Objective: The objective of this paper is to propose, starting from the description of a clinical emblematic case, a theoretical synthesis of the work of phenomenological psychopathology dedicated to melancholia and typus melancholicus (TM), a clinical concept that describes the premorbid personality vulnerable to major depression (“melancholia” for the psychopathological tradition). Method: This is phenomenological analysis of a case study of melancolia, of its premorbid personality and pathogenic triggering situation. We adopt two main phenomenological keys to understanding the develpment of melancholia : role-identity theory and desynchronization theory. The former understands melancholia as a disorder of identity triggered by the loss of the social role with which one has previously over-identifed. The latter sees melancholia as the effect of the desynchronisation from the social environment that further develops into an inhibition of the conative–affective dynamics of life. We present the case of Jonas (64 years old), whose mother (94 years old) recently died. Before his mother’s death, Jonas’ life was entirely orchestrated by the caring for his mother and synchronized in time with this (e.g., he used to go to her house every 4 hours, took all his meals with her, etc.). Jonas, in addition to being hyper-synchronized and hyper-syntonic, fulfills all diagnostic criteria for TM, including “orderliness”, “conscientiousness”, “hyper/heteronomia” and “intolerance of ambiguity”. TM’s attach a disproportioned importance to their social roles (or external representations of identity) at the expense of their own ego-identity. Results: The passage from pre-morbid personality to melancholia is triggered by the death of Jonas’ mother that entails a profound depersonalization. Desynchronization and role loss cause Jonas fall into this severe depersonalization, whose core feature is the feeling of the loss of feeling. Conclusions: This original contribution demonstrates a clinical case can contribute to the construction and refinement of theoretical and conceptual frameworks (like princeps Tellenbach's studies). Over-synchronized tempo and over-identification with social role are emblematically in this case the two sides of the same coin. A parallelism can be established between synchronization (with the mother) and respect for the role at the expense of own identity. The clinical case of Jonas highlights a conceptual bridge between the model of melancholia as loss of social role and the model of melancholia as desynchronization. [less ▲]

Wearable inertial systems often require many sensing units in order to reach an accurate extraction of temporal gait parameters. Reconciling easy and fast handling in daily clinical use and accurate extraction of a substantial number of relevant gait parameters is a challenge. This paper describes the implementation of a new accelerometer-based method that accurately and precisely detects gait events/parameters from acceleration signals measured from only two accelerometers attached on the heels of the subject’s usual shoes. The first step of the proposed method uses a gait segmentation based on the continuous wavelet transform (CWT) that provides only a rough estimation of motionless periods defining relevant local acceleration signals. The second step uses the CWT and a novel piecewise-linear fitting technique to accurately extract, from these local acceleration signals, gait events, each labelled as heel strike (HS), toe strike (TS), heel-off (HO), toe-off (TO), or heel clearance (HC). A stride-by-stride validation of these extracted gait events was carried out by comparing the results with reference data provided by a kinematic 3D analysis system (used as gold standard) and a video camera. The temporal accuracy ± precision of the gait events were for HS: 7.2 ms ± 22.1 ms, TS: 0.7 ms ± 19.0 ms, HO: ‒3.4 ms ± 27.4 ms, TO: 2.2 ms ± 15.7 ms, and HC: 3.2 ms ± 17.9 ms. In addition, the occurrence times of right/left stance, swing, and stride phases were estimated with a mean error of ‒6 ms ± 15 ms, ‒5 ms ± 17 ms, and ‒6 ms ± 17 ms, respectively. The accuracy and precision achieved by the extraction algorithm for healthy subjects, the simplification of the hardware (through the reduction of the number of accelerometer units required), and the validation results obtained, convince us that the proposed accelerometer-based system could be extended for assessing pathological gait (e.g., for patients with Parkinson’s disease).

Smoldering multiple myeloma (SMM) is an asymptomatic clonal plasma cell disorder and bridges monoclonal gammopathyof undeterminedsignificance tomultiplemyeloma(MM), based on higher levels of circulating monoclonal immunoglobulin and bone marrow plasmocytosis without end-organ damage. Until a Spanish study reported fewer MM-related events and better overall survival among patients with highrisk SMM treated with lenalidomide and dexamethasone, prior studies had failed to show improved survival with earlier intervention, although a reduction in skeletal-related events (without any impact on disease progression) has been described with bisphosphonate use. Risk factors have now been defined, and a subset of ultra-high-risk patients have been reclassified by the International Myeloma Working Group asMM, and thus will require optimalMMtreatment, based on biomarkers that identify patients with a.80% risk of progression. The number of these redefined patients is small (∼10%), but important to unravel, because their risk of progression to overt MM is substantial ($80% within 2 years). Patients with a high-risk cytogenetic profile are not yet considered for early treatment, because groups are heterogeneous and risk factors other than cytogenetics are deemed to weight higher. Because patients with ultra-highrisk SMM are now considered as MMand may be treated as such, concerns exist that earlier therapy may increase the risk of selecting resistant clones and induce side effects and costs. Therefore, an even more accurate identification of patients who would benefit from interventions needs to be performed, and clinical judgment and careful discussion of pros and cons of treatment initiation needs to be undertaken. For the greater majority ofSMMpatients, the standard of care remains observation until development of symptomatic MM occurs, encouraging participation in ongoing and upcoming SMM/early MM clinical trials, as well as consideration of bisphosphonate use in patients with early bone loss.

The plant root system traverses one of the most complex environments on earth. Understanding how roots support plant life on land requires knowing how soil properties affect the availability of nutrients and water and how roots manipulate the soil environment to optimize acquisition of these resources. Imaging of roots in soil allows the integrated analysis and modeling of environmental interactions occurring at micro- to macroscales. Advances in phenotyping of root systems is driving innovation in cross-platformcompatible methods for data analysis. Root systems acclimate to the environment through architectural changes that act at the root-type level as well as through tissue-specific changes that affect the metabolic needs of the root and the efficiency of nutrient uptake. A molecular understanding of the signaling mechanisms that guide local and systemic signaling is providing insight into the regulatory logic of environmental responses and has identified points where crosstalk between pathways occurs. Expected final online publication date for the Annual Review of Plant Biology Volume 67 is April 29, 2016. Please see http://www.annualreviews.org/catalog/pubdates.aspx for revised estimates.

Saccharides released after an in vitro pepsin-pancreatin digestion of corn flour were quantified and characterized using high-performance anion-exchange chromatography coupled with a pulsed amperometric detector (HPAEC-PAD) and two colorimetric approaches (glucose oxidase/ peroxidase assay and the 3,5-dinitrosalicylic acid assay). HPAEC-PAD revealed five major saccharides as the result of in vitro pepsin-pancreatin digestion of corn grain: glucose, isomaltose, maltose, maltotriose, and glucosyl-maltotriose. Concentrations of glucose released as measured by the three methods assessed are similar when the in vitro pepsin-pancreatin digestion is followed by post incubation with amyloglucosidase. This post incubation unfortunately leads to a loss of information about the degree of polymerization of oligosaccharides that can impact their absorption through intestinal tract. HPAEC-PAD gives both qualitative and quantitative information and then seems more suitable for a nutritional appreciation of the digestion of starchy feedstuffs. [less ▲]

A great majority of widely used ferrite ceramics exhibit a relatively high temperature of order–disorder phase transition in their magnetic subsystem. For applications related to the magnetization process of superconductors, however, a low value of Tc is required. Here we report and analyze in detail the thermal properties of bulk Ti-doped Cu–Zn ferrite ceramics Cu0.3Zn0.7Ti0.04Fe1.96O4 and Mg0.15Cu0.15Zn0.7Ti0.04Fe1.96O4. They are characterized by a Curie temperature in the range 120–170 K and a maximum DC magnetic susceptibility exceeding 20 for the Cu0.3Zn0.7Ti0.04Fe1.96O4 material. The temperature dependence of both the specific heat Cp and of the thermal conductivity κ, determined between 2 and 300 K, are found not to exhibit any peculiar feature at the magnetic transition temperature. The low-temperature dependence of both κ and the mean free path of phonons suggests a mesoscopic fractal structure of the grains. From the measured data, the characteristics of thermally actuated waves are estimated. The low magnetic phase transition temperature and suitable thermal parameters make the investigated ferrite ceramics applicable as magnetic wave producers in devices designed for magnetization of high-temperature superconductors.

The dominant model of energy infrastructure has historically been conceived in a very centralized fashion, i.e. with hardly any citizen involvement in energy generation. Yet, increasing attention is being paid to the transition process towards a more decentralized configuration. This article examines the factors likely to foster citizen and community participation as regards wind power cooperatives in Denmark, Germany, Belgium and the UK. Using Elinor Ostrom’s Social-Ecological System Framework, the analysis highlights a double-edged phenomenon: prevailing and growing hostility towards cooperatives, on the one hand, and, on the other, strategic reactions to this evolution. What comes out indeed is that, throughout most of these countries, the emergence of some coordinated inter-organizational actions among cooperatives enables them to survive in their critical environment.

Description of the subject. Alginate beads that release semiochemical compounds are interesting biological control devices used to attract the natural enemies of aphids in infested crops. Little information, however, is available about the impact of climatic factors on the release of semiochemicals from this diffusive system. Objectives. The objective of this scoping study was to investigate the impact of temperature, relative humidity and wind speed, on the release of E-β-caryophyllene from alginate beads. Method. The impact of the three climatic factors on the release of E-β-caryophyllene from alginate beads was evaluated using a Box-Behnken experimental design and a laboratory scale volatile collection system. The influence of relative humidity on bead water content and size, with and without this semiochemical, was also investigated using a gravimetric method and an easy-to-use photographic device, respectively. Results. The results showed that an increase in temperature caused a significant increase in the E-β¬-caryophyllene release rate. Neither relative humidity nor airflow, however, had a significant effect on the release of this semiochemical when relative humidity and wind speed ranged from 33% to 75% and from 6.61 x10-4 m.s-1 to 2.05 x10-2 m.s-1, respectively. The isotherm curves obtained were characteristic of food products and biopolymer materials. The isotherm shapes were not modified by the incorporation of the semiochemical into alginate beads, and showed an important increase in water content when relative humidity values exceeded 85%. Fortunately, this water content increase did not affect bead size, which facilitates the calculation of E-β-caryophyllene release. Conclusion. The present study shows for the first time the impact of the three main climatic factors on the release of E-β-caryophyllene from alginate beads. It allows learning more about how these biological control devices operate in order to optimize future field trials. [less ▲]

In the context of chemical ecology, the analysis of the temporal production pattern of volatile organic compounds (VOCs) in root tissues and the emission rate measurement of root-emitted VOCs are of major importance for setting up experiments to study the implication of these compounds in biotic interactions. Such analyses, however, remain challenging because of the belowground location of plant root systems. In this context, this study describes the evolution of the root VOC production pattern of barley (Hordeum distichon L.) at five developmental stages from germination to the end of tillering and evaluates the emission of the identified VOCs in an artificial soil. VOCs produced by crushed root tissues and released by unexcavated root systems were analysed using dynamic sampling devices coupled to a gas chromatography-mass spectrometry methodology (synchronous SCAN/SIM). The results showed that, at each analysed developmental stage, crushed barley roots produced mainly four volatile aldehydes: hexanal; (E)-hex-2-enal; (E)-non-2-enal; and (E,Z)-nona-2,6-dienal. Higher total and individual VOC concentrations were measured in 3-day-old seminal roots compared with older phenological stages. For each developmental stage, the lipoxygenase (LOX) activity was greater for linoleic acid than α-linolenic acid and the greatest LOX activities using linoleic and α- linolenic acids as substrates were measured in 7- and 3-day-old roots, respectively. The analysis of VOCs released by barley roots into the soil showed that (E)-non-2- enal and (E,Z)-nona-2,6-dienal were the only VOCs emitted in quantifiable amounts by mechanically injured roots.

Introduction. In a world that seeks to break free from petrochemicals, the concept of forest biomass biorefinery is increasingly being studied as a way to maximize the value of the components of this biomass. Due to the high added value expected when transforming cellulose fibers into nanocellulose, this technology is highly attractive to the pulp and paper industrial world. Literature. The concept of integrated forest biorefinery is to adapt existing pulp mills so as to maximize the value of the co-products. Through the use of various methods, two types of nanocellulose may be obtained from the cellulose in the pulp. Due to its production of valuable byproducts, enzymatic hydrolysis is an interesting method to use for this purpose, but it must be combined with mechanical post-treatments. The production of nanocellulose from chemical pulp takes place in the final step of pulp production, and could be implemented without modifying the existing mills. The economic viability of this mode of production and the potential market size are the subject of recent studies that appear encouraging. Conclusions. Nanocellulose is a promising biomaterial whose field of application continues to grow. Cellulose in wood pulp can be used as a raw material for the production of nanocellulose using enzymatic pre-treatments that generate valuable co-products. This process can be integrated into a conventional chemical pulp mill and constitutes a broadening of the products available to the pulp and paper industry. [less ▲]
