deletion analysis showed that Sla2p contains two separable regions, which can mediate association with the cortical actin cytoskeleton, and which can provide Sla2p function. One localization signal is actin based, whereas the other signal is independent of filamentous actin. Biochemical analysis showed that Sla2p exists as a dimer in vivo. Two-hybrid analysis revealed two intramolecular interactions mediated by coiled-coil domains. One of these interactions appears to underlie dimer formation. The other appears to contribute to the regulation of Sla2p distribution between the cytoplasm and plasma membrane. The data presented are used to develop a model for Sla2p regulation and interactions.

A comprehensive experimental investigation of tubular entry flow of viscoelastic fluids. Part II. The velocity field in stable flow (1978)

Abstract Center‐line velocities and developing velocity profiles are presented for viscoelastic fluids flowing in a 2:1 and 4:1 abrupt entry contraction. Two flow regimes are clearly identified: a vortex growth regime and a divergent flow regime. Dramatic differences in the velocity field are observed and discussed for the two flow regimes. A kinematic model based on the velocity field data is proposed for vortex growth flow.
Molecular and functional regulation of two NO<sub>3</sub><sup>–</sup> uptake systems by N‐ and C‐status of <i>Arabidopsis</i> plants (1999)

Root NO3- uptake and expression of two root NO3- transporter genes (Nrt2;1 and Nrt1) were investigated in response to changes in the N- or C-status of hydroponically grown Arabidopsis thaliana plants. Expression of Nrt2;1 is up-regulated by NO3 - starvation in wild-type plants and by N-limitation in a nitrate reductase (NR) deficient mutant transferred to NO3- as sole N source. These observations show that expression of Nrt2;1 is under feedback repression by N-metabolites resulting from NO3- reduction. Expression of Nrt1 is not subject to such a repression. However, Nrt1 is over-expressed in the NR mutant even under N-sufficient conditions (growth on NH4NO3 medium), suggesting that expression of this gene is affected by the presence of active NR, but not by N-status of the plant. Root 15NO3- influx is markedly increased in the NR mutant as compared to the wild-type. Nevertheless, both genotypes have similar net 15NO3- uptake rates due to a much larger 14NO3- efflux in the mutant than in the wild-type. Expressions of Nrt2;1 and Nrt1 are diurnally regulated in photosynthetically active A. thaliana plants. Both increase during the light period and decrease in the first hours of the dark period. Sucrose supply prevents the inhibition of Nrt2;1 and Nrt1 expressions in the dark. In all conditions investigated, Nrt2;1 expression is strongly correlated with root 15NO3- influx at 0.2 mM external concentration. In contrast, changes in the Nrt1 mRNA level are not always associated with similar changes in the activities of high- or low-affinity NO3- transport systems.
Physical Activity Recognition Using a Single Tri-Axis Accelerometer (2009)

Ver the past two decades, a striking increase in the number of people with the metabolic syndrome worldwide has taken place. This increase is associated with the global epidemic of obesity and diabetes. With the elevated risk not only of diabetes but also of cardiovascular disease from the metabolic syndrome, there is urgent need for strategies to prevent the emerging global epidemic [1,2]. Although the metabolic syndrome appears to be more common in people who are genetically susceptible, acquired underlying risk factors-being overweight or obese, physical inactivity, and an atherogenic diet-commonly elicit clinical manifestations [3].
A low voltage, high-speed alterable N-channel nonvolatile memory (1978)

The structure and principle of a new nonvolatile charge storage device are described. The Floating Si-gate Channel Corner Avalanche Transition (FCAT) memory device is an n-channel MOS transistor with a floating gate. The p <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">+</sup> regions are placed outside the channel area by aligning them with the floating gate and are adjacent to the diffused n <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">+</sup> source and/or drain regions. This device can operate write/erase modes under low voltage (12 V) and high speed (< 1 ms) conditions using only a pair of positive pulses. This is achieved with a novel avalanche transition at the channel corner through a relatively thin oxide under the open drain condition.
Establishment of Human Neural Progenitor Cells from Human Induced Pluripotent Stem Cells with Diverse Tissue Origins (2016)

Human neural progenitor cells (hNPCs) have previously been generated from limited numbers of human induced pluripotent stem cell (hiPSC) clones. Here, 21 hiPSC clones derived from human dermal fibroblasts, cord blood cells, and peripheral blood mononuclear cells were differentiated using two neural induction methods, an embryoid body (EB) formation-based method and an EB formation method using dual SMAD inhibitors (dSMADi). Our results showed that expandable hNPCs could be generated from hiPSC clones with diverse somatic tissue origins. The established hNPCs exhibited a mid/hindbrain-type neural identity and uniform expression of neural progenitor genes.
USERS PREFERENCE-BASED COLOR TRANSFORMATION USING INTERACTIVE GENETIC ALGORITHM (2010)

In this paper, we propose a new color transform method in the image based on the users preferences. To obtain general preferences for color, we first divided the images into two categories as favourable and unfavourable groups based on the users evaluation. From the categorized groups of images, we compute color histograms to construct general templates for 8 primary colors. To reflect the users own preference in the color perception, we adopted an interactive genetic algorithm. In the interactive genetic algorithm, each individual consists of three chromosomes for H, S, and V and the fitness value is computed from the users input, which is then used as criteria to iterate Genetic Algorithm for learning the users preference. Finally, a personalized individual is generated. By transforming the colors in the image with the personalized individual, a re-colorred image is generated according to the user own preference. Survey results show that re-colorred images from our proposed personalized color templates are more satisfying than the original images.
Translational Control of Protein Kinase Cη by Two Upstream Open Reading Frames (2009)

Protein kinase C (PKC) represents a family of serine/threonine kinases that play a central role in the regulation of cell growth, differentiation, and transformation. Posttranslational control of the PKC isoforms and their activation have been extensively studied; however, not much is known about their translational regulation. Here we report that the expression of one of the PKC isoforms, PKCeta, is regulated at the translational level both under normal growth conditions and during stress imposed by amino acid starvation, the latter causing a marked increase in its protein levels. The 5' untranslated region (5' UTR) of PKCeta is unusually long and GC rich, characteristic of many oncogenes and growth regulatory genes. We have identified two conserved upstream open reading frames (uORFs) in its 5' UTR and show their effect in suppressing the expression of PKCeta in MCF-7 growing cells. While the two uORFs function as repressive elements that maintain low basal levels of PKCeta in growing cells, they are required for its enhanced expression upon amino acid starvation. We show that the translational regulation during stress involves leaky scanning and is dependent on eIF-2alpha phosphorylation by GCN2. Our work further suggests that translational regulation could provide an additional level for controlling the expression of PKC family members, being more common than currently recognized.
Robot arm geometric link parameter estimation (1983)

A general method for estimating serial link manipulator geometric parameter errors is proposed in this paper. The positioning accuracy of the end-effector may be increased significantly by updating the nominal link parameters in the control software to represent the physical system more accurately. The proposed method is applicable for serial link manipulators with any combination of revolute or prismatic joints, and is not limited to a specific measurement technique.
A Real Time Radioactive Marker Technique For Measuring Valve Train Wear (1987)

<div class="htmlview paragraph">Valve train (VT) wear protection has become an increasingly important passenger car engine oil (PCEO) performance feature. Directionally higher levels of valve train wear have been noted with the development and continuous influx of fast-bum (combustion-efficient) engines into the U.S. automotive market in recent years (1979–present). Field testing has been a primary measure of severe engine VT wear performance. This type of testing has become increasingly more expensive, and time consuming, however. There was a need for a short-time, more cost-effective tool to help carry out our experimental work.</div> <div class="htmlview paragraph">A real-time Radioactive Marker Technique for measuring VT wear was developed to satisfy this need and to improve our flexibility in optimizing oil chemistry to meet engine VT wear requirements. This real-time technique involves surface layer activation (SLA) of one cam lobe in the engine's valve train with subsequent monitoring of the radioactive surface as wear occurs. The radioactive camshaft is placed in the engine and a motored wear test begun. A detector collects and monitors the emitted radiation as the engine is running. Radiation decreases as wear occurs and this relationship is used to follow the dynamic wear process. This technique allows one to monitor VT wear dynamically, as it occurs in a running engine, without taking the engine apart to physically measure the wear. However, most of today's quality PCEO's do not produce much VT wear over the relatively short (16 hrs) test period and an oil aging chemical, a hydroperoxide, was introduced into the wear test regime to relate better to longer term field service. Under the improved test regime, the oil and engine are first conditioned overnight to expose the engine's valve train to the oil's anti-wear technology, and then the oil-aging chemical is added, at a fixed rate once per hour, while the engine is motored and the wear process continues. The test is continued until a significant (≥1<i>μ</i>/hr) increase in wear rate occurs. The difference in time between the point of significant wear rate increase and the point of initial hydroperoxide addition is designated “The Time to Accelerated Wear”. The larger this number, the better the anti-wear capability of the oil being tested. Data from this Radioactive Marker Engine Test with oil aging suggests a correlation with VT wear observed after long term (50K miles, 8 months) field testing.</div>

Aquaporin 4 blockade improves survival of murine heart allografts subjected to prolonged cold ischemia (2017)

Prolonged cold ischemia storage (CIS) is a leading risk factor for poor transplant outcome. Existing strategies strive to minimize ischemia-reperfusion injury in transplanted organs, yet there is a need for novel approaches to improve outcomes of marginal allografts and expand the pool of donor organs suitable for transplantation. Aquaporins (AQPs) are a family of water channels that facilitate homeostasis, tissue injury, and inflammation. We tested whether inhibition of AQP4 improves the survival of fully MHC-mismatched murine cardiac allografts subjected to 8 hours of CIS. Administration of a small molecule AQP4 inhibitor during donor heart collection and storage and for a short-time posttransplantation improves the viability of donor graft cells, diminishes donor-reactive T cell responses, and extends allograft survival in the absence of other immunosuppression. Furthermore, AQP4 inhibition is synergistic with cytotoxic T lymphocyte-associated antigen 4-Ig in prolonging survival of 8-hour CIS heart allografts. AQP4 blockade markedly reduced T cell proliferation and cytokine production in vitro, suggesting that the improved graft survival is at least in part mediated through direct effects on donor-reactive T cells. These results identify AQPs as a promising target for diminishing donor-specific alloreactivity and improving the survival of high-risk organ transplants.
