Ascites in poultry (1993)

Research on ascites occurring in meat-type chickens reared at moderate and low altitude has shown that the pathogenesis is similar to that of the high altitude disease. Pulmonary hypertension (PH) caused by increased blood flow or increased resistance to flow in the lung results in right ventricular hypertrophy (RVH), valvular insufficiency, increased venous pressure and ascites. The structure of the avian heart, with its thin-walled right ventricle and muscular right atrioventricular valve, allows PH to induce heart failure quickly. The sudden increase in pulmonary hypertension syndrome (PHS) in meat-type chickens in the 1980s was associated with a rapid increase in growth rate and feed conversion. This was a result of a combination of genetic selection for fast-growing, heavy broilers with low feed conversion and a more dense, high caloric, pelleted food that supplied all the nutrients required for rapid growth and encouraged a high nutrient intake. PHS in meat-type chickens is usually primary pulmonary hypertension, that is, PH that occurs without evidence of prior heart or lung disease that could account for the increase in blood flow or resistance to flow that results in the increased pressure in the pulmonary arteries. The lungs of birds are firm and fixed in the thoracic cavity and they do not expand to draw air into the lung. The blood and air capillaries form a rigid network that allows only minimal expansion of the blood capillaries when more blood flow is required. Air is moved through the lung by abdominal movement which draws air in and out of the air sacs. The anatomy and physiology of the avian respiratory system are important in the susceptibility of meat-type chickens to PHS. The small stature of the modern meat-type chicken, the large, heavy breast mass, the pressure from abdominal contents on air sacs, and the small lung volume compared to body weight, may all be involved in the increased incidence of PHS. There is limited space for blood flow in the avian lung. Factors that increase blood flow or increase resistance to flow are additive. Increased blood viscosity caused by the polycythaemia of hypoxia, or increased erythrocyte rigidity of high Na (+), are more likely to produce PH in fast-growing than in slow-growing birds. Increased flow due to cold exposure is also additive. Ascites caused by PH is a production-related disease at low altitude. It can be prevented easily by restricting growth rate. It is possible that some meat-type chickens of the phenotype we have created have reached the limit of blood flow through their lungs and that future improvements in growth rate will only be possible if the lung and abdominal cavity capacities are enlarged.
[Connection between Helicobacter pylori infection and chronic gastrointestinal urticaria]. (1996)

Chronic urticaria is a disease of unknown etiology. One type of the disease is accompanied by gastrointestinal complaints. The aim of the present study was to determine the prevalence of Helicobacter pylori (H. pylori) infection in patients with chronic urticaria, and measure the effectiveness of eradication of HP on the skin disease. Patients with chronic urticaria of other origin were excluded from the study. Forty patients out of 95 studied fulfilled the criteria of gastrointestinal urticaria. H. pylori was measured both by measuring H. pylori-specific IgG in the serum and by direct staining of biopsy specimen taken upon endoscopy prior to and after the treatment. Seventeen patients out of 40 with gastrointestinal urticaria were H. pylori positive which incidence (43%) is not higher than that of the age matched healthy population in Hungary. H. pylori positive patients were treated with amoxycillin (4 x 500 mg/die), bismuth subsalicilate (3 x 512 mg/die) and metronidazole (2 x 500 mg/die) for two weeks, respectively, and those remaining positive were treated by omeprazole (2 x 20 mg/die) and amoxycillin for additional two weeks. Eradication of HP infection was successful in all patients. Follow-up was conducted from 6-18 months for urticaria (frequency, duration) and antihistamine drug requirement. Chronic urticaria did not disappeared after the eradication of H. pylori, but there was a significant reduction both in frequency, duration of urticaria and the need for antihistamine therapy after eradication of H. pylori. It was concluded that H. pylorilinfection has no effect on the course of chronic urticaria. Reduction in frequency of urticaria symptoms and reduction of antihistamine requirement is partly due to the natural course of the disease and likely due to the altered bacterial flora of the gut following the combined antibiotic treatment.
Usages of DASH for rich media services (2011)

In recent years, audio-visual distribution over Internet has witnessed the growing usage of HTTP based delivery systems. While these systems have their drawbacks for some use-cases, they also have many advantages, the most important one being reusing the existing delivery infrastructure such as HTTP servers, proxies and caches. The MPEG group has started the standardization of the Dynamic Adaptive Streaming over HTTP (DASH) of major transport formats, MPEG-2 TS and ISO Base Media File, and mostly focuses on audio, video and subtitle formats. We believe Rich Media services have a role to play in this landscape, as a presentation layer for the audio-visual content first, but also as a dedicated media in the DASH content for real-time media-synchronized interactive services. In this paper, we present a study on usages of DASH for Rich Media Services.
Progression of Histomonosis in Commercial Chickens Following Experimental Infection with an<i>In Vitro</i>Propagated Clonal Culture of<i>Histomonas meleagridis</i> (2011)

Four commercial strains of chickens, namely, ISA brown leghorn (ISA), TETRA-SL brown (TETRA-SL), Lohmann brown (LB), and Lohmann LSL (LSL), were infected with a well-defined clonal culture of Histomonas meleagridis (H. meleagridis/Turkey/Austria/2922-C6/04) to investigate their susceptibility to histomonosis. Each group included 16 chickens, which were housed under the same conditions in separate pens. All chickens were infected with 10(4) histomonads orally and intracloacally at 14 days of age. No mortality or clinical signs were observed during the experiment in all birds. Three birds of each chicken strain were euthanatized on days 4, 7, 10, 14, and 21 postinfection. Incidence of histomonosis on the basis of cecal lesions was found to be 64.00% in TETRA-SL, 62.50% in LB, 53.12% in LSL, and 43.75% in ISA chickens. Fewer lesions were noticed in livers than in ceca, with an incidence of 15.62% in TETRA-SL, 9.37% in LB, and 3.12% in ISA chickens. No liver lesions were found in the LSL chickens. Statistical analysis revealed that there was no significant difference (P > 0.05) in susceptibility to experimental H. meleagridis infection based on cecal and liver involvement. Polymerase chain reaction (PCR) and immunohistochemistry were found to be reliable tools to confirm the presence of histomonads and changes in the ceca. However, some negative PCR results were recorded from the livers despite the presence of macroscopic lesions. Additionally, DNA of H. meleagridis was detected by PCR in a few of the lungs, but immunohistochemistry was negative. Nucleic acid of the protozoan parasite was not detected in samples from kidney, brain, spleen, or bursa of Fabricius. Altogether, the high susceptibility of commercial chicken lines to histomonosis could be demonstrated and characterized by severe lesions in the ceca and insignificant involvement of the liver, approaching a maximum on days 7-14 postinfection.
Anatomical, physiological and molecular properties of Martinotti cells in the somatosensory cortex of the juvenile rat (2004)

Whole-cell patch-clamp recordings followed by histochemical staining and single-cell RT-PCR were obtained from 180 Martinotti interneurones located in layers II to VI of the somatosensory cortex of Wistar rats (P13-P16) in order to examine their anatomical, electrophysiological and molecular properties. Martinotti cells (MCs) mostly displayed ovoid-shaped somata, bitufted dendritic morphologies, and axons with characteristic spiny boutons projecting to layer I and spreading horizontally across neighbouring columns more than 1 mm. Electron microscopic examination of MC boutons revealed that all synapses were symmetrical and most synapses (71%) were formed onto dendritic shafts. MCs were found to contact tuft, apical and basal dendrites in multiple neocortical layers: layer II/III MCs targeted mostly layer I and to a lesser degree layer II/III; layer IV MCs targeted mostly layer IV and to a lesser degree layer I; layer V and VI MCs targeted mostly layer IV and layer I and to a lesser degree the layer in which their somata was located. MCs typically displayed spike train accommodation (90%; n = 127) in response to depolarizing somatic current injections, but some displayed non-accommodating (8%) and a few displayed irregular spiking responses (2%). Some accommodating and irregular spiking MCs also responded initially with bursts (17%). Accommodating responses were found in all layers, non-accommodating mostly in upper layers and bursting mostly in layer V. Single-cell multiplex RT-PCR performed on 63 MCs located throughout layers II-VI, revealed that all MCs were somatostatin (SOM) positive, and negative for parvalbumin (PV) as well as vasoactive intestinal peptide (VIP). Calbindin (CB), calretinin (CR), neuropeptide Y (NPY) and cholecystokinin (CCK) were co- expressed with SOM in some MCs. Some layer-specific trends seem to exist. Finally, 24 accommodating MCs were examined for the expression of 26 ion channel genes. The ion channels with the highest expression in these MCs were (from highest to lowest); Cabeta1, Kv3.3, HCN4, Cabeta4, Kv3.2, Kv3.1, Kv2.1, HCN3, Caalpha1G, Kv3.4, Kv4.2, Kv1.1 and HCN2. In summary, this study provides the first detailed analysis of the anatomical, electrophysiological and molecular properties of Martinotti cells located in different neocortical layers. It is proposed that MCs are crucial interneurones for feedback inhibition in and between neocortical layers and columns.
Translocation (12;22) (p13;q11) in myeloproliferative disorders results in fusion of the ETS-like TEL gene on 12p13 to the MN1 gene on 22q11. (1995)

In myeloid and lymphoid leukemias recurrent chromosomal aberrations can be detected in chromosome region 12p13. We characterized the genes involved in t(12;22) (p13;q11) in two patients with myeloid leukemia and one with myelodysplastic syndrome (MDS). MN1, a gene on chromosome 22q11 was shown to be fused to TEL, a member of the family of ETS transcription factors on chromosome 12p13. The translocation results in transcription of the reciprocal fusion mRNAs, MN1-TEL and TEL-MN1, of which MN1-TEL is likely to encode an aberrant transcription factor containing the ETS DNA-binding domain of TEL. In addition to fusion of TEL to the PDGF beta receptor in t(5;12) in chronic myelomonocytic leukemia (CMML), our data suggest that the involvement of this protein in myeloid leukemogenesis could be dual; its isolated protein-protein dimerization and DNA-binding domains may be crucial for the oncogenic activation of functionally different fusion proteins.
Surface Charge Considerations in the Pitting of Ion‐Implanted Aluminum (1988)

The relationship between the pitting potential of an oxide‐covered metal, and the pH of zero charge of its oxide, , was studied by ion implanting aluminum (99.999% purity) with elements whose oxides were of known (Mg, Al, Si, Cr, Zr, Nb, Mo, and Zn). The results showed that all the implants chosen because of the low of their oxides (Si, Cr, Zr, Nb, and Mo) produced binary surface alloys that had higher (more positive) pitting potentials than aluminum. The implants chosen because of the high of their oxides (Zn and Mg) produced binary surface alloys that had pitting potentials that were either lower than (Zn) or the same as (Mg) that of aluminum. The Mg‐Al surface alloy results are explained by selective leaching of the Mg from the oxide. The implantation of aluminum into aluminum had no effect on the pitting potential, indicating that the increased and decreased pitting potentials observed for the other implants was a chemical effect.

Enhanced light extraction and tunable chromaticity in white organic light-emitting devices with ZnO nanopillars (2016)

Robust ZnO nanopillars (NPs) with well-controlled morphology were directly prepared on the glass surface of a white organic light-emitting diode (WOLED) substrate using a hydrothermal process. The NPs can effectively recover light loss in the glass substrate and the current efficiency of the device increased by 20%. In addition, the chromaticity coordinates of the WOLED can be tuned by selecting the dimensions of the ZnO NPs. As a consequence, it is possible to produce a solar light spectrum using this technique. Furthermore, the nanotextured glass surface was superhydrophobic, which caused self-cleaning properties to the surface and help maintain maximum light output.
Accent recognition using i-vector, Gaussian Mean Supervector and Gaussian posterior probability supervector for spontaneous telephone speech (2013)

In this paper, three utterance modelling approaches, namely Gaussian Mean Supervector (GMS), i-vector and Gaussian Posterior Probability Supervector (GPPS), are applied to the accent recognition problem. For each utterance modeling method, three different classifiers, namely the Support Vector Machine (SVM), the Naive Bayesian Classifier (NBC) and the Sparse Representation Classifier (SRC), are employed to find out suitable matches between the utterance modelling schemes and the classifiers. The evaluation database is formed by using English utterances of speakers whose native languages are Russian, Hindi, American English, Thai, Vietnamese and Cantonese. These utterances are drawn from the National Institute of Standards and Technology (NIST) 2008 Speaker Recognition Evaluation (SRE) database. The study results show that GPPS and i-vector are more effective than GMS in this accent recognition task. It is also concluded that among the employed classifiers, the best matches for i-vector and GPPS are SVM and SRC, respectively.
A Supply Chain Configuration Tool (1997)

Abstract The manufacturing of complex products often involves the assembly of other products, or sub-assemblies. Furthermore, these sub-assemblies may be manufactured by different suppliers. As a result, the specification of the assembly process for the final product contains relationships between multiple supply chain components, including business entities, manufacturing processes, products, and parts. This specification, involving the coordination and arrangement of supply chain components to support final product assembly, is referred to as a supply chain configuration. A supply chain configuration tool is used to recognize and modify the relationships between these components. Users of this tool may be engineers, purchasing agents, program managers, or other personnel concerned with the configuration’s dependencies. The focus of this paper is on the development of such a tool and its use from the perspective of a purchasing agent.
Verifying and enforcing network paths with icing (2011)

We describe a new networking primitive, called a Path Verification Mechanism (pvm). There has been much recent work about how senders and receivers express policies about the paths that their packets take. For instance, a company might want fine-grained control over which providers carry which traffic between its branch offices, or a receiver may want traffic sent to it to travel through an intrusion detection service.
A NEW GENERATION CHEMICAL FLOODING SIMULATOR (2005)

The premise of this research is that a general-purpose reservoir simulator for several improved oil recovery processes can and should be developed so that high-resolution simulations of a variety of very large and difficult problems can be achieved using state-of-the-art algorithms and computers. Such a simulator is not currently available to the industry. The goal of this proposed research is to develop a new-generation chemical flooding simulator that is capable of efficiently and accurately simulating oil reservoirs with at least a million gridblocks in less than one day on massively parallel computers. Task 1 is the formulation and development of solution scheme, Task 2 is the implementation of the chemical module, and Task 3 is validation and application. In this final report, we will detail our progress on Tasks 1 through 3 of the project.
Color histogram features based image classification in content-based image retrieval systems (2008)

In content-based image retrieval systems (CBIR) the most efficient and simple searches are the color based searches. Although this methods can be improved if some prepocessing steps are used. In this paper one of the prepocessing algorithms, the image classification is analyzed. In CBIR image classification has to be computationally fast and efficient. In this paper a new approach is introduced, which based on low level image histogram features. The main advantage of this method is the very quick generation and comparison of the applied feature vectors.
Development of High-Definition Video Copy Equipment (1986)

High-definition video copy equipment with picture quality almost simulating photo prints has been developed. A sublimation dye thermal transfer method is used to give prints which are A5 in size and have a printing resolution of 8 dots/mm.
Miscible Fluid Displacement in Porous Media (1958)

Published in Petroleum Transactions, AIME, Volume 213, 1958, pages 76–79. Abstract An experimental investigation of miscible fluid displacement has been made in linear porous media under highly adverse mobility ratio conditions. Various refined oils were displaced at field rates by liquid propane in both horizontal and vertical models 9 to 36 ft in length. In horizontal tests, mixed zones or transition zones form between the two liquids early in the displacements. Initially, the zones grow rapidly. In 2-in. diameter models, the mixed regions become nearly stable zones from 6- to 20-ft long. From then on these quasi-stable zones apparently grow only by molecular diffusion. The lengths of the quasi-stable zones appear to be almost independent of the core material in which displacements are made and increase with increasing rates of injection and oil/solvent viscosity ratios. The lengths of the quasi-stable zones measured in 2-in. diameter models at viscosity ratios and injection rates anticipated in the field indicate that essentially piston-like displacements of oil by solvent would occur. However, the mixed zone lengths increase markedly as the model diameter increases. In vertical displacements controlled by gravity drainage, only short transition zones form. The entire lengths of these zones can be accounted for by molecular diffusion. Therefore, in reservoirs having characteristics allowing a high degree of gravity drainage, nearly complete oil recovery should be attainable by miscible fluid displacement. Introduction The oil industry is faced with an ever increasing cost for finding new oil reservoirs. This, coupled with the fact that conventional methods of oil recovery usually leave from 1 to 3 bbl of oil in the ground for every barrel produced, has aroused considerable interest in developing more efficient methods. An integral part of the mechanism of many of these new methods of recovery is a miscible fluid displacement in which oil is displaced by a much less viscous material such as liquid propane. A number of investigators have explored the mechanics of miscible fluid displacement but in the experiments reported many of the important factors have been varied only over a limited range far removed from normal oilfield values. This paper presents the results of an experimental study of oil displacement by liquid propane at field rates from linear, natural-sandstone models of various sizes. Both horizontal and vertical flow tests were made.
Automated measurement of bone-mineral-density (BMD) values of vertebral bones based on X-ray torso CT images (2009)

Bone is one of the most important anatomical structures in humans and osteoporosis is one of the major public health concerns in the world. Osteoporosis is a main target disease of bone, which can be detected by medical image techniques. The purpose of this study is to develop a fully automated computer scheme to measure bone-mineral-density (BMD) values for vertebral trabecular bones. This scheme will aid osteoporosis diagnosis performed using computer tomography (CT) images. This scheme includes the following processing steps: segmentation of the bone region, recognition of the skeletal structures and measurement of the BMD value in vertebral trabecular bone of each vertebral body. The proposed scheme was applied to 20 X-ray torso CT cases to measure the BMD values for vertebral trabecular bones. The experimental results show that the mean and standard deviation of the difference between the BMD values measured by using the proposed method and those measured using a manual segmentation method were 6.93 mg/cm(3) and 6.82 mg/cm(3) respectively. The accuracy of the proposed scheme satisfied the requirement for a computer-aided system used in osteoporosis diagnosis.
High Performance Fluorescent Lamps (1972)

The performance of 24 real fluorescent lamps is evaluated. Many of the lamps comprise one or more of the narrow-band emissions near 450, 540, 610 nm. These colors, when incorporated into a lamp SPD, are shown to lead to extraordinary improvement in CRI and luminance taken together, in color discrimination capability, and in preferred rendering of object colors.

A Compendium of Mutational Signatures of Environmental Agents (2019)

Whole-genome-sequencing (WGS) of human tumors has revealed distinct mutation patterns that hint at the causative origins of cancer. We examined mutational signatures in 324 WGS human-induced pluripotent stem cells exposed to 79 known or suspected environmental carcinogens. Forty-one yielded characteristic substitution mutational signatures. Some were similar to signatures found in human tumors. Additionally, six agents produced double-substitution signatures and eight produced indel signatures. Investigating mutation asymmetries across genome topography revealed fully functional mismatch and transcription-coupled repair pathways. DNA damage induced by environmental mutagens can be resolved by disparate repair and/or replicative pathways, resulting in an assortment of signature outcomes even for a single agent. This compendium of experimentally induced mutational signatures permits further exploration of roles of environmental agents in cancer etiology and underscores how human stem cell DNA is directly vulnerable to environmental agents.
