Position control of shape memory alloy actuators with internal electrical resistance feedback using neural networks (2004)

The development of a position control system for a shape memory alloy (SMA) wire actuator using an electrical resistance feedback is presented in this paper. A novel control scheme is implemented to eliminate the need for a position sensor to achieve stable and accurate positioning by utilizing the actuator's electrical resistance feedback. Experiments are conducted to investigate the relationship between electrical resistance and displacement using an SMA wire test set-up. Due to the highly nonlinear behavior of the SMA actuator, a neural network is employed to model the relationship and to predict the position of the actuator using only the electrical resistance. Feedback control of the SMA is achieved by using a proportional-derivative (PD) controller. Experimental results demonstrate that the proposed position control system achieves good control performance without using a position sensor.
LK6, a short lived protein kinase in <i>Drosophila</i> that can associate with microtubules and centrosomes (1997)

A number of polyclonal mouse sera were raised against Drosophila proteins that bound to microtubules in vitro (Kellogg et al. (1989) J. Cell Biol. 109, 2977-2991). Some of these sera recognised centrosomes in vivo, and we have been using these to screen expression libraries to isolate cDNAs encoding these putative centrosomal microtubule-associated proteins. Here we report the cloning of one such cDNA that encodes a novel serine/threonine protein kinase called LK6. The protein appears to exist in two forms: an abundant 185 kDa form and a rarer approximately 220 kDa form that interacts with microtubules. At least some of the LK6 protein is located in centrosomes at all stages of the cell cycle in fly embryos. Interestingly, the protein contains a PEST-like sequence and is rapidly turned over in vivo. Constitutive overexpression of LK6 is deleterious to flies and causes defects in microtubule organisation in both eggs and early embryos, whereas constitutive overexpression of a mutant form containing a point mutation that severely impairs the kinase activity is without effect. These findings suggest that LK6 may play a role in regulating microtubule function.
Advanced virtualization capabilities of POWER5 systems (2005)

IBM POWER5™ systems combine enhancements in the IBM PowerPC™ processor architecture with greatly enhanced firmware to significantly increase the virtualization capabilities of IBM POWER™ servers. The POWER hypervisor, the basis of the IBM Virtualization Engine™ technologies on POWER5 systems, delivers leading-edge mainframe virtualization technologies to the UNIX® marketplace. In addition to being able to create computing-intensive partitions with dedicated resources (processors, memory, and I/O adapters), customers can harness idle processor capacity to configure micropartitions with virtualized resources in order to consolidate many AIX™, i5/OS™, and Linux® servers onto a single platform. The POWER hypervisor provides support for virtualized processors, an IEEE virtual local area network (VLAN)-compatible virtual Ethernet switch, virtual small computer system interface (VSCSI) adapters, and virtual consoles. Many of these features are dependent upon, or take advantage of, the new facilities provided in the POWER5 processor, including the hypervisor decrementer, a fast page mover, and simultaneous multithreading support. The technology behind the virtualization capabilities that are available on the POWER5 servers, enabling customers to better utilize the industry-leading computing capacity of the POWER5 processor, is discussed in this paper.
Synthesis of 5-Substituted Quinolin-8-ols (1997)

A new preparative procedure for 5-aryl- or 5-decylquinolin-8-ols was developed. The key step of the procedure is the cross coupling of 8-benzyloxy-5-bromoquinoline with arylboronic acid or 9-decyl-9-borabicyclo[3.3.1]nonane (Suzuki reaction). Deprotection of the benzyloxy group was accomplished successfully by Pd/C catalyzed hydrogen transfer from cyclohexa-1,4-diene.
<i>Actinomyces europaeus</i>Isolated from a Breast Abscess in a Penicillin-Allergic Patient (2018)

This is a case of <i>Actinomyces europaeus</i> in the breast abscess of a penicillin-allergic woman. The mainstay of treatment for actinomycosis is penicillin, and there is a lack of literature describing nonpenicillin treatment options. A 69-year-old woman presented acutely with a breast abscess which was managed with incision and drainage and antibiotic therapy to good response. 21 days after presentation, <i>Actinomyces</i> were grown from the culture of pus, so the patient was recalled and more rigorous treatment and follow-up were initiated. The penicillin allergy led to difficulty in the identification of an appropriate antimicrobial agent that was also logistically feasible to be given on an outpatient IV basis. IV tigecycline followed by oral clarithromycin was found to be effective treatment.
The Impact of a Consortium of Fermented Milk Strains on the Gut Microbiome of Gnotobiotic Mice and Monozygotic Twins (2011)

Understanding how the human gut microbiota and host are affected by probiotic bacterial strains requires carefully controlled studies in humans and in mouse models of the gut ecosystem where potentially confounding variables that are difficult to control in humans can be constrained. Therefore, we characterized the fecal microbiomes and metatranscriptomes of adult female monozygotic twin pairs through repeated sampling 4 weeks before, 7 weeks during, and 4 weeks after consumption of a commercially available fermented milk product (FMP) containing a consortium of Bifidobacterium animalis subsp. lactis, two strains of Lactobacillus delbrueckii subsp. bulgaricus, Lactococcus lactis subsp. cremoris, and Streptococcus thermophilus. In addition, gnotobiotic mice harboring a 15-species model human gut microbiota whose genomes contain 58,399 known or predicted protein-coding genes were studied before and after gavage with all five sequenced FMP strains. No significant changes in bacterial species composition or in the proportional representation of genes encoding known enzymes were observed in the feces of humans consuming the FMP. Only minimal changes in microbiota configuration were noted in mice after single or repeated gavage with the FMP consortium. However, RNA-Seq analysis of fecal samples and follow-up mass spectrometry of urinary metabolites disclosed that introducing the FMP strains into mice results in significant changes in expression of microbiome-encoded enzymes involved in numerous metabolic pathways, most prominently those related to carbohydrate metabolism. B. animalis subsp. lactis, the dominant persistent member of the FMP consortium in gnotobiotic mice, up-regulates a locus in vivo that is involved in the catabolism of xylooligosaccharides, a class of glycans widely distributed in fruits, vegetables, and other foods, underscoring the importance of these sugars to this bacterial species. The human fecal metatranscriptome exhibited significant changes, confined to the period of FMP consumption, that mirror changes in gnotobiotic mice, including those related to plant polysaccharide metabolism. These experiments illustrate a translational research pipeline for characterizing the effects of FMPs on the human gut microbiome.
Neural networks for solving systems of linear equations and related problems (1992)

Various circuit architectures of simple neuron-like analog processors are considered for online solving of a system of linear equations with real constant and/or time-variable coefficients. The proposed circuit structures can be used, after slight modifications, in related problems, namely, inversion and pseudo-inversion of matrices and for solving linear and quadratic programming problems. Various ordinary differential equation formulation schemes (generally nonlinear) and corresponding circuit architectures are investigated to find which are best suited for VLSI implementations. Special emphasis is given to ill-conditioned problems. The properties and performance of the proposed circuit structures are investigated by extensive computer simulations.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Evaluation using multilayer perception neural networks: a case study of undulatory median fin swimming in the knifefish <i>Xenomystus nigri</i> (2007)

In this study, artificial intelligence, namely multilayer perception neural networks (MLP‐NN), was employed to predict the hydrodynamic performance of undulatory median fin propulsion in Xenomystus nigri . Good agreement was found between MLP‐NN predictions and actual mean thrust and power values calculated from elongated‐body theory. MLP‐NN has the ability to be a predictive tool for autonomous underwater vehicle design and hydrodynamic performance.
The Putative Response Regulator BaeR Stimulates Multidrug Resistance of <i>Escherichia coli</i> via a Novel Multidrug Exporter System, MdtABC (2002)

Overproduction of the response regulator BaeR confers resistance to novobiocin and bile salts in a DeltaacrAB mutant by stimulating drug exporter gene expression. The mdtABC (multidrug transporter ABC, formerly known as yegMNO) genes, which encode a resistance-nodulation-cell division (RND) drug efflux system, are responsible for resistance. The MdtABC system comprises the transmembrane MdtB/MdtC heteromultimer and MdtA membrane fusion protein. MdtAC also confers bile salt, but not novobiocin, resistance. This indicates that the evolution from an MdtC homomultimer to an MdtBC heteromultimer contributed to extend the drug resistance spectrum. A BLAST search suggested that such a heteromultimer-type RND exporter constitutes a unique family among gram-negative organisms.
3D effect generation from monocular view (2003)

Describes the technique used to generate stereo pair images starting from a single image source (single view-point) and its related depth map. The conjunction between source image and depth map allows reconstruction artificially of the binocular view producing a 3D effect depending on screen dimension and image resolution. The system does not reconstruct the real 3D-coordinates of any object inside the scene, but simply assigns the most comfortable shift to the source points to give a 3D-entertainment to the viewer. A simple smoothing filtering technique adaptively resolves the occlusions generated by shifting of the source points without introducing visible and/or annoying artifacts.
Migraine. Identifying and removing barriers to care. (1994)

The high levels of pain and disability associated with undiagnosed migraine or inadequate treatment of migraine offer a potential target for healthcare intervention. Both the individual patient and society are affected by decisions regarding which migraine sufferers are most in need of medical care. Pain is the most important symptom for the individual patient, but disability may be the most important consequence of migraine for an increasingly cost-conscious society. These two perspectives are the components of a migraine severity or impact measure being developed to define migraine sufferers most in need of care. The criteria for developing screening programs provide a context for evaluating healthcare interventions for migraine. Barriers to effective care occur on at least three levels: many people with migraine do not consult doctors; consulters may not receive the correct diagnosis; and even when the correct diagnosis is made, many migraineurs do not receive effective treatment. Screening and impact measures may help both to improve diagnosis and to determine which migraineurs are most in need of care. Public and physician education, screening, and impact measures might circumvent many of the barriers to effective care for people with migraine.
STUDIES ON GLAUCOMA RELATIVES (1962)

THE purpose of the present study is to find out if thorough screening of a small selected section of the population would be clinically valuable in the early diagnosis of glaucoma simplex. Mass screening of people over 40 years of age would certainly reduce the incidence of blindness due to glau- coma, but screening on such a scale would, for practical reasons, have to be limited to tonometry and optic disc inspection.
Driving style classification using long-term accelerometer information (2014)

Driving style can be characteristically divided into normal and aggressive. Related researches show that useful information about driving style can be extracted using vehicle's inertial measurement signals with the help of GPS. However, for public transportation the GPS sensor isn't necessary because of repetition of the route. This assumption helps to create low-cost intelligent public transport monitoring system that is capable to classify aggressive and normal driver. In this paper, we propose pattern recognition approach to classify driving style into aggressive or normal automatically without expert evaluation and knowledge using accelerometer data when driving the same route in different driving styles. 3-axis accelerometer signal statistical features were used as classifier inputs. The results show that aggressive and normal driving style classification of 100% precision is achieved using collected data when driving the same route.
A 100-MHz 4-Mb cache DRAM with fast copy-back scheme (1992)

A 4-Mb cache dynamic random access memory (CDRAM), which integrates 16-kb SRAM as a cache memory and 4-Mb DRAM into a monolithic circuit, is described. This CDRAM has a 100-MHz operating cache, newly proposed fast copy-back (FCB) scheme that realizes a three times faster miss access time over with the conventional copy-back method, and maximized mapping flexibility. The process technology is a quad-polysilicon double-metal 0.7- mu m CMOS process, which is the same as used in a conventional 4-Mb DRAM. The chip size of 82.9 mm/sup 2/ is only a 7% increase over the conventional 4-Mb DRAM. The simulated system performance indicated better performance than a conventional cache system with eight times the cache capacity.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
High quality 3D laser ranging under general vehicle motion (2008)

This paper describes an end-to-end system capable of generating high-quality 3D point clouds from the popular LMS200 laser on a continuously moving platform. We describe the hardware, data capture, calibration and data stream processing we have developed which yields remarkable detail in the generated point clouds of urban scenes. Given the increasing interest in outdoor 3D navigation and scene reconstruction by mobile platforms, our aim is to provide a level of hardware and algorithmic detail suitable for replication of our system by interested parties who do not wish to invest in dedicated 3D laser rangers.
Forward transient behavior of PiN and super junction diodes (2004)

It is known that the forward transient behavior of the diode has adverse effects like power losses and noise problems on switching power supplies. However, only a few attempts have been made to analyze the forward transient behavior, in contrast to the vigorous research activity in the reverse recovery process. In this study, the forward transient behavior of pin diodes is investigated and the effects of lifetime, doping concentration and thickness of each region of the diode on peak forward recovery voltage and forward recovery time are shown for the first time. Moreover, we demonstrate with simulated and measured results that the super junction diodes have significantly improved forward recovery characteristics.
Real-time angular scatter imaging system for improved tissue contrast in diagnostic ultrasound images (1994)

A new type of real-time ultrasound imaging system has been developed. In contrast to conventional systems, which process only echoes scattered directly back from tissue to form an image, this system images tissue by displaying energy scattered at other angles. In its present form, the system uses one 32 element, 2.4 MHz phased array transducer in transmit and a second, spatially separate 32 element, 2.4 MHz phased array transducer in receive, to detect sound which is scattered away from the transmit transducer. In order to form an image line, the transmit transducer sends into the body a steered pulse, which is tracked dynamically from the side by the receive transducer. The signal detected by the receive transducer is processed in the same manner as in a standard B-mode phased array system. The final display format is a gray scale sector originating from the transmit transducer. Real-time angular scatter images of phantom and in vivo targets have been formed and compared to standard backscatter B-mode images of the same targets.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Task facilitator for special education using MIRA (MIRATaskGen) (2012)

This paper describes a software tool designed for generating a logical sequence of tasks in the task analysis process of special education. The software receives various action related inputs along with the start and finish stages and generates a sequence of tasks from the start to finish. This tool also informs the user, whether the desired goal could be achieved. If the desired goal could not be achieved, then the sequence of actions from the start to a point of discontinuity is detected. The tool is developed using the formalism, namely MIRA (Mimamsa Inspired Representation of Actions), which has the feature of expressing an action as reason, instruction and goal.
Complete Register Allocation Problems (1975)

The search for efficient register allocation algorithms dates back to the time of the first FORTRAN compiler for the IBM 704. The model we use in this paper is a single processor with an arbitrarily large number of general registers. The objective is to use as few registers as possible, under the,constraint that no stores into memory are permitted. The programs under consideration are sequences of assignment instructions. We show that, given a program and an integer k, determining if the program can be computed using k registers is polynomial complete. It should be noted that k can be any integer.
Recent developments in the treatment of acute abdominal and facial attacks of hereditary angioedema: focus on human C1 esterase inhibitor (2010)

Hereditary angioedema (HAE) is a potentially fatal genetic disorder typified by a deficiency (type I) or dysfunction (type II) of the C1-inhibitor (C1-INH) and characterized by swelling of the extremities, face, trunk, abdominal viscera, and upper airway. Type III is normal estrogen-sensitive C1-INH HAE. Bradykinin, the main mediator of HAE, binds to endothelial B2 receptors, increasing vascular permeability and resulting in edema. HAE management includes short- and long-term prophylaxis. For treating acute episodes, C1-INH concentrate is recommended with regression of symptoms achieved in 30-90 min. Infusions of 500-1000 U have been used in Europe for years. Two plasma-derived C1-INH concentrates have been licensed recently in the United States: Berinert(®) for treating acute attacks and Cinryze(®) for prophylaxis in adolescent/adult patients. A recombinant C1-INH that is being considered for approval (conestat alfa) exhibited significant superiority versus placebo. Ecallantide (Kalbitor(®)) is a selective kallikrein inhibitor recently licensed in the United States for treating acute attacks in patients aged >16 years. It is administered in three 10-mg subcutaneous injections with the risk of anaphylactic reactions. Icatibant (Firazyr(®)) is a bradykinin B2 receptor competitor. It is administered subcutaneously as a 30-mg injection and approved in Europe but not in the United States.
Spectral methods for community detection and graph partitioning (2013)

We consider three distinct and well-studied problems concerning network structure: community detection by modularity maximization, community detection by statistical inference, and normalized-cut graph partitioning. Each of these problems can be tackled using spectral algorithms that make use of the eigenvectors of matrix representations of the network. We show that with certain choices of the free parameters appearing in these spectral algorithms the algorithms for all three problems are, in fact, identical, and hence that, at least within the spectral approximations used here, there is no difference between the modularity- and inference-based community detection methods, or between either and graph partitioning.
Balloon angioplasty in congenital heart disease. (1988)

Balloon angioplasty and valvuloplasty offer an alternative to surgery in many congenital cardiac conditions and are a useful adjunct in others. To yield optimal results, the most desirable improvement in hemodynamics with the least amount of damage to normal tissue, choice of the catheter should take into consideration the size of the balloon, type of shaft and shape of the balloon. Experience has shown that dilatation is best achieved when the size of the balloon is such that there is a combination of circumferential force, the stress exerted when the balloon is near its maximal diameter, and longitudinal force, the extent of which is directly proportional to the deformity of the balloon. If the balloon is too small, little benefit may be accrued from the procedure; if it is too large, there is a risk of danger to adjacent normal structures. A stiff shaft helps to maintain a stable position during inflation and the size of the shaft determines the caliber of the guidewire lumen and the inflation/deflation lumen. A single, circular balloon has the advantage of distributing the dilating forces uniformly during inflation; more recently introduced alternative designs with two or three balloons mounted around the shaft have the advantage of allowing some blood flow to occur even at full inflation but they also have the theoretical disadvantage of not ensuring an even distribution of circumferential force. Dilatation of pulmonary valve stenosis may be considered indicated in the presence of a pressure gradient of 40 mm Hg with a right ventricular pressure of 60 mm Hg as the lower limit. In the newborn, this may be qualified by setting the lower limit of right ventricular pressure as 10 mm Hg below systemic arterial pressure if that is 60 mm Hg or less. On choice of the proper balloon size, approximately 20 to 30 percent greater than the pulmonary root, success may be expected in 90% of the cases and, in general, the initial result appears to be that which persists. Although Doppler echocardiography frequently shows pulmonary regurgitation, this is rarely clinically evident. The procedure is safe and only few complications have been reported. Establishing the indication for aortic valvuloplasty usually requires the presence of a systolic gradient of 60 mm Hg without severe regurgitation; mild aortic regurgitation is not a contraindication to the procedure. Reports have indicated good results in both infants and children. This procedure is not without risk and deaths have been reported.(ABSTRACT TRUNCATED AT 400 WORDS)
REAKTIONEN MIT OXYDIERENDEN ENZYMEN AUS MIKROORGANISMEN (1961)

Bei der Zersetzung der Pflanzenrückstände wird das in ihnen vorhandene Lignin durch die Einwirkung von Mikroorganismen verändert. Dabei entstehen unter anderem niedermolekulare Verbindungen vom Typus der Mono–, Dioder Triphenole mit teilweise methylierten OH–Gruppen und einer Seitenkette aus drei Kohlenstoffatomen oder einer Carboxylgruppe.
