Scheduling in dual gripper robotic cells for productivity gains (2001)

We consider single part-type problems. Since all parts produced are identical, it is sufficient to determine the sequence of moves performed by the robot. The processing constraints define the cell to be a flowshop. The objective is the minimization of the steady-state cycle time to produce a part, or equivalently the maximization of the throughput rate. We study the problem of scheduling robot moves in dual gripper robot cells functioning in a bufferless environment. We develop an analytical framework for studying dual gripper robotic cells and examine the cycle time advantage of using a dual gripper rather than a single gripper robot. It is shown that an m-machine dual gripper robot cell can have at most double the productivity of its single gripper counterpart. We also propose a practical heuristic algorithm to compare productivity for given cell data. Computational testing of the algorithm on realistic problem instances is also described.
Kinetics of Liquid-Phase Esterification Catalyzed by Acidic Resins (1997)

The characteristics of ion-exchange resins provide the basis for many processes of practical interest involving both sorption separations and catalytic reactions. The optimal design and operation of these processes require a proper understanding of the equilibrium behavior of multicomponent liquid mixtures in contact with cross-linked polymeric resins, in terms of both the amount and composition of the sorbed mixture. For this, a model which describes the equilibrium between a polymer phase, described through the extended Flory−Huggins theory, and a liquid phase, which does not contain the polymer, has been developed. This has then been coupled with a kinetic model describing the catalytic reaction inside the resin particles. The model has been validated through an appropriate experimental analysis involving both equilibrium partitioning and reactive experiments, for the case of a highly cross-linked sulfonated resin in the presence of various mixtures of the components involved in the esterification of ethanol with acetic acid. The results indicate the ability of the resin not only to catalyze the esterification reaction but also to shift the corresponding equilibrium conversion, due to its swelling capability. This approach is believed to apply to a wide class of reactions catalyzed by polymeric resins, and it is suitable for the optimal design of the corresponding processes.

Temperature-Sensitive Pluronic/Poly(ethylenimine) Nanocapsules for Thermally Triggered Disruption of Intracellular Endosomal Compartment (2006)

Pluronic hydrogel nanoparticles cross-linked with poly(ethylenimine) (PEI) were synthesized by a modified emulsification/solvent evaporation method. Pluronic F-127 preactivated at the terminal group with p-nitrophenyl chloroformate was dissolved in dichloromethane, and the organic solution was emulsified in deionized water containing PEI by sonication. Primary amine groups of PEI in the aqueous phase were conjugated and/or cross-linked with activated Pluronic F-127 in the vicinity of the water/dichloromethane interface, resulting in the formation of shell-cross-linked Pluronic/PEI nanocapsules. Pluronic/PEI nanocapsules exhibited a volume transition behavior over a temperature range of 24-33 degrees C. The thermally reversible swelling/deswelling of Pluronic/PEI nanocapsules was caused by temperature-dependent hydrophobic interaction of cross-linked and/or grafted Pluronic polymer chains in the nanocapsules. Pluronic/PEI nanocapsules were utilized to break up intracellular endosomal compartments by swelling-induced destabilization of the endosomal membrane triggered by a cold-shock treatment.
Bis- and tris(amidine)fluoroboron cations and mixed tetrahaloborate anions: NMR studies of mixed boron trihalide adduct redistribution reactions involving amidines as strong nitrogen bases (1996)

Amidines as strong Lewis bases react with amidine–mixed boron trihalide adduct systems D•BF n Cl 3−n (n = 0–3) in the presence of excess boron trihalide to give complex mixtures of products including the mixed tetrahaloborate anions BF n Cl 4−n − and the fluoroboron cations D 2 BF 2 + and D 3 BF 2+ , which coexist with the neutral adducts D•BF n Cl 3−n . Excess amidine rapidly displaces chloride ion from the chlorofluoroborate anions and neutral mixed boron trihalide adducts to give high yields of the fluoroboron cations. The D 3 BF 2+ cations of the amidines 1,8-diazabicyclo[5,4,0]undec-7-ene (DBU) and 1,5-diazabicyclo[4,3,0]non-5-ene (DBN) are inert and have been isolated as their hexafluorophosphate salts. (DBN) 2 BF 2 + is inert and has been isolated as its hexafluorophosphate salt, but (DBU) 2 BF 2 + is highly reactive. Key words: amidines, fluoroboron cations, mixed boron trihalide adducts, redistribution reactions, fluorine-19 NMR, boron-11 NMR, 1,8-diazabicyclo[5,4,0]undec-7-ene (DBU), 1,5-diazabicyclo[4,3,0]non-5-ene (DBN)
Four-Branch Open-Loop Transmit Diversity Based on STBC Group-Coherent Codes for OFDM-CDM Systems (2006)

This letter describes four-branch open-loop transmit diversity schemes that are based on group-coherent codes using space-time block codes (STBC-GCC), for orthogonal frequency-division multiplexing and code-division multiplexing (OFDM-CDM) systems. Open-loop STBC-GCC is designed for transmitting control data by two-dimensional spreading, which is achieved by applying two distinct Walsh-Hadamard (WH) codes within the same mother-code group to two different groups of transmit antennas. The simulation results demonstrated that open-loop STBC-GCC applied to two-dimensional spreading provides space diversity gains and frequency diversity gains. It can therefore be concluded that open-loop STBC-GCC is suitable for transmitting common control data or broadcast data via two-dimensional spreading OFDM-CDM.

The simulation results having been obtained suggest the usefulness of the proposed system.
Room temperature rate constant for the reaction of Na with Cl2 (1986)

The room temperature rate constant for the reaction of atomic sodium with Cl2 is measured to be (6.7±0.9)×10−10 cm3 molecule−1 s−1. This experiment is performed in a fast flow reactor where Na is detected using laser-induced fluorescence. The results of this measurement are compared with simple collision theory.
Borosilicate glass matrix composites reinforced with short metal fibres (1994)

The reinforcement of a borosihcate glass with Hastelloy X short fibres is discussed. A fabrication process consisting of wet mixing of the glass powder and the metallic fibres and hot pressing of the mixtures was developed. Composites containing 15 vol.% fibres homogeneously distributed in a near fully dense glass matrix were obtained. Both Young's modulus and fracture strength increased with increasing volume fraction of fibres. The experimental values for the Young's modulus are in agreement with theoretical predictions. No fibre pull-out during fracture was detected and there is a good interfacial bond. By means of a rule-of-mixture calculation for the fracture energy, a five-fold increase in fracture toughness for composites containing 15 vol.% fibres can be predicted.
A Portable Prompter System Equipped with a Liquid Crystal Display (1990)

Prompter systems have become indispensable for various kinds of news productions. In general, ordinary prompter systems are equipped with cathode ray tube (CRT) monitors. These often cannot be used easily out-of-doors because of their weight and size. A new 12-in. liquid crystal display has been developed that has made possible a remarkably compact prompter system, which has both high operational performance and mobility. This portable prompter has played an important role in many field applications since the summit meeting between the U.S. and the USSR in 1985.
Microarray expression profiling identifies genes, including cytokines, and biofunctions, as diapedesis, associated with a brain metastasis from a papillary thyroid carcinoma. (2016)

Brain metastatic papillary thyroid carcinomas (PTCs) are afflicted with unfavorable prognosis; however, the underlying molecular genetics of these rare metastases are virtually unknown. In this study, we compared whole transcript microarray expression profiles of a <i>BRAF</i> mutant, brain metastasis from a PTC, including its technical replicate (TR), with eight non-brain metastatic PTCs and eight primary brain tumors. The top 95 probe sets (false discovery rate (FDR) <i>p</i>-value < 0.05 and fold change (FC) > 2) that were differentially expressed between the brain metastatic PTC, including the TR, and both, non-brain metastatic PTCs and primary brain tumors were in the vast majority upregulated and comprise, e.g. <i>ROS1</i>, <i>MYBPH</i>, <i>SLC18A3</i>, <i>HP</i>, <i>SAA2-SAA4</i>, <i>CP</i>, <i>CCL20</i>, <i>GFAP</i>, <i>RNU1-120P</i>, <i>DMBT1</i>, <i>XDH</i>, <i>CXCL1</i>, <i>PI3</i>, and <i>NAPSA</i>. Cytokines were represented by 10 members in the top 95 probe sets. Pathway and network analysis (<i>p</i>-value < 0.05 and FC > 2) identified granulocytes adhesion and diapedesis as top canonical pathway. Most significant upstream regulators were lipopolysaccharide, TNF, NKkB (complex), IL1A, and CSF2. Top networks categorized under diseases & functions were entitled migration of cells, cell movement, cell survival, apoptosis, and proliferation of cells. Probe sets that were significantly shared between the brain metastatic PTC, the TR, and primary brain tumors include <i>CASP1</i>, <i>CASP4</i>, <i>C1R</i>, <i>CC2D2B</i>, <i>RNY1P16</i>, <i>WDR72</i>, <i>LRRC2</i>, <i>ZHX2</i>, <i>CITED1</i>, and the noncoding transcript AK128523. Taken together, this study identified a set of candidate genes and biofunctions implicated in, so far nearly uncharacterized, molecular processes of a brain metastasis from a PTC.

COLOR VISION SYSTEM FOR RIPENESS INSPECTION OF OIL PALM ELAEIS GUINEENSIS (2002)

In checking harvesting discipline and quality control for oil palm fruits, color has presumably been an important guide to whether the oil content has reached a maximum where the fruit bunch is ready for cutting. However, establishing a single and harmonious standard base on color is a very contentious issue in the oil palm industry because of the subjective nature of the human vision of color. This was further complicated due to the lack of information on fruit color upon which to base a definite ripeness criterion. We demonstrated in this paper that this problem can be solved using machine vision technology. Methods used were to treat color in HSI (Hue, Saturation and Intensity) color space and applied multivariate discriminant analysis. These have proven to be highly effective for color evaluation and image processing. The vision system was trained to classify oil palms into four quality grades according to PORIM (Palm Oil Research Institute of Malaysia) inspection standards. These are the unripe, the underripe, the optimally ripe and the overripe classes. Depending upon the quality feature evaluated, misclassification by the vision system varied from 5 to 12% but averaged at about 8%. Machine vision disagreement ranged from 2 to 19%.
DNA sequencing and melting curve. (1979)

The dependence of DNA absorbance (for light at about 260 nm) on temperature is related to a specific DNA sequence structure in the vicinity of DNA thermal denaturation (the so-called DNA melting or coiling). A straightforward analysis of the experimental DNA melting curve allows us to determine the lengths, the A+T content, and the location in DNA of certain domains. In the case of a specific DNA fragmentation, the order of fragments in DNA can be learned from this analysis, nondestructively and quickly, without fractionating the fragments and other methods of fragmentation. If the DNA nucleotide sequence is known except for some sites and uncertain portions, the analysis determines these sites and the accuracy of the sequence at the portions. This information may complement exact methods of DNA sequencing. The proposed analysis is applied to bacteriophage phiX174, whose melting curve is known. The results are compared to and found to be in an excellent agreement with the known phiX174 nucleotide sequence.
LiFi Integrated to Power-lines for Smart Illumination Cum Communication (2013)

Visible Light Communication (VLC) system based on white LEDs has emerged as an eco-friendly IT green technology using THz visible light spectrum in provision of both lighting and wireless access. Installation of new communication cables between other fixed network (PC, Set-Top Box, fiber networks, etc.) and LED lights is expensive, disruptive and time consuming process. Meanwhile, the power-line communications (PLC) can make it possible to use the power lines as the medium of communications. The utilities of home networking over power-lines can take advantage of the existing wiring infrastructure for provision of illumination cum communication. The integrated system of VLC and PLC is a smart way of fulfilling the premise of broadband access for home networking, while providing efficient and low-cost lighting. To achieve the higher data rates (MHz), PLC channel is simulated using DMT-QAM modulation scheme.
The region controlling the thermosensitive effect of plasmid Rts1 on host growth is separate from the Rts1 replication region (1981)

Rts1 is a high-molecular-weight (126 x 10(6)) plasmid encoding resistance to kanamycin. It expresses unusual temperature-sensitive phenotypes, which affect plasmid maintenance and replication, as well as host cell growth. We have cloned the essential replication region of Rts1 from pAK8, a smaller derivative which is phenotypically similar to Rts1. Restriction endonuclease digests of isolated pAK8 deoxyribonucleic acid were allowed to "self-ligate" (ligation without an additional cloning vector) and subsequently were used to transform Escherichia coli strain 20SO to kanamycin resistance. Screening of these strains for the phenotypes of thermosensitive host growth and temperature-dependent plasmid elimination demonstrated that these two properties were expressed independently. Furthermore, it was shown that the Rts1 replication locus per se is not necessarily responsible for altered host growth at the nonpermissive temperature. The kanamycin resistance fragment of pAK8 was also cloned into pBR322. Electrophoretic analysis of BamHI restriction enzyme digests of this plasmid and similar digests of an Rts1 miniplasmid has allowed the identification of an 18.6-megadalton fragment carrying the replication locus and a 14.1-megadalton fragment carrying the kanamycin resistance gene.
Theorems of Brion, Lawrence, and Varchenko on rational generating functions for cones (2005)

We discuss and give elementary proofs of results of Brion and of Lawrence-Varchenko on the lattice-point enumerator generating functions for polytopes and cones. This largely expository note contains a new proof of Brion's Formula using irrational decompositions, and a generalization of the Lawrence-Varchenko formula.
Review of Meningococcal Group B Vaccines (2010)

No broadly effective vaccines are available for prevention of group B meningococcal disease, which accounts for >50% of all cases. The group B capsule is an autoantigen and is not a suitable vaccine target. Outer-membrane vesicle vaccines appear to be safe and effective, but serum bactericidal responses in infants are specific for a porin protein, PorA, which is antigenically variable. To broaden protection, outer-membrane vesicle vaccines have been prepared from >1 strain, from mutants with >1 PorA, or from mutants with genetically detoxified endotoxin and overexpressed desirable antigens, such as factor H binding protein. Also, recombinant protein vaccines such as factor H binding protein, given alone or in combination with other antigens, are in late-stage clinical development and may be effective against the majority of group B strains. Thus, the prospects have never been better for developing vaccines for prevention of meningococcal disease, including that caused by group B strains.
A 0.6 V ultra low voltage operational amplifier (2003)

A technique for low-voltage CMOS analog circuit design is presented in this paper. In this technique, voltage sources are added in series with the gates of the MOS transistors to lower the effective threshold voltages of the transistors. With the lowered effective threshold voltage, it is possible to build a host of analog circuit that operates with a decreased supply voltage. A 0.6 V ultra-low voltage two-stage operational amplifier (op amp) was designed in a standard 3.3 V 0.35 /spl mu/m CMOS process to validate the technique. Compared to its counterpart operating with a 3.3 V power supply at a much higher power level, the low-voltage op amp maintained the same gain-bandwidth product and most other key performance parameters.

Diagnosis and Treatment of Chronic Abacterial Prostatitis (2000)

There is no gold-standard diagnostic test for chronic abacterial prostatitis, and the methodologic quality of available studies of diagnostic tests is low. The few treatment trials are methodologically weak and involved small samples. The routine use of antibiotics and alpha-blockers to treat chronic abacterial prostatitis is not supported by the existing evidence.
Nocardia uniformis nom. rev. (1999)

A soil isolate representing the putatively novel species 'Nocardia uniformis' was found to have morphological, staining and chemotaxonomic properties consistent with its classification in the genus Nocardia. An almost complete sequence of the 16S rDNA of the strain was determined following cloning and sequencing of the amplified gene. The sequence was aligned with those available for nocardiae and phylogenetic trees were inferred using four tree-making algorithms. The organism was consistently associated with the type strain of Nocardia otitidiscaviarum albeit with a relatively low bootstrap value recorded for neighbour-joining analysis. The strain was also readily separated from representatives of all validly described Nocardia species using a set of phenotypic properties. The genotypic and phenotypic data indicate that the strain should be assigned to the genus Nocardia as a new species. The name proposed for the new species is Nocardia uniformis. The type strain is JCM 3224T.
Antigenicity of beta-propiolactone-inactivated virus vaccines. (1955)

Summary 1.A simple and rapid procedure for the preparation of inactivated virus vaccine is described using β-propiolactone (BPL), an agent not previously employed in the preparation of vaccines. 2.β-propiolactone is capable of inactivating viruses in 10–15 minutes at 37°C whereas formalin and phenol require days for the same degree of inactivation under parallel conditions. 3.Satisfactory inactivated vaccines can be prepared with eastern equine encephalomyelitis virus, rabies virus and MM-virus with the use of BPL. 4.A significantly higher degree of antigenicity is demonstrated with β-propiolactone-inactivated virus vaccines than with formalin- and phenol-inactivated virus vaccines. 5.Two to four times the minimal effective viricidal concentration of BPL can be used in the preparation of virus vaccines without critical loss in antigenicity.
Multi-Commodity Network Flows (1963)

A network is a set of nodes N ı connected by arcs with nonnegative arc capacities b ıj which indicates the maximum amount of flow that can pass through the arc from N ı to N j . Given all b ıj , there is a maximum flow from N ı to N j using all arcs. Under the assumption that b ıj = b jı , the present paper generalizes the max-flow min-cut theorem of Ford and Fulkerson to the problem of finding the maximum simultaneous flows of two commodities and gives an algorithm similar to the labelling method for constructing the two flows.
Structure Design of Naphthalimide Derivatives: Toward Versatile Photoinitiators for Near-UV/Visible LEDs, 3D Printing, and Water-Soluble Photoinitiating Systems (2015)

Seven naphthalimide derivatives (NDP1–NDP7) with different substituents have been designed as versatile photoinitiators (PIs), and some of them when combined with an iodonium salt (and optionally N-vinylcarbazole) or an amine (and optionally chlorotriazine) are expected to exhibit an enhanced efficiency to initiate the cationic polymerization of epoxides and the free radical polymerization of acrylates under different irradiation sources (i.e., the LED at 385, 395, 405, 455, or 470 nm or the polychromatic visible light from the halogen lamp). Remarkably, some studied naphthalimide derivative based photoinitiating systems (PIS) are even more efficient than the commercial type I photoinitiator bisacylphosphine oxide and the well-known camphorquinone-based systems for cationic or radical photopolymerization. A good efficiency upon a LED projector at 405 nm used in 3D printers is also found: a 3D object can be easily created through an additive process where the final object is constructed by coating down successive layers of material. As another example of their broad potential, a NDP compound enveloped in a cyclodextrin (CD) cavity, leads to a NDP–CD complex which appears as a very efficient water-soluble photoinitiator when combined with methyldiethanol amine to form a hydrogel. The high interest of the present photoinitiator (NDP2) is its very high reactivity, allowing synthesis in water upon LED irradiation as a green way for polymer synthesis.The structure/reactivity/efficiency relationships as well as the photochemical mechanisms associated with the generation of the active species (radicals or cations) are studied by different techniques including steady state photolysis, fluorescence, cyclic voltammetry, laser flash photolysis, and electron spin resonance spin-trapping methods.
