Use of cell and protoplast cultures for banana improvement biotechnologies (1993)

L'extension de certaines maladies des bananiers a induit la création de cv. résistants. Les outils de la biotechnologie sont envisagés pour compléter les méthodes classiques d'amélioration des bananiers. 1 système fiable de régénération à partir de cultures de protoplastes de bananiers a été développé avec succès à l'Université Paris Sud, en utilisant des suspensions de cellules embryogènes compétentes comme source de protoplastes. Mis en co-culture, à haute densité sur un milieu adéquat, avec des suspensions cellulaires soit de Lolium soit de bananier, les protoplastes de bananiers sont capables de reformer la paroi cellulaire en moins de 24 h, et d'assumer des divisions après 3 à 5 j. Les protoplastes isolés à partir de cellules triploïdes embryogènes jeunes et actives ont donné des embryons globuleux qui se développeront ultérieurement en plantules. Des résultats prometteurs peuvent être obtenus par hybridation somatique.
Secure data transfer in MANET using symmetric and asymmetric cryptography (2015)

MANET is ad-hoc network in which mobile nodes co-operatively route the traffic to the nodes which are beyond their direct range. The mobile nodes are free to join or leave the network at will. The open architecture and dynamic topology coupled with lack of infrastructure make MANET vulnerable to variety of attacks at all layers. The secure transmission of data over MANET is a critical requirement. In this paper we have proposed a technique which provides secure transmission of data. The technique involves encryption of data using symmetric cryptographic technique, and also generating the digital signature of the data using the asymmetric cryptographic technique from the Hash of the data. The encrypted data is transmitted through the network to the destination where the received data and digital signature of the data are validated using symmetric and asymmetric cryptography. The data on validation is accepted thus ensuring secure data transmission. The proposed technique provides confidentiality, integrity, authenticity and non-repudiation to the data. It protects the data transmitted over the network from snooping, modification, replay and fabrication attack at the application layer.
Effect of the Addition of Water-Soluble Polymeric Species on the Encapsulation of Pigments by Soap-Free Emulsion Polymerization (1995)

二種類の水溶性高分子物質の添加がソープフリー重合による顔料のカプセル化にどのような影響を及ぼすかについて検討された。ここで検討された顔料は, 不溶性ジスアゾ (Index No.PY17), フタロシアニン (Index No.PB15 : 3) およびカーボンブラック (#15) である。これらの顔料は重合に先立ち水溶性高分子水溶液中に分散された。添加された水溶性高分子はヒドロキシプロピルメチルセルロース (HPMC) とポリビニルアルコール (PVA) である。カプセル化に用いたモノマーはメタクリル酸メチル (MMA) である。実験では, カプセル化の状態が, 重合度の異なるHPMCを添加して主に検討された。HPMCやPVAを個々に添加するより, これらの混合系を添加することによりカプセル化が良好であることが分かった。
Self-organized form birefringence in glass irradiated by intense ultrashort light pulses (2003)

Correlation between anisotropic reflection and birefringence in glass irradiated with femtosecond pulses is observed. Direct evidence of self-induced nanogratings and form birefringence is obtained.
Understanding and Addressing CLSI Breakpoint Revisions: a Primer for Clinical Laboratories (2019)

The Clinical and Laboratory Standards Institute (CLSI) has revised several breakpoints since 2010 for bacteria that grow aerobically. In 2019, these revisions include changes to the ciprofloxacin and levofloxacin breakpoints for the <i>Enterobacteriaceae</i> and <i>Pseudomonas aeruginosa</i>, daptomycin breakpoints for <i>Enterococcus</i> spp., and ceftaroline breakpoints for <i>Staphylococcus aureus</i> Implementation of the revisions is a challenge for all laboratories, as not all systems have FDA clearance for the revised (current) breakpoints, compounded by the need for laboratories to perform validation studies and to make updates to laboratory information system/electronic medical record builds in the setting of limited information technology infrastructure. This minireview describes the breakpoint revisions in the M100 supplement since 2010 and strategies for the laboratory on how to best adopt these in clinical testing.
PVD-PECVD Hybrid Processes: Synthesis of Composite Thin Films and Process Understanding (2008)

After reviewing most of the recent developments performed on hybrid processes, basic physical phenomena of PVD-PECVD processes are detailed with the help of a model showing the different influences of main process parameters. Ti-Si-O and Zn-Si-O thin films are synthesized as possible examples of composite thin films. Limitations of the model developed are also discussed with respect to the composition and structure of deposited thin films.
Early primary graft failure after a pediatric heart transplant and successful rescue with plasmapheresis, immunoglobulins, and alemtuzumab (2016)

Early primary graft failure after pediatric orthotopic heart transplantation (OHT) has a high mortality rate and can occur due to several causes including but not limited to prolonged graft ischemia time, suboptimal preimplant myocardial preservation, hyperacute rejection, and maladaptation of the graft to the host's hemodynamic status. Mechanical circulatory support with either extracorporeal membrane oxygenation (ECMO) or ventricular assist device has been used for the rescue of primary graft failure in pediatric patients after heart transplant. Cardiac arrest before ECMO initiation in these patients is associated with adverse neurologic outcome although those surviving to hospital discharge generally have excellent long-term outcome. We report a case of early primary graft failure after OHT who required ECMO support and successful rescue with plasmapheresis, immunoglobulins, and alemtuzumab.
Squeezing of pulses in a nonlinear interferometer (1990)

A symmetric nonlinear Mach–Zehnder interferometer containing a Kerr medium performs the operation of squeezing. The operation is performed by the interference of cotraveling waves, and the pump wave is removed. This mechanism is broadband. We analyze the operation of the interferometer and determine the degree of shot-noise reduction achieved in a balanced detector. A modification of the interferometer into a fiber ring reflector is described that accomplishes the squeezing and the pump separation.
Study on photovoltaic grid-connected inverter control system (2009)

The grid-connected photovoltaic generation system is the most important one in the field of photovoltaic application. In this paper, a model of photovoltaic has been constructed based on the main circuit of single phase grid-connected generation system using MATLAB/simulink to program it. The double closed loop control structure is adopted and forward-feed compensation method is employed to the system. It made the grid-connected current track the presetting sinusoidal reference signal in real time. The analytical and simulated results show that the grid-connected current waveform of the system is improved effectively and a faster dynamic response is obtained and forward-feed compensation control depress the grid disturbance.
Directed Metalation Cascade To Access Highly Functionalized Thieno[2,3-<i>f</i>]benzofuran and Exploration as Building Blocks for Organic Electronics (2013)

A tandem directed metalation has been successfully applied to the preparation of thieno[2,3-f]benzofuran-4,8-dione, providing an efficient and facile approach to symmetrically and unsymmetrically functionalize the thieno[2,3-f]benzofuran core at the 2,6 positions as well as to introduce the electron-withdrawing or -donating groups (EWG or EDG) at its 4,8 positions. The presence of various functional groups makes late-stage derivatization attainable.
Nuclear Weapons and NATO: is it safer to deter or to disarm? (2016)

Debates about whether to retain or abolish nuclear weapons have intensified. The North Atlantic Treaty Organization (NATO) maintains its nuclear weapons are essential to the alliance’s security. NATO’s 2010 Strategic Concept reasserted in 2014 that, “As long as nuclear weapons exist, NATO will remain a nuclear alliance.” Conversely, many observers of the negotiations regarding the United Nations (UN) Non-Proliferation of Nuclear Weapons Treaty (NPT) argue the Nuclear Weapon States (NWS) in the 28-member NATO alliance are obliged to move NATO’s posture toward nuclear disarmament rather than deterrence. The resarch project analyses the arguments in favour of the alliance’s continued reliance upon nuclear weapons and the arguments against its current security policy. The research project investigates the systemic-, state- and individual-level factors that interact to produce longstanding policies as well as divisive debates about NATO’s nuclear weapons. A core objective is to explain debates concerning NATO’s nuclear weapons in the context of global negotiations at UN headquarters between 1995 and 2020 about nuclear proliferation and disarmament. Two research questions are investigated: What are the distinguishing features of the NATO security policy, specifically what are its objectives, goals, and instruments? What multilateral initiatives at the UN by coalitions of Non-Nuclear Weapon States (NNWS), non-governmental organizations (NGOs) and individuals have attempted to change longstanding nuclear policies? The research project explains the struggles over nuclear weapons and NATO’s security policy – and this short paper asks whether the levels-of-analysis approach is still useful for explaining NATO’s security policy.
Studies on the mechanism of membrane fusion: evidence for an intermembrane calcium(2+) ion-phospholipid complex, synergism with magnesium(2+) ion, and inhibition by spectrin (1979)

The interaction of Ca2+ and Mg2+ with phosphatidylserine (PS) vesicles in 0.1 M NaCl aqueous solution was studied by equilibrium dialysis binding, X-ray diffraction, batch microcalorimetry, kinetics of cation-induced vesicle aggregation, release of vesicle contents, and fusion. Addition of either cation causes aggregation of PS vesicles and produces complexes with similar stoichiometry (1:2 cation/PS) at saturating concentrations, although the details of the interactions and the resulting complexes are quite different. Addition of Ca2+ to PS vesicles at T greater than or equal to 25 degrees C induces the formation of an "anhydrous" complex of closely apposed membranes with highly ordered crystalline acyl chains and a very high transition temperature (Tc greater than 100 degrees C). The formation of this complex is accompanied by a release of heat (5.5 kcal/mol), rapid release of vesicle contents, and fusion of the vesicles into larger membranous structures. By contrast, addition of Mg2+ produces a complex with PS which is much more hydrated, has no crystallization of the acyl chains at T greater than or equal to 20 degrees C, and has comparatively little fusion. Studies with both Ca2+ and Mg2+ added simultaneously indicate that there is a synergistic effect between the two cations, which results in an enhancement of the ability of Ca2+ to form its specific complex with PS at lower concentrations. The presence of the erythrocyte protein "spectrin" inhibits this synergism and interferes with the formation of the specific PS/Ca complex. It also inhibits the fusion of PS vesicles. It is proposed that the unique PS/Ca complex, which involves close apposition of vesicle membranes, is an intermembrane "trans" complex. We further propose that such a complex is a key step for the resultant phase transition and fusion of PS vesicles. By contrast, the PS/Mg complex is proposed to be a "cis" complex with respect to each membrane. The results are discussed in terms of the mechanism of membrane fusion.
On the fidelity of DNA polymerase α: the influence of α-thio dNTPs, Mn<sup>2+</sup>and mismatch repair (1985)

The phi X174am16 revertant system has been used to investigate the influence of alpha-thio-dNTPs and of Mn2+ on the fidelity of the 9S DNA polymerase alpha from calf thymus. Upon substituting dGTP by alpha-thio-dGTP during the in vitro replication, a nearly tenfold decrease in the frequency of G:G and G:T mispairs is observed. The formation of all other mispairs is not changed in the presence of the corresponding alpha-thio-dNTP. Mn2+ at concentrations of 0.5 mM does not influence the frequencies of the mispairs. The expression rate of errors formed during in vitro replication in the (-) strand has been determined for all mispairs detectable in the phi Xam16 system. The (-) strand expression of G:T, T:T and C:T mismatches is about 50%, whereas for A:G, G:G and C:A mismatches it is clearly below 50%. We conclude that the different base-base mismatches are repaired with different efficiencies.
The adverse effects of corticosteroids in central serous chorioretinopathy. (2003)

The purpose of this paper is to report on the possible deleterious effect of corticosteroids in central serous chorioretinopathy (CSCR). We will describe three patients in whom CSCR was induced or aggravated by corticosteroids. Despite multiple reports describing the onset of CSCR or aggravation of existing lesions with corticosteroids, they are still used by some ophthalmologists for the treatment of CSCR. Corticosteroids are also widely used for the treatment of a variety of diseases. Ophthalmologists should be aware that corticosteroids independently of the way of administration may cause this type of complication.

Energy efficient speculative threads (2010)

Thread-level parallelism at the chip level is critical in overcoming some of the challenges that have been ushered in through the advent of modern multicore processors (CMP). Extracting speculatively parallel threads from sequential applications and executing these threads on multicore processors is a promising technique to speed up these applications on multicore systems. However, the potential degradation in energy efficiency associated is an important factor that hinders the deployment of this technique. For multicore systems that integrate same-ISA heterogeneous cores, it is possible to judiciously allocate speculative threads to achieve energy-efficient performance improvement.
Impacts of S1 and X2 Interfaces on eMBMS Handover Failure: Solution and Performance Analysis (2018)

In evolved multimedia broadcast/multicast service (eMBMS), service continuity enables users move from one cell to another without interrupting eMBMS service. Unlike traditional handover in unicast transmission, an user equipment can receive eMBMS service in either unicast or multicast mode. In this paper, we point out a new handover failure problem in eMBMS due to the miss of rekeying information. We first take a close look at the new handover scenarios. We then investigate the problem by using comprehensive mathematical models. Our models provide insights on the new handover problem and introduce theoretical guidelines for mobile operators to design and optimize their networks without wide deployment to save cost and time. Moreover, we propose a solution to combat against the handover failure. Both the simulation and analytical results demonstrate that the impacts of the eMBMS handover failure are reduced significantly. In this paper, we present a systematic way to investigate the handover failure problem in eMBMS.
A deep learning approach to monitoring and detecting atrial fibrillation using wearable technology (2017)

Atrial Fibrillation (AF) is the most common cardiac arrhythmia in clinical practice, with a prevalence of 2% in the community. Not only it is associated with reduced quality of life, but also increased risk of stroke and myocardial infarction. Unfortunately, many cases of AF are clinically silent and undiagnosed, but long-term monitoring is difficult. Nonetheless, efforts at monitoring at-risk individuals and detecting clinically silent AF may yield significant public health benefit, as individuals with new-onset, asymptomatic AF would receive preventive therapies with anticoagulants and beta-blockers, for example. Wearables have enormous potential to provide low-risk and low-cost long-term monitoring of AF, but signals from such devices suffer from significant movement related noise that resembles AF. This work presents a robust approach to AF detection in a sequence of short windows with significant movement artifact. Pulsatile photoplethysmographic (PPG) data and triaxial accelerometry from 98 subjects (45 with AF and 53 with other rhythms) were captured using a multichannel wrist-worn device. A single channel electrocardiogram (ECG) was recorded (for rhythm verification only) simultaneously. A novel deep neural network approach to classify AF from wrist-worn PPG signals was developed on this data. A continuous wavelet transform was applied to the PPG data and a convolutional neural network (CNN) was trained on the derived spectrograms to detect AF. Combining the output of the CNN with features calculated based on beat-to-beat variability and signal quality provided a significant accuracy boost. Leave-one-out cross validation resulted in a pooled AUC of 0.95 (Accuracy=91.8%). The proposed approach resulted in a novel robust and accurate algorithm for detection of AF from PPG data, which is scalable and likely to improve in accuracy as the dataset size continues to expand.
THE COMPUTER GRAPHICS SCENE IN THE UNITED STATES (1984)

We briefly survey the major thrusts of computer graphics activities, examining trends and topics rather than offering a comprehensive survey of all that is happening. The directions of professional activities, hardware, software, and algorithms are outlined. Within hardware we examine workstations, personal graphics systems, high performance systems, and low level VLSI chips; within software, standards and interactive system design; within algorithms, visible surface rendering and shading, three-dimensional modeling techniques, and animation.
Fabrication of Ultrafine Conducting Polymer and Graphite Nanoparticles (2002)

Graphite nanoparticles, with diameters as small as 2 nm (see picture) can be fabricated by the carbonization of polypyrrole nanoparticles of similar dimensions, which have been prepared by a low-temperature polymerization technique in which a micellar microemulsion acts as a “nanoreactor”. The graphite nanoparticles exhibit excellent transparent conductive performance in a polycarbonate medium, and may be envisaged as a substitute for carbon nanotubes.
뷔히너의 데카르트 I - 근대적 자아의 자기경험의 형식 (2017)

Die Literatur von Buchner, die zu der Goethezeit gehort und zugleich darin eine eigentumliche Position einnimmt, ist in all seinen Lebensphasen mit den politischen, philosophischen und naturwissenschaftlichen Ideen ausgefullt. Nach den neuesten Buchnerforschungen kann man sagen, dass er schon Anfang des neunzehnten Jahrhunderts nicht nur zur Ausbildung des musterhaften Beispiels der literarischen Anthropologie, sondern auch zur Gestaltung der transdisziplinaren Perspektive der Geistes- und Naturwissenschaften beigetragen hat, uber die man erst seit Mitte des zwanzigsten Jahrhunderts zu diskutieren angefangen hat.Im Hinblick darauf, Politik, Philosophie, Naturwissenschaft und Literatur miteinander vereinheitlicht zu gestalten, hat Buchner versucht, eine denen gemeinsame Denkweise herauszuarbeiten. Vor allem wollte er zwei Schranken, die vor ihm gestanden waren, uberschreiten. Die eine war die holistische Teleologie von Hegel, die idealistisch getont ist, und die andere der sensualistische Solipsismus, der nur auf die experimentalen und analytischen Naturverstandnisse orientiert ist. In der Mitte der Suche Buchners nach dem neuen Paradigma ist die genetische Methode als eine entscheidende Vermittlung des Paradigmenwechsels platziert. Diese Methode, die sich schon in seiner Doktorarbeit, Memoire sur le systeme nerveux du barbeau, geausert hat und im ahnlichen Zusammenhang mit dem Kontext von der romantischen Naturphilosophie und -wissenschaften, zu dem die Metamorphosenlehre Goethes, die genetische Naturgeschichte Herders, Schellings genetische Philosophie und Okens genetische Methode gehoren, gestanden ist, hat in der nachidealistischen Zeit eine wichtige Rolle als ein Antriebswerk zum neuen Paradigma gespielt.Ein Kernpunkt inmitten des komplexen Problembewusstseins Buchners, das von den spannenden Wechselwirkungen zwischen den Denk- und Handlungsmodi konstituiert ist, war ein Herausfinden einer Form der stabilen Denkweise, mit der das moderne Ich sich selbst als ein autonomes Subjekt neu erfinden kann. Der Versuch, diese Form finden zu wollen, zeigt sich fragmentarisch in seinen literarischen Werken, aber am deutlichsten in seiner philosophischen Studie zu Descartes. Daher zielt die vorliegende Arbeit darauf ab, die in den Schriften Buchners auftauchende Form der Selbsterfahrung des modernen Ichs herauszuarbeiten, indem sie das, was er durch die Rekonstruktion der cartesianischen Philosophie gemeint hat, wieder filigran rekonstruiert.
