Quasi-Static Analysis of the Multicomponent Mooring Line for Deeply Embedded Anchors (2015)

Multicomponent taut mooring lines are widely used to secure floating facilities to anchors embedded in the seabed to restrict motions. Optimal design of the mooring line system requires a realistic model of the combined performance of all segments of the mooring line, including the separate segments contained within both the water column and the soil column. This paper presents a two-dimensional quasi-static model, which can analyze mooring lines comprising multiple types of mooring lines or chains, taking into account the effects of ocean currents, soil resistance, and elastic elongation of mooring line. An example analysis is carried out to predict the responses of multicomponent mooring line during pretension and under service conditions. The example analysis puts special focus on conditions where the floating facility undergoes a series of motion away from its original position to assess the effect of the vertical offset is studied in detail. Finally, based on the presented model, the performances of different components of the mooring system are thoroughly investigated and some useful conclusions are drawn.
BIST for D/A and A/D converters (1996)

The expense of specialized equipment can be a problem in testing high resolution D/A converters. A BIST alternative that tests offset voltage, integral nonlinearity, differential nonlinearity, and gain error without such equipment or the use of a digital signal processor or microcontroller shows promise. We also extend the same technique to test a wide range of A/D converters.
Microphone array for 2D sound localization and capture (2004)

This work describes two circular microphone arrays and a square microphone array which can be used for sound localization and sound capture. Sound capture by microphone array is achieved by sum and delay beam former (SDBF). A dedicated PCI 128-channel simultaneous input analog-to-digital (AD) board is developed for a 128 ch microphone array with a maximum sampling rate of 22. 7 /spl mu/s/sample. Simulation of sound pressure distribution of 24 and 128 ch circular microphone array and 128 ch square microphone array are shown. Then a 24 ch circular microphone array and a 128 ch square microphone array have been developed. The 24 ch circular microphone array can capture sound from an arbitrary direction. The 128 ch square microphone array can capture sound from a specific point. Both systems are evaluated by using frequency components of the sound. The circular type system can be used on a mobile robot including humanoid robot and square type can be extended towards room coverage type application.
Detection of objects with non-reciprocal properties by polarization radar (2004)

Experimental data from polarimetric radars show, that in some cases the backscattering matrix (BSM) of natural objects does not obey the reciprocity theorem and is not symmetrical. Media, for which the effective backscattering volume is described by an asymmetrical operator, are called non-reciprocal. Achievements in modern radar allow the quasi-simultaneous estimation of all BSM elements in mono-static radar, within a time frame of one radiated waveform only. At the same time, it gives the opportunity to avoid erroneous estimation of BSM asymmetry, which can appear in sequential BSM estimation of non-stable or moving targets. Some theoretical and experimental results of electromagnetic wave hackscattering as well as the proof of possible detection principle of non-reciprocal targets are also presented in the paper.
A cryptic t(5;11)(q35;p15.5) in 2 children with acute myeloid leukemia with apparently normal karyotypes, identified by a multiplex fluorescence in situ hybridization telomere assay (2002)

The identification of specific chromosome abnormalities in acute myeloid leukemia (AML) is important for the stratification of patients into the appropriate treatment protocols. However, a significant proportion of diagnostic bone marrow karyotypes in AML is reported as normal by conventional cytogenetic analysis and it is suspected that these karyotypes may conceal the presence of diagnostically significant chromosome rearrangements. To address this question, we have developed a novel 12-color fluorescence in situ hybridization (FISH) assay for telomeric rearrangements (termed M-TEL), which uses an optimized set of chromosome-specific subtelomeric probes. We report here the application of the M-TEL assay to 69 AML cases with apparently normal karyotypes or an isolated trisomy. Of the 69 cases examined, 3 abnormalities were identified, all in the normal karyotype group. The first was a t(11;19)(q23;p13), identified in an infant with AML-M4. In 2 other young patients with AML (< 19 years), an apparently identical t(5;11)(q35;p15.5) was identified. Breakpoint mapping by FISH and reverse transcriptase polymerase chain reaction (RT-PCR) analysis confirmed that this was the same t(5;11) as previously identified in 3 children with AML, associated with del(5q) and resulting in the NUP98-NSD1 gene fusion. The t(5;11) was not detected by 24-color karyotyping using multiplex FISH (M-FISH), emphasizing the value of screening with subtelomeric probes for subtle translocations. This is the first report of the t(5;11)(q35;p15.5) in association with an apparently normal karyotype, and highlights this as a new, potentially clinically significant chromosome rearrangement in childhood AML.

Micro-RNA in Patients with Carotid Atherosclerosis (2020)

Atherosclerosis is a multifactorial disease and one of the leading causes of ischaemic stroke. In recent years, microRNA has become an important factor to consider in the pathogenesis of atherosclerosis. MicroRNAs are non-coding RNA sequences that are divided into proatherogenic and atheroprotective. This study evaluated the leukocyte expression of certain microRNAs (miR-126-(5p/3p), miR-29a-(5p/3p), miR-33a-5p and miR-21-(5p/3p)) in patients with carotid atherosclerosis. Statistically significant differences were found between patient groups in regard to the molecular levels, as well as correlations between several microRNAs. This indicates the potential use of microRNA in diagnosis and treatment, and confirms the role of microRNAs as important regulators of carotid atherosclerosis.

An integrated optic adiabatic TE/TM mode splitter on silicon (1993)

A compact integrated optic fundamental TE/TM mode splitter, based on the mode-sorting characteristics of an asymmetrical adiabatic Y junction of optical waveguides exhibiting shape birefringence, operating at 1550 nm, is designed, using the discrete sine method (DSM) and the beam propagation method (BPM). The structures are fabricated in a system of SiO/sub 2/, SiO/sub x/N/sub y/, and Si/sub 3/N/sub 4/ layers, using a low-temperature plasma-enhanced chemical-vapor deposition (PECVD) process, compatible with standard silicon IC processing.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Effects of Polychlorinated Biphenyls on Lignin Biosynthesis in Arabidopsis thaliana (2021)

Growing bioenergy feedstock plants on contaminated land for the combined benefits of bioenergy production and land remediation is an attractive strategy to increase the cost-efficiency of plant-based biofuel. However, prior research has suggested that toxic stress increases the lignin content in exposed plants, which may affect the biomass digestibility and its conversion into bioethanol. In this study, we have conducted a transcriptomic analysis to determine the effect of a polychlorinated biphenyl (PCB), 2,5-dichlorobiphenyl (2,5-DCB), and its hydroxylated derivative, 4′-hydroxy-2,5-dichlorobiphenyl (4′-OH-2,5-DCB), on lignin biosynthesis in the model plant, Arabidopsis thaliana. Both 2,5-DCB and 4′-OH-2,5-DCB induced many genes involved in lignin biosynthesis. A 5.1- and 4.9-fold enrichment of genes involved in the phenylpropanoid pathway were observed in plants exposed to 2,5-DCB and 4′-OH-2,5-DCB, respectively. The upregulated expression of peroxidase, glutathione S-transferase, and glycosyltransferase genes also suggested an activation of the metabolism of xenobiotics in the plant tissues. The lignin content in exposed plants was analyzed using Fourier-transformed infrared spectroscopy (FTIR), confirming that exposure to the two compounds significantly increased the lignin content. Our results suggest for the first time that the exposure of plants to persistent organic pollutants (POPs) may cause an increase of lignin biosynthesis.
Performance of Axial-Flow Supersonic Compressor of XJ55-FF-1 Turbojet Engine. III; Over-All Performance of Compressor (1949)

An investigation was conducted to determine the performance characteristics of the rotor and inlet guide vanes used in the axial-flow supersonic compressor of the XJ55-FF-1 turbojet engine. Outlet stators used in the engine were omitted to facilitate study of the supersonic rotor. The extent of the deviation from design performance indicates that the design-shock configuration was not obtained. A maximum pressure ratio of 2.26 was obtained at an equivalent tip speed of 1614 feet per second and an adiabatic efficiency of 0.61. The maximum efficiency obtained was 0.79 at an equivalent tip speed of 801 feet per second and a pressure ratio of 1.29. The performance obtained was considerably below design performance. The effective aerodynamic forces encountered appeared to be large enough to cause considerable damage to the thin aluminum leading edges of the rotor blades.
Endoscopic management of duodeno-ileal fistula secondary to diffuse B-cell lymphoma (2017)

Lymphoma arising in the gastrointestinal tract is relatively common and can affect multiple sites. The development of a gastrointestinal fistula secondary to lymphoma is very rare and has not previously been reported between the duodenum and ileum. This is the first reported care where a fistula secondary to lymphoma has been treated by an endoscopic covered duodenal stent occluding the defect rather than surgical intervention. This strategy permitted early commencement of curative intent chemotherapy which led to tumour shrinkage and fistula closure.
Piezoelectric cellular micro-structured PDMS material for micro-sensors and energy harvesting (2015)

This paper reports a novel low-cost fabrication process of a charged cellular microstructured polydimethylsiloxane (PDMS) material referred as piezo-electret or ferro-electret for micro-sensors applications. The dielectric spectra reached on these structures exhibit a high piezoelectric longitudinal coefficient d33 of 350pC/N. A mechanical characterization method proves the reliability of this material for low-frequencies applications around 100Hz.
Development of a scintillating G-GEM detector for a 6-MeV X-band Linac for medical applications (2013)

The temporal signals from a large gas detector may show dynamical scaling due to many correlated space points created by the charged particles while passing through the tracking medium. This has been demonstrated through simulation using realistic parameters of a Time Projection Chamber (TPC) being fabricated to be used in ALICE collider experiment at CERN. An interesting aspect of this dynamical behavior is the existence of an universal scaling which does not depend on the multiplicity of the collision. This aspect can be utilised further to study physics at the device level and also for the online monitoring of certain physical observables including electronics noise which are a few crucial parameters for the optimal TPC performance.
Mass Range (2016)

This document contains recommendations for terminology in mass spectrometry. Development of standard terms dates back to 1974 when the IUPAC Commission on Analytical Nomenclature issued recommendations on mass spectrometry terms and definitions. In 1978, the IUPAC Commission on Molecular Structure and Spectroscopy updated and extended the recommendations and made further recommendations regarding symbols, acronyms, and abbreviations. The IUPAC Physical Chemistry Division Commission on Molecular Structure and Spectroscopy’s Subcommittee on Mass Spectroscopy revised the recommended terms in 1991 and appended terms relating to vacuum technology. Some additional terms related to tandem mass spectrometry were added in 1993 and accelerator mass spectrometry in 1994. Owing to the rapid expansion of the field in the intervening years, particularly in mass spectrometry of biomolecules, a further revision of the recommendations has become necessary. This document contains a comprehensive revision of mass spectrometry terminology that represents the current consensus of the mass spectrometry community.
Réactualisation en Temps Réel de Profils de Densité électronique Ionosphérique (1992)

Le milieu ionospherique, caracterise par son profil de densite electronique en fonction de l'altitude, presente une grande variabilite spatiale et temporelle. L'obtention de ce profil se fait actuellement, soit a partir d'une modelisation s'appuyant sur les nombreuses donnees acquises anterieurement, soit a partir de mesures de temps de propagation obtenues par des sondeurs verticaux ou obliques travaillant entre 2 et 25 MHz. L'operation qui consiste a passer des mesures de temps de propagation au profil de densite est appelee inversion. La variabilite temporaire de l'ionosphere necessite, pour la plupart des applications, l'obtention du profil de densite aux moins toutes les 15 min. Le passage d'un profil a un autre correspond a ce que nous denommons reactualisation

Cache-in-the-Middle (CITM) Attacks: Manipulating Sensitive Data in Isolated Execution Environments (2020)

The traditional usage of ARM TrustZone has difficulty on solving the conflicts between the manufacturers that want to minimize the trusted computing base by constraining the installation of third-party applications in the secure world and the third-party application developers who prefer to have the freedom of installing their applications into the secure world. To address this issue, researchers propose to create Isolated Execution Environments (called IEEs) in the normal world to protect the security-sensitive applications. In this paper, we perform a systematic study on the IEE data protection models and the ARM cache attributes, and discover three cache-based attacks called CITM that can be leveraged to manipulate the sensitive data protected in IEEs. Specifically, due to the inefficient and incoherent security measures on the cache that maps to the IEE memory (i.e., memory designated for IEEs), attackers in the normal world may compromise the security of IEE data by manipulating the IEE memory during concurrent execution, bypassing the security measures enforced when a security-sensitive application is suspended or finished, or misusing the incomplete security measures during IEE's context switching processes. We conduct case studies of CITM attacks on three well-known IEE systems including SANCTUARY, Ginseng, and TrustICE to illustrate the feasibility to exploit them on real hardware testbeds. Finally, we analyze the root causes of the CITM attacks and propose a countermeasure to defeat them. The experimental results show that our defense scheme has a small overhead.

Characterization of the Hox cluster from the mosquito Anopheles gambiae (Diptera: culicidae) (2000)

The Hox genes have been found to encode transcription factors, which specify the morphological identity of structures along the anteroposterior axis of animals ranging from worms to mice. The canonical set of nine genes is organized in a cluster in the genome of several protostomes and deuterostomes. However, within insects, whereas the Hox genes are organized in a single cluster in the beetle Tribolium castaneum, they are split into two separate groups in the flies Drosophila melanogaster and Drosophila virilis. The significance of a split Hox cluster is unknown and has been observed in only one organism outside the Drosophila lineage: the nematode Caenorhabditis elegans. We have cloned a majority of the Hox genes from the mosquito Anopheles gambiae (Diptera: Culicidae) and compared their genomic organization with that of Tribolium and Drosophila to determine if a split Hox cluster is found in dipterans aside from the Drosophilidae. We find that the Hox genes in Anopheles, as in Tribolium, are organized in a single cluster that spans a genomic region of at least 700 kb. This finding suggests that, within the insect genome, the partition of the Hox cluster may have evolved exclusively within the Drosophila lineage. The genomic structures of the resident genes, however, appear to be largely conserved between A. gambiae and D. melanogaster.
Hybrid assembly technology for flip-chip-on-chip (FCOC) using PBGA laminate assembly (2002)

Component integration is becoming more and more popular to achieve reduction of space with increasing performance of electronic packages. Dual-Chip-Stack (DCS) is the direct, face to face joining of two (or more) semiconductor devices. It improves significantly component integration by leveraging flip-chip technology processing, standard wirebond packaging and plastic ball grid array (PBGA) processes. High bandwidth interconnections between devices of various process technologies allow the construction of unique, high margin component assemblies. In this paper, the authors describe the assembly development work of a DCS package using a logic device attached to a DRAM device over a PBGA chip-up type carrier. Proposed packaging flow is discussed with process modifications to obtain a robust product. The processes discussed are: flip-chip dicing, device to device joining, wirebond to laminate carrier, and encapsulation (Underfill and Globtop). Some reliability results will also be shown and discussed.
α‐Oligofurans: A Computational Study (2013)

Recently, α-oligofurans have emerged as interesting and promising organic electronic materials that have certain advantages over α-oligothiophenes. In this work, α-oligofurans were studied computationally, and their properties were compared systematically with those of the corresponding oligothiophenes. Although the two materials share similar electronic structures, overall, this study revealed important differences between α-oligofurans and α-oligothiophenes. Twisting studies on oligofurans revealed them to be significantly more rigid than oligothiophenes in the ground state and first excited state. Neutral α-oligofurans have more quinoid character, higher frontier orbital energies, and higher HOMO-LUMO gaps than their α-oligothiophene counterparts. The theoretical results suggest that oligofurans (and subsequently polyfuran) have lower ionization potentials than the corresponding oligothiophenes (and polythiophene), which in turn predicts that oligofurans can be lightly doped more easily than oligothiophenes. Oligofuran dications (8 F(2+)-14 F(2+)) of medium-sized and longer chain lengths show a polaron-pair character, and the polycations of α-oligofurans cannot accommodate high positive charges as easily as their thiophene analogues.
Model-based segmentation of the left main coronary bifurcation from 2D angiograms (2012)

This paper deals with the identification of the left main coronary bifurcation (LMB) in 2D angiograms. We resort to a generic 3D model of the LMB that is projected in the proper angulation to retrieve the expected 2D skeleton of the LMB in the considered image. We derive from it an efficient discriminating filter that allows detecting the LMB, while being robust to anatomical variations. We demonstrate the potential of the method over a large database of 120 angiographic sequences from 15 patients. We also propose a method extension that exploits not only the present angiography, but also the previous ones, as acquired in the course of the exam.
