Extending The Lossy Spring-Loaded Inverted Pendulum Model with a\n Slider-Crank Mechanism (2015)

Spring Loaded Inverted Pendulum (SLIP) model has a long history in describing\nrunning behavior in animals and humans as well as has been used as a design\nbasis for robots capable of dynamic locomotion. Anchoring the SLIP for lossy\nphysical systems resulted in newer models which are extended versions of\noriginal SLIP with viscous damping in the leg. However, such lossy models\nrequire an additional mechanism for pumping energy to the system to control the\nlocomotion and to reach a limit-cycle. Some studies solved this problem by\nadding an actively controllable torque actuation at the hip joint and this\nactuation has been successively used in many robotic platforms, such as the\npopular RHex robot. However, hip torque actuation produces forces on the COM\ndominantly at forward direction with respect to ground, making height control\nchallenging especially at slow speeds. The situation becomes more severe when\nthe horizontal speed of the robot reaches zero, i.e. steady hoping without\nmoving in horizontal direction, and the system reaches to singularity in which\nvertical degrees of freedom is completely lost. To this end, we propose an\nextension of the lossy SLIP model with a slider-crank mechanism, SLIP- SCM,\nthat can generate a stable limit-cycle when the body is constrained to vertical\ndirection. We propose an approximate analytical solution to the nonlinear\nsystem dynamics of SLIP- SCM model to characterize its behavior during the\nlocomotion. Finally, we perform a fixed-point stability analysis on SLIP-SCM\nmodel using our approximate analytical solution and show that proposed model\nexhibits stable behavior in our range of interest.\n
Digital media and entertainment service delivery platform (2005)

The emergence of broadband networks, for mobile and fixed environments, has stimulated the multimedia market for the delivery of enriched digital media and entertainment services. A key problem for institutions attempting to capitalize on these new channels for service delivery is a capability to deploy many multimedia services rapidly and cost effectively. The naïve technique is to deploy such solutions independently as so called point solutions. The strategic approach is the development of an environment that acts as a service delivery platform for a range digital media and entertainment services. We present our reference architecture that enables the delivery of multiple digital media and entertainment services in fixed and mobile broadband networked environments. This may be for a telecom operator or a virtual network operator. A fundamental characteristic of our architecture is the capability to deliver multiple services with observed reductions in elapsed effort to bring these services online; with a concomitant reduction in cost and speed to market. The architecture is based upon several experiences globally, is refined further here, and presented as a blueprint.
Morphological Evolution of Polyoctenamer upon Photo‐Ageing (2003)

Abstract The morphological structure evolutions of polyoctenamer upon photo‐ageing have been monitored with the aim of correlating the changes of the microstructure with our previous results concerning chemical and molecular evolutions. The influence of the experimental temperature of photo‐oxidation has been investigated with regard to the melting temperature of the different crystalline microphases. A critical point was clearly exhibited (10 h of UV exposure at 35 °C). Before this point the degradation occurs according an oxidative process and takes place only in the amorphous phases. During this period, the molecular structure changes to induce rapid cross‐linking. After the critical point, the chemical oxidation results from a photolytic process. The extent of the tridimensional network becomes invariant and imperfect crystalline zones are then affected.

Assessing Prinary School; Second Cycle Social Science Textbooks in Amhara Region for Adequate Reflection of Multiculturalism (2011)

Purpose: The main purpose of this study was to evaluate the Amhara region’s second cycle primary level social science textbooks vis-a-vis the principles of multiculturalism. The study investigates the integration of various cultural practices and absence of biases, stereotyping and stereotyped roles. Method: Content analysis was used as the main method of research. The social science textbooks were taken as data sources purposefully. It is because social studies education, like all forms of education, is not neutral. Social studies education necessarily incorporates social issues, social criticisms, and efforts to improve society. It is most directly concerned with such topics as race, racism and racial inequalities, and other issues of social justice like sexism, gender bias and class (Jay, 2003).The data were collected using check list instrument. Results: The major results of this study revealed that the Amhara region’s second cycle primary level social science textbooks reflected multiculturalism. That is, the textbooks have included the cultural heritages of various ethnic, religion, residence, heritages, gender, economic and occupational role. However, biases and stereotyping and stereotyped roles in the selected variables were identified. Biases were disclosed in gender, economic and occupational roles. Conclusion: Except some stereotyped role assignments across gender, the primary school second cycle social science textbooks reflect multiculturalism.

The ReFuGe 2020 Consortium—using “omics” approaches to explore the adaptability and resilience of coral holobionts to environmental change (2015)

Human-induced environmental changes have been linked directly with loss of biodiversity. Coral reefs, which have been severely impacted by anthropogenic activities over the last few decades, exemplify this global problem and provide an opportunity to develop research addressing key knowledge gaps through ‘omics’-based approaches. While many stressors, e.g. global warming, ocean acidification, overfishing and coastal development have been identified, there is an urgent need to understand how corals function at a basic level in order to conceive strategies for mitigating future reef loss. In this regard, availability of fully sequenced genomes has been immensely valuable in providing answers to questions of organismal biology. Given that corals are metaorganisms comprised of the coral animal host, its intracellular photosynthetic algae, and associated microbiota (i.e. bacteria, archaea, fungi, viruses), these efforts must focus on entire coral holobionts. The Reef Future Genomics 2020 (ReFuGe 2020) consortium has formed to sequence hologenomes of ten coral species representing different physiological or functional groups to provide foundation data for coral reef adaptation research that is freely available to the research community.
Cellular Uptake of Chloroquine Is Dependent on Binding to Ferriprotoporphyrin IX and Is Independent of NHE Activity in Plasmodium falciparum (1999)

Here we provide definitive evidence that chloroquine (CQ) uptake in Plasmodium falciparum is determined by binding to ferriprotoporphyrin IX (FPIX). Specific proteinase inhibitors that block the degradation of hemoglobin and stop the generation of FPIX also inhibit CQ uptake. Food vacuole enzymes can generate cell-free binding, using human hemoglobin as a substrate. This binding accounts for CQ uptake into intact cells and is subject to identical inhibitor specificity. Inhibition of CQ uptake by amiloride derivatives occurs because of inhibition of CQ-FPIX binding rather than inhibition of the Na+/H+ exchanger (NHE). Inhibition of parasite NHE using a sodium-free medium does not inhibit CQ uptake nor does it alter the ability of amilorides to inhibit uptake. CQ resistance is characterized by a reduced affinity of CQ-FPIX binding that is reversible by verapamil. Diverse compounds that are known to disrupt lysosomal pH can mimic the verapamil effect. These effects are seen in sodium-free medium and are not due to stimulation of the NHE. We propose that these compounds increase CQ accumulation and overcome CQ resistance by increasing the pH of lysosomes and endosomes, thereby causing an increased affinity of binding of CQ to FPIX.

Synthesis, structure elucidation and redox properties of 99Tc complexes of lacunary Wells Dawson polyoxometalates: insights into molecular 99Tc - metal oxide interactions (2011)

The isotope 99Tc (beta max: 250 keV, half-life: 2 x 105 year) is an abundant product of uranium-235 fission in nuclear reactors and is present throughout the radioactive waste stored in underground tanks at Hanford and Savannah River. Understanding and controlling the extensive redox chemistry of 99Tc is important to identify tunable strategies to separate 99Tc from spent fuel and from waste tanks and once separated, to identify and develop an appropriately stable waste-form for 99Tc. Polyoxometalates (POMs), nanometer sized models for metal oxide solid-state materials, are used in this study to provide a molecular level understanding of the speciation and redox chemistry of incorporated 99Tc. In this study, 99Tc complexes of the (alpha 2-P2W17O61)10- and (alpha 1-P2W17O61)10- isomers were prepared. Ethylene glycol was used as a "transfer ligand" to minimize the formation of TcO2 cdot xH2O. The solution structures, formulations, and purity of TcVO(alpha 1/alpha 2-P2W17O61)7- were determined by multinuclear NMR. X-ray Absorption Spectroscopy of the complexes are in agreement with the formulation and structures determined from 31P and 183W NMR. Preliminary electrochemistry results are consistent with the EXAFS results, showing a facile reduction of the TcVO(alpha 1-P2W17O61)7- species compared to the TcVO(alpha 2-P2W17O61)7- analog. The alpha1- defect is unique in that a basic oxygen atom is positioned toward the alpha1- site and the TcVO center appears to form a dative metal-metal bond with a framework W site. These attributes may lead to the assistance of protonation events that facilitate reduction. Electrochemistry comparison shows that the ReV analogs are about 200 mV more difficult to reduce in accordance with periodic trends.
Superconducting plasmonics and extraordinary transmission (2010)

Negative dielectric constant and dominant kinetic resistance make superconductors intriguing plasmonic media. Here we report on the first study of one of the most important and disputed manifestations of plasmonics, the effect of extraordinary transmission through an array of subwavelength holes, using a perforated film of high-temperature superconductor. We show that in the millimetric wave part of the spectrum exceptionally strong extraordinary transmission exists in the ideal conductor state, improves in the plasmonic regime of a superconductor, and diminishes in a highly lossy metal.
Role of charge-transfer states in bacterial photosynthesis (1986)

Photon echo, photon-echo excitation, and "hole-burning" data recorded in the 800-990 nm region of Rhodobacter sphaeroides R26 and Rhodopseudomonas viridis reaction centers are reported. The primary process in these reaction centers, following excitation, was found to occur in approximately 25 fsec; the long-wavelength band of the primary electron donor (P) was largely homogeneously broadened. In accordance with our previous explanation of hole-burning and photon-echo measurements on Rb. sphaeroides [Meech, S. R., Hoff, A. J. & Wiersma, D. A. (1985) Chem. Phys. Lett. 121, 287-292], we interpret this as resulting from a dephasing of the excitation in P into a background of strongly coupled charge-transfer states. The previously reported picosecond lifetime of the excited P state is assigned to decay of these strongly mixed states. Further, a coupling between P and an adjacent bacteriochlorophyll was observed. The extent of this coupling and the role of charge-transfer states in the functioning of reaction centers is discussed.

SMART SEMANTIC MIDDLEWARE FOR THE INTERNET OF THINGS (2008)

As ubiquitous systems become increasingly complex, traditional solutions to manage and control them reach their limits and pose a need for self-manageability. Also, heterogeneity of the ubiquitous components, standards, data formats, etc, creates significant obstacles for interoperability in such complex systems. The promising technologies to tackle these problems are the Semantic technologies, for interoperability, and the Agent technologies for management of complex systems. This paper describes our vision of a middleware for the Internet of Things, which will allow creation of self-managed complex systems, in particular industrial ones, consisting of distributed and heterogeneous components of different nature. We also present an analysis of issues to be resolved to realize such a middleware.
Reliability of Planar SKiN Interconnect Technology (2012)

The classical module design is limited in lifetime by solder interfaces and wire bond technology. The elimination of the traditional base plate and the replacement of solder interfaces by a high reliable Ag sinter technology led to the first 100% solder free module. The SKiN technology eliminates the last obstacle to a significant lifetime and reliability improvement: the wire bonds. It additionally replaces the interface to the heat sink by an Ag sinter interconnect and thus allows a very compact and light design of power electronic systems.

Polarization controlled coupling and shaping of surface plasmon polaritons by nanoantenna arrays (2015)

We demonstrate experimentally the use of ordered arrays of nanoantennas for polarization controlled plasmonic beam shaping and excitation. Rod- and cross-shaped nanoantennas are used as local point-like sources of surface plasmon polaritons, and the desired phase of the generated plasmonic beam is set directly through their spatial arrangement. The polarization selectivity of the optical nanoantennas allows us to further control the excitation, enabling the realization of a variety of complex and functional plasmonic beam shaping elements. We demonstrate this concept by generating plasmonic self-accelerating beams, plasmonic bottle beams, and switchable dual-focii plasmonic lenses. The freedom in the design and arrangement of these nanoantennas enables us to specifically tailor and control the shapes, wavelengths, and coupling efficiencies of complex plasmonic beams.

LIGHT DAMAGE IN THE RAT RETINA: EFFECT OF A RADIOPROTECTIVE AGENT (WR‐77913) ON ACUTE ROD OUTER SEGMENT DISK DISRUPTIONS (1991)

Primary events in the course of light induced retinal lesions are still not fully elucidated. Under chronic conditions, lipid peroxidation in the retina and death of photoreceptor cells are observed. The radioprotective agent WR-77913 scavenges singlet oxygen, hydrated electrons and free radicals. WR-77913 was used to protect against acute light induced photoreceptor outer segment membrane disruptions in the rat retina. There was a partial but not complete protection at higher illuminance levels (800 lx for 30 min), whereas threshold lesions (400 lx for 30 min) were almost completely prevented. These observations indicate an involvement of photodynamic reactions in causing acute photoreceptor lesions.
Centralized Multiple Random Access Protocol with Contention Window Adjustment (2007)

In this paper, we propose a new multiple access protocol for the ubiquitous network and analyze its performance in the nonsaturated condition. Based on the concept of equilibrium analysis, we analyze its throughput and the contention window size that maximizes its throughput by constructing a Markov model of terminal state. From this work we introduce an index that uniquely decides throughput regardless of the number of terminals or the offered traffic and propose a contention window adjustment algorithm based on the index. Computer simulations that compare the proposed protocol to conventional protocols clarify that the former has superior throughput.
