SentiWordNet: A High-Coverage Lexical Resource for Opinion Mining (2006)

Introduction An odontogenic keratocyst (OKC) is a benign intraosseous lesion with potential to demonstrate aggressive and invasive behavior. The aim of this retrospective study was to analyze the imaging features of the OKC using cone-beam computed tomography (CBCT) and to evaluate the association between the internal structure of the lesion and the effect of the lesion on surrounding structures. Methods Overall, 32 CBCT scans of histopathologically diagnosed cases of OKC were analyzed retrospectively. The following variables were analyzed: anatomic location of the lesions (mandible body (right/left), ramus (right/left), mandible body+ramus (right/left), maxilla (right/left), and both jaws), the internal structure of the lesion (unilocular/multilocular), and the effect of the lesion on the surrounding anatomical structures (involvement of the inferior alveolar nerve canal (IANC), displacement of the IANC, cortical expansion, displacement of the tooth, resorption of the root, associated impacted tooth, associated missing tooth). We also looked for the association between the internal structure and the effect of the lesion on anatomic structures. Results Out of 32 cases, 29 (90.6%) cases involved the mandible alone. Statistically significant association (p-value 0.005) was present between the internal structure and mean age of presentation as well as between the internal structure and impacted tooth (p-value 0.027). The association between the internal structure and other variables was statistically not significant. Conclusions The radiographic features of OKCs can be variable, and these lesions have a considerable effect on the tooth, IANC, and cortical bone. Significant association was found between the internal structure, age, and impacted tooth. Since OKCs have a high recurrence rate, CBCT is advised for evaluating the extent and location of any cortical perforations.
A rapid method, using octadecasilyl-silica, for the extraction of certain peptides from tissues (1978)

Peptides can be recovered from tissues by homogenization in a carefully selected extraction medium followed by adsorption from the supernatant on a small bed of octadecasilyl-silica. Recoveries of corticotropins and somatostatin added to a variety of tissues were quantitative, and the peptides undamaged as determined by high-pressure liquid chromatography.
Optical properties of edible oils within spectral range from 300 to 2500  nm determined by double optical pathlength transmission method (2015)

The optical properties of nine different samples of edible oils were experimentally determined by double optical pathlength transmission method in the spectral range from 300 to 2500 nm between 20°C and 80°C. The index of refraction exhibits little difference from the different types of edible oils. The index of absorption of all brands of studied edible oils decreased with the increasing temperature in the spectral range from 500 to 1100 nm. The variation of index of absorption was found to be insensitive to the increasing of temperature in the spectral range from 300 to 500 nm and from 1100 to 2500 nm. The absorption peaks locating at 900, 1210, 1400, 1750, 2150, and 2300 nm of the measured edible oils were corresponding to the result of overtones and combinations of C─H stretching vibration of various chemical groups. A difference of index of absorption was observed among the peanut oil, soybean oil, and sunflower oil in the spectral range from 300 to 500 nm.
<i>Antheacheres duebeni</i>M. Sars, a copepod parasitic in the sea anemone,<i>Bolocera tuediae</i>(Johnston) (1970)

Abstract Aspects of the biology and data on the frequency of the gall-forming copepod, Antheacheres duebeni M. Sars, are presented, based on regular samples of its host, the sea anemone, Bolocera tuediae (Johnston), in Korsfjorden, western Norway. About half of the Bolocera found were infected by the copepod. Sea anemones of all sizes were parasitized, but big specimens more frequently than small ones. Ovigerous females of Antheacheres have been observed throughout the year, and in hosts of all sizes. Nauplii hatched in the laboratory have lived for about a month, but moulted only once. Up to 300 Antheacheres have been counted in a single Bolocera specimen, but even at this density the parasite does not seem to interfere with the reproduction of its host.
The Micromolar Zinc-Binding Domain on the NMDA Receptor Subunit NR2B (2005)

Eukaryotic ionotropic glutamate receptor subunits possess a large N-terminal domain (NTD) distinct from the neighboring agonist-binding domain. In NMDA receptors, the NTDs of NR2A and NR2B form modulatory domains binding allosteric inhibitors. Despite a high sequence homology, these two domains have been shown to bind two ligands of strikingly different chemical nature. Whereas the NTD of NR2A binds zinc with high (nanomolar) affinity, the NTD of NR2B binds the synthetic neuroprotectant ifenprodil and its derivatives. Using both NTD-mutated/deleted receptors and isolated NTDs, we now show that the NTD of NR2B, in contrast to NR2C and NR2D, also binds zinc, but with a lower affinity. Furthermore, we present evidence that zinc and ifenprodil compete for an overlapping binding site. This modulatory binding site accounts for the submicromolar zinc inhibition of NR1/NR2B receptors. Given that zinc is accumulated and released at many glutamatergic synapses in the CNS, these findings suggest that zinc is the endogenous ligand of the NTD of both NR2A and NR2B, the two major NR2 subunits. Thus, NMDA receptors contain zinc sensors capable of detecting extracellular zinc over a wide concentration range depending on their NR2 subunit composition. The coexistence of subunit-specific zinc-binding sites of high (nanomolar) and low (micromolar) affinity on NMDA receptors raises the possibility that zinc exerts both a tonic and a phasic control of membrane excitability.
Highly Pathogenic Avian Influenza A/H5N1 – update and overview of 2006 (2006)

Copying files from the clipboard to a command prompt (2000)

Diffuse cerebral ischemia was created in pentobarbital-anesthetized cats by basilar and bilateral carotid artery occlusions and hypotension. Local cerebral blood flow (ICBF) was assessed autoradiographically with 14C-antipyrine, and local cerebral glucose utilization with 14C-2-deoxyglucose. In animals without glucose pretreatment, 15 min of ischemia led to a homogeneous reduction of post-ischemic cerebral perfusion to 31% of control; ischemia of 30 min produced post-ischemic perfusion heterogeneities in the cerebral cortex and deep gray structures. In animals pretreated with dextrose, 1.5 gm/kg intravenously, heterogeneous cerebral perfusion was observed following only 15 min of ischemia, and a severe global impairment of cerebral reperfusion occurred after the 30 min insult. Deoxyglucose autoradiograms in the latter animals were remarkable for a complete suppression of tracer uptake in the cerebral cortex and a paradoxically increased tracer concentration in the cerebral white matter. Mean plasma glucose in the treated animals exceeded 1000 mg/100 ml. Large glucose loads prior to ischemia dramatically impair post-ischemic cerebral perfusion.
Thermogravimetric Study of the High‐Temperature Oxidation of Cu and Fe With and Without Vitreous Coatings (1971)

The study of the oxidation of Cu and Fe by continuous recording of weight gain is described. Equations are given for the rates of oxidation at several temperatures of the metals, both uncoated and enamel‐coated. Uncoated Cu was less strongly oxidized than uncoated Fe, but coated Cu was more strongly oxidized than coated Fe. The presence of CoO in the coating caused no significant difference in the action of the enamels on the metals.
Δ6 desaturase in brain and liver during development and aging (1990)

Abstract Δ6 Desaturase was measured in the mouse brain and liver using linoleic acid as substrate. During pre‐ and postnatal development, Δ6 desaturase in brain decreased dramatically (12‐fold) up to postnatal day 21 and remained nearly constant thereafter. In liver, the activity increased approximately 9‐fold between day 3 before birth and day 7 after birth. Then it decreased slightly up to weaning and was approximately constant up to 4 mo. From then on, Δ6 desaturase decreased with age (40% between 4 and 17 mo).
On Transitive Consistency for Linear Invertible Transformations between Euclidean Coordinate Systems (2015)

Transitive consistency is an intrinsic property for collections of linear invertible transformations between Euclidean coordinate frames. In practice, when the transformations are estimated from data, this property is lacking. This work addresses the problem of synchronizing transformations that are not transitively consistent. Once the transformations have been synchronized, they satisfy the transitive consistency condition - a transformation from frame $A$ to frame $C$ is equal to the composite transformation of first transforming A to B and then transforming B to C. The coordinate frames correspond to nodes in a graph and the transformations correspond to edges in the same graph. Two direct or centralized synchronization methods are presented for different graph topologies; the first one for quasi-strongly connected graphs, and the second one for connected graphs. As an extension of the second method, an iterative Gauss-Newton method is presented, which is later adapted to the case of affine and Euclidean transformations. Two distributed synchronization methods are also presented for orthogonal matrices, which can be seen as distributed versions of the two direct or centralized methods; they are similar in nature to standard consensus protocols used for distributed averaging. When the transformations are orthogonal matrices, a bound on the optimality gap can be computed. Simulations show that the gap is almost right, even for noise large in magnitude. This work also contributes on a theoretical level by providing linear algebraic relationships for transitively consistent transformations. One of the benefits of the proposed methods is their simplicity - basic linear algebraic methods are used, e.g., the Singular Value Decomposition (SVD). For a wide range of parameter settings, the methods are numerically validated.
Mineralocorticoid and Glucocorticoid Receptor‐Mediated Effects on Serotonergic Transmission in Health and Disease (2004)

Corticosterone is released in large amounts from the rat and mouse adrenal gland after stress. The hormone enters the brain and binds to intracellular receptors. Previously, we found that rises in the corticosterone level, as after acute stressors, enhance the response of hippocampal CA1 neurons to serotonin (5-HT), which hyperpolarizes the membrane via the 5-HT1A receptor. Recently, we examined how 5-HT responses are affected by more persistent changes in circulating hormone levels. In chronically stressed rats, we observed that 5-HT responses with both basal and high corticosterone levels are attenuated compared to those in the controls; 5-HT1A receptor expression was not altered. Similarly, in long-attack latency mice, which are characterized by a hyperresponsive hypothalamus-pituitary-adrenal axis, 5-HT responses were diminished, accompanied by reduced receptor expression. Finally, rats that for 24 h were deprived of their mother at postnatal day 3 exhibited attenuated 5-HT responses when tested at 3 months of age, in the absence of changes in the 5-HT1A receptor expression. We conclude that prolonged exposure to elevated corticosterone levels attenuates 5-HT responses in the hippocampus through an unresolved mechanism. This may be relevant to the observation that hypercortisolism in humans is a risk factor for the precipitation of major depression in genetically predisposed individuals.
A parallel indexed algorithm for information retrieval (1989)

In this paper we present a parallel document ranking algorithm suitable for use on databases of 1-1000 GB, resident on primary or secondary storage. The algorithm is based on inverted indexes, and has two advantages over a previously published parallel algorithm for retrieval based on signature files. First, it permits the employment of ranking strategies which cannot be easily implemented using signature files, specifically methods which depend on document-term weighting. Second, it permits the interactive searching of databases resident on secondary storage. The algorithm is evaluated via a mixture of analytic and simulation techniques, with a particular focus on how cost-effectiveness and efficiency change as the size of the database, number of processors, and cost of memory are altered. In particular, we find that if the ratio of the number of processors and/or disks to the size of the database is held constant, then the cost-effectiveness of the resulting system remains constant. Furthermore, for a given size of database, there is a number of processors which optimizes cost-effectiveness. Estimated response times are also presented. Using these methods, it appears that cost-effective interactive access to databases in the 100-1000 GB range can be achieved using current technology.
Sheddable Ternary Nanoparticles for Tumor Acidity-Targeted siRNA Delivery (2011)

Drug delivery systems for cancer therapy usually need to be sterically stabilized by a poly(ethylene glycol) (PEG) layer during blood circulation to minimize nonspecific interactions with serum components. However, PEGylation significantly reduces cellular uptake of the delivery systems after they accumulate at the tumor site, which markedly impairs the in vivo antitumor efficiency. Here, we develop a ternary small interfering RNA (siRNA) delivery system with tumor acidity-activated sheddable PEG layer to overcome the challenge. The sheddable nanoparticle is fabricated by introducing a tumor acidity-responsive PEGylated anionic polymer to the surface of positively charged polycation/siRNA complexes via electrostatic interaction. We show clear evidence that introducing the PEGylated anionic polymer to the surface of a nanoparticle markedly reduces its nonspecific interactions with protein. We further demonstrate that the nanoparticle is capable of deshielding the PEG layer at the slightly acidic tumor extracellular microenvironment to facilitate the delivery of siRNA to the tumor cells after accumulation at the tumor site. Accordingly, this promotes the RNA-interfering efficiencies and enhances the inhibition of tumor growth. Such delivery system with the ability to deshield the PEG layer at the target tissues has remarkable potential in cancer therapy.
New PNHN Pincer-Type Ligands and Their Complexes for Transfer Hydrogenation (2009)

The ligand tBu2PC2H4NHCH2Py (PNHN) was synthesized starting from 2-pyridinecarboxaldehyde and 2-chloroethanamine. Initial attempts for coordination of the PNHN ligand to a metal center was performed using [IrCl(COE)2]2, IrCl3·3H2O, [RuCl2(p-cymene)]2 and RuCl2(PPh3)3. The reaction between the PNHN ligand and [IrCl(COE)2]2 under H2 resulted in the chloride IrCl(H)2(PNHN). Synthesis of the active hydride species is currently under investigation. A reaction of the PNHN ligand with RuCl2(PPh3)3 under nitrogen afforded the dichloride RuCl2(PPh3)(PNHN). Treatment of the dichloride with KOBut in 2-pentanol led to the formation of the dihydride RuH2(PPh3)(PNHN). Formation of the 16-electron amido complex RuH(PPh3)3(PNN) was achieved through the evolution of H2. The dihydride demonstrated good potential catalytic activity for transfer hydrogenation of acetophenone and cyclohexanone. Current work involves the synthesis of a chiral analogue of the PNHN ligand.
Dual-JT: Toward the high availability of JobTracker in Hadoop (2012)

MapReduce is a state-of-the-art computation paradigm that is becoming widely used for processing large-scale datasets. Hadoop is an open-source implementation of MapReduce and follows a masterCslave architecture. This architecture makes Hadoop suffer from a single point of failure in the JobTracker. In this paper, we design a solution to resolve the single point of failure of the Job Tracker and then enhance its availability. In this solution, a standby Job Tracker is introduced to act as a hot backup node of the active Job Tracker. The standby Job Tracker synchronizes the job execution process with the active Job Tracker by collecting and parsing the job log. If the active Job Tracker fails, the standby Job Tracker can take over quickly. This solution is implemented in Hadoop 0.20.x. Extensive experiments illustrate that this solution effectively enhances the availability of Job Tracker. A big production cluster in a large e-Commerce company has adopted this solution, which avoids interrupting job submission and execution when the Job Tracker fails or restarts.
Stochastic Modeling of Dendritic Grain Structures (2001)

A three-dimensional cellular automaton-finite element model has been developed over the past five years for the prediction of macrostructures formed in casting. The present article briefly summarizes the growth algorithm of the model. Applications are then given for the prediction of the grain structure formed in a directionally solidified turbine blade produced by investment casting, a continuously cast cylinder and a near-net shape steel sheet obtained by twin-roll casting.

SITE ACCOMMODATION ON MAJOR ROAD CONTRACTS (1984)

The paper describes a contractor's basic requirements for site accommodation and the considerations to be made in satisfying these. Early establishment on site is essential and the acquisition of land and services must reflect this urgency. Careful planning is necessary in chosing the final arrangement of all the site accommodation to ensure efficiency in usage of space, operation and safety. Security can pose separate problems and this aspect must also be included in the planning process. Finally some general comments are made concerning the clearance of the site, and also in respect of a temporary caravan site established for contractor's elmployees. (Author/TRRL)

Informations- und kommunikationstechnische Entwicklungen durchdringen immer stärker unser Privat- und Geschäftsleben und verändern Markt- und Unternehmensstrukturen nachhaltig. Kaum eine Institution ist nicht von diesen Entwicklungen betroffen. Dies trifft insbesondere auf Banken zu, die in doppelter Hinsicht tangiert sind: zum einen verändern informations- und kommunikationstechnische Entwicklungen Bankgeschäft und Bankorganisation direkt, zum anderen verändern sie die Organisationsstrukturen ihrer Kunden, was wiederum Auswirkungen auf Bankgeschäft und Bankorganisation hat. Diese Auswirkungen gilt es im folgenden Beitrag aufzuzeigen. Nach einem kurzen Überblick über wichtige informations- und kommunikationstechnische Entwicklungen werden Auswirkungen auf typische Bankgeschäfte und ihre organisatorische Gestaltung skizziert.
Isolation and identification of carotenoid pigments, lipids and flavor active components from raw commercial shrimp waste (1991)

Abstract Crustacean waste generated from the fishing industry represents approximately 70% of the total landings. This abundant waste may pose an environmental hazard due to the ease of deterioration of the fish tissue in the landfill sites; disposing of the waste, therefore, can be achieved at considerable cost to the industry. Alternatively, the waste can be utilized by extracting useful components such as pigments, lipids and flavor active components and Incorporating them into desirable seafood products. Carotenoid pigments (13‐carotene, canthaxanthin, astacene and astaxanthin monopalmitate) were extracted and separated by thick layer chromatography using silica gel and their structures identified tentatively by TLC and subsequently the identifications were confirmed by Fourier transformed infrared (FT‐IR) spectroscopy; Iipids were separated and categorized into glycerides, sterols and phospholipids by thin layer chromatography; flavor active components were extracted by different organic solvents and separated into acidic, weakly acidic, basic and neutral fractions and their sensory properties determined.
Implementation issues when installing control and condition monitoring at water treatment works (1998)

Monitoring (and control) systems at many of Northumbrian Water's treatment sites are based on a highly centralised configuration. A study was carried out on a programme of control system development and enhancement that would realise: (i) a high degree of reliability in the system operation, (ii) consistently good quality water satisfying stringent EU regulations, (iii) reduced operational costs, and (iv) improved standards of safety and environmental protection. It was anticipated that such a study would highlight the benefits of a distributed control scheme. The first part of the study was to collect information on the topology and operational condition of the various loops which together provide the basic plant monitoring and control support for the diverse water treatment plant which constitute the supply base. The paper documents some of the findings of these investigations but first a brief explanation of the various unit operations which together represent a typical surface (river or reservoir) water treatment plant employing a basic three stage (clarification, filtration and disinfection) treatment process.
Precise Dynamic Impact Analysis with Dependency Analysis for Object-oriented Programs (2007)

Dynamic impact analysis based on program executions has shown promise in aiding tasks in the life cycle of large-scale systems. Dynamic impact analysis techniques have shown to produce more precise results than static impact analysis [1]. However, current dynamic impact analysis techniques lack important features such as analysis of dependency among program entities and consideration of object-oriented programs ' features. Thus they may produce imprecise results. In this paper, we present a precise dynamic impact analysis approach for object-oriented programs. This approach considers the characteristics of object- oriented programs and performs dependency analysis which may potentially reduce the impact sets by eliminating elements that do not have dependency on the changed elements. Even though our discussion in this paper is based on Java <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">TM</sup> programming language, this approach can be carried out in a language independent manner for broader applications.
