Peter Carey’s recent novel shares the concern with ‘unoriginality’ which has become a hallmark of his later fiction. It can actually be argued that, through this new variation on a known theme, he purports to move beyond the clichéd postmodern paradox that authenticities – whether psychological or aesthetic – are always essentially made up, in order to consider the matter from another angle, pondering the perilous moment when an overtly fabricated object somehow mysteriously springs to life. If, as the title suggests, even our most personal emotions can be rationalized in terms of chemical reactions, why then could we not pursue a reverse path of investigation and envisage material reality as the source providing the components for the creation of spirit? This is the subjective context in which the protagonist Catherine, who works as a horologist (clockwork expert) in a London museum, must reconstruct a nineteenth-century mechanical swan suspected by some to be harbouring the soul of its original maker. Interestingly Catherine, herself a die-hard rationalist, finds herself shaken by a devastating bereavement which makes her unusually open to any form of consolation – including the self-indulgence of nostalgia, but also of cocaine and alcohol – which is why she will whole-heartedly embrace the welcome distraction offered by her work of mechanical reconstruction. As part of her attempt to understand the structure of the automaton, she feels that she must immerse herself in the diaries left behind by the commissioner of the work, an Englishman named Henry Brandling animated by his faith that the elaborate toy may release enough energy in his consumptive son, Percy, to save him from his otherwise lethal condition. Thus Carey creates an opening into the rationalist fabric of his protagonist’s present, allowing her to entertain anachronistic fantasies about the life-saving (let alone life-giving) properties of true art. Inasmuch as Catherine’s perusal of the diaries eventually facilitates a circuitous confrontation of her own grief, so that her excursions into the past serve to shore up her fragile sense of a future, the text appears to vindicate its own fantastic claims about the demiurgic, or at least redemptive, powers of art. Perhaps predictably, some reviewers balked in the face of this species of self-promotion, repeating the oft-expressed view that Carey’s fiction, in view of its deliberate straining of the laws of credibility, finally fails to emerge from an enmeshment in its own favoured themes of forgery and imitative inadequacy. The ultimate question asked by the work is then whether it must be seen to be equal to its own promise of transcendence. The present paper, by way of its own descent into the past (and particularly through a comparison with My Life as a Fake which rehearses similar themes), will try to provide an answer, notably by circumscribing the intention of a text in which metafiction assumes a metaphysical dimension possibly unique in Carey’s corpus.

Production scheduling and vehicle routing are two well-studied problems in literature. Although these supply chain functions are interrelated, they are often solved sequentially. This uncoordinated approach can lead to suboptimal solutions. In the current competitive business environment, companies are searching for methods to save costs and improve their service level. Integrating production and distribution scheduling operations can be an approach to improve the overall performance. This paper focuses on integrated production-distribution operational level scheduling problems, which explicitly take into account vehicle routing decisions of the delivery process. Existing literature on integrated production scheduling and vehicle routing problems is reviewed and classified. Both the problem characteristics of mathematical models and the accompanying solution approaches are discussed to identify directions for further research. [less ▲]

This article concerns the treatment of patients’ rights cases in French‐speaking Belgian hospitals by the “mediator”, that is, the person who has the legal duty of dealing with grievances arising from the application of this right of complaint. What happens to a patient’s complaint? This is the question that this article attempts to answer through a report on the “local” organization of mediation ser‐ vices within the hospital. It thus clari es the links and divergences between the formal discourses accompanying the implementation of the mediation function in health care on the one hand, and, on the other hand, the actual practices of media‐ tion determined by the work of mediators in the hospital.

In this paper we study how supervised machine learning could be applied to build simplified models of real-time (RT) reliability management response to the realization of uncertainties. The final objective is to import these models into look-ahead operation planning under uncertainties. Our response models predict in particular the real-time reliability management costs and the resulting reliability level of the system. We tested our methodology on the IEEE-RTS96 benchmark. Among the supervised learning algorithms tested, extremely randomized trees, kernel ridge regression and neural networks appear to be the best methods for this application. Furthermore, by using feature “importances” computed by tree-based ensemble methods, we were able to extract the most relevant variables to predict the response of real-time reliability management, and thus obtain a better understanding of the system properties.

Glutamate is the major excitatory neurotransmitter in the human brain and has a central role in both intrinsic and stimulus-induced activity. We conducted a study in a cohort of healthy, male volunteers in which glutamate levels were measured in the posterior cingulate cortex (PCC) using 1H magnetic resonance spectroscopy at 3T. The advantages of simultaneous electroencephalography and magnetic resonance imaging (EEG-MRI) were exploited and the subjects were measured in the same session and under the same physiological conditions. Diffusion tensor imaging (DTI), functional MRI (fMRI) and EEG were measured in order to investigate the functional and microstructural correlates of glutamate. The concentration of glutamate (institute units) was calculated and those values were tested for correlation with the metrics of resting state fMRI, DTI, and EEG electrical sources. Our results showed that the concentration of glutamate in the PCC had a significant negative correlation with the tissue mean diffusivity in the same area. The analysis of resting state networks did not show any relationship between the concentration of glutamate and the intrinsic activity of the resting state networks. The concentration of glutamate showed a positive correlation with the electrical generators of alpha-1 frequency and a negative correlation with the generators of alpha-2 and beta-1 electrical generators.

The influence of a conducting layer on the magnetic flux penetration in a superconducting Nb film is studied by magneto-optical imaging. The metallic layer partially covering the superconductor provides an additional velocity-dependent damping mechanism for the flux motion that helps protecting the superconducting state when thermomagnetic instabilities develop. If the flux advances with a velocity slower than w = 2/µ0σt, where σ is the cap layer conductivity and t is its thickness, the flux penetration remains unaffected, whereas for incoming flux moving faster than w, the metallic layer becomes an active screening shield. When the metallic layer is replaced by a perfect conductor, it is expected that the flux braking effect will occur for all flux velocities. We demonstrate this effect by investigating Nb samples with a thickness step. Some of the observed features, namely the deflection and the branching of the flux trajectories at the border of the thick centre, as well as the favoured flux penetration at the indentation, are reproduced by time-dependent Ginzburg-Landau simulations.

Cancer cells generally rely on aerobic glycolysis as a major source of energy. Methylglyoxal (MG), a dicarbonyl compound that is produced as a side product during glycolysis, is highly reactive and induces the formation of advanced glycation end-products that are implicated in several pathologies including cancer. All mammalian cells have an enzymatic defense against MG composed by glyoxalases GLO1 and GLO2 that converts MG to d-lactate. Colorectal cancer (CRC) is one of the most frequently occurring cancers with high morbidity and mortality. In this study, we used immunohistochemistry to examine the level of MG protein adducts, in a series of 102 CRC human tumors divided into four clinical stages. We consistently detected a high level of MG adducts and low GLO1 activity in high stage tumors compared to low stage ones suggesting a pro-tumor role for dicarbonyl stress. Accordingly, GLO1 depletion in CRC cells promoted tumor growth in vivo that was efficiently reversed using carnosine, a potent MG scavenger. Our study represents the first demonstration that MG adducts accumulation is a consistent feature of high stage CRC tumors. Our data point to MG production and detoxification levels as an important molecular link between exacerbated glycolytic activity and CRC progression. [less ▲]

This study evaluated the impact of the mother’s and father’s anxiety sensitivity (AS) andlearning experiences on children’s AS, and the influence of two moderators: the children’sfemininity orientation and the children’s emotional intelligence (EI). The samplecomprised 200 non-clinical children, aged 9–13 years, and their parents (mothers andfathers). Results revealed that the effect of parental AS on children’s AS is moderated bythe children’s EI for maternal AS and by their femininity traits for paternal AS. Learningexperiences following somatic sensations influenced the children’s level of AS. Morespecifically, special attention by parents following a child’s somatic sensations (reinforce-ment and transmission of information) was associated with high AS in children. Parentalreactions of fear following a parent’s somatic sensations (modelling) seem to predicthigher scores for AS when the link is moderated by the child’s femininity orientation. Theimplications of these findings are discussed. [less ▲]

Urban groundwater has been over-exploited during the past, mainly for industrial uses, and it now tends to be reduced or abandoned due to pollution and/or changes in land use. The use and the subsequent disuse of groundwater resulted in rising water tables that damage underground structures (e.g., building basements and underground car parks and tunnels), leading to additional pumping in urban areas. This is the case of the underground parking lot of Sant Adrià del Besòs (NE Spain), where large amounts of urban groundwater are pumped to avoid seepage problems. The question that arises here is if this pumped groundwater can be used for other purposes (e.g., drinking water and urban irrigation) instead of wasting this valuable resource. To answer this question, it is necessary to quantify the groundwater recharge and to assess the evolution of ground-water quality in order to properly identify its potential uses. The limiting factor to define the uses of this resource is the groundwater quality because ammonium and some metals (iron and manganese) are present at high concentrations. Hence, further treatment would be needed to meet drinking water requirements. The pumped groundwater could also be used for supplying the ecological river flow and/or for mitigating seawater intrusion problems. Currently, only a small amount of this urban groundwater is used for cleaning public areas and watering public gardens. This situation highlighted the urgent need to manage this resource in a responsible and more efficient manner, especially in moments of high water demand such as drought periods. [less ▲]

Five complexes with the generic formula fac-[MnBr(CO)3(S2C[middle dot]NHC)] were obtained by reacting [MnBr(CO)5] with a set of representative imidazol(in)ium-2-dithiocarboxylate zwitterions. These ligands are the adducts of N-heterocyclic carbenes (NHCs) and carbon disulfide. The mononuclear Mn(i) derivatives were coupled with Na[Mn(CO)5] to afford bimetallic [Mn2(CO)6(S2C[middle dot]NHC)] clusters. Yet, the most convenient strategy to access these dinuclear Mn(0) products implied a direct carbonyl substitution from the [Mn2(CO)10] dimer. The molecular structures of three monometallic and four bimetallic compounds were elucidated by single crystal X-ray diffraction analysis. In the monometallic complexes, the NHC[middle dot]CS2 ligands exhibited a bidentate [small kappa]2-S,S[prime or minute] coordination mode with an S-C-S bite angle of about 116[degree]. In the dinuclear clusters, the CS2- unit acted as a chelate toward one manganese center and as a pseudoallylic ligand toward the other one. The S-C-S bite angle was reduced to ca. 104[degree]. Thus, the zwitterions displayed a remarkable flexibility, which also permitted a staggered arrangement of the carbonyl groups in the bimetallic systems. Examination of the [small nu, Greek, macron]CO absorption bands on IR spectroscopy helped identify the presence of fac-Mn(CO)3 or Mn2(CO)6 motifs, while the 13C NMR chemical shift of the CS2- moiety was a reliable indicator for monitoring its hapticity. Whereas the dinuclear clusters were air- and moisture-stable crystalline solids, mononuclear halido derivatives displayed only a limited stability under aerobic conditions. Both types of compounds underwent rather unselective, extensive fragmentations in the gas phase, in sharp contrast with the analogous rhenium derivatives that led to clean sequential decarbonylation processes upon collision-induced dissociation.

Migration dynamics of incoming eels in Belgium via Lixhe in the Meuse River were investigated using two fish passes with different configurations— net traps and automatic detection stations—as tools to distinguish resident and migrating eels. From April to September 2013, 435 eels (P50 length, 403 mm; range, 196–836 mm) were caught (daily maxima catch, 90 eels per day), 90% between 13 June and 1 August (50 days) and P50 on 19 July. Eels migrated mostly at 19–26 °C (P50, 24.4 °C), river discharge 65–314m3 s 1 (P50, 84m3 s 1), during the dark at 00:00–05:00 h and during both the waxing and waning phases of moonlight. From 396 eels tagged and released 0.3 km downstream of the Lixhe dam, 6.8% of them were recaptured, and 37.4% were detected. Migration flux was estimated at 7184 eels (0.863 t) using the markrecapture method and decreased to 1156 eels (0.139 t) using automatic transponder detection. Most eels probably migrated through a sluice located downstream of Lixhe to reach the upper Meuse via the Albert Canal. Eels moved almost independently to the configuration of the fish passes and their location, but most eels displayed fidelity to the fish pass where they were captured. Migrant eels showed a wide range of size and life stages, with a higher proportion of eels (80%) belonging to the yellow eel stage. A lower proportion of eels (6%) had a larger size and presented an advanced continental silvering process corresponding to the migrating stage before their transatlantic migration.

This paper consists in the description and application of a new method named Wavelet-Induced Mode Extraction (WIME) in the context of time-frequency analysis. WIME aims to extract the oscillating components that build amplitude modulated-frequency modulated signals. The essence of this technique relies on the successive extractions of the dominant ridges of wavelet-based timefrequency representations of the signal under consideration. Our tests on simulated examples indicate strong decomposition and reconstruction skills, trouble-free handling of crossing trajectories in the time-frequency plane, sharp performances in frequency detection in the case of mode-mixing problems and a natural tolerance to noise. These results are compared with those obtained with the Empirical Mode Decomposition. We also show that WIME still gives meaningful results with real-life data, namely the Oceanic Niño Index.
