Interacting Effects of Trait Anger and Acute Anger Arousal on Pain: The Role of Endogenous Opioids

Objective: Elevated trait anger (TRANG; heightened propensity to experience anger) is associated with greater pain responsiveness, possibly via associations with deficient endogenous opioid analgesia. This study tested whether acute anger arousal moderates the impact of TRANG on endogenous opioid analgesia. Methods: Ninety-four chronic low back pain (LBP) participants and 85 healthy controls received opioid blockade (8 mg of naloxone) or placebo in a randomized, counterbalanced order in separate sessions. Participants were randomly assigned to undergo either a 5-minute anger recall interview (ARI) or a neutral control interview across both drug conditions. Immediately after the assigned interview, participants engaged sequentially in finger pressure and ischemic forearm pain tasks. Opioid blockade effects were derived (blockade minus placebo condition pain ratings) to index opioid antinociceptive function. Results: Placebo condition TRANG by interview interactions (p values < .05) indicated that TRANG was hyperalgesic only in the context of acute anger arousal (ARI condition; p values < .05). Blockade effect analyses suggested that these hyperalgesic effects were related to deficient opioid analgesia. Significant TRANG by interview interactions (p values < .05) for both pain tasks indicated that elevated TRANG was associated with smaller blockade effects (less endogenous opioid analgesia) only in the ARI condition (p values < .05). Results for ischemic task visual analog scale intensity blockade effects suggested that associations between TRANG and impaired opioid function were most evident in LBP participants when experiencing anger (type by interview by TRANG interaction; p < .05). Conclusions: Results indicate that hyperalgesic effects of TRANG are most prominent when acute anger is aroused and suggest that endogenous opioid mechanisms contribute.TRANG = trait anger; ARI = anger recall interview; NCI = neutral control interview; LBP = low back pain; BDI = Beck Depression Inventory; STAI = State-Trait Anxiety Inventory; MPQ-S = McGill Pain Questionnaire-Sensory subscale; MPQ-A = McGill Pain Questionnaire-Affective subscale; BP = blood pressure; FP = finger pressure; ISC = ischemic.
Optimization of PID Controller Based on Maximization of the Proportional Gain Under Constraints on Robustness and Sensitivity to Measurement Noise

This technical note presents a new, simple and effective, four-parameters proportional-integral-derivative (PID) optimization method. The set of adjustable parameters is defined by the proportional gain k, integral gain ki, damping ratio of the controller zeros (DRCZ), and desired value of the sensitivity to measurement noise Mn. Given Mn and desired value of the maximum sensitivity Ms, for both maximization of k and maximization of ki, only three nonlinear algebraic equations need to be solved for a few values of DRCZ. Contrary to the method based on maximization of ki, in the method based on maximization of k the improvement of performance is obtained by decreasing DRCZ from 1 to the value corresponding to the minimum of the integrated absolute error (IAE). Moreover, this is achieved without deteriorating robustness to the model uncertainties, for a large class of stable processes. Compared to the recently proposed PID optimization methods, for the same Ms and Mn, lower values of IAE and M p are obtained by using the method presented here.
Advantages of FEM analysis in electrical machines optimization used in wind energy conversion systems

The present paper refers to some examples that use the finite element method (FEM) in the process of analysis, design and optimization of the electrical machines used in wind energy conversion systems. The 2D-FEM program Opera 13 of Vector Fields is used in the analyzed examples. These examples refer to two types of synchronous generators with permanent magnets. Some possibilities and advantages of electrical machine optimization, using the FEM-programming packages available today, are pointed out in the present paper.
A Role for the GCC-Box in Jasmonate-Mediated Activation of the PDF1.2 Gene of Arabidopsis1

The PDF1.2 gene of Arabidopsis encoding a plant defensin is commonly used as a marker for characterization of the jasmonate-dependent defense responses. Here, using PDF1.2 promoter-deletion lines linked to the β-glucoronidase-reporter gene, we examined putative promoter elements associated with jasmonate-responsive expression of this gene. Using stably transformed plants, we first characterized the extended promoter region that positively regulates basal expression from the PDF1.2 promoter. Second, using promoter deletion constructs including one from which the GCC-box region was deleted, we observed a substantially lower response to jasmonate than lines carrying this motif. In addition, point mutations introduced into the core GCC-box sequence substantially reduced jasmonate responsiveness, whereas addition of a 20-nucleotide-long promoter element carrying the core GCC-box and flanking nucleotides provided jasmonate responsiveness to a 35S minimal promoter. Taken together, these results indicated that the GCC-box plays a key role in conferring jasmonate responsiveness to the PDF1.2 promoter. However, deletion or specific mutations introduced into the core GCC-box did not completely abolish the jasmonate responsiveness of the promoter, suggesting that the other promoter elements lying downstream from the GCC-box region may also contribute to jasmonate responsiveness. In other experiments, we identified a jasmonate- and pathogen-responsive ethylene response factor transcription factor, AtERF2, which when overexpressed in transgenic Arabidopsis plants activated transcription from the PDF1.2, Thi2.1, and PR4 (basic chitinase) genes, all of which contain a GCC-box sequence in their promoters. Our results suggest that in addition to their roles in regulating ethylene-mediated gene expression, ethylene response factors also appear to play important roles in regulating jasmonate-responsive gene expression, possibly via interaction with the GCC-box.
De la sélection d'arbres de décision dans les forêts aléatoires

Dans cet article nous presentons une etude sur une nouvelle famille de methodes d'Ensembles de Classifieurs, appelee Forets Aleatoires (RF pour Random Forest). Dans un processus d'induction de forets aleatoires "traditionnel", un nombre prealablement fixe d'arbres de decision est genere, a l'aide notamment de principes d'apprentissage partiellement aleatoires. Ce type de processus presente deux principaux inconvenients : i) le nombre d'arbres doit etre fixe a priori ii) l'interpretabilite et les capacites d'analyse offertes par les classifieurs de type arbres de decisions sont perdues, du fait de l'utilisation de principes de "randomisation" au cours de leur induction. Ces constatations soulevent alors deux questions : ce type de forets aleatoires contientelle des arbres de decision qui deteriorent les performances de l'ensemble ? Si oui, ces arbres presentent-ils des proprietes particulieres qui pourraient expliquer cette perte de performances ? Pour repondre a ces questions, nous abordons cette problematique comme un probleme de selection de classifieurs, et montrons que de meilleurs sous-ensembles d'arbres de decision peuvent etre obtenus en utilisant des methodes sous-optimales de selection de classifieurs. Les resultats prouvent notamment qu'un algorithme d'induction de forets aleatoires "classique" n'est pas la meilleure approche pour produire des classifieurs de type forets aleatoires qui soient performants.
Optimal combination of stator and rotor pole numbers in flux-switching PM brushless AC machines

A simple analytical method is developed to compare the combinations of stator and rotor pole numbers in flux-switching PM machines in terms of back-EMF and electromagnetic torque. The winding connections for machines having all poles and alternate poles wound are determined, based on the coil-EMF vectors. The conditions are established for balanced symmetrical back-EMF waveform. It shows that the optimized rotor pole number should be close to the number of stator pole, while larger torque can be obtained by the machine with relatively higher rotor pole number.
Percent Grammatical Responses as a General Outcome Measure: Initial Validity.

Purpose This report investigated the validity of using percent grammatical responses (PGR) as a measure for assessing grammaticality. To establish construct validity, we computed the correlation of PGR with another measure of grammar skills and with an unrelated skill area. To establish concurrent validity for PGR, we computed the correlation of PGR with a previously validated measure of grammaticality, percent grammatical utterances (PGU), and examined the extent to which PGR and PGU agreed upon pass/fail decisions for children. Method Participants included 79 3-year-olds from mostly middle socioeconomic status homes. Language samples were elicited by asking children to describe 15 pictures in response to 4 questions per picture. To calculate PGU, children's responses to all 4 questions were segmented into communication units, and each communication unit was evaluated for grammatical errors. To calculate PGR, the entire response to just the first question was evaluated for grammatical errors. Results PGR scores significantly correlated with a standardized test of grammar (r = .70), but not with a measure of vocabulary (i.e., type-token ratio; r = .11). In addition, PGR scores were significantly correlated with PGU scores (r = .88). Agreement between PGR and PGU was 92% for pass decisions and 94% for fail decisions. Conclusions The current study establishes the construct validity of PGR as a measure of grammar and supports the use of PGR as a measure to assess grammaticality.
Heterolocalism: an alternative model of the sociospatial behaviour of immigrant ethnic communities.

"This paper evaluates critically the applicability of the well-known assimilation and pluralist models to the contemporary ethnic landscape of the U.S. We then consider an alternative model, labelled heterolocalism, which suggests that members of certain newly arrived groups may be able to sustain their identity as an ethnic community despite immediate or rapid spatial dispersion. The applicability of the heterolocal perspective to non-metropolitan and transnational phenomena is evaluated in subsequent sections of the paper. "
Characterization and Modeling of Visible Light Communication Channels

The performance of visible light communication (VLC) system may potentially be degraded by wireless optical channel distortions resulting from path loss and temporal dispersions. In order to devise techniques to combat the effects of channel distortions, an accurate channel model is needed. In this paper, we propose a new field of view (FOV) geometry-based single bounce (GBSB) model for VLC channels. Statistical properties of the proposed GBSB model are then studied, such as the channel gain, mean excess delay, root mean square (RMS) delay spread, Rician factor, and time correlation. Also, the required illuminance for the proposed scenario and the number of light emitting diodes (LEDs) per LED lamp are estimated.
STRUCTURER LE LEXIQUE DE L’ESPAGNOL MOYENNANT DES CLASSES SÉMANTIQUES

In this paper, we present the hierarchy of semantic labels for Spanish that we are building in the frame of the research project FFI2013-44185-P Semantic labels hierarchy for the genus proximum (next kind) of lexicographic definition (UAB). We describe the notions of semantic label and the notion of actantial formula. The semantic label constitutes the syntactic head of the entry’s formal definition. It must be noted that the definiendum almost never corresponds with the entry form (the lemma) but with a propositional form or actant structure (actantial formula) that includes all the semantic actants of the lemma. Semantic labels are actual linguistic signs of Spanish and not a metalinguistic device. This implies that the regular semantic, syntactic and restricted lexical cooccurrence of a given label with the definiendum can and must be controlled before attributing a lemma to it. This control plays a key role in the elaboration of the hierarchy as it is the central criterion for the attribution of a label. Moreover, it is a distinctive trait of our hierarchy since most sets of semantic labels are made up of metalinguistic entities. Labelling in this way we obtain both a minimal paraphrase of the lemma’s signified and a syntactical substitute in any context. It is worth emphasising that our hierarchy of semantic labels is language-dependent. As a result, it cannot be directly used for translation or for multilingual search operations. However, different mechanisms of connections or equivalences between hierarchies can be proposed in order to consider translinguistic applications. We discuss also several mechanisms of semantic description, as the inclusive disjunction, the exclusive disjunction or the fission of variables. One of the questions that we need to address in the future is how to adapt our hierarchy to label not only the nouns but the other parts of speech as well. We illustrate our comments with Spanish examples accompanied with French translations.
A Case of Very Late Bare-Metal Coronary Stent Thrombosis Two Weeks after Aspirin Discontinuation, Histopathologic Thrombus Findings and Clinical Considerations

There have been consistent evidences that atherosclerotic changes occur inside bare metal stents (BMS) during an extended period after implantation. This report describes the histopathologic features of aspirated material harvested from a patient with definite very late stent thrombosis of a BMS implanted 18 years prior. The patient presented with a recurrent anterior acute myocardial infarction 14 day after aspirin discontinuation. We suggest that vulnerable neointimal tissue inside the stent struts of BMS may be one potential trigger of thrombosis when the protection of aspirin treatment is ceased.
Raman scattering of collagen, gelatin, and elastin

The Raman spectra of collagen, gelatin, and elastin are presented. The Raman lines in the latter two spectra are assigned by deuterating the amide N‐H groups in gelatin and by studying the superposition spectra of the constituent amino acids. Two lines appear at 1271 and 1248 cm−1 in the spectra of collagen and gelatin that can be assigned to the amide III mode. Possibly, the appearance of two amide III lines is related to the biphasic nature of the tropocollagen molecule, i.e., proline‐rich (nonpolar) and proline‐poor (polar) regions distributed along the chain. The melting, or collagen‐to‐gelatin transition, in water‐soluble calf skin collagen is studied and the 1248‐cm−1 amide III line is assigned to the 31 helical regions of the tropocollagen molecule.

Vibrio cholerae O1 El Tor cluster in Sydney linked to imported whitebait

Three cases of cholera in women aged 71, 72 and 84 years were notified in November 2006 in Sydney, New South Wales. This is the first reported cluster of cholera in Australia for over 30 years, and was an unusual outbreak in patients with no history of recent travel to cholera‐endemic areas. A food trace‐back investigation found that the only exposure common to all cases was consumption of raw whitebait imported from Indonesia. This outbreak demonstrates that the practice of eating raw whitebait does occur in Australia, albeit in the process of taste‐testing uncooked fritter batter. All three patients were undergoing long‐term therapy with proton‐pump inhibitors, which may have contributed to their susceptibility to the disease. A review of importation practices of food from cholera‐endemic regions may be required to prevent future transmission.
Associations between lower limb impairments, locomotor capacities and kinematic variables in the frontal plane during walking in adults with chronic stroke.

OBJECTIVE The objective was to examine the associations between impairments of the paretic limb, locomotor capacities and kinematic variables in the frontal plane during walking. DESIGN Cross-sectional study. SUBJECTS Ten community-dwelling individuals with chronic hemiparesis due to a cerebrovascular accident. METHODS Frontal plane kinematics of the shoulders and pelvis were assessed during treadmill walking in a gait lab using a videographic system to obtain the lateral displacements and lateral accelerations. The percentages of time spent in single stance were determined with foot-switches. Index of asymmetry for the lateral accelerations and single stance were also calculated. Subject motor and functional characteristics were measured by standardised clinical tests. RESULTS Correlation analyses with Pearson product-moment correlation or Spearman's rank correlation revealed that, except for spasticity, the clinical scores were moderately to strongly associated with frontal kinematics and the single stance. In the multiple step-wise regression analysis, only the pelvic lateral displacements and the index of asymmetry in single stance were explained at more than 70% by the clinical scores with the Time Up and Go test explaining a high proportion of the total variance of these frontal parameters. CONCLUSION Findings demonstrated associations between physical impairments, locomotor capacities and the frontal kinematics in adults with chronic stroke.
RCT of a Comprehensive Outpatient Treatment for Children with Autism Spectrum Disorder

ABSTRACT Objective: This study tested the efficacy of an intensive outpatient psychosocial treatment for children with autism spectrum disorder (ASD) without intellectual disability (ID). Method: Eighty-eight children (ages 7–12 years) were randomly assigned to the treatment or control (waitlist) condition. The 18-week cognitive-behavioral treatment (two 90-min sessions per week) included small-group instruction and therapeutic activities targeting social/social-communication skills, face-emotion recognition, nonliteral language skills, and interest expansion. A behavioral system was used to increase skills development and reduce ASD symptoms. Efficacy was tested immediately following treatment (posttest), with maintenance assessed 4–6 weeks later (follow-up). Measures included parent ratings of the children’s social/social-communication skills, ASD symptoms, broad social skills, and behavior symptoms, child tests of social-cognitive skills (emotion recognition and nonliteral language), and behavioral observations. Results:Significant effects favoring the treatment group were found at posttest on the primary measures of ASD symptoms (Social Responsiveness Scale, Second Edition; Constantino & Gruber, 2012) and social/social-communication skills (Adapted Skillstreaming Checklist; Lopata, Thomeer, Volker, Nida & Lee, 2008), and secondary measures of nonliteral language skills, broad social skills, and behavior symptoms (measures of emotion-recognition skills and social behaviors during structured game sessions were non-significant). The significant treatment effects found at posttest were all maintained at follow-up. Conclusions: The outpatient treatment improved several core areas of functioning for children with ASD without ID. Additional elements may be needed to expand the efficacy of the treatment so that the observed skills/symptom improvements generalize to social interactions during gameplay.
Variability in radiologists' interpretations of mammograms.

BACKGROUND Despite the proved value of mammography in screening for breast cancer, its efficacy depends on radiologists' interpretations. The variability in such interpretations is not well understood. METHODS Using a technique of stratified random sampling, we selected 150 mammograms obtained in 1987: 27 from women with histopathologically confirmed breast cancer and 123 from women with no evidence of breast cancer after three years of follow-up examinations. Ten radiologists, who were unaware of the diagnoses and research hypothesis, each interpreted the 150 mammograms. Disagreement was analyzed within pairs of the 10 radiologists, as well as for the group of 150 women as a whole. RESULTS The diagnostic consistency between pairs of radiologists was moderate, with a median weighted percentage of agreement of 78 percent (weighted kappa, 0.47). The frequency of the radiologists' recommendations for an immediate workup ranged from 74 to 96 percent for mammograms from the women with cancer and from 11 to 65 percent for films from the women without cancer. A substantial disagreement in management recommendations--in which one radiologist recommended routine follow-up and another recommended a biopsy for the same patient--occurred in 3 percent of the pairwise comparisons but in 25 percent of the comparisons for the group of women as a whole. When two or more radiologists recommended a biopsy for the same patient, a disagreement in the stated location (right or left breast) occurred in 2 percent of the pairwise comparisons among the radiologists but in 9 percent of comparisons for the group of women as a whole. Because some disagreement was likely, given that 10 radiologists read each film, the pairwise comparison is a more conservative estimate of disagreement. CONCLUSIONS Although mammography is of value in screening women for breast cancer, radiologists can differ, sometimes substantially, in their interpretations of mammograms and in their recommendations for management. Efforts to improve accuracy and reduce variability in interpretation may increase the effectiveness of mammography in detecting early breast cancers.
