TinLizzieWysiWiki andWikiPhone: Alternative approaches to asynchronous and synchronous collaboration on the Web (2007)

This paper presents TinLizzie WysiWiki and WikiPhone, two systems which explore new approaches to media-rich end-user collaboration on the World Wide Web. TinLizzie WysiWiki enables authoring of interactive, media-rich documents, containing graphical objects bearing user-defined scripts, on the Web. In TinLizzie WysiWiki, a user manipulates text and active objects in a WYSIWYG graphical editor in a manner similar to Squeak eToys. A notable aspect of TinLizzie WysiWiki is that it allows both synchronous and asynchronous collaboration among multiple users. In asynchronous collaboration, the user content is saved in a common format and posted on the Web. Later, another user can visit and update the document on the server. In synchronous collaboration, more than one user can share a document and edit it simultaneously and collaboratively in real-time. The second system presented is called WikiPhone. WikiPhone is a minimalist voice over IP (VoIP) system which uses only HTTP. WikiPhone allows multiple users to talk to each other using a web browser. WikiPhone's strength is its simplicity in terms both of the user experience and of its implementation. The user simply points a Web-browser to a URL, and then directly participates in a conversation, or listens to ongoing conversations among others. In the implementation, it seeks the simplest possible approach, yet provides a usable VoIP system. Both systems still require a small, portable Web browser plugin, but otherwise they stay within the artificial limitations of today's World Wide Web. The authors think that they exhibit possible future directions for collaboration on the Web.
Une approche structurelle et comportementale de modélisation pour la vérification de composants VLSI (1995)

The manuscript describes a modeling and validation methodology for the design of microprogrammed circuits that implement network communication protocols. The method was developped in the framework of the FICOMP project, which implement the FIELDBUS protocol standard. The first chapter describes the industrial context of the project, the various specification levels for the circuit, and the simulation and verification tools at hand. Chapter two presents the VOVHDL langage, an extension of VHDL for the specification of communication and synchronisations among concurrent processes ; a synchronous semantics in terms of labeled transitions systems is given for VOVHDL. Chapter three presents a modeling approach for hierarchical VOVHDL descriptions, and shows its application to the FICOMP circuit : internal modules are interconnected with a communication module to build a higher level module; this model is then translated into the input format of the ASA+ verification software. Chapter four recalls the essential features of VHDL and formalize its simulation semantics in terms of labeled transition systems. The application of the methodology to the specification of two modules of the FICOMP circuit, and their translation into the proposed model, are detailed in the appendices.
An update of Coenzyme Q<sub>10</sub> implications in male infertility: Biochemical and therapeutic aspects (2005)

This review is focused upon the role of coenzyme Q(10) in male infertility in the light of a broader issue of oxidative damage and antioxidant defence in sperm cells and seminal plasma. Reactive oxygen species play a key pathogenetic role in male infertility besides having a well-recognized physiological function. The deep involvement of coenzyme Q(10) in mitochondrial bioenergetics and its antioxidant properties are at the basis of its role in seminal fluid. Following the early studies addressing its presence in sperm cells and seminal plasma, the relative distribution of the quinone between these two compartments was studied in infertile men, with special attention to varicocele. The reduction state of CoQ(10) in seminal fluid was also investigated. After the first in vitro experiments CoQ(10) was administered to a group of idiopathic asthenozoospermic infertile patients. Seminal analysis showed a significant increase of CoQ(10) both in seminal plasma and in sperm cells, together with an improvement in sperm motility. The increased concentration of CoQ(10) in seminal plasma and sperm cells, the improvement of semen kinetic features after treatment, and the evidence of a direct correlation between CoQ(10) concentrations and sperm motility strongly support a cause/effect relationship. From a general point of view, a deeper knowledge of these molecular mechanisms could lead to a new insight into the so-called unexplained infertility.
Automation solutions for the evaluation of plant health in corn fields (2015)

The continuously growing need for increasing the production of food and reducing the degradation of water supplies, has led to the development of several precision agriculture systems over the past decade so as to meet the needs of modern societies. The present study describes a methodology for the detection and characterization of Nitrogen (N) deficiencies in corn fields. Current methods of field surveillance are either completed manually or with the assistance of satellite imaging, which offer infrequent and costly information to the farmers about the state of their fields. The proposed methodology promotes the use of small-scale Unmanned Aerial Vehicles (UAVs) and Computer Vision algorithms that operate with information in the visual (RGB) spectrum. Through this implementation, a lower cost solution for identifying N deficiencies is promoted. We provide extensive results on the use of commercial RGB sensors for delivering the essential information to farmers regarding the condition of their field, targeting the reduction of N fertilizers and the increase of the crop performance. Data is first collected by a UAV that hovers over a stressed area and collects high resolution RGB images at a low altitude. A recommendation algorithm identifies potential segments of the images that are candidates exhibiting N deficiency. Based on the feedback from experts in the area a training set is constructed utilizing the initial suggestions of the recommendation algorithm. Supervised learning methods are then used to characterize crop leaves that exhibit signs of N deficiency. The performance of 84.2% strongly supports the potential of this scheme to identify N-deficient leaves even in the case of images where the unhealthy leaves are heavily occluded by other healthy or stressed leaves.
Pervasive surveillance using a cooperative mobile sensor network (2006)

A distributed processing and communication approach is applied to networked surveillance systems providing an extended perception and sensing capability in monitored environments. By pervasive we mean that the entire surveyed area is covered by a heterogeneous collection of fixed and mobile sensors. The sensor network uses a cooperative tracking technique that allows for the deployment of mobile sensors based on data provided by other sensors in the network. Also, an image-based tracking technique is used for tracking when the target is in view. The task of tracking multiple targets in a distributed surveillance network is a challenging problem because of the following reasons: (1) multiple targets need to be monitored and tracked continuously and must remain in view of at least one of the sensors; (2) the view of the sensors needs to be optimized so that the targets are observed with a discernible resolution for feature identification; (3) it is important to devise stable control algorithms for accomplishing the surveillance task; (4) assigning tracking tasks to sensors must consider load balancing and efficient use of all sensors. This paper presents a distributed communication and processing model that allows for a fast deployment of sensor nodes and implementation of ad hoc tracking in a multi-target surveillance scenario. Also, experimental results demonstrate the efficacy of the proposed approach for tracking multiple targets over a large area with fixed and mobile sensors
Endothelium-dependent changes in retinal blood flow following ischemia (1998)

These findings indicate that (1) constriction by endothelin, together with a loss of nitric oxide's tonic dilatative effect, contributes importantly to mediating postischemic hypoperfusion in retina; (2) improvements in retinal perfusion can be realized with endothelin receptor blockade or potentiation of extracellular adenosine; and (3) additional reductions in postischemic RBF can occur in response to resuscitation with 100% oxygen because retinal microcirculatory reactivity to hyperoxia remains intact during the hypoperfusion period.
Point-based modeling, animation, and simulation system for computer graphics (2006)

As 3D digital photographic and scanning devices produce higher resolution images, acquired geometric data sets grow more complex in terms of the modeled objects' size, geometry, and topology. As a consequence, point-sampled geometry is becoming ubiquitous in graphics and geometric information processing, and poses new challenges which have not been fully resolved by the state-of-art graphical techniques. 
In this dissertation, we address the challenges by proposing a novel framework for dynamic shape modeling, physical animation, and scientific simulation of point-sampled geometry. We developed the Point-based Modeling, Animation, and Simulation System, or P-MASS, for any scanned point geometry, without the need of converting them to polygonal meshes or higher order spline representations. 
This dissertation follows our development of the P-MASS framework. First, we propose to combine point-based geometry with implicit surface representation and integrate the mass-spring-based dynamic implicit volumetric model with the point-based geometry, in order to introduce physics-based modeling and haptics interface to the sculpting and deformation of point set surfaces. We further incorporate scalar-field guided free-form deformation (FFD) into our surface deformation system to further expand local and global surface editing functionality. In addition to the implicit surface approach, we systematically develop a global conformal parameterization method for point-sampled surfaces, which can serve as a foundation for many other graphics applications, such as physical simulation, shape registration, morphing, attribute transfer, and spline surface fitting of point set surfaces, etc. Finally, we develop a meshless computational framework to simulate the elastic deformation and crack propagation of the underlying point-based surface and volumetric physical model. 
Our P-MASS framework aims to bridge the gap between the point-sampled geometry with, physics-based modeling governed by partial differential equations. We have employed our methodologies in a wide variety of applications, including surface editing, reverse engineering and model restoration, solid modeling and simulation, attribute transfer and morphing, thin-shell elastic and fracture simulation, haptic rendering, etc. We describe these applications in detail and outline implementation issues pertaining to our framework.
Localization of cells synthesizing transforming growth factor-alpha mRNA in the mouse brain (1988)

The distribution of transforming growth factor (TGF)-alpha and TGF-beta 1 mRNA containing cells in adult mouse brain was examined using in situ hybridization histochemistry. There were no detectable TGF-beta 1 mRNA-containing cells found in the brain. TGF-alpha mRNA was localized to cell bodies of the caudate nucleus, dentate gyrus, anterior olfactory nuclei, and a laminar distribution of mitral cells in the olfactory bulb. TGF-alpha-synthesizing cells were localized in brain regions that have been shown to synthesize nerve growth factor, epidermal growth factor (EGF) and enkephalins. The function of local synthesis of TGF-alpha in the brain is as yet unknown.

The nutritive value of normal and brown midrib-3 maize (1984)

Summary Normal and brown midrib-3 (bm 3 ) maize plants of three genotypes (Inra 188, Inra 240 and Inra 258) were sampled at three stages of maturity. Whole crop and plant components were analysed for in vitro digestible organic matter in the dry matter (DOMD) and the concentration of neutral detergent fibre, cellulose, hemicellulose, xylose, soluble sugars, starch and total nitrogen in the dry matter. The concentrations of total nitrogen, neutral detergent fibre, cellulose, hemicellulose and xylose were similar in both normal and bm 3 plants. Xylose was the main constituent sugar of hemicellulose forming 70–75% of the total hemicellulose. The higher concentration of soluble sugars and lower concentration of starch in the bm 3 plants was attributed to the later maturity of the bm 3 plants. The bm 3 gene significantly reduced lignin synthesis in the whole plant and plant components at all harvests. The mean concentration of lignin in the normal and bm 3 plants were 2·2 and 1·4%, respectively. The ferulic and p-coumaric acid concentrations in the bm 3 plants were 1·31 and 0·93 mg/g D.M. compared with 1·59 and 1·16 mg/g D.M. for the normal plants, respectively. The in vitro DOMD values for the bm 3 plants were significantly higher (P < 0.05) than their normal counterparts.

An active model-based algorithm for correspondence and estimation of pose parameters of objects (2002)

A method of actively corresponding a model with an image and estimating pose parameters is proposed. The algorithm used follows hints from human visual recognition processes, widely believed to be efficient and adaptive. It introduces into typical bottom-up information extraction procedures several top-down information processing ones; these latter are usually effective and robust. The combination of such procedures that form our "active model based algorithm" makes the whole process more effective. The system is robust because of the high level influence on the low level image processing. Experimental results show the parameters obtained are precise enough for robot gesture estimation, navigation and obstacle avoidance.
Silencing the Olfactory Co-Receptor RferOrco Reduces the Response to Pheromones in the Red Palm Weevil, Rhynchophorus ferrugineus (2016)

The red palm weevil (RPW, Rhynchophorus ferrugineus), one of the most widespread of all invasive insect pest species, is a major cause of severe damage to economically important palm trees. RPW exhibits behaviors very similar to those of its sympatric species, the Asian palm weevil (R. vulneratus), which is restricted geographically to the southern part of Southeast Asia. Although efficient and sustainable control of these pests remains challenging, olfactory-system disruption has been proposed as a promising approach for controlling palm weevils. Here, we report the cloning and sequencing of an olfactory co-receptor (Orco) from R. ferrugineus (RferOrco) and R. vulneratus (RvulOrco) and examine the effects of RferOrco silencing (RNAi) on odorant detection. RferOrco and RvulOrco encoding 482 amino acids showing 99.58% identity. The injection of double-stranded RNA (dsRNA) from RferOrco into R. ferrugineus pupae significantly reduced RferOrco gene expression and led to the failure of odor-stimulus detection, as confirmed through olfactometer and electroantennography (EAG) assays. These results suggest that olfactory-system disruption leading to reduced pheromone detection holds great potential for RPW pest-control strategies.
Persius 1. 107–10 (1958)

Persius places these words in the mouth of his interlocutor, who states one of the traditional arguments against satire in the contrived manner typical of our poet. The passage may be translated: ‘What need is there to rasp upon tender little ears with biting truth? Be careful that the thresholds of the great do not perhaps grow cold towards you; here there is the nasal sound of the canine letter.’
Elevated Arsenic and Uranium Concentrations in Unregulated Water Sources on the Navajo Nation, USA (2016)

Regional water pollution and use of unregulated water sources can be an important mixed metals exposure pathway for rural populations located in areas with limited water infrastructure and an extensive mining history. Using censored data analysis and mapping techniques we analyzed the joint geospatial distribution of arsenic and uranium in unregulated water sources throughout the Navajo Nation, where over 500 abandoned uranium mine sites are located in the rural southwestern United States. Results indicated that arsenic and uranium concentrations exceeded national drinking water standards in 15.1 % (arsenic) and 12.8 % (uranium) of tested water sources. Unregulated sources in close proximity (i.e., within 6 km) to abandoned uranium mines yielded significantly higher concentrations of arsenic or uranium than more distant sources. The demonstrated regional trends for potential co-exposure to these chemicals have implications for public policy and future research. Specifically, to generate solutions that reduce human exposure to water pollution from unregulated sources in rural areas, the potential for co-exposure to arsenic and uranium requires expanded documentation and examination. Recommendations for prioritizing policy and research decisions related to the documentation of existing health exposures and risk reduction strategies are also provided.
Spectroscopic characteristics of Sm 3+ doped alkaline earth potassium titanium phosphate glasses (2009)

The paper reports on the preparation and characterization of Sm 3+ doped alkaline earth potassium titanium phosphate (RKTP) glasses with molar composition of 24(NaPO 3 ) 6 + 30KH 2 PO 4 + 25TiO 2 + 20RCl 2 + 1Sm 2 O 3 (R=Mg, Ca & Sr). Optical absorption spectra in the UV-VIS-NIR region reveal twelve absorption bands and are assigned to different transitions arising from the 6 H 5/2 ground state. The energy level structure of Sm 3+ (4f 5 ) has been analyzed using the free-ion Hamiltonian model. The root mean square deviations between the experimental and calculated energies of Sm 3+ doped MgKTP, CaKTP and SrKTP glasses are 44, 35 and 56 cm -1 respectively and are comparable with the earlier reports. By measuring the areas under the absorption peaks, the experimental oscillator strengths are calculated and the phenomenological JO-intensity parameters (Ω 2 , Ω 4 and Ω 6 ) have been determined with the help of least-squares fitting approach. These parameters exhibit a similar trend as Ω 2 >Ω 6 >Ω 4 in all the three glasses. The evaluated JO parameters are then used to calculate the excited 4 G 5/2 level radiative properties such as radiative transition probabilities (A R ), branching ratios (β R ) and lifetimes (τ R ). The emission spectra recorded by exciting with 476 nm shows four peaks at 563, 599, 649 and 714 nm and are assigned to 4 G 5/2 → 6 H 5/2 , 6 H 7/2 , 6 H 9/2 , 6 H 11/2 respectively. The experimentally observed decay profiles of the 4 F 5/2 level of Sm 3+ are found to be single exponential yielding the lifetimes (τ mes ) 2330, 1750 and 2320 μs in MgKTP, CaKTP and SrKTP glasses respectively, which are comparable with the calculated lifetimes (τ R ) obtained from the Judd-Ofelt theory.

[Asthma and scuba diving Absolute contraindication? in all asthma patients?]. (2001)

Physical and psychological fitness are required for scuba diving, leading to medical contraindications in certain subjects. Asthma, a condition exhibiting increasing prevalence in the general population is currently considered an absolute contraindication for scuba diving by the French Federation for Submarine Sports and Education (FFESSM). There is however no documented evidence demonstrating a higher risk in asthmatic divers. Our English-speaking colleagues have suggested that certain asthmatic subjects could participate in scuba diving sports under certain conditions without any higher risk compared with non-asthmatic divers. We recall here the impact of diving on respiratory function and potential consequences in asthmatic subjects, proposing that the formal contraindication against scuba diving should be maintained for asthmatic patients who experience frequent symptoms (step 2 or more of the International Consensus Report on Diagnosis and Treatment of Asthma) and/or have a baseline obstructive syndrome. It would appear reasonable to discuss the contraindication concerning patients with rare acute episodes and who have a perfectly normal respiratory function. The question of bronchodilator inhalation prior to diving may be a question to debate. However, such a proposal cannot be considered to be valid unless well-conducted studies of the clinical manifestations are available (frequency and severity of the acute episodes, triggering factors) for the diver candidate. Because of the highly restrictive nature of the contraindication notification and the absence of arguments backing up the decision, the question should be put to competent authorities (sports federations, learned societies) in order to ascertain the pathophysiological mechanisms involved and collect reliable epidemiological data before proposing a consensus discussion. This process may lead to the delivery of scuba diving authorizations for selected asthmatic subjects without a higher risk than non-asthmatic subjects.
