A hypervideo system generator (1997)

In the past, a number of approaches have been proposed for the modeling and implementation of hypermedia and multimedia systems. However, automatic implementation is still lacking with regard to setting up various hypervideo systems. This paper proposes a hypervideo system generator for automatic implementation of various hypervideo systems. The proposed system is established by using a Generalized HyperVideo System (GHVS) model. A HyperVideo Linking Generator (HVLG) is introduced to on-line authoring of a GHVS program for specifying a hypervideo system. A HyperVideo Browser System (HVBS) has been developed for navigating various hypervideo systems. The proposed hypervideo generator has been established on Windows 3.1 and Windows 95, in which several other educational hypervideo applications have been successfully developed. Moreover, with the help of this prototype, the development time to build such hypervideo applications is considerably reduced when compared with the development of the same application using existing programming languages. © 1997 John Wiley & Sons, Ltd.
Inhibition of Human and Rat Platelet Aggregation by Extracts of Mo-er (Auricularia auricula) (1982)

Hot water extracts of Mo-er (1 gm by 15 ml of water), an oriental food (Auricularia auricula), inhibit strongly both human and rat platelet ADP-induced aggregation. HPLC analysis of two varieties of Mo-er, A. auricula and A. polytricha (a black tree fungus), shows that they contain adenosine (Ado), 133 and 154 micrograms per gram of dry fungus, respectively. The inhibition of ADP-induced platelet aggregation by Mo-er extracts and by Ado was compared. Mo-er extracts caused a more rapid onset and a longer duration of inhibition that produced by equivalent amounts of Ado. Furthermore, Mo-er extract treated with adenosine deaminase to degrade the Ado retained the capacity to inhibit platelet aggregation. The inhibitory effects of Mo-er extracts of ADP-induced human platelet aggregation are greatly potentiated by the inhibitors of cyclic AMP phosphodiesterase such as oxagrelate (phthalazinol) and papaverine. The inhibition of platelet aggregation is only partially blocked by 2',5'-dideoxy-adenosine (DDA), an inhibitor of platelet adenylate cyclase and 5'-deoxy, 5'-methylthioadenosine (MTA), an antagonist of ADO receptors. ADP-induced rat platelet aggregation is strongly inhibited by Mo-er extracts, but not by Ado. This inhibition is not reversed by either DDA or MTA. These findings indicate that Mo-er extracts contain an agent (or agents) in addition to Ado, that blocks platelet aggregation by a mechanism that does not involve the platelet cyclic AMP system.

A biosseguranca envolve praticas preventivas contra agentes patogenicos, quimicos, fisicos e radioativos, visando a saude do homem e dos animais, a preservacao do meio ambiente e a qualidade dos resultados. Com isso, vemos que os laboratorios de quimica sao lugares que apresentam alto potencial de acidentes, pela especificidade do trabalho que pressupoe a presenca de diversas substâncias letais, toxicas, corrosivas e irritantes, inflamaveis ou instaveis e pela utilizacao de aparelhos. Nessa perspectiva este trabalho avaliou o grau de importância da biosseguranca na visao dos alunos do Curso de Licenciatura em Quimica do Centro de Educacao, Ciencia e Tecnologias dos Inhamuns – CECITEC-UECE, Taua-CE. Os dados foram coletados atraves de um questionario contendo 15 questoes e aplicado a cinquenta alunos de todos os semestres do curso de licenciatura em quimica. Os resultados revelaram que 54% dos estudantes eram do sexo masculino e 46% do sexo feminino. A maioria desses estudantes demonstrou nao ter conhecimentos sobre as normas de biosseguranca (64%) e a utilizacao de equipamentos de protecao individual (EPIs) (50%). Com a analise dos resultados pode-se constatar que pesquisas sobre a biosseguranca sao de extrema necessidade para prevenir e manter os estudantes de quimica informados contra riscos futuros inerentes ao exercicio de atividades laboratoriais contribuindo assim para sua formacao.
Waves of acoustically induced transparency in bubbly liquids: Theory and experiment (2013)

The theory of self-organization of bubbles in acoustic fields predicts formation and propagation of waves of self-induced acoustic transparency. This is a strongly nonlinear effect, which is a result of a two-way coupling of the sound field with the bubble distribution. We are challenging the theory with an experiment. Here, a homogeneous distribution of gas bubbles is first generated and then an ultrasonic field is switched on. The pressure waves are below the cavitation threshold and in a frequency range from 50 kHz to 200 kHz, mostly above the linear resonance frequency of the bubbles. The ultrasound leads to a rapidly propagating bubble wave away from the transducer. The dynamics is observed with a high-speed camera and analyzed. Interestingly, this transparent region is propagating through the bubbly liquid at velocities substantially higher than the bubble rise velocity due to the gravity. A simplified theoretical model of this acoustically induced transparency is developed. Both, analytical and numerical solutions are obtained. A comparison of the experimental data with the model is presented and the underlying physics of the problem is discussed.
A study of end-to-end web access failures (2006)

We present a study of end-to-end web access failures in the Internet. Part of our characterization of failures is based on directly observable end-to-end information. We also present novel analyses that reveal aspects of end-to-end failures that would be hard to discern otherwise. First, we combine end-to-end failure observations across a large number of clients to classify failures as server-related or client-related. Second, we correlate failures attributed to a client or server with BGP churn for the corresponding IP address prefix(es), to shed light on the end-to-end impact of BGP instability.

Parkinsonian signs in patients with cervical dystonia treated with pallidal deep brain stimulation (2018)

Pallidal deep brain stimulation is an established treatment in patients with dystonia. However, evidence from case series or uncontrolled studies suggests that it may lead in some patients to specific parkinsonian symptoms such as freezing of gait, micrographia, and bradykinesia. We investigated parkinsonian signs using the Movement Disorder Society Unified Parkinson's Disease Rating Scale motor score by means of observer-blinded video ratings in a group of 29 patients treated with pallidal stimulation and a non-surgical control group of 22 patients, both with predominant cervical dystonia. Additional assessments included MRI-based models of volume of neural tissue activated to investigate areas of stimulation related to dystonic symptom control and those likely to induce parkinsonian signs as well as an EMG analysis to investigate functional vicinity of stimulation fields to the pyramidal tract. Compared with controls, stimulated patients had significantly higher motor scores (median, 25th-75th percentile: 14.0, 8.0-19.5 versus 3.0, 2.0-8.0; P < 0.0001), as well as bradykinesia (8.0, 6.0-14.0 versus 2.0, 0.0-3.0; P < 0.0001) and axial motor subscores (2.0, 1.0-4.0 versus 0.0, 0.0-1.0; P = 0.0002), while rigidity and tremor subscores were not different between groups. Parkinsonian signs were partially reversible upon switching stimulation off for a median of 90 min in a subset of 19 patients tolerating this condition. Furthermore, the stimulation group reported more features of freezing of gait on a questionnaire basis. Quality of life was better in stimulated patients compared with control patients, but parkinsonian signs were negatively associated with quality of life. In the descriptive imaging analysis maximum efficacy for dystonia improvement projected to the posteroventrolateral internal pallidum with overlapping clusters driving severity of bradykinesia and axial motor symptoms. The severities of parkinsonian signs were not correlated with functional vicinity to the pyramidal tract as assessed by EMG. In conclusion, parkinsonian signs, particularly bradykinesia and axial motor signs, due to pallidal stimulation in dystonic patients are frequent and negatively impact on motor functioning and quality of life. Therefore, patients with pallidal stimulation should be monitored closely for such signs both in clinical routine and future clinical trials. Spread of current outside the internal pallidum is an unlikely explanation for this phenomenon, which seems to be caused by stimulation of neural elements within the stimulation target volume.
Nitrosopumilus maritimus gen. nov., sp. nov., Nitrosopumilus cobalaminigenes sp. nov., Nitrosopumilus oxyclinae sp. nov., and Nitrosopumilus ureiphilus sp. nov., four marine ammonia-oxidizing archaea of the phylum Thaumarchaeota (2017)

Four mesophilic, neutrophilic, and aerobic marine ammonia-oxidizing archaea, designated strains SCM1<sup>T</sup>, HCA1<sup>T</sup>, HCE1<sup>T</sup> and PS0<sup>T</sup>, were isolated from a tropical marine fish tank, dimly lit deep coastal waters, the lower euphotic zone of coastal waters, and near-surface sediment in the Puget Sound estuary, respectively. Cells are straight or slightly curved small rods, 0.15-0.26 µm in diameter and 0.50-1.59 µm in length. Motility was not observed, although strain PS0<sup>T</sup> possesses genes associated with archaeal flagella and chemotaxis, suggesting it may be motile under some conditions. Cell membranes consist of glycerol dibiphytanyl glycerol tetraether (GDGT) lipids, with crenarchaeol as the major component. Strain SCM1<sup>T</sup> displays a single surface layer (S-layer) with p6 symmetry, distinct from the p3-S-layer reported for the soil ammonia-oxidizing archaeon Nitrososphaera viennensis EN76<sup>T</sup>. Respiratory quinones consist of fully saturated and monounsaturated menaquinones with 6 isoprenoid units in the side chain. Cells obtain energy from ammonia oxidation and use carbon dioxide as carbon source; addition of an α-keto acid (α-ketoglutaric acid) was necessary to sustain growth of strains HCA1<sup>T</sup>, HCE1<sup>T</sup>, and PS0<sup>T</sup>. Strain PS0<sup>T</sup> uses urea as a source of ammonia for energy production and growth. All strains synthesize vitamin B1 (thiamine), B2 (riboflavin), B6 (pyridoxine), and B12 (cobalamin). Optimal growth occurs between 25 and 32 °C, between pH 6.8 and 7.3, and between 25 and 37 ‰ salinity. All strains have a low mol% G+C content of 33.0-34.2. Strains are related by 98 % or greater 16S rRNA gene sequence identity, sharing ~85 % 16S rRNA gene sequence identity with Nitrososphaera viennensis EN76<sup>T</sup>. All four isolates are well separated by phenotypic and genotypic characteristics and are here assigned to distinct species within the genus Nitrosopumilus gen. nov. Isolates SCM1<sup>T</sup> (=ATCC TSD-97<sup>T</sup> =NCIMB 15022<sup>T</sup>), HCA1<sup>T</sup> (=ATCC TSD-96<sup>T</sup>), HCE1<sup>T</sup> (=ATCC TSD-98<sup>T</sup>), and PS0<sup>T</sup> (=ATCC TSD-99<sup>T</sup>) are type strains of the species Nitrosopumilusmaritimus sp. nov., Nitrosopumilus cobalaminigenes sp. nov., Nitrosopumilus oxyclinae sp. nov., and Nitrosopumilus ureiphilus sp. nov., respectively. In addition, we propose the family Nitrosopumilaceae fam. nov. and the order Nitrosopumilales ord. nov. within the class Nitrososphaeria.
Metal Ion Implantation for the Fabrication of Stretchable Electrodes on Elastomers (2008)

Abstract Here, the use of low‐energy metal ion implantation by filtered cathodic vacuum arc to create highly deformable electrodes on polydimethylsiloxane (PDMS) membranes is reported. Implantation leads to the creation of nanometer‐size clusters in the first 50 nm below the surface. When the elastomer is stretched, these small clusters can move relative to one another, maintaining electrical conduction at strains of up to 175%. Sheet resistance versus ion dose, resistance versus strain, time stability of the resistance, and the impact of implantation on the elastomer's Young's modulus are investigated for gold, palladium, and titanium implantations. Of the three tested metals, gold has the best performance, combining low and stable surface resistance, very high strain capabilities before loss of electrical conduction, and low impact on the Young's modulus of the PDMS membrane. These electrodes are cyclically strained to 30% for more than 10 5 cycles and remain conductive. In contrast, sputtered or evaporate metals films cease to conduct at strains of order 3%. Additionally, metal ion implantation allows for creating semi‐transparent electrodes. The optical transmission through 25‐µm‐thick PDMS membranes decreases from 90% to 60% for Pd implantations at doses used to make stretchable electrodes. The implantation technique presented here allows the rapid production of reliable stretchable electrodes for a number of applications, including dielectric elastomer actuators and foldable or rollable electronics.
Replacement of Diseased Mouse Liver by Hepatic Cell Transplantation (1994)

Adult liver has the unusual ability to fully regenerate after injury. Although regeneration is accomplished by the division of mature hepatocytes, the replicative potential of these cells is unknown. Here, the replicative capacity of adult liver cells and their medical usefulness as donor cells for transplantation were investigated by transfer of adult mouse liver cells into transgenic mice that display an endogenous defect in hepatic growth potential and function. The transplanted liver cell populations replaced up to 80 percent of the diseased recipient liver. These findings demonstrate the enormous growth potential of adult hepatocytes, indicating the feasibility of liver cell transplantation as a method to replace lost or diseased hepatic parenchyma.
B cell development arrest upon insertion of a neo gene between JH and Emu: promoter competition results in transcriptional silencing of germline JH and complete VDJ rearrangements. (2002)

Previous targeting experiments within the IgH locus have shown that V(D)J recombination was affected by an insertion of a neo gene within E(mu) upstream of the core enhancer, but not by insertions downstream of the enhancer. Similarly, class switch recombination to a given (C) gene was affected only by interposition of neo in between that gene and the 3' IgH enhancers. Here we show that insertion of neo upstream E(mu) only marginally impairs V(D)J recombination, but results in an altered D and J(H) gene usage and completely blocks transcription of the germline J(H) region and the rearranged VDJ segments. Although transcriptional silencing of J(H) occurs upstream of the insertion and results in the lack of mature B cells in homozygous mutant animals, IgH transcription is maintained downstream of the insertion together with neo transcription and can be up-regulated by LPS stimulation or upon fusion with plasmacytoma cells. Altogether these data argue for a polarized "neo effect" involving promoter competition and further show that V(D)J rearrangement can be uncoupled from transcription.
Seismic body and surface wave data integration for near surfacecharacterisation (2010)

Seismic methods are widely used in near surface characterisation and very often different seismic datasets relative to body and surface waves are acquired at the same site. These data are, in the majority of the cases, acquired and interpreted separately to provide different information disregarding the synergies between different methods both in acquisition and inversion. In particular the joint or constrained inversion of different datasets may overcome intrinsic limitations of individual techniques and provide a more reliable and consistent final velocity model. Moreover, different information coming from different datasets provide a comprehensive site characterisation.
Flumazenil therapy for hepatic encephalopathy in cirrhotic patients: a double-blind pragmatic randomized, placebo study. (1995)

Standard Recovery Method to Rendezvous Approach Trajectory. (2002)

Rendezvous docking technology will be necessary for advanced space activities in the early 21st century, such as logistic support service to the International Space Station, exchange of observation sensors or bus equipments, re-supply of fuel or cryogenic liquid, etc. A chaser vehicle will perform rendezvous along a reference trajectory, which would be pre-planned and well investigated. If the chaser deviate from the reference trajectory for instance because of thruster trouble, it will be required to recover to the reference trajectory as soon as possible. In this paper, we introduce an easy and practical recovery method based on C–W solution of Hill’s equation. We think the recovery method will be applicable for many kinds of rendezvous vehicles.
Principles of Cortical Processing Applied to and Motivated by Artificial Object Recognition (2000)

It is an assumption of the neural computation community that the brain as the most successful pattern recognition system is a useful model for deriving efficient algorithms on computers. But how can a useful interaction between brain research and artificial object recognition be realized? We see two questionable ways of interaction. On the one hand, a very detailed modelling of biological networks may lead to a disregard of the task solved in the brain area being modelled. On the other hand, the neural network community may lose credibility by a very rough simplification of functional entities of brain processing. This may result in a questionable naming of simple functional entities as neurons or layers to pretend biological plausibility. In our view, it is important to understand the brain as a tool solving a certain task and therefore it is important to understand the functional meaning of principles of cortical processing, such as hierarchical processing, sparse coding, and ordered arrangement of features. Some researchers (e.g., Barlow, 1961c; Palm, 1980; Földiák, 1990; Atick, 1992b; Olshausen and Field, 1997) have already made important steps in this direction. They have given an interpretation of some of the above-mentioned principles in terms of information theory. Others (e.g. Hummel and Biederman, 1992; Lades et al., 1992) have tried to initiate an interaction between brain research and artificial object recognition by building efficient and biologically motivated object recognition systems. Following these two lines of research, we suggest to look at a functional level of biological processing and to utilize abstract principles of cortical processing in an artificial object recognition system.

Demonstration in Space of a Smart Hyperspectral Imager for Nanosatellites (2018)

HyperScout is the first smart hyperspectral imager for nanosatellites. It has been launched on the 2nd of February 2018 at 8:51 CET, from the Jiuquan Satellite Launch Center in China. The launch vehicle Long March 2D lifted off on schedule and the satellite was separated from the launch vehicle minutes later. Approximately after 6 hours the first contact was established by GomSpace in Aalborg, Denmark. HyperScout is based on a long line of development led by cosine. The project to develop, build and launch the first HyperScout was funded by ESA, with support from the Dutch, Belgian and Norwegian national space organizations: Netherlands Space Office, BELSPO and Norsk Romsenter. cosine, as the prime contractor, enlisted the help of consortium partners S&T, TU Delft, VDL and VITO. The applications for which HyperScout has been conceived for are crop water management, fire hazard monitoring, flood detection, change detection of land use and land coverage and vegetation monitoring. The aim of the demonstration mission is to assess the quality of the data that will be acquired and the consequent suitability for the intended applications. Furthermore, the basic functionalities of the instrument as well as the onboard processing in real time will be demonstrated. The demonstration is divided in three operational blocks, during which HyperScout will be operated to acquire data from invariant sites for vicarious calibration, from application sites to qualify HyperScout for all the applications it has been conceived for, and to perform software experiments to demonstrate the novel approach to overcome the bandwidth limitation on small platforms. This paper reports about the outcome of the operations performed so far in orbit, and about the preliminary results obtained from the data evaluation performed during the demonstration project.
Transient thermoelastic analysis of FGM rotating thick cylindrical pressure vessels under arbitrary boundary and initial conditions (2017)

Assuming arbitrary boundary and initial conditions, a transient thermo-elastic analysis of a rotating thick cylindrical pressure vessel made of functionally graded material (FGM) subjected to axisymmetric mechanical and transient thermal loads is presented. Time-dependent thermal and mechanical boundary conditions are assumed to act on the boundaries of the vessel. Material properties of the vessel are assumed to be graded in the radial direction according to a power law function. The Poisson’s ratio is assumed to be constant. Method of separation of variables has been used to analytically calculate the time dependent temperature distribution as a function of radial direction. In a case study, the distribution of radial and hoop stresses along the thickness is derived and plotted. In order to validate the model, the analytical results have been compared with finite element method modeling results presented in literature. Any arbitrary boundary and initial conditions can be handled using the equations derived in the present research. In order to investigate the inhomogeneity effect on time dependent stress distribution and displacements, values of the parameters have been set arbitrary in the present study. To the best of the authors’ knowledge, in previous researches, transient thermo-elastic analysis of thick cylindrical FGM pressure vessels is investigated by numerical methods, while in the present research, an exact solution is derived for the same problem.
