Knowledge-based alarm surveillance for TMN (2002)

Alarm surveillance (AS) and alarm correlation (AC) are important functions in telecommunications management network (TMN) especially in heterogeneous communication networks such as public switching systems. This paper focuses on a new methodology for alarm correlation and alarm surveillance by using the deductive model-based and the inductive case-based reasoning technique. This approach is based on the object-oriented description of a network corresponding to international accepted standards and on the availability of expert knowledge about specific faults and resulting alarm situations. Long term analysis and diagnosis are supported by statistical fault hypotheses evaluation not covered explicitly by reasoning techniques. A working prototype has been successfully constructed which proved these alarm correlation principles.
2‐(<i>N</i>‐Methylbenzyl)pyridine: A Potential Liquid Organic Hydrogen Carrier with Fast H<sub>2</sub> Release and Stable Activity in Consecutive Cycles (2017)

The liquid organic hydrogen carrier (LOHC) 2-(N-methylbenzyl)pyridine (MBP) shows good potential for H<sub>2</sub> storage based on reversible hydrogenation and dehydrogenation, with an H<sub>2</sub> storage density of 6.15 wt %. This material and the corresponding perhydro product (H<sub>12</sub> -MBP) are liquids at room temperature. Remarkably, H<sub>2</sub> release is much faster from H<sub>12</sub> -MBP over Pd/C than from the benchmark perhydro benzyltoluene over Pt/C at lower temperatures than 270 °C, owing to the addition of N atom into the benzene ring. Since this positive effect is unfavorable to the hydrogenation reaction, more Ru/Al<sub>2</sub> O<sub>3</sub> catalyst or prolonged reaction time must be applied for complete H<sub>2</sub> storage. Experiments with repeated hydrogenation-dehydrogenation cycles reveal that reversible H<sub>2</sub> storage and release are possible without degradation of the MBP/H<sub>12</sub> -MBP pair. The prepared MBP satisfies the requirements for chemical stability, handling properties, and cytotoxicity testing.
Human gastrointestinal absorption of acyclovir from tablet duodenal infusion and sipped solution. (1986)

On two occasions at least 1 week apart, nine healthy male volunteers were administered in random order either 2 X 200 mg (1.8 mmol) acyclovir tablets or 400 mg of acyclovir in 500 ml of 5% dextrose solution which was infused at constant rate into the duodenum over 4 h. Six of the subjects subsequently sipped the same solution at the rate of 10.4 ml in each 5 min period for 4 h. Blood and urine were sampled over 24 h for each mode of administration. Acyclovir was assayed by radioimmunoassay. Mean areas under the plasma concentration-time curves (AUCs) +/- s.d. for tablet (T), intraduodenal infusion (I) and sipping (S) were, respectively: T = 14.7 +/- 5.1; I = 24.6 +/- 5.1; S = 28.4 +/- 9.5 (n = 6) mumol l-1 h. AUCs for I and S were significantly greater than that for T (2P less than 0.05). Mean apparent maximum plasma concentrations (Cmax) +/- s.d. were T = 3.8 +/- 1.5; I = 4.8 +/- 0.9; S = 5.1 +/- 1.5 mumol l-1. This trend to higher values for I and S was not significant. Mean apparent plasma disappearance half-lives (t1/2) +/- s.d. were respectively T = 2.3 +/- 0.4; I = 2.7 +/- 0.5; S = 3.0 +/- 0.2 h, I being significantly greater than T (2P less than 0.05), as was S greater than T (2P less than 0.01).(ABSTRACT TRUNCATED AT 250 WORDS)
Omega-aminoalkyl agaroses in the resolution of enzymes involved in regulation of glutamine metabolism. (1975)

Systematic examination of a homologous series of omega-aminoalkyl agaroses showed that the pentyl derivative (Seph-C5-NH2) was best suited for the retention and subsequent separation of several proteins involved in the regulation of glutamine metabolism in Escherichia coli, including: glutamine synthetase [EC 6.3.1.2; L-glutamate:ammonia ligase (ADP-forming)], ATP:glutamine synthetase adenylyltransferase (EC 2.7.7.42), the PII regulatory protein which regulates the adenylylation and deadenylylation activities of the adenylyltransferase, the UTP:PII protein uridylyltransferase, and the uridylyl removing enzyme which catalyzes the removal of uridylyl groups from uridylylated PII protein. Resolution of these proteins was achieved by gradually increasing the concentration of KCl in the eluant, which resulted in consecutive detachment of the proteins from the column. Proteins that co-elute from a DEAE-cellulose column can be resolved and further purified on epsilon-aminopentyl agarose, probably due to the fact that with the homologous series it is possible to adjust the contribution of hydrophobic interactions for optimal resolution.
Hypertension in End-Stage Renal Disease (1969)

Two distinct patterns of response of blood pressure to achievement of dry weight (no clinical evidence of edema and optimal body sodium content and volume of water), antihypertensive drugs and bilateral nephrectomy were documented in 40 unselected patients with end-stage renal disease. Group 1, 35 of 40 patients, was characterized by an excellent response of blood pressure to dry weight and the ability to remain normotensive without antihypertensive drugs as long as dry weight was maintained. Group 2, five of 40 patients, had persistent hypertension in spite of dry weight, a poor response to antihypertensive drugs and a prompt reduction of blood pressure after bilateral nephrectomy. A further important difference between these two groups was seen in the serum renin values obtained at the initiation of therapy. In Group 1 values ranged from 0 to 1.02 Goldblatt units × 10–4 per milliliter of serum (mean, 0.31) whereas those in Group 2 ranged from 1.88 to 4.60 (mean of 3.37 units). Serum renin levels appear to be of value to predict blood-pressure response.

Plan-based Object Search and Exploration using Semantic Spatial Knowledge in the Real World. (2011)

Abstract — In this paper we present a principled planner based approach to the active visual object search problem in unknown environments. We make use of a hierarchical planner that combines the strength of decision theory and heuristics. Furthermore, our object search approach leverages on the conceptual spatial knowledge in the form of object cooccurences and semantic place categorisation. A hierarchical model for representing object locations is presented with which the planner is able to perform indirect search. Finally we present real world experiments to show the feasibility of the approach.
Toxicity Testing in the 21st Century: A Vision and a Strategy (2010)

With the release of the landmark report Toxicity Testing in the 21st Century: A Vision and a Strategy, the U.S. National Academy of Sciences, in 2007, precipitated a major change in the way toxicity testing is conducted. It envisions increased efficiency in toxicity testing and decreased animal usage by transitioning from current expensive and lengthy in vivo testing with qualitative endpoints to in vitro toxicity pathway assays on human cells or cell lines using robotic high-throughput screening with mechanistic quantitative parameters. Risk assessment in the exposed human population would focus on avoiding significant perturbations in these toxicity pathways. Computational systems biology models would be implemented to determine the dose-response models of perturbations of pathway function. Extrapolation of in vitro results to in vivo human blood and tissue concentrations would be based on pharmacokinetic models for the given exposure condition. This practice would enhance human relevance of test results, and would cover several test agents, compared to traditional toxicological testing strategies. As all the tools that are necessary to implement the vision are currently available or in an advanced stage of development, the key prerequisites to achieving this paradigm shift are a commitment to change in the scientific community, which could be facilitated by a broad discussion of the vision, and obtaining necessary resources to enhance current knowledge of pathway perturbations and pathway assays in humans and to implement computational systems biology models. Implementation of these strategies would result in a new toxicity testing paradigm firmly based on human biology.
Level Sets of Viscosity Solutions: some Applications to Fronts and Rendez-vous Problems (1994)

The authors treat some applications of Hamilton–Jacobi equations to the study of a flame front propagation model and the rendez-vows problem. The solution of both problems requires the determination of the level sets of the viscosity solution for the corresponding equation. In the flame front propagation model described here, it is assumed that the evolution is driven by a vector field satisfying a transversality condition at time $t = 0$. The evolution in the normal direction with variable velocity $c( x ) \geq 0$ is considered as a special case. This approach is constructive, permitting the numerical solution of such problems.
GPU rendering for autostereoscopic displays (2008)

In recent years, stereoscopic technology has advanced from stereoscopic to autostereoscopic displays. These latter family involves to display several views of a scene. In the case of real-time computer graphics images, the standard approach consists in rendering every view independently. This paper presents an alternative method to generate multiple views for autostereoscopic displays in a single rendering pass. Our algorithm is based on the fact that vertices properties remain the same from different viewpoints. Taking advantage of the latest generation of GPUs including geometry shaders, we propose a method that significantly speeds up the rendering process by duplicating and transforming incoming primitives for a defined set of views. Our method involves very few modifications to be used with a standard stereo device. 1.
Rearing Two Subterranean Termites, Reticulitermes flavipes and Coptotermes formosanus, on Artificial Diets1 (1975)

Reticulitermes flavipes (Kollar) and Coptotermes formosanus Shiraki termites survived, maintained their weight, and reproduced as well on several artificial diets as they did on a wood block control. The best diet for R. flavipes, and possibly for C. formosanus, included alpha-cellulose (34.06%), water (65.87%), a sterol (0.06%), and methyl-p-hydroxybenzoate (0.01%). Casein or albumen (0.05%) may be added, but their value is questionable, and at levels of 0.5% or greater both proteins were toxic to the termites. Both Î²-sitosterol and ergosterol gave better results than cholesterol. This diet is suitable for physiological or nutritional studies and may be satisfactory for maintaining laboratory colonies of termites.

Design and failure analysis of logic-compatible multilevel gain-cell-based dram for fault-tolerant VLSI systems (2011)

This paper considers the problem of increasing the storage density in fault-tolerant VLSI systems which require only limited data retention times. To this end, the concept of storing many bits per memory cell is applied to area-efficient and fully logic-compatible gain-cell-based dynamic memories. A memory macro in 90-nm CMOS technology including multilevel write and read circuits is proposed and analyzed with respect to its read failure probability due to within-die process variations by means of Monte Carlo simulations.
Electrochemical printing: mass transfer effects (2007)

Electrochemical printing (EcP) is a maskless solid freeform microfabrication process capable of depositing metal and alloy patterns on macroscopically large conductive substrates. The maximum plating rate achievable with EcP is dictated by the mass transfer limiting current density (ilim). The dependence of ilim on the dimensionless fly-height (h/d), the nozzle Reynolds number (Re) and the Schmidt number (Sc) is well known for classical impinging jet systems that employ a well-supported electrolyte and electrodes of similar size to the impinging jet nozzle. Significant ion migration and a large cathode (relative to the nozzle) make EcP mass transfer unique when compared to a classical impinging jet electrode. In this paper, we report experimentally measured limiting currents between 2 and 25 A cm−2. The corresponding simulated limiting currents fall between 1 and 20 A cm−2, for 14 < Re < 290, 0.28 < h/d < 0.7 and Sc = 5507. Best fits of experiments and simulations show the limiting current depends on Re0.31±0.03 for experiments and on Re0.48±0.01 for simulations; both fall in the expected range of Re1/3 and Re1/2 for Sc 1. The fly-height dependence, however, is significantly stronger than a classical impinging jet electrode due to the role of ionic migration and the unique geometry. This work provides useful engineering tools to help implement EcP.
Continuous-Mode Thermal Oxidation of Fischer−Tropsch Waxes (2003)

Selective air oxidation is used on a commercial scale to functionalize paraffinic waxes. Continuous-mode wax oxidation was investigated in an effort to address some of the shortcomings of commercial batch mode operation, as well as to explore ways to improve wax oxidation selectivity. Selectivity trends and probable reaction pathways could be established. It is also shown that continuous-mode wax oxidation is more efficient and differentiates itself from batch-mode wax oxidation by the ability to achieve high selectivity (>85%) to alcohols and ketones and to suppress acid formation completely.
Weight Management in Type 2 Diabetes: Current and Emerging Approaches to Treatment (2015)

Diabetes is a growing global health concern, as is obesity. Diabetes and obesity are intrinsically linked: obesity increases the risk of diabetes and also contributes to disease progression and cardiovascular disease. Although the benefits of weight loss in the prevention of diabetes and as a critical component of managing the condition are well established, weight reduction remains challenging for individuals with type 2 diabetes due to a host of metabolic and psychological factors. For many patients, lifestyle intervention is not enough to achieve weight loss, and alternative options, such as pharmacotherapy, need to be considered. However, many traditional glucose-lowering medications may lead to weight gain. This article focuses on the potential of currently available pharmacological strategies and on emerging approaches in development to support the glycemic and weight-loss goals of individuals with type 2 diabetes. Two pharmacotherapy types are considered: those developed primarily for blood glucose control that have a favorable effect on body weight and those developed primarily to induce weight loss that have a favorable effect on blood glucose control. Finally, the potential of combination therapies for the management of obese patients with type 2 diabetes is discussed.

Gridifying a Diffusion Tensor Imaging Analysis Pipeline (2010)

Diffusion Tensor MRI (DTI) is a rather recent image acquisition modality that can help identify disease processes in nerve bundles in the brain. Due to the large and complex nature of such data, its analysis requires new and sophisticated pipelines that are more efficiently executed within a grid environment. We present our progress over the past four years in the development and porting of the DTI analysis pipeline to grids. Starting with simple jobs submitted from the command-line, we moved towards a workflow-based implementation and finally into a web service that can be accessed via web browsers by end-users. The analysis algorithms evolved from basic to state-of-the-art, currently enabling the automatic calculation of a population-specific `atlas' where even complex brain regions are described in an anatomically correct way. Performance statistics show a clear improvement over the years, representing a mutual benefit from both a technology push and application pull.
Integration of signaling pathways regulating chondrocyte differentiation during endochondral bone formation (2007)

During endochondral bone formation, chondrocytes undergo a process of terminal differentiation or maturation, during which the rate of proliferation decreases, cells become hypertrophic, and the extracellular matrix is altered by production of a unique protein, collagen X, as well as proteins that promote mineralization. The matrix surrounding the hypertrophic chondrocytes eventually becomes mineralized, and the mineralized matrix serves as a template for bone deposition. This process is responsible for most longitudinal bone growth, both during embryonic development and in the postnatal long bone growth plates. Chondrocyte maturation must be precisely controlled, balancing proliferation with terminal differentiation; changes in the rate of either proliferation or differentiation result in shortened bones. Numerous signaling molecules have been implicated in regulation of this process. These include the negative regulators Indian hedgehog (Ihh) and parathyroid hormone-related protein (PTHrP; Pthlh, PTH-like hormone), as well as a number of positive regulators. This review will focus on several positive regulators which exert profound effects on chondrocyte maturation: the thyroid hormones T3 and T4, retinoic acid (the major active metabolite of vitamin A) and bone morphogenetic proteins (BMPs), as well as the transcription factor Runx2. Each of these molecules is essential for endochondral bone formation and cannot compensate for the others; abrogation of any one of them prevents differentiation. The important features of each of these signaling pathways will be discussed as they relate to chondrocyte maturation, and a model will be proposed suggesting how these pathways may converge to regulate this process.
Comparison of a Frequency-based Analysis of Electroencephalograms (Z-ratio) and Visual Scoring on the Multiple Sleep Latency Test (1995)

In a sample of multiple sleep latency test naps following nocturnal polysomnograms from a group of 13 patients of varying ages and diagnoses, we compared a computer-derived electroencephalographic (EEG) measure (z-ratio) with standard visual sleep stage scoring. In this clinical population, z-ratio scoring agreed with human scorers approximately 80% of the time when determining sleep versus wake in 30-second epochs. These results show that a single, objectively quantifiable value derived from a single channel of EEG can distinguish between sleep and wakefulness (as defined by Rechtschaffen and Kales) with at least a moderate degree of precision. When refined, the z-ratio method might be of use as the basis for a new sleep scoring system, particularly where an accurate determination of sleep onset is required.
A Practical Hybrid Digital-Analog Scheme for Wireless Video Transmission (2017)

We propose a hybrid digital-analog framework for wireless video transmission, which benefits from both the high distortion-power performance of digital systems and the graceful performance degradation of analog systems. The proposed framework models video frames as a parallel Gaussian source, which is separated into digital and analog parts through scalar quantization. It features entropy coding and channel coding in digital transmission and power scaling in analog transmission. The key challenge in this framework is how to allocate the constrained power and bandwidth resources between and among digital and analog components to achieve minimal distortion at the receiver. Given the worst-case channel signal-to-noise ratio, we are able to derive a closed-form expression of the overall distortion. However, minimizing it is a mixed-integer non-linear programming problem, which is generally non-deterministic polynomial-time hard. By making reasonable and justified simplifications, we approach the optimal solution through a practical scheme. Evaluations show that the proposed scheme outperforms the state-of-the-art analog scheme SoftCast by a large margin. The gain in received video peak signal-to-noise ratio is up to 5.0 dB for various types of videos.
A method based on Multi-Convolution layers Joint and Generative Adversarial Networks for Vehicle Detection (2019)

In order to achieve rapid and accurate detection of vehicle objects in complex traffic conditions, we propose a novel vehicle detection method. Firstly, more contextual and small-object vehicle information can be obtained by our Joint Feature Network (JFN). Secondly, our Evolved Region Proposal Network (EPRN) generates initial anchor boxes by adding an improved version of the region proposal network in this network, and at the same time filters out a large number of false vehicle boxes by soft-Non Maximum Suppression (NMS). Then, our Mask Network (MaskN) generates an example that includes the vehicle occlusion, the generator and discriminator can learn from each other in order to further improve the vehicle object detection capability. Finally, these candidate vehicle detection boxes are optimized to obtain the final vehicle detection boxes by the Fine-Tuning Network(FTN). Through the evaluation experiment on the DETRAC benchmark dataset, we find that in terms of mAP, our method exceeds Faster-RCNN by 11.15%, YOLO by 11.88%, and EB by 1.64%. Besides, our algorithm also has achieved top2 comaring with MS-CNN, RefineNet, RetinaNet, of vehicle category in KITTI dataset.
