Efficient multicasting technique for elastic optical network (2020)

Abstract The elastic optical network (EON) is the latest solution to increase the capacity of optical networks, as a response to the ever‐increasing demand for traffic. To meet the EON mission, new algorithms and frameworks need to be designed. In this paper, a new algorithm based on EON is proposed that employs a subtree‐based scheme to establish multicast transmissions. To solve the problems of routing, modulation level and spectrum allocation, the primary problem of EON with regard to resource allocation under wavelength continuity and wavelength contiguity constraints, as well as distance adaptive transmission, the proposed algorithm solves each subproblem by considering the existence of a solution for other subproblems. The authors take into account the effects of splitting the transient light at the intermediary nodes on the signal‐to‐noise ratio to enhance the accuracy of the resource allocation. The proposed scheme is extensively examined under different networks and compared with the existing multicasting benchmark. The simulation results show that the proposed scheme considerably increases the network capacity without placing any burden on the network.
Enhanced catalysts for hydrodenitrogenation of coal liquids: Appendix A (1987)

Two approaches to the development of improved HDN catalysts are being investigated. One approach is to synthesize high-activity, highly dispersed, ''surface-confined'' catalysts based on organometallic cluster complexes. The second approach is to examine the hydrotreating activities of metals not currently used in HDN and HDO catalysis. This second method arises from homogeneous modeling studies for the transalkylation reaction and from studies of bulk metals on the HDN of tetrahydroquinoline. From the results of these studies the investigators have found that ruthenium exhibits the highest activity for C-N bond cleavage. In this paper the syntheses and HDN activities of catalysts prepared using these two approaches are described. The conclusion is that both surface-confining techniques and metal-promotion with an active amine transalkylation catalyst such as Ru/sub 3/(CO)/sub 12/ greatly enhances the activity of CoMo or NiMo HDN catalysts. Not only are the activities of the RuCoMo and RuNiMo catalysts greater, but also the selectivity towards aromatic products are higher. Furthermore, unlike with bulk metals, these ruthenium promoted catalysts are sulfur tolerant. The exact mechanism of the promotion will require more detailed work. However, these preliminary results are highly significant with regard to the need to develop improved HDN catalysts that can removemore » nitrogen with a minimum amount of hydrogen consumption. 6 refs., 1 fig., 1 tab.« less
VISUAL INSPECTION OF AGRICULTURAL PRODUCTS MOVING ALONG SORTING CONVEYORS (1990)

ABSTRACT Two methods of presenting product for visual inspection were compared by measuring the accuracy of the decision process. Simulated products (plastic balls) with random defects were video taped from two different directions (side-to-side and moving toward the inspector). Fifty subjects that viewed the tapes had a 23% increase in their decision accuracy when the product was moving toward them compared to side-to-side. Slow motion analysis of the tape showed that 15% more defects were visible from the end than from the side. The difference between the performance of the inspectors and the actual increase in defects visible to them indicated that ergonomic principles raised the accuracy of the decision process by eight percentage points. Results from an equation developed for calculating the visible surface area of the balls compared favorably with the number of defects visible (13% compared to 15% improvement).
First Self-Consistent Thermal Device Simulator (2010)

We address the most critical issue in nano devices: degradation due to lattice heating. We give recommendations on the lattice heating for different generations of FD SOI devices ranging between 25 nm and 100 nm channel length. We find that in small devices, due to the velocity overshoot effect lattice heating has less degrading effect on the device electrical characteristics. Silicon on diamond is found to be a better device structure in terms of heat transport. We also consider alternative device technologies, such as dual gate devices and find that lattice heating does not have that much degrading effect compared to the current enhancement that these structures offer.
Gulf HDS (hydrodesulfurization) horizons (1980)

The application of the Gulf residual HDS process alone and in combination with residue fluid catalytic cracking (FCC) was studied with Kuwait and Lloydminster crudes of 30.3/sup 0/ and 15.7/sup 0/ API, sulfur contents of 2.9 and 3.6%, and combined nickel and vanadium contents of 35 and 200 ppm, respectively. At high severity, residue yields were 82.4 and 87.4% from the Kuwait and Lloydminster feedstocks, respectively; hydrogen consumption was 1.4 and 1.5%, respectively; product sulfur contents were 0.1 and 0.2%, respectively; and product nickel plus vanadium contents were 1 and 10 ppm, respectively; and investment requirements for a 50,000 bbl/day unit were $130 and $140 million, respectively. An optimization based on the improved FCC product yields and quality possible with HDS pretreatment of the FCC feed and the operating and investment costs of the two processes showed maximum return on investment when the FCC feed contained 5-10 ppm or 15 ppm nickel plus vanadium based on Kuwait and Lloydminster atmospheric residue, respectively, corresponding to HDS at moderate severity.
Growth of Lettuce, Spinach, Mustard, and Wheat Plants under Four Combinations of High-pressure Sodium, Metal Halide, and Tungsten Halogen Lamps at Equal PPFD (1983)

Abstract Plants of lettuce ( Lactuca sativa L. cv. Grand Rapids), spinach ( Spinacia oleracea cv. Bouquet), white mustard ( Sinapis alba L.), and wheat ( Triticum aestivum L. cv. Karamu) were grown at 2 photosynthetic photon flux densities (PPFD 400 to 700 nm at 320 and 700 μmol s −1 m −2 under 4 lamp treatments: metal halide lamps alone, high-pressure sodium lamps alone, metal halide plus tungsten halogen lamps (ca. 1:1 installed wattage), and metal halide plus high-pressure sodium lamps (ca. 1:1 installed wattage). Plants of all species grew well under all treatments and no growth abnormalities were apparent at harvest. It is concluded that dry-weight increase was determined by PPFD and not by spectral irradiance. However, lettuce, spinach, and mustard hypocotyl elongation was greater in young plants grown under the high-pressure sodium lamps in comparison with those grown under the metal halide or metal halide plus tungsten halogen treatments. A strong negative relationship between hypocotyl length and blue photon flux density (400–495 nm) was demonstrated. Anthesis of wheat occurred at the same time under all lamp treatments, but anthesis of mustard differed by 2 days at the higher PPFD and 4 days at the lower PPFD among lamp treatments. The time of anthesis for mustard was found to be weakly but positively correlated with the calculated phytochrome photoequilibrium. Chlorophyll concentrations in young lettuce and spinach plants growing under the high-pressure sodium lamps were 55% and 26% lower, respectively, than those in plants growing under metal halide lamps at the high PPFD level. However, final dry weight was unaffected by any of these morphological differences in the early growth stages.
Effect of Systemic Candidiasis on Blastogenesis of Lymphocytes from Germfree and Conventional Rats (1978)

Germfree and conventional rats were challenged (intravenously) with Candida albicans and sacrificed at various times after infection, and their spleen cells were harvested to examine the effect of disseminated candidiasis on in vitro lymphocyte hypersensitivity to Candida antigens (CA). Results showed that conventional rat splenocytes, initially responsive in vitro to stimulation by CA, manifested a depression in CA-specific responsiveness after challenge with viable C. albicans (days 3 to 6 postchallenge). In addition, the latter splenocyte response to phytohemagglutinin (PHA) and concanavalin A (ConA) was suppressed by 3 to 6 days after challenge with Candida. In contrast to conventional rats, the response of germfree rat splenocytes to CA was insignificant before challenge with C. albicans, and it was increased at 9 days after infection. The response of uninfected germfree rat splenocytes to PHA and ConA was significantly lower than that of unchallenged conventional rats. Challenge with viable C. albicans did not result in a suppression of gnotobiotic rat splenocyte responses to PHA and ConA, but rather, the disseminated infection resulted in as much as fivefold increases in PHA or ConA-induced blastogenesis. These findings suggest that disseminated candidiasis is capable of suppressing blastogenesis in immunologically mature conventional rats and of improving lymphocyte blastogenesis from immunologically immature germfree rats.
Lateral and Transmembrane Redistribution of Tissue-Specific Antigens in Single Cells and Monolayers (1979)

Tissue-specific antigens in the membranes of corneal endothelial cells react with anti-tissue antibodies only in metabolically active monolayers and dispersed cells. After metabolic inhibition by exposure of these preparations to cold, the antigen-antibody complexes, like free antigens, undergo transmembrane redistribution leading to their internalization by the cells. This transmembrane redistribution is reversible and can be followed by using fluorescein-labeled antibodies. Reexpression of the complexes on the cell surfaces occurs after return from metabolic inhibition to metabolic activity. Dispersed corneal endothelial cells are also capable of lateral redistribution (capping) of the complexes although cells in monolayers do not share this capability. Capping in the dispersed cells occurs only at ambient temperatures and, because it results in shedding of the complexes, is irreversible. The data indicate that macromolecules in the membranes of cells organized in tissues are restricted in their movement as compared to the macromolecules of cells functioning in a dispersed state.
Ivermectin and Milbemycin Oxime in Experimental Adult Heartworm ( <i>Dirofilaria immitis</i> ) Infection of Dogs (2010)

Two currently approved macrocyclic lactone HW preventives used at their labeled dose rates were <100% effective against a recent HW field isolate, supporting the hypothesis that the effectiveness of a single dose of these preventives can vary. This is important in guiding clients on expectations of product effectiveness.
Boeing’s Wire Bundle Assembly Project (2001)

This chapter is a history, not a standard scientific report. It tells the story of an industrial research and development project in Augmented Reality (AR)—the Boeing project aimed at using AR to guide the assembly of electrical wire bundles. It describes the goal of the project, the technical approaches we chose, some of the problems and surprises we encountered along the way, and some of the lessons we learned in trying to bring a new computing technology into the world’s largest factory.
Comparaison des performances diagnostiques des protéines IP10 et CXCL9 urinaires pour le diagnostic du rejet aigu du greffon rénal (2014)

Les chimiokines urinaires CXCL9 et IP10 sont de bons candidats pour le diagnostic non invasif du rejet aigu (RA) du greffon rénal. Nous avons comparé les performances diagnostiques de ces 2 molécules, rapportées ou non à la créatininurie (Cr u) , pour le diagnostic du RA clinique. Entre 02/2011 et 01/2013, tous les patients transplantés rénaux ayant eu une biopsie (Bx) pour cause du greffon couplée à un prélèvement urinaire ont été inclus. Les données histologiques des Bx informatives ont été corrélées aux dosages de CXCL9 et CXCL10 par méthode Elisa dans les surnageants urinaires. Au total, 365 Bx issues de 287 patients (58 % d’hommes, 46 ± 16 ans) ont été réalisées 2,9 ± 4,4 ans après la greffe. Le motif de la Bx était : dysfonction du greffon (65 %), protéinurie (12 %), DSA de novo (3 %), réévaluation après traitement (19 %). À la Bx, la créatinine était de 208 ± 130 μmol/L et 31 % avaient des DSA. Cinquante-trois Bx montraient des lésions non spécifiques (14,5 %), 185 une FI/AT (50,7 %), 76 un RA humoral (20,8 %), 22 (6 %) des lésions Borderline, 14 un RA cellulaire (3,8 %), 12 (3,3 %) un RA mixte et 3 une néphrite à BK virus (BKVN). IP10 et CXCL9, rapportés ou non à la Cr u , étaient très significativement augmentés en cas de RA (cellulaire et/ou humoral) par rapport aux autres diagnostics, en excluant les 3 BKVN (18,7 vs 7,8 ng/mmol pour IP10/Cr u , p < 0,0001). La normalisation par la Cr u améliorait significativement la performance diagnostique d’IP10 ( p < 0,05). Le test le plus performant était IP10/Cr u (AUC = 0,73, p < 0,0001). Un seuil de positivité de 5,7 ng/mmol était associé à une sensibilité de 65 % et une spécificité de 71 %. Ces différents biomarqueurs ont des performances diagnostiques similaires pour le diagnostic de RA. La normalisation d’IP10 à la Cr u améliore significativement sa performance diagnostique.
SENSITIVE ASSAY METHOD FOR ACTH USING AN INCREASE IN SECRETION RATE OF ADRENAL VENOUS CORTICOSTERONE IN HYPOPHYSECTOMIZED RATS OF WISTAR STRAIN (1965)

of ACTH in biological fluid the assay method to be used must be highly sensitive as well as specific to this trophic hormone. LIPSCOMB and NELSON described an excellent method to detect a minor amount of ACTH by measuring corticosterone concentration in adrenal venous blood of hypophysectomized rats1). GIRARD and VANCE modified this method and reported that the sensitivity could be further increased by injecting the material into the abdominal aorta at the level of the adrenal artery and one assay rat would be injected several doses of standard and unknown making it possible to calculate the potency of unknown in one rat2). However, the difference of strain and condition in which animals are raised may likely result in different response patterns to exogenous ACTH even if an assay method of identical design is used. The present paper is dealt with the study on the pattern of adrenal corticosterone secretion following intravenous administrations of ACTH U. S. P. and also describes a sensitive method for ACTH using female rats of Wistar strain which are the most commonly used in Japan.
Optimal and Distributed Scheduling for (2008)

We address the problem of multicell co-channel scheduling in view of mitigating interference in a wireless data network with full spectrum reuse. The centralized joint multicell scheduling optimization problem, based on the complete co- channel gain information, has so far been justly considered impractical due to complexity and real-time cell-to-cell signaling overhead. However, we expose here the following remarkable result for a large network with a standard power control policy: The capacity maximizing joint multicell scheduling problem ad- mits a simple and fully distributed solution! This result is proved analytically for an idealized network. From the constructive proof, we propose a practical algorithm that is shown to achieve near maximum capacity for realistic cases of simulated networks of even small sizes.
Expression and disruption of the <i>Arabidopsis TOR</i> (target of rapamycin) gene (2002)

TOR (target of rapamycin) protein kinases were identified in yeasts, mammals, and Drosophila as central controllers of cell growth in response to nutrient and growth factors. Here we show that Arabidopsis thaliana possesses a single TOR gene encoding a protein able to complex with yeast 12-kDa FK506-binding protein and rapamycin despite the insensitivity of Arabidopsis vegetative growth to rapamycin. Analysis of two T-DNA insertion mutants shows that disruption of AtTOR leads to the premature arrest of endosperm and embryo development. A T-DNA-mediated translational fusion of AtTOR with the GUS reporter gene allows us to show that AtTOR is expressed in primary meristem, embryo, and endosperm, but not in differentiated cells. The implications of these features for the plant TOR pathway are discussed.
Syntheses and Applications of Fe-, Co-, Ni- and Cu-Based Bulk Glassy Alloys (2007)

This paper reviews our recent results of the formation, fundamental properties, workability and applications of late transition metal (LTM) base bulk glassy alloys (BGAs) developed since 1995. The BGAs were obtained in Fe-(Al,Ga)-(P,C,B,Si), Fe-(Cr,Mo)-(C,B), Fe-(Zr,Hf,Nb,Ta)-B, Fe-Ln-B(Ln=lanthanide metal), Fe-B-Si-Nb and Fe-Nd-Al for Fe-based alloys, Co-(Ta,Mo)-B and Co-B-Si-Nb for Co-based alloys, Ni-Nb-(Ti,Zr)-(Co,Ni) for Ni-based alloys, and Cu-Ti-(Zr,Hf), Cu-Al-(Zr,Hf), Cu-Ti-(Zr,Hf)-(Ni,Co) and Cu-Al-(Zr,Hf)-(Ag,Pd) for Cu-based alloys. These BGAs exhibit useful properties of high mechanical strength, large elastic elongation and high corrosion resistance. In addition, Fe- and Co-based glassy alloys have good soft magnetic properties which cannot be obtained for amorphous and crystalline type magnetic alloys. The Feand Ni-based BGAs have already been used in some application fields. These LTM base BGAs are promising as new metallic engineering materials.
A Method for the Continuous Recording of Gastric <i>p</i> H in Situ (1939)

A method for continuous recording of gastric acidity is described which consists in the introduction into the stomach of the dog of a glass electrode connected with a pH meter and a recording potentiometer. Adequate mixing of the gastric contents is accomplished by the use of an automatic aspirating and injecting device. This method is suggested as a means of studying the effect of drugs and food in normal animals and those in an induced hypersecretory state. Its clinical applications will be reported later.
Service-Oriented Mediation with jETI/jABC: Verification and Export (2007)

The paper presents how we solved the mediation challenge in a model driven, service oriented fashion, how we verify properties of the mediator via model checking in the jABC, and how to systematically export jABC/jETI orchestrated services as Web services. Due to the lack of maturity of the involved environments and external components, the latter task is less easy and the solutions possible today are less stable than one would expect from these technologies.

The Measurement of Oil-Film Thickness in Gear Teeth (1960)

The voltage drop across thin oil films when a constant current of 1 amp is passed, i.e., the discharge voltage, is used to measure the oil-film thickness between loaded gear teeth while running. It is found that the thickness at the pitch line is between 1 and 4 × 10−4 in., which varies slightly with the viscosity and rather more strongly with load. The thickness at the tips and roots is very dependent on the tip relief. The conditions here may explain the difference between disk and gear tests. These experimental values are compared with theoretical work and are shown to be of the same order of magnitude.

Why clone horses and mules? (2004)

The ability to produce offspring from animals otherwise incapable of reproduction has important implications in the equine. Routinely, male equines are electively castrated to produce animals (geldings) that are more easily managed and handled. These animals are then much more conveniently and safety used in various competitions such as cutting, reining, polo, roping, and racing. The ability to recover the genetics of animals that either prematurely die or die prior to sufficient impact of valuable genomics is an important consideration in the horse.
