Performance analysis of 802.11 DCF parameters which support QoS in emergency scenarios (2011)

In case of an emergency, first responders need to establish a communication network at the area of incidence. To support upcoming multimedia services for emergency personnel, a communication technology which provides high data rates is required. At presence the most common wireless communication technology is IEEE 802.11, which provides sufficient data rates for emergency communication. Due to the popularity of IEEE 802.11 networks, existing networks at the incident scene cause harsh conditions for wireless communications. For first respon-ders, a reliable communication infrastructure is crucial. Hence the applied communication technology must provide Quality of Service (QoS). Existing QoS mechanisms, like IEEE 802.11e are designed for multimedia applications. In this paper, we present a new set of parameters for the DCF to support QoS in emergency scenarios. We propose six novel priority classes for heterogeneous types of emergency communication. All types of emergency communication are prioritized over legacy IEEE 802.11 communication. The performance of the new parameter set is analyzed through an analytical model based on Markov chains and is validated through simulations. The results lead to the conclusion that our proposed parameter set provides a reliable communication network for emergency scenarios, even with existing interference networks.
Detection of Plasmodium falciparum and Plasmodium vivax subclinical infection in non-endemic region: implications for blood transfusion and malaria epidemiology (2014)

The presence of Plasmodium in healthy blood donors from a region known as non-endemic, which is important in the context of transfusion biosafety, was described. Infected recipients may become asymptomatic carriers and a reservoir for parasites, maintaining their transmission. Furthermore, P. falciparum PR was positively associated with the forest environment, and P. vivax was associated with forest fragmentation.

Octopamine Receptors, Adenosine 3′,5′-Monophosphate, and Neural Control of Firefly Flashing (1979)

An adenylate cyclase activated as much as 25-fold by low concentrations of octopamine has been identified in the firefly lantern. The relative potency of octopamine and various other amines in stimulating this enzyme, and effects of antagonists in blocking octopamine activation, correlate well with the known effects of these agents in affecting light production. In addition to suggesting a role for adenosine 3',5'-monophosphate (or pyrophosphate) in the neural control of firefly flashing, identification of this potent enzyme should facilitate the characterization of phenylethylamine receptors in excitable tissue.
Scanning Activity Gravimetric Analysis (2006)

We introduce a new techniquescanning activity gravimetric analysis (SAGA)for investigating phase transitions in semicrystalline polymers. Isothermal growth and dissolution of polymer crystallites within picogram to milligram samples are manifested by mass changes in response to changes in the activity of sorbed solvent vapor. Single charged particles are levitated and weighed in an electrostatic field, providing access to highly supersaturated states. Phase transitions are inferred from simultaneous sorption and light scattering measurements. Analogous to differential scanning calorimetry, scanning solvent activity up and down exposes broad transitions between the semicrystalline solid state and the dissolved state, which are influenced by sample history. We demonstrate repeated dissolution and crystallization of an 11 ng sample of poly(ethylene oxide) by controlling the activity of sorbed water vapor and observe self-nucleation of crystallites from partially and fully solvated states.
Heralded single photons from a single quantum dot (2001)

Summary form only given. A deterministic single photon source emitting triggered (heralded) photons on demand, also termed single photon turnstile device, is one of the key elements in the emerging field of quantum information science. We present a single photon source based on pulsed laser excitation of a single self-assembled InAs quantum dot (QD) embedded in a high quality (Q) factor microcavity structure. Regulation of the photon emission process of the QD exciton ground state (1X) transition is accomplished by a combination of two effects: Coulomb interactions creating an anharmonic multiexciton spectrum and a slow relaxation of highly excited QDs leading to vanishing re-excitation probability following the photon emission event at the 1X transition.
Toward a Theory of Probabilistic Automata with Environments, (1978)

Abstract : The viewpoint is taken that every probabilistic automation is situated within a sequence of environments which affects the initial state distribution and the transition function. There exists a probabilistic automaton within a deterministic environment sequence (ADE) which defines an event which is not a PCE, yet in certain nontrivial cases the behavior of an ADE can be simulated by a probabilistic automaton. For probabilistic automata within random environment sequences there is a mean equivalent canonical representation which eliminates the randomness due to probabilistic transition. (Author)
Chemical and Mineralogical Characterizations of Pb in a Contaminated Soil:  Reactions with Synthetic Apatite (1996)

Previous studies have shown that the interactions of apatite with dissolved Pb are caused by the dissolution of apatite grains concomitant with the precipitation of lead orthophosphates (pyromorphites). The present study extends this work by examining the interactions of selected Pb minerals and a Pb-contaminated soil with apatite. Specimen-grade PbO and PbCO3 were reacted separately with hydroxylapatite (HA) in controlled pH reactors. Hydroxypyromorphite (HP) formed at the expense of HA, PbO, and PbCO3 after a reaction period of 2 days, causing significant decreases in aqueous Pb concentrations. The extent of reaction was pH dependent, with more HP formation at pH 5 than at pH 6 or pH 7. Equilibrium modeling with MINEQL+ indicated the stoichiometric conversion of the native Pb solids to HP at all pH values examined in laboratory experiments. In companion experiments, particle size and density separation techniques were used to obtain Pb-enriched fractions from a contaminated soil. These were identified as PbO and PbCO3 with X-ray diffraction (XRD) and scanning electron microscopy (SEM). The Pb-enriched fractions were reacted with HA, and the formation of HP (at the expense of “native” Pb solids) was observed by XRD and SEM. Clearly, apatite amendments to Pb-contaminated soil materials can induce the formation of pyromorphites.

A Genetically Tagged Psb27 Protein Allows Purification of Two Consecutive Photosystem II (PSII) Assembly Intermediates in Synechocystis 6803, a Cyanobacterium (2011)

Photosystem II (PSII) is a large membrane bound molecular machine that catalyzes light-driven oxygen evolution from water. PSII constantly undergoes assembly and disassembly because of the unavoidable damage that results from its normal photochemistry. Thus, under physiological conditions, in addition to the active PSII complexes, there are always PSII subpopulations incompetent of oxygen evolution, but are in the process of undergoing elaborate biogenesis and repair. These transient complexes are difficult to characterize because of their low abundance, structural heterogeneity, and thermodynamic instability. In this study, we show that a genetically tagged Psb27 protein allows for the biochemical purification of two monomeric PSII assembly intermediates, one with an unprocessed form of D1 (His27ΔctpAPSII) and a second one with a mature form of D1 (His27PSII). Both forms were capable of light-induced charge separation, but unable to photooxidize water, largely because of the absence of a functional tetramanganese cluster. Unexpectedly, there was a significant amount of the extrinsic lumenal PsbO protein in the His27PSII, but not in the His27ΔctpAPSII complex. In contrast, two other lumenal proteins, PsbU and PsbV, were absent in both of these PSII intermediate complexes. Additionally, the only cytoplasmic extrinsic protein, Psb28 was detected in His27PSII complex. Based on these data, we have presented a refined model of PSII biogenesis, illustrating an important role of Psb27 as a gate-keeper during the complex assembly process of the oxygen-evolving centers in PSII.
Patterns of relapse in poor-prognosis germ cell tumors in the GETUG 13 trial: Implications for assessment of brain progression. (2014)

365 Background: GETUG 13 investigated personalized chemotherapy based on tumor marker decline in patients with poor-prognosis GCT and demonstrated that a dose-dense regimen improves progression-free survival in patients with an unfavorable decline (Fizazi K, ASCO 2013). We investigated the pattern of relapse for patients included in GETUG 13. Methods: We conducted an analysis of relapse events in patients from GETUG 13 and an unfavorable decline of tumor markers (n=203). Baseline procedures before inclusion in the trial comprised a thoraco-abdomino-pelvic CT scan and an MRI of the brain: 22 patients (10%) had evidence of brain metastases at presentation. Results: With a median follow-up of 4.1 years (0.3 ; 8.8 years) when the analysis was performed, a progression event was observed in 94/203 patients (46%). First event consisted in a marker progression only in 41 patients (43%), a radiographic progression only in 29 patients (31%), a mix progression on both markers and imaging in 11 patients (12%), and death in 13 patients (14%). In patients with radiographic progression only, brain was the predominant site (n=16/29, 55%). Among all patients who experienced a radiographic progression (as first and subsequent progression event, n=58), brain only was the site of progression in 26 patients (45%): 12/30 (40%) in patients treated with BEP and 14/28 (50%) in those treated with dose-dense chemotherapy. Conclusions: Brain metastases develop often, early, and frequently as the only site of relapse in the course of poor-prognosis GCT. This raises the question of early detection and treatment of brain metastases in these patients, for example by integrating a systematic brain MRI after 2-3 months of chemotherapy.
Robust lossless watermarking based on circular interpretation of bijective transformations for the protection of medical databases (2012)

In this paper, we adapt the image lossless watermarking modulation proposed by De Vleeschouwer et al., based on the circular interpretation of bijective modulations, to the protection of medical relational databases. Our scheme modulates the numerical attributes of the database. It is suited for either copyright protection, integrity control or traitor tracing, being robust to most common database attacks, such as the addition and removal of tuples and the modification of attributes' values. Conducted experiments on a medical database of inpatient hospital stay records illustrate the overall performance of our method and its suitability to the requirements of the medical domain.
Post-Translational Regulation of miRNA Pathway Components, AGO1 and HYL1, in Plants (2016)

Post-translational modifications (PTMs) of proteins are essential to increase the functional diversity of the proteome. By adding chemical groups to proteins, or degrading entire proteins by phosphorylation, glycosylation, ubiquitination, neddylation, acetylation, lipidation, and proteolysis, the complexity of the proteome increases, and this then influences most biological processes. Although small RNAs are crucial regulatory elements for gene expression in most eukaryotes, PTMs of small RNA microprocessor and RNA silencing components have not been extensively investigated in plants. To date, several studies have shown that the proteolytic regulation of AGOs is important for host-pathogen interactions. DRB4 is regulated by the ubiquitin-proteasome system, and the degradation of HYL1 is modulated by a de-etiolation repressor, COP1, and an unknown cytoplasmic protease. Here, we discuss current findings on the PTMs of microprocessor and RNA silencing components in plants.
The mitochondrial tRNALeu(UUR) mutation in MELAS: a model for pathogenesis (1992)

The A----G transition at nucleotide 3243 of the mitochondrial tRNA(Leu)(UUR)) gene has been associated with MELAS, a maternally-inherited mitochondrial disorder. We recently transferred mitochondria harboring this mtDNA mutation into a human cell line devoid of endogenous mtDNA (rho degrees cells), and showed: (1) decreased rate of synthesis and of steady-state levels of mitochondrial translational products, (2) reduced respiratory chain function and (3) increased amounts of a novel unprocessed RNA species (termed by us RNA 19) derived from transcription of the 16S rRNA + tRNA(Leu)(UUR) + ND 1 genes. Because RNA 19 contains rRNA sequences, we propose that this molecule is incorporated into mitochondrial ribosomes, and interferes disproportionately with mitochondrial translation, thereby causing the phenotypic changes associated with MELAS.

Photoelectron emission studies in CsBr at 257nm (2006)

Cs Br ∕ Cr photocathodes were found [J. R. Maldonado et al., J. Vac. Sci. Technol. B 22, 3025 (2004); J. R. Maldonado et al., Proc. SPIE 5520, 46 (2003)] to meet the requirements of a multielectron beam lithography system operating with a light energy of 4.8eV (257nm). The fact that photoemission was observed with a light energy below the reported 7.3eV band gap for CsBr was not understood. This article presents experimental results on the presence of intra-band-gap absorption sites (IBASs) in CsBr thin film photoelectron emitters, and presents a model based on IBAS to explain the observed photoelectron emission behavior at energies below band gap. A fluorescence band centered at 330nm with a full width at half maximum of about 0.34eV was observed in CsBr∕Cr samples under 257nm laser illumination, which can be attributed to IBAS and agrees well with previously obtained synchrotron photoelectron spectra [J. R. Maldonado et al., J. Vac. Sci. Technol. B 22, 3025 (2004)] from the valence band of CsBr films.

Material requirements for high efficiency CuInSe/sub 2//CdS solar cells (1984)

CuInSe/sub 2//CdS solar cells with efficiencies greater than 8% have been made by the elemental evaporation of CuInSe/sub 2/ onto Pt and Mo contacts. Both Pt and Mo can give I-V characteristics which show a 'second diode blocking contact' in the completed cell. The 'second diode' behavior does not appear to affect the final device efficiency. In-doped high conductivity CdS was usually evaporated onto the CuInSe/sub 2/ to make the final device. High conductivity CdS was used to ensure that most of the depletion layer would be in the CuInSe/sub 2/ thereby aiding in the collection of minority carriers and giving a diode quality factor close to unity. Other devices have been made over a range of CdS conductivities in order to increase understanding of junction behavior.
Electrophoretic and immunochemical analysis of surface antigens of the fish pathogens <i>Vibrio salmonicida</i> and <i>Vibrio anguillarum</i> (1990)

Abstract. Outer membranes and lipopolysaccharides of the marine fish pathogens Vibrio salmonicida and Vibrio anguillarum were isolated. SDS‐PAGE profiles of purified LPS preparations from V. salmonicida revealed a broad low molecular weight band, whereas V. anguillarum LPS profiles demonstrated both a low‐molecular band and several weaker high‐molecular weight bands. Hydrolysis of V, salmonicida and V. anguillarum LPS separating the polysaccharide chain from the lipid A part and subsequent gel‐chromatography suggests a polysaccharide molecular weight of ca. 1000 (‘rough type’ LPS) and ca. 6000 ('smooth type’ LPS), respectively. Western blot of V. salmonicida outer membrane preparations and purified lipopolysaccharides and subsequent immunostaining with mouse monoclonal antibodies was performed. Eleven out of 15 monoclonal antibodies made against V. salmonicida cells reacted with one broad antigen‐band in the low molecular weight region of both outer membrane and LPS profiles, corresponding to the LPS region. The previously reported outer surface antigen, VS‐P1 from V. salmonicida , was observed to carry LPS epitopes as revealed by binding of monoclonal antibodies to VS‐P1 as well as purified LPS preparations. These results strongly suggest that the VS‐P1 antigen is a complex of both protein and LPS molecules.
CC-Chemokine Receptor 6 Is Expressed on Diverse Memory Subsets of T Cells and Determines Responsiveness to Macrophage Inflammatory Protein 3α (1999)

Abstract CC-chemokine receptor (CCR) 6 is the only known receptor for macrophage inflammatory protein (MIP)-3α, a CC chemokine chemotactic for lymphocytes and dendritic cells. Using anti-serum that we raised against the N-terminal residues of CCR6, we have characterized the surface expression of CCR6 on peripheral blood leukocytes and we have correlated CCR6 expression with responses to MIP-3α. We found that CCR6 was expressed only on memory T cells, including most α4β7 memory cells and cutaneous lymphocyte-associated Ag-expressing cells, and on B cells. Accordingly, chemotaxis of T cells to MIP-3α was limited to memory cells. Moreover, calcium signals on T cells in response to MIP-3α were confined to CCR6-expressing cells, consistent with CCR6 being the only MIP-3α receptor on peripheral blood T cells. Unlike many CC chemokines, MIP-3α produced a calcium signal on freshly isolated T cells, and CCR6 expression was not increased by up to 5 days of treatment with IL-2 or by cross-linking CD3. Despite their surface expression of CCR6, freshly isolated B cells did not respond to MIP-3α. In addition to staining peripheral blood leukocytes, our anti-serum detected CCR6 on CD34+ bone marrow cell-derived dendritic cells. Our data are the first to analyze surface expression of CCR6, demonstrating receptor expression on differentiated, resting memory T cells, indicating differences in receptor signaling on T cells and B cells and suggesting that CCR6 and MIP-3α may play a role in the physiology of resting memory T cells and in the interactions of memory T cells, B cells, and dendritic cells.
Navigation: am I really lost or virtually there? (2001)

Data is presented from virtual environment (VE) navigation studies that used building- and chessboard-type layouts. Participants learned by repeated navigation, spending several hours in each environment. While some participants quickly learned to navigate efficiently, others remained almost totally disoriented. In the virtual buildings this disorientation was illustrated by mean direction estimate errors of approximately 90°, and in the chessboard VEs disorientation was highlighted by the large number of rooms that some participants visited. Part of the cause of disorientation, and generally slow spatial learning, lies in the difficulty participants had learning the paths they had followed through the VEs.
Serum hyaluronate correlates with histological progression in alcoholic liver disease (2003)

Les réserves biologiques en France : de la dynamique dirigée à la dynamique spontanée (2005)

L’instruction sur les réserves biologiques intégrales (décembre 1998) fait référence à la résolution H2 de la conférence d’Helsinki, en juin 1993, qui a retenu une formulation complexe et ambiguë : « Les États signataires et la Communauté européenne établiront, au plan régional ou national, un réseau cohérent de forêts climaciques, primaires ou présentant un intérêt particulier, visant à maintenir ou à reconstituer des écosystèmes représentatifs ou menacés. » L’emploi du terme « climax » aura...
