A Survey of AoIM, Distribution and Communication in Peer-To-Peer Online Games (2012)

In this paper we discuss the issues relating to architecture formation in MMOGs and the two principal design choices that must be made when constructing a Peer-to-Peer (P2P) MMOG: the Area of Interest Management (AoIM) scheme and the distribution and communication mechanism. We introduce an updated survey of the state-of-the-art of AoIM in P2P Online Games. We identify key issues in the development and deployment of such architectures. We analyze the main features of existing solutions. The contribution of the paper is a novel perspective in understanding the limitations of existing solutions and discussing the design criteria for an alternative P2P approach to alleviate scalability issues.
Porphyrins bearing halogens at the meso-phenyl and b-pyrrolic ‡ positions: synthesis and spectral properties § (1996)

Summary — The synthesis of symmetrical porphyrins chlorinated at both ortho positions of the meso-aryl substituents, and the chlorination and bromination of the b-pyrrole positions is reported. The /3-chlorination of meso-tetraphenylporphyrin via its nickel(II) complex is also described. In addition, we communicate the first perchlorination of tetramesitylporphyrin, where halogen substitution occurred at the b-pyrrolic positions as well as at both the vacant meta positions of the trimethylphenyl groups. The iron complexes of these various poly halogen ated porphyrins are also described, since they are robust and efficient catalysts in oxidation reactions.
Quantum-state transfer in imperfect artificial spin networks (2005)

High-fidelity quantum computation and quantum state transfer are possible in short spin chains. We exploit a system based on a dispersive qubit-boson interaction to mimic XY coupling. In this model, the usually assumed nearest-neighbor coupling is no longer valid: all the qubits are mutually coupled. We analyze the performances of our model for quantum state transfer showing how preengineered coupling rates allow for nearly optimal state transfer. We address a setup of superconducting qubits coupled to a microstrip cavity in which our analysis may be applied.
Laser-micromachined Fabry-Perot optical fiber tip sensor for high-resolution temperature-independent measurement of refractive index (2008)

We propose and demonstrate a Fabry-Perot (F-P) optical fiber tip sensor for high-resolution refractive-index measurement fabricated by using 157-nm laser micromachining, for the first time to our knowledge. The sensor head consists of a short air F-P cavity near the tip of a single-mode fiber and the fiber tip. The external refractive index is determined according to the maximum fringe contrast of the interference fringes in the reflective spectrum of the sensor. Such a sensor can provide temperature-independent measurement of practically any refractive index larger than that of air and offers a refractive-index resolution of ~4 x 10(-5) in its linear operating range. The experimental data agree well with the theoretical results.
Imaging moving targets through scattering media (2017)

Optical microscopy in complex, inhomogeneous media is challenging due to the presence of multiply scattered light that limits the depths at which diffraction-limited resolution can be achieved. One way to circumvent the degradation in resolution is to use speckle- correlation-based imaging (SCI) techniques, which permit imaging of objects inside scattering media at diffraction-limited resolution. However, SCI methods are currently limited to imaging sparsely tagged objects in a dark-field scenario. In this work, we demonstrate the ability to image hidden, moving objects in a bright-field scenario. By using a deterministic phase modulator to generate a spatially incoherent light source, the background contribution can be kept constant between acquisitions and subtracted out. In this way, the signal arising from the object can be isolated, and the object can be reconstructed with high fidelity. With the ability to effectively isolate the object signal, our work is not limited to imaging bright objects in the dark-field case, but also works in bright-field scenarios, with non-emitting objects.
Proyecto Anaco-U.C.V. estudio epidemiológico sobre la pérdida prematura del primer molar permanente en niños con edades comprendidas entre 6 y 10 años (2001)

espanolEl convenio U.C.V.- Corpoamigos Anaco es uno de los seminarios del Programa de Extension Docencia- Servicio de la Facultad de Odontologia que se viene realizando en 16 estados del pais. Dicho seminario cuenta con los recursos humanos, materiales y financieros necesarios para una optima atencion a la comunidad, por lo cual es considerado uno de los seminarios mas importantes de la Facultad de Odontologia de la U.C.V. (fig. 1) En el siguiente estudio de investigacion se tomaron 142 pacientes de ambos sexos con edades comprendidas entre 6 y 10 anos (con la perdida de alguno de los primeros molares). Los resultados obtenidos muestran una alta prevalencia de la perdida de este molar, lo que nos lleva a enfrentar la gran problematica presente en las poblaciones rurales por la perdida del primer molar a temprana edad, cuya situacion se agrava por la falta de programas preventivos en dichas regiones. Es importante hacer notar la inexistencia de investigaciones epidemiologicas de este tema en poblaciones rurales como la de Anaco. EnglishThe treaty between U.C.V.- Corpoamigos Anaco is one of the seminars of extension teaching service program of the Odontology Faculty that is being developed in 16 states around the country. This seminar consists of human, material and financial resources needed to get the best attention for the community. That´s what makes this seminar one of the most important of the Odontology Faculty of the U.C.V.(fig.1) In the research that has been done the sample was conformed by 142 pacients, males and females with ages between 6 and 10 (with the lost of at least one of the first molars). The results obtained showed a high frequency of the losing of this molar, what becomes to be a big problem in the rural population. This problem gets worse because there are not enough preventive programs in these comunities. It is very important to notice that in Venezuela (including the rural community of Anaco) there are not epidemiological research about this case.
UHF RFID localization system based on a phased array antenna (2011)

This paper presents new experimental results of angle of arrival (AoA) measurements for localizing passive RFID tags in the UHF frequency range. The localization system is based on the principle of a phased array with electronic beam steering mechanism. This approach has been successfully applied within a UHF RFID system and it allows the precise determination of the angle and the position of small passive RFID tags. The paper explains the basic principle, the experimental setup with the phased array and shows results of the measurements.
New Diphosphite Ligands for Catalytic Asymmetric Hydrogenation: The Crucial Role of Conformationally Enantiomeric Diols (1999)

Efficient catalysis of asymmetric hydrogenations is possible with complexes of the type 1 which contain chiral diphosphites as ligands. Thus the Rh-catalyzed hydrogenation of dimethyl itaconate with a catalyst containing 1,4:3,6-dianhydro-D-mannite and conformationally enantiomeric diols is highly enantioselective.
Registration and fusion of retinal images-an evaluation study (2003)

We present the results of a study on the application of registration and pixel-level fusion techniques to retinal images. The images are of different modalities (color, fluorescein angiogram), different resolutions, and taken at different times (from a few minutes during an angiography examination to several years between two examinations). We propose a new registration method based on global point mapping with blood vessel bifurcations as control points and a search for control point matches that uses local structural information of the retinal network. Three transformation types (similarity, affine, and second-order polynomial) are evaluated on each image pair. Fourteen pixel-level fusion techniques have been tested and classified according to their qualitative and quantitative performance. Four quantitative fusion performance criteria are used to evaluate the gain obtained with the grayscale fusion.
A 20 ns, low power, NMOS 1Kx4 static RAM (1981)

Using scaled NMOS processing and novel circuit design techniques to enhance the speed-power product, a high-speed, low power, fully static 1024-word/spl times/4-bit random access memory has been developed. Applications related requirements such as fast chip select access time and /spl times/4 organization for cache and microcode store memories are central to the device definition. Highly producible 4.5 /spl mu/m design rules with 2.5 /spl mu/m polysilicon gate lengths are incorporated in addition to depletion load transistors in the memory array. The resulting TTL-compatible, 5 V only 1K/spl times/4 static RAM achieves a typical address access time of 20 ns and a chip select access time of 5 ns with power dissipation under 350 mW.
The Association of a Polydioxanone Tent Without a Guided Tissue Regeneration Membrane to a Coronal Sliding Flap for Root Coverage (2009)

The association of the PDS tent without the GTR membrane to a coronal sliding flap for root coverage of Miller Class I and II gingival recessions allows root coverage, gain of attachment level, and an increase of keratinized mucosa. For root coverage, it is not necessary to use the GTR membrane associated to the PDS tent, thereby reducing surgical costs. Future studies should be conducted to assess the sole performance of the PDS as an alternative method to a connective tissue graft and coronal sliding flap, thus decreasing risks and post-surgery discomfort.
A Long Stroke Electromagnetic $XY$ Positioning Stage for Micro Applications (2011)

In this paper, a Lorentz force-based <formula formulatype="inline" xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"><tex Notation="TeX">$XY$</tex></formula> positioning stage with a stack of four electromagnetic linear motors in parallel configuration is presented. The overall design of the positioning stage consists of a mobile and a fixed part separated using a four-point contact technique. The uniqueness of the proposed positioning stage lies in its light design with the ability to perform variable strokes at short <formula formulatype="inline" xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"><tex Notation="TeX">$(< 100 \mu$</tex></formula> m) and long range (millimeter level) with preembedded auto guidance feature. The analytical modeling and experiment have been realized. The open- and closed-loop performance of positioning stage in linear and nonlinear trajectories have been tested and good agreement is observed between experimental and analytical results. The positioning stage is able to perform variable strokes up till 2 mm in the <formula formulatype="inline" xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"><tex Notation="TeX">$xy$</tex></formula> plane. In closed loop, the maximum precision errors in short and long strokes are found to be 0.031 and 0.451 μm, respectively. The maximum travel speed is 12 mm/s in open loop.
Evolutive ANFIS training for energy load profile forecast for an IEMS in an automated factory (2011)

In this paper an evolutive algorithm is used to train an adaptative-network-based fuzzy inference system (ANFIS), particularly a genetic algorithm (GA). The GA is able to train the antecedent and consequent parameters of an ANFIS, which is used for energy load profile forecasting in an automated factory. This load forecasting is useful to support an intelligent energy management system (IEMS), which enables the user to optimize the energy consumptions by means of getting the optimal work points, scheduling the production according to these points, etc. The proposed training algorithm showed excellent results with complex plants like industrial energy consumers in the user-side, where the randomness of the loads is higher than in utility loads. Real data from an automated car factory were used to test the presented algorithms. Appropriated results were obtained.
Systemic Delivery of Secreted Protein by Grafts of Epidermal Keratinocytes: Prospects for Keratinocyte Gene Therapy (1994)

Grafts of autologous keratinocytes genetically altered to secrete a new gene product are a potential vehicle for gene therapy. To consider the feasibility of such an approach, we have examined the ability of keratinocytes to secrete and deliver apolipoprotein E (apoE) to the circulation of mice bearing grafts of human keratinocytes. The grafted keratinocytes secreted two forms of apoE, an endogenous apoE encoded in the genome and a recombinant apoE encoded in a transfected gene construct. In vitro studies showed that endogenous apoE was secreted from basal keratinocytes whereas recombinant apoE was secreted from basal as well as suprabasal cells. On the basis of amounts of recombinant apoE present in the serum of grafted mice, we estimate that a graft occupying 2% of the surface area of an adult human would deliver 6.5-8.3 mg of recombinant apoE protein per day.
SARS Coronavirus, but Not Human Coronavirus NL63, Utilizes Cathepsin L to Infect ACE2-expressing Cells (2005)

Viruses require specific cellular receptors to infect their target cells. Angiotensin-converting enzyme 2 (ACE2) is a cellular receptor for two divergent coronaviruses, SARS coronavirus (SARS-CoV) and human coronavirus NL63 (HCoV-NL63). In addition to hostcell receptors, lysosomal cysteine proteases are required for productive infection by some viruses. Here we show that SARS-CoV, but not HCoV-NL63, utilizes the enzymatic activity of the cysteine protease cathepsin L to infect ACE2-expressing cells. Inhibitors of cathepsin L blocked infection by SARS-CoV and by a retrovirus pseudotyped with the SARS-CoV spike (S) protein but not infection by HCoV-NL63 or a retrovirus pseudotyped with the HCoV-NL63 S protein. Expression of exogenous cathepsin L substantially enhanced infection mediated by the SARS-CoV S protein and by filovirus GP proteins but not by the HCoV-NL63 S protein or the vesicular stomatitis virus G protein. Finally, an inhibitor of endosomal acidification had substantially less effect on infection mediated by the HCoV-NL63 S protein than on that mediated by the SARS-CoV S protein. Our data indicate that two coronaviruses that utilize a common receptor nonetheless enter cells through distinct mechanisms.
Experimental and numerical investigation of acoustic streaming excited by using a surface acoustic wave device on a 128° YX-LiNbO<sub>3</sub>substrate (2010)

This work uses a finite volume method to investigate three-dimensional acoustic streaming patterns produced by surface acoustic wave (SAW) propagation within microdroplets. A SAW microfluidic interaction has been modelled using a body force acting on elements of the fluid volume within the interaction area between the SAW and fluid. This enables the flow motion to be obtained by solving the laminar incompressible Navier–Stokes equations driven by an effective body force. The velocity of polystyrene particles within droplets during acoustic streaming has been measured and then used to calibrate the amplitudes of the SAW at different RF powers. The numerical prediction of streaming velocities was compared with the experimental results as a function of RF power and a good agreement was observed. This confirmed that the numerical model provides a basic understanding of the nature of 3D SAW/liquid droplet interaction, including SAW mixing and the concentration of particles suspended in water droplets.
Staged program repair with condition synthesis (2015)

We present SPR, a new program repair system that combines staged program repair and condition synthesis. These techniques enable SPR to work productively with a set of parameterized transformation schemas to generate and efficiently search a rich space of program repairs. Together these techniques enable SPR to generate correct repairs for over five times as many defects as previous systems evaluated on the same benchmark set.
Homodyne locking of a squeezer (2009)

We report on the successful implementation of an approach to locking the frequencies of an optical parametric oscillator (OPO)-based squeezed-vacuum source and its driving laser. The technique allows the simultaneous measurement of the phase shifts induced by a cavity, which may be used for the purposes of frequency locking, as well as the simultaneous measurement of the sub-quantum-noise-limited (sub-QNL) phase quadrature output of the OPO. The homodyne locking technique is cheap, easy to implement, and has the distinct advantage that subsequent homodyne measurements are automatically phase locked. The homodyne locking technique is also unique in that it is a sub-QNL frequency discriminator.
Electromagnetic field-induced thermal management of biological materials (2017)

The study of temperature profiles and heat transport within the human body when subjected to electromagnetic waves is crucial for development and improvement of radiofrequency cardiac ablation treatments (radio frequency ablation). The present study provides an analytical solution for computing the temperature profiles for blood and tissue for various biological media along with heat transfer behavior during various ablation processes. The local thermal nonequilibrium model is used to characterize the bioheat transport through the biological medium. The two energy equation model for tissue and blood phase is considered. To understand the effects induced by imposed electromagnetic field, the specific absorption rate of body tissues is also studied. The results obtained have been validated against the pertinent numerical results in the literature. This study provides benchmark analytical solutions for heat transport through biological media, thereby helping in understanding the thermophysiologic response of human body toward imposed electromagnetic radiation.
McDRAM v2: In-Dynamic Random Access Memory Systolic Array Accelerator to Address the Large Model Problem in Deep Neural Networks on the Edge (2020)

The energy efficiency of accelerating hundreds of MB-large deep neural networks (DNNs) in a mobile environment is less than that of a server-class big chip accelerator because of the limited power budget, silicon area, and smaller buffer size of static random access memory associated with mobile systems. To address this challenge and provide powerful computing capability for processing large DNN models in power/resource-limited mobile systems, we propose McDRAM v2, which is a novel in-dynamic random access memory (DRAM) systolic array accelerator architecture. McDRAM v2 makes the best use of large in-DRAM bandwidths for accelerating various DNN applications. It can handle large DNN models without off-chip memory accesses, in a fast and efficient manner, by exposing the large DRAM capacity and large in-DRAM bandwidth directly to an input systolic array of a processing element matrix. Additionally, it maximizes data reuse using a systolic multiply-accumulate (MAC) structure. The proposed architecture maximizes the utilization of large-scale MAC units by judiciously exploiting the DRAM's internal bus and buffer structure. An evaluation of large DNN models in the fields of image classification, natural language processing, and recommendation systems shows that it achieves 1.7 times tera operations per second (TOPS), 3.7 times TOPS/watt, and 8.6 times TOPS/mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> improvements over a state-of-the-art mobile graphics processing unit accelerator, and 4.1 times better energy efficiency over a state-of-the-art server-class accelerator. Moreover, it incurs a minimal overhead, i.e., a 9.7% increase in area, and uses less than 4.4 W of peak operating power.
Magnetic Domain Nucleation and Propagation in Fine Wires (1969)

The effect of material composition and structure on the magnetic domain nucleation field (Hn) and the domain wall propagation field (Hp) in fine cold-drawn Permalloy wires is reported. Binary Ni/Fe wires (Fe&gt;20%) were reentrant (Hn&gt;Hp) when cold drawn to less than 250 μm diam. Alloying additions inhibited stress recovery during drawing and annealing and thereby increased and stabilized Hn. Variations in Hn along the wire length correlated with defects in the wire surface. Sputter coating the wire improved the surface condition and reduced variations in Hn. A magnetostrictive model of re-entrancy is proposed and discussed.
Investigation of the platinum metals: IV. Determination of iridium in platinum alloys by the method of fusion with lead (1923)

A study has been made of the analytical details of the Deville and Stas method for the determination of iridium in platinum alloys containing from o. i to 20 per cent of iridium. Specially prepared alloys made from, highly purified metals were used in the investigation. It was found that the concentration of nitric acid, the concen- tration of aqua regia, the proportion of lead, and the time and the temperature of the lead fusion can be varied over a wide range without affecting the determination.
Attraction of Yellowjackets (<i>Vespula</i>spp.) to Heptyl Butyrate in Washington State (Hymenoptera: Vespidae) (1973)

During 2 years of trapping with artificial attractants in the Pullman, Washington, area, 6 species of Vespula were collected. Two species, V. atropilosa (Sladen) and V. pensylvanica (Saussure), were collected in large numbers. V. atropilosa was more strongly attracted to heptyl butyrate than was V. pensylvanica. Most queens and workers collected in attractant traps were V. atropilosa. Use of artificial attractant traps for controlling yellowjackets is discussed in relation to species composition. The importance of appropriate timing is emphasized and related to the seasonal buildup and decline of worker yellowjacket populations.
Upwind preview to a horizontal axis wind turbine: a wind tunnel and field‐scale study (2015)

Abstract Data collected at the Eolos wind research facility and in the Saint Anthony Falls Laboratory atmospheric boundary layer wind tunnel are used to study the impact of turbulent inflow conditions on the performance of a horizontal axis wind turbine on flat terrain. The Eolos test facility comprises a 2.5MW Clipper Liberty C96 wind turbine, a meteorological tower and a WindCube LiDAR wind profiler. A second set of experiments was completed using particle image velocimetry upwind and in a wake of a miniature turbine in the wind tunnel to complement LiDAR measurements near the Eolos turbine. Joint statistics, most notably temporal cross‐correlations between wind velocity at different heights and turbine performance, are presented and compared at both the laboratory and field scales. The work (i) confirms that the turbine exerts a blockage effect on the mean flow and (ii) suggests a key, specific elevation, above hub height, where the incoming velocity signal is statistically most relevant to turbine operation and control. Wind tunnel measurements confirm such indication and suggest that hub height velocity measurements are optimal for wind preview and/or as input for active control strategies in aligned turbine configurations.

Planning in the Fluent Calculus Using Binary Decision Diagrams (2001)

BDDplan was created to perform certain reasoning processes in the fluent calculus, a flexible framework for reasoning about action and change based on first-order logic with equality (plus some second-order extensions in some cases). The reasoning is done by mapping the problems into propositional logic, which, in turn, can be implemented as operations on binary decision diagrams (BDDs).
