Reduction of resolution for binary images by an octal grid graph representation model (2013)

We deal with a data structure which is suitable for expression of the binary images. In general, binary images are expressed in raster data or rectangular dissections. In this paper, we describe that it is possible to reduce effectively the number of nodes in raster data represented by “octgrid” which is a type of octal grid graphs to handle heterogeneous rectangular dissections. Precisely, we propose algorithms to reduce the resolution of binary images represented by “octgrid”. Furthermore, we compare by examples our method with the Hilbert scanning, and show that our method reduces the rectangular number by less than 50% than the Hilbert scanning does, in several examples.

Feature-Aided Tracking for Marine Mammal Detection and Classification (2008)

This paper presents a method to detect and classify odontocete echolocation clicks as well as to estimate the number of animals that are vocalizing.A transient detector using the Page test [1][2][3] is used to extract the clicks: the click time, the click duration, the click amplitude and the spectral information of the clicks are extracted.A probability distribution over the species is assigned to each click, based on the spectral information of the click.The estimation of the number of animals is done using feature-aided multi hypothesis tracking (MHT) algorithms.The association is based on the assumptions of slowly-varying click amplitude and intra-click timing [4][5].This work has been done on the dataset provided by the organizers of the 3rd International Workshop on the Detection and Classification o f Marine Mammals using Passive Acoustics, Boston, July 2007.This dataset consists of training and test data; the training data includes vocalizations of three species: Blainville's beaked whale (Mesoplodon densirostris), Risso's dolphin (Grampus griseus) and short-finned pilot whale (Globicephala macrorhynchus).s o m m a i r e Cet article prsente une mthode de dtection et classification de clics d 'cholocation d 'odontoctes ainsi que d'estimation du nombre d 'animaux vocalisant en mme temps.Un dtecteur de transitoires utilisant le test de Page [1-3] permet d 'extraire les clics : leurs instants, dures et amplitudes ainsi que leurs spectres sont stocks.L 'analyse du spectre d 'un clic permet de lui affecter une probabilit de distribution parmi les diffrentes espces.L 'estimation du nombre d 'animaux se fait l'aide d 'un algorithme de tracking (multi hypothesis tracking MHT).L 'association des clics est base sur l'hypothse que l 'amplitude et l'intervalle entre deux clics varient lentement en fonction du temps.Ce travail a t ralis sur le jeu de donnes mis disposition par les organisateurs du 3rd International Workshop on the Detection and Classification o f Marine Mammals using Passive Acoustics, Boston, Juillet 2007.Ce dernier se compose de donnes d 'entrainement sur trois espces : Msoplodon de Blainville (Mesoplodon densirostris), dauphins de Risso (Grampus griseus) et globicphales (Globicephala macrorhynchus) et de fichiers test.
Copper-Mediated <i>N</i>-Heteroarylation of Primary Sulfonamides: Synthesis of Mono-<i>N</i>-heteroaryl Sulfonamides (2010)

We describe the coupling of primary sulfonamides and various halogenated heterocyclic cores, with an emphasis on 2-heteroaryl halides, via copper catalysis. These studies enabled the synthesis of many new mono-N-heteroaryl sulfonamides. The electronic factors that influence the course of the reaction have also been investigated.
Process discovery using in-database minimum self distance abstractions (2020)

Process executions generate event data that are typically stored in legacy information systems, such as databases. However, process discovery, which requires such event data, is performed in main memory. To bridge this gap, existing techniques must transform and extract event data, which can be expensive steps. This issue has been addressed by processing the event data directly in their origin. However, existing methods rely only on the simplest event data abstraction: the Directly Follows (DF) abstraction. This paper improves upon these existing works by considering another abstraction, the Minimum Self Distance (MSD) abstraction, which enables discovery of a larger class of models than the DF alone. That is, we propose IMw, a process discovery technique without logs and uses both the MSD and DF abstractions. Furthermore, this work proposes an approach to compute the MSD abstraction in-database, thus avoiding the need for transforming and moving event data. We evaluate IMw with real-life logs, and the experimental results show that IMw with in-database abstraction is faster than the traditional approach, aware of dynamic updates on event data, and able to discover models with pareto-optimal results, compared to existing techniques.
Golgi GRASPs: moonlighting membrane tethers (2012)

Abstract: The identification of mammalian Golgi reassembly stacking proteins (GRASPs) 15 years ago was followed by experiments implicating them in diverse functions, including two differing structural roles in Golgi biogenesis and at least two distinct roles in the secretion of proteins. GRASP55 and GRASP65 are localized to cis and medial/trans Golgi cisternae, respectively. They are both required for stacking of Golgi membranes in a Golgi reassembly assay. Depletion of either GRASP from cultured cells prevents the linking of Golgi membranes into their normal ribbon-like network. While GRASPs are not required for transport of secretory cargo per se, they are required for ER-to-Golgi transport of certain specific cargo, such as those containing a C-terminal valine motif. Surprisingly, GRASPs also promote secretion of cargo by the so-called unconventional secretory pathway, which bypasses the Golgi apparatus where the GRASPs reside. Furthermore, regulation of GRASP activity is now recognized for its connections to cell cycle control, development, and disease. Underlying these diverse activities is the structurally conserved N-terminal GRASP domain whose crystal structure was recently determined. It consists of a tandem array of atypical PSD95–DlgA–Zo–1 (PDZ) domains, which are well-known protein–protein interaction motifs. The GRASP PDZ domains are used to localize the proteins to the Golgi as well as GRASP-mediated membrane tethering and cargo interactions. These activities are regulated, in part, by phosphorylation of the large unstructured C-terminal domain. Keywords: GRASP, review, membrane, tether, PDZ domain, secretory chaperone, unconventional secretion
Design of a high speed 12-bit subranging A/D converter (2002)

A high-speed 12-bit subranging analog-to-digital converter (ADC) is presented in the paper. Adapted in the circuit is a 3-stage subranging architecture of "3-bit+3-bit+8-bit", in which the 8-bit ADC is a folding and interpolating ADC, and the error correction is accomplished by analog correction and digital encoding. For fabrication techniques, the 2 /spl mu/m design rule, polysilicon-gate BiCMOS process, laser trimmed SiCr thin film resistor network and double metal routing are employed. SPICE simulation shows a 3 MHz sampling rate has been achieved at /spl plusmn/5 V power supply.
Force Sensing Resistors: A Review Of The Technology (1991)

A demand for an inexpensive, rugged force sensor of qualitative accuracy led to the development of the Force Sensing Resistor (FSR). This device, based on polymer thick film technology, externally resembles a membrane switch, but has a resistance that varies continuously with applied force. It is thin (0.010",typ.), dynamic, insensitive to vibration or normal environmental stresses, and holds up under long-term usage. FSR technology is quickly being integrated into many applications, notably machine control, computer input devices, and composite manufacture.
Reinforcement of Natural Rubber with Silanized Precipitated Silica Nanofiller (2005)

Abstract The effect of a large amount of precipitated amorphous white silica nanofiller, pre-treated with bis[3-triethoxysilylpropyl-)tetrasulfide (TESPT), on the mechanical properties of a sulfur-cured natural rubber (NR) was studied. TESPT chemically adheres silica to rubber and also prevents silica from interfering with the reaction mechanism of sulfur-cure. The silica particles were fully dispersed in the rubber, which was cured primarily by using sulfur in TESPT, or, by adding a small amount of elemental sulfur to the cure system. The cure was also optimized by incorporating sulphenamide accelerator and zinc oxide into the rubber. The hardness, tear strength, tensile strength, and stored energy density at break of the vulcanizate were substantially improved when the filler was added. Interestingly, these properties were also enhanced when the rubber was cured primarily by using sulfur in TESPT.

Plasma synthesis of carbon magnetic nanoparticles and immobilization of doxorubicin for targeted drug delivery (2004)

Using dense medium plasma technology, carbon magnetic nanoparticles (CMNP) were synthesized at room temperature and atmospheric pressure. Based on results from X-ray photoelectron spectroscopy, Fourier transform infrared spectroscopy and scanning electron microscopy, we conclude that these nanoparticles are composed of spherical particles, 40-50 nm in diameter, with iron/iron oxide particles dispersed in a carbon-based host-structure. Thermal gravimetry/differential thermal gravimetry analysis shows these nanoparticles are stable to temperatures as high as 600 degrees C. The synthesized CMNP were treated by argon-plasma, aminated with ethylene diamine and subsequently activated by generating aldehyde groups on them. Free doxorubicin (DOX) molecules were then immobilized onto the surfaces of activated CMNP particles to form CMNP-DOX conjugates. The corresponding loading efficiency was determined. The in vitro antiproliferative activity of immobilized doxorubicin in the conjugates was demonstrated in tumor cell cytotoxicity assays. It is suggested that this CMNP-DOX system can be used for targeted drug-delivery systems.
Effect of chemical composition on work hardening of Fe—Mn—C TWIP steels (2011)

The work hardening behaviour of Fe-Mn-C twinning induced plasticity (TWIP) steels with a wide compositional range has been investigated. Based on the consideration that twinning provides a dynamic composite effect resulting in high work hardening rate in TWIP steels, the present work proposes a model to describe such behaviour as a function of chemical composition. The model predictions are in good agreement with experimental observations.
Intraoperative detection of unsuspected distal coronary obstruction by thermal coronary angiography (1995)

Intraoperative assessment of graft patency and completeness of revascularization can increase the success of coronary artery bypass grafting. A 56-year-old man underwent a quadruple bypass operation. Flow in the graft to the anterior descending artery was verified after completion of the distal anastomosis using a Doppler flow detector. Visualization of the native artery by thermal coronary angiography demonstrated that the flow passed into the second diagonal branch and not into the distal anterior descending artery, which had an unsuspected obstruction just distal to the anastomosis. The obstruction was dilated. Patency was verified with cold solution, and flow of warm blood to the entire artery was accomplished. This case demonstrates how the early (intraoperative) recognition of an unsuspected coronary obstruction using an infrared imaging system can improve the results of myocardial revascularization and avoid potential postoperative complications.
Synthesis of Simplified Hybrid Inhibitors of Type 1 17β-Hydroxysteroid Dehydrogenase via Cross-Metathesis and Sonogashira Coupling Reactions (2004)

[structure: see text] The inhibitor of type 1 17beta-hydroxysteroid dehydrogenase EM-1745 (1) exhibits affinity for both the substrate (estrone or estradiol) and the cofactor (NAD(P)H) binding domains. However, to increase its bioavailability, this compound needs to be simplified. The efficient and convergent synthesis of simplified substrate/cofactor hybrid inhibitors (compounds 2) involving a cross-metathesis and a Sonogashira coupling reaction as key steps is described. Compounds 2a-c were also tested as enzyme inhibitors and compared to EM-1745.
INFLUENCE OF FINING AGENTS ON GLASS MELTING: A REVIEW, PART 1 (2017)

Glass melting is significantly influenced by two processes: the dissolution of particles and the fining of glass. Because these processes are time-and energy-consuming in industry, fining agents are used. Although much literature has been reported about the use of fining agents, no extensive overview of such literature has yet been published. In this paper, we provide such a review, targeting articles that describe the influence of fining agents on (i) the dissolution of particles, (ii) the bubble nucleation and removal, (iii) colour of glass at reduced melting conditions, and (iv) the foaming of glass. We cover the history of fining agent usage from the earliest research in the field to the most recent cutting-edge discoveries. The advantages and disadvantages of all the traditional fining agents are described, with attention paid to the most widely used agent, sodium sulphate. In addition, sodium sulphate is considered as a surface-active compound and colouring substance. Furthermore, we include the influence of redox conditions on the process of fining. We believe that our review provides an ideal introduction to the use of fining agents, both for researchers and industry professionals.

The laser-enhanced chemical etching of Si and Ta with SF 6 , Si, SiO 2 , Ta, and Te films with XeF 2 excited by a pulsed CO 2 laser arid SiO 2 with Cl 2 by a cw Ar + laser has been studied, and the etch rates as a function of the laser wavelength, laser intensity, and gas pressure have been determined.
Circulating tumor cell technologies (2016)

Circulating tumor cells, a component of the "liquid biopsy", hold great potential to transform the current landscape of cancer therapy. A key challenge to unlocking the clinical utility of CTCs lies in the ability to detect and isolate these rare cells using methods amenable to downstream characterization and other applications. In this review, we will provide an overview of current technologies used to detect and capture CTCs with brief insights into the workings of individual technologies. We focus on the strategies employed by different platforms and discuss the advantages of each. As our understanding of CTC biology matures, CTC technologies will need to evolve, and we discuss some of the present challenges facing the field in light of recent data encompassing epithelial-to-mesenchymal transition, tumor-initiating cells, and CTC clusters.
Thermal Stability and Spectroscopic Properties of New Er <sup>3+</sup> /Yb <sup>3+</sup> -Codoped Tellurite Glasses (2004)

A series of new Er3+/Yb3+-codoped 70 TeO2–5 Li2O–(25-x)B2O3–xGeO2 (TLBG, x = 0, 5, 10, 15, 20 mol%) glasses are prepared. The thermal stability and spectroscopic properties of TLBG glasses are studied. It is found that these glasses have the better thermal stability ((Tx−Tg)>150 degrees C) compared with 75 TeO2–20 ZnO–5Na2O (TZN) glass. The fluorescence full width at half maximum (FWHM) is about 77 nm, while the emission intensity and the quantum efficiency of the 4I13/2 level of Er3+ increase with the increasing GeO2 content. The maximum quantum efficiency and stimulated emission cross-section of Er3+ calculated from the McCumber theory are 93.82% and 9.0×10−21 cm2, respectively. The products of FWHM and σepeak of Er3+ in TLBG glasses are larger than those in other reported glasses. The obtained data indicate that this kind of TLBG glasses is a promising candidate host material for Er3+-doped broadband amplifiers.
Volume Visualization of Payoff Regions for Derivatives Risk Management (2001)

Volume visualization of derivatives helps us discover risks, which hitherto have been elusive with traditional surface plots. In this paper, we would like to address the volatility visualization issue, which is one of the critical components in Option pricing, by incorporating volume visualization for better risk management. By enabling the visualization of volatility changes in risk profiling, combining with another two Options value determinants (i.e. the underlying asset spot price and days to maturity), a much better understanding about the risk involved in a portfolio can be achieved, particularly when the fluctuation of the asset is highly uncertain.
Personalized content based image retrieval (2008)

The significant increase in memory technology which provided a substantial boost to the capacity made available to the users as well as the emergence of digital and media technology created important challenges to information processing community as the search for efficient and effective digital image within the range of databases becomes a difficult task. This paper investigates the issue of image retrieval system in the light of LIRE open source system and put forward new formalism for combining text and image attributes. Typically, the image attributes consist of MPEG-7 visual descriptors scalar color, color layour, edge histogram and correlogram while the text attribute conveys the various annotations made by the user to describe the content of the image. Lucene text retrieval was used as a basis to integrate the text component. A similarity measure which reinforces the overlapping outcome among various attributes is put forward. Feasibility and evaluation of the proposal are investigated.
Neighborhood Mixture Model for Knowledge Base Completion (2016)

Knowledge bases are useful resources for many natural language processing tasks, however, they are far from complete. In this paper, we define a novel entity representation as a mixture of its neighborhood in the knowledge base and apply this technique on TransE-a well-known embedding model for knowledge base completion. Experimental results show that the neighborhood information significantly helps to improve the results of the TransE, leading to better performance than obtained by other state-of-the-art embedding models on three benchmark datasets for triple classification, entity prediction and relation prediction tasks.
Probability Distribution Based Resource Management for Transient Resource (2019)

Co-locating latency-critical jobs and batch jobs is an effective way to increase utilization and reduce costs in modern datacenters. The idle resources of latency-critical jobs can be used to run batch jobs, but these transient resources must be revoked whenever latency-critical jobs require them again for guaranteeing their strict quality of service (QoS). The main challenge of this approach is interference between colocated jobs on transient resources. We propose a transient resource management scheme based on probability distribution. Our resource management scheme consist of two components: Tail Latency Aware Allocation (TLAA) and Cost-Effective Resource Revocation (CERR). We character the resource consumption and the completion time of the task of batch jobs and get the probability distribution function of them. Based on the probability distribution of the task resource consumption, we design TLAA to use transient resources efficiently while ensuring tail delay requirements. Based on the probability distribution of the task completion time, we design CERR to revoke transient resources with minimal eviction costs, thereby reducing the impact of resource revocation on batch tasks. Experimental results demonstrate the efficiency of our resource management. TLAA can improve the utilization of transient resources and reduce the completion time of batch jobs to varying degrees under different tail delay requirements. CERR can reduce the impact of resource revocation on batch jobs, and perform better than existing resource revocation strategies.
Recent Progress on Critical Cleaning of Sapphire Single-Crystal Substrates: A Mini-Review (2014)

Sapphire single-crystals are one of the industrial favorite substrates for GaN film deposition and LED application as well as a model system for oxides’ aqueous interfacial chemistry studies. Contamination control of sapphire substrates is critical to the device fabrication and experimental studies of interfacial properties. Here we reviewed various methods reported in the literature including conventional and new wet-chemical methods, and UV/plasma methods. Special attentions were paid to their cleaning performance in terms of reliably removing organic/particulate/heavy metallic contaminants. Keywords: Contamination control, Sapphire, Surface chemistry, Surface structure, UV/plasma cleaning methods, Wetchemical cleaning methods.
