The maintenance of cross-domain associations in working memory

La memoire de travail est le systeme responsable du maintien et traitement des informations simultanement. Nous faisons appel a cette capacite en continu dans notre vie quotidienne. Par exemple, lors d’une conversation, il faut retenir le sujet de la conversation, pendant qu’on continue a traiter de nouvelles informations rajoutees par les interlocuteurs. De nombreuses etudes ont essaye de reveler le fonctionnement de la memoire de travail. La plupart de ces etudes se sont concentrees sur le maintien des informations simples, comme des couleurs ou des formes. Notre environnement est par contre plutot compose d’objets constitues de plusieurs caracteristiques. Dans cette these, nous avons essaye de comprendre comment sont maintenues ces informations associees. Plus specifiquement, nous avons etudie la capacite, les ressources et les representations des informations inter-domaines, composees alors de caracteristiques de differents domaines, comme par exemple le nom d’une ville et sa localisation.
Homology throughout the multiple 32-kilobase circular plasmids present in Lyme disease spirochetes

We have characterized seven different 32-kb circular plasmids carried by Borrelia burgdorferi isolate B31. Restriction endonuclease recognition site mapping and partial sequencing of these plasmids indicated that all seven are probably closely related to each other throughout their lengths and have substantial relationships to cp8.3, an 8.3-kb circular plasmid of B. burgdorferi sensu lato isolate Ip21. With the addition of the seven 32-kb plasmids, this bacterial strain is known to carry at least 10 linear and 9 circular plasmids. Variant cultures of B. burgdorferi B31 lacking one or more of the 32-kb circular plasmids are viable and, at least in some cases, infectious. We have examined a number of different natural isolates of Lyme disease borreliae and found that all of the B. burgdorferi sensu stricto isolates and most of the B. burgdorferi sensu lato isolates tested appear to carry multiple 32-kb circular plasmids related to those of B. burgdorferi B31. The ubiquity of these plasmids suggests that they may be important in the natural life cycle of these organisms. They may be highly conjugative plasmids or prophage genomes, which could prove to be useful in genetically manipulating B. burgdorferi.
Direct isolation of Yersinia enterocolitica and Yersinia pseudotuberculosis from meat

Studies were done to determine the usefulness of dilute alkali (KOH) treatment of meat samples for direct isolation of Yersinia enterocolitica and Yersinia pseudotuberculosis, without enrichment. Virulent Y. enterocolitica and Y. pseudotuberculosis in pork contaminated with 10(2), 10(3), and 10(4) cells per g survived the direct KOH treatment and were never recovered by using KOH postenrichment treatment. From 6 (4.8%) of 125 samples of retail ground pork, four biotype 4 serotype O3 and one biotype 3B serotype O3 strains of Y. enterocolitica and one Y. pseudotuberculosis serotype 4b strain were recovered by using direct KOH treatment without enrichment. As these isolations were attained without using enrichment cultural procedures, they represent an important time-saving alternative to simplify and speed isolation of Yersinia spp. from meat.
Forward Equalizer Decision Feedback Equalizer Σ Noise Predictor-- Steady-State Timing Error Estimator Acquisition Timing Error Estimator Loop

A timing recovery architecture and its CMOS implementation are described for a noise-predictive decisionfeedback equalizer (NPDFE). The 0.5 μm CMOS prototype includes timing recovery and the NPDFE and operates at 160Mbps. The timing recovery blocks dissipate 27mW from 3.3V, occupy 0.2 mm, and achieve a rms jitter of 50 ps, which is0.8% of a bit period.
Can an appraisal model be compatible with psychological constructionism

In this chapter we argue that the account of emotion we proposed in The Cognitive Structure of Emotions (Ortony, Clore, & Collins, 1988) is quite compatible with the psychological constructionist approach to emotion that is the focus of this volume. And we believe this to be true even though our model (now widely referred to as the OCC model) is usually thought of as an appraisal theory. We begin with a brief overview of our model, and then present four sections whose contents relate to the four questions around which the chapters of this book are organized.
Implementation of oscillators circuits by using the GPS technology

Nowadays the world has been assisting a very high competition for the discovery of new advanced technologies, which have demanded an accurate way to implement the modern transmission equipment. One of the most important challenge to be reached is that concerned how to get a reliable precision for generic temporal measurements, in order to preserve an optimal synchronism for both precise continuous time and frequency access. With the actual transition between analog to digital equipment, sometimes we are in front of the important decision about the choice that we can adopt for the hardware implementation, which can preserve the low cost as well as the same facility to obtain all electronic components. In this paper, we present how can we use the synchronism established by the GPS to supply the demanded requirements for the precision, as well as to explore the RF frequency spectrum of an accurate way that permits to preserve both low BER and delay and do not lose many frequencies.
Indexicals and Compositionality: Inside-Out or Outside-In?

Two different approaches to the compositional semantics of indexicals are compared. The outsidein approach uses λ-abstraction and is heavily lexicalised. The inside-out approach treats indexicals by presupposition resolution. The former is relatively simple to implement and deals in a natural way with multiple occurences of indexicals. The latter is more complex, but has potential to deal with a wider range of indexical phenomena. However, it needs to be constrained in a practical implementation as it over-generates.
Sugarcane spatial-temporal monitoring and crop coefficient estimation through NDVI

ABSTRACT The use of satellite images as a complement in irrigation management constitutes a primordial basis in the decision-making process for irrigated agriculture. In this context, the present study aimed to monitor through Normalized Difference Vegetation Index (NDVI) an irrigated sugarcane field belonging to the Mafambisse company, located at the District of Nhamatanda/Sofala, Republic of Mozambique, and establish its relationship with the crop coefficient established by FAO (kcFAO) and fit a regression model to estimate crop coefficient (kc) from the relationship between NDVI and kcFAO. The study was conducted using a series of Sentinel-2A/MSI images, relative to the period from October 2016 to October 2017. Based on the NDVI images generated, it was possible to monitor the sugarcane crop in the field and analyse the sensitivity of the index to its vegetative vigor. A similar pattern was observed between kcFAO profiles and NDVI values, which allowed the adjustment to be performed, demonstrating that this index is an alternative to obtain the crop coefficient.
Crisis telephone consultation for deliberate self-harm patients: Effects on repetition

Background No interventions have been shown to be effective in reducing deliberate self-harm (DSH) repetition in this group of patients as a whole. Aims To investigate the effect on repetition of offering emergency telephone support in a group of hospital-admitted DSH patients. Method Atotal of 827 DSH patients admitted to medical wards were randomly allocated to either control or intervention (green card) groups. In addition to treatment as usual, the intervention group was offered telephone support should any further crises occur. The main outcome measure was DSH repetition within six months of the index event. Results The intervention had no significant effect on the overall DSH repetition rate (odds ratio 1.20, 95% CI 0.82–1.75). Sub-group analysis suggested that response to the intervention differed according to the past history of DSH – subjects with a previous history repeating more often and first-timers appearing to benefit. Conclusions No overall effect of the intervention was shown. Conclusions concerning sub-groups must be regarded as speculative, but they suggest that further assessment of the value of telephone support in first-timer DSH patients is indicated.
The fate of nitrogen in an Acrisol in Zambia under different management practices

A 10-day 15N tracer experiment, using 15N-NO3 and 15N-NH4, was conducted on an Acrisol in Mkushi, Zambia, in a rain-fed maize field. The addition of the 15N label, as either 15N-NO3 or 15N-NH4, was equivalent to 0.1g/m2 with an enrichment of 99.98%, giving no fertilizing effect of the soil. The main objective was to observe how the use of three different management practices; conservation farming (CFN), conservation farming with the addition of 4t biochar/ ha (CFB) and conventional farming (Conv) effected the pathway of nitrogen, especially focusing on the emission of N2O. The results from the 10-day 15N tracer experiment showed that management practice affected the total N uptake in biomass, N2O fluxes, 15N recovery in N2O and mean %loss of label in the soil pack. CFN was found to have the largest loss of label from the soil profile with a mean % loss of 62%, followed by Conv at 54%, while the smallest loss was found in CFB (36%). In coherence with this, the largest proportional uptake of the 15N-NH4 was in CFN>Conv>CFB, and Conv>CFN>CFB for the 15N-NO3. The differences in N uptake did however not have an effect on yield at harvest. Recovery of the added 15N-label in N2O varied from 0.45 -5.9%. No significant difference between management practice in %loss of the label within the measured system. A notably large average flux of N2O (221.28 μg N2O-N/m2/h) was measured from the Conv treated plots and was found to positively correlate to soil pH and KCl extractable N (8.14 mg NO3/kg, 22mg NH4/kg), possibly due to residual fertilizer left on the soil surface. N2O fluxes from CFB (53.3 μg N2O-N/m2/h) and CFN (27.7 μg N2O-N/m2/h) were within range of what was found in similar studies. The source of N2O was assessed by examining the relationship between gross nitrification rates with N2O fluxes, expecting a significant positive relationship if the main N2O emitting process was nitrification and by examining the relationship between AT% 15N excess in the N2O and AT% 15N excess in the KCl extractable NO3, expecting to find a significant positive relationship if the main N2O emitting process was denitrification. Neither relationship was found to be significant, the results for main N2O emitting process were therefore inconclusive.
Coaxial Filters Optimization Using Tuning Space Mapping in CST Studio

This paper deals with the optimization of coaxial filters using Tuning Space Mapping (TSM) method imple- mented to CST environment. The function of fine and coarse model and their link between each other is explained. In addition, supporting macros programmed in VBA language, which are used for maximum efficiency of the optimization from the users point of view, are men- tioned. Macros are programmed in CST and are also used for automatic calibration constants determination and for automatic calibration process between the coarse model and the fine model. The whole algorithm is illustrated on the particular seven-order filter design and optimized results are compared to measured ones.
A Bitcoin Model for Evaluation of Clustering to Improve Propagation Delay in Bitcoin Network

Bitcoin is a digital currency based on peer-to-peer network to propagate and verify transactions. Bitcoin differs from traditional currencies in that, it does not rely on a centralised authority. In this paper, we present a simulation model of Bitcoin peer-to-peer network which is an event based simulation. Large scale measurements of the real Bitcoin network are performed in order to enable a precise parameterisation of the presented simulation model. In addition, we perform validation results revealing that the presented simulation model behaves as close as the real Bitcoin network. Based on the developed simulation model, evaluation of our proposed Bitcoin Clustering Based Super Node (BCBSN) protocol as a mechanism to speed up information propagation in Bitcoin network is presented. Evaluation results show that the presented clustering protocol is able to reduce the transaction propagation delay with a reasonable proportion.
Changes in food neophobia and dietary habits of international students.

BACKGROUND International study is becoming more prevalent, yet aspects such as food neophobia often militate against visiting students consuming a nutritionally balanced diet. The present study aimed to evaluate the extent to which international post-graduate students experience food neophobia, how this might vary by nationality and other demographic characteristics, and how acculturation might manifest itself in students' dietary behaviour. METHODS International students (n = 228) attending a Masters course were invited to complete a validated food neophobia and dietary habits questionnaire during their first week at university. The questionnaire was subsequently re-administered to the same students approximately 4 and 8 months later. RESULTS In total, 226 usable responses were analysed (124, 58 and 44, respectively) for the first, second and final data collection. Perhaps surprisingly, the overall food neophobia scores increased from an mean (SD) initial value of 27.95 (16.95) to 33.67 (33.67) after 3 months, although, when comparing European and Asian students, only the former were significantly different (P < 0.05). Both Asian and European students reported small but not significant changes in their eating habits, although, after 3 months, significantly (P = <0.05) fewer changes were reported. No significant changes were reported in students' perceived healthiness of their diets either by nationality or over time. CONCLUSIONS Understanding the complexities of food neophobia, other aspects of dietary change and at what point these changes might take place in the acculturation process when students arrive in the UK needs to be fully understood if a climate for positive learning is to be established.
Realistic extended target model for track before detect in maritime surveillance

Traditional target tracking algorithms are generally fed a set of thresholded detections under the hypothesis that no more than one detection is generated by each single target. Improvements in modern radar systems have made possible to obtain high resolution data of the targets, making them occupy more than a single resolution cell, and have made necessary to use appropriate Extended Target Tracking (ETT) techniques, since the aforementioned hypothesis is no longer valid. However, these techniques do not often take into account the physical phenomena that are involved in the radar-sea-target system. This paper explores some of the effects involved in the transmission, propagation, backscattering and processing of the radar signal in a maritime environment, that have a crucial importance in ETT. A statistical model that considers the featured effects is developed and tested in a particle filter based Track before Detect (TbD) algorithm. Accounting for physical aspects, good outcomes in both kinematic (i.e. position and velocity) and size (i.e. width and length) estimation can be pointed out using real radar data acquired by a high resolution X-band Marine radar located in the Gulf of La Spezia, Italy.
Sinorhizobium meliloti Fur-Like (Mur) Protein Binds a Fur Box-Like Sequence Present in the mntA Promoter in a Manganese-Responsive Manner

ABSTRACT In Sinorhizobium meliloti, the MurSm protein, a homologue of the ferric uptake regulator (Fur), mediates manganese-dependent regulation of the MntABCD manganese uptake system. In this study, we analyzed MurSm binding to the promoter region of the S. meliloti mntA gene. We demonstrated that MurSm protein binds with high affinity to the promoter region of mntA gene in a manganese-responsive manner. Moreover, the results presented here indicate that two monomers, or one dimer, of MurSm binds the DNA. The binding region was identified by DNase I footprinting analysis and covers a region of about 30 bp long that contains a palindromic sequence. The MurSm binding site, present in the mntA promoter region, is similar to a Fur box; however, manganese-activated MurSm binds a canonical Fur box with very low affinity. Furthermore, the data obtained indicate that MurSm responds to physiological concentrations of manganese.
Knowledge Linking for Online Statistics

The LAWA project investigates large-scale Web (archive) data along the temporal dimension. As a use case, we are studying Knowledge Linking for Online Statistics. Statistic portals such as eurostat's "Statistics Explained" (http://epp.eurostat.ec.europa.eu/statistics_explained/index.php/Main_Page) provide a wealth of articles constituting an encyclopedia of European statistics. Together with its statistical glossary, the huge amount of numerical data comes with a well-defined thesaurus. However, this data is not directly at hands, when browsing Web data covering the topic. For instance, when reading news articles about the debate on renewable energy across Europe after the earthquake in Japan and the Fukushima accident, one would ideally be able to understand these discussions based on statistical evidence. We believe that Internet contents, captured in Web archives and reflected and aggregated in the Wikipedia history, can be better understood when linked with online statistics. To this end, we aim at semantically enriching and analyzing Web (archive) data to narrow and ultimately bridge the gap between numerical statistics and textual media like news or online forums. The missing link and key to this goal is the discovery and analysis of entities and events in Web (archive) contents. This way, we can enrich Web pages, e.g. by a browser plug-in, with links to relevant statistics (e.g. eurostat pages). Raising data analytics to the entity-level also enables understanding the impact of societal events and their perception in different cultures and economies.
Transparent communication management in wireless networks

Wireless networks are characterized by the generally low quality of service (QoS) that they provide. In the face of user mobility between heterogeneous networks, distributed applications designed for the higher and less variable QoS of wired networks have difficulty operating. Proxy systems provide one solution to this problem. By placing an intermediary on the communication path between wired and wireless hosts, communication streams can be manipulated for transmission using the available QoS. However, some applications, can or will not be modified for use with a proxy due to a lack of code or resources. This position paper proposes a new proxy model in which services can be applied to communication streams without interfering with the operation of the associated application or communication protocols. A proxy architecture which supports autonomous and third party control of filters is presented, and a new class of filters that allow transparent modification of packet data is illustrated with a transparency-support filter for TCP.
Evaluation of Unified Model Rainfall Forecasts over the Western Ghats and North East states of India

Abstract. Prediction of heavy rains associated with orography is still a challenge, even for the most advanced state-of-art high-resolution Numerical Weather Prediction (NWP) modeling systems. The aim of this study is to evaluate the performance of UK Met Office Unified Model (UM) in predicting heavy and very heavy rainfall exceeding 80th and 90th percentiles which occurs mainly due to the forced ascent of air parcels over the mountainous regions of the Western Ghats (WGs) and North East (NE) – states of India during the monsoon seasons of 2007 to 2018. Apart from the major upgrades in the dynamical core of UM from New Dynamics (ND) to Even Newer Dynamics for General Atmospheric Modeling of the environment (ENDGame), the horizontal resolution of the model has been increased from 40 km and 50 vertical levels in 2007 to 10 km and 70 vertical levels in 2018. In general, it is expected that the prediction of heavy rainfall events improves with increased horizontal resolution of the model. The evaluation based on verification metrics, including Probability of Detection (POD), False Alarm Ratio (FAR), Frequency Bias (Bias) and Critical Success Index (CSI), indicate that model rainfall forecasts from 2007 to 2018 have improved from 0.29 to 0.38 (CSI), 0.45 to 0.55 (POD) and 0.55 to 0.45 in the case of FAR over WGs for rainfall exceeding the 80th percentile (CAT-1) in the Day-1 forecast. Additionally, the Symmetric Extremal Dependence Index (SEDI) is also used with special emphasis on verification of extreme and rare events. SEDI also shows an improvement from 0.47 to 0.62 and 0.16 to 0.41 over WGs and NE-states during the period of study, suggesting an improved skill of predicting heavy rains over the mountains. It has also been found that the improvement is consistent and comparatively higher over WGs than NE-states.
RADIATION STERILIZATION I

One of the main advantages of sterilizing heatsensitive pharmaceutical preparations by X and gamma radiation lies in the ability of these ionizing radiations to penetrate thick walled packaging materials without inducing radioactivity in the material which is being irradiated (Stanford Research Institute, 1951). This phenomenon is in contrast to the relatively low penetrating power of cathode rays (electrons) and of ultraviolet light (Hink and Johnson, 1951). As the absorption of cathode, X, and gamma radiation is accompanied by a negligible temperature rise (Brasch and Huber, 1948), it may be possible to substitute this technique for the more expensive aseptic procedures now required (Brewer, 1948). A number of investigators have studied the effect of radiation on various types of microorganisms. In the main, these irradiations were carried out with radioactive sources of low intensity, with x-ray machines, or with electron accelerators (Sparrow and Rubin, 1951; Fram et al., 1950; Trump and Van de Graaff, 1948; Brasch and Huber, 1947; Kirsch and Huber, to be published. The recent availability of intense sources (1,000 curie) of radioactive isotopes (Manowitz, 1951) and the potential availability of even more intense radioactive by-products from the atomic energy program make investigation of these new radiation sources of interest.
