Application du calcul numérique à la dépressurisation des réservoirs cryogéniques en microgravité (2004)

Afin de contrôler la température des ergols cryogéniques dans les réservoirs des lanceurs spatiaux, il est nécessaire de maîtriser des phénomènes thermodynamiques complexes. Pour les lanceurs du futur, l'apparition de phases à microgravité augmente cette complexité et exige des approches numériques plus complètes. Une phase caractéristique qui interviendra en microgravité dans les futurs lanceurs spatiaux est analysée ici : la dépressurisation des réservoirs cryogéniques. De par les difficultés pour réaliser des essais à grande échelle incluant une phase de microgravité avec un liquide cryogénique, on valide nos méthodes numériques par des essais au sol. Ces essais ont été réalisés sur le site de la Division des Techniques Avancées d'Air Liquide dans le cadre du programme franco-allemand COMPERE.
Non-Isolated High Voltage Gain Boost DC-DC Converter with Capability of Canceling Input Current Ripple (2022)

This paper proposes a non-isolated high voltage gain boost dc-dc converter with the feature of canceling input current ripple. At the input port of the proposed converter, there are two coupled inductors are used in an interleaved configuration and the input current passes through the primary winding of coupled inductors. Interleaving helps to solve the problem of high current stress of switches in high voltage gain converters. The proposed converter has two switches in its structure. In the proposed converter, the voltage stress of the switches is less than the peak output voltage. In this paper, the proposed topology is analyzed in all operating modes. The value of current and voltage stresses of switches, input current ripple, and voltage gain are calculated. Finally, the accuracy performance of the proposed converter is reconfirmed through simulation and experimental results.
Recombinant SP-D carbohydrate recognition domain is a chemoattractant for human neutrophils (1999)

Human pulmonary surfactant protein D (SP-D) is a collagenous C-type lectin with high binding specificity to alpha-D-glucosyl residues. It is composed of four regions: a short NH2-terminal noncollagen sequence, a collagenous domain, a short linking domain ("neck" region), and a COOH-terminal carbohydrate recognition domain (CRD). Previous studies demonstrated that SP-D is chemotactic for inflammatory cells. To test which domain of SP-D might play a role in this function, a mutant that contains only neck and CRD regions was expressed in Escherichia coli and purified by affinity chromatography on maltosyl-agarose. A 17-kDa recombinant SP-D CRD was identified by two antibodies (antisynthetic SP-D COOH-terminal and neck region peptides) but not by synthetic SP-D NH2-terminal peptide antibody. The recombinant SP-D CRD was confirmed by amino acid sequencing. Gel-filtration analysis found that 84% of CRD was trimeric and the rest was monomeric. Analysis of the chemotactic properties of the trimeric CRD demonstrated that the CRD was chemotactic for neutrophils (polymorphonuclear leukocytes), with peak activity at 10(-10) M equal to the positive control [formyl-Met-Leu-Phe (fMLP) at 10(-8) M]. The chemotactic activity was abolished by 20 mM maltose, which did not suppress the chemotactic response to fMLP. The peak chemotactic activity of the CRD is comparable to the activity of native SP-D, although a higher concentration is required for peak activity (10(-10) vs. 10(-11) M). The chemotactic response to CRD was largely prevented by preincubation of polymorphonuclear leukocytes with SP-D, and the response to SP-D was prevented by preincubation with CRD. These preincubations did not affect chemotaxis to fMLP. These results suggest that trimeric CRD accounts for the chemotactic activity of SP-D.
Cold-induced changes in cell wall stability determine the resistance of winter triticale to fungal pathogen Microdochium nivale (2016)

The exposure of winter triticale to cold promotes genotype-dependent resistance to fungal pathogen. We present the evidence that structural and chemical modifications of the cell wall components induced by cold can be correlated with the resistance against fungal infection. Our results showed that cellulose of hardened triticale cv. Hewo (able to develop resistance after cold treatment) has more compact and integrated structure, thicker and longer fibres when compared to cv. Magnat (susceptible to fungal infection despite plant hardening). Such structure of cellulose limits water sorption, favours stronger bonding the water of crystallisation to macromolecules, impedes depolymerisation process during decomposition, and finally results in higher thermal stability of cell wall. Furthermore, the lignin composition is drastically modified in resistant plants. Pattern of the thermal decomposition indicates higher molecular mass and more complex structure of lignin, followed by the higher thermal stability. We conclude that specific structure of lignocellulosic cell wall of the resistant plants forms a barrier for fungal enzymes digesting host tissue as well as can resist better the mechanical pressure of hyphae.
<p>Impact of a probiotic-based hospital sanitation on antimicrobial resistance and HAI-associated antimicrobial consumption and costs: a multicenter study</p> (2019)

The spread of AMR in the hospital environment can be limited by the use of sanitation methods to remodulate the hospital microbiota, leading to lower antimicrobial consumption and costs. This approach might be considered as part of broader infection prevention and control strategies.
Silencing ribulose-1,5-bisphosphate carboxylase/oxygenase expression does not disrupt nitrogen allocation to defense after simulated herbivory inNicotiana attenuata (2013)

Ribulose-1,5-bisphosphate carboxylase/ oxygenase (RuBisCO) is the most abundant protein on the planet and in addition to its central role in photosynthesis it is thought to function as a nitrogen (N)-storage protein and a potential source of N for defense biosynthesis in plants. In a recent study in the wild tobacco Nicotiana attenuata, we showed that the decrease in absolute N invested in soluble proteins and RuBisCO elicited by simulated herbivory was much larger than the N-requirements of nicotine and phenolamide biosynthesis; (15)N flux studies revealed that N for defensive phenolamide synthesis originates from recently assimilated N rather than from RuBisCO turnover. Here we show that a transgenic line of N. attenuata silenced in the expression of RuBisCO (asRUB) invests similar or even larger amounts of N into phenolamide biosynthesis compared with wild type plants, consistent with our previous conclusion that recently assimilated N is channeled into phenolamide synthesis after elicitation. We suggest that the decrease in leaf proteins after simulated herbivory is a tolerance mechanism, rather than a consequence of N-demand for defense biosynthesis.
Mitochondrial fission blocker protects brain endothelial cells but not neurons following oxygen‐glucose deprivation (OGD) (2012)

The aim of our study was to investigate the effect of mitochondrial fission blocker Mdivi‐1 on cell survival following OGD in neurons and cerebral vascular endothelial cells. Primary rat cortical neurons were isolated from E18 Sprague Dawley fetuses, while primary rat brain endothelial cells (RBEC) were isolated from 2 week old pups. We also used a human brain endothelial cell (HBEC) line in this study. In the confluent cultures, cell viability was measured following 1, 2, and 3 hour of OGD in HBEC, RBEC, and neuronal cells, respectively, which was followed by 24 hour reoxygenation in each case. Each group had a normoxic control with the same treatment as the OGD plates. Cells were exposed to Mdivi‐1 (2.5 μM‐ 250 μM), an inhibitor of the mitochondrial fission protein, dynamin‐related peptide 1 (Drp1), during the OGD. Mdivi‐1 treatment improved cell viability following OGD by 15–45% in HBEC, and 15% in RBEC compared to untreated cells exposed to OGD. However, Mdivi‐1 failed to change the cell viability in the neurons exposed to OGD. In conclusion, the mitochondrial fission blocker Mdivi‐1, is protective against OGD in endothelial cells from both rat and human, but not in rat neurons.
Activation of cytosolic phosphoinositide phospholipase C by G-protein beta gamma subunits (1992)

Bovine liver cytosol contains a phosphoinositide phospholipase C (PLCcyt) that is activated by guanosine 5'-O-(3-thio)triphosphate (GTP gamma S)-activated G-proteins from liver plasma membranes. Heparin-Sepharose chromatography indicated that PLCcyt was immunologically distinct from PLC-beta 1, PLC-gamma 1, or PLC-delta 1 from brain. Initial purification of the GTP gamma S-activated G-proteins that stimulated PLCcyt indicated that the beta gamma complex was responsible. G-proteins were subsequently extracted from liver membranes as heterotrimers and purified in the presence of AlCl3, MgCl2, and NaF to allow reversible activation. Immunoblot analysis with an antiserum selective for the beta subunit showed that the stimulatory activity corresponded with the presence of this protein at every chromatographic step. When liver beta gamma complex was purified and separated from all detectable alpha subunits, as shown by immunoblotting and silver staining, it strongly stimulated PLCcyt after removal of the activating ligand [AlF4]- by gel filtration. beta gamma prepared from brain was approximately equipotent with that from liver. beta gamma was half-maximally effective at 33 nM and produced a maximal 50-fold activation of the PLC. Under identical conditions, beta gamma had no effect on brain PLC-gamma 1 or PLC-delta 1 and produced a 2-fold stimulation of PLC-beta 1 activity. Addition of purified GDP-bound alpha o, which had no effect by itself, completely reversed the beta gamma activation of PLCcyt, confirming that beta gamma was the active species. These data provide evidence for a novel mechanism by which beta gamma subunits of pertussis toxin-sensitive or -insensitive G-proteins activate phospholipase C.

REACT-1 round 7 updated report: regional heterogeneity in changes in prevalence of SARS-CoV-2 infection during the second national COVID-19 lockdown in England (2020)

Background England exited a four-week second national lockdown on 2nd December 2020 initiated in response to the COVID-19 pandemic. Prior results showed that prevalence dropped during the first half of lockdown, with greater reductions in higher-prevalence northern regions. Methods REACT-1 is a series of community surveys of SARS-CoV-2 RT-PCR swab-positivity in England, designed to monitor the spread of the epidemic and thus increase situational awareness. Round 7 of REACT-1 commenced swab-collection on 13th November 2020. A prior interim report included data from 13th to 24th November 2020 for 105,122 participants. Here, we report data for the entire round with swab results obtained up to 3rd December 2020. Results Between 13th November and 3rd December (round 7) there were 1,299 positive swabs out of 168,181 giving a weighted prevalence of 0.94% (95% CI 0.87%, 1.01%) or 94 per 10,000 people infected in the community in England. This compares with a prevalence of 1.30% (1.21%, 1.39%) from 16th October to 2nd November 2020 (round 6), a decline of 28%. Prevalence during the latter half of round 7 was 0.91% (95% CI, 0.81%, 1.03%) compared with 0.96% (0.87%, 1.05%) in the first half. The national R number in round 7 was estimated at 0.96 (0.88, 1.03) with a decline in prevalence observed during the first half of this period no longer apparent during the second half at the end of lockdown. During round 7 there was a marked fall in prevalence in West Midlands, a levelling off in some regions and a rise in London. R numbers at regional level ranged from 0.60 (0.41, 0.80) in West Midlands up to 1.27 (1.04, 1.54) in London, where prevalence was highest in the east and south-east of the city. Nationally, between 13th November and 3rd December, the highest prevalence was in school-aged children especially at ages 13-17 years at 2.04% (1.69%, 2.46%), or approximately 1 in 50. Conclusion Between the previous round and round 7 (during lockdown), there was a fall in prevalence of SARS-CoV-2 swab-positivity nationally, but it did not fall uniformly over time or by geography. Continued vigilance is required to reduce rates of infection until effective immunity at the population level can be achieved through the vaccination programme.
Selection against Mastitis and Cell Count in Dairy Cattle Breeding Programs (1992)

Abstract Different selection strategies were studied to improve milk traits and to reduce the frequency of clinical mastitis and somatic cell count. The results indicate that it is better to use both clinical mastitis and somatic cell count in the selection index to improve the resistance of animals to mastitis and to improve the quality of milk. Selection for protein yield simultaneously with selection against mastitis or somatic cell count would result in increased milk, fat and protein yields, increased protein content, decreased fat content and decreased frequency of clinical mastitis and somatic cell count. Maximizing the total net economic profit based on the current pricing system in Finland would not decrease somatic cell count or frequency of clinical mastitis.
What can we learn from accident videos? (2013)

A recent rise of windshield mounted cameras in cars has given access to large amount of videos from real world traffic accidents. This paper aims to analyze what can be learned from that video data using current state-of-the-art computer vision techniques. We also discuss what is currently missing to fully understand these videos. A substantial number of accident sequences has been acquired and manually evaluated for this analysis. The ability to fully automatically analyze large numbers of traffic accidents from videos will allow to identify potentially dangerous traffic scenarios, improve driving safety and driver warning systems.

Path-Loss-Based Fingerprint Localization Approach for Location-Based Services in Indoor Environments (2017)

Wireless local area network fingerprint-based indoor localization schemes have been widely studied because of the increasing requirements of location-based services (LBSs). The features of fingerprint based localization are known to have higher precision in indoor environments than traditional methods, such as triangulation. However, the precision depends on the amount of pre-created received signal strength (RSS) fingerprints, which is associated with the number of reference points (RPs) of the RSS measurements and the available signal sources in the environment. In this paper, we consider the resource limitations of todays' wireless environment and propose an improved fingerprint-based localization approach that adapts a path loss model for fingerprint creation and localization. Based on the proposed approach, we present two related localization schemes. The first is a path-loss-based fingerprint localization (PFL) scheme and the second is a dual-scanned fingerprint localization (DFL) scheme. The PFL attempts to improve positioning precision, and the DFL attempts to guarantee positioning reliability. Several simulations are performed, and they show that the proposed schemes improve the positioning precision and reliability in resource-limited environments, which would improve the practicability of fingerprint-based localizations in indoor LBSs.

Numerical Computation of Parametric Induced Roll Motions in Random Seas (2009)

Abstract For a vessel in open seas, the sudden appearance of roll motions due to waves from the front or rear leads to dangerous situations up to capsizing. The equations of motion used to analyze the roll motion include the righting lever curve. This curve is set up by means of hydrostatic calculations and approximated by polynomials for further analysis. The irregular waves are modeled in terms of a continuous‐time ARMA process. The resulting model of stochastic differential equations is investigated numerically by Local Statistical Linearization. The necessary stochastic moments and their derivatives are computed using Itô's differential rule and Gaussian closure. (© 2009 Wiley‐VCH Verlag GmbH &amp; Co. KGaA, Weinheim)
Substrate exchange in human limb muscle during exercise at reduced blood flow (1988)

The substrate exchange of the calf muscles during leg exercise was compared in patients with chronically reduced blood flow and in matched controls. The arteriovenous differences of glucose, lactate, pyruvate, free fatty acids, glycerol, acetoacetate, beta-OH-butyrate, oxygen, and carbon dioxide were analyzed at rest, at the end of two exercise periods at various work loads, and after 10 min of recovery. Calf blood flow was measured with an electrocardiogram-triggered, computerized, strain gauge, venous occlusion plethysmograph. The results indicate that there was increased extraction of oxygen and ketone bodies in patients with reduced blood flow during exercise, whereas the glucose extraction tended to be lower than in controls. The leg respiratory quotient was lower in the patients even at the point of claudicating pain, suggesting oxidation of endogenous fat. The simultaneously elevated lactate release can be explained by local hypoxia in some muscle fiber populations. The findings are discussed in relation to the enzymatic adaptations known to occur in the calf muscle tissue of these patients.
IMPACT OF SLUDGE CONDITIONING ON MECHANICAL DEWATERING AND CONVECTIVE DRYING (2011)

Abstract: Management of sludge produced within wastewater treatment plants has become a key issue. After thickening, the removal of remaining water using mechanical dewatering and/or thermal drying is essential before any type of valorization. Polymers are usually employed in the conditioning step in order to promote particle aggregation, making the dewatering easier. In this work the impact of the polymer dosage and nature on dewatering and convective drying of sludge is studied. Results clearly show the impact of conditioning on dewatering performances, however no effect on drying has been observed within the range of tested experimental conditions.
Optimum Design of Ladder Type SAW Filter Using a Simulated Annealing (2007)

Surface Acoustic Wave (SAW) filters are a key device for mobile communication systems, and the high performance and low-loss of SAW filters has been increasing rapidly. The general design procedures for practical SAW filter are a trial-and-error approach by expert designers. The researches on the design of SAW filters using some different optimization algorithms (i.e. variable neighborhood search) have been the local search method so far. In these researches, the SAW filters are IDT type. Recently, the front-end with ladder type filter has proposed. This filter is low-loss type. The research of the ladder type SAW filter design using the optimization algorithm has not been performed. So, this paper proposed the design method of a ladder type SAW filter using simulated annealing.

It this talk I will review the objectives of the IHY, and the progress made in the deployment of several instrument arrays and investigations which study space weather phenomena.
Long-Range Energy Propagation in Nanometer Arrays of Light Harvesting Antenna Complexes (2010)

Here we report the first observation of long-range transport of excitation energy within a biomimetic molecular nanoarray constructed from LH2 antenna complexes from Rhodobacter sphaeroides. Fluorescence microscopy of the emission of light after local excitation with a diffraction-limited light beam reveals long-range transport of excitation energy over micrometer distances, which is much larger than required in the parent bacterial system. The transport was established from the influence of active energy-guiding layers on the observed fluorescence emission. We speculate that such an extent of energy migration occurs as a result of efficient coupling between many hundreds of LH2 molecules. These results demonstrate the potential for long-range energy propagation in hybrid systems composed of natural light harvesting antenna molecules from photosynthetic organisms.
The National Ignition Facility: beam area increase (2013)

The National Ignition Facility (NIF) is the world’s most energetic laser, having demonstrated in excess of 1.9MJ @351nm with Inertial Confinement Fusion pulse-shapes in July, 2012. First commissioned with 192 operational beamlines in March, 2009, NIF has since transitioned to routine operation for stockpile stewardship, inertial confinement fusion research, and basic high energy density science.
