Locking frequency band detection method for grid-tied PV inverter islanding protection (2015)

Islanding is an undesired event in which a portion of utility system containing both load and distributed resources remains energized while it is isolated from the remainder of the utility system. In case of islanding, successful detection is required to protect the equipment, and provide safety of the maintenance service workers. This paper shows an implementation of a novel algorithm named Locking Frequency Band Detection (LFBD) method on a distributed PV inverter architecture. Fast detection, easy implementation, no impact on the power quality and zero Non Detection Zone (NDZ) are among many benefits of the proposed algorithm.

How network asymmetry affects TCP (2001)

Several emerging wireline and wireless access network technologies exhibit asymmetry in their network characteristics. For instance, cable modem networks exhibit significant bandwidth asymmetry, while packet radio networks exhibit media access asymmetry. A high degree of asymmetry can have an adverse effect on the performance of feedback-based transport protocols. We study the effects of bandwidth and media access asymmetry on the performance of the TCP protocol. We identify the fundamental reasons for the mismatch between TCP and asymmetric networks, and then present several techniques to address this problem.
Inhibition of sperm-zona binding by suramin, a potential ‘lead’ compound for design of new anti-fertility agents (1996)

Progress in developing new contraceptive agents, particularly for the male, is extremely slow. Here, we report on a novel property of the anti-trypanosomal drug suramin: the ability to act at the sperm-egg interface and prevent fertilization. Suramin is a polysulphonated compound that inhibits binding of capacitated mouse spermatozoa to the zona pellucida in vitro with an IC50 of 12.4 microM. The drug is only effective at the time of fertilization and is not inhibitory if gametes are pre-treated separately. Autoradiographic localization of suramin binding sites on mouse, boar and human spermatozoa shows that they are intracellular, principally in the head region. The sperm protein recognized by suramin has been identified as proacrosin which is known to interact with sulphate groups on zona glycoproteins. Zona pellucida glycoproteins do not bind suramin, suggesting that the drug blocks the ability of proacrosin/acrosin, exposed during the acrosome reaction, to mediate the secondary binding phase of spermatozoa to the zona during fertilization. Structure-based design studies have the potential to generate safe suramin mimetics that would form the basis for a new generation of non-steroidal contraceptive agents.
Towards a UML Profile for Model-Based Risk Assessment (2002)

The EU-funded CORAS project (IST-2000-25031) is developing a framework for model-based risk assessment of security-critical systems. This framework is characterised by: (1) A careful integration of aspects from partly complementary risk assessment methods. (2) Guidelines and methodology for the use of UML to support and direct the risk assessment methodology. (3) A risk management process based on AS/NZS 4360 and ISO/IEC 17799. (4) A risk documentation framework based on RM-ODP. (5) An integrated risk management and system development process based on UP. (6) A platform for toolinclusion based on XML. This paper focuses on one specific aspect of the CORAS framework, namely the CORAS UML profile for risk assessment. In particular, it explains its role in the CORAS risk management process and demonstrates its use in the risk assessment of an e-Commerce system.
[Treatment of anemia in chronic renal failure by a long-activing activator of erythropoiesis]. (2002)

This novel long acting activator of the erythropoiesis is efficient and safe for the treatment of anemia of IRC patients. Its prolonged half-life, the delay between injections, and the decrease in the frequency of dose changes might result in an advantage for the patients and the medical staff.
A planar dielectrophoresis-based chip for high-throughput cell pairing (2017)

A planar dielectrophoresis-based chip for high-throughput single cell–cell pairing (with a pairing efficiency up to 74.2%) was developed.
Chromosomal analysis of human prostatic adenocarcinoma cell lines. (1980)

Although detailed cytogenetic analysis has been carried out in many types of cancer, there is little information on the chromosomal makeup of prostatic cancer cells. Karyological analyses of cell lines derived from both metastatic and primary prostatic carcinoma have been carried out by Q-, C-, and sequential banding techniques. The metastatic line, PC-3, isolated from a bone marrow specimen, is an established epithelial line which is tumorigenic in nude, athymic mice and forms colonies in semisolid agar suspension. A subline, PC-3/M, was isolated from a PC-3-induced mouse tumor. Karyotypic analysis of PC-3 by Q- and C-banding showed the cells to be aneuploid at all culture passage levels. The modal chromosome number shifted from 62 to 55 between the 5th and 50th passages. PC-3 has a unique karyotype. Chromosomes 2, 3, 5, 15, and Y were always absent. At least 11 different marker chromosomes were observed. The subline, PC-3/M, had a similar karyotype and retained the parental PC-3 markers. PC-3/M had a more restricted chromosomal frequency distribution range. Nearly 73% of the PC-3/M cells examined had 60 or 61 chromosomes in contrast to the wide distribution seen in PC-3. Silver staining for nucleolus organizer regions indicated that the number of functional nucleolus organizer regions in PC-3 was proportional to the number of acrocentric chromosomes. Banding analysis of PC-5-PI isolated from primary prostatic adenocarcinoma indicated that this line also had a characteristic karyotype with 28% pseudodiploid and 72% pseudotetraploid components. All metaphases examined were partially trisomic in chromosome 9 and lacked a demonstrable Y chromosome.
High-power-coupled CO2 waveguide laser array (1986)

Progress in phase-locked diode arrays has resulted in higher coherent output power than is obtainable with single-diode lasers. Recently, this general concept was applied to CO2 waveguide lasers in which a two-element array was phase-locked at the 1-W output power level by optically coupling the two-laser element through a transparent partition.1 Here we report phase-locked operation of two- and three-element CO2 waveguide laser arrays at the 50-W output power level using a ridge waveguide optical coupling technique to achieve phase locking. Our results to date indicate that scaling the output power of sealed-off C02 waveguide laser arrays to the 100-W to 1-kW power level should be possible in the near future. This level is over an order of magnitude higher than typical output power levels generated by single-channel CO2 waveguide lasers.
cw optically pumped 12-μm NH3 laser (1982)

A 30-W cw CO2 laser operating on the R(30) 9-μm transition is used to pump a ring laser cavity containing NH3. Emission at 12.08 μm is observed with cw output power of 180 mW. A Raman process is shown to be responsible for the gain at 12.08 μm.
Synthesis and characterization of nanozeolites (2006)

Dans cette thèse, deux nouvelles méthodes ont été étudiées en vue de synthétiser des nanozéolithes à savoir la synthèse en mono-phase et la synthèse en deux-phases. La méthode en deux-phases consiste à introduire un solvant organique contenant l'organosilane à la solution aqueuse de synthèse de zéolithe donnant lieu à un mélange de deux-phases. Après agitation et traitement hydrothermique de ce mélange, des nanozéolithes organosilane-fonctionnalisées ont été obtenues en phase organique, tandis que de gros cristaux de zéolithe ont été trouvés dans la phase aqueuse. Dans la méthode mono-phasée, une quantité appropriée de gel de zéolithes en solution a été ajoutée à une solution du toluène/n-butanol contenant des organosilanes. Après 12 heures d'agitation à 60°C, on obtient un mélange en une seule phase. Ce mélange a subit ensuite une cristallisation hydrothermique pour donner naissance à des nanozéolithes fonctionnalisées. En principe, les deux méthodes utilisent l'organosilane pour empêcher la croissance de zéolithe. Le solvant organique agit en tant que milieu favorable à la dispersion des nanozéolithes fonctionnalisées par l'organosilane provenant de la phase aqueuse, ce qui mène à un arrêt complet du processus de croissance. On démontre que ces deux méthodes sont applicables à la synthèse des nanozéolithes de silicalite-1 et FAU et peuvent s'appliquer à la synthèse d'autres types de zéolithes. Des techniques de caractérisation comprenant DRX, IR ont été employées pour déterminer la structure zéolithique des échantillons. La taille de cristal a été vérifiée par analyses de MEB et de MET. Adsorption/désorption de l'azote a été effectuée pour évaluer la surface spécifique des échantillons. La fonctionnalisation des nanozéolithes a été étudie par29SiRMN. L'activité catalytique des nanozéolithes synthétisées a été évaluée par la réaction du craquage de TIPB. Les résultats préliminaires ont montré que les nanozéolithes de FAU peuvent être un excellent catalyseur pour la réaction du craquage.
Redox outside the Box: Linking Extracellular Redox Remodeling with Intracellular Redox Metabolism (2011)

Aerobic organisms generate reactive oxygen species as metabolic side products and must achieve a delicate balance between using them for signaling cellular functions and protecting against collateral damage. Small molecule (e.g. glutathione and cysteine)- and protein (e.g. thioredoxin)-based buffers regulate the ambient redox potentials in the various intracellular compartments, influence the status of redox-sensitive macromolecules, and protect against oxidative stress. Less well appreciated is the fact that the redox potential of the extracellular compartment is also carefully regulated and is dynamic. Changes in intracellular metabolism alter the redox poise in the extracellular compartment, and these are correlated with cellular processes such as proliferation, differentiation, and death. In this minireview, the mechanism of extracellular redox remodeling due to intracellular sulfur metabolism is discussed in the context of various cell-cell communication paradigms.
NAD <sup>+</sup> repletion improves muscle function in muscular dystrophy and counters global PARylation (2016)

Neuromuscular diseases are often caused by inherited mutations that lead to progressive skeletal muscle weakness and degeneration. In diverse populations of normal healthy mice, we observed correlations between the abundance of mRNA transcripts related to mitochondrial biogenesis, the dystrophin-sarcoglycan complex, and nicotinamide adenine dinucleotide (NAD<sup>+</sup>) synthesis, consistent with a potential role for the essential cofactor NAD<sup>+</sup> in protecting muscle from metabolic and structural degeneration. Furthermore, the skeletal muscle transcriptomes of patients with Duchene's muscular dystrophy (DMD) and other muscle diseases were enriched for various poly[adenosine 5'-diphosphate (ADP)-ribose] polymerases (PARPs) and for nicotinamide N-methyltransferase (NNMT), enzymes that are major consumers of NAD<sup>+</sup> and are involved in pleiotropic events, including inflammation. In the mdx mouse model of DMD, we observed significant reductions in muscle NAD<sup>+</sup> levels, concurrent increases in PARP activity, and reduced expression of nicotinamide phosphoribosyltransferase (NAMPT), the rate-limiting enzyme for NAD<sup>+</sup> biosynthesis. Replenishing NAD<sup>+</sup> stores with dietary nicotinamide riboside supplementation improved muscle function and heart pathology in mdx and mdx/Utr<sup>-/-</sup> mice and reversed pathology in Caenorhabditis elegans models of DMD. The effects of NAD<sup>+</sup> repletion in mdx mice relied on the improvement in mitochondrial function and structural protein expression (α-dystrobrevin and δ-sarcoglycan) and on the reductions in general poly(ADP)-ribosylation, inflammation, and fibrosis. In combination, these studies suggest that the replenishment of NAD<sup>+</sup> may benefit patients with muscular dystrophies or other neuromuscular degenerative conditions characterized by the PARP/NNMT gene expression signatures.
Biosynthesis of Proteoglycans by Rat Granulosa Cells Cultured in Vitro: Modulation by Gonadotropins, Steroid Hormones, Prostaglandins, and a Cyclic Nucleotide (1981)

Rat ovarian granulosa cells were isolated from immature female rats 48 h after stimulation with 5 IU PMS gonadotropin and then maintained in culture. The effects of ovine (o)FSH, oLH, hCG, testosterone, 17 beta-estradiol, progesterone, prostaglandins E1, E2, F1 alpha, F2 alpha, N,O'-dibutyryl cAMP, and theophylline on proteoglycan synthesis by the granulosa cells in vitro were examined using [35S]sulfate as a precursor. oFSH, oLH, hCG, prostaglandins E1 and E2, N,O'-dibutyryl cAMP, theophylline and testosterone stimulated the production of 35S-labeled proteoglycans compared to control cultured. 17 beta-Estradiol, progesterone, and the prostaglandins F1 alpha, and F2 alpha, showed no stimulation. Two major species of proteoglycan are synthesized and secreted into the medium: 1) a population with large hydrodynamic size (Kav = 0.30 on Sepharose CL-2B); and 2) a population with relatively small size (Kav = 0.60 on Sepharose CL-2B). The stimulatory effect of the hormones was accounted for entirely by a net increase in synthesis of the smaller proteoglycan population. The hormones exert their stimulatory effects on proteoglycan synthesis at concentrations similar to those required for other in vitro biological responses of granulosa cells.
BIOLOGICAL ACTIVITIES OF ALLIUM SATIVUM (1969)

Allium sativum (Garlic) is a cultivated vegetable. Al-Rawi and Chakravarty (1) indicated the therapeutic use of the bulb and juice of this plant. Actually the bulb is used in various forms of ulcers and regulation of the menstrual cycle. The juice is also used as a rubefacient in skin diseases and external ottitis and as a lotion for washing the wounds and ulcers. In addition to the wind-breaking and helminthic effect, the juice showed an improvement of the urinary secretion and sweating and an antipyretic effect in the patient with an intermittent fever. Thus, the main therapeutic indications of the juice as a syrup are diaphoretic, diuretic and expectorant effects. Inspite of the wide therapeutic availability, the biological activity of this plant is little known. Therefore, in the present experiments the effects of water and alcohol extracts of Allium sativum on the various organ functions were observed.
DVB-H - the emerging standard for mobile data communication (2005)

The digitization of traditional broadcast systems has made significant progress in recent years. This development could be observed recently with respect to the standard for digital terrestrial television, DVB-T (Digital Video Broadcasting – Terrestrial), which is already in operation in many countries throughout the world. Currently, the system is being rolled out in Germany and the UK (the Freeview DTT platform). DVB-T has also started in the Netherlands and Italy and was announced to start in France in early 2005; further countries have plans to start services in the near future. In many countries, the decision to select DVB-T as the terrestrial television system was based on the exceptional features of the DVB-T standard, among them the possibility to receive broadcast services also with portable devices and even in cars.

Fully automated fluorescence assay for determining total homocysteine in plasma. (1989)

Homocysteine exists in human plasma as various (mixed) disulfides. Most plasma homocysteine (about 70%) is protein bound, probably via a disulfide bond to albumin, whereas homocysteine-cysteine mixed disulfide is the predominating form in the free fraction. We here present a method for the determination of total homocysteine, which includes both fractions. Plasma was initially treated with sodium borohydride to reduce the disulfide bonds, and the liberated thiols were derivatized with monobromobimane. The derivatized sample, still containing the plasma proteins, was injected onto a strong cation-exchange column, from which the homocysteine derivative was directed by column switching into a cyclohexyl silica (CH) column. The homocysteine derivative was top-concentrated on the CH column, then rapidly eluted with a steep gradient of methanol. Both the derivatization procedure and chromatography were performed with a combined sample processor and sample injector from Gilson (Model 232-401). Within-run and between-run precision (CV) was less than 4%, and the detection limit of 0.2 pmol was sufficiently low for monitoring homocysteine in plasma. We verified the assay against two established manual methods for the determination of total homocysteine in plasma. This, the first fully automated assay for total plasma homocysteine, allows the unattended analysis of 70 samples per 24 h.
Design and Characterization of Current-Assisted Photonic Demodulators in 0.18- $\mu\hbox{m}$ CMOS Technology (2011)

We report on the design of a current-assisted photonic demodulator (CAPD) using standard 0.18-μm complementary metal-oxide-semiconductor technology and its electrooptical characterization. The device can perform both light detection and demodulation in the charge domain, owing to a drift field generated in the silicon substrate by a majority carrier flow. Minimum-sized 10 × 10 μm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> CAPDs exhibit a direct-current charge-transfer efficiency larger than 80% (corresponding to demodulation contrast larger than 40% under sine-wave modulation) at the modest power consumption of 10 μW and a 3-dB bandwidth of >; 45 MHz. An excellent linearity value with an error lower than 0.11% is obtained in phase measurements. CAPDs with optimized modulation electrode geometries are finally designed, aiming at an improved contrast-versus-power tradeoff.
Tyramide Signal Amplification (TSA)-FISH Applied to Mapping PCR-Labeled Probes Less than 1 kb in Size (1999)

Tyramide signal amplification (TSA)-FISH was used to map one mouse and two human DNA probes of less than 1 kb in size. The two human probes were 319 and 608 bp, and the mouse probe was 855 bp. Probes, made from PCR products, were labeled by incorporating biotin-11-dUTP (human) and biotin-16-dUTP (mouse) during PCR amplification. Signals were readily observed in both interphase and metaphase cells following TSA-FISH for all three genes, whereas conventional FISH experiments produced no signals. The two human ATP-binding cassette (ABC) genes, EST883227 (GenBank Accession No. AA243820) and EST990006 (GenBank Accession No. AA348546), mapped to human chromosomes 7p21 and 17q25. The mouse gene, cmyc (exon 2) mapped to band D2 of mouse chromosome 15. These findings demonstrate the ability of this technique to map small probes (PCR products and expressed sequence tags) of less than 1 kb through highly increased signal amplification.
Slower rise of exhaled breath temperature in chronic obstructive pulmonary disease (2003)

In chronic obstructive pulmonary disease (COPD) there is decreased vascularity of the bronchi and inflammation of the airways that may have opposite effects on the regulation of heat loss. Exhaled air temperature increase (delta(e) T) was measured in 23 patients with moderate COPD (18 male, mean age +/- SEM 70 +/- 1 yrs; forced expiratory volume in one second (FEV1) 45 +/- 3%, FEV1/forced vital capacity 54 +/- 4%) and 16 normal volunteers (64 +/- 4 yr) and compared to exhaled nitric oxide (eNO) and inflammatory cells in induced sputum as a marker of airway inflammation. Delta(e) T was measured during a flow- and pressure-controlled single exhalation with a fast-response thermometer. delta(e) T was reduced in patients with COPD (1.86 +/- 0.15 delta C x s(-1)) compared to normal subjects (4.00 +/- 0.26 delta C x s(-1)). There was no difference in delta(e) T between patients treated with inhaled steroids and those who were steroid naïve. Delta(e) T was correlated with eNO (r=0.60) but not with sputum neutrophilia. In COPD patients, delta(e) T was increased (2.26 +/- 0.16 delta C x s(-1)) after the inhalation of 200 microg of albuterol, which is a known vasodilator, indicating that delta(e) T and bronchial blood flow may be correlated. Exhaled temperature increase is reduced in chronic obstructive pulmonary disease patients and is increased by the inhalation of vasodilators and therefore may be related to changes of bronchial blood flow and tissue remodelling.
Clustering in canine malignant lymphoma (1994)

A clustering of generalized malignant lymphoma is reported in a single household of Rottweiler dogs (both parents and three of the four sibling in one litter) and in a breeding pair of unrelated Scottish terriers. In addition, malignant lymphoma of the myocardium was found in three directly related otterhounds (the sire and two sibling offspring). Possible genetic and viral factors in the aetiology of canine malignant lymphoma are discussed.
Evolution of Next Generation Networks towards an Integrated Platform for IMS-Based IPTV Services (2007)

Next generation networks offer dedicated subsystems for each task to be fulfilled within the overall architecture defined in TISPAN NGN Release 1. There exist different subsystems for PSTN/ISDN emulation, streaming services and the 3GPP driven IP multimedia subsystem (IMS) which has been adapted to the NGN architecture. In NGN Release 2.0 IPTV shall be integrated into that architecture to support extended streaming services for next generation television. Current developments within ETSI TISPAN show two different approaches when speaking of the integration of IPTV services into the NGN: one IMS-based solution that relies on IMS/SIP signaling for new services and a non-IMS black box approach as an independent NGN subsystem. Our research activities are focused on the IMS-based activities and aim on the development of a reference architecture and on the service definition towards the now starting ETSI TISPAN standardization activities. This work shall introduce our architecture approach and evaluation based on precedent scenario and requirement analysis
The Synthesis of Magnetic Core‐Shell Nanoparticles by Surface‐Initiated Ring‐Opening Polymerization of <i>ε</i>‐Caprolactone (2005)

Abstract Summary: The synthesis of core‐shell particles with a poly( ε ‐caprolactone) (PCL) shell and magnetite (Fe 3 O 4 ) contents of between 10 wt.‐% and 41 wt.‐% proceeds by surface‐initiated ring‐opening polymerization of ε ‐caprolactone to give surface‐immobilized oligomers with $\overline M _{\rm n}$ between 1 400 g · mol −1 and 11 500 g · mol −1 . The particles are dispersable in good solvents for the PCL shell. Magnetization experiments on the resulting superparamagnetic ferrofluids give a core‐size distribution with an average diameter, d v , of about 9.7 nm.
