An investigation of the ion beam of a plasma focus using a metal obstacle and deuterated target (1991)

The results of an experimental study of the ion beam properties of a 3.3-kJ, 15-kV plasma focus are reported. The plasma focus is operated at 3 torr deuterium, and neutron yield measurements are made with a copper obstacle or deuterated target placed at various axial positions from the end of the anode. It is found that in the normal operation of the focus without an obstacle or target, less than 15% of the neutrons are produced within the pinch column, and that more than 85% of the neutrons arise from the deuterium-ion-beam bombardment of the deuterium gas in the region 20-60 mm from the end of the anode. The neutron production is highest between 30-40 mm from the anode. The results are valid only for a small focus.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Escherichia coli activity characterization using a laser dynamic speckle technique (2012)

The results of applying a laser dynamic speckle technique to characterize bacterial activity are presented. The speckle activity was detected in two-compartment Petri dishes. One compartment was inoculated and the other one was left as a control blank. The speckled images were processed by the recently reported temporal difference method. Three inoculums of 0.3, 0.5, and 0.7 McFarland units of cell concentration were tested; each inoculum was tested twice for a total of six experiments. The dependences on time of the mean activity, the standard deviation of activity and other descriptors of the speckle pattern evolution were calculated for both the inoculated compartment and the blank. In conclusion the proposed dynamic speckle technique allows characterizing the activity of Escherichia coli bacteria in solid medium.
Betting, bribery, and bankruptcy-a simulated economy that learns to predict (2003)

Derby is a collection of independent computational entities that exchange money for work and information in the course of solving some problem. The key to building an agoric system is to design a monetary incentive structure that forces the individual entities to cooperate and work on the user's problem. While building Derby the authors discovered that it is very useful to think of the entities as being opportunistic and uncooperative. In Derby, information is traded in marketplaces, with sellers issuing predictions and placing bets on their correctness at predicting incoming data streams. Buyers submit bids of how much they are willing to pay for each dollar of bet placed. A sealed-bid second-price double auction determines which bidders are accepted. Later, the buyers report how happy they were with the information they bought, and this determines each seller's winnings in the parimutuel betting pool.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Comparison of Three Methods of Eliminating Musical Tones in Speech Denoising Subtractive Techniques (2006)

Speech enhancement techniques, using spectral subtraction, have the drawback of generating an annoying residual noise with musical character. In this paper, we use and compare different post-processing methods of musical tones reduction. All these approaches need both a musical noise detector and a musical noise reducer. For each part, we propose 'non perceptual' and perceptual based approaches. The musical noise detector is based either on shape characteristics or masking consideration. To reduce musical noise, three techniques are used. The first eliminates musical tones in time domain by adding a synthesized signal to the denoised signal. The second operates in the spectral domain and consists in shifting down the detected musical tones under a proposed masking threshold. The third consists in shape modification of detected musical tones. Experiments results show that perceptual based approaches are the best ones.
Percutaneous Decompression of Benign and Malignant Biliary Obstruction (1979)

Percutaneous transhepatic catheterization of the biliary tree was performed in 41 patients with obstructive jaundice. In 39 patients, the catheter was successfully advanced past the obstructing lesion into the distal common duct and duodenum to establish internal biliary drainage. The remaining two patients had the obstructed biliary tract drained externally. Chronic internal catheter drainage was instituted in five patients with stricture and ten with malignant obstruction as a means of palliating symptomatic jaundice. Twenty-two patients had marked reduction in serum bilirubin levels and pruritus, eight patients had moderate decreases in serum bilirubin levels, and six patients did not improve despite adequate catheterization due to hepatic parenchymal disease. This procedure effectively decompresses the severely obstructed biliary tree prior to surgery and can also palliate patients with unresectable malignant biliary obstruction and stent high-risk, benign strictures.
Nonhematopoietic NADPH oxidase regulation of lung eosinophilia and airway hyperresponsiveness in experimentally induced asthma (2007)

Pulmonary eosinophilia is one of the most consistent hallmarks of asthma. Infiltration of eosinophils into the lung in experimental asthma is dependent on the adhesion molecule vascular cell adhesion molecule-1 (VCAM-1) on endothelial cells. Ligation of VCAM-1 activates endothelial cell NADPH oxidase, which is required for VCAM-1-dependent leukocyte migration in vitro. To examine whether endothelial-derived NADPH oxidase modulates eosinophil recruitment in vivo, mice deficient in NADPH oxidase (CYBB mice) were irradiated and received wild-type hematopoietic cells to generate chimeric CYBB mice. In response to ovalbumin (OVA) challenge, the chimeric CYBB mice had increased numbers of eosinophils bound to the endothelium as well as reduced eosinophilia in the lung tissue and bronchoalveolar lavage. This occurred independent of changes in VCAM-1 expression, cytokine/chemokine levels (IL-5, IL-10, IL-13, IFNgamma, or eotaxin), or numbers of T cells, neutrophils, or mononuclear cells in the lavage fluids or lung tissue of OVA-challenged mice. Importantly, the OVA-challenged chimeric CYBB mice had reduced airway hyperresponsiveness (AHR). The AHR in OVA-challenged chimeric CYBB mice was restored by bypassing the endothelium with intratracheal administration of eosinophils. These data suggest that VCAM-1 induction of NADPH oxidase in the endothelium is necessary for the eosinophil recruitment during allergic inflammation. Moreover, these studies provide a basis for targeting VCAM-1-dependent signaling pathways in asthma therapies.
Diffusion-Tensor Imaging Derived Metrics of the Corpus Callosum in Children With Neurofibromatosis Type I (2012)

Children with NF-1 have abnormal DTI metrics, particularly in the genu, and elevated whole-brain mean diffusivity. NF-1-related microstructural abnormalities of the corpus callosum are detectable in childhood and likely persist through myelination maturation.

IBM WebSphere Commerce Suite Product Advisor (2001)

This paper describes the Product Advisor component of the IBM WebSphere™ Commerce Suite. Product Advisor consists of a set of tools to be used by marketing personnel to generate, without programming help, Web shopping applications involving a product catalog. The user interfaces generated by these tools cover an extensible set of shopping paradigms including parametric search, a knowledge-based “virtual salesperson,” and side-by-side comparison shopping. The paper also describes the Java™ infrastructure that supports the Product Advisor tools: servlets, JavaBeans™ and JavaServer Pages™ in the server, and applets in the client. Furthermore, it describes the implementation techniques used for rendering dynamic data: a data container hierarchy, a data type hierarchy, and presentation beans.
Verifiable symmetric searchable encryption for semi-honest-but-curious cloud servers (2012)

Outsourcing data to cloud servers, while increasing service availability and reducing users' burden of managing data, inevitably brings in new concerns such as data privacy, since the server may be honest-but-curious. To mediate the conflicts between data usability and data privacy in such a scenario, research of searchable encryption is of increasing interest. Motivated by the fact that a cloud server, besides its curiosity, may be selfish in order to save its computation and/or download bandwidth, in this paper, we investigate the searchable encryption problem in the presence of a semi-honest-but-curious server, which may execute only a fraction of search operations honestly and return a fraction of search outcome honestly. To fight against this strongest adversary ever, a verifiable SSE (VSSE) scheme is proposed to offer verifiable searchability in additional to the data privacy, both of which are further confirmed by our rigorous security analysis. Besides, we treat the practicality/efficiency as a central requirement of a searchable encryption scheme. To demonstrate the lightweightness of our scheme, we implemented and tested the proposed VSSE on a laptop (serving as the server) and a mobile phone running Android 2.3.4 (serving as the end user). The experimental results optimistically suggest that the proposed scheme satisfies all of our design goals.
A rapid and simple method for inactivating chromosomal genes in<i>Yersinia</i> (2003)

A polymerase chain reaction (PCR)-based procedure without any cloning step was developed for a rapid mutagenesis/deletion of chromosomal target genes in Yersinia. For this purpose, a PCR fragment carrying an antibiotic resistance gene flanked by regions homologous to the target locus is electroporated into a recipient strain expressing the highly proficient homologous recombination system encoded by plasmid pKOBEG-sacB. Two PCR procedures were tested to generate an amplification product formed of an antibiotic resistance gene flanked by short (55 bp) or long (500 bp) homology extensions. Using this method, three chromosomal loci were successfully disrupted in Yersinia pseudotuberculosis. The use of this technique allows rapid and efficient large-scale mutagenesis of Yersinia target chromosomal genes.
Statistical analysis of mutant allele frequency level of circulating cell-free DNA and blood cells in healthy individuals (2017)

Cell-free DNA (cfDNA) in plasma has emerged as a potential important biomarker in clinical diagnostics, particularly in cancer. However, somatic mutations are also commonly found in healthy individuals, which interfere with the effectiveness for cancer diagnostics. This study examined the background somatic mutations in white blood cells (WBC) and cfDNA in healthy controls based on sequencing data from 821 non-cancer individuals and several cancer samples with the aim of understanding the patterns of mutations detected in cfDNA. We determined the mutation allele frequencies in both WBC and cfDNA using a panel of 50 cancer-associated genes that covers 20 K-nucleotide region and ultra-deep sequencing with average depth >40000-fold. Our results showed that most of the mutations in cfDNA were highly correlated to WBC. We also observed that the NPM1 gene was the most frequently mutated gene in both WBC and cfDNA. Our study highlighted the importance of sequencing both cfDNA and WBC to improve the sensitivity and accuracy for calling cancer-related mutations from circulating tumour DNA, and shedded light on developing a strategy for early cancer diagnosis by cfDNA sequencing.
Developing knowledge management metrics for measuring intellectual capital (2000)

Measuring intellectual capital is a growing area of interest in the knowledge management field. Metrics are being developed and applied by some organizations, but there needs to be more research throughout the international community to better define these measures. One limitation of the current measures is that they do not necessarily address the “knowledge level” and the types of value‐added knowledge that individuals obtain. This paper takes a look at the current measures, discusses some possible limitations, and suggests some additional measures that could be used in the intellectual capital area to complement existing measures.
Ultrasound of the shoulder. (2008)

Ultrasound has been widely used for the evaluation of the shoulder, mainly for rotator cuff pathology. Developments in technology, as well as better knowledge of the pathology and the anatomy make this examination one of the most useful in the exploration of the shoulder, especially in the hands of the experienced radiologist. Ultrasound is low-cost, readily available and should be considered with plain films as the first step examination of the shoulder. Ultrasound is not only useful for the evaluation of the rotator cuff pathology and impingement syndrome, but is also performing in the evaluation of non rotator cuff pathology such as biceps tendon pathology, shoulder instability, mass evaluation, infection, degenerative and inflammatory arthropathies and nerve entrapment syndromes. Making a complete evaluation of the shoulder helps to differentiate between rotator cuff pathology and others that can mimic rotator cuff disorders. This article will review shoulder anatomy and examination technique and the different pathologies that can be assessed by ultrasound.
The hirudin-binding site of human α-thrombin (1989)

Chemical modification of 6 lysyl residues within the B-chain of alpha-thrombin was decreased on binding of equal molar hirudin, a thrombin-specific inhibitor. They are Lys-B21 (87% protected), Lys-B52 (80%), Lys-B65 (greater than 95%), Lys-B106 (71%), Lys-B107 (71%), and Lys-B154 (80%). The data suggest that these lysyl residues are situated within or in close proximity to the hirudin-binding site of human alpha-thrombin.
HUMANOID ROBOTS AS COOPERATIVE PARTNERS FOR PEOPLE (2004)

This paper presents an overview of our work towards building socially intelligent, cooperative humanoid robots that can work and learn in partnership with people. People understand each other in social terms, allowing us to engage others in a variety of complex social interactions including communication, social learning, and cooperation. We present our theoretical framework that is a novel combination of Joint Intention Theory and Situated Learning Theory and demonstrate how it can be applied to develop our sociable humanoid robot, Leonardo. We demonstrate the robot’s ability to learn quickly and effectively from natural human instruction using gesture and dialog, and then cooperate to perform a learned task jointly with a person. Such issues must be addressed to enable many new and exciting applications for robots that require them to play a long-term role in people’s daily lives. Keywords: 1.
Interactions of the Extracellular Matrix and Progenitor Cells in Cutaneous Wound Healing (2013)

An efficient and appropriate healing response in the skin postinjury is regulated by a fine balance of the quantity and quality of ECM proteins. A more complete understanding of ECM regulation of the cell fate and activities during cutaneous wound repair is vital for the development of novel treatment strategies for improvement of cutaneous healing.
A 70–90-GHz High-Linearity Multi-Band Quadrature Receiver in ${\hbox{0.35-}}\mu{\hbox {m}}$ SiGe Technology (2013)

An integrated frequency agile quadrature E-band receiver is presented in this paper. The complete receiver is realized in a commercial 0.35-μm SiGe:C technology with an ft/fmax of 170/250 GHz. The receiver covers the two point-to-point communication bands from 71 to 76 GHz and from 81 to 86 GHz and the automotive radar band at 77 GHz. A wide tuning range modified Colpitts oscillator provides a local oscillator (LO) tuning range > 30%. A two-stage constant phase RC polyphase network is implemented to provide wideband in-phase quadrature LO signals. The measured phase imbalance of the network stays below 8 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">°</sup> over the receiver's frequency range. In addition the chip includes a wideband low-noise amplifier, Wilkinson power divider, down conversion mixers, and frequency prescaler. Each of the chip's receiver I/Q paths shows a measured conversion gain above 19 dB and an input referred 1-dB compression point of -22 dBm. The receiver's measured noise figure stays below 11 dB over the complete frequency range. Furthermore, the receiver has a measured IF bandwidth of 6 GHz. The complete chip including prescaler draws a current of 230 mA from a 3.3-V supply, and consumes a chip area of 1628 μm×1528 μm.
Distinct β‐clamp interactions govern the activities of the Y family PolIV DNA polymerase (2009)

The prototypic Y family DNA polymerase IV (PolIV) of Escherichia coli is involved in multiple replication-associated processes including spontaneous mutagenesis, translesion synthesis (TLS), cell fitness, survival under stressful conditions and checkpoint like functions. It interacts physically and functionally with the replisome's beta processivity clamp through the canonical PolIV C-terminal peptide (CTP). A second interaction that involves a portion of the little finger (LF) domain of PolIV has been structurally described. Here we show that the LF-beta interaction stabilizes the clamp-polymerase complex in vitro and is necessary for the access of PolIV to ongoing replication forks in vivo. However, in contrast to the CTP-beta, the LF-beta interaction is dispensable for the role of the polymerase in TLS. This discloses two independent modes of action for PolIV and, in turn, uncovers a novel way by which the cell may regulate the potentially deleterious effect of such low fidelity polymerases during replication.
Improvement of the QoS via an adaptive and dynamic distribution of applications in a mobile environment (2002)

Mobile computing is a domain in great expansion. Wireless networks and Portable Information Appliances (PIAs) are developing very rapidly. More and more mobile users would like to perform their multimedia applications with the same facility as on their desktop station. Use of such applications in a mobile environment raises new challenges. These applications are interactive and extremely costly in system and network resources, whereas PIA resources are poor and wireless networks offer a very variable quality of connection. The authors propose an adaptive and dynamic distribution of applications on the local environment to overcome the poorness of available resources on PIAs, and to reduce and regulate variability effects.

Physiological identification of human transcripts translationally regulated by a specific microRNA (2005)

One mechanism by which endogenous microRNAs (miRNAs) function is to suppress translation of target mRNAs. Computational identification of target mRNAs is hampered by the partial complementarity between miRNAs and their targets and the lack of in vivo approaches to identify targets. Here, we identify mRNAs that are regulated by specific endogenous miRNA by detecting shifts in individual mRNA abundance in polyribosome profiles following miRNA knockdown via siRNA. We have identified human genes whose mRNAs were found at significantly increased levels in the heavy polyribosome fractions following miRNA miR-30a-3p knockdown. If antibody was available, targets showed an increase in protein levels following the miRNA knockdown and a decrease following the miRNA overexpression. Although all identified transcripts have sequences that partially complement miR-30a-3p, none was identified by commonly used computational means. These data suggest that the functional interaction between miRNAs and mRNA targets is more complex than previously realized and describe an approach to refine predictive algorithms.
Heck-Type Arylation of 2-Cycloalken-1-ones with Arylpalladium Intermediates Formed by Decarboxylative Palladation and by Aryl Iodide Insertion (2004)

[reaction: see text] A palladium-catalyzed decarboxylative arylation reaction was shown to produce Heck-type coupling products using a number of different arene carboxylic acid and 2-cycloalken-1-one substrates. The more conventional Heck coupling of an aryl iodide and a 2-cycloalken-1-one reactant was also briefly explored for comparison, where it was found that phosphine-free (Jeffery) conditions afforded the highest yield of product.
