Management and control for giant gigabit networks (1993)

The authors describe the new challenges presented for the management of broadband networks and outline the framework of the COMET research group at Columbia University for finding solutions to these challenges. They review a prototype that implements some of the requirements for managing the broadband networks of the future. In the COMET framework, management operations are defined in terms of primitives with a much higher semantic level than that typified by get and set in the Open Systems Interconnection (OSI) management model, and the user interface to the managed system is based on virtual worlds that allow the manager to directly visualize and interact with the network. The impact that this new environment may have on existing management architectures is discussed.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Effects of vitamins and trace-elements supplementation on milk production in dairy cows: A review (2011)

During the past decade, significant advances were made in understanding the effects of vitamins and trace-elements supplement on milk production of dairy cows. This work discussed the effects of vitamins and trace-elements supplementation on milk production of dairy cows. Studies have indicated that vitamin A (VA) and β-carotene (BC) supplementation have some effects on udder health and milk yield in dairy cows whose intake is below 110 IU/kg BW/day. If low quality forage is fed, supplementation of VA should be considered. Supplementation of B-vitamin has important effects on milk production and could increase milk yield and milk component production. The effect of vitamin E (VE) and selenium (Se) supplementation on the milk yield and milk components are not unified due to the optimum dose, route and timing of VE administration in lactational dairy cows. Zinc (Zn) supplementation increases lactation performance and reduces milk somatic cell count (SCC) in most studies. Limited research has indicated that copper (Cu) supplementation could reduce milk SCC. Before deciding to supplement vitamins and trace-minerals indicated earlier for the improvement of milk production of lactational cows, farmers should have their animals fed with tested and evaluated rations to be sure of the levels of supplementation which may be warranted.   Key words: Vitamin, trace-element, dairy cow, milk production.
Targeted Mutations in a Trametes villosa Laccase (1999)

Trametes villosa laccase was mutated on a tetrapeptide segment near the type 1 site. The mutations F463M and F463L were at the position corresponding to the type 1 copper axial methionine (M517) ligand in Zucchini ascorbate oxidase. The mutations E460S and A461E were near the T1 copper site. The mutated Trametes laccases were expressed in an Aspergillus oryzae host and characterized. The E460S mutation failed to produce a transformant with meaningful expression. The F463L and A461E mutations did not significantly alter the molecular and enzymological properties of the laccase. In contrast, the F463M mutation resulted in a type 1 copper site with an EPR signal intermediate between that of the wild type laccase and plastocyanin, an altered UV-visible spectrum, and a decreased redox potential (by 0.1 V). In oxidizing phenolic substrate, the mutation led to a more basic optimal pH as well as an increase in kcat and Km. These effects are attributed to a significant perturbation of the T1 copper center caused by the coordination of the axial methionine (M463) ligand.
Broadband super-collimation in a hybrid photonic crystal structure (2009)

We propose a two dimensional (2D) photonic crystal (PhC) structure that supports super-collimation over a large frequency range (over 4 times that of a traditional square lattice of holes). We theoretically and numerically investigate the collimation mechanism in our 2D structure, in comparison to that of two other frequently used related PhC structures. We also point out the potential importance of our proposed structure in the design of super-collimation-based devices for both monochromatic and polychromatic light.
Novel Peptide NIRF Optical Surgical Navigation Agents for HNSCC (2019)

Head and neck squamous cell carcinoma (HNSCC) survival rates have not improved in a decade, with a 63% 5-year recurrence rate after surgery, making HNSCC a compelling indication for optical surgical navigation (OSN). A promising peptide, HN1, targeted and internalized in human HNSCC cells in multiple laboratories, but was slow (24 h) to accumulate. We modified HN1 and explored structural variables to improve the uptake kinetics and create IRdye800 adducts useful for OSN. Eleven new molecules were synthesized and characterized chemically, in human HNSCC cells (Cal 27), and in HNSCC xenograft mice. Cal 27 flank xenografts in Balb/c nude mice were imaged for 3-48 h after 40 nmol intravenous doses of IR800-labeled molecules. Cell uptake kinetics in the 1-2 h window incubated at 1-10 μM were independent of the dye label (FITC, Cy5, or IR800), but increased markedly with additional N-terminal lipophilic substitution, and after resequencing the peptide to separate polar amino acids and move the lysine-dye more centrally. Microscopy confirmed the strong Cal 27 cell binding and demonstrated primarily cytosolic and membrane localization of the fastest peptide, 4Iphf-HN17. 4Iph-HN17-IR800 showed 26-fold greater rate of uptake in cells than HN1-IR800, and far stronger OSN imaging intensity and tumor to background contrast in mice, suggesting that the new peptide is a promising candidate for OSN of HNSCC.
Does the difference between physically active and couch potato lie in the dopamine system? (2010)

Obesity and other inactivity related diseases are increasing at an alarming rate especially in Western societies. Because of this, it is important to understand the regulating mechanisms involved in physical activity behavior. Much research has been done in regard to the psychological determinants of physical activity behavior; however, little is known about the underlying genetic and biological factors that may contribute to regulation of this complex trait. It is true that a significant portion of any trait is regulated by genetic and biological factors. In the case of voluntary physical activity behavior, these regulating mechanisms appear to be concentrated in the central nervous system. In particular, the dopamine system has been shown to regulate motor movement, as well as motivation and reward behavior. The pattern of regulation of voluntary physical activity by the dopamine system is yet to be fully elucidated. This review will summarize what is known about the dopamine system and regulation of physical activity, and will present a hypothesis of how this signaling pathway is mechanistically involved in regulating voluntary physical activity behavior. Future research in this area will aid in developing personalized strategies to prevent inactivity related diseases.
Mechanisms of Hypertension (2004)

Hypertension is a common disorder that affects a large heterogeneous patient population. Subgroups can be identified on the basis of their responses to hormonal and biologic stimuli. These subgroups include low-renin hypertensives and nonmodulators. Aldosterone, the principal human mineralocorticoid, is increasingly recognized as playing a significant role in cardiovascular morbidity, and its role in hypertension has recently been reevaluated with studies that suggest that increased aldosterone biosynthesis (as defined by an elevated aldosterone to renin ratio) is a key phenotype in up to 15% of individuals with hypertension. It was reported previously that a polymorphism of the gene (C to T conversion at position -344) encoding aldosterone synthase is associated with hypertension, particularly in individuals with a high ratio. However, the most consistent association with this variant is a relative impairment of adrenal 11beta-hydroxylation. This review explores the evidence for this and provides a hypothesis linking impaired 11beta-hydroxylation and hypertension with a raised aldosterone to renin ratio. It is also speculated that there is substantial overlap between this group of patients and previously identified low-renin hypertensives and nonmodulators. Thus, these groups may form a neurohormonal spectrum reflecting different stages of hypertension or indeed form sequential steps in the natural history of hypertension in genetically susceptible individuals.

An Effective Immunization of Experimental Monkeys Against a Human Malaria Parasite, <i>Plasmodium falciparum</i> (1977)

This is the first report of successful immunization of experimental monkeys against a human malaria parasite, Plasmodium falciparum. Of the five owl monkeys (Aotus trivirgatus) used in this pilot study, two served as controls and the other three were immunized with P. falciparum antigen consisting primarily of mature segmenters containing fully developed merozoites. Two injections of antigen emulsified with Freund's complete adjuvant were administered intramuscularly 3 weeks apart. Three weeks after the second vaccination, all monkeys were challenged with the homologous strain of P. falciparum. The control monkeys died with high levels of parasitemia within 2 weeks of challenge. The three immunized monkeys survived and showed strong protection against P. falciparum. These results are encouraging for the possible future development of an effective vaccine against human malaria.
Evaluation of a New Slide-based Laser Scanning Cytometer for DNA Analysis of Tumors:<i>Comparison with Flow Cytometry and Image Analysis</i> (1994)

DNA measurements generated by a new automated slide-based cytometer, the laser scanning cytometer (LSC), were compared with those produced by commercial flow cytometry (FCM) and image analysis (IA) devices. Laser scanning-cytometric analysis was performed by scanning alcohol-fixed, propidium iodide-stained tumor imprints with a 5-microns spot laser beam. Fifty-three malignant tumors (51 breast carcinomas and 2 lung carcinomas) were studied. Ploidy concordance rates for FCM versus LSC, IA versus LSC, and FCM versus IA were 96%, 91%, and 91%, respectively. Statistically significant agreement between methods was determined by linear regression analysis of DNA indices. Synthesis-phase fractions generated by FCM and LSC also were comparable, as demonstrated by linear regression (r = .83). Mean coefficients of variation for the LSC compared favorably with those for FCM and IA. The few discrepancies in ploidy status between methods could be explained by sampling error, the presence of possible near-diploid aneuploid populations that could not be effectively resolved by one or another modality, and the visual selection bias with IA when small aneuploid cell populations were present. The LSC shares many useful features with FCM, including automation, accuracy of quantitation, rapidity, and generation of reliable information regarding cell proliferation (synthesis-phase fraction). In addition, it has some of the advantages of IA, such as minimal tissue requirement, no need for special preparation, and the potential for visual selection of the cells measured. The LSC holds great promise for use in the clinical laboratory because of these combined characteristics.
Ion‐Channel Modulators: More Diversity Than Previously Thought (2011)

Ion-channel function can be modified in various ways. For example, numerous studies have shown that currents through voltage-gated ion channels are affected by pore block or modification of voltage dependence of activation/inactivation. Recent experiments performed on various ion channels show that allosteric modulation is an important mechanism for affecting channel function. For instance, in K(Ca)2 (formerly SK) channels, the prototypic "blocker" apamin prevents conduction by an allosteric mechanism, while TRPV1 channels are prevented from closing by a tarantula toxin, DkTx, through an interaction with residues located away from the selectivity filter. The recent evidence, therefore, suggests that in several ion channels, the region around the outer mouth of the pore is rich in binding sites and could be exploited therapeutically. These discoveries also suggest that the pharmacological vocabulary should be adapted to define these various actions.
Effects of Dietary Tea Catechins on .ALPHA.-Tocopherol Levels, Lipid Peroxidation, and Erythrocyte Deformability in Rats Fed on High Palm Oil and Perilla Oil Diets. (1993)

The effects of dietary tea catechins on the levels of alpha-tocopherol and lipid peroxidation in both plasma and erythrocytes, as well as their effects on erythrocyte deformability, were examined in rats fed on high palm and perilla oil diets. The decrease in alpha-tocopherol concentration and the increase in lipid peroxidation level were much more pronounced in the perilla oil group than in the palm oil group. The addition of tea catechins to these diets significantly prevented the alpha-tocopherol concentration from decreasing. These results suggest that tea catechins may counteract a decrease in alpha-tocopherol by acting as an antioxidant in vivo. Furthermore, the lipid peroxidation in the plasma of rats fed perilla oil was slightly but significantly reduced by the supplemented tea catechins. However, no measurable differences were observed in the deformability of the erythrocytes in any of the groups. It is therefore likely that the erythrocytes are not severely enough affected by the lipid peroxidation to influence their deformability.
Derby's Third Premiership: 1866–1868 (2008)

This chapter discusses the third premiership of Lord Derby from 1866 to 1868. Derby became prime minister of Great Britain for the third time in July 1866. He was again facing major political problems. The Adullamites demanded as a condition for the Liberal Party's merger with the Conservatives the resignation of Derby. But Derby refused and he was determined never to hold a subordinate place and not to be a minister on sufferance again.
A system for semiconductor process specification (1993)

The SPEC system for capturing and managing semiconductor fabrication process information is discussed. The SPEC data model decomposes process specifications into equipment, step, process, and flow hierarchies. Mechanisms within an interactive graphical user interface provide a high degree of user control over the expression and organization of objects within each layered hierarchy and control the information in terms of collection, propagation to other layers, and the appearance of the data within specification folders using a what you see is what you get (WYSIWYG) folder builder. Implementation on a concurrent object-oriented database permits simultaneous use of the SPEC system by many users.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
A Single Generative Model for Joint Morphological Segmentation and Syntactic Parsing (2008)

Morphological processes in Semitic languages deliver space-delimited words which introduce multiple, distinct, syntactic units into the structure of the input sentence. These words are in turn highly ambiguous, breaking the assumption underlying most parsers that the yield of a tree for a given sentence is known in advance. Here we propose a single joint model for performing both morphological segmentation and syntactic disambiguation which bypasses the associated circularity. Using a treebank grammar, a data-driven lexicon, and a linguistically motivated unknown-tokens handling technique our model outperforms previous pipelined, integrated or factorized systems for Hebrew morphological and syntactic processing, yielding an error reduction of 12% over the best published results so far. 1
1920x1080 pixel color camera with progressive scan at 50 to 60 frames per second (1998)

For over a decade, the broadcast industry, the film industry and the computer industry have had a long-range objective to originate high definition images with progressive scan. This produces images with better vertical resolution and much fewer artifacts than interlaced scan. Computers almost universally use progressive scan. The broadcast industry has resisted switching from interlace to progressive because no cameras were available in that format with the 1920 X 1080 resolution that had obtained international acceptance for high definition program production. The camera described in this paper produces an output in that format derived from two 1920 X 1080 CCD sensors produced by Eastman Kodak.

Correlation between Gas Sensitivity and Crystallite Size in Porous SnO2-Based Sensors (1990)

Abstract The gas sensing properties of SnO2-based sensors in which the size of SnO2 crystallites was controlled by various dopants were investigated. It was found that the gas sensitivity to H2, CO or i-C4H10 increased as the SnO2 crystallite size decreased in the range below 10 nm. Quite high gas sensitivity was achieved at a crystallite size of ca. 5 nm.
Association of RAB5 overexpression in pancreatic cancer with cancer progression and poor prognosis via E-cadherin suppression (2017)

Pancreatic cancer is a common type of cancer with poor prognosis worldwide. Postoperative survival depends on the existence of metastasis. Elucidation of the mechanism underlying cancer progression is important to improve prognosis. The RAS-associated protein RAB5 activates intracellular membrane trafficking, and RAB5 expression is correlated to progression and epithelial mesenchymal transition in various cancers.The expression of RAB5 and E-cadherin in 111 pancreatic cancer samples was investigated by immunohistochemical staining, and the relationship among RAB5 expression, clinicopathological factors, and E-cadherin expression was assessed. Furthermore, RAB5 suppression analysis by siRNA was performed to determine the roles of RAB5 in morphological change, proliferation potency, cell migration ability, and invasiveness of the pancreatic cancer cell line.High RAB5 expression correlated with the presence of lymphatic invasion and venous invasion and low E-cadherin expression. Patients with high RAB5 expression had a poorer prognosis than those with low RAB5 expression. RAB5 suppression in pancreatic cancer cells enhanced E-cadherin expression; changed cell morphology from spindle to round; and inhibited proliferation, invasion, and cell migration.RAB5 contributes to poor prognosis and progression in pancreatic cancer patients. It may be a promising candidate for individualized therapy in refractory pancreatic cancer.
Top 10 plant pathogenic bacteria in molecular plant pathology (2012)

Many plant bacteriologists, if not all, feel that their particular microbe should appear in any list of the most important bacterial plant pathogens. However, to our knowledge, no such list exists. The aim of this review was to survey all bacterial pathologists with an association with the journal Molecular Plant Pathology and ask them to nominate the bacterial pathogens they would place in a 'Top 10' based on scientific/economic importance. The survey generated 458 votes from the international community, and allowed the construction of a Top 10 bacterial plant pathogen list. The list includes, in rank order: (1) Pseudomonas syringae pathovars; (2) Ralstonia solanacearum; (3) Agrobacterium tumefaciens; (4) Xanthomonas oryzae pv. oryzae; (5) Xanthomonas campestris pathovars; (6) Xanthomonas axonopodis pathovars; (7) Erwinia amylovora; (8) Xylella fastidiosa; (9) Dickeya (dadantii and solani); (10) Pectobacterium carotovorum (and Pectobacterium atrosepticum). Bacteria garnering honourable mentions for just missing out on the Top 10 include Clavibacter michiganensis (michiganensis and sepedonicus), Pseudomonas savastanoi and Candidatus Liberibacter asiaticus. This review article presents a short section on each bacterium in the Top 10 list and its importance, with the intention of initiating discussion and debate amongst the plant bacteriology community, as well as laying down a benchmark. It will be interesting to see, in future years, how perceptions change and which bacterial pathogens enter and leave the Top 10.
Word Sense Disambiguation Improves Statistical Machine Translation (2007)

Recent research presents conflicting evi-dence on whether word sense disambigua-tion (WSD) systems can help to improve the performance of statistical machine transla-tion (MT) systems. In this paper, we suc-cessfully integrate a state-of-the-art WSD system into a state-of-the-art hierarchical phrase-based MT system, Hiero. We show for the first time that integrating a WSD sys-tem improves the performance of a state-of-the-art statistical MT system on an actual translation task. Furthermore, the improve-ment is statistically significant. 1
