Construction Tele-robot System With Virtual Reality (2008)

In this paper, a tele-robotics system for a construction machine is investigated. The system consists of a servo-controlled construction robot, two joysticks for controlling the robot, and a 3-dimensional virtual environment. Computer graphics (CG) of the robot and task objects are presented to the operator in virtual scene as a tool for assisting teleoperation. The operator performs remote operation of the construction robot by manipulating the graphic robot directly in virtual environment using the joysticks. The position and shape of the task objects in virtual world are updated in real time on basis of image information obtained by a stereo camera fixed in remote field. To improve the efficiency as well as security of teleoperation, and overcome the shortcomings (such as time-consuming judgement and mistaken selection of screen to be observed) of conventional three-screens visual display, the methods of auto point of view (APV) and semi-transparent object (STO) are introduced in this paper. Finally, A comparative study of a one-screen visual display combining APV and STO with the conventional three-screens visual display is carried out based on the results of evaluation experiments (task efficiency, risk indexes, questionnaire). These experiments confirmed that one-screen visual display combining APV and STO is superior in operability, safety, and reduction of stress.
Prevention of thromboembolism following elective hip surgery. The value of regional anesthesia and graded compression stockings. (1989)

Ninety-eight patients scheduled for elective hip arthroplasty receiving either general or regional anesthesia and graded compression stockings as the only thromboprophylactic treatment were screened for postoperative deep-venous thrombosis with 99mTc-plasmin scintimetry. The diagnosis of deep-venous thrombosis was established by phlebography and the diagnosis of pulmonary embolism by pulmonary perfusion and ventilation scintigraphy. Of 65 patients surgically treated under general anesthesia, 20 (31%) developed deep-venous thrombosis and six developed pulmonary embolism. Of 33 patients surgically treated using regional anesthesia, three (9%) developed deep-venous thrombosis and one developed a pulmonary embolus. The number of patients developing deep-venous thrombosis was significantly lower in the group receiving regional anesthesia compared with the group receiving general anesthesia. The results indicate the beneficial effects on the incidence of postoperative thromboembolic complications following elective hip surgery from the use of regional anesthesia and graded compression stockings.
Parametric and predictive analysis of horizontal well configurations for coalbed methane reservoirs in Appalachian Basin (2004)

It has been a well-established fact that the Appalachian Basin represents a high potential region for the Coalbed Methane (CBM) production. The thin coal beds in the Appalachian basin are characterized by low porosity and permeability values. Due to highly complex reservoir characteristics, different drilling techniques have been developed in order to improve ultimate gas recovery in the shortest possible time. It has been claimed that horizontal drilling is the optimum completion technique used in this region to maximize methane recovery from coalbed reservoirs.;Horizontal wells are considered to be effective in the relatively thin, naturally fractured reservoirs that are characterized by permeability anisotropy. With today's advanced drilling technology, the direction of a horizontal wellbore can be controlled, maximizing the gas production. The objective of this study is to review the various horizontal well configurations used for the recovery of coal bed methane. This study discusses different coalbed properties, and horizontal well patterns, that should be applied in different cases. In addition, the gas recovery and the flow rate associated to the drainage area for each pattern are discussed.;Various reservoir models with diversity of reservoir properties and different horizontal well configurations with various spacing between laterals have been investigated for the best possible gas recovery, using detailed sensitivity analysis, parametric study and intelligent modeling approach.
Reduction of Respiratory Syncytial Virus (RSV) in Tracheal Aspirates in Intubated Infants by Use of Humanized Monoclonal Antibody to RSV F Protein (1998)

Thirty-five children <2 years of age mechanically ventilated for respiratory syncytial virus (RSV) infection were randomized to receive an intravenous infusion of 15 mg/kg MEDI-493 or placebo. RSV concentration was measured in tracheal secretions by plaque assay before and at 24-h intervals after treatment. The reduction in tracheal RSV concentration from day 0 to day 1 (-1.7+/-0.28 vs. -0. 6+/-0.21 log10 pfu/mL; P=.004) and from day 0 to day 2 (-2.5+/-0.26 vs. -1.0+/-0.41 log10 pfu/mL; P=.012) was significantly greater in the MEDI-493 group than in the placebo group. RSV concentration in nasal aspirates did not differ significantly between the groups. No significant differences were observed in the tracheal aspirate white blood cell count, or myeloperoxidase or eosinophilic cationic protein concentration, or in measures of disease severity between the groups. Thus, treatment with 15 mg/kg MEDI-493 intravenously was well-tolerated and significantly reduced RSV concentration in tracheal aspirates of children with respiratory failure due to RSV.

Ki-4(scFv)–ETA′, a new recombinant anti-CD30 immunotoxin with highly specific cytotoxic activity against disseminated Hodgkin tumors in SCID mice (2000)

The human lymphocyte activation marker CD30 is highly overexpressed on Hodgkin/Reed-Sternberg cells and represents an ideal target for selective immunotherapy. We used the murine anti-CD30 hybridoma Ki-4 to construct a new recombinant immunotoxin (rIT) for possible clinical use in patients with CD30(+) lymphoma. Hybridoma V genes were polymerase chain reaction-amplified, assembled, cloned, and expressed as a mini-library for display on filamentous phage. Functional Ki-4 scFv obtained by selection of binding phage on the CD30-expressing Hodgkin lymphoma cell line L540cy was inserted into the bacterial expression vector pBM1.1 and fused to a deletion mutant of Pseudomonas exotoxin A (ETA'). Periplasmically expressed Ki-4(scFv)-ETA' demonstrated specific activity against a variety of CD30(+) lymphoma cells as assessed by different in vitro assays. To evaluate in vivo antitumor activity, severe combined immunodeficient mice challenged with human lymphoma cell lines were treated with the immunotoxin. The blood distribution time t(1/2)alpha of Ki-4(scFv)-ETA' was 19 minutes, and its serum elimination time t(1/2)alpha was 193 minutes. A single intravenous injection of 40 microg rIT 1 day after tumor inoculation rendered 90% of the mice tumor free, extending the mean survival time to more than 200 days compared with 38.1 days in the phosphate-buffered saline control group (P <.001). This new rIT is a promising candidate for further clinical evaluation in patients with Hodgkin lymphoma or other CD30(+) malignancies. (Blood. 2000;95:3909-3914)
Coulomb and light-induced electronic renormalization in quantum wells for electromagnetically induced transparency and light amplification without inversion (1994)

With a coherent pump laser coupling two electron levels in quantum wells, Coulomb and light-induced electronic renormalization is investigated according to the density-functional theory. On the basis of the renormalization, the optical response function for intersubband absorption of a probe light beam is studied. Both the electromagnetically induced transparency and the probe light amplification without inversion are observed. The influences of the pump field strength, frequency detuning, electron density, and δ-doping position are determined.
Optical gain of CdZnSe/ZnSe quantum well lasers (1991)

Polarization-dependent optical gain of recently demonstrated CdZnSe/ZnSe quantum well lasers is calculated for the first time. Our analysis is based on the multiband effective mass theory (k⋅p theory) and the density matrix formalism with intraband relaxation taken into account. It is shown theoretically that the TE mode gain is significantly larger than the TM mode gain for a wide range of carrier density. Comparison of the room-temperature TE mode gain of CdZnSe/ZnSe quantum well with that of GaAs/AlGaAs quantum well gives disappointing results for the II-VI semiconductor lasers. It is expected that the optical gain of the ZnSe-based semiconductor lasers would be substantially smaller than the optical gain of the GaAs-based semiconductor lasers for a same quantum well width and carrier density.
Insecticidal properties of monoterpenoid derivatives to the house fly (diptera: Muscidae) and red flour beetle (coleoptera: Tenebrionidae) (1994)

Abstract Monoterpenoid derivatives were synthesized and their insecticidal activities were evaluated against red flour beetles, Tribolium castaneum (Herbst), in fumigant bioassays and against house flies Musca domestica (L.) in topical, fumigant, and ovicidal bioassays. Acetate derivatives and haloacetate derivatives were compared with each other, and with the parent monoterpenoid to determine structure‐activity relationships. Acetate derivatives were more active than the propionate derivatives of cyclic monoterpenoids in the topical, fumigant, and ovicidal bioassays. Pivalates were topically more insecticidal than acetates to adult house flies, while the acetates had the greater ovicidal activity. Acetates and pivalates were more effective than haloacetates in the topical, red flour beetle fumigation and ovicidal bioassays. Fluoroacetates of cyclic monoterpenoids were the most effective house fly fumigants, followed by acetates, and trichloroacetates. Several derivatives were produced that displayed enhanced activity relative to the parent alcohols or phenols.
Recognition of Equations Using a Two-Dimensional Stochastic Context-Free Grammar (1989)

We propose using two-dimensional stochastic context-free grammars for image recognition, in a manner analogous to using hidden Markov models for speech recognition. The value of the approach is demonstrated in a system that recognizes printed, noisy equations. The system uses a two-dimensional probabilistic version of the Cocke-Younger-Kasami parsing algorithm to find the most likely parse of the observed image, and then traverses the corresponding parse tree in accordance with translation formats associated with each production rule, to produce eqn I troff commands for the imaged equation. In addition, it uses two-dimensional versions of the Inside/Outside and Baum re-estimation algorithms for learning the parameters of the grammar from a training set of examples. Parsing the image of a simple noisy equation currently takes about one second of cpu time on an Alliant FX/80.
Paired transcranial magnetic stimulation protocols reveal a pattern of inhibition and facilitation in the human parietal cortex (2000)

Intracortical inhibition (ICI) and facilitation (ICF) of the human motor cortex can be induced by paired transcranial magnetic stimulation (TMS). Although demonstrated in experimental animals, the existence of intracortical inhibitory and excitatory circuits in parietal sensory cortex has not been documented in humans. The aim of this study was to investigate the effects of paired TMS of the parietal cortex on contralateral tactile perception. Fifteen healthy subjects were involved in a task of discrimination of electrical stimuli delivered at near-threshold intensity of sensory perception over the left thumb. Paired TMS was delivered with a focal coil on the right posterior parietal lobe after various delays from the presentation of finger stimuli. The effects of different interstimulus intervals (ISI: 1, 3, 5, 7, 10 and 15 1 1 Bms1B) between the conditioning and the test TMS stimulus on tactile perception were studied. The conditioning stimulus intensity was set at 70 % of motor threshold, while test TMS intensity was 130 % of motor threshold. Single pulse suprathreshold TMS interfered with the perception of finger stimuli, while subthreshold stimuli such as the 'conditioning' stimuli had no effect on sensory perception. Paired TMS differentially influenced the performance depending on the ISI. At an ISI of 1 1 1 Bms1B, paired TMS stimuli induced a significant worsening of the performance compared with single pulse TMS; at an ISI of 5 1 1 Bms1B, paired TMS stimuli induced a significant facilitation of the performance compared with single pulse TMS, restoring baseline performance levels. These results suggest that paired TMS can reveal a selective pattern of ICI and ICF in the human parietal cortex.
Monoclonal antibodies in the diagnosis, detection and therapy of cancer (1982)

Synopsis The production of monoclonal antibodies specifying tumour associated antigens is illustrated by studies with a spontaneously arising rat mammary carcinoma (Sp4). Fusion of spleen cells from tumour-immune rats with mouse myeloma (P3NS1) yielded hybridomas secreting antibody reacting with a tumour specific antigen. These approaches have subsequently been used to produce monoclonal antibodies reacting with human osteogenic sarcoma, although in this case the antigens detected are tumour associated rather than tumour-specific. The diagnostic applications of these monoclonal antibodies have been explored particularly to evaluate whether radiolabelled preparations can be used for ‘imaging’ tumours. This approach has been validated with the human osteogenic sarcoma xenograft in tests showing that tumours can be detected by y-camera scanning following injection of 131 I-labelled antibody when used in conjunction with blood pool labelling using 113M In and a computerised subtraction technique. Monoclonal antibodies also have considerable potential for targetting drugs. These approaches are illustrated by studies using anti-rat mammary carcinoma Sp4 monoclonal antibody linked to adriamycin for therapy of subcutaneous tumour. In addition to drug conjugates, monoclonal antibodies are being used for targeting immunomodulating agents. This is illustrated by another series of studies in which the anti-human osteogenic sarcoma monoclonal antibody has been conjugated to human lymphoblastoid cell interferon to produce a reagent for activating host natural killer cells.
Changes in behavior and emotion under chicken domestication (2017)

Marino’s target article provides an overview of chickens’ cognition, emotion, and personality, with the aim of changing how people view chickens. In this commentary, I will agree that chickens deserve better than their reputation, but contend with a statement about the lack of behavioral change under chicken domestication.
Infrequent normal B lymphocytes express features of B-chronic lymphocytic leukemia. (1982)

An infrequent (2-3%) B lymphocyte subpopulation was found in the normal human tonsil and lymph nodes that shows the phenotypic characteristics of B-chronic lymphocytic leukemia (B-CLL) (rosette formation with mouse erythrocytes, weak expression of membrane Ig, staining for HLA-DR, and OKT1 or Leu-1 detecting a T cell-associated p65 antigen). Preliminary evidence suggests that at least a subpopulation of these cells is found, in small proportions, within the germinal centers. These cells were not observed in the human bone marrow. B-CLL may involve this peripheral B lymphocyte subset.
Atherosclerosis: a chronic inflammatory disease mediated by mast cells (2015)

Inflammation is a process that plays an important role in the initiation and progression of atherosclerosis and immune disease, involving multiple cell types, including macrophages, T-lymphocytes, endothelial cells, smooth muscle cells and mast cells. The fundamental damage of atherosclerosis is the atheromatous or fibro-fatty plaque which is a lesion that causes several diseases. In atherosclerosis the innate immune response, which involves macrophages, is initiated by the arterial endothelial cells which respond to modified lipoproteins and lead to Th1 cell subset activation and generation of inflammatory cytokines and chemoattractant chemokines. Other immune cells, such as CD4+ T inflammatory cells, which play a critical role in the development and progression of atherosclerosis, and regulatory T cells [Treg], which have a protective effect on the development of atherosclerosis are involved. Considerable evidence indicates that mast cells and their products play a key role in inflammation and atherosclerosis. Activated mast cells can have detrimental effects, provoking matrix degradation, apoptosis, and enhancement as well as recruitment of inflammatory cells, which actively contributes to atherosclerosis and plaque formation. Here we discuss the relationship between atherosclerosis, inflammation and mast cells.
Evaluation of CA-125 and soluble CD-23 in patients with pelvic endometriosis: a case-control study (2012)

Models of Sequence Evolution for DNA Sequences Containing Gaps (2001)

Most evolutionary tree estimation methods for DNA sequences ignore or inefficiently use the phylogenetic information contained within shared patterns of gaps. This is largely due to the computational difficulties in implementing models for insertions and deletions. A simple way to incorporate this information is to treat a gap as a fifth character (with the four nucleotides being the other four) and to incorporate it within a Markov model of nucleotide substitution. This idea has been dismissed in the past, since it treats a multiple-site insertion or deletion as a sequence of independent events rather than a single event. While this is true, we have found that under many circumstances it is better to incorporate gap information inadequately than to ignore it, at least for topology estimation. We propose an extension to a class of nucleotide substitution models to incorporate the gap character and show that, for data sets (both real and simulated) with short and medium gaps, these models do lead to effective use of the information contained within insertions and deletions. We also implement an ad hoc method in which the likelihood at columns containing multiple-site gaps is downweighted in order to avoid giving them undue influence. The precision of the estimated tree, assessed using Markov chain Monte Carlo techniques to find the posterior distribution over tree space, improves under these five-state models compared with standard methods which effectively ignore gaps.

Studies on Scenedesmus acutus growth. I effect of autotrophic and mixotrophic conditions on the growth of Scenedesmus acutus (1982)

Among sugars, glucose and mannose were found to be the most suitable substrates for mixotrophic growth, uptake of galactose and its influence on growth was negligible, and sucrose and fructose occupied intermediary positions. The optimum temperature for sugar uptake was 30 degrees C, both under light and in darkness. Enhancement in the photosynthetic oxygen-evolution rate, based on the utilization of substrates, was foremost in the presence of glucose, followed by mannose, sucrose, and fructose. Industrial by-products such as sugarcane molasses also were utilized to increase the algal growth under mixotrophic conditions. A maximum yield in biomass was obtained subsequent to the combined supply of sugarcane molasses with carbon dioxide to indoor as well as outdoor mixotrophic cultures. Doubling the carbon dioxide supply alone above a certain level, under autotrophic and mixotrophic outdoor conditions, did not produce a pronounced increase in the algal growth rate. The results on autotrophic and mixotrophic growth variations are discussed in the article.
Determination of the instrument function of a grating spectrometer by using white-light interferometry (1997)

We determined the instrument function or the response function of a grating spectrometer with finite slit widths in conditions of partial coherent illumination, by using a spectral-interference technique with white light. A Michelson interferometer of variable path delay is used to produce the spectral-interference fringes of required spacing. By deconvolution of the spectral visibility data for various exit and entrance slit widths, we have determined the exact form and frequency width of the instrument function for the spectrometer as well as the working region of the spectrometer for the least distorted output spectrum.
