Tandem Vinylogous 1,2-Addition/Anionic Oxy-Cope Reaction Leading from Butadiene Sulfone to an Orthogonally Functionalized Bicycle (2010)

Here we present a transition metal-free synthesis of a rigid, orthogonally functionalized bicyclic sulfone, starting from readily available reagents. The transformation proceeds via a tandem vinylogous 1,2-addition/anionic oxy-Cope sequence, followed by a second vinylogous ketone addition. Stereochemical assignments suggest that the anionic oxy-Cope reaction proceeds exclusively through a boat-shaped transition state. The product of the two-step sequence can be further functionalized through subsequent chemo- and diastereoselective transformations, suggesting possible applications in medicinal chemistry or materials chemistry.

Automatic Annotation and Segmentation of Object Instances With Deep Active Curve Network (2019)

Object instance segmentation is a challenging task in computer vision research, and instance annotation is its key sub-task and a basic component of segmentation models. In this paper, we propose the Deep Active Curve Network (DACN) which combines powerful ResNet models with GCN-based active curves. This new method regards instance segmentation as a points/vertices, edges and object masks prediction task instead of only a pixel-labeling problem. The multi-scale encoder firstly predicts a coarse result through a combination of the edge and segmentation features in a multi-task learning framework, which is effective dealing with objects with rough boundaries. In order to generate an accurate object annotation, an iterative Graph Convolutional Network (GCN) is used to correct the encoder's feature map and move all vertices of the predicted coarse result to the edge of the corresponding ground truth. A novel weighted loss function further estimates the location of points, edges, and segmented areas, and optimizes the annotation results. Finally, we use the improved 5-interpolation Catmull-Rom spline (CRS) algorithm which exploits key points to control the active curves around objects. In the experimental analysis, we demonstrate the effectiveness of our proposed method on three datasets in automatic mode, including Cityscapes, ADE20K and Rooftop. We further show the generalization ability of our approach on two novel cross-domain datasets.
Effects of Heavy Drinking, Binge Drinking, and Family History of Alcoholism on Regional Brain Metabolites (2004)

Community-dwelling HD who are not in alcoholism treatment have brain metabolite changes that are associated with lower brain function and are likely of behavioral significance. Age, FH, and binge drinking modulate brain metabolite abnormalities. Metabolite changes in active HD are less pronounced and present with a different spatial and metabolite pattern than reported in abstinent alcoholics.
Data compression of scanned halftone images (1994)

A new method for coding scanned halftone images is proposed. It is information-lossy, but still preserving the image quality, compression rates of 16-35 have been achieved for a typical test image scanned on a high resolution scanner. The bi-level halftone images are filtered, in phase with the halftone grid, and converted to a gray level representation. A new digital description of (halftone) grids has been developed for this purpose. The gray level values are coded according to a scheme based on states derived from a segmentation of gray values. To enable real-time processing of high resolution scanner output, the coding has been parallelized and implemented on a transputer system. For comparison, the test image was coded using existing (lossless) methods giving compression rates of 2-7. The best of these, a combination of predictive and binary arithmetic coding was modified and optimized achieving a compression rate of 9.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Induced Responses in Phenolic Metabolism in Two Norway Spruce Clones after Wounding and Inoculations with Ophiostoma polonicum, a Bark Beetle-Associated Fungus (1995)

Two Norway spruce (Picea abies Karst.) clones, one resistant and the other susceptible to mass inoculation with Ophiostoma polonicum Siem., were compared with regard to their phenolic compositions and chalcone synthase (CHS) and stilbene synthase activities of their phloem before and at 6 and 12 d after artificial inoculation with sterile malt agar or O. polonicum. In unwounded phloem, the resistant clone differed from the susceptible clone by the presence of taxifolin glycoside, lower concentrations of stilbene glycosides, and higher CHS activity. After inoculation, (+)-catechin concentration and CHS activity dramatically increased around the wound, particularly in the resistant clone. Stilbene synthase activity also increased, but more slowly and to a lower level, whereas the concentrations of stilbenes remained stable. Tanning ability decreased in the susceptible clone, whereas it remained stable in the resistant one. It is proposed that the induced phenolic response of Norway spruce phloem consists of an activation of the phenolic pathway, finally leading to tannins and insoluble polymers. It is suggested that resistance to O. polonicum depends on the ability of the tree to easily activate the flavonoid pathway.

Tamoxifen‐stimulated Growth of Human Endometrial Carcinoma (1991)

An estrogen receptor and progesterone receptor positive endometrial carcinoma (EnCa101) will grow in response to either estradiol or tamoxifen when transplanted into athymic mice. We have tested several antiestrogens with different properties to determine their ability to support endometrial tumor growth. Trioxifene, enclomiphene and nafoxidine are all as active as tamoxifen whereas the antiestrogen keoxifene, that has reduced estrogen-like properties, will partially inhibit tamoxifen-stimulated growth. Furthermore, the pure antiestrogen ICI 164,384 will block tamoxifen-stimulated growth without having any effect itself on tumor growth rate. Overall, the ability of antiestrogens to stimulate the growth of human endometrial carcinoma EnCa101 appears to be related to their intrinsic estrogenic activity.

Base specificity and binding of anti-ss/dsDNA monoclonal antibody. Application to the determination of ssDNA. (1993)

An anti-DNA murine hybridoma was generated and selected in a fusion of Sp2/0 myeloma cells with splenocytes derived from BALB/c mice immunized with DNA/protein complex. The monoclonal antibody designated as 4C7 was assessed by competitive immunoassay for binding to denatured, structurally single-stranded (ss)DNA, double-stranded (ds)DNA and oligodeoxynucleotides. The monoclonal antibody exhibited a marked preference for the ss conformation. Competitive inhibition assay performed with nucleosides and homopolynucleotides indicated that the deoxyadenosine residue was essential for antibody recognition and binding. The monoclonal antibody was purified by poly(A)-Sepharose chromatography and biotinylated. The ssDNA detection limit in the enzyme-linked immunosorbent assay with the biotinylated antibody ranged from 1 to 16 ng/ml. A dot immunobinding test was developed which was sensitive for the quantitation of picogram amounts of single-stranded DNA deposited on nitrocellulose filters and applied to the immunoenzymatic detection in human sera of target DNA.

Interference phase calculation and sample scanning is controlled by a PC computer. Height sensitivity is of the order of 1 nm and lateral resolution is ~10 microm. Results are given which demonstrate the reproducibility and stability of the system.
Homogeneously catalysed conversion of aqueous formaldehyde to H2 and carbonate (2017)

Small organic molecules provide a promising solution for the requirement to store large amounts of hydrogen in a future hydrogen-based energy system. Herein, we report that diolefin-ruthenium complexes containing the chemically and redox non-innocent ligand trop<sub>2</sub>dad catalyse the production of H<sub>2</sub> from formaldehyde and water in the presence of a base. The process involves the catalytic conversion to carbonate salt using aqueous solutions and is the fastest reported for acceptorless formalin dehydrogenation to date. A mechanism supported by density functional theory calculations postulates protonation of a ruthenium hydride to form a low-valent active species, the reversible uptake of dihydrogen by the ligand and active participation of both the ligand and the metal in substrate activation and dihydrogen bond formation.

<i>Bacillus thuringiensis</i> ssp. <i>galleriae</i> simultaneously produces two δ‐endotoxins differing strongly in primary structure and entomocidal activity (1988)

Strain 11–67 of B. thuringiensis ssp. galleriae produces two entomocidal proteins of molecular mass 130 kDa. Limited proteolysis of these proteins — protoxins — yields the ‘true’ toxins of molecular mass 65 kDa which are drastically different with respect to their charges at pH 8.6, immunological properties and toxicity (host range). One of the proteins — the ‘negative’ component — is toxic for Lymantria dispar larvae and shows 65% homology when compared with B. thuringiensis ssp. kurstaki δ‐endotoxins. The other — the ‘positive’ component — is toxic for Galleria mellonella larvae. Its N‐terminal sequence of 11 amino acid residues is homologous with the B. thuringiensis ssp. israelensis and san diego endotoxins known to be toxic for Coleoptera and Diptera but not for Lepidoptera. Hence, B. thuringiensis subspecies may produce simultaneously δ‐endotoxins differing substantially in structural features and host range.
Refractive Index Measurement of Liquids Using A Dual-color Optical Fiber SPR Sensing System (2006)

In this paper we present practical capability of a dual-color optical fiber surface plasmon resonance (SPR) sensing system for measuring the refractive index (RI) of liquids. The sensor system consists of two LEDs, two optical couplers, a photodiode and an electronics followed by a laptop computer via an A/D converter. Features of the developed system are compact, portable and inexpensive. Principle of the proposed SPR sensing system is based on the differential reflectance method. Changes of reflectance at two wavelengths are proportional to the refractive index change of a sensed medium. Differential of two reflectance gives two-folded sensitivity. Three liquids with different RI ranges were tested. Also the reproducibility of measured data was checked. As a result, it was demonstrated experimentally that the dual-color optical fiber SPR sensing system is capable of measuring the RI of liquids over the range of from 1.329 to 1.36 with the RI resolution of 2.35 X 10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-4</sup> .
Binary Multiplication Using Partially Redundant Multiples (1992)

This report presents an extension to Booth&apos;s algorithm for binary multiplication. Most implementations that utilize Booth&apos;s algorithm use the 2 bit version, which reduces the number of partial products required to half that required by a simple add and shift method. Further reduction in the number of partial products can be obtained by using higher order versions of Booth&apos;s algorithm, but it is necessary to generate multiples of one of the operands (such as 3 times an operand) by the use of a carry propagate adder. This carry propagate addition introduces significant delay and additional hardware. The algorithm described in this report produces such difficult multiples in a partially redundant form, using a series of small length adders. These adders operate in parallel with no carries propagating between them. As a result, the delay introduced by multiple generation is minimized and the hardware needed for the multiple generation is also reduced, due to the elimination of expensive ca...
Objective Sleep Quality of Healthy Older Men and Women Is Differentially Disrupted by Nighttime Periodic Blood Sampling via Indwelling Catheter (1996)

Elucidation of sleep-endocrine relationships requires frequent blood sampling during sleep recording. Unfortunately, such sampling can itself affect sleep and indirectly, hormonal patterns. We examined the effect of catheterization and frequent nighttime blood sampling on the sleep of a large sample of healthy older men and women. A total of 113 healthy older [69.1 +/- 0.6 years, mean +/- standard error of the mean (SEM) adults (68 women and 45 men) were studied. Following an adaptation night sleep was recorded during an undisturbed night and a night of periodic blood sampling via i.v. catheter. Lights out and lights on were significantly delayed and advanced, respectively, on the catheterization night, resulting in a significantly shorter time in bed (TIB). Total sleep time and sleep efficiency were significantly reduced, and sleep latency, total wake time and the number of awakenings from sleep of > or = 1 minute were significantly increased. Rapid eye movement (REM) sleep percentage of TIB was significantly reduced. Stages 3/4 sleep [slow wave sleep (SWS)] percentage of TIB was significantly reduced, as was total delta energy during SWS. With the exception of total sleep time and sleep latency, all sleep-wake and delta variables were significantly correlated between nights. This was particularly the case for SWS and the delta energy variables. When examined separately by gender, both men and women showed significant catheter-based sleep disturbance. However, SWS and delta energy measures in men were unaffected by catheterization. The data clearly demonstrate that both the sleep maintenance and sleep architecture of healthy older men and women are significantly impacted by nighttime blood sampling procedures. Of the various measures examined here, SWS measures appear to be the least disrupted, particularly in men. These findings need to be taken into account in any study examining sleep-endocrine relationships utilizing older subjects.
Allocation of distribution system losses to consumers in deregulated electricity supply industries (1996)

Moves towards the deregulation of the electricity supply industry in many parts of the world have led to the introduction of varying degrees of competition in certain sectors of the business. In countries such as the UK, where competition has been extended into the supply side of the business, it has been necessary to distinguish between the costs of energy and the costs of transporting the energy to the consumer. Currently in the UK, nonfranchise customers (whose annual maximum demands exceed 100 kW) may purchase energy from any licensed supplier, paying the local distribution company a `use of system' charge for transmission of the electricity to the point of use. An important element of these use of system tariffs is a table of loss adjustment factors that reflect the percentage by which purchases of energy at entry points to the system must exceed consumption at the point of use to account for the losses which occur in between. Distribution companies are obliged to calculate loss adjustment factors on an individual basis for major consumers, and this has brought about the need for techniques which allocate losses on a more detailed basis than was necessary prior to deregulation. This paper describes a new approach to the evaluation of loss adjustment factors for distribution systems, which combines the use of graph theory with readily available load flow results, to assign the losses in each line or transformer within the system to the consumers supplied by it.

Dielectric metamaterial lens antenna for wide angle beam scanning (2010)

The dielectric metamaterial lens antenna for wide angle beam scanning is discussed as an applicative antenna. The availability of the low-loss structure using dielectric resonator and the cause of the reduction of the antenna efficiency are clarified by the electromagnetic simulations. The validation of the design of the metamaterial lens antenna is clarified through the experiment.
M and Jam Factory (1987)

M (Fig. 1) and Jam Factory (Fig. 2) are the first software packages published by Intelligent Music, a company founded by composer Joel Chadabe to provide a commercial outlet for interactive composing software (Chadabe 1984) and intelligent instruments. M and Jam Factory, commercially available since December 1986, run on Apple Macintosh computers equipped with a MIDI interface (Chadabe and Zicarelli 1986, 1987). Both M and Jam Factory are programs that, through the use of graphic and gestural interfaces, provide an environment for composing and performing with MIDI. The resulting environment, characterized by controls that offer immediate feedback in modifying an ongoing process, is quite analogous to the control panel of an airplane. Indeed, one of the early models for the programs was Fokker Triplane, a flight simulation program for the Macintosh.
