Conception de systèmes agricoles durables avec couverture herbacée permanente pour les Hauts de la Réunion

Face aux consequences nefastes de la monoculture, les solutions proposees se generalisent, mais developpees en sol nu, elles maintiennent une erosion intense et accroissent les intrants. Sans jachere, la monoculture a conduit a une extreme degradation du milieu. Les outils biologiques, tels que les couvertures vegetales, permettent de reconstruire des systemes stabilises et diversifies. L'efficacite de solutions durables passe entre autre par : 1 un choix d'especes en couverture totale, perennes agressives, faciles a implanter (graminee ou legumineuse) 2 une maitrise de la couverture pour eviter une concurrence avec la culture. Ainsi la couverture reduit la proliferation des adventices et supprime les sarclages. Les rendements sont ameliores sur geranium avec les legumineuse et sur culture maraichere sans apport de fumier. Des consequences favorables sont observes sur le milieu. Dans un environnement protege, ces conditions de production favorables devraient conduire a une diversification et stabilisation des exploitations
Don’t Fear the Bit Flips: Robust Linear Prediction Through Informed Channel Coding

Traditionally, data storage systems provide errorcorrection and data integrity techniques in an independent layer, with the goal of protecting all the data equally regardless of the application. In the context of machine learning systems, this strategy is not appropriate: errors in a few features may prove to be critically important (with respect to the algorithm output), while many errors may have little or no effect. This work takes a different direction: we allow ML algorithms to talk to error-correction schemes, with the goal of making algoritms robust to storage noise. We introduce several novel problems, provide an efficient solution to estimate the noiseinduced change in the algorithm output for linear models, and show how to optimize errorcorrection codes to minimize error effects for fixed overhead.
Effects of structural and environmental parameters on the coupling loss of leaky rectangular waveguide in tunnel

The effects of the structural and environmental parameters on coupling loss of leaky rectangular waveguide in tunnel are studied in this paper, the parameters include the tunnel size and the slot period of leaky waveguide. A new approach based on ray tracing method is proposed for computing the distribution of coupling loss above the upside wall of the leaky waveguide. The approach is verified by comparing the results with those of available method. The results of this paper show that the average value of the coupling loss along the leaky rectangular waveguide fluctuates with the tunnel size, and decreases with increasing of slot period, which are valuable for the design of the leaky rectangular waveguide used in Communications Based Train Control (CBTC) system.
Epithelioid Sarcoma-Like Hemangioendothelioma

We are reporting seven histologically identical cases of a distinctive, low-grade vascular tumor that closely mimics an epithelioid sarcoma because of growth in solid sheets and nests, the eosinophilia of the rounded to slightly spindled neoplastic cells, and the diffuse, strong cytokeratin expression. Termed epithelioid sarcoma-like hemangioendothelioma, all were diagnosed by the submitting pathologist or another expert consultant as epithelioid sarcoma. Although none displayed architectural evidence of vascular differentiation in the form of multicellular vascular channels, some displayed subtle cytologic features of vascular differentiation and all displayed immunohistochemical evidence of endothelial differentiation. The patients (four male; three female) ranged in age from 17 to 54 years (median 23 years). Ranging in size from 1 to 3.5 cm, they occurred in the extremities (n = 5), scalp (n = 1), and chest wall (n = 1), both in deep (n = 3) and superficial (n = 3) soft tissue or both (n = 1). The tumors were characterized by sheets, ill-defined nodules, or fascicles of deeply eosinophilic cells set within a desmoplastic stroma. Multicellular vascular channel formation and/or hemorrhage were absent in all cases. In four cases intracytoplasmic vacuolization suggestive of intracytoplasmic vascular lumen formation was noted. The typical neoplastic cell was large and rounded in shape but modulated in areas to a spindled or multipolar shape. Mitotic activity was low (<5 mitotic figures/50 high power fields), nuclear pleomorphism was mild to moderate, and necrosis was absent. The tumors were positive for cytokeratin (6 of 6), vimentin (6 of 6), CD31 (5 of 6), FLI-1 (6 of 6), but negative for CD34 (0 of 6). Within a follow-up period of 3–72 months (median 39 months), two patients experienced a local recurrence and one patient regional soft tissue metastases, but no distant ones. Two patients presented with multifocal lesions suggestive of regional metastases. Currently, two patients are alive with disease and five are disease free. Epithelioid sarcoma-like hemangioendothelioma appears to be a largely unrecognized epithelioid vascular tumor with an indolent course. Despite its similar clinical and histologic features, it differs from epithelioid sarcoma by the presence of endothelial markers and the absence to date of distant metastases. Its distinction from other epithelioid vascular lesions is discussed. We think this tumor fits best into the family of “hemangioendothelioma” or vascular lesions of intermediate malignancy.
Re-Directing an Alkylating Agent to Mitochondria Alters Drug Target and Cell Death Mechanism

We have successfully delivered a reactive alkylating agent, chlorambucil (Cbl), to the mitochondria of mammalian cells. Here, we characterize the mechanism of cell death for mitochondria-targeted chlorambucil (mt-Cbl) in vitro and assess its efficacy in a xenograft mouse model of leukemia. Using a ρ° cell model, we show that mt-Cbl toxicity is not dependent on mitochondrial DNA damage. We also illustrate that re-targeting Cbl to mitochondria results in a shift in the cell death mechanism from apoptosis to necrosis, and that this behavior is a general feature of mitochondria-targeted Cbl. Despite the change in cell death mechanisms, we show that mt-Cbl is still effective in vivo and has an improved pharmacokinetic profile compared to the parent drug. These findings illustrate that mitochondrial rerouting changes the site of action of Cbl and also alters the cell death mechanism drastically without compromising in vivo efficacy. Thus, mitochondrial delivery allows the exploitation of Cbl as a promiscuous mitochondrial protein inhibitor with promising therapeutic potential.
Nematode and grape rootstock interactions including an improved understanding of tolerance.

Sixteen cultivars of grape were screened over a two-year period in the presence or absence of 10 different nematode populations. Populations of Meloidogyne spp. , Xiphinema index, and Mesocriconema xenoplax developed more rapidly and caused greater damage than populations of X. americanum and Tylenchulus semipenetrans. Populations of mixed Meloidogyne spp. having a history of feeding on grape were among the fastest developing populations. Tolerance to nematode parasitism appeared to be based on different mechanisms. Slow developing, less pathogenic nematode populations often stimulated vine growth, thus vines appeared to possess tolerance. Likewise, cultivars selected for nematode resistance often stimulated vine growth when fed upon by the nematode. However, tolerance sources that resulted from nematode resistance are vulnerable due to the occurrence of populations that break resistance mechanisms. Growth of cultivars with phylloxera (Daktalospharia vitifoliae) resistance was unchanged by the presence of nematodes, indicating that phylloxera resistance may provide a useful source of nematode relief. These and several additional sources of specific tolerance are discussed.
A study of impulsive noise immunity for wavelet-OFDM-based power line communications

In the specification of IEEE P1901-2010, which is the standard for high speed communication devices via electric power lines, two physical layer technologies are defined. One is called fast Fourier transform (FFT)-based orthogonal frequency-division multiplexing (OFDM) and the other is wavelet-based OFDM (Wavelet-OFDM). However, few studies have been discussed the impact of impulsive noise (IN) for Wavelet-OFDM-based PLC systems. This paper preliminarily study the impact of IN on both FFT-OFDM and Wavelet-OFDM-based PLC systems in additive white Gaussian noise (AWGN) channel model. Due to the overlapping in time domain, the Wavelet-OFDM become more prone to IN than the FFT-OFDM.
Behavior Policy Gradient Supplemental Material

A. Proof of Theorem 1 In Appendix A, we give the full derivation of our primary theoretical contribution — the importance-sampling (IS) variance gradient. We also present the variance gradient for the doubly-robust (DR) estimator. We first derive an analytic expression for the gradient of the variance of an arbitrary, unbiased off-policy policy evaluation estimator, OPE(H,θ). Importance-sampling is one such off-policy policy evaluation estimator. From our general derivation we derive the gradient of the variance of the IS estimator and then extend to the DR estimator.
Accuracy of register- and record-based bipolar I disorder diagnoses in Finland; a study of twins

ABSTRACT Registers have been widely used in schizophrenia studies. For bipolar disorder, the use has been more limited and no studies exist concerning accuracy of bipolar I diagnoses in registers. We have collected an unselected twin sample for a study of bipolar I disorder. We report here the diagnostic procedures and accuracy of bipolar I diagnoses in a nation-wide hospital discharge registry. We evaluated also the accuracy of the medical record-based best-estimate diagnoses, comparing these with the SCID interview diagnoses. From the National Hospital Discharge Register we identified all like-sex twins, born 1940-1957, (N=42), and all like- or opposite-sex twins, born 1961-1969, (N=15), who had at least once a diagnosis of bipolar I disorder. The best-estimate diagnoses based on medical records, and were made by two doctors blind to each other, and according to DSM-IV-criteria. Diag-noses were then confirmed by SCID interviews, with the mi-nimum follow-up time after the first admission being 6 years. The accuracy of bipolar diagnoses in the register was 92% and 87%, accordingly. When comparing the best-estimate diagnoses to SCID interview diagnoses, there was one false positive case in the first sample, 3.4% [95% CI 0.1% to 7.8%], and none in the second sample. Our study shows that a diagnosis of bipolar I disorder in the hospital discharge register, or if based only on medical records, is highly reliable and stable. These results strengthen the usefulness of regis-ters also in bipolar disorder.
MATIC: Adaptation and In-situ Canaries for Energy-Efficient Neural Network Acceleration

- The primary author has withdrawn this paper due to conflict of interest - We present MATIC (Memory-Adaptive Training and In-situ Canaries), a voltage scaling methodology that addresses the SRAM efficiency bottleneck in DNN accelerators. To overscale DNN weight SRAMs, MATIC combines specific characteristics of destructive SRAM reads with the error resilience of neural networks in a memory-adaptive training process. PVT-related voltage margins are eliminated using bit-cells from synaptic weights as in-situ canaries to track runtime environmental variation. Demonstrated on a low-power DNN accelerator fabricated in 65nm CMOS, MATIC enables up to 3.3x total energy reduction, or 18.6x application error reduction.
A general method to design dominant negatives to B-HLHZip proteins that abolish DNA binding.

We describe a method to design dominant-negative proteins (D-N) to the basic helix-loop-helix-leucine zipper (B-HLHZip) family of sequence-specific DNA binding transcription factors. The D-Ns specifically heterodimerize with the B-HLHZip dimerization domain of the transcription factors and abolish DNA binding in an equimolar competition. Thermal denaturation studies indicate that a heterodimer between a Myc B-HLHZip domain and a D-N consisting of a 12-amino acid sequence appended onto the Max dimerization domain (A-Max) is -6.3 kcal.mol-1 more stable than the Myc:Max heterodimer. One molar equivalent of A-Max can totally abolish the DNA binding activity of a Myc:Max heterodimer. This acidic extension also has been appended onto the dimerization domain of the B-HLHZip protein Mitf, a member of the transcription factor enhancer binding subfamily, to produce A-Mitf. The heterodimer between A-Mitf and the B-HLHZip domain of Mitf is -3.7 kcal.mol-1 more stable than the Mitf homodimer. Cell culture studies show that A-Mitf can inhibit Mitf-dependent transactivation both in acidic extension and in a dimerization-dependent manner. A-Max can inhibit Myc-dependent foci formation twice as well as the Max dimerization domain (HLHZip). This strategy of producing D-Ns may be applicable to other B-HLHZip or B-HLH proteins because it provides a method to inhibit the DNA binding of these transcription factors in a dimerization-specific manner.
World Federation of Societies of Biological Psychiatry (WFSBP) Guidelines for Biological Treatment of Schizophrenia, Part 2: Update 2012 on the long-term treatment of schizophrenia and management of antipsychotic-induced side effects

Abstract These updated guidelines are based on a first edition of the World Federation of Societies of Biological Psychiatry (WFSBP) guidelines for biological treatment of schizophrenia published in 2006. For this 2012 revision, all available publications pertaining to the biological treatment of schizophrenia were reviewed systematically to allow for an evidence-based update. These guidelines provide evidence-based practice recommendations that are clinically and scientifically meaningful. They are intended to be used by all physicians diagnosing and treating people suffering from schizophrenia. Based on the first version of these guidelines, a systematic review of the MEDLINE/PUBMED database and the Cochrane Library, in addition to data extraction from national treatment guidelines, has been performed for this update. The identified literature was evaluated with respect to the strength of evidence for its efficacy and then categorised into six levels of evidence (A–F) and five levels of recommendation (1–5) (22,b, World J Biol Psychiatry 9:242, see Table I). This second part of the updated guidelines covers long-term treatment as well as the management of relevant side effects. These guidelines are primarily concerned with the biological treatment (including antipsychotic medication and other pharmacological treatment options) of adults suffering from schizophrenia.
Comparison of ACO-OFDM, DCO-OFDM and ADO-OFDM in IM/DD Systems

In this paper, three forms of orthogonal frequency division multiplexing (OFDM) designed for intensity modulated/direct detection (IM/DD) optical systems are compared. These are asymmetrically clipped optical OFDM (ACO-OFDM), DC biased optical OFDM (DCO-OFDM) and asymmetrically clipped DC biased optical OFDM (ADO-OFDM). ADO-OFDM is a new technique that combines aspects of ACO-OFDM and DCO-OFDM by simultaneously transmitting ACO-OFDM on the odd subcarriers and DCO-OFDM on the even subcarriers. The odd subcarriers are demodulated as in a conventional ACO-OFDM receiver and the even subcarriers are demodulated using a form of interference cancellation. ADO-OFDM is shown to be more optically power efficient than conventional ACO-OFDM and DCO-OFDM, for some bit rate/normalized bandwidths. It is also shown that by varying the proportion of optical power on the ACO-OFDM component, the DC bias level of DCO-OFDM and the constellations sent on the odd and even subcarriers, the optical power efficiency of ADO-OFDM can be changed.
Method and theory in American archaeology

In 1958 Gordon R. Willey and Philip Phillips first published Method and Theory in American Archaeology - a volume that went through five printings, the last in 1967 at the height of what became known as the new, or processual, archaeology. The advent of processual archaeology, according to Willey and Phillips, represented a "theoretical debate.a question of whether archaeology should be the study of cultural history or the study of cultural process. " Willey and Phillips suggested that little interpretation had taken place in American archaeology, and their book offered an analytical perspective; the methods they described and the structural framework they used for synthesizing American prehistory were all geared toward interpretation. Method and Theory served as the catalyst and primary reader on the topic for over a decade. This facsimile reprint edition of the original University of Chicago Press volume includes a new foreword by Gordon R. Willey, which outlines the state of American archaeology at the time of the original publication, and a new introduction by the editors to place the book in historical context. The bibliography is exhaustive. Academic libraries, students, professionals, and knowledgeable amateurs will welcome this new edition of a standard-maker among texts on American archaeology.
Multichip Differential Phase-Shift-Keyed Transmission Over (Non)Linear Optical Channels

The recently introduced multichip differential phase-shift keying (MC-DPSK) optical transmission format, entailing the modulation of relative phases over a moving transmission window of successive chip intervals, is analytically and numerically analyzed. The maximum-likelihood optimal MC-DPSK receiver is derived and synthesized using integrated-optic Mach-Zehnder delay interferometers, whose electrical outputs are interpreted as generalized Stokes' parameters. The MC-DPSK performance over a nonlinear fiber channel, limited by the combination of amplified spontaneous emission noise and self-phase modulation, is further derived and simulated, demonstrating that the lowest complexity three-chip binary-phase MC-DPSK receiver provides an ~1-dB Q-factor advantage over conventional DPSK.
CPW-Fed Aperture-Coupled Slot Dipole Antenna for Tri-Band Operation

A uniplanar aperture-coupled slot dipole antenna capable of tri-band operation is presented. Design considerations for the three operating frequencies are extensively discussed. The lower and middle operating frequencies can be obtained by varying the lengths of the lower and middle pairs of the protruded slots, respectively, while the upper frequency can be determined by adjusting the lengths of the upper protruded slot pair and the coupling aperture pair. Within each band, slot-dipole-like radiation patterns, low cross-polarized radiations, and moderate antenna gains can be observed.
Different expression of P14ARF defines two groups of breast carcinomas in terms of TP73 expression and TP53 mutational status

In 95 breast carcinomas, we investigated P14ARF and TP73 mRNA expression and their relationship to TP53 mutations, determined by an immunohistochemical method, studying several clinicopathologic features of the tumors. P14ARF and TP73 mRNA levels were determined by semiquantitative reverse transcription polymerase chain reaction (RT‐PCR), using β‐actin as a control. P14ARF was overexpressed in 19% of the cases and underexpressed in 24%. TP73 was overexpressed in 22% of the tumors, and normal levels were found in the remaining 78%. The analysis of TP53 showed positive immunostaining in 38% of cases. The association of P14ARF and TP73 overexpression was statistically significant, as was the association between positive TP53 staining and TP73 overexpression. P14ARF was related to TP53 only in those cases in which there was low expression of P14ARF. Concomitant overexpression of P14ARF and TP73 was statistically related to positive TP53 immunostaining. The analysis of concomitant P14ARF and TP73 overexpression and clinicopathologic parameters of the tumors showed a statistically significant difference with respect to peritumoral vessel invasion (P = 0.01), lymph node metastasis (P = 0.03), negative ERBB2 expression (P = 0.005), and more advanced pathologic stages (P = 0.03). These results suggest that overexpression of P14ARF and TP73 could be implicated in breast carcinoma tumorigenesis and, ultimately, in the phenotypic features of these lesions. © 2001 Wiley‐Liss, Inc.
Interfacial properties of a carbyne-rich nanostructured carbon thin film in ionic liquid

Nanostructured carbon sp2 (ns-C) thin films with up to 30% of sp-coordinated atoms (carbynes) were produced in a high vacuum by the low kinetic energy deposition of carbon clusters produced in the gas phase and accelerated by a supersonic expansion. Immediately after deposition the ns-C films were immersed in situ in an ionic liquid electrolyte. The interfacial properties of ns-C films in the ionic liquid electrolyte were characterized by electrochemical impedance spectroscopy and cyclic voltammetry (CV). The so-prepared carbyne-rich electrodes showed superior electric double layer (EDL) capacitance and electric conductivity compared to ns-C electrodes containing only sp2 carbon, showing the substantial influence of carbynes on the electrochemical properties of nanostructured carbon electrodes.
Comparison between the SCOFF Questionnaire and the Eating Attitudes Test in patients with eating disorders

Objective: The SCOFF was developed as a simple, five-question screening tool for eating disorders to be used in primary care. The aim of this study was to examine the appropriateness of each question in comparison with the Eating Attitudes Test-26. Methods: The SCOFF and the EAT-26 were administered to 80 patients with eating disorders who had received treatment from May through October 2003 in Japan. Results: The scores of the SCOFF and those of the EAT-26 were positively correlated (P<0.001), and each question of the SCOFF was strongly associated with different items of the EAT-26. The detection rates with the SCOFF of the patients with anorexia nervosa or bulimia nervosa and that of the patients with eating disorders not otherwise specified (EDNOS) were 96.2 and 48.1%, respectively. The scores of the SCOFF and the values of body mass index were significantly correlated (P=0.041), and the detection rate with the SCOFF of patients with low body weight and EDNOS was low (10%). Conclusion: Each question of the SCOFF has been selected appropriately for reflecting characteristics of eating disorders, although one question about body weight loss should be modified to detect patients with anorexia nervosa more accurately.
