Psychiatric power: A personal view
Authors: Bracken Pat
Published: March 2016

One of the most important questions facing psychiatry today concerns its relationship to the emerging international service user movement. I believe that this movement presents not only the greatest challenge to psychiatry, but also the greatest opportunity. As it becomes more organised and influential this movement is starting to play a major role in shaping the sort of questions that are being asked about mental health services and their priorities. Yet there is limited reflection in our profession about how we, as doctors, might engage positively with it. It seems that while we are comfortable working with individuals and organisations who accept the medical framing of mental problems, we are less willing to contemplate working with critical service users. These are people who reject the medical model because they feel harmed by a system that describes their problems using the language of psychopathology. If we are serious about having an inclusive debate on mental health we will have to overcome this impasse. We need to entertain the idea that people who reject the medical framing of their problems are nevertheless legitimate stakeholders. It is time that we learned how to talk to them and to listen to their ideas. The user movement, with its substantial critical component, is not going to go away.

One of the most important elements of the relationship between psychiatric services and the people who use them is the reality of psychiatric power. Many critical service users accept that legally sanctioned interventions may be necessary when individuals lose capacity to care for themselves and perhaps put themselves or others at risk. However they do not accept the fact that the Mental Health Act in Ireland gives sole authority to doctors to take decisions on such interventions without any obligation to consult other interested parties.

Textured Voices and the Performance of Ethical Life in the Case of the Laff Box (1966)
Authors: McCARTHY DAVID
Published: March 2016

Textured voices include both voices heard as interpolated into a musical texture and voices heard as having their own textured character, whether as a ‘voice’ with a ‘timbre’ or as a ‘collective voice’ with a ‘composite timbre’ made up of many voices, each textured itself. They have often been heard as performances of ethical life. Comparisons between these performances can be misleading because the contingencies characterizing the textured voice for a listener who listens in a particular way can make each performance irreducible. A pair of articles and cartoons inTV Guidefrom the summer of 1966 depict the making of a textured laugh track as a contradictory activity. Yet they seem to resolve contradictions into surface conflicts between individuated parties. Listening for textured voices in this case was itself a political activity because it was productive of more than one distinct form of ethical life.
Do Cardiovascular Responses to Active and Passive Coping Tasks predict Future Blood Pressure over a 10-Month Later?
Authors: Yuenyongchaiwat Kornanong , Baker Ian , Maratos Frankie , Sheffield David
Published: March 2016

The study examined whether cardiovascular responses to active or passive coping tasks and single or multiple tasks predicted changes in resting blood pressure (BP) over a ten-month period. Heart rate (HR), BP, cardiac output (CO), and total peripheral resistance (TPR) were measured at rest, and during mental stress tests (mental arithmetic, speech, and cold pressor tasks). A total of 104 eligible participants participated in the initial study, and 77 (74.04%) normotensive adult participants’ resting BP were re-evaluated at ten-month follow-up. Regression analyses indicated that after adjustment for baseline BP, initial age, gender, body mass index, family history of cardiovascular disease, and current cigarette smoking, heighted systolic blood pressure (SBP) and HR responses to an active coping task (mental arithmetic) were associated with increased future SBP (ΔR2= .060, ΔR2= .045, respectively). Further, aggregated SBP responsivity (over the three tasks) to the predictor models resulted in significant, but smaller increases in ΔR2accounting for .040 of the variance of follow-up SBP. These findings suggest that cardiovascular responses to active coping tasks predict future SBP. Further, compared with single tasks, the findings revealed that SBP responses to three tasks were less predictive compared to an individual task (i.e., mental arithmetic). Of importance, hemodynamic reactivity (namely CO and TPR) did not predict future BP suggesting that more general psychophysiological processes (e.g., inflammation, platelet aggregation) may be implicated, or that BP, but not hemodynamic reactivity may be a marker of hypertension.

Authors: Vögeli Samuel , Frei Irena Anna , Spichiger Elisabeth
Published: March 2016

Zusammenfassung. Hintergrund: Knapp zwei Drittel der 110 000 Menschen mit Demenz werden in der Schweiz zu Hause von ihren Angehörigen betreut. Zugehende Beratung kann die Belastung der Angehörigen reduzieren und den Heimeintritt verzögern. Es ist noch kaum bekannt, wie dies geschieht und wie Angehörige diese Beratung erleben. Die Alzheimervereinigung Kanton Aargau führt ein Pilot-Projekt durch, um Bedarf, Wirksamkeit und Umsetzbarkeit dieses Angebots aufzuzeigen. Ziel: Als Teil der Projektevaluation wurde in dieser Studie untersucht, wie Angehörige die Betreuung eines Menschen mit Demenz und Zugehende Beratung erleben. Methode: Mit einem qualitativen Ansatz, der interpretierenden Phänomenologie, wurden die Daten aus leitfadengestützten Interviews mit zwölf Angehörigen von Menschen mit Demenz analysiert. Ergebnisse: Die meisten befragten Angehörigen fühlten sich durch die Zugehende Beratung in ihrer Aufgabe unterstützt. Es war ihnen wichtig, von der Beraterin ernst genommen und verstanden zu werden, Antworten auf ihre drängendsten Fragen rund um die Krankheit zu erhalten, bei schwierigen Entscheidungen unterstützt zu werden, wieder mehr Zeit für sich selbst zu gewinnen sowie im Alltag mit der Person mit Demenz besser umgehen zu lernen. Zwei Teilnehmende hätten sich mehr Hilfe von der Beraterin erhofft. Schlussfolgerungen: Um den Bedürfnissen der Angehörigen gerecht werden zu können, sollten Berater(innen) Erfahrung in der Betreuung von Menschen mit Demenz haben und regional stark vernetzt sein. Diese Studie zeigt, dass Angehörige Zugehende Beratung als eine große Unterstützung in ihrer Rolle als Betreuende erleben können.
Personality and Life Satisfaction Over 12 Years
Authors: Tauber Benjamin , Wahl Hans-Werner , Schröder Johannes
Published: March 2016

Abstract. Both theoretical reasoning and empirical data suggest that personality and well-being have substantial interrelationships. However, more longitudinal evidence is required, and the relationship lacks research attention from a lifespan perspective. We examined the mid-term and long-term interrelations of Neuroticism and Extraversion with life satisfaction in two cohorts from middle and late adulthood, using data from the “Interdisciplinary Longitudinal Study of Adult Development (ILSE).” Multigroup, cross-lagged models reveal personality to be more predictive of life satisfaction than vice versa. Furthermore, an aging effect occurs regarding the relationships between life satisfaction and personality, with life satisfaction being predictive of personality only in the old cohort. Controlling for health weakens the interrelationship. Results add to the understanding of lifespan dynamics among personality and life satisfaction.
Coexistence of charge and ferromagnetic order in fcc Fe

Published: March 2016

Phase coexistence phenomena have been intensively studied in strongly correlated materials where several ordered states simultaneously occur or compete. Material properties critically depend on external parameters and boundary conditions, where tiny changes result in qualitatively different ground states. However, up to date, phase coexistence phenomena have exclusively been reported for complex compounds composed of multiple elements. Here we show that charge- and magnetically ordered states coexist in double-layer Fe/Rh(001). Scanning tunnelling microscopy and spectroscopy measurements reveal periodic charge-order stripes below a temperature of 130 K. Close to liquid helium temperature, they are superimposed by ferromagnetic domains as observed by spin-polarized scanning tunnelling microscopy. Temperature-dependent measurements reveal a pronounced cross-talk between charge and spin order at the ferromagnetic ordering temperature about 70 K, which is successfully modelled within an effective Ginzburg–Landau ansatz including sixth-order terms. Our results show that subtle balance between structural modifications can lead to competing ordering phenomena.

We previously produced pigs with a latent oncogenic TP53 mutation. Humans with TP53 germline mutations are predisposed to a wide spectrum of early-onset cancers, predominantly breast, brain, adrenal gland cancer, soft tissue sarcomas and osteosarcomas. Loss of p53 function has been observed in >50% of human cancers. Here we demonstrate that porcine mesenchymal stem cells (MSCs) convert to a transformed phenotype after activation of latent oncogenic TP53R167H and KRASG12D, and overexpression of MYC promotes tumorigenesis. The process mimics key molecular aspects of human sarcomagenesis. Transformed porcine MSCs exhibit genomic instability, with complex karyotypes, and develop into sarcomas on transplantation into immune-deficient mice. In pigs, heterozygous knockout of TP53 was sufficient for spontaneous osteosarcoma development in older animals, whereas homozygous TP53 knockout resulted in multiple large osteosarcomas in 7–8-month-old animals. This is the first report that engineered mutation of an endogenous tumour-suppressor gene leads to invasive cancer in pigs. Unlike in Trp53 mutant mice, osteosarcoma developed in the long bones and skull, closely recapitulating the human disease. These animals thus promise a model for juvenile osteosarcoma, a relatively uncommon but devastating disease.

Published: March 2016

Altered atmospheric circulation, reductions in Arctic sea ice, ocean warming, and changes in evaporation and transpiration are driving changes in the global hydrologic cycle. Precipitation isotopic (δ18O and δ2H) measurements can help provide a mechanistic understanding of hydrologic change at global and regional scales. To study the changing water cycle in the northeastern US, we examined the longest (1968–2010) record of precipitation isotope values, collected at the Hubbard Brook Experimental Forest in New Hampshire, US (43o56′N, 71o45′W). We found a significant reduction in δ18O and δ2H values over the 43-year record, coupled with a significant increase ind-excessvalues. This gradual reduction in δ18O and δ2H values unexpectedly occurred during a period of regional warming. We provide evidence that these changes are governed by the interactions among the Atlantic Multidecadal Oscillation, loss of Arctic sea ice, the fluctuating jet stream, and regular incursions of polar air into the northeastern US.
Mechanism and modulation of terahertz generation from a semimetal - graphite

Published: March 2016

Semi-metals might offer a stronger interaction and a better confinement for terahertz wave than semiconductors, while preserve tunability. Particularly, graphene-based materials are envisioned as terahertz modulators, filters and ultra-broadband sources. However, the understanding of terahertz generation from those materials is still not clear, thus limits us recognizing the potential and improving device performances. Graphite, the mother material of graphene and a typical bulk semi-metal, is a good system to study semi-metals and graphene-based materials. Here we experimentally modulate and maximize the terahertz signal from graphite surface, thus reveal the mechanism - surface field driving photon induced carriers into transient current to radiate terahertz wave. We also discuss the differences between graphite and semiconductors; particularly graphite shows very weak temperature dependency from room temperature to 80 °C. Above knowledge will help us understand terahertz generations, achieve maximum output and electric modulation, in semi-metal or graphene based devices.

The hypoxic tumour microenvironment represents an aggressive, therapy-resistant compartment. As arginine is required for specific hypoxia-induced processes, we hypothesised that arginine-deprivation therapy may be useful in targeting hypoxic cancer cells. We explored the effects of the arginine-degrading agent ADI-PEG20 on hypoxia-inducible factor (HIF) activation, the hypoxia-induced nitric oxide (NO) pathway and proliferation using HCT116 and UMUC3 cells and xenografts. The latter lack argininosuccinate synthetase (ASS1) making them auxotrophic for arginine. In HCT116 cells, ADI-PEG20 inhibited hypoxic-activation of HIF-1α and HIF-2α, leading to decreased inducible-nitric oxide synthase (iNOS), NO-production, and VEGF. Interestingly, combining hypoxia and ADI-PEG20 synergistically inhibited ASS1. ADI-PEG20 inhibited mTORC1 and activated the unfolded protein response providing a mechanism for inhibition of HIF and ASS1. ADI-PEG20 inhibited tumour growth, impaired hypoxia-associated NO-production, and decreased vascular perfusion. Expression of HIF-1α/HIF-2α/iNOS and VEGF were reduced, despite an increased hypoxic tumour fraction. Similar effects were observed in UMUC3 xenografts. In summary, ADI-PEG20 inhibits HIF-activated processes in two tumour models with widely different arginine biology. Thus, ADI-PEG20 may be useful in the clinic to target therapy-resistant hypoxic cells in ASS1-proficient tumours and ASS1-deficient tumours.
Investigation and Manipulation of Different Analog Behaviors of Memristor as Electronic Synapse for Neuromorphic Applications
Authors: Wang Changhong , He Wei , Tong Yi , Zhao Rong
Published: March 2016

Low-power and high-density electronic synapse is an important building block of brain-inspired systems. The recent advancement in memristor has provided an opportunity to advance electronic synapse design. However, a guideline on designing and manipulating the memristor’s analog behaviors is still lacking. In this work, we reveal that compliance current (Icomp) of electroforming process played an important role in realizing a stable analog behavior, which is attributed to the generation of conical-type conductive filament. A proper Icomp could result in a large conductance window, good stability and low voltage analog switching. We further reveal that different pulse conditions can lead to three analog behaviors, where the conductance changes in monotonic increase, plateau after initial jump and impulse-like shape, respectively. These behaviors could benefit the design of electronic synapse with enriched learning capabilities. This work will provide a useful guideline for designing and manipulating memristor as electronic synapses for brain-inspired systems.

Published: March 2016

Interleukin 6 (IL-6) has been shown to be an important regulator of cardiac interstitial fibrosis. In this study, we explored the role of interleukin-6 in the development of diabetic cardiomyopathy and the underlying mechanisms. Cardiac function of IL-6 knockout mice was significantly improved and interstitial fibrosis was apparently alleviated in comparison with wildtype (WT) diabetic mice induced by streptozotocin (STZ). Treatment with IL-6 significantly promoted the proliferation and collagen production of cultured cardiac fibroblasts (CFs). High glucose treatment increased collagen production, which were mitigated in CFs from IL-6 KO mice. Moreover, IL-6 knockout alleviated the up-regulation of TGFβ1 in diabetic hearts of mice and cultured CFs treated with high glucose or IL-6. Furthermore, the expression of miR-29 reduced upon IL-6 treatment, while increased in IL-6 KO hearts. Overexpression of miR-29 blocked the pro-fibrotic effects of IL-6 on cultured CFs. In summary, deletion of IL-6 is able to mitigate myocardial fibrosis and improve cardiac function of diabetic mice. The mechanism involves the regulation of IL-6 on TGFβ1 and miR-29 pathway. This study indicates the therapeutic potential of IL-6 suppression on diabetic cardiomyopathy disease associated with fibrosis.
The Empathizing-Systemizing Theory, Social Abilities, and Mathematical Achievement in Children
Authors: Escovar Emily , Rosenberg-Lee Miriam , Uddin Lucina Q. , Menon Vinod
Published: March 2016

The Empathizing-Systemizing (E-S) theory describes a profile of traits that have been linked to autism spectrum disorders, and are thought to encompass a continuum that includes typically developing (TD) individuals. Although systemizing is hypothesized to be related to mathematical abilities, empirical support for this relationship is lacking. We examine the link between empathizing and systemizing tendencies and mathematical achievement in 112 TD children (57 girls) to elucidate how socio-cognitive constructs influence early development of mathematical skills. Assessment of mathematical achievement included standardized tests designed to examine calculation skills and conceptual mathematical reasoning. Empathizing and systemizing were assessed using the Combined Empathy Quotient-Child (EQ-C) and Systemizing Quotient-Child (SQ-C). Contrary to our hypothesis, we found that mathematical achievement was not related to systemizing or the discrepancy between systemizing and empathizing. Surprisingly, children with higher empathy demonstrated lower calculation skills. Further analysis using the Social Responsiveness Scale (SRS) revealed that the relationship between EQ-C and mathematical achievement was mediated by social ability rather than autistic behaviors. Finally, social awareness was found to play a differential role in mediating the relationship between EQ-C and mathematical achievement in girls. These results identify empathy, and social skills more generally, as previously unknown predictors of mathematical achievement.

Published: March 2016

Osteoarthritis (OA) is a degenerative disease characterized by deterioration of articular cartilage. Recent studies have demonstrated the importance of some microRNAs in cartilage damage. The aim of this study was to identify and characterize the expression of microRNA-634 (miR-634) in normal and OA chondrocytes, and to determine its role in OA pathogenesis. Human normal and OA chondrocytes obtained from patients were cultured in vitro. Transfection with miR-634 mimic or inhibitor was employed to investigate the effect of miR-634 on chondrocyte survival and matrix synthesis, and to identify miR-634 target. The results indicated that miR-634 was expressed at lower level in high grade OA chondrocyte compared with normal chondrocytes. Overexpression of miR-634 could inhibit cell survival and matrix synthesis in high grade OA chondrocytes. Furthermore, miR-634 targeted PIK3R1 gene that encodes the regulatory subunit 1 of class I PI3K (p85α) and exerted its inhibitory effect on the phosphorylation of Akt, mTOR, and S6 signal molecules in high grade OA chondrocytes. Therefore, the data suggested that miR-634 could suppress survival and matrix synthesis of high grade OA chondrocytes through targeting PIK3R1 gene to modulate the PI3K/Akt/S6 and PI3K/Akt/mTOR/S6 axes, with important implication for validating miR-634 as a potential target for OA therapy.
Visual straight-ahead preference in saccadic eye movements
Authors: Camors Damien , Trotter Yves , Pouget Pierre , Gilardeau Sophie , Durand Jean-Baptiste
Published: March 2016

Ocular saccades bringing the gaze toward the straight-ahead direction (centripetal) exhibit higher dynamics than those steering the gaze away (centrifugal). This is generally explained by oculomotor determinants: centripetal saccades are more efficient because they pull the eyes back toward their primary orbital position. However, visual determinants might also be invoked: elements located straight-ahead trigger saccades more efficiently because they receive a privileged visual processing. Here, we addressed this issue by using both pro- and anti-saccade tasks in order to dissociate the centripetal/centrifugal directions of the saccades, from the straight-ahead/eccentric locations of the visual elements triggering those saccades. Twenty participants underwent alternating blocks of pro- and anti-saccades during which eye movements were recorded binocularly at 1 kHz. The results confirm that centripetal saccades are always executed faster than centrifugal ones, irrespective of whether the visual elements have straight-ahead or eccentric locations. However, by contrast, saccades triggered by elements located straight-ahead are consistently initiated more rapidly than those evoked by eccentric elements, irrespective of their centripetal or centrifugal direction. Importantly, this double dissociation reveals that the higher dynamics of centripetal pro-saccades stem from both oculomotor and visual determinants, which act respectively on the execution and initiation of ocular saccades.

Linear minimum mean‐square estimation for discrete‐time measurement‐delay systems with multiplicative noise and Markov jump
Authors: Song Xinmin , Park Ju H.
Published: March 2016

This study addresses the estimation problem for discrete‐time measurement‐delay systems with multiplicative noise and Markov jump. First, the state equation is converted into two equations according to the geometric arguments and flexible transformations. Then, based on the reorganised innovation approach, the finite‐horizon linear minimum mean‐square‐error estimator is derived in terms of two Riccati difference equations and two Lyapunov difference equations. Finally, under the assumptions of mean square stability of the system and ergodicity of the associated Markov chain, a sufficient condition for the existence of the infinite‐horizon estimator is presented. We provide a numerical example to manifest the efficiency of the proposed approach.
Minimisation of local within‐class variance for image segmentation
Authors: Zhou Dongguo , Zhou Hong
Published: March 2016

In this study, the authors present a clustering‐based thresholding technique for image segmentation. This technique is built on the minimum within‐class variance of a scalable local region that draws upon the previous result and its spatial information to account for the connectivity between the background and the object. The cluster mean derived from the object region in each iteration is considered as an alternative global threshold to prevent the pixels with low intensity from clustering and enable the pixels with similarity to be clustered. This approach makes the method less sensitive to the problem associated with the shape of the histogram and thus leads to an automatic iterated method for a promising segmentation performance. Experiment results on synthetic and real images prove the efficiency of the method.
Fast algorithm for least‐squares based image prediction
Authors: Martchenko Andrew , Deng Guang
Published: March 2016

A new computationally efficient algorithm for two‐dimensional sliding‐window least‐squares prediction is presented in this study. The fast algorithm is based on a recursive update of the Cholesky decomposition. Compared with the state‐of‐the‐art algorithm, the proposed algorithm reduces the computational complexity from O(D3) to O(D2h), where D is the predictor order and h is the height of the prediction patch. The computational improvement is made at the stage of solving the normal equations for which an update algorithm for the Cholesky decomposition of the covariance matrix is proposed. It is shown that a large part of the Cholesky decomposition at location n can be efficiently calculated by performing orthonormal updates on the Cholesky decomposition at n − 1. The computational improvement is made without requiring additional storage space. Extensive experiments using causal and non‐causal predictors of varying shapes and sizes have confirmed that the proposed algorithm is consistently faster than the state‐of‐the‐art algorithm and produces identical prediction images. The efficiency of the proposed algorithm is shown to be affected by the order in which pixels are sampled, thus an ordering procedure is proposed to minimise the number of numerical operations.
Three‐level hysteresis current control strategy for three‐phase four‐switch shunt active filters
Authors: Biricik Samet , Komurcugil Hasan
Published: March 2016

In this study, a three‐level hysteresis current‐control (HCC) strategy is proposed for three‐phase four‐switch shunt active power filters. The four‐switch topology which utilises four switching devices together with two series connected capacitors is able to reduce the cost, switching losses and improve the reliability of system. In this topology, when the current control of phases A and B is achieved successfully, the current control of phase C which is connected to the midpoint of the series connected capacitors is achieved automatically. The current control is achieved by using a three‐level HCC strategy. An important consequence of using this control strategy is that it enables access to the zero level of the input voltage of active filter so that a switching device is only switched when the current error is negative, while it remains off when the current error is positive. Furthermore, the imbalance in the capacitor voltages is eliminated by adding a feedback term (the difference in the capacitor voltages multiplied by a suitable gain) to the current control. The proposed control strategy offers a reduced switching frequency, losses and cost. The steady‐state and dynamic performance of the proposed control strategy is verified through simulations and experimental studies.
DC‐link current estimation for load‐side converter of brushless doubly‐fed generator in the current feed‐forward control
Authors: Wang Xingwei , Lin Hua
Published: March 2016

In the stand‐alone brushless doubly‐fed generator (BDFG) control system, there are two back‐to‐back converters composed of the machine‐side converter (MSC) and the load‐side converter (LSC). The LSC is a three‐phase AC–DC pulse width modulation converter which usually adopts the double‐loop control strategy with outer voltage loop and inner current loop. The introduction of the DC‐link current feed‐forward for improving the dynamic performance of the LSC can reduce the effect of the load disturbance to the system. However, the DC‐link current has a complex harmonic spectrum with the MSC connected to the DC side, so its average value is not convenient to measure. This study presents a DC‐link current estimation algorithm for the current feed‐forward control in the LSC of the stand‐alone BDFG. With the help of the equivalent circuit of the BDFG and the power balance, the rapid calculation of the average DC‐link current can be estimated as well. With this estimation of the current instead of the actual DC‐link current, the DC‐link voltage and AC side current of the LSC can achieve stability quickly. The effectiveness and correction is validated by the simulation and experiments.
A generalized Prandtl-Ishlinskii model for characterizing the rate-independent and rate-dependent hysteresis of piezoelectric actuators
Authors: Gan Jinqiang , Zhang Xianmin , Wu Heng
Published: March 2016

In this paper, a generalized hysteresis model is developed to describe both rate-independent and rate-dependent hysteresis in piezoelectric actuators. Based on the classical Prandtl-Ishlinskii (P-I) model, the developed model adds a quadratic polynomial and makes other small changes. When it is used to describe rate-independent hysteresis, the parameters of the model are constants, which can be identified by self-adaptive particle swarm optimization. The effectiveness of this rate-independent modified P-I model is demonstrated by comparing simulation results of the developed model and the classic Prandtl-Ishlinskii model. Simulation results suggest that the rate-independent modified P-I model can describe hysteresis more precisely. Compared with the classical P-I model, the rate-independent modified P-I model reduces modeling error by more than 50%. When it is used to describe rate-independent hysteresis, a one-side operator is adopted and the parameters are functions with input frequency. The results of the experiments and simulations have shown that the proposed models can accurately describe both rate-independent and rate-dependent hysteresis in piezoelectric actuators.
