Factors involved in specific transcription by mammalian RNA polymerase II. RNA polymerase II-associating protein 30 is an essential component of transcription factor IIF. (1988)

Transcription from class II promoters requires five general factors, IIA, IIB, IID, IIE, and IIF, in addition to RNA polymerase II for basal levels of transcription (Reinberg, D., Flores, O., and Buckbinder, L. (1987) in Molecular Biology of RNA: New Perspectives (Inouye, M., and Dudock, B., eds) pp. 423-439, Academic Press, Orlando, FL). A protein fraction containing transcription factors (TF) IIE and IIF was able to reconstitute transcription from the adenovirus major late promoter when added to extracts depleted of the RNA polymerase II-associating proteins RAP 30 and RAP 74 (Sopta, M., Carthew, R.W., and Greenblatt, J. (1985) J. Biol. Chem. 260, 10353-10360). Studies with monoaffinity-purified antibodies directed against RAP 30 demonstrated, by Western blot analysis, that RAP 30 copurifies on five columns with transcription factor IIF. That RAP 30 is a functional component of TFIIF was also demonstrated; preincubation of anti-RAP 30 antibodies with purified TFIIF inhibited transcription. Inhibition of transcription was overcome by the addition of purified TFIIF. RAP 30 is an integral part of a preinitiation complex; the incubation of all the general transcription factors with a promoter-containing DNA, prior to the addition of the anti-RAP 30 antibodies, resulted in the formation of a DNA-protein complex that was not inhibited by the antibodies. Incubation of the transcription factors in the absence of a promoter-containing DNA resulted in a complex that was partially resistant to the antibodies.
The Estimation of Phosphine in Air (1963)

Abstract A simple field method has been developed for the estimation of phosphine in the atmosphere of grain silos and other fumigation areas. The procedure uses silver nitrate impregnated papers as a means of visual detection. Quantitative estimation as low as 0.05 ppm is by color comparison with standard stains. Confirmatory analysis is by determination of reduced silver as the sulfide.
Fluoresence Studies of Nucleotides and Polynucleotides (1972)

Diphosphopyridine nucleotide analogues have been prepared in which the adenosine 5′-monophosphate of the coenzyme is replaced by the 5′-monophosphate of one of the following fluorescent nucleosides: formycin, 2-aminopurine riboside, and 7-deazapurine riboside (7-deazanebularin). The analogue compounds, unlike the parent coenzyme, are highly fluorescent in both oxidized and reduced form. Their spectral and fluorescence properties have been examined as a function of temperature, pH, and solvent conditions. All three analogues show significant coenzyme activity and can replace DPN with all of the five dehydrogenases tested; the efficiency of the analogues in these tests is in the range of 20 to 150%, compared with DPN+ itself.
Electron emission from PLZT ceramics induced by polarization switching (1999)

Abstract Electron emission from ferroelectrics has attracted much interest recently. However, a diverse array of results and explanations have appeared due to experimental technique and sample variation. Two different compositions in the PLZT system, which have similar dielectric constant but different hysteretic behavior, were chosen for our study under the same experimental conditions: ferroelectric 8/65/35 and nonferroelectric 15/65/35. Strong electron emission was observed from PLZT 8/65/35, however, the emission intensity degraded rapidly due to electrode destruction. Comparatively, no emission signal was detected from 15/65/35, which can be interpreted as evidence that electron emission from the 8/65/35 ceramics was not the so-called “metaldielectric” emission. Other results and SEM micrographs also suggest that the dominant source of electron emission is due to ferroelectric emission, and not due to plasma effects.
Facile Synthesis of Amine-Terminated Aromatic Polyamide Dendrimers via a Divergent Method (2007)

[structure: see text]. A novel, rapid, inexpensive, and highly efficient divergent approach for the synthesis of a 32-amine-terminated G4 polyamide dendrimer has been developed. Each generation dendrimer was successfully obtained by the condensation of the preceding generation dendrimer with the building block and the deprotection with hydrazine in one pot. All the dendrimers were easily purified by precipitation in alkaline water, and the purity was confirmed by NMR, MALDI-TOF mass spectra, and elemental analysis.
On the Multiplexing Gain of MIMO Phase Noise Channels. (2016)

The capacity of a point-to-point multi-input-multiple-output (MIMO) channel with phase uncertainty (MIMO phase noise channel) is still open. As a matter of fact, even the pre-log (multiplexing gain) of the capacity in the high signal-to-noise ratio (SNR) regime is unknown in general. We make some progresses in this direction for two classes of such channels. With phase noise on the individual paths of the channel (model A), we show that the multiplexing gain is 1/2, which implies that the capacity does not scale with the channel dimension at high SNR. With phase noise at both the input and output of the channel (model B), the multiplexing gain is upper-bounded by 1/2 min{nt,(nr-2)^+ + 1}, and lower-bounded by 1/2 min{nt, floor((nr+1)/2)}, where nt and nr are the number of transmit and receive antennas, respectively. The multiplexing gain is enhanced to 1/2 min{nt,nr} without receive phase noise, and to 1/2 min{2nt-1,nr} without transmit phase noise. In all the cases of model B, the multiplexing gain scales linearly with min{nt,nr}. Our main results rely on the derivation of non-trivial upper and lower bounds on the capacity of such channels.
Location Model for Clustering Location Information in Positioning System (2007)

Everywhere in the Earth, We get a GPS signal from satellite in space. In indoors, we can use indoor position system to get the signal. Its signal format and type are different each other. Therefore, some studies try to mapping information through metadata. However, it's to hard to fix the standard among the heterogynous standards and searching the data through metadata transformations. In this paper, we propose a location model (LM) to describe purpose, place, time and who that are elements of LM. A multimedia data created by device as digital camera, has a variety of metadata. We assume that it has a location metadata as latitude and longitude. We have been clustering location information based on Location Model by LM manager. Moreover, we implements LM Searcher helps user to search correct files. This study shows efficient use of clustering location model and tool of managing and searching among multimedia data in storage system.
NEW VISUALIZATION MODES FOR EFFECTIVE IMAGE PRESENTATION (2009)

In this paper we consider the problem of effective browsing of collections of images. In particular, we address those situations where it is necessary to find a limited number of images satisfying certain criteria, as well as the very common case in which the user, not having a clear idea about what to search, needs to explore the entire picture database to identify what he or she simply likes. The approaches we propose try to find good trade-offs between browsing time and quality of the exploration. The article has a twofold purpose: on the one hand, it presents a selection of the new image display methods we have developed in the last years, which differentiate from those considered to date by the Information Visualization community; on the other hand, it illustrates the results obtained through comparative tests performed on a subset of the developed display modes, with the main aim to prove the feasibility of their use as substitutes for the usual "grid" arrangement.
Exo- and Endocyclic Oxazolinyl−Phosphane Palladium Complexes:  Catalytic Behavior in Allylic Alkylation Processes (2004)

The new bidentate chiral N,P-donor oxazolinyl−phosphane ligands 7−15 are described. Upon coordination to the palladium metal, ligands 7−12 gave endocyclic oxazolinyl−phosphane complexes having seven-membered rings, while ligands 13−15 afforded exocyclic oxazolinyl−phosphinite complexes with six-membered rings, depending on the relative CN oxazoline bond and metal ring position. Ionic palladium(II) complexes containing N,P-bidentate ligands and allyl groups (η3-C3H5 for 16−22 and η3-1,3-Ph2-C3H3 for 23−26) were prepared and fully characterized. X-ray structures were determined for complexes 18 and 19. Pd catalytic systems containing ligands 7−15 were tested in the asymmetric allylic alkylation of the racemic substrates rac-3-acetoxy-1,3-diphenyl-1-propene (I) and rac-3-acetoxy-1-cyclohexene (III). The endocyclic systems show better activites and selectivites (ee values up to 82%) than the exocyclic ones (ee values up to 72%) for substrate I. In particular, palladium endocyclic oxazoline−phosphinite systems containing the PCy2 group (20, 21) give the highest activities, but the best enantioselectivities were observed for those containing PPh2 (18, 19).
System-level design exploration for 3-D stacked memory architectures (2011)

Traditional technology scaling of semiconductor chips followed Moore's Law. However, the transistor performance improvement will be limited, and designer will not see doubling of frequency every two years. Recently, three-dimension integrated circuits (3-D IC) that employ the vertically through-silicon vias (TSVs) for connecting each of dies have been proposed. It is an alternative solution to existent Package-on-Package (PoP) and System-in-Package (SiP) processes. There are many benefits by using TSV-based 3-D integration technologies: (1) more functionality can be integrated into a small silicon space for form factor reduction, (2) circuit delay can be improved by using TSVs due to the shorter interconnect and reduced parasitic capacitance/inductance, (3) different components with incompatible manufacturing process (i.e. Logic, DRAM, Flash, etc) can be combined in single 3-D IC for heterogeneous integration. In addition, there are many 3-D multi-core or many-core architectures are discussed recently. Comparing with traditional two-dimension multi-core or many-core architectures, the major difference is memory bandwidth problem can be addressed by stacked memory architecture. Intel has good demonstration through the teraflops microprocessor chip which is an 80-core design with memory-on-logic architecture. And, each core connects to a 256KB SRAM with 12GB/s bandwidth.

Defining the lipidome of Arabidopsis leaf mitochondria: Specific lipid complement and lipid biosynthesis capacity (2022)

Summary Mitochondria are often considered the power stations of the cell, playing critical roles in various biological processes such as cellular respiration, photosynthesis, stress responses and programmed cell death. To maintain the structural and functional integrities of mitochondria, it is crucial to achieve a defined membrane lipid composition between different lipid classes wherein specific proportions of individual lipid species are present. Although mitochondria are capable of self-synthesizing a few lipid classes, many phospholipids are synthesized in the endoplasmic reticulum and transferred to mitochondria via membrane contact sites, as mitochondria are excluded from the vesicular transportation pathway. However, knowledge on the capability of lipid biosynthesis in mitochondria and the precise mechanism of maintaining the homeostasis of mitochondrial lipids is still scarce. Here we describe the lipidome of mitochondria isolated from Arabidopsis leaves, including the molecular species of glycerolipids, sphingolipids and sterols to depict the lipid landscape of mitochondrial membranes. In addition, we define proteins involved in lipid metabolism by proteomic analysis and compare our data with mitochondria from cell cultures since they still serve as model system. Proteins putatively localized to the membrane contact sites are proposed based on the proteomic results and online databases. Collectively, our results suggest that leaf mitochondria are capable - with the assistance of membrane contact site-localised proteins - of generating several lipid classes including phosphatidylethanolamines, cardiolipins, diacylgalactosylglycerols and free sterols. We anticipate our work to be a foundation to further investigate the functional roles of lipids and their involvement in biochemical reactions in plant mitochondria. One sentence summary The lipid landscape of plant mitochondria suggests that they are capable in generating several phospholipid classes with the assistant of membrane contact site-localized proteins.

Effect of Branch Length on 13C NMR Relaxation Properties in Molten Poly[ethylene‐co‐(α‐olefin)] Model Systems (2007)

Abstract The potential of branch length discrimination for branches containing six and more carbons via bulk NMR relaxation properties in the melt‐state has been explored. A systematic increase in the 13 C spin‐lattice relaxation time ( T ) of the terminal branch carbons 1 and 2 was observed when the branch increased from 6 to 16 carbons in length. The measurement of T via inversion recovery at high‐field showed the most reliable data. The effects of saturation and NOE were addressed by using recycle delays longer than 5 × T and the use of the saturation recovery was found to be unsatisfactory. All nuclear relaxation times were determined in a highly time efficient manner using a previously developed melt‐state MAS NMR method. magnified image
Laser Ablation of Cutaneous Leg Veins (2008)

Patients presenting with lower-extremity telangiectasias, commonly known as spider veins, are a frequent presentation for vascular surgeons. The use of lasers in the treatment of lower-extremity spider veins has gained increased popularity during the past 5 years. This technology, driven by consumer demand, has been effective in treating vessels that are refractory to sclerotherapy treatment, vessels that arise from telangiectatic matting, and in patients who experience a phobia to needles. One laser wavelength per machine limits what the practitioner can do. That is, each type of vein responds best to a specific wavelength. Light skin is more forgiving to complications than dark skin. The devices are a complement to good sclerotherapy, not a substitute.
Parallel-decomposition algorithm for discrete computational problems and its application in developing an efficient discrete convolution algorithm (1995)

The authors present a parallel-decomposition algorithm for discrete computational problems. An efficient convolution algorithm is developed under the proposed decomposition algorithm. The decomposition operation is based on integer modular arithmetic. Congruent sets are generated from integer modular operation over the index of the problem and constitute a partition. The partition is used to decompose the problem into several small subproblems. The partition under the integer modular operation is unique. Complete reconstruction of the problem is guaranteed by the uniqueness of the partition. Since the algorithm is established on the foundation of all algebraic systems, i.e. number and set theories, it is highly problem-independent, and provides an uniform approach to parallel decomposition of general problems on the discrete domain. Because the subproblems are highly regular, it is suitable for VLSI hardware implementation. The computational complexity of the developed convolution algorithm is reduced by a factor of p2, and (p2)n for n-dimensional problems (p can be any common factor of the input sequences). Compared to the popular FFT methods, where round-off error is introduced, the convolution result from the algorithm is exact. In addition, it does not have restrictions on the length of the input sequences, as in the well known block convolution algorithm. As a result, the algorithm is highly efficient for convolution of large input sequences or correlation operations.
Research on balance control for ship roll stability based on transferring liquid among water cabins (2010)

This paper focuses on the ship roll balance control based on the ship roll dynamic model and special actuator. According to the ship dynamics model for roll stability and an actuator with the transferring liquid among Water cabins for ship, a control model for ship roll balance adjustment is built and also the control system is designed. And then, the ship balance performance and dynamic balance process based on the control model are investigated and analyzed with calculation and system simulation. In order to validate the system model built in the paper reasonable, a real case of ship is involved. Two kinds typical cases are employed so as to analysis the control performance. The research result shows it is significant to instruct and control the adjustment process of ship roll balance based on the control model. It can be applied to improve the ship safety and decrease the risk when the ship roll balance is damaged.
Driving high quantum yield NIR emission through proquinoidal linkage motifs in conjugated supermolecular arrays (2020)

High quantum yield NIR fluorophores are rare. Factors that drive low emission quantum yields at long wavelength include the facts that radiative rate constants increase proportional to the cube of the emission energy, while nonradiative rate constants increase in an approximately exponentially with decreasing S<sub>0</sub>-S<sub>1</sub> energy gaps (in accordance with the energy gap law). This work demonstrates how the proquinoidal BTD building blocks can be utilized to minimize the extent of excited-state structural relaxation relative to the ground-state conformation in highly conjugated porphyrin oligomers, and shows that 4-ethynylbenzo[<i>c</i>][1,2,5]thiadiazole (<b>E-BTD</b>) units that terminate <i>meso</i>-to-<i>meso</i> ethyne-bridged (porphinato)zinc (<b>PZnn</b>) arrays, and 4,7-diethynylbenzo[<i>c</i>][1,2,5]thiadiazole (<b>E-BTD-E</b>) spacers that are integrated into the backbone of these compositions, elucidate new classes of impressive NIR fluorophores. We report the syntheses, electronic structural properties, and emissive characteristics of neoteric <b>PZn-(BTD-PZn)n</b>, <b>PZn2-(BTD-PZn2)n</b>, and <b>BTD-PZnn-BTD</b> fluorophores. Absolute fluorescence quantum yield (<i>ϕ</i> <sub>f</sub>) measurements, acquired using a calibrated integrating-sphere-based measurement system, demonstrate that these supermolecules display extraordinary <i>ϕ</i> <sub>f</sub> values that range from 10-25% in THF solvent, and between 28-36% in toluene solvent over the 700-900 nm window of the NIR. These studies underscore how the regulation of proquinoidal conjugation motifs can be exploited to drive excited-state dynamical properties important for high quantum yield long-wavelength fluorescence emission.
Facile Synthesis of Pentaphenylnickelocene and Other Pentaphenylcyclopentadienylnickel and ‐cobalt Complexes (1986)

Glucose Controls the Expression of Polypyrimidine Tract-Binding Protein 1 via the Insulin Receptor Signaling Pathway in Pancreatic β Cells. (2018)

In pancreatic β cells, glucose stimulates the biosynthesis of insulin at transcriptional and post-transcriptional levels. The RNA-binding protein, polypyrimidine tract-binding protein 1 (PTBP1), also named hnRNP I, acts as a critical mediator of insulin biosynthesis through binding to the pyrimidine-rich region in the 3'-untranslated region (UTR) of insulin mRNA. However, the underlying mechanism that regulates its expression in β cells is unclear. Here, we report that glucose induces the expression of PTBP1 via the insulin receptor (IR) signaling pathway in β cells. PTBP1 is present in β cells of both mouse and monkey, where its levels are increased by glucose and insulin, but not by insulin-like growth factor 1. PTBP1 levels in immortalized β cells established from wild-type (βIRWT) mice are higher than levels in β cells established from IR-null (βIRKO) mice, and ectopic re-expression of IR-WT in βIRKO cells restored PTBP1 levels. However, PTBP1 levels were not altered in βIRKO cells transfected with IR-3YA, in which the Tyr1158/1162/1163 residues are substituted with Ala. Consistently, treatment with glucose or insulin elevated PTBP1 levels in βIRWT cells, but not in βIRKO cells. In addition, silencing Akt significantly lowered PTBP1 levels. Thus, our results identify insulin as a pivotal mediator of glucose-induced PTBP1 expression in pancreatic β cells.
Depressor and regionally‐selective vasodilator effects of human and rat urotensin II in conscious rats (2001)

The regional haemodynamic effects of rat or human urotensin II (U-II) 3, 30, 300 and 3000 pmol kg(-1), i.v.) were assessed in separate groups of conscious, unrestrained, male, Sprague-Dawley rats (n=8 in each). Rat and human U-II had similar effects. At a dose of 3 pmol kg(-1), neither peptide had any significant action, while at a dose of 30 pmol kg(-1), there was a transient mesenteric vasodilatation (significant only for rat U-II). At doses of 300 and 3000 pmol kg(-1), there were dose-dependent tachycardias, and mesenteric and hindquarters hyperaemic vasodilatations. Thus, in conscious rats, the predominant cardiovascular action of rat and human U-II is vasodilatation. This is in contrast to recent findings with human U-II in non-human primates, but is consistent with effects on human isolated resistance vessels.
