Electrical Characteristics of Carbon Nanotubes by Plasma and Microwave Surface Treatments (2014)

The plasma and microwave surface treatments of carbon nanotubes that loaded on plastic substrates were carried out with expecting a change of carbon nanotube dispersion by increasing treatment time. The microwave treatment process was undergone by commercial microwave oven (800 W). The electrical property was measured by hall measurement and resistance was increased by increasing <TEX>$O_2$</TEX> flow rate of plasma, suggesting an improvement of carbon nanotube dispersion and a possibility of controlling the resistances of carbon nanotubes by plasma surface treatment. The resistance was increased in both polyethylene terephthalate and polyimide substrates by increasing <TEX>$O_2$</TEX> flow rate. Resistance changes only slightly with different <TEX>$O_2$</TEX> flow treatment in measure rho for all polyimide samples. Sheet resistance is lowest in polyimide substrate not due to high carbon nanotube loading but due to tendency to remain in elongated structure. <TEX>$O_2$</TEX> or <TEX>$N_2$</TEX> plasma treatments on both polyethylene terephthalate and polyimide substrates lead to increase in sheet resistance.
A DOUBLE-BLIND STUDY OF THE EFFECTIVENESS OF LOW LEVEL LASER TREATMENT OF ROTATOR CUFF TENDINITIS (1993)

Thirty-five patients with rotator cuff tendinitis were randomly allocated to active (CB Medico Master III 830 nm Ga As AL diode) laser or dummy laser treatment twice weekly for 8 weeks. Movement range, painful arc score, resisted movement score and responses to visual analogue scales for night pain, rest pain, movement pain and functional limitation were measured second weekly. All responses improved from baseline but there was no difference between the two groups. These results fail to demonstrate the effectiveness of laser therapy in rotator cuff tendinitis.
Membrane Progesterone Receptors: Evidence for Neuroprotective, Neurosteroid Signaling and Neuroendocrine Functions in Neuronal Cells (2012)

Membrane progesterone receptors (mPRs) are novel G protein-coupled receptors belonging to the progestin and adipoQ receptor family (PAQR) that mediate a variety of rapid cell surface-initiated progesterone actions in the reproductive system involving activation of intracellular signaling pathways (i.e. nonclassical actions). The mPRs are highly expressed in the brain, but research on their neural functions has only been conducted in a single neuronal cell line, GT1-7 cells, which have negligible nuclear progesterone receptor (PR) expression. GT1-7 cells express mPRα and mPRβ on their plasma membranes which is associated with the presence of high-affinity, specific [(3)H]-progesterone receptor binding. The neurosteroid, allopregnanolone, is an effective ligand for recombinant mPRα with a relative binding affinity of 7.6% that of progesterone. Allopregnanolone acts as a potent mPR agonist on GT1-7 cells, mimicking the progesterone-induced decrease in cAMP accumulation and its antiapoptotic actions at low nanomolar concentrations. The decrease in cAMP levels is associated with rapid progesterone-induced downregulation of GnRH pulsatile secretion from perifused GT1-7 cells. The recent suggestion that mPRs are alkaline ceramidases and mediate sphingolipid signaling is not supported by empirical evidence that TNFα does not bind to mPRs overexpressed in human cells and that exogenous sphingomyelinase is ineffective in mimicking progestin actions through mPRs to induce meiotic maturation of fish oocytes. Taken together, these recent studies indicate that mPRs mediate neuroprotective effects of progesterone and allopregnanolone and are also the likely intermediaries in progesterone-induced inhibition of pulsatile GnRH secretion in GT1-7 cells.
Totally Drug-Resistant and Extremely Drug-Resistant Tuberculosis: The Same Disease? (2012)

The present debate on the new definition has an advocacy taste on top of its scientific interest. Looking at the media messages reported worldwide over the last weeks, we realized that the terms TDR tuberculosis and XXDR tuberculosis were used to generate interest in the average news reader—as well as probably anxiety or panic. The tuberculosis control community needs clear definitions, which reflect clinical and operational facts and support the laboratory, clinical, and public health efforts to prevent the emergence of drug resistance and to cure the resistant cases we have already produced.
Fault-tolerant operation of a 150 kW 3-level neutral-point clamped PWM inverter in a flywheel energy storage system (2002)

This paper proposes a fault-tolerant operation strategy of three-level neutral-point-clamped PWM inverters in high power, high performance, safety-critical applications. Likely faults are identified and fault-tolerant schemes based on the inherent redundancy of voltage vectors of neutral-point-clamped inverters are presented. Simulation verification is performed and shows good fault handling capability. A 150 kW neutral-point-clamped inverter is constructed for flywheel energy storage applications. Experimental testing of the fault-tolerant operation strategy is in progress.
Identifying Patterns of Workflow Design Relying on Organizational Structure Aspects. (2003)

Abstract: Modern organizations have demands of automation of their business processes, once they are highly complex and need to be efficiently executed. For this reason the number of systems based on information technologies able to provide a better documentation, standardization and co-ordination of the business process is increasing. In this context, workflow technology has been quite efficient, mainly for the automation of business processes. However, as it is an emergent technology and in constant evolution, workflow presents some limitations. One of the main limitations is the lack of techniques that guarantee correction and efficiency to the workflow project in the phases of requisite analysis and modeling. Taking into account these problems and having accomplished some studies, we formulated the hypothesis that it is possible to infer the specific workflow (sub)processes structure from knowledge on structural aspects of the organization and vice-versa. We made the verification of such hypothesis through the identification of a set of dependency rules among the aspects of the organizational structure and workflow (sub)processes. This paper presents the set of rules and the description of the technique used for the identification. 1
Regulation of human CETP gene expression (2003)

Cholesteryl ester transfer protein (CETP) is a key factor in plasma reverse cholesterol transport and is implicated in the pathophysiology of atherogenic dyslipidemia. Variations observed in plasma CETP mass and activity in both normolipidemic and dyslipidemic individuals may reflect differences in CETP gene expression. We evaluated the respective roles of the Sp1 and Sp3 transcription factors on the promoter activity of the human CETP gene at a new Sp1/Sp3 site identified at position -690, and at two previously described Sp1/Sp3 sites at positions -37 and -629. In transient transfection in HepG2 cells, site-directed mutagenesis using luciferase reporter constructs containing a promoter fragment from +32 to -745 indicated that the new -690 site acts as a repressive element in reducing CETP promoter activity (-22%; P < 0.05); equally, this site exerts an additive effect with the -629 site, inducing marked repression (-42%; P < 0.005). In contrast, in NCTC cells that display a 16-fold lower level of Sp3, the repressive effect at the -690 site was enhanced 2-fold (-45%; P < 0.05), whereas the -629 site exerted no effect. Cotransfection of Sp1 and/or Sp3 in SL2 insect cells lacking endogenous Sp factors demonstrated that Sp1 and Sp3 act as activators at the -690 and -37 sites, whereas Sp3 acts as a repressor at the -629 site. Taken together, our data demonstrate that Sp1 and Sp3 regulate human CETP promoter activity through three Sp1/Sp3 binding sites in a distinct manner, and that the Sp1/Sp3 ratio is a key factor in determining the relative contribution of these sites to total promoter activity.
Position accommodation and compliance control for robotic excavation (2005)

A robotic excavator must be able to operate in all three states of manipulator motion: free-space, contact and exertion of a force against an environment. A position accommodation control scheme is ideally suited for this task. The position accommodation method described in this study uses a position controller to track a pre-defined trajectory in the absence of a force at the excavator bucket. If a force is detected, the measured force is used, through a compliance controller, to modify the commanded trajectory. This allows for better control of the complete excavation cycle. This paper describes a rheological method for modeling the soil-bucket interaction force and how that method must be modified to suit the unique case of excavation. The results illustrate the difference between a purely position controlled robot and one using a position accommodation/compliance controller, when used to dig a level path
A translation/rotation/scaling/occlusion invariant neural network for 2D/3D object classification (1992)

Classifying objects that are distorted by similarity transforms and detection/occlusion noise is a difficult pattern recognition task. A novel and robust neural network solution based on detected surface boundary points is presented. The method operates in two stages. The object is first parametrically represented by a surface reconstruction neural network (SRNN) trained by the boundary points sampled from the exemplar object. When later presented with a distorted object, this parametric representation reduces the effects caused by detection/occlusion and also allows the mismatch information backpropagated through the SRNN to iteratively determine the best similarity transform of the distorted object. The distance measure can then be computed in the reconstructed representation domain between the exemplar object and the aligned distorted object.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Catalytic Enantioselective Hydrogenolysis of [Cr(CO)<sub>3</sub>(5,8‐Dibromonaphthalene)] (2006)

Split and run: A study of the asymmetric hydrogenolysis of an aryl-carbon–bromine bond in a naphthalene chromiumtricarbonyl complex shows the use of a new bulky phosphoramidite ligand to yield the product in highly enantiomerically enriched form (see scheme).
Introduction to the High Temperature Oxidation of Metals (2006)

A straightforward treatment describing the oxidation processes of metals and alloys at elevated temperatures. This 2006 second edition retains the fundamental theory but incorporates advances made in understanding degradation phenomena. The first half provides an authoritative introduction to the basic principles, covering thermodynamics and mechanisms of high temperature corrosion of metals and alloys. The latter half extends the discussion to oxidation processes in complex systems, from reactions in mixed environments to protective techniques, including coatings and atmosphere control. The authors provide a logical and expert treatment of the subject, producing a revised edition that will be a comprehensive guide to material scientists and engineers requiring an understanding of this elementary process.
Mortality in randomized controlled trials comparing drug-eluting vs. bare metal stents in coronary artery disease: a meta-analysis (2006)

Drug-eluting stents for the treatment of coronary artery disease do not reduce total mortality when compared with bare metal stents. Preliminary evidence suggests that sirolimus- but not paclitaxel-eluting stents may lead to increased non-cardiac mortality. Long-term follow-up and assessment of cause-specific deaths in patients receiving drug-eluting stents is mandatory to determine the long-term safety of these devices.
MEMBRANE BIOREACTORS: WASTEWATER TREATMENTAPPLICATIONS TO ACHIEVE HIGH QUALITY EFFLUENT (2001)

Membrane bioreactors (MBRs) combine the use of biological processes and membrane technology to treat wastewater. Within one process unit, a high standard of treatment is achieved, replacing the conventional arrangement of aeration tank, settling tank and filtration that generally produces what is termed as a tertiary standard effluent. The dependence on disinfection is also reduced, since the membranes with pore openings, generally in the 0.1-0.5μ μ m range, trap a significant proportion of pathogenic organisms. The more common MBR configuration is to have the membrane immersed in the wastewater, although a side stream configuration is also possible, with the wastewater pumped through the membrane module and then returned to the bioreactor. Operating at a mixed liquor suspended solids (MLSS) concentration of up to 20,000 mg/L and a sludge age of 30 -60 days, MBRs offer additional advantages over conventional activated sludge plants, including a smaller footprint.

A Fast Spline Curve Rendering Accelerator Architecture (2009)

Spline curve rendering is an essential operation in modern 2-D graphic applications. Different from the software acceleration approach by graphic processor units, this brief presents a very large scale integration hardware accelerator architecture for supporting fast curve rendering. Many existing accelerators employ a sequential forward-difference algorithm, where a step size is used in calculating the next sample on the curve. The problem of hardware-based curve rendering is that feedback loops are required to accumulate the difference, and these loops inhibit many traditional performance-enhancement strategies such as unfolding and pipelining. This brief proposes a different parallel design approach by transforming the difference equation set into parallel ones. Each equation has to be equipped with the same increased step size but accumulated starting from different initial values. Although more initial values must be precomputed, this computation can itself be sped up by using the accelerator. The proposed design can be applied not only to cubic spline curves but also to any curves defined by parameterized polynomial functions.
Optimal bipartite multi-processor implementation of recurrent DSP algorithm with fixed communication delay (2002)

A novel method is proposed to compute the theoretical minimum initiation interval of a recurrent digital signal processing (DSP) algorithm given a know, fixed inter-processor communication delay. In effect, this proposed algorithm seeks to bipartite a given cyclic graph in such a way that, after the inter-processor communication delay is taken into account, the theoretical minimum initiation interval so computed will be guaranteed to be correct, and minimized. This result made a crucial step toward the real time implementation of recurrent DSP algorithms on multi-modules with known, fixed inter-module communication delay.
Kinematics of spontaneous, reflex, and conditioned eyelid movements in the alert cat (1995)

1. Upper eyelid position and velocity, and the electromyographic (EMG) activity of the orbicularis oculi muscle, were recorded bilaterally in alert cats during spontaneous, reflexively evoked, and conditioned eyelid movements. 2. Spontaneous blinks appeared randomly (0.2-0.5 per min) and consisted of a fast, large downward lid movement followed by a slower up phase. Blinks of smaller amplitude and slower velocity were also observed mainly accompanying behavioral movements, such as during peering and grimacing. 3. Eyelid response to air puffs applied to the cornea and tarsal lid skin consisted of a short-latency (9-16 ms), fast (up to 2,000 degrees/s) downward movement that lasted for 25-30 ms, followed by late, small downward sags that were sometimes still evident after stimulus offset. Blinks outlasted the duration of the stimulus by approximately 150 ms. Blinks elicited by flashes of light or tones showed longer latency (47.3 +/- 6.3 and 53.7 +/- 8.0 ms, mean +/- SD; respectively), smaller amplitude, and a quicker habituation than air-puff-evoked lid responses. 4. For the down phase of the blink, the peak velocity, but not its duration, increased linearly with blink amplitude. Because the rise time of the down phase remained constant, changes in blink amplitude seemed to be the result of increased blink velocity. The down phase of a typical 10 degrees blink was 10 times faster than the up phase of the same blink or than upward and downward lid saccades of the same amplitude. The peak velocity and duration of the up phases of reflex blinks and upward and downward lid saccades increased linearly with lid movement amplitude. 5. The initial down phase of air-puff-evoked blinks decreased in latency, increased in amplitude and peak velocity, and maintained the same rise time for increasing puff pressure. None of these parameters was dependent on puff duration. The duration of the blink also increased linearly with air puff duration. 6. The amplitude of air-puff-evoked blinks was inversely related to lid position, decreasing with further lid positions in the closing direction. In contrast, neither peak nor integrated EMG activity of the orbicularis oculi muscle was affected by lid position, being only a function of stimulus parameters and of the animal's level of alertness. 7. Air puffs > 20 ms and > 1 kg/cm2 evoked two successive bursts (R(ap) 1 and R(ap) 2) in the EMG activity of the orbicularis oculi muscle. Shorter and/or weaker stimuli evoked only the R(ap) 1 response.(ABSTRACT TRUNCATED AT 400 WORDS)
Statistical enhancement methods for immersive audio environments and compressed audio (2015)

Over the past years, audio enhancement methods have been the center of research focus as audio reproduction systems become ever more popular. Portable music players, internet radio and multichannel surround systems are all evidence of the rapid evolution of audio rendering algorithms and their applications. In this new environment, the primary role of audio enhancement algorithms is to improve on the performance and resource allocation of audio rendering systems given application-specific transmission bandwidth and data storage constraints.
Rho GTPases in Hematopoietic Stem/Progenitor Cell Migration (2011)

Rho GTPases including RhoA, Rac1, and Cdc42 are a class of intracellular signaling proteins critical for the regulation of cytoskeleton organization, adhesion, and migration. Molecular mechanisms of mammalian cell migration were first revealed in fibroblasts where RhoA, Rac1, and Cdc42 facilitate in the multistep process including establishment and maintenance of polarity, formation of actin-rich protrusions, remodeling of adhesive contacts, and generation of force. In hematopoietic stem/progenitor cells, Rho GTPases relay signals from chemokines and cytokines such as SDF-1α and SCF to the actin and microtubule cytoskeleton through effector kinases and/or adaptor molecules that affect adhesion or transcription. Comprehensive use of murine conditional gene knockout technology combined with biochemical approaches in recent studies allows for physiologically relevant investigations of the involvement of Rho GTPases in hematopoietic stem/progenitor cell migration, providing important mechanisms for the stem/progenitor maintenance.
Amorphous Basophilic Deposit in the Superficial Dermis of the Lip in an 80 Year Old (2010)

An 80-year-old woman presented with a 3 mm pearly, translucent papule in her left upper cutaneous lip of 2 months duration which was biopsied to rule out basal cell carcinoma. Histopathologic examination revealed acellular, basophilic material in the superficial dermis, extending to the base of the biopsy. There was neither an epithelial component nor an inflammatory reaction associated with it. The amorphous, nonpolarizable material stained with Alcian Blue (pH 2.5) and with colloidal iron, but was negative with a Periodic acid-Schiff stain, indicative of an acidic mucin, such as weakly sulfated mucin of salivary gland origin or a dermal-origin mucin. The material was digested with hyaluronidase, consistent with the mesenchymal-origin mucin hyaluronic acid (HA). Additional clinical history was obtained; the patient had previous HA (Restylane) injections at another institution. We report a case of superficially applied HA and consider the histopathologic differential diagnosis of endogenous and injected mucin in the dermis.
Fighting foam with phages? (2002)

Seventeen (17) phages infective for the mycolata were isolated from six samples of activated sludge using 21 prospective hosts from the genera Dietzia, Gordonia, Nocardia, Rhodococcus, Tsukamurella and Mycobacterium. Their morphology indicated that they were all members of the viral family Siphoviridae, but they varied in the size of the icosahedral head and length of non-contractile tail, suggesting they were different. This was confirmed by host-range studies with 47 strains of mycolata, which showed that each phage had a unique host-range, and this was polyvalent in the majority (15/17) of cases, with 12 phages infective for hosts representing two or three of the genera Gordonia, Nocardia and Rhodococcus. The potential for use of these phages in the control of foaming and other applications is discussed.
Computerized Morphometric Assessment of the Effect of Low-Level Laser Therapy on Bone Repair: An Experimental Animal Study (2002)

It is concluded that, under this experimental condition, LLLT increased bone repair at early bone healing.
Transformer Fault Diagnosis by Dissolved-Gas Analysis (1980)

The great majority of incipient faults occurring in power transformers gives evidence of their presence early in their developmental stages. Oil and oil-impregnated electrical insulating materials can decompose under the influence of thermal and electrical stresses generating gaseous decomposition products which dissolve in the mineral oil. The nature and the amount of the individual component gases extracted from the oil may be indicative of the type and degree of the abnormality present [1]. One out of four transformers tested, using a gas chromatography technique, has an operational fault. Data obtained from the analysis of nearly 5000 transformers considers units ranging in size from 25 kVA-300 MVA. Case histories comparing fault diagnosis with actual conditions are cited. A method of determining the severity of the problem will be demonstrated. Over three years of experience using this method has proved the practical value of this chemical analytical tool to the power engineer.
