Automatic hierarchical classification using time-based co-occurrences (2003)

While a tracking system is unaware of the identity of any object it tracks, the identity remains the same for the entire tracking sequence. Our system leverages this information by using accumulated joint cooccurrences of the representations within the sequence to create a hierarchical binary-tree classifier of the representations. This classifier is useful to classify sequences as well as individual instances. We illustrate the use of this method on two separate representations the tracked object's position, movement, and size; and the tracked object's binary motion silhouettes.
PLT versus KLT [transforms] (2003)

In this paper a new class of transforms named Prediction-based Lower triangular Transform (PLT) is introduced for signal compression. The PLT is a nonunitary transform that yields the same coding gain as the Kahunen-Loeve transform (KLT). Unlike KLT, the derivation of PLT does not involve any eigen problem. An M-dimensional PLT can be solved by the Levinson-Durbin recursion formula in O(M/sup 2/). Moreover the complexity of PLT is less than one half of KLT. For AR(1) inputs, the PLT has a closed form expression and needs only (M-1) multiplications.
YAF: yet another flowmeter (2010)

A flow meter generates flow data - which contains information about each connection observed on a network - from a stream of observed packets. Flow meters can be implemented in standalone measurement devices or inline on packet forwarding devices, such as routers. YAF (Yet Another Flowmeter) was created as a reference implementation of an IPFIX Metering and Exporting Process, and to provide a platform for experimentation and rapid deployment of new flow meter capabilities. Significant engineering effort has also gone into ensuring that YAF is a high performance, flexible, stable, and capable flow collector. This paper describes the some of the issues we encountered in designing and implementing YAF, along with some background on some of the technologies that we chose for implementation. In addition we will describe some of our experiences in deploying and operating YAF in large-scale networks.

Levothyroxine sodium 0.4 microg/mL in 500 mL 0.9% sodium chloride is stable for 24 hours at room temperature when protected from light.
Phenomenological vector model of microwave reflection from the ocean (1956)

A model of one-way transmission of microwave electromagnetic signals over the ocean surface is developed from experiment. The received signal is described as a vector sum of a constant direct signal, a coherent reflected signal, whose amplitude and phase are fixed by geometry and sea state, and a fluctuating reflected component of random amplitude and phase. By interpreting experimental data in the light of this phenomenological model it has been possible to relate, quantitatively, the coherent and incoherent reflected signal and total signal to geometry and sea state. The results give support to the theoretical expression previously derived by Ament and others relating the coherent reflected signal to "apparent ocean roughness." In addition, the general shape of the curve relating the incoherent scattering to "apparent ocean roughness" has been established and its asymptotic value found.

Fluorescent non-conjugated polymer dots for targeted cell imaging (2016)

Through the chemical crosslinking of the sub-fluorophore, linear non-conjugated polymers can possess strong photoluminescence (PL), which is a very important fluorescence behavior and the non-conjugated polymer dots (PDs) are efficient bio-fluorophores for bio-based applications. Herein, the new type of non-conjugated polyethyleneimine (PEI) PDs was further modified by targeting molecules (folic acid) for a new generation of bio-fluorophores. The free folic acid can quench the PL of PDs by energy transfer, while the conjugated folic acid@PDs (FA@PDs) can still maintain their PL properties to a certain degree. The FA@PDs also possess lower toxicity compared with free PDs, which is possibly due to blocking of the amino groups. Moreover, we investigated the targeted bioimaging applications of the FA@PDs, which gave a very important direction for application of these types of materials.
Design of middleware based grid GIS (2005)

Data distribution of GIS has been realized through WebGIS. With the increasing need of data sharing and GIS, WebGIS can no longer meet this need. The applications of grid computing and middleware technology in GIS lay a foundation for the development of middleware grid GIS. Grid GIS not only makes spatial data distribution, also makes the functional services of GIS distribution. This paper focuses on the functional architecture of grid GIS, and brings forward a functional model of grid GIS. GML and middleware are also important factors in the development of grid GIS, GML is the message carrier in the grid of Web.
Variants of the 3′ Region of the <i>cagA</i> Gene in <i>Helicobacter pylori</i> Isolates from Patients with Different <i>H. pylori</i> -Associated Diseases (1998)

The CagA protein of Helicobacter pylori is an immunogenic antigen of variable size and unknown function that has been associated with increased virulence as well as two mutually exclusive diseases, duodenal ulcer and gastric carcinoma. The 3' region of the cagA gene contains repeated sequences. To determine whether there are structural changes in the 3' region of cagA that predict outcome of H. pylori infection, we examined 155 cagA gene-positive H. pylori isolates from Japanese patients including 50 patients with simple gastritis, 40 with gastric ulcer, 35 with duodenal ulcer, and 30 with gastric cancer. The 3' region of the cagA gene was amplified by PCR followed by sequencing. CagA proteins were detected by immunoblotting using a polyclonal antibody against recombinant CagA. One hundred forty-five strains yielded PCR products of 642 to 651 bp; 10 strains had products of 756 to 813 bp. The sequence of the 3' region of the cagA gene in Japan differs markedly from the primary sequence of cagA genes from Western isolates. Sequence analysis of the PCR products showed four types of primary gene structure (designated types A, B, C, and D) depending on the type and number of repeats. Six of the seven type C strains were found in patients with gastric cancer (P < 0.01 in comparison to noncancer patients). Comparison of type A and type C strains from patients with gastric cancer showed that type C was associated with higher levels of CagA antibody and more severe degrees of atrophy. Differences in cagA genotype may be useful for molecular epidemiology and may provide a marker for differences in virulence among cagA-positive H. pylori strains.
Influence of anaerobic co-digestion of sewage and brewery sludges on biogas production and sludge quality (2007)

This research investigated operating parameters and treatment efficiency for the digestion of sewage and brewery sludge. The prime objective of this study was to enhance the quality of treated sludge for use as agriculture fertilizer and to enhance biogas production, a by-product that can be used as an energy source. Three bench-scale completely stirred tank reactor (CSTR) anaerobic digesters were operated at mesophilic condition (36+/-0.2 degrees C). A mixture of sewage and brewery sludge were used as substrates at ratios of 100:0, 75:25, 50:50, 25:75 and 0:100, based on wet weight basis (w/w). For each digester, the solids retention times (SRT) were 20 days. The organic loading and volatile solids loading were between 1.3-2.2 kg chemical oxygen demand (COD)/m3/day and 0.9-1.5 kg/m3/day, respectively. The digester fed with brewery sludge as co-substrate yielded higher treatment efficiency than sewage sludge alone. The removal efficiencies measured in terms of soluble chemical oxygen demand (SCOD) and total chemical oxygen demands (TCOD) ranged from 40% to 75% and 22% to 35%, respectively. Higher SCOD and TCOD removal efficiencies were obtained when higher fractions of brewery sludge was added to the substrate mixture. Removal efficiency was lowest for sewage sludge alone. Measured volatile solid (VS) reduction ranged from 15% to 20%. Adding a higher fraction of brewery sludge to the mixture increased the VS reduction percentage. The biogas production and methane yield also increased with increase in brewery sludge addition to the digester mixture. The methane content present in biogas of each digester exceeded 70% indicating the system was functioning as an anaerobic process. Likewise the ratio of brewery sewage influenced not only the treatment efficiency but also improved quality of treated sludge by lowering number of pathogen (less than 2 MPN/g of dried sludge) and maintaining a high nutrient concentration of nitrogen (N) 3.2-4.2%, phosphorus (P) 1.9-3.2% and potassium (K) 0.95-0.96%. The heavy metals, chromium (Cr) and copper (Cu) remaining in digested sludge were present at relatively high levels (Cr 1,849-4,230 and Cu 930-2,526 mg/kg dried sludge). The metals were present as organic matter-bound and sulfide-bound fractions that are not soluble and available. The digested sludge could be safely applied to soil as a plant nutrient source, without fecal coliforms or heavy metals risk. A sludge mixture ratio of 25:75 (sewage:brewery), which generated the higher nutrient concentrations (N=4.22%, P=3.20% and K=0.95%), biogas production and treatment efficiency meet the Bangkok Metropolitan Administration (BMA) safety guidelines required for agricultural application. Biogas production and methane at the 25:75 ratio (sewage:brewery) yielded highest amount of VSremoved (0.65 m3/kg) and CODremoved (220 L/kg), respectively.
InGaAs/InP p-i-n photodiodes for lightwave communications at the 0.95-1.65 µm wavelength (1981)

We summarize our work on back-illuminated photodiodes based on the As-Ga-In-P III-V semiconductor system which, with InP substrates, can provide photodetectors to cover the wavelength range of <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">0.93-1.65 \mu</tex> m. LPE layer growth and material purification techniques are described, as well as the fabrication and characterization of p-i-n photodiodes made from these compounds. The relevant device parameters and their optimization are discussed, and the performance of high-bit-rate optical receivers employing the new detectors is noted. Finally, we suggest some areas where further research might lead both to a better understanding of carrier transport in these heterojunction configurations and to improved devices made from them.
Synthese von 5-Azido-3-nitro-ω-brom-acetophenon — einem photoaktivierbaren bifunktionellen Reagenz zur Vernetzung von Biopolymeren / Synthesis of 5-Azido-3-nitro-ω-bromo-acetophenone — a Photochemically Active Bifunctional Reagent for the Cross-Linking of Biopolymers (1976)

The photochemically activatable heterobifunctional reagent 5-azido-3-nitro-omega-bromo-acetophenone (3) was synthesized by condensation of 3,5-dinitrobenzoyl chloride with diethyl malonate, acid-catalyzed decarboxylation of the formed malonester derivative 1 to 3,5-dinitro-acetophenone (2a), selective reduction of one nitro group in 2a to 5-amino-3-nitro-acetophenone (2b) and diazotization to 2c. Nucleophilic displacement of the diazonium group in 2c by sodium azide forms 5-azido-3-nitro-acetophenone (2d) which gives 3 after bromination. Compound 3 is photochemically labile and forms an highly reactive nitrene during ultraviolet irradiation. Since compound 3 is able to alkylate amino- or mercapto-groups of amino acids or nucleosides via its bromoacetyl residue, the bifunctional reagent 3 should cross link proteins or nucleic acids after nitrene generation.
Splitting source code identifiers using Bidirectional LSTM Recurrent Neural Network (2018)

Programmers make rich use of natural language in the source code they write through identifiers and comments. Source code identifiers are selected from a pool of tokens which are strongly related to the meaning, naming conventions, and context. These tokens are often combined to produce more precise and obvious designations. Such multi-part identifiers count for 97% of all naming tokens in the Public Git Archive - the largest dataset of Git repositories to date. We introduce a bidirectional LSTM recurrent neural network to detect subtokens in source code identifiers. We trained that network on 41.7 million distinct splittable identifiers collected from 182,014 open source projects in Public Git Archive, and show that it outperforms several other machine learning models. The proposed network can be used to improve the upstream models which are based on source code identifiers, as well as improving developer experience allowing writing code without switching the keyboard case.
Covalently functionalized amide cross-linked hydrogels from primary amines and polyethylene glycol acyltrifluoroborates (PEG-KATs) (2018)

A new method for the rapid preparation of chemically cross-linked hydrogels based on a multi-arm polyethylene glycol (PEG) bearing potassium acyl trifluoroborate (KAT) functional groups with multi-dentate amines is described. These scaffolds - prepared in aqueous buffer - give strong, transparent hydrogels. At pH 3, the gel formation is complete within seconds, and the reaction rate can be tuned by modulating the pH. Rheology measurements show that the hydrogel properties can be tuned as a function of both the weight percent of solids in the gel and the denticity of amine cross-linker, allowing for predictable formation of gels with desired traits. This process relies on a rapid amide-forming reaction of KATs and in situ generated N-chloroamines. Numerous commercially available amines, including di-, tri- and tetra-functional amines as well as peptides and carbohydrates serve as effective cross-linkers. Monodentate amines included in the gelation mixture are covalently linked into the gel matrix by amide-bonds, allowing gels containing immobilized molecules including dyes, sensors, or biotin amine, to be prepared in a single step from simple starting materials. The ability to induce gelation only upon addition of equimolar amounts of an inexpensive inducer (N-chlorosuccinimide) allows premixed components to be stored as an aqueous solution for weeks and converted to gels on demand.
Binding and Activation of Plasminogen on Immobilized Immunoglobulin G (1989)

We have found that tissue plasminogen activator catalyzes the binding of plasminogen (Pg) to immunoglobulin G (IgG) immobilized on a surface. This enhancement is due to the formation of plasmin, since plasmin treatment of immobilized IgG produced a 20-fold increase in Pg binding. Pg binding is lysine site dependent and reversible. The augmentation of Pg binding by plasmin is specific as other proteases produced significantly less or no effect. Immobilized plasmin-treated IgG also specifically binds Pg in plasma. IgG-immobilized Pg is activated by tissue plasminogen activator, and a significant portion of the plasmin formed remains bound to the IgG. The Pg reactive species in a plasmin-treated IgG digest was identified as the Fab fragment by chromatography utilizing the immobilized high affinity lysine-binding site of plasminogen. Specificity of the interaction was further demonstrated by immunoblot-ligand analysis which demonstrated that the plasmin-derived Fab fragment bound Pg whereas papain-derived Fab or plasmin-derived Fc fragments did not. These data suggest that Pg binds to the new COOH-terminal lysine residue of the plasmin-derived Fab. Pg also binds to an immobilized immune complex following plasmin treatment. These findings indicate that surface-bound IgG localizes plasminogen thus extending the spectrum of activity of the plasmin system to immunologic reactions.
Provisioning technology for automation (2007)

Vendors have recently been offering more products and solutions for IT system management. Fujitsu's Resource is a product that provides an infrastructure for automation to reduce the administrative costs of a complex, large-scale IT system. Although the term is often used to discuss system management, how this technology can be applied to actual systems and what benefits it will provide are not fully understood. Automation entails certain aspects such as monitoring, correcting, and acting. Systemwalker Resource Coordinator provides provisioning technology for self-acting. This paper outlines the provisioning technology of Systemwalker Resource Coordinator and cites several case studies in describing how Systemwalker Resource Coordinator resolves many common issues facing system administrators.
Merkel cell carcinoma: Changing incidence trends (2004)

MCC incidence rates have increased threefold over the 1986-2001 period. Rates are highest in the elderly population. Further etiologic studies and identification of high-risk populations are warranted.
Visual analytics of anomaly detection in large data streams (2008)

Most data streams usually are multi-dimensional, high-speed, and contain massive volumes of continuous information. They are seen in daily applications, such as telephone calls, retail sales, data center performance, and oil production operations. Many analysts want insight into the behavior of this data. They want to catch the exceptions in flight to reveal the causes of the anomalies and to take immediate action. To guide the user in finding the anomalies in the large data stream quickly, we derive a new automated neighborhood threshold marking technique, called AnomalyMarker. This technique is built on cell-based data streams and user-defined thresholds. We extend the scope of the data points around the threshold to include the surrounding areas. The idea is to define a focus area (marked area) which enables users to (1) visually group the interesting data points related to the anomalies (i.e., problems that occur persistently or occasionally) for observing their behavior; (2) discover the factors related to the anomaly by visualizing the correlations between the problem attribute with the attributes of the nearby data items from the entire multi-dimensional data stream. Mining results are quickly presented in graphical representations (i.e., tooltip) for the user to zoom into the problem regions. Different algorithms are introduced which try to optimize the size and extent of the anomaly markers. We have successfully applied this technique to detect data stream anomalies in large real-world enterprise server performance and data center energy management.
Anticalins<sup>®</sup>: the lipocalin family as a novel protein scaffold for the development of next-generation immunotherapies (2007)

Anticalins are engineered ligand-binding proteins based on the human lipocalin scaffold. Their architecture is characterized by a rigid beta-barrel that supports four structurally hypervariable loops. Similar to antibodies, these loops form the natural ligand-binding site, usually for vitamins, hormones or secondary metabolites. Anticalins with novel specificities can be engineered by reshaping this loop region, using targeted random mutagenesis in combination with functional display and guided selection. Several drug candidates with specificities for exogenous low-molecular-weight substances, peptides and even protein targets (e.g., several disease-related cell surface receptors) have been obtained in this way. Owing to their exquisite specificity and high affinity, Anticalins are particularly attractive as antagonists for the manipulation of immune mechanisms, leading to either inhibitory or stimulatory effects. Compared with antibodies, Anticalins offer several practical advantages as they are much smaller, consist of a single polypeptide chain and can be produced easily in microbial expression systems.
Analysis of risk factors for fatal hemorrhage during induction therapy of patients with acute promyelocytic leukemia. (1989)

Acute promyelocytic leukemia (APL), an uncommon subtype of acute myelogenous leukemia (AML), has a high incidence of early hemorrhagic death during induction therapy; however, patients with APL surviving induction and obtaining complete remission have a good prognosis, with a longer remission duration than other subtypes of AML. We sought to determine if changes in selected clinical and laboratory coagulation parameters during induction therapy were significantly associated with fatal hemorrhage in that week, or were predictive of fatal hemorrhage in the following week. The first six weeks of induction therapy were studied in 65 patients, during which time 23 patients (35%) died from hemorrhagic complications. Time intervals analyzed were week 1, week 2, weeks 3 and 4, and weeks 5 and 6. There was no significant difference in the prevalence of severe hypofibrinogenemia (less than 150 mg%), prolongation of the prothrombin time (greater than 14 s), or presence of infection between patients who sustained fatal hemorrhage versus those who did not, for any given time period. The most significant parameter was the inability to obtain a posttransfusion platelet count of over 40,000/microliters in at least one half of the platelet transfusions administered in that week (p less than 0.001). This last parameter was the only variable that was also significantly associated with an increased risk of fatal hemorrhage for the following week (p less than 0.005). Clinical trials investigating management of coagulopathy in APL should evaluate the effect of therapy on response to platelet transfusion as well as on other laboratory parameters.
