Binary signal design for approximately synchronized CDMA systems without detection sidelobe nor co-channel interference using auto- and cross-complementary codes (2002)

For mobile cellular CDMA systems, co-channel interference in the uplink is the most serious problem, because the power control or the interference cancellation required increase the system's cost. From this view point, Suehiro (1993, 1994) proposed a method for signal design by applying the pseudo-periodic sequences concept on the periodic sequence set without cross-correlation. Using this method, we can design CDMA signals without co-channel interference when the system is approximately synchronized. Approximate synchronization is not difficult for uplink in cellular mobile systems, so this signal design method is useful. Another problem of multipath fading is also solved by the proposed method, because the filter output has no sidelobe in the small shift terms. A signal design method is proposed by using a complete complementary code. Using the proposed method, we can design binary CDMA signals for far wider shifts of without sidelobe nor co-channel interference. In fact, the length of shifts without the influence of multipath is 2/sup n/ for any n.
Bacterial periplasmic permeases belong to a family of transport proteins operating from<i>Escherichia coli</i>to human: Traffic ATPases (1990)

Bacterial periplasmic transport systems are complex permeases composed of a soluble substrate-binding receptor and a membrane-bound complex containing 2-4 proteins. Recent developments have clearly demonstrated that these permeases are energized by the hydrolysis of ATP. Several in vitro systems have allowed a detailed study of the essential parameters functioning in these permeases. Several of the component proteins have been shown to interact with each other and the actual substrate for the transport process has been shown to be the liganded soluble receptor. The affinity of this substrate for the membrane complex is approximately 10 microM. The involvement of ATP in energy coupling is mediated by one of the proteins in the membrane complex. For each specific permease, this protein is a member of a family of conserved proteins which bind ATP. The similarity between the members of this family is high and extends itself beyond the consensus motifs for ATP binding. Interestingly, over the last few years, several eukaryotic membrane-bound proteins have been discovered which bear a high level of homology to the family of the conserved components of bacterial periplasmic permeases. Most of these proteins are known to, or can be inferred to participate in a transport process, such as in the case of the multidrug resistance protein (MDR), the STE6 gene product of yeast, and possibly the cystic fibrosis protein. This homology suggests a similarity in the mechanism of action and possibly a common evolutionary origin. This exciting development will stimulate progress in both the prokaryotic and eukaryotic areas of research by the use of overlapping procedures and model building. We propose that this universal class of permeases be called 'Traffic ATPases' to distinguish them from other types of transport systems, and to highlight their involvement in the transport of a vast variety of substrates in either direction relative to the cell interior and their use of ATP as energy source.
Common fragile sites (2003)

Aphidicolin-induced common fragile sites are site-specific gaps or breaks seen on metaphase chromosomes after partial inhibition of DNA synthesis. These fragile sites were first recognized during the early studies of the fragile X syndrome and are induced by the same conditions of folate or thymidylate stress used to induce the fragile X site. Common fragile sites are normally stable in cultured human cells. However, following induction with replication inhibitors, they display a number of characteristics of unstable and highly recombinogenic DNA. From the many studies that have cloned and characterized fragile sites, it is now known that these sites extend over large regions, are associated with genes, exhibit late or delayed replication, and contain regions of high flexibility but are otherwise unremarkable in sequence. Studies showing that fragile sites and their associated genes are frequently deleted or rearranged in cancer cells have clearly demonstrated their importance in genome instability in tumorigenesis. Yet until recently, very little was known about the molecular mechanisms involved in their stability. Recent findings showing that the key checkpoint genes ATR and BRCA1 are critical for genome stability at fragile sites have shed new light on these mechanisms and on the biological significance of common fragile sites.
Immunophenotyping of Human Bone Marrow‐Derived Macrophages (1996)

In vitro cultured cells derived from human bone marrow stimulated with macrophage-colony stimulating factor (M-CSF) or granulocyte-macrophage-colony stimulating factor (GM-CSF) were investigated for their immunophenotypic surface characteristics by flow cytometry. Approximately 80-90% of the cells showed morphological and histochemical features of macrophages and bore CD11a, CD11b, CD11c, CD14, CD29, CD32, CD33, CD44, CD45, CD54, CD64, CD71, HLA-DR antigen. The expression of CD4, CD25 and CD45RO were detected only in low density. Bone marrow-derived macrophages were negative for CD8, CD45RA, CD16 and CD23. Functionally, macrophages were able to phagocytose opsonized Escherichia coli, but no oxidative bursts were induced either by fmlp or by opsonized bacteria. Cell surface phenotyping revealed a CD pattern very similar to monocyte-derived phagocytes, and was partially distinct from resident stromal macrophages.
The 30-year History of the Alliance des Chorales du Quebec and Its Impact on Choral Singing in the Province (2005)

The year 2004 marked the 30 th anniversary of Quebec's choral federation, the Alliance des chorales du Quebec (ACQ).Over the years it has grown from a membership of some 50 choirs to more than 200 (204 at the end of the 2004-2005 season).Its member choirs represent a wide range of repertoire, skill levels and age groups.Although there are other choral organizations in Quebec, l it is the only one officially recognized by the provincial government as the voice for the collective interests of choirs.This paper explores the federation's 30-year history, the growth and evolution of its mandate and programs and its impact on choral music in Quebec.The organization's publications and annual reports served as a major source of information.The Choral Landscape in French Canada Before 1974 Choral music has long been an integral part of French Canadian cultural activity.References to choral music written and arranged in Canada date back to the French colony at Port-Royal in 1606.The seventeenth and eighteenth centuries saw the performance of choral music imported from Europe, as well as

Affinity Chromatography of Trypsin and Related Enzymes: III. Purification of Streptomyces griseusTrypsin Using an Affinity Adsorbent Containing a Tryptic Digest of Protamine as a Ligand1 (1976)

A new, simple method has been developed for the purification of Streptomyces griseus trypsin [EC 3.4.21.4] from Pronase. Only a single operation of affinity chromatography on an agarose derivative, which was easily prepared by coupling a tryptic digest of salmine to cyanogen bromide-activated Sepharose 4B, was required. A high degree of homogeneity was demonstrated for the purified enzyme by disc electrophoresis, SDS-polyacrylamide gel electrophoresis and gel filtration, as well as by active-site titration. The behavior of a carboxypeptides B [EC 3.4.12.3]-like enzyme present in Pronase is also discussed.
Instrumentation for space (1999)

The primary drivers for space instruments are the environment and survivability, support assets, delivery cost, and lack of accessibility. Survivability deals primarily with environments, such as launch and depressurization, extremes of temperature, high vacuum, radiation, and hypervelocity impacts. The cost to deployment is directly coupled to launch services, which are inherently expensive. These costs are nonlinear functions of the mass and volume of satellite payloads. The "user interfaces" for space-borne instruments are high-cost assets because they include mission operations centers, satellite hacking station(s), and ground networks. All of these issues demand high reliability.
On‐line biosensors for simultaneous determination of glucose, choline, and glutamate integrated with a microseparation system (2003)

An effective microseparation system integrated with ring-disc electrodes and two microfluidic devices was fabricated for in vivo determination using a microdialysis pump. The major interference of ascorbic acid (AA) was excluded by direct oxidation with ascorbate oxidase. Glucose, glutamate, and choline were successfully determined simultaneously through the biosensors modified with a bilayer of osmium-poly(4-vinylpyridine)gel-horseradish peroxidase (Os-gel-HRP)/glucose oxidase (GOD), glutamate oxidase (GlutaOD) or choline oxidase (ChOD). To stabilize the biosensors, 0.2% polyethylenimine (PEI) was mixed with the oxidases. The cathodic currents of glucose, glutamate, and choline biosensors started to increase after the standard solutions were injected into the microseparation system. The on-line biosensors show a wide calibration range (10(-7)-10(-5) mol/L) with a detection limit of 10(-8) mol/L at the working potential of -50 mV. The variations of glucose, glutamate, and choline were determined simultaneously in a free moving rat when we perfused the medial frontal cortex with 100 micro mol/L N-methyl-D-aspartate (NMDA) solution, which is the agonist of the NMDA receptor.
FFT-based digital clock recovery for coherent transmission systems with multilevel modulation formats (2009)

A Heuristic for Minimizing the Number of Tool Switches on a Flexible Machine (1988)

Abstract This paper addresses the problem of scheduling N jobs on a single machine equipped with an automatic tool interchange mechanism. We consider the case where the total number of tools required to process all N jobs is greater than the capacity of the tool magazine, and where processing times and switching times are independent. The underlying problem is to find the job sequence and tool replacement policy that minimizes the total number of switches. This is equivalent to minimizing the makespan. Two industrial applications of the model are cited. The problem is formulated as a nonlinear integer program and solved with a dual-based relaxation heuristic designed to quickly find good local solutions. An example is given to highlight the computations and a series of test cases is examined to gauge the performance of the proposed methodology. The results demonstrate that in almost all cases global optimality is obtained, but in notably less time than current techniques admit. This points up the practicality of using the algorithm for real time control. Extensions to the L-machine scheduling problem are also discussed.
Bell Pepper Production in California (2008)

California has four main bell pepper (Capsicum annuum L.) production areas: the southern desert valleys (Imperial and Riverside Counties), Ventura County on the southern coast, the central coast (San Luis Obispo, Monterey, San Benito, and Santa Clara Counties), and the Central Valley (Kern, Fresno, and San Joaquin Counties
Large-scale path planning for Underwater Gliders in ocean currents (2009)

Underwater gliders are a class of AUVs designed for high endurance over long distances, but their reduced velocity makes them more susceptible to ocean currents during deployment. Thus, feasible paths need to be generated through the ocean current field. This paper proposes a method for determining energy-optimal paths that account for the influence of ocean currents. The proposed technique is based on Rapidly-Exploring Random Trees (RRTs). Using real ocean current and bathymetry data, results produce comparable paths to grid based methods, and offer an improvement in terms of avoiding high-energy shallow regions. Future work will focus on heuristically biasing the RRT growth to further improve the generated paths, and implementation of the algorithms on a glider platform.
OSPF-style database exchange and reliable synchronization in the optimized link-state routing protocol (2005)

The optimized link-state routing protocol (OLSR) is a proactive link-state routing protocol. While similar to the well-known Internet routing protocol OSPF, OLSR is designed to be simple, and to maintain connectivity in face of highly dense and dynamic networks, while being resource-economic (battery, bandwidth etc.) These characteristics make OLSR suitable as an underlaying routing protocol in a wide range of ad-hoc sensor networks. In this paper, we introduce an extension to OLSR: OSPF-style database exchange and reliable synchronization. The goal of this extension is to provide a mechanism, through which nodes in an ad-hoc sensor network can detect and correct discrepancies in their link-state databases. We qualify why the mechanism, found in OSPF, is not directly applicable for ad-hoc sensor networks, describe an adopted mechanism, accomplishing the same goal, and evaluate the performance of this mechanism in comparison to the database exchange mechanism found in OSPF. We finally discuss some applications of database exchange and reliable synchronization in ad-hoc sensor networks.
Coding Artifact Reduction Based on Local Entropy Analysis (2007)

Coding artifacts are very annoying in highly compressed images and video sequences. Most artifact reduction techniques blur the details of the images while removing various coding artifacts. In this paper, we propose a novel and explicit approach for classifying blocks into detailed regions, intermediate regions and smooth regions. The classification is based on the information content of the underlying region. The information content of a region is quantized by local entropy, which is calculated on the PDF of the pixel intensity distribution. Local entropy is used as an indicator of how much smoothing is needed for a certain region. It is well known that blocking artifacts are more visible in flat regions than in detailed regions. We apply mild low-pass filters on detailed regions to preserve the sharpness, and strong low-pass filters on flat regions to remove the severe blocking artifacts. Experimental results show that our proposed algorithm can preserve the details and reduce coding artifacts better than more expensive state of the art techniques .
Cronobacter Species Contamination of Powdered Infant Formula and the Implications for Neonatal Health (2015)

Cronobacter is a class of Enterobacteriaceae that cause infections in neonates, especially those born prematurely. Over 90% of these infections have been linked epidemiologically to powdered infant formula (PIF). Contamination of PIF can occur at manufacture, reconstitution, or storage of reconstituted product. Intrinsic properties that enable Cronobacter to cause disease include resistance to heat, ultraviolet radiation, oxygen radicals, stomach acids, and pasteurization; an ability to utilize sialic acid (a nutrition additive to PIF that facilitates the organism's growth and survival), and an exceptional affinity for biofilms in enteral feeding tubes. As part of ongoing endeavors to reduce the incidence of neonatal PIF-associated Cronobacter infections, the World Health Organization and the US Food and Drug Administration have established guidelines for PIF production, preparation for infant feeding, and storage of reconstituted product.
Adapting the Edinburgh Geoparser for Historical Georeferencing (2015)

Place name mentions in text may have more than one potential referent (e.g. Peru, the country vs. Peru, the city in Indiana). The Edinburgh Language Technology Group (LTG) has developed the Edinburgh Geoparser, a system that can automatically recognise place name mentions in text and disambiguate them with respect to a gazetteer. The recognition step is required to identify location mentions in a given piece of text. The subsequent disambiguation step, generally referred to as georesolution, grounds location mentions to their corresponding gazetteer entries with latitude and longitude values, for example, to visualise them on a map. Geoparsing is not only useful for mapping purposes but also for making document collections more accessible as it can provide additional metadata about the geographical content of documents. Combined with other information mined from text such as person names and date expressions, complex relations between such pieces of information can be identified. The Edinburgh Geoparser can be used with several gazetteers including Unlock and GeoNames to process a variety of input texts. The original version of the Geoparser was a demonstrator configured for modern text. Since then, it has been adapted to georeference historic and ancient text collections as well as modern-day newspaper text. 1 , 2 , 3 , 4 Currently, the LTG is involved in three research projects applying the Geoparser to historical text collections of very different types and for a variety of end-user applications. This paper discusses the ways in which we have customised the Geoparser for specific datasets and applications relevant to each project.
Distributed Multiversion Optimistic Concurrency Control for Mobile Real-Time Database Systems (2007)

In this paper, DMVOCC-MDA-2PLV protocol is proposed for processing mobile distributed real-time transaction in mobile broadcast environments. The new protocol can eliminate conflicts between mobile read-only and mobile update transactions, and resolve data conflicts flexibly using multiversion dynamic adjustment of serialization order to avoid unnecessary restarts of transactions. Mobile read-only transactions can be committed with no-blocking. Respond time of mobile read-only transactions is greatly improved. The tolerance of mobile transactions of disconnections from the broadcast channel is increased. The simulation results show that the new concurrency control protocol proposed offers better performance than other protocols.
MUDs grow up: social virtual reality in the real world (2002)

MUDs, or "multi-user dungeons", are multi-user, text-based, networked computing environments that are currently used mostly for gaming. Despite the obvious shortcomings of a text-only system, they are quite popular. The Social Virtual Reality project at Xerox PARC is extending MUD technology for use in non-recreational settings. Our goal is to keep the strength of MUDs/spl minus/shared computing with a powerful real-world metaphor/spl minus/while correcting their shortcomings by adding audio, video, and interactive windows. We are building two specific prototypes: Astro-VR, for use by the professional astronomy community, and Jupiter, for use by researchers within Xerox.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Cognitive Manager for Hierarchical Cluster Networks Based on Multi-Stage Machine Method (2014)

Apart from efficient use of assigned spectral resources as a primary user, Cognitive Radio (CR) has the ability to act as a secondary user, utilizing available radio resources, which are not used by primary users for a certain period of time. This paper refers to mobile CR network management, based on multi-stage machine method. The article shows the idea of the Cognitive Manager (CM), consisting of three logical modules: Clustering (CL), Clusters Graph Coloring (CGC) and Supervisor (SP) with Sensing Client (SC). SP is responsible for management of all other cognitive manager blocks. This paper describes the SP structure and its cooperation with other CM modules. Prepared simulation scenarios take into account the propagation phenomena and presence of other users and jammers, that can use the same frequency channels as CR network. The events like lack of communication between nodes, bad links quality and presence of jamming, cause the appropriate reaction of SP. In such cases, SP performs analysis of current situation, and if necessary, it changes actual used frequency (color) using backup channels list, which is permanently updated. The presented idea has been implemented in the CORASMA (Cognitive Radio for dynamic Spectrum Management) simulator.
[The inhalation administration of liposomes for the transport of broncholytic preparations in bronchial asthma]. (1997)

Effectiveness of free and capsule phenoterol B2-agonist in experimental bronchial asthma has been assessed in vitro and in vivo in rats and rabbits using different liposomes: from egg lecithin, total phospholipids from pig or human lung. It was found that free phenoterol stabilizes mast cell (MC) condition, but has no antiinflammatory effect. Utilization of empty phospholipid vesicles brings both MC stabilization and decline of inflammation in the airways. In packing phenoterol in the liposomes antiinflammatory and membrane-stabilizing effects noticeably improved. It may be due to synergistic effects of the beta-agonist and phosphatidylcholine which is the base of liposome. The discussion covers mechanisms of high efficacy of homologous liposomes.
Fully Private Noninteractive Face Verification (2013)

Face recognition is one of the foremost applications in computer vision, which often involves sensitive signals; privacy concerns have been raised lately and tackled by several recent privacy-preserving face recognition approaches. Those systems either take advantage of information derived from the database templates or require several interaction rounds between client and server, so they cannot address outsourced scenarios. We present a private face verification system that can be executed in the server without interaction, working with encrypted feature vectors for both the templates and the probe face. We achieve this by combining two significant contributions: 1) a novel feature model for Gabor coefficients' magnitude driving a Lloyd-Max quantizer, used for reducing plaintext cardinality with no impact on performance; 2) an extension of a quasi-fully homomorphic encryption able to compute, without interaction, the soft scores of an SVM operating on quantized and encrypted parameters, features and templates. We evaluate the private verification system in terms of time and communication complexity, and in verification accuracy in widely known face databases (XM2VTS, FERET, and LFW). These contributions open the door to completely private and noninteractive outsourcing of face verification.
A CMOS single-chip wireless solution with an adaptive purity-control scheme against ISM-band interferences (2006)

The authors present a Bluetooth (BT) single-chip solution to improve the immunity to ISM-band interferences. A transceiver with a purity-controllable local oscillator is proposed. The purity control scheme is experimentally verified through the firmware which controls the interference-transfer function and adjusts the allowable interference level adaptively. This solution is fully integrated in a 0.25-mu m CMOS process, and it satisfies the specification of the BT v1.2, with the optimal power consumption and the yield enhancement.
