Research Article Opposite roles of protein kinase C isoforms in proliferation, differentiation, apoptosis, and tumorigenicity of human HaCaT keratinocytes (2004)

We have previously shown that the protein ki- nase C (PKC) system plays a pivotal role in regulation of proliferation and differentiation of the human ker- atinocyte line HaCaT which is often used to assess processes of immortalization, transformation, and tu- morigenesis in human skin. In this paper, using pharma- cological and molecular biology approaches, we investi- gated the isoform-specific roles of certain PKC isoen- zymes (conventional cPKCa and b; novel nPKCd and e) in the regulation of various keratinocyte functions.
Optimization of parallel task execution on the adaptive reconfigurable group organized computing system (2002)

This paper presents the architecture organization of a task adaptive reconfigurable high-performance computing system for parallel processing of data-flow tasks. The architecture of this reconfigurable system allows flexible distribution of uniform configurable resources (FPGA-based) between tasks. Each task corresponds to a specific group processor (GP) adapted for the task requirements. The paper discusses the method of selecting the optimal group processor configuration and mapping group processors on the field of configurable resources. The performance results of the first prototype of the ARGO-parallel computing system are presented.
New client puzzle outsourcing techniques for DoS resistance (2004)

We explore new techniques for the use of cryptographic puzzles as a countermeasure to Denial-of-Service (DoS) attacks. We propose simple new techniques that permit the out-sourcing of puzzles; their distribution via a robust external service that we call a bastion. Many servers can rely on puzzles distributed by a single bastion. We show how a bastion, somewhat surprisingly, need not know which servers rely on its services. Indeed, in one of our constructions, a bastion may consist merely of a publicly accessible random data source, rather than a special purpose server. Our out-sourcing techniques help eliminate puzzle distribution as a point of compromise.
An Efficient Method for the Stereoselective Synthesis of 1,2-cis- and 1,2-trans-Ribofuranosides from 1-Hydroxy Ribofuranose by the Use of Diphenyltin Sulfide and Trifluoromethanesulfonic Anhydride (1991)

Abstract 1,2-trans-Ribofuranosides are stereoselectively synthesized in high yields directly from 1-hydroxy ribofuranose and trimethylsilylated nucleophiles by the use of diphenyltin sulfide and trifluoromethanesulfonic anhydride. Even further, in the coexistence of lithium perchlorate, 1,2-cis-ribofuranosides are prepared predominantly in high yields.
Static motor circuit analysis: an introduction to theory and application (2000)

For the purpose of the analysis results presented within this paper an ALL-TEST IV PRO/sup TM/ 2000 motor circuit analyzer (MCA) was selected as it provided resistance to one milli-Ohm, impedance, inductance, phase angle, and a special test that measures current response at measured variable applied frequencies. Test voltage and frequencies were applied at less than 10 V RMS, true sine wave, at applied frequencies from 100 to 800 Hz. The electric motors tested were provided at a number of locations and included either planned failures or failures that were first analyzed then investigated using alternate methods. Histories of MCA were analyzed from data collected over a period of approximately 15 years.
Method for uterine contraction monitoring with passive RFID tags (2017)

Pregnant women in labor, or at risk of premature delivery, are currently connected to cumbersome electronic uterine contraction monitors to assess their contractions. Existing monitors are not only uncomfortable but also prevent the pregnant woman's mobility. In this paper, a method to monitor uterine contractions using passive RFID tags is proposed. Simulations have been completed using experimental data as a starting point to provide proof of concept for implementing a wireless and battery free uterine contraction monitor. Such a monitor can be easily integrated into wearable garments for comfortable continuous monitoring.
Mutual coupling reduction and miniaturization arrays antennas using new structure of EBG (2017)

The microstrip patch antennas are associated with some disadvantages, such as narrow bandwidth and low gain. To meet the demands of long distance communication, is necessary to design antennas with very high gain. The easiest way of gain enhancement can be obtained is from the array models, but the increasing array spacing, the gain of the antenna gets reduced significantly also decreasing array spacing, a strong mutual coupling is appears. This letter describes a novel configuration of mushroom-type EBGs structures 13×2 to reduce mutual coupling between the radiating elements 2×4. Our objective is to reduce both the element separation and the mutual coupling between the patch antennas. The results show that a reduction in mutual coupling from −33.24 dB to −59.36 dB is obtained between elements at the operation frequency 5.8 GHz of the antenna array. The proposed configuration is designed, optimized, and miniaturized by using electromagnetic software CST Microwave Studio.
Lambda Dependency-Based Compositional Semantics (2013)

This short note presents a new formal language, lambda dependency-based compositional semantics (lambda DCS) for representing logical forms in semantic parsing. By eliminating variables and making existential quantification implicit, lambda DCS logical forms are generally more compact than those in lambda calculus.
Double J/ψ production in pion-nucleon scattering at COMPASS (2023)

We present the study of the production of double J/ψ mesons using COMPASS data collected with a 190 GeV/c π− beam scattering off NH3, Al and W targets. Kinematic distributions of the collected double J/ψ events are analysed, and the double J/ψ production cross section is estimated for each of the COMPASS targets. The NH3 results are compared to predictions from single- and double-parton scattering models as well as the pion intrinsic charm and the tetraquark exotic resonance hypotheses. It is demonstrated that the single parton scattering production mechanism gives the dominant contribution that is sufficient to describe the data. An upper limit on the double intrinsic charm content of the pion is evaluated. No significant signatures that could be associated with exotic tetraquarks are found in the double J/ψ mass spectrum.
Intramural Coronary Vasculature Prevents Transmural Radiofrequency Lesion Formation (2003)

Flow through even small intramyocardial vessels can prevent transmural lesion formation and preserve conduction through an RF lesion. These findings may represent an unrecognized obstacle to the creation of linear RF lesions in the clinical setting.
Fabrication of a Bragg beam splitter for hard x-ray free-electron lasers (2013)

We report a fabrication method of an ultrathin silicon crystal as a beam splitter for the hard x-ray regime based on the Bragg diffraction operated in the symmetric Bragg geometry, and evaluation results of crystalline perfection at SPring-8. A sub-10-μm thick Si(511) crystal was fabricated with a reactive dry etching method using atmospheric-pressure plasma. Following the evaluation of topography and diffractometry, the crystal was found to be strain-free, and capable of splitting a monochromatic x-ray beam into two branches with almost 1:1 splitting ratio.

Multilateral TAML Level 4 Junction Provides Maximum Flexibility for Drilling and Intelligent Completions (2012)

Abstract A multilateral (MLT) well with an advanced intelligent completion string was recently completed in the Middle East. The well was designed as a "stacked" dual producer in the upper and lower reservoir, and was drilled using the latest geo-steering techniques to accurately place the wellbore in a highly faulted and geologically complex structure. Rotary-steerable drilling systems (RSS) were used in several of the hole sections, along with advanced logging-while-drilling (LWD) tools including multi-pole acoustic, azimuthal deep resistivity, and resistivity at bit. Encounters with unstable shale and faults made the drilling difficult, but the decisions made in real-time to navigate the well resulted in a very high percentage of net pay in both laterals. This well combined TAML Level 4 multilateral (MLT) technology with passive inflow control devices in the laterals and an advanced intelligent completion system in the mainbore. The TAML Level 4 multilateral junction was cemented to isolate unstable shale above the reservoir and to provide zonal isolation from the lateral completions, which were compartmentalized into stages with proprietary swellable packers and inflow control devices (ICDs). The intelligent completion was run in the mainbore with two interval control valves (ICVs) and isolation ball valve (LV ICV) to manage the production from each of the two laterals independently. The ICVs and LV ICV are controlled hydraulically through four control lines to surface, which were run in a flat-pack with one electric line to control a downhole gauge package for each lateral. Finally, the well was configured to allow the installation of a large electric submersible pump (ESP) to be run inside the upper 9-5/8-in. production tubing. This project required intensive planning and coordination for more than a year in advance, which made the project successful despite the difficult drilling conditions and resulted in very little NPT for wellbore construction operations. This paper will focus on the planning, execution and lessons learned from the project.
Belief propagation based MIMO detection operating on quantized channel output (2010)

In multiple-antenna communications, as bandwidth and modulation order increase, system components must work with demanding tolerances. In particular, high resolution and high sampling rate analog-to-digital converters (ADCs) are often prohibitively challenging to design. Therefore ADCs for such applications should be low-resolution. This paper provides new insights into the problem of optimal signal detection based on quantized received signals for multiple-input multiple-output (MIMO) channels. It capitalizes on previous works which extensively analyzed the unquantized linear vector channel using graphical inference methods. In particular, a “loopy” belief propagation-like (BP) MIMO detection algorithm, operating on quantized data with low complexity, is proposed. In addition, we study the impact of finite receiver resolution in fading channels in the large-system limit by means of a state evolution analysis of the BP algorithm, which refers to the limit where the number of transmit and receive antennas go to infinity with a fixed ratio. Simulations show that the theoretical findings might give accurate results even with moderate number of antennas.
Laser-Driven Waves in a Freely Expanding Gas Jet (1971)

The focused output of a ruby laser has been used to drive waves which travel in the same direction as the laser beam. The density gradient produced by expanding high-pressure air or hydrogen into a vacuum was irradiated by the laser from the vacuum side of the jet. A luminous plasma was observed to propagate up the jet, through the orifice, and into the gas reservoir. Observations of this type have application to the study of comparable waves generated at the surface of a solid. Measurements of the luminous front velocity are reported over the gas density range of 1–7 amagats and laser power range of 100–500 MW. The scaling relations for this front velocity with laser intensity and gas density are derived for many of the interaction models proposed in the literature. Only the gasdynamic model with fluid motions induced during laser heating compares favorably with the data.
When Memories Make a Difference: Multimodal Literacy Narratives for Preservice ELA Methods Students (2020)

This article examines multimodal literacy narrative projects designed by students in a methods of teaching course for secondary preservice English Language Arts teachers. For the multimodal project, preservice teachers infused written, audio, and visual text using a variety of creative mediums. Through combined theoretical frames, the researcher explores semiotics and preservice teachers’ use of multiliteracies as they shift their conceptions of what it means to compose. Finally, this article explores how the act of reflection through the literacy narrative influences preservice teachers’ notions of teaching composition through a variety of mediums.
Ultrasonic imaging using spatio-temporal matched field (STMF) processing-applications to liquid and solid waveguides (2001)

This paper is devoted to imaging defects in liquid and solid ultrasonic waveguides. A new ultrasonic imaging technique, based on the spatio-temporal Green functions computation and cross-correlation, is presented. This technique extends the concept of matched field processing (MFP) used in ocean acoustics. Results of experiments conducted in water and in a solid Duralumin bar show that a strong improvement of the spatial resolution is observed with this MFP.
Mitochondria‐targeted green fluorescent proteins: convenient tools for the study of organelle biogenesis in Saccharomyces cerevisiae (2000)

We describe the construction and characterization of a novel set of plasmids for expression of mitochondria-targeted green fluorescent protein (GFP) in Saccharomyces cerevisiae. The vectors include constructs with strong regulatable and constitutive promoters, four different auxotrophic markers for yeast transformation, and a green (S65T) and a blue-shifted (P4-3) variant of GFP. Mitochondria are brightly fluorescent in living yeast cells grown on different carbon sources and at different temperatures, with virtually no background staining. Specific staining of mitochondria is also shown for a respiratory-deficient mutant with abnormal mitochondrial morphology. The plasmids facilitate convenient analysis of mutants defective in mitochondrial morphology or inheritance and, at the same time, are suitable vectors for easy construction of different kinds of GFP fusion proteins to study various aspects of organelle biogenesis in living yeast cells.

Dynamic Modeling of a Spot-welded Car Body Component (1994)

The aim of this work was to determine the optimal dynamic modeling criteria for molded components assembled with spot welding. To allow complete modeling successive of the car body, the FE model of the components must not be overly complex and, in addition, the degree of complexity added by the weld modeling must be minimized to the utmost. A car body component (the fore crossbeam) comprising two welded subcomponents was analyzed. The various types of modeling for each subcomponent and the assembled component were validated in step-by-step by experimentation on actual structures. The welding spots were modeled using constraint equations between the nodes of the connected subcomponents. Several attempts were made to position and distribute the connecting systems. The results. which provide excellent numerical experimental correlation, can be of considerable aid in determining generalized modeling criteria for components of this type.
Selective photoinduced charge separation in perylenediimide-pillar[5]arene rotaxanes (2022)

The ability to control photoinduced charge transfer within molecules represents a major challenge requiring precise control of the relative positioning and orientation of donor and acceptor groups. Here we show that such photoinduced charge transfer processes within homo- and hetero-rotaxanes can be controlled through organisation of the components of the mechanically interlocked molecules, introducing alternative pathways for electron donation. Specifically, studies of two rotaxanes are described: a homo[3]rotaxane, built from a perylenediimide diimidazolium rod that threads two pillar[5]arene macrocycles, and a hetero[4]rotaxane in which an additional bis(1,5-naphtho)-38-crown-10 (BN38C10) macrocycle encircles the central perylenediimide. The two rotaxanes are characterised by a combination of techniques including electron diffraction crystallography in the case of the hetero[4]rotaxane. Cyclic voltammetry, spectroelectrochemistry, and EPR spectroscopy are employed to establish the behaviour of the redox states of both rotaxanes and these data are used to inform photophysical studies using time-resolved infra-red (TRIR) and transient absorption (TA) spectroscopies. The latter studies illustrate the formation of a symmetry-breaking charge-separated state in the case of the homo[3]rotaxane in which charge transfer between the pillar[5]arene and perylenediimide is observed involving only one of the two macrocyclic components. In the case of the hetero[4]rotaxane charge separation is observed involving only the BN38C10 macrocycle and the perylenediimide leaving the pillar[5]arene components unperturbed.
Blinded Fault Resistant Exponentiation. (2006)

As the core operation of many public key cryptosystems, group exponentiation is central to cryptography. Attacks on its implementation in embedded device setting is hence of great concern. Recently, implementations resisting both simple side-channel analysis and fault attacks were proposed. In this paper, we go further and present an algorithm that also inherently thwarts differential side-channel attacks in finite abelian groups with only limited time and storage overhead.
Recycling of spent hydroprocessing catalysts: EURECAT technology (1993)

Abstract Disposal of spent catalysts is a growing concern for all refiners. Environmental regulations are becoming stricter and State recommendations are to develop disposal routes which would emphasize recycling as much as possible, and processing the wastes as near as possible to the production center. In this context, EURECAT has developed a recycling process for the hydroprocessing catalysts used in the oil refineries (NiMo, CoMo, NiW on alumina or mixed alumina silica). The process starts with a regeneration of the catalyst to eliminate hydrocarbons, carbon and sulfur. After a caustic roasting, the material is leached to obtain a solution containing mainly molydenum (or tungsten) and vanadium and a solid containing essentially alumina, cobalt and/or nickel. Molydenum and vanadium are separated by an ion exchange resin technique. The solid is processed in an arc furnace to separate the alumina. Nickel and cobalt are separated by conventional solvent extraction to obtain pure metal. Alumina is disposed of as an inert slag. The strength of the process lies in the combination of proven technologies applied by companies whose reliability in their respective field is well known. The aspects concerning spent catalyst handling, packaging and transport are also discussed.
Independent control of function and chromatic dispersion in diffractive optical devices with metasurfaces (Conference Presentation) (2017)

Diffractive optical devices have many applications in various fields of optics. A fundamental property of all diffractive devices is their negative chromatic dispersion: a diffractive grating always disperses light in the opposite order compared to a refractive prism made of a material with positive (normal) dispersion. Unlike refractive devices, chromatic dispersion in diffractive devices stems from geometrical features, and cannot be controlled via the intrinsic material dispersion. In addition to the always negative sign, the amplitude of diffractive chromatic dispersion is set only by the function of the device. For instance, the angular dispersion of a grating is always given by dθ/dλ=tan⁡(θ)/λ (where θ is the deflection angle and λ is wavelength), or the focal distance dispersion of a diffractive lens is given by df/dλ=-f/λ. Therefore, the chromatic dispersion of diffractive devices has always been set by their function (e.g. by the deflection angle for a grating or the focal distance for a lens), and could not be controlled separately. Here, we present our work on breaking this fundamental relation between the function and chromatic dispersion of diffractive devices using metasurfaces providing independent control over phase and group delays. We use a reflective dielectric metasurface to experimentally demonstrate gratings and lenses that have positive, zero, and extraordinary negative chromatic dispersion. Apart from its fundamental scientific value, this concept expands the applications of diffractive devices as it enables various types of chromatic dispersions. For instance, a special case would be a dispersionless lens operating over a wide bandwidth with the same focal distance.
Improved Light Incoupling in Planar Solar Cells via Improved Texture Morphology of PDMS Scattering Layer (2017)

Planar surfaces on the sunward-facing side of solar cells and modules are undesirable because they incur high front-surface reflectance losses and provide poor light trapping. Several emerging and established solar cell technologies, such as perovskite cells, thin-film cells, epitaxial cells, and tandems that include these, have planar surfaces at their front due to restrictions imposed by the fabrication methods employed. Scattering layers made with polydimethylsiloxane (PDMS) are effective in reducing front-surface reflectance when applied to the front of these cells, but show little light trapping enhancement. In this contribution, we use optical simulations to show that tuning the base angle of random pyramids imprinted in the PDMS layer can improve coupling of light into a planar solar cell. A pyramid base angle of 46° gives the highest short-circuit current density.
New insights into the expanding complexity of the tumor suppressor ASPP2 (2009)

Apoptosis Stimulating Protein of p53-2, ASPP2, aka 53BP2L, (encoded by TP53BP2) is a pro-apoptotic member of a family of p53 binding proteins. ASPP2 expression is frequently suppressed in human cancers and numerous studies have consistently demonstrated that ASPP2 inhibits cell growth as well as stimulates apoptosis-at least in part through a p53-mediated pathway. Two independent mouse models have shown that ASPP2 is a haplo-insufficient tumor suppressor and underscore the importance of the role of ASPP2 in human cancer. However, mounting evidence suggests that the mechanism(s) of action for ASPP2 are complex and likely extend beyond stimulation of apoptotic programs. Data highlighting this expanding spectrum of potential ASPP2-mediated pathways is summarized along with new results from recent in vivo models suggesting new avenues for investigation.

A Internet das coisas (IoT) desempenha um papel fundamental no futuro da Internet, pois integrara bilhoes de dispositivos inteligentes que apresentarao capacidades de deteccao, atuacao e processamento de dados. Assim, cada dispositivo integrado pode ter um ou mais sensores incorporados que potencialmente gerarao enormes quantidades de dados. Este cenario levanta o desafio de eficientemente procurar e selecionar os sensores mais adequados dentro de um conjunto que possa apresentar funcionalidades e recursos similares. Neste contexto, este trabalho apresenta um modelo matematico para selecao de sensores capaz de maximizar o atendimento aos requisitos de entrada do usuario, como precisao, robustez e disponibilidade para diferentes tipos de sensores (como temperatura, pressao, umidade, velocidade do vento) em um orcamento limitado. Este modelo foi testado atraves de dois algoritmos, sendo o primeiro um algoritmo de otimizacao e o segundo uma heuristica gulosa. Estas solucoes foram avaliadas e comparadas em termos de tres criterios: o tempo de otimizacao, a quantidade de orcamento a ser utilizada e limites do objetivo otimo.
