Wind tunnel experiments on the flow over rectangular cavities at subsonic and transonic speeds (1964)

Measurements have been made of the time average and unsteady pressures acting on the roof and behind a series of rectangular cavities set in the roof of the 2 ft x 1tr ft transonic tunnel.
It was found that the unsteady pressures contain both random and periodic components. The random component predominates in the shallower cavities (length/depth ratio> 4) and is most intense near the rear wall. The periodioc component predominates in the deeper cavities (length/depth ratio < 4) and may form standing wave patterns. It is suggested that the periodic component is due to an acoustic resonance within the cavity excited by a phenomenon similar to th at causing edge-tones. It may be suppressed by fixing a small spoiler at the front of the cavity.
Phenylethanolamine N-methyltransferase-containing neurons in rat retina: immunohistochemistry, immunochemistry, and molecular biology (1986)

We sought to characterize in detail neurons in rat retina that contain phenylethanolamine N-methyltransferase (PNMT), the epinephrine biosynthetic enzyme. Cell bodies and processes of PNMT-containing neurons in retina were identified by immunohistochemistry. The coexistence of other catecholamine biosynthetic enzymes in the same cells was also investigated. Biochemical, molecular biological and immunochemical methods were applied to determine whether retinal PNMT is similar to the adrenal enzyme, since regulation of PNMT in retina and adrenal appears to be different. The results show that there are two types of PNMT-containing cells: those containing PNMT exclusively and those containing PNMT with two other catecholamine-synthesizing enzymes, tyrosine hydroxylase (TH) and aromatic L-amino acid decarboxylase (AADC), but not dopamine beta-hydroxylase (DBH). PNMT-only cell bodies are localized in the inner nuclear layer (INL) and the ganglion cell layer (GCL). Their processes are observed in outer and inner strata of the inner plexiform layer (IPL). Only a small fraction of PNMT neurons in INL also contain TH and AADC. These cells send their processes to the adjacent stratum of the IPL. Antibodies to bovine adrenal DBH, however, fail to localize DBH in any rat retinal cells. Immunochemical titration shows that PNMT from both retina and adrenal gland has the same immunoreactivity. Furthermore, a PNMT-cDNA probe hybridizes equally with PNMT-mRNA isolated from both the retina and the adrenal gland. These results indicate that PNMT is identical in these tissues.
Color filter array demosaicking: New method and performance measures (2003)

Single-sensor digital cameras capture imagery by covering the sensor surface with a color filter array (CFA) such that each sensor pixel only samples one of three primary color values. To render a full-color image, an interpolation process, commonly referred to as CFA demosaicking, is required to estimate the other two missing color values at each pixel. In this paper, we present two contributions to the CFA demosaicking: a new and improved CFA demosaicking method for producing high quality color images and new image measures for quantifying the performance of demosaicking methods. The proposed demosaicking method consists of two successive steps: an interpolation step that estimates missing color values by exploiting spatial and spectral correlations among neighboring pixels, and a post-processing step that suppresses noticeable demosaicking artifacts by adaptive median filtering. Moreover, in recognition of the limitations of current image measures, we propose two types of image measures to quantify the performance of different demosaicking methods; the first type evaluates the fidelity of demosaicked images by computing the peak signal-to-noise ratio and CIELAB DeltaE(*)(ab) for edge and smooth regions separately, and the second type accounts for one major demosaicking artifact-zipper effect. We gauge the proposed demosaicking method and image measures using several existing methods as benchmarks, and demonstrate their efficacy using a variety of test images.
Error Detection in Laser Beam Melting Systems by High Resolution Imaging (2012)

Laser Beam Melting as a member of Additive Manufacturing processes allows the fabrication of three-dimensional metallic parts with almost unlimited geometrical complexity and very good mechanical properties. However, its potential in areas of application such as aerospace or medicine has not yet been exploited due to the lack of process stability and quality management. For that reason samples with pre-defined process irregularities are built and the resulting errors are detected using high-resolution imaging. This paper presents an overview of typical process errors and proposes a catalog of measures to reduce process breakdowns. Based on this systematical summary a future contribution to quality assurance and process documentation is aspired.

A novel method for poly(A) fractionation reveals a large population of mRNAs with a short poly(A) tail in mammalian cells (2007)

The length of the poly(A) tail of an mRNA plays an important role in translational efficiency, mRNA stability and mRNA degradation. Regulated polyadenylation and deadenylation of specific mRNAs is involved in oogenesis, embryonic development, spermatogenesis, cell cycle progression and synaptic plasticity. Here we report a new technique to analyse the length of poly(A) tails and to separate a mixed population of mRNAs into fractions dependent on the length of their poly(A) tails. The method can be performed on crude lysate or total RNA, is fast, highly reproducible and minor changes in poly(A) tail length distribution are easily detected. We validated the method by analysing mRNAs known to undergo cytoplasmic polyadenylation during Xenopus laevis oocyte maturation. We then separated RNA from NIH3T3 cells into two fractions with short and long poly(A) tails and compared them by microarray analysis. In combination with the validation experiments, the results indicate that approximately 25% of the expressed genes have a poly(A) tail of less than 30 residues in a significant percentage of their transcripts.

Scheduling Algorithm: Tasks Scheduling Algorithm for Multiple Processors with Dynamic Reassignment (2008)

Distributed computing systems [DCSs] offer the potential for improved performance and resource sharing. To make the best use of the computational power available, it is essential to assign the tasks dynamically to that processor whose characteristics are most appropriate for the execution of the tasks in distributed processing system. We have developed a mathematical model for allocating “M” tasks of distributed program to “N” multiple processors ( M > N ) that minimizes the total cost of the program. Relocating the tasks from one processor to another at certain points during the course of execution of the program that contributes to the total cost of the running program has been taken into account. Phasewise execution cost [EC], intertask communication cost [ITCT], residence cost [RC] of each task on different processors, and relocation cost [REC] for each task have been considered while preparing a dynamic tasks allocation model. The present model is suitable for arbitrary number of phases and processors with random program structure.
Synthesis and antimycotic activity of some benzyloxyimino compounds. (1987)

Some benzyloxyimio compounds, related to oxiconazole and having a 1H-indole or 1H-benzimidazole moiety, have been synthesized and tested in vitro for their antimycotic activity against Candida tropicalis and C. albicans. The most active was showed to be 0-(2,4-dichlorobenzyl)-1-benzyl-5-nitro-1H-benzimidazole-2-carboxaldehyd e oxime (MIC: 25 micrograms/ml against both microorganisms). A structural feature important for the biological activity of the series appears to be presence of a benzimidazole nucleus substituted by an electron withdrawing group.
Instabilities in the near wake of a rod with an anchored flame (2002)

Turbulent combustion can involve the interaction of flame dynamics, flow structures and acoustic instabilities and many problems remain to be solved. A study of the anomalous 'intrinsic' instability of premixed flames anchored to a rod shows that this instability results in fact from acoustic forcing of the downstream wake. This is shown by tomographic visualizations and by correlations between pressure fluctuations in the combustion chamber and various signals issuing from laser tomography, laser anemometry and deflectometry in the near wake.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
A server-based real-time privacy protection scheme against video surveillance by Unmanned Aerial Systems (2014)

Unmanned Aerial Systems (UAS) have raised a great concern on privacy recently. A practical method to protect privacy is needed for adopting UAS in civilian airspace. This paper examines the privacy policies, filtering strategies, existing techniques, then proposes a novel method based on the encrypted video stream and the cloud-based privacy servers. In this scheme, all video surveillance images are initially encrypted, then delivered to a privacy server. The privacy server decrypts the video using the shared key with the camera, and filters the image according to the privacy policy specified for the surveyed region. The sanitized video is delivered to the surveillance operator or anyone on the Internet who is authorized. In a larger system composed of multiple cameras and multiple privacy servers, the keys can be distributed using Kerberos protocol. With this method the privacy policy can be changed on demand in real-time and there is no need for a costly on-board processing unit. By utilizing the cloud-based servers, advanced image processing algorithms and new filtering algorithms can be applied immediately without upgrading the camera software. This method is cost-efficient and promotes video sharing among multiple subscribers, thus it can spur wide adoption.
The full stature of the crossbar tandem switching system (1956)

CROSSBAR tandem is a relatively young switching system. It first went into service in 1941. Its original role was well defined although, in retrospect, severely limited; it was to take over in large metropolitan areas the functions of the panel-type office selector tandem system, even as the no. 1 crossbar system1 took over from the local panel central office. However, even at that early date, its latent potentialities for a broader field of usefulness were appreciated. This appreciation could not then be implemented because during World War II development of telephone switching facilities at Bell Telephone Laboratories came to a near standstill. The needs of national defense transformed switching development engineers almost overnight into designers and teachers of radar, sonar, etc. True, there followed the great postwar surge of switching development activities but these, in turn, involved new systems urgently needed to start customer and operator nation-wide dialing.1 This period saw the development of the no. 5 crossbar local switching system,2 the automatic message accounting (AMA) system,3 and the 4A crossbar long-distance switching system.4 In view of this tremendous development program of new systems, the available development talent had to be practically rationed, and so only a moderate amount of effort could be applied to the crossbar tandem system to increase its scope of usefulness. The outcome of this effort and the basic description of the crossbar tandem system were presented in 1950.5 The closing paragraph of this 1950 paper was the following statement: “An extensive development program is now in progress to incorporate new features which will still further enhance the usefulness of crossbar tandem in the rapid expansion of automatic switching in the Bell Telephone System.” By now, this extensive development program referred to is nearing completion, and it is the purpose of the present paper to highlight the significant new features embodied in the 1956 design version of the crossbar tandem system.
Amino Acid Profile of High Seed Protein Soybean (1994)

Soybean [ Glycine max (L.) Merr.] is used extensively to meet the protein needs of animals and humans. Although a good source of protein, soybean's nutritional value is limited by low concentrations of sulfur‐containing amino acids (i.e., methionine and cysteine). Thus, it is often necessary to supplement diets with synthetic amino acids, a practice that can be expensive and adds complexity to the diet formulation process. The objective of this study was to determine if amino acid concentrations in recent high protein germplasm releases differ from those in normal protein cultivars. The high protein (HP) lines BARC‐6, BARC‐7, BARC‐8, and BARC‐9 and a normal protein check, either Essex or Manokin were grown in eight different environments from 1989 to 1991. Seed was analyzed for amino acid concentrations, protein, oil, crude fiber, ash, carbohydrate, and moisture. Protein concentration of HP lines ranged from 495 to 530 g kg −1 . The HP lines were lower in oil, crude fiber, and carbohydrate compared to the checks. Concentrations of 14 of the 17 amino acids differed among entries. Concentration of cysteine of BARC‐8, 13.7 g kg −1 , was higher than any other entry. Methionine concentration of BARC‐7 (10.8 g kg −1 ) and lysine concentration of BARC‐9 (55.0 g kg −1 ) were significantly lower than the checks. Feeding trials are necessary to determine the practical significance of these amino acid differences.

[VENOUS THROMBOSIS OF THE LEFT OVARIAN AND EXTENSION TO THE RENAL VEIN]. (2016)

Ovarian vein thrombosis is a rare, but potentially serious postpartum complication. In 80% of the cases, it occurs on the right side and in less than 6% on the left side; it is bilateral in 14% of cases. The usual clinical features include abdominal pain, fever and leucocytosis. However, the diagnosis is often complicated by other non specific signs and symptoms. Ovarian vein thrombosis may cause sepsis, pulmonary thromboembolism, and thrombosis of the inferior vena cava and the renal vein. The diagnosis can be established by CT scan or nuclear magnetic resonance imaging, which has a high sensitivity and specificity. Treatment for the ovarian vein thrombosis includes antibiotics and anticoagulation. The complications can sometimes be surgically managed. Prompt diagnosis and treatment can decrease the morbidity and the mortality. Nowadays, the fatal issue is rare as the appropriate treatment is quickly instaured.
Classifying False Positive Static Checker Alarms in Continuous Integration Using Convolutional Neural Networks (2019)

Static code analysis in Continuous Integration (CI) environment can significantly improve the quality of a software system because it enables early detection of defects without any test executions or user interactions. However, being a conservative over-approximation of system behaviours, static analysis also produces a large number of false positive alarms, identification of which takes up valuable developer time. We present an automated classifier based on Convolutional Neural Networks (CNNs). We hypothesise that many false positive alarms can be classified by identifying specific lexical patterns in the parts of the code that raised the alarm: human engineers adopt a similar tactic. We train a CNN based classifier to learn and detect these lexical patterns, using a total of about 10K historical static analysis alarms generated by six static analysis checkers for over 27 million LOC, and their labels assigned by actual developers. The results of our empirical evaluation suggest that our classifier can be highly effective for identifying false positive alarms, with the average precision across all six checkers of 79.72%.
Nanoporous High Surface Area Silicas With Chelating Groups For Heavy Metal Ion Adsorption From Aqueous Solution (2010)

Nanoporous high surface area silicas are an ideal substrate for the design of materials with useful properties via chemical surface modification. The adsorption of heavy metals for contaminated water detoxification is one potential application. In this work we have used three different kinds of silica substrates with varying pore structures; commercially available narrow pore and wide pore silica gels, as well as surfactant templated mesoporous SBA-15 exhibiting a relatively narrow pore size distribution. These silicas have each been subjected to post-synthesis modification with an organosilane consisting of ethylenediamine triacetic acid functionalities for chelation/adsorption of metal ions from aqueous solution. The surface modified materials have been characterized by N2 adsorption for the determination of surface area and pore size distribution and FTIR spectrometry to probe metal ion - surface bonding interactions with the help of computational calculations. Metal ion adsorption isotherms for Hg(II), Cd(II), Cu(II), Sr(II) and Cr(III) are reported. Previous studies have shown that postsynthesis modification of narrow pore silicas results in a significant reduction of surface area, with dramatically reduced adsorption capacity. In this work chemical surface modification has been achieved with little to no reduction in surface area, thus adsorption capacity remains high even for narrow pore silicas. Very large adsorption capacities, approaching one gram Hg(Il)/gram of silica have been achieved. Diffuse reflectance FTIR spectrometry show changes after metal adsorption indicating specific metal - organosilane interactions are responsible for adsorption.
Preparation of Some 6-Substituted 2,2-Dimethyl- and 2,2- and 2,4-Diphenyl-naphtho[1,2-b]pyrans (1998)

6-Chloro-, 6-bromo-, and 6-methyl-2,2-dimethyl-, and -2,2- and -2,4-diphenyl-naphtho[1,2-b]pyrans are prepared from the appropriate 4-substituted 2H-naphtho[1,2-b]pyran-2-ones and either methylmagnesium iodide or phenylmagnesium bromide; some related compounds and derivatives are also prepared and dimerisation of cylized products from the methylmagnesium iodide reactions affords dimers including a relative of isolapachenole through addition reactions of the intermediate carbonium ion.
Las otras hemerotecas canarias (1998)

En un numero anterior de la revista Latina (febrero de 1998) se incluia un trabajo sobre la hemeroteca canaria de la Universidad de La Laguna, que se complementa ahora con el analisis del resto de las importantes hemerotecas existentes en las islas. Canarias posee importantes hemerotecas que han salvado la coleccion de publicaciones periodicas de las islas. La Hemeroteca del Museo Canario en Las Palmas tiene mas de 1.000 titulos de publicaciones periodicas, y la mejor coleccion de periodicos palmeros se encuentra en la Sociedad Cosmologica de Santa Cruz de La Palma. La Hemeroteca Municipal de Santa Cruz cuenta con unos 500 titulos y la coleccion completa del Semanario Miscelaneo, primer periodico de las islas. Como ya comprobamos, la Universidad de La Laguna posee tambien una de las mas importantes de las colecciones hemerograficas de las islas; pese a ello el conocimiento de los fondos documentales y hemerograficos es reducido con escasos y poco fiables catalogos.
High temperature oxidation of metal, alloy and cermet powders in HVOF spraying process (2004)

In thermal spraying, the coatings, alloys and metals oxidise during the spraying process. Oxidation often results in a decrease in the mechanical and corrosion properties of the coating. In this study, oxidation of HVOF coatings is examined.\n\nIn the beginning of the study, the HVOF spraying process is analysed, including the combustion process, gas temperature, oxygen concentration, gas velocity, and gas momentum. Temperature and velocity of the spray particles are measured. Thermodynamic and kinetic equations of metal oxidation are introduced. In the experimental part of the work, calculations and coating experiments were carried out. Thermodynamic calculations of metal oxidation were done in the HVOF spray gun environment using different fuel/oxygen ratios, fuel quality and metals. The metal oxidation calculations were performed with HSC thermodynamic software.\n\nThe thermodynamic calculations showed that Ni and Co can be sprayed without any oxidation in the HVOF gun nozzle whereas Cr, Ti, Al and Mg are always oxidised. No significant differences were found in the oxidizing potential of fuels such as H2 and kerosene.\n\nIn the spraying experiments, oxidation of WC-Co17 and NiCr80/20 coatings was studied. It was shown experimentally that the short process dwell time does not enable coatings to oxidise completely. It was also found that spray powder oxidation occurs in three steps. First, primarily in the HVOF gun nozzle, second, to a small extent in the plume and third, hardly at all on the surface being coated.\n\nThe thermodynamic calculations, reaction kinetics and experimental work showed that oxidation of spray powder is a complex phenomenon involving selective and volatile oxidation, and formation of solid oxide. Oxidation of the coating is strongly related to the temperature of the particles and combustion gas. Oxidation of the spray powder can take place in solid or molten state.\n\nExperimental work showed that the oxidation processes in the HVOF spray process can not be completely prevented, but can be controlled. The degree of oxidation is reduced by lowering the temperature of the flame, by using a higher gas velocity and density, and employing effective substrate cooling.
