Influence of Porous Coating Level on Proximal Femoral Remodeling (2000)

This study used femurs retrieved at autopsy to compare the extent and location of bone remodeling between four patients implanted with proximally porous coated femoral prostheses and a matched group of four patients implanted with extensively porous coated femoral prostheses. The femoral components studied were large, cementless, straight, cobalt chrome stems and were identical except for the amount of porous coating. The contralateral normal femur of each patient also was retrieved, implanted with an identical prosthesis, and used as a control for bone mineral content. Dual energy x-ray absorptiometric analysis showed marked loss of bone mineral content in both groups of patients. The extensively coated group had less bone loss on average (18.4%) than did the proximally coated group (38.6%). There was no relationship between the extent of coating and the location of bone mineral loss; specifically, proximal coating did not protect against loss of bone mineral content proximally or distally in the femur. Videodensitometric analysis of cross sections of periprosthetic bone also showed that the extensively coated group tended to have less decrease in bone density than did the proximally coated group (14.3% versus 28.4%). Although one cannot presume that all proximally fixed stem designs would produce results similar to those presented here, these findings show that decreasing the extent of porous coating alone does not necessarily reduce proximal femoral bone loss.
A generic methodology for partitioning unorganised 3D point clouds for robotic vision (2004)

Range image segmentation has many applications in computer vision areas such as computer graphics and robotic vision. A generic methodology for 3D point set analysis in which planar structures play an important role is defined. It consists mainly of a specific K-means algorithm which is able to process different shapes in cluster. At the same time, within geometric and topologic considerations, a set of application-driven heuristics is designed. This helps to find out the right number of structures in point sets in order to give a good visualization and representation of a large scale environment without a priori models. Our aim is to propose a simple and generic frame for 3D scene understanding. Tests were realised on different types of environment data: natural and man-made. This research project has been realized with EADS (French Air Space Society).
Synthesis of Polypeptides Related to Porcine Proinsulin (1972)

Syntheses are described of eleven protected peptide fragments which cover the entire sequence of porcine proinsulin and of two partially protected polypeptides which correspond to the 17–84 and 15–84 amino acid sequences, respectively, of porcine proinsulin. The amino acid sequences of the two partially protected polypeptides are illustrated in the text. In these peptides, the sulfhydryl group of cysteine is protected with the ethylcarbamyl function, and the s-amino group of lysine is blocked with the formyl function. The partially protected octahexacontapeptide I cross-reacted with anti-synthetic porcine connecting peptide antisera to the same extent as did the porcine proinsulin or the synthetic connecting peptide. Heptacontapeptide II cross-reacted with antisera to porcine proinsulin and slightly with antisera to porcine insulin.
Metodología para el estudio del comportamiento de parafinas en operaciones de producción de hidrocarburos. (2008)

Paraffin precipitation occurs in many oil fields causing problems and increasing the operational costs, which in severe cases and without a proper diagnosis and control in few time can lead to loss of wells. To avoid such problems is necessary to characterize adequately the fluid and its thermodynamic and compositional behavior, to assess the conditions under which possibly happen the phenomenon of deposition. In order to achieve this is necessary, to take a representative sample of the fluid to study experimentally the phenomenon and fit a model that identifies it, for implement prevention and control methods that contribute to the solution. This article presents the methodology followed to study the behavior of wax.In This paper presents the methodology obtained for studying the behavior of wax in mature fields, which was developed, implemented and improved in the research for determining the onset of wax precipitation in crude oil field Colorado.
A mechanical analysis of woodpecker drumming and its application to shock-absorbing systems (2011)

A woodpecker is known to drum the hard woody surface of a tree at a rate of 18 to 22 times per second with a deceleration of 1200 g, yet with no sign of blackout or brain damage. As a model in nature, a woodpecker is studied to find clues to develop a shock-absorbing system for micromachined devices. Its advanced shock-absorbing mechanism, which cannot be explained merely by allometric scaling, is analyzed in terms of endoskeletal structures. In this analysis, the head structures (beak, hyoid, spongy bone, and skull bone with cerebrospinal fluid) of the golden-fronted woodpecker, Melanerpes aurifrons, are explored with x-ray computed tomography images, and their shock-absorbing mechanism is analyzed with a mechanical vibration model and an empirical method. Based on these analyses, a new shock-absorbing system is designed to protect commercial micromachined devices from unwanted high-g and high-frequency mechanical excitations. The new shock-absorbing system consists of close-packed microglasses within two metal enclosures and a viscoelastic layer fastened by steel bolts, which are biologically inspired from a spongy bone contained within a skull bone encompassed with the hyoid of a woodpecker. In the experimental characterizations using a 60 mm smoothbore air-gun, this bio-inspired shock-absorbing system shows a failure rate of 0.7% for the commercial micromachined devices at 60 000 g, whereas a conventional hard-resin method yields a failure rate of 26.4%, thus verifying remarkable improvement in the g-force tolerance of the commercial micromachined devices.
Natural Language Inference over Interaction Space (2017)

Natural Language Inference (NLI) task requires an agent to determine the logical relationship between a natural language premise and a natural language hypothesis. We introduce Interactive Inference Network (IIN), a novel class of neural network architectures that is able to achieve high-level understanding of the sentence pair by hierarchically extracting semantic features from interaction space. We show that an interaction tensor (attention weight) contains semantic information to solve natural language inference, and a denser interaction tensor contains richer semantic information. One instance of such architecture, Densely Interactive Inference Network (DIIN), demonstrates the state-of-the-art performance on large scale NLI copora and large-scale NLI alike corpus. It's noteworthy that DIIN achieve a greater than 20% error reduction on the challenging Multi-Genre NLI (MultiNLI) dataset with respect to the strongest published system.
Crosstalk and its power penalty in multichannel transmission due to gain saturation in a semiconductor laser amplifier (1989)

A theoretical study of channel crosstalk due to gain saturation in a laser amplifier in multichannel transmission is discussed. When the amplifier is gain-saturated, the gain of any channel is influenced by the light intensity of the other channels, which causes channel crosstalk in intensity-modulated multiplexing transmission. On-off-keying modulation systems with more than two channels are discussed. Considering the probability distribution, the power penalty due to crosstalk is presented for practical system design. Calculated examples reveal that the power penalty is dependent on both the level of gain saturation and the number of multiplexed channels.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Novel Metal‐Polyurethane Complexes with Enhanced Antimicrobial Activity (2006)

Abstract Summary: The silver coating of polymers has been intensively investigated in the last few decades as an effective non‐resistance‐inducing strategy to prevent medical device‐related infections. We have developed a completely new approach to incorporate silver ions in polymers by the synthesis of a carboxylated polyurethane able to coordinate Ag + . The obtained polymers possess mechanical properties suitable for the development of medical devices, without any risk of loss of activity. To minimize the risk of increasing antibiotic resistance, the metal ion‐containing polymers are loaded with ciprofloxacin, which possesses a different mechanism of antimicrobial action, thus a system able to inhibit Staphylococcus epidermidis and Pseudomonas aeruginosa growth for at least one month is developed. SEM images showing a mature S. epidermidis biofilm on the surface of the carboxylated polyurethane (left) and the surface of the silver ion‐containing polyurethane free from bacterial colonization (right) after 48 h of incubation. magnified image SEM images showing a mature S. epidermidis biofilm on the surface of the carboxylated polyurethane (left) and the surface of the silver ion‐containing polyurethane free from bacterial colonization (right) after 48 h of incubation.

Borazine Based Molecular Single Source Precursors for Si/B/N/C Ceramics  (2010)

Abstract The family of borazines [(SiCl 3 )NB(Cl n (CH 3 ) 1– n ] 3 was synthesized and characterized by NMR and IR spectroscopy, as wellas by single crystal structure analysis. After cross‐linking with methylamine, a soluble polymer was obtained that was transformed to anall‐inorganic random network of nominal composition Si 1.0 B 1.0 N 3.0 C 0.9 O 0.1 (idealized SiBN 3 C) at 1400 °C. With an on‐set of weight loss at 1840 °C and a resistance against rapid oxidation in pure oxygen of up to 1300 °C, the new Si/B/N/C ceramic shows a high temperature performance similar to those of previously reported Si/B/N/C materials.
Effect of rotor dimensions and cross magnetisation on L <sub>d</sub> and L <sub>q</sub> inductances of reluctance synchronous machine with cageless flux barrier rotor (1994)

The performance of a reluctance synchronous machine in terms of torque and power factor depends on the two-axis inductances Ld and Lq of the machine. A finite element analysis method is used to determine these inductances for a reluctance machine with a normal cross-laminated rotor with two flux barriers per pole. By varying the rotor dimensions, the change in the difference and ratio of the inductances is examined. The effect of cross magnetisation on the two axis inductances is investigated by means of finite element analysis and measurements on an actual reluctance synchronous machine with a two flux barrier per pole rotor. The measured torque of the current-controlled reluctance machine drive is also given and compared with calculated results showing the effect of cross magnetisation. Hence, important conclusions are arrived at regarding the rotor design and cross magnetisation effect.
Image quality assessment of color LCD monitors by polychromatic modulation transfer function (2005)

컬러 LCD(liquid crystal display) 모니터의 광학적 상에 대한 성능을 평가하기 위하여 LCD 모니터를 포함한 모든 광학계의 파장별 공간주파수 반응에 가중치를 부여한 진폭전달함수(modulation transfer function ; MTF)를 이용한 다색광전달함수(polychromatic modulation transfer function ; PMTF)를 제안한다. 서로 다른 진폭들을 갖는 적색(R), 녹색(G), 청색(B)의 3개의 막대형 LCD 단위물체를 이용한 컬러 LCD의 PMTF의 시뮬레이션 결과와 실험적 결과가 잘 일치하며, 이 결과 컬러 LCD의 결상성능은 단색으로 측정하는 MTF 및 가시광의 전파장대를 사용하는 백색광 MTF와는 다른 R, G, B의 3색에 대한 PMTF로 측정하늘 것이 보다 적절하다. We propose a method for evaluating the image quality of color liquid crystal display(LCD) monitors by using the polychromatic modulation transfer function(PMTF), which is calculated from the modulation transfer function(MTF) weighted by the overall color response of the system including the test LCD monitor. We confirm that experimental results using the PMTF agree well with simulated results of the PMTF of a color LCD monitor by using three bar targets with different amplitudes and three elementary colors such as red(R), green(G), and blue(B). As a results, we should choose the PMTF instead of the white color MTF or monochromatic MTF in order to evaluate correctly the image quality of color LCD monitors.
Convergence Towards Next Generation Wireless Networks (2013)

The communications sector is undergoing significant changes, with the emergence of a number of platforms available to provide a different range of services. Some of these platforms are complementary, others are competitive, or can provide a valid substitute for some of the services provided. Till now, the most important communications platform in most of the countries is the public switched telecommunication network (PSTN), which provides access to all households and buildings across most countries. This paper focuses on the area where the most significant changes are taking place in the communications sector. This paper gives a description of the wire line and wireless (NGN) networks, its basics, its transformation to wireless technology, need for convergence towards next generation networks and the future of NGN networks. The focus is on the next generation access and core networks, it is because they are changing the public switched telecommunication networks, the changes taking place in the PSTN are considerable. For over 100 years copper has been used as the transmission technology in the local loop to connect each home and building to the telecommunication network. Copper is increasingly being replaced by fibre in the local loop while packet-based technology using the Internet Protocol is replacing existing circuit-based switching technologies. This paper describes the need of wireless technology, why and how it becomes essential in terms of technological, social and economic need of the society. It tells us about how the circuit switched technology has been switched to IP technology and how the PSTN networks, which are circuit switched will be converted to packet-based networks These changes affect existing regulations and policy frameworks, convergence, investment and choice in the market place. Finally it concludes with the latest developments, which are going on in Wireless systems.
Discovery of activity patterns using topic models (2008)

In this work we propose a novel method to recognize daily routines as a probabilistic combination of activity patterns. The use of topic models enables the automatic discovery of such patterns in a user's daily routine. We report experimental results that show the ability of the approach to model and recognize daily routines without user annotation.
Automatic generation of explanations for spreadsheet applications (2002)

Applications developed by end-users using spreadsheets cannot be effectively distributed to other users because of the need for adequate information on the functioning of the applications themselves. In fact, building an explanation facility to support an application is a time-consuming task. This paper illustrates the realization of a tool for the automatic generation of explanations in conventional spreadsheet applications. The system works in two stages: the first one corresponds to the construction of a knowledge base containing the information on the mathematical relations coded into a programmed spreadsheet; the second one consists of the generation of explanations (concerning the quantities used in the spreadsheet and their relationships) from the representation previously built.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Effect of very early intervention with metoprolol on myocardial infarct size. (1983)

All patients with a presumptive diagnosis of myocardial infarction, who were seen within six hours of the onset of symptoms and had no reason for exclusion, were considered for entry into a trial to compare the effects of metoprolol and placebo on creatine kinase MB isoenzyme release. The trial was randomised and double blind. The median time from onset of symptoms to receiving trial drug was just under two hours. Two hundred and four patients (of whom 120 had myocardial infarction) received metoprolol and 187 (of whom 105 had myocardial infarction) received placebo. Infarct size was estimated semiquantitatively using cumulative release of the cardiospecific isoenzyme, creatine kinase MB. Mean creatine kinase MB isoenzyme was less in patients who received metoprolol, but the reduction did not achieve statistical significance. Clinical problems related to early intravenous metoprolol were uncommon.
Transforming growth factor‐β<sub>3</sub> affects plasminogen activator inhibitor‐1 expression in fetal mice and modulates fibroblast‐mediated collagen gel contraction (2006)

For over two decades, the precise role of transforming growth factor-beta (TGF-beta) isoforms in scarless healing of mammalian fetal skin wounds has generated much interest. Although their exact role remains to be established, it has been suggested that high TGF-beta3 activity may correlate with a scarless phenotype. Previously, we showed that plasminogen activator inhibitor-1 (PAI-1), a known TGF-beta downstream molecule and marker of fibrosis, is also developmentally regulated during fetal skin development. In this study, the relationship between TGF-beta3 and PAI-1 was investigated using embryonic day 14.5 TGF-beta3 knockout (ko) mice. The results showed increased PAI-1 expression in the epidermis and dermis of ko mice, using an ex vivo limb-wounding study. Furthermore, increased PAI-1 expression and activity was seen in embryo extracts and conditioned media of ko dermal fibroblasts. When TGF-beta3 knockout fibroblasts were placed into three-dimensional collagen matrices, they were found to have decreased collagen gel contraction, suggesting altered cell-matrix interaction. These findings provide a further avenue for the interactive role of TGF-beta3 and PAI-1 during fetal scarless repair.
Adaptive Path Isolation for Elephant and Mice Flows by Exploiting Path Diversity in Datacenters (2016)

Resource competition and conflicts in datacenter networks (DCNs) are frequent and intense. They become inevitable when mixing elephant and mice flows on shared transmission paths, resulting in arbitration between throughput and latency and performance degradation. We propose a novel flow scheduling scheme, Freeway, that leverages on path diversity in the DCN topology to guarantee, simultaneously, mice flow completion within deadline and high network utilization. Freeway adaptively partitions the available paths into low latency and high throughput paths and provides different transmission services for each category. A M/G/1-based model is developed to theoretically obtain the highest value of average delay over the path that will guarantee for 99% of mice flows their completion time before the deadline. Based on this bound, Freeway proposes a dynamic path partitioning algorithm to adjust dynamically with varying traffic load the number of low latency and high throughput paths. While mice flows are transmitted over low latency paths using a simple equal cost multiple path (ECMP) scheduling, Freeway load balances elephant flows on different high-throughput paths. We evaluate Freeway in a series of simulation on a large scale topology and use real traces. Our evaluation results show that Freeway significantly reduces the mice flows completion time within deadlines, while achieving remarkable throughput compared with current schemes. It is remarkable that Freeway does not need any change of DCN switch fabrics or scheduling algorithms and can be deployed easily on any generic datacenter network with switches implementing VLANs and trunking.
Event-Related Potentials in Human Immunodeficiency Virus Infection (1992)

P3 event-related evoked potentials (ERP) were recorded from 47 human immunodeficiency virus (HIV)-positive subjects examined twice and 29 HIV-positive subjects examined three times at 6-month intervals. The P3 latency significantly increased over time for asymptomatic subjects and subjects with acquired immunodeficiency syndrome (AIDS) and AIDS-related complex. N2 latency was prolonged relative to control values in both HIV-positive groups but did not increase with time. The P3 latency correlated with neuropsychologic measures of motor control and speed of mental processing. Confounding factors (active or previous substance abuse, developmental disabilities, and history of closed head injury or epilepsy) did not significantly affect ERP latencies. Endogenous ERP components are frequently abnormal in HIV-positive subjects and the P3 latency progressively increases over time. Continued follow-up is required to determine the clinical utility of ERP studies in the HIV-positive population.
