An Experimental Comparison of Techniques: Cognitive Defusion, Cognitive Restructuring, and in-vivo Exposure for Social Anxiety
Authors: Barrera Terri L. , Szafranski Derek D. , Ratcliff Chelsea G. , Garnaat Sarah L. , Norton Peter J.
Published: February 2015

Background: One of the primary differences between Cognitive Behavioral Therapy (CBT) and Acceptance and Commitment Therapy (ACT) for anxiety is the approach to managing negative thoughts. CBT focuses on challenging the accuracy of dysfunctional thoughts through cognitive restructuring exercises, whereas ACT attempts to foster acceptance of such thoughts through cognitive defusion exercises. Previous research suggests that both techniques reduce the distress associated with negative thoughts, though questions remain regarding the benefit of these techniques above and beyond exposure to feared stimuli. Aims: In the present study, we conducted a brief experimental intervention to examine the utility of cognitive defusion + in-vivo exposure, cognitive restructuring + in-vivo exposure, and in-vivo exposure alone in reducing the impact of negative thoughts in patients with social anxiety disorder. Method: All participants completed a brief public speaking exposure and those in the cognitive conditions received training in the assigned cognitive technique. Participants returned a week later to complete a second exposure task and self-report measures. Results: All three conditions resulted in similar decreases in discomfort related to negative thoughts. ANOVA models failed to find an interaction between change in accuracy or importance and assignment to condition in predicting decreased distress of negative thoughts. Conclusions: These preliminary results suggest that changes in perceived importance and accuracy of negative thoughts may not be the mechanisms by which cognitive defusion and cognitive restructuring affect distress in the short-term.
Public health care nurses’ views of mothers’ mental health in paediatric healthcare services: a qualitative study
Authors: Borglin Gunilla , Hentzel Johanna , Bohman Doris M.
Published: February 2015

Aim

To investigate public health nurses’ perceptions and experiences of mental health and of the prevention of mental ill health among women postpartum, within paediatric healthcare services.

Background

Although maternal health following childbirth should be a priority within primary care, it is known that women postpartum do not always receive the support they need to adapt to and cope with motherhood. Research implies that postnatal problems lack recognition and are not always acknowledged in routine practice. Few studies have been presented on this topic or from the perspective of nurses.

Methods

For this study, eight semi-structured interviews were conducted with public health nurses, and the transcribed texts were analysed through a process inspired by Burnard’s description of the four-step qualitative content analysis.

Findings

Three categories – external influences on postpartum mental health, screening for and preventing postpartum mental ill health and paediatric healthcare services as a platform for support – were interpreted to reflect the nurses’ perceptions and experiences of mental health among women postpartum and of the prevention of mental ill health among women postpartum.

Conclusion

We found that public health nurses can have an important role in supporting mothers’ mental health postpartum. Although caution is warranted in interpreting our results, the findings concur with those of other studies, highlighting that an equal care emphasis on both the mother and child can be an important aspect of successful support. Implementing person-centred care might be one strategy to create such an emphasis, while also promoting the mental health of new mothers. Public health nurses have a unique opportunity to support mothers’ transition into healthy motherhood, especially because they are likely to meet both mothers and children on a regular basis during the first year after birth.

Nitroxyl (HNO) is a redox sibling of nitric oxide (NO) that targets distinct signalling pathways with pharmacological endpoints of high significance in the treatment of heart failure. Beneficial HNO effects depend, in part, on its ability to release calcitonin gene-related peptide (CGRP) through an unidentified mechanism. Here we propose that HNO is generated as a result of the reaction of the two gasotransmitters NO and H2S. We show that H2S and NO production colocalizes with transient receptor potential channel A1 (TRPA1), and that HNO activates the sensory chemoreceptor channel TRPA1 via formation of amino-terminal disulphide bonds, which results in sustained calcium influx. As a consequence, CGRP is released, which induces local and systemic vasodilation. H2S-evoked vasodilatatory effects largely depend on NO production and activation of HNO–TRPA1–CGRP pathway. We propose that this neuroendocrine HNO–TRPA1–CGRP signalling pathway constitutes an essential element for the control of vascular tone throughout the cardiovascular system.
Indole is an essential herbivore-induced volatile priming signal in maize
Authors: Erb Matthias , Veyrat Nathalie , Robert Christelle A. M. , Xu Hao , Frey Monika , Ton Jurriaan , Turlings Ted C. J.
Published: February 2015

Herbivore-induced volatile organic compounds prime non-attacked plant tissues to respond more strongly to subsequent attacks. However, the key volatiles that trigger this primed state remain largely unidentified. In maize, the release of the aromatic compound indole is herbivore-specific and occurs earlier than other induced responses. We therefore hypothesized that indole may be involved in airborne priming. Using indole-deficient mutants and synthetic indole dispensers, we show that herbivore-induced indole enhances the induction of defensive volatiles in neighbouring maize plants in a species-specific manner. Furthermore, the release of indole is essential for priming of mono- and homoterpenes in systemic leaves of attacked plants. Indole exposure markedly increases the herbivore-induced production of the stress hormones jasmonate-isoleucine conjugate and abscisic acid, which represents a likely mechanism for indole-dependent priming. These results demonstrate that indole functions as a rapid and potent aerial priming agent that prepares systemic tissues and neighbouring plants for incoming attacks.
Observation of coherent oscillation in single-passage Landau-Zener transitions

Published: February 2015

Landau-Zener transition (LZT) has been explored in a variety of physical systems for coherent population transfer between different quantum states. In recent years, there have been various proposals for applying LZT to quantum information processing because when compared to the methods using ac pulse for coherent population transfer, protocols based on LZT are less sensitive to timing errors. However, the effect of finite range of qubit energy available to LZT based state control operations has not been thoroughly examined. In this work, we show that using the well-known Landau-Zener formula in the vicinity of an avoided energy-level crossing will cause considerable errors due to coherent oscillation of the transition probability in a single-passage LZT experiment. The data agree well with the numerical simulations which take the transient dynamics of LZT into account. These results not only provide a closer view on the issue of finite-time LZT but also shed light on its effects on the quantum state manipulation.

Published: February 2015

In this study, we propose and experimentally demonstrate a volumetric display system based on quantum dots (QDs) embedded in a polymer substrate. Unlike conventional volumetric displays, our system does not require electrical wiring; thus, the heretofore unavoidable issue of occlusion is resolved because irradiation by external light supplies the energy to the light-emitting voxels formed by the QDs. By exploiting the intrinsic attributes of the QDs, the system offers ultrahigh definition and a wide range of colours for volumetric displays. In this paper, we discuss the design, implementation and characterization of the proposed volumetric display's first prototype. We developed an 8 × 8 × 8 display comprising two types of QDs. This display provides multicolour three-type two-dimensional patterns when viewed from different angles. The QD-based volumetric display provides a new way to represent images and could be applied in leisure and advertising industries, among others.

Published: February 2015

Members of the inositol phosphate metabolism pathway regulate cell proliferation, migration and phosphatidylinositol-3-kinase (PI3K)/Akt signaling and are frequently dysregulated in cancer. Whether germline genetic variants in inositol phosphate metabolism pathway are associated with cancer risk remains to be clarified. We examined the association between inositol phosphate metabolism pathway genes and risk of eight types of cancer using data from genome-wide association studies. Logistic regression models were applied to evaluate SNP-level associations. Gene- and pathway-based associations were tested using the permutation-based adaptive rank-truncated product method. The overall inositol phosphate metabolism pathway was significantly associated with risk of lung cancer (P = 2.00 × 10−4), esophageal squamous cell carcinoma (P = 5.70 × 10−3), gastric cancer (P = 3.03 × 10−2) and renal cell carcinoma (P = 1.26 × 10−2), but not with pancreatic cancer (P = 1.40 × 10−1), breast cancer (P = 3.03 × 10−1), prostate cancer (P = 4.51 × 10−1) and bladder cancer (P = 6.30 × 10−1). Our results provide a link between inherited variation in the overall inositol phosphate metabolism pathway and several individual genes and cancer. Further studies will be needed to validate these positive findings and to explore its mechanisms.
Surface structure determines dynamic wetting

Published: February 2015

Liquid wetting of a surface is omnipresent in nature and the advance of micro-fabrication and assembly techniques in recent years offers increasing ability to control this phenomenon. Here, we identify how surface roughness influences the initial dynamic spreading of a partially wetting droplet by studying the spreading on a solid substrate patterned with microstructures just a few micrometers in size. We reveal that the roughness influence can be quantified in terms of a line friction coefficient for the energy dissipation rate at the contact line and that this can be described in a simple formula in terms of the geometrical parameters of the roughness and the line-friction coefficient of the planar surface. We further identify a criterion to predict if the spreading will be controlled by this surface roughness or by liquid inertia. Our results point to the possibility of selectively controlling the wetting behavior by engineering the surface structure.
Defoliation of interior Douglas-fir elicits carbon transfer and stress signalling to ponderosa pine neighbors through ectomycorrhizal networks
Authors: Song Yuan Yuan , Simard Suzanne W. , Carroll Allan , Mohn William W. , Zeng Ren Sen
Published: February 2015

Extensive regions of interior Douglas-fir (Pseudotsuga menziesii var. glauca, IDF) forests in North America are being damaged by drought and western spruce budworm (Choristoneura occidentalis). This damage is resulting from warmer and drier summers associated with climate change. To test whether defoliated IDF can directly transfer resources to ponderosa pine (Pinus ponderosae) regenerating nearby, thus aiding in forest recovery, we examined photosynthetic carbon transfer and defense enzyme response. We grew pairs of ectomycorrhizal IDF ‘donor’ and ponderosa pine ‘receiver’ seedlings in pots and isolated transfer pathways by comparing 35 μm, 0.5 μm and no mesh treatments; we then stressed IDF donors either through manual defoliation or infestation by the budworm. We found that manual defoliation of IDF donors led to transfer of photosynthetic carbon to neighboring receivers through mycorrhizal networks, but not through soil or root pathways. Both manual and insect defoliation of donors led to increased activity of peroxidase, polyphenol oxidase and superoxide dismutase in the ponderosa pine receivers, via a mechanism primarily dependent on the mycorrhizal network. These findings indicate that IDF can transfer resources and stress signals to interspecific neighbors, suggesting ectomycorrhizal networks can serve as agents of interspecific communication facilitating recovery and succession of forests after disturbance.

Soft repulsive interactions, particle rearrangements and size selection in the self-assembly of nanoparticles at liquid interfaces
Authors: Schwenke Konrad , Del Gado Emanuela
Published: February 2015

In the adsorption of nanoparticles at liquid interfaces, soft and short ranged repulsive effective interactions between the nanoparticles at the interface may eventually induce crowding, slow dynamics and jamming at high surface coverage. These phenomena can interfere during the adsorption process, significantly slowing down its kinetics. Here, by means of numerical simulations, we find that modifying the effective interactions, which can be achieved for example by grafting differently functionalized polymer shells on the bare nanoparticles, may qualitatively change such interplay. In particular our results suggest that, in the presence of ultrasoft particle interactions such as the ones described by a Gaussian Core Model potential, a small size polydispersity can be sufficient to decouple the adsorption kinetics from the slow dynamics that develops at the interface, due to a qualitative change from an irreversible adsorption controlled by particle rearrangements at the interface to one dominated by size selection mechanisms. These findings may be useful to achieve higher surface coverages and faster adsorption kinetics.

Dispensability of zinc and the putative zinc-binding domain in bacterial glutamyl-tRNA synthetase
Authors: Chongdar Nipa , Dasgupta Saumya , Datta Ajit Bikram , Basu Gautam
Published: February 2015

The putative zinc-binding domain (pZBD) in Escherichia coli glutamyl-tRNA synthetase (GluRS) is known to correctly position the tRNA acceptor arm and modulate the amino acid-binding site. However, its functional role in other bacterial species is not clear since many bacterial GluRSs lack a zinc-binding motif in the pZBD. From experimental studies on pZBD-swapped E. coli GluRS, with Thermosynechoccus elongatus GluRS, Burkholderia thailandensis GluRS and E. coli glutamyl-queuosine-tRNAAsp synthetase (Glu-Q-RS), we show that E. coli GluRS, containing the zinc-free pZBD of B. thailandensis, is as functional as the zinc-bound wild-type E. coli GluRS, whereas the other constructs, all zinc-bound, show impaired function. A pZBD-tinkered version of E. coli GluRS that still retained Zn-binding capacity, also showed reduced activity. This suggests that zinc is not essential for the pZBD to be functional. From extensive structural and sequence analyses from whole genome database of bacterial GluRS, we further show that in addition to many bacterial GluRS lacking a zinc-binding motif, the pZBD is actually deleted in some bacteria, all containing either glutaminyl-tRNA synthetase (GlnRS) or a second copy of GluRS (GluRS2). Correlation between the absence of pZBD and the occurrence of glutamine amidotransferase CAB (GatCAB) in the genome suggests that the primordial role of the pZBD was to facilitate transamidation of misacylated Glu-tRNAGln via interaction with GatCAB, whereas its role in tRNAGlu interaction may be a consequence of the presence of pZBD.
Optimal power flow in the presence of wind power using modified cuckoo search
Authors: Mishra Chetan , Singh Shiv P. , Rokadia Jimit
Published: February 2015

This study proposes a solution to the optimal power flow (OPF) in power systems incorporating wind power. The wind generated electricity's cost modelling is presented which owes to the stochastic nature of wind speed based on the Weibull probability density function. The wind associated costs comprise of (i) reserve cost arising out of overestimation of wind farm output and (ii) penalty cost for not using total available wind power which are included in the conventional OPF. Furthermore, the Q‐V formulation of induction generator is deduced which is incorporated through a modification in the conventional load flow solution. A modified cuckoo search optimisation technique is employed and compared with modified particle swarm optimisation for solving OPF with wind power involved. A modified IEEE 30‐bus and IEEE 57‐bus systems are used as test systems and it is observed that the cuckoo search performs better than particle swarm optimisation.
Analysis and control of capacitor‐excited induction generators connected to a micro‐grid through power electronic converters
Authors: Senthil Kumar Subramaniam , Kumaresan Natarajan , Subbiah Muthiah
Published: February 2015

A system consisting of a capacitor‐excited induction generator (CEIG) with associated power electronic converters has been developed for supplying power to a micro‐grid. The power fed to the grid from the CEIG is controlled using a diode bridge rectifier (DBR) and a pulse width modulated (PWM) inverter, connected between the generator terminals and the grid. A simple analog based hysteresis current control (HCC) technique has been employed in which the current control of the PWM inverter alone needs to be carried out by sensing the current and voltage at the grid terminals. The successful working of the system has been demonstrated for three different patterns of feeding power to a micro‐grid, by experiments conducted on a three‐phase 230 V, 3.7 kW CEIG, with a 100 µF delta connected excitation capacitor bank and employing the controllers fabricated in the laboratory. The grid power is represented as an equivalent load resistance in the steady‐state equivalent circuit of the CEIG and the technique of genetic algorithm (GA) has been adopted for the analysis of the proposed system. The predetermined performance characteristics of the system and the results of Matlab/Simulink simulation studies have also been presented.
Probabilistic spinning reserve adequacy evaluation for generating systems using an Markov chain Monte Carlo‐integrated cross‐entropy method
Authors: Wang Yue
Published: February 2015

Spinning reserve plays an important role in balancing generation and demand mismatch within a short time interval. Probabilistic spinning reserve adequacy evaluation (PSRAE) is useful to aid operators in monitoring the adequacy of system upward spinning reserve exposed to unforeseen disturbances and making risk‐adverse decisions for unit dispatching. As a short time period, for example, 30 s–15 min, is usually considered in PSRAE, the generating system in question is commonly of high reliability, which renders naive non‐sequential Monte Carlo methods inefficient. In this study, the high reliability phenomenon of generating systems is explained through a toy case study, thereafter, aiming to develop an efficient method for PSRAE, a simulation method based on the cross‐entropy which has been widely applied in many areas to improve naive Monte Carlo methods for tackling rare‐event simulation issues, integrated with Markov chain Monte Carlo is proposed. The indices of loss of load probability and expected demand not supplied are used to quantify the spinning reserve inadequacy risk. Through case studies conducted on the RTS‐79, usefulness of the PSRAE is discussed and the proposed method is proven to be superior to the classical cross‐entropy method and thus could be taken as a candidate tool for the PSRAE to practical systems.
