Conception et construction d'une expérience d'atomes froids : vers un condensat de sodium sur puce

Dans cette these, nous decrivons les premieres etapes de la construction d’une experience de condensation d’atomes de sodium. A terme, le dispositif integrera une puce a atomes qui permettra d’etudier la dynamique hors equilibre de gaz quantiques de dimensionnalite reduite, ainsi que leur dynamique de relaxation. Le montage experimental est constitue d’un systeme laser stabilise en frequence sur une raie de l’iode, ainsi que d’une enceinte a ultra-vide. Cette derniere comporte un four produisant un jet atomique effusif qui est decelere dans un ralentisseur Zeeman a aimants permanents.Nous obtenons alors un flux de 2 x 108 atomes/s, ce qui nous permet de charger pres de 109 atomes dans un piege magneto-optique. Durant la caracterisation du ralentisseur Zeeman, nous avons mis en evidence un mecanisme de redistribution des populations atomiques vers l’etat F = 1 en amont du ralentisseur, induit par l’interaction avec le faisceau Zeeman. Apres avoir confirme ces observations par une resolution numerique des equations de Bloch optiques, nous avons mis en place un faisceau laser avec deux composantes de frequence permettant de preparer initialement les atomes dans le sous-niveau F = 2;mF = - 2 pour les preserver de cet effet. Enfin, nous avons concu un dispositif de transport magnetique permettant d’acheminer les atomes depuis l’enceinte du piege magneto-optique vers l’enceinte du condensat. Des simulations de dynamique moleculaire nous ont permis de determiner une sequence temporelle pour le deplacement du nuage performante, autorisant un transport de 65 cm en 1 s.Mots cles : sodium, condensation de Bose-Einstein, puce a atomes, ralentisseur Zeeman, aimants permanents, transport magnetique, dynamique moleculaire.

Three addend addition: Who goes out of order and why?

Single-digit, three addend sums of the type a + b + c offer a rich opportunity to directly observe the range of strategies that different participants may use because they afford the possibility of measuring a partial sum (i.e., a + b or a + c or b + c). For example, while computing the sum 9 + 7 + 1, do participants go in order by first adding 9 + 7 and then adding 1, or do they incur the cost of going out of order by adding 9 + 1 in order to obtain the partial sum of 10, which makes the subsequent addition of 7 less effortful? Informed by findings in simple and complex arithmetic, we investigated the problem types and participant characteristics that can predict out of order switching behavior in such three-addend sums. To test our hypotheses, we tasked participants, first in an online study, and then in an in-person study to complete 120 single-digit, three addend problems. We found that participants switched the order of addition to prioritize efficiency gains in contexts in which the partial sum addends were small or equal to each other, or when doing so led to a partial sum of 10, or led to a partial sum that is equal to the third remaining integer. Response latency data confirmed that participants were deriving efficiencies in the manner we expected. Related to individual differences, our findings showed that participants with higher levels of math education were most likely to seek efficiency benefits whenever they were on offer.
Low Frequency of Poultry-to-Human H 5 N 1 Virus Transmission , Southern Cambodia , 2005

1542 Emerging Infectious Diseases • www.cdc. gov/eid • Vol. 12, No. 10, October 2006 To understand transmission of avian influenza A (H5N1) virus, we conducted a retrospective survey of poultry deaths and a seroepidemiologic investigation in a Cambodian village where a 28-year-old man was infected with H5N1 virus in March 2005. Poultry surveys were conducted within a 1-km radius of the patient’s household. Forty-two household flocks were considered likely to have been infected from January through March 2005 because >60% of the flock died, case-fatality ratio was 100%, and both young and mature birds died within 1 to 2 days. Two sick chickens from a property adjacent to the patient’s house tested positive for H5N1 on reverse transcription– PCR. Villagers were asked about poultry exposures in the past year and tested for H5N1 antibodies. Despite frequent, direct contact with poultry suspected of having H5N1 virus infection, none of 351 participants from 93 households had neutralizing antibodies to H5N1. H5N1 virus transmission from poultry to humans remains low in this setting.
Assessment of Need of Antenatal Education by Assessing the Existing Knowledge of Pregnant Women

OBJECTIVE: To assess the antenatal knowledge and preferred information seeking behavior of pregnant women attending antenatal care clinics of Allied Hospitals of Rawalpindi Medical University, Rawalpindi.METHODOLOY: This was a multi-centered based cross-sectional design study. This study was conducted in the antenatal care clinics of three allied hospitals of Rawalpindi medical University, Rawalpindi. A total of 400 pregnant women in third trimester of pregnancy, attending antenatal care clinics were included in the study through consecutive sampling. Antenatal knowledge was assessed by a valid (scale-content validity index=1.00) and reliable (Cronbach’s alpha=0.90) questionnaire developed for this purpose. SPSS 22 was used for data analysis. RESULTS: Out of 400 pregnant women, majority 148 (37%) were in the age group of 23-27 years. Mean age was 26.5±4.8 years. Mean antenatal knowledge score was 28±6.2. Two hundred and sixty-eight (67%) women had poor (˂70% score), ninety-six (24%) had adequate (70%-80% score) and thirty-six (9%) had good (˃80% score) level of antenatal knowledge. Three hundred and sixty (90%) women had poor nutritional and gestational weight gain knowledge. Antenatal knowledge scores were significantly associated with education, number of antenatal care visits, locality and monthly household income. One to one education was preferred format by most (53%) of women. Doctors were the preferred source of information by 80% of the participants.CONCLUSION: The findings of the study indicate that most of the pregnant women lack the adequate antenatal knowledge while one to one education given by doctors was the preferred mode of health education by the majority of the participants. KEYWORDS: Pregnant women, Antenatal education, Antenatal knowledge
Value of bronchial wash and brush cytology in addition to histology in the diagnosis of lung cancer

A retrospective study was performed to evaluate the diagnostic yield of lung cancer on biopsy, bronchial washings and brushings taken at fibreoptic bronchoscopy. Records of 526 patients were analysed and eventually 107 patients with endobronchial lesions, who had had biopsy, washing and brushing were included in this study. 89 cases were found to be malignant. Squamous cell carcinoma was the most common malignancy. Brush was found to be better than wash in tumor typing, though overall tumor typing using cytology was poor. Sensitivities of bronchial wash, bronchial brush and biopsy were found to be 70.8%, 64% and 94.4% respectively. Biopsy gave the only positive result in 38.2%, only brush in 1.1% and only wash in 1.1% malignant cases. Diagnostic accuracy of bronchial biopsy, brush and wash was found to be 95.3%, 70% and 73.8% respectively. Addition of bronchial wash and brush increased the positive yield by only 2.2% which was insignificant. It was concluded that the wash and brush cytology do not significantly add to the overall yield of positive results obtained from biopsies in endobronchial lesions.

A Fatty Acid-Inspired Tetherable Initiator for Surface-Initiated Atom Transfer Radical Polymerization

A universal tetherable initiator, derived from the structure of fatty acids, for surface-initiated atom transfer radical polymerization (SI-ATRP) from metal oxide surfaces was prepared. A simple amidation between 2-bromoisobutyryl bromide and ω-aminolauric acid allowed preparation of 12-(2-bromoisobutyramido)dodecanoic acid (BiBADA). After facile purification, BiBADA was used as a tetherable initiator for a broad range of metal oxide nanoparticles. The modified nanoparticles were grafted with methyl methacrylate or n-butyl acrylate via SI-ATRP with a high grafting density. This is the first report of successful SI-ATRP from a selection of different metal oxide nanoparticles. Sub-10 nm Fe3O4 nanoparticles with an intrinsically tethered initiator were also prepared using BiBADA as a surfactant template. Additional experiments demonstrated successful modification of an aluminum foil surface with polymer brushes using BiBADA as a tetherable initiator.
The Health Literacy of Employees in Educational-Rehabilitation Centers Affiliated to The Welfare Organization

Background and Objective: Health literacy provides the capacity and basic understanding of health information and services for individuals to make health decisions. This study aimed to determine the health literacy of employees in educational-rehabilitation centers affiliated to the Welfare Organization of Hamadan province in 2019. Materials and Methods: This cross-sectional study was conducted on 106 participations. Sampling was done by censuses method. Data was collected with the test of functional health literacy in adults (TOFHLA) and demographic questionnaire, and analyzed by, ANOVA, chi-squared tests via SPSS software version 21. Results: The mean age of participants was 34.25± 8.19 years in females and 34.44± 8.60 years in males, and 90.57% were female, and 66.98% of them were married. The health literacy score was 65.90 ± 21.10, and 32.29% of females and40% of males were at an adequate level of health literacy. Level of health literacy was significantly different between participants with diffrent education level (P <0001), type of rehabilitation center (p = 0.001), specialized services of the center (P <0001), and gender. Conclusion: The level of health literacy of more than half of the employees in the rehabilitation-educational centers affiliated with the welfare organization is inadequate and marginal. Due to the vulnerability of welfare clients, it is necessary to pay more attention to health literacy in health promotion programs in this organization.
Extraction of sweet wormwood (Artemisia annua L.) by supercritical carbon dioxide

In this study, supercritical carbon dioxide was applied for the extraction of Artemisia annua L. Moreover, the impact of different parameters of supercritical extraction on total yield was investigated and the obtained yields were compared to the ones obtained by conventional procedures, hydrodistillation and Soxhlet extraction. Supercritical fluid extraction at 40 °C and different pressures (100, 200, and 300 bar) resulted in extraction yields that were in the 2.23-5.18 % range, while the yields at 60 °C and the same pressures were in the range 2.43-3.35 %. The yields obtained by the Soxhlet extraction and hydrodistillation were 10.28 % and 0.10 %, respectively. Although supercritical fluid extraction is inferior to Soxhlet extraction in terms of the recovery of lipophilic components of A. annua, the Soxhlet extraction is not the method of choice for obtaining sweet wormwood extracts due to its numerous disadvantages that include the use of toxic solvents, extended extraction time, health safety of the product, the need for further processing, the impossibility of adjusting the selectivity and thus the composition of the product.
Wildfire Impacts on Soil Physical and Chemical Properties-A Short Review of Recent Studies

Wildfires are key drivers of changes in soils and the ecosystems. The temperatures reached during a wildfire dictate for the most part the post-fire changes in the soil-system. Additionally, the duration and severity of the wildfire, together with different soil characteristics (e.g. soil organic matter or moisture content) play an important part in the direction and nature of the post-fire changes. Wildfires affect the soil by heating and later trough ash incorporation in topsoil. Wildfire severity determines the degree of vegetation and litter combustion and the soil physical and chemical modifications. Post-fire alterations in soil and its hydrological processes promote erosion in the topsoil layer, which is often associated with quantitative and qualitative changes in soil organic matter. The recovery of soil organic matter is the key for the overall recovery of soil quality after a wildfire. The duration and extremity of the changes of soil properties depend on the severity of the wildfire. Wildfire severity is conditioned by various environmental factors, for example vegetation quantity and type, soil temperature and humidity, wind speed and topography. This paper reviews various studies on the impacts of wildfire on soil chemical and physical properties and sums up the current knowledge on the topic that is increasingly becoming a vital component in recognizing and understanding the mechanisms of adaptation of the global ecosystem to climate change. It is paramount to continue the research of wildfire impacts on soil properties in the attempt to more easily quantify soil degradation processes, predict the ecosystem response to wildfire, and assure the appropriate land management techniques.
A pr 2 01 6 Cohomology with causally restricted supports

De Rham cohomology with spacelike compact and timelike compact supports has recently been noticed to be of importance for understanding the structure of classical and quantum Maxwell theory on curved spacetimes. Similarly causally restricted cohomologies of different differential complexes play a similar role in other gauge theories. We introduce a method for computing these causally restricted cohomologies in terms of cohomologies with either compact or unrestricted supports. The calculation exploits the fact that the de Rham-d’Alembert wave operator can be extended to a chain map that is homotopic to zero and that its causal Green function fits into a convenient exact sequence. As a first application, we use the method on the de Rham complex, then also on the Calabi (or Killing-Riemann-Bianchi) complex, which appears in linearized gravity on constant curvature backgrounds. We also discuss applications to other complexes, as well as generalized causal structures and functoriality.

Learning Correlated Communication Topology in Multi-Agent Reinforcement learning

Communication improves the efficiency and convergence of multi-agent learning. Existing study of agent communication has been limited on predefined fixed connections. While an attention mechanism exists and is useful for scheduling the communication between agents, it, however, largely ignores the dynamical nature of communication and thus the correlation between agents’ connections. In this work, we adopt a normalizing flow to encode correlation between agents interactions. The dynamical communication topology is directly learned by maximizing the agent rewards. In our end-to-end formulation, the communication structure is learned by considering it as a hidden dynamical variable. We realize centralized training of critics and graph reasoning policy, and decentralized execution from local observation and message that are received through the learned dynamical communication topology. Experiments on cooperative navigation in the particle world and adaptive traffic control tasks demonstrate the effectiveness of our method.
