Stabilizing bit-rates in quantized event triggered control systems (2012)

Event triggered systems are feedback systems that sample the state when the novelty in that state exceeds a threshold. Prior work has demonstrated that event-triggered feedback may have inter-sampling intervals that are, on average, greater than the sampling periods found in comparably performing periodic sampled data systems. This fact has been used to justify the claim that event-triggered systems are more efficient in their use of communication or computational resources than periodic sampled data systems. If, however, one accounts for quantization effects and maximum acceptable delays, then it is quite possible that the actual bit-rates generated by event triggered systems may be greater than that of periodically triggered systems. This paper examines the bit-rates required to asymptotically stabilize nonlinear event triggered systems. An increasing upper bound on the stabilizing bit-rate with respect to the norm of the state is derived. This increasing upper bound on the stabilizing bit-rate reveals the efficient attentiveness property of event triggered systems, i.e. the farther the state is away from the origin, the higher the stabilizing bit-rate will be. Moreover, this paper presents the conditions under which the stabilizing bit-rates asymptotically go to 0.
Stroke Incidence, Case Fatality, and Mortality in the WHO MONICA Project (1995)

The WHO MONICA Project provides a unique opportunity to perform cross-sectional and longitudinal comparisons of stroke epidemiology in many populations. The present data show how large differences in stroke incidence and case-fatality rates contribute to the more than threefold differences in stroke mortality rates among populations.
Frequency-domain optical image reconstruction in turbid media: an experimental study of single-target detectability (1997)

An experimental study of the detectability of an object embedded in optically tissue-equivalent media by frequency-domain image reconstruction is presented. The experiments were performed in an 86-mm-diameter cylindrical phantom containing an optically homogeneous cylindrical target whose absorption and scattering properties presented a 2:1 contrast with the background medium. The parameter space explored during experimentation involved object size (15-, 8-, and 4-mm targets) and location (centered, 20-mm off-centered, and 35-mm off-centered) variations. Image reconstruction was achieved with a previously reported regularized least-squares approach that incorporates finite-element solutions of the diffusion equation and Newton's method solutions of the nonlinear minimization problem. Also included during image formation were image enhancement schemes-(1) total variation minimization, (2) dual meshing, and (3) spatial low-pass filtering-which have recently been added. Quantitative measures of image quality including the size, location, and shape of the heterogeneity along with errors in its recovered optical property values are used to quantify the image reconstructions. The results show that a near 22:1 ratio of tissue thickness relative to detectable object size has been achieved with this approach in the laboratory conditions and parameter space that have been investigated.
A Speech Prosthesis Employing a Speech Synthesizer-Vowel Discrimination from Perioral Muscle Activities and Vowel Production (1985)

A speech prosthesis has been developed based on the following idea. When a handicapped person such as a laryngectomee tries to speak in vain, the movements of the mouth, tongue, etc., are elicited. By detecting the movements, what he or she is trying to say can be determined. Then a speech synthesizer is driven to produce a voice of good quality.
QUANTITATIVE COMPARISON OF SUBSTANCES RELATED TO OXYTOCIN: A NEW TEST (1958)

A quantitative method of biological standardisation can be regarded as satisfactory when it is simple, rapid and accurate (Burn et al., 1950). It may be of secondary importance whether a) the function studied is the same as that influenced by the drug in man, and b) the conditions of the experiment are »physiological«. For instance, both the United States Pharmacopoeia (1955) and the British Pharmacopoeia (1953) recommend a method for standardising the oxytocic hormone of pituitary (posterior lobe) preparations which is based on the depression of the blood pressure in a chicken (Coon, 1939) although in clinical practice only the action on uterine muscle is important. In another widely employed method for the standardisation of oxytocin which is also recommended in the British Pharmacopoeia, the contractions of the isolated rat uterus are measured (Holton, 1948) but at a temperature of 32°C. or less, i. e. well below the body temperature.
Doppler navigation (1958)

This paper describes a self-contained radio navigation aid for aircraft which works by virtue of the Doppler principle. Ground speed and drift angle are determined by measuring the Doppler shifts that occur when signals transmitted from a moving aircraft are reflected back from the ground along two or more beams. Ground speed with an error of less than 0.2% and drift angle with an error of less than 0.2° can be obtained with suitable equipment.Drift angle is combined with heading from the aircraft compass to give direction of travel with respect to north, and this information together with ground speed is fed to a unit which computes the aircraft's present position. In general it is found that the accuracy of the indicated position is limited by the accuracy of the aircraft compass.Descriptions are given of the various units of the system, including an aerial which simplifies the problem of obtaining adequate accuracy. The errors are analysed and experimental results are given of those that occur over sea.An account is given of the experimental equipment that was built and tested at the Royal Radar Establishment and which formed the basis of equipments now in production.
New Materials for SLS: The Use of Antistatic and Flow Agents (2016)

Selective laser sintering (SLS) is a process based on the principle of a locally confined energy input by a laser into a powder bed, producing highly complex parts without the use of moulds or any other tools. In order to ensure good results for the processing behaviour of a new material, the powder must perform well during the phase of feeding the material into the process chamber which majorly influences the quality of the spread of the powder into the part bed and thus the mechanical performance of the final parts. In the present study, the principle of modification of fine powders with flow agents is applied aiming to enable the use of powders for SLS which are otherwise unsuitable due to poor flowability. In addition, the influence of antistatic agent on the powder flow and processing behaviour is discussed. The additives are found to strongly improve the flow behaviour at already very small contents and thus allow for processing of the composite material. The development of determining factors shares insight into the mechanisms of dry particle coating and its implementation into a growing market of material development.

Bayesian Generative Active Deep Learning (2019)

Deep learning models have demonstrated outstanding performance in several problems, but their training process tends to require immense amounts of computational and human resources for training and labeling, constraining the types of problems that can be tackled. Therefore, the design of effective training methods that require small labeled training sets is an important research direction that will allow a more effective use of resources.Among current approaches designed to address this issue, two are particularly interesting: data augmentation and active learning. Data augmentation achieves this goal by artificially generating new training points, while active learning relies on the selection of the "most informative" subset of unlabeled training samples to be labelled by an oracle. Although successful in practice, data augmentation can waste computational resources because it indiscriminately generates samples that are not guaranteed to be informative, and active learning selects a small subset of informative samples (from a large un-annotated set) that may be insufficient for the training process. In this paper, we propose a Bayesian generative active deep learning approach that combines active learning with data augmentation -- we provide theoretical and empirical evidence (MNIST, CIFAR-$\{10,100\}$, and SVHN) that our approach has more efficient training and better classification results than data augmentation and active learning.
Is there an alternative to TIPS? Ultrasound-guided direct intrahepatic portosystemic shunt placement in Budd-Chiari syndrome (2010)

Budd-Chiari syndrome is a spectrum of manifestations which develops as a result of hepatic venous outflow obstruction. Transjugular intrahepatic portosystemic shunt (TIPS) is a minimally invasive vascular and interventional radiological procedure indicated in the management of refractory ascites in such patients. Conventional TIPS requires the presence of a patent hepatic vein and reasonable accessibility to the portal vein, and in patients with totally occluded hepatic veins, this procedure is technically challenging. Direct intrahepatic portosystemic shunt (DIPS) or so called "percutaneous TIPS" involves ultrasound-guided percutaneous simultaneous puncture of the portal vein and inferior vena cava followed by introduction of a guidewire through the portal vein into the inferior vena cava, as a deviation from conventional TIPS. Described here is our experience with DIPS. Three patients with BCS who had refractory ascites but were unsuitable for conventional TIPS due to occlusion of the hepatic veins were chosen to undergo the DIPS procedure. Our technical success was 100%. The shunts placed in two patients remain patent to date, while the shunt in a third patient with underlying antiphospholipid syndrome was occluded a month after the procedure. The percutaneous TIPS procedure seems to be technically feasible and effective in the management of refractory ascites as a result of BCS, particularly in the setting of occluded hepatic veins.
<i>KIF13B-NRG1</i> Gene Fusion and <i>KRAS</i> Amplification in a Case of Natural Progression of Lung Cancer (2017)

An 85-year-old woman with a history of several primary lung cancers presented with liver metastases. The primary lung cancers were all managed surgically and the patient did not receive adjuvant or neoadjuvant therapy prior to presenting with metastases. Comparison of molecular testing results from the most recent primary and the liver metastases demonstrated ( a) a clonal relationship between the 2 cancers and ( 2) the presence of a KIF13B-NRG1 fusion and KRAS amplification unique to the metastases. When integrated, the molecular surgical pathology findings in this case illustrate the extent of "oncogenic drive" in preterminal lung cancer.

Bacterial pathways for degradation of nitroaromatics (2006)

The last one hundred years have seen a massive expansion in the chemicals industry; however, with this progress came the concomitant pollution of the environment with a significant range of xenobiotics.Nitroaromatic compounds form one such category of novel environmental contaminants and are produced through a large number of industrial processes, most notably the pesticides, dyes and explosives industries. Whilst singly nitrated aromatic compounds are usually mineralised in the environment, multiply nitrated aromatics, such as the explosive 2,4,6-trinitrotoluene (TNT), are recalcitrant and highly toxic. The predominant route of biological transformation of aromatic compounds is oxidation; however, the presence of three electron-withdrawing nitro-groups around the ring prevents oxidation, rendering such compounds resistant to biodegradation. The subsequent accumulation of these contaminants has stimulated much research leading to the isolation of bacteria that possess, to varying extents, the ability to remediate explosives and other nitroaromatic pollutants.The extreme environments created by these toxic substances accelerate the evolutionary process and examples of bacteria that have conscripted metabolic enzymes for novel remediatory pathways are included. This Highlight ends with a discussion of the future of nitroaromatic bioremediation including engineering plants to express bacterial enzymes for use in bioremediation programs.
Subcellular distribution, synthesis, and release of carcinoembryonic antigen in cultured human colon adenocarcinoma cell lines. (1983)

The content of carcinoembryonic antigen (CEA) and its subcellular distribution were studied in nine human colon carcinoma cell lines. A great variation in CEA content was found among different colon cancer cell lines. Well-differentiated colon cancer cell lines (LS174T and SKCO-1) contained the highest CEA activity which was 35 to 60 times greater than that of less well-differentiated cells (SW620, SW480, and HRT18). More than 80% of the CEA was associated with the cell membrane in all nine cell lines. With increasing cell density, the CEA content per cell was found to increase in SW1116, HCT8, and HCT48 cells, while no change was observed in SW620, HRT18, and HT29 cells. In SW480, LS174T, and SKCO-1 cells, CEA content actually decreased with increasing cell density. Investigation of the synthesis of CEA in cells and its release into the medium over an 8-day period showed that the rate of CEA synthesis at maximum cell density for LS174T and SKCO-1 cells decreased to 15 and 50% of that at low cell density, respectively. In contrast, the rate of CEA release into medium by these two cell lines was higher at maximum than at low cell density. For HCT48 cells, the increased rate of CEA synthesis with increasing cell density markedly elevated cellular CEA levels. These observations were confirmed by studying the rate of incorporation of N-acetyl[3H]-glucosamine into cellular CEA in LS174T and HCT48 cell lines. The rate of incorporation of radioactivity into CEA was greater during the exponential phase of growth than during the stationary phase for LS174T, while the opposite was observed with HCT48 cells. This study indicated that there is a great variation in CEA content among different human colon cancer cell lines and that it is associated predominantly with the membrane fraction. The rate of synthesis and release of CEA also varied among different cell lines. The growth phase had a varied effect on the CEA content, the rate of synthesis, and the release of CEA in these human colon cancer cell lines.
Biological Characteristics and Biomedical Applications of the Squid <i>Sepioteuthis lessoniana</i> Cultured Through Multiple Generations (1994)

Providing squids--especially their giant axons--for biomedical research has now been achieved in 10 mariculture trials extending through multiple generations. The noteworthy biological characteristics of Sepioteuthis lessoniana are (1) this species is behaviorally and morphologically well suited to the laboratory environment; (2) the life cycle is completed in 4-6 months; (3) growth is rapid (12% and 5% wet body weight d-1 for 100 d and for the life span, respectively), with adult size ranging from 0.4-2.2 kg; (4) feeding rates are high (30% wet body weight d-1), and a variety of live crustaceans and fishes are eaten; (5) crowding is tolerated (about 4 squids m-3); (6) the incidence of disease and cannibalism is low; and (7) reproduction in captivity allows culture through three successive generations. Engineering factors contributed to culture success: (1) physical design (i.e., size, shape, and painted pattern) of the culture tanks; (2) patterns of water flow in the culture tanks; (3) water filtration systems; and (4) spawning substrates. Initial production (a few hundred squids per year) suggests that large-scale culture will be able to supply the needs of the biomedical research community. The size (> 400 microns in diameter) and characteristics of the giant axons of Sepioteuthis are appropriate for experimentation, and other studies indicate that the eye, oculomotor/equilibrium system, olfactory system, blood, and ink are equally suitable for research.
