Multiple classifiers systems with granular neural networks (2013)

Hybridization of neural networks and fuzzy sets has proved its efficiency in solving different pattern classification tasks, which led to the development of granular neural networks (GNNs). GNN works with the principles of granular computing and basically operates on granules of information. The present paper proposes an efficient multiple classifier system (MCS) framework with different guiding rules based GNNs. The performance of the proposed MCS is demonstrated and its superiority over individual GNNs is justified with remote sensing data for five land use/cover classes. Conventional back propagation algorithm is used to train the networks.
Advances in automated error assessment of spherical near-field antenna measurements (2013)

Over the years, spherical near-field (SNF) antenna measurements have become increasingly popular for characterizing a wide variety of antenna types. The SNF configuration allows one to measure data over a sphere surrounding the antenna, which provides it a unique advantage over planar and cylindrical near-field systems where measurement truncation is inherent. Like all antenna measurement configurations, SNF systems are susceptible to a number of measurement errors that, if not properly understood, can corrupt the antenna's far-field parameters of interest (directivity, beamwidth, beam pointing, etc.). The NIST 18-term error assessment originally developed for planar near-field measurements [1] has been adapted for SNF systems [2] and provides an accurate measure of the uncertainty in a particular SNF measurement. Once particular measurement errors are known, steps can be taken to reduce their impact on far-field radiation patterns. When manually assessing all 18 terms of the NIST uncertainty budget this procedure becomes tedious and time consuming. This paper will describe an acquisition algorithm that allows one to analyze all 18 error terms or a subset of those in automated fashion with minimal user intervention. Building upon previous research toward developing an automated SNF error assessment algorithm [3, 4], this new procedure will automatically generate tabulated and plotted uncertainty data for directivity, beamwidth and beam pointing of a particular far-field radiation pattern. Once measurement uncertainties are known, various post-processing techniques can be applied to improve far-field radiation patterns. Results will be shown for three antennas measured on large phi-over-theta SNF scanners.
Восстановление дефекта локтевого нерва путем аутонервной пластики и аутотрансплантации клеток стромальноЙ ВАСКУЛ ЯРНОЙ фракции жировой ткани (2014)

This article describes a clinical case of treating the patient with injury of ulnar nerve using a “gold standard” of microsurgery, the autonerve grafting, and transplantation of autologous cells of stromal vascular fraction (SVF) of adipose tissue. Nerve defect in 5 cm was replaced by three autonerve grafts of the sural nerve, and then autologous cells of SVF in the fibrin glue were transplanted. 1 year after operation, the patient has resumed the function of bringing the fingers, there have not been any neurogenic strain, muscle atrophy of the hand, as well as restoration of sensitivity in the autonomous zone of innervation of the ulnar nerve has been observed.
Decentralized Beamforming with Coordinated Sounding for Inter-Cell Interference Management (2014)

This1 paper presents and evaluates a decentralized beamforming design for inter-cell interference management that is highly recommended in Time Division Duplex (TDD) cellular network deployments and interference limited scenarios. The inter-cell interference mitigation in the downlink (DL) is done in a decentralized manner by sensing the Sounding Reference Signals (SRS) sent by user equipments (UEs) associated to neighboring evolved Node Bs (eNBs). The proposed technique exploits the reciprocity of the propagation radio channels, an adequate link adaptation in the uplink and a wise coordination of the SRS transmissions. In this regard, multiple methods are proposed to implement the proposed Beamforming with Coordinated Sounding (BF-CoS) in a 3GPP LTE-Advanced based network. Simulation results show significant performance gains in terms of user packet throughput with respect to no coordination schemes, without increasing the overhead and complexity because of coordination. The largest relative gains are obtained for medium-to-high traffic loads and for denser deployments.
Activation of In Vivo Kupffer Cell Function by Oral Administration of Cordyceps sinensis in Rats (1999)

We investigated the effect of water extracts of Cordyceps sinensis (WECS) on Kupffer cell function in rats. Rats were received a single i.v. injection of a colloidal carbon solution and then the clearance rate from the blood were measured. The rats had been daily administered with WECS, p.o. at a dose of 200 mg/kg for 25 days until the day before the injection of colloidal carbon. The half-life of the colloidal carbon in the blood of rats administered WECS 200 mg/kg was significantly shorter than that of the control rats. This suggests that accelerated function of Kupffer cells is partially involved in the anti-metastatic action of WECS.

Exploring programming model-driven QoS support for NoC-based platforms (2010)

Networks-on-Chip (NoCs) are being increasingly considered as a central enabling technology to communication-centric designs as more and more IP blocks are integrated on the same SoC. Embedded applications, in turn, are becoming extremely sophisticated, and often require guaranteed levels of service and performance. The complex and non-uniform nature of network traffic generated by parallel applications running on a large number of possibly heterogeneous IPs makes a strong case for providing Quality of Service (QoS) support for traffic streams over the NoC infrastructure.&#13;\n&#13;\nIn this paper we consider an integrated hardware/software approach for delivering QoS at the application level. We designed NoC hardware support, low-level middleware and APIs which enable QoS control at the application level. Furthermore, we identify a set of programming abstractions useful to associate the notion of priority to each running task in the system. An initial implementation of this programming model is also presented, which leverages a set of extensions to a MPSoC-specific OpenMP compiler and runtime environment.

Recent advances from Olivetti research (1992)

When the Olivetti Research Laboratory in Cambridge (ORL) was founded in 1986, its initial members had, over the previous few years, been heavily involved with the development of the Cambridge Model Distributed System: an experiment in distributed computing based on the 10 Mbps Cambridge Ring. More recently, they had also been involved in the design of the 100 Mbps Cambridge Fast Ring (CFR) which was then at a prototype stage. Networking formed the main focus of the new research laboratory. From this background in networking and distributed systems came an interest in multimedia: the Cambridge Ring had allowed a small number of experiments with audio and slow-scan video, but the bandwidths available were too limiting. The CFR, for the first time, gave sufficient bandwidth to begin research into distributed multimedia systems-research which led directly to Pandora project. More recently, the experience with slotted rings has been applied to the area of asynchronous transfer mode (ATM) networks: implementations which run at 100 Mbps over twisted pair, coaxial or optical fibre cable already exist, and research is also in progress to investigate running ATM protocols over radio and infra-red based wireless networks.
Tumor necrosis factor α Inhibition for Alzheimer’s Disease (2017)

Tumor necrosis factor α (TNF-α) plays a central role in the pathophysiology of Alzheimer's disease (AD). Food and Drug Administration-approved biologic TNF-α inhibitors are thus a potential treatment for AD, but they do not cross the blood-brain barrier. In this short review, we discuss the involvement of TNF-α in AD, challenges associated with the development of existing biologic TNF-α inhibitors for AD, and potential therapeutic strategies for targeting TNF-α for AD therapy.
Underestimated awakening face-edema caused by a mediastinal syndrome (2019)

The "mediastinal syndrome" is an oncological urgency but, in some situations as in the case report described below, it can present itself in a subtle and inextricable way with symptoms and signs that, if singularly evaluated, can be nonspecific. In particular, we report the case of facial edema and a rash that, developing in an unusual and progressive way during about 2 months, concealed a voluminous mediastinal formation due to the localization of non-Hodgkin B-cell lymphoma that caused a "superior caval vein syndrome".
An integrated navigation system manager using federated Kalman filtering (2002)

A federated Kalman filter architecture has been developed in which the Kalman filter processing is distributed among the navigation sensors to be integrated. Each navigation sensor with its Kalman filter can, in conjunction with the reference INS (Inertial Navigation System), be considered as a subsystem which functions as an independent manager. A central data fusion function is used to integrate the information from these navigators. Such a federated architecture can offer a number of advantages over one with a single central Kalman filter. These advantages include improved failure detection and correction, improved redundancy management, and lower costs for system integration. GEC Avionics has developed a system for the integration of INS with GPS (Global Positioning System) and TRN (Terrain Referenced Navigation), together with other navigation aids. Results are presented to demonstrate the performance and the benefits of using a federated approach.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Analysis and Implementation of Fine-grained Distributed Maximum Power Point Tracking in Photovoltaic Systems (2011)

This thesis deals with quantifying the merits of Distributed Maximum Power Point Tracking (DMPPT), as well as providing solutions to achieve DMPPT in PV systems. A\ngeneral method based on 3D modeling is developed to determine the energy yield of PV\ninstallations exploiting different levels of DMPPT granularity. Sub-string-level DMPPT\nis shown to have up to 30% more annual energy yield than panel-level DMPPT. A\nMulti-Input-Single-Output (MISO) dc-dc converter is proposed to achieve DMPPT in\nparallel-connected applications. A digital current-mode controller is used to operate the MISO converter in pseudo-CCM mode. For series-connected applications, the virtualparallel concept is introduced to utilize the robustness of the parallel connection. This concept is demonstrated on a three-phase boost converter. The topology offers reduced output voltage ripple under shading which increases the life-time of the output capacitor.\nThe prototypes yield output power benefits of up to 46% and 20% for the tested shading\nconditions.
SarA and not σB is essential for biofilm development by Staphylococcus aureus (2003)

Staphylococcus aureus biofilm formation is associated with the production of the polysaccharide intercellular adhesin (PIA/PNAG), the product of the ica operon. The staphylococcal accessory regulator, SarA, is a central regulatory element that controls the production of S. aureus virulence factors. By screening a library of Tn917 insertions in a clinical S. aureus strain, we identified SarA as being essential for biofilm development. Non-polar mutations of sarA in four genetically unrelated S. aureus strains decreased PIA/PNAG production and completely impaired biofilm development, both in steady state and flow conditions via an agr-independent mechanism. Accordingly, real-time PCR showed that the mutation in the sarA gene resulted in downregulation of the ica operon transcription. We also demonstrated that complete deletion of sigmaB did not affect PIA/PNAG production and biofilm formation, although it slightly decreased ica operon transcription. Furthermore, the sarA-sigmaB double mutant showed a significant decrease of ica expression but an increase of PIA/PNAG production and biofilm formation compared to the sarA single mutant. We propose that SarA activates S. aureus development of biofilm by both enhancing the ica operon transcription and suppressing the transcription of either a protein involved in the turnover of PIA/PNAG or a repressor of its synthesis, whose expression would be sigmaB-dependent.
Pixel structure and layout for CMOS active pixel image sensor (1998)

Shrinkage of pixel structures and layouts for CMOS active pixel image sensors are studied. Reduction of CMOS device design rule with the scaling-law can make the pixel size small, naturally. However, using minimum design rule, quarter micron rule or sub quarter micron rule, costs expensive. Therefore, pixel size shrinkage using relatively rough design rule have been studied for reduction of the chip cost. We have already reported about small pixel structure by replacement of row-select transistor by row- select capacitor, by omission of reset transistor with forward bias reset operation, and by omission of reset transistor with pinned-buried reset channel. We have also reported about small pixel by high packing density layout named 'I-shaped cell' and its zigzag layout. However, these pixel shrinkage have some disadvantages. In this paper, we propose a novel pixel structure driven by pulse operation of drain line for row select and reset. Conventional row select structure, row select transistor or row select capacitor, is omitted by the row-select channel that contains low impurity concentration and has no gate structure. Moreover, conventional reset transistor is also replaced by reset channel structure in like manner. These structures and triple level pulse operation of drain realize quite simple pixel structure in which amplification transistor is the only gate structure. A large fill factor of 37 percent is obtained by this structure, in 5.6 micrometers X 5.6 micrometers pixel designed by 0.7 micrometers rule.
PLANT GROWTH RESPONSE IN EXPERIMENTAL SOILLESS MIXES PREPARED FROM COAL COMBUSTION PRODUCTS AND ORGANIC WASTE MATERIALS (2008)

Large quantities of organic materials such as animal manures, yard trimmings, and biosolids are produced each year. Beneficial use options for them are often limited, and composting has been proposed as a way to better manage these organic materials. Similarly, burning of coal created 125 million tons of coal combustion products (CCP) in the United States in 2006. An estimated 53 million tons of CCP were reused, whereas the remainder was deposited in landfills. By combining CCP and composted organic materials (COM), we were able to create soilless plant growth mixes with physicochemical conditions that can support excellent plant growth. An additional benefit is the conservation of natural raw materials, such as peat, which is generally used for making soilless mixes. Experimental mixes were formulated by combining CCP and COM at ratios ranging from 2:8 to 8:2 (vol/vol), respectively. Water content at saturation for the created mixes was 63% to 72%, whereas for the commercial control, it was 77%. pH values for the best performing mixes ranged between 5.9 and 6.8. Electrical conductivity and concentrations of required plant nutrient were also within plant growth recommendations for container media. Significantly (P < 0.0001) higher plant biomass growth (7%-130%) was observed in the experimental mixes compared with a commercial mix. No additional fertilizers were provided during the experiment, and reduced fertilization costs can thus accrue as an added benefit to the grower. In summary, combining CCP and COM, derived from source materials often viewed as wastes, can create highly productive plant growth mixes.
Some new structure-type targets for the vidicon&#8212;Analysis of their operation (1958)

Severe physical requirements are imposed on the photoconductive layer used in the conventional vidicon camera tube target. In particular, its resistivity must be of the order of 1012ohm-cm for frame storage operation and its thickness must be sufficient to prevent capacitive lag. New vidicon targets of a complex structure permit a relaxation of these requirements on the photoconductor. Two types of targets are discussed. 1) An experimental lateral-flow structure in which the photocurrent flows parallel to the target plane instead of transversely as in the standard vidicon. 2) An experimental bridge-type structure in which each picture element provides an internal closed circuit so that the charge pattern is established independently of the scanning beam.
A population neuroscience approach to the study of cerebral small vessel disease in midlife and late life: an invited review (2018)

Aging in later life engenders numerous changes to the cerebral microvasculature. Such changes can remain clinically silent but are associated with greater risk for negative health outcomes over time. Knowledge is limited about the pathogenesis, prevention, and treatment of potentially detrimental changes in the cerebral microvasculature that occur with advancing age. In this review, we summarize literature on aging of the cerebral microvasculature, and we propose a conceptual framework to fill existing research gaps and advance future work on this heterogeneous phenomenon. We propose that the major gaps in this area are attributable to an incomplete characterization of cerebrovascular pathology, the populations being studied, and the temporality of exposure to risk factors. Specifically, currently available measures of age-related cerebral microvasculature changes are indirect, primarily related to parenchymal damage rather than direct quantification of small vessel damage, limiting the understanding of cerebral small vessel disease (cSVD) itself. Moreover, studies seldom account for variability in the health-related conditions or interactions with risk factors, which are likely determinants of cSVD pathogenesis. Finally, study designs are predominantly cross-sectional and/or have relied on single time point measures, leaving no clear evidence of time trajectories of risk factors or of change in cerebral microvasculature. We argue that more resources should be invested in 1) developing methodological approaches and basic science models to better understand the pathogenic and etiological nature of age-related brain microvascular diseases and 2) implementing state-of-the-science population study designs that account for the temporal evolution of cerebral microvascular changes in diverse populations across the lifespan.
Generation of paternal dihaploids in tall fescue (2016)

Abstract Within the Lolium ‐ Festuca genome complex there is a need for modern breeding approaches that can facilitate the rapid development of improved germplasm or cultivars. Traditional recurrent or mass‐selection methods for population or synthetic development are labor intensive and time consuming. The recent development of dihaploid ( DH ) inducer lines of annual ryegrass ( Lolium perenne L. subsp. multiflorum (Lam.) Husnot [syn. Lolium multiflorum Lam.]) that exhibit genome loss when hybridized with tall fescue ( Lolium arundinaceum (Schreb.) Darbysh. [syn. Festuca arundinacea Schreb.]) can provide an alternative breeding approach. Hybridizations between the inducer lines and tall fescue result in F 1 hybrids that can lose either their ryegrass or tall fescue genomes. This behavior results in the occasional generation of both ryegrass and tall fescue DH lines through parthenogenic embryo formation within the F 1 inflorescence.
Convergence Acceleration of Time-Periodic Electromagnetic Field Analysis by the Singularity Decomposition-Explicit Error Correction Method (2010)

This paper proposes a novel method for the improvement of the convergence to a steady state in time-periodic transient nonlinear eddy-current analyses. The proposed method, which is based on the time-periodic finite element method and the singularity decomposition-explicit error correction method, can extract poorly converged error components corresponding to the large time constants of an analyzed system. The correction of the extracted error components efficiently accelerates the convergence to a steady state. Numerical results verify the effectiveness of the proposed method.
BRDF measurement of highly-specular materials using a goniometer (2017)

Visually accurate capture of appearance of highly specular surfaces is of a great research interest of the coating industry, who strive to introduce highly reflective products while minimizing their production and quality assessment costs, and avoiding environmental issues related to the production process. An efficient measurement of such surfaces is challenging due to their narrow specular peak of an unknown shape and typically very high dynamic range. Such behavior puts higher requirements on capabilities of a measuring device and has impact on length of the measurement process. In this paper, we rely on a material probes with a predefined curved shape featuring slight local inhomogeneities. This defines a goniometric device as appropriate means of appearance capture. To shorten a typically long measurement time required when using these approaches, we introduce a method of material appearance acquisition by means of the isotropic BRDF using relatively sparse sampling adapted to each measured material individually.
Seismic Observation of Infrasonic Signals (1984)

Abstract : A sliding pure-state filter attenuated wind-induced noise recorded by individual elements of a four-element microbarograph array an average of 22 dB. Summation of the processed microbarograms yielded an additional 5 dB attenuation, whereas summation of the unprocessed microbarograms attenuated the noise 6 dB relative to the individual microbarograms. A sliding pure-state filter yielding separate estimates of linearly and elliptically polarized arrivals, applied to the outputs of three-component, long-period inertial seismographs at a site near McKinney, Texas, and at Seismic Research Observatories ANMO, BOCO, and GRFO detected infrasonic signals from five eruptive sequences of E1 Chichon volcano. Application of the pure-state filter improved the signal-to-noise ratio of the seismically detected infrasonic signals an average of 14 dB. A combination of adaptive beam forming and pure- state filtering applied to the outputs of the seven elements of the NORSAR three-component, long-period array marginally detected an infrasonic signal from the largest E1 Chichon eruption.
