Long-span repeaterless transmission systems with optical amplifiers using pulse width management (1998)

This paper proposes pulse width management in order to extend the repeater spacings of repeaterless transmission systems with optical amplifiers. First, the dependency of receiver sensitivity on duty ratio, receiver response, and fiber dispersion is clarified by numerical analysis. Next, the calculation results of sensitivity as a function of signal format and receiver basedband response are verified experimentally. Moreover, we show that pulse width management which uses return-to-zero (RZ) format with large duty ratio (/spl sim/0.7) at the transmitter and pulse compression at the receiver increases the repeater gain by /spl sim/4.5 dB compared to conventional systems employing nonreturn-to-zero (NRZ) format. Record repeater spacing of 300 km is realized at 10 Gb/s by utilizing pulse width management.
Use of RAPD PCR to Distinguish the B Biotype from Other Biotypes of <i>Bemisia tabaci</i> (Gennadius) (Hemiptera: Aleyrodidae) (1997)

The use of RAPD PCR to identify the B biotype of the whitefly Bemisia tabaci and distinguish it from other biotypes and species of whitefly is described. the technique enables the use of alcohol preserved material instead of live or frozen material as required by allozyme electrophoresis and demonstrates that eggs, juvenile stages and males or females can all be used.
Integrated Autonomous System for Exploration and Navigation in Underground Mines (2006)

This paper describes an autonomous platform for exploration and navigation within networks of tunnels, as those typically found in underground mines and caves. In this context, we propose a system allowing two modes of operation: exploration/surveying mode and autonomous navigation mode. In the exploration mode, a remotely located supervisor instructs the platform to move through successive sections of the network, gathering range data that is then concatenated into 2D/3D survey maps of the environment. In the navigation mode, the supervisor specifies high-level missions on the previously acquired survey maps. A motion planner then translates each mission into a set of consecutive navigation actions, separated by natural landmarks. Mission execution consists of autonomously detecting landmarks, self-localizing and performing the planned navigation actions. Advanced and innovative features, mostly related to exploration capabilities, navigation mode switcher, and the integrated aspect of our system distinguish it from the systems described in the literature
Hydroxy-telechelic copolyesters with well defined sequence structure through ring-opening polymerization (2000)

New well-defined macrodiols were prepared by ring-opening copolymerization of lactones and cyclic diesters with a low molecular weight diol. Suitable monomers are diglycolide, L,L-dilactide, ε-caprolactone, and rac-β-butyrolactone. With exception of rac-β-butyrolactone, the reaction can be performed with or without a catalyst. The use of a catalyst influences the sequence structure of the telechelics. Copolyesterdiols from ε-caprolactone, diglycolide, and ethylene glycol with random, blocky, and intermediate structure were synthesized and characterized. The analogous copolyesterdiols from L,L-dilactide, ε-caprolactone, and ethylene glycol were also prepared. The sequence structure of the random chains with diglycolide corresponds to a random distribution of glycolate units, that of the corresponding chains with L,L-dilactide exhibit a random distribution of L,L-dilactate units.
A Novel Combinatorial Approach to High-Density Peptide Arrays (2009)

Combinatorial synthesis of peptides on solid supports (1), either as spots on cellulose membranes (2) or with split-pool-libraries on polymer beads (3), substantially forwarded research in the field of peptide-protein interactions. Admittedly, these concepts have specific limitations, on one hand the number of synthesizable peptide sequences per area, on the other hand elaborate decoding/encoding strategies, false-positive results and sequence limitations. We recently established a method to produce high-density peptide arrays on microelectronic chips (4). Solid amino acid microparticles were charged by friction and transferred to defined pixel electrodes onto the chip's surface, where they couple to a functional polymer coating simply upon melting (Fig. 16.1 A-D,F). By applying standard Fmoc chemistry according to Merrifield, peptide array densities of up to 40,000 spots per square centimetre were achieved (Fig. 16.1G). The term "Merrifield synthesis" describes the consecutive linear coupling and deprotecting of L-amino acids modified with base-labile fluorenylmethoxy (Fmoc) groups at the N-terminus and different acid-sensitive protecting groups at their side chains. Removing side chain protecting groups takes place only once at the very end of each synthesis and generates the natural peptide sequence thereby.

Implementation of Lawful Interception Within IMS (2008)

Lawful interception is a system which monitors a user or a communication in the support of criminal investigation. It is a necessary function of the telecommunication operator. The telecommunication standards bodies such as ETSI, 3GPP are producing technical specifications on lawful interception system, and have developed standards on handover areas and interception areas which can guide the implement. IP Multimedia Subsystem (IMS) is a new core-network architecture introduced after the version of 3GPP Release 5, which is layer-designed, IP-based, and using Session Initiation Protocol (SIP) as application protocol. There are two typical implementations of lawful interception within IMS, distributed type and centralized type.
Psychoactive Substance Use Disorders in Women (1994)

Throughout history, virtually every society that has permitted the personal use of psychoactive substances has had different usage rules for men and women. These differences, dating back at least as far as the Code of Hammurabi, are based on deeply held ideas about the differential effects of alcohol and other drugs on each gender. Although there are many similarities in the way psychoactive substance abuse and dependence affects men and women, there are also profound differences. These differences are shaped in large part by social and environmental factors and are also based on genetic, physiological, and psychological differences. This presentation summarizes special features of alcohol and other drug problems in women along with patterns of dual diagnosis particular to women. It also discusses how these problems relate to women's sexual and reproductive functioning and the victimization of women. The contribution of these problems to the current public policy discussion on best how to meet the needs of pregnant addicts is also examined.

SpamRank - fully automatic link spam detection. Work in progress (2005)

Spammers intend to increase the PageRank of certain spam pages by creating a large number of links pointing to them. We propose a novel method based on the concept of personalized PageRank that detects pages with an undeserved high PageRank value without the need of any kind of white or blacklists or other means of human intervention. We assume that spammed pages have a biased distribution of pages that contribute to the undeserved high PageRank value. We define SpamRank by penalizing pages that originate a suspicious PageRank share and personalizing PageRank on the penalties. Our method is tested on a 31 M page crawl of the .de domain with a manually classified 1000-page stratified random sample with bias towards large PageRank values.
Experimental validation of sound field control with a circular double-layer array of loudspeakers (2013)

This paper is concerned with experimental validation of a recently proposed method of controlling sound fields with a circular double-layer array of loudspeakers [Chang and Jacobsen, J. Acoust. Soc. Am. 131(6), 4518-4525 (2012)]. The double-layer of loudspeakers is realized with 20 pairs of closed-box loudspeakers mounted back-to-back. Source strengths are obtained with several solution methods by modeling loudspeakers as a weighted combination of monopoles and dipoles. Sound pressure levels of the controlled sound fields are measured inside and outside the array in an anechoic room, and performance indices are calculated. The experimental results show that a method of combining pure contrast maximization with a pressure matching technique provides only a small error in the listening zone between the desired and the reproduced fields, and at the same time reduces the sound level in the quiet zone as expected in the simulation studies well above the spatial Nyquist frequency except at a few frequencies. It is also shown that errors in the positions of the loudspeakers can be critical to the results at frequencies where the distance between the inner and the outer array is close to half a wavelength.

Isolation and characterization of two human transcription factor IIH (TFIIH)-related complexes: ERCC2/CAK and TFIIH. (1996)

Transcription factor IIH (TFIIH) is a multisubunit protein complex essential for both the initiation of RNA polymerase class II (pol II)-catalyzed transcription and nucleotide excision repair of DNA. Recent studies have shown that TFIIH copurifies with the cyclin-dependent kinase (cdk)-activating kinase complex (CAK) that includes cdk7, cyclin H, and p36/MAT1. Here we report the isolation of two TFIIH-related complexes: TFIIH* and ERCC2/CAK. TFIIH* consists of a subset of the TFIIH complex proteins including ERCC3 (XPB), p62, p44, p41, and p34 but is devoid of detectable levels of ERCC2 (XPD) and CAK. ERCC2/CAK was isolated as a complex that exhibits CAK activity that cosediments with the three CAK components (cdk7, cyclin H, and p36/MAT1) as well as the ERCC2 (XPD) protein. TFIIH* can support pol II-catalyzed transcription in vitro with lower efficiency compared with TFIIH. This TFIIH*-dependent transcription reaction was stimulated by ERCC2/CAK. The ERCC2/CAK and TFIIH* complexes are each active in DNA repair as shown by their ability to complement extracts prepared from ERCC2 (XPD)- and ERCC3 (XPB)-deficient cells, respectively, in supporting the excision of DNA containing a cholesterol lesion. These data suggest that TFIIH* and ERCC2/CAK interact to form the TFIIH holoenzyme capable of efficiently assembling the pol II transcription initiation complex and directly participating in excision repair reactions.
Cytogenetic studies of a male with sporadic intestinal lymphangiectasia: 45,X/46,XY mosaicism with pseudo‐ and hyperdiploid subpopulations in cultured tissues (1979)

Abstract 45,X/46,XY mosaicism was found in peripheral blood, bone marrow, and tissue cultures of an adult male with intestinal lymphangiectasia (IL). Turner phenotype was not present; his meiotic metaphase analysis was normal, and his dermatoglyphics resembled those of his family. Ten separate tissue culture lines from three biopsies of skin and thyroid gland contained 45,X cells (14.8 to 78.3%). Autosomal aneuploidy, resulting in pseudo‐ or hyperdiploidy, was also present in 4.3 to 41.6% of the cells. A hyperdiploid clone with a 47,X,+10,+18 karyotype was found in 22.6% of cells in one line. A second hyperdiploid clone with a 48,X,+2,+18,+18 karyotype occurred in 7.6% of cells from another line containing a total of 41.6% pseudo‐ and hyperdiploid cells. Such clonal abnormalities were not typical of tissue cultures from other patients done in our laboratory. Growth of our patient's tissue cultures was subnormal, and none proliferated beyond the fourth subculture. The significance of this observation remains to be determined. Our results do not allow us to conclude whether our patient's mosaicism of somatic tissues arose during embryogenesis, or whether it originated post‐natally. The secondary immunodeficiency which occurs in IL may explain persistence of cells with unusual combinations of autosomal aneuploidy in our patient's tissues.
NLNDE: Enhancing Neural Sequence Taggers with Attention and Noisy Channel for Robust Pharmacological Entity Detection (2019)

Named entity recognition has been extensively studied on English news texts. However, the transfer to other domains and languages is still a challenging problem. In this paper, we describe the system with which we participated in the first subtrack of the Phar-maCoNER competition of the BioNLP Open Shared Tasks 2019. Aiming at pharmacological entity detection in Spanish texts, the task provides a non-standard domain and language setting. However, we propose an architecture that requires neither language nor domain expertise. We treat the task as a sequence labeling task and experiment with attentionbased embedding selection and the training on automatically annotated data to further improve our system's performance. Our system achieves promising results, especially by combining the different techniques, and reaches up to 88.6% F1 in the competition.
Behavioural and pharmacological relevance of stroke-prone spontaneously hypertensive rats as an animal model of a developmental disorder (2002)

The present study evaluates juvenile stroke-prone spontaneously hypertensive rats (SHRSP) as an animal model of a developmental disorder, which is diagnosed according to hyperactivity-impulsivity and/or inattention. To characterize behavioural alterations, we studied motor activity, as well as emotional and cognitive behaviours in juvenile SHRSP, with and without methylphenidate, a psychostimulant. Ambulatory and rearing activities in the open-field environment were significantly higher in SHRSP than in Wistar-Kyoto rats (WKY). In the elevated plus maze task, the entries into open arms, as an index of impulsivity, were significantly increased in SHRSP. In the Y-maze task, spontaneous alternation behaviour, as an index of attention, was significantly lowered in the male SHRSP, but not in the female SHRSP, indicating that spontaneous alternation deficit is gender specific. Methylphenidate (0.01-1 mg/kg, i.p.) significantly attenuated locomotor hyperactivity at low doses and dose-dependently improved the spontaneous alternation deficit in SHRSP. Our findings reveal that juvenile SHRSP manifest problematic behaviours resembling a developmental disorder, attention-deficit/hyperactivity disorder (ADHD), namely hyperactivity-impulsivity and/or inattention. Methylphenidate alleviated the behavioural symptoms of hyperactivity and inattention. We propose that juvenile SHRSP are an appropriate animal model of a developmental disorder resembling ADHD, from behavioural and pharmacological perspectives.
Characterisation of 20-kDa lectin-spermagglutinin from<i>Arum maculatum</i>that prevents<i>Chlamydia pneumoniae</i>infection of L-929 fibroblast cells (2002)

A novel lectin from the root of Arum maculatum was isolated by saline extraction and purified by cold ethanol precipitation and subsequent fractionation on Superose 6 column. The lectin named A. maculatum agglutinin is a non-glycosylated protein with 20-kDa molecular mass agglutinating human ejaculated spermatozoa, but not human erythrocytes. The agglutination was blocked in the presence of N-acetylneuraminic acid indicating that the lectin is sialoglycoprotein specific. Chlamydia pneumoniae strain AR-39 showed considerable potential to grow in murine L-929 fibroblast cells. Pretreatment of the cell monolayers with purified lectin reduced the entry and intracellular replication of C. pneumoniae. These results suggest that the isolated lectin prevents attachment by binding to a C. pneumoniae specific sialoglycoprotein receptor expressed on the surface of L-929 fibroblast cells.
Setting temperatures of synthetic casts. (1985)

We used a glass tube containing water at body temperature to simulate a lower limb and applied commonly used synthetic-cast materials to this artificial limb in order to measure the exotherm created by these materials. Tests were limited to six plies and were done with and without a pillow under the cast. If the instructions called for the use of dip water, we used water at 24, 32, and 40 degrees Celsius. Under these conditions, none of the commonly used synthetic materials created temperatures that were high enough to cause burns.
Effect of Hetero-Valent-Ion Doping in the High T<sub>c</sub> Y-Ba-Cu-O Superconductor (1987)

Effect of hetero-valent-ion (Ce and La) doping on the resistive transition of the high T c superconductor Y 0.33 Ba 0.67 CuO n or Y 0.37 Ba 0.63 CuO n has been investigated. The midpoint of the resistive transition is found to decrease and the width to increase, with increase of the doping. Unstable resistive anomaly at a higher temperature is also observed.
Polyphase multivibrators (1967)

A new type of polyphase multivibrator is introduced in which saturable cores are the timing elements and transistors the switching elements. The basic units are like the multivibrators invented by Royer and others, but, in the new polyphase circuit, several single-phase multivibrators with a common dc source are constrained by a loop connection of windings on the cores in such a way that polyphase output voltages are obtained. Detailed analysis of a typical 3-phase circuit leads to conclusions regarding the frequency of oscillation and the output voltage waveforms which conform to experimental observations. Novel arrangements are presented by means of which 2-phase voltages can be obtained from a 3-phase multivibrator.
