Robust-inversion-based 2DOF-control design for output tracking: Piezoelectric actuator example (2007)

In this article, a novel robust-inversion-based two-degree-of-freedom (2DOF)-control approach for output tracking is proposed. The inversion-based feedforward control techniques have been successfully implemented in various applications. Usually the inverse feedforward input is applied by augmenting it with a feedback controller—to account for adverse effects such as dynamics variations and disturbances. However, currently such an integration, of the feedback control to the inversion-based feedforward control, is ad-hoc, and may not lead to an optimal complementation of the feedback control with the inversion-based feedforward control. The contribution of this article is a systematic development of designing the inversion-based feedforward-feedback 2DOF controller. First, a novel robust system-inversion method is proposed which achieves a guaranteed tracking performance of the feedforward control for bounded dynamics uncertainties. Secondly, the bound of the tracking error of the feedforward control is utilized in the H <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">∞</sup> robust control framework to design the feedback controller which complements the feedforward control. Based on the concept of Bode’s integral, it is shown that the feedback bandwidth can be improved from that by using feedback alone, with no loss of tracking precision and robustness stability. We illustrate the proposed approach through experiments on a piezotube actuator used for precision positioning on an atomic force microscope (AFM).
Improving Geographical Routing for Wireless Networks with an Efficient Path Pruning Algorithm (2006)

Geographical routing is powerful for its ability to discover route to the destination without the help of global state. However, detours usually occur when the packet reaches a local minimum. In this case, the network topology has to be reduced to a planar graph and recovery schemes such as face routing are needed. However, face routing may create a large number of hops on a planar graph. When multiple packets are generated for the same destination, such a large number of hops tends to consume more energy. In this paper, a simple yet effective path pruning strategy is proposed to reduce the excessive number of hops caused by the detouring mode of geographical routing protocols. The path pruning algorithm finds routing shortcuts by exploiting the channel listening capability of wireless nodes, and is able to reduce a large number of hops with the help of little state information passively maintained by a subset of nodes on the route. The average hop count of the proposed algorithm is compared to those of existing geographical routing algorithms and the benchmark shortest path algorithm. Simulation results show that in average the path pruning algorithm can reduce as much as 80% of hops on the routes obtained by greedy perimeter stateless routing (GPSR) and greedy other adaptive face routing <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">+</sup> (GOAFR <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">+</sup> ) in a critical network density range
Synergism Between FSH and Activin in the Regulation of Proliferating Cell Nuclear Antigen (PCNA) and Cyclin D2 Expression in Rat Granulosa Cells (2001)

Follicular development is associated with both proliferation and differentiation of granulosa cells under the control of FSH. We show that regulation of genes involved in cellular proliferation by FSH can be functionally separated from the regulation of genes involved in granulosa cell differentiation by synergistic actions of activin and T. Incubation of undifferentiated rat granulosa cells with FSH, forskolin, activin-A, or T alone did not influence either the expression of the proliferation-associated genes cyclin D2 and proliferating cell nuclear antigen or the differentiation-associated genes P450 aromatase, LH receptor, P450 cholesterol side-chain cleavage enzyme, and 3 beta-hydroxysteroid dehydrogenase. However, when granulosa cells were stimulated with either FSH or forskolin in the presence of activin-A, significant increases (P < 0.05) were observed for cyclin D2 and proliferating cell nuclear antigen at both the mRNA and protein levels as well as mRNAs for P450 aromatase, LH receptor, P450 cholesterol side-chain cleavage enzyme and 3 beta-hydroxysteroid dehydrogenase. Although T synergized with FSH to increase the expression of mRNAs for P450 aromatase, LH receptor, P450 cholesterol side-chain cleavage enzyme, and 3 beta-hydroxysteroid dehydrogenase, it did not interact with FSH to increase the expression of mRNAs for cyclin D2 and proliferating cell nuclear antigen. The differences in the actions of activin and T could provide a cellular mechanism by which FSH-regulated granulosa cell proliferation could be functionally separated from FSH-regulated granulosa cell differentiation.
Design of Beam Steering n-phase OPTO-ULSI Processor for IIPS (2008)

This project investigates an optimum phase design implementing a 256 phase Opto-ULSI processor for multi-function capable optical networks. The design of an 8 phase processor is already in construction and will provide the initial base for experimentation and characterization. The challenge is to be able to compensate for the non-linearity of the liquid crystal, find an optimum phase, and implement a larger scale Opto-ULSI processor. This research is oriented around the initial development of an 8 phase Opto-ULSI processor that implements a Beam Steering(BS) Opto-ULSI processor(OUP) for integrated intelligent photonic system(IIPS), while investigating the optimal phase characteristics and developing compensation for the non-linearity of liquid crystal.
Recent trends in the metabolism and cell biology of vitamin K with special reference to vitamin K cycling and MK-4 biosynthesis (2014)

In contrast to other fat-soluble vitamins, dietary vitamin K is rapidly lost to the body resulting in comparatively low tissue stores. Deficiency is kept at bay by the ubiquity of vitamin K in the diet, synthesis by gut microflora in some species, and relatively low vitamin K cofactor requirements for γ-glutamyl carboxylation. However, as shown by fatal neonatal bleeding in mice that lack vitamin K epoxide reductase (VKOR), the low requirements are dependent on the ability of animals to regenerate vitamin K from its epoxide metabolite via the vitamin K cycle. The identification of the genes encoding VKOR and its paralog VKOR-like 1 (VKORL1) has accelerated understanding of the enzymology of this salvage pathway. In parallel, a novel human enzyme that participates in the cellular conversion of phylloquinone to menaquinone (MK)-4 was identified as UbiA prenyltransferase-containing domain 1 (UBIAD1). Recent studies suggest that side-chain cleavage of oral phylloquinone occurs in the intestine, and that menadione is a circulating precursor of tissue MK-4. The mechanisms and functions of vitamin K recycling and MK-4 synthesis have dominated advances made in vitamin K biochemistry over the last five years and, after a brief overview of general metabolism, are the main focuses of this review.

An Efficient Image Processing Method Based on Web Services for Mobile Devices (2009)

The resource limitation of mobile devices causes the problem that the existing image processing software based on the centralized computing mode had difficulty running in mobile devices. A solution is given in the paper by adopting Web service-based image processing method. For one thing, image processing tasks were distributed to service providers' service registry and service requesters. For another, what the service providers should do was only to invocate the specific image processing services provided by service providers. Consequently, Web service-based solution reduces the resource consumption of mobile devices by redistributing image processing tasks. Compared with traditional methods of image processing, Web service-based image processing method has the advantages of loose coupling and component oriented and can take full advantage of the computing resources in heterogeneous network. Thus Web service-based image processing method can effectively solve the resource bottle-neck that traditional image processing software had.
Physical properties of fixed prosthodontic, resin composite luting agents. (1994)

This study determined and compared physical properties of six fixed prosthodontic resin composite luting agents and one control. Inorganic filler content, compressive strength, diametral tensile strength, film thickness, and Knoop hardness were determined. The amounts of filler and the physical properties varied widely among materials. One material, which contained a minimal amount of filler, underwent so much plastic deformation that its strengths could not be measured. All other materials demonstrated high strengths. The materials with the least filler demonstrated the least resistance to indentation. The material with the lowest film thickness had not set at the time of measurement, 10 minutes after mixing. Most materials had unacceptable film thicknesses. Only one material demonstrated acceptable physical properties throughout the study.
Apolipoprotein A-I mimetic peptide 4F attenuates kidney injury, heart injury, and endothelial dysfunction in sepsis (2014)

Kidney injury, heart injury, and cytokine-induced vascular hyperpermeability are associated with high rates of morbidity and mortality in sepsis. Although the mechanism remains unknown, apolipoprotein A-I (apoA-I) mimetic peptide 4F reduces inflammation and protects HDL levels, which are reduced in sepsis. We hypothesized that 4F also protects kidneys and hearts in a rat model of cecal ligation and puncture (CLP). We divided Wistar rats into groups: sham-operated (control), CLP, and CLP+4F (10 mg/kg body wt ip, 6 h after CLP). At 24 h post-CLP, we evaluated cardiac function, mean arterial pressure (MAP), heart rate (HR), baroreflex sensitivity, total cholesterol, LDL, HDL, serum cytokines, and inulin clearance. We performed immunoblotting for protein regulators of vascular permeability (Slit2 and Robo4) and endothelial nitric oxide synthase (eNOS) in kidney tissue. We evaluated heart mitochondria with electron microscopy. Although there was no difference in MAP, the HR was significantly higher in CLP rats than in control and CLP+4F rats. In CLP+4F rats, baroreflex sensitivity and cardiac function were completely protected from the effects of CLP, as was glomerular filtration; heart mitochondria morphology was improved; sepsis-induced changes in serum cholesterol, LDL, HDL, and apoA-I were less common; all cytokines were lower than in CLP rats; and expression of Slit2, Robo4, and eNOS was completely restored. Administration of 4F inhibits inflammatory responses and strengthens the vascular barrier, protecting kidneys and hearts in an HDL-dependent manner. To determine the extent of the protective effect of 4F, further studies are needed.
Electrochemical Properties of the Semiconducting TiO<sub>2</sub>(Rutile) Single Crystal Electrode (1976)

Abstract The electrochemical behaviour of semiconducting TiO 2 electrodes has been investigated by means of impedance, current and potential measurements in darkness, and as well in indifferent electrolyte as in redox electrolyte solutions. The results allow the determination of the flat‐band potential and of the position of the energy band edges at the TiO 2 surface. The data obtained on electrochemical reactivity, both anodically and cathodically, appear to be qualitatively interpretable on the basis of the accepted theories for direct electron transfer at the semiconductor/electrolyte interface. Some particular features inherent to the TiO 2 /electrolyte system are discussed.
Proof-of-Concept Prototype Test Results of a Superconducting Fault Current Limiter for Transmission-Level Applications (2005)

SuperPower, Inc. and Nexans SuperConductors GmbH have partnered to develop a superconducting fault current limiter for transmission level applications. The device employs SuperPower's Matrix Fault Current Limiter (MFCL) technology and BSCCO-2212 bulk material manufactured by Nexans' melt cast processing technique. The development program has been underway since June 2002 and is divided into a series of prototype demonstrations of progressive capability, culminating in a Beta prototype that will be installed at a host utility on a 138 kV line. This paper describes the test results of the first major program milestone, a proof-of-concept prototype at distribution level voltage. The test results show the expected current limiting performance of the MFCL technology to provide fast current limiting and dynamic resistance development before the first peak of the fault. The fault current evenly distributes among the elements of the MFCL array, which employs a resistive-inductive approach for limiting the current. The results also show the excellent electric field performance of the BSCCO-2212 material.
Histology and Cytochemistry of Human Skin (1969)

The outer surface of the palpebrae has an evenly distributed population of very small vellus hair follicles and eccrine sweat glands, more numerous on the temporal than on the nasal side. The undersurface of the thick epidermis of the palpebral shelves is deeply and intricately sculptured; nerves penetrate the epidermis. Cilia grow in imperfect rows of five to six in the upper and three to four in the lower lid. Ciliary follicles are free of arrector muscles and abound in pigment cells throughout their length, including the matrix. The follicles are surrounded by blood vessels and nerves, far in excess of those found in follicles elsewhere. Sebaceous glands (of Zeis) and glands of Moll, which open into the pilary canals of ciliary follicles, are supplied with many cholinesterase-reactive nerves. Meibomian (tarsal) glands have the most abundant supply of cholinesterase-reactive nerves we have found in any gland, cutaneous or otherwise.
Analysis of path loss and delay spread at 900 MHz and 2.1 GHz while entering tunnels (2001)

Some propagation characteristics in tunnel environments at 900 MHz and 2.1 GHz are analyzed. Narrow-band parameters are given in terms of the propagation factor and linear regression slopes. Wide-band analysis is considered by calculating delay spread factors along the communication path. A ray-launching technique has been implemented, using ray optics and the uniform theory of diffraction (UTD). The proposed theoretical model has been validated by comparing the results with measurements obtained by other authors. The particular situation when a mobile antenna crosses the tunnel entrance and transmitter is outside the tunnel is studied. Our simulations show that the larger the angular separation of the transmitter with respect to the tunnel longitudinal axis is, the higher values of the delay spread. The more critical point appears around the tunnel entrance ("excitation zone"), where a signal power decay up to 40 dB may be detected. A similar value has been already found when turning a corner in microcellular urban environments.
MELAS syndrome (1988)

Severe prolonged migrainous symptoms and prolonged partial status epilepticus are characteristic features of the MELAS syndrome (mitochondrial encephalomyopathy, lactic acidosis, and stroke-like episodes). Maternal transmission previously found in myoclonus epilepsy and ragged-red fibers (MERRF), another mitochondrial disease, is suggested in this disorder as well.
Efficient Decomposition of Assigned Sequential Machines and Boolean Functions for PLD Implementations (1995)

Programmable devices impose hard constraints on the size of circuits that can be implemented with them or with their blocks. Therefore, decompositional implementation of large functions is not a choice but a real necessity in this case. The objective of the new decomposition method presented in rhis paper is to implement a complex Boolean function or an assigned sequential machine with a minimal number of constrained building bIocks and minimal connections between the blocks. The method aims in solving problems with hard constraints in multiple dimensions. It differs substantially from the methods for solving similar simpler one-dimensional problems. The method is vtvy general and, after some small changes. ir can be appIr'ed to many other partitioning problems. The experimentanl results show that the method is very efficient.
Creating multilingual translation lexicons with regional variations using web corpora (2004)

The purpose of this paper is to automatically create multilingual translation lexicons with regional variations. We propose a transitive translation approach to determine translation variations across languages that have insufficient corpora for translation via the mining of bilingual search-result pages and clues of geographic information obtained from Web search engines. The experimental results have shown the feasibility of the proposed approach in efficiently generating translation equivalents of various terms not covered by general translation dictionaries. It also revealed that the created translation lexicons can reflect different cultural aspects across regions such as Taiwan, Hong Kong and mainland China.
ON THE PERIODS OF THE FIBONACCI SEQUENCE MODULO M (1989)

In the last few years I had some occasions to guide activities in a mathematics-with-computer club for 15-year-olds, where we investigated the function K(m) . Theorems 1 and 2 of the present article were found (without proofs) by members of these clubs. To be more specific, these are those of the students results, which I was not able to find in the literature either before or after they have emerged in the club. The rest of the students discoveries can be found either in [1] or in [4]. One of these is the following lemma which was suggested by the student Oded Farago.
Improved apparatus for thermophysical measurements on liquid metals up to 8000 K (1976)

An apparatus is described for making thermophysical measurements on liquid metals up to 0.4 GPa and 8000 K. Metal samples are resistively heated on a submillisecond time scale along an isobar. Techniques for measuring enthalpy, specific volume, electrical resistivity, and temperature are discussed with a critical evaluation of the accuracy and limitations of each measurement.
Straws in the Wind: The 1979 Vote of No Confidence (1989)

Mrs Shirley Williams, in her emotional but considered letter of resignation from the National Executive Committee of the Labour Party, summed up the feelings of the Labour defectors when she wrote in February 1981: ‘The party I loved and worked for over so many years, no longer exists … it is not the democratic socialist party that I joined.’1 It was this negative feeling which best expressed the case for the creation of a new party. Moderates had become so heartily disillusioned with the Labour Party that they no longer felt they could work within it to achieve effective change — and still less win parliamentary power. Such cries of disaffection from within had, of course, been a periodic occurrence in the fractious history of the Labour Party. Since its bold inception, the party had been split, as we have noted, between its belief in socialism and belief in social democratic principles. Indeed, was it a party of trade-unionism and really little more? It was created from an improbable partnership between stolid working-class trade-unionists and idealistic middleclass intellectuals. It has never since decided ‘whether it is a party of gradual reform in the Liberal and social democratic tradition or of red-hot, full-blooded socialism’.2 As David Marquand explained, the liberal element in the Labour Party had given the party a reason for its existence:
Vacunas contra el virus del síndrome reproductivo y respiratorio porcino (PRRSV): escribiendo una historia (2010)

"The porcine reproductive and respiratory syndrome virus (PRRSV) constitutes one of the most serious problems of the pig industry in the world. It affects pigs of all ages and causes reproductive and respiratory disorders that create great economic losses. These increase due to the rapid spread of the disease and the inefficiency of the commercial vaccines. Modified live and killed vaccines are the two types of commercial vaccines currently available on the market for American and European strains. Although these vaccines can reduce disease symptoms and viremia, they do not prevent infection in any way and cross-presentation is variable against heterologous virus. Furthermore, it has been reported that the vaccine's virus can spread to other susceptible animals. For these reason, many studies focused on the development of new vaccines that include different vectors for the development of DNA vaccines by evaluating various structural proteins. The use of PRRSV infectious clones, as well as the construction of viral chimeras between the vaccine virus and highly infectious virus have also been evaluated. All these strategies have failed to develop an effective vaccine against PRRSV; therefore it remains as a major challenge."

En el marco constitucional e internacional, vigente en Espana, una posible reforma de la Ley de Libertad Religiosa debe garantizar la efectividad del derecho de libertad religiosa y de conciencia en los terminos mas amplios posibles y arbitrar las medidas necesarias para su eficaz proteccion.
Network Management in Cloud Computing for Public Administration: A Practical Use Case (2014)

Network management is one of the crucial aspects to take into account when designing a Cloud platform for Infrastructure as a Service providers. It represents one of the main obstacles to the adoption of external Cloud services by the Public Administrations. In this work, we present our solution to create a Cloud infrastructure within the PRISMA project, with the goal to fulfill the requirements of an external Entity. More specifically, we approached the issue of managing different network domains dynamically, including Virtual Private Network services and Port forwarding. The final result is a very flexible system that enables us to cope with all the principal scenarios that may take place.
